Aearo Reports First Quarter Sales Increase of 20.9%

INDIANAPOLIS,  February 15, 2005 - Aearo Company I (the  "Company"),  one of the
world's  leading  designers,  manufacturers  and  marketers  of a broad range of
personal  protective  products,  today  announced  that net  sales for the three
months  ended  December  31, 2004  increased  20.9% to $95.8  million from $79.2
million in the three months ended  December 31, 2003.  The increase in net sales
was  primarily  driven by organic  growth in the Safety  Products and  Specialty
Composites segments and foreign currency  translation.  The weakness of the U.S.
dollar favorably impacted net sales by $2.8 million.

Grossprofit  for the three months ended  December  31, 2004  increased  25.7% to
$47.1 million from $37.4  million for the three months ended  December 31, 2003.
Gross  profit as a percentage  of net sales for the three months ended  December
31, 2004 was 49.1% as compared to 47.3% for the three months ended  December 31,
2003.  The  improvement  in the gross  profit  percentage  is  primarily  due to
favorable  product  mix,  productivity  improvements  and the  impact of foreign
currency translation.

Operating income for the three months ended December 31, 2004 increased 29.6% to
$11.9  million from $9.1  million for the three months ended  December 31, 2003.
Operating  income  as a  percentage  of net sales  for the  three  months  ended
December  31,  2004  increased  to 12.4% from 11.5% for the three  months  ended
December 30, 2003.

Interest expense, net, for the three months ended December 31, 2004 decreased to
$5.2 million from $5.5 million for the three months ended December 31, 2003. The
decrease is due to lower weighted average interest rates under the Company's new
credit facility and the 8.25% senior subordinated notes, partially offset by the
increase in the level of the Company's debt.

Net income for the three months ended December 31, 2004 increased  73.6% to $5.0
million  from $2.9 million for the three  months  ended  December 31, 2003.  Net
income as a percentage of net sales for the three months ended December 31, 2004
increased to 5.2% from 3.6% for the three months  ended  December 30, 2003.  The
increase in net income is primarily attributed to improvement in sales and gross
profit,  as mentioned above,  combined with controlled  operating  expenses that
declined as a percentage of net sales.

Adjusted  EBITDA,  defined as earnings  before  interest,  taxes,  depreciation,
amortization and other non-cash charges increased 38.8% to $15.8 million for the
three  months  ended  December  31, 2004 from $11.3  million in the three months
ended December 31, 2003. A  reconciliation  of Adjusted  EBITDA to income before
provision for income taxes  determined in accordance with accounting  principals
generally  accepted in the United States of America ("GAAP") is set forth below.
The increase in Adjusted  EBITDA was primarily  driven by organic  growth in the
Safety Products and Specialty  Composites segments,  productivity  improvements,
foreign currency  translation and controlled operating expenses that declined as
a percentage of net sales.

The  Company  uses  Adjusted  EBITDA,  as defined  above,  a non-GAAP  financial
measure,  as a management tool to measure and monitor financial  performance and
as part of the  calculation  of  Company  performance  as stated in senior  bank
facility  covenants.  While the  Company  believes  Adjusted  EBITDA is a useful
indicator  of its  ability  to  service  debt,  Adjusted  EBITDA  should  not be
considered as a substitute for net income (loss)  determined in accordance  with
GAAP as an indicator of operating performance, or as an alternative to cash flow
as a measure of liquidity.  Investors  should be aware that Adjusted  EBITDA may
not be comparable to similarly titled measures  presented by other companies and
comparisons could be misleading unless all companies and analysts calculate this
measure  in the same  fashion.  The  Company  believes  that  the most  directly
comparable  financial  measure to  Adjusted  EBITDA in  accordance  with GAAP is
income  before  provision  for income  taxes.  The  following  table  provides a
reconciliation  of Adjusted  EBITDA to income before  provision for income taxes
for the  three  months  and nine  months  ended  December  31,  2003  and  2004,
respectively:
