                                ATS MEDICAL, INC.
                                 PROXY STATEMENT


         This proxy statement is furnished in connection with the solicitation
of the enclosed proxy by the Board of Directors of ATS Medical, Inc. (the
"Company") for use at the 2003 Annual Meeting of Shareholders to be held on
Wednesday, April 30, 2003 at 3:30 p.m. at the Minneapolis Club, 729 Second
Avenue South, Minneapolis, Minnesota 55402, and at any adjournments thereof. On
March 7, 2003, the Company had outstanding 22,324,990 shares of common stock
(the "Common Stock"). Each holder of record of Common Stock as of the close of
business on March 7, 2003 will be entitled to one vote on all matters being
presented at the meeting for each share of Common Stock held on such date.
Shareholders who sign and return a proxy may revoke it at any time before it is
voted by giving written notice to the Secretary of the Company. This proxy
statement and the enclosed proxy card are being mailed to shareholders
commencing on or about March 28, 2003.

         Proxies that are completed, signed and returned to the Company prior to
the Annual Meeting will be voted as specified. If no direction is given, the
proxy will be voted for the election of the nominees for director named in this
proxy statement and for the management proposals discussed herein and in
accordance with the judgment of the persons named in the proxy as to any other
matters that properly come before the meeting. If a shareholder abstains from
voting as to any matter (or indicates a "withhold vote for" as to directors),
then the shares held by such shareholder shall be deemed present at the Annual
Meeting for purposes of determining a quorum and for purposes of calculating the
vote with respect to such matter, but shall not be deemed to have been voted in
favor of such matter. If a broker returns a "non-vote" proxy, indicating a lack
of authority to vote on such matter, then the shares covered by such non-vote
shall be deemed present at the Annual Meeting for purposes of determining a
quorum but shall not be deemed to be represented at the Annual Meeting for
purposes of calculating the vote with respect to such matters.

PROPOSAL 1 - ELECTION OF DIRECTORS

         Five directors have been nominated for election to the Company's Board
of Directors at the 2003 Annual Meeting of Shareholders to hold office for a
term of one year and until their successors are duly elected and qualified
(except in the case of earlier death, resignation or removal). The accompanying
proxy is intended to be voted for the election of nominees for director named
below, unless authority to vote for one or more nominees is withheld as
specified on the proxy card. The affirmative vote of a majority of the shares of
Common Stock represented at the Annual Meeting is required for the election of
each director, and cumulative voting is not permitted. In the event that any
nominee becomes unable or unwilling to serve as a director for any reason, the
persons named in the enclosed proxy will vote for a substitute nominee in
accordance with their best judgment. The





Board of Directors has no reason to believe that any nominee will be unable or
unwilling to serve as a director if elected.

         Each nominee has furnished to the Company the following information
with respect to his principal occupations or employment during the last five
years, his directorships of other companies subject to the reporting

COMMITTEES OF THE BOARD OF DIRECTORS AND ATTENDANCE

         The Company has an Audit Committee whose functions are to review and
monitor accounting policies and control procedures of the Company, including
recommending the engagement of independent auditors and reviewing the scope of
the audit. The Audit Committee, on which Messrs. Boehnen and Graf, as well as
Mr. Villafana, served in 2002, held four meetings during 2002. Under Nasdaq
rules applicable to companies quoted on the Nasdaq National and SmallCap
Markets, the Company's Audit Committee must be comprised of three or more
non-employee directors, one of whom can be, under exceptional and limited
circumstances, non-independent as defined in the Nasdaq rules. Other than
Messrs. Boehnen and Graf, Mr. Villafana was the only director eligible to be a
member of the Audit Committee in 2002. Although Mr. Villafana was not an
independent director during 2002 under applicable Nasdaq rules, the Board
determined that it was in the best interest of the Company and its shareholders
to appoint Mr. Villafana to the Audit Committee during 2002 in order to satisfy
the Nasdaq rules. A new non-employee independent director, Mr. Eric W. Sivertson
joined the Board in 2003 and the Board appointed Mr. Sivertson in February 2003
to the Audit Committee to replace Mr. Villafana.




                                       3


         The Company also has a Compensation Committee which reviews and
establishes compensation levels for each of the Company's officers, as well as
jointly administers the Company's stock plans with the Board of Directors. The
Compensation Committee, on which Mr. Graf and Mr. Boehnen serve, held one formal
meeting during 2002. On February 27, 2003, Mr. Sivertson was appointed to be a
third member of the Compensation Committee of the Company. The Company does not
have a standing nominating committee. The Board of Directors held eight meetings
during 2002. Each Director attended 100% of the meetings of the Board and all
meetings of each committee of which he was a member.

REPORT OF THE AUDIT COMMITTEE
OF THE BOARD OF DIRECTORS

         The Audit Committee of our Board of Directors is composed of the
following non-employee directors: Messrs. Boehnen, Sivertson and Graf. Mr.
Boehnen currently serves as the Chairman of the Audit Committee. All of the
members of the Audit Committee are independent for purposes of the Nasdaq
listing requirements. On February 27, 2002, Mr. Sivertson was appointed to
replace Mr. Villafana on the Audit Committee. The Audit Committee operates under
a written charter adopted by the Board of Directors. The Audit Committee
recommends to the Board of Directors, and submits for shareholder ratification,
the appointment of the Company's independent auditors.

         Management is responsible for the Company's internal controls and the
financial reporting process. Our independent auditors are responsible for
performing an independent audit of our consolidated financial statements in
accordance with generally accepted auditing standards and to issue a report on
our financial statements. The Audit Committee's responsibility is to monitor and
oversee these processes.

         In this context, the Audit Committee has met and held discussions with
management and the independent auditors. Management represented to the Audit
Committee that the Company's consolidated financial statements were prepared in
accordance with generally accepted accounting principles, and the Audit
Committee has reviewed and discussed the consolidated financial statements with
management and the independent auditors. The Audit Committee discussed with the
independent auditors matters required to be discussed by Statement on Auditing
Standards No. 61 (Communications with Audit Committees).

         The Company's independent auditors also provided to the Audit Committee
the written disclosure required by Independence Standards Board Standard No. 1
(Independence Discussions with Audit Committees), and the Audit Committee
discussed with the independent auditors the auditing firm's independence. The
Committee also considered whether non-audit services provided by the independent
auditors during the last fiscal year were compatible with maintaining the
independent auditors' independence.




                                       4


         Based upon the Audit Committee's discussion with management and the
independent auditors and the Audit Committee's review of the representation of
management and the report of the independent auditors to the Audit Committee,
the Audit Committee recommended to the Board of Directors that the audited
consolidated financial statements be included in Company's Annual report on Form
10-K for the fiscal year ended December 31, 2002 filed with the Securities and
Exchange Commission.

                                             Members of the Audit Committee
                                             David L. Boehnen, Chairman
                                             Eric W. Sivertson
                                             A. Jay Graf


COMPENSATION OF DIRECTORS

         The directors of the Company do not receive any cash compensation for
their services on the Board of Directors, except for Mr. Villafana under a
consulting agreement with the Company described below. Upon their initial
election to the Board of Directors, each outside director receives an option to
purchase 5,000 shares of Common Stock at the fair market value on the date of
election under the 2000 Stock Incentive Plan. Upon each reelection, each outside
director receives an option to purchase 2,500 shares of Common Stock at the fair
market value on the date of reelection under the Plan. However, the Board of
Directors decided to suspend the option grant to non-employee directors related
to their 2002 reelection to the Board for 2002. As a result, the outside
directors did not receive any stock options in 2002, except for Mr. Sivertson,
who received an option to purchase 5,000 shares of Common Stock upon his
appointment to the Board of Directors.

         Mr. Villafana serves as Chairman of the Board of Directors and provides
consulting services to the Company under a consulting agreement dated January
26, 1995, which was amended in April 1998, September 2001, and most recently in
October 2002. Prior to January 1, 2002, Mr. Villafana was the Chief Executive
Officer of the Company. Mr. Villafana's fees under his consulting agreement for
2002 were $241,130. Mr. Villafana did not receive any stock options during 2002.
Mr. Villafana's consulting fees for each year are determined by the Compensation
Committee on a yearly basis. The consulting agreement, as amended, will
terminate on December 31, 2003 if the Company delivers to Mr. Villafana a notice
of non-renewal of the consulting agreement by November 1, 2003. The consulting
agreement also contains a non-competition agreement pursuant to which Mr.
Villafana agreed not to compete with the Company during the term of the
agreement and for a period of two years following his termination of consulting
services to the Company. In exchange, the Company has agreed to continue Mr.
Villafana's monthly consulting fees during the period of non-competition
restriction, adjusted annually to take into account increases in the consumer
price index.

                          CHANGE IN CONTROL AGREEMENTS

         The Company has entered into agreements with its officers providing for
the payment of certain benefits to the officers if their employment terminates
following a "change in control" of the Company. The Agreements provide for
benefits if an officer's employment is terminated within 24 months following a
change in control unless such termination was by the Company for cause, by the
officer other than for "good reason," or because of the officer's death. "Good
reason" is defined as the termination of employment as a result of either a
diminution in the officer's responsibilities, a reduction in salary or benefits,
a relocation of the Company's office of more than 35 miles or for any reason
during the sixth month following a change in control. A "change in control" is
generally defined as an acquisition of more than 20% of the outstanding Common
Stock by any person or group, the merger or sale of the Company or the
replacement of a majority of the Company's Board of Directors with directors not
recommended by the existing Board of Directors. The Agreements provide for lump
sum payments following termination in amounts equal to three times the sum of
the officer's base salary and any annual target bonus potential, as limited by
Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"). If
there had been a change in control of the Company as of the end of 2002 and the
employment of the two executive officers named in the Summary Compensation Table
had been immediately terminated, Mr. Dale would have been entitled to receive,
pursuant to the terms of the Agreement, a lump sum payment upon termination of
$900,000. Mr. Kramp is no longer employed by the Company, so he is not eligible
to receive change in control payments.

                      REPORT OF THE COMPENSATION COMMITTEE
                        CONCERNING EXECUTIVE COMPENSATION

OVERVIEW

         The Compensation Committee is responsible for setting the compensation
and benefits of the Company's executive officers, including the Chief Executive
Officer, on behalf of the Board of Directors and the shareholders. The
Compensation Committee also oversees the operation of the 1998 Employee Stock
Purchase Plan (the "Stock Purchase Plan") and the ATS Medical, Inc. 2000 Stock
Incentive Plan (the "Plan").

         The Compensation Committee was composed entirely of non-employee
directors of the Company in 2002. Messrs. Boehnen, Graf and Sivertson are each
non-employee directors of the Company and currently comprise the Compensation
Committee.

         The basic objective of the Compensation Committee is to establish a
compensation package which is appropriate for each officer's scale of
responsibility and performance, commensurate with


                                       9


the marketplace compensation for executives of companies of similar size as the
Company, and to attract, motivate and retain executives of the necessary
caliber. The Committee intends to achieve these objectives by giving executives
the opportunity for equity ownership in the Company through stock options and by
awarding bonuses tied to individual and Company performance as significant
elements of the executive compensation package.

COMPENSATION CRITERIA

         In determining each executive compensation package, the Compensation
Committee reviews the compensation of each executive and the individual
achievements and performance of each such executive during the year. The
Committee considers objective criteria, such as salary survey data of companies
of similar size and technology as the Company, in determining executive
salaries. The financial performance and accomplishments of the Company during
the year are also factors in the Committee's determination of executive
compensation. In line with the Compensation Committee's goal of tying
compensation with performance, executives' salaries are generally increased only
to keep up with estimated cost-of-living expenses, while bonuses vary
substantially from year to year and have generally depended upon the performance
of the Company and the individual executive. The Committee generally makes a
determination as to salaries for the current calendar year and reviews bonuses
to be awarded for the prior year at the end of the prior year or at the
beginning of the current year.

         In 2002, the Compensation Committee continued to place emphasis on
performance-based criteria to determine bonuses to employees for 2002. In
particular, the Committee evaluated whether to grant any bonuses during 2002 to
its executive officers under the Management Incentive Compensation Plan (the
"MICP"), which is the Company's bonus program for its executive employees. Under
the MICP, bonuses to be granted to executive employees were tied to a grid
representing year-over-year increases in sales and operating income.

         In addition, the Compensation Committee, in consultation with the Chief
Executive Officer, generally grants stock options to its executive officers on
an annual basis to maintain and increase the executives' incentive to continue
their long-term employment with the Company. The Compensation Committee may also
approve special grants to certain executives to reward their individual
performance. The overall compensation package may also be varied if the
Committee feels that it is necessary to maintain the Company's executive
compensation in line with companies similar in size and technology to the
Company.

EXECUTIVE COMPENSATION PACKAGE

         The primary components of the executive compensation package are
salary, bonuses and stock option grants. The Company also currently maintains a
variety of employee benefits in which its executive officers may participate,
including health benefits, automobile allowances, disability


                                       10


insurance, matching contributions to the Company's 401(k) program and
discounting the purchase of a certain number of shares of the Company's Common
Stock pursuant to the Stock Purchase Plan.

         The Compensation Committee took the following actions with respect to
executive compensation for 2002:

         -    Continued suspension of the MICP due to projected losses from
              operations;

         -    Refrained from granting any new stock option grants to the former
              executive officers of the Company; and

         -    Retained a 10% salary reduction for each of the executive officers
              that was implemented in September 2001 through the date of
              termination of the former executive officers of the Company.

         In December 2002, the Company hired Mr. Richard Curtis as Vice
President of Marketing and Business Development. Mr. Curtis' initial
compensation package, consisting or annual salary, potential for bonus and grant
of stock options, was based on subjective criteria. When negotiating with Mr.
Curtis prior to his hiring, the Committee concluded that the salary, bonus and
grant of stock options offered to Mr. Curtis were necessary and appropriate to
attract him to the Company.

         In 2003, the Committee intends to continue to emphasize objective
factors and performance in determining executive compensation. The Committee
expects to consider as well whether to replace the MICP with a new plan that
will tie bonuses to more individual goals and achievements. The Committee will
continue to use stock options as part of executive compensation in 2003 to
provide additional performance incentives.

