respectively.


                                       2
<PAGE>   4


The Safety Prescription Eyewear ("SRx") segment manufactures and sells products
that 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 end-user's prescription, and then assembles the glasses using the
end-user's choice of frame. The Safety Prescription Eyewear segment accounted
for approximately 13% of the Company's net sales in fiscal 2000 and
approximately 12% in both fiscal 1999 and 1998.

The Specialty Composites segment manufactures a wide array of energy-absorbing
materials that are incorporated into other manufacturers' products to control
noise, vibration and shock. Specific product applications for such materials
include noise-reducing and vibration-damping matting used in under hood and cab
treatments of transportation equipment such as Class 8 heavy trucks, shock
protection parts for electronic devices such as computer disk drives, servers,
and durable energy-absorbent and cushioning foams used in footwear. Specialty
Composites also produces specially formulated foam used in the manufacture of
the Safety Products segment's polyvinylchloride ("PVC") earplugs. Specialty
Composites accounted for approximately 15% of the Company's net sales in fiscal
2000 and fiscal 1999, and approximately 14% in fiscal 1998.

     PRODUCTS - SAFETY PRODUCTS SEGMENT

Within Safety Products, the Company classifies its products in five main
categories: hearing protection and communication headsets; eyewear; face and
head protection; respiratory protection; and other protection products.

HEARING PROTECTION. The Company's hearing protection products primarily consist
of disposable earplugs, reusable earplugs, and earmuffs. The Company has been a
leader in hearing conservation research and development since 1972, when it
first introduced the PVC disposable earplug. Today, this product is known as the
"Classic" (R) and its color yellow is a registered trademark of the Company in
the United States and Canada. This product, and the recently introduced and
patented Super-Fit(TM) product, is designed to be "rolled down" or compressed
before being inserted into the ear, and, as a result of its unique slow recovery
characteristics, the plug slowly expands (or "recovers") to fill the ear canal
and provide the desired protection. The Company's PVC earplugs are available
corded and uncorded and in a variety of packaging options. The Company also
produces versions of the PVC plug for many of the international airlines for
inclusion in their amenity kits. In addition the Company manufactures a full
line of polyurethane earplugs, including its E-Z-Fit(R), TaperFit(R),
E-A-Rsoft(TM), and Yellow Neons(TM) products. These products serve the same
disposable earplug category, but the PVC earplugs have historically led the
market.

In the reusable earplug segment of the market, the Company offers its patented
UltraFit(R) product, and the E-A-R(R) Express(R) a patented product, which
features a polyurethane pod and a short plastic stem to facilitate sanitary and
easy insertion of the plug into the ear. The Company also offers the "Flex"(TM)
line of "semi-aural" banded products, designed for intermittent use. These
products feature articulating arms which allows for use in multiple positions
and for easy storage around the neck.

The Company sells a full range of earmuffs. Under its Peltor brand, the Company
manufactures, assembles and sells a broad line of earmuffs and communication
headsets. The Company is a leader in providing noise attenuating headsets and
wireless and hardwire communication headsets. These products serve 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 environments exist,
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.

EYE PROTECTION. Non-prescription eye and face protection is used in work
environments where a number of hazards present a danger to the eyes and face,
including dust, flying particles, metal fragments, chemicals, extreme glare and
optical radiation. The Company offers a large number of task-specific
non-prescription safety eyewear products. The basic categories of
non-prescription eyewear protection are non-prescription safety (or "plano")
eyewear and goggles:

     -    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 applications. As part of the continuing
          product development efforts the Company now markets its unique Lexa(R)
          safety eyewear products which feature a patented contoured lens which
          wraps around the wearer's face, improving peripheral vision, and
          eliminating the need for separate side shields.


                                       3
<PAGE>   5


     -    Goggles. The Company manufactures and sells a broad line of goggles,
          which are typically required 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 operations. To meet these requirements, the Company
          manufactures a variety of vented and non-vented goggles with varying
          fields of view.

FACE AND HEAD PROTECTION. Face and head protection is used in work environments
where a number of hazards present a danger to the eyes, face and head, including
dust, flying particles, metal fragments, chemicals, extreme glare, optical
radiation and items dropped from above. The basic categories of face and head
protection are faceshields and hard hats:

     -    Faceshields. Faceshields are designed to protect against heat, splash
          and flying particles and are worn in conjunction with other protective
          equipment, such as plano eyewear and respirators. The patented AO
          TuffMaster(R) line of faceshields is one of the leading brands in the
          market.

     -    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, and a wide
          selection of colors and custom imprinting.

RESPIRATORY PROTECTION. Respiratory protection products are used to protect
against the harmful effects of contamination and pollution caused by dust,
gases, fumes, sprays and other contaminants. The Company offers a broad line of
disposable dust and mist masks, cartridge-equipped quarter-, half- and full-face
respirators, and "escape" respirators (a single-use respirator for emergencies).

OTHER PROTECTION PRODUCTS. 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 while also increasing the Company's presence in the
Consumer/Do-It-Yourself(DIY) market. First aid kits are either for general use
or for industrial or commercial uses. Additional products in this group include
safety vests.

     PRODUCTS - SAFETY PRESCRIPTION EYEWEAR SEGMENT

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 end
user's prescription, and then assembles the glasses using the end user'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 care
professionals as an essential part of its SRx business.

     PRODUCTS - SPECIALTY COMPOSITES SEGMENT

The Company's Specialty Composites segment manufactures a wide array of
impact-resistant, shock and energy-absorbing materials for a variety of
applications employing 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 earplugs. The
principal strengths of Specialty Composites are its specialized polyurethane
formulations, its thin-sheet casting capability, its composite technologies and
its applications and materials engineering. These strengths allow the Company to
manufacture in a single process, high value-added composites using casting,
extrusion and molding processes.

Specialty Composites' products fall into three broad categories: barriers and
absorbers for airborne 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(R) LS polyurethane high
density cellular foams, which are manufactured by three production lines in a
variety of thicknesses, widths, colors and densities for reduction of excessive
vibration, noise and shock control and high resilience cushioning and sealing
applications; the Confor(R) 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(R) PVC
foams for mechanical vibration reduction and noise and shock control.

SALES AND MARKETING

The Company divides its sales force into its three business segments, as
follows:

     SALES AND MARKETING - SAFETY PRODUCTS SEGMENT

Within Safety Products, sales are managed through four channels: North American
Industrial Distribution; Consumer/Do-It-Yourself ("DIY"); Europe; and
International. Each of these channels has its own sales force and its own
distinct yet synergistic sales strategies. In addition, through the acquisitions
of Peltor and Norhammer, the Company has significantly expanded its sales
coverage, including a dedicated effort to serve the specialty communications
earmuff market.

     -    North American Industrial Distribution. This is the largest sales
          channel for Safety Products and includes approximately 200 Dialog(TM)
          industrial distributors and approximately 160 industrial dealers in
          the U.S., Canada and Mexico. Participation in the Dialog(TM) program
          requires minimum purchase levels while encouraging support across the
          full product line, in return for rebates based on growth and volume as
          well as preferred treatment regarding shipping terms, new products,
          field sales support, and cooperative advertising. The Company also
          offers Dialog(TM) distributors financial incentives for establishing
          electronic order entry/invoicing interfaces with the Company and for
          developing marketing programs which promote the Company's products.

     -    Consumer. Under the AOSafety(R) brand name, the Company is America's
          leading supplier of personal safety products. The AOSafety(R) brand
          offers a wide variety of quality products to meet existing and
          emerging consumer personal safety needs in many marketplaces. Within
          the Hardware/Do-it-Yourself marketplace, AOSafety(R) is the primary
          brand carried by The Home Depot, Ace, TruServ, Lowe's and other
          retailers. AOSafety(R) also has a position in the "shooting/hunting"
          safety product marketplace. Further AOSafety(R) products are marketed
          in drugstore channels.

     -    Europe. The Company has a significant presence in Europe with sales
          offices in the U.K., Sweden, Germany, France, Italy and Spain. 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 Brand Manager to lead and train the
          existing sales organization and its Distributor base.

     -    International. The Company exports its products around the world, and
          this channel is managed through sales representatives located in
          Singapore, Miami (covering the Caribbean and Central America), Brazil,
          Australia, New Zealand and South Africa (covering the Middle East).

     SALES AND MARKETING - SAFETY PRESCRIPTION EYEWEAR SEGMENT (SRX)

The SRx segment employs its own sales force to sell its products throughout
North America. Approximately 90% of the Company's safety prescription eyewear is
sold directly to more than 15,000 industrial locations, 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 and direct to eye
care professionals.

     SALES AND MARKETING - SPECIALTY COMPOSITES SEGMENT

The Company relies upon an organization of direct sales representatives and
independent agents to identify OEM applications for Specialty Composites'
products and technologies. Once such applications have been identified, the
Company's sales and technical staffs 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. Currently, Specialty Composites'
products are sold into three markets: transportation; health-related; and
original equipment manufacturers ("OEM") in industrial applications such as
electronics and industrial equipment.

     TRANSPORTATION MARKET. Specialty Composites' products are incorporated into
     heavy trucks, automobiles, yachts, aircraft, buses, leisure vehicles and
     defense, farm and construction equipment in order to control noise and
     vibration. For example, the Company supplies durable acoustical foams and
     barriers that control sound and help meet noise standards for Class 8 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 damping composites efficiently control sound
     and vibration.

     HEALTH-RELATED MARKET. 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 orthopedic mattresses and pillows, leg


                                       5
<PAGE>   7


     braces, orthotic devices, surgical pillows, wheelchair cushions, bicycle
     helmets, keyboard wrist supports and occupational seating.

     OEM MARKET. 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.

RESEARCH AND DEVELOPMENT

     RESEARCH AND DEVELOPMENT - SAFETY PRODUCTS SEGMENT.

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(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 and programs to encourage hearing conservation. In
order to test the efficacy of its hearing protection products, the Company owns
and operates a National Voluntary Laboratory Accreditation Program ("NVLAP")
laboratory in the United States which is accredited for testing the efficacy of
hearing protection products. The Company also operates sound chambers and
testing facilities that 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 Company also has facilities for
the design and testing of respiratory safety equipment. The research and
development personnel of the Company include recognized experts in the safety
products industry.

     RESEARCH AND DEVELOPMENT - SAFETY PRESCRIPTION EYEWEAR SEGMENT

This segment shares some of the expertise within the Safety Products Segment and
works extensively with outside suppliers for development of frames, lenses and
coatings.

     RESEARCH AND DEVELOPMENT - SPECIALTY COMPOSITES SEGMENT

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 VersaDamp(TM) 2000 thermoplastic elastomers and the Confor(R) heavily damped
viscoelastic foams are being introduced in a growing number of applications
across all markets served by Specialty Composites.

RAW MATERIALS AND SUPPLIERS

The Company buys and consumes a wide variety of raw materials, component parts,
office supplies, and maintenance and repair parts. Significant categories
purchased include corrugated paper products, poly packaging films, chemicals,
eyewear frames and optical lenses. The chemical category includes plastic resins
such as polycarbonates, propionates, polyols, plasticizers, substrates,
pre-polymers, isocyanates and adhesives. The eyewear frames are for both the
nonprescription and SRx products.

The Company does have a diverse base of material suppliers and is subject to
market risks with respect to industry pricing in paper and crude oil as it
relates to various commodity items. Items of potential impact include
paperboard, packaging films, nylons, resins, propylene, ethylene, plasticizer
and freight. With reference to supplier agreements that allow for price changes
based upon an index the Company builds anticipated commodity price movements
into each year's planning cycle. The Company manages pricing pressure exposure
on large volume commodities such as polycarbonate, polyols and polyvinyl
chloride via price negotiations utilizing alternative supplier competitive
pricing. However, where appropriate, the Company will use a single source for
supply of certain items. In addition, based on the material, availability of
supply, level of quality and the technical difficulty to produce, the Company
will use a major and minor source to insure continued best pricing and a ready
back up supply. The Company does not enter into derivative instruments to manage
commodity risk.

With the exception of polycarbonate, 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. Due to two global polycarbonate manufacturers
experiencing significant manufacturing problems this supply of material has
created a very global tight supply. The Company's supplier has not had
manufacturing supply problems, therefore availability has not been an issue. Due
to tight supply, the Company did experience price increases in fiscal year


                                       6
<PAGE>   8


2000. No subsequent increases are expected in fiscal year 2001. As a contingency
to potential spot supply outages, inventory has been increased to levels that
the Company believes would be sufficient to support the businesses through an
outage. In addition, the Company is continuing to qualify other sources of
supply.

Although the Company outsources the production of less than 10% of its products
to various manufacturers, the Company has found resource availability, abundant
supplier competition and infrastructure stability in the Far East to provide
favorable supply opportunities.

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 earplugs); high speed assembly and packaging of earplugs; plastic injection
molding, coating and assembly of non-prescription eyewear; and assembly,
grinding, polishing and coating of prescription eyewear. The Company also
utilizes a number of contract manufacturers in the United States, Mexico, and
Europe to supplement internal operations and to assemble and/or manufacture
products where the Company does not have world class processing capabilities.
The Company will continue to use contract manufacturers where appropriate to
remain competitive and maximize profit margins. Consistent across all of the
Company's manufacturing operations is an emphasis on producing high quality
products. Currently, all 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 is currently working toward QS 9000 certification for
the Specialty Composites operations. 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.

     MANUFACTURING AND DISTRIBUTION OPERATIONS - SAFETY PRODUCTS SEGMENT

The Company's Indianapolis, Indiana plant is the largest earplug manufacturing
facility in the world. It fabricates, molds and packages hundreds of millions of
pairs of earplugs 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 earplugs facilitate cost-savings, high-volume production and
improved cycle times and inventory management. The Southbridge, Massachusetts
facility is the Company's largest manufacturing site and manufactures a wide
variety of Personal Protection Equipment. These manufactured safety products
include respiratory, plug and muff type hearing, head and face, and a broad
offering of safety eyewear protection. All Company manufacturing sites have
implemented a number of initiatives resulting in significant improvements in the
areas of safety, quality, cost, and customer service.

The Company's principal international manufacturing operations are located in
Poynton, England; Varnamo, Sweden; and Ettlingen, Germany. The Poynton facility
serves customers in Western Europe, producing and packaging earplugs and other
hearing and eyewear products. The Varnamo, Sweden plant is the principal Peltor
manufacturing location supplying finished goods and components to customers and
other subsidiaries from this location. Certain of these products are received in
the Ettlingen, Germany plant that provides an assembly operation for the
components and a stocking facility for finished goods for shipment to customers.

The Company fills virtually all of its domestic and certain of its international
orders 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.

     MANUFACTURING AND DISTRIBUTION OPERATIONS - SAFETY PRESCRIPTION EYEWEAR
     SEGMENT

The SRx production operations are comprised of three facilities located in the
U.S., two in Canada and one in Europe. The U.S. locations include the Athens,
Tennessee lab acquired in 1999 as well as locations in Indiana and Oklahoma. In
Canada, the Mississauga, Ontario plant fabricates prescription eyewear and,
together with a small prescription eyewear laboratory in Montreal, produces SRx
products for the Canadian market. In Poynton, England, the Company has a small
SRx laboratory that serves primarily the U.K. market. These facilities possess
lens surfacing edging, grinding and coating machinery


                                       7
<PAGE>   9


capable of handling glass, plastic and polycarbonate lenses. The lenses are then
fitted into frames and the finished product is shipped to customers. These
facilities currently manufacture and distribute approximately 500,000 pairs of
safety prescription glasses annually.

     MANUFACTURING AND DISTRIBUTION OPERATIONS - SPECIALTY COMPOSITES SEGMENT

Specialty Composites' products are manufactured in Indianapolis, Indiana and
Newark, Delaware. The Indianapolis plant, which supplies specially formulated
foam for the Company's PVC earplugs, 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
manufactures polyurethane foams and films and houses the Company's proprietary,
thinsheet foam casting line, which permits the casting of both sheet and
composite materials, including facings and substrates, in a single pass through
the line.

COMPETITION AND THE PERSONAL PROTECTION EQUIPMENT MARKET

A 1998 industry study prepared by Frost & Sullivan estimates that 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 $1.3 billion in 1997.
Management estimates annual sales outside the United States for the segment of
the PPE market in which the Company competes were in excess of $1.2 billion in
1997.

The PPE market is fragmented and highly competitive as a large number of
relatively small, independent manufacturers with limited product lines serve the
PPE market. The Company estimates that there are more than 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, 2000, the Company had 1,657 employees, of whom 1,094 were
primarily engaged in manufacturing, 380 in sales, marketing and distribution, 55
in research and development and 130 in general and administrative. The Company
believes its employee relations are good. The Company has one domestic U.S.
facility that employs union members. This facility, located in Plymouth,
Indiana, employs 37 members of the International Union of Electronic,
Electrical, Salaried, Maritime and Furniture Workers (out of a total of 79
employees), and the Company's relations with these union members are fully
satisfactory. The union contract expires on June 26, 2001.

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 earplugs 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 in the
future not exceeding 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 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 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(R)
Division from American Optical Corporation in April 1990. The Company is
contingently liable with respect to numerous lawsuits involving respirators sold
by American Optical Corporation prior to the acquisition of the AOSafety(R)
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.

As part of a trademark dispute with Moldex-Metric, Inc. involving the Company's
"Yellow Neon Blasts"(TM) polyurethane earplugs, a federal district court in
Southern California issued a preliminary injunction in October, 2000 which
required the Company to immediately withdraw the current version of "Yellow Neon
Blasts"(TM) polyurethane earplugs from the U.S. market, and to also advise its
distributors to withdraw this product from the market, until the trademark issue
could be resolved. In accordance with this ruling, the Company ceased the
manufacturing and distribution of "Yellow Neon Blasts"(TM). The Company appealed
the preliminary injunction and the court granted a stay of the injunction
pending appeal to the Ninth Circuit. "Yellow Neon Blasts"(TM) was introduced
approximately one year ago as part of the Company's new line of polyurethane
earplugs called E-A-Rsoft(TM). Over the past twelve months, "Yellow Neon
Blasts"(TM) has accounted for approximately $1 million of the Company's U.S.
sales (the trademark dispute and the preliminary injunction do NOT include the
E-A-Rsoft(TM) "Yellow Neons"(TM) solidly colored earplugs or any other Company
products). In December, 2000 the Company reached a non-cash settlement with
Moldex-Metric, Inc. whereby the "Yellow Neon Blasts"(TM) would be taken off the
market in the U.S. and Canada. In the opinion of management, this will not have
a material impact on operations.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

On August 10, 2000, the Company held a special meeting of stockholders. The
stockholders approved the selection of Arthur Andersen LLP as the Company's
independent public accountants with a total of 101,987.5 votes in favor, no
votes in opposition and 100 abstention votes. The stockholders voted to elect
the following directors for the ensuing year with a total of 101,987.5 votes in
favor of each director and 100 abstention votes for each director: Norman W.
Alpert, Bryan P. Marsal, John D. Curtin, Jr., Margaret J. Hanratty, William E.
Kassling, Michael A. McLain, Arthur J. Nagle, Daniel S. O'Connell and Robert

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

As of December 1, 2000 there were outstanding 102,087.5 shares of common stock,
par value $0.01 per share, of Aearo ("Aearo Common Stock"). All of the Aearo
Common Stock is held, collectively, by Vestar Equity Partners, L.P. (together
with certain related persons, "Vestar"), Cabot Corporation ("Cabot") and
management. As of December 1, 2000 there were 36 shareholders of record of Aearo
Common Stock. 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 "Senior
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
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.

The Company has never paid cash dividends on the Aearo Common Stock. Payment of
dividends on the Aearo Common Stock is limited by the terms of the Company's
Senior Bank Facilities and Senior Subordinated Notes and is subordinated to
payment of dividends on the Aearo Preferred Stock. See Note 7 to the
Consolidated Financial Statements.

ITEM 6. SELECTED FINANCIAL DATA

The selected historical financial data as of and for the periods ended September
30, 1996, 1997, 1998, 1999, and 2000 are derived from the consolidated financial
statements of Aearo Corporation and subsidiaries. The data should be read in
conjunction with the consolidated financial statements and related notes,

NOTES TO SELECTED FINANCIAL DATA:

(1)  Includes $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.

(2)  Includes $0.8 million charged to selling and administrative expense for
     costs related to the abandoned effort at an initial public offering.

(3)  EBITDA is defined as earnings before interest, taxes, depreciation,
     amortization, and non-operating income or expense. Non-operating income or
     expense is further defined as extraordinary gains or losses, or gains or
     losses from sales of assets other than in the ordinary course of business.
     While the Company believes EBITDA is a useful indicator of its ability to
     service debt, EBITDA should not be considered as a substitute for net
     income determined in accordance with generally accepted accounting
     principles as an indicator of operating performance or as an alternative to
     cash flow as a measure of liquidity. Investors should be aware that EBITDA
     as presented above may not be comparable to similarly titled measures
     presented by other companies and comparisons could be misleading unless all
     companies and analysts calculate this measure in the same fashion. EBITDA
     presented for fiscal 1998 is excluding restructuring charges of $11.6
     million recorded during fiscal 1998.

(4)  Ratio of earnings to fixed charges is defined as pretax income from
     continuing operations plus fixed charges divided by fixed charges. Fixed
     charges include interest expense (including amortization of debt issuance
     costs). Earnings for the period ended September 30, 1997 and 1998 were
     inadequate to cover fixed charges by $6.0 million, and $9.2 million,
     respectively.

(5)  During fiscal 1998 the Company took a restructuring charge of $11.6 million
     related to the restructuring plans announced by the Company during the
     fiscal year. On February 3, 1998, the Company announced the appointment of
     Michael A. McLain as President and Chief Executive Officer and on March 25,
     1998 the Company announced plans to close the Boston headquarters and
     relocate it to Indianapolis, Indiana, where the Company has substantial
     operations. In addition, on September 30, 1998 the Company announced plans
     to improve profitability through complexity reduction and restructuring
     (See Note 16 of Notes to Consolidated Financial Statements).

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 consolidated 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

In the latter part of fiscal 1996, the Company undertook efforts to implement a
new management information system, integrate the Peltor and Eastern acquisitions
that were acquired earlier in that year, and change the manufacturing
orientation at its Southbridge, Massachusetts facility towards cellular
manufacturing. Difficulties associated with the systems conversion as well as
the other initiatives resulted in problems with production planning and control,
shipping and distribution, and overall customer service. Throughout most of
fiscal 1997 the Company spent significant sums in order to mitigate the effects
of these problems on its customer base. As the year progressed, the Company
realized improvements in service levels as well as a return towards historic
levels of profitability.

During fiscal year 1998 the Company continued to realize these improvements and
experienced four successive quarters of operating profitability improvements,
excluding the $11.6 million restructuring charge and $0.5 million of personnel
relocation costs associated with the move of the corporate headquarters from
Boston, Massachusetts to Indianapolis, Indiana, as compared with the same
quarters of the prior year. A new management team was installed, starting with
the appointment of Michael A. McLain as President and Chief Executive Officer on
February 3, 1998. Greater utilization of the new management information system
allowed the Company to realize additional operating improvements. To further
accelerate the operational benefits of the new management information system,
the Company completed a major update of its SAP management information system to
version 3.1H in November 1998 and intends to continue to apply information
system version upgrades as the Company deems appropriate.

During fiscal year 1999 the Company implemented the restructuring plan announced
on September 30, 1998.

1.   The Company reorganized into strategic business segments. The reportable
     segments are Safety Products, Safety Prescription Eyewear and Specialty
     Composites. This change was made to allow greater management attention and
     focus.
2.   The Company rationalized its product line in Safety Products, discontinuing
     over 50% of low volume, low margin stock keeping units. It consolidated its
     product offering to retail customers like Home Depot, Lowe's, ACE, etc.
     under the AOSafety(R) brand name and introduced improved packaging and new
     graphics at the same time. This rationalization has contributed to
     manufacturing efficiencies.
3.   In the Safety Prescription Eyewear segment the Company consolidated its
     customer service and distribution operations.

In addition, there have been continued productivity improvements in purchasing,
logistics and manufacturing. These, along with the restructuring efforts, have
resulted in significant improvements in gross margin versus the previous year.

A part of the savings was re-invested in selling and marketing to build brand
equity and introduce new and innovative products. These included E-A-Rsoft(TM),
Yellow Neons(TM), the recently introduced Super-Fit(TM), Nassau Rave(TM) safety
eyewear, new safety prescription eyewear frames and several new Peltor(R)
communication products. The Lexa(R) product line, first introduced in 1998, has
shown very positive growth.

</TABLE>


(1)  Effective October 1, 1998 the Company reorganized its financial reporting
     into the three reportable segments of Safety Products, Safety Prescription
     Eyewear and Specialty Composites.

FISCAL 2000 COMPARED TO FISCAL 1999

NET SALES. Net sales in the year ended September 30, 2000 increased 5.0% to
$305.0 million from $290.4 million in the year ended September 30, 1999 as the
sales in all three reportable segments increased. The Safety Products segment
net sales in the year ended September 30, 2000 increased $7.2 million to $219.3
million from $212.1 million, or 3.4% even though the effect of the stronger U.S.
dollar as compared to the European and Canadian currencies, was to depress sales
by approximately $6.4 million. Sales in Europe, to North American Consumer
customers and to international customers were all higher than in the prior year.
The Safety Prescription Eyewear segment net sales in the year ended September
30, 2000 increased 12.4% to $39.9 million from $35.5 million in the year ended
September 30, 1999. The Safety Prescription Eyewear segment net sales for the
year ended September 30, 2000 included approximately $4.0 million of sales from
Safety Optical that was acquired in August 1999. The Specialty Composites
segment net sales in the year ended September 30, 2000 increased $3.0 million to
$45.8 million from $42.8 million, or 7.0%. Increased sales were due to continued
growth in sales of engineered products to the general aviation and precision
equipment markets while sales into the trucking segment were lower by
approximately 2%.

GROSS PROFIT. Gross profit in the year ended September 30, 2000 increased 7.9%
to $143.4 million from $132.9 million in the year ended September 30, 1999.
Gross profit as a percentage of net sales in the year ended September 30, 2000
was 47.0% as compared to 45.8% in the year ended September 30, 1999. The
continued productivity improvements in purchasing and manufacturing, especially
in the manufacturing of the non-prescription eyewear product lines were the
primary factors behind a strong improvement in the gross profit performance. The
gross profit would have been approximately 47.6% had it not been for the
weakness of the euro that depresses revenue while having a more limited impact
on manufacturing costs.

SELLING AND ADMINISTRATIVE EXPENSES. Selling and administrative expenses in the
year ended September 30, 2000 increased 9.7% to $94.3 million from $86.0 million
in the year ended September 30, 1999. Selling and marketing spending increased
$2.9 million as part of the Company's campaign to build brand awareness and
loyalty by more strongly promoting its global brands. Administrative costs were
higher due to higher legal costs driven by the Moldex-Metric, Inc. trademark
dispute which was settled December 6, 2000, and the development of an E-Commerce
initiative designed to enhance the electronic


                                       16
<PAGE>   18


commerce capability between the Company and its customers. Selling and
administrative expenses as a percentage of net sales in the year ended September
30, 2000 were 30.9% of net sales, compared to 29.6% in the year ended September
30, 1999.

RESEARCH AND TECHNICAL SERVICES EXPENSES. Research and technical services
expenses in the year ended September 30, 2000 increased 17.0% to $5.5 million
from $4.7 million in the year ended September 30, 1999. This increase was due to
additional focus in the design and development of new products and technologies.

AMORTIZATION OF INTANGIBLES. Amortization expense remained at a relatively
consistent $6.9 million in the year ended September 30, 2000 compared to $6.8
million in the year ended September 30, 1999.

OTHER (INCOME) CHARGES, NET. Other Charges (Income), Net was income of $0.3
million for the year ended September 30, 2000 as compared to expense of $0.8
million for the year ended September 30, 1999. The $0.3 million income for the
year ended September 30, 2000 was primarily attributed to foreign currency
transaction gains of approximately $0.9 million somewhat offset by the $0.5
million write off of an abandoned information technology system that was under
development for the Safety Prescription Eyewear segment. The $0.8 million
expense for the year ended September 30, 1999 was primarily attributed to
foreign currency transaction losses of approximately $0.6 million.

