                                        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, the trade name of Fibercor is used
for marketing water filtration products, and the trade name of Unitrol is used
for products sold in the endoscopy market. The Company has core technologies in
electronics, fibers, plastics, and chemical solutions, all of which were
internally developed.

INDUSTRY SEGMENTS
    Through March 31, 1997, the Company has been primarily engaged in a single
industry segment--medical devices and supplies. The Company also markets
filtration devices for industrial water purification applications.

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 form for use in virtually all types of
kidney dialysis machines. The U.S. hemodialysis patient population consumes
almost 35 million gallons of concentrates annually (estimate based on published
information on patient populations). Sales of concentrate products accounted for
more than 75 percent of all sales in this product group in each of the past 
three fiscal years.

    The Company introduced its first dialyzer (artificial kidney) - the
Renaflo-Registered Trademark- HDF 1350 dialyzer - in fiscal 1992. In fiscal
1993, the Company introduced the Primus-Registered Trademark- line of second
generation dialyzers in Europe, and in August 1994, the Company received FDA
market clearance to sell the Primus-Registered Trademark- dialyzer in the United
States. Dialyzers are a commodity product that require considerable sales volume
and low cost structure to be profitable. At the close of fiscal 1997, the
Company's share of the highly competitive dialyzer market was less than one
percent. As a result, in March 1997, the Company discontinued the
Primus-Registered Trademark- dialyzer line, taking a one-time restructuring
charge to write off all of the assets employed in the dialyzer business.  

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


                                          2
<PAGE>

hemodialysis. The Sonalarm-Registered Trademark- and the Minipump-TM- are sold
to end users and in component form to other manufacturers of blood processing
equipment.

    These dialysis products accounted for approximately 32 percent of the
Company's sales in fiscal 1997, 29 percent of product sales in fiscal 1996 and
33 percent of product sales in fiscal 1995.

    REPROCESSING PRODUCTS 
    Reprocessing products include the Renatron-Registered Trademark- Dialyzer
Reprocessing System and associated supplies, including Renalin-Registered
Trademark-, a cold sterilant solution that replaces formaldehyde,
gluteraldehyde, and bleach 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 use. 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. Data released by the Centers for Disease
Control ("CDC") indicate that, as of 1994, 81 percent of all U.S. hemodialysis
patients were treated in centers that reuse dialyzers. The CDC also reported
that 75 percent of all dialysis centers in the United States reuse dialyzers and
52 percent 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 one of the top selling
automated dialyzer reprocessing systems in the world. At March 31, 1997, the
Company had an installed customer base of more than 3,000 Renatron-Registered
Trademark- systems.

    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. ("Bard")
for $934,000 in cash. Manufacturing of the products was assimilated into the
Company's electronic device production facility in Minneapolis, Minnesota. The
endoscope reprocessing machine provides high level disinfection for flexible
endoscopes and is marketed to gastroenterology units of hospitals and ambulatory
care units. 

    In fiscal 1997, Peract-TM- 20, a peracetic acid-based liquid cold
sterilant/disinfectant for endoscope reprocessing, was introduced to the
international marketplace. The product was submitted to FDA for 510(k)
registration in February 1996, and the Company was still awaiting clearance as
of March 31, 1997.

    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-, is an
automated system for cleaning and sterilizing cardiovascular catheters for
subsequent reuse. The product was never introduced in the United States
marketplace.  In March 1997, in an effort to reduce expenses and focus resources
on profitable product areas, the Company discontinued the Cathetron-Registered
Trademark- system and CATHx-Registered Trademark- sterilant.  Assets related to
the Cathetron-Registered Trademark- business were written off as part of the
Company's restructuring charge.  

    Reprocessing products accounted for approximately 38 percent of product
sales in fiscal 1997, 34 percent of sales in 1996 and 32 percent of product
sales in fiscal 1995.

    CARDIOSURGERY PRODUCTS
    The primary products in this group at March 31, 1997, consisted of three
hollow fiber devices.

    OXYGENATORS 
    Since 1987, the Company has manufactured membrane oxygenators based on its
proprietary hollow fiber technology. An oxygenator is used by a perfusionist (a
technician who operates heart-lung bypass equipment) to replace the function of
the lungs during open-heart surgery. To date, the Company's oxygenators have
been used in over 600,000 open-heart procedures worldwide. The Company's first
generation oxygenator was sold exclusively


                                          3
<PAGE>

through Bard. from 1987 through March 31, 1997. Since March 31, 1997, this first
generation oxygenator has been available from the Company under the trade name
Minntech-TM- 400. In 1995, the Company introduced a second generation oxygenator
- - the Biocor-TM- 200 High Performance Oxygenator.

    From 1987 to 1997, the Company manufactured its first generation oxygenator
for exclusive worldwide distribution pursuant to an agreement with 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.  In April 1995, Bard and the Company entered into a new
agreement for the sale of the oxygenator whereby Bard agreed to purchase certain
minimum quantities of the oxygenator through March 31, 1997. The agreement also
allowed Bard to continue purchasing the oxygenator through June 30, 1997,
without any minimum purchase obligation. Bard had exclusive distribution rights
through March 31, 1997 and nonexclusive rights thereafter, and was restricted
from selling any other oxygenator until January 1, 1997. Bard's minimum purchase
obligation under the agreement for the period April 1, 1995 to March 31, 1997,
had a sales value to the Company of approximately $20 million. The Company does
not anticipate significant orders from Bard in the first quarter of fiscal 1998.
See "Significant Customers."

    The Biocor-TM- 200 was introduced in Europe in November 1995, and on March
7, 1997, the Company received FDA 510(k) clearance for the U.S. market for the
Biocor-TM-. The product incorporates the Company's proprietary weaving
technology and offers improved performance over its first generation oxygenator.
The compact design and reduced surface area of the device results in a low
priming volume - a feature that reduces set-up time for the perfusionist and can
reduce the need for donor blood. The Biocor-TM- 200 also provides a high gas
transfer rate with minimal pressure drop. The Company believes that the
consistent high performance characteristics of the device are equal or superior
to competing products.

    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 to 30 percent of all
open-heart procedures in the United States and to a lesser extent
internationally, and that such procedures require up to 140,000 hemoconcentrator
devices annually worldwide. At March 31, 1997, the Company believes it holds
more than a 70 percent share of the United States hemoconcentrator market.

    HEMOFILTERS
    The Renaflo-Registered Trademark- Hemofilter, introduced in fiscal 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. 

    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. The Company also 
signed a six-month supply agreement with Amicon whereby Amicon manufactured 
products for the Company to be sold in Europe. The Company began 
manufacturing the hemoconcentrator and hemofilter products in its Minneapolis 
facility in the first quarter of fiscal 1997. 

    Cardiosurgery products accounted for approximately 26 percent of the
Company's product sales in fiscal 1997, 34 percent of product sales in fiscal
1996, and 33 percent of product sales in fiscal 1995.

    WATER FILTRATION PRODUCTS
    There are two major products in this group:  Fiberflo-Registered Trademark-
Microfilter 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, 1997, water filtration
product sales accounted for 3.6 percent of the Company's product sales in fiscal
1997, 2.5 percent of product sales in fiscal 1996, and 2.2 percent of product
sales in fiscal 1995.


                                          4

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, 1997, the Company employed a
total of seven 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.

    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's
headquarters for its European operations in the Netherlands employed a total of
15 people in Europe at March 31, 1997. 

    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. Endoscope reprocessing
marketing programs are directed at gastroenterology nurses and physicians,
infection control and central sterile processing personnel, and hospital and
clinic administrators. Water filtration marketing programs are directed at
distributors and large OEMs. 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.

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 151 patents worldwide (including 42 U.S.
patents) covering its products or components thereof. At March 31, 1997, the
Company also had a total of 100 pending patent applications in the United States
and in foreign countries. The Company also holds rights under 191 trademark
registrations worldwide and has 86 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, 1997.

SIGNIFICANT CUSTOMERS 
    The Company's five largest customers in fiscal 1997 accounted for
approximately 29 percent of total sales. Sales of oxygenators to Bard accounted
for approximately 10 percent of product sales in fiscal year 1997, and 20
percent or more of product sales in fiscal 1996 and 1995. Bard agreed to
purchase certain minimum quantities of the


                                          5
<PAGE>

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 Company does not anticipate significant
orders from Bard in the first quarter of fiscal 1998 (See
"Products--Cardiosurgery Products--Oxygenators").

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 Inc., Gambro
(a division of CGH Medical), and Fresenius Medical Care 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 new Biocor-TM- oxygenator and hemoconcentrators are sold by
its own direct sales force and by a network of independent medical distributors.
Bard was the exclusive distributor of the Company's first generation membrane
oxygenator through March 31, 1997, and has nonexclusive distribution rights
through June 30, 1997 (See "Products-Cardiosurgery Products-Oxygenators").  The
first generation oxygenator, now known as the Minntech-TM- 400, has also been
available directly from the Company since March 31, 1997.  Besides Bard, the
Company's major competitors in the oxygenator market are Medtronic, Inc., Cobe
Laboratories Inc. (a division of CGH Medical), Baxter International, Inc.,
Terumo Corporation and Avecor Cardiovascular, Inc. The major competitors in the
hemoconcentrator market are CGH Medical and Baxter International, 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 Company products, such as dialyzer and endoscope reprocessing
products, hemoconcentrators, and the Renapak-Registered Trademark- Concentrate
Manufacturing System. 

    There is a growing trend in the dialysis industry whereby manufacturers of
supplies are acquiring chains of dialysis treatment centers. These
manufacturers, in effect, have a built-in customer base for their products. 
However, the Company views its manufacturer-only status as a competitive market
advantage. The Company believes that many dialysis treatment providers do not
want to purchase hemodialysis supplies from manufacturers who also provide
dialysis services and are, in effect, their competitors.  

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.



                                          6
<PAGE>

    As of March 31, 1997, 20 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 $9,680,000 in
research and development as follows: fiscal 1997 - $3,424,000; fiscal 1996 -
$3,123,000; and fiscal 1995 - $3,133,000. Such costs represented 5.2 percent ,
4.8 percent and 5.6 percent of revenues, respectively, in each such period.

    The Company's current research and development efforts are directed toward
reprocessing applications, blood filtration and oxygenation technologies, cold
sterilant/ disinfection applications, and water filtration.

GOVERNMENT REGULATION 
    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 U.S. 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 (GMP)
regulations under which the FDA conducts periodic inspections to verify
compliance. Further, the GMP's impose 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. In
some cases, before commencing clinical trials, the Company must apply for an
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
Minneapolis, 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 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. 

    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.

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

RESULTS OF OPERATIONS 
    REVENUES 
    Revenues in fiscal year 1997 increased by $1,138,000, or 1.8 percent over
fiscal 1996 revenues due primarily to increased unit sales of reprocessing
products and dialysis supplies and devices. Sales of dialysis reprocessing
products increased by 17 percent for the current fiscal year with endoscope and
catheter reprocessing showing declines. Dialysis supply and device (excluding
dialyzer) sales increased 9 percent for the current fiscal year.

    Revenues from cardiosurgery products during fiscal 1997 declined 24 percent
from the prior fiscal year reflecting the gradual phase out under the oxygenator
contract. Sales of oxygenators to Bard accounted for 10 percent of total company
revenues in fiscal year 1997 compared to 20 percent in fiscal year 1996. The
Company's supply contract with Bard expires June 30, 1997, and management does
not anticipate material sales to Bard in fiscal year 1998. Management expects
that sales of the Company's new oxygenator will largely offset the decline in
product sales from the Bard contract. On March 7, 1997, the new Biocor-TM- 200
High Performance Oxygenator received FDA clearance to market, and the Company
began selling it in the U.S. shortly thereafter. Sales of this product commenced
in Europe in November 1995.

    Total revenues in fiscal year 1996 increased by $8,587,000, or 15 percent
over fiscal year 1995 revenues due primarily to increased unit sales of
dialyzer reprocessing and endoscope reprocessing products and increased sales of
cardiosurgery products. Sales of cardiosurgery products for the fiscal year 1996
grew 22 percent due to increased unit sales of hemoconcentrators and hemofilters
which more than offset a small decline in oxygenator sales. Product lines
acquired in the first quarter of the 1996 fiscal year contributed to the growth
of cardiosurgery product sales. Product price increases in fiscal year 1996 did
not have a significant impact on revenues.

    Changes in foreign currency exchange rates did not have a significant
impact on the Company's revenues in fiscal years 1997, 1996, and 1995.

    Product sales have grown at a compound annual rate of 12 percent over the
past three years. The following table indicates sales and percent of total sales
by product group for each of the last three fiscal years:

    GROSS MARGINS
    Gross profit from product sales in fiscal 1997 was $27,414,000, or 41.6
percent of net product sales, compared to $26,661,000, or 41.2 percent, in
fiscal 1996 and $24,108,000, or 43.1 percent, in fiscal 1995. The increase in
gross margin in fiscal 1997 resulted primarily from increased sales of higher
margin reprocessing products. The decrease in gross margin in fiscal 1996 was
due primarily to lower margins on certain hollow fiber products. High dialyzer
manufacturing costs depressed gross margins in each of fiscal years 1997, 1996,
and 1995.

    RESEARCH AND DEVELOPMENT 
    Research and development expenses in fiscal 1997 were $3,424,000 or 5.2
percent of revenues, compared to $3,123,000, or 4.8 percent of revenues, in
fiscal 1996 and $3,133,000 or 5.6 percent of revenues in fiscal 1995. 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 1998 will approximate 5 1/2 - 6 percent of revenues. 

    SELLING, GENERAL AND ADMINISTRATIVE 
    Selling, general, and administrative expenses as a percentage of total
revenues were 26.4 percent in fiscal 1997 compared to 23.7 percent in fiscal
1996 and 21.3 percent in fiscal 1995. The higher costs in fiscal years 1997 and


                                          12
<PAGE>

1996 were due primarily to increases in sales staffs and expanded marketing
efforts in Europe and Japan (in 1996). Additionally, expenses in the United
States have increased due to the changing marketing requirements in the
Company's cardiosurgery business.

