                   Notes to Consolidated Financial Statements

1.    General

      The interim consolidated financial statements presented have been prepared
by Thermo Electron Corporation (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 July 3, 1999, the results of
operations for the three- and six-month periods ended July 3, 1999, and July 4,
1998, and the cash flows for the six-month periods ended July 3, 1999, and July
4, 1998. Certain prior period amounts have been reclassified to conform to the
presentation in the current financial statements. Interim results are not
necessarily indicative of results for a full year.

      The consolidated balance sheet presented as of January 2, 1999, 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 2, 1999,
filed with the Securities and Exchange Commission.

2.    Comprehensive Income

      Comprehensive income combines net income (loss) 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 second quarter of 1999 and 1998, the
Company had a comprehensive loss of $247.9 million and comprehensive income of
$57.9 million, respectively. During the first six months of 1999 and 1998, the

      The computation of diluted loss per share for the second quarter and first
six months of 1999 excludes the effect of assuming the conversion of the
Company's $585.0 million principal amount 4 1/4% subordinated convertible
debentures, convertible at $37.80 per share, and the effect of assuming the
exercise of outstanding stock options, because the effect would be antidilutive
due to the Company's net loss. As of July 3, 1999, there were 11,952,000 of such
options outstanding, with exercise prices ranging from $8.85 to $43.46 per
share. In addition, the computation of diluted loss per share for the second
quarter and first six months of 1999 excludes the effect of assuming the
repurchase of 5,701,000 shares of Company common stock at a weighted average
exercise price of $14.56 per share in connection with put options sold to an
institutional counterparty, because the effect would be antidilutive.

      During 1998, the Company recorded extraordinary gains in connection with
the repurchase of subsidiary subordinated convertible debentures, which
increased basic and diluted earnings per share by $.01 in the second quarter of
1998 and $.02 in the first six months of 1998.

6.    Acquisitions

      During the first quarter of 1999, Thermo Instrument acquired 17,494,684
shares (or approximately 99%) of Spectra-Physics AB, a Stockholm Stock
Exchange-listed company, for approximately 160 Swedish krona per share
(approximately $20 per share) in completion of Thermo Instrument's cash tender
offer to acquire all of the outstanding shares of Spectra-Physics. Thermo
Instrument expects to acquire the remaining Spectra-Physics shares outstanding
for approximately 160 Swedish krona per share pursuant to the compulsory
acquisition rules applicable to Swedish companies, of which certain shares were
acquired in the second quarter of 1999. The aggregate purchase price was
approximately $347.2 million, including related expenses. On the date of
acquisition, Spectra-Physics had $39.1 million of cash, which included $30.5
million held by its majority-owned subsidiary. The accompanying July 3, 1999,
balance sheet includes $2.2 million accrued for the purchase of the remaining
Spectra-Physics shares outstanding. Spectra-Physics manufactures a wide range of
laser-based instrumentation systems, primarily for the process-control,
industrial measurement, construction, research, commercial, and government
markets. Spectra-Physics had revenues of approximately $442 million in 1998,
with operations throughout North America and Europe, and a presence in the
Pacific Rim.

      In connection with the acquisition of Spectra-Physics, Thermo Instrument
acquired 4,162,000 shares of FLIR Systems, Inc. common stock. FLIR designs,
manufactures, and markets thermal imaging and broadcast camera systems which
detect infrared radiation or heat emitted directly by all objects and materials.
The investment in FLIR shares represented 29.4% of FLIR's outstanding shares as
of July 3, 1999. Thermo Instrument accounts for its investment in FLIR on the
equity method with a one quarter lag to ensure the availability of FLIR's
operating results in time to enable Thermo Instrument to include its pro rata
share of FLIR's results with its own. During the first calendar quarter of 1999,
FLIR recorded a loss in connection with a pooling-of-interests transaction and
certain restructuring actions. Thermo Instrument has recorded its pro rata share
of this loss, $5.1 million, in equity in loss of unconsolidated subsidiaries, a
component of other income (expense), net in the accompanying statement of
operations. In addition, as a result of the pooling consummated by FLIR and
related issuance of FLIR shares in March 1999, Thermo Instrument's pro rata
share of FLIR's equity decreased. This decrease totaled $6.0 million and has
been recorded as a nonrecurring loss in equity in loss of unconsolidated
subsidiaries in the accompanying statement of operations, pursuant to Securities
and Exchange Commission Staff Accounting Bulletin 51.

      In addition, the Company and its majority-owned subsidiaries made several
other acquisitions during the first six months of 1999 for $37.1 million in
cash, net of cash acquired, subject to certain post-closing adjustments. To
date, no information has been gathered that would cause the Company to believe
that the post-closing adjustments will be material.

      These acquisitions have been accounted for using the purchase method of
accounting, and their results have been included in the accompanying financial
statements from their respective dates of acquisition. The aggregate cost of
these acquisitions exceeded the estimated fair value of the acquired net assets
by $157.1 million, which is being amortized over periods not exceeding 40 years.
Allocation of the purchase price for these acquisitions was based on estimates
of the fair value of the net assets acquired and is subject to adjustment upon
finalization of the purchase price allocations. The Company has gathered no
information that indicates the final allocations will differ materially from the
preliminary estimates. Pro forma results have not been presented as the results
of the acquired businesses were not material to the Company's results of
operations.

      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. Unresolved matters at July 3, 1999, primarily included completion
of planned severances and abandonment of excess facilities for certain
acquisitions

7.    Restructuring and Related Costs

      During the second quarter of 1999, the Company and certain of its
subsidiaries initiated broad scale restructuring actions affecting a number of
business units. As a result, the Company recorded restructuring and related
costs totaling $418.8 million and other nonoperating charges totaling $24.9
million. Restructuring and related costs include $369.9 million of restructuring
costs, $21.4 million of other nonrecurring costs, $25.3 million of inventory and
warranty provisions, and $2.3 million of provisions for uncollectible accounts
receivable. The inventory and warranty provisions are included in cost of
revenues, and the provisions for uncollectible accounts receivable are included
in selling, general, and administrative expenses in the accompanying statement
of operations. Other nonoperating charges include $22.5 million of other
expense, net and $2.5 million of income tax expense as detailed by segment
below. Severance and lease costs, recorded as components of restructuring costs,
were accounted for in accordance with EITF 94-3.

      In addition, during the first quarter of 1999, the Company and certain of
its subsidiaries recorded restructuring and related costs of $4.0 million,
including $5.6 million of restructuring costs, $8.6 million of other
nonrecurring income, net, and $7.0 million of inventory charges.

      The components of restructuring and related costs by segment and, where
applicable, by majority-owned subsidiary, are as follows:

Measurement and Detection

Thermedics Inc.

      Thermedics recorded restructuring and related costs of $32.5 million
during the second quarter of 1999 relating to the Measurement and Detection
segment, including restructuring costs of $30.1 million, other nonrecurring
costs of $0.1 million, a tax asset write-off of $1.4 million, and inventory
provisions of $0.9 million. Restructuring costs of $30.1 million relate to a
decision to sell its power electronics and test equipment business and include
$28.5 million to write off related cost in excess of net assets of acquired
companies to reduce the carrying value of the business to the

                                       13


7.    Restructuring and Related Costs (continued)

estimated proceeds from its sale. In addition, restructuring costs include a
charge of $1.6 million recorded by Thermedics to write off its remaining net
investment in a subsidiary of the power electronics and test equipment business,
which Thermedics intends to transfer to a buyer in consideration for a release
from certain contractual obligations, primarily ongoing lease obligations. The
tax write-off represents a deferred tax asset that will not be realized as a
result of exiting this business. The inventory provision results from exiting
and reengineering certain product lines. Unaudited revenues and operating
losses, excluding restructuring and related costs, of the power electronics and
test equipment business were $12.8 million and $0.9 million, respectively, for
the first six months of 1999 and $37.9 million and $0.2 million, respectively,
for 1998. Thermedics recorded other nonrecurring costs of $0.1 million to write
off a receivable as a result of an unfavorable resolution of a post-closing
adjustment in connection with the sale of a business in 1998.

