        Greatbatch Announces Acquisition of IntelliSensing LLC

          Strategic Acquisition of Wireless Sensor Technology

    CLARENCE, N.Y.--(BUSINESS WIRE)--Oct. 29, 2007--Greatbatch, Inc.
(NYSE:GB) announced today that its subsidiary, Electrochem Commercial
Power, has acquired substantially all of the assets of IntelliSensing
LLC for approximately $3.9 million in cash. IntelliSensing,
established in 2005 and based in Orchard Park, New York, designs and
manufactures wireless sensor solutions that measure temperature,
pressure, flow and other critical data.

    IntelliSensing's products, powered by lithium batteries, are
designed to operate in environments where wired sensors are
undesirable or impractical. IntelliSensing's portfolio will extend
Electrochem's product portfolio in existing markets to offer complete
technology solutions that enable customers to manage their processes
more effectively, including oil & gas services, military, aerospace
and other industrial applications.

    Unlike many other wireless sensor solutions, IntelliSensing's
products can measure both pressure and temperature all in one, helping
reduce cost for customers by eliminating the need for two separate
sensors. The 'End-to-End' system is based on open standards with
user-defined settings, offering a total turnkey solution for customers
to ensure signal integrity and system interoperability. Proprietary
hardware designs are able to withstand the harsh environments in which
Electrochem customers operate.

    "We are very excited to add IntelliSensing to the Electrochem and
Greatbatch family," said Susan Bratton, Senior Vice President of
Greatbatch Commercial Power. "They are an exceptional organization and
advance our strategic plans to offer more comprehensive technology
solutions into the market. IntelliSensing's exciting array of emerging
products is on the cutting edge of wireless sensor technology, and is
a natural evolutionary next step on our mission to become a total
solution provider to our customers."