    RESTRUCTURING AND UNUSUAL ITEMS
    The Company recorded pre-tax charges for restructuring and unusual items of
$9,569,000 in the fourth quarter of fiscal 1997. These charges reflect the
discontinuation of the Primus-Registered Trademark- dialyzer and Cathetron-TM-
catheter reprocessing system combined with expenses associated with the
departure of the Company's founder, Dr. Louis C. Cosentino, as Chairman, Chief
Executive Officer, and President.  Management determined that the dialyzer
product line does not fit within the long-term strategy of the Company due to
the competitive nature of the business and high sales volumes required to be
profitable. Key aspects of the dialyzer related charges are fixed asset,
inventory, and intellectual property write-downs to estimated net realizable
values. 

    INCOME TAXES 
    The tax provision for fiscal 1997 reflects a benefit of $700,249, an
effective tax rate of 16.1 percent. The Company's effective income tax rate in
fiscal 1996 and 1995 were 36.5 percent and 35.8 percent, respectively. The 
company benifited from deductible losses related to investments in foreign 
subsidiaries in fiscal years 1996 and 1995.  The fiscal 1997 effective rate 
is low primarily because no tax benifit was recorded for operating losses at 
foreign subsidiaries. The Company's effective income tax rate may vary in fiscal
1998, depending upon the operating results of its foreign subsidiaries.

    NET EARNINGS 
    The Company recorded a net loss in fiscal 1997 of $(3,372,000), or $(0.51)
per share, compared to earnings of  $4,308,000, or $0.62 per share, in fiscal
1996 and $5,920,000,or $0.90 per share, in fiscal 1995. The net loss in fiscal
1997 was due restructuring charges related primarily to the discontinuation of
the Primus-Registered Trademark- dialyzer line. Prior to the restructuring
charge, the Company had net income of $2,922,000, or $0.44 per share, in fiscal
1997.

    The decrease in earnings and net margin in fiscal 1996 was due to higher 
operating expenses, lower gross margin, and fiber production scale-up losses 
of $936,000 incurred in the second quarter. The increase in earnings in 
fiscal 1995 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:

     MARCH 31                         1997          1996           1995

    Cash dividends paid              667,471        652,542        623,250

    The decrease in cash, working capital, and cash flow from operations in
fiscal 1997 is primarily attributable to operating the Primus-Registered
Trademark- dialyzer  product line at a loss during the year.  The Company's
current ratio at March 31, 1997 was 2.8 compared to 4.2 at March 31, 1996. The
Company borrowed $4,000,000 against its $10,000,000 bank line of credit in
September 1996. As of March 31, 1997, the outstanding balance was reduced to
$3,000,000 and to $1,000,000 on June 19, 1997. The bank line of credit allows
the Company to borrow on an unsecured basis at either the prime rate of interest
(8.25 percent as of March 31, 1997) or at an indexed London Interbank Offered
Rate (LIBOR).

    The Company expended a total of $5,208,000 for plant improvements and
equipment in fiscal 1997, compared to $4,333,000 in fiscal 1996 and $3,573,000
in fiscal 1995. The Company plans to invest approximately $3,800,000


                                          13
<PAGE>

in capital equipment in fiscal 1998. During the first quarter of fiscal 1996,
the Company acquired a group of hollow fiber product lines for $1,402,000 in
cash. The assets acquired included inventory, equipment, and goodwill.

    During the past three years, proceeds from stock options exercised provided
a total of $3,375,259 in equity capital as follows: fiscal 1997--$486,794;
fiscal 1996--$1,979,059; and fiscal 1995--$909,406.

    The Company believes that its strong financial condition at March 31, 1997,
along with anticipated cash flows from operations, will be sufficient to meet
its working capital and capital equipment needs in fiscal 1998.

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 Netherlands-based subsidiary
are invoiced and paid in several currencies, including Dutch guilders, 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.

RISK FACTORS
   Certain statements made in this Annual Report on Form 10-K, are
forward-looking statements that involve risks and uncertainties, and actual
results may differ. Factors that could cause actual results to differ include
those identified below.

    COMPETITION; UNCERTAINTY OF TECHNOLOGICAL CHANGE.  The markets in which the
Company competes are highly competitive and are characterized by innovation and
technological change. The Company currently competes in each area of the
Company's business with a number of companies that have capital resources,
research and development staffs, facilities, experience in conducting clinical
trials and obtaining regulatory approvals, and experience in manufacturing and
marketing medical supplies and devices that are significantly greater than those
of the Company. In addition, there are several companies developing new
technologies which may reduce the demand for the Company's existing products,
such as minimally invasive techniques in open heart surgery which may not
require the use of oxygenators. There can be no assurance that the Company's
competitors will not succeed in developing technologies and products that are
more effective than any that are being developed by the Company or that would
render the Company's products obsolete or noncompetitive. In addition, certain
of the Company's competitors may achieve patent protection, regulatory approval
or product commercialization that would limit the Company's ability to compete.
The Company's inability to compete successfully could have a material adverse
effect on its business, financial condition, and results of operations.
  
    RELIANCE ON PATENTS AND PROPRIETARY TECHNOLOGY.  The Company relies heavily
on proprietary technology, which it protects primarily through licensing
arrangements, patents, trade secrets, and proprietary know-how. The Company
holds patents and has pending patent applications that cover certain aspects of
its technology. There can be no assurance that any pending or future patent
applications will be granted or that any current or future patents, regardless
of whether the Company is an owner or a licensee of such patent, will not be
challenged, rendered unenforceable, invalidated or circumvented or that the
rights granted thereunder or under its licensing agreements will provide a
competitive advantage to the Company. There can also be no assurance that the
Company's trade secrets or non-disclosure agreements will provide meaningful
protection of the Company's proprietary information.  Furthermore, there can
also be no assurance that others will not independently develop similar
technologies or duplicate any technology developed by the Company or that the
Company's technology will not infringe upon patents or other rights owned by
others. The Company's inability to maintain its proprietary rights would have a
material adverse effect on its business, financial condition, and results of
operations.

    LACK OF MARKET ACCEPTANCE. The Company's principal products are based upon
innovative medical concepts.  The Company believes that market acceptance of
these products will depend, in part, on the Company's ability to convince the
medical community of the safety, efficacy, convenience, and cost effectiveness
of these products as compared to existing competitive products. Market
acceptance will further depend on the Company's ability to gain acceptance by
the medical community of the use of its products. There can be no assurance that
medical professionals will readily adopt new products or approaches,
particularly when certain competitors of the Company provide a more complete
product mix than that offered by the Company.  The Company's inability to gain
market acceptance for its recently introduced Biocor-TM- 200 oxygenator and
other products would have a material adverse effect on the Company's business,
financial condition, and results of operations.
  

                                          14
<PAGE>

    LITIGATION; POTENTIAL FOR ADVERSE OUTCOMES. The medical supply and device
market is characterized by frequent and substantial intellectual property
litigation. Intellectual property litigation is complex and expensive, and the
outcome of such litigation is difficult to predict. A finding against the
Company could have a material adverse effect on the Company's business,
financial condition, and results of operations. 

    GOVERNMENT REGULATION. In the United States, the United States Food and
Drug Administration (the "FDA") regulates the sale of medical supplies and
devices as well as manufacturing procedures, labeling, and recordkeeping with
respect to such products. The process of obtaining marketing clearances and
approvals from the FDA for new products can be time consuming and expensive, and
there is no assurance that such clearances or approvals will be granted or that
FDA review will not involve delays that would adversely affect the Company's
ability to commercialize its products. The FDA requires that a new product
secure either a 510(k) clearance or an approved PMA, depending upon its
classification, prior to marketing in the United States. The Company's products
are currently sold under a 510(k) clearance, which is available for products
demonstrated to be substantially equivalent to products that are already
commercially available. The 501(k) clearance process typically takes several
months and may require the submission of supporting laboratory or clinical data.
No assurance can be given that the Company will receive FDA marketing approval
for new products on a timely basis, or at all. Even if regulatory approvals to
market a product are obtained from the FDA, such approvals may entail
limitations on the indicated uses of the product. Product approvals by the FDA
can also be withdrawn due to failure to comply with regulatory requirements or
the occurrence of unforeseen problems following initial approval. The FDA could
also limit or prevent the manufacture or distribution of the Company's products
and has the power to require the recall of such products. A product recall,
whether voluntary or mandated by the FDA, would have a material adverse effect
on the Company, particularly at the early stage of market introduction. FDA
regulations depend heavily on administrative interpretation, and there can be no
assurance that future interpretations made by the FDA or other regulatory
bodies, with possible retroactive effect, will not adversely affect the Company.

    The FDA, various state agencies, and foreign regulatory agencies inspect
the Company from time to time to determine whether the Company is in compliance
with various regulations relating to manufacturing practices, validation,
testing, quality control and product labeling. For example, the United States
Environmental Protection Agency regulates the chemical sterilants used in the
Company's water filtration product line. A determination that the Company is in
violation of such regulations could lead to imposition of civil penalties,
including fines, product recall orders or product seizures, and, in extreme
cases, criminal sanctions.  

    International regulatory bodies often establish varying regulations
governing products standards, packaging requirements, labeling requirements,
import restrictions, tariff regulations, duties and tax requirements.  As a
result of the Company's sales in Europe, the Company was required to be
certified as ISO 9001 compliant and to receive CE mark certification. Failure to
maintain CE mark certification would have a material adverse effect on the
Company's business, financial condition, and results of operations.

    LIMITATIONS ON THIRD-PARTY REIMBURSEMENT.  The Company's ability to sell
its products depends in part on the extent to which reimbursement for the cost
of such products and related treatments are available to patients under domestic
and foreign governmental health programs, private health insurance, managed care
organizations, workers' compensation insurers, and other similar programs. Over
the past decade, the cost of health care has risen significantly, and there have
been numerous proposals by legislators, regulators, and third-party health care
payors to curb these costs. In addition, certain health care providers are
moving towards a managed care system in which such providers contract to provide
comprehensive health care for a fixed cost per person.  The Company is unable to
predict what changes will be made in the reimbursement methods utilized by
third-party health care payors. In addition, hospitals and other health care
providers have become increasingly price competitive and, in some instances,
have put pressure on medical suppliers to lower their prices.  Any reductions in
coverage or price limitations by third-party payors could have a material
adverse effect on the Company's business, financial condition, and results of
operations.

    PRODUCT LIABILITY. The medical supply and device industry has been
historically litigious and the Company faces an inherent business risk of
financial exposure to product liability claims in the event that the use of its
products results in personal injury.  Since the Company's principal products are
designed to be used in connection with medical procedures on the human body,
manufacturing errors or design defects could result in an unsafe condition,
injury or death to the patient, and could result in a recall of the Company's
products and substantial


                                          15
<PAGE>

monetary damages. There can be no assurance that the Company will not experience
losses due to product liability claims in the future. Although the Company
currently maintains liability insurance, there can be no assurance that the
coverage limits of the Company's insurance policies will be adequate. Such
insurance is expensive, difficult to obtain, and may not be available in the
future on acceptable terms, or at all. Any claims against the Company,
regardless of their merit or eventual outcome, could have a material adverse
effect upon the Company's business financial condition, and results of
operations.

    ACQUISITION OF CUSTOMERS BY COMPETITORS OF THE COMPANY. A significant
percentage of dialysis treatment centers nationwide are owned by competitors of
the Company. Accordingly, the Company may face difficulty in selling its
dialysis products to these centers. Additionally, a competitor has recently
acquired a number of companies that provide contract perfusion services to
hospitals.  Although the Company believes that it is too early to assess the
long-term effects of these acquisitions on its business, the Company may face
difficulty in selling its cardiosurgery products to perfusionists employed by
these companies or to hospitals or clinics that contract with them. These
acquisitions (or other acquisitions by the Company's competitors) could have a
material adverse effect on the Company's business, financial condition, and
results of operations.

    DEPENDENCE ON DISTRIBUTOR SALES. Sales to distributors constitute a
significant portion of the Company's business both in the U.S. and foreign
markets. There can be no assurance that the Company will be able to maintain its
relationship with distributors, or, if these relationships terminate, that new
distributors will be found. The loss of a significant distributor could have a
material adverse effect on the Company's business, financial condition and
results of operations if a new distributor (or other suitable sales
organization) could not be found on a timely basis.

    INTERRUPTION IN SOURCES OF SUPPLY.  The fiber used in the Company's
oxygenators is purchased from a single source. If this source of supply becomes
unavailable, then there can be no assurance that the Company would be able to
find an acceptable substitute supplier. In addition, high demand for
polycarbonate products by various industries has at times caused temporary
shortages of their supply. Any significant interruption in the supply of these
products could have a material adverse effect on the Company's business,
financial condition, and results of operations.

    ENVIRONMENTAL COMPLIANCE. In the ordinary course of its manufacturing
process, the Company uses various chemical solvents and other regulated
substances. Although the Company is not aware of any claim involving violation
of environmental or occupational health and safety laws or regulations, there
can be no assurance that such a claim may not arise in the future, which could
have a material adverse effect on the Company's business, financial condition,
and results of operations.

    CURRENCY RISK. Approximately 20 percent of the Company's business is
transacted in foreign markets. Long-term changes or short-term fluctuations in
currency exchange rates could have a material adverse effect on the Company's
business, financial condition, and results of operations.

    DEPENDENCE ON SIGNIFICANT CUSTOMERS. The Company's five largest customers
in fiscal 1997 accounted for 29 percent of its total sales. The loss of one or
more of these customers could have a material adverse effect on the Company's
business, financial condition, and results of operations. The Company's
oxygenator supply contract with Bard ended June 30, 1997. Although the Company
plans to supplant the lost revenues from Bard under this contract with sales of
its recently introduced Biocor TM 200 oxygenator, there can be no assurance that
these plans will be realized.

    DEPENDENCE ON KEY PERSONNEL.  The Company's success depends in large part
on its ability to attract and retain highly qualified scientific, technical,
management, and marketing personnel. Competition for such personnel is intense
and there can be no assurance that the Company will be able to attract and
retain the personnel necessary for the development and operation of its
business.  The loss of the services of key personnel could have a material
adverse effect on the Company's business, financial condition, and results of
operations. 

    POSSIBLE VOLATILITY OF SHARE PRICE. Market prices for securities of medical
technology companies are highly volatile and the trading price of the Company's
Common Stock could be subject to significant fluctuations in response to
quarterly variations in operating results, announcements of technological
innovations by the Company or its competitors, government regulation, and other
events or factors, including the various risk actors discussed herein. In
addition, market prices of securities of medical technology companies have from
time to time experienced extreme price and volume fluctuations, which may be
unrelated to the operating performance of particular


                                          16
<PAGE>

companies. These broad market fluctuations may materially adversely affect the
market price of the Company's Common Stock.

