3.  In the first quarter of fiscal 2000, the Company completed three
    acquisitions for cash. The aggregate purchase price of the acquisitions, net
    of cash acquired, (none of which individually or aggregated was significant)
    was approximately $91.9 million. There are no future purchase price
    adjustments due to earnout provisions from any of these three transactions.
    All three of these acquisitions have been accounted for as purchases. The
    results of these acquisitions were included as of the date they were
    acquired. The total goodwill and intangibles for the acquired companies was
    approximately $82.0 million and will be amortized over 20 to 30 years.
    Descriptions of the acquired companies are as follows:

    (a)  On October 7, 1999, the Company acquired Robbins Scientific Corporation
         ("Robbins"), a manufacturer of biomedical products used in certain
         types of high throughput screening, molecular biology, chemical
         synthesis and tissue typing. Robbins' line of products include
         microdispensers and automated dispensing machines with specialty
         pipette tips for robotic workstations, plastic plates, tubes, storage
         tools and hybridization incubators, gel loaders and water baths,
         organic synthesis systems, filtration blocks and covers, trays, and
         syringe dispensers. Robbins' revenues in 1999 were approximately $19.6
         million. Robbins is included in the Company's Labware and Life Sciences
         business segment.

    (b)  On October 13, 1999, the Company acquired Microm Laborgerate GmbH
         ("Microm"), a leading manufacturer of histology laboratory
         instrumentation headquartered in Walldorf, Germany. Microm's products
         include microtome and cryostat machines used in tissue sectioning, as
         well as automatic slide stainers, tissue processors, cover slippers and
         cassettes used in routine histology and cytology applications. Microm's
         sales in 1999 were approximately $20.7 million. Microm is included in
         the Company's Clinical and Industrial business segment.

    (c)  On December 13, 1999 the Company acquired Professional Positioners,
         Inc. ("Pro"), a manufacturer of orthodontic retainers and positioners.
         Pro's products range from functional orthopedic devices used at the
         beginning of orthodontic treatment to retainers and positioners which
         are used to hold teeth in the final occlusion after treatment. Pro's
         sales revenues in 1999 were approximately $5.4 million. Pro is included
         in the Company's Orthodontics business segment.

    Two acquisitions were completed for cash after the first fiscal quarter of
    2000 and will be accounted for as purchases. The aggregate purchase price
    was not significant either individually or aggregated. There are no future
    purchase price adjustments due to earnout provisions from either of these
    transactions. The results of these acquisitions will be included as of the
    date they were acquired. The total goodwill for the acquired companies is
    currently being assessed. Descriptions of the acquired companies are as
    follows:

    (a)  On February 1, 2000, the Company acquired the Versi-Dry(R) product line
         from National Packaging Services Corporation ("NPS") located in Green
         Bay, Wisconsin. The Versi-Dry(R) product is an absorbent pad used in
         research and industrial laboratories and is designed to absorb and
         contain chemicals and other spillage occurring in the laboratory. Sales
         revenues in 1999 were approximately $2.5 million. The Versi-Dry(R)
         product line will be included in the Labware and Life Sciences business
         segment.

    (b)  On February 4, 2000, the Company acquired Sun International ("Sun"), a
         leading supplier of consumables for high-pressure liquid chromatography
         (HPLC), gas chromatography (GC) and high throughput screening (HTS)
         applications. In addition to autosampler vials, inserts and closures,
         Sun recently introduced their PLATE+(TM) and MICROMAT(TM) product line
         for high throughput screening in the biotechnology and pharmaceutical
         markets. Sales revenues in 1999 were approximately $5.8 million. Sun
         will be included in the Labware and Life Sciences business segment.

4.  In June 1998, the Company recorded a restructuring charge of approximately
    $24 million (approximately $16.7 million after tax or $.16 per share on a
    diluted basis) for the rationalization of certain acquired companies,
    combination of certain duplicate production facilities, movement of certain
    customer service and marketing functions, and the exiting of several product
    lines. The restructuring charge was originally classified as components of
    cost of sales (approximately $6.4 million relating to the write-off of
    inventory discussed below), selling, general and administrative expenses
    (approximately $16.9 million) and income tax expense (approximately $0.7
    million). Upon reclassifying Nalge Process Technologies Group, Inc. ("NPT")
    to a discontinued operation in December 1998, approximately $0.3 million and
    $0.6 million were reclassified from cost of sales and selling, general and
    administrative expenses to discontinued operations.

