Background



Overview



Pharmaceutical and biotechnology companies are continually
challenged to develop and market increased numbers of drugs. This challenge has led to increased research and development spending and the development of a new research focus called genomics-based drug discovery. This new research effort involves
understanding the relationship between genes and the functions they regulate. An organisms genetic information, or genome, is comprised of deoxyribonucleic acid, or DNA molecules. DNA itself is comprised of four different chemical subunits
called nucleotide bases that are strung together in a precise sequence. Encoded within a DNA sequence are discrete sets of instructions, or genes, that collectively serve to regulate our biological processes by producing proteins. Alterations or
mutations in these gene sequences form the basis of many diseases.



Understanding the critical role that genes play in regulating biological processes and disease has led to efforts to obtain information on all the genes contained within the human genome and the genomes of other organisms.
International public and private genomics projects have generated vast amounts of data and identified many of the genes within the human genome. The human genome is believed to be comprised of approximately three billion nucleotide bases that
encode approximately 30,000 to 40,000 genes. Approximately 3,000 to 10,000 of these genes and the proteins these genes encode may have potential as drug targets and drug candidates. Seeking to capitalize upon the opportunity to discover new
drug targets, pharmaceutical, biotechnology and genomic companies are rapidly pursuing genomics-based drug discovery programs. We believe that a system that will enable a more rapid commercialization of these newly discovered genes and the proteins
these genes encode can be of significant value to drug manufacturers.



Genomics-based drug discovery generally consists of:



| |  |  | discovering and identifying DNA sequences that make up the genes within the genome;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | determining the function of the discovered genes so that their role in regulating biological processes and disease can be understood;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | using information on gene function and disease relevance to assess the value of a particular gene or its protein product as a target for drug discovery; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in the case of genes that are potential drug targets, utilizing high-volume chemistry and other drug discovery methods to target the relevant gene to produce a
commercially viable drug.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Pharmaceutical, biotechnology and academic researchers have performed the initial task of identifying genes. However, identifying the genes is only the first hurdle of several significant current impediments to genomics-based drug
discovery. The next key hurdles are determining gene function, identifying which genes can serve as viable drug targets and which proteins encoded by these genes can serve as viable drug candidates. Determining gene function with respect to a
biological process or disease is a complex undertaking that requires extensive and detailed physiological analysis.



Discovering Gene Function



The scientific community has attempted to find efficient methods of determining the functions of individual genes for several decades.
This process is particularly challenging for the pharmaceutical industry because drug development requires a very precise understanding of potential drug discovery targets. It is important that a pharmaceutical or biotechnology researcher
understands all the possible ramifications of targeting a gene or its associated protein with a drug, including any potentially serious side effects of drug administration.



The drug discovery and development process is an expensive, time-consuming and lengthy process. Before a gene
can be selected as a candidate for the drug discovery and development process, its complete functional role must be determined as thoroughly as possible. Determining whether a gene is a relevant target for drug



4

##### Table of Contents

discovery is a process termed target validation. Currently, researchers generally use the standard or genetic approaches to drug target
discovery and validation described below.



Standard Approach to Target Discovery and Validation



The objective of the standard approach to target discovery is to sort through the tens of thousands of gene sequences to find ones that can be analyzed using current techniques for determiningin
vivo biology, or the function of the gene in a living organism. Under the standard approach, researchers:



| |  |  | identify a gene sequence;
| | - |  | -------------------------



| |  |  | isolate and make an operational copy of the gene in order to facilitate physiological analysis of its function;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | find the tissues where the gene is active, or expressed, which may provide clues about the potential functional role of the gene;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | perform cell-based, or in vitro, experiments using potentially relevant cell types to define a potential role for the gene; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | conduct studies in a living mammal, or in vivo studies, to determine the role of the gene in a whole organism, a key step in providing confirmation of the
gene as a validated target for drug discovery.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The standard approach to target discovery is a time consuming, expensive and multi-staged process in which only a limited number of genes reach the final steps of the validation process. The lack of in vivo data early in this
process can lead to the selection of genes based on criteria that do not necessarily or accurately reflect their functions in a living organism. This can lead to significant wasted time, effort and expense in selecting genes that represent valid
targets.



Genetic Approach to Target Discovery
and Validation



Since the function of a gene
in an animal can vary widely from its function as determined by in vitro studies, it is preferable to obtain in vivo data at an early stage in the drug discovery process. To accomplish this, some pharmaceutical and biotechnology
companies have employed a genetic approach that initially uses non-mammalian organisms to determine in vivo function. Under the genetic approach, researchers:



| |  |  | choose a lower organism, such as a fly or worm, based on the compatibility of the organism with the specific organ system or function to be studied;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | create a functional mutation in the lower organism by using chemicals to produce a permanent genetic alteration that is reflected by an observable change in the
organism;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | identify the mutated gene responsible for the observed change;
| | - |  | --------------------------------------------------------------



| |  |  | find the equivalent gene in mammals; and
| | - |  | ----------------------------------------



| |  |  | conduct in vivo studies to determine the role of the gene in a whole organism, a key step in providing confirmation of the gene and the protein encoded by
that gene as a validated target or candidate for drug discovery.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The genetic approach to target discovery is subject to a number of limitations. Under the genetic approach, researchers randomly mutate the genome. This may result in the identification of genes with
interesting functions; however, these genes may not become valid drug targets because only certain subsets of genes are amenable to current drug discovery methods. In addition, since lower organisms are far less complex than mammals, they do not
have many of the mammalian genes and their corresponding physiological functions. Thus, while lower organisms can provide information on gene function similarity with humans, their ability to provide information concerning how genes control
mammalian physiology is limited. As a result, validation typically requires mammalian studies that are traditionally time-consuming and costly.

Determining
Mammalian Gene Function



During the past
decade, the preferred method for determining a genes function in mammals has been to disrupt, or knock out, the gene in a mouse and to assess the physiological, pathological and behavioral consequences of removing the gene from the animal. The
results of this analysis can determine the function and disease relevance of a particular gene and the potential of the gene and the protein encoded by that gene as a drug target or drug candidate.



Mice and humans are both higher mammals, and their genomes are
similar in size and gene content. Therefore, performing knockouts of genes in mice has advantages over studies in non-mammalian organisms for defining the function and disease relevance of human genes. Additionally, mice are one of the few mammals
for which approaches to genetic manipulation have been established. Because of the high degree of physiological and genetic similarity between mice and humans, the mouse gene knockout system has the potential to become an effective and widely
accepted model for target validation studies.



A
drawback of this model though has been the low-volume, high-cost and commercially unfeasible time-frames for production. Traditional approaches to create mouse knockouts allow a research team to create only a limited number of knockouts per year. As
a result, mouse knockouts have often been used as the last step of the target validation process, if at all.



Despite the time-frame and labor intensive nature of the process, the academic scientific community has adopted the mouse knockout as a
model for gene function studies. Information from these studies is often publicly available. However, this information is often fragmentary, difficult to obtain and is selectively and non-uniformly reported. In addition, when such information is
available, it can be difficult to cross-reference or compare using standardized medical/scientific vocabulary or to compare with pre-existing models of disease.



Collectively, these limitations have made mouse knockouts difficult to use as a first-line drug discovery
tool despite their utility in determining gene function.



Our
Solution



We have developed an integrated
target validation system that provides gene function information based on mouse knockouts at early stages of drug target discovery. Our solution moves directly from gene identification to determination of gene function in a mammalian organism on a
commercially viable scale. Through our high-throughput system, targets are more readily identified and made available to our pharmaceutical partners and customers.



We utilize proprietary molecular biology systems to more efficiently knock out genes in mice on a large scale
and conduct a detailed analysis of the resulting physiological, pathological and behavioral effects in these mice. As a result, we assess the function of the gene in a mammal that is closely related genetically and physiologically to humans.



We believe our technology platform and approach
offers significant advantages over the standard and genetic approaches, including:



| |  |  | INCREASING THE SCALE AND SPEED OF GENERATING MAMMALIAN GENE FUNCTION INFORMATION, DELIVERING FUNCTIONAL INFORMATION ON GENE TARGETS AND DISCOVERING POTENTIAL
SECRETED PROTEIN DRUG CANDIDATES.    For our DeltaBase product, we currently target, analyze and deliver detailed in vivo gene function information on approximately 250 different genes per year. Our proprietary
high-throughput gene knockout and analysis system can be scaled-up to greater capacity if we determine additional production is required.

| |  |  | REDUCING THE COST OF DETERMINING GENE FUNCTION, PROVIDING VALIDATED GENE TARGETS AND IDENTIFYING POTENTIAL SECRETED PROTEIN DRUG
CANDIDATES.    By providing a fully integrated target validation system as opposed to a multi-tier process, we believe we can reduce the number of steps and costs associated with the target validation process and the number of
parties to whom royalties must be paid. Through our DeltaBase database product, we provide our subscribers with information on gene function and the potential of genes as viable drug targets earlier in the drug discovery process than under the
standard or genetic approaches. We believe that early access to in vivo data allows selection of appropriate drug targets, increases efficiency and reduces costs by allowing our subscribers to focus on genes with high potential for successful
drug development. This information may allow our subscribers to eliminate non-viable targets from potential development earlier in the discovery process. Our target validation system may also increase the efficiency and reduce the costs associated
with our discovery of potential secreted protein drug candidates in our collaborative and our own internal secreted protein programs.

| |  |  | PRE-SELECTING COMMERCIALLY RELEVANT MAMMALIAN GENE TARGETS.    We have focused our target validation efforts on gene families that we believe
have the greatest potential for drug development. Worldwide genome sequencing efforts have identified many new members of the gene families currently targeted by the pharmaceutical and biotechnology industry, including over 2,500 members that
we have initially selected that may have relevance to disease and are potential targets of drug discovery efforts.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PROVIDING ACCESS TO KNOCKOUT MAMMALIAN ANIMAL MODELS.    The preclinical testing, or animal testing, of drugs has often been impeded by the lack
of animal models that can represent the human disease condition. We believe our target validation system can produce and deliver relevant knockout mouse models that are of interest to the pharmaceutical and biotechnology industries, as well as to
academic and research institutions. These knockout mouse models can be used for further research and development relating to gene function and disease analysis.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | ALLOWING OUR CUSTOMERS TO STORE, ACCESS, MANIPULATE AND ANALYZE GENE FUNCTION INFORMATION THAT WE GENERATE.    We have developed a proprietary
information technology infrastructure for the delivery, maintenance and use of the data we produce. We organize and deliver our data in a manner that we believe will provide simple and rapid accessibility. Additionally, our data is compatible with
standard computing tools used by the pharmaceutical and biotechnology industries.

intellectual property protection for our commercially relevant gene function discoveries and under certain of our programs, plan to grant our customers certain rights to use our intellectual property.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



In addition to our gene function database programs, we have
collaborative programs to discover novel, commercially relevant secreted proteins. Secreted proteins are proteins that play an important role in the formation, regulation, growth and maintenance of multi-cellular organisms. Examples of well-known
secreted proteins discovered by other companies include insulin, human growth hormone, or HGH, and erythropoeitin, or EPO. Using our core technology platforms, along with our other proprietary technologies, we have developed a secreted protein
program that identifies and defines the mammalian in vivo function of mammalian secreted proteins. Specifically, we have proven genetic technologies that allow us to more rapidly identify and knock out secreted proteins in mice. We believe
that our secreted protein discovery programs provide a foundation for developing and commercializing proprietary therapeutic protein products.



Our Strategy



Over the past six months we have undertaken significant cost reduction actions. These actions will reduce the number of employees from a
peak of approximately 450 in 2002 to approximately 150 by April 2003 and



7



---

##### Table of Contents

reduce the number of facilities from ten in 2002 to two facilities by April 2003 with the announced intention of having a single facility by
mid 2003. The remaining facility will be 132,000 square feet and includes state-of-the- art animal vivarium and laboratory space as well as housing our sales and administrative personnel. At the same time we have discontinued our internal drug
discovery efforts and have refocused our strategies and operations on providing drug discovery services to the biopharmaceutical industry utilizing our proprietary core mammalian in vivo transgenic technologies.



In April 2003, we secured a minimum commitment for $10 million
in equity capital from existing institutional investors to purchase preferred stock in a transaction referred to here in as the private placement. The private placement is subject to shareholder approval and the satisfaction of closing conditions.
In addition to the terms of the private placement, our stockholders will be asked to approve a number of other matters including a reverse stock split.



Under the terms of the private placement, the investors have agreed to purchase $10 million of preferred stock. The preferred stock is
convertible into common stock on a 1:1 basis. The preferred stock will be issued at a 25% discount to the five-day average closing common stock price for the period ending three days prior to closing. The preferred stock bears no dividend, has a
liquidation preference right equal to the amount invested in the preferred stock and standard anti-dilution protections. The terms of the preferred stock agreement include the right to appoint designees to a total of three seats on the Board of
Directors.



In connection with the private
placement, we have agreed to use reasonable best efforts, as soon as reasonably practicable after the closing of the private placement, to offer stockholders of record as of the last business day prior to the closing of the private placement (other
than the investors in such financing) non-transferable rights to purchase newly issued preferred stock at the same purchase price paid by the investors. The amount of preferred shares so offered to each stockholder would be sufficient to allow each
such stockholder to maintain the percentage ownership interest in Deltagen, held by each such stockholder as of the last business day prior to the closing of the private placement.



Our goal is to continue to be a leader in providing in vivo derived gene function information to
define the function and disease relevance of mammalian genes for the purpose of discovering and validating novel drug targets for the pharmaceutical and biotechnology industries. We believe our data will improve the speed, efficiency and
effectiveness of drug discovery, thereby benefiting our pharmaceutical partners and customers. As we have a limited operating history and an unproven business strategy, we cannot assure you that we will succeed in achieving our goals. The key
elements of our strategy include:



| |  |  | BECOMING THE MOST COMPREHENSIVE SOURCE OF MAMMALIAN INFORMATION ON GENE FUNCTION AND TARGET VALIDATION.    We intend to further expand our
current technology platforms and develop new programs and systems to increase the scale, scope and depth of our ability to determine mammalian gene function.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PURSUING THE DISCOVERY AND EARLY-STAGE DEVELOPMENT OF POTENTIAL SECRETED PROTEIN DRUG CANDIDATES THROUGH OUR COLLABORATIVE SECRETED PROTEIN
PROGRAM.    We plan to continue the development of our secreted protein discovery program in order to provide a pipeline of secreted proteins to serve as potential drug discovery candidates with our collaborative partners.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | FOCUSING ON THE COMMERCIAL NEEDS OF OUR CUSTOMERS.    We plan to deliver valuable gene function information to our customers and allow them to
concentrate on the drug discovery process downstream of target validation. By focusing our research process on target validation and obtaining functional information, we believe we provide our customers meaningful time and cost savings in their drug
discovery efforts.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PROVIDING ADDITIONAL IN-DEPTH ANALYSIS TO FURTHER VALIDATE AND CHARACTERIZE POTENTIAL DRUG TARGETS.    Utilizing our systems biology
approach, we will have the ability to utilize data generated from our platform of knockout animal models and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | pathophysiological analysis, disease challenge models and biochemical pathway analysis to further characterize and identify potential key
targets for the treatment of disease.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PROVIDING ACCESS TO KNOCKOUT MAMMALIAN ANIMAL MODELS.    The preclinical testing, or animal testing, of drugs has often been impeded by the lack
of animal models that can represent the human disease condition. We believe that our target validation system can produce and deliver relevant knockout mouse models that are of interest to the pharmaceutical and biotechnology industries, as well as
academic and research institutions. These knockout mouse models can be used for further research and development related to gene function and disease analysis.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | PROVIDING BREEDING SERVICES utilizing the capacity of our recently completed animal vivarium.
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | CONTINUING TO PURSUE INTELLECTUAL PROPERTY RIGHTS.    We are employing an intellectual property strategy to secure patent, trademark and
copyright protection for what we believe to be our commercially relevant inventions, products, and methods. Under certain programs and collaborations, we intend to offer our customers access to certain of our intellectual property rights.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Our Products and Programs



We have developed and plan to continue to develop
technologies, products and programs that elucidate the function and disease relevance of genes in mammalian organisms. We are developing, refining and expanding the following products and programs:



DeltaBase



Overview



DeltaBase is our proprietary database that provides
information, based on knockout mouse studies, on gene function for drug discovery. We created DeltaBase to be marketed to the pharmaceutical and biotechnology industries to help define the role that genes play in biological processes and disease. We
believe that DeltaBase is a valuable resource for mammalian gene function information.



DeltaBase has been expanding by the addition of approximately 250 different mammalian genes each year. Genes are selected for DeltaBase based on their potential to become useful drug targets. We
generate information on these genes by comprehensively analyzing knockout mice generated through our proprietary, gene knockout methods. Each knockout mouse undergoes a standardized, detailed and extensive analysis in order to determine the function
and role that a particular gene plays in the mouse. We believe that the body of gene function information delivered under DeltaBase provides an advantage to the drug discovery efforts of pharmaceutical and biotechnology companies by reducing the
time required for target validation.



Additionally, DeltaBase subscribers have access to the knockout mice used to generate this data. Access to these animals will allow DeltaBase subscribers to more rapidly pursue specific areas of interest.



DeltaBase Technologies



We designed DeltaBase to provide our subscribers with the
ability to compare resulting phenotypic and gene function data across hundreds of different mammalian genes from different gene families selected for their potential commercial relevance to drug discovery. In order to generate, analyze, store,
manipulate and deliver such large volumes of data and information, we have developed proprietary, high-volume, assembly-line methods to:



| |  |  | RAPIDLY AND EFFICIENTLY GENERATE LARGE NUMBERS OF KNOCKOUT MICE ANIMAL MODELS.    We utilize proprietary molecular biology systems to more
efficiently knock out genes in mice on a large scale. We are able to move directly from a small amount of gene sequence information
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

straight to the production of knockout mice and the determination of gene function. We have the capacity to analyze approximately 250
targeted gene knockouts per year for our DeltaBase program, which we believe is a significant improvement over historical, relatively limited production by others. This system can be scaled to meet market demand.



| |  |  | SELECT MAMMALIAN GENES AND GENE FAMILIES TO IDENTIFY POTENTIAL DRUG TARGETS.    In selecting the gene families for DeltaBase, we targeted those
that have demonstrated their value as drug development targets, have led to the commercialization of successfully marketed drugs and present potential additional drug development targets. The current gene families represented in DeltaBase include
the G-protein coupled receptors, ion channels and proteases. As part of the gene target selection process, we utilize information technology, statistical analysis and biological information systems to extract and analyze publicly available data on
the human genome to search for additional genes and gene families with potential commercial relevance to drug discovery efforts. This application of statistical and mathematical models to genetics is known as bioinformatics. To date, our
bioinformatics program has focused on an initial pipeline of over 2,500 potential targets for development under DeltaBase that we believe may be of interest to prospective pharmaceutical and biotechnology subscribers.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | EXTENSIVELY ANALYZE THE KNOCKOUT MICE GENERATED.    We have developed and employ large-scale assembly-line analysis programs that provide
detailed physiological and pathological data. This analysis is performed on all major tissues and organ systems within the mouse. Moreover, this analysis of the entire organism may provide information on possible side effects and toxicology profiles
associated with each gene and its function. We believe that the DeltaBase knockout mice can serve as efficient vehicles for the generation of additional complementary information and data on gene function which would be marketed as a separate
product.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | ACCURATELY AND EFFICIENTLY CAPTURE, STORE, MANIPULATE AND DELIVER DATA GENERATED FROM THE ANALYSES OF KNOCKOUT MICE.    DeltaBase subscribers
will have the ability to access, utilize and perform multifaceted analysis on the gene function data and information contained in DeltaBase. In addition, our proprietary information technology allows our customers to perform searches of the gene
function analyses contained in DeltaBase, obtain detailed scientific and pathology summaries of gene function findings and submit inquiries and questions to DeltaBase through a medical/scientific vocabulary search engine. To meet the needs of
DeltaBase subscribers, the data and information is readily exportable and can be manipulated by information technology tools and other databases widely employed in the pharmaceutical and biotechnology industries.

Marketing and Customer Agreements



As of the end of 2002, we had DeltaBase agreements with
GlaxoSmithKline, Merck, and Pfizer. Each of these agreements provides for payments aggregating approximately $15 million for non-exclusive access to information related to 750 genes selected for their biological interest that have been functionally
characterized and entered into DeltaBase. Under the current DeltaBase agreements, GlaxoSmithKline, Pfizer, and Merck have the right to access DeltaBase information on gene function based upon knockout mouse studies. As of December 31, 2002,
information related to 125-150 genes remain to be provided under these agreements.



During 2002, we entered into two DeltaBase access agreements with Schering-Plough Research Institute (Schering-Plough) and Tanox, Inc. (Tanox.) These agreements provide for
payments aggregating approximately $3.2 million and $545,000, respectively. Under the agreements, Schering-Plough and Tanox have non-exclusive access to a subset of DeltaBase that contains in vivo mammalian gene function information on
certain genes.



In September 2001, Lexicon
Genetics became a subscriber to DeltaBase as part of our litigation settlement with Lexicon. Lexicons subscription to DeltaBase includes non-exclusive, perpetual licenses to the 250 drug targets represented in DeltaBase as of September
2001 and the approximately 1,000 drug targets that were and

##### Table of Contents

are expected to be added to DeltaBase over the subsequent four years. Lexicon pays no subscription fees but will make certain milestone and
royalty payments to us for therapeutic and diagnostic products developed from Lexicons use of DeltaBase.



In May 2001, we entered into a DeltaBase access agreement with Vertex. Under the agreement, Vertex received non-exclusive access to a
subset of DeltaBase that contains in vivo mammalian gene function information on kinases, proteases and certain other gene families. In February 2003, we received notice that Vertex was terminating the agreement.



The DeltaBase agreements grant certain non-exclusive,
worldwide licenses to knockout mice, materials and intellectual property rights under DeltaBase. In addition to the foregoing subscription licensing fees, we may receive additional payments based upon the achievement of designated milestones. We
cannot assure you that we will receive any milestone payments since payments are dependent upon the research, development and commercialization activities of our customers; and Deltagens intellectual property position.



DeltaOne



We recently launched a product line known as DeltaOne that
offers access to our extensive DeltaBase portfolio of knockout mice and/or accompanying phenotypic data, as well as any corresponding intellectual property, on a gene-by-gene basis. Our current customers include Aventis Pharmaceuticals, Euroscreen
S.A. and Millennium Pharmaceuticals. Through December 31, 2002, we have recognized revenue of $400,000 related to our DeltaOne program.



Secreted Protein Program



Overview



Secreted proteins represent proteins that are synthesized for export from the cell or to the surface membrane of the cell where they play
a role in the communication between cells. These communication roles are essential for the formation, regulation, growth and maintenance of multi-cellular organisms. Examples of well-known secreted proteins discovered by other companies include
insulin, human growth hormone and erythropoeitin, or EPO.



Secreted Protein Agreements and Collaborations



In August 2001, we entered into a secreted protein agreement with Eli Lilly (Lilly) to evaluate, and potentially develop and commercialize, therapeutic secreted proteins. Under the terms of the agreement, Lilly
has provided potential targets from its secreted protein pipeline for which we will further evaluate the therapeutic potential in mammalian models. Among those secreted proteins with potential therapeutic value, each company may select proteins for
commercial development, with each company receiving royalties based on sales of therapeutic products. The agreement provides Lilly with certain acquisition, co-promotion, co-marketing and profit-sharing options with respect to therapeutic products
developed and commercialized by us. The agreement also provides us with certain co-promotion, co-development and profit-sharing opportunities.



In October 2001, we entered into a collaboration agreement with Nuvelo, formerly Hyseq, to research, develop and commercialize
biopharmaceutical products based on secreted proteins. Under the terms of the agreement, Nuvelo has provided us with gene sequences encoding secreted proteins and we will utilize our proprietary in vivo mammalian gene knockout technology to
discover and validate potential commercially relevant biopharmaceutical drug targets. We and Nuvelo will each have certain joint development and commercialization rights around potential biopharmaceutical drug targets discovered through the
collaboration. We and Nuvelo will share the collaborations costs; Nuvelo will provide us with approximately $8 million in research and development payments over two years. In addition, we received $10 million in equity proceeds from the sale
of shares of our common stock to George B. Rathmann, Ph.D., chairman of the Board of Directors of Nuvelo.

DeltaSelect



Overview



DeltaSelect is
our custom gene knockout program that uses the platform technology employed in our DeltaBase database program. Our DeltaSelect program is different, however, because our customers select and identify to us the particular genes that they wish to have
knocked out in mice. We provide customers with access to our gene knockout technologies and the resulting knockout mice, data and information generated under each DeltaSelect program. The revenues generated from the DeltaSelect program have been
$585,000, $1.3 million and $926,000 in 2002, 2001 and 2000, respectively, and since 2000 have become a lower percentage of total revenues per year. We anticipate that revenues from DeltaSelect will continue to become less significant to total
revenues and that DeltaSelect will be utilized only under very limited circumstances to develop new technologies, product offerings and programs in collaboration with pharmaceutical companies.



We have produced customized knockout mice at the direction of
our customers for a limited number of pharmaceutical companies. Currently, we have outstanding DeltaSelect knockout programs under agreements with Eli Lilly, GlaxoSmithKline, Merck and Schering-Plough Research Institute.



DeltaSelect Technology



In addition to the proprietary platform technology developed
by us, we are currently employing and developing additional technologies that can be used to create conditional knockout mice. Conditional knockout mice are mice where the gene of interest is removed under unique conditions in a specific tissue or
cell type at selected and controlled times. We are currently developing conditional knockout systems for our DeltaSelect program using Cre/lox and FLP/FRT recombinase technologies.