COMPENSATION OF THE CHIEF EXECUTIVE OFFICER

         In September 2002, the Company hired Mr. Dale as its President and
Chief Executive Officer. In connection with his hiring, Mr. Dale received a
$100,000 signing bonus and also entered into an at will employment agreement
which entitles him to a base salary of $250,000 and a potential bonus of $50,000
based on sales and earnings criteria to be determined by the Board. In addition,
Mr. Dale received options for the purchase of 400,000 shares of Common Stock.
The Board felt that Mr. Dale's signing bonus and salary compensation were
appropriate in light of the challenges and difficult competitive environment
facing the Company. The potential to earn an additional $50,000 bonus based on
sales and earnings criteria to be determined by the Board was deemed by the
Board to be an incentive for Mr. Dale to improve these key components of the
Company's financial performance in the short term. The primary basis for the
Board's decision to grant to Mr. Dale stock options was to provide a significant
incentive for him to enhance shareholder value over the long term. The number


                                       11


of options granted to Mr. Dale was based on negotiations with him prior to his
hiring, and the Committee's conclusion that the number of options was necessary
and appropriate to attract Mr. Dale to this position.

SECTION 162(m) OF THE INTERNAL REVENUE CODE

         Section 162(m) of the Code generally limits the corporate deduction for
compensation paid to executive officers to $1.0 million, unless the compensation
qualifies as a "performance-based compensation" under the Code. Compensation
resulting from stock options granted under the Plan or the Stock Purchase Plan
will not be counted toward the $1.0 million of deductible compensation under
Section 162(m). The Committee does not believe that the annual compensation for
Section 162(m) purposes of any of the Company's executive officers will exceed
$1.0 million in fiscal 2003.

SECTION 16(a) BENEFICIAL OWNERSHIP
REPORTING COMPLIANCE

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Company's directors and executive officers and all persons who beneficially own
more than 10% of the outstanding shares of the Company's Common Stock to file
with the Securities and Exchange Commission initial reports of ownership and
reports of changes in ownership of such Common Stock. Directors, executive
officers and 10% or more beneficial owners are also required to furnish the
Company with copies of all Section 16(a) reports they file. Based solely on a
review of the copies of such forms furnished to the Company, the Company
believes that all Section 16(a) filing requirements applicable to its executive
officers, directors and 10% shareholders were complied with, except that: (a)
Mr. Curtis did not timely file a Form 3 to report his initial appointment as an
executive officer of the Company and a Form 4 to report an initial grant of
stock options to him, (b) Mr. Dale did not timely report a stock option grant on
Form 4, (c) due to a software error, a purchase of shares by Mr. Villafana was
reported incorrectly on a Form 4 that was timely filed but that was subsequently
amended to correct the error and (d) Ms. Deborah K. Chapman, Controller, did not
timely file a Form 3 when she became an officer of the Company in June 2002.

PROPOSAL 2 - PROPOSAL TO AMEND THE
ATS MEDICAL, INC. 2000 STOCK INCENTIVE PLAN

         The Board of Directors has adopted, subject to shareholder approval,
amendments to the Company's 2000 Stock Incentive Plan (the "Plan") to:

         -    increase the number of shares of Common Stock authorized for
              issuance under the Plan from 1,000,000 to 2,000,000, an increase
              of 1,000,000 shares, all of which may be granted as stock options
              that qualify as incentive stock options ("Incentive Stock
              Options") meeting the requirements of Section 422 of the Code;

         -    fix the maximum term of any option granted under the Plan at no
              more than 10 years;

         -    prohibit stock option repricing; and

         -    remove the availability under the Plan of discounted options,
              reload options and restricted stock.

         The Board of Directors recommends that you vote in favor of the
amendments to the Plan. If the amendments to the Plan are approved by the
required number of shareholders, as described below, the amendments will be
effective on April 30, 2003. If the amendments are not approved by our
shareholders, they will not take effect. The proposed amendments are discussed
in greater detail below.

INCREASE IN AUTHORIZED SHARES

         We propose to amend the Plan to increase the number of shares of our
Common Stock available for issuance pursuant to the Plan from 1,000,000 to
2,000,0000, an increase of 1,000,000 shares. We further propose to amend the
Plan by allowing up to all of the additional 1,000,000 shares available under
the Plan to be issued as stock options that qualify as Incentive Stock Options,
if these amendments are approved by the shareholders. As of December 31, 2002,
19,263 shares of our Common Stock remained available for future grants of stock
options and other awards available under the Plan. The Board of Directors
believes that stock options have been, and will continue to be an important
compensation element in attracting, motivating and retaining key employees. The
granting of Incentive Stock Options to employees is consistent with the
Company's past practices, with practices in the industry, and is a factor in
promoting the long-term development of the Company. The Board of Directors
believes that the increase in authorized shares is necessary because of the need
to continue to make awards under the Plan to attract, motivate and retain key
employees.




                                       16


MAXIMUM OPTION TERM

         We propose to amend the Plan to limit the maximum term of any stock
option granted under the Plan to 10 years. We have not granted and do not intend
to grant stock options with terms longer than 10 years, and we believe that the
Plan should be amended to reflect past practice and our future intentions.

PROHIBITION ON OPTION REPRICING

         We propose to amend the Plan to prohibit the "repricing" of stock
options. This amendment would prohibit the Company from lowering the exercise
price of outstanding stock options granted under the Plan whether through
amendment or through cancellation and replacement grants of options. The Board
of Directors believes that prohibiting the repricing of outstanding options will
further align the Plan with the interests of the shareholders. Although this
proposed amendment is consistent with the Company's past practice of not
repricing options, we want to assure shareholders that we will not engage in
this practice in the future without shareholder approval.

ELIMINATION OF DISCOUNTED OPTIONS, RELOAD OPTIONS AND RESTRICTED STOCK

         We propose to amend the Plan by eliminating the Company's ability to
issue stock options under the Plan with a purchase price below the fair market
value of the Common Stock at the time of grant. Under the requirements of
Section 422 of the Code, Incentive Stock Options must have a purchase price
equal to or greater than fair market value at the time of grant. Thus, the
effect of this amendment would be to prohibit the Company from granting stock
options that do not meet the requirements of Section 422 of the Code
("Non-Qualified Stock Options") with a purchase price below the fair market
value of the Common Stock at the time of grant. The Company has never issued
below-fair market value purchase price Non-Qualified Stock Options, and we do
not expect to make this type of award in the future. We want to assure
shareholders that we will not issue below fair market value purchase price
Non-Qualified Stock Options pursuant to the Plan without shareholder approval.

         We further propose to amend the Plan by eliminating the availability of
"reload options." A reload option allows the optionee to purchase the number of
shares which the optionee has delivered as payment for exercise of an option
and/or delivered or withheld as payment for taxes in connection with the
exercise of an option. The Company has never issued reload options pursuant to
the Plan, and we do not expect to make this type of award in the future. We
again want to assure shareholders that we will not issue reload options pursuant
to the Plan without shareholder approval.

         Our final proposal to amend the Plan is to eliminate our ability to
issue restricted stock under the Plan. Unlike stock options, restricted stock
awards are generally granted to employees


                                       17


without payment of any cash consideration by the employee receiving the award.
We have not granted this type of award in the past, and we do not expect to make
this type of award in the future. This change is being proposed to assure
shareowners that this alternative form for stock-based compensation not be
granted under the Plan without their prior approval.

