New York, New York - March 11, 2004 - Bear Stearns Merchant Banking, the private
equity arm of Bear,  Stearns & Co. Inc. (NYSE: BSC), has agreed to acquire Aearo

producer of specialty  composite  materials for the transportation and precision

Upon closing of the  acquisition,  expected in early April,  Aearo's  management
team, led by Chairman,  President,  and Chief Executive Officer, Michael McLain,
will make a substantial  capital investment and will own approximately a quarter
of the company's fully diluted common stock,  including options.  Vestar Capital
and its affiliates  intend to retain up to 10% of the company's stock at closing
and will have the  opportunity to invest  additional  equity in the future under
certain circumstances.

"My team and I look  forward to working  with our new  investors at Bear Stearns
Merchant  Banking and are pleased  that our  existing  shareholders  will have a
continued interest in Aearo," McLain commented.  "We plan to focus on our growth
initiatives and on strategic acquisitions that will broaden our product line and
our  channel  presence.  This new  partnership  will  enable us to  continue  to
strengthen our leadership position in the personal protection equipment market."

Indianapolis-based  Aearo has more than 1,500 employees  worldwide.  The company
recorded net sales of $326.9  million for the twelve  months ended  December 31,
2003.

industry and we are pleased and excited to make this  investment,"  said Douglas
Korn, a senior managing director of Bear Stearns Merchant Banking.  "Safety,  in
the workplace, in the home, and in government sectors is increasingly a focus of
employers,  individuals  and  agencies  around  the  world.  We look  forward to
supporting  Aearo's  terrific  management  team as they  pursue  a  strategy  of
continued  growth  through  industry-leading  innovation as well as  synergistic
acquisitions."  Vestar  Managing  Director  Norman W. Alpert  explained that his
private equity firm is confident about the company's prospects.  "Our eight-year
investment in Aearo and partnership with Mike McLain and his team have been very
successful from both a strategic and financial  standpoint,  and we are proud to

protection  equipment market," Alpert said. "We are delighted with the company's
new relationship with Bear Stearns Merchant Banking. Under their stewardship, we