Thermo Instrument Systems Inc.

      In connection with restructuring actions commenced in 1998, certain
subsidiaries of Thermo Instrument recorded restructuring costs of $0.2 million
and $1.2 million during the second and first quarter of 1999, respectively. The
restructuring costs were primarily for business relocation and facility-closure
costs. Thermo Instrument expects to incur additional restructuring costs
totaling $0.8 million in the third quarter of 1999.

      During the second quarter of 1999, Thermo Instrument recorded other
nonrecurring charges of $13.1 million, including $11.1 million in charges
relating to its equity investment in FLIR (Note 6). These charges were recorded
to equity in loss of unconsolidated subsidiaries, a component of other expense,
net in the accompanying statement of operations. Thermo Instrument's
nonrecurring charges also include an adjustment to cost of revenues of $2.0
million relating to the sale of inventories at Spectra-Physics revalued at the
date of its acquisition. Thermo Instrument recorded a charge of $4.6 million
relating to the sale of such inventories in the first quarter of 1999.

Biomedical and Emerging Technologies

ThermoTrex Corporation

      During the second quarter of 1999, ThermoTrex announced restructuring
actions at its Trex Medical Corporation and ThermoLase Corporation subsidiaries.
In connection with these actions, ThermoTrex recorded restructuring and related
costs of $93.9 million in the second quarter of fiscal 1999, including
restructuring costs of $72.3 million, inventory and warranty provisions of $14.3
million, provisions for uncollectible accounts receivable of $1.6 million, and
other nonoperating charges of $5.7 million.

      During the second quarter of 1999, Trex Medical recorded $18.1 million of
restructuring and related costs, including restructuring costs of $6.1 million
and inventory and warranty provisions of $12.0 million. The restructuring costs
were incurred primarily in connection with the consolidation of certain
facilities and, to a lesser extent, actions to reduce costs in other operations.
Restructuring costs include $2.3 million for facility-closing costs, net of
assumed sublease income; $2.0 million to write off leasehold improvements at
facilities to be closed and to write down fixed assets to their estimated
disposal value; and $1.9 million for severance for 265 employees across all
functions.

      In August 1999, Trex Medical received notification from the FDA denying
its 501(k) filing for its digital mammography system. Trex Medical plans to meet
with the FDA to discuss the reasons for the denial, and expects to implement
various design changes, initiate additional clinical trials, and, if appropriate
after completing such clinical trials, submit a new application for marketing
clearance. Trex Medical hopes to have initiated additional clinical trials
within one year, but there can be no assurance regarding the timing or results
of such clinical trials, or the submission of a new filing to the FDA for
marketing clearance. Trex Medical recorded costs of $9.4 million to establish
inventory provisions and to terminate purchase commitments for products that
have become obsolete due to planned product

                                       14


7.    Restructuring and Related Costs (continued)

changes or excess as a result of a recent decline in demand. The largest
component of the inventory charge was recorded as a result of the decision by
the FDA to deny Trex Medical's application its digital mammography system and
resulting design changes expected to be made to the system. Provisions resulting
from other planned product and technology changes and decreased demand for
certain other products are also principal components of the inventory charge.
Warranty provisions of $2.6 million were recorded for estimated costs to address
certain product warranty issues, including costs associated with corrective
actions to be taken with respect to certain previously sold mammography

      Trex Medical expects to incur additional restructuring costs totaling
approximately $5.0 million, principally over the next several quarters, which
will be recorded when incurred, such as additional charges for certain employee
and business relocation and related costs. Completion of Trex Medical's
restructuring plan is expected to occur in the first quarter of 2000.

      During 1998, ThermoLase initiated certain restructuring activities,
including the announced closure of three domestic spas and the termination of a
joint venture that operated its spa in France. Two of the domestic spas were
closed during the fourth quarter of 1998. ThermoLase closed the third spa, as
well as two additional spas, in the second quarter of 1999. Also during the
second quarter of 1999, ThermoLase sold its remaining nine day spas, as well as
the stock in its destination spa, The Greenhouse Spa, Inc. In connection with
the sale and closures announced in 1999, as well as other actions, ThermoLase
recorded restructuring and related costs of $67.7 million during the second
quarter of 1999, including restructuring costs of $60.3 million, inventory
provisions of $2.3 million, provisions for uncollectible accounts receivable of
$1.7 million, and an investment write-down of $3.4 million. Restructuring costs
include a $19.9 million loss on the sale of its spa businesses; $17.4 million
for the write-off of leasehold improvements and equipment pertaining to the
hair-removal business; $11.7 million for ongoing lease obligations, net of
assumed sublease income; $10.0 million of estimated costs to terminate certain
other obligations related to the ThermoLase hair-removal business; $0.4 million
for losses on laser purchase commitments; $0.3 million to write down investments
in international joint ventures; and $0.4 million for other related costs. In
addition, restructuring costs include $0.2 million of severance costs for
approximately 14 employees across all functions. The inventory provisions were
for certain branded product lines at ThermoLase's Creative Beauty Innovations,
Inc. subsidiary that have been discontinued, and the investment write-down was
to reduce the carrying value of ThermoLase's investment in a privately held
company to its estimated disposal value. The investment write-down is included
in other expense, net in the accompanying statement of operations. Unaudited
revenues and operating losses, excluding restructuring costs, of the spa
businesses were $6.6 million and $15.5 million, respectively, for the first six
months of 1999, and $9.6 million and $14.6 million, respectively, for 1998.

      ThermoTrex and the Company recorded aggregate restructuring costs of $62.7
million during the second quarter of 1999, representing a write-off of cost in
excess of net assets of acquired companies. Of the total write-off, $59.3
million was to write-off cost in excess of net assets of acquired companies that
arose from repurchases of ThermoLase common stock. This asset has become
impaired as a result of continuing losses at ThermoLase and a decision to exit
its principal business. The balance of the write off was recorded by ThermoTrex
as a result of a decision to hold for sale its Trex Communications Corporation
subsidiary, and represents a reduction in the carrying value of Trex
Communications to the amount of expected proceeds from its sale. In addition,
ThermoTrex provided a reserve of $2.3 million for impairment of a note
receivable from an unaffiliated company. This amount is included in other
expense, net in the accompanying statement of operations.

      In addition, ThermoTrex recorded restructuring and related charges of $3.5
million during the first quarter of 1999, including $1.1 million of
restructuring costs, of which $0.6 million was recorded at Trex Medical. The
total charge also includes inventory provisions of $2.4 million that were
recorded by Trex Medical. The restructuring costs were related to severance for
72 employees across all functions.

7.    Restructuring and Related Costs (continued)

Thermo Coleman Corporation

      Thermo Coleman Corporation recorded restructuring and related costs of
$17.0 million during the second quarter of 1999, principally as a result of a
decision to exit certain businesses through sale or closure. Restructuring costs
include $10.5 million to write off cost in excess of net assets of acquired
companies, $2.3 million for the write down of fixed assets, $3.8 million of
inventory provisions, and a $0.4 million provision for a note receivable. The
charges reduce the carrying values of the businesses to the estimated proceeds
from their sale. Unaudited revenues and operating losses of these businesses
were $16.5 million and $3.9 million, respectively, in the first six months of
1999, and revenues and operating income of $34.5 million and $1.5 million,
respectively, in 1998.

Thermedics Inc.

      During the second quarter of 1999, Thermedics recorded $0.3 million of
other nonrecurring costs relating to the proposed transfer of the Company's
wholly owned Thermo Biomedical group of subsidiaries to Thermedics. In addition,
Thermedics recorded $1.4 million of other nonrecurring costs in the first
quarter of 1999, primarily for investment banking fees that were also associated
with the proposed transfer. Thermedics expects to incur additional nonrecurring
costs totaling approximately $0.7 million, principally through December 1999,
which will be recorded when incurred. These charges also relate to the proposed
transfer.

Other

      The Company recorded restructuring costs of $0.2 million and $0.3 million
in the second and first quarter of 1999, respectively.

