3.    Earnings per Share (continued)

      The computation of diluted earnings per share for each period excludes the
effect of assuming the exercise of certain outstanding stock options because the
effect would be antidilutive. As of July 3, 1999, there were 2,192,000 of such
options outstanding, with exercise prices ranging from $11.63 to $17.20 per
share.

5.    Accrued Acquisition Expenses

      The Company has undertaken restructuring activities at certain acquired
businesses. The Company's restructuring activities, which were accounted for in
accordance with Emerging Issues Task Force Pronouncement (EITF) 95-3, primarily
have included reductions in staffing levels and the abandonment of excess
facilities. In connection with these restructuring activities, as part of the
cost of acquisitions, the Company established reserves, primarily for severance
and excess facilities. In accordance with EITF 95-3, the Company finalizes its
restructuring plans no later than one year from the respective dates of the
acquisitions. As of January 2, 1999, the remaining reserve for these
restructuring activities totaled $331,000, and related to the abandonment of
excess facilities. During the first six months of 1999, the Company expended
$14,000 of the established reserve. As of July 3, 1999, the remaining reserve
for restructuring activities at acquired businesses totaled $298,000, as
adjusted for the impact of foreign currency translation, and is included in
other accrued expenses in the accompanying balance sheet.

6.     Restructuring Costs

      During 1998, the Company recorded restructuring costs, which were
accounted for in accordance with EITF 94-3, for severance for 85 employees. As
of January 2, 1999, the Company had terminated 49 employees and had $1,634,000
accrued for severance. During the first six months of 1999, the Company
terminated 31 employees and had expended $788,000 of the established reserve for
severance. As of July 3, 1999, the remaining reserve for severance totaled
$679,000, as adjusted for the impact of foreign currency translation, and is
included in other accrued expenses in the accompanying balance sheet.

7.     Cash Management Arrangement

      Effective June 1, 1999, the Company and Thermo Electron Corporation
commenced use of a new domestic cash management arrangement. Under the new
arrangement, amounts advanced to Thermo Electron by the Company for domestic
cash management purposes bear interest at the 30-day Dealer Commercial Paper
Rate plus 50 basis points, set at the beginning of each month. Thermo Electron
is contractually required to maintain cash, cash equivalents, and/or immediately
available bank lines of credit equal to at least 50% of all funds invested under
this cash management arrangement by all Thermo Electron subsidiaries other than
wholly owned subsidiaries. The Company has the contractual right to withdraw its
funds invested in the cash management arrangement upon 30 days' prior notice.
Amounts invested in this arrangement are included in "advance to affiliate" in
the accompanying balance sheet.

Item 2 - Management's Discussion and Analysis of Financial Condition and Results of Operations

      Forward-looking statements, within the meaning of Section 21E of the
Securities Exchange Act of 1934, are made throughout this Management's
Discussion and Analysis of Financial Condition and Results of Operations. For
this purpose, any statements contained herein that are not statements of
historical fact may be deemed to be forward-looking statements. Without limiting
the foregoing, the words "believes," "anticipates," "plans," "expects," "seeks,"
"estimates," and similar expressions are intended to identify forward-looking
statements. There are a number of important factors that could cause the results
of the Company to differ materially from those indicated by such forward-looking
statements, including those detailed under the heading "Forward-looking
Statements" in Exhibit 13 to the Company's Annual Report on Form 10-K for the
year ended January 2, 1999, filed with the Securities and Exchange Commission.

Overview

      The Company's businesses are reported in two segments: Analytical
Instruments and Scientific Equipment. The Company's Analytical Instruments
segment develops, manufactures, sells, and services mass spectrometers, liquid
chromatographs, and gas chromatographs used in the quantitative and qualitative
analysis of chemical compounds at ultratrace levels of detection. The Company's
Analytical Instruments segment also supplies consumables for the chromatography
industry. The Company's Scientific Equipment segment develops, manufactures,
sells, and services scientific equipment for the preparation and preservation of
chemical samples. The Company's products are used primarily by pharmaceutical
companies for drug research, testing, and quality control; by biotechnology
researchers to study proteins and other biological samples to gain knowledge
about diseases and possible treatments; by environmental laboratories for
testing water, air, and soil samples for compliance with environmental
regulations; by chemical companies for research and quality control; by
manufacturers for testing in certain industrial applications, such as the
manufacture of silicon chips, and for quality control; by food and beverage
companies for quality control and to test for product contamination; and in
forensic applications.

      The Company sells its products worldwide. Although the Company seeks to
charge its customers in the same currency as its operating costs, the Company's
financial performance and competitive position can be affected by currency
exchange rate fluctuations. Where appropriate, the Company uses forward
contracts to reduce its exposure to currency fluctuations.

Results of Operations

Second Quarter 1999 Compared With Second Quarter 1998

      Revenues increased 10% to $107.9 million in the second quarter of 1999
from $98.1 million in the second quarter of 1998. Revenues from the Analytical
Instruments segment increased $7.1 million, or 11%, to $73.8 million in 1999
from $66.7 million in 1998. The increase resulted from an increase in revenues
in North America due to the introduction of new products at the Pittsburgh
Conference in March 1999 and an increase in revenues to customers in Asia due to
the improved economic conditions there, compared with the second quarter of
1998. The increases were

<PAGE>

Second Quarter 1999 Compared With Second Quarter 1998 (continued)

offset in part by a decrease in revenues of $0.7 million due to the unfavorable
effects of currency translation as a result of the strengthening in value of the
U.S. dollar relative to foreign currencies in countries in which the Company
operates. Revenues from the Scientific Equipment segment increased to $34.0
million in 1999 from $31.4 million in 1998, primarily due to an increase in
revenues in North America and Asia across all product lines.

      The gross profit margin decreased to 48% in the second quarter of 1999
from 49% in the second quarter of 1998, primarily due to a shift in the product
mix at the Analytical Instruments segment.

      Selling, general, and administrative expenses as a percentage of revenues
remained unchanged at 25% in the second quarter of 1999 and 1998. Selling,
general, and administrative expenses increased to $26.6 million in 1999 from
$25.0 million in 1998, primarily due to higher selling and marketing expenses in
both of the Company's segments.

      Research and development expenses decreased to $7.5 million in the second
quarter of 1999 from $8.1 million in the second quarter of 1998, primarily due
to lower spending in the Analytical Instruments segment as a result of the
completed development of certain new products.

      In the second quarter of 1998, the Company's Analytical Instruments
segment recorded a gain of $0.3 million, primarily relating to the sale of real
estate in California.

      Interest income was relatively unchanged at $1.6 million in the second
quarter of 1999, compared with $1.5 million in the second quarter of 1998.
Interest expense decreased to $1.3 million in 1999 from $2.0 million in 1998,
primarily due to the conversion and repurchase of a portion of the Company's 5%
subordinated convertible debentures.

      The effective tax rate was 42% in the second quarter of 1999 and 1998. The
effective tax rate exceeded the statutory federal income tax rate primarily due
to the effect of state income taxes, foreign tax rate and tax law differentials,
and nondeductible amortization of cost in excess of net assets of acquired
companies.

First Six Months 1999 Compared With First Six Months 1998

      Revenues increased to $213.5 million in the first six months of 1999 from
$206.2 million in the first six months of 1998. Revenues from the Analytical
Instruments segment increased $5.8 million to $147.7 million in 1999 from $141.9
million in 1998. The increase was primarily due to an increase in revenues to
customers in Asia due to the improved economic conditions there and, to a lesser
extent, an increase in revenues of $1.4 million due to the favorable effects of
currency translation as a result of the weakening of the U.S. dollar relative to
foreign currencies in countries in which the Company operates, primarily the
Japanese yen. The increases were offset in part by a decline in revenues from
customers in Brazil due to the unstable economic conditions there and, to a
lesser extent, lower demand for the Company's Fourier transform mass
spectrometers. Revenues from the Scientific Equipment segment increased to $65.8
million in 1999 from $64.4 million in 1998, primarily due to an increase in
revenues in North America in one of the Company's product lines, offset in part
by a decline in revenues from customers in Europe as a result of heightened
competition in one of the Company's product lines.

      The gross profit margin decreased to 48% in the first six months of 1999
from 49% in the first six months of 1998, primarily due to a shift in the
product mix at the Analytical Instruments segment.

      Selling, general, and administrative expenses as a percentage of revenues
remained unchanged at 25% in the first six months of 1999 and 1998. Selling,
general, and administrative expenses increased to $53.1 million in 1999 from
$51.0 million in 1998, primarily due to higher selling and marketing expenses in
both of the Company's segments.

First Six Months 1999 Compared With First Six Months 1998 (continued)

      Research and development expenses decreased to $15.0 million in the first
six months of 1999 from $16.0 million in the first six months of 1998, primarily
due to lower spending in the Analytical Instruments segment as a result of the
completed development of certain new products.

      In the first six months of 1999 and 1998, the Company's Analytical
Instruments segment recorded gains of $1.6 million and $1.0 million,
respectively, primarily relating to the sale of real estate in California.

      Interest income increased to $3.2 million in the first six months of 1999
from $2.9 million in the first six months of 1998, primarily due to higher
invested cash balances. Interest expense decreased to $2.6 million in 1999 from
$3.4 million in 1998, primarily due to the conversion and repurchase of a
portion of the Company's 5% subordinated convertible debentures.

