                   ENFORCEABILITY OF CERTAIN CIVIL LIABILITIES

     We are incorporated under the laws of The Netherlands and a substantial
portion of our assets are located outside the United States. In addition,
members of our Managing and Supervisory Boards, our officers and certain experts
named herein reside outside the United States. As a result, it may be difficult
for investors to effect service of process within the United States upon us or
such other persons, or to enforce outside the United States judgments obtained
against such persons in U.S courts, in any action, including actions predicated
upon the civil liability provisions of U.S. securities laws. In addition, it may
be difficult for investors to enforce, in original actions brought in courts in
jurisdictions located outside the United States, rights predicated upon the U.S.
securities laws.

     We have been advised by legal counsel in The Netherlands, De Brauw
Blackstone Westbroek N.V., that the United States and The Netherlands do not
currently have a treaty providing for reciprocal recognition and enforcement of
judgments (other than arbitration awards) in civil and commercial matters.
Therefore, a final judgment for the payment of money rendered by any federal or
state court in the United States based on civil liability, whether or not
predicated solely upon the federal securities laws, would not be directly
enforceable in The Netherlands. However, if the party in whose favor such final
judgment is rendered brings a new suit in a competent court in The Netherlands,
such party may submit to the Dutch court the final judgment which has been
rendered in the United States. If the Dutch court finds that the jurisdiction of
the federal or state court in the United States has been based on grounds which
are internationally acceptable and that proper legal procedures have been
observed, the Dutch court will, in principle, give binding effect to the final
judgment which has been rendered in the United States unless such judgment
contravenes Dutch principles of public policy. Based on the foregoing, there can
be no assurance that U.S. investors will be able to enforce against us, members
of our Managing or Supervisory Boards, officers or certain experts named herein
who are residents of The Netherlands or countries other than the United States
any judgments obtained in U.S. courts in civil and commercial matters, including
judgments under the federal securities laws. In addition, there is doubt as to
whether a Dutch court would impose civil liability on such persons in an
original action predicated solely upon the federal securities laws of the United
States brought in a competent court in The Netherlands against us or such
members, officers or experts, respectively. See "Risk Factors--Enforcement of
Judgments".

                               PROSPECTUS SUMMARY

     This summary highlights information incorporated by reference or contained
elsewhere in this prospectus. It is not complete and may not contain all of the
information that you should consider before investing in our securities. You
should read the entire prospectus and the documents incorporated by reference
herein carefully, including the "Risk Factors" section contained herein and the
more detailed financial statements, and notes to financial statements,
incorporated by reference in this prospectus.


                                   The Company

     We were incorporated on April 29, 1996 as a public limited liability
company ("naamloze vennnootschap") under Dutch law as a holding company for our
wholly owned subsidiaries, and have our legal seat in Venlo, The Netherlands. As
a holding company, we conduct our business through our wholly-owned
subsidiaries:

        .  QIAGEN GmbH (Germany),
        .  QIAGEN Ltd. (England),
        .  QIAGEN AG (Switzerland),
        .  QIAGEN S.A. (France),
        .  QIAGEN Pty. Ltd. (Australia),
        .  QIAGEN Inc. (Canada),
        .  QIAGEN K.K. (Japan)
        .  QIAGEN S.p.A. (Italy),
        .  QIAGEN Instruments AG, formerly Rosys Instruments AG (Switzerland),
        .  QIAGEN Operon GmbH (Germany),
        .  Sawady Technologies Co., Ltd. (Japan), and
        .  QIAGEN North American Holdings, Inc. (United States).

     QIAGEN North American Holdings, Inc. wholly owns our other U.S.
subsidiaries: QIAGEN, Inc., QIAGEN Sciences, Inc. QIAGEN Genomics, Inc. and
QIAGEN Operon, Inc. (United States). In addition, we own 50% of PreAnalytiX GmbH
(Germany) and 55% of Accord Co., Ltd. (Japan).

     We believe, based on the nature of our products and technologies and on our
United States and European market shares as supported by independent market
studies, that we are the world's leading provider of innovative enabling
technologies and products for the separation and purification of nucleic acids.
Since 1986, we have developed and marketed a broad range of proprietary products
for the academic and industrial research market. The increased understanding of
nucleic acid structure and function combined with the development of
technologies such as Polymerase Chain Reaction (PCR) have resulted in a rapid
expansion in the potential uses of nucleic acids beyond the research market into
developing commercial markets. These include (1) genomics, (2) nucleic
acid-based molecular diagnostics, and (3) genetic vaccination and gene therapy.
We believe that by targeting our enabling nucleic acid separation and
purification technologies to numerous participants in each of these developing
commercial markets, we will optimize and diversify our opportunities for growth.

     Our objective is to expand our leadership position by employing the
following strategies: (1) to expand our leadership in the research market and to
leverage such leadership to diversify its opportunities for future growth into
an array of developing commercial markets, (2) to maintain and further expand
technology leadership by investing significant resources in research and
development and through strategic acquisitions, (3) to provide a comprehensive
portfolio of products for specific nucleic acid handling, separation and
purification applications, (4) to accelerate consumable sales through new
automation product lines, and (5) to emphasize customer contacts and service.

     On April 17, 2002, we completed the acquisition of Xeragon, Inc. of
Huntsville, Alabama, pursuant to an agreement and plan of merger with Xeragon
dated as of March 28, 2002. In connection with this acquisition, we issued
564,334 of our common shares to the shareholders of Xeragon in exchange for all
of the outstanding capital stock of Xeragon. We structured this acquisition to
qualify as a tax-free reorganization. Established in 2001,

                                       4



Xeragon is a market and technology leader for products and services focusing on
synthetic nucleic acids, particularly siRNA. Since synthetic nucleic acids are
used in the analysis of nucleic acids purified from natural sources, we believe
that Xeragon's products will be highly synergistic with our own and will enable
us to extend significantly our presence into the genomics and genetic analysis
markets.

     On May 28, 2002, we announced that we had entered into an agreement to
acquire GenoVision AS, a Norwegian company focused on the development of
reagents and solutions for certain nucleic acid diagnostic markets, such as the
HLA market. We completed this acquisition on June 14, 2002. Subject to the terms
of the agreement, we paid approximately $14 million in cash and issued
approximately 940,000 shares of our common stock in exchange for all of the
outstanding stock of GenoVision. In addition, we agreed to pay a success fee of
up to $3 million based on GenoVision's performance in the twelve months
following the acquisition. We believe that this acquisition will provide us with
unique, automated solutions for the purification of nucleic acids based on
GenoVisions' proprietary magnetic particle technology. Genovision has two wholly
owned subsidiaries: GenoVision VertriebsgesmbH, Austria, and Genovision Inc,
USA. In addition, the company owns a 60% share in Particle Solutions AS, Norway.

     Our principal executive offices are located at Spoorstraat 50, 5911 KJ
Venlo, The Netherlands, telephone number +31-77-320-8400. We are registered with
the trade registry in Venlo, The Netherlands, under no. 12036979. The offices of
QIAGEN GmbH, our principal operating subsidiary, are located at
Max-Volmer-Strasse 4, D-40724 Hilden, Germany, telephone number +49-2103-29-0.
Parties within the United States may also contact QIAGEN, Inc. in Valencia,
California at 800-426-8157 to obtain information.


                                  RISK FACTORS

     In addition to the other information in this prospectus, prospective
purchasers of the common shares offered hereby should consider carefully the
following risk factors in evaluating us and our business. This prospectus and
the documents incorporated herein by reference contain forward-looking
statements within the meaning of the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995. These statements can be identified by
the use of forward-looking terminology such as "may," "will," "could," "expect,"
"anticipate," "estimate," "continue" or other similar words. Reference is made
in particular to the description of our plans and objectives for future
operations, assumptions underlying such plans and objectives, and other
forward-looking statements included in the sections entitled "Prospectus
Summary", and in "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and "Business" incorporated by reference in this
prospectus. Such statements are based on management's current expectations and
are subject to a number of factors and uncertainties which could cause actual
results to differ materially from those described in the forward-looking
statements. Factors which could cause such results to differ materially from
those described in the forward-looking statements include those set forth in the
risk factors below. When considering forward-looking statements, you should keep
in mind that the risk factors could cause our actual results to differ
significantly from those contained in any forward-looking statement.

An inability to manage our growth or the expansion of our operations could
adversely affect our business

     Our business has grown rapidly, with total net revenues increasing from
$75.4 million in 1997 to $263.8 million in 2001. We have recently opened our new
research and manufacturing facility in Germantown, Maryland, upgraded our
operating and financial systems and expanded the geographic area of our
operations, resulting in substantial growth in the number of our employees, as
well as increased responsibility for both existing and new management personnel.
The rapid expansion of our business and growth in personnel may place a strain
on our management and operational systems. Our future operating results will
depend on the ability of our management to continue to implement and improve our
research, product development, sales and marketing and customer support
programs, enhance our operational and financial control systems, expand, train
and manage our employee base, and effectively address new issues related to our
growth as they arise. There can be no assurance that we will be able to manage
our recent or any future expansion successfully, and any inability to do so
could have a material adverse effect on our results of operations.

                                       5



We may have difficulty integrating acquisitions of technologies and businesses

     During the past several years we have consummated a number of acquisitions
of companies, through which we have gained access to technologies and products
that complement our internally developed product lines. In the future, we may
acquire additional technologies, products or businesses to expand our existing
and planned business. We may not be able to achieve the benefits expected from
any potential acquisition in a reasonable time frame, or at all. Acquisitions
would expose us to the risks associated with the:

     .  assimilation of new technologies, operations, sites and personnel;

     .  diversion of resources from our existing business and technologies;

     .  inability to generate revenues to offset associated acquisition costs;

     .  inability to maintain uniform standards, controls, and procedures;

     .  inability to maintain relationships with employees and customers as a
        result of any integration of new management personnel;

     .  issuance of dilutive equity securities;

     .  incurrence or assumption of debt; or

     .  additional expenses associated with future amortization or impairment of
        acquired intangible assets or potential businesses.

