ACQUISITIONS

          On September 7, 2001, the Company completed its acquisition of
Minntech, a public company based in Plymouth, Minnesota, in a merger
transaction. Minntech is included in the Company's results of operations for the
portion of fiscal 2002 subsequent to its acquisition on September 7, 2001 and is
excluded from the Company's results of operations for fiscal 2001 and 2000. The
pro forma impact of the acquisition on the Company's results of operations are
reflected in note 3 to the Company's Consolidated Financial Statements.

          Under the terms of the Agreement and Plan of Merger, each share of
Minntech was converted into the right to receive $10.50, consisting of $6.25 in
cash, and a fraction of a share of Cantel common stock having a value of $4.25.
With respect to the stock portion of the consideration, Cantel issued
approximately 2,201,000 shares of common stock in the merger. The total
consideration for the transaction, including transaction costs, was
approximately $78,061,000 (including cash of $41,396,000, shares of Cantel
common stock with a fair market value of $28,144,000, Cantel's existing

                                      - 4 -

investment in Minntech of $725,000 and final transaction costs, including
severance obligations, of approximately $7,796,000). The transaction was
accounted for as a purchase.

          In conjunction with the acquisition, on September 7, 2001 Cantel
entered into new credit facilities to fund the financed portion of the cash
consideration paid in the merger and costs associated with the merger, as well
as to replace the Company's existing working capital credit facilities, as
discussed in note 9 to the Company's Consolidated Financial Statements.

          As a result of the acquisition of Minntech, the Company has added two
new business segments, the Renal Systems Group (see Dialysis Products) and the
Filtration and Separation Systems Group (see Filtration and Separation
Products), both of which represent significant sources of revenue and
profitability.

          On November 1, 2001, the Company's Canadian subsidiary acquired
substantially all of the assets, business and properties of Technimed
Instruments Inc. and Technimed International Inc. (collectively "Technimed") for
approximately $405,000, which included cash of approximately $241,000 and a note
payable in three equal annual installments with a present value of approximately
$164,000. This transaction was accounted for as a purchase.

          Technimed was a private company based in Montreal, Canada which
services medical equipment, including rigid endoscopes and hand-held surgical
instrumentation.

DIALYSIS PRODUCTS

               CONCENTRATES

          Minntech's renal dialysis treatment products include a line of acid
and bicarbonate concentrates used by kidney dialysis centers to prepare
dialysate, a chemical solution that draws waste products from the patient's
blood through a dialyzer membrane during the hemodialysis treatment. The Company
believes it 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.

          In April 2000, Minntech introduced the Renapak 2(TM), an innovative
dry acid concentrate manufacturing system that produces on-demand hemodialysis
concentrates in less than 30 minutes. This product eliminates substantial
freight costs and storage space required for pre-mixed concentrates. Minntech
manufactures and markets the powdered concentrate for the Renapak 2(TM), which
features a convenient quality control and tracking system that allows users to
"peel-and-stick" package labels directly into their concentrate

                                      - 6 -

manufacturing documentation.

               REPROCESSING OF MULTIPLE USE DIALYZERS

          In response to government-mandated cost containment measures, in the
late 1970s many United States dialysis centers began cleaning, disinfecting, and
reusing dialyzers (artificial kidneys) in a process known as "dialyzer reuse"
instead of discarding them after a single use. Approximately 80% of U.S.
dialysis centers employ multiple-use dialyzers.

          Dialyzer reuse is also widely practiced throughout most of Eastern
Europe, the Middle East, Africa and the Asia/Pacific regions. Sales of
reprocessing products have continued to grow in these markets. In order to
further improve support of its Asia/Pacific distributors, Minntech maintains an
Asia/Pacific representative office in Singapore.

          The growth of dialyzer reuse in Western Europe has been limited.
However, due to pending changes to the reimbursement system in several key
markets, such as Germany, the Company believes that this situation should
improve.

          Minntech's dialyzer reprocessing products include the Renatron(R)II
Automated Dialyzer Reprocessing System, the Renalog(R)III Data Management System
and, the RenaClear(TM) Dialyzer Cleaning System, together with Renalin(R) Cold
Sterilant and Renalin(R)100, both peracetic acid based sterilants that replace
less environmentally friendly high-level disinfectants such as formaldehyde.
Actril(R) Ready To Use Cold Sterilant, primarily used as a dialysis machine
disinfectant, and Minncare(R) Cold Sterilant, utilized for water line
disinfection, are also part of Minntech's liquid chemical germicide product
line.

          The Renatron(R) reprocessing system, first introduced in 1982,
provides an automated method of rinsing, cleaning, sterilizing, and testing
dialyzers for multiple use. The Renatron(R)II, the most current version of the
product introduced in 1990, includes a bar-code reader, computer, and
Renalog(R)III software system that provides dialysis centers with automated
record keeping and data analysis capabilities. The Company believes its
Renatron(R) system is faster, easier to use, and more efficient than competitive
automated systems. The Company also believes that the Renatron(R) system is one
of the top selling automated dialyzer reprocessing systems in the world.

          In May 2001 Minntech introduced the Renaclear(TM) Dialyzer Cleaning
System, the first dedicated automated dialyzer cleaning system. The system
removes blood and organic debris from difficult-to-clean dialyzers before
reprocessing, a process known

                                      - 7 -
<Page>

as "precleaning." Precleaning is common in dialysis units because the practice
can help extend the useful clinical life of a dialyzer. When dialyzers are
precleaned by hand, many dialysis facilities remove the dialyzer header caps
(the end caps of a dialyzer) to more effectively rinse out heavy blood debris.
However, opening the dialyzer in this fashion can increase the risk of
contamination of the dialyzer components and damage to the membrane. The
Renaclear(TM) system features a high-powered fluid injector that cleans dialyzer
headers (the two internal ends of a dialyzer) without requiring removal of the
header caps. The Renaclear(TM) Dialyzer Cleaning System is designed for use with
peracetic acid-based Renaclear(TM) Disinfectant.

          Minntech's Renalin(R) Cold Sterilant is a proprietary peracetic
acid-based formula which effectively cleans, disinfects, and sterilizes
dialyzers without the hazardous fumes and disposal problems related to older
glutaraldehyde and formaldehyde reprocessing solutions. The Company believes
Renalin(R) is the leading dialyzer reprocessing solution in the United States.

          Renalin(R)100, a specially packaged formulation of Minntech's cold
sterilant product, was introduced in January 2001. When used with a
Renatron(R)II, converted for use with the Renatron(R)100 Series Conversion Kit,
Renalin(R)100 requires no premixing, which automates the dilution process,
reducing staff set-up time and exposure to vapors. In addition, Renalin(R)100
packaging reduces required storage space by 66% from traditional Renalin(R).

          Minntech manufactures at its Netherlands facility a comprehensive
product line of test strips to measure concentration levels of all
Minntech-produced chemistries. These test strips ensure that the appropriate
concentration of sterilant is maintained throughout the required contact period,
in addition to verifying that all sterilant has been removed from the device or
system prior to patient use.

               ELECTRONICS

          Minntech's major dialysis electronic products are the Sonalarm(R) Foam
Detector, a device that detects air emboli, or bubbles in blood during
hemodialysis; and the Minipump(TM) Hemodialysis Blood Pump, which circulates
blood during hemodialysis. The Sonalarm(R) and the Minipump(TM) are sold to
end-users and (in component form) to other manufacturers of blood processing
equipment.

FILTRATION AND SEPARATION PRODUCTS

               HEMOCONCENTRATORS

          A hemoconcentrator is used by a perfusionist (a health care
professional who operates heart-lung bypass equipment) to concentrate red blood
cells and remove excess fluid from the bloodstream during open-heart surgery.
Because the entire blood volume of the patient passes through the
hemoconcentrator device during an open-heart procedure, the biocompatibility of
the blood-contact components of the device is critical.

          Since 1985 Minntech has manufactured and marketed a line of
hemoconcentrators, and since 1994 the principal product has been its Hemocor
HPH(R) hemoconcentrator. The hemoconcentrator line also features the Hemocor
HPH(R) 700, an adult hemoconcentrator, and the Hemocor HPH(R) Mini, a
hemoconcentrator designed specificalLy for pediatric and neonatal patients.
Minntech currently offers a total of five hemoconcentrator devices to meet the
clinical requirements of neonatal through large adult patients.

          The entire line of Hemocor HPH(R) high performance hemoconcentrator
products contains Minntech's proprietary polysulfone fiber. The Hemocor HPH(R)
line also features a unique "no-rinse" design that allows it to be quickly and
efficiently inserted into the bypass circuit at any time during an open-heart
procedure.

               HEMOFILTERS

          The Renaflo(R) hemofilter is a device that performs hemofiltration in
a slow, continuous blood filtration therapy used to control fluid overload and
acute renal failure in unstable, critically ill patients that cannot tolerate
the rapid filtration rates of conventional hemodialysis. The hemofilter removes
water, waste products and toxins from the circulating blood of patients while
conserving the cellular and protein content of the patient's blood. Minntech's
hemofilter line features no-rinse, polysulfone fiber that requires minimal
set-up time for healthcare professionals. The hemofilter is available in five
different sizes to meet the clinical needs of neonatal through adult patients.

               GAS AND WATER FILTRATION

          In May 2000 Minntech introduced the FiberFlo(R) Membrane Degassing
System, a high-performance hollow fiber module and customized housing for the
addition or removal of gasses from liquid streams. The FiberFlo(R) Membrane
Degassing System was developed for use in pharmaceutical manufacturing,
laboratory, medical, and bioprocessing applications. The polypropylene hollow

                                      - 9 -
<Page>

fiber cartridge degas module features easy operation and maintenance, minimizes
energy consumption, and can be used for CO(2) and O(2) removal, humidification,
pH adjustment, oxygenation, and sparging of gases to solutions.

          Minntech received 510(k) clearance from the United States Food and
Drug Administration ("FDA") in March 1999 to market FiberFlo(R) Hollow Fiber
Capsule Filters for medical applications. The FiberFlo(R) Hollow Fiber Capsule
Filter line, which made its market debut in April 1998, is based on the same
high performance hollow fiber technology used in Minntech's polysulfone
FiberFlo(R) HF Cartridge Filter product line. Capsule filters are used in the
cell and tissue engineering industry, bioprocessing, pharmaceutical
manufacturing, food and beverage processing, cosmetic manufacturing, and
electronics industries to filter spores, bacteria, and pyrogens from aqueous
solutions and gases. FiberFlo(R) Capsule Filters are engineered for point-of-use
applications that require very fine filtration. Their hollow fiber design
provides a surface area that is up to six times larger than traditional pleated
capsule filters on the market. The large surface area provides greater capacity
and longer filter life for the customer. FiberFlo(R) Capsule Filters and
Cartridge Filters are available in a variety of styles, sizes, and
configurations to meet a comprehensive range of customer needs and applications.

          FiberFlo(R) Cartridge Filters are used in high-purity industrial water
systems to filter spores, bacteria, and pyrogens from the fluids. They are also
used in medical device reprocessing to help health care facilities meet
reprocessing water quality guidelines outlined by the American Association of
Medical Instrumentation (AAMI). The cartridge filters feature large surface area
and fine filtration advantages that are similar to Minntech's capsule filter
line.

               DISINFECTANTS AND OTHER

          Minntech's Minncare(R) Cold Sterilant is a liquid sterilant product
that is used to sanitize high-purity water treatment systems. Minncare(R) is
based on Minntech's proprietary peracetic-acid sterilant technology, and is
engineered to clean and disinfect reverse osmosis (RO) membranes and associated
water distribution systems. Minntech has private label agreements for both
Minncare(R) and Actril(R) sterilants with several other companies in the
infection control industry. Minntech also offers a line of ancillary filtration
products, including cleaning solutions, disinfectant test strips, and filtration
housings and accessories.

ENDOSCOPY AND SURGICAL PRODUCTS

          Carsen's principal source of revenue is from the marketing and
distribution to hospitals throughout Canada of specialized endoscopes, surgical
equipment and related accessories, the majority of which are manufactured by
Olympus. Olympus is the world's leading manufacturer of flexible endoscopes and
related products.

          An endoscope is a device comprised of an optical imaging system
incorporated in a flexible or rigid tube that can be inserted inside a patient's
body through a natural opening or through a small incision. Endoscopy, the use
of endoscopes in medical procedures, is a valuable aid in the diagnosis and
treatment of various disorders. Endoscopy enables physicians to study and
digitally capture an image of certain organs and body tissue and, if necessary,
to perform a biopsy (removal of a small piece of tissue for microscopic
analysis).

          A flexible video endoscope consists of a high resolution solid state
image sensor contained in a flexible tube, which can be inserted into
irregularly shaped organs of a patient's body, such as the large intestine. The
control body of a flexible endoscope incorporates a steering mechanism and
contains working channels and is connected to an external light source and
processor, which permits a physician to view inside a patient's body. The
working tip of a flexible endoscope contains a lens and a solid state image
sensor and, in most cases, depending on the application, an outlet for air and
water. Most flexible endoscopes also have internal working channels which enable
accessories such as biopsy forceps to be passed to the tip. The solid state
image sensor enables a live image to be transmitted electronically to a monitor,
which image can be viewed by a physician and nurse as a medical procedure is
being performed. The flexible video endoscope and its related accessories
comprise the majority of Carsen's flexible endoscopy sales.