OPERATING INCOME. Primarily as a result of the factors discussed above,
operating income increased $2.4 million to $37.0 million, or 6.9%, in the year
ended September 30, 2000 from $34.6 million in the year ended September 30,
1999. Operating income as a percentage of net sales in the year ended September
30, 2000 was 12.1% as compared to 11.9% in the year ended September 30, 1999.

INTEREST EXPENSE, NET. Interest expense, net in the year ended September 30,
2000 remained relatively constant at $24.4 million compared to $24.3 million for
the year ended September 30, 1999. The increase is attributed to an increase in
the weighted average interest rates in effect for the year, mostly offset by
lower average borrowings.

INCOME (LOSS) BEFORE PROVISION FOR INCOME TAXES. Income before provision for
income taxes increased $2.3 million in the year ended September 30, 2000 to
income of $12.6 million compared to income of $10.3 million in the year ended
September 30, 1999 due to the improved operating income.

PROVISION FOR INCOME TAXES. The provision for income taxes in the year ended
September 30, 2000 was $3.6 million compared to $3.2 million in the year ended
September 30, 1999.

NET INCOME (LOSS). For the year ended September 30, 2000, the Company had net
income of $9.0 million as compared to $7.1 million for the year ended September
30, 1999.

EBITDA. EBITDA is defined as earnings before interest, taxes, depreciation,
amortization, and non-operating income or expense. Non-operating income or
expense is further defined by the Company as extraordinary gains or losses, or
gains or losses from disposition of assets other than in the ordinary course of
business. While the Company believes EBITDA is a useful indicator of its ability
to service debt, EBITDA should not be considered as a substitute for net income
determined in accordance with generally accepted accounting principles as an
indicator of operating performance or as an alternative to cash flow as a
measure of liquidity. Investors should be aware that EBITDA as presented below
may not be comparable to similarly titled measures presented by other companies
and comparisons could be misleading unless all companies and analysts calculate
this measure in the same fashion.

                                         =========================================================
</TABLE>


EBITDA for the year ended September 30, 2000 was $54.6 million, which was $3.6
million higher than for the year ended September 30, 1999. This increase was due
primarily to improved sales volume, a strong gross margin performance partially
offset by increased spending in selling, general administrative, and technical
costs. EBITDA as a percentage of net sales in the year ended September 30, 2000
was 17.9% as compared to 17.6% in the year ended September 30, 1999.

FISCAL 1999 COMPARED TO FISCAL 1998

NET SALES. Net sales in the year ended September 30, 1999 decreased 0.7% to
$290.4 million from $292.5 million in the year ended September 30, 1998. The
Safety Products segment net sales in the year ended September 30, 1999 decreased
$4.4 million to $212.1 million from $216.5 million, or 2.0%. Higher sales in
Europe and to Consumer customers in North America were offset by the effects of
product rationalization, increased competitive activity in the eyewear product
line earlier in the year, the effects of a stronger US dollar, and decline in
business with customers in Asia. The effect of the stronger U.S. dollar as
compared to the European and Canadian currencies, was to decrease sales by
approximately $1.3 million. The Safety Prescription Eyewear segment net sales in
the year ended September 30, 1999 decreased 2.4% to $35.5 million from $36.4
million in the year ended September 30, 1998. The Safety Prescription Eyewear
segment net sales for the year ended September 30, 1999 included $0.7 million of
sales from Safety Optical that was acquired in August 1999. The Specialty
Composites segment net sales in the year ended September 30, 1999 increased $3.2
million to $42.8 million from $39.6 million, or 8.2%. Increased sales were due
to continued growth in sales of engineered products to the general aviation and
precision equipment markets.

GROSS PROFIT. Gross profit in the year ended September 30, 1999 increased 3.3%
to $132.9 million from $128.6 million in the year ended September 30, 1998.
Gross profit as a percentage of net sales in the year ended September 30, 1999
was 45.8% as compared to 44.0% in the year ended September 30, 1998. The
continued productivity improvements in purchasing and manufacturing, especially
in the manufacturing of the eyewear product line were the primary factors behind
a strong improvement in gross profit performance as compared to the previous
year. Product rationalization as a result of the restructuring plan announced
during fiscal year 1998 also contributed to efficiencies in operations due to
reduced complexity.

SELLING AND ADMINISTRATIVE EXPENSES. Selling and administrative expenses in the
year ended September 30, 1999 decreased 3.3% to $86.0 million from $88.9 million
in the year ended September 30, 1998. Within this decrease is an increase of
$5.0 million in selling and marketing expenses as part of the Company's campaign
to build brand awareness and loyalty by more strongly promoting its global
brands. Customer service and distribution expenses decreased as the Company
realized headcount and overhead reductions in the Safety Prescription Eyewear
segment through consolidations of these activities, and achieved productivity
improvements within the Safety Products segment's international distribution
facility in Indianapolis, Indiana. Administrative costs were lower due to
decreased headcount as a result of the restructuring plan announced during
fiscal year 1998. In addition, fiscal year 1998 expenses were higher due to the
costs related to a patent infringement claim by Gargoyles, Inc., which was
settled October 22, 1998, as well as $0.5 million of personnel relocation costs
associated with the move of the corporate headquarters from Boston,
Massachusetts to Indianapolis, Indiana. Selling

and administrative expenses as a percentage of net sales in the year ended
September 30, 1999 were 29.7% of net sales, compared to 30.4% in the year ended
September 30, 1998.

OTHER (INCOME), CHARGES NET. Other Charges (Income), Net was an expense of $0.8
million for the year ended September 30, 1999 as compared to income of $0.3
million for the year ended September 30, 1998. This change was primarily a
result of foreign currency transaction losses in the year ended September 30,
1999, as compared to foreign currency transaction gains in the year ended
September 30, 1998.

RESTRUCTURING CHARGE. During fiscal 1998 the Company recorded a restructuring
charge of $11.6 million related to the restructuring plans announced by the
Company during that fiscal year. The restructuring included changes in senior
management personnel, relocation of the Company headquarters from Boston to
Indianapolis, and initiatives to improve profitability through complexity
reduction and product line focus. The Company eliminated certain product
offerings in its Eyewear and Respiratory product lines, reduced head count in
its North American operations, and consolidated the branding in its Consumer
product line. For the years ended September 30, 1999 and September 30, 2000, no
restructuring charges were recorded.

OPERATING INCOME. Primarily as a result of the factors discussed above,
operating income excluding the restructuring charge, increased $6.1 million or
21.5% in the year ended September 30, 1999 from $16.9 million in the year ended
September 30, 1998. Operating income as a percentage of net sales in the year
ended September 30, 1999 was 11.9% as compared to 5.8% in the year ended
September 30, 1998.

INTEREST EXPENSE, NET. Interest expense, net in the year ended September 30,
1999 decreased 7.0% to $24.3 million from $26.2 million in the year ended
September 30, 1998. The decrease is attributed to lower average borrowings and a
lower weighted average interest rate in the year ended September 30, 1999 as
compared to the year ended September 30, 1998.

INCOME (LOSS) BEFORE PROVISION FOR INCOME TAXES. Income before provision for
income taxes, excluding the restructuring charge, increased $8.0 million in the
year ended September 30, 1999 to income of $10.3 million compared to income of
$2.3 million in the year ended September 30, 1998 due to the improved operating
income and lower interest expense.

PROVISION FOR INCOME TAXES. The provision for income taxes in the year ended
September 30, 1999 was $3.2 million compared to $2.2 million in the year ended
September 30, 1998.

NET INCOME (LOSS). For the year ended September 30, 1999, the Company had net
income of $7.1 million as compared to a net loss of $11.4 million for the year
ended September 30, 1998.

EBITDA. EBITDA is defined as earnings before interest, taxes, depreciation,
amortization, and non-operating income or expense. Non-operating income or
expense is further defined by the Company as extraordinary gains or losses, or
gains or losses from disposition of assets other than in the ordinary course of
business. While the Company believes EBITDA is a useful indicator of its ability
to service debt, EBITDA should not be considered as a substitute for net income
determined in accordance with generally accepted accounting principles as an
indicator of operating performance or as an alternative to cash flow as a
measure of liquidity. Investors should be aware that EBITDA as presented below
may not be comparable to similarly titled measures presented by other companies
and comparisons could be misleading unless all companies and analysts calculate
this measure in the same fashion.

(1)  Excluding restructuring charge of $11.6 million recorded during fiscal year
     1998.

EBITDA for the year ended September 30, 1999 was $51.0 million, which was $3.9
million higher than September 30, 1998. This increase was due primarily to the
strong gross margin performance combined with reduced selling, general and
administrative costs. EBITDA as a percentage of net sales in the year ended
September 30, 1999 was 17.6% as compared to 16.1% in the year ended September
30, 1998, excluding the 1998 restructuring charge.

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 Canada in local currency. While many of the Company's selling and
distribution costs are also denominated in these currencies, a large portion of
product costs are U.S. Dollar denominated. As a result, a decline in the value
of the U.S. Dollar relative to other currencies can have a favorable impact 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. As a result of the acquisition of Peltor AB, the
Company's operations are also affected by changes in exchange rates relative to
the Swedish Krona. A decline in the value of the Krona relative to other
currencies can have a favorable impact on the profitability of the Company and
an increase in the value of the Krona relative to other currencies can have a
negative impact on the profitability of the Company.

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.

YEAR 2000 COMPLIANCE

The Company did not experience significant problems related to systems
recognizing date sensitive information as a result of the year 2000. The costs
associated with making its information systems year 2000 compliant were not
material.


