ITEM 1.  BUSINESS
 
GENERAL
 
Aearo Corporation (formerly Cabot Safety Holdings Corporation), a Delaware
corporation ("Aearo"), and its direct wholly-owned subsidiary, Aearo Company I,
doing business as Aearo Company (formerly Cabot Safety Corporation), a Delaware
corporation (the "Subsidiary"), are collectively referred to herein as the
"Company". The Company is one of the leaders in the hearing, eye, face, head and
respiratory protection segments of the personal protection equipment ("PPE")
market worldwide through its safety products operating unit ("Safety Products"),
which manufactures and sells hearing protection devices, prescription and
non-prescription safety eyewear, face shields, reusable and disposable
respirators, hard hats and first aid kits in more than 85 countries under its
well-known brand names: AOSafety, E-A-R, Eastern and Peltor. Personal protection
equipment encompasses all articles of equipment and clothing worn for the
purpose of protecting against bodily injury, including safety eyewear and
goggles, ear muffs and ear plugs, respirators, hard hats, gloves, safety
clothing and safety shoes. Safety Products accounted for approximately 84% of
the Company's net sales in fiscal 1996. The Company attributes its leading
market positions to:
 
     - Strong, well-recognized brand names
 
     - A reputation for providing innovative, quality products
 
     - Intensive coverage of multiple distribution channels targeting a wide
       array of end-users
 
     - One of the industry's broadest product offerings
 
     - A commitment to providing the highest level of customer service
 
Through its specialty composites operating unit ("Specialty Composites"), the
Company manufactures a wide array of energy-absorbing materials which are
incorporated into other manufacturers' products to control noise, vibration and
shock. Specific product applications for such materials include noise-reducing
and vibration-dampening matting used in the lining of transportation equipment
such as heavy truck cabs, shock protection parts for electronic devices such as
computer disk drives, and durable energy-absorbent and cushioning foams used in
footwear. Specialty Composites also produces specially formulated foam used in
the manufacture of Safety Products' polyvinylchloride ("PVC") ear plugs.
Specialty Composites accounted for approximately 16% of the Company's net sales
in fiscal 1996.
 
Aearo derives all of its operating income and cash flow from the Subsidiary, and
its only material assets are the shares of common stock of the Subsidiary that
Aearo owns. Other than its ownership of the Subsidiary and its guarantee of the
indebtedness of the Subsidiary, Aearo has no business or operations. Aearo was
incorporated in the state of Delaware in June 1995. Detailed information with
respect to the Company's revenue, operating profit, and identifiable assets by
geographic area and amount of export sales is presented in Note 17 of Notes to
Financial Statements of Aearo Corporation contained in Item 8 hereof.
 
PERSONAL PROTECTION EQUIPMENT MARKET
 
A 1996 industry study prepared by Frost & Sullivan estimates the size of the
U.S. segment of the PPE market in which the Company competes (which excludes
safety clothing, gloves and shoes) was approximately $1.0 billion in 1995.
Management estimates annual sales outside the United States for the segment of
the PPE market in which the Company competes were in excess of $1.0 billion in
1995. Historically, a large number of relatively small, independent
manufacturers with limited product lines served the PPE market and the industry
remains highly fragmented.
 
                                        1
<PAGE>   4
 
PRODUCT OVERVIEW
 
The Company operates through two separate operating units: Safety Products and
Specialty Composites.

SAFETY PRODUCTS
 
Within Safety Products, the Company classifies its products in five main
categories: hearing protection; safety prescription eyewear; eye, face and head
protection; first aid kits; and respiratory protection.
 
HEARING PROTECTION.  The Company's hearing protection products primarily consist
of disposable ear plugs, reusable ear plugs, and ear muffs. The Company has been
a leader in hearing conservation research and development since 1972, when it
first introduced the PVC disposable ear plug. Today, this product is known as
the "Classic" and its color yellow is a registered trademark of the Company in
the United States and Canada. This product is designed to be "rolled down" or
compressed before being inserted into the ear, and, as a result of its unique
time delay characteristics, the plug slowly expands (or "recovers") to fill the
ear canal and provide the desired protection. The Company's PVC ear plugs are
available corded and uncorded and in a variety of packaging options. The Company
also produces private label versions of the PVC plug for many of the
international airlines for inclusion in their amenity kits. The Company also
manufactures a full line of polyurethane ear plugs, including its E-Z-Fit and
TaperFit products. These products serve the same disposable ear plug category,
but the PVC ear plugs have historically led the market.
 
In the reusable ear plug segment of the market, the Company offers its patented
UltraFit product and the EAR Caps line of "semi-aural" plugs designed for
intermittent use with easy storage around the neck. Recently, the Company
introduced the E-A-R Express, a patented product, which features a polyurethane
pod and a short plastic stem to facilitate sanitary insertion of the plug in the
ear. The Company also recently introduced the Super-Soft polyurethane ear plug,
and the Ultra-Tech ear plug which provides flat attenuation of sound (noise
reduction without distortion).
 
The Company sells a full range of ear muffs. Through its Peltor AB subsidiary
("Peltor"), acquired on May 30, 1996, the Company manufactures, assembles and
sells a broad line of ear muffs, hard caps/visors, noise attenuation headsets
and wireless and hardwire communication headsets, serving a variety of end user
markets where protection from harmful high and low frequency noise is sought or
the need for easy communication in noisy or remote environment exists, such as
in the construction, heavy machinery, airport, forestry, textile and mining
industries. The Company also offers auditory systems products, which are sold to
audiologists and are used in the testing of hearing.
 
SAFETY PRESCRIPTION EYEWEAR.  The Company's safety prescription eyewear ("SRx")
products are designed to protect the eyes from the typical hazards encountered
in the industrial work environment. The Company purchases component parts
(lenses and the majority of its frames) from various suppliers, grinds and
shapes the lenses to the employee's prescription, and then assembles the glasses
using the employee's choice of frame. The Company views its ability to provide
individual attention to each patient through Company-employed, as well as
independently contracted, eye professionals, as an essential part of its SRx
business.
 
EYE, FACE AND HEAD PROTECTION.  Non-prescription eye and face protection is used
in work environments where a number of hazards present a danger to eyes,
including dust, flying particles, metal fragments, chemicals, extreme glare and
radiation. The Company offers a large number of task-specific non-prescription
safety eyewear products. The three basic categories of non-prescription eye and
face protection are non-prescription safety (or "plano") eyewear, goggles and
faceshields.
 
     - Plano (Non-prescription) Eyewear.  Plano eyewear accounts for the
       majority of the Company's sales in this category and includes a wide
       range of products from disposable visitor safety spectacles to several
       lines of fashionable, reusable safety eyewear available in different
       colors and with a variety of application -- specific lenses, frames and
       sideshields.
 
     - Goggles.  The Company manufactures and sells a broad line of goggles,
       which are typically preferred over plano eyewear in work environments
       where a higher degree of impact protection is required, where increased
       protection against dust, mist or chemical splash is needed and/or for use
       in welding
 
                                        2
<PAGE>   5
 
operations. To meet these requirements, the Company manufactures a variety of
vented and non-vented goggles with varying fields of view.
 
     - Faceshields.  Faceshields are designed to protect against heat, splash
       and flying particles and are often worn in conjunction with other
       protective equipment, such as plano eyewear and respirators.
 
     - Hard Hats.  The Company manufactures and sells a broad line of hard hats,
       including "bump" caps, full-brim hats and traditional hard hats,
       featuring four- or six-point suspension, ratchet adjustment, a wide
       selection of colors and custom imprinting.
 
FIRST AID KITS.  The acquisition of Eastern Safety Equipment Co., Inc.
("Eastern") on January 3, 1996 added first aid kits as a new product category
for the Company. First aid kits are either for general use or for industrial or
commercial uses.
 
RESPIRATORY PROTECTION.  Respiratory protection products are used to protect
against the harmful effects of atmospheric contamination and pollution caused by
dust, gases, fumes, sprays and other contaminants. The market for respiratory
protection products is segmented into two types: supplied air and air-purifying.
Supplied air respirators are further segmented into two types: self-contained
breathing apparatuses ("SCBA") and respirators supplied from a remote source of
air through a hose ("air line"). The Company competes in the air-purifying and
air line supplied segments of the respiratory protection market with a broad
line of disposable dust and mist masks, cartridge-equipped quarter-, half- and
full-face respirators, powered air-purifying respirators (whereby a battery
pumps air through cartridges), and "escape" respirators (a single-use respirator
for emergencies).
 
     SPECIALTY COMPOSITES
 
The Company's Specialty Composites operating unit manufactures a wide array of
impact-resistant, shock-absorbing and energy-absorbing materials for a variety
of noise, vibration and shock control applications using a wide range of
technologies, manufacturing processes and applications know-how. Specialty
Composites also produces the specially formulated foam used in the manufacture
of Safety Products' PVC ear plugs. The principal strengths of Specialty
Composites are its specialized polyurethane chemistry, its thin-sheet casting
capability, its composite technologies and its applications engineering. These
strengths allow the Company to manufacture in a single process, high value-added
materials and components with multiple chemistries and substrates using casting,
extrusion and molding processes.
 
Specialty Composites' products fall into three broad categories: barriers and
absorbers for noise control; damping and isolation products for vibration and
shock control; and energy control products for shock and comfort management. The
Company's products include: Isoloss LS polyurethane high density cellular foams,
which are manufactured by three production lines in a variety of thicknesses,
widths, colors and densities for mechanical vibration reduction, noise and shock
control and high resilience cushioning and sealing applications; the Confor
heavily damped viscoelastic foam for ergonomic cushioning applications; the
Tufcote polyurethane and PVC thin sheet foams for acoustical, absorption and
noise control applications; and the Isodamp PVC foams for mechanical vibration
reduction and noise and shock control.
 
Specialty Composite's products are sold into four market segments:
transportation; health-related; footwear; and other original equipment
manufacturers ("OEM") in industries such as electronics and communications.
 
TRANSPORTATION SEGMENT.  Specialty Composites' products are incorporated into
heavy trucks, automobiles, yachts, aircrafts, buses, leisure vehicles and
defense, farm and construction equipment in order to control noise, vibration
and shock. For example, the Company supplies durable acoustical foams and
barriers that control sound and help meet noise standards for Class VI-VII heavy
trucks. The Company also provides complete noise and vibration control packages
for high-end yachts in order to contain engine room noise and to soundproof
passenger quarters. Specialty Composites applications also exist with respect to
executive and commuter aircraft, where relatively thin, lightweight,
multi-function composites efficiently control sound and vibration.
 
                                        3
<PAGE>   6
 
HEALTH-RELATED SEGMENT.  Applications for the energy-absorbing characteristics
of Specialty Composites' products, particularly its line of temperature-reactive
foams, have been growing in the health-related segment. Such materials enhance
physical protection and improve comfort in many devices including leg braces,
orthotic devices, surgical pillows, wheelchair cushions, bicycle helmets,
keyboard wrist supports and occupational seating.
 
FOOTWEAR SEGMENT.  Specialty Composites supplies a durable and highly
shock-absorbent polyurethane foam, which is incorporated into insoles for
high-wear cushioning applications, such as athletic shoes, dress shoes, military
boots and work boots. Specialty Composites also offers an energy-absorbent
material to help protect against skeletal shock in military boots, work boots
and orthotic insoles.
 
OEM SEGMENT.  The Company produces an extensive assortment of polyurethane and
PVC die-cut and molded parts for vibration isolation and damping and for shock
protection and noise control in a wide range of other products, including
precision equipment and industrial machinery, computer disk drives, pagers,
industrial compressors and generator sets.
 
SALES AND MARKETING
 
The Company divides it sales force into two principal categories: Safety
Products and Specialty Composites.
 
SAFETY PRODUCTS OPERATING UNIT.  Within Safety Products, sales are divided into
eight channels: U.S. Industrial Distribution; U.S. Industrial Direct;
Consumer/Do-It-Yourself ("DIY"); Healthcare; Europe; Canada; Export; and
National Accounts. Each of these channels has its own sales force and its own
distinct sales strategies. In addition, through the acquisition of Peltor, the
Company has significantly expanded its sales coverage, including a dedicated
effort to serve the specialty communications ear muff market.
 
     - U.S. Industrial Distribution.  This is the largest sales channel for
       safety products and includes approximately 150 Dialog industrial
       distributors and approximately 120 industrial dealers. Participation in
       the Dialog program requires minimum purchase levels and support across
       the full product line, in return for rebates based on growth and volume
       and preferred treatment regarding shipping terms, new products, field
       sales support, and cooperative advertising. The Company also offers
       Dialog distributors financial incentives for establishing electronic
       order entry/invoicing with the Company, for developing a Company-specific
       training program for distributor sales personnel, for full-product line
       support and for engaging in annual business planning with the Company.
       The Company also has sales specialists calling directly on end users on
       behalf of its key Dialog distributors.
 