    ANTI-TAKEOVER CONSIDERATIONS.  The Board of Directors of the Company has
the authority, without any action by the shareholders, to fix the rights and
preferences of any shares of the Company's Preferred Stock to be issued from
time to time. In addition, as a Minnesota corporation, the Company is subject to
certain anti-takeover provisions of the Minnesota Business Corporation Act (the
"MBCA"). The authority of the Board with regard to the Preferred Stock and the
provisions of the MBCA could have the effect of delaying, deferring or
preventing a change in control of the Company, may discourage bids for the
Company's Common Stock at a premium over the then prevailing market price of the
Common Stock, and may adversely effect the market price of, and the voting and
other rights of the holders of, Common Stock.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE

    Grant Thornton LLP, the Company's independent accountants since 1974, was 
dismissed on January 30, 1995, and Price Waterhouse LLP was appointed as the 
Company's new independent accountants. Grant Thornton's report on the financial
statements for the year ended March 31, 1994, was unqualified. Price 
Waterhouse's report on the financial statements for the years ended March 31, 
1995 and 1996 were unqualified. There have been no disagreements with Grant 
Thornton LLP or Price Waterhouse LLP on any matter of accounting principles 
or practices, financial statement disclosure, or auditing scope or procedure. 
There have occurred no "reportable events" as defined in Item 304(a) of 
Regulation S-K. The decision to change accountants was recommended by the 
Audit Committee of the Company's Board of Directors and approved by the Board 
of Directors.

                                 MINNTECH CORPORATION
                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    BUSINESS DESCRIPTION
    Minntech Corporation is a leader in developing, manufacturing and marketing
medical devices, sterilants and water filtration products. The Company's
products are used in kidney dialysis, open-heart surgery, endoscopy, and in the
preparation of pure water for medical, industrial and laboratory use.

    CONSOLIDATION POLICY
    The consolidated financial statements include the accounts of the Company,
its majority-owned subsidiary and its wholly-owned subsidiaries. All
intercompany balances and transactions have been eliminated in consolidation.

    USE OF ESTIMATES
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    REVENUE RECOGNITION
    Sales are recognized at the time products are shipped. The Company allows
customers to return products for credit upon written authorization from the
Company.

    Contract revenues derived from development and marketing agreements are
recorded as earned based on the performance requirements of the contract.

    CASH AND CASH EQUIVALENTS
    The Company considers all highly liquid temporary investments with original
maturities of three months or less to be cash  equivalents. Cash and cash
equivalents consisted of:

                                               ------------   ------------

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

    Money market mutual funds are stated at fair value, which approximates cost
at March 31, 1997 and 1996.

    MARKETABLE SECURITIES
    The Company accounts for marketable securities in accordance with the
provisions of Statement of Financial Accounting Standards No. 115, "Accounting
for Certain Investments in Debt and Equity Securities."

1997 and 1996, the adjusted cost of the funds exceed fair market value. The
unrealized holding losses, net of income taxes, are reported as a reduction in
stockholders' equity.

by the first-in, first-out method.

                                               ------------   ------------

    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
    The Company accounts for income taxes in accordance with the provisions of
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes."

    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.

    ADOPTION OF FAS 123
    Statement of Financial Accounting Standard No. 123, "Accounting for
Stock-Based Compensation," requires companies to measure employee stock
compensation plans based on the fair value method of accounting. However, the
Statement allows the alternative of continued use of Accounting Principles Board
(APB) Opinion No. 25, "Accounting for Stock Issued to Employees," with pro forma
disclosure of net income and earnings per share determined as if the fair-value
based method had been applied in measuring compensation cost. The Company
adopted the new standard in fiscal 1996 and elected the continued use of APB
Opinion No. 25.

NOTE 2--RESTRUCTURING AND UNUSUAL ITEMS

    In the fourth quarter of fiscal 1997, the Company adopted a restructuring
plan designed to reduce its cost structure and improve its competitive position
primarily through the discontinuation of two unprofitable product lines--the
Primus-Registered Trademark- dialyzer and Cathetron-Registered Trademark-
catheter reprocessing system. In addition, the charge provided for costs
associated with the departure of the Company's founder as Chairman, Chief
Executive Officer and President. The restructuring charge totaled $9,569,000
before taxes and $6,294,000 after taxes.

    The Primus-Registered Trademark- dialyzer related charges totaled
$7,282,000 and consist of write-downs of inventory, $4,191,000; fixed assets,
$2,930,000; and intellectual property, $161,000. Charges related to the
Cathetron-Registered Trademark- catheter reprocessing system total, $574,000;
and relate to a provision for anticipated sales returns and write-down of
inventory. Included in the charge is $1,229,000 to provide for severance and
anticipated future pension costs related to the departure of the Company's

   The fair value of options granted under the Company's fixed stock option
plans during fiscal 1997 and 1996 was estimated on the dates of grant using the
Black-Scholes options-pricing model.  The assumptions for fiscal 1997 and 1996
were as follows:

     FY ENDED MARCH 31                                    1997         1996

     Risk free interest rates                          6.0 - 6.6%   5.4 - 6.9%
     Expected life                                      5.1 years    5.1 years

     Expected dividends                                        1%           1%

   Pro forma compensation cost related to shares purchased under the Employee
Stock Purchase Plan is measured based on the discount from market value. The
effects of applying FAS 123 in this pro forma disclosure are not indicative of
future pro forma effects. FAS 123 does not apply to awards granted prior to 
fiscal 1996 nor to awards anticipated in future years with exception to the 
fiscal 1997 pricing.

Company matches 10 percent of employee contributions to a maximum of 6/10ths of
1 percent of compensation. The Company also makes annual profit sharing
contributions to the plan at the discretion of the Board of Directors. The

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
generally accepted auditing standards which require that we plan and perform the

in the aggregate, may be issued pursuant to Restricted Stock or Deferred Stock
awards.

    Subject to paragraph (b)(iv) of Section 6 below, if any shares that have

Restricted Stock or Deferred Stock award granted hereunder are forfeited or such
award otherwise terminates without a payment being made to the participant, such
shares shall again be available for distribution in connection with future
awards under the Plan.

    In the event of any merger, reorganization, consolidation, 
recapitalization, stock dividend, other change in corporate structure 
affecting the Stock, or spin-off or other distribution of assets to 
shareholders, such substitution or adjustment shall be made in the aggregate 
number of shares reserved for issuance under the Plan, in the number and 
option price of shares subject to outstanding options granted under the 
Plan, and in the number of shares subject to Restricted Stock or Deferred 
Stock awards granted under the Plan as may be determined to be appropriate 
by the Committee, in its sole discretion, provided that the number

                                          4
<PAGE>

of shares subject to any award shall always be a whole number.  Such adjusted
option price shall also be used to determine the amount payable by the Company
upon the exercise of any Stock Appreciation Right associated with any Option.

    SECTION 4.  ELIGIBILITY.

    Officers, other key employees of the Company and Subsidiaries and
Non-Employee Directors, and consultants and other persons having a contractual
relationship with the Company or its Subsidiaries who are responsible for or
contribute to the management, growth and/or profitability of the business of
the Company and its Subsidiaries are eligible to be granted Stock Options,
Stock Appreciation Rights, Restricted Stock or Deferred Employee Stock awards
under the Plan. Except for Non-Employee Directors, whose participation in the
Plan shall be limited as provided in paragraph (k) of Section 5, the optionees
and  participants under the Plan shall be selected from time to time  by the
Committee, in its sole discretion, from among those  eligible, and the Committee
shall determine, in its sole  discretion, the number of shares covered by each
award.

    SECTION 5.  STOCK OPTIONS.

    Any Stock Option granted under the Plan shall be in such form as the
Committee may from time to time approve.

    The Stock options granted under the Plan may be of two types: (i)
Incentive Stock Options and (ii) Non-Qualified Stock  Options.  No Incentive
Stock Options shall be granted under the Plan after July 25, 1999.

    The Committee shall have the authority to grant any optionee Incentive
Stock options, Non-Qualified Stock options, or both types of options (in each
case with or without Stock Appreciation Rights).  To the extent that any option
does not qualify as an Incentive Stock Option, it shall constitute a separate
Non-Qualified Stock option.

    Anything in the Plan to the contrary notwithstanding, no term of this Plan
relating to Incentive Stock Options shall be interpreted, amended or altered,
nor shall any discretion or authority granted under the Plan be so exercised,
so as to disqualify either the Plan or any Incentive Stock Option under
Section 422 of the Code.  The preceding sentence shall not preclude any
modification or amendment to an outstanding Incentive Stock Option, whether or
not such modification or amendment results in disqualification of such Option
as an Incentive Stock Option, provided the optionee consents in writing to the
modification or amendment.


                                          5
<PAGE>

    Options granted under the Plan shall be subject to the following terms and
conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the  Plan, as the Committee shall deem desirable.

    (a)  OPTION PRICE.  The option price per share of Stock purchasable under 
a Stock Option shall be determined by the Committee at the time of grant.  In 
no event shall the option price per share of Stock purchasable under an 
Incentive Stock Option or a Non-Qualified Stock Option be less than 100% of 
the Fair Market Value of the Stock on the date of the grant of the option.  
If an employee owns or is deemed to own (by reason of the attribution rules 
applicable under Section 425(d) of the Code) more than 10% of the combined 
voting power of all classes of stock of the Company or any Parent 
Corporation or Subsidiary and an Incentive Stock Option is granted to such 
employee, the option price shall be no less than 110% of the Fair Market 
Value  of the Stock on the date the option is granted.

    (b)  OPTION TERM.  The term of each Stock option shall be fixed by the
Committee, but no Incentive Stock Option shall be exercisable more than ten
years after the date the option is granted.  If an employee owns or is deemed
to own (by reason of the attribution rules of Section 425(d) of the Code) more
than 10% of the combined voting power of all classes of stock of the Company
or any Parent Corporation or Subsidiary and an Incentive Stock Option is
granted to such employee, the term of such option shall be no more than five
years from the date of grant.

(c) EXERCISABILITY. Stock Options shall be exercisable at such time or times as
    determined by the Committee at or after grant.  If the Committee provides,
    in its discretion, that any option is exercisable only in installments, the
    Committee may waive such installment exercise provisions at any time.
    Notwithstanding the foregoing or any other provision of this Plan, unless
    the Stock Option Agreement provides otherwise, (1) any Stock Option granted
    under this Plan on or prior to September 26, 1996 (including options
    granted to Non-Employee Directors), that shall not have previously expired
    shall be immediately exercisable in full, without regard to any installment
    exercise provisions, for a period specified by the Company, but not to
    exceed sixty (60) days, prior to the occurrence of any of the following
    events:  (i) dissolution or liquidation of the Company other than in
    conjunction with a bankruptcy of the Company or any similar occurrence,
    (ii) any merger, consolidation, acquisition, separation, reorganization, or
    similar occurrence, where the Company will not be the surviving entity or
    (iii) the transfer of substantially all of the


                                          6
<PAGE>

    assets of the Company or 75% or more of the outstanding Stock of the
    Company and, in addition, (2) any Stock Option granted under this Plan,
    whether prior to, on or after September 26, 1996 (including options granted
    to Non-Employee Directors), that shall not have previously expired shall be
    immediately exercisable in full, without regard to any installment exercise
    provisions, upon the occurrence of a Change in Control.  For purposes of
    this Plan, a "Change in Control" of the Company shall be deemed to occur if
    any of the following occur:

              (1)  Any "person" (as such term is used in Sections 13(d) and
         14(d) of the Exchange Act) acquires or becomes a "beneficial owner"
         (as defined in Rule 13d-3 or any successor rule under the Exchange
         Act), directly or indirectly, of securities of the Company
         representing 30% or more of the combined voting power of the Company's
         then outstanding securities entitled to vote generally in the election
         of directors ("Voting Securities"), provided, however, that the
         following shall not constitute a Change in Control pursuant to this
         paragraph (c)(1):

                   (A)  any acquisition or beneficial ownership by the Company
              or a Subsidiary;

                   (B)  any acquisition or beneficial ownership by any employee
              benefit plan (or related trust) sponsored or maintained by the
              Company or one or more of its Subsidiaries;

                   (C)  any acquisition or beneficial ownership by any
              corporation with respect to which, immediately following such
              acquisition, more than 70% of both the combined voting power of
              the Company's then outstanding Voting Securities and the Stock of
              the Company is then beneficially owned, directly or indirectly,
              by all or substantially all of the persons who beneficially owned
              Voting Securities and Stock of the Company immediately prior to
              such acquisition in substantially the same proportions as their
              ownership of such Voting Securities and Stock, as the case may
              be, immediately prior to such acquisition;

              (2)  A majority of the members of the Board of Directors of the
         Company shall not be Continuing Directors.  "Continuing Directors"
         shall mean:  (A) individuals who, on the date hereof, are directors


                                          7
<PAGE>

         of the Company, (B) individuals elected as directors of the Company
         subsequent to the date hereof for whose election proxies shall have
         been solicited by the Board of Directors of the Company or (C) any
         individual elected or appointed by the Board of Directors of the
         Company to fill vacancies on the Board of Directors of the Company
         caused by death or resignation (but not by removal) or to fill
         newly-created directorships;

              (3)  Approval by the shareholders of the Company of a
         reorganization, merger or consolidation of the Company (other than a
         merger or consolidation with a subsidiary of the Company) or a
         statutory exchange of outstanding Voting Securities of the Company,
         unless immediately following such reorganization, merger,
         consolidation or exchange, all or substantially all of the persons who
         were the beneficial owners, respectively, of Voting Securities and
         Stock of the Company immediately prior to such reorganization, merger,
         consolidation or exchange beneficially own, directly or indirectly,
         more than 70% of, respectively, the combined voting power of the then
         outstanding voting securities entitled to vote generally in the
         election of directors and the then outstanding shares of common stock,
         as the case may be, of the corporation resulting from such
         reorganization, merger, consolidation or exchange in substantially the
         same proportions as their ownership, immediately prior to such
         reorganization, merger, consolidation or exchange, of the Voting
         Securities and Stock of the Company, as the case may be; or

              (4)  Approval by the shareholders of the Company of (x) a
complete liquidation or dissolution of the Company or (y) the sale or other
disposition of all or substantially all of the assets of the Company (in one or
a series of transactions), other than to a corporation with respect to which,
immediately following such sale or other disposition, more than 70% of,
respectively, the combined voting power of the then outstanding voting
securities of such corporation entitled to vote generally in the election of
directors and the then outstanding shares of common stock of such corporation is
then beneficially owned, directly or indirectly, by all or substantially all of
the persons who were the beneficial owners, respectively, of the Voting
Securities and Stock of the Company immediately prior to such sale or other
disposition in substantially the same proportions as their ownership,
immediately prior to such sale or other disposition, of the Voting Securities
and Stock of the Company, as the case may be.