Energy and Environment

Thermo Ecotek Corporation

      During the second quarter of 1999, Thermo Ecotek recorded $124.3 million
of restructuring costs and other charges of $2.1 million, as a result of actions
detailed below.

      Following significant investments of resources in attempts to correct
operational problems, in May 1999, Thermo Ecotek made a decision to cease
further efforts and hold for sale or disposal its Gillette, Wyoming, facility.
As a result, Thermo Ecotek recorded a restructuring charge of $68.0 million,
including $63.3 million to write down the plant and related equipment to a
nominal salvage value, $4.4 million for estimated land reclamation costs, and
$0.3 million of other exit costs, primarily abandoned-facility payments. Thermo
Ecotek recorded $1.5 million of minority interest income, representing a
minority partner's share of these charges. Revenues of this facility were
nominal during the period it operated. The facility had unaudited operating
losses, excluding restructuring costs, of $6.2 million in the first six months
of 1999 and $7.6 million in 1998.

      Thermo Ecotek's Delano, California, biomass facilities will reach the end
of the fixed price contract period of their power-sales agreement in September
2000. While Thermo Ecotek's forecasts for periods after that time project
positive cash flows, the facilities would operate at a loss due to depreciation
expense that extends beyond fiscal 2000. In May 1999, Thermo Ecotek entered into
an agreement to terminate the power-sales agreement for its Delano facilities,
effective December 31, 1999. The terms of the agreement call for Thermo Ecotek
to receive payments in lieu of operating under its current agreement and is
subject to regulatory approval. Thermo Ecotek recorded a restructuring charge of
$51.0 million as a result of entering into the new agreement, including $47.5
million to write down the plant and related assets to their estimated
recoverable value, $2.4 million related to a loss on the cancellation of the
facility's primary fuel contract, and $1.1 million to write off cost in excess
of net assets of acquired companies.

                                       16


7.    Restructuring and Related Costs (continued)

      Pacific Gas & Electric (PG&E), the customer under a long-term power-sales
agreement at Thermo Ecotek's Woodland, California, plant, has interpreted the
terms of such agreement to permit PG&E to cease payment of fixed contract rates
effective July 1, 1999, and to thereafter purchase power at avoided cost rates.
Although Thermo Ecotek contests this interpretation and is considering its
alternatives concerning this dispute, Thermo Ecotek recorded a restructuring
charge of $3.8 million during the second quarter of 1999, representing
impairment of its net investment in the Woodland facility as a result of PG&E's
decision to cease making payments of fixed contract rates.

      In addition, during the second quarter of 1999, Thermo Ecotek recorded a
charge of $1.5 million to write off a power plant that is held for sale. Thermo
Ecotek believes that the salvage value, if any, is nominal.

      In the second quarter of 1999, Thermo Ecotek also recorded a charge of
$2.1 million representing the write-down of available-for-sale investments
representing an equity interest of its minority partner in the Gillette,
Wyoming, facility due to impairment that Thermo Ecotek deems permanent based on
recent stock prices. This amount is included in loss on investments, net, a
component of other expense, net in the accompanying statement of operations.

Thermo TerraTech Inc.

      In May 1999, Thermo TerraTech announced that its majority-owned
subsidiaries plan to sell several businesses. The businesses proposed to be sold
include the used-oil processing operation of Thermo EuroTech, N.V.; three
soil-recycling facilities of ThermoRetec Corporation, in addition to the sites
previously announced; and the Randers division, BAC Killam Inc., and E3-Killam
Inc. businesses of The Randers Killam Group Inc. In connection with these
actions, Thermo TerraTech recorded $55.9 million of restructuring and related
costs, including restructuring costs of $54.2 million, a tax asset write-off of
$1.1 million, and an inventory provision of $0.7 million. Restructuring costs
include $22.2 million to write down cost in excess of net assets of acquired
companies to reduce the carrying value of the businesses proposed to be sold to
the estimated proceeds from their sale; $20.2 million to write down fixed assets
to their estimated disposal value; $4.6 million for ongoing lease costs for
facilities that will be exited in connection with the sale of certain
businesses; $2.5 million for estimated land reclamation costs; $1.9 million to
write off the cumulative foreign translation adjustment related to Thermo
EuroTech's used-oil processing business; $1.8 million to write off intangible
assets related to license acquisition costs at the used-oil processing business;
$0.6 million for severance costs for 42 employees across all functions; and $0.4
million to write off other current assets associated with the businesses. The
tax asset write-off represents a deferred tax asset that will not be realized as
a result of selling Thermo EuroTech's used-oil processing business. The
inventory provision also relates to exiting this business. The write-down of
fixed assets principally relates to special purpose equipment in the used-oil
processing and soil-recycling businesses. In connection with the actions
discussed above, the Company also recorded $1.7 million to write down cost in
excess of net assets of acquired companies that arose in connection with the
Company's repurchases of Thermo EuroTech common stock. The write off is a result
of continuing losses and a decision to exit Thermo EuroTech's principal
business. Thermo TerraTech expects to incur additional restructuring costs of
approximately $3 million through the first half of 2000, for costs that will be
recorded when incurred, such as additional severance, employee retention, and
relocation expenses.

      The businesses that are proposed to be sold reported aggregate unaudited
revenues and operating income, excluding restructuring and related costs, of
$22.3 million and $0.8 million, respectively, in the first six months of 1999
and aggregate unaudited revenues and operating losses of $54.3 million and $1.1
million, respectively, in 1998.

      During 1998, Thermo TerraTech recorded restructuring costs, primarily
related to the closure or sale of two soil-recycling facilities by ThermoRetec.
ThermoRetec closed one soil-recycling facility in March 1999 and is actively
seeking a buyer for the second soil-recycling facility. If no buyer is found,
ThermoRetec will close the facility.


                                       17


7.    Restructuring and Related Costs (continued)

Thermo Power Corporation

      Thermo Power undertook certain restructuring actions during the second
quarter of 1999, which included a decision to divest its ThermoLyte Corporation
subsidiary, as well as a decision to outsource certain manufacturing and
warranty functions and reduce staffing levels at certain other subsidiaries. In
addition, Thermo Power wrote down certain assets at its Peek sales and service
subsidiaries located in Malaysia and Croatia that have become impaired due to
business conditions in those regions. In connection with these actions, Thermo
Power recorded restructuring and related costs of $12.6 million, including $8.9
million of restructuring costs, inventory provisions of $3.0 million, costs for
outsourcing certain warranty repairs of $0.5 million, and a provision for
uncollectible accounts receivable of $0.2 million. Restructuring costs include
$4.1 million for the write-off of cost in excess of net assets of acquired
companies, of which $2.9 million was to reduce the carrying value of ThermoLyte
to the estimated proceeds from its sale and $1.2 million was to reduce the
carrying value of Thermo Power's investment in its Peek subsidiaries located in
Malaysia and Croatia due to projected undiscounted cash flows from their
operations being insufficient to recover its investment. In addition,
restructuring costs include $2.0 million of severance costs for approximately 63
employees across all functions; $1.6 million for the write-down of certain fixed
assets, principally at operations being exited; and $1.2 million for lease costs
at facilities being abandoned. Inventory provisions represent a write-down of
inventories to estimated salvage value and consist of $1.9 million for raw
materials for product lines being outsourced, $1.0 million for a discontinued
product line, and $0.1 million for inventories at Peek's subsidiaries located in
Malaysia and Croatia. Unaudited revenues and operating losses for ThermoLyte,
excluding restructuring and related costs, were $7.0 million and $1.1 million,
respectively, in the first six months of fiscal 1999, and $5.8 million and $1.0
million, respectively, in 1998.

      Thermo Power recorded restructuring costs of $0.7 million during the first
quarter of 1999 related to actions taken at its Peek subsidiary. The
restructuring costs consisted of $0.4 million of severance costs for
approximately 70 employees across all functions, $0.2 million for lease costs at
facilities being abandoned in connection with the consolidation of facilities,
and an asset write-down of $0.1 million related to the consolidation of such
facilities.