Our failure to address these risks successfully could have a material adverse
effect on our business.

Our operating results may vary significantly

     Our operating results may vary significantly from quarter to quarter and
from year to year, depending on factors such as the level and timing of our
customers' research and commercialization efforts, timing of our customers'
funding, the timing of our research and development and sales and marketing
expenses, the introduction of new products by us or our competitors, competitive
conditions, exchange rate fluctuations and general economic conditions. Our
expense levels are based in part on our expectations as to future revenues.
Consequently, revenues or profits may vary significantly from quarter to quarter
or from year to year, and revenues and profits in any interim period will not
necessarily be indicative of results in subsequent periods.

Our common shares may have a volatile public trading price

     The market price of the common shares since our initial public offering in
June 1996 has increased significantly and been highly volatile. In addition to
overall stock market fluctuations, factors which may have a significant impact
on the market price of the common shares include:

     .  announcements of technological innovations or the introduction of new
        products by us or our competitors;

     .  developments in our relationships with collaborative partners;

     .  quarterly variations in our operating results;

     .  changes in government regulations or patent laws;

                                       6



     .  developments in patent or other proprietary rights;

     .  and general market conditions relating to the pharmaceutical and
        biotechnology industries.

The stock market has from time to time experienced extreme price and trading
volume fluctuations that have particularly affected the market for
technology-based companies and that have not necessarily been related to the
operating performance of such companies. These broad market fluctuations may
adversely affect the market price of our common shares.

Exchange rate fluctuations may adversely affect our business

     Since we currently market our products in over 42 countries throughout the
world, a significant portion of our business is conducted in currencies other
than the U.S. dollar, our reporting currency. As a result, fluctuations in value
relative to the U.S. dollar of the currencies in which we conduct our business
have caused and will continue to cause foreign currency transaction gains and
losses. Foreign currency transaction gains and losses arising from normal
business operations are charged against earnings in the period incurred. Due to
the number of currencies involved, the variability of currency exposures and the
potential volatility of currency exchange rates, we cannot predict the effects
of exchange rate fluctuations upon future operating results. While we engage in
foreign exchange hedging transactions to manage our foreign currency exposure,
there can be no assurance that our hedging strategy will adequately protect our
operating results from the effects of future exchange rate fluctuations.

We heavily rely on air cargo carriers and other overnight logistics services

     The Company's customers within the scientific research markets typically do
not keep a significant inventory of QIAGEN products and consequently require
overnight delivery of purchases. As such, the Company heavily relies on air
cargo carriers such as FedEx and UPS. If overnight services are suspended or
delayed and other delivery carriers cannot provide satisfactory services,
customers may suspend a significant amount of work requiring nucleic acid
purification. If there are no adequate delivery alternatives available, sales
levels could be negatively affected.

Our continued growth is dependent on the development and success of new products

     Our continued growth is dependent on new product introductions that are
well received in the market. We focus our product development efforts on
expanding our existing products and developing innovative new products in
selected areas where we have expertise and have identified substantial unmet
market needs. There can be no assurance that we will be able to introduce new
products or that new product releases will be successfully launched and received
by our customers.

Competitors may render some or all of our products or future products
noncompetitive

     Our primary competition stems from traditional separation and purification
methods that utilize widely available reagents and other chemicals. The success
of our business depends in part on the continued conversion of current users of
such traditional methods to our nucleic acid-based separation and purification
technologies and products. There can be no assurance, however, as to how quickly
such conversion will occur. We also experience, and expect to continue to
experience, increasing competition in various segments of our nucleic acid-based
separation business from companies providing nucleic acid-based separation
products in kit form. Certain of such competitors have substantially greater
financial, research and development, sales and marketing and personnel resources
than we do and may have significantly more experience in developing,
manufacturing, marketing and supporting new products. There can be no assurance
that such companies will not develop products that are directly competitive with
our current or planned products or that they will not be able to penetrate
markets more rapidly than we can. To the extent that our sales depend on future
sales of diagnostic or therapeutic products by our customers, we may also be
adversely affected by the intense competition in the pharmaceutical and
biotechnology industries. If QIAGEN is not able to maintain its technological
advantage over competing products, to expand its market presence, to preserve
customer loyalty and thus to compete effectively against its existing or future
competitors, QIAGEN's financial condition and results of operations could be
materially adversely affected.

                                       7



Rapid technological change may render some or all of our technologies and
products obsolete

     Extensive research and technological change characterize our business
environment, and new developments are expected to continue at a rapid pace.
There can be no assurance that developments by others will not render our
technologies and products uneconomical or obsolete.