                                       20
<PAGE>   22


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 Company's debt structure includes $100.0 million of Senior Subordinated
Notes (Notes) due 2005, as well as a senior bank facility comprised of (i) term
loans denominated in U.S., Canadian, British and German currencies aggregating
$140.0 million at inception (the Term Loans) and (ii) a Revolving Credit
Facility providing for up to $25.0 million (the Senior Bank Facilities) for
general corporate purposes and, as to $15.0 million thereof, to finance
permitted acquisitions.

Maturities under the Company's Term Loans are: $19.1 million in fiscal 2001,
$32.6 million in fiscal 2002, $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 Notes until maturity.
The Company will also be required to make interest payments with respect to both
the Senior Bank Facilities and the Notes.

The Company typically makes capital expenditures related primarily to the
maintenance and improvement of manufacturing facilities. The Company spent $9.6
million for capital expenditures for the year ended September 30, 2000 as
compared to $8.4 million for capital expenditures for the year ended September
30, 1999 and $5.8 million for the year ended September 30, 1998. The Company's
capital spending is of a relatively short duration, with the complete commitment
process typically involving less than one year.

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, 2000 totaled $27.6 million
as compared to $26.3 million in 1999. The increase was due primarily to a $2.0
million improvement in Net Income and $0.4 million of higher charges for
depreciation and amortization, partially offset by an unfavorable change of $1.5
million in the Company's net change in assets and liabilities. The Company's net
change in assets and liabilities was primarily driven by an increase in the
change in receivables of $4.0 million, a decrease in the change in accounts
payable and accrued liabilities of $2.5 million offset by a $2.1 million
decrease in the net change in inventories, as well as a $2.9 million decrease in
the net change in other assets and liabilities. The $2.9 million decrease in
other assets and liabilities is primarily related to a decrease in
prepaid/deferred charges and an increase in income taxes payable.

Net cash used by investing activities was $14.0 million for the year ended
September 30, 2000 as compared to $12.1 million for the year ended September 30,
1999 and $5.8 million in the year ended September 30, 1998. Net cash used by
investing activities consisted of $9.6 million of capital expenditures in the
year ended September 30, 2000 as compared to $8.4 million in the year ended
September 30, 1999. In addition the Company invested $4.1 million for the
acquisition of Norhammer and $0.3 million for the acquisition of Livax in fiscal
2000 and $3.7 million for the acquisition of Safety Optical in fiscal 1999.

Net cash used by financing activities for the year ended September 30, 2000 was
$11.6 million compared with $16.2 million in 1999 and $13.0 million in 1998. The
increase of $4.6 million in fiscal 2000 consisted of $6.3 million of increased
borrowings under the revolving credit facility, offset by $2.3 million for the
repayment of term loans. In 1998 net cash used for financing activities included
$10.5 million for the repayment of term loans, $0.3 million for the repayment of
other long term debt, and $2.2 million of increased borrowings under the
revolving credit facility.

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 (subject to certain customary drawing conditions) to
meet its liquidity needs. The Company anticipates that operating cash flow will
be adequate to meet its operating 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 may be impacted by service
levels, continued new product development, worldwide economic conditions and
competitive pressures. In particular, the Company was adversely affected by the
strength of the U.S. Dollar relative to the Euro. 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 to finance such
acquisitions.

The Company's ability to borrow is limited by covenants in the Senior Bank
Facilities and the Notes. During 1997 & 1998 the company made modifications to
the credit agreement. On December 14, 2000, the Senior Bank Facilities were
amended with respect to covenant modifications and other matters applicable to
the periods ending on and after December 31, 2000.

ITEM 7A: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risks related to change in foreign currencies,
interest rates and commodity pricing. The Company uses derivatives to mitigate
impact of changes in foreign currencies and interest rates. All derivative
activities are for purposes other than trading.

FOREIGN CURRENCY RISK

The Company's results of operations are subject to risk associated with
operating in foreign countries, including fluctuations in currency exchange
rates. With a large portion of product sold in Europe produced in the United
States and Sweden a decline in the dollar or krona can have a negative impact on
the profitability of the Company (see Effects of Changes in Exchange Rates in
Management's Discussion and Analysis of Financial Condition and Results of
Operations). The Company executes two hedging programs; one for transaction
exposures, and the other for cash flow impact on European operations. The
Company utilizes forward contracts for transaction exposures and a combination
of forward contracts, zero premium collars and put option contracts for cash
flow exposures. During the year ended September 30, 2000 net transaction losses
were $0.5 million, while cash flow hedges were a gain of $1.4 million. In
addition, the Company limits foreign exchange impact on the balance sheet with
foreign denominated debt in Great Britain Pound Sterling (GBP) and German Marks
(DEM). The Company does not consider the notional amount of outstanding hedge
contracts at September 30, 2000 as material. Settlement of outstanding contracts
as of September 30, 2000 will not have a material impact on the profitability of
the Company.

INTEREST RATES

The Company is exposed to market risk changes in interest rates through its
debt. The Company utilizes interest rate swaps to reduce the impact of increased
interest rates in its floating rate debt. With the continuing increases in
interest rates since June of 1999, the Company unwound its zero premium collar
on February 28, 2000, rolling gains into a new interest rate swap that matches
the notional amounts of the credit agreement by loan currency. The new interest
rate swaps will expire August 31, 2001. The Company is of the opinion that it is
well positioned to manage interest expense through August 2001 and has mitigated
the risks of continued interest rate hikes and the related profit impact on the
Company's financial statements through these efforts. During the year ended
September 30, 2000, the Company incurred an additional $0.2 million of interest
expense as a result of the interest rate swaps.

COMMODITY RISK

The Company is subject to market risks with respect to industry pricing in paper
and crude oil as it relates to various commodity items. Items with potential
impact are paperboard, packaging films, nylons, resins, propylene, ethylene,
plasticizer, and freight. The Company manages pricing exposures on larger volume
commodities such as polycarbonate, polyols and polyvinyl chloride via price
negotiations utilizing alternative supplier competitive pricing. The Company
sources some products and parts from the Far East where resource availability,
competition, and infrastructure stability has provided a favorable purchasing
environment. The Company does not enter into derivative instruments to manage
commodity risk.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Board of Directors and Stockholders of
Aearo Corporation:

We have audited the accompanying consolidated balance sheets of Aearo
Corporation and subsidiaries (a Delaware corporation) as of September 30, 1999
and 2000, and the related consolidated statements of operations, stockholders'
equity and cash flows for the years ended September 30, 1998, 1999 and 2000.
These financial statements and the schedule referred to below are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and the schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. 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 audits provide 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 and
subsidiaries as of September 30, 1999 and 2000, and the results of their
operations and their cash flows for the years ended September 30, 1998, 1999 and
2000, in conformity with accounting principles generally accepted in the United
States.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index to the
accompanying financial statements is presented for purposes of complying with
the Securities and Exchange Commission's rules and is not part of the basic
financial statements. The schedule has been subjected to the auditing procedures
applied in our audits of the basic financial statements and, in our opinion,
fairly states, in all material respects, the financial data required to be set
forth therein in relation to the basic financial statements taken as a whole.

                       AEARO CORPORATION AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) BASIS OF PRESENTATION

Aearo Corporation, a Delaware corporation, and its direct wholly owned
subsidiary, Aearo Company, a Delaware corporation (collectively referred to
herein as the Company), manufactures and sells products through three reportable
segments. The Company's segments are Safety Products, Safety Prescription
Eyewear and Specialty Composites. The Safety Products segment manufactures and
sells hearing protection devices, non-prescription safety eyewear, face shields,
reusable and disposable respirators, hard hats and first aid kits under the
brand names: AOSafety(R), E-A-R(R), and Peltor(R). The Safety Prescription
Eyewear segment manufactures and sells prescription eyewear products that are
designed to protect the eyes from the typical hazards encountered in the
industrial work environment. The Company's Safety Prescription Eyewear segment
purchases component parts (lenses and the majority of its frames) from various
suppliers, grinds and shapes the lenses to the customer's prescription, and then
assembles the glasses using the customer's choice of frame. The Specialty
Composites segment manufactures and sells a wide array of energy-absorbing
materials that are incorporated into other manufacturers' products to control
noise, vibration and shock.

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 Cabot Safety Corporation and certain affiliates (the
Predecessor), all of which were wholly owned by Cabot Corporation (Cabot), (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. 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. Separate financial statements of Aearo Company are not presented
because they do not provide any additional information from what is presented in
the consolidated financial statements of Aearo Corporation that would be
meaningful to the holders of the Senior Subordinated Notes (see Note 7).

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 reflect
carryover basis for the percentage ownership retained by Cabot.

(2) SIGNIFICANT ACCOUNTING POLICIES

The accompanying consolidated financial statements have been prepared in
conformity with accounting principles generally accepted in the United States.
All significant intercompany balances and transactions have been eliminated in
consolidation. The significant accounting policies of the Company are described
below.

     USE OF ESTIMATES

The preparation of the consolidated financial statements in conformity with
accounting principles generally accepted in the United States 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 consolidated financial statements and the reported amounts of
revenues and expenses during the reporting periods. Actual results could differ
from those estimates.

     RECLASSIFICATIONS

Certain amounts included in the prior years consolidated financial statements
have been reclassified to conform to the current year presentation. The
reclassifications have no impact on net income (loss) previously reported.

     REVENUE RECOGNITION

The Company recognizes revenue upon shipment of its products to customers.


                                       29

     ADVERTISING

The Company expenses the costs of advertising as incurred. These expenses were
approximately $4,827,000, $7,507,000 and $7,870,000 for the years ended
September 30, 1998, 1999 and 2000, respectively.

