QIAGEN N.V. 564,334 Common Shares (par value EUR 0.01 per share) We are registering 564,334 common shares for sale by the securityholders identified in this prospectus as the selling shareholders. The selling shareholders may sell the common shares at prices and on terms determined by the market, in negotiated transactions or through underwriters. The selling shareholders are identified and information with respect to them is provided under the caption "Selling Shareholders" in this prospectus. We will not receive any of the proceeds from the sale of such shares. Investing in our common shares involves risks. See "Risk Factors" beginning on page 5. Our common shares are listed on the Nasdaq National Market under the symbol "QGENF" and on the Neuer Markt trading segment of the Frankfurt Stock Exchange under the symbol "QIA." On June 26, 2002, the last reported sale price of our common shares on the Nasdaq National Market was $11.06. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense. The date of this prospectus is June __, 2002. 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".

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. Risks and Uncertainties Regarding Forward-Looking Statements This Prospectus contains certain forward-looking statements that are subject to certain risks and uncertainties. These statements include statements regarding (i) our ability to maintain relationships with our customers and our broad range of products, (ii) our ability to stay abreast of technological developments, (iii) the size of our markets and potential markets, (iv) our ability to penetrate and expand these markets and the demand for our products, (v) our ability to increase our production efficiency as a result of expansion in our production capacity, and (vi) our liquidity. Such statements are based on management's current expectations and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. We caution investors that there can be no assurance that actual results or business conditions will not differ materially from those projected or suggested in such forward-looking statements as a result of various factors, including, but not limited to, the following: risks associated with our expansion of operations, management growth, international operations, and dependence on key personnel; intense competition; the variation in our operating results; technological change; our ability to develop and protect proprietary products and technologies and to enter into collaborative commercial relationships; our ability to integrate acquisitions of technologies and businesses; our future capital requirements; and uncertainties as to the extent of future government regulation of our business. As a result, our future development efforts involve a high degree of risk. DIVIDEND POLICY We have never paid cash dividends on our share capital. We currently intend to retain any earnings to finance the growth and development of our business and, therefore, do not intend to pay dividends on our share capital for the foreseeable future. USE OF PROCEEDS All net proceeds from the sale of the common shares being offered will go to the the selling shareholders who offer and sell their shares. Accordingly, we will not receive any proceeeds from the selling shareholders' sale of their common shares. 13 SELLING SHAREHOLDERS The following table sets forth certain information regarding the beneficial ownership of the Company's common shares as of June 26, 2002 by each selling shareholder both before and after giving effect to this offering.

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.

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.

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.