      Thermo Power expects to incur additional restructuring costs totaling
approximately $2.5 million through December 1999 for costs that will be recorded
when incurred, such as additional severance costs and fees associated with
outsourcing certain product lines. Completion of Thermo Power's restructuring
plans is expected to occur by December 1999.

Recycling and Resource Recovery

Thermo Fibertek Inc.

      Thermo Fibertek recorded $2.3 million of restructuring costs during the
first quarter of 1999, consisting of $1.3 million for severance costs for 24
employees across all functions, and $1.0 million to terminate distributor
agreements. In addition, Thermo Fibertek recorded other nonrecurring income, net
of $10.0 million, consisting of an $11.1 million gain on the sale of its Thermo
Wisconsin, Inc. subsidiary and $1.1 million of nonrecurring costs. The
nonrecurring costs consist of $0.5 million for the expected settlement of a
legal dispute, $0.3 million for the impairment of a building held for disposal,
and $0.3 million of other nonrecurring costs. Unaudited revenues and operating
income for Thermo Wisconsin were $1.8 million and $0.4 million, respectively, in
the first quarter of 1999, and $18.9 million and $2.6 million, respectively, in
1998.

                                       18


7.    Restructuring and Related Costs (continued)

Other

      In May 1999, a jury in the superior court of the state of Rhode Island
rendered a verdict against the Company in connection with an installation in
1985 of a wastewater treatment system by a subsidiary of the Company. The
plaintiff has submitted a brief to the court that sets forth a computation of
interest on the damages that, if approved by the court, would bring the total
amount of the award to approximately $21 million. The Company believes that both
the verdict and the interest computation are in error and intends to appeal. Due
to the inherent uncertainty of the appeal process, however, the Company has
recorded a charge of $21 million for this matter in the second quarter of 1999.

      During the second quarter of 1999, the Company also decided to hold for
sale its Peter Brotherhood, Ltd. subsidiary. The Company recorded an $8.4
million write-down of fixed assets to reduce the carrying value of the business
unit to the estimated proceeds from its sale. Unaudited revenues and operating
income for Peter Brotherhood, excluding restructuring costs, were $22.9 million
and $0.9 million, respectively, in the first six months of 1999, and $41.7
million and $1.3 million, respectively, in 1998.

Corporate

      During the second quarter of 1999, the Company recorded $3.6 million of
other nonoperating charges to write down available-for-sale investments due to
impairment that the Company deems permanent based upon recent market prices.
These charges are included in loss on investments, net, a component of other
expense, net in the accompanying statement of operations.

General

      During 1998, certain subsidiaries announced restructuring actions that
included plans for termination of 792 employees. As of January 2, 1999, the
subsidiaries had terminated 550 employees. The restructuring actions in 1999
included plans for the termination of an additional 579 employees. During the
first six months of 1999, 373 employees were terminated in connection with the
restructuring plans announced in 1998 and 1999. A summary of the changes in
accrued restructuring costs, included in other accrued expenses in the
accompanying balance sheet, follows:

(a) Includes provisions in 1999 of $12.8 million for costs to terminate
contracts and $6.9 million for land reclamation costs.

8.    Proposed Reorganization

      During 1998, the Company announced a proposed reorganization, which was
amended in May 1999, involving the Company and certain of its subsidiaries. The
goals of the proposed reorganization include consolidating and strategically
realigning certain businesses to enhance their competitive market positions and
increasing liquidity in the public markets by providing larger market floats for
the Company's publicly traded subsidiaries.

                                       19


8.    Proposed Reorganization(continued)

      The Company plans to combine its wholly owned Thermo Biomedical group of
subsidiaries with Thermedics. The Company would transfer the Thermo Biomedical
group of subsidiaries to Thermedics. Thermedics Detection Inc. and Thermo
Sentron Inc. would be taken private. The public shareholders of Thermedics
Detection and Thermo Sentron would receive cash in exchange for their shares of
common stock of the respective companies. In addition, Thermedics' equity
interest in Thermo Sentron, Thermedics Detection, and Thermo Voltek Corp. would
be transferred to the Company and as a result each of Thermo Sentron, Thermedics
Detection, and Thermo Voltek would become wholly owned subsidiaries of the
Company. In March 1999, Thermedics acquired, through a merger, all of the
outstanding shares of Thermo Voltek common stock that Thermedics and the Company
did not already own. Subsequent to this transaction, Thermedics and the Company
owned approximately 97% and 3%, respectively, of the outstanding common stock of
Thermo Voltek, which ceased to be publicly traded.

      In May 1999, Thermo Power entered into a definitive agreement and plan of
merger with the Company pursuant to which the Company would acquire, for $12.00
per share, all of the outstanding shares of common stock of Thermo Power not
already owned by the Company. Following the merger, Thermo Power's common stock
would cease to be publicly traded. This merger is expected to be completed in
the fourth quarter of calendar 1999.

      In May 1999, ThermoSpectra Corporation entered into a definitive agreement
and plan of merger with Thermo Instrument pursuant to which Thermo Instrument
would acquire, for $16.00 per share, all of the outstanding shares of common
stock of ThermoSpectra not already owned by Thermo Instrument or the Company. In
July 1999, Thermo Vision Corporation entered into a definitive agreement and
plan of merger with Thermo Instrument pursuant to which Thermo Instrument would
acquire, for $7.00 per share, all of the outstanding shares of Thermo Vision not
already owned by Thermo Instrument or the Company. Following the mergers,
ThermoSpectra's and Thermo Vision's common stock would cease to be publicly
traded. Both of these mergers are expected to be completed in the fourth quarter
of 1999.

      Thermo TerraTech, ThermoRetec, The Randers Killam Group, ThermoTrex,
ThermoLase, and Thermo Ecotek would merge into the Company. Shareholders of each
of these companies would receive shares of common stock of the Company in
exchange for their shares of common stock of the respective companies.

      The completion of the merger of Thermo Voltek into Thermedics reduced the
number of the Company's majority-owned subsidiaries to 23. If the reorganization
plan is completed as proposed, it would further reduce the number of the
Company's majority-owned subsidiaries from 23 to 12. Each component of the
reorganization is subject to numerous conditions, including the following (not
all of which are applicable to each component): establishment of prices and/or
exchange ratios; confirmation of anticipated tax consequences; approval by the
boards of directors (including the outside directors) of each of the affected
majority-owned subsidiaries; negotiation and execution of definitive purchase
and sale or merger agreements; completion of review by the Securities and
Exchange Commission of any necessary documents regarding the proposed
transactions; and fairness opinions from one or more investment banking firms on
certain financial aspects of the transactions. One or more of the transactions
may not occur if the applicable conditions previously described are not
satisfied.

Results of Operations

Second Quarter 1999 Compared With Second Quarter 1998

      Sales in the second quarter of 1999 were $1.09 billion, an increase of
$144.5 million, or 15%, over the second quarter of 1998. Excluding restructuring
and other nonrecurring costs, net of $391.3 million and $4.1 million in 1999 and
1998, respectively, described below, and inventory and other provisions of $27.6
million in 1999, segment income decreased to $91.7 million in 1999 from $117.1
million in 1998. (Segment income is income before corporate general and
administrative expenses, other income and expense, minority interest, income
taxes, and extraordinary item.) Operating loss, which includes restructuring and
other nonrecurring costs, net and inventory and other provisions, was $336.1
million in 1999, compared with operating income of $105.5 million in 1998.

