ITEM 5.  OTHER EVENTS.

     Complexity Reduction and Restructuring. On September 30, 1998, Aearo
Corporation (the "Company") issued the following press release:

            AEARO CORPORATION ANNOUNCES PLAN TO IMPROVE PROFITABILITY
                 THROUGH COMPLEXITY REDUCTION AND RESTRUCTURING

INDIANAPOLIS--(BUSINESS WIRE)--Sept. 30, 1998--Aearo Corporation today announced
a plan to improve profitability by eliminating certain product offerings in its
Eyewear and Respiratory product lines, reducing headcount in North America
through restructuring and outsourcing, consolidating the branding in its
Consumer product line and reducing selling and manufacturing costs in its
Prescription eyewear product line. The company intends to take a $10 million
restructuring charge in the quarter ended September 30, 1998.

Mike McLain, president and chief executive officer, stated, "This plan will
enable us to improve our profitability in these strategically important product
lines. While we have attractive market positions, our offerings have become too
broad and, as a result, we have a level of complexity that requires higher
costs. By focusing on the key offerings where we have a competitive advantage,
we will be able to improve productivity while, at the same time, offering
superior customer service at acceptable levels of profitability.

"Our restructuring involves four elements: (1) reducing stock-keeping units
(SKUs) and product lines in our Eyewear and Respiratory categories; (2) creating
a more focused and flatter organization by eliminating 60 administrative and
manufacturing overhead positions in North America, as well as outsourcing
certain hand-assembly operations in order to reduce costs; (3) consolidating our
Consumer product offerings under one brand and packaging system with improved
graphics, quality and consistency; and (4) improving the profitability of our
Prescription eyewear business by reducing dispensing costs, centralizing
inventory and investing in a new information technology system to reduce
administrative costs and improve customer service.

We have been pleased with the recovery in profitability that we have experienced
through the first three quarters of this fiscal year. At the same time, there
are portions of our business that are not achieving full potential. We are now
taking the actions necessary to improve profitability further. These moves will
reduce our employment in North America by more than 10 percent."

The restructuring charge is expected to include severance and related costs of
$3 million; consumer packaging, literature and return costs of $1 million;
write-offs of tools and equipment of $1 million; and a write-off of inventory
related to discontinued offerings of $5 million. The cash outlay components of
this charge are expected to total $4 million. The annual benefits are estimated
to total $4.5 million in Fiscal 1999 and $6.5 million in Fiscal 2000.

The company expects to amend its credit agreement with its senior lenders to
avoid any covenant violations that could occur as a result of the restructuring
charge.

Headquartered in Indianapolis, Aearo Corporation had sales of $293 million and
EBITDA of $46 million for the 12 months ended June 30, 1998. The company
designs, manufactures and sells personal protection equipment, including hearing
protection, prescription and non-prescription safety eyewear and respirators.
The company's products, marketed under the E-A-R, AOSafety, Peltor and Eastern
brand names, are sold principally to industrial safety distributors and are used
by industry, government, the military and health providers. Its AOSafety and
Eastern products can be found in retail outlets such as home centers, hardware,
drug and sporting goods stores. In addition, its E-A-R Specialty Composites
division manufactures energy-absorbing materials for the transportation, OEM and
healthcare markets. Aearo operates 10 manufacturing plants throughout the world,
employing more than 1,800 workers.

     B.   Third Amendment to Credit Agreement. On September 30, 1998, the 
Company and its bank group amended the Company's credit facility to provide 
that the above restructuring charge will not give rise to a violation of any
covenants under the credit facility for the period ended September 30, 1998.
