                                Notes to Consolidated Financial Statements

1.    General

      The interim consolidated financial statements presented have been prepared
by Thermo Instrument Systems Inc. (the Company) without audit and, in the
opinion of management, reflect all adjustments of a normal recurring nature
necessary for a fair statement of the financial position at April 1, 2000, and
the results of operations and cash flows for the three-month periods ended April
1, 2000, and April 3, 1999. Interim results are not necessarily indicative of
results for a full year.

      The consolidated balance sheet presented as of January 1, 2000, has been
derived from the consolidated financial statements that have been audited by the
Company's independent public accountants. The consolidated financial statements
and notes are presented as permitted by Form 10-Q and do not contain certain
information included in the annual financial statements and notes of the
Company. The consolidated financial statements and notes included herein should
be read in conjunction with the financial statements and notes included in the
Company's Annual Report on Form 10-K for the fiscal year ended January 1, 2000,
filed with the Securities and Exchange Commission.

2.    Comprehensive Income

      Comprehensive income combines net income and "other comprehensive items,"
which represents certain amounts that are reported as components of
shareholders' investment in the accompanying balance sheet, including foreign
currency translation adjustments and unrealized net of tax gains and losses on
available-for-sale investments. During the first quarter of 2000 and 1999, the
Company had comprehensive income of $0.8 million and a comprehensive loss of
$8.3 million, respectively.

3.    Earnings per Share (continued)

      The computation of diluted earnings per share for the first quarter of
2000 and 1999 excludes the effect of assuming the conversion of the Company's
$250.0 million principal amount 4% subordinated convertible debentures,
convertible at $35.65 per share, and $172.5 million principal amount 4 1/2%
senior convertible debentures, convertible at $34.46 per share, because the
effect would be antidilutive. In addition, options to purchase 355,000 and
449,000 shares of common stock were not included in the computation of diluted
earnings per share for the first quarter of 2000 and 1999, respectively, because
their effect would have been antidilutive due to the options' exercise prices
exceeding the average market price for the common stock.

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 the 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. Accrued acquisition expenses are included in other
accrued expenses in the accompanying balance sheet.

      A summary of the changes in accrued acquisition expenses for acquisitions
completed before and during 1997 is as follows:

      The principal accrued acquisition expenses for 1999 acquisitions are
severance for approximately 175 employees across all functions and for abandoned
facilities, primarily at Spectra-Physics AB. The abandoned facilities at
Spectra-Physics include operating facilities in Sweden, Germany, and France with
obligations through 2000. The amounts captioned as "other" primarily represent
relocation, contract termination, and other exit costs. The Company expects to
pay amounts accrued for severance and other primarily in 2000 and amounts
accrued for abandoned facilities over the respective lease terms. The Company
finalized its restructuring plans for Spectra-Physics in 1999. Unresolved
matters at April 1, 2000, included completion of planned severances and
abandonment of excess facilities for other acquisitions completed in 1999. Such
matters will be resolved no later than one year from the respective acquisition
dates.

6.    Restructuring Costs and Other Unusual Income

      During the first quarter of 2000, the Optical Technologies segment
recorded $12.4 million of unusual income resulting from the sale of its Nicolet
Imaging Systems (NIS) and Sierra Research and Technology, Inc. (SRT)
subsidiaries. The businesses manufacture products that include imaging systems
used in assembling complex printed circuit boards and in airbag manufacturing.
NIS and SRT were sold for aggregate proceeds of $40.0 million and had aggregate
revenues and operating income of $28.3 million and $2.2 million, respectively,
in 1999. These units were sold due to a consolidation trend among manufacturers
of test equipment in the markets these businesses serve. The Company has decided
to focus on growth in other sectors of the instruments market. During the first
quarter of 2000, this segment also recorded a noncash charge of $13.4 million
associated with its equity method investment in FLIR Systems, Inc., acquired as
part of the February 1999 acquisition of Spectra-Physics. FLIR recorded
significant charges in its fourth quarter of 1999 and the segment has recorded
its pro rata share of FLIR's loss. The segment records FLIR's results on a one
quarter lag. This charge was recorded to equity in losses of unconsolidated
subsidiaries in the accompanying statement of income. In addition, the Optical
Technologies segment recorded other noncash income of $1.7 million related to
hedging transactions of its majority-owned Spectra-Physics Lasers, Inc. (SPLI)
subsidiary, which elected early adoption of Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities."

      During 1998 and 1999, the Company and its subsidiaries recorded
restructuring costs, which were accounted for in accordance with EITF 94-3,
primarily for severance for 723 employees and abandoned-facility payments. As of
January 1, 2000, the Company had terminated 711 employees and during the first
quarter of 2000, the Company terminated 7 additional employees. As of January 1,
2000, the Company had $1.7 million accrued for severance and facility-closing
costs relating to these activities. During the first quarter of 2000, the
Optical Technologies segment reversed $0.1 million of previously established
restructuring reserves. The Company expects to incur additional restructuring
costs totaling $0.2 million in the remainder of 2000, which are not permitted as
charges until incurred pursuant to the requirements of EITF 94-3.

7.    Acquisition of Thermo Vision Minority Interest

      In July 1999, the Company's Thermo Vision Corporation subsidiary announced
that it had entered into a definitive agreement and plan of merger with the
Company pursuant to which the Company would acquire all of the outstanding
shares of common stock of Thermo Vision held by the public shareholders in
exchange for $7.00 per share in cash. The merger of Thermo Vision was completed
in January 2000 and its common stock has ceased to be publicly traded.

