                               INTRODUCTION

     The Annual Meeting of Shareholders of AVECOR Cardiovascular Inc. (the
"Company") will be held on Thursday, May 7, 1998, at 3:30 p.m. local time, at
the Minneapolis Marriott City Center Hotel, 30 South Seventh Street,
Minneapolis, Minnesota, or at any adjournment thereof (the "Annual Meeting"),
for the purposes set forth in the Notice of Meeting.

     A proxy card is enclosed for your use.  You are solicited on behalf of the
Board of Directors to MARK, SIGN AND RETURN THE PROXY CARD IN THE ACCOMPANYING
ENVELOPE.  No postage is required if mailed within the United States.  The cost
of soliciting proxies, including the preparation, assembly and mailing of the
proxies and soliciting material, as well as the cost of forwarding such material
to the beneficial owners of Common Stock, will be borne by the Company. 
Directors, officers and regular employees of the Company may, without
compensation other than their regular compensation, solicit proxies by
telephone, telegraph or personal conversation.  The Company may reimburse
brokerage firms and others for expenses in forwarding proxy material to the
beneficial owners of Common Stock.

     Any proxy given to this solicitation and received in time for the Annual
Meeting will be voted in accordance with the instructions given in such proxy. 
Any shareholder giving a proxy may revoke it any time prior to its use at the
Annual Meeting by giving written notice of such revocation to the Secretary of
the Company, by filing a revoking instrument or a duly executed proxy bearing a
later date with the Secretary of the Company or by attending the Annual Meeting
and voting in person.  Proxies that are signed by shareholders but that lack any
specific voting instructions will be voted in favor of the proposals set forth
in the Notice of Meeting and in favor of the election as directors of each of
the nominees listed in this Proxy Statement.

     THE BOARD RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR THE APPROVAL OF THE
PROPOSALS SET FORTH IN THE NOTICE OF MEETING AND FOR EACH OF THE NOMINEES NAMED
HEREIN.

     The Company expects that this Proxy Statement, the Proxy and Notice of
Meeting will first be mailed to shareholders on or about March 27, 1998.

                              VOTING OF SHARES

     The close of business on Friday, March 13, 1998 has been fixed by the Board
of Directors of the Company (the "Board") as the record date for the
determination of shareholders entitled to notice of and to vote at the Annual
Meeting.  On March 13, 1998, the Company had outstanding 8,020,562 shares of
Common Stock, $.01 par value (the "Common Stock"), each such share entitling the
holder thereof to one vote in person or by proxy on each matter to be voted on
at the Annual Meeting, voting together as a single class.

     The presence at the Annual Meeting, in person or by proxy, of the holders
of a majority of the outstanding shares of Common Stock entitled to vote at the
meeting is required for a quorum for the transaction of business.  In general,
shares of Common Stock represented by a properly signed and returned proxy card
will be counted as shares present and entitled to vote at the meeting for
purposes of determining a quorum, without regard to whether the card reflects
abstentions (or is left blank) or reflects a "broker non-vote" on a matter
(i.e., a card returned by a broker on behalf of its beneficial owner customer
that is not voted on a particular matter because voting instructions have not
been received and the broker has no discretionary authority to vote).

     The election of a nominee for director and the approval of each of the
other proposals described in this Proxy Statement require the approval of a
majority of the shares present and entitled to vote in person or by proxy on
that matter (and at least a majority of the minimum number of votes necessary
for a quorum to transact business at the Annual Meeting).  Shares represented by
a proxy card voted as abstaining on any of the proposals will be treated as
shares present and entitled to vote that were not cast in favor of a particular
matter, and thus will be counted as votes against that matter.  Shares
represented by a proxy card including any broker non-vote on a matter will be
treated as shares not entitled to vote on that matter, and thus will not be
counted in determining whether that matter has been approved.


                        SECURITY OWNERSHIP OF CERTAIN

ADDITIONAL INFORMATION ABOUT THE BOARD AND ITS COMMITTEES

     Standing committees of the Board of Directors include the Audit Committee
and Compensation Committee.

     THE AUDIT COMMITTEE.  The Audit Committee is responsible for matters
related to accounting policies and practices, financial reporting and internal
controls.  The Audit Committee reviews with representatives of the Company's
independent auditors the scope of the audit of the Company's financial
statements, the results of audits, audit fees and any recommendations with
respect to internal controls and financial matters.  The Audit Committee
consists of Messrs. Strickland and Wright.  In December, 1997 the Audit
Committee met to review the 1996 audit, the Company's accounting policies and
the scope of the 1997 audit. 

     THE COMPENSATION COMMITTEE.  The Compensation Committee reviews general
programs of compensation and benefits for all employees of the Company, makes
recommendations to the Board concerning such matters as compensation to be paid
to the Company's officers and directors and administers the Company's 1991 Stock
Incentive Plan, as amended (the "1991 Plan"), Employee Stock Purchase Plan (the
"Purchase Plan") and 1995 Non-Employee Director Option Plan (the "Director
Plan").  The Compensation Committee consists of Messrs. Strickland and Stassen. 
The Compensation Committee met once and took action by written consent fifteen
times during 1997.  These written actions were taken to make grants of stock
options to the employees of the Company, with the majority of such grants being
made to new employees.

     The Company's Board of Directors met four times during fiscal 1997.  All of
the directors attended 75% or more of the combined total number of meetings of
the Board of Directors and committees on which they served during 1997.  

DIRECTOR COMPENSATION

     DIRECTORS' FEES.  Directors who are employees of the Company receive no
separate compensation for their services as directors.  Non-employee directors
of the Company currently receive a retainer of $1,000 per month and compensation
of $750 for each Board meeting attended in person.  Directors are also
reimbursed for travel and lodging expenses incurred while attending Board
meetings or 

                                       6
<PAGE>

otherwise engaging in Company business.  Committee members do not 
receive any additional compensation by reason of their service on such 
committee(s).

     STOCK-BASED COMPENSATION.  On August 1, 1995, the Board adopted the
Director Plan, which was approved by the shareholders at the Company's 1996
annual meeting.  

     The Director Plan provides that each non-employee director serving on the
Board on, or appointed or elected to the Board after, August 1, 1995 will be
granted, on a one-time basis, an option to purchase 10,500 shares of Common
Stock upon such non-employee director's Initial Election.  "Initial Election"
means, in the case of a non-employee director serving on the Board as of August
1, 1995, such date, or, in the case of a non-employee director elected or
appointed to the Board after August 1, 1995, the date on which such director is
first elected or appointed.  In addition, each non-employee director who
continues to serve the Company in such capacity will be granted an option to
purchase 3,500 shares of Common Stock at the conclusion of each annual meeting
of the Company's shareholders occurring after the second anniversary of his or
her Initial Election.  

     Options granted in connection with a non-employee director's Initial
Election become exercisable in equal one-third increments on the date of Initial
Election and the first and second anniversary of the date of Initial Election. 
Options granted in connection with an annual meeting become exercisable in full
on the first anniversary of the date of grant.  Options under the Director Plan
have an exercise price per share equal to 100% of the fair market value of one
share of Common Stock on the date of grant.  Each option expires and remains
exercisable until the tenth anniversary after its date of grant.  Pursuant to
the Director Plan, an option will become immediately and fully exercisable for a
period of three months after the termination of service of a non-employee
director as a director of the Company, except that, if termination of service is
due to death, disability or retirement, an option will remain exercisable for a
period of one year, but never beyond the option's original term.  In the event
of a change in control of the Company, the Director Plan provides that all
options will become immediately and fully exercisable for the remainder of their
respective terms.

     On December 11, 1997, the Company granted to each non-employee director
options to purchase 15,000 shares of Common Stock under the Company's 1991 Plan.
This grant is subject, however, to shareholder approval at the Annual Meeting of
the proposal to increase the number of shares issuable under the 1991 Plan.  See
"New Plan Benefits."

(1)  All options granted to the executives indicated were granted under 
     the 1991 Plan at the fair market value of the Company's Common Stock on 
     the date of grant as reported on the Nasdaq National Market.  All stock 
     options indicated will become exercisable at the rate of one quarter of 
     the number of shares underlying the option on each of the four 
     anniversaries of the date of grant.  In the event of a "change in 
     control," as defined in the 1991 Plan, all outstanding options become 
     immediately exercisable in full and will remain so for the remainder of 
     their term regardless of whether the holder remains in the employ or 
     service of the Company.
     
(2)  Represents the present value of the options granted on the date of 
     grant using the Black-Scholes option pricing model, which requires the 
     assumption of certain values.  In calculating the values shown, the 
     Company assumed annualized volatility of the price of Common Stock of 
     50%, time of exercise or option life ranging from 4.3 to 8 years, and 
     risk-free interest rates ranging from 5.8% to 6.6%, determined from 
     market information as of the respective dates of grant. No adjustments 
     were made for the non-transferability or risk of forfeiture of the 
     options, and, because the Company has historically not paid dividends 
     on Common Stock, no yield on Common Stock was assumed.  There can be no 
     assurance that these assumptions will prove true in the future.  The 
     actual value, if any, that an executive may realize will depend on the 
     excess of the market price of Common Stock over the exercise price on 
     the date the option is exercised, which may vary from the theoretical 
     value indicated in the table.
     
(3)  Includes 5,000 shares of Common Stock which are subject to 
     shareholder approval at the Annual Meeting of the proposal to increase 
     the number of shares issuable under the 1991 Plan.  See "New Plan 
     Benefits."

MANAGEMENT AGREEMENTS

     CONFIDENTIALITY AGREEMENTS.  Each of the executive officers named in the 
Summary Compensation Table above has entered into an Agreement Regarding 
Non-Disclosure of Confidential Information, Non-Competition and Ownership of 
Intellectual Property with the Company.  In addition to certain 
confidentiality and non-disclosure obligations, these agreements provide that 
the named executive officer will not participate in or support the 
manufacture, invention, development, sale, solicitation of sale, marketing, 
testing, research or other business aspect of any product competitive with 
the Company's actual or projected products during the named executive 
officer's term of employment and for a period of two (2) years thereafter 
(or, if employed by the Company for less than two years, the period of such 
employment or one (1) year, whichever is greater).  

     In consideration for the agreement of each named executive officer not to
compete with the Company, the Company has agreed to pay each executive, on a
monthly basis, 75% of such executive's average monthly base salary (or, in the
case of Messrs. Badolato or Seck, the greater of $6,250 or 75% of such
executive's average monthly base salary), less any compensation which such
executive has an unqualified right to receive, should such executive's
employment with the Company be terminated. These payments commence with the
fourth month after termination and are conditioned on efforts by the executive
to seek employment consistent with the executive's education, abilities and
experience and which would not violate the non-competition provisions.  The
payments continue until the earlier of the expiration or waiver by the Company
of the non-competition provision or the failure by the executive to fulfill the
conditions to such payments.

     CHANGE IN CONTROL AGREEMENTS.  In April 1996, the Company entered into
Change in Control letter agreements ("Change in Control Agreements") with each
of the  executive officers named in the 

                                       10
<PAGE>


Summary Compensation Table above.  Under the Change in Control Agreements, an 
executive of the Company is entitled to receive certain benefits if, within 
twelve months after a "change in control," the executive is terminated by the 
Company for any reason other than death, disability, retirement or "cause" 
(as defined in the Change in Control Agreement) or leaves voluntarily for a 
"good reason" (which includes adverse changes in the executive's status or 
position, reduction in base salary, material adverse changes in benefit plans 
or relocation).  In such a case, the Company (or its successor) would be 
required to make a lump-sum cash payment to the executive in an amount equal 
to twenty four (24) times the executive's "highest monthly compensation."  
For purposes of the Change in Control Agreements, "highest monthly 
compensation" is defined as one-twelfth of the highest amount of the 
executive's compensation for any 12 consecutive calendar month-period during 
the 36 consecutive calendar-month period prior to the month of the 
executive's termination.  The executive would also be entitled to continued 
coverage under the Company's welfare plans for up to 24 months.  

     A "change in control" for purposes of the Change in Control Agreements is
defined to include (a) a transfer of substantially all of the Company's assets;
(b) approval by the stockholders of the Company of any plan or proposal for
liquidation or dissolution of the Company; or (c) a change in control of a
nature that would be required to be reported to the Securities and Exchange
Commission in response to Item 1(a) of Form 8-K.  Additionally, the Change in
Control Agreements provide that, without limitation, a "change in control" will
be deemed to have occurred at such time as (i) any person or group becomes the
beneficial owner of 50% or more of the voting power of the Company's outstanding
voting stock ordinarily entitled to vote at elections of directors; or (ii) the
"incumbent board" (generally defined as the current directors and their future
nominees) cease to constitute a majority of the Board.  The Change in Control
Agreements are designed to attract and retain valued executives of the Company
and to ensure that the performance of these executives is not undermined by the
possibility, threat or occurrence of a change in control.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The Compensation Committee of the Board of Directors makes recommendations
to the Board of Directors concerning the compensation of the Company's executive
officers and directors, and acts on such other matters relating to their
compensation as it deems appropriate.  In addition, the Compensation Committee
administers the Company's stock-based compensation plans, including the 1991
Plan, pursuant to which incentive stock options, non-statutory stock options,
restricted stock awards and stock bonuses may be granted to eligible key
employees, officers, directors and consultants of the Company.

