     When we use the terms "Company", "Sybron", "we" or "our" in this report, we
are referring to Sybron International Corporation and its subsidiaries and their
respective predecessors. Our fiscal year ends on September 30. All references to
"1994", "1995", "1996", "1997" or "1998" mean the fiscal year ended September
30, 1994, 1995, 1996, 1997 or 1998, respectively. All references to shares,
stock prices and earnings per share have been adjusted to reflect Sybron's
two-for-one stock splits effected on December 15, 1995, and February 20, 1998,
and our adoption of Statement of Financial Accounting Standards No. 128
"Earnings per Share". In April 1998 we completed a merger with LRS Acquisition
Corp. ("LRS") which was accounted for as a pooling of interests. Unless
otherwise stated, all financial data reported in 1995, 1996, 1997 and 1998 has
been restated to reflect the combined companies as if the transaction took place
on October 1, 1994, the first full year of LRS' operations.

                              HISTORY AND STRATEGY
 
     Sybron International Corporation is a Wisconsin corporation, incorporated
in 1993 to be the successor by merger in January of 1994 to Sybron Corporation,
a Delaware corporation. The merger was accomplished to change Sybron's corporate
domicile from Delaware to Wisconsin. The Delaware Sybron Corporation, originally
named Sybron Acquisition Company, was formed in 1987 to acquire all of the
outstanding shares of a company known at the time as Sybron Corporation in a
leveraged buyout (the "Acquisition").
 
     In 1986, when the previous Sybron was taken private in a leveraged buyout,
we initiated programs to reduce corporate and subsidiary expenses, rationalize
production facilities and sell certain operating businesses. The Company was
then resold in the Acquisition. After the Acquisition, we focused on maximizing
cash flow in order to repay debt incurred in connection with the Acquisition. In
1992, we went public and the proceeds of our initial public offering (the "IPO")
were used to retire a portion of the debt incurred in connection with the
Acquisition (the "Acquisition Debt"). We refinanced the balance of the
Acquisition Debt in 1993 when we put in place a bank credit facility, which also
provided us with a line of credit designed to allow the initiation of an
acquisition program. This line of credit was amended in 1995, 1997 and 1998 to
accommodate the growth of our acquisition program. See Note 7 to our
consolidated financial statements in Item 8 of this Annual Report. Our
acquisition program, together with the operating strategies we have executed
consistently since the 1986 buyout, are designed to expand and strengthen our
worldwide sales and profitability. Key elements of our strategy are:
 
          Competitive Focus.  We are focused on product development and
     manufacturing and marketing efforts, increasing our range of specialty and
     value-added laboratory, dental and orthodontic products and increasing the
     range of end users for our products.
 
          Acquisitions.  Since 1993, when we adopted our strategy of growth
     through acquisitions, we have made more than 60 acquisitions (including
     three mergers and a joint venture) in the United States and abroad,
     including 22 completed in 1998 and three in fiscal 1999 through December 1,
     1998. See Note 14 to our consolidated financial statements in Item 8 of
     this Annual Report. Our operating subsidiaries have been able to use their
     existing distribution channels to market many of the acquired product
     lines. We have achieved other synergies, such as the elimination of
     duplicative administrative functions or the combining of manufacturing
     operations, with some of these acquisitions.
 
          New Product Introductions.  Our operating subsidiaries have
     consistently developed and introduced new products which have contributed
     to net sales. We believe that new product introductions are important to
     the ability of our operating subsidiaries to maintain their competitive
     positions.
 
          International Growth.  We have devoted significant resources to
     international manufacturing, sales and marketing efforts in order to
     capitalize on foreign sales opportunities. As a result of our efforts,
     sales outside the United States have grown from $75.2 million in the twelve
     months ended September 30, 1987 to $292.1 million in 1998. In 1996, 1997
     and 1998, sales outside the United States represented approximately 36%,
     33% and 30%, of our net sales, respectively. The steady decrease in the
     percentage of foreign sales is primarily due to acquisitions, which have
     been predominantly in the United States, a general strengthening of the
     U.S. dollar in 1997 and 1998, and a weakening Asian market in 1998. See
     Item 7, "Management's Discussion and Analysis of Financial Condition and
     Results of Operations."
 
     The successful execution of the various elements of our strategy resulted
in a significant expansion of the business in 1998. Overall sales growth in 1998
was $121.7 million, or $133.4 million prior to negative foreign currency
effects. Internal sales growth, prior to $11.7 million of negative currency
effects, was $18.5 million (up 2.3% from 1997). Acquisition growth has been more
significant for SLPC than SDS because the worldwide market for laboratory
products is substantially larger than that for dental products. Net sales in the
laboratory segment as a percentage of our total net sales were 55.1%, 58.5% and
63.0% in 1996, 1997 and 1998, respectively. We intend to pursue our acquisition
strategy at both SLPC and SDS but, due to the disproportionate size of these
markets, we expect to see more opportunity for growth at SLPC. In addition to
the growth contributed from acquired businesses, we have been able to realize
cost benefits derived from the elimination of duplicative costs in
administrative and manufacturing areas.

BUSINESSES AND PRODUCTS OF SYBRON LABORATORY PRODUCTS CORPORATION
 
                                    GENERAL
 
     In May 1998 we realigned our laboratory subsidiaries under SLPC. We did
this in order to take advantage of sales, marketing, administrative and
manufacturing synergies among companies which have related product lines,
customers and methods of distribution. Headquartered in Portsmouth, New
Hampshire, SLPC is responsible for managing subsidiaries in four product
categories. The categories are i) Labware and Life Sciences, ii) Clinical and
Industrial Technologies, iii) Diagnostics and Microbiology and iv) Laboratory
Equipment. Products in these categories bear brand names such as NALGENE(R),
NUNC(R), BARNSTEAD(R), THERMOLYNE(R), REMEL(R), SUPERFROST(R) and COLORFROST(R),
which are well recognized in the laboratory industry.

                                    PRODUCTS
 
     LABWARE AND LIFE SCIENCES.  Our labware products include approximately
4,900 items, including reusable plastic products (bottles, carboys, graduated
ware, beakers and flasks) and disposable plastic products (microfiltration and
cryogenic storage products). Other labware products include products for
critical packaging applications (bottles for packaging diagnostic reagents,
media and specialty chemicals), safety products (hazard labeled containers and
biohazard disposal products), environmental containers, and autosampler vials
and seals used in chromatography analysis. Life sciences products include
applications of cell culture, filtration, molecular biology, cryopreservation,
immunology and electrophoresis technologies.
 
     Labware products are primarily manufactured at Nalge Nunc International
Corporation ("NNI"). NNI's NALGENE(R) brand laboratory products are typically
sold at prices ranging from $5 to $1,000 to general, industrial and research
laboratories. In general, these products are designed to offer the scientist or
laboratory technician a safer, less expensive and more durable alternative to
labware products made of glass or other materials. NNI also manufactures a line
of popular consumer products such as bicycle bottles and recreation containers
for camping and hiking.
 
     We have expanded the breadth of our product offerings in labware through
our acquisition program. In fiscal 1993, NNI added its line of environmental
containers with the purchase of I-CHEM Research Inc., and in 1997 it added,
through a merger with National Scientific Company, autosampler vials and seals
and accessories used in chromatography analysis. We broadened our participation
in the Life Sciences area in 1995 through the purchase of Owl Scientific, Inc.
("Owl"), a manufacturer of electrophoresis equipment used in molecular biology.
In 1997 we strengthened the electrophoresis product line by purchasing
Integrated Separation Systems ("ISS"), and then combined Owl and ISS to form Owl
Separation Systems, Inc. In July 1995 we acquired the Nunc group of companies,
manufacturers of plastic labware used in research applications such as cell
culture, molecular biology, cryopreservation and immunology. In 1997 NNI formed
a joint venture with the owner of the Japanese distributor of Nunc's products by
acquiring 75% of the stock of Nippon InterMed K.K. In 1998, we acquired Lida
Manufacturing Corporation, a manufacturer of syringe filters for chromatography
sample preparation, biological research, genetic research, and general
laboratory filtration, and Summit Biotechnology, Inc., which processes and sells
fetal bovine serum for cell culture and diagnostic purposes. In October 1998
(fiscal 1999), we acquired Invitro Scientific Products, Inc., a producer of
roller bottles and packaging containers used in biological production facilities
to manufacture vaccines, pharmaceuticals, and other reagents.
 
     Labware and Life Sciences accounted for approximately 28%, 25% and 24%, of
our consolidated net sales in 1996, 1997 and 1998, respectively.
 
     CLINICAL AND INDUSTRIAL TECHNOLOGIES.  Clinical and Industrial Technologies
products include microscope slides, cover glass, glass tubes and vials, stains
and reagents for clinical testing, thin glass for watch crystals, cosmetic
mirrors, and precision and coated glass used in various optic applications. Also
included are process technologies products such as plastic tubing and tanks,
silicone tubing and non-metallic fittings for the pharmaceutical, semi-conductor
and biotechnology industries, pipe and tubing for ultra-pure applications,
hoses, fittings and accessories used in fluid and gas transport applications and
sanitary stainless steel fittings used in such applications.
 
     Our first products in this category were plain microscope slides and cover
glass, manufactured by Erie Scientific Company ("Erie"). Erie expanded this
product line through the addition of value-added slides with special printing
and coatings to help lab technicians be more efficient and for specialty
applications. Value-added products include SUPERFROST(R) and COLORFROST(R) brand
printed slides, which provide an indelible marking surface and are disposable;
SUPERFROST(R)Plus adhesion slides, disposable slides which are electrically
charged in a way which causes cells to adhere to them; and disposable and
reusable diagnostic slides which are custom designed and printed to customer
specifications for use in diagnostic test kits. We added stains and fixatives
for use in histology laboratories to this product category when we acquired
Richard-Allan Scientific Company in 1995 and Stephens Scientific, Inc. in 1996.
In 1995 we added consumable histology products, such as tissue cassettes used
for biopsies, through the acquisition of the Secure Medical Products product
line. In 1996 we acquired The Naugatuck Glass Company, a manufacturer of thin
glass
                                        4
<PAGE>   8
 
mirrors used in the cosmetic industry, and precision and coated glass used in
optics applications. A significant disposable laboratory glassware business was
added to this product category in 1998 with the acquisition of Chase Instruments
Corp., and Chase's subsequent addition of related products through its
acquisition of SciCan Scientific and Scherf Prazision GmbH later in the same
year. Also in 1998, we acquired Cel-Line Associates, Inc., a manufacturer of
printed microscope slides and Naugatuck acquired Marks Polarized Corporation, a
manufacturer of laminated filters, polarizers and optical products. More
recently, in October 1998 (fiscal 1999), we acquired Samco Scientific
Corporation, a manufacturer of transfer pipettes and specimen containers.
Beginning in 1995, through a series of acquisitions, we added process technology
products. In February 1995 we acquired Sani-Tech, Inc. In 1996, we broadened our
product line through the acquisitions of Acutech Plastics, Inc. and Flexible
Components, Inc. In 1997 we added Pure-Fit, Inc. These companies were combined
in 1998 to form Nalge Process Technologies Group, Inc.
 
     Clinical and Industrial Technologies products accounted for approximately
17%, 19% and 19%, of our consolidated net sales in 1996, 1997 and 1998,
respectively.
 
     DIAGNOSTICS AND MICROBIOLOGY.  Our Diagnostics and Microbiology products
are used for drug testing, therapeutic drug monitoring, infectious disease
detection, pregnancy testing, glucose tolerance testing, blood bank saline
testing, clinical diagnostic liquid standards and research application
temperature measurement. Products include diagnostic test kits, culture media,
diagnostic reagents, and other products used in detecting causes of various
infections or diseases.
 
     Our participation in these areas evolved through a series of diagnostic
company acquisitions beginning in 1995 with the purchase of Ever Ready
Thermometer Co., Inc. ("Ever Ready"). Ever Ready is a manufacturer of high
quality precision thermometers, hydrometers and temperature calibration
equipment. Later in 1995 we acquired New England Reagent Laboratory, Inc.
("NERL"), a manufacturer of liquid standards and reagents used with clinical
diagnostics and testing equipment. NERL was later combined with CASCO Standards,
Inc. ("CASCO") to form CASCO-NERL Diagnostics Corporation. CASCO, a 1996
acquisition, is a manufacturer of liquid standards as well as calibration
verification and quality control materials used with clinical diagnostic and
testing equipment. In 1997 we added drug-screening products with the acquisition
of Drug Screening Systems, Inc. and began to expand in microbiology through the
purchase of Trend Scientific, Inc. and Alexon Biomedical, Inc. These companies
have been combined to form Alexon-Trend, Inc., a manufacturer of test kits used
to detect a variety of parasitic, bacterial and viral causes of infections. We
became a significant manufacturer of microbiology products, including plated and
tubed media, with the 1997 acquisition of Remel Limited Partnership. We added to
the Remel business by acquiring Carr-Scarborough Microbiologicals, Inc. in the
same year, and Clinical Standards Labs, Inc., DiMed Corporation and MicroBio
Products, Inc. in 1998. Also in 1998, we acquired the diagnostic products of
Seradyn, Inc. a manufacturer of infectious disease diagnostic reagents and test
kits, as well as uniform latex particles used in the production of diagnostic
reagents. Additional diagnostic companies added in 1998 include Diagnostic
Reagents, Inc., a manufacturer of immunoassay reagents used principally for
drugs of abuse testing, Criterion Sciences, a manufacturer of a glucose
tolerance beverage, hematology stains, reagents and other solutions used in
laboratory analysis and testing, Custom Laboratories, Inc., a manufacturer of a
glucose tolerance test beverage and Applied BioTech, Inc., a manufacturer of
test kits for rapid detection of pregnancy, drugs of abuse and infectious
diseases.
 
     Diagnostic and Microbiology products accounted for approximately 2%, 6% and
12% of our consolidated net sales in 1996, 1997 and 1998, respectively.
 
     LABORATORY EQUIPMENT.  Our Laboratory Equipment products include i)
heating, stirring and temperature control apparatus such as hot plates,
stirrers, shakers, heating tapes, muffle furnaces, incubators, dri-baths, bench
top sterilizers and cryogenic storage apparatus, which are fundamental to basic
procedures performed in the laboratory, ii) systems for producing ultra pure
water, iii) bottle top dispensers, positive displacement micropipettors, and
small mixers used in biomolecular research, iv) constant temperature equipment
including refrigerators/freezers, ovens, water baths, environmental chambers,
and furnaces and v) fluorometers, spectrophotometers, and strip chart recorders.
 
                                        5
<PAGE>   9
 
     Laboratory equipment is manufactured at Barnstead Thermolyne Corporation
("Barnstead Thermolyne") and its subsidiaries. BARNSTEAD(R) brand products are
used to produce ultra pure water, the most common laboratory reagent. Because
the water purity requirements of end-users differ, Barnstead Thermolyne offers
distillation, deionization, reverse osmosis, ultraviolet oxidation, and
absorption or filtration technologies for purifying water. THERMOLYNE(R) brand
products include heating, stirring and temperature control apparatus that are
fundamental to basic procedures performed in the laboratory. Both BARNSTEAD(R)
and THERMOLYNE(R) brand products are typically priced between $100 and $5,000.
 
     Barnstead Thermolyne has added to its product line from time to time
through acquisitions. In 1994 it added bottle top dispensers, positive
displacement micropipettors, and small mixers used in biomolecular research
through the acquisition of Labindustries, Inc. In 1995 it added PMC(R) brand
programmable hotplate/ stirrers, TURNER(R) brand fluorometers and
spectrophotometers, and LINEAR(R) brand strip chart recorders through the
acquisition of Biomolecular, Inc. In 1997 it acquired the HARVEY(R) bench top
sterilizer business. In 1998 it acquired Electrothermal Engineering, Ltd., a
manufacturer of heating mantles and controls, and Lab-Line Instruments, Inc.,
which manufactures constant temperature equipment including shakers,
refrigerators/freezers, ovens, water baths, environmental chambers, and
furnaces.
 
     Laboratory equipment accounted for approximately 9%, 8% and 8% of our
consolidated net sales in 1996, 1997 and 1998, respectively.
 
                                  NEW PRODUCTS
 
     Apart from the addition of new products through its acquisition program,
product development efforts at SLPC and its subsidiaries are focused on
expanding product offerings in the laboratory markets currently served. Product
offerings are designed to develop and improve products for new and existing
technologies and to allow laboratories and lab technicians to take cost out of
their procedures. Recent examples of new products from the Labware and Life
Sciences category include P.E.T. packaging and laboratory bottles, Nunc EZ cell
culture flasks, Cantene outdoor bottles, micro-packaging vials and low
particulate bottles. New products from the Clinical and Industrial Technologies
category include EDGE-RITE(R) microtome blades, pre-filled specimen containers,
SUPERSLIP(R) cover glass, COLORMARK(R) slides, convoluted FEP hose and silicon
double Y tubing for parastaltic fluid monitoring. New Diagnostic and
Microbiology products include Campobacter, Rotovirus and Adnovirus tests. New
Laboratory Equipment products in 1998 include ROPURE INFINITY(R), a reverse
osmosis water purification system, European test tube incubators and an extended
safety hot plate stirring line. We spent approximately $6.8, $7.9 and $8.8
million on research and development in the laboratory segment in 1996, 1997 and
1998, respectively.
 