8.    Proposed Reorganization

      In January 2000, the Company announced plans to take private Thermo Optek
Corporation, ThermoQuest Corporation, Thermo BioAnalysis Corporation, Metrika
Systems Corporation, and ONIX Systems Inc. In addition, the Company announced
that Thermo Electron Corporation plans to take the Company private. These
actions are part of a major reorganization plan under which Thermo Electron will
spin in, spin off, and sell various businesses to focus solely on its core
measurement and detection instruments business. Because the Company owned more
than 90% of the outstanding shares of Thermo Optek and ThermoQuest common stock,
these two companies were spun in for cash through a "short-form" merger, at
$15.00 and $17.00 per share, respectively, during the second quarter of 2000 and
their common stock has ceased to be publicly traded. Also during the second
quarter of 2000, the Company successfully completed cash tender offers of $28.00
per share for Thermo BioAnalysis, $9.00 per share for Metrika Systems, and $9.00
per share for ONIX Systems, in order to bring its own equity ownership,
collective with Thermo Electron, in each of these companies to at least 90%. The
Company subsequently completed the acquisition of the outstanding minority
interest in each of these companies through short-form mergers at the same cash
prices as the tender offers and their common stock has ceased to be publicly
traded. As a result, the Company currently owns approximately 79.2%, 91.5%, and
97.9% of the outstanding shares of Thermo BioAnalysis, Metrika Systems, and ONIX
Systems common stock, respectively, and Thermo Electron currently owns
approximately 20.8%, 8.5%, and 2.1% of the outstanding shares of Thermo
BioAnalysis, Metrika Systems, and ONIX Systems common stock, respectively.

      During the second quarter of 2000, Thermo Electron commenced an exchange
offer for any and all of the outstanding shares of the Company's common stock
held by minority shareholders. The Company's shareholders would receive 0.85
shares of Thermo Electron common stock for each share of Company common stock
held. Thermo Electron, which currently owns approximately 88.6% of the
outstanding shares of the Company's common stock, has conditioned the exchange
offer on receiving acceptances from holders of enough shares so that, when
combined with its current share ownership, Thermo Electron's ownership reaches
at least 90%. If Thermo Electron achieves this 90%-ownership threshold, it will
acquire all remaining outstanding shares of the Company's common stock through a
short-form merger. In the short-form merger, minority shareholders who do not
participate in the exchange offer would also receive shares of Thermo Electron
common stock in exchange for their shares of the Company's common stock at the
same ratio.

                                       11
<PAGE>


8.    Proposed Reorganization (continued)

      The exchange offer will require Securities and Exchange Commission (SEC)
clearance of necessary filings. The exchange offer and subsequent short-form
merger of the Company with Thermo Electron would not require approval by the
Company's Board of Directors or shareholders.

      If Thermo Electron successfully obtains ownership of at least 90% of the
outstanding shares of the Company's common stock, it expects to complete the
spin-in of the Company by the end of the third quarter of 2000.

      Obligations under the Company's 4% subordinated convertible debentures due
January 15, 2005, and its 4 1/2% senior convertible debentures due October 15,
2003, would be assumed by Thermo Electron in the short-form merger, and the
debentures would be convertible into Thermo Electron common stock.

      SPLI, acquired indirectly by the Company as part of its February 1999
acquisition of Spectra-Physics, will remain a public subsidiary while the
Company and Thermo Electron continue to evaluate the SPLI business. The Company
owns approximately 78.5% of the outstanding shares of SPLI common stock.

9.    Conversion of Senior Convertible Note Due to Parent Company

      On February 15, 2000, the Company's $140.0 million principal amount 3 3/4%
senior convertible note, convertible at $13.55 per share, was converted by
Thermo Electron into 10,334,620 shares of Company common stock. Accordingly, the
note was classified as noncurrent in the accompanying 1999 balance sheet.

10.   Recent Accounting Pronouncement

      In December 1999, the SEC issued Staff Accounting Bulletin (SAB) 101,
"Revenue Recognition in Financial Statements." SAB 101 includes requirements for
when shipments may be recorded as revenue when the terms of the sale include
customer acceptance provisions or an obligation of the seller to install the
product. In such instances, SAB 101 generally requires that revenue recognition
occur upon customer acceptance and/or at completion of installation. SAB 101
requires that companies conform their revenue recognition practices to the
requirements therein no later than the second quarter of calendar 2000 through
recording a cumulative net of tax effect of the change in accounting as of
January 2, 2000. The Company has not yet completed the analysis to determine the
effect that SAB 101 will have on its financial statements.

11.   Subsequent Event

      On May 11, 2000, the Company announced that it had entered into an
agreement to sell its wholly owned Spectra Precision, Inc. businesses to Trimble
Navigation Limited for approximately $200 million in cash and $80 million in
seller debt financing. Spectra Precision, part of the Measurement and Control
segment, was acquired in February 1999 as part of Spectra-Physics and provides
the construction, surveying, and heavy machine industries with precision
positioning equipment. These businesses are being sold as they are outside the
Company's renewed focus on measurement and detection instrumentation. Closing of
the transaction, expected at the end of the second quarter of 2000, is subject
to regulatory approval, financing, and other customary conditions.

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
fiscal year ended January 1, 2000, filed with the Securities and Exchange
Commission.

Overview

      The Company is a worldwide leader in the development, manufacture, and
sale of measurement and detection instruments used in virtually every industry
to monitor, collect, and analyze data that provide knowledge for the user. For
example, the Company's powerful analysis technologies help researchers sift
through data to make the discoveries that will fight disease or prolong life;
allow manufacturers to fabricate ever-smaller components required to increase
the speed and quality of communications; or monitor and control industrial
processes on-line to ensure that critical quality standards are met efficiently
and safely.

