PART I

Item 1. Business

The Company

Calypte Biomedical Corporation (“Calypte” or the “Company”) believes that it is a leader in the development of a urine–based screening test for the detection of antibodies to the Human Immunodeficiency Virus, Type–1 (“HIV–1”), the putative cause of Acquired Immunodeficiency Syndrome (“AIDS”). The Company has integrated several proprietary technologies to develop a test (the “Calypte urine-based HIV-1 screening test”) which, in clinical trials, detected the presence of HIV antibodies in urine with 99.7% sensitivity in subjects previously identified as HIV–1 infected through blood–based (serum/plasma) screening tests. In subjects at low risk for HIV, the specificity of the Calypte urine-based HIV-1 screening test used with a companion urine-based Western Blot supplemental test was 100%. Specificity and sensitivity in other populations, including those at high risk and those with other medical conditions, has been shown to be reduced in other clinical trials when compared to testing with blood specimens. Calypte believes that its proprietary urine–based HIV-1 screening test offers significant advantages compared with existing blood–based tests, including ease–of–use, lower costs, and significantly reduced risk of infection from collecting and handling specimens. In contrast to blood, urine collection is non–invasive and painless, and urine is the most commonly collected body fluid. Consequently, the Company expects that most businesses and organizations that conduct HIV-1 testing will find the cost of collecting, handling, testing and disposing of urine specimens to be significantly less than that of blood specimens. In addition, independent studies report that the likelihood of finding infectious HIV virus in urine is extremely low, greatly reducing the risk and cost of accidental exposure to health care workers, laboratory personnel, and patients being tested.

The Company was incorporated in California in 1989 and reincorporated in Delaware in 1996 at the time of its initial public offering. In August 1996, the Company received a product license and an establishment license from the Food & Drug Administration (“FDA”) to manufacture and sell, in interstate and foreign commerce, the Company’s urine–based HIV–1 screening test for use in professional laboratory settings. In May 1998, Cambridge Biotech Corporation (“Cambridge Biotech”), the manufacturer of the companion urine-based HIV-1 Western Blot supplemental test, also received the product and establishment licenses from the FDA with respect to its urine-based Western Blot test. Calypte uses the Cambridge Biotech Western Blot urine-based test as a supplemental test on samples that have been repeatedly reactive in Calypte’s urine-based HIV–1 antibody screening test. As a result of the regulatory approvals, Calypte’s screening test, when used with the Western Blot urine-based supplemental test for HIV-1, became, and remains, the only complete FDA–approved urine–based HIV testing method. Alternatively, Cambridge Biotech’s serum-based Western Blot HIV-1 test can also be used as a supplemental confirmatory test for subjects whose urine samples have been reactive in Calypte’s urine-based screening test.

In December 1998, Calypte acquired from Cambridge Biotech certain assets relating to Cambridge Biotech’s Western Blot product line for certain infectious diseases. The acquisition included Cambridge Biotech’s urine–based and serum–based HIV–1 Western Blot products, as well as a supplemental test for Lyme Disease and Human T–Lymphotropic Virus (HTLV). The Company has discontinued both the Lyme Disease and HTLV tests.

In November 1999, Calypte received FDA approval of a “Day Assay” format for its “Cambridge Biotech” HIV–1 serum Western Blot assay. The FDA approval permits use of the supplemental serum-based Western Blot test in either a “Day Assay” (five hour) or overnight format, and allows more rapid test results for customers and their patients who need the results of their HIV tests as rapidly as possible.

The Company intends to develop additional or improved urine and blood–based tests for other infectious and viral diseases. The Company will also continue to explore the potential for an over–the–counter in–home urine collection kit.

Calypte markets its urine–based HIV–1 screening test and its Cambridge Biotech confirmatory tests through direct sales personnel and distributors depending upon the market segment and the location of the market. There can be no assurance that the Company’s planned products will receive or maintain FDA clearance or approval and become commercially available or that the Company’s FDA-approved products will maintain FDA clearance or approval and remain commercially available.

Background

HIV is the putative cause of AIDS, which is a leading cause of death for persons ages 25 to 44 in the U.S. Those infected with HIV generally do not show symptoms of AIDS until several years after HIV infection, if at all. Because most persons infected with HIV are asymptomatic for AIDS and are unaware of their HIV status, such persons do not avail themselves of medical treatment and may unknowingly expose others to the risk of infection. Prior exposure to HIV can be detected in laboratory tests even though the individual infected with HIV is asymptomatic.

According to the December 2001 AIDS Epidemic Update published jointly by the Joint United Nations Programme on HIV/AIDS and the World Health Organization, at the end of 2001 an estimated 40 million people globally were living with HIV; over 21 million people had already died from the disease, and an estimated 5 million people were newly infected with HIV during 2001. The Update reported that about 3 million people died of AIDS during 2001. The publication also noted that about one-third of those currently living with HIV/AIDS are aged 15-24 years and that most of them do not know they carry the virus. HIV is spread by a transfer of bodily fluids, primarily through sexual contact, blood transfusions, sharing intravenous needles, accidental needle sticks or transmission from infected mothers to newborns.

The discovery in 1984 of circulating HIV antibodies in the blood led to the development and widespread use of HIV blood screening tests. Testing by blood banks of blood used in transfusions soon followed in an effort to maintain and protect the integrity of the blood supply. Most HIV antibody screening tests are enzyme immunoassays (“EIAs”). These tests operate on the principle that antibodies will react with a known antigen. This reaction is detected by using enzymes as indicators. Outside of blood bank screening, physicians, the life insurance industry, the military, the criminal justice system, and the Immigration and Naturalization Service generate the largest domestic demand for HIV testing.

To minimize the risk of incorrectly reporting that an individual is infected with HIV (a false positive result), most countries require a strict testing protocol. The protocol is to first test a sample for the presence of HIV. Any sample found to be reactive in the initial screen is then retested in duplicate. If either of the retests are reactive, the same sample is tested again using a more precise and expensive supplemental test. The presence of HIV antibodies, based on the results of the supplemental test, is considered diagnostic for HIV infection.

The human immune system typically requires a number of weeks or months to begin producing antibodies following exposure to HIV. There is no consensus in the scientific community as to whether antibodies can first be detected in blood, urine or oral fluid.

HIV blood testing can be expensive and poses risk of infection to health care personnel. The typical HIV screening test requires a trained health care worker or phlebotomist to draw and centrifuge a blood sample, which is then tested for the presence of HIV antibodies. Blood is typically drawn at physician offices, clinics, hospitals or blood draw stations, where trained personnel are available, and then sent to a laboratory for HIV testing. Blood samples and related blood-sampling equipment require careful handling if healthcare personnel are to avoid accidental exposure to blood-borne pathogens, including HIV. In addition, the use of blood-based tests has become increasingly costly because of the costs of disposing of potentially infected specimens, syringes, needles and transfer tubes. The overall cost of blood-based testing has precluded large public health screening programs, particularly in less developed countries, many of which have significantly higher rates of HIV infection than that of the U.S. Even in the United States, certain populations are not routinely screened due to the high cost of blood-based testing.

In December 1994, the FDA approved the first non-invasive method for HIV-1 testing, an oral fluid-based screening test and collection device. Collection of oral fluid is technique dependent, and detailed instructions on the proper use of the oral fluid collection device need to be carefully followed. In addition, oral fluid is not commonly collected and is rarely tested for other diagnostic purposes. In June 1996, one manufacturer received approval from the FDA for a Western Blot oral-fluid supplemental test.

HIV screening can also be performed by using a dried blood spot (“DBS”) specimen. DBS sampling, which was developed in the late 1980’s, is a variant of blood sampling initially designed for the testing of newborns. The DBS sampling method involves sticking a baby’s heel or an adult’s finger with a sharp lancet and collecting five or six drops of blood onto filter paper. The laboratory punches the dried blood spots out of the filter paper, and the non-cellular components of the blood spot are eluted back in liquid form by soaking the punches in diluent. The resulting fluid is then assayed by one of several traditional serum/plasma enzyme immunoassays licensed for use with DBS.

The DBS method, which is comparable in cost to traditional serum tests, is susceptible to problems in sample variability, the adequacy of volume for testing, pain on blood sampling and invasiveness.

The Calypte Urine-Based HIV-1 Screening and Supplemental Tests

Calypte’s proprietary urine-based HIV-1 screening test is non-invasive, easy to use, reliable and avoids many of the costs and risks associated with blood-based testing. The Company’s screening test, when used with the Western Blot supplemental test for urine provides the only complete urine-based HIV testing method. Laboratories using the Company’s method can complete the entire testing profile for HIV-1 antibody using a single urine specimen. The Company believes that the benefits of its testing method will enable it to penetrate existing markets and expand into new markets that are not served currently by the more expensive blood and oral fluid-based HIV test systems. Key benefits of the Company’s test include:

Ease of Use/Non-Invasive Collection. Urine is the most commonly collected bodily fluid for laboratory testing as it is already being collected for testing purposes other than the detection of the HIV-1 antibody. Collection of the urine can take place any time of day, and the test does not require a 24-hour voided specimen or a midstream, clean-catch sample. Because it requires no special preservatives or containers, it is also easier to collect, handle, and discard than blood. Furthermore, the Company’s test is in standard EIA format and is designed to be used with standard laboratory equipment. Blood sampling is invasive and, for many patients, stressful and painful. The ability to screen non-invasively for HIV in all types of patients, including injection drug users and newborns, will enhance patient comfort and may significantly increase the voluntary testing rates in patients who might otherwise decline testing. Moreover, unlike urine collection, obtaining an oral fluid specimen is highly technique-dependent, requiring specific placement of a collection device in the mouth, rubbing the collection device along the gum line, and holding it in place for no less than two and no more than five minutes. Unlike oral fluid, the collection of urine does not require specially trained personnel, nor is its collection restricted to patients of certain ages.

Lower Overall Cost. The Company’s urine-based screening test may lower significantly the overall cost of testing for HIV infection because the cost of collecting, transporting, testing and disposing of urine specimens can be significantly less than that of blood specimens, and less than the cost of an oral fluid screening test. Additional cost savings may accrue as a function of reduced needlestick incidents and their associated counseling, testing and lost productivity. With respect to oral fluid screening tests, the Company believes that each oral fluid collection device costs between $3.00 to $5.00, while a urine collection cup costs between $0.05 and $0.50. Moreover, since urine is often already being collected for other testing purposes, the incremental cost of collecting urine samples is likely to be lower than collecting oral fluids. Nonetheless, the total cost of deploying urine, blood or oral-based HIV screening tests or a combination thereof will vary according to the testing purpose and protocol and whether other diagnostic tests are performed simultaneously. The ancillary costs (such as collection method, accidental exposure to HIV and sample disposal) associated with blood testing are more expensive than urine testing.

Safety. Independent studies have concluded that the likelihood of finding infectious HIV virus in urine is extremely low. There have been no reported cases of transmission of HIV virus through contact with urine of HIV-infected patients. Accordingly, the risk of HIV infection to health care and laboratory workers accidentally exposed to urine samples is negligible. Since no needles are used in the Calypte urine sampling process, the test eliminates this route of accidental infection. In developing countries, where the supply of sterile needles and syringes cannot be guaranteed, the safety benefits of using urine sampling extend to patients as well as to health care workers.

Reliability. The Company has performed clinical studies demonstrating the effectiveness of using urine as a reliable and clinically valid sample for HIV testing. In Company-funded clinical trials conducted by or on behalf of the Company, for the HIV-1 urine EIA and the urine Western Blot supplemental test, more than 11,000 paired blood and urine specimens were tested. Two measures of the reliability of our urine-based HIV test were employed-specificity and sensitivity. Specificity is the ability of an assay or method to identify all non-HIV infected individuals correctly. Sensitivity is the ability of the assay or method to detect truly HIV-infected individuals. In recent studies where specificity was assessed by testing specimens from a combined subset of low risk subjects, the resulting specificity was 100% for the screening test in conjunction with the supplemental test. Specificity and sensitivity in other populations, including those at high risk and those with other medical conditions, is reduced compared to testing with blood specimens. Sensitivity (correlation to blood tests) of the urine testing method was estimated by testing samples from a subset of individuals known to be infected with HIV-1, including those with a clinical diagnosis of AIDS. The sensitivity in that subset was measured at 99.7%.

In spite of the benefits of the Company’s urine-based screening and supplemental tests, such tests represent a new method of determining the presence of HIV antibodies. Blood-based and oral fluid based tests, which constitute competitive products, have the advantage of already being commercially marketed and have gained acceptance from the medical community. Furthermore, both blood-based and oral fluid based tests have been shown to be reliable media for detection of HIV. There can be no assurance that the Company’s urine-based screening test will gain any significant degree of market acceptance among physicians, patients or health care payors, even if the necessary reimbursement approvals are obtained.

Calypte’s HIV-1 antibody test is a much-needed alternative for people who fail to get tested for HIV because they are afraid of needles. It is critical for all people at potential risk for HIV infection to learn their status because early detection and treatment have been shown to prevent debilitating opportunistic infections and to extend life. Studies have shown that between 21% to 50% of people would prefer a urine test rather than a blood test, and up to 80% of these individuals cited fear of needles as the reason for preferring a urine test. Between 800,000 to 900,000 Americans are living with HIV, and an estimated one in three do not know they are infected.

Test Methodology. The Company’s urine-based screening test uses an industry-standard 96 well microtiter plate to detect antibodies to HIV-1 in urine. The HIV-1 antibodies, when present in urine, bind to Calypte’s proprietary antigen coated on prepared microtiter plates. A subsequent enzymatic reaction produces a color change revealing the presence of HIV-1 antibodies.

The screening test requires only 200 microliters of urine (approximately four drops) and can be performed using standard laboratory equipment. Samples can be shipped and stored at 15 to 30 degrees centigrade for up to 55 days, or for up to 1 year at 2 to 8 degrees centigrade, before testing. The laboratory protocol for testing urine is nearly identical to that of blood, and therefore requires few, if any, modifications to existing laboratory protocols.

The Cambridge Biotech HIV-1 Western Blot is an in vitro qualitative assay for the detection and identification of antibodies to HIV-1. This more specific assay is used as a supplemental test with specimens (serum, plasma or urine) that tested repeatedly reactive using an EIA screening procedure.

The Cambridge Biotech HIV-1 Western Blot is manufactured from HIV-1 propagated in an H9/HTLV-IIIB T-Lymphocyte cell line. The virus is inactivated and specific HIV-1 proteins are bound to a nitrocellulose strip.

Each strip contains all of the proteins and glycoproteins of HIV arranged in bands across the strip in order of molecular weight. If HIV-1 antibodies are present in the specimen, they will bind to the viral antigens present on the nitrocellulose strip. The position of bands on the nitrocellulose strips allows this antibody reactivity to be associated with specific viral antigens.

The Company’s Cambridge Biotech urine-based supplemental test uses the same commercially available Western Blot kit components as provided for the blood based Cambridge Biotech supplemental test. The test procedure is virtually identical as well, except that the urine-based supplemental test requires 1.0 milliliter of urine added directly to the standard kit diluent and the urine-based test requires additional times of incubation for the two detection steps. The same laboratory equipment is used for both the blood and urine supplemental tests.

Additionally, the Cambridge Biotech urine-based Western Blot kit is differentiated for urine-based testing by virtue of the urine Western Blot controls included with the Western Blot blood kit and a different blot interpretation criterion. For urine, blots showing the presence of a single band, gp160, equal to or greater intensity than the low positive urine Western Blot control are interpreted as a positive HIV-1 result. Urine blots have a lower indeterminate rate than blood, allowing more definitive negative or positive results.

In December 1998, Calypte acquired from Cambridge Biotech certain assets relating to the Western Blot product line for HIV-1 and certain other infectious diseases. The acquisition included Cambridge Biotech’s urine-based and serum-based HIV-1 Western Blot products, as well as a supplemental test for Lyme Disease and Human T-Lymphotropic Virus (HTLV). Since the acquisition, the Company has made significant investments in the Rockville facility to enhance manufacturing capability and establish quality system compliance as a core competency. It has also discontinued production of the tests for Lyme Disease and HTLV.

The Cambridge Biotech Serum-Based HIV-1 Supplemental Test

As the first of the four supplemental blot tests for blood HIV-1 antibodies to be FDA-licensed, the serum-based Cambridge Biotech HIV-1 Western Blot kit has been in commercial distribution for more than 9 years. Since the FDA’s November 1999 approval of a “Day Assay” format, the supplemental test is available in both five-hour and an overnight format. Calypte sells The Cambridge Biotech serum-based Western Blot test for HIV-1 as a supplemental test to HIV-1 screening tests produced by other manufacturers.

The Sentinel Testing Service

In May 2000, the Company launched its participation in a new national urine-based testing service for HIV-1 antibody, chlamydia, and gonorrhea. The service, called Sentinel^™ (“Sentinel”), was initially a collaboration between the Company, Wampole Laboratories, a division of Carter-Wallace, Inc. and Clinical Reference Laboratory. In August 2001, modifications were made to the service to strengthen the product offering. Sentinel is now a collaboration between the Company and Center for Disease Detection, a reference laboratory licensed for diagnostic testing throughout the United States. The service offers a painless, non-invasive, urine-based sampling method designed to identify HIV-1 antibody, and chlamydia and gonorrhea sexually transmitted diseases (“STDs”). The Sentinel service provides a four-day response and for the testing of all three STDs on urine, Sentinel is priced below the Medicaid reimbursement level in most states. The service is targeted primarily to community-based and AIDS service organizations. The Company manufactures the HIV-1 antibody tests used in the Sentinel service. Sentinel screening sales were not significant in either 2001 or 2000. The Company is focusing on expanding the U.S. Diagnostic and Sentinel business during 2002.

HIV Viral Lysate Stock

HIV viral lysate is a component that Calypte uses in the manufacture of its Cambridge Biotech Western Blot supplemental test products. Although Calypte does not actively market HIV viral lysate as a distinct product line,

it does make sporadic sales of its HIV viral lysate stock from time to time. During 2001, viral lysate sales accounted for approximately 20% of Calypte’s revenues and such sales made the primary customer for HIV viral lysate Calypte’s second largest single customer. Calypte expects that HIV viral lysate sales will decrease during 2002 and the Company does not believe that such sales represent a long-term market opportunity. However, it does expect HIV viral lysate sales to continue sporadically at unpredictable levels in the short-term future.

Products Under Development

The Company’s research and development efforts are directed toward process improvements and the development of select high-priority new diagnostic products. Priority is determined on the basis of feasibility, probable cost to develop, regulatory complexity, market size and competition.

Rapid Test. The Company has investigated the feasibility of a rapid test in response to the reports by the Center for Disease Control and Prevention (CDC) on the value of immediate HIV antibody test results and development is in an early stage. The high number of individuals who do not return for test results and counseling constitutes a threat to the public health. In addition, in emergency rooms, delivery rooms and other settings, there is an urgent need to know the HIV status of the patient. Since azidothymidine (“AZT”) treatment of pregnant mothers, even at delivery and for the newborn, has been shown to result in a substantial decrease in HIV transmission, there appears to be a new market for the reliable rapid test format. At this time, the Company believes it would be premature to issue predictions as to the product’s reliability and cost or the likelihood of success and timing of product development.

Other Diagnostics. The Company intends to develop additional or improved urine tests for other infectious and viral diseases. The Company is focusing development on products which are complementary to its existing product line and market opportunities. These may include development of urine-based tests for assessment of liver and cardiac risk for use in the insurance underwriting industry and tests for additional sexually transmitted diseases.

OTC. The Company will continue to explore the potential for an over-the-counter in-home urine collection kit for use in HIV diagnosis. However, due to regulatory approval uncertainties and cost concerns, this is not a near-term priority development for the Company.

Research and Development Spending. The Company continues to invest the funds in research and development that it believes are necessary and appropriate to ensure that its HIV-1 urine-based screening test meets customer requirements and to explore the potential for other new urine-based diagnostic products. The Company spent $1.5 million, $2.3 million and $4.1 million on product research and development in 2001, 2000 and 1999, respectively. Future spending will be devoted to product and process improvements for its existing products, as well as to new product development. Spending for 2002 is expected to approximate that of 2001, but is substantially dependent on the success of the Company’s financing activities during the year.

Sales, Marketing and Distribution

The Company’s marketing strategy is to use distributors and focused direct selling to penetrate certain targeted domestic markets. The Company maintains a small direct sales force to sell the Company’s HIV-1 screening test and potential future products to community-based organizations, public health laboratories, reference laboratories and the life insurance market. International and other U.S. markets have been addressed utilizing diagnostic product distributors. In late summer of 1998, the Company began selling its urine-based HIV-1 test with the Western Blot supplemental test in the U.S. To date, the Company has received approval for the sale of its product outside of the U.S. in Indonesia, the Republic of South Africa, the People’s Republic of China, and Malaysia. Several international approvals are pending, and the Company is working collaboratively with its distributors to obtain regulatory approval to market and promote the products in their local markets.

The Company anticipates that a portion of its revenues for the next several years will be derived from international distributor sales. International sales and operations involve a number of inherent risks and may be limited or disrupted by the imposition of government controls, export license requirements, political instability, trade restrictions, changes in tariffs, difficulties in managing international operations and fluctuations in foreign currency exchange rates. Distributors of medical products in developing countries where the need for cost-effective HIV diagnostic tests may be the most acute often find it difficult to establish and maintain the necessary transportation, storage, and credit facilities. Certain of the Company’s distributors have limited international marketing experience, and there can be no assurance that the Company’s distributors will be able to successfully market the Company’s products in any international market.

The following table summarizes the markets and geographic regions covered by the Company and its distributors for its HIV-1 tests. It includes distribution arrangements that were in effect during 2001 and/or will be come effective in the first half of 2002. International distributors generally have exclusive rights within their geographical territory.

Centrum Promotora Internacional	Mexico	All

The agreements generally have terms of from one to three years. Continuing exclusivity and agreement renewal or extension is typically dependent upon specific minimum purchases following successful local regulatory approval of the product.

The Company’s products represent an alternative to the blood-based method of determining the presence of HIV antibodies and there can be no assurance that these products will gain any significant degree of market acceptance among community-based organizations, physicians, patients or health care payors, even if necessary international and U.S. regulatory and reimbursement approvals are obtained. The Company believes that recommendations and endorsements by community based organizations and the medical community will be essential for market acceptance of the products, and there can be no assurance that any such recommendations or endorsements will be obtained. The Company has little experience marketing and selling its products either directly or through its distributors. The Company’s marketing strategy relies upon its direct sales force and its alliances with third-party distributors for the success of its products. There can be no assurance that the Company’s direct sales force will be effective, that its distributors will successfully market the Company’s products or that, if such relationships are terminated, the Company will be able to establish relationships with other distributors on satisfactory terms, if at all. Any disruption in the Company’s distribution, sales or marketing network, or failure of the Company’s products to achieve market acceptance, could have a material adverse effect on the Company’s business, financial condition and results of operations.

In 2001, the Company’s revenue from product sales totaled $6.8 million. Approximately 95% of Calypte’s 2001 product sales revenues arose from sales to customers in the United States. The Company had a $68,000 backlog of unfilled orders at December 31, 2001.

The Company is currently negotiating with other potential distributors of its HIV product line in various countries, including Taiwan, India, and Russia and is investigating possibilities for expanding its distribution in China.

Manufacturing

The manufacture of the Company’s urine-based HIV test involves antigen production, plate processing and preparation of certain washes and other reagents. All processes are carried out under FDA Good Manufacturing Practices (“GMP”) regulations. Antigen production involves cell culture, antigen expression and purification. Following purification, the antigen is tested extensively and optimized for plate coating. The coating of standard 96 well microtiter plates with antigen is completed using industry standard plate coating equipment. Following binding of the antigen to the plates, the plates are blocked and stabilized to prevent nonspecific binding of the antigen. The plates are then dried and packaged in foil pouches. The washes and reagents are produced using standard solution preparation techniques.

In January 2001, Calypte’s Alameda, California manufacturing facility was granted pre-market approval (“PMA”) by the U.S. Food and Drug Administration (FDA) following a zero-observation pre-approval inspection. The capacity of the Alameda facility is approximately 20 million tests per year and is expected to significantly increase the Company’s production and distribution capabilities. The Company closed its original Berkeley site in February 2001. The Company’s other manufacturing site, located in Rockville, Maryland, remains in operation.

In December 1998, the Company acquired certain assets of Cambridge Biotech Corporation, including the manufacturing facilities for its HIV-1 product line in Rockville, Maryland. The Rockville facility also has an approved Biologics License (“BL”) from the FDA for the urine and blood-based Western Blots.

Between April 3 and April 11, 2001, the FDA conducted an inspection of the Rockville facility that resulted in a few minor observations requiring corrective actions or response from the Company. The Company responded in writing to the FDA on April 23, 2001 addressing these observations.

Although the FDA indicates it is currently satisfied with the Company’s responses, if the FDA subsequently determines that it is not satisfied with the Company’s responses and corrective actions regarding these matters at its Rockville facility, or if the FDA observes new conditions requiring corrective actions which remain unresolved following inspections at either the Alameda or Rockville facilities, the FDA could take regulatory actions against the Company, including license suspension, revocation, and/or denial, seizure of products and/or injunction, and/or civil penalties or criminal sanctions. Any such FDA action would likely have a material adverse effect upon the Company’s ability to conduct operations.

Calypte purchases raw materials and uses components in the manufacture of its products that it obtains from various suppliers. The Company uses some single-source components, and any delay or interruption in supply of these components could significantly impair the Company’s ability to manufacture products in sufficient quantities to meet established and increasing commercial demand because establishment of additional or replacement suppliers for single-source components cannot be accomplished quickly.

Calypte also has limited experience in the commercial-scale manufacture of its products. The Company currently manufactures its products for sale, for submission to FDA for ongoing compliance, for clinical trials, and for building its inventory. Calypte may encounter difficulties in scaling-up production of its products, including problems involving production yields, quality control and assurance, raw material supply and shortages

of qualified personnel. Due to Calypte’s limited manufacturing experience, its estimates with regard to these and other operational requirements may be incomplete or inaccurate and unanticipated events and circumstances are likely to occur. Difficulties encountered by the Company in manufacturing scale-up to meet demand could have a material adverse effect on its business, financial condition and results of operations.

Due to the nature of its manufacturing processes, the Company is subject to stringent federal, state and local laws, rules, regulations and policies governing the use, generation, manufacture, storage, air emission, discharge, handling and disposal of certain materials and wastes. There can be no assurance that the Company will not be required to incur significant costs to comply with land use and environmental regulations as manufacturing is scaled-up to commercial levels, nor that the operations, business or financial condition of the Company will not be materially and adversely affected by current or future environmental laws, rules, regulations and policies. There can be no assurance that the Company will be able to obtain and maintain all required permits in connection with the operation of its manufacturing facilities. As the Company manufactures its products on a larger commercial scale, it is a significant user and disposer of water. The disposal of water used in the Company’s manufacturing processes must comply with applicable federal, state and local environmental protection laws, and compliance with these laws may be costly and difficult.

The manufacturing facility in Maryland is a specialized facility incorporating Biosafety Level 3 controls for the manipulation of potentially infectious biological agents (HIV viruses) as well as the use of hazardous chemical materials. As such, this facility and the products manufactured there are subject to rigorous Federal, State and local regulatory controls including registration, licensing and specific material use permits. Should it become necessary to move the Maryland operations to a different location in the future, significant costs, time and resources would likely be required to validate such a transfer and obtain the required regulatory clearances.

Technology

The Company’s HIV-1 urine-based test is based on the discovery by scientists at the New York University Medical Center in 1988 that antibodies to HIV-1 could be found in urine. Prior to this discovery, it was commonly held that antibodies to systemic infections could not pass through the kidneys, and thus, could not be found in the urine of infected individuals. The researchers showed that antibodies to HIV-1 envelope antigens were present in all urine samples from HIV-1 seropositive subjects. Building on this discovery, the Company developed an HIV-1 urine enzyme immunoassay (“EIA”) to detect antibodies to HIV-1 in urine. There are two proprietary features of the Company’s HIV-1 urine-based EIA that result in a format sensitive enough to detect the low levels of HIV antibodies in urine: the antigen target and the sample buffer in the assay.

Recognizing the prominence of envelope antibodies in urine, the antigen target in the assay is a full length, recombinant glycosylated HIV-1 envelope protein, rgp160. Although this antigen is a recombinant glycoprotein, it is identical to the viral envelope protein gp160 in amino acid sequence and in the presence of carbohydrate at glycosylation sites. This kind of antigen target can efficiently capture the full range of HIV-1 envelope specific antibodies produced in the human polyclonal response to the virus. The microwell assay format permits the high availability of epitopes of the recombinant envelope glycoprotein for antibody binding. This availability of epitopes results in the sensitivity verified in clinical trials.

The Company has non-exclusive rights to the proprietary process used to express the recombinant HIV-1 envelope glycoprotein from Texas A&M University. This proprietary process for manufacture of rgp160 begins with the baculovirus expression vector system established in an insect cell culture. The consistent and high levels of rgp160 expression in baculovirus infected insect cell culture is a critical step in the overall manufacturing of rgp160. The Company improved and upgraded the Repligen Corporation (“Repligen”) process with a proprietary process which uses a system in which the HIV-1 envelope protein is produced in the insect cell membrane rather than typical tissue culture systems where the protein is secreted into insect cell culture media. Rgp160 is an insoluble protein and requires detergent based extraction and purification procedures which are proprietary.

The Company developed and has obtained a U.S. patent claiming a sample buffer formulation, which is used in the HIV-1 urine test. This sample buffer acts as a diluent for urine in the assay procedure and significantly increases test specificity by reducing non-specific binding of immunoglobulins (non-specific antibodies) and other substances in urine that would decrease specificity and sensitivity of HIV-1 antibody binding. Sample buffer is manufactured in the Company’s Alameda, California facility.

The Company’s products incorporate established immunoassay technology based on antibody-antigen reactions. Antibodies are immune system proteins produced as a result of an organism’s immune response to substances (antigens) foreign to the body and specifically bind to antigens and signal the immune system to assist in eliminating them. Immunoassays are used for diagnostic applications where the presence or absence of a specific analyte is being evaluated and allow the detection of some analytes at levels as low as one part per billion. Antigens include viruses, bacteria, parasites, chemical toxins and other foreign substances and hormones.

The HIV-1 urine assay format includes a standard 96 well microtiter plate which is compatible with standard laboratory instrumentation. The microwell plates are coated with proprietary recombinant HIV-1 envelope protein antigen. Patient urine and the unique specimen diluent are introduced to the microwell simultaneously. If HIV-1 antibodies are present, they bind to the antigen coated well and remain during the subsequent wash steps. An enzyme labeled conjugate is added to the well. This conjugate binds specifically to human antibody which remains from the previous step. Following another wash, substrate reagent is added and color development occurs due to the presence of the enzyme conjugate in the well. This color is measured spectrophotometrically on a standard laboratory microwell plate reader. The presence of HIV antibody in the specimen is indicated by the development of color in the microwell, and the intensity of the color is proportional to the amount of antibody.

The Company’s HIV-1 urine-based supplemental test uses the Cambridge Biotech HIV-1 Western Blot kit with a procedure developed by Calypte for testing urine specimens. The Cambridge Biotech HIV-1 Western Blot kit is based on the combination of electrophoretic separation of complex mixtures of proteins with the highly sensitive immunoblotting technique. This method has been highly useful in characterizing the antigenic profile of HIV-1 and describing the immune response to HIV-1 in the serum/plasma of exposed or infected persons.

There are now two products available for the supplemental Cambridge Biotech HIV-1 Western Blot kit. One is used for testing blood and the other for testing urine specimens. The manufacture of these kits involves the production of an inactivated, partially purified HIV-1 lysate from HIV-1 propagated in an H9/HTLV-III_b T-lymphcyte cell line. HIV-1 proteins are separated by molecular size using gel electrophoresis of the lysate in the presence of detergent (sodium dodecylsulfate). The separated HIV-1 proteins are electrotransferred from gel to a nitrocellulose membrane that is washed, blocked to minimize non-specific immunoglobulin binding and packaged. These kits provide controls and components which enable the detection and visualization of HIV-1 antibodies present in the specimen incubated with individual nitrocellulose membrane strips. Bands corresponding to specific location of HIV-1 proteins are used to interpret a positive, negative or indeterminate result.

Patents, Proprietary Rights and Licenses

The Company believes that its future success will depend in large part on its ability to protect its patents and proprietary rights. Accordingly, the Company’s ability to compete effectively will depend in part on its ability to develop and maintain proprietary aspects of its technology. The Company has two U.S. patents, one pending U.S. patent application, six foreign patents, and eight pending foreign patent applications. In addition, the Company currently has the right to utilize certain patents and proprietary rights under licensing agreements with New York University (“NYU”), Cambridge Biotech Corporation, Repligen, and Texas A&M University System. These license arrangements secure intellectual property rights for the manufacture and sale of the Company’s products.

The Company has licensed from NYU, on an exclusive basis, a U.S. patent for the detection of antibodies to HIV in urine. The rights under the license extend until the expiration of the U.S. patent in 2009. The Company

has the right to make, use, sell and sublicense products utilizing the technology described in the patent and is obligated to make certain fixed and royalty payments to NYU to maintain exclusivity of the license. In connection with the NYU license, the Company also funded research at NYU through 1999. The Company has exclusive worldwide license to NYU inventions that arise from the research funded by the Company.

The Company has sublicensed from Cambridge Biotech Corporation proprietary technology related to the HIV envelope glycoprotein. The sublicense grants to the Company a non-exclusive worldwide sublicense to make, have made, use and sell products that relate to the licensed technology. The Company is required to pay Cambridge Biotech Corporation royalties on products incorporating the licensed technology. The license extends until the expiration of the licensed patents in 2005, although the Company can terminate the agreement at any time upon 30 day’s written notice.

The Company has been granted a non-exclusive license from Texas A&M University to make, have made, use and sell products based on its proprietary recombinant expression systems. The Company is required to pay certain fixed and royalty payments to Texas A&M University on net sales varying with the content of Texas A&M’s technology in the Company’s products.

The Company licensed from Repligen HIV-1 gp160 recombinant virus seed stock. The Company has been granted (i) an exclusive license to make, have made, use and sell products incorporating this material for diagnostic purposes, and (ii) non-exclusive license to make, have made, use and sell the gp160 seed stock for research purposes. For seven years beginning on the date the Company first realizes net sales from products incorporating gp160, the Company must pay to Repligen certain royalties on net sales derived from such products and certain royalties on net sublicensing revenue derived from sales of products incorporating gp160.

In conjunction with Calypte’s acquisition of certain assets of Cambridge Biotech related to Cambridge Biotech’s Western Blot supplemental tests for HIV-1, Calypte assumed certain patent and proprietary rights material to the manufacture and sale of the serum-based Western Blot test under a licensing agreement with the National Institutes of Health (“NIH”).

In the event that the Company does not develop alternate sources of revenues, its obligation to make minimum royalty payments under licenses requiring such payments could have a material adverse impact on the Company’s results of operations. Failure to make required minimum royalty payments may also result in the loss by the Company of exclusivity under, or termination of, such certain licenses. In February 2002, the Company reached agreements with NYU with respect to past due royalty payments and is currently in discussions with Biomerieux and NIH regarding past due payments under their respective licenses.

The HIV testing industry has been characterized by extensive litigation regarding patents and other intellectual property rights. Litigation or interference proceedings could result in significant diversion of efforts by the Company’s management and technical personnel. There are a number of filed and issued patents involved with the detection of HIV antibodies. One such patent is currently owned by Chiron Corporation. While the Company, based on the opinion of its patent counsel, believes that its urine-based HIV-1 screening test does not infringe the Chiron patent, there can be no assurances that Chiron will not assert such claims against the Company. In addition, Calypte has received correspondence from NIH alleging that the Company’s urine-based test products are also subject to the patent under which the Company licenses its serum-based Western Blot supplemental test and requesting the payment of additional license fees on both past and future product shipments. Calypte has informed NIH that it does not agree with NIH’s analysis of the patent in question and the parties are continuing discussion. Patent litigation can be costly and protracted. The expense of litigating a claim against the Company for patent infringement could have a material adverse effect on the Company’s business, financial condition and results of operations. In the event that the Company was found to be infringing a validly issued patent, and the Company could not obtain a license to such patent on reasonable terms, the Company could be forced to pay damages, obtain a license to such patent at a significantly higher rate or, possibly, remove its urine-based HIV-1 screening test from the market. Such an event would have a material adverse effect on the Company’s business, financial condition and results of operations.

In addition, there can be no assurance that competitors, many of which have substantial resources and have made substantial investments in competing technologies, do not have, or will not seek to apply for and obtain, patents that will prevent, limit or interfere with the Company’s ability to make, use or sell its products either in the U.S. or in international markets. There can be no assurance that the Company will not be required to obtain additional cross licenses in the future or that the Company will not in the future become subject to patent infringement claims and litigation or interference proceedings declared by the U.S. Patent and Trademark Office (“USPTO”) to determine the priority of inventions. The defense and prosecution of intellectual property suits, USPTO interference proceedings and related legal and administrative proceedings are both costly and time consuming. Litigation may be necessary to enforce patents issued to or licensed by the Company, to protect trade secrets or know-how owned by the Company or to determine the enforceability, scope and validity of the proprietary rights of others.

Although patent and intellectual property disputes in the medical diagnostic area have often been settled through licensing or similar arrangements, costs associated with such arrangements may be substantial and could include ongoing royalties. Furthermore, there can be no assurance that necessary licenses would be available to the Company on satisfactory terms if at all. Adverse determinations in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent the Company from manufacturing and selling its products, which would have a material adverse effect on the Company’s business, financial condition and results of operations. There can be no assurance that the Company will be able to maintain exclusivity under or maintain its current license agreements. Termination of any of these licenses could have a material adverse effect on the Company’s business, financial condition and results of operations.

The Company relies on trade secrets and proprietary know-how, which it seeks to protect, in part, through appropriate confidentiality and proprietary information agreements. These agreements generally provide that all confidential information developed or made known to the individual by the Company during the course of the individual’s relationship with the Company is to be kept confidential and not disclosed to third parties, except in specific circumstances. The agreements generally provide that all inventions conceived by the individual in the course of rendering services to the Company shall be the exclusive property of the Company. However, certain of the Company’s agreements with consultants, who typically are employed on a full-time basis by academic institutions or hospitals, do not contain assignment of invention provisions. There can be no assurance that proprietary information or confidentiality agreements with employees, consultants and others will not be breached, that the Company would have adequate remedies for any breach, or that the Company’s trade secrets will not otherwise become known to or independently developed by competitors.

Government Regulation

Overview

The Company’s products are subject to extensive regulation by the FDA and, to varying degrees, by state and foreign regulatory agencies. The Company’s products are regulated by the FDA under the Federal Food, Drug, and Cosmetic Act (the “Act”), as amended by the Medical Device Amendments of 1976, the Safe Medical Devices Act of 1990, and the FDA Modernization Act of 1997 among other laws. Under the Act, the FDA regulates the preclinical and clinical testing, manufacturing, labeling, distribution, sale and promotion of medical devices in the U.S. The FDA prohibits a device, whether or not cleared under a 510(k) premarket notification, or approved under a pre-market approval (“PMA”) or a biologics license application, from being marketed for unapproved uses. If the FDA believes that a company is not in compliance with the regulations, it can institute proceedings to detain or seize a product, issue a recall, prohibit marketing and sales of the company’s products and assess civil and criminal penalties against the company, its officers or its employees. Furthermore, the Company plans to sell products in certain foreign countries which impose local regulatory requirements. The preparation of required applications and subsequent FDA and foreign regulatory approval process is expensive, lengthy and uncertain. Failure to comply with FDA and foreign regulatory requirements could result in civil monetary penalties or criminal sanctions, restrictions on or injunctions against marketing of the Company’s products. Additional enforcement actions may potentially include seizure or recall of the Company’s products,

and other regulatory action. There can be no assurance that the Company will be able to obtain necessary regulatory approvals or clearances in a timely manner or at all, and delays in receipt of or failure to receive such approvals or clearances, the loss of previously received approvals or clearances, or failure to comply with existing or future regulatory requirements would have a material adverse effect on the Company’s business, financial condition and results of operations.

HIV-1 Screening and Supplemental Tests

The Company’s HIV-1 screening and supplemental tests are regulated by the FDA Center for Biologics Evaluation and Research. When the screening test was submitted to the FDA in September 1992, the FDA required a product license application (“PLA”) and an establishment licensing application (“ELA”) for the Company’s Berkeley, California manufacturing facility. In August 1996, the Company received a product license and an establishment license from the FDA to manufacture and sell, in interstate and foreign commerce, the Company’s urine-based HIV-1 screening test for use in laboratory settings.

In December 1998, Calypte acquired the assets relating to the Western Blot product line of Cambridge Biotech Corporation for HIV-1. Both the urine and serum-based HIV-1 Western Blot products have received a product license and an establishment license from the FDA. In March 1999, the licenses were transferred from Cambridge Biotech Corporation to Calypte and replaced with a Biologics License (“BL”). In January 2001, the HIV-1 screening test was transferred from the biologics license to an approved PMA application concurrent with the approval of the Company’s Alameda, California manufacturing facility. In June 2001, the urine HIV supplemental Western Blot product, manufactured in the Company’s Rockville Maryland facility, was transferred from the biologics license to an approved PMA application.

Manufacturing Facilities

The FDA requires the Company’s products to be manufactured in compliance with Good Manufacturing Practices (“GMP”) regulations. In addition, the Company is subject to certain additional manufacturing regulations imposed by the State of California for the Alameda facility and the State of Maryland for the Rockville facility where the blots are manufactured. These regulations require that the Company manufacture its products and maintain related documentation for testing and control activities. The Company’s facilities and manufacturing processes have been periodically inspected by the FDA and other agencies and remain subject to audit from time to time. The Company believes that it is in substantial compliance with all applicable federal and state regulations. Nevertheless, there can be no assurance that Calypte’s manufacturing facilities will satisfy FDA, GMP or California and Maryland manufacturing requirements. Enforcement of the GMP regulations has increased significantly in the last several years, and the FDA has publicly stated that compliance will be more strictly enforced. In the event that the FDA determines the Company to be out of compliance with its regulations and to the extent that the Company is unable to convince the FDA of the adequacy of its compliance, the FDA has the power to assert penalties, including injunctions or temporary suspension of shipment until compliance is achieved. In addition, the FDA will not approve a biologics license or PMA if the facility is found in noncompliance with GMPs. Such penalties could have a material adverse effect on the Company’s business, financial condition and results of operations.

Also, the manufacturing facility in Maryland is a specialized facility incorporating Biosafety Level 3 controls for the manipulation of potentially infectious biological agents (HIV viruses) as well as the use of hazardous chemical materials. As such, this facility and the products manufactured there are subject to rigorous federal, state and local regulatory controls including registration, licensing and specific material use permits. Should it become necessary to move the Maryland operations to a different location in the future, significant costs, time and resources would likely be required to validate such a transfer and obtain the required regulatory clearances.

In addition, the manufacture, sale or use of the Company’s products are subject to regulation by other federal entities, such as the Occupational Safety and Health Agency, the Environmental Protection Agency, and

by various state agencies, including the California Environmental Protection Agency. Federal and state regulations regarding the manufacture, sale or use of the Company’s products are subject to future change, and these changes could have a material adverse effect on the Company’s business, financial condition and results of operations.

Product Liability and Recall Risk; Limited Insurance Coverage. The manufacture and sale of medical diagnostic products subjects Calypte to risks of product liability claims or product recalls, particularly in the event of false positive or false negative reports. A product recall or a successful product liability claim or claims that exceed our insurance coverage could have a material adverse effect on us. We maintain a $10,000,000 claims made policy of product liability insurance against which no claims have been made. However, product liability insurance is expensive. In the future, we may not be able to obtain coverage on acceptable terms, if at all. Moreover, our insurance coverage may not adequately protect us from liability that we incur in connection with clinical trials or sales of our products.

International

The Company’s Alameda, California manufacturing site was awarded ISO 9001/EN 46001/ ISO 13485 certification on March 14, 2001. Distribution of the Company’s products outside the United States is subject to regulatory requirements that vary from country to country. In a number of foreign countries, FDA approval is required prior to approval in that country. The export by the Company of certain of its products that have not yet been approved for domestic commercial distribution may be subject to FDA export restrictions. Approval and registration processes are underway in several countries including Brazil, South Korea, Hungary, Philippines, and Mexico. To date, in countries operating their own agencies for the evaluation and registration of HIV testing kits, the Company has received approval in Malaysia and The People’s Republic of China. Additionally, the HIV screening test has been authorized for importation into The Republic of South Africa. Failure to obtain additional regulatory approvals or failure to comply with regulatory requirements would have a material adverse effect on the Company’s business, financial condition and results of operations.

Competition

Competition in the in vitro diagnostic market is intense and expected to increase. Within the United States, the Company will face competition from a number of well-established manufacturers of blood-based HIV tests, plus at least one system for the detection of HIV antibodies using oral fluid samples. In addition, the Company may face intense competition from competitors with significantly greater financial, marketing and distribution resources than the Company.

The suppliers of blood-based HIV tests in the United States include Abbott Laboratories (“Abbott”), Biomerieux, Ortho Clinical Diagnostics (“Ortho”), a division of Johnson & Johnson, and Bio-Rad Laboratories (“Bio-Rad”). All of these companies have many years of HIV market experience, and they typically offer a number of different testing products. Abbott, Bio-Rad and Ortho currently sell FDA-licensed blood-based HIV-1/HIV-2 combination tests on the market in the United States, and other companies may be developing HIV-1/HIV-2 products. Calypte’s urine-based screening test does not include testing for HIV-2 and the Company does not currently plan to add HIV-2 screening capability to this test. In addition nucleic acid amplification testing (“NAT”), has received FDA approval for screening plasma donations. There is no consensus at this time on the use of serological testing in the NAT algorithm.

The Company believes that HIV screening tests designed to use oral fluid may offer significant competition to the Company’s urine-based HIV-1 screening test. The OraSure^™ collection device manufactured by OraSure, Inc., used in conjunction with an HIV-1 EIA manufactured by Biomerieux received FDA approval for marketing in the United States in December 1994. In June 1996, Epitope, Inc., the predecessor to OraSure, Inc., received approval from the FDA for a Western Blot oral-fluid confirmatory test.

In addition, market dynamics are expected to change with the approval and full-scale launch of Rapid HIV tests. The Centers for Disease Control and the World Health Organization are strong proponents of the benefits of rapid testing in the fight against the spread of HIV and AIDS. While not expected to eliminate the need for current HIV screening tests, it is anticipated that rapid tests will ultimately control a significant share of the worldwide testing market

The Company is not aware of any competitors which have submitted urine-based HIV screening tests to the FDA, but there can be no assurance that such tests will not be submitted in the future for approval by the FDA. The Company is aware of only one other manufacturer, Murex Corporation (“Murex”), now owned by Abbott Laboratories which has publicly announced urine capability for an HIV test. Murex manufactures a number of HIV assays in microtiter format. The Company is not aware that any of these assays have been submitted to the FDA for review. One such microtiter assay, “gacelisa,” is intended for use on saliva and urine samples but is marketed only outside of the U.S. primarily as a research assay. Murex markets one HIV product in the U.S., the FDA-licensed Single Use Diagnostic System (“SUDS”) rapid test, which is intended for use on serum and plasma only. Although urine capability for this test has been reported in scientific literature, the Company is not aware of any applications for expanded sampling claims for this assay. In addition, the SUDS assay format is not conducive to high-volume testing. Murex is also a significant customer of Calypte’s, purchasing HIV viral lysate for use in its serum-based diagnostic tests.

Essentially all of the Company’s competitors actively market their diagnostic products outside of the U.S. In addition, outside of the U.S., where the regulatory requirements for HIV screening tests are less demanding than those of the FDA, a much wider range of competitors can be found. Manufacturers from Japan, Canada, Europe, and Australia offer a number of HIV screening tests in those markets including HIV-1/HIV-2 tests, rapid tests and other non-EIA format tests, which are not approved for sale in the U.S. market. There can be no assurances that the Company’s products will compete effectively against these products in foreign markets, or that these competing products will not achieve FDA approval.

Employees

As of December 31, 2001, the Company had 66 full time employees, three of whom were engaged in or directly supported the Company’s research and development activities, 43 of whom were in manufacturing, facilities and quality assurance, ten of whom were in marketing and sales and ten of whom were in administration. The Company’s employees are not represented by a union or collective bargaining entity. The Company believes its relations with its employees are good.

Scientific Advisory Board

The Scientific Advisory Board is composed of certain of the Company’s scientists and other leading scientists who have been actively involved in pioneering HIV research. Scientific Advisory Board members meet as a group and individually with management and key scientific employees of the Company on an as-needed basis. Scientific Advisory Board members have taken an active role in helping the Company identify scientific and product development opportunities and recruiting and evaluating the Company’s scientific staff. The Company has granted options to acquire its Common Stock to members of the Scientific Advisory Board.

On February 28, 2002, there were 349 holders of record of the Common Stock, and the closing price of the Common Stock was $0.185. The Company has never paid any cash dividends, and the Board of Directors does not anticipate paying cash dividends in the foreseeable future. The Company intends to retain any future earnings to provide funds for the operation and expansion of its business.

Sales of Common Stock

Private Placement of Common Stock

In November 2001, the Company sold 1,575,855 shares of Common Stock under Regulation D of the Securities Act of 1933 (“the Securities Act”), to various investors in a private placement at $0.19 per share, receiving net proceeds of $295,000. The private placement did not include registration rights. Therefore, pursuant to Rule 144 of the Securities Act, the transfer of the securities purchased by the investors will be restricted for twelve months from the date of purchase. Three members of the Company’s Board of Directors, David Collins, Nancy Katz, and Mark Novitch, purchased an aggregate of 721,154 shares of this offering. The proceeds of this offering have been used to fund the Company’s current operations.

Subsequent Events

Private Placement of Convertible Debentures and Warrants

On February 12, 2002, the Company announced that it had signed an agreement to place up to $850,000 in two secured convertible debentures with a private investment fund in a private placement pursuant to Regulation D of the Securities Act. In conjunction with this transaction, the Company issued warrants to purchase up to 13,700,000 shares of its Common Stock. Subject to certain trading volume restrictions as defined below, the agreement obligates the fund to purchase 12,000,000 shares covered by these warrants during the twelve months following the effectiveness of a registration statement that the Company will file with the Securities and Exchange Commission to register the resale of the shares. Based on current market conditions, if the Company issues both debentures, it expects that its aggregate net proceeds from the debentures and the mandatory exercise of the warrants will amount to approximately $2.1 million.

February 12, 2002 and received $367,000 in proceeds after deducting expenses of the transaction. The Company plans to issue the second debenture when the registration statement is declared effective by the SEC. The Company expects to file the registration statement during March 2002. Each debenture will mature two years from the date of issue. Under the terms of the debentures, the investment fund can elect at any time prior to maturity to convert the balance outstanding on the debentures into shares of the Company’s common stock. Once the registration statement is declared effective, the investment fund is required to convert the debentures and to exercise the warrants each month at a rate equal to a minimum of 5% and 7.5% respectively of the trading volume in Calypte shares for the preceding 60 days. The exercise price of the warrants and the conversion price of the debentures are at floating prices that represent a discount to the trading price of the Company’s shares for the 20 trading days preceding the exercise and conversion.

Restructure of Trade Debt

On February 12, 2002, the Company completed a restructure of approximately $1.6 million of its past due accounts payable and certain 2002 obligations with 28 of its trade creditors. Under the restructuring, the Company issued approximately 1.4 million shares of its Common Stock at various negotiated prices per share with the trade creditors in satisfaction of the specified debt. The issuance of shares was exempt from registration pursuant to Regulation D of the Securities Act. The Company agreed to register the shares within 60 business days of the closing date.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following information should be read in conjunction with the consolidated financial statements and related notes that are provided under Part II, Item 8 of this Annual Report on Form 10-K.

The forward-looking information set forth in this Annual Report on Form 10-K is as of March 8, 2002, and Calypte undertakes no duty to update this information. Should events occur subsequent to March 8, 2002 that make it necessary to update the forward-looking information contained in this Form 10-K, the updated forward-looking information will be filed with the SEC in a Quarterly Report on Form 10-Q or as an earnings release included as an exhibit to a Form 8-K, each of which will be available at the SEC’s website at www.sec.gov. More information about potential factors that could affect Calypte’s business and financial results is included in the section entitled “Risk Factors” beginning on page 29 of this Form 10-K.

Overview and Outlook

Calypte’s efforts are currently focused on expanding the sales and marketing of its HIV-1 urine-based and serum-based diagnostic tests and on improving those products and their related manufacturing processes. The Company is also continuing its efforts to develop a urine-based HIV screening test in a rapid-test format and is investigating potential urine-based diagnostic tests for other diseases. Since the summer of 1998, when the Company received a license for both its screening and supplemental tests, the Company has been marketing and selling in the U.S. the only available FDA-approved urine-based HIV test method. The Company has also received regulatory approval to sell its urine-based screening test in the Peoples’ Republic of China, Malaysia, and the Republic of South Africa. In conjunction with its distributors, the Company is actively working to obtain requisite regulatory approvals to expand the distribution of its products in selected additional international markets. There can be no assurance that the Company will achieve or sustain significant revenues from sales of the HIV-1 urine screening assay or the supplemental test.

In 2001 the Company more than doubled its full-year 2000 revenues and it expects further growth in revenue in 2002. Although expecting a significant increase in revenues for the entire year, the Company does not currently expect revenues for the first quarter of 2002 to be significantly changed from revenues reported in the first quarter of 2001 due to the sporadic timing of sales of its HIV-1 viral lysate, which it sold in the first quarter of 2001, but does not expect to sell in the first quarter of 2002. The Company’s marketing strategy is to use focused direct selling, distributors, and marketing partners to penetrate targeted domestic markets. For some time, the Company has maintained a small direct sales force to market its urine-based HIV-1 tests to reference laboratories serving the life insurance market. Beginning in the first quarter of 2001, the Company expanded its direct sales force to target other domestic sectors, including public health clinics and laboratories and community based advocacy and service groups. The Company addresses international markets utilizing resident diagnostic product distributors. The Company expects operating losses to continue during 2002 as it continues to expand its sales and marketing activities for its current products domestically and internationally and conducts additional research and development for process improvements and new products. Depending on the success of international introductions of its current HIV screening and supplemental tests and the timing of new product development and regulatory testing cycles, the Company expects to achieve a small operating profit between no earlier than the fourth quarter of 2002 or perhaps as late as mid-2003. There can, however, be no assurance that the Company’s current or potential new products will be successfully commercialized or that the Company will achieve significant product revenues. In addition, there can be no assurance that the Company will achieve or sustain profitability in the future.

to any such strategic opportunity, and there can be no assurance that additional capital will be available to the Company on acceptable terms, or at all. If the Company is unable to obtain additional financing or to arrange a suitable strategic opportunity will place it in significant financial jeopardy. Although the Company began the marketing and sale in the U.S. of the only available FDA-approved urine-based HIV test methods during the summer of 1998, upon receipt of FDA approval for both its screening and supplemental tests, the Company has not yet achieved profitability based on sales of those products. There can be no assurance that the Company will achieve profitability from sales of the HIV-1 urine screening assay or the supplemental test.

Critical Accounting Policies and Estimates

Calypte’s discussion and analysis of its financial condition and results of operations are based upon Calypte’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires Calypte to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, Calypte evaluates its estimates and judgments, including those related to product returns, bad debts, inventories, intangible assets, income taxes, restructuring costs, and contingencies and litigation. Calypte bases its estimates on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Calypte believes the following critical accounting policies, among others, affect its more significant judgments and estimates used in the preparation of its consolidated financial statements. Calypte recognizes revenue from product sales upon shipment to customers and when all requirements related to the shipments have occurred. Should changes in terms cause Calypte to determine these criteria are not met for certain future transactions, revenue recognized for any reporting period could be adversely affected. Calypte maintains an allowance for doubtful accounts on a specific account identification basis for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of Calypte’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Calypte adjusts the value of its inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. Further, as the company has continued to incur negative gross profits on an annual basis, with high fixed manufacturing costs, Calypte also reviews its inventories for lower of cost or market valuation. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. Calypte records a full valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized. While Calypte has considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, in the event Calypte were to determine that it would be able to realize its deferred tax assets in the future in excess of its net recorded amount, an adjustment to the deferred tax asset would increase income in the period such determination was made.

Results of Operations

Years Ended December 31, 2001 and 2000

Calypte’s 2001 revenues totaled $6.8 million compared with $3.3 million for 2000, an increase of 107%, making 2001 the Company’s record revenue year. Screening test revenues increased by 60%. Sales of the screening test to insurance company reference labs increased by 44% due to an increase in the number of insurance companies using urine testing and, in some cases, the broadening of policy limits for which underwriters accept urine testing. International sales accounted for approximately $250,000 in screening test sales in 2001, compared to an insignificant amount in 2000. The initial screening test sales to Calypte’s Sub Saharan Africa and Chinese distributors occurred in the first quarter of 2001 and its initial sale to its Malaysian

distributor in the third quarter of 2001. A larger sale to the Chinese distributor occurred in the fourth quarter of 2001. The company completed its first South African sale in the third quarter of 2000, its only international screening test sale that year. The Company has completed a subsequent sale to its Chinese distributor early in the first quarter of 2002; however future sales to South and sub-Saharan Africa will be dependent on either the consummation of a change in ownership for the distributor, or replacement of the distributor. U.S. distributor, direct and Sentinel screening sales were not significant in either 2001 or 2000. The Company is focusing on expanding the US Diagnostic and Sentinel business during 2002.

Sales of supplemental tests and viral lysate increased 135% in 2001 compared with 2000 revenues. Urine Western Blot sales increased 70%, but from a small base in 2000. Serum Western Blot sales increased by 130% compared to 2000 levels. The increase in serum blot sales is attributable to a combination of new business from Biomerieux, which acquired Organon-Teknika shortly after Organon-Teknika discontinued production of its Western Blot product and switched its customers to Calypte’s blot, as well as to the impact of a significant price increase the third quarter of 2001. Serum Western Blot test volume increased 121% year over year and Biomerieux became Calypte’s largest customer in 2001. Sales of the Company’s HIV viral lysate, a component Calypte uses in the production of its Western Blot products and which it sporadically sells to another manufacturer of serum-based HIV diagnostic tests and other parties, increased by more than 6 times compared to 2000 levels and accounted for approximately 20% of 2001 revenues. During the second quarter of 2001, the primary customer for the viral lysate expressed concern regarding the viability of Calypte as a continuing supplier and increased its orders with the intent of stockpiling. Although Calypte continues to expect orders for viral lysate from this customer in the future, potentially as early as the second quarter of 2002, it does not expect 2002 orders to be at the level of 2001 orders. As a result of the increased viral lysate orders, this customer became Calypte’s second largest in 2001. In total, Calypte’s significant, greater than 10% customers, accounted for 57% (3 customers) of total sales in 2001, compared with 42% (3 customers) in 2000.

Gross margin improved steadily throughout 2001, culminating in a full-year loss of 2% for 2001 compared with a loss of 79% in 2000. A number of factors contributed to this critical improvement in Calypte’s operations. First, the increased level of sales of both screening and supplemental tests helped to mitigate the effect of underutilized facilities burdened with high fixed costs. Once fixed manufacturing costs are covered, the company enjoys a significant contribution margin on the incremental volume. That phenomenon was demonstrated during 2001 at both manufacturing facilities. Second, the closure of the Berkeley facility in February 2001 contributed to the improvement, avoiding approximately $300,000 in redundant facility costs, as did general reductions in other controllable costs, including payroll costs, in response to the company’s difficult financial situation. Additionally, a reduction in validation and calibration costs at the Alameda facility following FDA inspection and approval compared to the 2000 level also contributed to the margin improvement. Third, a significant price increase on serum blots at the beginning of the third quarter contributed to improved margins during the last half of the year. Last, the increase in viral lysate sales, and their accompanying higher margins compared with those achieved from sales of either screening or supplemental tests, significantly improved the overall margin on sales compared to prior year. As noted previously, the impact of viral lysate sales will not recur in 2002 at the level experienced in 2001, however the facility consolidation project at Rockville in the first quarter of 2002 will have an impact similar to that of the closure of the redundant Berkeley facility in 2001 to partially mitigate the absence of viral lysate sales.

R&D costs decreased 31% from $2,254,000 in 2000 to $1,546,000 in 2001. Approximately one third of the decrease is attributable to the discontinuation of the pure research function early in 2001 when Calypte’s founder left the Company to pursue his interests in a genomics venture. Approximately half of the decrease is attributable to the cessation of the facility validation and related consulting expenses incurred in 2000 in preparation for the FDA inspection of the Alameda facility. The remainder of the reduction is attributable to lower contract and consultant fees for the development of potential new products. Because of the Company’s cash flow constraints during 2001, only the in-house development and collaboration on the HIV rapid test was pursued. Collaboration with a university on a urine-based screening test for another infectious disease that had commenced in 2000 was not pursued in 2001.

Selling, general and administrative costs decreased from $7,568,000 in 2000 to $6,740,000 in 2001, a decrease of 11%. The 2001 figures include a $156,000 provision for the uncollectibility of the South African distributor receivable arising from a first quarter 2001 sale. Absent this one-time charge, the decrease would have been 13%. Expense for 2001 reflects the increased compensation costs attributable to the Company’s expanded domestic sales force, replacing the distributor organization utilized in 2000. As a result of the significant reduction in spending beginning in the second quarter of 2001, full-year marketing consultants expense has decreased by 37% versus 2000. The company continued its efforts to stimulate awareness of its presence and products among Community Based and AIDS Service Organizations through limited educator and outreach programs, but essentially eliminated all other outside programs and advertising during the last three quarters of 2001. Administrative consultants, including public relations, government relations, and investor relations efforts were also eliminated or assumed in-house in an effort to minimize expenses. Further contributing to the 2001 decrease in selling, general and administrative expenses is a reduction in the Alameda facility cost recognized as an administrative expense; since that facility has achieved FDA approval, a larger share of costs are recognized as a component of manufacturing expense.

The loss from operations for 2001, at $8,446,000, reflects a 32% reduction of the $12,417,000 loss reported for 2000.

Interest income decreased by 97% in 2001 compared to 2000. The Company had completed an $8.4 million private placement of its common stock early in the second quarter of 2000 and had considerably higher invested cash balances in 2000 than during 2001. Interest expense increased from $123,000 in 2000 to $1,373,000 for 2001. Of the 2001 interest expense, $1,318,000 reflects non-cash charges relating to amortization of equity line offering costs, conversion feature and original issue discount costs attributable to the convertible debentures and similar costs of the financing vehicles the Company employed in the first half of 2001. Other income in 2001 relates to the $500,000 gain on the second quarter sale of the Company’s equity interest in Pepgen Corporation, a privately-held development-stage therapeutic research and drug development company, and the gain on the sale of fully depreciated assets from the Berkeley facility upon its closure and in anticipation of the Rockville space consolidation project.

Years Ended December 31, 2000 and 1999

Calypte’s sales revenues decreased 12% from $3.7 million for the year ended December 31, 1999 to $3.3 million for the year ended December 31, 2000. Sales of Calypte’s screening test were essentially unchanged between years. The impact of so-called “Triple X” legislation, which essentially eliminated the availability of 30-year life insurance policies after 1999, caused noticeable increases in fourth quarter 1999 and first quarter 2000 revenues as testing associated with final applications for 30-year policies was completed. International sales of the Company’s screening test were insignificant in 2000. Sales of the Company’s Western Blot supplemental tests declined in 2000 versus 1999, following a trend experienced for the past few years. Increased sensitivity and specificity of screening tests and international testing algorithms that do not always require a supplemental test continue to make the supplemental test market a declining one.

Product costs increased from $4.7 million in 1999 to $5.9 million in 2000, an increase of 25%. Product costs for the Company’s screening test decreased slightly versus 1999 levels, primarily due to the requirement to produce non-saleable validation inventory at the Company’s Alameda manufacturing facility in 1999 in anticipation of the facility’s inspection and approval. Although the facility did not produce non-saleable validation inventory in 2000, the Company did incur duplicative costs for the operation of both its Alameda and Berkeley screening test production facilities throughout 2000. Product costs at the Company’s supplemental test manufacturing facility increased noticeably in 2000 compared to 1999 as the Company added personnel and made significant expenditures to correct FDA inspection observation conditions and ensure compliance with FDA and good manufacturing practices requirements.

Research and development expenses decreased from $4.1 million in 1999 to $2.3 million in 2000, a 45% decrease. Included in 1999 research and development expense was the $1.0 million write-off of a note receivable

and accrued interest from Pepgen. In 2000, the Company also renegotiated one of its license agreements, significantly reducing the minimum annual payment under the agreement that had been expensed as research and development. The Company also experienced a reduction in the cost of clinical studies applicable to the FDA approval for its Alameda facility during 2000.

Selling, general and administrative expenses increased in 2000 by 49% compared to 1999, from $5.1 million to $7.6 million. The increase was primarily attributable to beginning commercialization initiatives designed to increase awareness of the Company and its products among targeted audiences, including government agencies and programs, public health, AIDS activist, and community–based outreach groups, and within the investment community. The Company also increased its use of consultants and other outside service providers in projects as diverse as developing a new website to defining its most attractive potential international markets. In conjunction with securing new international distribution agreements, the Company also incurred an increased level of travel and related costs in 2000.

Interest income decreased slightly in 2000 as a result of lower invested cash balances compared to 1999. Interest expense also decreased slightly in 2000 as a result of scheduled principal repayments under the bank term loan agreement and the capital lease obligations.

Liquidity and Capital Resources

Financing Activities

The Company has financed its operations from its inception primarily through the private placement of preferred stock and common stock, its Initial Public Offering (IPO) of common stock and, to a lesser extent, from payments related to research and development agreements, a bank line of credit, equipment lease financings and borrowings from notes payable.

In January 1999, the Company completed a private placement of 3,102,500 shares of Common Stock to institutional investors at $1.00 per share. Calypte received net proceeds of approximately $3.1 million after deducting placement agent commissions and additional expenses associated with the private placement.

In April 1999, the Company completed a private placement of 3,398,000 shares of its Common Stock to institutional investors at $2.25 per share. Calypte received net proceeds of approximately $6.8 million after deducting agent commissions and additional expenses associated with the private placement.

In January 1999, the Company entered into a loan agreement with a bank to borrow up to $2.0 million at an interest rate of prime plus 1¹/₄%. The agreement required the Company to maintain certain financial covenants and comply with certain reporting and other requirements. In addition, the Company’s assets secured its borrowings under the agreement. In January 2000, the loan was modified to extend the repayment term through August 2000. In May 2000, the loan was again modified to increase the then outstanding principal balance by $250,000. At December 31, 2000 the Company had $471,000 outstanding under this facility. The loan was repaid in full in January 2001.

In April 2000, the Company completed a private placement of 4,096,000 shares of its Common Stock at $2.05 per share. The Company received proceeds of approximately $8.3 million, after deducting expenses associated with the transaction. In connection with a bridge loan of $1 million from one of the investors, Calypte also issued warrants for 100,000 shares of Common Stock with an exercise price of $3.62 per share. The bridge loan was converted to equity upon closing of the private placement.

On January 22, 2001, the Company signed an agreement to place up to $1.1 million in convertible short-term debentures. Under this arrangement, the Company issued two convertible debentures to the debentureholder in the principal amount of $550,000 each. Each debenture had an interest rate of 6% and was issued at an original

issue discount of 9.1%. The Company issued the first debenture on January 26, 2001 and the second on March 13, 2001. Each debenture matured 90 days from the date of issuance, or on April 26, 2001 and June 11, 2001, respectively. Under the terms of the debentures, the debentureholder could elect at any time prior to maturity to convert the balance outstanding on the debentures into shares of the Company’s common stock at a fixed price that represented a 5% discount to the average trading price of the shares for the 10 trading days preceding the issuance of each debenture. If the Company chose not to redeem the debentures upon maturity, as in the case of the second debenture, the conversion discount to the debentureholder increased to 15% of the average low bid price for the Company’s common stock for any three of the 22 trading days prior to the date of conversion. Concurrent with the issuance of the first debenture, the Company also issued a warrant to the debentureholder for 200,000 shares of common stock at an exercise price of $1.50. The Company received aggregate net proceeds from the issuance of the two debentures of $925,000 during the first quarter of 2001. The Company redeemed the first debenture, plus accrued interest, prior to its contractual maturity using the proceeds from the sales of its common stock. The Company also redeemed a portion of the second debenture prior to its contractual maturity. On June 12, 2001, the debentureholder converted the remaining $168,000 balance on the second debenture plus accrued interest into 1,008,525 shares of the Company’s Common Stock, in accordance with the conversion provisions of the debenture. On August 17, 2001, the Company modified the warrant that it had issued to the debentureholder pursuant to the terms of the warrant, reducing its exercise price to $0.15 per share, and the debentureholder exercised it for the entire 200,000 shares. The Company received $28,500 in net proceeds from the exercise of the warrants.

On January 24, 2001 the Company amended a common stock purchase agreement for the issuance and purchase of its common stock. The initial closing of the transaction took place on November 2, 2000. The stock purchase agreement established what is sometimes termed an equity line of credit or an equity draw down facility. The facility generally operated as follows. The investor committed up to $25 million or up to 20% of the Company’s outstanding shares to purchase the Company’s common stock over a twelve-month period. Once during each draw down pricing period, the Company could request a draw, subject to a formula based on the Company’s average stock price and average trading volume setting the maximum amount of the request for any given draw. The amount of money that the investor provided to the Company and the number of shares the Company issued to the investor in return for that money was settled during a 22 day trading period following the draw down request based on the formula in the stock purchase agreement. The investor received a 5% discount to the market price for the 22 day period and the Company received the settled amount of the draw down. By June 30, 2001, the Company had issued 5,085,018 shares of its common stock, the total number registered for the equity line with the Securities and Exchange Commission, at an average price of $0.42 per share and had received net proceeds of approximately $2,014,000 after deducting expenses of the transactions. This equity line transaction is now completed. The terms of the convertible debentures discussed earlier required that 50% of the net proceeds of any equity sales, including sales under the equity draw down facility, be used to repay the debentures and related accrued interest. Accordingly, approximately $938,000 of the net proceeds from sales under the equity draw down facility was used to pay down the debentures. In conjunction with the agreement, the Company issued a 3-year warrant to the investor to purchase up to 1,000,000 shares of its stock at an exercise price of $1.55 per share. On August 2 and August 8, 2001, the Company modified the exercise price for 300,000 shares each of the warrants pursuant to the terms of the warrant, to $0.20 per share, and the investor exercised it for an aggregate of 600,000 shares. The Company received $114,000 in net proceeds from the exercise of these warrants. On August 21, 2001, the Company modified the exercise price for the remaining 400,000 shares of the warrant to $0.15 per share. The investor exercised the remaining balance of the warrant and the Company received net proceeds of $57,000 after deducting expenses of the transaction.

In April 2001, the Company announced that it had concluded negotiations to sell its 29% minority interest in the stock of Pepgen Corporation, a privately held therapeutic company, for $500,000. The Company received the proceeds from the sale in two installments in April and May 2001.

due no later than September 14, 2001. In December 2001, the parties agreed to execute a new note in the amount of $411,000, representing the unpaid principal and accrued but unpaid interest on the previous note. This note bears interest at 8.5% and was due in installments of $200,000 on February 28, 2002 and $35,000 per month thereafter until paid in full, plus accrued interest. The repayment terms of the Note were renegotiated in February 2002. The Note now requires payments of $17,500 at the end of February and March 2002, increasing to $35,000 monthly thereafter unless and until the Company raises at least $2 million in external financing, not including the convertible debentures and warrants discussed below. If there is a remaining balance under the Note upon the Company’s obtaining proceeds of at least $2 million of external financing, the Company is obligated to repay $200,000 on the note and should any balance on the Note remain thereafter, the Company is obligated to continue monthly payments of $35,000 until the Note is repaid in full. The Company made the required $17,500 payment on February 28, 2002.

On August 23, 2001, the Company and a private investment fund signed a common stock purchase agreement for the future issuance and purchase of up to $10 million of the Company’s Common Stock over a twenty-four month period. The initial closing of the transaction occurred on October 19, 2001. Under this arrangement, the Company, at its sole discretion, may draw down on this facility, sometimes termed an equity line, from time to time, and the investment fund is obligated to purchase shares of the Company’s Common Stock. The new facility operates similarly to the previous equity line facility employed earlier in the year. The purchase price of the Common Stock purchased pursuant to any draw down under this facility will be equal to 88% of the daily volume weighted average price of the Company’s Common Stock on the applicable date. In conjunction with the signing of the stock purchase agreement, on October 19, 2001, the Company issued a 7-year warrant to the investment fund to purchase up to 4,192,286 shares of Common Stock at an exercise price of $0.2743 per share. On October 26, 2001, the Company filed a Registration Statement on Form S-2 with the Securities and Exchange Commission to register for resale 30,000,000 shares of Common Stock that it may issue in conjunction with the equity line facility and the warrant. Since the Registration Statement became effective in November 2001 through December 31, 2001, the Company issued a total of 2,182,144 shares of its common stock at an average price of $0.197 per share and received net proceeds of approximately $406,000 after deducting expenses of the transactions. Between January 1 and March 1, 2002, the Company has issued an additional 4,094,461 shares of its common stock at an average price of $0.176 and received net proceeds of $679,000 after deducting expenses.

In November 2001, the Company sold 1,575,855 shares of Common Stock under Regulation D of the Securities Act to various investors in a private placement at $0.19 per share, receiving net proceeds of $295,000. The private placement did not include registration rights. Therefore, pursuant to Rule 144 of the Securities Act, the transfer of the securities purchased by the investors will be restricted for twelve months from the date of purchase. Three members of the Company’s Board of Directors purchased an aggregate of 721,154 shares of this offering.

On November 28, 2001, Calypte announced that it intended to offer up to $10 million of shares of its common stock to international investors pursuant to Regulation S of the Securities Act. The offering is being conducted exclusively outside of the U.S. and will be open only to non-U.S. persons under Regulation S. The Company expects the offering to conclude during the first quarter of 2002. The Company can give no assurances that any or all of the amount of equity being offered will be sold. In the event that the Regulation S offering is not completed to the Company’s satisfaction, the Company will have to seek additional financing.

Subsequent Events

Private Placement of Convertible Debentures and Warrants

On February 12, 2002, the Company announced that it had signed an agreement to place up to $850,000 in two secured convertible debentures with a private investment fund. In conjunction with this transaction, the Company issued warrants to purchase up to 13,700,000 shares of its Common Stock. Subject to certain trading

volume restrictions as defined below, the agreement obligates the fund to purchase 12,000,000 shares covered by these warrants during the twelve months following the effectiveness of a registration statement that the Company will file with the Securities and Exchange Commission to register the resale of the shares. Based on current market conditions, if the Company issues both debentures, it expects that its aggregate net proceeds from the debentures and the mandatory exercise of the warrants will amount to approximately $2.1 million. Under this arrangement, the Company will issue two secured convertible debentures to the investment fund with a principal amount of $425,000 each at a 12% interest rate. The Company issued the first debenture on February 12, 2002 and received $367,000 in proceeds after deducting expenses of the transaction. The Company plans to issue the second debenture when the registration statement is declared effective by the SEC. The Company expects to file the registration statement during March 2002. Each debenture will mature two years from the date of issue. Under the terms of the debentures, the investment fund can elect at any time prior to maturity to convert the balance outstanding on the debentures into shares of the Company’s common stock. Once the registration statement is declared effective, the investment fund is required to convert the debentures and to exercise the warrants each month at a rate equal to a minimum of 5% and 7.5% respectively of the trading volume in Calypte shares for the preceding 60 days. The exercise price of the warrants and the conversion price of the debentures are at floating prices that represent a discount to the trading price of the Company’s shares for the 20 trading days preceding the exercise and conversion.

Restructure of Trade Debt

The Company does not believe that its currently available financing will be adequate to sustain operations at current levels through the second quarter of 2002, or to permit it to achieve the revenue and profitability guidance provided previously, and it does not know if it will succeed in raising funds through its ongoing offering of equity securities to overseas investors pursuant to Regulation S. The Company must achieve profitability for its business model to succeed. Prior to accomplishing this goal, it will need to raise additional funds, from equity or debt sources. The Company believes that it may need to arrange additional financing of approximately $5 million in the next twelve months because amounts available under its October 2001 equity line and the convertible debentures and warrants that it agreed to issue in February 2002 may not be sufficient to meet its cash needs in the future. In addition, business and economic conditions may make it unfeasible or undesirable to draw down under the equity line of credit at every opportunity, and only one draw down may occur at a time. If additional financing is not available when required or is not available on acceptable terms, the Company may be unable to continue its operations at current levels. As of December 31, 2001, the Company reported cash on-hand of $287,000. During the fourth quarter of 2001, cash receipts exceeded cash expenditures by $239,000, but trade payables and accrued expenses increased by $274,000. The Company is actively engaged in seeking additional financing in a variety of venues and formats and continues to impose actions designed to minimize its operating losses. The Company would consider strategic opportunities, including investment in the Company, a merger or other comparable transaction, to sustain its operations. The Company does not currently have any agreements in place with respect to any such strategic opportunity, and there can be no assurance that additional capital will be available to the Company on acceptable terms, or at all. The Company’s inability to obtain additional financing or to arrange a suitable strategic opportunity will place it in significant financial jeopardy.

The Company’s future liquidity and capital requirements will depend on numerous factors, including the ability to raise additional capital in a timely manner through additional investment, a potential merger, or similar transaction, as well as expanded market acceptance of its current products, improvements in the costs and efficiency of its manufacturing processes, its ability to develop and commercialize new products, regulatory actions by the FDA and other international regulatory bodies, and intellectual property protection.

There can be no assurance that the additional capital that the Company requires will be available on acceptable terms, if at all. Any failure to secure additional financing will place the Company in significant financial jeopardy. Therefore, the Company cannot predict the adequacy of its capital resources on a long-term basis. There can be no assurance that the Company will be able to achieve improvements in its manufacturing processes or that it will achieve significant product revenues from its current or potential new products. In addition, there can be no assurance that the Company will achieve or sustain profitability in the future.

Operating Activities

For the years ended December 31, 2001 and 2000, the Company’s cash used in operations was $4.1 million and $10.7 million, respectively. The $6.6 million reduction in cash used in operations is the result of three primary factors:

•

specific cost reduction initiatives, including salary and headcount reductions, designed to reduce operating costs and expenses;

•

the increase in revenues from product sales; and

•

a $3.3 million increase in accounts payable and accrued expenses resulting from the Company’s delay in timely payment to its suppliers due to its limited cash availability.

The cash used in operations was primarily for promoting and marketing the company’s complete urine HIV-1 testing method, for manufacturing, and for research, selling, and general and administrative expenses of the Company.

Recent Accounting Pronouncements

In July 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards (SFAS) No. 141 “Business Combinations” and SFAS No. 142 “Goodwill and Other Intangible Assets.”

SFAS No. 141 addresses the accounting for and reporting of business combinations and requires that all business combinations be accounted for using the purchase method of accounting for acquisitions and eliminates the use of the pooling method. This Statement applies to all business combinations initiated after June 30, 2001. The Company does not expect that the adoption of SFAS No. 141 will have a material effect on its consolidated financial statements.

SFAS No. 142 addresses financial accounting and reporting for acquired goodwill and other intangible assets. This Statement changes the accounting for goodwill from an amortization method to an impairment-only method. The amortization of goodwill, including goodwill recorded in past business combinations will cease upon adoption of this Statement, which will begin with the Company’s fiscal year beginning January 1, 2002. However, goodwill and intangible assets acquired after June 30, 2001 will be subject to immediate adoption of the Statement. The Company does not expect that the adoption of SFAS No. 142 will have a material effect on its consolidated financial statements.

In July 2001, the FASB issued SFAS No. 143, “ Accounting for Asset Retirement Obligations.” SFAS No. 143 requires liability recognition for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. The Company is required to adopt the provisions of SFAS No. 143 beginning with its fiscal year that starts January 1, 2003. The Company does not expect that adoption of SFAS 142 will have a material effect on its consolidated financial statements.

and for Long-Lived Assets to Be Disposed Of”, in that it removes goodwill from its impairment scope and allows for different approaches in cash flow estimation. However, SFAS No. 144 retains the fundamental provisions of SFAS No. 121 for (a) recognition and measurement of long-lived assets to be held and used and (b) measurement of long-lived assets to be disposed of. SFAS No. 144 also supersedes the business segment concept in APB Opinion No. 30, “Reporting the Results of Operations-Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions,” in that it permits presentation of a component of an entity, whether classified as held for sale or disposed of, as a discontinued operation. However, SFAS No.144 retains the requirement of APB Opinion No. 30 to report discontinued operations separately from continuing operations. The Company is required to adopt the provision of SFAS No. 144 beginning with its fiscal year that starts January 1, 2002. The Company does not believe that adoption of SFAS 144 will have a material effect on its consolidated financial statements.

Risk Factors

Calypte has identified a number of risk factors faced by the Company. These factors, among others, may cause actual results, events or performance to differ materially from those expressed in any forward-looking statements made in this Form 10-K or in press releases or other public disclosures. Investors should be aware of the existence of these factors.

Risks Related to Our Financial Condition

If We are Unable to Obtain Additional Funds We May Have to Significantly Curtail the Scope of our Operations and Alter our Business Model.

We do not believe that our currently available financing will be adequate to sustain operations at current levels through the second quarter of 2002, or to permit us to achieve the revenue and profitability guidance provided previously, and we do not know if we will succeed in raising funds through our ongoing offering of equity securities to overseas investors pursuant to Regulation S. We must achieve profitability for our business model to succeed. Prior to accomplishing this goal, we will need to raise additional funds, from equity or debt sources. We believe that we may need to arrange additional financing of approximately $5 million in the next twelve months because amounts available under our October 2001 equity line and the convertible debentures and warrants that we agreed to issue in February 2002 may not be sufficient to meet our cash needs in the future. In addition, business and economic conditions may make it unfeasible or undesirable to draw down under the equity line of credit at every opportunity, and only one draw down may occur at a time. If additional financing is not available when required or is not available on acceptable terms, we may be unable to continue our operations at current levels. As of December 31, 2001, our cash on-hand was $287,000. During the fourth quarter of 2001, cash receipts exceeded cash expenditures by $239,000, but trade payables and accrued expenses increased by $274,000. We are actively engaged in seeking additional financing in a variety of venues and formats and we continue to impose actions designed to minimize its operating losses. We would consider strategic opportunities, including investment in the Company, a merger or other comparable transaction, to sustain its operations. We do not currently have any agreements in place with respect to any such strategic opportunity, and there can be no assurance that additional capital will be available to us on acceptable terms, or at all. Our inability to obtain additional financing or to arrange a suitable strategic opportunity will place us in significant financial jeopardy.

Our Independent Auditors have Stated that Our Recurring Losses from Operations and our Accumulated Deficit Raise Substantial Doubt about our Ability to Continue as a Going Concern.

The report of KPMG LLP dated February 8, 2002 covering the December 31, 2001 consolidated financial statements contains an explanatory paragraph that states that our recurring losses from operations and accumulated deficit raise substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. We will need to raise more money to continue to finance our operations. We may not be able to obtain additional

financing on acceptable terms, or at all. Any failure to raise additional financing will likely place us in significant financial jeopardy.

Our Financial Condition has Adversely Effected Our Ability to Pay Suppliers, Service Providers and Licensors on a Timely Basis which may Jeopardize our Ability to Continue our Operations and Maintain License Rights Necessary to Continue Shipments and Sales of our Products

As of December 31, 2001, our accounts payable totaled $4.1 million, of which $3.7 million were over 60 days old. We have been engaged in negotiations with our creditors to restructure and reschedule our payments. On February 12, 2002, we closed a restructuring of approximately $1.6 million of our trade debt and royalty payments, pursuant to which 28 creditors agreed to discharge such debt in exchange for a total of approximately 1.4 million shares of our Common Stock. However, if we are unable to obtain additional financing on acceptable terms, our ability to make timely payments to our critical suppliers, service providers and to licensors of intellectual property used in our products will be jeopardized and we may be unable to obtain critical supplies and services and to maintain licenses necessary for us to continue to manufacture, ship and sell our products.

Calypte and the Price of Our Shares May be Adversely Affected By the Public Sale of a Significant Number of the Shares Eligible for Future Sale.

All but a very small number of the outstanding shares of our Common Stock are freely tradable. Sales of Common Stock in the public market could materially adversely affect the market price of our Common Stock. Such sales also may inhibit our ability to obtain future equity or equity-related financing on acceptable terms.

At our Annual Meeting of Stockholders on September 20, 2001, our stockholders approved an increase in the number of authorized shares of the Company’s Common Stock from 50 million to 200 million. In addition to the shares that we are issuing to the investors pursuant to the equity line and the convertible debentures and warrants, we may also issue up to $10 million worth of shares pursuant to the Regulation S offering. If we are unable to successfully conclude the Regulation S offering, we expect that it will be necessary to issue a significant number of these newly authorized shares pursuant to potential agreements to finance our operations over the next several quarters. The registration and issuance of these shares pursuant to a future financing arrangement could have a significant adverse affect on the trading price of our Common Stock.

The Sale of Material Amounts of our Common Stock to Finance the Continuing Operations of the Company and the Eligibility of Issued Shares for Resale May Substantially Dilute Our Common Stock and Place Significant Downward Pressure on its Trading Price.

Our need to raise funds through the sale of equity in the Company will likely result in the issuance of a significant number of shares of Common Stock in relation to the number of shares currently outstanding. In the past, we have raised money through the sale of shares of our Common Stock at a discount to the current market price. Such arrangements have included the private sale of shares to investors on the condition that we register such shares for resale by the investors to the public. These arrangements have taken various forms including Private Investments in Public Equities, or “PIPE” transactions, equity lines of credit such as those we have utilized this year, and convertible debentures and warrants. We expect that the additional financing arrangements we are currently considering, including the Regulation S offering, will take similar forms to such prior financing arrangements. Moreover, the perceived risk of dilution may cause our existing stockholders and other holders to sell their shares of stock, which would contribute to a decrease in our stock price. In this regard, significant downward pressure on the trading price of our stock may also cause investors to engage in short sales, which would further contribute to significant downward pressure on the trading price of our stock.

We Have Incurred Losses in the Past and We Expect to Incur Losses in the Future.

We have incurred losses in each year since our inception. Our net loss for the year ended December 31, 2001 was $9.1 million and our accumulated deficit as of December 31, 2001 was $88.2 million. We expect operating losses to continue for up to the next seven quarters as we continue our marketing and sales activities for our FDA-approved products and conduct additional research and development for product and process improvements and new products.

Risks Related to the Equity Line of Credit and the Convertible Debentures and Warrants Agreement (the “Recent Financings”)

If the Price or the Trading Volume of our Common Stock Does Not Reach Certain Levels, We Will Be Unable to Draw Down All or Substantially All of the Expected Proceeds under the Recent Financings, Which May Force Us to Significantly Curtail the Scope of our Operations and Alter our Business Plan.

The maximum amount of a draw down under the equity line facility is equal to a formula based upon the weighted average price for our Common Stock and its trading volume during the 60 calendar day period immediately prior to the date that we deliver notice to the investor of our intention to exercise a draw down, multiplied by the number of days in the draw down period. We are allowed to exceed the maximum draw down amount only if we agree to set the minimum threshold price of the draw down, which is the stock price below which we will not draw down on the equity line, at 80% of the average of the five daily volume weighted average prices immediately prior to the issuance of the draw down notice. Days on which the price of our Common Stock is less than the minimum threshold price will be excluded from the calculation of the draw down amount and will therefore reduce the amount of funds that we may draw down. Additionally, the investment fund is required to convert a portion of the debentures and exercise certain of the warrants each month based on a formula determined by the trading volume of our Common Stock for the preceding 60 days.

As a result, if our stock price and trading volume fall below certain levels, then either the maximum draw down amount formula or the mandatory threshold price will probably prevent us from being able to draw down all $10 million pursuant to the equity line facility. For example, during the 60 calendar day period ended October 19, 2001, our weighted average stock price was $0.24 per share and our total trading volume was approximately 10.28 million shares. Based on those stock price and trading volume levels during such period, the maximum draw down amount available to us over the two-year term of the equity line facility would be approximately $4.4 million. Even if we exceeded the maximum draw down amount available, the mandatory threshold price would be likely to reduce the amount actually purchased at the end of the pricing period. Accordingly, our stock price and the trading volume of our stock will have to increase substantially in the future in order for us to have access to the full $10 million under the equity line. Additionally, if our trading volume and stock price do not increase, the investment fund may not entirely convert the debentures or completely exercise the warrants, and we may not receive the entire $2.1 million in expected proceeds from these transactions. If we are unable to draw down the full $10 million under the equity line or realize the expected proceeds of the debentures and warrants, we may have to curtail the scope of our operations as contemplated by our business plan.

The amount of funds that we may receive upon exercise of the Class B Warrants issued in conjunction with the convertible debentures is likewise limited by our trading volume. The debentureholder is obligated to convert the debentures each month at a rate that will result in the exercise of a number of warrants equal to at least 7¹/2% of the trading volume of our shares for the 60 days immediately preceding the conversion. Accordingly, if the trading volume of our shares does not reach certain levels and our stock price does not increase, it will reduce the number of warrants that the debentureholder will exercise upon conversion and reduce the amount of funds that we may receive upon exercise of the warrants.

Our Recent Financings and the Issuance of Shares to the Investors Pursuant to the “Recent Financings” May Cause Significant Dilution to our Stockholders and May Have a Negative Impact on the Market Price of our Common Stock.

The resale by the investors of the Common Stock that they purchase from us will increase the number of our publicly traded shares, which could put downward pressure on the market price of our Common Stock. Moreover, as all the shares we sell to the investors will be available for immediate resale, the mere prospect of our sales to the investors could depress the market price for our Common Stock. The shares of our Common Stock issuable to the investor under the equity line facility will be sold at 88% of the daily volume weighted average price of our Common Stock on the date of purchase subject to adjustment if our market capitalization increases significantly. The proceeds paid to us upon each draw down will be net of a 5% placement fee to Ladenburg Thalmann & Co., the investment bank that introduced us to the investor. If we were to require the investor to purchase our Common Stock at a time when our stock price is low, our existing Common Stockholders will experience substantial dilution. Further, we are required to draw the maximum allowable amount under the equity line equal to the amount raised through the convertible debt ($850,000) and warrant exercises.

Similarly, the shares of our Common Stock issuable to the debentureholder upon conversion of the debenture will be converted at a conversion price equal to 70% of the 3 lowest trading prices of our Common Stock during the 20 trading days immediately preceding the conversion and the warrant shares issuable pursuant to the exercise of the Class B warrants will be issued at an exercise price equal to 75% of the 3 lowest trading prices of our Common Stock during the same period. Following effectiveness of the registration statement for the shares underlying the debentures and warrants, the debentureholder is obligated to convert the debentures each month at a rate that will result in the issuance of a number of shares equal to at least 5% of the trading volume of shares of our Common Stock for the preceding 60 trading days and to exercise the Class B warrants at a rate equal to at least 7.5% of such trading volume. The issuance of shares to the investors may therefore dilute the equity interest of existing stockholders and could have an adverse effect on the market price of our Common Stock.

In addition, depending on the price per share of our Common Stock during the life of the Recent Financings, we may need to register additional shares for resale to access the full amount of financing available, which could have a further dilutive effect on the value of our Common Stock.

The perceived risk of dilution may cause our stockholders to sell their shares, which would contribute to a downward movement in the stock price of our Common Stock. Moreover, the perceived risk of dilution and the resulting downward pressure on our stock price could encourage investors to engage in short sales of our Common Stock. By increasing the number of shares offered for sale, material amounts of short selling could further contribute to progressive price declines in our Common Stock.

We Cannot Determine the Precise Amount by Which the Interests of Other Security Holders Will Be Diluted by Draw Downs and Exercises Under the Recent Financings Because the Number, Size and the Timing of Draw Downs, Debt and Warrant Conversions, and the Minimum Threshold Price for Each Depends Upon a Number of Factors.

We have substantial discretion as well as mandatory requirements over the number, size and timing of the draw downs and debt and warrant conversions that will occur under the Recent Financings. In addition, when we are not subject to mandatory draw downs under the equity line, at the time we make a draw down request, we have the right to limit the amount of dilution that will occur by setting a minimum threshold price below which shares may not be sold in that draw down. However, if we set the minimum threshold price at a level high enough to limit the sale of our shares, the amount of funds we can raise in that draw down will also be reduced. Some of the factors that we will consider in determining the size and amount of each draw down and the minimum threshold price are:

•

our short-term and long-term operating capital requirements;

•

our actual and projected revenues and expenses;

•

our assessment of general market and economic conditions;

•

our assessment of risks and opportunities in our targeted markets;

•

the availability and cost of alternative sources of financing; and

•

the trading price of our Common Stock and our expectations with respect to its future trading price.

Our discretion with respect to the number, size and timing of each draw down request is also subject to a number of contractual limitations. Similarly, the debentureholder may be issued shares upon conversion of the debentures and exercise of the warrants at a minimum monthly rate equal to 5% and 7.5% respectively of the trading volume of our Common Stock for the 60 trading days equal to such conversion up to a maximum of 2 million shares per month, subject to waiver of such limitation by the Company.

We Cannot Determine the Precise Amount by Which the Interests of Other Security Holders Will be Diluted by our Sales Under the Recent Financings Because the Number of Shares We Will Sell Depends Upon the Trading Price of the Shares During each Draw Down and Conversion Period.

The number of shares that we will sell is directly related to the trading price of our Common Stock during each draw down and debt conversion period. As the price of our Common Stock decreases, and if we decide to or are required to draw down on the equity line of credit, we will be required to issue more shares of our Common Stock for any given dollar amount invested by the investor. Similarly, the number of shares issuable under the debt conversion increases as the trading price of our Common Stock decreases although such number of shares is subject to a minimum equal to 5% and 7¹/2% for the convertible debentures and Class B warrants, respectively, of the trading volume for the 60 trading days immediately preceding the date of conversion and to a maximum of 2 million shares per month, for the Class B warrants, which maximum may be waived by the Company. Accordingly, investors may find it difficult to predict the number of shares of our Common Stock that will be sold on the public market and which may adversely affect the market price of our Common Stock.

The Sale of Material Amounts of our Common Stock Could Reduce the Price of our Common Stock and Encourage Short Sales.

As we sell shares of our Common Stock to the investors pursuant to the Recent Financings and then the investors sell the Common Stock, our Common Stock price may decrease due to the additional shares in the market. As the price of our Common Stock decreases, and if we or as we decide to draw down on the equity line of credit, and as we are required to convert from debt to equity under the Convertible Debt facility, we will be required to issue more shares of our Common Stock for any given dollar amount invested by the investor. This may encourage short sales, which could place further downward pressure on the price of our Common Stock.

Because the Investors in the Recent Financings are Residents of a Foreign Country, It may be Difficult or Impossible to Obtain or Enforce Judgments Against Them and the Investors are also Subject to United States and Foreign Laws that Could Affect our Ability to Access the Funds.

The investors are off-shore residents and a substantial portion of their assets are located outside of the United States. As a result, it may be difficult or impossible to effect service of process on the Investors within the United States. It may also be difficult or impossible to enforce judgments entered against the Investors in courts in the United States based on civil liability provisions of the securities laws of the United States. In addition, judgments obtained in the United States, especially those awarding punitive damages, may not be enforceable in foreign countries.

As overseas investment funds, the investors are also subject to United States and foreign laws regulating the international flow of currency over which we have no control and which could affect the availability of the funds. Any delay in our ability to receive funds under the Recent Financings when expected could prevent us from receiving necessary capital and place us in significant financial jeopardy.

Risks Related to the Market for our Common Stock

We Have Been Removed From the Nasdaq SmallCap Market and We Are Uncertain How Trading on the Over the Counter Bulletin Board Will Affect the Liquidity and Share Value of Our Stock.

On July 13, 2001 our stock was removed from trading on the Nasdaq SmallCap Market as a result of the failure to comply with the Nasdaq Stock Market rules that required the minimum bid price for our Common Stock to exceed $1.00 per share and that we meet at least one of the following criteria:

•

have net tangible assets equal at least $2.0 million;

•

have market capitalization is equal to $35.0 million in public float; or

•

recognize net income of at least $500,000 in our most recent fiscal year or in two of our three previous fiscal years.

Beginning on July 13, 2001, our stock has traded on the Over-the-Counter Bulletin Board. Although the per share price of our Common Stock has declined since it was delisted from the Nasdaq SmallCap Market, trading volume in our stock has remained fairly constant. We are uncertain, however, about the long-term impact, if any, on trading volume and share value as a result of trading on the Over-the-Counter Bulletin Board.

The Price of Our Common Stock Has Been Highly Volatile Due to Several Factors Which Will Continue to Affect the Price of Our Stock.

Our Common Stock has traded as low as $0.09 per share and as high as $1.47 per share in the twelve months ended December 31, 2001. Some of the factors leading to the volatility include:

•

price and volume fluctuations in the stock market at large which do not relate to our operating performance;

•

fluctuations in our operating results;

•

introductions of alternative means for testing for HIV by competitors.introductions of alternative means for testing for HIV by competitors.concerns about our ability to finance our continuing operations;

•

financing arrangements, including the Recent Financings, and other financings we may enter which require the issuance of a significant number of shares in relation to the number of shares currently outstanding;

•

announcements of technological innovations or new products which we or our competitors make;

•

FDA and international regulatory actions;

•

availability of reimbursement for use of our products from private health insurers, governmental health administration authorities and other third-party payors;

•

developments with respect to patents or proprietary rights;

•

public concern as to the safety of products that we or others develop;

•

changes in health care policy in the United States or abroad;

•

changes in stock market analysts’ recommendations regarding Calypte, other medical products companies or the medical product industry generally, and

•

fluctuations in market demand for and supply of our products.

An Investor’s Ability to Trade Our Common Stock May Be Limited By Trading Volume.

The trading volume in our common shares has been relatively limited. A consistently active trading market for our Common Stock may not continue on the Over the Counter Bulletin Board. The average daily trading volume in our Common Stock on the Over the Counter Bulletin Board from the start of trading on July 13, 2001 through December 31, 2001 was approximately 260,000 shares. Daily volume during that period ranged from 13,200 shares to 1,065,300 shares. The average daily trading volume in our Common Stock on the Nasdaq SmallCap Market was approximately 386,000 shares for the twelve months ended July 12, 2001. Our daily volume during that period ranged from 33,800 to 22,257,600 shares.

Risks Related to our Business

Our Quarterly Results May Fluctuate Due to Certain Regulatory, Marketing and Competitive Factors Over Which We Have Little or No Control.

The factors listed below, some of which we cannot control, may cause our revenues and results of operations to fluctuate significantly:

•

actions taken by the FDA or foreign regulatory bodies relating to our products;

•

the extent to which our products and our HIV and STD testing service gain market acceptance;

•

the timing and size of distributor purchases; and

•

introductions of alternative means for testing for HIV by competitors.

We Have Limited Experience Selling and Marketing Our HIV-1 Urine-Based Screening Test .

Our urine-based products incorporate a unique method of determining the presence of HIV antibodies and we have limited experience marketing and selling them either directly or through our distributors. Calypte’s success depends upon the ability of domestic marketing efforts to penetrate expanded markets and upon alliances with third-party international distributors. There can be no assurance that:

•

our direct selling efforts will be effective;

•

we will obtain any expanded degree of market acceptance among physicians, patients or health care payors; or others in the medical or public health community which are essential for expanded market acceptance of the products;

•

our international distributors will successfully market our products; or

•

if our relationships with distributors terminate, we will be able to establish relationships with other distributors on satisfactory terms, if at all.

We have had FDA approval to market our urine HIV-1 screening and supplemental tests in the United States and have been marketing these products since July 1998. We have achieved significant market penetration within the domestic life insurance industry, however, we have not achieved significant marketing penetration in domestic public health agencies or internationally. Any disruption in our distribution, sales or marketing network could reduce our sales revenues and cause us to either cease operations or expend more resources on market penetration.

Our Distribution and Sales Network for U.S. Hospitals, Public Health and Reference Laboratory Markets Has Thus Far Failed to Yield Significant Sales and Revenues.

We entered into distribution agreements with distributors of medical products to domestic healthcare markets, including the distribution agreement announced in September 1999 with Carter Wallace Inc. and the Sentinel HIV and STD Testing Service announced in May 2000. These agreements did not yield significant sales and revenues and we terminated the agreement with Carter-Wallace effective March 31, 2001. We have expanded our own direct sales force to penetrate the domestic healthcare markets and, in conjunction with our business partners, have re-launched Sentinel. If our efforts to market our products to domestic hospitals, public health and reference laboratories fail to yield significant amounts of revenue, we may have to cease operations.

We Depend Upon the Viability of Three Primary Products – Our HIV-1 Urine-Based Screening Test and our Urine and Blood Based Supplemental Tests.

Our HIV-1 urine-based screening test and urine and blood-based supplemental tests are our only products. In addition, we have from time to time been able to make significant sales of our HIV viral lysate that we use in producing our Western Blot tests. Accordingly, we may have to cease operations if our screening and supplemental tests fail to achieve market acceptance or generate significant revenues.

We May Not be Able to Successfully Develop and Market New Products That We Plan to Introduce

We plan to develop other urine-based diagnostic products including a rapid HIV screening test and tests for other infectious diseases or health conditions. There are numerous developmental and regulatory issues that may preclude the introduction of these products into commercial sale. If we are unable to demonstrate the feasibility of these products or meet regulatory requirements with respect to their marketing, we may have to abandon them and alter our business plan. Such modifications to our business plan will likely delay achievement of milestones related to revenue increases and achievement of profitability.

Our Products Depend Upon Rights To Technology That We Have Licensed From Third Party Patent Holders and There Can Be No Assurance That the Rights We Have Under These Licensing Agreements Are Sufficient or That We Can Adequately Protect Those Rights.

We currently have the right to use patent and proprietary rights which are material to the manufacture and sale of our HIV-1 urine-based screening test under licensing agreements with New York University, Cambridge Biotech Corporation, Repligen Corporation, and the Texas A&M University System. We also have the right to use patent and proprietary rights material to the manufacture and sale of our HIV-1 serum-based supplemental test under a licensing agreement with National Institutes of Health. Also, if our financial condition reduces our ability to make royalty payments due under our license agreement, our rights to use those licenses could be jeopardized.

In addition, we have received correspondence from the National Institutes of Health alleging that our HIV-1 urine-based test products are also subject to the patent under which we license our serum-based supplemental test and requesting the payment of additional license fees of approximately $300,000 for past shipments plus a royalty on future shipment of our urine-based products. We have informed the NIH that we do not agree with their analysis of the patent in question. However, we cannot assure that we will be successful if the matter is

pursued further by NIH, or if it is litigated. If our analysis of the patent does not prevail and if we become subject to royalty payments to the NIH for past and future shipments of our urine-based test products it would reduce the funds that we have available to fund our continuing operations and might result in a decrease in our gross margin on those products and/or cause us to increase the price of those products, which could adversely affect the market share for our urine-based products.

We Rely On Sole Source Suppliers That We Cannot Quickly Replace For Certain Components Critical To The Manufacture of Our Products.

Any delay or interruption in the supply of these sole source components could have a material adverse effect on us by significantly impairing our ability to manufacture products in sufficient quantities, particularly as we increase our manufacturing activities in support of commercial sales. In addition, if our financial condition reduces our ability to pay for critical components on a timely basis, that may cause suppliers to delay or cease selling critical components to us, which could also impair our ability to manufacture.

We Have Limited Experience in Manufacturing Our Products and Little Experience in Manufacturing Our Products In Commercial Quantities.

We may encounter difficulties in scaling-up production of new products, including problems involving:

•

production yields;

•

quality control and assurance;

•

raw material supply; and

•

shortages of qualified personnel.

Any such difficulty would affect our ability to meet increases in demand should our products gain market acceptance and reduce growth in our sales revenues.

The Success of Our Plans to Enter International Markets May Be Limited or Disrupted Due to Risks Related to International Trade and Marketing and the Capabilities of Our Distributors.

We anticipate that international distributor sales will generate a significant portion of our revenues for the next several years. We believe that our urine-based test can provide significant benefits in countries that do not have the facilities or personnel to safely and effectively collect and test blood or other bodily fluid samples. The following risks may limit or disrupt our international sales;

•

the imposition of government controls;

•

export license requirements;

•

political instability;

•

trade restrictions;

•

changes in tariffs;

•

difficulties in managing international operations;

•

fluctuations in foreign currency exchanges rates;

•

the financial stability of our distributors;

•

the ability of our distributors to successfully sell into their contractual market territory or to successfully cover their entire territory; and

•

the possibility that a distributor may be unable to meet minimum contractual purchase commitments.

Some of our distributors have limited international marketing experience. There can be no assurance that these distributors will be able to successfully market our products in foreign markets. Any such failure will delay or disrupt our plans to expand the Company’s business.

We Face Intense Competition in the Medical Diagnostic Products Market and Rapid Technological Advances by Competitors.

Competition in our diagnostic market is intense and we expect it to increase. Within the United States, our competitors include a number of well-established manufacturers of HIV tests using blood samples, plus at least one system for the detection of HIV antibodies using oral fluid samples. Many of our competitors have significantly greater financial, marketing and distribution resources than we do. Our competitors may succeed in developing or marketing technologies and products that are more effective than ours. These developments could render our technologies or products obsolete or noncompetitive or otherwise affect our ability to increase or maintain our products’ market share.

Our Ability to Market Our Product Depends Upon Obtaining and Maintaining FDA and Foreign Regulatory Approvals.

Numerous governmental authorities in the United States and other countries regulate our products. The FDA regulates our products under federal statutes and regulations related to pre-clinical and clinical testing, manufacturing, labeling, distribution, sale and promotion of medical devices in the United States. In addition, our facilities are inspected periodically by the FDA with regard to the sufficiency of our manufacturing records and production procedures and we must continue to satisfy the FDA’s concerns in order to avoid regulatory action against us.

If we fail to comply with FDA regulations, or if the FDA believes that we are not in compliance with such regulations, the FDA can:

•

detain or seize our products;

•

issue a recall of our products;

•

prohibit marketing and sales of our products; and

•

assess civil and criminal penalties against us, our officers or our employees.

We also plan to sell our products in certain foreign countries where they may be subject to similar local regulatory requirements. The imposition of any of the sanctions described above could have a material adverse effect on us by delaying or reducing the growth in our sales revenue or causing us to expend more resources to penetrate our target markets. The regulatory approval process in the United States and other countries is expensive, lengthy and uncertain. We may not obtain necessary regulatory approvals or clearances in a timely manner, if at all. We may lose previously obtained approvals or clearances or fail to comply with regulatory requirements. The occurrence of any of these events would be likely to have a material adverse effect on Calypte by disrupting our marketing and sales efforts.

Our Research and Development of HIV Urine Tests Involves the Controlled Use of Hazardous Materials.

There can be no assurance that the Company’s safety procedures for handling and disposing of hazardous materials such as azide will comply with applicable regulations. In addition, we cannot eliminate the risk of accidental contamination or injury from these materials. We may be held liable for damages from such an accident and that liability could have a material adverse effect on the Company.

We May Not Be Able to Retain Our Key Executives and Research and Development Personnel.

As a small company with 66 employees, our success depends on the services of key employees in executive and research and development positions. The loss of the services of one or more of such employees could have a material adverse effect on us.

As a Small Manufacturer of Medical Diagnostic Products, We Are Exposed to Product Liability and Recall Risks For Which Insurance Coverage is Expensive, Limited and Potentially Inadequate.

We manufacture medical diagnostic products, which subjects us to risks of product liability claims or product recalls, particularly in the event of false positive or false negative reports. A product recall or a successful product liability claim or claims that exceed our insurance coverage could have a material adverse effect on us. We maintain a $10,000,000 claims made policy of product liability insurance. However, product liability insurance is expensive. In the future we may not be able to obtain coverage on acceptable terms, if at all. Moreover, our insurance coverage may not adequately protect us from liability that we incur in connection with clinical trials or sales of our products.

Our Charter Documents May Inhibit a Takeover.

Certain provisions of our Certificate of Incorporation and Bylaws could:

•

discourage potential acquisition proposals;

•

delay or prevent a change in control of Calypte;

•

diminish stockholders’ opportunities to participate in tender offers for our Common Stock, including tender offers at prices above the then current market price; or

•

inhibit increases in the market price of our Common Stock that could result from takeover attempts.

We Have Adopted a Stockholder Rights Plan That Has Certain Anti-takeover Effects.

On December 15, 1998, the Board of Directors of Calypte declared a dividend distribution of one preferred share purchase right (“Right”) for each outstanding share of Common Stock of the Company. The dividend was payable to the stockholders of record on January 5, 1999 with respect to each share of Common Stock issued thereafter until a subsequent “distribution date” defined in a Rights Agreement and, in certain circumstances, with respect to shares of Common Stock issued after the Distribution Date.

The Rights have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire the Company without conditioning the offer on the Rights being redeemed or a substantial number of Rights being acquired. However, the Rights should not interfere with any tender offer, or merger, which is approved by the Company because the Rights do not become exercisable in the event of an offer or other acquisition exempted by Calypte’s Board of Directors.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The primary objective of the Company’s investment activities is to preserve principal while at the same time maximizing the income received from investments without significantly increasing risk. Some of the securities that the Company may invest in may be subject to market risk. This means that a change in prevailing interest rates may cause the value of the investment to fluctuate. For example, if the Company purchases a security that was issued with a fixed interest rate and the prevailing interest rate later rises, the value of our investment will probably decline. To minimize this risk in the future, the Company intends to maintain its portfolio of cash equivalents and short-term investments in a variety of securities including commercial paper, money market funds and government and non-government debt securities. In general, money market funds are not subject to

market risk because the interest paid on such funds fluctuates with the prevailing interest rate. As of December 31, 2001, the Company neither had any holdings of derivative financial or commodity instruments, nor any foreign currency denominated transactions, and all of its cash and cash equivalents were in money market and checking funds.

The Company had a Promissory Note outstanding at December 31, 2001, which is carried at cost (see Note 6 to the Consolidated Financial Statements) with a fixed interest rate that is based on current market rates. Interest rate changes generally do not affect the fair value of variable rate debt instruments, but do impact future earnings and cash flows. Holding debt levels constant, a one percentage point increase in interest rates would decrease earnings and cash flows for variable rate debt by approximately $4,000.

The Company’s Series A redeemable preferred stock is carried at its redemption value which approximates fair value and it is not subject to interest rate risk.

Item 8. Financial Statements and Supplementary Data

The Company’s Consolidated Financial Statements are included on pages F-1 through F-33 of this Annual Report on Form 10-K.

The following table presents summarized historical quarterly results of operations for each of the fiscal quarters in the Company’s fiscal years ended December 31, 2001 and 2000. These quarterly results are unaudited, but, in the opinion of management, have been prepared on the same basis as the Company’s audited financial information and include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the information set forth therein. The data should be read in conjunction with the Financial Statements and related notes included on pages F-1 through F-33 of this Annual Report on Form 10-K.

The Company expects that its revenues and results of operations may fluctuate significantly from quarter to quarter and will depend on a number of factors, many of which are outside the Company’s control. These factors include actions relating to regulatory matters, the extent to which the Company’s products gain market acceptance, the timing and size of distributor purchases, introduction of alternative means for testing for HIV, competition, the timing and cost of new product introductions, and general economic conditions.

Such officers, directors and ten percent stockholders are also required by the Securities and Exchange Commission rules to furnish the Company with copies of all Section 16(a) forms that they file.

The Company believes that during fiscal year 2001, all the Reporting Persons complied with all applicable filing requirements subject to the following exceptions: Mr. Brounstein had one late filing of a report on Form 3 with respect to an option to purchase Calypte Common Stock granted prior to the time he became subject to reporting under Section 16.

Item 11. Executive Compensation

Director Compensation

The Company’s directors are reimbursed for their out-of-pocket travel expenses associated with their attendance at Board meetings. Under the Company’s 1995 Director Option Plan, non-employee directors of the Company are eligible to receive grants of options to purchase shares of Common Stock.

The Company’s Board of Directors adopted the Director Option Plan in December 1995 and the stockholders approved it in 1996. It was most recently amended at the Company’s September 2001 Annual Stockholders’ Meeting to increase the number of shares authorized for issuance under the Plan. Under the Director Option Plan, the Company has reserved 2,850,000 shares of common stock for issuance to the directors of the Company in the form of nonstatutory stock options. The Company’s Board of Directors determines the number of shares of the Company’s stock that will be granted each year to newly–elected and re-elected directors. Options may be granted under this plan to non-employee directors or directors who also serve as consultants of the Company. Each option granted under the Director Option Plan shall be exercisable at 100% of the fair market value of the Company’s common stock on the date such option was granted. Each grant under the

plan will vest monthly over the twelve month period commencing with the director’s date of election or re- election, provided that the option will become vested and fully exercisable on the date of the next annual meeting of stockholders if such meeting occurs less than one year after the date of the grant. The plan shall be in effect for a term of ten years unless sooner terminated under the Director Option Plan.

In August 2001, the Company executed a promissory note in the amount of $400,000 to LHC Corporation, the parent company of Trilobite Lakes Corporation, its largest stockholder. Trilobite Lakes Corporation (“Trilobite”). Trilobite is an affiliate of Claneil Enterprises, Inc. David Collins, the Chairman of the Board of Calypte serves on the Board of Directors of Claneil and is a member of Claneil’s Compensation Committee. Pursuant to the Common Stock Purchase Agreement dated March 2, 2000, Claudie Williams, a representative designated by Trilobite was elected to Calypte’s Board of Directors. The Calypte Board will nominate a representative selected by Trilobite for election to the Calypte Board for so long as Trilobite holds one-half of the shares it acquired through the Common Stock Purchase Agreement. The note required interest at 8.5% per annum and principal plus accrued interest was due no later than September 14, 2001. The note was secured by certain inventory and accounts receivable. In December 2001, the parties agreed to execute a new note in the amount of $411,000, representing the unpaid principal and accrued but unpaid interest on the previous note. This note bears interest at 8.5% and was due in installments of $200,000 on February 28, 2002 and $35,000 per month thereafter until paid in full, plus accrued interest. The repayment terms of the Note were renegotiated in February 2002. The Note now requires payments of $17,500 at the end of February and March 2002, increasing to $35,000 monthly thereafter unless and until the Company raises at least $2 million in external financing, not including the convertible debentures and warrants agreement entered into on February 11, 2002 and discussed more fully under “Liquidity and Capital Resources” in Item 7 of this Form 10-K. If there is a remaining balance under the Note upon the Company’s obtaining proceeds of at least $2 million of external financing, the Company is obligated to repay $200,000 on the note and should any balance on the Note remain thereafter, the Company is obligated to continue monthly payments of $35,000 until the Note is repaid in full.

INDEPENDENT AUDITORS’ REPORT

The Board of Directors

Calypte Biomedical Corporation:

We have audited the accompanying consolidated balance sheets of Calypte Biomedical Corporation and subsidiary (the Company) as of December 31, 2001 and 2000, and the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows for each of the years in the three-year period ended December 31, 2001. These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Calypte Biomedical Corporation and subsidiary as of December 31, 2001 and 2000, and the consolidated results of their operations and cash flows for each of the years in the three-year period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States of America.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and has an accumulated deficit that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

(1) The Company

Calypte Biomedical Corporation (“Calypte” or the “Company”) is a public healthcare company dedicated to the development and commercialization of urine–based diagnostic products and services for Human Immunodeficiency Virus Type 1 (HIV-1), sexually transmitted diseases and other infectious diseases. Calypte’s products include its screening enzyme immunoassay (“EIA”) and supplemental Western Blot tests, the only two FDA-approved HIV-1 antibody tests that can be used on urine samples. The Company believes that accurate, non-invasive urine–based testing methods for HIV and other infectious diseases may make important contributions to public health by helping to foster an environment in which testing may be done safely, economically, and painlessly.

Calypte commenced operations in 1989 and was incorporated as a Delaware corporation in June 1996, concurrent with the initial public offering of its stock. On June 1, 1998, the Company ceased being a development stage enterprise when it announced that the FDA approved its urine HIV-1 Western Blot test. That test is used on samples that are repeatedly reactive in the Company’s HIV-1 urine antibody screening test. The supplemental test completed the only available urine–based HIV-1 test method. Calypte is headquartered in Alameda, California and manufactures its HIV-1 screening test there. The Company also conducted screening test manufacturing operations at a facility in Berkeley, California through February 2001. The Company manufactures its urine and serum HIV-1 Western Blot and other products at its facilities in Rockville, Maryland. At December 31, 2000, both the Alameda and Rockville manufacturing facilities were FDA approved.

In December 1998, Calypte acquired from Cambridge Biotech Corporation certain assets relating to the Western Blot product line for certain infectious diseases. The acquisition included the urine and serum HIV-1 Western Blot products, as well as a supplemental test for Human T-Lymphotropic Virus (HTLV) that Calypte marketed through 2001. Calypte discontinued the production of that product in 2001 and will discontinue marketing it when current inventories are depleted.

Calypte and its distributors market its products in approximately a dozen countries worldwide. The Company’s marketing strategy is to use distributors, focused direct selling and marketing partners to penetrate targeted domestic and international markets. Calypte maintains a small direct sales force to sell its HIV-1 screening test and potential future products to laboratories serving the domestic life insurance market, and has recently expanded its direct sales force to target other selected domestic markets. International markets are addressed utilizing diagnostic product distributors. To date, in countries that have an approval process for diagnostic tests, the Company has received approval for the sale of its product in the Republic of South Africa, the People’s Republic of China, Indonesia and Malaysia. Several additional international approvals are pending, and the Company is collaborating with its distributors to obtain regulatory approval to market and promote its products in their local markets.

The Company has incurred net losses of $9.1 million, $ 12.2 million and $10.0 million in 2001, 2000, 1999, respectively. The accumulated deficit at December 31, 2001 was $88.2 million. The Company does not believe that current cash plus the proceeds from its existing equity line of credit and the convertible debentures and warrant exercises will be sufficient to meet its current operating expenses and capital requirements and it is continuing to explore financing alternatives. Refer to footnote 19 for a discussion of recent developments regarding the Company’s financing activities. The Company’s future liquidity and capital requirements will depend on numerous factors, including market acceptance of its products, regulatory actions by the FDA and other international regulatory bodies, intellectual property protection, and the ability to raise additional capital in a timely manner. Management expects to be able to raise additional capital; however, the Company may not be able to obtain additional financing on acceptable terms, or at all.

(2) Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the results of operations of the Company and its wholly owned subsidiary, Calypte, Inc., and Calypte Biomedical Company (the Company’s predecessor entity). All significant intercompany accounts and transactions have been eliminated in consolidation.

Prior to the sale of its equity interest in Pepgen Corporation (“Pepgen”) in 2001, the Company accounted for its interest under the equity method (Note 12).

Cash and Cash Equivalents

Cash equivalents consist primarily of investments in money market accounts and commercial paper with original maturities of three months or less.

Allowance for Doubtful Accounts

The Company provides an allowance for doubtful accounts on a specific identification basis when, due to passage of time or receipt of information, there is appropriate evidence of a customer’s inability to make the required payments.

Inventories

Inventories are stated at the lower of cost or market with cost determined using the first–in, first–out method.

Property and Equipment

Property and equipment is stated at cost. Machinery and equipment, furniture and fixtures, and computer equipment are depreciated using the straight–line method over the estimated useful lives of the assets, generally three to seven years. Leasehold improvements and equipment under capital leases are amortized or depreciated over the shorter of the remaining lease term or the useful life of the improvement.

Intangibles

Intangibles consist of tradenames and trademarks related to the acquisition of certain assets from Cambridge Biotech Corporation, and are carried at cost less accumulated amortization. During the fourth quarter of 2001, the Company determined that remaining value had suffered impairment and correspondingly wrote off the remaining unamortized balance of $22,000.

Fair Value of Financial Instruments

Financial assets and liabilities have carrying values which approximate their fair values for all periods presented. The carrying amounts of cash equivalents approximate fair value because of their short–term nature and because such amounts are invested in accounts earning market rates of interest. The carrying amounts of all other financial instruments, including the note payable, approximate fair value because of their short-term maturity.

Revenue Recognition

The Company recognizes revenue from product sales when all of the following have occurred:

•

we have received a binding purchase order from the customer;

•

we have delivered the product from our manufacturing facility to the common carrier specified by the customer;

•

the amount of the sale to be paid by the customer is fixed or determinable; and

•

our collection of the amount invoiced to the customer is probable.

Deferred Revenue

Deferred revenue is recorded on payments received from customers or distributors in advance of product shipment and will be recognized as revenue upon shipment of the related products or when all obligations related to the revenue are fulfilled.

Income Taxes

The Company accounts for income taxes under the Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for Income Taxes. SFAS No. 109 requires an asset and liability approach for the financial reporting of income taxes. Under SFAS No. 109, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under SFAS No. 109, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Stock-Based Compensation

Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based Compensation, establishes a fair-value method of accounting for stock options and similar equity instruments. The fair-value method requires that compensation cost be measured on the value of the award at the grant date, and recognized over the service period. SFAS No. 123 allows companies to either account for stock-based compensation to employees under the provisions of SFAS No. 123 or under the provisions of Accounting Principles Board (APB) Opinion No. 25 and its related interpretations. The Company accounts for its stock-based compensation to employees in accordance with the provisions of APB Opinion No. 25 and provides the pro forma disclosures required under SFAS No. 123.

The Company has recorded deferred compensation for the difference, if any, between the exercise price and the deemed fair market value of the common stock for financial reporting purposes of stock options granted to employees. The compensation expense related to such grants is amortized over the vesting period of the related stock options on a straight-line basis.

The Company accounts for equity instruments issued to non-employees in accordance with the provisions of SFAS No. 123 and Emerging Issues Task Force (EITF) Issue No. 96-18 Accounting for Equity Instruments that Are Issued to Other than Employees for Acquiring, or in Conjunction with Selling, Goods or Services.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Net Loss Per Share Attributable to Common Stockholders

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the year. The computation of diluted earnings per common share is similar to the computation of basic net loss per share attributable to common stockholders, except that the denominator is increased for the assumed conversion of convertible securities and the exercise of options to the extent they are dilutive using the treasury stock method. The weighted average shares used in computing basic and diluted net loss per share attributable to common stockholders were the same for the three years ended December 31, 2001, 2000 and 1999. Options and warrants for 16,378,379 shares, 4,982,462 shares and 4,453,795 shares were excluded from the computation of loss per share at December 31, 2001, 2000 and 1999, respectively, as their effect is antidilutive. The difference between net loss and net loss attributable to common stockholders relates to accrued dividends on the Company’s Mandatorily Redeemable Series A Preferred Stock discussed in Note 8.

Concentrations of Credit Risk

Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash and cash equivalents and trade accounts receivable. The Company has investment policies that limit investments to short-term, low-risk investments. Concentration of credit risk with respect to trade accounts receivable are limited due to the fact that the Company sells its products primarily to established distributors and laboratories and requires prepayment for certain orders where the relationship between the parties is not well-established.

Use of Estimates

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

Risks and Uncertainties

Calypte purchases certain raw materials and components used in manufacturing its products from a number of suppliers, but relies on single sources for certain other components. Establishment of additional or replacement suppliers for these components cannot be accomplished quickly. Any delay or interruption in the supply of these components could have a material adverse effect on the Company by significantly impairing its ability to manufacture products in sufficient quantities to meet commercial sales demand. Additionally, if our financial condition reduces our ability to pay for critical components or to make royalty payments under our license agreements, suppliers may delay or cease selling critical components to us or our rights to use license agreements could be jeopardized, both of which could also impair our ability to manufacture.

As of December 31, 2001, our net liabilities were $5.5 million. Our market capitalization at December 31, 2001 was approximately $7.2 million. We also have not recognized net income in any of our previous fiscal years.

Comprehensive Loss

The Company has no components of other comprehensive loss other than its net loss, and, accordingly, its comprehensive loss is equivalent to its net loss for all periods presented.

Segment and Geographic Information

SFAS No. 131 “Disclosures about Segments of an Enterprise and Related Information,” requires an enterprise to report segment information based on how management internally evaluates the operating performance of its business units (segments). The Company’s operations are currently confined to a single business segment: the development and sale of HIV diagnostics.

Substantially all of the Company’s sales through 2001 have been to United States customers. Sales to international customers accounted for 5% and 4% of the Company’s revenues in 2001 and 2000, respectively.

Sales to three major domestic customers amounted to approximately 57% of total net sales for the year ended December 31, 2001. Sales to those customers accounted for 25%, 19% and 13%, respectively, in 2001. Sales to significant domestic customers accounted for 18%, 13%, and 11% of revenues in 2000 and 19% and 12% of revenues in 1999.

Recent Accounting Pronouncements

In July 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” SFAS No. 143 requires liability recognition for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. The Company is required to adopt the provisions of SFAS No. 143 beginning with its fiscal year that starts January 1, 2003. The Company does not expect that adoption of SFAS No. 143 will have a material effect on its consolidated financial statements.

In August 2001, the FASB issued SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” SFAS No. 144 supersedes SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of”, in that it removes goodwill from its impairment scope and allows for different approaches in cash flow estimation. However, SFAS No. 144 retains the fundamental provisions of SFAS No. 121 for (a) recognition and measurement of long-lived assets to be held and used and (b) measurement of long-lived assets to be disposed of. SFAS No. 144 also supersedes the business segment concept in APB

Opinion No. 30, “Reporting the Results of Operations-Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions,” in that it permits presentation of a component of an entity, whether classified as held for sale or disposed of, as a discontinued operation. However, SFAS No. 144 retains the requirement of APB Opinion No. 30 to report discontinued operations separately from continuing operations. The Company is required to adopt the provision of SFAS No. 144 beginning with its fiscal year that starts January 1, 2002. The Company does not believe that adoption of SFAS 144 will have a material effect on its consolidated financial statements.

(6) Notes and Debentures Payable

In August 2001, the Company executed a promissory note in the amount of $400,000 to the parent company of its largest stockholder. The note required interest at 8.5% per annum and principal plus accrued interest was due no later than September 14, 2001. In December 2001, the parties agreed to execute a new note in the amount of $411,000, representing the unpaid principal and accrued but unpaid interest on the previous note. This note bears interest at 8.5% and is due in installments of $200,000 on February 28, 2002 and $35,000 per month thereafter until paid in full, plus accrued interest. The repayment terms of the Note were renegotiated in February 2002. (See Note 18.)

In January 2001, the Company signed an agreement to place up to $1.1 million in convertible short-term debentures. Under this arrangement, the Company issued two convertible debentures in the principal amount of $550,000 each. Each debenture had an interest rate of 6% and was issued at an original issue discount of 9.1%. The Company issued the first debenture on January 26, 2001 and the second on March 13, 2001. The Company received $925,000 in aggregate net cash proceeds from the issuance of the two debentures. Each debenture matured 90 days from the date of issue, or on April 26, 2001 and June 11, 2001, respectively. The Company was contractually obligated to use no less than 50% of the proceeds from any equity financing to repay the debentures. The Company redeemed the first debenture, plus accrued interest, prior to its contractual maturity using the proceeds from the sales of its common stock under the terms of its first equity line of credit (see Note 9). The Company also redeemed a portion of the second debenture prior to its contractual maturity. On June 12, 2001, the debentureholder converted the remaining $168,000 balance on the debenture plus accrued interest of approximately $7,000 into 1,008,525 shares of the Company’s Common Stock, in accordance with the conversion provisions of the debenture.

Under the terms of the debentures, the debentureholder could elect at any time prior to maturity to convert the balance outstanding on the debentures into shares of the Company’s common stock at a fixed price that represented a 5% discount to the average trading price of the shares for the 10 trading days preceding the issuance of each debenture. If the Company chose not to redeem the debentures prior to maturity, as in the case of the second debenture, the conversion discount to the debentureholder increased to 15% of the average low bid price for Calypte’s common stock for any three of the 22 trading days prior to the date of conversion. The Company determined that its debentures were issued with a beneficial conversion feature. The beneficial conversion feature was recognized by allocating an amount equal to the intrinsic value of that feature to additional paid-in capital. The intrinsic value was calculated at the date of issue as the difference between the conversion price of the debenture and the fair value of the Company’s common stock into which the debenture was convertible, multiplied by the number of common shares into which the debenture was convertible. Because each debenture was convertible into common stock at the option of the holder, the entire $322,000 discount resulting from the allocation of proceeds to the beneficial conversion feature was recognized as interest expense at the issuance date of the debentures during the first quarter of 2001. During the second quarter of 2001, the Company’s payments to the debentureholder reduced the debenture balance and effectively repurchased a portion of the beneficial conversion feature. In situations in which a debt instrument containing an embedded beneficial conversion feature is extinguished prior to conversion, a portion of the debt payment is allocated to the beneficial conversion feature using the intrinsic value of that conversion feature at the extinguishment date. Any residual amount is then allocated to the convertible security with the Company recognizing a gain or loss to remove the remaining liability. The extinguishments of the debentures and the repurchase of the beneficial conversion feature resulted in an extraordinary gain of $145,000 during the second quarter of 2001.

The Company issued a warrant for 200,000 shares of its common stock at an exercise price of $1.50 with the first debenture. The warrant was valued on the date of issue at $0.75 per share using the Black-Scholes

F-16

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

December 31, 2001, 2000 and 1999

option-pricing model with the following assumptions: expected dividend yield of 0.0%; risk free interest rate of 4.8%, the contractual life of 3 years, and volatility of 80%. The expense associated with the warrant was accounted for as interest expense and amortized over the term of the first debenture. The original issue discount was accounted for as interest expense and recognized using the effective interest method over the respective terms of the debentures.

On August 17, 2001, the Company modified the warrant, reducing its exercise price to $0.15 per share, and the debentureholder exercised it for the entire 200,000 shares. The Company received $28,500 in net proceeds from the exercise of the warrants. No additional interest expense was recorded as a result of the modification since the value of the modified warrant at the date of modification was below that of the original warrant.

In January 1999, the Company entered into a loan agreement with a bank to borrow up to $2.0 million at an interest rate of prime plus 1.25%. The Company’s assets secured borrowings under the loan. The agreement called for the loan to be repaid in twelve equal monthly installments of principal, plus accrued interest, beginning in August 1999. In January 2000, the loan was modified to extend the repayment term through August 2001. In May 2000, the loan was again modified to increase the then outstanding principal balance by $250,000. At December 31, 2000, the Company had $471,000 outstanding under this facility and the prime rate was 9.5%.

The loan agreement required the Company to maintain certain financial conditions and comply with certain reporting and other requirements. At times during 2000, including at December 31, 2000, the Company was not in compliance with certain of the financial covenants of the agreement. In the event of such non-compliance, the agreement required the Company to pledge cash to the bank in an amount equal to 105% of the outstanding loan balance. Upon the pledge of such cash, the Company was deemed to have cured any default arising from any non-compliance with the financial covenants of the agreement. The Company repaid the note in full in January 2001, using the cash pledged under the agreement. The accompanying Consolidated Balance Sheet as of December 31, 2000 and Statement of Cash Flows for the periods ended December 31, 2001 and 2000 reflect the $480,000 cash pledge to the bank that was required to cure the Company’s non-compliance as of December 31, 2000 and the subsequent use of the pledged funds to repay the note during 2001.

(7) Lease Commitments

Capital Leases

The Company has acquired equipment under three capital lease credit agreements that are collateralized by the related equipment. The lease agreements carry effective interest rates of approximately 18% per annum.

During 1993, the Company issued stock warrants for the purchase of 35,155 shares of the Company’s common stock at exercise prices ranging from $5.00 to $7.50 per share as partial consideration for obtaining two of the lease agreements. These warrants expire in 2003.

In 2000, the Company exercised its option to renew one of the capital leases for an additional three year term. In 2001, the Company acquired laboratory equipment under a capital lease having a four-year term and an effective interest rate of approximately 17.5% per annum.

(8) Mandatorily Redeemable Preferred Stock

At the time of its original incorporation, the Company issued both common stock and mandatorily redeemable Series A preferred stock. The Company is required to redeem all shares of mandatorily redeemable Series A preferred stock within 60 days of any fiscal year–end in which the Company attains $3,000,000 in retained earnings, and funds are legally available. Based on losses accumulated through December 31, 2001, the Company must achieve in excess of $91,000,000 in future earnings before any repayment is required. The mandatorily redeemable Series A preferred stock is nonvoting and holders of these shares are entitled to receive cumulative dividends at the rate of $1.20 per share per annum. Through December 31, 2001, cumulative preferred dividends totaling $1,456,000 have been charged to stockholders’ equity to accrete for the mandatorily redeemable Series A preferred stock redemption value with a corresponding increase in the recorded amount of the mandatorily redeemable Series A preferred stock.

In anticipation of using a portion of the proceeds from its Initial Public Offering to redeem the Series A preferred stock, the Company eliminated the Series A preferred stock from its articles of incorporation upon re–incorporation of the Company in Delaware in July 1996. However, management subsequently chose not to redeem the Series A preferred stock and as of December 31, 2001 it remains outstanding. The holders of such shares maintain the same rights as held before the re–incorporation.

(9) Stockholders’ Equity

Increase in Authorized Shares

On September 28, 2001, the Company filed a Certificate of Amendment to its Certificate of Incorporation with the Secretary of State of Delaware that increased the number of shares of authorized Common Stock from 50 million to 200 million. The Company’s stockholders approved the Certificate of Amendment at the Annual Meeting of Stockholders held on September 20, 2001. A principal purpose for authorizing the additional shares was for issuance pursuant to arrangements to finance the Company’s continuing operations.

Private Placements

The Company raised net proceeds of $3.1 million, $6.8 million, $8.3 million, and $0.3 million in private placement transactions of 3,102,500 shares, 3,398,000 shares, 4,096,000 shares, and 1,575,855 shares completed in January 1999, April 1999, April 2000, and November 2001, respectively.

In August 2001, the Company and a private investment fund signed a common stock purchase agreement for the future issuance and purchase of up to $10 million of the Company’s Common Stock over a twenty-four month period. The initial closing of the transaction occurred in October 2001. Under this arrangement, the Company, at its sole discretion, may draw down on this facility, sometimes termed an equity line, from time to time, and the investment fund is obligated to purchase shares of the Company’s Common Stock. The purchase price of the Common Stock purchased pursuant to any draw down will be equal to 88% of the daily volume weighted average price of the Company’s Common Stock on the applicable date. In conjunction with the signing of the stock purchase agreement, in October 2001, the Company issued a 7-year fully-vested warrant to the investment fund to purchase up to 4,192,286 shares of common Stock at an exercise price of $0.2743 per share. The warrant was valued on the date of issue at $0.22 per share using the Black-Scholes option-pricing model with the following assumptions: expected dividend yield of 0.0%; risk free interest rate of 4.3%, the contractual

life of 7 years, and volatility of 80%. The warrant was accounted for as a deferred offering cost and is recognized as a cost of the financing in proportion to the amount of each draw-down in relation to the $10 million nominal commitment amount. In October 2001, the Company filed a Registration Statement on Form S-2 with the Securities and Exchange Commission to register for resale 30,000,000 shares of Common Stock that it may issue in conjunction with the equity line facility and the warrant. During November and December 2001, the Company issued two draw down requests under this facility in the aggregate amount of $430,000. The Company issued 2,182,144 shares of its common stock and received aggregate net proceeds of $406,000 after deducting fees and expenses in settling these two draw downs. The Company continues to use the equity line facility to fund its operations. See Note 18.

The Company and an investor signed a Common Stock Purchase Agreement on November 2, 2000, subsequently amended on January 24, 2001 for the future issuance and purchase of the Company’s common stock. The stock purchase agreement established what is sometimes termed an equity line of credit or an equity draw down facility. The draw down facility operated generally as follows: The investor committed up to $25 million to purchase the Company’s common stock over a twelve month period. Once during each draw down pricing period, the Company could request a draw of up to $6 million, subject to a formula based on the Company’s average stock price and trading volume setting the maximum amount of a request for any given draw. The amount of money that the investor provided to the Company and the number of shares the Company issued in return for that money was settled during a 22 day trading period following the draw down request based on the formula in the stock purchase agreement. The investor received a 5% discount to the market price for the 22-day period and the Company received the settled amount of the draw down. By the end of the second quarter of 2001, the Company had received net proceeds of $2,014,000 and had issued 5,085,018 shares of its common stock. This represented all of the shares the Company had registered for sale under the draw down agreement, and the Company and the investor considered the agreement completed. As discussed in Note 6, the Company was obligated to apply no less than 50% of the net proceeds from this financing to repay the debentures.

In conjunction with this agreement, the Company issued to the investor a three-year fully-vested warrant to purchase 1,000,000 shares of the Company’s common stock at an exercise price of $1.55 per share. The warrant was valued on the date of issue at $0.73 per share using the Black-Scholes option-pricing model with the following assumptions: expected dividend yield of 0.0%; risk free interest rate of 4.8%, the contractual life of 3 years, and volatility of 80%. The warrant was accounted for as a deferred offering cost and was recognized as a cost of the financing in proportion to the amount of each draw-down in relation to the $25 million nominal commitment amount. To the extent that not all of the $25 million commitment was drawn, the remaining deferred offering cost of $672,000 was charged as interest expense in the second quarter of 2001

On July 31 and August 2, 2001, the Company modified the exercise price for 300,000 shares each of the warrant to $0.20 per share, and the warrantholder exercised it for an aggregate of 600,000 shares. The Company received $114,000 in net proceeds from the exercise of these warrants. On August 17, 2001, the Company modified the exercise price for the remaining 400,000 shares of the warrant to $0.15 per share. The warrantholder exercised the remaining balance of the warrant and the Company received net proceeds of $57,000 after deducting expenses of the transaction. No additional interest expense was recorded as a result of any of the modifications since the value of the modified warrant at the date of modification was below that of the original warrant.