                               SUMMARY OF THE PLAN

         The Plan currently permits the granting of (a) stock options, including
Incentive Stock Options and Non-Qualified Stock Options, (b) stock appreciation
rights ("SARs"), (c) restricted stock and restricted stock units, (d)
performance awards, and (e) other awards valued in whole or in part by reference
to or otherwise based upon the Common Stock ("Other Stock Grants") (all of these
grants are referred to collectively as "Awards"). The Plan provides for the
grant of Awards to any full or part-time employee, officer, consultant,
independent contractor, or director providing services to the Company. Stock
options granted to full or part-time employees may qualify as Incentive Stock
Options under the Code or may be Non-Qualified Stock Options. Options granted to
persons who are not full or part-time employees of the Company may not qualify
as Incentive Stock Options under the Code. The Plan is administered by the
Committee, which is comprised of non-employee directors selected by the Board.
The Compensation Committee (the "Committee") has the authority to: (i) designate
participants; (ii) determine the type or types of Awards to be granted to each
participant under the Plan; (iii) determine the number of shares of Common Stock
("Shares") to be covered by (or with respect to which payments, rights or other
matters are to be calculated in connection with) each Award; (iv) determine the
terms and conditions of any Award or Award agreement; (v) amend the terms and
conditions of any Award or Award agreement and accelerate the exercisability of
stock options or the lapse of restrictions relating to restricted stock,
restricted stock units or other Awards; (vi) determine whether, to what extent
and under what circumstances Awards may be exercised in cash, Shares, other
securities, other Awards or other property, or canceled, forfeited or suspended;
(vii) determine whether, to what extent and under what circumstances cash,
Shares, promissory notes, other securities, other Awards, other property and
other amounts payable with respect to an Award under the Plan may be deferred
either automatically or at the election of the holder thereof or the Committee;
(viii) interpret and administer the Plan and any instrument or agreement,
including an Award agreement, relating to the Plan; (ix) establish, amend,
suspend or waive such rules and regulations and appoint such agents as it shall
deem appropriate for the proper administration of the Plan; and (x) make any
other determination and take any other action that the Committee deems necessary
or desirable for the administration of the Plan. If the shareholders approve the
amendment to the Plan, the Company would not be allowed to reprice stock options
granted under the Plan.

         Under the Plan, the aggregate number of Shares that may be issued under
all Awards currently is 1,000,000. In addition, the number of shares available
for granting Incentive Stock Options under the Plan is also 1,000,000. If the
amendment to increase the number of shares under the Plan is accepted, the total
number of shares that may be issued under all Awards will be 2,000,000, and the
number of shares available for granting Incentive Stock Options will be
increased to the same


                                       18


number. The Plan provides that no employee may be granted Awards under the Plan,
the value of which Awards is based solely on an increase in the value of the
Shares after the date of grant of such Award, for more than 300,000 Shares in
the aggregate in any calendar year. Determinations and interpretations with
respect to the Plan are in the sole discretion of the Committee, whose
determinations and interpretations are final and conclusive. The Plan terminates
on December 31, 2010, and no Awards may be granted after such date.

         Awards may be granted for no cash consideration or for such minimal
cash consideration as may be required by applicable law. Awards may provide that
upon grant or exercise thereof the holder will receive Shares, cash or any
combination thereof, as the Committee shall determine. The exercise price of an
Incentive Stock Option granted under the Plan is determined by the Committee,
but may not be less than 100% of the fair market value of the underlying Common
Stock on the date of the grant. The exercise price of any Non-Qualified Stock
Option granted under the Plan is determined by the Committee, but may not be
less than 50% of the fair market value of the underlying Common Stock on the
date of grant. Determinations of fair market value under the Plan must be made
in accordance with the methods and procedures established by the Committee.
Notwithstanding the foregoing, unless otherwise determined by the Committee, the
fair market value of Shares on a given date is the closing price of the Shares
as reported on the Nasdaq SmallCap Market System on the date of grant of the
Award ("Fair Market Value"). If the shareholders approve the amendments to the
Plan, Non-Qualified Stock Options will only be able to be granted with an
exercise price of no less than the Fair Market Value of the Shares.

         The term of each stock option is determined by the Committee. Awards
may, in the discretion of the Committee, be granted either alone or in addition
to, in tandem with or in substitution for any other Award granted under any plan
of the Company. The Committee determines the time or times at which an option
may be exercised in whole or in part and the method or methods by which, and the
form or forms (including, without limitation, cash, Shares, promissory notes,
other securities, other awards, or other property, or any combination thereof,
having a Fair Market Value on the exercise date equal to the relevant exercise
price) in which, payment of the exercise price with respect thereto may be made
or deemed to have been made. If the shareholders approve the amendments to the
Plan, stock options granted under the Plan will have a maximum term of 10 years.

         The Plan provides for automatic grants to non-employee directors of the
Company of (i) a Non-Qualified Stock Option to purchase 5,000 Shares upon such
person's initial election to the Board of Directors, and (ii) of a Non-Qualified
Stock Option to purchase 2,500 Shares upon such person's reelection to the
Board. Automatic grants to non-employee directors of the Company can be changed
or amended only by the Board of Directors.

         The Plan provides that the Committee may grant reload options,
separately or together with another option. Pursuant to a reload option, the
optionee would be granted a new option to purchase


                                       19


the number of Shares or such other securities or property as may become subject
to Awards, not exceeding the sum of (i) the number of Shares so provided as
consideration upon the exercise of the previously granted option to which such
reload option relates and (ii) the number of Shares, if any, tendered or
withheld as payment of the amount to be withheld under applicable tax laws in
connection with the exercise of the option to which such reload option relates
pursuant to the relevant provisions of the plan or agreement relating to such
option. Reload options have a per share exercise price equal to the Fair Market
Value of one share as of the date of grant of the new option. If the
shareholders approve the amendment to the Plan, reload options will no longer be
available for grant under the Plan.

         The holder of an SAR will be entitled to receive the excess of (i) the
Fair Market Value of one Share, on the date of exercise (or, if the Committee so
determines, at any time during a specified period before or after the date of
exercise) over (ii) the grant price of the SAR as specified by the Committee,
which price may not be less than 100% of the Fair Market Value of one Share on
the date of grant of the SAR.

         Shares of restricted stock and restricted stock units are subject to
such restrictions as the Committee may impose (including any limitations on the
right to vote or the right to receive any dividends or other right or property
related to such restricted stock and restricted stock units), which restrictions
may lapse separately or in combination at such time or times, in such
installments or otherwise as the Committee may determine. Restricted stock
granted under the Plan will be evidenced by issuance of a stock certificate,
which certificate must be registered in the name of the employee and held by the
Company. Any certificate that is no longer subject to restrictions shall be
delivered to the holder thereof promptly after the applicable restrictions lapse
or are waived. No certificates will be issued at the time restricted stock units
are granted. Upon termination of the holder's employment during the restriction
period, restricted stock and restricted stock units are forfeited and reacquired
by the Company or its affiliates, unless the Committee determines otherwise.
Upon the lapse or waiver of restrictions of restricted stock and restricted
stock units and lapse or waiver of the restricted period relating to the
restricted stock units, certificates evidencing the Shares underlying the
restricted stock or restricted stock units will be issued and delivered to their
holders. If the shareholders approve the amendments to the Plan, restricted
stock grants will no longer be available under the Plan.