We depend on patents and proprietary rights that may fail to protect our
business

     Our success will depend to a large extent on our ability to develop
proprietary products and technologies and to establish and protect our patent
and trademark rights with respect thereto. We currently own 32 issued patents in
the United States, 27 issued patents in Germany and 166 issued patents in other
major industrialized countries. In addition, we have approximately 235 pending
patent applications and we intend to file applications for additional patents as
our products and technologies are developed. However, the patent positions of
technology-based companies, including QIAGEN, involve complex legal and factual
questions and may be uncertain, and the laws governing the scope of patent
coverage and the periods of enforceability of patent protection are continuing
to evolve. In addition, patent applications in the United States are maintained
in secrecy until patents issue, and publication of discoveries in the scientific
or patent literature tend to lag behind actual discoveries by several months.
Therefore, no assurance can be given that patents will issue from any patent
applications owned by or licensed to us or, if patents do issue, that the claims
allowed will be sufficiently broad to protect our technology. In addition, no
assurance can be given that any issued patents owned by or licensed to us will
not be challenged, invalidated or circumvented, or that the rights granted
thereunder will provide competitive advantages to us.

     The biotechnology industry has been characterized by extensive litigation
regarding patents and other intellectual property rights. We are aware that
patents have been applied for and/or issued to third parties claiming
technologies for the separation and purification of nucleic acids that are
closely related to those used by us. From time to time we receive inquiries
requesting confirmation that we do not infringe patents of third parties. We
endeavor to follow developments in this field, and we do not believe that our
technologies and/or products infringe any proprietary rights of third parties.
However, there can be no assurance that third parties will not challenge our
activities and, if so challenged, that we will prevail. In addition, the patent
and proprietary rights of others could require us to alter our products or
processes, pay licensing fees or cease certain activities, and there can be no
assurance that we will be able to license any technologies that we may require
on acceptable terms. In addition, litigation, including proceedings that may be
declared by the U.S. Patent and Trademark Office or the International Trade
Commission, may be necessary for us to respond to any assertions of
infringement, enforce our patent rights and/or determine the scope and validity
of our proprietary rights or those of third parties. Litigation could involve
substantial cost to us, and there can be no assurance that we would prevail in
any such proceedings.

     Certain of our products incorporate patents and technologies that are
licensed from third parties. These licenses impose various commercialization,
sublicensing and other obligations on us. Our failure to comply with these
requirements could result in the conversion of the applicable license from being
exclusive to non-exclusive in nature or, in some cases, termination of the
license.

     We also rely on trade secrets and proprietary know-how, which we seek to
protect through confidentiality agreements with our employees and consultants.
There also can be no assurance that any confidentiality agreements between us
and our employees, consultants, outside scientific collaborators and sponsored
researchers and other advisors will provide meaningful protection for our trade
secrets or adequate remedies in the event of unauthorized use or disclosure of
such information. There also can be no assurance that our trade secrets will not
otherwise become known or be independently developed by competitors.

     We currently engage in, and from time to time may engage in, collaborations
with academic researchers and institutions. There can be no assurance that under
the terms of such collaborations, third parties will not acquire rights in
certain inventions developed during the course of the performance of such
collaborations.

                                       8



We rely on collaborative commercial relationships to develop some of our
products

     Our long-term business strategy includes entering into strategic alliances
or marketing and distribution arrangements with corporate partners relating to
the development, commercialization, marketing and distribution of certain of our
existing and potential products. There can be no assurance that we will be able
to negotiate such collaborative arrangements on acceptable terms, or that any
such relationships will be scientifically or commercially successful. In
addition, there can be no assurance that we will be able to maintain such
relationships or that our collaborative partners will not pursue or develop
competing products or technologies, either on their own or in collaboration with
others.

Our ability accurately to forecast our results during each quarter is impacted
by the fact that a substantial percentage of our sales are booked in the final
weeks or days of the quarter.

     The markets we serve are characterized by a high percentage of purchase
orders being received in the final few weeks or even days of each quarter.
Although this varies from quarter to quarter, increasingly our customers
generally make a large portion of their purchase decisions late in each fiscal
quarter, as both their budgets and requirements for the coming quarter become
clearer. As a result, even late in each fiscal quarter, we cannot predict with
any certainty whether our revenue forecasts for the quarter will be achieved.
Historically, we have been able to rely on the overall pattern of customer
purchase orders during prior periods to project with reasonable accuracy our
anticipated sales for the current or coming quarters. However, if our customers'
purchases during a quarter vary from historical patterns, our final quarterly
results could deviate significantly from our projections. Consequently, our
revenue forecasts for any given quarter may prove not to have been accurate.
Because of the end-of-quarter buying patterns of our customers, we may not have
enough information to confirm or revise our sales projections during the
quarter. If we fail to achieve our forecasted revenues for a particular quarter,
our stock price could be adversely affected.

                                       9



We have risks relating to doing business internationally

     Our business involves operations in several countries. Our current
consumable and BioRobot production and manufacturing facilities are located in
Germany, our instrumentation facility is located in Switzerland, and we have
added, through the acquisition of the Sawady group of companies in Tokyo, and
establishment of QIAGEN Operon GmbH in Cologne, our synthetic DNA production
businesses in Japan and Germany. We expect to begin production of certain of our
consumable products at our new facility in Germantown, Maryland in the second
quarter of 2002. We also operate U.S. facilities in Alameda, California
(synthetic DNA production), Valencia, California (sales and distribution), and
Bothell, Washington (single nucleotide polymorphism (SNP) analyses). We also
have established sales subsidiaries in Japan, the United Kingdom, France,
Switzerland, Australia, Canada and Italy. In addition, our products are sold
through independent distributors serving more than 42 other countries.

