           Thermo Electron Reports Strong Fourth Quarter 2002 Results


WALTHAM, Mass. (February 5, 2003) - Thermo Electron Corporation (NYSE:TMO) today
reported GAAP diluted earnings per share (EPS) of $.51 for the fourth quarter of
2002, compared with a $.04 loss in the year-ago quarter. Fourth quarter revenues
were $569 million in 2002, up 2 percent from $560 million in the same period in
2001. Eliminating favorable currency effects of 4 percent and the impact of
acquisitions and divestitures, organic revenues declined by 2 percent. GAAP
operating margin for the quarter was 6.8 percent in 2002, versus negative 8.7
percent in 2001.

In order for investors to gain a better understanding of our operating results,
we believe it is useful to present our financial results on both a GAAP and
adjusted basis, consistent with how we measure our operating performance. In
this regard, adjusted EPS increased 24 percent to $.31 for the fourth quarter of
2002, versus $.25 in the same period of 2001. Fourth quarter adjusted operating
margin was 12.1 percent in 2002, versus 11.5 percent in the year-ago quarter.

Adjusted EPS and adjusted operating margin (detailed in the accompanying
schedules) exclude inventory charges, primarily for abandoned product lines;
restructuring and other costs/income; amortization of acquisition-related
intangibles; certain other income; gain/loss on disposal of discontinued
operations; extraordinary item; and the cumulative effect of a change in
accounting principle.

For the 12 months ended December 28, 2002, GAAP diluted earnings per share were
$1.73, versus breakeven results in 2001. Adjusted EPS rose 11 percent to $.99 in
2002, up from $.89 in 2001. Revenues declined by 5 percent to $2.09 billion in
2002, from $2.19 billion in 2001. Eliminating favorable currency effects of 1
percent and the impact of acquisitions and divestitures, organic revenues also
declined by 5 percent. GAAP operating margin was 7.5 percent in 2002, versus 1.6
percent in 2001. Adjusted operating margin was 10.8 percent in 2002, versus 11.0
percent in 2001.

"We are pleased to report strong EPS growth in both the quarter and the full
year, despite continued pressure on the top line, as well as solid operating
cash flow of $60 million from continuing operations in the fourth quarter," said
Marijn E. Dekkers, president and chief executive officer of Thermo Electron. "We
continue to experience softness in many of the markets we serve; nevertheless,
our productivity initiatives are contributing directly to bottom-line growth and
we expect this to continue in 2003. Further, we're harnessing the best of what
we have to offer across Thermo in order to serve customers better and more
efficiently. We have innovative new products and services in the pipeline,
unparalleled depth and breadth of capabilities, and we are leveraging our
expertise across the company to offer broader, more integrated solutions to meet
our customers' evolving needs."

Commenting on earnings guidance for the first quarter of 2003 as well as for the
full year, Mr. Dekkers said, "While we're not counting on improvement in the top
line in the near-term given the economic uncertainty, we believe that we are
well positioned to make continued progress on the bottom line. Our goal is to
deliver EPS of $.22 to $.24 for the first quarter of 2003, and $1.07 to $1.12
for the full year, excluding the items detailed above in the description of
adjusted EPS." It is not feasible to provide meaningful GAAP EPS guidance
because many of the items we have excluded are difficult to estimate

                                     -more-


and primarily dependent on future events, such as decisions concerning the
location and timing of facility consolidations, and on market conditions that
affect the timing and proceeds from the sale of our remaining equity interests.



                                 Sector Results


Please Note: Improvement in all three sectors' GAAP results was due in part to
significant restructuring charges in the 2001 period and the absence of goodwill
amortization in the 2002 period due to the adoption in 2002 of SFAS No. 142,
"Goodwill and Other Intangible Assets." See the accompanying schedules for
details. Organic revenue growth figures exclude the effects of acquisitions,
divestitures, and currency translation.

Life and Laboratory Sciences
Fourth quarter 2002 revenues for the Life and Laboratory Sciences sector were
$314 million, versus $305 million in 2001, with organic revenues down 1 percent.
We had strong shipments of chromatography systems, magnetic-sector mass
spectrometry instruments, and laboratory information management systems (LIMS).
These increases were offset by lower sales at our business that provides turnkey
laboratories in emerging economies, which had a particularly strong fourth
quarter in 2001, and continued softness in our laboratory-equipment business.
Productivity initiatives led to significant improvements in both GAAP and
 adjusted operating margins. On a GAAP basis, operating margin was 15.2 percent
in the fourth quarter of 2002, versus 4.6 percent in 2001. Adjusted operating
margin rose 200 basis-points to 19.6 percent for the quarter, up from 17.6
percent in 2001.