     COMPENSATION PHILOSOPHY AND OBJECTIVES.  The philosophy underlying the
decisions and recommendations of the Compensation Committee is to recognize and
reward results and achievement at the individual and Company level by linking
compensation to such achievement.  Consistent with this philosophy, the
Compensation Committee has set the following objectives for the Company's
executive compensation program:

     -    Encourage the achievement of desired individual and Company
          performance goals by rewarding such achievements.
  
     -    Provide a program of compensation that is competitive with
          comparable companies to enable the Company to attract and retain key
          executive talent.
  
     -    Align the interests of the Company's executives with the
          interests of its shareholders by linking compensation to the Company's
          performance and by 

                                       11
<PAGE>

          providing the Company's executives with long-term opportunities for 
          stock ownership.


     In determining its recommendations as to the compensation of the Company's
executives, the Compensation Committee considers factors such as Company
performance, both in isolation and in comparison to companies of comparable
profitability, complexity and size; the individual performance of each executive
officer; historical compensation levels at the Company; the overall competitive
environment for executives and the level of compensation necessary to attract
and retain the level of key executive talent desired by the Company.  In
analyzing these factors, the Compensation Committee may from time to time review
competitive compensation data gathered in comparative surveys or collected by
independent consultants.

     EXECUTIVE COMPENSATION PROGRAM COMPONENTS.  The Company's executive
compensation program consists of base salary, annual cash incentive compensation
opportunities, and long-term incentive opportunities under the 1991 Plan.  Each
element of the compensation program is discussed in greater detail below.

          BASE SALARY.  The base salary of the executive officers of the
     Company, including the Chief Executive Officer, is determined annually by
     the Compensation Committee and ratified by the Board of Directors after
     considering the compensation levels of personnel with similar
     responsibilities at comparable companies in the medical device industry,
     the potential impact of the individual on the Company's performance, the
     level of skill, responsibility and experience required by the individual's
     position and the other factors described above.  Decisions concerning the
     salaries of executive officers are made by the Compensation Committee after
     a process that includes a review of the Chief Executive Officer's
     recommendations with regard to the salaries of all executives officers
     other than the Chief Executive Officer.  Base salaries are determined for
     each year prior to the beginning of the year.  
     
          For 1997, the base salaries of Messrs. Badolato, Melsen and Seck were
     increased after an assessment of the foregoing factors by the Compensation
     Committee, as well as an assessment of comparative data relating to
     compensation of chief executive officers, chief financial officers, and
     vice presidents of sales and marketing, respectively.  The increase in Mr.
     Melsen's base salary for 1997 was made after also considering his
     responsibilities and contributions during his first year with the Company. 
     The increase in Mr. Seck's base salary for 1997 was made after also
     considering that his base salary for 1996 remained unchanged from his base
     salary for 1995.  

          ANNUAL CASH BONUSES.  The Compensation Committee utilizes annual cash
     bonuses to provide a direct financial incentive to the Company's executive
     officers.  Under the executive officer bonus program administered by the
     Compensation Committee, an executive may receive a bonus ranging from 0% to
     40% of such executive's base salary, with the amount of potential bonus
     determined by achievement of budgeted pre-tax income target levels for the
     fiscal year.  It is the objective of the Compensation Committee to link
     such bonuses to the financial and overall performance of the Company, the
     achievement of desired individual performance goals and the competitive
     levels of bonuses at comparable companies.  Based upon these factors, and,
     in particular, upon the Company's financial performance during 1997, no
     bonuses were paid to or accrued for any of the Company's executive officers
     for 1997. 

          LONG-TERM INCENTIVE COMPENSATION.  The Compensation Committee makes
     long-term incentive compensation available to the Company's executive
     officers through its administration 

                                       12
<PAGE>

     of the 1991 Plan, as discussed above. The purpose of the 1991 Plan is to 
     advance the interests of the Company and its shareholders by enabling the 
     Company to attract and retain persons of ability to perform services for 
     the Company, including persons performing services to the Company as 
     executive officers.  The 1991 Plan provides an incentive to such persons 
     through equity participation in the Company and by rewarding such persons 
     who contribute to the Company's achievement of its financial objectives.  
     During 1997, Mr. Seck, Mr. Melsen and Mr. Haworth were each granted 
     options under the 1991 Plan.  In December 1997, the Company also granted 
     Mr. Badolato options to purchase 50,000 shares of Common Stock with options
     to purchase 5,000 of such shares granted subject to shareholder approval 
     at the Annual Meeting of the proposal to increase the number of shares 
     issuable under the 1991 Plan.  The options provided to the named 
     executives were granted in lieu of base compensation increases
     for 1998 and to provide adequate incentive to such executives both to
     remain with the Company and to assist the Company in achieving its 
     long-term strategies. 

     SECTION 162(m).  Section 162(m) of the Internal Revenue Code of 1986, as
amended (the "Code"), limits the deductibility of certain compensation paid to
the chief executive officer and each of the four other most highly compensated
executives of a publicly held corporation to $1,000,000.  In 1997, the Company
did not pay "compensation" within the meaning of Section 162(m) to such
executive officers in excess of $1,000,000, and does not believe it will do so
in the near future.  Therefore, the Company does not have a policy at this time
regarding qualifying compensation paid to its executive officers for
deductibility under Section 162(m), but will formulate such a policy if
compensation levels ever approach $1 million.

                              COMPENSATION COMMITTEE

                              Edward E. Strickland, CHAIRMAN

PROPOSAL TO AMEND THE COMPANY'S 1991 STOCK INCENTIVE PLAN

INTRODUCTION

     The Company's 1991 Plan was first approved by the Board of Directors of the
Company in April 1991 and adopted by the Company's shareholders in June 1991. 
In January, 1996, the Board amended the 1991 Plan to increase the number of
shares of Common Stock reserved for issuance under the 1991 Plan from 750,000
shares to 1,050,000 shares, which amendment was approved by the shareholders in
May, 1996.  The 1991 Plan, as amended, currently provides for the grant to
eligible key employees, officers, directors and consultants of the Company of
stock options ("Options"), including both incentive stock options ("Incentive
Options") and non-statutory stock options ("Non-Statutory Options"), Restricted
Stock Awards and Stock Bonuses.  Options, Restricted Stock Awards and Stock
Bonuses are collectively referred to herein as "Incentive Awards."  

     On December 11, 1997, the Board again amended the 1991 Plan, subject to
shareholder approval, to increase the number of shares of Common Stock reserved
for issuance under the 1991 Plan by 450,000 shares, from 1,050,000 shares to
1,500,000 shares.  The Company's shareholders are being asked to approve this
amendment at the Annual Meeting.

REASONS FOR AMENDMENT

     The increase in the number of shares of Common Stock reserved for issuance
under the 1991 Plan from 1,050,000 shares to 1,500,000 shares is necessary to
permit the Company to continue the operation of the 1991 Plan for the benefit of
new participants, as well as to allow additional awards to current participants
in the 1991 Plan.  As of December 31, 1997, the Company had issued options to
purchase an aggregate of 1,030,000 shares of Common Stock under the 1991 Plan. 
Further, the Board has granted Options to purchase an aggregate of 50,000 shares
of Common Stock under the 1991 Plan, subject to shareholder approval of this
proposal.  See "New Plan Benefits" below.  If this proposal is approved, 420,000
shares of Common Stock will be available for future grants under the 1991 Plan.

SUMMARY OF THE 1991 PLAN

     The major features of the 1991 Plan are summarized below, which summary is
qualified in its entirety by the actual text of the 1991 Plan.  The Company will
furnish without charge a copy of the 1991 Plan to any shareholder of the Company
as of March 13, 1998, upon receipt from any such person of an oral or written
request for the 1991 Plan.  Such request should be sent to the Company at AVECOR
Cardiovascular Inc., 7611 Northland Drive, Minneapolis, Minnesota  55428, Attn: 
Shareholder Relations, or made by telephone at (612) 391-9000.

     GENERAL.  The purpose of the 1991 Plan is to advance the interests of the
Company and its shareholders by enabling the Company to attract and retain
persons of ability to perform services for the Company by providing an incentive
to such persons through equity participation in the Company and rewarding such
persons who contribute to the achievement of the Company's economic objectives. 
All employees (including officers and directors who are also employees) and all
non-employee consultants and directors of the Company or any subsidiary are
eligible to participate in the 1991 Plan.  As of December 31, 1997 approximately
350 individuals were eligible to participate in the 1991 Plan.  

     The 1991 Plan, as amended, currently provides for the granting of Incentive
Awards covering up to an aggregate of 1,500,000 shares of Common Stock to
eligible persons.  The Board may amend the 

                                       15
<PAGE>

1991 Plan in any respect without shareholder approval, unless shareholder 
approval is required by Rule 16b-3 under the Securities Exchange Act of 1934, 
as amended (the "Exchange Act"), or any successor rule, the rules of the 
Nasdaq National Market or Section 422 of the Code.  The 1991 Plan terminates 
on April 11, 2001 and may be terminated before that date by action of the 
Board.  Termination of the 1991 Plan by action of the Board will not impair 
any outstanding Incentive Awards except that the Board may continue to take 
any appropriate action with regard to adjustments to Incentive Awards or upon 
a Change in Control, as described below.

     ADMINISTRATION.  The 1991 Plan is currently administered by the
Compensation Committee of the Board of Directors.  The Compensation Committee
has the authority to (a) select the eligible recipients who will be granted one
or more Incentive Awards under the 1991 Plan ("Participants"); (b) determine the
nature and extent of the Incentive Awards to be made to each Participant
(including the number of shares of Common Stock to be subject to each Incentive
Award, any exercise price and the manner in which Incentive Awards will vest or
become exercisable); (c) determine the time or times at which the Incentive
Awards are to be granted; (d) determine the duration of each Incentive Award;
(e) determine the restrictions and other conditions to which the payment or
vesting of Incentive Awards may be subject; and (f) fix such other provisions of
the Incentive Awards as the Compensation Committee deems necessary or desirable
in accordance with the terms of the 1991 Plan.  The Compensation Committee also
determines the form of the agreements with Participants which evidence the
particular terms, conditions, rights and duties with respect to Incentive Awards
granted pursuant to the 1991 Plan.  The Compensation Committee may modify the
terms of an outstanding Incentive Award in any manner (with the consent of the
affected Participant for most modifications) as long as the modified terms are
permitted by the 1991 Plan as then in effect.

     TYPES OF INCENTIVE AWARDS AVAILABLE.  Options must be granted with an
exercise price equal to at least the fair market value of the Common Stock on
the date of grant (85% of the fair market value with respect to Non-Statutory
Options).  Fair market value of the Common Stock is the average of the high and
low prices of the Common Stock, as reported on the Nasdaq National Market on the
applicable date.  On March 13, 1998, the last sale price of the Common Stock was
$7.125 per share, as reported on the Nasdaq National Market.  Generally, Options
will have a maximum term fixed by the Compensation Committee, not to exceed 10
years from the date of grant.  The aggregate fair market value of shares of
Common Stock with respect to which Incentive Options (within the meaning of
Section 422 of the Code) become exercisable for the first time by a participant
during any calendar year may not exceed $100,000.  The exercise price of Options
must be paid in cash, except that the Compensation Committee may allow payment
to be made (in whole or in part) by delivery of a "broker exercise notice"
(pursuant to which the broker or dealer is instructed to sell enough shares or
loan the optionee enough money to pay the exercise price and to remit such sums
to the Company) or promissory note or by transfer of shares of Common Stock
(either previously owned by the optionee or to be acquired upon Option
exercise).

     A Restricted Stock Award is an award of Common Stock that vests at such
times and in such installments as may be determined by the Compensation
Committee and, until it vests, is subject to restrictions on transferability and
the possibility of forfeiture.  The Compensation Committee may impose such
restrictions or conditions to the vesting of Restricted Stock Awards as it deems
appropriate.  A Stock Bonus is an award of Common Stock that is not subject to
any restrictions other than restrictions on transferability.

     EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE.  If a Participant
ceases to be employed by or render other services to the Company and all
subsidiaries ("Termination of Employment") due to death, "Disability" or
"Retirement," as such terms are defined in the 1991 Plan, (a) all outstanding

                                       16
<PAGE>

Options then held by the Participant will become immediately exercisable in 
full and will remain exercisable for a period of one year (in the case of 
death or disability) after the date of Termination of Employment, but in no 
event after the expiration date of any Option; (b) all outstanding Options 
then held by the Participant will remain exercisable to the extent 
exercisable as of the date of Termination of Employment for a period of three 
months (in the case of retirement) after the date of Termination of 
Employment, but in no event after the expiration date of any Option; and (c) 
all Restricted Stock Awards then held by the Participant will become fully 
vested and such shares of Common Stock related thereto will become fully 
non-forfeitable.  As used in the 1991 Plan, "Disability" means the disability 
of the Participant as defined in the long-term disability plan of the Company 
then covering the Participant or, if no such plan exists, the permanent and 
total disability of the Participant within the meaning of Section 22(e)(3) of 
the Code and "Retirement" means the regular retirement of a Participant or, 
if approved by the Board for the purposes of the 1991 Plan, early retirement 
pursuant to and in accordance with the retirement or pension plan or practice 
of the Company then covering the Participant.

     Upon Termination of Employment for any reason other than death, Disability
or Retirement, all rights of the Participant under the 1991 Plan will
immediately terminate without notice of any kind, no Options then held by the
Participant will thereafter be exercisable and all Restricted Stock Awards then
held by the Participant will be forfeited; provided, however, that if such
termination is due to any reason other than voluntary termination by the
Participant or termination by the Company or any subsidiary for "cause" (as
defined in the 1991 Plan), all outstanding Options will remain exercisable to
the extent they are exercisable for a period of three months from the date of
Termination of Employment.

     CHANGE OF CONTROL.  Upon a defined "Change in Control" of the Company, all
outstanding Options become immediately exercisable in full and will remain
exercisable for the remainder of their terms regardless of whether the holder
remains in the employ or service of the Company, and all restrictions with
respect to any outstanding Restricted Stock Awards immediately lapse and the
shares related thereto become non-forfeitable.  A "Change in Control" of the
Company for purposes of the 1991 Plan includes (a) the sale, lease, exchange or
other transfer of all or substantially all of the assets of the Company to, or
the merger or consolidation of the Company with, a corporation that is not
controlled by the Company; (b) the approval by the Company's shareholders of any
plan of liquidation or dissolution of the Company; (c) any person becomes, after
the effective date of the 1991 Plan, the "beneficial owner" (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly of 50% or more of the
combined voting power of the Company's outstanding securities ordinarily having
the right to vote at elections of directors; (d) individuals constituting the
Board of Directors on the effective date of the 1991 Plan cease for any reason
to constitute at least a majority of the directors, provided that any person
becoming a director subsequent to the effective date of the 1991 Plan whose
election, or nomination for election by the Company's shareholders, was approved
by a majority of the directors comprising the Board of Directors on the
effective date of the 1991 Plan (either by specific vote or by approval of the
proxy statement of the Company in which such person is named as a nominee for
director, without objection to such nomination) shall be considered as though
such person were a member of the Board on the effective date of the 1991 Plan;
or (e) any other change in control of the Company of a nature that would be
required to be reported pursuant to Section 13 or 15(d) of the Exchange Act,
whether or not the Company is then subject to such reporting requirements.

FEDERAL INCOME TAX CONSEQUENCES

     The following general description of federal income tax consequences is
based upon current statutes, regulations and interpretations.  The description
does not include state, local or foreign income tax consequences.  This
description is not intended to address specific tax consequences applicable to
an 

                                       17
<PAGE>

individual participant who receives an Incentive Award and does not address
special rules that may be applicable to directors, officers and greater-than-10%
shareholders of the Company.

     OPTIONS.  There will not be any federal income tax consequences to either
the Participant or the Company as a result of the grant to a Participant of an
Option under the 1991 Plan.  The exercise by a Participant of an Incentive
Option will also not result in any federal income tax consequences to the
Company or the Participant, except that an amount equal to the excess of the
fair market value of the shares acquired upon exercise of the Incentive Option,
determined at the time of exercise, over the consideration paid for the shares
by the Participant will be a tax preference item for purposes of the alternative
minimum tax.  Upon exercise of Non-Statutory Option, a Participant will
recognize ordinary income on the date of exercise in an amount equal to the
difference between the fair market value of the shares purchased and the
consideration paid for the shares.  In general, the Company will be entitled to
a compensation expense deduction in connection with the exercise of a 
Non-Statutory Option for any amounts includable in the taxable income of a
Participant as ordinary income.

     At the time of the subsequent sale or disposition of the shares obtained
upon the exercise of a Non-Statutory Option, any gain or loss will be a capital
gain or loss.  Whether the gain or loss constitutes long or short term capital
gain or loss will depend upon the length of time the Participant held the stock
prior to its disposition.  Participants should consult their tax advisors to
determine whether any specific gain or loss constitutes long or short term
capital gain or loss.  

     If a Participant disposes of the shares acquired upon exercise of an
Incentive Option, the federal income tax consequences will depend upon how long
the Participant has held the shares.  If the Participant does not dispose of the
shares within two years after the Incentive Option was granted, nor within one
year after the Participant exercised the Incentive Option and the shares were
transferred to the Participant, then the Participant will recognize a capital
gain or loss.  The amount of the long-term capital gain or loss will be equal to
the difference between (i) the amount the Participant realized on disposition of
the shares, and (ii) the option price at which the Participant acquired the
shares.  Whether the gain or loss constitutes long or short term capital gain or
loss will depend upon the length of time the Participant held the stock prior to
its disposition.  Participants should consult their tax advisors to determine
whether any specific gain or loss constitutes long or short term capital gain or
loss.  The Company is not entitled to any compensation expense deduction under
these circumstances.

     If the Participant does not satisfy both of the above holding period
requirements, then the Participant will be required to report as ordinary
income, in the year the Participant disposes of the shares, the amount by which
the lesser of the fair market value of the shares at the time of exercise of the
Incentive Option or the amount realized on the disposition of the shares (if the
disposition is the result of a sale or exchange to one other than a related
taxpayer) exceed the option price for the shares.  The Company will be entitled
to a compensation expense deduction in an amount equal to the ordinary income
includable in the taxable income of the Participant.  The Company may be
required to withhold in order to receive a deduction.  The remainder of the gain
or loss recognized on the disposition, if any, will be treated as long-term or
short-term capital gain or loss, depending on the holding period.

     RESTRICTED STOCK AWARDS AND STOCK BONUSES.  With respect to shares issued
pursuant to a Restricted Stock Award that is not subject to a substantial risk
of forfeiture or with respect to Stock Bonuses, a Participant must include as
ordinary income in the year of receipt an amount equal to the fair market value
of the shares received on the date of receipt.  With respect to shares that are
subject to a substantial risk of forfeiture, a Participant may file an election
under Section 83(b) of the Code within 30 days after receipt to include as
ordinary income in the year of receipt an amount equal to the fair market 

                                       18
<PAGE>

value of the shares received on the date of receipt (determined as if the 
shares were not subject to any risk of forfeiture).  If a Section 83(b) 
election is made, the Participant will not recognize any additional income 
when the restrictions on the shares issued in connection with the Restricted 
Stock Award lapse.  The Company will receive a corresponding tax deduction 
for any amounts includable in the taxable income of a Participant as ordinary 
income.

     A Participant who does not make a Section 83(b) election within 30 days of
the receipt of a Restricted Stock Award that is subject to a substantial risk of
forfeiture will recognize ordinary income at the time of the lapse of the
restrictions in an amount equal to the then fair market value of the shares
freed of restrictions.  The Company will receive a corresponding tax deduction
for any amounts includable in the taxable income of a Participant as ordinary
income.

     EXCISE TAX ON PARACHUTE PAYMENTS.  The Code imposes a 20% excise tax on the
recipient of "excess parachute payments," as defined in the Code, and denies tax
deductibility to the Company for such excess parachute payments.  Generally,
parachute payments are payments in the nature of compensation to employees of a
company who are officers, shareholders or highly compensated employees, which
payments are contingent upon a change in control of a company.  Acceleration of
the vesting of Incentive Awards upon a change in control of the Company may
constitute parachute payments and, in certain cases, "excess parachute
payments."

AWARDS UNDER THE 1991 PLAN

     As of December 31, 1997, the Company has granted Options to purchase shares
of Common Stock under the 1991 Plan as follows:  Mr. Badolato, 50,000 shares;
Mr. Melsen, 130,000 shares; Mr. Seck, 30,000 shares; Mr. Haworth, 115,000
shares; all executive officers of the Company as a group, 325,000 shares; all
non-executive directors of the Company as a group, 55,500 shares; and 
non-executive employees of the Company as a group, 699,500 shares. The foregoing
amounts include grants of Non-Statutory Options on December 11, 1997 to each of
Messrs. Stassen, Strickland, Wright and Badolato subject to shareholder approval
at the Annual Meeting of the proposal to increase the number of shares reserved
for issuance under the 1991 Plan.  Accordingly, Messrs. Stassen, Strickland,
Wright and Badolato will benefit from the approval of the proposal to increase
the number of shares reserved for issuance under the 1991 Plan.  Neither the
number or types of any future Incentive Awards to be received by or allocated to
any other particular participant or group of participants under the 1991 Plan is
presently determinable.  See "New Plan Benefits" below.  

RECOMMENDATION

     The Board of Directors recommends a vote FOR the approval and ratification
of the proposal to increase the number of shares reserved under the 1991 Stock
Incentive Plan.  The affirmative vote of a majority of the shares of Common
Stock present in person or proxy at the Annual Meeting, and, at least a majority
of the minimum number of votes necessary for a quorum to transact business at
the Annual Meeting, is necessary for approval.  Unless a contrary choice is
specified, proxies solicited by the Board of Directors will be voted FOR
approval.

                 PROPOSAL TO AMEND THE EMPLOYEE STOCK PURCHASE PLAN

INTRODUCTION

     The Purchase Plan was first adopted by the Board of Directors of the
Company in June of 1992 and approved by the shareholders of the Company in May
of 1993.  The Purchase Plan provides for the purchase of Common Stock by
eligible employees of the Company and its subsidiaries through payroll
deductions.  Under the Purchase Plan, as amended, the Company conducts a series
of offerings (each, an "Offering") of its Common Stock, each continuing for
three months and each beginning on January 1, April 1, July 1 and October 1 of
each year (the "Offering Date"), and ending on March 31, June 30, September 30
and December 31 of each year (the "Offering Period").  On each Offering Date,
each eligible participating employee ("Participant") in the Purchase Plan is
granted, by operation of the Purchase Plan, an option (a "Purchase Option") to
purchase as many full shares of Common Stock as can be purchased with payroll
deductions authorized by the Participant and credited to the Participant's
account during the Offering beginning on that Offering Date.  

     On May 14, 1997, the Board amended the Purchase Plan, subject to
shareholder approval, to increase the number of shares of Common Stock reserved
for issuance under the Purchase Plan by 25,000 shares, from 100,000 shares to
125,000 shares.  On December 11, 1997, the Board again amended the Purchase
Plan, subject to shareholder approval, to increase the number of shares of
Common Stock reserved for issuance under the Purchase Plan by another 100,000
shares, from 125,000 shares to 225,000 shares.  The Company's shareholders are
being asked to approve these increases as a combined amendment at the Annual
Meeting.  In the event that the amendment is not approved at the Annual Meeting,
any shares issued and sold in excess of the shares currently reserved for
issuance under the Purchase Plan in reliance on these amendments will be deemed
to have been issued pursuant to the grant and exercise of non-plan options.

REASONS FOR AMENDMENT

     The increase in the aggregate number of shares of Common Stock reserved for
issuance under the Purchase Plan from 100,000 shares to 225,000 shares is
necessary to permit the Company to continue the operation of the Purchase Plan
for the benefit of new participants, as well as to allow continued participation
by existing participants under the Purchase Plan.  As of December 31, 1997,
Purchase Options to purchase an aggregate of 117,221 shares have been exercised
under the Purchase Plan.  As indicated above, if these amendments are not
approved at the Annual Meeting, the Company will make a pro rata allocation of
the shares of Common Stock remaining available for issuance under the Purchase
Plan prior to the amendments in as uniform and equitable a manner as is
practicable and any shares issued and sold in excess of the shares currently
reserved for issuance under the Purchase Plan in reliance on these amendments
will be deemed to have been issued pursuant to the grant and exercise of 
non-plan options.  See "Federal Income Tax Consequences -- Non-Plan Options," 
below.

SUMMARY OF THE PURCHASE PLAN

     A general description of the basic features of the Purchase Plan is
outlined below.  This summary is qualified in its entirety by the terms of the
Purchase Plan.  The Company will furnish without charge a copy of the Purchase
Plan to any shareholder of the Company as of March 13, 1998, upon receipt from
any such person of an oral or written request for the Purchase Plan.  Such
request should be sent to the Company at AVECOR Cardiovascular Inc., 7611
Northland Drive, Minneapolis, Minnesota  55428, Attn:  Shareholder Relations, or
made by telephone at (612) 391-9000.

                                       20
<PAGE>

     GENERAL.  The purpose of the Purchase Plan is to advance the interests of
the Company and its shareholders by providing employees of the Company and its
subsidiaries with an opportunity to acquire an ownership interest in the Company
through the purchase of shares of Common Stock of the Company on favorable terms
through payroll deduction.

     With respect to an Offering, any employee who has been employed
continuously by the Company or a subsidiary for at least one year prior to the
Offering Date of the Offering will be eligible to participate in that Offering. 
The maximum number of shares currently reserved for sale under the Purchase
Plan, as amended, is 225,000 shares of Common Stock, subject to adjustments as
provided in the Purchase Plan.  If the total number of shares which would
otherwise be subject to Purchase Options granted on an Offering Date exceeds the
number of shares then available under the Purchase Plan (after deduction of all
shares for which Purchase Options have been exercised or are then outstanding),
the Company will make a pro rata allocation of the shares remaining available
for Purchase Option grants in as uniform and equitable a manner as is
practicable.  If this occurs, the Company will give written notice of such
reduction of the number of shares subject to the Purchase Option to each
affected Participant and will return any excess funds accumulated in each
Participant's account as soon as practicable after the termination date of such
Offering.  The number and type of shares of Common Stock subject to outstanding
Purchase Options, and the exercise price of outstanding Purchase Options, will
be appropriately adjusted if any Purchase Option is exercised after any Common
Stock dividend, split-up, recapitalization, merger, consolidation, combination
or exchange of Common Stock or the like.  The Purchase Plan is currently
administered by the Compensation Committee of Board of Directors.

     PARTICIPATION.  An eligible employee may become a Participant in the
Purchase Plan by completing a subscription agreement authorizing payroll
deduction on the form provided by the Company and filing it with the Company's
payroll office not less than 15 days before the Offering Date of the first
Offering in which the Participant wishes to participate.  Payroll deductions for
a Participant will begin with the first payroll following the applicable
Offering Date and continue until the termination date of the Purchase Plan,
subject to termination by the Participant at any time.  An otherwise eligible
employee will not be allowed to participate in the Purchase Plan if the employee
would, as of an Offering Date, own 5% or more of the outstanding Common Stock or
if the rate at which the employee has elected to have payroll deductions
withheld under the Purchase Plan would permit the employee to purchase shares of
Common Stock with a fair market value of more than $25,000 (determined as of the
Offering Date).  On March 13, 1998, approximately 214 persons are eligible to
participate in the Purchase Plan.

     PAYROLL DEDUCTIONS.  By filing a subscription agreement, a Participant
elects to have payroll deductions made on each payday during the Offering Period
at a rate equal to a whole percentage from 1% to 10% (but in no event less than
$25.00) of the compensation which he or she would have received on the payday. 
No increases or decreases in the amount of payroll deductions for a Participant
may be made during an Offering Period.  A Participant may increase or decrease
the rate of the Participant's payroll deductions to a whole percentage from 1%
to 10% (but in no event less than $25.00) as of the beginning of a subsequent
Offering Period by completing a new authorization for payroll deduction at least
15 days prior to the Offering Date for which the increase or decrease is to
become effective.  A Participant may discontinue participation in the Purchase
Plan as described below under the heading "Withdrawal and Termination of
Employment."

     The funds accumulated through a Participant's payroll deductions under the
Purchase Plan are held by the Company in an account established under the
Purchase Plan for the Participant.  These funds are held by the Company as part
of its general assets, usable for any corporate purpose, and the Company 

                                       21
<PAGE>

is not obligated to keep these funds separate from its other corporate funds. 
Participants will not receive any interest from the Company for the funds 
accumulated from their payroll deductions under the Purchase Plan.

     PURCHASE OF SHARES.  On each Offering Date each Participant is granted, by
operation of the Purchase Plan, a Purchase Option for the number of full shares
of the Company's Common Stock that he or she will be able to purchase with the
payroll deductions accumulated during the Offering Period and the balance (if
any) carried forward from the Participant's payroll deduction account from the
preceding Offering Period.  Unless a Participant gives written notice as
specified in the Purchase Plan or withdraws from the Purchase Plan, the
Participant's Purchase Option will be exercised automatically on the last day of
the Offering Period for the number of full shares of Common Stock that the
accumulated payroll deductions in the Participant's account on the last day of
the Offering Period will purchase at the applicable price.  Any cash remaining
in a Participant's account under the Purchase Plan after a purchase by the
Participant of shares at the termination of each Offering Period which is
insufficient to purchase a full share of Common Stock will be carried forward
into the Participant's payroll deduction account for the following Offering
Period.

     The per share purchase price of the shares offered in a given Offering is
the lower of 85% of the fair market value of a share of the Common Stock of the
Company on the first trading day or last trading day of the Offering Period. 
Fair market value of the Common Stock is the average of the high and low prices
of the Common Stock, as reported by the Nasdaq National Market on the applicable
date.  On March 13, 1998, the last sale price of the Common Stock as reported by
Nasdaq National Market was $7.125.

     The Company will deliver to each Participant, as soon as practicable after
the last day of the Offering Period, a certificate representing the shares of
Common Stock purchased upon exercise of the Purchase Option granted for such
Offering Period.  No Participant will have any interest in any Common Stock
subject to a Purchase Option until the Purchase Option has been exercised, at
which point the interest will be strictly that of a purchaser of the shares of
Common Stock purchased upon such exercise, pending delivery of such shares
pursuant to the Purchase Plan.

     NON-TRANSFERABILITY OF PURCHASE OPTIONS.  Neither payroll deductions
credited to a Participant's account nor any rights with regard to the exercise
of a Purchase Option or to receive shares of Common Stock under the Purchase
Plan may be assigned, transferred, pledged or otherwise disposed of in any way
(other than by will, the laws of descent and distribution, or by designation of
a beneficiary).  Any such attempt at assignment, transfer, pledge or other
disposition will have no effect, except that the Company may treat such act as
an election to withdraw funds, in which case the provisions described below
under the heading "Withdrawal and Termination of Employment" will apply.

     WITHDRAWAL AND TERMINATION OF EMPLOYMENT.  A Participant may terminate
participation in the Purchase Plan and withdraw all, but not less than all, of
the payroll deductions credited to the Participant's account under the Purchase
Plan at any time prior to the last day of an Offering Period by giving written
notice to the Company.  The notice must state the Participant's desire to
terminate involvement in the Purchase Plan, specify a termination date and
request the withdrawal of all of the Participant's payroll deductions held under
the Purchase Plan.  All of the Participant's payroll deductions credited to the
Participant's account will be paid to such Participant as soon as practicable
after the termination date specified in the notice or after receipt of notice of
withdrawal, the Purchase Option for the current Offering Period will
automatically be canceled and no further payroll deductions for the purchase of
shares will be made during the Offering Period or for any subsequent Offering
Period unless 

                                       22
<PAGE>

a new participation form is filed.  A Participant's withdrawal from an 
Offering will not have any effect upon the Participant's eligibility to 
participate in a succeeding Offering or in any similar plan which the Company 
may adopt, except that a Participant who is an officer or director may not 
participate in the Purchase Plan for at least six months after the effective 
date of such termination and withdrawal unless otherwise permitted by the 
Committee in its sole discretion.

     Upon termination of the Participant's employment prior to the last day of
an Offering Period for any reason, including retirement or death, the payroll
deductions credited to such Participant's account will be returned to such
Participant or, in the case of the Participant's death, to the person or persons
entitled to such funds in accordance with the provisions described above under
the section "Non-Transferability of Purchase Options" and the Participant's
Purchase Option will be automatically canceled.  A transfer of employment
between the Company and a subsidiary or between subsidiaries and absences or
leaves approved by the Company are not considered terminations under the
Purchase Plan.

FEDERAL INCOME TAX CONSEQUENCES.  

     The following general description of federal income tax consequences is
based upon current statutes, regulations and interpretations.  This description
is not intended to address specific tax consequences applicable to an individual
participant who receives a Purchase Option and does not address special rules
that may be applicable to directors, officers and greater-than-10% shareholders
of the Company.

     The Purchase Plan is intended to qualify as an "employee stock purchase
plan" under Section 423 of the Code.  If the Purchase Plan so qualifies, the
amount withheld from a Participant's compensation under the Purchase Plan will
constitute ordinary income for federal income tax purposes in the year in which
such amounts would otherwise have been paid to the Participant.  However, a
Participant will generally not recognize any income for federal income tax
purposes either on the grant of a Purchase Option or upon the issuance of any
shares of Common Stock under the Purchase Plan.

     The federal income tax consequences incurred upon disposition of shares of
Common Stock acquired under the Purchase Plan depend upon how long a Participant
holds the shares.  If a Participant disposes of shares acquired under the
Purchase Plan (other than a transfer by reason of death) within a period of two
years from the Offering Date of the Offering in which the shares were acquired,
an amount equal to the difference between the purchase price and the fair market
value of the shares on the last day of the Offering Period will be treated as
ordinary income for federal income tax purposes in the taxable year in which the
disposition takes place.  Such amount may be subject to wage withholding.  The
difference between the amount realized upon such disposition of the shares and
their fair market value on the last day of the Offering Period will constitute
capital gain or loss.  Whether the gain or loss constitutes long or short term
capital gain or loss will depend upon the length of time the Participant held
the stock prior to its disposition.  Participants should consult their tax
advisors to determine whether any specific gain or loss constitutes long or
short term capital gain or loss.

     If a Participant disposes of any shares acquired under the Purchase Plan
more than two years after the Offering Date of the Offering in which such shares
were acquired (or if no disposition has occurred by the time of Participant's
death) an amount equal to the lesser of (a) the excess of the fair market value
of the shares at the time of disposition (or death) over the purchase price, or
(b) the excess of the fair market value of the shares on the Offering Date of
the Offering in which the shares were acquired over the purchase price will be
recognized as ordinary income and may be subject to wage withholding.  With
respect to a disposition of such shares, any remaining gain on such disposition
will be taxed as long-term 

                                       23
<PAGE>

capital gain.  With respect to a transfer of such shares upon death, any 
remaining gain or loss will not be recognized.  However, a subsequent sale or 
exchange of such shares by a Participant's estate or the person receiving 
such shares by reason of the Participant's death may result in capital gain 
or loss.

     No income tax deduction ordinarily is allowed to the Company with respect
to the grant of any Option, the issuance of any shares of Common Stock under the
Purchase Plan or the disposition of any shares acquired under the Purchase Plan
and held for two years.  However, if a Participant disposes of shares purchased
under the Purchase Plan within two years after the Offering Date of the Offering
in which the shares were acquired, the Company will receive an income tax
deduction in the year of such disposition in an amount equal to the amount
constituting ordinary income to the Participant, provided that the Company
complies with the applicable wage withholding requirements.

     NON-PLAN OPTIONS.  In the event the amendments to the Purchase Plan are not
approved, any shares issued and sold in excess of the shares currently reserved
for issuance under the Purchase Plan in reliance on the amendments will be
deemed to have been issued pursuant to the grant and exercise of non-plan
options ("Non-Plan Options").  Upon exercise of a Non-Plan Option, the
Participant will generally recognize ordinary income in an amount equal to the
difference between (i) the fair market value of the shares purchased, determined
on the date of exercise, and (ii) the amount paid for the shares.  Amounts
taxable to the Participant as ordinary income are deductible in the same year by
the Company, provided that the Company complies with the applicable income tax
withholding provisions.  When the Participant disposes of shares acquired by the
exercise of a Non-Plan Option, the difference between the amount received and
the fair market value of the shares on the date of exercise will be treated as
capital gain or loss depending on the length of time the shares were held. 
Whether the gain or loss constitutes long or short term capital gain or loss
will depend upon the length of time the Participant held the stock prior to its
disposition.  Participants should consult their tax advisors to determine
whether any specific gain or loss constitutes long or short term capital gain or
loss.  For purposes of determining the holding period for the shares, the shares
are treated as acquired on the date of exercise.  For exceptions to these
general rules, see the discussion below under "Excise Tax on Parachute
Payments."

     EXCISE TAX ON PARACHUTE PAYMENTS.  The Code imposes a 20% excise tax on the
recipient of "excess parachute payments," as defined in the Code, and denies tax
deductibility to the Company for such excess parachute payments.  Generally,
parachute payments are payments in the nature of compensation to employees of a
company who are officers, shareholders or highly compensated employees, which
payments are contingent upon a change in control of a company.  Acceleration of
the vesting of Non-Plan Options upon a change in control of the Company may
constitute parachute payments and, in certain cases, "excess parachute
payments."

PURCHASES UNDER THE PURCHASE PLAN

     As of December 31, 1997, shares of Common Stock have been purchased under
the Purchase Plan as follows:  Mr. Badolato, none; Mr. Melsen, 1,407 shares; Mr.
Seck, none; Mr. Haworth, 2,104 shares; all executive officers of the Company as
a group, 3,511 shares; and non-executive employees of the Company as a group,
113,710 shares.  Non-executive directors of the Company are not eligible to
participate in the Purchase Plan.  Messrs. Melsen and Haworth purchased shares
of Common Stock under the Purchase Plan in reliance on the amendments to the
Purchase Plan to increase the aggregate number of shares of Common Stock
reserved for issuance under the Purchase Plan.  In the event that these
amendments are not approved at the Annual Meeting, the Company shall make a pro
rata allocation of the shares of Common Stock remaining available for issuance
under the Purchase Plan prior to the amendments in as uniform and equitable a
manner as is practicable and any shares issued and sold in 

                                       24
<PAGE>

excess of the shares reserved for issuance under the Purchase Plan prior to 
the amendments in reliance on these amendments will be deemed to have been 
issued pursuant to the grant and exercise of non-plan options.  See "Proposal 
to Amend the Employee Stock Purchase Plan -- Federal Income Tax Consequences 
- -- Non-Plan Options." Accordingly, Messrs. Melsen and Haworth will benefit 
from the approval at the Annual Meeting of the proposal to increase the 
number of shares reserved for issuance under the Purchase Plan.  The number 
of shares underlying Purchase Options to be granted in any future Offering to 
any other particular participant or group of participants under the Purchase 
Plan is not presently determinable. See "New Plan Benefits" below.

