and the Company have agreed to a full settlement of all issues potentially in dispute between them.

4.Payments.In consideration of McGoldrick's past services to the Company as a
director, employee, and officer of the Company and his agreements to continue to render services to the Company as a consultant and not to enter into competition with the Company as provided in this
Agreement, the Company will make the payments set forth in subparagraph 4.a. below to McGoldrick or for his benefit, but only if (i) McGoldrick has not rescinded this Agreement or the
McGoldrick Release within the applicable rescission period; and (ii) the Company has received written confirmation from McGoldrick, in the form attached to this Agreement as Exhibit C,
dated not earlier than the day after the expiration of the applicable rescission period, that McGoldrick has not rescinded and will not rescind this Agreement or the McGoldrick Release. Payment of any

5.Stock Options.(a) McGoldrick is a participant in the Company's 1989
and 1998 Stock Option Plans (the "Stock Plans"). Under the terms of the Stock Plans and McGoldrick's agreements relating to options to purchase shares of the Company's common stock (the "Option
Agreements"), as of July 7, 2000 McGoldrick is fully vested in options to purchase a total of 217,000 shares of the common stock of the Company, which are listed in Schedule 1 attached
to this Agreement (the "Stock Options"). McGoldrick understands that if he does not exercise his incentive stock options to purchase 47,562 shares of common stock of the Company (the "47,562 Shares")
on or before October 7, 2000, then the 47,562 Shares will become nonqualified stock options. McGoldrick also understands that options to purchase 30,000 shares of the common stock of the
Company (the "30,000 Shares") must be exercised on or before April 2, 2001 as set forth in the attached Schedule 1; if he does not exercise the 30,000 Shares by that date, then the
30,000 Shares will lapse. All other remaining options (187,000 shares) shall be exercisable during the term of this Agreement until the end of the business day on July 7, 2001, thus extending
the period to exercise such options under the Option Agreements in respect thereof by an additional nine-month period.

followed to comply with McGoldrick's written instructions with respect to his stock options, retirement benefits, and health and life insurance benefits, and will provide him with information that he
reasonably requires in accordance with the applicable employee benefit plans sponsored by the Company in which he is a participant.

10.Indemnification.Notwithstanding McGoldrick's separation from the Company,
with respect to events that occurred during his tenure as an employee or officer of the Company, McGoldrick will be entitled, as a former employee or officer of the Company, to the same rights that
are afforded to senior executive officers of the Company, now or in the future, to indemnification and advancement of expenses provided in the charter documents of the Company and under applicable law
or otherwise, and to coverage and a legal defense under any applicable general liability and/or directors' and officers' liability insurance policies maintained by the Company.

12.Company Representation.The Company represents that on the date of this
Agreement no transaction or other event has occurred that would constitute a "Change in Control" as that term is defined in the Management Agreement dated September 1, 1996 between McGoldrick
and the Company. McGoldrick acknowledges that he will be relinquishing his rights under the Management Agreement upon execution of this Agreement and the McGoldrick Release of Claims.

13.Standstill.McGoldrick agrees that during the Standstill Period (as
hereinafter defined), McGoldrick and his affiliates [as such term is defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the "Exchange
Act")] will not (and he and they will not assist or encourage others to), directly or indirectly:



As
used herein, the Standstill Period means the period commencing as of the date hereof and terminating one year from the date hereof. McGoldrick covenants that as of the date hereof neither he nor

15.Claims and Actions Involving the Company.During the period commencing on
the Effective Date and ending two years from the Effective Date, McGoldrick will not recommend or suggest to any potential claimants or plaintiffs or their attorneys or agents that they initiate

with any claimants or plaintiffs or their attorneys or agents in any claims or lawsuits now pending or commenced in the future against the Company, any of its affiliates or divisions, or any of its or
their directors, officers, employees, or agents; provided, however, that this paragraph will not be interpreted or construed to prevent McGoldrick from giving testimony in response to questions asked

not constitute an admission that the Company has violated any local ordinance, state or federal statute, or principle of common law, or that the Company has engaged in any improper or unlawful conduct

enter into this Agreement and the McGoldrick Release, and that no causes of action, claims, or demands released pursuant to this Agreement and the McGoldrick Release have been assigned to any person

to consider this Agreement and the McGoldrick Release, that he has had a full opportunity to ask any questions that he may have concerning this Agreement, the McGoldrick Release, or the settlement of

but will not be assignable by either party without the prior written consent of the other party.

25.Invalidity.In the event that any provision of this Agreement, the
McGoldrick Release, or the Minntech Release is determined by a court of competent jurisdiction to be invalid, illegal, or unenforceable in any respect, such a determination will not affect the
validity, legality, or enforceability of the remaining provisions of this Agreement, the McGoldrick Release, or the Minntech Release, and the remaining provisions of this Agreement, the McGoldrick
Release, and the Minntech Release will
continue to be valid and enforceable, and any court of competent jurisdiction may modify the objectionable provision so as to make it valid and enforceable.

26.Entire Agreement.Before signing this Agreement, the McGoldrick Release,
and the Minntech Release, the parties and their representatives engaged in discussions and negotiations and generated certain documents, in which the parties and their representative considered the
matters that are the subject of this Agreement, the McGoldrick Release, and the Minntech Release. In such discussions, negotiations, and documents, the parties and their representatives may have
expressed their opinions and beliefs concerning the intentions, capabilities, and practices of the parties, and may have forecast future events. The parties recognize, however, that all business
transactions, including the transactions upon which the parties' respective opinions, beliefs, and forecasts are based, contain an element of risk, and that it is normal business practice to limit the
legal obligations of contracting parties only to those promises and representations that are essential to the transaction so as to provide certainty as to their

Agreement), the Retirement Plans, and any other employee benefit plans sponsored by the Company in which McGoldrick is a participant are intended to define the full extent of the legally enforceable
undertakings of the parties, and no promises or representations, written or oral, that are not set forth explicitly in this Agreement, the McGoldrick Release, the Minntech Release, the Stock Plans and
McGoldrick's agreements relating thereto (as modified by this Agreement), the Retirement Plans, or any other employee benefit plans sponsored by the Company in which McGoldrick is a participant are
intended by either party to be legally binding, and all other agreements and understandings between the parties are hereby superseded.

27.Headings.The descriptive headings of the paragraphs and subparagraphs of
this Agreement are inserted for convenience only, and do not constitute a part of this Agreement.

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

29.Governing Law.This Agreement, the McGoldrick Release, and the Minntech
Release will be interpreted and construed in accordance with, and any dispute or controversy arising from any breach or asserted breach of this Agreement, the McGoldrick Release, or the Minntech
Release will be governed by, the laws of Minnesota.

30.Outplacement Services.The Company shall pay directly to Lee Hecht Harrison
an amount equal to $15,000 for outplacement services for McGoldrick.

IN
WITNESS WHEREOF, the parties have executed this Agreement on the date first written above.
