ITEM 1.     BUSINESS

Summary

We develop, manufacture and market our M-SERIES® family of products, which can serve as a platform for diagnostic systems to be used for the detection and measurement of biological or chemical substances. We incorporate our technologies into our instrument systems, tests and reagents, which are the biological and chemical components used to perform such tests. Using the M-SERIES platform, we intend to integrate technologies and products to develop small, expandable and modular systems that can perform a wide variety of immunodiagnostic and nucleic acid tests.

Our products are designed to be sold in the worldwide diagnostics markets, including:

2

We believe that the emergence of simple, more accurate and cost-effective clinical diagnostic products is shifting the site of clinical diagnostic testing from clinical reference laboratories and central hospital laboratories to decentralized patient care centers, such as physicians’ offices, ambulatory clinics, hospital emergency rooms, surgical and intensive care units, hospital satellite laboratories and nurses’ stations, which are collectively referred to as clinical point-of-care sites.

Our own product development efforts are focused on M-SERIES instruments and tests for the biodefense market and for the clinical diagnostics market, particularly for point-of-care sites. We are seeking to develop, market and sell products for the clinical point-of-care market segment through a combination of direct efforts and collaborative arrangements. We also are pursuing opportunities in the clinical reference laboratory and central hospital laboratory market segments through collaborative arrangements.

The first clinical diagnostic system being developed by us is an M-SERIES clinical analyzer that builds on the M-SERIES instruments we sell in the biodefense and life science markets. We are developing the assays using, among other things, improvements licensed from an affiliate of Roche. We believe that these improvements will reduce product development timelines. We also believe that the clinical analyzer will provide results to a physician rapidly with the same levels of sensitivity, accuracy or consistency as a large instrument in a clinical reference laboratory or in a central laboratory, thereby permitting the physician to make a more timely decision regarding the patient’s course of treatment. We will seek approval from the FDA for the clinical analyzer and other in vitro diagnostics products at the appropriate stage of their product development.

Our M-SERIES instruments are already being used in biodefense programs for homeland security, including by the Department of Defense, or DOD. We believe there will be an increasing opportunity to sell our products for biodefense tools by governmental and military organizations around the world, as well as in public health. We are also selling two types of M-SERIES instruments for life science research to pharmaceutical and biotechnology researchers, as well as to scientists at academic and government research institutions.

On February 13, 2004, IGEN and Roche consummated a merger and certain related transactions, which we refer to in this Form 10-K as the merger and related transactions, pursuant to which Roche acquired IGEN and IGEN simultaneously distributed shares of our common stock to its stockholders. The transaction occurred in the following steps:

Our Strategy

Our strategy is based on the direct development and sale of products utilizing our technologies, while at the same time entering into collaborations with third parties that can assist us in product development, manufacturing and marketing efforts. Key elements of our strategy are to:

Our Technology

Our M-SERIES family of products will incorporate a number of technologies, including:

ECL Technology

ECL technology is a technology based on electrochemiluminescence that is protected by patents in the United States and internationally.

ECL technology permits the detection and measurement of a biological or chemical substance within a given sample. It works by labeling the targeted substance within a sample using a compound and binding the newly labeled substance to magnetizable beads. The beads can then be separated from the rest of the sample using a magnet. When this newly labeled substance is stimulated, the label emits light at a particular wavelength.

The light emitted by the label can be measured with a high degree of accuracy. The level of intensity of the light emitted by the label is determined by the amount of the targeted biological substance present in the sample for the label to attach itself to. Thus, the light emissions permit the accurate detection and measurement of the targeted biological or chemical substance.

ECL technology provides a uniform format that can be used to conduct a multitude of tests, including immunodiagnostic tests and nucleic acid tests. The essential component of an ECL technology-based system is the flow cell, which contains a magnet to separate the labeled substance from the sample being tested and a light detector to measure the electrochemiluminescence.

4

The flow cell has been designed so that it can be incorporated into a variety of instruments, ranging from large central laboratory random access systems to small batch systems.

We believe that the major features and benefits of ECL technology-based systems are:

We believe that ECL technology is well suited for the continued development and sale of the M-SERIES family of instruments that can be used in all of our target diagnostic markets. We believe the technology will permit virtually all immunodiagnostic and nucleic acid tests to be performed on similar instrumentation using the same detection method.

ECL technology is well established in the market, evidenced by the fact that our licensees have developed multiple product lines based on ECL technology and have sold or placed over 10,000 systems with customers worldwide which generate over $500 million in annual sales. Substantially all of these sales and placements have been made by Roche, one of the world’s leading providers of clinical diagnostic products, which has a worldwide, non-exclusive, royalty-free license for our ECL technology for use with certain defined systems and immunoassay methods for the clinical diagnostics market. There can be no assurance that we will succeed in profitably developing, marketing and selling products based on ECL technology.

Improvements from Roche

As part of the merger and related transactions, we have acquired from Roche Diagnostics and its affiliates an irrevocable, worldwide, non-exclusive, fully-paid, royalty-free, perpetual license under certain patents covering technologies based on:

5

The license, which we refer to in this Form 10-K as the improvements license agreement may be used without a field restriction (except as set forth in the next sentence) to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or service based on ECL technology. In addition, we are licensed to use certain intellectual property rights of Hitachi High Technology Corporation and its affiliates only outside the field defined in the improvements license agreement to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or services based on ECL technology. Subject to an exception, the field in the improvements license agreement is the same as the field in the license agreement. We may sublicense rights under both of these licenses to affiliates and third parties.

The improvements license agreement does not permit us to develop, use, manufacture, sell or otherwise commercialize instruments based on ECL technology that meet certain specifications and use specific intellectual property, in the field. In addition, the license does not permit us to develop, use, manufacture or sell ECL assays that contain labeling that make them useable on ECL instruments manufactured, sold or placed by Roche Diagnostics or its licenses or resellers, in the field.

PCR Technology

PCR technology includes the amplification of specific nucleic acid sequences to a sufficient quantity of the nucleic acid sequence to permit detection and quantification. The process of nucleic acid amplification is commonly used for diagnostic procedures involving infectious agents, such as the AIDS virus, because of the need to detect the smallest amount of virus possible in the blood or other clinical samples.

The PCR license agreements obtained by us from Roche Diagnostics and its affiliates, which we refer to in this Form 10-K as the PCR license agreements, will allow us to develop nucleic acid tests for several specified markets, including the human and animal in vitro diagnostics markets. We believe that nucleic acid tests are currently one of the fastest growing segments of the clinical diagnostics market and would complement our immunodiagnostic product line. We do not currently sell, or have under development, any product based on the PCR technology being licensed from Roche. For more information about the license fee and royalty payments in connection with the PCR license agreements, see ITEM 8-“Consolidated Financial Statements-Notes to Consolidated Financial Statements-Note 1”.

Roche has advised us that Applied Biosystems has notified Roche that one or more of the PCR licenses granted by certain Roche affiliates to us under the improvements license agreement and the PCR license agreements may infringe exclusive rights to PCR technology held by, or other contract rights of, Applied Biosystems. Applied Biosystems has commenced litigation and arbitration against Roche regarding their respective rights relating to PCR technology. Certain Roche affiliates have made certain representations and provided certain warranties on their right to grant the licenses that have been granted to us, including representations and warranties that: the rights and licenses granted under the improvements license agreement and the performance by Roche Diagnostics of its obligations under the improvements license agreement will not conflict with any agreement, contract or other arrangement to which it is a party or by which it is bound; Roche Diagnostics has title to or license rights sufficient to grant such license rights granted under the improvements license agreement to us and our affiliates; Roche Diagnostics has not licensed or otherwise disposed of such licensed intellectual property rights in any manner that limits our or our affiliates’ exploitation of the licenses granted by Roche Diagnostics under the improvements license agreement; certain Roche affiliates have the full power and right to grant to us and our affiliates the licenses granted under the PCR license agreements; and the execution by certain Roche affiliates of the PCR license agreements will not constitute a breach or default under any contract, instrument or agreement to which such Roche affiliates or any of their affiliates are a party or by which such Roche affiliates or any of their affiliates are bound.

Roche has advised us that it believes that Applied Biosystems’ allegations are without merit and intends to contest them vigorously. There are no assurances that we will not be named as a defendant in either of those actions or that Roche will prevail in the litigation and arbitration, or that the terms of any resolution or settlement of these proceedings will not be unfavorable to us.

6

The results of these legal proceedings may limit, preclude or interfere with our ability to exploit certain PCR technology licensed under the improvements license agreement and PCR license agreements. See “Risk Factors — Risks Relating to Our Business — Because we intend to develop products that are based on patents and technology that we have licensed from others, the owners of those patents and technology might claim that products developed or sold by us violate those licenses. Additionally, a third party might object to a license that we hold or to the scope of the license granted to us.”

Unit Dose Cartridge Technology

We have a unique technology utilizing a disposable unit dose cartridge that we expect will be inexpensive to manufacture and contains all the reagents necessary to perform several different immunoassays on a single sample of blood from a patient. These reagents will be packaged so that they remain stable at room temperature for several months. This method of packaging reagents differs from the typical method of packaging reagents in a container that holds reagents for 100 to 200 tests for a single type of immunoassay and usually must be refrigerated. We have demonstrated that the test results using the unit dose cartridge are accurate and consistent with the results obtained using conventional instruments and kits used in central hospital laboratories. We believe the ease of use, room temperature stability, accuracy and consistency of test results associated with this technology are important features for use in clinical point-of-care sites and biodefense applications.

Products and Markets Using Our Technology

The following table summarizes the range of products that we have developed and are developing using our ECL technology. We expect that our future products will incorporate other technology, which may include the improvements from Roche, PCR technology and unit dose cartridge technology.

The following table summarizes the range of products that our licensees have developed using our ECL technology. In general, we will receive royalties or other payments as a result of product sales by our licensees other than Roche and MSD during the time we are a class A member of MSD. For a description of the commercial arrangements and license agreements that we have with our licensees see “Business-Collaborations and License Arrangements”.

Our Products and Markets

Clinical Diagnostics

We plan to manufacture and sell products utilizing our technologies for the clinical in vitro diagnostics market. In vitro diagnostic testing, which is the process of analyzing blood, urine and other samples to screen for, monitor and diagnose diseases and other medical conditions or to determine the chemical and microbiological constituents of the samples is one type of testing used by the clinical diagnostics market. We believe that ECL technology is best suited for the blood-based immunodiagnostic and nucleic acid testing segments of the clinical diagnostics market. The immunodiagnostic market segment was estimated to have had approximately $6 billion in annual sales in 2002. The nucleic acid testing market segment was estimated to have had approximately $1.5 billion in annual sales in 2001. Clinical diagnostic testing is performed in many locations, including testing by clinical reference laboratories, central hospital laboratories, and blood banks, as well as testing at clinical point-of-care sites. Our products for the clinical in vitro diagnostics market will generally require approval or clearance by the FDA prior to the marketing of the products, which we will seek in the appropriate stage of product development. See “Business — Government Regulation — Clinical Diagnostic Products” for a more detailed description of the government regulations to which we are subject in connection with products for the clinical in vitro diagnostics market.

Point-of-Care Systems. Many diagnostic tests performed today involve a follow-up treatment decision by the physician, but the test and treatment process are usually decoupled. In most situations, samples of blood are drawn from a patient in the physician’s office, emergency room or hospital room and sent to a laboratory at another location where the tests are performed. Test results are returned to the physician several hours or even several days later. We believe that there is demand among physicians, patients and third-party payers for clinical diagnostic products that reduce turnaround time by bringing laboratory testing closer to the patient and providing the physician with fast, quality and cost-effective results thereby permitting the physician to deliver prompt feedback to the patient.

Most immunodiagnostic systems for clinical point-of-care sites have had limited market penetration because of the lengthy turnaround time for test results, the need for skilled labor to perform the tests and the high cost of the tests. We believe that the emergence of simple, more accurate and cost-effective diagnostic products is

8

shifting the site of in vitro diagnostic testing from clinical reference laboratories and central hospital laboratories to alternative sites.

We are developing a new instrument system, a clinical analyzer that would be a part of our M-SERIES family of instruments. We plan to integrate ECL, PCR, and other technologies into a small, expandable and modular system for the performance of immunodiagnostic and nucleic acid tests. The clinical analyzer is being designed for ease of use and the ability to provide fast results and is expected to be marketed to clinical point-of-care sites bringing laboratory testing closer to the patient thereby providing the associated benefits described above. We believe that the clinical analyzer may also be used in clinical reference laboratories, central hospital laboratories, and blood banks, which presently constitute the majority of the clinical diagnostics market.

Currently available immunoassay tests for use at the clinical point-of-care sites are often not as sensitive, accurate, or consistent as similar tests run in a central laboratory. We believe the clinical analyzer can provide rapid turn-around time with the same levels of sensitivity, accuracy and consistency as a large instrument in a clinical reference laboratory or a hospital central laboratory.

We are exploring collaborative business arrangements to accelerate the development, manufacture and marketing of ECL technology-based products for clinical point-of-care applications.

Clinical/Reference and Central Hospital Laboratory Systems. One of the significant applications of ECL technology is in large, highly automated clinical immunodiagnostic systems used in clinical reference laboratories, central hospital laboratories and blood banks. These laboratories currently constitute the vast majority of the clinical diagnostics market. To serve these laboratories, systems must be able to perform a wide variety of immunodiagnostic tests on a large number of samples consistently, cost effectively and quickly. Although we do not currently manufacture or sell products for the clinical diagnostics market, we intend to pursue opportunities for the clinical reference and central hospital laboratory market segment through collaborative arrangements.

Non-Clinical Diagnostics

Biodefense. We are commercializing products in the emerging market segment for biodefense, which involves the detection of bacteria, viruses and toxins that may pose a military or public health threat, as well as for the detection of foodborne and waterborne disease causing pathogens. Our currently available instruments include the BIOVERIS Detection System and the M-SERIES M1R and M1M instruments. We believe there will be an increasing opportunity to use our products as a biodefense tool in governmental and military organizations around the world, as well as in public health, due to the early adoption of our products by key decision makers. We believe there currently are no dominant competitors. We expect that our nonclinical products for biodefense will generally not require the approval of a U.S. government agency prior to marketing of the products. See “Business — Government Regulation — Biodefense and Industrial Testing Products” for a more detailed description of the government regulations to which we are subject in connection with our products for biodefense.

U.S. Army scientists at Fort Detrick, Maryland have developed ECL technology-based biological tests designed to measure specific agents and toxins in environmental samples. We have a contract with the DOD pursuant to which the DOD may purchase these tests from us. Under the contract, the DOD may, at its option, make purchases of up to $23.0 million over a period of up to 48 months through June 2007. As of March 31, 2004, the DOD had purchased approximately $3.4 million of products under the contract. The tests are used by various laboratories and field sites of the DOD, as well as other U.S. government agencies. For risks related to our contracts with the government see “Risk Factors — Risks Relating to Regulation and Government Contracts.”

In June 2004, we introduced for sale our new M-SERIES M1M Analyzer which is specifically designed to function in demanding field environments, as well as in the laboratory. The M1M is an automated analyzer designed for use with our BioVerify™ test kits for the detection of botulinum neurotoxins, anthrax, ricin, and

9

staphylococcal enterotoxins A and B, among others. The analyzer has also been designed for use with the tests currently being manufactured by us for the DOD.

The system has easy-to-use sample handling and can detect biological agents quickly and with high sensitivity. System software reports positive or negative results automatically in a standard format. The M1M Analyzer was built with specification and configuration inputs from our customers and is designed to meet the needs of field, mobile and centralized laboratories.

We also plan to develop an additional M-SERIES instrument that can be both miniaturized and “ruggedized” for use primarily by soldiers; “first responders,” such as fire, police and emergency medical workers; medical workers; hospitals; food processors; field inspectors from the Environmental Protection Agency, or the EPA, the Department of Agriculture, or the Food and Drug Administration, or the FDA; and border patrol inspectors.

We expect to continue to work with the DOD and other U.S. government agencies to expand the use of ECL technology-based products in a variety of homeland security and biodefense initiatives, including the development of reagents for the detection of biological agents, such as anthrax, staphylococcus enterotoxin B and botulinum, or toxins in environmental samples.

The Automated Biological Agent Testing System program at the Edgewood Chemical and Biological Center, Aberdeen Proving Ground, in conjunction with us and Beckman Coulter, has integrated an M-SERIES instrument system with Beckman Coulter’s SAGIAN™ and Biomek® FX lab automation systems to automate sample preparation and plate handling for ECL technology-based immunoassays. This program is designed for high throughput detection of biological agents and incorporates reagents that are being manufactured by us. We are also engaged in early-stage initiatives for product development for this market including:

Certain of our U.S. government contracts contain provisions that grant to the U.S. government a non-exclusive, non-transferable, irrevocable, paid-up license to use inventions made by us in the course of performing such contracts, or have such inventions used by or on behalf of the U.S. government, for research or other government purposes. See “Risk Factors — Risks Relating to Regulation and Government Contracts.”

Our presence in the biodefense market also provides the opportunity to sell products to other diagnostics markets. In addition to manufacturing specific tests for the detection of biological agents or toxins for the DOD, we have developed our own line of tests that can be sold to the pharmaceutical, biotechnology and food industries. These products include tests for the detection of botulinum toxins A, B, E and F, staphylococcal enterotoxins A and B, ricin and anthrax. We intend to expand this product line to meet the demands of the market. We believe that tests developed for the biodefense field may also have utility in the clinical diagnostic markets by providing tests for patients exposed to biological agents or toxins.

Industrial. We manufacture and sell a panel of tests for the detection of foodborne and waterborne disease-causing pathogens, such as E. coli O157, Salmonella, Campylobacter and Listeria. These tests are used as a quality control method for testing food and beverage products, such as meat used in hamburger, for bacteria that have caused numerous outbreaks of gastrointestinal and kidney-related disease worldwide.

We expect that our products for industrial testing will generally not require the approval of a U.S. government agency prior to marketing of the products. See “Business — Government Regulation — Biodefense and Industrial Testing Products” for a more detailed description of the government regulations to which we are subject in connection with our products for industrial testing.

10

Life Science. We provide products and services for the discovery and development of new drugs to the life science market. Our product development and marketing efforts center on two M-SERIES instruments — the M384 and the M1R instruments — each of which build on the ECL technology-based applications provided by the M-SERIES systems and the BIOVERIS Detection System.

Our products can be used by pharmaceutical and biotechnology companies, universities and other research organizations in most phases of drug discovery, including:

After identifying disease targets and synthesizing chemical compounds, researchers attempt to find compounds that are drug candidates. This drug discovery process involves developing an assay to determine whether a particular compound has the desired effect on a target and then screening compounds using that assay. We believe that the need of pharmaceutical and biotechnology companies to rapidly identify therapeutic targets, screen thousands of compounds per day against those targets and then optimize the leads has created new opportunities for ECL technology-based systems in the pharmaceutical and biotechnology industry. Our M-SERIES instruments are compatible with multi-well microplates that are commonly used in drug discovery and development laboratories and can be fully integrated with many existing automation and robotic systems. These instruments were designed to enable researchers to test new biological targets against potential drug compounds with higher levels of accuracy and sensitivity. We believe they may also perform highly sensitive tests more quickly at a lower cost and this may permit a drug candidate to move more rapidly into the later stages of drug development, clinical trials and ultimately into the market.

