Item 1. Business

(a) General Development of Business

   The Company's business began as a one-product, one-country operation that
has become a multinational supplier of a broad line of dispensing packaging
systems. The Company's business was started in the late 1940's through its
subsidiary SeaquistPerfect Dispensing L.L.C., which manufactured and sold
aerosol valves in the United States. The Company's business has grown
primarily through the acquisition of relatively small companies and internal
expansion.

(b) Financial Information about Industry Segments

   The Company operates in the packaging components industry. Financial
information relating to operations by geographic area for each of the three
years in the period ended December 31, 2000 is set forth in Note 16 ("Segment
Information") to the Consolidated Financial Statements contained in the 2000
Annual Report to Stockholders, pages 48 and 50, which is incorporated herein
by reference.

(c) Narrative Description of Business

General

   The Company is a leading global supplier of a broad range of innovative
dispensing systems for the personal care, fragrance/cosmetic, pharmaceutical,
household and food/beverage markets. The Company focuses on providing value
added dispensing systems (pumps, dispensing closures and aerosol valves) to
global consumer product marketers to allow them to differentiate their
products and meet the consumer's need for convenience. The Company has
manufacturing facilities located throughout the world including facilities in
North America, Europe, Asia and South America. The Company has over 2,500
customers with no single customer accounting for greater than 6% of the
Company's 2000 net sales.

   For 2000, the percentage of net sales represented by sales to the personal
care, fragrance/cosmetic, pharmaceutical, household and food/beverage markets
were 32%, 32%, 21%, 8% and 7%, respectively. Pumps, dispensing closures and
aerosol valves represented approximately 62%, 22% and 14%, respectively, of
AptarGroup's 2000 net sales. The Company expects the mix of sales by product
and by market to remain approximately the same in 2001.

   Sales of a majority of the Company's dispensing systems have traditionally
grown at a faster rate than the overall packaging industry as consumer's
preference for convenience has increased, and product differentiation through
packaging design has become more important to the Company's customers.
Consumer product marketers have converted many of their products to packages
with dispensers that offer the benefit of enhanced shelf appeal, convenience,
cleanliness or accuracy of dosage. The Company expects this trend to continue.

Growth Strategy

   The company intends to enhance its position as a leading global supplier of
innovative dispensing systems by (i) expanding geographically, (ii)
discovering new applications for the Company's existing products, and (iii)
developing new dispensing technologies.

   The Company is committed to expanding geographically to serve multinational
customers in existing and emerging areas. Targeted areas include Latin
America, Eastern Europe, India and Asia. Recently, the Company acquired a
minority interest in a leading manufacturer of dispensing closures in
Argentina, and is in the process of increasing its manufacturing capabilities
in India, China and Eastern Europe.

   The Company continues to develop applications for SimpliSqueeze(R), a no-
leak, invertible closure with one-hand dispensing convenience. SimpliSqueeze
features a silicone valve that enables the product to be dispensed with a
slight squeeze of the bottle, and upon release, closes firmly and does not
leak. Consumer awareness of the innovative SimpliSqueeze closure has grown as
a result of its original use in the personal care market. The success of the
SimpliSqueeze technology in the personal care market led to the successful
launch of a non-carbonated sports drink package utilizing this technology.
This new application in the food/beverage market has attracted new customers
to the Company. Most recently, the Company has been awarded several contracts
to supply SimpliSqueeze dispensing closures to bottled water customers.
Another example of a product for which the Company continues to find new
applications is the metered dose aerosol valve. Metered dose aerosol valves
are used to dispense precise amounts of product in very fine particles from
pressurized containers. Traditionally metered dose valves were used to deliver
medication via the pulmonary route. Recently, the Company has begun

                                       4


to work with a bio-technology company who is developing proprietary technology
to orally administer large molecule drugs to be absorbed through the inner
linings of the mouth.

   The Company continues to invest in new dispensing technologies. In 1999,
the Company acquired 80% of Microflow Engineering S.A. ("Microflow"), a
research and development company whose objective is to develop an electronic
dispensing system based on silicone etching technology primarily for the
pharmaceutical market as an alternative to the traditional mechanical pump. In
addition, the Company has internally developed a patented technology for
dispensing fragrance in a lightweight sample blister package as an alternative
to standard vials.