     - U.S. Industrial Direct.  Approximately 90% of the Company's safety
       prescription eyewear is sold directly to more than 40,000 industrial
       companies, including a majority of the industrial companies in the
       Fortune 500. The remainder of the Company's SRx products are sold through
       the industrial distribution channel. In most states, current laws require
       that prescription eyewear be dispensed to the user by a licensed optical
       professional, traditionally a local optician. As an alternative to this
       approach, in 1994 the Company introduced its Dispensing Manager program,
       whereby the Company employs its own licensed opticians to dispense
       prescription safety eyewear.
 
     - Consumer/DIY.  The Company is the leading supplier of safety products to
       the consumer/DIY market and is the primary supplier to such leading
       retailers as ACE, Home Depot, Lowe's, Sears, TrueValue and Servi-Star.
       The Company offers both its AOSafety brand of industrial grade products
       in consumer packaging and its Eastern brand of consumer grade product in
       consumer packaging.
 
     - Healthcare.  The Company maintains its own national sales manager and has
       an exclusive arrangement with an independent representative group to
       pursue the growing use of PPE in the healthcare sector and has 
       developed a specialized line of healthcare products with the goal of 
       building a national distribution network. Use of the Company's products
       can assist in compliance by healthcare professionals with recently 
       introduced OSHA regulations designed to reduce the risk of diseases 
       associated with blood-borne pathogens and dealing with splash control.
 
                                        4
<PAGE>   7
 
     - Europe.  The Company has a significant presence in Europe with sales
       offices in the U.K., Sweden, Germany, France, Denmark, Italy and Spain.
       Since the acquisition of Peltor, the Company has begun the process of
       consolidating its sales offices across Europe. While the Company's
       historical strength in this market has been in hearing protection devices
       sold through industrial distributors, the Company has recently been
       successful in pursuing sales of safety eyewear and has dedicated a
       full-time eyewear product sales manager to lead and train the existing
       sales organization.
 
     - Canada.  In Canada, the Company has a strong position in both stock
       safety products and prescription safety eyewear. Just as in the United
       States, prescription safety eyewear is sold primarily on a direct basis
       to industrial firms, while stock safety products are sold through
       distributors.
 
     - Export.  The Company exports its products around the world, and this
       channel is managed through sales representatives located in Singapore
       (covering Southeast Asia), Miami (covering Latin America), and Sydney
       (covering Australia and New Zealand).
 
     - National Accounts.  The Company has two dedicated national accounts sales
       managers calling on the U.S. Government and major PPE users such as Ford
       Motor Company and General Motors.
 
SPECIALTY COMPOSITES OPERATING UNIT.  The Company relies upon independent
manufacturer representatives and the Company's factory sales representatives to
identify OEM applications for Specialty Composites' products and technologies.
Once such applications have been identified, the Company's sales and technical
staff work closely with OEMs to provide the customer with a low-cost, integrated
solution for its noise, vibration, shock, cushioning and/or comfort management
problems.
 
RESEARCH AND DEVELOPMENT
 
SAFETY PRODUCTS OPERATING UNIT.  The Company believes that its research and
development facilities, personnel and programs are among the best in the PPE
industry. Since its inception in 1972, the Company's ultimate predecessor, the
former E-A-R (Energy Absorbing Resins) Division of Cabot Corporation ("Cabot"),
has been a leader in the development of technology for understanding and
measuring noise and hearing loss and in developing products to protect against
such loss. In order to test the efficacy of its hearing protection products, the
Company owns and operates the only privately-owned National Voluntary Laboratory
Accreditation Program ("NVLAP") laboratory in the United States accredited for
testing the efficacy of hearing protection products. The Company also operates
sound chambers and testing facilities which measure the performance of its
materials and designs. Similarly, the Company believes that it has been a
pioneer and leader in the development and testing of safety eyewear and
maintains extensive facilities for the design and testing of safety eyewear. The
research and development personnel of the Company include recognized experts in
the safety products industry.
 
SPECIALTY COMPOSITES OPERATING UNIT.  The research and development efforts of
Specialty Composites focus on developing proprietary materials and enhancing
existing products in order to meet customer needs identified by the Company's
sales and technical staff. Products such as the Isoloss LS polyurethane high
density cellular foams and the Confor heavily damped viscoelastic foam are being
introduced in a growing number of applications across all markets served by
Specialty Composites.
 
The Company does not engage in any customer-sponsored research and development
projects.
 
RAW MATERIALS AND SUPPLIERS
 
The Company consumes a wide variety of raw materials, supplies and components,
including, among others, paper products, chemicals, eyewear frames and optical
lenses. The paper products category includes corrugated paper, folding cartons
and packaging materials. The chemicals category includes plastic resins such as
polycarbonate and propionate, as well as polyols, plasticizers, substrates,
isocyanates and adhesives. The eyewear frames category includes frames for SRx
products.
 
The Company has a diversified base of raw material suppliers. The Company does,
however, use single sources for the supply of several raw materials, including
General Electric Plastics, a division of General
 
                                        5
<PAGE>   8
 
Electric Company, for polycarbonate resin, the primary raw material used in the
production of the Company's non-prescription optical lenses. The Company has not
experienced any significant delays or shortages in obtaining raw materials in
recent years and believes that alternative supplies of raw materials can be
located on commercially reasonable terms.
 
The Company outsources the production of less than 10% of its products to
various manufacturers. Competition among these manufacturers is strong, and,
although a change in manufacturers often results in a period of adjustment
concerning product quality and distribution, the Company, in the past, has
changed manufacturers with respect to certain of its outsourced products.
 
MANUFACTURING AND DISTRIBUTION OPERATIONS
 
The Company maintains a high degree of vertical integration, allowing it to
manufacture over 90% of the products that it sells. The Company's strengths
include the manufacture of foams (casting, molding and fabricating) for
Specialty Composites products (including the foam used in the manufacture of PVC
ear plugs); high speed assembly and packaging of ear plugs; plastic injection
molding, coating and assembly of non-prescription eyewear; and assembly,
grinding, polishing and coating of prescription eyewear. Consistent across all
of the Company's manufacturing operations is an emphasis on producing high
quality products. Currently, eight of the Company's manufacturing facilities
have been awarded ISO 9002 or ISO 9001 certification, indicating that the
Company has achieved and sustained a high degree of quality and consistency with
respect to its products. The Company believes that ISO certification is an
increasingly important selling feature both domestically and internationally,
and certain customers require ISO certification from all their vendors.
 
The Company's products are generally shipped within several days from the
receipt of a purchase order. As a result, backlog is not material to the
Company's business.
 
SAFETY PRODUCTS OPERATING UNIT.  The Company's Indianapolis, Indiana plant is
the largest ear plug manufacturing facility in the world. It fabricates, molds
and packages hundreds of millions of pairs of ear plugs annually, utilizing
automated, high speed assembly and packaging equipment. Because the economies of
scale present in this operation are unique in the hearing protection products
industry, management believes that they offer the Company a competitive
advantage of lower costs within the production process. The plant's high-speed
robotic fabrication, assembly and packaging of ear plugs facilitate cost-saving,
high-volume production and improve cycle time and inventory management. Other
safety products are manufactured at the Southbridge, Massachusetts facility,
where the Company invested over $2 million in industrial robotics and cellular
manufacturing to produce plano eyewear products previously outsourced from
southeast Asia. As a result, the Company is now able to advertise these products
as "Made in the USA."
 
The Company fills virtually all of its domestic and certain of its international
orders, other than SRx, through its state-of-the-art distribution center located
in Indianapolis, Indiana which has efficient bar-coding and scanning
capabilities to assure rapid turn-around time and service levels for customer
orders.
 
Over the past three years the Company completed a major program to consolidate
and retool its SRx laboratory operations. The SRx production operations of six
different manufacturing facilities were consolidated into two U.S. facilities
that possess new lens surfacing, edging and grinding machinery capable of
handling glass, plastic and polycarbonate lenses. These two facilities currently
manufacture and distribute over 500,000 pairs of safety prescription glasses
annually.
 
The Company's principal international manufacturing operations are located in
Poynton, England; Mississauga, Ontario; Varnamo, Sweden; and Montreal, Quebec.
The Poynton facility serves customers in Western Europe, producing and packaging
ear plugs and other hearing and eyewear products. In addition, Poynton has an
SRx laboratory that primarily serves the U.K. market. The Mississauga plant
fabricates prescription eyewear and, together with a small prescription eyewear
laboratory in Montreal, produces SRx products for the Canadian market. The
Varnamo, Sweden plant is the principal Peltor manufacturing location; finished
goods and components are shipped to customers and other Peltor subsidiaries from
this location.

SPECIALTY COMPOSITES OPERATING UNIT.  Specialty Composites' products are
manufactured in Indianapolis, Indiana and Newark, Delaware. The Indianapolis
plant, which supplies specially formulated foam for the Company's PVC ear plugs,
manufactures and fabricates sheet and roll PVC and polyurethane materials and
molds polyurethane foams and solids. This facility also houses applications
engineering, research and development, quality assurance and customer service
support. The Newark, Delaware facility manufacturers polyurethane foams and
films and houses the Company's new proprietary, thinsheet foam casting line,
which will permit the casting of both sheet and composite materials, including
facings and substrates, in a single pass through the line. The new casting line,
which is estimated to cost approximately $5.0 million, is fully operational, but
is not yet in full production mode.
 
COMPETITION
 
The PPE market is fragmented and highly competitive. The Company estimates that
there are 500 manufacturers of PPE (other than safety clothing, gloves and
shoes) in the United States, Europe and Southeast Asia. Participants in the
industry range in size from small, independent, single-product companies with
annual sales of less than $15 million, to a small number of multinational
corporations with annual sales in excess of $100 million. The Company believes
that participants in the PPE market compete primarily on the basis of product
characteristics (such as design, style and functional performance), product
quality, service and brand name recognition and, to a lesser extent, price. From
a positive competitive standpoint, the Company believes it is well situated,
primarily because of its large size and its broad product offerings, to compete
in a fragmented industry. The Company enjoys certain economies of scale which
are not available to smaller competitors. Many of the Company's customers,
particularly in the growing consumer/DIY channel, prefer the type of "one stop
shopping" that the Company can provide. The Company's advanced distribution
center further facilitates timely and accurate deliveries.
 
The specialty composites industry is highly competitive, and participants
compete on the basis of being able to provide cost-effective solutions to the
noise, shock and vibration problems of OEMs.
 
EMPLOYEES
 
As of September 30, 1996, the Company had 1,875 employees, of whom 1,172 were
primarily engaged in manufacturing, 490 in sales, marketing and distribution, 64
in research and development and 149 in general and administrative. The Company
believes its employee relations are good. The Company has one facility that
employs union members. This facility, located in Plymouth, Indiana, employs 63
members of the International Union of Electronic, Electrical, Salaried, Maritime
and Furniture Workers (out of a total of 101 employees), and the Company's
relations with these union members are fully satisfactory. The union contract
expires on June 30, 1998.
 
PATENTS AND TRADEMARKS
 
The Company owns and has obtained licenses to various domestic and foreign
patents, patent applications and trademarks related to its products, processes
and business. The Company values particularly highly its trademark for the color
yellow for ear plugs in the United States and Canada and places significant
value on its overall patent portfolio. However, no single patent or patent
application is material to the Company. The Company's patents expire at various
times over the next 17 to 20 years.
 
GOVERNMENT REGULATION
 
As a manufacturer of safety products, the Company is subject to regulation by
numerous governmental bodies. Principal among the federal regulatory agencies in
the United States are: the Occupational Safety and Health Administration
("OSHA"), which regulates the usage of all PPE, with the exception of
respirators; the Environmental Protection Agency ("EPA"), which regulates
hearing protection devices; the Mine Safety and Health Administration ("MSHA")
and the national Institute of Occupational Safety and Health ("NIOSH"), both of
which certify respirators; and the Food and Drug Administration ("FDA"), which
regulates eye, face and respiratory protection products for the healthcare
industry. These agencies generally
 
                                        7
<PAGE>   10
 
mandate that the Company's products meet standards established by private
groups, such as American National Standards Institute ("ANSI"). The Company's
products are also subject to foreign laws and regulations. In particular, they
must comply with the Canadian Standards Association, European Committee for
Normalization and Standards Australia. The Company believes it is in compliance
in all material respects with the regulations and standards of these
governmental bodies, and any failures to comply with such regulations and
standards in the past have not had a material adverse effect on its business.
 
ENVIRONMENTAL MATTERS
 
The Company is subject to various evolving federal, state and local
environmental laws and regulations governing, among other things, emissions to
air, discharge to waters and the generation, handling, storage, transportation,
treatment and disposal of hazardous substances and wastes. The Company believes
that it is in substantial compliance with all such laws and regulations.
 
ITEM 2.  PROPERTIES
 
The Company owns and/or leases facilities in the United States, Canada, Europe,

and (iv) the Safety Products manufacturing facility in Ettlingen, Germany. The
Company believes that it will be able to renew each of its leases upon their
respective expiration dates on commercially reasonable terms. In addition, the
Company believes that it would be able to lease suitable additional or
replacement space on commercially reasonable terms.
 
ITEM 3.  LEGAL PROCEEDINGS
 
Various lawsuits and claims arise against the Company in the ordinary course of
its business. Most of these lawsuits and claims relate to the Company's safety
eyewear and respiratory product lines and primarily involve accidents and/or
exposures occurring after the Company's predecessor acquired the AOSafety
Division from American Optical Corporation in April 1990. The Company is
contingently liable with respect to numerous lawsuits involving respirators
manufactured by American Optical Corporation prior to the acquisition of the
AOSafety Division in April 1990. These lawsuits typically involve plaintiffs
alleging that they suffer from asbestosis or silicosis, and that such condition
results in part from respirators which were negligently designed or
manufactured. The defendants in these lawsuits are often numerous, and include,
in addition to respirator manufacturers, employers of the plaintiffs and
manufacturers of sand (used in sand blasting) and asbestos. Responsibility for
legal costs, as well as for settlements and judgments, is shared contractually
by the Company, American Optical Corporation and a prior owner of American
Optical Corporation. The Company and Cabot have entered into an arrangement
relating to certain respirator claims asserted after July 11, 1995 (the date of
the Company's formation) whereby, so long as the Company pays to Cabot an annual
fee of $400,000, which the Company has elected to pay, Cabot will retain
responsibility and liability for, and indemnify the Company against, certain
legal claims alleged to arise out of the use of respirators manufactured prior
to July 1995. The Company has the right to discontinue the payment of such
annual fee at any time, in which case the Company will assume responsibility for
and indemnify Cabot with respect to such claims.
 
In 1995 the Company became aware that its French subsidiary had for a period of
at least one year been delinquent in the remittance of value added tax payments
to the French government. The Company believes that any required tax payments
and attendant penalties will not have a material adverse effect on the Company's
financial condition or results of operations. The Company is indemnified by
Cabot in respect of any such payments and penalties.
 
The Company recently received a complaint from Gargoyles, Inc. alleging that one
of the Company's recently introduced plano eyewear products (Fectoids) infringes
a patented lens shape utilized in the plaintiff's sun and sporting glasses. The
Company is defending this allegation vigorously.

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
 
All of the common stock, par value $0.01 per share, of Aearo ("Aearo Common
Stock") is held, collectively, by Vestar Equity Partners, L.P. (together with
certain related persons, "Vestar"), Cabot Corporation ("Cabot") and management.
In July 1995, Vestar, Cabot and management effected through the Company the
acquisition of substantially all of the assets and certain liabilities of Cabot
CSC Corporation ("Old Cabot Safety Corporation"), a wholly-owned subsidiary of
Cabot, and certain of its affiliates (the "Formation Acquisition") for $206.1
million. To finance the Formation Acquisition, the Company incurred $47.5
million of senior secured debt ("Senior Bank Facilities") sold $100 million of
12 1/2% senior subordinated notes due 2005 (the "Subordinated Notes"), issued to
Vestar and Cabot an aggregate of $45 million of 12 1/2% redeemable preferred
stock (the "Aearo Preferred Stock"), and issued to Vestar, Cabot and certain
members of management and key employees of the Company (collectively the
"Management Investors") an aggregate of 100,000 shares of Aearo Common Stock.
See Item 12, "Security Ownership of Certain Beneficial Owners and Management."
All of the common stock of the Subsidiary is owned by Aearo, and thus no trading
market exists for such stock. Accordingly, no trading market exists for any
capital stock of the Company.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
The following discussion should be read in conjunction with "Selected Financial
Data," and the financial statements of the Company, including notes thereto,
appearing elsewhere in this Report. This Report contains forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. The Company's actual results
could differ materially from those set forth in such forward-looking statements.
The factors that might cause such a difference include, among others, the
following: risks associated with indebtedness; risks related to acquisitions;
risks associated with the conversion to a new management information system;
high level of competition in the Company's markets; importance and costs of
product innovation; risks associated with international operations; product
liability exposure; unpredictability of patent protection and other intellectual
property issues; dependence on key personnel; the risk of adverse effect of
economic and regulatory conditions on sales; and risks associated with
environmental matters.
 
GENERAL
 
Prior to the Formation Acquisition in July 1995, Old Cabot Safety Corporation
was a wholly-owned subsidiary of Cabot. In 1990, Cabot combined into Old Cabot
Safety Corporation the operations of its E-A-R Division with the operations of
the AOSafety Division, which Cabot acquired from American Optical Corporation at
such time. The combined financial statements of the Company include the results
of Old Cabot Safety Corporation and certain of its affiliates whose operations
are partially or exclusively related to the business of the Company.
 
The Company's current senior management team was installed in mid-1994 to
address operational issues that had adversely affected the Company's sales and
profitability. Management focused on four primary areas: (i) strengthening
relationships with distributors and product end-users, (ii) increasing the
Company's participation in projected high-growth markets, such as the
consumer/DIY and catalog supply markets and the emerging international markets
of Latin America and the Pacific Rim, (iii) expanding product innovation and
development efforts and (iv) pursuing acquisitions. Management believes that the
Company's performance in fiscal 1996 reflects the benefits of these initiatives,
as well as the associated increased investment in sales and marketing and
information systems.
 
The operational issues addressed by management after 1994 included a decline in
profitability in fiscal 1993 and the early part of fiscal 1994 following the
combination of the E-A-R Division and the AOSafety Division. While the
combination resulted in a larger company with broader product offerings, giving
E-A-R distributors access to AOSafety products and vice versa, it resulted in
some long-standing relationships among the Company, distributors and end-users
being undermined. In addition, as part of the combination the Company reduced
its sales force while expanding the product line, which resulted in decreased
distribution focus and support of the Company's products by distributors. During
the late 1980s the Company had also suffered from a prolonged lack of investment
in product innovation and development. Because end-users are relatively slow to
switch products or brands, the combined effect of the deteriorating distributor
relations and the lack of new products did not adversely affect financial
results in fiscal 1991 and 1992. However, the combined effect of such problems,
coinciding with the introduction of new products by competitors, began to result
in some loss of market share in fiscal 1992. In an effort to retain market
share, the Company began to offer price promotions and reduced the prices of
several products. While this aided financial performance in fiscal 1992, it
largely did so at the expense of fiscal 1993 results by pulling business
forward. The reduction in pricing, however, did not stem the market share
erosion, as many end-users are more interested in product performance and
increased safety compliance than they are in discounted prices. Operating profit
in fiscal 1993 and the first half of fiscal 1994 was also negatively affected by
the costs of consolidating the prescription eyewear manufacturing facilities
from six locations to two and consolidating the Company's other manufacturing
facilities at its Southbridge, Massachusetts location.

(1) Excludes $3.6 million charged to cost of sales as a result of purchase price
    allocated to acquired inventory. This amount was recorded in cost of sales
    as the acquired inventory was sold during the period ended September 30,
    1995.
 
(2) Excludes $1.1 million charged to selling and administrative expense for the
    termination of the Old Cabot Safety Corporation stock option plan and $0.8
    million charged to selling and administrative expense attributable to
    penalties incurred by the Company's French subsidiary. See "Business--Legal
    Proceedings."
 
(3) Excludes $1.0 million charged to cost of sales as a result of purchase price
    allocated to inventory acquired in the Peltor acquisition. This amount was
    recorded in cost of sales as the acquired inventory was sold during the year
    ended September 30, 1996.
 
(4) Excludes $0.8 million charged to selling and administrative expense for
    costs related to the abandoned effort at an initial public offering.
</TABLE>
 
The Company's business is slightly seasonal. Traditionally, net sales during the
first fiscal quarter (October 1 -- December 31) are slightly lower than the
other quarters. This is generally attributable to stock reductions by
distributors and plant shutdowns by end-users towards the end of each calendar
year.
 
OVERVIEW
 
The combined financial statements of the Company for the periods prior to July
12, 1995 have been prepared on the historical cost basis. The consolidated
balance sheets of the Company at September 30, 1995 and 1996 reflect allocation
of the purchase price to the assets acquired and thus are not comparable with
the historical balance sheets presented for prior periods. Operating results
subsequent to the Formation Acquisition are comparable to prior periods, with
the exception of cost of sales (due to the $3.6 million and $1.0 million charges
in the period and year ended September 30, 1995 and 1996, respectively, related
to the allocations of purchase price to inventory), depreciation expense,
amortization of intangible assets and interest expense.
 
FISCAL 1996 COMPARED TO FISCAL 1995
 
NET SALES.  Net Sales in the year ended September 30, 1996 increased 20.2% to
$243.5 million from $202.6 million in the year ended September 30, 1995. The
increase in net sales was due to the acquisition of Peltor and Eastern as well
as internal growth at Safety Products and Specialty Composites. Safety Products
net sales increased 20.9% from $169.7 million to $205.2 million. Of this $35.5
million increase, $12.8 million resulted from owning Peltor for four months,
$10.9 million resulted from owning Eastern for nine months, and $11.8 million
was from internal growth. There was growth in revenue of hearing products due to
better realized
 
                                       13
<PAGE>   16
 
prices and new products, in eye and face products due to increased volumes and
new products, and in prescription safety eyewear as a result of higher volume
from new accounts. Growth in the fourth quarter was hampered by the conversion
to a new computer system. The conversion effort resulted in inaccurate
production planning, back orders and missed shipments, particularly in eye and
face products manufactured at the Company's Southbridge, Massachusetts facility.
Specialty Composites net sales increased 16.3% from $32.9 million to $38.3
million. This increase was due to a $2.3 million contract in December of 1995 to
supply materials for the Sea Wolf submarine and growth in sales to the
transportation markets.
 
GROSS PROFIT.  Gross Profit in the year ended September 30, 1996 increased 28.4%
to $109.9 million from $85.6 million in the year ended September 30, 1995. Gross
profit, adjusted for the impact of inventory purchase accounting adjustment
charges of $3.6 million and $1.0 million in fiscal 1995 and 1996, respectively,
increased 24.3% to $110.9 million from $89.2 million. The increase was a result
of the acquisitions, improved pricing and margins, and internal sales growth. On
an adjusted basis, gross profit as a percentage of sales in the year ended
September 30, 1996 would have been 45.6% as compared to 44.0% in the year ended
September 30, 1995. The percentage increase was due to the combined effect of
the Peltor acquisition, as the Peltor product line has higher gross margins, and
improved margins in the base business which more than offset the effect of the
Eastern product line, which has lower gross margins.
 
SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses in the
year ended September 30, 1996 increased 22.1% to $73.6 million from $60.3
million in the year ended September 30, 1995. In the year ended September 30,
1996, the Company incurred $0.8 million of costs associated with the abandoned
efforts at an initial public offering (IPO). Excluding these costs, as well as
$1.1 million in costs in fiscal 1995 related to the termination of the Old Cabot
Safety Corporation stock option plan and a $0.8 million charge relating to a
provision for penalties by the Company's French subsidiary, selling and
administrative expenses would have increased 24.7% to $72.8 million from an
adjusted $58.4 million in fiscal 1995. Such expenses as a percentage of net
sales would have been 29.9% as compared to 28.8% in fiscal 1995. The increase in
expenses is partially attributable to higher selling expenses from the Company's
expanded sales programs, higher distribution and administrative expenses during
the fourth quarter as a result of partial shipments and back orders and the
direct costs incurred in absorbing the conversion to a new computer system.
 
RESEARCH AND TECHNICAL EXPENSES.  Research and technical expenses in the year
ended September 30, 1996 increased 15.1% to $3.3 million from $2.8 million in
the year ended September 30, 1995. The increase was the result of the
acquisition of Peltor as well as increased expenses for product development.
 
OPERATING INCOME.  Primarily as a result of the factors discussed above,
operating income in the year ended September 30, 1996 increased 55.6% to $27.2
million from $17.5 million in the year ended September 30, 1995. Excluding the
inventory charges related to purchase accounting as well as the costs of the
abandoned IPO effort in 1996 and the costs of the Old Cabot Safety Corporation
stock option plan and charges related to the French subsidiary, operating income
would have been $29.0 million in the year ended September 30, 1996 and 23.0
million in the year ended September 30, 1995 representing an increase of 26.2%.
 
INTEREST EXPENSE, NET.  Net interest expense is not comparable with prior
periods as a result of the financing related to the Formation Acquisition and
the Peltor acquisition. Interest expense in the year ended September 30, 1996
was $20.7 million.
 
PROVISION FOR INCOME TAXES.  The provision for income taxes in the year ended
September 30, 1996 was $4.3 million or 66.2% of income before provision for
income taxes. Such rate was higher than the Company's normalized rate of 40% as
the interest expense on the borrowings for the Peltor acquisition could not be
used to offset income taxes in Sweden until after September 30, 1996.
 
NET INCOME.  The increase in interest expense and the higher tax provision
resulted in a 48.1% decrease in net income to $2.2 million from $4.2 million.
 
FISCAL 1995 COMPARED TO FISCAL 1994
 
NET SALES.  Net sales in the year ended September 30, 1995 increased 13.6% to
$202.6 million from $178.3 million in the year ended September 30, 1994. The
increase in net sales was due to increased sales by both
 
                                       14
<PAGE>   17
 
Safety Products and Specialty Composites. Safety Products' net sales in the year
ended September 30, 1995 increased 13.4% to $169.7 million from $149.7 million
in the year ended September 30, 1994. This increase was primarily a result of
(i) increased volume in its eye and face segment due to strong demand for the
Company's Nassau Plus eyewear which was introduced in May 1994, (ii) increased
volume in the hearing segment largely due to increased European sales as a
result of improving economies and the announced Common European (CE) market
standards and (iii) increased sales of prescription safety eyewear due to an
increase in realized prices from the sale of premium frames and lenses partially
due to the recently initiated Dispensing Manager program, pursuant to which the
Company employs (rather than independently contracting for) eyecare
professionals. Management believes the enhanced sales and marketing efforts
which commenced in the second half of fiscal 1994 contributed to these
increases, which were achieved despite the loss of the Company's only
significant private label personal protection customer in March 1994. Specialty
Composites net sales in the year ended September 30, 1995 increased 15.3% to
$32.9 million from $28.6 million in the year ended September 30, 1994. This
increase was primarily the result of increased demand for the Company's products
by transportation and precision equipment manufacturers.
 
GROSS PROFIT.  Excluding the $3.6 million negative effect of purchase
accounting, gross profit in the year ended September 30, 1995 increased 13.3% to
$89.2 million from $78.8 million in the year ended September 30, 1994. The
increase in cost of sales related to the Formation Acquisition was due to a $3.6
million charge related to allocation of purchase price to finished goods
inventory. This amount was recorded in cost of sales as the acquired inventory
was sold during the period ended September 30, 1995. The increase in gross
profit was primarily the result of increased volumes of both Safety Products and
Specialty Composites sales. Gross profit as a percentage of net sales in the
year ended September 30, 1995 was 44.0% as compared to 44.2% in the year ended
September 30, 1994. Such percentage was essentially flat because increased
margins at Safety Products were partially offset by higher proportionate sales
growth at Specialty Composites, which has lower gross profit margins than Safety
Products, as well as the loss of the margin contribution from the private label
personal protection customer mentioned above.
 
SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses in the
year ended September 30, 1995 increased 16.7% to $60.3 million from $51.7
million in the year ended September 30, 1994. This increase was primarily the
result of an approximately 10.0% increase in the Company's sales force, as well
as increased distribution costs resulting from greater shipments and the costs
of occupying a new U.S. distribution center and higher administrative costs
resulting from the Formation Acquisition. In addition, the Company incurred a
$1.1 million charge related to the termination of the Old Cabot Safety
Corporation stock option plan, as well as a $0.8 million charge relating to a
provision for tax penalties by the Company's French subsidiary (see
"Business -- Legal Proceedings"). Excluding these charges, selling and
administrative expenses as a percentage of net sales in the year ended September
30, 1995 would have declined to 28.8% as compared to 29.0% in the year ended
September 30, 1994. This was primarily the result of the increase in net sales
from the Company's enhanced sales and marketing efforts which commenced in
fiscal 1994. These efforts include the Sales Specialist program which targets
end-users of the Company's products, as well as the Dispensing Manager program,
which provides improved service and fulfillment to the Company's prescription
eyewear customers.
 
RESEARCH AND TECHNICAL SERVICES EXPENSES.  Research and technical services
expenses in the year ended September 30, 1995 increased 3.3% to $2.8 million
from $2.7 million in the year ended September 30, 1994. This increase was
primarily the result of increased respiratory product development efforts, as
well as increased training development work with end-users, including the
reinstatement of hearing clinics.
 
OPERATING INCOME.  Primarily as a result of the factors discussed above,
operating income in the year ended September 30, 1995 decreased 7.2% to $17.5
million from $18.8 million in the year ended September 30, 1994. Excluding a
$1.1 million payment related to the termination of the Old Cabot Safety
Corporation stock option plan and a $0.8 million charge relating to a provision
for tax penalties by the Company's French subsidiary (see "Business -- Legal
Proceedings") and a $3.6 million charge related to the allocation of purchase
price to inventory, operating income would have been $23.0 million, a 22.2%
increase.
 
                                       15
<PAGE>   18
 
INTEREST EXPENSE, NET.  Interest expense, net, is not comparable with prior
periods as a result of the financing related to the Formation Acquisition.
Interest expense for the Company after the Formation Acquisition was $4.1
million, reflecting the increased levels of debt.
 
NET INCOME.  Primarily as a result of the factors discussed above, net income in
the year ended September 30, 1995 decreased 47.5% to $4.2 million from $8.0
million in the year ended September 30, 1994. Excluding a $1.1 million payment
related to the termination of the Old Cabot Safety Corporation stock option plan
and a $0.8 million charge relating to a provision for tax penalties by the
Company's French subsidiary (see "Business -- Legal Proceedings") and a $3.6
million charge related to the allocation of purchase price to inventory, net
income would have been $7.8 million, a 2.2% decrease.
 
FISCAL 1994 COMPARED TO FISCAL 1993
 
NET SALES.  Net sales in fiscal 1994 increased 5.1% to $178.3 million from
$169.6 million in fiscal 1993. The increase in net sales was due to increased
sales by both Safety Products and Specialty Composites. Safety Products' net
sales in fiscal 1994 increased 4.0% to $149.7 million from $143.9 million in
fiscal 1993. This increase was primarily the result of increased volume in the
eye and face segment due to strong demand for the Company's Nassau Plus eyewear
following its introduction in May of 1994. This increase was partially offset by
the loss of the Company's only significant private label customer in the
Company's hearing segment in March 1994. Specialty Composites net sales in
fiscal 1994 increased 11.3% to $28.6 million from $25.7 million in fiscal 1993.
This increase was primarily the result of increased demand from transportation
manufacturers and was partially offset by a decline in demand from a
defense-related manufacturer.
 
GROSS PROFIT.  Gross profit in fiscal 1994 increased 8.0% to $78.8 million from
$73.0 million in fiscal 1993. This increase was primarily the result of
increased gross profit contribution in Safety Products' eye and face segment as
a result of new products and higher sales volumes. Gross profit as a percentage
of net sales in fiscal 1994 increased to 44.2% from 43.0% in fiscal 1993. This
increase was primarily the result of the higher margins in the prescription
eyewear segment in the second half of the fiscal year as a result of the
benefits of the consolidation of the Company's prescription eyewear
manufacturing facilities, which was completed in the first quarter of fiscal
1994 and resulted in additional costs of sales of approximately $1.5 million in
fiscal 1994. The percentage increase was achieved despite the lost margin
contribution from the private label customer mentioned previously.
 
SELLING AND ADMINISTRATIVE EXPENSES.  Selling and administrative expenses in
fiscal 1994 increased 13.9% to $51.7 million from $45.3 million in fiscal 1993.
This increase was primarily the result of (i) increased expenses associated with
increased volumes, (ii) new sales and marketing initiatives including the Sales
Specialist and Dispensing Manager programs and (iii) severance and relocation
costs related to several changes in senior management positions of the Company.
Selling and administrative expenses as a percentage of net sales in fiscal 1994
increased to 29.0% from 26.7% in fiscal 1993. This increase was primarily the
result of the increased expenses in connection with new sales and marketing
initiatives described above which did not lead to increased sales until the
latter part of fiscal 1995 and the six months ended March 31, 1996.
 
RESEARCH AND TECHNICAL SERVICES EXPENSES.  Research and technical services
expenses in fiscal 1994 increased 20.0% to $2.7 million from $2.3 million in
fiscal 1993. This increase was primarily the result of increased product
development and end-user technical services and training programs.
 
OPERATING INCOME.  Primarily as a result of the factors discussed above,
operating income in fiscal 1994 decreased 3.9% to $18.8 million from $19.6
million in fiscal 1993.
 
INTEREST EXPENSE, NET.  Interest expense, net, in fiscal 1994 increased 22.0% to
$5.8 million from $4.8 million in fiscal 1993. This increase was primarily the
result of higher borrowings to finance the payment of a $25.0 million dividend
to Cabot in December 1993.
 
NET INCOME.  Primarily as a result of the factors discussed above, net income in
fiscal 1994 decreased 15.2% to $8.0 million from $9.4 million in fiscal 1993.
Net income in fiscal 1993 reflects a $0.3 million addition due to a cumulative
effect of accounting changes.

EFFECTS OF CHANGES IN EXCHANGE RATES
 
In general, the Company's results of operations are affected by changes in
exchange rates. Subject to market conditions, the Company prices its products in
Europe and in Canada in local currency. While many of the Company's selling and
distribution costs are also denominated in these currencies, a large portion of
the product costs are U.S. dollar denominated. As a result, a decline in the
value of the U.S. dollar relative to these other currencies can have a favorable
effect on the profitability of the Company and an increase in the value of the
U.S. dollar relative to these other currencies can have a negative effect on the
profitability of the Company. During fiscal 1993 and fiscal 1994 the U.S. dollar
increased in value relative to most of the European currencies, as well as the
Canadian dollar. The Company estimates that this had the effect of decreasing
operating profit by $1.9 million in fiscal 1993 and $0.5 million in fiscal 1994.
In the year ended September 30, 1995, the U.S. dollar decreased in value
relative to most of the European currencies, but increased in value relative to
the Canadian dollar. The Company estimated that these changes had the effect of
increasing operating profit by $0.9 million in the year ended September 30,
1995. In the year ended September 30, 1996, the average U.S. dollar exchange
rate appreciated versus major European currencies and depreciated versus the
Canadian dollar when compared to fiscal year 1995. The Company estimates that
the net impact of these fluctuations to operating profit is a reduction of
approximately $0.2 million. As a result of the acquisition of Peltor, the
Company's future results of operations will be affected by changes in exchange
rates relative to the Swedish Krona. A decline in the value of the Krona
relative to other currencies could have a positive effect on the Company's
results of operations, and an increase in the value of the Krona relative to
other currencies could have a negative effect on the Company's result of
operations.
 
EFFECTS OF INFLATION
 
In recent years, inflation has been modest and has not had a material impact
upon the results of the Company's operations.
 
LIQUIDITY AND CAPITAL RESOURCES
 
The Company's sources of funds have consisted primarily of operating cash flow
and debt financing. The Company's uses of those funds consist principally of
debt service, capital expenditures and acquisitions.
 
The required amortization payments under the Company's Senior Bank Facilities
are $8.8 million in fiscal 1997, $11.1 million in fiscal 1998, $13.8 million in
fiscal 1999, $16.4 million in fiscal 2000, $21.3 million in fiscal 2001, $34.3
million in fiscal 2002 and $35.3 million in fiscal 2003. Other than upon a
change of control or as a result of certain asset sales, or in the event that
certain excess funds exist at the end of a fiscal year, the Company will not be
required to make any principal payments in respect of the Subordinated Notes
until maturity. The Company will also be required to make interest payments with
respect to both the Senior Bank Facilities and the Subordinated Notes.
 
The Company typically makes capital expenditures related primarily to the
maintenance and improvement of manufacturing facilities. The Company spent $9.3
million for capital expenditures for the year ended September 30, 1996 as
compared to $13.2 million for the year ended September 30, 1995. Included in the
capital expenditures over the past two years was an aggregate of $5.0 million
for a casting line at the Newark, Delaware facility and $7.0 million for a
worldwide management information system. The Company's capital spending is of a
relatively short duration, with the complete commitment process involving less
than one year. In fiscal 1992, 1993 and 1994 capital expenditures were $5.1
million, $9.0 million and $4.5 million respectively.
 
The Company's principal source of cash to fund these capital requirements is net
cash provided by operating activities. The Company's net cash provided by
operating activities for the year ended September 30, 1996 totaled $4.5 million
as compared to $24.9 million for the year ended September 30, 1995. The decrease
was due to an increase in receivables of $4.4 million and an increase in
inventories of $3.7 million. These increases were partially due to the Company's
conversion to a new computer system which resulted in higher receivables due to
a high level of shipments during the latter part of September as well as billing
discrepancies and higher inventories due to difficulties in production planning.
Accounts payable and accruals
 
                                       17
<PAGE>   20
 
decreased $3 million partially due to payments of accrued fees and expenses from
the Formation Acquisition during fiscal 1996 and partially due to payment for
capital expenditures incurred during fiscal 1995. In fiscal 1992, 1993 and 1994,
the Company's net cash provided by operating activities totaled $22.6 million,
$25.8 million, and $17.9 million. The decrease in net cash provided by operating
activities in fiscal 1994 was primarily caused by a $4.1 million increase in
non-cash working capital in fiscal 1994 as compared to a $1.6 million decrease
in non-cash working capital in fiscal 1993.
 
Net cash used by investing activities was $96.4 million for the year ended
September 30, 1996 as compared to $16.2 million (excluding the Formation
Acquisition) in the year ended September 30, 1995. Excluding the $86.3 million
invested in the Peltor acquisition, the $6.6 million invested in the Eastern
acquisition and the escrow for the Eastern acquisition, net cash used by
investing activities would have been $9.3 million. The decrease was due to lower
levels of capital spending due to the completion of the major expenditures
related to the casting line at the Newark, Delaware facility and the worldwide
management information system. In fiscal 1992, 1993 and 1994 net cash used by
investing activities was $5.0 million, $8.9 million and $4.5 million
respectively. Spending was higher during fiscal 1993 principally due to the
consolidation of the Company's prescription eyewear facilities from four
locations into two locations.
 
Net cash provided by financing activities for the year ended September 30, 1996
was $95.5 million as compared to $164.5 million in the year ended September 30,
1995. In fiscal 1996 net cash provided by financing activities consisted
primarily of proceeds from the amended and restated Senior Bank Facilities which
were used to finance the acquisitions of Peltor and Eastern. In fiscal 1995 the
primary activity was the financing of the Formation Acquisition. The Formation
Acquisition was financed by the issuance of common and preferred stock totaling
$32.5 million, the issuance of Senior Subordinated Notes totaling $100.0
million, borrowings of $45.0 million in term loans, and borrowings of $3.1
million under the Senior Bank Facilities. The financings totaled $180.6 million
and were used to finance the cash paid for Cabot Safety Corporation of $169.2
million as well as financing costs of $11.4 million. Excluding these amounts,
net cash used by financing activities would have been $4.6 million for the year
ended September 30, 1995 as compared to $13.6 million for the year ended
September 30, 1994. This decrease was due to the increase in net cash used by
investing activities. In fiscal 1992 and 1993, net cash used by financing
activities was $25.2 million and $15.8 million, respectively. The decrease of
cash used by financing activities in 1994 was due to higher levels of capital
spending.
 
The Company has a substantial amount of indebtedness. The Company relies on
internally generated funds, and to the extent necessary, on borrowings under the
revolving credit facility available under the Senior Bank Facilities, which
provides for borrowings up to $25.0 million, subject to certain customary
drawing conditions, to meet its liquidity needs. In January 1996, the Company
borrowed $6.8 million under the Senior Bank Facilities to finance in part the
$7.8 million Eastern Acquisition purchase price. In May 1996, the Company
amended the Senior Bank Facilities to provide for an additional $86.0 million of
term loans to finance the Peltor acquisition. At September 30, 1996 the Company
had borrowed $5.1 million under the revolving credit facility. The company will
be borrowing under the revolver for the first several months of the next fiscal
year to support higher levels of inventory and receivables. These levels will
remain high until the difficulties associated with the conversion to the new
computer system are completely resolved and the improvements in production
planning are realized. The Company anticipates that operating cash flow will be
adequate to meet its debt service and capital expenditure requirements for the
next several years, although there can be no assurances that existing levels of
sales and normalized profitability, and therefore cash flow, will be maintained
in the future. Levels of sales and profitability will be impacted by service
levels, continued new product development, worldwide economic conditions and
competitive pressures. In addition, the Company may make additional acquisitions
in the future and would rely on internally generated funds and, to the extent
necessary, on borrowings under such revolving credit facility or from other
sources to finance such acquisitions. The Company's ability to borrow is limited
by covenants in the Senior Bank Facilities and the Subordinated Notes.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Shareholders of
  Aearo Corporation:
 
We have audited the accompanying balance sheets of Aearo Corporation (a Delaware
corporation) as of September 30, 1996 and 1995, and the related statements of
operations, stockholders' equity and cash flows for the year and the period then
ended, respectively. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.
 
We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Aearo Corporation as of
September 30, 1996 and 1995, and the results of its operations and its cash
flows for the year and the period then ended, respectively, in conformity with
generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               SEPTEMBER 30, 1996
 
(1)  BASIS OF PRESENTATION
 
For periods prior to July 11, 1995, the accompanying financial statements
represent the combined results and financial position of Aearo Company (formerly
Cabot Safety Corporation) and certain affiliates (the Predecessor) all of which
were wholly owned by Cabot Corporation (Cabot). On July 11, 1995, Cabot sold
substantially all of the assets and certain liabilities of the Predecessor to
Aearo Corporation (formerly Cabot Safety Holdings, Inc.) as described in Note 3
(Formation Acquisition). Financial statements for periods subsequent to July 11,
1995 represent the consolidated financial statements of Aearo Corporation and
subsidiaries (the Successor). References to the Company refer to the Predecessor
prior to the Formation Acquisition and the Successor postacquisition.
 
Separate financial statements of Aearo Company are not presented because they do
not provide any additional information from what is presented in the financial
statements of Aearo Corporation that would be meaningful to the holders of the
senior subordinated notes (see Note 8).
 
(2)  ORGANIZATION
 
The Company manufactures and sells personal safety equipment, as well as
energy-absorbing, vibration-damping and impact-absorbing products for industrial
noise control and environment enhancement. Included in personal safety equipment
are hearing protection, safety eyewear and respiratory equipment.
 
Prior to 1990, Cabot operated its domestic and foreign safety products and noise
control businesses in several subsidiaries and divisions. During 1990, Cabot
contributed the capital stock and net assets of its E-A-R division to the
Company. In April 1990, Cabot purchased the assets of AOSafety, the Safety
Products Division of American Optical Corporation.
 
(3)  FORMATION ACQUISITION AND FINANCING
 
Aearo Corporation was formed by Vestar Equity Partners, L.P. (Vestar) in June
1995 to effect the acquisition of substantially all of the assets and
liabilities of the Predecessor (the Formation Acquisition). The Predecessor was
wholly owned by Cabot prior to the Formation Acquisition. The Formation
Acquisition closed on July 11, 1995, when Aearo Corporation acquired
substantially all of the assets and certain liabilities of the Predecessor for
cash, preferred stock and a 42.5% common equity interest in Aearo Corporation,
as more fully described in Note 13. Aearo Corporation immediately contributed
the acquired assets and liabilities to Aearo Company, a wholly owned subsidiary
of Aearo Corporation, pursuant to an asset transfer agreement dated June 13,
1995. Aearo Corporation has no other material assets, liabilities or operations
other than those that result from its ownership of the common stock of Aearo
Company.

(a) The implied fair value of equity represents the implicit fair value of Aearo
    Corporation's equity based on the cash paid by Vestar and management for
    their equity interest in Aearo Corporation. The actual amount recorded for
    Aearo Corporation's equity was reduced by approximately $31.5 million to
    reflect predecessor basis for the portion of equity retained by Cabot.

The Formation Acquisition has been accounted for as a purchase transaction
effective as of July 11, 1995, in accordance with Accounting Principles Board
Opinion No. 16, Business Combinations, and EITF Issue No. 88-16, Basis in
Leveraged Buyout Transactions, and accordingly, the consolidated financial
statements for the periods subsequent to July 11, 1995 reflect the purchase
price, including transaction costs, allocated to tangible and intangible assets
acquired and liabilities assumed, based on a portion of their estimated fair
values as of July 11, 1995. The valuation of assets and liabilities acquired
reflect carryover basis for the percentage ownership retained by Cabot.

(4)  SIGNIFICANT ACCOUNTING POLICIES
 
The accompanying financial statements have been prepared in conformity with
generally accepted accounting principles. The significant accounting policies of
the Company are described below.
 
     PRINCIPLES OF COMBINATION AND CONSOLIDATION
 
The combined financial statements of the Company for the period ended July 11,
1995 and the year ended September 30, 1994 include Aearo Company and the results
of certain affiliates of the Company whose operations are partially or
exclusively related to the business of the Company. All significant transactions
and balances between affiliates have been eliminated. Transactions with Cabot
and its subsidiaries are reflected as intercompany balances.
 
The consolidated financial statements of the Company for the year ended
September 30, 1996 and period ended September 30, 1995 include the accounts of
Aearo Company and its subsidiaries. All significant intercompany balances and
transactions have been eliminated.

                               SEPTEMBER 30, 1996
 
     USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
     CASH EQUIVALENTS
 
For purposes of the statement of cash flows, the Company considers all time
deposits and short-term investments with an original maturity of three months or
less at time of purchase to be cash equivalents.
 
     FOREIGN CURRENCY TRANSLATION
 
Assets and liabilities of the Company's foreign operations are translated at
year-end exchange rates. Revenues and expenses are translated at the average
rate during the year. Foreign currency gains and losses arising from
transactions are reflected in net income. Balance sheet translation gains and
losses are reflected as a separate component of stockholders' equity.
 
     INVENTORIES
 
Inventories are stated at the lower of cost or market, cost being determined
using the first-in, first-out method.
 
     PROPERTY, PLANT AND EQUIPMENT
 
Property, plant and equipment are recorded at cost. Depreciation of property,
plant and equipment is calculated using the straight-line method based on
estimated economic useful lives. Expenditures for maintenance and repairs and
minor renewals are charged to expense.
 
Property, plant and equipment and their estimated useful lives consist of the
following:
 
<TABLE>
<CAPTION>
          ASSET CLASSIFICATION         ESTIMATED USEFUL LIFE            
        -----------------------     ---------------------------      
        <S>                         <C>                                 
        Buildings                           25-40 Years                 
        Leasehold improvements      Life of the lease or useful         
                                     life, whichever is shorter         
        Machinery and equipment              3-10 Years                 
        Furniture and fixtures               3-10 Years                 
</TABLE>
 
Upon the sale or retirement of assets, the cost and related accumulated
depreciation are removed from the financial statements, and any resultant gain
or loss is recognized.
 
     INCOME TAXES
 
For the year ended September 30, 1996, as in the period ended September 30,
1995, the Company will file a consolidated federal income tax return. The
Company filed a consolidated federal income tax return with Cabot for the period
ended July 11, 1995 and for the fiscal year ended September 30, 1994. The
provision for federal income taxes reflected in these financial statements for
which the Company filed consolidated returns with Cabot have been determined as
if the Company filed a separate federal income tax return.
 
Deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to reverse.

                               SEPTEMBER 30, 1996
 
     INTANGIBLE ASSETS
 
Intangible assets consist primarily of the costs of goodwill, patents and
trademarks purchased in business acquisitions. Intangible assets are amortized
on the straight-line basis over either 25 years or an estimated useful life,
whichever is shorter.
 
The Company accounts for long-lived and intangible assets in accordance with
SFAS No. 121, Accounting for the Impairment of Long-lived Assets and for
Long-lived Assets to be Disposed of. The Company continually reviews its
intangible assets for events or changes in circumstances which might indicate
the carrying amount of the assets may not be recoverable. The Company assesses
the recoverability of the assets by determining whether the amortization of such
intangibles over their remaining lives can be recovered through projected
undiscounted future cash flows. The amount of impairment, if any, is measured
based on projected discounted future cash flows using a discount rate reflecting
the Company's average cost of funds. At September 30, 1996, no such impairment
of assets was indicated.
 
A summary of the estimated lives by major category of intangible assets at
September 30, 1996 is as follows:
 
<TABLE>
        <S>                            <C>
        Goodwill...................                          25 Years
        Patents....................                          17 Years
        Non-compete agreement......    Life of agreement (4.5 years at September 30, 1996)
        Trademarks, Tradenames and
          Other....................                Various from 15 to 25 Years
        </TABLE>
         
     DEFERRED FINANCING COSTS
 
Deferred financing costs are stated at cost as a component of other assets and
amortized over the life of the related debt using the effective interest method.
Amortization of deferred financing costs is included in interest expense.
 
     FAIR VALUE OF FINANCIAL INSTRUMENTS
 
In accordance with the requirements of Statement of Financial Accounting
Standards (SFAS) No. 107. Disclosures About Fair Value of Financial Instruments,
the Company has determined the estimated fair value of its financial instruments
using appropriate market information and valuation methodologies. Considerable
judgment is required to develop the estimates of fair value; thus, the estimates
are not necessarily indicative of the amounts that could be realized in a
current market exchange. The Company's financial instruments consist of cash,
accounts receivable, accounts payable, senior subordinated notes and bank debt.
The carrying value of these assets and liabilities is a reasonable estimate of
their fair market value at September 30, 1996.
 
     NET INCOME (LOSS) PER COMMON SHARE
 
Net income (loss) per common share has been computed by dividing earnings
applicable to common shareholders for the period by the weighted average number
of common shares outstanding during the period.
 
     STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123 -- ACCOUNTING FOR
STOCK-BASED COMPENSATION
 
In December 1995, the Financial Accounting Standards Board issued SFAS No. 123,
Accounting for Stock-Based Compensation, which is to become effective for fiscal
years beginning after December 15, 1995. SFAS No. 123 requires employee
stock-based compensation to be either recorded or disclosed at its fair value.
Management intends to continue to account for employee stock-based compensation
under Accounting Principles Board Opinion No. 25 and will not adopt the new
accounting provision for employee stock-based

Revolving Credit and Term Loans
 
In July 1995, Aearo Company entered into a credit agreement (the Agreement) that
provides for secured borrowings from a syndicate of lenders consisting of (i) a
five-year revolving credit facility providing for up to $25.0 million in
revolving loans, $5.0 million of which may be used for letters of credit (the
Revolving Credit Facility) and (ii) a term loan facility providing for $45.0
million in term loans, consisting of a $28.5 million U.S. term loan, a $4.5
million term loan designated in Canadian dollars and a $12.0 million term loan
designated in Sterling (collectively, the Term Loans).
 
Amounts outstanding under the Term Loans accrued interest, payable quarterly in
arrears, at a rate equal to the sum of the Eurodollar rate plus 2%. At September
30, 1995, the rates on the Term Loans were 7.9% for the U.S. term loan, 8.4% for
the Canadian term loan and 8.8% for the Sterling term loan. The weighted average
interest rates paid during 1995 were 7.9%, 8.5% and 8.7% for the US term loan,
Canadian term loan and Sterling term loan, respectively.

                               SEPTEMBER 30, 1996
 
Principal on the Term Loans is being paid in quarterly installments through
March 31, 2000 on the U.S. and Sterling term loans, and the principal on the
Canadian term loan is due on July 11, 2000. Aearo Corporation had the option to
convert all or a portion of the outstanding principal amount of Term Loans into
either a Eurodollar rate or a reference-rate loan. The amount outstanding at
September 30, 1995 on the Term Loans was $43.8 million.
 
Under the Revolving Credit Facility, only the U.S. and UK entities were
permitted to borrow funds. Interest on borrowings under the Revolving Credit
Facility is payable in arrears at a rate equal to either the sum of .75% plus

Company had $3.8 million outstanding on the Revolving Credit Facility. During
the period from July 11, 1995 to September 30, 1995, the maximum amount
outstanding under the Revolving Credit Facility was $5.5 million with the
average amount being $2.7 million. The weighted average interest rate paid
during 1995 was 9.5%.
 
The Revolving Credit Facility also required Aearo Company to pay a commitment
fee on the average daily aggregate unutilized portion of the Revolving Credit
Facility at a rate of .50% per annum. The fee is payable quarterly in arrears as
well as a commission on trade and standby letters of credit of 2% per annum of
the amount to be drawn under the Agreement. Amount outstanding under the
revolving credit were due on July 11, 2000.
 
On May 30, 1996, Aearo Company and the Syndicated Lenders amended and restated
the Senior Bank Facility. The amended and restated Credit Facility consists of
(a) a secured term loan facility consisting of A and B term loans providing for
up to $90 million of A term loans and $50 million of B term loans (collectively,
the "Term Loans"); a portion of the A term loans is denominated in an equivalent
amount of foreign currencies and (b) a secured revolving credit facility (the
"Revolving Credit Facility") providing for up to $25 million of revolving loans,
a portion of which may be denominated in foreign currencies, for general
corporate purposes and, as to $15 million thereof, to finance permitted
acquisitions. As part of the Revolving Credit Facility, the Senior Bank
Facilities provide for the issuance of letters of credit in an aggregate face
amount of up to $5 million. The Term Loans will amortize quarterly over a
seven-year period. Amounts repaid or prepaid in respect of the Term Loans may
not be reborrowed. Loans and letters of credit under the Revolving Credit
Facility will be available at any time prior to the maturity date of the Senior
Bank Facilities as amended and restated. The amount outstanding at September 30,
1996 on the Term Loans was $139.4 million.
 
At the Company's option, the interest rates per annum applicable to the Senior
Bank Facilities are either an adjusted rate based on the London Interbank
Offered Rate plus a margin of 2.25% in the case of A Term Loans and Revolving
Loans and 2.75% in the case of B Term Loans, or the Base Rate, as defined plus a
margin of 1.00% in the case of A Term Loans and Revolving Loans and 1.50% in the
case of B Term Loans. The Base Rate is the higher of Bankers Trust Company's
announced prime lending rate and the Overnight Federal Funds rate plus 0.50%.
The Company must pay certain fees in connection with the Senior Bank Facility,
including a commitment fee ranging from 0.375% to 0.50% on the undrawn portion
of the commitments in respect of the Revolving Credit Facility based upon the
Company's leverage ratio, and fees relating to the issuance of letters of
credit.

Loan, 5.4% for the US DEM Term A Loan, 8.1% for the US Sterling Term A Loan,
6.4% for the Canadian Term A Loan, 8.1% for the Sterling Term A Loan and 8.3%
for the US Term B Loan. During the period of May 30, 1996 to September 30, 1996
the weighted average interest rates paid were 7.7%, 5.6%, 8.1%, 6.8%, 8.1% and
8.2% for the US Term A Loan, for the US DEM Term A Loan, for the US Sterling
Term A Loan, for the Canadian Term A Loan, for the Sterling Term A Loan and for

(11)  EMPLOYEE BENEFIT PLANS
 
The Company has two noncontributory defined benefit pension plans, the Aearo
Company Employees Retirement Account Plan (the Aearo Plan), which is a cash
balance plan, and the E-A-R Specialty Composites Division of Aearo Company
Non-Union Employees Retirement Plan (the Specialty Composites Plan). Benefits
provided under these plans are primarily based on years of service and the
employee's compensation.
 
The Aearo Plan, effective May 1, 1990, covers most employees in the United
States and is funded quarterly based on actuarial and economic assumptions
designed to achieve adequate funding of projected benefit obligations. Plan
assets are invested in a portfolio consisting primarily of debt and equity
securities. The

to a maximum of 2% of the employee's pay. The costs to the Company for this Plan
were $425,000, $100,000, $345,000 and $365,000 for the year ended September 30,
1996, the periods ended September 30, 1995 and July 11, 1995 and the year ended

The Company has a defined contribution savings plan for U.K. employees, under
which eligible employees are allowed to contribute up to 15% of their
compensation. The Company contributes 5% of pay for all eligible employees and
additional amounts equal to 40% of the employee's contribution to a maximum of

Postretirement Benefits
 
The Company does not provide defined benefit postretirement plans for retirees
after age 65. All employees who elect early retirement at age 62 or older are
eligible to receive life insurance coverage that terminates on their 65th
birthday. In addition, employees who were age 55 or older with 10 years of
service as of April 1, 1990 are eligible to receive limited health care and life
insurance coverage for themselves and their eligible dependents upon early
retirement at age 62 or older. These coverages terminate on the 65th birthday of
the retiree or his or her spouse. The health care benefit is a fixed dollar
contribution and the life insurance benefit is a fixed coverage amount.
 
As of September 30, 1996 and 1995, the accrued postretirement benefit cost was
$168,000 and $215,000, respectively.
 
(12)  RELATED PARTY TRANSACTIONS
 
An annual management fee, which is to be shared by Cabot and Vestar, will be
paid in aggregate amounts with respect to each fiscal year equal to the greater
of (i) $400,000 or (ii) 1.25% of the consolidated net income of the Company and
its subsidiaries before cash interest, taxes, depreciation and amortization for
such fiscal year. This annual management fee is shared by Cabot and Vestar based
on their relative equity ownership of the Company.
 
The Company and Cabot have entered into an arrangement relating to certain
respirator claims asserted after the Acquisition whereby, so long as the Company
pays to Cabot an annual fee of $400,000, Cabot will retain responsibility and
liability for, and indemnify the Company against, certain legal claims alleged
to arise out of the use of respirators manufactured prior to July 1995. The
Company has the right to discontinue the payment of such annual fee at any time,
in which case the Company will assume responsibility for and indemnify Cabot
with respect to such claims.
 
Certain management investors (Management Investors) borrowed $934,000 to fund a
portion of the purchase price of Common Stock to be issued to such management
investors in connection with the Acquisition. Such loans are secured by Common
Stock, purchased with the proceeds thereof, are expected to have a term of
approximately 10 years, will bear interest at an annual rate determined pursuant
to Section 7872(f)(2) of the 1986 IRC, and will be subject to mandatory
prepayment in the event the employment of such management investors terminates.
 
Prior to the Formation Acquisition, the Company engaged in various transactions
with Cabot and its affiliates that are characteristic of a combined group under
common control. Cabot had historically provided the Company with various
financial and administrative functions and services, including the continued
participation of the Company in certain insurance policies maintained by Cabot,
for which the Company is charged associated direct costs and expenses. In
addition, certain indirect administrative costs were allocated to the various
business units of Cabot, including the Company, principally based on a formula
that considered

such proportionate variables as revenue, payroll and property balances.
Administrative costs of doing business on a stand-alone basis may have been
significantly different. Cabot also provided financing and cash management for
the Company through a centralized treasury system. Operating expenses, as
described above, were $1,728,000 and $1,832,000 for the period ended July 11,
1995 and the year ended September 30, 1994, respectively.

The valuation allowance at September 30, 1996 and 1995 relates to the
uncertainty of realizing the tax benefits of reversing temporary differences and
net operating loss carryforwards. Of this valuation allowance, approximately
$10,655 will be used to reduce goodwill or other intangibles related to the
purchase if the benefits are realized.
 
The change in valuation allowance includes a decrease of $2,135,000 related to
the realization of certain tax assets related to the Formation Acquisition. This
amount has been used to reduce goodwill.
 
(14)  STOCKHOLDERS' EQUITY
 
Stock Ownership and Stockholders' Agreement
 
Prior to the Formation Acquisition, Cabot owned 100% of the outstanding shares
of the Company. Currently, (i) Cabot owns 42.5% of Common Stock and 50% of
Redeemable Preferred Stock, (ii) Vestar owns 42.5% of Common Stock and 50% of
Redeemable Preferred Stock and (iii) the Management Investors own 15% of Common
Stock. Vestar, Cabot and Management entered into a stockholders' agreement (the
Stockholders' Agreement) as of the Formation Acquisition date. The Stockholders'
Agreement contains stock transfer restrictions, as well as provisions granting
certain tag-along rights, drag-along rights, registration rights and
participation rights.
 
Common and Preferred Stock
 
To finance a portion of the Formation Acquisition, Aearo Corporation issued
8,000,000 (3,400,000 each to Vestar and Cabot and 1,200,000 to Management
Investors) shares of Common Stock and 45,000 shares of Redeemable Preferred
Stock (22,500 each to Vestar and Cabot). Management Investors received a loan
from the Company in the amount of $934,000 to fund a portion of its cost of the
Acquisition. This amount has been reflected as a reduction to additional paid-in
capital related to the issuance of Common Stock.
 
The Redeemable Preferred Stock is cumulative redeemable $.01 par value stock.
Dividends accrue whether or not dividends are declared or funds are available at
an annual rate of 12.5%, compounded daily. Accrued dividends may be paid in cash
or in additional shares of preferred stock. Shares are redeemable for cash at
any time, subject to certain exceptions, at the option of Holdings at a
redemption price equal to the actual or implied purchase price ($45 million)
plus a redemption payment based on the dividend rate.

latter purpose. Additionally, Aearo Corporation may pay dividends on its
preferred stock in additional shares of preferred stock.

(15)  COMMITMENTS AND CONTINGENCIES
 
Compensation Plans
 
The Company provides performance-based compensation awards to executive officers
and key employees for achievement during each year as part of an annual bonus
plan. Such compensation awards are a function of individual performance and
consolidated operating results. Business unit performance is also a factor used
in determining compensation awards with respect to key employees who are not
executive officers. The Company also has an overall incentive plan which
provides performance-based compensation awards to all employees based on
consolidated operating results.
 
Upon consummation of the Formation Acquisition, the Company adopted a
supplemental severance pay plan providing certain executive officers and key
employees with salary continuation, based on years of service, in the event of
an eligible termination. The plan provides for one month's base pay for each
full year of service with a minimum amount payable of three months and a maximum
amount payable of 12 months.
 
Lease Commitments
 
<TABLE>
The Company leases certain transportation vehicles, warehouse facilities, office
space, and machinery and equipment under cancelable and noncancelable leases,
most of which expire within 10 years and may be renewed by the Company. Rent
expense under such arrangements totaled $4,268,000, $2,805,000, $768,000 and
$4,395,000, for the year ended September 30, 1994, the periods ended July 11,
1995 and September 30, 1995 and the year ended September 30, 1996, respectively.
Future minimum rental commitments under noncancelable leases in effect at
September 30, 1996 are as follows (dollars in thousands):

</TABLE>
 
Contingencies
 
The Company is a defendant in various lawsuits and administrative proceedings
which are being handled in the ordinary course of business. In the opinion of
management of the Company, these suits and claims should not result in final
judgments or settlements which, in the aggregate, would have a material adverse
effect on the Company's financial condition or results of operations.
 
During fiscal 1995, the Company became aware that its French subsidiary has been
delinquent in the remittance of value-added tax payments to the French
government. The Company believes that any required tax payments and attendant
penalties will not have a material adverse effect on the Company's financial
condition or results of operations.
 
(16)  ACQUISITIONS
 
On May 30, 1996, the Company acquired Peltor Holding AB (the Acquisition) for
approximately $85.6 million. The Acquisition has been accounted for as a
purchase transaction in accordance with Accounting Principles Board Opinion No.
16, and accordingly, the consolidated financial statements for the periods
subsequent to May 30, 1996 reflect the purchase price, including transaction
costs, allocated to tangible and intangible assets acquired and liabilities
assumed, based on their estimated fair values as of May 30, 1996.

(1) The options will vest and become exercisable upon the earlier of: (i) the
    date on which certain financial performance benchmarks (which depend in part
    on the future market value of the Aearo Common Stock) are achieved by the
    Company and (ii) the tenth anniversary of the date of grant (June 26, 2006).
    All options are subject to the employee's continued employment and terminate
    ten years after the grant date, subject to earlier termination in accordance
    with the Company's Executive Stock Option Plan and the applicable option
    agreement.
 
(2) This column shows the hypothetical gain or "option spreads" of the options
    granted based on both the fair market value of the Aearo Common Stock for
    financial reporting purposes and assumed annual compound stock appreciation
    rates of 5% and 10% over the term of the options. The 5% and 10% assumed
    rates of appreciation are mandated by the rules of the Securities and
    Exchange Commission and do not represent the Company's estimate or
    projection of future Aearo Common Stock prices. The gains shown are net of
    the option exercise price, but do not include deductions for taxes or other
    expenses associated with the exercise of the option or the sale of the
    underlying shares, or reflect nontransferability, vesting or termination
    provisions. The actual gains, if any, on the exercises of stock options will
    depend on the actual future performance of the Aearo Common Stock.

(1) There was no public market for the Aearo Common Stock as of September 30,

    assumed fair market value of $600 per share.
</TABLE> 

DIRECTOR COMPENSATION
 
Directors (other than two Directors unaffiliated with Cabot or Vestar (the
"Outside Directors")) serve without compensation (other than reimbursement of
expenses) in connection with rendering services as such. The Outside Directors
receive $10,000 annually for their service as Directors and an additional $2,500
per meeting, plus reimbursement of expenses. In connection with their
appointment, Outside Directors were given the opportunity to purchase a limited
amount of shares of Aearo Common Stock; during fiscal 1996, John W. Priesing,
one of the Outside Directors, purchased 100 shares at a price of $200 per share
and Samuel L. Hayes, III, the other Outside Director, purchased 100 shares at a
price of $600 per share. In connection with such purchases Messrs. Priesing and
Hayes became parties to the Stockholders' Agreement. See Item 13, "Certain
Relationships and Related Transactions -- Stock Ownership and Stockholders'
Agreement."
 
EMPLOYEE STOCK AND OTHER BENEFIT PLANS
 
STOCK PURCHASE PLAN.  In connection with the Formation Acquisition, the Company
adopted the Cabot Safety Holdings Corporation 1995 Stock Purchase Plan, as
amended and restated (the "Stock Purchase Plan"), in order to encourage
ownership of Aearo Common Stock by selected officers and employees and
independent directors of the Company. Under the Stock Purchase Plan, the
Company's executive officers and other senior members of management were given
the opportunity to purchase from the Company, in the aggregate, up to 15,000
shares of Aearo Common Stock. An initial 14,100 shares, comprising a portion of
the newly issued shares of Aearo Common Stock offered and sold in connection
with the Formation Acquisition, were purchased by Management Investors
simultaneously with the Formation Acquisition at a price of $200 per share, the
same price paid by Vestar and Cabot, for an aggregate consideration of
$2,820,000 (including 4,950 shares by Mr. Curtin, 2,250 shares by Mr. Young,
1,050 shares by Mr. O'Connor, 1,500 shares by Mr. Carey and 1,050 shares by Mr.
Hall). The purchase price was paid in part ($2,066,000) in cash and in part
($934,000) through the delivery of promissory notes with a term ranging from 5
to 10 years, bearing interest at the annual rate of 7% and secured by a pledge
of the purchased shares. See Item 13, "Certain Relationships and Related
Transactions -- Other Relationships -- Management Loans." Of the remaining 900
shares of Aearo Common Stock offered through the Stock Purchase Plan, 800 shares
were purchased by W. Larry Lewis, the Company's Director of Operations, on
February 15, 1996 at a price of $200 per share paid in cash and 100 shares were
purchased by John W. Priesing, an Outside Director, on April 14, 1996 at a price
of $200 per share paid in cash. Mark H. Hague, the Company's Vice President of
Operations, effective November 11, 1996, has agreed to purchase 1,050 shares at
a price of $600 per share payable in cash. Of the 800 shares sold to Mr. Lewis,
640 shares have been repurchased by the Company. As a result of certain
repurchases, without giving effect to Mr. Hague's purchase, 1,440 shares of
Aearo Common Stock are available for purchase under the Stock Purchase Plan.
Upon his election as a director of the Company on May 27, 1996, Samuel L. Hayes,
III, an Outside Director, was offered the opportunity to
 
                                       51
<PAGE>   54
 
purchase 100 shares of Aearo Common Stock at a price of $600 per share, which he
paid in cash on June 25, 1996, on terms substantially identical to those of the
Stock Purchase Plan.
 
Aearo Common Stock acquired under the Stock Purchase Plan is subject to
forfeiture through various puts and calls. In the event of death, permanent
disability or retirement, which retirement occurs at age 65 or older with at
least 3 years of service, such stock may be put to the Company by the holder at
fair market value and the Company has a call on such stock at the same price. In
the event of termination for cause, the Company has a call at the lesser of
initial cost and fair market value. In the event of termination by the Company
other than for cause and in the case of voluntary resignation, the Company has a
call (i) with respect to a percentage of such stock equal to the number of years
elapsed since the Formation Acquisition multiplied by 20% at fair market value,
and (ii) with respect to the remainder of such stock at the lesser of initial
cost and fair market value. Shares repurchased by the Company are held in
reserve, and may be issued to existing and future employees or non-employee
directors. These puts and calls expire (i) on the date on which certain
financial performance benchmarks (which, following an initial public offering of
the Aearo Common Stock, depend in part on the future market value of the Aearo
Common Stock) are achieved by the Company or (ii) the fifth anniversary of the
Formation Acquisition. Each Management Investor is also required to be a party
to the Stockholders' Agreement. See Item 13, "Certain Relationships and Related
Transactions -- Stockholders' Agreement."
 
EXECUTIVE STOCK OPTION PLAN.  In June 1996, the Company's Board of Directors
adopted and the stockholders subsequently approved the Executive Stock Option
Plan (the "Executive Plan") under which 5,000 shares of Aearo Common Stock have
been reserved for issuance. Non-qualified options to acquire all 5,000 shares at
a price of $600 per share were granted on June 26, 1996 to officers and key
employees of the Company; of these options, 2,062 in the aggregate were granted
to executive officers, including Mr. Curtin (812 options), Mr. Young (437
options), Mr. O'Connor (250 options), Mr. Hall (250 options) and Mr. Carey (313
options).
 
The Executive Plan is administered by a committee of the Board of Directors
consisting of all non-employee directors. As of September 30, 1996 no such
options were exercisable and no options remained available for future grant
under the Executive Plan. The options will vest and become exercisable upon the
earlier of: (i) the date on which certain financial performance benchmarks
(which depend in part on the future market value of the Aearo Common Stock) are
achieved by the Company and (ii) the tenth anniversary of the date of grant. The
option term is 10 years; provided, however, that unexercised options expire
earlier in certain instances of termination of employment of the option holder
and may expire in the event of a merger or liquidation of the Company or a sale
of substantially all the assets of the Company. Aearo Common Stock acquired upon
exercise of options granted under the Executive Plan is subject to the same
restrictions, including puts and calls and drag-along rights as Aearo Common
Stock acquired under the Stock Purchase Plan. See "Stock Purchase Plan."
 
ANNUAL BONUS.  The Company provides performance-based compensation awards to
executive officers and key employees for achievement during each year as part of
an annual bonus plan. Such compensation awards are a function of individual
performance and consolidated corporate results. Business unit performance also
is a factor in determining compensation awards with respect to key employees who
are not executive officers. The specified qualitative and quantitative criteria
employed by the Board of Directors of the Company in determining bonus awards
varies for each individual and from year to year.
 
SUPPLEMENTAL SEVERANCE PAY PLAN.  The Company has adopted a supplemental
severance pay plan providing certain executive officers and key employees with
salary continuation in the event of an eligible termination based on years of
service. The plan provides for one month's base pay for each full year of
service with a minimum amount payable of three months and a maximum amount
payable of twelve months.
 
SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN.  The Company has adopted a supplemental
executive retirement plan, which is a non-qualified plan under the Code, and
which provides unfunded deferred compensation benefits to certain executive
officers and key employees. Pursuant to the plan, participants are credited
annually with amounts representing 4% of compensation in excess of that amount
of compensation subject to social security taxes.
 
                                       52
<PAGE>   55
 
401(k) PLAN.  The Company has adopted a savings plan (the "Saving Plan"), which
is qualified under Section 401(a) and 401(k) of the Code. All regular employees
of the Company in the United States are eligible to participate in the Savings
Plan after six months of service. For each employee who elects to participate in
the Savings Plan and makes a contribution thereto, the Company will make a
matching contribution. The Company matches 40.0% of the first 5.0% of
compensation contributed. The maximum contribution for any participant for any
year is 15.0% of such participant's eligible compensation. Contributions to the
Savings Plan will be invested, as the employee directs, in a fixed income fund,
balanced fund, or equity fund.
 
PENSION PLAN.  The Company has adopted a cash balance plan. Under such plan, the
Company will provide participants with annual credits of 4% of eligible
compensation. All balances in the accounts of participants will be credited with
interest based on the one-year U.S. Treasury bill rate. At retirement,
participants eligible for benefits may receive the balance standing in their
account in a lump sum or as a monthly pension having equivalent actuarial value.
The following table sets forth, for the Named Executive Officers, the estimated
annual benefits payable upon retirement at normal retirement age, assuming in
each case that such officer elects payment over time rather than in a lump sum:

EMPLOYMENT AGREEMENTS
 
Each of Mr. Leif Palmaer, who has been the President of Peltor since 1981, and
Mr. Leif Anderzon, who has been the Executive Vice President of Peltor since
1981, has an employment agreement with Peltor, which was in existence when the
Company acquired Peltor on May 30, 1996. Each agreement will terminate on
December 31, 1999, and is renewable for additional twelve-month periods at the
election of the parties. During the term of the agreement, each of Mr. Palmaer
and Mr. Anderzon will be paid 900,000 Swedish Krona (approximately $138,500)
annually and will devote substantially all of his professional time and efforts
to Peltor. Their employment may be terminated at any time for cause. During the
term of employment and for two years thereafter, each of Mr. Palmaer and Mr.
Anderzon will be bound by confidentiality and non-competition restrictions.
Messrs. Palmaer and Anderzon have advised the Company of their intent to retire
in July 1997.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
The Company does not have a compensation committee. Since July 1995, all
executive officer compensation decisions have been made by the full Board of
Directors of the Company, with Messrs. Curtin and Young abstaining with respect
to decisions affecting their own compensation. Mr. Curtin, one of the directors
of the Company, is the Chairman of the Board and Chief Executive Officer of the
Company. Mr. Young, one of the directors of the Company, is the President and
Chief Operating Officer of the Company. On July 11, 1995, Mr. Curtin acquired
4,950 shares of Aearo Common Stock under the Stock Purchase Plan at a price of
$990,000. On July 11, 1995, Mr. Young acquired 2,250 shares of Aearo Common
Stock under the Stock Purchase Plan at a price of $450,000 and as of September
30, 1996 was indebted to the Company in the

     Stock held by Management Investors who are not executive officers.
 
ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
THE ASSET TRANSFER AGREEMENT
 
The Company is a party to an asset transfer agreement dated as of June 13, 1995
with Cabot and certain of its subsidiaries (including Old Cabot Safety
Corporation) (the "Asset Transfer Agreement") entered into in connection with
the Formation Acquisition. The Asset Transfer Agreement contains customary
representations, warranties and covenants. Cabot and certain of its
subsidiaries, on the one hand, and Aearo and the Subsidiary on the other, have
also agreed to indemnify and hold each other and their affiliates harmless
against certain breaches of representations or covenants and certain other
liabilities.
 
The Company has the right to pay an annual fee of $400,000 to Old Cabot Safety
Corporation, and has elected to make this payment, with the result that Old
Cabot Safety Corporation will retain responsibility and liability for, and
indemnify the Company against, certain legal claims alleged to arise out of the
use of respirators manufactured prior to June 1995. The Company has the right to
discontinue the payment of such annual fee at any time, in which case the
Company will assume responsibility for and indemnify Cabot and Old Cabot Safety
Corporation with respect to such claims.
 
The amount of the aggregate consideration payable under the Asset Transfer
Agreement was subject to adjustment based on a balance sheet that was prepared
after the closing of the Formation Acquisition to reflect the value of the net
operating assets gained in the Formation Acquisition. Since the volume of such
net operating assets exceeded $72.0 million, the Subsidiary was required to make
a payment to a subsidiary of Cabot in the amount of approximately $1.1 million,
which amount was paid during fiscal 1996.
 