          A rigid endoscope is a straight and narrow insertion tube consisting
of a series of relay lenses and light transmitting fibers that connect to an
external light source, which permits a surgeon to view inside a patient's body.

          Flexible endoscopes are commonly used for visualization of, and
diagnosing disorders in, the esophagus, stomach, duodenum, and large intestine
(gastroenterology); upper airways and lungs (pneumology); nose and throat (ENT);
bladder, kidney and urinary tract (urology); and uterus (gynecology). Rigid
endoscopes are commonly used for urology, gynecology, orthopedics, ENT and
general surgery, including minimally invasive surgery.

                                     - 11 -
<Page>

          Carsen also distributes various specialized medical instruments and
accessories utilized in both flexible and rigid endoscopy including scissors,
graspers, forceps and other surgical accessories; ambulatory PH and motility
monitoring equipment (which is used for diagnosis of various gastrointestinal
and respiratory disorders); urodynamics monitoring equipment (which is used for
diagnosis of various urinary tract disorders); endoscope disinfection equipment;
insufflators (which deliver and monitor gas to expand abdominal and other
cavities); video monitors, recorders and printers; "cold" light supplies (which
provide light for endoscopy procedures); image processors (which process
digitized endoscopic images); and carts, trolleys and cleaners.

          All of the endoscopes and certain other medical instruments and
accessories distributed by Carsen are manufactured by Olympus. Other medical
products distributed by Carsen are manufactured by Sandhill Scientific, Inc.
(ambulatory PH and motility monitoring equipment), Life-Tech, Inc. (urodynamics
monitoring equipment), Sony of Canada Ltd. (video monitors, recorders and
printers), The Ruhof Corporation (enzymatic cleaners), and MediVators (endoscope
disinfection equipment).

ENDOSCOPE REPROCESSING PRODUCTS

          MediVators' principal source of revenue is from the manufacturing and
sale of endoscope disinfection equipment and related accessories and supplies to
hospitals and clinics through its distribution agreement with Olympus America
Inc. in the United States and internationally through various foreign
distributors.

          MediVators' primary products are the DSD-91E and DSD-201, for which
the original design and configuration utilized in both of these products
received FDA 510(k) clearance in March 1994. The DSD-91E and DSD-201 are
microprocessor controlled dual endoscope disinfection systems. Both systems will
disinfect two endoscopes at a time, can be used on a broad variety of endoscopes
and are programmable by the user. MediVators also manufactures the MV series
which are less expensive single and dual endoscope disinfection units.

          Although endoscopes generally can be manually cleaned and disinfected,
there are many problems associated with such methods including the lack of
uniform cleaning procedures, personnel exposure to disinfectant fumes and
disinfectant residue levels in the endoscope.

          MediVators believes its disinfection equipment offers several
advantages over manual immersion in disinfectants. The disinfectors are designed
to pump disinfectant through all working channels of the endoscope, thus
exposing all areas of the endoscope

                                     - 12 -
<Page>

to the disinfectant, resulting in more thorough and consistent disinfection. The
level of disinfection to be achieved depends upon many factors, principally
contact time, temperature, type and concentration of the active ingredients of
the chemical disinfectant and the nature of the microbial contamination. This
process can also inhibit the build up of residue in the working channels. In
addition, the entire disinfection process can be completed with minimal
participation by the operator, freeing the operator for other tasks, reducing
the exposure of personnel to the chemicals used in the disinfection process and
reducing the risk of infectious diseases. The disinfectors also reduce the risks
associated with inconsistent manual disinfecting.

          In March 2001, MediVators introduced Rapicide(TM) high-level
disinfectant and sterilant, which obtained FDA 510(k) clearance for a high-level
disinfection claim of five minutes at 35 degrees Celsius. This disinfection
contact time is currently the fastest available on any disinfectant product sold
in the United States. The development of Rapicide(TM) adds an additional
consumable to the MediVators' product line.

SCIENTIFIC PRODUCTS

          The Scientific Products segment is comprised of the precision
instruments and the industrial technology equipment distributed by Carsen.

          PRECISION INSTRUMENTS. Carsen distributes Olympus microscopes and
complementary scientific equipment and accessories. Other instruments
distributed by Carsen include Media Cybernetics, Inc. high resolution image
analysis software and hardware; Narishige U.S.A., Inc. micromanipulators (which
enable a viewer to manipulate objects being viewed under a microscope);
Diagnostic Instruments, Inc. and Sony of Canada Ltd. digital cameras for
research microscopy; and optical accessories such as high contrast optics,
objectives (magnifying lenses) and reticules and video calipers (both of which
measure objects being viewed under a microscope).

          The precision instruments distributed by Carsen are sold to hospitals
for cytology, pathology and histology purposes; government laboratories for
research and forensics; and private laboratories, universities and other
educational institutions for research and teaching.

          INDUSTRIAL TECHNOLOGY EQUIPMENT. Carsen distributes three types of
industrial technology equipment that are similar to medical endoscopes, but are
designed for the industrial market for use in remote visual inspection ("RVI").
RVI is the application of endoscopic technology for industrial uses. The
products

                                     - 13 -
<Page>

distributed by Carsen, most of which are manufactured by Olympus, consist of
rigid borescopes (devices that are similar to rigid endoscopes), which use a
series of relay lenses to transmit an image through a stainless steel insertion
tube; fiberscopes (devices that are similar to flexible endoscopes), which use
fiberoptic image carrying bundles to transmit images through a flexible
insertion tube; and video image scopes, which utilize a small, high resolution
solid state image sensor that enables a picture to be transmitted electronically
to a monitor.

          The industrial technology equipment distributed by Carsen is generally
purchased by large industrial companies engaged in the oil and gas, aerospace,
chemical, power generation, mining, forestry, semiconductor and automotive
industries, that require inspections of their machinery or processes for
research and development, measurement, maintenance or quality control.

          Carsen also distributes microscopes to industrial laboratories for
bio-technology, geology, pharmacology, metallography, quality control and
manufacturing applications, and develops and distributes various specialized
machine vision hardware and software, including related engineering services and
accessories utilized in automated industrial applications.

PRODUCT SERVICE

          The majority of the Company's product service revenue and
profitability is generated by Carsen. Carsen operates service centers at its
Markham, Ontario facility, as well as in Montreal, Quebec and Vancouver, British
Columbia that provide warranty and out-of-warranty service and repairs for
endoscopy, surgical, endoscopy reprocessing and scientific products, a majority
of which are distributed by Carsen. The products distributed by Carsen bear a
product warranty that entitles the purchaser to warranty repairs and service at
a nominal charge or no charge during the warranty period. Generally Carsen, and
not the manufacturer of the product, is responsible for the cost of warranty
repairs. The warranty period for these products is generally one year. The
customer pays Carsen on a time and materials basis for out-of-warranty service
of these products.

          MediVators provides a one-year warranty for repairs and service of its
endoscope reprocessing products. Generally, warranty repairs and service related
to the endoscope disinfection equipment are performed by the distributor for
these products. MediVators performs out-of-warranty service of its endoscope
reprocessing products for which the customer pays MediVators on a time and
materials basis.

                                     - 14 -
<Page>

          Minntech operates dialyzer reprocessing centers in Orlando and Boston
that handle all aspects of dialyzer reprocessing, including compliance with
regulatory requirements and record keeping. Dialyzer reprocessing services
consist of the delivery of dialyzers from dialysis centers by Minntech personnel
to the reprocessing center, where they are cleaned, tested, inspected,
sterilized and returned to their facility within a twenty-four hour period.
Dialyzer reprocessing has traditionally required hemodialysis providers to make
a significant investment in dedicated staff, facilities and capital equipment.
By outsourcing this service to Minntech, providers are able to focus resources
on improved patient care.

DISTRIBUTION AGREEMENTS

          OLYMPUS/CARSEN AGREEMENT. The majority of Carsen's sales of endoscopy
and surgical products and scientific products related to precision instruments
have been made pursuant to the Olympus Agreement, and the majority of Carsen's
sales of scientific products related to industrial technology equipment have
been made pursuant to the Olympus Industrial Agreement, under which Olympus has
granted Carsen the exclusive right to distribute the covered Olympus products in
Canada. All products sold by Carsen pursuant to the agreements bear the
trademark of Olympus or its affiliates. Both Olympus agreements expire on March
31, 2004. If Carsen fulfills its obligations under the Olympus Agreement, the
parties will establish new minimum purchase requirements and extend the Olympus
Agreement through March 31, 2006. There are no minimum purchase requirements
under the Olympus Industrial Agreement.

          During the term of the Olympus Agreements and for one year thereafter,
Carsen has agreed that it will not manufacture, distribute, sell or represent
for sale in Canada any products which are competitive with the Olympus products
covered by the Olympus Agreements.

          The Olympus Agreement imposes minimum purchase obligations on Carsen
with respect to each of endoscopy and surgical products and precision
instruments. The aggregate annual minimum purchase obligations for all such
products are approximately $16.9 million and $18.8 million during the contract
years ending March 31, 2003 and 2004, respectively.

          The Olympus Agreements generally prohibit both Olympus and Carsen from
hiring any employee of the other party for a period of one year after the
conclusion of the employee's employment with such other party. This prohibition
remains in effect during the term of the Olympus Agreements and the first year
thereafter.

                                     - 15 -
<Page>

          Subject to an allowance of a 10% shortfall from the minimum purchase
requirements, if Carsen fails to meet such requirements for precision
instruments, then Olympus has the option to terminate or restructure the Olympus
Agreement as it pertains to precision instruments; if Carsen fails to meet such
requirements for endoscopy and surgical products, Olympus has the option to
terminate or restructure the entire Olympus Agreement. Olympus may also
terminate the Olympus Agreement if Carsen breaches its other obligations under
the Olympus Agreement.

          MEDIVATORS/OLYMPUS AGREEMENT. MediVators has a four-year agreement
with Olympus America Inc., which expires on August 1, 2003, under which Olympus
is granted the exclusive right to distribute all of MediVators' endoscope
reprocessing products and related accessories and supplies in the United States
and Puerto Rico. MediVators also has a three-year agreement with Olympus Latin
America which expires on July 21, 2005 under which Olympus is granted the
exclusive right to distribute all of MediVators endoscope reprocessing products
and related accessories and supplies in Latin America; to date such agreement
has not produced significant levels of sales in Latin America. All equipment
sold by Olympus pursuant to these agreements bear both the "Olympus" and
"MediVators" trademarks.

          The MediVators Agreement provides for minimum purchase projections.
Failure by Olympus to achieve the minimum purchase projections in any contract
year gives MediVators the option to terminate the MediVators Agreement. Net
sales to Olympus accounted for 9.5%, 18.4%, and 15.8% of the Company's net sales
in fiscal 2002, 2001 and 2000, respectively.

DISCONTINUED OPERATIONS

          On October 6, 2000, Carsen closed a transaction under an Asset
Purchase Agreement (the "Purchase Agreement") with Olympus pursuant to which
Carsen terminated its consumer products business and sold its inventories of
Olympus consumer products to Olympus. The transaction had an effective date of
July 31, 2000.

          The purchase price for the inventory was $1,026,000, net of
adjustments related to estimated warranty claims and promotional program
expenses payable to Carsen's customers. During fiscal 2001, Carsen also received
additional consideration from Olympus under the Purchase Agreement, including
amounts related to transition services provided by Carsen subsequent to July 31,
2000. Such consideration included (i) fixed cash amounts aggregating
approximately $615,000 and (ii) $619,000, representing twelve and one-half
percent (12 1/2%) of Olympus' net sales of consumer products in Canada in excess
of $8,000,000 during the period from August 1, 2000 through March 31, 2001. No
additional amounts are due from

                                     - 16 -
<Page>

Olympus under the Purchase Agreement.

          The discontinuance of the Consumer Products business has been
reflected as a discontinued operation and is presented separately in the
Company's Consolidated Financial Statements.

MARKETING

          Minntech markets its products in the United States through a direct
sales force and through distributors. Minntech B.V., Minntech's Netherlands
subsidiary, is the base for its European operations. Minntech Japan K.K.,
Minntech's Japan subsidiary, and Minntech Singapore, a branch office of Minntech
B.V., serve the Asia/Pacific market.

          MediVators sells its endoscope reprocessing products in the United
States under an exclusive distribution agreement with Olympus, and
internationally through various foreign distributors.

          Carsen markets its products for each business segment through
separate, direct sales forces comprised of its own employees.

          Most of the Company's direct sales forces are compensated on a salary
and commission basis.

EFFECT OF CURRENCY FLUCTUATIONS AND TRADE BARRIERS

          A portion of the Company's products are imported from the Far East and
Western Europe, the Company's United States subsidiaries sell a portion of their
products outside of the United States, and Minntech's Netherlands subsidiary
sells a portion of its products outside of the European Union. Consequently, the
Company's business could be materially and adversely affected by the imposition
of trade barriers, fluctuations in the rates of exchange of various currencies,
tariff increases and import and export restrictions, affecting the United
States, Canada and the Netherlands.

