                                     PART I

ITEM 1.  BUSINESS
GENERAL DEVELOPMENT OF THE BUSINESS

Minntech Corporation (the "Company") was incorporated on January 30, 1974 under
the laws of Minnesota.  The Company is engaged in the development, manufacturing
and marketing of medical supplies and devices, sterilants and water filtration
products.  The Company's products are used primarily in kidney dialysis and in
open-heart surgery.  The trade name of Renal Systems is used for products sold
in the dialysis market, the trade name of Minntech is used for products sold in
the cardiosurgery market, and the trade name of Fibercor is used for marketing
water filtration products.  The Company has core technologies in electronics,
fibers, plastics, and chemical solutions, all of which were internally
developed.

INDUSTRY SEGMENTS

Through March 31, 1995, the Company has been engaged in a single industry
segment -- medical devices and supplies.  The Company also markets filtration
devices for industrial water purification applications.  Through March 31, 1995,
sales revenues from such devices have not been material.

PRODUCTS

The Company has four interrelated product groups:

          -    Dialysis Supplies and Devices
          -    Reprocessing Products
          -    Cardiosurgery Products
          -    Water Filtration Products

     DIALYSIS SUPPLIES AND DEVICES

The Company's main dialysis supply product is a line of concentrates used by
kidney centers to prepare dialysate (a salt solution) for hemodialysis
treatments. The Company provides the industry's most complete line of these
concentrates in both liquid and powder forms for use in virtually all types of
kidney dialysis machines.  Sales of concentrate products accounted for more than
70% of all sales in this product group in each of the past three fiscal years.

The Company in fiscal 1992 introduced its first dialyzer (artificial kidney) -
the Renaflo -Registered Trademark- HDF1350 dialyzer.  In fiscal 1993, the
Company introduced the Primus -Registered Trademark- line of second generation
dialyzers in Europe.  In August 1994, the Company received FDA market clearance
to sell the Primus -Registered Trademark- dialyzer in the United States.  These
dialyzer products contain the Company's proprietary high flux polysulfone
membrane, and the Company is one of only three manufacturers of such polysulfone
devices in the world. High flux dialyzers allow for more rapid dialysis, are
capable of shortening patient treatment time, and are less traumatic to blood
than dialyzers containing traditional membranes. Dialyzers are the single most
expensive supply item used in hemodialysis treatments.  The worldwide annual
market for high flux types of dialyzers is estimated to be approximately $180
million.  (Market size is based on published information on patient populations
and the Company's estimate of the percentage of treatments performed with high
flux dialyzers.)  The Company's market share at March 31, 1995 was less than one
percent.

The Company's major dialysis electronic products are the Sonalarm-Registered
Trademark- Foam Detector, a device that detects air in blood during
hemodialysis, the Minipump -TM- Hemodialysis Blood Pump which

                                       -1-

                                                                    Page 2 of 53
<PAGE>


circulates blood during hemodialysis, and a peritoneal dialysis pump. The
Sonalarm-Registered Trademark- and the Minipump-TM- are sold to end users and in
component form to other manufacturers of blood processing equipment.  The
peritoneal pump is sold as an OEM component to another manufacturer.

In 1992, the Company entered into an agreement with Akzo Faser AG (now AKZO
Nobel Faser AG ("Akzo")) to supply its Polyphen-TM- hollow fiber dialyzer
membrane on an exclusive basis.  Under the agreement, Akzo was obligated to
purchase certain minimum quantities of fiber over five years from 1992 to 1997.
In 1995, the Company and Akzo terminated this agreement and concluded an
arrangement allowing Akzo to purchase fiber on a non-exclusive basis without
minimum requirements.  This new arrangement allows the Company to sell fiber (or
dialyzers containing this fiber) to any other customers worldwide.  Sales to
Akzo in fiscal 1995 amounted to approximately $1,170,000.  In fiscal years 1994
and 1993, sales under the agreement totaled $654,000 and $450,000, respectively.

These dialysis products accounted for approximately 33% of product sales in
fiscal 1995, 34% of product sales in fiscal 1994 and 27% of product sales in
fiscal 1993.

      REPROCESSING PRODUCTS

Reprocessing products include the Renatron -Registered Trademark- Dialyzer
Reprocessing System and associated supplies including Renalin -Registered
Trademark-, a cold sterilant solution which replaces formaldehyde in dialyzer
reprocessing, and Actril -Registered Trademark- Cold Sterilant, a kidney machine
disinfectant.

In response to government-mandated cost containment measures, many U.S. dialysis
centers in the late 1970s began reusing dialyzers (artificial kidneys) instead
of discarding them after a single use. In 1982, the Company introduced the
Renatron -Registered Trademark-,  a machine that provides an automated method of
rinsing, cleaning, testing, and sterilizing dialyzers for multiple reuse. In
1985 dialysis centers began using Renalin -Registered Trademark- sterilant for
manual reprocessing of dialyzers. In 1990, the Company began sales of the
Renatron -Registered Trademark- II, a second generation system that includes a
bar code reader, computer and Renalog -Registered Trademark- software for
automated record keeping and analysis. Recent data released by the Centers for
Disease Control ("CDC") indicate that, as of 1993, 79% of all U.S. hemodialysis
patients were treated in centers that reuse dialyzers.  The CDC also reported
that 73% of all dialysis centers in the United States  reuse dialyzers and 51%
of these centers used Renalin -Registered Trademark- to sterilize their
dialyzers.  The other dialysis centers used primarily formaldehyde or
glutaraldehyde disinfectants to reprocess dialyzers.

The Company believes its Renatron -Registered Trademark- system is faster and
easier to use than competitive automated systems. The Company also believes that
the Renatron -Registered Trademark- system is the top selling automated dialyzer
reprocessing system in the world.  At March 31, 1995, the Company had an
installed customer base of more than 2,000 Renatron -Registered Trademark-
systems.

During fiscal 1994, the Company completed the purchase of a sterilant product
line from a German firm as part of its strategy of geographic expansion of its
reprocessing business.  Unlike the United States market, dialyzer reuse is in
the formative stages in Europe.  The Company has increased its reprocessing
product sales in Europe by employing direct salespersons in major dialysis
markets and promoting the advantages of reuse.

In September 1994, the Company purchased an endoscope reprocessor product line
from Bard Interventional Products, a division of C.R. Bard, Inc. for $934,000 in
cash.  Manufacturing of the products was assimilated into the Company's
electronic device production facility in Plymouth, Minnesota.  The endoscope
reprocessing machine provides high level disinfection for flexible endoscopes
and is marketed to gastroenterology units of hospitals and ambulatory care
units.

                                       -2-
                                                                    Page 3 of 53
<PAGE>


The Company began sales of the Cathetron-Registered Trademark- Reprocessing
System in Europe in April 1994.  The Cathetron-Registered Trademark- System,
along with its companion cold sterilant CATHx-Registered Trademark-, provides an
automated method of cleaning and sterilizing cardiovascular catheters for
subsequent reuse.  At  March 31, 1995, the Company remained in the early stages
of marketing the Cathetron-Registered Trademark-  System in Europe and certain
other international markets.  The Company plans to submit an Investigational
Device Exemption application to the FDA in fiscal 1996 so that clinical trials
can be conducted in the United States.

Reprocessing products accounted for approximately 32% of product sales in fiscal
1995 and 28% of product sales in fiscal years 1994 and 1993.

     CARDIOSURGERY PRODUCTS

The primary products in this group at March 31, 1995 consisted of three hollow
fiber devices.

     OXYGENATORS

Since 1987 the Company has manufactured a hollow-fiber membrane oxygenator for
use in open-heart surgery. The device contains a highly efficient, integrated
heat exchanger, and the Company believes that the unit is capable of
transferring more oxygen than competitive products. Since 1987, the Company has
manufactured the oxygenator for exclusive worldwide distribution pursuant to an
agreement with C.R. Bard, Inc. ("Bard")  Bard agreed to purchase certain minimum
quantities of the oxygenator through December 31, 1995.  These minimum
quantities had an annual sales value to the Company of approximately $10
million, and Bard's annual purchases through March 31, 1995 exceeded such
minimums.


Bard and the Company in April 1995 entered into a new agreement for the sale of
the oxygenator whereby Bard has agreed to purchase certain minimum quantities of
the oxygenator through March 31, 1997, but the agreement also allows Bard to
continue purchasing the oxygenator through June 30, 1997, without any minimum
purchase obligation.  Bard will have exclusive distribution rights through March
31, 1997 and nonexclusive rights thereafter.  Bard's minimum purchase obligation
under the agreement for the period April 1, 1995 to March 31, 1997 has a sales
value to the Company of approximately $20 million.  The agreement restricts Bard
from selling any other oxygenator until January 1, 1997, but permits the Company
to begin worldwide sales of its second generation oxygenator whenever it becomes
commercially available.  See "Significant Customers."

The Company is developing a second generation oxygenator that requires less
priming volume while improving the performance over its existing product.  The
device incorporates the Company's proprietary weaving technology for the
membrane oxygenation compartment and heat exchange compartment.  At March 31,
1995, the product was in the final stages of development.

     HEMOCONCENTRATORS

Since 1985, the Company has manufactured and sold hemoconcentrators, a
filtration device that removes excess body fluids during open-heart surgery. In
1988, the Company introduced a second generation product, the Hemocor Plus -
Registered Trademark- hemoconcentrator, a rinse-free device that allows for
faster set-up during surgery.  In February 1994, the Company received FDA market
clearance for a third generation product, the Hemocor HPH -Registered Trademark-
line which contains a higher performance hollow fiber membrane.  The Company
estimates that hemoconcentration is currently used in 25% of all open-heart
procedures in the United States and to a lesser extent internationally and that
such procedures require up to 125,000 hemoconcentrator devices annually
worldwide. At March 31, 1995, the Company held more than a 50% share of the
United States hemoconcentrator market.

                                                                    Page 4 of 53
<PAGE>


     HEMOFILTERS

The Renaflo-Registered Trademark- Hemofilter, introduced in 1985, is a device
that performs continuous arteriovenous hemofiltration (CAVH), an intensive care
therapy that treats acute renal failure and fluid overload in critically ill
patients.  CAVH is an alternative to conventional dialysis for these patients.

Cardiosurgery products accounted for approximately 33% of product sales in
fiscal 1995, 37% of product sales in fiscal 1994, and 44% of product sales in
fiscal 1993.

In April 1995, the Company completed the acquisition of the hemoconcentrator,
hemofilter and dialysate filter product lines from Amicon Ireland Ltd, an
indirect subsidiary of W.R. Grace & Co. ("Amicon").  The purchase price was
approximately $1.4 million, paid in cash.  These products are expected to
generate approximately $4 million in sales in the first year.  The Company also
signed a six-month supply agreement with Amicon whereby Amicon will contract
manufacture products for the Company to be sold in Europe.  During this six-
month period, the Company expects to transfer manufacturing to its U.S.
facility.

     WATER FILTRATION PRODUCTS

There are two major products in this group:   Fiberflo -Registered Trademark-
Microfilters and Minncare -Registered Trademark- Disinfectant.    The Fiberflo -
Registered Trademark- Microfilter is a hollow fiber filter that has "point of
use" applications in industrial water purification.  These filters are being
used for finer filtration in the pharmaceutical, medical device, and
biotechnology industries.  Minncare -Registered Trademark- Disinfectant is used
to disinfect water treatment systems.  Through March 31, 1995, water filtration
products sales revenues have not been material, accounting for approximately 1%
of product sales in fiscal 1994 and 2% of product sales in fiscal 1995.

MARKETS AND DISTRIBUTION

The Company sells its medical products in the United States primarily to
hospitals, clinics, and kidney treatment centers. The Company markets these
products in the United States through direct sales forces and through
independent stocking distributors. At March 31, 1995, the Company employed a
total of eight dialysis sales representatives in the United States, two
cardiosurgery sales representatives, two water filtration sales representatives,
and one endoscope reprocessor sales representative. In addition, a customer
service staff and a technical services department support field activity. The
Company also operates its own trucks to expedite delivery of certain products
and minimize shipping costs.

Until 1991, the Company had historically marketed its products internationally
through independent distributors.  Starting in 1991, the Company began
establishing direct sales operations in Europe to enhance marketing of its
products.  The Company's goal is to increase its revenues in Europe through
expanded direct sales activities.  The Company recently established a
headquarters for its European operations in the Netherlands and employed a total
of 11 people in Europe at March 31, 1995.

The Company's dialysis marketing programs are directed at nephrologists (doctors
who specialize in treating kidney disease), nurses, hospital and clinic
administrators, and others who influence purchasing decisions.  Cardiosurgery
marketing programs are directed at perfusionists (technicians who operate heart-
lung bypass equipment) and cardiovascular surgeons. The Company supports its
field organization and network of distributors through advertising, distribution
of sales materials, publication of articles in medical journals, and attendance
at medical conferences.

                                                                    Page 5 of 53
<PAGE>


NEW PRODUCTS

In July 1992, the Company submitted premarket notification to the FDA for
clearance of the Primus -Registered Trademark- series of dialyzers which utilize
the Company's internally developed polysulfone hollow fiber membrane.   FDA
market clearance was finally received in August 1994, following a two-year
review cycle, and the Company commenced direct sales of the Primus -Registered
Trademark- dialyzer in the United States in September.

During fiscal 1995, the Company continued development of a second generation
membrane oxygenator and associated products, including venous blood reservoirs.
The new oxygenator is intended to replace the Company's existing oxygenator.
The new oxygenator is smaller in size, requires less priming volume and is
intended to have improved performance compared to the existing product.  The
Company expects to complete development of these products in fiscal 1996, obtain
necessary market clearances, and commence sales.

SOURCES AND AVAILABILITY OF MATERIALS

The majority of the materials and components that the Company uses in its
manufacturing operations are readily obtainable from multiple sources worldwide.
In addition, the Company constructs many of its injection molds and also molds
and extrudes many of its component plastic parts.

PATENTS AND TRADEMARKS

The Company holds rights under 81 patents worldwide (including 32 U.S. patents)
covering its products or components thereof. At March 31, 1995, the Company also
had a total of 93 pending patent applications in the United States and in
foreign countries. The Company also holds rights under 114 trademark
registrations worldwide and has 75 applications pending.

The Company believes that patent protection is a significant factor in
maintaining its market position but the rapid changes of technology in kidney
dialysis therapy, cardiosurgery, and the other areas in which the Company
competes may limit the value of the Company's existing patents.

While patents have a presumption of validity under the law, the issuance of a
patent is not conclusive as to its validity or the enforceable scope of its
claims.  Accordingly, there can be no assurance that the Company's existing
patents will afford protection against competitors with similar inventions nor
can there be any assurance that the Company's patents will not be infringed.
Competitors also may obtain patents that the Company would need to license or
design around.  These factors also tend to limit the value of the Company's
existing patents.  Consequently, in certain instances, the Company may consider
trade secret protection to be a more effective method of maintaining its
proprietary positions.

SEASONALITY OF THE BUSINESS

The Company's business is not seasonal.

WORKING CAPITAL AND BACKLOG

The Company's credit practices and related working capital needs are comparable
to those of other companies in the medical device and supplies industry. The
Company generally fills orders within 30 days of receipt. No material order
backlogs existed at March 31, 1994.  An order backlog existed for
hemoconcentrators, dialyzers and water filters at March 31, 1995.  This backlog
had an estimated aggregate sales value of $600,000, and the Company expects to
fill these orders in fiscal 1996.

                                       -5-
                                                                    Page 6 of 53
<PAGE>


SIGNIFICANT CUSTOMERS

The Company's five largest customers in fiscal 1995 accounted for approximately
40% of total product sales.  Sales of oxygenators to C.R. Bard, Inc. ("Bard")
accounted for 25% or more of product sales in fiscal years 1995, 1994 and 1993.
Bard agreed to purchase certain minimum quantities of the oxygenator under a
contract that began in fiscal 1988 and was scheduled to terminate December 31,
1995.  In April 1995, a new agreement was reached extending the term to
June 30, 1997.  The loss of Bard as a customer would likely have a material
adverse effect upon the Company's business if the Company was unable to
successfully market the oxygenator (or successor products) itself or to arrange
for other means of distribution.  See "Oxygenators" under "Products."