RECOMMENDATION

     The Board of Directors recommends a vote FOR the approval and ratification
of the proposal to increase the number of shares reserved under the Employee
Stock Purchase Plan.  The affirmative vote of a majority of the shares of Common
Stock present in person or proxy at the Annual Meeting, and, at least a majority
of the minimum number of votes necessary for a quorum to transact business at
the Annual Meeting, is necessary for approval.  Unless a contrary choice is
specified, proxies solicited by the Board of Directors will be voted FOR
approval.

     Prior to the Annual Meeting, the Board of Directors anticipates approving
the selection of Coopers & Lybrand L.L.P. as independent accountants to make an

Company does not intend to request that the shareholders approve the selection
of the independent public accountants for the fiscal year ended December 31,
1998.  The Company has requested and expects a representative of Coopers &
Lybrand L.L.P. to be present at the Annual Meeting to make a statement if he or
she so desires and to respond to appropriate questions.


              SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING  COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's directors and executive officers, and persons who own more than
10% of the Company's Common Stock, to file with the Securities and Exchange
Commission (the "SEC") initial reports of ownership and reports of changes in
ownership of Common Stock and other equity securities of the Company.  Executive
officers, directors and greater-than-10% shareholders are required by SEC
regulations to furnish the Company with copies of all Section 16(a) reports they
file.  To the Company's knowledge, based solely on review of the copies of such
reports furnished to the Company for the period ended December 31, 1997, all
Section 16(a) reports required to be filed by the Company's executive officers,
directors and greater-than-10% shareholders were filed on a timely basis except
for a report on Form 4 not filed on a timely basis by Mr. Stassen to report Mr.
Stassen's exercise of options to purchase 10,500 shares of Common Stock.

                                PLAN ADMINISTRATION.

3.1    THE COMMITTEE.  The Plan shall be administered by the Board or by a
committee of the Board consisting of not less than three persons; provided,
however, that from and after the date on which the Company first registers a
class of its equity securities under Section 12 of the Exchange Act, the Plan

of such a committee shall constitute a quorum.  Such a committee shall act by

taken without a meeting if unanimous written consent is given.  Copies of
minutes of such a committee's meetings and of its actions by written consent
shall be provided to the Board and kept with the corporate records of the
Company.  As used in this Plan, the term "Committee" will refer to the Board or

3.2    AUTHORITY OF THE COMMITTEE.  

3.2.1  In accordance with and subject to the provisions of the Plan, the
Committee shall have the authority to determine the following: (i) the Eligible
Recipients who shall be selected as Participants, (ii) the nature and extent of
the Incentive Awards to be made to each Participant (including the number of
shares of Common Stock to be subject to each Incentive Award, any exercise price
and the manner in which Incentive Awards will vest or become exercisable), (iii)
the time or times when Incentive Awards will be granted, (iv) the duration of
each Incentive Award, (v) the restrictions and other conditions to which the
payment or vesting of Incentive Awards may be subject, and (vi) such other
provisions of the 

                                       3
<PAGE>


Incentive Awards as the Committee may deem necessary or desirable and as 
consistent with the terms of the Plan.  The Committee shall determine the 
form or forms of the agreements with Participants which shall evidence the 
particular terms, conditions, rights and duties of the Company and the 
Participants with respect to Incentive Awards granted pursuant to the Plan, 
which agreements shall be consistent with the provisions of the Plan.

3.2.2  With the consent of the Participant affected thereby, the Committee may
amend or modify the terms of any outstanding Incentive Award in any manner,
provided that the amended or modified terms are permitted by the Plan as then in
effect.  Without limiting the generality of the foregoing sentence, the
Committee may, with the consent of the Participant affected thereby, modify the
exercise price, number of shares or other terms and conditions of an Incentive
Award, extend the term of an Incentive Award, accelerate the exerciseability or
vesting or otherwise terminate any restrictions relating to an Incentive Award,
accept the surrender of any outstanding Incentive Award, or, to the extent not
previously exercised or vested, authorize the grant of new Incentive Awards in
substitution for surrendered Incentive Awards.

3.2.3  With respect to the Company or any other entity whose performance is
relevant to the grant or vesting of an Incentive Award, in the event of (i) any
reorganization, merger, consolidation, recapitalization, liquidation,
reclassification, stock dividend, stock split, combination of shares, rights
offering or divestiture (including a spin-off) or any other change in corporate
structure or shares, (ii) any purchase, acquisition, sale or disposition of a
significant amount of assets or a significant business, any extraordinary
dividend or any other similar transaction, (iii) any change in accounting
principles or practices, or (iv) any other significant change in financial
condition, the Committee (or, if the Company is not the surviving corporation in
any such transaction, the board of directors of the surviving corporation) may,
without the consent of the Participant affected thereby, amend or modify the
vesting criteria of any outstanding Incentive Award that is based in whole or in
part on the financial performance of the Company or such other entity so as
equitably to reflect such event, with desired result that the criteria for
evaluating such financial performance of the Company or such other entity shall
be substantially the same (in the sole discretion of the Committee or the board
of directors of the surviving corporation) following such event as prior to such
event; provided, however, that the amended or modified terms are permitted by
the Plan as then in effect.

3.2.4  The Committee shall have the authority, subject to the provisions of the
Plan, to establish, adopt and revise such rules and regulations relating to the
Plan as it may deem necessary or advisable for the administration of the Plan. 
The Committee's decisions and determinations under the Plan need not be uniform
and may be made selectively among Participants, whether or not such Participants
are similarly situated.  Each determination, interpretation or other action made
or taken by the Committee pursuant to the provisions of the Plan shall be
conclusive and binding for all purposes and on all persons, including, without
limitation, the Company and its Subsidiaries, the shareholders of the Company,
the Committee and each of its members, the directors, officers and employees of
the Company and its Subsidiaries, and the Participants and their respective
successors in interest.  No member of the Committee shall be liable for any
action or determination made in good faith with respect to the Plan or any
Incentive Award granted under the Plan.

                             STOCK SUBJECT TO THE PLAN.

4.1    NUMBER OF SHARES.  Subject to adjustment as provided in Section 4.3 of
the Plan, the maximum number of shares of Common Stock that shall be reserved
for issuance under the Plan shall be 1,500,000 shares of Common Stock.  The
maximum number of shares authorized and reserved may be increased from time to
time by approval of the Board and, if required pursuant to Rule 16b-3 under the
Exchange Act, Section 422 of the Code, or the rules of any securities exchange
or the NASD, the shareholders of the Company.

4.2    SHARES AVAILABLE FOR USE.  Shares of Common Stock that may be issued
upon exercise of Options or that are issued as Restricted Stock Awards shall be
applied to reduce the maximum number of shares of Common Stock remaining
available for use under the Plan.  Any shares of Common Stock that are subject
to an Option (or any portion thereof) that lapses, expires or for any reason is
terminated unexercised shall automatically again become available for use under
the Plan.  Any shares of Common Stock that constitute the forfeited portion of a
Restricted Stock Award, however, shall not become available for further use
under the Plan.

4.3    ADJUSTMENTS TO SHARES.  In the event of any reorganization, merger,
consolidation, recapitalization, liquidation, reclassification, stock dividend,
stock split, combination of shares, rights offering, extraordinary dividend
(including a spin-off) or any other change in the corporate structure or shares
of the Company, the Committee (or, if the Company is not the surviving
corporation in any such transaction, the board of directors of the surviving
corporation) shall make appropriate adjustment (which determination shall be
conclusive) as to the number and kind of securities subject to and reserved
under the Plan and, in order to prevent dilution or enlargement of the rights of
Participants, the number, kind and, where applicable, exercise price of
securities subject to outstanding Incentive Awards.  Without limiting the
generality of the foregoing, in the event that any of such transactions are
effected in such a way that the holder of Common Stock shall be entitled to
receive stock, securities or assets, including cash, with respect to or in
exchange for such Common Stock, all Participants holding outstanding Options
shall upon the exercise of such Options receive, in lieu of any shares of Common
Stock that they may be entitled to receive, such stock, securities or assets,
including cash, as would have been issued to such Participants if their Options
had been exercised and such Participants had received Common Stock prior to such
transaction.

                                   PARTICIPATION.

       Participants in the Plan shall be those Eligible Recipients who, in the
judgment of the Committee, have performed, are performing, or during the term of
an Incentive Award will perform, services in the management, operation and
development of the Company or any Subsidiary, and significantly contributed, are
significantly contributing or are expected to significantly contribute to the
achievement of corporate economic objectives.  Eligible Recipients may be
granted from time to time one or more Incentive Awards, as may be determined by
the Committee in its sole discretion.  The number, type, terms and conditions of
Incentive Awards granted to various Eligible Recipients need not be uniform,
consistent or in accordance with any plan, regardless of whether such Eligible
Recipients are similarly situated.  Upon determination by the Committee that an
Incentive Award is to be granted to an Eligible Recipient, written notice shall
be given such person, specifying the terms, conditions, rights and 

                                       5
<PAGE>

duties related thereto.  Each Eligible Recipient to whom an Incentive Award 
is to be granted shall enter into an agreement with the Company, in such form 
as the Committee shall determine and which is consistent with the provisions 
of the Plan, specifying such terms, conditions, rights and duties.  Incentive 
Awards shall be deemed to be granted as of the date specified in the grant 
resolution of the Committee, which date shall be the date of the related 
agreement with the Participant.

                                   STOCK OPTIONS.

6.1    GRANT.  An Eligible Recipient may be granted one or more Options under
the Plan, and such Options shall be subject to such terms and conditions,
consistent with the other provisions of the Plan, as shall be determined by the
Committee in its sole discretion.  The Committee may designate whether an Option
is to be considered an Incentive Stock Option or a Non-Statutory Stock Option;
provided, however, that an Incentive Stock Option shall be granted only to an
Eligible Recipient who is an employee of the Company or a Subsidiary.  The terms
of the agreement relating to a Non-Statutory Stock Option shall expressly
provide that such Option shall not be treated as an Incentive Stock Option.

6.2    EXERCISE.  An Option shall become exercisable at such times and in such
installments (which may be cumulative) as shall be determined by the Committee
in its sole discretion at the time the Option is granted.  Upon the completion
of its exercise period, an Option, to the extent not then exercised, shall
expire.

6.3    Exercise Price.  

6.3.1  INCENTIVE STOCK OPTIONS.  The per share price to be paid by the
Participant at the time an Incentive Stock Option is exercised shall be
determined by the Committee, in its discretion, at the date of its grant;
provided, however, that such price shall not be less than (i) 100% of the Fair
Market Value of one share of Common Stock on the date the Option is granted, or
(ii) 110% of the Fair Market Value of one share of Common Stock on the date the
Option is granted if, at the time the Option is granted, the Participant owns,
directly or indirectly (as determined pursuant to Section 424(d) of the Code),
more than 10% of the total combined voting power of all classes of stock of the
Company, any subsidiary corporation or any parent corporation of the Company
(within the meaning of Sections 424(f) and 424(e), respectively, of the Code).

6.3.2  NON-STATUTORY STOCK OPTIONS.  The per share price to be paid by the
Participant at the time a Non-Statutory Stock Option is exercised shall be
determined by the Committee in its sole discretion at the time the Option is
granted, but shall not be less than 85% of the Fair Market Value of one share of
Common Stock on the date the Option is granted.

6.4    DURATION.

6.4.1  INCENTIVE STOCK OPTIONS.  The period during which an Incentive Stock
Option may be exercised shall be fixed by the Committee in its sole discretion
at the time such Option is granted; provided, however, that in no event shall
such period exceed 10 years from its date of grant or, in the case of a
Participant who owns, directly or indirectly (as determined pursuant to Section
424(d) of the Code), more than 10% of the total combined voting power of all
classes of stock of the Company, any subsidiary corporation or any parent
corporation of the Company (within the meaning of Sections 424(f) and 424(e),
respectively, of the Code), five years from its date of grant.

6.4.2  NON-STATUTORY STOCK OPTION.  The period during which a Non-Statutory
Stock Option may be exercised shall be fixed by the Committee in its sole
discretion at its date of grant.

6.4.3  EFFECT OF TERMINATION OF EMPLOYMENT.  Notwithstanding the foregoing,
except as provided in Articles 10 and 12 of the Plan, all Options granted to a
Participant shall terminate and may no longer be exercised if the Participant's
employment with the Company and all Subsidiaries ceases.