      The Company's businesses operate in three instrumentation segments: Life
Sciences, Optical Technologies, and Measurement and Control. The Life Sciences
segment includes the Company's Thermo BioAnalysis Corporation and ThermoQuest
Corporation subsidiaries, as well as certain wholly owned subsidiaries. This
segment develops and manufactures systems for drug discovery and medical
diagnosis and for chemical analysis at ultratrace levels. The Optical
Technologies segment consists of Thermo Optek Corporation, ThermoSpectra
Corporation, Thermo Vision Corporation, Spectra-Physics Lasers, Inc. (SPLI), and
certain other wholly owned businesses. This segment develops and manufactures
optical and energy-based analytical systems; high-power laser systems; and
industrial imaging, inspection, and measurement instruments. The Measurement and
Control segment includes the Company's ONIX Systems Inc. and Metrika Systems
Corporation subsidiaries, as well as certain wholly owned subsidiaries,
including businesses of Spectra-Physics AB, acquired in February 1999. This
segment develops and manufactures on-line systems for industrial processes and
quality control, field-measurement instruments, and real-time sensors.

      International sales account for a significant portion of the Company's
total revenues. 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 short-term forward foreign exchange
contracts to reduce its exposure to currency fluctuations.

Results of Operations

First Quarter 2000 Compared With First Quarter 1999

      Revenues increased $57.5 million to $521.1 million in the first quarter of
2000 from $463.6 million in the first quarter of 1999. Revenues increased $53.6
million due to the inclusion of revenues from 1999 acquisitions for the full
period and an acquisition made in 2000, net of dispositions that reduced
revenues by $3.6 million. This increase in revenues was offset in part by a
decrease in revenues of $14.9 million due to the unfavorable effects of currency
translation as a result of the strengthening of the U.S. dollar relative to
foreign currencies in countries in which the Company operates. Excluding the
impact of acquisitions, dispositions, and currency translation, revenues
increased $18.8 million.

<PAGE>

First Quarter 2000 Compared With First Quarter 1999 (continued)

      Life Sciences segment revenues increased to $178.1 million in the first
quarter of 2000 from $169.2 million in the first quarter of 1999. Revenues
increased $7.5 million due to acquisitions. The unfavorable effects of currency
translation decreased revenues in this segment by $7.4 million. Excluding the
effect of acquisitions and currency translation, revenues increased $8.8
million. Revenues from pharmaceutical and biochemical research products
increased $3.9 million due to higher demand for the segment's immunoassay
testing and newly introduced Multiblock deoxyribonucleic acid (DNA)
amplification products. Revenues from analytical instruments increased $3.2
million due to higher sales of mass spectrometers in Europe and Asia. Revenues
from scientific equipment increased $2.2 million due to higher demand for
controlled-environment laboratory equipment. These increases in revenues were
offset in part by lower revenues from information management systems due to
lower demand in the U.S.

      Optical Technologies segment revenues increased to $198.0 million in the
first quarter of 2000 from $178.5 million in the first quarter of 1999. Revenues
increased $13.8 million due to acquisitions, net of dispositions, primarily the
acquisition of SPLI, in which the Company acquired a majority interest on
February 22, 1999. The dispositions primarily included the segment's Nicolet
Imaging Systems (NIS) and Sierra Research and Technology, Inc. (SRT) businesses
that were sold in March 2000 (Note 6). These units were sold due to a
consolidation trend among manufacturers of test equipment in the markets these
businesses serve. The Company has decided to focus on growth in other sectors of
the instruments market. The unfavorable effects of currency translation
decreased revenues in this segment by $5.4 million in 2000. Excluding the effect
of acquisitions, dispositions, and currency translation, revenues increased
$11.1 million. The increase in revenues was due in part to $4.6 million of
increased demand for products sold to the semiconductor industry by the
segment's physical properties business. The semiconductor sector is experiencing
renewed growth after a downturn in the first half of 1999. Revenues from
elemental analysis instruments increased $3.2 million in 2000, primarily due to
new product introductions, and revenues from photonics products increased $2.8
million, primarily due to strong demand for gratings used in systems for
semiconductor manufacturers and in telecommunications.

      Measurement and Control segment revenues increased to $147.7 million in
the first quarter of 2000 from $118.7 million in the first quarter of 1999.
Revenues increased $32.3 million due to acquisitions, primarily that of
Spectra-Physics AB's wholly owned businesses, acquired on February 22, 1999. The
unfavorable effects of currency translation decreased revenues in this segment
by $2.1 million. Excluding the effect of acquisitions and currency translation,
revenues decreased $1.2 million. Revenues from process control products
decreased $1.5 million, primarily as a result of reduced discretionary capital
spending by companies in the process control industry and by the oil and gas
production sector. Revenues from process-optimization systems decreased $1.2
million, primarily due to a reduction in spending in the metals industry due to
depressed pricing. These decreases in revenues were offset in part by higher
revenues from the sale of environmental-monitoring instruments.

      The gross profit margin increased to 47% in the first quarter of 2000 from
46% the first quarter of 1999. The 1999 period included lower-margin revenues
from Spectra-Physics, which recorded a charge of $4.6 million relating to the
sale of inventories revalued at the date of acquisition, of which $3.2 million
was recorded by the Measurement and Control segment and $1.4 million by the
Optical Technologies segment. Excluding the charge for the sale of revalued
inventories in 1999, the gross profit margin remained unchanged at 47% in 2000
and 1999.