RENEGOTIATION OR TERMINATION OF GOVERNMENT CONTRACTS

No material portion of the Company's business is subject to renegotiation of
profits or termination of contracts or subcontracts at the election of the
Government.

COMPETITION AND MARKET CONDITIONS

The Company's dialysis and reprocessing products are sold in a highly
competitive market, and the Company competes with many other firms. The dialysis
market is dominated by a few firms including Baxter International, Gambro AB
(CGH Medical), W.R. Grace & Co. (National Medical Care), and Fresenius AG.
These firms have substantially greater financial and personnel resources than
the Company and most of them produce and sell a more comprehensive line of
dialysis equipment and supplies. The Company also faces competition from other
international companies and several smaller companies that carry a limited line
of products.

The Company's membrane oxygenator is sold exclusively by Bard Cardiopulmonary
Division of C.R. Bard, Inc. ("Bard") Bard's major competitors are Medtronic,
Inc., CGH Medical, Bentley Laboratories, Inc., Terumo Corporation and Avecor
Cardiovascular, Inc. The Company's hemoconcentrators are sold by its own direct
sales force and by a network of independent medical distributors. The major
competitors in the hemoconcentrator market are CGH Medical, C.R. Bard, Inc., and
Bentley Laboratories, Inc.

The health care industry in the United States operates under cost containment
pressures imposed by the federal government, employers, and health insurance
carriers. One major influence is the Medicare Prospective Payment System,
implemented in 1983, which provides for fixed payments to hospitals for care of
Medicare patients based on diagnosis rather than actual hospital charges (the
DRG system). In addition, the Company's end user customers for its dialysis and
reprocessing products are subject to fixed payments per treatment under separate
Medicare regulations which have been in place for more than 20 years.

Health care providers, in general, have responded by shortening hospital stays
through quicker clinical diagnoses and by employing less invasive medical
procedures and more efficient therapies. In addition, hospitals and other health
care providers have sought to lower their costs by reducing their purchased
supplies costs and by improving their utilization of facilities and equipment.
Dialysis centers, in particular, have also responded by reprocessing and reusing
dialyzers and other supplies and by shortening treatment times.

Under the current cost containment environment, the competitive factors in the
medical markets served by the Company are such that cost reduction is a prime
consideration. Although cost containment may adversely affect some of the
Company's supply products, cost containment pressures may be a positive factor
for certain of the Company's products such as its dialyzer reprocessing
products, hemoconcentrators, and the Cathetron-Registered Trademark-
Reprocessing System.

                                                                    Page 7 of 53
<PAGE>


Proposals to reform the health care system in the United States are under
consideration at various levels of government.  Areas under review include the
uninsured segment of the population, the rise in national health care
expenditures and the portion of the total gross domestic product (GDP) consumed
by health care costs.  It is possible that changes to the existing health care
system may be enacted into law in the future.  The Company cannot predict the
effect, if any, such changes will have on the Company's operating results.

RESEARCH AND PRODUCT DEVELOPMENT

The Company strives to design and develop technologically advanced products that
are cost effective and, in the case of its medical products, improve the quality
of patient care. The Company emphasizes product development rather than basic
research. The ability of the Company to compete effectively depends upon its
ability to anticipate changing market needs and successfully develop products to
meet those needs.

As of March 31, 1995, 17 of the Company's employees were engaged in research and
development.  In addition to its own research activities, the Company from time
to time obtains experimental and clinical research from outside investigators,
consultants and institutions.

Over the past three years the Company has expended a total of $8,431,000 in
research and development as follows:  fiscal 1993 - $2,405,000, fiscal 1994-
$2,893,000, and fiscal 1995 - $3,133,000. Such costs represented 5.4%, 6.1% and
5.6% of total revenues, respectively, in each such period.

The Company's current research and development efforts are directed toward
reprocessing applications, blood filtration and oxygenation technologies, and

The medical products manufactured and marketed by the Company are subject to the
Federal Food, Drug and Cosmetic Act and the Medical Device Amendments of 1976
(collectively, the "FDCA"). These laws give the Food and Drug Administration
("FDA") extensive regulatory authority over medical products developed,
manufactured or marketed by the Company in the United States. The FDCA requires
the Company to register with the FDA, provide updated device listings and submit
a premarket notification to FDA when (i) a device is being introduced into the
market for the first time; (ii) the manufacturer makes a significant change or
modification to an already marketed device that could affect safety or
effectiveness; or (iii) there is a major change or modification in the intended
use of the device.  The FDCA also requires that the Company submit a premarket
approval application for devices that are life supporting or sustaining, or
present a potential unreasonable risk of injury or illness.  In addition, the
FDCA subjects the Company to the Good Manufacturing Practice regulations under
which the FDA conducts periodic unannounced inspections to verify compliance.
Further, the FDCA imposes certain requirements regarding manufacturing
procedures, distribution, advertising, labeling, and record keeping.  The FDA
also has the power to order suspension of manufacturing or marketing or to
recall products that are not in compliance with law.

Before introducing its products into the market, the Company must comply with
the premarket approval and/or notification provisions of the FDCA.  Data
regarding the product's safety and effectiveness must be submitted to the FDA.
In some instances, clinical studies may be necessary to obtain this data.
Before commencing clinical trials, the Company must apply for an

                                                                    Page 8 of 53

Investigational Device Exemption ("IDE").  Under an approved IDE, a device is
exempt from certain FDA provisions including misbranding, registration, listing,
premarket approval, records and reports and good manufacturing practices, thus
enabling the applicant company to test a device clinically.  Before an IDE is
granted, sufficient nonclinical data must be submitted to demonstrate that the
device is safe and effective.  Significant time and expense may be associated
with the collection of both clinical and nonclinical data and there are no
assurances, that the necessary FDA premarket approvals or clearances will be
granted.

During 1992 and 1993, the time between submission to the FDA and final clearance
for marketing increased substantially; however, review times by the FDA are
beginning to decrease.  Notwithstanding, there are no assurances that this trend
will continue, and the Company is still experiencing delays in receiving product
clearances.

In January 1995, the Company received ISO 9001 certification for its Plymouth,
Minnesota facilities.  This certification allows the Company to self-certify its
products for sale throughout the European Community.  In order to self-certify,
the Company must maintain certain records and files which are reviewed by a
"notified body" organization on an annual basis.  Many of the Company's products
now display the CE (Communaute Europeene) mark.

Certain products of the Company are also subject to registration with the
Environmental Protection Agency (EPA). The registration process generally
entails the collection and submission of data to support the products' label
claims. Considerable time and cost may be involved with the collection of data
to support these submissions, and there are no assurances that the necessary EPA
approvals will be granted for the Company's new products.  Currently, EPA and
FDA have entered into a memorandum of understanding whereby the agencies intend
to cooperate on chemical product submissions that are currently duplicative for
both applicants and the agencies.

Compliance with federal, state, and local provisions regulating the discharge of
materials into the environment, or otherwise relating to the protection of the
environment, do not have a material adverse effect upon the capital
expenditures, earnings, and competitive position of the Company.

EMPLOYEES

As of March 31, 1995,  the Company employed 341 persons, including 244 in
manufacturing operations. None of the employees is covered by a collective
bargaining agreement, and the Company believes its employee relations are good.

GEOGRAPHIC AREA INFORMATION

The major foreign markets for the Company's products are Western Europe and the
Far East. Sales outside the United States for the years ended March 31, 1993,

respectively. Sales outside the United States accounted for approximately 9%,
10% and 13% of total sales in each such period.

ITEM 7.      MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
               CONDITION AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

REVENUES

Total revenues in fiscal year 1995 increased by $8,395,000, or 18%, due to
increased unit sales of all major product lines except for sales of membrane
oxygenators to C.R. Bard, Inc. ("Bard") which remained approximately constant
with the prior year.   Product price increases in fiscal year 1995 accounted for
approximately 10% of the increase in revenue dollars.

Sales of oxygenators to Bard accounted for 25% of revenues in fiscal year 1995
under a contract that was scheduled to expire December 31, 1995.  In April 1995,
a new agreement was reached extending the term to June 30, 1997.  The Company
expects that unit sales of oxygenators to Bard in fiscal year 1996 will
approximate fiscal year 1995 shipments.  Unit sales in fiscal year 1997 are
scheduled to decrease substantially.  The decline in sales to Bard in future
fiscal years is expected to be offset to a certain extent (in whole or in part)
by sales of the Company's second generation oxygenator which was under
development at March 31, 1995.