                             MARKETS; DISTRIBUTION
 
     We estimate that the worldwide laboratory market includes more than 150,000
industrial, academic, clinical, governmental and biotechnology laboratories. A
large portion of our laboratory products are sold through approximately 10
domestic and 15 international distributors. Three (primarily domestic)
distributors, Fisher Scientific ("Fisher"), VWR Scientific ("VWR"), and
Allegiance Corporation ("Allegiance"), accounted in aggregate for approximately
45%, 34% and 31% of our laboratory subsidiaries' sales in 1996, 1997 and 1998,
respectively. Laboratory supply distributors offer a wide variety of supplies,
apparatus and instruments for the laboratory, primarily through catalogs. End
users rely heavily on these catalogs in identifying suitable products and making
purchase decisions, and the amount of catalog space provided and the number of
product items listed for a particular vendor are critical marketing variables.
We believe the number of SLPC products offered by the major distributors is
among the highest of any of SLPC's competitors.
 
     SLPC's products are sold using a variety of methods, including dealer
distribution, direct sales, and private labeling. For example, the drugs of
abuse testing products of Diagnostic Reagents, Inc. are sold to manufacturers of
automated testing equipment and to a limited extent through distribution, while
the microbiology products of Remel Inc. are primarily sold directly to the end
user through Remel's own national distribution system. Packaging products are
sold primarily through distributors, and plastic consumer products
 
                                        6
<PAGE>   10
 
are sold directly to retailers. Most of SLPC's subsidiaries maintain their own
sales forces, whether they sell directly to end users, through distribution or
otherwise. The combined sales forces include approximately 171 domestic and 33
international sales people.
 
                                 INTERNATIONAL
 
     In addition to an extensive distributor network, SLPC subsidiaries maintain
both sales offices and manufacturing plants in international locations. Foreign
sales offices are located in the United Kingdom, Germany and Japan.
International manufacturing facilities include Nunc A/S, a manufacturer of life
sciences products, located in Denmark; Gerhard Menzel Glasbearbeitungswerk GmbH
& Co. K.G., a manufacturer of microscope slides, located in Germany; Erie
Electroverre S.A., a manufacturer of thin white glass, located in Switzerland;
Erie Scientific Kft, a manufacturer of microscope slides, located in Hungary;
and Erie-Watala Glass Co. Ltd., a joint venture, which produces cut glass for
the watch crystal industry, located in Hong Kong. Foreign sales of laboratory
products accounted for approximately 16%, 14% and 15% of our consolidated net
sales in 1996, 1997 and 1998, respectively.
 
                                  COMPETITION
 
     We believe that the principal competitive advantages of SLPC and its
subsidiaries include their ability to define specific customer needs and to
develop products to address those needs, the breadth and depth of their product
lines, significant brand recognition, the economics associated with vertical
integration in certain product lines, their long term relationships with the key
industry distributors and, in several of their lines of business, expertise in
plastic molding technology. Although there are a number of competitors in SLPC's
individual product lines, we believe that no competitor offers a mix of product
lines or depth within individual product lines comparable to SLPC.
 
     Our principal competitors for Labware and Life Sciences products are
Corning/Costar, Millipore Corporation, Wheaton Science Products, and Kautex
Werke Reinhold Hagen A.G. Principal competitors in the Clinical and Industrial
Technologies category include Shandon (a division of Life Sciences, Inc.),
Knittel Glaser, Surgipath Medical Industries, Inc., Sigma-Aldrich Company, Copan
Diagnostics Company, Elkay Products, Inc., American Precision Plastics and Star
Plex Corporation. Becton Dickinson Microbiology Systems, Meridian Diagnostics
International, Biokit, SA, Dyno Particles AS and Abbott Laboratories are our
principal competitors with respect to Diagnostic and Microbiology products.
Principal competitors in the Laboratory Equipment category are Corning Costar,
Inc. ("Corning/Costar"), Millipore Corporation, New Brunswick Scientific

Signal Corp.).
 
BUSINESSES AND PRODUCTS OF SYBRON DENTAL SPECIALTIES, INC.
 
                                    GENERAL
 
     SDS, located in Orange, California, was organized in 1993 when we grouped
our Professional Dental and Orthodontic companies, Kerr Corporation ("Kerr") and
Ormco Corporation ("Ormco"), under the SDS umbrella. The subsidiaries of SDS
market their products under brand names such as KERR(R), belle de st. claire(R),
Metrex(R), ORMCO(R) and "A" Company Orthodontics(R), which are well recognized
in the dental and orthodontic industries.
 
                                    PRODUCTS
 
     PROFESSIONAL DENTAL.  Our Professional Dental products include light cured
composite filling materials and bonding agents, amalgam alloy filling materials,
dental burs, impression materials, and curing lights used in general dentistry,
filling materials and sealers used in endodontics, waxes, specialty burs,
investment and casting materials, equipment and accessories used in dental

                                        7
<PAGE>   11
 
     Our light cured composite and amalgam alloy filling materials are used
primarily for filling cavities. Both composite and amalgam alloy filling
materials are manufactured by Kerr. Kerr added to its array of composite filling
materials with the acquisition of E&D Dental Products, Inc. in 1996. Dental burs
are the cutting instruments attached to dentists' drills and used to prepare the
tooth for treatment. Our dental burs are primarily manufactured at Beavers
Dental Company. We added to this product line in 1997 with the purchase of
Precision Rotary Instruments, a manufacturer of diamond dental burs.
 
     Kerr manufactures impression materials, used to make replicas of dentition,
and has broadened this line of product by developing new product delivery
features and advance materials. Kerr's XP(TM) Putty and MPV(TM) (Multi Purpose
Viscosity), are both examples of advancements in materials and delivery features
which have significantly contributed to sales.
 
     Curing lights are lights used by the dentist to cure composite filling
materials after the composite has been applied to a patient's tooth. We entered
the curing light business with the purchase of Demetron Inc. in 1994.
 
     Endodontic products include instruments, filling materials, sealers,
microscopic endodontic instruments and equipment primarily used in root canal
treatment. Endodontic instruments are primarily manufactured at Kerr. We
enhanced our product lines in the endodontic equipment business in 1995 with the
purchase of Analytic Technology Corporation, and entered the microscopic
endodontic instrument and technique business with the purchase of Excellence in
Endodontics, Inc. in 1996. We enhanced our endodontic instrument line in 1998
with the purchase of the Tycom Dental Corporation. We enhanced our dental
laboratory product line with the acquisition of belle de st. claire inc. in
1996.
 
     Infection control products include high level disinfectants and sterilants,
and enzymatic cleaners and soakers for medical and dental instruments, surface
disinfectant products for medical and dental offices, and skin cleansers for
medical and dental use. These products are manufactured or supplied by Metrex
Research Corporation, acquired in 1995. Metrex expanded its product line through
the acquisition of Micro-Aseptic Products, Inc. (a supplier of disinfectants,
deodorizers, antiseptic hand and skin cleansers) in 1996 and Viro Research
International, Inc. (a supplier of skin antisepsis products) in 1998, and
through the acquisition of the high level disinfectant/sterilant business of
Cottrell Ltd. in 1998.
 
     Professional Dental products accounted for approximately 24%, 23% and 20%
of our consolidated net sales in 1996, 1997 and 1998, respectively.
 
     ORTHODONTICS.  Our orthodontic products include a broad range of
orthodontic appliances such as brackets, bands and buccal tubes, wires and
elastomeric products. Brackets, bands, buccal tubes and wires are manufactured
from a variety of metals to exacting specifications for standard use or to meet
the custom specifications of a particular orthodontist. Elastomeric orthodontic
products include rubberbands and power chains to consolidate space. Products in
this area also include orthodontic instruments and general orthodontic supply
products. These products have historically been manufactured and marketed by
Ormco. Ormco expanded its orthodontic product line through the acquisition of
E.T.M. Corporation (a manufacturer of orthodontic hand instruments) and Allesee
Orthodontic Appliances, Inc. (a manufacturer of custom-made positioners,
retainers and other accessories) in 1994. In 1998, we significantly enhanced the
orthodontic line through our merger with LRS Acquisition Corp., the parent of
"A" Company Orthodontics, which is a manufacturer and developer of brackets,
archwires and related products.
 
     Orthodontic products accounted for approximately 21%, 19% and 17%, of our
consolidated net sales in 1996, 1997 and 1998, respectively.
 
                                  NEW PRODUCTS
 
     The subsidiaries of SDS devote considerable resources to the development
and introduction of new products. These efforts are critical to meeting the
needs of today's dentists and orthodontists. In the professional dental supply
industry product development requires diverse technical expertise and knowledge
of various market trends, which SDS and its subsidiaries possess. Kerr takes
advantage of its expertise and knowledge by working closely with dentists to
develop new and improved products. Recently introduced
                                        8
<PAGE>   12
 
products such as belleGlass HP(TM) (an indirect restorative composite),
Temphase(TM) (a temporary crown and bridge material) and OptiBond Solo(TM) (a
composite adhesive in unit doses) have significantly contributed to Kerr's net
sales. In the orthodontic industry, Ormco's sales force maintains direct contact
with orthodontists to identify market trends. Ormco works closely with
orthodontists to improve existing products and develop new products primarily
through its Champion program in which selected orthodontists assist Ormco in
designing, developing and ultimately educating users on new product and
technique innovations. In recent years, Ormco has introduced a number of new
products which have contributed significantly to it's sales. Examples of
recently introduced products include the Twinlock(TM) self-ligation appliance
system, the Bitefixer(TM) Class II correction device, and the Enlight(TM)
light-cured adhesive.
 
     We spent approximately $8.4 million, $7.9 million and $7.3 million on
research and development in the professional dental and orthodontic product
categories in 1996, 1997 and 1998, respectively.
 
                             MARKETS; DISTRIBUTION
 
     Professional Dental products are sold both domestically and internationally
through dental distributors. Kerr has 42 sales representatives in the United
States and 50 abroad dedicated to dental sales. Infection control products are
also sold into the medical market through a nationwide group of independent
manufacturer representatives who sell through dealers to end users. The mission
of the dental sales force and the independent manufacturer representatives is to
provide training and technical support to dealers and help pull products through
the dealer network.
 
     We expect modest growth in the domestic market for traditional dental
consumables; this should augment the demand for new products that make the
dentist more efficient. Kerr and our other dental companies are committed to
growing market share through product development and promotional activities. We
also believe opportunities for growth exist in international markets. As
economies in emerging markets of Eastern Europe, South America and the Far East
continue to develop, their demand for dental products will grow. Kerr is well
positioned to take advantage of such development due to its extensive experience
in selling internationally and the quality of its existing international dealer
network.
 
     Orthodontic products are marketed by approximately 66 direct salespersons
in the United States, Canada, Australia, Germany, Japan, Mexico, New Zealand and
The Netherlands (which replaced Switzerland as part of our restructuring in the
third quarter of 1998), and by dealers and distributors in other parts of the
world. Ormco's direct sales force, dealers and distributors are supported by
trade journal advertising, trade shows, seminars and telemarketing.
 
     Although the market for traditional orthodontic products is relatively
mature domestically, the market is experiencing growth in the adolescent
segment. We believe that the international market for orthodontic products
presents a significant growth opportunity as worldwide awareness of dental
aesthetics grows. As with other healthcare markets, over the past few years the
orthodontic market has experienced a consolidation of provider practices and the
formation of management organizations and buying groups, which are intended to
bring administrative efficiencies and buying power to orthodontic practices. We
believe Ormco is well positioned to compete in this environment because its
marketing philosophy is geared toward making orthodontic practices more
efficient through product innovation and customer service.
 
                                 INTERNATIONAL
 
     In addition to the United States, our Professional Dental products are
manufactured at facilities in Canada, Italy and Mexico. These products are sold
internationally through dealers, supported by sales offices in Europe, including
major offices in the U.K., France, Germany, Japan, Australia, South America and
Mexico.
 
     Prior to 1998, our Orthodontic products were sold directly to end users by
Ormco's sales force located in Australia, New Zealand, Canada, Germany,
Switzerland, Japan and Mexico. Ormco also had exclusive distributors in key
European markets such as Italy, France and Spain. In 1998, Ormco acquired its
distributor in France, the Ormodent group of companies, and now services the
French market directly. In addition, with
 
                                        9
<PAGE>   13
 
the "A" Company merger, European countries previously serviced from Ormco's
Swiss sales office will now be serviced from The Netherlands.
 
     Sales of Professional Dental products and Orthodontic products outside the
United States represented approximately 20%, 18% and 16% of our consolidated net
sales for 1996, 1997 and 1998, respectively.
 
                                  COMPETITION
 
     We believe that in Professional Dental products, our principal competitive
advantages include the breadth of our product lines, brand name recognition, and
our programs to educate the dentist regarding techniques and products. Our
principal competitors are GC America, Inc., 3M Corporation, Dentsply
International Inc., Espe GmbH & Co., and Ivoclar. In Orthodontics, we compete
with over 25 companies in the United States. We compete primarily on the basis
of product quality, the level of customer service, price and new product
offerings. Our competitors include American Orthodontics, GAC Orthodontics, and
Unitek (owned by 3M Corporation).
 
COMPETITION
 
     As we have described above, numerous competitors participate in our
laboratory, dental and orthodontic industries, a number of which have
substantially greater financial and other resources than ours. There can be no
assurance that we will not encounter increased competition in the future.
 
BACKLOG
 
     Our total backlog orders at September 30, 1996, 1997 and 1998 were
approximately $26.7 million, $36.3 million and $44.5 million, respectively. We
expect all September 30, 1998 backlog orders to be filled in fiscal 1999.
 
RESEARCH AND DEVELOPMENT
 
     We have a number of research and development programs in our various
businesses, and we consider them to be of importance in maintaining our market
positions. We spent approximately $15.2 million, $15.8 million and $16.1
million, on research and development in 1996, 1997 and 1998, respectively.
 
EMPLOYEES
 
     Our companies employed approximately 7,900 people at September 30, 1998,
approximately 543 of which are covered by collective bargaining agreements. We
believe our employee relations are generally good. In the United States, Kerr's
140 hourly employees at the Romulus, Michigan facility are members of the UAW.,
Barnstead Thermolyne's 233 hourly employees are members of the International
Brotherhood of Electrical Workers, NNI's 148 hourly employees at its Naperville,
Illinois facility are members of the International Brotherhood of Teamsters, and
Ever Ready Thermometer Co. Inc.'s ("Ever Ready") 22 hourly employees at its West
Paterson, New Jersey facility are members of the United Furniture Workers Union.
The labor contracts at Kerr, Barnstead Thermolyne, NNI and Ever Ready will
expire on January 31, 2002, March 1, 1999, December 20, 1998, and December 31,
1998, respectively. Many of our non-management employees in Europe are subject
to national labor contracts which are negotiated from time to time at the
national level between the national labor union and an employees' council. Once
national contracts are set, further negotiation can take place at the local
level. Such negotiations can affect local operations. Our Danish subsidiary,
Nunc A/S, was closed during the third quarter of 1998 for nine days as the
result of the first national strike in Denmark since 1985. After the national
strike was settled, Nunc A/S non-management employees struck for two days over
local issues. All issues have been resolved with a new contract through March
2000.

PATENTS, TRADEMARKS AND LICENSES
 
     Our subsidiaries' products are sold under a variety of trademarks and trade
names. They own all of the trademarks and trade names we believe to be material
to the operation of their businesses, including the KERR(R) trademark, the
NALGE(R) and NALGENE(R) trademarks, the NUNC(TM) and NUNCLON(R) trademarks,
Erie's SUPERFROST(R) and COLORFROST(R) trademarks, the THERMOLYNE(R) and
BARNSTEAD(R) trademarks the ORMCO(R) and "A" Company Orthodontics(R) trademarks,
each of which we believe to have widespread name brand recognition in its
respective field and all of which we intend to continue to protect. Our
subsidiaries also own various patents, including the U.S. patents for the
marking surface of Erie's SUPERFROST(R) and COLORFROST(R) slides, both of which
expire in 2001, employ various patented processes and from time to time acquire
licenses from owners of patents to apply patented processes to their operations.
Except as referred to above, we do not believe any single patent, trademark or
license is material to the operations of our business as a whole.
 
MEDICAL DEVICE REGULATION
 
     Certain of our products are medical devices which are subject to regulation
by the United States Food and Drug Administration (the "FDA") and by the
counterpart agencies of the foreign countries where our products are sold.
Pursuant to the Federal Food, Drug, and Cosmetic Act (the "FDCA"), the FDA
regulates virtually all phases of the manufacture, sale, and distribution of
medical devices, including their introduction into interstate commerce, their
manufacture, advertising, labeling, packaging, marketing, distribution and
recordkeeping. Pursuant to the FDCA and FDA regulations, certain facilities of
our operating subsidiaries are registered with the FDA as medical device
manufacturing establishments.
 
     Medical devices are classified into either Class I, II or III. Pursuant to
section 510(K) of the FDCA, the manufacturer or distributor of a Class I or II
device that is initially introduced commercially on or after May 28, 1976, must
notify the FDA of its intent to commercially introduce the device through the
submission of a premarket notification (a "510(K) Notice"). Before commercial
distribution can begin, the FDA must review the 510(K) Notice and clear the
device for commercial distribution. The FDA normally has 90 days to review the
510(K) Notice and grant or deny clearance to market on the basis that it is
substantially equivalent to a device marketed before May 28, 1976.
Alternatively, the FDA may postpone a final decision and require the submission
of additional information, which may include clinical data. If additional
information is required, review and clearance of a 510(K) Notice may be
significantly delayed. In order to clear a Class I or II device for marketing,
the FDA must determine, from the information contained in the 510(K) Notice and
any additional information that is submitted, that the device is substantially
equivalent to one or more Class I or II devices that are legally marketed in the
United States. Certain Class I devices are exempt from the 510(K) premarket
notification requirement and manufacturers of such products may proceed to
market without any submission to the FDA. If a device is not considered
"substantially equivalent", it is regulated as a Class III medical device. In
general, a Class III medical device must be expressly approved by the FDA for
commercial distribution pursuant to the submission of a premarket approval
application ("PMA"). A PMA must contain, among other information, substantial
information about the manufacture of the device and data from adequate and
well-controlled clinical trials that demonstrate that the device is both safe
and effective. The PMA approval process is substantially more complex and
lengthy than the 510(K) premarket notification process.
 