         No Award (other than Other Stock Grants) and no right under any such
Award shall be transferable by a participant otherwise than by will or by the
laws of descent and distribution; provided, however, that, if so determined by
the Committee, a participant may, in the manner established by the Committee,
transfer options (other than Incentive Stock Options) or designate a beneficiary
or beneficiaries to exercise the rights of the participant and receive any
property distributable with respect to any Award upon the death of the
participant. Each Award or right under any Award is exercisable during the
participant's lifetime only by the participant or, if permissible under
applicable law, by the participant's guardian or legal representative. No Award
or right under


                                       20


any such Award may be pledged, alienated, attached or otherwise encumbered, and
any purported pledge, alienation, attachment or encumbrance thereof shall be
void and unenforceable against the Company or any affiliate.

         If any dividend or other distribution (whether in the form of cash,
Shares, other securities or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee to be
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and type of Shares (or other securities or other property) that
thereafter may be made the subject of Awards, (ii) the number and type of Shares
(or other securities or other property) subject to outstanding Awards and (iii)
the purchase or exercise price with respect to any Award.

         The Board may suspend or terminate the Plan or any portion thereof at
anytime. The Board may also amend the Plan at any time, but such action may not,
without the consent of the affected participants, adversely affect the rights or
obligations of the participants under outstanding stock options. The Board may
increase the number of shares of Common Stock that will be available for
issuance under the Plan, subject to shareholder approval. No amendment or
modification of the Plan, without approval of the shareholders of the Company,
will be effective if shareholder approval of the amendment is then required
pursuant to Rule 16b(3) under the Exchange Act or any successor rule, Section
422 of the Code, or the rules of the National Association of Securities Dealers,
Inc. Awards outstanding at the time the Plan is terminated will continue to be
exercisable in accordance with their respective terms.

                         FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of the principal federal income tax
consequences generally applicable to Awards under the Plan. The grant of an
option or SAR is not expected to result in any taxable income for the recipient.
The holder of an Incentive Stock Option generally will have no taxable income
upon exercising the Incentive Stock Option. The Company will not be entitled to
a tax deduction when an Incentive Stock Option is exercised. Upon exercising a
Non-Qualified Stock Option, the optionee must recognize ordinary income equal to
the excess of the Fair Market Value of the shares of Common Stock acquired on
the date of exercise over the exercise price, and the Company will be entitled
at that time to a tax deduction for the same amount. Upon exercising an SAR, the
amount of any cash received and the Fair Market Value on the exercise date of
any shares of Common Stock received are taxable to the recipient as ordinary
income and deductible by the Company. The tax consequence to an optionee upon a
disposition of shares acquired through the exercise of an option will depend on
how long the shares have been held and upon whether such


                                       21


shares were acquired by exercising an Incentive Stock Option or by exercising a
Non-Qualified Stock Option or SAR. Generally, there will be no tax consequence
to the Company in connection with disposition of shares acquired under an
option, except that the Company may be entitled to a tax deduction in the case
of a disposition of shares acquired under an Incentive Stock Option before the
applicable Incentive Stock Option holding periods set forth in the Code have
been satisfied.

         With respect to other Awards granted under the Plan that are payable
either in cash or shares of Common Stock that are either transferable or not
subject to substantial risk of forfeiture, the holder of such an Award must
recognize ordinary income equal to the excess of (a) the cash or the Fair Market
Value of the shares of Common Stock received (determined as of the date of such
receipt) over (b) the amount (if any) paid for such shares of Common Stock by
the holder of the award, and the Company will be entitled at that time to a
deduction for the same amount. With respect to an award that is payable in
shares of Common Stock that are restricted as to transferability and subject to
substantial risk of forfeiture, unless a special election is made pursuant to
the Code, the holder of the award must recognize ordinary income equal to the
excess of (i) the Fair Market Value of the shares of Common Stock received
(determined as of the first time the shares become transferable or not subject
to substantial risk of forfeiture, whichever occurs earlier) over (ii) the
amount (if any) paid for such shares of Common Stock by the holder, and the
Company will be entitled at that time to a tax deduction for the same amount, if
and to the extent such amount is deductible.

         Special rules may apply in the case of individuals subject to Section
16 of the Exchange Act. In particular, unless a special election is made
pursuant to the Code, shares received pursuant to the exercise of a stock option
or SAR may be treated as restricted as to transferability and subject to a
substantial risk of forfeiture for a period of up to six months after the date
of exercise. Accordingly, the amount of any ordinary income recognized, and the
amount of the Company's tax deduction, are determined as of the end of such
period.

         Under the Plan, the Committee may permit participants receiving or
exercising awards, subject to the discretion of the Committee and upon such
terms and conditions as it may impose, to satisfy certain tax obligations by (i)
electing to have the Company withhold a portion of the Shares otherwise to be
delivered upon exercise or receipt of (or the lapse of restrictions relating to)
such Award with a Fair Market Value equal to the amount of such taxes or (ii)
delivering to the Company Shares other than Shares issuable upon exercise or
receipt of (or the lapse of restrictions relating to) such Award with a Fair
Market Value equal to the amount of such taxes. The election, if any, must be
made on or before the date that the amount of tax to be withheld is determined.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE AMENDMENTS TO THE
PLAN. The affirmative vote of a majority of the outstanding shares of Common
Stock entitled to vote and present in person or by proxy at the Annual Meeting
will be required to approve the amendments. Proxies will be voted in favor of
the amendments to the Plan unless otherwise specified.

PROPOSAL 3 - PROPOSAL TO AMEND THE
ATS MEDICAL, INC. 1998 EMPLOYEE STOCK PURCHASE PLAN

         The Board of Directors has approved an amendment to the Company's 1998
Employee Stock Purchase Plan (the "Stock Purchase Plan"), subject to shareholder
approval, pursuant to which an additional 300,000 shares of Common Stock would
be reserved for purchase under the Stock Purchase Plan. The Stock Purchase Plan
was approved by the Board of Directors and the shareholders of the Company in
April 1988. The purpose of the Stock Purchase Plan is to give employees a
stronger incentive to work for the continued success of the Company by allowing
them to purchase, through payroll deductions, shares of Common Stock.

                       SUMMARY OF THE STOCK PURCHASE PLAN

         The Stock Purchase Plan provides for the purchase of shares of Common
Stock by eligible employees of the Company through payroll deductions of 1% to
10% of an employee's current compensation. The Stock Purchase Plan is intended
to qualify as an "employee stock purchase plan" under Section 423 of the Code.

         The Stock Purchase Plan is administered by the Compensation Committee,
which also interprets the Stock Purchase Plan. Employees of the Company, other
than those employees whose customary employment is less than 20 hours weekly or
who have not completed at least one month of service, are eligible to
participate in the Stock Purchase Plan. In addition, an employee who immediately
after receiving a right to purchase shares would own, directly or indirectly,
stock equal to 5% or more of the total combined voting power or value of all of
the capital stock of the Company or all of its affiliates will not be eligible
to participate in the Stock Purchase Plan. The Stock Purchase Plan will
terminate if and when all the shares of the Common Stock provided for in the
Stock Purchase Plan have been sold. Subject to the approval of this proposal by
the shareholders, the Board of Directors has reserved a total of 500,000 shares
of Common Stock for issuance under the Stock Purchase Plan, which includes the
additional 300,000 shares of Common Stock that the Board proposes to make
available for purchases under the Stock Purchase Plan.