Measurement and Detection

      Sales from the Measurement and Detection segment increased $136.8 million,
or 30%, to $588.5 million in 1999. Sales increased due to acquisitions made by
Thermo Instrument Systems Inc. and Thermo Sentron Inc., which added $159.4
million of revenues in 1999. The unfavorable effects of currency translation,
due to the strengthening of the U.S. dollar relative to foreign currencies in
countries in which the Measurement and Detection segment operates, decreased
revenues by $4.2 million in 1999. Revenues from Thermo Instrument's analytical
products, excluding the effects of acquisitions and currency translation,
increased $10.8 million, primarily due to the introduction of new products and
an increase in revenues from sales to customers in Asia due to improved economic
conditions there. In addition, sales of life sciences products, excluding
acquisitions and currency translation, increased $3.3 million due to higher
demand and expansion of sales and distribution channels into new markets. The
increases in revenues from acquisitions and at certain existing businesses were
offset in part by lower revenues from other businesses. Revenues from Thermo
Instrument's industrial products, excluding the effects of acquisitions and
currency translation, decreased $13.1 million, primarily due to lower revenues
at ThermoSpectra Corporation's existing businesses as a result of continued
weakness in the semiconductor industry. Revenues from Thermo Instrument's
process control products, excluding acquisitions and currency translation,
decreased $11.2 million as a result of a reduction in discretionary capital
spending by companies in the process control industry due to difficult market
conditions and, to a lesser extent, a reduction in spending by raw materials
producers. Revenues from this segment's quality assurance and safety products
business decreased $5.8 million due to lower demand. Revenues from this
segment's power electronics and test equipment business decreased $4.2 million
due to lower demand and the sale of a business unit which had sales of $1.6
million in the prior period. There can be no assurance that the trends that have
adversely affected this segment will not continue.

      Segment income margin (segment income margin is segment income as a
percentage of sales), excluding restructuring and other nonrecurring costs of
$30.4 million in 1999 and $1.4 million in 1998, decreased to 10.1% in 1999 from
14.9% in 1998. Excluding charges for the sale of inventories revalued at the
date of acquisition of $2.0 million and other inventory provisions of $0.9
million, segment income margin was 10.6% in 1999. Segment income margin
decreased primarily due to the effect of lower revenues at certain business
units and, to a lesser extent, the inclusion of lower-margin revenues from
Spectra-Physics AB, which was acquired in February 1999. This segment recorded
restructuring and other nonrecurring costs of $30.4 million in 1999 (Note 7),
principally as a result of a decision to hold for sale its power electronics and
test equipment business. The charge primarily represents a reduction in the
carrying value of this business to the expected proceeds from its sale. Thermo
Instrument expects to incur restructuring costs totaling approximately $0.8
million in the third quarter of 1999. In 1998, Thermo Instrument recorded $1.4
million of nonrecurring costs relating to the resolution of an arbitration
proceeding.

Second Quarter 1999 Compared With Second Quarter 1998 (continued)

Biomedical and Emerging Technologies

      Sales from the Biomedical and Emerging Technologies segment were $242.9
million in 1999, an increase of $14.6 million, or 6%, over the 1998 period.
Sales increased primarily due to the inclusion of $16.6 million of sales from
acquired businesses. In addition, sales at Thermo Cardiosystems Inc. increased
$4.1 million, or 25%, while sales of respiratory and monitoring products by the
Company's wholly owned Thermo Biomedical group increased $2.8 million due to
higher demand. In addition, revenues at Thermo Digital Technologies L.L.C.
increased due to continued shipments of digital passport printers under a
contract with the U.S. government that commenced in the third quarter of 1998.
These revenue increases were offset in part by lower revenues at Trex Medical
Corporation. Revenues at Trex Medical, excluding revenues from an acquired
business, decreased $13.1 million. Of this amount, $10.6 million resulted from
the termination of an original equipment manufacturer (OEM) contract with a
major customer following the customer's acquisition by another corporation. In
addition, Trex Medical had lower sales of general-purpose X-ray and
radiographic/fluoroscopic systems, offset in part by higher demand for
mammography systems and related upgrade components.

      Segment loss, excluding restructuring and other nonrecurring costs of
$142.3 million in 1999 and $2.7 million in 1998, was $14.8 million in 1999,
compared with segment income of $20.0 million in 1998. This decline resulted
primarily from inventory and other provisions at several business units which
aggregated $20.2 million in 1999 (Note 7). Excluding these provisions, segment
income for the Biomedical and Emerging Technologies segment was $5.4 million in
1999. Trex Medical had a segment loss, excluding restructuring costs and other
provisions, of $1.5 million in 1999, compared with segment income of $9.6
million in the 1998 period. The decrease in profitability at Trex Medical was
primarily due to a large decrease in sales at existing businesses. The segment
loss at ThermoLase Corporation, excluding restructuring and nonrecurring costs
and other provisions, totaled $7.3 million in 1999, compared with $6.0 million
in 1998. ThermoLase sold The Greenhouse Spa, Inc., and nine of its day spas in
June 1999, and closed its remaining spas as a result of a decision to exit this
business. Thermo Coleman Corporation had a segment loss, excluding restructuring
costs and other provisions, of $2.3 million in 1999, compared with segment
income of $1.3 million in 1998. The segment loss resulted from losses at its
Thermo Information Solutions Inc.'s Internet services subsidiary and at its
Metric Vision subsidiary which commenced operations in the past year.

      Restructuring and other nonrecurring costs of $142.3 million in 1999 (Note
7) includes $60.3 million of costs recorded by ThermoLase in connection with the
sale of its spas and exiting its hair-removal business; $59.3 million to
write-off cost in excess of net assets of acquired companies arising from
repurchases of ThermoLase stock; $12.7 million at Thermo Coleman and $3.4
million at ThermoTrex for the write-off of cost in excess of net assets of
acquired companies and fixed assets to reduce the carrying value of three
businesses to the estimated proceeds from their sale; $6.1 million at Trex
Medical for severance and abandoned leases resulting principally from the
consolidation of facilities; $0.3 million of nonrecurring costs at Thermedics
associated with the proposed transfer of the Company's wholly owned Thermo
Biomedical group of subsidiaries to Thermedics; and $0.2 million of other
severance costs. This segment expects to have additional restructuring costs of
approximately $5.7 million over the remainder of 1999. Restructuring costs of
$2.7 million in 1998 includes $1.9 million recorded by ThermoLase in connection
with certain actions, including the relocation of its headquarters from
California to Texas, and $0.8 million recorded by SensorMedics Corporation in
connection with the reorganization of a subsidiary in the Netherlands.

Energy and Environment

      Sales from the Energy and Environment segment increased $4.1 million to
$196.5 million in 1999. Revenues from Thermo Ecotek Corporation increased $1.5
million in 1999 to $52.3 million. The increase results from the expansion of an
existing power generation facility and two facilities placed in service during
the quarter for the summer peak season. These increases were offset in part by
lower revenues at Thermo Ecotek's Thermo Trilogy Corporation biopesticide
subsidiary due to lower demand. As noted below, the periods during which Thermo
Ecotek receives fixed rates for power at these facilities has ended or will end
in 2000. The change from fixed rates to avoided cost rates under the terms of
the contracts, as discussed below, will have a significant adverse effect on
Thermo

                                       22



Second Quarter 1999 Compared With Second Quarter 1998 (continued)

Ecotek's revenues and profitability. Sales at Thermo Power Corporation increased
$3.4 million in 1999 to $68.3 million, principally due to revenues of $3.1
million from an acquired business and higher demand for gas-fueled cooling
systems and standard industrial refrigeration packages. These increases were
offset in part by a $7.0 million decrease in Thermo Power's revenues as a result
of the sale of its Crusader Engines division in December 1998. Revenues at
Thermo TerraTech Inc. decreased slightly to $75.9 million in 1999 from $76.7
million in 1998.

      Segment income, excluding restructuring costs of $189.2 million in 1999,
was $13.9 million in 1999, compared with $20.6 million in 1998. Excluding
provisions for inventories and other charges of $4.4 million, segment income was
$18.3 million in 1999. Thermo Ecotek's segment income before restructuring costs
in 1999 was $8.8 million in 1999, compared with $10.5 million in 1998. The
decrease resulted principally from a loss of $0.3 million at Thermo Trilogy in
1999, compared with income of $0.9 million in 1998, due to lower revenues.
Segment income at Thermo Power, excluding restructuring costs and other charges
in 1999, was $3.8 million in 1999 and $5.4 million in 1998. The decrease
occurred primarily at Thermo Power's Peek plc subsidiary as a result of a change
in sales mix and higher research and development costs. Segment income before
restructuring costs and other charges in 1999 at Thermo TerraTech increased to
$5.7 million in 1999 from $4.7 million in 1998. The increase at Thermo TerraTech
principally resulted from lower depreciation and amortization as a result of
recording write-offs and writedowns during the second quarter of 1999.

      Restructuring costs of $189.2 million in 1999 (Note 7) include $124.4
million at Thermo Ecotek resulting principally from a decision to close its
coal-beneficiation facility and from impairment of its Delano facility following
an agreement to terminate the power-sales agreement for that facility.
Restructuring costs in 1999 also include $8.9 million at Thermo Power resulting
principally from a decision to hold for sale its ThermoLyte subsidiary,
impairment at two sales and service businesses of its Peek subsidiary that
operate in Malaysia and Croatia, and staff reductions and facility
consolidations at other Peek units. Restructuring costs in 1999 at Thermo
TerraTech totaled $54.2 million and result from decisions to sell several
businesses. The charges at Thermo TerraTech primarily reduce the carrying value
of the businesses to the expected proceeds from their sale. In addition, the
Company recorded $1.7 million of restructuring costs associated with cost in
excess of net assets of acquired companies arising from the Company's
repurchases of Thermo EuroTech stock, which has become impaired due to
continuing losses and a decision to exit its principal business. This segment
expects to incur additional restructuring costs of approximately $5.5 million
over the remainder of 1999.

      The power-sales agreements for Thermo Ecotek's Mendota, Woodland, and
Delano plants in California are so-called standard offer #4 (SO#4) contracts,
which require Pacific Gas & Electric (PG&E), in the case of Mendota and
Woodland, and Southern California Edison (SCE), in the case of the Delano
facilities, to purchase the power output of the projects at fixed rates through
specified periods. Thereafter, the utility will pay a rate based upon the costs
that would have otherwise been incurred by the purchasing utilities in
generating their own electricity or in purchasing it from other sources (avoided
cost). Avoided cost rates are currently substantially lower than the rates
Thermo Ecotek has received under the fixed-rate portions of its contracts and
are expected to remain so for the foreseeable future. PG&E commenced paying for
power purchased from the Mendota and Woodland facilities at avoided cost rates
effective in June and July 1999, respectively, although Thermo Ecotek believes
that this change to avoided cost rates occurred six months earlier than the
power-sales agreements provided. Thermo Ecotek is considering its alternatives
concerning this dispute. Thermo Ecotek expects that at current avoided cost
rates its Mendota plant will operate at substantially reduced operating income
levels or at a loss beginning in the third quarter of 1999 and thereafter.
Further, based on current avoided cost rates, the Woodland plant will operate at
breakeven or nominal operating losses through 2010, primarily as a result of
nonrecourse lease obligations that have been partially funded from the Woodland
plant's past cash flows. Absent sufficient reductions in fuel prices and other
operating costs, Thermo Ecotek will draw down power reserve funds to cover
operating cash shortfalls and then, if such funds are depleted, either
renegotiate its nonrecourse lease for the Woodland plant or forfeit its interest
in the plant. The results of the Woodland facility were approximately breakeven
in 1999 and 1998, as a result of recording as an expense the funding of reserves
required under Woodland's nonrecourse lease agreement to cover expected
shortfalls in lease payments. The power-sales


                                       23


Second Quarter 1999 Compared With Second Quarter 1998 (continued)

agreement with SCE for the Delano facilities calls for fixed contract rates
through September 2000. If the agreement reached in May 1999 to terminate Thermo
Ecotek's power-sales agreements for its Delano facilities receives regulatory
approval, Thermo Ecotek expects that the results of the Delano facilities will
be reduced to breakeven or a nominal loss subsequent to December 1999. Should
the agreement not receive approval, Thermo Ecotek expects that its Delano
facilities will continue to have positive cash flows but will operate at
substantial operating losses beginning in the fourth quarter of 2000. In
calendar 1998, the Mendota and Delano plants' aggregate operating income was
approximately $41.7 million. In anticipation of these expected declines in
revenues and operating income, Thermo Ecotek may explore other options for its
biomass facilities, including disposal or repowering.

Recycling and Resource Recovery

      Sales in the Recycling and Resource Recovery segment decreased to $66.2
million in 1999 from $77.0 million in 1998. Sales from Thermo Fibertek Inc.
decreased $10.0 million to $53.5 million in 1999, primarily due to the February
1999 sale of its Thermo Wisconsin, Inc. subsidiary that resulted in a decrease
in revenues of $5.7 million. Revenues at Thermo Fibertek's existing businesses
also decreased primarily due to lower sales of stock-preparation equipment in
Europe and North America and accessories in North America. These decreases were
offset in part by higher revenues from Thermo Fibergen Inc.'s water- and
fiber-recovery services. The unfavorable effects of currency translation
decreased revenues by $0.4 million in 1999.

      Segment income, excluding restructuring and other nonrecurring costs, of
$29.4 million in 1999, was $5.3 million in 1999, compared with $9.4 million in
1998. Segment income decreased primarily at Thermo Fibertek as a result of a
decrease in revenues. Restructuring costs of $8.4 million were recorded at the
Company's wholly owned Peter Brotherhood subsidiary to write down property and
equipment to reduce the carrying value of this unit to the estimated proceeds
from its sale. In May 1999, a jury in the superior court of the state of Rhode
Island rendered a verdict against the Company in connection with an installation
in 1985 of a wastewater treatment system by the Company's wholly owned Napco
subsidiary. The plaintiff has submitted a brief to the court that sets forth a
computation of interest on the damages that, if approved by the court, would
bring the total amount of the award to approximately $21 million. The Company
believes that both the verdict and the interest computation are in error and
intends to appeal this matter. Due to the inherent uncertainty of the appeal
process, however, the Company has recorded a charge of $21 million for this
matter in 1999.

Gain on Issuance of Stock by Subsidiaries and Minority Interest Expense

      The Company has, from time to time, caused certain subsidiaries to sell
minority interests to investors resulting in several majority-owned, privately
and publicly held subsidiaries. As a result of the sale of stock by subsidiaries
and the issuance of stock by subsidiaries upon conversion of convertible
debentures, the Company recorded gains of $14.6 million in 1998. The Company
recorded minority interest income of $47.5 million in 1999, primarily as a
result of restructuring and other nonrecurring costs at the Company's
majority-owned subsidiaries. Minority interest expense was $16.7 million in
1998. Minority interest expense in 1998 includes $1.9 million related to gains
recorded by the Company's majority-owned subsidiaries as a result of the sale of
stock by their subsidiaries and the issuance of stock by their subsidiaries upon
conversion of convertible debentures.

Income Taxes

      The company's effective tax rate was a benefit of 24% in 1999. Excluding
nontaxable gains from issuance of subsidiary stock, the Company's effective tax
rate was 45% in 1998. The effective tax rates vary from the statutory federal
income tax rate primarily due to state income taxes and nondeductible expenses,
including in 1999, the write-off of cost in excess of net assets of acquired
companies. In addition, in connection with restructuring actions, certain
subsidiaries wrote off deferred tax assets aggregating $2.5 million in 1999
(Note 7).

                                       24


First Six Months 1999 Compared With First Six Months 1998

      Sales in the first six months of 1999 were $2.10 billion, an increase of
$209.8 million, or 11%, over the first six months of 1998. Excluding
restructuring and other nonrecurring costs, net, of $388.3 million and $4.1
million in 1999 and 1998, respectively, described below, and inventory and other
provisions of $34.6 million in 1999, segment income decreased to $174.7 million
in 1999 from $217.9 million in 1998. Operating loss, which includes
restructuring and other nonrecurring costs, net and inventory and other
provisions, was $265.3 million in 1999, compared with operating income of $197.9
million in 1998.