          Carsen imports a substantial portion of its products from the United
States and pays for such products in United States dollars, and Carsen's
business could be materially and adversely affected by the imposition of trade
barriers, fluctuations in the rates of currency exchange, tariff increases and
import and export restrictions between the United States and Canada.
Additionally, Carsen's financial statements are translated using the accounting
policies described in note 2 to the Consolidated Financial Statements.
Fluctuations in the rates of currency exchange between the United States and
Canada had an adverse impact in fiscal 2002 compared with fiscal 2001, and in
fiscal 2001 compared with fiscal

                                     - 17 -
<Page>

2000, upon the Company's results of operations and stockholders' equity, as
described in Management's Discussion and Analysis of Financial Condition and
Results of Operations.

          Financial statements of the Netherlands subsidiary are translated
using the accounting policies described in Note 2 to the Consolidated Financial
Statements. Fluctuations in the rates of currency exchange between the European
Union and the United States had an adverse impact in fiscal 2002 upon the
Company's results of operations, as described in Management's Discussion and
Analysis of Financial Condition and Results of Operations.

          The functional currency of Minntech's Japan subsidiary is the Japanese
yen. Changes in the value of the Japanese yen relative to the United States
dollar since the acquisition of Minntech on September 7, 2001 did not have a
significant impact upon either the Company's results of operations or the
translation of the balance sheet, primarily due to the fact that the Company's
Japanese subsidiary accounts for a relatively small portion of consolidated net
sales, earnings and net assets.

COMPETITION

          The Company distributes substantially all of its products in highly
competitive markets, which contain many products available from nationally and
internationally recognized competitors of the Company. Many of such competitors
have greater financial and technical resources than the Company and are
well-established, with reputations for success in the sale and service of their
products. In addition, certain companies have developed or may be expected to
develop technologies or products that could directly or indirectly compete with
the products manufactured and distributed by the Company. The Company competes
with manufacturers who distribute and service their own products and have
greater financial and technical resources than the Company and, as
manufacturers, may have certain other competitive advantages over the Company.

          The Company believes that the world-wide reputation for the quality
and innovation of its products among consumers, the Company's reputation for
providing quality product service, particularly with respect to endoscopy and
surgical and endoscope reprocessing products, the numerous customer contacts
developed during its lengthy service as a distributor of Olympus products and
the distribution arrangement for certain MediVators endoscope reprocessing
products with Olympus, give the Company a competitive advantage with respect to
certain of its products.

                                     - 18 -
<Page>

          Two of Minntech's competitors (Fresenius Medical Care AG ("Fresenius")
and HDC Medical, Inc.) have introduced peracetic acid-based dialyzer
reprocessing germicides, entering a market previously dominated by Minntech's
Renalin(R) Cold Sterilant product. However, Renalin(R) remains the only
reprocessing chemical that has been validated for use with the Renatron(R)
dialyzer reprocessing system and cleared for marketing as such under section
510(k) of the Federal Food, Drug and Cosmetic Act. Renalin(R) is also the only
dialyzer reprocessing germicide that carries a sterilization claim in the United
States market. Minntech has informed its Renatron(R) customers that it is unable
to guarantee the integrity, reliability, and chemical interaction of alternative
germicides with the Renatron(R) system. Minntech believes that this validation,
coupled with Minntech's extensive dialyzer reprocessing education,
administration, and technical support services, are strong competitive
advantages for its product. However, the competitive price pressures introduced
by these new germicides has adversely impacted Minntech's current dialyzer
reprocessing chemical market share.

          Within the dialysis industry manufacturers have been acquiring chains
of dialysis treatment centers over the past several years. These manufacturers
have a built-in customer base for their products. However, Minntech views its
manufacturer-only status as a competitive market advantage. Minntech believes
that many dialysis treatment providers do not want to purchase hemodialysis
supplies from manufacturers who also provide dialysis service and are, in
effect, their competitors.

          Two of the Company's competitors (Gambro Healthcare, Inc. and
Fresenius) have made public disclosures of their intent to increase the use of
single-use dialyzers which, at some dialysis centers owned by these companies,
could impact Minntech's Renatron reprocessing equipment at such centers.
Presently, the utilization of single use dialyzers continues to be significantly
more expensive than dialyzer reuse and, as such, the number of Minntech-supplied
reuse programs is not expected to decrease significantly.

MARKET CONDITIONS

          Minntech's ability to sell its products depends in part on the extent
to which reimbursement for the cost of these 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
healthcare 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 the

                                     - 19 -
<Page>

providers contract to provide comprehensive health care for a fixed cost per
person. Moreover, 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.

GOVERNMENT REGULATION

          Many of Minntech's and MediVators' products are subject to regulation
by the FDA, which regulates the testing, manufacturing, packaging, distribution
and marketing of medical devices in the United States. Certain of Minntech's and
MediVators' products may be regulated by other governmental or private agencies,
including the Environmental Protection Agency ("EPA"), Underwriters Lab, Inc.,
and comparable agencies in certain foreign countries. The FDA and other agency
clearances generally are required before Minntech or MediVators can market new
products in the United States or make significant changes to existing products.
The FDA also has the authority to require a recall or modification of products
in the event of a defect.

          The Food, Drug and Cosmetic Act of 1938 and Safe Medical Device Act of
1990, each as amended, also require compliance with specific manufacturing and
quality assurance standards. The regulations also require that each manufacturer
establish a quality assurance program by which the manufacturer monitors the
design and manufacturing process and maintains records which show compliance
with the FDA regulations and the manufacturer's written specifications and
procedures relating to the devices. The FDA inspects medical device
manufacturers for compliance with their Quality Systems Regulations ("QSR's").
Manufacturers that fail to meet the QSR's may be issued reports or citations for
non-compliance. The Company was inspected by the FDA in January 2002 and
November 2000 with no warning letters issued.

          In addition, many of Minntech's and MediVators' products must meet the
requirements of the European Medical Device Directive ("MDD") for their sale
into the European Union. In June 2002, Minntech and MediVators were inspected
and received notification that their products continue to meet these
requirements. This certification allows Minntech and MediVators to affix the CE
mark to its products and to freely distribute such products throughout the
European Union. Federal, state and foreign regulations regarding the manufacture
and sale of Minntech's and MediVators' products are subject to change. Neither
Minntech nor MediVators can predict what impact, if any, such changes might have
on their business.

                                     - 20 -
<Page>

          Carsen's endoscopy and surgical products and endoscope reprocessing
products are subject to regulation by Health Canada - Therapeutic Products
Directorate ("TPD"), which regulates the distribution and marketing of medical
devices in Canada. Certain of Carsen's products may be regulated by other
governmental or private agencies, including Canadian Standards Agency ("CSA").
TPD and other agency clearances generally are required before Carsen can market
new medical products in Canada. TPD also has the authority to require a recall
or modification in the event of defect. In order to market its medical products
in Canada, Carsen is required to hold a Medical Device Establishment License, as
well as certain medical device licenses by product, as provided by TPD. In
addition, Minntech and MediVators have received drug identification numbers and
Carsen has applied to TPD for a drug establishment license which is required
before Carsen can distribute Minntech's and MediVators' sterilant/disinfectant
products in Canada.

PATENTS AND PROPRIETARY RIGHTS

          Minntech holds rights under 60 patents worldwide covering its products
or components thereof. At October 3, 2002, Minntech also had a total of 35
pending patent applications in the United States and in foreign countries.
Minntech also holds rights under 248 trademark registrations worldwide and had
44 trademark applications pending as of October 3, 2002.

          Minntech believes that patent protection is a significant factor in
maintaining its market position, but the rapid changes of technology in
reprocessing, hollow fiber membranes, dialysis, liquid and dry chemical
sterilants and other areas in which Minntech competes may limit the value of
Minntech's existing patents.

          MediVators' current disinfector products, including the DSD-91E,
DSD-201 and the MV Series tabletop systems, utilize certain know-how developed
within the Company but have no patent protection. MediVators holds rights under
five trademark registrations worldwide and had one trademark application pending
as of October 3, 2002. In addition, MediVators holds rights under two patents
and two pending patent applications covering its products or components thereof.

          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 may also obtain patents that the Company

                                     - 21 -
<Page>

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.

BACKLOG

          On October 3, 2002, the Company's consolidated backlog was
approximately $954,000, compared with approximately $1,773,000 on October 5,
2001.

EMPLOYEES

          As of October 3, 2002, the Company employed 541 persons. Of the
Company's employees, 381 are located in the United States, 120 are located in
Canada, 31 are located in Europe and 9 are located in the Far East; 26 are
executives and/or managers, 103 are engaged in sales and marketing functions, 33
are engaged in customer service, 46 are engaged in product service, 245 are
engaged in manufacturing, shipping and warehouse functions, 61 perform various
administrative functions and 27 are engaged in research and development.

          None of the Company's employees are represented by labor unions. The
Company considers its relations with its employees to be satisfactory.

 (1) Consolidated statements of income data for fiscal 1998 through 2001 have
     been reclassified from amounts previously reported to reflect shipping and
     warehouse expenses in cost of sales. Such reclassifications are consistent
     with the fiscal 2002 presentation and had no impact upon earnings.

 (2) Includes for fiscal 1999 costs of $467,000 associated with the
     discontinuance of MediVators' medical sharps disposal business, of which
     $452,000 pertained to an inventory write- off and was therefore recorded to
     cost of sales. The charge of $467,000 reduced basic and diluted earnings
     per share from continuing operations by $0.07. Without this charge, basic
     and diluted earnings per share from continuing operations for fiscal 1999,
     as adjusted, would have been $0.32 and $0.31, respectively.

 (3) Per share and share amounts for fiscal 1998 through 2001 have been adjusted
     from amounts previously reported to reflect a three-for-two stock split
     effected in the form of a 50% stock dividend paid in May 2002. Such
     adjustments are consistent with the fiscal 2002 presentation.

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

RESULTS OF CONTINUING OPERATIONS

          The results of continuing operations reflect primarily the results of
Minntech, MediVators and Carsen .

          Reference is made to (i) the discontinuance of the Company's Consumer
Products business, as more fully described in Item 1, "Business," and in note 8
to the Consolidated Financial Statements, (ii) the impact on the Company's
results of operations of a weaker Canadian dollar against the United States
dollar during fiscal 2002 compared with fiscal 2001 and during fiscal 2001
compared with fiscal 2000 (decrease in value of approximately 3% during each of
the above periods), (iii) critical accounting policies of the Company, as more
fully described in note 2 to the Consolidated Financial Statements, as well as
elsewhere in this Management's Discussion and Analysis of Financial Condition
and Results of Operations, (iv) 3,143,000 additional shares issued in connection
with a three-for-two stock split effected in the form of a 50% stock dividend
paid to stockholders in May 2002, as more fully described in note 1 to the
Consolidated Financial Statements, and (v) the Company's acquisition of Minntech
in September 2001, as more fully described in Item 1, "Business," and in notes 3
and 9 to the Consolidated Financial Statements.

          Minntech is reflected in the Company's results of operations for the
portion of fiscal 2002 subsequent to its acquisition on September 7, 2001, and
is not reflected in the results of operations for fiscal 2001 or fiscal 2000.
The acquisition of Minntech has added two new operating segments to the Company,
Dialysis Products and Filtration and Separation Products. Additionally, Minntech
also contributes to the Company's Product Service operating segment. Discussion
herein of the Company's pre-existing businesses refers to the operations of
Cantel, Carsen and MediVators, but excluding the impact of the Minntech
acquisition.

     FISCAL 2002 COMPARED WITH FISCAL 2001

          Net sales increased by $70,999,000, or 144.9%, to $119,994,000 in
fiscal 2002, from $48,995,000 in fiscal 2001. Net sales contributed by Minntech
for fiscal 2002 were $71,938,000; without the Minntech acquisition, net sales of
the Company's pre-existing businesses would have decreased by $939,000, or 1.9%,
to $48,056,000 for fiscal 2002. Net sales were adversely impacted in fiscal 2002
compared with fiscal 2001 by approximately $1,113,000 due to the translation of
Carsen's net sales using a weaker Canadian dollar against the United States
dollar.

          The decrease in sales of the Company's pre-existing businesses was
attributable to the decreased sales of endoscopy and surgical products,
partially offset by an increase in sales of endoscope reprocessing products and
product service. The decrease in sales of endoscopy and surgical products was
due to a decrease in demand, including the adverse impact of healthcare funding
issues in Canada as well as intensified competition which the Company expects to
continue. Healthcare funding in Canada is dependent upon governmental
appropriations and the Company cannot ascertain what impact the funding
situation will have on future

                                     - 29 -
<Page>

sales of endoscopy and surgical products and scientific products. The increase
in sales of endoscope reprocessing products was primarily due to an increase in
demand in the United States. The increase in sales of product service was
primarily due to an increase in demand and marketshare in Canada.

          The Company believes that it has the opportunity to continue
increasing its marketshare in the endoscope reprocessing segment. The majority
of its product service segment is located in Canada where the Company's
marketshare in its flexible endoscope service business is substantial;
therefore, growth opportunities for its existing service business may be limited
without the addition of new product servicing opportunities.