Research Collaborations



We also enter into various research collaborations with select leading academic and other research institutions. In these research
collaborations, we offer access to knockout mice to the institutions so that they can perform additional studies and analysis.



On February 19, 2002, we announced that we had signed a target validation and research collaboration agreement with Stanford University.
Under the terms of the three-year collaboration, we and Stanford will mutually develop research projects for jointly selected genes under which we will provide Stanford non-exclusive access to knockout mice models using our proprietary
high-throughput technology and Stanford will evaluate and conduct research on such materials. We will have options to obtain exclusive licenses to commercially develop in any and all fields certain inventions developed by Stanford. We will have
rights to use, commercialize and sublicense results developed by Stanford under the research projects.



Customers



In 2000, we entered into DeltaBase Agreements with GlaxoSmithKline and Pfizer that provide these companies the right to access DeltaBase information on gene function. In 2001, as part of our litigation settlement, we entered
into a DeltaBase Agreement with Lexicon Genetics Incorporated. Also, in 2001, we entered into secreted protein agreements with Lilly and Nuvelo. In early 2002, we entered into a DeltaBase Agreement with Merck.



In 2002, we entered into DeltaOne agreements with Aventis
Pharmaceuticals, Euroscreen S.A. and Millennium Pharmaceuticals that offer access to our DeltaBase portfolio of knockout mice and/or accompanying phenotypic data, as well as any corresponding intellectual property on a gene-by-gene basis.



Under our DeltaSelect program, we have entered
into arrangements with major pharmaceutical companies where we produce customized standard, or unconditional, knockout mice. We have performed services or have

continuing obligations under our DeltaSelect program for Schering-Plough Research Institute, Merck, Tularik, Inc. and GlaxoSmithKline.
However, we plan to pursue future DeltaSelect arrangements only in very limited circumstances; therefore, we expect that there will be few, if any, new DeltaSelect customers.



GlaxoSmithKline, Merck and Pfizer accounted for 23%, 35% and 25%, respectively, of our revenues in 2002.



Research and Development



Including our subsidiaries, as of December 31, 2002, we
employed a total of 290 full-time equivalent employees, of which 210 were dedicated to research and development activities. We have spent substantial funds over the past three years to develop our database and other programs and expect to continue
to do so in the future. Research and development expenses were $71.3 million, $45.0 million, and $26.3 million in 2002, 2001 and 2000, respectively. Since December 31, 2002 we have had reductions-in-force and now employ a total of 150 full-time
equivalent employees, of which approximately 120 were dedicated to research and development activities.



Closure of Arcaris, Inc.



On July 30, 2001, we acquired Arcaris, Inc. (Arcaris). Located in Salt Lake City, Utah, Arcaris had developed technologies
consisting of genetic, proteomic and cell-biological systems for identification and validation of drug targets and the creation of small molecule screens. The total purchase price of approximately $8,043,000 consisted of cash of approximately
$450,000 and 766,894 shares of common stock valued at approximately $6,751,000 and 77,329 vested stock options valued at approximately $418,000 and direct acquisition costs of approximately $312,000. In October 2002, we issued an additional 94,095
shares of common stock valued at $112,000 related to certain earn out provisions. The acquisition was accounted for using the purchase method of accounting. The subsidiary was renamed Deltagen Proteomics, Inc.



On January 6, 2002 we announced a cost savings and business
restructuring plan to reduce our cash expenditures. As part of this restructuring plan, we closed the Salt Lake City facility that housed the Deltagen Proteomics, Inc. operations. As a result of the restructuring plan, substantially all Deltagen
Proteomics, Inc. activities and capabilities have ceased or been eliminated.



Acquisition and Closure of BMSPRL, L.L.C. (formerly CombiChem, Inc.)



On February 16, 2002, we acquired the California-based BMSPRL, formerly known as CombiChem, Inc., from Bristol-Myers Squibb Company for
2,647,481 unregistered shares of our common stock valued at approximately $23,510,000 and paid certain transaction expenses of approximately $465,000. The subsidiary was renamed Deltagen Research Laboratories (DRL).



On October 2, 2002 we announced a cost savings and business
restructuring plan to reduce our cash burn rate. As part of this restructuring plan, we closed the San Diego facility that housed the DRL operations. As a result of the restructuring plan, substantially all DRL activities and chemistry capabilities
have ceased or been eliminated.



Acquisition
of XenoPharm, Inc.



On March 14, 2002, we
acquired XenoPharm, a San Diego, California-based private company for 498,236 shares of our unregistered common stock valued at approximately $3.6 million and paid certain transaction expenses. Up to an additional 1,449,262 shares of common stock
may be issued upon the achievement of certain key milestones. The entity became our wholly-owned subsidiary. XenoPharm, which was incorporated in November 2000, provides a proprietary technology platform to pharmaceutical, biotechnology, chemical
and agricultural companies to better understand and predict reactions of foreign substances, named xenobiotics in

human systems. XenoPharms XenoSensor Mice, implanted with human SXR and CAR, coupled with XenoPharms CleanScreen high-thoughput
screening assays provide a proprietary technology platform to improve the predictive value of cell- and animal-based biomedical research.



Intellectual Property



Our policy is to pursue patent protection in the United States around our commercially relevant products, techniques and methods. We
cannot assure you, however, that we will have the financial and staffing resources to pursue patent production on all of our commercially relevant products and methods, or that any of our applications on file with the USPTO will result in the
issuance of any patents, that our patent applications will have priority over others applications, or that, if issued, any of our patents will offer protection against our competitors. Additionally, we cannot assure you that any patent issued
to us will not be challenged, invalidated or circumvented in the future or that the rights created thereunder will provide a competitive advantage. Litigation may be necessary to enforce any patents issued to us, to protect trade secrets or know-how
owned by us or to determine the enforceability, scope and validity of the proprietary rights of others.



Others may have filed and in the future are likely to file patent applications that are similar or identical to ours. To determine the
priority of inventions, we may have to participate in interference proceedings declared by the USPTO that could result in substantial cost to us. We cannot assure you that any patent application of another will not have priority over patent
applications filed by us. Our commercial success depends in part on our neither infringing patents or proprietary rights of third parties nor breaching any licenses that may relate to our technologies and products.



In addition, in certain patent offices around the world, third
parties may institute opposition proceedings against our patent applications, in an effort to prevent their issuance as patents, or against issued patents that we may obtain. Such opposition proceedings may involve substantial costs and time to
defend. In these instances, we cannot assure you that such third parties will not succeed in opposing the issuance of our patents or prevent the continued validity of our issued patents.



We have obtained licenses for certain technologies. However, we cannot assure you that we will be able to
obtain licenses for technology patented by others on commercially reasonable terms, if at all, that we will be able to develop alternative approaches if unable to obtain licenses, or that our current and future licenses will be adequate for the
operation of our business. Our failure to obtain necessary licenses or to identify and implement alternative approaches could have a material adverse effect on our business, financial condition and results of operations.



We also rely upon trade secrets, technical know-how and
continuing invention to develop and maintain our competitive position. We cannot assure you that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or
disclose such technology, or that we can meaningfully protect our trade secrets, or that we will be capable of protecting our rights to our trade secrets.



On May 24, 2000, Lexicon Genetics Incorporated filed a lawsuit against us in the United States District Court for the District of
Delaware. The complaint in the lawsuit alleged that our methods of making knockout mice infringed United States Patent No. 5,789,215, the 215 patent, under which Lexicon claimed to be an exclusive licensee. In addition, on October 13, 2000,
Lexicon and the University of Utah Research Foundation filed a lawsuit against us in the United States District Court for the Northern District of California. The complaint in this lawsuit alleged that we infringed United States Patents Nos.
5,631,153, 5,464,764, 5,627,059 and 5,487,992, or the Capecchi patents, under which Lexicon claimed to be an exclusive licensee. On September 20, 2001, we and Lexicon announced the settlement of the litigation. Under the terms of the
settlement, we obtained a commercial license under the 215 patent and the Capecchi patents, Lexicon obtained a subscription to our DeltaBase product, and all of the claims and counterclaims in the litigation were dismissed

##### Table of Contents

with prejudice. Lexicons subscription to DeltaBase includes non-exclusive, perpetual licenses to the 250 drug targets represented in
DeltaBase as of September 2001 and the approximately 1,000 drug targets that were and are expected to be added to DeltaBase over the subsequent four years. Lexicon will make certain milestone and royalty payments to us for therapeutic and diagnostic
products developed from Lexicons use of DeltaBase. We will make payments to Lexicon for knockout mice generated by us on a fee-for-service basis. Neither we nor Lexicon will pay the other party any subscription or license fees.



On April 28, 2003, we received from Lexicon a letter which
Lexicon claims serves as notice of termination of the sublicense agreement under which we obtained a commercial license to the 215 patent and the Capecchi patents. In this letter, Lexicon specified two grounds that allegedly entitles Lexicon
to terminate the sublicense agreement: (1) our purported material breach of the DeltaBase agreement, under which Lexicon obtained a commercial license to our DeltaBase product; and (2) our purported insolvency. On April 29, 2003, we received from
Lexicon a letter which Lexicon claims serves as notice under the DeltaBase agreement of: (1) Lexicons alleged entitlement to damages in the amount of $25 million, plus attorneys fees and costs, for our purported material breach of the
DeltaBase agreement; and (2) alleged noncompliance with the content criteria in the DeltaBase agreement. We note that these letters from Lexicon follow shortly after our press release on April 4, 2003, in which we announced our receipt of a bridge
loan and our efforts to obtain an equity financing. We believe that Lexicons claims and allegations are without merit, and intend to promptly address these claims according to the dispute resolution procedures provided by the settlement and
other agreements between Lexicon and Deltagen.



Competition



We face significant competition in the area
of genomics-based research from for-profit companies such as Celera Genomics, Curagen, Inc., Exelixis, Inc., GeneLogic, Inc., Human Genome Sciences, Inc., Incyte Pharmaceuticals, Inc., Lexicon Genetics Incorporated and Millennium Pharmaceuticals,
Inc., among others, many of which have substantially greater financial, scientific and human resources than we do. In addition, the Human Genome Project and a large number of universities and other not-for-profit institutions, many of which are
funded by the U.S. and foreign governments, are also conducting research to discover genes and their function.



We face, and will continue to face, significant competition in our efforts to validate drug targets and to secure funding for research.
Many other companies have or are developing capabilities in the use of living organisms, including the analysis of human genetic profiles, to define gene function. These competitors include such companies as Lexicon Genetics Incorporated, Exelixis,
Inc., Nuvelo, Inc., deCODE Genetics Inc. and Devgen N.V. Additionally, many genomics companies may expand their capabilities to determine gene function. We also believe that some pharmaceutical and biotechnology companies are discussing the
possibility of working together to discover the functions of genes and share gene function-related data among themselves. The formation of this type of consortium could reduce the customer base for our gene function-related business. Further, as we
expand our range of programs, products and services, such as our secreted protein program, we will compete with additional companies, many of which have substantially greater financial, scientific and human resources than we do and some of which may
be our customers at that time or potential customers including, Merck, GlaxoSmithKline and Pfizer. We may also be competing directly with biotechnology drug companies, such as Genentech Inc., Amgen Inc. and Abgenix Inc., that have significantly
greater experience and expertise in discovering and developing biopharmaceuticals, such as secreted proteins.



Companies focused specifically on other organisms, such as fruit flies, worms and yeast, use methods of identifying potential drug targets
that are different than ours. In addition, pharmaceutical, biotechnology and other genomics companies, as well as a number of universities and other not-for-profit institutions, are seeking to develop competing technologies. Many of these
competitors have substantially greater financial, scientific and human resources than we do. Many of these competitors also have substantially greater experience than we do in their respective fields. As a result, our competitors may succeed in
developing products and technologies earlier than we do or in developing products and technologies that are more effective than ours.



15

##### Table of Contents



We believe
that the principal competitive factors in selling our products and services are the quality and reliability of the gene function information, the volume of the gene function information, the features and ease of use of database products and the cost
and pricing of competing products. We believe that we compete favorably with respect to these factors; however, our market is rapidly changing and we expect to face further competition from new market entrants and consolidation of our existing
competitors.



Government Regulation



Regulation of Animal Use



The federal Animal Welfare Act, or AWA, governs the humane
handling, care, treatment and transportation of some animals used in research activities in the United States. Rats, birds and mice, including the mice in our knockout programs, are currently excluded from the definition of animal and,
therefore, are not subject to regulation under the AWA. However, the United States Department of Agriculture, which enforces the AWA, has been sued on this matter and agreed, as part of the settlement of this lawsuit on September 25, 2000, to begin
the process of changing the regulations issued under the AWA to include rats, mice and birds within its coverage. Congress subsequently prohibited, in the Agricultural Appropriations Act for fiscal year 2001 and again for fiscal year 2002, the
expenditure of any money or the commencement rulemaking for the purpose of changing the regulations with respect to including rats, mice and birds prior to October 1, 2002. We cannot predict whether mice will at any time after such date be included
under the AWA. The AWA imposes a wide variety of specific regulations on producers and users of animal subjects, most notably personnel, facilities and statistical standards, cage size, feeding, watering and shipping conditions and environmental
enrichment methods. If the USDA decides to include mice in its regulations, we could be required to alter our production operation for these models, including adding production capacity, new equipment and additional employees. It is possible that
the USDAs actions will negatively affect our operations. In addition, although we do not anticipate the addition of mice to the AWA, if such addition were to happen, to require significant expenditures, it is possible that the AWA, when
amended, may be more stringent than we expect and require significant expenditures. Any future amendments to the AWA or other laws or regulations may also require significant expenditures by us.



Furthermore, some states have their own regulations, including
general anti-cruelty legislation, which establish certain standards in handling animals. To the extent that we provide products and services overseas, we also have to comply with foreign laws, such as the European Convention for the Protection of
Animals During International Transport and other anti-cruelty laws. The Council of Europe is presently considering proposals to more stringently regulate animal research.



Regulation of Genetically Modified Organisms



Since we are in the business of developing animals containing
changes in their genetic make-up, we may become subject to a variety of laws, guidelines, regulations and treaties specifically directed at genetically modified organisms, or GMOs. The area of environmental releases of GMOs is rapidly evolving and
is currently subject to intense regulatory scrutiny, particularly internationally. Current laws, guidelines and other requirements typically include confinement requirements for preventing the spread of GMOs into the environment. Examples of these
guidelines in the U.S. include the National Institutes of Health Guidelines for Research Involving Recombinant DNA Molecules and the USDAs Guidelines for Research Involving the Planned Introduction into the Environment
of Genetically Modified Organisms. Although these guidelines typically apply only to federally-funded activities, if we were to become subject to similar laws in the future, we could incur compliance costs.



The Biosafety Protocol, or the BSP, is also of particular
importance to our international operations. The BSP, a treaty adopted in Montreal, Canada in late 1999, is expected to be ratified in many countries, although the timeframe is uncertain. Many industrialized and non-industrialized countries will be
signatories to the BSP. Although the U.S. is not subject to the BSP, if ratified, the BSP is expected to cover shipments from the U.S. to



16

##### Table of Contents

countries abroad that have signed the BSP. The BSP is also expected to cover the importation of living modified organisms, a category that
could include our animals. If our animals are not contained as described in the BSP, our animals could be subject to the potentially extensive import requirements of countries that are signatories to the BSP.



Other Regulations



We are also subject to a variety of other federal and state
laws and regulations in the U.S. and in other countries pertaining to our facilities, the shipment, exportation and importation of various articles and health and safety matters. For example, the Department of Transportation and various
international guidelines and regulations govern the transport of different types of materials. The Bureau of Export Administration of the Department of Commerce exercises export controls over technology such as our gene database. The Department of
Health and Human Services and USDA both regulate various types of articles that present the possibility of spreading communicable and other diseases, including the regulation of vectors, such as animals and articles that present risks of other harm
to plants, human beings and other animals. The Environmental Protection Agency has responsibility for facility emissions and other environmental matters, including the regulation of new chemical substances, which could include gene sequences.



Employees



As of December 31, 2002, we employed 268 employees. After
taking into account part-time employees and contractors, we employed 290 full-time equivalent employees as of that date. Of these, 41 hold Ph.D.s and 15 hold other advanced degrees. None of our employees are represented by a labor union. We
consider our relations with our employees to be good. Reductions-in-force subsequent to December 31, 2002 have reduced the number of employees to approximately 150.

RISKS



We may be unable to complete the private placement.



As more fully described in Part I of this
report under the heading Overview, on April 2, 2003, we entered into a definitive purchase agreement with certain investors to raise a minimum of $10 million through the issuance of Series A Preferred Stock. Consummation of the
transactions contemplated by the purchase agreement is subject to our obtaining stockholder approval and other closing conditions. If we are not able to complete the private placement on time, it is likely that we will cease our operations. Our
inability to obtain additional funding through the private placement would likely cause us to explore liquidation alternatives, including the initiation of bankruptcy proceedings. If this were to occur, after repayment of our obligations including
the bridge loan received from the private placement investors, any investment in us would likely decline to zero.



We expect to continue to incur substantial losses and we may never achieve profitability, which in turn may harm our future operating performance and
may cause the market price of our stock to decline.



We have had net losses every year since our inception in 1997 and, as of December 31, 2002, had an accumulated deficit of $206.3 million. We had net losses of $107.2 million, $48.5 million and $32.2 million in 2002, 2001 and 2000,
respectively. The 2000 net loss is before a $22.4 million deemed dividend-related to the beneficial conversion of our preferred stock. Because we anticipate significant expenditures for our research and development programs and for the development,
implementation and support of our gene function database, we may report substantial net losses through at least the next several years. We may never achieve profitability. If we do not become profitable within the time frame expected by securities
analysts or investors, the market price of our stock will likely decline. If we do achieve profitability, we may not sustain or increase profitability in the future.



Our expenditures increased in 2002 due in part to:



| |  |  | our acquisitions of Arcaris, Inc. and BMSPRL, L.L.C.;
| | - |  | -----------------------------------------------------



| |  |  | an impairment of our goodwill and certain long-lived assets;
| | - |  | ------------------------------------------------------------



| |  |  | restructuring charges associated with workforce reductions and facility closures; and
| | - |  | -------------------------------------------------------------------------------------



| |  |  | continued investment in the research and development of our new and existing products and our technology, including increased investment for the development,
implementation and support of our gene function database, our standard and conditional knockout programs, our secreted protein programs and identification of lead candidate compounds for drug development.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We will need to raise additional capital that may not be available, which
if not available, will adversely affect our operations.



With our acquisitions in 2001 and 2002 and the corresponding expansion of the scope of our activities, our expenditures and our underlying burn rate increased significantly in 2002. In that same time, our products and services have
not produced revenues sufficient to fund our expanded activities for an adequate period of time into the future to continue to execute our business plan. In addition, our products and services may not in the future produce revenues that, together
with our existing cash and other resources, are adequate to meet our anticipated cash needs. We plan to continue to fund our operations from our existing cash balances and cash flows, but expect to seek to raise additional funds from the sale of
stock, either through private financing and/or a public offering, or from debt financing. Our cash requirements depend on numerous factors, including:



| |  |  | our ability to attract and retain customers for our gene function database and other products and services;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | expenses in connection with the development and expansion of our gene function database, our secreted protein or other products and services;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents



| |  |  | expenditures in connection with license agreements and acquisitions of and investments in complementary technologies and businesses; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the need to increase research and development spending to keep up with competing technologies and market developments.
| | - |  | ----------------------------------------------------------------------------------------------------------------------



Substantial capital has been used to fund our operating
losses. Since inception, we have experienced negative cash flows from operations and expect to experience negative cash flows from operations for the near future.



We have required substantial amounts of capital, and though operating costs have been significantly reduced
over the past six months, we will continue to require additional capital in the future, to fund our business operations. The rate at which our capital is utilized is affected by the operational and developmental costs incurred and the extent to
which our products gain acceptance.



We continue
to evaluate alternative means of financing to meet our needs on terms that are attractive to us. Although we have recently implemented a business realignment and staff reductions to reduce our cash burn rate, if we are not able to obtain needed
capital, we will have to take additional actions to conserve our cash balances, including further reductions in our operating expenses, downsizing of our staff and reduction in facilities, all of which may have a material adverse effect on our
business, financial condition and our ability to reduce losses or generate profits.



When we need additional funding, we may be unable to obtain it on favorable terms, or at all. For example, we may be forced to enter into financing arrangements at significant discounts. If adequate
funds are not available, we may have to curtail operations significantly or obtain funds by entering into arrangements requiring us to relinquish rights to certain technologies, products or markets. In addition, if we raise funds by selling stock or
convertible securities, our existing stockholders could suffer dilution.



If we complete the private placement and the related rights offering, our current stockholders will experience substantial dilution.



Consummation of the private placement will have a highly dilutive effect on our current stockholders. The number of shares issued pursuant
to the private placement will increase substantially the number of shares of our capital stock currently outstanding and thereby the percentage ownership of our current stockholders will significantly decline as a result of the private placement.
Further, the conversion of the preferred stock issued in the private placement would increase substantially the number of shares of our common stock currently outstanding. The percentage represented by the shares issued in the private placement
could be higher or lower depending on the per share purchase price to be determined just prior to the closing. By way of example, based on the currently committed amount of $10 million plus certain shares to be issued to Charles Rivers Laboratories,
a per share purchase price of $0.20 would mean a percentage ownership of 57%, whereas a per share purchase price of $0.40 would mean a percentage ownership of 40%. In addition, the committed amount could increase, which would increase the percentage
ownership associated with the newly issued shares. If the per share purchase price was $0.20, a committed amount of $15 million would mean a percentage ownership of 66%, and a committed amount of $25 million would mean a percentage ownership of 76%.
For purposes of example only, based on a committed amount of $10 million and a per share purchase price of $0.20, a stockholder who owned approximately 10% of our outstanding stock prior to the private placement, would own approximately 4.3% of our
outstanding stock immediately after consummation of the private placement.



Following consummation of the private placement, we will conduct a registered rights offering to our other shareholders that would enable them to purchase a number of shares of preferred stock
sufficient to maintain their percentage ownership in Deltagen at the same per share price as is paid by the investors in the private placement. The more shares purchased in the rights offering, the lower the percentage ownership of the private
placement investors, although we expect they will continue to have a significant ownership percentage going

forward. This rights offering will represent further dilution to those stockholders who do not choose to participate by buying shares of
preferred stock in that offering.



We have recently
implemented business restructurings and several staff reductions, and may need to do so again in order to further reduce burn rate and operating expenses.



In October 2002, we instituted a cost savings and business restructuring plan to reduce our cash burn rate in response to market
conditions. As part of the restructuring, we reduced our staff by approximately 130 employees, a reduction of about 30%. The plan also included the closing of facilities, including our DRL site in San Diego, California, and the consolidation of
certain core activities into our Redwood City, California and Salt Lake City, Utah facilities. In January 2003, we decided to close additional operations and facilities including Salt Lake City, Utah and Deltagen Europe and reduce our staff to
approximately 200 employees. A further workforce reduction to 150 employees was announced in April 2003. The benefit of implementing this plan is expected to be realized over the first half of 2003. As a result of these actions, we recorded charges
in 2002 for the impairment of goodwill and intangible assets related to activities that will no longer be pursued or that will be scaled back, for the impairment of fixed assets including leasehold improvements and equipment and restructuring
charges for severance and other employee related costs, costs associated with lease obligations and other costs. We expect to record further charges for impairment of fixed assets, restructuring charges for severance and other employee related
costs, costs associated with lease obligations and other costs in the first and second quarters of 2003.



Due to the uncertainties in predicting our future revenues and our ability to obtain additional financing, we may need to consider and
implement another business restructuring, which may also comprise staff reductions in order to further reduce our cash burn rate and to maintain viability.



We have recently experienced a significant reduction in our workforce, which may have a material impact on our operations and our ability to meet our
existing contractual obligations



In October
2002, we announced that we were reducing our staff by approximately 130 employees, a reduction of about 30%. In January 2003, we decided to close additional facilities and reduce our staff to approximately 200 employees. Further staff
reductions were announced in April 2003 in order to reduce our work force to approximately 150 employees. Because of the magnitude of the workforce reductions, it is uncertain whether these layoffs will have a material adverse impact on our ability
to meet our existing contractual obligations and whether we will be able to expand our operations in the future to meet customers or partners needs.



We have experienced problems managing our growth, and if we fail to properly manage our growth in the future, our business
could be adversely materially affected.



From 2000 through September 30, 2002, we had experienced significant growth in the number of our employees to approximately 450 employees and the scope of our operations, including acquisitions of Arcaris (renamed Deltagen
Proteomics) and BMSPRL (renamed Deltagen Research Laboratories), and an increase in the scale of our mouse knockout program, as well as our secreted protein and biopharmaceutical drug discovery and development programs. As of December 31, 2002, we
had approximately 290 full-time equivalent employees.



As of December 31, 2002, we also had multiple offices and facilities in North America and Europe, which presented significant challenges and strain on our management and operations. In addition to our corporate headquarters in
Redwood City, California, we had offices or facilities in Menlo Park, Alameda and San Carlos, California, as well as facilities in Strasbourg, France for Deltagen Europe, S.A., in Salt Lake City, Utah for Deltagen Proteomics and in San Diego,
California for Deltagen Research Laboratories.