         Under the Stock Purchase Plan, there are four three-month purchase
periods each year (each a "Purchase Period"). Purchase Periods begin on the
first business day of February, May, August and November of each calendar year
and end on the last business day of April, July, October and January,
respectively. On the last business day of each Purchase Period, each participant
receives the right to (i) purchase up to as many whole shares of Common Stock as
could be purchased with the balance in that participant's stock purchase account
as of that date, and (ii) withdraw all of the remaining accumulated payroll
deductions from such participant's account, provided that on the last day of
each Purchase Period, no cash can remain in a participant's account. The
exercise price for rights granted under the Stock Purchase Plan is the lesser of
85% of the fair market value of shares of Common


                                       23


Stock on (i) the first business day of the Purchase Period or (ii) the last
business day of the Purchase Period. No participant may purchase stock at a rate
exceeding $25,000 in fair market value of such stock (determined at the
beginning of each Purchase Period) for each calendar year under the Stock
Purchase Plan and all other stock purchase plans of the Company and its
affiliates that qualify under Section 423 of the Code.

         The Stock Purchase Plan will terminate automatically when all of the
shares of Common Stock have been sold. The Board of Directors may amend or
discontinue the Stock Purchase Plan at any time. In the absence of shareholder
approval, however, no amendment or discontinuation of the Stock Purchase Plan
shall be made that: (i) absent such shareholder approval, would cause Rule 16b-3
under the Securities Act of 1934, as amended, to become unavailable with respect
to the Stock Purchase Plan, (ii) reduces the price per share at which Common
Stock may be purchased, (iii) increases the number of shares of Common Stock
available for issuance under the Stock Purchase Plan, (iv) requires shareholder
approval under the rules or regulations of the National Association of
Securities Dealers or the Nasdaq SmallCap Market, or (v) permits the issuance of
shares of Common Stock before payment therefor in full.

                         FEDERAL INCOME TAX CONSEQUENCES

         The Stock Purchase Plan and the right of participants to make purchases
thereunder, are intended to qualify under the provisions of Sections 421 and 423
of the Code. Payroll deductions under the Stock Purchase Plan will be taxable to
a participant as compensation for the year in which such amounts would otherwise
have been paid to the participant. No income will be taxable to a participant at
the time of grant of the option or purchase of shares. A participant may become
liable for tax upon disposition of the shares acquired as summarized below.

         If the shares are sold or disposed of (including by way of gift) at
least two years after the date of the beginning of the offering period (the
"date of option grant") and at least one year after the date such shares are
purchased (the "date of option exercise"), in this event, the lesser of (a) the
excess of the fair market value of the shares at the time of such disposition
over the purchase price of the shares subject to the option (the "option price")
or (b) the excess of the fair market value of the shares at the time the option
was granted over an amount equal to what the option price would have been if it
had been computed as of the date of option grant, will be treated as ordinary
income to the participant. Any further gain upon such disposition will be
treated as capital gain. Any such capital gain would be taxed at long-term rates
if the stock is held for more than 12 months. If the shares are sold and the
sale price is less than the option price, there is no ordinary income and the
participant has a capital loss for the difference.

         In the event that the shares are sold or disposed of (including by way
of gift or by exchange in connection with the exercise of an incentive stock
option) before the expiration of the holding periods described above, the excess
of the fair market value of the shares on the date of option


                                       24


exercise over the option price will be treated as ordinary income to the
participant. This excess will constitute ordinary income in the year of sale or
other disposition even if no gain is realized on the sale or a gratuitous
transfer of the shares is made. The balance of any gain will be treated as
capital gain. Even if the shares are sold for less than their fair market value
on the date of option exercise, the same amount of ordinary income is attributed
to a participant and a capital loss is recognized equal to the difference
between the sales price and the value of the shares on such date of option
exercise. The Company ordinarily will be allowed a tax deduction at the time and
in the amount of the ordinary income recognized by the participant, but may also
be required to withhold income tax upon such amount or report such amount to the
Internal Revenue Service.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE AMENDMENT TO THE
STOCK PURCHASE PLAN. The affirmative vote of a majority of the outstanding
shares of Common Stock entitled to vote and present in person or by proxy at the
Annual Meeting will be required to approve the amendment. Proxies will be voted
in favor of the amendment to the Stock Purchase Plan unless otherwise specified.

Section 4. Shares Available for Awards.

                  (a) Shares Available. Subject to adjustment as provided in
Section 4(c) of the Plan, the aggregate number of Shares that may be issued
under all Awards under the Plan shall be 2,000,000. Shares to be issued under
the Plan may be either authorized but unissued Shares or Shares acquired in the
open market or otherwise. Any Shares that are used by a Participant as full or
partial payment to the Company of the purchase price relating to an Award, or in
connection with the satisfaction of tax obligations relating to an Award, shall
again be available for granting Awards (other than Incentive Stock Options)
under the Plan. In addition, if any Shares covered by an Award or to which an
Award relates are not purchased or are forfeited, or if an Award otherwise
terminates without delivery of any Shares, then the number of Shares counted
against the aggregate number of Shares available under the Plan with respect to
such Award, to the extent of any such forfeiture or termination, shall again be
available for granting Awards under the Plan. Notwithstanding the foregoing, the
number of Shares available for granting Incentive Stock Options under the Plan
shall not exceed 2,000,000, subject to adjustment as provided in the Plan and
subject to the provisions of Section 422 or 424 of the Code or any successor
provision.

                  (b) Accounting for Awards. For purposes of this Section 4, if
an Award entitles the holder thereof to receive or purchase Shares, the number
of Shares covered by such Award or to which such Award relates shall be counted
on the date of grant of such Award against the aggregate number of Shares
available for granting Awards under the Plan.

                  (c) Adjustments. In the event that the Committee shall
determine that any dividend or other distribution (whether in the form of cash,
Shares, other securities or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee to be
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan, then the
Committee shall, in such manner as it may deem equitable, adjust any or all of
(i) the number and type of Shares (or other securities or other property) that
thereafter may be made the subject of Awards, (ii) the number and type of Shares
(or other securities or other property) subject to outstanding Awards and (iii)
the purchase or exercise price with respect to any Award; provided, however,
that the number of Shares covered by any Award or to which such Award relates
shall always be a whole number.

                  (d) Award Limitations Under the Plan. No Eligible Person may
be granted any Award or Awards under the Plan, the value of which Award or
Awards is based solely on an increase in the value of the Shares after the date
of grant of such Award or Awards, for more


                                      -4-


than 300,000 Shares (subject to adjustment as provided for in Section 4(c) of
the Plan), in the aggregate in any calendar year. The foregoing annual
limitation specifically includes the grant of any Award or Awards representing
"qualified performance-based compensation" within the meaning of Section 162(m)
of the Code.

Section 5. Eligibility.

         Any Eligible Person shall be eligible to be designated a Participant.
In determining which Eligible Persons shall receive an Award and the terms of
any Award, the Committee may take into account the nature of the services
rendered by the respective Eligible Persons, their present and potential
contributions to the success of the Company or such other factors as the
Committee, in its discretion, shall deem relevant. Notwithstanding the
foregoing, an Incentive Stock Option may only be granted to full or part-time
employees (which term as used herein includes, without limitation, officers and
Directors who are also employees), and an Incentive Stock Option shall not be
granted to an employee of an Affiliate unless such Affiliate is also a
"subsidiary corporation" of the Company within the meaning of Section 424(f) of
the Code or any successor provision.

Section 6. Awards.