We believe that the sensitivity and accuracy of these M-SERIES systems create advantages over many competitive detection technologies. They permit the user to:

Our expertise in developing assays allows us to assist customers in determining whether a proposed assay is feasible and to assist with the development and performance of assays that comply fully with the FDA’s Good Manufacturing Practices.

Our M-SERIES life science customers include many of the major pharmaceutical and biotechnology companies in the United States and Europe. In addition to the M-SERIES instruments we sell or lease, we typically receive commitments from customers for purchases of proprietary reagents. We market the M-SERIES product family directly through our own sales, marketing and applications teams. Instrument systems originally designed for the life science market are now being used in biodefense and may be used in the clinical diagnostics market as well. We believe that our presence in the life science market provides us with the opportunity to identify novel tests that may have utility in the clinical diagnostics market.

11

While continuing to support our existing bio-pharmaceutical and academic customers, we may selectively pursue other commercial opportunities in the life science or other markets in support of our overall corporate strategy. Our products that will be sold only for research use in the life science market generally do not require the approval of a U.S. government agency prior to marketing of the products. See “Business — Government Regulation — Life Science Research Products” for a more detailed description of the government regulations to which we are subject in connection with our products for the life science market.

Collaborations and License Arrangements

We expect to explore and negotiate collaborative business arrangements to accelerate the development, manufacture and marketing of ECL technology-based products, in particular into the clinical diagnostics market. In addition, we have license arrangements with Roche Diagnostics, bioMérieux, Eisai and MSD.

Roche Diagnostics

In connection with the merger and related transactions, Roche, one of the world’s leading providers of clinical diagnostic products, has obtained a worldwide, royalty-free, non-exclusive license, which we refer to in this Form 10-K as the license agreement, to develop, make, reproduce, modify, use, sell and otherwise commercially exploit certain clinical immunoassay instruments and assays using defined ECL technology owned by us in the human in vitro diagnostics field, including the continued sale and further development of its Elecsys products. We will not receive royalties or other payments as a result of product sales by Roche in accordance with the license agreement.

Under the improvements license agreement with Roche, we have a worldwide, non-exclusive, fully-paid, royalty-free, perpetual license under certain patents covering and technologies based on:

In addition, we are licensed to use certain intellectual property rights of Hitachi High Technology Corporation and its affiliates only outside the field defined in the improvements license agreement to develop, make, reproduce, modify, use, sell and otherwise commercially exploit any product or service based on ECL technology.

bioMérieux

bioMérieux, Inc., or bioMérieux, has a license from us for the development and worldwide development, use, manufacture and sale of ECL technology-based nucleic acid test systems on a co-exclusive basis for certain segments of the clinical diagnostics market and on a non-exclusive basis for certain segments of the life science market. bioMérieux specializes in products for central hospital laboratories and blood banks and has incorporated its proprietary nucleic acid sequence-based amplification technology and ECL technology into its NucliSens line of diagnostic virology products, which are marketed with test kits for the detection of HIV-1 RNA and CMV (cytomegalovirus). The agreement with bioMérieux extends until the expiration of the patents we license to bioMérieux, and we receive royalty payments from bioMérieux on the relevant product sales by bioMérieux.

Eisai

12

Eisai Co., Ltd., or Eisai, a leading Japanese pharmaceutical company, has a license to manufacture and market a class of ECL technology-based diagnostic systems for the clinical diagnostics market in Japan on a non-exclusive basis. Eisai introduced its first ECL-based product under the trade name Picolumi in 1997. We receive royalties on the relevant product sales by Eisai. The agreement with Eisai extends until the later of May 10, 2010, and the expiration of the patents we license to Eisai. Eisai is obligated to make royalty payments to us at a reduced royalty rate for a period of seven years after expiration of the agreement.

MSD

As part of the merger and related transactions, we assumed IGEN’s interest in MSD, a joint venture formed in 1995 by IGEN and Meso Scale Technologies, LLC., or MST, which is a company established and wholly-owned by Mr. Jacob Wohlstadter, a son of our chief executive officer. An independent committee of IGEN’s board of directors, with the advice of independent advisors and counsel, negotiated and approved the MSD agreements. MSD develops, manufactures, markets and sells products utilizing a combination of MST’s multi-array technology and our technology. MSD manufactures, markets and sells instrument systems, including the Sector HTS and the Sector PR, which combine MST’s multi-array technology and our ECL technology.

The Sector HTS is an ultra high throughput drug discovery system engineered for applications such as high throughput screening and large-scale proteomics. The Sector PR is a smaller system designed for benchtop applications such as assay development, research in therapeutic areas, cellular biology and medium throughput screening. MSD also manufactures and markets a line of its own reagents, assays and plates that are used on these MSD systems. During the year ended December 31, 2003, MSD had revenues of $7.7 million and a net loss of $20.4 million.

The joint venture agreement among MSD, MST and us, which we refer to in the Form 10-K as the MSD joint venture agreement, expired upon completion of the merger and related transactions. As a result, MSD and MST had the right to purchase our interest in MSD. Pursuant to the settlement agreement we entered into with MSD, MST and Jacob Wohlstadter in August 2004, which is referred to in this Form 10-K as the settlement, MSD or MST will purchase and we will sell, our entire interest in MSD. For a more complete description of this purchase right and the MSD agreements, see ITEM 13 — “Certain Relationships and Related Transactions”.

In June and July 2004, we commenced legal actions against MSD, MST and Jacob Wohlstadter in the Court of Chancery in the State of Delaware that were prompted by the discovery of a series of actual and proposed transactions undertaken by MSD without our knowledge. These litigations were settled in August 2004 pursuant to the settlement. See ITEM 3 — “Legal Proceedings” for a more complete description of these litigations and the related settlement.

Patents and Other Proprietary Rights

We pursue a policy of seeking patent protection to preserve our technology and our right to capitalize on the results of our research and development activities and, to the extent it may be necessary or advisable, to exclude others from appropriating our technology. We will also rely on trade secrets, know-how, continuing technological innovations and licensing opportunities to develop and maintain our competitive position.

We intend to prosecute and defend our intellectual property, including our patents, trade secrets and know-how. We plan to regularly search for third-party patents in our fields of endeavor, both to shape our patent strategy as effectively as possible and to identify possible collaborations and licensing opportunities.

We own approximately 71 issued U.S. patents, and approximately 28 pending U.S. patent applications in the diagnostics field. Additionally, we own approximately 158 granted foreign patents and approximately 65 pending foreign patent applications in the diagnostics field. These patents and patent applications are important to our business and cover various aspects of ECL technology and products, as well as the methods for their production and use.

13

The pending patent applications in the diagnostics field may not be granted and others may challenge our patents. Our ECL patents will begin to expire in 2005; however, patent coverage for ECL technology will continue through 2018. We plan to continue to protect our technology with new patent filings, which could further extend our patent coverage.

Our business could be harmed if we lose our patent protection or if pending patents are not issued to us.

The research and development, manufacturing, marketing, sale and distribution of both existing and future products based on ECL technology are subject to comprehensive government regulation. Government regulation by various Federal, state, and local agencies, which includes detailed inspection of, and controls over, research and laboratory procedures, safety, clinical investigations, manufacturing, marketing, sampling, labeling, distribution, record keeping, storage and disposal practices, substantially increases the time, difficulty and costs incurred in obtaining and maintaining the clearance or approval to market newly developed and existing products. In particular, government regulatory actions can result in, among other things, delays in the release of our and our licensees’ products, injunction, seizure or recall of our or our licensees’ products, suspension or revocation of the authority necessary for their production and sale, and other civil or criminal sanctions, including monetary penalties that could be substantial.

International sales of products by us and our licensees will also be subject to a significant degree of government regulation, including international standards (such as those set by the International Organization for Standards), European Union directives and other country-specific rules and regulations. For example, many countries, directly or indirectly through reimbursement limitations, control the cost of most clinical diagnostic products. Furthermore, many developing countries limit the importation of raw materials and finished products. International regulations may also have an impact on U.S. regulations. In addition, the FDA regulates the export of products from the United States.

Biodefense and Industrial Testing Products

Our biodefense products will be subject to stringent Federal, state, local and foreign laws, regulations and policies governing their manufacture, storage, sale, distribution and export. In addition, the U.S. government has adopted, and is expected to continue to adopt, laws, regulations and rules governing the research, development, procurement and handling of pathogens that may be used in a bioterrorist attack or other agents that may cause a public health emergency and to permit government inspection and oversight of facilities engaged in the research, development, manufacture or sale of select agents. Under several statutes recently enacted, the Department of Homeland Security, FDA, Department of Commerce and various other regulatory authorities have been charged with establishing and implementing programs designed to enhance the security of food and water supplies, as well as the environment, from terrorist attacks. These legislative initiatives include recordkeeping, registration, notification, import, export, manufacturing and various other compliance measures. This is a rapidly evolving regulatory landscape and many of the possible rules and regulations have not yet been proposed or adopted. We may be required to incur significant costs to comply with such laws and regulations in the future, and such laws or regulations may have a material adverse effect upon our ability to do business.

Life Science Research Products

Our products that will be sold for life science research use only, including the M-SERIES instruments used in the life science market, must be properly labeled as “for research use only — not for use in diagnostic procedures”, as required by the FDA, but do not generally require FDA approval prior to marketing. Research does not include clinical investigations and is narrowly defined by the FDA to apply to the early development of product concepts. The FDA has begun to impose new distribution requirements and procedures on companies selling research use only products, such as the requirement that the seller receive specified certifications from its customers as to the customers’ intended use of the product. We expect that the FDA will develop additional restrictions of this nature some of which may adversely affect us.

Clinical Diagnostic Products

The FDA, and other Federal, state, local, and foreign authorities, regulate, among other things, the development, clinical testing, manufacture, packaging, labeling, storage, distribution and promotion of medical devices, including products intended for clinical diagnostic purposes. The FDA imposes specific requirements on the conduct of clinical studies and requires approval of the study by an institutional review board and, in some cases, by the FDA, depending upon the product and its use. Before a new device can be introduced into the market, the manufacturer must generally obtain marketing clearance through a section 510(k) pre-market notification or approval through a pre-market approval application. The testing, preparation of necessary applications and processing of those applications by the FDA is expensive and time-consuming.

Our clinical diagnostic products and the clinical diagnostic products of our licensees will be regulated as medical devices. Significant difficulties or costs may be encountered to obtain FDA clearances or approvals and that could delay or preclude us or our licensees from marketing products for clinical diagnostic purposes. Furthermore the FDA may request additional data following the original submission. Delays imposed by the governmental review process may materially reduce the period during which our or our licensees will have the exclusive right to exploit our products or technologies.

The FDA will clear a device under section 510(k) if the submitted information establishes that the proposed device is “substantially equivalent” to a legally marketed class I or II medical device, or to a class III medical device for which the FDA has not yet called for a pre-market approval application. Commercial distribution can begin only after the FDA issues an order that the device is substantially equivalent to a device that is legally marketed and not subject to a pre-market approval requirement. The FDA may determine that a proposed device is not substantially equivalent to a legally marketed device, in which case a pre-market approval will be required to market the device, unless additional information can be submitted to support a substantial equivalence determination, or the FDA, pursuant to a timely request, makes a risk-based determination that a device that is not a substantially equivalent device can be classified into class I or II.

An FDA request for additional data could require that clinical studies of the device’s safety and effectiveness be performed. Clearance, if obtained, may be conditioned on labeling restrictions or conducting a lengthy postmarket surveillance study.

A pre-market approval application must be filed and approved before a device can be marketed if a proposed device is not substantially equivalent to a legally marketed device, as discussed above, or if it is a class III device that was in commercial distribution prior to May 28, 1976, for which the FDA has called for pre-market approval. A pre-market approval application must be supported by valid scientific evidence, which typically includes extensive pre-clinical data and well controlled or partially controlled clinical trials, to demonstrate the safety and effectiveness of the device. Obtaining approval can take several years and approval may be conditioned on, among other things, substantial restrictions on indications for use and the conduct of postmarket surveillance studies. Generally, the pre-market approval process requires much more extensive pre-filing testing than does the section 510(k) pre-market notification procedure and involves a significantly longer FDA review after the date of filing. In responding to a pre-market approval application, the FDA may grant marketing approval, may request additional information, may set restrictive limits on claims for use or may deny the application altogether.

After the pre-market clearance or approval for the medical device has been received, it may still be withdrawn if compliance with regulatory standards is not maintained or if problems occur after the device reaches the market. The FDA may require post-market surveillance programs to monitor the effect of medical devices that have been sold, and has the power to prevent or limit further marketing of medical devices based on the results of these post-marketing programs. In addition, the FDA’s medical device reporting regulation requires reports to the FDA whenever information reasonably suggests that a marketed device may have caused or contributed to

15

death or serious injury, or when a device malfunctions and if the malfunction were to recur, the device would be likely to cause or contribute to a death or a serious injury.

In addition to obtaining FDA approval for each medical device, under the pre-market approval application procedures, we or our licensees must seek FDA approval of their manufacturing facilities and procedures. The FDA will also inspect clinical diagnostics companies on a routine basis for regulatory compliance with its Good Manufacturing Practices regardless of whether the product was cleared under section 510(k) or approved under pre-market approval.

We and our licensees’ clinical diagnostic products will be affected by the Clinical Laboratory Improvement Amendments of 1988, which is intended to insure the quality and reliability of medical testing and may have the effect of discouraging, or increasing the cost of, clinical diagnostic testing. The regulations establish numerous requirements applicable to clinical diagnostics. Under these regulations, the specific requirements that a laboratory must meet depend upon the complexity of the tests performed by the laboratory. Under the clinical laboratory improvement regulations, all laboratories performing moderately complex or highly complex tests will be required to comply with stringent standards and requirements. Because the regulations’ interpretation is uncertain, it is possible that certain of we or our licensees’ products may be categorized as highly complex tests, in which case penetration of the point-of-care market would be reduced because not all laboratories would meet the standards required to conduct such tests.

In addition, future changes in regulations or interpretations made by the U.S. Department of Health and Human Services, FDA, Centers for Medicare & Medicaid Services or other regulatory bodies may adversely affect us and our licensees.

In addition to the foregoing, we will be, and our licensees are, subject to numerous Federal, state and local laws and regulations relating to such matters as safe working conditions, laboratory and manufacturing practices, fire hazard control, and environmental protection, including disposal of hazardous or potentially hazardous substances.

We do not expect compliance with these laws and regulations to have a material effect on our financial results, capital requirements or competitive position, and we have no plans for material capital expenditures relating to such matters. However, we and our licensees may be required to incur significant costs to comply with such laws and regulations in the future, and such laws or regulations may have a material adverse effect upon us and our licensees’ ability to do business.

Sales of our and our licensees’ products outside the U.S. are also subject to extensive regulatory requirements, which vary widely from country to country. The time required to obtain the necessary approvals may be longer or shorter than that required for FDA clearance or approval.

Government Contracts and Regulation

Our contracts with U.S. and foreign government agencies and departments require that we comply with numerous regulations, rules and policies, including those governing procedures for soliciting, awarding and funding government contracts. In addition, we are required to comply with numerous ongoing obligations following the award of a government contract, including those relating to record keeping, workplace compliance, third-party contracting, and disclosure of information. Failure to comply with these requirements may lead to a denial of a contract award, a challenge to a previously awarded contract, attempts by the U.S. government to terminate a contract, and restrictions on a company’s ability to participate in future bids to secure government contracts.

In addition, we are required to obtain certain security clearance certifications and comply with security clearance standards and requirements, including those affecting personnel and facilities. Sales of certain of our products to international government agencies may be subject to local government regulations and procurement

16

policies and practices, as well as to regulations relating to import-export control, including prior notification of, and pre-clearance for, export of certain goods having military applications.

During the years ended March 31, 2004, 2003, and 2002, agencies of the U.S. government accounted for 22%, 26% and 11% of total revenue, respectively, and 26% and 43% of total consolidated accounts receivable as of March 31, 2004 and 2003, respectively.

Environmental Regulation

Our operations are subject to stringent foreign, Federal, state and local laws, rules and regulations relating to the protection of the environment, including those governing the use, handling and disposal of hazardous, radioactive and infectious materials and wastes, the discharge of pollutants into the air and water and the cleanup of contaminated sites. Some of our operations will require permits, and these permits will be subject to modification, renewal and revocation by issuing authorities. Although we believe that we are in compliance with these laws and regulations in all material respects, we may be required to incur significant costs to maintain or achieve compliance if additional or stricter environmental and health and safety requirements are imposed in the future or in the event of any noncompliance at our facilities.

Reimbursement

Third-party payers, such as governmental programs and private insurance plans, can indirectly affect the pricing or the relative attractiveness of our products by regulating the maximum amount of reimbursement they will provide for diagnostic testing services. In recent years, healthcare costs have risen substantially, and third-party payers have come under increasing pressure to reduce such costs. In this regard, the Federal government, in an effort to reduce healthcare costs, may take actions that may involve reductions in reimbursement rates. If the reimbursement amounts for diagnostic testing services are decreased in the future, it may decrease the amount which physicians, clinical laboratories and hospitals are able to charge patients for such services and consequently the price we and our collaborators will be able to charge for products.

Seasonal Aspects, Backlog and Renegotiation

There are no significant seasonal aspects to our business. Orders for our products are generally filled on a current basis, and order backlog is not material to our business. A material portion of our business is subject to contracts that may be terminated at the election of the government.

In the event our biodefense business expands, the portion of our business subject to contracts that may be terminated at the election of the government is likely to expand. For a further description of risks related to our contracts with the government, see “Risk Factors — Risks Relating to Regulation and Government Contracts.”

Competition

We compete in the non-clinical diagnostics markets, including biodefense, industrial and life science markets with our diagnostic instruments, reagents and assays and expect to compete in the clinical diagnostics market. We believe that the principal competitive factors in these markets are:

17

Although we believe that we compete favorably with respect to the above factors, competition in the diagnostics market is intense and we do not hold a leading competitive position in any of the markets in which we compete.

We expect to compete with a number of domestic and international companies, including Roche, Johnson & Johnson, Abbott Laboratories, Bayer, Biosite Incorporated and Dade Behring, Inc. Many of our competitors now have and in the future may continue to have access to greater resources than we do and, therefore, may be better equipped to develop, manufacture, market and sell their products. These companies may develop and introduce products and processes competitive with or superior to ours. In addition, we will directly compete against our current and future licensees, including bioMérieux, Roche and MSD.

Manufacturing

Our current commercial manufacturing operations consist of the manufacture of the M-SERIES family of products and reagents, biodefense and industrial testing products, and cell culture research biologicals. We operate a qualified Good Manufacturing Practices and ISO 9001 facility. We use a variety of suppliers and believe that we do not depend on any supplier that cannot be replaced in the ordinary course of business. Any changes in source of supply may require additional engineering or technical development, with costs and delays that could be significant, to ensure consistent and acceptable performance of the products.