(a) Amount represents severance and termination costs for approximately 165
    terminated employees (primarily sales and marketing personnel). As of
    December 31, 1999, 154 employees have been terminated as a result of the
    restructuring plan. Payments will continue to certain employees previously
    terminated under this restructuring plan. An adjustment of approximately
    $900 was made in the third quarter of fiscal 1999 to adjust the accrual
    primarily representing over accruals for anticipated costs associated with
    outplacement services, accrued fringe benefits, and severance associated
    with employees who were previously notified of termination and subsequently
    filled other Company positions. No additional employees will be terminated
    under this restructuring plan.
(b) Amount represents lease payments and shutdown costs on exited facilities.
(c) Amount represents write-offs of inventory and fixed assets associated with
    discontinued product lines.
(d) Amount represents a statutory tax relating to assets transferred from an
    exited sales facility in Switzerland.
(e) Amount represents goodwill associated with exited product lines at Sybron
    Laboratory Products Corporation ("SLP").
(f) Amount represents certain terminated contractual obligations primarily
    associated with Sybron Dental Specialties, Inc.

    The Company expects to make future cash payments of approximately $700 in
    the remainder of fiscal 2000 and approximately $1,100 in fiscal 2001 and
    beyond.

5.  For the three months ended December 31, 1998, the Company incurred
    approximately $2.7 million ($1.7 million after tax or $.02 per share on a
    diluted basis) of costs associated with the October 29, 1998 merger with
    Pinnacle Products of Wisconsin, Inc. ("Pinnacle") (the "Pinnacle Merger")
    and the integration of "A" Company Orthodontics (`"A" Company'), a
    subsidiary of LRS Acquisition Corp. ("LRS"), with SDS. LRS was merged with a
    subsidiary of the Company on April 9, 1998 (the "LRS Merger"). Both
    transactions were accounted for as poolings of interests. The costs
    associated with the Pinnacle Merger and the integration of "A" Company were
    primarily from Pinnacle Merger non-shareholder compensation (approximately
    $2.0 million), and costs related to miscellaneous expenses primarily related
    to completing the "A" Company integration including customer announcements,
    professional fees, and relocation expenses (approximately $0.7 million). The
    Company does not anticipate incurring any further merger, transaction and
    integration expenses associated with the LRS and Pinnacle Mergers.

6.   On March 31, 1999, the Company completed the sale of NPT. The results of
     NPT in the fiscal 1999 period are classified as discontinued operations. In
     addition, in the first quarter of fiscal 2000, the Company refunded
     approximately $2.6 million of previously accrued purchase price adjustments
     to the purchaser. The Company does not anticipate any additional
     adjustments to the purchase price.

      Over the past several years the Company has been pursuing a growth
strategy designed to increase sales and enhance operating margins. Elements of
that strategy include emphasis on acquisitions, product line extensions, new
product introductions, international growth and rationalization of existing
businesses and product lines.

      When we use the terms "we" or "our" in this report, we are referring to
Sybron International Corporation and its subsidiaries. Our fiscal year ends on
September 30 and, accordingly, all references to quarters refer to the Company's
fiscal quarters. The quarters ended December 31, 1998 and 1999, refer to the
Company's first fiscal quarters of 1999 and 2000, respectively.

      Our results for the three months ended December 31, 1998 include
approximately $2.7 million of charges relating to integration costs associated
with the merger with LRS Acquisition Corp. ("LRS") (the "LRS Merger"), the
parent of "A" Company, and transaction costs associated with the merger with
Pinnacle Products of Wisconsin, Inc. ("Pinnacle") (collectively, the "1999
Special Charges").

      Both our sales and operating income for the quarter ended December 31,
1999 grew over the corresponding prior year period. Net sales for the first
quarter of fiscal 2000 increased by 20.1% over the corresponding fiscal 1999
period. Operating income for the first quarter of fiscal 2000 increased by 29.9%
over the corresponding fiscal 1999 period. Excluding the 1999 Special Charges,
operating income for the first quarter of fiscal 2000 increased by 23.6% over
the corresponding fiscal 1999 period.

      Sales growth in the quarter was strong both domestically and
internationally. Domestic and international sales increased by 22.0% and by
15.9%, respectively, over the corresponding fiscal 1999 quarter. International
sales growth was negatively impacted by the strengthening of the U.S. dollar.
Without the negative currency effects, international sales growth would have
been 20.4% over the corresponding fiscal 1999 period.

      Sales growth for the quarter in our dental businesses was negatively
impacted by a backlog build-up in curing lights attributable to a vendor
component shortage as well as soft orthodontic sales. Although there was general
softness in our orthodontic sales, the problem was particularly acute in
Germany, our largest European market for orthodontics, where we suffered a
decline in business resulting from year-end reimbursement cuts by the government
to orthodontic practitioners. Sales growth in our laboratory business was
negatively impacted by a decline in sales in our laboratory equipment business.
Although we are taking steps to address these issues, there can be no assurance
that these conditions will not continue to have a negative impact on our
results.

      We continue to maintain an active program of developing and marketing new
products and product line extensions, as well as pursuing growth through
acquisitions. We completed three acquisitions in the first quarter of fiscal
2000. (See Note 3 to the Unaudited Consolidated Financial Statements.)

      Our results of operations include goodwill amortization, other
amortization, and depreciation. These non-cash charges totaled $20.8 million and
$15.8 million for the quarters ended December 31, 1999 and 1998, respectively.
Because our operating results reflect significant depreciation and amortization
expense largely associated with stepped-up assets, goodwill and other
intangibles from our acquisition program and the leveraged buyout in 1987 of a
company known at that time as Sybron Corporation (the "Acquisition"), we believe
our "Adjusted EBITDA" is a useful measure of our ability to internally fund our
liquidity requirements. "Adjusted EBITDA" (while not a measure under generally
accepted accounting principles ("GAAP"), and not a substitute for GAAP measured
earnings or cash flows or an indication of operating performance or a measure of
liquidity) represents, for any relevant period, net income from continuing
operations plus (i) interest expense, (ii) provision for income taxes, (iii) the
1999 Special Charges and (iv) depreciation and amortization, all determined on a
consolidated basis and


                                       13
<PAGE>   15

in accordance with GAAP. Our "Adjusted EBITDA" amounted to $89.3 million and
$71.6 million for the quarters ended December 31, 1999 and 1998, respectively.

      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 1998, we 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 were 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. These options were sold
or expired worthless in their respective quarters of fiscal 1999 at a net gain
of $1.1 million. In November 1999, we again decided to employ a series of
foreign currency options with a U.S. dollar notional amount of approximately
$47.6 million at a cost of approximately $1.2 million. These options are
designed to protect the Company from potential detrimental effects of currency
movements associated with the U.S. dollar verses the Euro, Danish krone and
Japanese yen in the second, third and fourth quarters of fiscal 2000 as compared
to the second, third and fourth quarters of fiscal 1999.

    Overall Company. Net sales for the first quarter of fiscal 2000, ended
December 31, 1999 increased by $49.9 million or 20.1% from the corresponding
fiscal 1999 quarter. Net sales at SLP increased by $48.5 million in the first
quarter of fiscal 2000, an increase of 31.0% from SLP's net sales in the
corresponding fiscal 1999 quarter. Net sales at SDS increased by $1.4 million in
the first quarter of fiscal 2000, an increase of 1.6% from SDS's net sales in
the corresponding fiscal 1999 quarter.

    Labware and Life Sciences. Increased net sales in the Labware and Life
Sciences segment resulted primarily from: (a) net sales of products of acquired
companies (approximately $19.2 million), (b) increased net sales of existing
products (approximately $6.0 million), (c) increased net sales of new products
(approximately $0.4 million) and (d) price increases (approximately $0.3
million). Increased net sales were partially offset by unfavorable foreign
currency fluctuations (approximately $0.6 million).

    Clinical and Industrial. Increased net sales in the Clinical and Industrial
segment resulted primarily from: (a) net sales of products of acquired companies
(approximately $8.1 million), (b) increased net sales of existing products
(approximately $2.7 million) and (c) price increases (approximately $1.4
million). Increased net sales were partially offset by unfavorable foreign
currency fluctuations (approximately $0.6 million).

    Diagnostics and Microbiology. Increased net sales in the Diagnostics and
Microbiology segment resulted primarily from: (a) net sales of products of
acquired companies net of discontinued products (approximately $10.3 million),
(b) increased net sales of existing products (approximately $3.5 million) and
(c) increased net sales of new products (approximately $0.4 million). Increased
net sales were partially offset by price decreases (approximately $0.4 million).

    Laboratory Equipment. Decreased net sales in the Laboratory Equipment
segment resulted primarily from decreased net sales of existing products
primarily related to the constant temperature business, ovens and incubators
(approximately $3.3 million). This business is expected to continue to undergo


                                       15
<PAGE>   17

pressure due to the large number of competing companies in the marketplace.
Decreased net sales were partially offset by: (a) net sales of products of
acquired companies (approximately $0.5 million), (b) increased net sales of new
products (approximately $0.4 million) and (c) price increases (approximately
$0.2 million).

    Professional Dental. Increased net sales in the Professional Dental segment
resulted primarily from increased net sales of new products (approximately $4.6
million). New products sales were hampered by a backlog build-up in a new curing
light attributable to a vendor component shortage. Increased net sales were
partially offset by: (a) decreased net sales of existing products (approximately
$0.9 million), (b) unfavorable foreign currency fluctuations (approximately $0.7
million) and (c) discontinued product lines (approximately $0.5 million).

    Orthodontics. Decreased net sales in the Orthodontics segment resulted
primarily from: (a) decreased net sales of existing products (approximately $1.8
million) primarily related to soft orthodontic sales in Germany where doctors
suffered some year end reimbursement cuts by the government and (b) unfavorable
foreign currency fluctuations (approximately $1.0 million). Although the Company
is taking steps to address the softness in orthodontic sales, there is no
assurance that these conditions will not continue to have a negative impact on
our results. Decreased net sales were partially offset by: (a) increased net
sales of new products (approximately $0.9 million) and (b) increased net sales
of products of acquired companies net of discontinued products (approximately
$0.5 million).

    Infection Control Products. Increased net sales in the Infection Control
Products segment resulted primarily from net sales of products of acquired
companies (approximately $1.0 million) partially offset by decreased net sales
of existing products due to dealer consolidations and product life cycle
maturities (approximately $0.7 million).

partially offset by decreased general and administrative expenses (approximately
$0.3 million).

    Laboratory Equipment. Decreased selling, general and administrative expenses
in the Laboratory Equipment segment resulted primarily from: (a) decreased
marketing expenses (approximately $0.4 million) and (b) decreased general and
administrative expenses (approximately $0.1 million). Decreased selling, general
and administrative expenses were partially offset by: (a) increased selling,
general and administrative expenses as a result of acquired businesses
(approximately $0.1 million) and (b) increased amortization of intangibles
primarily as a result of acquisitions (approximately $0.1 million).

    Professional Dental. Decreased selling, general and administrative expenses
in the Professional Dental segment resulted primarily from: (a) the
non-recurring 1999 Special Charges (approximately $2.0 million), (b) decreased
selling and marketing expenses (approximately $0.6 million), (c) reduced general
and administrative expenses (approximately $0.3 million) and (d) decreased
research and development expenses (approximately ($0.2 million).

expenses in the Infection Control Products segment resulted primarily from: (a)
increased selling, general and administrative expenses as a result of acquired
companies (approximately $0.1 million), (b) amortization of intangibles
primarily from acquired businesses (approximately $0.1 million) and (c)
increased general and administrative expenses (approximately $0.1 million).
Increased selling, general and administrative expenses were partially offset by
decreased selling and marketing expenses (approximately $0.2 million).

    Corporate Office. Increased selling, general and administrative expenses at
the corporate office resulted primarily from: (a) an increase in legal expense
and professional fees (approximately $0.6 million).

</TABLE>

    As a result of the foregoing, operating income in the first quarter of
fiscal 2000 increased by 29.9% or $15.8 million over operating income in the
corresponding quarter of fiscal 1999.

    INTEREST EXPENSE.

    Interest expense was $17.9 million in the first quarter of fiscal 2000, an
increase of $3.8 million from the corresponding fiscal 1999 quarter. The
increase resulted from a higher average debt balance in 2000, resulting
primarily from funding acquisitions (partially offset by the application of
proceeds from the sale of Nalge Process Technologies Group, Inc. ("NPT") in
March 1999) and an increase in average interest rates primarily due from the
addition of a Term B Loan in July 1999.

    INCOME TAXES.

    Taxes on income from continuing operations in the first quarter of fiscal
2000 were $20.1 million, an increase of $4.5 million from the corresponding 1999
quarter. The increase resulted primarily from increased taxable earnings.

    INCOME FROM CONTINUING OPERATIONS.

    As a result of the foregoing we had net income from continuing operations of
$30.4 million in the first quarter of fiscal 2000, as compared to $23.3 million
in the corresponding 1999 period.

    DISCONTINUED OPERATIONS.

    Income from discontinued operations was $0.5 million in the first quarter of
fiscal 1999. The 1999 discontinued operations resulted from the operating
results of NPT. On March 31, 1999 Sybron completed the sale of NPT to Norton
Performance Plastics Corporation, a subsidiary of Saint-Gobain-France. Net
proceeds from the sale, net of $1.9 million of selling expenses and a reduction
to the original purchase price of approximately $2.6 million, amounted to $83.2
million. The proceeds of the sale net of tax and expenses were used to repay
approximately $67.9 million of debt under the Company's credit facilities.

    NET INCOME.

    As a result of the foregoing, we had net income of $30.4 million in the
first quarter of fiscal 2000, as compared to net income of $23.9 million in the
corresponding 1999 period.

      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 $5.0 million in the first quarter of fiscal 2000 due to
additional depreciation and amortization from the step-up of assets, goodwill
and intangibles recorded from the various acquisitions as well as routine
operating capital expenditures.

LIQUIDITY AND CAPITAL RESOURCES

         As a result of the acquisition of Sybron's predecessor in 1987 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. Goodwill
and other intangible assets increased by approximately $84.2 million in the
first quarter of fiscal 2000, primarily as a result of continued acquisition
activity. We believe, therefore, that Adjusted EBITDA represents the more
appropriate measure of our ability to internally fund our capital requirements.

    Our capital requirements arise principally from indebtedness incurred in
connection with the permanent financing for the 1987 acquisition and our
subsequent refinancings, our obligation to pay rent under the Sale/Leaseback
facility (as defined later herein), 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 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.

    The preceding statement about 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 or use of stock for acquisitions, the cost of 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
acquisitions. See "Cautionary Factors" below.

    Approximately $21.5 million of cash was generated from operating activities
in the first quarter of fiscal 2000, an increase of $3.0 million or 16.1%, from
the corresponding 1999 period. Increased cash flow from operating activities
resulted primarily from an increase in Adjusted EBITDA (approximately $17.7
million), a decrease in taxes paid (approximately $6.1 million) partially offset
by increases in



                                       21
<PAGE>   23


other net assets (approximately $18.3 million) and an increase in interest paid
(approximately $2.5 million). Approximately $100.2 million of cash was used in
investing activities in the first quarter of fiscal 2000, an increase of $40.3
million, or 67.2%, from the corresponding 1999 period. Increased investing
activities resulted primarily from an increase in acquisitions (approximately
$38.6 million), increased capital expenditures (approximately $2.0 million)
partially offset by an increase in the proceeds from sales of property plant and
equipment (approximately $0.3 million). Approximately $84.0 million of cash was
provided from financing activities, primarily from the Company's existing Credit
Facilities (approximately $90.6 million), partially offset by a refund of
collateral under a securities loan agreement (approximately $2.8 million), and
repayments of other financing sources (approximately $3.8 million). With respect
to the 1998 restructuring charge of approximately $24.0 million, of which
approximately $11.7 million represents cash expenditures, as of December 31,
1999, we have made cash payments of approximately $9.9 million. The Company
expects to make future cash payments of approximately $0.7 million in fiscal
2000 and approximately $1.1 million in fiscal 2001 and beyond.