Measurement and Detection

      Sales from the Measurement and Detection segment increased $191.5 million
to $1.11 billion in 1999. Sales increased due to acquisitions made by Thermo
Instrument and Thermo Sentron, which added $259.6 million of revenues in 1999.
The favorable effects of currency translation, due to the decline in value of
the U.S. dollar relative to foreign currencies in countries in which the
Measurement and Detection segment operates, increased revenues by $1.3 million
in 1999. Increases in revenues from acquisitions and currency translation were
offset in part by lower revenues at existing businesses. Revenues from Thermo
Instrument's industrial products, excluding the effects of acquisitions and
currency translation, decreased $30.4 million, primarily due to lower revenues
at ThermoSpectra's existing businesses as a result of continued weakness in the
semiconductor industry. Revenues from Thermo Instrument's process control
products, excluding acquisitions and currency translation, decreased $20.4
million due to the reasons discussed in the results for the second quarter.
Revenues from this segment's quality assurance and safety products business
decreased $9.1 million due to lower demand and revenues at its power electronics
and test equipment business decreased $9.4 million due to lower demand and the
sale of a business unit which had revenues of $2.9 million in the 1998 period.

      Segment income margin, excluding restructuring and other nonrecurring
costs of $31.6 million in 1999 and $1.4 million in 1998, decreased to 10.4% in
1999 from 14.6% in 1998. Excluding a charge for the sale of inventories revalued
at the date of acquisition of $6.7 million and other inventory provisions of
$0.9 million, segment income margin was 11.0% in 1999. The decrease was due to
the reasons discussed in the results for the second quarter. Restructuring and
other nonrecurring costs of $30.2 million in 1999 (Note 7) principally represent
a charge in connection with the planned sale of the segment's power electronics
and test equipment business, discussed in the results for the second quarter. In
connection with restructuring actions commenced in 1998, Thermo Instrument
recorded restructuring costs of $1.4 million in 1999, primarily for business
relocation and facility-closure costs and severance costs (Note 7). In 1998,
Thermo Instrument recorded $1.4 million of nonrecurring costs for the reason
discussed in the results of operations for the second quarter.

Biomedical and Emerging Technologies

      Sales from the Biomedical and Emerging Technologies segment were $479.2
million in 1999, an increase of $27.6 million, or 6%, over the 1998 period.
Sales increased due to the inclusion of $45.9 million of sales from acquired
businesses. Sales at Thermo Cardiosystems increased $7.1 million, or 22%, due to
higher demand. In addition, revenues from government contracts at Thermo Coleman
increased, and revenues at Thermo Digital Technologies increased due to
continued shipments of digital passport printers under a contract with the U.S.
government that commenced in the third quarter of 1998. These increases were
offset in part by lower revenues at Trex Medical and, to a lesser extent, from a
decrease in sales of respiratory products at the Company's wholly owned Thermo
Biomedical group. Revenues at Trex Medical, excluding revenues from an
acquisition, decreased $35.9 million. Of this amount, $21.9 million resulted
from a reduction in revenues due to the termination of an OEM contract with a
major customer following the customer's acquisition by another corporation.
Revenues also decreased at Trex Medical due to the inclusion in the 1998 period
of a $8.8 million cardiac catheterization system sale to a Russian customer. In
addition, Trex Medical had lower sales of general-purpose X-ray and
radiographic/fluoroscopic systems, offset in part by higher demand for
mammography systems and related upgrade components. Revenues at Thermo
Biomedical decreased $4.4 million primarily due to lower international demand
for respiratory products.

                                       25


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

      Segment loss, excluding restructuring and other nonrecurring costs of
$145.1 million in 1999 and $2.7 million in 1998, was $10.0 million in 1999
compared with income of $38.5 million in 1998. This decline resulted primarily
from inventory and other provisions in 1999 at several business units which
aggregated $22.6 million (Note 7). Excluding these provisions, segment income at
the Biomedical and Emerging Technologies segment was $12.6 million in 1999. Trex
Medical had a segment loss, excluding restructuring costs and other provisions,
of $4.6 million in 1999, compared with segment income of $18.5 million in the
1998. The decrease in profitability at Trex Medical was due to the reason
discussed in the results for the second quarter. The segment loss at ThermoLase,
excluding restructuring costs and other provisions, totaled $13.5 million in
1999, compared with $13.9 million in 1998. Thermo Coleman had a segment loss,
excluding restructuring costs and inventory provisions, of $1.0 million in 1999,
compared with segment income of $2.1 million in 1998. The decrease in
profitability was primarily due to losses at its Metric Vision and Thermo
Information Solutions subsidiaries.

      Restructuring and other nonrecurring costs of $145.1 million in 1999 (Note
7) principally includes the amounts described in the results for the second
quarter. In addition, $1.4 million of nonrecurring costs were recorded by
Thermedics in the first six months of 1999. These costs were associated with the
proposed transfer of the Company's wholly owned Thermo Biomedical group of
subsidiaries to Thermedics and primarily represent investment banking fees.
ThermoTrex, including Trex Medical, recorded $1.1 million of severance costs in
the first quarter of 1999 in addition to the further actions described in the
results for the second quarter. The Company also recorded $0.3 million of other
restructuring costs in 1999. Restructuring costs of $2.7 million in 1998
includes $1.9 million recorded by ThermoLase and $0.8 million recorded by
SensorMedics for the reasons discussed in the results of operations for the
second quarter.

Energy and Environment

      Sales from the Energy and Environment segment were $380.7 million in 1999,
compared with $379.4 million in 1998. Revenues from Thermo Ecotek increased $1.6
million to $99.6 million in 1999. Thermo Ecotek's revenues changed for the
reasons discussed in the results of operations for the second quarter. Sales at
Thermo Power decreased $4.0 million to $129.5 million in 1999, principally due
to the sale of its Crusader Engines division in December 1998. Sales at Crusader
totaled $14.1 million in the first six months of 1998 and its results were
approximately breakeven. This decrease was offset in part by revenues of $6.8
million from an acquired business and higher demand for gas-fueled cooling
systems and standard industrial refrigeration packages. Revenues at Thermo
TerraTech increased $3.8 million to $151.7 million in 1999. Revenues from Thermo
TerraTech's environmental-liability management services increased $1.6 million
due to higher demand at certain business units and, to a lesser extent, the
inclusion of $0.7 million of sales from an acquired business. Revenues from
Thermo TerraTech's engineering and design services increased $1.8 million in
1999 due to an increase in demand for its laboratory services.

      Segment income, excluding restructuring costs of $189.9 million in 1999,
was $23.2 million in 1999, compared with $28.2 million in 1998. Excluding
provisions for inventories and other charges, segment income was $27.6 million
in 1999. Thermo Ecotek's segment income before restructuring costs was $12.6
million in 1999, compared with $16.9 million in 1998. The change resulted from
$3.8 million of higher losses in the 1999 period from Thermo Ecotek's
coal-beneficiation facility which was closed in May 1999 and reduced
profitability at Thermo Trilogy due to lower revenues. Segment income at Thermo
Power, excluding restructuring costs and other charges in 1999, was $5.0 million
in 1999 and $6.7 million in 1998. Segment income decreased for the reasons
discussed in the second quarter, offset in part by the inclusion of income from
an acquisition. Segment income excluding restructuring costs and other charges
at Thermo TerraTech increased to $10.0 million in 1999 from $4.8 million in
1998. Segment income increased principally due to a loss of $5.4 million in 1998
at one of ThermoRetec's business units as a result of losses on certain
remedial-construction contracts. Restructuring costs of $124.4 million at Thermo
Ecotek, $54.2 million at Thermo TerraTech, and $1.7 million relating to the
Company's repurchases of Thermo EuroTech stock, are described in the results for
the second quarter. Restructuring costs of $9.6 million were recorded by Thermo
Power in 1999, principally for the actions described in the results for the
second quarter (Note 7).

                                       26



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

Recycling and Resource Recovery

      Sales in the Recycling and Resource Recovery segment decreased to $140.5
million in 1999 from $150.3 million in 1998. Sales at Thermo Fibertek decreased
$12.1 million to $113.8 million in 1999, primarily due to the February 1999 sale
of its Thermo Wisconsin subsidiary that resulted in a decrease in revenues of
$9.7 million. Lower revenues from stock-preparation equipment and accessories
was offset in part by higher revenues from water- and fiber- recovery services.
Revenues increased by $4.3 million at the Company's wholly owned Peter
Brotherhood subsidiary due principally to a contract to sell turbine generators
to a customer in Russia.