     A medical device, whether cleared for marketing under the 510(K) pathway or
pursuant to a PMA approval, is subject to ongoing regulatory oversight by the
FDA to ensure compliance with regulatory requirements, including, but not
limited to, product labeling requirements and limitations, including those
related to promotion and marketing efforts, current good manufacturing practice
and quality system requirements, record keeping, and medical device (adverse
reaction) reporting.
 
     The vast majority of our professional dental and orthodontic products are
regulated as Class I or Class II medical devices, as are most of our diagnostic,
life sciences, clinical and microbiology products. We have no Class III medical
devices.

     Dental mercury is currently regulated by the FDA as a Class I device (not
exempt from the 510(K) premarket notification requirement), and amalgam alloy is
regulated as a Class II device. In February 1993, the FDA reported to its Dental
Products Advisory Panel that it planned to regulate encapsulated mercury and
amalgam alloy, like those sold by Kerr, as a single Class II device. At the same
time, the FDA planned to propose the reclassification of dental mercury as a
Class II device, so as to conform to the Class II designation for amalgam alloy
and to the planned Class II designation for encapsulated mercury and amalgam
alloy. In October 1994, the FDA's Dental Products Panel of the Medical Devices
Advisory Committee voted unanimously to recommend reclassification of dental
mercury from Class I to Class II. Class II devices, unlike Class I devices, may
be subject to performance standards or special controls. At this time, there are
no performance standards or special controls applicable to mercury or to
encapsulated mercury and amalgam alloy, although it is possible that the FDA
could propose special controls during the reclassification process. With a Class
II designation, the amalgam products would not be subject to the PMA process.
The FDA is expected to publish its decision on the classification in 1999.
 
     All dental amalgam filling materials, including Kerr's dental amalgam
products, contain mercury. The use of mercury in various products, including
dental amalgams, is being examined by various groups and U.S. and foreign
governmental agencies as a part of an effort to reduce the amount of mercury
discharged into the environment. We are aware of at least one foreign government
agency that, as a result of a study it conducted, has proposed a plan which
would discontinue the use of amalgams once a suitable alternative is found.
 
     In addition to the environmental concerns about mercury in dental amalgams,
certain groups have expressed concerns about health effects allegedly caused by
the mercury in amalgams. These groups are active in lobbying state, federal and
foreign lawmakers and regulators to pass laws or adopt regulatory changes or
recommendations regarding alleged potential health risks of dental amalgams. To
date, these efforts have resulted in restrictions on or recommendations against
the use of amalgams in certain clinical situations by health authorities in some
countries, even though such health authorities point out there is no scientific
evidence to suggest that amalgam is causing illness in the general population.
Such actions have been taken to reduce human exposure to mercury where other
safe and practical alternatives to dental amalgam exist. In the United States,
the FDA's Dental Devices Panel, the National Institute of Health, and the United
States Public Health Service have indicated that the use of amalgams does not
cause verifiable adverse effects in patients who have amalgam fillings. All of
these agencies have recommended further research on the subject and, in large
part because of their initiatives, research with respect to potential health
effects of dental amalgams is ongoing at various places around the world.
 
ENVIRONMENTAL MATTERS
 
     Our operations entail a number of environmentally sensitive production
processes. Compliance with environmental laws and regulations along with
regulations relating to workplace safety is a significant factor in our
businesses. Our domestic facilities are subject to federal, state and local laws
and regulations concerning, among other things, solid and hazardous waste
disposal, air emissions and waste water discharge, and our foreign facilities
are subject to local laws and regulations regarding the environment. Our
operations are also subject to regulation relating to workplace safety, both in
the United States and abroad. Violations of any of these laws and regulations or
the release of toxic or hazardous materials used in our operations into the
environment could expose us to significant liability. Similarly, third party
lawsuits relating to environmental and workplace safety issues could result in
substantial liability. We believe that we are in substantial compliance with all
applicable environmental and workplace safety laws.
 
     See Item 3, "Legal Proceedings", Note 13 to our consolidated financial
statements contained in Item 8 of this Annual Report and Item 7, "Management's
Discussion and Analysis of Financial Condition and Results of Operations
- -- General" for further information regarding environmental matters.
 
RAW MATERIALS
 
     We purchase a wide range of raw materials and supplies from a number of
suppliers and do not rely on sole sources to any material extent. We do not
foresee any significant difficulty in obtaining necessary
 
                                       12
<PAGE>   16
 
materials or supplies, although such issues could arise in connection with what
is commonly referred to as the Year 2000 issue. See Item 7, "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Year
2000" for more information on the Year 2000 issue.
 
RISKS ATTENDANT TO FOREIGN OPERATIONS
 
     We conduct our businesses in numerous foreign countries and as a result are
subject to risks of fluctuations in exchange rates of various foreign currencies
and other risks associated with foreign trade. For the years 1996, 1997 and 1998
our net sales outside the United States accounted for approximately 36%, 33% and
30%, respectively, of consolidated net sales. See Item 7, "Management's
Discussion and Analysis of Financial Condition and Results of Operations
- -- General" for further information concerning the possible effects of foreign
currency fluctuations and currency hedges intended to mitigate their impact.
 
RELIANCE ON KEY DISTRIBUTORS
 
     A substantial portion of our sales of laboratory, professional dental and
orthodontic products are made through major independent distributors. On the
laboratory side these distributors historically have been Fisher, VWR, the
industrial products division of Baxter Scientific Products ("Baxter
Industrial"), Curtin Matheson Scientific, Inc. ("CMS"), and Allegiance or its
predecessor, the clinical division of Baxter Scientific Products. These major
distributors experienced significant consolidation in 1995, with Fisher
acquiring CMS and VWR acquiring Baxter Industrial. The inventory reductions
resulting from these dealer consolidations slowed sales in the domestic segment
of the laboratory business in 1995 and during the first half of 1996. The
Company felt the effects of inventory re-balancing by Fisher Scientific
(primarily impacting Barnstead Thermolyne sales) into the third quarter of 1998.
On October 9, 1998, Allegiance and Cardinal Health, Inc. announced a planned
merger, expected to be consummated during the first half of calendar 1999.
Because the businesses of Allegiance and Cardinal are complementary, we would
not expect this transaction to lead to any significant laboratory inventory
consolidation.
 
     The loss of any one of our major laboratory distributors (now Fisher, VWR
and Allegiance) could have a material adverse effect on our business. Our
subsidiaries in the laboratory segment do not have any contractual relationships
with these distributors. However, our subsidiaries have long-standing
relationships with them or their predecessors.
 
     On the dental side of our business, the dental distribution system has also
been experiencing significant consolidation, with two of our largest
distributors, Henry Schein, Inc. ("Schein") and Sullivan Dental Products, Inc.
merging in November 1997. This consolidation continued in 1998, as Schein has
continued to acquire other dental distributors, including H. Meer Dental Supply
Company. Inventory reduction from this consolidation with dealers slowed our
dental product sales through the second quarter of 1998. Although not to the
same extent as with our laboratory business, the loss of certain of our dental
distributors could have a material adverse effect on our results of operations
or financial condition.

     We consider our plants and equipment to be well-maintained and suitable for
their purposes. We have, from time to time, expanded and will continue to expand
facilities as the need arises. We expect to fund such expansions through
internally generated funds or borrowings under our Credit Facilities, as defined
in Note 7 to our consolidated financial statements contained in Item 8 of this
Annual Report. See Item 7, "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources".
 
ITEM 3. LEGAL PROCEEDINGS
 
     The Company or its subsidiaries are at any one time parties to a number of
lawsuits or subject to claims arising out of their respective operations, or the
operation of businesses divested in the 1980's for which certain subsidiaries
may continue to have legal or contractual liability, including products
liability, workplace safety and environmental claims and cases, some of which
involve claims for substantial damages. The Company and its subsidiaries are
vigorously defending lawsuits and other claims against them. Based upon the
insurance available under our insurance program and the potential for liability
with respect to claims which are uninsured, the Company believes that any
liabilities which might foreseeably result from any of the pending cases and
claims would not have a material adverse effect on the results of operations or
financial condition of the Company. There can be no assurance as to this,
however, or that litigation having such a material adverse effect will not arise
in the future.
 
     A subsidiary of the Company has been identified as a potentially
responsible party ("PRP") at the Aqua-Tech site in South Carolina (the
"Aqua-Tech Site") with respect to a previously owned facility. An action has
been conducted at the Aqua-Tech Site for the removal of surface contaminants
under the supervision of the Environmental Protection Agency ("EPA") under the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended ("CERCLA"). The Company's total contribution to such effort, which has
been paid, was approximately $46,000. The site has been placed by the EPA on the
federal National Priority List under CERCLA, which is a prerequisite to any
federally-mandated requirement for long-term remedial work at the site under
CERCLA, such as would be involved in soil and groundwater remediation. The
Company is participating with a PRP group composed of approximately 100 parties
in an agreement with the EPA to undertake a remedial investigation and
feasibility study which will be used by the EPA to determine what remedy, if
any, should be required at the site. This study is expected to be completed in
1999. Because the study, which involves extensive testing required to
characterize the existence, extent and nature of any contamination to determine
potential remedies, has not yet been completed, an estimate of the Company's
potential liability cannot be made. However, although CERCLA does provide for
joint and several liability, because the Company's share of waste allegedly sent
to the site is reportedly not more than 1% of the total waste sent, the Company
believes any ultimate liability will not have a material adverse effect on the
Company's results of operations or financial condition.
 
     On May 2, 1996, Combustion Engineering, Inc. ("CE") commenced legal
proceedings (the "CE Litigation") against the Company with respect to the former
Taylor Instruments facility in Rochester,
                                       15
<PAGE>   19
 
New York (the "Site"), an operation accounted for as a discontinued operation
when the decision was made to exit the industrial capital goods business in
1983. The CE Litigation, brought in the New York Supreme Court, Monroe County,
New York, related to claims CE made for reimbursement to it of expenses
associated with the remediation of alleged environmental contamination at the
Site. The Site was sold to CE in 1983 by the predecessor of a subsidiary of the
Company. We settled the CE Litigation on November 16, 1998. Under the settlement
agreement, the Company agreed to pay up to $10 million for remediation of
contamination located on the Site. $8.5 million was paid on the date of
settlement. Up to an additional $1.5 million will be paid if, and to the extent
that, the future cost of on-Site remediation exceeds $5.5 million. In exchange,
CE has agreed to be responsible for and to indemnify the Company with respect to
the remediation of on-Site contamination. The settlement agreement also provides
that Sybron will assume control over and be responsible for the remediation of
any potential contamination located off-Site. Our results for 1998 reflect a
pre-tax charge of $12.5 million related to the settlement. The charge includes
the Company's estimate, based in part on an analysis provided by a consultant to
the Company, of the costs associated with the remediation of off-Site
contamination. Based on current information, off-Site remediation may include a
soil vapor monitoring program and the clean-up of mercury contaminated sediments
in sewers close to the Site.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
GENERAL
 
     The following discussion should be read in conjunction with our
consolidated financial statements and the accompanying notes contained in Item 8
of this Annual Report.
 
     Our results for 1998 contain charges with respect to the restructuring of
our laboratory businesses, the restructuring of certain operations of Sybron
Dental Specialties, Inc. ("SDS") relating primarily to the consolidation of
Ormco Corporation ("Ormco") and "A" Company Orthodontics (' "A" Company'), and
merger, transaction and integration charges associated with the merger with LRS
Acquisition Corp. ("LRS")(the "LRS Merger"), the parent of "A" Company. These
charges are collectively referred to herein as the "Special Charges". In
addition, because the LRS Merger is accounted for as a pooling of interests,
beginning October 1, 1994, all data has been adjusted to reflect the historical
results of LRS as if the LRS Merger took place on the first day of the reporting
period.
 
     The Special Charges, which total $34.5 million ($23.1 million after tax),
consist of the following items:
 
(a) $9.4 million ($5.9 million after tax) relates to the realignment of our
    laboratory subsidiaries under Sybron Laboratory Products Corporation
    ("SLPC"). This restructuring charge consists primarily of severance
    expenditures associated with the consolidation of certain functions, the
    restructuring of sales and marketing activities, and costs associated with
    exiting certain product lines. Approximately $4.5 million of these charges
    are cash expenditures of which $1.6 million was paid in 1998. The majority
    of the remaining $2.9 million is expected to be paid in fiscal 1999.
 
    These actions eliminated annual costs of approximately $6.1 million.
 
(b) $14.6 million ($10.7 million after tax) relates to the consolidation of
    Ormco and "A" Company activities after the LRS Merger, and the exiting of
    certain product lines on the dental side of the business. The charge
    primarily includes severance costs, costs associated with the closure of
    Ormco's sales office in Zurich, Switzerland, and costs associated with the
    exiting of redundant product lines. Approximately $8.0 million of these
    charges are cash expenditures of which $2.9 million was paid in 1998. The
    majority of the remaining $5.1 million is expected to be paid in fiscal
    1999.
 
     These actions eliminated annual costs of approximately $11.0 million.
 
(c) $10.5 million ($6.4 million after tax) consists of transaction and merger
    and integration costs associated with the LRS Merger. We anticipate
    additional merger and integration costs of $0.7 million before taxes in each
    of the first, second and third fiscal quarters of 1999.
 
     IN ORDER TO PRESENT A COMPARISON CONSISTENT WITH PRIOR YEARS, ALL OF THE
FINANCIAL DATA IN THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS ARE PRIOR TO THE SPECIAL CHARGES AND PRIOR
TO THE RESTATEMENT OF PRIOR PERIOD DATA DUE TO THE LRS MERGER UNLESS OTHERWISE

(a) Includes the results of LRS from April 1, 1998 to September 30, 1998.
 
(b) As previously defined Special Charges relate to a restructuring charge and
    merger, transaction and integration expenses associated with the LRS Merger.
    See Note 11 to our consolidated financial statements contained in Item 8 of
    this Annual Report.
 
(c) Amounts relate to a restructuring charge. See Note 11 to our consolidated
    financial statements contained in Item 8 of this Annual Report.
 
     Both our net sales and operating income grew in 1998 from the previous
year. Net sales in 1998 increased by 17.8% over 1997. After restatement of the
prior period results for the LRS Merger, net sales increased by 14.5% over 1997.
Operating income in 1998 increased by 22.4% over 1997. After restatement of the
prior year's results for the LRS Merger and prior to the Special Charges,
operating income in 1998 increased by 20.2%, over 1997.
 
     Sales growth for the year ended September 30, 1998 was strong both
domestically and internationally. Domestic and international sales increased by
20.4% and 12.3%, respectively, over the prior year. International sales were
negatively impacted by the strengthening of the U.S. dollar and economic
weakness in the Asian region. If currency effects were removed from sales, the
international increase over 1997 would have been 16.9%. Sales to the Asian
region decreased by approximately $4.6 million when compared to the
corresponding 1997 period.
 
     Acquisitions and the LRS Merger, aided sales growth significantly in 1998,
accounting for $103.6 million and $32.4 million of the domestic and
international sales increases over the prior year. Internal sales growth was
1.0%, and showed improvement in the fourth quarter after a decline in our third
quarter. Internal growth has been negatively impacted by the strengthened U.S.
dollar, weak sales in the Asian region, distributor inventory re-balancing
impacting Barnstead Thermolyne, reduced sales at Nalge Process Technologies
Group, Inc. and a disruption in Ormco and "A" Company sales caused by the
redistribution of sales territories in connection with the LRS Merger. Kerr's
sales, which were negatively impacted by dealer inventory consolidation in the
second quarter, showed growth in the third and fourth quarters. Inventory
consolidation is, however, expected to continue to impact sales, as the dealer
network continues to consolidate. Without currency effects, internal growth was
approximately 2.3% in 1998.
 
     As discussed in Item 1, "Business -- General", we have maintained an active
program of developing and marketing both new products and product line
extensions. We believe that new product introductions are important to the
ability of our operating subsidiaries to maintain their competitive positions.
We have also pursued numerous acquisition opportunities, completing more than 60
acquisitions since 1993, 22 of which we
 
                                       22

completed in 1998, one of which was a merger and accounted for as a pooling of
interests. Acquisitions completed in 1998 were as follows:

     These acquisitions are consistent with our strategy of acquiring product
lines that can be manufactured in existing facilities, sold through existing
sales and distribution networks, or both. We intend to continue to seek out
acquisition candidates consistent with our strategy. However, there can be no
assurance of the number or size of future acquisitions.
 
     As described in Item 3, "Legal Proceedings", one of our subsidiaries is
involved as a PRP at the Aqua-Tech Site. Because the study to determine what
remedy, if any, might be required at the Aqua-Tech Site has not been completed,
an estimate of our potential liability with respect to this site cannot be made
at this time. However, although CERCLA does provide for joint and several
liability, because our share of waste allegedly sent to the site is reportedly
not more than 1% of the total waste sent, we believe that any ultimate liability
with respect to the Aqua-Tech Site will not have a material adverse effect on
our results of operations or financial condition. Also as described in Item 3,
"Legal Proceedings", another of our subsidiaries was involved in legal
proceedings relating to environmental claims brought against it by Combustion
Engineering, Inc. Our results for 1998 reflect a charge of $12.5 million ($7.75
million net of tax) for the settlement of this litigation and for the estimated
cost of certain remediation to be performed by the Company. This charge is
related to the former Taylor Instruments facility, an operation accounted for as
a discontinued operation when the decision was made to exit the industrial
capital goods business in 1983 and is reflected as a charge to discontinued
operations. See "Results of Operations -- Year Ended September 30, 1998 Compared
to the Year Ended September 30, 1997 -- Discontinued Operations", below.
 
     For additional information regarding factors that may influence our
performance, see Item 1, "Business" and Item 3, "Legal Proceedings".
 
     Our reported results of operations reflect goodwill amortization, other
amortization, and depreciation, which are non-cash charges, totaling $45.7
million, $50.7 million and $57.1 million in 1996, 1997 and 1998, respectively.
Depreciation and amortization increased in 1998 due to our acquisition activity
and associated amortization of stepped up assets and goodwill. In 1998,
depreciation and amortization associated with the leveraged buyout in 1987 of a
company known at the time as Sybron Corporation (the "Acquisition")
 
                                       24
<PAGE>   28
 
decreased by approximately $4.7 million, primarily as a result of the completed
write-off of tangible and intangible assets with a ten year life. This decrease
was entirely offset by the impact of past and continuing acquisition activity.
As discussed below in "Liquidity and Capital Resources", our earnings before
interest, taxes, depreciation and amortization ("EBITDA") amounted to $193.3
million, $237.0 million and $281.9 million in 1996, 1997 and 1998, respectively.
EBITDA while not a generally accepted accounting principles measure, represents,
for any relevant period, net income (except that extraordinary items and
discontinued operations are excluded) plus (i) interest expense, (ii) provision
for income taxes, (iii) Special Charges, (iv) depreciation, and (v)
amortization, all determined on a consolidated basis and in accordance with
generally accepted accounting principles.
 
     Substantial portions of our sales, income and cash flows are derived
internationally. The financial position and the results of operations from
substantially all of our international operations, other than most U.S. export
sales, are measured using the local currency of the countries in which such
operations are conducted and are then translated into U.S. dollars. While the
reported income of foreign subsidiaries will be impacted by a weakening or
strengthening of the U.S. dollar in relation to a particular local currency, the
effects of foreign currency fluctuations are partially mitigated by the fact
that manufacturing costs and other expenses of foreign subsidiaries are
generally incurred in the same currencies in which sales are generated. Such
effects of foreign currency fluctuations are also mitigated by the fact that
such subsidiaries' operations are conducted in numerous foreign countries and,
therefore, in numerous foreign currencies. In addition, our U.S. export sales
may be impacted by foreign currency fluctuations relative to the value of the
U.S. dollar as foreign customers may adjust their level of purchases upward or
downward according to the weakness or strength of their respective currencies
versus the U.S. dollar.
 
     From time to time we may employ currency hedges to mitigate the impact of
foreign currency fluctuations. If currency hedges are not employed, we may be
exposed to earnings volatility as a result of foreign currency fluctuations. In
October 1997, we decided to employ a series of foreign currency options with a
U.S. dollar notional amount of approximately $13.6 million at a cost of
approximately $0.4 million. Two of these options were sold in the third quarter
of 1998 for $0.4 million. The remaining options expired worthless in the fourth
quarter of 1998. These options were designed to protect the Company from
potential detrimental effects of currency movements associated with the U.S.
dollar versus the German mark and the French franc as compared to the third and
fourth quarters of 1997. In October 1998, we again decided to employ a series of
foreign currency options with a U.S. dollar notional amount of approximately
$45.7 million at a cost of approximately $0.3 million. These options are
designed to protect the Company from potential detrimental effects of currency
movements associated with the U.S. dollar versus the German mark, French franc,
Swiss franc, and Japanese yen in the second, third and fourth quarters of fiscal
1999 as compared to the second, third and fourth quarters of 1998.
 
     The following table sets forth our domestic sales and sales outside the
United States in 1996, 1997 and 1998 and includes net sales from the Merger. See
also Note 15 to our consolidated financial statements contained in Item 8 of
this Annual Report.

RESULTS OF OPERATIONS
 
  YEAR ENDED SEPTEMBER 30, 1998
  COMPARED TO THE YEAR ENDED SEPTEMBER 30, 1997
 
     Net Sales. Net sales for the year ended September 30, 1998 were $936.7
million, an increase of 17.8% from 1997 net sales of $795.1 million. After
restating for the LRS Merger, net sales for the year ended
 
                                       25
<PAGE>   29
 
September 30, 1998 were $960.7 million, an increase of 14.5% from 1997 net sales
of $839.0 million. Net sales in the laboratory segment were $605.6 million in
1998, an increase of 23.3% from 1997 net sales of $491.2 million. Increased net
sales in the laboratory segment resulted primarily from: (i) net sales of
products of acquired companies (approximately $107.9 million), (ii) increased
sales of new products (approximately $5.4 million), (iii) price increases
(approximately $4.9 million) and (iv) increased sales of existing products
(approximately $0.2 million). Increased sales were partially offset by
unfavorable foreign currency fluctuations (approximately $4.4 million). In the
dental segment, net sales were $331.1 million in 1998, an increase of 9.0% from
1997 net sales of $303.9 million. Increased net sales in the dental segment
resulted primarily from: (i) net sales of products of acquired companies
(approximately $28.1 million) and (ii) increased net sales of new products
(approximately $6.5 million). Increased sales were partially offset by: (i)
unfavorable foreign currency fluctuations (approximately $7.2 million) and (ii)
reduced net sales of existing products (approximately $0.1 million).
 
     Gross Profit. Gross profit for the year ended September 30, 1998 was $482.6
million, an increase of 19.7% from 1997 gross profit of $403.2 million. After
restating for the LRS Merger and before the Special Charges discussed below,
gross profit for the year ended September 30, 1998 was $496.9 million, an
increase of 15.7% from 1997 gross profit of $429.4 million. Gross profit in the
laboratory segment was $288.1 million (47.6% of segment net sales), an increase
of 24.6% from 1997 gross profit of $231.2 million (47.1% of segment net sales).
Increased gross profit in the laboratory segment was primarily from: (i) the
effects of acquired companies (approximately $53.1 million), (ii) increased
volume (approximately $7.8 million), (iii) price increases (approximately $4.9
million) and (iv) reduced amortization (approximately $1.5 million). Increased
gross profit was partially offset by: (i) an unfavorable product mix
(approximately $4.0 million), (ii) increased manufacturing overhead
(approximately $3.8 million) and (iii) unfavorable foreign currency fluctuations
(approximately $2.5 million). In the dental segment, gross profit was $194.5
million (58.7% of segment net sales), an increase of 13.1% from 1997 gross
profit of $172.0 million (56.6% of segment net sales). Increased gross profit in
the dental segment was primarily from : (i) the effects of acquired companies
(approximately $19.3 million), (ii) an improved product mix (approximately $3.0
million), (iii) increased volume (approximately $2.1 million), (iv) decreased
manufacturing overhead (approximately $2.0 million), (v) inventory valuation
adjustments (approximately $1.8 million) and (vi) reduced amortization
(approximately $1.2 million), partially offset by unfavorable foreign currency
impacts (approximately $6.9 million).
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses for 1998, including amortization of purchase accounting
adjustments and goodwill associated with acquisitions, were $262.3 million
(28.0% of net sales), as compared to $223.2 million (28.1% of net sales) for
1997. After restating for the LRS Merger, selling, general and administrative
expenses for 1998, including amortization of purchase accounting adjustments and
goodwill associated with acquisitions, were $272.1 million (28.3% of net sales),
as compared to $242.3 million (28.9% of net sales) for 1997. General and
administrative expenses at the corporate level, including amortization of
purchase accounting adjustments, were $17.2 million in 1998, representing a
decrease of 6.8% from $18.5 million in 1997. The decrease at the corporate level
was primarily due to reduced depreciation and amortization expense of certain
tangible and intangible assets that became fully amortized or depreciated in the
prior fiscal year. Selling, general and administrative expenses at the
subsidiary level, including amortization of intangibles, were $245.0 million,
representing a $40.3 million (19.7%) increase over $204.7 million in 1997. After
restating for the LRS Merger, selling, general and administrative expenses at
the subsidiary level, including amortization of intangibles, were $254.9
million, representing a $31.1 million (13.9%) increase over $223.8 million in
1997. Increases at the subsidiary level were primarily from: (i) increased
selling, general and administrative expenses as a result of acquired businesses
(approximately $27.5 million), (ii) increased general and administrative
expenses (approximately $6.6 million), (iii) increased amortization of
intangibles primarily as a result of acquisitions (approximately $6.0 million)
and (iv) increased marketing expenses (approximately $4.7 million), partially
offset by: (i) favorable foreign currency fluctuations (approximately $4.1
million) and (ii) reduced research and development expenses (approximately $0.4
million).

     Special Charges.  The results of 1998 include the Special Charges which
total $34.5 million ($23.1 million after tax) as follows:
 
(a) In June 1998, the Company recorded a restructuring charge of $24.0 million
    ($16.7 million after tax or $.16 per share on a diluted basis) for the
    rationalization of certain acquired companies, combination of certain
    production facilities, movement of certain customer service and marketing
    functions, and the exiting of several product lines. The restructuring
    charge has been classified as components of cost of sales ($6.4 million),
    selling, general and administrative expenses ($16.9 million) and income tax
    expense ($0.7 million). Principal items included in the reserve were
    severance and termination costs for approximately 165 notified employees
    (primarily production, sales and marketing personnel) (approximately $8.4
    million), the non-cash write-off of certain fixed assets and inventory
    associated with exited product lines (approximately $8.7 million), the
    non-cash write-off of goodwill associated with discontinued product lines
    (approximately $2.1 million), remaining lease payments and shut down costs
    on exited facilities and other contractual obligations (approximately $2.0
    million), a statutory tax penalty (approximately $0.7 million), and other
    related restructuring costs (approximately $2.1 million). As of September
    30, 1998, the Company has made cash payments of approximately $4.6 million
    and has written off approximately $11.4 million of fixed assets, inventory,
    goodwill and other miscellaneous items relating to the restructuring
    reserve. The remaining amount of approximately $8.0 million relates to
    obligations expected to be paid in the next twelve months.
 
(b) The Company incurred approximately $10.5 million ($6.4 million after tax or
    $.06 per share on a diluted basis) of costs associated with the merger,
    transition and integration of the "A" Company. The majority of these
    expenses were adjustments to the LRS Merger consideration. The Company
    expects to incur an additional $0.7 million before taxes in each of the
    first, second and third quarters of fiscal 1999 in connection with further
    integration costs.
 
     Operating Income.  As a result of the foregoing, operating income was
$220.3 million (23.5% of net sales) for 1998, as compared with $180.0 million
(22.6% of net sales) in 1997. After restating for the LRS Merger and before the
Special Charges, operating income was $224.9 million (23.4% of net sales) for
1998, as compared with $187.1 million (22.3% of net sales) in 1997. Operating
income in the laboratory segment was $140.6 million (23.2% of segment net sales)
as compared to $110.9 million (22.6% of segment net sales) in 1997. Operating
income in the dental segment was $79.7 million (24.1% of segment net sales) in
1998 as compared to $69.0 million (22.7% of segment net sales) in 1997.
 
     Interest Expense.  Interest expense, after restating for the LRS Merger,
was $56.9 million in 1998, an increase of $9.7 million from 1997. The increase
resulted from a higher average debt balance in 1998, resulting primarily from
our acquisition activity.
 
     Income Taxes.  Taxes on income from continuing operations, after restating
for the LRS Merger, were $56.0 million, an increase of $0.8 million from 1997.
The increase resulted primarily from increased taxable earnings partially offset
by increased expenses associated with the Special Charges.
 
     Discontinued Operations.  On May 2, 1996, Combustion Engineering, Inc.
("CE") commenced legal proceedings (the "CE Litigation") against the Company
with respect to the former Taylor Instruments facility in Rochester, New York
(the "Site"), an operation accounted for as a discontinued operation when the
decision was made to exit the industrial capital goods business in 1983. The CE
Litigation, brought in the New York Supreme Court, Monroe County, New York,
related to claims CE made for reimbursement to it of expenses associated with
the remediation of alleged environmental contamination at the Site. The Site was
sold to CE in 1983 by the predecessor of a subsidiary of the Company. We settled
the CE Litigation on November 16, 1998. Under the settlement agreement, the
Company agreed to pay up to $10 million for remediation of contamination located
on the Site. $8.5 million was paid on the date of settlement. Up to an
additional $1.5 million will be paid if, and to the extent that, the future cost
of on-Site remediation exceeds $5.5 million. In exchange, CE has agreed to be
responsible for and to indemnify the Company with respect to the remediation of
on-Site contamination. The settlement agreement also provides that Sybron will
assume control over and be responsible for the remediation of any potential
contamination located off-Site. Our results for 1998 reflect a pre-tax charge of
$12.5 million related to the settlement. The charge includes the Company's
                                       27
<PAGE>   31
 
estimate, based in part on an analysis provided by a consultant to the Company,
of the costs associated with the remediation of off-Site contamination. Based on
current information, off-Site remediation may include a soil vapor monitoring
program and the clean-up of mercury contaminated sediments in sewers close to
the Site. See Item 3, "Legal Proceedings" and Note 13 to our consolidated
financial statements contained in this Annual Report
 
     Net Income.  As a result of the foregoing, we had net income after the LRS
Merger and Special Charges of $70.3 million in 1998, as compared to net income
of $83.1 million in 1997.
 
     Depreciation and Amortization.  Depreciation and amortization expense is
allocated among cost of sales, selling, general and administrative expenses and
other expense. Depreciation and amortization increased in 1998 due to additional
depreciation and amortization from the step-up of assets and goodwill recorded
from the various acquisitions as well as routine operating capital expenditures.
 
     New Accounting Pronouncements.  In February 1997, the Financial Accounting
Standards Board ("FASB") issued Statement of Financial Accounting Standards No.
128, "Earnings Per Share". This change has required us to report both basic and
diluted earnings per share ("EPS") beginning in 1998 and resulted in basic EPS
increasing over previously reported primary and fully diluted EPS by $.01 and
$.03 in 1996 and 1997, respectively, before restatement for the LRS Merger.
Diluted EPS remained the same as previously reported primary and fully diluted
EPS in 1996 and 1997.
 
     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income" ("SFAS 130"), which is effective for
financial statements for periods beginning after December 15, 1997. As a result
of SFAS 130, we will be required to separately report comprehensive income
components previously excluded from our net income. Comprehensive income
includes all changes to equity during a period except those resulting from
investments by or distributions to shareholders. Because comprehensive income is
subject to external factors beyond our control, including but not limited to
foreign currency fluctuations and economic factors, we cannot at this time
estimate impacts of SFAS 130. It is our intention to adopt SFAS 130 in the first
quarter of fiscal 1999.
 
     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"), which is effective for financial statements for periods beginning
after December 15, 1997. SFAS 131 establishes standards for the way we are to
report information about operating segments in annual financial reports issued
to shareholders. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. It is our intention
to adopt SFAS 131 in fiscal 1999 and anticipate disclosing additional segments.
 
     In February 1998, the FASB issued Statement of Financial Accounting
Standards No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits,"("SFAS 132") which revises disclosures about pensions
and other postretirement benefit plans. SFAS 132 will be effective for our 1999
fiscal year financial statements and restatement of disclosures for earlier
years will be required unless the information is not readily available. We are
currently evaluating the extent to which our financial statements will be
affected by SFAS 132.
 
     In March 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-1 ("SOP 98-1"), "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use", which specifies the
accounting treatment provided for computer software costs depending upon the
type of cost incurred. This statement is effective for our fiscal year 2000
financial statements and restatement of prior years will not be permitted. We
are currently evaluating the extent to which SOP 98-1 will effect our financial
position and results of operations.
 
     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"), which is effective for financial statements for periods beginning after
December 15, 1999. SFAS 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts and hedging activities. It is our intention to adopt SFAS 133 in
our first quarter of our 2001 fiscal year. We do not believe the adoption of
SFAS 133 will have a material impact on the financial statements.

RESULTS OF OPERATIONS
 
  YEAR ENDED SEPTEMBER 30, 1997
  COMPARED TO THE YEAR ENDED SEPTEMBER 30, 1996
 
     Net Sales.  Net sales for the year ended September 30, 1997 were $795.1
million, an increase of 17.9% from 1996 net sales of $674.5 million. After
restating for the LRS Merger, net sales for the year ended September 30, 1997
were $839.0 million, an increase of 17.3% from 1996 net sales of $715.4 million.
Net sales in the laboratory segment were $491.2 million in 1997, an increase of
24.6% from 1996 net sales of $394.3 million. Increased net sales in the
laboratory segment resulted primarily from: (i) net sales of products of
acquired companies (approximately $89.3 million), (ii) price increases
(approximately $7.0 million), (iii) net sales of new products (approximately
$5.2 million) and (iv) increased net sales of existing products (approximately
$1.8 million), partially offset by unfavorable foreign currency fluctuations
(approximately $6.0 million). In the dental segment, net sales were $303.9
million in 1997, an increase of 8.5% from 1996 net sales of $280.1 million.
Increased net sales in the dental segment resulted primarily from: (i) increased
net sales of existing products (approximately $16.3 million), (ii) net sales of
products of acquired companies (approximately $9.9 million) and (iii) net sales
of new products (approximately $6.4 million), partially offset by unfavorable
foreign currency fluctuations (approximately $8.9 million).
 
