OVERVIEW

        We believe that Lynx Therapeutics, Inc. is a leader in the development
and application of novel technologies for the discovery of gene expression
patterns and genomic variations important to the pharmaceutical, biotechnology
and agricultural industries. Gene expression patterns refer to the number of
genes and the extent a cell or tissue expresses those genes, and they represent
a way to move beyond DNA sequence data to understand the function of genes, the
proteins that they encode and the role they play in health and disease. Genomic
variations refer to the differences in the genetic sequences in the genomes of
different organisms. Megaclone, our unique and proprietary cloning procedure,
forms the foundation of these technologies. Megaclone transforms a sample
containing millions of DNA molecules into one made up of millions of
micro-beads, which are microscopic beads of latex, each of which carries
approximately 100,000 copies of one of the DNA molecules in the sample. In
contrast to conventional cloning, in which an individual DNA molecule is
selected from a sample and amplified into many copies for analysis or
identification, we can capture on one set of micro-beads clones of nearly all
the DNA sequences that characterize a sample. Once attached to the micro-beads,
these clones can be handled and subjected to experiments and analyses all at the
same time. Megaclone thereby enables many analyses or characterizations to be
conducted that would otherwise be too cumbersome or onerous to conduct using
conventional procedures where each clone must be addressed individually. Based
on Megaclone, we have developed a suite of applications that have the potential
to enhance the pace, scale and quality of genomics and genetics research
programs. Lynx's current commercial collaborators and customers are BASF AG,
E.I. DuPont de Nemours and Company, Aventis CropScience GmbH, Oxagen Limited,
Hybrigenics S.A., Genomics Collaborative Inc., Molecular Engines Laboratories
SA, the Institute of Molecular and Cell Biology, Phytera, Inc., Celera Genomics,
AstraZeneca, UroGene S.A., GenoMar ASA and AniGenics, Inc. Additionally, Lynx
has provided a license for the use of certain of our technologies to Takara
Shuzo Co. Ltd. and BASF-LYNX Bioscience AG (BASF-LYNX).

        Technologies we have developed that leverage the power of Megaclone are:

        -       Massively Parallel Signature Sequencing, or MPSS, which
                generates simultaneously, from a million or more Megaclone
                micro-beads, gene sequence information that uniquely identifies
                a sample's DNA molecules without the need for individual
                conventional sequencing reactions, and produces a comprehensive
                quantitative profile of gene expression in cells or tissues;

        -       Megasort, which enables researchers to focus on potential
                target genes by permitting, from a single experiment, the direct
                physical isolation of nearly all the genes differentially
                expressed between samples; and

        -       Megatype, which, when fully developed, should enable a single
                experiment to yield directly those disease- or trait-associated
                single nucleotide polymorphisms, also known as SNPs, that
                differentiate large populations of genomes. SNPs are single
                nucleotide variations, or differences occurring in a single
                subunit of DNA or RNA, in the genetic code that occur at every
                1,000 bases along the three billion nucleotides in the human
                genome. Megatype experiments would not require genotyping, which
                is the process of testing entire individual genomes for the
                presence or absence of a set of SNPs.

        We are developing additional applications of these technologies, as well
as new technologies aimed at addressing the needs of the pharmaceutical,
biotechnology and agricultural industries. For example, we are working on a new
separation technology in the area of proteomics, which is the study of the
number of proteins and the extent to which they are expressed in cells or
tissues, to provide high-resolution analysis of complex mixtures of proteins
from cells or tissues of interest.

        In addition to our and our licensee's work with collaborators and
customers, we intend to apply our suite of technologies in selected biological
areas to develop products internally to discover and then license or sell gene
targets, validated gene targets, genetic associations, genomic maps and other
products. For example, we are pursuing projects directed to gene discovery and
target validation in immunopathology and, through BASF-LYNX, our joint venture
with BASF, central nervous system disorders.

INDUSTRY BACKGROUND

        The publication of the first draft sequence of the human genome was a
milestone in the history of genetics and genomics. However, the remaining
challenge for researchers in industry and academia alike is to explore the
multitude of genomic variations and to discover, from the analysis of these
differences, the functions of genes and their roles in health and disease. It is
this work, post genome-sequencing, that is expected to lead to commercial
opportunities and ultimately to the discovery of new therapies for unmet medical
needs and to provide the basis for the emerging fields of pharmacogenetics,
which is the identification and assessment of genes that are predictive of
efficacy and toxicity of drug compounds or that may correlate drug responses to
individual genotypes, and individualized patient therapy.

        Many diseases result from a malfunction of the genetically programmed
protective response to insults, such as trauma, infection, stress or an
inherited mutant gene. That malfunction may result in inadequate, misguided or
exaggerated gene expression, unfolding a complex pathogenic process which may
resolve itself, linger chronically or evolve with increasingly destructive
effects in a manner quite removed from, and even independent of, the original
insult. By analyzing which genes are expressed in a cell or tissue, the level of
expression can illustrate which physiological pathways are active in the cell
and to what degree. By understanding when and where abnormal gene expression
occurs and the changes in expression that a drug can cause, the physiological
pathways implicated in disease and drug action can be pinpointed. This knowledge
could be used to help discover drug targets, screen drug leads, predict a
compound's toxic effects, anticipate pharmacological responses to drug leads and
tailor clinical trials to the specific needs of subgroups within a population.
By recognizing gene expression patterns, researchers, and ultimately physicians,
may also be able to determine which treatments are likely to be effective for a
specific condition and which may be ineffective or harmful.

        Genomic approaches to therapeutics seek to identify genes connected to
the origin of a disease. Searches to identify such genes generally are laborious
and involve a very large amount of conventional DNA sequencing to identify genes
or gene fragments. This knowledge of genes is a first step only. While it may
pave the way for the development of better diagnostics, it may not necessarily
lead to a successful therapy. For example, while a particular gene, or absence
of a gene, may predispose a person to a cancer, an entirely different set of
genes is likely to govern the tumor and its metastases. Hence, in addition to
understanding the cause of disease, it is important to understand entire
networks of genes and their functions in both healthy and diseased states in
order to identify the optimal targets for therapy.

        One approach to genomics research is based on the study of gene
expression and regulation of gene expression in cells in differing states or
conditions. Gene expression in a cell consists of transcription, the process
which converts the genetic information encoded in the double-stranded DNA of a
gene into mRNA, and translation, the process which converts the genetic
information encoded in mRNA into a specific protein molecule. At any one time,
any particular human cell expresses thousands of genes. A different number of
copies of each mRNA type will be present in each sample depending upon the
particular cell, its function and its environmental conditions at the time.
Thus, a cell will contain, at any one time, tens of thousands of different
mRNAs, in various quantities, for a total on the order of one million or more
mRNA molecules.

        Elucidating gene function involves not only determining which genes are
expressed in a healthy or diseased tissue, but also requires determining which
of the altered gene expressions cause a disease rather than result from the
disease. In general, only the most abundantly expressed genes are currently
accessible using conventional methods. In addition, conventional methods are
dependent on separating and cloning double-stranded copies of each individual
mRNA, or cDNA, prior to analysis. Thus, by conventional methods, it is
impractical to obtain a comprehensive, high-resolution analysis of gene
expression across one million or more mRNA molecules in cells of interest to the
researcher.

        Another approach to genomics research is based on the study of human
genetic variations. It is well known that the incidence of human diseases and
their severity differ in different groups and individuals. There are many common
diseases in which several genes play a role in the initiation and development of
the pathological process, as well as in the responses of the individual to a
therapy. This approach studies gene association with diseases by using a large
assembly of specific gene variants called polymorphisms. The most abundant of
these are single nucleotide polymorphisms, or SNPs, which are single-base
mutations in the genome. A SNP is found, on average, once in every 1,000 bases.
This means if any two individuals are compared, their genomes will be found to
differ at more than one million places. Genotyping refers to the process of
testing individual genomes for the presence or absence of a set of SNPs.

        If a SNP correlation to a disorder is proven, it would point to those
regions of the genome in which the sequences responsible for the disorder may be
located. However, to discover such regions, it is currently believed that one
would have to test several hundred individual genomes for the presence or
absence of tens of thousands, if not more, SNPs. Thus, there is a real need to
employ a technology that can quickly and efficiently determine which of these
thousands of SNPs are significantly associated with diseases in large
populations of patients and thereby provide a relevant set of SNPs for
downstream genotyping of individuals.

OUR SOLUTION

        We overcome many of the limitations of current technologies by capturing
essentially all of the different DNA molecules in a sample on micro-beads using
our Megaclone technology and applying our various analytical technologies to
conduct relevant comparisons and other analyses of the captured DNA molecules.
Thus, our patented Megaclone technology enables an automated, high-throughput
analysis of complex mixtures of DNA molecules.

        Megaclone is a process that uses a proprietary library of approximately
16.7 million short synthetic DNA sequences, called tags, and their complementary
anti-tags, to uniquely mark and process each DNA molecule in a sample. Each
unique tag is a permanent identifier of the DNA molecule it is attached to, and
all of the tagged molecules in a sample are amplified together to create
multiple copies of the tagged molecules. We use another proprietary process to
generate five micron diameter micro-beads, each of which carries multiple copies
of a short anti-tag DNA sequence complementary to one of the 16.7 million tags.
Then we collect the amplified tagged DNA molecules onto the micro-beads through
hybridization of the tags to the complementary anti-tags. Each micro-bead
carries on its surface enough complementary anti-tags to collect approximately
100,000 identical copies of the corresponding tagged DNA molecule.

        By this process, each tagged DNA molecule in the original sample is
converted into a micro-bead carrying about 100,000 copies of the same sequence.
Therefore, in a few steps, our Megaclone technology can transform a complex
mixture of a million or more individual DNA molecules into a usable format that
provides the following benefits:

        -       substantially all the different DNA molecules present in a
                sample are represented in the final micro-bead collection;

        -       these million or more DNA molecules can be analyzed
                simultaneously in various applications; and

        -       the need for storing and handling millions of individual DNA
                clones is eliminated.

Megaclone is the foundation for our analytical applications, including MPSS,
which provides gene sequence information and high-resolution gene expression
information, Megasort, which provides focused sets of differentially expressed
genes and potential gene targets, and Megatype, which is expected to provide SNP
disease- or trait-association information.

OUR BUSINESS STRATEGY

        We intend to apply our technologies to maximize the value of human,
animal and plant genomic information for our licensee, collaborators and
customers and ourselves through high-resolution gene expression analysis and in
the discovery and characterization of important genetic variations. Now that we
have reduced to practice the majority of our technologies, we intend to enlarge
our presence in the pharmaceutical, biotechnology, agricultural and other
commercially important markets. We believe many drug discovery and development
companies now recognize the need for significantly greater resolution and scope
in their genomics and genetics research.

        The primary elements of our business strategy are:

        -       Pursue selected internal programs to capture greater value

        We intend to use our technologies to discover and develop gene targets,
validated gene targets, genetic associations, genomic maps or other products in
selected fields. Through these internal programs, we will endeavor to create
valuable drug discovery information and related intellectual property that we
could license to third parties. If successful, we could realize revenues from
licensing our discoveries through licensing fees, milestone payments and
royalties or profit-sharing. For example, we have initiated a program directed
to the discovery and validation of targets in the field of immunopathology.

        -       Collaborate with others with whom we can create value

        We will seek to collaborate with companies and research institutions
under arrangements in which we provide access to our technologies, and our
collaborators provide access to well-defined clinical samples and/or biological
expertise. Through these programs, we will endeavor to create valuable drug
discovery information and related intellectual property that could be licensed
to third parties. If successful, we could realize revenues through a share in
any licensing or commercialization by us or our collaborators.


                                       3


<PAGE>   6
        -       Provide high-resolution gene expression information for use in
                databases

        We intend to use our technologies, particularly MPSS, to produce
high-resolution gene expression information from cells or tissues for inclusion
in databases. We believe the distinguishing feature of the information that Lynx
could produce is that it represents a comprehensive quantitative profile of gene
expression in cells or tissues. Our approach could be either to assemble this
information on our own or with a partner in a database format, accessible to
others for an access fee and/or continuing subscriptions, or to provide this
information to others for inclusion in their existing database products, in
return for services fees in producing the information and/or a share of the
revenues or profits from the commercialization of the database.

        -       Provide high-resolution gene expression information for the
                specific programs of others

        With the assumed accessibility to databases containing high-resolution
gene expression information on cells or tissues for comparative purposes, we
expect that pharmaceutical, biotechnology, agricultural and other companies will
engage us to produce a comprehensive quantitative profile of gene expression in
cells or tissues for their specific interests, such as in diseased, abnormal or
induced states or conditions. In these arrangements, we could provide
information content for each company's specific internal database or programs.
In return, we could earn services fees in producing the information and/or a
share of the revenues or profits from the commercialization of a product
stemming from the use the information by the company.

        -       Continue to grow our genomics discovery services

        We have generated revenues through agreements for genomics discovery
services. We plan to continue to provide such services to pharmaceutical,
biotechnology and agricultural companies for use in their discovery, development
and commercialization efforts. The revenue sources from these arrangements
typically include technology access and services fees. We have provided a
license for the use of certain of our technologies to Takara. The license
provides Takara with the right in Japan, Korea and China, including Taiwan, to
use our technologies exclusively for at least five years, and non-exclusively
thereafter, to provide genomics discovery services and to manufacture and sell
microarrays (small glass or silicon wafers with tens of thousands of DNA
molecules arrayed on the surface for subsequent analysis) containing content
identified by our technologies. Takara also receives from us a non-exclusive
license right to manufacture and sell such microarrays elsewhere throughout the
world.

        -       Develop new technologies and additional applications of our
                technologies

        We intend to continue to develop creative solutions to complex
biological problems. We currently focus on reducing to commercial practice our
Megatype technology in order to extract from large populations those genomic
fragments exhibiting SNPs and associate these SNPs with traits or diseases. We
may further develop our technology to apply it to individual genotyping, which
would determine the relevant SNPs present in an individual. We are also working
in the area of proteomics to provide a means of high-resolution analysis of
complex mixtures of proteins from cells or tissues.

OUR TECHNOLOGIES AND APPLICATIONS

        We have developed, or are developing, several important analytical
applications of our Megaclone technology to better address the need for
increased pace, scale and quality of genomics and genetics research programs.

Current Applications

        Massively Parallel Signature Sequencing Technology. Our MPSS technology
addresses the need to generate sequence information from millions of DNA
fragments. At this extremely large scale, our MPSS approach eliminates the need
for individual sequencing reactions and the physical separation of DNA fragments
required by conventional sequencing methods.

        MPSS enables the simultaneous identification of nearly all the DNA
molecules in a sample. MPSS uses flow cells which are glass plates that are
micromachined, or fabricated to very precise, small dimensions, to create a
grooved chamber for immobilizing microbeads in a planar microarray, which is a
two-dimensional, dense ordered array of DNA samples. With MPSS, one million or
more Megaclone micro-beads are fixed in a single layer array in a flow cell, so
solvents and reagents can be washed over the micro-beads in each cycle of the
process. Our proprietary protocol elicits from the Megaclone micro-beads
sequence-dependent fluorescent responses, which are recorded by a charged
coupled device, or CCD, camera after each cycle. The process produces short 16-
to 20-base-pair signature, or identifying, sequences, without requiring fragment
separation and separate sequencing reactions as in conventional DNA sequencing
approaches. We have developed proprietary instrumentation and software to
automate the delivery of reagents and solutions used in our sequencing process
and to compile, from the images obtained at each cycle, the signature sequences
that result from each experiment.


                                       4


<PAGE>   7
        We believe MPSS has the following advantages over conventional DNA
sequencing methods:

        -       it sequences DNA molecules on as many as one million or more
                Megaclone beads simultaneously;

        -       it eliminates the need for individual sequencing reactions and
                gels;

        -       it identifies each of the DNA molecules by a unique 16- to
                20-base signature sequence;

        -       it produces a comprehensive quantitative profile of gene
                expression in cells or tissues of interest; and

        -       it identifies even the rarest expressed genes.

        We currently have over 30 operational proprietary MPSS instruments. We
are utilizing MPSS to generate high-resolution expression data in several
biological systems for our collaborators and customers and for ourselves. These
data are being derived from tissues and samples that have been prioritized by
our collaborators and customers, in addition to those identified by our research
teams for our internal programs. We will also generate data that can be
delivered directly to our customers to identify new genes and otherwise enhance
their databases.

        MPSS delivers gene sequence information and high-resolution gene
expression information and could enable the construction of high-resolution gene
expression databases from cells or tissues of interest.

        Megasort Technology. Our Megasort technology provides a method to
identify and physically extract essentially all genes that differ in expression
level between two samples. The novelty of Megasort is that the identification
and extraction are performed in a single assay.

        Megasort compares two DNA samples, each containing millions of
molecules, and extracts those DNA molecules that are present in different
proportions in the samples. These could be differentially expressed genes or DNA
fragments that are found in one sample but not the other. Because the comparison
and sorting require no prior knowledge of the sequences of the genes in either
sample, Megasort can be used with samples isolated from tissues or organisms
that are not well characterized. Megasort involves hybridizing two probes
prepared separately, one from each of the samples to be compared, with a
population of Megaclone micro-beads, each of which carries many copies of a
single DNA fragment or gene derived from either of the samples. Because each
probe is labeled with a different fluorescent marker, we can readily separate by
a fluorescence activated cell sorter, also referred to as a FACS, genes or
fragments that are under- or over-represented in either sample. Genes or
fragments of interest can then be recovered from the sorted micro-beads for
further study.

        Megasort technology uses Megaclone micro-beads as a "fluid" microarray.
In a single experiment, Megasort can isolate nearly all the potential target
genes that are differentially expressed, and remove those that do not differ
between the samples. We believe Megasort has the following advantages over
conventional gene microarrays:

        -       it interrogates all the expressed genes, including rarely
                expressed genes, in the two samples being compared, whether
                known or not;

        -       it does not require advance knowledge about any of the genes in
                these samples; and

        -       it extracts, at the end of the experiment, physical DNA clones
                of those genes that are of interest attached to the micro-beads
                that were sorted.

Megasort delivers focused sets of differentially expressed genes and potential
gene targets.

Technologies, Applications and Products Under Development

        Megatype Technology. We believe our Megatype technology will permit the
comparison of collected genomes of two populations. It is designed to enable the
detection and recovery of DNA fragments with the SNPs that distinguish these two
populations. In contrast to other SNP validation methods that require thousands
or millions of assays, only a single Megatype experiment should be required for
SNP association with disease or other traits.


                                       5


<PAGE>   8
        Megatype is designed to identify SNPs that are differentially
represented in two populations of individuals. We use a proprietary method to
select DNA fragments that exhibit a specific class of SNPs in the combined
populations and to load the fragments onto micro-beads with our Megaclone
technology. Using fluorescently labeled probes, prepared through the same
proprietary method, from the two separate populations, micro-beads bearing
SNP-containing fragments that are under- or over-represented in either of the
two populations are easily separated using the FACS. No prior knowledge of the
SNP sequences or where they are located in the genome is required to conduct
this analysis.

        We believe the advantages of Megatype will include:

        -       enabling simultaneous discovery of disease- or trait-associated
                SNPs without prior knowledge of SNP sequences;

        -       identifying, in a single experiment, the genetic differences
                that distinguish large populations;

        -       extracting fragments containing over- or under-represented SNPs
                in different populations;

        -       eliminating the need for millions of individual genotyping
                assays to determine SNP disease association; and

        -       bypassing the prior need for a comprehensive SNP map.

We believe our Megatype technology will deliver information on the disease- or
trait-association of SNPs and should provide a cost-effective approach to drug
discovery and pharmacogenetics.

        Proteomics. Proteomics is the study of the entire protein complement in
cells. Our proteomics technology aims to provide high-resolution analysis of
complex mixtures of proteins from cells or tissues. Based on solution-phase
electrophoresis in proprietary micro-channel plates, the approach combines the
speed of capillary electrophoresis, the process by which electronically charged
molecules are separated by their different mobilities in an electric field, with
the resolving power of conventional two-dimensional gel-based techniques. Using
this technology, we expect to complement high-resolution gene expression
measurements using our MPSS platform with similar high-resolution analysis of a
cell's translated proteins. The combined data from these measurements should
provide a much more accurate and comprehensive picture of cell and tissue
physiology than is available using current techniques. Our goal is to use our
proteomics technology to discover drug targets, validate candidate targets and
correlate gene expression with protein expression in cells.

        Genotyping. As a natural extension of our Megatype technology, we may
further apply the technology to individual genotyping, which would determine the
relevant SNPs present in an individual. This application will attempt to derive
more of the downstream value from the scientifically relevant SNPs through the
additional enabling of trait selection in crops, and predictive or preventative
medicine in humans, thus moving closer to the notion of "personal genomics."
Furthermore, we may develop additional assays to help link associated SNPs
initially identified by Megatype technology to specific genes responsible for
the observed traits.

  BASF

        In October 1996, as amended in October 1998, Lynx entered into an
agreement with BASF to provide them with nonexclusive access to certain of our
genomics discovery services. In connection with certain technology development
accomplishments, BASF paid us a technology access fee of $4.5 million in the
fourth quarter of 1999. BASF's access to Lynx's genomics discovery services is
for a minimum of two years and requires BASF to purchase services at a minimum
rate of $4.0 million per year. At the end of the initial two-year service
period, BASF has the right to carryover for a limited time a certain level of
previously unrequested genomics discovery services. BASF paid us $4.0 million
in each of the fourth quarters of 1999 and 2000 for genomics discovery services
to be performed by us.

  DuPont

        In October 1998, Lynx entered into a research collaboration agreement
with DuPont to apply our technologies on an exclusive basis to the study of
certain crops and their protection. Under the terms of the agreement, the
Company could receive payments over a five-year period for genomics discovery
services, the achievement of specific technology milestones and the delivery of
genomic maps of specified crops. An initial payment of $10 million for
technology access was received at the execution of the agreement, with
additional minimum service fees of $12 million to be received by us over a
three-year period that commenced in January 1999. At the end of three years from
the effective date of the agreement, DuPont can terminate the agreement either
with no further payment obligations to Lynx other than those accrued, or if
DuPont chooses to maintain exclusivity with respect to certain crops, with
payments for the remaining two years of the agreement. In the fourth quarter of
1999, Lynx achieved a technology milestone under the agreement that resulted in
a $5 million payment from DuPont.

  Aventis CropScience

        In March 1999, Aventis Pharmaceuticals, formerly Hoechst Marion Roussel,
Inc., obtained nonexclusive access to certain of our genomics discovery services
for the benefit of its affiliate, Aventis CropScience. Lynx received an initial
payment for genomics discovery services to be performed by us for Aventis
CropScience. The service period, which was renewed in March 2000, has been
extended to September 2001, and is subject to renewal for up to two additional
one-year periods.

        In September 1999, Lynx signed a three-year research collaboration
agreement with Aventis CropScience. Aventis CropScience will receive exclusive
access to certain of our genomics discovery services for the study of certain
plants, which is aimed at developing new crop varieties and other agricultural
products. Under the terms of the agreement, Aventis CropScience paid us a
technology access fee upon execution of the agreement. Lynx can earn additional
fees for the performance of genomics discovery services, the delivery of genomic
maps of certain plants and milestone payments and licensing fees related to the
discovery of trait-associated SNPs for the subject plants.

<PAGE>   10

  Takara

        In November 2000, Lynx entered into a technology licensing agreement
with Takara Shuzo Co. Ltd. of Japan. The license provides Takara with the right
in Japan, Korea and China, including Taiwan, to use our proprietary Megaclone,
Megasort and MPSS technologies exclusively for at least five years, and
non-exclusively thereafter, to provide genomics discovery services and to
manufacture and sell microarrays containing content identified by our
technologies. Takara also receives a non-exclusive license right to manufacture
and sell such microarrays elsewhere throughout the world. At the end of three
years from the effective date of the agreement, Takara can terminate the
agreement with no further payment obligations to Lynx other than those accrued
prior to the termination. Under the terms of the agreement, Lynx will receive
from Takara payments for technology access fees, royalties on sales of
microarrays and revenues from genomics discovery services, the sale to Takara of
proprietary reagents used in applying our technologies and purchases of Lynx
common stock.

BASF-LYNX

       In June 2001, Lynx extended its technology licensing agreement with
BASF-LYNX, a joint venture company established in Heidelberg, Germany, by Lynx
and BASF in 1996. The license extends BASF-LYNX's right to use Lynx's
proprietary MPSS(TM) and Megasor(TM) technologies non-exclusively in
BASF-LYNX's neuroscience, toxicology and microbiology research programs until
December 31, 2007. The agreement also uniquely positions BASF-LYNX to apply
Lynx's technologies to specific disorders in the neuroscience field. Under the
terms of the agreement, Lynx will receive from BASF-LYNX a multi-million dollar
technology license fee. Lynx will furnish BASF-LYNX, initially without charge
and later for a fee, with Megaclone(TM) technology micro-beads, other reagents
and additional MPSS(TM) technology instruments for use in BASF-LYNX's research
programs.

        Separately, Lynx and BASF have agreed to continue their support of
BASF-LYNX's growth, including an increase of the capital reserve of BASF-LYNX.
Lynx's additional investment in BASF-LYNX will maintain Lynx's ownership
interest in BASF-LYNX at more than 40%.

       BASF-LYNX began operations in 1997 and is employing Lynx's technologies
in its neuroscience toxicology and microbiology research programs. Upon the
establishment of BASF-LYNX, Lynx contributed access to its technologies to
BASF-LYNX in exchange for an initial 49% equity ownership. BASF, by committing
to provide research funding to BASF-LYNX of DM50 million) or approximately
$23.4 million based on a August 2001 exchange rate) over a five-year period
beginning in 1997, received an initial 51% equity ownership in BASF-LYNX. In
1998, BASF agreed to provide an additional $10 million in research funding to
BASF-LYNX, of which $4.3 million was paid to Lynx for technology assets related
to a CNS program.

COMPETITION

        Competition among entities attempting to identify the genes associated
with specific diseases and to develop products based on such discoveries is
intense. We face, and will continue to face, competition from pharmaceutical,
biotechnology and agricultural companies, such as Affymetrix, Inc., Celera
Genomics Group, Incyte Genomics, Inc., Gene Logic, Inc., Genome Therapeutics
Corporation and Hyseq, Inc., academic and research institutions and government
agencies, both in the United States and abroad. Several entities are attempting
to identify and patent randomly sequenced genes and gene fragments, while others
are pursuing a gene identification, characterization and product development
strategy based on positional cloning. We are aware that certain entities are
using a variety of gene expression analysis methodologies, including chip-based
systems, to attempt to identify disease-related genes. In addition, numerous
pharmaceutical companies are developing genomic research programs, either alone
or in partnership with our competitors. Competition among such entities is
intense and is expected to increase. In order to successfully compete against
existing and future technologies, we will need to demonstrate to potential
customers that our technologies and capabilities are superior to those of
competitors.

        Some of our competitors have substantially greater capital resources,
research and development staffs, facilities, manufacturing and marketing
experience, distribution channels and human resources than us. These competitors
may discover, characterize or develop important genes, drug targets or drug
leads, drug discovery technologies or drugs in advance of our customers or us or
which are more effective than those developed by our collaborators and customers
or us. They may also obtain regulatory approvals for their


                                       8


<PAGE>   11
drugs more rapidly than our collaborators or customers will, any of which could
have a material adverse effect on our business. Moreover, our competitors may
obtain patent protection or other intellectual property rights that could limit
our rights or our collaborators' and customers' abilities to use our
technologies or commercialize therapeutic, diagnostic or agricultural products.
We also face competition from these and other entities in gaining access to
cells, tissues and nucleic acid samples for use in our discovery programs.

INTELLECTUAL PROPERTY

        We are pursuing a strategy designed to obtain United States and foreign
patent protection for our core technologies. Our long-term commercial success
will be dependent in part on our ability to obtain commercially valuable patent
claims and to protect our intellectual property portfolio. As of December 31,
2000, we owned or controlled 63 issued patents and 117 pending patent
applications in the United States and foreign countries relating to our genomics
technologies.

        In addition to acquiring patent protection for our core analysis
technologies, as part of our business strategy, we intend to file for patent
protection on sets of genes, both known and newly discovered, that have
diagnostic or prognostic applications, novel genes that may serve as drug
development targets, genetic maps and sets of genetic markers, such as SNPs,
that are associated with traits or conditions of medical or economic importance.
However, there is substantial uncertainty regarding the availability of such
patent protection.

        Patent law relating to the scope of claims in the technology field in
which we operate is still evolving. The degree to which we will be able to
protect our technology with patents, therefore, is uncertain. Others may
independently develop similar or alternative technologies, duplicate any of our
technologies, and, if patents are licensed or issued to us, design around the
patented technologies licensed to or developed by us. In addition, we could
incur substantial costs in litigation if we are required to defend ourselves in
patent suits brought by third parties or if we initiate such suits.

        With respect to proprietary know-how that is not patentable and for
processes for which patents are difficult to enforce, we rely on trade secret
protection and confidentiality agreements to protect our interests. We intend to
maintain several important aspects of our technology platform as trade secrets.
While we require all employees, consultants, collaborators, customers and
licensees to enter into confidentiality agreements, we cannot be certain that
proprietary information will not be disclosed or that others will not
independently develop substantially equivalent proprietary information.

RESEARCH AND DEVELOPMENT EXPENDITURES

        We have devoted our efforts primarily to research and development.
Research and development expenses were $19.8 million for the year ended December
31, 2000, $15.5 million for the year ended December 31, 1999 and $13.2 million
for the year ended December 31, 1998.

SCIENTIFIC ADVISORS

        Our principal scientific advisor:

        Sydney Brenner, M.B., D.Phil., is a distinguished Professor at the Salk
Institute of Biological Studies in La Jolla, California. From July 1996 to
January 2001, Dr. Brenner served as Director and President of The Molecular
Sciences Institute, a non-profit research institute in Berkeley, California.
Until his retirement in 1996, Dr. Brenner was Honorary Professor of Genetic
Medicine, University of Cambridge School of Clinical Medicine, Cambridge,
England. Dr. Brenner is known for his work on genetic code and the information
transfer from genes to proteins, and for his pioneering research on the genetics
and development of the nematode. Dr. Brenner is a Fellow of the Royal Society
(1995) and a Foreign Associate of the U.S. National Academy of Sciences (1977)
and has received numerous awards of recognition, including the Albert Lasker
Medical Research Award (1991), the Genetics Society of America Medal (1987) and
the Kyoto Prize (1990). Dr. Brenner is the principal inventor of Lynx's
bead-based technologies.

EMPLOYEES

        As of December 31, 2000, we employed 156 full-time employees, of which
128 were engaged in research and development activities and 28 in finance and
administrative activities. We believe we have been successful in attracting
skilled and experienced scientific personnel; however, competition for such
personnel is intense. None of our employees are covered by collective bargaining
agreements, and management considers relations with our employees to be good.

                                 BUSINESS RISKS

        Lynx's business faces significant risks. These risks include those
described below and may include additional risks of which Lynx is not currently
aware or which Lynx currently does not believe are material. If any of the
events or circumstances described in the following risks actually occurs, our
business, financial condition or results of operations could be materially
adversely affected. These risks should be read in conjunction with the other
information set forth in this report.

WE HAVE A HISTORY OF NET LOSSES. WE EXPECT TO CONTINUE TO INCUR NET LOSSES, AND
WE MAY NOT ACHIEVE OR MAINTAIN PROFITABILITY.

        We have incurred net losses each year since our inception in 1992,
including net losses of approximately $4.3 million in 1998, $6.7 million in 1999
and $13.3 million in 2000. As of June 30, 2001, we had an accumulated deficit of
approximately $76.9 million. We expect these losses to continue for at least the
next several years. The size of these net losses will depend, in part, on the
rate of growth, if any, in our revenues and on the level of our expenses. Our
research and development expenditures and general and administrative costs have
exceeded our revenues to date, and we expect research and development expenses
to increase due to planned spending for ongoing technology development and
implementation, as well as new applications. As a result, we will need to
generate significant additional revenues to achieve profitability. Even if we do
increase our revenues and achieve profitability, we may not be able to sustain
profitability.

        Our ability to generate revenues and achieve profitability depends on
many factors, including:

     -  our ability to continue existing customer relationships and enter into
        additional corporate collaborations and agreements;

     -  our ability to discover genes and targets for drug discovery;

     -  our ability to expand the scope of our research into new areas of
        pharmaceutical, biotechnology and agricultural research;

     -  our collaborators' ability to develop diagnostic and therapeutic
        products from our drug discovery targets; and

     -  the successful clinical testing, regulatory approval and
        commercialization of such products.

The time required to reach profitability is highly uncertain. We may not achieve
profitability on a sustained basis, if at all.

WE WILL NEED ADDITIONAL FUNDS IN THE FUTURE, WHICH MAY NOT BE AVAILABLE TO US.

        We have invested significant capital in our scientific and business
development activities. Our future capital requirements will be substantial as
we expand our operations, and will depend on many factors, including:

     -  the progress and scope of our collaborative and independent research and
        development projects;

     -  payments received under collaborative agreements;

     -  our ability to establish and maintain collaborative arrangements;

     -  the progress of the development and commercialization efforts under our
        collaborations and corporate agreements;


                                       10
<PAGE>   13

     -  the costs associated with obtaining access to samples and related
        information; and

     -  the costs involved in preparing, filing, prosecuting, maintaining and
        enforcing patent claims and other intellectual property rights.

        We anticipate that our current cash and cash equivalents, short-term
investments and funding to be received from collaborators and customers will
enable us to maintain our currently planned operations for at least the next 12
months. Changes to our current operating plan may require us to consume
available capital resources significantly sooner than we expect. If our capital
resources are insufficient to meet future capital requirements, we will have to
raise additional funds. We do not know if we will be able to raise sufficient
additional capital on acceptable terms, or at all. If we raise additional
capital by issuing equity or convertible debt securities, our existing
stockholders may experience substantial dilution. If we fail to obtain adequate
funds on reasonable terms, we may have to curtail operations significantly or
obtain funds by entering into financing or collaborative agreements on
unattractive terms.

OUR TECHNOLOGIES ARE NEW AND UNPROVEN AND MAY NOT ALLOW US OR OUR COLLABORATORS
TO IDENTIFY GENES OR TARGETS FOR DRUG DISCOVERY.