     Conducting and launching operations on an international scale requires
close coordination of activities across multiple jurisdictions and time zones
and consumes significant management resources. We have invested heavily in
computerized information systems in order to manage more efficiently the widely
dispersed components of our operations. In the past year, we have expanded our
SAP business information system that integrates our North American and European
subsidiaries.

     Our operations are also subject to other risks inherent in international
business activities, such as general economic conditions in the countries in
which we operate, overlap of different tax structures, unexpected changes in
regulatory requirements, compliance with a variety of foreign laws and
regulations, and longer accounts receivable payment cycles in certain countries.
Other risks associated with international operations include import and export
licensing requirements, trade restrictions, exchange controls and changes in
tariff and freight rates. As a result of the above conditions, an inability to
successfully manage our international operations could have a material adverse
impact on our operations.

Our success depends on the continued employment of our key personnel, any of
whom we may lose at any time

     Our success depends, to a significant extent, on key members of our
management and scientific staff. The loss of such employees could have a
material adverse effect on us. Our ability to recruit and retain qualified
skilled personnel to perform future research and development work will also be
critical to our success. Due to the intense competition for experienced
scientists from numerous pharmaceutical and biotechnology companies and academic
and other research institutions, there can be no assurance that we will be able
to attract and retain such personnel on acceptable terms. Our planned activities
will also require additional personnel, including management, with expertise in
areas such as manufacturing and marketing, and the development of such expertise
by existing management personnel. The inability to recruit such personnel or
develop such expertise could have a material adverse impact on our operations.

Our business may require substantial additional capital, which we may not be
able to obtain on commercially reasonable terms, if at all

     Our future capital requirements and level of expenses will depend upon
numerous factors, including the costs associated with:

     .  our marketing, sales and customer support efforts;

     .  our research and development activities;

     .  the expansion of our facilities;

     .  the consummation of possible future acquisitions of technologies,
        products or businesses;

     .  the demand for our products and services; and

                                       10



     .  the refinancing of debt.

     In addition, we have outstanding loan facilities at March 31, 2002 of
approximately $70.0 million, of which approximately $61.2 million will become
due in May 2003. To the extent that our existing resources are insufficient to
fund our activities, we may need to raise funds through public or private
financings of debt or equity securities. No assurance can be given that such
additional financings will be available or, if available, can be obtained on
terms acceptable to us. If adequate funds are not available, we may have to
reduce expenditures for research and development, production or marketing, which
could have a material adverse effect on our business. To the extent that
additional capital is raised through the sale of equity, the issuance of such
securities could result in dilution to our shareholders.

Changing government regulations may adversely impact our business

     QIAGEN and our customers operate in a highly regulated environment
characterized by continuous changes in the governing regulatory framework.
Genetic research activities as well as products commonly referred to as
"genetically engineered" - such as certain food and therapeutic products - are
subject to governmental regulation in most developed countries, especially in
the major markets for pharmaceutical and diagnostic products (i.e., the European
Union, the United States, and Japan). In the recent past, several highly
publicized scientific successes (most notably in the areas of genomic research
and "cloning") have stirred a public debate in which ethical, philosophical and
religious arguments have been raised against an unlimited expansion of genetic
research and the use of products developed thereby. As a result of this debate,
some key countries might increase the existing regulatory barriers; this, in
turn, could adversely affect the demand for our products and prevent us from
fulfilling our growth expectations. Furthermore, there can be no assurance that
any future changes of applicable regulations will not require further
expenditures or an alteration, suspension or liquidation of our operations in
certain areas, or even in their entirety.

Additionally, we are subject to various laws and regulations generally
applicable to businesses in the different jurisdictions in which we operate,
including laws and regulations applicable to the handling and disposal of
hazardous substances. We do not expect compliance with such laws to have a
material effect on our capital expenditures, earnings or competitive position.
Although we believe that our procedures for handling and disposing of hazardous
materials comply with the standards prescribed by applicable regulations, the
risk of accidental contamination or injury from these materials cannot be
completely eliminated. In the event of such an accident, we could be held liable
for any damages that result, and any such liability could have a material
adverse effect on us.

     Sales volumes of certain of our products in development may be dependent on
commercial sales by our customers of diagnostic and pharmaceutical products,
which will require pre-clinical studies and clinical trials. Such trials will be
subject to extensive regulation by governmental authorities in the United States
and other countries and could impact customer demand for our products.