     Gross Profit.  Gross profit for the year ended September 30, 1997 was
$403.2 million, an increase of 19.0% from 1996 gross profit (before the
restructuring charge discussed below) of $338.9 million. After restating for the
LRS Merger and before the restructuring charges discussed below, gross profit
for the year ended September 30, 1997 was $429.4 million, an increase of 18.7%
from 1996 gross profit of $361.6 million. Gross profit in the laboratory segment
was $231.2 million (47.1% of segment net sales), an increase of 28.1% from 1996
gross profit of $180.5 million (45.8% of segment net sales). Increased gross
profit in the laboratory segment was primarily from: (i) the effects of acquired
companies (approximately $43.0 million) and (ii) increased volume (approximately
$15.0 million), partially offset by (i) increased material costs (approximately
$2.5 million), (ii) unfavorable foreign currency fluctuations (approximately
$2.3 million), (iii) higher fixed overhead (approximately $1.1 million) and (iv)
increased scrap (approximately $0.9 million). In the dental segment, gross
profit was $172.0 million (56.6% of segment net sales), an increase of 8.6% from
1996 gross profit of $158.3 million (56.5% of segment net sales). Increased
gross profit in the dental segment was primarily from: (i) increased volume
(approximately $13.1 million) and (ii) the effects of acquired companies
(approximately $4.7 million), partially offset by unfavorable foreign currency
impacts (approximately $4.3 million).
 
     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses for 1997 were $223.2 million (28.1% of net sales) as
compared to $194.6 million (before the restructuring charges discussed below)
(28.9% of net sales) in 1996. After restating for the LRS Merger, selling,
general and administrative expenses for 1997, including amortization of purchase
accounting adjustments and goodwill associated with acquisitions, were $242.3
million (28.9% of net sales), as compared to $213.5 million (before the
restructuring charges discussed below) (29.8% of net sales) for 1996. General
and administrative expenses at the corporate level, including amortization of
goodwill, were $18.5 million in 1997, representing a decrease of 14.9% from
$21.7 million in 1996. Decreases at the corporate level were primarily from: (i)
reduced legal expense (approximately $1.9 million), (ii) reduced depreciation
and amortization expense (approximately $1.0 million) and (iii) a reduction in
employee benefits expense (approximately $0.3 million). Selling, general and
administrative expenses at the subsidiary level, including amortization of
intangibles, were $204.7 million, representing a $31.8 million (18.4%) increase
over $172.9 million in 1996. Increases at the subsidiary level were primarily
due to: (i) increased selling, general and administrative expenses as a result
of acquired businesses (approximately $18.0 million), (ii) increased marketing
expenses (approximately $5.1 million), (iii) increased general and
administrative expenses (approximately $4.0 million), (iv) increased
amortization of intangibles primarily as a result of acquisitions (approximately
$2.9 million), (v) unfavorable foreign currency impacts (approximately $1.8
million) and (vi) increased research and development expenses (approximately
$0.7 million).

     Restructuring Charge.  In March of 1996, we recorded a restructuring charge
of $8.3 million ($6.1 million after-tax or $0.06 per share) for the
rationalization of certain acquired companies, combination of certain production
facilities, movement of certain customer service and marketing functions and the
exiting of several product lines. Approximately $4.5 million and $3.2 million
were charged against this reserve in 1996 and 1997, respectively. As of
September 30, 1997 approximately $0.6 million of the established liability
remained to be expended. In 1998, substantially all of the remaining $0.6 was
expended. Principal items in the charge were severance and termination costs for
approximately 130 notified employees (primarily production, sales and marketing
personnel) (approximately $2.3 million), remaining lease payments and shutdown
costs on exited facilities (approximately $2.1 million), the non-cash write-off
of certain fixed assets and inventory associated with exited product lines,
primarily of SDS (approximately $2.5 million), a statutory tax penalty
(approximately $0.7 million) and other related restructuring costs
(approximately $0.7 million).
 
     Operating Income.  As a result of the foregoing, operating income was
$180.0 million (22.6% of net sales) for 1997, as compared with $136.7 million
(including the restructuring charge mentioned above) (20.3% of net sales) in
1996. After restating for the LRS Merger, operating income was $187.1 million
(22.3% of net sales) for 1997, as compared with $140.6 million (19.7% of net
sales) in 1996. Operating income in the laboratory segment was $110.9 million
(22.6% of segment net sales) as compared to $82.6 million (20.9% of segment net
sales) in 1996. Operating income in the dental segment was $69.1 million (22.7%
of segment net sales) in 1997 as compared to $54.1 million (19.3% of segment net
sales) in 1996. Both the laboratory and dental segment margins were unfavorably
impacted in 1996 by the nonrecurring restructuring charge referred to above.
 
     Interest Expense.  Interest expense was $47.2 million in 1997, an increase
of $7.7 million from 1996. The increase resulted from a higher average debt
balance in 1997, resulting primarily from our acquisition activity.
 
     Income Taxes.  Taxes on income were $55.2 million, an increase of $12.2
million. The increase was primarily the result of increased taxable earnings.
 
     Extraordinary Item.  As a result of the Second Amendment to the Credit
Facilities (as defined later herein), we wrote off, as an extraordinary item,
approximately $1.0 million (approximately $0.7 million net of income tax) of
unamortized deferred financing fees.
 
     Net Income.  As a result of the foregoing, we had net income of $83.1
million in 1997, as compared to net income of $57.5 million in 1996.
 
     Depreciation and Amortization.  Depreciation and amortization expense is
allocated among cost of sales, selling, general and administrative expenses and
other expense. Depreciation and amortization increased in 1997 due to additional
depreciation and amortization from the step-up of assets and goodwill recorded
from the various acquisitions as well as routine operating capital expenditures.
 
INFLATION
 
     We do not believe that inflation has had a material impact on net sales or
income during any of the periods presented above. There can be no assurance,
however, that our business will not be affected by inflation in the future.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     As a result of the Acquisition and the acquisitions we completed since
1987, we have increased the carrying value of certain tangible and intangible
assets consistent with generally accepted accounting principles. Accordingly,
our results of operations include a significant level of non-cash expenses
related to the depreciation of fixed assets and the amortization of intangible
assets, including goodwill. After restatement for the LRS Merger, goodwill and
intangible assets increased by approximately $215.1 million in 1998, primarily
as a result of continued acquisition activity. We believe, therefore, that
EBITDA represents the more appropriate measure of our ability to internally fund
our capital requirements.
 
                                       30
<PAGE>   34
 
     Our capital requirements arise principally from indebtedness incurred in
connection with the permanent financing for the Acquisition and our subsequent
refinancings, our working capital needs, primarily related to inventory and
accounts receivable, our capital expenditures, primarily related to purchases of
machinery and molds, the purchase of various businesses and product lines in
execution of our acquisition strategy, payments to be made in connection with
our restructuring, and the periodic expansion of physical facilities. It is
currently our intent to pursue our acquisition strategy. If acquisitions
continue at our historical pace, of which there can be no assurance, we may
require financing beyond the capacity of our Credit Facilities (as defined
below). In addition, certain acquisitions previously completed contain "earnout
provisions" requiring further payments in the future if certain financial
results are achieved by the acquired companies. See Note 14 to our consolidated
financial statements contained in Item 8 of this Annual Report. With respect to
the restructuring charge of approximately $24.0 million, of which approximately
$12.6 million represents cash expenditures, as of September 30, 1998, we have
made cash payments of approximately $4.6 million. Approximately $8.0 million
remains to be paid over the next twelve months.
 
     The statement contained in the immediately preceding paragraph concerning
our intent to continue to pursue our acquisition strategy is a forward-looking
statement. Our ability to continue our acquisition strategy is subject to a
number of uncertainties, including, but not limited to, our ability to raise
capital beyond the capacity of our Credit Facilities and the availability of
suitable acquisition candidates at reasonable prices. See "Cautionary Factors"
below.
 
     On July 31, 1995, we entered into a credit agreement (as amended, the
"Credit Agreement") with Chemical Bank (now known as The Chase Manhattan Bank
("Chase")) and certain other lenders providing for a term loan facility of $300
million (the "Term Loan Facility"), and a revolving credit facility of $250
million (the "Revolving Credit Facility") (collectively the "Credit
Facilities"). On the same day, we borrowed $300 million under the Term Loan
Facility and approximately $122.5 million under the Revolving Credit Facility.
Approximately $158.5 million of the borrowed funds were used to finance the
acquisition of the Nunc group of companies (approximately $9.1 million of the
acquisition price for Nunc was borrowed under our previous credit facilities).
The remaining borrowed funds of approximately $264.0 million were used to repay
outstanding amounts, including accrued interest, under our previous credit
facilities and to pay certain fees in connection with such refinancing. On July
9, 1996, under the First Amendment to the Credit Agreement (the "First
Amendment"), the capacity of the Revolving Credit Facility was increased to $300
million, and a competitive bid process was established as an additional option
for us in setting interest rates. On April 25, 1997, we entered into the Second
Amended and Restated Credit Agreement (the "Second Amendment"). The Second
Amendment was an expansion of the Credit Facilities. The Term Loan Facility was
restored to $300 million by increasing it by $52.5 million (equal to the amount
previously repaid through April 24, 1997) and the Revolving Credit Facility was
expanded from $300 million to $600 million. On April 25, 1997, we borrowed a
total of $622.9 million under the Credit Facilities. The proceeds were used to
repay $466.3 million of previously existing LIBOR and ABR loans (as defined
below) (including accrued interest and certain fees and expenses) under the
Credit Facilities and to pay $156.6 million with respect to the purchase of
Remel Limited Partnership which includes both the purchase price and payment of
assumed debt. The $72 million of CAF borrowings (as defined below) remained in
place. On July 1, 1998, we completed the First Amendment to the Second Amended
Credit Agreement (the "Additional Amendment"). The Additional Amendment provided
for an increase in the Term Loan Facility of $100 million. On July 1, 1998, we
used the $100 million of proceeds from the Additional Amendment to pay $100
million of existing debt balances under the Revolving Credit Facility. The
Additional Amendment also provides us with the ability to use proceeds from the
issuance of additional unsecured indebtedness of up to $300 million to pay
amounts outstanding under the Revolving Credit Facility without reducing our
ability to borrow under the Revolving Credit Facility in the future.
 
     Payment of principal and interest with respect to the Credit Facilities and
the Sale/Leaseback (as defined later herein) is anticipated to be our largest
use of operating funds in the future. The Credit Facilities provide for an
annual interest rate, at our option, equal to (a) the higher of (i) the rate
from time to time publicly announced by Chase in New York City as its prime
rate, (ii) the federal funds rate plus 1/2 of 1%, and (iii) the base CD rate
plus 1%, (collectively referred to as "ABR") or (b) the London interbank offered
 
                                       31
<PAGE>   35
 
rate ("LIBOR") plus 1/2% to 7/8% (the "LIBOR Margin") depending upon the ratio
of our total debt to Consolidated Adjusted Operating Profit (as defined), or (c)
with respect to the Revolving Credit Facility, the rate set by the competitive
bid process among the parties to the Revolving Credit Facility established in
the First Amendment ("CAF"). The average interest rate on the Term Loan Facility
(inclusive of the swap agreements described below) in 1998 was 6.7% and the
average interest rate on the Revolving Credit Facility in 1998 was 6.6%.
 
     As a result of the terms of the Credit Agreement, we are sensitive to a
rise in interest rates. In order to reduce our sensitivity to interest rate
increases, from time to time we enter into interest rate swap agreements. At
September 30, 1998, swap agreements aggregating a notional amount of $325
million were in place to hedge against a rise in interest rates. The net
interest rate paid by us is approximately equal to the sum of the swap agreement
rate plus the applicable LIBOR Margin. During all of 1998, the LIBOR Margin was
 .75%. The swap agreement rates and durations are as follows:

July 31, 2002........................    $75 million       May 7, 1997                  6.385%
</TABLE>
 
     On October 23, 1998 we entered into an additional swap agreement in the
notional amount of $50 million. The agreement expires on July 31, 2002 and has a
swap agreement rate of 4.733%.
 
     Also as part of the permanent financing for the Acquisition, on December
22, 1988, we entered into the sale and leaseback of what were our principal
domestic facilities at that time (the "Sale/Leaseback"). In January 1994, the
annual obligation under the Sale/Leaseback increased from $2.9 million to $3.3
million, payable monthly. On the fifth anniversary of the leases and every five
years thereafter (including renewal terms), the rent will be increased by the
percentage equal to 75% of the percentage increase in the Consumer Price Index
over the preceding five years. The percentage increase to the rent in any
five-year period is capped at 15%. The next adjustment will occur on January 1,
1999.
 
     We intend to fund our acquisitions, working capital requirements, capital
expenditure requirements, principal and interest payments, obligations under the
Sale/Leaseback, restructuring expenditures, other liabilities and periodic
expansion of facilities, to the extent available, with funds provided by
operations and short-term borrowings under the Revolving Credit Facility. To the
extent that funds are not available from those sources, particularly with
respect to our acquisition strategy, we intend to raise additional capital.
 
     As set forth above, after the Second Amendment, the Revolving Credit
Facility provides up to $600 million in available credit. At September 30, 1998,
there was approximately $149.9 million of available credit under the Revolving
Credit Facility. Under the Term Loan Facility, on July 31, 1997 we began to
repay principal in 21 consecutive quarterly installments by paying the $8.75
million due in 1997, and the $35.0 million due in 1998. Annual payments for
fiscal years 1999-2002 are due as follows: $36.25 million, $42.5 million, $53.75
million and $223.75 million.
 
     The Credit Agreement contains numerous financial and operating covenants,
including, among other things, restrictions on investments; requirements that we
maintain certain financial ratios; restrictions on our ability to incur
indebtedness or to create or permit liens or to pay cash dividends in excess of
$50.0 million plus 50% of our consolidated net income for each fiscal quarter
ending after June 30, 1995, less any dividends paid after June 22, 1994; and
limitations on incurrence of additional indebtedness. The Credit Agreement
permits us to make acquisitions provided we continue to satisfy all financial
covenants upon any such acquisition. Our ability to meet our debt service
requirements and to comply with such covenants is dependent upon our future
performance, which is subject to financial, economic, competitive and other
factors affecting us, many of which are beyond our control.

YEAR 2000
 
     Historically, certain computer programs were written using two digits
rather than four to identify the applicable year. Accordingly, software used by
the Company and others with whom it does business may be unable to interpret
dates in the calendar year 2000. This situation, commonly referred to as the
Year 2000 ("Y2K") issue, could result in computer failures or miscalculations,
causing disruption of normal business activities. The Y2K issue could arise at
any point in our supply, manufacturing, distribution, administration,
information, accounting and financial systems. Incomplete or untimely resolution
of the Y2K issue by the Company, key suppliers, customers and other parties,
could have a material adverse effect on the Company's results of operations,
financial condition and cash flow.
 
     We are addressing the Y2K issue with a corporate-wide initiative sponsored
by Sybron's Vice President-Finance and Chief Financial Officer and its Vice
President-General Counsel and Secretary, and led at the subsidiary level by the
Executive Vice President and Chief Financial officer at SLPC and the Vice
President and Chief Information Officer at SDS. The four main phases of the
initiative include (1) identification of affected mission critical software
utilized by both information and non-information technology systems, (2)
assessment of the risk associated with such affected software and development of
a plan for modifying or replacing the software, (3) implementation of solutions
under the plan, and (4) testing of the solutions. The initiative also includes
communication with our significant suppliers, vendors and customers to determine
the extent to which we are vulnerable to any failures by them to address the Y2K
issue. The program contemplates the development of contingency plans where
needed to deal with Company systems and third party issues.
 
     We have completed more than 75% of the identification, risk-assessment and
plan development phases of our initiative with respect to our internal systems.
We recognize that because of the nature of the Year 2000 problem, work in these
areas will continue until the Year 2000. Our work in these phases has included
both information technology ("IT") and non-information technology, ("non-IT")
systems. The IT systems include accounting, financial, budgeting, invoicing and
other business systems. Non-IT systems include manufacturing production lines
and equipment, elevators, heating, ventilation and air conditioning systems, and
telephone systems.
 
     We are approximately 40-50% along in our implementation phase. In most
cases, we are upgrading existing software to versions which are Y2K compliant.
In other cases entire software platforms are being replaced with more current,
compliant systems, internally developed software is being reprogrammed, and
hardware is being replaced.
 
     The testing phase has begun and will be ongoing as systems are remediated
or replaced. We have completed approximately 50% of the testing required for
systems that have been remediated or replaced to date. Our efforts in this phase
include testing by end users and determination by appropriate local Y2K project
managers that the remediated or replaced systems are Y2K compliant. In those
cases where testing cannot be conducted by Company personnel, as in the case of
certain imbedded logic components, we rely on vendor certifications.
 
     The Company and each of its subsidiaries have project schedules which
include the task of corresponding with critical vendors, customers, suppliers
and other third parties to inquire about their Y2K readiness. The Company, and
most of its subsidiaries, have begun this process. Although responses to date
indicate that some third parties probably will not be Y2K compliant, no material
issues in this regard have been identified. However, it is too early in this
process to assess the third party risk.
 
     Our Year 2000 initiative contemplates the development of contingency plans
as we test our software solutions and complete our risk assessments with respect
to third parties. Our contingency planning is therefore in the early stages of
development and we have not completed a comprehensive analysis of the
operational problems and costs (including loss of revenue) that would be
reasonably likely to result from the failure by the Company or critical third
parties to achieve Y2K compliance on a timely basis. A contingency plan has not
yet been developed for dealing with our most reasonably likely worst case
scenarios, and such scenarios have not yet been clearly identified. However,
based on the information we have to date we believe
 
                                       33
<PAGE>   37
 
the most reasonably likely worst case scenarios for our businesses would be the
failure of an important supplier to be able to deliver required materials, parts
or products, or the failure of a significant distributor to be able to get the
Company's products to customers. We contemplate the development of contingency
plans to deal with these potential problems as they are identified. For example,
if it appears that a critical vendor will not be Y2K compliant, we may establish
alternative sourcing, build inventory, or identify a substitute product or
material. If a critical distributor appears it will not be Y2K compliant, we
will have to develop plans for alternate distribution.
 
     Our goal is to substantially complete all phases of our initiative by March
31, 1999 with respect to our core businesses, including the development of plans
for contingencies identified by then. We expect the need to implement any
contingency plan will occur, if at all, after March 1999. We also expect to have
to continue to develop contingency plans for Y2K issues arising after that time.
For example, our March 1999 goal for core businesses does not encompass recently
acquired businesses or businesses we acquire in the future pursuant to our
acquisition program. Separate and appropriate goals will be set for acquired
businesses as acquisitions are completed.
 
     The historical and estimated future costs to the Company of Y2K compliance
are contained in the following table. The primary components of the reported
costs are external consulting and hardware and software upgrades. We do not
separately track internal costs of the Y2K initiative. Internal costs are
principally payroll costs of employees involved in the initiative. Also, the
reported costs do not include costs related to manufacturing equipment for SDS
because, although SDS has identified the equipment that may require remediation,
the cost of such remediation has not yet been determined. Our Year 2000
remediation efforts are funded from the Company's cash flow and from borrowings
under the Revolving Credit Facility. The Company has not deferred any
significant information technology projects due to its Year 2000 efforts.

     The foregoing statements about our goals for substantial completion of our
Y2K initiative with respect to our core businesses, and the foregoing estimates
of our Y2K costs are forward looking statements. These statements and estimates
are based upon management's best estimates, which were derived using numerous
assumptions regarding future events, including the continued availability of
certain resources, third-party remediation plans, and other factors. There can
be no assurance that these estimates will prove to be accurate, and actual
results could differ materially from those currently anticipated. Specific
factors that could cause such material differences include, but are not limited
to, the availability and cost of personnel trained in Y2K issues, the ability to
identify, assess, remediate and test all relevant computer codes and embedded
technology, the indirect impact of third parties with whom we do business and
who do not mitigate their Y2K compliance problems, and similar uncertainties.
 
EUROPEAN ECONOMIC MONETARY UNIT
 
     On January 1, 1999, eleven of the European Union countries (including four
countries in which we have operations) are scheduled to adopt the Euro as their
single currency. At that time, a fixed exchange rate will be established between
the Euro and the individual countries' existing currencies (the "legacy
currencies"). The Euro will trade on currency exchanges and be available for
non-cash transactions. Following the introduction of the Euro, the legacy
currencies will remain legal tender in the participating countries during a
transition period from January 1, 1999 through January 1, 2002. Beginning on
January 1, 2002, the European Central Bank will issue Euro-denominated bills and
coins for use in cash transactions. On or before July 1, 2002, the participating
countries will withdraw all legacy bills and coins and use the Euro as their
legal currency.
 
                                       34
<PAGE>   38
 
     Our operating units located in European countries affected by the Euro
conversion intend to keep their books in their respective legacy currencies
through a portion of the transition period. At this time, we do not expect
reasonably foreseeable consequences of the Euro conversion to have a material
adverse effect on our business operations or financial condition.
 
CAUTIONARY FACTORS
 
     This report contains various forward-looking statements concerning our
prospects that are based on the current expectations and beliefs of management.
We may also make forward-looking statements from time to time in other reports
and documents as well as oral presentations. When used in written documents or
oral statements, the words "anticipate", "believe", "estimate", "expect",
"objective" and similar expressions are intended to identify forward-looking
statements. The statements contained in this report and such future statements
involve or may involve certain assumptions, risks and uncertainties, many of
which are beyond our control, that could cause our actual results and
performance to differ materially from what is expected. In addition to the
assumptions and other factors referenced specifically in connection with such
statements, the following factors, among others, could impact our business and
financial prospects:
 
     - Factors affecting our international operations, including relevant
       foreign currency exchange rates, which can affect the cost to produce our
       products or the ability to sell our products in foreign markets, and the
       value in U.S. dollars of sales made in foreign currencies. Other factors
       include our ability to obtain effective hedges against fluctuations in
       currency exchange rates; foreign trade, monetary and fiscal policies;
       laws, regulations and other activities of foreign governments, agencies
       and similar organizations; and risks associated with having major
       manufacturing facilities located in countries, such as Mexico, Hungary
       and Italy which have historically been less stable than the United States
       in several respects, including fiscal and political stability; risks
       associated with the recent economic downturn in Japan, Russia, other
       Asian countries and Latin America.
 
     - Factors affecting our ability to continue pursuing our current
       acquisition strategy, including our ability to raise capital beyond the
       capacity of our existing Credit Facilities or to use our stock for
       acquisitions, the cost of the capital required to effect our acquisition
       strategy, the availability of suitable acquisition candidates at
       reasonable prices, our ability to realize the synergies expected to
       result from acquisitions, and the ability of our existing personnel to
       efficiently handle increased transitional responsibilities resulting from

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
RISK MANAGEMENT
 
     We are exposed to market risk from changes in foreign currency exchange
rates and interest rates. To reduce our risk from these foreign currency rate
and interest rate fluctuations, we occasionally enter into various hedging
transactions. We do not anticipate material changes to our primary market risks
other than fluctuations in magnitude from increased or decreased foreign
currency denominated business activity or floating rate debt levels. We do not
use financial instruments for trading purposes and are not a party to any
leveraged derivatives.
 
FOREIGN EXCHANGE
 
     We have, from time to time, used foreign currency options to hedge our
exposure from adverse changes in foreign currency rates. Our foreign currency
exposure exists primarily in the French Franc, German Mark, Swiss Franc and the
Japanese Yen values versus the U.S. dollar. Hedging is accomplished by the use
of foreign currency options, and the gain or loss on these options is used to
offset gains or losses in the foreign currencies to which they pertain. Hedges
of anticipated transactions are accomplished with options that expire on or near
the maturity date of the anticipated transactions. There were no outstanding
foreign exchange
                                       36
<PAGE>   40
 
options at September 30, 1998. In October, 1998 we entered into twelve foreign
currency options to hedge our exposure to each of the aforementioned currencies.
These options have a notional value of $45.7 million and were purchased at a
cost of $0.3 million. These options are designed to protect us from potential
detrimental effects of a strengthening U.S. dollar in our second, third and
fourth quarters of fiscal 1999.
 
     In fiscal 1999, we expect our exposure to net income from our primary
foreign currencies to approximate the following:

</TABLE>
 
     As a result of these anticipated exposures, we have entered into a series
of options expiring at the end of the second, third and fourth quarters of
fiscal 1999 to protect ourselves from possible detrimental effects of foreign
currency fluctuations as compared to the second, third and fourth quarters of
1998. We accomplished this by taking approximately one-fourth of the exposure in
each of the foreign currencies listed above and purchasing a put option on that
currency (giving us the right but not the obligation to sell the foreign
currency at a predetermined rate). We purchase put options on the foreign
currencies at amounts approximately equal to our quarterly exposure. These
options expire on a quarterly basis, at an exchange rate approximately equal to
the prior year's corresponding quarter's actual exchange rate. At September 30,
1998, there were no outstanding foreign currency option contracts. In October
1998, we acquired the following put options:

INTEREST RATES
 
     We use interest rate swaps to reduce our exposure to interest rate
movements. Our net exposure to interest rate risk consists of floating rate
instruments whose interest rates are determined by the London Interbank Offer
Rate ("LIBOR"). Interest rate risk management is accomplished by the use of
swaps to create fixed debt amounts by resetting LIBOR loans concurrently with
the rates applying to the swap agreements. At September 30, 1998, we had
floating rate debt of approximately $801.25 million of which a total of $325
million was swapped to fixed rates. In October 1998, we entered into an
additional swap agreement with a notional amount of $50 million. The net
interest rate paid by us is approximately equal to the sum of the swap agreement
rate plus the applicable LIBOR Margin. During all of 1998, the LIBOR Margin was
 .75%. The swap agreement rates and durations as of December 1, 1998 are as
follows:

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
Sybron International Corporation:
 
     We have audited the accompanying consolidated balance sheets of Sybron
International Corporation and subsidiaries as of September 30, 1997 and 1998,
and the related consolidated statements of income, shareholders' equity, and
cash flows for each of the years in the three-year period ended September 30,
1998. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements 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 financial position of Sybron
International Corporation and subsidiaries as of September 30, 1997 and 1998,
and the results of their operations and their cash flows for each of the years
in the three-year period ended September 30, 1998, in conformity with generally
accepted accounting principles.

               SYBRON INTERNATIONAL CORPORATION AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
             FOR THE YEARS ENDED SEPTEMBER 30, 1996, 1997 AND 1998
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The subsidiaries of Sybron International Corporation are leading
manufacturers of value-added products for the laboratory and professional dental
and orthodontic markets in the United States and abroad. The Company's
laboratory subsidiaries manufacture products for the Labware and Life Sciences,
Clinical and Industrial Technologies, Diagnostic and Microbiology and Laboratory
Equipment markets. The Company's dental subsidiaries manufacture products for
the Professional Dental market and the Orthodontic market.
 
  (a) Principles of Consolidation and Fiscal Year End
 
     The consolidated financial statements reflect the accounts of Sybron
International Corporation and its subsidiaries. The term "Company" or "Sybron"
as used herein refers to Sybron International Corporation and its subsidiaries
and their respective predecessors, unless the context otherwise requires. All
significant intercompany balances and transactions have been eliminated. The
Company's fiscal year ends on September 30. The fiscal years ended September 30,
1996, 1997 and 1998 are hereinafter referred to as "1996", "1997" and "1998",
respectively. In April, 1998, LRS Acquisition Corp. merged with a subsidiary of
the Company formed for that purpose (the "LRS Merger"). The LRS Merger was
accounted for as a pooling of interests. As such, all financial statements and
accompanying notes have been restated as if the LRS Merger took place on October
1, 1994, the first full year of LRS' operations.
 
  (b) Cash Equivalents
 
     For purposes of reporting cash flows, cash and cash equivalents include
investments in debt obligations with original maturities of three months or
less.
 
  (c) Inventories
 
     Inventories are stated at the lower of cost or market. Certain domestic
inventories of approximately $92,530 and $91,544 at September 30, 1997 and 1998,
respectively, are valued on the last-in, first-out (LIFO) method. The remaining
inventories are valued on the first-in, first-out (FIFO) method.
 
  (d) Property, Plant and Equipment
 
     Property, plant and equipment are stated at cost less accumulated
depreciation. Depreciation is provided over the estimated useful lives of
depreciable assets (5 to 45 years for land improvements, buildings and building
improvements, and 3 to 12 years for machinery and equipment) using the
straight-line method. The Company assesses the recoverability of assets by
comparing the carrying amount of an asset to future net cash flows expected to
be generated by that asset. If such assets are considered impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair market value of the assets.
 
  (e) Intangible Assets
 
     Intangible assets are recorded at cost and are amortized, using the
straight-line method, over their estimated useful lives. Excess cost over net
asset value acquired (goodwill) and trademarks are amortized over 40 years;
proprietary technology and other intangibles are amortized over 7 to 17 years.
The Company assesses the recoverability of its goodwill by determining whether
the amortization of the goodwill balance over its remaining life can be
recovered through projected undiscounted future cash flows of the acquired
businesses. If projected future cash flows indicate that unamortized goodwill
will not be recovered, an adjustment would be made to reduce the net goodwill to
an amount equal to projected future cash flows discounted at the
 
                                       45

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Company's incremental borrowing rate. Cash flow projections are based on trends
of historical performance and management's estimate of future performance,
giving consideration to existing and anticipated competitive and economic
conditions.
 
  (f)  Revenue Recognition
 
     The Company recognizes revenue upon shipment of products.
 
  (g)  Income Taxes
 
     Income taxes are accounted for under the asset and liability method wherein
deferred tax assets and liabilities are recognized for future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.
 
  (h) Research and Development Costs
 
     Research and development costs are charged to selling, general and
administrative expenses in the year they are incurred. Research and development
costs for 1996, 1997 and 1998 were approximately $15,162, $15,820 and $16,140,
respectively.
 
  (i)  Foreign Currency Translation
 
     The functional currency for the Company's foreign operations is the
applicable local currency. The translation from the applicable foreign
currencies to U.S. dollars is performed for balance sheet accounts using current
exchange rates in effect at the balance sheet date and for revenue and expense
accounts using a weighted average exchange rate during the period. The gains or
losses, net of applicable deferred income taxes, resulting from such
translations are included in shareholders' equity. Gains and losses resulting
from foreign currency transactions are included in net income. Foreign currency
transaction losses for 1996, 1997 and 1998 were approximately $493, $4,269 and
$1,116, respectively.
 
  (j)  Pensions
 
     The Company and its subsidiaries have various pension plans covering
substantially all employees. U.S. and Canadian pension obligations are funded by
payments to pension fund trustees. Other foreign pensions are funded as expenses
are incurred. The Company's policy is generally to fund the minimum amount
required under the Employee Retirement Income Security Act of 1974, as amended,
for plans subject thereto.
 
  (k)  Earnings Per Common Share
 
     In 1998, the Company adopted Statement of Financial Accounting Standards
No. 128 "Earnings Per Share". This change required the Company to report both
basic and diluted earnings per common share. Basic earnings per common share is
calculated by dividing net income by the weighted average number of common
shares outstanding in the period presented. Diluted earnings per common share is
calculated by dividing net income by the weighted average number of common
shares outstanding plus dilutive effects of potential common shares outstanding
during the period. The weighted average number of common shares for the basic
earnings per common share calculations were 97,729, 98,660 and 100,423 in 1996,
1997 and 1998, respectively. The weighted average number of common shares
(including potential dilutive common shares) used in the diluted earnings per
common share calculations were 100,098, 102,172 and 103,964 shares in 1996,
 
                                       46
<PAGE>   50
               SYBRON INTERNATIONAL CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
1997 and 1998, respectively. The difference between the number of shares used in
this calculation is due to the effect of stock options.
 
  (l)  Deferred Financing Fees
 
     Deferred financing fees are capitalized and amortized as a separate
component of other income over the life of the related debt agreements.
 
  (m)  Advertising Costs
 
     Advertising costs included in selling, general and administrative expenses
are expensed as incurred and were $10,991, $10,729 and $10,361 in 1996, 1997 and
1998, respectively.
 
  (n) Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  (o) Derivative Financial Instruments
 
     Derivative financial instruments are used by the Company in the management
of its interest rate and foreign currency exposures.
 
     The Company uses interest rate swaps to manage its interest rate risk. The
net amounts to be paid or received under interest rate swap agreements
designated as hedges are accrued as interest rates change and are recognized
over the life of the swap agreements, as an adjustment to interest expense from
the underlying debt to which the swap is designated. The related amounts payable
to, or receivable from, the counterparties are included in other current assets
or other current liabilities.
 
     The Company, from time to time, enters into foreign exchange options
relating to the anticipated cash flow in local currencies of certain foreign
operations. These options allow the Company to exchange foreign currencies for
U.S. dollars. The Company had no foreign exchange option contracts at September
30, 1997 or 1998.
 
     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"), which is effective for financial statements for periods beginning after
December 15, 1999. SFAS 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts and hedging activities. The Company intends to adopt SFAS 133 in
the first quarter of fiscal year 2001. The Company does not believe the adoption
of SFAS 133 will have a material impact on the financial statements.
 
  (p) Environmental Expenditures
 
     Environmental expenditures that relate to current ongoing operations or to
conditions caused by past operations are expensed. The Company determines its
liability on a site by site basis and records a liability at the time when the
liability is probable and can be reasonably estimated. The estimated liability
is not reduced for possible recoveries from insurance carriers.

(2) BUSINESS AND CREDIT CONCENTRATIONS
 
     Many of the Company's products are sold through major distributors, two of
which have exceeded 10% of our consolidated net sales in prior years. These two
distributors accounted for approximately 12% and 10% of the Company's net sales
in 1996, 10% and 7% of the Company's net sales in 1997, and 9% and 7% of the
Company's net sales in 1998. Accounts receivable from these distributors
comprised approximately 16% of the outstanding consolidated accounts receivable
balances at both September 30, 1997 and 1998. (see note 15)
 
(3) INVENTORIES
 
     Inventories at September 30, 1997 and 1998 consist of the following:

     The valuation allowance for deferred tax assets as of October 1, 1997 was
$7,582. The net change in the total valuation allowance for the years ended
September 30, 1997 and 1998 was a decrease of $1,481 and $3,042, respectively.
In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. Management considers the
scheduled reversal of deferred tax liabilities, projected future taxable income
and tax planning strategies in making this assessment.
 
     Tax benefits relating to the income tax benefit of stock options reported
in the consolidated statements of income have been reclassed to additional
paid-in capital for the years September 30, 1996, 1997 and 1998.
 
     At September 30, 1998, the Company has an aggregate of $2,500 of foreign
net operating loss carry forwards from certain foreign jurisdictions which
expire between 2000 and 2003. The Company has an aggregate of $13,000 of various
state net operating losses, the majority of which expire between 2002 and 2007.
 