        You must evaluate us in light of the uncertainties and complexities
affecting an early stage genomics company. Our technologies are new and
unproven. The application of these technologies is in too early a stage to
determine whether it can be successfully implemented. These technologies assume
that information about gene expression and gene sequences may enable scientists
to better understand complex biological processes. Our technologies also depend
on the successful integration of independent technologies, each of which has its
own development risks. Relatively few therapeutic products based on gene
discoveries have been successfully developed and commercialized. Our
technologies may not enable us or our collaborators to identify genes or targets
for drug discovery. To date, neither we nor our collaborators have identified
any targets for drug discovery based on our technologies.

WE DEPEND ON OUR COLLABORATIONS AND WILL NEED TO FIND ADDITIONAL COLLABORATORS
IN THE FUTURE TO DEVELOP AND COMMERCIALIZE DIAGNOSTIC OR THERAPEUTIC PRODUCTS.

        Our strategy for the development and commercialization of our
technologies and potential products includes entering into collaborations,
subscription arrangements or licensing arrangements with pharmaceutical,
biotechnology and agricultural companies. We do not have the resources to
develop or commercialize diagnostic or therapeutic products on our own. If we
cannot negotiate additional collaborative arrangements or contracts on
acceptable terms, or at all, or such collaborations or relationships are not
successful, we may never become profitable.

        We have derived substantially all of our revenues derived from corporate
collaborations and agreements. Revenues from collaborations and related
agreements depend upon continuation of the collaborations, the achievement of
milestones and royalties derived from future products developed from our
research and technologies. To date, we have received a significant portion of
our revenues from a small number of collaborators and customers. For the three
months ended March 31, 2001, revenues from DuPont, BASF, Takara and Aventis
CropScience accounted for 36%, 25%, 19% and 10%, respectively, of our total
revenues. For the year ended December 31, 2000, revenues from DuPont, BASF and
Aventis CropScience accounted for 51%, 29% and


                                       11
<PAGE>   14


11%, respectively, of our total revenues. For the year ended December 31, 1999,
revenues from DuPont, Aventis CropScience and BASF accounted for 81%, 13% and
5%, respectively, of our total revenues. For the year ended December 31, 1998,
revenues from BASF-LYNX Bioscience AG, BASF and DuPont accounted for 61%, 33%
and 5%, respectively, of our total revenues. If we fail to successfully achieve
milestones or our collaborators fail to develop successful products, we will not
earn the revenues contemplated under such collaborative agreements. If our
collaborators or customers do no renew existing agreements, we lose one of these
collaborators or customers and we do not attract new collaborators or customers
or we are unable to enter into new collaborative agreements on commercially
acceptable terms, our revenues may decrease, and our activities may fail to lead
to commercialized products.

        Our dependence on collaborative arrangements with third parties subjects
us to a number of risks. We have limited or no control over the resources that
our collaborators may choose to devote to our joint efforts. Our collaborators
may breach or terminate their agreements with us or fail to perform their
obligations thereunder. Further, our collaborators may elect not to develop
products arising out of our collaborative arrangements or may fail to devote
sufficient resources to the development, manufacture, marketing or sale of such
products. While we do not currently compete directly with any of our
collaborators, some of our collaborators could become our competitors in the
future if they internally develop DNA or protein analysis technologies or if
they acquire other genomics or proteomics companies and move into the genomics
and proteomics industries. We will not earn the revenues contemplated under our
collaborative arrangements, if our collaborators:

-    do not develop commercially successful products using our technologies;

-    develop competing products;

-    preclude us from entering into collaborations with their competitors;

-    fail to obtain necessary regulatory approvals; or

-    terminate their agreements with us.

WE DEPEND ON A SOLE SUPPLIER TO MANUFACTURE FLOW CELLS USED IN OUR MPSS
TECHNOLOGY.

        Flow cells are glass plates that are micromachined, or fabricated to
very precise, small dimensions, to create a grooved chamber for immobilizing
microbeads in a planar microarray, which is a two-dimensional, dense ordered
array of DNA samples. We use flow cells in our Massively Parallel Signature
Sequencing, or MPSS, technology. We currently purchase the flow cells used in
our MPSS technology from a single supplier, although the flow cells are
potentially available from multiple suppliers. While we believe that alternative
suppliers for flow cells exist, identifying and qualifying new suppliers could
be an expensive and time-consuming process. Our reliance on outside vendors
involves several risks, including:

     -  the inability to obtain an adequate supply of required components due to
        manufacturing capacity constraints, a discontinuance of a product by a
        third-party manufacturer or other supply constraints;

     -  reduced control over quality and pricing of components; and

     -  delays and long lead times in receiving materials from vendors.

WE OPERATE IN AN INTENSELY COMPETITIVE INDUSTRY WITH RAPIDLY EVOLVING
TECHNOLOGIES, AND OUR COMPETITORS MAY DEVELOP PRODUCTS AND TECHNOLOGIES THAT
MAKE OURS OBSOLETE.

        The biotechnology industry is highly fragmented and is characterized by
rapid technological change. In particular, the area of genomics research is a
rapidly evolving field. Competition among entities attempting to identify genes
associated with specific diseases and to develop products based on such
discoveries is intense. Many of our competitors have substantially greater
research and product development capabilities and financial, scientific, and
marketing resources than we do.

        We face, and will continue to face, competition from pharmaceutical,
biotechnology and agricultural companies, as well as academic research
institutions, clinical reference laboratories and government agencies. Some of
our competitors, such as Affymetrix, Inc., Celera Genomics Group, Incyte
Genomics, Inc., Gene Logic, Inc., Genome Therapeutics Corporation and Hyseq,
Inc., may be:

     -  attempting to identify and patent randomly sequenced genes and gene
        fragments;

     -  pursuing a gene identification, characterization and product development
        strategy based on positional cloning, which uses disease inheritance
        patterns to isolate the genes that are linked to the transmission of
        disease from one generation to the next; and

     -  using a variety of different gene expression analysis methodologies,
        including the use of chip-based systems, to attempt to identify
        disease-related genes.

        In addition, numerous pharmaceutical, biotechnology and agricultural
companies are developing genomic research programs, either alone or in
partnership with our competitors. Our future success will depend on our ability
to maintain a competitive position with respect to technological advances. Rapid
technological development by others may make our technologies and future
products obsolete.

        Any products developed through our technologies will compete in highly
competitive markets. Our competitors may be more effective at using their
technologies to develop commercial products. Further, our competitors may obtain
intellectual property rights that would limit the use of our technologies or the
commercialization of diagnostic or therapeutic products using our technologies.
As a result, our competitors' products or technologies may render our
technologies and products, and those of our collaborators, obsolete or
noncompetitive.

IF WE FAIL TO ADEQUATELY PROTECT OUR PROPRIETARY TECHNOLOGIES, THIRD PARTIES MAY
BE ABLE TO USE OUR TECHNOLOGY, WHICH COULD PREVENT US FROM COMPETING IN THE
MARKET.

        Our success depends in part on our ability to obtain patents and
maintain adequate protection of the intellectual property related to our
technologies and products. The patent positions of biotechnology companies,
including our patent position, are generally uncertain and involve complex legal
and factual questions. We will be able to protect our proprietary rights from
unauthorized use by third parties only to the extent that our proprietary
technologies are covered by valid and enforceable patents or are effectively
maintained as trade secrets. The laws of some foreign countries do not protect
proprietary rights to the same extent as the laws of the U.S., and many
companies have encountered significant problems in protecting and defending


                                       13
<PAGE>   16

their proprietary rights in foreign jurisdictions. We have applied and will
continue to apply for patents covering our technologies, processes and products
as and when we deem appropriate. However, third parties may challenge these
applications, or these applications may fail to result in issued patents. Our
existing patents and any future patents we obtain may not be sufficiently broad
to prevent others from practicing our technologies or from developing competing
products. Furthermore, others may independently develop similar or alternative
technologies or design around our patents. In addition, our patents may be
challenged or invalidated or fail to provide us with any competitive advantage.

        We also rely on trade secret protection for our confidential and
proprietary information. However, trade secrets are difficult to protect. We
protect our proprietary information and processes, in part, with confidentiality
agreements with employees, collaborators and consultants. However, third parties
may breach these agreements, we may not have adequate remedies for any such
breach or our trade secrets may still otherwise become known by our competitors.
In addition, our competitors may independently develop substantially equivalent
proprietary information.

LITIGATION OR THIRD-PARTY CLAIMS OF INTELLECTUAL PROPERTY INFRINGEMENT COULD
REQUIRE US TO SPEND SUBSTANTIAL TIME AND MONEY AND ADVERSELY AFFECT OUR ABILITY
TO DEVELOP AND COMMERCIALIZE OUR TECHNOLOGIES AND PRODUCTS.

        Our commercial success depends in part on our ability to avoid
infringing patents and proprietary rights of third parties and not breaching any
licenses that we have entered into with regard to our technologies. Other
parties have filed, and in the future are likely to file, patent applications
covering genes, gene fragments, the analysis of gene expression and the
manufacture and use of DNA chips or microarrays, which are tiny glass or silicon
wafers on which tens of thousands of DNA molecules can be arrayed on the surface
for subsequent analysis. We intend to continue to apply for patent protection
for methods relating to gene expression and for the individual disease genes and
drug discovery targets we discover. If patents covering technologies required by
our operations are issued to others, we may have to rely on licenses from third
parties, which may not be available on commercially reasonable terms, or at all.

        Third parties may accuse us of employing their proprietary technology
without authorization. In addition, third parties may obtain patents that relate
to our technologies and claim that use of such technologies infringes these
patents. Regardless of their merit, such claims could require us to incur
substantial costs, including the diversion of management and technical
personnel, in defending ourselves against any such claims or enforcing our
patents. In the event that a successful claim of infringement is brought against
us, we may need to pay damages and obtain one or more licenses from third
parties. We may not be able to obtain these licenses at a reasonable cost, or at
all. Defense of any lawsuit or failure to obtain any of these licenses could
adversely affect our ability to develop and commercialize our technologies and
products and thus prevent us from achieving profitability.

WE HAVE LIMITED EXPERIENCE IN SALES AND MARKETING AND THUS MAY BE UNABLE TO
FURTHER COMMERCIALIZE OUR TECHNOLOGIES AND PRODUCTS.


                                       14
<PAGE>   17


        Our ability to achieve profitability depends on attracting collaborators
and customers for our technologies and products. There are a limited number of
pharmaceutical, biotechnology and agricultural companies that are potential
collaborators and customers for our technologies and products. To market our
technologies and products, we must develop a sales and marketing group with the
appropriate technical expertise. We may not successfully build such a sales
force. If our sales and marketing efforts fail to be successful, our
technologies and products may fail to gain market acceptance.

OUR SALES CYCLE IS LENGTHY, AND WE MAY SPEND CONSIDERABLE RESOURCES ON
UNSUCCESSFUL SALES EFFORTS OR MAY NOT BE ABLE TO ENTER INTO AGREEMENTS ON THE
SCHEDULE WE ANTICIPATE.

        Our ability to obtain collaborators and customers for our technologies
and products depends in significant part upon the perception that our
technologies and products can help accelerate their drug discovery and genomics
efforts. Our sales cycle is typically lengthy because we need to educate our
potential collaborators and customers and sell the benefits of our products to a
variety of constituencies within such companies. In addition, we may be required
to negotiate agreements containing terms unique to each collaborator or
customer. We may expend substantial funds and management effort with no
assurance that we will successfully sell our technologies and products. Actual
and proposed consolidations of pharmaceutical companies have negatively
affected, and may in the future negatively affect, the timing and progress of
our sales efforts.