      Selling, general, and administrative expenses as a percentage of revenues
increased to 29% in the first quarter of 2000 from 28% in the first quarter of
1999, principally due to the inclusion of higher selling, general, and
administrative expenses as a percentage of revenues at the wholly owned
businesses of Spectra-Physics.

      Research and development expenses increased to $44.8 million in the first
quarter of 2000 from $34.2 million in the first quarter of 1999, primarily due
to the inclusion of expenses at Spectra-Physics and, to a lesser extent, other
acquired businesses. In addition, research and development expenses increased
due to spending on new product development, including the V150 molecular beam
epitaxy system. Research and development expenses as a percentage of revenues
were 8.6% in 2000, compared with 7.4% in 1999. Excluding the expenses at
acquired businesses, research and development expenses as a percentage of
revenues were 7.7% in 2000.

First Quarter 2000 Compared With First Quarter 1999 (continued)

      The Optical Technologies segment recorded unusual income of $12.4 million
in the first quarter of 2000 resulting from the sale of NIS and SRT (Note 6). In
connection with the restructuring actions undertaken by the Company in 1998,
this segment reversed previously established restructuring reserves of $0.1
million in the first quarter of 2000. In connection with the closing of certain
facilities, the Company expects to incur approximately $0.2 million of
additional costs in 2000.

      Interest income decreased to $5.9 million in the first quarter of 2000
from $6.3 million in the first quarter of 1999, primarily due to a reduction in
invested balances as a result of acquisitions, including the acquisition of
Spectra-Physics in February 1999.

      Interest expense increased to $12.6 million in the first quarter of 2000
from $12.2 million in the first quarter of 1999, primarily due to borrowings
from Thermo Electron Corporation in connection with the acquisition of
Spectra-Physics. This increase was offset in part by a decrease in interest
expense as a result of the repayment of certain promissory notes to Thermo
Electron that were issued in connection with acquisitions and the conversion by
Thermo Electron of the Company's $140.0 million principal amount 3 3/4% senior
convertible note in February 2000 (Note 9).

      Equity in losses of unconsolidated subsidiaries of $13.4 million in the
first quarter of 2000 primarily relates to charges associated with
Spectra-Physics' minority investment in FLIR Systems, Inc., which recorded
significant charges in its fourth quarter of 1999. The Company reports its pro
rata share of FLIR's results on a one quarter lag (Note 6).

      Other income (expense), net, in the first quarter of 2000 and 1999
primarily represents currency gains and losses resulting from hedging activities
at SPLI, which elected early adoption of Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" (Note 6).

      The effective tax rate was 45% in the first quarter of 2000, compared with
41% in the first quarter of 1999. The effective tax rate exceeded the statutory
federal income tax rate in both periods due to foreign tax rate and tax law
differences, nondeductible amortization of cost in excess of net assets of
acquired companies, and the impact of state income taxes. The effective tax rate
increased in 2000 primarily due to the tax benefit for the loss at FLIR being
recorded at 28%, the tax rate of the Swedish subsidiary that holds the
investment in FLIR.

      Minority interest expense remained relatively unchanged at $4.5 million in
the first quarter of 2000 and $4.3 million in the first quarter of 1999.

Liquidity and Capital Resources

      Consolidated working capital was $410.2 million at April 1, 2000, compared
with $368.8 million at January 1, 2000. Included in working capital are cash and
cash equivalents of $188.6 million at April 1, 2000, compared with $185.5
million at January 1, 2000. Of the cash and cash equivalents balance at April 1,
2000, $149.1 million was held by the Company's majority-owned subsidiaries and
the balance was held by the Company and its wholly owned subsidiaries. In
addition, as of April 1, 2000, the Company had $274.3 million invested in an
advance to affiliate. Of the advance to affiliate at April 1, 2000, $270.7
million was held by the Company's majority-owned subsidiaries and the balance
was advanced by the Company and its wholly owned subsidiaries. At April 1, 2000,
$149.6 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,
for activities including acquisitions, repatriation of this cash into the United
States would be subject to foreign withholding taxes and could also be subject
to a United States tax. Also reflected in working capital are $153.8 million of
short-term obligations and current maturities of long-term obligations due to
Thermo Electron in 2000 and an aggregate $130.0 million principal amount of
ThermoQuest and Thermo Optek 5% subordinated convertible debentures due August
and October 2000, respectively. Of the $153.8 million due to Thermo Electron,
$150.0 million represents a promissory note due August 2000.


                                       15
<PAGE>

Liquidity and Capital Resources (continued)

      Cash provided by operating activities was $17.1 million in the first three
months of 2000. A decrease in accounts receivable provided cash of $12.7
million, primarily in the Optical Technologies and Life Sciences segments due to
lower sales volume in the first quarter of 2000, compared with the fourth
quarter of 1999. Cash of $32.4 million was used to fund an increase in
inventories, primarily in the Optical Technologies and Life Sciences segments
due to a build-up of inventory in preparation of new product releases and the
replenishment of year-end inventory levels. Cash of $5.7 million was used to
fund a decrease in accounts payable and other current liabilities, primarily due
to the timing of payments, offset in part by an increase in deferred revenue,
primarily in the Optical Technologies and Life Sciences segments due to annual
service contract billings in the first quarter of 2000. As of April 1, 2000, the
Company had $1.2 million of accrued restructuring costs, primarily all of which
it expects to pay in 2000. As of April 1, 2000, the Company had accrued $17.0
million for acquisition expenses. Accrued acquisition expenses includes $4.1
million of severance obligations, which the Company expects to pay primarily in
2000. The balance, which primarily represents abandoned-facility payments, will
be paid over the remaining terms of the leases through 2014.

      During the first three months of 2000, the Company's primary investing
activities, excluding advance to affiliate activity, included the acquisition of
the minority interest of Thermo Vision, dispositions, and the purchase of
property, plant, and equipment. During the first three months of 2000, the
Company expended $11.2 million to acquire the minority interest of Thermo Vision
(Note 7) and expended an additional $0.3 million related to the acquisition of
the minority interest of ThermoSpectra, which was completed in December 1999.
The Company will expend additional cash of approximately $260 million, primarily
in the second quarter of 2000, for the repurchases of the public shares that it
does not already own of its majority-owned subsidiaries, excluding SPLI (Note
8). The Company received aggregate net proceeds of $38.5 million, net of cash
divested, from the sale of NIS and SRT in March 2000 (Note 6). The Company
expended $12.6 million for purchases of property, plant, and equipment and $4.7
million, net of cash acquired, for an acquisition. During the remainder of 2000,
the Company plans to make expenditures of approximately $53 million for
property, plant, and equipment.

      The Company's financing activities used $13.5 million of cash in the first
three months of 2000, primarily as a result of the repayment of $22.1 million of
short- and long-term obligations.

      On May 11, 2000, the Company announced that it had entered into an
agreement to sell its wholly owned Spectra Precision, Inc. businesses to Trimble
Navigation Limited for approximately $200 million in cash and $80 million in
seller debt financing (Note 11).

      The Company has short-term obligations and current maturities of long-term
obligations due to Thermo Electron primarily in August 2000, totaling $153.8
million at April 1, 2000. In addition, ThermoQuest's $61.0 million and Thermo
Optek's $69.0 million principal amount 5% subordinated convertible debentures
are due in August and October 2000, respectively, although earlier repayment is
expected upon completion of the transactions discussed in Note 8. The Company
has an agreement with Thermo Electron under which the Company may borrow up to
$400 million on a short-term basis in connection with the acquisition of the
minority interest of its publicly held subsidiaries, excluding SPLI, and the
redemption of the subsidiary debentures. As of May 12, 2000, the Company has
borrowed $231 million under this agreement. Thermo Electron has indicated that
it will seek repayment from the Company of such borrowings, in addition to the
Company's $150.0 million promissory note, only to the extent the Company's cash
flow permits such repayments. Excluding such debt and the 5% subordinated
convertible debentures of ThermoQuest and Thermo Optek, the Company believes
that its existing resources are sufficient to meet the capital requirements of
its existing operations for the foreseeable future. The Company has historically
complemented internal development with acquisitions of businesses or
technologies that extend the Company's presence in current markets or provide
opportunities to enter and compete effectively in new markets. The Company will
consider making acquisitions of such businesses or technologies that are
consistent with its plans for strategic growth. The Company expects that it will
finance these acquisitions through a combination of internal funds, and/or
short-term borrowings from Thermo Electron although there is no agreement with
Thermo Electron to ensure that funds will be available on acceptable terms or at
all.

be held each year on such  date and at such time as the Board of  Directors  may
determine.  At each annual meeting the stockholders entitled to vote shall elect
a Board of  Directors by plurality  vote by ballot,  and they may transact  such
other corporate  business as may properly be brought before the meeting.  At the
annual  meeting any  business  may be  transacted,  irrespective  of whether the

where  notice is required by law, the  certificate  of  incorporation,  or these
by-laws.

      Section 2.3. Quorum.  At all meetings of the stockholders the holders of a

originally called.


<PAGE>


      Section 2.4. Right to Vote, Proxies.  Each stockholder having the right to

either in person or by proxy,  but no proxy which is dated more than three years
prior to the  meeting  at which it is  offered  shall  confer  the right to vote
thereat  unless  the  proxy  provides  that it shall be  effective  for a longer
period. Every proxy shall be in writing, subscribed by a stockholder or his duly
authorized  attorney in fact, and dated, but need not be sealed,  witnessed,  or
acknowledged.

      Section  2.5.  Record  Date.  Except  where  the  transfer  books  of  the

meeting of the stockholders shall be mailed to each stockholder entitled to vote
thereat at such  address as appears  on the stock  books of the  corporation  at

shall  be the duty of every  stockholder  to  furnish  to the  Secretary  of the
corporation  or to the  transfer  agent,  if any, of the class of stock owned by
him, his  post-office  address and to notify said Secretary or transfer agent of
any change therein.

      Section  2.8.  Stockholders'  List.  A complete  list of the  stockholders
entitled to vote at any meeting of stockholders,  arranged in alphabetical order
and showing the address of each stockholder, and the number of shares registered
in the name of each  stockholder,  shall be prepared by the  Secretary and filed
either at a place  within the city where the meeting is to be held,  which place
shall be specified in the notice of the meeting, or, if not so specified, at the
place  where the meeting is to be held,  at least ten days before such  meeting,
and shall at all times during the usual hours for business, and during the whole
time of said  election,  be open to the  examination  of any  stockholder  for a
purpose germane to the meeting.

address  as  appears  on  the  books  of the  corporation.  No  business  may be
transacted  at such  meeting  except that  referred to in said  notice,  or in a
supplemental notice given also in compliance with the provisions hereof, or such
other business as may be germane or  supplementary to that stated in said notice
or notices.


<PAGE>


      Section  2.11.  Stockholders'  Action  by  Consent.  Whenever  the vote of
stockholders  at a meeting  thereof  is  required  or  permitted  to be taken in
connection  with any corporate  action by any  provisions  of the statutes,  the
certificate  of  incorporation,  or  these  by-laws,  the  meeting  and  vote of
stockholders  may be dispensed with, and any corporate  action upon which a vote
of  stockholders  is required or permitted may be taken with the written consent
of  stockholders  having not less than 50% of all of the stock  entitled to vote
upon the  action if a meeting  were  held;  provided  that in no case  shall the
written  consent be by holders  having less than the minimum  percentage  of the
total vote  required by statute for the proposed  corporate  action and provided
that prompt notice be given to all  stockholders of the taking of such corporate
action without a meeting and by less than unanimous consent.


                             ARTICLE III- DIRECTORS

      Section 3.1. Number of Directors. Except as otherwise provided by law, the
certificate of incorporation or these by-laws,  the property and business of the
corporation  shall be managed by or under the  direction  of a board of not less
than two nor more than  thirteen  directors.  Within the limits  specified,  the
number of directors  shall be determined by resolution of the Board of Directors
or  by  the   stockholders  at  the  annual  meeting.   Directors  need  not  be
stockholders.  The directors shall be elected by ballot at the annual meeting of
the stockholders and each director shall be elected to serve until his successor
shall be elected and shall qualify or until his earlier  resignation or removal;
provided  that in the  event of  failure  to hold such  meeting  or to hold such
election at such meeting,  such  election may be held at any special  meeting of
the stockholders  called for that purpose. If the office of any director becomes
vacant by reason of death,  resignation,  disqualification,  removal, failure to
elect, or otherwise, the remaining directors,  although less than a quorum, by a
majority  vote of such  remaining  directors may elect a successor or successors
who shall hold office for the unexpired term or until their earlier  resignation
or  removal.  Vacancies  and  newly  created  directorships  resulting  from any
increase in the  authorized  number of directors  may be filled by a majority of
the  directors  then  in  office,  although  less  than a  quorum,  or by a sole
remaining director, and the directors so chosen shall hold office until the next
annual  election and until their  successors  are elected and qualified or until
their earlier resignation or removal.

      Section 3.2. Change in Number of Directors;  Vacancies. The maximum number
of directors  may be increased  by an  amendment to these  by-laws  adopted by a
majority  vote of the Board of  Directors  or by a majority  vote of the capital
stock  having  voting  power,  and if the number of directors is so increased by
action of the Board of Directors or of the  stockholders or otherwise,  then the
additional  directors  may be elected in the manner  provided  in Section 3.1 of

shall thereupon be issued. The corporation shall be entitled to treat the holder
of record of any share or  shares  of stock as the  holder in fact  thereof  and
accordingly  shall not be bound to recognize  any equitable or other claim to or
interest in such share on the part of any other  person  whether or not it shall
have express or other notice  thereof save as expressly  provided by the laws of
Delaware.


<PAGE>

capital stock is to occur,  and in such case only such  stockholders as shall be
stockholders of record on the date so fixed shall be entitled to such notice of;
and to vote at, such  meeting,  or to receive  payment of such  dividend,  or to

stock,  subject to the provisions of the  certificate of  incorporation  and the
laws of Delaware.

      2. Reserves. Before payment of any dividend, there may be set aside out of
any funds of the  corporation  available for  dividends  such sum or sums as the
directors  from time to time, in their  absolute  discretion,  think proper as a
reserve or reserves to meet contingencies,  or for equalizing dividends,  or for
repairing  or  maintaining  any property of the  corporation,  or for such other
purpose  as  the  directors  shall  think  conducive  to  the  interest  of  the
corporation,  and the  directors  may modify or abolish any such  reserve in the
manner in which it was created.

      Section 5.6. Lost, Stolen or Destroyed  Certificates.  No certificates for
shares of stock of the  corporation  shall be issued in place of any certificate
alleged to have been lost,  stolen or destroyed,  except upon production of such

corporation  and its agents to such  extent  and in such  manner as the Board of
Directors may from time to time prescribe.

a majority  vote at any  meeting of  stockholders  duly  called,  or in case the

and under what conditions and  regulations  and books of the corporation  (other
than  the  stock  ledger)  or any of  them,  shall  be  open  to  inspection  of
stockholders;  and no stockholder shall have any right to inspect any account or
book or  document  of the  corporation  except as  conferred  by the  statute or

statutes or of the certificate of  incorporation  or of these bylaws,  a written
waiver of  notice,  signed by the  person or persons  entitled  to said  notice,
whether before or after the time stated therein,  shall be deemed  equivalent to
notice. Attendance of a person at a meeting, or, in the case of a meeting of the
Board of Directors,  participation in a meeting by means of conference telephone
or similar communications equipment, shall constitute a waiver of notice of such
meeting except when the person attends,  or  participates  in, a meeting for the
express  purpose  of  objecting,  at  the  beginning  of  the  meeting,  to  the
transaction  of any  business  because  the  meeting is not  lawfully  called or
convened.

      Section 6.3. Conflict of Interest.  No contract or transaction between the
corporation  and  one or more of its  directors  or  officers,  or  between  the
corporation  and any  other  corporation,  partnership,  association,  or  other
organization  in which one or more of its directors or officers are directors or
officers,  or have a financial  interest,  shall be void or voidable  solely for
this  reason,  or solely  because  the  director  or  officer  is  present at or
participates in the meeting of the Board of Directors or committee thereof which
authorizes the contract or transaction, or solely because his or their votes are
counted  for  such  purpose  if (i)  the  material  facts  as to  his  or  their
relationship  or interest and as to the contract or transaction are disclosed or
are known to the Board of Directors or the committee, and the Board of Directors
or  committee  in good faith  authorizes  the  contract  or  transaction  by the
affirmative votes of a majority of the disinterested directors,  even though the
disinterested  directors be less than a quorum; or (ii) the material facts as to
his or their  relationship or interest and as to the contract or transaction are
disclosed or are known to the  shareholders  entitled to vote  thereon,  and the
contract or  transaction is  specifically  approved in good faith by vote of the
shareholders; or (iii) the contract or transaction is fair as to the corporation
as of  the  time  it is  authorized,  approved  or  ratified,  by the  Board  of
Directors,  a  committee  thereof  or the  shareholders.  Common  or  interested
directors may be counted in determining the presence of a quorum at a meeting of
the Board of  Directors  or of a  committee  which  authorizes  the  contract or
transaction.

other  corporation by the President of this corporation if he is present at such
meeting, or in his absence by the Treasurer of this corporation if he is present
at such  meeting,  and (b)  whenever,  in the judgment of the  President,  it is
desirable for this  corporation to execute a proxy or written consent in respect
to any shares or other securities  issued by any other  corporation and owned by
this  corporation,  such proxy or consent  shall be executed in the name of this
corporation by the President,  without the necessity of any authorization by the
Board  of  Directors,  affixation  of  corporate  seal  or  countersignature  or
attestation  by another  officer,  provided  that if the  President is unable to
execute  such proxy or consent by reason of  sickness,  absence  from the United
States or other similar cause,  the Treasurer may execute such proxy or consent.
Any person or persons  designated  in the  manner  above  stated as the proxy or
proxies of this corporation  shall have full right,  power and authority to vote
the shares or other  securities  issued by such other  corporation  and owned by
this  corporation the same as such shares or other  securities might be voted by
this corporation.


                          ARTICLE VII- INDEMNIFICATION

than those by or in the Right of the  Corporation.  Subject to Section 3 of this
Article VII, the corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding,  whether civil,  criminal,  administrative  or investigative
(other than an action by or in the right of the  corporation),  by reason of the
fact  that  he  is or  was  a  director,  officer,  employee  or  agent  of  the
corporation,  or is or was  serving  at the  request  of  the  corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by him in connection  with such action,  suit or proceeding if he acted
in good faith and in a manner he reasonably  believed to be in or not opposed to
the best interests of the corporation,  and, with respect to any criminal action
or proceeding,  had no reasonable cause to believe his conduct was unlawful. The
termination of any action,  suit or proceeding by judgment,  order,  settlement,
conviction,  or upon a plea of nolo contendere or its equivalent,  shall not, of
itself;  create a presumption that the person did not act in good faith and in a
manner  which  he  reasonably  believed  to be in or not  opposed  to  the  best
interests  of the  corporation,  and,  with  respect to any  criminal  action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

      Section 7.2. Power to Indemnify in Actions,  Suits or Proceedings by or in
the Right of the  Corporation.  Subject to Section 3 of this  Article  VII,  the
corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened,  pending or completed action or suit by or in
the right of the corporation to procure a judgment in its favor by reason of the
fact  that  he  is or  was  a  director,  officer,  employee  or  agent  of  the
corporation,  or is or was  serving  at the  request  of  the  corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other enterprise against expenses (including attorneys' fees)
actually  and  reasonably  incurred  by him in  connection  with the  defense or
settlement  of such  action or suit if he acted in good faith and in a manner he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
corporation;  except  that no  indemnification  shall be made in  respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable  to the  corporation  unless  and only to the  extent  that the  Court of
Chancery or the court in which such action or suit was brought  shall  determine
upon application that,  despite the adjudication of liability but in view of all
the circumstances of the case, such person is fairly and reasonably  entitled to
indemnity  for such  expenses  which the Court of  Chancery  or such other court
shall deem proper.


<PAGE>


      Section 7.3.  Authorization of Indemnification.  Any indemnification under
this Article VII (unless  ordered by a court)  shall be made by the  corporation
only  as   authorized   in  the  specific   case  upon  a   determination   that
indemnification  of the  director,  officer,  employee or agent is proper in the
circumstances because he has met the applicable standard of conduct set forth in
Section  1 or  Section  2 of  this  Article  VII,  as  the  case  may  be.  Such
determination  shall be made (i) by the Board of Directors by a majority vote of
a quorum  consisting of directors  who were not parties to such action,  suit or
proceeding, or (ii) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested  directors so directs, by independent legal counsel in a
written opinion, or (iii) by the stockholders.  To the extent,  however,  that a
director,  officer,  employee or agent of the corporation has been successful on
the merits or otherwise in defense of any action,  suit or proceeding  described
above,  or in  defense  of any  claim,  issue  or  matter  therein,  he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith,  without the necessity of authorization
in the specific case.

      Section 7.4. Good Faith Defined.  For purposes of any determination  under
Section 3 of this  Article  VII, a person  shall be deemed to have acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests  of the  corporation,  or,  with  respect  to any  criminal  action or
proceeding, to have had no reasonable cause to believe his conduct was unlawful,
if his action is based on the records or books of account of the  corporation or
another  enterprise,  or on  information  supplied to him by the officers of the
corporation  or  another  enterprise  in the course of their  duties,  or on the
advice  of  legal  counsel  for the  corporation  or  another  enterprise  or on
information  or records  given or  reports  made to the  corporation  or another
enterprise by an independent  certified public  accountant or by an appraiser or
other  expert  selected  with  reasonable  care by the  corporation  or  another
enterprise.  The term "another  enterprise" as used in this Section 4 shall mean
any  other  corporation  or any  partnership,  joint  venture,  trust  or  other
enterprise  of  which  such  person  is or was  serving  at the  request  of the
corporation as a director,  officer,  employee or agent.  The provisions of this
Section  4 shall  not be  deemed  to be  exclusive  or to  limit  in any way the
circumstances  in  which a  person  may be  deemed  to have  met the  applicable
standard  of conduct set forth in  Sections 1 or 2 of this  Article  VII, as the
case may be.

