                 TERADYNE ANNOUNCES AGREEMENT TO ACQUIRE GENRAD

ACQUISITION EXPECTED TO SIGNIFICANTLY EXPAND TERADYNE'S PRESENCE IN CIRCUIT
BOARD TEST AND INSPECTION MARKET

BOSTON--(BUSINESS WIRE)--Aug. 2, 2001--Teradyne, Inc., (NYSE: TER - news) today
announced the signing of a definitive agreement to acquire GenRad, Inc. (NYSE:
GEN - news) of Westford, MA a leading manufacturer of electronic automatic test
equipment and related software.

Under the terms of the proposed acquisition, each outstanding share of GenRad
common stock would be converted into 0.1733 shares of Teradyne common stock. At
Teradyne's closing price of $35.10 on August 1, 2001, the transaction would be
valued at approximately $260 million in the aggregate. This includes the
assumption of debt of approximately $85 million, before considering any proceeds
from the anticipated sale of GenRad's Diagnostic Solutions business unit, which
is expected to occur before the closing with Teradyne. Revenue for the GenRad
business to be retained by Teradyne following the closing of these transactions
was approximately $255 million in 2000.

Robert M. Dutkowsky, chairman, president and CEO of GenRad, Inc. will manage the
combined Teradyne circuit board test and inspection division.

The acquisition of GenRad by Teradyne is expected to close in the fourth quarter
of 2001 and is subject to approval by both the shareholders of GenRad, Inc. and
regulators. The transaction is expected to be slightly dilutive in the fourth
quarter of 2001, with the expectation that it becomes accretive in 2002 when
cost synergies are fully realized and demand picks up.

George W. Chamillard, Teradyne Inc., chairman, president and CEO stated, "The
combination of Teradyne and GenRad broadens our scope in the global electronics
manufacturing test market, creating a 'total test solution' that will
significantly benefit customers."

"Today's electronic products are packing higher speeds and greater functionality
into denser spaces, creating a packaging revolution in electronics
manufacturing," Chamillard said. "This means the electronics product assembly
process has become increasingly complex, placing new demands on test and
inspection equipment--and creating new market growth opportunities. This
complexity also requires sophisticated software tools to optimize and improve
that process. The
   2
addition of GenRad products to our existing product line will give us the
industry's broadest range of circuit board test and inspection products:
in-circuit and functional test systems and automated inspection systems--both
optical and X-ray. Tying it together will be the factory automation software
tools needed to deploy the equipment strategically and manage the process
efficiently."

GenRad's Dutkowsky stated that, "Adding our strengths in electronics testing and
production hardware, software and service solutions to Teradyne's breadth across
the semiconductor, telecommunications, computer and Internet industries is a
superb strategic fit. Our customers will benefit from the expanded capabilities
this new organization will bring to manufacturing test environments worldwide."

Dutkowsky noted that, "Our shareholders will also benefit as new owners of
Teradyne stock because as a global industry leader, Teradyne is ideally
positioned in the marketplace when growth resumes."