     Accumulated earnings of foreign subsidiaries at September 30, 1996, 1997
and 1998 of approximately $22,000, $22,000 and $26,000, respectively, have been
reinvested in the business and no provision for income taxes has been made for
the repatriation of these earnings.

issued Statement of Position 98-1 ("SOP 98-1"), "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use", which specifies the
accounting treatment provided for computer software costs depending upon the
type of cost incurred. This statement is effective for our fiscal year 2000

     THE 1995 REFINANCING:  On July 31, 1995, the Company and its domestic
subsidiaries entered into a new credit agreement (the "Credit Agreement") with
Chemical Bank (now known as The Chase Manhattan Bank ("Chase")) and certain
other lenders providing for a term loan facility of $300,000 (the "Term Loan
Facility"), and a revolving credit facility of $250,000 (the "Revolving Credit
Facility"; collectively, the "Credit Facilities"). The Company borrowed $300,000
under the Term Loan Facility and approximately $122,500 under the Revolving
Credit Facility. Approximately $158,500 of the borrowed funds were used to
finance the acquisition of Nunc (approximately $9,100 of the acquisition price
for Nunc had been borrowed under previous credit facilities). The remaining
borrowed funds of approximately $264,000 were used to repay outstanding amounts,
including accrued interest, under the Company's previous credit facilities and
to pay certain fees in connection with such refinancing. On July 9, 1996, under
the First Amendment to the Credit Agreement (the "First Amendment"), the
Revolving Credit Facility was increased to $300,000 and a competitive bid
process was added as an option to the Company in setting interest rates. On
April 25, 1997, the Company entered into the Second Amended and Restated Credit
Agreement (the "Second Amendment"). The Second Amendment was an expansion of the
Credit Facilities. The Term Loan Facility was restored to $300,000 by increasing
it by $52,500 (equal to the amount previously repaid through April 24, 1997) and
the Revolving Credit Facility was expanded from $300,000 to $600,000. On April
25, 1997, the Company borrowed a total of $622,900 under the Credit Facilities.
The proceeds were used to repay $466,300 of previously existing loans (including
accrued interest and certain fees and expenses) under the Credit Facilities and
to pay $156,600 with respect to the purchase of Remel Limited Partnership which
includes both the purchase price and payment of assumed debt. The $72,000 of CAF
(as defined below) borrowings remained in place. On July 1, 1998, the Company
completed the First Amendment to the Second Amended Credit Agreement (the
"Additional Amendment"). The Additional Amendment provided for an increase in
the Term Loan Facility of $100,000. The proceeds of the Additional Amendment
were used to repay $100,000 of debt outstanding under the Revolving Credit
Facility. The transactions described above, including the First, Second and
Additional Amendments, are referred to as the "1995 Refinancing".
 
     In connection with the Second Amendment, the Company wrote off as an
extraordinary item approximately $1,086 ($673 net of tax) in 1997, consisting of
unamortized deferred financing fees.
 
     TERM LOAN FACILITY:  Borrowings under the Term Loan Facility are required
to be repaid in 21 consecutive quarterly installments of principal. Total
payments of $43,750 have been made to satisfy amounts due in 1997 and 1998.
Remaining annual payments are due as follows: $36,250 in fiscal 1999, $42,500 in
fiscal 2000, $53,750 in fiscal 2001 and $223,750 in fiscal 2002.
 
     In addition, the Company is required to further retire the principal amount
of borrowings under the Term Loan Facility (and then the Revolving Credit
Facility) with proceeds from borrowings other than from the Credit Facilities
exceeding certain amounts, and with proceeds from certain asset sales not in the
ordinary

course of business. Borrowings under the Term Loan Facility (and the Revolving
Credit Facility) are secured by the capital stock of the Company's domestic
subsidiaries, and by 65% of the stock held by the domestic subsidiaries in their
direct foreign subsidiaries. The Term Loan Facility provides for an annual
interest rate, at the option of the Company, equal to (a) the higher of (i) the
rate from time to time publicly announced by Chase in New York City as its prime
rate, (ii) the federal funds rate plus 1/2 of 1%, and (iii) the base CD rate
plus 1% (collectively referred to as "ABR") or (b) the London interbank offered
rate ("LIBOR") plus 1/2% to 7/8% (the "LIBOR Margin") depending upon the ratio
of the Company's total debt to Consolidated Adjusted Operating Profit (as
defined).
 
     As of September 30, 1998, the Company has six interest rate swaps
outstanding aggregating a notional amount of $325,000. The net interest rate
paid by the Company is approximately equal to the sum of the swap agreement rate
plus the applicable LIBOR Margin. During 1998, the LIBOR Margin was .75%. The
swap agreement rates and duration are as follows:

</TABLE>
 
     The Company's risk with regard to the swaps is limited to the
counterparty's (Bank of America, Illinois, with a notional amount of $175,000,
and The Sumitomo Bank Limited, The Bank of Nova Scotia and The Bank of New York
with notional amounts of $50,000 each) ability to meet the payment terms of the
contract. All interest expense for all debt is calculated using the interest
method. On October 23, 1998, the Company entered into an additional Swap
Agreement with Bank of Tokyo-Mitsubishi in the notional amount of $50 million.
The Agreement expires on July 31, 2002, and has a swap interest rate of 4.733%.
 
     The Credit Agreement contains numerous financial and operating covenants,
including, among other things: restrictions on investments; requirements that
the Company maintain certain financial ratios; restrictions on the ability of
the Company and its subsidiaries to create or permit liens, or to pay dividends
or make other restricted payments (as defined) in excess of $50,000 plus 50% of
the defined consolidated net income of the Company for each fiscal quarter
ending after June 30, 1995, less any dividends paid or other restricted payments
made after June 22, 1994; and limitations on incurrence of additional
indebtedness.
 
     REVOLVING CREDIT FACILITY:  In 1995 and 1996 and until April 25, 1997, the
Company paid a commitment fee of .375% per year on the average unused portion of
the commitments under a previous revolving credit facility and the Revolving
Credit Facility, with the ability to reduce the amount to .25% if certain
financial criteria were met. After April 25, 1997, the commitment fee was
reduced to .20% with the ability to increase or reduce the amount from .225% to
 .15% depending upon the ratio of the Company's total debt to Consolidated
Adjusted Operating Profit. The Revolving Credit Facility also provides for the
issuance of standby letters of credit and commercial letters of credit on behalf
of the Company's subsidiaries as required in the ordinary course of business as
part of the working capital line. Borrowings under the Revolving Credit Facility
bear interest on the same terms as those under the Term Loan Facility described
above, except that the Company has a third option to set the rate by a
competitive bid process among the parties to the Revolving Credit Facility (the
"CAF"). The Revolving Credit Facility term expires on August 16, 2002.
 
     The Company paid fees on the average unused portion of credit commitments
under a previous revolving credit facility and the Revolving Credit Facility of
approximately $234, $328 and $327 in 1996, 1997 and 1998, respectively. The
Company paid fees of approximately $60, $47 and $55 for standby letters of
credit under a

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
previous revolving credit facility and the Revolving Credit Facility in 1996,
1997 and 1998, respectively. Standby letters of credit were approximately $5,155
and $5,108 at September 30, 1997 and 1998, respectively.
 
     SALE/LEASEBACK:  On December 22, 1988, the Company completed the sale and
leaseback (the "Sale/ Leaseback") of its then principal domestic manufacturing
and office facilities with an unaffiliated third party. The proceeds of $22,500
(net of approximately $1,100 in fees) were used to retire debt. The transaction
has been accounted for as a financing for financial statement purposes and as a
sale for income tax purposes. The financing obligation is being amortized over
the initial 25-year lease term.
 
     The Company pays all costs of maintenance and repair, insurance, taxes, and
all other expenses associated with the properties. In addition, each of the
leases is unconditionally guaranteed by the Company.
 
     The initial term of each lease is 25 years with five five-year renewal
options. The initial aggregate annual payments under the leases were $2,879
payable monthly in advance. On the fifth anniversary of the leases and every
five years thereafter (including renewal terms), the rent is increased by the
percentage equal to 75% of the percentage increase in the Consumer Price Index
over the preceding five years. The percentage increase to the rent in any
five-year period will be capped at 15%. Beginning January 1, 1994, annual
payments increased to $3,311. The next adjustment will not occur until January
1, 1999.
 
     Under the terms of the Sale/Leaseback, the Company is not permitted to pay
dividends with respect to its Common Stock in excess of 50% of: (a) its total
consolidated net income (as defined) earned since September 1, 1988 through the
fiscal quarter ended prior to the payment of the dividend, plus (b) the
aggregate net proceeds of the sale of the Company's capital stock after December
1988.
 
     The Company has the option to purchase the facilities according to the
terms of any bona fide offer received by the lessor from a third party (the
"Third Party Offer") at any time during the term of the leases. The purchase
price upon exercise of the option will be an amount equal to the purchase price
contained in the Third Party Offer.
 
     In the event of a breach of certain covenants which include, subject to
certain exceptions, restrictions on the Company's and its subsidiaries'
incurrence of certain additional indebtedness, payment of dividends or the
making of other distributions or the repurchase of the Company's capital stock,
or the creation of liens on their respective properties, the Company must cause
each subsidiary to make a rejectable offer to the lessor to purchase its
facility. If the lessor accepts the rejectable offer, each subsidiary will pay
to the lessor a formula price based upon the lessor's equity in the property and
the lessor's pre-payment premium to its lender. The Company may also be
obligated to repurchase the property upon the occurrence of certain other
events.
 
     DEBT ASSUMED IN LRS MERGER:  In connection with the LRS Merger, the Company
assumed debt. Such debt totaled $34,311 at September 30, 1997. This amount
consisted of senior debt of $14,450 at an annual rate of 9.75%, $18,000 of
subordinated debt at an annual rate of 12% and other debt of $1,861 primarily
pertaining to various capital leases and a mortgage. Both the senior and
subordinated debt were payable to certain stockholders of LRS. All of these
financing arrangements were extinguished simultaneously with the LRS Merger.

(9) DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts of financial instruments approximate fair value due to
the short maturity of those instruments except as follows:
 
  Long-Term Debt
 
     TERM LOAN FACILITY AND REVOLVING CREDIT FACILITY.  The fair value was
determined by estimating the interest rate margins (the premium over LIBOR) on
both the Term Loan Facility and the Revolving Credit Facility for companies with
credit risk similar to that of the Company. In 1998 the Company's spread over
LIBOR was 75 basis points.

               SYBRON INTERNATIONAL CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     SALE/LEASEBACK.  The fair value was determined by estimating the interest
rate at which the Company could refinance the Sale/Leaseback given the same
maturity period.
 
  Interest Rate Swap Agreements
 
     The fair values of interest rate swap agreements are obtained from dealer
quotes. These values represent the estimated amount the Company would pay if the
agreements were terminated as quoted by the bank with which the Company executed
the swap agreements.

(10) EMPLOYEE BENEFIT PLANS
 
     PENSION PLANS:  The Company has defined benefit pension plans covering
approximately 71 percent of U.S. employees. The benefits are generally based on
various formulas, the principal factors of which are years of service and
compensation. The Company's funding policy is to generally make the minimum
annual contributions required by applicable regulations. However, in 1996 and
1997, the Company funded additional special cash contributions of $962 and $793.
Such contributions were made to avoid the variable rate portion of the Pension
Benefit Guaranty Corporation insurance premium for such years.
 
     The following table sets forth the plans' funded status and amounts
recognized in the Company's consolidated balance sheets for 1997 and 1998 for
its U.S. and Canadian pension plans:

     SAVINGS PLANS:  Employees in the United States are eligible to participate
in contributory savings plans maintained by the Company under Section 401(k) of
the Internal Revenue Code of 1986, as amended (the "Code"). Company matching
contributions under the plans, net of forfeitures, were approximately $2,016,
$2,805 and $3,401 for 1996, 1997 and 1998, respectively.
 
     POSTRETIREMENT HEALTH CARE PLANS:  In addition to providing pension
benefits, the Company provides certain health care benefits for eligible retired
employees which are funded as costs are incurred. Certain employees who reached
the age of 55 prior to January 1, 1996, will become eligible for these benefits
if they reach retirement age while working for the Company. The Company accrues,
as current costs, the future lifetime retirement benefits for both qualifying
active and retired employees and their dependents. The postretirement health
care plans for subsidiaries of the Company and certain divested operations are
generally contributory, with retiree contributions adjusted annually. In 1986,
the Company instituted a policy with respect to postretirement medical premiums
where the Company's contributions were frozen at the levels equal to the
Company's contribution on December 31, 1988, except where collective bargaining
agreements prohibited such a freeze.
 
     The following table sets forth the postretirement plans' status as shown in
the Company's consolidated balance sheets at September 30, 1997 and 1998.

</TABLE>
 
     The weighted-average discount rate used in determining the net periodic
benefit cost was 7.5%, 7.75% and 7.5% in 1996, 1997 and 1998, respectively. The
weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 7.75%, 7.5% and 6.75% in 1996, 1997 and
1998, respectively. The assumed average inflation rate of medical costs over the
life of the benefits was 5.5% in 1996, 1997 and 1998.
 
     An increase of one percentage point in the per capita cost of health care
costs associated with the plans for which the Company contributions are not
frozen would increase the accumulated postretirement benefit obligation and
service and interest cost components as of September 30, 1998 by approximately
$815 and $79, respectively.
 
     Because the majority of the postretirement plans are remaining liabilities
from certain divested operations and more than 80% of the 1996, 1997 and 1998
net periodic postretirement benefit costs relate to interest costs, the Company
has classified such interest costs as interest expense. This results in a
non-cash increase in interest expense of approximately $985, $933 and $932 in
1996, 1997 and 1998, respectively.
 
     In February 1998, the FASB issued Statement of Financial Accounting
Standards No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits,"("SFAS 132") which revises disclosures about pensions
and other postretirement benefit plans. SFAS 132 will be effective for fiscal
year 1999 financial statements and restatement of disclosures for earlier years
will be required unless the information is not readily available. The Company is
currently evaluating the extent to which the Company's financial statements will
be affected by SFAS 132.
 
(11) RESTRUCTURING AND MERGER AND INTEGRATION CHARGES
 
     In March 1996, the Company recorded a restructuring charge of $8,277
($6,087 after tax or $.06 per share on a diluted basis) for the rationalization
of certain acquired companies, combination of certain production facilities,
movement of certain customer service and marketing functions, and the exiting of
several product lines. The restructuring charge has been classified as
components of cost of sales ($2,223), selling, general and administrative
expenses ($5,307) and income tax expense ($747). Principal items included in the
reserve were severance and termination costs for approximately 130 notified
employees (primarily production, sales and marketing personnel) (approximately
$2,300), remaining lease payments and shut down costs on exited facilities
(approximately $2,100), the non-cash write-off of certain fixed assets and
inventory associated with exited product lines, primarily at Sybron Dental
Specialties (approximately $2,500), a statutory tax penalty (approximately $750)
and other related restructuring costs (approximately $650). As of September 30,
1998, the Company has made substantially all cash payments of approximately
$6,177 and has written off approximately $2,100 of fixed assets and inventory
relating to the restructuring reserve.
 
     In June 1998, the Company recorded a restructuring charge of $24,024
($16,703 after tax or $.16 per share on a diluted basis) for the rationalization
of certain acquired companies, combination of certain production facilities,
movement of certain customer service and marketing functions, and the exiting of
several product lines. The restructuring charge has been classified as
components of cost of sales ($6,416), selling,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
general and administrative expenses ($16,924) and income tax expense ($684).
Principal items included in the reserve were severance and termination costs for
approximately 165 notified employees (primarily production, sales and marketing
personnel) (approximately $8,477), the non-cash write-off of certain fixed
assets and inventory associated with exited product lines (approximately
$8,710), the non cash write-off of goodwill associated with discontinued product
lines (approximately $2,061), remaining lease payments and shut down costs on
exited facilities and other contractual obligations (approximately $1,991), a
statutory tax penalty (approximately $684), and other related restructuring
costs (approximately $2,101). As of September 30, 1998, the Company has made
cash payments of approximately $4,561 and has written off approximately $11,422
of fixed assets, inventory, goodwill and other miscellaneous items relating to
the restructuring reserve. The remaining amount of approximately $8,041 relates
to obligations primarily expected to be paid in the next twelve months.
Remaining obligations at September 30, 1998 include approximately $5,244 of
severance and termination costs to notified employees, $684 for a statutory tax
penalty, $648 for contractual obligations, $644 for statutory obligations and
$821 for other related restructuring costs.
 
     In 1998, the Company incurred approximately $10,507 ($6,400 after tax or
$.06 per share on a diluted basis) of costs associated with the merger,
transition and integration of the "A" Company (See note 14). The majority of
these expenses were adjustments to the merger consideration. The Company expects
to incur an estimated additional $0.7 million before taxes in the first, second
and third quarters of fiscal 1999 in connection with further integration costs.
 
(12) CAPITAL STOCK
 
     In 1992, the Company entered into a shareholders agreement with H&H/Sybron
Partners, L.P., Hicks & Haas Incorporated, DLJ Capital Corporation, Thomas O.
Hicks and Robert B. Haas, and certain of the executive officers of the Company
that became effective on May 14, 1992. Such agreement grants certain demand and
piggy-back registration rights to the parties thereto with respect to certain
shares of common stock owned by such parties. DLJ Capital Corporation
effectively is no longer a party to this agreement because it has sold all of
the Common Stock of the Company held by it which was subject to the agreement.
 
     STOCK OPTION PLANS:  The Company has four stock option plans. As of
September 30, 1998, there were options with respect to 12,786 shares of Common
Stock outstanding under the 1988 Stock Option Plan (the "1988 Plan"), and there
were no shares available for the granting of options under such plan; there were
options with respect to 37,064 shares of Common Stock outstanding under the 1990
Stock Option Plan (the "1990 Plan") and there were 2,936 shares remaining
available for the granting of options under such plan; there were options with
respect to 9,024,178 shares of Common Stock outstanding under the Amended and
Restated 1993 Long-Term Incentive Plan (the "1993 Plan") and there were
2,106,036 shares remaining available for the granting of options under such
plan; and there were options with respect to 324,000 shares of Common Stock
outstanding under the Amended and Restated 1994 Outside Directors' Stock Option
Plan (the "Outside Directors' Plan"). The Outside Directors' Plan expired in
September 1998 with respect to

     The range of exercise prices for options outstanding at September 30, 1998
was $5.99 to $24.50. The range of exercise prices for options is wide due to the
increasing price of the Company's stock (upon which the exercise price is based)
over the period of the grants.