                                          8

    (d)  METHOD OF EXERCISE.  Stock Options may be exercised in whole or in
part at any time during the option period by giving written notice of exercise
to the Company specifying the number of shares to be purchased.  Such notice
shall be accompanied by  payment in full of the purchase price, either by
certified or bank check, or by any other form of legal consideration deemed
sufficient by the Committee and consistent with the Plan's purpose and
applicable law, including promissory notes or a properly executed exercise
notice together with irrevocable instructions to a broker acceptable to the
Company to promptly deliver to the Company the amount of sale or loan proceeds
to pay the exercise price.  As determined by the Committee, in its sole
discretion, payment in full or in part may also be made in the form of
unrestricted Stock already owned by the optionee or, in the case of the exercise
of a Non-Qualified Stock Option, Restricted Stock or Deferred Stock subject to
an award hereunder (based, in each case, on the Fair Market Value of the Stock
on the date the option is exercised, as determined by the Committee),
provided, however, that, in the case of an Incentive Stock Option, the right to
make a payment in the form of already owned shares may be authorized only at
the time the option is granted, and provided further that in the event payment
is made in the form of shares of Restricted Stock or a Deferred Stock award,
the optionee will receive a portion of the option shares in the form of, and in
an amount equal to, the Restricted Stock or Deferred Stock award tendered as
payment by the optionee.  If the terms of an option so permit, an optionee may
elect to pay all or part of the option exercise price by having the Company
withhold from the shares of Stock that would otherwise be issued upon exercise
that number of shares of Stock having a Fair Market Value equal to the aggregate
option exercise price for the shares with respect to which such election is
made.  No shares of Stock shall be issued until full payment therefor has been
made.  An optionee shall generally have the rights to dividends and other rights
of a shareholder with respect to shares subject to the option when the optionee
has given written notice of exercise, has paid in full for such shares, and, if
requested, has given the representation described in paragraph (a) of Section
12.


                                          9
<PAGE>

    (e)  NON-TRANSFERABILITY OF OPTIONS. No Stock Options shall be transferable
by the optionee otherwise than by will or by the laws of descent and
distribution, and all Stock Options shall be exercisable during the optionee's
lifetime, only by the optionee; provided, however, that any optionee may
transfer any Non-Qualified Stock Option, whether granted prior to, on or after
September 26, 1996 (including any such options granted to Non-Employee
Directors), to members of his or her immediate family (i.e., his or her
children, grandchildren and spouse) or to one or more trusts for the benefit of
such family members or partnerships in which such family members are the only
partners, if the optionee does not receive any consideration for the transfer.
Any Non-Qualified Stock Options held by any such transferee shall continue to be
subject to the same terms and conditions that were applicable to such
Non-Qualified Stock Options immediately prior to their transfer.

    (f)  TERMINATION BY DEATH.  If an optionee's employment by the company and
any Subsidiary or Parent Corporation terminates  by reason of death, the Stock
Option may thereafter be immediately exercised, to the extent then exercisable
(or on such accelerated basis as the Committee shall determine at or after
grant), by the legal representative of the estate or by the legatee of the
optionee under the will of the optionee, for a period of three years (or such
shorter period as the Committee  shall specify at grant) from the date of such
death or until the expiration of the stated term of the option, whichever
period is  shorter.

    (g)  TERMINATION BY REASON OF DISABILITY.  If an optionee's  employment by
the Company and any Subsidiary or Parent Corporation terminates by reason of
Disability, any Stock Option held by such optionee may thereafter be exercised,
to the extent it was exercisable at the time of termination due to Disability
(or on such accelerated basis as the Committee shall determine at or after
grant), but may not be exercised after three years (or such shorter period as
the Committee shall specify at grant) from the date of such termination of
employment or the expiration of the stated term of the option, whichever period
is the shorter.   In the event of termination of employment by reason of
Disability, if an Incentive Stock Option is exercised after the expiration of
the exercise periods that apply for purposes of Section 422 of the Code, the
option will thereafter be treated as a Non-Qualified Stock Option.

    (h)  TERMINATION BY REASON OF RETIREMENT.  If an optionee's employment by
the Company and any Subsidiary or Parent Corporation terminates by reason of
Retirement, any Stock option held by such optionee may thereafter be exercised
to the extent it was exercisable at the time of such Retirement, but may not


                                          10
<PAGE>

be exercised after three years (or such shorter period as Committee shall 
specify at grant) from the date of such termination of employment or the 
expiration of the stated term of the option, whichever period is the shorter. 
In the event of termination of employment by reason of Retirement, if an 
Incentive Stock option is exercised after the expiration of the exercise 
periods that apply for purposes of Section 422 of the Code, the option will 
thereafter be treated as a Non-Qualified Stock option.

    (i)  OTHER TERMINATION.  Unless otherwise determined by the Committee, if 
an optionee's employment by the Company and any Subsidiary or Parent 
Corporation terminates for any reason other than death, Disability or 
Retirement, the Stock Option shall thereupon terminate, except that the 
option may be exercised to the extent it was exercisable at such termination 
for the lesser of three months or the balance of the option's term if the 
optionee is involuntarily terminated without Cause by the Company and any 
Subsidiary or Parent Corporation.

    (j)  ANNUAL LIMIT ON INCENTIVE STOCK OPTIONS.  The aggregate Fair Market
Value (determined as of the time the Option is granted) of the Common Stock with
respect to which an Incentive Stock Option under this Plan or any other plan of
the Company and any Subsidiary or Parent Corporation is exercisable for the
first time by an optionee during any calendar year shall not exceed $100,000.

    (k)  NON-EMPLOYEE DIRECTORS.  Each Non-Employee Director who (a) is serving
an unexpired term as a director of the Company as of the date of the last
regularly scheduled meeting of the Board during any fiscal year of the Company,
and (b) at the time of such meeting, has served as a director for at least six
(6) months of the twelve (12) month period preceding the date of such meeting,
shall as of the date of such meeting automatically be granted an option to
purchase 7,031 shares of Stock at an option price per share equal to 100% of the
Fair Market Value of a share of Stock on such date.  All such Options shall be
designated as Non-Qualified options and shall be subject to the same terms and
provisions as are then in effect with respect to the granting of Non-Qualified
options to officers and key employees of the Company, except that (i) the term
of each such option shall be equal to ten (10) years, which term shall not
expire upon the termination of service as a director, (ii) the Option shall
become exercisable as to all or any part of the shares subject to the Option
beginning six (6) months after the date the option is granted, and (iii) no
Stock Appreciation Rights may be granted to any Non-Employee Director under this
paragraph (k) or in any other manner under this Plan.  Subject to the foregoing,
all provisions of this Plan not inconsistent with the foregoing shall



                                          11
<PAGE>

apply to Options granted to Non-Employee Directors.  The maximum number of
shares as to which Options may be granted to any Non-Employee Director under
this Plan shall be 140,625 shares.  The maximum aggregate number of shares as to
which Options may be granted to Non-Employee Directors under this Plan shall be
421,875 shares.

    SECTION 6.  STOCK APPRECIATION RIGHTS.

    (a)  GRANT AND EXERCISE.  Except as set forth in paragraph (k) of Section
5, Stock Appreciation Rights may be granted in conjunction with all or part of
any Stock Option granted under the Plan.  In the case of a Non-Qualified Stock
Option, such rights may be granted either at or after the time of the grant of
such Option.  In the case of an Incentive Stock Option, such rights may be
granted only at the time of the grant of the option.

     A Stock Appreciation Right or applicable portion thereof granted with
respect to a given Stock Option shall terminate and no longer be exercisable
upon the termination or exercise of the related Stock option, except that a
Stock Appreciation Right granted with respect to less than the full number of
shares covered by a related stock Option shall not be reduced until the exercise
or termination of the related Stock Option exceeds the number of shares not
covered by the Stock Appreciation Right.

     A Stock Appreciation Right may be exercised by an optionee, in accordance 
with paragraph (b) of this Section 6, by surrendering the applicable portion of
the related Stock option.  Upon such exercise and surrender, the optionee shall
be entitled to receive an amount determined in the manner prescribed in 
paragraph (b) of this Section 6. Stock Options which have been so surrendered, 
in whole or in part, shall no longer be exercisable to the extent the related 
Stock Appreciation Rights have been exercised.

    (b) TERMS AND CONDITIONS.  Stock Appreciation Rights shall be subject to 
such terms and conditions, not inconsistent with the provisions of the Plan, 
as shall be determined from time to time by the Committee, including the 
following:

         (i)  Stock Appreciation Rights shall be exercisable only at such time
    or times and to the extent that the Stock Options to which they relate
    shall be exercisable in accordance with the provisions of Section 5 and
    this Section 6 of the Plan.

         (ii) Upon the exercise of a Stock Appreciation Right, an optionee
    shall be entitled to receive up to, but not more


                                          12
<PAGE>

    than, an amount in cash or shares of Stock equal in value to the excess of
    the Fair Market Value of one share of Stock over the option price per share
    specified in the related option multiplied by the number of shares in
    respect of which the Stock Appreciation Right shall have been exercised,
    with the Committee having the right to determine the form of payment.

         (iii) Stock Appreciation Rights shall be transferable only when and to
    the extent that the underlying Stock Option would be transferable under
    Section 5 of the Plan.

         (iv) Upon the exercise of a Stock Appreciation Right, the Stock
    Option or part thereof to which such Stock Appreciation Right is related
    shall be deemed to have been exercised for the purpose of the limitation
    set forth in Section 3 of the Plan on the number of shares of Stock to be
    issued under the Plan, but only to the extent of the number of shares
    issued or issuable under the Stock Appreciation Right at the time of
    exercise based on the value of the Stock Appreciation Right at such time.

         (v) A Stock Appreciation Right granted in connection with an Incentive
    Stock Option may be exercised only if and when the market price of the
    Stock subject to the Incentive Stock Option exceeds the exercise price of
    such Option.

    SECTION 7.  RESTRICTED STOCK.

    (a)  ADMINISTRATION.  Shares of Restricted Stock may be issued either 
alone or in addition to other awards granted under the Plan.  The Committee 
shall determine the officers and key employees of the Company and 
Subsidiaries to whom, and the time or times at which, grants of Restricted 
Stock will be made, the number of shares to be awarded, the time or times 
within which such awards may be subject to forfeiture, and all other 
conditions of the awards.  The Committee may also condition the grant of 
Restricted Stock upon the attainment of specified performance goals.  The 
provisions of Restricted Stock awards need not be the same with respect to 
each recipient.

    (b) AWARDS AND CERTIFICATES.  The prospective recipient of an award of 
shares of Restricted Stock shall not have any rights with respect to such 
award, unless and until such recipient has executed an agreement evidencing 
the award and has delivered a fully executed copy thereof to the Company, and 
has otherwise complied with the then applicable terms and conditions.

         (i) Each participant shall be issued a stock certificate in respect of
    shares of Restricted Stock awarded


                                          13
<PAGE>

under the Plan. Such certificate shall be registered in the name of the
participant, and shall bear an appropriate legend referring to the terms,
conditions, and restrictions applicable to such award, substantially in the
following form:

         "The transferability of this certificate and the shares of stock
         represented hereby are subject to the terms and conditions (including
         forfeiture) of the Minntech Corporation 1989 Stock Plan and an
         Agreement entered into between the registered owner and Minntech
         Corporation.  Copies of such Plan and Agreement are on file in the
         offices of Minntech Corporation, 14605 28th Avenue North, Minneapolis,
         Minnesota 55447.

         (ii) The Committee shall require that the stock certificates
    evidencing such shares be held in custody by the Company until the
    restrictions thereon shall have lapsed, and that, as a condition of any
    Restricted Stock award, the participant shall have delivered a stock power,
    endorsed in blank, relating to the Stock covered by such award.

    (c)  RESTRICTIONS AND CONDITIONS.  The shares of Restricted Stock awarded 
pursuant to the Plan shall be subject to the following restrictions and 
conditions:

         (i) Subject to the provisions of this Plan and the award agreement,
    during a period set by the Committee commencing with the date of such award
    (the "Restriction Period"), the participant shall not be permitted to sell,
    transfer, pledge or assign shares of Restricted Stock awarded under the
    Plan; provided, however, that the participant may transfer any Restricted
    Stock, whether granted prior to, on or after September 26, 1996, to members
    of his or her immediate family (i.e., his or her children, grandchildren
    and spouse) or to one or more trusts for the benefit of such family members
    or partnerships in which such family members are the only partners, if the
    participant does not receive any consideration for the transfer.  Any
    Restricted Stock held by any such transferee shall continue to be subject
    to the same terms and conditions that were applicable to such Restricted
    Stock immediately prior to its transfer.  In no event shall the Restriction
    Period be less than one (1) year.  Within these limits, the Committee may
    provide for the lapse of such restrictions in installments where deemed
    appropriate.


                                          14
<PAGE>

         (ii)  Except as provided in paragraph (c)(i) of this Section 7, the
    participant shall have, with respect to the shares of Restricted Stock, all
    of the rights of a shareholder of the Company, including the right to vote
    the shares and the right to receive any cash dividends.  The Committee, in
    its sole discretion, may permit or require he  payment of cash dividends to
    be deferred and, if the Committee so determines, reinvested in additional
    shares of Restricted Stock (to the extent shares are available under
    Section 3 and subject to paragraph (f) of Section 12).  Certificates for
    shares of unrestricted Stock shall be delivered to the grantee promptly
    after, and only after, the period of forfeiture shall have expired without
    forfeiture in respect of such shares of Restricted Stock.

         (iii) Subject to the provisions of the award agreement and paragraph
    (c)(iv) of this Section 7, upon termination of employment for any reason 
    during the Restriction Period, all  shares still subject to restriction 
    shall be forfeited by the participant.

         (iv)  In the event of special hardship circumstances of a participant
    whose employment is terminated (other than for Cause), including death,
    Disability or Retirement, or in the event of an unforeseeable emergency of
    a participant still in service, the Committee may, in its sole discretion,
    when it finds that a waiver would be in the best interest of the Company,
    waive in whole or in part any or all remaining restrictions with respect to
    such participant's shares of Restricted Stock.

         (v)  Notwithstanding the foregoing, all restrictions with respect to
    any participant's shares of Restricted Stock that shall not previously have
    been forfeited shall lapse immediately upon the occurrence of a Change in
    Control.

    SECTION 8. DEFERRED STOCK AWARDS.

    (a) ADMINISTRATION.  Deferred Stock may be awarded either alone or in
addition to other awards granted under the Plan.  The Committee shall determine
the officers and key employees of the Company and Subsidiaries to whom and the
time or times at which Deferred Stock shall be awarded, the number of Shares of
Deferred Stock to be awarded to any participant or group of participants, the
duration of the period (the "Deferral Period") during which, and the conditions
under which, receipt of the Stock will be deferred, and the terms and conditions
of the award in addition to those contained in paragraph (b) of this Section 8.
The Committee may also condition the grant of Deferred Stock upon the attainment
of specified performance goals.  The provisions of


                                          15

    (b) TERMS AND CONDITIONS.

         (i) Subject to the provisions of this Plan and the award agreement,
    Deferred Stock awards may not be sold, assigned, transferred, pledged or
    otherwise encumbered during the Deferral Period; provided, however, that
    any participant may transfer any Deferred Stock, whether granted prior to,
    on or after September 26, 1996, to members of his or her immediate family
    (i.e., his or her children, grandchildren and spouse) or to one or more
    trusts for the benefit of such family members or partnerships in which such
    family members are the only partners if the participant does not receive
    any consideration for the transfer.  Any Deferred Stock held by any such
    transferee shall continue to be subject to the same terms and conditions
    that were applicable to such Deferred Stock immediately prior to its
    transfer and the transferee shall be deemed to be the participant for
    purposes of making the election referred to in paragraph (b)(v) of this
    Section 8.  In no event shall the Deferral Period be less than one (1)
    year.  At the expiration of the Deferral Period (or elective Deferral
    Period, where applicable), share certificates shall be delivered to the
    participant, transferee, or their respective legal representative, in a
    number equal to the shares covered by the Deferred Stock award.

         (ii) Amounts equal to any dividends declared during the Deferral
    Period with respect to the number of shares covered by a Deferred Stock
    award will be paid to the participant currently or deferred and deemed to
    be reinvested in additional Deferred Stock or otherwise reinvested, all as
    determined at the time of the award by the Committee, in its sole
    discretion.

         (iii) Subject to the provisions of the award agreement and paragraph
    (b)(iv) of this Section 8, upon termination employment for any reason
    during the Deferral Period for a given award, the Deferred Stock in
    question shall be forfeited by the participant.

         (iv) In the event of special hardship circumstances of a participant 
    whose employment is terminated (other than for Cause) including death, 
    Disability or retirement, or in the event of an unforeseeable emergency of
    a participant still in service, the Committee may, in its sole discretion,
    when it finds that a waiver would be in the best interest of the Company, 
    waive in whole or in part any or all of the


                                          17
<PAGE>

    remaining deferral limitations imposed hereunder with respect to any or all
    of the participant's Deferred Stock.

         (v) A participant may elect to further defer receipt of the award for
    a specified period or until a specified event (the "Elective Deferral
    Period"), subject in each case to the Committee's approval and to such
    terms as are determined by the Committee, all in its sole discretion.
    Subject to any exceptions adopted by the Committee, such election must
    generally be made prior to completion of one half of the Deferral Period
    for a Deferred Stock award (or for an installment of such an award).

         (vi) Each award shall be confirmed by, and subject to the terms of, a
    Deferred Stock agreement executed by the Company and the participant.

         (vii)     Notwithstanding the foregoing, the Deferral Period (or
    Elective Deferred Period, where applicable) with respect to a participant's
    Deferred Stock that shall not previously have been forfeited shall expire
    and share certificates shall be delivered to the participant, or his legal
    representative, in a number equal to the shares covered by the Deferred
    Stock award upon the occurrence of a Change in Control.

    SECTION 9.  TRANSFER, LEAVE OF ABSENCE, ETC.

    For purposes of the Plan, the following events shall not be deemed a
termination of employment:

    (a) a transfer of an employee from the Company to a Parent Corporation or
Subsidiary, or from a Parent Corporation or Subsidiary to the Company, or from
one Subsidiary to another;

    (b) a leave of absence, approved in writing by the Committee, for military
service or sickness, or for any other purpose approved by the Company if the
period of such leave does not exceed ninety (90) days (or such longer period as
the Committee may approve, in its sole discretion); and

    (c) a leave of absence in excess of ninety (90) days, approved in writing
by the Committee, but only if the employee's right to reemployment is guaranteed
either by a statute or by contract, and provided that, in the case of any leave
of absence, the employee returns to work within thirty (30) days after the end
of such leave.

    SECTION 10.  AMENDMENTS AND TERMINATION.


                                          18
<PAGE>

    The Board may amend, alter, or discontinue the Plan, but no amendment,
alteration, or discontinuation shall be made (i) which would impair the rights
of an optionee or participant under a Stock Option, Stock Appreciation Right,
Restricted Stock, Deferred Stock or other Stock-based award theretofore granted,
without the optionee's or participant's consent, or (ii) which without the
approval of the stockholders of the Company would cause the Plan to no longer
comply with Rule 16b-3 under the Securities Exchange Act of 1934, Section 422 of
the Code or any other regulatory requirements.

    The Committee may amend the terms of any award or option theretofore
granted, prospectively or retroactively, but, subject to Section 3 above, no
such amendment shall impair the rights of any holder without his consent.  The
Committee may also substitute new Stock Options for previously granted options,
including previously granted options having higher option prices.

    SECTION 11.  UNFUNDED STATUS OF PLAN.

    The Plan is intended to constitute an "unfunded" plan for incentive and
deferred compensation.  With respect to any payments not yet made to a
participant or optionee by the  Company, nothing contained herein shall give any
such participant or optionee any rights that are greater than those of a general
creditor of the company.  In its sole discretion, the Committee may authorize
the creation of trusts or other arrangements to meet the obligations created
under the Plan to deliver Stock or payments in lieu of or with respect to awards
hereunder provided, however, that the existence of such trusts or other
arrangements is consistent with the unfunded status of the Plan.

    SECTION 12.  GENERAL PROVISIONS.

    (a) The Committee may require each person purchasing shares pursuant to a
Stock option under the Plan to represent to and agree with the Company in
writing that the optionee is acquiring the shares without a view to distribution
thereof.  The certificates for such shares may include any legend which the
Committee deems appropriate to reflect any restrictions on transfer.

    All certificates for shares of Stock delivered under the Plan pursuant to
any Restricted Stock, Deferred Stock or other  Stock-based awards shall be
subject to such stock-transfer orders and other restrictions as the Committee
may deem advisable under the rules, regulations, and other requirements of the
securities and Exchange Commission, any stock exchange upon which the Stock is
then listed, and any applicable Federal or state securities laws, and the
Committee may cause a legend or legends to be put


                                          19
<PAGE>

on any such certificates to make appropriate reference to such restrictions.

    (b) Subject to paragraph (d) below, recipients of Restricted Stock,
Deferred Stock and other Stock-based awards under the Plan (other than Stock
Options) are not required to make any payment or provide consideration other
than the rendering of services.

    (c) Nothing contained in this Plan shall prevent the Board of Directors
from adopting other or additional compensation arrangements, subject to
stockholder approval if such approval is required; and such arrangements may be
either generally applicable or applicable only in specific cases.  The adoption
of the Plan shall not confer upon any employee of the Company or any Subsidiary
any right to continued employment with the Company or a Subsidiary, as the case
may be, nor shall it interfere in any way with the right of the Company or a
Subsidiary to terminate the employment of any of its employees at any time.

    (d) Each participant shall, no later than the date as of which any part of
the value of an award first becomes includible as compensation in the gross
income of the participant for Federal income tax purposes, pay to the Company,
or make arrangements satisfactory to the Committee regarding payment of, any
Federal, state, or local taxes of any kind required by law to be withheld with
respect to the award.  The obligations of the Company under the Plan shall be
conditional on such payment or arrangements and the Company and Subsidiaries
shall, to the extent permitted by law, have the right to deduct any such taxes
from any payment of any kind otherwise due to the participant.  With respect to
any award under the Plan, if the terms of such award so permit, a participant
may elect by written notice to the Company to satisfy part or all of the
withholding tax requirements associated with the award by (i) authorizing the
Company to retain from the number of shares of Stock that would otherwise be
deliverable to the participant, or (ii) delivering to the Company from shares of
Stock already owned by the participant, that number of shares having an
aggregate Fair Market Value equal to part or all of the tax payable by the
participant under this Section 12(d).  Any such election shall be in accordance
with, and subject to, applicable tax and securities laws, regulations and
rulings.

    (e)  At the time of grant, the Committee may provide in connection with any
grant made under this Plan that the shares of Stock received as a result of such
grant shall be subject to a repurchase right in favor of the Company, pursuant
to which the participant shall be required to offer to the Company upon
termination of employment for any reason any shares that the


                                          20
<PAGE>

participant acquired under the Plan, with the price being the then Fair Market
Value of the Stock or, in the case of a termination for Cause, an amount equal
to the cash consideration paid for the Stock, subject to such other terms and
conditions as the Committee may specify at the time of grant.  The Committee
may, at the time of the grant of an award under the Plan, provide the Company
with the right to repurchase, or require the forfeiture of, shares of Stock
acquired pursuant to the Plan by any participant who, at any time within two (2)
years after termination of employment with the Company, directly or indirectly
competes with, or is employed by a competitor of, the Company.

    (f)  The reinvestment of dividends in additional Restricted Stock (or in
Deferred Stock or other types of Plan awards) at the time of any dividend
payment shall only be permissible if the Committee (or the Company's Chief
Financial Officer) certifies in writing that under Section 3 sufficient shares
are available for such reinvestment (taking into account then outstanding Stock
Options and other Plan awards).

    (g)  In the event of (a) the proposed dissolution or liquidation of the
Company, (b) a proposed sale of substantially all of the assets of the Company
or (c) a proposed merger or consolidation of the Company with or into any other
entity, regardless of whether the Company is the surviving corporation, or a
proposed statutory share exchange with any other entity (the actual effective
date of the dissolution, liquidation, sale, merger, consolidation or exchange
being herein called an "Event"), the Committee may, but shall not be obligated
to, either (i) if the Event is a merger, consolidation or statutory share
exchange, make appropriate provision for the protection of outstanding Stock
Options, Stock Appreciation Rights, Restricted Stock and Deferred Stock awards
granted under this Plan by the substitution, in lieu of such Stock Options,
Stock Appreciation Rights, Restricted Stock or Deferred Stock awards, of options
to purchase, or stock appreciation rights with respect to, appropriate voting
common stock (or of restricted voting common stock or, with respect to Deferred
Stock Awards, voting common stock), as the case may be (the "Survivor's Stock")
of the corporation surviving any such merger or consolidation or, if
appropriate, the parent corporation of the Company or such surviving
corporation, or, alternatively with respect to Stock Options or Stock
Appreciation Rights, by the delivery of a number of shares of the Survivor's
Stock which has a Fair Market Value as of the effective date of such merger,
consolidation or statutory share exchange equal to the product of (x) the excess
of (A) the Event Proceeds per Share (as hereinafter defined) covered by the
Stock Options or Stock Appreciation Rights as of such effective date over
(B) the exercise price per share of the


                                          21
<PAGE>

shares of Stock subject to such Stock Options or used to measure the value of
such Stock Appreciation Rights, times (y) the number of shares covered by such
Stock Options or Stock Appreciation Rights, as the case may be, or (ii) declare,
at least twenty days prior to the Event, and provide written notice to each
optionee of the declaration, that each outstanding Stock Option and Stock
Appreciation Right, whether or not then exercisable, shall be canceled at the
time of, or immediately prior to the occurrence of, the Event (unless it shall
have been exercised prior to the occurrence of the Event).  In connection with
any declaration pursuant to clause (ii) of the preceding sentence, the Committee
may, but shall not be obligated to, cause payment to be made, within twenty days
after the Event, in exchange for each canceled Stock Option and Stock
Appreciation Right, of cash equal to the amount (if any), for each share of
Stock covered by the canceled option or used to measure the value of a Stock
Appreciation Right, by which the Event Proceeds per share of Stock (as
hereinafter defined) exceeds the exercise price per Share covered by such Stock
Option or used to measure the value of a Stock Appreciation Right.  At the time
of any declaration pursuant to clause (ii) of the first sentence of this
paragraph (g), each Stock Option and Stock Appreciation Right that has not
previously expired  or have been terminated or canceled pursuant to this Plan
shall immediately become exercisable in full and each optionee or holder of a
stock appreciation right shall have the right, during the period preceding the
time of cancellation of the Stock Option or Stock Appreciation Right, to
exercise his or her Stock Option or Stock Appreciation Right as to all or any
part of the Shares covered thereby or used to measure the value thereof.  In the
event of a declaration pursuant to clause (ii) of the first sentence of this
paragraph (g), each outstanding Stock Option and Stock Appreciation Right
granted pursuant to this Plan that shall not have been exercised prior to the
Event shall be canceled at the time of, or immediately prior to, the Event, as
provided in the declaration, subject to the payment obligations of the Company,
if any, provided in this paragraph (g).  Notwithstanding the foregoing, no
person holding a Stock Option or Stock Appreciation Right shall be entitled to
the payment provided in this paragraph (g) if a Stock Option or Stock
Appreciation Right shall have expired pursuant to this Plan.  For purposes of
this paragraph (g), "Event Proceeds per Share" shall mean the cash plus the fair
market value, as determined in good faith by the Committee, of the non-cash
consideration to be received per share of Stock by the shareholders of the
Company upon the occurrence of the Event.  Nothing stated in this paragraph (g)
shall impair the rights of an optionee (unless the consent of the optionee shall
have been obtained) under a Stock Option granted to such optionee on or prior to
September 26, 1996, the date of adoption of the Amendment to this Plan to add
paragraph (g).

    SECTION 13.  EFFECTIVE DATE OF PLAN.

    The Plan shall be effective on the date it is approved by a vote of the
holders of a majority of the Stock present and entitled to vote at a meeting of
the Company's shareholders.

interests of Company and its shareholders; and

         WHEREAS, the Executive is expected to continue to make a significant
contribution to the profitability, growth and financial strength of Company; and

         WHEREAS, Company, as a publicly held corporation, recognizes that the
possibility of a Change in Control may exist and that such possibility, and the
uncertainty and questions which it may raise among management, may result in the
departure or distraction of the Executive in the performance of the Executive's
duties to the detriment of Company and its shareholders; and

         WHEREAS, the Executive is willing to continue to be an employee of
Company upon the understanding that Company will provide income security if the
Executive's employment is terminated under certain terms and conditions; and

         WHEREAS, it is in the best interests of Company and its shareholders
to reinforce and encourage the continued attention and dedication of management
personnel, including the Executive, to their assigned duties without distraction
and to increase the likelihood of the continued availability to Company of the
Executive in the event of a Change in Control.

         THEREFORE, in consideration of the foregoing and other respective
covenants and agreements of the parties herein contained, the parties hereto
agree as follows:

         1.   TERM OF AGREEMENT.  This Agreement shall commence on the date
hereof and shall continue in effect until such time as Company notifies the
Executive or the Executive notifies Company of termination of this Agreement;
provided, however, that in no event may this Agreement be terminated prior to
two years from the date hereof, and notice of termination on the second or any
subsequent anniversary date hereof must be given by Company in writing mailed to

extension hereof), this Agreement shall continue in effect for a period of 36
months from the date of the occurrence of a Change in Control.  Except as
provided in Section 2(b) or Section 3(e) of this Agreement, nothing stated
herein shall limit the right of the Executive or Company to terminate the
employment of the Executive with Company at any time prior to the expiration of
the term of this Agreement, with or without Cause (as defined in Section 3(b) of
this Agreement) and for any reason whatsoever, subject to the right of the
Executive to receive any payment and other benefits that may be due pursuant to
the terms and conditions of Section 4 of this Agreement.

         2.   CHANGE IN CONTROL.  No amounts shall be payable hereunder unless
a Change in Control, as set forth below, shall occur during the term of this

              successor rule under the Exchange Act), directly or indirectly,

              voting power of Company's then outstanding securities entitled to
              vote generally in the election of directors ("Voting
              Securities"), provided, however, that the following shall not
              constitute a Change in Control pursuant to this Section 2(a)(i):

                        (A)  any acquisition or beneficial ownership by Company
                   or a subsidiary of Company;

                        (B)  any acquisition or beneficial ownership by any

                   directly or indirectly, by all or substantially all of the
                   persons who beneficially owned Voting Securities and common
                   stock of Company immediately prior to such acquisition in
                   substantially

                   Securities and common stock, as the case may be, immediately
                   prior to such acquisition;

                   (ii) A majority of the members of the Board of Directors of
              Company shall not be Continuing Directors.  For purposes of this
              subsection 2(a)(ii), "Continuing Directors" shall mean:  (A)

                   (iii) Approval by the shareholders of Company of a
              reorganization, merger or consolidation of Company (other than a

              persons who were the beneficial owners, respectively, of Voting

              combined voting power of the then outstanding voting securities
              entitled to vote generally in the election of directors and the
              then outstanding shares of common stock, as the case may be, of
              the corporation resulting from such reorganization, merger,
              consolidation or exchange in substantially the same proportions
              as their ownership, immediately prior to such reorganization,
              merger, consolidation or exchange, of the Voting Securities and
              common stock of Company, as the case may be;

                   (iv) Approval by the shareholders of Company of (x) a
              complete liquidation or dissolution of Company or (y) the sale or

              Company (in one or a series of transactions), other than to a
              corporation with respect to which, immediately following such
              sale or other disposition, more than 70% of, respectively, the
              combined voting power of the then outstanding voting securities
              of such corporation entitled to vote generally in the election of
              directors and the then outstanding shares of common stock of such
              corporation is then beneficially owned, directly or indirectly,
              by all or substantially all of the persons who were the


                                          3

<PAGE>

              beneficial owners, respectively, of the Voting Securities and
              common stock of Company immediately prior to such sale or other
              disposition in substantially the same proportions as their
              ownership, immediately prior to such sale or other disposition,
              of the Voting Securities and common stock of Company, as the case
              may be; or

                   (v)  Company enters into a letter of intent, an agreement in
              principle or a definitive agreement relating to a Change in
              Control described in Section 2(a)(i), 2(a)(ii), 2(a)(iii) or
              2(a)(iv) above that ultimately results in such a Change in
              Control or a tender or exchange offer or proxy contest is
              commenced which ultimately results in a Change in Control
              described in Section 2(a)(i) or 2(a)(ii) hereof.

         Notwithstanding the above, a Change in Control shall not be deemed to
         occur with respect to the Executive if (x) the acquisition or
         beneficial ownership of the 30% or greater interest referred to in
         Section 2(a)(i) is by the Executive or by a group, acting in concert,
         that includes the Executive or (y) if a majority of the then combined
         voting power of the then outstanding voting securities (or voting
         equity interests) of the surviving corporation or of any corporation
         (or other entity) acquiring all or substantially all of the assets of
         Company shall, immediately after a reorganization, merger,
         consolidation, statutory share exchange or disposition of assets
         referred to in Section 2(a)(iii) or 2(a)(iv), be beneficially owned,
         directly or indirectly, by the Executive or by a group, acting in
         concert, that includes the Executive.

              (b)  The Executive agrees that, subject to the terms and
         conditions of this Agreement, in the event of a Change in Control of
         Company described in Section 2(a)(i), 2(a)(ii), 2(a)(iii) or 2(a)(iv),
         occurring after the date hereof, the Executive, if employed by Company
         immediately prior to such a Change in Control, will not voluntarily
         terminate employment with Company except for Good Reason for a period
         of 90 days after the occurrence of such a Change in Control of
         Company.

              (c)  For purposes of this Agreement, a "subsidiary" of Company
         shall mean any entity of which securities or other ownership interests
         having general voting power to elect a majority of the board of
         directors or other persons performing similar functions are at the
         time directly or indirectly owned by Company.

         3.   TERMINATION FOLLOWING CHANGE IN CONTROL.  If a Change in Control
shall occur during the term of this Agreement, the Executive shall be entitled
to the payments and other benefits provided in subsection 4(d) in the event of
the termination of the Executive's employment with Company unless the
Executive's termination is (A) because of the


                                          4

<PAGE>

Executive's death, (B) by Company for Cause or Disability, or (C) by the
Executive other than for Good Reason.

              (a)  DISABILITY.  If, as a result of incapacity due to physical
         or mental illness, the Executive shall have been absent from the
         full-time performance of the Executive's duties with Company for six
         consecutive months, and within 30 days after written Notice of
         Termination is given, the Executive shall not have returned to the
         full-time performance of the Executive's duties, Company may terminate
         the Executive's employment for "Disability".  Any question as to the
         existence of the Executive's Disability upon which the Executive and
         Company cannot agree shall be determined by a qualified independent
         physician selected by the Executive (or, if the Executive is unable to
         make such selection, it shall be made by any adult member of the
         Executive's immediate family), and approved by Company.  The
         determination of such physician made in writing to Company and to the
         Executive shall be final and conclusive for all purposes of this
         Agreement.

              (b)  CAUSE.  Termination of the Executive's employment for
         "Cause" shall mean termination upon the conviction of the Executive by
         a court of competent jurisdiction for felony criminal conduct.

              (c)  GOOD REASON.  Termination by the Executive for "Good Reason"
         shall mean termination by the Executive if, without the Executive's
         express written consent, any of the following shall occur:

                   (i)  the assignment to the Executive of any duties
              inconsistent with the Executive's status or position with
              Company, or a substantial alteration in the nature or status of
              the Executive's responsibilities from those in effect immediately
              prior to the Change in Control;

                   (ii) a reduction by Company in the Executive's annual base
              salary in effect immediately prior to a Change in Control;

                   (iii) the relocation of Company's principal executive
              offices to a location more than fifty miles from Plymouth,
              Minnesota or Company requiring the Executive to be based anywhere
              other than Company's principal executive office (or if the
              Executive is based at a location other than Company's principal
              executive office immediately prior to the first Change in
              Control, anywhere other than such location) except for required
              travel on Company's business to an extent substantially
              consistent with the Executive's prior business travel
              obligations;


                                          5

<PAGE>

                   (iv) the failure by Company to continue to provide the
              Executive with benefits at least as favorable to those enjoyed by
              the Executive under any of Company's pension, life insurance,
              medical, health and accident, disability, deferred compensation,
              incentive awards, employee stock options, or savings plans in
              which the Executive was participating at the time of the Change
              in Control, the taking of any action by Company which would
              directly or indirectly materially reduce any of such benefits or
              deprive the Executive of any material fringe benefit enjoyed at
              the time of the Change in Control, or the failure by Company to
              provide the Executive with the number of paid vacation days to
              which the Executive is entitled at the time of the Change in
              Control, provided, however, that Company may amend any such plan
              or programs as long as such amendments do not reduce any benefits
              to which the Executive would be entitled upon termination;

                   (v)  a termination pursuant to Section 3(d) of this
              Agreement;

                   (vi) the failure of Company to obtain a satisfactory
              agreement from any successor to assume and agree to perform this
              Agreement, as contemplated in Section 6; or

                   (vii) any purported termination of the Executive's
              employment which is not made pursuant to a Notice of Termination
              satisfying the requirements of subsection (e) below; for purposes
              of this Agreement, no such purported termination shall be
              effective.

              (d)  VOLUNTARY TERMINATION DEEMED GOOD REASON.  Notwithstanding
         anything herein to the contrary, during the period commencing on the
         91st day following a Change in Control under Section 2(a)(i),
         2(a)(ii), 2(a)(iii) or 2(a)(iv) of this Agreement and ending on the
         180th day following such a Change in Control, the Executive may
         voluntarily terminate his or her employment for any reason, and such
         termination shall be deemed "Good Reason" for all purposes of this
         Agreement.  In the event of such voluntary termination pursuant to
         this subsection 3(d)), the multiple applied to the Severance Payment
         (as defined in Section 4(d)), if any, payable to the Executive
         pursuant to subsection 4(d)(ii) below shall be reduced by 50%.

              (e)  NOTICE OF TERMINATION.  Any purported termination of the
         Executive's employment by Company or by the Executive shall be
         communicated by written Notice of Termination to the other party
         hereto in accordance with Section 7.  For purposes of this Agreement,
         a "Notice of Termination" shall mean a notice which shall indicate the
         specific termination provision in this Agreement relied upon and shall
         set forth the facts and


                                          6

<PAGE>

         circumstances claimed to provide a basis for termination of the
         Executive's employment.

              (f)  DATE OF TERMINATION.  For purposes of this Agreement, "Date
         of Termination" shall mean:

                   (i)  if the Executive's employment is terminated for
              Disability, 30 days after Notice of Termination is given
              (provided that the Executive shall not have returned to the
              full-time performance of the Executive's duties during such 30
              day period); and

                   (ii) if the Executive's employment is terminated pursuant to
              subsections (b), (c) or (d) above or for any other reason (other
              than Disability), the date specified in the Notice of Termination
              (which, in the case of a termination pursuant to subsection (b)
              above, shall not be less than 10 days, and, in the case of a
              termination pursuant to subsection (c) or (d) above, shall not be
              less than 10 nor more than 30 days, respectively, from the date
              such Notice of Termination is given).

              (g)  DISPUTE OF TERMINATION.  If, within 10 days after any Notice
         of Termination is given, the party receiving such Notice of
         Termination notifies the other party that a dispute exists concerning
         the termination, the Date of Termination shall be the date on which
         the dispute is finally determined, either by mutual written agreement
         of the parties, or by a final judgment, order or decree of a court of
         competent jurisdiction (which is not appealable or the time for appeal
         therefrom having expired and no appeal having been perfected);
         provided, that the Date of Termination shall be extended by a notice
         of dispute only if such notice is given in good faith and the party
         giving such notice pursues the resolution of such dispute with
         reasonable diligence.  Notwithstanding the pendency of any such
         dispute, Company shall continue to pay the Executive full compensation
         in effect when the notice giving rise to the dispute was given
         (including, but not limited to, base salary) and continue the
         Executive as a participant in all compensation, benefit and insurance
         plans in which the Executive was participating when the notice giving
         rise to the dispute was given, until the dispute is finally resolved
         in accordance with this subsection.  Amounts paid under this
         subsection are in addition to all other amounts due under this
         Agreement and, except as provided in Section 4(d)(v), shall not be
         offset against or reduce any other amounts under this Agreement.

         4.   COMPENSATION UPON TERMINATION OR DURING DISABILITY.  Upon
termination of the Executive's employment (or, with respect to Section 4(a),
during a period of Disability) following a Change in Control, as defined in
Section 2(a), of Company or if


                                          7

<PAGE>

there shall be a termination by Company of the Executive's employment prior to a
Change in Control, or the Executive shall terminate employment with Company for
Good Reason prior to a Change in Control (for which purpose the references in
Section 3(c) to changes from circumstances existing immediately prior to or at
the time of a Change in Control that constitute Good Reason for termination
shall instead be deemed to be references to circumstances existing immediately
prior to or at the time that the Change in Control is first anticipated), and
the Executive reasonably demonstrates that such termination by Company or event
constituting Good Reason for termination by the Executive (x) was requested by a
third party that had previously taken other steps reasonably calculated to
result in a Change in Control described in Section 2(a)(i), 2(a)(ii), 2(a)(iii)
or 2(a)(iv) and ultimately resulting in such a Change in Control following
termination of the Executive's employment or (y) otherwise arose in connection
with or in anticipation of a Change in Control described in Section 2(a)(i),
2(a)(ii), 2(a)(iii) or 2(a)(iv) that ultimately occurs following termination of
the Executive's employment, the Executive shall be entitled to the following
benefits:

              (a)  Except as provided in Section 4(b), during any period that
         the Executive fails to perform full-time duties with Company as a
         result of Disability, Company shall pay the Executive the base salary
         of the Executive at the rate in effect at the commencement of any such
         period, until such time as the Executive is determined to be eligible
         for long term disability benefits in accordance with Company's
         insurance programs then in effect.

              (b)  If the Executive's employment shall be terminated by Company
         for Cause or Disability or by the Executive, following a Change in
         Control, other than for Good Reason, Company shall pay to the
         Executive his or her full base salary through the Date of Termination
         at the rate in effect at the time Notice of Termination is given and
         Company shall have no further obligation to the Executive under this
         Agreement.

              (c)  If the Executive's employment shall be terminated by Company
         for Cause or Disability, or is terminated by reason of death, Company
         shall immediately cause to be commenced payment to the Executive (or
         the Executive's designated beneficiaries or estate, if no beneficiary
         is designated) of any and all benefits to which the Executive is
         entitled, if any, under Company's insurance programs then in effect.

              (d)  Except for termination of the Executive's employment with
         Company by reason of death, if the Executive's employment with Company
         shall be terminated (A) by Company other than for Cause or Disability
         or (B) by the Executive for Good Reason, then the Executive shall be
         entitled to the benefits provided below:


                                          8

<PAGE>

                   (i)  Company shall pay the Executive the Executive's full
              base salary through the Date of Termination at the rate in effect
              at the time the Notice of Termination is given.

                   (ii) In lieu of any further salary payments for periods
              subsequent to the Date of Termination, Company shall pay as a
              severance payment (the "Severance Payment")  an amount equal to
              (A) three (3) times (subject to reduction pursuant to Section
              3(d) in the event of a termination of employment by the Executive
              pursuant to Section 3(d)) the average of the annual compensation
              which was paid to the Executive by Company (or any corporation
              affiliated with Company within the meaning of Section 1504 of the
              Internal Revenue Code of 1986, as amended (the "Code")) and
              includible in the Executive's gross income for federal income tax
              purposes for the shorter of the period consisting of (1) the five
              most recently completed taxable years of the Executive ending
              before the earlier of the first Change in Control (for which
              purpose the first Change in Control shall not be deemed to be a
              Change in Control pursuant to Section 2(a)(v) unless the
              Executive's termination of employment with Company occurs prior
              to the first Change in Control pursuant to Section 2(a)(i),
              2(a)(ii), 2(a)(iii) or 2(a)(iv)) or (2) that portion of such
              five-year period during which the Executive was employed by
              Company, less (B) $1.00.  Such average shall be determined in
              accordance with temporary or final regulations promulgated under
              Section 280G(d) of the Code or any successor provision thereto.
              The Severance Payment shall be made in full within 60 days after
              termination of employment.  Such Severance Payment shall be
              reduced by any severance pay that the Executive receives from
              Company, any subsidiary of Company or any successor thereof under
              any other policy or agreement of Company in the event of
              involuntary termination of the Executive's employment.

                   (iii) For a 36 month period after the Date of
              Termination,  Company shall arrange to provide the Executive with
              life, disability, accident and health insurance benefits
              substantially similar to those which the Executive is receiving
              or entitled to receive immediately prior to the Notice of
              Termination.  Benefits otherwise receivable by the Executive
              pursuant to this paragraph (iii) shall be reduced to the extent
              comparable benefits are actually received by the Executive from
              another employer or other third party during such 36 month
              period, and any such benefits actually received by the Executive
              shall be reported to Company.

                   (iv) Company shall also pay to the Executive all legal fees
              and expenses incurred by the Executive as a result of such
              termination (including all such fees and expenses, if any,
              incurred in contesting or disputing any such termination or in
              seeking to obtain or enforce any right or benefit provided by
              this Agreement).

                   (v)  Notwithstanding any provision to the contrary contained
              herein except the last sentence of this Section 4(d)(v), if the
              lump sum cash payment due and the other benefits to which the
              Executive shall become entitled under this Section 4 hereof,
              either alone or together with other payments in the nature of
              compensation to the Executive which are contingent on a change in
              the ownership or effective control of Company or in the ownership
              of a substantial portion of the assets of Company or otherwise,
              would constitute a "parachute payment" as defined in Section 280G
              of the Code or any successor provision thereto, such lump sum
              payment and/or such other benefits and payments shall be reduced
              (but not below zero) to the largest aggregate amount as will
              result in no portion thereof being subject to the excise tax
              imposed under Section 4999 of the Code (or any successor
              provision thereto) or being non-deductible to Company for federal
              income tax purposes pursuant to Section 280G of the Code (or any
              successor provision thereto).  The Executive in good faith shall
              determine the amount of any reduction to be made pursuant to this
              Section 4(d)(v) and shall select from among the foregoing
              benefits and payments those which shall be reduced.  No
              modification of, or successor provision to, Section 280G or
              Section 4999 subsequent to the date of this Agreement shall,
              however, reduce the benefits to which the Executive would be
              entitled under this Agreement in the absence of this Section
              4(d)(v) to a greater extent than they would have been reduced if
              Section 280G and Section 4999 had not been modified or superseded
              subsequent to the date of this Agreement, notwithstanding
              anything to the contrary provided in the first sentence of this
              Section 4(d)(v).

              (e)  The Executive shall not be required to mitigate the amount
         of any payment provided for in this Section 4 by seeking other
         employment or otherwise, nor shall the amount of any payment or
         benefit provided for in this Section 4 be reduced by any compensation
         earned by the Executive as the result of employment by another
         employer or by retirement benefits after the Date of Termination, or
         otherwise except as specifically provided in this Section 4.

              (f)  In addition to all other amounts payable to the Executive
         under this Section 4, the Executive shall be entitled to receive all
         benefits payable to the Executive under any other plan or agreement
         relating to retirement benefits except as specifically provided in
         this Section 4.

              (g)  If Company fails to make any payment at the times and in the
         amounts specified herein, or with respect to any fringe benefits,
         fails to provide such benefit as specified herein, within 10 days from
         the date of written notice from the Executive to Company of such
         failure, Company shall be deemed to have waived any right to enforce
         any restriction on employment or non-competition provision contained
         in any agreement between Company and the Executive then in existence
         which limits the ability of the Executive to accept other employment
         and, thereafter, the Executive may work or consult for any person or
         business organization which is engaged in the design, development,
         assembly, manufacture, marketing or sale of any product which competes
         with any product of Company, or for any person or business
         organization which is in competition with Company, without liability
         to Company for such acts.  A waiver of such restrictive covenant or
         non-competition provision shall not in any way restrict or limit the
         Executive's right to enforce the provisions of this Agreement,
         including any legal or equitable action to enforce any and all
         payments, rights or benefits under this Agreement, it being the
         intention of this subsection that such waiver shall be in addition to,
         not in substitution of, any other rights to which the Executive is
         entitled hereunder.  Once waived, any such restrictive covenant or
         non-competition provision shall not thereafter be enforceable even
         though the Executive may later receive the payment, right or benefit
         which was the basis of the waiver of such restrictive covenant or
         non-competition provision.

         5.   FUNDING OF PAYMENTS.  In order to assure the performance of
Company or its successor of its obligations under this Agreement, Company may
deposit in trust an amount equal to the maximum payment that will be due the
Executive under the terms hereof.  Under a written trust instrument, the Trustee
shall be instructed to pay to the Executive (or the Executive's legal
representative, as the case may be) the amount to which the Executive shall be
entitled under the terms hereof, and the balance, if any, of the trust not so
paid or reserved for payment shall be repaid to Company.  If Company deposits
funds in trust, payment shall be made no later than the occurrence of the first
Change in Control described in Section 2(a)(i), 2(a)(ii), 2(a)(iii) or 2(a)(iv).
Company shall give notice of such a Change in Control to any such trustee upon
any occurrence as defined herein.  If and to the extent that the Executive
becomes a beneficiary of any such funds deposited in trust, Company shall give
prompt notice to the Executive, which shall include a copy of the trust
instrument and amendments from time to time.  The rights of the Executive under
such trust instrument shall be enforceable against Company and any trustees
named therein, as though the provisions of said trust were incorporated into
this Agreement.  If and to the extent there are not amounts in trust sufficient
to pay the Executive under this Agreement, Company shall remain liable for any
and all payments due to the Executive.  In accordance with the terms of such
trust, at all times during the term of this Agreement, the Executive shall have
no rights, other than as an


                                          11

<PAGE>

unsecured general creditor of Company, to any amounts held in trust and all
trust assets shall be general assets of Company and subject to the claims of
creditors of Company.

         6.   SUCCESSORS; BINDING AGREEMENT.

              (a)  Company will require any successor (whether direct or
         indirect, by purchase, merger, consolidation or otherwise) to all or
         substantially all of the business and/or assets of Company to
         expressly assume and agree to perform this Agreement in the same
         manner and to the same extent that Company would be required to
         perform it if no such succession had taken place.  Failure of Company
         to obtain such assumption and agreement prior to the effectiveness of
         any such succession shall be a breach of this Agreement and shall
         entitle the Executive to compensation from Company in the same amount
         and on the same terms as he would be entitled hereunder if he
         terminated his employment for Good Reason following a Change in
         Control, except that for purposes of implementing the foregoing, the
         date on which any such succession becomes effective shall be deemed
         the Date of Termination.

              (b)  This Agreement shall inure to the benefit of and be
         enforceable by the Executive's personal or legal representatives,
         successors, heirs, and designated beneficiaries.  If the Executive
         should die while any amount would still be payable to the Executive
         hereunder if the Executive had continued to live, all such amounts,
         unless otherwise provided herein, shall be paid in accordance with the
         terms of this Agreement to the Executive's designated beneficiaries,
         or, if there is no such designated beneficiary, to the Executive's
         estate.

         7.   NOTICE.  For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered or certified mail, return receipt requested, postage pre-paid,
addressed to the last known residence address of the Executive or in the case of
Company, to its principal executive office to the attention of each of the then
directors of Company with a copy to its Secretary, or to such other address as
either party may have furnished to the other in writing in accordance herewith,
except that notice of change of address shall be effective only upon receipt.

         8.   MISCELLANEOUS.

              (a)  No provision of this Agreement may be modified, waived or
         discharged unless such waiver, modification or discharge is agreed to
         in writing and signed by the parties.  No waiver by either party
         hereto at any time of any breach by the other party to this Agreement
         of, or compliance with, any condition or provision of this Agreement
         to be performed by such other party


                                          12

         shall be deemed a waiver of similar or dissimilar provisions or
         conditions at the same or at any prior to similar time.  No legally
         binding or enforceable agreements or representations, oral or
         otherwise, express or implied, with respect to the subject matter
         hereof that remain in effect have been made by either party which are
         not expressly set forth in this Agreement.  The validity,
         interpretation, construction and performance of this Agreement shall
         be governed by the laws of the State of Minnesota.

              (b)  This Agreement supersedes in all respects the Employment
         Agreement between the Executive and Company dated April 22, 1986 (the
         "Superseded Change in Control Agreement"), which Superseded Change in
         Control Agreement is hereby terminated and shall be of no further
         force or effect.

         9.   VALIDITY.  The invalidity or unenforceability or any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

              i.   All Inventions related to Minntech Products (defined in
                   subparagraph 8.a.iii below) made by Cosentino during the

                   the Company will not be required to designate Cosentino as

                        including, but not limited to, signing all documents,
                        doing all things, and supplying all information that
                        the Company may deem necessary or desirable to:  (1)
                        transfer or record the transfer of Cosentino's entire
                        right, title, and interest in Inventions to the
                        Company, and (2) enable the Company to obtain and
                        maintain patent, copyright, or trademark protection for

                   Inventions conceived or made by Cosentino during the
                   Consultancy Period.  For purposes of this Agreement, any
                   Invention relating to the existing or reasonable foreseeable
                   Minntech Products for which Cosentino files a patent
                   application within one year after the end of the Consultancy
                   Period will be presumed to be an Invention conceived by
                   Cosentino during the Consultancy Period, subject to proof to
                   the contrary that such Invention was

                   Period.

              v.   For purposes of this subparagraph 3.h., "Invention" means
                   any invention, discovery, improvement, concept, or idea,
                   whether or not patentable (including those which may be
                   subject to copyright protection), including, but not limited
                   to, computer software and hardware technology, machines,
                   devices, processes, methods, techniques, and formulae which
                   are generated, conceived, or reduced to practice by
                   Cosentino along or in conjunction with others, during or
                   after working hours, while serving as a consultant to the
                   Company.

              vi.  Cosentino is hereby notified that this Agreement does not
                   apply to any invention for which no equipment, supplies,
                   facility, trade secret information, or Confidential 
                   Information (defined in subparagraph 8.a.iv. below) of the
                   Company was used and which was developed entirely on
                   Cosentino's own time, and (1) which does not relate (a)
                   directly to the business of the Company or (b) to the
                   Company's actual or demonstrably anticipated research

                        for Cause, or

                   C.   expiration of the term of the consultancy,then the
                   Company will pay Cosentino's Consultant's Fee through the

                   then the Company will continue to pay Cosentino's Consulting
                   Fee through March 31, 2000, and Cosentino will continue to
                   accrue rights to receive Supplemental Retirement Benefits

              iii. Termination of the consultancy by either party for any

                        Cosentino to the Company in his capacity as a Director
                        of the Company; or

                   G.   commission of a crime by Cosentino or other public
                        misconduct by him detrimental to the reputation of the
                        Company.

              v.   "Disability" means the inability of Cosentino to perform his
                   duties as a consultant by reason of illness or other
                   physical or mental impairment or condition, if such
                   inability continues for an uninterrupted period of 90 days
                   or more.  A period of inability will be "uninterrupted"
                   unless and until Cosentino is able to work as a consultant
                   for a continuous period of at least 30 days.

         k.   NOTICE.  If Cosentino decides to resign as a consultant to the
Company for any reason, then he will give the Company written notice of his
resignation six months in advance of the effective date of his resignation.  If
the Company decides to terminate Cosentino's consultancy for any reason other
than for Cause, then the Company will give Cosentino written notice of such
termination six months in advance of the effective date of the termination. 
Neither party will be required to give notice to the other party of the party's
decision not to seek an extension of the term of this Agreement beyond the term
specified in subparagraph 3.a. above.

         4.   PAYMENTS.  In consideration of Cosentino's past services to the
Company as an 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 subparagraphs 4.a. through 4.f. below to
Cosentino or for his benefit, but only if:  (i) Cosentino has not rescinded this
Agreement or the Cosentino Release within the applicable rescission period; and
(ii) the Company has received written confirmation from Cosentino, 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 Cosentino has not
rescinded and will not rescind this Agreement or the Cosentino Release.  Payment
of any amount set forth below will not modify or terminate the parties'
obligations to each other as established by this Agreement.  The payments set
forth below will be sent by first-class mail to Cosentino's last known residence
address, unless he advises the Company in writing that he wants the payments
sent to a different address.

              a.   SEVERANCE PAY.  The Company will pay Cosentino (or his
designated beneficiary or estate, as the case may be) Severance Pay of

approximately equal bi-weekly installments during the period between April 1,
1997 and March 31, 2000; provided, however, that no installment will be paid to

prior to the Payment Date will not be forfeited but will be paid to  Cosentino
on the Payment Date.

              b.   CONSULTANT'S FEE.  The Company will pay Cosentino a
Consultant's Fee of $2,777.78 per month on or about the last business day of

              c.   SUPPLEMENTAL RETIREMENT BENEFIT.  The Company will pay
Cosentino (or his designated beneficiary or estate, as the case may be) a
Supplemental Retirement Benefit.  The Company will pay the Supplemental
Retirement Benefit in monthly installments of $31,250.00 on or about the last
business day of each month commencing in the month during which Cosentino turns
age 65 (or would have turned age 65 if he were then still living) over a number
of months equal to the total number of full months of the Consultancy Period.

              d.   BENEFICIARY DESIGNATION.  Any designation of a beneficiary
for purposes of subparagraphs 4.a. and 4.c. above must be made by Cosentino in
writing and must be furnished to the Company's Vice President and General
Counsel.  If no effective beneficiary designation is on file with the Company at
the time of Cosentino's death, then any remaining Severance Pay and the
Supplemental Retirement Benefit will be paid to his estate.

              e.   HEALTH INSURANCE.  During the Consultancy Period the Company
will either make group health insurance available to Cosentino on the same basis


                                         -14-

and on the same terms that such insurance is made available to senior managers
of the Company or will provide him with an individual health insurance policy,
provided that Cosentino is able to comply with all requirements respecting
insurability.  So long as Cosentino is covered under the Company's group health
insurance program, the Company will pay the same portion of the premium as the
Company pays for its senior managers for such coverage, and any portion of the
premium for such coverage payable by Cosentino will be paid by him at least
monthly on or before the last day of each month during which he is subject to
such coverage.  So long as Cosentino is covered by an individual health
insurance policy provided by the Company, he will pay the Company at least
monthly on or before the last day of each month during which he has such
coverage the same amount that he last paid to the Company for his portion of the
premium for coverage under the Company's group health insurance program, and the
Company will pay the balance of the premium for such individual coverage up to a
maximum of $340.56 per month.  The Company will have no obligation to pay any
portion of any premiums for either group health insurance coverage or for an
individual health insurance policy provided by the Company after the month in
which the Consultancy Period ends.

              f.   AUTO LEASE.  The Company will continue to make the monthly
lease payments on the 1995 leased Lexus LS-400 automobile provided to Cosentino
by the Company until the end of the lease or the end of the Consultancy Period,
whichever is earlier.  If the Company makes such lease payments until the end of
the lease, then Cosentino will

have the option to purchase the automobile from the leasing company for the
residual value of approximately $26,810.00.  If the Consultancy Period ends
before all of the monthly lease payments are made by the Company, then the
automobile will be returned to the Company by Cosentino no later than the last
business day of the month in which the Consultancy Period ends.

              g.   ATTORNEYS' FEES.  The Company will pay to the law firm of
Leonard, Street & Deinard PA ("Leonard-Street") an amount not to exceed
$25,000.00 for the attorneys' fees and costs that Cosentino incurs in connection
with his separation from the Company and the establishment of his consultancy
with the Company.  Leonard-Street will submit its detailed invoice for fees and
costs, showing each date on which the legal services were rendered, the hours
spent by each time biller on each date, and the hourly billing rate of each time
biller, directly to the Company's Vice President and General Counsel, and the
Company will make payment of the amount of the invoice, subject to the maximum
limitation specified above, within 30 days after receipt of the invoice.

         5.   STOCK OPTIONS.  Cosentino is a participant in the Company's 1982
Stock Plan and 1989 Stock Plan (the "Stock Plans").  Under the terms of the
Stock Plans and Cosentino's agreements relating to options to purchase shares of
the Company's common stock, Cosentino is fully vested in options to purchase
380,842 shares of Company common stock, which are listed in Schedule 1 attached
to this Agreement.  Cosentino must exercise his incentive stock options to
purchase 55,843 shares of Company common stock on or before

April 10, 1997; if he does not exercise such options by that date, then such
options will lapse.  If Cosentino rescinds this Agreement and the Cosentino
Release prior to the termination of the applicable rescission period, then he
must exercise his incentive stock options to purchase 9,416 shares of Company
common stock on or before April 10, 1997, and he must exercise his nonqualified
stock options to purchase the remaining 315,583 shares of Company common stock
on or before June 29, 1997; if he does not exercise his incentive stock options
to purchase 9,416 shares of Company common stock (the "9,416 Shares") on or
before April 10, 1997, then the 9,416 Shares will become nonqualified stock
options, and Cosentino must exercise them on or before June 29, 1997.  If
Cosentino does not rescind this Agreement and the Cosentino Release, then the
Board will take the required action to extend the time for Cosentino to exercise
any nonqualified stock options held by him (including the 9,416 Shares) that
were not previously exercised until the earlier of March 31, 2001 or three
months after the Company has given Cosentino notice in writing that he is in
violation of terms of subparagraphs 8.a., 8.b., or 8.c. below.

         6.   INSURANCE CONTINUATION. 

              a.   HEALTH INSURANCE.  Cosentino acknowledges that his
separation from the Company as of March 31, 1997 was a qualifying event under
COBRA and that his right to elect under COBRA health insurance coverage provided
by the Company will terminate no later than September 30, 1998 as provided by
current law.  If the Consultancy Period ends for any reason prior to September
30, 1998, then Cosentino will have the right to

elect under COBRA group health insurance coverage provided by the Company under
such terms as are made available to similarly-situated former employees of the
Company, provided that Cosentino pays 102 percent of the cost of the lowest-cost
group health insurance option provided by the Company as provided by law until
September 30, 1998, or until he obtains other qualifying group coverage or his
COBRA rights terminate for some other reason, if earlier.

              b.   LIFE INSURANCE.  Cosentino will have the right to continue
his group life insurance coverage after March 31, 1997 under Minnesota law under
such terms as are made available to similarly-situated former employees of the
Company, provided that Cosentino pays 102 percent of the cost of that insurance
as provided by law, for 18 months, or until he obtains other qualifying group
coverage or his statutory rights terminate for some other reason, if earlier.

         7.   RETIREMENT PLANS.  Cosentino is a participant in the Minntech
Profit Sharing and Retirement Plan and in the Supplemental Executive Retirement
Plan (the "Retirement Plans").  Cosentino will be entitled to begin drawing his
retirement benefits at the times and under the terms and conditions set forth in
the Retirement Plans.

                        or which is treated by the Company as Confidential
                        Information, will be presumed to be Confidential
                        Information. 

              B.   AGREEMENT NOT TO SOLICIT EMPLOYEES.  Cosentino will not, on
or before April 1, 2001, without the prior written consent of the Company,

Company.  Cosentino will not disregard his obligations of confidence by using
any trade secret or other confidential business and/or technical information of
which he becomes informed during the Consultancy Period or was informed during
his employment to guide him in a search of publications or other publicly
available information, selecting a series of items of knowledge from unconnected
sources, and fitting them together to claim that he did not violate any
agreements set forth in this Agreement.

              D.   SCOPE OF RESTRICTIONS.  The parties intend that, if any
court of competent jurisdiction holds that any restriction in subparagraphs 8.a.
through 8.c. above exceeds the limit of restrictions that are enforceable under
applicable law, then the restriction will nevertheless apply to the maximum
extent that is enforceable under applicable law. 

              E.   DISPUTES.  Any dispute between the parties over whether
Cosentino is in violation of any of the restrictions in subparagraphs 8.a.,
8.b., or 8.c. above will not terminate Cosentino's right to receive Severance
Pay from the Company.

the Company, Cosentino 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.

         11.  COSENTINO REPRESENTATION.  Cosentino represents that, during the
entire period that he was an employee or officer of the Company, he acted in
good faith, had no reasonable cause to believe that his conduct was unlawful,
and reasonably believed that his conduct was in the best interests of the
Company.  The parties intend that the terms used in this paragraph will have the
same meaning as the same terms used in paragraph 302A.531 of the Minnesota
Statutes.

         12.  COMPANY REPRESENTATION.  The Company represents that on the date
of this Agreement no transaction or other event has occurred that would

                        activities as a result of the terms of subparagraphs
                        8.a., 8.b., and 8.c. above.  Nor will it be a violation
                        of this Agreement for Cosentino to inform Company
                        employees who ask him about employment opportunities
                        outside the Company that the terms of paragraph 8.b.
                        above preclude him from engaging in certain activities
                        that could interfere with their employment with the
                        Company.

                   iv.  It will not be a violation of this Agreement for either
                        party to disclose Confidential Separation Information
                        to the Company's auditors, its attorneys, or its
                        directors, officers, employees, or agents who have a
                        legitimate reason to obtain the Confidential Separation
                        Information in the course of performing their duties or
                        responsibilities for the Company.

         14.  NON-DISPARAGEMENT.  Cosentino will not disparage, defame, or

         15.  CLAIMS INVOLVING THE COMPANY.  Cosentino will not recommend or
suggest to any potential claimants or plaintiffs or their attorneys or agents

or divisions, or any of its or their directors, officers, employees, or agents,
nor will Cosentino voluntarily aid, assist, or cooperate 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
Cosentino from giving testimony in response to questions asked pursuant to a
legally enforceable subpoena, deposition notice, or other legal process, during
any legal proceedings involving the Company, any of its affiliates or divisions,
or any of its or their directors, officers, employees, or agents.

         16.  RECORDS, DOCUMENTS, AND PROPERTY.  The Company hereby sells to
Cosentino for $1.00 the personal computer, monitor, printer, scanner, and fax
machine that the Company has previously provided to him.  In addition, the
Company will promptly deliver to Cosentino all scientific and technical books
and journals that were personally purchased by Cosentino and are currently

documents,

financial data, plans, computer disks, computer tapes, and other tangible
property in his possession and all copies thereof belonging to the Company. 
Cosentino acknowledges that all CAD files that have been downloaded onto his
personal computer during his employment with the Company and all copies thereof
constitute property of the Company for purposes of this paragraph 16 and will be
immediately deleted from all computer systems under Cosentino's control. 
Cosentino acknowledges that within 30 days after Cosentino executes this

Schedule 3 attached to this Agreement.

         17.  TIME TO CONSIDER AGREEMENT.  Cosentino understands that he may
take at least 21 calendar days to decide whether to sign this Agreement and the
Cosentino Release, which 21-day period will commence on the date on which
Cosentino receives copies of this Agreement and the Cosentino Release for
review.  Cosentino represents that if he signs this Agreement and the Cosentino
Release before the expiration of the 21-day period, it is because he has decided
that he does not need any additional time to decide whether to sign this
Agreement and the Cosentino Release.

         18.  RIGHT TO RESCIND OR REVOKE.  Cosentino understands that he has
the right to rescind or revoke this Agreement and the Cosentino Release for any

time periods provided by law).  Cosentino understands that this Agreement and
the Cosentino Release will not become effective or enforceable unless and until
he has not rescinded this Agreement and the Cosentino Release and any applicable
rescission period has expired.  Cosentino understands that if he wishes to

         19.  FULL COMPENSATION.  Cosentino and his attorneys, Leonard-Street,
understand that the payments made and other consideration provided by the
Company under this Agreement will fully compensate Cosentino for and extinguish
any and all of the claims Cosentino is releasing in the Cosentino Release,

and all claims for any type of legal or equitable relief.

         20.  NO ADMISSION OF WRONGDOING.  Cosentino understands that this
Agreement does 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 or wrongdoing
against Cosentino.  Cosentino

<PAGE>

                                                                CONFIDENTIAL


will not characterize this Agreement or the payment of any money or other
consideration in accordance with this Agreement as an admission that the Company
has engaged in any improper or unlawful conduct or wrongdoing against him.

         21.  AUTHORITY.  Cosentino represents and warrants that he has the
authority to enter into this Agreement and the Cosentino Release, and that no
causes of action, claims, or demands released pursuant to this Agreement and the
Cosentino Release have been assigned to any person or entity not a party to this
Agreement and the Cosentino Release.

         22.  REPRESENTATION.  Cosentino acknowledges that he has been
represented by his own attorneys in this matter, that he has had a full
opportunity to consider this Agreement and the Cosentino Release, that he has
had a full opportunity to ask any questions that he may have concerning this
Agreement, the Cosentino Release, or the settlement of his potential claims
against the Company, and that he has not relied upon any statements or
representations made by the Company or its attorneys, written or oral, other
than the statements and representations that are explicitly set forth in this
Agreement, the Cosentino Release, the Minntech Release, the Stock Plans and
Cosentino's agreements relating thereto (to the extent not modified by the
action of the Board), the Retirement Plan, and any other employee benefit plans
sponsored by the Company in which Cosentino is a participant.

         23.  SUCCESSORS AND ASSIGNS.  This Agreement will be binding upon and
inure to the benefit of the parties and their respective heirs, representatives,
successors, and assigns, including, but not limited to, a purchaser of
substantially all the business or assets of

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

         24.  INVALIDITY.  In the event that any provision of this Agreement,
the Cosentino 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 Cosentino Release, or the
Minntech Release, and the remaining provisions of this Agreement, the Cosentino
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.

         25.  ENTIRE AGREEMENT.  Before signing this Agreement, the Cosentino
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 representatives considered the matters that are the subject of
this Agreement, the Cosentino Release, and the Minntech Release.  In such
discussions, negotiations, and documents, the parties and their representatives
may have expressed their judgments 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' judgments, 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 respective future rights and remedies. 
Accordingly, this Agreement, the Cosentino Release, the Minntech Release, the
Stock Plans and Cosentino's agreements relating thereto (to the extent not
modified by action of the Board), the Retirement Plans, and any other employee
benefit plans sponsored by the Company in which Cosentino 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 Cosentino Release, the Minntech
Release, the Stock Plans and Cosentino's agreements relating thereto (to the
extent not modified by action of the Board), the Retirement Plans, or any other
employee benefit plans sponsored by the Company in which Cosentino is a
participant are intended by either party to be legally binding, and all other
agreements and understandings between the parties are hereby superseded.

         26.  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.

         27.  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.

         28.  GOVERNING LAW.  This Agreement, the Cosentino Release, and the
Minntech Release will be interpreted and construed in accordance with, and any
dispute or