In response to
market conditions, our cash position, and the cost and challenges associated with multiple facilities and a rapidly growing workforce and operational scope, we announced in October 2002, that we were implementing a cost savings and business
restructuring plan to reduce our cash burn rate. As part of the realignment, we reduced our staff by approximately 130 employees, a reduction of about 30%. The plan also included the closing of facilities, including our DRL site in San Diego,
California, and the consolidation of certain core activities into our Redwood City, California and Salt Lake City, Utah facilities. In January 2003, we decided to close additional facilities, including our Deltagen Europe, S.A. site in Strasbourg,
France and Deltagen Proteomics site in Salt Lake City, Utah. We reduced our staff to approximately 200 employees. Subsequently we further consolidated our facilities to one site in Redwood City, California and one site in San Carlos, California. In
April 2003 we announced further staff reductions that are expected to bring our head count to 150 employees.



We may need in the future to again increase our workforce, acquire additional businesses or technologies, expand the size and number of
our offices and facilities, and broaden the scope of our operations. It is uncertain whether we will be able to accomplish those objectives and, further, we may not be able to manage our future growth successfully. If we are unable to manage our
future growth successfully, our business could be adversely materially affected.



We are a relatively new public company with an unproven and evolving business strategy, and our limited history of operations makes evaluation of our business and prospects difficult.



We have had a limited operating history and are at an early
stage of development. Our pricing models for offering our products and services are unproven. We currently have four full subscribers for our DeltaBase gene function database, only three of which are paying subscription fees. We have generated only
limited revenues amounting to approximately $17.7 million, $9.9 million and $2.1 million for the fiscal years 2002, 2001 and 2000, respectively. Our success will depend on, among other things, our ability to enter into future licensing and other
agreements on favorable terms, our ability to determine and generate information on those genes that have potential use as drug targets and the commercialization of products using our data. Our sales force may not succeed in marketing our DeltaBase
and DeltaOne products, and our employees may not succeed in implementing and operating our database products in a manner that is satisfactory to our subscribers. Furthermore, the plans for our secreted protein and conditional knockout programs are
unproven, and we cannot be sure that we will ever be able to develop these programs or that any program that we develop will be commercially successful. As a result of these factors, it is difficult to evaluate our prospects, and our future success
is more uncertain than if we had a longer or more proven history of operations.



We currently have only four DeltaBase subscribers, two customers for a subset of DeltaBase and three DeltaOne customers and will not succeed unless we can attract more customers.



DeltaBase has been our principal source of revenue. We also
expect a significant portion of our revenues for at least the next six months will be derived from fees under our DeltaBase agreements.



We currently have only four DeltaBase customers (including Lexicon, which does not involve the receipt of any subscription fees) and two
customers for a subset of DeltaBase. Because of our reliance on revenue generated under our DeltaBase agreements, we will likely not succeed unless we can attract more DeltaBase customers. In addition, we cannot be sure of the terms under which we
may enter into future agreements, such as fees payable to us or the term of the agreements, if any, or whether existing customers will continue as customers once their DeltaBase agreements end. Also, if our database is not acceptable to our
prospective customers, it may not generate revenues and our business and financial condition will be materially harmed.



We may not be able to comply with minimum performance levels or restrictive provisions or other obligations that may be contained in any
agreements, such as minimum data delivery requirements. In addition, we may experience unforeseen technical complications in the processes we use to generate functional data for our gene database and functional genomics resources. These
complications could materially delay or



22



---

##### Table of Contents

limit the use of our gene function database, substantially increase the anticipated cost of generating data or prevent us from implementing
our processes at appropriate quality and scale levels, thereby causing our business to suffer.



We currently have only four customers for our DeltaSelect program and only three DeltaOne customers. Revenues from our DeltaSelect program have historically not been significant, and we expect to enter
into only a limited number, if any, of future DeltaSelect agreements. To succeed we must attract customers for our DeltaBase and other programs. DeltaOne is a new program and it is uncertain whether we can attract customers or whether it will affect
our ability to attract further DeltaBase customers. Our existing and future agreements may not be renewed and may be terminated without penalty in the event either party fails to fulfill its obligations under one of these agreements. Failure to
renew or the cancellation of these agreements by one of our customers could result in a significant loss of revenues.



Over the past several years, companies in the pharmaceutical industry have undergone significant consolidation. As such companies merge,
we will have fewer potential customers for our products. Also, if two or more of our present or future customers merge, we may not be able to receive the same fees under agreements with the combined entities that we were able to receive under
agreements with these customers prior to their merger. Moreover, if one of our customers merges with an entity that is not a customer, the new combined entity may prematurely terminate our agreement. Any of these developments could materially harm
our business or financial condition.



There have been very few
drugs developed and commercialized using genomics-based research and, therefore, the future of our products and programs is uncertain.



Very few of the limited number of drugs developed to date using genomics-based research have reached the commercial market. We cannot
assure you that genomics-based drug development efforts will ultimately be commercially successful. We have not proven our ability either to identify drug targets with definite commercial potential or commercialize drug targets that we do identify.
We cannot assure you that a particular gene function in a mouse will have any correlation to a human patients response to a particular drug. It is difficult to successfully select those genes with the most potential for commercial development.
Furthermore, we do not know that any products based on genes that are the subject of our research can be successfully developed or commercialized. If commercial opportunities are not realized from genomics-based research, our existing customers
could stop using our products or we could have difficulty attracting or retaining customers and, in any event, we would not realize any product royalties.



There may be ethical and other concerns surrounding the use of genetic information that could limit our ability to develop and sell our existing
products and new products.



The genetic
screening of humans has raised ethical issues regarding the confidentiality and appropriate uses of the resulting information. Government authorities may regulate or prohibit the use of genetic testing to determine genetic predispositions to certain
conditions. The FDA currently is considering different mechanisms for regulating certain types of genetic tests. To the extent any of our technology or products based on our technology involve human genetic testing, such products could be subject to
additional FDA regulation in the future. Additionally, the public may disfavor and reject the use of genetic testing. It is possible that the government authorities and the public may fail to distinguish between the genetic screening of humans and
genomic and proteomic research. If this occurs, our products and the processes for which our products are used may be subject to government regulations intended to affect genetic screening. Further, if the public fails to distinguish between the two
fields, it may pressure our customers to discontinue the research and development initiatives for which our products are used. If this occurs, the potential market for our products could be reduced, which could seriously harm our financial condition
and results of operations.

##### Table of Contents



Our DeltaBase customers
will control the development and commercialization of products, which may mean that our research efforts will never result in any royalty payments or third party product sales.



Our DeltaBase agreements with our customers may provide us with rights to obtain milestone payments and/or
royalties from the commercial development of therapeutic or diagnostic compounds derived from access to our mice, database, technology or intellectual property. However, we may not be able to obtain these rights under future agreements. Our ability
to obtain these rights depends in part on the advantages and novelty of our technologies, the validity of our intellectual property, the usefulness of our data and our negotiating position relative to each potential customer.



We will have limited or no control over the resources that any
customer may devote to product development based on its access to our database. These customers may breach or terminate their agreements with us, and they are not obligated to conduct any product discovery, development or commercialization
activities at all. Further, our customers may decide not to develop products arising out of our agreements or may not devote sufficient resources to the development, approval, manufacture, marketing or sale of these products. If any of these events
occurs, our customers may not develop or commercialize any products based on our gene function research, technologies or intellectual property, we would not receive milestone payments or royalties on product sales and the results of our operations
would suffer. Furthermore, our customers may resist sharing revenue derived from the successful commercialization of a drug through royalty payments or others may have competing claims to all or a portion of such revenues.



Our ability to discover, develop or commercialize products could be
adversely affected if our research and marketing collaborations are terminated.



Under certain of our agreements, particularly our secreted protein collaboration agreements, we share with our collaborators certain co-development, co-promotional and co-marketing rights to
pharmaceutical products based on our discoveries. Many of these collaborators have much greater financial, scientific and human resources capabilities and more experience than us in developing, marketing, promoting and selling pharmaceutical
products. As a result, our ability to discover, develop and commercialize products will depend on the continuation of these collaborations. If any of these collaborations are terminated, we may not be able to enter into acceptable collaborations
with other collaborators that have similar resources or experience. In addition, our existing collaborations may not be successful. Disputes may arise between us and our collaborators as to a variety of matters, including financing obligations under
our agreements and ownership of intellectual property rights. These disputes may be both costly and time-consuming and may result in delays in the development and commercialization of products.



There are a finite number of gene families upon which pharmaceutical and
biotechnology companies focus their research, which limits our potential revenue and growth.



Our current and potential subscribers and customers traditionally focus their research and development efforts on a finite number of gene
families that they view as reliable drug targets. Once we provide functional information on these gene families, our ability to attract and retain subscribers to our database will depend, in part, on the willingness of our subscribers to expand
their research and development activities to other gene families. If our customers do not do this, we may lose existing subscribers or fail to attract new subscribers for our database services and, as a result, our business and financial condition
may be significantly harmed. In addition, we have made and will continue to make significant investments in our database and knockout programs that we may not recoup if we cannot find additional target opportunities.

We may fail to meet market
expectations, which could cause our stock price to decline.



The following are among the factors that could cause our operating results to vary significantly from market expectations:



| |  |  | changes in the demand for and pricing of our products and services;
| | - |  | -------------------------------------------------------------------



| |  |  | the nature, pricing and timing of other products and services provided by us or our competitors;

Our revenues will be unpredictable and this may harm our financial condition.



The amount and timing of revenues that we may have from our business will be unpredictable because:

| |  |  | our sales cycle is lengthy, as described below.
| | - |  | -----------------------------------------------



As a result, our results may be below market expectations. If this happens, the price of our common stock may decline.



We expect that our sales cycle will be lengthy, which will cause our
revenues to be unpredictable and our business to be difficult to manage.



Our ability to identify and obtain subscribers for our gene function database product and other services depends upon whether customers believe that our products and services can help accelerate drug
discovery efforts. Our sales cycle will be lengthy because of the need to educate potential customers and sell the benefits of our products and services to a variety of constituencies within potential subscriber companies. These companies are
typically large organizations with many different layers and types of decision-makers. In addition, each database subscription and development program or services agreement will involve the negotiation of unique

terms and issues which will take a significant amount of time. We may expend substantial funds and management effort with no assurance that a
subscription program or services agreement will result. Actual or proposed mergers or acquisitions of our prospective customers may also affect the timing and progress of our sales efforts. Any of these developments could harm our business or
financial condition.



We may have conflicts or be in
competition with our customers, which will hurt our business prospects.



Disagreements could arise with our customers or their partners over rights to our intellectual property or our rights to share in any of the future revenues of compounds or therapeutic approaches
developed by our customers. These kinds of disagreements could result in costly and time-consuming litigation and could have a negative impact on our relationship with existing customers. Any conflict with our customers could reduce our ability to
attract additional customers or enter into future customer agreements. Some of our customers could also become competitors in the future. Our customers could develop competing products, preclude us from entering into agreements with their
competitors or terminate their agreements with us prematurely.



We experience intense competition from other entities engaged in the study of genes, and this competition could adversely affect our business.



The human and mouse genomes contain a finite number of genes. The human genome has been mapped and
identified. Our competitors have identified and will continue to identify the sequence of numerous genes in order to obtain proprietary positions with respect to those genes. In addition, our competitors may seek to identify and determine the
biological function of numerous genes in order to obtain intellectual property rights with respect to specific uses of these genes, and they may accomplish this before we do. We believe that the first company to determine the functions of
commercially relevant genes or the commercially relevant portions of the genome will have a competitive advantage.



A number of companies, institutions and government-financed entities are engaged in gene sequencing, gene discovery, gene expression
analysis, gene function determination and other gene-related service businesses. Many of these companies, institutions and entities have greater financial and human resources than we do and have been conducting research longer than we have. In
particular, a significant portion of this research is being conducted by private companies and under the international Human Genome Project, a multi-billion dollar program funded, in part, by the U.S. government, which completed and released its
initial rough draft of the human genome in June 2000; a final, high-quality sequence analysis is expected as early as 2003. Furthermore, other entities have and will continue to discover and establish a patent position in genes or gene sequences
that we wish to study. Significant competition also arises from entities using standard target identification approaches, traditional knockout mouse technology and other functional genomics technologies. These competitors may have or may acquire
intellectual property rights in functional or other data that are superior to or dominant over our rights. These competitors may also develop products earlier than we do, obtain regulatory approvals faster than we can and invent products and
techniques that are more effective than ours. Furthermore, other methods for conducting functional genomics research may ultimately prove more advanced, in some or all respects, to the use of knockout mice. In addition, technologies more advanced
than or superior to our gene function identification technology may be developed, thereby rendering our gene trap and gene function identification technologies obsolete. As we expand our range of products and services, such as our secreted protein
and biopharmaceutical development programs, we will compete with additional companies, some of which may be our customers at that time or our potential customers.



Some of our competitors have developed commercially available databases containing gene sequence, gene
expression, gene function, genetic variation or other functional genomic information and are marketing or plan to market their data to pharmaceutical and biotechnology companies. Additional competitors may attempt to establish databases containing
this information in the future. We expect that competition in our industry will continue to intensify. We also believe that some pharmaceutical and biotechnology companies are discussing the possibility of working together to discover the functions
of genes and share gene function-related data among themselves. The formation of this type of consortium could reduce the prospective customer base for or interest

in our gene function-related business. Moreover, the pharmaceutical industry has undergone significant mergers and this trend is expected to
continue. This concentration of the industry could further limit our potential customer base and therefore materially harm our business.



Our acquisition of XenoPharm might not produce the expected benefits.



It may turn out that there are no advantages or synergies to adding XenoPharms research
capabilities to Deltagens product line and technology platform. XenoPharm continues to incur legal expenses in connection with its patent applications and the patent applications of its licensors. It is expected that these expenses will
increase as the level of patent prosecution increases. In the case of certain of these patent applications, it is our understanding that several major pharmaceutical companies have also filed patent applications covering such technologies and these
pharmaceutical companies have sufficient capital resources to withstand potentially costly and lengthy patent interference and opposition proceedings, if they should choose to challenge these applications or any patents issuing there from. We cannot
assure that we will prevail in any such proceedings. If we do not prevail, the value of these technologies will likely be significantly reduced.



We may engage in future acquisitions or licenses, which could adversely affect your investment in us as we may never realize any benefits from such
acquisitions or licenses, which also could be expensive and time consuming.



We may acquire and license additional products and programs, if we determine that these products or programs complement our existing technology or augment our existing information technology platforms.
We currently have no firm commitments or agreements with respect to any material acquisitions. If we do undertake any transactions of this sort, the process of integrating an acquired business, technology, service or product may result in operating
difficulties and expenditures and may absorb significant management attention that would otherwise be available for ongoing development of our business. Moreover, we may never realize the anticipated benefits of any acquisition or license. Future
acquisitions could result in potentially dilutive issuances of equity securities, the incurrence of debt and contingent liabilities and amortization expenses related to goodwill and other intangible assets, which could adversely affect our results
of operations and financial condition.



We depend on key
employees, and without the services of our key employees, we may not achieve profitability or remain viable.



Our future success also will depend in part on the continued service of our key scientific, software, legal, consultant and management
personnel and our ability to identify, hire and retain additional personnel, including customer service, marketing and sales staff. We experience intense competition for qualified personnel. We may be unable to attract and retain personnel necessary
for our business. Moreover, our business is located in the San Francisco Bay Area of California, where demand for personnel with the skills we seek is extremely high and is likely to remain high. Because of this competition, our compensation costs
may increase significantly.



We currently do not have any
issued U.S. patents relating to knockout mice or therapeutics, and if we are unable to protect our proprietary information, our business will be adversely affected.



Our business and competitive position depends upon our ability to protect and exploit our proprietary
techniques, methods, compositions, inventions, database information and software technology. However, our strategy of obtaining such proprietary rights around as many genes as possible is unproven. Protecting our intellectual property rights is
costly and we may not therefore be in a position to obtain protection around all of our inventions and other intellectual property rights. Unauthorized parties may attempt to obtain and use information that we regard as proprietary. Although we
intend for our gene function database subscription agreements to require our potential subscribers to control access to our database and information, policing unauthorized use of our database information and software may be difficult.

Although we
currently have certain issued United States patents, none of these relate to knockout mice or therapeutics. Patents have been issued to other entities based on claims relating to knockout mice or therapeutics. In addition, many applications have
been filed seeking to protect partial human gene sequences, many of which are based primarily on gene sequence information alone. Some of these applications have issued as patents. Some of these may claim sequences that we have used or may use in
the future to generate knockout mice in our gene knockout program or that we have used or may use in the future to discover and develop biopharmaceutical products. In addition, other applications have been filed which seek to protect methods of
using genes and gene expression products, some of which attempt to assign biological function to the DNA sequences based on laboratory experiments, computer predictions, mathematical algorithms and other methods.



The issuance of these applications as patents will depend, in
part, upon whether practical utility can be sufficiently established for the claimed sequences and whether sufficient correlation exists between the experimental results, predictions, algorithms and other methods and actual functional utility. The
patent application process before the U.S. Patent and Trademark Office and other similar agencies in other countries is confidential in nature. Although certain patent applications are published prior to issuance, as each application is evaluated
independently and confidentially, we cannot predict whether applications have been filed or which, if any, will ultimately issue as patents. However, it is probable that patents will be issued to our competitors claiming knockout mice, partial human
gene sequences and methods of using genes and gene expression products.



Numerous applications have been filed by other entities claiming gene sequences. Many patents have already issued and we expect more will issue in the future. In addition, others may discover uses for genes or proteins other
than uses covered in any patents issued to us, and these other uses may be separately patentable. We may not be able to obtain additional issued patents on our patent applications because our patent applications may not meet the requirements of the
patent office. The holder of a patent covering a particular use of a gene or a protein, isolated gene sequence or deduced amino acid sequence could exclude us from using that gene, protein or sequence. In addition, a number of entities make gene
information, techniques and methods publicly available, which may affect our ability to obtain patents.



Some of our patent applications may claim compositions, methods or uses that may also be claimed in patent applications filed by others.
In some or all of these applications, a determination of priority of inventorship may need to be decided in an interference proceeding before the U.S. Patent and Trademark Office. Regardless of the outcome, this process is time-consuming and
expensive.



Issued patents may not provide
commercially meaningful protection against competitors. Other companies or institutions may challenge our or our customers patents or independently develop similar products that could result in a legal action. In the event any researcher or
institution infringes upon our or our customers patent rights, enforcing these rights may be difficult and can be time-consuming. Others may be able to design around these patents or develop unique products or technologies providing effects or
results similar to our products or technologies.



Our ability to use our patent rights to limit competition in the creation and use of knockout mice, as well as our ability to obtain patent rights, may be more limited in certain markets outside of the United States because the
protections available in other jurisdictions may not be as extensive as those available domestically.



We pursue a policy of having our employees, consultants and advisors execute nondisclosure and nonuse confidentiality agreements, as well
as proprietary information and invention agreements when they begin working for us. However, these agreements may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of
unauthorized use or disclosure. We also cannot prevent others from independently developing technology or software that might be covered by copyrights issued to us, and trade secret laws do not prevent independent development.

We may be subject to
litigation and infringement claims that may harm our business or reputation, be costly and divert managements attention.



The technology we use in our business may subject us to claims that we infringe on the patents or proprietary rights of others. The risk
of this occurring will tend to increase as the genomics, biotechnology and software industries expand, more patents are issued and other companies attempt to discover gene function through mouse gene knockouts and engage in other genomics-related
businesses. Furthermore, many of our competitors and other companies performing research on genes have already applied for patents covering some of the genes upon which we perform research, and many patents have already been issued which cover these
genes, as well as genes we may wish to use in the future.



We may be involved in future lawsuits alleging patent infringement or other intellectual property rights violations. In addition, litigation may be necessary to:



| |  |  | assert claims of infringement;
| | - |  | ------------------------------



| |  |  | enforce our patents, if any;
| | - |  | ----------------------------



| |  |  | protect our trade secrets or know-how; and
| | - |  | ------------------------------------------



| |  |  | determine the enforceability, scope and validity of the proprietary rights of others.
| | - |  | -------------------------------------------------------------------------------------



We may be unsuccessful in defending or pursuing these lawsuits. Regardless of the outcome, litigation can be
very costly, can divert managements efforts and could materially affect our business, operating results, financial condition and cash flows. An adverse determination may subject us to significant liabilities or restrict or prohibit us from
selling our products.



Whether or not
meritorious, litigation brought against us could result in substantial costs, divert managements attention and resources, and harm our financial condition and results of operations.



Because our issued U.S. patents are not related to knockout mice or therapeutics, and because knockout mouse and
gene-related patents even if obtained may not be enforceable, our intellectual property may not have any material value, which would diminish our business prospects.



One of our strategies is to obtain proprietary rights around our commercially relevant gene knockouts.
Although we have filed patent applications covering the large majority of knockout mice we have produced, we do not currently have any issued patents related to knockout mice and may not have the financial means to maintain all or most of these
applications. We rely on a combination of copyright and trademark law, trade secrets, non-disclosure agreements and contractual provisions in our agreements with our customers to establish and maintain intellectual property rights. While the U.S.
Patent and Trademark Office in the past has issued patents to others covering function of genes, knockout mice, types of cells, gene sequences and methods of testing cells, we do not know whether or how courts may enforce those patents, if that
becomes necessary. If a court finds these types of inventions to be unpatentable, or interprets them narrowly, the benefits of our strategy may not materialize and our business and financial condition could be significantly harmed.



Our rights to the use of technologies licensed to us by third parties are
not within our control, and without these technologies, our products and programs may not be successful and our business prospects could be harmed.



We rely, in part, on licenses to use certain technologies that are material to our business, including a secreted protein gene trap that
we license exclusively from the University of Edinburgh. We do not own the patents that underlie these licenses. Our rights to use these technologies and employ the inventions claimed in the licensed patents are subject to our licensors abiding by
the terms of those licenses and not terminating them. In many cases, we do not control the prosecution or filing of the patents to which we hold licenses. Some of the licenses under which we have rights, such as the license from the University of
Edinburgh, provide us with



29

##### Table of Contents

exclusive rights in specified fields, but we cannot assure you that the scope of our rights under these and other licenses will not be
subject to dispute by our licensors or third parties.



Our
activities involve hazardous material and may subject us to environmental liability, which would seriously harm our financial condition.



Our research and development activities involve the controlled use of hazardous and radioactive materials and generate biological waste.
We are subject to federal, state and local laws and regulations governing the storage, handling and disposal of these materials and waste products. Although we believe that our safety procedures for handling and disposing of these materials and
wastes comply with legally prescribed standards, the risk of accidental contamination or injury from these materials cannot be completely eliminated. We may be sued for any injury or contamination that results from our use or the use by third
parties of these materials, and our liability may exceed our insurance coverage and our total assets. Future environmental regulations could require us to incur significant costs.



Compliance with governmental regulations regarding animal welfare and genetically modified organisms could increase our
operating costs or adversely affect our customers ability to obtain governmental approval of gene based products, which would adversely affect the commercialization of our technology.



The Animal Welfare Act, or AWA, is the federal law that
currently covers animals in laboratories. It applies to institutions or facilities using any regulated live animals for research, testing, teaching or experimentation, including diagnostic laboratories and private companies in the pharmaceutical and
biotechnology industries. Rats, birds and mice, including the mice in our knockout programs, are currently excluded from the definition of animal and, therefore, are not subject to regulation under the AWA. However, the United States
Department of Agriculture, which enforces the AWA, has been sued on this matter and agreed, as part of the settlement of this lawsuit on September 25, 2000, to begin the process of changing the regulations issued under the AWA to include rats, mice
and birds within its coverage. Congress subsequently prohibited, in the Agricultural Appropriations Act for fiscal year 2001 and again for fiscal year 2002, the expenditure of any money or commencing rulemaking for the purpose of changing the
regulations with respect to including rats, mice and birds prior to October 1, 2002. We cannot predict whether mice will at any time after such date be included under the AWA.



Currently, the AWA imposes a wide variety of specific regulations which govern the humane handling, care,
treatment and transportation of certain animals by producers and users of research animals, most notably personnel, facilities, sanitation, cage size, feeding, watering and shipping conditions. We cannot assure you that the USDA will not in the
future include rats, mice and birds in its regulations and that we will not become subject to registration, inspections and reporting requirements. Compliance with the AWA could be expensive, and current or future regulations could impair our
research and production efforts.



Since we
develop animals containing changes in their genetic make-up, we may become subject to a variety of laws, guidelines, regulations and treaties specifically directed at genetically modified organisms, or GMOs. The area of environmental releases of
GMOs is rapidly evolving and is currently subject to intense regulatory scrutiny, particularly internationally. If we become subject to these laws we could incur substantial compliance costs. For example, the Biosafety Protocol, or the BSP, a
recently adopted treaty, is expected to cover certain shipments from the U.S. to countries abroad that have signed and ratified the BSP. The BSP is also expected to cover the importation of living modified organisms, a category that could include
our animals. If our animals are not contained as described in the BSP, our animals could be subject to the potentially extensive import requirements of countries that are signatories to the BSP.

Ethical and social issues
may limit or discourage the use of knockout mice or other genetic processes, which could reduce our revenues and adversely affect our business.



Governmental authorities could, for social or other purposes, limit the use of genetic processes or prohibit the practice of our gene trap
and knockout mouse technologies. Public attitudes may be influenced by claims that genetically engineered products are unsafe for consumption or pose a danger to the environment. The subject of genetically modified organisms, like knockout mice, has
received negative publicity and aroused public debate. In addition, animal rights activists could protest or make threats against our facilities, which may result in property damage. Ethical and other concerns about our methods, particularly our use
of knockout mice, could adversely affect our market acceptance.