WE MAY HAVE DIFFICULTY MANAGING OUR GROWTH.

        We expect to continue to experience significant growth in the number of
our employees and the scope of our operations. This growth may place a
significant strain on our management and operations. As our operations expand,
we expect that we will need to manage additional relationships with various
collaborators and customers, suppliers and other third parties. Our ability to
manage our operations and growth effectively requires us to continue to improve
our operational, financial and management controls, reporting systems and
procedures. We may not successfully implement improvements to our management
information and control systems in an efficient or timely manner and may
discover deficiencies in existing systems and controls.

THE LOSS OF KEY PERSONNEL OR THE INABILITY TO ATTRACT AND RETAIN ADDITIONAL
PERSONNEL COULD IMPAIR THE GROWTH OF OUR BUSINESS.

        We are highly dependent on the principal members of our management and
scientific staff. The loss of any of these persons' services might adversely
impact the achievement of our objectives and the continuation of existing
collaborations. In addition, recruiting and retaining qualified scientific
personnel to perform future research and development work will be critical to
our success. There is currently a shortage of skilled executives and employees
with technical expertise, and this shortage is likely to continue. As a result,
competition for skilled personnel is intense and turnover rates are high.
Competition for experienced scientists from numerous companies, academic and
other research institutions may limit our ability to attract and retain such
personnel. We depend on our President and Chief Executive Officer, Norman J.W.
Russell, Ph.D., the loss of whose services could have a material adverse effect
on our business. Although


                                       15
<PAGE>   18

we have an employment agreement with Dr. Russell in place, currently we do not
maintain key person insurance for him or any other key personnel.

WE USE HAZARDOUS CHEMICALS AND RADIOACTIVE AND BIOLOGICAL MATERIALS IN OUR
BUSINESS. ANY CLAIMS RELATING TO IMPROPER HANDLING, STORAGE OR DISPOSAL OF THESE
MATERIALS COULD BE TIME CONSUMING AND COSTLY.

        Our research and development processes involve the controlled use of
hazardous materials, including chemicals and radioactive and biological
materials. Our operations produce hazardous waste products. We cannot eliminate
the risk of accidental contamination or discharge and any resultant injury from
these materials. Federal, state and local laws and regulations govern the use,
manufacture, storage, handling and disposal of hazardous materials. 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. Compliance with environmental laws and
regulations may be expensive, and current or future environmental regulations
may impair our research, development and production efforts.

ETHICAL, LEGAL AND SOCIAL ISSUES MAY LIMIT THE PUBLIC ACCEPTANCE OF, AND DEMAND
FOR, OUR TECHNOLOGIES AND PRODUCTS.

        Our collaborators and customers may seek to develop diagnostic products
based on genes we discover. The prospect of broadly available gene-based
diagnostic tests raises ethical, legal and social issues regarding the
appropriate use of gene-based diagnostic testing and the resulting confidential
information. It is possible that discrimination by third-party payors, based on
the results of such testing, could lead to the increase of premiums by such
payors to prohibitive levels, outright cancellation of insurance or
unwillingness to provide coverage to individuals showing unfavorable gene
expression profiles. Similarly, employers could discriminate against employees
with gene expression profiles indicative of the potential for high
disease-related costs and lost employment time. Finally, government authorities
could, for social or other purposes, limit or prohibit the use of such tests
under certain circumstances. These ethical, legal and social concerns about
genetic testing and target identification may delay or prevent market acceptance
of our technologies and products.

        Although our technology does not depend on genetic engineering, genetic
engineering plays a prominent role in our approach to product development. The
subject of genetically modified food has received negative publicity, which has
aroused public debate. Adverse publicity has resulted in greater regulation
internationally and trade restrictions on imports of genetically altered
agricultural products. Claims that genetically engineered products are unsafe
for consumption or pose a danger to the environment may influence public
attitudes and prevent genetically engineered products from gaining public
acceptance. The commercial success of our future products may depend, in part,
on public acceptance of the use of genetically engineered products, including
drugs and plant and animal products.

IF WE DEVELOP PRODUCTS WITH OUR COLLABORATORS, AND IF PRODUCT LIABILITY LAWSUITS
ARE SUCCESSFULLY BROUGHT AGAINST US, WE COULD FACE SUBSTANTIAL LIABILITIES THAT
EXCEED OUR RESOURCES.


                                       16
<PAGE>   19


        We may be held liable, if any product we develop with our collaborators
causes injury or is otherwise found unsuitable during product testing,
manufacturing, marketing or sale. Although we have general liability and product
liability insurance, this insurance may become prohibitively expensive or may
not fully cover our potential liabilities. Inability to obtain sufficient
insurance coverage at an acceptable cost or to otherwise protect us against
potential product liability claims could prevent or inhibit our ability to
commercialize products developed with our collaborators.

HEALTHCARE REFORM AND RESTRICTIONS ON REIMBURSEMENTS MAY LIMIT OUR RETURNS ON
DIAGNOSTIC OR THERAPEUTIC PRODUCTS THAT WE MAY DEVELOP WITH OUR COLLABORATORS.

        If we successfully validate targets for drug discovery, products that we
develop with our collaborators based on those targets may include diagnostic or
therapeutic products. The ability of our collaborators to commercialize such
products may depend, in part, on the extent to which reimbursement for the cost
of these products will be available from government health administration
authorities, private health insurers and other organizations. In the U.S.,
third-party payors are increasingly challenging the price of medical products
and services. The trend towards managed healthcare in the U.S., legislative
healthcare reforms and the growth of organizations such as health maintenance
organizations that may control or significantly influence the purchase of
healthcare products and services, may result in lower prices for any products
our collaborators may develop. Significant uncertainty exists as to the
reimbursement status of newly approved healthcare products. If adequate
third-party coverage is not available in the future, our collaborators may fail
to maintain price levels sufficient to realize an appropriate return on their
investment in research and product development.

OUR FACILITIES ARE LOCATED NEAR KNOWN EARTHQUAKE FAULT ZONES; AN EARTHQUAKE OR
OTHER CATASTROPHIC DISASTER COULD CAUSE DAMAGE TO OUR FACILITIES AND EQUIPMENT,
WHICH COULD REQUIRE US TO CEASE OPERATIONS.

        Our facilities are located near known earthquake fault zones and are
vulnerable to damage from earthquakes. We are also vulnerable to damage from
other types of disasters, including fire, floods, power loss, communications
failures and similar events. If any disaster were to occur, our ability to
operate our business at our facilities would be seriously, or potentially
completely, impaired. In addition, the unique nature of our research activities
could cause significant delays in our programs and make it difficult for us to
recover from a disaster. The insurance we maintain may not be adequate to cover
our losses resulting from disasters or other business interruptions.
Accordingly, an earthquake or other disaster could materially and adversely harm
our ability to conduct business.

OUR STOCK PRICE MAY BE EXTREMELY VOLATILE.

        We believe that the market price of our common stock will remain highly
volatile and may fluctuate significantly due to a number of factors. The market
prices for securities of many publicly-held, early-stage biotechnology companies
have in the past been, and can in the future be expected to be, especially
volatile. For example, during the two-year period from June 30, 1999 to 2001,
the closing sales price of our common stock as quoted on the Nasdaq National
Market fluctuated from a low of $5.01 to a high of $96.875 per share. In
addition, the securities


                                       17
<PAGE>   20

markets have from time to time experienced significant price and volume
fluctuations that may be unrelated to the operating performance of particular
companies. The following factors and events may have a significant and adverse
impact on the market price of our common stock:

     -  fluctuations in our operating results;

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

     -  release of reports by securities analysts;

     -  developments or disputes concerning patent or proprietary rights;

     -  developments in our relationships with current or future collaborators
        or customers; and

     -  general market conditions.

Many of these factors are beyond our control. These factors may cause a decrease
in the market price of our common stock, regardless of our operating
performance.

ANTI-TAKEOVER PROVISIONS IN OUR CHARTER DOCUMENTS AND UNDER DELAWARE LAW MAY
MAKE IT MORE DIFFICULT TO ACQUIRE US OR TO EFFECT A CHANGE IN OUR MANAGEMENT,
EVEN THOUGH AN ACQUISITION OR MANAGEMENT CHANGE MAY BE BENEFICIAL TO OUR
STOCKHOLDERS.

        Under our certificate of incorporation, our board of directors has the
authority, without further action by the holders of our common stock, to issue
2,000,000 additional shares of preferred stock from time to time in series and
with preferences and rights as it may designate. These preferences and rights
may be superior to those of the holders of our common stock. For example, the
holders of preferred stock may be given a preference in payment upon our
liquidation or for the payment or accumulation of dividends before any
distributions are made to the holders of common stock.

        Although we have no present intention to authorize or issue any
additional series of preferred stock, any authorization or issuance, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could also have the effect of making it more difficult
for a third party to acquire a majority of our outstanding voting stock or
making it more difficult to remove directors and effect a change in management.
The preferred stock may have other rights, including economic rights senior to
those of our common stock, and, as a result, an issuance of additional preferred
stock could lower the market value of our common stock. Provisions of Delaware
law may also discourage, delay or prevent someone from acquiring or merging with
us.

RECENT PRONOUNCEMENTS COULD IMPACT OUR FINANCIAL POSITION AND RESULTS OF
OPERATIONS.

        In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standard No. 133, "Accounting for Derivative Instruments
and Hedging Activities", which is effective for the year ending December 31,
2001. This statement establishes accounting and reporting standards requiring
that every derivative instrument, including certain derivative instruments
embedded in other contracts, be recorded in the balance sheet as either an asset
or liability measured at its fair value. The statement also requires that
changes in the derivative's


                                       18
<PAGE>   21


fair value be recognized in earnings unless specific hedge accounting criteria
are met. We believe the adoption of SFAS 133 on January 1, 2001 had no material
effect on the financial statements, since we currently do not invest in
derivative instruments and engage in hedging activities.



                                       19
<PAGE>   22
ITEM 2. PROPERTIES

        In February 1998, we entered into a noncancelable operating lease for
facilities space of approximately 111,000 square-feet in two buildings in
Hayward, California. Currently, our corporate headquarters, principal research
and development facilities and production facilities are located in one of the
two buildings. The remaining space will be developed and occupied in phases,
depending on our growth. The lease runs through December 2008. We have an option
to extend the lease for an additional five-year period, subject to certain
conditions. We have leased approximately 37,000 square feet of additional space
in one of the buildings for further expansion purposes.

        In June 1998, Lynx GmbH entered into a noncancelable operating lease for
facilities space of approximately 6,300 square-feet in Heidelberg, Germany, to
house its operations. The space will be developed and occupied in phases,
depending on the growth of the organization. The lease terminates in June 2005.
A portion of this space is currently being subleased by BASF-LYNX.

        In August 1993, we entered into a noncancelable operating lease for
another facility that expires on July 31, 2003. In 1998, we entered into an
agreement to sublease a portion of this space, and in 1999, through a subsequent
agreement, subleased the remaining portion of the facility. The term of the
sublease runs through July 2003. Rent from the sublease is sufficient to cover
the rent and other operating expenses incurred by Lynx under the terms of the
1993 lease.

ITEM 3. LEGAL PROCEEDINGS

        We are not a party to any material legal proceedings.

