   Thomas & Betts Corporation Acquires Joslyn Hi-Voltage and Power
            Solutions Businesses from Danaher Corporation

   In a Separate Transaction, Company Also Acquires French Hazardous
               and Emergency Lighting Manufacturer, DTS


    MEMPHIS, Tenn.--(BUSINESS WIRE)--July 2, 2007--Thomas & Betts
Corporation (NYSE:TNB) today announced that it has signed definitive
agreements to acquire the Joslyn Hi-Voltage and Power Solutions
businesses from Danaher Corporation for $280 million and Drilling
Technical Supply SA (DTS), a privately held French manufacturer of
hazardous lighting and electrical controls, for approximately $20
million. Both transactions are expected to be funded from available
cash resources. Subject to the satisfaction of certain customary
closing conditions, the transactions are expected to close in the
third quarter.

    "These acquisitions are an excellent strategic fit for Thomas &
Betts. Joslyn Hi-Voltage products complement our market-leading
portfolio of high-voltage connectors and related products used
primarily by utilities for the distribution of electrical power," said
Dominic J. Pileggi, chairman and chief executive officer. "We are also
very excited to extend our reach into the attractive power quality and
protection markets with the leading brands from Danaher Power
Solutions. The acquisition of DTS expands our already substantial
footprint in critical hazardous and emergency lighting applications.
Overall, these acquisitions broaden our portfolio of leading brands
and allow us to continue to build on our strong relationships with
utility, industrial, OEM and commercial customers."

    Joslyn Hi-Voltage offers a broad range of high voltage electric
switches, reclosers, vacuum interrupter attachments and related
products used mainly by electric utilities. Power Solutions offers a
broad range of products and services designed to ensure a high
quality, reliable flow of power to commercial and industrial customers
for mission critical applications such as datacenters. DTS offers
explosion-proof lighting and electrical protection equipment for a
broad array of industrial markets including drilling, oil and gas,
marine, chemical, pharmaceutical and food products.

    For 2007, management's preliminary assessment is that the
acquisitions will contribute approximately $70 million to revenues and
have a negligible net impact on earnings per share due to the
amortization of acquisition-related intangible assets. For the
calendar year 2008, the company expects the combined acquisitions to
contribute approximately $175 to $185 million in revenues and to be
accretive to earnings per share by approximately $0.10 to $0.15.

    Thomas & Betts Corporation is a leading manufacturing of
electrical components used in construction, industrial and utility
markets. The company is also a leading producer of commercial heating
and ventilation units and highly engineered steel structures used
primarily for utility transmission. Headquartered in Memphis, Tenn.,
the company has manufacturing, distribution and office facilities
worldwide. In 2006, the company reported $1.9 billion in revenues.
