       Thermo Electron Completes Acquisition of Kendro Laboratory Products


WALTHAM, Mass., May 9, 2005 - Thermo Electron Corporation (NYSE: TMO), the world
leader in analytical instruments, has completed its previously announced
acquisition of Kendro Laboratory Products, a division of SPX Corporation (NYSE:
SPW).

On January 19, 2005, Thermo Electron announced that it had signed a definitive
agreement to acquire Kendro for $833.5 million in cash, subject to a
post-closing balance sheet adjustment. Kendro is a global leader in sample
preparation products and services for life science, material science and drug
discovery applications, with 2004 revenues of approximately $370 million.

"As a company, Thermo is focused on providing total laboratory solutions and
services to address our customers' needs, and Kendro's technologies nicely
complement our existing portfolio of products and services," said Marijn E.
Dekkers, president and chief executive officer of Thermo Electron. "The combined
company allows us to deliver even greater value to our customers by creating a
broader offering of laboratory and sample preparation technologies, as well as
enhanced laboratory service capabilities."

Mr. Dekkers continued, "This transaction underscores our intent to use
acquisitions to gain access to technologies that are of interest to our
customers. It also provides an attractive financial profile for Thermo in terms
of earnings and cash flow generation. When we announced the agreement to acquire
Kendro in January, we said we expected it to be at least $.10 accretive to our
adjusted earnings per share (EPS) in the first full year of ownership and
slightly dilutive to GAAP EPS. We are still confident we can deliver these
results, and we will provide more detailed earnings guidance to reflect the
impact of the Kendro acquisition on May 17, 2005, at our annual shareholders'
meeting and investor conference."

Adjusted EPS excludes restructuring and other costs/income, amortization of
acquisition-related intangible assets, certain other gains/losses, tax
provisions/benefits related to the previous items and benefit from tax
carryforwards.

Use of Non-GAAP Financial Measures
Thermo's guidance as to the expected impact that the acquisition will have on
Thermo's earnings per share is only provided on an adjusted basis. It is not
feasible to provide the expected impact that the acquisition will have on a GAAP
basis because the items excluded are difficult to predict and estimate and are
primarily dependent on future events, such as the determination of the portion
of the purchase price attributable to identifiable intangible assets and the
amortization thereof and decisions concerning the location and timing of
facility consolidations.