Change of Control Provisions

Certain provisions of the Company’s Certificate of Incorporation and Bylaws may have the effect of preventing, discouraging or delaying any change in the control of the Company and may maintain the

incumbency of the Board of Directors and management. The authorization of undesignated preferred stock makes it possible for the Board of Directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of the Company. Additionally, in December 1998, the Company’s Board of Directors declared a dividend distribution of one preferred share purchase right (a “Right”) for each outstanding share of Common Stock of the Company. The dividend was payable to the stockholders of record on January 5, 1999. The Rights have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire the Company without conditioning the offer on the Rights being redeemed or a substantial number of Rights being acquired. However, the Rights should not interfere with any tender offer or merger approved by the Company because the Rights do not become exercisable in the event of a permitted offer or other acquisition exempted by the Board.

(10) Incentive Stock and Stock Options Plans

2000 Equity Incentive Plan

In June 2000, the Company’s Board of Directors and stockholders approved the adoption of the Company’s 2000 Equity Incentive Plan (the “2000 Incentive Plan”) to replace the Company’s 1991 Incentive Stock Plan, which expired in April 2001. A total of 4,000,000 shares of common stock were initially reserved for issuance under the 2000 Incentive Plan. The Company’s stockholders authorized an additional reserve of 13,000,000 shares at the Annual Stockholders’ Meeting in September 2001. Additionally, all of the shares reserved but not issued or subject to options granted under the Company’s 1991 Incentive Stock Plan are available for grant under the 2000 Incentive Plan. The Compensation Committee of the Company’s Board of Directors administers the Plan. The Board of Directors may amend or modify the 2000 Incentive Plan at any time. It will expire in June 2010, unless terminated earlier by the Board of Directors.

Under the terms of the 2000 Incentive Plan, nonstatutory stock options, restricted stock and stock bonuses may be granted to employees, including directors who are employees, non-employee directors, and consultants. Incentive stock options may be granted only to employees.

Nonstatutory stock options may be granted under the 2000 Incentive Plan at a price not less than 85% of the fair market value of the common stock on the date the option is granted. Incentive stock options may be granted under the 2000 Incentive Plan at a price not less than 100% of the fair market value of the common stock on the date the option is granted.

Incentive and nonstatutory stock options granted to employees or consultants who, on the date of grant, own stock representing more than 10% of the voting power of all classes of stock of the Company are granted at an exercise price not less than 110% of the fair market value of the common stock. Options granted under the 2000 Incentive Plan generally vest monthly over periods of up to three years, as specified in the option agreements. The term of nonstatutory and incentive stock options granted is 10 years or less from the date of the grant, as provided in the option agreements.

Restricted stock awards may be granted to purchase stock either in addition to, or in tandem with, other awards under the 2000 Incentive Plan, under conditions determined by the Compensation Committee. The purchase price for such awards must be no less than 85% of the fair market value of the Company’s Common Stock on the date of the grant. The Compensation Committee may also grant stock bonus awards to employees or consultants for services rendered to the Company. Such awards may also be granted either in addition to, or in tandem with, other awards under the 2000 Incentive Plan, under conditions determined by the Compensation Committee.

1995 Director Option Plan

In December 1995, the Company’s Board of Directors approved the Company’s Director Option Plan (the Director Option Plan). During 2001 and 2000, the Board of Directors and the stockholders approved an increase in the number of shares reserved for issuance under the Plan by 2,000,000 and 500,000, respectively, bringing the total number of shares of common stock reserved for issuance to the directors of the Company pursuant to nonstatutory stock options to 2,850,000. Under the Director Option Plan, the Company’s Board of Directors determines the number of shares of the Company’s stock that will be granted each year to newly-elected and re-elected directors. Options may be granted under this plan to non-employee directors or, pursuant to an agreement between the Company and another person, entity or affiliate with whom a non-employee director is associated, that other person, entity, or affiliate.

1995 Employee Stock Purchase Plan

In December 1995, the Company’s Board of Directors approved the Company’s Employee Stock Purchase Plan (the Purchase Plan). The Purchase Plan is intended to qualify under Section 423 of the Internal Revenue Code (the Code). The Company initially reserved 300,000 shares of common stock for issuance under the Purchase Plan. In 2001, the Board of Directors and stockholders authorized reserving an additional 1,000,000 shares for issuance under the Purchase Plan. Under the Purchase Plan, an eligible employee may purchase shares of common stock from the Company through payroll deductions of up to 10% of his or her compensation, at a price per share equal to 85% of the lower of (i) the fair market value of the Company’s common stock on the first day of an offering period under the Purchase Plan or (ii) the fair market value of the common stock on the last day of the six month purchase period during the offering period. Each offering period lasts for twenty–four months; stock purchases occur on April 30 and October 31 of each year. For the years ended December 31, 2001, 2000 and 1999, 135,794, 39,801, and 27,535, shares, respectively, were purchased under the Purchase Plan. Cumulative purchases under the Purchase Plan at December 31, 2001 totaled 232,479 shares, leaving 1,067,521 shares reserved for subsequent purchase.

Under SFAS No. 123, compensation cost is recognized for the fair value of the employees’ purchase rights. The following table summarizes the per share weighted-average fair value of purchase rights granted during 2001, 2000, and 1999, on the date of grant using the Black-Scholes option-pricing model with the indicated weighted-average assumptions:

Pro Forma Disclosure

Had the Company determined compensation cost based on the fair value at the grant date for its stock options and purchase rights under SFAS No. 123, the Company’s net loss would have been increased to the pro forma amounts indicated below for the years ended December 31:

	2001			2000			1999
	(in thousands)			(in thousands)			(in thousands)
Net loss attributable to common stockholders
As reported	$	(9,248	)	$	(12,364	)	$	(10,146	)

Pro forma	$	(0.34	)	$	(0.56	)		(0.57	)

Pro forma net loss reflects only options granted since 1995 as well as purchase rights granted since 1996. Therefore, the full impact of calculating compensation cost for stock options under SFAS No. 123 is not reflected in the pro forma net loss amounts presented above because compensation cost is reflected over the options’ vesting period and compensation cost for options granted prior to January 1, 1995 is not considered.

(11) Section 401(k) Plan

Effective January 1, 1995, the Company adopted a Retirement Savings and Investment Plan (the 401(k) Plan) covering the Company’s full-time employees located in the United States. The 401(k) Plan is intended to qualify under Section 401(k) of the Internal Revenue Code. Under the terms of the 401(k) Plan, employees may elect to reduce their current compensation by up to the statutorily prescribed annual limit and to have the amount of such reduction contributed to the 401(k) Plan. The Company has not made any contributions to the 401(k) Plan.

(12) Investment in Pepgen Corporation

In 1995, the Company purchased a 49% equity interest in Pepgen Corporation (“Pepgen”) for $2.5 million, comprised of $1.0 million paid at closing, a $1.0 million promissory note and options to purchase the Company’s common stock valued at $500,000. The $1.0 million promissory note balance was paid in 1996. The options were granted to Pepgen’s stockholders for the purchase of an aggregate of 475,000 shares of the Company’s common stock at a price of $7.50 per share, of which 100,000 of such shares were immediately exercisable upon signing of the agreement and the remaining 375,000 shares become exercisable upon attainment of certain milestones. The Company valued the options utilizing the Black-Scholes option-pricing model which considered the terms of the options, other market assumptions consistent with those as determined by an independent valuation appraiser, a volatility index for the biotechnology industry and certain other factors related to the probability and timing of attaining related milestones. The options expire at the earlier of September 2005 or three years after becoming exercisable. During the second quarter of 2001, the Company sold its interest in Pepgen for $500,000, citing its short-term financial requirements and strategic commitment to diagnostic, rather than therapeutic, products.

During 1998, the Company loaned Pepgen $768,000 at an interest rate of 10%. The loan was subsequently written off as research and development expense in 1999. The Company spent additional amounts totaling $63,000 on research and development related to Pepgen during 1999. In October 1999, Pepgen secured $3.8 million in a new

round of financing, reducing the Company’s equity interest to 38%. In June 2000, Pepgen secured an additional $2.0 million in another round of financing, further reducing the Company’s equity interest to 29%.

Prior to the sale of its interest in 2001, the Company’s carried its investment in Pepgen at zero, as the proportionate losses recognized by the Company had reduced the initial investment to that amount.

Company’s ability to realize its deferred tax assets, a 100% valuation allowance has been established. When realized, approximately $171,000 of deferred tax assets will be creditable to paid-in capital.

As of December 31, 2001, the Company had federal tax net operating loss carryforwards of approximately $82,099,000, which will expire in the years 2004 through 2021. The Company also has federal research and development credit carryforwards as of December 31, 2001 of approximately $1,124,000, which will expire in the years 2005 through 2021.

State tax net operating loss carryforwards were approximately $34,548,000 and state research and development credit carryforwards were $618,000 as of December 31, 2001. The state net operating loss carryforwards will expire in the years 2002 through 2011 and the state research and development credits will carryforward indefinitely.

The Company’s ability to utilize its net operating loss and research and development tax credit carryforwards may be limited in the future if it is determined that the Company experienced an ownership change, as defined in Section 382 of the Internal Revenue Code.

(14) Royalty, License, and Research Agreements

Royalty and License Agreements

The Company has entered into an agreement that provides for royalty payments to former related parties based on sales of certain products conceived by the former related parties prior to March 30, 1989.

The Company has entered into arrangements with various organizations to receive the right to utilize certain patents and proprietary rights under licensing agreements in exchange for the Company making certain royalty payments based on sales of certain products and services. The royalty obligations are based on a percentage of net sales of licensed products and include minimum annual royalty payments under some agreements. At December 31, 2001, the Company is in arrears on the payment of royalties under certain of its licensing agreements. Under certain of those arrangements, the patent holder or other organization granting rights to the Company has the right to revoke the license for non-payment of royalties.

Research Agreement

As amended in 1994, the Company entered into a research agreement that allowed for a university to perform certain research on behalf of the Company for a seven-year period. Under the terms of the agreement, the Company may negotiate certain license rights to the inventions made by the university resulting from this research. The Company’s annual payment under this agreement was approximately $150,000 through 1999. The Company made no payments attributable to this agreement in 2000 or 2001.

(15) Distribution Agreements

United States

In September 1999, the Company appointed Wampole Laboratories, a division of Carter-Wallace Inc., as the exclusive U.S. distributor of its HIV-1 urine-based screening test to all markets other than the insurance market. The agreement had an initial five-year term. Exclusivity for the full term of the agreement was

F-29

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

December 31, 2001, 2000 and 1999

predicated on the purchase of targeted volumes of the Company’s product over a two year period. The agreement was terminated as of March 31, 2001 and the Company hired its own sales force that now addresses the hospital, public health, and reference laboratory markets.

International

The Company has entered into distribution agreements with ten international distributors granting them exclusive rights to distribute the Company’s products in approximately one dozen countries. The agreements generally have terms of from one to three years. Continuing exclusivity and agreement renewal or extension is typically dependent upon specified minimum purchases following successful local regulatory approval of the product. At December 31, 2001, the product was registered for sale in the Republic of South Africa, the People’s Republic of China, Indonesia, and Malaysia. Regulatory approvals in France, the Philippines, Korea and Brazil are in process.

(16) Consulting and Employment Agreements

In January 1995, the Company entered into an employment agreement with an officer for the year ended December 31, 1995, which provided for an annual salary of $140,000 plus an annual bonus not to exceed $35,000 per year. The agreement was amended in November 1999 to provide payment of the officer’s base salary through April 2000. The agreement was subsequently amended in 2000 to provide for payment of $100,000 in cash and stock for services from April 2000 through March 2001. The agreement was not extended or renewed thereafter.

In December 1997, the Company entered into a consulting agreement with a Board member effective from December 1997 to June 1998. Under the agreement, the consultant received compensation of $6,000 per month and was granted 50,000 stock options, which vested over the period of the agreement. The options were cancelled as of October 1999. A replacement grant was made in April 2000 at the same exercise price as for the original grant, which exceeded the April 2000 price. Other terms of the grant were the same as the original grant.

In December 1997, the Company entered into a consulting agreement with a Board member effective from January 1998 through June 1998. Under the agreement, the consultant received compensation of $2,500 per month and was granted 50,000 stock options, which vested over a 36 month period with the possibility of immediate vesting under certain conditions. The options were cancelled as of October 1999. A replacement grant was made in April 2000 at the same exercise price as for the original grant, which exceeded the April 2000 price. Other terms of the grant were the same as the original grant.

In October 1998, the Company entered into employment agreements with two officers. Those agreements expired upon the termination of employment and execution of Consulting Agreements that extended from 1999 to 2000 between the Company and each of the officers. Those agreements were subsequently extended in 2000 for an additional twelve-month term, after which they expired and were not renewed.

In October 1999, the Company entered into an employment agreement with an officer and director of the Company that included a base salary, subject to annual review, and the grant of 450,000 stock options, which vest over 24 months. The officer is also entitled to a bonus upon the achievement of milestones mutually agreed to by the officer and the Board of Directors. During 2000, the officer received a stock bonus of 25,000 shares of the Company’s common stock and was granted stock options that vest over 24 months to purchase an additional 300,000 shares of the Company’s stock. During 2001, the officer was granted multiple options with vesting

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

December 31, 2001, 2000 and 1999

periods ranging from 3 to 36 months to purchase an aggregate of 900,000 shares of the Company’s stock. At December 31, 2001, options to purchase 452,431 shares of stock were exercisable based on grants made during 2001. In the event the Company terminates the officer’s employment other than for cause, the officer is entitled to receive her base salary for twelve months.

In October 1999, the Company entered into a consulting agreement with a Board member to serve as an officer of the Company effective from October 1999 through October 2000. Under the terms of the agreement, the director received compensation of $5,000 per month and was granted options to purchase 150,000 shares of the Company’s stock. The options for 50,000 shares of the Company’s stock vested immediately upon execution of the Agreement, an additional 50,000 shares vested after six months, and the remaining 50,000 shares vested on the one year anniversary of the agreement. The agreement was renewed for an additional twelve months through October 2001 to compensate the Board member for service as Chairman of the Board. The director received a restricted stock award valued at $60,000 that vests over the twelve-month term of the agreement as compensation for the renewal. In 2001, the agreement was renewed for a subsequent twelve-month term. The director was granted options to purchase 300,000 shares of the Company’s stock. The options vest ratably over the twelve-month term of the agreement.

(17) Related Party Transactions

During 1997, in recognition of a Technology Rights Agreement entered into between the Company and an officer, the Company partially funded the expenses of a research foundation started by the officer. The officer entered into a loan agreement with the Company to repay such funding to the Company. The principal amount and all accrued interest was originally due on December 1, 1997, but the Company’s Board of Directors extended the due date to December 31, 1999 and then to June 12, 2000. In June 2000, the Company accepted a new note from the officer that incorporated the principal and accrued interest from the previous indebtedness. The June 2000 note was secured by the officer’s owned stock and vested stock options in the Company. The note required interest at the prime rate and was due on December 31, 2000. On September 12, 2000, the officer repaid the note and accrued interest in full.

In April 2000, the Company sold 4,096,000 shares of Common Stock to institutional investors in a private placement at $2.05 per share. The Company sold 1,951,220 of the shares to an investment company for which the Company’s Chairman of the Board serves on the Board of Directors and as a member of the Compensation Committee. Pursuant to the Common Stock Purchase Agreement dated March 2, 2000, a representative designated by the investment company was elected to and continues to serve on Calypte’s Board of Directors. The Calypte Board will nominate a representative selected by the investment company for election to the Calypte Board for so long as the investment company holds one-half of the shares it acquired through the Common Stock Purchase Agreement. In connection with the private placement, the investment company extended a $1 million line of credit to Calypte and Calypte issued a warrant for the purchase of 100,000 shares of its common stock at $3.62 per share. The line of credit converted into shares of common stock of Calypte upon the closing of the stock purchase.

As described in Note 6, in September 2001, the Company issued a $400,000 Promissory Note to the parent company of its largest stockholder.

In November 2001, the Company sold 1,575,855 shares of Common Stock under Regulation 144 to various investors in a private placement at $0.19 per share, receiving net proceeds of $295,000. The investors are required to hold the shares purchased pursuant to this offering for twelve months from the date of purchase. Three members of the Company’s Board of Directors purchased an aggregate of 721,154 shares of this offering

(18) Contingencies

The Company has received correspondence from the National Institutes of Health (“NIH”) alleging that its HIV-1 urine-based test products are also subject to the patent under which it licenses its serum-based supplemental test and requesting the payment of additional license fees of approximately $300,000 for past shipments plus a royalty on future shipment of its urine-based products. At December 31, 2001, the Company has accrued, but is delinquent in making, royalty payments to NIH for its serum-based product sales. The Company has informed the NIH that it does not agree with their analysis of the patent in question. The Company cannot, however, assure that it will be successful if the matter is pursued further by NIH, or if it is litigated. If the Company’s analysis of the patent does not prevail and if it becomes subject to royalty payments to the NIH for past and future shipments of its urine-based test products, it would reduce the funds available to fund continuing operations and might result in a decrease in its gross margin on those products and/or cause it to increase the price of those products, which could adversely affect the market share for its urine-based products.

(19) Subsequent Events (Unaudited)

Contingencies

On March 6, 2002, the NIH notified the Company that it would classify Calypte’s urine EIA test as a product that is not subject to earned royalties under the terms of the Company’s license agreement. The Company’s urine Western Blot supplemental test is, however, subject to royalties under the license. This tentative agreement with the NIH will be formalized by executing an amendment to the Company’s license agreement with NIH and an agreement regarding payment of past-due royalties, and effectively resolves the contingency described in Note 18.

Private Placement of Convertible Debentures and Warrants

On February 12, 2002, the Company announced that it had signed an agreement to place up to $850,000 in two secured convertible debentures with a private investment fund in a private placement pursuant to Regulation D of the Securities Act of 1933. In conjunction with this transaction, the Company issued warrants to purchase up to 13,700,000 shares of its Common Stock. Subject to certain trading volume restrictions as defined below, the agreement obligates the fund to purchase 12,000,000 shares covered by these warrants during the twelve months following the effectiveness of a registration statement that the Company will file with the Securities and Exchange Commission to register the resale of the shares. Based on current market conditions, if the Company issues both debentures, it expects that its aggregate net proceeds from the debentures and the mandatory exercise of the warrants will amount to approximately $2.1 million.

Under this arrangement, the Company will issue two secured convertible debentures to the investment fund with a principal amount of $425,000 each at a 12% interest rate. The Company issued the first debenture on February 12, 2002 and received $367,000 in proceeds after deducting expenses of the transaction. The Company plans to issue the second debenture when the registration statement is declared effective by the SEC. The Company expects to file the registration statement during March 2002. Each debenture will mature two years from the date of issue. Under the terms of the debentures, the investment fund can elect at any time prior to maturity to convert the balance outstanding on the debentures into shares of the Company’s common stock. Once the registration statement is declared effective, the investment fund is required to convert the debentures and to exercise the warrants each month at a rate equal to a minimum of 5% and 7.5% respectively of the trading volume in Calypte shares for the preceding 60 days. The exercise price of the warrants and the conversion price of the debentures are at floating prices that represent a discount to the trading price of the Company’s shares for the 20 trading days preceding the exercise and conversion.

On February 21, 2002, the Company renegotiated the terms of repayment under its Promissory Note with the parent company of its largest stockholder. The Note now requires payments of $17,500 at the end of February and March 2002, increasing to $35,000 monthly thereafter unless and until the Company raises at least $2 million in external financing, not including the convertible debentures and warrants discussed above. If there is a remaining balance under the Note upon the Company’s obtaining proceeds of at least $2 million of external financing, the Company is obligated to repay $200,000 on the note and should any balance on the Note remain thereafter, the Company is obligated to continue monthly payments of $35,000 until the Note is repaid in full. The Company made the required $17,500 payment on February 28, 2002.

Restructure of Trade Debt

On January 21, 2002, the Company’s Board of Directors reserved 1.6 million shares of it common stock for issuance to a number of its trade creditors. On March 4, 2002, the Company issued approximately 1.4 million of these shares to a number of those creditors, including the landlord for its Alameda manufacturing facility and one of the universities from which it licenses its patent rights. These creditors have agreed to accept the Company’s stock in satisfaction of indebtedness totaling approximately $1.6 million at December 31, 2001 plus certain patent rights for 2002.