     CASH EQUIVALENTS

The Company considers all time deposits and short-term investments with an
original maturity of three months or less to be cash equivalents.

     FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS

Assets and liabilities of non-U.S. subsidiaries are translated at the exchange
rate as of the end of the year. Income and expenses are translated at the
approximate average exchange rates during the year. Foreign currency translation
adjustments are recorded as a separate component of stockholders' equity.
Foreign currency gains and losses arising from transactions by any of the
Company's subsidiaries are reflected in net income. For the years ended
September 30, 1998, 1999 and 2000 the accompanying consolidated statements of
operations include approximately $(617,000), $559,000 and $444,000,
respectively, of transaction (gains) losses included in other (income) charges,
net.

The Company enters into foreign currency forward exchange contracts to mitigate
the effects of changes in foreign currency rates on profitability related to
trade accounts receivable and trade accounts payable denominated in foreign
currencies. Gains and losses related to contracts designated as hedges of trade
accounts receivable and trade accounts payable denominated in foreign currencies
are accrued as exchange rates change and are recognized in the accompanying
consolidated statements of operations as transaction (gains) and losses and
included in other (income) charges, net. As of September 30, 2000, the Company
had forward foreign currency contracts open in the following amounts:

   Swedish Krona                70,572                    Buy
   Swiss Franc                   1,571                    Buy
   Euro                          6,930                    Sell
   Danish Krona                  2,240                    Sell
</TABLE>

As of September 30, 2000, the Company has recorded an unrealized gain of
$112,000 associated with the above forward foreign currency contract
commitments.

The Company enters into foreign currency forward exchange forward contracts to
hedge a portion of anticipated sales denominated in Great Britain Pound Sterling
and Euro to mitigate the impact of the effects of changes in foreign currency
rates on profitability related to cash flows from European operations. Gains and
losses on these hedge contracts are deferred and recognized as an adjustment to
the related sales transactions. Since 1999, the Company also entered into Euro
Zero Premium Collars and Euro Put Option contracts to mitigate the impact of the
effects of changes in foreign currency rates. Both the collar and option
contracts expired during the year ended September 30, 2000. For the year ended
September 30, 1999 and 2000, the consolidated statement of operations included
approximately $191,000 and $1,376,000 of gains related to these instruments.

The U.S. dollar equivalent notional amount of outstanding foreign currency
exchange forward contracts to hedge a portion of anticipated sales denominated
in Great Britain Pound Sterling and Euro is approximately $19.8 million at
September 30, 2000. Deferred losses related to hedges of future sales
transactions were approximately $344,000 at September 30, 2000. Contracts
outstanding at September 30, 2000 mature at various dates through September 30,
2001. The Company does not enter into these contracts for trading purposes.

     INVENTORIES

Inventories are stated at the lower of cost or market, cost being determined
using the first-in, first-out (FIFO) method.

     PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment is 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. Expenses for maintenance and repairs
totaled approximately $3,198,000, $2,902,000 and $2,928,000 for the years ended
September 30, 1998, 1999 and 2000, respectively.

Property, plant and equipment and the related estimated useful lives are as
follows:

                  ASSET CLASSIFICATION                                          ESTIMATED USEFUL LIFE
                  --------------------                                          ---------------------

                  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 consolidated financial statements, and any
resultant gain or loss is recognized.

     INCOME TAXES

Deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax basis of assets and liabilities using
currently enacted tax rates.

     INTANGIBLE ASSETS

Intangible assets consist primarily of goodwill, patents and trademarks
purchased in business acquisitions. Intangible assets are amortized over their
estimated useful lives.

Estimated lives by major category of intangible assets at September 30, 2000 is
as follows:

Goodwill                                    25 years
Patents                                     Life of patents (up to 17 years)
Non-compete agreements                      Life of agreements (up to 5 years)
Trademarks, tradenames and
Other                                       Varies from 15 to 25 years

     IMPAIRMENT

The Company accounts for long-lived and certain intangible assets in accordance
with Statement of Financial Accounting Standards (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 long lived and intangible assets for events
or changes in circumstances that 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 assets 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. During the year ended September 30, 2000, the Company
identified a certain information technology system that was impaired. As a
result, the Company wrote off approximately $500,000 related to this system,
which is included in other (income) charges, net.


     DEFERRED FINANCING COSTS


                                       31
<PAGE>   33


Deferred financing costs are stated at cost as a component of other assets and
amortized over the life of the related debt. Amortization of deferred financing
costs is included in interest expense and aggregated $1.9 million and $1.8
million for the year ended September 30, 1999 and 2000.

     FAIR VALUE OF FINANCIAL INSTRUMENTS

In accordance with the requirements of 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 and cash equivalents, accounts receivable,
accounts payable, Senior Subordinated Notes, bank debt (including term loans,
revolving credit facility and other debt) and interest rate swaps. The carrying
value of these assets and liabilities is a reasonable estimate of their fair
market value at September 30, 2000, except for the Senior Subordinated Notes,
for which the Company estimates the fair market value to be approximately $101.5
million at September 30, 2000, and except for interest rate swaps for which the
Company estimates the fair market value to be approximately ($100,000) at
September 30, 2000.

The Company also has off-balance sheet financial instruments in the form of
foreign currency forward exchange contracts as described in Note 2 to the
Consolidated Financial Statements. Current market prices were used to estimate
the fair value of the foreign currency forward exchange contracts.

The future value of the foreign currency forward exchange contracts and the
related currency positions are subject to offsetting market risk resulting from
foreign currency exchange rate volatility. The counter-parties to these
contracts are substantial and creditworthy financial institutions. Neither the
risks of counter-party non-performance nor the economic consequences of
counter-party non-performance associated with these contracts are considered by
us to be material.

     EARNINGS (LOSS) PER COMMON SHARE

SFAS No. 128, "Earnings per Share" requires presentation of basic and diluted
earnings per share on the face of the income statement. Basic earnings per
common share is computed by dividing net (loss) income by the weighted average
number of shares of common stock outstanding during the year. Diluted earnings
per share reflects the potential dilution that could occur if securities or
other contracts to issue common stock were exercised or converted. Potentially
dilutive securities consisted of stock options. As of September 30, 1998, 1999
and 2000 there were 7,154, 7,729 and 9,883 options outstanding, respectively.
The stock options were not dilutive and were not included in the diluted
earnings per share calculation for the years ended September 30, 1998, 1999 and
2000, respectively. Basic and diluted earnings per common share for the years
ended September 30, 1998, 1999 and 2000 were equal; therefore, no reconciliation
between basic and diluted earnings per common share is required.

     ACCOUNTING FOR STOCK-BASED COMPENSATION

SFAS No. 123 "Accounting for Stock-Based Compensation" addresses accounting and
reporting requirements for stock options and other equity instruments issued or
granted based on their fair market values. The Company intends to continue
accounting for its stock-based compensation plans for employees in accordance
with Accounting Principles Board Opinion (APB) No. 25, Accounting for Stock
Issued to Employees. Under SFAS No. 123, companies choosing to continue to use
APB No. 25 to account for stock-based compensation plans for employees must make
footnote disclosure of the pro forma effects on earnings per share, had the
principles contained within SFAS No. 123 been applied (see Note 12).

     COMPREHENSIVE INCOME (LOSS)

SFAS No. 130, "Reporting Comprehensive Income", requires the reporting of
comprehensive income (loss) and its components in the consolidated financial
statements. Comprehensive income (loss) includes net earnings and unrealized
gains and losses from currency translations. The components of the Company's
comprehensive (loss) income and the effect on earnings, for the three years
ended September 30, 2000, are detailed in the accompanying consolidated
statements of stockholders' equity.

     NEW ACCOUNTING PRONOUNCEMENT

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded


                                       32
<PAGE>   34


in other contracts. SFAS No. 133 is effective for fiscal years beginning after
June 15, 2000, and the Company adopted the provisions of SFAS No. 133 effective
October 1, 2000.

SFAS No. 133 requires that every derivative instrument be recorded in the
balance sheet as either an asset or a liability measured at its fair value. SFAS
No. 133 requires that as of the date of initial adoption, the difference between
the fair value of the derivative instruments recorded on the balance sheet and
the previous carrying amount of those derivatives be reported in net income or
other comprehensive income, as appropriate, as the cumulative effect of a change
in accounting principle in accordance with APB 20 "Accounting Changes".

The Company has foreign currency forward exchange contracts and interest rate
swap agreements, which are derivatives as defined by SFAS No. 133. The Company
enters into foreign currency forward exchange contracts to mitigate the effects
of changes in foreign currency rates on profitability and enters into interest
rate swap agreements to hedge their interest rate risk. These derivatives are
cash flow hedges. On October 1, 2000, the Company adopted the provisions of SFAS
No. 133 resulting in the recognition of a derivative liability and a
corresponding charge to other comprehensive income of approximately $450,000.
The adoption did not have a material impact on earnings.

Senior Bank Facilities

The Company's Senior Bank Facilities consist of Term Loans and a Revolving
Credit Facility as hereinafter defined. The Senior Bank Facilities consist of
(a) a secured term loan facility consisting of A and B term loans providing for
up to $90.0 million of A term loans and $50.0 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 $25.0 million of
revolving loans, a portion of which may be denominated in foreign currencies,
for general corporate purposes and, as to $15.0 million thereof, to finance
permitted acquisitions. The Revolving Credit Facility provides for the issuance
of letters of credit in an aggregate face amount of up to $5.0 million. Term A
and B Loans amortize quarterly over five-and-six-year periods, respectively.
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 until the Revolving Loan Maturity Date, which is May 30, 2002.

