Medical and Infection Control Products

    Medical and Infection Control Products are the Company's major source of 
revenue and profitability.  This segment is comprised of the medical and 
infection control equipment distributed by Carsen and infection control 
equipment manufactured and sold by MediVators through its worldwide 
distribution network.  

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

    An endoscope is a device comprised of an optical 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 of 
various disorders. Endoscopy enables physicians to study and photograph 
certain organs and body tissue and, if necessary, to perform a biopsy 
(removal of a small piece of tissue for microscopic analysis).  Many surgical 
procedures that formerly required a major operation are now performed much 
more simply by endoscopy, which can often be performed without general 
anesthesia.

                                        - 3 -

<PAGE>

    A flexible endoscope generally consists of fiberoptic image and light 
carrying bundles contained in a flexible tube, which can be inserted into 
irregularly shaped organs of a patient's body, such as the large intestine.  
The viewing end of a flexible fiberoptic endoscope contains an eyepiece and a 
steering mechanism and is connected to an external light source, which 
permits a surgeon to view inside a patient's body.  The tip of a flexible 
endoscope inserted into a patient's body contains a lens 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.  In an advanced version of the 
flexible    endoscope, known as a flexible video endoscope, the fiberoptic 
image and light carrying bundles have been replaced by a high resolution 
solid state image sensor that enables a picture to be transmitted 
electronically to a monitor, which picture can be viewed by a group of 
physicians and nurses as a medical procedure is being performed.  The 
flexible video endoscope comprises the majority of Carsen's flexible 
endoscopy sales.

    A rigid endoscope is a straight, narrow viewing 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.

    A technology known as minimally invasive surgery requires the use of a 
rigid endoscope.  With the addition of a tiny telescopic lens, a light source 
and a palm-size video camera, a rigid endoscope utilized for minimally 
invasive surgery can transmit images of the patient's organs, as well as the 
instrument being used by the surgeon, to a viewing monitor.  Minimally 
invasive surgery enables a surgeon using an endoscope to operate on a patient 
through small keyhole type incisions, avoiding, in many cases, the need for 
open surgery.  For example, one type of rigid endoscope known as a 
laparoscope, enables a surgeon to remove a gall bladder by making four or 
five small incisions in the abdomen, rather than one larger incision.  In 
this procedure, the surgeon inserts the laparoscope through one of the 
incisions to view the gall bladder while operating with surgical instruments 
inserted in other incisions.  This procedure can significantly reduce 
surgical trauma and post-operative pain, with reduced recovery time.  
Minimally invasive surgery has applications for a growing number of surgical 
procedures in addition to gall bladder removal, including hernia repair, 
small bowel resection, lung biopsy and advanced gynecological procedures.

    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 

                                        - 4 -

<PAGE>


commonly used for urology, gynecology, orthopedics, and general surgery, 
including minimally invasive surgery.

    Carsen also distributes various specialized medical instruments and 
accessories utilized in both rigid and flexible 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); 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), Argus Medical Company Inc. (surgical 
instruments), Sony of Canada Ltd. (video monitors, recorders and printers) 
and MediVators (endoscope disinfection equipment and medical sharps disposal 
systems).
    
    Infection Control Equipment.  MediVators' principal source of revenue is 
from the manufacturing and distribution of endoscope disinfection equipment 
and related accessories to hospitals through various distributors in the 
United States and internationally.

    MediVators' primary product is the DSD-91, which received FDA clearance 
of its 510(k) premarket notification in March 1994, and is a microprocessor 
controlled dual endoscope disinfection system.  The DSD-91 will disinfect two 
endoscopes at a time, can be used on a broad variety of endoscopes and is 
programmable by the user.  MediVators also manufactures a single scope 
disinfection unit, the SSD, which is based upon the same design as the DSD-91.

    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.  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 microbe contamination.  The chemical disinfectant to be 
used in the disinfecting process generally will be selected by hospital 
personnel based on the object to be disinfected, the hospital facilities and 
the disinfectants available.

                                        - 5 -

<PAGE>

    After manual cleaning, an endoscope is placed in the reservoir of the 
DSD-91 disinfector which then disinfects the endoscope by pumping 
disinfectant throughout the endoscope, including the endoscope's working 
channels.  The disinfector is a delivery system to ensure that the endoscope, 
including the working channels, will be exposed to the disinfectant for the 
recommended period of time.  The disinfector is operated by medical personnel 
such as gastrointestinal assistants.  Minimal training is required to operate 
the disinfector.  MediVators believes that the use of its endoscope 
disinfection equipment will result in more thorough disinfection.

    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 to the disinfectant.  This process can 
also inhibit the build up of residue in the working channels.  In addition, 
the entire disinfecting 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 risk of 
inconsistent manual disinfecting.

    MediVators also manufactures and distributes medical sharps disposal 
systems which provide for point-of-use destruction and decontamination of 
most types of disposable medical sharps waste, such as syringes, scalpels, 
razors and IV needles.  Sales of sharps disposal systems were not significant 
in fiscal 1997.

Scientific Products

    The Scientific Products segment is comprised of the precision instruments 
and the industrial technology equipment  distributed by Carsen and 
MediVators' MedFab custom plastics fabrication operation.

    Precision Instruments.  Carsen distributes Olympus microscopes and 
complementary scientific equipment and accessories.  Other precision 
instruments distributed by the Company include Narishige U.S.A., Inc. 
micromanipulators (which enable a viewer to manipulate objects being viewed 
under a microscope); Media Cybernetics, Inc. high resolution image analysis 
software and hardware; Tecan U.S. Inc. microplate readers, fluorometers and 
washers (photometric measurement systems); and Sheldon Manufacturing, Inc. 
incubators, warming ovens and water baths (temperature control instruments) 
and anaerobic chambers (controlled atmosphere for bacteriology applications), 
as well as optical accessories such as high contrast optics, objectives 
(magnifying lenses) and reticules and video calipers (both of which measure 
objects being viewed under a 

                                        - 6 -

<PAGE>

microscope).  The products are used in numerous disciplines for the 
microscopic study of objects and are sold directly to the end user.

    The precision instruments distributed by Carsen are sold to hospitals for 
cytology, pathology and histology purposes; government laboratories for 
research and forensics; universities and other educational institutions for 
research and teaching purposes; and private and industrial laboratories for 
bio-technology, geology, pharmacology, metallography, quality control and 
manufacturing applications.

    Industrial Technology Equipment.  Carsen distributes three types of 
industrial technology equipment that are similar to endoscopes, but are 
designed for a market known as remote visual inspection ("RVI".)  RVI is the 
application of endoscopic technology for industrial uses.  These products 
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.

    Carsen also has a number of products under its own trademark, "Optiscan." 
These products have been sourced from outside suppliers or designed by 
Carsen. Most Optiscan products currently available complement or enhance the 
Olympus RVI business.  Optiscan products include IVS (integrated video 
systems) video documentation products which integrate video camera, monitor 
and VCR in one portable unit; ultra-thin quartz glass fiberscopes for 
specialized applications, particularly in the nuclear power industry; and IAS 
(Image Archiving System) which consists of specialized software enabling the 
user to capture and archive high-resolution digital images.  The IAS product 
has medical, precision and industrial applications.

    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 develops new applications for its products, which are 
then customized by Carsen for such applications, based upon the nature of a 
company's business.   

                                        - 7 -

Product Service 
    
    Carsen operates a service organization at its Markham, Ontario facility 
that provides warranty and out-of-warranty service and repairs for medical, 
infection control and scientific products distributed by Carsen.  These 
products bear a product warranty that entitles the purchaser to warranty 
repairs and service at a nominal or no charge during the warranty period.  
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 the 
out-of-warranty service of these products.  

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

Consumer Products

    Carsen distributes consumer products in Canada, comprised principally of 
photographic and optical equipment.  This equipment, most of which is 
manufactured by Olympus, includes 35 mm. lens shutter cameras (also known as 
"point and shoot" cameras), 35 mm. single lens reflex cameras, APS (advanced 
photo systems) cameras, digital cameras, binoculars, light meters, and other 
photographic products and accessories.  Carsen also distributes Olympus 
hand-held dictation equipment and accessories.

    Two new camera systems, APS and digital, were introduced in fiscal 1997. 
The APS camera models utilize an easier, drop-in cartridge system and offer a 
selection of print formats.  Digital cameras, unlike conventional 35 mm. 
cameras, digitize and store images on a removable memory card inserted into 
the camera.  These stored, digitized images can be downloaded to a computer, 
where images can then be enhanced, manipulated and printed.  
    
    Carsen distributes its consumer products primarily to independent 
retailers, cooperative buying groups, large retail store chains and major 
department stores. Carsen also distributes such products to government 
agencies, school boards, the military, promotional sales organizations and 
catalog houses and other end-users.

                                        - 8 -

<PAGE>


    Carsen operates a service organization at its Markham, Ontario facility, 
as well as contracts with independent service centers throughout Canada to 
provide warranty service for the consumer products distributed by Carsen.  
Pursuant to the Olympus Agreement, Carsen is required to provide warranty 
service for all Olympus cameras presented to Carsen for service, whether or 
not such cameras were sold by Carsen.  This obligation has not had a material 
adverse effect on Carsen.  Carsen generally provides a two year warranty for 
35 mm. and APS cameras and a one year warranty for digital cameras and other 
consumer products. Carsen also provides out-of-warranty service for its 
consumer products.