Almost all of our knockout mouse research and storage is conducted at our San Francisco Bay Area facilities in San Carlos and Redwood City, and a natural disaster at one or more of these facilities is possible and could result in
a prolonged interruption of our business.



We conduct all of our scientific and management activities at our San Carlos and Redwood City facilities in California. These locations are in or proximate to seismically active areas. We have taken precautions to safeguard
our mouse colony including through insurance, the freezing of sperm and the storage of embryonic stem cells, or ES cells, to allow for the regeneration of mice. However, a natural disaster, such as an earthquake, fire, flood or outbreak of
infectious disease, could cause substantial delays. This could interrupt mouse breeding, cause us to incur additional expenses and adversely affect our reputation with customers.



Security risks in electronic commerce or unfavorable internet regulations may deter future use of our products and
services.



We do provide access to our gene
function database on the Internet. A fundamental requirement to conduct our business over the Internet is the secure transmission of confidential information over public networks. Advances in computer capabilities, new discoveries in the field of
cryptography or other developments may result in a compromise or breach of the security measures we use to protect the content in our gene function database. Anyone who is able to circumvent our security measures could misappropriate our proprietary
information or confidential customer information or cause interruptions in our operations. We may be required to incur significant costs to protect against security breaches or to alleviate problems caused by breaches, and these efforts may not be
successful. Further, a well-publicized compromise of security could deter people from using the Internet to conduct transactions that involve transmitting confidential information. For example, recent attacks by computer hackers on major e-commerce
web sites have heightened concerns regarding the security and reliability of the Internet.



Because of the growth in electronic commerce, the U.S. Congress has held hearings on whether to further regulate providers of services and transactions in the electronic commerce market, and federal
and state authorities could enact laws, rules and regulations affecting our business and operations. If enacted, these laws, rules and regulations could make our business and operations more costly and burdensome as well as less efficient.



We rely on third-party data sources, and without these
sources, our products and programs would be incomplete and less appealing to customers, seriously harming our business prospects.



We rely on scientific and other data supplied by third parties, and all of the gene sequence data for our internal programs comes from
public genomics data. This data could be defective, be improperly generated or contain errors or other defects, which could corrupt our gene function database and our other programs and services. In addition, we cannot guarantee that our sources
acquired this data in compliance with legal requirements. In the event of any such defect, corruption or finding of noncompliance, our business prospects could be adversely affected.

Our common stock may
continue to experience extreme price and volume fluctuations, which could lead to costly litigation for us and make an investment in us less appealing.



The market price of our common stock may continue to fluctuate substantially due to a variety of factors, including:



| |  |  | announcements of technological innovations or new products by us or our competitors;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | developments or disputes concerning patents or proprietary rights, including announcements with respect to infringement claims or lawsuits, interference proceedings,

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



Over the past two years our stock price has been, and in the future may be, highly volatile and could
continue to decline. Since the close of the quarter ended September 30, 2002, our stock has had minimum closing bid prices of less than $1.00 per share, which is the minimum bid price requirement for continued listing with the Nasdaq National
Market. Nasdaq may commence delisting proceedings and we may be delisted from the Nasdaq National Market. Our shares will continue to trade on the Nasdaq National Market unless and until the delisting proceedings have commenced and been completed
and the Nasdaq National Market has made a determination to delist us. In the event our shares are delisted from the Nasdaq National Market, we will attempt to have our common stock traded on the Nasdaq Small Cap Market. If our common stock is
delisted, it could seriously limit the liquidity of our common stock and would limit our potential to raise future capital through the sale of our common stock, which could seriously harm our business.



In addition, the stock market has experienced extreme price
and volume fluctuations. The market prices of the securities of biotechnology companies, particularly companies like ours without consistent product revenues and earnings, have been highly volatile and may continue to be highly volatile in the
future. This volatility has often been unrelated to the operating performance of particular companies. For example, the stock prices of many biotechnology companies, even those that would benefit from publicly available gene sequence information,
declined on news of the announcement by former President Clinton and British Prime Minister Blair that, as their respective governments had each advocated before, gene sequence information should be freely available in the public domain. In the
past, securities class action litigation has often been brought against companies that experience volatility in the market price of their securities. Whether or not meritorious, litigation brought against us could result in substantial costs, divert
managements attention and resources, and harm our financial condition and results of operations. Moreover, market prices for stocks of biotechnology-related and technology companies, particularly following an initial public offering,
frequently reach levels that bear no relationship to the operating performance of such companies. These market prices generally are not sustainable and are subject to wide variations.

The future sale of common
stock could negatively affect our stock price.



We had 40,986,893 shares of common stock outstanding at December 31, 2002.



If our common stockholders sell substantial amounts of common stock in the public market, or the market perceives that such sales may occur, the market price of our common stock could fall. The holders
of approximately 13.0 million shares of our common stock have rights, subject to some conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for
ourselves or other stockholders. Furthermore, if we were to include in a company-initiated registration statement shares held by those holders pursuant to the exercise of their registration rights, those sales could impair our ability to raise
needed capital by depressing the price at which we could sell our common stock.



In April 2003, we secured a minimum commitment for $10 million in equity capital from existing institutional investors to purchase preferred stock in a private placement. The private placement is
subject to shareholder approval and the satisfaction of closing conditions. In addition to the terms of the private placement, our stockholders will be asked to approve a number of other matters including a reverse stock split.



In connection with the private placement, we have agreed to
use reasonable best efforts, as soon as reasonably practicable after the closing of the private placement, to offer stockholders of record as of the last business day prior to the closing of the private placement (other than the investors in such
financing) non-transferable rights to purchase newly issued preferred stock at the same purchase price paid by the investors. The amount of preferred shares so offered to each stockholder would be sufficient to allow each such stockholder to
maintain the percentage ownership interest in Deltagen, held by each such stockholder as of the last business day prior to the closing of the private placement.



Our principal stockholders, executive officers and directors own a significant percentage of our stock, and as a result,
the trading price for our shares may be depressed and these stockholders can take actions that may be adverse to your interests.



As of December 31, 2002, our executive officers and directors, and entities affiliated with them, beneficially own, in the aggregate,
approximately 50.9% of our common stock. This significant concentration of share ownership may adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock in companies with controlling
shareholders. These stockholders, acting together, will have the ability to exert substantial influence over all matters requiring approval by our stockholders, including the election and removal of directors and any proposed merger, consolidation
or sale of all or substantially all of our assets. In addition, they could dictate the management of our business and affairs. This concentration of ownership could have the effect of delaying, deferring or preventing a change in control, or
impeding a merger or consolidation, takeover or other business combination that could be favorable to you.



Our incorporation documents and Delaware law may inhibit a takeover that stockholders consider favorable and could also limit the market price of your stock.



Our restated certificate of incorporation and bylaws contain
provisions that could delay or prevent a change in control of our company. Some of these provisions:



| |  |  | authorize the issuance of preferred stock which can be created and issued by the board of directors without prior stockholder approval, commonly referred to as
blank check preferred stock, with rights senior to those of common stock;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provide for a classified board of directors; and
| | - |  | ------------------------------------------------



| |  |  | prohibit stockholder action by written consent.
| | - |  | -----------------------------------------------



In addition, we are governed by the provisions of Section 203 of Delaware General Corporate Law. These provisions may prohibit large
stockholders, in particular those owning 15% or more of our outstanding voting

stock, from merging or combining with us. These and other provisions in our amended and restated certificate of incorporation and bylaws and
under Delaware law could reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.

In the fourth quarter of 2002, we substantially completed
animal and laboratory facility improvements in Redwood City, California, (700 Bay Road). We cancelled the construction of a new 50,000 square foot research facility in France.



We believe that our current facilities will be adequate for our current needs and that suitable additional
space or alternative space, if necessary, will be available in the future on commercially reasonable terms.



Item 3.    
Legal Proceedings



On May 24, 2000, Lexicon Genetics Incorporated filed a lawsuit against us in the United States District Court for the District of Delaware. The complaint in the lawsuit alleged that our methods of making knockout mice infringed
United States Patent No. 5,789,215, or the 215 patent, under which Lexicon claimed to be an exclusive licensee. In addition, on October 13, 2000, Lexicon and the University of Utah Research Foundation filed a lawsuit against us in the United
States District Court for the Northern District of California. The complaint in this lawsuit alleged that we infringed United States Patents Nos. 5,631,153, 5,464,764, 5,627,059 and 5,487,992, or the Capecchi patents, under which Lexicon claimed to
be an exclusive licensee. On September 20, 2001, we and Lexicon announced the settlement of the litigation. Under the terms of the settlement, we obtained a commercial license under the 215 patent and the Capecchi patents, Lexicon
obtained a subscription to our DeltaBase product, and all of the claims and counterclaims in the litigation were dismissed with prejudice. Lexicons subscription to DeltaBase includes non-exclusive, perpetual licenses to the 250 drug targets
represented in DeltaBase as of September 2001 and the approximately 1,000 drug targets that were and are expected to be added to DeltaBase over the subsequent four years. Lexicon will make certain milestone and royalty payments to us for therapeutic
and diagnostic products developed from Lexicons use of DeltaBase. We will make payments to Lexicon for knockout mice generated by us on a fee-for-service basis. Neither we nor Lexicon will pay the other party any subscription or license fees.

On April 28,
2003, we received from Lexicon a letter which Lexicon claims serves as notice of termination of the sublicense agreement under which we obtained a commercial license to the 215 patent and the Capecchi patents. In this letter, Lexicon specified
two grounds that allegedly entitles Lexicon to terminate the sublicense agreement: (1) our purported material breach of the DeltaBase agreement, under which Lexicon obtained a commercial license to our DeltaBase product; and (2) our purported
insolvency. On April 29, 2003, we received from Lexicon a letter which Lexicon claims serves as notice under the DeltaBase agreement of: (1) Lexicons alleged entitlement to damages in the amount of $25 million, plus attorneys fees and
costs, for our purported material breach of the DeltaBase agreement; and (2) alleged noncompliance with the content criteria in the DeltaBase agreement. We note that these letters from Lexicon follow shortly after our press release on April 4,
2003, in which we announced our receipt of a bridge loan and our efforts to obtain an equity financing. We believe that Lexicons claims and allegations are without merit, and intend to promptly address these claims according to the dispute
resolution procedures provided by the settlement and other agreements between Lexicon and Deltagen.



Deltagen is a party to two civil actions filed March 12, 2003 in the Superior Court of California, County of San Mateo, entitled Willow
Park Holding Company II v. Deltagen, Inc., Case No. 429871 (the Willow Park Action) and AMB Property, L.P. v. Deltagen, Inc., Case No. 429872 (the AMB Action). The plaintiff in the AMB Action is the owner of
real property located at 1210 and 1255 Hamilton Court, in Menlo Park, California. The plaintiff in the Willow Park Action is the owner of real property located at 1003 Hamilton Court, also in Menlo Park, California. We did not timely pay our rent on
the 1003 and 1210 Hamilton Court premises for March 2003, or our rent on the 1255 Hamilton Court premises for February and March 2003.



The complaints allege that we breached our leases for the three properties. In the AMB Action, the plaintiff seeks past due rent and
additional rent in the amount of $88,211, late charges in the amount of $8,821, and future rent and additional rent in the amount of $1,773,266. In the Willow Park Action, the plaintiff seeks past due rent and additional rent in the amount of
$75,946, late charges in the amount of $7,594, and future rent and additional rent in the amount of $921,898.



On March 14, 2003, the plaintiffs in both actions applied for an ex parte right to attach order, writ of attachment, and temporary
protective order. The plaintiff sought to attach $1,873,794 in the AMB Action, and $1,168,845 in the Willow Park Action. On March 14, 2003, the court granted the plaintiffs applications in part, and denied them in part. In the AMB Action, the
court ordered that the plaintiff has a right to attach our property in the amount of $97,032. In the Willow Park Action, the court ordered that the plaintiff has a right to attach our property in the amount of $83,541. The court also issued a
temporary protective order in each case, restricting us from transferring interests in specified property, and from disposing of the proceeds of any transfer of inventory. The temporary protective orders will expire no later than April 23, 2003. We
executed a Lease Termination Agreement with the plaintiffs effective March 31, 2003. Under this agreement the plaintiffs agreed to dismiss these actions promptly after June 30, 2003 except under certain circumstances as defined in the agreement.



We may be involved in additional litigation,
investigations or proceedings in the future. Any litigation, investigation or proceeding, with or without merit, could be costly and time-consuming and could divert our managements attention and resources, which in turn could harm our
business, financial position, and financial results and cash flows.

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



MANAGEMENTS DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS



You should read this report and the documents that we reference in this report completely and with the understanding that our actual
future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.



YOU SHOULD READ THE FOLLOWING DISCUSSION AND ANALYSIS IN CONJUNCTION WITH SELECTED CONSOLIDATED FINANCIAL DATA AND OUR
CONSOLIDATED FINANCIAL STATEMENTS AND THE ACCOMPANYING NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS.



Overview



Deltagen, founded in 1997, is a leader in using in vivo derived mammalian gene function information to define the function and disease relevance of mammalian genes for the purposes of discovering and validating novel drug
targets. Our proprietary information platform serves our pharmaceutical partners and customers in their efforts to discover potential new drug therapies.



Our products, based on our platform technology, provide databases of in vivo mammalian gene function information on target genes of
interest to drug researchers. We delete, or knock out, these genes in mice and then utilize an extensive, integrated analysis program to assess the function and potential pharmaceutical relevance of these genes and the proteins these
genes encode. We also focus our efforts to determine the function of secreted proteins. We are undertaking the discovery and development of biotechnology drug candidates in collaboration with other parties.



Our current customers and partners include many of the
worlds largest pharmaceutical companies, Eli Lilly and Company, GlaxoSmithKline plc, Merck & Co., Inc., Pfizer Inc., and Schering-Plough Research Institute, as well as significant biotechnology and biopharmaceutical companies including
Lexicon Genetics Incorporated, Millennium Pharmaceuticals, Nuvelo, Inc. and Tanox, Inc.



We also have the capability to conduct further target discovery and validation efforts through our Target Research and Development, or TRD, program. Our TRD program adds comprehensive in-depth analysis
to further characterize and identify potential key targets for the treatment of disease. The program currently focuses on the identification and validation of targets in metabolism and inflammatory diseases.



A principal goal of Deltagen is to validate and characterize
potential drug targets through our phenotypic analysis and TRD programs in an effort to further identify and validate potential drug candidates for our biopharmaceutical customers.



We are implementing a strategy to identify, validate and commercialize potential drug targets through our:



| |  |  | Target Research and Development program, an integrated systems biology infrastructure, comprising data generated from our platform of knockout animal models and
pathophysiological analysis, disease challenge models and biochemical disease pathway analysis;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | in vivo mammalian gene function and secreted protein discoveries;
| | - |  | -----------------------------------------------------------------



| |  |  | develop commercially relevant intellectual property on the use of mammalian genes and secreted proteins in drug development through alliances and collaborations with
third parties; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | generation of information, products and services for pharmaceutical and biotechnology drug discovery efforts.

Our recent
acquisition of XenoPharm, Inc. (XenoPharm,) further complements our target validation and characterization technologies. XenoPharm provides a proprietary technology platform to evaluate the metabolism of drug candidates, to improve the
predictive value of cell- and animal-based biomedical research and predict the reaction of a drug candidate in a human system, thereby screening candidates for improved chances of clinical success.



We believe that our ability to determine gene function, to
develop products and to identify and validate potential drug targets is a result of our leveraging of our technology platforms. Our genomics technologies, processes and information systems are integrated with one another and generate information on
the function and relationships between genes and the proteins these genes encode and the usefulness of genes as new drug targets and proteins as new drug candidates. We have used these systems to establish and develop our products and programs that
include our:



| |  |  | large-scale program to generate mammalian gene knockout animals and to discover gene function;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | DeltaBase portfolio of gene knockout animal models and mammalian gene function data analysis and management database;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | mammalian gene knockout secreted protein discovery collaborations and programs;
| | - |  | -------------------------------------------------------------------------------



| |  |  | Target Research and Development program, which adds additional gene knockouts, disease challenge models, and underlying disease pathway analysis to provide a
comprehensive systems biology approach to assist in identifying key targets for the treatment of disease;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | internal characterization, and evaluation of targets, including those targets discovered and analyzed using our proprietary in vivo mammalian functional
genomics programs; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | XenoPharms drug metabolism and xenobiotic technology platform to potentially predict the reaction of a drug in a human system.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



DeltaBase is our proprietary database that provides
information, based on knockout mouse studies, on gene function for drug discovery. We created DeltaBase to be marketed to the pharmaceutical and biotechnology industries to help define the role that genes play in biological processes and disease. We
select genes for DeltaBase based upon what we believe to be their potential to become useful drug targets. We generate information on these genes by comprehensively analyzing knockout mice generated through our proprietary gene knockout methods.
Each knockout mouse undergoes a standardized, detailed and extensive analysis in order to determine the function and role that a particular gene plays in the mouse. Additionally, DeltaBase subscribers will have access to the knockout mice used to
generate this data.



The DeltaSelect program was
our initial program. Customers received phenotypic target validation information for selected genes on a fee-for-service basis. This program was provided to validate our proprietary technology and promote interest in the DeltaBase product that
became available in 2000. We believe that the DeltaSelect program has provided validation of our proprietary platform technology and promoted interest in DeltaBase, however, the revenues generated from the DeltaSelect program have to date not been
significant and have with time become historically less significant. We anticipate that revenues from DeltaSelect will continue to become less significant and that DeltaSelect will be utilized only under very limited circumstances to develop new
technologies, product offerings and programs in collaboration with pharmaceutical companies.



We recently launched a product line known as DeltaOne that offers access to our extensive portfolio of knockout mice and/or accompanying phenotypic data, as well as any corresponding intellectual
property, on a gene-by-gene basis. Our current customers include Aventis Pharmaceuticals, Inc., Euroscreen, S.A. and Millennium Pharmaceuticals.



We have DeltaBase agreements with GlaxoSmithKline, Pfizer and Merck. Each of these agreements provides for payments aggregating
approximately $15 million in exchange for three years worth of DeltaBase

targets. In addition, we may receive additional fees for access to certain corresponding intellectual property. We began recognizing revenue
from the GlaxoSmithKline agreement in the fourth quarter of 2000. Revenue from the Pfizer agreement began to be recognized in the first quarter of 2001. We began to recognize revenue from the Merck agreement in the second quarter of 2002. We
anticipate that a significant portion of our revenues for at least the next six months will be derived from fees under agreements with DeltaBase subscribers and access to information and tools related to the DeltaBase product offering. Our current
DeltaBase agreements with GlaxoSmithKline and Pfizer are coterminous, each terminating upon our delivery of DeltaBase in June 2003, and, although renewable beyond such date, may not be renewed. The Merck agreement provides for payments on 600 genes
(through our delivery of DeltaBase in December 2002) with payments for the remaining 150 genes to be paid upon delivery of initial gene data that may be delivered to Merck subsequent to June 2003.



We also have secreted protein agreements with Eli Lilly and
Nuvelo.



Secreted Protein Agreements and
Collaborations



In August 2001, we entered
into a secreted protein agreement with Eli Lilly (Lilly) to evaluate, and potentially develop and commercialize, therapeutic secreted proteins. Under the terms of the agreement, Lilly has provided potential targets from its secreted
protein pipeline for which we will further evaluate the therapeutic potential in mammalian models. Among those secreted proteins with potential therapeutic value, each company may select proteins for commercial development, with each company
receiving royalties based on sales of therapeutic products. The agreement provides Lilly with certain acquisition, co-promotion, co-marketing and profit-sharing options with respect to therapeutic products developed and commercialized by us. The
agreement also provides us with certain co-promotion, co-development and profit-sharing opportunities.



In October 2001, we entered into a collaboration agreement with Nuvelo to research, develop and commercialize biopharmaceutical products
based on secreted proteins. Under the terms of the agreement, Nuvelo has provided us with gene sequences encoding secreted proteins and we will utilize our proprietary in vivo mammalian gene knockout technology to discover and validate
potential commercially relevant biopharmaceutical drug targets. We and Nuvelo will each have certain joint development and commercialization rights around potential biopharmaceutical drug targets discovered through the collaboration. We and Nuvelo
will share the collaborations costs; Nuvelo will provide us with approximately $8 million in research and development payments over two years. In addition, we received $10 million in equity proceeds from the sale of shares of our common stock
to George B. Rathmann, Ph.D., chairman of the Board of Directors of Nuvelo.



Revenue for the years ended December 31, is as follows (in thousands):

Under
our revenue recognition policy, revenues are recognized when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered and meet all customer-specified criteria, the price is fixed and determinable and
collectibility is reasonably assured. Revenue derived from DeltaBase agreements is recognized on a straight-line basis over the term in which services are to be provided. Research and development collaboration agreements specify milestones to be met
and the payments associated with meeting each milestone. Revenue derived from these contracts is recognized upon completion of the milestone. The amount of revenue recognized upon completion of each milestone is such that the earned revenue, as a
percentage of total anticipated revenue, approximates the costs incurred in achieving the related milestone, as a percentage of the total anticipated costs. Where the contract does not specify milestones and payment is upon completion of the



40

##### Table of Contents

contract, revenue is recognized based on the percentage-of-completion method of accounting. Any payments received in advance of the
completion of a milestone or services performed are recorded as deferred revenue.



We had net losses of $107.2 million, $48.5 million and $32.2 million in 2002, 2001 and 2000, respectively. The net loss attributable to common stockholders for the year ended December 31, 2000, was
$54.6 million, after deducting a dividend of $22.4 million relating to a beneficial conversion feature on our Series C redeemable convertible preferred stock. Our losses have resulted primarily from costs incurred in connection with
research and development activities, from selling, general and administrative costs associated with our operations and non-cash charges for amortization of unearned stock-based compensation costs and amortization of intangibles. Amortization totaled
$5.2 million and $4.5 million for the years ended December 31, 2002 and 2001, respectively. The year ended December 31, 2002 included a $28.9 million charge for the impairment of goodwill and other long-lived assets and restructuring
charges of $7.9 million. Research and development expenses consist primarily of salaries and related personnel costs, material costs, legal expenses resulting from intellectual property filings and other expenses related to the development of
our DeltaBase, DeltaSelect and secreted protein programs. We expense our research and development costs as they are incurred. Selling, general and administrative expenses consist primarily of salaries and related expenses for executive, finance and
other administrative personnel, professional and other corporate expenses including business development, marketing, litigation costs and general legal activities. In connection with the development and expansion of our gene function database and
our secreted protein program, we may incur research and development and selling, general and administrative costs that may exceed revenues. As a result, we may report net losses through the next several years.



We account for stock-based employee compensation arrangements
in accordance with provisions of Accounting Principles Board Opinion No. 25 (APB 25), Accounting for Stock Issued to Employees and related interpretations and comply with the disclosure provisions of Statement of Financial
Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based Compensation.



Under APB 25, compensation expense is based on the difference, if any, on the date of the grant, between the fair value of our stock and
the exercise price. SFAS 123 defines a fair value based method of accounting for an employee stock option or similar equity investment.



We account for equity instruments issued to non-employees in accordance with the provisions of SFAS 123 and Emerging Issues Task
Force Issue No. 96-18 (EITF 96-18), Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services and Financial Accounting Standards Board
Interpretation No. 28 (FIN 28), Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans.



During 2000, we recorded unearned stock-based compensation of approximately $12.0 million. This amount is being amortized as charges to
operations over the respective vesting period of the individual stock options, generally four years. During 2002 and 2001, we reversed approximately $1.0 million and $1.8 million of unearned stock-based compensation related to unvested stock
options due to employee terminations and changes in the fair market value of our common stock.



We may incur additional stock-based compensation expense in the future as a result of both options or other securities granted at below fair market value and fluctuations in the market value of our
stock that have a direct impact on the value of options and warrants held by non-employees.



We had federal net operating loss carryforwards as of December 31, 2002 and 2001, of approximately $150.4 million and $79.2 million, respectively. We had state net operating loss carryforwards as
of December 31, 2002 and 2001, of approximately $115.6 million and $79.2 million, respectively. We also had federal and state research and development tax credit carryforwards as of December 31, 2002 and 2001, of approximately
$10.7 million and $6.9 million, respectively. The net operating loss and credit carryforwards will expire at various dates beginning in 2005, if not utilized. Due to the uncertainty regarding the ultimate utilization



41

##### Table of Contents

of the net operating loss carryforwards, we have not recorded any benefit for losses, and a valuation allowance has been recorded for the
entire amount of the net deferred asset. Utilization of net operating losses and credits may be substantially limited due to the change in ownership provisions of the Internal Revenue Code of 1986 and similar state provisions. Certain future sales
of our stock could restrict our ability to utilize our net operating loss carryforwards. The annual limitation may result in the expiration of net operating losses and credits before utilization.



Critical Accounting Policies



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 financial statements requires
management to make estimates and judgments that affect the reported amounts of assets and liabilities, revenue and expenses and disclosures at the date of the financial statements. On an on-going basis, we evaluate our estimates, including those
related to accounts receivable, income taxes, impairment of long-lived assets, goodwill and intangible assets and restructuring liabilities. We use authoritative pronouncements, historical experience and other assumptions as the basis for making
estimates. Actual results could differ from those estimates.



We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.



We recognize revenue when there is pervasive evidence that an arrangement exists, delivery has occurred, the
price is fixed or determinable and collection is reasonably assured. We maintain an accounts receivable allowance for an estimated amount of losses that may result from customers inability to pay for product purchased. If the financial
condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.



We have established a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized.
Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using the enacted tax rates in effect for the year in which the differences are expected to affect
taxable income.



We perform goodwill impairment
tests on an annual basis and between annual tests in certain circumstances. The process of evaluating the potential impairment of goodwill is highly subjective and requires significant judgment at many points during the analysis. In estimating the
fair value of the businesses with recognized goodwill for the purposes of our fiscal 2002 consolidated financial statements, we made estimates and judgments about the future cash flows of these businesses. Our cash flow forecasts were based on
assumptions that are consistent with the plans and estimates we are using to manage the underlying businesses. In addition, we made certain judgments about allocating shared assets such as accounts receivable to the estimated balance sheet for those
businesses. We also considered our market capitalization on the dates of our impairment tests under SFAS 142, in determining the fair value of the respective businesses.



As required by SFAS 142, we performed our annual goodwill impairment test in the third quarter of 2002. As a
result of this impairment test, we recorded a goodwill impairment charge of $9.4 million.



We currently have three active restructuring plansone initiated in the fourth quarter of fiscal 2002 and the others initiated in the first and second quarters of fiscal 2003 after it became clear
that actions taken in the previous year would not be sufficient to turn the company profitable. The plans were designed to reduce costs and expenses in order to return the company to profitability.



The current accounting requirements for restructuring costs
requires us to record charges when we have incurred a liability. In connection with these plans, we have recorded estimated expenses for severance and



42

##### Table of Contents

outplacement costs, asset write-offs and other restructuring costs. Given the significance of, and the timing of the execution of such
activities, this process is complex and involves periodic reassessments of estimates made at the time the original decisions were made. We continually evaluate the adequacy of the remaining liabilities under our restructuring initiatives. Although
we believe that these estimates accurately reflect the costs of our restructuring plans, actual results may differ, thereby requiring us to record additional provisions or reverse a portion of such provisions.



Major Developments since December 31, 2001



Merck DeltaBase Agreement



On February 8, 2002, we entered into a license agreement to
provide Merck & Co., Inc. (Merck) with access to our proprietary DeltaBase product, a resource tool for the understanding of in vivo mammalian gene function information. Merck will have non-exclusive access to information
related to 750 genes selected for their biological interest that have been functionally characterized and entered into DeltaBase. Merck will also have access to certain of the corresponding DeltaBase intellectual property rights.



Closure of Arcaris, Inc.



On July 30, 2001, we acquired Arcaris, Inc.
(Arcaris). Located in Salt Lake City, Utah, Arcaris had developed technologies consisting of genetic, proteomic and cell-biological systems for identification and validation of drug targets and the creation of small molecule screens. The
total purchase price of approximately $8.0 million consisted of cash of approximately $450,000 and 766,894 shares of common stock valued at approximately $6.7 million and 77,329 vested stock options valued at approximately $418,000 and direct
acquisition costs of approximately $312,000. In October 2002, we issued an additional 94,095 shares of common stock valued at approximately $112,000 related to certain earn out provisions. The acquisition was accounted for using the purchase method
of accounting. The subsidiary was renamed Deltagen Proteomics, Inc.



On January 6, 2003, we announced a cost savings and business restructuring plan to reduce our cash expenditures. As part of this restructuring plan, we closed the Salt Lake City facility that housed the Deltagen Proteomics,
Inc. operations. As a result of the realignment plan, substantially all Deltagen Proteomics, Inc. activities and capabilities have ceased or been eliminated.



Acquisition and Closure of BMSPRL, L.L.C. (formerly CombiChem, Inc.)



On February 16, 2002, we acquired the California-based
BMSPRL, formerly known as CombiChem, Inc., from Bristol-Myers Squibb Company for 2,647,481 unregistered shares of our common stock valued at approximately $23.5 million and paid certain transaction expenses of approximately $465,000. The subsidiary
was renamed Deltagen Research Laboratories (DRL).



On October 2, 2002, we announced a cost savings and business restructuring plan to reduce our cash burn rate. As part of this restructuring plan, we closed the San Diego facility that housed the DRL operations. As a result of the
restructuring plan, substantially all DRL activities and chemistry capabilities have ceased or been eliminated.



Stanford Collaboration Agreement



On February 19, 2002, we announced that we had signed a target validation and research collaboration agreement with Stanford University.
Under the terms of the three-year collaboration, Stanford and the Company will mutually develop research projects for jointly selected genes under which we will provide Stanford non-exclusive access to knockout mice models using its proprietary
high-throughput technology and Stanford will evaluate and conduct research on such materials. We will have options to obtain exclusive licenses to

##### Table of Contents

commercially develop in any and all fields certain inventions developed by Stanford. We will have rights to use, commercialize and sublicense
results developed by Stanford under the research projects.



Acquisition of XenoPharm, Inc.



On March 14, 2002, we acquired XenoPharm, a San Diego, California-based private company for 498,236 shares of our unregistered common stock valued at approximately $3.6 million and paid certain transaction expenses. Up to an
additional 1,449,262 shares of common stock may be issued upon the achievement of certain key milestones. The entity became our wholly-owned subsidiary. XenoPharm, which was incorporated in November 2000, provides a proprietary technology platform
to pharmaceutical, biotechnology, chemical and agricultural companies to better understand and predict reactions of foreign substances, termed xenobiotics, in human systems. XenoPharms XenoSensor Mice, implanted with human SXR and
CAR, coupled with XenoPharms CleanScreen high-throughput screening assays provide a proprietary technology platform to improve the predictive value of cell- and animal-based biomedical research. The operating expenses of XenoPharm were
insignificant in 2002.



Restructuring
Activities



With the acquisitions of
Arcaris, Inc. and BMSPRL, L.L.C. and the expansion of our internal drug development efforts, the number of employees peaked at 450 by September 30, 2002 and we were leasing ten facilities. Given the significant net cash outflow from operations and
the difficulty in accessing additional capital, we undertook a series of cost cutting measures beginning in October 2002. These included workforce reductions in October 2002, January 2003 and April 2003 and the closure of our operations outside of
the San Francisco Bay Area, including the closure of Arcaris, BMSPRL and Europe operations. Remaining operations are being consolidated into our recently renovated 132,000 square foot facility in Redwood City, California. We discontinued our
internal drug discovery efforts and refocused our strategies and operations on providing drug discovery services to the biopharmaceutical industry utilizing the Companys proprietary core mammalian in vivo transgenic technologies. In
addition to the workforce reduction and cost cutting actions, we negotiated settlement of obligations with certain landlords, lenders and vendors.



Facility Leases



In March and April 2003, we entered into agreements with landlords or guarantors of several excess facilities in San Diego, California;
Menlo Park, California; Alameda, California; and Redwood City, California to terminate remaining lease obligations. Certain of the terminations are contingent on the closing of the Series A Preferred Stock financing described below. These
agreements require us to forfeit lease deposits or restricted cash underlying letters of credit totaling $2.5 million in 2003, make lease termination payments totaling $2.3 million in 2003 and $200,000 in 2004 and issue warrants to purchase
1,150,000 shares of our Series A Preferred Stock plus additional warrants equal to 0.05 warrants per dollar for each dollar of Series A preferred stock issued in excess of $10 million. The value of these settlements was expensed in 2002.



In addition, in April 2003 we entered into a
forbearance agreement related to the lease of our principal operating and administrative facility in Redwood City, California. This agreement provides for lease rent and certain facility operating expenses to be paid from the $1.5 million cash
security deposit or the $500,000 restricted cash related to letters of credit in 2003. Lease rent is also reduced by approximately 25% during the forbearance period. The agreement has certain default criteria that if breeched would cause the lease
rent to revert to prior levels retroactively.



Lending Arrangements



In March 2003, we repaid in full, without penalty, the outstanding balance of $10 million under a term loan facility. As a result of this payment, we are no longer required to maintain restricted cash balances of $10.5 million
as security for the loan facility.



44

##### Table of Contents



In March 2003,
we reached an agreement with a financial institution to restructure our existing loan agreements. The existing loan agreements had outstanding balances at March 15, 2002 of $5.0 million and were payable in monthly installments at interest rates
ranging from 8.87% to 12.75% with maturities to July 2005. Under the terms of the restructuring, we forfeited letters of credit totaling $2.3 million to the lender in partial payment of the loans and entered into a new loan for the remaining balance
of $2.7 million. The new loan will bear an interest rate of 10.50% and is required to be repaid in 18 monthly installments beginning in April 2003. The loan is collateralized by a first position security interest in certain fixed assets and a second
position security interest in substantially all of our other assets.



Vendor Arrangements



In April 2003, we settled a $1.2 million obligation with a vendor for $434,000 in current cash payments, $144,000 to be paid upon completion of the Series A Preferred Stock financing described below and $290,000 in Series A
Preferred Stock to be issued upon closing of the private placement. The remaining $290,000 balance is to be forgiven once the preferred financing is complete.



Bridge Loan and Commitment for Equity Financing



In April 2003, we secured a minimum commitment for $10 million in equity capital from existing institutional
investors to purchase preferred stock in a transaction referred to here in as the private placement. The private placement is subject to shareholder approval and the satisfaction of closing conditions. In addition to the terms of the private
placement, our stockholders will be asked to approve a number of other matters including a reverse stock split.



Under the terms of the private placement, the investors have agreed to purchase $10 million of preferred stock. The preferred stock is
convertible into common stock on a 1:1 basis. The preferred stock will be issued at a 25% discount to the five-day average closing common stock price for the period ending three days prior to closing. The preferred stock bears no dividend, has a
liquidation preference right equal to the amount invested in the preferred stock and standard anti-dilution protections. The terms of the preferred stock agreement include the right to appoint designees to a total of three seats on the Board of
Directors.



We also obtained a secured bridge
loan commitment of $5 million from the same investors. This facility can be increased to $6 million upon the occurrence of certain events and milestones and is secured by all of our assets not pledged to the equipment loans. The loan bears interest
at 10% per annum. The principal and interest on the bridge loan will be repaid upon the earlier of the closing of the private placement with the proceeds thereof or August 31, 2003.



In connection with the private placement, we have agreed to use reasonable best efforts, as soon as
reasonably practicable after the closing of the preferred stock financing, to offer stockholders of record as of the last business day prior to the closing of the private placement (other than the investors in such financing) non-transferable rights
to purchase newly issued preferred stock at the same purchase price paid by the investors. The amount of preferred shares so offered to each stockholder would be sufficient to allow each such stockholder to maintain the percentage ownership interest
in Deltagen held by each such stockholder as of the last business day prior to the closing of the private placement.

Years Ended December
31, 2002 and 2001



Revenues



Contract revenue increased by $7.8 million to $17.7 million
in 2002 from $9.9 million in 2001. The increase was due primarily to increased revenue from our DeltaBase gene function database product. DeltaBase revenue in 2002 was $15.0 million compared to $8.6 million in 2001. In 2002, our DeltaBase, DeltaOne
and DeltaSelect revenue came principally from contracts with GlaxoSmithKline, Merck, Millennium Pharmaceuticals, Pfizer and Schering-Plough Research Institute.



Costs and Expenses



Costs and expenses for the year ended December 31, 2002 were $125.5 million compared to $62.1 million in 2001. Costs and expenses for
the year ended December 31, 2002 include charges of $36.8 million for restructuring charges and the impairment of goodwill and other assets. These charges are associated with our strategic business realignments announced in October 2002 and
January 2003 and include severance costs; impairment charges for goodwill, intangibles and fixed assets. We will record additional charges for severance and other employee related costs, lease related costs and other asset disposal costs related to
the January 2003 operating reductions in the first quarter of 2003. Further charges will be recorded in the second quarter of 2003 for the cost reduction actions announced on April 10, 2003.

##### Table of Contents



Excluding the
restructuring and impairment charges, costs and expenses for the year ended December 31, 2002 were $88.7 million, compared to $62.1 million in 2001. Also excluding non-cash charges for depreciation, amortization of intangibles and amortization
of unearned stock compensation, costs and expenses for 2002 were $77.3 million, including $18.1 million in costs for operations that have subsequently been closed, compared to $53.6 million in 2001. The increase in costs and expenses was
due primarily to the increased costs of our internal drug discovery efforts following the acquisition of chemistry capabilities in February 2002. These internal drug discovery efforts were reduced in the October 2002 business restructuring and
discontinued following the January 2003 workforce reductions.



Research and development expenses before non-cash charges increased by $23.4 million to $61.3 million in 2002 from $37.9 million in 2001. This increase included $11.5 million in costs associated with the BMSPRL (Deltagen
Research Laboratories or DRL) operations acquired in February 2002 and substantially closed down by December 31, 2002. In addition, research and development expenses in 2002 before non-cash charges included $4.5 million from the Deltagen
Proteomics and Deltagen Europe operations that were closed down in the first quarter of 2003. The related costs from these operations were $1.2 million in 2001. The remaining increase in costs and expenses is due primarily to the ramp-up during 2002
of our now discontinued internal small molecule drug discovery efforts and costs associated with our secreted protein programs with Eli Lilly and Nuvelo. The increase in depreciation and amortization is due primarily to an increase in property,
plant and equipment resulting from the acquisition of BMSPRL. The increase in intangible amortization is due to the acquisition of BMSPRL in February 2002 and XenoPharm in March 2002.



General and administrative expenses before non-cash charges increased by $400,000 to $16.1 million in
2002 from $15.7 million in 2001. This increase included $700,000 in costs associated with the DRL operations acquired in February 2002 and substantially closed down by December 31, 2002. In addition, general and administrative expenses in 2002
before non-cash charges included $1.4 million from the Deltagen Proteomics and Deltagen Europe operations that were closed down in the first quarter of 2003. The related costs from these operations were $1.1 million in 2001. The increase also
included $1.0 million related to staffing and infrastructure costs offset by a decrease of $2.8 million related to legal and business consulting fees.



Impairment of Goodwill and Other Long-Lived Assets



Due to current operating losses, the absence of positive cash flows, recent significant declines in our common stock price and
uncertainties resulting from the business restructuring plan, we assessed the recoverability of the long-lived assets related to DRL and Arcaris in accordance with SFAS 144 and tested goodwill for impairment in accordance with SFAS No. 142 during
the year ended December 31, 2002. Based upon our projection of significantly reduced future cash flows related to the long-lived assets, an impairment loss of $7.1 million was recognized for completed technology and $12.4 million for property and
equipment during the year ended December 31, 2002. The carrying value of the long-lived assets has been written down to expected fair value based on appraisals. The impairment test under SFAS 142 was based on a two-step process involving; comparing
the estimated fair value of the related reporting unit to its net book value and comparing the estimated implied fair value of goodwill to its carrying value. As a result of the test, we wrote down goodwill by $9.4 million in the year ended December
31, 2002.



Restructuring Charges



In 2002 we recorded restructuring charges
of $7.9 million. These charges include the following (in thousands):



|Retention bonuses, severance and executive compensation |  | $ | 4,333
|------------------------------------------------------- |  | - | -----
|Legal, accounting and consulting fees                   |  |   | 493

These charges
relate primarily to the closedown of the DRL operations and workforce reductions in 2002.



Net Interest Income



Net interest income decreased by $3.0 million to $687,000 in 2002 from $3.7 million in 2001. This decrease resulted from reduced average cash and investment balances, lower interest rates on cash investments and increased borrowings
during 2002 and as compared to 2001.



Years Ended December 31,
2001 and 2000



Contract revenue increased by
$7.8 million to $9.9 million in 2001 from $2.1 million in 2000. The increase was due primarily to increased revenue from our DeltaBase gene function database product. DeltaBase revenue in 2001 was $8.6 million compared to $1.2 million in 2000. In
2001, all of our DeltaBase and DeltaSelect revenue came from contracts with GlaxoSmithKline, Merck, Pfizer, Schering-Plough Research Institute and Tularik, Inc.



Research and development expenses increased by $18.7 million to $45.0 million in 2001 from $26.3 million in
2000. The increase was attributable to continued growth of research and development activities, including $15.1 million related to increased personnel and laboratory supply costs to support development of our gene function database and our
DeltaSelect and secreted protein programs and $6.5 million in higher depreciation and amortization and facilities expenses related to the addition of facilities in 2001. The amortization of unearned stock-based compensation decreased by $3.0 million
to $2.9 million in 2001 from $5.9 million in 2000.



General and administrative expenses increased by $5.9 million to $17.0 million in 2001 from $11.1 million in 2000. The increase included $5.3 million related to staffing and infrastructure costs, $3.7 million related to legal and
business consulting fees and $1.1 million in higher depreciation and amortization and facilities expenses related to the addition of facilities in 2001. The amortization of unearned stock-based compensation decreased by $4.0 million to $1.0 million
from $5.0 million in 2000.



Net interest income
increased by $675,000 to $3.7 million in 2001 from $3.0 million in 2000. This change resulted from increased average cash and investment balances during 2001 as a result of the completion of our initial public offering during the third quarter of
2000 partially offset by lower interest rates on cash investments.



Business Restructuring



On October 2, 2002, we announced a business restructuring and plan to reduce expenses. Our business strategy will focus on tools, services and targets for the discovery and development of small molecule drugs. These products and
services will be marketed to drug researchers in the biopharmaceutical industry. We also expect to continue to pursue our internal drug discovery and development in secreted proteins through current and potential future collaborations.



As part of this restructuring, we reduced our staff by over
130 employees. The plan includes the closing of our San Diego operations acquired in the acquisition of the DRL operations, the planned exit from our operations in Europe and the planned consolidation of core activities into our Redwood City,
California and Salt Lake City, Utah facilities.



As result of these actions, we recorded a charge in 2002 for impairment of the intangible assets related to activities that will no longer be pursued or that will be scaled back, for the impairment of fixed assets including leasehold
improvements and equipment, for severance and other employee related costs and restructurings and other costs. These costs and impairments relate primarily to our operations in San Diego (DRL acquired in 2002), Salt Lake City (Arcaris acquired in
2001) and Europe.

It is
anticipated that a majority of the remaining accrual will be paid during fiscal year 2003.



On January 6, 2003, we announced additions to the business restructuring and cost reduction plan.



As part of this restructuring, we reduced our staff to approximately 200 employees. The plan included the closing of our Strasbourg,
France operations and our Salt Lake City operations acquired in the acquisition of Arcaris, Inc., as discussed in Note 18, and the consolidation of core activities into our Redwood City, California facility.



We will record a charge in the first quarter of 2003 for
severance and other employee related costs, costs associated with lease obligations and other costs. These costs relate primarily to the Companys operations in Strasbourg, France, Salt Lake City, Utah (Arcaris acquisition in 2001) and excess
facilities in Alameda and Menlo Park, California.



We will record a charge in the second quarter of 2003 for severance and other employee related costs associated with a further reduction in the workforce to approximately 150 employees announced on April 10, 2003.



In March and April 2003, we executed termination agreements
for several excess facilities, including our sites in Menlo Park, Alameda, San Diego and one site in Redwood City, California. These agreements are contingent on a $10 million equity financing being completed before August 31, 2003. We also entered
into a forbearance agreement for a principal operating and administrative facility in Redwood City, California that will result in reductions in rent payments as long as designated termination events are not triggered. If the private placement is
completed and the forbearance reductions continue, the remaining lease obligations will be as follows (in thousands):

Liquidity and Capital
Resources



We have financed our operations
from inception primarily through issuances of equity securities, contract payments to us under our DeltaSelect and DeltaBase agreements and equipment financing arrangements. Through December 31, 2002, we had received net proceeds of $183.4 million
from issuances of equity securities, $43.3 million from customer agreements, $12.7 million from equipment financing arrangements and $10 million from a term loan facility.



At December 31, 2002, we had $7.7 million in cash and cash equivalents compared to $61.4 million at December
31, 2001. In addition, at December 31, 2002, we had $6.1 million in marketable securities representing highly liquid commercial paper and government agency securities compared to $15.1 million at December 31, 2001. We used $59.5 million in cash for
operating activities in 2002. This consisted primarily of the net loss for the period of $107.2 million offset in part by non-cash charges totaling $40.3 million including $9.4 million for goodwill impairment, $19.5 million for fixed assets and
intangible assets impairment, $6.2 million related to depreciation and amortization expenses, $3.8 million related to the amortization of intangibles and $1.4 million related to the amortization of unearned stock-based compensation. Increases in
deferred revenue and accrued liabilities were partially offset by increased customer receivables and restriction of cash to support debt obligations. Investment activities used $29.2 million in cash in 2002 including $11.3 million related to the
purchase of marketable securities, $23.5 million related to capital expenditures (primarily for the build out of our vivarium, laboratory and administrative facility in Redwood City, California) and $981,000 related to the acquisitions of the DRL
operations and XenoPharm, Inc. in February and March 2002, respectively, offset in part by $20.0 million related to the maturities of marketable securities. We received $35.0 million in cash from financing activities in 2002, which consisted
primarily of $14.0 million from loan proceeds and $25.6 million from the sale of common stock. This was offset partially by loan and capital lease repayments of $4.6 million.



In December 1998, March 1999, June 2000 and June 2001, we entered into loan agreements of $1.8 million, $1.5
million, $2.9 million and $2.5 million, respectively, which were fully drawn down during 1999, 2000 and 2001. As of December 31, 2002, the entire $5.5 million outstanding balance was collateralized by property and equipment. Amounts outstanding
under these loans accrued interest at a weighted average rate of approximately 10.55% and are due in monthly installments through 2005. The loans are collateralized by property and equipment. In October 2002, we provided letters of credit for $2.3
million to the lender as additional collateral for these and other equipment loans.



At December 31, 2002 we had the following contractual cash obligations (including operating lease obligations that were restructured pursuant to our business realignment discussed above) (in
thousands):

We have issued standing letters of credit totaling $3.0 million and security deposits of $1.5 million as credit support for operating
leases. These letters of credit are collateralized by cash deposits of an equal amount and automatically renew on an annual basis during the lease term. These cash deposits are classified as restricted cash

on the consolidated balance sheets. We expect that substantially all of these letters of credit and deposits will be paid to landlords in the
first half of 2003 as part of settlement consideration for lease termination and lease reduction arrangements.



The equipment loan agreements have restrictive covenants requiring minimum unrestricted cash balances, generally twelve months cash needs.
In October 2002, we provided letters of credit for $2.3 million as additional collateral for the equipment loans. There are no further collateral requirements contingently required under these loans. This loan was amended in April 2003 and the
restricted cash supporting the letter of credit was released as prepayment of the debt obligation.



The term loan agreement has restrictive covenants including a requirement that we maintain unrestricted cash balances, as defined, equal
to the greater of two times the principal balance outstanding on the loan or six months of net cash used in operating activities. If unrestricted cash balances fall below the minimum level, we will be required to restrict cash equal to 105% of
the loan balance outstanding or pay down the loan balance to a level that achieves compliance with the restrictive covenants. At October 31, 2002, our unrestricted cash balances were below the minimum level and we provided restricted cash of $10.5
million as collateral for the term loan facility. On March 6, 2003, we repaid the loan in full without penalty and the remaining restricted cash was released.



At December 31, 2001, we had approximately $6.2 million in committed financing available for the construction of a research and
development facility for Deltagen Europe S.A. In October 2002, we cancelled the construction project and the committed financing has been withdrawn.



At December 31, 2002, we had unrestricted cash, cash equivalents and marketable securities totaling $13.8 million.



Our immediate sources of cash for operating activities are:



| |  |  | existing customer agreements;
| | - |  | -----------------------------



| |  |  | potential new customer agreements;
| | - |  | ----------------------------------



| |  |  | proceeds from liquidation of assets from closed facilities (primarily assets from the Arcaris, Inc. acquisition) and exited activities. These proceeds totaled
approximately $852,000 subsequent to December 31, 2002; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | XenoPharm continues to incur legal expenses in connection with its patent applications and the patent applications of its licensors. It is expected that these
expenses will increase as the level of patent prosecution increases.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Our immediate requirements for cash include:



| |  |  | ongoing operating expenses (research and development costs and selling, general and administrative expenses);
| | - |  | -------------------------------------------------------------------------------------------------------------



| |  |  | completion of our Redwood City, California animal facility and laboratory expansion (completed in February 2003); and
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | costs associated with the business realignment including severance and other employee related costs, facility closedown costs and lease and lease termination costs
associated with excess facilities under long-term leases.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



At March 31, 2003, the balance of cash and cash equivalents was approximately $2.5 million. In April 2003, we received $5 million in proceeds from a bridge loan and received a commitment from investors to purchase a minimum
$10 million in newly issued preferred stock. The bridge loan can be increased to $6 million upon the

occurrence of certain events and milestones and is collateralized by all of our assets not pledged to the equipment loan. Principal and
interest on the loan is to be repaid upon the earlier of the closing of the preferred financing with the proceeds thereof or August 31, 2003.



If we are not able to complete the private placement on time, it is likely that we will cease our operations. Our inability to obtain
additional funding through the private placement would likely cause us to explore liquidation alternatives, including the initiation of bankruptcy proceedings. If this were to occur, after repayment of our obligations including the bridge loan
received from the private placement investors, any investment in us would likely decline to zero.



The equity financing is subject to shareholder approval and the satisfaction of closing conditions. There are financial covenants to the
bridge loan associated with cash and earnings before interest, taxes, depreciation and amortization (EBITDA) performance versus forecast which if not met could lead to loan default and acceleration of the loan. In order to have
sufficient cash to operate in 2003 we may be required to further reduce the level of operating expenses through additional workforce reductions and access additional debt or equity capital. We continue to evaluate alternative means of financing to
meet our long-term needs; however, additional financing may not be available on terms acceptable to us or at all. The sale of additional equity or convertible debt securities may result in substantial additional dilution to our stockholders. Any
debt financing may have restrictive covenants that adversely affect our operating plans and flexibility.



We continue to evaluate alternative means of financing to meet our needs on terms that are attractive to us. Although we have recently
implemented a business realignment and staff reductions to reduce our cash burn rate, if we are not able to obtain needed capital, we will have to take additional actions to conserve our cash balances, including further reductions in our operating
expenses, downsizing of our staff and closing of facilities, all of which would likely have a material adverse effect on our business, financial condition and our ability to reduce losses or generate profits.



We have not paid any cash dividends on our common stock in the
past. We currently intend to retain any earnings for use in the business and do not anticipate paying any cash dividends on our common stock in the foreseeable future.



Recent Accounting Pronouncements



In August 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial
Accounting Standards No. 143 (SFAS 143), Accounting for Asset Retirement Obligations, which is effective for fiscal years beginning after June 15, 2002. SFAS 143 addresses financial accounting and reporting for obligations
associated with the retirement of tangible long-lived assets and the associated asset retirement costs. SFAS No. 143 requires, among other things, that the retirement obligations be recognized when they are incurred and displayed as liabilities on
the balance sheet. In addition, the assets retirement costs are to be capitalized as part of the assets carrying amount and subsequently allocated to expense over the assets useful life. We believe that the adoption of SFAS 143
will not have a material effect on our financial position or results of operations.



In April 2002, the FASB issued Statement of Financial Accounting Standards No. 145 (SFAS 145), Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and
Technical Corrections, which is effective for fiscal years beginning after May 15, 2002. Under SFAS 145, gains and losses from the extinguishment of debt should be classified as extraordinary items only if they meet the criteria of Accounting
Principles Board Opinion No. 30. SFAS also addresses financial accounting and reporting for capital leases that are modified in such a way as to give rise to a new agreement classified as an operating lease. We believe that the adoption of SFAS 145
will not have a material effect on our financial position or results of operations.

In June 2002,
the FASB issued Statement of Financial Accounting Standards No. 146 (SFAS 146), Accounting for Costs Associated with Exit or Disposal Activities, which is effective for exit or disposal activities initiated after December 31,
2002. SFAS 146 nullifies Emerging Issues Task Force Issue No. 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). Under
SFAS 146, a liability is required to be recognized for a cost associated with an exit or disposal activity when the liability is incurred. SFAS 146 applies to costs associated with an exit activity that does not involve an entity newly acquired in a
business combination or with a retirement or disposal activity covered by FASB Statements No. 143 and 144. We elected early adoption of SFAS 146 in 2002 in conjunction with the business realignment discussed above. We recorded a charge of $7.9
million in 2002 for severance and other employee related costs, costs associated with lease obligations and restructurings and other costs.



In November 2002, the FASB issued FASB Interpretation No. 45 (FIN 45), Guarantors Accounting and Disclosure
Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. FIN 45 requires that a liability be recorded in the guarantors balance sheet upon issuance of a guarantee. In addition, FIN 45 requires
disclosures about the guarantees that an entity has issued, including a reconciliation of changes in the entitys product warranty liabilities. The initial recognition and initial measurement provisions of FIN 45 are applicable on a
prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantors fiscal year-end. The disclosure requirements of FIN 45 are effective for financial statements of interim or annual periods ending after
December 15, 2002. We believe that the adoption of FIN 45 will not have a material impact on our financial position or results of operations.



In November 2002, the Emerging Issues Task Force (EITF) reached a consensus on Issue No. 00-21 (EITF 00-21),
Revenue Arrangements with Multiple Deliverables. EITF 00-21 provides guidance on how to account for arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets. The provisions of EITF
00-21 will apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003. We believe that the adoption of EITF 00-21 will not have a material impact on our financial position or results of operations.



In December 2002, the FASB issued Statement of Financial
Accounting Standards No. 148 (SFAS 148), Accounting for Stock-Based Compensation, Transition and Disclosure. SFAS 148 provides alternative methods of transition for a voluntary change to the fair value based method of
accounting for stock-based employee compensation. SFAS 148 also requires that disclosures of the pro forma effect of using the fair value method of accounting for stock-based employee compensation be displayed more prominently and in a tabular
format. Additionally, SFAS 148 requires disclosure of the pro forma effect in interim financial statements. The transition and annual disclosure requirements of SFAS 148 are effective for fiscal years ended after December 15, 2002. The interim
disclosure requirements are effective for interim periods beginning after December 15, 2002. The adoption of SFAS 148 did not have a material impact on our financial position or results of operations.



In January 2003, the FASB issued FASB Interpretation No. 46
(FIN 46), Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51. FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary of the entity if the equity investors in
the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 is
effective immediately for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or
annual period beginning after June 15, 2003. We are currently evaluating the impact, if any, that the adoption of FIN 46 will have on our financial position or results of operations.

7A.Quantitative and Qualitative Disclosures About Market Risk



We invest our excess cash primarily in obligations of governmental agencies and marketable debt securities of financial institutions and
corporations with strong credit ratings. These instruments have maturities of twenty- four months or less when acquired. We do not utilize derivative financial instruments, derivative commodity instruments or other market risk sensitive instruments,
positions or transactions in any material fashion. Accordingly, we believe that, while the instruments we hold are subject to changes in the financial standing of the issuer of such securities, we are not subject to any material risks arising from
changes in interest rates, foreign currency exchange rates, commodity prices, equity prices or other market changes that affect market risk sensitive instruments.



Our loans payable of $15.6 million at December 31, 2002 carry fixed interest rates ranging from 8.87% to
12.75% per annum with payments due in 36 or 48 monthly installments. Our capital lease obligations of $27,000 at December 31, 2002 carry fixed interest rates ranging from 0% to 10.39% per annum with payments due in 36 monthly installments.
At October 31, 2002, our unrestricted cash balances were below the minimum level and we provided restricted cash of $10.5 million as additional collateral for the loan. The interest rate of the $10 million loan payable was reduced to the prime
rate (currently 4.25%) in November 2002. On March 6, 2000, we repaid the loan in full without penalty and the remaining restricted cash was released.



The following table presents, as of December 31, 2002, the future principal amounts and related weighted average interest rate by year for
our cash and cash equivalents, marketable securities and debt obligations (in thousands).

|Weighted average interest rate |  |                                                 



Prior to
February, 2001 we operated solely in the United States. Beginning February 15, 2001, our European subsidiary, Deltagen Europe S.A. began operations. The expenses of these European operations have not been material and all sales of our products to
date have been made in U.S. dollars. Accordingly, we have not had any material exposure to foreign currency rate fluctuations.

REPORT OF INDEPENDENT ACCOUNTANTS



To the Board of Directors and Stockholders

of Deltagen, Inc.:



In
our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Deltagen, Inc., and its subsidiaries at December 31, 2002 and 2001, and the results of their
operations and their cash flows for each of the three years in the period ended December 31, 2002 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of
the Companys management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States
of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, 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.



The accompanying consolidated financial statements
have been prepared assuming the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and operating cash flow deficiencies that raise
substantial doubt about its ability to continue as a going concern. Managements plans in regards 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.

INC.



NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



1.    FORMATION AND BUSINESS OF THE COMPANY



Deltagen, founded in 1997 and headquartered in Redwood City, California, is a leader in using in vivomammalian gene function information to define the function and disease relevance of
mammalian genes for the purpose of discovering and validating novel drug targets. The Companys proprietary information platform serves the Companys customers in their efforts to discover potential new drug therapies.



Basis of Presentation



The Companys commercial operations commenced during
2000 at which time it emerged from the development stage. The Company has incurred net losses since inception of $206,300,000 and may incur net losses and negative cash flow from operations for at least the next several years. These matters raise
substantial doubt about the Companys ability to continue as a going concern. Managements plans include increasing sales by refocusing on providing drug discovery services to the biopharmaceutical industry and reducing cash spending
during fiscal year 2003 as a result of continued down sizing of the Company and elimination of the Companys internal small molecule drug discovery programs. These reduction efforts began in the third quarter of fiscal year 2002 and have
continued into 2003 and are expected to significantly reduce the future cash outflows. Management also recognizes the need for an infusion of cash during the year ended December 31, 2003. In April 2003, the Company received a minimum commitment for
$10 million in equity capital from existing institutional investors, subject to shareholder approval and the satisfaction of closing conditions. The Company will finance its operations primarily through its cash and cash equivalents, marketable
securities and future revenues. The Company expects to require additional funding and may sell additional shares of its common or preferred stock through private placements or further public offerings, or it may seek additional credit facilities.
The sale of additional equity or debt securities may result in additional dilution to existing stockholders. If additional funds are raised through the issuance of equity or debt securities, these securities could have rights that are senior to
existing stockholders and could contain covenants that would restrict operations. Any additional financing may not be available in amounts or on terms acceptable to the Company, if at all.



While the Company is aggressively pursuing the actions discussed above, there can be no assurance that the
Company will be successful in its efforts to achieve future profitable operations, generate sufficient cash from operations or obtain additional funding sources. The financial statements do not contain any adjustments that might result from the
outcome of this uncertainty.



2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES



Basis of Consolidation



The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.



Use of Estimates



The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures 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.



Concentration of Credit Risk and Major Customers



Cash, cash equivalents and marketable securities are held in two financial institutions. Management regularly reviews these financial
institutions for creditworthiness. By policy, the Company limits concentration of credit risk by diversifying its investments among a variety of high-quality credit issuers.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)





The
Companys accounts receivable relate to contracts, and there is no collateral required for these accounts receivable. In 2002, four customers individually accounted for 22%, 35%, 25% and 10% of the Companys total revenue and accounted for
32%, 24%, 15% and 15% of the net accounts receivable balance at December 31, 2002. In 2001, two customers individually accounted for 46% and 41% of the Companys total revenue. At December 31, 2001, two customers accounted for 37% and 58%
of the net accounts receivable balance. In 2000, two customers individually accounted for 56% and 18% of the Companys total revenue.



Certain Risks and Uncertainties



The Companys services are concentrated in highly competitive markets that are characterized by rapid technological advances,
frequent changes in customer requirements and evolving regulatory requirements and industry standards. Any failure by the Company to anticipate or to respond adequately to technological developments in its industry, changes in customer requirements
or changes in regulatory requirements or industry standards, or any significant delays in the development or introduction of services could have a material adverse effect on the Companys business and operating results.



Fair Value of Financial Instruments



Carrying amounts of certain of the Companys financial
instruments, including cash and cash equivalents, marketable securities, accounts receivable, accounts payable and accrued liabilities approximate fair value due to their relatively short maturities. Based upon borrowing rates currently available to
the Company for loans and capital leases with similar terms, the carrying value of its debt and capital lease obligations approximate fair value.



Cash and Cash Equivalents and Restricted Cash



Investments with an original maturity of 90 days or less as of the date of purchase are considered cash equivalents. Cash equivalents
consist of money market funds, corporate debt securities and obligations of governmental agencies. Restricted cash consists of certificates of deposit held with financial institutions as security deposits for various building leases and letters of
credit.



Marketable Securities



The Company has classified its marketable securities as
available-for-sale and they are carried at amortized cost which approximates fair value. Interest income is recorded using an effective interest rate, with the associated premium or discount amortized to interest income.
Unrealized gains and losses are reported net of related taxes as a separate component of stockholders equity until realized. Realized gains and losses on sales of all such securities are reported in earnings and computed using the specific
identification method.



Property, Plant and Equipment



Property, plant and equipment are stated at
cost, net of accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful life of the asset; seven years for laboratory equipment, three years for computer equipment and six years for
furniture and fixtures. Leasehold improvements and property, plant and equipment under capital leases are amortized over the lesser of their estimated useful lives or the term of the lease. Upon retirement or sale, the cost and related accumulated
depreciation are removed from the accounts and any related gain or loss is reflected in operations. Maintenance and repairs are charged to operations as incurred.

Goodwill and other
intangible assets



Goodwill and other
intangible assets primarily consist of goodwill and purchased technology. The amount allocated to completed technology is being amortized over the estimated useful life of three to ten years using the straight-line method. Goodwill will not be
systematically amortized, but rather the Company will perform an assessment for impairment at least annually by applying a fair-value-based test. During the year ended December 31, 2002, the Company recorded an impairment loss of approximately
$7,103,000 on intangible assets and approximately $9,372,000 on goodwill (Note 10).



Impairment of Long-Lived Assets



The Company periodically reviews the value of long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset might not be recoverable or that the useful lives of an asset is
no longer appropriate. When such an event occurs, management determines whether there has been an impairment by comparing the anticipated undiscounted future net cash flows to the related assets carrying value. If an asset is considered
impaired, the asset is written down to fair value, which is determined based either on discounted cash flows or appraised values, depending on the nature of the asset. During the year ended December 31, 2002, the Company recorded a loss on
impairment of fixed assets of approximately $12,418,000 (Note 10).



Foreign currency



The
Company uses the U.S. dollar as the functional currency for all of its foreign subsidiaries. Accordingly, gains and losses from translation of foreign currency financial statements into U.S. dollars are included in results of operations. The effect
of foreign currency exchange rate fluctuations was not material for all periods presented.



Income Taxes



The Company accounts for income taxes under 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
liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.



Revenue Recognition



Revenues are recognized when persuasive evidence of an
arrangement exists, delivery has occurred or services have been rendered and meet all customer-specified criteria, the price is fixed and determinable and collectibility is reasonably assured. Revenue derived from DeltaBase agreements is recognized
on a straight-line basis over the term in which services are to be provided. Research and development collaboration agreements specify milestones to be met and the payments associated with meeting each milestone. Revenue derived from these contracts
is recognized upon completion of the milestone. The amount of revenue recognized upon completion of each milestone is such that the earned revenue, as a percentage of total anticipated revenue, approximates the costs incurred in achieving the
related milestone, as a percentage of the total anticipated costs. Where the contract does not specify milestones and payment is upon completion of the contract, revenue is recognized based on the percentage-of-completion method of accounting. Any
payments received in advance of the completion of a milestone or services performed are recorded as deferred revenue.

Research and
Development Expenditures



Research and
development costs, including development costs of the Companys database product that do not meet the capitalization criteria of Statement of Financial Accounting Standards No. 86 (SFAS No. 86), Accounting for the Cost of Computer
Software to Be Sold, Leased or Otherwise Marketed, are charged to operations as incurred.



Accounting for Stock-Based Compensation



The Company accounts for stock-based employee compensation arrangements in accordance with provisions of Accounting Principles Board Opinion No. 25 (APB 25), Accounting for Stock
Issued to Employees, and related interpretations and complies with the disclosure provisions of Statement of Financial Accounting Standards No. 123 (SFAS 123), Accounting for Stock-Based Compensation.



Under APB 25, compensation expense is based on the difference,
if any, on the date of the grant, between the fair value of the Companys stock and the exercise price. SFAS 123 defines a fair value based method of accounting for an employee stock option or similar equity investment.



The Company accounts for equity instruments
issued to non-employees in accordance with the provisions of SFAS 123 and Emerging Issues Task Force Issue No. 96-18 (EITF 96-18), Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling, Goods or Services, and Financial Accounting Standards Board Interpretation No. 28 (FIN 28), Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans.



During the year ended December 31, 2002, the
Company adopted Statement of Financial Accounting Standards No. 148, Accounting for Stock-Based Compensation, Transition and Disclosure. The following table illustrates the effect on net loss and net loss per common share if the Company
had applied the fair value recognition provisions of SFAS 123 to stock-based employee compensation:

The
above pro forma disclosures are not likely to be representative of the effects on net income (loss) and basic and diluted net income (loss) per share in future years because options vest over several years and additional grants are made each year.

Net Loss Per Share



Basic earnings per share is calculated
based on the weighted average number of common shares outstanding during the period. Diluted earnings per share would give effect to the dilutive effect of common stock equivalents consisting of restricted stock, stock options and warrants.
Potentially dilutive securities have been excluded from the diluted earnings per share calculations as they have an antidilutive effect due to the Companys net losses.



A reconciliation of the numerator and denominator used in the net loss per share calculations is as follows:

Recent Accounting
Pronouncements



In August 2001, the
Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 143 (SFAS 143), Accounting for Asset Retirement Obligations, which is effective for fiscal years beginning after
June 15, 2002. SFAS 143 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. SFAS No. 143 requires, among other things, that the
retirement obligations be recognized when they are incurred and displayed as liabilities on the balance sheet. In addition, the assets retirement costs are to be capitalized as part of the assets carrying amount and subsequently
allocated to expense over the assets useful life. The adoption of SFAS 143 did not have a material effect on the financial position or results of operations of the Company.



In April 2002, the FASB issued Statement of Financial Accounting Standards No. 145 (SFAS 145),
Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections, which is effective for fiscal years beginning after May 15, 2002. Under SFAS 145, gains and losses from the extinguishment of
debt should be classified as extraordinary items only if they meet the criteria of Accounting Principles Board Opinion No. 30. SFAS also addresses financial accounting and reporting for capital leases that are modified in such a way as to give rise
to a new agreement classified as an operating lease. The Company believes that the adoption of SFAS 145 will not have a material effect on the financial position or results of operations of the Company.



In June 2002, the FASB issued Statement of Financial
Accounting Standards No. 146 (SFAS 146), Accounting for Costs Associated with Exit or Disposal Activities, which is effective for exit or disposal activities initiated after December 31, 2002. SFAS 146 nullifies Emerging
Issues Task Force Issue No. 94-3, Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (including Certain Costs Incurred in a Restructuring). Under SFAS 146, a liability is required to
be recognized for a cost associated with an exit or disposal activity when the liability is incurred. SFAS 146 applies to costs associated with an exit activity that does not involve an entity newly acquired in a business combination or with a
retirement or disposal activity covered by FASB Statements No. 143 and 144. The Company elected early adoption of SFAS 146 in the fourth quarter of 2002 in conjunction with the business realignment discussed in Note 18.



In November 2002, the FASB issued FASB Interpretation
No. 45 (FIN 45), Guarantors Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. FIN 45 requires that a liability be recorded in the
guarantors balance sheet upon issuance of a guarantee. In addition, FIN 45 requires disclosures about the guarantees that an entity has issued, including a reconciliation of changes in the entitys product warranty liabilities. The
initial recognition and initial measurement provisions of FIN 45 are applicable on a prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantors fiscal year-end. The disclosure requirements
of FIN 45 are effective for financial statements of interim or annual periods ending after December 15, 2002. The Company believes that the adoption of FIN 45 will not have a material impact on the financial position or results of
operations of the Company.



In November 2002, the
Emerging Issues Task Force (EITF) reached a consensus on Issue No. 00-21 (EITF 00-21), Revenue Arrangements with Multiple Deliverables. EITF 00-21 provides guidance on how to account for
arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets. The provisions of EITF 00-21 will apply to revenue arrangements entered into in fiscal periods beginning after June 15, 2003. The
Company believes that the adoption of EITF 00-21 will not have a material impact on the financial position or results of operations of the Company.

In
December 2002, the FASB issued Statement of Financial Accounting Standards No. 148 (SFAS 148), Accounting for Stock-Based Compensation, Transition and Disclosure. SFAS 148 provides alternative methods of transition for a
voluntary change to the fair value based method of accounting for stock-based employee compensation. SFAS 148 also requires that disclosures of the pro forma effect of using the fair value method of accounting for stock-based employee compensation
be displayed more prominently and in a tabular format. Additionally, SFAS 148 requires disclosure of the pro forma effect in interim financial statements. The transition and annual disclosure requirements of SFAS 148 are effective for fiscal years
ended after December 15, 2002. The interim disclosure requirements are effective for interim periods beginning after December 15, 2002. The adoption of SFAS 148 did not have a material impact on the financial position or results of
operations of the Company.



In January 2003, the
FASB issued FASB Interpretation No. 46 (FIN 46), Consolidation of Variable Interest Entities, an Interpretation of ARB No. 51. FIN 46 requires certain variable interest entities to be consolidated by the primary beneficiary
of the entity if the equity investors in the entity do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial
support from other parties. FIN 46 is effective immediately for all new variable interest entities created or acquired after January 31, 2003. For variable interest entities created or acquired prior to February 1, 2003, the provisions of FIN 46
must be applied for the first interim or annual period beginning after June 15, 2003. The Company is currently evaluating the impact, if any, that the adoption of FIN 46 will have on the financial position or results of operations of the Company.

tax expenses, tenants share of common area and tenants share of utilities. In conjunction with the lease agreement, a standby letter of credit of $150,000 was issued in November 1999 with a financial institution, in favor of the

days in advance.

Legal Matters



On May 24, 2000, Lexicon Genetics Incorporated filed a lawsuit against us in the United States District Court for the District of
Delaware. The complaint in the lawsuit alleged that the Companys methods of making knockout mice infringed United States Patent No. 5,789,215 (the 215 patent), under which Lexicon claimed to be an exclusive licensee. In addition, on
October 13, 2000, Lexicon and the University of Utah Research Foundation filed a lawsuit against us in the United States District Court for the Northern District of California. The complaint in this lawsuit alleged that we infringed United States
Patents Nos. 5,631,153, 5,464,764, 5,627,059 and 5,487,992 (the Capecchi patents), under which Lexicon claimed to be an exclusive licensee. On September 20, 2001, the Company and Lexicon announced the settlement of the litigation. Under the terms of
the settlement, the Company obtained a commercial license under the 215 patent and the Capecchi patents, Lexicon obtained a subscription to the Companys DeltaBase product, and all of the claims and counterclaims in the litigation were
dismissed with prejudice. Lexicons subscription to DeltaBase includes non-exclusive, perpetual licenses to the 250 drug targets represented in DeltaBase as of September 2001 and the approximately 1,000 drug targets that were and are expected
to be added to DeltaBase over the subsequent four years. Lexicon will make certain milestone and royalty payments to the Company for therapeutic and diagnostic products developed from Lexicons use of DeltaBase. The Company will make payments
to Lexicon for knockout mice generated by the Company on a fee-for-service basis. Neither the Company nor Lexicon will pay the other party any subscription or license fees.

Action) and AMB Property, L.P. v. Deltagen, Inc., Case No. 429872 (the AMB Action). The plaintiff in the AMB
Action is the owner of real property located at 1210 and 1255 Hamilton Court, in Menlo Park, California. The plaintiff in the Willow Park Action is the owner of real property located at 1003 Hamilton Court, also in Menlo Park, California. The
Company did not timely pay its rent on the 1003 and 1210 Hamilton Court premises for March 2003, or its rent on the 1255 Hamilton Court premises for February and March 2003.



The complaints allege that the Company breached its leases for the three properties. In the AMB Action, the
plaintiff seeks past due rent and additional rent in the amount of $88,211, late charges in the amount of $8,821, and future rent and additional rent in the amount of $1,773,266. In the Willow Park Action, the plaintiff seeks past due rent and
additional rent in the amount of $75,946, late charges in the amount of $7,594, and future rent and additional rent in the amount of $921,898.



On March 14, 2003, the plaintiffs in both actions applied for an ex parte right to attach order, writ of attachment, and temporary
protective order. The plaintiff sought to attach $1,873,794 in the AMB Action, and $1,168,845 in the Willow Park Action. On March 14, 2003, the court granted the plaintiffs applications in part, and denied them in part. In the AMB Action, the
court ordered that the plaintiff has a right to attach the Companys property in the amount of $97,032. In the Willow Park Action, the court ordered that the plaintiff has a right to attach the Companys property in the amount of $83,541.
The court also issued a temporary protective order in each case, restricting the Company from transferring interests in specified property, and from disposing of the proceeds of any transfer of inventory. The temporary protective orders will expire
no later than April 23, 2003. The Company executed a Lease Termination Agreement with the plaintiffs effective March 31, 2003. Under this agreement the plaintiffs agreed to dismiss these actions promptly after June 30, 2003 except under certain
circumstances as defined in the agreement.



The
Company may be involved in additional litigation, investigations or proceedings in the future. Any litigation, investigation or proceedings, with or without merit, could be costly and time-consuming and could divert the Companys
managements attention and resources, which in turn could harm the Companys business, financial position, and financial results and cash flows.

6.    ACQUISITIONS



Acquisition of Arcaris, Inc.



On July 30, 2001, the Company acquired Arcaris, Inc.
(Arcaris). Located in Salt Lake City, Utah, Arcaris has developed technologies consisting of genetic, proteomic and cell-biological systems for identification and validation of drug targets and the creation of small molecule screens. The
total purchase price of approximately $8,043,000 consisted of cash of approximately $450,000 and 766,894 shares of common stock valued at approximately $6,751,000 and 77,329 vested stock options valued at approximately $418,000, direct acquisition
costs of approximately $312,000 and 94,095 shares of common stock valued at $112,000 and issued in October 2002 related to certain earn out provisions. The acquisition was accounted for using the purchase method of accounting. The Arcaris
acquisition added a new technology platform to the Companys existing high-throughput efforts to identify and validate small molecule targets relevant to small molecule drug screening. The information generated through the Arcaris technologies
was intended to be utilized to advance the discovery of a new disease targets by defining the role of novel non-traditional targets within intracellular pathways with particular relevance to oncology, viral and infections diseases. Additionally, the
Arcaris technologies were intended to be used to facilitate the rapid development of small molecule screens against these identified targets.



The total purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed based on independent
appraisals and management estimates as follows (in thousands):



|Tangible net assets acquired:                     |  |   |        |

In
connection with the purchase of Arcaris, the Company recorded a $907,000 charge to in-process research and development. The amount was determined by identifying research projects for which technological feasibility had not been established and no
alternative future uses existed. The value of the projects identified to be in progress was determined by estimating the cost to recreate the technology and the future cash flows from the projects once commercially feasible, discounting the net cash
flows back to their present value and then applying a percentage of completion to the calculated value. The net cash flows from the identified projects are expected to commence at various times in 2002, and were based on estimates of revenues, cost
of revenues, research and development costs, selling, general and administrative costs and applicable income taxes for the projects. The percentage of completion for the projects was determined based on man months expended to date as a percentage of
total project man months for the project. The discount rates used in the present value

calculations were typically derived from a weighted-average cost of capital analysis based upon comparable public companies, adjusted upward
to reflect additional risks inherent in the development life cycle. Such discount rates ranged between 22% and 27% for all projects. Development of the technologies remains a substantial risk to the Company due to factors including the remaining
effort to achieve technological feasibility, rapidly changing customer markets and competitive threats from other companies.



The amount allocated to completed technology is being amortized over their estimated useful life of three years using the straight-line
method. This completed technology was written-off as part of the charge for impairment of intangible assets during 2002 as discussed in Note 10.



The amount of the purchase price in excess of the net assets acquired was recorded as goodwill. This goodwill was written-off as a part of
the charge for goodwill impairment during 2002 as discussed in Note 10.



In October 2002, the Company issued 94,095 additional common shares in final settlement of contingent purchase consideration related to the acquisition of Arcaris, Inc.



On October 2, 2002, the Company announced a cost savings and
business restructuring plan to reduce its cash burn rate. The plan included the consolidation of core activities into the Companys Redwood City, California and Salt Lake City, Utah facilities as discussed in Note 18.



Acquisition of BMSPRL, L.L.C.



On February 16, 2002, the Company completed the acquisition
of BMSPRL, L.L.C. (BMSPRL), formerly known as CombiChem, Inc., from Bristol-Myers Squibb Company for 2,647,481 unregistered shares of the Companys common stock valued at approximately $23,510,000 and incurred acquisition related
costs of approximately $465,000. The subsidiary, located in San Diego, California, was renamed Deltagen Research Laboratories, or DRL. The addition of DRL was intended to enable the Company to advance its targets by identifying lead candidate
compounds for drug development.



Accordingly, the
results of operations of BMSPRL and estimated fair value of assets acquired and liabilities assumed were included in the Companys consolidated financial statements from February 16, 2002 through December 31, 2002.

part of the charge for intangible asset impairment during 2002 as discussed in Note 10.



The amount of the purchase price in excess of the net assets acquired was recorded as goodwill. This goodwill was written-off as part of the charge for goodwill impairment during 2002 as discussed in
Note 10.



On October 2, 2002, the Company
announced a cost savings and business restructuring plan to reduce cash burn rate. The plan includes the closing of the San Diego facility that housed the DRL operations. As a result of the restructuring plan, substantially all DRL activities and
chemistry capabilities have ceased or been eliminated as discussed in Note 18.



Acquisition of XenoPharm, Inc.



On March 14, 2002, the Company acquired XenoPharm, Inc. (XenoPharm), a San Diego, California-based private company for 498,236 unregistered shares of the Companys common stock valued at approximately $3,622,000 and
incurred acquisition related cost of approximately $536,000. Additionally, the Company may be required to issue up to an additional 1,449,262 shares of common stock upon the satisfaction of certain milestones. XenoPharm provides a proprietary
technology platform to pharmaceutical, biotechnology, chemical and agricultural companies to better understand and predict reactions of foreign substances, termed xenobiotics, in human systems. XenoPharms XenoSensor Mice, implanted
with human SXR and CAR, coupled with XenoPharms CleanScreen high-throughput screening assays provide a proprietary technology platform to improve the predictive value of cell- and animal-based biomedical research.



The results of operations of XenoPharm and estimated fair
value of assets acquired and liabilities assumed were included in the Companys consolidated financial statements from March 14, 2002 through December 31, 2002.



The total purchase price was allocated to the estimated fair value of assets acquired and liabilities assumed
based on independent appraisals and management estimates as follows (in thousands):



|Tangible net assets acquired:                |  |   |        |

In
connection with the purchase of XenoPharm, the Company recorded a $110,000 charge to in-process research and development in the March 31, 2002 quarter. The amount was determined by identifying research projects for which technological feasibility
had not been established and no alternative future uses existed. The value of the projects identified to be in progress was determined by estimating the future cash flows from the

projects once commercially feasible, discounting the net cash flows back to their present value and then applying a percentage of completion
to the calculated value. The net cash flows from the identified projects were expected to commence at various times in 2002, and were based on estimates of revenues, cost of revenues, research and development costs, selling, general and
administrative costs and applicable income taxes for the projects. The discount rates used in the present value calculations were typically derived from a weighted-average cost of capital analysis based upon comparable public companies, adjusted
upward to reflect additional risks inherent in the development life cycle. Such discount rates ranged between 45% and 55% for all projects. Development of the technologies remains a substantial risk to the Company due to factors including the
remaining effort to achieve technological feasibility, rapidly changing customer markets and competitive threats from other companies.



The amount allocated to completed technology is being amortized over the estimated useful life of three years using the straight-line
method.



The amount of the net assets in excess
of the purchase price was recorded as a deferred credit since the Company may be required to issue additional shares of common stock upon the satisfaction of certain milestones. The amount of additional consideration paid will reduce the deferred
credit and be included as additional purchase price. If the milestones are not met or the value of the common stock issued is less than the deferred credit, the excess will primarily reduce the value of the completed technology.

8.    LOANS PAYABLE



In December 1998, the Company entered into a loan agreement with a financial institution to obtain one or more loans totaling up to $1,800,000. A corresponding amount of machinery, equipment and other property is pledged as
collateral for each loan. In January 1999 and March 1999, the Company incurred loans of $872,000 and $928,000, respectively, for a total financing of $1,800,000. These loans bear respective interest rates of 10.87% and 11.11% and are required to be
repaid in 48 monthly installments, beginning in January 1999 and April 1999, respectively. At December 31, 2002, there is no amount available for future borrowings and $47,000 was outstanding under this agreement.



In accordance with this loan agreement, the financial
institution received a warrant to purchase 23,510 shares of the Companys Series B preferred stock at a price of $1.53 per share. The warrant term is seven years and expires in January 2006. The value of the warrant was calculated using
the Black-Scholes pricing model and has been charged to additional paid-in capital and is being amortized to interest expense over the life of the loan. The assumptions used in the Black-Scholes model are as follows: dividend yield of 0%, term of
seven years, expected volatility of 75% and risk-free interest rate of 4.96%. In September 2000, the warrant was exercised.



The Company recorded a loan discount related to these warrants of $99,000, of which $29,000, $23,000 and $26,000 have been amortized to
interest expense during the years ended December 31, 2002, 2001 and 2000, respectively.

11.89% and are required to be repaid in 48 monthly installments, beginning in July 1999 and November 1999, respectively. At December 31, 2002, there is no amount available for future borrowings and no amount was outstanding under this agreement.



In March 1999, in conjunction with this loan
agreement, the Company issued a warrant to purchase 19,591 shares of Series B preferred stock at a price of $1.53 per share. The warrant has a seven-year term and expires in March 2006. The value of the warrant was calculated using the
Black-Scholes pricing model and has been charged to additional paid-in capital and is being amortized to interest expense over the life of the loan. The assumptions used in the Black-Scholes model are as follows: dividend yield of 0%, term of seven
years, volatility of 75% and risk-free interest rate of 5.23%. In September 2000, the warrant was exercised.

The
Company recorded a loan discount related to these warrants of $86,000, of which $26,000, $22,000 and $22,000 have been amortized to interest expense during the years ended December 31, 2002, 2001 and 2000, respectively.



In June 2000, the Company entered into a loan agreement with a
financial institution to obtain one or more loans totaling up to $6,500,000. A corresponding amount of machinery, equipment and other property is pledged as collateral for each loan. During June 2000, the Company incurred loans of $1,262,000 and
$1,649,000 for a total financing of $2,911,000. These loans bear respective interest rates of 12.75% and 12.49% and are required to be repaid in 36 and 48 monthly installments, respectively, beginning in July 2000. At December 31, 2002, there is no
amount available for future borrowings and $876,000 was outstanding under this agreement.



During June 2001, the Company entered into a loan with a financial institution in the amount of $2,453,000. This loan bears interest at 12.49% and is required to be repaid in 48 monthly installments
beginning in July 2001. A corresponding amount of machinery, equipment and other property is pledged as collateral for this loan. At December 31, 2002, there was $1,608,000 outstanding under this agreement.



On February 28, 2002, the Company entered into a loan
agreement with a financial institution to obtain one or more loans totaling up to $4,000,000. A corresponding amount of machinery, equipment, and other property is pledged as collateral for each loan. On March 1, 2002, the Company received loan
proceeds of $2,406,000 and $1,000,000, respectively, under this agreement for a total financing of $3,406,000. The loans bear interest rates of 8.87% and 8.98%, respectively, and are to be repaid in 36 monthly installments beginning in March 2002.
On June 21, 2002, the Company received loan proceeds of $593,000 under this agreement. The loan bears interest at 9.04% and is to be repaid in 36 monthly installments beginning in June 2002. At December 31, 2002, there is no amount available for
future borrowings and $3,005,000 was outstanding under this agreement.



The loan agreements have restrictive covenants requiring minimum unrestricted cash balances of twelve month cash needs. If unrestricted cash balances fall below the minimum levels, the Company will be required to
provide cash deposits of up to $2,316,000. In October 2002, the Company provided letters of credit for $2,316,000 to the lender as additional collateral for these and other equipment loans. The letters of credit required $2,316,000 of cash to be
restricted at December 31, 2002. In April 2003, the Company restructured the loan agreement resulting in the restricted cash being applied to the outstanding debt balance.



On June 27, 2002, the Company entered into two new bank agreements. These include a $20,000,000 term loan
facility and a one year $5,000,000 accounts receivable facility. The term loan can be drawn down through March 31, 2003 and matures through March 31, 2007. The loan is collateralized by a first position security interest in substantially all of the
Companys assets excluding intellectual property. The Company has certain restrictions on the assignment or transfer of intellectual property during the term of the loan. The Company borrowed $10,000,000 under this facility on June 28, 2002 at
a variable interest rate of 6.125%. Interest-only payments will be made through the end of the draw-down period at which time outstanding principal and interest will be due in 48 equal monthly installments. The loan has financial covenants related
to earnings and liquidity, including a requirement that the Company maintain unrestricted cash balances, as defined, equal to the greater of two times the principal balance outstanding on the loan or six months of net cash used in operating
activities. On October 31, 2002, the Companys unrestricted cash balances were below the minimum level and the Company provided restricted cash of $10,500,000 as collateral for the term loan facility and the interest rate on the $10,000,000
borrowing was reduced to the prime rate (currently 4.25%). At December 31, 2002, there is no amount available for future borrowings and $10,000,000 was outstanding under this agreement. On March 6, 2003 the Company repaid the loan in full without
penalty and the remaining restricted cash was released.

Amortization expense was $3,787,000 and $561,000 for the years ended December 31, 2002 and 2001 respectively.



10.    IMPAIRMENT OF GOODWILL, INTANGIBLE ASSETS AND OTHER LONG-LIVED ASSETS



Due to current operating losses, the absence of positive cash
flows, recent significant declines in the Companys common stock price and uncertainties resulting from the business restructuring plan, the Company assessed the recoverability of its intangible assets and long-lived assets related to DRL and
Arcaris in accordance with SFAS 144 and tested goodwill for impairment in accordance with SFAS 142 during the year ended December 31, 2002. Based upon our projection of significantly reduced future cash flows related to the intangible assets and
long-lived assets, an impairment loss of $7,103,000 was recognized for completed technology and $12,418,000 for property and equipment in the year ended December 31, 2002. The carrying value of the long-lived assets has been written down to expected
fair value. The impairment test under SFAS 142 was based on a two-step process involving: (i) comparing the estimated fair value of the related reporting unit to its net book value and (ii) comparing the estimated implied fair value of goodwill to
its carrying value. As a result of the test, we wrote down goodwill by $9,372,000 in the year ended December 31, 2002.



11.    PROPERTY PLANT AND EQUIPMENT FINANCING



In August 2001, the Companys wholly-owned Deltagen Europe S.A. subsidiary entered into a lease purchase
arrangement associated with the construction of a research and development facility in France. Under the terms of the arrangement, the Company paid $1,520,000 for the purchase of land and paid approximately $718,000 in security deposits in
conjunction with a ten-year financing arrangement that provides approximately $6,200,000 in funds for construction of a 50,000 square-foot research and development building. The land and security deposits are collateral for the loan. The loans were
provided by a consortium of banks and local governmental agencies. The loans bear interest at the average monthly money market rates plus 1.5% during construction. Once construction is completed, approximately $2,700,000 of the loan bears interest
at the three- month Euro Interbank Offered Rate, plus 1.5% and approximately $3,500,000 bears interest at 1.5%. Construction of this facility has not begun and in October 2002 the Company cancelled the construction project and the committed
financing was withdrawn. The security deposit will be retained by the lenders as a recovery of costs incurred prior to cancellation of the project.



12.    NOTES RECEIVABLE FROM RELATED PARTIES



In April 2001, the Company received promissory notes from certain officers for $150,000 and $110,000,
respectively. The promissory notes are collateralized by 58,824 and 43,137 shares of common stock, bear annual interest at 4.94% and are payable in April 2006 or earlier upon employee termination. In February 2003, a certain officer resigned and the
related note for $150,000 became due.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)





In March
2001, the Company received a promissory note from an employee for $60,000. The promissory note bears annual interest at 4.75% and is payable in March 2003 or earlier upon employee termination.



In March and May 2000, the Company received promissory notes
from two officers for $50,000 each. The promissory notes are collateralized by real estate and accrue interest at 6.80% and 6.08%, respectively. The principal amount of the notes and all accrued and unpaid interest are due and payable in May 2004.



In July 2000, the Company received a promissory
note from an employee for $75,000. The promissory note is collateralized by real estate, bears annual interest at 6.62% and is payable in July 2004. The promissory note and accrued interest was paid in full in August 2002.



In June 2002, the Company received a promissory note from an
officer for $630,000. The promissory note is collateralized by real estate, bears interest at 5.0% per annum and is due and payable in June 2007 or earlier upon the termination of employment. On December 18, 2002, the officers employment with
the Company terminated and the outstanding balance of the note, including accrued interest, was forgiven.



13.    REDEEMABLE CONVERTIBLE PREFERRED STOCK



In February and May 1997, the Company issued 3,428,571 shares of Series A redeemable convertible preferred stock at $0.88 per share for
net proceeds of $2,980,000. In February and July 1998, the Company issued 7,510,206 shares of Series B redeemable convertible preferred stock at $1.53 per share for net proceeds of $11,467,000. In January 2000, the Company issued 7,198,709 shares of
Series C redeemable convertible preferred stock at $3.13 per share for net proceeds of $22,360,000. The difference between the conversion price of the Series C redeemable convertible preferred stock and the fair market value of the common stock on
the transaction date resulted in a beneficial conversion feature of approximately $22,360,000, which has been reflected as a preferred stock dividend in the December 31, 2000, financial statements.



Upon the closing of the Companys initial public
offering, all of the Companys outstanding redeemable convertible preferred stock converted into 18,137,486 shares of common stock.



14.    STOCKHOLDERS EQUITY



Stock Split



In July 2000, the Company effected an 8-for-7 forward split of its preferred and common stock. All common stock data and common stock
option plan information in these financial statements has been restated to reflect the split.



Common Stock



At December 31, 2002, the Company had reserved sufficient shares of common stock for issuance upon the exercise of stock options and warrants. Common stockholders are entitled to dividends as and when declared by the board
of directors subject to prior rights of the preferred stockholders. The holders of each share of common stock are entitled to one vote.



In August 2000, the Company completed its initial public offering of 8,025,000 shares of common stock, including 1,025,000 shares in
connection with the exercise of the underwriters over over-allotment option, at a price of $15.00 per share, that raised approximately $110,191,000, net of underwriting discounts, commissions and other offering costs. Upon the closing of the
offering, all of the Companys redeemable convertible preferred stock converted into 18,137,486 shares of common stock.

Common
stock held by certain employees and non-employees is subject to stock purchase agreements whereby the Company has the option to repurchase unvested shares upon termination of employment at the initial issuance price. The Companys right to
repurchase these shares generally lapses at the rate of 25% per year from the date of the agreement. At December 31, 2002 and 2001, 265,000 and 649,450 shares of common stock remain subject to the Companys right of repurchase, respectively.



Private Placement



In May 2002, the Company completed a private equity financing
in which 5,543,822 shares of common stock were sold at $4.57 per share resulting in net proceeds of approximately $25,123,000.



2000 Employee Stock Purchase Plan



In April 2000, the board of directors adopted the 2000 Employee Stock Purchase Plan (the 2000 ESPP). Under the 2000 ESPP,
1,142,857 shares of common stock have been reserved for issuance, subject to increase on the first day of each fiscal year. The 2000 ESPP contains overlapping 24-month offering periods and successive 6-month accumulation periods. The price of stock
purchased under the ESPP shall be the lower of 85% of the fair market value of such shares on the last trading day in such accumulation period or 85% of the fair market value of such shares on the last trading day before the commencement of the
applicable offering period. During 2002 and 2001, 96,184 and 30,792 shares, respectively, were purchased under the 2000 ESPP.



Stock Option Plans



In April 1998, the Company adopted the 1998 Stock Incentive Plan (the 1998 Plan). The 1998 Plan provides for the granting of
stock options and restricted shares to employees and consultants of the Company. Options granted under the 1998 Plan may be either incentive stock options or nonqualified stock options. Incentive stock options (ISOs) may be granted only
to Company employees (including officers and directors who are also employees). Nonqualified stock options (NSOs) may be granted to Company employees and consultants. At December 31, 2002, the Company has reserved 4,293,462 shares of
common stock for issuance under the 1998 Plan.



Options under the Plan may be granted for periods of up to ten years or five years in the case of a 10% stockholder and at prices no less than 85% of the fair market value of a share on the date of grant, provided, however, that the
exercise price of an ISO and NSO may not be less than 100% and 85% of the fair market value of a share on the date of grant, respectively, and the exercise price of an ISO and NSO granted to a 10% shareholder may not be less than 110% of the fair
market value of a share on the date of grant, respectively. To date, options granted generally vest over four years.



In April 2001, the Company adopted the 2000 Stock Incentive Plan (the 2000 Plan). The 2000 Plan provides for the granting of
incentive stock options only to employees and non-statutory stock options, restricted shares, stock units or stock appreciation rights (SARs) to employees, non-employee directors and consultants.



Under the 2000 Plan, at December 31, 2002 9,120,714 shares of
common stock have been authorized for issuance that will terminate no later than 2011. On January 1 of each year the number of shares reserved for issuance may be increased, but limited to a total of 45,714,286 authorized shares.



Certain stock options granted are subject to acceleration of
vesting in the event of a change in control of the Company. The purchase price for restricted shares and the exercise price for stock options and SARs will be

determined by the Committee in charge of the 2000 Plan administration. The exercise price of an ISO may not be less than 100% of the fair
market value of a share on the date of grant and the term may not exceed ten years or five years in the case of a 10% stockholder.



In connection with the acquisition of Arcaris, Inc., in July 2001, the Company assumed the Arcaris, Inc. 1997 Equity Incentive Plan (the
1997 Plan). The 1997 Plan provides for the granting of stock options, stock bonuses and restricted stock to employees, directors and consultants of the Company. Under the 1997 Plan, ISOs may be granted only to Company employees
(including officers and directors who are also employees) and NSOs may be granted to Company employees and consultants.



Options under the 1997 Plan may be granted for periods of up to ten years or five years in the case of a 10% stockholder and at prices no
less than 85% of the fair market value of a share on the date of grant provided, however, that the exercise price of an ISO and NSO may not be less than 100% and 85% of the fair market value of a share on the date of grant, respectively, and the
exercise price of an ISO and NSO granted to a 10% stockholder may not be less than 110% of the fair market value of a share on the date of grant, respectively.

At
December 31, 2001 and 2000, outstanding options to purchase 1,696,000 shares and 503,000 shares of common stock were exercisable and vested at a weighted average exercise price of $6.01 and $0.85 per share, respectively.



The fair value of each option grant is estimated on the date
of grant using the Black-Scholes option pricing method with the following weighted average assumptions:



|                         |  | Years Ended December 31, |  
|------------------------ |  | ------------------------ | -
|                         |  | 2002                     |  
|Risk-free interest rate  |  | 4.84                     | %
|Expected life (in years) |  | 5                        |  
|Expected dividends       |  |                         |  
|Volatility               |  | 113.9                    | %



The
expected life is based on the assumption that stock options on average are exercised one year after they are fully vested. The risk-free interest rate was calculated in accordance with the grant date and the life term of the options.



Based on the above assumptions, the weighted average fair
values per share of options granted under the 1998 Plan and 2000 Plan were $4.74, $6.14 and $10.54 for the years ended December 31, 2002, 2001 and 2000, respectively.



The fair value of each 2000 ESPP share is estimated on the date of issuance using the Black-Scholes option
pricing model with the following weighted average assumptions:



|                         |  | 2002  |   |  | 2001 |  
|------------------------ |  | ----- | - |  | ---- | -
|Expected dividend yield  |  | 0.0   | % |  | 0.0  | %
|Risk-free interest rate  |  | 4.77  | % |  | 4.22 | %
|Expected volatility      |  | 113.9 | % |  | 95.3 | %
|Expected life (in years) |  | 0.5   |   |  | 0.5  |  



The
weighted average grant date fair value of the 2000 ESPP shares issued during 2002 and 2001 was $1.66 and $2.95 per share, respectively.

Unearned Stock-based
Compensation



During 2000 and 1999, the
Company issued stock options and restricted shares to certain employees with exercise prices below the deemed fair value of the Companys common stock at the date of grant. In accordance with the requirements of APB 25, the Company has recorded
unearned stock-based compensation for the difference between the exercise price of the stock options and the deemed fair value of the Companys common stock at the date of grant. This unearned stock-based compensation is amortized to expense
over the period during which the options vest, generally four years, using the method set out in FIN 28. Under the FIN 28 method, each vested tranche of options is accounted for as a separate option grant awarded for past services. Accordingly, the
compensation expense is recognized over the period during which the services have been provided. The Company has recorded unearned stock-based compensation for options and restricted shares granted to employees of $10,415,000 and $10,178,000 for the
years ended December 31, 2000 and 1999, of which $1,580,000, $4,056,000, and $9,786,000 have been amortized to expenses during fiscal years 2002, 2001 and 2000.



For stock options and restricted stock granted to non-employees, generally for future services, the fair
value of the options, measured using the Black-Scholes option pricing model, is initially recorded as unearned stock-based compensation on the date of grant. As the non-employee fulfills the terms of the option grants relating to continued service
to the Company, the Company revalues the remaining unvested options, with the change in fair value from period to period represented as additional unearned stockbased compensation. As a result, the stock- based compensation expense will
fluctuate as the fair market value of the Companys common stock fluctuates. The unearned stock-based compensation is amortized to expense over the period during which services are performed, generally four years, using the method set out in
FIN 28. Amortization of unearned stock-based compensation for options granted to non-employees was $1,086,000 for the year ended December 31, 2000. During the years ended December 31, 2002 and 2001, the Company reversed $191,000 and $152,000 of
previously recognized unearned stock-based compensation related to unvested stock options due to changes in the fair market value of the Companys common stock.



Notes Receivable From Stockholders



In March 2000, the Company issued 514,286 shares of common stock to two officers in exchange for full
recourse promissory notes of $805,000. The promissory notes are collateralized by the common stock and accrue interest at 6.8% per annum. The principal and all accrued and unpaid interest are due and payable in March 2004, or upon the termination of
employment.



Warrants



In September 2000, the Company issued a warrant to purchase
15,000 shares of common stock at $16.88 per share to a non-employee. The warrant is fully vested and exercisable for three years from the date of issuance. The fair value of the warrant of approximately $265,000 was expensed in the year ended
December 31, 2000.



The fair value of the warrant
calculated on the date of issuance was determined using the Black-Scholes option pricing model with the following assumptions: dividend yield of 0%; expected term of the warrant of three years; risk-free interest rate of 5.86% and volatility of 75%.



15.    EMPLOYEE BENEFIT PLAN



In 1999, the Company established a 401(k)
Plan to provide tax-deferred salary deductions for all eligible employees. Participants may make voluntary contributions to the Plan of up to 20% of their compensation, limited by certain Internal Revenue Service restrictions. The Companys
matching contribution is discretionary as determined by the board of directors. The Company has not contributed to the plan since its inception.

complement the Companys production and licensing of its DeltaBase product. The Company also expects to continue to pursue its internal
drug discovery and development in secreted proteins through its current and potential future collaborations.



As part of this restructuring, the Company reduced its staff by approximately 130 employees. The plan included the closing of its San
Diego operations acquired in the acquisition of BMSPRL, L.L.C., as discussed in Note 6, the planned exit from its operations in Europe and the planned consolidation of core activities into the Companys Redwood City, CA and Salt Lake City, UT
facilities.



As a result of these actions, the
Company recorded a charge in 2002 for the impairment of intangible assets related to activities that will no longer be pursued or that will be scaled back and for the impairment of fixed assets including leasehold improvements and equipment (Note
10). The Company also recorded a charge in 2002 for severance and other employee related costs, costs associated with lease obligations and other costs. These costs relate primarily to the Companys operations in San Diego, California (BMSPRL,
L.L.C. acquisition), Salt Lake City, Utah (Arcaris, Inc. acquisition in 2001) and Europe.