Total revenues in fiscal year 1994 increased by $3,471,000, or 8%, due primarily
to higher unit sales of dialysis concentrate products and dialyzer reprocessing
supplies which more than offset a decline in unit sales of cardiosurgery
products, primarily membrane oxygenators.  Product price increases in fiscal
year 1994 accounted for approximately 15% of the increase in revenue dollars.

Changes in foreign currency exchange rates did not have a significant impact on
the Company's revenues in fiscal years 1995, 1994 and 1993.

Product sales have grown at a compound annual rate of 17% over the past three
years.  The following table indicates sales and percent of total corporate sales
by product group  for each of the last three fiscal years:

GROSS MARGINS

Gross profit from product sales in fiscal 1995 was $24,108,000, or 43.1% of net
sales, compared to $20,868,000, or 43.9%, in fiscal 1994 and $19,217,000, or
43.7%, in fiscal 1993. The decrease in gross margin in fiscal 1995 resulted
primarily from reduced dialysis concentrate margins. The improvement in gross
margin in fiscal 1994 resulted from higher manufacturing volumes of dialysis
concentrate and manufacturing efficiencies which lowered unit costs.  Unabsorbed
dialyzer manufacturing costs depressed gross margins in each of fiscal years
1995, 1994, and 1993.

Some of the Company's research and development efforts are directed to the
development of new versions of existing products.  Gross margin in the past has
not been materially impacted by obsolete inventories resulting from the
introduction of new products. The Company does not expect inventory obsolescence
to impact gross margins significantly in the foreseeable future.

RESEARCH AND DEVELOPMENT

Research and development expenses increased in each of the past three fiscal
years. Development expenditures in fiscal 1995 were $3,133,000, or 5.6% of total
revenues, compared to $2,893,00, or 6.1% of total revenues, in fiscal 1994 and
$2,405,000, or 5.4% of total revenues, in fiscal 1993.  The higher expenses in
fiscal years 1995 and 1994 reflected planned increases in development
activities.  The Company intends to continue investing a substantial portion of
its revenues in new product development.  The Company expects that total
research and development expenses in fiscal 1996 will approximate 6% of
revenues.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general, and administrative expenses as a percentage of total revenues
were 21.3% in fiscal 1995 compared to 21.0% in fiscal 1994 and 21.6% in fiscal
1993. The higher costs in fiscal 1995 were due primarily to increases in sales
staffs and expanded marketing efforts in the United States and Europe.  Fiscal
1994 expenses included $566,000 of legal expenses associated with a lawsuit in
which the Company was the plaintiff.  The lawsuit was settled in April 1994. The
Company expects selling, general, and administrative expenses will approximate
22% of total revenues in fiscal 1996.

INCOME TAXES

The Company recorded an income tax provision in fiscal 1995 of $3,294,000, an
effective tax rate of 35.8%, compared to effective tax rates of 38.1% in fiscal
1994 and 37.4% in fiscal 1993. The decrease in the Company's income tax rate in
fiscal 1995 was due primarily to the deduction of losses related to the
investment in a foreign subsidiary.  The Company expects that its income tax
rate in fiscal 1996 will be approximately 36%.

NET EARNINGS

Net earnings increased by 20% in fiscal 1995 and totaled $5,920,000, or 10.5% of
total revenues, compared to net earnings of $4,935,000, or 10.3% of total
revenues, in fiscal 1994 and net earnings of $4,719,000, or 10.6% of total
revenues, in fiscal 1993. The increase in earnings in fiscal years 1995 and 1994
was due to higher sales revenues.

INFLATION

Management believes inflation has not had a material effect on the Company's
results of operations or on its financial condition.

LIQUIDITY AND CAPITAL RESOURCES

The Company continues to maintain a strong balance sheet, as evidenced by the
following liquidity trends:

</TABLE>

The decrease in cash and cash equivalents in fiscal 1995 was due primarily to
real estate acquisitions, retirement of long-term debt, and the acquisition of a
product line.  The Company's current ratio at March 31, 1995 was 4.6 to 1
compared to 5.4 to 1 at March 31, 1994.  The Company has an unused $2,000,000
bank line of credit that allows the Company to borrow on an unsecured basis at
the prime rate of interest (9% at March 31, 1995).

Inventories and accounts receivable increased during fiscal 1995 due primarily
to the increased level of sales.

During fiscal 1995, the Company retired mortgage debt of $1,942,000 on one of
its buildings, purchased a 21,000 square foot building in Heerlen, The
Netherlands for $1,539,000, and acquired 5.2 acres of undeveloped land in
Plymouth, Minnesota for $530,000.  The Company also continued to expand its
production facilities to increase capacity to manufacture new products in fiscal
1995.  The Company expended a total of $3,573,000 for plant improvements and
equipment in fiscal 1995 compared to $2,970,000 in fiscal 1994 and $3,270,000 in
fiscal 1993.  The Company plans to invest approximately $4,000,000 in capital
equipment in fiscal 1996 to meet the needs of its expanding business.

In fiscal 1995, the Company acquired an endoscope reprocessing product line for
$934,000, paid in cash. Subsequent to year-end, in April 1995, the Company
acquired a group of hollow fiber product lines for $1,402,000 in cash, payable
in two cash installments through July 1995. Assets acquired in both of these
transactions included inventory, equipment, and goodwill.

During fiscal years 1994 and 1993, the Company repurchased 27,500 shares and
98,200 shares of its common stock in open market transactions for $264,000 and
$1,337,000, respectively.

The Company believes that its strong financial condition at March 31, 1995,
along with funds expected to be generated from operations, will be sufficient to
meet its working capital and capital equipment needs in fiscal 1996.

FOREIGN CURRENCY TRANSACTIONS

Substantially all of the Company's U.S.-based export sales are invoiced and paid
in U.S. dollars.  The transactions of the Company's German-based subsidiary are
invoiced and paid in German marks and U.S. dollars.  The Company does not
currently hedge its foreign currency transactions. Accordingly, the Company is
subject to risks associated with fluctuations in currency exchange rates.

</TABLE>

A substantial portion of the Company's cash balances are held in one financial
institution.

Commercial paper and municipal bonds are stated at fair value, which
approximates cost at March 31, 1995 and 1994.

MARKETABLE SECURITIES

The Company adopted the provisions of Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities" (SFAS 115), on April 1, 1994.  In accordance with SFAS 115, prior
period financial statements were not restated to reflect the change in
accounting principle.  The effect of applying the new standard to prior periods
would not have had a material impact on the Company's financial statements.

Marketable securities consisted of investments in bond funds.  At March 31,
1995, the adjusted cost and fair value were $1,402,410 and $1,162,607,
respectively.  Unrealized holding losses amounted to $239,803.  These holding
losses, net of income taxes, are reported as a reduction in stockholders'
equity.

</TABLE>

PROPERTY AND EQUIPMENT

Property and equipment are depreciated on a straight-line basis over their
estimated service lives.  Accelerated and straight-line methods are used for
income tax reporting purposes.

PATENT COSTS
Patent application costs consist principally of legal and filing fees and are
capitalized and amortized over five years.

GOODWILL

Goodwill represents the cost in excess of the fair value of net assets acquired
and is amortized using the straight-line method over five to seven years.  The
Company periodically evaluates the existence of goodwill impairment on the basis
of whether the goodwill is fully recoverable from projected, undiscounted net
cash flows of the related business unit.

RESEARCH AND DEVELOPMENT

Research and development costs are charged to operations as incurred.

INCOME TAXES

Effective April 1, 1993, the Company adopted Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes."  This standard required a
change from the deferred method of accounting for income taxes.  Under the asset
and liability method of Statement 109, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to differences between
the financial statement carrying amounts of existing assets and liabilities and
their respective tax bases. The adoption of this standard did not have a
material impact on the Company's financial statements and no cumulative effect
adjustment was required.

FOREIGN CURRENCY TRANSLATION

Foreign assets and liabilities are translated to U.S. dollars at year-end
exchange rates.  Revenues and expenses are translated at the average exchange
rates in effect for the year.  Unrealized translation adjustments are reported
as a component of stockholders' equity.

RECLASSIFICATIONS

Certain reclassifications have been made to conform the 1993 and 1994 financial
statements to the 1995 presentation.

                              MINNTECH CORPORATION

                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN



THIS INSTRUMENT establishes the Minntech Corporation Supplemental Executive
Retirement Plan effective as of April 1, 1995.


     SEC. 1.  PURPOSE OF PLAN.  The purpose of this Plan is to permit a select
group of management employees and directors to defer a portion of their
compensation to a later date and to provide these employees and directors with
supplemental retirement benefits as set forth herein.

     SEC. 2.  DEFINITIONS.  When used in this Plan, the following terms shall
have the meanings assigned below:

     2.1  BOARD.  "Board" is the Board of Directors of Minntech Corporation.

     2.2  COVERED COMPENSATION.  "Covered Compensation" is the base salary
earned by the Participant for the Plan Year.  For a Board member, "Covered
Compensation" is directors' fees.

     2.3  DEFERRED COMPENSATION.  "Deferred Compensation" is the portion of a
Participant's Covered Compensation and Incentive Compensation which the
Participant has elected to defer under Section 3 of this Plan.

     2.4  INCENTIVE COMPENSATION.  "Incentive Compensation" is the Participant's
annual cash bonus accrued by the Employer on the last day of the Plan Year and
payable thereafter to the Participant.

     2.5    MINNTECH.  "Minntech" is Minntech Corporation, a Minnesota
corporation.  Minntech Corporation is the administrator of the Plan.  The chief
financial officer of Minntech is authorized to perform general administrative
functions under the Plan on behalf of Minntech.

     2.6    PARTICIPANT.  A "Participant" is any executive or management level
employee of Minntech who meets all of the following three requirements:  (i) the
individual is an officer, (ii) the individual is a highly compensated employee
as defined in Internal Revenue Code Section 414(q), and (iii) the individual is
a member of a select group of management or highly compensated employees within
the meaning of Sections 201(2), 301(a)(3) and 401(a)(1) of the Employee
Retirement Income Security Act of 1974.  "Participant" also means any Board
member.  Each such employee or Board member shall continue to be eligible to
contribute to this Plan until such individual ceases to be an employee or Board
member as described above; provided, however, that the individual shall continue
to be a Participant in this Plan until his or her benefits are fully paid.  The
Board, from time to time, may provide by resolution for additional positions
that will qualify for participation in this Plan, provided, however, that any
such employee must satisfy clauses (ii) and (iii) of the first sentence of this
section.

     2.7  PLAN YEAR.  The "Plan Year" is the 12 month period ending on each
March 31.

                                                            Page 35 of 53

     SEC. 3.   DEFERRED COMPENSATION.

     3.1  DEFERRAL ELECTION.  Each Participant may elect to have treated as
Deferred Compensation amounts which are earned or ascertained subsequent to the
date of such election, subject to the following:

     (a)   The maximum amounts that may be elected for any Plan Year are:

          (1)  10% of the Participant's Covered Compensation in the case of an
               employee, and 100% of the Participant's Covered Compensation in
               the case of a Board member.

          (2)  90% of the Participant's Incentive Compensation.

     (b)  An election of Deferred Compensation pursuant to this Section shall be
          in writing, and  shall be made on or before the March 30 prior to the
          beginning of the Plan Year.  The Election shall apply to Covered
          Compensation and Incentive Compensation payable during the next Plan
          Year.  Such election shall remain in effect for and shall be
          irrevocable during the Plan Year, except that a Participant who is
          determined by the Company in its sole discretion to have incurred a
          financial hardship as defined in Section 6 may elect to completely
          discontinue future deferrals.  A new election may be made for each
          subsequent Plan Year.  If no election is made by a Participant prior
          to the first day of any Plan Year, the election in effect for the
          prior Plan Year, if any, shall continue in effect.

     (c)  Notwithstanding subsection (b), within 30 days of the date on which
          the Participant first becomes eligible to participate in the Plan, the
          Participant may make an election of Deferred Compensation for Covered
          Compensation with respect to services to be performed subsequent to
          the election.

     (d)  Notwithstanding the foregoing, no amounts shall be deferred from any
          Covered or Incentive Compensation that is payable on a date that is
          after the individual's termination of employment or directorship
          occurred.

     3.2  PARTICIPANT ACCOUNT.  On the date that an amount of Deferred
Compensation under Section 3.1 would otherwise be paid to the Participant, the
amount of such Deferred Compensation shall be credited to an account on the
books of Minntech.  No Participant shall derive any rights or benefits in or to
any assets of Minntech solely from the establishment or maintenance of such
accounts on the books of Minntech.

     SEC. 4. DEEMED INVESTMENT OF DEFERRALS.

     4.1  ELECTION OF DEEMED INVESTMENT.  Each Participant shall designate the
form and percentage of deemed investment options in Section 4.2 at the time of
his or her annual election of Deferred Compensation on a form provided by
Minntech.  The Participant may change the form or percentage of deemed
investment options during his or her period of employment or directorship with
Minntech by filing a new form with Minntech.  The new investment options shall
apply to the period on and after the first day of the calendar quarter following
the date on which the change is filed with Minntech and before the effective
date of a subsequent election.  Any election that is effective on a date other
than April 1st must be filed at least 10 days prior to the effective date.  All


                                                            Page 36 of 53




<PAGE>


elections must be expressed in 25% increments for each investment option.  The
Participant may file separate elections for the deemed investment of the
existing account balance and the deemed investment of future deferrals.

     4.2  INVESTMENT OPTIONS.  Prior to the time any Deferred Compensation is
actually paid to the Participant as provided below, the Deferred Compensation
amount shall be increased by the gain or decreased by the loss (the
"adjustment") determined on the basis of the following forms of investments as
selected by the Participant as in effect from time to time during the period
after the Deferred Compensation amount was credited to the Participant's
account.

(a)  Fidelity Magellan Fund.

(b)  Fidelity Growth and Income Fund.

(c)  Fidelity Intermediate Bond Fund.

(d)  Fidelity Overseas Fund.

(e)  Fidelity Spartan Money Market Fund.

(f)  Kaufmann Fund.

(g)  Such other investments that Minntech may from time to time add to the Plan.

If an investment option becomes unavailable, Minntech may replace the option
with one that maintains similar investment characteristics.  Minntech may in its
sole discretion add additional options or delete options at any time.

     4.3  ACCOUNT INFORMATION.  The selection of investments by which
adjustments to the Participant's Deferred Compensation will be determined shall
be solely for the purpose of establishing a method of calculating the
adjustments in such Deferred Compensation and shall not obligate Minntech to set
aside any assets or to invest any assets it may set aside in such investment or
in any particular type of investment.  Adjustments shall be determined in each
fund by Minntech no less often than annually, and Minntech's determination shall
be final.  Minntech shall provide each Participant with a report of the account
value as of the end of each Plan Year, or more frequently.

     SEC. 5.  DISTRIBUTIONS FROM ACCOUNTS.

     5.1  TERMINATION WITH MINNTECH.  Following termination of employment or
directorship with Minntech, the Participant shall receive cash distribution of
the Deferred Compensation account at the time and in the manner specified by the
Participant under Section 5.2.

     5.2  TIMING AND FORM OF DISTRIBUTION.  At the time of initial enrollment in
the Plan, Participants shall elect to have their accounts distributed to them
(or their beneficiaries) at the times and in the manner provided below.  Such
elections shall be made in writing and are irrevocable.

     (a)  Participants may elect to have distributions commence at the following
          times:

          (1)  In the calendar year of the Participant's termination of
               employment or directorship with Minntech.

          (2)  In the calendar year following the Participant's termination of
               employment or directorship with Minntech.


                                                            Page 37 of 53



<PAGE>


          (3)  Following the fifth anniversary of the Participant's termination
               of employment or directorship with Minntech.

          (4)  In the calendar year in which there occurs the later of (i) the
               Participant's 60th birthday, or (ii) the Participant's
               termination of employment or directorship with Minntech.

     (b)  Participants shall elect to have their accounts distributed in one of
the following forms, subject to approval by Minntech:

          (1)  A single lump sum.

          (2)  Distribution in substantially equal quarterly installments
               ranging from two to 10 years.

          Lump sum distributions shall be paid on the 15th day of the first
          calendar quarter immediately following the date the applicable event
          specified in subsection (a) occurs.  Installment payments shall also
          commence on the same date, with succeeding amounts paid on the 15th
          day of each calendar quarter thereafter until paid in full.  The
          amount of each installment shall be determined by dividing the total
          of the account by the number of installments remaining to be paid,
          including the current installment. During the installment period,
          earnings or losses on all unpaid amounts shall be credited in
          accordance with the Participant's deemed investment election at the
          commencement of payments.

     (c)  Notwithstanding the foregoing, if a Participant had less than five
years of employment or directorship with Minntech at the time the termination of
employment or directorship occurs, the entire benefit under the Plan shall be
paid in a lump sum on the earlier of (i) the date payments are to commence under
subsections (a) and (b), or (ii) January 15th of the year following the calendar
year in which the termination of employment or directorship occurred.

     5.3  DISTRIBUTION TO BENEFICIARY.  If the Participant is deceased, the
distribution shall be payable to the beneficiary of the Participant in the form
payable to the Participant hereunder.  Minntech, in its sole discretion, may
accelerate the payment of benefits under this Plan to the Participant's
beneficiary.

     SEC. 6.  DISTRIBUTIONS FOR FINANCIAL HARDSHIP.  Participants may withdraw
any portion of their Deferred Compensation account without regard to the
provisions of Section 5, in the event the Participant, in the sole discretion of
Minntech, has incurred, or will incur, an immediate and heavy financial
hardship.

     (a)  A distribution based upon financial hardship shall not exceed the
          amount required to meet the immediate financial need created by the
          hardship and not reasonably available from other resources of the
          Participant.  A "financial hardship" for purposes of this section must
          involve an unforeseeable emergency that is caused by events beyond the
          control of the Participant.

     (b)  An application for a distribution pursuant to this section shall be
          made in writing and delivered to the chief financial officer of
          Minntech.  Minntech may require the submission of such supporting
          documentation as it deems necessary and shall render its final and
          conclusive decision on such applications.

     SEC. 7.  FUNDING.  Nothing in this Plan shall be construed as permitting a
Participant or beneficiary to claim any security for the fulfilling of the
obligations of Minntech hereunder, and the Participant or beneficiary shall look
only to the general assets of Minntech for the satisfaction of Minntech's
obligations.  Minntech is not required to invest in any property to secure its
obligations under this Plan.  If Minntech should invest in property to fund its
obligations under this Plan, Minntech shall be the sole owner of such property,
and the Participant, beneficiary and estate shall have no rights in said
property.  If Minntech obtains an insurance contract in connection with its
obligations under this Plan, the Participant shall cooperate with Minntech and
shall execute any documents reasonably requested by Minntech to obtain such
insurance.

     SEC. 8.  DESIGNATION OF BENEFICIARY.  Each Participant shall file with
Minntech a written designation of the person or persons to receive the benefits
under this Plan in the event of the Participant's death.  This right of the
Participant shall include the right to name and change primary and contingent
beneficiaries.  Any designation of beneficiaries shall be effective only when
filed by the Participant in writing with Minntech during the Participant's
lifetime.  In the absence of such written designation, or if all the
beneficiaries so named predecease the Participant, the individuals in the first
of the following classes in which there is a survivor, share and share alike,
shall be considered the designated beneficiary:

     (a)  The Participant's spouse, if surviving, with unpaid amounts at the
          spouse's death payable to the spouse's estate or as otherwise
          designated by the spouse.

     (b)  The Participant's surviving children and surviving issue of deceased
          children, such issue of deceased children taking by right of
          representation.

     (c)  The Participant's estate.

     SEC. 9.  CLAIMS PROCEDURE.

     9.1  CLAIMS PROCEDURE AND REVIEW.  A Participant or beneficiary may make a
claim for Plan benefits within the time and in the manner described herein.
Such claim shall be made within 60 days after the claim arises by filing a
written request with the chief financial officer of Minntech.  The claim shall
be determined by Minntech within 90 days after the receipt of the written claim.
Notice of Minntech's decision shall be communicated to the claimant in writing.
If the claim is denied, the notice shall include the specific reasons for the
denial (including reference to pertinent Plan provisions), a description of any
additional material or information necessary for Minntech to reconsider the
claim, the reasons for any of such additional material or information, and an
explanation of the review procedure.

     9.2  APPEAL.  The claimant or a duly authorized representative may, within
60 days after receiving such written notice, request the president of Minntech
to review Minntech's decision.  The president shall afford the claimant a
hearing and the opportunity to review all pertinent documents and submit issues
and comments orally or in writing and shall render a review decision in writing
within 60 days after receipt of request for review.  The review proceeding shall
be conducted in accordance with the rules and regulations adopted from time to
time by the president of Minntech.

     9.3  ATTORNEYS' FEES AND COSTS OF LITIGATION.  If a Participant or
beneficiary who has exhausted the above claims procedure subsequently brings an
action in court and receives a final judgment that he or she is entitled to a
greater benefit than Minntech had determined, Minntech shall reimburse the
individual for all reasonable attorneys' fees and related costs incurred in
obtaining and enforcing the judgment.

     SEC. 10.  MISCELLANEOUS.

     10.1 LIABILITY.  No officer of Minntech shall be personally liable by
virtue of any contract, agreement or other instrument made or executed by the
officer or on his or her behalf as an officer, nor for any mistake or judgment
made by such officer or any other officer, nor for any negligence, omission or
wrongdoing of any other officer or of anyone employed by Minntech, nor for any
loss, unless resulting from his or her own gross negligence or willful
misconduct.  In addition, Minntech does not assure or guarantee the tax
consequences of benefits provided hereunder or other matters beyond its control.

     10.2 TITLE TO ASSETS.  No Participant or former Participant shall have any
legal or equitable right or interest in any funds set aside by Minntech or in
any assets in which Minntech may invest, from time to time, to cover its
obligations under this Plan.

     10.3 AMENDMENTS.  Minntech reserves the right to amend or modify, in whole
or in part, any or all of the provisions of this Plan at any time by action of
the Board or by a written instrument executed by the president of Minntech;
provided, however, that no amendment or modification shall be made which will
deprive any Participant or any Participant's beneficiary of any vested benefits
to which he or she is entitled under the Plan.  Notwithstanding the foregoing,
the amendment can alter the deemed investment options under Section 4 with
respect to periods after the date the amendment is adopted, both for future
deferrals and for amounts deferred in past.

     10.4 TERMINATION.  Continuation of the Plan is not a contractual obligation
of Minntech, and the right is reserved by Minntech to reduce, suspend or
discontinue the Plan at any time by action of the Board or by written instrument
executed by the president of Minntech.  However, no such reduction, suspension
or discontinuance shall deprive any Participant or beneficiary of any benefits
that become vested under the Plan prior to the termination, but may alter future
deemed investments as provided in Section 10.3.

     10.5 ASSIGNMENT AND LEVY.  The Plan is for the benefit and protection of
the Participants and their beneficiaries and the rights, privileges and benefits
herein conferred shall not, to the extent permitted by law, be subject to
alienation, assignment, pledge, levy, attachment, garnishment or other legal
process or in any manner anticipated, encumbered, committed, withdrawn or
surrendered, and neither shall the same be subject or liable in any way for
debts, contracts, or agreements or other claims of creditors of such
Participants or their beneficiaries whether such claims are now contracted or
may hereafter be contracted or incurred.

     10.6 PARTICIPANT'S RIGHTS.  The establishment of this Plan shall not create
any legal or equitable right against Minntech unless such right is specifically
provided for in this Plan. Furthermore, nothing in this Plan shall be construed
as giving a Participant the right to be retained in the employment of Minntech,
and a Participant shall remain subject to discharge at any time to the same
extent as if this Plan had not been adopted.