                  (a) Options. The Committee is hereby authorized to grant
Options to Participants with the following terms and conditions and with such
additional terms and conditions not inconsistent with the provisions of the Plan
as the Committee shall determine:

                           (i) Exercise Price. The purchase price per Share for
Options granted under the Plan shall be determined by the Committee; provided,
however, that such purchase price shall not be less than 100% of the Fair Market
Value of the Shares on the date of grant of such Option unless shareholder
approval is obtained.

                           (ii) Option Term. The term of each Option shall be
fixed by the Committee, but such term shall not exceed 10 years from the date on
which such Option is granted.

                           (iii) Time and Method of Exercise. The Committee
shall determine the time or times at which an Option may be exercised in whole
or in part and the method or methods by which, and the form or forms (including,
without limitation, cash, Shares, promissory notes, other securities, other
Awards or other property, or any combination thereof, having a Fair Market Value
on the exercise date equal to the relevant exercise price) in which, payment of
the exercise price with respect thereto may be made or deemed to have been made.

                  (b) Stock Appreciation Rights. The Committee is hereby
authorized to grant Stock Appreciation Rights to Participants subject to the
terms of the Plan and any applicable Award Agreement. A Stock Appreciation Right
granted under the Plan shall confer on the holder thereof a right to receive
upon exercise thereof the excess of (i) the Fair Market Value of one Share on
the date of exercise (or, if the Committee shall so determine, at any time
during a


                                      -5-


specified period before or after the date of exercise) over (ii) the grant price
of the Stock Appreciation Right as specified by the Committee, which price shall
not be less than 100% of the Fair Market Value of one Share on the date of grant
of the Stock Appreciation Right. Subject to the terms of the Plan and any
applicable Award Agreement, the grant price, term, methods of exercise, dates of
exercise, methods of settlement and any other terms and conditions of any Stock
Appreciation Right shall be as determined by the Committee. The Committee may
impose such conditions or restrictions on the exercise of any Stock Appreciation
Right as it may deem appropriate.

                  (c) Restricted Stock Units. The Committee is hereby authorized
to grant Restricted Stock Units to Participants with the following terms and
conditions and with such additional terms and conditions not inconsistent with
the provisions of the Plan as the Committee shall determine:

                           (i) Restrictions. Restricted Stock Units shall be
subject to such restrictions as the Committee may impose (including, without
limitation, a waiver by the Participant of the right to vote or to receive any
dividend or other right or property with respect thereto), which restrictions
may lapse separately or in combination at such time or times, in such
installments or otherwise as the Committee may deem appropriate.

                           (ii) Stock Certificates. No Shares shall be issued at
the time Restricted Stock Units are granted.

                           (iii) Forfeiture. Except as otherwise determined by
the Committee, upon termination of employment (as determined under criteria
established by the Committee) during the applicable restriction period, all
Restricted Stock Units at such time subject to restriction shall be forfeited
and reacquired by the Company; provided, however, that the Committee may, when
it finds that a waiver would be in the best interest of the Company, waive in
whole or in part any or all remaining restrictions with respect to Restricted
Stock Units. Upon the lapse or waiver of restrictions and the restricted period
relating to Restricted Stock Units evidencing the right to receive Shares, such
Shares shall be issued and delivered to the holders of the Restricted Stock
Units.

                  (d) Performance Awards. The Committee is hereby authorized to
grant Performance Awards to Participants subject to the terms of the Plan and
any applicable Award Agreement. A Performance Award granted under the Plan (i)
may be denominated or payable in cash, Shares (including, without limitation,
Restricted Stock Units), other securities, other Awards or other property and
(ii) shall confer on the holder thereof the right to receive payments, in whole
or in part, upon the achievement of such performance goals during such
performance periods as the Committee shall establish. Subject to the terms of
the Plan and any applicable Award Agreement, the performance goals to be
achieved during any performance period, the length of any performance period,
the amount of any Performance Award granted, the amount of any payment or
transfer to be made pursuant to any Performance Award and any other terms and
conditions of any Performance Award shall be determined by the Committee.




                                      -6-


                  (e) Other Stock Grants. The Committee is hereby authorized,
subject to the terms of the Plan and any applicable Award Agreement, to grant to
Participants Shares without restrictions thereon as are deemed by the Committee
to be consistent with the purpose of the Plan.

                  (f) Other Stock-Based Awards. The Committee is hereby
authorized to grant to Participants subject to the terms of the Plan and any
applicable Award Agreement, such other Awards that are denominated or payable
in, valued in whole or in part by reference to, or otherwise based on or related
to, Shares (including, without limitation, securities convertible into Shares),
as are deemed by the Committee to be consistent with the purpose of the Plan.
Shares or other securities delivered pursuant to a purchase right granted under
this Section 6(f) shall be purchased for such consideration, which may be paid
by such method or methods and in such form or forms (including, without
limitation, cash, Shares, promissory notes, other securities, other Awards or
other property or any combination thereof), as the Committee shall determine,
the value of which consideration, as established by the Committee, shall not be
less than 100% of the Fair Market Value of such Shares or other securities as of
the date such purchase right is granted.

                  (g) General.

                           (i) No Cash Consideration for Awards. Awards shall be
granted for no cash consideration or for such minimal cash consideration as may
be required by applicable law.

                           (ii) Awards May Be Granted Separately or Together.
Awards may, in the discretion of the Committee, be granted either alone or in
addition to, in tandem with or in substitution for any other Award or any award
granted under any plan of the Company or any Affiliate other than the Plan.
Awards granted in addition to or in tandem with other Awards or in addition to
or in tandem with awards granted under any such other plan of the Company or any
Affiliate may be granted either at the same time as or at a different time from
the grant of such other Awards or awards.

                           (iii) Forms of Payment under Awards. Subject to the
terms of the Plan and of any applicable Award Agreement, payments or transfers
to be made by the Company or an Affiliate upon the grant, exercise or payment of
an Award may be made in such form or forms as the Committee shall determine
(including, without limitation, cash, Shares, promissory notes, other
securities, other Awards or other property or any combination thereof), and may
be made in a single payment or transfer, in installments or on a deferred basis,
in each case in accordance with rules and procedures established by the
Committee. Such rules and procedures may include, without limitation, provisions
for the payment or crediting of reasonable interest on installment or deferred
payments or the grant or crediting of dividend equivalents with respect to
installment or deferred payments.

                           (iv) Limits on Transfer of Awards. No Award (other
than Other Stock Grants) and no right under any such Award shall be transferable
by a Participant otherwise than


                                      -7-


by will or by the laws of descent and distribution; provided, however, that, if
so determined by the Committee, a Participant may, in the manner established by
the Committee, transfer Options (other than Incentive Stock Options) or
designate a beneficiary or beneficiaries to exercise the rights of the
Participant and receive any property distributable with respect to any Award
upon the death of the Participant. Each Award or right under any Award shall be
exercisable during the Participant's lifetime only by the Participant or, if
permissible under applicable law, by the Participant's guardian or legal
representative. No Award or right under any such Award may be pledged,
alienated, attached or otherwise encumbered, and any purported pledge,
alienation, attachment or encumbrance thereof shall be void and unenforceable
against the Company or any Affiliate.

                           (v) Term of Awards. The term of each Award shall be
for such period as may be determined by the Committee; provided, however, that
the term of an Option shall not exceed 10 years from the date on which such
Option is granted.