    On July 31, 1995, we entered into a credit agreement (as amended to date,
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 "Tranche A Term Loan Facility"), and a revolving credit
facility of $250 million (the "Revolving Credit Facility"). On the same day, we
borrowed $300 million under the Tranche A 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 Tranche A 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 Eurodollar Rate and Tranche A 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 Tranche A 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 provided us with the ability to use proceeds from the
issuance of additional unsecured, subordinated 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. On July 29, 1999, we entered into the Third Amended and Restated Credit
Agreement (the "Third Amendment") and borrowed an additional $300 million under
a new term loan facility (the "Tranche B Term Loan Facility"). On July 29, 1999,
we used the $300 million of proceeds

                                       22
<PAGE>   24


from the Tranche B Term Loan Facility (after a reduction for fees of
approximately $1.6 million) to repay $298.4 million of outstanding amounts under
the Revolving Credit Facility.

    Payment of principal and interest with respect to the credit facilities and
the Sale/Leaseback (as defined later herein) are anticipated to be our largest
use of operating funds in the future. The Tranche A Term Loan Facility and
Revolving Credit Facility 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 "Tranche
A ABR") or (b) the adjusted interbank offered rate for eurodollar deposits
("Eurodollar Rate") plus 1/2% to 7/8% (the "Tranche A Eurodollar Rate Margin")
depending upon the ratio of our total debt to Consolidated Adjusted Operating
Profit (as defined in the Third Amendment), or (c) with respect to certain
advances under Revolving Credit Facility, the rate set by the competitive bid
process among the parties to the Revolving Credit Facility ("CAF"). The Tranche
B Term Loan Facility provides 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 plus 1% to 1 1/4%, (ii) the federal funds
rate plus of 1 1/2% to 1 3/4%, and (iii) the base CD rate plus 2% to 2 1/4%,
depending upon the ratio of our total debt to Consolidated Adjusted Operating
Profit or (b) the Eurodollar Rate plus 2% to 2 1/4% depending upon the ratio of
our total debt to Consolidated Adjusted Operating Profit. The average interest
rate on the Tranche A Term Loan Facility (inclusive of the swap agreements
described below) in the first quarter of fiscal 2000 was 6.3%. The average
interest rate on the Tranche B Term Loan Facility in the first quarter of fiscal
2000 was 7.7%. The average interest rate on the Revolving Credit Facility in the
first quarter of fiscal 2000 was 6.5%.

    As a result of the terms of our credit facilities, we are sensitive to a
rise in interest rates. A rise in interest rates would result in increased
interest expense on our outstanding debt. In order to reduce our sensitivity to
interest rate increases, from time to time we enter into interest rate swap
agreements. As of December 31, 1999, the Company has eight interest rate swaps
outstanding aggregating a notional amount of $383.5 million. Under the terms of
the swap agreements, the Company is required to pay a fixed rate amount equal to
the swap agreement rate listed below. In exchange for the payment of the fixed
rate amount, the Company receives a floating rate amount equal to the
three-month LIBOR rate in effect on the date of the swap agreements and the
subsequent reset dates. For each of the swap agreements the rate resets on each
quarterly anniversary of the swap agreement date until the swap expiration date.
The net interest rate paid by the Company is approximately equal to the sum of
the swap agreement rate plus the applicable Eurodollar Rate Margin. In the first
quarter of fiscal 2000, the Tranche A and Revolver Eurodollar Rate Margins were
 .75%. The Tranche B Eurodollar Margin, which became applicable on July 29, 1999,
was 2.0%. The swap agreement rates and durations as of December 31, 1999 are as
follows:

    Also as part of the permanent financing for the acquisition of Sybron's
predecessor in 1987, 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 1999, the annual obligation under the
Sale/Leaseback increased from $3.3 million to $3.6 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, 2004.

    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 would have to raise additional capital.

    The Revolving Credit Facility provides up to $600 million in available
credit. At December 31, 1999, there was approximately $224.6 million of
available credit under the Revolving Credit Facility. Under the Tranche A 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 fiscal 1997, $35.0
million due in fiscal 1998 and, during the first half of fiscal 1999, $17.5
million of the $36.25 million due in fiscal 1999. On March 31, 1999, as a result
of the sale of NPT, the Company received approximately $87.7 million
(approximately $86.0 million net of fees and expenses). The net proceeds were
subsequently reduced in October 1999 by approximately $2.8 million relating to a
reduction in the purchase price of approximately $2.6 million and additional
fees of $0.2 million. Net proceeds of the sale, after a reduction for estimated
applicable income taxes, were required to be used to repay amounts owed by the
Company under the Tranche A Term Loan Facility. On March 31, 1999, the Company
paid principal of approximately $67.9 million due under the Tranche A Term Loan
Facility. The following table shows how the payments were applied, and the
resulting revised schedule of principal payments under the Tranche A Term Loan
Facility.

    In addition, under the terms of the Tranche B Term Loan Facility, the
Company will be required to repay principal in consecutive quarterly
installments beginning on January 31, 2000 as follows: $0.75 million due in
fiscal 2000, $1.0 million due in fiscal 2001, $1.0 million due in fiscal 2002,
$120.25 million due in fiscal 2003 and $177 million due in fiscal 2004, with the
final payment due on July 31, 2004. To secure the repayment of borrowings under
the Credit Agreement, the Company has pledged to Chase, as collateral agent for
the lenders, all of the capital stock of the Company's principal domestic

                                       24

subsidiaries and 65% of the capital stock of its principal foreign subsidiaries
(excluding capital stock not owned by the Company directly or indirectly, and
also excluding certain immaterial subsidiaries), and certain intra-company
promissory notes issued in connection with the acquisition of Nunc.

    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 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

         We did not experience any significant malfunctions or errors in our
information or non-information technology systems when the date changed from
1999 to 2000, and we have not experienced any significant problems with our
suppliers' or customers' ability to function as a result of the date change.
Because it is possible that the full impact of the date change has not been
fully recognized, we will continue to monitor our Y2K situation, particularly
through additional key dates such as February 29, 2000. We believe, however,
that any potential problems are likely to be minor, short-term, and correctable.

         From the beginning of fiscal 1998 through the first quarter of fiscal
2000, the Company incurred approximately $3.0 million in capital costs and
approximately $1.5 million in expenses for Y2K readiness matters. The primary
components of these costs were external consulting and hardware and software
upgrades. We did not separately track internal costs (primarily payroll costs of
employees) of our initiative.

EUROPEAN ECONOMIC MONETARY UNIT

         On January 1, 1999, eleven of the European Union countries (including
four countries in which we have operations) adopted the Euro as their single
currency. At that time, a fixed exchange rate was established between the Euro
and the individual countries' existing currencies (the "legacy currencies"). The
Euro trades on currency exchanges and is 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.

         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.
Forward-looking statements may also be made by us 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 herein 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 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; and risks associated with the economic downturns
         in other countries.

-        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 acquisitions.

-        Our reliance on major independent distributors for a substantial
         portion of our sales subjects our sales performance to volatility in
         demand if distributor inventories get out of balance with end user
         demand. This can happen when distributors merge or consolidate, or when
         inventories are not managed to end-user demand.

-        Factors affecting our ability to profitably distribute and sell our
         products, including any changes in our business relationships with our
         principal distributors, primarily in the laboratory segment,
         competitive factors such as the entrance of additional competitors into
         our markets, pricing and technological competition, and risks
         associated with the development and marketing of new products in order
         to remain competitive by keeping pace with advancing dental,
         orthodontic and laboratory technologies.

-        With respect to Erie, factors affecting its Erie Electroverre S.A.
         subsidiary's ability to manufacture the glass used by Erie's worldwide
         manufacturing operations, including delays encountered in connection
         with the periodic rebuild of the sheet glass furnace and furnace
         malfunctions at a time when inventory levels are not sufficient to
         sustain Erie's flat glass operations.

                                       26
<PAGE>   28

-        Factors affecting our ability to hire and retain competent employees,
         including unionization of our non-union employees and changes in
         relationships with our unionized employees.

-        The risk of strikes or other labor disputes at those locations which
         are unionized which could affect our operations.

-        Factors affecting our ability to continue manufacturing and selling
         those of our products that are subject to regulation by the United
         States Food and Drug Administration or other domestic or foreign
         governments or agencies, including the promulgation of stricter laws or
         regulations, reclassification of our products into categories subject
         to more stringent requirements, or the withdrawal of the approval
         needed to sell one or more of our products.

-        Factors affecting the economy generally, including a rise in interest
         rates, the financial and business conditions of our customers and the
         demand for customers' products and services that utilize Company
         products.

-        Factors relating to the impact of changing public and private health
         care budgets which could affect demand for or pricing of our products.

-        Factors affecting our financial performance or condition, including tax
         legislation, unanticipated restrictions on our ability to transfer
         funds from our subsidiaries and changes in applicable accounting
         principles or environmental laws and regulations.

-        The cost and other effects of claims involving our products and other
         legal and administrative proceedings, including the expense of
         investigating, litigating and settling any claims.

-        Factors affecting our ability to produce products on a competitive
         basis, including the availability of raw materials at reasonable
         prices.

-        Unanticipated technological developments that result in competitive
         disadvantages and create the potential for impairment of our existing
         assets.

-        Factors affecting our operations in European countries related to the
         conversion from local legacy currencies to the Euro.

-        Other business and investment considerations that may be disclosed from
         time to time in our Securities and Exchange Commission filings or in
         other publicly available written documents.

    We undertake no obligation to publicly update or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise.

ITEM 3. 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 Euro, Danish Krone 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. In November 1999 we entered into nine
foreign currency options to hedge our exposure to each of the aforementioned
currencies.

    In 2000, we expect our exposure from our primary foreign currencies to
approximate the following:

      Danish Krone (DKK)                                          87,400 DKK                  12,485

</TABLE>

    As a result of these anticipated exposures, we entered into a series of
options expiring at the end of the second, third and fourth quarters of 2000 to
protect ourselves from possible detrimental effects of foreign currency
fluctuations. 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 purchased put options on the
foreign currencies at amounts approximately equal to our quarterly exposure. The
EUR and DKK options expire on a quarterly basis, at an exchange rate
approximately equal to the spot exchange rate at the date of purchase for each
of the respective currencies. The JPY options expire on a quarterly basis at an
exchange rate approximately equal to the prior year's respective quarters actual
exchange rate. In November 1999, 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 Eurodollar Rate. Interest
rate risk management is accomplished by the use of swaps to create fixed
interest rate debt by resetting Eurodollar Rate loans concurrently with the
rates applying to the swap agreements. At December 31, 1999 we had floating rate
debt of approximately $943.2 million of which a total of $383.5 million was
swapped to fixed rates. The net interest rate paid by the Company is
approximately equal to the sum of the swap agreement rate plus the applicable
Eurodollar Rate Margin. In the first quarter of fiscal 2000, the Tranche A and
Revolver Eurodollar Rate Margins were .75%. The Tranche B Eurodollar Margin,
which became applicable on July 29, 1999, was 2.0%. The swap agreement rates and
durations as of September 30, 1999 are as follows:

    In addition to the aforementioned swaps, on September 29, 1999, the Company
entered into a repurchase agreement in which we purchased a United States
Treasury Bond ("Treasury") with a par value of $50 million, an interest rate of
6.15% and a maturity date of August 15, 2029. Concurrent with the purchase of
the Treasury, the Company lent the security to an unrelated third party for a
period of 23 years. In exchange for the loaned Treasury, the Company has
received collateral equal to the market value of the Treasury on the date of the
loan, and adjusted on a weekly basis. For a period of five years the Company is
obligated to pay a rebate on the loaned collateral at an annual fixed rate of
6.478% and is entitled to receive a fee for the loan of the security at a
floating rate equal to LIBOR minus .75%. Thereafter, the Company is required to
pay the unrelated third party a collateral fee equal to the one-week general
collateral rate of interest (as determined weekly in good faith by the unrelated
third party, provided that such rate shall not exceed the federal funds rate in
effect as of the day of determination plus .25%).

    The model below quantifies the Company's sensitivity to interest rate
movements as determined by the Eurodollar Rate and the effect of the interest
rate swaps which reduce that risk. The model assumes a) a base Eurodollar Rate
of 6.00% (the "Eurodollar Base Rate") which approximates the December 31, 1999
three month Eurodollar Rate, b) the Company's floating rate debt is equal to
it's December 31, 1999 floating rate debt balance of $943.8 million, c) the
Company pays interest on floating rate debt equal to the Eurodollar Rate + 75
basis points, d) the Company has interest rate swaps (including the repurchase
agreement) with a notional amount of $433.5 million (equal to the notional
amount of the Company's interest rate swaps at December 31, 1999), and e) the
Eurodollar Rate varies by 10% of the Base Rate.
