Part I

ITEM 1. BUSINESS

(a) General development of business:

CUNO Incorporated ("CUNO" the "Company", or "we") is a world leader in the
designing, manufacturing and marketing of a comprehensive line of filtration
products for the separation, clarification and purification of liquids and
gases. Our products, which include proprietary depth filters and semi-permeable
membrane filters, are used in the potable water, fluid processing, and
healthcare markets. These products, most of which are disposable, effectively
remove contaminants that range in size from molecules to sand particles. Our
sales are balanced between domestic (approximately 55%) and international
markets (approximately 45%).

Our objective is to provide high value-added products and premium customer
service. Our proprietary manufacturing processes result in products that lower
customers' operating expenses and improve the quality of customers' end products
by providing longer lasting, higher quality and more efficient filters. As part
of our commitment to customer service, we designate our own scientists, each of
whom possess particular industry expertise, to collaborate with customers on
specific projects to insure satisfaction with its products and to create new
products.

Our success is partially dependent on the development and implementation
of the following initiatives, which are key elements of our ongoing growth
strategy: (i) develop new products for specific markets, (ii) decrease product
development cycle times, (iii) develop pre/final filter systems, (iv) increase
customer satisfaction, (v) improve operating efficiencies, and (vi) pursue
selective acquisitions.

(b) Financial information about industry segments:

The Company is divided into five geographic operating segments, each of
which has general operating autonomy over its products and local operations.
These operating segments are as follows: North America, Europe, Japan,
Asia/Pacific, and Latin America. See Note 9 - Segment Financial Data on pages
30-32 of the 2002 Annual Report to Stockholders which is incorporated herein by
reference.

(c) Narrative description of business:

OVERVIEW: Filtration is the process of separating particles of various sizes
from liquids or gases. The mechanics of filtration range from the removal of
coarse contaminants, most often particulates, as large as 200 microns such as
sand and sediment, to the elimination of bacteria and viruses at less than .01
micron (human hair is typically 20 microns in diameter). A filtration device
consists of a plastic or metal housing and a filtration medium. Filtration
media, which can be manufactured out of a variety of substances, act as the
separator or barrier in the filtration process.

Filtration media include microporous membranes, glass, synthetic and
cellulosic fibers, porous metals and ceramics. Microporous membranes are thin,
film-like materials with millions of uniform microscopic holes. Membranes are
the most widely used filtration media because they remove specifically-sized
particles and can be configured into a variety of shapes and sizes. Each of
CUNO's five operating segments manufacture and sell products into the potable
water, fluid processing, and healthcare markets.

OPERATING SEGMENTS: We serve three primary markets from a geographical operating
structure. Each of our five operating segments (North America, Europe, Japan,
Asia/Pacific, and Latin America ) manufacture and sell products into the potable
water, fluid processing, and healthcare markets. These markets represent the end
markets in which the customers reside. Since the nature and attributes of the
markets vary widely by geographic region, to best address these markets we have
established a management structure based upon geography. The management for


2

each of the geographic regions operate independent sales and manufacturing
organizations that function within an overall corporate framework of strategic
initiatives and performance targets. The majority of these initiatives and
targets are established to best address the three major markets and to achieve
the financial objectives of the business. Further detail on our three major
markets follows:

Potable Water: The potable water market includes residential,
commercial, and food service customers. According to industry data, it is
estimated that one billion people in the world do not have safe drinking water.
Demand is driven both by consumers' desire to improve the taste and quality of
their drinking water and by the expanded concern of regulatory agencies. North
American sales have increased sharply since 1999 due primarily to exceptional
growth in new appliance filters for the OEM market and, to a lessor extent, as a
result of the successful assimilation of certain small acquisitions. Growth
potential appears especially strong in Asia/Pacific and Latin American countries
where the quality of drinking water has been found to be severely deficient in
several regions. Water safety concerns have driven the growth of the consumer
bottled water market to over $2 billion in the United States, as well as the
growth in the water filtration market.

The food service industry has an increasing need for consistent global
product quality. Food service includes water used for fountain beverages, steam
ovens, coffee and tea (i.e. "recipe quality water"). Specifically, restaurants
have become increasingly aware of the need for water filtration to control the
taste and quality of the water used in their businesses. Worldwide sales to the
potable water market totaled $119,456,000, $107,263,000, and $101,483,000 in
2002, 2001, and 2000, respectively.

Fluid Processing: Major customers in the fluid processing market
include chemical, petrochemical and oil and gas processors, manufacturers of
paints and resins, producers of electronics and semi-conductors, and power
generation facilities. As sophisticated manufacturing processes increase and as
the adoption of practices focused on quality increase, we believe the demand for
filtration products will also increase. In part, this trend is driven by the
enhanced ability to detect contaminants in process streams. As automation
increases, focus on quality control increases, and as the ability to detect
contaminants progresses, fluid filtration will play a greater role in the
manufacturing process.

A significant segment of our fluid processing market is electronics
manufacturing. Ultra pure water is used to rinse the components during
manufacturing in order to ensure that the product is particle free with no
residual contamination. The industry uses corrosive, high purity chemicals and
gases for the manufacture of computer chips, hard disks, video terminals and
other components. All of the chemicals and gases used are processed through very
fine filtration systems. The strengthening demand for electronic products and
oil and gas products has helped recent sales growth, and certain new products
are expected to stimulate growth in the future. Sales to the fluid processing
market totaled $68,714,000, $71,898,000, and $78,781,000 in 2002, 2001, and
2000, respectively.

Healthcare: The healthcare market is experiencing rapid growth as a result
of the intensive research efforts to find cures for diseases, the increasing use
of rapid and simpler diagnostic tests to help reduce healthcare costs, the trend
toward finer and more cost-efficient filtration and increased governmental
regulation. When harmful elements are identified, they are often regulated or
new medical standards of care are implemented to decrease or eliminate contact.
In many cases, fluid filtration can play a key role in eliminating contact with
many harmful elements. Price is not the primary factor in the customers'
filtration decision process, but rather the performance and reliability of the
product.

Our healthcare market customers include pharmaceutical and biotechnology
companies that require cost-efficient filtration and high levels of purity for
production of sterile, contaminate free drugs, as well as producers of
diagnostic test kits which require highly efficacious membranes. In addition,
applications include the production of bacteria-free water and food and beverage
products. Sales to the healthcare market totaled $70,031,000, $65,288,000, and
$62,810,000 in 2002, 2001, and 2000, respectively.

GROWTH STRATEGY: Our goals are to grow at a rate higher than the general
filtration market, expand our market share and to increase our operating margins
and profitability. Key elements of our growth strategy include:

Develop New Products for Specific Markets. We have initiated a strategy to
develop high value-added products for specific markets. Historically, we offered
non-differentiated products and often competed solely on price. To gain a better
understanding of specific markets and guide new product development, we
introduced Scientific Application Support Services ("S.A.S.S."). S.A.S.S. uses
scientists with post-graduate degrees who are experts in the specific industry
they serve. They collaborate with customers who are developing and implementing
new processes or products that have specific filtration requirements. Often
these relationships lead to the development of new market-specific products.

Decrease Product Development Cycle Times. We have decreased our product
development cycle times to approximately 18 to 24 months. This improvement has
occurred through increased market focus, collaboration with leading-edge
customers through S.A.S.S. teams and the formation of cross-functional product
launch teams. We believe we can continue to shorten product development cycle
times through these same methods.

Develop Pre/Final Filter Systems. Many filtration systems have one or more
pre-filters to remove large contaminants from the liquid or gas before it passes
through the final filter, prolonging the life of the more expensive final
filter. When these filters are designed together in a system, the performance of
the system is enhanced. We have a leading pre-filter market position and are
expanding the number of final filters we offer. This allows the Company to
provide its customers with a total filtration solution from one vendor.

Increased Customer Focus. We have traditionally sold to distributors, who
in turn sell to the end user. Our current goal is to provide unmatched customer
service to our end-user customers, while providing resources to our
distributors. In many cases the customer is unable to define its filtration
needs accurately and seeks outside resources to identify and choose the best
filtration alternative. Our S.A.S.S. professionals meet this need. Management
has been training and focusing distributors on specific market segments and
providing additional training, sales, and marketing support. This enables
distributors to provide customers with superior industry expertise and
company-specific product knowledge.

Improve Operating Efficiencies. We believe we can improve operating
efficiencies by offering higher margin new products and implementing cost
controls, supply chain management, productivity gains, profit-based compensation
programs and outsourcing production of certain processes. We have initiated a
capital investment program designed to (i) integrate cell-based manufacturing,
(ii) provide higher yields from raw materials, (iii) improve inventory
management, (iv) lower labor costs, (v) reduce manufacturing cycle times, and
(vi) reduce scrap rates.

Pursue Selective Acquisitions. We review opportunities to acquire
high-quality companies which will allow us to expand into new geographic
markets, add new customers, provide new products, manufacturing and service
capabilities or increase our penetration with existing customers.

In fiscal 2002, we completed a product line acquisition in Australia and a
distributor acquisition in Europe for total consideration of $700,000. The
amount of goodwill and other intangibles recorded in connection with these
acquisitions amounted to $250,000 and $244,000, respectively.

In the second quarter of fiscal 2001, we closed on two acquisitions - a
product line in Australia and a distributor in Europe -- for a total cost of
$4.5 million. These acquisitions did not have a material effect on the our
historical financial statements or pro forma operating results. In the second
quarter of fiscal 2000, we made a contingent consideration payment of $2.9
million related to the previous acquisition of Chemical Engineering Corporation
(CEC). This payment was recorded as additional goodwill. There will be no future
contingency payments related to the CEC acquisition. The acquisition of CEC
included certain life insurance policies on key


4

officers of CEC. In the second quarter of 2000, we elected to surrender these
policies for their cash surrender value upon settlement.

PRODUCTS: We manufacture a full range of products by offering our customers
solutions to a wide range of filtration requirements. Many of the products
manufactured by us use electrokinetic adsorption, a proprietary chemical process
we developed which alters both membrane and depth filter media surfaces.
Electrokinetic adsorption uses molecular charges on dissolved ions to bind finer
contaminants to the filter surface. This attribute significantly enhances
filtration efficiency by removing contaminants smaller than the micron rating of
the filter. We typically group our products into the following categories:

Membranes: The typical polymer and nylon membranes that we produce
resembles plastic films except for the molecular size pores that are engineered
into the surface and depth of the membrane. By varying pore size and altering
the physical or chemical properties of the membrane, the quantity and type of
substances which can pass through the membrane can be regulated with absolute
certainty. We manufacture "absolute rated" products where no particle above a
certain size can pass through the membrane. In many applications, these
membranes can be integrity tested to ensure specific performance both at the
beginning and end of a particular process. A membrane can be employed in a
variety of configurations, including flat sheets, discs and cartridges that
contain high surface area and pleated membrane media.

Uses of membranes include water purification for electronics and
applications in semiconductor manufacturing, pharmaceutical, biotechnology and
other applications, as well as residential use for drinking water.

Our products include those sold under the following labels: Zetapor(R),
Microfluor (R), PolyPro(R), Zetabind(R), Electropor(R)II, BevASSURE(R),
MaxMedia(TM), Synchro(R), Acro(R), AC/PH Lithowater(R), and LifeASSURE(R).

Depth Filters: Our disposable depth filters are constructed from a matrix
or formation of very fine and micro-fine fibers such as polypropylene, cotton,
polyester, glass fiber, acrylic, rayon, polymer, carbon and other materials. The
fibre matrix is then processed into a rigid filter media using techniques such
as thermal bonding, resin bonding, pleating or winding. Our technology has a
strong emphasis on graded density attributes and electrokinetic adsorption.
Graded density depth technology allows filter media to be manufactured with very
open porous outer layers, progressively becoming smaller in the size of the
pores or void volume through the depth of the filter media. Graded density
construction extends filter life in many applications and reduces pressure loss
across the filtration process thereby reducing energy costs. The structure of
graded density filter media allows particles to be trapped throughout the depth
of the cartridge which minimizes surface binding, allows for high contaminant
capacity and lower pressure drops than solely trapping particles on the surface
of the media.

We manufacture depth filters in a wide variety of cartridge and pore sizes
with "absolute" particulate ratings. The filter cartridges are used in filter
housings that can be manufactured in a broad range of metals or plastics to suit
particular customer specifications. Filter housings are designed for a wide
range of temperatures and pressures.

Our depth filter products include those sold under the following labels:
Zeta Plus(R), Betafine(R), Micro-Klean(R) III, Beta-Klean(R), Betapure(R),
PolyNet(TM) , BioCap(R), Micro-Wynd(R) II, Econo-Klean(R), Virosorb(R),
Petro-Klean(R), Delipid(R), SterASSURE(TM), Zetacarbon(R), and Novylon(R).

Cleanable Filters and Systems: We design and manufacture an extensive
range of self-cleaning disc filters, backwash strainers and recleanable metal
filters. The self-cleaning disc filters and backwash strainers can be
electrically or mechanically operated with automatic controls to provide for
specific requirements in process applications. The recleanable metal filter
elements are constructed of sintered porous stainless steel or metal screens in
tubular and pleated construction. The recleanable elements can be cleaned in
place in a filter housing or removed for mechanical, ultrasonic or chemical
cleaning.

Our cleanable filters and system products include those sold under the
following labels: Poro-Klean(R), Micro-Screen(R), and Auto-Klean(R).

Housings and Systems: We design and manufacture a wide variety of filter
housings to suit specific process and customer applications. The housings can be
of plastic or metal construction utilizing a broad range of materials including
polypropylene, PVC, nylon, aluminum, copper, brass, steel, stainless steel and
other specialized metals, such as titanium.

Specialized designs include sanitary, electropolished and coated finishes
for chemical resistance and ease of sterilization, sanitization or cleaning. We
supply a broad range of standard housings manufactured from type 316 stainless
steel in sanitary, polished and electropolished finishes for enhancing
pharmaceutical and electronic applications. Finish specifications can be
measured in terms of Roughness Average (Ra) with average variations in surface
finish measured in microns down to 0.45 micron, the size of small bacteria.

We design and manufacture proprietary housings and systems such as
CTG-Klean(TM) with patented features and a totally enclosed disposable filter
media pack for use in critical applications where housing cleanliness is
essential or when physical separation of toxic or corrosive chemicals from the
metal housing is desired.

Our range of housings are designed and manufactured to regulatory pressure
vessel codes, particularly for applications in the oil and gas, refinery and
petrochemical industries. We design and market housings to meet the local
regulatory requirements in most countries.

BACKLOG: Our backlog on October 31, 2002 was $18.2 million as compared to $16.5
million as of the same date the previous year. Due to the relatively short
manufacturing cycle and our use of wholesale distributors as well as general
industry practice, backlog, which typically represents less than 30 days of
shipments, is not deemed to be significant. A substantial portion of our
revenues result from orders received and product sold in the same month.

COMPETITION: The markets in which we compete are highly competitive. We compete
with many domestic and international filtration companies in our global markets
including some which are larger and which possess greater resources. No one
company has a significant presence in all of our markets. The principal methods
of competition are product specifications, performance, quality, knowledge,
reputation, technology, distribution capabilities, service and price. Some of
our other competitors are multi-line companies with other principal sources of
income, some of which have substantially greater resources than the Company.
Other competitors are local product assemblers or service companies that
purchase components and supplies such as valves and tanks from more specialized
manufacturers. Through our S.A.S.S. teams, we have developed many products by
collaborating with our customers throughout the design and development process.
We believe that these relationships provide us with a competitive advantage over
other manufacturers.

RESEARCH AND DEVELOPMENT: Our research, development, and engineering activities
are conducted in our own laboratories, supplemented by on-site development and
application of custom design and other technical skills. Our research,
development and engineering expenditures, which consisted mainly of the
development of new products, product applications and manufacturing processes
for fiscal year 2002, 2001, and 2000 were approximately $14.7, $13.7, and $12.9
million, respectively, and 5.7 percent, 5.6 percent, and 5.3 percent of net
sales, respectively. We also incur additional internal costs relating to our
sales and service personnel for product development.

MANUFACTURING: Our manufacturing is largely vertically integrated, using unique,
proprietary and patented processes, with many of the major components of our
filtration units manufactured and assembled in our own plants. We have begun to
outsource a limited amount of our manufacturing processes, such as segments of
metal housing manufacturing. We believe that we generally have sufficient
manufacturing capacity for the foreseeable future. We have developed a new, more
efficient membrane manufacturing process that we believe provides a competitive


6

advantage through the production of superior products at lower costs. Other than
our new facility in China, all of our manufacturing facilities are ISO 9002
certified.

RAW MATERIAL SUPPLIERS: The primary raw materials used by the Company are
cotton, nylon, acrylic, cellulose, resins, plastics and metals. We have not
experienced a shortage of any of our raw materials in the past three years. We
believe that there is an adequate supply of all of our raw materials at
competitive prices from a variety of suppliers.