                           (vi) Restrictions; Securities Exchange Listing. All
Shares or other securities delivered under the Plan pursuant to any Award or the
exercise thereof shall be subject to such restrictions as the Committee may deem
advisable under the Plan, applicable federal or state securities laws and
regulatory requirements, and the Committee may cause appropriate entries to be
made or legends to be affixed to reflect such restrictions. If any securities of
the Company are traded on a securities exchange, the Company shall not be
required to deliver any Shares or other securities covered by an Award unless
and until such Shares or other securities have been admitted for trading on such
securities exchange.

Section 7. Automatic Grants to Non-Employee Directors

         Upon such person's initial election to the Board, each director who is
not an employee or consultant to the Company shall receive a Non-Qualified Stock
Option to purchase 5,000 Shares. Thereafter, upon each re-election to the Board,
such director shall receive a Non-Qualified Stock Option to purchase 2,500
Shares. The Option shall have an exercise price equal to the Fair Market Value
of the Shares on the day of election. The Options shall have a ten year term and
shall vest in full six months following the date of grant. This Section 7 may
not be amended more than once every six months, other than to comport with
changes in the Code or the rules thereunder.

Section 8. Amendment and Termination; Adjustments.

                  (a) Amendments to the Plan. The Board may amend, alter,
suspend, discontinue or terminate the Plan at any time; provided, however, that,
notwithstanding any other provision of the Plan or any Award Agreement, without
the approval of the shareholders of the Company, no such amendment, alteration,
suspension, discontinuation or termination shall be made that, absent such
approval:

                           (i) would violate the rules or regulations of the
NASDAQ National Market System or any securities exchange that are applicable to
the Company; or




                                      -8-


                           (ii) would cause the Company to be unable, under the
Code, to grant Incentive Stock Options under the Plan.

                  (b) Amendments to Awards. Except for Awards granted pursuant
to Section 7, the Committee may waive any conditions of or rights of the Company
under any outstanding Award, prospectively or retroactively. Except as otherwise
provided herein or in the Award Agreement, the Committee may not amend, alter,
suspend, discontinue or terminate any outstanding Award, prospectively or
retroactively, if such action would adversely affect the rights of the holder of
such Award, without the consent of the Participant or holder or beneficiary
thereof.

                  (c) Prohibition on Option Repricing. The Committee shall not
reduce the exercise price of any outstanding Option, whether through amendment,
cancellation or replacement grants, or any other means, without shareholder
approval.

                  (d) Correction of Defects, Omissions and Inconsistencies. The
Committee may correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Award in the manner and to the extent it shall
deem desirable to carry the Plan into effect.

Section 9. Income Tax Withholding; Tax Bonuses.

                  (a) Withholding. In order to comply with all applicable
federal or state income tax laws or regulations, the Company may take such
action as it deems appropriate to ensure that all applicable federal or state
payroll, withholding, income or other taxes, which are the sole and absolute
responsibility of a Participant, are withheld or collected from such
Participant. In order to assist a Participant in paying all or a portion of the
federal and state taxes to be withheld or collected upon exercise or receipt of
(or the lapse of restrictions relating to) an Award, the Committee, in its
discretion and subject to such additional terms and conditions as it may adopt,
may permit the Participant to satisfy such tax obligation by (i) electing to
have the Company withhold a portion of the Shares otherwise to be delivered upon
exercise or receipt of (or the lapse of restrictions relating to) such Award
with a Fair Market Value equal to the amount of such taxes or (ii) delivering to
the Company Shares other than Shares issuable upon exercise or receipt of (or
the lapse of restrictions relating to) such Award with a Fair Market Value equal
to the amount of such taxes. The election, if any, must be made on or before the
date that the amount of tax to be withheld is determined.

                  (b) Tax Bonuses. The Committee, in its discretion, shall have
the authority, at the time of grant of any Award under this Plan or at any time
thereafter, to approve cash bonuses to designated Participants to be paid upon
their exercise or receipt of (or the lapse of restrictions relating to) Awards
in order to provide funds to pay all or a portion of federal and state taxes due
as a result of such exercise or receipt (or the lapse of such restrictions). The
Committee shall have full authority in its discretion to determine the amount of
any such tax bonus.






                                      -9-


Section 10. General Provisions.

                  (a) No Rights to Awards. No Eligible Person, Participant or
other Person shall have any claim to be granted any Award under the Plan, and
there is no obligation for uniformity of treatment of Eligible Persons,
Participants or holders or beneficiaries of Awards under the Plan. The terms and
conditions of Awards need not be the same with respect to any Participant or
with respect to different Participants.

                  (b) Award Agreements. No Participant will have rights under an
Award granted to such Participant unless and until an Award Agreement shall have
been duly executed on behalf of the Company and, if requested by the Company,
signed by the Participant.

                  (c) No Limit on Other Compensation Arrangements. Nothing
contained in the Plan shall prevent the Company or any Affiliate from adopting
or continuing in effect other or additional compensation arrangements, and such
arrangements may be either generally applicable or applicable only in specific
cases.

                  (d) No Right to Employment. The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Affiliate, nor will it affect in any way the right of the Company
or an Affiliate to terminate such employment at any time, with or without cause.
In addition, the Company or an Affiliate may at any time dismiss a Participant
from employment free from any liability or any claim under the Plan or any
Award, unless otherwise expressly provided in the Plan or in any Award
Agreement.

                  (e) Governing Law. The validity, construction and effect of
the Plan or any Award, and any rules and regulations relating to the Plan or any
Award, shall be determined in accordance with the laws of the State of
Minnesota.

                  (f) Severability. If any provision of the Plan or any Award is
or becomes or is deemed to be invalid, illegal or unenforceable in any
jurisdiction or would disqualify the Plan or any Award under any law deemed
applicable by the Committee, such provision shall be construed or deemed amended
to conform to applicable laws, or if it cannot be so construed or deemed amended
without, in the determination of the Committee, materially altering the purpose
or intent of the Plan or the Award, such provision shall be stricken as to such
jurisdiction or Award, and the remainder of the Plan or any such Award shall
remain in full force and effect.

                  (g) No Trust or Fund Created. Neither the Plan nor any Award
shall create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Affiliate and a Participant or
any other Person. To the extent that any Person acquires a right to receive
payments from the Company or any Affiliate pursuant to an Award, such right
shall be no greater than the right of any unsecured general creditor of the
Company or any Affiliate.

                  (h) No Fractional Shares. No fractional Shares shall be issued
or delivered pursuant to the Plan or any Award, and the Committee shall
determine whether cash shall be



                                      -10-


paid in lieu of any fractional Shares or whether such fractional Shares or any
rights thereto shall be canceled, terminated or otherwise eliminated.

                  (i) Headings. Headings are given to the Sections and
subsections of the Plan solely as a convenience to facilitate reference. Such
headings shall not be deemed in any way material or relevant to the construction
or interpretation of the Plan or any provision thereof.

Section 11. Effective Date of the Plan.

         The Plan shall be effective when first approved by the shareholders of
the Company.

Section 12. Term of the Plan.

         No Award shall be granted under the Plan after December 31, 2010 or any
earlier date of discontinuation or termination established pursuant to Section
8(a) of the Plan. However, unless otherwise expressly provided in the Plan or in
an applicable Award Agreement, any Award theretofore granted may extend beyond
such date.