  1988, 1990 and 1993 Plans
 
     No options may be granted under the plans after ten years from the date the
plans are approved by the shareholders of the Company. Options granted pursuant
to the plans shall be either incentive options which are intended to meet the
requirements of section 422 of the Code or nonstatutory options. The exercise
price of the options will be determined by the Compensation/Stock Option
Committee. The exercise price of any incentive option shall not be less than the
fair market value per share of the Common Stock on the date of the grant of such
option. An optionee under the plans must pay the full option price of an option
either (i) in cash
 
                                       60

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
or its equivalent, (ii) with the Compensation/Stock Option Committee's consent,
by delivering previously acquired shares of Common Stock having a fair market
value at the time of the exercise equal to the total option price, (iii) with
the Compensation/Stock Option Committee's consent, by a cashless exercise as
permitted under The Federal Reserve Board's Regulation T or (iv) in any
combination of the foregoing.
 
     With respect to the options granted prior to May 14, 1992 under the 1990
Plan, all of the shares purchased under such nonstatutory options were deemed to
have been vested no later than May 14, 1993, the first anniversary of the
Company's public offering of shares of common stock on May 14, 1992. With
respect to options granted under the 1990 Plan after May 14, 1992, and with
respect to options granted under the 1993 Plan, the options vest in equal annual
installments on each of the first four anniversaries following the date of
grant.
 
  Outside Directors' Plan
 
     The Outside Directors' Plan provided for the automatic granting of
nonstatutory stock options to those of the Company's directors who qualify as
"outside directors" at the time of grant. Following each annual meeting of
shareholders prior to September 30, 1998, the plan's expiration date, each
outside director was automatically granted an option to purchase 12,000 shares
of Common Stock at an exercise price equal to the fair market value of the
Common Stock on the date of grant. Each option granted under the Outside
Directors' Plan becomes exercisable six months after the date of grant,
regardless of whether the grantee is still a director of the Company on such
date. All rights to exercise an option granted under the Outside Directors' Plan
terminate upon the earlier of ten years from the date of grant or two years from
the date the grantee ceases to be a director of the Company. The exercise price
must be paid in full at the time of exercise, and such payment may be made in
cash, by delivering shares of Common Stock which the optionee or the optionee's
spouse or both have beneficially owned for at least six months prior to the time
of exercise, or through a combination of cash and such delivered Common Stock.
 
     The Company has adopted the provisions of Statement of Accounting Standards
No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), and continues
to apply Accounting Principles Board Opinion No. 25 and related interpretations
in accounting for its stock plans. If the Company had elected to recognize
compensation cost for all of the plans based upon the fair value at the grant
dates for awards under those plans, consistent with the method prescribed by
SFAS 123, net income and earnings per share would have been changed to the pro
forma amounts indicated below:

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options that 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

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Company's options have characteristics significantly different from traded
options, and because changes in the subjective input assumptions can materially
affect the fair value estimate, in the opinion of management, the existing
models do not necessarily provide a reliable single value of its options and may
not be representative of the future effects on reported net income or the future
stock price of the Company. The weighted average estimated fair value of
employee stock options granted in 1996, 1997 and 1998 was $5.64, $7.75 and
$13.13 per share, respectively. For purposes of pro forma disclosure, the
estimated fair value of the options is amortized to expense over the options'
vesting period.
 
     EQUITY RIGHTS:  As of September 30, 1998, the Company holds 220 shares of
treasury stock for delivery to equity right holders who have not yet surrendered
their certificates. Equity right holders are entitled to receive 4.375 shares of
Common Stock upon surrender of such certificates.
 
(13) COMMITMENTS AND CONTINGENT LIABILITIES
 
     The Company or its subsidiaries are at any one time parties to a number of
lawsuits or subject to claims arising out of their respective operations, or the
operation of businesses divested in the 1980's for which certain subsidiaries
may continue to have legal or contractual liability, including products
liability, workplace safety and environmental claims and cases, some of which
involve claims for substantial damages. The Company and its subsidiaries are
vigorously defending lawsuits and other claims against them. Based upon the
insurance available under an insurance program and the potential for liability
with respect to claims which are uninsured, the Company believes that any
liabilities which might foreseeably result from any of the pending cases and
claims would not have a material adverse effect on the results of operations or
financial condition of the Company. There can be no assurance as to this,
however, or that litigation having such a material adverse effect will not arise
in the future.
 
     A subsidiary of the Company has been identified as a potentially
responsible party ("PRP") at the Aqua-Tech site in South Carolina (the
"Aqua-Tech Site") with respect to a previously owned facility. An action has
been conducted at the Aqua-Tech Site for the removal of surface contaminants
under the supervision of the Environmental Protection Agency ("EPA") under the
Comprehensive Environmental Response, Compensation and Liability Act of 1980, as
amended ("CERCLA"). The Company's total contribution to such effort, which has
been paid, was approximately $46. The site has been placed by the EPA on the
federal National Priority List under CERCLA, which is a prerequisite to any
federally-mandated requirement for long-term remedial work at the site under
CERCLA, such as would be involved in soil and groundwater remediation. The
Company is participating with a PRP group composed of approximately 100 parties
in an agreement with the EPA to undertake a remedial investigation and
feasibility study which will be used by the EPA to determine what remedy, if
any, should be required at the site. This study is expected to be completed in
1999. Because the study, which involves extensive testing required to
characterize the existence, extent and nature of any contamination to determine
potential remedies, has not yet been completed, an estimate of the Company's
potential liability cannot be made. However, although CERCLA does provide for
joint and several liability, because the Company's share of waste allegedly sent
to the site is reportedly not more than 1% of the total waste sent, the Company
believes any ultimate liability will not have a material adverse effect on the
Company's results of operations or financial condition.
 
     On May 2, 1996, Combustion Engineering, Inc. ("CE") commenced legal
proceedings (the "CE Litigation") against the Company with respect to the former
Taylor Instruments facility in Rochester, New York (the "Site"), an operation
accounted for as a discontinued operation when the decision was made to exit the
industrial capital goods business in 1983. The CE Litigation, brought in the New
York Supreme Court, Monroe County, New York, related to claims CE made for
reimbursement to it of expenses associated with the remediation of alleged
environmental contamination at the Site. The Site was sold to CE in 1983 by the
predecessor of a subsidiary of the Company. The Company settled the CE
Litigation on November 16, 1998. Under the settlement agreement, the Company
agreed to pay up to $10,000 for remediation of contamination
 
                                       62

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
located on the Site. $8,500 was paid on the date of settlement. Up to an
additional $1,500 will be paid if, and to the extent that, the future cost of
on-Site remediation exceeds $5,500. In exchange, CE has agreed to be responsible
for and to indemnify the Company with respect to the remediation of on-Site
contamination. The settlement agreement also provides that Sybron will assume
control over and be responsible for the remediation of any potential
contamination located off-Site. The Company's results for 1998 reflect a pre-tax
charge of $12,500 related to the settlement. The charge includes the Company's
estimate, based in part on an analysis provided by a consultant to the Company,
of the costs associated with the remediation of off-Site contamination. Based on
current information, off-Site remediation may include a soil vapor monitoring
program and the clean-up of mercury contaminated sediments in sewers close to
the Site.
 
(14) ACQUISITIONS
 
     The Company has completed 47 acquisitions since the beginning of 1996
(including three mergers and a joint venture). The acquired companies are all
engaged in businesses related to the laboratory or dental segments of the
Company or use a process in manufacturing which is similar to the Company's
existing businesses.
 
     1996
 
     During 1996, the Company completed ten acquisitions at an aggregate
purchase price including earnout provisions paid subsequent to September 30,
1996 of approximately $108,402, including fees and expenses. The Company may be
subject to future purchase price adjustments based upon earnout provisions under
certain of the purchase and sale agreements. Such earnout provisions which apply
to the 1996 acquisitions aggregate a maximum potential remaining payout of
approximately $3,191. Earnout provisions are subject to the achievement of
certain financial goals. Earnouts, if achieved, are payable in the years 1999
through 2001. All acquisitions were accounted for as purchases. The results of
the acquisitions were included as of the date they were acquired. The following
unaudited table outlines sales and operating income for the most recent
available twelve-month period prior to acquisition, and total assets at the most
recent available date prior to acquisition, for each of the acquired companies.

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
Sybron International Corporation:
 
     On November 16, 1998, we reported on the consolidated balance sheets of
Sybron International Corporation and subsidiaries as of September 30, 1997 and
1998, and the related consolidated statements of income, shareholders' equity,
and cash flows for each of the years in the three-year period ended September
30, 1998, which are included in the 1998 Annual Report on Form 10-K. In
connection with our audits of the aforementioned consolidated financial
statements, we also audited the related financial statement schedule as listed
in Item 14. This financial statement schedule is the responsibility of the
Company's management. Our responsibility is to express an opinion on the
financial statement schedule based on our audits.
 
     In our opinion, such financial statement schedule, when considered in
relation to the basic consolidated financial statements taken as a whole,
presents fairly, in all material respects, the information set forth therein.

                               SYBRON CORPORATION
                           DEFERRED COMPENSATION PLAN


1.       Purposes

         Sybron Corporation (the "Company") has adopted this Deferred
Compensation Plan (the "Plan") for the benefit of key employees (the
"Participants") of the Company or its subsidiaries who wish to defer the receipt
of eligible earnings which they may otherwise be entitled to receive from the
Company. The purposes of the Plan are to assist Participants with their
individual tax and retirement income planning and to permit the Company to
remain competitive in attracting, retaining, motivating and rewarding key
employees.

2.       Plan Administrator

         The Plan shall be administered by the Compensation/Stock Option
Committee of the Board of Directors of the Company (the "Administrator"). The
Administrator shall have all authority that may be appropriate for administering
the Plan, including adopting rules and regulations for carrying out the Plan,
interpreting the provisions of the Plan and determining the eligibility of
employees to participate in the Plan, the types of compensation that may be
deferred and a Participant's entitlement to benefits. No member of the
Administrator shall act on any matter relating specifically to himself.

3.       Eligibility

         This Plan covers only a select group of management or highly
compensated employees of the Company or its subsidiaries as designated from time
to time by the Administrator. The Plan will initially cover Company officers and
subsidiary presidents.

4.       Amount of Deferral

         The Administrator shall identify which types of compensation are
eligible for deferral under the Plan. The Administrator may establish limits
regarding the amount or percentages of compensation that may be deferred (e.g.
10-50% of base salary).

5.       Time for Electing Deferral

         An election to defer any eligible compensation earned after the fiscal
year ending September 30, 1993 shall be made prior to the time that the services
to which the compensation relates are performed. An election to defer any amount
to be earned for the fiscal year ending September 30, 1993 shall be made on or
before August 31, 1993, provided that a deferral may be elected only with
respect to a bonus or other income 


<PAGE>   2


whose amount has not been ascertained or the services to which the compensation
relates have not been performed as of the Plan's adoption date. Deferral
elections shall be made annually in accordance with the procedures set forth in
Section 6. A separate deferral election shall be required for each fiscal year.

6.       Manner of Electing Deferral

         A Participant shall elect a deferral by giving written notice to the
Administrator in a form prescribed by the Administrator. The notice shall
include (a) the amount or percentage to be deferred; and (b) the compensation to
which the deferral relates.

7.       Investments/Participant Accounts

         The Company shall establish a rabbi trust, whose terms shall be a part
of this Plan, to hold all compensation deferred under the Plan and the earnings
thereon. The trust fund may be invested by the trustee, by another investment
manager appointed by the Administrator or by a combination of both, as
determined by the Administrator.

         For each Participant there shall be established a Participant Account
which shall be credited with the amounts deferred on behalf of that Participant
plus his share of trust earnings on the accumulated deferrals. Participant
Accounts shall be valued on each September 30, and on such other date or dates
as the Administrator may determine. All amounts credited to Participant Accounts
shall be fully vested at all times, except for the possible claims of the
Company's general creditors. Amounts shall not be subject to forfeiture on
account of any action by a Participant or by the Company, including termination
of employment.

8.       Payment of Deferred Amounts

         No distribution or withdrawal may be made from a Participant Account
except as provided in this Section 8 or Section 9. Payments from an Account
shall commence on the first of the month following a Participant's death,
disability, retirement or other termination of employment from the Company and
shall be made in 120 monthly installments. The first installment shall equal the
value of the Participant Account at such time multiplied by a fraction, the
numerator of which is one and the denominator of which is the total number of
monthly installments to be made (120). Subsequent installments shall equal the
value of the Participant Account as of the last valuation date preceding the
installment which is to be paid multiplied by a fraction, the numerator of which
is one and the denominator of which is the total number of remaining
installments. The Administrator, in its sole discretion, shall have the right to
accelerate any such payments or to make payment of the balance in a Participant
Account in a lump sum.

9.       Designation of Beneficiary

         A Participant may designate the beneficiary or beneficiaries to receive
any balance in the Participant's Account which may remain unpaid at the
Participant's death. Such designation shall be effective by filing a written
notification with the Administrator and may be changed from time to time by
similar action. If no such designation is made, the Participant's estate shall
be deemed the Participant's beneficiary. The Participant's Account shall be paid
in 120 monthly installments or, if the Participant has commenced to receive
benefits prior to death, the balance of the 120-month period; provided that the
Administrator, in its sole discretion, shall have the right to accelerate any
such payments or to make payment of the balance in a Participant Account in a
lump sum.

10.      Participant's Rights Unsecured

         The maintenance of individual Participant Accounts is for bookkeeping
purposes only. No Participant shall have any property rights in any particular
assets held under the rabbi trust or by the Company, whether or not held for the
purpose of funding the Company's obligations. The right of any Participant or
his beneficiary to receive benefits under this Plan shall be an unsecured claim
against the general assets of the Company.

11.      Change in Control

         In the event of a change in control, all Participants who have
terminated employment shall have their Participant Accounts paid out to them
immediately in a lump sum. Any Participants who have not terminated employment
prior to a change in control shall have their Participant Account paid out to
them in a lump sum payment immediately following this termination of employment.
For purposes of this section, the term "change in control" shall have the
meaning given it in the Company's 1993 long-term incentive plan.

12.      Statement of Account

         Statements will be sent to a Participant no less frequently than
annually as to the value of his Participant Account.

13.      Transferability

         The rights of a Participant under this Plan shall not be transferable
other than by will or the laws of descent and distribution and are exercisable
during the Participant's lifetime only by the Participant or by the
Participant's guardian or legal representative. A Participant's right to benefit
payments under the Plan are not subject in any manner to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or
garnishment by creditors of the Participant or the Participant's beneficiary.


                                       -3-

14.      Amendment

         This Plan may at any time or from time to time be amended, modified or
terminated by the Board of Directors of the Company. No amendment, modification
or termination shall, without the consent of a Participant, adversely affect
such Participant's accruals in his Participant Account.

15.      Taxes

         To the extent required by the law in effect at the time payments are
made, taxes required to be withheld by the federal or any state or local
government shall be withheld from the payments made hereunder.

16.      Claims Procedure

         If the Participant or the Participant's beneficiary (hereinafter
referred to as a "Claimant") is denied all or a portion of any expected benefit
under this Plan for any reason, he or she may file a claim with the
Administrator. The Administrator shall notify the Claimant within 60 days of
allowance or denial of the claim, unless the Claimant receives written notice
from the Administrator prior to the end of the sixty (60) day period stating
that special circumstances require an extension of time for decision. The notice
of the Administrator's decision shall be in writing, sent by mail to Claimant
last known address, and, if denial of the claim, must contain the following
information:

          (a)  the specific reason for the denial;

          (b)  specific reference to pertinent provisions of the Plan on which
               the denial is based; and

          (c)  If applicable, a description of any additional information or
               material necessary to perfect the claim, an explanation of why
               such information or material is necessary, and an explanation of
               the claims review procedure.

17.      Review Procedure

         A Claimant is entitled to request a review of any denial of his claim
by the Administrator. The request for review must be submitted in writing within
60 days of mailing of notice of the denial. Absent a request for review within
the 60-day period, the claim will be deemed to be conclusively denied. The
Claimant or his representatives shall be entitled to review all pertinent
documents, and to submit issues and comments orally and in writing.

                                       -4-

<PAGE>   5

         If the request for review by a Claimant concerns the interpretation and
application of the provisions of this Plan and the Company's obligations, then
the review shall be conducted by the entire Board of Directors. The Board shall
afford the Claimant a hearing and the opportunity to review all pertinent
documents and submit issues and comments orally and in writing and shall render
a review decision in writing, all within sixty (60) days after receipt of a
request for a review, provided that, in special circumstances (such as the
necessity of holding a hearing) the Board may extend the time for decision by
not more than sixty (60) days upon written notice to the Claimant. The Claimant
shall receive written notice of the board's review decision, together with
specific reasons for the decision and reference to the pertinent provisions of
this Agreement.

18.      Governing Law

         This Plan and any Participant elections hereunder shall be interpreted
and enforced in accordance with the laws of the State of Delaware.

19.      Effective Date

         The effective date of this Plan is the signature date specified below.

         IN WITNESS WHEREOF, the Company has caused its duly authorized officer
to execute this Plan document on its behalf this 8th day of September, 1993.
