3M to Acquire Aearo Technologies Inc., Global Leader in Personal Protection Equipment
Acquisition Bolsters Ws Personal Protection Franchise
ST. PAUL, Minn. & INDIANAPOLIS--(BUSINESS WIRE)--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 31M 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 complements and
significantly broadens our
core safety and personal
protection business, a
space which is growing
fast and of strategic
importance to the
company"
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.

510-1 EPA NO EXPOSURE CERTIFICATION for Exclusion from
FORM
3510-11 "
NPDES Storm Water Permitting
Submission of this No Exposure Certification constitutes notice that the entity identified in Section A does not require permit authorization for its storm water
discharges associated with industrial activity in the State identified in Section B under EPA's Storm Water Multi -Sector General Permit due to the existence
of a condition of no exposure.
A condition of no exposure exists at an industrial facility when all industrial materials and activities are protected by a storm resistant shelter to prevent
exposure to rain, snow, snowmelt, and/or runoff. Industrial materials or activities include, but are not limited to, material handling equipment or activities,
industrial machinery, raw materials, intermediate products, by-products, final products, or waste products. Material handling activities include the storage,
loading and unloading, transportation, or conveyance of any raw material, intermediate product, final product or waste product. A storm resistant shelter is
not required for the following industrial materials and activities:
— drums, barrels, tanks, and similar containers that are tightly sealed, provided those containers are not deteriorated and do not leak. "Sealed"
means banded or otherwise secured and without operational taps or valves;
— adequately maintained vehicles used in material handling; and
— final products, other than products that would be mobilized in storm water discharges (e.g., rock salt).
A No Exposure Certification must be provided for each facility qualifying for the no exposure exclusion. In addition, the exclusion from NPDES permitting is
available on a facility -wide basis only, not for individual outfalls. If any industrial activities or materials are or will be exposed to precipitation, the facility is

NPDES A% Instructions for the NO EXPOSURE CERTIFICATION for Form Approved
FORM OEMOMB No.2040-0211
3510-11 Exclusion from NPDES Storm Water Permitting
Who May File a No Exposure Certification Section B. FacilitylSite Location Information
Federal law at 40 CFR Part 122,26 prohibits point source discharges of
storm water associated with industrial activity to waters of the U.S, without
a National Pollutant Discharge Elimination System (NPDES) permit. However,
NPDES permit coverage is not required for discharges of storm water
associated with industrial activities identified at 40 CFR 122.26(b)(14)(i)-
(ix) and (xi) if the discharger can certify that a condition of 'no exposure"
exists at the industrial facility or site.
Storm water discharges from construction activities identified in 40 CPR
122.26(b)(14)(x) and (b)(15) are not eligible for the no exposure exclusion.
Obtaining and Maintaining the No Exposure Exclusion
This form is used to certify that a condition of no exposure exists at the
industrial facility or site described herein. This certification is only applicable
in jurisdictions where EPA is the NPDES permitting authority and must be
re -submitted at least once every five years.
The industrial facility operator must maintain a condition of no exposure at
its facility or site in order for the no exposure exclusion to remain applicable.
If conditions change resulting in the exposure of materials and activities to
storm water, the facility operator must obtain coverage under an NPDES
storm water permit immediately.
Where to File the No Exposure Certification Form
Mail the completed no exposure certification form to:
Storm Water No Exposure Certification (4203)
USEPA
401 M Street, SW
Washington, D.C. 20460
Completing the Form
You must type or print, using uppercase letters, in appropriate areas only.
Enter only one character per space (i.e., between the marks). Abbreviate
if necessary to stay within the number of characters allowed for each item.
Use one space for breaks between words. One form must be completed
for each facility or site for which you are seeking to certify a condition of no
exposure. Additional guidance on completing this form can be accessed
through EPA's web site at www.epa.gov/owm/sw. Please make sure you
have addressed all applicable questions and have made a photocopy for
your records before sending the completed form to the above address.
Section A. Facility Operator Information
1. Provide the legal name of the person, firm, public organization, or any
other entity that operates the facility or site described in this certification.
The name of the operator may or may not be the same as the name of
the facility. The operator is the legal entity that controls the facility's
operation, rather than the plant or site manager.
2. Provide the telephone number of the facility operator.
3. Provide the mailing address of the operator (RO. Box numbers may be
used). Include the city, state, and zip code. All correspondence will
be sent to this address.
1. Enter the official or legal name of the facility or site.
2. Enter the complete street address (if no street address exists, provide
a geographic description [e.g., Intersection of Routes 9 and 55]), city,
county, state, and zip code. Do not use a P.O. Box number.
3. Indicate whether the facility is located on Indian Lands.
4. Indicate whether the industrial facility is operated by a department or
agency of the Federal Government (see also Section 313 of the Clean
Water Act).
5. Enter the latitude and longitude of the approximate center of the facility
or site in degrees/minutes/seconds. Latitude and longitude can
be obtained from United States Geological Survey (USGS) quadrangle
or topographic maps, by calling 1-(888) ASK-USGS, or by accessing
EPA's web site at hilp:1lwww.epa.gov/owm/swtindustrylindex.htm and
selecting Latitude and Longitude Finders under the Resources/Permit
section.
Latitude and longitude for a facility in decimal form must be converted
to degrees (°), minutes ('), and seconds (") for proper entry on
the certification form, To convert decimal latitude or longitude to
degreeslminuteslseconds, follow the steps in the following example.
Example: Convert decimal latitude 45,1234567 to degrees (1), minutes
('), and seconds (").
a) The numbers to the left of the decimal point are the degrees: 45°.
b) To obtain minutes, multiply the first four numbers to the right of the
decimal point by 0.006: 1234 x 0.006 = 7.404.
c) The numbers to the left of the decimal point in the result obtained
in (b) are the minutes: 7'.
d) To obtain seconds, multiply the remaining three numbers to the
right of the decimal from the result obtained in (b) by 0.06:
404 x 0.06 = 24.24. Since the numbers to the right of the decimal
point are not used, the result is 24",
e) The conversion for 45.1234567 = 451 7' 24",
6. Indicate whether the facility was previously covered under an NPDES
storm water permit. If so, include the permit number.
7. Enter the 4-digit SIC code which identifies the facility's primary activity,
and second 4-digit SIC code identifying the facility's secondary activity,
if applicable. SIC codes can be obtained from the Standard Industrial
Classification Manual, 1987.
8. Enter the total size of the site associated with industrial activity in acres.
Acreage may be determined by dividing square footage by 43,560, as
demonstrated in the following example.
Example: Convert 54,450 ft2 to acres
Divide 54,450 ft2 by 43,560 square feet per acre:
54,450 ft2 + 43,560 ft2/acre = 1.25 acres.
9. Check "Yes" or "No" as appropriate to indicate whether you have paved
or roofed over a formerly exposed, pervious area (i.e., lawn, meadow,
dirt or gravel road/parking lot) in order to qualify for no exposure. If yes,
also indicate approximately how much area was paved or roofed over
and is now impervious area.