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

        No matters were submitted to a vote of security holders in the quarter
ended December 31, 2000.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

        On December 30, 1997, we listed our common stock on the Nasdaq National
Market. Prior to December 30, 1997, there was no established public trading
market for our voting stock. Our common stock trades on the Nasdaq National
Market under the symbol LYNX. The following table sets forth, for the periods
indicated, the high and low closing sale prices for our common stock as reported
by the Nasdaq National Market:

        As of March 22, 2001, there were approximately 2,400 stockholders of
record of our common stock. On March 22, 2001, the last reported sale price of
our common stock was $7.50.

        We have never declared or paid any cash dividends on our common stock.
We currently intend to retain earnings to support the development of our
business and do not anticipate paying cash dividends for the foreseeable future.
Any future determination to pay dividends will be at the discretion of our board
of directors.

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

        The following information is dated as of March 30, 2001, the initial
filing dated of this Annual Report, except for "Liquidity and Capital
Resources," which has been amended and restated as of the date of this Form
10-K/A filing. Investors are directed to our review our additional SEC reports
and filings, including our Quarterly Reports on Form 10-Q, for additional
information.

        Except for the historical information contained herein, the following
discussion contains forward-looking statements that involve risks and
uncertainties. When used herein, the words "believe," "anticipate," "expect,"
"estimate" and similar expressions are intended to identify such forward-looking
statements. There can be no assurance that these statements will prove to be
correct. The Lynx's actual results could differ materially from those discussed
here. Factors that could cause or contribute to such differences include, but
are not limited to, those discussed in this section as well as in the section
entitled "Item 1. Business -- Business Risks." Lynx undertakes no obligation to
update any of the forward-looking statements contained herein to reflect any
future events or developments.

OVERVIEW

        We are a leader in the development and application of novel technologies
for the discovery of gene expression patterns and genomic variations important
to the pharmaceutical, biotechnology and agricultural industries. These
technologies are based on Megaclone, our unique and proprietary cloning
procedure. Megaclone transforms a sample containing millions of DNA molecules
into one made up of millions of micro-beads, each of which carries approximately
100,000 copies of one of the DNA molecules in the sample. Based on Megaclone, we
have developed a suite of applications that have the potential to enhance the
pace, scale and quality of genomics and genetics research programs. Currently,
our principal collaborators and customers are BASF AG, E.I. DuPont de Nemours
and Company, Aventis CropScience GmbH, Oxagen Limited Hybrigenics S.A., Genomics
Collaborative Inc., Molecular Engines Laboratories SA, the Institute of
Molecular and Cell Biology, Phytera, Inc. and Celera Genomics. Additionally, we
have provided a license for the use of certain of our technologies to Takara
Shuzo Co. Ltd.

        We have incurred net losses each year since our inception in 1992. As of
December 31, 2000, we had an accumulated deficit of approximately $66.7 million.
We expect these losses to continue for at least the next several years. The size
of these losses will depend, in part, on the rate of growth, if any, in our
revenues and on the level of our expenses.

        Revenues from technology access fees are generally from upfront payments
from our collaborators, customers and licensees who are provided access to our
technologies for specified periods. We receive service fees from our
collaborators and customers for genomics discovery services performed by us on
the biological samples they send to us. Collaborative research revenues are
payments received under various agreements and include such items as milestone
payments. Other revenues include the proceeds from the sale of our technology
assets to BASF-LYNX and product sales under one of our former programs.

        Technology access fees are deferred and recognized as revenue on a
straight-line basis over the noncancelable term of the agreement to which they
relate. Payments for services and/or materials provided by us are recognized as
revenues when earned over the period in which the services are performed and/or
materials are delivered, provided no other obligations, refunds or credits to be
applied to future work exist. Milestone payments are recognized as revenues upon
the achievement of the related milestone and the satisfaction of any related
obligations. Revenues from the sales of products, which have been immaterial to
date, are recognized upon shipment to the customer.

        To date, we have received, and expect to continue to receive in the
future, a significant portion of our revenues from a small number of
collaborators and customers. During 2000, revenues from 3 collaborators and
customers accounted for 51%, 29% and 11% of total revenues. During 1999,
revenues from 3 collaborators and customers accounted for 81%, 13% and 5% of
total revenues. During 1998, revenues from 3 collaborators and customers
accounted for 61%, 33% and 5% of total revenues.

        Revenues in each quarterly and annual period have in the past, and could
in the future, fluctuate due to: the timing and amount of any technology access
fee and the period over which the revenue is recognized; the level of service
fees, which is tied to the number and timing of biological samples received from
our collaborators and customers, as well as our performance of the related
genomics discovery services on the samples; the timing of achievement of
milestones and the amount of related payments to us; and the number, type and
timing of new, and the termination of existing, agreements with collaborators
and customers.

        Cost of services fees includes the costs of direct labor, materials and
supplies, outside expenses, equipment and overhead incurred by us in performing
our genomics discovery services for our collaborators and customers. Research
and development expenses include the costs of personnel, materials and supplies,
outside expenses, equipment and overhead incurred by us in our technology and
application development efforts. We expect research and development expenses to
increase substantially due to planned spending for ongoing technology
development and implementation, as well as new applications. General and
administrative expenses include the costs of personnel, materials and supplies,
outside expenses, equipment and overhead incurred by us primarily in our
administrative,
                                       23


<PAGE>   26
business development, legal and investor relations activities. We expect general
and administrative expenses to increase in support of our research and
development, commercial and business development efforts.

        We account for our investment in BASF-LYNX on the equity method, however
such investment has a carrying value of zero in the financial statements. As we
have no obligation to fund the operations of BASF-LYNX, we have not recognized
our share of BASF-LYNX's losses in the accompanying statements of operations.

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 2000 AND 1999

Revenues

        We had total revenues of $12.6 million for the year ended December 31,
2000, compared to $12.9 million for the year ended December 31, 1999. Revenues
for 2000 included technology access fees and service fees of $12.4 million and
collaborative research and other revenue of $0.2 million. Revenues for 1999
included technology access and service fees of $7.8 million and collaborative
research revenue from a $5.0 million milestone fee.

Operating Costs and Expenses

        Our total operating costs and expenses were $29.6 million for the year
ended December 31, 2000, compared to $20.5 million for the year ended December
31, 1999. Cost of services fees were $3.7 million for the year ended December
31, 2000, compared to $0.8 million for the year ended December 31, 1999, and
reflect the costs of providing our genomics discovery services. Research and
development expenses were $19.8 million in 2000 and $15.5 million in 1999. The
increase in research and development expenses in 2000, as compared to 1999, is
due primarily to higher personnel-related and facilities expenses and an
increase in materials consumed in research and development efforts. Our efforts
in 2000 were directed toward the expansion of the commercial applications of our
genomics technologies. These activities included new collaborations and other
agreements, internal discovery projects and an internal investment in building a
store of human genomic information. We also continued our development work on
our Megatype and Protein ProFiler technologies. We expect research and
development expenses to continue to increase due to planned spending for ongoing
technology development and implementation, as well as new applications.

        General and administrative expenses were $6.2 million for the year ended
December 31, 2000, compared to $4.2 million for the year ended December 31,
1999. The increase was primarily due to higher personnel-related expenses and
increased costs for outside services. We expect general and administrative
expenses to increase in support of our research and development, commercial and
business development efforts.

Interest and Other Income

        Net interest income decreased to $0.9 million in the year ended December
31, 2000, from $1.1 million in the year ended December 31, 1999, primarily due
to lower average cash, cash equivalents and investment balances during 2000, as
compared to 1999, and increased interest expense incurred on equipment-related
debt outstanding in 2000. Other income was $3.3 million in the year ended
December 31, 2000, and $0.1 million in the year ended December 31, 1999. In
2000, other income was due primarily to a gain of approximately $3.1 million
from the receipt of shares of common stock from Inex Pharmaceuticals
Corporation, as part of the proceeds related to the March 1998 sale of our
former antisense program. In 1999, other income was attributable to a gain on
the sale of certain fixed assets no longer used in our operations.

Income Taxes

        The provision for income taxes of approximately $500,000 for 2000
consisted entirely of foreign withholding tax due on a payment received from one
of our customers, collaborators and licensees. The provision for income taxes of
approximately $258,000 for 1999 consisted entirely of alternative minimum tax.

        As of December 31, 2000, we had a federal net operating loss
carryforward of approximately $38.6 million, which will expire at various dates
from 2008 through 2020, if not utilized. We have a state net operating loss
carryforward of approximately $5.3 million, which will expire in 2010.


                                       24


<PAGE>   27
        As of December 31, 2000, we also had federal and California research and
development and other tax credit carryforwards of approximately $3.8 million and
$1.3 million, respectively. The federal research and development credit will
expire at various dates from 2008 through 2020, if not utilized.

        Utilization of net operating loss and tax credit carryforwards may be
subject to a substantial annual limitation due to the ownership change
limitations provided by the Internal Revenue Code of 1986, as amended, and
similar state provisions. The annual limitation may result in expiration of net
operating loss and tax credit carryforwards before full utilization. Utilization
of federal and California net operating losses and credit carryforwards incurred
prior to February 1994 is limited on an annual basis under the Internal Revenue
Code of 1986, as amended, as a result of an ownership change in 1994.

YEARS ENDED DECEMBER 31, 1999 AND 1998

Revenues

        We had total revenues of $12.9 million for the year ended December 31,
1999, compared to $7.0 million for the year ended December 31, 1998. Revenues
for 1999 included technology access fees and service fees of $7.8 million and
collaborative research revenue from a $5.0 million milestone fee. Revenues for
1998 included technology access fees of $2.6 million and $4.3 million from the
sale of our technology assets for certain central nervous system, or CNS,
disorders.

Operating Costs and Expenses

        Our total operating costs and expenses were $20.5 million for the year
ended December 31, 1999, compared to $15.3 million for the year ended December
31, 1998. Cost of services fees were $0.8 million in 1999 and reflect the costs
of providing our genomics discovery services, which commenced in 1999. Research
and development expenses were $15.5 million in 1999 and $13.2 million in 1998.
The increase in research and development expenses in 1999, as compared to 1998,
is due primarily to a higher number of personnel, facilities expansion and
activities as we prepared to launch our commercial operations. Our efforts in
1999 focused on initiating production for the commercial application of our
genomics technologies and completing the scientific experimentation that led to
the successful achievement of technology milestones and achievements under
certain of our agreements. We expect research and development expenses to
continue to increase substantially due to planned spending for ongoing
technology development and implementation, as well as new applications.

        General and administrative expenses were $4.2 million for the year ended
December 31, 1999, compared to $2.1 million for the year ended December 31,
1998. The increase was primarily due to higher personnel-related expenses,
outside services costs and facilities expansion. We expect general and
administrative expenses to increase in support of our research and development,
commercial and business development efforts.

Interest and Other Income

        Net interest income decreased to $1.1 million in the year ended December
31, 1999, from $1.2 million in the year ended December 31, 1998, primarily due
to lower average cash, cash equivalents and investment balances during 1999, as
compared to 1998, and interest expense incurred on equipment-related debt
outstanding in 1999. Other income was $0.1 million in the year ended December
31, 1999, and $2.9 million in the year ended December 31, 1998. In 1998, other
income was due primarily to the gain from the sale of the assets associated with
our antisense program to Inex Pharmaceuticals Corporation.

Income Taxes

        The provision for income taxes of approximately $258,000 for 1999 and
$151,000 for 1998 consisted entirely of alternative minimum tax.