We do not manufacture any clinical diagnostic products. We are presently evaluating plans for future manufacturing of our clinical diagnostic products. These plans may include direct and third-party manufacturing. Negotiations are ongoing with a world leader in mobile electronics and systems technology to manufacture one of our instruments. There can be no assurance that these negotiations will result in an agreement with such manufacturer on terms favorable to us, if at all or that such manufacturer will be successful in manufacturing our instruments.

See “Risk Factors — Risks Relating to Us and Our Business — We have limited manufacturing experience, which puts us at a competitive disadvantage and could have a material adverse effect on our business, financial condition and revenue,” “Risk Factors — Risks Relating to Us and Our Business — We have limited manufacturing facilities for our products and we may not find additional facilities suitable for future growth, which could materially adversely affect our business and prospects” and “Risk Factors — Risks Relating to Us and Our Business — We depend on a limited number of suppliers for materials used in the manufacturing of our products, and any interruption in the supply of those materials could hamper our ability to manufacture products and meet customer orders.”

Sales and Marketing

We maintain a direct sales and marketing group in the United States and Europe that consists of approximately 14 people. Our direct sales group focuses on sales of the M-SERIES family of products and the BIOVERIS™ Detection System, together with reagents and services, to various government agencies in the biodefense market, food and beverage producers and contract testing laboratories in the industrial market and other potential customers in the life science market.

18

In addition to our direct and indirect sales and marketing efforts, our licensees and collaborators also conduct sales and marketing of our products. See “Business-Collaborations and License Arrangements.”

We are evaluating plans for the marketing and sale of our products currently in development. We may seek to market and sell a portion of our products indirectly through distributors who sell products that complement our products.

Human Resources

As of May 31, 2004, we and our subsidiaries employed 223 individuals, of whom 155 were engaged in research, product development, manufacturing and operations support, and 68 in marketing, sales and applications support and general administration. Of our employees, 22 have Ph.D. degrees. None of our employees is covered by a collective bargaining agreement, and management considers relations with its employees to be satisfactory.

Operating Segment

We currently operate in one business segment. We are currently engaged in the development, manufacturing and marketing of diagnostic products for the detection and measurement of biological and chemical substances. Information related to this segment is incorporated herein by reference to ITEM 8-“Consolidated Financial Statements-Notes to Consolidated Financial Statements-Note 10”.

Geographic Segments

We do not believe we have material risks relating to our foreign business. Financial information about geographic segments is incorporated herein by reference to ITEM 8-“Consolidated Financial Statements-Notes to Consolidated Financial Statements-Note 10”.

Risk Factors

Risks Relating to Us and Our Business

OUR BUSINESS HAS A HISTORY OF LOSSES AND WE WILL HAVE FUTURE LOSSES AND NEGATIVE CASH FLOW.

We incurred net losses of $93.3 million, $50.9 million and $49.2 million for the years ended March 31, 2004, 2003 and 2002, respectively. We expect to continue to incur operating losses and negative cash flow as a result of our expenses for manufacturing, marketing and sales capabilities, research and product development, general and administrative costs and our share of losses in MSD.

While we seek to attain profitability, we cannot be sure that we will ever achieve product or other revenue sufficient for us to attain this objective. Our ability to become profitable in the future will depend on, among other things, our ability to:

19

IF WE ARE UNABLE TO ESTABLISH NEW COLLABORATIONS, OR ANY COLLABORATIONS WE ESTABLISH DO NOT RESULT IN THE SUCCESSFUL INTRODUCTION OR MARKETING OF NEW PRODUCTS BASED ON OUR TECHNOLOGY, OUR GROWTH MAY BE SLOWED AND OUR BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED.

One aspect of our strategy is to enter into collaborative relationships with established healthcare and other companies to assist us in developing our technologies or manufacturing or marketing our products for certain markets. We may not be able to enter into collaborations on terms that are favorable to us, if at all. In addition, we cannot assure you that third parties, including our licensees, suppliers or others will not object to possible new collaborations. See “Risk Factors — Risks Relating to Us and Our Business — We and MSD may have different views of the scope of the exclusive license previously granted to MSD and the scope of MSD’s rights under the former joint venture agreement with us, which could affect our ability to expand our business directly or through collaborations.”

As a result of this strategy, we may have no, or only limited, control over the amount of resources that our collaborators will devote to the development or marketing of products based on our technology. For instance, our collaborators:

If any of these events occur with respect to one of the companies we are collaborating with, we would not receive the benefits of the collaboration and our growth could be slowed and our business could be materially adversely affected.

TO ACHIEVE COMMERCIAL SUCCESS, WE MUST COMPLETE THE DEVELOPMENT OF OUR PRODUCTS AND THOSE PRODUCTS MUST GAIN MARKET ACCEPTANCE OR OUR BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED.

Many of our potential products, including certain M-SERIES products, are at an early stage of development and we have not introduced any clinical diagnostics products. Products under development require additional research and development efforts, including clinical testing and regulatory approval, prior to commercial use. Our potential products are subject to the risks of failure inherent in the development of products based on new technologies. These risks include the possibilities that:

20

Our business, business prospects and financial results would be hurt if our products are not accepted as alternatives to other existing or new products and do not gain market acceptance.

In addition, we have licensed for a license fee of $50 million plus royalties as specified in the PCR license agreements certain PCR technology from Roche, which PCR technology we plan to integrate into certain of our new instrument systems. Although we do not currently sell, or have under development, any product based on the PCR technology being licensed from Roche, any products that we may develop using PCR technology will be also subject to the risks of failure inherent in the development of products based on new technologies as described above.

We have performed a valuation of the PCR technology license and recorded a value of $19.5 million and reflected a $30.5 million adjustment to the consideration paid by Roche with respect to the merger and related transactions. If we are unable to successfully develop any products using PCR technology because such PCR technology has become obsolete or the future undiscounted cash flows attributable to products using PCR technology are insufficient to realize the remaining carrying value of the license, we would be required to write off the remaining net book value or record an impairment of the value of the PCR license. Furthermore, if as a result of the claims made by Applied Biosystems against Roche, we are unable to use the PCR technology being licensed from Roche, we would also be required to write off the remaining net-book value of the PCR license. Such a write-off or the recording of such an impairment could have a material adverse effect on our future results of operations.

OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY, AND THESE FLUCTUATIONS MAY CAUSE OUR STOCK PRICE TO BE VOLATILE.

Our quarterly operating results will depend upon:

21

These factors may cause our quarterly operating results to fluctuate significantly, which in turn, may cause our stock price to be volatile. In addition, because our revenues and operating results are expected to be volatile and difficult to predict, we believe that period-to-period comparisons of our results of operations will not be a good indication of our future performance.

THE ACCOMPANYING CONSOLIDATED FINANCIAL STATEMENTS MAY NOT NECESSARILY BE INDICATIVE OF OUR FINANCIAL POSITION, RESULTS OF OPERATIONS OR CASH FLOWS HAD WE OPERATED ON A STAND-ALONE BASIS.

Our assets and businesses have historically been owned, operated and fully integrated with IGEN. Our accompanying consolidated financial statements have been prepared and are presented as if we had been operating as a separate entity. In order to fairly present our operating results, these financial statements reflect the application of certain estimates and allocations.

Our consolidated statements of operations include all revenues and costs that are directly attributable to our businesses, as well as certain expenses of IGEN that have been allocated to us using various assumptions.

These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total headcount, as appropriate. While management believes that the allocation methodologies are reasonable and appropriate, different allocation methodologies would result in changes to our operating results.

Upon completion of the merger and related transactions between Roche and IGEN, we became an independent, publicly-traded company and operate on a stand-alone basis. The financial information in the accompanying consolidated financial statements may not reflect our financial position, results of operations and cash flows in the future or what they would have been had we been operating as a stand-alone entity in the past.

WE MAY CHANGE THE FOCUS OF OUR BUSINESS OR ENTER INTO NEW HEALTHCARE FIELDS, WHICH COULD RESULT IN THE INCURRENCE OF ADDITIONAL COSTS AND EXPOSURE TO ADDITIONAL OR DIFFERENT BUSINESS RISKS.

We have broad discretion in determining the future strategy and focus of our business and may enter new healthcare fields in which we have limited or no experience. A significant change in the focus of our business could result in a loss of our previous investment, the incurrence of additional costs, including research and

22

development costs, and exposure to additional or different business risks. Incurrence of additional costs and exposure to additional risks could materially adversely affect our business.

WE MAY NOT BE ABLE TO RAISE SUFFICIENT ADDITIONAL CAPITAL TO SUCCESSFULLY DEVELOP OUR BUSINESS.

We will need substantial amounts of money to fund our operations on an ongoing basis. We expect our available cash to be sufficient to fund our operations for at least one year, but cannot predict how long our available cash will be sufficient to fund our operations thereafter.

We may need to raise substantial amounts of money to fund a variety of future activities integral to the development of our business, including:

The failure to raise sufficient additional capital for us to develop our business would adversely affect our business prospects.

OUR ACCESS TO FUNDS COULD BE NEGATIVELY IMPACTED BY MANY FACTORS, INCLUDING VOLATILITY IN THE PRICE OF OUR COMMON STOCK, LOSSES FROM OPERATIONS AND CAPITAL MARKET CONDITIONS.

We may not have access to enough funds on favorable terms, if at all, to successfully operate and develop our business. We may try to raise necessary additional capital by issuing additional debt or equity securities. Holders of debt securities would have priority over our equity holders with respect to the proceeds from the sale of our assets in the event of liquidation of our business, and any debt financings that we obtain may contain restrictive terms that limit our operating flexibility. If we raise additional capital by selling additional common or preferred stock, the holdings of existing stockholders would be diluted.

If we are unable to raise additional capital, we may have to consider pursuing arrangements with other companies that may not be available on terms favorable to us. In addition, we may have to scale back, or even eliminate, some of our programs.

WE MAY EXPERIENCE DESIGN, DEVELOPMENT, IMPLEMENTATION AND OTHER DIFFICULTIES THAT COULD DELAY OR PREVENT OUR INTRODUCTION OF NEW OR ENHANCED PRODUCTS OR AFFECT THE PERFORMANCE OF EXISTING PRODUCTS, WHICH COULD ADVERSELY AFFECT

23

OUR BUSINESS. IN ADDITION, IF THE MARKETS FOR OUR PRODUCTS CHANGE OR EVOLVE IN AN UNEXPECTED MANNER, OUR BUSINESS COULD BE MATERIALLY ADVERSELY AFFECTED.

The development of new or enhanced products is a complex and uncertain process requiring the accurate anticipation of technological and market trends as well as precise technological execution. We may experience design, development, implementation and other difficulties that could delay or prevent our introduction of new or enhanced products, or products that we may develop, manufacture or market with third parties or affect the performance of existing products, such as those which IGEN experienced with the development of M-SERIES instruments. These difficulties and delays may cause expenses to increase and our product sales to fluctuate. In addition, if we experience design, development or implementation difficulties in developing, manufacturing, distributing or marketing these instruments, we would sell fewer of our products and our business prospects would be adversely affected.

We expect the markets for our products to change and evolve. These changes could facilitate the market demand for our new or enhanced products, including the need for products that could be utilized in clinical point-of-care sites and field-testing of environmental samples in the biodefense market. If market demand does not change or evolve as we anticipate or if we are not able to develop products that meet the evolving market demand, our business prospects would be adversely affected.

In addition, the markets for our products are characterized by evolving industry standards and government regulations, the need for updated and effective technology and new product introductions. Our success will depend in part upon our ability to profitably enhance existing products and develop and introduce new products. We may not be able to avoid the obsolescence of our products due to technological change and evolving industry standards and government regulations.

If we experience design, development, implementation or other difficulties that delay or prevent our introduction of new or enhanced products or if the markets change or evolve in an unexpected manner, our business could be materially adversely affected.

WE EXPECT TO RELY ON SALES OF THE M-SERIES PRODUCT FAMILY FOR A SIGNIFICANT PORTION OF OUR REVENUES, AND A DECLINE IN SALES OF THESE PRODUCTS COULD CAUSE ADVERSE FINANCIAL RESULTS AND NEGATIVELY AFFECT OUR BUSINESS PROSPECTS.

We expect to derive a significant portion of our revenues from sales of M-SERIES products. Any factor adversely affecting the pricing or demand of M-SERIES products, including market acceptance of competing products, could cause our revenues to decline, resulting in adverse financial results and negatively affecting our business prospects.

Additionally, we intend to market M-SERIES products in markets in which we have little or no experience. We may not be able to successfully market the M-SERIES family of products in those markets, which could cause an adverse affect on our business prospects.

OUR COMPETITORS AND POTENTIAL COMPETITORS MAY HAVE OR DEVELOP DIAGNOSTIC PRODUCTS AND TECHNOLOGIES THAT ARE MORE ATTRACTIVE THAN OUR EXISTING OR FUTURE DIAGNOSTIC PRODUCTS.

Our business will be subject to intensive competition from established companies, development stage companies and research and academic institutions, and we expect this competition to intensify. Many of these companies and institutions have one or more competitive advantages over us, including, among other things:

24

As a result, our competitors may develop, manufacture market or sell diagnostic products that are more effective or commercially attractive than our current or future diagnostic products. In addition, these competitors may offer broader product lines, discounts and may have greater name recognition than us. Furthermore, we compete against companies that utilize ECL technology licensed to them by us, including Roche and MSD, a company in which we also have an interest.

As a result, we may not be able to compete successfully against our competitors. This could have a material adverse effect on our business, financial condition and revenues.

WE HAVE LIMITED MANUFACTURING EXPERIENCE, WHICH PUTS US AT A COMPETITIVE DISADVANTAGE AND COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS, FINANCIAL CONDITION AND REVENUE.

We lack experience in large-scale manufacturing and have no experience in the manufacturing of clinical diagnostic products, which could hamper our ability to manufacture existing products or new products that we develop. We have two options to address this competitive disadvantage.

First, we could expand our internal ability to manufacture products, which, to date, has only been done in a limited way. Second, we could contract with a third party to manufacture products for us based on our technology, which, to date, we have not done.

If we are unable to expand our own manufacturing capability or find a suitable manufacturer on acceptable terms in a timely manner, we may be unable to meet demand for existing products and could be delayed in introducing new products to the market. Failure to meet demand for existing products or delays in introducing new products could put us at a competitive disadvantage and could have a material adverse effect on our business, financial condition and revenue.

WE HAVE LIMITED MANUFACTURING FACILITIES FOR OUR PRODUCTS AND WE MAY NOT FIND ADDITIONAL FACILITIES SUITABLE FOR FUTURE GROWTH, WHICH COULD MATERIALLY ADVERSELY AFFECT OUR BUSINESS AND PROSPECTS.

We face risks inherent in operating a single facility for the manufacture of our products. We do not have alternative production facilities available should our Gaithersburg, Maryland manufacturing facility cease to function. If our facility were not operational for an extended period of time, including due to an unforeseen plant shutdown, then our business and future prospects could be materially adversely affected.

In addition, we may need to expand and enhance our research, development and production facilities. We may encounter difficulties in locating suitable additional facilities to meet our requirements. We may also be required to make material capital expenditures at a new facility at a time when we have limited capital resources available to us.

We may also experience difficulties or delays in integrating our operations into new facilities. These difficulties might include delays in the availability of a new facility or problems associated with equipment installation. In addition, any facility that we obtain for production of clinical testing or biodefense products will be subject, on an ongoing basis, to a variety of regulatory requirements including quality systems regulations, international

25

quality standards and other regulatory standards. We may encounter difficulties expanding our manufacturing operations in accordance with these regulations and standards, which could result in manufacturing delays and an inability to meet product demand and our business prospects could be materially adversely affected.

If we are not successful at identifying and obtaining additional facilities to meet our future growth needs, or we are unable to pay for facility enhancements and improvements, our business would suffer.

WE HAVE NO EXPERIENCE SELLING, MARKETING OR DISTRIBUTING CLINICAL DIAGNOSTIC PRODUCTS. OUR FAILURE TO ESTABLISH A SALES FORCE WITH TECHNICAL EXPERTISE OR TO ESTABLISH AN EFFECTIVE DISTRIBUTION SYSTEM FOR OUR CLINICAL DIAGNOSTIC PRODUCTS COULD MATERIALLY ADVERSELY AFFECT OUR BUSINESS PROSPECTS AND REVENUES.

We need to develop selling, marketing and distribution capabilities for our planned clinical diagnostic products. To market clinical diagnostic products directly to customers, and not through a licensee or third party distributor or collaborator, we will need to develop a substantial sales force with technical expertise. We will also need to establish a distribution system to support our sales force. Alternatively, we could license or contract with another company to provide sales and distribution services for our products. We may not be able to develop a sufficient sales and distribution force or find a suitable company to fill that role for us, which could materially adversely affect our business prospects and revenues.

FAILURE TO MANAGE OUR GROWTH COULD ADVERSELY AFFECT OUR BUSINESS.

We expect to grow by increasing our presence in existing markets and introducing new products we develop into new potential markets. Our growth strategy will place a strain on our management and our operating and financial systems.

As we grow, our personnel, systems, manufacturing capabilities and resources, procedures and controls may be inadequate to support future operations and we will need to hire, train and retain additional personnel. We may also need to improve and expand our financial and management controls, reporting systems and operating systems as well as other aspects of our infrastructure, including research and development or manufacturing facilities. We may encounter difficulties integrating additional personnel, as well as improving, expanding and integrating new systems or facilities, which could adversely affect our business.

THE SUCCESS OF OUR BUSINESS DEPENDS ON PATENTS THAT WILL EXPIRE OVER TIME AND THAT MUST BE ACTIVELY PURSUED, OBTAINED, MAINTAINED AND PROTECTED. OUR BUSINESS COULD BE HARMED IF WE HAVE FUTURE DISAGREEMENTS WITH ROCHE OVER THE SCOPE OF THE LICENSE AGREEMENT.

Our business success or failure will depend, in part, on our ability to pursue, obtain, and maintain adequate patent protection for ECL technology and our other technologies. Our patents may not adequately protect our technology from being used by our competitors.

Our business depends heavily on patents that will expire over time and may be challenged or circumvented by competitors. Patents allow us, for a time, to prevent others from using our inventions to compete against us.

Companies may challenge or seek to invalidate patents or circumvent valid claims in patents, all of which could make it necessary for us to defend our patents in litigation. Litigation over patents poses the following risks to our business:

26

If we lose some patent protection, our competitive advantage could be eroded, third parties may be able to use our technology without paying us and our financial condition and business prospects would be adversely affected.

Roche, through its affiliate, has been licensed by us to exploit ECL technology, subject to the limitations of the license agreement. Although the terms of the license agreement were negotiated in an effort to minimize the areas of potential future disputes, there are no assurances that we and Roche will continue to agree on the scope, permitted use and other material terms of the license agreement. Future disputes with Roche over the scope of the license agreement, such as disputes over the field or the types of products that Roche is permitted to develop and sell, might lead to lengthy and costly legal proceedings, which could adversely affect our financial condition and future business prospects.

OUR BUSINESS COULD BE HARMED IF WE INFRINGE, OR ARE ALLEGED TO HAVE INFRINGED, THE INTELLECTUAL PROPERTY OF OTHERS.

If our products or services were to infringe the intellectual property (including patent rights) of others, we or our licensees could:

If we or our licensees infringe the intellectual property (including patent rights) of others, our business could be damaged if we were unable to make necessary alterations or obtain a necessary license on acceptable terms, if at all.