          Gross profit increased by $27,460,000, or 144.4%, to $46,476,000 in
fiscal 2002, from $19,016,000 in fiscal 2001. Gross profit contributed by
Minntech for fiscal 2002 was $29,059,000; without the impact of the Minntech
acquisition, gross profit of the Company's pre-existing businesses would have
decreased by $1,599,000, or 8.4%, to $17,417,000 for fiscal 2002.

          Gross profit as a percentage of net sales was 38.7% in fiscal 2002,
compared with 38.8% in fiscal 2001. During fiscal 2002, gross profit was
adversely impacted by a $427,000 charge to cost of sales related to the sale of
inventories which carried a step-up in value recorded as a result of purchase
accounting; such charge reduced gross profit percentage by 0.4% for fiscal 2002.
Minntech's gross profit as a percentage of net sales was 40.4% for fiscal 2002;
without the impact of the Minntech acquisition, gross profit as a percentage of
net sales for fiscal 2002 would have been 36.2%.

          The lower gross profit percentage from the Company's pre-existing
businesses for fiscal 2002, as compared with fiscal 2001, was primarily
attributable to the adverse impact of a weaker Canadian dollar relative to the
United States dollar, since the Company's Canadian subsidiary purchases
substantially all of its products in United States dollars and sells its
products in Canadian dollars; a higher gross profit percentage in 2001 due to a
buy-in of endoscopes prior to receiving a supplier price increase (such
endoscopes were sold during fiscal 2001); increased competition in endoscopy and
surgical products; and sales mix associated with endoscope reprocessing products
and product service, including the increased manufacturing and warranty costs
associated with the Company's new DSD-201 endoscope reprocessing unit.

          Selling expenses as a percentage of net sales were 12.3%

                                     - 30 -
<Page>

for fiscal 2002, compared with 11.6% for fiscal 2001. Without the impact of the
Minntech acquisition, selling expenses as a percentage of net sales would have
been 13.4% for fiscal 2002. The increase in selling expenses as a percentage of
net sales from the Company's pre-existing businesses was primarily attributable
to lower than expected sales at Carsen, an increase in personnel at Carsen and
expanded marketing efforts to support MediVators' domestic sales of endoscope
reprocessing products.

          General and administrative expenses increased by $9,150,000 to
$14,560,000 for fiscal 2002, from $5,410,000 for fiscal 2001. General and
administrative expenses incurred by Minntech for fiscal 2002 were $8,536,000;
without the Minntech acquisition, general and administrative expenses of the
Company's pre-existing businesses would have increased by $614,000 for fiscal
2002, principally due to the addition of business development personnel and
related expenses and costs associated with the Company's listing of its Common
Stock on the New York Stock Exchange.

          Research and development expenses increased by $2,902,000 to
$3,851,000 for fiscal 2002, from $949,000 for fiscal 2001. Research and
development expenses incurred by Minntech for fiscal 2002 were $2,637,000;
without the Minntech acquisition, research and development expenses of the
Company's pre-existing businesses would have increased by $265,000 for fiscal
2002, principally due to costs related to MediVators' new endoscope reprocessing
unit. The Company anticipates research and development expenses to increase in
fiscal 2003 primarily due to costs associated with two specific projects;
however, such increase is not expected to exceed 15.0% relative to the fiscal
2002 level of research and development expenses (assuming that Minntech had been
included in the Company's results of operations for all of fiscal 2002).

          Interest expense was $2,176,000 for fiscal 2002, compared with
interest income of $42,000 for fiscal 2001. This change in interest was
attributable to the Company's borrowings under its new credit facilities entered
into during September 2001 to fund a portion of the Minntech acquisition.

          Income from continuing operations before income taxes increased by
$4,123,000, or 58.8%, to $11,130,000 for fiscal 2002, from $7,007,000 for fiscal
2001.

          The consolidated effective tax rate on operations was 35.7% and 40.7%
for fiscal 2002 and 2001, respectively. In conjunction with the purchase
accounting for the acquisition of Minntech, Cantel eliminated the valuation
allowances against its deferred tax assets related to the NOLs accumulated in
the United States. Therefore, for all periods subsequent to September 7,

                                     - 31 -
<Page>

2001, the Company has provided in its results of operations income tax expense
for its United States operations at the statutory tax rate; however, actual
payment of U.S. federal income taxes will reflect the benefits of the
utilization of the NOLs.

          The Company's results of operations for fiscal 2002 also reflect
income tax expense for its international subsidiaries at their respective
statutory rates. Such international subsidiaries include the Company's
subsidiaries in Canada, the Netherlands and Japan, which had effective tax rates
during fiscal 2002 of approximately 38.7%, 26.5% and 44.8%, respectively. The
operations of the Company's subsidiaries in the Netherlands and Japan were part
of the Minntech acquisition and are therefore included in the Company's results
of operations only since September 7, 2001.

          For fiscal 2001, income taxes consist primarily of taxes imposed on
the Company's Canadian subsidiary which had an effective tax rate of
approximately 41.6%. The consolidated effective tax rate in fiscal 2001 was
lower than the Canadian effective tax rate due to the fact that income generated
by the United States operations was substantially offset by federal tax benefits
resulting from the utilization of NOLs.

          In fiscal 2003, the Company expects a reduction in its Canadian
effective tax rate due to enacted reductions in both Canadian federal and
provincial income tax rates. However, the Company's overall effective tax rate
for fiscal 2003 is subject to the progressive tax rate structure in the
Netherlands, as well as changes caused by the geographic mix of pretax income.

     FISCAL 2001 COMPARED WITH FISCAL 2000

          Net sales increased by $7,698,000, or 18.6%, to $48,995,000 in fiscal
2001, from $41,297,000 in fiscal 2000. Net sales were adversely impacted in
fiscal 2001 compared with fiscal 2000 by approximately $1,381,000 due to the
translation of Carsen's net sales using a weaker Canadian dollar against the
United States dollar.

          This increase in net sales was attributable to the increased sales of
the Company's endoscopy and surgical products, endoscope reprocessing products
and product service business segments. For fiscal 2001, the increased sales of
endoscopy and surgical products were due primarily to an increase in demand, a
portion of which was attributable to the introduction of new flexible endoscopy
products, and selling price increases. The increased sales of endoscope
reprocessing products were primarily attributable to an increase in demand for
endoscope reprocessing products in the United States. The increased sales of
product service were primarily attributable to an increase in demand and

                                     - 32 -
<Page>

selling price increases.

          Gross profit increased by $3,288,000, or 20.9%, to $19,016,000 in
fiscal 2001, from $15,728,000 in fiscal 2000. Gross profit was adversely
impacted in fiscal 2001 compared with fiscal 2000 by approximately $509,000 due
to the translation of Carsen's gross profit using a weaker Canadian dollar
against the United States dollar.

          Gross profit as a percentage of net sales increased to 38.8% in fiscal
2001, from 38.1% in fiscal 2000. The higher gross profit percentage for fiscal
2001 was primarily attributable to a buy-in of endoscopes prior to receiving a
supplier price increase, which endoscopes were sold during fiscal 2001; selling
price increases in endoscopy and surgical products and product service; and
favorable sales mix associated with product service and scientific products.
Partially offsetting these increases in gross profit percentage was the adverse
impact of a weaker Canadian dollar relative to the United States dollar, since
the Company's Canadian subsidiary purchases substantially all of its products in
United States dollars and sells its products in Canadian dollars.

          Selling expenses as a percentage of net sales were 11.6% for fiscal
2001, compared with 12.6% for fiscal 2000. The decrease in selling expenses as a
percentage of net sales was primarily attributable to the effect of the
increased sales against the fixed portion of selling expenses.

          General and administrative expenses increased by $867,000 to
$5,410,000 for fiscal 2001, from $4,543,000 for fiscal 2000. The increase
reflects additional personnel and increases in incentive compensation, profit
sharing contributions, rent and amortization of computer software.

          Research and development expenses increased by $113,000 to $949,000
for fiscal 2001, from $836,000 for fiscal 2000. This increase was primarily due
to additional personnel required for new products including the DSD-201 and
Rapicide(TM).

          Interest income was $42,000 in fiscal 2001, compared with interest
expense of $225,000 in fiscal 2000. This change in interest was attributable to
interest income earned on cash and cash equivalents during fiscal 2001, compared
with interest expense on outstanding borrowings during fiscal 2000.

          Income from continuing operations before income taxes increased by
$2,091,000, or 42.5%, to $7,007,000 for fiscal 2001, from $4,916,000 for fiscal
2000.

          Income taxes consist primarily of taxes imposed on the

                                     - 33 -
<Page>

Company's Canadian operations. The effective tax rate on Canadian operations was
41.6% and 43.9% for fiscal 2001 and 2000, respectively. For fiscal 2001 and
2000, the consolidated effective tax rate is lower than the Canadian effective
tax rate due to the fact that income generated by the United States operations
is substantially offset by tax benefits resulting from the utilization of net
operating loss carryforwards for federal income tax purposes.

LIQUIDITY AND CAPITAL RESOURCES

          At July 31, 2002, the Company's working capital was $37,824,000,
compared with $16,669,000 at July 31, 2001. This increase in working capital was
primarily due to the acquisition of Minntech.

          Net cash provided by operating activities was $11,302,000, $1,342,000
and $4,668,000 for fiscal 2002, 2001 and 2000, respectively. In fiscal 2002, net
cash provided by operating activities was primarily due to income from
continuing operations after adjusting for depreciation and amortization and
deferred income taxes, and decreases in accounts receivable and inventories,
partially offset by decreases in accounts payable and accrued expenses and
income taxes payable. In fiscal 2001, net cash provided by operating activities
was primarily due to income from continuing operations after adjusting for
depreciation and amortization, and an increase in income taxes payable,
partially offset by increases in accounts receivable and inventories. In fiscal
2000, net cash provided by operating activities was primarily due to income from
continuing operations after adjusting for depreciation and amortization and
deferred income taxes, and decreases in inventories and accounts receivable.

          Net cash used in investing activities was $31,541,000 in fiscal 2002,
compared with net cash provided by investing activities of $1,135,000 in fiscal
2001 and net cash used in investing activities of $1,392,000 in fiscal 2000. In
fiscal 2002, net cash used in investing activities was primarily for the
acquisition of Minntech and capital expenditures. In fiscal 2001, net cash
provided by investing activities was primarily due to proceeds from the
discontinued operations, partially offset by purchases of available-for-sale
securities, professional fees related to the Minntech acquisition (such fees are
included within other, net) and capital expenditures. In fiscal 2000, net cash
used in investing activities was primarily due to an increase in the net assets
related to the discontinued operations and capital expenditures. During fiscal
2003, the Company anticipates an increase in the level of its capital
expenditures, primarily at Minntech.

          Net cash provided by financing activities was $27,754,000

                                     - 34 -
<Page>

in fiscal 2002 and $404,000 in fiscal 2001, compared with net cash used in
financing activities of $1,641,000 in fiscal 2000. In fiscal 2002, net cash
provided by financing activities was primarily attributable to borrowings under
the Company's new credit facilities for the Minntech acquisition, net of related
debt issuance costs, partially offset by repayments under these credit
facilities. In fiscal 2001, net cash provided by financing activities was
primarily due to proceeds from the exercise of stock options. In fiscal 2000,
net cash used in financing activities was primarily due to net repayments under
a prior credit facility.

          At July 31, 2001, the Company had a credit facility which provided for
(i) a $2,500,000 revolving credit facility for Cantel and MediVators, (ii) a
$5,000,000 (United States dollars) revolving credit facility for Carsen and
(iii) a $12,500,000 acquisition facility available to Cantel and MediVators for
permitted acquisitions in the United States. At July 31, 2001, the Company had
no outstanding borrowings under this credit facility.

          In conjunction with the acquisition of Minntech on September 7, 2001,
the Company entered into new credit facilities to fund the financed portion of
the cash consideration paid in the merger and costs associated with the merger,
as well as to replace the Company's existing working capital credit facilities.
The new credit facilities include (i) a $25,000,000 senior secured amortizing
term loan facility from a consortium of U.S. lenders (the "Term Loan Facility")
used by Cantel to finance a portion of the Minntech acquisition, (ii) a
$17,500,000 senior secured revolving credit facility from the U.S. lenders (the
"U.S. Revolving Credit Facility") used by Cantel to finance a portion of the
Minntech acquisition as well as being available for future working capital
requirements for the U.S. businesses of Cantel, including Minntech and
MediVators (the "U.S. Borrowers") and (iii) a $5,000,000 (United States dollars)
senior secured revolving credit facility for Carsen (the "Canadian Borrower")
with a Canadian bank (the "Canadian Revolving Credit Facility") available for
Carsen's future working capital requirements. Each of the Term Loan Facility,
the U.S. Revolving Credit Facility and the Canadian Revolving Credit Facility
(collectively the "Credit Facilities") expire on September 7, 2006.

          Borrowings under the Credit Facilities bear interest at rates ranging
from .75% to 2.00% above the lender's base rate, or at rates ranging from 2.00%
to 3.25% above the London Interbank Offered Rate ("LIBOR"), depending upon the
Company's consolidated ratio of debt to earnings before interest, taxes,
depreciation and amortization ("EBITDA"). The base rates associated with the
U.S. lenders and the Canadian lender were 4.75% and 4.50%, respectively, at
October 3, 2002, and the LIBOR rates ranged from 1.66% to 1.80% at October 3,
2002. The margins applicable to the Company's

                                     - 35 -
<Page>

outstanding borrowings at October 3, 2002 are 1.5% above the lender's base rate
and 2.75% above LIBOR. In order to protect its interest rate exposure, the
Company entered into a three-year interest rate cap agreement expiring on
September 7, 2004 covering $12,500,000 of borrowings under the Term Loan
Facility, which caps LIBOR on this portion of outstanding borrowings at 4.50%.
The Credit Facilities also provide for fees on the unused portion of such
facilities at rates ranging from .30% to .50%, depending upon the Company's
consolidated ratio of debt to EBITDA.

          The Term Loan Facility and the U.S. Revolving Credit Facility provide
for available borrowings based upon percentages of the U.S. Borrowers' eligible
accounts receivable and inventories; require the U.S. Borrowers to meet certain
financial covenants; are secured by substantially all assets of the U.S.
Borrowers (including a pledge of the stock of Minntech and MediVators owned by
Cantel and 65% of the outstanding shares of Carsen stock owned by Cantel); and
are guaranteed by Minntech and MediVators. The Canadian Revolving Credit
Facility provides for available borrowings based upon percentages of the
Canadian Borrower's eligible accounts receivable and inventories; requires the
Canadian Borrower to meet certain financial covenants; and is secured by
substantially all assets of the Canadian Borrower.

          On September 7, 2001, the Company borrowed $25,000,000 under the Term
Loan Facility and $9,000,000 under the U.S. Revolving Credit Facility in
connection with the acquisition of Minntech. At July 31, 2002, the Company had
$28,500,000 outstanding under its Credit Facilities, including $23,500,000 under
the Term Loan Facility. Subsequent to July 31, 2002, the Company repaid an
additional $1,000,000 under its Credit Facilities; therefore, at October 3,
2002, the Company had $27,500,000 outstanding under its credit facilities,
including $23,000,000 under the Term Loan Facility. Amounts repaid by the
Company under the Term Loan Facility may not be re-borrowed.

          Aggregate annual required maturities of the Credit Facilities over the
next five years and thereafter are as follows:

          The Company has determined that it will repatriate minimal amounts of
existing and future accumulated profits from its international locations until
existing NOLs are exhausted, which the Company has determined to be
approximately through fiscal 2004. Notwithstanding this strategy, the Company
believes that its current cash position, anticipated cash flows from operations,
(including its U.S. operations) and the funds available under its revolving
credit facilities will be sufficient to satisfy the Company's cash operating
requirements for the foreseeable future based upon its existing operations,
including the payment of remaining liabilities from the Minntech acquisition. At
October 3, 2002, approximately $12,479,000 was available under the revolving
credit facilities.

          During fiscal 2002 compared with fiscal 2001, the average value of the
Canadian dollar decreased by approximately 3% relative to the value of the
United States dollar. Changes in the value of the Canadian dollar against the
United States dollar affect the Company's results of operations because the
Company's Canadian subsidiary purchases substantially all of its products in
United States dollars and sells its products in Canadian dollars. Such currency
fluctuations also result in a corresponding change in the United States dollar
value of the Company's assets that are denominated in Canadian dollars.

          Under the Canadian Revolving Credit Facility, Carsen has a $20,000,000
(United States dollars) foreign currency hedging facility which is available to
hedge against the impact of such currency fluctuations on purchases of
inventories. Total commitments for foreign currency forward contracts under this
facility amounted to $6,774,000 (United States dollars) at October 3, 2002 and
cover a portion of the Canadian subsidiary's projected purchases of inventories
through February 2003. The weighted average exchange rate of the forward
contracts open at October 3,

                                     - 37 -
<Page>

2002 was $1.5739 Canadian dollar per United States dollar, or $.6353 United
States dollar per Canadian dollar. The exchange rate published by the Wall
Street Journal on October 3, 2002 was $1.5921 Canadian dollar per United States
dollar, or $.6281 United States dollar per Canadian dollar.

          Since the acquisition of Minntech on September 7, 2001 until the end
of fiscal 2002, the value of the euro increased by approximately 8% relative to
the value of the United States dollar. Changes in the value of the euro against
the United States dollar affect the Company's results of operations because a
portion of the net assets of Minntech's Netherlands subsidiary are denominated
and ultimately settled in United States dollars but must be converted into its
functional euro currency. During the portion of fiscal 2002 subsequent to the
Minntech acquisition, such strengthening of the euro relative to the United
States dollar had an adverse impact upon the Company's results of operations.
Such currency fluctuations also result in a change in the United States dollar
value of the Company's assets that are denominated in euros.

          In order to hedge against the impact of fluctuations in the value of
the euro relative to the United States dollar, the Company enters into
short-term contracts to purchase euros forward. There was one foreign currency
forward contract amounting to EURO 4,500,000 at October 3, 2002 which covers a
portion of the net assets of Minntech's Netherlands subsidiary which are
denominated in United States dollars. Such contract expires on October 31, 2002.
Under its Credit Facilities, such contracts to purchase euros may not exceed
$12,000,0000 in an aggregate notional amount at any time.

          Effective August 1, 2000, the Company adopted Statement of Financial
Accounting Standards No. 133, as amended, "ACCOUNTING FOR DERIVATIVE INSTRUMENTS
AND HEDGING ACTIVITIES" ("SFAS 133"). In accordance with SFAS 133, all of the
Company's foreign currency forward contracts are designated as hedges.
Recognition of gains and losses related to the Canadian hedges is deferred
within other comprehensive income until settlement of the underlying
commitments, and realized gains and losses are recorded within cost of sales
upon settlement. Gains and losses related to the hedging contracts to buy euros
forward is immediately realized within general and administrative expenses due
to the short-term nature of such contracts.

          For purposes of translating the balance sheet, at July 31, 2002
compared to September 7, 2001, the value of the euro increased by approximately
8% compared to the value of the United States dollar, thereby causing a decrease
in the negative cumulative foreign currency translation adjustment during such
period. Partially offsetting this change was a 3% decrease in the

                                     - 38 -
<Page>

value of the Canadian dollar relative to the value of the United States dollar
at July 31, 2002 compared to July 31, 2001, which caused an increase to the
negative cumulative foreign currency translation adjustment during fiscal 2002.
The net impact of these currency movements was an overall decrease in the
negative cumulative foreign currency translation adjustment during fiscal 2002
of $352,000, thereby increasing stockholders' equity.

          Changes in the value of the Japanese yen relative to the United States
dollar since the acquisition of Minntech on September 7, 2001 did not have a
significant impact upon either the Company's results of operations or the
translation of the balance sheet, primarily due to the fact that the Company's
Japanese subsidiary accounts for a relatively small portion of consolidated net
sales, earnings and net assets.

          As of July 31, 2002, the Company had NOLs for domestic tax reporting
purposes of approximately $13,076,000 which expire through July 31, 2021. The
valuation allowance related to the Company's NOLs was reversed in connection
with the purchase price allocation for the Minntech acquisition, based upon an
assessment of the combined companies expected future results of operations.

          In addition, the Company and its foreign subsidiaries cannot file
consolidated tax returns for United States income tax purposes. Therefore, the
Company's NOLs in the United States cannot be utilized to reduce federal or
provincial income taxes payable by the foreign subsidiaries on their taxable
income. This has resulted in the payment of income taxes by the Company in
Canada and the Netherlands, notwithstanding NOLs utilized, or net losses
sustained, by the Company in the United States.

          Inflation has not significantly impacted the Company's operations.

CRITICAL ACCOUNTING POLICIES

          The Company's discussion and analysis of its financial condition and
results of operations are based upon the Company's consolidated financial
statements, which have been prepared in accordance with accounting principles
generally accepted in the United States. The preparation of these financial
statements requires the Company to make estimates and judgments that affect the
reported amounts of assets, liabilities, revenues and expenses, and related
disclosure of contingent assets and liabilities. On an ongoing basis, the
Company continually evaluates its estimates. The Company bases its estimates on
historical experience and on various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that

                                     - 39 -
<Page>

are not readily apparent from other sources. Actual results may differ from
these estimates.

          The Company believes the following critical accounting policies affect
its more significant judgments and estimates used in the preparation of its
consolidated financial statements.

     REVENUE RECOGNITION

          Revenue on product sales is recognized as products are shipped to
customers or when title passes, net of provisions for sales allowances and
similar items. Domestic sales of endoscope reprocessing equipment are of a bill
and hold nature as more fully described in note 11 to the Consolidated Financial
Statements. Revenue on service sales is recognized when repairs are completed
and the products are shipped to customers.

     ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS

          Accounts receivable consist of amounts due to the Company from normal
business activities. Allowances for doubtful accounts are reserves for the
estimated loss from the inability of customers to make required payments. The
Company uses historical experience as well as current market information in
determining the estimate. If the financial condition of the Company's customers
were to deteriorate, resulting in an impairment of their ability to make
payments, additional allowances may be required.

     INVENTORIES

          Inventories consist of products which are sold in the ordinary course
of the Company's business and are stated at the lower of cost (first-in,
first-out) or market. In assessing the value of inventories, the Company must
make estimates and judgments regarding reserves required for product
obsolescence, aging of inventories and other issues potentially affecting the
saleable condition of products. In performing such evaluations, the Company uses
historical experience as well as current market information.

     DEFERRED TAX ASSETS AND LIABILITIES

          The Company recognizes deferred tax assets and liabilities based on
the differences between the financial statement carrying amounts and the tax
bases of assets and liabilities. Deferred tax assets and liabilities also
include items recorded in conjunction with the purchase accounting for business
acquisitions. The Company regularly reviews its deferred tax assets for
recoverability and establishes a valuation allowance based on historical taxable
income, projected future taxable income, and the expected timing of the
reversals of existing

                                     - 40 -
<Page>

temporary differences. Although realization is not assured, management believes
it is more likely than not that the recorded deferred tax assets will be
realized. Additionally, deferred tax liabilities are regularly reviewed to
confirm that the amounts recorded are appropriately stated. All of such
evaluations require significant management judgments.

     LONG-LIVED ASSETS

          Certain of the Company's identifiable intangible assets, such as
current technology and customer base, are amortized on the straight-line method
over their estimated useful lives. Additionally, the Company has recorded
goodwill and trademarks and tradenames, all of which have indefinite useful
lives and are therefore not amortized. These assets are reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable, and goodwill is reviewed for impairment at
least annually in accordance with Statement of Financial Accounting Standard No.
142, "GOODWILL AND OTHER INTANGIBLE ASSETS."

     BUSINESS COMBINATIONS

          During fiscal 2002, the Company's acquisition of Minntech required
significant estimates and judgments related to the fair value of assets acquired
and liabilities assumed. Certain of the liabilities are subjective in nature.
These liabilities have been reflected in the purchase accounting based upon the
most recent information available, and principally include certain state sales
and use tax and state income tax exposures, as well as income tax liabilities
related to the Company's foreign subsidiaries. The ultimate settlement of such
liabilities may be for amounts which are different from the amounts presently
recorded.

     OTHER MATTERS

          The Company does not have any off balance sheet financial
arrangements.

FORWARD LOOKING STATEMENTS

          Management's Discussion and Analysis of Financial Condition and
Results of Operations contains forward-looking statements. All forward-looking
statements involve risks and uncertainties, including, without limitation,
acceptance and demand of new products, the impact of competitive products and
pricing, the Company's ability to successfully integrate and operate acquired
and merged businesses and the risks associated with such businesses, and the
risks detailed in the Company's filings and reports with the Securities and
Exchange Commission. Such

                                     - 41 -
<Page>

statements are only predictions, and actual events or results may differ
materially from those projected.

ITEM 7A.  QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK.

          Foreign currency market risk: A portion of the Company's products are
imported from the Far East and Western Europe, the Company's United States
subsidiaries sell a portion of their products outside of the United States, and
Minntech's Netherlands subsidiary sells a portion of its products outside of the
European Union. Consequently, the Company's business could be materially and
adversely affected by the imposition of trade barriers, fluctuations in the
rates of exchange of various currencies, tariff increases and import and export
restrictions, affecting the United States, Canada and the Netherlands.

          Carsen imports a substantial portion of its products from the United
States and pays for such products in United States dollars, and Carsen's
business could be materially and adversely affected by the imposition of trade
barriers, fluctuations in the rates of currency exchange, tariff increases and
import and export restrictions between the United States and Canada.
Additionally, Carsen's financial statements are translated using the accounting
policies described in Note 2 to the Consolidated Financial Statements.
Fluctuations in the rates of currency exchange between the United States and
Canada had an adverse impact in fiscal 2002 compared with fiscal 2001, and in
fiscal 2001 compared with fiscal 2000, upon the Company's results of operations
and stockholders' equity, as described in Management Discussion and Analysis of
Financial Condition and Results of Operations.

          Financial statements of the Netherlands subsidiary are translated
using the accounting policies described in Note 2 to the Consolidated Financial
Statements. Fluctuations in the rates of currency exchange between the European
Union and the United States had an adverse impact in fiscal 2002 upon the
Company's results of operations, as described in Management's Discussion and
Analysis of Financial Condition and Results of Operations.

          The functional currency of Minntech's Japan subsidiary is the Japanese
yen. Changes in the value of the Japanese yen relative to the United States
dollar since the acquisition of Minntech on September 7, 2001 did not have a
significant impact upon either the Company's results of operations or the
translation of the balance sheet, primarily due to the fact that the Company's
Japanese subsidiary accounts for a relatively small portion of consolidated net
sales, earnings and net assets.

          Interest rate market risk: The Company has two credit

                                     - 42 -
<Page>

facilities for which the interest rate on outstanding borrowings is variable.
Therefore, interest expense is principally affected by the general level of
interest rates in the United States and Canada. During fiscal 2002, all of the
Company's outstanding borrowings were under its United States credit facilities.
In order to protect its interest rate exposure, the Company has entered into a
three-year interest rate cap expiring on September 7, 2004 covering $12,500,000
of borrowings under the Term Loan Facility, which caps LIBOR on this portion of
outstanding borrowings at 4.50%. At July 31, 2002, the fair value of such
interest rate cap is $52,000.

ITEM 8.   FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

          See Index to Consolidated Financial Statements, which is Item 14(a),
and the Consolidated Financial Statements and schedule attached to this Report.

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

          The Company has not had any disagreements with its accountants on
accounting or financial disclosure.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Cantel Medical Corp.

We have audited the accompanying consolidated balance sheets of Cantel Medical
Corp. as of July 31, 2002 and 2001 and the related consolidated statements of
income, changes in stockholders' equity and cash flows for each of the three
years in the period ended July 31, 2002. Our audits also included the financial
statement schedule listed in the Index at Item 14(a). These financial statements
and schedule are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements and
schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Cantel
Medical Corp. at July 31, 2002 and 2001 and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
July 31, 2002, in conformity with accounting principles generally accepted in
the United States. Also, in our opinion, the related financial statement
schedule, when considered in relation to the basic financial statements taken as
a whole, presents fairly in all material respects the information set forth
therein.

                              CANTEL MEDICAL CORP.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                    YEARS ENDED JULY 31, 2002, 2001 AND 2000

1.   BUSINESS DESCRIPTION

Cantel Medical Corp. ("Cantel") had three wholly-owned operating subsidiaries
(collectively known as the "Company") at July 31, 2002.

On September 7, 2001, the Company completed its acquisition of Minntech
Corporation ("Minntech"), as more fully described in note 3 to the Consolidated
Financial Statements. Minntech designs, develops, manufactures, markets and
distributes disinfection/sterilization reprocessing systems, sterilants and
other supplies for renal dialysis as well as filtration and separation and other
products for medical and non-medical applications. The products are available
through Minntech's distribution network in the United States and in many
international markets.

MediVators, Inc. ("MediVators") designs, develops, manufactures, markets and
distributes endoscope reprocessing products. Minntech and MediVators are
sometimes collectively referred to as the "United States subsidiaries." Carsen
Group Inc. ("Carsen" or "Canadian subsidiary") is engaged in the marketing,
distribution and service of endoscopy and surgical, endoscope reprocessing and
scientific products in Canada.

Effective July 31, 2000, Carsen discontinued its Consumer Products business and
the results of Consumer Products have been presented as a discontinued
operation, as described in note 8 to the Consolidated Financial Statements.

In May 2002, the Company issued 3,143,000 additional shares in connection with a
three-for-two stock split effected in the form of a 50% stock dividend paid on
May 14, 2002 to stockholders of record on May 7, 2002. The effect of the stock
split has been recognized retroactively in the stockholders' equity accounts in
the Consolidated Balance Sheets and Consolidated Statements of Changes in
Stockholders' Equity, and all share data in the Consolidated Statements of
Income, Notes to Consolidated Financial Statements, and Management's Discussion
and Analysis of Financial Condition and Results of Operations.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Cantel Medical
Corp. and its wholly-owned subsidiaries. All intercompany transactions and
balances have been eliminated in consolidation.

REVENUE RECOGNITION

Revenue on product sales is recognized as products are shipped to customers or
when title passes, net of provisions for sales allowances and similar items.
Domestic sales of endoscope reprocessing equipment are of a bill and hold nature
as more fully described in note 11 to the Consolidated Financial Statements.
Revenue on service sales is recognized when repairs are completed and the
products are shipped to customers.

TRANSLATION OF FOREIGN CURRENCY FINANCIAL STATEMENTS

Assets and liabilities of the Company's foreign subsidiaries are translated into
United States dollars at year-end exchange rates; sales and expenses are
translated using average exchange rates during the year. The cumulative effect
of the translation of the accounts of the foreign subsidiaries is presented as a
component of accumulated other comprehensive loss. Foreign exchange gains and
losses related to the purchase of inventories are included in cost of sales.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with maturities of three
months or less when purchased to be cash equivalents.

AVAILABLE-FOR-SALE SECURITIES

Available-for-sale securities are carried at fair value, with the unrealized
gain reported as a component of accumulated other comprehensive loss. Securities
at July 31, 2001 consisted exclusively of Minntech common stock purchased for
$725,000 during September 2000. The unrealized gain on such securities during
fiscal 2001 was $332,000 and was eliminated during fiscal 2002 as a result of
the Minntech acquisition. The elimination of this unrealized gain had no impact
upon the Company's results of operations.

                                        7

INVENTORIES

Inventories are stated at the lower of cost (first-in, first-out) or market.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Additions and improvements are
capitalized, while maintenance and repair costs are expensed. When assets are
retired or otherwise disposed of, the cost and related accumulated depreciation
or amortization is removed from the respective accounts and any resulting gain
or loss is included in income. Depreciation and amortization is provided on
either the straight-line method or, for certain furniture and equipment, the
declining balance method, over the estimated useful lives of the assets which
generally range from 3-10 years for furniture and equipment, 5-32 years for
buildings and improvements and the life of the lease for leasehold improvements.
Depreciation and amortization expense related to property and equipment for
fiscal 2002, 2001 and 2000 was $2,654,000, $410,000 and $402,000, respectively.

INTANGIBLE ASSETS

In June 2001, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards ("SFAS") No. 141, "BUSINESS COMBINATIONS"
("SFAS 141") and SFAS No. 142, "GOODWILL AND OTHER INTANGIBLE ASSETS" ("SFAS
142"). SFAS 141 requires all business combinations initiated after June 30, 2001
to be accounted for using the purchase method. Under SFAS 142, goodwill and
intangible assets with indefinite lives are no longer amortized but are reviewed
annually (or more frequently if impairment indicators arise) for impairment.
Separable intangible assets that are not deemed to have indefinite lives will
continue to be amortized over their useful lives (but with no maximum life).
Upon adoption of SFAS 142, amortization of goodwill recorded for business
combinations consummated prior to July 1, 2001 will cease, and intangible assets
acquired prior to July 1, 2001 that do not meet the criteria for recognition
under SFAS 141 will be reclassified to goodwill. The amortization provisions of
SFAS 142 apply to goodwill and intangible assets acquired after June 30, 2001.
Companies are required to adopt SFAS 142 for fiscal years beginning after
December 15, 2001, but early adoption is permitted. The Company adopted SFAS 142
on August 1, 2001, which was the beginning of fiscal 2002.

Pursuant to SFAS 142, the Company performed a benchmark goodwill impairment
assessment for the goodwill arising from the Minntech acquisition, as more fully
described in note 3 to the Consolidated

                                        8
<Page>

Financial Statements. Goodwill amortization amounted to $35,000 during each of
fiscal 2001 and 2000.

Intangible assets with finite lives, including technology, customer lists,
patents and non-compete agreements, are stated at cost and amortized on a
straight-line basis over their estimated useful lives of 2 to 20 years.

OTHER ASSETS

Debt issuance costs associated with the credit facilities for the Minntech
merger are amortized to interest expense over the five-year life of the credit
facilities, except for debt issuance costs related to an interest rate cap which
are amortized over a three-year period, as more fully described in notes 6 and 9
to the Consolidated Financial Statements. As of July 31, 2002 and 2001, such
debt issuance costs, net of related amortization, are included in other assets
and amounted to $1,384,000 and $455,000, respectively. Additionally, other
assets at July 31, 2001 included $1,828,000 of professional fees related to the
Minntech acquisition; such amount was reclassified in conjunction with the
purchase accounting.

Inventories of sales samples which have not turned over within one year and
medical loaners available for customers are also included in other assets and
are carried at the lower of cost or net realizable value.

LONG-LIVED ASSETS

The Company assesses potential impairments to its long-lived assets periodically
in accordance with the provisions of SFAS No. 121, "ACCOUNTING FOR THE
IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF"
("SFAS 121"). Long-lived assets are evaluated for impairment when events or
changes in circumstances indicate that the carrying amount of the assets may not
be recoverable through the estimated undiscounted future cash flows resulting
from the use of these assets. When any such impairment exists, the related
assets will be written down to fair value.

In August 2001, the FASB issued SFAS No. 144, "ACCOUNTING FOR THE IMPAIRMENT OR
DISPOSAL OF LONG-LIVED ASSETS" ("SFAS 144"), which establishes financial
accounting and reporting for the impairment or disposal of long-lived assets and
supersedes SFAS 121. SFAS 144 addresses the accounting for a segment of a
business accounted for as a discontinued operation which was not previously
addressed by SFAS 121. In addition, SFAS 144 resolves significant implementation
issues related to SFAS 121. The provisions of SFAS 144 are effective for fiscal
years beginning after December 15,

                                        9
<Page>

2001.  The Company believes that the adoption of SFAS 144 will have no
significant impact on its financial reporting and related disclosures.

STOCK-BASED COMPENSATION

As permitted by SFAS No. 123, "ACCOUNTING FOR STOCK-BASED COMPENSATION" ("SFAS
123"), the Company has elected to follow Accounting Principal Board Opinion No.
25, "ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES" ("APB 25") and related
interpretations in accounting for its stock option plans. Under APB 25, no
compensation expense is recognized at the time of option grant if the exercise
price of the Company's employee stock option is fixed and equals or exceeds the
fair market value of the underlying common stock on the date of grant.

ADVERTISING COSTS

The Company's policy is to expense advertising costs as they are incurred.
Advertising costs charged to expenses were $146,000, $26,000 and $13,000 for
fiscal 2002, 2001 and 2000, respectively.

INCOME TAXES

The Company accounts for income taxes by the liability method in accordance with
SFAS No. 109 "ACCOUNTING FOR INCOME TAXES" ("SFAS 109"). SFAS 109 requires the
recognition of deferred tax liabilities and assets for the expected future tax
consequences of temporary differences between the financial statement carrying
amounts and the tax basis of assets and liabilities.

Approximately $5,112,000 of the undistributed earnings of the Company's foreign
subsidiaries was considered to be indefinitely reinvested at July 31, 2002.
Accordingly, no provision has been recorded for U.S. income taxes that might
result from repatriation.

EARNINGS PER COMMON SHARE

Basic earnings per common share are computed based upon the weighted average
number of common shares outstanding during the year.

Diluted earnings per common share are computed based upon the weighted average
number of common shares outstanding during the year plus the dilutive effect of
options using the treasury stock method and the average market price for the
year.

As described in note 1 to the Consolidated Financial Statements, the
calculations of weighted average common shares and earnings per share for all
periods presented reflect the May 2002 stock split.

                                       10
<Page>

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

RECLASSIFICATIONS

Certain items in the July 31, 2001 and 2000 financial statements have been
reclassified from amounts previously reported to conform to the presentation of
the July 31, 2002 financial statements. These reclassifications include the
reporting of warehouse and shipping expenses in cost of sales, and the operating
segment classification of sales of MediVators parts from Endoscope Reprocessing
Products to Product Service.

NEW ACCOUNTING PRONOUNCEMENT

In June 2002, the FASB issued SFAS No. 146, "ACCOUNTING FOR COSTS ASSOCIATED
WITH EXIT OF DISPOSAL Activities" ("SFAS 146"). This Statement addresses
financial accounting and reporting for costs associated with exit or disposal
activities and nullifies Emerging Issues Task Force ("EITF") Issue No. 94-3,
"LIABILITY RECOGNITION FOR CERTAIN EMPLOYEE TERMINATION BENEFITS AND OTHER COSTS
TO EXIT AN ACTIVITY (INCLUDING CERTAIN COSTS INCURRED IN A RESTRUCTURING)."
Under SFAS 146 companies recognize a cost associated with an exit or disposal
activity when a liability has been incurred, while under EITF Issue No. 94-3
companies recognized costs once management implemented a plan to exit an
activity. SFAS 146 also introduces discounting the liability associated with the
exit or disposal activity for the time between the cost being incurred and when
the liability is ultimately settled. SFAS 146 would not have had a material
impact on the Company's fiscal 2002 financial position or results of operations.

3.   ACQUISITIONS

     MINNTECH

On September 7, 2001, the Company completed its acquisition of Minntech, a
public company based in Plymouth, Minnesota, in a merger transaction. Minntech
is a leader in the development, manufacturing, and marketing of
disinfection/sterilization reprocessing systems and sterilants for renal
dialysis as well as filtration and separation and other products for medical and
non-medical applications. The products are available through

                                       11
<Page>

Minntech's distribution network in the United States and in many international
markets.

Under the terms of the Agreement and Plan of Merger, each share of Minntech was
converted into the right to receive $10.50, consisting of $6.25 in cash, and a
fraction of a share of Cantel common stock having a value of $4.25. With respect
to the stock portion of the consideration, Cantel issued approximately 2,201,000
shares of common stock in the merger. The total consideration for the
transaction, including transaction costs, was approximately $78,061,000 (as
adjusted for fractional shares, and included cash of $41,396,000, shares of
Cantel common stock with a fair market value of $28,144,000, Cantel's existing
investment in Minntech of $725,000 and final transaction costs, including
severance obligations, of approximately $7,796,000). The transaction was
accounted for as a purchase and in accordance with the provisions of SFAS 141.
Minntech is reflected in the Company's results of operations for the portion of
fiscal 2002 subsequent to its acquisition on September 7, 2001, and is not
reflected in the results of operations for fiscal 2001 and 2000.

In conjunction with the acquisition, on September 7, 2001 Cantel entered into
new credit facilities to fund the financed portion of the cash consideration
paid in the merger and costs associated with the merger, as well as to replace
the Company's existing working capital credit facilities, as discussed in note 9
to the Consolidated Financial Statements.

The purchase price was allocated to the assets acquired and assumed liabilities
as follows: cash and cash equivalents $17,395,000; accounts receivable
$12,342,000; inventories $10,205,000; prepaids and other current assets
$7,026,000; property and equipment $22,932,000; intangible assets $7,705,000;
other noncurrent assets $594,000; current liabilities $11,143,000; noncurrent
deferred income tax liabilities $6,430,000; and other long-term liabilities
$1,766,000. Intangible assets acquired of $7,705,000 included the following:
current technology $4,459,000 (14 year life), customer base $1,952,000 (7 year
life), trademarks and tradenames $1,015,000 (indefinite life) and
covenant-not-to-compete $279,000 (2 year life). The weighted average life of
these intangible assets (excluding such assets with an indefinite life) was
approximately 11.5 years. There were no in-process research and development
projects acquired in connection with the acquisition. Additionally, in
conjunction with the purchase price accounting, Cantel reversed the valuation
allowance associated with its deferred tax assets originating from net operating
loss carryforwards ("NOLs"), resulting in $3,583,000 of net deferred tax assets.
The excess purchase price of $15,618,000 was assigned to goodwill.

                                       12
<Page>

During July 2002, goodwill was increased from its preliminary allocation by
$1,009,000, due primarily to increases in liabilities for state sales and use
taxes and state income taxes, partially offset by an increase in deferred tax
assets relating to NOLs. Such goodwill, all of which is non-deductible for
income tax purposes, was allocated to the Company's operating segments as
follows: Dialysis Products $9,074,000, Filtration and Separation Products
$2,655,000 and Endoscope Reprocessing Products $3,889,000.

Certain of the assumed liabilities are subjective in nature. These liabilities
have been reflected based upon the most recent information available, and
principally include certain state sales and use tax and state income tax
exposures and income tax liabilities related to the Company's foreign
subsidiaries. The ultimate settlement of such liabilities may be for amounts
which are different from the amounts presently recorded.

Selected unaudited pro forma consolidated statements of income data assuming
that Minntech was included in the Company's results of operations as of the
beginning of the years ended July 31, 2002 and 2001 is as follows:

       Diluted                                   9,937,000         9,566,000
</Table>

This pro forma information is provided for illustrative purposes only, and does
not necessarily indicate what the operating results of the combined company
might have been had the merger actually occurred at the beginning of each of
these periods, nor does it necessarily indicate the combined company's future
operating results. This information also does not reflect any cost savings from
operating efficiencies or other improvements which may be achieved by combining
the companies.

The results presented in the selected unaudited pro forma consolidated
statements of income data have been prepared using the following assumptions:
(i) cost of sales reflects a step-up in the

                                       13
<Page>

cost basis of Minntech's inventories; (ii) amortization of intangible assets
and depreciation and amortization of property and equipment is based upon the
final appraised fair values and estimated useful lives of such assets; (iii)
in accordance with the provisions of SFAS 142, no amortization expense for
the goodwill generated as a result of the merger has been reflected; (iv)
interest expense on the senior bank debt at an effective interest rate of 7%
per annum; and (v) calculation of the income tax effects of the pro forma
adjustments.

Minntech's results of operations for the twelve months ended July 31, 2001
included charges of approximately $1,540,000 for sales and use taxes and
$300,000 in legal and cosulting expenses associated with the merger. Without
these charges and the related income taxes, pro forma consolidated income
from continuing operations for fiscal 2001 would have been approxiamtely
$6,345,000, and pro forma consolidated basic and diluted earnings per share
would have been $0.71 and $0.66, respectively.

     TECHNIMED

On November 1, 2001, the Company's Canadian subsidiary acquired substantially
all of the assets, business and properties of Technimed Instruments Inc. and
Technimed International Inc. (collectively "Technimed") for approximately
$405,000, which included cash of approximately $241,000 and a note payable in
three equal annual installments with a present value of approximately $164,000.
This transaction was accounted for as a purchase and in accordance with the
provisions of SFAS 141.

The purchase price was allocated to the assets acquired and assumed liabilities
as follows: current assets $148,000; property and equipment $30,000; intangible
assets $172,000; current liabilities $105,000; and long-term liabilities
$12,000. The excess purchase price of $172,000 was assigned to goodwill. The
acquisition and subsequent results of Technimed did not have a significant
impact upon the Company's results of operations for fiscal 2002.

Technimed was a private company based in Montreal, Canada servicing medical
equipment, including rigid endoscopes and hand-held surgical instrumentation.

4.   COMPREHENSIVE INCOME

                                       14

At July 31, 2001, the Company had an unrealized gain on securities of $332,000
which was eliminated during fiscal 2002 in connection with the Minntech
acquisition purchase accounting. The elimination of this unrealized gain had no
impact upon the Company's results of operations.

6.   FINANCIAL INSTRUMENTS

Effective August 1, 2000, the Company adopted SFAS No. 133, as amended,
"ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES" ("SFAS 133").
Because of the Company's minimal use of hedging activities, the adoption of this
statement did not have a significant effect on the financial position or results
of operations of the Company. SFAS 133 requires the Company to recognize all
derivatives on the balance sheet at fair value. Derivatives that are not
designated as hedges must be adjusted to fair value through earnings. If the
derivative is designated as a hedge, depending on the nature of the hedge,
changes in the fair value of the derivatives will either be offset against the
change in the fair value of the hedged assets, liabilities or firm commitments
through earnings or recognized in other comprehensive income until the hedged
item is recognized in earnings. The ineffective portion of the change in fair
value of a derivative that is designated as a hedge will be immediately
recognized in earnings. The adoption of SFAS 133 on August 1, 2000 did not have
a material impact on operations; however, it resulted in a $107,000 gain being
recorded in other comprehensive income. During fiscal 2001, this entire gain of
$107,000 was included in income.

The Company's Canadian subsidiary purchases and pays for a substantial portion
of its products in United States dollars and is therefore exposed to
fluctuations in the rates of exchange between the United States dollar and
Canadian dollar. In order to hedge against the impact of such currency
fluctuations on the purchases of inventories, Carsen enters into foreign
currency forward contracts on firm purchases of such inventories in United
States dollars. Total commitments for such foreign currency forward contracts

                                       15
<Page>

amounted to $9,800,000 (United States dollars) at July 31, 2002 and cover a
portion of Carsen's projected purchases of inventories through February 2003.

In addition, changes in the value of the euro against the United States dollar
affect the Company's results of operations because a portion of the net assets
of Minntech's Netherlands subsidiary are denominated and ultimately settled in
United States dollars but must be converted into its functional euro currency.
In order to hedge against the impact of fluctuations in the value of the euro
relative to the United States dollar, the Company enters into short-term
contracts to purchase euros forward. There was one such foreign currency forward
contract amounting to (euro)4,500,000 at July 31, 2002 which covers a portion of
the net assets of Minntech's Netherlands subsidiary which are denominated in
United States dollars. Such contract expired on August 31, 2002. Under its
credit facilities, such contracts to purchase euros may not exceed $12,000,000
in an aggregate notional amount at any time.

In accordance with SFAS 133, all of the Company's foreign currency forward
contracts are designated as hedges. Recognition of gains and losses related to
the Canadian hedges is deferred within other comprehensive income until
settlement of the underlying commitments, and realized gains and losses are
recorded within cost of sales upon settlement. Gains and losses related to the
hedging contracts to buy euros forward is immediately realized within general
and administrative expenses due to the short-term nature of such contracts. The
Company does not hold any derivative financial instruments for speculative or
trading purposes.

The Company entered into new credit facilities in September 2001, as more fully
described in note 9, for which the interest rate on outstanding borrowings is
variable. In order to protect its interest rate exposure, the Company entered
into a three-year interest rate cap agreement expiring on September 7, 2004
which caps the London Interbank Offered Rate ("LIBOR") at 4.50% on $12,500,000
of the Company's borrowings. The cost of the interest rate cap, which is
included in other assets, was $246,500 and is being amortized to interest
expense over the three-year life of the agreement. The difference between its
amortized cost and its fair value is recorded as an unrealized loss at July 31,
2002 and is included in other comprehensive income.

                                       16

The fair value of the Company's interest rate cap agreement and Carsen's foreign
currency forward contracts is based upon quoted market prices as provided by
financial institutions which are counterparties to the agreements and is as
follows:

</Table>

As of July 31, 2002 and 2001, the carrying amounts for cash and cash
equivalents, accounts receivable and accounts payable approximate fair value due
to the short maturity of these instruments. The Company believes that as of July
31, 2002, the fair value of its long-term debt approximates the carrying value
of those obligations based on the borrowing rates which are comparable to market
interest rates.

7.   INTANGIBLES AND GOODWILL

The Company's intangible assets which continue to be subject to amortization
consist primarily of technology, customer lists, non-compete agreements and
patents. These intangible assets are being amortized on the straight-line method
over the estimated useful lives of the assets ranging from 2-20 years and have a
weighted average amortization period of 11 years as of July 31, 2002.
Amortization expense related to intangible assets was $780,000, $143,000 and
$148,000 for fiscal 2002, 2001 and 2000, respectively. Intangible assets
acquired in conjunction with the Minntech acquisition are more fully described
in note 3 to the Consolidated Financial Statements. The Company's intangible
assets that have indefinite useful lives and therefore are not amortized consist
of trademarks and tradenames.

The Company's intangible assets consist of the following:

                 2007           718,000
</Table>

For fiscal 2002, goodwill increased by $15,791,000 primarily due to the
acquisition of Minntech as more fully described in note 3 to the Consolidated
Financial Statements. At the time of the Minntech acquisition a goodwill
benchmark impairment study was performed. On August 1, 2002, such goodwill was
reviewed for impairment by an independent appraiser using the methods prescribed
in SFAS 142. Based upon such review, the Company concluded that there was no
impairment of the goodwill.

8.   DISCONTINUED OPERATIONS

On October 6, 2000, Carsen closed a transaction under an Asset Purchase
Agreement (the "Purchase Agreement") with Olympus America Inc. ("Olympus")
pursuant to which Carsen terminated its consumer products business and sold its
inventories of Olympus consumer products to Olympus. The transaction had an
effective date of July 31, 2000.

The purchase price for the inventory was $1,026,000, net of adjustments related
to estimated warranty claims and promotional program expenses payable to
Carsen's customers. During fiscal 2001, Carsen also received additional
consideration from Olympus under the Purchase Agreement, including amounts
related to transition services provided by Carsen subsequent to July 31, 2000.
Such consideration included (i) fixed cash amounts aggregating approximately
$615,000 and (ii) $619,000, representing twelve and one-half percent (12 1/2%)
of Olympus' net sales of consumer products in Canada in excess of $8,000,000
during the period from August 1, 2000 through March 31, 2001. No additional
amounts are due from Olympus under the Purchase Agreement.

The discontinuance of the Consumer Products business has been reflected as a
discontinued operation and is presented separately in the Company's Consolidated
Financial Statements.

At July 31, 2002 and 2001, remaining liabilities of the discontinued business
were $34,000 and $96,000, respectively, and are included within accrued
expenses.

9.   FINANCING ARRANGEMENTS

At July 31, 2001, the Company had a credit facility which provided for (i) a
$2,500,000 revolving credit facility for Cantel and MediVators, (ii) a
$5,000,000 (United States dollars) revolving credit facility for Carsen, and
(iii) a $12,500,000 acquisition facility available to Cantel and MediVators for
permitted acquisitions in the United States. At July 31, 2001, the Company had
no outstanding borrowings under this credit facility.

In conjunction with the acquisition of Minntech on September 7, 2001, the
Company entered into new credit facilities to fund the financed portion of the
cash consideration paid in the merger and costs associated with the merger, as
well as to replace the Company's existing working capital credit facilities. The
new credit facilities include (i) a $25,000,000 senior secured amortizing term
loan facility from a consortium of U.S. lenders (the "Term Loan Facility") used
by Cantel to finance a portion of the Minntech acquisition, (ii) a $17,500,000
senior secured revolving credit facility from the U.S. lenders (the "U.S.
Revolving Credit Facility") used by Cantel to finance a portion of the Minntech
acquisition as well as being available for future working capital requirements
for the U.S. businesses of Cantel, including Minntech and MediVators (the "U.S.
Borrowers") and (iii) a $5,000,000 (United States dollars) senior secured
revolving credit facility for Carsen (the "Canadian Borrower") with a Canadian
bank (the "Canadian Revolving Credit Facility") available for Carsen's future
working capital requirements. Each of the Term

                                       19
<Page>

Loan Facility, the U.S. Revolving Credit Facility and the Canadian Revolving
Credit Facility (collectively the "Credit Facilities") expire on September 7,
2006.

Borrowings under the Credit Facilities bear interest at rates ranging from .75%
to 2.00% above the lender's base rate, or at rates ranging from 2.00% to 3.25%
above LIBOR, depending upon the Company's consolidated ratio of debt to earnings
before interest, taxes, depreciation and amortization ("EBITDA"). The base rates
associated with the U.S. lenders and the Canadian lender were 4.75% and 4.50%,
respectively, at July 31, 2002, and the LIBOR rates ranged from 1.81% to 1.83%
at July 31, 2002. The margins applicable to the Company's outstanding borrowings
at July 31, 2002 are 1.5% above the lender's base rate and 2.75% above LIBOR. In
order to protect its interest rate exposure, the Company entered into a
three-year interest rate cap agreement expiring on September 7, 2004 covering
$12,500,000 of borrowings under the Term Loan Facility, which caps LIBOR on this
portion of outstanding borrowings at 4.50%. The Credit Facilities also provide
for fees on the unused portion of such facilities at rates ranging from .30% to
..50%, depending upon the Company's consolidated ratio of debt to EBITDA.

The Term Loan Facility and the U.S. Revolving Credit Facility provide for
available borrowings based upon percentages of the U.S. Borrowers' eligible
accounts receivable and inventories; require the U.S. Borrowers to meet certain
financial covenants; are secured by substantially all assets of the U.S.
Borrowers (including a pledge of the stock of Minntech and MediVators owned by
Cantel and 65% of the outstanding shares of Carsen stock owned by Cantel); and
are guaranteed by Minntech and MediVators. The Canadian Revolving Credit
Facility provides for available borrowings based upon percentages of the
Canadian Borrower's eligible accounts receivable and inventories; requires the
Canadian Borrower to meet certain financial covenants; and is secured by
substantially all assets of the Canadian Borrower.

On September 7, 2001, the Company borrowed $25,000,000 under the Term Loan
Facility and $9,000,000 under the U.S. Revolving Credit Facility in connection
with the acquisition of Minntech. At July 31, 2002, the Company had $28,500,000
outstanding under its Credit Facilities, including $23,500,000 under the Term
Loan Facility. Amounts repaid by the Company under the Term Loan Facility may
not be re-borrowed.

Although deferred tax assets and liabilities have been adjusted for enacted
changes in statutory tax rates, these adjustments were not significant since the
Company's items of deferred tax are substantially in the United States where
statutory tax rates are

                                       22
<Page>

unchanged. Such deferred tax items in the United States are reflected at a
combined U.S. federal and state effective rate of 40%.

At July 31, 2001, the Company had deferred tax assets related to NOLs and
cumulative temporary differences of $5,032,000 which was fully offset by a
valuation allowance since the Company was not assured at that time that it was
more likely than not that a benefit would be realized. However, the valuation
allowance related to the Company's NOLs and cumulative temporary differences was
eliminated in connection with the purchase accounting for the Minntech
acquisition based upon an assessment of the combined companies expected future
results of operations.

For domestic tax reporting purposes, the Company has NOLs of approximately
$13,076,000 at July 31, 2002, which expire through July 31, 2021. The NOLs
presented are based upon the tax returns as filed and are subject to examination
by the Internal Revenue Service.

Approximately $5,112,000 of the undistributed earnings of the Company's foreign
subsidiaries was considered to be indefinitely reinvested at July 31, 2002.
Accordingly, no provision has been recorded for U.S. income taxes that might
result from repatriation.

11.  COMMITMENTS AND CONTINGENCIES

DISTRIBUTION AGREEMENTS

     OLYMPUS/CARSEN AGREEMENT

The majority of Carsen's sales of endoscopy and surgical products and scientific
products related to precision instruments have been made pursuant to an
agreement with Olympus America Inc. (the "Olympus Agreement"), and the majority
of Carsen's sales of scientific products related to industrial technology
equipment have been made pursuant to an agreement with Olympus Industrial
America Inc. (the "Olympus Industrial Agreement") (collectively the "Olympus
Agreements"), under which Olympus has granted Carsen the exclusive right to
distribute the covered Olympus products in Canada. All products sold by Carsen
pursuant to the agreements bear the trademark of Olympus or its affiliates. Both
Olympus agreements expire on March 31, 2004. If Carsen fulfills its obligations
under the Olympus Agreement, the parties will establish new minimum purchase
requirements and extend the Olympus Agreement through March 31, 2006. There are
no minimum purchase requirements under the Olympus Industrial Agreement.

During the term of the Olympus Agreements and for one year thereafter, Carsen
has agreed that it will not manufacture,

                                       23
<Page>

distribute, sell or represent for sale in Canada any products which are
competitive with the Olympus products covered by the Olympus Agreements.

The Olympus Agreement imposes minimum purchase obligations on Carsen with
respect to each of endoscopy and surgical products and precision instruments.
The aggregate annual minimum purchase obligations for all such products are
approximately $16.9 million and $18.8 million during the contract years ending
March 31, 2003 and 2004, respectively.

The Olympus Agreements generally prohibit both Olympus and Carsen from hiring
any employee of the other party for a period of one year after the conclusion of
the employee's employment with such other party. This prohibition remains in
effect during the term of the Olympus Agreements and the first year thereafter.

Subject to an allowance of a 10% shortfall from the minimum purchase
requirements, if Carsen fails to meet such requirements for precision
instruments, then Olympus has the option to terminate or restructure the Olympus
Agreement as it pertains to precision instruments; if Carsen fails to meet such
requirements for endoscopy and surgical products, then Olympus has the option to
terminate or restructure the entire Olympus Agreement. Olympus may also
terminate the Olympus Agreement if Carsen breaches its other obligations under
the Olympus Agreement.

     MEDIVATORS/OLYMPUS AGREEMENT

MediVators has a four-year agreement with Olympus America Inc., which expires on
August 1, 2003, under which Olympus is granted the exclusive right to distribute
all of MediVators' endoscope reprocessing products and related accessories and
supplies in the United States and Puerto Rico (the "MediVators Agreement").
MediVators also has a three-year agreement with Olympus Latin America which
expires on July 21, 2005 under which Olympus is granted the exclusive right to
distribute all of MediVators endoscope reprocessing products and related
accessories and supplies in Latin America; to date such agreement has not
produced significant levels of sales in Latin America. All equipment sold by
Olympus pursuant to these agreements bear both the "Olympus" and "MediVators"
trademarks.

The MediVators Agreement provides for minimum purchase projections. Failure by
Olympus to achieve the minimum purchase projections in any contract year gives
MediVators the option to terminate the MediVators Agreement. Net sales to
Olympus accounted for 9.5%, 18.4%, and 15.8% of the Company's net sales in
fiscal 2002, 2001 and 2000, respectively.

                                       24
<Page>

Sales to Olympus of endoscope disinfection equipment are recognized on a bill
and hold basis based upon the receipt of a written purchase order from Olympus,
the completion date specified in the order, the actual completion of the
manufacturing process and the invoicing of goods. At July 31, 2002 and 2001,
accounts receivable included bill and hold receivables of approximately
$1,659,000 and $867,000, respectively.

LEASE OBLIGATIONS

Aggregate future minimum rental commitments at July 31, 2002 under operating
leases for property and equipment are as follows:

Rent expense aggregated $1,310,000, $502,000 and $429,000 for fiscal 2002, 2001
and 2000, respectively, which includes amounts previously allocated to the
discontinued operations.

12.  STOCKHOLDERS' EQUITY

An aggregate of 375,000 shares of Common Stock was reserved for issuance or
available for grant under the Company's 1991 Employee Stock Option Plan (the
"1991 Employee Plan"), which expired in fiscal 2001. All options outstanding at
July 31, 2001 under the 1991 Employee Plan have a term of five years and are
exercisable in full. At July 31, 2002, options to purchase 1,875 shares of
Common Stock were outstanding under the 1991 Employee Plan. No additional
options will be granted under the 1991 Employee Plan.

An aggregate of 1,500,000 shares of Common Stock is reserved for issuance or
available for grant under the Company's 1997 Employee Stock Option Plan, as
amended (the "1997 Employee Plan"), through October 15, 2007. Options under the
1997 Employee Plan are granted at no less than 100% of the market price at the
time of the grant, typically become exercisable in four equal annual
installments and expire up to a maximum of ten years from the date of the grant.
At July 31, 2002, options to purchase 918,492 shares of Common Stock were
outstanding under the 1997 Employee Plan and 381,075 shares were available for
grant.

An aggregate of 300,000 shares of Common Stock was reserved for issuance or
available for grant under the Company's 1991 Directors'

                                       25
<Page>

Stock Option Plan (the "1991 Directors' Plan"), which expired in fiscal 2001.
All options outstanding at July 31, 2001 under the 1991 Directors' Plan have a
term of ten years and are exercisable in full. At July 31, 2002, options to
purchase 121,500 shares of Common Stock were outstanding under the 1991
Directors' Plan. No additional options will be granted under the 1991 Directors'
Plan.

An aggregate of 300,000 shares of Common Stock is reserved for issuance or
available for grant under the Company's 1998 Directors' Stock Option Plan (the
"1998 Directors' Plan"). Options under the 1998 Directors Plan are granted to
directors only at no less than 100% of the market price at the time of grant.
Under the plan, options to purchase 1,500 shares are granted annually on the
last business day of the Company's fiscal year to each member of the Company's
Board of Directors. The annual options are exercisable, as to 50% of the number
of shares, on the first anniversary of the grant of such options and are
exercisable for the balance of such shares on the second anniversary of the
grant of such options. On a quarterly basis, options to purchase 750 shares are
granted to each member of the Company's Board, except for employees of the
Company, in attendance at that quarter's Board of Directors meeting. The
quarterly options are exercisable immediately. Options granted prior to July 31,
2000 have a term of ten years and options granted on or after July 31, 2000 have
a term of five years. At July 31, 2002, options to purchase 91,500 shares of
Common Stock were outstanding under the 1998 Directors' Plan and 208,500 shares
were available for grant.

The Company also has outstanding 329,625 non-plan options at July 31, 2002 which
have been granted at the market price at the time of grant and expire up to a
maximum of ten years from the date of grant.

In accordance with the provisions of SFAS 123, the Company has elected to follow
APB Opinion 25 and related interpretations in accounting for its stock option
plans and, accordingly, does not recognize compensation expense. If the Company
had elected to recognize compensation expense based on the fair value of the
options granted at grant date as prescribed by SFAS 123, income and diluted
earnings per share from continuing operations would have been $5,937,000 and
$0.61, respectively, for fiscal 2002, $3,702,000 and $0.50, respectively, for
fiscal 2001 and $2,458,000 and $0.37, respectively, for fiscal 2000. The pro
forma effect on income from continuing operations for these years may not be
representative of the pro forma effect on income from continuing operations in
future years because it does not take into consideration pro forma compensation
expense related to grants made prior to fiscal 1996.

The fair value of each option grant is estimated on the date of

                                       26
<Page>

grant using the Black-Scholes option valuation model with the following
assumptions: expected dividend yield of 0%; expected stock price volatility
ranging from .31 to .69; risk-free interest rate at date of grant ranging from
3.59% to 6.10%; and expected weighted average option lives of 1-10 years.
Additionally, all options were considered to be non-deductible for tax purposes
in the valuation model. The weighted average fair value of options granted in
fiscal 2002, 2001 and 2000 was $5.62, $7.29 and $2.65 per share, respectively.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility and the
expected life. Because the Company's stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing model does not necessarily provide a reliable
single measure of the fair value of its employee stock options.

13.  EARNINGS PER COMMON SHARE

Basic earnings per common share are computed based upon the weighted average
number of common shares outstanding during the period.

Diluted earnings per common share are computed based upon the weighted average
number of common shares outstanding during the period plus the dilutive effect
of common stock equivalents using the treasury stock method and the average
market price for the period.

As described in note 1 to the Consolidated Financial Statements, the
calculations of weighted average common shares and earnings per share for all
periods presented reflect the May 2002 stock split.

(1)  The Company's acquisition of Minntech is reflected in the results of
     continuing operations for the portion of fiscal 2002 subsequent to its
     acquisition on September 7, 2001, and is not reflected in the results of
     continuing operations for fiscal 2001.

(2)  The summation of quarterly earnings per share does not equal fiscal 2002
     earnings per share due to rounding.

(3)  Earnings per share for the first and second quarters of fiscal 2002 and all
     four quarters of fiscal 2001 have been adjusted from amounts previously
     reported to reflect a three-for-two stock split effected in the form of a
     50% stock dividend paid in May 2002. Such adjustments are consistent with
     the presentation of the third and fourth quarters of fiscal 2002.