      The effective tax rate was 42% in the first six months of 1999 and 1998.
The effective tax rate exceeded the statutory federal income tax rate primarily
due to the effect of state income taxes, foreign tax rate and tax law
differentials, and nondeductible amortization of cost in excess of net assets of
acquired companies.

Liquidity and Capital Resources

      Consolidated working capital was $214.6 million at July 3, 1999, compared
with $200.0 million at January 2, 1999. Included in working capital are cash and
cash equivalents of $46.9 million at July 3, 1999, compared with $132.4 million
at January 2, 1999. In addition, as of July 3, 1999, the Company had $98.9
million invested in an advance to affiliate. Prior to the use of a new domestic
cash management arrangement between the Company and Thermo Electron Corporation
(Note 7), which became effective June 1, 1999, amounts invested with Thermo
Electron were included in cash and cash equivalents. At July 3, 1999, $40.5
million of the Company's cash and cash equivalents was held by its foreign
subsidiaries. While this cash can be used outside of the United States,
including for acquisitions, repatriation of this cash into the United States
would be subject to foreign withholding taxes and could also be subject to a
U.S. tax.

      Cash provided by operating activities was $28.7 million in the first six
months of 1999. A decrease in accounts receivable provided cash of $12.4
million, primarily due to lower revenues in the second quarter of 1999, compared
with the fourth quarter of 1998. Cash of $4.7 million was used to reduce other
current liabilities, primarily due to a reduction in accrued payroll and related
benefits and customer deposits. Cash of $3.5 million was used to fund a decrease
in accounts payable, primarily due to the timing of payments.

      During the first six months of 1999, the Company's primary investing
activities, excluding advance to affiliate activity (Note 7), included the
purchase of property, plant, and equipment. The Company used cash of $2.3
million for purchases of property, plant, and equipment. In addition, the
Company received $1.7 million in proceeds from the sale of property, plant, and
equipment, primarily relating to the sale of real estate in California. During
the remainder of 1999, the Company plans to make capital expenditures of
approximately $5.0 million.

      The Company's financing activities used $12.0 million of cash in the first
six months of 1999. The Company used $5.1 million of cash to purchase Company
common stock and subordinated convertible debentures pursuant to an
authorization by the Company's Board of Directors. As of July 3, 1999, the
Company had a remaining authorization to purchase $2.5 million of its own
securities, through September 25, 1999, in the open market, or in negotiated
transactions. Such purchases are funded from working capital. During the first
six months of 1999, the Company used cash of $7.2 million for the repayment of
short- and long-term obligations.

      Although the Company expects to have positive cash flow from its existing
operations, the Company anticipates it will require significant amounts of cash
to pursue the acquisition of complementary businesses. The Company expects that
it will finance acquisitions through a combination of internal funds, and/or
short-term borrowings from Thermo Instrument Systems Inc. or Thermo Electron,
although there is no agreement with these companies to ensure that funds will be
available on acceptable terms or at all. The Company believes that its existing
resources are sufficient to meet the capital requirements of its existing
businesses for the foreseeable future.

Year 2000

      The following information constitutes a "Year 2000 Readiness Disclosure"
under the Year 2000 Information and Readiness Disclosure Act. The Company
continues to assess the potential impact of the year 2000 date recognition issue
on the Company's internal business systems, products, and operations. The
Company's year 2000 initiatives include (i) testing and upgrading significant
information technology systems and facilities; (ii) testing and developing
upgrades, if necessary, for the Company's current products; (iii) assessing the
year 2000 readiness of key suppliers and vendors; and (iv) developing a
contingency plan.

The Company's State of Readiness

      The Company has implemented a compliance program to ensure that its
critical information technology systems and non-information technology systems
will be ready for the year 2000. The first phase of the program, testing and
evaluating the Company's critical information technology systems and
non-information technology systems for year 2000 compliance, has largely been
completed. During phase one, the Company tested and evaluated its significant
computer systems, software applications, and related equipment for year 2000
compliance. The Company also evaluated the potential year 2000 impact on its
critical non-information technology systems, which efforts included testing the
year 2000 readiness of its manufacturing, utility, and telecommunications
systems at its critical facilities. The Company is currently in phase two of its
program, during which any noncompliant systems or non-information technology
systems that were identified during phase one are prioritized and remediated.
Based on its evaluations of its critical non-information technology systems, the
Company does not believe any material upgrades or modifications are required.
The Company is currently upgrading or replacing its material noncompliant
information technology systems, and this process was approximately 80% complete
as of July 3, 1999. In many cases, such upgrades or replacements are being made
in the ordinary course of business, without accelerating previously scheduled
upgrades or replacements. The Company expects that all of its material
information technology systems and critical non-information technology systems
will be year 2000 compliant by September 1999.