In addition, if our products or services were alleged to have infringed the intellectual property (including patent rights) of others, we would be forced to defend ourselves in litigation and might be enjoined from further sale of our products or required to pay monetary damages or amounts in settlement of the suit, which could adversely affect our prospects, drain our financial resources and discourage other companies from working with us.

BECAUSE WE INTEND TO DEVELOP PRODUCTS THAT ARE BASED ON PATENTS AND TECHNOLOGY THAT WE HAVE LICENSED FROM OTHERS, THE OWNERS OF THOSE PATENTS AND TECHNOLOGY MIGHT CLAIM THAT PRODUCTS DEVELOPED OR SOLD BY US VIOLATE THOSE LICENSES. ADDITIONALLY, A THIRD PARTY MIGHT OBJECT TO A LICENSE THAT WE HOLD OR TO THE SCOPE OF THE LICENSE GRANTED TO US.

Our success or failure will also depend, in part, on the patent rights and technology of others, including patents and technology being licensed to us from affiliates of Roche. We have been licensed by affiliates of Roche to exploit certain improvements from Roche Diagnostics and certain PCR technology, subject to certain limitations. Although the terms of the improvements license agreement and the PCR license agreements were negotiated in an effort to minimize the areas of potential future disputes, there are no assurances that we and Roche will continue to agree on the scope, permitted use and other material terms of the improvements license agreement or the PCR license agreements. Future disputes with Roche over the scope, permitted use and other material terms of the improvements license agreement or the PCR license agreements, such as disputes over the field or types of products that we are permitted to develop and sell, may lead to lengthy and costly legal

27

proceedings, or could interfere with or preclude us from proceeding with one or more development programs, whether conducted independently or through a collaborative arrangement.

In addition, third parties may object to the scope, permitted use and other material terms of one or more of the licenses granted to us by certain Roche affiliates. For example, Roche has advised us that Applied Biosystems has notified Roche that one or more of the PCR licenses granted by certain Roche affiliates to us under the improvements license agreement and the PCR license agreements may infringe exclusive rights to PCR technology held by, or other contract rights of, Applied Biosystems. Applied Biosystems has commenced litigation and arbitration against Roche regarding their respective rights relating to PCR technology. There are no assurances that we will not be named as a defendant in either of those actions or that Roche will prevail in the litigation and arbitration, or that the terms of any resolution or settlement of these proceedings will not be unfavorable to us.

If we were named as a defendant in either of those proceedings, we would be subject to the risks identified in the immediately preceding risk factor. Further, a final determination, settlement or other resolution in the arbitration or litigation may limit, preclude or interfere with our ability to exploit certain PCR technology licensed under the improvements license agreement or the PCR license agreements. Although we do not sell, or have under development, any product based on the PCR technology being licensed from Roche, if Applied Biosystems prevails in its claims against Roche, we may be required to obtain a license from Applied Biosystems for certain patents covering PCR technology to avoid future potential claims of infringement related to any development program that we might establish for future products based on PCR technology and may face many of the risks described in the immediately preceding risk factor. “Business — Our Technology — PCR Technology”.

Further, we license technology from other companies and academic institutions. Because access to this technology is necessary to operate our business, we must be certain that we comply with these license agreements.

Our business could be harmed if we breached any of these license agreements and lost the rights to use this patented technology or if we were unable to renew existing licenses on acceptable terms, if at all, or get additional licenses that we may need on acceptable terms, if at all. In addition, we may need to litigate the scope and validity of patents held by others and such litigation could be a substantial cost for us.

WE AND MSD MAY HAVE DIFFERENT VIEWS OF THE SCOPE OF THE EXCLUSIVE LICENSE TO OUR TECHNOLOGY PREVIOUSLY GRANTED TO MSD AND THE SCOPE OF MSD’S RIGHTS UNDER THE FORMER JOINT VENTURE AGREEMENT WITH US, WHICH COULD AFFECT OUR ABILITY TO EXPAND OUR BUSINESS DIRECTLY OR THROUGH COLLABORATIONS.

We intend to expand our business through internal development programs and through new or expanded collaborative arrangements. MSD may view the scope of its exclusive license and other rights under its license agreement and other agreements with us in a way that interferes with or precludes us from proceeding with one or more development programs. There are no assurances that MSD will not object to our future business plans, whether conducted independently or through a collaborative arrangement. Additionally, MSD may believe that we must obtain MSD’s consent prior to entering into proposed collaborative arrangements. The other party to a proposed collaboration with us may also require us to obtain MSD’s consent to avoid any future disputes or disagreements. For example, in connection with the merger and related transactions, Roche required IGEN to obtain MSD’s consent to the execution and delivery of the license agreement. If we are required to obtain MSD’s consent for any reason, there are no assurances that we will be able to obtain that consent at all or on terms that would not have an adverse effect on our business, financial condition or results of operations. In addition, if we choose not to obtain MSD’s consent, MSD may sue us to enforce rights it believes it has. Such a lawsuit could materially harm our business and future business prospects.

28

WE RELY ON TRADE SECRETS AND OTHER INFORMATION THAT CANNOT BE PROTECTED BY PATENTS, WHICH COULD HARM OUR BUSINESS IF THEY WERE DISCLOSED TO OR INDEPENDENTLY DEVELOPED BY OTHERS.

In addition to patents, we also rely in our business on trade secrets, know-how and other proprietary information. If this information were disclosed to or independently developed by competitors, our business would suffer.

We seek to protect this information, in part, by entering into confidentiality agreements with licensees, employees and consultants that prohibit these parties from disclosing our confidential information. These agreements may not provide adequate protection for our trade secrets, know-how and other proprietary information or ensure that the information we share with others during the course of our business will remain confidential. We may not have sufficient legal remedies under the agreements or otherwise to correct or compensate for unauthorized disclosures or sufficient resources to seek redress.

If we are not able to be adequately redressed for the unauthorized disclosure of our trade secrets, know-how or other proprietary information, our competitive position may be undermined and our business may suffer.

WE DEPEND ON A LIMITED NUMBER OF SUPPLIERS FOR MATERIALS USED IN THE MANUFACTURING OF OUR PRODUCTS, AND ANY INTERRUPTION IN THE SUPPLY OF THOSE MATERIALS COULD HAMPER OUR ABILITY TO MANUFACTURE PRODUCTS AND MEET CUSTOMER ORDERS.

We depend on vendors to supply key materials that we use in our products. Some of these materials are available only from limited sources. From time to time, suppliers may extend lead time, limit supplies or increase prices due to capacity constraints or other factors. In the event of a reduction in, interruption of, or degradation in, the quality of the supply of any of the materials required by us, or an increase in the cost of obtaining those materials, we would be forced to locate an alternative source of supply. If no alternative source were available or if an alternative source were not available on a timely basis, at a reasonable cost or otherwise on acceptable terms, our ability to manufacture one or more of its products would be delayed or halted.

Any changes in sources of supply may require additional engineering or technical development to ensure consistent and acceptable performance of our products. If any of these events occur, our product costs may increase, we might be unable to deliver products in a timely fashion, we could lose sales as well as customers, and our business would be significantly harmed as a result.

WE DEPEND ON HIGHLY TRAINED AND SKILLED EMPLOYEES AND MANAGEMENT, AND WE MAY NOT BE ABLE TO ATTRACT AND RETAIN SUFFICIENT PERSONNEL, WHICH COULD ADVERSELY AFFECT OUR BUSINESS.

We need to hire staff and retain our staff, both of which are difficult in a competitive marketplace. Because we are a technology company, we depend heavily on scientists and engineers to develop products and to build a successful business. Research and development efforts could suffer if we are not able to hire and retain enough qualified scientists and engineers, which would adversely affect our business. We compete with other technology companies and research and academic institutions for experienced scientists. Many of these companies and institutions have greater resources than we do and thus may be in a better position to attract desirable candidates.

In addition to scientists, we also need to hire managers who have regulatory, manufacturing and marketing capabilities. If we are not able to hire managers with these skills, or develop expertise in these areas, our business could suffer.

29

MSD AND MST HAVE AGREED TO PURCHASE OUR INTEREST IN MSD BUT THERE IS NO ASSURANCE THAT THE PURCHASE PRICE WILL EQUAL OR EXCEED THE BOOK VALUE OF OUR INTEREST IN MSD AND IF IT DOES NOT, WE MAY INCUR A LOSS. IN ADDITION, THERE IS NO ASSURANCE THAT WE WILL RECEIVE THE FULL PURCHASE PRICE.

The MSD joint venture agreement expired upon completion of the merger between Roche and IGEN. As a result, MSD and MST had the right to purchase our interest in MSD. Pursuant to the settlement, MST and MSD agreed to purchase, and we agreed to sell, our entire interest in MSD. MSD and MST’s purchase of our interest will be for a purchase price equal to fair market value (determined in accordance with an appraisal process), minus a 7.5% discount factor. The appraisal process will be completed by October 15, 2004, at the latest. Once the fair market value and purchase price are determined, the purchase will occur. MSD or MST will be required to pay us the outstanding purchase price plus simple (cumulated, not compounded) interest at the fixed annual rate of 0.5% over the prime rate in effect on the date that MSD or MST, as the case may be, purchases the interests. The purchase price is payable over time in installments equal to the sum of 5% of MSD net sales, as determined in accordance with the MSD agreements, and 20% of the net proceeds realized by MSD from the sale of its debt or equity securities in any third-party financing after the date of the sale of our interest in MSD. We received a prepayment credit of $2.0 million against our payment obligations to MSD in connection with the settlement, and therefore the initial installment payments will be applied against this credit and not paid to us in cash.

As of March 31, 2004, the book value of our interest in MSD as recorded on our unconsolidated balance sheet was approximately $46.2 million, and we subsequently made an additional capital contribution of $5 million ($3 million of which was in cash) in connection with the settlement. There is no assurance that the purchase price will equal the book value of our interest and if it does not, we would have to record a loss on the sale of our interest.

We expect that MSD will require substantial additional funding for its ongoing operations. We do not intend to provide additional funding and we cannot predict whether MSD will obtain such funding. If MSD is not able to obtain the funding, we could lose our ability to realize the value of most or all of our investment in MSD.

Because the purchase price is payable only out of a percentage of MSD’s net sales or future financings, our receipt of the purchase price is dependent on MSD’s future performance. In the event sufficient future net sales of MSD or third-party financings do not materialize, we will not receive the full purchase price for our interest in MSD.

OUR ABILITY TO DEVELOP PRODUCTS MAY BE NEGATIVELY AFFECTED BY SOCIAL ISSUES RELATING TO ANIMAL TESTING.

Our research and development activities have occasionally involved, and in the future might involve, limited testing in mice and rats. In addition, testing in the future may involve other animals. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by pressing for legislation and regulation of such activities and by other means, our ability to develop products may be negatively affected by a ban on animal testing or by action taken by groups or individuals opposed to these tests.

Risks Relating to Regulation and Government Contracts

OUR ABILITY TO OBTAIN AND RETAIN U.S. GOVERNMENT CONTRACTS IS SUBJECT TO UNCERTAINTIES, AND U.S. GOVERNMENT CONTRACTS MAY BE TERMINATED, WHICH COULD MATERIALLY ADVERSELY AFFECT OUR FINANCIAL CONDITION, OPERATING RESULTS, BUSINESS AND PROSPECTS.

Our ability to secure or retain U.S. government contracts is subject to uncertainties related to the government’s future funding commitments. The prospects for our biodefense business are also highly sensitive to changes in

30

national and international government policies and funding priorities. Changes in domestic or foreign government policies or priorities, including funding levels through agency or program budget reductions by the U.S. Congress or executive agencies, could materially adversely affect our ability to retain or obtain U.S. government contracts, and our business prospects could suffer.

The U.S. government can terminate, suspend or modify any of its contracts with us either for its convenience or if we default by failing to perform under the terms of the applicable contract. A termination or suspension for convenience could result in our having excess capacity, inventory, personnel, unreimbursable expenses or charges or other adverse effects on our financial condition. A termination arising out of our default could expose us to claims for damages and may have a material adverse effect on our ability to compete for future U.S. government contracts and orders.

U.S. government contracts may span one or more years and may include multiple renewal options in favor of the U.S. government. U.S. government agencies generally have the right not to exercise these option periods for any reason, including lack of funding, or if the agency is not satisfied with the counterparty’s performance of the contract. If the U.S. government terminates any of our contracts, our financial condition and operating results could be materially adversely affected.

In addition to unfavorable termination provisions, certain of our U.S. government contracts contain provisions that grant to the U.S. government a non-exclusive, non-transferable, irrevocable, paid-up license to use inventions made by us in the course of performing such contracts, or have such inventions used by or on behalf of the U.S. government, for research or other government purposes. New U.S. government contracts we enter into may also include similar provisions.

WE MUST OBTAIN FOOD AND DRUG ADMINISTRATION CLEARANCE OR APPROVAL TO MARKET OUR CLINICAL DIAGNOSTIC PRODUCTS, WHICH IS OFTEN COSTLY AND TIME CONSUMING. IF WE DO NOT OBTAIN THE NECESSARY CLEARANCES OR APPROVALS, OUR BUSINESS PROSPECTS WOULD SUFFER.

The manufacture, packaging, labeling, advertising, promotion, distribution and sale of medical devices such as clinical diagnostic products are subject to governmental regulation by national and local government agencies in the United States and abroad. The U.S. Food and Drug Administration, or FDA, regulates many of the areas in which we conduct our research and in which we are and expect to be developing, manufacturing and marketing products. In particular, we must obtain FDA clearance or approval before we can market clinical diagnostic products, such as those in development for the clinical point-of-care market segment.

The process of obtaining necessary clearances or approvals is often costly, time consuming and uncertain. In addition, we may begin to distribute reagents specifically for research use under an exemption. If the FDA disagrees with our classification of, or the manner in which we market and sell those reagents, it may impose restrictions on our business operations and subject us to sanctions that could adversely affect our business prospects. We have very limited experience obtaining FDA clearance and approval and may not be successful in obtaining FDA clearance or approval for any of our clinical diagnostic products, which would materially adversely affect our business prospects. Further, clearance or approval may place substantial restrictions on the indications for which the product may be marketed or to whom it may be marketed.

To obtain permission from the FDA to market in the U.S., we, or the companies we work with, will need to either obtain Section 510(k) pre-market notification clearance or approval of a pre-market approval application from the FDA. To obtain clearance for marketing, we, or the companies we work with, must demonstrate substantial equivalence to a similar legally marketed product by submitting a pre-market notification to the FDA. The FDA may require preclinical and clinical data to support a substantial equivalence determination. Clinical trials for gathering supporting data can take extended periods of time to complete and there can be no assurance that the FDA will find a device substantially equivalent.

31

If we do not successfully demonstrate substantial equivalence, or if we are required to obtain pre-market approval, we would have to conduct extensive clinical testing of these products, which could take years to complete. Extensive testing could involve substantial additional costs and might delay bringing clinical diagnostic products to market, weakening our competitive position. If we fail to obtain FDA clearance or approval for new products altogether, we will be unable to market these products at all for clinical use in the U.S.

WE ARE SUBJECT TO COMPREHENSIVE GOVERNMENT REGULATION, WHICH MAY INVOLVE SIGNIFICANT COSTS AND MAY RESTRICT OUR ABILITY TO CONDUCT BUSINESS.

We expect that certain of our future products will be subject to continuing FDA requirements, including compliance with the FDA’s Good Manufacturing Practices and the FDA’s medical device reporting regulation. We expect that we may need to spend a substantial amount of money to comply on an ongoing basis with government regulations. Government agencies, such as the FDA, Department of Homeland Security, Department of Commerce and the Environmental Protection Agency, or EPA, regulate many of our products as well as products that we plan to develop, manufacture, market and sell, including products for the clinical diagnostics, biodefense and industrial markets.

The costs of complying with governmental regulations and any restrictions that government agencies might impose could have a significant impact on our business. If we increase our manufacturing and expand our product offerings, these costs will increase.

Whether we directly manufacture products or contract with another company to manufacture products based on our technology, the FDA and other government agencies will continually review and periodically inspect the manufacturing process. If any of these agencies were to discover a problem with our products, the manufacturing process or the manufacturing facility, they could place restrictions on these products and on the manufacturer and impose sanctions. For example, the FDA could require us to recall, or even totally withdraw, a product from the market or close a manufacturing facility.

In addition to FDA regulations, the process of manufacturing products is subject to a variety of environmental laws and regulations, including laws and regulations governing the use, management and disposal of hazardous, radioactive and infectious materials and wastes, the discharge of pollutants into the air and water, and the cleanup of contaminated sites. We could incur substantial costs, including cleanup costs, fines and penalties, claims for damages, such as personal injury or property damages, and loss of permits required for our operations, if we fail to comply with these laws or regulations. Our operations are also subject to various employee health and safety laws and regulations, including those concerning occupational injury and illness and employee exposure to hazardous, radioactive and infectious materials.

While we have procedures in place to protect employees from exposure to such materials, we cannot assure you that potentially harmful exposure will not occur or that we will not be liable to employees as a result. In addition, because of the limited information currently available regarding some of the hazardous, radioactive and infectious materials used in our businesses, there may be unknown risks involved with the use of and exposure to such materials. In some circumstances there may be no body of knowledge or standard protocols for dealing with these risks. Costs associated with such environmental, health and safety matters could have a material adverse effect on our business and financial condition. In addition, in connection with our biodefense business, the DOD or other government agencies may require additional security measures to be implemented at our facility, which could cause us to incur substantial additional costs.

OUR BUSINESS COULD BE ADVERSELY AFFECTED BY A NEGATIVE AUDIT BY THE U.S. GOVERNMENT.

U.S. government agencies routinely audit and investigate government contractors. These agencies review a contractor’s performance under its contracts. If an audit results in a finding of improper activities, we may be subject to civil and criminal penalties and administrative sanctions, including termination of contracts,

32

forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government. In addition, we could suffer serious harm to our business reputation if allegations of impropriety were made against us.

COST OVER-RUNS ON CONTRACTS WITH THE U.S. GOVERNMENT COULD SUBJECT US TO LOSSES OR ADVERSELY AFFECT OUR FUTURE BUSINESS.

Our U.S. government contracts are fixed-price contracts and therefore we receive a fixed price irrespective of the actual costs we incur in connection with the performance of the contracts. Consequently, we will be required to absorb any costs in excess of the fixed price that may be set forth in the contract. If we are unable to control the costs we incur in performing under these contracts, our financial condition and operating results could be materially adversely affected. Cost over-runs also may adversely affect our ability to sustain our performance under the contract and obtain future U.S. government contract awards.

RESTRICTIONS ON HEALTHCARE COSTS AND HEALTHCARE AND INSURANCE FINANCING PRACTICES COULD LIMIT DEMAND FOR OUR PRODUCTS, WHICH WOULD HURT OUR BUSINESS AND BUSINESS PROSPECTS.

In the U.S. and elsewhere, demand for clinical diagnostic testing is dependent, in part, on consumers’ ability to be reimbursed for the cost of the tests by third-party payers, such as government agencies, health maintenance organizations and private insurers. Medicaid and other third-party payers are increasingly challenging the prices charged for medical services, including clinical diagnostic tests. They are also attempting to contain costs by limiting their coverage of, and the amount they will reimburse for, clinical diagnostic tests and other healthcare products.

