    o BROADENS CAPABILITIES AS A TOP PROVIDER OF DRUG DISCOVERY SOLUTIONS
o ADDS AUTOMATED LIQUID HANDLING, SAMPLE PREPARATION AND BIOCHIP TECHNOLOGIES

BOSTON, MASSACHUSETTS AND MERIDEN, CONNECTICUT... PerkinElmer, Inc. (NYSE: PKI),
a leading provider of life sciences solutions, and Packard BioScience, a global
leader in drug discovery tools, jointly announced today a definitive agreement
for PerkinElmer to acquire Packard BioScience in a deal valued at approximately
$650 million, including net indebtedness. The transaction, which is subject to
customary closing conditions and regulatory approvals, as well as the approval
of the shareholders of both PerkinElmer and Packard BioScience, is expected to
close during the fourth quarter. It is structured as a tax-free, all-stock
merger with an exchange ratio of 0.311 share of PerkinElmer common stock for
each share of Packard BioScience common stock.

 "Packard BioScience represents an excellent strategic fit as a leading supplier
of automated liquid handling, sample preparation tools and advanced biochip
technologies," said Gregory L. Summe, Chairman and CEO of PerkinElmer. "Liquid
handling is a critical, enabling step in both proteomics and genomics workflow,
and increases the productivity of our customers' drug discovery processes.
Packard BioScience's core capabilities in this area, its complementary range of
products, its impressive new product development pipeline, and its
well-respected team of field sales and service experts will enable us to provide
more powerful solutions to our expanding base of life sciences customers."

Packard BioScience, headquartered in Meriden, Connecticut, has approximately
1,000 employees and sales in 60 countries supported through its offices in North
America, Europe and Asia. The company, which expects revenues of approximately
$200 million in 2001, has strategic alliances with a number of the world's
leading bioscience and chip technology companies, including Motorola, Oxford
GlycoSciences and Waters Corporation.

Emery Olcott, Chairman and CEO of Packard BioScience, remarked, "the merger
announced today positions the company to bring together the capabilities we need
to deliver the solutions that our customers demand. Our strength in liquid
handling and automated sample preparation products, combined with PerkinElmer's
instrumentation and reagent depth, will allow us to offer the full spectrum of
drug discovery tools leveraged by a broad and focused worldwide sales, service
and applications capability. The combined company will be well-positioned to
address the emerging biochip and microarray markets with their combined
technologies, including consumables, instrumentation and informatics software.
We feel strongly that this transaction will create real value for our customers,
our associates and our shareholders."