Distribution Agreements

    Olympus Agreement.  The majority of Carsen's sales of medical, scientific 
and consumer products have been made pursuant to the Olympus 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 agreement bear the "Olympus" trademark.  The Olympus Agreement expires on 
March 31, 2001.  Carsen, or its predecessor, has been distributing Olympus 
products in Canada since 1949.

    During the term of the Olympus Agreement, 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 Agreement.  

    The Olympus Agreement imposes minimum purchase obligations on Carsen with 
respect to each of medical equipment, precision instruments, industrial 
technology equipment and consumer products.  The aggregate annual minimum 
purchase obligations for all such products (excluding digital camera 
products) are approximately $13.9 million, $15.5 million, $17.3 million and 
$19.4 million during the contract years ending March 31, 1998, 1999, 2000 and 
2001, respectively.  

    Subject to an allowance of a 10% shortfall from the minimum purchase 
requirements in certain situations, Olympus has the right to terminate the 
Olympus Agreement with respect to each product group for which Carsen has 
failed to meet the minimum purchase requirements.  If Carsen fails to meet 
such requirements for both precision instruments and industrial technology 
equipment, or for medical equipment, then Olympus has the right to terminate 
the entire Olympus Agreement.  Olympus may also terminate the Olympus 
Agreement if Carsen breaches its other obligations under the Olympus 
Agreement.  

    MediVators Agreement.  MediVators has a three year agreement with Olympus 
which expires on April 30, 1999, under which Olympus was granted the 
exclusive right to distribute certain endoscope disinfection equipment and 
related accessories 

                                        - 9 -

<PAGE>

in the United States, Central and South America, the Caribbean, and the West 
Indies (excluding Bermuda).  All products sold by Olympus pursuant to this 
agreement bear both the "Olympus" and "MediVators" trademarks.

    This agreement imposes minimum purchase obligations on Olympus.  Failure 
to achieve the minimum purchase requirement in any contract year would give 
MediVators the right to terminate the agreement.

Marketing

    Carsen markets its products for each industry segment through separate, 
dedicated sales forces comprised primarily of its own employees who are 
compensated on a salary and commission basis.

    MediVators sells its endoscope disinfection equipment and related 
accessories, both in the United States and internationally, to distributors 
which generally operate under exclusive distribution agreements.  MediVators 
generally sells its medical sharps disposal systems, both in the United 
States and internationally, through either exclusive distribution agreements 
or sales representatives.  

Effect of Currency Fluctuations and Trade Barriers

    A substantial portion of the Company's products are imported from the Far 
East and Western Europe, and 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 and Canada.

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 distributed by the Company.  In some 
areas, 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

quality product service, particularly with respect to medical and infection 
control products, the numerous customer contacts developed during its lengthy 
service as a distributor of Olympus products and the distribution arrangement 
for certain MediVators infection control products with Olympus, give the 
Company a competitive advantage with respect to certain of its products.

Government Regulation
    
    MediVators' products are subject to regulation by the United States Food 
and Drug Administration ("FDA"), which regulates the testing, manufacturing, 
packaging, distribution and marketing of medical devices in the United 
States, including certain products manufactured by MediVators.  Delays in FDA 
review of proposed new products can significantly delay new product 
introduction and may result in a product becoming "dated" or losing its 
market opportunity before it can be introduced.  Certain of 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 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 Medical Device Amendments of 1976 to the Food, Drug and Cosmetic Act, 
amended in 1990 and 1997 (the "Act"), also requires 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 makes 
inspections of medical device manufacturers and may issue reports or 
citations where the manufacturer has failed to comply with appropriate 
regulations and procedures.  Compliance with the provisions of the Act and 
the FDA's regulations is time-consuming and expensive.  On March 18, 1996, 
the FDA conducted a routine General Manufacturing Practices inspection and 
MediVators was found to be in a general state of control and no FD-483 
complaint was issued.  Federal, state and foreign regulations regarding the 
manufacture and sale of MediVators' products are subject to change.  
MediVators cannot predict what impact, if any, such changes might have on its 
business.

License Agreement

    MediVators is a party to an exclusive worldwide license agreement with 
the Mayo Foundation for Medical Education and Research (the "Mayo 
Foundation") which grants MediVators a license 

                                        - 11 -

<PAGE>

to manufacture and sell certain related patented equipment known as the OTT 
Disinfector for flexible endoscopes ("OTT Disinfector") and to use certain 
related proprietary know-how of the Mayo Foundation (the "License 
Agreement"). The License Agreement expires on December 31, 2005.  Under the 
License Agreement, MediVators must pay a royalty equal to five percent (5%) 
of the net revenues received by MediVators from sales of the OTT Disinfector 
and enhancements or improvements to the OTT Disinfector.  Although MediVators 
no longer sells the OTT Disinfector, it pays the Mayo Foundation a royalty on 
revenues from sales of a successor line of disinfector product developed by 
MediVators known as the DSD-91.  This product does not utilize the patented 
technology of the OTT Disinfector but did evolve from certain licensed 
know-how related thereto.  

Patents and Proprietary Rights

    MediVators holds patents on certain of its medical sharps disposal 
systems which it believes are of material importance to MediVators.  However, 
MediVators does not currently hold any patents with respect to its endoscope 
disinfection equipment.  Its current disinfector product, the DSD-91, 
utilizes certain know-how developed by the Mayo Foundation pursuant to the 
License Agreement, but has no patent protection.

Backlog

    On October 8, 1997, the Company's consolidated backlog was approximately 
$1,870,000, compared with approximately $860,000 on October 4, 1996.

Employees

    As of October 8, 1997, the Company employed 150 persons.  Of the 
Company's employees, 101 are located in Canada and 49 are located in the 
United States; 15 are executives and/or managers, 40 are engaged in sales, 8 
are engaged in customer service, 26 are engaged in product service, 31 are 
engaged in manufacturing, shipping and warehouse functions, 23 perform 
various administrative functions and 7 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.

Item 2.  PROPERTIES.

    Carsen leases a building, containing approximately 41,000 square feet, 
located in Markham, Ontario.  This facility is used for warehouse, service

five years.  The lease provides for monthly base rent of approximately 
$10,000 for the remainder of the lease term.

    MediVators leases approximately 27,500 square feet of commercial space, 
located in Eagan, Minnesota.  This facility is used for manufacturing,

30, 2001, subject to the Company's option to renew for five years.  The lease 
provides for monthly base rent of approximately $13,000 for the next two 
years and approximately $14,000 for the last two years.

    The Company leases approximately 2,000 square feet of office space in 
Clifton, New Jersey, for its executive offices.  The lease, which expires in 
January 2000, provides for monthly base rent of approximately $3,500.

    The Company believes that its facilities are adequate for its current 
needs.

Item 3.  LEGAL PROCEEDINGS.

    In November 1995, the Company was one of over 100 named defendants in the 
lawsuit titled "Caldwell Trucking PRP Group v. ADT Automotive, Inc., 
including Cantel Industries, Inc." (Civ. No. 95-1690  (WGB) brought by nine 
companies which settled a Comprehensive Environmental Response Compensation 
and Liability Act claim by the United States Government and the State of New 
Jersey for contribution to the remediation costs of an alleged hazardous 
waste site in New Jersey.  This lawsuit is currently pending in the United 
States District Court for the District of New Jersey.  The complaint, which 
relates to alleged septic and/or industrial waste disposed of prior to 1984, 
seeks total past and future remediation costs from the named defendants and 
prior settling companies estimated at approximately $20 million, but does not 
allege any specific offense against the Company at this time.  Management of 
the Company believes that Cantel was not engaged in the production, 
transportation or dumping of industrial waste at any time.  Currently, the 
Company is participating in an alternative dispute resolution ("ADR") 
process.  The ADR process is expected to conclude during calendar 1998, with 
proposed allocations to each ADR participant.  Although the Company can make 
no estimate of what its share, if any, of this total potential exposure could 
be, based on its current knowledge and available information, management 
believes that the claim will not have a material adverse effect on the 
Company.  Furthermore, notwithstanding the ADR process, the Company believes 
that it has defenses to the suit and that it may have insurance covering such 
claims in whole or in part.

    In February 1996, an arbitration proceeding was commenced against 
MediVators titled "Pioneer Medical, Inc. vs. MediVators, Inc."  The 
plaintiff, a former sales representative of MediVators, alleges an 
unspecified amount due for future sales of MediVators' products in the 
plaintiff's former sales territory, as well as other ancillary claims and 
punitive damages.  MediVators has asserted a counterclaim of approximately 
$25,000 for unpaid products sold to this former sales representative.  An 
arbitration hearing date is tentatively set for November 1997.  Recently, the 
plaintiff commenced a lawsuit against MediVators titled "Pioneer Medical, 
Inc. vs. MediVators, Inc." in Connecticut State Court alleging claims that 
appear to be identical to those in the arbitration matter. MediVators has not 
yet had an opportunity to formally respond to this lawsuit. Management 
believes that the claims alleged in both the arbitration matter and lawsuit 
are unmeritorious and intends to vigorously defend itself in these actions, 
and that the claims will not have a material adverse effect on the Company.

Item 4.  SUBMISSION OF MATTERS TO A 
         VOTE OF SECURITY HOLDERS.

    No matters were submitted to a vote of security holders during the fourth 
quarter of fiscal 1997.

Item 6.  SELECTED CONSOLIDATED FINANCIAL DATA.

    The financial data in the following table is qualified in its entirety 
by, and should be read in conjunction with, the financial statements and 
notes thereto and other information incorporated by reference in this Form 
10-K.  The Merger of Cantel and MediVators on March 15, 1996 has been

MediVators have been consolidated at their historical amounts for all periods 
presented and the Company's previously issued financial statements are 
restated as though MediVators had always been consolidated as a wholly-owned 
subsidiary.  For fiscal 1997, 1996, 1995 and 1994, the data below has been 
extracted from the audited consolidated financial statements of the Company 
as of and for each of the years ended July 31.  For fiscal 1993, the data

1993, except for the weighted average number of common and common equivalent 
shares and the common shares outstanding which are combined as of July 31 of

         CONDITION AND RESULTS OF OPERATIONS. 

Results of Operations

     The results of operations described hereafter reflect primarily the 
results of Carsen and MediVators.  There was no significant impact upon the 
Company's results of operations for fiscal 1997 compared with fiscal 1996, or 
fiscal 1996 compared with fiscal 1995, as a result of translating Canadian 
dollars into United States dollars.

       Fiscal 1997 compared with Fiscal 1996

       Net sales increased by $5,195,000, or 17.4%, to $34,987,000 in fiscal 
1997, from $29,792,000 in fiscal 1996.  This increase was principally 
attributable to the increased sales of Medical and Infection Control Products 
and Consumer Products.  The increased sales of Medical and Infection Control 
Products was primarily attributable to an increase in demand for both medical 
products and infection control products.  This increase includes the full 
year impact of the strategic alliance with Olympus America Inc. ("Olympus") 
for the sale of MediVators' endoscope disinfection equipment, as described in 
Note 7 to the Consolidated Financial Statements; expansion and improvement of 
the international distribution of MediVators' infection control products; and 
the improvement in economic conditions in Canada, where sales of medical 
products during fiscal 1996 were adversely impacted by certain cost control 
measures implemented by various provincial governments which decreased or 
delayed funding to 

                                       - 20 -

hospitals, thereby reducing hospital spending for capital equipment.  

       Net sales of Consumer Products in fiscal 1997 increased by
approximately 31% over fiscal 1996 and represented approximately 16% of the
Company's net sales during fiscal 1997, compared with 14% during fiscal 1996. 
The increased sales of Consumer Products for fiscal 1997 were due primarily
to stronger demand from national accounts for certain 35 mm. camera models,
where price reductions received from Olympus on such models were partially
passed along to customers, as well as the demand for digital cameras, which
were introduced during fiscal 1997.  As a result, there was a significant
reduction in the operating loss generated by Consumer Products during fiscal
1997.                   

       Gross profit increased by $1,299,000, or 12.5%, to $11,658,000 in
fiscal 1997, from $10,359,000 in fiscal 1996.  The gross profit margin as a
percentage of sales decreased to 33.3% in fiscal 1997, from 34.8% in fiscal
1996.  The lower gross profit margin for fiscal 1997 was primarily
attributable to more competitive sales of medical products and the increased
sales of consumer products, which generally have lower profit margins. 
Partially offsetting these decreases in margin were increased sales volume of
medical and infection control products, which generally have higher profit
margins, and a more efficient method of repairing endoscopes.

       Shipping and warehouse expenses decreased by $89,000 to $590,000 for
fiscal 1997, from $679,000 for fiscal 1996.  The decrease was attributable to
reductions in freight costs, rent and personnel costs.

       Selling expenses as a percentage of net sales were 12.6% for fiscal
1997, compared with 14.6% for fiscal 1996.  The decrease was attributable to
the impact of the increased sales against the fixed portion of these
expenses, as well as the elimination of certain variable selling expenses
previously associated with the domestic distribution of MediVators' endoscope
disinfection equipment.

       General and administrative expenses increased by $156,000 to
$3,407,000 for fiscal 1997, from $3,251,000 for fiscal 1996.  The increase
was primarily attributable to increased personnel costs, some of which
represent incentive compensation, professional fees and MediVators'
relocation expenses.

       Research and development expenses increased by $215,000 to $589,000
for fiscal 1997, from $374,000 for fiscal 1996.  This increase was
substantially due to planned new product development at MediVators.  


                                       - 21 -
<PAGE>


       Costs associated with the Merger of $486,000 in fiscal 1996
represented expenses incurred in connection with the MediVators acquisition,
which was accounted for as a pooling of interests.

       Interest expense decreased to $143,000 in fiscal 1997, from $258,000
in fiscal 1996.  This decrease was attributable to a decrease in average
borrowings and lower average interest rates under the Carsen revolving credit
facility, partially offset by increased borrowings under the MediVators
revolving credit facility during fiscal 1997.  Additionally, during fiscal
1996, there was a recovery of interest at Carsen of approximately $103,000
related to the tax reassessments described in Note 6 to the Consolidated
Financial Statements.

       Income from operations before income taxes increased by $1,570,000 to
$2,528,000 for fiscal 1997, from $958,000 for fiscal 1996.

       Income taxes consist primarily of foreign income taxes imposed on the
Company's Canadian operations and Canadian withholding taxes on dividends
remitted by Carsen to Cantel in the United States.  The effective tax rate on
Canadian operations was 44.9% and 44.6% for fiscal 1997 and 1996,
respectively.  However, the consolidated effective tax rate is higher due to
the fact that losses generated by the Company's combined U.S. operations
cannot be used to offset income generated by the Canadian operations.  In
addition, income taxes for fiscal 1996 are net of a recovery of $182,000 of
taxes related to the tax reassessment described in Note 6 to the Consolidated
Financial Statements.

       No tax benefits have been recognized on the Company's United States
operations as a result of the losses generated in fiscal 1997 and prior
years.

       Fiscal 1996 compared with Fiscal 1995

       Net sales decreased by $4,333,000, or 12.7%, to $29,792,000 in fiscal
1996, from $34,125,000 in fiscal 1995.  This decrease was principally
attributable to the decreased sales of Medical and Infection Control Products
and Consumer Products.   The decreased sales of Medical and Infection Control
Products in fiscal 1996 was primarily attributable to a decrease in demand
for medical products, offset in part by an increase in demand for infection
control products.  The sales of medical equipment have been adversely
impacted in Canada by certain cost control measures implemented by various
provincial governments which decreased or delayed funding to hospitals,
thereby reducing hospital spending for capital equipment.  The new
distribution agreement with Olympus America Inc. entered into by MediVators
on May 1, 1996, as described in Note 7 to the Consolidated Financial
Statements, had a limited effect on net sales of infection control products
during 


                                       - 22 -
<PAGE>

fiscal 1996.  The decreased sales of Consumer Products resulted from lower
demand for product, primarily attributable to the loss of national account
business.  

       Although net sales of Consumer Products represented approximately
14%, 18%, and 23% of the Company's net sales during fiscal 1996, 1995 and
1994, respectively, Consumer Products has incurred operating losses for each
of the past three fiscal years.  The lack of growth and profitability of
Consumer Products has resulted principally from lower demand for product. 
During fiscal 1996 and 1995, the reduced demand and increased operating
losses were primarily attributable to the loss of national account business,
either through the total loss of customers or the reduction of orders.  The
Company has undertaken steps to address the current market conditions by
restructuring the Consumer Products' sales functions and marketing
strategies.  Additionally, in fiscal 1997, Olympus extended price reductions
on certain camera models in order to make Olympus cameras more price
competitive in Canada, where all other significant manufacturers of cameras
distribute on a direct basis. 

       Gross profit decreased by $62,000, or 0.6%, to $10,359,000 in fiscal
1996, from $10,421,000 in fiscal 1995.  The gross profit margin as a
percentage of sales increased to 34.8% in fiscal 1996, from 30.5% in fiscal
1995.  The higher gross profit margin was principally attributable to a
provision for slow-moving infection control inventory recorded in fiscal
1995, the sales mix in all divisions, the decreased sales of Consumer
Products which generally have lower profit margins and a more efficient
method of repairing endoscopes.  These margin increases were partially offset
by price increases received from Olympus, a portion of which could not be
passed on through higher selling prices.

       Shipping and warehouse expenses decreased by $107,000 to $679,000 for
fiscal 1996, from $786,000 for fiscal 1995.  The decrease was attributable to
reductions in freight costs, rent and personnel costs.

       Selling expenses as a percentage of net sales were 14.6% for fiscal
1996, compared with 14.8% for fiscal 1995.  The impact of the reduced sales
against the fixed portion of these expenses was offset in part by a reduction
in fixed selling expenses.

       General and administrative expenses decreased by $269,000 to
$3,251,000 for fiscal 1996, from $3,520,000 for fiscal 1995.  The decrease
was primarily attributable to a cost reduction program implemented at Carsen,
as well the write-down of certain MediVators' assets to their estimated net
realizable value in fiscal 1995.

       Costs associated with the Merger of $486,000 in fiscal 1996
represented expenses incurred in connection with the MediVators acquisition,
which was accounted for as a pooling of interests.

       Interest expense decreased to $258,000 in fiscal 1996, from $492,000
in fiscal 1995.  This decrease is due to a recovery of interest of
approximately $103,000 related to the tax reassessments described in Note 6
to the Consolidated Financial Statements and a decrease in average borrowings
and lower average interest rates under the Canadian revolver.

       Income from operations before income taxes increased by $750,000 to
$958,000 for fiscal 1996 from $208,000 for fiscal 1995.

       Income taxes represent taxes imposed on the Company's Canadian
operations and Canadian withholding taxes on dividends remitted by Carsen to
Cantel in the United States.  In addition, income taxes for fiscal 1996 are
net of a recovery of $182,000 of taxes related to the tax reassessment
described in Note 6 to the Consolidated Financial Statements.

       No tax benefits have been recognized on the Company's United States
operations as a result of the losses generated in fiscal 1996 and prior
years.

Liquidity and Capital Resources

    At July 31, 1997, the Company's working capital was $11,106,000,
compared with $11,373,000 at July 31, 1996.  This decrease primarily reflects
increases in accounts payable and income taxes payable, partially offset by
increases in accounts receivable and inventories.  Accounts receivable and
accounts payable at July 31, 1997 reflect increased sales and related product
purchases during the month of July 1997.

    Net cash provided by operating activities was $1,623,000 for fiscal 1997
and $2,133,000 for fiscal 1996, compared with net cash used in operating
activities of $2,059,000 for fiscal 1995.    In fiscal 1997, the net cash
provided by operating activities was primarily due to net income after
adjusting for depreciation and increases in accounts payable and accrued
expenses and income taxes payable, partially offset by increases in accounts
receivable and inventories.  In fiscal 1996, the net cash provided by
operating activities was primarily due to net income after adjusting for
depreciation and a decrease in accounts receivable, partially offset by a
decrease in accounts payable and accrued expenses.  The net cash used in
operating activities in fiscal 1995 was primarily due to a net loss after
adjusting for depreciation, an increase in accounts receivable and a decrease
in 


                                       - 24 -
<PAGE>

income taxes payable, partially offset by an increase in accounts payable and
accrued expenses.  

    Net cash used in investing activities was $373,000, $142,000 and
$134,000 in fiscal 1997, 1996 and 1995, respectively.

    Net cash used in financing activities was $1,276,000 in fiscal 1997 and
$2,108,000 in fiscal 1996, compared with net cash provided by financing
activities of $1,495,000 in fiscal 1995.  These changes were principally due
in fiscal 1997 and 1996 to the reduction of long-term debt, partially offset
by proceeds from the exercise of stock options and warrants, and in fiscal
1995 due to an increase in outstanding borrowings under the Canadian
revolving credit facility.

    The Company has two credit facilities, a $5,000,000 revolving credit
facility for Carsen, and a $2,000,000 revolving credit facility for
MediVators.                                         

    Pursuant to the terms of the Carsen revolving credit facility,
borrowings under such facility must be paid in full no later than December
31, 1999.  Borrowings outstanding at July 31, 1997 and 1996 are in Canadian
dollars and bear interest at rates ranging from lender's Canadian prime rate
to .75% above the prime rate, depending upon Carsen's debt to equity ratio. 
At July 31, 1997, the lender's Canadian prime rate was 4.75% and Carsen's
outstanding borrowings bear interest at such prime rate. Subsequent to July
31, 1997, the lender's prime rate increased to 5.25% and Carsen's outstanding
borrowings will bear interest at a rate of .25% above such prime rate.  A
commitment fee on the unused portion of this facility is payable in arrears
at a rate of .25% per annum, with interest on borrowings payable monthly. 
There were $798,000 of borrowings outstanding under this facility at July 31,
1997.

    Pursuant to the terms of the MediVators' revolving credit facility,
borrowings under such facility must be paid in full no later than December 3,
1998.  Borrowings bear interest at 1.5% above the lender's United States
prime rate.  The lender's prime rate was 8.5% at July 31, 1997.  A commitment
fee on the unused portion of this facility is payable in arrears at a rate of
 .5% per annum, with interest on borrowings payable monthly.  There were
$755,000 of borrowings outstanding under this facility at July 31, 1997.  

    Each of the credit facilities provide for restrictions on available
borrowings based primarily upon percentages of eligible accounts receivable
and inventories; require the subsidiary to meet certain financial covenants;
are secured by substantially all assets of the subsidiary; and are guaranteed
by Cantel.


                                       - 25 -

    A decrease in the value of the Canadian dollar against the United States
dollar could adversely affect the Company because the Company's Canadian
subsidiary purchases substantially all of its products in United States
dollars and sells its products in Canadian dollars.  Such adverse currency
fluctuations could also result in a corresponding adverse change in the
United States dollar value of the Company's assets that are denominated in
Canadian dollars. Under the Carsen credit facility the Company's Canadian
subsidiary has a $15,000,000 (U.S. dollars) foreign exchange hedging facility
which is available to be used to minimize future adverse currency
fluctuations as they relate to purchases of inventories. 

    The Company's Canadian subsidiary had foreign exchange forward contracts
at October 8, 1997 aggregating $9,000,000 (U.S. dollars) to hedge against
possible declines in the value of the Canadian dollar which would otherwise
result in higher inventory costs.  Such contracts represent the Canadian
subsidiary's projected purchases of inventories for the months of February
1998 through July 1998.

    The average exchange rate of the contracts open at October 8, 1997 was
$1.3574 Canadian dollar per United States dollar, or $.7367 United States
dollar per Canadian dollar.  The exchange rate published by the Wall Street
Journal on October 8, 1997 was $1.3723 Canadian dollar per United States
dollar, or $.7287 United States dollar per Canadian dollar.

    The Company believes that its anticipated cash flow from operations and
the funds available under the revolving credit facilities will be sufficient
to satisfy the Company's cash operating requirements for the foreseeable
future based upon the current level of operations.  At October 8, 1997,
approximately $5,500,000 was available under the credit facilities.

    As of July 31, 1997, the Company had net operating loss carryforwards
for United States income tax purposes ("NOLs") of approximately $16,350,000
which will expire through July 31, 2012.  Of this amount, approximately
$4,350,000 represents NOLs accumulated by MediVators prior to the Merger,
which may only be used against the future earnings of MediVators and are
subject to annual limitations due to the ownership change.

    In addition, the Company and its Canadian subsidiary cannot file
consolidated tax returns, for Canadian or United States income tax purposes. 
Therefore, neither net losses sustained by the Company in the United States
nor the NOLs can be utilized to reduce Canadian federal or provincial income
taxes payable by the Canadian subsidiary on its taxable income nor can losses
sustained by the Canadian subsidiary, if any, be used to offset taxable
income earned by the Company in the United States.  This has resulted in the
payment of income taxes by the Company in 


                                       - 26 -

Canada, notwithstanding net losses sustained by the Company in the United
States.

    Inflation has not significantly impacted the Company's operations.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders Cantel Industries, Inc.
 
We have audited the accompanying consolidated balance sheets of Cantel
Industries, Inc. as of July 31, 1997 and 1996 and the related consolidated
statements of operations, changes in stockholders' equity and cash flows for the
years then ended. 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 generally accepted auditing
standards. 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 Industries, Inc. at July 31, 1997 and 1996 and the consolidated results
of its operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles. 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.
 
We previously audited and reported on the consolidated statements of 
operations, changes in stockholders' equity and cash flows of Cantel 
Industries, Inc. for the year ended July 31, 1995, as well as the financial 
statement schedule listed in the Index at Item 14(a), prior to their 
restatement for the 


<PAGE>

1996 pooling of interests as described in Note 3. The contribution of Cantel 
Industries, Inc. to net sales and net income represented $31,079,000 and 
$1,001,000 of the respective restated 1995 totals. Financial statements of 
MediVators, Inc. included in the 1995 restated consolidated statements were 
audited and reported on separately by other auditors. The report of the other 
auditors who audited these statements appears elsewhere herein. We also have 
audited, as to combination only, the accompanying consolidated statements of 
operations, changes in stockholders' equity, and cash flows of Cantel 
Industries, Inc. for the year ended July 31, 1995, after restatement for the 
1996 pooling of interests; in our opinion, such consolidated financial 
statements have been properly combined on the basis described in Note 3 to 
the consolidated financial statements.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors 
 and Stockholders of 
 MediVators, Inc.
 
In our opinion, the consolidated statements of operations, of stockholders' 
equity and of cash flows for the year ended July 31, 1995 (not presented 
separately herein) present fairly, in all material respects, the results of 
operations and cash flows of MediVators, Inc. and its subsidiary for the year 
ended July 31, 1995, in conformity with generally accepted accounting 
principles. These financial statements are the responsibility of the 
Company's management; our responsibility is to express an opinion on these 
financial statements based on our audit. We conducted our audit of these 
statements in accordance with generally accepted auditing standards which 
require that we plan and perform the audit to obtain reasonable assurance 
about whether the financial statements are free of material misstatement. An 
audit includes examining, on a test basis, evidence supporting the amounts 
and disclosures in the financial statements, assessing the accounting 
principles used and significant estimates made by management, and evaluating 
the overall financial statement presentation. We believe that our audit 
provides a reasonable basis for the opinion expressed above. We have not 
audited the consolidated financial statements of MediVators, Inc. for any 
period subsequent to July 31, 1995.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                   Years Ended July 31, 1997, 1996 and 1995
 
1. BUSINESS DESCRIPTION
 
Cantel Industries, Inc. ("Cantel") has two wholly-owned subsidiaries 
(collectively known as the "Company"). Its Canadian subsidiary, Carsen Group 
Inc. ("Carsen" or "Canadian subsidiary") is engaged in the marketing, 
distribution and service of medical and infection control, scientific and 
consumer products in Canada. Its United States subsidiary, MediVators, Inc. 
("MediVators" or "United States subsidiary") was acquired in March 1996 and 
is engaged in the manufacturing, marketing, distribution and service of 
infection control products.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
The consolidated financial statements include the accounts of Cantel 
Industries, Inc. and its wholly-owned subsidiaries. All significant 
intercompany transactions and balances have been eliminated in consolidation.
 
REVENUE RECOGNITION
 
Revenue is generally recognized as products are shipped to customers, net of
provisions for sales allowances, warranties and similar items.
 
TRANSLATION OF FOREIGN CURRENCY FINANCIAL STATEMENTS
 
Assets and liabilities of Carsen are translated into United States dollars
at year-end exchange rates; income and expenses are translated using average
exchange rates during the year. The cumulative effect of the translation of
Carsen's financial statements is presented as a separate component of
stockholders' equity. Foreign exchange gains and losses related to the purchase
of inventories are included in cost of sales.

                                     8

<PAGE>
 
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
are removed from the respective accounts and any resulting gain or loss is
included in income. Depreciation and amortization are provided on either the
straight-line method or, for certain furniture and equipment at Carsen, the
declining balance method, over the estimated useful lives of the assets which
generally range from 3-7 years for furniture and equipment and the life of the
lease for leasehold improvements.
 
OTHER ASSETS
 
Inventories of sales samples which have not turned over within one year and 
medical loaners available for customers are included in other assets and are 
carried at the lower of cost or net realizable value.
 
STOCK BASED COMPENSATION
 
As permitted by FASB Statement 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 equals the fair market
value of the underlying common stock on the date of grant.
 
INCOME TAXES
 
The Company accounts for income taxes by the liability method in accordance
with Statement of Financial Accounting Standards No. 109 (SFAS No. 109)
"Accounting for Income Taxes".
 
No income taxes have been provided on the undistributed earnings ($10,740,000 
at July 31, 1997) of Carsen since the Company does not intend to repatriate 
such earnings unless no additional United States taxes would result upon such 
repatriation.

                                  9

<PAGE>
 
GOODWILL
 
Goodwill with respect to Carsen is not being amortized since, in the opinion
of management, there has been no diminution of value since acquisition prior to
1970. The carrying value of the goodwill is reviewed if the facts and
circumstances suggest that it may be permanently impaired. Such review is based
upon the undiscounted expected future operating profit derived from such
business. In the event such result is less than the carrying value of the
goodwill, the carrying value of the goodwill is reduced to an amount that
reflects the expected future benefit.
 
EARNINGS PER COMMON SHARE
 
Primary 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 and warrants using the treasury stock method and the average
market price for the period.
 
Fully 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 and warrants using the treasury stock method and the higher of
the period-end or average market price for the period.
 
The following average shares were used for the computation of primary and
fully diluted earnings per share:

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

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

3. ACQUISITION OF MEDIVATORS
 
On March 15, 1996, the Company consummated a merger transaction with 
MediVators, a Minnesota corporation, pursuant to an Agreement and Plan of 
Merger under which MediVators became a wholly-owned subsidiary of the 
Company, and the stockholders of MediVators received an equity interest of 
approximately 26.5% in Cantel (without giving effect to outstanding options 
and warrants to acquire stock of Cantel or MediVators) (the "Merger").
 
The Merger has been accounted for as a pooling of interests for accounting 
purposes in accordance with generally accepted accounting principles. Under 
this accounting treatment, the assets, liabilities, stockholders' equity, 
results of operations and cash flows of MediVators have been consolidated at 
their historical amounts for all periods presented and previously issued 
financial statements of the Company are restated as though MediVators had 
always been consolidated as a wholly-owned subsidiary.
 
A reconciliation of consolidated net sales and income (loss) from operations
to the respective amounts of each of Cantel and MediVators prior to the Merger
is as follows:

5. FINANCING ARRANGEMENTS
 
The Company has two credit facilities, a $5,000,000 revolving credit
facility for Carsen, and a $2,000,000 revolving credit facility for MediVators.
 
Pursuant to the terms of the Carsen revolving credit facility, borrowings
under such facility must be paid in full no later than December 31, 1999.
Borrowings outstanding at July 31, 1997 and 1996 are in Canadian dollars and
bear interest at rates ranging from lender's Canadian prime rate to .75% above
the prime rate, depending upon Carsen's debt to equity ratio. At July 31, 1997,
the lender's Canadian prime rate was 4.75% and Carsen's outstanding borrowings
bear interest at such prime rate. Subsequent to July 31, 1997, the lender's
prime rate increased to 5.25% and Carsen's outstanding borrowings will bear
interest at a rate of .25% above lender's prime rate. A commitment fee on the
unused portion of this facility is payable in arrears at a rate of .25% per
annum, with interest on borrowings payable monthly. There were $798,000 and
$3,419,000 of borrowings outstanding under this facility at July 31, 1997 and
1996, respectively.
 
Pursuant to the terms of the MediVators' revolving credit facility, 
borrowings under such facility must be paid in full no later than December 3, 
1998. Borrowings bear interest at 1.5% above the lender's United States prime 
rate. The lender's prime rate was 8.5% at July 31, 1997. A commitment fee on 
the unused portion of this facility is payable in arrears at a rate of .5% 
per annum, with interest on borrowings payable monthly. There were $755,000 
of borrowings outstanding under this facility at July 31, 1997 and no 
borrowings outstanding at July 31, 1996.
 
Each of the credit facilities provide for restrictions on available 
borrowings based primarily upon percentages of eligible accounts receivable 
and inventories; require the subsidiary to meet certain financial covenants; 
are secured by substantially all assets of the subsidiary; and are guaranteed 
by Cantel.

6. INCOME TAXES
 
During fiscal 1996, the Company negotiated a settlement with Revenue Canada
which related to a reassessment of federal and provincial income and withholding
taxes for the years 1990-1992 which had been paid by the Company under protest.
The settlement resulted in the recovery of federal and provincial income and
withholding taxes of approximately $182,000 and interest of approximately
$103,000.
 
Deferred income taxes recorded in the consolidated balance sheets at July
31, 1997 and 1996 include deferred tax assets related to net operating loss
carryforwards ("NOLs") of $5,559,000 and $5,232,000, respectively, which have
been fully offset by valuation allowances, and deferred tax liabilities related
to the use of accelerated methods of depreciation for income tax purposes of
$88,000 and $97,000, respectively. The valuation allowances have been
established equal to the full amount of the deferred tax assets, as the Company
was not assured at July 31, 1997 and 1996 that it was more likely than not that
a benefit will be realized.
 
For financial statement and domestic tax reporting purposes, the Company has
NOLs of approximately $16,350,000 at July 31, 1997, which expire through July
31, 2012. Of this amount, approximately $4,350,000 represents NOLs accumulated
by MediVators prior to the Merger, which may only be used against the future
earnings of MediVators and are subject to annual limitations due to the
ownership change. The NOLs presented are based upon the tax returns as filed and
are subject to examination by the Internal Revenue Service.
 
The provision (benefit) for income taxes consists of the following:

7. COMMITMENTS AND CONTINGENCIES
  DISTRIBUTION AGREEMENTS
    OLYMPUS AGREEMENT
 
The majority of Carsen's sales of medical, scientific and consumer products have
been made pursuant to an agreement with Olympus America, Inc. ("Olympus") 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
agreement bear the "Olympus" trademark. The Olympus Agreement expires on March
31, 2001.
 
During the term of the Olympus Agreement, 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 Agreement.
 
The Olympus Agreement imposes minimum purchase obligations on Carsen with
respect to each of medical equipment, precision instruments, industrial
technology equipment and consumer products. The aggregate annual minimum
purchase obligations for all such products (excluding digital camera products)
are approximately $13.9 million, $15.5 million, $17.3 million and $19.4 million
during the contract years ending March 31, 1998, 1999, 2000 and 2001,
respectively.
 
Subject to an allowance of a 10% shortfall from the minimum purchase
requirements in certain situations, Olympus has the 

                                     14

<PAGE>

right to terminate the Olympus Agreement with respect to each product group 
for which Carsen has failed to meet the minimum purchase requirements. If 
Carsen fails to meet such requirements for both precision instruments and 
industrial technology equipment, or for medical equipment, then Olympus has 
the right to terminate the entire Olympus Agreement. Olympus may also 
terminate the Olympus Agreement if Carsen breaches its other obligations 
under the Olympus Agreement.
 
MEDIVATORS AGREEMENT
 
MediVators has a three year agreement with Olympus which expires on April 30,
1999, under which Olympus was granted the exclusive right to distribute certain
endoscope disinfection equipment and related accessories in the United States,
Central and South America, The Caribbean, and the West Indies (excluding
Bermuda). All products sold by Olympus pursuant to this agreement bear both the
"Olympus" and "MediVators" trademarks.
 
This agreement imposes minimum purchase obligations on Olympus. Failure to
achieve the minimum purchase requirement in any contract year would give
MediVators the right to terminate the agreement.
 
Sales to Olympus 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, 1997 and 1996, accounts receivable included bill and hold
receivables of approximately $401,000 and $566,000, respectively.

LICENSE AGREEMENT
 
MediVators is a party to an exclusive worldwide license agreement with the Mayo
Foundation for Medical Education and Research (the "Mayo Foundation") which
grants MediVators a license to manufacture and sell certain related patented
equipment known as the OTT Disinfector for flexible endoscopes ("OTT
Disinfector") and to use certain related proprietary know-how of the Mayo
Foundation (the "License Agreement"). The License Agreement expires December 31,
2005. Under the License Agreement, MediVators must pay a royalty equal to five
percent (5%) of the net revenues received by MediVators from sales of the OTT
Disinfector and enhancements or improvements to the OTT Disinfector. Although
MediVators no longer sells the OTT Disinfector, it pays the Mayo Foundation a
royalty on revenue from sales of a successor line of disinfector product
developed by MediVators known as the DSD-91. This product does not utilize the
patented technology of the OTT Disinfector but did evolve from certain licensed
know-how related thereto.