Without adequate coverage and reimbursement, consumer demand for clinical diagnostic tests may decrease. Decreased demand would likely cause potential sales of our clinical diagnostic products, and sales by our licensees, to decrease because fewer tests would be performed or prices would be lowered, or both. Reduced sales or royalty income would hurt our business and business prospects.

In many foreign markets, governments directly set the prices that clinical diagnostic companies may charge for their products and services. In the U.S., a number of legislative and regulatory proposals aimed at changing the healthcare system have been proposed in recent years and we expect this to continue. Foreign and domestic legislative and regulatory initiatives that limit healthcare coverage may have a material adverse effect on our business and business prospects.

Risks Relating to the Industry

WE ARE EXPOSED TO PRODUCT LIABILITY RISKS THAT, IF NOT ADEQUATELY COVERED BY INSURANCE, MAY HAVE A MATERIAL ADVERSE EFFECT ON OUR FINANCIAL CONDITION.

Product liability is a major risk in marketing products for the clinical diagnostics, biodefense and industrial markets. We may not be able to insure adequately against risk of product liability. We may face product liability for claims and lawsuits brought by customers. Damages awarded in product liability cases can be very large. While we have product liability insurance, this coverage is limited.

We may not have adequate product liability insurance to cover us against our potential liabilities or be able to maintain current levels of product liability insurance on acceptable terms, if at all. Claims or losses in excess of our product liability insurance coverage or not covered by our product liability insurance could have a material adverse effect on our financial condition.

Risks Relating to Our Common Stock

33

OUR EXECUTIVE OFFICERS AND DIRECTORS EXERCISE SIGNIFICANT INFLUENCE OVER US AND MAY HAVE SIGNIFICANT INFLUENCE OVER THE OUTCOME OF PROPOSED CORPORATE ACTIONS SUPPORTED OR OPPOSED BY OTHER STOCKHOLDERS.

Our executive officers and directors, in the aggregate, own approximately 22.8% of the outstanding shares of our common stock. Our chairman and chief executive officer owns approximately 17.8% of the outstanding shares of our common stock. As a result, certain of our executive officers or directors may have significant influence over the election of directors and may be able to significantly influence the outcome of proposed corporate actions supported or opposed by other stockholders. In addition, as a result of their shareholdings, certain of our executive officers and directors could have significant influence over the outcome of potential transactions, including acquisition transactions, that may be supported by other stockholders.

PROVISIONS IN OUR CHARTER DOCUMENTS MAY DISCOURAGE POTENTIAL ACQUISITIONS OF US, EVEN THOSE WHICH THE HOLDERS OF A MAJORITY OF OUR COMMON STOCK MAY FAVOR, WHICH MAY ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK, REDUCE THE LIKELIHOOD OF OFFERS TO ACQUIRE US AND PREVENT CHANGES IN OUR MANAGEMENT.

Our certificate of incorporation and by-laws contain provisions that may have the effect of discouraging a third party from acquiring us by means of a tender offer, proxy contest or otherwise. Our certificate of incorporation and by-laws:

In addition, under our certificate of incorporation, our board of directors also has the authority to issue up to 15,000,000 shares of preferred stock in one or more series. Our board of directors can fix the powers, preferences and rights of any such series without stockholder approval.

Our board of directors could, therefore, issue, without stockholder approval, preferred stock with voting and other rights that could adversely affect the voting power of the holders of our common stock or otherwise make it more difficult for a third party to gain control of us.

Such provisions would make the removal of incumbent directors more difficult and time-consuming and may have the effect of discouraging a tender offer or other takeover attempt not previously approved by our board of directors.

34

In addition, we have adopted a stockholder rights agreement, pursuant to which one right attached to each share of our common stock outstanding. These rights will in most cases cause substantial dilution to a person that attempts to acquire or merge with us without the approval of the our board of directors by permitting the holders of these rights (other than the person attempting to acquire or merge with us) to, upon the occurrence of specified circumstances, purchase, at a substantial discount, shares of our series A participating cumulative preferred stock or shares of common stock of the person that attempts to acquire or merge with us. Accordingly, the existence of these rights may deter potential acquirers from making a takeover proposal or a tender offer.

WE DO NOT PLAN TO PAY ANY CASH DIVIDENDS ON OUR COMMON STOCK.

We have no plans to pay cash dividends on our common stock in the foreseeable future, if at all.

WE MAY NEED TO RAISE ADDITIONAL CAPITAL IN THE FUTURE AND WE MAY GRANT OPTIONS OR OTHER EQUITY-BASED AWARDS TO OUR EXECUTIVE OFFICERS, DIRECTORS, EMPLOYEES AND CONSULTANTS, FROM TIME TO TIME, EITHER OF WHICH WOULD RESULT IN DILUTION TO OUR STOCKHOLDERS.

Your investment in our common stock could be diluted if we issue additional shares of our common stock or securities convertible into, or exercisable for, shares of our common stock in the future, which we may need to do to raise funds for our business. Sales of additional shares of our common stock or the conversion of securities into, or the exercise of securities for, shares of our common stock could cause the market price of our common stock to decrease.

Under the BioVeris 2003 stock incentive plan, our executive officers, directors, employees and consultants may from time to time be granted options or other equity-based awards, such as phantom stock or restricted stock, to purchase up to 5.3 million shares of our common stock. If our executive officers, directors, employees and consultants exercise their options or other equity based awards, if and when granted and exercisable, and purchase shares of our common stock, your investment in our common stock will be diluted.

THE EXON-FLORIO ACT MAY INHIBIT POTENTIAL ACQUISITION BIDS, WHICH MAY ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK.

Section 721 of Title VII of the Defense Production Act of 1950, also known as the Exon-Florio Act, authorizes the president of the U.S. or his designees to initiate an investigation into the potential effects on national security of a business combination of a U.S. corporation and a foreign entity that could result in foreign control of the U.S. corporation. Subject to certain exceptions, under the Exon-Florio Act, the president may suspend or prohibit any foreign acquisition, merger or takeover of a U.S. corporation if there is credible evidence that the foreign entity exercising control might take action that threatens national security and there is no provision of law adequate to protect national security.

Due to our current and potential future involvement in the biodefense industry, the Exon-Florio Act could inhibit potential acquisition bids from foreign entities, which could adversely affect the market price of our common stock.

ITEM 2.      PROPERTIES

Our principal administrative, marketing, manufacturing and research and development facilities consist of approximately 165,000 square feet located in five buildings in Gaithersburg, Maryland. We have an additional 21,000 square feet of leased research and development, sales and office facilities in McLean, Virginia; San Diego, California; New York, New York; the District of Columbia; and Oxfordshire, England.

Our leases expire at various times from 2005 through 2010. We believe that current facilities should be adequate for immediate business requirements but additional facilities may be required if we successfully expand our business operations. We are evaluating new facilities for development, manufacturing and other corporate uses and if we secure new space, it would result in additional facilities costs.

See ITEM 1 — “Business — Risk Factors — Risks Relating to Us and Our Business” and ITEM 7 — “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

ITEM 3.      LEGAL PROCEEDINGS

35

In June 2004, the Audit Committee of our Board of Directors commenced an investigation of MSD that was prompted by the discovery of a series of transactions undertaken by MSD involving the actual or proposed purchase by MSD of residential real property and luxury automobiles having an aggregate cost of approximately $7 million. The transactions were entered into by MSD upon Jacob Wohlstadter’s sole approval and without our knowledge.

On June 15, 2004, we filed an action in the Court of Chancery of the State of Delaware, which we refer to in this Form 10-K as the Court, against Jacob Wohlstadter, MSD and MST, seeking Court confirmation that we remained entitled to designate one of the two members of the MSD Board of Managers, and asking the Court to enter an order, pending the outcome of the litigation, prohibiting MSD from taking any actions outside the ordinary course of MSD’s business without providing prior notice to us. On June 17, 2004, the Court ordered that, pending the Court’s final determination of the lawsuit, our representative on the MSD Board of Managers was to remain on the MSD Board of Managers and that MSD was not to engage in any transaction outside the ordinary course of business which had a value in excess of $10,000 without the approval of both members of the MSD Board of Managers. Also on June 15, 2004, we submitted a formal demand to MSD requesting the right to examine certain books and records of MSD to aid the Audit Committee in its investigation and to permit us to value our interest in MSD. Beginning late June, MSD permitted us to examine the requested books and records.

On June 17, 2004, MSD received $2.9 million from Jacob Wohlstadter as consideration for the proposed sale by MSD to Jacob Wohlstadter of real property and automobiles, pending approval by the Board of Managers. Jacob Wohlstadter also assumed MSD’s purchase obligations with respect to a prospective real property purchase in the approximate amount of $4.1 million.

Also on June 17, 2004, we were informed by the staff of the Securities and Exchange Commission that it had commenced an informal inquiry as to certain issues relating to MSD.

On July 6, 2004, we entered into an agreement with MSD, MST and Jacob Wohlstadter pursuant to which it was agreed that the lawsuit filed on June 15, 2004 would be stayed, that the parties would not file new litigation against each other, and that the valuation process in connection with MST’s and MSD’s right to purchase our interest in MSD would be stayed. This stay agreement was intended to permit the parties to engage in substantive negotiations to resolve the disputed matters and in order to permit us to finalize our Form 10-K for the fiscal year ended March 31, 2004. This stay agreement terminated automatically on July 13, 2004 because MSD’s representation letters to the auditors of MSD were not executed.

Because we are required to consolidate the financial information of MSD pursuant to FASB Interpretation No. 46, which we adopted as of March 31, 2004, we require the audited financial statements of MSD to complete our Form 10-K. We were not able to file our Form 10-K on a timely basis because the MSD financial statements were not available and because we were unable to conclude on the appropriate accounting for MSD.

On July 14, 2004, we filed a second action with the Court against MSD, MST and Jacob Wohlstadter. The action alleged, among other things, breach of fiduciary duty and contract, and sought relief including the dissolution of MSD and the appointment of a liquidating trustee.

Also in July 2004, the Audit Committee retained an independent special counsel to investigate whether our management had any prior knowledge of the real property and automobile transactions of MSD described above. This special counsel reported to the Audit Committee that there was no evidence that any member of our management knew of the MSD transactions at issue before they occurred.

On July 16, 2004, we received a letter from the staff of the Nasdaq Listing Qualifications Department notifying us that our common stock was subject to delisting from The Nasdaq Stock Market, Inc. because we had not yet filed our Form 10-K for the period ending March 31, 2004. In accordance with applicable NASD Marketplace Rules, we requested a hearing to review the Nasdaq staff determination before a Nasdaq Listing Qualifications Panel, which is scheduled for August 19, 2004. As a result of such request, the delisting of our stock was automatically stayed.

36

On July 19, 2004, all members of the Board of Directors met to review the MSD litigation and related issues. This review included a consideration of the status of the litigation, as well as the effects of the disputes on us generally, including management’s ability to conduct our business and to pursue our strategy and the notification from Nasdaq concerning possible delisting of our common stock as a result of our failure to file our Form 10-K on a timely basis. All members of the Board of Directors participated in this review, although some discussions were conducted by the independent directors without the management directors, Samuel Wohlstadter and Richard Massey, or other members of management. As a result of this review, the Board of Directors, with all members participating, unanimously approved a resolution that delegated to the Joint Venture Oversight Committee, or JVOC, the power and authority to (i) initiate, review, evaluate and determine the course of action we should pursue with respect to the pending litigation and any additional litigation against MSD, (ii) communicate and negotiate the terms of any proposed settlement of such litigation and any other matters with respect to MSD and (iii) otherwise deal with MSD in a manner the JVOC deemed to be in the best interests of our company and our stockholders. The resolution also appointed Messrs. Quinn and Crowley as additional members of the JVOC, resulting in the JVOC consisting of all five independent directors, and provided that action of the JVOC should be by unanimous approval of its members. The resolution also directed the JVOC to consult with our management and members of the Board who are not on the JVOC regarding the MSD matters. In addition, by unanimous vote of the five independent directors without the participation of Messrs. Wohlstadter and Massey, the Board of Directors approved a resolution directing the JVOC to pursue negotiations to settle the litigation and other outstanding disputes with MSD, MST and Jacob Wohlstadter and setting forth general terms that would be acceptable for such a settlement.

Between July 19, 2004 and August 3, 2004, there were meetings, telephone conferences and other communications among representatives of the JVOC, MSD, MST and Jacob Wohlstadter to discuss the terms of a settlement. On July 21, 2004, we entered into an agreement with MSD, MST and Jacob Wohlstadter to stay the litigation during these negotiations. During this period, the JVOC also communicated from time to time with our management (other than Samuel Wohlstadter) concerning various aspects of the settlement. Members of management (other than Samuel Wohlstadter) also communicated directly with MSD, MST and Jacob Wohlstadter on particular aspects of the settlement.

On August 3, 2004, the JVOC unanimously approved a draft settlement agreement. Following this approval, a telephonic meeting of the full Board of Directors was held to review the status of the SEC investigation, the status of the Nasdaq notification regarding possible delisting, and the proposed settlement. During this meeting, the management directors, who were previously provided with a copy of the draft settlement agreement, were invited to ask questions or give comments concerning the draft settlement agreement. The management directors informed the independent directors that they had no questions or comments.

On August 12, 2004 the parties entered into the settlement agreement. Under the settlement, the parties agreed to the following:

The foregoing is a summary of the material terms of the settlement and is qualified in its entirety by reference to the settlement agreement which is included as an exhibit to this report and which is incorporated herein by reference.

We are involved, from time to time, in various routine legal proceedings arising out of the normal and ordinary operation of our business, which we do not anticipate will have a material adverse impact on our business, financial condition, results of operations or cash flows. However, we may in the future be involved in litigation relating to our business, products or intellectual property, which could adversely affect our prospects or impair our financial resources.

See Item 1-“Business-Risk Factors — Risks Relating to Us and Our Business — The success of our business depends on patents that will expire over time and that must be actively pursued, obtained, maintained and protected. Our business could be harmed if we have future disagreements with Roche over the scope of the license agreement,” Item 1-“Business-Risk Factors — Risks Relating to Us and Our Business — Our business could be harmed if we infringe, or are alleged to have infringed, the intellectual property of others” and Item 1-“Business- Risk Factors — Risks Relating to the Industry — We are exposed to product liability risks that, if not adequately covered by insurance, may have a material adverse effect on our financial condition.”

ITEM 4.      SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

We became a publicly-traded company on February 13, 2004, and no matter was submitted to a vote of our security holders during the fourth quarter of the fiscal year covered by this report. The merger and related transactions, as well as our 2003 stock incentive plan, were approved by IGEN’s stockholders at a special meeting of stockholders of IGEN held on February 13, 2004.

PART II

ITEM 5.      MARKET FOR COMPANY’S COMMON STOCK AND RELATED STOCKHOLDER MATTERS

Common Stock

Our common stock began trading on February 17, 2004 and is quoted on The Nasdaq National Market under the symbol “BIOV”. Prior to that time, there was no public market for our common stock. As of June 1, 2004, there were approximately 177 holders of record of our common stock.

The number of record holders is based on the actual number of holders in our books and does not include holders of our common stock in “street” name or individual participants in security position listings maintained by depositary trust companies.

The following table sets forth the range of high and low bid price per share of our common stock as quoted on The Nasdaq National Market during the fourth quarter of fiscal 2004.

39

No cash dividends have been paid on our common stock to date, and we currently intend to retain any earnings for development of our business.

2003 Stock Incentive Plan

In September 2003, our Board of Directors adopted the 2003 stock incentive plan pursuant to which 5.3 million shares of our common stock have been reserved for issuance upon the exercise of options granted under the plan. The 2003 stock incentive plan was approved by IGEN stockholders prior to the completion of the merger and related transactions on February 13, 2004. The following table sets forth certain information with respect to our 2003 stock incentive plan as of March 31, 2004.

For more information about our 2003 stock incentive plan, see ITEM 8 -“Consolidated Financial Statements — Notes to Consolidated Financial Statements-Note 2”.

Series B Preferred Stock

On February 17, 2004, we sold 1,000 shares of series B preferred stock to Samuel J. Wohlstadter for an aggregate consideration of $7.5 million. The shares of series B preferred stock were not, and will not be, registered under the Securities Act of 1933 and were sold solely to Samuel J. Wohlstadter pursuant to Section 4(2) of the Securities Act of 1933. There is no established public trading market for shares of series B preferred stock. As of June 30, 2004, Samuel J. Wohlstadter is the only holder of series B preferred stock and no dividends have been declared or paid with respect to shares of series B preferred stock. The series B preferred stock, and the proceeds from the sale were applied to fund a portion of the $37.5 million capital contribution that we made to MSD following the completion of the merger and related transactions. Under the terms of the series B preferred stock, we may redeem the series B preferred stock at $0.01 per share at any time that we are no longer entitled to receive distributions with respect to our class C interest in MSD pursuant to the MSD agreements. We will redeem a proportionate part of the series B preferred stock in connection with any redemption by MSD of our class C interests in MSD.

In connection with the settlement, we received a $2.0 million non-refundable pre-payment from MSD for future amounts payable by MSD to us pursuant to the buy-out of our interest in MSD. The holder of our Series B preferred stock will be entitled to a pro-rata share, representing the proportionate amount of our class C interest in MSD that was funded by the sale of the Series B preferred stock, of the portion of the $2 million that is allocable to our class C interests.

ITEM 7.      MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The numbers in this Management’s Discussion and Analysis of Financial Condition and Results of Operations may not tie directly to the numbers in our Consolidated Financial Statements due to rounding.

Overview

On February 13, 2004, IGEN and Roche completed the merger and related transactions pursuant to which Roche acquired IGEN and IGEN simultaneously distributed shares of our common stock to its stockholders. The transaction occurred in the following steps:

43

Prior to February 13, 2004, our assets and businesses were owned and operated by IGEN. Our financial statements have been prepared and are presented as if we had been operating as a separate entity in periods prior to February 13, 2004 using the historical cost basis in the assets and liabilities of IGEN and including the historical operations of businesses and assets transferred to us from IGEN as part of the merger and related transactions.

Results of operations in the future are likely to fluctuate substantially from quarter to quarter as a result of various factors, which include:

44

We expect to incur additional operating losses as a result of our expenses for manufacturing, marketing and sales capabilities, research and product development, general and administrative costs, and the net loss of MSD, whose financial results have been consolidated with ours beginning as of March 31, 2004. Our ability to become profitable in the future will be affected by, among other things, our ability to expand the distribution and increase sales of existing products, upgrade and enhance the M-SERIES family of products, introduce new products into the market, generate higher revenue, develop marketing, sales and distribution capabilities cost-effectively, and continue collaborations established by IGEN or establish successful new collaborations with corporate partners to develop, manufacture, market and sell products that incorporate our technologies.

Investment in MSD

MSD is a joint venture formed by MST and IGEN in 1995. MSD was formed for the development, manufacture, marketing and sale of products utilizing a proprietary combination of MST’s multi-array technology together with our ECL technology. We have recorded our proportionate share of MSD losses, representing approximately 100% of MSD’s losses.