The following table sets forth certain details associated with the business restructuring charges (in thousands of dollars):

21.    SUBSEQUENT EVENTS



(a)    Business Restructuring



On January 6, 2003, the Company announced a restructuring of its business and a cost reduction plan. The Companys business strategy will focus on providing drug discovery tools and services to the biopharmaceutical
industry utilizing the Companys proprietary in vivo mammalian transgenic technologies. The Company has decided to terminate its internal small molecule drug discovery and development programs.



As part of this restructuring, the Company reduced its staff
to approximately 200 employees. The plan included the closing of its Strasbourg, France operations and its Salt Lake City operations acquired in the acquisition of Arcaris, Inc., as discussed in Note 6, and the planned consolidation of core
activities into the Companys Redwood City, California facility.



The Company will record a charge in the first quarter of 2003 for severance and other employee related costs, costs associated with lease obligations and other costs. These costs relate primarily to the Companys
operations in Strasbourg, France, Salt Lake City, Utah (Arcaris acquisition in 2001) and excess facilities in Alameda and Menlo Park, California.



In April 2003, the Company announced a further 50 employee reduction in staff to approximately 150 employees. The Company will record
a charge in the second quarter of 2003 for severance and other employee related costs.



(b)    Notes Receivable from Related Parties



In January 2003, an amount equal to $41,000, including accrued interest, of the outstanding balance of a promissory note for $50,000 from
an officer was forgiven. The remaining balance of the note and the remaining accrued interest was paid in full.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)





In January
2003, an amount equal to $43,000, including accrued interest, of the outstanding balance of a promissory note for $50,000 from an officer was forgiven. The remaining balance of the note and accrued the remaining interest was paid in full.



(c)    Notes Receivable from Stockholders



In January 2003, a promissory note from an
officer in the amount of $537,000 was settled in exchange for cash, the cancellation of options and the repurchase of stock.



In February 2003, a promissory note from an officer in the amount of $268,000 was settled in exchange for cash, the cancellation of
options and the repurchase of stock.



(d)    License Agreement



In February 2003, the Company granted a royalty-free, fully paid, worldwide, non-exclusive, non-transferable, non-sublicenseable, internal license to Bristol-Meyers Squibb Company for certain patent rights in exchange for
1,800,000 shares of Deltagen, Inc. common stock.



(e)    Loans Payable



In March 2003, the Company repaid in full, without penalty, the outstanding balance of $10,000,000 under its term loan facility. As a result of this payment, the Company is no longer required to maintain restricted cash balances of
$10,500,000 as security for the loan facility.



In March 2003, the Company reached an agreement with a financial institution to restructure its existing loan agreements. The existing loan agreements had outstanding balances at March 15, 2002 of $5,048,000 and were payable in
monthly installments at interest rates ranging from 8.87% to 12.75% with maturities to July 2005. Under the terms of the restructuring, the Company forfeited letters of credit totaling $2,316,000 to the lender in partial payment of the loans and
entered into a new loan for the remaining balance of $2,732,000. The new loan will bear an interest rate of 10.50% and is required to be repaid in 18 monthly installments, beginning in April 2003. The loan is collateralized by a first position
security interest in certain fixed assets and a second position security interest in substantially all of the Companys other assets.



Future principal payments of loans payable are as follows (in thousands):



|                         |  | Amount
|------------------------ |  | ------
|Year Ending December 31, |  |

|                         |  |       



(f)    Facility Leases



In March and April 2003 the Company entered into agreements with landlords or guarantors of several excess facilities in San Diego, CA; Menlo Park, CA; Alameda, CA; and Redwood City, CA to terminate remaining lease
obligations. Certain of the terminations are contingent on the Company closing the Series A Preferred Stock financing described below. These agreements require the Company to forfeit lease deposits or restricted cash underlying letters of credit
totaling $2,534,000 in 2003, make lease termination payments totaling $2,290,000 in 2003 and $200,000 in 2004 and issue warrants to purchase 1,150,000 shares of the Companys Series A Preferred Stock plus additional warrants equal to 0.05
warrants per dollar for each dollar of Series A preferred stock issued in excess of $10 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)





In
addition, in April 2003 the Company entered into a forbearance agreement related to the lease of its principal operating and administrative facility in Redwood City, CA. This agreement provides for lease rent and certain facility operating expense
to be paid from the Companys $1.5 million cash security deposit or $500,000 restricted cash related to letters of credit in 2003. Lease rent is also reduced by approximately 25% during the forbearance period. The agreement has certain default
criteria that if breeched would cause the lease rent to revert to prior levels retroactively.



(g)    Bridge Loan and Commitment for Equity Financing



In April 2003, the Company obtained a minimum commitment for $10 million in equity capital from existing institutional investors to
purchase Series A Preferred Stock in a transaction referred to here in as a private placement. The private placement is subject to shareholder approval and the satisfaction of closing conditions. In addition to the terms of the private placement,
Deltagens stockholders will be asked to approve a number of other matters including a reverse stock split.



Under the terms of the private placement, the investors have agreed to purchase $10 million of Series A Preferred Stock. The preferred
stock is convertible into common stock on a 1:1 basis. The preferred stock will be issued at a 25% discount to the five-day average closing common stock price for the period ending three days prior to closing. The preferred stock bears no dividend,
has a liquidation preference right equal to the amount invested in the preferred stock and standard anti-dilution protections. The terms of the preferred stock agreement include the right to appoint designees to a total of three seats on the
Companys Board of Directors.



The Company
also obtained a secured bridge loan commitment from the same investors of $5 million. This facility can be increased to $6 million upon the occurrence of certain events and milestones and is collateralized by all of the Companys assets not
pledged to the equipment loans. The loan bears interest at 10% per annum. The principal and interest on the bridge loan will be repaid upon the earlier of the closing of the private placement with a portion of the proceeds thereof or August 31,
2003.



In connection with the private placement,
the Company has agreed to use reasonable best efforts, as soon as reasonably practicable after the closing of the private placement, to offer stockholders of record as of the last business day prior to the closing of the private placement (other
than the investors in such financing) non-transferable rights to purchase newly issued preferred stock at the same purchase price paid by the investors. The amount of preferred shares so offered to each stockholder would be sufficient to allow each
such stockholder to maintain the percentage ownership interest in the Company held by each such stockholder as of the last business day prior to the closing of the private placement.



(h)    Legal Matters



On April 28, 2003, the Company received from Lexicon a letter which Lexicon claims serves as notice of
termination of the sublicense agreement under which the Company obtained a commercial license to the 215 patent and the Capecchi patents. In this letter, Lexicon specified two grounds that allegedly entitles Lexicon to terminate the
sublicense agreement: (1) the Companys purported material breach of the DeltaBase agreement, under which Lexicon obtained a commercial license to our DeltaBase product; and (2) the Companys purported insolvency. On April 29, 2003, the
Company received from Lexicon a letter which Lexicon claims serves as notice under the DeltaBase agreement of: (1) Lexicons alleged entitlement to damages in the amount of $25 million, plus attorneys fees and costs, for the
Companys purported material breach of the DeltaBase agreement; and (2) alleged noncompliance with the content criteria in the DeltaBase agreement. The Company believes that Lexicons claims and allegations are without merit, and intends
to promptly address these claims according to the dispute resolution procedures provided by the settlement and other agreements between Lexicon and Deltagen.

attached as Appendix A to our Proxy Statement for our 2001 Annual Meeting. The Board does not have a nominating committee or a committee performing the functions of a nominating committee.



Section 16(a) Beneficial Ownership Reporting Compliance



Under U.S. securities laws, directors, certain executive officers and persons holding more than 10% of our Common Stock must report their initial ownership of the Common Stock and any changes in that
ownership to the Securities and Exchange Commission. The Securities and Exchange Commission has designated specific due dates for these reports, and we must identify in this Proxy Statement those persons who did not file these reports when due.
Based solely on our review of copies of the reports filed with the Securities and Exchange Commission and written representations of our directors and executive officers, we believe all persons subject to reporting filed the required reports on time
in fiscal year 2002.

|(1) |  | The value of unexercised in-the-money options held at December 31, 2002 represents the total gain which an option holder would realize if he exercised all of the
in-the-money options held at December 31, 2002, and is determined by multiplying the number of shares of Common Stock underlying the options by the difference between the closing stock price of $0.48 per share on the last day of trading in 2002 and
the per share option exercise price. An option is in-the-money if the fair market value of the underlying shares exceeds the exercise of the option.

price of $4.45 and a stock option grant of 60,000 shares with an exercise price of $4.45 vesting monthly from June 2002 through May 2006. Mr. Penhoet resigned from the Board in January 2003. In December 2002, Dr. Anagnostopoulos received a stock
option grant of 90,000 shares with an exercise price of $0.60 vested immediately. These options will vest monthly over a three-year period. In December 2002 Dr. Anagnostopoulos entered into a consulting agreement with Deltagen. Pursuant to the
agreement Dr. Anagnostopoulos is to receive $3,000 per day for each day that he provides consulting services to Deltagen from the period beginning November 14, 2002. He is not to receive such amount for days in which he provides services solely in
his capacity as a non-employee Director of Deltagen. During 2002, Dr. Anagnostopoulos earned $39,000 pursuant to this agreement. The agreement also provides for a non-statutory option grant of 30,000 shares each month beginning March 3, 2003.
The payments and share grants under this agreement will cease on April 16, 2003. Directors who are Deltagen employees receive no compensation for their services as directors.



EMPLOYMENT AGREEMENTS



On April 2, 2003, we entered into an employment agreement with Joseph M. Limber as our Interim Chief Executive Officer (ICEO). Mr. Limber had provided consulting services to Deltagen in early 2003 prior to his hire.
Pursuant to this employment agreement, upon the closing of the Private Placement, Mr. Limber will become our President and Chief Executive Officer and he will be appointed to Board of Directors.



The employment agreement provides that Mr. Limber will serve
full-time in an at-will capacity as our ICEO and that he will earn an annual base salary of $365,000 which shall be subject to review on an annual basis. Mr. Limber will be eligible to earn an annual cash bonus based upon accomplishment of
specified performance objectives with a target bonus amount of 50% of his base salary. The actual amount of any bonus awarded, if any, shall be determined by the Board of Directors and may be more or less than the target amount. Under the agreement,
in April 2003 Mr. Limber was awarded a stock option to purchase up to 1,714,285 shares of our Common Stock at a per-share price equal to the fair market value of a share of our Common Stock on the date of grant. 43,731 shares subject to the option
were vested at grant and the remaining option shares will vest pro-rata on a monthly basis over four years subject to Mr. Limbers continued service to Deltagen. The employment agreement also provides that Mr. Limber will receive a second stock
option grant so that his aggregate equity stake in Deltagen will be equal to 5% of our fully-diluted outstanding common shares upon the closing of the Private Placement. The option exercise price for this second option grant shall be equal to the
greater of: (i) the option exercise price for the April 2003 option grant or (ii) 25% of the fair market value of a share of our Common Stock on the date of grant for the second option grant. Additionally, the employment agreement provides that Mr.
Limber is eligible to receive a performance stock option grant, with a per-share exercise price equal to the fair market value of a share of our Common Stock on the date of grant, equal to 2% of our fully-diluted outstanding common shares at the
time of such performance option grant, provided, however, that such performance option grant shall only be awarded upon the successful achievement of specified Deltagen performance milestones. The terms and conditions of the subsequent option grants
shall be generally comparable to the terms for the initial April 2003 option grant to Mr. Limber. All of the option grants to Mr. Limber are to be issued pursuant to our 2000 Stock Incentive Plan (the Plan) and are expressly conditioned
on compliance with



96

##### Table of Contents

the Plans annual equity grant limits. To the extent an option grant to Mr. Limber is limited by the Plans equity grant limits,
then such unawarded excess grant amount shall be granted in a subsequent fiscal year (subject again to the Plans annual grant limits) with the vesting of such option commencing as of the date that the option was originally intended to have
been granted on. Any such deferred option grants shall have an exercise price equal to what the exercise price would have been had the option been granted earlier but for the Plans grant limits, provided, however, that the per-share exercise
price shall in no event be lower than 25% of the fair market value of a share of our Common Stock on the actual date of grant. Under the employment agreement, Mr. Limber is also eligible to participate in all our equity incentive plans and other
employee benefit plans and he will accrue three weeks paid vacation annually.



If we terminate Mr. Limbers employment without Cause (as defined in the employment agreement) or if he is Constructively Terminated (as defined in the employment agreement), then Mr. Limber shall
be eligible to receive payments equal to his then annual base salary for the twelve months following his termination of employment. If such termination of employment without cause or constructive termination occurs within one year after a Change in
Control of Deltagen (as defined in the employment agreement) then, in addition to the twelve months of salary continuation payments, Mr. Limber shall also receive a pro-rated portion of his annual target cash incentive bonus amount and all of his
unvested stock options shall become vested.



Dr.
Matthews was a party to an employment agreement, dated April 7, 2000 and subsequently amended on June 26, 2002, pursuant to which Dr. Matthews served as Chief Executive Officer and President. Dr. Matthews also served as Chairman of the Board until
his resignation from his position as Chairman effective November 22, 2002. Dr. Matthews employment agreement was superseded by a transition agreement between Dr. Matthews and Deltagen, dated January 20, 2003, pursuant to which Dr. Matthews
continued to serve as Chief Executive Officer and as a member of the Office of the Chairman while Deltagen conducted a search for a new Chief Executive Officer. Pursuant to the transition agreement, Dr. Matthews received an annual salary of
$400,000, his unvested stock options having a per-share exercise price greater than Deltagens closing share price on the execution date of the transition agreement were vested in full and his promissory note to Deltagen was retired for
consideration as discussed further in the Management Indebtedness section below. The transition agreement also provides for an aggregate amount of $400,000 paid in monthly installments to Dr. Matthews over the one year following his termination of
employment, provided, however, that such amount would be reduced as necessary to satisfy his promissory note obligation. In addition, the transition agreement provides that Dr. Matthews would continue to serve Deltagen as a consultant for one year
following his termination of employment. Dr. Matthews resigned his employment on February 12, 2003, and he began serving as a consultant pursuant to a consulting agreement that will expire on February 13, 2004. For services rendered under the
consulting agreement, Dr. Matthews will receive compensation at an annual rate of $225,000, paid monthly, and his outstanding stock options shall continue to vest and be exercisable while he provides such consulting services.



Mr. Hawkins is party to an employment agreement dated February
13, 2003. The agreement will expire on December 31, 2004 but will automatically renew for additional one-year term after that date. The agreement provides for an annual base salary of $50,000 until March 31, 2003 and accelerated vesting of equity
grants in the event of a change of control of our company. The annual base salary increased to $400,000 on April 1, 2003 and decreased to $340,000 on April 2, 2003 when the Office of the Chairman was dissolved. In addition, Mr. Hawkins is
entitled to an annual bonus to be determined by the Board of Directors. In the event Mr. Hawkins is terminated without cause or constructively terminated he will be entitled to severance equal to twelve months of his base salary.



Dr. Moore is party to an employment agreement dated April 8,
2000. The agreement will expire on April 8, 2003 but will automatically renew for additional one-year terms after that date unless either we or Dr. Moore give notice to not renew the agreement at least ninety days prior to the expiration of the then
existing term. The agreement provides for an initial annual salary of $225,000 and accelerated vesting of all of Dr. Moores options in the event of a change in control of our company. In addition, Dr. Moore is entitled to an annual bonus to be
determined by the Board of Directors. In the event that Dr. Moore is terminated without cause, he will be entitled

to receive severance equal to six months of his base salary. Dr. Moore is also party to an agreement dated February 14, 2003 pursuant to
which the promissory note between Dr. Moore and Deltagen described in the Management Indebtedness section below was satisfied and pursuant to which he receives a monthly retention bonus of $15,000 until November 14, 2003.



We hired Mr. John W. Varian to become our Interim Chief
Financial Officer (ICFO) pursuant to an offer letter agreement dated April 16, 2003. Mr. Varian had provided consulting services to Deltagen in 2003 prior to his hire. Pursuant to this offer letter, upon the closing of the preferred
stock private placement, Mr. Varian will become our Chief Financial Officer (CFO). The offer letter agreement provides that Mr. Varian will serve three-quarters-time in an at-will capacity as our ICFO/CFO. For such services, Mr. Varian
will earn an annual base salary of $195,000 which shall be subject to review and adjustment by the Board of Directors. Mr. Varian will be eligible to earn an annual cash bonus of up to 30% of his annual base salary based upon accomplishment of
specified performance objectives. The actual amount of any bonus awarded, if any, shall be determined by the Board of Directors. The offer letter also provides that Mr. Varian is eligible to receive a stock option grant to purchase up to 1.75% of
our outstanding Common Stock, measured immediately after the closing of the preferred stock private placement on a fully-diluted basis, at a per-share price equal to the fair market value of a share of our Common Stock on the date of grant. Subject
to Mr. Varians continued employment with Deltagen, fifty percent of the shares subject to the option will vest pro-rata on a monthly basis over the twelve months following Mr. Varians employment start date and the remaining fifty
percent of the shares subject to the option will vest pro-rata on a monthly basis over the three year period following the first anniversary of his employment start date. The option grant to Mr. Varian is to be issued pursuant to our 2000 Stock
Incentive Plan (the Plan) and is subject to all Plan terms. Under the offer letter, Mr. Varian is also eligible to participate in the Companys employee benefit plans and he will accrue three weeks paid vacation annually. If Mr.
Varian remains continuously employed by the Company through the effective date of a Change in Control of Deltagen (as defined in the offer letter) or if his employment is terminated without Cause (as defined in the offer letter) in connection with a
Change in Control of Deltagen, then Mr. Varian shall be eligible to (i) receive a one-time cash payment equal to 130% of his then annual base salary and (ii) have the vesting of his unvested stock options fully accelerated.



Mr. Burke was party to an employment agreement dated April 7,
2000. The agreement was to expire on April 7, 2003 but automatically renews for additional one-year terms after that date unless either we or Mr. Burke give notice to not renew the agreement at least ninety days prior to the expiration of the then
existing term. The agreement provides for an initial annual salary of $175,000 and accelerated vesting of a portion of Mr. Burkes options in the event of a change in control of our company, unless more than 50% of his options have already
vested. In addition, Mr. Burke is entitled to an annual bonus to be determined by the Board of Directors. In the event that Mr. Burke is terminated without cause, he will be entitled to receive severance equal to six months of his base salary. Mr.
Burkes employment ended on April 10, 2003.



Mr. Yee was party to an employment agreement dated April 7, 2000. The agreement provided for an initial annual salary of $175,000 and accelerated vesting of a portion of Mr. Yees options in the event of a change in control of
our company, unless more than 50% of his options have already vested. In addition, Mr. Yee was entitled to an annual bonus to be determined by the Board of Directors. In the event that Mr. Yee was terminated without cause, he would have been
entitled to receive severance equal to six months of his base salary. Mr. Yees employment ended on February 26, 2003, at which time Mr. Yee entered into a separation agreement with Deltagen under which Deltagen was obligated to pay severance
for a two month period.



The Private Placement
will not trigger any change of control provisions of the employment agreements described above.

CHANGE IN CONTROL AGREEMENTS



On June 26, 2002 upon recommendation of the Compensation Committee, the Board of Directors unanimously approved the Deltagen, Inc. Change of Control Severance Pay Plan for Non-Officers and the Deltagen, Inc. Change of Control
Severance Pay Plan for Officers (the Officer Plan). Under these plans our employees are granted severance benefits if they are terminated for any reason other than cause or terminate their employment because of good
reason within twelve (12) months of a change of control. The Officer Plan is applicable to all of our vice presidents and executive officers, including the named executive officers. The Private Placement will not trigger any change
of control severance obligations under these plans.



The Officer Plan defines a change of control as the occurrence of either of the following events: (a) a change in the composition of our Board, as a result of which fewer than one-half of the incumbent directors are
directors who either: (i) had been directors twenty-four (24) months prior to such change; or (ii) were elected, or nominated for election, to the Board with the affirmative votes of at least a majority of the directors who had been directors
twenty-four (24) months prior to such change and who were still in office at the time of the election or nomination; or (b) any person (as such term is used in sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended)
who by the acquisition or aggregation of securities, is or becomes the beneficial owner, directly or indirectly, of our securities representing fifty percent (50%) or more of the combined voting power of our then outstanding securities ordinarily
(and apart from rights accruing under special circumstances) having the right to vote at elections of directors (the Base Capital Stock); except that any change in the relative beneficial ownership of our securities by any person
resulting solely from a reduction in the aggregate number of outstanding shares of Base Capital Stock, and any decrease thereafter in such persons ownership of securities, shall be disregarded until such person increases in any manner,
directly or indirectly, such persons beneficial ownership. For purposes of this definition, the term person does not include an employee benefit plan we maintain. Notwithstanding the foregoing, the term change of
control shall not include a transaction, the sole purpose of which is to change the state of our incorporation.



For purposes of the Officer Plan, cause means (a) any intentional action or intentional failure to act by an officer which was
performed in bad faith and to our material detriment; (b) the willful and habitual neglect of the officers duties of employment; or (c) the conviction of an officer of a felony crime involving moral turpitude. Good reason is
defined in the Officer Plan as actions which (a) reduce the powers, duties or title of an officer; (b) reduce the officers base salary; or (c) require the officer to relocate his or her principal place of business by more than 40 miles from
its location immediately prior to the change of control.



Benefits under the Officer Plan consist of a lump-sum severance payment of six (6) months regular base pay; the pro rata portion of any annual bonus; reimbursement of health care continuation coverage premiums for the six (6) month
period following termination of the officers employment; and forgiveness of unpaid portions of the officers relocation loan. The severance benefits payable under the Officer Plan are contingent on the officer granting a release of claims
to us and are reduced to the extent that they are duplicative of benefits that an officer may have under a written employment agreement.



Under the Officer Plan, we reserved the right to amend or terminate the plan at any time without the consent of any officer. However,
within the period commencing six (6) months prior to a change of control and ending eighteen (18) months after a change of control, consent of any affected officer to an amendment or termination of the plan would be required if the affect of the
amendment or termination would be to reduce the benefits the officer would otherwise have been eligible to receive under the terms of the plan.



Compensation Committee Interlocks and Insider Participation



The Compensation Committee currently consists of Dr. Chambon, Mr. Penn and Mr. Perry. No member of the Compensation Committee was an officer or employee of Deltagen or any of its subsidiaries during
fiscal year 2002 nor was formally an officer of Deltagen or any of its Subsidiaries. None of the executive officers of Deltagen has served on the Board of Directors or on the compensation committee of any other entity, any of whose officers served
either on the Board of Directors or on the Compensation Committee of Deltagen.

COMPENSATION COMMITTEE REPORT



The Compensation Committee of the Boardthe Committeedetermines the compensation of executive officers. It has provided you with this report to help you to understand the goals, policies and procedures it follows in making
its determinations.



The Board established the
present Committee, which currently consists of the 3 outside directors whose names appear at the end of this report, on April 9, 2000 in contemplation of the initial public offering.



In establishing and administering compensation policies and programs after the initial public offering, the
Committee considered the compensation policies and arrangements established by Deltagen before the initial public offering, including the levels of individual compensation, and commitments made by Deltagen and the Board before the initial public
offering as well as factors relevant to Deltagen after the initial public offering.



The Committees executive compensation philosophy has been and continues to be that compensation programs should:



| |  |  | be closely aligned with the interest of the stockholders;
| | - |  | ---------------------------------------------------------



| |  |  | be linked with business goals and strategies;
| | - |  | ---------------------------------------------



| |  |  | be competitive within our industry and community so that we can attract and retain high quality executives;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | base a substantial portion of executive officer compensation on our operating performance measured against pre-determined objectives; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | reward executive officers for good performance.
| | - |  | -----------------------------------------------



Compensation of executive officers, including the Chief Executive Officer, is comprised of four elementsbase salary, annual bonuses,
stock ownership and other compensation.



Base Salaries



Base salary is designed primarily to provide compensation at competitive levels so as to attract and retain the executive.



Annual Incentive Awards



We also have created annual incentives for executive officers through potential cash awards under an incentive plan intended to link
compensation to operational performance.



Stock Options



We
believe that executive officers and other employees who are in a position to make a substantial contribution to our long-term success and to build stockholder value, should have a significant stake in our on-going success. As a result, we have
granted incentive stock options and non-qualified stock options under incentive stock plans in order to retain talented executive officers and to align their compensation with stockholder value. Because the stock options have an exercise price equal
to the market price of our stock on the grant date and generally vest in equal installments over four years assuming continued employment, stock options compensate executive officers only if the stock price increases after the date of grant and the
executive officer remains employed for the periods required for the stock option to become exercisable.



Other Compensation



To attract and retain talented executive officers, the Committee also has approved arrangements giving executive officers certain
perquisites, such as disability insurance.



100

##### Table of Contents



Tax
Deductibility of Executive Compensation



Section 162(m) of the Internal Revenue Code generally provides that publicly held corporations may not deduct in any taxable year certain compensation in excess of $1,000,000 paid to the chief executive officer and the next four most
highly compensated executive officers. However, the Committee considers one of its primary responsibilities to be structuring a compensation program that will attract, retain and reward executive talent necessary to maximize stockholder return.
Accordingly, the Committee believes that Deltagens interests are best served in some circumstances by providing compensation (such as salary, perquisites and special cash bonuses) which might be subject to the tax deductibility limitation of
Section 162(m).



Bases for CEO Compensation



The Committee followed generally the
same policies and programs described above for compensation of executive officers in determining fiscal year 2002 compensation for Dr. Matthews as President and Chief Executive Officer.

In March 2000, we issued 342,856 shares of Common Stock to Dr. Matthews in exchange for a full recourse promissory note of $536,700. The promissory note was collateralized by the 342,856 common shares and accrued interest at 6.8% per