6.5    MANNER OF OPTION EXERCISE.  An Option may be exercised by a Participant
in whole or in part from time to time, subject to the conditions contained
herein and in the agreement evidencing such Option, by delivery, in person or
through certified or registered mail, of written notice of exercise to the
Company at its principal executive office in Minneapolis, Minnesota (Attention:
Treasurer), and by paying in full the total Option exercise price for the shares
of Common Stock purchased.  Such notice shall be in a form satisfactory to the
Committee and shall specify the particular Option (or portion thereof) that is
being exercised and the number of shares with respect to which the Option is
being exercised.  Subject to compliance with Section 14.1 of the Plan, the
exercise of the Option shall be deemed effective upon receipt of such notice and
payment complying with the terms of the Plan and the agreement evidencing such
Option.  As soon as practicable after the effective exercise of the Option, the
Participant shall be recorded on the stock transfer books of the Company as the
owner of the shares purchased, and the Company shall deliver to the Participant
one or more duly issued stock certificates evidencing such ownership.  If a
Participant exercises any Option with respect to some, but not all, of the
shares of Common Stock subject to such Option, the right to exercise such Option
with respect to the remaining shares shall continue until it expires or
terminates in accordance with its terms.  An Option shall only be exercisable
with respect to whole shares.

6.6    PAYMENT OF EXERCISE PRICE.

6.6.1  The total purchase price of the shares to be purchased upon exercise of
an Option shall be paid entirely in cash (including check, bank draft or money
order); provided, however, that the Committee, in its sole discretion, may allow
such payments to be made, in whole or in part, by delivery of a Broker Exercise
Notice or a promissory note (containing such terms and conditions as the
Committee may in its discretion determine), by transfer from the Participant to
the Company of Previously Acquired Shares, or by a combination thereof.  In
determining whether or upon what terms and conditions a Participant will be
permitted to pay the purchase price of an Option in a form other than cash, the
Committee may consider all relevant facts and circumstances, including, without
limitation, the tax and securities law consequences to the Participant and the
Company and the financial accounting consequences to the Company.  In the event
the Participant is permitted to pay the total purchase price of an Option in
whole or in part with Previously Acquired Shares, the value of such shares shall
be equal to their Fair Market Value on the date of exercise of the Option.

6.6.2  For purposes of this Section 6.6, a "Broker Exercise Notice" shall mean
a written notice from a Participant to the Company at its principal executive
office in Minneapolis, Minnesota (Attention: Treasurer), made on a form and in
the manner as the Committee may from time to time determine, pursuant to which
the Participant irrevocably elects to exercise all or any portion of an Option
and irrevocably directs the Company to deliver the Participant's stock
certificates to be issued to such Participant upon such Option exercise directly
to a broker or dealer.  A Broker Exercise Notice must be accompanied by or
contain irrevocable instructions to the broker or dealer (i) to promptly sell a
sufficient number of shares of such Common Stock or to loan the Participant a
sufficient amount of money to pay the exercise price for the Options and, if not
otherwise satisfied by the Participant, to fund any related 

                                       7
<PAGE>

employment and withholding tax obligations due upon such exercise, and (ii) 
to promptly remit such sums to the Company upon the broker's or dealer's 
receipt of the stock certificates.

6.7    RIGHTS AS A SHAREHOLDER.  The Participant shall have no rights as a
shareholder with respect to any shares of Common Stock covered by an Option
until the Participant shall have become the holder of record of such shares, and
no adjustments shall be made for dividends or other distributions or other
rights as to which there is a record date preceding the date the Participant
becomes the holder of record of such shares, except as the Committee may
determine pursuant to Section 4.3 of the Plan. 

6.8    DISPOSITION OF COMMON STOCK ACQUIRED PURSUANT TO THE EXERCISE OF
INCENTIVE STOCK OPTIONS.  Prior to making a disposition (as defined in Section
424(c) of the Code) of any shares of Common Stock acquired pursuant to the
exercise of an Incentive Stock Option granted under the Plan before the
expiration of two years after its date of grant or before the expiration of one
year after its date of exercise and the date on which such shares of Common
Stock were transferred to the Participant pursuant to exercise of the Option,
the Participant shall send written notice to the Company of the proposed date of
such disposition, the number of shares to be disposed of, the amount of proceeds
to be received from such disposition and any other information relating to such
disposition that the Company may reasonably request.  The right of a Participant
to make any such disposition shall be conditioned on the receipt by the Company
of all amounts necessary to satisfy any federal, state or local withholding and
employment-related tax requirements attributable to such disposition.  The
Committee shall have the right, in its sole discretion, to endorse the
certificates representing such shares with a legend restricting transfer and to
cause a stop transfer order to be entered with the Company's transfer agent
until such time as the Company receives the amounts necessary to satisfy such
withholding and employment-related tax requirements or until the later of the
expiration of two years from its date of grant or one year from its date of
exercise and the date on which such shares were transferred to the Participant
pursuant to the exercise of the Option.

6.9    AGGREGATE LIMITATION OF STOCK SUBJECT TO INCENTIVE STOCK OPTIONS.  To
the extent that the aggregate Fair Market Value (determined as of the date an
Incentive Stock Option is granted) of the shares of Common Stock with respect to
which incentive stock options (within the meaning of Section 422 of the Code)
are exercisable for the first time by a Participant during any calendar year
(under the Plan and any other incentive stock option plans of the Company, any
subsidiary or any parent corporation of the Company (within the meaning of
Sections 424(f) and 424(e), respectively, of the Code)) exceeds $100,000 (or
such other amount as may be prescribed by the Code from time to time), such
excess Options shall be treated as Non-Statutory Stock Options.  The
determination shall be made by taking incentive stock options into account in
the order in which they were granted.  If such excess only applies to a portion
of an incentive stock option, the Committee, in its discretion, shall designate
which shares shall be treated as shares to be acquired upon exercise of an
incentive stock option.

7.2    VESTING.  A Restricted Stock Award shall vest at such times and in such
installments, if any, as shall be determined by the Committee in its sole
discretion at the time the Restricted Stock Award is granted.  The Committee may
impose such restrictions or conditions, not inconsistent with the provisions of
the Plan, to the vesting of such Restricted Stock Awards as it deems
appropriate, including, without limitation, that the Participant remain in the
continuous employ or service of the Company or a Subsidiary for a certain
period, or that the Participant or the Company (or any subsidiary or division
thereof) achieve certain performance criteria.  The Committee may, in its sole
discretion, require different restrictions with respect to different
Participants, with respect to different Restricted Stock Awards or with respect
to separate, designated portions of a Restricted Stock Award.  Except as
otherwise provided in Articles 10 and 12 of the Plan, if a Participant's
employment or other service with the Company and all Subsidiaries terminates
prior to the vesting of any Restricted Stock Award, any portion of such
Restricted Stock Award which has not yet vested shall be forfeited, and all
shares of Common Stock (and any dividends and distributions as described in
Section 7.4 of the Plan) related thereto shall be immediately returned to the
Company.

7.3    RIGHTS AS A SHAREHOLDER; TRANSFERABILITY.  A Participant shall have all
voting, dividend, liquidation and other rights with respect to shares of Common
Stock issued to the Participant as a Restricted Stock Award under this Article 7
upon the Participant becoming the holder of record of such Restricted Stock
Award as if such Participant were a holder of record of unrestricted Common
Stock; provided, however, that prior to the vesting of any Restricted Stock
Award, the Participant's right to assign or transfer such shares of Common Stock
issued as a Restricted Stock Award shall be subject to the limitations of
Section 13.2 of the Plan.  As soon as practicable after the vesting of any
Restricted Stock Award, the Company shall cause to be delivered to the
Participant a certificate evidencing such shares of Common Stock together with
any dividends and distributions related thereto.

7.4    DIVIDENDS AND DISTRIBUTIONS.  Unless the Committee determines otherwise
in its sole discretion, any dividends or distributions (including dividends or
distributions paid in cash) paid with respect to shares of Common Stock subject
to a Restricted Stock Award for which the restrictions have not yet ended shall
be subject to the same restrictions as the shares to which such dividends or
distributions relate and shall be promptly deposited with the custodian
designated pursuant to Section 7.5 of the Plan.  The Committee shall determine
in its sole discretion whether any interest shall be paid on such dividends or
distributions.

7.5    ENFORCEMENT OF RESTRICTIONS.  The Committee may, in its sole discretion,
require one or more of the following methods of enforcing the restrictions
referred to in Sections 7.2 and 7.3 of the Plan:  (a) placing a legend on the
stock certificates referring to the restrictions; (b) requiring the Participant
to keep the stock certificates, duly endorsed, in the custody of the Company
while the restrictions remain in effect; or (c) requiring that the stock
certificates, duly endorsed, be held in the custody of a third party while the
restrictions remain in effect.

7.6    LIEN ON SHARES.  The Committee may, in its sole discretion, require that
a Participant, as a condition to the grant of a Restricted Stock Award, grant to
the Company a possessory lien on the shares of Common Stock subject to the
Restricted Stock Award and any dividends or distributions related thereto in
order to (a) secure retransfer of shares of Common Stock subject to a Restricted
Stock Award into the name of the Company, and (b) ensure adequate provision for
any tax withholding obligations arising out of the receipt of, or the lapse or
termination of the restrictions or the payment of any dividends or other
distributions with respect to, a Restricted Stock Award.

       An Eligible Recipient may be granted one or more Stock Bonuses under the
Plan, and such Stock Bonuses shall be subject to such terms and conditions,
consistent with the other provisions of the Plan, as shall be determined by the
Committee in its sole discretion, including, without limitation, that the
Company (or any subsidiary or division thereof) achieve certain performance
criteria.  The Participant shall have all voting, dividend, liquidation and
other rights with respect to the shares of Common Stock issued to the
Participant as a Stock Bonus under this Article 8 upon the Participant becoming
the holder of record of such Stock Bonus; provided, however, that the Committee
may impose such restrictions on the assignment or transfer of a Stock Bonus as
it in its sole discretion deems appropriate.  As soon as practicable after the
grant of a Stock Bonus, the Participant shall be recorded on the stock transfer
books of the Company as the owner of the shares granted, and the Company shall
deliver to the Participant one or more duly issued stock certificates evidencing
such ownership.

       In connection with any grant of Incentive Awards or at any time
thereafter, the Committee may, in its sole discretion, grant a cash bonus to a
Participant in connection with the grant, vesting and/or exercise of an
Incentive Award.  The determination of whether to grant such a cash bonus, the
nature and amount of any such cash bonus and the terms and conditions of such
cash bonus shall be within the sole discretion of the Committee.

     EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER SERVICE ON INCENTIVE AWARDS.

10.1   TERMINATION OF EMPLOYMENT OR OTHER SERVICE DUE TO DEATH, DISABILITY OR
RETIREMENT.  Except as otherwise provided in Article 12 of the Plan, in the
event a Participant's employment or other service with the Company and all
Subsidiaries is terminated by reason of such Participant's death, Disability or
Retirement:  

10.1.1 All outstanding Options then held by the Participant shall, with respect
to termination by reason of death or Disability, become immediately exercisable
in full and remain exercisable for a period of one year after such termination
and shall, with respect to termination by reason of Retirement, remain
exercisable to the extent exercisable as of such termination for a period of
three months after such termination (but in no event shall such Options be
exercisable after the expiration date of any such Option); and

10.1.2 All Restricted Stock Awards then held by the Participant shall become
fully vested and the shares related thereto shall become nonforfeitable.

10.2   TERMINATION OF EMPLOYMENT OR OTHER SERVICE FOR REASONS OTHER THAN DEATH,
DISABILITY OR RETIREMENT.  Except as otherwise provided in Article 12 of the
Plan, in the event a Participant's employment or other service is terminated
with the Company and all Subsidiaries for any reason other 

                                       10
<PAGE>

than death, Disability or Retirement, all rights of the Participant under the 
Plan and any agreement evidencing an Incentive Award shall immediately 
terminate without notice of any kind, no Options then held by the Participant 
shall thereafter be exercisable and any portions of the Restricted Stock 
Awards then held by the Participant that have not vested shall be terminated 
and all shares of Common Stock related thereto shall be forfeited to the 
Company; provided, however, that if such termination is due to any reason 
other than voluntary termination by the Participant or termination by the 
Company or any Subsidiary for "cause," all outstanding Options then held by 
such Participant shall remain exercisable to the extent exercisable as of 
such termination for a period of three months after such termination (but in 
no event after the expiration date of any such Option). For purposes of this 
Section 10.2 "cause" shall be as defined in any employment or other agreement 
or policy applicable to the Participant or, if no such agreement or policy 
exists, shall mean (a) dishonesty, fraud, misrepresentation, embezzlement or 
material or deliberate injury or attempted injury, in each case related to 
the Company or any Subsidiary, (b) any unlawful or criminal activity of a 
serious nature, (c) any willful breach of duty, habitual neglect of duty or 
unreasonable job performance, or (d) any material breach of a confidentiality 
or noncompete agreement entered into with the Company or any Subsidiary.