In January 2003, the FASB issued Interpretation No. 46, “Consolidation of Variable Interest Entities,” or FIN 46. FIN 46 provides guidance on variable interest entities such as the MSD joint venture and the framework through which an enterprise assesses consolidation of a variable interest entity. We adopted FIN 46 as of March 31, 2004 and have determined that MSD qualifies as a variable interest entity. Accordingly, beginning as of March 31, 2004 we have consolidated the financial results of MSD. Under the transition guidance of FIN 46, because MSD was created before February 1, 2003, we have measured the assets, liabilities and noncontrolling interests of MSD as of March 31, 2004 for purposes of the initial consolidation. The amounts of the assets, liabilities and noncontrolling interests are reflective of their respective carrying amounts had FIN 46 been effective when we first met the conditions to be the primary beneficiary of MSD upon MSD’s inception in 1995. We have historically recorded approximately 100% of MSD’s losses. In connection with the merger and related transactions, we made a $37.5 million payment to MSD. We determined that at the time of the payment, recording the entire payment to the investment in joint venture account would result in the book value of the Company’s investment in MSD being greater than its fair market value. Accordingly, we expensed $33.7 million, which represented the amount of the payment that gave rise to its net recorded investment exceeding the fair market value of its interests. Upon implementation of FIN 46, we recorded a one-time, non-cash $33.7 million adjustment to reflect this change in accounting principle, thereby adjusting the book value of our investment in the MSD joint venture to equal the consolidated net assets of MSD. In fiscal 2005, the statement of operations will reclassify amounts formerly recorded on a “net” basis as equity in loss of joint venture to be reflected on a “gross” basis primarily as revenue, product costs, research and development expenses and selling, general and administrative expenses.

The MSD joint venture agreement expired upon completion of the merger and related transactions. As a result, MSD and MST had the option to purchase our interest in MSD. As of March 31, 2004, the value of such option to purchase our interest was $1.2 million, which has been recorded as a liability and as other expense on the accompanying consolidated statements of operations. Pursuant to the settlement, MSD or MST will purchase, and we will sell, our entire interest in MSD. We are in the process of evaluating the impact of this purchase on our future of accounting treatment for

45

MSD under the provisions of FIN 46. For a more complete description of this purchase right and the MSD agreement, see ITEM 13 —“Certain Relationships and Related Transactions”.

The purchase price is payable in installments from a percentage of MSD’s future net sales or financings. There is no assurance the purchase price will be paid in full. In particular, we expect that MSD will require substantial additional funding for its ongoing operations. If MSD is not able to obtain this funding, it may not be able to pay the purchase price in full and we could lose our ability to realize the value of most or all of our investment in MSD.

In June and July 2004, we commenced legal actions against MSD, MST and Jacob Wohlstadter in the Court of Chancery in the State of Delaware that were prompted by the discovery of a series of actual and proposed transactions undertaken by MSD without our knowledge. These lawsuits were settled in August 2004. See ITEM 3 — “Legal Proceedings” for a more complete description of the lawsuits and the related settlement.

Results of Operations

Years Ended March 31, 2004 and 2003

Revenues. Total revenues for the fiscal year ended March 31, 2004 increased by approximately $2.2 million, or 12%, to $20.0 million from $17.8 million in fiscal 2003.

Product sales were $18.7 million in fiscal 2004, an increase of 14% over the prior year’s product sales of $16.5 million. This growth in product sales was from biodefense products, an increase of $1.5 million to $6.1 million, and products for the life science market, an increase of $700,000 to $12.6 million. These increases in product sales during fiscal 2004 reflect the growth of orders and product deliveries for biodefense products and M-SERIES systems, which orders and deliveries are based on our customers’ requirements.

We anticipate increases in biodefense-related sales as a result of our ongoing biodefense initiatives. As part of the merger and related transactions, we assumed a contract between IGEN and the DOD pursuant to which the DOD may purchase tests for the detection of specific toxins in environmental samples from IGEN. Under the contract, the DOD may, at its option, make purchases of up to $23.0 million over a period of up to 48 months. As of March 31, 2004, the DOD had purchased approximately $3.4 million of products.

Sales of our products for the life science market are subject to a number of uncertainties, including the fact that we are not a party to significant long-term contracts for the sale of our products for the life science market that would provide predictable sales. Therefore, the volume and timing of product orders from our life science customers are based on their requirements, which may vary over time. As a result, we believe that we do not have sufficient information to reasonably project our future sales in the life science market.

Operating Costs and Expenses. Product costs were $12.2 million (65% of total product sales) for fiscal 2004 compared to $8.0 million (49% of total product sales) for fiscal 2003. Product costs, as a percentage of total product sales, increased in fiscal 2004 due to costs incurred in connection with instrument upgrades (4% of total product sales) and detection module upgrades (17% of total product sales) for existing life science customers. These voluntary upgrades were provided to enhance overall customer satisfaction. The instrument and detection module upgrade programs were substantially completed as of December 31, 2003. Our future profit margin is subject to chance due to a number of uncertainties relating to, among other things, the launch of new instrument systems.

Research and development expenses decreased $3.0 million, or 13%, in fiscal year 2004 to $19.8 million from $22.8 million in fiscal year 2003. This decrease was due primarily to lower personnel and facilities costs for development projects. Research and development expenses primarily relate to ongoing development costs and product enhancements associated with the M-SERIES family of products, development of new assays and research and development of new systems and technologies, including point-of-care products. We expect research and development costs to increase as product development and core research expand, including costs associated with our efforts in developing clinical diagnostics and biodefense testing products, and as we explore other opportunities in the healthcare field.

46

Selling, general and administrative expenses were $18.7 million in fiscal 2004, a decrease of $1.8 million (9%) from the prior year’s total of $20.5 million. This decrease was primarily attributable to lower personnel costs in the current year. Until the completion of the merger and related transactions on February 13, 2004, we were fully integrated with IGEN and the accompanying consolidated financial statements reflect the application of certain estimates and allocations. For periods prior to February 13, 2004, our consolidated statements of operations include all revenues and costs that were directly attributable to our businesses. In addition, certain expenses of IGEN were allocated to us using various assumptions that, in the opinion of management, are reasonable. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue, or percentage of total headcount, or estimates of actual time spent on businesses, as appropriate. These allocated expenses comprise a significant portion of our selling, general and administrative expenses for fiscal 2004.

We incurred certain nonrecurring costs of $75.7 million in connection with the merger and related transactions, which consisted of, an allocated one-time noncash compensation charge of $38.8 million associated with the cancellation of IGEN stock options and the payment of merger consideration for each share of IGEN common stock covered by such stock options, a $33.7 million charge related to the $37.5 million MSD payment made in connection with the merger and related transactions, as well as accounting, legal, printing and registration fees. With respect to employee stock options, the compensation charge is calculated based on the difference between the last trading price of IGEN common stock, which was $64.09 per share, and the exercise price of each employee stock option, including both vested and unvested employee stock options. With respect to nonemployee stock options, the compensation charge is calculated based on the incremental fair value of the nonemployee stock options resulting from the merger and related transactions. With respect to the MSD payment, it was determined that at the time of the payment in February 2004, recording the payment to the Investment in Joint Venture account would result in the value of our investment in MSD being greater than its fair market value. Accordingly, we expensed the amount of the payment that would exceed fair market value. No additional expenses related to the merger and related transactions are expected to be recorded in periods after March 31, 2004.

Since 1995 we have engaged the law firm of Wilmer, Cutler & Pickering to provide legal services. Jennifer M. Drogula, who became the daughter-in-law of our Chief Executive Officer in March 2002, has been a partner of that firm since January 2001. In addition, Mr. Richard Cass, one of IGEN’s directors, was formerly a partner of the firm. We recorded approximately $300,000 and $100,000 in legal fees with the law firm for the years ended March 31, 2004 and 2003, respectively.

We have also engaged the law firm of Hale & Dorr LLP to provide legal services. We first engaged this law firm in 1994. Deborah Wohlstadter, the wife of Jacob Wohlstadter and daughter-in-law of our Chief Executive Officer since December 2001, is a junior partner in that law firm. We recorded approximately $100,000 in legal fees with that law firm for each of the years ended March 31, 2004 and 2003.

Our Chief Executive Officer, Samuel J. Wohlstadter, is the principal and controlling stockholder, a director and the Chief Executive Officer of each of Wellstat Biologics Corporation Wellstat Therapeutics Corporation Hyperion Catalysis International Proteinix Corporation and Integrated Chemical Synthesizers, Inc. Our President and Chief Operating Officer, Richard J. Massey, is also a director of Hyperion and a less than 10% stockholder in Proteinix. These companies are therefore considered our affiliates for the purpose of this discussion.

The Company has shared services arrangements with each of these affiliated companies. These shared services include accounting and finance, human resources and other administrative services, as well as facility related costs and services. Shared services costs allocated to these companies totaled $1.0 million for each of the years ended March 31, 2004 and 2003, which reduced certain Operating Costs and Expenses for the respective years. Amounts allocated to these affiliated companies are calculated and billed monthly based upon costs incurred by us and are determined through allocation methods that include time spent and square footage utilized. The affiliated companies had prepaid approximately $12,000 under the shared services arrangements at March 31, 2004, and the amount due from affiliated companies under the shared services arrangements was approximately

47

$200,000 at March 31, 2003. All such balances were paid subsequent to each respective year end. See ITEM 13-“Certain Relationships and Related Transactions”.

Interest Income and Other Expense. In fiscal 2004, we recorded a $1.2 million non-cash charge representing the value of MSD’s option to purchase our interests in MSD. In addition, interest income, net of interest and other expense, was $267,000 in fiscal 2004 and $154,000 in fiscal 2003. This increase in net interest income resulted from a growth in interest earned in the current year due to a higher balance of invested funds.

Equity in Loss of Joint Venture. Equity in loss of joint venture was $19.6 million and $17.6 million for the years ended March 31, 2004 and 2003, respectively. MSD’s losses increased in fiscal 2004 primarily due to higher costs associated with its transition from a development stage entity to a commercial operating company. The increase in MSD’s losses during the year ended March 31, 2004 results primarily from increases in sales and marketing expenses which were offset only in part by the growth in revenues which commenced in October 2002.

Change in Accounting Principle — Upon implementation of FIN 46, we recorded a one-time, non-cash $33.7 million adjustment to reflect a change in accounting principle, thereby adjusting the book value of our investment in the MSD joint venture to equal the consolidated net assets of MSD. This adjustment is reflected on our consolidated statements of operations as the cumulative effect of a change in accounting principle.

Net Loss. The net loss for fiscal year 2004 was $93.3 million ($3.49 per common share), compared to a net loss of $50.9 million ($1.90 per common share) in fiscal year 2003. The net loss is primarily caused by operating expenses and equity in loss of joint venture exceeding our revenues. The increase in net loss is primarily due to the merger related costs incurred in 2004.

Years Ended March 31, 2003 and 2002

Revenues. Total revenues were $17.8 million for the fiscal year ended March 31, 2003, an increase of approximately $4.6 million or 34% from $13.2 million in fiscal 2002. Product sales were $16.5 million in fiscal 2003, an increase of $4.4 million or 37% from $12.1 million in fiscal 2002. This increase in product sales resulted from sales of products for the life science market of $11.9 million in fiscal 2003, an increase of $1.0 million from $10.9 million in fiscal 2002, and sales of biodefense products of $4.6 million in fiscal 2003, an increase of $3.4 million from $1.2 million in fiscal 2002. Sales of products for the life science market increased due to increased sales of the M-SERIES family of products.

Operating Costs and Expenses. Product costs were $8.0 million (49% of product sales) in fiscal 2003 compared to $5.4 million (44% of product sales) in fiscal 2002. Product costs in fiscal 2002 included a write-off of approximately $1.1 million representing the remaining net book value of the TRICORDER detection modules incorporated into customers’ M-SERIES systems. The cost of these modules had previously been recorded as a fixed asset and depreciated over their estimated useful life, and should have been recorded as product costs upon shipment and sale. We determined that the adjustment did not have a material impact on fiscal 2002 or prior period financial statements and, accordingly, did not revise such financial statements. Of the $1.1 million adjustment, approximately $200,000 is related to fiscal 2002 and the remaining $900,000 is related to prior fiscal years (approximately $400,000 and $500,000 related to fiscal 2001 and 2000, respectively). Excluding the $900,000 write-off, product costs were 37% of product sales in fiscal 2002. Product costs in fiscal 2003, as a percentage of product sales, increased from 37%, as adjusted, to 49% primarily due to costs incurred in connection with instrument upgrades for existing life science customers ($1.1 million or 7% of product sales) and warranty costs in excess of the warranty reserve ($600,000 or 4% of product sales). The voluntary instrument upgrades were provided to enhance overall customer satisfaction.

Research and development expenses were $22.8 million in fiscal 2003, a decrease of $4.0 million or 15% from $26.8 million in fiscal 2002. Of the $26.8 million in fiscal 2002, $2.4 million was spent funding MSD joint venture activities prior to the amendment and extension of the MSD joint venture agreements in August 2001.

48

See “— Equity in Loss of Joint Venture” below for a discussion of activities relating to MSD in fiscal 2003 and 2002. Research and development expenses primarily relate to ongoing development costs and product enhancements associated with the M-SERIES family of products, development of new assays for the life science market and research and development of new systems and technologies, including point-of-care products.

Selling, general and administrative expenses were $20.5 million in fiscal 2003, an increase of $1.3 million or 6% from $19.2 million in fiscal 2002. This increase was primarily attributable to additional personnel and support costs required to support the increase in sales and customers. For each of the periods, we were fully integrated with IGEN and the accompanying consolidated financial statements reflect the application of certain estimates and allocations. Our consolidated statements of operations include all revenues and costs that are directly attributable to our businesses. In addition, certain expenses of IGEN have been allocated to us using various assumptions that, in the opinion of management, are reasonable. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total headcount, as appropriate. There are no other selling, general and administrative expenses for fiscal 2003 and fiscal 2002 other than these allocated expenses.

Since 1995, we have retained Wilmer, Cutler & Pickering to perform legal services. Jennifer M. Drogula, who became the daughter-in-law of our chief executive officer in March 2002, has been a partner of the firm since January 2001. In addition, Mr. Richard Cass, one of IGEN’s directors, was formerly a partner of the firm. We recorded approximately $100,000 and $400,000 in legal fees to the law firm for the years ended March 31, 2003 and 2002, respectively.

We have shared services arrangements with each of the affiliated companies. These shared services include accounting and finance, human resources and other administrative services, as well as facility related costs and services. Shared services costs allocated to these companies totaled $1.0 million and $1.3 million in fiscal 2003 and 2002, respectively, which reduced certain operating costs and expenses for the respective years. Amounts allocated to the affiliated companies are calculated and billed monthly based upon costs incurred by us and are determined through allocation methods that include time-spent and square footage utilized. Amounts due from affiliated companies under these shared services agreements were approximately $200,000 and $100,000 at March 31, 2003 and 2002, respectively, and were paid subsequent to each respective year end. See ITEM 13-“Certain Relationships and Related Transactions”.

Interest Income and Other Expense. Interest income, net of other expense, was approximately $200,000 in fiscal 2003. Interest expense, net of other income, was approximately $39,000 in fiscal 2002. This increase in income was due to foreign currency transaction gains in the fiscal 2003 period.

Equity in Loss of Joint Venture. As discussed above, MSD is a joint venture formed by MST and us in 1995. Beginning on July 1, 2001, MSD was transitioning from a development stage entity to a commercial enterprise and milestones establishing the continued viability of MSD were first achieved in the quarter ended September 30, 2001. For example, prototypes had been assembled demonstrating product feasibility, and MSD was anticipating initial product launch in approximately one year. As a result of this transition, MSD’s expenses were no longer primarily research and development. Accordingly, since July 1, 2001, we have recorded only our proportionate share of MSD losses, representing approximately 100% of MSD’s losses, for each respective period as equity in loss of joint venture consistent with accounting for equity method investments. Equity in loss of joint venture was $17.6 million in fiscal 2003, and $10.9 million in fiscal 2002. In addition, approximately $2.4 million of the fiscal 2002 MSD contributions, all occurring prior to July 1, 2001, were recorded by us as research and development expenses based upon the significance and character of the MSD losses. In connection with entering into the MSD agreements in August 2001, IGEN transferred certain equipment and leasehold improvements to MSD in an amount of approximately $800,000, which amount is included in the in-kind contributions to MSD in such year.

49

MSD’s losses increased in fiscal 2003, primarily due to higher costs associated with its transition from a development stage entity to a commercial operating company. MSD commenced product sales in October 2002, and during the year ended March 31, 2003, its product sales totaled $3.2 million. MSD increased its staffing during fiscal 2003 primarily for development personnel and new sales and marketing personnel to support the launch of its products. These personnel increases resulted in higher costs for both research and development and sales and marketing.

Net Loss. The net loss was $50.9 million in fiscal 2003, an increase of $1.7 million or 4% from the net loss of $49.2 million in fiscal year 2002. This increase was primarily due to higher losses by MSD in fiscal 2003, reflected as an increase in equity in loss of joint venture, offset by the growth in our fiscal 2003 product sales.

Liquidity and Capital Resources

Beginning as of March 31, 2004, we have consolidated the financial results of MSD in accordance with the requirements of FIN 46. Our consolidated balance sheet at March 31, 2004 had cash and cash equivalents of $182.5 million. Of this amount, $35.1 million represented the cash and cash equivalents of MSD. We have no rights or access to these funds or any other capital resources of MSD. The amount of cash and cash equivalents to which we and our wholly-owned subsidiaries have unrestricted use is $147.4 million. In addition, our consolidated balance sheet includes the accounts receivable, inventory and other assets and liabilities of MSD. We have no rights or access to MSD’s assets and we do not have obligations with respect to MSD’s liabilities.

In connection with the merger and related transactions, Roche loaned IGEN approximately $210 million. These funds, less transaction costs of approximately $25 million, were contributed by IGEN as equity to us as part of the merger and related transactions. The related promissory note remained the obligation of IGEN and we have no obligations associated with that debt. Simultaneously with the execution of the merger agreement in connection with the merger and related transactions, we entered into worldwide, non-exclusive PCR license agreements with certain affiliates of Roche. We paid Roche a license fee of $50 million and will also pay royalties on sales of licensed products, royalties for every PCR plasma test we perform or have a laboratory perform and royalties on net service revenue that we receive for diagnostic testing procedures that we perform using PCR technology. We have performed a valuation of the PCR technology licenses and have recorded a value of $19.5 million and reflected a $30.5 million adjustment to the consideration paid by Roche with respect to the merger and related transactions.

Net cash used in operations was $29.6 million, $33.1 million and $34.2 million during the years ended March 31, 2004, 2003 and 2002, respectively. Cash used for operations in 2004 resulted from the net loss, partially offset by adjustments for the equity in loss of joint venture, and a non cash compensation charge related to stock options. Cash used for operations in 2003 resulted from the net loss, offset by an adjustment for the equity in loss of joint venture.