Risk of price controls is a threat to our profitability

     The ability of many of our customers to successfully market their products
depends in part on the extent to which reimbursement for the costs of these
products is available from governmental health administrations, private health
insurers and other organizations. Governmental and other third party payers are
increasingly seeking to contain health care costs and to reduce the price of
medical products and services. Therefore, the biotech industry, the diagnostics
industry and the pharmaceutical industry, as a whole, is exposed to the
potential risk of price controls by these entities. If there are not adequate
reimbursement levels, the commercial success of our customers and, hence, of
QIAGEN itself - could be adversely affected.

Our business exposes us to potential product liability

     The marketing and sale of nucleic acid-based products and services for
certain applications entail a potential risk of product liability, and there can
be no assurance that product liability claims will not be brought against us. We
currently carry product liability insurance coverage, which is limited in scope
and amount, but which

                                       11



we believe is currently appropriate for our purposes. There can be no assurance,
however, that we will be able to maintain such insurance at reasonable cost and
on reasonable terms, or that such insurance will in fact be adequate to protect
us against any or all potential claims or losses.

Provisions of our Articles of Association and Dutch law may inhibit a takeover,
which could limit the price investors might be willing to pay in the future for
our common shares

     Our Articles of Association (the "Articles of Association") and the
applicable laws of The Netherlands contain provisions that may have
anti-takeover effects. Among other things, the Articles of Association provide
that our joint meeting of the Supervisory Board and Managing Board (the "Joint
Meeting") may make binding nominations for the election of directors, which can
only be overridden by shareholders with a two-thirds majority of the votes cast,
which majority must represent more than 50 percent of the outstanding shares;
that preference shares may in certain instances be issued to third parties
selected by us giving such parties preferred dividend rights and placing
additional votes in hands friendly to our Supervisory Board; that significant
transactions such as a merger or sale of substantially all our assets can only
be approved by specified super-majority votes unless such transactions were
proposed to the general meeting by the Supervisory Board; and that the Articles
of Association can only be amended based on a proposal of our Supervisory Board.
Such provisions may have the effect of delaying, deterring or preventing a
change in control that might otherwise be considered to be in the best interest
of shareholders.

Our holding company structure makes us dependent on the operations of our
subsidiaries

     We were incorporated under Dutch law as a public limited liability company
and we are organized as a holding company. Currently, our material assets are
the outstanding shares of our subsidiaries. We, therefore, are dependent upon
payments, dividends and distributions from our subsidiaries for funds to pay our
operating and other expenses and to pay future cash dividends or distributions,
if any, to holders of the common shares. The lending arrangement entered into by
QIAGEN GmbH with a group of banks led by Deutsche Bank in 2001, limits the
amount of distributions that can be made to QIAGEN N.V. during the period the
borrowings are outstanding. Dividends or distributions by subsidiaries to us in
a currency other than the U.S. dollar may result in a loss upon a subsequent
conversion or disposition of such foreign currency, including a subsequent
conversion into U.S. dollars.

We do not anticipate paying dividends on our common shares

     We have not paid cash dividends since our inception and do not anticipate
paying any cash dividends on the common shares for the foreseeable future.
Although we do not anticipate paying any cash dividends, any cash dividends paid
in a currency other than the U.S. dollar will be subject to the risk of foreign
currency transaction losses.

Future sales of our common shares could adversely affect our stock price

     Future sales of substantial amounts of our common shares in the public
market, or the perception that such sales may occur, could adversely affect the
market price of the common shares. As of June 14, 2002, we had outstanding
144,384,622 common shares plus 8,668,700 outstanding stock options, of which
4,678,011 were exercisable at June 14, 2002. A total of 18,968,000 common shares
are reserved for issuance under our stock option plan. All of our outstanding
common shares are freely saleable except 12,250,612 shares held by our
affiliates, which are subject to certain limitations on resale.

United States civil liabilities may not be enforceable against us

     We are incorporated under the laws of The Netherlands and substantial
portions of our assets are located outside the United States. In addition,
certain members of our Managing and Supervisory Boards, our officers and certain
experts named herein reside outside the United States. As a result, it may be
difficult for investors to effect service of process within the United States
upon us or such other persons, or to enforce outside the U.S. judgments obtained
against such persons in U.S. courts, in any action, including actions predicated
upon the civil liability provisions of

                                       12



U.S. securities laws. In addition, it may be difficult for investors to enforce,
in original actions brought in courts in jurisdictions located outside the
United States, rights predicated upon the U.S. securities laws. There is no
treaty between the United States and The Netherlands for the mutual recognition
and enforcement of judgments (other than arbitration awards) in civil and
commercial matters. Therefore, a final judgment for the payment of money
rendered by any federal or state court in the United States based on civil
liability, whether or not predicated solely upon the federal securities laws,
would not be directly enforceable in The Netherlands. However, if the party in
whose favor such final judgment is rendered brings a new suit in a competent
court in The Netherlands, such party may submit to the Dutch court the final
judgment which has been rendered in the United States. If the Dutch court finds
that the jurisdiction of the federal or state court in the United States has
been based on grounds which are internationally acceptable and that proper legal
procedures have been observed, the Dutch court will, in principle, give binding
effect to the final judgment which has been rendered in the United States unless
such judgment contravenes Dutch principles of public policy. Based on the
foregoing, there can be no assurance that U.S. investors will be able to enforce
against us, members of our Managing or Supervisory Boards, officers or certain
experts named herein who are residents of The Netherlands or countries other
than the United States any judgments obtained in U.S. courts in civil and
commercial matters, including judgments under the federal securities laws. In
addition, there is doubt as to whether a Dutch court would impose civil
liability on us, the members of our Managing or Supervisory Boards, our officers
or certain experts named herein in an original action predicated solely upon the
federal securities laws of the United States brought in a court of competent
jurisdiction in The Netherlands against us or such members, officers or experts,
respectively.