At the Company's option, the interest rates per annum applicable to the Senior
Bank Facilities are either (a) an adjusted rate based on the London Interbank
Offered Rate (LIBOR) 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 (b) 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 or the Overnight Federal Funds rate
plus 0.50%. The Company must pay certain fees in connection with the Senior Bank
Facilities, 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 a 0.25% facing fee relating to the
issuance of letters of credit.

(9) EMPLOYEE BENEFIT PLANS

The Company previously had two noncontributory defined benefit pension plans
(collectively, the Plans), the Aearo Company Employees' Retirement Account Plan
(the Aearo Plan), which is a cash balance plan, and the E-A-R(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. Effective December
31, 1997, net assets available for benefits totaling $1,499,027 held by the
Specialty Composites Plan were transferred to the Aearo Plan in a merger of the
two plans.

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 Specialty Composites Plan resulted from a 1989 acquisition. As
of March 31, 1989, the benefits under this plan were frozen. Plan assets were
invested in fixed-income investments. Benefits earned under the Specialty
Composites Plan are payable from the Aearo Plan. The Aearo Plan was amended to
incorporate the vesting, forms of payment, commencement dates and actuarial
equivalence provisions that existed in the Specialty Composites Plan immediately
prior to the merger, for purposes of determining such benefit. However, the
lump-sum present values of benefits accrued under the Specialty Composites Plan
will be based on the actuarial equivalence methodology specified in the Aearo
Plan.

In addition, the Company has an unfunded, noncontributory defined benefit
pension plan, the Aearo Company Supplemental Executive Retirement Plan (the SERP
Plan), which is also a cash balance plan. The SERP Plan, effective January 1,
1994, covers certain employees in the United States. The costs to the Company
for the SERP Plan were $61,000, $81,000 and $140,000 for the years ended
September 30, 1998, 1999 and 2000, respectively.

A 401(k) plan, the Aearo Company Employees' 401(k) Savings Plan, was established
as of May 1, 1990. Employees normally scheduled to work a minimum of 1,000 hours
per year can join the plan immediately and may contribute up to 15% of their
compensation. The Company contributes amounts equal to 50% of the employee's
contribution to a maximum of 3% of the employee's pay. Prior to January 1, 1997,
the Company provided a 40% match to a maximum of 2% of pay. The costs to the
Company for this Plan were $710,000, $765,000 and $857,000 for the years ended
September 30, 1998, 1999 and 2000, respectively.

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
2% of the employee's pay. For the years ended September 30, 1998, 1999 and 2000,
the Company contributed approximately $160,000, $197,000, and $198,000,
respectively.

Postretirement Benefits

The Company does not provide defined benefit postretirement plans for retirees
after age 65, except that 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.

(10) RELATED PARTY TRANSACTIONS

An annual management fee, which is to be shared by Cabot and Vestar, is 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 and totaled approximately
$434,000, $706,000 and $686,000 for the years ended September 30, 1998, 1999 and
2000, respectively.

The Company and Cabot have entered into an arrangement relating to certain
respirator claims asserted after the Formation Acquisition whereby, so long as
the Company pays to Cabot an annual fee of $400,000 as discussed in Note 13. The
Company paid Cabot $400,000 for each of the years ended September 30, 1998, 1999
and 2000.

The Company has made available to certain members of management (Management
Investors) loans 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. Such loans (i) are secured
by Common Stock purchased with the proceeds thereof, (ii) have a term of from
five to 10 years, (iii) bear interest at an annual rate determined pursuant to
Section 7872(f)(2) of the 1986 Internal Revenue Code, and (iv) are subject to
mandatory prepayment in the event the employment of such Management Investors
terminates. The aggregate amount of these loans was approximately $1,429,000 and
$1,496,000 at September 30, 1999 and 2000, respectively, and are reflected as a
reduction of the additional paid-in capital account in the consolidated
statements of stockholders' equity.

</TABLE>

The valuation allowance at September 30, 1999 and 2000 relates to the
uncertainty of realizing the tax benefits of reversing temporary differences and
net operating loss carryforwards. The gross amount of domestic and foreign net
operating loss carryforwards, before the tax effect, is approximately $28.6
million and $2.3 million, respectively, as of September 30, 2000. Of the
valuation allowance recorded as of September 30, 2000, approximately $7.1
million will be used to reduce goodwill related to the purchase if the benefits
are realized. During the current year, approximately $1.9 million of valuation
allowances originally established through purchase accounting have been reversed
through goodwill.

(12) STOCKHOLDERS' EQUITY

Stock Ownership and Stockholders' Agreement

As of September 30, 2000, Cabot owns 41.6% of common stock (42,500 shares) and
50% of redeemable preferred stock (22,500 shares), Vestar owns 41.6% of common
stock (42,500 shares) and 50% of redeemable preferred stock (22,500 shares) and
the Management Investors and certain other employees of the Company own 16.8% of
common stock (17,087.5 shares). Vestar, Cabot and the Management Investors are
parties to a stockholders' agreement (the Stockholders' Agreement). The
Stockholders' Agreement contains stock transfer restrictions, as well as
provisions granting certain tag-along rights, drag-along rights, registration
rights and participation rights.

The 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. To date, no dividends have been declared.
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 the Company at a redemption price equal to the
actual or implied purchase price ($45 million) plus a redemption payment based
on the dividend rate. As of September 30, 2000, the redemption value of the
preferred stock is $87,237,000.

Aearo Company is permitted to pay cash dividends to Aearo Corporation for taxes
and expenses in the ordinary course of business. The maximum amount of cash
dividends paid to Aearo Corporation for ordinary business expenses may not
exceed $500,000 in any fiscal year. As long as no event of default would result,
Aearo Corporation and Aearo Company are permitted to pay dividends consisting of
shares of qualified capital stock, as defined in the Senior Bank Facilities, and
Aearo Corporation may redeem or purchase shares of its capital stock held by
former employees of Aearo Corporation or any of its subsidiaries following the
termination of their employment, provided that the aggregate amount paid by
Aearo Corporation with respect to such purchases or redemptions does not exceed
$1.5 million; Aearo Company may pay cash dividends to Aearo Corporation for the
latter purpose. Additionally, Aearo Corporation may pay dividends on its
preferred stock in additional shares of preferred stock.

Stock Option Plans

On June 27, 1996, the Company adopted the Executive Stock Option Plan (the
Executive Plan) whereby the Company, subject to approval of the Board of
Directors, may grant up to 5,000 non-qualified options to certain members of
management. In July 1997, the Company's Board of Directors adopted and the
stockholders subsequently approved the 1997 Stock Option Plan (the "1997 Option
Plan") under which 10,000 shares of Aearo Common Stock have been reserved for


                                       40
<PAGE>   42


issuance. Under the 1997 Option Plan, non-qualified and qualified options may be
granted to employees of the Company. Options granted under the Executive Plan
and the 1997 Option Plan will vest and become exercisable upon the earlier of
the date on which a stipulated return (as defined) is achieved by Vestar and
Cabot on their investment in the Company or the tenth anniversary of the date of
grant. The option term will be 10 years, except that options shall expire in
certain instances of termination of employment and upon the sale of the Company.
As of September 30, 2000, a total of 9,882.5 options were outstanding under the
Executive Plan and 1997 Option Plan and a total of 5,117.5 options were
available for grant.

Pro Forma Stock-Based Compensation Expense

SFAS No. 123, Accounting for Stock-Based Compensation, sets forth a
fair-value-based method of recognizing stock-based compensation expense. As
permitted by SFAS No. 123, the Company has elected to continue to apply APB No.
25 to account for its stock-based compensation plans. Had compensation cost for
awards granted in 1998, 1999 and 2000 under the Company's stock-based
compensation plans been determined based on the fair value at the grant dates
consistent with the method set forth under SFAS No. 123, reported net (loss)
income and net (loss) income per share would not have been affected for 1998,
1999 and 2000.

The fair value of each option grant was estimated on the grant date using the
Black-Scholes option pricing model with the following weighted average
assumptions:

<TABLE>
<CAPTION>
                                                   1998            1999           2000

Risk-free interest rate                              5.52%           4.99%          6.01%
Expected life of options granted                 10 years        10 years       10 years
Expected volatility of underlying stock                 0%              0%             0%
Dividend yield                                          0%              0%             0%
</TABLE>


The Black-Scholes option pricing model was developed for use in estimating the
fair value of traded options, which have no vesting restrictions and are fully
transferable. In addition, option pricing models require input of highly
subjective assumptions, including expected stock price volatility. Because the
Company's stock options have characteristics significantly different from those
of traded options and because changes in the subjective input assumptions can
materially affect the fair value estimate, in management's opinion, the existing
models do not necessarily provide a reliable single measure of the fair value of
the Company's stock options.

Contingencies

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 AO
Safety(R) Division from American Optical Corporation 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 the opinion of management of the Company, these suits and claims
should not result in final judgments or settlements that, in the aggregate,
would have a material adverse   effect on the Company's financial condition or
results of operations.