We used approximately $1.9 million, $3.3 million and $5.6 million of cash for the acquisition of equipment and leasehold improvements during the years ended March 31, 2004, 2003 and 2002, respectively. Our investments in MSD totaled $56.7 million (including a $37.5 million payment to MSD following the completion of the merger and related transactions), $20.5 million and $19.6 million for the years ended March 31, 2004, 2003 and 2002, respectively. We also used $50 million during the year ended March 31, 2004 for acquisition of the PCR license, as discussed above.

We believe that material commitments for capital expenditures and additional or expanded facilities may be required in a variety of areas, such as product development programs. We have not, at this time, made material commitments for any such capital expenditures or facilities and have not secured additional sources, if necessary, to fund such commitments.

Under the tax allocation agreement associated with the merger and related transactions, Roche and IGEN will be solely liable for, will jointly and severally indemnify us against, and will be entitled to receive and retain all refunds of, taxes (other than transfer taxes) directly or indirectly resulting from, arising in connection with or

50

otherwise related to the merger and related transactions, any transaction undertaken to prepare for the merger and related transactions and any of the actions taken pursuant to the ongoing litigation agreement. This agreement also provides that we were required to pay IGEN a $20 million distribution gain payment. This amount was calculated based on the average of the high and low trading prices of our common stock on the first day of trading of our common stock after the completion of the merger, exceeding a specified threshold. The $20 million distribution gain amount was recorded as a liability on our balance sheet at March 31, 2004 and payment was made by us subsequent to March 31, 2004.

Net cash provided by financing activities, excluding the consolidation of MSD’s cash and cash equivalents in 2004, was $255.1 million, $57.0 million and $56.3 million for the years ended March 31, 2004, 2003 and 2002, respectively. The financing activity for the year ended March 31, 2004 was primarily related to the funding provided by IGEN in conjunction with the merger and related transactions, as well as the sale of $7.5 million of Series B preferred stock to Samuel J. Wohlstadter, our Chairman and Chief Executive Officer. Under the terms of the Series B preferred stock, we may redeem the Series B preferred stock at $0.01 per share at any time we are no longer entitled to receive distributions with respect to our class C interests in MSD. We will redeem a proportionate part of the Series B preferred stock in connection with any redemption by MSD of the class C interests held by us described in the previous sentence. No distributions on the Series B preferred stock will be paid unless and until distributions are paid on such class C interests in accordance with the MSD limited liability company agreement, in which event distributions on the Series B preferred stock will be paid in the same manner and amount as such distributions on the class C interests. In connection with the settlement, we received a $2.0 million non-refundable pre-payment from MSD for future amounts payable by MSD to us pursuant to the buy-out of our interest in MSD. The holder of our Series B preferred stock will be entitled to a pro-rata share, representing the proportionate amount of our class C interest in MSD that was funded by the sale of Series B preferred stock, of the portion of the $2.0 million that is allocable to our class C interests.

As of March 31, 2004, our material future obligations were as follows:

Under the MSD agreements, IGEN’s funding commitment was based on an annual budget of MSD approved by the JVOC. The JVOC approved funding for MSD for the period from January 1, 2003 to November 30, 2003 in an amount of $20.6 million, subject to a permitted variance of 15%, of which approximately $19.1 million was spent by MSD and funded by us. MSD asserted that we were obligated to pay MSD up to an additional $4.6 million, which is the difference between the amount spent by MSD and the budgeted amount plus the permitted variance. As part of the settlement, we agreed to pay MSD the net amount of $3.0 million which represents full and complete satisfaction of amounts due to MSD pursuant to the MSD agreements, including this dispute regarding unsatisfied committed funding obligations, certain intellectual property matters, and the

51

previously outstanding dispute regarding the payment of certain legal fees and expenses incurred by MSD in connection with its participation and involvement in the merger and related transactions. Our $3.0 million payment is net of a $2.0 million non-refundable pre-payment by MSD to us for future amounts payable by MSD to us pursuant to the buy-out of our interest in MSD. The amount of the pre-payment credit outstanding from time to time shall bear simple interest (cumulated, not compounded) at the fixed annual rate of 0.5% over the prime rate in effect on the date that MSD or MST, as the case may be, purchases our interests in MSD. The amount of the outstanding credit balance of the prepayment credit, including accrued interest, shall be reduced for amounts due and payable to us pursuant to the buy-out of our interest in MSD and no further cash payments will be payable by MSD to us until the $2.0 million prepayment credit, including accrued interest, is utilized. A total of $5.0 million is to be treated as a Class C capital contribution. There is no assurance that we will be able to realize any value from this additional contribution.

For the years ended March 31, 2004, 2003 and 2002 total contributions to MSD were $56.7 million, $20.5 million and $19.6 million, respectively, including $3.7 million in the year ended March 31, 2004, which constituted discretionary funding related to the permitted budget variances from prior years. The funding commitment was satisfied in part through in-kind contributions of scientific and administrative personnel and shared facilities. In accordance with the MSD joint venture agreement, the value of these in-kind contributions is based upon costs incurred by us as determined through allocation methods that include time-spent and square footage utilized. During years ended March 31, 2004, 2003 and 2002, operating costs allocated to MSD in connection with shared personnel and facilities totaled $6.0 million, $11.9 million and $11.4 million, respectively. In fiscal 2005, we made payments to MSD in connection with the settlement as described in the preceding paragraph. We have no intention to provide additional funding to MSD.

As noted above, MSD or MST will purchase our interest in MSD for a purchase price equal to fair market value less a discount of 7.5%, with fair market value to be determined by an appraisal process. The current book value of our investment is $46.2 million. There is no assurance that the purchase price will enable us to recover the book value of our investment. In addition, because the purchase price is payable in installments from a percentage of future MSD net sales or financings, there is no assurance that we will receive all or any portion of the purchase price, other than the $2.0 million prepayment credit we received in connection with the settlement.

Product development for our clinical diagnostic products is at an early development stage and products based on the PCR technology being licensed from Roche are not yet under development. Product development is subject to a number of technical and commercial uncertainties and in part depends upon our ability to enter into new collaborative arrangements. Accordingly, we have not yet completed a business plan for our clinical diagnostic products, including immunodiagnostic and PCR technology-based products, do not have definitive product introduction timelines or budgets and have not determined the additional funding, personnel, facilities, equipment or technology that may be required to implement our plans.

Our ability to become profitable in the future will depend on, among other things, the introduction of new products to the market. If we are unable to develop new products, including products based on PCR technology, our business prospects and financial results would be adversely affected.

Furthermore, we will need substantial amounts of money to fund our operations on an ongoing basis. We expect our available cash to be sufficient to fund our operations for at least one year, but we cannot predict how long our available cash will be sufficient to fund our operations thereafter. In this regard, we expect that we will from time to time have discussions with third parties, including multinational corporations, regarding various business arrangements including distribution, marketing, research and development, joint venture and other business agreements, which could provide for substantial up-front fees or payments.

We cannot assure you that we will successfully complete any of the foregoing arrangements and access to funds could be adversely impacted by many factors, including the volatility of the price of our common stock, continuing losses from our operations, establishment of new business arrangements, the status of new product launches, general market conditions and other factors. If we are unable to raise additional capital, we may have to scale back, or even eliminate, some programs. Alternatively, we may consider pursuing arrangements with other companies, such as granting licenses or entering into joint ventures or collaborations, on terms that may not be favorable to us.

As of March 31, 2004, we had no special purpose entities.

Critical Accounting Policies

52

A critical accounting policy is one that is both important to the portrayal of our financial position and results of operations and requires the application of difficult, subjective or complex judgments by management. As a result, critical accounting policies are subject to an inherent degree of uncertainty.

In applying those policies, management uses its judgment to determine the appropriate assumptions to be used in the determination of certain estimates. These estimates are based on our management’s experience, terms of existing contracts, observance of trends in the industry, information provided by customers, and information available from other outside sources, as appropriate. Our critical accounting polices include:

Expense Allocations — Prior to February 13, 2004, our assets and businesses were owned, operated and fully integrated with IGEN. Our financial statements have been prepared and are presented as if we had been operating as a separate entity during the periods shown. In order to fairly present our operating results, these financial statements reflect the application of certain estimates and allocations for periods prior to February 13, 2004. For such periods, our consolidated statements of operations include all costs that were directly attributable to our businesses, as well as certain expenses of IGEN that were allocated to us using various assumptions. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs) which were allocated based upon percentage of total revenue or percentage of total headcount, as appropriate. While management believes that the allocation methodologies are reasonable and appropriate, different allocation methodologies could result in changes to our operating results.

Revenue Recognition — We derive revenue principally from three sources: product sales, royalty income and contract fees. Product sales revenue is generally recognized when persuasive evidence of an arrangement exists, the price to the buyer is fixed and determinable, collectibility is reasonably assured and the product is shipped to the customers thereby transferring title and risk of loss. For instrument sales, the instrument and the related installation are considered to be separate elements under EITF 00-21. Revenue is recognized for the instrument upon shipment and is recognized for the installation when complete based upon the residual value method. For instrument and reagent sales, there is no option of return and refund, only the option to repair or replace. Other than the installation required for the instruments, there are no contingencies, allowances or other post-sale obligations. For instrument leases, the instrument rental and related minimum reagent purchases are considered to be separate elements under EITF 00-21 and, accordingly, the sales price is allocated to the two elements based upon their relative fair values. Instrument rental revenue is recognized ratably over the life of the lease agreements and the related reagent revenue is recognized upon shipment. Revenue associated with extended warranty arrangements is recognized over the term of the extended warranty contract. Royalty income is recorded when earned, based on information provided by licensees.

Revenue from services performed under contracts is recognized when obligations under the contract have been satisfied. The satisfaction of obligations may occur over the term of the underlying customer contract, if the contract is based on the achievement of certain “milestones,” or may occur at the end of the underlying customer contract, if based only upon delivery of the final work product.

The majority of our product sales and contract fees contain standard terms and conditions. Certain transactions may contain negotiated terms that require contract interpretation to determine the appropriate amount of revenue to be recognized. In addition, we must assess whether collectibility is reasonably assured. While management believes its interpretations and judgments are reasonable, different assumptions could result in changes in the timing of revenue recognition.

Joint Venture Accounting — For periods prior to March 31, 2004, we accounted for our ownership in the MSD joint venture on the equity method, as we have determined that we do not control MSD’s operations. Factors considered in determining our level of control include the fact that we have less than 50% of the voting equity interest in MSD; that we do not have exclusive authority over MSD decision making and have no ability to unilaterally modify the joint venture agreements; and that we had the right, prior to the Settlement, to appoint only one out of two seats on MSD’s board of managers. A different assessment of these factors could have provided for the use of consolidation accounting rather than the equity method, in which case a consolidation of

53

our financial statements with those of MSD would have been appropriate. Consolidation accounting would have required certain reclassifications within our consolidated financial statements but would not have materially affected our financial position or net loss. See ITEM 8-“Consolidated Financial Statements-Notes to Consolidated Financial Statements — Note 4 — Meso Scale Diagnostics Joint Venture.”

In January 2003, the FASB issued Interpretation No. 46, “Consolidation of Variable Interest Entities,” or FIN 46. FIN 46 provides guidance on variable interest entities such as the MSD joint venture and the framework through which an enterprise assesses consolidation of a variable interest entity. We have adopted FIN 46 as of March 31, 2004 and have determined that MSD qualifies as a variable interest entity based upon the following rationale:

Accordingly, beginning as of March 31, 2004 we have consolidated the financial results of MSD. Under the transition guidance of FIN 46, because MSD was created before February 1, 2003, we have measured the assets, liabilities and noncontrolling interests of MSD as of March 31, 2004 for purposes of the initial consolidation. The amounts of the assets, liabilities and noncontrolling interests are reflective of their respective carrying amounts had FIN 46 been effective when we first met the conditions to be the primary beneficiary of MSD upon MSD’s inception in 1995. We have historically recorded approximately 100% of MSD’s losses. In connection with the merger and related transactions, we made a $37.5 million payment to MSD. We determined that at the time of the payment, recording the entire payment to the investment in joint venture account would result in the book value of the Company’s investment in MSD being greater than its fair value. Accordingly, we expensed $33.7 million, which represents the amount of the payment that gave rise to its net recorded investment exceeding the fair market value of its interests. Upon implementation of FIN 46, we recorded a one-time, non-cash $33.7 million adjustment to reflect this change in accounting principle. The balance sheet as of March 31, 2004 reclassified amounts formerly recorded on a “net” basis as investment in joint venture to be reflected on a “gross” basis primarily as cash, accounts receivable, inventory, fixed assets, accounts payable and accrued expenses. The statement of operations for periods subsequent to March 31, 2004 will reclassify amounts formerly recorded on a “net” basis as equity in loss of joint venture to be reflected on a “gross” basis primarily as revenue, product costs, research and development expenses and selling, general and administrative expenses. Historical financial information of MSD is summarized in Note 4 of our consolidated financial statements and the audited MSD financial statements are included elsewhere in this Form 10-K.

Inventory — We record our inventory at the lower of cost or market using the first-in, first-out method. We regularly review inventory quantities on hand and record a reserve for excess and obsolete inventory based primarily on an estimated forecast of product demand and production requirements for the next twelve months. Reserves are recorded for the difference between the cost and the market value.

Those reserves are based on significant estimates. Our estimates of future product demand may prove to be inaccurate, in which case we may have understated or overstated the provision required for excess and obsolete inventory. In addition, our industry is characterized by technological change, frequent new product development and product obsolescence that could result in an increase in the amount of obsolete inventory quantities on hand. Although we make every effort to ensure the accuracy of our forecasts of future product demand, any significant unanticipated changes in demand or technological developments could have a significant impact on the values of our inventory and our reported operating results.

Evaluation of Long-lived Assets — We have different long-lived assets recorded on our balance sheet that include equipment and leasehold improvements, investments, licenses and other assets. We evaluate the potential impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. In evaluating the recoverability of an asset,

54

management’s policy is to compare the carrying amount of an asset with the projected undiscounted cash flow. While management believes that its projections are reasonable and that no impairment of these assets exists, different assumptions could affect these evaluations and result in impairment charges against the carrying value of these assets.

Warranty Reserve — We warrant our products against defects in material and workmanship for one year after sale and record estimated future warranty costs at the time revenue is recognized. A reserve for future warranty claims is recorded based upon management’s review of historical results, supplemented by expectations of future costs. Unanticipated changes in actual warranty costs could impact our operating results.

Recent Accounting Pronouncements

See discussion of FASB Interpretation No. 46, “Consolidation of Variable Interest Entities,” under “-Critical Accounting Policies” above.

In April 2003, the FASB issued SFAS No. 149, “Amendment of SFAS No. 133 on Derivative Instruments and Hedging Activities,” or SFAS 149. SFAS 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.” The amendments set forth in SFAS 149 require that contracts with comparable characteristics be accounted for similarly. SFAS 149 is generally effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. The implementation of SFAS 149 did not have a material effect on our financial position, results of operations or cash flows.

In May 2003, the FASB issued SFAS No. 150 “Accounting for Certain Financial Instruments with Characteristics of Both Liability and Equity,” or SFAS 150. SFAS 150 establishes standards regarding the classification and measurement of certain financial instruments with characteristics of both liabilities and equity. SFAS 150 is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. The implementation of SFAS 150 did not have a material effect on our financial position, results of operations or cash flows. On February 17, 2004, we issued $7.5 million Series B preferred stock, and we concluded that such financial instrument did not meet the definition of a liability under SFAS 150.

ITEM 7A.       QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Prior to the completion of the merger and related transactions on February 13, 2004, our assets and businesses were owned and operated by IGEN. IGEN held all cash in a centralized treasury and provided all of the necessary funding for our operations. Accordingly, no cash is reflected on our consolidated balance sheets prior to February 13, 2004.

We are exposed to changes in exchange rates where we sell direct in local currencies, primarily in the United Kingdom and Germany. Certain other foreign sales are denominated in U.S. dollars and have no exchange rate risk. Gains and losses resulting from foreign currency transactions have historically not been material.

Beginning as of March 31, 2004, we have consolidated the financial results of MSD in accordance with the requirements of FIN 46. Our consolidated balance sheet at March 31, 2004 had cash and cash equivalents of $182.5 million. Of this amount, $35.1 million represented cash and cash equivalents of MSD. We have no rights or access to these funds. The amount of cash and cash equivalents to which we and our wholly-owned subsidiaries have unrestricted use is $147.4 million, which is 63.3% of total consolidated assets at March 31, 2004.

We invest excess cash in accordance with a policy approved by our Board of Directors. The policy is designed to provide both liquidity and safety of principal. The policy limits investments to certain types of instruments issued by institutions with strong investment grade credit ratings and places restrictions on our investments by

55

terms and concentrations by type and issuer. We invest our excess cash in money market funds, securities of the U.S. Treasury, and certificates of deposit with original maturities of three months or less.

Our invested cash is sensitive to changes in the general level of interest rates. Based on our cash and cash equivalents balance at March 31, 2004, a 100 basis point movement in interest rates would have an approximately $1.5 million impact on our annual interest income and annual net loss. Actual changes in rates may differ from the hypothetical assumption used in computing this exposure.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.     ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

On February 13, 2004, IGEN International, Inc. (IGEN or Parent) and Roche Holding Ltd (Roche) consummated a transaction pursuant to which Roche acquired IGEN and IGEN simultaneously distributed the common stock of BioVeris Corporation (the Company), to its stockholders (the merger). The transaction occurred in the following steps:

The Company was organized as IGEN Integrated Healthcare, LLC, a Delaware limited liability company, on June 6, 2003, and converted into BioVeris Corporation, a newly formed Delaware corporation on September 22, 2003.

Simultaneous with the execution of the merger, the Company entered into worldwide, non-exclusive PCR license agreements with certain affiliates of Roche. One agreement grants the Company rights to make, import, use and sell certain PCR products within specified fields, while the other agreement grants the Company rights to perform certain PCR services within specified fields. The Company paid Roche a license fee of $50 million and will also pay royalties on sales of licensed products, royalties for every PCR plasma test it performs or has a laboratory perform and royalties on net service revenue that the Company receives for diagnostic testing procedures that it performs using PCR technology. The Company has performed a valuation of the PCR technology licenses and has recorded a value of $19.5 million and reflected a $30.5 million adjustment reducing the amount recorded for consideration paid by Roche with respect to the merger and related transactions.

The tax allocation agreement executed in conjunction with the merger and related transactions provides that Roche and IGEN will be solely liable for, will jointly and severally indemnify the Company against, and will be entitled to receive and retain all refunds of, taxes (other than transfer taxes) directly or indirectly resulting from, arising in connection with or otherwise related to the merger and related transactions, any transaction undertaken to prepare for the merger and related transactions and any of the actions taken pursuant to the ongoing litigation agreement. This agreement also provides that the Company was required to pay IGEN a $20 million distribution gain payment. This amount was calculated based on the average of the high and low trading prices of the Company’s common stock on the first day of trading of the Company’s common stock after the completion of the merger, exceeding a specified threshold. The distribution gain accrual is recorded on the Company’s balance sheet at March 31, 2004 and an adjustment was made to the consideration paid by Roche with respect to the merger and related transactions. The distribution gain payment was made by the Company subsequent to March 31, 2004.