(1)  The number of common shares beneficially owned by each shareholder is
     determined under rules promulgated by the Commission, and the information
     is not necessarily indicative of beneficial ownership for any other
     purpose. Under such rules, beneficial ownership includes any common shares
     as to which the individual has sole or shared voting power or investment
     power and also any common shares which the individual has the right to
     acquire within 60 days after June 26, 2002 through the exercise of any
     stock option or other right. The inclusion herein of such common shares,
     however, does not constitute an admission that the named shareholder is a
     direct or indirect beneficial owner of such common shares.

(2)  Patrick Weiss is the President of Xeragon, Inc.


                              Plan of Distribution

     In addition to covering the resale of the above-mentioned common shares,
this prospectus covers an indeterminate number of additional common shares as
may from time to time become issuable as a result of any stock split, stock
dividend, recapitalization, combination, merger, consolidation, distribution or
other similar transactions with respect to the 564,334 common shares discussed
above.

     Our common shares offered in this prospectus were originally issued to the
selling shareholders pursuant to exemptions from the registration requirements
of the Securities Act under Sections 4(2) thereof in connection with our
acquisition of Xeragon, Inc. In accordance with registration rights granted to
the selling shareholders in the Xeragon acquisition, we have filed a
Registration Statement on Form F-3 with the SEC in order to register the
securities for resale. The Registration Statement covers the resale of the
564,334 common shares from time to time on the Nasdaq National Market or in
privately negotiated transactions. This prospectus forms a part of the
Registration Statement. We have also agreed to prepare and file such amendments
and supplements to the Registration Statement as may be necessary to keep the
Registration Statement effective until the earlier of the date when the
securities covered by the Registration Statement may be sold under SEC Rule 144
within a three-month period or such time as all of the securities covered by the
Registration Statement have been sold by the selling shareholders. We

                                       14



have agreed to pay all reasonable fees and expenses for the registration of the
common shares. We have agreed to indemnify the selling shareholders against
certain losses, claims, damages and liabilities, including liabilities under the
Securities Act, that could arise in connection with the selling shareholders'
sales of their securities.

     Our 564,334 common shares offered in this prospectus may be offered and
sold from time to time by the selling shareholders, or by pledgees, donees,
transferees or other successors in interest selling shares received after the
date of this prospectus from a named selling shareholder as a gift, pledge,
partnership distribution or other non-sale related transfer. Such offers and
sales may be made from time to time on a stock exchange, market or trading
facility on which the securities are traded or in privately negotiated
transactions. These sales may be at prices and on terms prevailing in the
market, at prices related to the market price of our common shares or at
negotiated prices. The selling shareholders may use any one or more of the
following methods when selling the securities:

     .  ordinary brokerage transactions and transactions in which the
        broker-dealer solicits purchasers;

     .  block trades in which the broker-dealer will attempt to sell the shares
        as agent but may position and resell a portion of the block as principal
        to facilitate the transaction;

     .  purchases by a broker-dealer as principal and resale by the broker-
        dealer for its account,

     .  an exchange distribution in accordance with the rules of the relevant
        exchange;

     .  privately negotiated transactions;

     .  short sales;

     .  broker-dealers may agree with the selling shareholders to sell a
        specified number of such shares at a stipulated price per share;

     .  a combination of any such methods of sale; and

     .  any other method permitted by law.

The selling shareholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

     From time to time the selling shareholders may engage in short sales, short
sales against the box, puts and calls and other transactions in our securities,
and may sell and deliver the securities in connection with those transactions.
The selling shareholders may pledge their shares to their brokers under the
margin provisions of their customer agreements. If a selling stockholder
defaults on a margin loan, the broker may offer and sell the pledged securities
from time to time.

     Broker-dealers engaged by the selling shareholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the selling shareholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. The selling shareholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved.

     The selling shareholders and any broker-dealers or agents that are involved
in selling the securities may be considered to be "underwriters" within the
meaning of the Securities Act in connection with such sales. If so, any
commissions received by such broker-dealers or agents and any profit on the
resale of the securities purchased by them may be considered to be underwriting
commissions or discounts under the Securities Act.

     In order to comply with the securities laws of some states, the securities
must be offered or sold only through registered or licensed brokers or dealers.
In addition, in some states, the securities may not be offered or sold unless

                                       15



they have been registered or qualified for sale in that particular state or
unless an exemption from the registration or qualification requirement is
available and is complied with.

     The common shares may be offered anywhere in the world, except that such
offer may only be announced to persons who are established, domiciled or have
their residence outside the Netherlands, provided that (i) the offer and each
announcement of the offer states that the offer is not and will not be made to
persons who are resident in the Netherlands, and (ii) the offer and each
announcement thereof comply with the laws and regulations of any State where
persons to whom the offer is made are resident.

     The anti-manipulative provisions of Regulation M under the Securities
Exchange Act of 1934 may apply to sales of the common shares by the selling
shareholders.

     All proceeds from sales of the 564,334 common shares offered in the
prospectus will be the property of the selling shareholders, each of whom will
bear the expense of underwriting discounts and selling commissions, if any, and
their own related legal fees.


                                  LEGAL MATTERS

     Certain legal matters in connection with this offering will be passed upon
for us by Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., Boston,

14,000 common shares. The validity of the common shares offered hereby will be

Netherlands. Matters of Dutch tax law will be passed upon for us by Baker &
McKenzie, Amsterdam, The Netherlands.

Item 15. Indemnification of Directors and Officers

     The Registrant's Articles of Association provide for indemnification of the
Registrant's directors and officers for liabilities and expenses that they may
incur in such capacities. In general, directors and officers are indemnified
with respect to actions taken in good faith in a manner reasonably believed to
be in, or not opposed to, the best interests of the Registrant, and with respect
to any criminal action or proceeding, actions that the indemnitee had no
reasonable cause to believe were unlawful.

     The Registrant maintains insurance which insures the officers and directors
of the Registrant against certain losses and which insures the Registrant
against certain of its obligations to indemnify such officers and directors.

of Arthur Andersen LLP to the incorporation by reference of their report in this
registration statement, and the registrant has dispensed with the requirement to
file their consent in reliance upon Rule 437a promulgated under the Securities
Act. Because Arthur Andersen LLP has not consented to the incorporation by

to recover against Arthur Andersen LLP under Section 11 of the Securities Act
for any untrue statements of a material fact contained in the financial
statements audited by Arthur Andersen LLP incorporated by reference herein or
any ommissions to state a material fact required to be stated therein.

Item 17. Undertakings

A. Rule 415 Offering.

The undersigned registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
    post-effective amendment to this registration statement:

         (i)  To include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after the
         effective date of the registration statement (or the most recent post-
         effective amendment thereof) which, individually or in the aggregate,
         represent a fundamental change in the information set forth in the
         registration statement. Notwithstanding the foregoing, any increase or
         decrease in volume of securities offered (if the total dollar value of
         securities offered would not exceed that which was registered) and any
         deviation from the low or high end of the estimated maximum offering
         range may be reflected in the form of prospectus filed with the
         Commission pursuant to Rule 424(b)(S).230.424(b) of this chapter) if,
         in the aggregate, the changes in volume and price represent no more
         than a 20% change in the maximum aggregate offering price set forth in
         the "Calculation of Registration Fee" table in the effective
         registration statement; and

         (iii) To include any material information with respect to the plan of
         distribution not previously disclosed in the registration statement or
         any material change to such information in the registration statement;

                                      II-2



Provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3, and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the Registrant pursuant to Section 13 or
Section 15(d) of the 1934 Act that are incorporated by reference in the
registration statement.

    (2) That, for the purpose of determining any liability under the Securities
    Act, each such post-effective amendment shall be deemed to be a new
    registration statement relating to the securities offered therein, and the
    offering of such securities at that time shall be deemed to be the initial
    bona fide offering thereof.

    (3) To remove from registration by means of a post-effective amendment any
    of the securities being registered which remain unsold at the termination of
    the offering.

    (4) If the registrant is a foreign private issuer, to file a post-effective
    amendment to the registration statement to include any financial statements
    required by Section 210.3-19 of this chapter at the start of any delayed
    offering or throughout a continuous offering. Financial statements and
    information otherwise required by Section 10(a)(3) of the Act need not be
    furnished, provided that the registrant includes in the prospectus, by means
    of a post-effective amendment, financial statements required pursuant to
    this paragraph (a)(4) and other information necessary to ensure that all
    other information in the prospectus is at least as current as the date of
    those financial statements. Not withstanding the foregoing, with respect to
    registration statements on Form F-3 (Section 239.33 of this chapter), a
    post-effective amendment need not be filed to include financial statements
    and information required by Section 10(a)(3) of the Act or Section 210.3-19
    of this chapter if such financial statements and information are contained
    in periodic reports filed with or furnished to the Commission by the
    registrant pursuant to section 13 or section 15(d) of the Securities
    Exchange Act of 1934 that are incorporated by reference in the Form F-3.

B. Filings Incorporating Subsequent Exchange Act Documents by Reference.

The undersigned registrant hereby undertakes that, for purposes of determining
any liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to section 13(a) or section 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

C. Request for Acceleration of Effective Date.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
of 1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.

                                      II-3



                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form F-3 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Venlo, The Netherlands, on June 28, 2002.