     10.7 INCOMPETENCY.  Every person receiving or claiming benefits under this
Plan shall be conclusively presumed to be mentally competent until the date on
which Minntech receives a written notice in a form and manner acceptable to
Minntech that such person is incompetent and that a guardian, conservator or
other person legally vested with the care of his or her estate has been
appointed.  In such event, Minntech may direct payments of benefits to such
guardian conservator or other person legally vested with the care of the
person's estate and any such payments so made shall be a complete discharge of
Minntech to the extent so made.

     10.8 NOTICES.  Notices required by this Plan to be given to Minntech or a
Participant shall be in writing and shall be considered to have been duly given
or served if personally delivered, or sent by first class, certified or
registered mail.

     10.9  SEVERABILITY.  The invalidity or partial invalidity of any portion of
this Plan shall not invalidate the remainder thereof, and said remainder shall
remain in full force and effect.

     10.10  RELEASE.  Any payment to or for the benefit of any Participant or
beneficiary in accordance with the provisions hereof shall, to the extent
thereof, be in full satisfaction of all claims hereunder against Minntech.

     10.11  WITHHOLDING OF TAXES.  The benefits payable under this Plan shall be
subject to the deduction of any federal, state or local income taxes or other
taxes which are required to be withheld from such payments by applicable laws
and regulations.

     10.12  GOVERNING LAW.  Construction and administration of this Plan shall
be governed by the laws of the State of Minnesota, except to the extent such
laws are preempted by federal law.

     [Minntech Letterhead]






                                             March 22, 1995



Mr. Robert M. Rosner                              BY HAND
1571 17th Avenue N.W.
New Brighton, MN  55112


Dear Bob:


          1.   You have decided to voluntarily terminate your employment with
Minntech Corporation ("Minntech") effective May 31, 1995.  Because of the many
years of service you have given to Minntech and the anticipated continued
relationship between you and Minntech as described below, this letter describes
Minntech's offer of severance in connection with your voluntary termination.
After reading this letter, if you agree to the terms set forth herein, please
return a signed copy to me as described below.

          2.   Although not obligated to do so, in exchange for agreeing to the
terms set forth in this letter, we have offered to provide you with the
following severance benefits.  Minntech will pay to you a guaranteed amount
equal to six (6) months' salary (payable semi-monthly in the amount of
$3,857.12) commencing June 1, 1995 and ending November 30, 1995 (the "Post-
Termination Period") whether you commence employment elsewhere or remain
unemployed.  If Minntech for any reason whatsoever asks you to leave prior to
May 31, 1995, it will continue to pay you an amount equal to $3,857.12 semi-
monthly through May 31, 1995 and thereafter as provided herein.

          3.   In the event you become deceased at any time by reasons other
than suicide (i) from the signing of this Severance Agreement to May 31, 1995,
(ii) during the Post-Termination Period, or (iii) during the Additional Period,
Minntech will continue to pay your designated beneficiary a semi-monthly payment
of $3,857.12 until May 31, 1996.

          4.   You agree to make a good faith effort to find employment.

                                            Page 42 of 53




<PAGE>


          5.   If you do not find employment during the Post-Termination Period
and sign a second release of claims (in the form attached hereto) on or after
May 31, 1995, Minntech will continue to pay you semi-monthly in the amount of
$3,857.12 for each month you remain unemployed for up to six additional (6)
months commencing December 1, 1995 and ending May 31, 1996 (the "Additional
Period").  If you commence such employment during the Post-Termination or
Additional Period, you agree to notify Minntech and Minntech's obligation to
make the aforementioned salary payment during the Additional Period shall cease.
The term "employment" as used in this paragraph shall mean any employment
whether de minimis or not.

          6.   You will also be eligible under the Minntech Management Incentive
Compensation Plan for a performance bonus for work performed during fiscal year
ending March 31, 1995, which is payable on or about June, 1995.  As you know
however, the determination of the amount of bonus paid to any employee is at the
discretion of the President and may vary from employee to employee. Because that
determination has not yet been made, Minntech cannot guarantee a fixed amount to
you at this point in time.

          7.   In exchange for the foregoing payments, you agree (a) to serve as
a consultant to Minntech during (i) the Post-Termination Period and (ii) the
Additional Period for so long as the aforementioned semi-monthly payments are
being made to you; (b) to remain an employee of Minntech through May 31, 1995 in
order to  assist as necessary on the audit for fiscal year-ended March 31, 1995,
transfer files and projects, and accomplish an orderly transition; (c) agree to
the release of claims as explained more fully below; and (d) to execute the new
form of employee agreement dated April 1, 1995 (the "Employment Agreement").  In
regard to (a) above, the consulting agreement shall be in accordance with the
agreement attached hereto (the "Consulting Agreement").  In the event that
either party terminates the Consulting Agreement as provided therein, except as
otherwise set forth in paragraph 11, release of the claims set forth in this
Severance Agreement shall remain in effect and shall be fully enforceable by
each party.  In regard to (d) above, the Employment Agreement shall be in
accordance with the agreement attached hereto; provided, however, that this
Severance Agreement shall supersede both parties' right to terminate at will
under the Employment Agreement.

          8.   You will remain on the group insurance plan through May 31, 1995.
Thereafter, you will be eligible for an extension of those insurance benefits
for eighteen (18) months under COBRA.

          9.   For the reasons set forth below, the payments to you would
commence on the later of June 15, 1995 or seventeen (17) days after you sign
this Agreement and return it to me, if you do not rescind your release of
claims.

          10.  As you have offered, you will continue to serve as a Board member
(with no per meeting payment) until the Annual Meeting of Shareholders in
August, 1995.

                                            Page 43 of 53




<PAGE>


          11.  As consideration for the severance package set forth above,
except for claims related to non-performance by Minntech under this Severance
Agreement and the Consulting Agreement, you agree to release Minntech, its
officers, directors, agents and employees from any and all claims and causes of
action which you may have against them.  As consideration for your release of
claims, except for claims related to breach of your obligations related to non-
competition and disclosure of confidential information under the Employment
Agreement and non-performance under the Consulting Agreement, Minntech releases
you from any and all claims and causes of action which it may have against you.

          12.  Through these releases, both parties extinguish any and all
causes of action against the other occurring up to the date of this Agreement,
including, but not limited to, impairment of economic opportunity or any
contract claims, intentional inflection of emotional distress or any other tort,
and all claims arising from any federal, state or municipal law or ordinance.
Your release also extinguishes any potential claims of employment discrimination
arising from your employment and termination of employment with Minntech,
including specifically any claims under the Minnesota Human Rights Act, the
Federal Age Discrimination in Employment Act, or Title VII of the Civil Rights
Act of 1964.  You are advised to consult an attorney prior to signing your
acknowledgment to this Agreement.

          13.  Because this Severance Agreement includes a release of any rights
you may have under the Age Discrimination in Employment Act, under federal law
you are entitled to a period of at least twenty-one (21) days from your receipt
of this letter during which to consider that agreement.  You have the full
twenty-one (21) days during which to consider the terms of this Agreement, and
we encourage you to use the waiting period to consider this proposal if you so
desire.  If, with full knowledge of your right to the twenty-one (21) day
waiting period, you wish to waive all or any part of that twenty-one (21) day
waiting period, you may do so by signing the acknowledgment attached to the
severance agreement that confirms your choice to waive the twenty-one (21) day
waiting period.

          14.  Under Minnesota Statutes, you have the right to rescind your
release of only those rights and remedies secured by the Minnesota Human Rights
Act, Minnesota Statute Chapter 363, within fifteen (15) calendar days of your
execution of this release.  To be effective,  your rescission must be in writing
and delivered to Minntech Corporation, Attention:  Louis C. Cosentino, Ph.D.,
President, 14605 28th Avenue North, Minneapolis, Minnesota 55447, either by hand
or mail, within the fifteen (15) day period.  If delivery is my mail, the
rescission must be (i) postmarked within the fifteen (15) day period; (ii)
properly addressed to Minntech at the address stated in the preceding sentence;
and (iii) sent by certified mail, return receipt requested.  If you effectively
exercise this right of rescission, this Agreement shall be rendered null and
void, with neither you nor Minntech having any further obligation to the other
under this Agreement, except that your resignation will remain in effect and you
shall

                                            Page 44 of 53




<PAGE>


then promptly reimburse Minntech for any payments or other benefits received by
you under this Agreement.

          15.  Upon your execution of this Agreement, we will arrange to speak
with you seventeen (17) days after the date you sign this Agreement (or the next
business day after that date if the seventeenth day falls on a weekend).  If you
have not exercised your right to rescind this Agreement and confirm that fact to
us, Minntech will then commence your continued salary payment as set forth
above, if it is on or after June 15, 1995.

          16.  This Severance Agreement and General Release shall not in any way
be construed as an admission of liability by Minntech Corporation or as an
admission that Minntech has acted wrongly with respect to you.  Minntech
Corporation specifically denies and disclaims any such liability or wrongful
acts.

          17.  This Severance Agreement and the attached Consulting and
Employment Agreements set forth the entire agreement between you and Minntech
and fully supersede any prior agreements or understandings between you and
Minntech, concerning your termination of employment.  This Agreement does not
amend or in any manner limit any of your post-employment obligations to
Minntech, including your obligations regarding non-competition and non-
disclosure of confidential information under the Employment Agreement, as more
fully set forth in the attached letter.  We ask that our records reflect that
you conclude your employment with Minntech on terms you understand and accept.
Therefore, we ask you to declare that you have entered into these Agreements
voluntarily, without coercion or duress, and with the opportunity to review its
contents with legal counsel if you so desire.  We ask you to reflect on the fact
that this Severance Agreement releases all known and unknown claims against
Minntech Corporation.

          18.  If you accept Minntech's severance package as outlined herein,
please sign the original and two copies and return the original and one copy to
me.  The second copy is for your files.  Additionally, if you decide to accept
this Severance Agreement prior to the end of the twenty-one (21) day waiting
period, also sign the attached acknowledgement that you are voluntarily waiving
the waiting period.


          Thank you for your twenty years of service to Minntech.  I know that I
speak for everyone at Minntech in wishing you both personal satisfaction and
continued professional success as you enter this new phase of your life.

               Very truly yours,

                       /s/


               Louis C. Cosentino, Ph.D.
               President

                              CONSULTING AGREEMENT



     CONSULTING AGREEMENT, Made and entered into as of the

a Minnesota corporation (the "Company"), and Robert M. Rosner, an
individual and resident of New Brighton, Minnesota ("Consultant").

     WHEREAS, in consideration for entering into the Severance Agreement dated

     3.  CONSIDERATION.  (a)  In consideration for Consultant's services and

monthly payments made to Consultant.

     4.  IMPROVEMENTS AND INVENTIONS.

     a.  NOTIFICATION AND DISCLOSURE.  Consultant shall promptly notify the
Company in writing of the existence and nature of, and shall promptly and fully
disclose to the Company, any and all ideas, designs, practices, processes,
apparatus, improvements and inventions, whether or not they are believed to be
patentable (all of which are hereinafter sometimes referred to as "inventions"),
which Consultant has conceived or first actually reduced to practice and/or may
conceive or first actually reduce to practice during the period of Consultant's
consulting arrangement with the Company or which Consultant may conceive or
reduce to practice within six (6) months after termination of this Agreement, if
such inventions relate to a product or process upon which Consultant worked
during the term of his consulting arrangement with the Company.

     b.  OWNERSHIP AND PATENTING OF INVENTIONS.  All such inventions shall be
the sole and exclusive property of the Company or its nominee, and during the
term of this Agreement and thereafter, whenever requested to do so by the
Company, Consultant shall execute and assign any and all applications,
assignments and other instruments that the Company shall deem necessary or
convenient in order to apply for and obtain Letters Patent of the United States
and/or of any foreign countries for such inventions and in order to assign and
convey to the Company or its nominee the sole and exclusive right, title and
interest in and to such inventions.  Consultant will render aid and assistance
to the Company in any interference or litigation pertaining to such inventions,
and all expenses reasonably incurred by Consultant at the request of the Company
shall be borne by the Company.

     c.  LIMITATION.  The provisions of this Section 4 shall not apply to any
invention meeting the following conditions:

     (1)  such invention was developed entirely on Consultant's own time;

     (2)  such invention was made without the use of any of the equipment,
     supplies, facility or trade secret information of the Company;


                                            Page 48 of 53



<PAGE>


     (3)  such invention does not relate (i) directly to the business of the
     Company, of (ii) to the Company's actual or demonstrably anticipated
     research or development;

     (4)  such invention does not result from any work performed by Consultant
     for the Company; and

     (5)  encompasses Consultant's general knowledge.

     5.  Protection of Trade Secrets, Know-How and/or Other Confidential
Information of the Company.

     a.  Confidential Information.  Except as permitted or directed by the
Company's Board of Directors, during the term of this Agreement or at any time
thereafter Consultant shall not divulge, furnish or make accessible to anyone or
use in any way (other than in the ordinary course of the business of the
Company) any confidential or secret knowledge or information of the Company
which Consultant has acquired or become acquainted with or will acquire or
become acquainted with prior to the termination of the period of his employment
by the Company (including employment by the Company or any affiliated companies
prior to the date of this Agreement), whether developed by himself or by others,
concerning any trade secrets, confidential or secret designs, processes,
formulae, plans, devices or material (whether or not patented or patentable)
directly or indirectly useful in any aspect of the business of the Company, any
customer or supplier lists of the Company, any confidential or secret
development or research work of the Company, or any other confidential
information or secret aspects of the business of the Company.  Consultant
acknowledges that the above-described knowledge or information constitutes a
unique and valuable asset of the Company acquired at great time and expense by
the Company and its predecessors, and that any disclosure or other use of such
knowledge or information other than for the sole benefit of the Company would be
wrongful and would cause irreparable harm to the Company.  Both during and after
the term of this Agreement, Consultant will refrain from any acts or omissions
that would reduce the value of such knowledge or information to the Company.
The foregoing obligations of confidentiality, however, shall not apply to any
knowledge or information which is now published or which subsequently becomes
generally publicly known in the form in which it was obtained from the Company,
other than as a direct or indirect result of the breach of this Agreement by
Consultant.

     b.  KNOW-HOW AND TRADE SECRETS.  All know-how and trade secret information
conceived or originated by Consultant which arises out of the performance of his
obligations or responsibilities under this Agreement or any related material or
information shall be the property of the Company, and all rights therein are by
this Agreement assigned to the Company.

     6.  TERMINATION.  Notwithstanding any contrary provision contained
elsewhere in this Agreement, this Agreement and the rights and obligations of
the Company and Consultant hereunder (other than the rights and obligations of
the parties under Section 4 or 5 or under the Severance Agreement) shall be
terminated upon the occurrence of any of the following events:

     a.   Immediately in the event of Consultant's death, provided, however,
that the payments made to Consultant in accordance with the Severance Agreement
shall continue until May 31, 1996 so long as such death was not caused by
suicide; or

     b.   Upon thirty (30) days' prior written notice to Consultant if
Consultant has failed in any material respect to perform his consulting
responsibilities hereunder and such default is not cured within the sixty (60)
day period following such notice.  Any such notice given to Consultant pursuant
to this Section 6(b) shall specify the default.

     In the event this Agreement is terminated pursuant to Section 6(b) prior to
the expiration of the term hereof, Consultant shall be entitled to receive
payments made in accordance with the Severance Agreement through the date of
termination, but all other rights to receive such payments shall terminate on
such date.

     7.  MISCELLANEOUS.

     a.  ASSIGNMENT.  This Agreement and the rights and obligations of the
parties hereunder shall not be assignable, in whole or in part, by either party
without the prior written consent of the other party.

     b.  GOVERNING LAW.  This Agreement shall be construed and enforced in
accordance with the laws of the state of Minnesota.

     c.  ENTIRE AGREEMENT.  This Agreement and the Severance Agreement evidences
the entire understanding and Agreement of the parties hereto relative to the
consulting arrangement between Consultant and the Company and the other matters
discussed herein.  This Agreement and the Severance Agreement supersede any and
all other agreements and understandings, whether written or oral, relative to
the matters discussed herein.  This Agreement may only be amended by a written
document signed by both Consultant and the Company.

     d.  INJUNCTIVE RELIEF.  Consultant acknowledges that it would be difficult
to fully compensate the Company for damages resulting from any breach by
Consultant of the provisions of 5 and/or 6 of this Agreement.  Accordingly, in