      Segment income, excluding restructuring and other nonrecurring costs, net,
of $21.7 million in 1999, decreased to $12.4 million in 1999 from $17.3 million
in 1998. The decrease was primarily due to lower segment income at Thermo
Fibertek as a result of lower revenues and the sale of Thermo Wisconsin which
represented $1.2 million of the decrease. This decrease was offset in part by an
increase in segment income at Peter Brotherhood due to higher revenues.
Restructuring and other nonrecurring costs, net of $21.7 million included $21.0
million related to litigation and $8.4 million in connection with the planned
sale of Peter Brotherhood, as described in the results for the second quarter,
offset in part by nonrecurring income of $7.7 million at Thermo Fibertek. The
nonrecurring income at Thermo Fibertek consists of a gain on the sale of Thermo
Wisconsin of $11.1 million, offset in part by restructuring and other
nonrecurring costs of $3.4 million (Note 7).

Gain on Issuance of Stock by Subsidiaries and Minority Interest Expense

      As a result of the sale of stock by subsidiaries and the issuance of stock
upon conversion of convertible debentures, the Company recorded gains of $54.2
million in 1998. The Company recorded minority interest income of $43.4 million
in 1999, primarily as a result of restructuring and other nonrecurring costs at
the Company's majority-owned subsidiaries. Minority interest expense in 1998
includes $14.3 million related to gains recorded by the Company's majority-owned
subsidiaries as a result of the sale of stock by their subsidiaries and the
issuance of stock by their subsidiaries upon conversion of convertible
debentures.

Income Taxes

      The Company's effective tax rate in 1999 was a benefit of 18%. Excluding
nontaxable gains from issuance of subsidiary stock, the Company's effective tax
rate was 45% in 1998. The effective tax rates vary from the statutory federal
income tax rate primarily due to state income taxes and nondeductible expenses,
including in 1999, the write-off of cost in excess of net assets of acquired
companies. In addition, in connection with restructuring actions, certain
subsidiaries wrote off deferred tax assets aggregating $2.5 million in 1999
(Note 7).

Liquidity and Capital Resources

      Consolidated working capital was $1.70 billion at July 3, 1999, compared
with $2.16 billion at January 2, 1999. Included in working capital were cash,
cash equivalents, and short-term available-for-sale investments of $1.07 billion
at July 3, 1999, compared with $1.55 billion at January 2, 1999. In addition,
the Company had $97.4 million of long-term available-for-sale investments at
July 3, 1999, compared with $95.5 million at January 2, 1999. Of the total $1.17
billion of cash, cash equivalents, and short- and long-term available-for-sale
investments at July 3, 1999, $1.09 billion was held by the Company's
majority-owned subsidiaries, and the balance was held by the Company and its
wholly owned subsidiaries.

      Cash provided by operating activities was $90.1 million during the first
six months of 1999. Other current liabilities decreased by $52.9 million,
primarily due to a reduction in accrued taxes as a result of a tax benefit
recorded on the Company's pretax loss in 1999, as well as the timing of tax
payments. Cash of $11.8 million was used to fund

                                       27


Liquidity and Capital Resources (continued)

an increase in inventories, principally relating to analytical products at
Thermo Instrument due to the build-up of inventory in preparation for new
product releases and the timing of shipments. In addition, cash of $7.0 million
was used to fund an increase in accounts receivable, principally at Thermo
Ecotek due to increased activity at its natural gas business and at Thermo Power
due to the timing of shipments. These increases in accounts receivable were
offset by a reduction at Thermo Instrument primarily as a result of lower
revenues from analytical products in the second quarter of 1999 compared with
the fourth quarter of 1998.

      During the first six months of 1999, the Company's primary investing
activities, excluding available-for-sale investments activity, included
acquisitions and the purchase of property, plant, and equipment. The Company
expended $345.2 million, net of cash acquired, for acquisitions and expended
$64.2 million for purchases of property, plant, and equipment. In addition,
Thermedics acquired all of the outstanding shares of Thermo Voltek common stock
that Thermedics and the Company did not already own, in completion of its merger
agreement, for $20.5 million of cash.

      The Company's financing activities used $167.0 million of cash during the
first six months of 1999. During the first six months of 1999, the Company
expended $10.5 million to purchase shares of its common stock and the Company
and certain of its majority-owned subsidiaries expended $129.9 million to
purchase shares of common stock and debentures of certain of the Company's
majority-owned subsidiaries. These purchases were made pursuant to
authorizations by the Company's and certain majority-owned subsidiaries' Boards
of Directors. As of July 3, 1999, $111.9 million remained under the Company's
authorization, and $36.9 million remained under authorizations of the Company's
majority-owned subsidiaries. In addition, the Company used $17.1 million of cash
for the redemption of redeemable subsidiary common stock.

      The Company has, from time to time, sold put options for shares of its
common stock to an institutional counterparty. As of July 3, 1999, the Company
had a maximum potential obligation under such arrangements to purchase 5,701,000
shares of its common stock for an aggregate of $83.0 million. The put options
are exercisable only at maturity, expire between November 1999 and May 2000, and
have a weighted average exercise price per share of $14.56. The Company has the
right to settle the put options by physical settlement of the options or by net
share settlement using shares of the Company's common stock.

      In August 1999, Thermo Instrument called for redemption on September 3,
1999, all of the outstanding $14.5 million principal amount of its 3 3/4% senior
convertible debentures due 2000. The value of the securities into which the
debentures are convertible exceeded the redemption amount as of the notice date
of the redemption.

      In connection with certain restructuring actions undertaken by the Company
and its subsidiaries during 1999, the Company expects to incur cash expenditures
of approximately $35 million during the remainder of 1999 and $53 million during
2000. The Company believes that the expected proceeds from businesses to be sold
in connection with certain restructuring actions will exceed the aggregate
estimated cash expenditures for restructuring actions and planned repurchases of
subsidiary common stock in connection with the Company's proposed reorganization
plan (Notes 7 and 8).

      The Company has no material commitments for purchases of property, plant,
and equipment and expects that for the remainder of 1999 such expenditures will
approximate the current level of expenditures. As of August 12, 1999, the
Company's majority-owned subsidiaries acquired new businesses since July 3,
1999, for aggregate cash consideration of $55 million.

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 and certain
discontinued products; (iii) assessing the year 2000 readiness of its key
suppliers and vendors; and (iv) developing contingency plans.

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. The Company's 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 material noncompliant information
technology systems or non-information technology systems that were identified
during phase one are prioritized and remediated. Based on its evaluations, the
Company does not believe that it is required to make any material upgrades or
modifications to its critical non-information technology systems. The Company is
currently upgrading or replacing its material noncompliant information
technology systems, and the majority of this process was complete as of July 3,
1999. The Company expects that all of its material information technology
systems and critical non-information technology systems will be year 2000
compliant by the end of October 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, may not be year 2000 compliant. The Company is continuing to test and/or
evaluate such products. The Company is focusing its efforts on products that are
still under warranty, early in their expected life, subject to FDA
considerations related to the year 2000, and/or pose a safety risk. The Company
is offering upgrades and/or identifying potential solutions where reasonably
practicable.

      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 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 begun to follow up with
significant suppliers and vendors that have not responded 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 the end of
October 1999.

Contingency Plans

      The Company is developing contingency plans that will allow its primary
business operations to continue despite disruptions due to year 2000 problems.
These plans 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,
facilities, products, and significant suppliers and vendors, it will modify and
adjust its contingency plans 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

      The Company had incurred expenses to third parties (external costs)
related to year 2000 issues of approximately $8.0 million as of July 3, 1999,
and the total external costs of year 2000 remediation are expected to be
approximately $14 million. Year 2000 costs are 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 the 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 material
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
compliant, 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
problems 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 described above, if any of
the Company's significant suppliers or vendors experience business disruptions
due to year 2000 issues, there may also be a material adverse effect on the
Company. If any countries in which the Company operates experience significant
year 2000 disruption, the Company could 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 significant 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 interest rates,
foreign currency exchange rates, and equity prices has not changed materially
from its exposure at year-end 1998.