DISTRIBUTION AND SALES: We have approximately 150 independent distributors of
our products in 65 countries. Distributors represent the primary channel in the
marketing of our healthcare and fluid processing products. We have agreements
with all of our major distributors in the United States. In certain markets
outside the United States, we use dedicated sales people. Our potable water
products are sold directly to wholesalers, such as plumbing suppliers, water
quality dealers and major resellers, and through manufacturing representatives.

Agreements with our United States distributors are usually for a period of
two years. Such agreements usually assign an exclusive territory, prohibit
distributors from carrying competing products, require that distributors share
market and customer related information other than pricing with us, and require
distributors to carry an adequate stock of our products. We do not believe that
the loss of any one of our distributors would have a significant adverse effect
on the Company. Our top ten customers accounted for approximately 30 percent of
our total sales in fiscal year 2002.

Whirlpool accounted for approximately 13.2 percent of fiscal 2002 sales
and 11.5 percent of fiscal 2001 sales. We believe that no other customers
account for more than ten percent of sales. As of October 31, 2002, the Company
employed approximately 400 people as sales people. Of such employees,
approximately 260 are located overseas.

TRADEMARKS AND PATENTS: Trademarks and brand name recognition are important to
the Company. We generally own the trademarks under which our products are
marketed. We have registered our trademarks and will continue to do so as they
are developed or acquired. We have approximately 390 registered trademarks
throughout the world.

We have approximately 290 active patents throughout the world and more
than 300 patent applications pending worldwide. Additionally, we rely on
proprietary, non-patented technologies to a certain extent. Certain of our
employees sign non-disclosure and assignment of proprietary rights agreements.

We protect our intellectual property and believe there is significant
value associated with it. However, we believe that the loss of one or more of
our trademarks and patents would not have a material adverse effect, as we are
not heavily dependent on any one or few and we are continually expanding our
intellectual estate through new additions.

SEASONALITY: Our business is typically not seasonal. However, sales in the first
quarter of each fiscal year tend to be lower than the other quarters due to the
holiday season and year-end distributor inventory reductions.

GOVERNMENT REGULATIONS: We believe that we are in substantial compliance with
applicable regulations of Federal, state and local authorities regulating the
handling of specified substances and the discharge of materials into the
environment.

We manufacture certain filtration products that are used as components in
medical devices and we must use the Food and Drug Administration ("FDA") listed
materials in the manufacture of these products. Additionally, we maintain Drug
Master File ("DMF") files on certain products sold into the health care market.

Certain medical devices marketed and manufactured by our customers are
subject to extensive regulation by the FDA and, in some instances, by foreign
governments. Noncompliance with FDA requirements can result in,


7

among other things, fines, injunctions, civil penalties, recall or seizure of
products, total or partial suspension of production, failure of the government
to grant pre-market clearance or pre-market approval for devices, withdrawal of
marketing approvals and criminal prosecution. Before a new device can be
introduced into the market, the manufacturer must generally obtain FDA clearance
through either a 510(k) notification or pre-market approval application ("PMA").
A 510(k) clearance will be granted if the submitted information establishes that
the proposed device is "substantially equivalent" to a legally marketed Class I
or II medical device, or to a Class III medical device for which the FDA has not
called for PMAs. The FDA recently has been requiring a more rigorous
demonstration of substantial equivalence than in the past. It generally takes
from four to twelve months from submission to obtain a 510(k) clearance, but it
may take longer. The FDA may determine that a proposed device is not
substantially equivalent to a legally marketed device, or that additional
information is needed before a substantial equivalence determination can be
made.

In many areas the sale and promotion of water treatment devices is
regulated at the state level by product registration, advertising restrictions,
water testing, product disclosure and other regulations specific to the water
treatment industry. In some local areas certain types of water treatment
products, including those manufactured by us, are restricted because of a
concern with the amount and type of contaminants per volume of water they
discharge as locally regulated.

ENVIRONMENTAL MATTERS: Compliance with foreign, Federal, state and local laws
and regulations enacted to regulate the handling of and the discharge of
specified materials into the environment has not had, and is not expected to
have, a material effect upon our business.

EMPLOYEES: At October 31, 2002, we employed approximately 1,650 people worldwide
(exclusive of employees of independent distributors), with over approximately
875 employees in the United States and approximately 775 employees in other
countries.