10.3   MODIFICATION OF EFFECT OF TERMINATION.  Notwithstanding the provisions
of this Article 10, upon a Participant's termination of employment or other
service with the Company and all Subsidiaries, the Committee may, in its sole
discretion (which may be exercised before or following such termination), cause
Incentive Awards, or any portions thereof, then held by such Participant to
become exercisable and remain exercisable following such termination, or to vest
or become free of restrictions following such termination, in each case in the
manner determined by the Committee; provided, however, that no Option shall be
exercisable after the expiration date thereof and any Incentive Stock Option
that remains unexercised more than three months following employment termination
by reason of Retirement or more than one year following employment termination
by reason of Disability shall thereafter be deemed to be a Non-Statutory Stock
Option.

10.4   DATE OF TERMINATION.  Unless the Committee shall otherwise determine in
its sole discretion at the time an Incentive Award is granted, a Participant's
employment or other service shall, for purposes of the Plan, be deemed to have
terminated on the date the Participant ceases to perform services for the
Company, as determined by the Committee in its sole discretion based upon the
Company's personnel records.

                  RIGHT TO WITHHOLD; PAYMENT OF WITHHOLDING TAXES.

11.1   GENERAL RULES.    The Company is entitled to (a) withhold and deduct from
future wages of the Participant (or from other amounts which may be due and
owing to the Participant from the Company or the Parent), or make other
arrangements for the collection of, all legally required amounts necessary to
satisfy any and all federal, state and local withholding and employment-related
tax requirements (i) attributable to the grant, exercise or vesting of, or
payment of dividends with respect to, an Incentive Award or to a disqualifying
disposition of stock received upon exercise of an Incentive Stock Option, or
(ii) otherwise incurred with respect to an Incentive Award, or (b) require the
Participant promptly to remit the amount of such withholding to the Company
before taking any action with respect to an Incentive Award.

11.2   SPECIAL RULES.

11.2.1 Without limiting the generality of Section 11.1 of the Plan, the
Committee may, in its sole discretion and subject to such rules as the Committee
may adopt, permit a Participant to satisfy, in whole or in part, any withholding
or employment-related tax obligation (i) attributable to the grant, exercise or
vesting of, or payment of dividends with respect to, an Incentive Award or to a
disqualifying disposition of stock received upon exercise of an Incentive Stock
Option, or (ii) otherwise incurred with respect to an Incentive Award, by
electing to use Previously Acquired Shares or by electing to have the Company
accept a Broker Exercise Notice with respect to that number of shares, in any
such case, having a Fair Market Value, on the Tax Date, equal to the amount
necessary to satisfy the withholding or employment-related taxes due or by
agreeing to deliver to the Company a promissory note in payment for some or all
of the necessary amounts (containing terms and conditions determined in the
discretion of the Committee).

11.2.2 A Participant's election to use Previously Acquired Shares, a Broker
Exercise Notice or a promissory note must be made on or prior to the Tax Date,
is irrevocable and is subject to the consent or disapproval of the Committee. 
If the Participant is an officer, director or beneficial owner of more than 10%
of the outstanding Common Stock of the Company and the Company has a class of
equity securities registered under Section 12 of the Exchange Act, an election
to use Previously Acquired Shares may not be made within six months of the date
the Incentive Award is granted (unless the death or Disability of the
Participant occurs prior to the expiration of such six-month period), and must
be made either six months prior to the Tax Date or at any time prior to the Tax
Date between the third and twelfth business days following public release of any
of the Company's quarterly or annual summary earnings statements.  When shares
of Common stock are issued prior to the Tax Date to a Participant making an
election to use Previously Acquired Shares, the Participant shall agree in
writing to surrender that number of shares on the Tax Date having an aggregate
Fair Market Value equal to the tax due.

                                 CHANGE OF CONTROL.

12.1   CHANGE IN CONTROL.  For purposes of this Article 12, a "Change in
Control" of the Company shall mean (a) the sale, lease, exchange or other
transfer of all or substantially all of the assets of the Company (in one
transaction or in a series of related transactions) to a corporation that is not
controlled by the Company, (b) the approval by the shareholders of the Company
of any plan or proposal for the liquidation or dissolution of the Company, or
(c) a change in control of the Company of a nature that would be required to be
reported (assuming such event has not been "previously reported") in response to
Item 1(a) of the Current Report on Form 8-K, as in effect on the effective date
of the Plan, pursuant to Section 13 or 15(d) of the Exchange Act, whether or not
the Company is then subject to such reporting requirement; provided, however,
that, without limitation, such a Change in Control shall be deemed to have
occurred at such time as (x) any Person becomes after the effective date of the
Plan the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act),
directly or indirectly, of 50% or more of the combined voting power of the
Company's outstanding securities ordinarily having the right to vote at
elections of directors, or (y) individuals who constitute the board of directors
of the Company on the effective date of the Plan cease for any reason to
constitute at least a majority thereof, provided that any person becoming a
director subsequent to the effective date of the Plan whose election, or
nomination for election by the Company's shareholders, was approved by a vote of
at least a majority of the directors comprising the board of directors of the
Company on the effective date of the Plan (either by a specific vote or by
approval of the proxy statement of the Company in which such person is named as
a nominee 

                                       12
<PAGE>

for director, without objection to such nomination) shall be, for purposes of 
this clause (y), considered as though such person were a member of the board 
of directors of the Company on the effective date of the Plan. 

12.2   ACCELERATION OF VESTING.  If a Change of Control of the Company shall 
occur, then, without any action by the Committee or the Board, (a) all 
outstanding Options shall become immediately exercisable in full and shall 
remain exercisable during the remaining term thereof, regardless of whether 
the Participants to whom such Options have been granted remain in the employ 
or service of the Company or any Subsidiary, and (b) all restrictions with 
respect to outstanding Restricted Stock Awards shall immediately lapse and 
the shares related thereto shall become nonforfeitable.

12.3   CASH PAYMENT FOR OPTIONS.  If a Change in Control of the Company shall
occur, then the Committee, in its sole discretion, and without the consent of
any Participant effected thereby, may determine that some or all Participants
holding outstanding Options shall receive, with respect to some or all of the
shares of Common Stock subject to such Options, as of the effective date of any
such Change in Control of the Company, cash in an amount equal to the excess of
the Fair Market Value of such shares immediately prior to the effective date of
such Change in Control of the Company over the exercise price per share of such
Options.

12.4   LIMITATION ON CHANGE IN CONTROL PAYMENTS.  Notwithstanding anything in
Section 12.2 or 12.3 above to the contrary, if, with respect to a Participant,
the acceleration of the vesting of an Incentive Award as provided in
Section 12.2 or the payment of cash in exchange for all or part of an Option as
provided in Section 12.3 above (which acceleration or payment could be deemed a
"payment" within the meaning of Section 280G(b)(2) of the Code), together with
any other payments which such Participant has the right to receive from the
Company or any corporation which is a member of an "affiliated group" (as
defined in Section 1504(a) of the Code without regard to Section 1504(b) of the
Code) of which the Company is a member, would constitute a "parachute payment"
(as defined in Section 280G(b)(2) of the Code), then the payments to such
Participant pursuant to Section 12.2 or 12.3 above shall be reduced to the
largest amount as will result in no portion of such payments being subject to
the excise tax imposed by Section 4999 of the Code.

          RIGHTS OF ELIGIBLE RECIPIENTS AND PARTICIPANTS; TRANSFERABILITY.

13.1   EMPLOYMENT OR SERVICE.  Nothing in the Plan shall interfere with or
limit in any way the right of the Company or any Subsidiary to terminate the
employment or service of any Eligible Recipient or Participant at any time, nor
confer upon any Eligible Recipient or Participant any right to continue in the
employ or service of the Company or any Subsidiary.

13.2   RESTRICTIONS ON TRANSFER.  Except as expressly permitted by this Plan,
no right or interest of any Participant in an Incentive Award may be
Transferred.  Notwithstanding the foregoing and subject to Articles 10 and 11 of
the Plan, in the event of a Participant's death, such Participant's rights and
interests in any outstanding Options that are exercisable at the time of his
death may be transferred by testamentary will or the laws of descent and
distribution and may be exercised by such Participant's personal representative
or executor for a period of three months following such date of death.  Any
Transfer or attempted Transfer by any Participant in violation of this Section
13.2 shall be null and void and of no effect whatsoever.  By accepting an
Incentive Award, each Participant acknowledges the reasonableness of the
restrictions on Transfer imposed by this Plan in view of the Company's purposes

                                       13

and the purposes of this Plan.  Accordingly, the restrictions on Transfer
contained herein shall be specifically enforceable against any Participant
attempting a Transfer in violation of the provisions contained herein.

13.3   NON-EXCLUSIVITY OF THE PLAN.  Nothing contained in the Plan is intended
to amend, modify or rescind any previously approved compensation plans or
programs entered into by the Company.  The Plan will be construed to be in
addition to any and all such other plans or programs.  Neither the adoption of
the Plan nor the submission of the Plan to the shareholders of the Company for
approval will be construed as creating any limitations on the power or authority
of the Board to adopt such additional or other compensation arrangements as the
Board may deem necessary or desirable.

14.1   SHARE ISSUANCES.  Notwithstanding any other provision of the Plan or any
agreements entered into pursuant hereto, the Company shall not be required to
issue or deliver any certificate for shares of Common Stock under this Plan, and
an Option shall not be considered to be exercised notwithstanding the tender by
the Participant of any consideration therefor, unless and until each of the
following conditions has been fulfilled:

14.1.1 (i) there shall be in effect with respect to such shares a registration
statement under the Securities Act and any applicable state securities laws if
the Committee, in its sole discretion, shall have determined to file, cause to
become effective and maintain the effectiveness of such registration statement;
or (ii) if the Committee has determined not to so register the shares of Common
Stock to be issued under the Plan, (aa) exemptions from registration under the
Securities Act and applicable state securities laws shall be available for such
issuance (as determined by counsel to the Company) and (bb) there shall have
been received from the Participant (or, in the event of death or disability, the
Participant's heir(s) or legal representative(s)) any representations or
agreements requested by the Company in order to permit such issuance to be made
pursuant to such exemptions; and

14.1.2 there shall have been obtained any other consent, approval or permit
from any state or federal governmental agency which the Committee shall, in its
sole discretion upon the advice of counsel, deem necessary or advisable.

14.2   SHARE TRANSFERS.  Shares of Common Stock issued pursuant to Incentive
Awards granted under the Plan may not be Transferred except pursuant to
registration under the Securities Act and applicable state securities laws or
pursuant to exemptions from such registrations.  The Company may condition the
Transfer of such shares not issued pursuant to an effective and current
registration statement under the Securities Act and all applicable state
securities laws on the receipt from the party to whom the shares of Common Stock
are to be so Transferred of any representations or agreements requested by the
Company in order to permit such Transfer to be made pursuant to exemptions from
registration under the Securities Act and applicable state securities laws.

14.3   LEGENDS.  Unless a registration statement under the Securities Act is in
effect with respect to the issuance or Transfer of shares of Common Stock under
the Plan, each certificate representing any such shares shall be endorsed with a
legend in substantially the following form, unless counsel for the Company is of
the opinion as to any such certificate that such legend is unnecessary:

4.   ELIGIBILITY.

     (a)  Any Employee who has been employed by the Company or a Designated
     Subsidiary for at least one year prior to any Offering Date shall be
     eligible to participate in the Plan, beginning with the Offering commencing
     on such Offering Date, subject to the limitations imposed by Section 423(b)
     of the Code.

     (b)  Any provisions of the Plan to the contrary notwithstanding, no
     Employee shall be granted an option under the Plan if:

          (i)  immediately after the grant, such Employee (or any other person
          whose stock ownership would be attributed to such Employee pursuant to
          Section 424(d) of the Code) would own shares of Common Stock and/or
          hold outstanding options to purchase shares of Common Stock possessing
          5% or more of the total combined voting power or value of all classes
          of shares of the Company or of any Subsidiary; or 

          (ii) the amount of payroll deductions that the Employee has elected to
          have withheld under such option (pursuant to paragraph 7 below) would
          permit the Employee to purchase shares of Common Stock under all
          "employee stock purchase plans" (within the meaning of Section 423 of
          the Code) of the Company and its Subsidiaries to accrue (i.e., become
          exercisable) at a rate that exceeds $25,000 of the Fair Market Value
          of such shares of Common Stock (determined at the time such option is
          granted) for each calendar year in which such option is outstanding at
          any time.

5.  OFFERINGS.  Options to purchase shares of Common Stock shall be offered to
Participants under the Plan through a continuous series of Offerings, each
continuing for three months, and each of which shall commence on January 1,
April 1, July 1 and October 1 of each year, as the case may be (the "Offering
Date"), and shall terminate on March 31, June 30, September 30 and December 31
of such year, as the case may be (the "Termination Date").  The first offering
under the Plan shall have an Offering Date of January 1, 1993 and a Termination
Date of March 31, 1993.  Offerings under the Plan shall continue until either
(a) the committee decides, in its sole discretion, that no further Offerings
shall be made because the Common Stock remaining available under the Plan is
insufficient to make an Offering to all eligible Employees, or (b) the Plan is
terminated in accordance with paragraph 17 below.

6.   PARTICIPATION.

     (a)  An eligible Employee may become a Participant in the Plan by
     completing a subscription agreement authorizing payroll deductions on the
     form provided by the Company (the "Participation Form") and filing the
     Participation Form with the Company's Human Resources Department not less
     than 15 days before the Offering Date of the first Offering in which the
     Participant wishes to participate.

     (b)  Except as provided in paragraph 7(a) below, payroll deductions for a
     Participant shall begin with the first payroll following the applicable
     Offering Date, and shall continue until the termination date of the Plan,
     subject to earlier termination by the Participant as provided in paragraph
     11 below or increases or decreases by the Participant in the amount of
     payroll deductions as provided in paragraph 7(c) below.

                                     3
<PAGE>

7.   PAYROLL DEDUCTIONS.

     (a)  By completing and filing a Participation Form, a Participant shall
     elect to have payroll deductions made from his total Compensation (up to a
     maximum of 10% of his total Compensation) on each payday during the time he
     is a Participant in the Plan in such amount as he shall designate on the
     Participation Form; provided, however, that no Participant's payroll
     deductions shall be less than $25.00 per pay period.

     (b)  All payroll deductions authorized by a Participant shall be credited
     to an account established under the Plan for the Participant.  The monies
     represented by such account shall be held as part of the Company's general
     assets, usable for any corporate purpose, and the Company shall not be
     obligated to segregate such monies.  A Participant may not make any
     separate cash payment or contribution to such account.

     (c)  No increases or decreases of the amount of payroll deductions for a
     Participant may be made during an Offering.  A Participant may increase or
     decrease the amount of his payroll deductions under the Plan for subsequent
     Offerings by completing an amended Participation Form and filing it with
     the Company's Human Resources Department not less than 15 days prior to the
     Offering date as of which such increase or decrease is to be effective.

     (d)  A Participant may discontinue his participation in the Plan at any
     time as provided in paragraph 11 below.

8.   GRANT OF OPTION.  On each Offering Date, each eligible Employee who is then
a Participant shall be granted (by operation of the Plan) an option to purchase
(at the Option Price) as many full shares of Common Stock as he will be able to
purchase with (a) the payroll deductions credited to his account during his
participation in the Offering beginning on such Offering Date and (b) the
balance (if any) carried forward from the Employee's payroll deduction account
from the preceding Offering.  The option price per share of such shares (the
"Option Price") shall be the lower of (a) 85% of the Fair Market Value of one
share of Common Stock on the Offering Date, or (b) 85% of the Fair Market Value
of one share of Common Stock on the Termination Date.

9.   EXERCISE OF OPTION.

     (a)  Unless a Participant gives written notice to the Company as provided
     in subparagraph 9(d) below or withdraws from the Plan pursuant to paragraph
     11 below, his option for the purchase of shares of Common Stock granted for
     an Offering will be exercised automatically at the Termination Date of such
     Offering for the purchase of the number of full shares of Common Stock that
     the accumulated payroll deductions in his account on such Termination Date
     will purchase at the applicable Option Price.

     (b)  A Participant may only purchase one or more full shares in connection
     with the automatic exercise of an option granted for any Offering.  That
     portion of any balance remaining in a Participant's payroll deduction
     account at the close of business on the Termination Date of any Offering
     that is less than the purchase price of one full share will be carried
     forward into the Participant's payroll deduction account for the following
     Offering.  In no event will the balance carried forward be equal to or
     greater than the purchase price of one share on the Termination Date of an
     Offering.

                                     4
<PAGE>

     (c)  No Participant (or any person claiming through such Participant) shall
     have any interest in any Common Stock subject to an option under the Plan
     until such option has been exercised, at which point such interest shall be
     limited to the interest of a purchaser of the Common Stock purchased upon
     such exercise pending the delivery of such Common Stock in accordance with
     paragraph 10 below.  During his lifetime, a Participant's option to
     purchase shares of Common Stock under the Plan is exercisable only by him.

     (d)  By written notice to the Company prior to the Termination Date of any
     Offering, a Participant may elect, effective on such Termination Date, to:

          (i)  withdraw all of the accumulated payroll deductions in his account
          as of the Termination Date (which withdrawal may, but need not, also
          constitute a notice of termination and withdrawal pursuant to
          paragraph 11(a)); or 

          (ii) exercise his option for a specified number of full shares, not
          less than five, that is less than the number of full shares of Common
          Stock that the accumulated payroll deductions in his account will
          purchase on the Termination Date of the Offering at the applicable
          Option Price, and withdraw the balance in his payroll deduction
          account.

10.  DELIVERY.  As promptly as practicable after the Termination Date of each
Offering, the Company will deliver to each Participant, as appropriate, either:

     (a)  (i) a certificate representing the shares of Common Stock purchased
     upon exercise of his option granted for such offering, registered in the
     name of the Participant or, if the Participant so directs on his
     Participation Form, in the names of the Participant and his spouse, and
     (ii) in the event the Participant makes an election pursuant to paragraph
     9(d)(ii), a check in the amount of the balance of any payroll deductions
     credited to his account that were not used for the purchase of Common
     Stock; or 

     (b)  if the Participant makes an election pursuant to paragraph 9(d)(i) for
     the Offering, a cash payment equal to the total of the payroll deductions
     credited to his account.

11.  WITHDRAWAL; TERMINATION OF EMPLOYMENT.

     (a)  A Participant may terminate his participation in the Plan and withdraw
     all, but not less than all, the payroll deductions credited to his account
     under the Plan at any time prior to the Termination Date of an Offering,
     for such Offering, by giving written notice to the Company.  Such notice
     shall state that the Participant wishes to terminate his involvement in the
     Plan, specify a termination date and request the withdrawal of all of the
     Participant's payroll deductions held under the Plan.  All of the
     Participant's payroll deductions credited to his account will be paid to
     him as soon as practicable after the termination date specified in the
     notice of termination and withdrawal (or, if no such date is specified, as
     soon as practical after receipt of his notice of termination and
     withdrawal), and his option for such Offering will be automatically
     canceled, and no further payroll deductions for the purchase of shares of
     Common Stock will be made for such Offering or for any subsequent Offering,
     except in accordance with a new Participation Form filed pursuant to
     paragraph 6 above. 

     (b)  Upon termination of a Participant's employment for any reason,
     including retirement or death, the payroll deductions accumulated in his
     account will be returned to him as soon as 

                                     5
<PAGE>

     practicable after such termination or, in the case of his death, to 
     the person or persons entitled thereto under paragraph 14 below, 
     and his option will be automatically canceled.  For purposes of the 
     Plan, the termination date of employment shall be the Participant's 
     last date of actual employment and shall not include any period 
     during which such Participant receives any severance payments.  A 
     transfer of employment between the Company and a Designated 
     Subsidiary or between one Designated Subsidiary and another 
     Designated Subsidiary, or absence or leave approved by the Company, 
     shall not be deemed a termination of employment under this 
     subparagraph 11(b).

     (c)  A Participant's termination and withdrawal pursuant to subparagraph
     11(a) above will not have any effect upon his eligibility to participate in
     a subsequent Offering by completing and filing a new Participation Form
     pursuant to paragraph 6 above or in any similar plan that may hereafter be
     adopted by the Company; provided, however, that, unless otherwise permitted
     by the Committee in its sole discretion, a Participant who is an Insider
     may not participate in the Plan for at least six months after the effective
     date of his termination and withdrawal.

12.  INTEREST.  No interest shall accrue on a Participant's payroll deductions
under the Plan.

13.  STOCK SUBJECT TO THE PLAN.

     (a)  The maximum number of shares of Common Stock that shall be reserved
     for sale under the Plan shall be 225,000 shares, subject to adjustment upon
     changes in capitalization of the Company as provided in subparagraph (b)
     below.  The shares to be sold to Participants under the Plan may be, at the
     election of the Company, either treasury shares or shares authorized but
     unissued.  If the total number of shares of Common Stock that would
     otherwise be subject to options granted pursuant to paragraph 8 above on
     any Termination Date exceeds the number of shares then available under the
     Plan (after deduction of all shares for which options have been exercised
     or are then outstanding), the Company shall make a pro rata allocation of
     the shares of Common Stock remaining available for issuance in as uniform
     and equitable a manner as is practicable.  In such event, the Company shall
     give written notice of such reduction of the number of shares subject to
     the option to each Participant affected thereby and shall return any excess
     funds accumulated in each Participant's account as soon as practicable
     after the Termination Date of such Offering.

     (b)  If any option under the Plan is exercised after any Common Stock
     dividend, split-up, recapitalization, merger, consolidation, combination or
     exchange of Common Stock or the like, occurring after the shareholders of
     the Company approve the Plan, the number of shares of Common Stock to which
     such option shall be applicable and the Option Price for such Common Stock
     shall be appropriately adjusted by the Company.

14.  DESIGNATION OF BENEFICIARY.

     (a)  A Participant may file a written designation of a beneficiary who is
     to receive shares of Common Stock and/or cash, if any, from the
     Participant's account under the Plan in the event of such Participant's
     death at a time when cash or shares of Common Stock are held for his
     account.

     (b)  Such designation of beneficiary may be changed by the Participant at
     any time by written notice.  In the event of the death of a Participant in
     the absence of a valid designation of a beneficiary who is living at the
     time of such Participant's death, the Company shall deliver such 

                                     6
<PAGE>

     shares of Common Stock and/or cash to the executor or administrator of the 
     estate of the Participant; or, if no such executor or administrator has 
     been appointed (to the knowledge of the Company), the Company, in its
     discretion, may deliver such shares of Common Stock and/or cash to the
     spouse or to any one or, more dependents or relatives of the Participant;
     or, if no spouse, dependent or relative is known to the Company, then to
     such other person as the Company may designate.

15.  TRANSFERABILITY.  Neither payroll deductions credited to a Participant's
account nor any rights with regard to the exercise of an option or to receive
shares of Common Stock under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in paragraph 14 above) by the Participant.  Any
such attempt at assignment, transfer, pledge or other disposition shall be
without effect, except that the Company may treat such act as an election to
withdraw funds in accordance with paragraph 11(a) above.

16.  SHARE TRANSFER RESTRICTIONS.

     (a)  Shares of Common Stock shall not be issued under the Plan unless such
     issuance is either registered under the Securities Act and applicable state
     securities laws or is exempt from such registrations.

     (b)  Shares of Common Stock issued under the Plan may not be sold,
     assigned, transferred, pledged, encumbered, or otherwise disposed of
     (whether voluntarily or involuntarily) except pursuant to registration
     under the Securities Act and applicable state securities laws, or pursuant
     to exemptions from such registrations.

     (c)  Notwithstanding any other provision of the Plan or any documents
     entered into pursuant to the Plan and except as permitted by the Committee
     in its sole discretion, any shares of Common Stock issued to a Participant
     who is an Insider may not be sold, assigned, transferred, pledged,
     encumbered or otherwise disposed of for a six-month period after the
     Termination Date of the Offering with respect to which they were issued.

     (d)  LEGENDS.  Each certificate representing shares of Common Stock issued
     under the Plan to an Insider shall be stamped with a legend in
     substantially the following form, unless the Committee, in its sole
     discretion, determines not to require such a legend:

     THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD,
     TRANSFERRED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF ON OR
     BEFORE [INSERT APPROPRIATE DATE] WITHOUT THE PRIOR WRITTEN CONSENT OF
     THE COMPANY.


17.  AMENDMENT OR TERMINATION.  The Plan may be amended by the Board from time
to time to the extent that the Board deems necessary or appropriate in light of,
and consistent with, Section 423 of the Code; provided, however, that no such
amendment shall be effective, without approval of the shareholders of the
Company, if shareholder approval of the amendment is then required pursuant to
Rule 16b-3 under the Exchange Act or any successor rule or Section 423 of the
Code.  The Board also may terminate the Plan or the granting of options pursuant
to the Plan at any time; provided, however, that the Board shall not have the
right to modify, cancel, or amend any outstanding option granted pursuant to the
Plan before such termination unless each Participant consents in writing to such
modification, amendment or cancellation.

                                     7
<PAGE>

18.  NOTICES.  All notices or other communications by a Participant to the
Company in connection with the Plan shall be deemed to have been duly given when
received by the Treasurer of the Company or by any other person designated by
the Company for the receipt of such notices or other communications, in the form
and at the location specified by the Company.

19.  EFFECTIVE DATE OF PLAN.  The Plan shall be effective as of June 24, 1992,
the date it was adopted by the Board.  The Plan has been adopted by the Board
subject to shareholder approval, and prior to shareholder approval shares of
Common Stock may be issued under the Plan subject to such approval.

20.  MISCELLANEOUS.  The headings to paragraphs in the Plan have been included
for convenience of reference only.  The masculine pronoun shall include the
feminine and the singular the plural, whenever appropriate.  Except as otherwise
expressly indicated, all references to paragraphs in the Plan shall be to
paragraphs of the Plan.  The Plan shall be interpreted and construed in
accordance with the laws of the State of Minnesota.