STOCK OWNERSHIP AND STOCKHOLDERS' AGREEMENT
 
Prior to the Formation Acquisition, Cabot owned 100% of the outstanding shares
of the Subsidiary, which enabled Cabot to elect all of the directors of the
Subsidiary. After the consummation of the Formation Acquisition, (i) Cabot
indirectly owns 42.5% of the Aearo Common Stock outstanding and 50% of the Aearo
Preferred Stock outstanding, (ii) Vestar owns 42.5% of the Aearo Common Stock
outstanding and 50% of the Aearo Preferred Stock outstanding and (iii) the
Management Investors and Outside Directors own 15.0% of the Aearo Common Stock
outstanding. Cabot, Vestar and the Management Investors (the "Stockholders") own
100% of the outstanding shares of Aearo Common Stock and will elect all of the
directors of Aearo and
 
                                       55
<PAGE>   58
 
determine the outcome of all matters requiring stockholder approval, including
mergers, consolidations and the sale of all or substantially all of the assets
of Aearo, and to prevent or cause a change in control of Aearo, in each case
subject to such restrictions, limitations and conditions as may be imposed under
the Stockholders' Agreement. There can be no assurance as to how long any of
Cabot, Vestar or the Management Investors will hold their shares of Aearo Common
Stock.
 
Cabot, Vestar, the Management Investors and the Outside Directors have entered
into the Stockholders' Agreement which provides for, among other things, the
matters described below.
 
ELECTION AND REMOVAL OF DIRECTORS.  The Stockholders' Agreement provides that
the Board of Directors of the Company shall consist of nine members. The parties
agreed to vote all shares of Aearo Common Stock owned or controlled by them so
as to elect as members of the Board of Directors persons designated as follows:
(i) Vestar designates three directors so long as the Vestar Relative Percentage
(as defined below) is at least 75% or Vestar and its affiliates beneficially own
on a fully diluted basis at least 21,250 shares of Aearo Common Stock (50% of
the shares of Aearo Common Stock acquired by them in the Formation Acquisition),
(ii) Cabot may designate two directors so long as the Cabot Relative Percentage
(as defined below) is at least 75% or Cabot and its affiliates own beneficially
on a fully diluted basis at least 21,250 shares of Aearo Common Stock (50% of
the shares of Aearo Common Stock acquired by them in the Formation Acquisition),
(iii) Vestar may designate two additional directors who are not partners,
officers or employees of any of Vestar or its affiliates so long as the Vestar
Relative Percentage is as least 75% or Vestar and its affiliates beneficially
own at least 31,875 shares of Aearo Common Stock (75% of the shares of Aearo
Common Stock acquired by them in the Formation Acquisition), provided that
Vestar must notify Cabot in writing in advance of the identities of these
director nominees and obtain Cabot's approval thereof, which may not be
unreasonably withheld, and (iv) the Management Investors may designate two
directors so long as the Management Investors together own beneficially on a
fully diluted basis at least 3,750 shares of Aearo Common Stock (25% of the
shares of Aearo Common Stock acquired by all Management Investors in the
Formation Acquisition), provided that the two designees of the Management
Investors must be the principal executive officer and the principal operating
officer of the Company. The foregoing provisions relating to the election of
directors terminate in the event that both Cabot and its affiliates, on the one
hand, and Vestar and its affiliates, on the other hand, own on a fully diluted
basis fewer than 4,250 shares of Aearo Common Stock (10% of the shares of Aearo
Common Stock acquired by them in the Formation Acquisition). The term "Vestar
Relative Percentage" means a percentage reflecting (a)(i) $31 million plus (ii)
the amount paid for capital stock of Aearo by Vestar and its Affiliates after
the Formation Acquisition less (iii) the value (based on price per share) of all
shares of Aearo Common Stock and Aearo Preferred Stock acquired by Vestar and
its affiliates in the Formation Transaction and no longer held by them, less
(iv) the value of all shares of the Aearo Common Stock and Aearo Preferred Stock
acquired by Vestar and its affiliates after the Formation Acquisition and no
longer held by them, as a percentage of (b) the amount calculated pursuant to
clause (a) for Cabot and its affiliates for such date. The term "Cabot Relative
Percentage" has a correlative meaning focused on Cabot's remaining investment in
Aearo capital stock relative to Vestar's.
 
Messrs. Alpert, O'Connell and Nagle were designated by Vestar as described in
clause (i) above, Mr. Gilson and Ms. Hanratty were designated by Cabot as
described in clause (ii) above, Messrs. Priesing and Hayes were designated by
Vestar as described in clause (iii) above and Messrs. Curtin and Young were
designated by the Management Investors as described in clause (iv) above. All
directors can be removed, with or without cause, and replaced by the
stockholders who have the right to designate them.
 
TAG-ALONG RIGHTS.  So long as a public offering of Aearo Common Stock shall not
have occurred and subject to certain exceptions, with respect to any proposed
transfer of Aearo Common Stock or Aearo Preferred Stock by Vestar, other than
transfers to affiliates, each other stockholder will have the right to require
that the proposed transferee purchase a certain percentage of the shares owned
by such stockholder at the same price and upon the same terms and conditions.
 
DRAG-ALONG RIGHTS.  The Stockholders' Agreement provides that, so long as Vestar
and its affiliates beneficially own at least 21,250 shares of Aearo Common Stock
(50% of the shares of Aearo Common Stock acquired by them in the Formation
Acquisition) or the Vestar Relative Percentage is at least 75%, if Vestar
 
                                       56
<PAGE>   59
 
receives an offer from a third party to purchase all but not less than all
outstanding shares of Aearo Common Stock and Aearo Preferred Stock and such
offer is accepted by Vestar, then each party to the Stockholders' Agreement will
transfer all shares of Aearo Common Stock and Aearo Preferred Stock owned or
controlled by such party on the terms of the offer so accepted by Vestar,
provided that all such transfers occur on substantially identical terms and the
number of shares to be acquired by the third party after giving effect to all
such transfers would be sufficient under the certificate of incorporation and
by-laws of the Company, any applicable agreements and applicable law to permit
such third party to eliminate all remaining minority interests through a merger
opposed by such minority interests. These so-called "drag-along" rights do not
apply to sales in a public offering or to stock that has been sold by a party to
the Stockholders' Agreement in a public offering or pursuant to Rule 144.
 
If Vestar intends to transfer Aearo Common Stock to a third party in any
transaction in which these drag-along rights are invoked, Vestar must give Cabot
30 days' advance written notice and, at the request of Cabot must discuss the
possibility of Cabot, in lieu of the third party, acquiring such Aearo Common
Stock, provided that this provision does not obligate Cabot to purchase such
Aearo Common Stock or Vestar to sell such Aearo Common Stock either to Cabot or
to the third party.
 
OTHER VOTING MATTERS.  So long as the drag-along rights are in effect, the
parties to the Stockholders' Agreement are obligated to vote all shares of Aearo
Common Stock owned or controlled by them to ratify, approve and adopt the
following actions to the extent that they are adopted and approved by the Board
of Directors: (i) any merger or consolidation involving the Company that is, in
substance, an acquisition of another company by the Company or a sale of the
Company and in either case does not affect in any way the relative rights of
Cabot and Vestar or result in any benefit to Vestar other than the benefits to
it as a stockholder of the Company equal to the benefits received by other
stockholders, share for share, and (ii) any amendment to the certificate of
incorporation of the Company whereby such amendment does not adversely affect
such stockholder in a manner different from that in which any other stockholder
is affected. In addition, so long as the voting agreements providing for the
election of directors remain in effect, the parties to the Stockholders'
Agreement agreed not to vote to approve, ratify or adopt any amendment to the
by-laws of the Company unless such amendment is expressly authorized by the
Stockholders' Agreement or recommended by the Board of Directors.
 
TRANSFERS OF COMMON STOCK.  Subject to certain limitations, transfers of Aearo
Common Stock and Aearo Preferred Stock by parties to the Stockholders' Agreement
are restricted unless the transferee agrees to become a party to, and be bound
by, the Stockholders' Agreement, provided that such restrictions do not apply to
sales in a public offering or pursuant to Rule 144. In addition, subject to
certain limitations, Cabot and the Management investors agreed not to transfer
their shares of Aearo Common Stock or Aearo Preferred Stock without the prior
written consent of Vestar. Under certain circumstances, the transfer of Aearo
Common Stock or Aearo Preferred Stock by Vestar, Cabot and their affiliates is
permitted.
 
PARTICIPATION RIGHTS.  Under certain circumstances, if Aearo proposes to issue
any capital stock to Vestar, Cabot or any of their respective affiliates, each
other stockholder shall have the opportunity to purchase such capital stock on a
pro rata basis.
 
APPROVAL OF AFFILIATE TRANSACTIONS.  The Stockholders' Agreement provides that
the Company shall not, and shall cause its subsidiaries not to, enter into any
transaction with any affiliate of the Company unless such transaction (i) is on
fair and reasonable terms no less favorable to the Company or such subsidiary
than it could obtain in a comparable arm's length transaction, (ii) is
contemplated by the Stockholders' Agreement, the Asset Transfer Agreement or the
management advisory agreement among the Company and Vestar and Cabot or (iii) is
for the payment of reasonable and customary regular fees to outside directors.
In no event will the Company issue Aearo Common Stock or other equity securities
to Vestar or Cabot or any affiliate of the Company, subject to certain
limitations, below the fair market value of such shares of Aearo Common Stock or
equity securities.
 
REGISTRATION RIGHTS.  The Stockholders' Agreement provides that, subject to
certain limitations, upon a written request by Vestar or a written request by
Cabot (but only in the event that a period of one year or more has elapsed since
a public offering of Aearo Common Stock without Cabot having an opportunity to
 
                                       57
<PAGE>   60
 
participate), the Company will use its best efforts to effect the registration
of all or part of the Aearo Common Stock owned by such requesting stockholder,
provided that (i) the Company will not be required to effect more than one
registration within any 360 day period and (ii) neither Vestar nor Cabot will be
entitled to request more than two registrations. Under certain circumstances, if
the Company proposes to register shares of Aearo Common Stock, it will, upon the
written request of any stockholder, use all reasonable efforts to effect the
registration of such stockholders' Aearo Common Stock.
 
TERMINATION.  The Stockholders' Agreement will terminate as to any Aearo Common
Stock or Aearo Preferred Stock, subject to certain limitations, on the date such
Aearo Common Stock is sold in a public offering or pursuant to Rule 144. The
rights of Vestar will terminate under the Stockholders' Agreement when Vestar
and its affiliates own no Aearo Common Stock, common stock equivalents or Aearo
Preferred Stock. The rights of Cabot under the Stockholders' Agreement will
terminate on the earliest date when Cabot or its affiliates own no Aearo Common
Stock, common stock equivalents or Aearo Preferred Stock.
 
OTHER RELATIONSHIPS
 
Upon consummation of the Formation Acquisition, the Company paid to Vestar an
investment banking fee of approximately $2.05 million, plus out of pocket
expenses, for Vestar's services in structuring the transaction and providing
financial advice in connection therewith. The Company also paid on Cabot's
behalf to Merrill Lynch & Co. an investment banking fee of approximately $1.1
million, plus out of pocket expenses of Cabot of approximately $250,000 incurred
in connection with the Formation Acquisition.
 
MANAGEMENT ADVISORY AGREEMENT.  In connection with the Formation Acquisition,
the Company became a party to a management advisory agreement with Vestar and
Cabot (the "Management Advisory Agreement"), pursuant to which the Company is
obligated to pay an annual management fee in an aggregate amount with respect to
each fiscal year equal to the greater of (i) $400,000 and (ii) 1.25% of the
consolidated net income of the Company before cash interest, taxes, depreciation
and amortization for such fiscal year to be shared by Cabot and Vestar based on
their relative equity ownership of the Company. Each of Vestar and Cabot
received $200,000 pursuant to the Management Advisory Agreement with respect to
fiscal 1996. Messrs. Alpert, O'Connell and Nagle, three of the directors of the
Company, are affiliated with Vestar in the capacities described under Item 11,
"Management -- Directors and Executive Officers" and, accordingly, benefit from
any payments received by Vestar. Mr. Gilson and Ms. Hanratty, two of the
directors for the Company, are affiliated with Cabot in the capacities described
under Item 11, "Management -- Directors and Executive Officers" and,
accordingly, benefit indirectly from any payments received by Cabot.
 
MANAGEMENT LOANS.  The Company has loaned approximately $934,000 to certain
Management Investors, in order to provide such Management Investors with funds
to be applied to a portion of the purchase price of the Common Stock purchased
by such Management Investors under the Stock Purchase Plan in connection with
the Formation Acquisition. Such loans (i) are secured by the Aearo Common Stock
purchased with the proceeds thereof, (ii) have a term of between 5 and 10 years,
(iii) bear interest at an annual rate of 7%, and (iv) are subject to mandatory
prepayment in the event the employment of such Management Investor terminates.
At September 30, 1996, amounts outstanding under such loans to Messrs. Young,
Carey, O'Connor, Hall, Mallitz, and Tremallo were $157,500, $100,000, $81,000,
$102,828, $93,624 and $60,000, respectively.

(1)   Ratio of earnings to fixed charges is defined as pre-tax income from
      continuing operations plus fixed charges divided by fixed charges. Fixed
      charges include interest (including amortization of debt issuance costs)
      and a portion of rental expense assumed to represent interest. Earnings
      for the period ended September 30, 1995 would have been insufficient to
      cover fixed charges by $0.2 million.
