3M to Acquire Aearo Technologies Inc., Global Leader in Personal Protection Equipment

3M and Aearo Technologies Inc. announced today that they have
entered into a definitive agreement for 3M´s acquisition of Aearo for
a total purchase price of $1.2 billion, to be financed through a
combination of cash and other borrowings. Aearo is a global leader in
the personal protection industry and manufactures and markets personal
protection and energy absorbing products. Aearo is owned by funds
advised by Permira, a leading global private equity firm, and company
management.

Aearo will significantly expand 3M´s occupational health and
environmental safety platform by adding hearing protection as well as
eyewear and fall protection product lines to 3M´s existing full-line
of respiratory products. It provides a broad platform for accelerated
growth. This acquisition enables 3M to provide industrial, military
and construction customers as well as consumers with a more complete
personal protection solution.

"Aearo complements and significantly broadens our core safety and
personal protection business, a space which is growing fast and of
strategic importance to the company," said George W. Buckley, 3M
chairman, president and CEO. "The combination of 3M´s technology, our
global reach and well-known safety brand with Aearo´s strong product
portfolio and brands positions 3M as the global leader in personal
protective equipment products. Our powerful international distribution
network will enable us to enhance and leverage this asset going
forward."

Aearo has achieved the leading global market positions in hearing
and eye protection through the strength of its brand names such as
E-A-R, Peltor, AOSafety and SafeWaze, and its reputation for
developing high-quality, innovative products and strong market
competitiveness. The company has demonstrated a strong track record of
consistent market beating growth and profitability, with sales
increasing at a compound annual growth rate of more than 12 percent
over the past five years to $508 million.

The complete Aearo product line includes passive hearing,
communication headsets, eye protection, head and face protection and
fall protection. The company also markets systems solutions and
proprietary energy absorbing materials, which are incorporated into
other manufacturers´ products to control noise, vibration, shock and
temperature.

3M is a recognized leader in personal protective equipment,
providing customers with innovative technologies and solutions that
help increase personal safety and productivity in markets such as
first responder, industrial manufacturing, automotive, shipbuilding,
military, home improvement contractors and consumer.

"Aearo´s knowledgeable and experienced employees, along with its
market-leading products and brands, will broaden our presence in the
large and growing safety market and enable us to increase sales of 3M
products," said Julie L. Bushman, vice president and general manager,
3M Occupational Health & Environmental Safety Division. "Aearo will
benefit from our well established global infrastructure and our
network of professionals within the safety industry."

"We believe 3M´s solid R&D technology platform and global
distribution capabilities will take Aearo´s successful brand to the
next level and grow this business to its full potential," said Michael
McLain, president and CEO, Aearo Technologies Inc. "Our two companies
share a similar culture of innovation and operational excellence, and
the Aearo team is excited about working with 3M colleagues around the
world." Aearo employs approximately 1700 people worldwide.

The acquisition does not change the company´s 2007 earnings per
share guidance as the transaction is not expected to close until the
first quarter of 2008, subject to regulatory approvals and customary
closing conditions. 3M´s financial advisor for the transaction was
Lehman Brothers.

Buckley; Jean Lobey, executive vice president, Safety, Security
and Protection Services; and Patrick D. Campbell, senior vice
president and chief financial officer will conduct an investor
teleconference at 9:00 a.m. Eastern Time (8:00 a.m. Central) today.
