Risk Factors

Note Regarding Forward-Looking Statements and Risk Factors

Our future operating results may be affected by various risk factors, many of which are beyond our control. Certain of the statements included in this Annual Report and the documents incorporated herein
by reference may be forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended, including statements regarding
potential future net sales, gross profit, net income and liquidity. These statements can be identified by the use of forward-looking terminology such as believe, hope, plan, intend, seek,
may, will, could, should, would, 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. 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. 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. As a result, our future success involves a high degree of risk. 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.

Risks Related to Our Business

An inability to manage our growth, manage the expansion of our operations, or successfully integrate acquired businesses could adversely affect our
business.

Our business has grown rapidly, with total net revenues increasing from $398.4 million in 2005 to $1,009.8
million in 2009. We have made several acquisitions, including our recent acquisitions of SABiosciences in December 2009, DxS Ltd. in September 2009, Corbett Life Science Pty. Ltd., or Corbett, in July 2008 and Digene Corporation, or Digene, in July
2007, and may acquire additional businesses in the future. The successful integration of acquired businesses requires a significant effort and expense across all operational areas, including sales and marketing, research and development,
manufacturing, finance and administration and information technologies.

In January 2009, we purchased land adjacent to our
facility in Germany and in August 2009 began to expand the German facilities for research and development on this new land as well as expand our production space on previously owned land adjacent to existing buildings. This expansion project is
expected to continue through 2011. In addition, we are planning for expansions at our Germantown, Maryland facility for research, production and administrative space, construction on which is expected to begin in 2010 and continue into 2012.

Such expansions increase fixed costs. These higher fixed costs will continue to be a cost of operations in the future, and until we fully utilize the additional capacity of these planned
facilities, our gross profit and operating income will be negatively impacted. We also continue to upgrade our operating and financial systems and expand the geographic area of our operations, resulting in the hiring of new employees, as well as
increased responsibility for both existing and new management personnel. The rapid expansion of our business and addition of new 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, manufacturing, sales and marketing and customer support programs, enhance our operational and financial control systems, expand, train and manage our employee base, integrate acquired businesses, 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 or acquisition successfully, and any inability to do so could have a material adverse effect on our results of
operations.

Our acquisitions expose us to new risks, and we may not achieve the anticipated benefits of acquisitions of technologies and
businesses.

During the past several years we have acquired and integrated a number of companies, including our
acquisitions of DxS Ltd. in September 2009, Explera s.r.l in August 2009, SABiosciences in December 2009, all assets of Biosystems Business from Biotage AB in October 2008, Corbett in July 2008 and Digene in July 2007, 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 operations. Acquisitions, including the
acquisitions referenced in the previous sentence, expose us to new operating and other risks, including the risks associated with the:



| |  |  | assimilation of new products, technologies, operations, sites and personnel;
| | - |  | ----------------------------------------------------------------------------



| |  |  | application for and achievement of regulatory approvals or other clearances;
| | - |  | ----------------------------------------------------------------------------



| |  |  | diversion of resources from our existing business and technologies;
| | - |  | -------------------------------------------------------------------



| |  |  | generation of revenues to offset associated acquisition costs;
| | - |  | --------------------------------------------------------------



| |  |  | implementation and maintenance of uniform standards and effective controls and procedures;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | maintenance of relationships with employees and customers and integration of new management personnel;
| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | issuance of dilutive equity securities;
| | - |  | ---------------------------------------



| |  |  | incurrence or assumption of debt;
| | - |  | ---------------------------------



| |  |  | amortization or impairment of acquired intangible assets or potential businesses; and
| | - |  | -------------------------------------------------------------------------------------



| |  |  | exposure to liabilities of and claims against acquired entities.
| | - |  | ----------------------------------------------------------------

Our failure to address the above risks successfully in the future may prevent us from achieving the anticipated benefits from any
acquisition in a reasonable time frame, or at all.

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

Rapid technological change and frequent new product introductions are typical in the markets we serve. Our future success will
depend in part on continuous, timely development and introduction of new products that address evolving market requirements. We believe successful new product introductions provide a significant competitive advantage because customers make an
investment of time in selecting and learning to use a new product and are reluctant to switch thereafter. To the extent that we fail to introduce new and innovative products, or such products suffer significant delays in development or are not
accepted in the market, we may

lose market share to our competitors, which will be difficult or impossible to regain. An inability, for technological or other reasons, to successfully develop and introduce new products could
reduce our growth rate or otherwise have an adverse effect on our business. In the past, we have experienced, and are likely to experience in the future, delays in the development and introduction of products. We cannot assure you that we will keep
pace with the rapid rate of change in our markets or that our new products will adequately meet the requirements of the marketplace, achieve market acceptance or compete successfully with competitive technologies. Some of the factors affecting
market acceptance of new products include:



| |  |  | availability, quality and price relative to competitive products;
| | - |  | -----------------------------------------------------------------



| |  |  | the timing of introduction of the new product relative to competitive products;
| | - |  | -------------------------------------------------------------------------------



| |  |  | opinions of the new products utility;
| | - |  | --------------------------------------



| |  |  | citation of the new product in published research;
| | - |  | --------------------------------------------------



| |  |  | regulatory trends and approvals; and
| | - |  | ------------------------------------



| |  |  | general trends in life sciences research, applied markets and molecular diagnostics.
| | - |  | ------------------------------------------------------------------------------------

The expenses or losses associated with unsuccessful product development activities or lack of market acceptance of our new products could
materially adversely affect our business, financial condition and results of operations.

Global economic conditions could adversely affect
our business, results of operations and financial condition.

Our results of operations could be materially affected by
general conditions in the global economy and in the global financial markets. The global financial crisis has caused extreme volatility and disruptions in the capital and credit markets. Therefore, access to financing has been adversely affected for
many businesses. A severe or prolonged economic downturn could result in a variety of risks to our business, including, for our business in particular, reductions or delays in planned improvements to the healthcare systems and research funding, or
cost-containment efforts by governments and private organizations that could lead to a reduction in future revenues, operating income and cash from operations and furthermore, as is the case for most other businesses, the following risks:



| |  |  | severely limited access to financing over an extended period of time, which may limit our ability to fund our growth strategy, could result in a need

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

Our success depends to a large extent on our ability to develop proprietary products and technologies and to establish and protect our patent
and trademark rights in these products and technologies. As of December 31, 2009, we owned 149 issued patents in the United States, 107 issued patents in Germany and 527 issued patents in other major industrialized countries. In addition, at
December 31, 2009, we had 843 pending patent applications, and we intend to file applications for additional patents as our products and technologies are developed. The patent positions of technology-based companies, including our company,
involve complex legal and factual questions and may be uncertain, and the laws governing the scope of patent coverage and the periods of

##### Table of Contents

enforceability of patent protection are subject to change. 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 tends to lag behind actual discoveries by several months. Therefore, no assurance can be given that patents will issue from any patent applications that we own or license 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 that we own or license will not be challenged, invalidated or circumvented, or that the rights granted thereunder will
provide us competitive advantages. Further, as issued patents expire, we may lose some competitive advantage as others develop competing products and as a result, we may lose revenue.

A significant portion of Human Papillomavirus, or HPV, -related intellectual property is in the public domain, while additional HPV-related
intellectual property is subject to our patents some of which will begin to expire in the next few years or are licensed to us on a non-exclusive basis. As a result, other companies have developed or may develop HPV detection tests.

Certain of our products incorporate patents and technologies that are licensed from third parties and for certain products, these
in-licensed patents together with other patents provide us with a competitive advantage. 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, and as a result, we may lose some competitive advantage and experience a loss of revenue.

We also rely on trade secrets and proprietary know-how, which we seek to protect through confidentiality agreements with our employees and
consultants. There can be no assurance that any confidentiality agreements that we have with 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 may continue to 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.

Our concentration of a large amount of revenues in a single product and a small number of customers for that product increases our dependence on that products success, our reliance on our
relationship with each of those customers, and our reliance on a diversification strategy.

We believe that revenue from
sales of our HPV test product may represent as much as 30% of our total revenues. While the ultimate decision to order that test is made by the patient in consultation with her physician, the test is performed by reference laboratories. At present,
sales to a limited number of reference laboratories account for the majority of our revenues for that product. A significant reduction in sales of this product may have a significant adverse impact on our earnings. In times of economic hardship or
high unemployment, patients may decide to forego or delay routine tests. Further, the cost of HPV testing is reimbursed to the reference laboratories by insurance providers and healthcare maintenance organizations. If these insurance companies
decide to limit the availability of payments for our test to their members, it could have a significant adverse impact on our revenues. It is possible that our dependence on revenues from this product and those customers will continue in the future.
If, going forward, we fail to diversify our product line and customer base for this product, we will continue to be at risk that the loss or under-performance of a single product or customer may materially affect our earnings.

Our sales of HPV products and our growth will also be effected by continued increases in the acceptance
of and the market for HPV screening by physicians and laboratories.

Our sales of HPV-related molecular diagnostic products
and our ability to increase sales of HPV-related molecular diagnostic products depend upon continued and increasing acceptance by physicians and laboratories of HPV screening as a necessary part of the standard of care for cervical cancer screening
and more specifically, of our HPV test products as a primary cervical cancer screening method, either alone or in conjunction with cytology-based tests (Pap tests), and the implementation of prophylactic HPV vaccinations. Pap tests have been the
principal means of cervical cancer screening since the 1940s. Technological advances designed to improve quality control over sample collection and preservation and to reduce the Pap tests susceptibility to human error may increase physician
reliance on the Pap test and solidify its market position as the most widely used screen for cervical cancer. Currently, approximately 60 million Pap tests are performed annually in the United States and we believe that 60 to 100 million
are performed annually in the rest of the world.

HPV testing applies a new molecular-based technology and testing approach
that is different from the cytology-based (reviewing cells, for instance, under a microscope) approach of the Pap test. Significant resources are required to educate physicians and laboratories about the patient benefits that can result from using
HPV test products in addition to the Pap test, and to assist laboratory customers in learning how to use our HPV test products. Using our HPV test products along with the Pap test for primary screening in the United States may be seen by some of
these customers as adding unnecessary expense to the generally accepted cervical cancer screening methodology, and therefore, we continually need to provide information to counteract this impression on a case-by-case basis. If we are not successful
in executing our marketing strategies, we may not be able to maintain or continue to grow our market share for HPV testing.

Direct-to-consumer awareness marketing programs, including television advertisements, are used because we believe that a well educated female population will work with their healthcare providers to increase the use of the HPV test. If we
are not successful in continuing to execute this marketing program, we may not be able to maintain or continue to increase the sales of our HPV tests to the extent we desire.

We are working with physician and laboratory customers and with others to develop and establish the role HPV screening will play in addition
to and in conjunction with HPV vaccination. If we are not successful in this endeavor, we may not be able to maintain or grow the market for HPV screening or maintain or increase our HPV test revenues.

We are subject to risks associated with patent litigation.

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 we use. 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 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 that we 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 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, and there can be no assurance that we would prevail in
any such proceedings.

Our ability to accurately forecast our results during each quarter may be negatively impacted by the fact
that a substantial percentage of our sales may be recorded 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, many customers 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 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. We may not have enough
information as a result of such patterns to confirm or revise our sales projections during a quarter. If we fail to achieve our forecasted revenues for a particular quarter, our stock price could be adversely affected.

Our operating results may vary significantly from period to period.

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,
the 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.

Competition could reduce our sales.

Our competition stems from traditional or home-brew methods that utilize widely available reagents and other chemicals to perform
sample and assay processing steps. We are also aware that a significant number of laboratory organizations and other companies are developing and using internally developed molecular tests. These tests, in particular if approved by the U.S. Food and
Drug Administration, or FDA, or similar non-U.S. regulatory authorities, might offer an alternative to our products that could limit the laboratory customer base for our products. The success of our business depends in part on the continued
conversion of current users of such traditional methods and home brew tests to our sample and assay technologies and products. There can be no assurance, however, as to how quickly such conversion will occur, if at all.

We also have experienced, and expect to continue to experience, increasing competition in various segments of our business from companies
providing competitive pre-analytical and other products. The markets for certain of our products are very competitive and price sensitive. Other product suppliers have significant financial, operational, sales and marketing resources, and experience
in research and development. These and other companies may have developed or could in the future develop new technologies that compete with our products or even render our products obsolete. If a competitor develops superior technology or
cost-effective alternatives to our kits and other products, our business, operating results and financial condition could be materially adversely affected.

We believe that customers in the market for pre-analytical solutions and assay technologies display a significant amount of loyalty to their initial supplier of a particular product. Therefore, it may be
difficult to generate sales to customers who have purchased products from competitors. To the extent we are unable to be the first to develop and supply new products, our competitive position may suffer.

Reduction in research and development budgets and government funding may result in reduced sales.

Our customers include researchers at pharmaceutical and biotechnology companies, academic institutions and government and
private laboratories. Fluctuations in the research and development budgets of these researchers and their organizations for applications in which our products are used could have a significant effect on the demand for our products. Research and
development budgets fluctuate due to changes in available resources, mergers of pharmaceutical and biotechnology companies, spending priorities and institutional budgetary policies. Our business could be adversely affected by any significant
decrease in life sciences research and development expenditures by pharmaceutical and biotechnology companies, academic institutions or government and private laboratories. In addition, short-term changes in administrative, regulatory or
purchasing-related procedures can create uncertainties or other impediments which can contribute to lower sales.

In recent
years, the pharmaceutical and biotechnology industries have undergone substantial restructuring and consolidation. Additional mergers or corporate consolidations in the pharmaceutical industry could cause us to lose existing customers and potential
future customers, which could have a material adverse effect on our business, financial condition and results of operations.

A significant portion of our sales have been to researchers, universities, government laboratories and private foundations whose funding is dependent upon grants from government agencies, such as the U.S. National Institutes of Health, or
NIH, and similar agencies. Although the level of research funding has increased during the past several years, we cannot assure you that this trend will continue. Government funding of research and development is subject to the political process,
which is inherently fluid and unpredictable. The predictability of our revenues may be adversely affected if our customers delay purchases as a result of uncertainties surrounding the approval of government or industrial budget proposals. Also,
government proposals to reduce or eliminate budgetary deficits have sometimes included reduced allocations to the NIH and other government agencies that fund research and development activities. A reduction in government funding for the NIH or other
government research agencies could seriously and negatively impact our business.

We may encounter delays in receipt, or limits in the
amount, of some European reimbursement approvals and public health funding, which will impact our ability to grow revenues in these markets.

Outside the U.S., third-party payors are often reluctant to reimburse healthcare providers for the use of medical tests that involve new technology or novel diagnostic information. In addition,
third-party payors are increasingly limiting reimbursement coverage for medical diagnostic products and, in many instances, are exerting pressure on diagnostic product suppliers to reduce their prices. Because each third-party payor individually
approves reimbursement, obtaining such approvals is a time-consuming and costly process that requires us to provide scientific and clinical support for the use of each of our products for which we seek reimbursement to each payor separately with no
assurance that such approval will be obtained. This process can delay the broad market introduction of new products and could have a negative effect on our revenues and operating results. As a result, outside the U.S., third-party reimbursement may
not be consistently available or financially adequate to cover the cost of our products. This could limit our ability to sell our products, cause us to reduce the prices of our products or otherwise adversely affect our operating results.

We heavily rely on air cargo carriers and other overnight logistics services, and shipping delays or interruptions could harm our
business.

Our customers within the scientific research markets typically do not keep a significant inventory of our
products and consequently require overnight delivery of purchases. As such, we heavily rely on air cargo carriers and logistic suppliers. If overnight services are suspended or delayed and other delivery carriers and logistic suppliers 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.

We depend on suppliers for materials used to manufacture our products, and if shipments from these
suppliers are delayed or interrupted, we may be unable to manufacture our products.

We buy materials for our products from
many suppliers and are not dependent on any one supplier or group of suppliers for our business as a whole. However, key components of certain products, including certain instrumentation components and chemicals, are available only from a single
source. If supplies from these vendors are delayed or interrupted for any reason, we may not be able to obtain these materials timely or in sufficient quantities or qualities in order to produce certain products and our sales levels could be
negatively affected.

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

Our long-term business strategy has included entering into strategic alliances and marketing and distribution arrangements with academic,
corporate and other partners relating to the development, commercialization, marketing and distribution of certain of our existing and potential products. We may be unable to continue to negotiate such collaborative arrangements on acceptable terms,
and such relationships may not be scientifically or commercially successful. In addition, we may be unable to maintain such relationships, and our collaborative partners may pursue or develop competing products or technologies, either on their own
or in collaboration with others.

Doing business internationally creates certain risks for our business.

Our business involves operations in several countries outside of the United States. Our consumable manufacturing facilities are located in
Germany, China, Sweden and the United States, and our instrumentation facilities are located in Switzerland and Australia. We also have established sales subsidiaries in numerous countries including the United States, Germany, Japan, the United
Kingdom, France, Switzerland, Australia, Canada, the Netherlands, Sweden, Italy, Hong Kong, Singapore, Turkey, Korea, Malaysia, China, Spain, Brazil and Mexico. In addition, our products are sold through independent distributors serving more than 40
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, and if we fail to coordinate and
manage these activities effectively, our business will be adversely affected. We have invested heavily in computerized information systems in order to manage more efficiently the widely dispersed components of our operations. We use SAP as our
business information system to integrate most of our subsidiaries in the Americas, Europe, Australia and Japan.

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 these conditions, an inability to successfully manage our international operations could have a material adverse impact on our operations.

We have made investments in and are expanding our business into emerging markets and regions, which exposes us to new risks.

Recently, we have expanded our business into emerging markets in Asia and South America, and we expect to continue to focus on expanding our
business in these regions. In addition to the currency and international operation risks described above, our international operations are subject to a variety of risks including those arising out of the economy, political outlook and language and
cultural barriers in countries where we have operations or do business. In many of these emerging markets, we may be faced with several risks that are more significant than in the other countries in which we have a history of doing business. These
risks include



12



---

##### Table of Contents

economies that may be dependent on only a few products and are therefore subject to significant fluctuations, weak legal systems which may affect our ability to enforce contractual rights,
exchange controls, unstable governments, and privatization or other government actions affecting the flow of goods and currency. In conducting our business, we move products from one country to another and may provide services in one country from a
subsidiary located in another country. Accordingly, we are vulnerable to abrupt changes in customs and tax regimes that may have significant negative impacts on our financial condition and operating results.

Our business in countries with a history of corruption and transactions with foreign governments increase the risks associated with our international
activities.

As we operate and sell internationally, we are subject to the U.S. Foreign Corrupt Practices Act, or the FCPA,
and other laws that prohibit improper payments or offers of payments to foreign governments and their officials and political parties by U.S. and other business entities for the purpose of obtaining or retaining business. We have operations,
agreements with third parties and make sales in countries known to experience corruption. Further international expansion may involve increased exposure to such practices. Our activities in these countries creates the risk of unauthorized payments
or offers of payments by one of our employees, consultants, sales agents or distributors that could be in violation of various laws, including the FCPA, even though these parties are not always subject to our control. It is our policy to implement
safeguards to discourage these practices by our employees and distributors. However, our existing safeguards and any future improvements may not prove to be effective, and our employees, consultants, sales agents or distributors may engage in
conduct for which we might be held responsible. Violations of the FCPA may result in criminal or civil sanctions, which could be severe, and we may be subject to other liabilities, which could negatively affect our business, operating results and
financial condition.

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

Our senior management consists of an Executive Committee comprised of the Managing Directors and our most senior
executives responsible for core functions, the Chairman of which is Mr. Peer Schatz, our Chief Executive Officer. The loss of Mr. Schatz or any of our Managing Directors could have a material adverse effect on us. Further, although we have
not experienced any difficulties attracting or retaining key management and scientific staff, our ability to recruit and retain qualified skilled personnel 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 by existing personnel 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 terms acceptable to us, if at all.

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



| |  |  | marketing, sales and customer support efforts;
| | - |  | ----------------------------------------------



| |  |  | research and development activities;
| | - |  | ------------------------------------



| |  |  | expansion of our facilities;
| | - |  | ----------------------------



| |  |  | consummation of possible future acquisitions of technologies, products or businesses;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | demand for our products and services; and
| | - |  | -----------------------------------------

##### Table of Contents

| |  |  | repayment or refinancing of debt.
| | - |  | ---------------------------------

We currently anticipate that our short-term capital requirements will be satisfied by our results of operations. However, as of December 31, 2009, we had outstanding loan facilities of approximately
$475.0 million, of which $50.0 million will become due in July 2010, $75.0 million will become due in July 2011, and $350.0 million will become due in July 2012. As of December 31, 2009, we also had additional long-term debt
obligations of $445.0 million, of which $145.0 million will become due in July 2011 and $300.0 million will become due in November 2012. Furthermore, as of December 31, 2009, we have capital lease obligations, including the current portion, of
$31.0 million, that expire in various years through 2018. We currently do not foresee that this will happen, but if at some point in time our existing resources should be insufficient to fund our activities, we may need to raise funds through public
or private debt or equity financings. Such additional funds may then not be available or, if available, not on terms acceptable to us. If adequate funds are then not available, we may have to reduce or delay expenditures for research and
development, production, marketing, capital expenditures and/or acquisitions, which could have a material adverse effect on our business. To the extent that additional capital is raised through the sale of equity or convertible securities, the
issuance of such securities could result in dilution to our shareholders.

An impairment of goodwill and intangible assets could reduce our
earnings.

At December 31, 2009, our consolidated balance sheet reflected approximately $1.3 billion of goodwill and
approximately $752.3 million of intangible assets. Goodwill is recorded when the purchase price of a business exceeds the fair market value of the tangible and separately measurable intangible net assets. U.S. generally accepted accounting
principles, or U.S. GAAP, generally requires us to test goodwill for impairment on an annual basis or when events or circumstances occur indicating that goodwill might be impaired. Long-lived assets, such as intangible assets with finite useful
lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If we determine that any of our goodwill or intangible assets were impaired, we would be required to take an
immediate charge to earnings.

Our strategic equity investments may result in losses.

We have made and may continue to make strategic investments in complementary businesses as the opportunities arise. We periodically review
the carrying value of these investments for impairment, considering factors such as the most recent stock transactions, book values from the most recent financial statements, and forecasts and expectations of the investee. The results of these
valuations may fluctuate due to market conditions and other conditions over which we have no control. Estimating the fair value of non-marketable equity investments in life science companies is inherently subjective. If actual events differ from our
assumptions and other than temporary unfavorable fluctuations in the valuations of the investments are indicated, it could require a write-down of the investment. This could result in future charges on our earnings that could materially impact our
results of operations. It is uncertain whether or not we will realize any long-term benefits from these strategic investments.

Exchange
rate fluctuations may adversely affect our business and operating results.

Since we currently market our products in over
40 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 when
incurred. We hedge a portion of the anticipated cash flow that we expect to exchange into other currencies, subject to our short-term financing needs. 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



14

##### Table of Contents

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 have a significant amount of long-term debt which may adversely affect our financial condition.

We have a significant amount of debt which carries with it significant debt service obligations. A high level of indebtedness increases the
risk that we may default on our debt obligations. We cannot assure you that we will be able to generate sufficient cash flow to pay the interest on our debt or that future working capital, borrowings or equity financing will be available to repay or
refinance such debt. If we are unable to generate sufficient cash flow to pay the interest on our debt, we may have to delay or curtail our research and development programs. The level of our indebtedness could, among other things:



| |  |  | make it difficult for us to make required payments on our debt;
| | - |  | ---------------------------------------------------------------



| |  |  | make it difficult for us to obtain any necessary financing in the future for working capital, capital expenditures, debt service requirements or other
purposes;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | make us more vulnerable in the event of a downturn in our business.
| | - |  | -------------------------------------------------------------------

The time and expense needed to obtain regulatory approval and respond to changes in regulatory requirements could adversely affect our ability to commercially distribute our products and generate
revenue therefrom.

We 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.

Changes in the existing regulations or adoption of new requirements or policies could adversely affect our ability to sell our approved
products or to seek to introduce new products in other countries around the world. Sales volumes of certain products in development may be dependent on commercial sales by us or by purchasers of our diagnostic and pharmaceutical products, which will
require pre-clinical studies, clinical trials and other regulatory clearance. Such trials will be subject to extensive regulation by governmental authorities in the United States, including the FDA, international agencies and agencies in other
countries with comparable responsibilities. These trials involve substantial uncertainties and could impact customer demand for our products. In addition, certain products, especially our products intended for use in in vitro diagnostics
applications, are dependent on regulatory or other clearance. For example, since the European Union Directive 98/79/EC on in vitro diagnostic medical devices, or EU-IvD-D, went into effect on December 7, 2003, all products and kits which are
used for in vitro diagnostic applications must be compliant with this directive. In addition to high-risk products such as HIV testing systems (list A of Annex II of the directive) or blood glucose testing systems (list B of Annex II of the
directive), and nucleic acid purification products, which are used in diagnostic workflows, are affected by this regulatory framework. The major goals of this directive are to standardize the diagnostic procedures within the European Union, to
increase reliability of diagnostic analysis

##### Table of Contents

and to enhance patients safety through the highest level of product safety. These goals are expected to be achieved by the enactment of a large number of mandatory regulations for product
development, production, quality control and life cycle surveillance. Our failing to obtain any required clearance or approvals may significantly damage our business in such segments.

Additionally, we may be required to incur significant costs to comply with laws and regulations in the future, and changes or additions to
existing laws or regulations may have a material adverse effect upon our business, financial condition and results of operations.

Several of our key products and programs are medical devices subject to extensive regulation by the FDA under the Federal Food, Drug and Cosmetic Act, and we plan to apply for FDA clearance as medical devices for additional products in the
future. Governmental bodies in other countries also have medical device approval regulations which are becoming more extensive. Such regulations govern the majority of the commercial activities including the indications for which these products can
be used, product development, product testing, product labeling, product storage, use of these products with other products and the manufacturing, advertising and promotion of these products for the approved indications. Compliance with these
regulations is expensive and time-consuming. Certain of our HPV test products were the first to obtain approval for regulated applications for HPV testing in the United States and in many countries in Europe, which adds to our expense and increases
the degree of regulatory review and oversight. The expense of submitting regulatory approval applications in multiple countries as compared to our available resources will impact the decisions we make about entering new markets.

Each medical device that we wish to distribute commercially in the United States will likely require either 510(k) clearance or pre-market
approval from the FDA prior to marketing the device for in vitro diagnostic use. Clinical trials related to our regulatory submissions take years to execute and are a significant expense. The 510(k) clearance pathway usually takes from three to
twelve months, but can take longer. The pre-market approval pathway is much more costly, lengthy and uncertain and can take from one to three years, or even longer. It took more than four years to receive pre-market approval to offer our current
generation HPV test product to test for the presence of HPV in women with equivocal Pap test results and pre-market approval to use our HPV test as a primary adjunctive cervical cancer screening test to be performed in conjunction with the Pap test
for women age 30 and older. The regulatory time span increases our costs to develop new products and increases the risk that we will not succeed in introducing or selling new products in the United States.

Our cleared or approved devices, including our diagnostic tests and related equipment, are subject to numerous post-approval requirements.
We are subject to inspection and marketing surveillance by the FDA to determine our compliance with regulatory requirements. If the FDA determines that we have failed to comply, it can institute a wide variety of enforcement actions, ranging from a
public warning letter to more severe sanctions such as fines, injunctions and civil penalties, recall or seizure of our products, operating restrictions, partial suspension or total shutdown of production, denial of our requests for 510(k) clearance
or pre-market approval of product candidates, withdrawal of 510(k) clearance or pre-market approval already granted and criminal prosecution. Any enforcement action by the FDA may affect our ability to commercially distribute these products in the
United States.

Some of our test kits are sold for research use only in the United States. We do not promote these tests
for clinical diagnostic use and they are labeled For Research Use Only or RUO. If the FDA were to disagree with our designation of a product as ROU, we could be forced to stop selling that kit until the appropriate regulatory
clearance or approval is obtained.

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,



16

##### Table of Contents

private health insurers and other organizations. Governmental and other third-party payors are increasingly seeking to contain healthcare costs and to reduce the price of medical products and
services. Therefore, the biotechnology, diagnostics and pharmaceutical industries are 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, our company, could be adversely affected.

Our business exposes us to potential product liability.

The marketing and sale of our products and services for certain applications entail a potential risk of product liability, and, although we
are not currently subject to any material product liability claims, product liability claims may be brought against us in the future. Further, there can be no assurance that our products will not be included in unethical, illegal or inappropriate
research or applications, which may in turn put us at risk of litigation. We currently carry product liability insurance coverage, which is limited in scope and amount, but which we believe is currently appropriate for us. 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 be adequate to protect us against any or all potential claims or losses.

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.

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 (naamloze vennootschap), and we are organized as a holding company. Currently, our material assets are the outstanding shares of our subsidiaries. We are, therefore, 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 our Common Shares. 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.

United States civil liabilities may not be enforceable against us.

We are incorporated under Dutch law and substantial portions of our assets are located outside of the United States. In addition, certain members of our Managing and Supervisory Boards and our officers
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. 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



17

##### Table of Contents

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, or
officers 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, or our officers 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 or officers, respectively.

Our Common Shares may have a volatile
public trading price.

The market price of our Common Shares since our initial public offering in September 1996 has
increased significantly and been highly volatile. In the last two fiscal years, the price of our Common Shares has ranged from a high of $23.58 to a low of $12.52 on the Nasdaq, and a high of EUR 15.98 to a low of EUR 10.04 on the Frankfurt Stock
Exchange. In addition to overall stock market fluctuations, factors which may have a significant impact on the market price of our 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 or those of companies related to us;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | changes in government regulations or patent laws;
| | - |  | -------------------------------------------------



| |  |  | developments in patent or other proprietary rights;
| | - |  | ---------------------------------------------------



| |  |  | developments in government spending for life sciences-related research; and
| | - |  | ---------------------------------------------------------------------------



| |  |  | general market conditions relating to the diagnostics, applied testing, 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.

Holders of our Common Shares should not expect to receive dividend income.

We have not paid cash dividends since our inception and do not anticipate paying any cash dividends on our 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. Investors should not invest in our Common Shares if
they are seeking dividend income; the only return that may be realized through investing in our Common Shares is through the appreciation in value of such shares.

Shareholders who are United States residents could be subject to unfavorable tax treatment.

We may be classified as a passive foreign investment company, or a PFIC, for U.S. federal income tax purposes if certain tests are met. Our treatment as a PFIC could result in a reduction in
the after-tax return to the holders of Common Shares and would likely cause a reduction in the value of such shares. If we were determined to be a PFIC for U.S. federal income tax purposes, highly complex rules would apply to our U.S. shareholders.
We would be considered a PFIC with respect to a U.S. shareholder if for any taxable year in which the U.S.



18

##### Table of Contents

shareholder held the Common Shares, either (i) 75% or more of our gross income for the taxable year is passive income; or (ii) the average value of our assets (during the taxable year)
which produce or are held for the production of passive income is at least 50% of the average value of all assets for such year. Based on our income, assets and activities, we do not believe that we were a PFIC for U.S. federal income tax purposes
for our taxable year ended December 31, 2009 and do not expect to be a PFIC for the current taxable year or any future taxable year. No assurances can be made, however, that the Internal Revenue Service will not challenge this position or that
we will not subsequently become a PFIC.

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 our Common Shares. Under Dutch law, a company can issue shares up to its authorized share capital provided for in its articles of association. Pursuant to our Articles of Association, our authorized share capital amounts
to EUR 9.0 million, divided into 410.0 million Common Shares, 40.0 million financing preference shares and 450.0 million preference shares, with all shares having a EUR 0.01 par value. As of December 31, 2009, we had
outstanding approximately 232.1 million Common Shares plus approximately 11.3 million additional shares reserved for issuance upon exercise or release of outstanding stock options and awards, of which 7.4 million were vested. A total
of approximately 15.9 million Common Shares are reserved and available for issuances under our stock plans as of December 31, 2009, including those shares subject to outstanding stock options and awards. The majority of our outstanding
Common Shares are freely saleable except shares held by our affiliates, which are subject to certain limitations on resale. Additionally, holders of notes issued by QIAGEN Finance (Luxembourg) S.A. and QIAGEN Euro Finance (Luxembourg) S.A. are
entitled to convert their notes into approximately 26.5 million Common Shares, subject to adjustments in certain cases.