Prior to the completion of the merger and related transactions, the assets and businesses of the Company had historically been owned and operated by IGEN and IGEN held all cash in a centralized treasury, providing all of the necessary funding for the operations of the Company. The accompanying financial statements have been prepared and are presented as if the Company had been operating as a separate entity using IGEN’s historical cost basis in the assets and liabilities and including the historical operations of the businesses and assets transferred to the Company from IGEN as part of the restructuring. Results of operations and cash flows for the year ended March 31, 2004 include its business through February 13, 2004 while it was owned and operated by

63

IGEN, and the period from February 14, 2004 through March 31, 2004 when it operated as an independent entity.

In connection with the merger and related transactions, Roche loaned IGEN approximately $210 million. These funds, less transaction costs of approximately $25 million, were contributed by IGEN as equity to us as part of the merger and related transactions. The related promissory note remained the obligation of IGEN and we have no obligations associated with that debt. Accordingly, prior to the completion of the merger and related transactions, IGEN’s net investment in the Company is shown in lieu of stockholders’ equity in the accompanying consolidated balance sheets and no cash is reflected on the accompanying consolidated balance sheets.

For each of the periods presented in the consolidated financial statements prior to the completion of the merger and related transactions, the Company was fully integrated with IGEN and these financial statements reflect the application of certain estimates and allocations. The Company’s consolidated statements of operations include all revenues and costs that are directly attributable to the Company’s businesses. In addition, certain expenses of IGEN have been allocated to the Company using various assumptions. These expenses include an allocated share of general and administrative salaries as well as certain other shared costs (primarily facility, human resources, legal, accounting and other administrative costs). General and administrative salaries have been allocated primarily based upon an estimate of actual time spent on the businesses of the Company. Facilities costs and centralized administrative services have been allocated based upon a percentage of total product sales as well as a percentage of total headcount. Allocated expenses of $15.7 million, $20.5 million and $19.2 million are included in selling, general and administrative expenses in the accompanying consolidated statements of operations for the years ended March 31, 2004, 2003 and 2002, respectively. These allocated expenses were derived from total IGEN selling, general and administrative expenses of $22.3 million, $24.7 million and $24.0 million for the years ended March 31, 2004, 2003 and 2002, respectively. In addition, certain merger related costs have been allocated to the Company based upon an estimate of actual time spent by professional service providers (see Note 2 to consolidated financial statements for discussion of other allocated merger costs). Management believes these allocation methodologies and estimations are reasonable based upon the nature of the related expenses and management’s knowledge of the level of effort and space required to support the businesses of the Company. The financial information included herein may not be indicative of the financial position, results of operations and cash flows of the Company in the future or what they would have been had the Company been operating as a stand-alone entity in the past.

Consolidation Accounting — The consolidated financial statements include the accounts of the Company and its subsidiaries. In addition, the Company adopted FIN 46 as of March 31, 2004 and has determined that MSD qualifies as a variable interest entity and the Company is the primary beneficiary. Accordingly, beginning March 31, 2004, the Company has consolidated the financial results of MSD. All significant intercompany transactions and balances have been eliminated.

Change in Accounting Principle — Under the transition guidance of FIN 46, because MSD was created before February 1, 2003, the Company has measured the assets, liabilities and noncontrolling interests of MSD as of March 31, 2004 for purposes of the initial consolidation. The amounts of the assets, liabilities and noncontrolling interests are reflective of their respective carrying amounts had FIN 46 been effective when the Company first met the conditions to be the primary beneficiary of MSD upon MSD’s inception in 1995. The Company has historically recorded approximately 100% of MSD’s losses. In connection with the merger and related transactions, the Company made a $37.5 million payment to MSD. The Company determined that at the time of the payment, recording the entire payment to the investment in joint venture account would result in the book value of the Company’s investment in MSD being greater than its fair market value. Accordingly, the Company expensed $33.7 million, which represents the amount of the payment that gave rise to its net recorded investment exceeding the fair market value of its interests. Upon implementation of FIN 46, the Company recorded a one-time, non-cash $33.7 million adjustment to reflect this change in accounting principle, thereby adjusting the book value of the Company’s investment in the MSD joint venture to equal the consolidated net assets of MSD.

64

The balance sheet reclassified amounts formerly recorded on a “net” basis as investment in joint venture to be reflected on a “gross” basis primarily as cash, accounts receivable, inventory, fixed assets, accounts payable and accrued expenses. In fiscal 2005, the statement of operations will reclassify amounts formerly recorded on a “net” basis as equity in loss of joint venture to be reflected on a “gross” basis primarily as revenue, product costs, research and development expenses and selling, general and administrative expenses. The historical financial information of MSD is summarized in Note 4 of our consolidated financial statements.

Estimates — In addition to the estimates noted above, the preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Cash and Cash Equivalents — Cash and cash equivalents include cash in banks, money market funds, securities of the U.S. Treasury, and certificates of deposit with original maturities of three months or less. The Company has invested its excess cash generally in securities of the U.S. Treasury, money market funds, certificates of deposit and corporate bonds. The Company invests its excess cash in accordance with a policy approved by the Company’s Board of Directors. This policy is designed to provide both liquidity and safety of principal. The policy limits investments to certain types of instruments issued by institutions with strong investment grade credit ratings and places restrictions on the Company’s investment by terms and concentrations by type and issuer.

Concentration of Credit Risk — The Company has not experienced any losses on its investments due to credit risk. During the years ended March 31, 2004, 2003 and 2002, agencies of the U.S. government accounted for 22%, 26% and 11% of total revenue, respectively, and 26% and 43% of total consolidated accounts receivable as of March 31, 2004 and 2003, respectively. Additionally, one commercial customer accounted for 18% of total consolidated accounts receivable as of March 31, 2004.

Allowance for Doubtful Accounts — The Company maintains reserves on customer accounts where estimated losses may result from the inability of its customers to make required payments. These reserves are determined based on a number of factors, including the current financial condition of specific customers, the age of accounts receivable balances and historical loss rates.

Inventory — Inventory is recorded at the lower of cost or market using the first-in, first-out method and consists of the following:

Equipment and Leasehold Improvements — Equipment and leasehold improvements are carried at cost, less accumulated depreciation and amortization. Depreciation on equipment, which includes lab instruments and furniture, is computed over the estimated useful lives of the assets, generally three to five years, using straight-line.

65

Leasehold improvements are amortized on a straight-line basis over the life of the lease. Equipment and leasehold improvements consist of the following:

Technology Licenses — Simultaneous with the execution of the merger, the Company entered into worldwide, non-exclusive PCR license agreements with certain affiliates of Roche. One agreement grants the Company rights to make, import, use and sell certain PCR products within specified fields, while the other agreement grants the Company rights to perform certain PCR services within specified fields. The Company paid Roche a license fee of $50 million and will also pay royalties on sales of the licensed products in the licensed fields and on any instrument, accessory, device or system sold for use with the licensed products in the licensed fields at royalty rates ranging from 3% to 20% of net sales, depending on the field, the year, the country of sale and the patents covering such products. It will also pay royalties of $16 or $25 for every PCR plasma test it performs or has a laboratory perform and royalties ranging from 5% to 20% of net service revenue that the Company receives for diagnostic testing procedures that it performs using PCR technology. The Company has performed a valuation of the PCR technology licenses and has recorded their value of $19.5 million and reflected a $30.5 million adjustment reducing the amount recorded for consideration paid by Roche with respect to the merger and related transactions. These licenses are being amortized over an estimated useful life of ten years which is based upon a consideration of the range of patent lives and the weighted average remaining life of the most important underlying patents, as well as a consideration of technological obsolescence and product life cycles. Amortization expense and accumulated amortization was $244,000 for the year ended and at March 31, 2004. Amortization expense is expected to approximate $2.0 million for each year through March 31, 2009.

Evaluation of Long-lived Assets — The Company evaluates the potential impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be fully recoverable. In evaluating the recoverability of an asset, management’s policy is to compare the carrying amount of an asset with the projected undiscounted future cash flow. Management believes no impairment of these assets exists as of March 31, 2004.

Warranty Reserve — The Company warrants its products against defects in material and workmanship for one year after sale and records estimated future warranty costs at the time revenue is recognized. A reserve for future warranty claims is recorded based upon management’s review of historical claims, supplemented by

66

expectations of future costs. The Company also offers extended warranty arrangements to customers, for which related costs are recorded as incurred.

Warranty reserve activity is as follows:

MSD had no warranty reserve at March 31, 2004.

Other Current Assets- Other current assets includes certain assets of MSD aggregating $1.5 million that represent automobiles and deposits on real property. On June 17, 2004, MSD received $2.9 million from Jacob Wohstadter as consideration for the proposed sale by MSD of real property and automobiles, pending approval by the Board of Managers. Jacob Wohlstadter also assumed MSD’s purchase obligations with respect to a prospective real property purchase in the approximate amount of $4.1 million. In August 2004, MSD transferred the real property and automobiles and MSD’s limited liability company interests to Jacob Wohlstadter.

Fair Value of Financial Instruments — The carrying amounts of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable and accrued expenses, approximate their fair value due to their short maturities.

Comprehensive Loss- Comprehensive loss is comprised of net loss and other items of comprehensive loss. Other comprehensive loss includes unrealized losses on “available for sale” securities that are excluded from net loss. There were no significant elements of comprehensive loss for the years ended March 31, 2004, 2003 and 2002.

Revenue Recognition — The Company derives revenue principally from three sources: product sales, royalty income and contract fees.

Product sales revenue is recognized when persuasive evidence of an arrangement exists, the price to the buyer is fixed and determinable, collectibility is reasonably assured and the product is shipped to the customer thereby transferring title and risk of loss. For instrument sales, the instrument and the related installation are considered to be separate elements under EITF 00-21 “Accounting for revenue arrangements with multiple deliverables” . Revenue is recognized for the instrument upon shipment and is recognized for the installation when complete based upon the residual value method. For instrument and reagent sales, there is no option of return and refund, only the option to repair or replace the product. Other than the installation required for the instruments, there are no contingencies, allowances or other post-sale obligations. For instrument leases, the instrument rental and related minimum reagent purchases are considered to be separate elements under EITF 00-21 and, accordingly, the sales price is allocated to the two elements based upon their relative fair values. Instrument rental revenue is recognized ratably over the life of the lease agreements and the related reagent revenue is recognized upon shipment. Revenue associated with extended warranty arrangements is recognized over the term of the extended warranty contract.

Royalty income is recorded when earned, based on information provided by licensees.

67

Revenue from services performed under contracts is recognized when obligations under the contract have been satisfied. The satisfaction of obligations may occur over the term of the underlying customer contract, if the contract is based on the achievement of certain “milestones,” or may occur at the end of the underlying customer contract, if based only upon delivery of the final work product.

Research and Development — Research and development costs are expensed as incurred.

Merger Related Costs — Merger related costs for the year ended March 31, 2004 included the following (in thousands):

With respect to the MSD payment, it was determined that at the time of the payment in February 2004, recording the payment to the Investment in Joint Venture account would result in the value of the Company’s investment in MSD being greater than its fair market value. Accordingly, the Company expensed the amount of the payment that would exceed fair market value. See Note 1- Change In Accounting Principle for the accounting treatment under FIN 46.

Foreign Currency — Gains and losses from foreign currency transactions such as those resulting from the settlement of foreign receivables or payables, are included in the results of operations as incurred. These amounts were not material during the years ended March 31, 2004, 2003 and 2002.

Income Taxes - Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. A valuation allowance is established when necessary to reduce deferred tax assets to the amount expected to be realized.

Stock-based Compensation — The Company has elected to follow the recognition and measurement principles of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations in accounting for employee stock options and, accordingly, will not recognize compensation cost for options granted under its 2003 Stock Incentive Plan whose exercise price equaled the market value of a share of the underlying common stock on the date of grant.

The following table illustrates the effect on net loss and net loss per share as if the Company had applied the fair value recognition provisions of SFAS No. 123, “Accounting for Stock-Based Compensation” as amended by SFAS 148, “Accounting for Stock-Based Compensation — Transition and Disclosure — An Amendment of SFAS 123” to stock-based employee compensation (in thousands, except per share amounts):

68

All per share information for the Company is based on the number of shares of common stock of the Company outstanding upon completion of the merger and related transactions. The net loss, pro forma, and net loss per share, pro forma, disclosed above are not representative of the effects on net loss and net loss per share on a pro forma basis in future years, as future years may include grants by the Company of options for the Company common stock. In addition, information for the years ended March 31, 2003 and 2002 represent options for IGEN common stock which were canceled upon completion of the merger.

The fair value BioVeris options for the year ended March 31, 2004 was estimated at the date of grant using a Black-Scholes option pricing model with the following assumptions:

Based on this calculation, the weighted average fair value of BioVeris options granted during the year ended March 31, 2004 was $5.97. The Company did not have a stock option plan prior to September 2003.

The fair value of IGEN options of each of the years ended March 31, 2003 and 2002 was estimated at the date of grant using Black-Scholes option pricing model with the following assumptions:

Based on this calculation, the weighted average fair value of IGEN options granted was $20.56 and $15.68 during the years ended March 31, 2003 and 2002.

Loss Per Share - The Company uses SFAS No. 128 “Earnings per Share” for the calculation of basic and diluted earnings (loss) per share. For each of the three years ended March 31, 2004, the Company incurred a net loss; therefore, net loss per common share does not reflect the potential dilution that could occur to common shares related to outstanding stock options. For the years ended March 31, 2003 and 2002, the pro forma net loss per share is based on the number of common shares outstanding upon completion of the merger and related transactions. The Company incurred a loss for the year ended March 31, 2004 and, accordingly, did not assume exercise of 20,300 options because to do so would have been anti-dilutive.

New Accounting Standards —In January 2003, the FASB issued Interpretation No. 46, “Consolidation of Variable Interest Entities,” or FIN 46. FIN 46 provides guidance on variable interest entities such as the MSD joint venture and the framework through which an enterprise assesses consolidation of a variable interest entity. The Company adopted FIN 46 as of March 31, 2004 and has determined that MSD qualifies as a variable interest entity based upon the following rationale:

69

Accordingly, beginning March 31, 2004, the Company has consolidated the financial results of MSD. See Note 1 — “Consolidation Accounting and Change in Accounting Principle” for a further discussion of the consolidation of MSD’s financial results.

In April 2003, the FASB issued SFAS No. 149, “Amendment of SFAS No. 133 on Derivative Instruments and Hedging Activities” (SFAS 149). SFAS 149 amends and clarifies financial accounting and reporting for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities under SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities.” The amendments set forth in SFAS 149 require that contracts with comparable characteristics be accounted for similarly. SFAS 149 is generally effective for contracts entered into or modified after June 30, 2003 and for hedging relationships designated after June 30, 2003. The implementation of SFAS 149 did not have a material effect on the Company’s financial position, results of operations or cash flows.

In May 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of Both Liabilities and Equity” (SFAS 150). SFAS 150 establishes standards regarding the classification and measurement of certain financial instruments with characteristics of both liabilities and equity.

SFAS 150 is effective for financial instruments entered into or modified after May 31, 2003, and otherwise is effective at the beginning of the first interim period beginning after June 15, 2003. In February 17, 2004, we issued $7.5 million Series B preferred stock, and we concluded that such financial instrument did not meet the definition of a liability under SFAS 150.

Liquidity — The Company’s consolidated balance sheet at March 31, 2004 had cash and cash equivalents of $182.5 million. Of this amount, $35.1 million represented the cash and cash equivalents of MSD. The Company has no rights or access to these funds or any other capital resources of MSD. The amount of cash and cash equivalents to which the Company and its wholly-owned subsidiaries had unrestricted use is $147.4 million. In addition, the Company’s consolidated balance sheet includes the accounts receivable, inventory and other assets and liabilities of MSD. The Company has no rights or access to MSD’s assets and the Company does not have obligations with respect to MSD’s liabilities.

Product development for the Company’s clinical diagnostic products is at an early development stage and products based on the PCR technology being licensed from Roche are not yet under development. Product development is subject to a number of technical and commercial uncertainties and in part depends upon the Company’s ability to enter into new collaborative arrangements. Accordingly, the Company has not yet completed a business plan for its clinical diagnostic products, and it does not have definitive product introduction timelines or budgets and has not determined the additional funding, personnel, facilities, equipment or technology that may be required to implement its plans.

The Company’s ability to become profitable in the future will depend on, among other things, the introduction of new products to the market. If the Company is unable to develop new products, its business prospects and financial results would be adversely affected.

2.     STOCKHOLDERS’ EQUITY

Series B Preferred Stock — In February 2004, the Company issued 1,000 shares of its Series B preferred stock to its chairman and chief executive officer for $7.5 million. The Series B preferred stock economically mirrors the class C interest in MSD (see Note 4) that is held by the Company. Under the terms of the Series B preferred stock, the Company may redeem the Series B preferred stock for $0.01 per share at any time it is no longer

70

entitled to receive distributions with respect to the class C interests in MSD, pursuant to the MSD limited liability company agreement. The Company will redeem a proportionate part of the Series B preferred stock in connection with any redemption by MSD of the class C interests held by the Company in MSD described in the previous sentence. No distributions on the Series B preferred stock will be paid unless and until distributions are paid on such class C interests in accordance with the MSD limited liability company agreement, in which event distributions on the Series B preferred stock will be paid in the same manner and amount as such distributions on the class C interests. The shares of the Company’s Series B preferred stock are entitled in the aggregate to 1,000 votes on all matters on which holders of the Company’s common stock may vote. In addition, the Company may not consent to any adverse change to the terms of the class C interests in MSD described in this paragraph without the consent of the holders of the Series B preferred stock.

In connection with an August 2004 agreement between the Company and MSD, the Company received a $2.0 million non-refundable pre-payment from MSD for future amounts payable by MSD to it pursuant to the buy-out of its interest in MSD. The holder of the Company’s Series B preferred stock will be entitled to a pro-rata share, representing a proportionate amount of the Company’s class C interest in MSD that was funded by the sale of the Series B preferred stock, of the portion of the $2.0 million that is allocable to our class C interests.

Stock Option Plan — In September 2003, the Board of Directors of the Company adopted the 2003 Stock Incentive Plan (Stock Plan) under which 5.3 million shares of common stock have been reserved for issuance upon exercise of options granted to employees, non-employee directors or consultants of the Company and its subsidiaries. The Stock Plan was approved by an affirmative vote of the IGEN stockholders prior to the completion of the merger.

The Stock Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the Internal Revenue Code of 1986, as amended, non-statutory stock options, restricted stock awards and other stock-based awards, including the grant of shares based upon certain conditions, the grant of securities convertible into common stock of the Company and the grant of stock appreciation rights. Incentive stock options may only be granted to employees of the Company and its subsidiaries. The Stock Plan also provides that on the day following each annual meeting of the Company’s stockholders each non-employee director will receive an automatic grant of options to purchase 4,000 shares of the Company’s common stock. In addition, any person who is appointed or elected as a non-employee director at any other time will receive an automatic grant of options to purchase 4,000 shares of the Company’s common stock on the date of such appointment or election. Each grant will have an exercise price equal to fair market value on the date of grant and will vest in full on the first anniversary of the grant date.

In February 2004, 22,200 options were granted to employees.

Activity related to options under the option plans for the fiscal year ended March 31, 2004 was:
