    Overview
 
    Ciphergen is dedicated to the discovery, development and
    commercialization of specialty diagnostic tests that provide
    physicians with information with which to manage their
    patients care and that improve patient outcomes. We intend
    to do this using translational proteomics, which is the process
    of answering clinical questions by utilizing advanced protein
    separation tools to identify and resolve variants of specific
    biomarkers, developing assays, and commercializing tests.
 
    Through collaborations with leading academic and research
    institutions, including The Johns Hopkins School of Medicine,
    The University of Texas M. D. Anderson Cancer Center, University
    College London, The University of Texas Medical Branch, The
    Katholieke Universiteit Leuven, Ohio State University Research
    Foundation, and Stanford University, we plan to develop
    diagnostic tests in the fields of hematology/oncology,
    cardiovascular disease, and womens health. The clinical
    questions we are addressing include early disease detection,
    treatment
    
    1
 
    response, monitoring of disease progression, prognosis and
    others. In July 2005, we entered into a strategic alliance
    agreement with Quest Diagnostics covering a three year period
    during which the parties have agreed to develop and
    commercialize up to three diagnostic tests based on Surface
    Enhanced Laser Desorption/Ionization, or SELDI, technology.
 
    Our most advanced programs are in the field of ovarian cancer.
    Commonly known as the silent killer, ovarian cancer
    leads to approximately 15,000 deaths each year in the United
    States. Approximately 23,000 new cases are diagnosed each year,
    with the majority in patients with late stage disease, where the
    cancer has spread beyond the ovary. Unfortunately, the prognosis
    is poor in these patients, leading to the high mortality from
    this disease. We believe that one unmet clinical need is a
    diagnostic test that can provide adequate predictive value to
    stratify patients with a pelvic mass into those with a high risk
    of invasive ovarian cancer versus those with a low risk. We
    believe that there are at least 5 million testing
    opportunities each year addressing this need. Ciphergen has
    developed a panel of biomarkers we believe provides risk
    stratification information for ovarian cancer based on a series
    of studies involving over 2,500 clinical samples from more than
    five sites.
 
    In a cohort study we were able to show, in 525 consecutively
    sampled women, a significant increase in the positive predictive
    value using our marker panel over the baseline level. This
    translates into the potential to enrich the concentration of
    ovarian cancer cases referred to the gynecologic oncologist by
    more than two-fold. Ciphergen is currently working with Quest
    Diagnostics in their efforts to commercialize this marker set.
    In addition, Ciphergen is undertaking a prospective clinical
    trial to support submission to the Food and Drug Administration,
    or FDA, for approval as an in vitro diagnostic test
    kit.
 
    Ciphergen Biosystems, Inc. was originally incorporated in
    California on December 9, 1993 under the name Abiotic
    Systems. In March 1995, we changed our corporate name to
    Ciphergen Biosystems, Inc and in May 2000, we reincorporated in
    Delaware. We had our initial public offering in September 2000.
    Recently, in November 2006 we sold certain assets and
    liabilities of our protein research tools and collaborative
    services business, or our instrument business to Bio-Rad
    Laboratories, Inc. in an asset sale transaction in order to
    concentrate our resources on developing clinical protein
    biomarker diagnostic products and services. As a result of the
    asset sale to Bio-Rad, we have substantially reduced the size of
    our staff.
 
    The
    Diagnostics Market Opportunity
 
    The economics of health care demand improved allocation of
    resources. Improved allocation of resources can be derived
    through disease prevention, early detection of disease leading
    to early intervention, and from diagnostic tools that can triage
    patients to more appropriate therapy and intervention. According
    to the Jain PharmaBiotech report, the worldwide market for
    in vitro diagnostics in 2006 was approximately
    $49.2 billion.
 
    We have chosen to focus primarily in the areas of
    hematology/oncology, cardiovascular disease, and womens
    health. Demographic trends suggest that, as the population ages,
    the burden from these diseases will increase, and the demand for
    quality diagnostic, prognostic, and predictive tests will
    increase. In addition, these areas generally lack quality
    diagnostic tests and therefore we believe patient outcomes can
    be significantly improved by the development of novel diagnostic
    and risk stratification tests.
 
    Our focus on proteomics enables us to address the market for
    diagnostic tests that simultaneously measure multiple protein
    biomarkers. A protein biomarker is a protein or protein variant
    that is present in a greater or lesser amount in a disease state
    versus a normal condition. Conventional proteomic tests measure
    a single protein biomarker whereas most diseases are complex. We
    believe that efforts to diagnose cancer and other complex
    diseases have failed in large part because the disease is
    heterogeneous at the causative level (i.e., most diseases can be
    traced to multiple potential etiologies) and at the human
    response level (i.e. each individual afflicted with a given
    disease can respond to that ailment in a specific manner).
    Consequently, measuring a single protein biomarker when multiple
    protein biomarkers may be altered in a complex disease is
    unlikely to provide meaningful information about the disease
    state. We believe that our approach, using mass spectrometry,
    will allow us to create diagnostic tests with sufficient
    sensitivity and specificity to aid the physician considering
    treatment options for patients with complex diseases.

    Scientific
    Background
 
    Genes are the hereditary coding system of living organisms.
    Genes encode proteins that are responsible for cellular
    functions. The study of genes and their functions has led to the
    discovery of new targets for drug development. Industry sources
    estimate that within the human genome there are approximately
    30,000 genes. The initial structure of a protein is determined
    by a single gene. The final structure of a protein is frequently
    altered by interactions with additional genes or proteins. These
    subsequent modifications result in hundreds of thousands of
    different proteins. In addition, proteins may interact with one
    another to form complex structures that are ultimately
    responsible for cellular functions.
 
    Genomics allows researchers to establish the relationship
    between gene activity and disease. However, many diseases are
    manifested not at the genetic level, but at the protein level.
    The complete structure of modified proteins cannot be determined
    by reference to the encoding gene alone. Thus, while genomics
    provides some information about diseases, it does not provide a
    full understanding of disease processes. We are focused on
    converting recent advances in proteomics into clinically useful
    translational proteomic diagnostic tests.
 
    The
    Relationship Between Proteins and Diseases
 
    The entire genetic content of any organism, known as its genome,
    is encoded in strands of deoxyribonucleic acid, or DNA. Cells
    perform their normal biological functions through the genetic
    instructions encoded in their DNA, which results in the
    production of proteins. The process of producing proteins from
    DNA is known as gene expression or protein expression.
    Differences in living organisms result from variability in their
    genomes, which can affect the types of genes expressed and the
    levels of gene expression. Each cell of an organism expresses
    only approximately 10% to 20% of the genome. The type of cell
    determines which genes are expressed and the amount of a
    particular protein produced. For example, liver cells produce
    different proteins from those produced by cells found in the
    heart, lungs, skin, etc. Proteins play a crucial role in
    virtually all biological processes, including transportation and
    storage of energy, immune protection, generation and
    transmission of nerve impulses and control of growth.
 
    Diseases may be caused by a mutation of a gene that alters a
    protein directly or indirectly, or alters the level of protein
    expression. These alterations interrupt the normal balance of
    proteins and create disease symptoms. A protein biomarker is a
    protein or protein variant that is present in a greater or
    lesser amount in a disease state versus a normal condition. By
    studying changes in protein biomarkers, researchers may identify
    diseases prior to the appearance of physical symptoms.
    Historically, researchers discovered protein biomarkers as a
    byproduct of basic biological disease research. This has
    resulted in the validation by researchers of approximately 200
    protein biomarkers that are being used in commercially available
    clinical diagnostic products.
 
    Limitations
    of Existing Diagnostic Approaches and Ciphergens
    Solution
 
    The in vitro diagnostics industry manufactures and
    distributes products that are used to detect thousands of
    individual components present in human derived specimens.
    However, the vast majority of these assays are used specifically
    to identify single protein biomarkers. The development of new
    diagnostic products has been limited by the complexity of
    disease states, which may be caused or characterized by several
    or many proteins or post-translationally modified protein
    variants. Diagnostic assays that are limited to the detection of
    a single protein often have limitations in clinical specificity
    (true negatives) and sensitivity (true positives) due to the
    complex nature of many diseases and the inherent biological
    diversity among populations of people. Diagnostic products that
    are limited to the detection of a single protein may lack the
    ability to detect more complex diseases, and thus produce
    results that are unacceptable for practical use.
 
    The heterogeneity of disease and of the human response to
    disease often underlies the shortcoming of single markers to
    diagnose and predict many diseases accurately. Our studies,
    particularly in ovarian cancer, have given us a better
    understanding of both the disease pathophysiology and the host
    response. By using multiple markers, we are better able to
    encompass the disease and host response heterogeneity. In
    addition, by examining specific analytes with greater
    resolution, for example, post-translational modifications, we
    believe we can improve the specificity of our diagnostic markers
    because these modifications reflect both the pathophysiology and
    host response This is accomplished using an advanced protein
    separation system (integrated equipment, reagents and software)
    to identify combinations of specific biomarkers leading to
    commercialization of disease specific assays.

    Ciphergen is applying translational proteomics research and
    development tools and methods to analyze biological information
    in an attempt to discover associations between proteins, protein
    variants, protein-protein interaction and diseases. Ciphergen
    intends to develop new diagnostic tests based on known and
    newly-identified protein markers to help physicians predict an
    individuals predisposition for a disease in order to
    better characterize, monitor progression of, and select
    appropriate therapy for such disease. Our goals are to:

    Addressing
    the heterogeneity of disease
 
    Ciphergens strategy is to create a paradigm of diagnostics
    that is based on risk stratification, multiple-marker testing,
    and information integration. This strategy is based on the
    belief that any specific disease is heterogeneous and therefore
    relying on a single disease marker to provide a simple
    yes-no answer is likely to fail. We believe that
    efforts to diagnose cancer and other complex diseases have
    failed in large part because the disease is heterogeneous at the
    causative level, meaning that most diseases can be traced to
    multiple potential etiologies, and at the human response level,
    meaning that each individual afflicted with a given disease can
    respond to that ailment in a specific manner. A better
    understanding of heterogeneity of disease and human response is
    necessary for improved diagnosis and treatment of many diseases.
 
    Validation
    of markers through proper study design
 
    Analysis of peer-reviewed publications reveals almost daily
    reports of novel biomarkers or biomarker combinations associated
    with specific diseases. Few of these are used clinically. As
    with drug discovery, preliminary research results fail to
    canvass sufficient variation in study populations or laboratory
    practices and, therefore, the vast majority of candidate
    biomarkers fail to be substantiated in subsequent studies.
    Recognizing that validation is the point at which most
    biomarkers fail, Ciphergens strategy is to reduce the
    attrition rate between discovery and clinical implementation by
    building validation into the discovery process. Biomarkers fail
    to validate for a number of reasons, which can be broadly
    classified into pre-analytical and analytical factors.
    Pre-analytical factors include study design that does not mimic
    actual clinical practice, inclusion of the wrong types of
    control individuals, and demographic bias (usually seen in
    studies in which samples are collected from a single
    institution). Analytical factors include poor control over
    laboratory protocols, inadequate randomization of study samples,
    and instrumentation biases (for example, higher signal early in
    the experimental run compared to later in the experimental run).
    Finally, the manner in which the data are analyzed can have a
    profound impact on the reliability of the statistical
    conclusions.
 
    When designing clinical studies, Ciphergen begins with the
    clinical question, since this drives the downstream clinical
    utility of the biomarkers. With this as a starting point,
    Ciphergen is able to design a study that includes the
    appropriate cases and control groups. Ciphergen further
    incorporates an initial validation component even within the
    discovery component. Ciphergen places an emphasis on
    multi-institutional studies, inclusion of clinically relevant
    controls, using qualified and trained operators to run assays
    and collect data. For example, in the 2004 Cancer Research
    paper describing the first three markers in the ovarian
    cancer panel, more than 600 specimen
    
    4
 
    samples taken from five hospitals were analyzed. The samples
    were divided into sets for training and validation purposes.
    Each site was shipped the same sample set for operator training
    and proficiency development followed by shipments of the same
    sample set for validation. The validation sample sets were
    received and tested in separate test rounds. The first round of
    validation samples is followed by a second round of independent
    validation samples. Subsequently, Ciphergen has analyzed more
    than 2,000 samples from five additional medical centers.
    Ciphergen has examined over 300 samples in its breast cancer
    program and over 400 samples in its prostate cancer program. In
    analyzing the complex proteomics data, Ciphergen takes an
    agnostic view of statistical methodologies, choosing to use a
    variety of approaches and looking for concordance between
    approaches, taking the view that markers deemed significant by
    multiple statistical algorithms are more likely to reflect
    biological conditions. rather than mathematical artifacts.
 
    Exploiting
    the power of mass spectrometry to improve assay
    specificity
 
    An important characteristic of proteins is that their functional
    activity is often modulated by changes in their structure.
    Conventional approaches to assay proteins have variable ability
    to detect these changes, and may depend on the specificity of
    the antibody to the original or altered forms of the proteins.
    Additionally, a conventional assay may inadvertently measure
    only one form of a protein while many exist. Ciphergen has
    developed programs for biomarkers in which mass spectrometry
    provides an advantage over traditional assays in characterizing
    and quantitating disease markers. Mass spectrometrys
    advantages over traditional assay approaches in these instances
    is a result of its ability to distinguish two or more highly
    related protein species based on molecular mass, or in
    combination with chromatographic separation tools, such as with
    ProteinChip®
    arrays, based on biochemical properties. Because most
    traditional assay approaches rely strictly on using antibodies
    to capture the intended analyte, protein forms with a common
    epitope are not readily distinguished. A few exemplar proteins
    that are candidates for assay development using a mass
    spectromic approach include von Willebrands factor, human
    chorionic gonadotropin, albumin, c-reactive protein, and serum
    amyloid A. One disease that Ciphergen is specifically addressing
    is TTP, a hematologic disease that affects mostly women and is a
    result of a deficiency in the enzyme ADAMTS13. Current assays
    rely on unwieldy Western Blots, which are both low throughput
    and poorly quantitative. Ciphergens assay measures
    directly the product of the enzymatic reaction for ADAMTS13, and
    provides the level of quantitation necessary to distinguish TTP
    from other thrombocytopenic diseases, evaluate patient responses
    to therapy and monitor patients during clinical remission to
    prevent recurrences of the disease.
 
    Creating
    and maintaining a multi-disease product pipeline
 
    Ciphergen plans to develop potential tests based on biomarkers
    discovered in its sponsored programs with academic
    collaborators, and also has the opportunity to in-license tests
    from an installed base of hundreds of academic SELDI customers.
    Ciphergens past strategy of selling its SELDI proteomics
    platform to researchers in academia, pharmaceutical companies,
    and biotechnology companies has provided Ciphergen with access
    to biomarkers that may potentially lead to additional diagnostic
    tests. Going forward, Bio-Rad and Ciphergen have agreed to
    continue to identify SELDI users who may provide additional
    biomarker discoveries for Ciphergens diagnostics pipeline.
    In addition, Ciphergen has the opportunity to identify
    additional markers discovered on other platforms that complement
    its existing product pipeline.
 
    Ciphergen has entered into collaboration, research, and material
    transfer agreements with more than 16 companies and
    academic institutions to support its large-scale clinical
    studies, including ongoing studies as well as studies Ciphergen
    plans to conduct in the future. Some of Ciphergens major
    collaborations in the areas of cancer and womens health
    are described in greater detail here.

    technology. TTP is a blood disorder characterized by low
    platelets, low red blood cell count (caused by premature
    breakdown of the cells), abnormalities in kidney function, and
    nervous system abnormalities. It is usually caused by a decrease
    in the function of an enzyme called ADAMTS13. Under the terms of
    the research and collaboration agreement, Ciphergen will have
    exclusive rights to license discoveries made during the course
    of this collaboration. Ciphergen will fund a portion of the
    costs incurred by the University.
 
    Ciphergen, together with its collaborators, is currently
    conducting large-scale protein biomarker studies in the
    following areas: hematology/oncology, cardiovascular disease and
    womens health. Most of these studies involve the analysis
    of large numbers of samples from healthy and diseased
    individuals, or comparing patients with the disease of interest
    to those with related diseases for which clinical distinction is
    necessary. The goal of most of these studies is to identify sets
    of proteins that serve as biomarkers for a specific disease.

    Further details regarding important developments in several of
    Ciphergens large-scale studies are set forth below.
 
    Ovarian cancer.  Commonly known as the
    silent killer, ovarian cancer leads to approximately
    15,000 deaths each year in the United States. Approximately
    23,000 new cases are diagnosed each year, with the majority in
    patients with late stage disease, i.e., when the cancer has
    spread beyond the ovary. Unfortunately, the prognosis is poor in
    these patients, leading to the high mortality from this disease.
    While the diagnosis of ovarian cancer in its earliest stages has
    a profound positive impact on the likelihood of survival of the
    disease, another factor that predicts survival from ovarian
    cancer is the specialty training of the surgeon who operates on
    the patient with ovarian cancer, with patients being treated by
    the gynecologic oncologist having better outcomes than those
    treated by the general surgeon. Accordingly, an unmet clinical
    need is a diagnostic test that can provide adequate predictive
    value to stratify patients with a pelvic mass into high risk of
    invasive ovarian cancer versus those with a low risk. No blood
    7
 
    test currently exists to address properly this clinical
    question, although CA125 is commonly used. CA125, which is
    cleared by the FDA only for monitoring for recurrence of ovarian
    cancer, is absent in up to 50% of early stage ovarian cancer
    cases, and can be elevated in diseases other than ovarian
    cancer, including benign ovarian tumors and endometriosis. These
    shortcomings limit CA125s utility in distinguishing benign
    from malignant ovarian tumors or for use in detection of early
    stage ovarian cancer. Transvaginal ultrasound is another
    diagnostic modality used with patients with ovarian tumors.
    Attempts at defining specific morphological criteria that can
    aid in a benign versus malignant diagnosis have led to the
    morphology index and the risk of malignancy index, with reports
    of 40-70%
    predictive value. However, ultrasound interpretation can be
    variable and dependent on the experience of the operator. In
    August 2004, Ciphergen along with collaborators at Johns
    Hopkins, University College London, and M. D. Anderson
    Cancer Center reported the discovery of three markers that, when
    combined, provided higher diagnostic accuracy for early stage
    ovarian cancer than other markers, for example, CA125. The three
    markers that Ciphergen reported in 2004 form the basis of an
    expanded panel of biomarkers that together have been
    demonstrated to provide risk stratification information in a
    series of studies involving over 2,500 clinical samples from 5
    sites. The most recent data, presented at the annual meeting of
    the American Society of Clinical Oncology in June 2006,
    demonstrate the portability of this marker panel among different
    clinical groups, indicating its potential validity across
    various testing populations. Ciphergen and collaborators at
    Rigshospitalet (Copenhagen) also reported the results of a
    prospective clinical trial involving over 200 consecutive women
    specifically to test the performance of this marker panel in a
    realistic patient population. In a cohort study we were able to
    show, in 525 consecutively sampled women, a significant increase
    in the positive predictive value using our marker panel over the
    baseline level. Ciphergen is continuing to investigate the role
    of these markers, as well as discovering additional biomarkers,
    that may be used to identify early stage ovarian cancer.
    Ciphergen is undertaking a prospective clinical trial to support
    submission to the FDA for approval as an in vitro
    diagnostic test.
 
    Peripheral arterial disease.  This disease
    affects 12 million Americans and is under diagnosed and
    under treated. With the rising incidence of diabetes, the
    incidence of peripheral arterial disease, or PAD, is expected to
    increase concomitantly. The absence of a good blood test
    contributes to the under diagnosis of PAD. Ciphergen in
    collaboration with Stanford University has performed both an
    initial discovery study and a first validation study that has
    resulted in the identification of a novel biomarker for PAD.
    Ongoing efforts are aimed at further validating this marker in
    combination with additional cardiovascular biomarkers.
 
    Thrombotic thrombocytopenic purpura.  This
    disease affects approximately 1,000 Americans annually and is
    life threatening in the absence of appropriate treatment, which
    is usually plasmaphoresis. Under treatment can lead to increased
    mortality from the disease while over treatment wastes precious
    resources. In addition, patients with TTP need to be monitored
    for clinical response to therapy. TTP is a result of absent or
    reduced levels, also known as a defect in the activity, of the
    enzyme ADAMTS13, Mass spectrometry was used as a logical
    approach to develop an accurate and quantitative assay to
    measure this enzymatic activity. Final assay development is
    under way.
 
    Prostate cancer.  Approximately 250,000 men are
    expected to be diagnosed with prostate cancer in the United
    States each year, approximately 195,000 of whom will need to
    make critical decisions on whether or not to undergo local
    therapy, such as surgery or radiation, and on whether or not to
    have additional treatment after local therapy. There is also a
    need for a reliable test to determine the likelihood of
    progression and the likelihood of recurrence after local
    treatment. In May 2006, Ciphergen and Johns Hopkins reported the
    discovery of two biomarkers that, when combined with PSA, were
    highly predictive of likelihood of recurrence of prostate
    cancer. Two studies, one examining over 400 men with prostate
    cancer, and the other examining 50 pairs of men followed for
    5 years with prostate cancer matched for age, cancer stage,
    and other clinical parameters. These results suggest the
    potential of a test to aid in the stratification of risk of
    highly aggressive prostate cancer, independent of other clinical
    variables, reduce over treatment of prostate cancer cases not
    likely to be lethal, and shift treatment to those cases that are
    particularly likely to be lethal.
 
    Breast cancer.  Detection of early stage breast
    cancer holds the potential to improve outcomes for women with
    this disease. No blood markers currently exist that can
    accurately detect ductal carcinoma in situ, or DCIS, which is
    one of the earliest stages of breast cancer, and it is likely
    that imaging modalities such as mammography, ultrasound, and
    magnetic resonance imaging will improve detection accuracy when
    combined with blood markers or molecular imaging targets.
    Ciphergen in collaboration with Johns Hopkins has performed two
    independent studies to identify blood markers for DCIS and stage
    I breast cancer. The first study examined 169 women with
    
    8
 
    varying stages of breast cancer, benign disease, and healthy
    women, and the second study examined 176 women from a different
    medical center as independent validation. Ciphergen is currently
    performing a 350 woman multi-center validation study to confirm
    the two markers identified in the previous studies.
 
    Assisted reproductive technology.  There has
    been increased use of assisted reproductive technology, or ART,
    to facilitate pregnancies, either in women who are infertile or
    who have waited to have babies. Currently, it is difficult to
    predict which embryos will lead to viable fetuses and successful
    live births. Therefore, women may go through multiple cycles of
    induction and implantation
    and/or may
    have multiple embryos implanted. Implantation cycles are
    expensive, and multiple implantations often result in multiple
    gestations. Therefore a test that can improve the probability
    that an implanted embryo will result in a live birth will reduce
    overall costs associated with ART and may reduce the number of
    multiple gestations. SELDI-TOF-MS profiling of conditioned media
    derived from cultured embryos has revealed a series of proteins
    that may improve in discriminating between embryos that are more
    likely to successfully implant versus those that are not. These
    results are currently undergoing validation.
 
    Commercialization
 
    If we are successful at discovering biomarkers and panels of
    biomarkers that have diagnostic utility, our commercialization
    strategy includes partnering with other parties to assist in the
    development and commercialization of our initial tests. In July,
    2005, we entered into a strategic alliance agreement with Quest
    Diagnostics covering a three year period during which the
    parties have agreed to develop and commercialize up to three
    diagnostic tests based on SELDI technology. In connection with
    this strategic alliance in exchange for common stock and
    warrants to purchase additional common stock, Quest Diagnostics
    invested $15 million in Ciphergen and received a warrant to
    invest an additional $7.7 million. In addition, Quest
    Diagnostics agreed to loan Ciphergen up to $10 million
    to pay certain costs and expenses related to the strategic
    alliance. This loan is forgivable based upon the achievement of
    certain milestones related to the development of diagnostic
    tests. If the Company fails to achieve these milestones, the
    outstanding loans will become due and payable in July 2010.
 
    We expect to commercialize and sell diagnostic tests in one or
    both of two phases. The first phase, referred to as the ASR
    phase, will involve the sale of analyte specific reagents, or
    ASR, to certain customers coupled with the grant to such
    customer of a sublicense to perform the laboratory test using
    the methodology covered by the relevant license obtained from
    our collaborator(s), e.g., a test for ovarian cancer covered by
    licenses from Johns Hopkins and the M. D. Anderson Cancer
    Center. ASRs are the raw materials which we will resell or make
    ourselves and which are utilized by clinical laboratories to
    develop and perform home brew laboratory tests in
    CLIA-regulated laboratories (i.e., laboratories regulated under
    the federal Clinical Laboratory Improvement Amendments of 1988,
    or CLIA). During the second phase, or IVD phase, we plan to
    assemble and sell in vitro diagnostic, or IVD, test
    kits, which have been cleared by the FDA, to customers together
    with SELDI instruments which we expect to purchase from Bio-Rad.
 
    Under our strategic alliance agreement, Quest Diagnostics has
    the exclusive right to perform up to three ASR laboratory tests.
    Once we begin manufacturing a test kit for each of such tests,
    we expect that Quest Diagnostics will purchase FDA-cleared IVD
    test kits from Ciphergen. Quest Diagnostics will have the
    exclusive right to perform such tests and market test kits
    purchased from Ciphergen in the United States, Mexico, the
    United Kingdom and other countries, such as Brazil, where Quest
    Diagnostics operates a clinical laboratory, for up to five years
    following commercialization of each respective test, referred to
    as the exclusive period, with non-exclusive rights to
    commercialize these tests in the rest of the world, subject to a
    royalty payable to Ciphergen. Upon expiration of the exclusive
    period, Quest Diagnostics exclusive rights will become
    non-exclusive.
 
    During the ASR phase for a given test, and as long as the
    exclusive period continues, we will sell ASRs and grant rights
    to perform such tests to Quest Diagnostics and to other
    reference laboratories, hospitals and medical clinics in
    countries where Quest diagnostics does not operate a clinical
    laboratory. Once the IVD phase begins for a given test, and as
    long as the exclusive period continues for that particular test,
    we will sell test kits and instruments to Quest Diagnostics. At
    the end of the exclusive period with respect to any test kit,
    Quest Diagnostics exclusive right to perform tests using
    such test kit will become non-exclusive. In addition to
    continuing to sell test kits to Quest Diagnostics, we will then
    also sell test kits to commercial clinical laboratories in the
    United States, Mexico, the United Kingdom and other countries
    which were exclusive to Quest Diagnostics during the exclusive
    period. In
    
    9
 
    addition to working through Quest Diagnostics, Ciphergen intends
    to seek partnerships for commercialization purposes with
    traditional in vitro diagnostic companies
    and/or with
    clinical reference labs in territories where Quest Diagnostics
    does not have exclusive rights.
 
    Customers
 
    Ciphergen expects that Quest Diagnostics and future
    commercialization partners, reference laboratories, hospitals
    and medical clinics that perform diagnostic testing will be the
    primary users of future diagnostic products which we may
    develop. Pursuant to the manufacture and supply agreement with
    Bio-Rad, Bio-Rad has agreed to supply Ciphergen with SELDI
    instruments and ProteinChip arrays previously manufactured by
    us. If Bio-Rad develops new products using SELDI technology,
    Bio-Rad has agreed to supply those products to Ciphergen to sell
    to its customers. Ciphergen can also request that Bio-Rad
    develop and manufacture new products to written specifications
    and the parties will negotiate in good faith the terms of
    purchasing such products.
 
    Competition
 
    The diagnostics industry in which Ciphergen operates is
    competitive and evolving. There is intense competition among
    healthcare, biotechnology, and diagnostic companies attempting
    to discover candidates for potential new diagnostic products.
    These companies may:
 
    |  |  |  | 
    |  |  | develop new diagnostic products in advance of Ciphergen or its
    collaborators; | 
|  | 
    |  |  | develop diagnostic products which are more effective or more
    cost-effective than those developed by Ciphergen or its
    collaborators; | 
|  | 
    |  |  | obtain regulatory clearance or approval of their diagnostic
    products more rapidly than Ciphergen or its
    collaborators; or | 
|  | 
    |  |  | obtain patent protection or other intellectual property rights
    that would limit Ciphergens or its collaborators
    ability to develop and commercialize, or their customers ability
    to use, Ciphergens, or its collaborators, diagnostic
    products. | 
 
    Ciphergen competes with companies in the U.S. and abroad that
    are engaged in the development and commercialization of novel
    biomarkers that may form the basis of novel diagnostic tests.
    These companies may develop products that are competitive with
    the products offered by Ciphergen or its collaborators, such as
    analyte specific reagents or diagnostic test kits, that perform
    the same or similar purposes as Ciphergens or its
    collaborators products. Also, clinical laboratories may
    offer testing services that are competitive with the products
    sold by Ciphergen or its collaborators. For example, a clinical
    laboratory can use either reagents purchased from manufacturers
    other than Ciphergen, or use its own internally developed
    reagents, to make diagnostic tests. If clinical laboratories
    make tests in this manner for a particular disease, they could
    offer testing services for that disease as an alternative to
    products sold by Ciphergen used to test for the same disease.
    The testing services offered by clinical laboratories may be
    easier to develop and market than test kits developed by
    Ciphergen or its collaborators because the testing services are
    not subject to the same clinical validation requirements that
    are applicable to FDA-cleared or approved diagnostic test kits.
    The diagnostic testing services market is estimated to be
    approximately $40 billion. A substantial portion of all
    sales of diagnostic products are made to a small number of
    clinical reference laboratories such as Quest Diagnostics and
    Laboratory Corporation of America, which together account for
    close to 20% of the testing services market. Therefore,
    Ciphergen expects to rely on clinical reference laboratories for
    a substantial portion of its sales. Ciphergens inability
    to establish or maintain one or more of these laboratories as a
    customer could adversely affect its business, financial
    condition, and operating results.
 
    Research
    and Development
 
    Ciphergens research and development efforts towards
    developing novel high-value diagnostic tests focus on two
    synergistic activities. First, Ciphergen is dedicated to
    developing new approaches to investigate the human proteome.
    Second, Ciphergen utilizes these new technologies to discover
    biomarkers that can address unmet clinical needs. A major area
    of our research and development activities center around efforts
    to discover and validate biomarkers and patterns of biomarkers
    that can be developed into diagnostic assays. We do this both
    
    10
 
    through in-house programs and through collaborations we have
    established with The Johns Hopkins School of Medicine, The
    University of Texas M. D. Anderson Cancer Center and University
    College London, among others.
 
    In applied research, we are developing new applications and
    reagents for quantitative differential protein expression
    analysis, protein interaction assays and protein
    characterization. Our efforts are particularly focused on
    discovery and quantitative analysis of low-abundance proteins
    present in complex samples such as plasma, serum and urine. We
    have demonstrated that the surface chemistries immobilized on
    ProteinChip Arrays have similar protein selectivity to those
    chemistries immobilized on higher capacity bead formats,
    facilitating the transition from discovery on arrays to small
    scale purification on beads as well as orthogonal purification.
    Using these approaches, we seek to improve the speed and
    efficiency of designing protein separation strategies at any
    scale based on the predictive information obtained using
    ProteinChip Systems. We believe these methods will accelerate
    the identification of discovered biomarkers.
 
    Ciphergens activities in research and development will
    maintain a strong focus in protein separation technologies, but
    will be intently focused on development (i.e., taking research
    tools and developing them into practical, usable tools for
    biomarker discovery and assay). Research will initially focus on
    three major tasks:
 
    |  |  |  | 
    |  |  | Provide methodologies for making bead technologies based on
    combinatorial ligand libraries for low-abundance protein
    enrichment practical for biomarker discovery | 
|  | 
    |  |  | Provide methodologies for making othorgonal chromatographic
    separation of proteomes in a simplified serial workflow
    practical for biomarker discovery | 
|  | 
    |  |  | Clinical assay development using novel proteomics technologies | 
 
    These objectives will maintain Ciphergens competitive edge
    in biomarker discovery abilities, and will be critical in our
    ability to improve on our current diagnostic tests under
    development as well as to develop and foster a pipeline of
    diagnostic tests. The new proteomic analysis tools that
    Ciphergen has developed are intended to provide Ciphergen an
    important advantage in the race to discover novel biomarkers.
    The complexity of the human proteome has hindered efforts to
    develop a comprehensive database of expressed proteins and their
    post-translational modifications. Consequently, entities that
    are able to leverage novel protein separation tools will have an
    advantage in analyzing clinical samples to identify biomarkers
    for disease. Ciphergen has focused on developing solutions to
    the problem of separating proteins to increase the number of
    proteins that can be detected and characterized while
    maintaining a level of throughput that permits running enough
    numbers of clinical samples to achieve statistical significance.
    These novel solutions are embodied in tools such as Equalizer
    Beads and multi-select and mini-select technologies. These tools
    have been applied to clinical samples that may be used to
    address diagnostic questions in hematology/oncology,
    womens health, and cardiovascular disease, as described
    above.
 
    Intellectual
    Property
 
    Our intellectual property includes a portfolio of owned,
    co-owned or licensed patents and patent applications. As of
    December 31, 2006, our patent portfolio included 9 issued
    U.S. patents, 54 pending U.S. patent applications and
    numerous pending patent applications and issued patents outside
    the U.S. These patents and patent applications are directed
    to several areas of technology important to our business,
    including the core SELDI technology, diagnostic applications,
    protein biochips, instrumentation, software and biomarkers. The
    issued patents covering the SELDI and mass spectrometry
    technologies expire at various times from 2013 to 2019. Pursuant
    to the Asset Purchase Agreement, Bio-Rad acquired certain
    proprietary rights used in the instrument business. At the close
    of the asset sale to Bio-Rad, we entered into a cross license
    agreement with Bio-Rad pursuant to which we retained the right
    to commercially exploit those proprietary rights, including
    SELDI technology, in the clinical diagnostics market. The
    clinical diagnostics market includes laboratories engaged in the
    research and development
    and/or
    manufacture of diagnostic tests using biomarkers, commercial
    clinical laboratories, hospitals and medical clinics that
    perform diagnostic tests. Ciphergen has been granted exclusive
    rights to commercialize the proprietary rights in the clinical
    diagnostics market during a five-year exclusivity period. After
    the end of the five-year period, we and Bio-Rad will share
    exclusive rights. Ciphergen and Bio-Rad each have the right to
    engage in negotiations with the other party for a license to any
    improvements in the proprietary rights created by the other
    party.
    
    11
 
 
    The rights to the core SELDI technology are derived through
    royalty-bearing sublicenses from Molecular Analytical Systems,
    Inc., or MAS. MAS holds an exclusive license to patents directed
    to the SELDI technology from the owner, Baylor College of
    Medicine. MAS granted certain rights under these patents to our
    wholly owned subsidiaries, IllumeSys Pacific, Inc. and Ciphergen
    Technologies, Inc. in 1997. We obtained further rights under the
    patents in 2003 through sublicenses and assignments executed as
    part of the settlement of a lawsuit between Ciphergen, MAS,
    LumiCyte and T. William Hutchens. Together, the sublicenses and
    assignments provide all rights to develop, make and have made,
    use, sell, import, market and otherwise exploit products and
    services covered by the patents throughout the world in all
    fields and applications, both commercial and non-commercial. The
    sub licenses carry the obligation to pay MAS a royalty equal to
    2% of SELDI-related revenues recognized between
    February 21, 2003 and the earlier of (i) May 28,
    2014, or (ii) the date on which the cumulative payments to
    MAS have reached $10,000,000. Through December 31, 2006, we
    had paid or accrued a total of approximately $2.6 million
    in such royalties. In connection with the asset sale of
    Ciphergens instrument business to
    Bio-Rad,
    Ciphergen sublicensed to Bio-Rad certain rights to the license
    rights for use outside of the clinical diagnostics field.
    Ciphergen retained exclusive rights to the license rights for
    use in the field of clinical diagnostics for a five year period,
    after which it will retain non-exclusive rights in that field.
    Bio-Rad agreed to pay the royalties due to MAS under the license
    rights, either directly to Ciphergen (to be paid to MAS) or
    directly to MAS, at its option.
 
    We hold licenses or options to license biomarkers developed
    using SELDI technology, and related intellectual property. As of
    December 31, 2006, 46 of our patent applications are
    directed to biomarker inventions and 8 are dedicated to
    diagnostic applications. These include applications in the areas
    of cancer, cardiovascular disease, infectious disease,
    neurodegenerative disease and womens health. We are
    currently negotiating an extension of the term of our
    collaboration agreement with The Johns Hopkins School of
    Medicine to patent applications directed to biomarkers for
    ovarian cancer that we intend to commercialize as an ovarian
    cancer diagnostic test. Other institutions and companies from
    which we hold options to license intellectual property related
    to biomarkers include University College London (England), The
    University of Texas M. D. Anderson Cancer Center, University of
    Kentucky, Ohio State University Research Foundation, McGill
    University (Canada), Eastern Virginia Medical School, Aaron
    Diamond AIDS Research Center, The University of Texas Medical
    Branch, Göteborg University (Sweden), University of Kuopio
    (Finland) and the Netherlands Cancer Institute (Netherlands),
    and Katholieke Universiteit Leuven (Belgium).
 
    Manufacturing
 
    Since the completion of the asset sale to Bio-Rad, Bio-Rad has
    taken over Ciphergens manufacturing operations and
    pursuant to the manufacture and supply agreement with Bio-Rad,
    Bio-Rad has agreed to manufacture and Ciphergen has agreed to
    purchase from Bio-Rad the ProteinChip Systems and ProteinChip
    Arrays (collectively referred to as the research tools products)
    required to support its diagnostics efforts. Ciphergen has an
    annual obligation to purchase approximately $1,230,000 per
    year of these research tools products under its manufacturing
    and supply agreement with Bio-Rad for three years. If Bio-Rad
    fails to supply any research tools products to Ciphergen,
    including any new research tools products developed by Bio-Rad
    for sale to its customers or any new research tools products
    Ciphergen has requested Bio-Rad to make and sell to Ciphergen,
    under certain conditions Ciphergen has the right to manufacture
    or have such research tools products manufactured by a third
    party for Ciphergens own use and sale to its customers and
    collaborators in the clinical diagnostics market, subject to
    payment of a reasonable royalty to Bio-Rad on sales of such
    research tools products. In the event that Bio-Rad is unable to
    provide the ProteinChip instruments, arrays and supplies as
    required, there is no guarantee that we will be able to find
    such a third party supplier, or that the cost of purchasing
    these items will be commercially reasonable. If we are not able
    to obtain the necessary ProteinChip instruments, arrays, and
    supplies, our ability to develop diagnostic products will be
    adversely affected.
 
    Ciphergen will be responsible for assuring through its incoming
    quality control process that the research tools products it
    purchases from Bio-Rad will comply with applicable government
    regulations. During 2005, Ciphergen enhanced its quality control
    systems in order to comply with FDA regulations; that compliance
    has been reviewed through an independent audit. Ciphergen
    believes it is prepared to fulfill its obligation to assure that
    such research tools products are in compliance with the
    FDAs Quality System Regulations, or QSRs, in 2007.

    Environmental
    Matters
 
    Medical
    Waste
 
    We are subject to licensing and regulation under federal, state
    and local laws relating to the handling and disposal of medical
    specimens and hazardous waste as well as to the safety and
    health of laboratory employees. Our laboratory facility in
    Fremont, California is operated in material compliance with
    applicable federal and state laws and regulations relating to
    disposal of all laboratory specimens. We utilize outside vendors
    for disposal of specimens. We cannot eliminate the risk of
    accidental contamination or discharge and any resultant injury
    from these materials. Federal, state and local laws and
    regulations govern the use, manufacture, storage, handling and
    disposal of these materials. We could be subject to damages in
    the event of an improper or unauthorized release of, or exposure
    of individuals to, hazardous materials. In addition, claimants
    may sue us for injury or contamination that results from our
    use, or the use by third parties, of these materials, and our
    liability may exceed our total assets. Compliance with
    environmental laws and regulations is expensive, and current or
    future environmental regulations may impair our research,
    development or production efforts.
 
    Occupational
    Safety
 
    In addition to its comprehensive regulation of safety in the
    workplace, the Federal Occupational Safety and Health
    Administration has established extensive requirements relating
    to workplace safety for healthcare employers, including clinical
    laboratories, whose workers may be exposed to blood-borne
    pathogens such as HIV and the hepatitis virus. These
    regulations, among other things, require work practice controls,
    protective clothing and equipment, training, medical
    follow-up,
    vaccinations and other measures designed to minimize exposure to
    chemicals and transmission of the blood-borne and airborne
    pathogens. Although we believe that we are currently in
    compliance in all material respects with such federal, state and
    local laws, failure to comply could subject us to denial of the
    right to conduct business, fines, criminal penalties and other
    enforcement actions.
 
    Specimen
    Transportation
 
    Regulations of the Department of Transportation, the
    International Air Transportation Agency, the Public Health
    Service and the Postal Service apply to the surface and air
    transportation of clinical laboratory specimens.
 
    Government
    Regulation
 
    General
 
    Our activities related to diagnostics products are, or have the
    potential to be, subject to regulatory oversight by the FDA
    under provisions of the Federal Food, Drug and Cosmetic Act and
    regulations there under, including regulations governing the
    development, marketing, labeling, promotion, manufacturing and
    export of our products. Failure to comply with applicable
    requirements can lead to sanctions, including withdrawal of
    products from the market, recalls, refusal to authorize
    government contracts, product seizures, civil money penalties,
    injunctions and criminal prosecution.
 
    Generally, certain categories of medical devices, a category
    that may be deemed to include potential future products based
    upon the
    ProteinChip®
    platform, may require FDA 510(k), or 510(k) de novo
    clearance or pre-market approval. Although the FDA believes
    it has jurisdiction to regulate in-house laboratory tests, or
    home brews, that have been developed and validated
    by the laboratory providing the tests, the FDA has not, to date,
    actively regulated those tests. Active ingredients
    (known as analyte specific reagents or
    ASRs) that are sold to laboratories for use in tests
    developed in house by clinical laboratories generally do not
    require FDA approval or clearance. ASRs generally do not require
    FDA clearance or pre-market approval if they are (1) sold
    to clinical laboratories certified by the government to perform
    high complexity testing, (2) manufactured in compliance
    with the FDAs QSRs, and (3) labeled in accordance
    with FDA requirements, including a statement that their
    analytical and performance characteristics have not been
    established. A similar statement would also be required on all
    advertising and promotional materials relating to ASRs, such as
    those used in certain of our proposed future tests. However, the
    regulatory environment surrounding in vitro diagnostic
    multivariate index assays, or IVDMIAs, is changing. IVDMIA
    devices, such as our ovarian cancer test, employ not only the
    data generated by ordinary ASRs
    
    13
 
    but also an algorithm used to generate a result that is used in
    the prevention or treatment of disease. The FDA issued draft
    guidance in September 2006 which states that it will regulate
    IVDMIAs as class II or III devices, depending on the
    risk they present. Class II devices are subject to 510(k)
    notification and class III devices require clinical testing
    and a PMA. However, FDA draft guidance is not the law and does
    not operate to bind either the FDA or the public. Guidances
    reflect the FDAs current thinking about a subject and the
    position it will take when dealing with that subject.
    Accordingly, the current state of the law with regard to
    regulation of ASRs, and IVDMIAs in particular, is very unclear.
    It is possible that the FDAs current policy or future
    revisions to FDA policies may have the effect of increasing the
    regulatory burden on manufacturers of these devices. The
    commercialization of our products and services could be impacted
    by being delayed, halted or prevented. We cannot be sure that
    tests based upon the ProteinChip platform, or a combination of
    reagents, will not require FDA 510(k), 510(k) de novo
    clearance or pre-market approval.
 
    Regardless of whether a medical device requires FDA approval or
    clearance, a number of other FDA requirements apply to the
    manufacturer of such a device and to those who distribute it.
    Device manufacturers must be registered and their products
    listed with the FDA, and certain adverse events, corrections and
    removals must be reported to the FDA. The FDA also regulates the
    product labeling, promotion and, in some cases, advertising of
    medical devices. Manufacturers must comply with the FDAs
    QSRs, which establish extensive requirements for design, quality
    control, validation and manufacturing. Thus, manufacturers and
    distributors must continue to spend time, money and effort to
    maintain compliance, and failure to comply can lead to
    enforcement action. The FDA periodically inspects facilities to
    ascertain compliance with these and other requirements.
 
    Diagnostic
    Kits
 
    The Food, Drug and Cosmetic Act requires that medical devices
    introduced to the U.S. market, unless exempted by
    regulation, be the subject of either a premarket notification
    clearance, known as a 510(k) or 510(k) de novo, or a
    premarket approval, known as a PMA. Some of our potential future
    clinical products may require a 510(k) or 510(k) de novo,
    others may require a PMA.
 
    With respect to devices reviewed through the 510(k) process, we
    may not market a device until an order is issued by the FDA
    finding our product to be substantially equivalent to a legally
    marketed device known as a predicate device. A 510(k) submission
    may involve the presentation of a substantial volume of data,
    including clinical data. The FDA may agree that the product is
    substantially equivalent to a predicate device and allow the
    product to be marketed in the U.S. On the other hand, the
    FDA may determine that the device is not substantially
    equivalent and require a PMA, or require further information,
    such as additional test data, including data from clinical
    studies, before it is able to make a determination regarding
    substantial equivalence. By requesting additional information,
    the FDA can further delay market introduction of our products.
 
    If the FDA indicates that a PMA is required for any of our
    potential future clinical products, the application will require
    extensive clinical studies, manufacturing information and likely
    review by a panel of experts outside the FDA. Clinical studies
    to support either a 510(k) submission or a PMA application would
    need to be conducted in accordance with FDA requirements.
    Failure to comply with FDA requirements could result in the
    FDAs refusal to accept the data or the imposition of
    regulatory sanctions. There can be no assurance that we will be
    able to meet the FDAs requirements or receive any
    necessary approval or clearance.
 
    Once granted, a 510(k) clearance or PMA approval may place
    substantial restrictions on how our device is marketed or to
    whom it may be sold. Even in the case of devices like ASRs,
    which may be exempt from 510(k) clearance or PMA approval
    requirements, the FDA may impose restrictions on marketing. Our
    potential future ASR products may be sold only to clinical
    laboratories certified under CLIA to perform high complexity
    testing. In addition to requiring approval or clearance for new
    products, the FDA may require approval or clearance prior to
    marketing products that are modifications of existing products
    or the intended uses of these products. We cannot assure that
    any necessary 510(k) clearance or PMA approval will be granted
    on a timely basis, or at all. Delays in receipt of or failure to
    receive any necessary 510(k) clearance or PMA approval, or the
    imposition of stringent restrictions on the labeling and sales
    of our products, could have a material adverse effect on us.
 
    As a medical device manufacturer, we are also required to
    register and list our products with the FDA. In addition, we are
    required to comply with the FDAs QSRs, which require that
    our devices be manufactured and
    
    14
 
    records be maintained in a prescribed manner with respect to
    manufacturing, testing and control activities. Further, we are
    required to comply with FDA requirements for labeling and
    promotion. For example, the FDA prohibits cleared or approved
    devices from being promoted for uncleared or unapproved uses. In
    addition, the medical device reporting regulation requires that
    we provide information to the FDA whenever there is evidence
    reasonably to suggest that one of our devices may have caused or
    contributed to a death or serious injury, or where a malfunction
    has occurred that would be likely to cause or contribute to a
    death or serious injury if the malfunction were to recur.
 
    Our manufacturing facilities are subject to periodic and
    unannounced inspections by the FDA and state agencies for
    compliance with QSRs. Additionally, the FDA will generally
    conduct a preapproval inspection for PMA devices. Although we
    believe we will be able to operate in compliance with the
    FDAs QSRs for ASRs, we have never been inspected by the
    FDA and cannot assure that we will be able to maintain
    compliance in the future. If the FDA believes that we are not in
    compliance with applicable laws or regulations, it can issue a
    warning letter, detain or seize our products, issue a recall
    notice, enjoin future violations and assess civil and criminal
    penalties against us. In addition, approvals or clearances could
    be withdrawn under certain circumstances. Failure to comply with
    regulatory requirements or any adverse regulatory action could
    have a material adverse effect on us.
 
    Any customers using our products for clinical use in the
    U.S. may be regulated under CLIA. CLIA is intended to
    ensure the quality and reliability of clinical laboratories in
    the U.S. by mandating specific standards in the areas of
    personnel qualifications, administration, participation in
    proficiency testing, patient test management, quality control,
    quality assurance and inspections. The regulations promulgated
    under CLIA establish three levels of diagnostic
    tests  namely, waived, moderately complex and highly
    complex  and the standards applicable to a clinical
    laboratory depend on the level of the tests it performs. We
    cannot assure you that the CLIA regulations and future
    administrative interpretations of CLIA will not have a material
    adverse impact on us by limiting the potential market for our
    potential future products.
 
    Medical device laws and regulations are also in effect in many
    of the countries in which we may do business outside the
    U.S. These range from comprehensive device approval
    requirements for some or all of our potential future medical
    device products, to requests for product data or certifications.
    The number and scope of these requirements are increasing.
    Medical device laws and regulations are also in effect in some
    states in which we do business. There can be no assurance that
    we will obtain regulatory approvals in such countries or that we
    will not incur significant costs in obtaining or maintaining
    foreign regulatory approvals. In addition, export of certain of
    our products which have not yet been cleared or approved for
    domestic commercial distribution may be subject to FDA export
    restrictions.
 
    Employees
 
    As of December 31, 2006, we had 36 full-time employees
    worldwide, including 6 in sales and marketing, 14 in research
    and development, 3 in manufacturing and 13 in administration. We
    also had an additional 15 individuals engaged as independent
    contractors. None of our employees are covered by a collective
    bargaining agreement. We believe that our relations with our
    employees are good. Ciphergens success will depend in
    large part on our ability to attract and retain skilled and
    experienced employees.

    The reader should carefully consider each of the risks and
    uncertainties we describe below, as well as all of the other
    information in this report. The risks and uncertainties we
    describe below are not the only ones we face. Additional risks
    and uncertainties which we are currently unaware of or that we
    currently believe to be immaterial could also adversely affect
    our business.
 
    We
    expect to continue to incur net losses in 2007 and 2008. If we
    are unable to significantly increase our revenues, we may never
    achieve profitability.
 
    From our inception in December 1993 through December 31,
    2006, we have generated cumulative revenue from continuing
    operations of approximately $193.3 million and have
    incurred net losses of approximately $217.9 million. We
    have experienced significant operating losses each year since
    our inception and expect these losses to continue for at least
    the next several quarters. For example, we experienced net
    losses of approximately $29.1 million in 2002,
    $36.7 million in 2003, $19.8 million in 2004,
    $35.4 million in 2005 and $22.1 million in 2006. Our
    losses have resulted principally from costs incurred in research
    and development, sales and marketing, litigation, and general
    and administrative costs associated with our operations. These
    costs have exceeded our gross profit which, to date, has been
    generated principally from product sales derived from a business
    that we have now sold. We expect to incur additional operating
    losses and these losses may be substantial. We may never achieve
    profitability. Even if we do achieve profitability, we may not
    be able to sustain or increase profitability on a quarterly or
    annual basis.
 
    We
    will need to raise additional capital in the future, and if we
    are unable to secure adequate funds on terms acceptable to us,
    we may be unable to execute our business plan.
 
    We believe that our current cash balances may not be sufficient
    to fund planned expenditures. This raises substantial doubt
    about our ability to continue as a going concern. During 2007,
    we may have to raise additional funds through the issuance of
    equity or debt securities, or a combination thereof, in the
    public or private markets in order to continue operations.
    Additional financing opportunities may not be available, or if
    available, may not be on favorable terms. The availability of
    financing opportunities will depend, in part, on market
    conditions, and the outlook for our company. Any future equity
    financing would result in substantial dilution to our
    stockholders. If we raise additional funds by issuing debt, we
    may be subject to limitations on our operations, through debt
    covenants or other restrictions. If adequate and acceptable
    financing is not available, we may have to delay development or
    commercialization of certain of our products or license to third
    parties the rights to commercialize certain of our products or
    technologies that we would otherwise seek to commercialize. We
    may also reduce our marketing, customer support or other
    resources devoted to our products. Any of these options could
    reduce our ability to successfully execute our business plan.

    We may
    not succeed in developing diagnostic products and even if we do
    succeed in developing diagnostic products, they may never
    achieve significant commercial market acceptance.
 
    Our success depends on our ability to develop and commercialize
    diagnostic products. There is considerable risk in developing
    diagnostic products based on our biomarker discovery efforts as
    potential tests may fail to validate results in larger clinical
    studies and may not achieve acceptable levels of clinical
    sensitivity and specificity. If we do succeed in developing
    diagnostic tests with acceptable performance characteristics, we
    may not succeed in achieving significant commercial market
    acceptance for those tests. Our ability to successfully
    commercialize diagnostic products that we may develop, such as
    tests, kits and devices, will depend on several factors,
    including:
 
    |  |  |  | 
    |  |  | our ability to convince the medical community of the safety and
    clinical efficacy of our products and their advantages over
    existing diagnostic products; | 
|  | 
    |  |  | our ability to further establish business relationships with
    other diagnostic companies that can assist in the
    commercialization of these products; and | 
|  | 
    |  |  | the agreement by Medicare and third-party payers to provide full
    or partial reimbursement coverage for our products, the scope
    and extent of which will affect patients willingness to
    pay for our products and will likely heavily influence
    physicians decisions to recommend our products. | 
 
    These factors present obstacles to significant commercial
    acceptance of our potential diagnostic products, which we will
    have to spend substantial time and money to overcome, if we can
    do so at all. Our inability to successfully do so would prevent
    us from generating additional revenue from diagnostic products
    and we could be unable to develop a profitable business.
 
    Our
    ability to commercialize our potential diagnostic tests is
    heavily dependent on our strategic alliance with Quest
    Diagnostics.
 
    On July 22, 2005, Ciphergen and Quest Diagnostics entered
    into a strategic alliance which will focus on commercializing up
    to three assays chosen from Ciphergens pipeline over the
    next three years. If this strategic alliance does not continue
    for its full term or if Quest Diagnostics fails to proceed to
    diligently perform its obligations as a part of the strategic
    alliance, such as independently developing, validating, and
    commercializing potential diagnostics tests, our ability to
    commercialize our potential diagnostic tests would be seriously
    harmed. Due to the current uncertainty with regard to FDA
    regulation of ASRs or for other reasons, Quest may elect to
    forgo development of ASR home brew laboratory tests
    and instead elect to wait for the development of IVD test kits,
    which would adversely affect our revenues. If we elect to
    increase our expenditures to fund diagnostic development
    programs or research programs on our own, we will need to obtain
    additional capital, which may not be available on acceptable
    terms, or at all. If we fail to develop diagnostic tests, our
    ability to expand our business would be seriously harmed.
 
    The
    commercialization of our diagnostic tests may be adversely
    impacted by changing FDA regulations.
 
    The current regulatory environment with regard to ASRs and
    IVDMIAs, such as our potential ovarian cancer diagnostic test,
    is unclear. To the extent the FDA requires that our potential
    diagnostic tests receive FDA 510(k) clearance or pre-market
    approval, our ability to develop and commercialize our potential
    diagnostic tests may be prevented or significantly delayed,
    which would adversely affect our revenues.
 
    If we
    fail to continue to develop our technologies, we may not be able
    to successfully foster adoption of our products and services or
    develop new product offerings.
 
    Our technologies are new and complex, and are subject to change
    as new discoveries are made. New discoveries and further
    progress in our field are essential if we are to foster the
    adoption of our product offerings. Development of these
    technologies remains a substantial risk to us due to various
    factors including the scientific challenges involved, our
    ability to find and collaborate with others working in our
    field, and competing technologies, which may prove more
    successful than ours. In addition, we have reduced our research
    and development headcount and expenditures, which may adversely
    affect our ability to further develop our technologies.
    
    17
 
 
    If we
    fail to maintain our rights to utilize intellectual property
    directed to diagnostic biomarkers, we may not be able to offer
    diagnostic tests using those biomarkers.
 
    One aspect of our business plan is to develop diagnostic tests
    based on certain biomarkers which we have the right to utilize
    through licenses with our academic collaborators, such as The
    Johns Hopkins School of Medicine and the University of Texas
    M.D. Anderson Cancer Center. In some cases, our collaborators
    own the entire right to the biomarkers. In other cases we co-own
    the biomarkers with our collaborator. If, for some reason, we
    lose our license to biomarkers owned entirely by our
    collaborators, we may not be able to use those biomarkers in
    diagnostic tests. If we lose our exclusive license to biomarkers
    co-owned by us and our collaborators, our collaborators may
    license their share of the intellectual property to a third
    party that may compete with us in offering the diagnostic test.
 
    If the
    United States Patent and Trademark Office significantly narrows
    or cancels the claims of United States Patent 6,734,022,
    which is presently under re-examination, we will not receive a
    $2,000,000 potential payment and may lose market exclusivity for
    certain of our potential products.
 
    Our United States Patent 6,734,022 (the 022 patent) is
    currently under re-examination in the United States Patent and
    Trademark Office. The 022 patent is directed to a
    fundamental process of SELDI that involves capturing an analyte
    from a sample on the surface of a mass spectrometry probe
    derivatized with an affinity reagent, applying matrix and
    detecting the captured analyte by laser desorption mass
    spectrometry. In March 2007, the USPTO issued a final office
    action in the re-examination, rejecting all of the claims of the
    022 patent. We believe that the claims of the 022
    patent are valid. While the office action is designated
    final we have, under the USPTO rules, as much as
    6 months to advocate for the patentability of the claimed
    invention with the patent examiners, after which we have
    recourse to appeal. We plan to respond to the final office
    action and if necessary to appeal the decision. If the USPTO
    does not issue a re-examination certificate confirming the
    patentability of all of the claims as originally issued in the
    022 patent, or claims of equivalent scope, we will not be
    entitled to receive the $2,000,000 holdback amount from Bio-Rad
    pursuant to the Asset Purchase Agreement between Ciphergen and
    Bio-Rad. Furthermore, if these claims are canceled or
    significantly narrowed in scope, we may be unable to block
    competitors from utilizing SELDI to develop diagnostic tests
    that involve detecting a single diagnostic biomarker, and our
    revenues may therefore be adversely affected.
 
    We
    have drawn funds from the $10 million secured line of
    credit provided by Quest Diagnostics. If we fail to achieve the
    loan forgiveness milestones set forth therein, we will be
    responsible for full repayment of the loan.
 
    In connection with the strategic alliance with Quest
    Diagnostics, Quest Diagnostics agreed to provide us with a
    $10 million secured line of credit, from which we had drawn
    a total of approximately $7.1 million as of
    December 31, 2006. Borrowings may be made in monthly
    increments of up to approximately $417,000 over a two year
    period, with accrued interest to be paid monthly. Funds from
    this collateralized line of credit may only be used to pay
    certain costs and expenses directly related to the strategic
    alliance, with forgiveness of the repayment obligations based
    upon our achievement of milestones related to the development,
    regulatory approval and commercialization of laboratory tests.
    Should we fail to achieve these milestones, we would be
    responsible for the repayment of the outstanding principal
    amount of any such loans on or before July 22, 2010.
 
    If a
    competitor infringes our proprietary rights, we may lose any
    competitive advantage we may have as a result of diversion of
    management time, enforcement costs and the loss of the
    exclusivity of our proprietary rights.
 
    Our success depends in part on our ability to maintain and
    enforce our proprietary rights. We rely on a combination of
    patents, trademarks, copyrights and trade secrets to protect our
    technology and brand. In addition to our licensed SELDI
    technology, we also have submitted patent applications directed
    to subsequent technological improvements and application of the
    SELDI technology, including patent applications covering
    biomarkers that may have diagnostic or therapeutic utility. Our
    patent applications may not result in additional patents being
    issued.
 
    If competitors engage in activities that infringe our
    proprietary rights, our managements focus will be diverted
    and we may incur significant costs in asserting our rights. We
    may not be successful in asserting our proprietary
    
    18
 
    rights, which could result in our patents being held invalid or
    a court holding that the competitor is not infringing, either of
    which would harm our competitive position. We cannot be sure
    that competitors will not design around our patented technology.
 
    We also rely upon the skills, knowledge and experience of our
    technical personnel. To help protect our rights, we require all
    employees and consultants to enter into confidentiality
    agreements that prohibit the disclosure of confidential
    information. These agreements may not provide adequate
    protection for our trade secrets, know-how or other proprietary
    information in the event of any unauthorized use or disclosure.
 
    If
    others successfully assert their proprietary rights against us,
    we may be precluded from making and selling our products or we
    may be required to obtain licenses to use their
    technology.
 
    Our success also depends on avoiding infringing on the
    proprietary technologies of others. If a third party were to
    assert claims that we are violating their patents, we might
    incur substantial costs defending ourselves in lawsuits against
    charges of patent infringement or other unlawful use of
    anothers proprietary technology. Any such lawsuit may not
    be decided in our favor, and if we are found liable, we may be
    subject to monetary damages or injunction against using their
    technology. We may also be required to obtain licenses under
    their patents and such licenses may not be available on
    commercially reasonable terms, if at all.
 
    If we
    or our future potential partners fail to comply with FDA
    requirements, we may not be able to market our products and
    services and may be subject to stringent penalties; further
    improvements to our manufacturing operations may be required
    that would entail additional costs.
 
    The commercialization of our products could be impacted by being
    delayed, halted or prevented by applicable FDA regulations. If
    the FDA were to view any of our actions as non-compliant, it
    could initiate enforcement action such as a warning letter and
    possible imposition of penalties. Finally, ASRs that we may
    provide will be subject to a number of FDA requirements,
    including compliance with the FDAs QSRs, which establish
    extensive regulations for quality assurance and control as well
    as manufacturing procedures. Failure to comply with these
    regulations could result in enforcement action for us or our
    potential partners. Adverse FDA action in any of these areas
    could significantly increase our expenses and limit our revenue
    and profitability. Although we are ISO 9001:2000 certified with
    respect to our manufacturing processes used for our previous
    ProteinChip products, we will need to undertake additional steps
    to maintain our operations in line with FDA QSR requirements.
    Our manufacturing facilities will be subject to periodic
    regulatory inspections by the FDA and other federal and state
    regulatory agencies. We have not yet been subject to an FDA
    inspection. We may not satisfy such regulatory requirements, and
    any such failure to do so would have an adverse effect on our
    diagnostics efforts.
 
    Because
    our business is highly dependent on key executives and
    employees, our inability to recruit and retain these people
    could hinder our business plans.
 
    We are highly dependent on our executive officers and certain
    key employees. Our product development could be delayed or
    curtailed if we lose the services of any of these people. To
    expand our research and product development efforts, we need
    people skilled in areas such as bioinformatics, biochemistry,
    and information services. Competition for qualified employees is
    intense. We will not be able to expand our business if we are
    unable to hire, train and retain a sufficient number of
    qualified employees. During 2004, 2005 and 2006, we took steps
    to reduce our headcount and our voluntary employee turnover has
    increased from historic levels.
 
    Our
    diagnostic efforts may cause us to have significant product
    liability exposure.
 
    The testing, manufacturing and marketing of medical diagnostics
    entails an inherent risk of product liability claims. Potential
    product liability claims may exceed the amount of our insurance
    coverage or may be excluded from coverage under the terms of the
    policy. Our existing insurance will have to be increased in the
    future if we are successful at introducing diagnostic products
    and this will increase our costs. In the event that we are held
    liable for a claim against which we are not indemnified or for
    damages exceeding the limits of our insurance coverage, our
    liabilities could exceed our total assets.
    
    19
 
 
    Business
    interruptions could limit our ability to operate our
    business.
 
    Our operations as well as those of the collaborators on which we
    depend are vulnerable to damage or interruption from fire,
    natural disasters, computer viruses, human error, power
    shortages, telecommunication failures, international acts of
    terror and similar events. Our primary facility is located in
    Fremont, California, where we also have laboratories. Although
    we have certain business continuity plans in place, we have not
    established a formal comprehensive disaster recovery plan, and
    our back-up
    operations and our business interruption insurance may not be
    adequate to compensate us for losses we may suffer. A
    significant business interruption could result in losses or
    damages incurred by us and require us to cease or curtail our
    operations.
 
    Legislative
    actions resulting in higher compliance costs are likely to
    adversely impact our future financial position, cash flows and
    results of operations.
 
    Compliance with changing regulation of corporate governance and
    public disclosure will result in additional expenses. Changing
    laws, regulations and standards relating to corporate governance
    and public disclosure, including the Sarbanes-Oxley Act of 2002,
    new SEC regulations and Nasdaq Global Market listing
    requirements, are resulting in increased compliance costs.
    Compliance with these evolving standards will result in
    increased general and administrative expenses and may cause a
    diversion of management time and attention from
    revenue-generating activities to compliance activities.
 
    Our
    business is subject to risks from international
    operations.
 
    We conduct business globally. Accordingly, our future results
    could be materially adversely affected by a variety of
    uncontrollable and changing factors including, among others,
    foreign currency exchange rates; regulatory, political, or
    economic conditions in a specific country or region; trade
    protection measures and other regulatory requirements; and
    natural disasters. Any or all of these factors could have a
    material adverse impact on our future international business. In
    certain countries, a few key individuals are important to our
    local success. In addition, China does not currently have a
    comprehensive and highly developed legal system, particularly
    with respect to the protection of intellectual property rights.
    As a result, enforcement of existing and future laws and
    contracts is uncertain, and the implementation and
    interpretation of such laws may be inconsistent. Such
    inconsistency could lead to piracy and degradation of our
    intellectual property protection.
 
    We are
    subject to environmental laws and potential exposure to
    environmental liabilities.
 
    We are subject to various international, federal, state and
    local environmental laws and regulations that govern our
    operations, including the handling and disposal of nonhazardous
    and hazardous wastes, the recycling and treatment of electrical
    and electronic equipment, and emissions and discharges into the
    environment. Failure to comply with such laws and regulations
    could result in costs for corrective action, penalties or the
    imposition of other liabilities. We also are subject to laws and
    regulations that impose liability and
    clean-up
    responsibility for releases of hazardous substances into the
    environment. Under certain of these laws and regulations, a
    current or previous owner or operator of property may be liable
    for the costs of remediating hazardous substances or petroleum
    products on or from its property, without regard to whether the
    owner or operator knew of, or caused, the contamination, as well
    as incur liability to third parties impacted by such
    contamination. The presence of, or failure to remediate
    properly, such substances could adversely affect the value and
    the ability to transfer or encumber such property. Based on
    currently available information, although there can be no
    assurance, we believe that such costs and liabilities have not
    had and will not have a material adverse impact on our financial
    results.
 
    Anti-takeover
    provisions in our charter, bylaws and stockholder rights plan
    and under Delaware law could make a third party acquisition of
    us difficult.
 
    Our certificate of incorporation, bylaws and stockholder rights
    plan contain provisions that could make it more difficult for a
    third party to acquire us, even if doing so might be deemed
    beneficial by our stockholders. These provisions could limit the
    price that investors might be willing to pay in the future for
    shares of our common stock. We are also subject to certain
    provisions of Delaware law that could delay, deter or prevent a
    change in control of us.
    
    20
 
 
    The rights issued pursuant to our stockholder rights plan will
    become exercisable the tenth day after a person or group
    announces acquisition of 15% or more of our common stock or
    announces commencement of a tender or exchange offer the
    consummation of which would result in ownership by the person or
    group of 15% or more of our common stock. If the rights become
    exercisable, the holders of the rights (other than the person
    acquiring 15% or more of our common stock) will be entitled to
    acquire, in exchange for the rights exercise price, shares
    of our common stock or shares of any company in which we are
    merged, with a value equal to twice the rights exercise
    price.
 
    Because
    we do not intend to pay dividends, our stockholders will benefit
    from an investment in our common stock only if it appreciates in
    value.
 
    We have never declared or paid any cash dividends on our common
    stock. We currently intend to retain our future earnings, if
    any, to finance the expansion of our business and do not expect
    to pay any cash dividends in the foreseeable future. As a
    result, the success of an investment in our common stock will
    depend entirely upon any future appreciation. There is no
    guarantee that our common stock will appreciate in value or even
    maintain the price at which our investor purchased his shares.
 
    Substantial
    leverage and debt service obligations may adversely affect our
    cash flows.
 
    As of December 31, 2006 we had $19 million of
    convertible senior notes outstanding. As a result of this
    indebtedness, we have high principal and interest payment
    obligations. The degree to which we are leveraged could, among
    other things:
 
    |  |  |  | 
    |  |  | make it difficult for us to make payments on the notes; | 
|  | 
    |  |  | make it difficult for us to obtain financing for working
    capital, acquisitions or other purposes on favorable terms, if
    at all; | 
|  | 
    |  |  | make us more vulnerable to industry downturns and competitive
    pressures; and | 
|  | 
    |  |  | limit our flexibility in planning for, or reacting to changes
    in, our business. | 
 
    Our ability to meet our debt service obligations will depend
    upon our future performance, which will be subject to financial,
    business and other factors affecting our operations, many of
    which are beyond our control.
 
    Our
    stock price has been highly volatile, and an investment in our
    stock could suffer a decline in value, adversely affecting the
    value of the notes or the shares into which those notes may be
    converted.
 
    The trading price of our common stock has been highly volatile
    and could continue to be subject to wide fluctuations in price
    in response to various factors, many of which are beyond our
    control, including:
 
    |  |  |  | 
    |  |  | failure to commercialize diagnostic tests and significantly
    increase revenue; | 
|  | 
    |  |  | actual or anticipated
    period-to-period
    fluctuations in financial results; | 
|  | 
    |  |  | failure to achieve, or changes in, financial estimates by
    securities analysts; | 
|  | 
    |  |  | announcements of new products or services or technological
    innovations by us or our competitors; | 
|  | 
    |  |  | publicity regarding actual or potential discoveries of
    biomarkers by others; | 
|  | 
    |  |  | comments or opinions by securities analysts or major
    stockholders; | 
|  | 
    |  |  | conditions or trends in the pharmaceutical, biotechnology and
    life science industries; | 
|  | 
    |  |  | announcements by us of significant acquisitions and
    divestitures, strategic partnerships, joint ventures or capital
    commitments; | 
|  | 
    |  |  | developments regarding our patents or other intellectual
    property or that of our competitors; | 
|  | 
    |  |  | litigation or threat of litigation; | 
    
    21
 
 
    |  |  |  | 
    |  |  | additions or departures of key personnel; | 
|  | 
    |  |  | sales of our common stock; | 
|  | 
    |  |  | limited daily trading volume; and | 
|  | 
    |  |  | economic and other external factors or disasters or crises. | 
 
    In addition, the stock market in general, and the Nasdaq Capital
    Market and the market for technology companies in particular,
    have experienced significant price and volume fluctuations that
    have often been unrelated or disproportionate to the operating
    performance of those companies. Further, there has been
    significant volatility in the market prices of securities of
    life science companies. These broad market and industry factors
    may seriously harm the market price of our common stock,
    regardless of our operating performance. In the past, following
    periods of volatility in the market price of a companys
    securities, securities class action litigation has often been
    instituted. A securities class action suit against us could
    result in substantial costs, potential liabilities and the
    diversion of managements attention and resources.
 
    Future
    sales of our common stock in the public market could adversely
    affect the trading price of our common stock, the value of the
    notes and our ability to raise funds in new stock
    offerings.
 
    Future sales of substantial amounts of our common stock in the
    public market, or the perception that such sales are likely to
    occur, could affect prevailing trading prices of our common
    stock and the value of the notes. As of December 31, 2006,
    we had:
 
    |  |  |  | 
    |  |  | 39,220,437 shares of common stock outstanding; | 
|  | 
    |  |  | 4,765,815 shares of common stock reserved for issuance upon
    exercise of options outstanding under our stock option plans
    with a weighted average exercise price of $3.61 per share | 
|  | 
    |  |  | in addition to the shares reserved for issuance upon the
    exercise of options referred to in the preceding bullet point,
    2,956,385 shares reserved for future issuance under our
    stock option and employee stock purchase plans; and | 
|  | 
    |  |  | Warrants outstanding for 2,400,000 shares of common stock
    at a purchase price of $3.50 for 2,200,000 warrants and $1.26
    for 200,000 warrants. | 
 
    Because the notes are convertible into common stock only at a
    specific conversion price, a decline in our common stock price
    may cause the value of the notes to decline.

    | ITEM 3. | LEGAL
    PROCEEDINGS | 
 
    On June 26, 2006, Health Discovery Corporation filed a
    lawsuit against us in the U.S. District Court for the
    Eastern District of Texas (Marshall Division), claiming that
    software used in certain of Ciphergens
    ProteinChip®
    Systems infringes on three of its United States patents. Health
    Discovery Corporation is seeking injunctive relief as well as
    unspecified compensatory and enhanced damages, reasonable
    attorneys fees, prejudgment interest and other costs. On
    August 1, 2006 Ciphergen filed an unopposed motion with the
    Court to extend the deadline for Ciphergen to answer or
    otherwise respond until September 2, 2006. Ciphergen filed
    its Answer and Counterclaim to the Complaint with the Court on
    September 1, 2006. On January 10, 2007, the court
    granted Ciphergens motion to transfer the case to the
    Northern District of California. The case is scheduled for a
    case management conference on April 27, 2007 in the
    Northern District of California. Given the early stage of this
    action, the Company cannot predict the ultimate outcome of this
    matter at this time.

    DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
    OPERATIONS | 
 
    Overview
 
    Prior to the November 13, 2006 asset sale of our instrument
    business to Bio-Rad we developed, manufactured and sold our
    ProteinChip®
    Systems, which use patented SELDI technology. These systems
    consist of a ProteinChip Reader, ProteinChip Software and
    related accessories which are used in conjunction with our
    consumable ProteinChip Arrays and ProteinChip Kits. We marketed
    and sold our products primarily to research biologists in
    pharmaceutical and biotechnology companies, and academic and
    government research laboratories. In 1997, we acquired IllumeSys
    Pacific, Inc., which holds specific rights to the SELDI
    technology for the instrument business market. Our first
    designed and manufactured system, the ProteinChip System,
    Series PBS I, was available for shipment in 1997.
    During 1999, we initiated the ProteinChip System,
    Series PBS II. In 1999, we also established a joint
    venture with Sumitomo Corporation to distribute our products in
    Japan. During 2000, we began offering research services and
    established Biomarker Discovery Center laboratories in locations
    in the the United States and Europe. In 2001, we introduced the
    ProteinChip Biomarker System, which utilizes sophisticated
    third-party software to automate pattern recognition-based
    statistical analysis methods and correlate protein expression
    patterns from clinical samples. We also began selling the
    Biomek®
    2000 Workstation, a robotic accessory which is manufactured by
    Beckman Coulter and we expanded our product offering with a
    SELDI ProteinChip interface to high-end tandem mass
    spectrometers. On July 31, 2001, Ciphergen acquired the
    BioSepra®
    process chromatography business from Invitrogen Corporation;
    this business was subsequently sold to Pall Corporation on
    November 30, 2004.
 
    On August 31, 2002, we increased our ownership interest in
    Ciphergen Biosystems KK, the Japanese joint venture we formed
    with Sumitomo Corporation in 1999, from 30% to 70%. In October
    2002, we launched the ProteinChip AutoBiomarker System, an
    automated version of our ProteinChip Biomarker System. On
    March 23, 2004, we purchased the remaining 30% ownership
    interest in Ciphergen Biosystems KK. In July 2004, we launched
    the next generation ProteinChip System, Series 4000. We
    have used our resources primarily to develop and expand our
    proprietary ProteinChip Systems and related consumables and to
    establish a marketing and sales organization for
    commercialization of our products. We also used our funds to
    establish a joint venture to distribute our products in Japan
    and to increase our ownership in the joint venture to 100%. In
    addition, we acquired the BioSepra process chromatography
    business in 2001, which we sold for a gain in 2004. We have also
    used our resources to establish Biomarker Discovery Center
    laboratories to provide research services to our clients, to
    foster further adoption of our products and technology, and to
    discover biomarkers that we seek to patent for diagnostic and
    other purposes. In early 2004, we increased our efforts to
    discover and commercialize protein biomarkers and panels of
    biomarkers that can be developed into protein molecular
    diagnostic tests that improve patient care. Since our inception
    we have incurred significant losses and as of December 31,
    2006, we had an accumulated deficit of $217.9 million.
 
    Prior to November 13, 2006, our sales were driven by the
    need for new and better tools to perform protein discovery,
    characterization, purification, identification and assay
    development. Many of the ProteinChip Systems sold to our
    customers also generated a recurring revenue stream from the
    sale of consumables and maintenance contracts. In addition, some
    of our customers later enhanced their ProteinChip Systems by
    adding our automation
    
    25
 
    accessories and advanced software. This recurring revenue stream
    was sold to Bio-Rad as part of the sale of the instrument
    business.
 
    Our expenses have consisted primarily of materials, contracted
    manufacturing services, labor and overhead costs to manufacture
    our ProteinChip Systems and ProteinChip Arrays and to provide
    customer services; marketing and sales activities; research and
    development programs; litigation; and general and administrative
    costs associated with our operations.
 
    We expect to incur losses at least for the next year. Due to the
    asset sale of our instrument business to Bio-Rad, we will have
    limited revenues until our diagnostic tests are developed and
    successfully commercialized. To become profitable, we will need
    to complete development of key diagnostic tests, obtain FDA
    approval and successfully commercialize our products. We have a
    limited history of operations in developing diagnostic tests,
    and we anticipate that our quarterly results of operations will
    fluctuate for the foreseeable future due to several factors,
    including market acceptance of current and new products,the
    timing and results of our research and development efforts, the
    introduction of new products by our competitors and possible
    patent or license issues. Our limited operating history makes
    accurate prediction of future results of operations difficult or
    impossible.
 
    Recent
    Developments
 
    On November 13, 2006, we sold the assets and liabilities of
    our instrument business, which included our SELDI technology,
    ProteinChip®
    Arrays and accompanying software to Bio-Rad Laboratories, Inc.
    pursuant to an asset sale transaction. The Company retains
    certain exclusive rights in the clinical and consumer
    diagnostics market. Bio-Rad purchased the instrument business
    for approximately $16 million in cash which was paid at the
    closing of the transaction. An additional $4.0 million of
    contingent cash consideration includes $2.0 million,
    subject to certain adjustments, to be held in escrow for three
    years as security for certain obligations, and another
    $2.0 million as a holdback amount pending the issuance of a
    re-examination certificate confirming a SELDI patent. Pursuant
    to the asset sale, assets and liabilities of approximately
    $15 million and $7 million, respectively, were sold to
    BioRad. Furthermore, the Company recorded a gain of
    approximately $6.9 million in the fourth quarter of 2006
    relating to the transaction. As a result of the asset sale to
    Bio-Rad, we do not anticipate having significant revenues from
    product sales until the first of our diagnostic tests are
    successfully commercialized. (See Note 6, Gain on
    Sale of Instrument Business, and Note 22
    Subsequent Events, of the Notes to Consolidated
    Financial Statements.).
 
    On November 13, 2006, Bio-Rad and Ciphergen also entered
    into a stock purchase agreement for the sale to Bio-Rad of
    unregistered shares of the Companys common stock for an
    aggregate purchase price of $3,000,000. Bio-Rad was given
    certain registration rights such that if the Company files a
    registration statement, Bio-Rad may elect to include its shares
    in that registration, subject to various conditions.
 
    In connection with the asset sale, the Company also entered into
    a manufacturing services agreement with Bio-Rad whereby the
    Company has agreed to purchase certain SELDI instruments and
    consumables from Bio-Rad for the continued development of its
    diagnostics business.
 
    Also in connection with the asset sale, the Company has entered
    into a cross-license agreement with Bio-Rad whereby the Company
    retains certain rights to exploit existing technology
    commercially, including SELDI technology, in the clinical
    diagnostics market, which market includes the development and
    sale of clinical laboratory products and services, as well as
    home-use diagnostic tests. Ciphergen has an annual obligation
    for three years to purchase of approximately $1,230,000 per
    year of systems and arrays under its manufacturing and supply
    agreement with Bio-Rad.
 
    On November 15, 2006 the Company exchanged
    $27.5 million aggregate principal amount of its
    4.50% Convertible Senior Notes due 2008 for
    $16.5 million aggregate principal amount of a new series of
    7.00% Convertible Senior Notes due 2011 and
    $11.0 million in cash, plus accrued and unpaid interest.
    The new notes will mature on September 1, 2011, and bear
    interest at a rate of 7.00% per year, which may be reduced
    to 4.00% per year if the Company receives approval or
    clearance for commercial sale of any of its ovarian cancer tests
    by the U.S. Food and Drug Administration (FDA). The new
    notes are convertible into the Companys common stock at an
    initial conversion price of $2.00 per share. On or after
    September 1, 2009, the Company may, at its option, redeem
    the new notes for cash in whole at any time or in part from time
    to time, on any date prior to maturity if, beginning on
    
    26
 
    September 1, 2009, the volume-weighted average price per
    share of the Common Stock equals or exceeds 200% of the
    Conversion Price then in effect for at least 20 Trading Days in
    any consecutive 30 Trading Day period ending on the Trading Day
    prior to the date the notice of the redemption.
    $2.5 million of the previously issued notes remain
    outstanding and are due on September 1, 2008.
 
    On May 24, 2006, the Nasdaq Listings Qualification
    Department notified Ciphergen that the Company had failed to
    comply with the continued listing requirements of The Nasdaq
    Global Market because the market value of the Companys
    listed securities had fallen below $50,000,000 for 10
    consecutive business days (pursuant to Rule 4450(b)(1)(A)
    of the Nasdaq Marketplace Rules). Pursuant to Nasdaq Marketplace
    Rule 4450(e)(4), the Company was provided a period of 30
    calendar days, or until September 23, 2006, to regain
    compliance. The Company requested a hearing for purposes of
    appealing this delisting determination on July 3, 2006. On
    August 17, 2006, the Company attended a hearing before a
    Nasdaq Listing Qualifications Panel and requested the
    Companys listing be transferred from the Nasdaq Global
    Market to the Nasdaq Capital Market. On August 24, 2006 the
    Company was notified the transfer was approved effective Monday,
    August 28, 2006. The Companys trading symbol remains
    CIPH.
 
    Critical
    Accounting Policies and Estimates
 
    Our discussion and analysis of our financial condition and
    results of operations are based upon our 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
    us to make estimates and judgments that affect the reported
    amounts of assets, liabilities, revenues and expenses, and
    related disclosure of contingent assets and liabilities. We base
    our estimates on historical experience and on various other
    assumptions 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.
 
    We believe the following critical accounting policies affect our
    more significant judgments and estimates used in the preparation
    of our consolidated financial statements. (See note 1 of
    the Notes to Consolidated Financial Statements.)
 
    Revenue
    Recognition
 
    Through November 13, 2006 we had derived our revenue from
    primarily two sources: (i) product revenue, which included
    systems, accessories, software licenses and consumables, and
    (ii) services and support revenue, which included Biomarker
    Discovery Center services, maintenance, training and consulting
    revenue. As a result of the asset sale to Bio-Rad, future
    revenues will be based on the sales of diagnostic tests once the
    first of these tests is approved by the FDA and commercialized.
    As described below, significant management judgments and
    estimates must be made and used in connection with the revenue
    recognized in any accounting period.
 
    Through November 13, 2006 we had recognized revenue from
    the sales of systems, accessories, separately priced software
    products and consumables when realized or realizable and earned,
    which is when the following criteria are met:
 
    |  |  |  | 
    |  |  | persuasive evidence of an agreement exists, | 
|  | 
    |  |  | the price is fixed or determinable, | 
|  | 
    |  |  | the product has been delivered, | 
|  | 
    |  |  | no significant obligations remain, and | 
|  | 
    |  |  | collection of the receivable is reasonably assured. | 
 
    For all sales prior to November 13, 2006, except for small
    amounts of consumables, we used a binding purchase order,
    contract or signed sales quotation as evidence of an
    arrangement. Sales through our distributors were evidenced by a
    master agreement governing the relationship together with
    binding purchase orders on a
    transaction-by-transaction
    basis.
    
    27
 
 
    At the time of the transaction, we assessed whether the price
    was fixed and determinable and whether or not collection was
    reasonably assured. We assessed whether the price was fixed and
    determinable based on the payment terms associated with the
    transaction. If a significant portion of the payment was due
    after our normal payment terms, which are 30 to 90 days
    from invoice date in most countries, we generally treated the
    price as not being fixed and determinable. In these cases, we
    recognized revenue for the extended portions of the payment as
    they become due. We assessed collectibility based on a number of
    factors, including past transaction history with the customer
    and the creditworthiness of the customer. We did not request
    collateral from our customers. If we determined that collection
    of a payment was not reasonably assured, we deferred the revenue
    until the time collection becomes reasonably assured, which is
    generally upon receipt of cash. The majority of deferred revenue
    was sold to Bio-Rad as part of the asset sale of the instrument
    business. Delivery generally occurred when the product was
    delivered to a common carrier or when the customer received the
    product, depending on the nature of the arrangement. Revenue
    from shipping and handling was generally recognized upon product
    shipment, based on the amount billed to customers for shipping
    and handling. The related cost of shipping and handling was
    included in cost of revenue upon product shipment.
 
    We generally included a standard
    12-month
    warranty on our instruments and accessories in the form of a
    maintenance contract upon initial sale. We also sold separately
    priced maintenance (extended warranty) contracts, which were
    generally for 12 or 24 months following expiration of the
    initial warranty. We made no distinction between a standard
    warranty and a maintenance (extended warranty) contract, as
    coverage under both the standard and an extended maintenance
    contract is identical. Because we did not offer traditional
    warranties but enhanced them such that they are identical to our
    separately priced maintenance contracts, we believe it was
    appropriate to account for them the same way. Revenue for both
    the standard and extended maintenance contracts was deferred and
    recognized ratably over the maintenance contract term. Related
    costs were expensed as incurred. All warranty obligations were
    transferred to Bio-Rad on November 13, 2006 with the sale
    of the instrument business.
 
    For revenue from Biomarker Discovery Center contracts and other
    consulting contracts, if elements were specifically tied to a
    separate earnings process, then revenue related to an element
    was recognized when the specific performance obligation
    associated with that element is completed. When revenues for an
    element were not specifically tied to a separate earnings
    process, they were recognized ratably over the term of the
    agreement. Revenue from Biomarker Discovery Center services and
    other consulting contracts was recognized at the completion of
    key stages in the performance of the service as described in our
    agreement with the customer. Often, there was only a single
    element, namely delivery of a scientific report upon completion
    of our analysis of customer samples, in which case we recognized
    all the revenue upon the conclusion of the project when all
    deliverables had been provided to the customer. Revenue was
    deferred for fees received before earned. Our training was
    billed based on published course fees and we generally
    recognized revenue as the training is provided to the customer.
    On November 13, 2006, the Biomarker Discovery Centers and
    their related contracts were transferred to Bio-Rad as part of
    the asset sale. There had been no further revenue from the
    Biomarker Discovery Centers after the asset sale.
 
    For revenue arrangements with multiple elements that were
    delivered at different points in time (for example, where we
    have delivered the hardware and software but were also obligated
    to provide services, maintenance
    and/or
    training), we evaluated whether the delivered elements have
    standalone value to the customer, whether the fair value of the
    undelivered elements was reliably determinable, and whether the
    delivery of the remaining elements was probable and within our
    control. When all these conditions were met, we recognized
    revenue on the delivered elements. If any one of these
    conditions was not met, we deferred the recognition of revenue
    until all these conditions were met or all elements had been
    delivered. Fair values for ongoing maintenance are based upon
    separate sales of renewals to other customers. Fair values for
    services, such as training or consulting, were based upon
    separate sales by us of those services to other customers.
 
    Allowance
    for Doubtful Accounts
 
    We maintain allowances for doubtful accounts for estimated
    losses resulting from the inability of our customers to make
    required payments. These reserves are determined by analyzing
    specific customer accounts that have known or potential
    collection issues, and reviewing the length of time receivables
    are outstanding and applying historical loss rates to the aging
    of the accounts receivable balances. If the financial condition
    of
    
    28
 
    Ciphergens customers were to deteriorate, resulting in an
    impairment of their ability to make payments, additional
    allowances would be required.
 
    Inventory
    Reserves
 
    As December 31, 2006, we have no inventory available for
    sale as a result of the asset sale to Bio-Rad. We will have
    limited inventories until we complete the development and
    commercialization of our diagnostic tests. We write down our
    inventory for estimated excess and obsolete inventory equal to
    the difference between the cost of inventory and the estimated
    market value based upon assumptions about future demand, market
    conditions and the release of new products that will supersede
    older ones. Such estimates were difficult to make under volatile
    economic conditions. Reviews for excess inventory were done on a
    quarterly basis and required reserve levels were calculated with
    reference to our projected ultimate usage of that inventory. In
    order to determine the ultimate usage, we took into account
    recent sales forecasts, historical experience, projected
    obsolescence and our current inventory levels.
 
    Depreciation
    and Amortization
 
    Property, plant and equipment are stated at cost less
    accumulated depreciation and amortization. Depreciation and
    amortization are computed for financial reporting purposes
    principally using the straight-line method over the following
    estimated useful lives: machinery and equipment, 3-5 years;
    demonstration equipment, 2 years; computer equipment,
    development systems used for collaborations and software,
    3 years; furniture and fixtures, 5 years; buildings
    and leasehold improvements, the lesser of their economic life or
    the term of the underlying lease. The cost of repairs and
    maintenance is charged to operations as incurred. Gains and
    losses resulting from disposals of assets are reflected in the
    year of disposition.
 
    Valuation
    of Long-Lived Assets Including Acquired Intangible
    Assets
 
    We review long-lived assets, which include property, plant and
    equipment and acquired identifiable intangibles, for impairment
    whenever events or changes in circumstances indicate that the
    carrying amount of an asset may not be recoverable. Impairment
    evaluations involve management estimates of the useful lives of
    the assets and the future cash flows they are expected to
    generate. An impairment loss is recognized when estimated
    undiscounted future cash flows expected to result from the use
    of the asset plus net proceeds expected from disposition of the
    asset (if any) are less than the carrying value of the asset.
    This approach also uses our estimates of future market growth,
    forecasted revenue and costs and appropriate discount rates.
    Actual useful lives, cash flows and other factors could be
    different from those estimated by management and this could have
    a material effect on our operating results and financial
    position. When impairment is identified, the carrying amount of
    the asset is reduced to its estimated fair value. Deterioration
    of our business for a significant product or in a particular
    geographic region in the future could also lead to impairment
    adjustments as such issues are identified. In connection with
    the November 13, 2006 sale of the instrument business,
    there are no longer any intangible assets recorded on our
    balance sheet as these intangible assets were associated with
    the instrument business sold to Bio-Rad.
 
    Goodwill
    Impairment
 
    We recorded goodwill principally as a result of our acquisitions
    of IllumeSys Pacific, Inc. in 1997, Ciphergen Technologies, Inc.
    in 1998 and BioSepra S.A. in 2001, and the increases in our
    ownership of Ciphergen Biosystems KK in 2002 and 2004. The
    goodwill related to BioSepra was written off against the gain on
    the sale of the BioSepra business in 2004. We perform goodwill
    impairment tests on an annual basis and more frequently when
    events and circumstances occur that indicate a possible
    impairment of goodwill. In determining whether there is an
    impairment of goodwill, we calculate the estimated fair value of
    the reporting unit in which the goodwill is recorded using a
    discounted future cash flow method. We then compare the
    resulting fair value to the net book value of the reporting
    unit, including goodwill. If the net book value of a reporting
    unit exceeds its fair value, we measure the amount of the
    impairment loss by comparing the implied fair value of the
    reporting units goodwill with the carrying amount of that
    goodwill. To the extent that the carrying amount of a reporting
    units goodwill exceeds its implied fair value, we
    recognize a goodwill impairment loss. We performed annual
    impairment tests through 2004 and determined that no impairment
    had occurred. We performed an annual impairment test in 2005 and
    determined that goodwill of
    
    29
 
    $2.5 million associated with our Japanese subsidiary had
    been impaired. (See Note 5, Purchase of Additional
    Ownership Interest in Ciphergen Biosystems KK, and
    note 8, Goodwill and Other Intangible Assets,
    in the Notes to Consolidated Financial Statements.) The
    discounted future cash flow method used in the first step of our
    impairment test involves significant estimates including future
    cash inflows from estimated revenues, future cash outflows from
    estimated project costs and general and administrative costs,
    timing of collection and payment of various items, working
    capital levels, future growth rates and profit margins, as well
    as discount rate and terminal value assumptions. Although we
    believe the estimates and assumptions that we used in testing
    for impairment are reasonable, changes in any one of these
    assumptions could produce a significantly different result. In
    connection with the November 13, 2006 sale of the
    instrument business, there is no longer any goodwill recorded on
    our balance sheet as goodwill was associated with the instrument
    business and accordingly were written off.
 
    Stock-Based
    Compensation
 
    We have various stock option, stock purchase and incentive plans
    to reward employees and key executive officers of our company.
    Effective January 1, 2006, the Company adopted
    SFAS No. 123 (revised), Share-Based
    Payment (SFAS 123(R)), using the modified
    prospective transition method. Under this new standard, the
    Companys estimate of compensation expense requires a
    number of complex and subjective assumptions, including the
    price volatility of Ciphergens common stock, employee
    exercise patterns (expected life of the options), future
    forfeitures and related tax effects. Prior to the adoption of
    SFAS 123(R), the Company accounted for stock option grants
    using the intrinsic value method, in accordance with APB Opinion
    No. 25, Accounting for Stock Issued to
    Employees (APB 25), and accordingly,
    recognized no compensation expense for stock option grants.
 
    Under the modified prospective approach, SFAS 123(R)
    applies to new awards and to awards that were outstanding on
    January 1, 2006 that are subsequently modified, repurchased
    or cancelled. Under the modified prospective approach,
    compensation cost recognized in 2006 includes compensation cost
    for all stock-based payments granted prior to, but not yet
    vested as of, January 1, 2006, based on the grant-date fair
    value estimated in accordance with the original provisions of
    SFAS 123, and compensation cost for all stock-based
    payments granted subsequent to January 1, 2006, based on
    the grant-date fair value estimated in accordance with the
    provisions of SFAS 123(R). Prior periods were not restated
    to reflect the impact of adopting the new standard.
 
    As a result of adopting SFAS 123(R) on January 1,
    2006, the Companys net loss and basic and diluted net loss
    per share for the year ended December 31, 2006 was
    $1.6 million and $0.04 higher, than if the Company had
    continued to account for stock-based compensation under
    APB 25 for its stock option grants. The Company has a 100%
    valuation allowance recorded against its deferred tax assets.
    Therefore SFAS 123(R) had no effect on the income tax
    provision in the consolidated statement of operations or the
    consolidated statement of cash flows. There was no stock based
    compensation expense during fiscal year 2005. For fiscal year
    2004, stock based compensation expense of $602,000 was related
    to amortization of our deferred stock compensation expense from
    our initial public offering.
 
    Contingencies
 
    We have been, and may in the future become, subject to legal
    proceedings related to intellectual property licensing matters.
    Based on the information available at the balance sheet dates
    and through consultation with our legal counsel, we assess the
    likelihood of any adverse judgments or outcomes for these
    matters, as well as potential ranges of probable loss. If losses
    are probable and reasonably estimable, we will record a reserve
    in accordance with Statement of Financial Accounting Standards
    No. 5, Accounting for Contingencies. Currently
    we have no such reserves recorded. Any reserves recorded in the
    future may change due to new developments in each matter.
 
    Deferred
    Taxes
 
    We record a valuation allowance to reduce our deferred tax
    assets to the amount that is more likely than not to be
    realized. While we have considered future taxable income and
    ongoing prudent and feasible tax planning strategies in
    assessing the need for the valuation allowance, in the event we
    were to determine that Ciphergen 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. Likewise,
    should we
    
    30
 
    determine that Ciphergen would not be able to realize all or
    part of its net deferred tax asset in the future, an adjustment
    to the deferred tax asset would be charged to income in the
    period such determination was made.
 
    Results
    of Operations
 
    Comparison
    of Years Ended December 31, 2006, 2005 and
    2004
 
    Revenue
 
    Product revenue was $11.3 million in 2006,
    $18.4 million in 2005, and $31.4 million in 2004. The
    $7.1 million or 39% decrease in product revenue from 2005
    to 2006 was largely the result of a 38% decrease in revenue from
    sales of our ProteinChip Systems, accessories and software, as
    well as a 39% decrease in revenue from our arrays and
    consumables. The decrease in systems and related revenue was due
    to a 55% decrease in unit sales of ProteinChip Systems from 76
    systems in 2005 to 34 in 2006 in part due to the asset sale of
    our instrument business to Bio-Rad. During the first half of
    2006, product revenues trended down by about 10% from the prior
    year and dropped significantly following the announcement of the
    proposed transaction with Bio-Rad. The decrease in array and
    consumable sales was largely driven by lower unit sales due in
    part to significantly reduced new instrument placements, as new
    instrument placements typically included a significant initial
    purchase of consumables.
 
    The $13.0 million or 42% decrease in product revenue from
    2004 to 2005 was largely the result of a 54% decrease in revenue
    from sales of our ProteinChip Systems, accessories and software,
    as well as a 14% decrease in revenue from our arrays and
    consumables. The decrease in systems and related revenue was due
    to a 41% decrease in unit sales of ProteinChip Systems and a 22%
    decrease in average revenue per system sold due to increased
    discounting and incentives we offered to expedite orders,
    discounts offered to customers on trade ins of their older model
    ProteinChip Systems for a new Series 4000, and the
    competitive environment. The decrease in array and consumable
    sales was largely driven by lower unit sales due in part to
    fewer new instrument placements, which typically include a
    significant initial purchase of consumables. In Japan, the
    strengthening of the U.S. dollar against the Japanese yen
    resulted in a decrease in product revenue of approximately
    $370,000.
 
    In the third quarter of 2005, the Company sold nine ProteinChip
    Systems to one customer for $601,000. The Company also entered
    into a product development agreement with this same customer,
    whereby the customer will develop for Ciphergen a specific new
    product and Ciphergen may pay the customer up to $500,000 based
    on the customers attainment of specified development
    milestones. Under this agreement, Ciphergen paid this customer
    $300,000 of development fees during 2005. This was recorded,
    following EITF
    01-9,
    Accounting for Consideration Given by a Vendor to a
    Customer (Including a Reseller of the Vendors
    Products), as a reduction to revenue, resulting in net
    revenue from this customer of approximately $301,000 in 2005.
    This constituted approximately 2% of products revenue and 1% of
    total revenue for 2005. No additional payment was made in 2006.
    With the divestiture of the instrument business to Bio-Rad, this
    product development agreement was transferred to Bio-Rad.
 
    Service revenue was $6.9 million in 2006, $8.9 million
    in 2005, and $8.8 million in 2004. The $2.0 million or
    22% decrease in service revenue from 2005 to 2006 was primarily
    due to fewer new instrument placements, which typically include
    an initial registration for one or more training classes, and
    the closing of the asset sale to Bio-Rad in the fourth quarter
    of 2006.
 
    The $93,000 or 1% increase in service revenue from 2004 to 2005
    was primarily due to a $313,000 increase in revenue from
    collaboration services handled through our Biomarker Discovery
    Center laboratories due to the completion of several large
    contracts in 2005, and from a $97,000 increase in revenue from
    maintenance contracts, driven by growth in our installed base.
    However, revenue from training and consulting services decreased
    $317,000 primarily due to fewer new instrument placements, which
    typically include an initial registration for one or more
    training classes.
 
    We expect that future revenues for our business will be affected
    by, among other things, our ability to develop and commercialize
    diagnostic tests, new product and application introductions,
    customer budgets, competitive conditions and government funding
    for research in our field. We expect limited revenues in 2007
    until the new diagnostic tests are developed and launched.
    
    31
 
 
    Cost of
    Revenue
 
    Cost of product revenue was $5.8 million in 2006,
    $9.4 million in 2005, and $11.2 million in 2004. The
    $3.6 million or 38% decrease in cost of product revenue
    from 2005 to 2006 resulted from a decrease in unit sales of our
    ProteinChip Systems, accessories, software, arrays and other
    consumables. The decrease in gross margin of $3.5 million
    for product revenue was largely due to the aforementioned drop
    in unit sales. Gross margin as a percentage of sales for product
    revenue was relatively flat at 48.9% of sales in 2005 and 48.5%
    of sales in 2006.
 
    The $1.8 million or 16% decrease in cost of product revenue
    from 2004 to 2005 resulted from a decrease in unit sales of our
    ProteinChip Systems, accessories, software, arrays and other
    consumables, as well as a $1.1 million decrease in the
    provision for excess and obsolete inventories in 2005 compared
    to 2004. We introduced our current Series 4000 platform in
    2004 and concurrently increased inventory reserves for older
    products. These decreases were partially offset by higher costs
    of materials recorded in 2005, compared to 2004 when a portion
    of sales included instruments with components previously charged
    to research and development. The gross margin for product
    revenue decreased from 64% in 2004 to 49% in 2005. The decrease
    in gross margin for product revenue was largely due to lower
    gross margins for arrays and consumables resulting from lower
    production volumes in 2005 compared to 2004, thus spreading our
    fixed manufacturing overhead costs over fewer units produced and
    eroding gross margin on products revenue by approximately 12% of
    products revenue. The decrease in gross margin from 2004 to 2005
    was also due to lower gross margins for ProteinChip Systems as a
    result of increased discounting.
 
    Stock-based compensation expense related to employee stock
    options under SFAS 123(R) in cost of product revenue was
    $144,000 in 2006. Deferred stock-based compensation expense in
    cost of product revenue was $0 in 2005 and $45,000 in 2004.
 
    Cost of service revenue was $3.5 million in 2006,
    $4.3 million in 2005, and $3.9 million in 2004. From
    2006 to 2005, cost of service revenue decreased
    $0.8 million or 19% primarily due the 22% decrease in
    service revenues. The gross margin for service revenue decreased
    from 51% in 2005 to 49% in 2006 due to the drop in service
    revenues.
 
    From 2004 to 2005, cost of service revenue increased $445,000 or
    11% primarily due to increased costs associated with paid
    projects performed by our Biomarker Discovery Center
    laboratories and customer training. The gross margin for service
    revenue decreased from 56% in 2004 to 51% in 2005 mainly due to
    lower gross margins realized on Biomarker Discovery Center
    contracts, which have costs that typically vary based on the
    complexity and difficulty of the work being undertaken, and
    lower gross margins on our training services.
 
    We believe that gross profits for 2007 will be minimal until the
    new diagnostic tests are developed and successfully
    commercialized.
 
    Operating
    Expenses
 
    Research
    and Development
 
    Research and development expenses were $11.5 million in
    2006, $13.2 million in 2005, and $19.3 million in
    2004. From 2005 to 2006, research and development expenses
    decreased $1.7 million or 13% primarily due to a decrease
    of $2.4 million in salaries, payroll taxes and employee
    benefits due to transition to diagnostic testing and away from
    tools development following the asset sale to Bio-Rad. Materials
    and supplies used in the development of new products also
    decreased by $0.6 million, depreciation decreased by
    $0.1 million, travel expenses decreased by
    $0.1 million and consulting fees decreased by
    $0.1 million, consistent with the scaling back of research
    programs related to our instrument platform. These decreases
    were partially offset by a $1.4 million increase in
    clinical collaboration expenses and a $0.3 million increase
    in stock-based compensation expense related to employee stock
    options under SFAS 123(R). Spending on diagnostics research
    under the strategic alliance with Quest Diagnostics was
    approximately $5.4 million in 2006 and $2.2 million in
    2005.
 
    From 2004 to 2005, research and development expenses decreased
    $6.1 million or 32% primarily due to a decrease of
    $2.2 million in salaries, payroll taxes and employee
    benefits due to a 39% decline in research and development staff.
    Materials and supplies used in the development of new products
    also decreased by $1.9 million
    
    32
 
    and consulting fees decreased by $1.0 million, consistent
    with the scaling back of research programs related to our
    instrument platform.
 
    Stock-based compensation expense related to employee stock
    options under SFAS 123(R) in research and development
    expenses was $337,000 in 2006. Deferred stock-based compensation
    expense in research and development expenses was $0 in 2005, and
    $37,000 in 2004.
 
    We expect research and development expenses to decline in 2007
    relative to 2006 due to having fewer research and development
    employees in 2006 needed to support our research and development
    activities associated with developing and commercializing
    diagnostic tests as part of our strategic alliance with Quest
    Diagnostics, and discovering biomarkers that could potentially
    be developed into additional diagnostic products.
 
    Sales and
    Marketing
 
    Sales and marketing expenses were $12.6 million in 2006,
    $18.0 million in 2005, and $26.0 million in 2004. From
    2005 to 2006, sales and marketing expenses decreased
    $5.4 million or 30%, largely due to lower payroll-related
    costs as a result of a reduction in sales and marketing
    headcount from 72 people in 2005 to 6 people at the
    end of 2006 due to the asset sale of our instrument business to
    Bio-Rad. The primary components of the decrease in expense from
    2005 were payroll and related costs of approximately
    $2.8 million, $0.9 million decrease in travel expenses
    and a $0.6 million decrease in field materials and supplies
    expense.
 
    From 2004 to 2005, sales and marketing expenses decreased
    $8.0 million or 31%, largely due to lower payroll-related
    costs as a result of a 40% decrease in the sales and marketing
    staff thereby decreasing payroll and related costs approximately
    $4.1 million. The reduction in our sales force also
    resulted in a $1.6 million decrease in travel expenses and
    a $0.6 million decrease in ProteinChip Arrays and lab
    supplies used for customer demonstrations. The cost of
    advertising, trade shows and other promotional activities
    declined by approximately $1.2 million as 2004 expenses
    were unusually high in 2004 due to the launch of our
    Series 4000 ProteinChip System.
 
    Stock-based compensation expense related to employee stock
    options under SFAS 123(R) in sales and marketing expenses
    was $321,000 in 2006. Deferred stock-based compensation expense
    in sales and marketing expenses was $0 in 2005, and $93,000 in
    2004.
 
    We expect sales and marketing expenses to decrease in 2007
    relative to 2006 as a result of a smaller sales force and
    reduced associated selling expenses until the launch of new
    diagnostics tests.
 
    General
    and Administrative
 
    General and administrative expenses were $10.7 million in
    2006, $14.4 million in 2005, and $14.1 million in
    2004. From 2005 to 2006, general and administrative expenses
    decreased $3.7 million or 26%, largely driven by a
    $2.1 million reduction in payroll and related costs
    resulting from a reduction in headcount related expenses due to
    the asset sale to Bio-Rad. Outside legal fees decreased
    approximately $0.4 million due to decreased patent
    registration activity which were partially offset by legal fees
    related to defense of a SELDI patent. Other audit and accounting
    fees decreased $1.3 million as 2005 audit costs were much
    higher due to the restatement of earnings in 2005.
 
    From 2004 to 2005, general and administrative expenses increased
    $268,000 or 2%, largely driven by $679,000 in severance costs
    for two former executives, partly offset by a $142,000 reduction
    in payroll and related costs resulting from a 32% reduction in
    administrative staff which occurred in the second half of 2005.
    Outside professional fees increased approximately $429,000 as a
    result of work done to assist us with our restatement of our
    second quarter 2005 financial statements. Other audit and
    accounting fees increased $321,000, largely the result of
    efforts to comply with Section 404 of the Sarbanes-Oxley
    Act of 2002. These increases were partially offset by decreases
    of $427,000 in stock-based compensation expense, $249,000 in
    costs of temporary help, $165,000 in travel expenses and
    $124,000 in the provision for bad debts.
 
    Stock-based compensation expense related to employee stock
    options under SFAS 123(R) in general and administrative
    expenses were $813,000 in 2006. Deferred stock-based
    compensation expense in general and administrative expenses was
    $0 in 2005, and $427,000 in 2004.
    
    33
 
 
    We expect general and administrative expenses to drop slightly
    in 2007 relative to 2006 due to lower headcount in the
    administration function which will be partially offset by the
    costs of performing a management assessment of compliance with
    Section 404 of the Sarbanes-Oxley Act of 2002
 
    Goodwill
    Impairment
 
    We recorded goodwill principally as a result of our acquisition
    of BioSepra in 2001, the increases in our ownership of Ciphergen
    Biosystems KK in 2002 and 2004, and the acquisitions of
    Ciphergen Technologies, Inc. and IllumeSys Pacific, Inc. in 1997
    and 1998. We performed annual impairment tests from 2002 through
    2004 and determined that no impairment had occurred. The
    goodwill related to BioSepra was written off against the sale of
    the BioSepra business in 2004. Due to Ciphergen Biosystems
    KKs lower than expected operating results and cash flows
    throughout 2005 and based on revised forecasted results, a
    goodwill impairment loss of $2.5 million was recognized in
    the fourth quarter of 2005. The fair value of Ciphergen
    Biosystems KK was estimated using expected discounted cash
    flows. (See Note 5, Purchase of Additional
    Ownership Interest in Ciphergen Biosystems KK, and
    Note 8, Goodwill and Other Intangible Assets,
    of the Notes to Consolidated Financial Statements.).

    Gain on sale of instrument
    business to Bio-Rad
 |  | $ | 6,929 |  | 
|  |  |  |  |  | 
 
    Bio-Rad and Ciphergen entered into a Stock Purchase Agreement
    (the Purchase Agreement) for the private sale of
    shares of the Companys common stock to Bio-Rad for an
    aggregate purchase price of $3,000,000. The purchase price of
    $0.972 per share was based on the average closing price for
    the 5 days preceding the Agreement on August 14, 2006.
    For accounting purposes, the 3,086,420 shares purchased are
    valued at $1.17 per share, the closing price on
    November 13, 2006, the day the transaction closed. The
    resulting value of $3.611 million was allocated between
    Common stock (3.086 million shares at $0.001 par
    value) and Additional paid-in capital of $3.608 million. An
    additional $4.0 million of contingent cash consideration
    included $2.0 million, subject to certain adjustments, to
    be held in escrow as security for certain obligations of the
    Company for three years following the closing, and
    $2.0 million as a holdback amount to be held by Bio-Rad
    until the issuance of a re-examination certificate confirming a
    SELDI patent. (See Note 6, Gain on Sale of Instrument
    Business, and Note 22 Subsequent Events,
    of the Notes to Consolidate Financial Statements.).
    
    34
 
 
    Loss on
    Extinguishment of Debt
 
    The loss from extinguishment of debt represents the expensing of
    $868,000 of unamortized debt discount and $613,000 of
    unamortized prepaid offering costs related to the exchange of
    $27.5 million of our 4% convertible senior notes due
    September 1, 2008 for $16.5 million of
    7% convertible notes and $11 million in cash. (See
    Note 11, Long-term Debt and Capital Leases, of
    the Notes to Consolidated Financial Statements).
 
    Interest
    and Other Income (Expense), Net
 
    Interest income was $843,000 in 2006, $839,000 in 2005, and
    $505,000 in 2004. Interest income from money market and accounts
    remained flat between 2005 and 2006. Although money market
    account balances decreased from $28.0 million in 2005 to
    $17.7 million in 2006 this was offset by interest yield,
    which steadily increased from 2.9% in June 2005 to 5.9% in
    December 2006. The increase of $334,000 from 2004 to 2005 was
    largely due to higher interest rates.
 
    Interest expense was $2.3 million in 2006 and
    $2.0 million in both 2005 and 2004. Interest expense
    increased $0.3 million from 2005 to 2006 primarily due to
    the increase in interest paid to Quest due to Ciphergens
    outstanding loan balance from Quest increasing from
    $2.5 million to $7.1 million from December 31,
    2005 to December 31, 2006.
 
    Other expense was $125,000 in 2006, $717,000 in 2005, and
    $649,000 in 2004. In 2006 other expense consisted primarily of
    $332,000 of amortization of issuance costs for the convertible
    senior notes partially offset by $81,000 for the return of a
    lease deposit. In 2005, other expense consisted primarily of
    $373,000 of expense for the amortization of issuance costs for
    the convertible senior notes and foreign exchange losses of
    approximately $232,000, largely due to the impact on the
    transaction losses from the decline of the U.S. dollar
    against the British pound and the Japanese yen. In 2004, other
    expense consisted mainly of $373,000 in expense associated with
    the amortization of issuance costs for the convertible senior
    notes. Subsequent to our acquisition of majority control of
    Ciphergen Biosystems KK on August 31, 2002 and prior to our
    acquisition of 100% control of Ciphergen Biosystems KK at the
    end of the first quarter of 2004, we attributed a share of this
    joint ventures income or losses to SC BioSciences (a
    subsidiary of Sumitomo Corporation) minority interest. For 2004,
    we attributed $0 of loss to minority interest, as cumulative
    losses attributable to the minority shareholder exceeded
    previous income.
 
    Income
    Taxes
 
    Our provision for income taxes was due to current foreign income
    taxes, which were $152,000, $7,000, and $172,000 for the years
    ended December 31, 2006, 2005 and 2004, respectively,
    including discontinued operations. Excluding discontinued
    operations, current foreign income taxes were an expense of
    $152,000, $7,000, and $109,000, for the years ended
    December 31, 2006, 2005 and 2004, respectively.
 
    We have incurred net losses since inception and consequently are
    not subject to corporate income taxes in the U.S. to the
    extent of our tax loss carryforwards. At December 31, 2006
    we had net operating loss carryforwards of approximately
    $125 million for federal and $58.8 million for state
    tax purposes. If not utilized, these carryforwards will begin to
    expire beginning in 2009 for federal purposes and 2007 for state
    purposes. As of December 31, 2006, Ciphergen has
    $2.9 million of net operation carryforwards from its Japan
    operations. If not utilized, this carry forward will begin to
    expire beginning in 2012. We also have research credit
    carryforwards of approximately $4.4 million and
    $4.7 million for federal and state tax purposes,
    respectively. If not utilized, the federal research credit
    carryforwards will expire in various amounts beginning in 2011.
    The California research credit can be carried forward
    indefinitely. The utilization of net operating loss
    carryforwards to reduce future income taxes will depend on our
    ability to generate sufficient taxable income prior to the
    expiration of the net operating loss carryforwards. In addition,
    the maximum annual use of the net operating loss carryforwards
    may be limited in situations where changes occur in our stock
    ownership.
 
    We have incurred income tax liabilities primarily in France and
    Japan, as well as in most of the other countries outside the
    U.S. in which we operate. We have used net operating loss
    carryforwards to reduce our income tax liabilities in Japan and
    the United Kingdom. We fully utilized our Japanese net operating
    loss carryforwards in
    
    35
 
    2004, resulting in higher 2004 Japanese income tax liability,
    although this was followed in 2005 and 2006 by a net loss. The
    2005 and 2006 net loss can be carried forward for seven
    years. We expect to fully utilize our U.K. net operating loss
    carryforwards in 2007.
 
    Income
    (Loss) From Discontinued Operations, Net of Tax
 
    Discontinued operations includes all revenue, cost of revenue,
    operating expenses, interest expense, other income (expense) and
    tax provisions related to our BioSepra business, which was sold
    to Pall Corporation on November 30, 2004. Loss from
    discontinued operations was $0 in 2006 and 2005, and
    $1.8 million in 2004.

    BioSepras business was characterized by a relatively low
    number of orders for large quantities of customer-specific
    products, often $250,000 to $1.5 million or more per order
    that were utilized and consumed by pharmaceutical customers to
    manufacture biological therapeutics. Filling these large orders
    entailed a lengthy and highly controlled manufacturing process
    at BioSepra, and customers typically ordered several years of
    supply to be manufactured at one time and provided to them in a
    few large deliveries for storage in environmentally-controlled
    facilities to minimize batch variability. BioSepra generally
    priced its products in Euros.

    In addition, $1.0 million was placed in an interest-bearing
    escrow account for one year, after which that amount plus
    $21,000 of accrued interest was paid to Ciphergen and treated as
    an additional gain of $1,021,000 on the sale in 2005. This was
    partly offset by a $67,000 reduction of the gain on the sale of
    the BioSepra business for a post-closing adjustment in 2005, in
    accordance with the Asset Purchase Agreement, resulting in a net
    gain of $954,000 in 2005.
 
    Liquidity
    and Capital Resources
 
    From our inception through December 31, 2006, we have
    financed our operations principally with $229.2 million
    from the sales of products and services to customers and net
    proceeds from debt and equity financings totaling approximately
    $163.8 million. This includes net proceeds of
    $92.4 million from our initial public offering in September
    2000, net proceeds of $26.9 million from our Series E
    Preferred Stock financing in March 2000, net proceeds of
    $15.0 million from the sale of 6,225,000 shares of our
    common stock and a warrant for 2,200,000 shares of our
    common stock to Quest Diagnostics on July 22, 2005 and
    $19.0 million in proceeds from Bio-Rad on November 13,
    2006 in connection with our sale of the instrument business and
    from our sale of 3,086,420 shares of common stock. In
    addition, in July 2005, Quest Diagnostics agreed to loan us up
    to $10 million with interest accrued at the prime rate plus
    0.5% and paid monthly, solely to fund certain development
    activities related to our strategic alliance, against which we
    had borrowed approximately $7.1 million as of
    December 31, 2006. We also received net proceeds of
    $27.0 million from the sale of our BioSepra business in
    November 2004 . An additional $1.0 million plus accrued
    interest which was in an interest-bearing escrow account for one
    year after the sale of our BioSepra business was paid to us on
    December 1, 2005.
 
    Cash, cash equivalents and short-term investments at
    December 31, 2006 were $17.7 million, compared to
    $28.0 million at December 31, 2005. Working capital at
    December 31, 2006 was $13.0 million, compared to
    $27.1 million at December 31, 2005. The decrease in
    working capital was principally due to a net $10.3 million
    decrease in cash and investments to fund our operating losses of
    $22.1 million and $11.0 million of repayments on
    
    37
 
    our 4% senior convertible notes, partially partly offset by
    cash receipts of $16 million for the Asset Sale to Bio-Rad,
    $4.6 million in loan proceeds from Quest Diagnostics, and
    $3.0 million in proceeds for the sale of common stock to
    Bio-Rad.
 
    In addition, there was a $3.2 million decrease in accounts
    receivable net of accounts receivable transferred to Bio-Rad,
    reflecting the decline in revenue from continuing operations in
    2006 compared to 2005, and a $0.2 million decrease in
    inventory net of inventory sold to Bio-Rad which resulted from
    our reducing raw materials purchases as we no longer need
    inventory for sale until we obtain FDA approvals for the
    diagnostics tests currently under development. These decreases
    were partially offset by a $1.1 million decrease in
    accounts payable and accrued liabilities due to our cost-cutting
    measures and reduced inventory purchases, and a
    $1.2 million decrease in current deferred revenue
    consistent with our lower revenues. Long-term debt and capital
    lease balances at December 31, 2005 totaled
    $31.5 million, compared to $29.4 million at
    December 31, 2004, largely due to a loan draw down of
    $2.5 million from the line of credit provided by Quest
    Diagnostics.
 
    Net cash used in operating activities was $20.4 million in
    2006 compared to $22.9 million in 2005. Less cash was
    collected from customers in 2006 as compared to 2005 due
    primarily to a $9.0 million drop in sales in 2006 resulting
    in a $3.2 million net drop in accounts receivables and
    $0.1 million in inventory after considering the transfer of
    accounts receivable and inventory to Bio-Rad as part of the
    asset sale, partially offset by an combined decrease in accounts
    payable and deferred revenue of $2.2 million. Net cash used
    in operating activities was $22.9 million in 2005 compared
    to $32.5 million in 2004. Less cash was collected from
    customers in 2005 as compared to 2004 due to $13.0 million
    in lower sales in 2005. Cash used in operating activities was
    mainly to fund payroll, inventory purchases and operating
    expenses. The decrease in cash collected was offset by an
    increase in interest income received in 2005 as compared to 2004
    as a result of higher interest rates.
 
    Net cash provided by investing activities was $16.5 million
    in 2006 compared to net cash used in investing activities of
    $3.5 million in 2005. Net cash provided by investing
    activities in 2006 primarily resulted from $16 million in
    proceeds from the asset sale of our instrument business to
    Bio-Rad and $2.2 million in maturities of short term
    investments partially offset by purchases of fixed assets of
    $0.6 million, asset sale transaction costs of
    $0.8 million, and $0.5 million for a technology
    license related to our litigation which was settled in 2003. Net
    cash used in investing activities was $3.5 million in 2005
    compared to net cash provided by investing activities of
    $34.0 million in 2004. Net cash used in investing
    activities in 2005 included property and equipment purchases of
    $2.8 million and payments of $587,000 for a technology
    license related to our litigation which was settled in 2003. We
    also paid $1.1 million to Pall Corporation for post-closing
    adjustments related to the sale of our BioSepra business, and we
    received $1.0 million plus $21,000 of accrued interest from
    an escrow account related to the sale of our BioSepra business.
    We anticipate capital expenditures of approximately $750,000 in
    2007.
 
    Net cash used in financing activities was $4.2 million in
    2006 compared with net cash provided by financing activities in
    2005 of $17.2 million in 2005. The decrease resulted
    primarily from $11.0 million for repayments of senior
    convertible debt partially offset by the receipt of
    $4.6 million in loans from Quest Diagnostics and the sale
    of $3.0 million of capital stock to Bio-Rad. Net cash
    provided by financing activities was $17.2 million in 2005
    compared to $792,000 in 2004. The increase resulted primarily
    from $15.0 million in net proceeds from the sale of our
    common stock to Quest Diagnostics and the receipt of
    $2.5 million in loans from Quest Diagnostics. There was
    also a repayment of one stockholder loan in the aggregate
    principal amount of $349,000, and the issuance of common stock
    under our stock option and employee stock purchase plans of
    $349,000, offset by repayments of an equipment financing loan of
    $925,000 and the repayment of capital lease obligations of
    $24,000.
 
    At December 31, 2006, the Company had an accumulated
    deficit of $217.9 million. Management believes that
    currently available resources together with existing debt
    facilities will not be sufficient to fund the Companys
    obligations. The Companys ability to continue to meet its
    obligations and to achieve its business objectives is dependent
    upon, among other things, raising additional capital or
    generating sufficient revenue in excess of costs. At such time
    as the Company requires additional funding, the Company may seek
    to raise such additional funding from various sources, including
    the public equity market, private financings, sales of assets,
    collaborative arrangements and debt. If additional capital is
    raised through the issuance of securities convertible into
    equity, stockholders will experience dilution, and such
    securities may have rights, preferences or privileges senior to
    those of the holders of common stock or convertible senior
    notes. If the Company obtains additional funds through
    
    38
 
    arrangements with collaborators or strategic partners, it may be
    required to relinquish its rights to certain technologies or
    products that it might otherwise seek to retain. There can be no
    assurance that the Company will be able to obtain such
    financing, or obtain it on acceptable terms. If Ciphergen is
    unable to obtain financing on acceptable terms, it may be unable
    to execute its business plan, it could be required to delay or
    reduce the scope of its operations, and it may not be able to
    pay off the convertible senior notes if and when they come due.
 
    The Companys inability to operate profitably and to
    consistently generate cash flows from operations, its reliance
    on external funding either from loans or equity, raise
    substantial doubt about the Companys ability to continue
    as a going concern.
 
    The following summarizes Ciphergens contractual
    obligations at December 31, 2006, and the effect such
    obligations are expected to have on our liquidity and cash flow
    in future periods (in thousands).

|  | 
    |  |  | On October 13, 2006, the company entered into a two year
    research and collaboration agreement with The Ohio State
    University Research Foundation directed at discovery,
    purification, identification
    and/or
    validation of Biomarkers related to thrombotic thrombocytopenic
    purpura and production of associated technology. Under the terms
    of the agreement, Ciphergen will have exclusive rights to
    license discoveries made during the course of this
    collaboration. Ciphergen will pay the financial contribution to
    the University in consideration for costs incurred by the
    University specifically used in furtherance of this research
    program for $149,500  in total during the first 15 months
    of the agreement. The contribution of $149,500 is
    non-cancelable. There is no financial contribution obligation
    for the balance of the two year term. | 
|  | 
    |  |  | On December 21, 2006, the company extended its research
    collaboration agreement with The Johns Hopkins University School
    of Medicine directed to the discovery and validation of
    biomarkers in human subjects, including but not limited to
    clinical application of biomarkers in the understanding,
    diagnosis, and management of human diseases. Under the original
    agreement, which expired December 31, 2006, Ciphergen has
    an obligation to fund a total of $305,000, all of which had been
    accrued but not yet paid. Under the extended agreement, which
    begins January 1, 2007, Ciphergen has an obligation to fund
    a total of $600,000 for 2007. The first year contribution of
    $600,000 is non-cancelable. | 
|  | 
    |  |  | On October 4, 2006, the company entered into a one year
    research and development agreement with Katholieke Universiteit
    Leuven, Belgium directed at discovery, validation, and
    characterization of novel Biomarkers related to gynecologic
    disease. Under the terms of the agreement, Ciphergen will have
    exclusive rights to license discoveries made during the course
    of this collaboration. Ciphergen will contribute 45,000 Euros or
    $59,300 per year to fund sample collection at the
    University from patients undergoing evaluation of a persistent
    mass who undergo surgical intervention. The first year
    contribution of 45,000 Euros or $59,300 in non-cancelable. |

    |  |  |  | 
    | (5) |  | On November 13, 2006, in conjunction with the asset sale of
    the instrument business to Bio-Rad, Ciphergen also entered into
    a manufacturing and supply agreement with Bio-Rad. Under the
    terms of the agreement, Ciphergen will purchase a minimum of 10
    instruments and 30,000 ProteinChip arrays (arrays)
    during the first year, 13 instruments and 30,000 arrays during
    the second year, and 20 instruments and 30,000 arrays during the
    third year. The estimated cost to Ciphergen is $63,000 per
    instrument, and $20 per array. | 
 
    Off-Balance
    Sheet Arrangements
 
    As of December 31, 2006, we had no off-balance sheet
    arrangements that are reasonably likely to have a current or
    future material effect on our consolidated financial condition,
    results of operations, liquidity, capital expenditures or
    capital resources.

    Statements for a full description of recent accounting
    pronouncements, including the respective dates of adoption and

    |  |  | 
    | ITEM 7A. | QUANTITATIVE
    AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS | 
 
    We have classified our marketable securities as
    available-for-sale,
    and have, accordingly, recorded such securities on the balance
    sheet at fair value with unrealized gains and losses reported as
    a separate component of accumulated other comprehensive loss.
    These securities are not leveraged and are held for purposes
    other than trading.
 
    The following discussion about our market risk involves
    forward-looking statements. We have minimal exposure to market
    risk attributed changes in interest rates. We do not invest in
    derivative financial instruments.
 
    Interest
    Rate Sensitivity
 
    As of December 31, 2006, we had no short term investments.
    As of December 31, 2005, our only investment was a fixed
    rate annuity with a fair value of $2.2 million which was
    liquidated in February 2006. We believe that, in the near-term,
    we will maintain our available funds in money market accounts,
    or invest in short-term, highly liquid securities with original
    maturities of 90 days or less.
 
    The primary objective of our investment activities is to
    preserve principal, maintain proper liquidity to meet operating
    needs and maximize yields. Our investment policy, which has been
    approved by our Board of Directors, specifies credit quality
    standards for our investments and limits the amount of credit
    exposure to any single issue, issuer or type of investment. We
    may maintain our portfolio of cash equivalents, short-term
    investments and long-term investments in a variety of
    securities, including commercial paper, money market funds, and
    government and non-government debt securities, subject to our
    investment policy.
 
    Our exposure to market risk for changes in interest rates
    relates primarily to the increase or decrease in the amount of
    interest income we can earn on our available funds for
    investment. Our capital lease agreements are at fixed interest
    rates. We do not plan to use derivative financial instruments in
    our investment portfolio.
 
    Foreign
    Currency Exchange Risk
 
    Most of our revenue is realized in U.S. dollars. As a
    result, our financial results could be affected by factors such
    as changes in foreign currency exchange rates or weak economic
    conditions in foreign markets. Because most of our revenue is
    currently denominated in U.S. dollars, an increase in the
    value of the U.S. dollar relative to foreign currencies
    could make our products less competitive in foreign markets.
 
    The functional currency of Ciphergen Biosystems KK is the
    Japanese yen. Accordingly, the accounts of this operation were
    translated from the local currency to the U.S. dollar using
    the current exchange rate in effect at the balance sheet date
    for the balance sheet accounts, and using the average exchange
    rate during the period for revenue and expense accounts. The
    effects of translation were recorded as a separate component of
    stockholders equity. The
    
    40
 
    net tangible assets of our
    non-U.S. operations,
    excluding intercompany debt, were $1.6 million at
    December 31, 2006 . The accounts of all other
    non-U.S. operations
    are remeasured to the U.S. dollar, which is the functional
    currency. Accordingly, all monetary assets and liabilities of
    these foreign operations are translated into U.S. dollars
    at current period-end exchange rates, and non-monetary assets
    and related elements of expense are translated using historical
    rates of exchange. Income and expense elements are translated to
    U.S. dollars using average exchange rates in effect during
    the period. Gains and losses from the foreign currency
    transactions of these subsidiaries are recorded as other income
    (expense), net in the statement of operations.
 
    In 2004, we entered into foreign currency contracts to manage
    the volatility of currency fluctuations as a result of an
    intercompany loan of approximately $1.0 million,
    denominated in yen, to our subsidiary in Japan. The effect of
    exchange rate changes on the forward exchange contracts largely
    offset the effect of exchange rate changes on the intercompany
    loan. As of December 31, 2004, there were no forward
    contracts outstanding and none were entered into during 2005.
    Net realized foreign currency gains and losses related to
    foreign currency forward contracts were not material for the
    year ended December 31, 2004, and there were no such gains
    or losses in the year ended December 31, 2005. Although we
    will continue to monitor our exposure to currency fluctuations,
    we cannot provide assurance that exchange rate fluctuations will
    not harm our business in the future.

    REPORT OF
    INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
    In our opinion, the consolidated financial statements listed in
    the index appearing under Item 15(a) (1), present fairly,
    in all material respects, the financial position of Ciphergen
    Biosystems, Inc. and its subsidiaries at December 31, 2006
    and 2005, and the results of their operations and their cash
    flows for each of the three years in the period ended
    December 31, 2006 in conformity with accounting principles
    generally accepted in the United States of America. In
    addition, in our opinion, the financial statement schedule
    listed in the index appearing under Item 15(a)
    (2) presents fairly, in all material respects, the
    information set forth therein when read in conjunction with the
    related consolidated financial statements. These financial
    statements and financial statement schedule are the
    responsibility of the Companys management. Our
    responsibility is to express an opinion on these financial
    statements and financial statement schedule based on our audits.
    We conducted our audits of these statements in accordance with
    the standards of the Public Company Accounting Oversight Board
    (United States). Those standards require that we plan and
    perform the audit to obtain reasonable assurance about whether
    the financial statements are free of material misstatement. An
    audit of financial statements includes examining, on a test
    basis, evidence supporting the amounts and disclosures in the
    financial statements, assessing the accounting principles used
    and significant estimates made by management, and evaluating the
    overall financial statement presentation. We believe that our
    audits provide a reasonable basis for our opinion.
 
    As discussed in Note 1 to the consolidated financial
    statements, the Company changed the manner in which it accounts
    for stock-based compensation in 2006.
 
    The accompanying 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 and
    negative cash flows from operations and has a net capital
    deficiency that raise substantial doubt about its ability to
    continue as a going concern. Managements 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. | Organization
    and Summary of Significant Accounting Policies | 
 
    The
    Company
 
    Ciphergen Biosystems, Inc. (the Company or
    Ciphergen) is dedicated to the discovery,
    development and commercialization of specialty diagnostic tests
    that provide physicians with information with which to manage
    their patients care and that improve patient outcomes. We intend
    to use translational proteomics, which is the process of
    answering clinical questions by utilizing advanced protein
    separation tools to identify and resolve variants of specific
    biomarkers, developing assays, and commercializing tests.
 
    Prior to the November 13, 2006 sale of our protein research
    tools and collaborative services business (instrument
    business) to Bio-Rad, Ciphergen developed, manufactured
    and sold
    ProteinChip®
    Systems for life science research. This core technology, which
    was patented, is Surface Enhanced Laser Desorption/Ionization
    (SELDI). The systems consist of ProteinChip Readers,
    ProteinChip Software and related accessories, which were used in
    conjunction with consumable ProteinChip Arrays. These products
    were sold primarily to biologists at pharmaceutical and
    biotechnology companies, and academic and government research
    laboratories. The Company also provided research services
    through its Biomarker Discovery
    Center®
    laboratories, and offered consulting services, customer support
    services and training classes to its customers and
    collaborators. As a result of the sale of the instruments
    business to Bio-Rad, Ciphergen did not record any sales
    subsequent to November 13, 2006 and will not generate
    substantial revenues until certain diagnostic tests are approved
    by the FDA and commercialized.
 
    The accompanying consolidated financial statements of the
    Company were prepared on a going concern basis, which
    contemplates the realization of assets and the satisfaction of
    liabilities in the normal course of business. The Company has
    incurred significant net losses and negative cash flows from
    operations since inception. At December 31, 2006, the
    Company had an accumulated deficit of $217.9 million.
    Management believes that currently available resources together
    with existing debt facilities will not be sufficient to fund the
    Companys obligations. The Companys ability to
    continue to meet its obligations and to achieve its business
    objectives is dependent upon, among other things, raising
    additional capital or generating sufficient revenue in excess of
    costs. At such time as the Company requires additional funding,
    the Company may seek to raise such additional funding from
    various sources, including the public equity market, private
    financings, sales of assets, collaborative arrangements and
    debt. If additional capital is raised through the issuance of
    securities convertible into equity, stockholders will experience
    dilution, and such securities may have rights, preferences or
    privileges senior to those of the holders of common stock or
    convertible senior notes. If the Company obtains additional
    funds through arrangements with collaborators or strategic
    partners, it may be required to relinquish its rights to certain
    technologies or products that it might otherwise seek to retain.
    There can be no assurance that the Company will be able to
    obtain such financing, or obtain it on acceptable terms. If
    Ciphergen is unable to obtain financing on acceptable terms, it
    may be unable to execute its business plan, it could be required
    to delay or reduce the scope of its operations, and it may not
    be able to pay off the convertible senior notes if and when they
    come due.
 
    The Companys inability to operate profitably and to
    consistently generate cash flows from operations, its reliance
    on external funding either from loans or equity, raise
    substantial doubt about the Companys ability to continue
    as a going concern.
 
    Basis
    of Presentation
 
    The accompanying consolidated financial statements have been
    prepared in conformity with accounting principles generally
    accepted in the United States of America and include the
    accounts of the Company and its subsidiaries. All intercompany
    transactions have been eliminated in consolidation. BioSepra
    S.A. was a wholly-owned subsidiary and was consolidated through
    November 30, 2004, at which time the Company sold BioSepra
    S.A., along with other assets related to its process
    chromatography business. The BioSepra business is reflected as a
    discontinued operation in the statement of operations.

    STATEMENTS  (Continued)
 
    Use of
    Estimates
 
    The preparation of consolidated financial statements in
    accordance with accounting principles generally accepted in the
    United States of America requires management to make estimates
    and assumptions that affect the reported amounts of assets and
    liabilities and 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.
 
    Certain
    Risks and Uncertainties
 
    The success of the Company depends on managements ability
    to anticipate and to respond quickly and adequately to
    technological developments in its industry, changes in customer
    requirements and changes in industry standards. Any significant
    delays in the development or introduction of new products or
    services could have a material adverse effect on the
    Companys business and operating results.
 
    The Company licenses certain technologies that will be used in
    products that are under development. An inability to retain such
    technology licenses could result in a material adverse effect to
    the Company. Additionally, some of the raw materials and
    components used in its products are from single-source
    suppliers. If the Company is unable to obtain such raw materials
    and components, its financial condition and operating results
    could be significantly impacted.
 
    Cash
    and Cash Equivalents
 
    The Company considers all highly liquid investments purchased
    with an original maturity of three months or less to be cash
    equivalents.
 
    Investments
 
    Management determines the appropriate classification of the
    Companys investments in marketable debt securities at the
    time of purchase, and re-evaluates this designation at each
    balance sheet date. At December 31, 2005, the Company
    classified all marketable securities as
    available-for-sale
    and carried them at fair value with unrealized gains or losses
    related to these securities included as a component of other
    comprehensive income (loss) until realized. At December 31,
    2006, the Company did not have any investments in marketable
    debt securities. The amortized cost of debt securities is
    adjusted for amortization of premiums and accretion of discounts
    to maturity, which is included in interest income. Realized
    gains and losses are determined using the specific
    identification method. The cost of securities sold is based on
    the specific identification method.
 
    The Companys short-term investment at December 31,
    2005 consisted of an investment in a fixed rate annuity. The
    annuity is not within the scope of SFAS 115,
    Accounting for Certain Investments in Debt and Equity
    Securities. However, fair value approximates its carrying
    value due to its short maturity. In February 2006, the Company
    liquidated this investment.
 
    The Companys investment objectives include the
    preservation of invested funds and liquidity of investments that
    is sufficient to meet cash flow requirements. Cash, cash
    equivalents and investments in debt securities are with high
    credit-quality financial institutions, commercial companies and
    government agencies in order to limit the amount of credit
    exposure.
 
    Fair
    Value of Financial Instruments
 
    The estimated fair value of financial instruments has been
    determined using available market information or other
    appropriate valuation methodologies. However, considerable
    judgment is required in interpreting market data to develop
    estimates of fair value; therefore, the estimates are not
    necessarily indicative of the amounts that could be realized or
    would be paid in a current market exchange. The effect of using
    different market assumptions

    estimation methodologies may be material to the estimated fair
    value amounts. The carrying amounts of certain of the
    Companys financial instruments including cash and cash
    equivalents, accounts receivable, accounts payable and accrued
    liabilities approximated fair value due to their short
    maturities. The carrying value of the capital leases
    approximated their fair value based on the borrowing rates
    currently available to the Company for loans with similar terms.
    The carrying value of the equipment financing loan and the
    long-term debt from the credit facility provided by Quest
    Diagnostics approximated their fair values based on discounting
    the future cash flows using applicable spreads to approximate
    current interest rates available to the Company. Convertible
    senior notes have an estimated fair value based on quoted market
    prices. The fair value of the convertible senior notes as
    compared to their book value was as follows (in thousands):

    Concentration
    of Credit Risk
 
    Financial instruments that potentially subject the Company to a
    concentration of credit risk consist of cash and cash
    equivalents, investments in marketable debt securities and
    accounts receivable. Most of the Companys cash and cash
    equivalents as of December 31, 2006 were deposited with
    financial institutions in the U.S. and exceeded federally
    insured amounts. The Company also maintains cash deposits with
    banks in Western Europe, Canada, China and Japan. The Company
    has not experienced any losses on its deposits of cash and cash
    equivalents. At December 31, 2006, the Company did not have
    any investments in marketable debt securities. At
    December 31, 2005, the Company had $2.2 million of
    investments in marketable debt securities.
 
    The Companys accounts receivable are derived from sales
    made to customers located in North America, Europe and Asia. The
    Company performs ongoing credit evaluations of its
    customers financial condition and generally does not
    require collateral. The Company maintains an allowance for
    doubtful accounts based upon the expected collectibility of
    accounts receivable. No customer accounted for 10% or more of
    revenue in 2004, 2005 or 2006.
 
    Inventories
 
    Inventories are stated at the lower of standard cost, which
    approximates cost on a
    first-in,
    first-out basis, or market value. Cost includes direct
    materials, direct labor, contracted manufacturing services and
    manufacturing overhead. Reserves for potentially excess and
    obsolete inventory are recorded based on managements
    analysis of inventory levels, planned changes in product
    offerings, sales forecasts and other factors.
 
    Property,
    Plant and Equipment
 
    Property, plant and equipment are stated at cost less
    accumulated depreciation and amortization. Depreciation and
    amortization are computed for financial reporting purposes
    principally using the straight-line method over the following
    estimated useful lives: machinery and equipment, 3-5 years;
    demonstration equipment, 2 years; computer equipment,
    development systems used for collaborations and software,
    3 years; furniture and fixtures, 5 years; buildings
    and leasehold improvements, the lesser of their economic life or
    the term of the underlying lease. The cost of repairs and
    maintenance is charged to operations as incurred. Gains and
    losses resulting from disposals of assets are reflected in the
    year of disposition.

    Goodwill
    and Other Intangible Assets
 
    Goodwill represented the excess of the purchase price over the
    estimated fair value of the tangible and intangible net assets
    acquired in the Companys acquisitions of IllumeSys
    Pacific, Inc. in 1997, Ciphergen Technologies, Inc. in 1998 and
    Ciphergen Biosystems KK in 2002 and 2004. Goodwill is reviewed
    for impairment at least annually and in the interim whenever
    events or changes in circumstances indicate that the carrying
    amount of goodwill may be impaired. In determining whether there
    is an impairment of goodwill, the estimated fair value of the
    reporting unit in which the goodwill is recorded is calculated
    using a discounted future cash flow method. The resulting fair
    value is then compared to the net book value of the reporting
    unit, including goodwill. If the net book value of a reporting
    unit exceeds its fair value, the amount of the impairment loss
    is measured by comparing the implied fair value of the reporting
    units goodwill with the carrying amount of that goodwill.
    To the extent that the carrying amount of a reporting
    units goodwill exceeds its implied fair value, a goodwill
    impairment loss is recognized. In connection with the
    November 13, 2006 sale of the instrument business to
    Bio-Rad, the remaining carrying amount of goodwill of $76,000
    was written off.
 
    Other intangible assets represented a technology license
    acquired in connection with the settlement of litigation in 2003
    which is stated at cost and was being amortized on a
    straight-line basis over its estimated useful life of
    17 years. Other intangible assets were reviewed for
    impairment whenever events or changes in circumstances indicate
    that the carrying amount of an asset may no longer be
    recoverable. In connection with the November 13, 2006 sale
    of the instrument business, there are no longer any intangible
    assets recorded on our balance sheet as the intangible assets
    were associated with the instrument business sold to Bio-Rad.
 
    Long-lived
    Assets
 
    Long-lived assets, such as property, plant and equipment and
    purchased intangible assets, are reviewed for impairment when
    events or changes in circumstances indicate the carrying amount
    of an asset may not be recoverable. Recoverability is measured
    by comparison of an asset groups carrying amount to future
    net undiscounted cash flows the asset group is expected to
    generate. If such assets are considered to be impaired, the
    impairment to be recognized is measured by the amount by which
    the carrying amount of the assets exceeds the projected
    discounted future net cash flows arising from the assets. As of
    December 31, 2006, the Company believes no such impairment
    existed. Other long-term assets consist primarily of the
    offering costs of the convertible senior notes and security
    deposits for the Companys leased facilities.
 
    Revenue
    Recognition
 
    Revenue from product sales, including systems, accessories and
    consumables is recognized upon product shipment, provided no
    significant obligations remain and collection of the receivables
    was reasonably assured. Revenue from shipping and handling is
    generally recognized upon product shipment, based on the amount
    billed to customers for shipping and handling. The related cost
    of shipping and handling is included in cost of revenue upon
    product shipment.
 
    Revenue from sales of separately priced software products is
    recognized when realized or realizable and earned, which is when
    the following criteria are met:
 
    |  |  |  | 
    |  |  | persuasive evidence of an agreement exists, | 
|  | 
    |  |  | the price is fixed or determinable, | 
|  | 
    |  |  | the product has been delivered, | 
|  | 
    |  |  | no significant obligations remain, and | 
|  | 
    |  |  | collection of the receivable is deemed probable. |

    NOTES TO

    STATEMENTS  (Continued)
 
    The Company generally includes a standard
    12-month
    warranty on its instruments and accessories in the form of a
    maintenance contract upon initial sale. The Company also sold
    separately priced maintenance (extended warranty) contracts,
    which were generally for 12 or 24 months, upon expiration
    of the initial maintenance contract. Coverage under both the
    standard and extended maintenance contracts is identical.
    Revenue for both the standard and extended maintenance contracts
    was deferred and recognized ratably over the maintenance
    contract term. Related costs were expensed as incurred. Factors
    that affected the Companys warranty costs included the
    number of installed units, historical and anticipated rates of
    warranty claims, and cost per claim. In connection with the
    November 13, 2006 sale of the instrument business, Bio-Rad
    assumed the rights and obligations under the warranty obligation
    and maintenance contracts.
 
    For revenue from Biomarker Discovery Center contracts and other
    consulting contracts, if elements were specifically tied to a
    separate earnings process, then revenue related to an element
    was recognized when the specific performance obligation
    associated with that element was completed. When revenues for an
    element were not specifically tied to a separate earnings
    process, they were recognized ratably over the term of the
    agreement. Revenue from Biomarker Discovery Center services and
    other consulting contracts were recognized at the completion of
    key stages in the performance of the service as described in
    Ciphergens agreement with the customer. Often there was
    only a single element, namely delivery of a scientific report
    upon completion of Ciphergens analysis of customer
    samples, in which case the Company recognized all the revenue
    upon the conclusion of the project when all deliverables have
    been provided to the customer. Revenue was deferred for fees
    received before earned. Ciphergens training was billed
    based on published course fees and the Company generally
    recognizes revenue as the training is provided to the customer.
    BioMarker Discovery contracts and other consulting contracts
    were transferred to Bio-Rad as part of the sale of the
    instrument business.
 
    For revenue arrangements with multiple elements that are
    delivered at different points in time (for example, where
    Ciphergen has delivered the hardware and software but is also
    obligated to provide services, maintenance
    and/or
    training), the Company evaluated whether the delivered elements
    have standalone value to the customer, whether the fair value of
    the undelivered elements was reliably determinable, and whether
    the delivery of the remaining elements was probable and within
    the Companys control. When all these conditions were met,
    the Company recognizes revenue on the delivered elements. If any
    one of these conditions is not met, the Company deferred the
    recognition of revenue until all these conditions were met or
    all elements had been delivered. Fair values for ongoing
    maintenance were based upon separate sales of renewals to other
    customers. Fair values for services, such as training or
    consulting, were based upon separate sales by the Company of
    those services to other customers.
 
    Research
    and Development Costs
 
    Research and development expenditures are charged to operations
    as incurred. Research and development costs consist primarily of
    payroll and related costs, materials and supplies used in the
    development of new products, and fees paid to consultants and
    outside service providers. Software development costs incurred
    in the research and development of new products are expensed as
    incurred until technological feasibility is established. To
    date, products and upgrades have generally reached technological
    feasibility and have been released for sale at substantially the
    same time.
 
    Advertising
    Costs
 
    The Company expenses advertising costs as incurred. Advertising
    costs were $87,000 in 2006, $285,000 in 2005, and $665,000 in
    2004.
 
    Stock-based
    Compensation
 
    Effective January 1, 2006, the Company adopted
    SFAS No. 123 (revised), Share-Based
    Payment (SFAS 123(R)), using the modified
    prospective transition method. Under this new standard, the
    Companys

    NOTES TO

    STATEMENTS  (Continued)
    estimate of compensation expense requires a number of complex
    and subjective assumptions, including the price volatility of
    Ciphergens common stock, employee exercise patterns
    (expected life of the options), future forfeitures and related
    tax effects. Prior to the adoption of SFAS 123(R), the
    Company accounted for stock option grants using the intrinsic
    value method, in accordance with APB Opinion No. 25,
    Accounting for Stock Issued to Employees
    (APB 25), and accordingly, recognized no
    compensation expense for stock option grants.
 
    Under the modified prospective approach, SFAS 123(R)
    applies to new awards and to awards that were outstanding on
    January 1, 2006 that are subsequently modified, repurchased
    or cancelled. Under the modified prospective approach,
    compensation cost recognized in 2006 includes compensation cost
    for all stock-based payments granted prior to, but not yet
    vested as of, January 1, 2006, based on the grant-date fair
    value estimated in accordance with the original provisions of
    SFAS 123, and compensation cost for all stock-based
    payments granted subsequent to January 1, 2006, based on
    the grant-date fair value estimated in accordance with the
    provisions of SFAS 123(R). Prior periods were not restated
    to reflect the impact of adopting the new standard.
 
    The value of each option grant was estimated on the date of
    grant using the Black-Scholes option pricing model in 2006, 2005
    and 2004 with the following weighted assumptions:

    The expected term of stock options represents the
    weighted-average period the stock options are expected to remain
    outstanding and is based on the observed and expected time to
    post-vesting exercise and post-vesting cancellations of options
    by employees. Upon the adoption of SFAS 123(R), the Company
    used a combination of historical and peer group volatility for a
    blended volatility in deriving its expected volatility
    assumption as allowed under SFAS 123(R) and
    SAB No. 107. Prior to January 1, 2006, the
    Company used the historical volatility. The selection of the
    blended volatility approach was based upon the Companys
    assessment that blended volatility is more representative of
    future stock price trends than just using historical or peer
    group volatility. The risk-free interest rate assumption is
    based upon observed interest rates appropriate for the term of
    the Companys stock options. The expected dividend
    assumption is based on the Companys history and
    expectation of dividend payouts.
 
    The stock-based compensation expense recognized in the
    consolidated statements of operations for the year ended
    December 31, 2006 is based on awards ultimately expected to
    vest and has been reduced for estimated forfeitures.
    SFAS 123(R) requires forfeitures to be estimated at the
    time of grant and revised, if necessary, in subsequent periods
    if actual forfeitures differ from those estimates. Forfeitures
    were estimated based on historical experience. In the
    Companys pro forma information required under
    SFAS 123(R)for the periods prior to January 1, 2006,
    the Company accounted for forfeitures as they occurred.
 
    As a result of adopting SFAS 123(R), the Companys net
    loss, and basic and diluted loss per share for the year ended
    December 31, 2006 would have been $1.6 million and
    $0.04 per share higher, respectively, than if it had
    continued to account for stock-based compensation under APB
    Opinion No. 25. The Company has a 100% valuation allowance
    recorded against its deferred tax assets. Therefore
    SFAS 123(R) had no effect on the income tax provision in
    the consolidated statement of operations or the consolidated
    statement of cash flows. Stock-based

    Prior to 2006, the Company accounted for its stock-based
    employee compensation arrangements using the intrinsic value
    method of accounting. Unearned compensation expense was based on
    the difference, if any, on the date of the grant between the
    fair value of the Companys stock and the exercise price.
    Unearned compensation was amortized and expensed using an
    accelerated method. The Company accounted for stock issued to

    Income
    Taxes
 
    The Company accounts for income taxes using the liability
    method. Under this method, deferred tax assets and liabilities
    are determined based on the difference between the financial
    statement and the tax bases of assets and liabilities using
    enacted tax rates in effect for the year in which the
    differences are expected to affect taxable income. A valuation
    allowance is established when necessary to reduce deferred tax
    assets to the amounts expected to be realized.
 
    Foreign
    Currency Translation
 
    The functional currency of Ciphergen Biosystems KK is the
    Japanese yen. Accordingly, all balance sheet accounts of this
    operation are translated into U.S. dollars using the
    current exchange rate in effect at the balance sheet date. The
    revenues and expenses of Ciphergen Biosystems KK are translated
    using the average exchange rates in effect during the period,
    and the gains and losses from foreign currency translation are
    recorded directly into a separate component of
    stockholders equity under the caption Accumulated
    other comprehensive loss.
 
    The functional currency of BioSepra S.A. was the Euro. Upon the
    completion of the sale of BioSepra on November 30, 2004,
    the cumulative translation adjustment relating to BioSepra was
    included in the determination of the gain on the sale.

    Recent
    Accounting Pronouncements
 
    In July 2006, the FASB issued FASB Interpretation No. 48,
    Accounting for Uncertainty in Income Taxes  an
    Interpretation of FASB Statement No. 109
    (FIN 48), which clarifies the accounting for uncertainty in
    tax positions. This Interpretation requires that we recognize in
    our financial statements the impact of a tax position if that
    position is more likely than not of being sustained on audit,
    based on the technical merits of the position. The provisions of
    FIN 48 are effective as of the beginning of The
    Companys 2007 fiscal year, with the cumulative effect, if
    any, of the change in accounting principle recorded as an
    adjustment to opening retained earnings. The Company is
    currently evaluating the impact of adopting FIN 48 on its
    consolidated financial statements.
 
    In September 2006, the FASB issued SFAS No. 157,
    Fair Value Measurements (SFAS 157).
    SFAS 157 defines fair value, establishes a framework for
    measuring fair value in accordance with generally accepted
    accounting principles and expands disclosures about fair value
    measurements. The provisions of SFAS 157 are effective for
    fiscal years beginning after November 15, 2007. The Company
    is currently evaluating the impact, if any, of the adoption of
    SFAS 157 will have on its consolidated financial statements.
 
    In September 2006, the SEC issued Staff Accounting
    Bulletin No. 108 (SAB 108) in order to
    eliminate the diversity of practice surrounding how public
    companies quantify financial statement misstatements.
    Traditionally, there have been two widely-recognized methods for
    quantifying the effects of financial statement misstatements:
    the roll-over method and the iron
    curtain method. The roll-over method focuses
    primarily on the impact of a misstatement on the income
    statement, including the reversing effect of prior period
    misstatements; but its use can lead to the accumulation of
    misstatements in the balance sheet. The iron-curtain
    method, on the other hand, focuses primarily on the effect of
    correcting the period-end balance sheet with less emphasis on
    the reversing effects of prior period errors on the income
    statement. The Company currently uses the
    iron-curtain method for quantifying identified
    financial statement misstatements. In SAB 108, the SEC
    staff established an approach that requires quantification of
    financial statement misstatements based on the effects of the
    misstatements on each of our financial statements and the
    related financial statement disclosures. This model is commonly
    referred to as a dual approach because it requires
    quantification of errors under both the iron curtain
    and the roll-over methods. SAB 108 permits
    existing public companies to initially apply its provisions
    either by (i) restating prior financial statements as if
    the dual approach had always been used or
    (ii) recording the cumulative effect of initially applying
    the dual approach as adjustments to the carrying
    values of assets and liabilities as of the beginning of the
    current fiscal year with an offsetting adjustment to the opening
    balance of retained earnings in the year of adoption. Use of the
    cumulative effect transition method requires
    detailed disclosure of the nature and amount of each individual
    error being corrected through the cumulative adjustment and how
    and when it arose. The provisions of SAB 108 must be
    applied to annual financial statements no later than the first
    fiscal year ending after November 15, 2006. Upon adoption,
    there was no impact on the Companys consolidated financial
    statements or related disclosures.

    Alliance with Quest Diagnostics | 
 
    On July 22, 2005, the Company entered into a strategic
    alliance agreement with Quest Diagnostics covering a three year
    period during which the parties will strive to develop and
    commercialize up to three diagnostic tests. Pursuant to the
    agreement, Quest Diagnostics will have the non-exclusive right
    to commercialize these tests on aworldwide basis, with exclusive
    commercialization rights in territories where Quest Diagnostics
    has a significant

    presence for up to five years following commercialization. As
    part of the strategic alliance, there is a royalty arrangement
    under which Quest Diagnostics will pay royalties to Ciphergen
    based on fees earned by Quest Diagnostics for applicable
    diagnostics services, and Ciphergen will pay royalties to Quest
    Diagnostics based on Ciphergens revenue from applicable
    diagnostics products. To date, no such royalties have been
    earned by either party. Quest Diagnostics and Ciphergen have
    also entered into a supply agreement under which Ciphergen will
    sell instruments and consumable supplies to Quest Diagnostics to
    be used for performing diagnostics services which Ciphergen will
    purchase from Bio-Rad under its manufacturing and supply
    agreement (see Note 12, Commitments and
    Contingencies). In addition, for an aggregate purchase
    price of $15 million, Quest Diagnostics purchased
    6,225,000 shares of Ciphergens common stock, or
    approximately 17.4% of shares outstanding after the transaction,
    and a warrant having a term of five years to purchase up to an
    additional 2,200,000 shares for $3.50 per share. The
    warrant was valued at approximately $2.2 million based on
    the fair value as determined by a Black-Scholes model using the
    following assumptions: risk-free interest rate, 4.04%; expected
    life, 5 years; expected volatility 69%. Quest Diagnostics
    also agreed to loan Ciphergen up to $10 million with
    interest accrued at the prime rate plus 0.5% and paid monthly,
    solely to fund certain development activities related to the
    strategic alliance. Borrowings may be made by Ciphergen in
    monthly increments of up to approximately $417,000 on the last
    day of each month during the first two years of the strategic
    alliance, and at December 31, 2006, such borrowings
    amounted to $7.1 million. This loan, collateralized by
    certain intellectual property of Ciphergen, will be forgiven
    based on Ciphergens achievement of certain milestones
    related to development, regulatory approval and
    commercialization of certain diagnostic tests. Should the
    Company fail to achieve these milestones, the outstanding
    principal amount of any such loans will become due and payable
    on July 22, 2010. From the inception of the strategic
    alliance through December 31, 2006, the Company had spent
    approximately $7.1 million of the loan proceeds on in-house
    research and development, as well as collaborations with others,
    directed towards achieving the milestones.

    | 5. | Purchase
    of Additional Ownership Interest in Ciphergen Biosystems
    KK | 
 
    In January 1999, the Company formed Ciphergen Biosystems KK as a
    joint venture with Sumitomo Corporation to distribute the
    Companys products in Japan. On March 23, 2004, the
    Company acquired Sumitomos remaining interest in Ciphergen
    Biosystems KK, bringing its total ownership to 100%. The Company
    paid $1.0 million in cash. Acquisition costs were
    immaterial. The acquisition was accounted for using the purchase
    method of accounting.
 
    The total purchase price was allocated to the estimated fair
    value of assets acquired and liabilities assumed as follows (in
    thousands):
 
    |  |  |  |  |  | 
| 
    Tangible net assets acquired:

    The amount of the purchase price in excess of the net assets
    acquired was recorded as goodwill. We performed annual
    impairment tests through 2004 and determined that no impairment
    had occurred. Due to Ciphergen Biosystems KKs lower than
    expected operating results and cash flows throughout 2005 and
    based on revised forecasted results, a goodwill impairment loss
    of $2.5 million was recorded in the fourth quarter of 2005.
    The fair value of Ciphergen Biosystems KK was estimated using
    expected discounted cash flows.

    Sale of Instrument Business | 
 
    On November 13, 2006, Ciphergen completed the sale to
    Bio-Rad Laboratories, Inc. (Bio-Rad) of the
    Companys protein research tools and collaborative services
    business (the instrument business), which includes
    the Companys SELDI technology,
    ProteinChip®
    arrays and accompanying software through an asset sale
    transaction (the Asset Sale). Pursuant to the terms
    of the Asset Sale entered into with Bio-Rad on August 14,
    2006, Bio-Rad paid the Company approximately $16 million in
    cash at the closing of the transaction. An additional
    $4.0 million of contingent cash consideration includes
    $2.0 million, subject to certain adjustments, to be held in
    escrow as security for certain obligations of the Company for
    three years following the closing, and $2.0 million as a
    holdback amount to be held by Bio-Rad until the issuance of a
    re-examination certificate confirming a SELDI patent. (See
    Note 22 Subsequent Events, of the Notes to
    Consolidated Financial Statements).

    On November 13, 2006, Bio-Rad and Ciphergen entered into a
    Stock Purchase Agreement (the Purchase Agreement)
    for the private sale of shares of the Companys common
    stock to Bio-Rad for an aggregate purchase price of $3,000,000.
    The Purchase Agreement also provides for certain registration
    rights such that if the Company files a registration statement
    under the Securities Act of 1933, as amended, Bio-Rad may elect
    to include its shares in that registration, subject to various
    conditions. The purchase price of $0.972 per share was based on
    the average closing price for the 5 days preceding the
    Agreement on August 14, 2006. For accounting purposes, the
    3,086,420 shares purchased are valued at $1.17 per
    share, the closing price on November 13, 2006, the day the
    transaction closed. The resulting value of $3.611 million
    is allocated between common stock (3.1 million shares at
    $0.001 par value) and additional paid-in capital of
    $3.6 million.
 
    Subsequent to the November 13, 2006 completion of the Asset
    Sale, both Ciphergen and
    Bio-Rad
    recognized business activities on behalf of each party. As of
    December 31, 2006, Ciphergen owed to Bio-Rad a total of
    $1,571,000, which consisted of $1,511,000 of accounts receivable
    Ciphergen collected which belonged to Bio-Rad, $8,000 of
    operating expense invoices processed by Bio-Rad and reimbursable
    by Ciphergen to Bio-Rad, and $52,000 of other unbilled
    receivables from Bio-Rad. Similarly, Bio-Rad owed to Ciphergen a
    total of $619,000, which consisted of $174,000 of operating
    expense invoices processed by Ciphergen and reimbursable by
    Bio-Rad to Ciphergen, $200,000 of sales taxes on the sale of
    assets, and $245,000 of unbilled receivables from Bio-Rad.

    | 7. | Discontinued
    Operation-Sale of BioSepra Business | 
 
    On November 30, 2004, Ciphergen completed the sale to Pall
    Corporation of its wholly-owned French subsidiary, BioSepra
    S.A., along with selected other assets (together the
    BioSepra business). The sale of the BioSepra business
    generated net proceeds of approximately $27.0 million. An
    additional $1.0 million was placed in an interest-bearing
    escrow account for one year, after which that amount plus
    $21,000 of accrued interest was paid to Ciphergen and treated as
    an additional gain of $1,021,000 in 2005. This was partly offset
    by a $67,000 reduction of the gain on the sale of the BioSepra
    business for a post-closing adjustment in 2005, in accordance
    with the Asset

    The Company adopted SFAS 142 on January 1, 2002 for
    all goodwill and other intangible assets. As a result, goodwill
    is no longer amortized but rather tested for impairment at least
    annually and in the interim whenever circumstances indicate that
    goodwill may be impaired.
 
    The Company performed a transitional goodwill impairment
    assessment and noted no such impairment of goodwill. The Company
    also performed annual impairment tests from 2002 through 2006.
    In 2005, approximately $2.5 million of goodwill related to
    the Companys Japanese subsidiary was written off. In 2006,

    There are no longer any intangible assets recorded on our
    balance sheet. In connection with the asset sale of
    Ciphergens instrument business to Bio-Rad, Ciphergen
    sublicensed to Bio-Rad certain rights to the license rights for
    use outside of the clinical diagnostics field. Ciphergen
    retained exclusive rights to the license rights for use in the
    field of clinical diagnostics for a five year period, after
    which it will retain non-exclusive rights in that field. Bio-Rad
    agreed to pay the royalties due to MAS under the license rights,
    either directly to Ciphergen (to be paid to MAS) or directly to
    MAS, at its option.
 
    The sublicensed license relates to the May 28, 2003
    litigation settlement between Ciphergen and Molecular Analytical
    Systems, Inc. (MAS), LumiCyte, Inc.
    (LumiCyte), and T. William Hutchens whereby the
    Company acquired the undisputed exclusive rights granted to MAS
    under patents licensed from Baylor College of Medicine and the
    parties released all claims against each other. These patent
    rights refer to technology known as
    SELDI-TOF-MS,
    and provide the Company with an exclusive worldwide license and
    right to sublicense the technology and to commercialize any and
    all products, information and services derived from the
    technology without limitation.
 
    Furthermore, LumiCyte assigned all rights granted to it from MAS
    and related to the Baylor College of Medicine patents to the
    Company without restriction. As part of the settlement:
 
    (a) Ciphergen paid LumiCyte $3.0 million in cash;
 
    (b) Ciphergen issued to LumiCyte 1,250,000 shares of
    Ciphergen common stock which were valued at
    $7.8 million; and
 
    (c) Ciphergen agreed to pay license fees to MAS based on
    the revenues Ciphergen and its affiliates derive from the SELDI
    technology and recognize between February 21, 2003 and
    May 28, 2014, provided that such license fees will not
    exceed $1.0 million during calendar year 2003 or
    $10.0 million in the aggregate. Through December 31,
    2006, the Company had paid or accrued a total of
    $2.6 million in such license fees.
 
    The license rights were treated as an intangible asset that the
    Company purchased, and were amortized over its
    17-year
    useful life, from April 1997 to May 2014, using the straight
    line method. The cost was prorated between

    and Maintenance Contracts | 
 
    Until the sale of its instrument business to Bio-Rad, on
    November 13, 2006, Ciphergen had a direct field service
    organization that provides service for its products. The Company
    generally included a standard 12 month warranty on its
    ProteinChip Systems, ProteinChip Tandem MS Interfaces and
    accessories in the form of a maintenance contract upon initial
    sale, after which maintenance and support may be provided under
    a separately priced contract or on an individual call basis. The
    Company substituted a maintenance contract in place of a
    standard
    12-month
    warranty on its instruments and accessories upon initial sale.
    Ciphergen also sold separately priced maintenance (extended
    warranty) contracts, which are generally for 12 or
    24 months, upon expiration of the initial maintenance
    contract. Coverage under both the standard and extended
    maintenance contracts is identical. Revenue for both the
    standard and extended maintenance contracts is deferred and
    recognized on a straight line basis over the period of the
    applicable maintenance contract. Related costs are recognized as
    incurred.
 
    Changes in product warranty obligations, including separately
    priced maintenance obligations, during the years ended

    7.0% Convertible
    Senior Notes Due 2011
 
    On November 15, 2006, the Company closed the sale of
    $16,500,000 of Convertible Senior Notes due September 1,
    2011(the New Notes). Offering costs were $104,000
    and fees of $514,500, which were paid on behalf of the debt
    holders, were recorded as debt discount on the New Notes. Fees
    paid on behalf of debt holders included the fair value of two
    warrants issued to underwriters to purchase a total of
    200,000 shares of common stock at $1.26 per share. The
    warrant was valued at approximately $140,000 based on the fair
    value as determined by a Black-Scholes model using the following
    assumptions:a risk free interest rate of 4.75%, 5
    year contractual life, and 88% volatility rate. Interest on
    the notes is 7.0% per annum on the principal amount,
    payable semiannually on March 1 and September 1 of
    each year, beginning March 1, 2007. The New Notes were sold
    pursuant to separate exchange and redemption agreements between
    the Company and each of Highbridge International LLC, Deerfield
    International Limited, Deerfield Partners, L.P., Bruce Funds,
    Inc. and Professional Life & Casualty, each holders of
    the Companys existing 4.50% Convertible Senior Notes
    due September 1, 2008 ( the Old Notes),
    pursuant to which holders of an aggregate of $27.5 million
    of the Old Notes agreed to exchange and redeem their Old Notes
    for an aggregate of $16.5 million in aggregate principal
    amount of the New Notes and $11.0 million in cash, plus
    accrued and unpaid interest on the Old Notes of
    $0.3 million through and including the day prior to the
    Closing. The transaction was treated as a debt extinguishment
    and accordingly, $613,000 of unamortized prepaid offering costs
    and $868,000 of unamortized debt discount related to the Old
    Notes were charged to expense as loss on extinguishment of debt.
    Offering costs and debt discount related to the New Notes will
    be amortized to interest expense using the effective interest
    method. Amortization expense in 2006 for the New Notes was
    $15,000.
 
    The Company issued the New Notes pursuant to an indenture, dated
    November 15, 2006, between the Company and U.S. Bank
    National Association, as Trustee. Following the Closing,
    $2.5 million in aggregate principal amount of the Old Notes
    remain outstanding.
 
    The New Notes are unsecured senior indebtedness of the Company
    and bear interest at the rate of 7.00% per annum, which may
    be reduced to 4.00% per annum if the Company receives
    approval or clearance for commercial sale of any of its ovarian
    cancer tests by the U.S. Food and Drug Administration.
    Interest is payable on March 1 and September 1 of each
    year, commencing March 1, 2007. The effective interest rate
    is 7.13% per annum.
 
    The New Notes are convertible at the option of each Holder, at
    any time on or prior to the close of business on the business
    day immediately preceding September 1, 2011, into shares of
    the Companys common stock at a conversion price of
    $2.00 per share, equivalent to a conversion rate equal to
    500 shares of common stock per $1,000 principal of the New
    Notes, subject to adjustment in certain circumstances. If a
    Holder converts all or any portion of its Notes prior to
    October 31, 2008, upon such conversion, in addition to the
    Common Stock such Holder would receive, the Holder will be
    entitled to receive with respect to each Note so converted an
    amount in cash equal to the difference of (i) the amount of
    all interest that the Company would be required to pay on such
    Note from the date of the indenture through October 31,
    2008 and (ii) the amount of interest actually paid on such
    Note by the Company prior to the time of conversion.
 
    Holders of the New Notes have the option to require the Company
    to repurchase the New Notes under certain circumstances,
    including at any time after September 1, 2009, if the
    Company has not received approval or clearance for commercial
    sale of any of its ovarian cancer test by the FDA. The Company
    may redeem the notes at its option, in whole or in part, at any
    time on or after September 1, 2009 at specified redemption
    prices plus accrued and unpaid interest; provided that the notes
    will be redeemable only if the closing price of the stock equals
    or exceeds equals or exceeds 200% of the conversion price then
    in effect for at least 20 trading days within a period of 30
    consecutive trading days ending on the trading day before the
    date of the notice of the optional redemption. The
    8,250,000 shares that could be issued if all convertible
    senior notes were converted into common stock have not been
    included in the calculation of loss per share, as these
    potential common shares are antidilutive. Upon a change of
    control, each holder of the notes may require the Company to
    repurchase some or all of the notes at specified

    redemption prices, plus accrued and unpaid interest. The
    debenture contains a put option that entitles the holder to
    require the Company to redeem the debenture at a price equal to
    105.0% of the principal balance upon a change in control of the
    Company.
 
    The notes and common stock issuable upon conversion of the notes
    were registered with the U.S. Securities and Exchange
    Commission on
    Form S-3
    on December 15, 2006, and at December 31, 2006 all
    notes remained issued and outstanding
 
    4.5% Convertible
    Senior Notes Due 2008
 
    On August 22, 2003, the Company closed the sale of
    $30.0 million of convertible senior notes due
    September 1, 2008. Offering costs were approximately
    $1.9 million. Interest on the notes is 4.5% per annum
    on the principal amount, payable semiannually on March 1
    and September 1, beginning March 1, 2004. The
    effective interest rate is 5.85% per annum. The notes are
    convertible, at the option of the holder, at any time on or
    prior to maturity of the notes into shares of the Companys
    common stock initially at a conversion rate of
    108.8329 shares per $1,000 principal amount of the notes,
    which is equal to a conversion price of approximately
    $9.19 per share. The conversion price, and hence the
    conversion rate, is subject to adjustment upon the occurrence of
    certain events, such as stock splits, stock dividends and other
    distributions or recapitalizations. Because the market value of
    the stock rose above the conversion price between the day the
    notes were priced and the closing date, the Company recorded a
    discount of $2,677,000 related to the intrinsic value of the
    beneficial conversion feature resulting from this price change
    and the fact that the initial purchaser of the notes was not
    required to purchase the notes until the closing date.
    Immediately after the closing, Ciphergen common stock had a
    market price of $10.01 per share, or $0.82 per share
    higher than the conversion price. The value of the beneficial
    conversion feature was determined by multiplying this difference
    in the per share price of Ciphergens common stock by the
    3,264,987 underlying shares. This amount will be amortized to
    interest expense using the effective interest method over the
    five-year term of the notes, or shorter period in the event of
    conversion of the notes. Amortization in 2006, 2005 and 2004
    amounted to $473,000, $535,000 and $536,000, respectively.
 
    The notes are the Companys senior unsecured obligations
    and rank on parity in right of payment with all of the
    Companys existing and future senior unsecured debt and
    rank senior to the Companys existing and future debt that
    expressly provides that it is subordinated to the notes. The
    notes are also effectively subordinated in right of payment to
    the Companys existing and future secured debt, to the
    extent of such security, and to its subsidiaries
    liabilities. The indenture does not limit the incurrence by the
    Company or its subsidiaries of other indebtedness.
 
    The Company may redeem the notes at its option, in whole or in
    part, at any time on or after September 1, 2006 at
    specified redemption prices plus accrued and unpaid interest;
    provided that the notes will be redeemable only if the closing
    price of the stock equals or exceeds 150% of the conversion
    price then in effect for at least 20 trading days within a
    period of 30 consecutive trading days ending on the trading day
    before the date of the notice of the redemption. The shares that
    could be issued if all convertible senior notes were converted
    into common stock have not been included in the calculation of
    loss per share as these potential common shares are
    antidilutive. Upon a change of control, each holder of the notes
    may require the Company to repurchase some or all of the notes
    at specified redemption prices, plus accrued and unpaid
    interest. The debenture contains a put option that entitles the
    holder to require the Company to redeem the debenture at a price
    equal to 105.0% of the principal balance upon a change in
    control of the Company. The Company does not anticipate that the
    put option will have significant value because no change of
    control is currently contemplated.
 
    The notes and common stock issuable upon conversion of the notes
    were registered with the U.S. Securities and Exchange
    Commission on
    Form S-3
    on October 8, 2003, and at December 31, 2006.
    Following the closing of the November 15, 2006 sale of
    $16,500,000 of Convertible Senior Notes due September 1,
    2011, holders of an aggregate of $27.5 million of the Old
    Notes agreed to exchange and redeem their Old Notes for an
    aggregate of $16.5 million in aggregate principal amount of
    the New Notes and $11.0 million in cash. Therefore, the
    remaining $2.5 million in aggregate principal amount of the
    Old Notes remain outstanding.

    equipment purchases through this facility at an annual interest
    rate of 7.48%, repayable in monthly installments over
    36 months from the date of each drawdown under the

    respectively.
 
    Capital
    Leases
 
    As of December 31, 2006, The Company no longer held any
    capital lease agreements. Any agreements, pertaining to certain
    machinery and equipment in Japan under capital lease agreements
    with Sumitomo Corporation and other independent finance

    Operating
    Leases
 
    The Company leases various equipment and facilities to support
    its worldwide manufacturing, research and development, Biomarker
    Discovery Center, and sales and marketing activities. Total rent
    expense under all leases was $3,421,000, $3,825,000 and
    $3,685,000 in the years ended December 31, 2006, 2005 and
    2004, respectively. The Company leases its Fremont facility
    under a non- cancelable operating lease that expires on
    July 31, 2008. The lease provides for escalations of lease
    payments of approximately 4% per year and is recognized as
    rent expense on a straight line basis.
 
    As of December 31, 2006, future minimum payments under
    non-cancelable operating leases were as follows (in thousands):

    Product
    Development Agreement with a Customer
 
    In the third quarter of 2005, the Company sold nine ProteinChip
    Systems to one customer for $601,000. The Company also entered
    into a product development agreement with this same customer,
    whereby the customer will develop for Ciphergen a specific new
    product and Ciphergen may pay the customer up to $500,000 based
    on the customers attainment of specified development
    milestones. Under this agreement, Ciphergen paid this customer
    $300,000 of development fees during 2005. This was recorded,
    following EITF
    01-9,
    Accounting for Consideration Given by a Vendor to a
    Customer (Including a Reseller of the Vendors
    Products), as a reduction to revenue, resulting in net
    revenue from this customer of approximately $301,000 in 2005.
    This constituted approximately 2% of products revenue and 1% of
    total revenue for 2005. No additional payment was made in 2006.
    With the sale of the instrument business to Bio-Rad, the product
    development agreement was also transferred to Bio-Rad.
 
    Non-Cancelable
    Collaboration Obligations
 
    On October 3, 2005, the Company entered into a two year
    research and license agreement with University College London
    and UCL BioMedica Plc. (together, UCL) to utilize
    Ciphergens suite of proteomic solutions (Deep
    Proteometm,
    Pattern
    Tracktm
    Process and
    ProteinChip®
    System) to further UCLs ongoing research in ovarian cancer
    and breast cancer. Under the terms of the agreement, Ciphergen
    has exclusive rights to license intellectual property resulting
    from discoveries made during the course of this collaboration
    for use in developing, manufacturing and selling products and
    services utilizing the intellectual property. Additionally,
    Ciphergen will contribute approximately $2.1 million in
    cash and $652,000 in the form of Ciphergen equipment, software,
    arrays and consumable supplies as requested by UCL, valued at
    Ciphergens list selling price, to cover part of the costs
    incurred by UCL specifically for this research program.
    $1.1 million of the cash obligation is to be paid in the
    first year of the agreement and is non-cancelable. The remainder
    is to be paid in the second year of the agreement and is
    cancelable with three months advance notice. As of
    December 31, 2006, the Company had expensed $1,389,000, of
    which $57,000 represented the Companys cost for the arrays
    and consumables it had provided.
 
    On October 13, 2006, the company entered into a two year
    research and collaboration agreement with The Ohio State
    University Research Foundation directed at discovery,
    purification, identification
    and/or
    validation of Biomarkers related to thrombotic thrombocytopenic
    purpura and production of associated technology. Under the terms
    of the agreement, Ciphergen will have exclusive rights to
    license discoveries made during the course of this
    collaboration. Ciphergen will pay the financial contribution to
    the University in consideration for costs incurred by the
    University specifically used in furtherance of this research
    program for $149,500 in total during the first 15 months of
    the agreement. The contribution of $149,500 is non-cancelable.
    There is no financial contribution obligation for the remaining
    9 months of the agreement.
 
    On December 21, 2006, the company extended its research
    collaboration agreement through December 31, 2009 with The
    Johns Hopkins University School of Medicine directed to the
    discovery and validation of biomarkers in human subjects,
    including but not limited to clinical application of biomarkers
    in the understanding, diagnosis, and management of human
    diseases. Under the original agreement, which expired
    December 31, 2006, Ciphergen has an outstanding obligation
    to pay $305,000, which had been accrued and charged to research
    and development expense. Ciphergen paid $685,000 of
    collaboration expenses to John Hopkins in 2006 and expensed them
    to research and development. Under the extended agreement, which
    is effective January 1, 2007, Ciphergen has an obligation
    to provide additional collaboration funding of $600,000 for

    Litigation
 
    On June 26, 2006, Health Discovery Corporation filed a
    lawsuit against us in the U.S. District Court for the
    Eastern District of Texas (Marshall Division), claiming that
    software used in certain of Ciphergens
    ProteinChip®
    Systems infringes on three of its United States patents. Health
    Discovery Corporation is seeking injunctive relief as well as
    unspecified compensatory and enhanced damages, reasonable
    attorneys fees, prejudgment interest and other costs. On
    August 1, 2006 Ciphergen filed an unopposed motion with the
    Court to extend the deadline for Ciphergen to answer or
    otherwise respond until September 2, 2006. Ciphergen filed
    its Answer and Counterclaim to the Complaint with the Court on
    September 1, 2006. On January 10, 2007, the court
    granted Ciphergens motion to transfer the case to the
    Northern District of California. The case is scheduled for a
    case management conference on April 27, 2007 in the
    Northern District of California. Given the early stage of this
    action, the Company cannot predict the ultimate outcome of this
    matter at this time.
 
 
    At December 31, 2006 and 2005, 5,000,000 shares of
    preferred stock were authorized, but no shares were issued or
    outstanding.
 
    The Company has adopted a Stockholder Rights Plan, the purpose
    of which is, among other things, to enhance the Boards
    ability to protect stockholder interests and to ensure that
    stockholders receive fair treatment in the event any coercive
    takeover attempt of the Company is made in the future. The
    Stockholder Rights Plan could make it more difficult for a third
    party to acquire, or could discourage a third party from
    acquiring, the Company or a large block of the Companys
    common stock. The following summary description of the
    Stockholder Rights Plan does not purport to be complete and is
    qualified in its entirety by reference to the Companys
    Stockholder Rights Plan, which has been previously filed with
    the Securities and Exchange Commission as an exhibit to a
    Registration Statement on
    Form 8-A.
 
    The rights issued pursuant to Ciphergens Stockholder
    Rights Plan will become exercisable the tenth day after a person
    or group announces acquisition of 15% or more of
    Ciphergens common stock or announces commencement of a
    tender or exchange offer the consummation of which would result
    in ownership by the person or group of 15% or more of the
    Companys common stock. If the rights become exercisable,
    the holders of the rights (other than the person acquiring 15%
    or more of Ciphergens common stock) will be entitled to
    acquire, in exchange for the rights exercise price, shares
    of Ciphergens common stock or shares of any company in
    which the Company is merged, with a value equal to twice the
    rights exercise price.

    Stock Option Plan
 
    The Company has no shares of common stock reserved for sale to

    Plan (the 1993 Plan). Under the 1993 Plan, options
    were granted at prices not lower than 85% and 100% of the fair
    market value of the common stock for nonstatutory and statutory
    stock options, respectively. All outstanding options under the
    1993 Plan are now fully vested, and unexercised options
    generally expire ten years from the date of grant. At
    December 31, 2006, no shares of common stock were subject
    to repurchase by the Company. Since the Companys initial
    public offering, no options have been granted under the 1993
    Plan. During 2004, 2005 and 2006, options for 30,923, 12,040 and
    18,250 shares were exercised, respectively. Options for
    47,672, 87,113, and 371,979 shares were canceled during
    2004, 2005 and 2006, respectively, and the shares reserved under
    the 1993 Plan were reduced by the same amount.

    640,199 shares were canceled. During 2005, options for
    2,727,000 shares were granted, options for 216 shares
    were exercised, and options for 1,319,471 shares were
    canceled. During 2006, options for 1,569,450 shares were

    options for 2,740,329 shares were canceled.
 
    During 2005, two executives terminated their employment with the
    Company. The vesting of a portion of ones stock options
    was accelerated, and the exercise periods for both were
    extended, allowing the executives to potentially purchase option
    shares that would otherwise have expired. The expense resulting
    from these changes was not material to the consolidated
    financial statements.
 
    On January 1, 2004, 2005 and 2006 an additional 1,400,000,
    900,000 and 1,300,000 shares were reserved for issuance

    During the years ended December 31, 2004, 2005 and 2006,
    the exercise prices of all options granted were equal to fair
    market value on the dates of grant. During the year ended
    December 31, 2006, the Company recorded $1.6 million
    of stock-based compensation related to stock options granted to
    employees.

    During the period from April 1997 through December 31,
    2004, the Company recorded $20.9 million of deferred
    stock-based compensation related to stock options granted to
    consultants and employees. For options granted to consultants,
    the Company determined the fair value of the options using the
    Black-Scholes option pricing model with the following
    assumptions: contractual lives of ten years; weighted average
    risk-free rate calculated using rates between 4.5% and 6.2%;
    expected dividend yield of zero percent; volatility of 75% and
    deemed values of common stock between $0.35 and $14.67 per
    share. No options have been granted to consultants since the
    Companys initial public offering in 2000. Deferred
    stock-based compensation expense was recognized in accordance
    with an accelerated amortization method, over the vesting
    periods of the related options, which are generally five years.

    On December 20, 2005, Ciphergens Board of Directors
    approved the accelerated vesting of all unvested and
    out-of-the-money
    stock options held by employees with an exercise price per share
    of $4.00 or higher. The accelerated vesting caused options
    previously awarded for the purchase of approximately
    1,035,000 shares of Ciphergens common stock,
    representing approximately 16% of total options outstanding, to
    vest and become exercisable immediately, subject to continued
    restrictions on sale. Of the 224 option grants subject to
    accelerated vesting, 27 are held by executive officers. Under
    APB No. 25 and FASB Interpretation No. 44,
    Accounting for Certain Transactions Involving Stock
    Compensation , the acceleration of the vesting of these
    options did not result in a compensation charge because the
    exercise prices of the affected options was greater than the
    closing price of our common stock on December 20, 2005.
 
    Warrants
 
    At December 31, 2004 no warrants remained outstanding.
    During 2005, a warrant to purchase 2.2 million shares of
    Ciphergen common stock at $3.50 per share was issued to
    Quest Diagnostics as part of the Companys strategic
    alliance with Quest Diagnostics (See note 2,
    Strategic Alliance with Quest Diagnostics) . During
    2006, two warrants to purchase 100,000 shares each of
    Ciphergen common stock for a total of 200,000 shares, were
    issued to Oppenheimer & Co., Inc. for $1.26 per
    share. Fees paid on behalf of the debt holders were recorded as
    a discount on the New Notes. Fees paid on behalf of debt holders
    included the fair value of two warrants issued to underwriters
    to purchase a total of 200,000 shares of common stock at
    $1.26 per share. Fair value was determined by the Black
    Scholes method of valuation using a risk free interest rate of
    4.75%, 5 year contractual life, and 88% volatility rate.
    These warrants were valued at approximately $140,000. (See
    Note 11 Long-term Debt and Capital Leases). At
    December 31, 2006, all of the aforementioned warrants
    remained outstanding.
 
    Employee
    Stock Purchase Plan
 
    In April 2000, the stockholders approved the 2000 Employee Stock
    Purchase Plan, under which eligible employees may purchase
    common stock of the Company through payroll deductions.
    Purchases are made semi-annually at a price equal to the lower
    of 85% of the closing price on the applicable offering
    commencement date or 85% of the closing price at the end of the
    purchase period. At December 31, 2006, the Company had
    226,207 shares of common stock reserved for purchase by
    employees under this Plan. During 2004, 2005 and 2006, purchases
    of 306,209, 263,542, and 110,291 shares, respectively, were
    made under this Plan.
 
    On January 1, 2004, 2005 and 2006 an additional 290,795,
    180,000 and 170,000 shares, respectively, were reserved for
    purchase under the 2000 Employee Stock Purchase Plan. On
    June 3, 2004, the stockholders approved an additional
    250,000 shares to be reserved for this Plan.
 
 
    The Company accounts for income taxes using the liability
    method. Under this method, deferred tax assets and liabilities
    are determined based on the difference between the financial
    statement and tax bases of assets and

    allowances are established when necessary to reduce deferred tax
    assets to the amounts expected to be realized.
 
    In 2006, 2005, and 2004, the Company has incurred income tax
    liabilities primarily in France and Japan, as well as in most of
    the other countries outside the U.S. in which it operates.
    The Companys provision for income taxes was due to current
    foreign income taxes, which were $152,000, $7,000, and $172,000
    for the years ended December 31, 2006, 2005 and 2004,
    respectively, including discontinued operations. Excluding
    discontinued operations, current foreign income taxes were an
    expense of $152,000, $7,000, and $109,000 for the years ended
    December 31, 2006, 2005 and 2004, respectively.
 
    Based on the available objective evidence, management believes
    it is more likely than not that the net deferred tax assets
    related to the Companys operations will not be fully
    realizable. Accordingly, the Company has provided a full
    valuation allowance against its net deferred tax assets at
    December 31, 2006.

    Comprehensive loss generally represents all changes in
    stockholders (deficit) equity except those resulting from
    investments or contributions by stockholders. The only component
    of comprehensive loss that is excluded from the net loss is the
    Companys cumulative translation adjustments.
 
 
    Basic net loss per share is computed by dividing net loss for
    the period by the weighted average number of common shares
    outstanding during the period. Diluted net loss per share is
    computed by dividing the net loss for the period by the weighted
    average number of common and potential common shares outstanding
    during the period, if their effect is dilutive. Potential common
    shares include shares that could be issued if all convertible
    senior notes were converted into common stock, common stock
    subject to repurchase, common stock issuable under the
    Companys 1993 and 2000 Employee Stock Purchase Plans, and
    incremental shares of common stock issuable upon the exercise of
    outstanding stock options and warrants.

    Benefit Plans | 
 
    The Company maintains the Ciphergen Biosystems, Inc. 401(k)
    Savings Plan for its U.S. employees. The Plan allows
    eligible employees to defer up to 90%, subject to the Internal
    Revenue Service annual contribution limit, of their pretax
    compensation at the discretion of the employee. Under the Plan,
    the Company is not required to make Plan contributions. The
    Company had not made any contributions to the Plan as of
    December 31, 2006.
 
 
    On July 22, 2005, Quest Diagnostics purchased approximately
    17.4% of the Company. (See Note 2, Strategic Alliance
    with Quest Diagnostics.)
 
    On November 13, 2006, Bio-Rad purchased approximately 7.9%
    of the Company. (See Note 6, Gain on the Sale of the
    Instrument Business.)
 
    |  |  | 
    | 20. | Segment
    Information and Geographic Data | 
 
    Ciphergens revenue is derived from the sales of related
    products and services on a worldwide basis. The chief operating
    decision maker evaluates resource allocation not on a product or
    geographic basis, but rather on an enterprise-wide basis.
    Therefore, management has determined that Ciphergen operates in
    only one reportable segment, which is the protein research tools
    and collaborative services business.
 
    The following table reflects the results of the Companys
    sales to external customers by similar products and services for
    the years ended December 31, 2006, 2005 and 2004 (in
    thousands). Revenue from discontinued operations has been
    excluded.

    The Company sells its products and services directly to
    customers in North America, Western Europe and Japan, and
    through distributors in other parts of Europe and Asia and in
    Australia. Revenue for geographic regions reported below is
    based upon the customers locations and excludes revenue
    from discontinued operations. Long-lived assets, predominantly
    machinery and equipment, are reported based on the location of
    the assets.

    the same basis as the audited consolidated financial statements
    and includes all adjustments (consisting only of normal
    recurring adjustments, except for the non-recurring expense
    resulting from the litigation settlement) necessary to state

    The Companys United States Patent 6,734,022 (the 022
    patent) is currently under re-examination in the United States
    Patent and Trademark Office. The 022 patent is directed to
    a fundamental process of SELDI that involves capturing an
    analyte from a sample on the surface of a mass spectrometry
    probe derivatized with an affinity reagent, applying matrix and
    detecting the captured analyte by laser desorption mass
    spectrometry. In March 2007, the USPTO issued a final office
    action in the re-examination, rejecting all of the claims of the
    022 patent. The Company believes that the claims of the
    022 patent are valid. While the office action is
    designated final the Company has, under the USPTO
    rules, as much as 6 months to advocate for the patentability of
    the claimed invention with the patent examiners, after which the
    Company has recourse to appeal. The Company plans to respond to
    the final office action and if necessary to appeal the decision.
    If the USPTO does not issue a re-examination certificate
    confirming the patentability of all of the claims as originally
    issued in the 022 patent, or claims of equivalent scope,
    the Company will not be entitled to receive the $2,000,000
    holdback amount from Bio-Rad pursuant to the Asset Purchase
    Agreement between Ciphergen and Bio-Rad. Furthermore, if these
    claims are canceled or significantly narrowed in scope, the
    Company may be unable to block competitors from utilizing SELDI
    to develop diagnostic tests that involve detecting a single
    diagnostic biomarker, and the Companys  revenues may
    therefore be adversely affected.

    Evaluation of Disclosure Controls and
    Procedures.  Ciphergen evaluated its disclosure
    controls and procedures (as defined in Exchange Act
    Rule 13a-15(e))
    as of the end of the period covered by this Annual Report on
    Form 10-K,
    under the supervision and with the participation of the
    Companys principalexecutive and financial officers. Based
    on that evaluation, the Companys principal executive and
    financial officers concluded that the Companys disclosure
    controls and procedures are effective to ensure that information
    required to be disclosed in reports that we file or submit under
    the Exchange Act is recorded, processed, summarized and reported
    within the time periods specified in Securities and Exchange
    Commission rules and forms.
 
    There have been no changes in our internal control over
    financial reporting, as such term is defined in Exchange Act
    Rules 13a-15(f)
    and
    15d-15(f),

    Securities Dealers, Inc. Executive officers, directors and
    greater than ten percent (10%) stockholders are required by
    Commission regulation to furnish us with copies of all