Pumps (62% of 2000 net sales)

   AptarGroup believes it is the leading supplier of pharmaceutical,
fragrance/cosmetic and personal care fine mist pumps worldwide and the second
largest supplier of personal care lotion pumps worldwide. Pumps are finger-
actuated dispensing systems that dispense a spray or lotion from non-
pressurized containers. Pumps are sold to all five of the Company's markets.
Traditional applications for pumps include perfumes, lotions, oral and nasal
sprays, hair sprays and window cleaners. Applications for pumps have recently
expanded to include more viscous products such as spray gels and specialized
skin treatments, as well as an increasing number of food products such as
butter substitutes and candy sprays. The style of pump used depends largely on
the nature of the product being dispensed, from small, fine mist pumps used
with perfume and pharmaceutical products to lotion pumps for more viscous
formulas. In 2000, 1999 and 1998, pump sales accounted for approximately 62%,
61% and 60% respectively, of AptarGroup's net sales.

Fragrance/Cosmetic

   The fragrance/cosmetic market requires a broad range of pump dispensing
systems to meet functional as well as aesthetic requirements. A considerable
amount of research, time and coordination with the customers' development
staff is required to qualify a pump for use with their products. Within the
market, the Company expects the use of pumps to continue to increase,
particularly in the cosmetic sector. For example, packaging for certain
products such as skin moisturizers and anti-aging lotions is undergoing a
conversion to pump systems, which may provide growth opportunities for the
Company.

Pharmaceutical

   Pumps sold to the pharmaceutical market deliver medications orally, nasally
or topically. The pharmaceutical market is unique and different from the other
markets the Company serves. Characteristics of this market include (i)
governmental regulatory requirements, (ii) contaminant-controlled
manufacturing environments, and (iii) a significant amount of time and
research from initially working with pharmaceutical companies at the molecule
development stage of a medication through the eventual distribution to the
market. AptarGroup has clean room manufacturing facilities in France, Germany,
Switzerland, China and the United States. The Company believes that the
conversion from traditional medication forms such as pills and syringes to the
use of pumps for the dispensing of medication will continue to increase.
Potential opportunities for conversion from pills and syringes to pump
dispensing systems include vaccines, cold and flu treatments and hormone
replacement therapies.

Personal Care

   Personal care pumps include both fine mist spray as well as lotion pumps.
Sales of fine mist pumps, for use in hair care, sun care and deodorant
products, have increased significantly over the last several years. The
Company also supplies lotion pumps to the personal care market for products
such as skin moisturizers and soap.

                                       5


Food/Beverage

   Historically, sales of the Company's pumps to this market have not been
significant. However, the Company has recently increased its sales to this
market with applications such as butter substitute sprays, candy sprays and
condiments. The Company believes there will be additional applications for
pumps in this market in the future.

Closures (22% of 2000 net sales)

   The Company believes that it is the largest supplier of dispensing closures
in the United States, and the second largest supplier in Europe. The Company
manufactures primarily dispensing closures and to a small degree, some plastic
non-dispensing closures. Dispensing closures are plastic caps, primarily for
plastic containers, which allow a product to be dispensed without removing the
cap. Closure sales accounted for approximately 22% of AptarGroup's net sales
in 2000, 1999 and 1998.

   Sales of dispensing closures have grown as consumers worldwide have
demonstrated a preference for a package utilizing the convenience of a
dispensing closure. At the same time, consumer marketers are trying to
differentiate their products by incorporating performance enhancing features
such as no-drip dispensing, inverted packaging and directional flow to make
them simpler to use, cleaner and more appealing to consumers.

Personal Care

   Historically, the majority of the dispensing closure sales have been to the
personal care market. Products with dispensing closures include shampoos,
shower gels, conditioners and toothpaste. While many personal care products
have already converted from non-dispensing to dispensing closures, the Company
expects to benefit from its SimpliSqueeze technology as companies utilize more
inverted packaging.

Household

   While the Company has had success worldwide in selling dispensing closures
to this market, it has not represented a significant amount of total
dispensing closure sales. Products utilizing dispensing closures include
dishwashing detergents, laundry care products and household cleaners. The
Company believes this market offers an opportunity for expansion as a result
of conversion from non-dispensing to dispensing closures.

Food/Beverage

   Similar to the household market, sales of dispensing closures to the
food/beverage market has not represented a significant amount of total
dispensing closure sales. However, the Company has recently experienced an
increase in the amount of interest from food marketers who are considering
utilizing dispensing closures for their products. Examples of food/beverage
products currently utilizing dispensing closures include salad dressings,
syrups, condiments, honey, non-carbonated sports drinks and edible oils. The
Company has secured orders to sell SimpliSqueeze closures on single-serve
bottled water applications for delivery in 2001. The Company believes there
are tremendous growth opportunities in the food/beverage market due to the
size of the non-carbonated single-serve beverage market worldwide and
additional conversion from traditional non-dispensing food packages to
dispensing closure systems.

Aerosol Valves (14% of 2000 net sales)

   AptarGroup believes it is the largest aerosol valve supplier in North
America. Aerosol valves dispense product from pressurized containers. The
majority of the aerosol valves sold by the Company are continuous spray valves
with the balance being metered dose valves. Demand for aerosol valves is
dependent upon the consumers' preference for application, consumer perception
of environmental impact, and changes in demand for the products in this
market. Aerosol valve sales accounted for approximately 14%, 15% and 16% of
AptarGroup's net sales in 2000, 1999 and 1998, respectively.

                                       6


   In addition to aerosol valves, the Company has invested in manufacturing
capabilities to produce accessories that are complementary to the valve, such
as customized spray through overcaps. These overcaps provide a higher degree
of differentiation and convenience since the cap does not need to be removed
prior to usage.

Personal Care

   The primary applications in the personal care market are continuous spray
valves for hair care products, deodorants and shaving creams. In addition, the
metered dose valve is used in this market for breath sprays.

Household

   The primary applications for continuous spray valves in the household
market include disinfectants, spray paints, insecticides and automotive
products. Metered dose aerosol valves are used for air fresheners.

Pharmaceutical

   Metered dose aerosol valves are used for dispensing precise amounts of
medication. Aerosol technology allows medication to be broken up into very
fine particles, which enables the drug to be delivered via the pulmonary
system. The Company works with pharmaceutical companies as they work to phase
out the use of aerosol chlorofluorocarbon ("CFC") propellants. The Company
expects to increase its market share of metered dose valves to this market as
pharmaceutical companies replace CFC products with alternative propellants.

Research and Development

   The Company is committed to developing innovative products and adapting
existing products for new markets and customer requirements. Expenditures for
research and development activities were $26.9 million, $25.6 million
(excluding a $3.3 million write-off of purchased in-process research and
development associated with the Microflow acquisition), and $23.6 million in
2000, 1999 and 1998, respectively. These costs were associated with a number
of products in varying stages of development.

Patents and Trademarks

   AptarGroup will continue to sell its products under the names used by its
operating units and is not currently offering any products under the
AptarGroup name. The names used by its operating units have been trademarked.

   AptarGroup customarily seeks patent and trademark protection for its
products and currently owns and has numerous applications pending for United
States and foreign patents and trademarks. In addition, certain of
AptarGroup's products are produced under patent licenses granted by third
parties. The majority of AptarGroup's net sales are generated by products
which have patent protection on either the product or a component of the
product. Management believes that it possesses certain technical capabilities
in making its products that would also make it difficult for a competitor to
duplicate them.

Technology

   Pumps and aerosol valves require the assembly of up to 15 different
plastic, metal and rubber components using high-speed equipment. When molding
dispensing closures, or plastic components to be used in pump or aerosol valve
products, the Company uses advanced plastic injection molding technology,
including large cavitation plastic injection molds. These molds are required
to maintain tolerances as small as one thousandth of an inch and manufacture
products in a high-speed, cost-effective manner. The Company has experience in
liquid silicone rubber molding that the Company utilizes in its dispensing
closure operations. The Company also uses bi-injection molding technology in
its various product lines to develop new innovative products for the packaging
industry. The Microflow acquisition provides electronic capabilities that the
Company did not previously possess.

                                       7


Manufacturing and Sourcing

   The principal raw materials used in AptarGroup's production are plastic
resins and certain metal products. AptarGroup believes an adequate supply of
such raw materials is readily available from existing and alternative sources.
The Company attempts to offset cost increases through improving productivity
and increasing selling prices over time, as allowed by market conditions.
AptarGroup also purchases plastic and metal components that are used in the
final assembly of its products from suppliers near its production facilities.
Certain suppliers of these components have unique technical abilities that
make AptarGroup dependent on them, particularly for aerosol valve and pump
production in North America. In addition, the Company's pharmaceutical
products often use specific approved plastic resin for its customers.
Significant delays in receiving components from these suppliers or
discontinuance of an approved plastic resin would require AptarGroup to seek
alternative sources, which could result in higher costs as well as impact the
ability of the Company to supply products in the short term. The Company has
not experienced such delays.

Sales and Distribution

   Sales of products are primarily through AptarGroup's own sales force. To a
limited extent, AptarGroup also uses the services of independent
representatives and distributors who sell AptarGroup's products as independent
contractors to certain smaller customers and export markets. Backlogs are not
a significant factor. Most orders placed with the Company are ready for
delivery within 120 days. Some customers place blanket orders, which extend
beyond this delivery period. However, deliveries against these orders are
subject to change.

Customers

   The demand for AptarGroup's products is influenced by the demand for the
products of AptarGroup's customers. Demand for the products of AptarGroup's
customers may be affected by general economic conditions, government
regulations, tariffs and other trade barriers. AptarGroup's customers include
many of the largest personal care, fragrance/cosmetic, pharmaceutical,
household products and food/beverage marketers in the world. The Company has
over 2,500 customers with no single customer accounting for greater than 6% of
2000 net sales. Over the past few years, a consolidation of the Company's
customer base has occurred. This trend is expected to continue. A
concentration of customers may result in pricing pressures or a loss of
volume. This situation also presents opportunities for increasing sales due to
the breadth of the Company's product line, its international presence, and
long-term relationships with certain customers.

International Business

   A significant number of AptarGroup's operations are located outside the
United States. Sales in Europe for the years ended December 31, 2000, 1999 and
1998 were approximately 53%, 54% and 57%, respectively, of net sales. The
majority of units sold in Europe are manufactured at facilities in England,
France, Germany, Ireland, Italy, Spain and Switzerland. Other geographic areas
serviced by AptarGroup include Argentina, Australia, Brazil, Canada, Czech
Republic, China, India, Indonesia, Japan and Mexico, though the combined sales
from these areas is not significant to AptarGroup's consolidated sales. Export
sales from the United States were $44.3 million, $57.9 million and $21.4
million in 2000, 1999 and 1998, respectively.

Foreign Currency

   A significant number of AptarGroup's operations are located outside of the
United States. Because of this, movements in exchange rates may have a
significant impact on the translation of financial conditions and results of
operations of AptarGroup's foreign entities. The Company's primary foreign
exchange exposure is to the Euro, but the Company has foreign exchange
exposure to South American and Asian currencies as well as the British Pound.
The Company manages its exposures to foreign exchange principally with forward
exchange contracts to hedge certain firm purchase and sales commitments and
intercompany cash transactions denominated in foreign currencies. A
strengthening U.S. dollar relative to foreign currencies has a dilutive
translation effect

                                       8


on the Company's financial condition and results of operations. Conversely, a
weakening U.S. dollar has an additive effect.

   In some cases, the Company sells products denominated in a currency
different from the currency in which the related costs are incurred. Changes
in exchange rates on such inter-country sales could materially impact the
Company's results of operations.

Working Capital Practices

   Collection and payment periods tend to be longer for the Company's
operations located outside the United States due to local business practices.
Historically, the Company has not needed to keep significant amounts of
finished goods inventory to meet customer requirements.

Employee and Labor Relations

   AptarGroup has approximately 6,400 full-time employees. Of the full-time
employees, approximately 1,700 are located in North America, 4,200 are located
in Europe and the remaining 500 are located in Asia and South America.
Approximately 200 of the North American employees are covered by a collective
bargaining agreement, while the majority of the Company's international
employees are covered by collective bargaining arrangements made at either the
local or national government level in their respective countries. Termination
of employees at certain AptarGroup European operations could be costly due to
local regulations regarding severance benefits. Management of AptarGroup
considers its employee relations to be good.