Provisions of
our Articles of Association and Dutch law and an option we have granted may make it difficult to replace or remove management and may inhibit or delay a takeover.

Our Articles of Association, or Articles, provide that our shareholders may only suspend or dismiss our Managing and Supervisory Directors against their wishes with a vote of two-thirds of the votes cast
if such votes represent more than 50% of our issued share capital unless the proposal was made by the joint meeting of the Supervisory Board and the Managing Board in which case a simple majority is sufficient. The Articles also provide that if the
members of our Supervisory Board and our Managing Board have been nominated by the joint meeting of the Supervisory Board and Managing Board, shareholders may only overrule this nomination with a vote of two-thirds of the votes cast if such votes
represent more than 50% of our issued share capital. Certain other provisions of our Articles allow us, under certain circumstances, to prevent a third party from obtaining a majority of the voting control of our Common Shares by issuing preference
shares. Pursuant to our Articles and the resolution adopted by our general meeting of shareholders on October 11, 2007, our Supervisory Board is entitled to resolve to issue preference shares in case of an intended take-over of our company by
(i) any person who alone or with one or more other persons, directly or indirectly, have acquired or given notice of an intent to acquire (beneficial) ownership of an equity stake which in aggregate equals 20% or more of our share capital then
outstanding or (ii) an adverse person as determined by the Supervisory Board. If the Supervisory Board opposes an intended take-over and authorizes the issuance of preference shares, the bidder may withdraw its bid or enter into
negotiations with the Managing Board and/or Supervisory Board and agree on a higher bid price for our shares.

In 2004, we
granted an option to the Stichting Preferente Aandelen QIAGEN, or the Foundation (Stichting), subject to the conditions described in the paragraph above, which allows the Foundation to acquire preference shares from us. The option enables the
Foundation to acquire such number of preference shares as equals the number of our outstanding Common Shares at the time of the relevant exercise of the right less one share. When exercising the option and exercising its voting rights on such
shares, the Foundation must act in our interest and the interests of our stakeholders. The purpose of the Foundation option is to prevent or delay a change of control



19

##### Table of Contents

that would not be in the best interests of us and our stakeholders. An important restriction on the Foundations ability to prevent or delay a change of control is that issuing (preference
or other) protective shares enabling the Foundation to exercise 30% or more of the voting rights without the obligation to make a mandatory offer for all shares held by the remaining shareholders is only allowed after a public offer has been
announced by a third party. In addition, the holding of such a block of shares by the Foundation is restricted to two years and as a consequence, the size of the protective stake will need to be decreased below the 30% voting rights threshold before
the two year period lapses.

Business Overview

Description of Our Business

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 sample and assay technologies and products. Our products are considered standards in areas such as pre-analytical sample preparation and assay solutions in
research for life sciences, applied testing and molecular diagnostics.

Sample
Technologies:Sample technologies are used to collect, stabilize, isolate and purify molecules such as deoxyribonucleic acid (DNA), ribonucleic acid (RNA) and proteins from any biological sample. Our sample
technologies provide access to the content of biological samples. These include solutions for the collection, stabilization, purification, handling and storage of any analyte (DNA, RNA, protein) from any sample (blood, bone, tissue, etc.). Our
sample technologies ensure that a sample is processed in a reproducible, standardized method with the highest level of quality before entering the subsequent analysis phase, for which the Company provides a broad range of assay technologies, such as
reagents and testing solutions.

Assay Technologies:Once the general group of
biomolecules or a specific subgroup has been isolated with sample technologies, assay technologies are then used to make specific target biomolecules, such as the DNA of a specific virus, visible for subsequent detection and analysis. Our assay
technologies include reagents which enable the detection of such target analytes, e.g. the DNA sequence from a specific virus, from a purified sample. We also provide closed assays, in which such assay technologies have been pre-configured to test
for

specific targets such as the influenza virus, hepatitis, HIV, HPV or herpes. We hold unique leadership positions in a wide range of tests including in HPV-testing, one of the largest and most
rapidly expanding market segments for sample and assay technologies in molecular diagnostics, and specifically, in womens health testing.

Our Products

We offer more than 500 consumable products and automated solutions and we regularly
introduce new products in order to extend the life of our existing product lines as well as to address new market opportunities. In 2009 we launched 79 new products in the area of sample & assay technologies. We sell these products to
academic research markets, to leading pharmaceutical and biotechnology companies, to molecular diagnostics laboratories as well as to customers in applied testing markets, such as forensics, animal or food testing, and pharmaceutical process
control. These products enable our customers to efficiently pursue their research and commercial goals that require the use of nucleic acids.

The main categories of our products include:



| |  |  | Consumables:
| | - |  | ------------

Our consumable products include our sample and assay technologies. Sample technologies are used to collect, stabilize, isolate and purify DNA, RNA and proteins from all biological samples such as blood or
tissue. Assay technologies like our amplification consumables or molecular diagnostic assays are used to make such isolated biomolecules visible. We offer most of our sample and assay consumable products, which can account for as much as 90% of our
business, in kit form to maximize customer convenience and reduce user error. These kits contain all necessary reagents and buffers, and a technical handbook that includes a detailed protocol and background information. Each kit is sufficient to
support a number of applications varying from one to one thousand depending on the kit. Each kit is covered by our quality guarantee.

Major applications for our consumable products are plasmid, DNA purification; RNA purification and stabilization; genomic and viral nucleic acid purification; nucleic acid transfection; polymerase chain reaction (PCR) amplification; reverse
transcription; DNA cleanup after PCR and sequencing; DNA cloning and protein purification. In 2005, we began offering validated PCR assays which allow PCR-based detection of viral, bacterial and parasite, human and animal pathogens as well as
pharmacogenomic testing and genotyping. In 2007, we acquired Digene Corporation and began offering the digene HC2 HPV Test, a signal amplified test for the Human Papillomavirus for use in cervical cancer screening programs. The majority of our
assays is validated with either manual or automated sample preparation from QIAGEN and CE-labeled according to the IvD-Directive in the EU.



| |  |  | Instrumentation:
| | - |  | ----------------

Our instrumentation systems automate the above mentioned consumables in low, medium or high throughput scale as well as reaction set-up, allowing customers to perform reliable low- to high-throughput
nucleic acid sample preparation, assay setup and other laboratory tasks.

Our automated systems offer walk-away automation of
sample and assay technologies in low, medium or high throughput scale, as well as reaction set-up and other laboratory tasks. In early 2007, we launched the QIAcube, a novel sample processing platform incorporating novel and proprietary technologies
which allow users in research in life sciences, applied testing and molecular diagnostics to fully automate the processing of almost all our consumable sample technology products. The QIAcube received the distinguished New Product Award, or NPA,
Designation of the Association for Laboratory Automation, or ALA, in February, 2007 and the QIAsymphony, which was introduced in January 2008, received the ALA NPA in 2008.

##### Table of Contents

Also in early 2008, we released our QIAxcel, an innovative automated system. This system can
replace tedious and time-consuming methods of nucleic acid separation in low- to high-throughput laboratories and can be used for the detection of results following the use of assay technologies. QIAxcel, which is designed to take the place of
traditional slab-gel analysis, is characterized by an unprecedented sensitivity and time to results.

In 2008, we acquired
Corbett, who is best known for having developed the worlds first rotary real-time PCR cycler system, the Roto-Gene Q, a system used to detect real-time polymerase chain reaction (PCR) reactions. Real time PCR reactions are assay technologies
which make specific sequences of DNA and RNA, targets visible through amplification and quantifiable through real-time measurement of such amplification. The addition of this proprietary PCR detection technology extends QIAGENs real time PCR
molecular testing solution portfolio and enhances QIAGENs options to offer sample and assay technology solutions spanning from sample to result.

Also in 2008, we acquired the Biosystems Business of Biotage, best known for having pioneered Pyrosequencing®, which has become a fundamental assay technology in next-generation sequencing. Pyrosequencing is a patented assay technology that in special formats can achieve
significantly longer runs and can be employed in a massively parallel design to address the needs for applications such as high volume data generation in whole genome sequencing applications. In its widely used standard format, this technology
provides the opportunity to read DNA-sequences up to 100 base pairs in real time and at a price per read in the single dollar range.

In January 2010, we acquired ESE GmbH, a privately held developer and manufacturer of portable, battery operated, ultra-fast time to result, multiplex UV and fluorescence optical measurement devices. These fluorescence detection
systems are utilized for point of need testing in healthcare and applied testing markets enabling low-throughput molecular testing in practices, emergency rooms, remote field areas, and other settings where a laboratory infrastructure is not
accessible and fast turnaround is required.

In addition, key programs currently underway include the further development of
our modular, medium throughput QIAsymphony platform and the related sample and assay technologies. This system features specifications such as random access and continuous load capabilities and is designed to ultimately allow fully integrated
processing of a wide range of molecular tests  from sample to result. Also, further work is continuing on our next generation high throughput of molecular testing platform, the QIAensemble system. The QIAensemble system will automate most all
steps in the workflow for high throughput testing and its menu will also include our new version of our HPV tests.



| |  |  | Other:
| | - |  | ------

A very small part of our business revenues comes from custom services, such as whole genome amplification services, DNA sequencing, and non-cGMP DNA production on a contract basis. We also sell and/or license technology.

Research and Development

By focusing our resources on our core expertise Sample & Assay Technologies and due to the size of the markets for products that utilize this core expertise, we can invest more in research and development on our core
application area than we believe is typical in our industry. Approximately 700 employees in research and development, who work in six centers of excellence on three different continents, constantly develop new applications that push the frontiers of
science further. Our investment in research and development accounts for more than 10% of our sales. Our total research and development expenses in 2009, 2008 and 2007 were approximately $107.9 million, $97.3 million, and $64.9 million,
respectively. We have fast, proven innovation cycles, with approximately five percent of 2009 revenue growth stemming from new products launched in 2009. Our comprehensive intellectual property portfolio spans over 700 granted patents and more than
800 pending applications.

##### Table of Contents

Our product development efforts are focused on expanding our existing products and
developing innovative new products in selected areas where we have expertise and have identified substantial unmet market needs. We intend to maintain our technology leadership position through investments in product improvements, product
extensions, and innovative new approaches. We believe that improvements in instrumentation will strengthen our leadership position in the automation of sample and assay technology applications and generate an increased demand for our consumable
products.

Sales and Marketing

We market our products in more than 40 countries throughout the world. We have established subsidiaries in the markets that we believe have the greatest sales potential in the Americas, Europe, Australia,
and throughout Asia. We have established a network of highly experienced marketing personnel and employ a dedicated field sales force of over 1,200 people, who sell our products and provide direct support to customers. A significant number of our
marketing and sales staff is experienced scientists with academic degrees in molecular biology or related areas. We also have specialized independent distributors and importers.

Our marketing strategy is focused on providing high-quality products that offer customers unique advantages, coupled with a commitment to
technical excellence and customer service. We have developed a range of marketing tools designed to provide customers with direct access to technical support and to inform them of new product offerings, as well as to enhance our reputation for
technical excellence, high-quality products, and commitment to customer service. One such tool is our technical service hotline, which allows existing or potential customers to discuss, via phone and e-mail, a wide range of technical questions
regarding our products and related molecular biology procedures with Ph.D. and M.Sc. scientists in our technical service group, who provide advice and training. Frequent communication with customers enables us to identify market needs, to gain early
insight into new developments and business opportunities, and to respond with new products.

To enhance the knowledge base of
clinicians and to provide for physician-directed marketing of our products, we have sales representatives dedicated to educating physicians, nurses and other healthcare professionals about the benefits of HPV testing using our
technologies. Additionally, we have implemented direct to consumer (DTC) advertising campaigns designed to educate women about the link between HPV and cervical cancer and the availability of our HPV Test.

We also distribute several publications, including our annual catalog, to existing and potential customers worldwide, providing new product
information, product updates, and articles contributed by customers and by our scientists about existing and new applications for our products. In addition, we advertise in leading scientific and clinical journals such asScience,and
hold numerous scientific seminars, in which our scientists present technical information at leading clinical, academic and industrial research institutes worldwide. We conduct direct mail campaigns to announce new products or offer special sales
promotions, and also offer various personalized electronic newsletters for our worldwide customers that provide helpful hints and information for molecular biology applications. Our web site (www.qiagen.com) contains a full on-line product
catalog and ordering system, as well as a host of support tools, scientific design tools and other resources. Some information is available on our website in French, German and Korean to support these local
markets. In addition, we have full Japanese and Chinese language versions of our site. The information contained in, or that can be accessed through, our website is not part of this Annual Report.

In addition to keeping our customers informed of new product offerings, we also offer an inventory consignment program. The QIAcabinet is a
storage cabinet owned by us and placed in customer laboratories at their request. The QIAcabinet is stocked with our products, offering customers the convenience of immediate access, thereby reducing product reorder procedures and shipping costs. We
monitor cabinet inventory and bill the customers at regular intervals as the products are used. We believe that our QIAcabinet helps us maintain our competitive position while also reducing distribution costs and increasing our visibility in the
laboratory.

Principal Markets

From our inception, we have believed that sample and assay technologies for nucleic acids and proteins would play an increasingly important
role in cutting-edge molecular biology and that major new commercial uses of nucleic acids would be developed. We have been supplying customers with proprietary products for the processing of nucleic acids since 1986. Customers include major
academic institutions and governmental laboratories, such as the NIH, as well as leading pharmaceutical and biotechnology companies. In addition, fundamental developments in recent years have created significant new opportunities for us in the
emerging markets of nucleic acid-based molecular diagnostics, such as HPV-testing or personalized healthcare, and applied testing (or the use of molecular diagnostics outside of human healthcare), such as forensics, veterinary diagnostics, testing
of genetically modified organism, or GMO, and other food testing, drug discovery and development. In response to these opportunities, we are currently targeting our products and marketing activities to each of these markets.

Research Market

The
worldwide research market for nucleic acid and protein separation and purification products is comprised of an estimated 45,000 academic and industrial research laboratories with more than 400,000 researchers from leading academic institutions,
diagnostics companies and laboratories, biotechnology companies and pharmaceutical companies. A substantial portion of this market continues to utilize traditional, labor intensive, manual methods for nucleic acid separation and purification, and we
estimate that 15 percent of all molecular biology research time is spent on such processes. We recognized the opportunity to replace the traditional methods with reliable, fast, highly reproducible, and high-quality nucleic acid separation and
purification technologies and products. We concentrated our product development and marketing efforts on this market and now offer over 500 nucleic acid sample processing products to customers. We also offer a broad and innovative portfolio for the
expression, purification and fractionation of proteins. We believe that we are the technology leader in this growing research market and that we are well positioned to increase sales and expand our share of the research market as laboratories
continue to convert from traditional methods to newer technologies such as ours. Based on estimates of the number of sample preparations being performed each year, we believe that the potential worldwide research market for our nucleic acid
purification products exceeds $1 billion, as the majority of the market currently uses traditional methodology. In addition, we believe that an additional $800 million is spent annually in this market on PCR enzymes and reagents. We have expanded
our product base for assay technologies such as PCR amplification and reverse transcription and continue to develop products for the PCR-related market segment. In 2005, we were one of the first companies to enter into a broad licensing agreement
with Applied Biosystems Group regarding real-time PCR technology. This agreement enhances our value as a leading supplier of a broad range of real-time PCR technologies. These real-time PCR technologies are optimized for use with our market- and
technology-leading preanalytical solutions. Our PCR reagent portfolio is also a critical component for ready-to-use real-time PCR assays which we offer and which are linked to our innovative RNAi assay offering. Finally, during 2008, through our
acquisition of Corbett, we acquired the worlds first rotary real-time PCR cycler system, the Roto-Gene Q, a system used to detect real-time PCR reactions which make specific sequences of DNA and RNA targets visible through amplification and
quantifiable through real-time measurement of such amplification. The addition of this proprietary PCR detection technology extends our molecular testing solution portfolio and enhances our options to offer sample and assay technology solutions
spanning from sample to result.

Molecular Diagnostics Market

We believe that the molecular diagnostics market represents a significant market for nucleic acid sample and assay technology products. We
believe that the advent of PCR and other amplification technologies has made the prospect of nucleic acid-based molecular diagnostics feasible. Molecular diagnostics have fundamental advantages over traditional diagnostic technologies, such as
immunoassays, in potential applications and clinical specificity and sensitivity.

##### Table of Contents

This new generation of molecular diagnostics can be used, for example, to detect or identify
micro-organisms, cancer cells, bacteria and viruses by searching for their specific nucleic acid sequences. In order to prove that a disease is present in a patient, the unique sequence of the target nucleic acid causing the disease must be known,
and either the sequence in the sample must be amplified (target amplification) or the signal from the DNA must be amplified (signal amplification) to facilitate detection. Potential commercial applications for nucleic acid-based molecular
diagnostics include infectious disease diagnostics in bio banks, HLA typing for bone marrow and organ transplantation, genetic testing for predisposition to cancers and other common diseases, and genetic fingerprinting of humans, animals
and plants.

We believe clinical sensitivity and specificity can be greatly enhanced by using nucleic acid-based information.
In many cases, conventional diagnostic tests also lack the clinical sensitivity and specificity to provide definitive diagnoses during the early stages of disease. Clinical sensitivity is typically regarded as the measure of a tests ability to
accurately detect the presence of disease. A false negative test result can lead to providing a negative or normal diagnosis to a patient who has the disease. Clinical specificity is typically regarded as the measure of a tests ability to
correctly identify the absence of disease when it is not present. A false positive test result can lead to providing a positive or abnormal diagnosis to a patient who does not have disease.

For detection of HPV, we sell our products in the United States primarily for the two FDA-approved indications: adjunctive primary screening
with a Pap test for women age 30 and older, and follow-up testing of equivocal Pap test results in women of any age. In Europe and the rest of the world, HPV testing is in varying stages of research and adoption, with most use limited to follow-up
for equivocal Pap tests. We are aware of an increasing number of clinical trials being conducted to explore the use of HPV testing for primary screening, both with a Pap test or as a stand-alone primary screen, as well as for proof of clearance or
cure after treatment for diagnosed cervical disease or cancer.

The success of molecular diagnostics will depend on the
ability to analyze purified nucleic acid samples from a variety of specimens, including blood, tissue, body fluids and stool, and on automation so that hundreds of samples can be handled concurrently. Other key factors will be the convenience,
versatility, reliability and standardization of the nucleic acid separation and purification procedures. Our automated systems series has been developed to handle low-, medium-, and high-throughput nucleic acid sample preparation and handling tasks
in molecular biology laboratories, clinical laboratories, blood banks, forensic projects, and genomics projects. Nucleic acid samples purified on our instruments are ready for use in the demanding and sensitive downstream assays performed in
molecular diagnostic applications. We offer closed and open assay technologies. The open assay technologies, such as real-time PCR or endpoint PCR, contain PCR reagents. Closed assays, diagnostics with predefined targets, include Multiplexing and
other pathogen detection assays. In order to broadly address the molecular diagnostics market, in 2005, we acquired artus Gesellschaft fur molekularbiologische Diagnostik und Entwicklung mbH, subsequently renamed QIAGEN Hamburg GmbH, which offers a
broad range of real-time PCR assays for viral and bacterial pathogen detection that are complementary to our sample preparation kits. The majority of these assays are validated with either manual QIAamp sample preparation or automated
MagAttract sample preparation and CE-labeled according to the EU-IvD-D. Assays are marketed directly to end customers by our sales channels and selected assays are marketed by major diagnostic partners with access to customers complementary to our
customers. In addition, we intend to enter into partnerships or other agreements with established companies in the molecular diagnostics market in order to broaden the distribution of our products.

We view the molecular diagnostics market as having 4 key submarkets: Prevention, Profiling, Personalized Healthcare and Point-of-Need.
Molecular diagnostics in the Prevention submarket are typically used in disease screening in non-symptomatic patients, such as HPV testing in primary cervical cancer screening. In the Profiling submarket, diagnostics are typically used to screen
symptomatic patients for disease, such as the use of our flu testing solutions in patients presenting flu-like symptoms. In Personalized Healthcare, diagnostics are used in order to stratify the population to determine which patients are most likely
to respond positively to a particular



26

##### Table of Contents

therapy, such as KRAS testing in conjunction with anti-body linked chemotherapies for the treatment of colorectal cancer. Finally, the Point-of-Need diagnostics are used in practices, emergency
rooms, remote field areas, and other settings where a laboratory infrastructure is not accessible and fast turnaround is required.

We expect molecular diagnostic tests at large to create a fundamental shift in both the practice of medicine and the economics of the diagnostics industry. Molecular-based diagnostic tests are expected to create an increased emphasis on
preventative and predictive molecular medicine. In the Personalized Healthcare segment, physicians will be able to use these tests for the early detection of disease and to treat patients on a personalized basis, allowing them to select the most
effective therapy with the fewest side effects. In addition, the relatively straight-forward format and significant automation capabilities of our tests allow ease of laboratory use, reducing overall processing costs. Additionally, the relatively
straightforward format and fast turnaround time of molecular tests allows for near patient testing in the Point-of-Need diagnostics segment.

Applied Testing Market

We believe that emerging applied testing markets (which we define as the
molecular diagnostics market outside of human healthcare), such as forensics, veterinary and food, offer great opportunities for standardized sample preparation and assay solutions. Successes in crime cases due to DNA analyses, public debates about
GMO and food safety as well as bioterrorism risks, have increased the value of the use of molecular-based methods. These methods are performed by well trained researchers in fully equipped laboratories as well as by less trained personnel calling
for easy-to-use, reproducible and standardized methods. Our manual DNA and RNA purification methods and the automated solutions on QIAsymphony, BioRobot EZ1, BioSprint 15 and 96, as well as our amplification enzymes and quantitative assays address
the needs in these markets. We market a range of assays to end users in applied testing markets, such as veterinary diagnostics and biodefense laboratories.

Seasonality

Our business does not experience predictable
seasonality. Historically, a significant portion of our sales have been to researchers, universities, government laboratories and private foundations whose funding is dependent upon grants from government agencies, such as the NIH and similar
agencies. To the extent that our customers experience increases, decreases or delays in funding arrangements and budget approvals, and to the extent that any of our customers activities are slowed, such as during vacation periods or due to
delays in the approval of governmental budgets, including the U.S. federal governments budget, we may experience fluctuations in sales volumes during the year or delays from one period to the next in the recognition of sales.

Intellectual Property, Proprietary Rights and Licenses

We have made and expect to continue to make investments in intellectual property. In the years ended December 31, 2009, 2008 and 2007,
our purchases of intangible assets have totaled approximately $17.2 million, $18.5 million, and $24.1 million, respectively. We do not depend solely on any individual patent or technology owned or licensed by us. We are, however, significantly
dependent in the aggregate on technology that we own or license. Therefore, we consider the protection of our proprietary technologies and products as one of the major keys to the success of our business. We rely on a combination of patents,
licenses and trademarks to establish and protect our proprietary rights in our technologies and products. We currently own 149 issued patents in the United States, 107 issued patents in Germany and 527 issued patents in other major industrialized
countries, and have 843 pending patent applications. Our policy is to file patent applications in Western Europe, the United States and Japan. U.S. patents have a term of 17 years from the date of issue for patents issued from applications submitted
prior to June 8, 1995, and 20 years from the date of filing of the application in the case of patents issued from applications submitted on or after June 8, 1995. Patents in most other countries have a term of 20 years from the date of
filing the patent application. We intend to aggressively prosecute and enforce our patents and otherwise protect our proprietary technologies. We also rely on trade secrets, know-how, continuing technological innovation and licensing opportunities
to develop and maintain our competitive position.

Our practice is to require employees, consultants, outside scientific
collaborators, sponsored researchers and other advisors to execute confidentiality agreements upon the commencement of their relationships with us. These agreements provide that all confidential information developed by or made known to the
individual during the course of the individuals relationship with us is to be kept confidential and not disclosed to third parties, subject to a right to publish certain information in scientific literature in certain circumstances and to
other specific exceptions. In the case of our employees, the agreements provide that all inventions conceived by the individual in the course of their employment will be our exclusive property.

See Risk Factors included in Item 3 above for details regarding risks related to our reliance on patents and proprietary
rights.

Partnerships, Alliances and Acquisitions

Our strategy includes the use of strategic alliances to augment our product development efforts with complementary technologies and to
leverage our marketing and distribution capabilities with respect to select market opportunities. In order to expand our business, we also intend to continue to pursue strategic investments in our acquisitions of complementary businesses and
technologies as the opportunities arise. We currently develop integrated solutions for and together with many manufacturers from pharma and diagnostics.

Competition

We believe that our primary competition in sample
technology products involves traditional separation and purification methods, such as phenol extraction, cesium chloride density gradient centrifugation, and precipitation. These methods utilize widely available reagents and other chemicals supplied
by companies, such as Sigma-Aldrich Corp. and Roche Diagnostics GmbH (Applied Sciences Division). We compete with such methods through our innovative technologies and products, which offer a comprehensive solution for nucleic acid collection,
pre-treatment, separation and purification needs and provide significant advantages over traditional methods with respect to speed, reliability, convenience, reproducibility and ease of use.

We also experience, and expect to continue to experience, competition in different segments of our business from other companies providing
sample preparation products in kit form and assay solutions. These competitors include, but are not limited to: Promega Corp., Millipore Corp., Roche Diagnostics, and Macherey-Nagel GmbH for nucleic acid separation and purification; Life
Technologies Corp. (created through the merger of Invitrogen Corp. and Applied Biosystems Inc. in 2008) and Promega Corp. for assay solutions; Life Technologies Corp. and Promega Corp. for transfection reagents; and Sigma-Aldrich Corp. and Fisher
Scientific for protein fractionation products. We believe that our proprietary technologies and products offer significant advantages over competitors products with regard to purity, speed, reliability and ease-of-use.

In respect to our HPV franchise, we face competition from well established diagnostic technologies, such as cytology, and from emerging HPV
testing approaches, such as signal amplified testing, research-based PCR, other indicators of disease and other traditional testing methods developed by laboratories. Our competitors include companies, such as Roche Diagnostics, Gen-Probe, Inc., and
Hologic, Inc. (formerly Third Wave Technologies, Inc.), which are developing and/or marketing FDA approved HPV testing products, and manufacturers of liquid-based Pap tests, such as Hologic, Inc. (formerly Cytyc Corp.) and Beckton Dickinson and
Company (formerly TriPath Imaging). These tests, if approved by the FDA or similar non-U.S. regulatory authorities, may offer an alternative to our products and, considering the increasing acceptance of the importance of HPV testing, we expect
competition to intensify.

With respect to our other diagnostic test products, the medical diagnostics and biotechnology
industries are subject to intense competition. Some of our products, such as our tests for Chlamydia, Gonorrhea, hepatitis B virus, herpes simplex virus and cytomegalovirus, compete against existing screening, monitoring and diagnostic technologies,
including tissue culture and antigen-based diagnostic methodologies. Our competitors for gene-based diagnostic probes include Roche Diagnostics, Abbott Laboratories, Siemens and Gen-Probe. We believe the primary competitive factors in the market for
gene-based probe diagnostics and other screening devices are clinical validation, performance and reliability, ease of use, standardization, cost, proprietary position, the competitors share of the existing market, access to distribution
channels, regulatory approvals, and availability of reimbursement.

We believe that our competitors do not have the same
comprehensive approach to sample and assay technologies and therefore cannot provide the broad range of technologies and depth of products and services that we offer. With our complete range of manual and fully automated solutions, we believe we
offer the value of standardization of procedures and therefore more reliable results. We also believe that our integrated strategic approach of sample and assay technologies gives us a competitive advantage. The quality of sample



29

##### Table of Contents

preparationa field in which we have a unique market and leadership positionis a key prerequisite for reliable molecular assay solutions which increasingly are being applied in
emerging markets, such as applied testing and molecular diagnostics. Regarding our HPV test products, we believe we have a competitive advantage as a multitude of clinical trials, encompassing over one million women, have validated that our HPV test
products, when used alone or in conjunction with the Pap test, have demonstrated their ability to enable significant diagnostic capabilities for cervical disease and cancer due to high clinical sensitivity and high negative predictive value. In
addition to the industry leading clinical performance of our assay, considering the high volume needs of the HPV testing market, we believe additional competitive factors in the HPV testing market relate to automation, including performance and
reliability, ease of use, standardization, cost, proprietary position, and regulatory approvals.

Our existing and potential
competitors may be in the process of seeking FDA or foreign regulatory approvals for their respective products. Our continued future success will rely in large part on our ability to maintain our technological advantage over competing products,
expand our market presence and preserve customer loyalty. There can be no assurance that we will be able to compete effectively against our past, present or future competitors or that development by others will not render our technologies or
products non-competitive.

Suppliers

As part of our quality assessment procedures, we periodically evaluate the performance of our raw material suppliers, potential new alternative sources of such materials, and the risks and benefits of
reliance on our existing suppliers. We buy materials for our products from many suppliers, and are not dependent on any one supplier or group of suppliers for our business as a whole. Raw materials generally include chemicals, raw separation media,
biologics, plastics and packaging. Raw materials are generally readily available at competitive, stable prices from a number of suppliers. Certain raw materials are produced under our specifications, so we closely monitor stock levels to maintain
adequate supplies. We believe we maintain inventories of raw materials at a sufficient level to ensure reasonable customer service levels and to guard against normal volatility in availability.

Government Regulations

We are not subject to direct regulation other than regulation generally applicable to businesses pursuant to various laws and regulations in effect in the different jurisdictions in which we operate, including laws and regulations
applicable to environmental matters, such as the handling and disposal of hazardous wastes. Our research and development activities involve the controlled use of small amounts of hazardous materials, chemicals and radioactive compounds. Although we
believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by applicable regulations, such as the United States Occupational Safety and Health Administrations, or OSHA, Hazard
Communication and Occupational Exposure to Hazardous Chemicals in Laboratories standards, 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.

We also comply with the OSHA
Bloodborne Pathogens standard and the Center for Disease Control/National Institutes of Health Biosafety in Microbiological and Biomedical Laboratories standards for the handling of biological materials and comply with the United States Department
of Transportation and International Air Transport Association regulations for the shipping of our kits which contain materials classified as hazardous. There are other federal, state and local laws and regulations applicable to our business,
including those of the United States Environmental Protection Agency and the Maryland Department of the Environment. However, we do not expect that compliance with governmental regulations to which we are subject will have a material effect on our
capital expenditures, earnings or competitive positions.

International sales of in vitro diagnostic (IVD) medical
devices are subject to the regulatory requirements of each country or defined economic region, such as the European Union. The regulatory review process varies



30



---

##### Table of Contents

from country to country and many countries also impose product standards, packaging requirements, labeling requirements and import restrictions on devices.

In the United States, IVDs are regulated by the FDA as medical devices. Medical devices are classified into one of three classes on the
basis of the controls deemed by the FDA to be necessary to reasonably ensure their safety and effectiveness. Class I devices are subject to general controls, including labeling, premarket notification and adherence to FDAs quality system
regulations, which are device-specific good manufacturing practices. Class II devices are subject to general controls and special controls, including performance standards and postmarket surveillance. Class III devices are subject to most of the
previously identified requirements as well as to premarket approval. Class I devices are exempt from premarket submissions to the FDA; most Class II devices require the submission of a 510(k) premarket notification to the FDA; and Class III devices
require submission of a premarket approval application, or PMA. Most in vitro diagnostic kits are regulated as Class I or Class II devices and are either exempt from premarket notification or require a 510(k) submission.

A 510(k) notification must demonstrate that a medical device is substantially equivalent to another legally marketed device, termed a
predicate device, that is legally marketed in the United States and for which a PMA was not required. A device is substantially equivalent to a predicate device if it has the same intended use and technological characteristics as the
predicate, or has the same intended use but different technological characteristics, where the information submitted to the FDA does not raise new questions of safety and effectiveness and demonstrates that the device is at least as safe and
effective as the legally marketed device. Most 510(k)s do not require clinical data for clearance, but a minority will. The FDA is supposed to issue a decision letter within 90 days of receipt of the 510(k) if it has no additional questions or send
a first action letter requesting additional information within 75 days. Requests for additional data, including clinical data, will increase the time necessary to review the notice. If the FDA does not agree that the new device is substantially
equivalent to the predicate device, the new medical device is automatically classified as a Class III device for which a PMA will be required. However, the sponsor may petition the FDA to make a risk-based determination that the device does not pose
the type of risk associated with Class III devices and down-classify the device to Class I or Class II.

Class III devices,
such as our HC2 HPV test, require the submission and approval of a PMA prior to product sale. The PMA process is more complex, costly and time consuming than the 510(k) process. A PMA must be supported by more detailed and comprehensive scientific
evidence, including clinical data, to demonstrate the safety and efficacy of the medical device for its intended purpose. If the device is determined to present a significant risk, the sponsor may not begin a clinical trial until it
submits an investigational device exemption, or IDE, to the FDA and obtains approval from the FDA to begin the trial. After the PMA is submitted, the FDA has 45 days to make a threshold determination that the PMA is sufficiently complete to permit a
substantive review. If the PMA is complete, the FDA will file the PMA. The FDA is subject to a performance goal review time for a PMA of 180 days from the date of filing, although in practice this review time is longer. Questions from the FDA,
requests for additional data and referrals to advisory committees may delay the process considerably. The total process may take several years, and the FDA may also request additional clinical data as a condition of approval or after the PMA is
approved. Product changes after approval typically require a supplemental submission with FDA review cycles ranging from 30 to 180 days.

Any products manufactured or distributed by us pursuant to FDA clearances or approvals are subject to pervasive and continuing regulation by the FDA, including record keeping requirements, reporting of
adverse experiences with the use of the device and restrictions on the advertising and promotion of our products. Device manufacturers are required to register their establishments and list their devices with the FDA and are subject to periodic
inspections by the FDA and certain state agencies. Noncompliance with applicable FDA requirements can result in, among other things, warning letters, fines, injunctions, civil penalties, recalls or seizures of products, total or partial suspension
of production, refusal of the FDA grant 510(k) or PMA approval for devices, withdrawal of 510(k) clearances and/or PMA approvals and criminal prosecution.

##### Table of Contents

Some of our test kits are sold for research use only in the United States. We do not promote
these tests for clinical diagnostic use and they are labeled For Research Use Only or RUO, as permitted by FDA regulations.

Receipt and maintenance of regulatory authorization to market and sell our products is vital to our future success. In addition to seeking regulatory authorizations for our own products, we work with
other companies to seek regulatory clearance or approval for use of their specimen collection products to provide the specimens necessary to perform our diagnostic tests. The time, money and resources required for new product clearances or approvals
by the FDA and foreign government authorities is unpredictable and the necessary approvals or clearances may not be granted on a timely basis or at all. Delays or a failure to receive such approvals or clearances could have a material adverse effect
on our business, financial condition and results of operations.

Organizational Structure

QIAGEN N.V. is the holding company for more than 50 consolidated subsidiaries, the majority of which have the primary function of the
distribution of our products and services on a regional basis. Certain subsidiaries also have research and development or production activities. A listing of our significant subsidiaries, all of which are wholly-owned, and their jurisdiction of
incorporation, is included in Exhibit 8.1 to this Annual Report.

Description of Property

Our production and manufacturing facilities for consumables products are located in Germany, the United States and China. Our instrument
production facilities are located in Switzerland and Australia. Over the last several years, we have made investments in automated and interchangeable production equipment to increase our production capacity and improve efficiency. Our production
and manufacturing operations are highly integrated and benefit from sophisticated inventory control. Our production management personnel are highly qualified and many have advanced degrees in engineering, business and science. We have also installed
and continue to expand production-planning systems that are included in our integrated information and control system based on the business software package SAP R/3 from SAP AG. Worldwide, we use SAP software to integrate our material operating
subsidiaries. Capital expenditures for property, plant and equipment totaled $52.2 million, $39.4 million and $34.5 million for the years ended December 31, 2009, 2008 and 2007, respectively.

We have an established quality system, including standard manufacturing and documentation procedures, intended to ensure that products are
produced and tested in accordance with the FDAs Quality System Regulations, which imposes current Good Manufacturing Practice (cGMP) requirements. For cGMP production, special areas were built in our facilities in Hilden, Germany, and
Germantown and Gaithersburg, Maryland. These facilities operate in accordance with cGMP requirements.

The consumable products
manufactured at QIAGEN GmbH and QIAGEN Hamburg GmbH, both in Germany, and QIAGEN Sciences, Inc. and QIAGEN Gaithersburg, Inc., both in Maryland, are produced under ISO 9001: 2000, ISO 13485:2003 for Medical Devices, and ISO 13485:2003
CMDCAS, and the EC Directive 98/79/EC for medical devices. QIAGEN Instruments AG in Switzerland, which produces the majority of our instrumentation product line, is also ISO 9001: 2000 and 13485:2003 certified. Our certifications form
part of our ongoing commitment to provide our customers high quality, state-of-the-art sample and assay technologies and to the development of our Total Quality Management system.

Our facilities in Hilden, Germany currently occupy a total of approximately 509,000 square feet, some of which is leased pursuant to
separate contracts, the last of which expires in 2018. In two separate transactions between July 1997 and February 1998, we purchased a parcel of land directly adjacent to our existing German facilities, measuring approximately 549,000 square feet.
During 2003, we completed a 115,000 square foot production facility and a 149,000 square foot administration building on this land. During 2005, we purchased our leased cGMP production facilities in Germany and began the planning for a new logistics
center in Hilden.

##### Table of Contents

Construction on the facility began in August 2006 and was completed in 2007. The logistics center comprises approximately 61,000 square feet and cost approximately EUR 9.0 million
(approximately $13.1 million).

Our production capacity is increased through our manufacturing and research facilities in the
United States. QIAGEN Sciences, Inc. owns a 24-acre site in Germantown, Maryland. The 200,000 square foot Germantown facility consists of several buildings in a campus-like arrangement and is intended to accommodate over 300 employees. There is room
for future expansion of up to 400,000 square feet of additional facility space. We lease a facility in Gaithersburg, Maryland, comprising a total of 140,000 square feet for manufacturing, warehousing, distribution and research operations.

In January 2009, we purchased land adjacent to our facility in Hilden, Germany for EUR 2.5 million (approximately $3.2
million) and in August 2009 began construction to further expand our facilities for research and development and production space. In addition, we are planning for expansion at our Germantown, Maryland facility for research, production and
administrative space, construction on which is expected to begin in June 2010. These expansion projects are expected to continue into 2012 at an estimated total cost of approximately $93.9 million. We anticipate that we will be able to fund
such expansions with cash generated by our operating activities.

Other subsidiaries throughout the world lease smaller
amounts of space. Our corporate headquarters are located in leased office space in Venlo, The Netherlands.

We believe that
our existing and planned production and distribution facilities can support our anticipated production needs for the next 36 months. Our production and manufacturing operations are subject to various federal, state, and local laws and regulations
including environmental regulations. We believe we do not have any material issues relating to these laws and regulations.

Results of Operations

Overview

We
believe, based on the nature of our products and technologies and our United States and European market shares, as supported by independent market studies, that we are the worlds leading provider of innovative sample and assay technologies and
products. Sample technologies are used to isolate DNA, RNA and proteins from any biological sample, such as blood or tissue. Assay technologies are then used to make isolated biomolecules, such as the DNA of a specific virus, visible for subsequent
analysis. Our products are considered benchmark standards in areas such as pre-analytical sample preparation and assay solutions in molecular diagnostics, research for life sciences, and applied testing.

We sell our products to molecular diagnostics laboratories, academic researchers, pharmaceutical and biotechnology companies, and applied
testing customers for purposes such as forensics, animal or food testing, and pharmaceutical process control. These products enable our customers to efficiently pursue their research and commercial goals that require the use of nucleic acids. We
market our products in more than 40 countries throughout the world. We have established subsidiaries in the markets that we believe have the greatest sales potential, including countries throughout Europe, Asia, the Americas and Australia. We also
have specialized independent distributors and importers. We employ more than 3,400 people in approximately 30 locations worldwide.

Since 2005, we have had a compound annual growth rate of approximately 21% in net sales and 23% in net income based on reported U.S. GAAP results. We have funded our growth through internally generated funds, debt, and private and public
sales of equity securities. In recent years, we have made a number of strategic acquisitions and disposals expanding and focusing our technology and product offerings. These transactions include:



| |  |  | In December 2009, we acquired SABiosciences Corporation, located in Frederick, Maryland. SABiosciences holds a leading position in the design and
commercialization of disease- and pathway-focused real-time PCR-based assay panels (PCR Arrays), which are widely utilized in biomedical research and in the development of future drugs and diagnostics.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | In July 2007, we completed our acquisition of eGene, Inc., an early-stage company located in Irvine, California that has developed and is
commercializing a patented sample separation and analysis technology based on capillary electrophoresis.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In
2009, on a consolidated basis, operating income increased to $180.2 million compared to $145.7 million in 2008. Our operating income was impacted by growth in consumables and instrument product sales, which experienced growth of 10% and 37% in
2009 as compared to 36% and 51% in 2008, respectively. Our financial results include the contributions of our recent acquisitions from the date of their acquisition, as well as the costs related to the acquisitions and integrations. Our results also
reflect the benefits of our previous restructuring efforts, which have contributed to improved profitability as we continue to manage our operating costs.

In 2008, on a consolidated basis, operating income increased to $145.7 million compared to $83.1 million in 2007. In 2007 we recorded a $25.9 million charge for in-process research and development
primarily in connection with our acquisition of Digene.

Reportable segments are based on the geographic locations of our
subsidiaries. Our reportable segments include our production, manufacturing and sales facilities located throughout the world. In addition, the Corporate segment includes our holding company located in The Netherlands, two subsidiaries located in
Germany and one in Australia which operate only in a corporate support function. The reportable segments derive revenues from our entire product and service offerings. Our Luxembourg subsidiaries, QIAGEN Finance (Luxembourg) S.A., or QIAGEN Finance,
and QIAGEN Euro Finance (Luxembourg) S.A., or Euro Finance, which were established as financing vehicles for the issuance of convertible debt, are not consolidated.

The following table sets forth operating income by segment for the years ended December 31, 2009, 2008 and 2007. Further segment information can be found in Note 19 to the accompanying financial

In 2009, operating income in the Americas increased compared to the same period in 2008,
primarily due to increased sales. Operating income increased in the Americas in 2008 as compared to 2007 primarily due to the July 2007 acquisitions which contributed for the entire year in 2008 versus a partial year in 2007. Additionally, the third
quarter 2007 includes a charge of $25.9 million for purchased in-process research and development. While sales increased during 2009 and 2008 as a result of acquisitions and organic growth, expenses in the Americas, including the amortization of
acquired intangibles, were also higher following the acquisitions and ongoing integration efforts.

In Germany, operating
income was higher in 2009 and 2008, as compared to 2007, primarily due to increased sales.

The increase in operating income
in Switzerland in 2009 as compared to 2008 is primarily the result of increased sales and higher gross margins which were favorably impacted by leverage of capacity and mix of products. The decrease in operating income in 2008, as compared to 2007,
was primarily due to an increase in research and development expense, partially offset by an increase in instrumentation sales.

The increase in operating income in Asia in 2009 as compared to 2008 is primarily the result of increased sales, primarily in Japan. The net decrease in operating income in our Asia segment in 2008 compared to 2007 is primarily due to an
increase in operating expense in China, as a result of opening our new China sales office, located in Shanghai.

The decrease
in operating income in our All Other segment in 2009 as compared to 2008 is primarily due to the September 2009 acquisition of DxS. The increase in operating income in 2008 as compared to 2007 in our All Other segment is primarily due to the July
2008 acquisition of Corbett.

Fiscal Year Ended December 31, 2009 Compared to 2008

Net Sales

In 2009, net sales increased 13% to $1.0 billion compared to $893.0 million in 2008. The increase in total sales includes organic growth (13%) and sales from our recently acquired businesses (4%), partially offset by the negative
impact of foreign currency exchange rates (3%) and the third quarter divestiture of our subsidiary in Austria (1%). Our 2009 net sales include the results of operations for the full year of Corbett, which was acquired in July 2008, as well as
the acquisitions of DxS Ltd, acquired in September 2009, and SABiosciences, acquired in December 2009.

Net sales are
attributed to countries based on the location of the subsidiary recording the sale. In 2009, net sales in Asia increased by 39%, primarily driven by China, Japan and Singapore, net sales in Germany increased by 24%, net sales in the Americas
increased by 9% and net sales in all other countries increased by 5%, which includes the results of Corbett and DxS. The increase in sales in each of these regions was the result of an increase in sales of our sample and assay technologies, which
represented approximately 86% of total sales, and instruments products, which represented approximately 14% of total sales. Sales of sample and assay technologies, which include consumables and instrumentation, experienced growth rates of 10% and
37%, respectively, in 2009, as compared to 2008. The uncertainties of the current global financial crisis represent a risk for the Company, and while we expect continued growth in our consumables and instrumentation businesses, such future growth
may be lower than our historical growth and future growth could be adversely effected.

A significant portion of our revenues
is denominated in euros and currencies other than the United States dollar. Changes in exchange rates can affect the growth rate of net sales, potentially to a significant degree. When calculated by translating the local currency, actual results in
the current period using the average exchange rates from the previous years respective period instead of the current period, net sales were negatively impacted by $28.8 million of currency effects for the year ended December 31, 2009, as
compared to 2008.

##### Table of Contents

We regularly introduce new products in order to extend the life of our existing product
lines as well as to address new market opportunities. In 2009, we launched 79 new products in the area of sample & assay technologies including the PAXgene Blood miRNA kit for use in cancer, biomarker and miRNA research and the QIAamp
Circulating Nucleic Acid kit for sample preparation in prenatal or other circulating nucleic acid research. In addition, QIAGEN launched a number of assay technologies including two multiplexed, PCR-based CE-marked digene HPV Genotyping Tests, a
next generation CE marked mutation profiling KRAS test, as well as a BRAF test for use in cancer treatments and a test for epigenetic methylation analysis based on pyrosequencing technology.

Gross Profit

Gross profit was $667.1 million, or 66% of net sales, in the year ended December 31, 2009 as compared to $599.7 million, or 67% of net sales, in 2008. The absolute dollar increase in 2009 compared to 2008 is attributable to the
increase in net sales. Our sample and assay products have a higher gross margin than our instrumentation products, and fluctuations in the sales levels of these products can result in fluctuations in our gross margin during a period when compared to
the gross margin of another period.

Amortization expense related to developed technology and patent and license rights, which
have been acquired in a business combination, is included in cost of sales. The amortization expense on acquisition-related intangibles within cost of sales increased to $53.6 million in 2009 as compared to $48.7 million in 2008. The increase in
amortization expense is the result of an increase in intangibles acquired in our recent business combinations. We expect that our acquisition-related intangible amortization will continue to increase as a result of our acquisitions.

In addition, during 2009 and 2008 a total of $7.4 million and $1.4 million, respectively, was expensed to acquisition-related cost of sales
related to the write-off of inventories made obsolete following an acquisition as well as to the write-up of acquired inventory to fair market value as a result of business combinations. In accordance with purchase accounting rules, acquired
inventory was written-up to fair market value and subsequently expensed as the inventory was sold. Additionally, in 2009, we recognized a charge of $2.5 million to cost of sales related to the impairment of developed technology, which was triggered
by the acquisition of DxS and the discontinuation of certain products.

Research and Development

Research and development expenses increased by 11% to $107.9 million (11% of net sales) in 2009 compared to $97.3 million (11% of net sales)
in the same period of 2008. Our business combinations, along with the acquisition of new technologies, have resulted in an increase in our research and development costs. As we continue to discover, develop and acquire new products and technologies,
we will incur additional expense related to research and development facilities, licenses and employees engaged in our research and development efforts. Additionally, our research and development costs are expected to increase as a result of seeking
regulatory approvals, including U.S. FDA Pre-Market Approval (PMA), U.S. FDA 510(k) and EU CE approval of certain assays or instruments. The increase in research and development expense was partially offset by $2.8 million of currency impact in 2009
calculated by translating the local currency actual results in the current period using the average exchange rates from the previous years respective period instead of the current period. We have a strong commitment to research and development
and expect to continue to make investments in our research and development efforts. Accordingly, our research and development expenses will continue to increase, perhaps significantly.

Sales and Marketing

Sales and marketing expenses increased by 8% to $244.8 million (24% of net sales) in 2009 from $227.4 million (25% of net sales) in 2008. Sales and marketing expenses are primarily associated with personnel, commissions, advertising, trade
shows, publications, freight and logistics expenses and other promotional

##### Table of Contents

expenses. The increase in sales and marketing expenses in 2009 as compared to 2008, is primarily due to our 2009 acquisitions, as well as the acquisition of Corbett which occurred in July of
2008, and thus is only included for part of 2008. In addition, the sales and marketing expenses include the costs of maintaining separate sales organizations addressing customers in industrial and academic research, applied testing and molecular
diagnostics. The increase in sales and marketing expense was partially offset by $6.9 million of currency impact in 2009 when calculated by translating the local currency actual results in the current period using the average exchange rates from the
previous years respective period instead of the current period. We anticipate that sales and marketing costs will continue to increase along with new product introductions and continued growth in sales of our products, but we expect sales and
marketing costs will, for the most part, grow at a slower rate than our overall revenue growth.

General and
Administrative, Integration and Other

General and administrative, business integration, restructuring and related costs
increased by 2% to $115.9 million (11% of net sales) in 2009 from $113.9 million (13% of net sales) in 2008. The increase in these expenses in 2009 is partly the result of general and administrative expenses related to our new acquired businesses.
Additionally, during 2009, an impairment loss of $1.6 million of goodwill was recognized in connection with our acquisition of DxS Ltd. in September 2009. We have continued to incur integration costs for businesses acquired and such costs totaled
approximately $21.5 million in 2009, as compared to $30.9 million in 2008. Included in these costs are $7.5 million in 2009 and $8.1 million in 2008 for legal costs related to litigation assumed in connection with the acquisitions of Digene and
Corbett. In connection with the integration of the acquired companies, we aim to improve efficiency in general and administrative operations. Additionally, when calculated by translating the local currency actual results in the current period using
the average exchange rates from the previous years respective period instead of the current period, general and administrative, integration and related costs decreased by $2.1 million due to currency impact in 2009, as compared to 2008.

In October 2009, we started the closure of our facilities and relocation of our activities in Brisbane and Sydney to other
locations of the Company, primarily to QIAGEN Instruments AG in Switzerland. These restructurings follow the acquisition of Corbett in 2008 and consolidate our instrument manufacturing activities. The closure and relocation are expected to be
completed in the second quarter of 2010 at a total pre-tax cost of approximately $4.0 million to $5.0 million.

As we further
integrate the acquired companies, we expect to continue to incur additional business integration costs. We believe that over time the results of the integration activities will continue to result in a decrease in our general and administrative
expenses as a percentage of sales.

Acquisition-Related Intangible Amortization

Amortization expense related to developed technology and patent and license rights, which have been acquired in a business combination, is
included in cost of sales. Amortization of trademarks, customer base and non-compete agreements, which have been acquired in a business combination, is recorded in operating expense under the caption acquisition-related intangible
amortization. Amortization expenses of intangible assets not acquired in a business combination are recorded within either cost of sales, research and development or sales and marketing line items based on the use of the asset.

During 2009, the amortization expense on acquisition-related intangibles within operating expense increased to $18.2 million compared to
$14.4 million in 2008. The increase in expense is the result of an increase in amortized intangibles acquired in our recent business combinations. We expect that our acquisition-related intangible amortization will continue to increase as a result
of our acquisitions.

Purchased In-Process Research and Development

Purchased in-process research and development costs represent the value assigned to research and development projects which were commenced
but not yet completed at the date of acquisition, whose

##### Table of Contents

technological feasibility has not been established and which have no alternative future use in research and development activities or otherwise. In connection with our 2009 acquisitions, we have
capitalized $3.1 million of purchased in-process research and development as an indefinite lived intangible asset. Prior to January 1, 2009, in-process research and development was expensed. In connection with our 2008 acquisition of Corbett,
we recorded charges of $985,000 for purchased in-process research and development. Beginning in 2009, purchased in-process research and development costs are capitalized and no longer expensed. For further information, see Note 4 of the Notes to
Consolidated Financial Statements included in Item 18.

Other Income (Expense)

Other expense was $7.9 million in 2009, as compared to other expense of $26.4 million in 2008. This decrease in expense was mainly due to
lower interest expense, a gain from the sale of a cost-method investment and the impairment of a cost-method investment. During the fourth quarter of 2009, we sold our investment in a privately held company and realized a gain of $10.5 million.
During the third quarter of 2008, in connection with the acquisition of Corbett, we recorded a $4.0 million impairment of a cost-method investment based on an assessment of the recoverability of the investment amount. Following the acquisition of
Corbett, we anticipated a change in our purchasing pattern of the investees products, which was expected to negatively impact the forecasted financial condition of the investee. Accordingly, we believe the known impact to the investees
financial condition, absent other evidence indicating a realizable value of the investment, indicated that the recoverability of the asset through future cash flows was not considered likely enough to support the carrying value.

For the year ended December 31, 2009, interest income decreased to $3.5 million from $9.5 million in 2008. The decrease in interest
income was primarily due to a decline in interest rates.

Interest expense decreased to $29.6 million in 2009 compared to
$37.5 million in 2008. Interest costs primarily relate to our long-term debt discussed in Note 14 in the accompanying notes to the consolidated financial statements. The decrease in interest expense is primarily due to a decrease in the interest
expense on our term loan as a result of a decreasing LIBOR rate as well as a $25.0 million decreased debt balance.

Provision for Income Taxes

Our provision for income taxes is based upon the estimated annual effective tax
rates. Fluctuations in the distribution of pre-tax income among our operating subsidiaries can lead to fluctuations of the effective tax rate in the consolidated financial statements. Our operating subsidiaries are exposed to effective tax rates
ranging from zero up to approximately 42%.

In 2009 and 2008, our effective tax rates were 20% and 25%, respectively. In
2009, the mix of earnings was more heavily weighted in the lower tax rate jurisdictions versus higher tax rate jurisdictions in 2008. Additionally, a number of discrete events occurred during 2009 which resulted in favorable tax benefits
being recognized in the income statement. These discrete events include but are not limited to post-merger internal restructuring initiated to better align our businesses which led to favorable tax benefits; sale of our Austrian business and a
cost-method investment on almost an entirely tax free basis; tax planning and reductions in certain purchase-accounting-related deferred tax liabilities due to tax rate changes and step-up in tax basis. Certain of these items are non-recurring in
nature and will not have a future tax rate impact.

Fiscal Year Ended December 31, 2008 Compared to 2007

Net Sales

In 2008, net sales increased 37% to $893.0 million compared to $649.8 million in 2007. Our 2008 net sales include the results of operations of Corbett, which was acquired in July 2008, as well as Digene and eGene,

which were acquired in the third quarter of 2007. The increase in total sales includes organic growth (13%), sales from our recently acquired businesses (22%), and the impact of foreign exchange
rates (2%). Net sales are attributed to countries based on the location of the subsidiary recording the sale. In 2008, net sales in Germany increased by 25%, net sales in Asia increased by 25%, primarily driven by Singapore, China, and Korea, net
sales in the Americas increased by 46% and net sales in all other countries increased by 38%, which includes the results of Corbett. The increase in sales in each of these regions was the result of an increase in sales of our sample and assay
technologies, which represented approximately 88% of total sales, and instrumentation products, which represented approximately 11% of total sales. Sales of sample and assay technologies which include consumables and instrumentation experienced
growth rates of 36% and 51%, respectively, in 2008 as compared to 2007.

We regularly introduce new products in order to
extend the life of our existing product lines as well as to address new market opportunities. In 2008, we launched more than 80 new products in the area of sample & assay technologies, including the QIAxcel for fully automated capillary
electrophoresis to separate and analyze DNA, RNA and proteins, the QIAsymphonySP, the first system of a novel modular processing platform which can be integrated to automate entire sample and assay technology-related workflows and the EZ1 Advanced,
the next generation of our successful EZ1 for the fully automated low throughput sample preparation with prefilled cartridges. In addition, we launched a number of assay technologies including two tests for the applied testing markets to detect
bovine viral diarrhea virus (BVD) in cattle and Taylorella equigenitalis in horses, a series of products for analyzing genetic differences and micro RNA (miRNA) analysis as well as a CE-marked test for the detection and quantification of Malaria (P.
falciparum, P. vivax, P. ovale and P. malariae), the next generation of multiplex detection of respiratory viral targets (ResPlex II Panel v 2.0) and a molecular diagnostic assay in the EU to type the HLA-B*5701 allele, a genetic variation in the
Human Leucocyte Antigen (HLA) system, causing adverse reactions in AIDS patients.

A significant portion of our revenues is
denominated in euros and currencies other than the United States dollar. Changes in exchange rates can affect the growth rate of net sales, potentially to a significant degree. For the year ended December 31, 2008, as compared to the same
period in 2007, using the 2007 foreign exchange rates for both periods, net sales would have increased approximately by 35% as compared to the reported increases of 37%.

Gross Profit

Gross profit was $599.7 million, or 67% of net sales, in the
year ended December 31, 2008 as compared to $433.5 million, or 67% of net sales, in 2007. The absolute dollar increase in 2008 compared to 2007 is attributable to the increase in net sales. Our sample and assay products have a higher gross
margin than our instrumentation products, and fluctuations in the sales levels of these products can result in fluctuations in our gross margin during a quarter when compared to the gross margin of another quarter. During 2008 and 2007, sample and
assay product sales represented approximately 88% and 89% of our total sales, respectively. The gross margin in 2008 as compared to 2007 reflects an increase in sample and assay sales at a more favorable margin, offset by an increase in amortization
of acquisition-related intangible assets.

Amortization expense related to developed technology and patent and license rights,
which have been acquired in a business combination, is included in cost of sales. The amortization expense on acquisition-related intangibles within cost of sales increased to $48.7 million in 2008 as compared to $23.6 million in 2007. The increase
in amortization expense is the result of an increase in intangibles acquired in our recent business combinations, namely Corbett and Digene which were acquired in July 2008 and 2007, respectively.

In addition, during 2008, a total of $1.4 million was expensed to acquisition-related cost of sales related to the write-up of acquired
inventory to fair market value as a result of the 2008 business combinations. In accordance with purchase accounting rules, acquired inventory was written-up to fair market value and subsequently expensed as the inventory was sold. During 2007, a
total of $2.8 million was expensed to

acquisition-related cost of sales and included approximately $300,000 of inventory, which was written off as a result of the Digene and eGene acquisitions as well as $2.5 million in cost related
to the write-up of acquired inventory to fair market value as a result of the 2007 business combinations.

Research and
Development

Research and development expenses increased by 50% to $97.3 million (11% of net sales) in 2008 compared to
$64.9 million (10% of net sales) in the same period of 2007. Using identical foreign exchange rates for both years, research and development expenses increased approximately 44%. Our 2007 and 2008 acquisitions, along with the acquisition of new
technologies, have resulted in an increase in our research and development costs. As we continue to discover, develop and acquire new products and technologies, we will incur additional expense related to research and development facilities,
licenses and employees engaged in our research and development efforts. Additionally, our research and development costs are expected to increase as a result of seeking regulatory approvals, including U.S. FDA Pre-Market Approval (PMA), U.S. FDA
510(k) and EU CE approval of certain assays or instruments.

Sales and Marketing

Sales and marketing expenses increased by 38% to $227.4 million (25% of net sales) in 2008 from $164.7 million (25% of net sales) in 2007.
Using identical foreign exchange rates for both years, sales and marketing expenses increased 35%. Sales and marketing expenses are primarily associated with personnel, commissions, advertising, trade shows, publications, freight and logistics
expenses and other promotional expenses. The increase in sales and marketing expenses in 2008 as compared to 2007 is primarily due to our acquisitions of Corbett and Digene in July of 2008 and 2007, respectively, through which we acquired over 200
sales and marketing personnel. In addition, the sales and marketing expenses include the costs of maintaining separate sales organizations addressing customers in industrial and academic research, applied testing and molecular diagnostics. We
anticipate that sales and marketing costs will continue to increase along with new product introductions and continued growth in sales of our products.

General and Administrative, Integration and Other Costs

General and
administrative, business integration, restructuring and related costs increased by 31% to $113.9 million (13% of net sales) in 2008 from $87.2 million (13% of net sales) in 2007. Using identical foreign exchange rates for both years, these expenses
increased by approximately 28%. The increase in these expenses in 2008 is partly the result of general and administrative expenses related to our new businesses acquired in 2008, which have expanded our presence in Australia, as well as the full
years expense from our 2007 acquisitions. Further, we have continued to incur integration costs for businesses acquired in 2007 as well as for the new businesses acquired in 2008. General and administrative expenses primarily represent the
costs required to support our administrative infrastructure which generally has continued to expand along with our growth. Included in these costs are $8.1 million in 2008 and $7.2 million in 2007 for legal costs related to litigation assumed in
connection with the acquisitions of Digene and Corbett. In connection with the integration of the acquired companies, we aim to improve efficiency in general and administrative operations.

Acquisition-Related Intangible Amortization

Amortization expense related to developed technology and patent and license rights, which have been acquired in a business combination, is included in cost of sales. Amortization of trademarks, customer
base and non-compete agreements, which have been acquired in a business combination, is recorded in operating expense under the caption acquisition-related intangible amortization. Amortization expenses of intangible assets not acquired
in a business combination are recorded within either cost of sales, research and development or sales and marketing line items based on the use of the asset.

##### Table of Contents

During 2008, the amortization expense on acquisition-related intangibles within operating
expense increased to $14.4 million compared to $7.7 million in 2007. The increase in expense is the result of an increase in amortized intangibles acquired in our recent business combinations.

Purchased In-Process Research and Development

Purchased in-process research and development costs represent the value assigned to research and development projects which were commenced but not yet completed at the date of acquisition, technological
feasibility for these projects has not been established and they have no alternative future use in research and development activities or otherwise. In connection with our 2008 acquisition of Corbett, we recorded charges of $985,000 for purchased
in-process research and development. In connection with acquisitions in 2007, we recorded a charge of $25.9 million for purchased in-process research and development which included $900,000 related to eGene and $25.0 million related to Digene. For
further information on the purchased in-process research and development, see Note 4 of the Notes to Consolidated Financial Statements included in Item 18.

Other Income (Expense)

Other expense was $26.4 million in 2008, as
compared to other expense of $7.4 million in 2007. This increase in expense was mainly due to higher interest expense, lower interest income and the impairment of a cost-method investment. During the third quarter of 2008, in connection with the
acquisition of Corbett, we recorded a $4.0 million impairment of a cost-method investment based on an assessment of the recoverability of the investment amount. Following the acquisition of Corbett, we anticipated a change in our purchasing pattern
of the investees products, which is expected to negatively impact the forecasted financial condition of the investee. Accordingly, we believe the known impact to the investees financial condition, absent other evidence indicating a
realizable value of the investment, indicated that the recoverability of the asset through future cash flows was not considered likely enough to support the carrying value.

For the year ended December 31, 2008, interest income decreased to $9.5 million from $19.5 million in 2007. The decrease in interest
income was due to a decrease in the amount of investments along with a decline in interest rates.

Interest expense increased
to $37.5 million in 2008 compared to $31.5 million in 2007. Interest costs primarily relate to the $500.0 million term loan obtained in July 2007 in connection with the Digene acquisition and our long-term borrowings from QIAGEN Finance and Euro
Finance. The increase in interest expense in 2008 as compared to 2007 is primarily due to the interest expense on the new term loan obtained in July 2007 which is tied to LIBOR plus a margin.

Provision for Income Taxes

Our provision for income taxes is based upon the estimated annual effective tax rates. Fluctuations in the distribution of pre-tax income among our operating subsidiaries can lead to fluctuations of the
effective tax rate in the consolidated financial statements. Our operating subsidiaries are exposed to effective tax rates ranging from zero up to approximately 42%.

In 2008 and 2007, our effective tax rates were 25% and 34%, respectively. The effective tax rates during 2008 and 2007 are impacted as a result of non-recurring acquisition-related charges which
were recorded without any related tax benefit. In 2008, an increasing portion of our pre-tax income is attributable to subsidiaries with lower effective tax rates as compared to 2007. In 2008, the German tax rate decreased to 30% as compared to
39% in 2007. Further, the effective tax rates during 2007 are impacted as a result of the $25.9 million purchased in-process research and development charge which was recorded without any related tax benefit.

Foreign Currency

QIAGEN N.V.s functional currency is the U.S. dollar and our subsidiaries functional currencies are the local currency of the respective countries in which they are headquartered. All amounts
in the financial statements of entities whose functional currency is not the U.S. dollar are translated into U.S. dollar equivalents at exchange rates as follows: (1) assets and liabilities at period-end rates, (2) income statement
accounts at average exchange rates for the period, and (3) components of shareholders equity at historical rates. Translation gains or losses are recorded in shareholders equity, and transaction gains and losses are reflected in net
income. The net gain (loss) on foreign currency transactions in 2009, 2008 and 2007 was $5.6 million, ($0.2) million and $2.0 million, respectively, and is included in other income (expense), net.

Derivatives and Hedging

In the ordinary course of business, we use derivative instruments, including swaps, forwards and/or options, to manage potential losses from foreign currency exposures and variable rate debt. The principal objective of such derivative
instruments is to minimize the risks and/or costs associated with global financial and operating activities. We do not utilize derivative or other financial instruments for trading or other speculative purposes. All derivatives are recognized as
either assets or liabilities in the balance sheet and are measured at fair value with any change in fair value recognized in earnings in the period of change, unless the derivative qualifies as an effective hedge that offsets certain exposures. In
determining fair value, we consider both the counterparty credit risk and our own creditworthiness. To determine our own credit risk we estimated our own credit rating by benchmarking the price of our outstanding debt to publicly-available
comparable data from rated companies. Using the estimated rating, we quantified our credit risk by reference to publicly-traded debt with a corresponding rating.

Foreign Currency Derivatives.As a globally active enterprise, we are subject to risks associated with fluctuations in foreign currencies in our ordinary operations.
This includes foreign currency-denominated receivables, payables, debt, and other balance sheet positions. We manage our balance sheet exposure on a group-wide basis primarily using foreign exchange forward contracts.

Interest Rate Derivatives.We use interest rate derivative contracts on certain borrowing transactions
to hedge fluctuating interest rates. We have entered into interest rate swaps in which we agree to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional
principal amount.

We make use of economic hedges, i.e. derivatives that do not have a formally designated hedging
relationship as well as accounting hedges. All derivatives that qualify for hedge accounting are cash-flow hedges. Further details of our derivative and hedging activities can be found in Note 6 to the accompanying
consolidated financial statements.

Liquidity and Capital Resources

To date, we have funded our business primarily through internally generated funds, debt and the private and public sales of equity. Our
primary use of cash has been to support continuing operations and our capital expenditure requirements including acquisitions. As of December 31, 2009 and 2008, we had cash and cash equivalents of $825.6 million and $333.3 million,
respectively. We also had short-term investments of $40.0 million at December 31, 2009. Cash and cash equivalents are primarily held in U.S. dollars, euros and Australian dollars, other than those cash balances maintained in the local currency
of subsidiaries to meet local working capital needs. At December 31, 2009, cash and cash equivalents had increased by $492.2 million from December 31, 2008 primarily due to cash provided by operating activities of $217.0 million and
financing activities of $629.2 million, offset by cash used in investing activities of $341.7 million. As of December 31, 2009 and 2008, we had working capital of $957.9 million and $441.2 million, respectively.

Operating Activities.    For the years ended
December 31, 2009 and 2008, we generated net cash from operating activities of $217.0 million and $173.0 million, respectively. Cash provided by operating activities increased in 2009 compared to 2008 primarily due to increases in net income,
depreciation and amortization, and accrued and other liabilities, partially offset by increases in accounts receivable and inventories. The increase in net income and accounts receivable is primarily attributable to our 2009 sales growth, while the
increase in depreciation and amortization is primarily due to our new acquisitions. The increase in accrued and other liabilities reflects higher accruals as a result of our growth, such as accrued payroll and royalties. The increase in inventories
in 2009 primarily reflects our new product introductions along with increases related to safety stock in order to minimize potential challenges in abilities to supply. Because we rely heavily on cash generated from operating activities to fund our
business, a decrease in demand for our products, longer collection cycles or significant technological advances of competitors would have a negative impact on our liquidity.

Investing Activities.Approximately $341.7 million of cash was used in investing activities during
2009, compared to $210.5 million during 2008. Investing activities during 2009 consisted principally of cash paid for purchases of property and equipment and intangible assets as well as cash paid for acquisitions. During 2009, cash paid for
acquisitions, net of cash acquired totaled $234.7 million and includes cash paid for acquisitions made in 2009 as well as milestone payments from previous acquisitions. In September 2009, we acquired DxS Ltd., a privately-held developer and
manufacturer of companion diagnostic products headquartered in Manchester, United Kingdom, for an upfront purchase price of $94.5 million in cash and potential future milestone payments. Additionally, in August 2009, we acquired Explera s.r.l., a
leading supplier in molecular diagnostics and personalized medicine in Italy. In December 2009, we acquired SABiosciences, located in Frederick, Maryland for $97.6 million in cash subject to customary adjustment. Investing activities during 2008
consisted principally of purchases of property and equipment, intangibles and cash paid for acquisitions as well as a loan to Dx Assay Pte Ltd, our new joint venture in Singapore, partially offset by the sale of marketable securities.

In connection with certain acquisitions, we could be required to make additional contingent cash payments totaling up to $106.2 million
based on the achievement of certain revenue and operating results milestones as follows: $18.6 million in 2010, $16.5 million in 2011, $16.2 million in 2012 and $54.9 million payable in any 12 month period from now until 2014 if certain criteria are
met. Of the $106.2 million total contingent obligation, approximately $40.8 million is accrued as of December 31, 2009.

In January 2009, we purchased land adjacent to our facility in Hilden, Germany for EUR 2.5 million (approximately $3.2 million) and in August 2009 began the construction to further expand the German facilities for research and
development and production space. In addition, we are planning for expansions at our Germantown, Maryland facility for production and administrative space, construction on which is expected to begin in June 2010. These expansion projects are
expected to continue into 2012 at an estimated total cost of approximately $93.9 million. We anticipate that we will be able to fund such expansions with cash generated by our operating activities.

Financing Activities.    Financing activities provided $629.2 million in cash for the year ended
December 31, 2009, compared to $12.8 million for 2008. Cash provided during 2009 was primarily due to the sale of 31.625 million common shares, including 4.125 million common shares upon exercise of the underwriters
over-allotment option, in September 2009. After deducting the underwriting discounts, commissions and the offering expenses net of tax, the total net proceeds from the offering were $623.6 million. We intend to use the net proceeds of this offering
to fund acquisitions, including our September 2009 acquisition of DxS Ltd. and our December 2009 acquisition of SABiosciences, to strengthen our balance sheet and for general corporate purposes.

We have credit lines totaling $183.7 million at variable interest rates, an insignificant amount of which was utilized as of
December 31, 2009. We also have capital lease obligations, including interest, in the aggregate

amount of $38.9 million, and carry $920.0 million of long-term debt, of which $50.0 million is current as of December 31, 2009.

In July 2007, we signed a Syndicated Multi-Currency Term Loan and Revolving Credit Facilities Agreement with Deutsche Bank AG, Deutsche
Bank Luxembourg S.A., and the lenders named in the syndication agreement. The lenders made available to us an aggregate amount of $750 million in the form of (1) a $500.0 million term loan, (2) a $100.0 million bridge loan, and (3) a
$150.0 million revolving credit facility. Under the agreement, the $500.0 million term loan will mature in July 2012 with an amortization schedule commenced July 2009. The $150.0 million revolving credit facility will also expire in July 2012. The
$100.0 million bridge loan was utilized and repaid within the third quarter of 2007. We used the proceeds of the term loan and the bridge loan to pay the cash component of the Digene acquisition consideration and the fees and expenses of the Digene
offer and the merger. The revolving credit facility is available for general corporate purposes. The interest due on the $500.0 million term loan and the $150.0 million currently undrawn revolving credit facility is tied to the LIBOR benchmark and
therefore variable. A $200.0 million portion of the $500.0 million term loan has been swapped into a fixed interest rate.

We
have notes payable, which are the long-term borrowings of the proceeds from the issuances of $150.0 million senior unsubordinated convertible notes, with a 1.5% coupon due in 2024 through QIAGEN Finance (2004 Notes), and of $300.0 million 3.25%
senior convertible notes (2006 Notes) due in 2026 through Euro Finance. QIAGEN Finance and Euro Finance are unconsolidated subsidiaries, which were established for this purpose. At December 31, 2009, $145.0 million and $300.0 million are
included in long-term debt for the amount of 2004 Notes and 2006 Notes payable to QIAGEN Finance and Euro Finance, respectively. In connection with conversion of $5.0 million of the 2004 Notes, we repaid $5.0 million of the debt to QIAGEN Finance.
The 2004 Notes have an effective rate of 2.14%, are due in July 2011 and are convertible into our common shares at a conversion price of $12.6449, subject to adjustment. The 2006 Notes have an effective rate of 3.91%, are due in November 2012 and
are convertible into our common shares at a conversion price of $20.00, subject to adjustment. QIAGEN N.V. has guaranteed the 2004 and 2006 Notes and has agreements with QIAGEN Finance and Euro Finance to issue shares to the investors in the event
of conversion. These subscription rights, along with the related receivable, are recorded at fair value in the equity of QIAGEN N.V. as paid-in capital. In November 2008, we issued 395,417 common shares upon the exercise of a portion of the
subscription rights in connection with the conversion of $5.0 million of the 2004 Notes.

We expect that cash from financing
activities will continue to be impacted by issuances of our common shares in connection with our equity compensation plans and that the market performance of our stock will impact the timing and volume of the issuances. Additionally, we may make
future acquisitions or investments requiring cash payments or the issuance of additional equity or debt financing.

We believe
that funds from operations, existing cash and cash equivalents, together with the proceeds from our public and private sales of equity, and availability of financing facilities, will be sufficient to fund our planned operations and expansion during
the coming year. However, the global economic downturn may have a greater impact on our business than currently expected, and we may experience a decrease in the sales of our products, which could impact our ability to generate cash. The
availability of debt financing has also been negatively impacted by the global credit crisis. If our future cash flows from operations and other capital resources are not adequate to fund our liquidity needs, we may be required to obtain additional
debt or equity financing or reduce or delay our capital expenditures, acquisitions or research and development projects. If we could not obtain financing on a timely basis or at satisfactory terms, or implement timely reductions in our expenditures,
our business could be adversely affected.

Off-Balance Sheet Arrangements

Other than our arrangements with QIAGEN Finance and Euro Finance as discussed above and in Notes 10, 14 and 18 to the consolidated financial
statements, we did not use special purpose entities and do not have off-balance-sheet financing arrangements as of and during the years ended December 31, 2009, 2008 and 2007.

In addition to the above and pursuant to purchase
agreements for several of our recent acquisitions, we could be required to make additional contingent cash payments totaling up to $106.2 million based on revenue and other milestones in 2010 and beyond.

Liabilities associated with uncertain tax positions, including interest, are currently estimated at $10.8 million and are not included in
the table above as we cannot reasonably estimate when, if ever, an amount would be paid to a government agency. Ultimate settlement of these liabilities is dependent on factors outside of our control, such as examinations by each agency and
expiration of statutes of limitation for assessment of additional taxes.

Critical Accounting Policies, Judgments and Estimates

The preparation of our financial statements in accordance with accounting principles generally accepted in the United States
requires management to make assumptions that affect the reported amounts of assets, liabilities and disclosure of contingencies as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting
period. Critical accounting policies are those that require the most complex or subjective judgments often as a result of the need to make estimates about the effects of matters that are inherently uncertain. Thus, to the extent that actual events
differ from managements estimates and assumptions, there could be a material impact to the financial statements. In applying our critical accounting policies, at times we used accounting estimates that either required us to make assumptions
about matters that were highly uncertain at the time the estimate was made or it is reasonably likely that changes in the accounting estimate may occur from period to period that would have a material impact on the presentation of our results of
operations, financial position or cash flows. Our critical accounting policies are those related to revenue recognition, investments, goodwill and other intangible assets, share-based compensation, income taxes and purchase price allocation. We
reviewed the development, selection, and disclosure of our critical accounting policies and estimates with the Audit Committee of our Supervisory Board.

Revenue Recognition.We recognize revenue when four basic criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or
services have been rendered; (3) the fee is fixed and determinable; and (4) collectability is reasonably assured. Determination of criteria (3) and (4) could require managements judgments regarding the fixed nature of the
fee charged for services rendered and products delivered and the collectability of those fees. Should changes in conditions cause management to determine that

these criteria are not met for certain future transactions, revenue recognized for any reporting period could be adversely affected.

Investments.We have equity investments accounted for under the cost method. We periodically review the
carrying value of these investments for permanent impairment, considering factors such as the most recent stock transactions, book values from the most recent financial statements, and forecasts and expectations of the investee. Estimating the fair
value of these non-marketable equity investments in life science companies is inherently subjective, and if actual events differ from managements assumptions, it could require a write-down of the investment that could materially impact our
financial position and results of operations.

In addition, generally accepted accounting principles require different methods
of accounting for an investment depending on the level of influence that we exert. Assessing the level of influence involves subjective judgments. If managements assumptions with respect to its level of influence differ in future periods and
we therefore have to account for these investments under a method other than the cost method, it could have a material impact to our financial statements.

Goodwill and Other Intangible Assets.We account for acquisitions under the purchase method of accounting, typically resulting in goodwill. We assess goodwill for
impairment at least annually in the absence of an indicator of possible impairment and immediately upon an indicator of possible impairment. If we determine that the fair values of our reporting units are less than the carrying amount of goodwill
recorded, we must recognize an impairment in our financial statements. Due to the numerous variables associated with our judgments and assumptions relating to the valuation of the reporting units and the effects of changes in circumstances affecting
these valuations, both the precision and reliability of the resulting estimates are subject to uncertainty, and as additional information becomes known, we may change our estimate.

At December 31, 2009, goodwill and intangible assets totaled $1.3 billion and $752.3 million, respectively, and were included in the
following segments:



|            |  |          |           |             |   |

|Total       |  | $        | 1,337,064 |             | $ | 752,296
|            |  |          |           |             |   |        

In the fourth quarter of 2009, we performed our annual
impairment assessment of goodwill (using data as of October 1, 2009). In testing for potential impairment, we measured the estimated fair value of our reporting units based upon discounted future operating cash flows using a discount rate
reflecting our estimated average cost of funds. Differences in assumptions used in projecting future operating cash flows and cost of funds could have a significant impact on the determination of impairment amounts. In estimating future cash flows,
we used our internal budgets. Our budgets were based on recent sales data for existing products, planned timing of new product launches or capital projects, and customer commitments related to new and existing products. These budgets also included
assumptions of future production volumes and pricing. We concluded that no impairment existed. Based on the sensitivity analysis performed, we determined that in the event that our estimates of projected future cash flows were too high by 10%, there
would still be no impact on the reported value of goodwill at December 31, 2009.

Due to the numerous variables
associated with our judgments and assumptions relating to the valuation of the reporting units and the effects of changes in circumstances affecting these valuations, both the precision and

reliability of the resulting estimates are subject to uncertainty, and as additional information becomes known, we may change our estimates.

Share-Based Compensation.    Our stock plan, the QIAGEN N.V. Amended and Restated 2005 Stock Plan
(the Plan), allows for the granting of stock rights, incentive stock options, as well as for non-qualified options, stock grants and stock-based awards. We use the Black-Scholes-Merton valuation model for estimating the fair value of our stock
option grants. Option valuation models, including Black-Scholes-Merton, require the input of highly subjective assumptions, including the risk-free rate of interest, expected dividend yield, expected volatility, and the expected life of the award.
Changes in the assumptions used can materially affect the grant date fair value of an award.

Income
Taxes.The calculation of our tax provision is complex due to the international operations and multiple taxing jurisdictions in which we operate. We have significant deferred tax assets due to net operating losses
(NOL). The utilization of NOLs is not assured and is dependent on generating sufficient taxable income in the future. Although management believes it is more likely than not that we will generate sufficient taxable income to utilize all NOL
carryforwards, evaluating the NOLs related to our newer subsidiaries requires us to make estimates that we believe are reasonable, but may also be highly uncertain given that we do not have direct experience with such subsidiaries or their products,
and thus the estimates also may be subject to significant changes from period to period as we gain that experience. To the extent that our estimates of future taxable income are insufficient to utilize all available NOLs, a valuation allowance will
be recorded in the provision for income taxes in the period the determination is made, and the deferred tax assets will be reduced by this amount, which could be material. In the event that actual circumstances differ from managements
estimates, or to the extent that these estimates are adjusted in the future, any changes to the valuation allowance could materially impact our financial position and results of operations.

Purchase Price Allocation.    The purchase price allocation for acquisitions requires extensive use
of accounting estimates and judgments to allocate the purchase price to the identifiable tangible and intangible assets acquired, including in-process research and development, and liabilities assumed based on their respective fair values.
Additionally, we must determine whether an acquired entity is considered to be a business or a set of net assets, because a portion of the purchase price can only be allocated to goodwill in a business combination.

We have made several acquisitions in recent years. The purchase prices for the acquisitions were allocated to tangible and intangible assets
acquired and liabilities assumed based on their estimated fair values at the acquisition dates. We engaged an independent third-party valuation firm to assist us in determining the estimated fair values of in-process research and development and
identifiable intangible assets. Such a valuation requires significant estimates and assumptions, including but not limited to, determining the timing and estimated costs to complete the in-process projects, projecting regulatory approvals,
estimating future cash flows, and developing appropriate discount rates. We believe the estimated fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions. However, the fair value estimates for the
purchase price allocations may change during the allowable allocation period, which is up to one year from the acquisition dates, if additional information becomes available.

The above listing is not intended to be a comprehensive list of all our accounting policies. In many cases, the accounting treatment of a
particular transaction is specifically dictated by generally accepted accounting principles in the United States, with limited or no need for managements judgment. There are also areas in which managements judgment in selecting available
alternatives may or may not produce a materially different result. See our audited consolidated financial statements and notes thereto in Item 18 of this Annual Report which contain a description of accounting policies and other disclosures
required by generally accepted accounting principles in the United States.

Chief Executive Officer and member of our Managing Board. In addition, Mr. Colpan continues to provide scientific advisory services to the Company. Dr. Colpan does not serve on any committees of the Supervisory Board.

Audit Committee

The Audit
Committee operates pursuant to a charter approved by the Supervisory Board and available online at www.qiagen.com. The Audit Committee consists of three members, Dr. Brandt (Chairman), Mr. Hornnaess and Mr. von Prondzynski, and
meets at least quarterly. The Audit Committee members are appointed by the Supervisory Board and serve for a term of one year. We believe that all members of our Audit Committee meet the independence requirements as set forth in Rule 10A-3 of the
Securities Exchange Act of 1934, as amended, and the Marketplace Rules of the NASDAQ. The Audit Committee reviews major financial risk exposures, pre-approves related-party transactions, and reviews any legal matter that could have a significant
impact on the financial statements. Further, the Audit Committee is responsible to establish complaint procedures, including confidential, anonymous submission by employees of concerns, for the receipt, retention and treatment of complaints received
regarding accounting, internal accounting controls, or auditing matters. The Audit Committee is also responsible together with the Managing Board for the proposal of the independent registered public accounting firm to the Supervisory Board, which
proposes the appointment of the independent registered public accounting firm to the General Meeting of shareholders. The independent registered public accounting firm audits the consolidated financial statements and certain local books and records
of QIAGEN and its subsidiaries, and the Audit Committee is further responsible for pre-approving the fees for such services. Additionally, the Audit Committee reviews the performance of the independent registered public accounting firm with
management, discussing on a quarterly basis the scope and results of the reviews and audits with the independent registered public accounting firm; discusses our financial accounting and reporting principles and policies and the adequacy of our
internal accounting, financial and operating controls and procedures with the independent registered public accounting firm and management; considers and approves any recommendations regarding changes to our accounting policies and processes;
reviews with management and the independent registered public accounting firm our quarterly earnings reports prior to their release to the press; and reviews the quarterly and annual reports (reported on Forms 6-K and 20-F) to be furnished to or
filed with the Securities and Exchange Commission and the Deutsche Boerse. The Board has designated Dr. Brandt as an audit committee financial expert as that term is defined in the United States Securities and Exchange Commission
rules adopted pursuant to the Sarbanes-Oxley Act of 2002.

Compensation Committee

The Compensation Committee operates pursuant to a charter approved by the Supervisory Board and available online at www.qiagen.com.
The Compensation Committee consists of two members, Mr. Erik Hornnaess (Chairman) and Professor Karobath. Members are appointed by the Supervisory Board and serve for a term of one year. We believe that all of the members of the Compensation
Committee meet the independence requirements set forth in the Marketplace Rules of the NASDAQ. The Compensation Committee reviews and approves all equity-based compensation, reviews and approves the annual salaries, bonuses and other benefits of
executive officers, and reviews general policies relating to employee compensation and benefits.

Selection and Appointment Committee

The Selection and Appointment Committee operates pursuant to a charter approved by the Supervisory Board and available online
at www.qiagen.com. The current members of the Selection and Appointment Committee are Prof. Dr. Detlev H. Riesner (Chairman) and Mr. Erik Hornnaess. Members are appointed by the Supervisory Board and serve for a term of
one year. The Selection and Appointment Committee prepares the selection criteria and appointment procedures for members of our Supervisory Board and Managing Board; periodically evaluates the scope and composition of the Managing Board and
Supervisory Board and proposes

Employees

As of December 31, 2009, we employed 3,495 individuals, 20% of whom worked in research and
development, 36% in sales, 24% in production/logistics, 7% in marketing and 13% in administration.

At December 31, 2008 and 2007, we employed 3,041
and 2,662 individuals, respectively. None of our employees is represented by a labor union or subject to a collective bargaining agreement. Management believes that its relations with employees are good.

Our success depends, to a significant extent, on key members of our management and our scientific staff. The loss of such employees could
have a material adverse effect on QIAGEN. 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 acquire such personnel or develop such expertise could
have a material adverse impact on our operations.

Stock Plans

We adopted the QIAGEN N.V. Amended and Restated 2005 Stock Plan (the Plan) which was approved by our shareholders on June 14, 2005.
Pursuant to the Plan, stock rights, which include options to purchase our Common Shares, stock grants and stock-based awards, may be granted to employees and consultants of QIAGEN

and its subsidiaries and to Supervisory Directors. An aggregate of 22,000,000 Common Shares have been reserved for issuance pursuant to the Plan, subject to certain antidilution adjustments.
Options granted pursuant to the Plan may either be incentive stock options within the meaning of Section 422 of the United States Internal Revenue Code of 1986, as amended (the Code), or non-qualified stock options. Options granted to members
of the Supervisory Board and the Managing Board must have an exercise price that is higher than the market price at the time of grant. Generally, each of the options has a term of ten years, subject to earlier termination in the event of death,
disability or other termination of employment. The vesting and exercisability of certain stock rights will be accelerated in the event of a Change of Control, as defined in the agreements under the Plan.

The Plan is administered by the Compensation Committee of the Supervisory Board, which selects participants from among eligible employees,
consultants and directors and determines the number of shares subject to the option, the length of time the option will remain outstanding, the manner and time of the options exercise, the exercise price per share subject to the option and
other terms and conditions of the option consistent with the Plan. The Compensation Committees decisions are subject to the approval of the Supervisory Board.

In connection with the acquisition of Digene Corporation during the third quarter of 2007, the Company assumed three additional equity incentive plans and exchanged Digene stock options and awards into
the Companys common stock. No new grants will be made under these plans.

The Compensation Committee has the power,
subject to Supervisory Board approval, to interpret the plans and to adopt such rules and regulations (including the adoption of sub plans applicable to participants in specified jurisdictions) as it may deem necessary or appropriate.
The Compensation Committee or the Supervisory Board may at any time amend the plans in any respect, subject to Supervisory Board approval, and except that (i) no amendment that would adversely affect the rights of any participant under any
option previously granted may be made without such participants consent and (ii) no amendment shall be effective prior to shareholder approval to the extent such approval is required to ensure favorable tax treatment for incentive stock
options or to ensure compliance with Rule 16b-3 under the United States Securities Exchange Act of 1934, as amended (the Exchange Act) at such times as any participants are subject to Section 16 of the Exchange Act.

As of January 25, 2010, there were 8.3 million options outstanding at prices ranging between $1.85 and $49.75 and expiring between
January 2010 and November 2019. The exercise price of the options is the fair market value of the Common Shares as of the date of grant or a premium above fair market value. Additionally there were 3.0 million restricted stock unit awards
outstanding as of January 25, 2010. These awards will be released between February 2010 and October 2019. As of January 25, 2010, options to purchase 4.0 million Common Shares and 1.4 million restricted stock units were held by
the officers and directors of QIAGEN, as a group.

LLC. This information is based solely on the Schedule 13G filed jointly by FMR LLC, Edward C. Johnson III, and Fidelity Management and Research Company with the Securities and Exchange Commission on February 16, 2010, which reported ownership
as of December 31, 2009. FMR Corp. reported that it beneficially owned 23,079,319 shares representing 11.67% of the total Common Shares issued and outstanding at December 31, 2008 and 28,386,926 shares representing 14.53% of the total

Our common stock is traded on the NASDAQ
Global Select Market in the United States, and on the Prime Standard Segment of the Frankfurt Stock Exchange in Germany. A significant portion of our shares are held in street name, therefore we generally have no way of determining who our
shareholders are, their geographical location or how many shares a particular shareholder owns. As of January 25, 2010, there were 181 shareholders of record of our common shares.

Control of Registrant

To our knowledge, we are not directly or indirectly owned or controlled by another corporation, by any foreign government, or by any other natural or legal person. As of January 25, 2010, the
officers and directors of QIAGEN as a group beneficially owned 7,852,255 Common Shares, or 3.38% of the then outstanding Common Shares.

Related Party Transactions

We have a consulting agreement with
Dr. Metin Colpan, our former Chief Executive Officer and current Supervisory Board member, pursuant to which Dr. Colpan is paid a fee of EUR 2,750 per day for scientific consulting services, subject to adjustment. During each of the
years ended December 31, 2009 and 2008, we paid approximately $0.2 million to Dr. Colpan for scientific consulting services under this agreement.

From time to time, we have transactions with companies in which we hold an interest all of which are individually and in sum immaterial except for certain transactions as discussed below.

We have a 50% interest in a joint venture company, PreAnalytiX GmbH, which is accounted for under the equity method. As of December 31,
2009 and 2008, we had accounts receivable from PreAnalytix of $1.0 million and $0.3 million, and accounts payable to PreAnalytix of $0.3 million, respectively.

During 2007, we made an initial investment of $747,000 in Dx Assays Pte Ltd, a joint venture with Bio*One Capital, which represents a 33.3% interest in Dx Assays Pte Ltd. In 2008, we made a $1.4 million
loan to Dx Assays, which bears interest at 15% and is due in March 2013. During the year ended December 31, 2009, we recorded sales of $1.8 million to Dx Assays. As of December 31, 2009, we had accounts receivable from Dx Assays of $2.1
million and accounts payable to Dx Assays of $0.9 million.

We have a 100% interest in QIAGEN Finance (Luxembourg) S.A.
(QIAGEN Finance) and QIAGEN Euro Finance (Luxembourg) S.A. (Euro Finance), which were established for the purpose of issuing convertible debt. As discussed in Note 10 of the Notes to the Consolidated Financial Statements, QIAGEN Finance and Euro
Finance are variable interest entities with no primary beneficiary, thus they are not consolidated. Accordingly, the convertible debt is not included in the consolidated statements of QIAGEN N.V., though we do report the full obligation of the debt
through our liabilities to QIAGEN Finance and Euro Finance. As of December 31, 2009 and 2008, we had a loan payable to QIAGEN Finance of $145.0 million and accrued interest due to QIAGEN Finance of $3.3 million and amounts receivable from
QIAGEN Finance of $2.3 million. As of December 31, 2009 and 2008, we had a loan payable to Euro Finance of $300.0 million, accrued interest due to Euro Finance of $3.0 million and amounts receivable from Euro Finance of $1.6 million.

Legal Proceedings

For information on legal proceedings, see Note 16 of the Notes to Condensed Consolidated Financial Statements.

While no assurances can be given regarding the outcome of proceedings described in Note 16, based on information currently available, we believe that the resolution of these matters is unlikely to have a
material adverse effect on our financial position or results of future operations for QIAGEN N.V. as a whole. However, because of the nature and inherent uncertainties of litigation, should the outcomes be unfavorable, certain aspects of our
business, financial condition, and results of operations and cash flows could be materially adversely affected.

Statement of Dividend
Policy

We have not paid any dividends on our Common Shares since our inception and do not intend to pay any dividends on
our Common Shares in the foreseeable future. We intend to retain our earnings, if any, for the development of our business.

transferred from the Neuer Markt segment of the Frankfurt Stock Exchange to the Prime Standard Segment of the Frankfurt Stock Exchange. The Neuer Markt segment was discontinued in 2004. The following table sets forth the annual high and low sale
prices for the last five years, the quarterly high and low sale prices for the last two fiscal years, and the monthly high and low sale prices for the last six months of our Common Shares on the Prime Standard.

|Item 10. | Additional Information
|-------- | ----------------------

Memorandum and Articles of Association

We are a public company with limited liability (naamloze
vennootschap) incorporated under Dutch law and registered with the Dutch Trade Register under file number 12036979. Set forth below is a summary of certain provisions of our full Articles of Association, as lastly amended on July 2, 2008,
or the Articles, and Dutch law, where appropriate. The Dutch Corporate Governance Code, or Code, that was published on December 9, 2003 (and revised on December 10, 2008) contains principles of good corporate governance and best practice
provisions. The Code contains the principles and concrete provisions which the persons involved in a listed company (including Managing Board members and Supervisory Board members) and stakeholders should observe in relation to one another. A listed
company should either comply with, or if not, explain in its annual report why and to what extent, it does not comply with the best practice provisions of the Code. The Code has been taken into account in the summary below.

This summary does not purport to be complete and is qualified in its entirety by reference to the Articles, Dutch Law and the Code.

Corporate Purpose

Our objects include, without limitation, the performance of activities in the biotechnology industry, as well as incorporating, acquiring, participating in, financing, managing and having any other interest in companies or enterprises of
any nature, raising and lending funds and such other acts as may be conducive to our business.

Managing Directors

QIAGEN shall be managed by a Managing Board consisting of one or more Managing Directors under the supervision of the Supervisory Board. The
majority view under Dutch law is that in managing QIAGEN, the Managing Directors must take into account our interests and our business and the interests of all stakeholders (which includes but is not limited to our shareholders). Managing Directors
shall be appointed by the General Meeting of our shareholders upon the joint meeting of the Supervisory Board and the Managing Board, or Joint Meeting, having made a binding nomination for each vacancy. However, the General Meeting may at all times
overrule the binding nature of such a nomination by a resolution adopted by at least a two-thirds majority of the votes cast, if such majority represents more than half the issued share capital. This is different from the provisions of many American
corporate statutes, including the Delaware General Corporation Law, which give the directors of a corporation greater authority in choosing the executive officers of a corporation. Under our Articles, the General Meeting may suspend or dismiss a
managing director at any time. The Supervisory Board shall also at all times be entitled to suspend (but not to dismiss) a Managing Director. The Articles provide that the Supervisory Board may adopt management rules governing the internal
organization of the Managing Board.

Furthermore, the Supervisory Board shall determine the salary, the bonus, if any, and the
other compensation terms and conditions of employment of the Managing Directors within the scope of the

##### Table of Contents

remuneration policy. The remuneration policy of the Managing Board has been adopted in our annual General Meeting on June 14, 2005.

Under Dutch law, in the event that there is a conflict of interest between a Managing Director and us, we are represented by the Supervisory
Board. However, the General Meeting should at all times in an event of a conflict of interest be given the opportunity to appoint a person who is authorized to represent QIAGEN in such event. According to the Code, any conflict of interest or
apparent conflict of interest between the company and Managing Directors should be avoided. Decisions to enter into transactions under which Managing Directors would have conflicts of interest that are of material significance to the Company and/or
to the relevant Managing Director require the approval of the Supervisory Board.

Supervisory Directors

The Supervisory Board shall be responsible for supervising the policy pursued by the Managing Board and our general course of affairs. Under
our Articles, the Supervisory Directors are required to serve our interests and our business and the interest of all stakeholders (which includes but is not limited to our shareholders) in fulfilling their duties. The Supervisory Board shall consist
of such number of members as the Joint Meeting may from time to time determine, with a minimum of three members. The Supervisory Directors shall be appointed by the General Meeting upon the Joint Meeting having made a binding nomination for each
vacancy. If during a financial year a vacancy occurs in the Supervisory Board, the Supervisory Board may appoint a Supervisory Director who will cease to hold office at the next Annual General Meeting. Under Dutch law and the Code, a Supervisory
Director must excuse him or herself in the case of any conflict of interest. Decisions to enter into transactions under which a Supervisory Director would have a conflict of interest that are of material significance to QIAGEN and/or to the
Supervisory Director concerned, require the approval of the Supervisory Board.

Under Dutch law and the Code, the General
Meeting determines the compensation of the Supervisory Directors upon the proposal of the Compensation Committee. Any shares held by a Supervisory Director in the company on whose board he sits should be long-term investments.

Under our Articles, the General Meeting may suspend or dismiss a Supervisory Director at any time. This is different from the provisions of
many American corporate statutes, including the Delaware General Corporation Law, which provides that directors may vote to fill vacancies on the board of directors of a corporation.

Liability of Managing Directors and Supervisory Directors

Under Dutch law,
as a general rule, Managing Directors and Supervisory Directors are not liable for obligations we incur. Under certain circumstances, however, they may become liable, either towards QIAGEN (internal liability) or to others (external liability),
although some exceptions are described below.

Liability Towards QIAGEN

Failure of a Managing or Supervisory Director to perform his or her duties does not automatically lead to liability. Liability is only
incurred in the case of a clear, indisputable shortcoming about which no reasonably judging business-person would have any doubt. In addition, the Managing or Supervisory Director must be deemed to have been grossly negligent. Managing Directors are
jointly and severally liable for failure of the Managing Board as a whole, but an individual Managing Director will not be held liable if he or she is determined not to have been responsible for the mismanagement and has not been negligent in
preventing its consequences. Supervisory Directors are jointly and severally liable for failure of the Supervisory Board as a whole, but an individual Supervisory Director will not be held liable if he or she is determined not to have been
responsible for the mismanagement and has not been negligent in preventing its consequences.

Liability for Misrepresentation in Annual Accounts

Managing and Supervisory Directors are also jointly and severally liable to any third party for damages suffered as a result of
misrepresentation in the annual accounts, annual report or interim statements of QIAGEN, although a Managing or Supervisory Director will not be held liable if found not to be personally responsible for the misrepresentation. Moreover, a Managing or
Supervisory Director may be found to be criminally liable if he or she deliberately publishes false annual accounts or deliberately allows the publication of such false annual accounts.

Tort Liability

Under Dutch law, there can be liability if one has
committed a tort (onrechtmatige daad) against another person. Although there is no clear definition of tort under Dutch law, breach of a duty of care towards a third party is generally considered to be a tort. Therefore, a Dutch
corporation may be held liable by any third party under the general rule of Dutch laws regarding tort claims. In exceptional cases, Managing Directors and Supervisory Directors have been found liable on the basis of tort under Dutch common law, but
it is generally difficult to hold a Managing or Supervisory Director personally liable for a tort claim. Shareholders cannot base a tort claim on any losses which derive from and coincide with losses we suffered. In such cases, only we can sue the
Managing or Supervisory Directors.

Criminal Liability

Under Dutch law, if a legal entity has committed a criminal offence, criminal proceedings may be instituted against the legal entity itself as well as against those who gave order to or were in charge of
the forbidden act. As a general rule, it is held that a Managing Director is only criminally liable if he or she played a reasonably active role in the criminal act.

Indemnification

Article 27 of our Articles provide that we shall indemnify
every person who is or was a Managing Director or Supervisory Directors against all expenses (including attorneys fees) judgments, fines and amounts paid in settlement with respect to any threatened pending or completed action, suit or
proceeding as well as against expenses (including attorneys fees) actually and reasonably incurred in connection with the defense or settlement of an action or proceeding, if such person acted in good faith and in a manner he reasonably could
believe to be in or not opposed to our best interests. An exception is made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for gross negligence or willful misconduct in the performance of his
duty to us.

Classes of Shares

The authorized classes of our shares consist of Common Shares, Financing Preference Shares and Preference Shares. No Financing Preference Shares or Preference Shares have been issued.

Common Shares

Common
Shares are issued in registered form only. Common Shares are available either without issue of a share certificate, or Type I shares, or with issue of a share certificate, or Type II shares, in either case in the form of an entry in the share
register. At the discretion of the Supervisory Board, Type I shares may be issued and the holders of such Type I shares will be registered in either our shareholders register with American Stock Transfer & Trust Company, or New York
Transfer Agent, our transfer agent and registrar in New York, or our shareholder register with TMF FundServices B.V., Westblaak 89, NL-3012 KG Rotterdam, the Netherlands. The Type II shares are registered with our New York Transfer Agent.

##### Table of Contents

The transfer of registered shares requires that we issue a written instrument of transfer
and the written acknowledgement of such transfer (or, in the case of Type II shares, the New York Transfer Agent (in our name)), and surrender of the share certificates, if any, to us or (in our name) to the New York Transfer Agent. Upon surrender
of a share certificate for the purpose of transfer of the relevant shares, we (or the New York Transfer Agent in our name) acknowledge the transfer by endorsement on the share certificate or by issuance of a new share certificate to the transferee,
at the discretion of the Managing Board.

Financing Preference Shares

No Financing Preference Shares are currently issued or outstanding. If issued, Financing Preference Shares will be issued in registered form
only. No share certificates are issued for Financing Preference Shares. Financing Preference Shares must be fully paid up upon issue. The preferred dividend rights attached to Financing Preference Shares are described under Dividends
below. We have no present plans to issue any Financing Preference Shares.

Preference Shares

No Preference Shares are currently issued or outstanding. If issued, Preference Shares will be issued in registered form only. No share
certificates are issued for Preference Shares. Only 25% of the nominal value thereof is required to be paid upon subscription for Preference Shares. The obligatory payable part of the nominal amount (or the call) must be equal for each Preference
Share. The Managing Board may, subject to the approval of the Supervisory Board, resolve on which day and up to which amount a further call must be paid on Preference Shares which have not yet been paid up in full. The preferred dividend rights
attached to Preference Shares are described under Dividends below.

Pursuant to our Articles and the resolution
adopted by our General Meeting on June 16, 2004, QIAGENs Supervisory Board is entitled to resolve to issue Preference Shares in case of an intended take-over of our Company by (i) any person who alone or with one or more other
persons, directly or indirectly, have acquired or given notice of an intent to acquire (beneficial) ownership of an equity stake which in aggregate equals 20% or more of our share capital then outstanding or (ii) an adverse person
as determined by the Supervisory Board. For this purpose, an adverse person is generally any (legal) person, alone or together with affiliates or associates, with an equity stake in our Company which the
Supervisory Board considers to be substantial and where the Supervisory Board is of the opinion that this (legal) person has engaged in an acquisition that is intended to cause or pressure QIAGEN to enter into transactions
intended to provide such person with short-term financial gain under circumstances that would not be in the interest of QIAGEN and our shareholders or whose ownership is reasonably likely to cause a material adverse impact on our business
prospects.

On August 2, 2004, we entered into an agreement, or Option Agreement, with Stichting Preferente Aandelen
QIAGEN, or SPAQ. Pursuant to the Option Agreement, SPAQ was granted an option to acquire such number of Preference Shares as are equal to the total number of all outstanding Common Shares minus one in our share capital at the time of the relevant
exercise of the right. The right to acquire Preference Shares is granted subject to the conditions referred to in the previous paragraph. Due to the implementation of the EC Directive on Takeover Bids in Dutch legislation, the exercise of the option
to acquire Preference Shares by SPAQ and the subsequent issuance of Preference Shares to SPAQ needs to be done with due observance and in consideration of the restrictions imposed by the Public Offer Rules.

SPAQ was incorporated on August 2, 2004. Its principal office is located at Spoorstraat 50, 5911 KJ Venlo, The Netherlands. Its
statutory objectives are to protect our interests and our enterprise and the enterprises of companies which are linked to us. SPAQ shall attempt to accomplish its objectives by way of acquiring Preference Shares in the share capital of QIAGEN and to
exercise the voting rights in our interests and the interests of our stakeholders.



65



---

##### Table of Contents

The board of SPAQ shall consist of at least two directors. Upon incorporation of SPAQ two
members were appointed to the board of SPAQ. Additional board members shall be appointed by the board of SPAQ. Board resolutions will be adopted by unanimity of the votes cast. SPAQ will be represented either by its board or by the chairman of its
board.

Pre-emptive Rights

Under our Articles, existing holders of Common Shares will have pre-emptive rights in respect of future issuances of Common Shares in proportion to the number of Common Shares held by them, unless limited
or excluded as described below. Holders of Common Shares shall not have pre-emptive rights in respect of future issuances of Financing Preference Shares or Preference Shares. Holders of Financing Preference Shares and Preference Shares shall not
have pre-emptive rights in respect of any future issuances of share capital. Pre-emptive rights do not apply with respect to shares issued against contributions other than in cash or shares issued to our employees or one of our group companies.
Under our Articles, the Supervisory Board has the power to limit or exclude any pre-emptive rights to which shareholders may be entitled, provided that it has been authorized by the General Meeting to do so. The authority of the Supervisory Board to
limit or exclude pre-emptive rights can only be exercised if at that time the authority to issue shares is in full force and effect. The authority to limit or exclude pre-emptive rights may be extended in the same manner as the authority to issue
shares. If there is no designation of the Supervisory Board to limit or exclude pre-emptive rights in force, the General Meeting shall have authority to limit or exclude such pre-emptive rights, but only upon the proposal of the Supervisory Board.

Resolutions of the General Meeting (i) to limit or exclude pre-emptive rights or (ii) to designate the Supervisory
Board as the corporate body that has authority to limit or exclude pre-emptive rights, require a majority of at least two-thirds of the votes cast in a meeting of shareholders if less than 50% of the issued share capital is present or represented.
For these purposes, issuances of shares include the granting of rights to subscribe for shares, such as options and warrants, but not the issue of shares upon exercise of such rights.

On July 20, 2007, the General Meeting resolved to authorize the Supervisory Board to issue Common Shares and Financing Preference
Shares or grant rights to subscribe to those shares for a period of 5 years commencing on October 11, 2007 and for a maximum of Common Shares and Financing Preference Shares included in our authorized share capital (as included in our
Articles).

The General Meeting of shareholders subsequently resolved to grant the authority to exclude or limit any
pre-emptive rights. However, the General Meeting has limited this authority in a way that the Supervisory Board can only exclude or limit the pre-emptive rights in relation to no more than 50% of the aggregate number of Common Shares and Financing
Preference Shares available to be issued or rights to subscribe for those shares available to be granted of our authorized but unissued share capital as of October 11, 2007. The authority to exclude or limit pre-emptive rights covers a period
of 5 years commencing as of October 11, 2007.

Acquisition of our Own Shares

We may acquire our own shares, subject to certain provisions of Dutch law and our Articles, if (i) shareholders equity less the
payment required to make the acquisition does not fall below the sum of paid-up and called-up capital and any reserves required by Dutch law or the Articles and (ii) we and our subsidiaries would not thereafter hold shares with an aggregate
nominal value exceeding half of our issued share capital. Shares that we hold in our own capital or shares held by one of our subsidiaries may not be voted. The Managing Board, subject to the approval of the Supervisory Board, may effect our
acquisition of shares in our own capital. Our acquisitions of shares in our own capital may only take place if the General Meeting has granted to the Managing Board the authority to effect such acquisitions. Such authority may apply for a maximum
period of 5 years and must specify the number of shares that may be acquired, the manner in which shares may be acquired and the price limits within which shares may be acquired. On June 24, 2009, the General Meeting resolved to

##### Table of Contents

extend the authorization of the Managing Board in such manner that the Managing Board may cause us to acquire shares in our own share capital, up to 10% of the outstanding shares, for an 18-month
period from June 24, 2009 until December 24, 2010, without limitation at a price between one Euro cent (Euro 0.01) and one hundred ten percent (110%) of the price for such shares on the NASDAQ Global Select Market for the five trading
days prior to the day of purchase, or, with respect to Preference and Finance Preference shares, against a price between one Euro cent (Euro 0.01) and three times the issuance price and in accordance with applicable provisions of Dutch law and our
Articles.

Capital Reduction

Subject to the provisions of Dutch law and our Articles, the General Meeting may, upon the proposal of the Supervisory Board, resolve to reduce the issued share capital by (i) canceling shares or
(ii) reducing the nominal value of shares through an amendment of our Articles. Cancellation with repayment of shares or partial repayment on shares or release from the obligation to pay up may also be made or given exclusively with respect to
Common Shares, Financing Preference Shares or Preference Shares.

Financial Year, Annual Accounts and Independent Registered Public
Accounting Firm

Our financial year coincides with the calendar year. Dutch law and our Articles require that within four
months after the end of our fiscal year, the Managing Board must make available a report with respect to such fiscal year, including our financial statements for such year prepared under International Financial Reporting Standards and accompanied by
a report of an Independent Registered Public Accounting Firm. The annual report is submitted to the annual General Meeting for adoption.

The General Meeting appoints an Independent Registered Public Accounting Firm to audit the financial statements and to issue a report thereon. On June 24, 2009, our shareholders appointed
Ernst & Young GmbH Wirtschaftsprüfungsgesellschaft to serve as our Independent Registered Public Accounting Firm for the fiscal year ending December 31, 2009.

Dividends and Other Distributions

Subject to certain exceptions, dividends
may only be paid out of profits as shown in our annual financial statements as adopted by the General Meeting. Distributions may not be made if the distribution would reduce shareholders equity below the sum of the paid-up capital and any
reserves required by Dutch law or our Articles.

Out of profits, dividends must first be paid on any outstanding Preference
Shares (the Preference Share Dividend) in a percentage (the Preference Share Dividend Percentage) of the obligatory call amount paid up on such shares at the beginning of the fiscal year in respect of which the distribution is made. The Preference
Share Dividend Percentage is equal to the average main refinancing rates during the financial year for which the distribution is made. Average main refinancing rate shall be understood to mean the average value on each individual day during the
financial year for which the distribution is made of the main refinancing rates prevailing on such day. The main refinancing rate shall be understood to mean the rate of the Main Refinancing Operation as determined and published from time to time by
the European Central Bank. If and to the extent that profits are not sufficient to pay the Preference Share Dividend in full, the deficit shall be paid out of the reserves, with the exception of any reserve, which was formed as share premium reserve
upon the issue of Financing Preference Shares. If in any fiscal year the profit is not sufficient to make the distributions referred to above and if no distribution or only a partial distribution is made from the reserves referred to above, such
that the deficit is not fully made good, no further distributions will be made as described below until the deficit has been made good.

Out of profits remaining after payment of any dividends on Preference Shares, the Supervisory Board shall determine such amounts as shall be kept in reserve as determined by the Supervisory Board. Out of
any

remaining profits not allocated to reserve, a dividend (the Financing Preference Share Dividend) shall be paid on the Financing Preference Shares equal to a percentage (the Financing Preference
Share Dividend Percentage) over the nominal value of the Financing Preference Shares, increased by the amount of share premium that was paid upon the first issue of Financing Preference Shares. The Financing Preference Shares Dividend Percentage
which percentage is related to a fixed average effective yield on the prime interest rate on corporate loans in the United States as quoted in the Wall Street Journal as set forth in article 40.4 of our Articles. If and to the extent that the
profits are not sufficient to pay the Financing Preference Share Dividend in full, the deficit may be paid out of the reserves if the Managing Board so decides with the approval of the Supervisory Board, with the exception of the reserve which was
formed as share premium upon the issue of Financing Preference Shares.

Insofar as the profits have not been distributed or
allocated to reserves as specified above, the General Meeting may act to allocate such profits, provided that no further dividends will be distributed on the Preference Shares or the Financing Preference Shares.

The General Meeting may resolve, on the proposal of the Supervisory Board, to distribute dividends or reserves, wholly or partially, in the
form of QIAGEN shares.

Distributions as described above are payable as from a date to be determined by the Supervisory Board.
The date of payment on Type I shares may differ from the date of payment on Type II shares. Distributions will be made payable at an address or addresses in The Netherlands to be determined by the Supervisory Board, as well as at least one address
in each country where the shares are listed or quoted for trading. The Supervisory Board may determine the method of payment of cash distributions, provided that cash distributions in respect of Type II shares will, subject to certain exceptions, be
paid in the currency of a country where our shares are listed or quoted for trading, converted at the close of business on a day to be determined for that purpose by the Supervisory Board. Distributions in cash that have not been collected within
five years and two days after they have become due and payable shall revert to QIAGEN.

Dutch law provides that the
declaration of dividends out of the profits that are at the free disposal of the General Meeting is the exclusive right of the General Meeting. This is different from the corporate law of most jurisdictions in the United States, which permit a
corporations board of directors to declare dividends.

Shareholder Meetings, Voting Rights and Other Shareholder Rights

The annual General Meeting is required to be held within six months after the end of each fiscal year for the purpose of,
among other things, adopting the annual accounts and filling of any vacancies on the Managing and Supervisory Boards.

Extraordinary General Meetings are held as often as deemed necessary by the Managing Board or Supervisory Board, or upon the request of one or more shareholders and other persons entitled to attend meetings jointly representing at least 40%
of our issued share capital or by one or more shareholders jointly representing at least 10% of our issued share capital as provided for and in accordance with the laws of The Netherlands.

General Meetings are held in Amsterdam, Haarlemmermeer (Schiphol Airport), Arnhem, Maastricht, Rotterdam, Venlo or The Hague. The notice
convening a General Meeting must be given to the shareholders by advertisement in at least one national daily newspaper published in The Netherlands no later than the fifteenth day prior to the meeting. The notice will contain the agenda for the
meeting or state that the agenda can be obtained at our offices.

The agenda shall contain such subjects to be considered at
the General Meeting, as the persons convening or requesting the meeting shall decide. Under Dutch law, holders of shares representing solely or jointly at least one hundredth part of the issued share capital, or representing a value of at least EUR
50,000,000 may request QIAGEN not later than on the sixtieth day prior to the day of the General Meeting, to include certain subjects on

##### Table of Contents

the notice convening a meeting, provided that it is not detrimental to the vital interest of the company. No valid resolutions can be adopted at a General Meeting in respect of subjects which are
not mentioned in the agenda.

General Meetings are presided over by the chairman of the Supervisory Board or, in his absence,
by any person nominated by the Supervisory Board.

At the General Meeting, each share shall confer the right to cast one vote,
unless otherwise provided by law or our Articles. No votes may be cast in respect of shares that we or our subsidiaries hold, or by usufructuaries and pledgees. All shareholders and other persons entitled to vote at General Meetings are entitled to
attend General Meetings, to address the meeting and to vote. They must notify the Managing Board in writing of their intention to be present or represented not later than on the third day prior to the day of the meeting, unless the Managing Board
permits notification within a shorter period of time prior to any such meeting. Subject to certain exceptions, resolutions may be passed by a simple majority of the votes cast.

Except for resolutions to be adopted by the meeting of holders of Preference Shares, our Articles do not allow the adoption of shareholders
resolutions by written consent (or otherwise without holding a meeting).

A resolution of the General Meeting to amend our
Articles, dissolve QIAGEN, issue shares or grant rights to subscribe for shares or limit or exclude any pre-emptive rights to which shareholders shall be entitled is valid only if proposed to the General Meeting by the Supervisory Board.

A resolution of the General Meeting to amend our Articles is further only valid if the complete proposal has been made available for
inspection by the shareholders and the other persons entitled to attend General Meetings at our offices as from the day of notice convening such meeting until the end of the meeting. A resolution to amend our Articles to change the rights attached
to the shares of a specific class requires the approval of the relevant class meeting.

Resolutions of the General Meeting in
a meeting that has not been convened by the Managing Board and/or the Supervisory Board, or resolutions included on the agenda for the meeting at the request of shareholders, will be valid only if adopted with a majority of two-thirds of votes cast
representing more than half the issued share capital, unless our Articles require a greater majority or quorum. Our Articles do not provide for shareholders to act by written consent outside of a General Meeting.

A resolution of the General Meeting to approve a legal merger or the sale of all or substantially all of our assets is valid only if adopted
by a vote of at least two-thirds of the issued share capital, unless proposed by the Supervisory Board, in which case a simple majority of the votes cast shall be sufficient.

A shareholder shall upon request be provided, free of charge, with written evidence of the contents of the share register with regard to the
shares registered in its name. Furthermore, any shareholder shall, upon written request, have the right, during normal business hours, to inspect our share register and a list of our shareholders and their addresses and shareholdings, and to make
copies or extracts therefrom. Such request must be directed to our Managing Directors at our registered office in the Netherlands or at our principal place of business. Financial records and other company documents (other than those made public) are
not available in this manner for shareholder review, but an extract of the minutes of the General Meeting shall be made available.

According to Dutch law and our Articles, certain resolutions of the Managing Board regarding a significant change in the identity or nature of us or our enterprise are subject to the approval of the General Meeting. The following
resolutions of the Managing Board acquire the approval of the General Meeting in any event:



| | (i) | the transfer of our enterprise or practically our entire enterprise to a third party;
| | --- | -------------------------------------------------------------------------------------



| | (ii) | the entry into or termination of a long-term cooperation by us or one of our subsidiaries (dochtermaatschappijen) with another legal person or

No Derivative Actions; Right to Request Independent Inquiry

Dutch law does
not afford shareholders the right to institute actions on behalf of us or in our interest. Shareholders holding at least one-tenth of our issued capital, or EUR 225,000, in nominal amount of our shares may inform the Managing Board and the
Supervisory Board of their objections as to our policy or the course of our affairs and, within a reasonable time thereafter, may request the Enterprises Division of the Court of Appeal in Amsterdam to order an inquiry into the policy and the course
of our affairs by independent investigators. If such an inquiry is ordered and the investigators conclude that there has been mismanagement, the shareholders can request the Division to order certain measures such as a suspension or annulment of
resolutions.

Dissolution and Liquidation

The General Meeting may resolve to dissolve QIAGEN. If QIAGEN is dissolved, the liquidation shall be carried out by the person designated for that purpose by the General Meeting, under the supervision of
the Supervisory Board. The General Meeting shall upon the proposal of the Supervisory Board determine the remuneration payable to the liquidators and to the person responsible for supervising the liquidation.

During the liquidation process, the provisions of our Articles will remain applicable to the extent possible.

In the event of our dissolution and liquidation, the assets remaining after payment of all debts and liquidation expenses will be
distributed among registered holders of Common Shares in proportion to the nominal value of their Common Shares, subject to liquidation preference rights of holders of Preference Shares and Financing Preference Shares, if any.

Restrictions on Transfer of Preference Shares

The Supervisory Board, upon application in writing, must approve each transfer of Preference Shares. If approval is refused, the Supervisory Board will designate prospective purchasers willing and able to
purchase the shares, otherwise the transfer will be deemed approved.

Limitations in our Articles on Rights to Own Securities

Other than with respect to usufructuaries and pledgees who have no voting rights, our Articles do not impose limitations
on rights to own our securities.

Provisions which may Defer or Prevent a Change in Control

The Option Agreement and our Articles could, under certain circumstances, prevent a third party from obtaining a majority of the voting
control of our shares by issuing Preference Shares. Pursuant to the Articles (and pursuant to the resolution adopted by our General Meeting on June 16, 2004), the Supervisory Board is authorized to issue Preference Shares if (i) a person
has (directly or indirectly) acquired or has expressed a desire to acquire, more than 20% of our issued capital or (ii) a person holding at least a 10% interest in us has been designated as an adverse person by the Supervisory
Board. Under the Option Agreement, SPAQ could acquire Preference Shares subject to the provisions mentioned in this paragraph.

##### Table of Contents

If the Supervisory Board opposes an intended take-over and authorizes the issuance of
Preference Shares, the bidder may withdraw its bid or enter into negotiations with the Managing Board and/or Supervisory Board and agree on a higher bid price for our shares.

Due to the implementation of the EC Directive or Takeover Bids, or 13thDirective, in Dutch legislation, shareholders who obtain control of a company are obliged to make a
mandatory offer to all other shareholders. The threshold for a mandatory offer is set at the ability to exercise 30% of the voting rights at the General Meeting of shareholders in a Dutch public limited company (naamloze vennootschap) whose
securities are admitted to trading on a regulated market in the EU, such as QIAGEN.

Ownership Threshold Requiring Disclosure

Our Articles do not provide an ownership threshold above which ownership must be disclosed. However there are statutory
requirements to disclose share ownership above certain thresholds under Dutch law  see Obligation of Shareholders to Disclose Major Holdings.

Exchange Controls

There are currently no limitations either under the laws
of The Netherlands or in our Articles, to the rights of shareholders from outside The Netherlands to hold or vote Common Shares. Under current foreign exchange regulations in The Netherlands, there are no material limitations on the amount of cash
payments that we may remit to residents of foreign countries.

Obligation of Shareholders to Disclose Major Holdings

Certain holders of our shares or rights to acquire shares (which include options and convertible bonds) are subject to notification
obligations under Chapter 5.3 of the Dutch Financial Markets Supervision Act, or the FMSA.

Under Chapter 5.3 of the FMSA, any
person who, directly or indirectly, acquires or disposes of an interest (including potential interest, such as options and convertible bonds) in our capital or voting rights must immediately notify the Netherlands Authority for the Financial
Markets, or AFM, by means of a standard form, if as a result of such acquisition or disposal, the percentage of capital interest or voting rights held by such person in QIAGEN reaches, exceeds or falls below any of the following thresholds: 5% (a
bill is being considered that would add a threshold of 3%), 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 75% and 95% of the voting rights or capital interests in the issued capital of QIAGEN. A notification requirement also applies if a persons
capital interest or voting rights reach, exceed or fall below the above mentioned thresholds as a result of a change in our total share capital or voting rights. Such notification has to be made no later than the fourth trading day after the AFM has
published our notification as described below. We are required to notify the AFM immediately of the changes to our total share capital or voting rights if our share capital or voting rights changes by 1% or more since our previous notification. We
must furthermore quarterly notify the AFM within eight days after the end of the relevant quarter, in the event our share capital or voting rights changed by less than 1% in that relevant quarter since our previous notification.

Furthermore, every holder of 5% (a bill is being considered that would add a threshold of 3%) or more of our share capital or voting rights
whose interest at December 31 at midnight differs from a previous notification to the AFM, as a result of certain acts (including but not limited to the exchange of our shares for depository receipts and the exercise of a right to acquire our
shares) must notify the AFM within four weeks. Controlled entities, within the meaning of the FMSA, do not have notification obligations under the FMSA, as their direct and indirect interests are attributed to their (ultimate) parent. Any person may
qualify as a parent for purposes of the FMSA, including an individual. A person who has a 5% (a bill is being considered that would reduce this threshold to 3%) or larger interest in our share capital or voting rights and who ceases to be a
controlled entity for

##### Table of Contents

these purposes must immediately notify the AFM. As of the date of that notification, all notification obligations under the FMSA will become applicable to that entity. For the purpose of
calculating the percentage of capital interest or voting rights, among other metrics, the following interests must be taken into account: (i) our shares or voting rights on our shares directly held (or acquired or disposed of) by a person,
(ii) our shares or voting rights on our shares held (or acquired or disposed of) by such persons subsidiaries or by a third party for such persons account or by a third party with whom such person has concluded an oral or written
voting agreement (including a discretionary power of attorney), and (iii) our shares or voting rights on our shares which such person, or any subsidiary or third party referred to above, may acquire pursuant to any option or other right held by
such person (or acquired or disposed of, including, but not limited to, on the basis of convertible bonds). Special rules apply with respect to the attribution of our shares or voting rights on our shares which are part of the property of a
partnership or other community of property. A holder of a pledge or right of usufruct (vruchtgebruik) in respect of our shares can also be subject to the notification obligations of the FMSA, if such person has, or can acquire, the right to
vote on our shares or, in the case of depository receipts, our underlying shares. The acquisition of (conditional) voting rights by a pledgee or usufructuary may also trigger the notification obligations as if the pledgee or beneficial owner were
the legal holder of our shares or voting rights on our shares.

The AFM does not issue separate public announcements of these
notifications. It does, however, keep a public register of all notifications under the FMSA on its website www.afm.nl. Third parties can request to be notified automatically by e-mail of changes to the public register in relation to a particular
companys shares or a particular notifying party.

Non-compliance with the notification obligations under the FMSA may
lead to criminal fines, administrative fines, imprisonment or other sanctions. In addition, non-compliance with the shareholding disclosure obligations under the FMSA may lead to civil sanctions, including suspension of the voting rights relating to
our shares held by the offender for a period of not more than three years and a prohibition applicable to the offender to acquire any of our shares or voting rights on our shares for a period of up to five years.

Taxation

The following is a general summary of certain material United States federal income and The Netherlands tax consequences to holders of our Common Shares (collectively, U.S. Holders) who are (i) citizens or residents of the
United States, (ii) entities subject to U.S. corporate tax, (iii) certain pension trusts and other retirement or employee benefits organizations established in the United States but generally exempt from U.S. tax, (iv) certain
not-for-profit organizations established in the United States but generally exempt from U.S. tax, (v) United States regulated investment companies, United States real estate investment trusts, and United States real estate mortgage conduits,
and (vi) partnerships or similar pass-through entities, estates, and trusts to the extent the income of such partnerships, similar entities, estates, or trusts is subject to tax in the United States as income of a resident in its hands or the
hands of its partners, beneficiaries, or grantors. This summary does not discuss every aspect of such taxation that may be relevant to U.S. Holders. Therefore, all prospective purchasers of our Common Shares who would be U.S. Holders are advised to
consult their own tax advisor with respect to the United States federal, state and local tax consequences, as well as the Netherlands tax consequences, of the ownership of our Common Shares. This summary is based upon the advice of Mintz, Levin,
Cohn, Ferris, Glovsky and Popeo, P.C. with respect to tax consequences for U.S. Holders and Baker & McKenzie with respect to tax consequences under Netherlands law.

The statements of The Netherlands and United States tax laws set out below are based on the laws in force as of the date of this Annual
Report on Form 20-F, and as a consequence are subject to any changes in United States or The Netherlands law, or in the double taxation conventions between the United States and The Netherlands, occurring after such date.

Netherlands Tax Considerations

The following describes the material tax consequences under Netherlands law of an investment in our Common Shares. Such description is based
on current Netherlands law as interpreted under officially published case law, and is limited to the tax implications for an owner of our Common Shares who is not, or is not deemed to be, a resident of The Netherlands for purposes of the relevant
tax codes (a non-resident Shareholder or Shareholder).

Dividend Withholding Tax

General.Upon distribution of dividends, we would be obligated to withhold 15% dividend tax at source
and to pay the amount withheld to The Netherlands tax authorities. The term dividends means income from shares or other rights participating in profits, as well as income from other corporate rights that is subjected to the same taxation
treatment as income from shares by the laws of The Netherlands. Dividends include dividends in cash or in kind, constructive dividends, certain repayments of capital qualified as dividends, interest on loans that are treated as equity for
Netherlands corporate income tax purposes and liquidation proceeds in excess of, for Netherlands tax purposes, recognized paid-in capital. Stock dividends are also subject to withholding tax, unless derived from our paid-in share premium which is
recognized as equity for Netherlands tax purposes.

No withholding tax applies on the proceeds resulting from the sale or
disposition of our Common Shares to persons other than QIAGEN and our affiliates.

A Shareholder can be eligible for a
reduction or a refund of Netherlands dividend withholding tax under a tax convention which is in effect between the country of residence of the Shareholder and The Netherlands. The Netherlands has concluded such conventions with, among others, the
United States, Canada, Switzerland, Japan and virtually all EU Member States.

U.S.
Shareholders.Under the Tax Convention between The Netherlands and the United States (the Convention), the regular 15% withholding tax on dividends we pay to a resident of the United States (as defined in
the Convention) who is entitled to the benefits of the Convention, may be reduced to 5% (in the case of a corporate U.S. Shareholder that holds 10% or more of the voting power of a Netherlands company) unless such U.S. shareholder has a permanent
establishment in The Netherlands with which the shares are effectively connected.

A full exemption from Netherlands
withholding tax may apply to certain U.S. corporate shareholders owning at least 80% of QIAGEN voting power for a period of at least twelve months prior to the distribution.

Dividends we pay to U.S. pension funds and U.S. tax exempt organizations may be eligible for an exemption from dividend withholding tax.

Dividend Stripping.    A refund, reduction, exemption, or credit of Netherlands dividend
withholding tax on the basis of Netherlands tax law or on the basis of a tax treaty between The Netherlands and another state, will only be granted if the dividends are paid to the beneficial owner (uiteindelijk gerechtigde) of
the dividends. A recipient of a dividend is not considered to be the beneficial owner of a dividend in an event of dividend stripping, in which he has paid a consideration related to the receipt of such dividend. In general terms,
dividend stripping can be described as the situation in which a foreign or domestic person (usually, but not necessarily, the original shareholder) has transferred his shares or his entitlement to the dividend distributions to a party
that has a more favorable right to a refund or reduction of Netherlands dividend withholding tax than the foreign or domestic person. In these situations, the foreign or domestic person (usually the original shareholder) avoids Netherlands dividend
withholding tax while retaining his beneficial interest in the shares and the dividend distributions, by transferring his shares or his entitlement to the dividend distributions.

Income Tax and Corporate Income Tax

General.    A non-resident Shareholder will not be subject to Netherlands income tax with respect to
dividends we distribute on our Common Shares or with respect to capital gains derived from the sale or disposition of our Common Shares, provided that:

(a) the non-resident Shareholder has not made an election for the application of the rules of The Netherlands 2001 Income Tax Act as they apply to residents of The Netherlands;

(b) the non-resident Shareholder does not carry on or have an interest in a business in The Netherlands through a permanent
establishment or a permanent representative to which or to whom the Common Shares are attributable or deemed to be attributable;

(c) the non-resident Shareholder does not have a direct or indirect substantial or deemed substantial interest (aanmerkelijk belang,as defined in the Netherlands tax code) in our share
capital or, in the event the Shareholder does have such a substantial interest, such interest is a business asset; and

(d) the non-resident Shareholder is not entitled to a share in the profits of an enterprise, to which our Common Shares are attributable and that is effectively managed in The Netherlands, other than by
way of securities or through an employment contract.

In general terms, a substantial interest (aanmerkelijk
belang) in our share capital does not exist if the Shareholder (individuals as well as corporations), alone or together with his partner, does not own, directly or indirectly, 5% or more of the nominal paid-in capital of, or any class of
our shares, does not have the right to acquire 5% or more of the nominal paid-in capital of, or any class of our shares (including a call option) and does not have the right to share in our profit or liquidation revenue amounting to 5% or more of
the annual profits or liquidation revenue.

There is no all-encompassing definition of the term business asset;
whether this determination can be made in general depends on the facts presented and in particular on the activities performed by the Shareholder. If the Shareholder materially conducts a business activity, while the key interest of his investment
in our Shares will not be his earnings out of the investment in our Shares but our economic activity, an investment in our Shares will generally be deemed to constitute a business asset, in particular if the Shareholders involvement in our
business will exceed regular monitoring of his investment in our Shares.

U.S.
Shareholders.    Pursuant to the Convention, the gain derived by a U.S. Shareholder from an alienation of our Common Shares constituting a substantial interest of the Shareholder in QIAGEN, not effectively connected or
deemed connected with a permanent establishment or permanent representative of the Shareholder in The Netherlands, is not subject to Netherlands income tax or corporate income tax, provided that the gain from the alienation of our Common Shares is
not derived by an individual Shareholder who has, at any time during the five-year period preceding such alienation, been a resident of The Netherlands according to Netherlands tax law and who owns, at the time of the alienation, either alone or
together with close relatives, at least 25% of any class of our shares.

Gift and Inheritance Tax

A gift or inheritance of our Common Shares from a non-resident Shareholder will generally not be subject to a Netherlands gift and
inheritance tax, provided that the Shareholder does not own a business which is, in whole or in part, carried on through a permanent establishment or a permanent representative in The Netherlands to which or to whom our Common Shares are
attributable. The Netherlands has concluded a tax convention with the United States based on which double taxation on inheritances may be avoided if the inheritance is subject to Netherlands and/or U.S. inheritance tax and the deceased was a
resident of either The Netherlands or the United States.

United States Federal Income Tax Considerations

The following summarizes the material U.S. federal income tax consequences of the ownership of our Common Shares by an investor that
purchases such Common Shares and that will hold the Common Shares as capital assets. This summary does not purport to be a complete analysis or listing of all potential tax considerations and does not address holders subject to special treatment
under U.S. federal income tax laws (including insurance companies, tax-exempt organizations, regulated investment companies, financial institutions, broker dealers or holders that own, actually or constructively, 10% or more of our voting shares).

As used herein, references to a U.S. Holder are to a holder of our Common Shares that is (i) a citizen or
resident of the United States, (ii) a corporation organized under the laws of the United States or any political subdivision thereof, or (iii) a person or entity otherwise subject to United States federal income taxation on a net income
basis with respect to our Common Shares (including a non-resident alien or foreign corporation that holds, or is deemed to hold, our Common Shares in connection with the conduct of a U.S. trade or business); and references to a non-U.S.
Holder are to a holder that is not a U.S. person for U.S. federal income tax purposes.

Taxation of Dividends

To the extent paid out of our current or accumulated earnings and profits, as determined under U.S. federal income tax principles,
distributions, if any, made with respect to our Common Shares will be includable for U.S. federal income tax purposes in the income of a U.S. Holder as ordinary dividend income in an amount equal to the sum of any cash and the fair market value of
any property that we distribute, before reduction for Netherlands withholding tax. For tax years beginning before 2011, such dividends will be eligible to be treated by U.S. Holder individuals as qualified dividend income subject to a
maximum tax rate of 15 percent, if the shareholder receiving the dividend satisfies the holding period requirements, and if we are not treated for our taxable year in which the dividend is paid, or our preceding taxable year, as a passive foreign
investment company (see TaxationUnited States Federal Income Tax ConsiderationsPassive Foreign Investment Company Status). To the extent that such distribution exceeds our current or accumulated earnings and profits, it will
be treated as a non-taxable return of capital to the extent of the U.S. Holders adjusted tax basis in our Common Shares and thereafter as taxable capital gain. Dividends generally will be treated as income from sources outside the United
States and generally will be passive income (or, in the case of certain holders, financial services income) for purposes of the foreign tax credit limitation. Dividends we pay will not be eligible for the dividends received deduction
allowed to corporations in certain circumstances under the United States Internal Revenue Code of 1986, as amended (the Code). A U.S. Holder may elect annually to either deduct The Netherlands withholding tax (see TaxationNetherlands Tax
ConsiderationsDividend Withholding Tax) against their income (in which case, the election will apply to all foreign income taxes such U.S. Holder paid in that year) or take the withholding taxes as a credit against their U.S. tax
liability, subject to U.S. foreign tax credit limitation rules. If the dividends are qualified for the lower applicable capital gains rate (as discussed in the above paragraph), the amount of the dividend income taken into account for calculating
the foreign tax credit limitation will be in general be limited to the gross amount of the dividend, multiplied by the reduced rate, divided by the highest rate of tax normally applicable to dividends. The rules governing the foreign tax credit are
complex. We urge you to consult with your own tax advisors regarding the availability of the foreign tax credit in your particular circumstances.

Dividends we pay in a currency other than the U.S. dollar will be included in the income of a U.S. Holder in a U.S. dollar amount based upon the exchange rate in effect on the date of receipt. A U.S.
Holder will have a tax basis in such foreign currency for U.S. federal income tax purposes equal to its U.S. dollar value on the date of receipt. Any gain or loss on a subsequent disposition of such foreign currency (including a subsequent
conversion into U.S. dollars) will be ordinary income or loss. Such gain or loss will generally be income from sources within the U.S. for foreign tax credit limitation purposes.

A non-U.S. Holder generally will not be subject to U.S. federal income tax or withholding tax on distributions with respect to our Common
Shares that are treated as dividend income for U.S. federal income tax

##### Table of Contents

purposes unless such dividends are effectively connected with the conduct of a trade or business within the United States by such non-U.S. Holder, (and are attributable to a permanent
establishment maintained in the United States by such non-U.S. Holder, if an applicable income tax treaty so requires as a condition for such non-U.S. Holder to be subject to U.S. taxation on a net income basis in respect of income from our Common
Shares), in which case the non-U.S. Holder generally will be subject to tax in respect of such dividends in the same manner as a U.S. Holder. Any such effectively connected dividends received by a non-United States corporation may also, under
certain circumstances, be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. A non-U.S. Holder generally will not be subject to U.S. federal income tax or
withholding tax on distributions with respect to our Common Shares that are treated as capital gain for U.S. federal income tax purposes unless such holder would be subject to U.S. federal income tax on gain realized on the sale or other disposition
of our Common Shares, as discussed below.

Taxation of Capital Gains

Subject to the PFIC rules discussed below, upon the sale or other disposition of our Common Shares, a U.S. Holder will recognize gain or loss
for U.S. federal income tax purposes in an amount equal to the difference between the amount realized on the disposition of our Common Shares and the U.S. Holders adjusted tax basis in our Common Shares. Such gain or loss generally will be
subject to U.S. federal income tax. An individual U.S. Holder is generally subject to a maximum capital gains rate of 15% for our Common Shares held for more than a year. For U.S. federal income tax purposes, capital losses are subject to
limitations on deductibility. Gain realized by a U.S. Holder on the sale or other disposition of our Common Shares generally will be treated as income from sources within the United States for purposes of the foreign tax credit limitation.

A non-U.S. Holder will not be subject to U.S. federal income tax or withholding tax on gain realized on the sale or other
disposition of our Common Shares unless (i) the gain is effectively connected with a trade or business of the non-U.S. Holder in the United States (and is attributable to a permanent establishment maintained in the United States by such
non-U.S. Holder, if an applicable income tax treaty so requires as a condition for such non-U.S. Holder to be subject to U.S. taxation on a net income basis in respect of gain from the sale or other disposition of our Common Shares) or
(ii) such holder is an individual who is present in the United States for 183 days or more in the taxable year of the sale, and certain other conditions are met. Effectively connected gains realized by a corporate Non-U.S. Holder may also,
under certain circumstances, be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

Passive Foreign Investment Company Status

We may be classified as a
passive foreign investment company (PFIC) for U.S. federal income tax purposes if certain tests are met. We will be a PFIC with respect to a U.S. Holder if for any taxable year in which the U.S. Holder held our Common Shares,
either (i) 75% or more of our gross income for the taxable year is passive income; or (ii) the average value of our assets (during the taxable year) which produce or are held for the production of passive income is at least 50% of the
average value of all assets for such year. Passive income means, in general, dividends, interest, royalties, rents (other than rents and royalties derived in the active conduct of a trade or business and not derived from a related person),
annuities, and gains from assets which would produce such income other than sales of inventory. For the purpose of the PFIC tests, if a foreign corporation owns at least 25% by value of the stock of another corporation, the foreign corporation is
treated as owning its proportionate share of the assets of the other corporation, and as if it had received directly its proportionate share of the income of such other corporation. The effect of this special provision with respect to QIAGEN and our
ownership of our subsidiaries is that we, for purposes of the income and assets tests described above, will be treated as owning directly our proportionate share of the assets of our subsidiaries and of receiving directly our proportionate share of
each of those companies income, if any, so long as we own, directly or indirectly, at least 25% by value of the particular companys stock. Active business income of our subsidiaries will be treated as our active business income, rather
than as passive income. Based on our current income, assets and activities, we do not believe that we are currently a PFIC. No assurances can be made, however, that the IRS will not challenge

this position or that we will not subsequently become a PFIC. Following the close of any tax year, we intend to promptly send a notice to all shareholders of record at any time during such year,
if we determine that we are a PFIC.

Prospective purchasers of our Common Shares are urged to consult their tax advisors
regarding the PFIC rules and their effect on an investment in our Common Shares, with particular regard to (i) the advisability of making the qualified election in the event that we notify the shareholders that we have become a PFIC in any
taxable year, or (ii) the advisability of making the mark-to-market election provided in the tax law.

Backup Withholding and
Information Reporting

In general, dividend payments, or other taxable distributions, paid within the United States or
through certain U.S.-related financial intermediaries on our Common Shares will be subject to information reporting requirements and backup withholding tax at the rate of 28% for a non-corporate United States person and, who also:



| |  |  | fails to provide an accurate taxpayer identification number;
| | - |  | ------------------------------------------------------------



| |  |  | is notified by the Internal Revenue Service that the individual has failed to report all interest or dividends required to be shown on the Federal
income tax returns; or
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in certain circumstances, fails to comply with applicable certification requirements.
| | - |  | -------------------------------------------------------------------------------------

Certain corporations and persons that are not United States persons may be required to establish their exemption from information reporting
and backup withholding by certifying their status on Internal Revenue Service Form W-8 or W-9.

If a United States person
sells our Common Shares to or through a United States office of a broker, the payment of the proceeds is subject to both United States backup withholding and information reporting unless the individual can certify that they are a non-U.S. person,
under penalties of perjury, or they otherwise establish an exemption. If a United States person sells our Common Shares through a non-U.S. office of a non-U.S. broker and the sale proceeds are paid to the person outside the United States then
information reporting and backup withholding generally will not apply to that payment. However, United States information reporting requirements, but not backup withholding, will apply to a payment of sales proceeds, even if that payment is made to
the United States person outside the United States, if the person sells our Common Shares through a non-U.S. office of a broker that is a U.S. person or has certain other contacts with the United States.

A Holder generally may obtain a refund of any amounts withheld under the backup withholding rules that exceed such holders income tax
liability by filing a refund claim with the United States Internal Revenue Service.

Foreign Currency Issues

If dividends are paid in euros, the amount of the dividend distribution included in the income of a U.S. Holder will be the U.S. dollar value
of the payments made in euros, determined at a spot, euro/U.S. dollar rate applicable to the date such dividend is includible in the income of the U.S. Holder, regardless of whether the payment is in fact converted into U.S. dollars. Generally, gain
or loss (if any) resulting from currency exchange fluctuations during the period from the date the dividend is paid to the date such payment is converted into U.S. dollars will be treated as ordinary income or loss. We have never paid cash dividends
on our share capital and do not intend to do so for the foreseeable future.

|Item 11. | Quantitative and Qualitative Disclosures About Market Risk
|-------- | ----------------------------------------------------------

Our market risk relates primarily to interest rate exposures on cash, marketable securities and borrowings and foreign currency exposures. Financial risk is centrally managed and is regulated by internal
guidelines which require a continuous internal risk analysis. The overall objective of our risk management is to reduce the potential negative earnings effects from changes in interest and foreign exchange rates. Exposures are managed through
operational methods and financial instruments relating to interest rate and foreign exchange risks. In the ordinary course of business, we use derivative instruments, including swaps, forwards and/or options, to manage potential losses from foreign
currency exposures and variable rate debt. The principal objective of such derivative instruments is to minimize the risks and/or costs associated with global financial and operating activities. We do not utilize derivative or other financial
instruments for trading or other speculative purposes. All derivatives are recognized as either assets or liabilities in the balance sheet and are measured at fair value with any change in fair value recognized in earnings in the period of change,
unless the derivative qualifies as an effective hedge that offsets certain exposures. In determining fair value, we consider both the counterparty credit risk and our own creditworthiness.

Foreign Currency Derivatives.As a globally active enterprise, we are subject to risks associated with
fluctuations in foreign currencies in our ordinary operations. This includes foreign currency-denominated receivables, payables, debt, and other balance sheet positions. We manage our balance sheet exposure on a group-wide basis primarily using
foreign exchange forward contracts and cross-currency swaps.

Interest Rate
Derivatives.We use interest rate derivative contracts on certain borrowing transactions to hedge fluctuating interest rates. We have entered into interest rate swaps in which we agree to exchange, at specified
intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount.

We make use of economic hedges, i.e. derivatives that do not have a formally designated hedging relationship as well as accounting hedges. All derivatives that qualify for hedge
accounting are cash-flow hedges. Further details of our derivative and hedging activities can be found in Note 6 to the accompanying consolidated financial statements.

Interest Rate Risk

At December 31, 2009, we had $825.6 million
in cash and cash equivalents as well as $40.0 million in short-term investments at December 31, 2009. Interest income earned on our cash investments is affected by changes in the relative levels of market interest rates. We only invest in
high-grade investment instruments. A hypothetical adverse 10% movement in market interest rates would decrease 2009 earnings by approximately $0.3 million.

Borrowings against lines of credit are at variable interest rates. We had insignificant amounts outstanding against our lines of credit at December 31, 2009. A hypothetical adverse 10% movement in
market interest rates would not have materially impacted our financial statements.

At December 31, 2009, we had $920.0
million in long-term debt, of which $275.0 million was, taking existing cash flow hedges into considerations, effectively at a variable rate. A hypothetical adverse 10% movement in market interest rates would decrease 2009 earnings by approximately
$0.3 million, based on the period-end interest rate.

Foreign Currency Exchange Rate Risk

As a global enterprise, we are subject to risks associated with fluctuations in foreign currencies with regard to our ordinary operations.
This includes foreign currency-denominated receivables, payables, debt, and other balance sheet positions as well as future cash flows resulting from anticipated transactions including intra-group transactions.

A significant portion of our revenues and expenses are earned and incurred in currencies other than the U.S. dollar. The euro is the most
significant such currency, with others including the British pound, Japanese yen, Swiss franc, and Canadian and Australian dollars. Fluctuations in the value of the currencies in which we conduct our business relative to the U.S. dollar have caused
and will continue to cause U.S. dollar translations of such currencies to vary from one period to another. Due to the number of currencies involved, the constantly changing currency exposures, and the potential substantial volatility of currency
exchange rates, we cannot predict the effect of exchange rate fluctuations upon future operating results. In general terms, depreciation of the U.S. dollar against our other foreign currencies will increase reported net sales. However, this effect
is, at least partially, offset by the fact, that we also incur substantial expenses in foreign currencies.

We have
significant production and manufacturing facilities located in Germany and Switzerland, and intercompany sales of inventory also expose us to foreign currency exchange rate risk. Intercompany sales of inventory are generally denominated in the local
currency of the subsidiary purchasing the inventory in order to centralize foreign currency risk with the manufacturing subsidiary. Payment for intercompany purchases of inventory is required within 30 days from invoice date. The delay between the
date the manufacturing subsidiaries record revenue and the date when the payment is received from the purchasing subsidiaries exposes us to foreign exchange risk. To the extent practicable, such exposures are offset by operational measures, which
include intercompany factoring transactions. We have entered into in the past, and may enter into in the future, foreign exchange derivatives, including forward contracts and options, to manage the remaining foreign exchange risk.

|Item 15. | Controls and Procedures
|-------- | -----------------------

Disclosure Controls and Procedures

Our Managing Directors, with the assistance of other members of management,
performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as that term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended, within 90 days of the
date of this report. Based on that evaluation, they concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is
recorded, processed, summarized and reported, within the time periods specified in the SECs rules and forms, and is accumulated and communicated to our management, including our Managing Directors, as appropriate to allow timely decisions
regarding required disclosure.

There are inherent limitations to the effectiveness of any system of disclosure controls and
procedures, no matter how well designed, such as the possibility of human error and the circumvention or overriding of the controls and procedures. Therefore, even those systems determined to be effective may not prevent or detect misstatements and
can provide only reasonable assurance of achieving their control objectives. In addition, any determination of effectiveness of controls is not a projection of any effectiveness of those controls to future periods, as those controls may become
inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate.

Report of Management on Internal Control over Financial Reporting

Our management is responsible for
establishing and maintaining adequate internal control over financial reporting as defined in Rules 13(a)-15(f) and 15(d)-15(f) under the Securities Exchange Act of 1934, as amended. The Companys system of internal controls over financial
reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements and even when
determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of the Companys internal control over financial reporting as of December 31, 2009. In making this assessment, management used the criteria set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on our assessment under the
COSO Internal Control-Integrated Framework, management believes that, as of December 31, 2009, our internal control over financial reporting is effective.Securities and Exchange Commission guidelines permit companies to exclude
acquisitions from their assessment of internal control over financial reporting during the first year following an acquisition.

|Item 16G. | Corporate Governance
|--------- | --------------------

Our
corporate governance practices generally derive from the provisions of the Dutch Civil Code and the Dutch Corporate Governance Code. Further, due to our listing at the German Stock Exchange in Frankfurt, the Managing Board and the Supervisory Board
of QIAGEN N.V. declared their intention to disclose in QIAGENs Annual Reports the Companys compliance with the German Corporate Governance Code adopted by the Government Commission on the German Corporate Governance Code pursuant to
§161 of the German Stock Corporation Law or state the deviations recorded in the period. These standards differ in some respects from the corporate governance practices followed by U.S. companies under the NASDAQ listing standards. A brief
summary of the principal differences follows.

Two-Tier Board

QIAGEN is a Naamloze Vennootschap, or N.V., a Dutch limited liability company similar to a corporation in the United States.
QIAGEN has a two-tier board structure. QIAGEN is managed by a Managing Board consisting of executive management acting under the supervision of a Supervisory Board (non executives), similar to a Board of Directors in a U.S. corporation. The Managing
Board manages QIAGEN and is responsible for defining and achieving QIAGENs aims, strategy, policies and results. The Managing Board is also responsible for complying with all relevant legislation and regulations as well as for managing the
risks associated with the business activities and the financing of QIAGEN. It reports related developments to and discusses the internal risk management and control systems with the Supervisory Board. The Managing Board is accountable for the
performance of its duties to the Supervisory Board and the General Meeting of Shareholders (General Meeting). The Managing Board consists of one or more members as determined by the Supervisory



82



---

##### Table of Contents

Board. The members of the Managing Board are appointed by the General Meeting upon the joint meeting of the Supervisory Board and the Managing Board having made a binding nomination for each
vacancy. However, the General Meeting may at all times overrule the binding nature of such a nomination by a resolution adopted by at least a two-thirds majority of the votes cast, if such majority represents more than half the issued share capital.
Managing Directors are appointed annually for the period beginning on the date following the General Meeting up to and including the date of the General Meeting held in the following fiscal year. The remuneration of management is determined in
accordance with a remuneration policy which has been approved by QIAGENs shareholders at the General Meeting on June 14, 2005. The remuneration of the members of the Managing Board will, with due observance of the remuneration policy, be
determined by the Supervisory Board based on a proposal by its Compensation Committee.

The Supervisory Board supervises the
policies of the Managing Board, the general course of QIAGENs affairs and the business enterprises which it operates. The Supervisory Board assists the Managing Board by providing advice relating to the business activities of QIAGEN. In
discharging its duties, the Supervisory Board takes into account the interests of QIAGEN, its enterprise and all parties involved in QIAGEN, including shareholders and other stakeholders.

Members of the Supervisory Board are appointed annually for the period beginning on the date following the General Meeting up to and
including the date of the General Meeting held in the following fiscal year. Members of the Supervisory Board may be suspended and dismissed by the General Meeting by a resolution adopted by a two-thirds majority of the votes cast, if such majority
represents more than half of the issued share capital, unless the proposal was made by the Managing Board and the Supervisory Board in which case a simple majority of votes cast is sufficient. Pursuant to our Articles, members of the
Supervisory Board cannot be involved in the day-to-day management of our business. Our Supervisory Board has specified matters requiring its approval, including decisions and actions which would fundamentally change the companys assets,
financial position or results of operations. The Supervisory Board has appointed an Audit Committee, a Compensation Committee and a Selection and Appointment (Nomination) Committee from among its members and can appoint other committees as deemed
beneficial. The Supervisory Board has approved charters pursuant to which each of the committees operates.

Independence

Unlike the NASDAQ listing standards which require a majority of the Supervisory Board members to be independent, the Dutch Corporate
Governance Code recommends that all Supervisory Board members, with the exception of not more than one person, shall be independent within the meaning of its best practice provision. In some cases the Dutch independence requirement is
more stringent, such as by requiring a longer look back period (five years) for former executive directors. In other cases, the NASDAQ rules are more stringent, such as a broader definition of disqualifying affiliations. Currently, a
majority of our Supervisory Board are independent under both the NASDAQ and Dutch definitions.

Independent Auditors

In contrast to rules applicable to U.S. companies, which require that external auditors be appointed by the Audit
Committee, Dutch law requires that external auditors be appointed by the General Meeting. In accordance with the requirements of Dutch law, the appointment and removal of our independent registered public auditor must be approved by the General
Meeting. The Supervisory Board nominates a candidate for the appointment as external auditor, for which purpose both the Audit Committee and the Managing Board advise the Supervisory Board. The remuneration of the external auditor, and instructions
to the external auditor to provide non-audit services, shall be approved by the Supervisory Board on the recommendation of the Audit Committee and after consultation with the Managing Board. At least once every four years, the Supervisory Board and
the Audit Committee shall conduct a thorough assessment of the functioning of the external auditor. The main conclusions

of this assessment shall be communicated to the General Meeting for the purposes of assessing the nomination for the appointment of the external auditor.

Exemptions

Exemptions
from the NASDAQ corporate governance standards are available to foreign private issuers, such as QIAGEN when those standards are contrary to a law, rule or regulation of any public authority exercising jurisdiction over such issuer or contrary to
generally accepted business practices in the issuers country of domicile. In connection with QIAGENs initial public offering, NASDAQ granted QIAGEN exemptions from certain corporate governance standards that are contrary to the laws,
rules, regulations or generally accepted business practices of The Netherlands. These exemptions and the practices followed by QIAGEN are described below:



| |  |  | QIAGEN is exempt from NASDAQs quorum requirements applicable to meetings of ordinary shareholders. In keeping with the law of The Netherlands and
generally accepted business practices in The Netherlands, QIAGENs Articles of Association provide that there are no quorum requirements generally applicable to meetings of the General Meeting.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | QIAGEN is exempt from NASDAQs requirements regarding the solicitation of proxies and provision of proxy statements for meetings of the General
Meeting. QIAGEN does furnish proxy statements and solicit proxies for meetings of shareholders. However, the laws of The Netherlands do not provide for a record date to be fixed in advance of a General Meeting. As a result, the holder of
the shares on the day of the meeting may vote the shares at the meeting. QIAGENs transfer agent has implemented procedures to check votes by proxy for validity on the day of the meeting.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | QIAGEN is exempt from NASDAQs requirements that shareholder approval be obtained prior to the establishment of, or material amendments to, stock
option or purchase plans and other equity compensation arrangements pursuant to which options or stock may be acquired by directors, officers, employees or consultants. QIAGEN is also exempt from NASDAQs requirements that shareholder approval
be obtained prior to certain issuances of stock resulting in a change of control, occurring in connection with acquisitions of stock or assets of another company or issued at a price less than the greater of book or market value other than in a
public offering. QIAGENs Articles of Association do not require approval of the General Meeting prior to the establishment of a stock plan. The Articles of Association also permit the General Meeting to grant the Supervisory Board general
authority to issue shares without further approval of the General Meeting. QIAGENs General Meeting has granted the Supervisory Board general authority to issue up to a maximum of our authorized capital without further approval of the General
Meeting. QIAGEN plans to seek approval of the General Meetings for stock plans and stock issuances only where required under the law of The Netherlands or under QIAGENs Articles of Association.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Supervisory Board and Shareholders of QIAGEN N.V. and Subsidiaries

We have audited the accompanying consolidated balance sheets of QIAGEN N.V. and Subsidiaries as of December 31, 2009 and 2008, and the
related consolidated statements of income, shareholders equity and comprehensive income and cash flows for each of the three years in the period ended December 31, 2009. Our audits also included the financial statement schedule listed in
the Index at Item 18A. These financial statements and schedule are the responsibility of the Companys management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the
financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects,
the consolidated financial position of QIAGEN N.V. and Subsidiaries at December 31, 2009 and 2008, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2009, in
conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects
the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), QIAGEN N.V. and Subsidiaries internal control over financial reporting as of December 31, 2009, based on criteria established in Internal ControlIntegrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission and our report dated March 16, 2010 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Supervisory Board and Shareholders of QIAGEN N.V. and Subsidiaries

We have audited QIAGEN N.V. and Subsidiaries internal control over financial reporting as of December 31, 2009, based on criteria
established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). QIAGEN N.V. and Subsidiaries management is responsible for maintaining effective
internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our
responsibility is to express an opinion on the companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective
internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating
the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management
and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.

In our opinion, QIAGEN N.V. and Subsidiaries maintained, in all material respects, effective internal control
over financial reporting as of December 31, 2009, based on the COSO criteria.

We have also audited, in accordance with
the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of QIAGEN N.V. and Subsidiaries as of December 31, 2009 and 2008, and the related consolidated statements of income,
shareholders equity and comprehensive income and cash flows for each of the three years in the period ended December 31, 2009 of QIAGEN N.V. and Subsidiaries and our report dated March 16, 2010 expressed an unqualified opinion
thereon.

DECEMBER 31, 2009



|1. | Description of Business
|-- | -----------------------

QIAGEN N.V., a Netherlands holding company, and subsidiaries (the Company) is a leading provider of innovative technologies and products for preanalytical sample preparation and linked molecular assay solutions. The Company has developed a
comprehensive portfolio of more than 500 proprietary, consumable products and automated solutions for sample collection, and nucleic acid and protein handling, separation, and purification as well as open and target-specific assays. The Company also
supplies diagnostic kits, tests, and assays for human and veterinary molecular diagnostics. Products are sold to academic research markets, to leading pharmaceutical and biotechnology companies, to applied testing customers (such as in forensics,
veterinary, biodefense and industrial applications) as well as to molecular diagnostics laboratories. In addition, the Company sells and/or licenses technologies to others. The Companys products are subject to rapid technological change.
Because of these technological changes, the Company needs to continuously expend resources toward research and development. Products are sold through a dedicated sales force and a global network of distributors in more than 40 countries.

Certain reclassifications of prior year amounts have been made to conform to the current year presentation, including reclassifications
related to the Companys adoption of the provisions of Accounting Standards Codification Topic 810, (formerly Statement of Financial Accounting Standards (SFAS) No. 160, Noncontrolling Interests in Consolidated Financial
Statements, an amendment of ARB No. 51).

On September 30, 2009, the Company completed an offering pursuant to
which QIAGEN N.V. sold an aggregate of 31.625 million common shares, including 4.125 million common shares upon exercise of the underwriters over-allotment option, at an offering price of $20.25/EUR 13.82 per common share for
aggregate gross proceeds of approximately $640.4 million. The Company received net proceeds from the offering of $623.6 million, after deducting $12.8 million of underwriting commissions and $4.0 million of offering expenses, net of related tax
benefits.

During 2009, the Company acquired DxS Ltd and SABiosciences Corporation. During 2008, the Company acquired Corbett
Life Science Pty. Ltd. and the assets related to the Biosystems Business from Biotage AB, as discussed more fully in Note 4. These acquisitions have been accounted for using the purchase method of accounting, and the acquired companies results
have been included in the accompanying financial statements from their respective dates of acquisition.



|2. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

Principles of Consolidation

The accompanying consolidated financial
statements were prepared in conformity with U.S. generally accepted accounting principles (GAAP) and include the accounts of the Company and its wholly owned subsidiaries other than those that are considered variable interest entities for which the
Company is not the primary beneficiary. All significant intercompany accounts and transactions have been eliminated. All amounts are presented in U.S. dollars, unless otherwise indicated. Investments in companies where the Company exercises
significant influence over the operations, and which the Company has determined that it is not the primary beneficiary, are accounted for using the equity method. All other investments are accounted for under the cost method.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management
to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingencies at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Concentrations of Risk

The Company buys materials for products from many suppliers, and is not dependent on any one supplier or group of suppliers for the business
as a whole. However, key components of certain products, including certain instrumentation components and chemicals, are available only from a single source. If supplies from these vendors were delayed or interrupted for any reason, the Company may
not be able to obtain these materials timely or in sufficient quantities in order to produce certain products and sales levels could be negatively affected. Additionally, the Companys customers include researchers at pharmaceutical and
biotechnology companies, academic institutions and government and private laboratories. Fluctuations in the research and development budgets of these researchers and their organizations for applications in which the Companys products are used
could have a significant effect on the demand for our products.

The financial instruments used in managing the Companys
foreign currency and interest rate exposures have an element of risk in that the counterparties may be unable to meet the terms of the agreements. The Company attempts to minimize this risk by limiting the counterparties to a diverse group of
highly-rated international financial institutions. The carrying values of the Companys financial instruments incorporate the non-performance risk by using market pricing for credit risk. However, the Company has no reason to believe that any
counterparties will default on their obligations and therefore does not expect to record any losses as a result of counterparty default. In order to minimize the Companys exposure with any single counterparty, the Company has entered into
master agreements which allow it to manage the exposure with the respective counterparty on a net basis. In connection with such agreements, the Company does not require and is not required to pledge collateral for derivative transactions.

Other financial instruments that potentially subject the Company to concentrations of credit risk are cash and cash
equivalents, short-term investments, and accounts receivable. The Company attempts to minimize the risks related to cash and cash equivalents and short-term investments by using highly-rated financial institutions that invest in a broad and diverse
range of financial instruments. The Company has established guidelines related to credit ratings and maturities of investments intended to maintain safety and liquidity. Concentration of credit risk with respect to accounts receivable is limited due
to a large and diverse customer base, which is dispersed over different geographic areas. Allowances are maintained for potential credit losses and such losses have historically been within expected ranges.

Fair Value of Financial Instruments

The carrying value of the Companys cash and cash equivalents, notes receivable, accounts receivable, accounts payable and accrued liabilities approximate their fair values because of the short
maturities of those instruments. The carrying value of the Companys variable rate debt and capital leases approximate their fair values because of the short maturities and/or interest rates which are comparable to those available to the
Company on similar terms. The fair values of the notes payable to QIAGEN Finance and Euro Finance, further discussed in Note 14, were estimated by using available over-the-counter market information on the convertible bonds which were issued by
QIAGEN Finance and Euro Finance, the values of which correlate to the fair value

QIAGEN N.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



of the loan arrangements the Company has with QIAGEN Finance and Euro Finance which includes the notes payable, the guarantee and the warrant agreement (further discussed in Note 10).

Cash and Cash Equivalents and Short-Term Investments

Cash and Cash Equivalents:    Cash and cash equivalents consist of cash on deposit in banks and other cash invested temporarily in various instruments that are short-term and
highly liquid, and having an original maturity of less than 90 days at the date of purchase.

Short-Term
Investments:    Short-term investments are classified as available for sale and stated at fair value in the accompanying balance sheet. Interest income is accrued when earned and changes in market values are
reflected as unrealized gains and losses, calculated on the specific identification method, as a component of accumulated other comprehensive income. A decline in fair value that is judged to be other-than-temporary is accounted for as a realized
loss and the write-down is included in the consolidated statements of income. Realized gains and losses, determined on a specific identification basis, on the sale of short-term investments are included in income.

Accounts Receivable

The Companys accounts receivable are unsecured and the Company is at risk to the extent such amounts become uncollectible. The Company continually monitors accounts receivable balances, and provides for an allowance for doubtful
accounts at the time collection becomes questionable based on payment history or age of the receivable. For the years ended December 31, 2009, 2008 and 2007, write-offs of accounts receivable totaled $0.6 million, $0.7 million and $1.1 million
while provisions for doubtful accounts which were charged to expense totaled $1.7 million, $0.8 million and $1.8 million, respectively. For all years presented, no single customer represented more than ten percent of accounts receivable or
consolidated net sales.

Inventories

Inventories are stated at the lower of cost, determined on a first-in, first-out basis, or market and include material, capitalized labor and overhead costs. Inventories consist of the following as of
December 31, 2009 and 2008:



|                  |  |                    |         |      |   |

|                  |  |                    |         |      |   |        
|Total inventories |  | $                  | 130,851 |      | $ | 108,563
|                  |  |                    |         |      |   |        

Property, Plant and Equipment

Property, plant and equipment, including equipment acquired under capital lease obligations, are stated at cost. Depreciation is computed
using the straight-line method over the estimated useful lives of the assets (one to 40 years). Amortization of leasehold improvements is computed on a straight-line basis over the lesser of the remaining life of the lease or the estimated useful
life. The Company has a policy of capitalizing expenditures that materially increase assets useful lives and charging ordinary maintenance and repairs to operations as



F-11

QIAGEN N.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



incurred. When property or equipment is disposed of, the cost and related accumulated depreciation and amortization are removed from the accounts and any gain or loss is included in other income
(expense).

Acquired Intangibles and Goodwill

Acquired intangibles are carried at cost less accumulated amortization and consist of licenses to technology held by third parties and other
intangible assets acquired by the Company. Amortization is computed over the estimated useful life of the underlying patents, which has historically ranged from one to twenty years. Purchased intangible assets other than goodwill are amortized over
their estimated useful lives unless these lives are determined to be indefinite. Intangibles are assessed for recoverability considering the contract life and the period of time over which the intangible will contribute to future cash flow. The
unamortized cost of intangible assets is evaluated periodically and adjusted, if necessary, if events and circumstances indicate that a permanent decline in value below the carrying amount has occurred.

Amortization expense related to developed technology and patent and license rights which have been acquired in a business combination is
included in cost of sales. Amortization of trademarks, customer base and non-compete agreements which have been acquired in a business combination is recorded in operating expense under the caption acquisition-related intangible
amortization. Amortization expenses of intangible assets not acquired in a business combination are recorded within either the cost of sales, research and development or sales and marketing line items based on the use of the asset.

Goodwill represents the difference between the purchase price and the estimated fair value of the net assets acquired
arising from business combinations. Goodwill is subject to impairment tests annually or earlier if indicators of potential impairment exist, using a fair-value-based approach. The Company has elected to perform its annual test for indications of
impairment as of October 1stof each year. Goodwill
is potentially impaired when, in the first step, the net book value of a reporting unit exceeds its estimated fair value. Our reporting units are our subsidiaries. If impairment is indicated, then the second step of the goodwill impairment test is
performed to measure the amount of the impairment loss, if any. In testing for potential impairment, the estimated fair value of reporting units is based upon discounted future operating cash flows using a discount rate reflecting the estimated
average cost of funds. Future cash flows are based on recent sales data for existing products, planned timing of new product launches or capital projects, and customer commitments related to new and existing products. These budgets also included
assumptions of future production volumes and pricing. Following the annual impairment tests for the years ended December 31, 2009, 2008 and 2007, goodwill has not been impaired.

Investments

The Company has investments in non-marketable securities issued by privately held companies. These investments are included in other long-term assets in the accompanying consolidated balance sheets and are accounted for using the equity or
cost method of accounting.

Investments are evaluated at least quarterly, or sooner if impairment indicators are noted, to
determine if declines in value are other-than-temporary. In making that determination, the Company considers all available evidence relating to the realizable value of a security. This evidence includes, but is not limited to, the following:



| |  |  | adverse financial conditions of a specific issuer, segment, industry, region or other variables;
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | the length of time and the extent to which the fair value has been less than cost; and
| | - |  | --------------------------------------------------------------------------------------



| |  |  | the financial condition and near-term prospects of the issuer.
| | - |  | --------------------------------------------------------------

QIAGEN N.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The fair values of any of the Companys equity method investments have declined
below their carrying value whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable. If any such decline is considered to be other than temporary (based on various factors, including historical
financial results, product development activities and the overall health of the affiliates industry), then a write-down of the investment would be recorded to its estimated fair value.

Long-Lived Assets

The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or a group of assets may not be recoverable. The Company considers a history of operating
losses or a change in expected sales levels to be indicators of potential impairment. Assets are grouped and evaluated for impairment at the lowest level for which there are identified cash flows that are largely independent of the cash flows of
other groups of assets. The Company deems an asset to be impaired if a forecast of undiscounted projected future operating cash flows directly related to the asset, including disposal value, if any, is less than its carrying amount. If an asset is
determined to be impaired, the loss is measured as the amount by which the carrying amount of the asset exceeds fair value. The Company generally measures fair value by discounting projected future cash flows. Considerable judgment is necessary to
estimate discounted future cash flows. Accordingly, actual results could differ from such estimates.

Revenue Recognition

The Companys revenues are reported net of sales and value added taxes, discounts and sales allowances, and are
derived primarily from the sale of consumable and instrumentation products, and to a much lesser extent, from the sale of services and technology. The Company recognizes revenue when four basic criteria are met: (1) persuasive evidence of an
arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is fixed and determinable; and (4) collectability is reasonably assured.

Consumable Products:Revenue from consumable product sales is generally recognized upon transfer of title
consistent with the shipping terms. Per the Companys usual shipping terms, title and risk of loss pass to the customer upon delivery of product to the shipping location. The Company maintains a small amount of consignment inventory at certain
customer locations. Revenues for the consumable products which are consigned in this manner are recognized upon consumption. The Company generally allows returns of consumable products if the product is returned in a timely manner and in good
condition. Allowances for returns are provided for based upon the historical pattern of returns and Managements evaluation of specific factors that impact the risk of returns.

Instrumentation:Revenue from instrumentation includes the instrumentation equipment, installation, training
and other instrumentation services, such as extended warranty services or product maintenance contracts. Revenue from instrumentation equipment is generally recognized when title passes to the customer, upon either shipment or written customer
acceptance after satisfying any installation and training requirements. For instrumentation equipment sales that contain other obligations, such as providing consumables, advanced training, separately-priced extended warranty services or
separately-priced extended maintenance contracts, revenue is first allocated to separately-priced extended warranty or maintenance contracts based on the stated contract price, then the remaining contract value is allocated to the remaining elements
based on objective, verifiable evidence of the fair value of the individual components. The price charged when the element is sold separately generally determines its fair value. Revenues for extended warranty services or extended product
maintenance contracts are deferred and recognized on a straight-line basis over the contract period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Other:Other revenue includes license fees, royalties and
milestone payments. License fees from research collaborations include payments for technology transfer and access rights. Non-refundable, up-front payments received in connection with collaborative research and development agreements are generally
deferred and recognized on a straight-line basis over the contract period during which there is any continuing obligation. Payments for milestones, generally based on the achievement of substantive and at-risk performance criteria, are recognized in
full at such time as the specified milestone has been achieved according to the terms of the agreement. Royalties from licensees are based on reported sales of licensed products and revenues are calculated based on contract terms when reported sales
are reliably measurable, fees are fixed and determinable and collectability is reasonably assured.

Research and
Development

Research and product development costs are expensed as incurred. Research and development expenses consist
primarily of salaries and related expenses, facility costs and amounts paid to contract research organizations, and laboratories for the provision of services and materials.

Shipping and Handling Income and Costs

Shipping and handling costs charged to customers are recorded as revenue in the period that the related product sale revenue is recorded. Associated costs of shipping and handling are included in sales
and marketing expenses. For the years ended December 31, 2009, 2008 and 2007, shipping and handling costs totaled $17.5 million, $17.1 million and $17.1 million, respectively.

Advertising Costs

The costs of advertising are expensed as incurred. Advertising costs for the years ended December 31, 2009, 2008 and 2007 were $10.6 million, $21.5 million and $5.0 million, respectively.

General and Administrative, Integration and Other

General and administrative expenses primarily represent the costs required to support administrative infrastructure. In addition, the Company incurs indirect acquisition and business integration costs in
connection with its purchase business combinations. These costs represent incremental costs that the Company believes would not have been incurred absent the business combinations. Major components of these costs include payroll and related costs
for employees remaining with the Company on a transitional basis; public relations, advertising and media costs for re-branding of the combined organization; and, consulting and related fees incurred to integrate or restructure the acquired
operations. Other costs include relocation and restructuring costs incurred in connection with a restructuring which was not contemplated at the time of acquisition. These costs are expensed as incurred.

Warranty

The Company warrants its products against defects in materials and workmanship generally for a period of one year. A provision for estimated future warranty costs is recorded at the time product revenue is recognized.

Income Taxes

The Company accounts for income taxes under the liability method. Under this method, total income tax expense is the amount of income taxes expected to be payable for the current year plus the change
from the beginning of the year for deferred income tax assets and liabilities established for the expected further tax consequences resulting from differences in the financial reporting and tax basis of assets and liabilities. Deferred tax assets
and/or liabilities are determined by multiplying the differences between the financial reporting and tax reporting bases for assets and liabilities by the enacted tax rates expected to be in effect when such differences are recovered or settled. The
effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date.

Tax
benefits are initially recognized in the financial statements when it is more likely than not that the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest
amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority, assuming full knowledge of the position and all relevant facts.

Foreign Currency Translation

The Companys functional currency is the U.S. dollar and subsidiaries functional currencies are the local currency of the respective countries in which they are headquartered. All amounts in
the financial statements of entities whose functional currency is not the U.S. dollar are translated into U.S. dollar equivalents at exchange rates as follows: (1) assets and liabilities at period-end rates, (2) income statement accounts
at average exchange rates for the period, and (3) components of shareholders equity at historical rates. Translation gains or losses are recorded in shareholders equity, and transaction gains and losses are reflected in net income.
Realized gains or losses on the value of financial contracts entered into to hedge the exchange rate exposure of receivables and payables are also included in net income. The net gain (loss) on foreign currency transactions in 2009, 2008 and 2007
was $5.6 million, ($0.2 million), and $2.0 million, respectively, and is included in other income, net.

Derivative
Instruments

The Company enters into derivative financial instrument contracts only for hedging purposes. The purpose of
the derivative instruments is to minimize the variability of cash flows or income statement impact associated



F-15

QIAGEN N.V. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



with the anticipated transactions being hedged or to hedge fluctuating interest rates. As changes in foreign currency or interest rate impact the value of anticipated transactions, the fair value
of the forward or swap contracts also changes, offsetting foreign currency or interest rate fluctuations. Derivative instruments are recorded on the balance sheet at fair value. Changes in fair value of derivatives are recorded in current earnings
or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction.

Share-Based
Payments

Compensation cost for all share-based payments is recorded based on the grant date fair value.

Stock Options:The Company utilizes the Black-Scholes-Merton valuation model for estimating the fair value of
its stock options granted. Option valuation models, including Black-Scholes-Merton, require the input of highly subjective assumptions, and changes in the assumptions used can materially affect the grant date fair value of an award. These
assumptions include the risk-free rate of interest, expected dividend yield, expected volatility, and the expected life of the award.

Risk-Free Interest RateThis is the average U.S. Treasury rate (having a term that most closely resembles the expected life of the option) at the date the option was granted.

Dividend YieldThe Company has never declared or paid dividends on its common stock and does not anticipate declaring or paying
any dividends in the foreseeable future.

Expected VolatilityVolatility is a measure of the amount by which a
financial variable such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company uses a combination of the historical volatility of its stock price and the implied
volatility of market-traded options of the Companys stock to estimate the expected volatility assumption input to the Black-Scholes-Merton model. The Companys decision to use a combination of historical and implied volatility is based
upon the availability of actively traded options of its stock and its assessment that such a combination is more representative of future expected stock price trends.

Expected Life of the OptionThis is the period of time that the options granted are expected to remain outstanding. The Company estimated the expected life by considering the historical
exercise behavior. The Company uses an even exercise methodology, which assumes that all vested, outstanding options are exercised uniformly over the balance of their contractual life.

Forfeiture RateThis is the estimated percentage of options granted that are expected to be forfeited or cancelled on an annual
basis before becoming fully vested. The Company estimated the forfeiture rate based on historical forfeiture experience.

Restricted Stock Units:Restricted stock units represent rights to receive Common Shares at a future date. The fair market value is determined based on the number of restricted stock units granted and the
market value of the Companys shares on the grant date. The fair market value at the time of the grant, less an estimate for pre-vesting forfeitures, is amortized to expense ratably over the vesting period.

September 30, 2009, the Company adopted the Financial Accounting Standards Board (FASB) Codification as outlined in Statement of Financial Accounting Standard (SFAS) 168, The FASB Accounting Standards CodificationTMand the Hierarchy of Generally Accepted Accounting Principles
(FASB ASC). The

Codification is now the source of authoritative U.S. GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the SEC under authority of federal
securities laws are also sources of authoritative GAAP for SEC registrants, as well as SEC Staff Accounting Bulletins. Effective for interim and annual periods ending after September 15, 2009, the Codification supersedes all then-existing
non-SEC accounting and reporting standards. All other nongrandfathered non-SEC accounting literature not included in the Codification will become nonauthoritative. FASB ASC Topic 105-10-65 Transition and Open Effective Date Information
identifies exceptions for FASB Statement Nos. 164 through 168, which will remain authoritative until these standards are incorporated into the Codification.

On June 30, 2009, the Company adopted SFAS 165 Subsequent Events. This standard provides general standards of accounting and disclosure to determine the period of time after the balance
sheet date in which events and transactions should be evaluated for disclosure, the circumstances under which events and transactions which occur after the balance sheet date should be recognized in the financial statements and disclosure guidance
on these events and transactions that occur after the balance sheet date.

On January 1, 2009, the Company adopted the
new provisions of FASB ASC Topic 805-20Business CombinationsIdentifiable Assets and Liabilities, and Any Noncontrolling Interest (formerly SFAS 141R and SFAS 160). These provisions impacted the Company primarily in five areas:
(1) acquired in-process research and development is now accounted for as an indefinite lived intangible asset until approval or discontinuation rather than as an expense; (2) acquisition costs are now expensed rather than added to the cost
of an acquisition; (3) restructuring costs in connection with an acquisition are now expensed rather than added to the cost of an acquisition; (4) the fair value of contingent consideration at the date of an acquisition is now included in
the cost of an acquisition; and (5) the fair value of contingent liabilities that are more likely than not to occur are now recorded at the date of an acquisition. The effects of these changes were applicable to acquisitions on or after
January 1, 2009. The Noncontrolling Interest provisions have been applied prospectively as of January 1, 2009, except for the presentation and disclosure requirements, which have been applied retrospectively for prior periods presented.
Prior to the adoption of the new provisions in FASB ASC Topic 805-20, the noncontrolling interests share of net income was included in minority interest in income (expense) in the consolidated statement of income, and the noncontrolling
interests equity was included outside of equity in the consolidated balance sheet.

On January 1, 2009, the Company
adopted the new disclosure provisions in FASB ASC Topic 815-10-50Derivatives and HedgingDisclosure (formerly SFAS 161). FASB ASC Topic 815-10-50 is intended to improve financial reporting about derivative instruments and hedging
activities by requiring enhanced disclosures to enable investors to better understand the effects of derivative instruments and hedging activities on an entitys financial condition, financial performance and cash flows. FASB ASC Topic
815-10-50 impacts disclosures only.

On January 1, 2009, the Company adopted the new provisions of FASB ASC Topic
808Collaborative Arrangements (specifically the provisions included in the former EITF Issue No. 07-1) that discuss how parties to a collaborative arrangement (which does not establish a legal entity within such arrangement) should
account for various activities. The provisions indicate that costs incurred and revenues generated from transactions with third parties (i.e., parties outside of the collaborative arrangement) should be reported by the collaborators on the
respective line items in their income statements pursuant to FASB ASC Topic 605-45Revenue Recognition Principle Agent Considerations (formerly under EITF Issue No. 99-19). Additionally, the provisions of FASB ASC Topic 808
provide that income statement characterization of payments between the participants in a collaborative arrangement should be based upon existing authoritative guidance; analogy to such pronouncements if not within their scope; or a reasonable,
rational, and consistently applied accounting policy

election. These provisions shall be applied retrospectively to all prior periods presented for all collaborative arrangements existing as of the effective date. The adoption of these provisions
did not result in a change to the Companys historical consolidated financial statements.

In 2009, there was an update
to FASB ASC Topic 320InvestmentsDebt and Equity Securities (formerly FSP FAS 115-2 and FAS 124-2), which provides additional guidance for the accounting for and presentation of impairment losses on securities. The Company adopted
these updates in the second quarter of 2009 without any impact.

In 2009, the FASB updated ASC Topic 820Fair Value
Measurements and Disclosures (formerly FSP FAS 157-4). This update emphasizes that even if there has been a significant decrease in the volume and level of activity for the asset or liability, fair value is still determined as the price that would
be received to sell an asset or paid to transfer a liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. The Company adopted
these updates in the second quarter of 2009 without any impact.

In 2009, the FASB updated ASC Topic 825Financial
Instruments (formerly FSP FAS 107-1 and APB 28-1). This update amends ASC Topic 825 to require disclosures about fair value of financial instruments for interim reporting periods of publicly-traded companies as well as in annual financial
statements. This update also amends ASC Topic 270Interim Reporting (formerly APB Opinion No. 28) to require these disclosures in summarized financial information at interim reporting periods. The Company adopted these updates in the
second quarter of 2009.

Recently Issued Accounting Standards

In October 2009, the FASB issued new authoritative guidance regarding Revenue RecognitionMultiple Deliverable Revenue
Arrangements.This update provides amendments for separating consideration in multiple deliverable arrangements and removes the objective-and-reliable-evidence-of-fair-value criterion from the separation criteria used to determine whether
an arrangement involving multiple deliverables contains more than one unit of accounting, replaces references to fair value with selling price to distinguish from the fair value measurements required under the Fair
Value Measurements and Disclosuresguidance, provides a hierarchy that entities must use to estimate the selling price, eliminates the use of the residual method for allocation, and expands the ongoing disclosure requirements. This update
is effective for the Company beginning January 1, 2011. The Company is evaluating the effect that adoption of this update will have, if any, on the consolidated financial position and results of operations.

In June 2009, the FASB issued SFAS 167, Amendments to FASB Interpretation No. 46(R). This standard amends older guidance in
ASC Topic 810Consolidation (formerly FIN 46(R)) by eliminating the quantitative-based risks and rewards calculation for determining which enterprise, if any, has a controlling financial interest in a variable interest entity. The standard
instead applies a qualitative approach that identifies which enterprise has the most significant impact on the variable interest entitys economic performance and which has (1) the obligation to absorb losses of the entity or (2) the
right to receive benefits from the entity. The standard also requires an additional reconsideration event when the equity holders of the entity, as a group, lose the power from voting rights or similar rights to direct the activities of the entity
that most significantly impact the entitys economic performance. Ongoing assessments of whether an enterprise is the primary beneficiary of a variable interest entity and expanded disclosures about an enterprises involvement in variable
interest entities will also be required. This standard is effective as of the beginning of each reporting entitys first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting
period and for interim and annual reporting periods thereafter. The Company adopted this standard on January 1, 2010 without any impact.

Significant 2009 Acquisitions

DxS Ltd. Acquisition

On September 21, 2009, the Company acquired 100% of the outstanding shares of DxS Ltd. (DxS), a privately-held
developer and manufacturer of companion diagnostic products headquartered in Manchester, United Kingdom. With this acquisition, the Company believes that it has taken a strong leadership position in personalized healthcare (PHC). The transaction is
valued at $94.5 million in cash, plus up to an additional $35.0 million in contingent consideration. The acquisition date fair value of the total consideration was $112.1 million, which consisted of $94.5 million in cash and $17.6 million for the
acquisition date fair value of the contingent consideration. The Company has deposited $9.1 million of the consideration in an escrow account with a paying agent to cover any claims for breach of any of representations, warranties, covenants or
indemnities or failure to satisfy certain conditions. This amount is included in prepaid expenses and other in the accompanying Consolidated Balance Sheet. Correspondingly, the Company has recorded preacquisition contingencies of $9.1 million which
are included in accrued and other liabilities in the accompanying Consolidated Balance Sheet.

The contingent consideration of
$35.0 million relates to specific commercial and other milestones, which, if met will be paid as follows: $10.0 million in 2010, $10.0 million in 2011, $2.5 million until November 30, 2011, $5.0 million until May 31, 2012, $5.0 million
until September 21, 2012 and $2.5 million until November 30, 2012. The preliminary total fair value of milestones is approximately $17.6 million which, as of the acquisition date, has been recognized as purchase price. The fair value of
the milestone payments was determined using a discount rate of 3.25% and a probability regarding the accomplishment of the milestones of 90 to 95%.

SABiosciences Acquisition

On December 14, 2009, the Company acquired
100% of the outstanding shares of SABiosciences Corporation, located in Frederick, Maryland (USA). SABiosciences holds a leading position in the design and commercialization of disease- and pathway-focused real-time PCR-based assay panels, which are
widely utilized in biomedical research and in the development of future drugs and diagnostics. At closing, the purchase price was

The weighted-average amortization period for the intangible assets acquired with DxS is 15 years and with
SABiosciences is 10 years. The goodwill acquired in these acquisitions is not deductible for tax purposes.

Pro forma
results

The following unaudited pro forma information assumes that the above acquisitions occurred at the beginning of
the periods presented. For the years ended December 31, 2009 and 2008, pro forma net sales would have been $1,049.1 million and $922.0 million, pro forma net income would have been $138.0 million and $87.6 million, and pro forma diluted net
income per common share would have been $0.65 and $0.43, respectively. These unaudited pro forma results are intended for informational purposes only and are not necessarily indicative of the results of operations that would have occurred had the
acquisitions been in effect at the beginning of the periods presented, or of future results of the combined operations.

Other 2009 Acquisitions

On August 6, 2009, the Company acquired Explera s.r.l., a leading supplier
in molecular diagnostics and personalized medicine in Italy. The transaction is valued at $7.5 million, with a fixed purchase price of $5.0 million and milestone payments of $2.5 million, which are expected to be realized. With this acquisition, the
Company is expanding the size of its molecular diagnostics sales channel in Italy and is adding several activities in the area of personalized medicine and access to a suite of CE-IVD pyrosequencing assays.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



On November 12, 2009, the Company acquired 100% of the outstanding shares of a
privately-held developer, producer and distributor of PCR-based technologies for forensics, kinship and paternity analysis, and other human identity testing applications located in Germany. Upon closing of the transaction, an upfront payment of
$23.3 million was paid to the sellers, less an amount of $13.1 million which is retained in an escrow account to cover any claims for breach of any of representations, warranties or indemnities. Another $1.5 million was paid to the sellers in the
beginning of January 2010.

The Companys acquisitions have historically been made at prices above the fair value of the
acquired net assets, resulting in goodwill, due to expectations of synergies of combining the businesses. These synergies include use of the Companys existing infrastructure, such as sales force, distribution channels and customer relations,
to expand sales of the acquired businesses products; use of the infrastructure of the acquired businesses to cost-effectively expand sales of Company products; and elimination of duplicative facilities, functions and staffing.

These acquisitions have been accounted for using the purchase method of accounting, and the acquired companies results have been
included in the accompanying statements of operations from their respective dates of acquisition. The allocation of the purchase price is preliminary and is based upon information that was available to management at the time the financial statements
were prepared. Accordingly, the allocation may change. The Company has gathered no information that indicates the final purchase price allocations will differ materially from the preliminary estimates other than for the final determination of the
intangible assets acquired with the acquisition of DxS and SABiosciences. Acquisition-related costs are expensed when incurred and are included in general, administrative, integration and other in the accompanying consolidated statements of income.

2008 Acquisitions

On July 1, 2008, the Company acquired an 82.5% interest in Corbett Life Science Pty. Ltd. (Corbett), a privately-held developer, manufacturer, and distributor of life sciences instrumentation
headquartered in Sydney, Australia, with an option to acquire the minority interest. On October 1, 2008, the Company acquired all assets related to the Biosystems Business from Biotage AB, a publicly listed developer, manufacturer and
distributor of products for genetic analysis and medicinal chemistry headquartered in Uppsala, Sweden. This business division contains Pyrosequencing systems for genetic analysis, PyroMark products for methylation, sequence and mutation
analysis and Pyro Gold reagents. Additionally, the transaction included the acquisition of Biotages 17.5% shareholding in Corbett.

The weighted-average amortization period for all intangible assets acquired in 2008 is 10 years. The
goodwill acquired in these acquisitions is not deductible for tax purposes.

Other 2008 Acquisitions

In 2008, the Company acquired a business unit from Diagnostic Technology Pty. Ltd., located in Belrose, Australia, which relates to the
distribution of products in Australia, New Zealand, Singapore and Malaysia. The purchase price consisted of an upfront payment in the amount of Australian dollars (AUD) 0.9 million and a milestone payment amounting to AUD 0.4 million,
which was paid in 2009. Additionally in 2008, the Company established QIAGEN Mexico via the acquisition of certain assets of the Companys former life science distributor Quimica Valaner. The Company also acquired the minority interest in its
Brazilian sub, QIAGEN Brasil Biotecnologia Ltda., for $3.2 million in cash in 2008. The establishment of QIAGEN Mexico, as well as the acquisition of the minority interest in its Brazilian subsidiary, represents the Companys commitment to
expanding its presence in Latin America. The Company does not consider these acquisitions to be material.

2009 Divestiture

In July 2009, through the sale of the Companys subsidiary in Austria, the Company sold the
Olerup SSP® product line and related assets to Olerup International AB, a subsidiary of LinkMed, a Swedish
venture capital

company specializing in life sciences. The Olerup SSP®
product line includes molecular transplantation testing products used for DNA human leukocyte antigen (HLA) typing. The Company retained rights to all Olerup SSP® assays for applications outside transplantation testing, such as in personalized medicine. The transaction does not affect the Companys presence in new
sequencing-based typing assays in the area of transplantation. The Company recorded a net gain of approximately $1.2 million on the sale of the business, which is recorded in other income, net in 2009.

2009 Restructuring of Acquired Business

In October 2009, the Company started the closure of its facilities and relocation of its activities in Brisbane and Sydney to other locations of the Company, primarily to QIAGEN Instruments AG in
Switzerland. These restructurings follow the acquisition of Corbett in 2008 and consolidate the Companys instrument manufacturing activities. The closure and relocation are expected to be completed in the second quarter of 2010 at a total
pre-tax cost of approximately $4.0 million to $5.0 million. During 2009, the Company had incurred approximately $2.3 million of restructuring costs, of which $1.6 million was accrued as of December 31, 2009.

|6. | Derivatives and Hedging and Fair Value Measurements
|-- | ---------------------------------------------------

Derivatives and Hedging

In the ordinary course of business, the Company
uses derivative instruments, including swaps, forwards and/or options, to manage potential losses from foreign currency exposures and variable rate debt. The principal objective of such derivative instruments is to minimize the risks and/or costs
associated with global financial and operating activities. The Company does not utilize derivative or other financial instruments for trading or other speculative purposes. The Company recognizes all derivatives as either assets or liabilities on
the balance sheet, measures those instruments at fair value and recognizes the change in fair value in earnings in the period of change, unless the derivative qualifies as an effective hedge that offsets certain exposures.

As of December 31, 2009, all derivatives that qualify for hedge accounting are cash-flow hedges. For derivative instruments that are
designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in



F-23

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the
assessment of effectiveness are recognized in current earnings. In 2009, the Company did not record any hedge ineffectiveness related to any cash-flow hedges in income (expense) and did not discontinue any cash-flow hedges. There are no expected
transactions which would result in a reclassification of amounts in other comprehensive income into earnings in the next 12 months. Derivatives, including those that are not designated as hedges, are classified in the operating section of the
consolidated statements of cash flows, in the same category as the related consolidated balance sheet account.

Foreign Currency
Derivatives

As a globally active enterprise, the Company is subject to risks associated with fluctuations in foreign
currencies in its ordinary operations. This includes foreign currency-denominated receivables, payables, debt, and other balance sheet positions. The Company manages balance sheet exposure on a group-wide basis primarily using foreign exchange
forward contracts and cross-currency swaps.

The Company has foreign currency forward contracts with an aggregate notional
amount of $44.0 million, which have been entered into in connection with the notes payable to QIAGEN Finance (see Note 14) and which qualify for hedge accounting as cash-flow hedges. The Company has determined that no ineffectiveness exists related
to these derivatives. However, the differences between spot and forward rates were excluded from the assessment of hedge effectiveness and included in interest income as it effectively constitutes the difference in the interest rates of the
respective currency pairs. The contracts mature in July 2011 and had fair market values at December 31, 2009 and 2008 of approximately $5.7 million and $3.1 million, respectively, which are included in other long-term liabilities in the
accompanying consolidated balance sheets.

In addition, the Company was party to cross-currency swaps which have been entered
into in connection with the notes payable to Euro Finance (see Note 14) and which qualified as cash-flow hedges with a notional amount of $120.0 million and $60.0 million as of December 31, 2009 and 2008, respectively, which mature in November
2012 and had fair market values of $16.7 million and $4.9 million at December 31, 2009 and 2008, respectively, which are included in other long-term liabilities in the accompanying consolidated balance sheets.

Undesignated Derivative Instruments

The Company is party to various foreign exchange forward and swap arrangements which had, at December 31, 2009, an aggregate notional value of approximately $200.1 million and fair values of $0.9
million and $7.7 million, which are included in other assets and other liabilities, respectively, and which expire at various dates through March 2010. The transactions have been entered into to offset the effects from short-term balance sheet
exposure to foreign currency exchange risk. Changes in the fair value of these arrangements have been recognized in other income, net.

The Company was party to various foreign exchange forward and swap arrangements which had, at December 31, 2008, an aggregate notional value of approximately $163.3 million and fair values of $0.3 million and $10.9 million, which are
included in other assets and other liabilities, respectively, and which expired at various dates through March 2009. The transactions have been used to offset the effects from short-term balance sheet exposure to foreign currency exchange risk.
Changes in the fair value of these arrangements have been recognized in other income, net.

Interest Rate Derivatives

The Company uses interest rate derivative contracts on certain borrowing transactions to hedge fluctuating interest rates. The Company has
entered into interest rate swaps in which it agrees to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed-upon notional principal amount. During 2008, the Company entered
into interest rate swaps, which effectively fix the variable interest rates on $200.0 million of the Companys variable rate debt and qualify for hedge accounting as cash-flow hedges. The Company has determined that no ineffectiveness exists
related to these swaps. The swaps mature in October 2010 and 2011, and as of December 31, 2009 had an aggregate fair value of $6.3 million, of which $2.1 million is recorded in accrued and other liabilities and $4.2 million is recorded in other
long-term liabilities in the accompanying consolidated balance sheet. As of December 31, 2008 these swaps had an aggregate fair value of $6.8 million recorded in other long-term liabilities in the accompanying consolidated balance sheet.

Fair Value Measurements

The Companys assets and liabilities are measured at fair value according to a three-tier fair value hierarchy which prioritizes the
inputs used in measuring fair value as follows:

Level 1.Observable inputs, such as quoted prices in
active markets;

Level 2.Inputs, other than the quoted price in active markets, that are observable
either directly or indirectly; and

Level 3.Unobservable inputs in which there is little or no market
data, which require the reporting entity to develop its own assumptions.

The Companys assets and liabilities measured
at fair value on a recurring basis consist of short-term investments, which are classified in Level 1 of the fair value hierarchy, and derivative contracts used to hedge currency and interest rate risk, which are classified in Level 2 of the fair
value hierarchy and are shown in the table above. In determining fair value, both the counterparty credit risk and the Companys creditworthiness are considered. To determine the Companys credit risk we estimated the Companys credit
rating by benchmarking the price of outstanding debt to publicly-available comparable data from rated companies. Using the estimated rating, the Companys credit risk was quantified by reference to publicly-traded debt with a corresponding
rating.

The following table presents the Companys fair value hierarchy for its financial assets and liabilities
measured at fair value on a recurring basis as of December 31, 2009:

|10. | Investments
|--- | -----------

The Company
has made strategic investments in certain companies that are accounted for using the equity or cost method of accounting. The method of accounting for an investment depends on the level of the Companys influence. The Company monitors changes
in circumstances that may require a reassessment of the level of influence. The Company periodically reviews the carrying value of these investments for impairment, considering factors such as the most recent stock transactions and book values from
the recent financial

statements. The fair value of cost-method investments is estimated when there are identified events or changes in circumstances that may have an impact on the fair value of the investment.

A summary of these investments, which are included in other assets, is as follows:

During 2009, the
Company sold its investment in a privately-held company which had been accounted for under the cost-method of accounting, and realized a gain of $10.5 million. The proceeds were received in January 2010.

During 2008, in connection with the acquisition of Corbett, the Company impaired its $4.0 million investment in a privately-held company
which had been accounted for under the cost-method of accounting. Following the acquisition of Corbett, management anticipated a change in the Companys purchasing pattern of the investees products, which negatively impacted the
forecasted financial condition of the investee. Accordingly, the known impact to the investees financial condition, absent other evidence indicating a realizable value of the investment, indicates that the Companys investment was
worthless and that recoverability of the asset through future cash flows was not considered likely enough to support the current carrying value. The Company had no contractual obligation to provide any additional investment or other financing beyond
its present investment in the investee. The impairment is included in other income, net in the accompanying consolidated statements of income.

At December 31, 2009 and 2008, the Company had a loan receivable of $1.4 million included in other long-term assets, due from Dx Assays, which bears interest at 15% and is due in March 2013. As of
December 31, 2009 and 2008, total assets of Dx Assays totaled $5.0 million and $4.9 million, respectively, and shareholders equity amounted to $0.3 million and $0.2 million, respectively. In 2009 and 2008, Dx Assays recorded revenues of
$2.2 million and $0.1 million, respectively.

As of December 31, 2009 and 2008, total assets of QBM Cell Science totaled
$0.4 million and $0.2 million, respectively, and shareholders equity amounted to $0.4 million, and $0.2 million, respectively. In 2009 and 2008, QBM Cell Science recorded revenues of $0.4 million and $0.3 million respectively. In 2009, QBM
Cell Science recorded net income of $19,000 and in 2008 recorded a net loss of $0.3 million.

The Company has a 50% interest
in a joint venture company, PreAnalytiX GmbH, for which the Company is not the primary beneficiary. Thus, the investment is accounted for under the equity method. PreAnalytiX was formed to develop, manufacture and market integrated systems for the
collection, stabilization and purification of nucleic acids for molecular diagnostic testing. At present, the Companys maximum exposure to loss as a result of its involvement with PreAnalytiX is limited to the Companys share of losses
from the equity method investment itself. Total assets of PreAnalytiX amounted to $20.8 million and $16.4 million as of December 31, 2009 and 2008, respectively. The shareholders equity for PreAnalytiX amounted to $19.6 million and $15.9
million as of December 31, 2009 and 2008, respectively. PreAnalytiX revenues totaled $10.7 million and $10.2

million in 2009 and 2008, respectively. PreAnalytiX net income was $5.1 million and $3.9 million in 2009 and 2008, respectively.

The Company has a 100% interest in QIAGEN Finance (Luxembourg) S.A. (QIAGEN Finance) and QIAGEN Euro Finance (Luxembourg) S.A. (Euro
Finance), companies established for the purpose of issuing convertible debt in 2004 and 2006, respectively. In August 2004, the Company issued $150.0 million of 1.5% Senior Convertible Notes (2004 Notes) due in 2024 through QIAGEN Finance. In May
2006, the Company completed the offering of $300.0 million of 3.25% Senior Convertible Notes (2006 Notes) due in 2026 through Euro Finance. The proceeds of the 2004 and 2006 Notes were loaned to subsidiaries within the consolidated QIAGEN N.V.
group. QIAGEN N.V. has guaranteed all of these Notes, and has agreements with each of QIAGEN Finance and Euro Finance to issue common shares to the investors in the event of conversion of any of the Notes. QIAGEN Finance and Euro Finance are
variable interest entities. The Company is not the primary beneficiary, therefore neither is consolidated. Accordingly, the 2004 and 2006 convertible debt is not included in the consolidated statements of QIAGEN N.V., though QIAGEN N.V. does report
the full obligation of the debt through its liabilities to QIAGEN Finance and Euro Finance. QIAGEN N.V. accounts for its investments in QIAGEN Finance and Euro Finance as equity investments and accordingly records 100% of the profit or loss of
QIAGEN Finance and Euro Finance in the gain or loss from equity method investees. At present, the Companys maximum exposure to loss as a result of its involvement with QIAGEN Finance and Euro Finance is limited to the Companys share of
losses from the equity method investments.

The changes in the carrying amount of goodwill during the year ended December 31, 2009 resulted from
the 2009 acquisitions, foreign currency translation and purchase price adjustments primarily related to tax matters in connection with prior year acquisitions. During 2009, following the corporate restructuring of subsidiaries acquired in connection
with the Digene acquisition in 2007, goodwill was allocated to the remaining operating subsidiaries. Additionally, during 2009, an impairment loss of $1.6 million of goodwill from a previous acquisition was recognized following the Companys
acquisition of DxS Ltd. in September 2009. The goodwill impairment loss is related to the Germany segment and is recorded in general and administrative, integration and other expenses in the accompanying consolidated statements of income.

The Company conducts business globally and, as a result, files numerous consolidated and separate income tax
returns in The Netherlands, Germany, Switzerland and the U.S. federal jurisdiction, as well as in various other state and foreign jurisdictions. The Company has one tax holiday which expires in 2011. In the normal course of business, the Company is
subject to examination by taxing authorities throughout the world. The Companys tax years since 2002 are open for income tax examinations by tax authorities. Its subsidiaries, with few exceptions, are no longer subject to income tax
examinations by tax authorities for years before 2004.

On January 1, 2007, the Company adopted FASB Accounting Standards

considering the impact of adopting ASC 740, the Company had an approximate $12.6 million reserve for uncertain tax positions as of January 1, 2007. The reserve for uncertain income tax positions is included in taxes payable in the consolidated
balance sheets.

The Company does not currently anticipate that its existing reserves related to uncertain tax positions as of
December 31, 2009 will significantly increase or decrease during the twelve-month period ending December 31, 2010; however, various events could cause the Companys current expectations to change in the future. The majority of these
uncertain tax positions, if ever recognized in the financial statements, would be recorded in the statement of operations as part of the income tax provision.

Changes in the gross amount of unrecognized tax benefits are as follows:

At December 31, 2009 and December 31, 2008, the Companys net unrecognized tax benefits
totaled approximately $9.6 million and $7.7 million, respectively. At December 31, 2009, $9.6 million, if recognized, would favorably affect the Companys effective tax rate in any future period. It is possible that approximately $0.7
million of the unrecognized tax benefits may be released during the next 12 months due to lapse of statute of limitations or settlements with tax authorities.

The Companys policy is to recognize interest accrued related to unrecognized tax benefits in interest expense and penalties within tax provision expense. At December 31, 2009, the Company has
$0.5 million of accrued interest included in accrued and other liabilities in the accompanying consolidated balance sheet. During 2009, the amount of accrued interest increased by $0.1 million with approximately $30,000 of interest income and $0.2
million of interest expense recognized during 2009.

At December 31, 2009, the Company had $66.0 million of U.S. federal net operating loss (NOL)
carryforwards. These amounts include $9.4 million related to deductions for equity awards. These NOLs have, for the most part, been acquired in recent acquisitions and a portion of these NOLs are subject to limitations under Section 382 of the
Internal Revenue Code. As of December 31, 2009 and 2008, the Company had other foreign carryforwards totaling approximately $45.6 million and $36.4 million, respectively. These NOLs were primarily generated from acquisitions and operating
losses from the Companys subsidiaries. A portion of these NOLs, approximately $34.3 million at December 31, 2009, expire in various years through 2021. The balance does not expire. Our foreign NOLs are predominately reduced by
a full valuation allowance. The valuation allowance amounts to $15.6 million and $17.3 million for the years ended December 31, 2009 and 2008, respectively. The valuation allowance decreased by $1.7 million during 2009 and $2.2 million of that
decrease was triggered by an intercompany sale of assets with the gain and related tax affects eliminated in consolidation. Thus, $0.8 million was recognized as tax expense in 2009.

The Company has undistributed earnings in foreign subsidiaries. Upon repatriation of those earnings, in the form of dividends or otherwise,
in some jurisdictions, the Company would be subject to withholding taxes

payable to the foreign countries or the receipts would be subject to tax. For those subsidiaries where the earnings are considered to be permanently reinvested, no provision for taxes has been
provided. At December 31, 2009 and 2008, the Company had deferred income tax liabilities of approximately $0.9 million and $0.6 million, respectively, for taxes that would be payable on the unremitted earnings of certain subsidiaries of the
Company. Determination of the amount of unrecognized deferred tax liability on those unremitted earnings is not practicable because of the complexities associated with this hypothetical calculation.

There are no income tax consequences for the Company regarding payment of dividends to the shareholders of the Company. To date, the Company
has never paid dividends.

|--- | ------------------------

The Company has eleven separate lines of credit amounting to $183.7 million in the aggregate with variable interest rates, $0.9 million of which was utilized at December 31, 2009. There were no significant short-term borrowings as of
December 31, 2009 and 2008.

At December 31, 2009, total debt was approximately $920.0 million, $50.0 million of
which is current. Total debt consists of the following:

Interest expense on long-term debt was $26.7 million,
$33.7 million and $29.7 million for the years ended December 31, 2009, 2008 and 2007, respectively.

During 2007, the
Company signed a Syndicated Multi-Currency Term Loan and Revolving Credit Facilities Agreement with Deutsche Bank AG, Deutsche Bank Luxembourg S.A., and the lenders named in the agreement. The lenders made available to the Company an aggregate
amount of $750 million in the form of a $500 million term loan, a $100 million bridge loan, and a $150 million revolving credit facility. Under the agreement, the $500 million term loan will mature in July 2012 with an amortization
schedule commencing July 2009. In July 2009, $25.0 million was repaid. The $100 million bridge loan was utilized and repaid within the third quarter of 2007. The $150 million revolving credit facility will expire in July 2012. The proceeds of the
debt were loaned to a subsidiary of QIAGEN N.V., and QIAGEN N.V. has guaranteed the debt. The loan agreements contain certain financial and non-financial covenants, including but not limited to, restrictions on the encumbrance of land, restrictions
on the transfer of any patents to third parties and the maintenance of certain financial ratios. The Company was in compliance with these covenants at December 31, 2009.

In May 2006, the Company completed the offering of the 2006 Notes due in 2026 through a new unconsolidated subsidiary, Euro Finance. The net
proceeds of the 2006 Notes were loaned by Euro Finance to consolidated subsidiaries of the Company. At December 31, 2009 and 2008, $300.0 million is included in long-term debt for the amount of 2006 Note proceeds payable to Euro Finance. These
long-term notes payable to Euro Finance have an effective fixed interest rate of 3.91% and are due in November 2012. Interest on the 2006 Notes is payable semi-annually in May and November. The 2006 Notes were issued at 100% of principal value, and
are convertible into 15.0 million common shares at the option of the holders upon the occurrence of certain events, at a price of $20.00 per share, subject to adjustment. QIAGEN N.V. has an agreement with Euro Finance to issue shares to the
investors in the event of conversion. This subscription right, along with the related receivable, is recorded at fair value in the equity of QIAGEN N.V. as paid-in capital. The 2006 Notes cannot be called for the first 7 years and are callable
thereafter subject to a provisional call trigger of 130% of the conversion price. In addition, the holders of the 2006 Notes may require QIAGEN to repurchase all or a portion of the outstanding Notes for 100% of the principal amount, plus accrued
interest, on May 16, 2013, 2017 and 2022. Based on an estimation using available over-the-counter market information on the convertible bond issued by QIAGEN Euro Finance, the fair value of the Notes at December 31, 2009 was approximately
$387.3 million. The Company has reserved 15.0 million common shares for issuance in the event of conversion.

In August
2004, the Company completed the sale of the 2004 Notes, through its unconsolidated subsidiary QIAGEN Finance. The net proceeds of the 2004 Notes were loaned by QIAGEN Finance to consolidated subsidiaries in the U.S. and Switzerland. At
December 31, 2009 and 2008, $145.0 million is included in long-term debt for the amount of 2004 Note proceeds payable to QIAGEN Finance. In November 2008, $5.0 million was repaid in connection with the conversion of a portion of the 2004 Notes
issued by QIAGEN Finance. These long-term notes payable to QIAGEN Finance have an effective fixed interest rate of 2.14% and are due in July 2011. Interest on the 2004 Notes is payable semi-annually in February and August. The 2004 Notes were issued

to adjustment. QIAGEN N.V. has an agreement with QIAGEN Finance to issue shares to the investors in the event of conversion. This subscription right, along with the related receivable, is recorded at fair value in the equity of QIAGEN N.V. as
paid-in capital. In November 2008, the Company issued 395,417 common shares upon the exercise of a portion of the subscription rights in connection the conversion of $5.0 million of the 2004 Notes. The 2004 Notes may be redeemed, in whole or in
part, at QIAGENs option on or after August 18, 2011, at 100% of the principal amount, provided that the actual trading price of the Companys common stock exceeds 120% of the conversion price for twenty consecutive trading days. In

issuance in the event of conversion.



|15. | Share-Based Compensation
|--- | ------------------------

The Company adopted the QIAGEN N.V. Amended and Restated 2005 Stock Plan (the Plan) in 2005. The Plan allows for the granting of stock rights and incentive stock options, as well as non-qualified options, stock grants and stock-based
awards, generally with terms of up to 10 years, subject to earlier termination in certain situations. Generally, options vest over a three-year period. The vesting and exercisability of certain stock rights will be accelerated in the event of a
Change of Control, as defined in the Plan. To date, all option grants have been at the market value on the grant date or at a premium above the closing market price on the grant date. The Company issues new common shares to satisfy option exercises
and had approximately 15.5 million common shares reserved and available for issuance under this plan at December 31, 2009.

In connection with the acquisition of Digene Corporation during the third quarter of 2007, the Company assumed three additional equity incentive plans. No new grants will be made under these plans. The Company had approximately
0.4 million common shares reserved and available for issuance under these plans at December 31, 2009.

Generally, stock option grants are valued as a single
award with a single average expected term and are amortized over the vesting period. The weighted-average grant-date fair value of options granted during the years ended December 31, 2009, 2008 and 2007 was $6.33, $7.80 and $6.97, respectively.
The total intrinsic value of options exercised during the years ended December 31, 2009 and 2008 was $16.7 million and $14.9 million, respectively. At December 31, 2009, the unrecognized share-based compensation expense related to employee
stock option awards is approximately $3.3 million and will be recognized over a weighted average period of approximately 1.74 years.

At December 31, 2009, 2008 and 2007, options were exercisable with respect to 7.4 million, 9.6 million and 10.9 million Common Shares at a weighted average price of $14.36, $13.91 and $13.49 per share, respectively. The
options outstanding at December 31, 2009 expire in various years through 2019.

Restricted Stock Units

Restricted stock units represent rights to receive Common Shares at a future date. There is no exercise price and the fair market value at
the time of the grant is recognized ratably over the requisite vesting period, generally 10 years. The fair market value is determined based on the number of restricted stock units granted and the market value of the Companys shares on the
grant date. Pre-vesting forfeitures were estimated to be approximately 6.3%. At December 31, 2009, there was $36.9 million remaining in unrecognized compensation cost related to these awards, which is expected to be recognized over a weighted
average period of 8.6 years. The weighted average grant date fair value of restricted stock units granted during the year ended December 31, 2009 was $16.96. The total fair value of restricted stock units released during the years ended
December 31, 2009 and 2008 was $6.9 million and $10.3 million, respectively.

Licensing and Purchase Commitments

The Company has licensing agreements with companies, universities and individuals, some of which require certain up-front payments. Royalty
payments are required on net product sales ranging from one to 25 percent of covered products or based on quantities sold. Several of these agreements have minimum royalty requirements. The accompanying consolidated financial statements include
accrued royalties relating to these agreements in the amount of $18.3 million and $16.6 million at December 31, 2009 and 2008, respectively. Royalty expense relating to these agreements amounted to $47.2 million, $45.6 million, and $37.1
million for the years ended December 31, 2009, 2008 and 2007, respectively. Royalty expense is primarily recorded in cost of sales, with a small portion recorded as research and development expense depending on the use of the technology under
license. Some of these agreements also have minimum raw material purchase requirements and requirements to perform specific types of research.

At December 31, 2009, the Company had commitments to purchase goods or services, and for future minimum guaranteed royalties. They are as follows:

the achievement of certain revenue and operating results milestones as follows: $18.6 million in 2010, $16.5 million in 2011, $16.2 million in 2012 and $54.9 million payable in any 12 month
period from now until 2014 if certain criteria are met. Of the $106.2 million total contingent obligation, approximately $40.8 million is accrued as of December 31, 2009.

Employment Agreements

Certain of our employment contracts contain provisions which guarantee the payments of certain amounts in the event of a change in control, as defined in the agreements, or if the executive is terminated
for reasons other than cause, as defined in the agreements. At December 31, 2009, the commitment under these agreements totaled $18.9 million.

Contingencies

In the ordinary course of business, the Company warrants to
customers that its products are free of defect and will conform to published specifications. Generally, the applicable product warranty period is one year from the date of delivery of the product to the customer or of site acceptance, if required.
Additionally, the Company typically provides limited warranties with respect to its services. From time to time, the Company also makes other warranties to customers, including warranties that its products are manufactured in accordance with
applicable laws and not in violation of third-party rights. The Company provides for estimated warranty costs at the time of the product sale. The Company believes its warranty reserves as of December 31, 2009 and 2008 appropriately reflect the
estimated cost of such warranty obligations.

Preacquistion Contingencies

In connection with the 2009 and 2008 acquisitions, amounts were paid into escrow accounts to cover preacquistion contingencies assumed in the
acquisitions. The escrow amounts expected to be claimed by QIAGEN are recorded as an asset in prepaid and other expenses and amount to $37.1 million and $25.1 million as of December 31, 2009 and 2008, respectively. In addition, the Company has
recorded $40.8 million and $25.1 million for preacquistion contingencies as a liability under accrued and other liabilities as of December 31, 2009 and 2008, respectively.

Litigation

From time to time, QIAGEN may be party to legal proceedings incidental to its business. As of December 31, 2009, certain claims, suits or legal proceedings arising out of the normal course of business have been filed or were pending
against QIAGEN or its subsidiaries. These matters have arisen in the ordinary course and conduct of business, as well as through acquisition. As a result of the third quarter 2007 acquisition of Digene and the third quarter 2008 acquisition of
Corbett, QIAGEN is now involved in various claims and legal proceedings, including those related to protection of its owned and licensed intellectual property. Although it is not possible to predict the outcome of such litigation, based on the facts
known to QIAGEN and after consultation with legal counsel, management believes that such litigation will not have a material adverse effect on QIAGENs financial position or results of operations.

Digene Corporation v. F. Hoffmann-LaRoche Ltd. and Roche Molecular Systems, Inc.

In December 2006, Digene filed for arbitration with the International Centre for Dispute Resolution of the American Arbitration Association

Systems, Inc. (collectively Roche) for breach of contract of a 1990 Cross License Agreement between Digene and Roche for rights to certain HPV patents. Digene alleged that Roche had breached this
license agreement by entering into a Supply and Purchase Agreement with Gen-Probe, Inc. (Gen-Probe) in violation of the terms of the Cross License Agreement. On July 13, 2007, the arbitration panel granted Gen-Probes request to intervene
as a respondent in the arbitration. On April 1, 2009, the arbitration panel granted an interim award denying QIAGENs breach of contract claims and consequently also the damages. On April 15, 2009, Roche and Gen-Probe filed motions
for reimbursement of attorneys fees. On August 12, 2009, the arbitration panel issued a total award of $6.3 million, including administrative and arbitrator fees and on August 13, 2009, the Company filed a petition in the Supreme
Court of the State of New York to vacate or modify the award of the arbitrators. On August 20, 2009, Roche and Gen-Probe filed a joint petition to confirm the award, and on September 23, 2009, the Court set the briefing/hearing schedule.
On December 18, 2009, the District Court heard oral arguments on the petitions to vacate and confirm the arbitration award. The Courts ruling in currently pending. QIAGEN will vigorously pursue this matter.

Corbett v. Montreal Biotechnologies, Inc.

On February 19, 2009, M.H. Montreal Biotechnologies, Inc. (MBI) sued QIAGEN, Inc. and Corbett in the Circuit Court for Montgomery County, Maryland, seeking monetary damages. MBI claims that QIAGEN,
Inc. intentionally interfered with MBIs contractual relations with Corbett, intentionally interfered with MBIs contractual and business relations with its customers, and engaged in unfair competition. Separately, MBI contends that
Corbett breached its contract with MBI, breached the implied covenant of good faith and fair dealing, and also engaged in unfair competition. In a court hearing on October 14, 2009, the court dismissed the case against Corbett. MBI amended its
complain on November 16, 2009, adding QIAGEN N.V. and QIAGEN GmbH as new defendants and changing certain contentions against QIAGEN. QIAGEN will remain a defendant in these proceedings and will vigorously defend the matter.

QIAGEN Sciences, Inc. v. Operon Biotechnologies, Inc.

On July 2, 2009, Operon Biotechnologies, Inc. (Operon) commenced arbitration against QIAGEN Sciences, Inc. asserting a breach of a
supply agreement between the parties and is seeking monetary damages. Operon asserts that QIAGEN failed to comply with the preferred supplier provisions of the agreement and that this breach has caused damages, including lost profits. QIAGEN is in
the process of responding to this claim and will vigorously defend against the claim.

QIAGEN Gaithersburg, Inc. v.
Abbott GmbH & Co. KG.

On November 4, 2009, QIAGEN Gaithersburg, Inc. filed a patent infringement lawsuit
against Abbott GmbH & Co. KG (Abbott) in the Dusseldorf District Court in Germany moving for injunctive relief as well as declaratory judgment on damages with respect to patent infringement. On January 19, 2010, a case
management conference took place before the Dusseldorf District Court during which Abbott moved for dismissal of the complaint, and the Court set a due date of May 18, 2010 for Abbotts statement of defense, with
the Companys reply due by September 21, 2010, and Abbotts rejoinder due December 27, 2010. The hearing date is set for January 18, 2011. In reaction to the Dusseldorf lawsuit, Abbott has filed a motion to compel
arbitration, including an anti-suit injunction against QIAGEN before the Northern District Court of Illinois. QIAGEN filed its opposition on March 8, 2010. An oral hearing is scheduled for April 20, 2010. QIAGEN will vigorously
pursue this matter.

|17. | Employee Benefit Plans
|--- | ----------------------

The Company maintains various benefit plans, including defined contribution and defined benefit plans. The Companys U.S. defined contribution plan is qualified under Section 401(k) of the Internal Revenue Code, and covers
substantially all U.S. employees. Participants may contribute a portion of their compensation not exceeding a limit set annually by the Internal Revenue Service. This plan includes a provision for the Company to match a portion of employee
contributions. Total expense under the 401(k) plans, including the plans acquired via business acquisitions, was $2.0 million, $2.2 million and $1.4 million for the years ended December 31, 2009, 2008 and 2007, respectively. The Company also
has a defined contribution plan which covers certain executives. The Company makes matching contributions up to an established maximum. Matching contributions to the plan totaled approximately $0.4 million in each year ended December 31, 2009,
2008 and 2007.

The Company has four defined benefit, non-contributory retirement or termination plans that cover certain
employees in Germany, France, Japan and Italy. These defined benefit plans provide benefits to covered individuals satisfying certain age and service requirements. For certain plans, the Company calculates the vested benefits to which employees are
entitled if they separate immediately. The benefits accrued on a pro-rata basis during the employees employment period are based on the individuals salaries, adjusted for inflation. The liability under the defined benefit plans was
$2.1 million at December 31, 2009 and $2.9 million at December 31, 2008.

|19. | Segment and Related Information
|--- | -------------------------------

Reportable segments are based on the geographic locations of the subsidiaries. The Companys reportable segments include the Companys production, manufacturing and sales facilities located throughout the world. In addition, the
Companys corporate segment includes its holding company located in The Netherlands and two subsidiaries located in Germany which operate only in a corporate support function. The reportable segments derive revenues from the Companys
entire product and service offerings. It is not practicable to provide a detail of revenues for each group of similar products and services offered by the Company. The accounting policies of the segments are the same as those described in the
summary of significant accounting policies in Note 2 of the Notes to Consolidated Financial Statements. Summarized financial information concerning the Companys reportable segments is shown in the tables below.

Net sales are attributed to countries based on the location of the Companys subsidiary generating the sale. QIAGEN operates
manufacturing facilities in Germany, Switzerland, China, Australia, the United Kingdom and the United States that supply products to other countries. The sales from these manufacturing operations to other countries are included in the Net Sales of
the countries in which the manufacturing locations are based. The intercompany portions of such net sales of a reportable segment are excluded through the intersegment elimination to derive consolidated net sales. No single customer represents more
than ten percent of consolidated net sales.

On February 11, 2010, Roche Molecular Systems filed a lawsuit against DxS in the federal court for the Southern District of New York.
In its lawsuit, Roche alleges that DxS is preparing to terminate the parties Distributor Agreement without good cause and that DxS termination of the Agreement would cause Roche to suffer irreparable harm in the form of lost business
opportunities and goodwill and damage to Roches reputation. In connection with its lawsuit, Roche has also filed a motion for preliminary injunction in which it asks the court to issue an order prohibiting DxS from terminating the Agreement
and requiring DxS to perform its obligations under the Agreement pending the final resolution of the lawsuit. DxS filed its opposition to Roches motion on March 5, 2010, and the hearing on the motion is scheduled for March 22, 2010.
Given the early stage of this litigation, QIAGEN cannot predict the likely outcome and intends to vigorously pursue this matter.