FOREIGN EXCHANGE CONTRACTS
 
    The Company's Canadian subsidiary enters into foreign exchange forward
contracts to purchase United States dollars to hedge against currency
fluctuations affecting purchases of inventory. Total commitments for such
forward contracts amounted to approximately $5,459,000 at July 31, 1997, and
cover projected purchases of inventory for the months of July 1997 and May 1998
through July 1998. The fair value of such contracts at July 31, 1997, based upon
current market quotes for contracts with similar terms, approximated the
carrying value of such contracts.
 
LEASE OBLIGATIONS
 
    Aggregate future minimum rental commitments at July 31, l997 under operating
leases for warehouse and office space are as follows:

Rent expense aggregated $324,000, $283,000 and $316,000 for fiscal 1997, 1996 
and 1995, respectively. Of these amounts, approximately $17,000, $106,000 and 
$106,000 in fiscal 1997, 1996 and 1995, respectively, was paid to a director 
and former officer of MediVators who was the landlord of MediVators' former 
manufacturing, warehouse and office facility.


LITIGATION
 
    In November 1995, the Company was one of over 100 named defendants in the
lawsuit titled "Caldwell Trucking PRP Group v. ADT Automotive, Inc., including
Cantel Industries, Inc." (Civ. No. 95-1690 (WGB) brought by nine companies which
settled a Comprehensive Environmental Response Compensation and Liability Act
claim by the United States Government and the State of New Jersey for
contribution to the remediation costs of an alleged hazardous waste site in New
Jersey. This lawsuit is currently pending in the United States District Court
for the District of New Jersey. The complaint, which relates to alleged septic
and/or industrial waste disposed of prior to 1984, seeks total past and future
remediation costs from the named defendants and prior settling companies
estimated at approximately $20 million, but does not allege any specific offense
against the Company at this time. Management of the Company believes that Cantel
was not engaged in the production, transportation or dumping of industrial 

                                       16

<PAGE>

waste at any time. Currently, the Company is participating in an alternative 
dispute resolution ("ADR") process. The ADR process is expected to conclude 
during calendar 1998, with proposed allocations to each ADR participant. 
Although the Company can make no estimate of what its share, if any, of this 
total potential exposure could be, based on its current knowledge and 
available information, management believes that the claim will not have a 
material adverse effect on the Company. Furthermore, notwithstanding the ADR 
process, the Company believes that it has defenses to the suit and that it 
may have insurance covering such claims in whole or in part.

    In February 1996, an arbitration proceeding was commenced against MediVators
titled "Pioneer Medical, Inc. vs. MediVators, Inc." The plaintiff, a former
sales representative of MediVators, alleges an unspecified amount due for future
sales of MediVators' products in the plaintiff's former sales territory, as well
as other ancillary claims and punitive damages. MediVators has asserted a
counterclaim of approximately $25,000 for unpaid products sold to this former
sales representative. An arbitration hearing date is tentatively set for
November 1997. Recently, the plaintiff commenced a lawsuit against MediVators
titled "Pioneer Medical, Inc. vs. MediVators, Inc." in Connecticut State Court
alleging claims that appear to be identical to those in the arbitration matter.
MediVators has not yet had an opportunity to formally respond to this lawsuit.
Management believes that the claims alleged in both the arbitration matter and
lawsuit are unmeritorious and intends to vigorously defend itself in these
actions, and that the claims will not have a material adverse effect on the
Company.
 
8. STOCKHOLDERS' EQUITY
 
    The Company's 1991 Employee Stock Option Plan provides for the granting of
options to employees to purchase up to 250,000 shares of the Company's Common
Stock through January 2, 2001. Options under this 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, 1997, 70,625 shares were available
for grant under this plan.
 
    The Company's 1991 Directors' Stock Option Plan provides for the granting of
options to directors to purchase up to 200,000 shares of its Common Stock.
Options under this plan may be granted to directors only. Under the plan,
options to purchase 1,000 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 

                                       17

<PAGE>

for the balance of such shares on the second anniversary of the grant of such 
options. On a quarterly basis, options to purchase 500 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. The exercise price of each option is the 
fair market value on the date the option is granted, and the options expire 
ten years from the date of the grant. At July 31, 1997, 24,000 shares were 
available for grant under this plan.
 
    The Company also has outstanding non-plan options which have been granted at
the market price at the time of grant, are fully exercisable and expire up to a
maximum of ten years from the date of grant, and options granted by MediVators
prior to the Merger under the MediVators 1991 Stock Option Plan which became
fully exercisable as the result of the Merger. No future options will be granted
under the MediVators Stock Option Plan.
 
    The Company has adopted SFAS No. 123, "Accounting for Stock-Based
Compensation". In accordance with the provisions of SFAS No. 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 No.
123, net income and earnings per share would have been $847,000 and $0.19,
respectively, for fiscal 1997 and $316,000 and $0.07, respectively, for fiscal
1996. The pro forma effect on net income for 1997 and 1996 is not representative
of the pro forma effect on net income in future years because it does not take
into consideration pro forma compensation expense related to grants made prior
to 1996.
 
    The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option valuation model with the followings assumptions:
expected dividend yield of 0%; expected stock price volatility of .46; risk-free
interest rate at date of grant ranging from 5.18% to 6.59%; and expected
weighted average option lives of 4-10 years. The weighted average fair value of
options granted during 1997 was $3.90 per share.

    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.
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.
 
    There were an aggregate of 74,739 and 352,469 warrants outstanding to
purchase shares of Common Stock at July 31, 1997 and 1996, respectively, at

                           1997 EMPLOYEE STOCK OPTION PLAN
                                          OF
                               CANTEL INDUSTRIES, INC.

            (As adopted by the Board of Directors as of October 16, 1997)


         1.   The Plan.  This 1997 Employee Stock Option Plan (the "Plan") is
intended to encourage ownership of stock of Cantel Industries, Inc. (the
"Corporation") by specified employees of the Corporation and its subsidiaries
and to provide additional incentive for them to promote the success of the
business of the Corporation.

         2.   Stock Subject to the Plan.  Subject to the provisions of
Paragraph 14 hereof, the total number of shares of Common Stock, par value $.10
per share, of the Corporation (the "Stock") which may be issued pursuant to
Incentive Stock Options, as defined by Section 422 of the Internal Revenue Code
("ISOs"), under the Plan (the "Options") shall be 200,000.  Such shares of Stock
may be in whole or in part, either authorized and unissued shares or treasury
shares as the Board of Directors of the Corporation (the "Board") shall from
time to time determine.  If an Option shall expire or terminate for any reason
without having been exercised in full, the unpurchased shares covered thereby
shall (unless the Plan shall have been terminated) again be available for
Options under the Plan.

         3.   Administration of the Plan.   The Plan shall be administered by a
committee (the "Committee") composed of two or more non-employee members of the
Board which shall have plenary authority, in its discretion, to determine the
employees of the Corporation and its subsidiaries to whom Options shall be
granted ("Optionees"), the number of shares to be subject to each Option
(subject to the provisions of Paragraph 2), the option exercise price (the
"Exercise Price") (subject to the provisions of Paragraph 7), the vesting
schedule of each option and the other terms of each Option.  The Board shall
have plenary authority, subject to the express provisions of the Plan, to
interpret the Plan, to prescribe, amend and rescind any rules and regulations
relating to the Plan and to take such other action in connection with the Plan
as it deems necessary or advisable.  The interpretation and construction by the
Board of any provisions of the Plan or of any Option granted thereunder shall be
final and no member of the Board shall be liable for any action or determination
made in good faith with respect to the Plan or any Option granted thereunder by
the Committee.

                                           
<PAGE>

         4.   Employees Eligible for Options.    All employees of the
Corporation or its subsidiaries shall be eligible for Options.  In making the
determination as to employees to whom Options shall be granted and as to the
number of shares to be covered by such Options, the Committee shall take into
account the duties of the respective employees, their present and potential
contributions to the success of the Corporation and such other factors as it
shall deem relevant in connection with accomplishing the purpose of the Plan.

         5.   Term of Plan.  The Plan shall terminate on, and no Options shall
be granted after October 15, 2007 provided that the Committee may at any time
terminate the Plan prior thereto.

         6.   Maximum Option Grant.    With respect to an Option granted to an
individual that is intended to qualify as an ISO, the aggregate fair market
value (determined as of the time the Option is granted) of the Stock with
respect to which such Option and all other ISOs granted to the individual
(whether under this Plan or under any other stock option plan of the Corporation
or any of its subsidiaries) are exercisable for the first time during a calendar
year may not exceed $100,000.  

         7.   Exercise Price.     Each Option shall state the Exercise Price,
which shall be, in the case of ISOs, not less than 100% of the fair market value
of the Stock on the date of the granting of the Option, nor less than 110% in
the case of an ISO granted to an individual who, at the time the Option is
granted, is a 10% Holder (as hereinafter defined).  The fair market value of
shares of Stock shall be determined by the Board and shall be (i) the closing
price of the Stock on the date of the granting of the Option as reported by
NASDAQ or any quotation reporting organizations, or (ii) if the Stock did not
trade on such date, the mean between the high bid and low asked prices. 

         8.   Term of Options.    The term of each Option granted under this
Plan shall be for a maximum of ten years from the date of granting thereof, and
a maximum of five years in the case of an ISO granted to a 10% Holder, but may
be for a lesser period or be subject to earlier termination as hereinafter
provided.

         9.   Exercise of Options.     An Option may be exercised from time to
time as to any part or all of the Stock to which the Optionee shall then be
entitled, provided, however, that an Option may not be exercised (a) as to less
than 100 shares at any time (or for the remaining shares then purchasable under
the Option, if less than 100 shares), (b) prior to the expiration of at least
six months from the date of grant except in case of the death or 
disability of the Optionee and (c) unless the Optionee shall have 


                                       2
<PAGE>

been in the continuous employ of the Corporation or its subsidiaries from the
date of the granting of the Option to the date of its exercise, except as
provided in Paragraphs 12 and 13.  The Exercise Price shall be paid in full at
the time of the exercise of an Option (i) in cash or (ii) by the transfer to the
Corporation of shares of its Stock with a fair market value (as determined by
the Committee) equal to the purchase price of the Stock issuable upon exercise
of such Option.  The holder of an Option shall not have any rights as a
stockholder with respect to the Stock issuable upon exercise of an Option until
certificates for such Stock shall have been delivered to him after the exercise
of the Option.

         10.  Non-transferability of Options.    Except as provided in the
following sentence, an Option shall not be transferable otherwise than by will
or the laws of descent and distribution and is exercisable during the lifetime
of the employee only by him or his guardian or legal representative.  The
Committee shall have discretionary authority to grant Options which will be
transferable to members of an Optionee's immediate family, including trusts for
the benefit of such family members and partnerships in which such family members
are the only partners.  A transferred Option would be subject to all of the same
terms and conditions as if such Option had not been transferred.

         11.  Form of Option.     Each Option granted pursuant to the Plan
shall be evidenced by an agreement (the "Option Agreement") which shall clearly
identify the status of the Options granted thereunder (i.e., an ISO ) and which
shall be in such form as the Committee shall from time to time approve.  The
Option Agreement shall comply in all respects with the terms and conditions of
the Plan and may contain such additional provisions, including, without
limitation, restrictions upon the exercise of the Option, as the Committee shall
deem advisable.

         12.  Termination of Employment.    In the event that the employment of
an Optionee shall be terminated (otherwise by reason of death), such Option
shall be exercisable (to the extent that such Option was exercisable at the time
of termination of his employment) at any time prior to the expiration of a
period of time not exceeding three months after such termination, but not more
than ten years (five years in the case of an ISO granted to a 10% Holder) after
the date on which such Option shall have been granted.  Nothing in the Plan or
in the Option Agreement shall confer upon an Optionee any right to be continued
in the employee of the Corporation or its subsidiaries or interfere in any way
with the right of the Corporation or any subsidiary to terminate or otherwise
modify the terms of an Optionee's employment, provided, however, that a change
in an Optionee's duties or position shall not affect such Optionee's Option so
long as such Optionee is still an employee of the Corporation or one of its
subsidiaries. 

                                       3
<PAGE>

         13.  Death of Optionee.  In the event of the death of an Optionee, any
unexercised portion of such Optionee's Option shall be exercisable (to the
extent that such Option was exercisable at the time of his death) at any time
prior to the expiration of a period not exceeding three months after his death
but not more than ten years (five years in the case of an ISO granted to a 10%
Holder) after the date on which such Option shall have been granted and only by
such person or persons to whom such deceased Optionee's rights shall pass under
such Optionee's will or by the laws of descent and distribution.

         14.  Adjustments Upon Changes in Capitalization.  In the event of
changes in the outstanding Stock of the Corporation by reason of stock
dividends, splitups, recapitalizations, mergers, consolidations, combinations or
exchanges of shares, separations, reorganizations or liquidations, the number
and class of shares or the amount of cash or other assets or securities
available upon the exercise of any Option granted hereunder and the maximum
number of shares as to which Options may be granted to an employee shall be
correspondingly adjusted, to the end that the Optionee's proportionate interest
in the Corporation, any successor thereto or in the cash, assets or other
securities into which shares are converted or exchanged shall be maintained to
the same extent, as near as may be practicable, as immediately before the
occurrence of any such event.  All references in this Plan to "Stock" from and
after the occurrence of such event shall be deemed for all purposes of this Plan
to refer to such other class of shares or securities issuable upon the exercise
of Options granted pursuant hereto.

         15.  Shareholder and Stock Exchange Approval.     This Plan is subject
to and no Options shall be exercisable hereunder until after the approval by the
holders of a majority of the Stock of the Corporation voting at a duly held
meeting of the stockholders of the Corporation within twelve months after the
date of the adoption of the Plan by the Board.

         16.  Amendment of the Plan.   The Board shall have complete power and
authority to modify or amend the Plan (including the form of Option Agreement)
from time to time in such respects as it shall deem advisable; provided,
however, that the Board shall not, without the approval of the votes represented
by a majority of the outstanding Stock of the Corporation present or represented
at a meeting duly held in accordance with the applicable laws of the
Corporation's jurisdiction of incorporation and entitled to vote at a meeting of
stockholders or by the written consent of stockholders owning stock representing
a majority of the votes of the corporation's outstanding stock, (i) increase the
maximum number of shares which in the aggregate are subject to Options under the
Plan (except as provided by Paragraph 14), (ii) extend the term of the Plan or
the period during which Options may be granted or exercised, (iii) reduce the
Exercise Price, in the case of ISOs below 100% (110% in the case of an ISO
granted to a 10% Holder) of 

                                       4
<PAGE>

the fair market value of the Stock issuable upon exercise of Options at the time
of the granting thereof, other than to change the manner of determining the fair
market value thereof, (iv) increase the maximum number of shares of Stock for
which any employee may be granted Options under the Plan pursuant to Paragraph
6, (v) modify the requirements as to eligibility for participation in the Plan,
or (vi) amend the plan in any respect which would cause such options to no
longer qualify for ISO treatment pursuant to the Internal Revenue Code.  No
termination or amendment of the Plan shall, without the consent of the
individual Optionee, adversely affect the rights of such Optionee under an
Option theretofore granted to him or under such Optionee's Option Agreement.

         17.  Taxes.    The Corporation may make such provisions as it may deem
appropriate for the withholding of any taxes which it determines is required in
connection with any Options granted under the Plan.  The Corporation may further
require notification from the Optionees upon any disposition of Stock acquired
pursuant to the exercise of Options granted hereunder.

         18.  Code References and Definitions.  Whenever reference is made in
this Plan to a section of the Internal Revenue Code, the reference shall be to
said section as it is now in force or as it may hereafter be amended by any
amendment which is applicable to this Plan.  The term "subsidiary" shall have
the meaning given to the term "subsidiary corporation" by Section 425(f) of the
Internal Revenue Code.  The term "10% Holder" shall mean any person who, for
purposes of Section 422 of the Internal Revenue Code owns more than 10% of the
total combined voting power of all classes of stock of the employer corporation
or of any subsidiary corporation.

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

         The Company has adopted the 1997 Employee Stock Option Plan (the "1997
Plan"), permitting the grant of incentive stock options (within the meaning of
Section 422 of the Internal Revenue Code) to employees of the Company or its
subsidiaries or any parent corporation of the Company.  The Optionee, pursuant
to the 1997 Plan, is presently employed by the Company or one of its

         NOW, THEREFORE, in consideration of the premises and for other good
and valuable consideration, receipt of which is hereby acknowledged, the

    (b)  The Option granted hereby shall expire and terminate at 5:00 p.m.

         2.  EXERCISE PRICE.  The exercise price of the Option shall be 
_________ per Share, and shall be payable in cash or by certified check; 
provided, however, that in lieu of payment in full in cash or by such check, 
the exercise price (or balance thereof) may be paid in full or in part by the 
delivery and transfer to the Company of Shares already owned by the Optionee 
and having a fair market value (as determined by the Board of Directors in 
its absolute discretion) equal to the cash exercise price (or balance 
thereof) for the number of Shares as to which the Option is being exercised.  
The Company shall pay all original issue or transfer taxes on the exercise of 
the Option.

                                   -2-

<PAGE>

         3.  EXERCISE OF OPTION.  The Optionee shall notify the Company by 
registered or certified mail, return receipt requested, addressed to its 
principal office, as to the number of Shares which he desires to purchase 
under the Option, which notice shall be accompanied by payment of the Option 
exercise price therefor as specified in Paragraph 2 above.  As soon as 
practicable after the receipt of such notice, the Company shall, at its 
principal office or another mutually convenient location, tender to the 
Optionee certificates issued in the Optionee's name evidencing the Shares 
purchased by the Optionee hereunder.

         4.  CONDITIONS OF EXERCISE.

             (a)  The Optionee shall have the right to exercise the Option only
while he shall be in the full-time employ of the Company or any of its
subsidiaries, except that if the Optionee's employment shall be terminated for
any reason other than his death, the Option may be exercised at any time within
three (3) months after the date of termination but only to the extent that it
was exercisable upon such date of termination and in no event after the
Expiration Date.  If the Optionee shall have terminated his employment within
one year of the date of the grant of the Option, the Option shall immediately
terminate.
             (b)  If the Optionee shall die while in the employ of the Company
or any of its subsidiaries, this Option may be exercised, to the extent
exercisable on the date of the Optionee's death, by his executor, administrator
or other person at the time 


                                    -3-
<PAGE>

entitled by law to his rights under this Option, at any time within three (3)
months after such date of death, but in no event after the Expiration Date.