As part of a trademark dispute with Moldex-Metric, Inc. involving the Company's
"Yellow Neon Blasts"(TM) polyurethane earplugs, a federal district court in
Southern California issued a preliminary injunction in October, 2000 which
required the Company to immediately withdraw the current version of "Yellow Neon
Blasts"(TM) polyurethane earplugs from the U.S. market, and to advise its
distributors to withdraw this product from the market, until the trademark issue
could be resolved. In accordance with this ruling, the Company ceased the
manufacturing and distribution of "Yellow Neon Blasts"(TM). The Company appealed
the preliminary injunction and the court granted a stay of the injunction
pending appeal to the Ninth Circuit. "Yellow Neon Blasts"(TM) was introduced
approximately one year ago as part of the Company's new line of polyurethane
earplugs called E-A-Rsoft(TM). Over the past twelve months, "Yellow Neon
Blasts"(TM) has accounted for approximately $1 million of the Company's U.S.
sales (the trademark dispute and the preliminary injunction do NOT include the
E-A-Rsoft(TM) "Yellow Neons"(TM) solidly colored earplugs or any other Company
products). In December, 2000 the Company reached a non-cash settlement with
Moldex-Metric, Inc. whereby the "Yellow Neon Blasts"(TM) would be taken off the
market in the U.S. and Canada. In the opinion of management, this will not have
a material impact on operations.

allocated to goodwill.

On June 1, 2000, the Company acquired Norway based Livax A/S for approximately
$0.3 million. The transaction was accounted for using the purchase method of
accounting, and accordingly, the operating results of Livax have been included
with those of the Company subsequent to June 1, 2000.

On August 2, 1999, the Company acquired Safety Optical, Inc. of Athens,
Tennessee. 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 August 2, 1999
reflect the purchase price, including transaction costs, allocated to tangible

</TABLE>

The Company evaluates performance of its operating entities based on EBITDA,
which is defined by the Company as earnings before interest, taxes,
depreciation, amortization, and non-operating income or expense. Non-operating
income or expense is further defined by the Company for EBITDA purposes as
extraordinary gains or losses, or gains or losses from sales of assets other
than in the ordinary course of business. While the Company believes EBITDA is a
useful indicator of its ability to service debt, EBITDA should not be considered
as a substitute for net income determined in accordance with accounting
principles generally accepted in the United States as an indicator of operating
performance or as an alternative to cash flow as a measure of liquidity.
Investors should be aware that EBITDA, as presented above, may not be comparable
to similarly titled measures presented by other companies and comparisons could
be misleading unless all companies and analysts calculate this measure in the
same fashion.

Intersegment sales of the Specialty Composites segment to the Safety Products
segment totaled $4,635 and $3,890 for the years ended September 30, 1999 and
2000, respectively. The intersegment sales value is generally determined at
fully absorbed inventory cost at standard rates plus 25%.

Reconciling items include unallocated selling, administrative, research and
technical expenses as well as manufacturing profit realized on intercompany
transactions not allocable to a specific segment. Reconciling items for 1998
include $10,550 for restructuring and restructuring related items primarily
attributed to the safety products segment.

(1)  There was no public market for the Aearo Common Stock as of September 30,
     2000. Accordingly, these values have been calculated on the basis of an
     assumed fair market value of $600 per share as established by the Company's
     Board of Directors.
(2)  Mr. Carey, although no longer an executive officer of the Company, has
     retained his options to acquire shares, pursuant to certain terms of the
     stock option plans and to the terms of his separation agreement.

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 appointed in prior fiscal years have been given
the opportunity to purchase a limited number of shares of Aearo Common Stock. No
Outside Directors were appointed to the Board during fiscal 2000. Outside
Directors may also elect to participate in the Deferred Compensation Plan.


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, 15,000
shares of Aearo Common Stock have been reserved for purchase by the Company's
executive officers and other senior members of management as determined by the
Board of Directors. As of December 1, 2000, 11,273 of such shares were issued
and outstanding.

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."

STOCK OPTION PLANS. 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. In July 1997, the Company's Board of Directors adopted
and the stockholders subsequently approved


                                       52
<PAGE>   54


the 1997 Stock Option Plan (the "1997 Option Plan") under which 10,000 shares of
Aearo Common Stock have been reserved for issuance. Under the 1997 Option Plan
non-qualified and qualified options may be granted to employees of the Company.

Each of the Executive Plan and the 1997 Option Plan is administered by a
committee of the Board of Directors consisting of all non-employee directors. As
of September 30, 2000, non-qualified options to acquire 8,417 shares at a price
of $600 per share, and 1,466 shares at a price of $800 per share have been
granted to officers and key employees of the Company under the Company's stock
option plans and 5,118 options remain available for issuance; of outstanding
options, 3,068.75 in the aggregate have been granted to executive officers,
including Mr. McLain (1,100 options), Mr. Warren (750 options), Mr. Hall (400
options), former executive officer Mr. Carey (562.5 options) and Mr. Mallitz
(256.25 options). 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 (but did not
expire upon the termination of employment of Mr. Carey, as permitted under the
terms of the stock option plan in certain instances and as provided in his
separation agreement), 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
or 1997 Option 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."

The following table sets forth certain information relating to option grants
pursuant to the Executive Plan and the 1997 Option Plan for the year ended
September 30,2000.

(1) Potential Realizable Value is based on assumed growth rates for the 10 year
option term (5% annual growth results in a stock price of $930.80 and 10% annual
growth rate results in a stock price of $1,414.77).


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 severance pay policy
providing certain executive officers and key employees with salary continuation
in the event of a termination. The plan generally provides for one month's base


                                       53
<PAGE>   55


pay for each full year of service with a minimum amount payable of three months
and a maximum amount payable of twelve months.

DEFERRED COMPENSATION PLAN. The Company has adopted a Deferred Compensation Plan
which is a non-qualified savings plan under the IRS code and which provides
officers and paid directors the opportunity to defer the receipt of base salary
and/or bonus. The plan is effective for fiscal years beginning with fiscal year
2000 and provides unfunded deferred compensation payments upon a participant's
retirement or termination from the Company. Participant deferrals are credited
annually with amounts based upon long-term bond rates and with amounts
replicating the Company match in the 401(k) for savings from income above the
qualified plan limits.

401(k) PLAN. The Company has adopted a savings plan (the "Savings Plan"), which
is qualified under Section 401(a) and 401(k) of the Code. All regular employees
of the Company in the United States normally scheduled to work a minimum of
1,000 hours per year are eligible to participate in the Savings Plan
immediately. 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 50.0% of the first 6.0% of compensation contributed. The maximum
contribution for any participant for any year is 15.0% of such participant's
eligible compensation, not to exceed the 401(k) plan elective deferral limit set
forth by the IRS. Contributions to the Savings Plan will be invested, as the
employee directs, in a money market fund, income fund, growth and income fund,
growth fund, or asset allocation fund.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
ARRANGEMENTS
Effective January 23, 1998, the Company entered into an agreement with Michael
A. McLain which covers the terms and conditions of his employment. It contains a
provision for separation benefits in the event of a change of control or other
termination not related to performance.


                                       54
<PAGE>   56


PENSION PLANS. The Company has adopted a cash balance plan. Under such plan, the
Company will provide participants with annual credits of 4.0% of eligible
compensation up to the Social Security Wage Base as set forth annually by the
Social Security Administration and Department of Health and Human Services. An
additional annual credit of 8.0% of eligible compensation from the Social
Security Wage Base up to the Qualified Plan Compensation Limit set forth by the
Internal Revenue Service (IRS) is provided. All balances in the accounts of
participants will be credited with interest based on the prior year's 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.

Additionally, 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 individuals whose salary exceeds the
Qualified Internal Revenue Service (IRS) Plan Compensation Limit set forth by
the IRS. Pursuant to the plan, participants are credited annually with amounts
representing 8% of compensation in excess of the Qualified Plan Compensation
Limit.

The following table sets forth, for the Named Executive Officers, the estimated
annual benefits payable upon retirement at normal retirement age, from both the
qualified and non-qualified pension plans assuming in each case that such
officer elects payment over time rather that in a lump sum:

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 sold 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.

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. As of December 1, 2000, (i) Cabot indirectly owns 41.6% of the Aearo
Common Stock outstanding and 50% of the Aearo Preferred Stock outstanding, (ii)
Vestar owns 41.6% of the Aearo Common Stock outstanding and 50% of the Aearo
Preferred Stock outstanding and (iii) 16.8% of the Aearo Common Stock has been
issued to management and certain directors (collectively the Management
Investors). 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 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 will have the power 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, and the Management Investors 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. Currently there
are nine directors serving. 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


                                       57
<PAGE>   59


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
Acquisition 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. Rothberg and Ms. Hanratty were designated by Cabot as
described in clause (ii) above, Messrs. Kassling and Marsal were designated by
Vestar as described in clause (iii) above and Mr. McLain and Mr. Curtin 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
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


                                       58
<PAGE>   60


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
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.

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. Pursuant to the Management
Advisory Agreement, each of Vestar and Cabot received $342,838 (including
$24,080 to each party as an advisory fee relative to fiscal year 1999) with
respect to 2000, $352,806 (including $58,144 to each party as an advisory fee
relative to fiscal year 1998) with respect to fiscal 1999, $217,063 (including a
$19,456 reduction to each party as an advisory fee adjustment for fiscal 1997)
with respect to fiscal 1998, $311,949 (including $55,975 to each party as an
advisory fee adjustment relative to fiscal 1996) with respect to fiscal 1997.

O'Connell and Nagle, three of the directors of the Company, are affiliated with
Vestar in the capacities described under Item 10, "Directors and Executive
Officers" and, accordingly, benefit from any payments received by Vestar. Mr.
Rothberg and Ms. Hanratty, two of the directors for the Company, are affiliated
with Cabot in the capacities described under Item 10, "Directors and Executive
Officers" and, accordingly, benefit indirectly from any payments received by
Cabot.

MANAGEMENT AND DIRECTOR LOANS. The Company has made available to certain
Management Investors loans 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. 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 between 6.31% and 7%, and (iv) are subject to mandatory prepayment in the