      Section  7.5.  Indemnification  by a Court.  Notwithstanding  any contrary
determination  in the  specific  case under  Section 3 of this  Article VII, and
notwithstanding  the  absence of any  determination  thereunder,  any  director,
officer,  employee or agent may apply to any court of competent  jurisdiction in
the State of Delaware for  indemnification  to the extent otherwise  permissible
under Sections 1 and 2 of this Article VII. The basis of such indemnification by
a court  shall be a  determination  by such  court that  indemnification  of the
director,  officer,  employee or agent is proper in the circumstances because he
has met the applicable standards of conduct set forth in Sections 1 or 2 of this
Article VII, as the case may be. Notice of any application  for  indemnification
pursuant to this Section 5 shall be given to the  corporation  promptly upon the
filing of such application.

      Section 7.6.  Expenses Payable in Advance.  Expenses incurred in defending
or investigating a threatened or pending action,  suit or proceeding may be paid
by the corporation in advance of the final  disposition of such action,  suit or
proceeding  as  authorized  by the Board of Directors in the specific  case upon
receipt of an undertaking by or on behalf of the director,  officer, employee or
agent to repay such amount unless it shall  ultimately be determined  that he is
entitled to be indemnified by the corporation as authorized in this Article VII.

      Section  7.7.   Non-Exclusivity  of  Indemnification  and  Advancement  of
Expenses. The indemnification and advancement of expenses provided by or granted
pursuant to this  Article VII shall not be deemed  exclusive of any other rights
to which  those  seeking  indemnification  or  advancement  of  expenses  may be
entitled  under  any  By-Law,  agreement,  contract,  vote  of  stockholders  or
disinterested directors or pursuant to the direction (howsoever embodied) of any
court of competent jurisdiction or otherwise,  both as to action in his official
capacity and as to action in another  capacity  while  holding  such office,  it
being  the  policy  of the  corporation  that  indemnification  of  the  persons
specified  in Sections 1 and 2 of this  Article VII shall be made to the fullest
extent  permitted by law. The provisions of this Article VII shall not be deemed
to preclude the indemnification of any person who is not specified in Sections 1
or 2 of this Article VII but whom the corporation has the power or obligation to
indemnify  under the provisions of the General  Corporation  Law of the State of
Delaware, or otherwise.

      Section  7.8.  Insurance.   The  corporation  may  purchase  and  maintain
insurance on behalf of any person who is or was a director, officer, employee or
agent of the  corporation or is or was serving at the request of the corporation
as a director,  officer, employee or agent of another corporation,  partnership,
joint venture,  trust or other enterprise against any liability asserted against
him and  incurred by him in any such  capacity,  or arising out of his status as
such,  whether or not the corporation  would have the power or the obligation to
indemnify him against such liability under the provisions of this Article VII.

      Section  7.9.  Meaning of  "Corporation"  for Purposes of Article VII. For
purposes of this Article VII,  references to "the corporation" shall include, in
addition to the resulting  corporation,  any constituent  corporation (including
any constituent of a constituent)  absorbed in a consolidation  or merger which,
if its separate  existence had continued,  would have had power and authority to
indemnify its directors,  officers,  and employees or agents, so that any person
who is or was a  director,  officer,  employee  or  agent  of  such  constituent
corporation, or is or was serving at the request of such constituent corporation
as a director,  officer, employee or agent of another corporation,  partnership,
joint venture, trust or other enterprise, shall stand in the same position under
the  provisions  of this Article VII with respect to the  resulting or surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

      Section 7.10. Survival of Indemnification and Advancement of Expenses. The
indemnification and advancement of expenses provided by, or granted pursuant to,
this Section  shall,  unless  otherwise  provided  when  authorized or ratified,
continue  as to a person who has ceased to be a director,  officer,  employee or
agent and shall inure to the benefit of the heirs,  executors and administrators
of such a person.

      Section  7.11.  Severabilitv.  If any word,  clause or  provision  of this
Article VII or any award made hereunder shall for any reason be determined to be
invalid, the provisions hereof shall not otherwise be affected thereby but shall
remain in full force and effect.

      Section  7.12.  Intent of  Article.  The intent of this  Article VII is to
provide for  indemnification  to the fullest extent permitted by applicable law,
including Section 145 of the General Corporation Law of Delaware.  To the extent
that such Section or any successor  Section may be amended or supplemented  from
time to time, this Article VII shall be amended  automatically  and construed so
as to permit  indemnification  to the fullest extent from time to lime permitted
by law.


                            ARTICLE VIII- AMENDMENTS

      Section 8.1.  Amendments.  The by-laws of the  corporation may be altered,
amended or repealed at any meeting of the Board of Directors upon notice thereof
in accordance with these by-laws,  or at any meeting of the  stockholders by the
vote of the holders of the  majority  of the stock  issued and  outstanding  and
entitled to vote at such  meeting,  in  accordance  with the  provisions  of the
certificate of incorporation and of the laws of Delaware.