Competition

   All of the markets in which AptarGroup operates are highly competitive and
the Company continues to experience price competition in all product lines and
markets. Competitors include privately and publicly held entities.
AptarGroup's competitors range from regional to international companies.
AptarGroup expects the market for its products to remain competitive.

   AptarGroup believes its competitive advantages are consistent high levels
of innovation, quality, service and geographic diversity and breadth of
products. The Company's manufacturing strength lies in the ability to mold
complex plastic components in a cost-effective manner and to assemble products
at high speeds.

Environment

   AptarGroup's manufacturing operations primarily involve plastic injection
molding and automated assembly processes, and to a limited degree metal
annodization. Historically, the environmental impact of these processes has
been minimal, and management believes it meets current environmental standards
in all material respects.

Government Regulation

   To date, the manufacturing operations of AptarGroup have not been
significantly affected by environmental laws and regulations relating to the
environment.

   Certain AptarGroup products are affected by government regulation. Growth
of packaging using aerosol valves has been restrained by concerns relating to
the release of certain chemicals into the atmosphere. Both aerosol and pump
packaging are affected by government regulations regarding the release of
VOC's (volatile organic compounds) into the atmosphere. Certain states within
the United States have regulations that required the reduction in the amount
of VOC's that can be released into the atmosphere and the potential exists for
this type of regulation to expand to a worldwide basis. These regulations
required the Company's customers to reformulate certain aerosol and pump
products, which may have affected the demand for such products. The Company
owns patents and has developed systems to function with alternative propellant
and product formulations.

                                       9


   Aerosol packaging of paints has also been adversely impacted by local
regulations adopted in many large cities in the United States designed to
address the problem of spray painted graffiti. Aerosol packaging may also be
adversely impacted by insurance cost considerations relating to the storage of
aerosol products.

   Government regulation in the dispensing closure product line primarily
relates to waste reduction. The Company's dispensing closures are plastic and
mainly consist of polypropylene, a recyclable plastic. The Company also uses
recycled plastic in its manufacturing process.

   Future government regulations could include medical cost containment
policies. For example, reviews by various governments to determine the number
of drugs or prices thereof that will be paid by their insurance systems could
affect future sales to the pharmaceutical industry. Such regulation could
adversely affect prices of and demand for the Company's pharmaceutical
products. The Company believes that the focus on the cost effectiveness of the
use of medications as compared to surgery and hospitalization provides an
opportunity for the Company to expand sales to the pharmaceutical market.
Regulatory requirements impact the Company's customers and could affect the
Company's investment in and manufacturing of products for the pharmaceutical
market.

Item 2. Properties

   The principal offices and manufacturing facilities of AptarGroup are either
owned or leased by the Company or its subsidiaries. None of the owned
principal properties is subject to a lien or other encumbrance material to the
operations of the Company. The Company believes that existing operating leases
will be renegotiated as they expire or that suitable alternative properties
can be leased on acceptable terms. The Company considers the condition and
extent of utilization of its manufacturing facilities and other properties to
be generally good, and the capacity of its plants to be adequate for the needs
of its business.

   The locations of the Company's principal manufacturing facilities, by
country, are set forth below:

   In addition to the above countries, the Company has sales offices or other
manufacturing facilities in Australia, Canada, India, Indonesia, Japan and
Spain. The Company's corporate office is located in Crystal Lake, Illinois.

Item 3. Legal Proceedings

   Legal proceedings involving the Company generally relate to product
liability and patent infringement issues. In the opinion of AptarGroup's
management, the outcome of pending claims and litigation is not likely to have
a material adverse effect on the Company's financial position or the results
of its operations.

   Historically, product liability claims for all products of the Company have
been minimal. However, the increase in pump and aerosol valve applications for
pharmaceutical products may increase the risk associated with product
liability claims. Quality control systems are specifically designed to prevent
defects in the Company's products. Additionally, the Company maintains product
liability insurance in excess of its historical claims experience.