             (c)  Notwithstanding anything to the contrary contained herein,
the aggregate fair market value, determined at the time of option grant, of the
Shares with respect to which the Option, together with any other "incentive
stock option" within the meaning of Section 422 of the Internal Revenue Code
("ISO"), granted to the Optionee by the Company or any of its subsidiaries, may
be first exercised in any calendar year, cannot exceed $100,000 plus any "unused
carryover" from previous years.  For purposes of this Agreement, "unused
carryover" means the amount, computed separately for each calendar year, by
which $100,000 exceeds the fair market value (determined at the time of grant)
of all ISO's granted to the Optionee by the Company and its subsidiaries that
first became exercisable and were in fact exercised by the Optionee in such
year, reduced by the amount that such carryover may have been used in prior
calendar years.  

          5.  NON-ASSIGNABILITY OF OPTION.  The Optionee may not give, grant,
sell, exchange, transfer legal title, pledge, assign or otherwise encumber or
dispose of the Option herein granted or any interest therein, otherwise than by
will or the laws of descent and distribution and, except as provided in
Paragraph 4(b) hereof, the Option shall be exercisable only be the Optionee.

         6.  THE SHARES AS INVESTMENT.  By accepting the Option, the Optionee
agrees for himself, his heirs and legatees that any 

                                   -4-
<PAGE>

and all Shares purchased upon the exercise thereof shall be acquired for 
investment and not for distribution, and upon the issuance of any or all of 
the Shares subject to the Option, the Optionee, or his heirs or legatees 
receiving such Shares, shall deliver to the Company a representation in 
writing that such Shares are being acquired in good faith for investment and 
not for distribution. The Company may place a "stop transfer" order with 
respect to such Shares with its transfer agent and may place an appropriate 
restrictive legend on the certificate(s) evidencing such Shares.

         7.  RESTRICTION ON ISSUANCE OF SHARES.  The Optionee shall, if so
requested by the Company, represent and agree, in writing and in such form as
the Company shall determine, that any securities purchased by the Optionee upon
the exercise of this Option are being purchased for investment and not with a
view to the distribution thereof, and shall make such other or additional
representations and agreements and furnish such information as the Company may
in its reasonable discretion deem necessary or desirable to assure compliance by
the Company, on terms acceptable to the Company, with provisions of the
Securities Act of 1933 and any other applicable legal requirements.  If at any
time the Company shall reasonably determine that the listing, registration or
qualification of the Shares subject to this Option upon any securities exchange
or under any state or federal law, or the consent or approval of any
governmental regulatory body, are necessary or desirable in connection with the
issuance or purchase 

                                   -5-
<PAGE>

of the Shares subject thereto, this Option may not be exercised in whole or in
part unless such listing, registration, qualification, consent or approval shall
have been effected or obtained free of any conditions not acceptable to the
Company.  The Optionee shall have no rights against the Company if this Option
is not exercisable by virtue of the foregoing provision.  The certificate
representing any securities issued pursuant to the exercise of this Option may,
at the discretion of the Company, bear a legend in substantially the following
form:
                    "The securities represented by this certificate have not
          been registered under the Securities Act of 1933.  The securities 
          have been acquired for investment and may not be pledged or 
          hypothecated and may not be sold or transferred in the absence of 
          an effective Registration Statement for the securities under the 
          Securities Act of 1933 or an opinion of counsel to the Company that 
          registration is not required under said Act.  In the event that a
          Registration Statement becomes effective covering the securities or 
          counsel to the Company delivers a written opinion that registration 
          is not required under said Act, this certificate may be exchanged 
          for a certificate free from this legend."


         8.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION.

             (a)  In the event of changes in the outstanding Shares by reason 
of stock dividends, split-ups, recapitalizations, mergers, consolidations, 
combination, exchanges of shares, separations, reorganizations, liquidations 
and the like, the number of Shares issuable upon the exercise of the Option 
and the exercise price thereof shall be correspondingly adjusted by the 
Company.  No adjustment shall be made, however, with respect to stock 
dividends or splits which do not exceed 5% in any fiscal year, cash dividends 
or the issuance to the Company's shareholders of rights 

                                    -6-
<PAGE>

to subscribe for additional Shares or other securities.

             (b)  Any adjustment in the number of Shares shall 
apply proportionately to only the then unexercised portion of the Option.  If
fractional Shares would result from any such adjustment, the adjustment shall be
revised to the next higher whole number.

          9.  NO RIGHTS AS SHAREHOLDERS.  The Optionee shall have no rights as a
shareholder in respect of the Shares as to which the Option shall not have been
exercised and payment made as herein provided.

         10.  EFFECT UPON EMPLOYMENT.  This agreement does not give nor shall it
be construed as giving the Optionee any right to continued employment by the
Company or any of it subsidiaries.

        11.  CONFLICT BETWEEN OPTION AGREEMENT AND 1997 PLAN.  In the event
there are any conflicts between this Agreement and the terms and conditions of
the 1997 Plan, the terms and conditions of the 1997 Plan shall control.

        12.  BINDING EFFECT.  Except as herein otherwise expressly provided,
this Agreement shall be binding upon and shall inure to the benefit of the
parties hereto, their legal representatives and assigns.

        13.  GOVERNING LAW.  This agreement shall be governed by and construed
in accordance with the laws of the State of New Jersey applicable to agreements
made and to be performed wholly within the State of New Jersey.

                                    -7-

recording the Company's complete ownership and title thereto, and to cooperate
otherwise in all proceedings and matters relating thereto.

authentic accounts, notes, data and records of all the Inventions in the manner
and form registered by the Company. Such accounts, notes, data and records shall

indirectly, alone or with others, individually or through or by a corporate or
other business entity in which he may be interested as a partner, shareholder,

participate in, lend his name to, or render services to or for any business

affiliates shall include only the design, manufacture, marketing, sale, or

                    FIRST AMENDMENT TO DISTRIBUTION AGREEMENT
                   OLYMPUS AMERICA INC. AND CARSEN GROUP INC.

FIRST AMENDMENT ("Amendment") to Distribution Agreement ("Agreement") between
Olympus America Inc., a New York, U.S.A. corporation having its principal office
at Two Corporate Center Drive, Melville, New York, U.S.A. 11747-3157, and Carsen
Group Inc., a Canadian corporation having its principal office at 151 Telson
Road, Markham, Ontario, Canada L3R 1E7. Capitalized terms used but not otherwise
defined in this Amendment shall have the meanings ascribed to such terms in the
Agreement.

WHEREAS, Olympus and Carsen entered into the Agreement as of April 1, 1994;

WHEREAS, Olympus and Carsen wish to extend the Term and otherwise amend the
Agreement as is hereinafter set forth;

NOW, THEREFORE, for good and adequate consideration, receipt of which is hereby
acknowledged, the parties hereby agree as follows:

1. In the introductory paragraph and Section 10.4 (Notices), Olympus's address
is deleted and replaced with:

                   Two Corporate Center Drive 
                   Melville, New York, U.S.A. 11747-3157

2. In Section 10.4 (Notices), Olympus's name shall be corrected to read:

                   Olympus America Inc.

3. Delete the text of Section 2.2 and replace it with the following:

       "2.2 Consumer Products. Notwithstanding anything to the contrary
       contained in Section 2.1 or elsewhere in this Agreement, (a) Olympus may
       sell and service Consumer Products to and for Consumer Product retailers
       with locations in the Territory but that are based in the United States
       ("U.S.-Based Retailers"), (b) Olympus shall be involved in the primary
       planning, presentations, and negotiations to and with U.S.-Based
       Retailers, (c) Olympus will use commercially reasonable efforts, based on
       Olympus's evaluation of the particular circumstances, to promote to
       U.S.-Based Retailers the purchase of Consumer Products within the
       Territory from Carsen, and (d) Olympus will be involved in the primary
       planning, presentations, and negotiations to and with Consumer Product
       retailers with locations in the United States but that are based in the
       Territory."

4. Delete the third sentence of Section 5.3.3 and replace it with the following:

       "Notwithstanding the foregoing, should Carsen default with respect to the
       Minimum Dollar Purchase Requirements for (a) both Industrial Products and
       Precision Products, and/or (b) Medical Products, Olympus may terminate
       this Agreement with respect to any

<PAGE>

       such grouping or group or, in the alternative, terminate the entire
       Agreement, upon thirty (30) days' notice within six (6) months of such
       default."

5.3.4, insert the word "Dollar" after the word "Minimum".

6. In Sections 5.3.2, 5.3.3, 5.3.4, and 5.4.6, all references to "Product group"

sub-group within the Consumer Products group. As an example only, if Carsen
achieves Minimum Dollar Purchase Requirement for Photo & Binocular Consumer
Products but fails to achieve the Minimum Dollar Purchase Requirement for Audio
Consumer Products, Olympus will be entitled to either terminate the Agreement
with respect to Audio Consumer Products only or make any other alternative
distribution arrangement with respect to Audio Consumer Products only.

7. In Section 9.1.1 (Term), the Term will be extended by thirty-six (36) months,
and the Term will expire, unless terminated earlier in accordance with the terms
of the Agreement, on March 31, 2001.

8. Schedules 1.5, 1.6, 1.8, 1.9, and 5.3 are removed and replaced with the
respective revised schedules attached to this Amendment.

9. During the period commencing as of the date of this Amendment and ending on

which the sale, distribution, marketing, promotion, advertising, leasing, and
servicing of digital camera, optical storage, and other computer peripheral
Consumer Products shall be treated under the Agreement. The mutually agreed-
upon results of such discussions shall be reflected in a further amendment to
the Agreement.

10. Except as modified by this Amendment, the Agreement remains in full force
and effect.


IN WITNESS WHEREOF, the parties have executed this Amendment to the Agreement as