We continue to innovate, with new customer-focused products that have been well
received in the marketplace, including the TraceTM DSQ single quadrupole GC/MS
system launched earlier this year, and the Shandon ExcelsiorTM Tissue Processor,
a fully automatic solution for tissue processing and reagent storage and
handling, which features improved processing quality and enhanced safety. We
dedicate significant resources to R&D to ensure we remain on the cutting edge of
technology, and we believe customers will be impressed by the host of new
products we will introduce at Pittcon this March.

Measurement and Control
Fourth quarter 2002 revenues for the Measurement and Control sector were $171
million, versus $155 million in 2001, with organic revenues up 7 percent. We saw
strong demand for our explosives trace detection equipment, driven by the
congressional mandate to screen 100 percent of all checked airline baggage by
the end of the 2002, and modest improvement in sales of process instruments to
food and beverage and pharmaceutical customers - offset by continued weak
general demand in other industrial manufacturing markets. GAAP operating margin
was 6.4 percent for the 2002 quarter, versus a negative 3.4 percent in the
previous year. Adjusted operating margin was 11.1 percent in 2002, up from 10.1
percent in 2001, due to higher revenues and successful productivity and
integration initiatives.

Our July acquisition of Saint-Gobain's radiation-monitoring products business
has exceeded expectations for revenues and earnings. We continue to see strong
sales of our expanded line of radiation-monitoring products used in security
applications to protect public safety at borders, airports, seaports, freight
and shipping facilities, and other public venues.

Optical Technologies
Fourth quarter 2002 revenues for the Optical Technologies sector were $86
million, versus a particularly strong quarter in 2001 of $102 million. The
continued weakness in the worldwide semiconductor market and slow economic
conditions for our industrial customers affected the entire sector, and organic
revenues were down 16 percent. GAAP operating margin was negative 5.0 percent
for the fourth quarter of 2002, versus negative 41.9 percent in 2001. Adjusted
operating margin for the sector was 4.0 percent in the 2002 quarter, compared
with 5.3 percent in 2001.

                                     -more-


We introduced a number of new products in January, including the latest
Spectra-Physics Vanguard laser - an innovative solid-state system that can
replace water-cooled ion lasers and offer lower cost-of-ownership in a wide
range of commercial and biomedical applications. This January, we also combined
all of our lasers and photonics offerings under the Spectra-Physics name to
leverage Spectra-Physics' strong brand value with a broader set of customers.

(a) Reported results were determined in accordance with U.S. generally accepted
accounting principles (GAAP).

(b) Adjusted results exclude inventory charges (note c), amortization of
acquisition-related intangible assets and, in 2001, amortization of goodwill,
restructuring and other costs/income (note d), certain other income/expense
(note e), gain (loss) on disposal of discontinued operations, extraordinary item
(note f), and the cumulative effect of change in accounting principle. The
excluded amortization decreased due to the adoption of SFAS No. 142, effective
in 2002.

(c) Reported results in 2002 include $6,722,000 of inventory writedowns for the
abandonment of product lines and $2,404,000 of charges for the sale of

include $26,095,000 of inventory writedowns, principally for the abandonment of
product lines.

(d) Reported results in 2002 include restructuring and other items consisting
principally of charges for abandoned equipment leases at Spectra-Physics;
severance; abandoned facility and other expenses of real estate consolidation;
cancellation penalties on capital equipment purchases; impairment of abandoned
assets; and legal/advisory fees associated with a reorganization of the
company's non-U.S. subsidiary structure. These items are net of net gains on
the sales of businesses. Reported results in 2001 include restructuring and
other costs consisting principally of severance; abandoned facility and other
expenses of real estate consolidation; charges for asset impairment and lease
obligations on abandoned assets; net losses on sales of businesses; in-process
research and development at an acquired business; and investment banking, legal,
and consulting fees, as well as employee-retention costs associated with the
company's reorganization announced in 2000.

(e) Reported results include $111,432,000 and $35,117,000 of gains from the sale
of shares of FLIR Systems, Inc. in 2002 and 2001, respectively. Reported results
in 2001 include $2,783,000 of impairment of two available-for-sale securities
that were preacquisition assets of acquired businesses.

(f) Extraordinary item represents net gains or losses on early retirement of
debt.

(g) The amounts on a pro forma basis in 2001 to reflect adoption of SFAS No. 142
were as follows: reported basic $.48, reported diluted $.47.

(h) The amounts on a pro forma basis in 2001 to reflect adoption of SFAS No. 142
were as follows: reported basic $.20, reported diluted $.20.

(i) Adjusted earnings per share excludes interest expense on convertible
debentures of $13,198,000 and $266,000, net of tax, in 2002 and 2001,
respectively, for the assumed conversion of such convertible debentures.
