Report of Independent Accountants

To
the Participants and Administrator
of the Minntech Corporation
Profit Sharing and Retirement Plan and Trust:

In
our opinion, the accompanying statement of net assets available for benefits and the related statement of changes in net assets available for benefits present fairly, in all material respects, the
net assets available for benefits of the Minntech Corporation Profit Sharing and Retirement Plan and Trust (the Plan) at March 31, 2000 and 1999, and the changes in net assets available for benefits
for the year ended March 31, 2000 in conformity with accounting principles generally accepted in the United States. These financial statements are the responsibility of the Plan's management; our
responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the
United States, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above.

Our
audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes is presented for
purposes of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting
and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the
auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a
whole.

Minntech Corporation

Profit Sharing and Retirement Plan and Trust

Notes to Financial Statements

1. Description of the Plan

The following description of the Minntech Corporation Profit Sharing and Retirement Plan and Trust (the Plan) provides only general information. Participants
should refer to the Plan agreement for a more complete description of the Plan's provisions.



The Plan is a defined contribution plan covering all eligible Minntech Corporation (the Company) employees. Employees are eligible to participate in the Plan
after the employee has completed 1,000 or more hours of service during 12 consecutive months. Certain employees are not eligible if employed under a collective bargaining agreement with a labor union
unless that agreement expressly provides for the employee's coverage under the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).



DCA is the Plan Administrator. Schwab Institutional is the trustee of the Plan.



Eligible participants may contribute 1% to 10% of pre-tax annual compensation, as defined by the Plan. The Company contributes 10% of the first 6% of base
compensation that a participant contributes to the Plan. Participants may also contribute amounts representing distributions from other qualified defined benefit or contribution plans.

Additional
amounts may be contributed to the Plan each year based upon the financial performance of the Company at the option of the Company's Board of Directors. The Company is not
required to make a discretionary contribution in any Plan year. Contributions are subject to certain limitations.



Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and, (b) Plan earnings, and
charged with an allocation of administrative expenses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that
can be provided from the participant's vested account.



Participants are immediately vested in their contributions plus actual earnings thereon. Vesting in the Company's matching and discretionary contribution
portion of their accounts plus actual earnings thereon is based upon years of continuous service. A participant vests twenty percent after three years, an additional twenty percent for each years
four, five, six, and seven. A participant is fully vested after seven years of service or upon retirement at age sixty-five or upon death or disability.

Upon enrollment in the Plan, a participant may direct employee contributions in 5% increments in any of 12 investment options. Eleven of the 12 investment
options existing at March 31, 2000 are through Fidelity Investments. The remaining investment option includes a fund invested primarily in shares of the Company's common stock. Participants may change
their investment options at any time.



Participants may borrow from their account balance a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50% of their vested account balance.
Loan transactions are treated as a transfer to (from) the investment fund from (to) the participant loan fund. The loans are secured by the vested balance in the participants' accounts and bear
interest at the prime interest rate. Principal and interest is paid ratably through monthly payroll deductions. Loan terms range from one to five years or up to ten years for the purchase of a primary
residence.



Upon termination of service, a participant elect to receive either a lump-sum amount equal to the value of the participant's vested balance in his or her
account, or annual or more frequent installments of as nearly equal amounts as may be conveniently determined, but in no event less than the minimum distribution required under Internal Revenue Code
(IRC) Section 401(a)(9).



When employment ends, the participants are vested in all, some or none of their account balance, depending upon various factors, including the participant's
age and length of service. Any non-vested portion of the account balance will be forfeited. Forfeitures of terminated participants are allocated first to restore any forfeitures of re-employed
participants and then are allocated to the accounts of eligible participants based upon the ratio of the individual participant's compensation for the Plan year over the compensation of all eligible
participants for the Plan year. At March 31, 2000, forfeited nonvested accounts totaled $37,318.

2. Significant Accounting Policies



The financial statements of the Plan are prepared under the accrual method of accounting.



The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities and changes therein, disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

F-5

---



The Plan's investments are stated at fair value. Quoted market prices are used to value investments. Shares of mutual funds are valued at the net asset value
of shares held by the Plan at year-end. Participant loans are valued at cost which approximates fair value.

Purchases
and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.



Benefits are recorded when paid.



Administrative expenses paid by the Plan for the years ended March 31, 2000 and 1999 were $34,534 and $36,658, respectively. Administrative expenses for legal,
auditing, and administration costs have been fully paid by the Company at its discretion.



The Plan provides for various investment options in any combination of stocks, bonds and other investment securities. Investment securities are exposed to
various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of
investment securities, it is at least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the Statement of Net
Assets Available for Benefits and the Statement of Changes in Net Assets Available for Benefits.



Although it has no intentions to do so, the Company may elect to terminate the Plan at any time, by action of its Board of Directors. In the event the Company
elects to terminate the Plan, all participant account balances become fully vested.



On September 15, 1999, the Accounting Standards Executive Committee of the American Institute of Certified Public Accountants issued Statement of Position
(SOP) 99-3, 'Accounting for and Reporting of Certain Defined Contribution Benefit Investments and Other Disclosure Matters.' SOP 99-3 is effective for financial statements of plan years ending after
December 15, 1999, with earlier adoption encouraged. The SOP 99-3 revised the requirements for disclosure of separate fund information for individual investment options and other investment related
disclosure, but had no effect on net assets available for plan benefits. The Plan adopted such requirements for the year ended March 31, 2000.

value as follows:

|             |  | $ | 2,209,169
|             |  |   |          

4. Tax Status

The Internal Revenue Service has determined and informed the Company by letter dated November 30, 1993 that the Plan qualifies under the applicable sections of
the Internal Revenue Code (IRC) and is, therefore, not subject to tax under present income tax law. The Plan has been amended since receiving the determination letter. However, the Plan administrator
and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable provisions of the IRC.

5. Related Party and Party-in-Interest Transactions

Plan investments include shares of the Company's common stock. The Company is the holding company of the Plan sponsor and therefore, these investment
transactions qualify as party-in-interest. Purchases and sales of Minntech Corporation common stock for the year ended March 31, 2000 amounted to $414,242 and $333,069, respectively.