      The Company has also implemented a compliance program to test and evaluate
the year 2000 readiness of the material products that it currently manufactures
and sells. The Company believes that all of such material products are year 2000
compliant. However, as many of the Company's products are complex, interact with
or incorporate third-party products, and operate on computer systems that are
not under the Company's control, there can be no assurance that the Company has
identified all of the year 2000 problems with its current products. The Company
believes that certain of its older products, which it no longer manufactures or
sells, will not be year 2000 compliant.

      The Company is in the process of identifying and assessing the year 2000
readiness of key suppliers and vendors that are believed to be significant to
the Company's business operations. As part of this effort, the Company has
developed and has distributed questionnaires relating to year 2000 compliance to
its significant suppliers and vendors. To date, no significant supplier or
vendor has indicated that it believes its business operations will be materially
disrupted by the year 2000 issue. The Company has started to follow-up and
monitor the year 2000 compliance progress of significant suppliers and vendors
that indicate that they are not year 2000 compliant or that do not respond to
the Company's questionnaires. The Company has completed the majority of its
assessment of third-party risk, and expects to be substantially completed by
September 1999.

Contingency Plan

      The Company is developing a contingency plan that will allow its primary
business operations to continue despite disruptions due to year 2000 issues.
This plan may include identifying and securing other suppliers, increasing
inventories, and modifying production facilities and schedules. As the Company
continues to evaluate the year 2000 readiness of its business systems and
facilities, products, and significant suppliers and vendors, it will modify and
adjust its contingency plan as may be required. The Company expects to complete
its contingency plan by October 1999.

Year 2000 (continued)

Estimated Costs to Address the Company's Year 2000 Issues

      To date, costs incurred in connection with the year 2000 issue have not
been material. The Company does not expect total year 2000 remediation costs to
be material, but there can be no assurance that the Company will not encounter
unexpected costs or delays in achieving year 2000 compliance. Year 2000 costs
were funded from working capital. All internal costs and related external costs,
other than capital additions, related to year 2000 remediation have been and
will continue to be expensed as incurred. The Company does not track internal
costs incurred for its year 2000 compliance project. Such costs are principally
the related payroll costs for its information systems group.

Reasonably Likely Worst Case Scenario

      At this point in time, the Company is not able to determine the most
reasonably likely worst case scenario to result from the year 2000 issue. One
possible worst case scenario would be that certain of the Company's significant
suppliers or vendors experience business disruptions due to the year 2000 issue
and are unable to provide materials and services to the Company on time. The
Company's operations could be delayed or temporarily shut down, and it could be
unable to meet its obligations to customers in a timely fashion. The Company's
business, operations, and financial condition could be adversely affected in
amounts that cannot be reasonably estimated at this time. If the Company
believes that any of its key suppliers or vendors may not be year 2000 ready, it
will seek to identify and secure other suppliers or vendors as part of its
contingency plan.

Risks of the Company's Year 2000 Issues

      While the Company is attempting to minimize any negative consequences
arising from the year 2000 issue, there can be no assurance that year 2000
issues will not have a material adverse impact on the Company's business,
operations, or financial condition. While the Company expects that upgrades to
its internal business systems will be completed in a timely fashion, there can
be no assurance that the Company will not encounter unexpected costs or delays.
Despite its efforts to ensure that its material current products are year 2000
compliant, the Company may see an increase in warranty and other claims,
especially those related to Company products that incorporate, or operate using,
third-party software or hardware. In addition, certain of the Company's older
products, which it no longer manufactures or sells, may not be year 2000
compliant, which may expose the Company to claims. As discussed above, if any of
the Company's significant suppliers or vendors experience business disruptions
due to year 2000 issues, the Company might also be materially adversely
affected. There is expected to be a significant amount of litigation relating to
the year 2000 issue and there can be no assurance that the Company will not
incur material costs in defending or bringing lawsuits. In addition, if any year
2000 issues are identified, there can be no assurance that the Company will be
able to retain qualified personnel to remedy such issues. Any unexpected costs
or delays arising from the year 2000 issue could have a material adverse impact
on the Company's business, operations, and financial condition in amounts that
cannot be reasonably estimated at this time.

Item 3 - Quantitative and Qualitative Disclosures About Market Risk

      The Company's exposure to market risk from changes in foreign currency
exchange rates, interest rates, and equity prices has not changed materially
from its exposure at year-end 1998.

PART II - OTHER INFORMATION

Item 1 - Legal Proceedings

      On July 19, 1999, Bruker Daltronik GmbH filed a patent infringement
compliant against the Company and its German subsidiaries in the District Court
of Dusseldorf, Germany. The complaint alleges the Company is violating two of
Bruker's European patents. The patents pertain to ion-trap mass spectrometers.
The complaint requests damages to compensate for the alleged past infringement,
an injunction against future infringement, and costs. The Company intends to
vigorously defend this lawsuit; however, due to the inherent uncertainty of
litigation, the Company cannot predict the outcome of this matter.