LIQUIDITY AND CAPITAL RESOURCES

        Net cash used in operating activities was $9.0 million for the year
ended December 31, 2000, as compared to net cash provided by operating
activities of $7.8 million for the same period in 1999. This change was
primarily due to the change in deferred revenue and a higher net loss in 2000,
offset partially by the change in accounts payable and accrued liabilities, the
difference in depreciation and amortization of fixed assets and leasehold
improvements and the change in accounts receivable. The amount of net cash used
in operating activities differed from the 2000 net loss due primarily to the
depreciation and amortization of fixed assets and leasehold


                                       25


<PAGE>   28
improvements and the collection of accounts receivable. The 1999 net cash
provided by operating activities differed from the 1999 net loss due primarily
to an increase in deferred revenue and collection of accounts receivable,
partially offset by a decrease in current liabilities. Net cash provided by
operating activities of $5.7 million for the year ended December 31, 1998, was
primarily due to increases in deferred revenue, accounts payable and accrued
liabilities, partially offset by an increase in accounts receivable.

        Net cash used in investing activities of $2.3 million for the year ended
December 31, 2000, was due primarily to expenditures for leasehold improvements
and purchases of equipment, partially offset by net maturities of short-term
investments. Net cash used in investing activities of $10.7 million for the year
ended December 31, 1999, was primarily due to net purchases of short-term
investments and leasehold improvements and equipment purchases. Net cash
provided by investing activities of $1.0 million for the year ended December 31,
1998, was primarily due to net maturities of short-term investments, offset in
part by expenditures for leasehold improvements and purchases of equipment.

        Net cash provided by financing activities in 2000 of $1.1 million was
due primarily to issuance of common stock from the exercise of employee stock
options. Net cash provided by financing activities in 1999 of $4.8 million
resulted primarily from borrowings under an equipment loan arrangement. Net cash
provided by financing activities of $0.6 million in the year ended December 31,
1998 resulted from the issuance of common stock. Cash and cash equivalents and
short-term investments were $18.8 million at December 31, 2000.

        Net cash used in operating activities was $10.8 million for the
six-month period ended June 30, 2001, as compared to net cash used in operating
activities of $5.5 million for the same period in 2000. This change was
primarily due to a higher net loss in the 2001 period, the change in accounts
payable and the change in deferred revenues, partially offset by the difference
between the 2001 loss and the 2000 gain related to the common stock of Inex
received from the sale of Lynx's antisense program to Inex, and higher
depreciation and amortization expense for fixed assets and leasehold
improvements. Net cash used in operating activities of $10.8 million for the
six-month period in 2001 differed from the net loss for the same period in 2000
primarily due to the decrease in deferred revenues, offset partially by
depreciation and amortization expense.

        Net cash provided by investing activities of $1.7 million for the
six-month period ended June 30, 2001 related primarily to the net maturities of
short-term investments, offset partially by expenditures for capital assets. Net
cash provided by financing activities of $10.5 million for the six-month period
ended June 30, 2001 related primarily to the issuance of common stock pursuant
to a common stock purchase agreement between Lynx and certain investors,
partially offset by repayment of principal under an equipment loan arrangement.
Cash, cash equivalents, short-term investments and marketable securities were
$15.8 million at June 30, 2001.

        In May 2001, we completed a private placement of common stock and
warrants to purchase common stock. The financing included the sale of 1,747,248
newly issued shares of common stock at a purchase price of $6.37 per share
resulting in net proceeds of approximately $10.5 million, pursuant to a common
stock purchase agreement between Lynx and certain investors. In connection with
this transaction, we issued warrants to purchase up to 436,808 shares of common
stock at an exercise price of $9.2011 per share. We have filed with the
Securities and Exchange Commission a resale registration statement related to
the privately placed securities. We expect to use the net proceeds from the
financing to support ongoing commercial, business development and research and
development activities. Our research and development efforts will focus on the
continuing development of the Megatype and Protein ProFiler technologies, as
well as internal discovery projects.

        In late 1998, we entered into a financing agreement with a financial
institution, Transamerica Business Credit Corporation, under which we drew down
$4.8 million during 1999 for the purchase of equipment and certain other capital
expenditures. We granted the lender a security interest in all items financed by
it under this agreement. Each draw down under the loan has a term of 48 months
from the date of the draw down. As of June 30, 2001, the principal balance under
loans outstanding under this agreement was approximately $3.8 million. The draw
down period under the agreement expired on March 31, 2000.

        We plan to use available funds for ongoing commercial and research and
development activities, working capital and other general corporate purposes and
capital expenditures. We expect capital investments during 2001 will be
comprised primarily of equipment purchases required in the normal course of
business and expenditures for leasehold improvements. We intend to invest our
excess cash in investment-grade, interest-bearing securities.

        We have obtained funding for our operations primarily through sales of
preferred and common stock to venture capital investors, institutional investors
and collaborators, payments under contractual arrangements with customers,
collaborators and licensees and interest income. The cost, timing and amount of
funds required for specific uses by us cannot be precisely determined at this
time and will be based upon the progress and the scope of our collaborative and
independent research and development projects; payments received under customer,
collaborative and license agreements; our ability to establish and maintain
customer, collaborative and license agreements; costs of protecting intellectual
property rights; legal and administrative costs; additional facilities capacity
needs and the availability of alternate methods of financing.

        We expect to incur substantial and increasing research and development
expenses and intend to seek additional financing, as needed, through
arrangements with customers, collaborators and licensees and equity or debt
offerings. We cannot assure you that any additional financing we require will be
available on favorable terms, or at all. We believe, at current spending levels,
our existing capital resources and interest income thereon, will enable us to
maintain our current and planned operations through at least the next 12 months.

RECENT ACCOUNTING PRONOUNCEMENTS

        In June 1998, the Financial Accounting Standards Board, or "FASB,"
issued Statement of Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and Hedging Activities." SFAS 133 requires us to
recognize all derivatives on the balance sheet at fair value. Derivatives that
are not hedges must be adjusted to fair value through net income. If the
derivative is a hedge, depending on the nature of the hedge, changes in the fair
value of the derivative are either offset against the change in fair value of
assets, liabilities or firm commitments through earnings or recognized in the
other comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of the derivative's change in fair value will be immediately
recognized in earnings. SFAS 133 is effective for our year ending December 31,
2001. We do not currently hold any derivatives and we do not expect this
pronouncement to materially impact results of operations.

        In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements," which must be adopted in the
fourth quarter of 2000. SAB 101 summarizes certain areas of the Staff's views in
applying generally accepted accounting principles to revenue in financial
statements and specifically addresses revenue recognition for non-refundable
technology access fees. We believe that our revenue recognition policies prior
to adoption of SAB 101 complied with the requirements of SAB 101.

        In March 2000, the FASB issued Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation", which contains rules
designed to clarify the application of APB Opinion No. 25. FIN 44 was effective
on July 1, 2000 and adopted by us at that time. The adoption of FIN 44 did not
have a material impact on our operating results or financial position.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Short-Term Investments

        The primary objective of our investment activities is to preserve
principal while, at the same time, maximizing yields without significantly
increasing risk. To achieve this objective, we invest in highly liquid and
high-quality debt securities. Our investments in debt securities are subject to
interest rate risk. To minimize the exposure due to adverse shifts in interest
rates, we invest in short-term securities and maintain an average maturity of
less than one year. As a result, we do not believe we are subject to significant
interest rate risk.

        The Company holds an investment in an equity security that is subject to
market volatility. The fair value of the equity security recorded at December
31, 2000 and 1999 was $2.6 million and $1.8 million, respectively.

Foreign Currency Rate Fluctuations

        The functional currency for our German subsidiary is the deutsche mark.
Our German subsidiary's accounts are translated from the German deutsche mark to
the U.S. dollar using the current exchange rate in effect at the balance sheet
date, for balance sheet accounts, and using the average exchange rate during the
period, for revenues and expense accounts. The effects of translation are
recorded as a separate component of stockholders' equity, and to date, have not
been material. Our German subsidiary conducts its business in local European
currencies. Exchange gains and losses arising from these transactions are
recorded using the actual exchange differences on the date of the transaction.
We have not taken any action to reduce our exposure to changes in foreign
currency exchange rates, such as options or futures contracts, with respect to
transactions with our German subsidiary or transactions with our European
collaborators and customers.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Lynx Therapeutics

        We have audited the accompanying consolidated balance sheets of Lynx
Therapeutics, Inc. as of December 31, 2000 and 1999, and the related statements
of operations, stockholders' equity and cash flows for each of the three years
in the period ended December 31, 2000. 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 in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

        In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Lynx Therapeutics,
Inc. at December 31, 2000 and 1999, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 2000, in
conformity with accounting principles generally accepted in the United States.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

BUSINESS AND BASIS OF PRESENTATION

        Lynx Therapeutics, Inc. ("Lynx" or the "Company") is a leader in the
development and application of novel technologies for the discovery of gene
expression patterns and genomic variations important to the pharmaceutical,
biotechnology and agricultural industries. These technologies are based on
Megaclone, Lynx's unique and proprietary cloning procedure. Megaclone transforms
a sample containing millions of DNA molecules into one made up of millions of
micro-beads, each of which carries approximately 100,000 copies of one of the
DNA molecules in the sample. Based on Megaclone, Lynx has developed a suite of
applications that have the potential to enhance the pace, scale and quality of
genomics and genetics research programs. Currently, Lynx's principal
collaborators and customers are BASF AG, E.I. DuPont de Nemours and Company,
Aventis CropScience GmbH, Oxagen Limited Hybrigenics S.A., Genomics
Collaborative Inc., Molecular Engines Laboratories SA, the Institute of
Molecular and Cell Biology, Phytera, Inc. and Celera Genomics. Additionally,
Lynx has provided a license for the use of certain of its technologies to Takara
Shuzo Co. Ltd.

        The Company's consolidated financial statements have been presented on a
basis that contemplates the realization of assets and satisfaction of
liabilities in the normal course of business. The Company has experienced
operating losses since its inception of $66.7 million, including a net loss of
$13.3 million in the year ended December 31, 2000, and expects such losses to
continue as it proceeds with the development and commercialization of its
technology. The Company's cash, cash equivalents and short-term investments were
$18.8 million at December 31, 2000. Management believes that its current capital
resources along with cash to be generated from its existing collaboration
arrangements will be sufficient to enable the Company to meet its projected
operating and capital requirements through December 31, 2001. Additionally, Lynx
intends to seek additional financing, as needed, through arrangements with
customers, collaborators and licensees and equity or debt offerings. There can
be no assurance that additional financing, if required, will be available on
satisfactory terms or at all. If the Company is unable to secure additional
financing, management may need to reevaluate and revise its current operating
plans as well as reduce its anticipated level of expenditures.

        The consolidated financial statements of the Company include the
accounts of the Company and its wholly-owned subsidiary, Lynx Therapeutics GmbH,
formed under the laws of the Federal Republic of Germany. All significant
intercompany balances and transactions have been eliminated. Certain amounts in
prior periods have been reclassified to conform to the current year
presentation.

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 amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

        The Company considers all investments in money market mutual funds,
commercial paper and corporate bonds and notes with original maturities from the
date of purchase of 90 days or less as cash equivalents. Investments with
original maturities beyond 90 days are considered to be short-term investments.
Equity securities are considered to be short-term investments. The Company's
investment policy stipulates that the investment portfolio be maintained with
the objectives of preserving principal, maintaining liquidity and maximizing
return.

        The Company determines the appropriate classification of money market
mutual funds, commercial paper and corporate bonds and notes at the time of
purchase and reevaluates such designation as of each balance sheet date. As of
December 31, 2000 and 1999, the Company has classified its entire investment
portfolio as available-for-sale. Available-for-sale securities are carried at
fair value based on quoted market prices, with the unrealized gains and losses
reported as a separate component of stockholders' equity. The cost of
investments in this category is adjusted for amortization of premiums and
accretion of discounts to maturity, which are included in interest income.
Realized gains and losses and declines in value judged to be
other-than-temporary, on available-for-sale securities, if any, are included in
interest income or expense. The cost of securities sold, if any, is based on the
specific identification method.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION
(CONTINUED)

        The Company invests its excess cash in deposits with major banks and in
money market and short-term debt securities of companies with strong credit
ratings from a variety of industries. These securities generally mature within
365 days and, therefore, bear minimal interest-rate risk. The Company, by
corporate policy, limits the amount of credit exposure to any one issuer and to
any one type of investment.

PROPERTY AND EQUIPMENT

        Property and equipment are stated at original cost and are depreciated
using the straight-line method over the estimated useful lives of the assets,
which is generally three years. Leasehold improvements are amortized over the
lesser of the useful life of the asset or the remaining term of the facility
lease.

REVENUE RECOGNITION

        Revenues from technology access fees have generally resulted from
upfront payments from collaborators, customers and licensees who are provided
access to Lynx's technologies for specified periods. The Company receives
service fees from collaborators and customers for genomics discovery services
performed by Lynx on the biological samples they send to Lynx. Collaborative
research revenues are payments received under various agreements and include
such items as milestone payments. Milestone payments are recognized pursuant to
collaborative agreements upon the achievement of specified technology
developments, representing the culmination of the earnings process, for
financial accounting purposes. Other revenues include non-contract related
revenues, such as the proceeds from the sale of technology assets to BASF-LYNX
and product sales under one of Lynx's former programs.

        Technology access fees are deferred and recognized as revenue on a
straight-line basis over the noncancelable term of the agreement to which they
relate. Payments for services and/or materials provided by Lynx are recognized
as revenues when earned over the period in which the services are performed
and/or materials are delivered, provided no other obligations, refunds or
credits to be applied to future work exist. Milestone payments are recognized as
revenue upon the achievement of the related milestone and the satisfaction of
any related obligations. Revenues from the sales of products, which have been
immaterial to date, are recognized upon shipment to the customer.

        During 2000, revenue from 3 collaborators and customers represented 51%,
29% and 11% of total revenues. During 1999, revenue from 3 collaborators and
customers represented 81%, 13% and 5% of total revenues. During 1998, revenue
from three collaborators and customers represented 61%, 33% and 5% of total
revenues.

NET LOSS PER SHARE

        Basic earnings per share ("EPS") is computed by dividing income or loss
applicable to common stockholders by the weighted-average number of common
shares outstanding for the period, net of certain common shares outstanding
which are subject to continued vesting and the Company's right of repurchase.
Diluted EPS reflects the potential dilution of securities that could share in
the earnings of the Company, to the extent such securities are dilutive. Basic
and diluted net loss per share is equivalent for all periods presented herein
due to the Company's net loss in all periods. At December 31, 2000, options to
purchase approximately 2,457,000 shares of common stock at a weighted-average
price of $13.16 per share have been excluded from the calculation of diluted
loss per share for 2000 because the effect of inclusion would be antidilutive.
The options will be included in the calculation at such time as the effect is no
longer antidilutive, as calculated using the treasury stock method. The
weighted-average number of shares subject to repurchase for fiscal years 2000,
1999 and 1998 were 16,000, 55,000 and 152,000, respectively. The common shares
which are outstanding but are subject to the Company's right of repurchase,
which expires ratably over five years, have been excluded from the calculation
of basic loss per share. The repurchasable shares will be included in the
calculation of basic EPS at such time as the Company's right of repurchase
lapses.

        See Note 7 for additional disclosure regarding common stock and stock
options.

STOCK-BASED COMPENSATION

        The Company grants stock options for a fixed number of shares to
employees with an exercise price equal to the fair value of the shares at the
date of grant. The Company accounts for stock option grants in accordance with
APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and
related Interpretations. Under APB 25, because the exercise price of the
Company's employee stock options equals the market price of the underlying stock
on the date of grant, no compensation expense is recognized.

        All stock option awards to non-employees are accounted for at the fair
value of the consideration received or the fair value of the equity instrument
issued, as calculated using the Black-Scholes model, in accordance with FAS 123
and Emerging Issues Task Force Consensus No. 96-18, "Accounting for Equity
Instruments that are Issued to Other Than Employees for Acquiring, or in
Conjunction with Selling, Goods or Services." The option arrangements are
subject to periodic remeasurement over their vesting terms. The Company recorded
compensation expense related to option grants to non-employees of $114,000 for
the year ended December 31, 2000, $87,000 for the year ended December 31, 1999
and $111,000 for the year ended December 31, 1998.

SEGMENT REPORTING

        Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" ("SFAS 131"), establishes
standards for the way that public business enterprises report information about
operating segments in financial statements. SFAS 131 also establishes standards
for related disclosures about products and services, geographic areas and major
customers. The Company's business activities include the development of
technologies aimed at handling and/or analyzing the DNA molecules or fragments
in biological samples. Accordingly, the Company operates in only one business
segment. All of the Company's assets and revenues are derived from this
activity. Substantially all of the Company's assets are located in the United
States. To date, revenues have been derived primarily from contracts with
companies located in North America, Europe and Asia, as follows (revenue is
attributed to geographic areas based on the location of the customers):

INCOME TAXES

        Under Statement of Financial Accounting Standards No. 109, "Accounting
for Income Taxes" ("SFAS 109"), deferred tax assets and liabilities are
determined based on the difference between financial reporting and tax bases of
assets and liabilities, and are measured using the enacted tax rates and laws
that will be in effect when the differences are expected to reverse. SFAS 109
provides for the recognition of deferred tax assets if realization of such
assets is more likely than not. Based upon the weight of available evidence,
which includes the Company's historical operating performance and the reported
cumulative net losses for the prior three years, the Company has provided a full
valuation against its net deferred tax assets as of December 31, 2000 and 1999.
The Company intends to evaluate the realizability of the deferred tax assets on
a quarterly basis. See Note 8 to the Consolidated Financial Statements.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the Financial Accounting Standards Board (the "FASB") issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS 133"). SFAS 133 requires Lynx to
recognize all derivatives on the balance sheet at fair value. Derivatives that
are not hedges must be adjusted to fair value through net income. If the
derivative is a hedge, depending on the nature of the hedge, changes in the fair
value of the derivative are either offset against the change in fair value of
assets, liabilities or firm commitments through earnings or recognized in the
other comprehensive income until the hedged item is recognized in earnings. The
ineffective portion of the derivative's change in fair value will be immediately
recognized in

earnings. SFAS 133 is effective for Lynx's year ending December 31, 2001. Lynx
does not currently hold any derivatives and does not expect this pronouncement
to materially impact results of operations.

        In December 1999, the SEC issued Staff Accounting Bulletin No. 101,
"Revenue Recognition in Financial Statements," which must be adopted in the
fourth quarter of 2000. SAB 101 summarizes certain areas of the Staff's views in
applying generally accepted accounting principles to revenue in financial
statements and specifically addresses revenue recognition for non-refundable
technology access fees. Lynx believes that its revenue recognition policies
prior to adoption of SAB 101 complied with the requirements of SAB 101.

        In March 2000, the FASB issued Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation", which contains rules
designed to clarify the application of APB Opinion No. 25. FIN 44 was effective
on July 1, 2000 and adopted by Lynx at that time. The adoption of FIN 44 did not
have a material impact on Lynx's operating results or financial position.

        During the years ended December 31, 2000, 1999 and 1998, the Company did
not sell any equity securities. As of December 31, 2000, $7.0 million of the
marketable securities were classified as cash equivalents and $10.9 million were
classified as short-term investments. As of December 31, 1999, $16.1 million of
the marketable securities were classified as cash equivalents, $12.7 million
were classified as short-term investments and $1.8 million were classified as
other non-current assets. All short-term investments have maturities of less
than one year. Expected maturities may differ from contractual maturities
because the issuers of the securities may have the right to prepay obligations
without prepayment penalties.

        BASF-LYNX

        In 1996, Lynx and BASF established  BASF-LYNX, a joint venture company
in Heidelberg, Germany. BASF-LYNX began operations in 1997 and is employing
Lynx's technologies in its neuroscience, toxicology and microbiology research
programs. Upon the establishment of BASF-LYNX, Lynx contributed access to its
technologies to BASF-LYNX in exchange for an initial 49% equity ownership. BASF,
by committing to provide research funding to BASF-LYNX of DM50 million (or
approximately $23.4 million based on a August 2001 exchange rate) over a
five-year period beginning in 1997, received an initial 51% equity ownership in
BASF-LYNX. In 1998, BASF agreed to provide an additional $10 million in research
funding to BASF-LYNX, of which $4.3 million was paid to Lynx for technology
assets related to a CNS program. In June 2001, Lynx extended its technology
licensing agreement with BASF-LYNX (see Note 12).

4. SALE OF THE ANTISENSE BUSINESS

        In March 1998, Lynx sold its portfolio of phosphorothioate antisense
patents and licenses and its therapeutic oligonucleotide manufacturing facility
(collectively, the "Antisense Business") to Inex Pharmaceuticals Corporation
("Inex"), a Canadian company. As partial consideration in this transaction, Lynx
received $3 million in cash and will receive 1.2 million shares of Inex common
stock, in three equal installments, with the first 400,000 shares received in
March 1998, and the second 400,000 shares received in March 2000. The third
installment of stock is to be received in March 2001. The Inex common stock
received by Lynx is subject to certain restrictions on trading for specific
periods of time following receipt by Lynx, with the sale restriction on the
initial 400,000 shares and second installment of 400,000 shares having expired
on March 10, 2000, and March 10, 2001, respectively. Lynx is also entitled to
receive royalties on future sales of phosphorothioate antisense products. In
addition, Lynx is also entitled to receive royalties under a license to Inex for
phosphoroamidate chemistry for certain therapeutic applications in the fields of
cancer and inflammation.

4. SALE OF THE ANTISENSE BUSINESS (CONTINUED)

        The gain on the sale of the Antisense Business in 1998 is based on the
cash and the first installment of the Inex common stock received on the
transaction date, net of the book value of the assets transferred to Inex and
certain other costs associated with the transaction and incurred by Lynx.
Subsequent installments of Inex common stock are recorded at fair value by Lynx
in other income when received. As of December 31, 2000, Inex common stock was
classified as equity securities in short-term investments. As of December 31,
1999, Inex common stock was classified as equity securities in other non-current
assets.

5. LICENSE AGREEMENTS

        Lynx has entered into various license agreements with companies and
academic institutions. Such agreements generally require Lynx to pay annual or
semiannual license fees and are generally cancelable upon 60 to 120 days'
notice. The expenses associated with licenses were approximately $90,000 and
$86,000 for the years ended December 31, 2000 and 1999, respectively. Lynx
recorded a credit to expense of approximately $27,000 in the year ended December
31, 1998 for license fees which had been paid, then subsequently included in the
sale of the antisense business.


6. NOTES RECEIVABLE FROM OFFICERS

        In 1999, the Company entered into loan agreements with officers of the
Company. The aggregate loans total $360,000, are secured by second mortgages on
real property, have interest accruable at the rate of 4.83% to 6.02% per annum
and are subject to early repayment under specified circumstances. The principal
and interest on the loans will be forgiven, based on the officers' continuous
employment over a four-year period, in the following amounts: 50% on the second
anniversary dates of employment; and 25% on each of the third and fourth
anniversary dates of employment.

        In August 1998, the Company entered into two loan agreements with an
officer of the Company. Each loan is in the amount of $100,000, secured by a
second mortgage on real property, with interest accruable at the rate of 5.57%
per annum, and subject to early repayment under specified circumstances. The
principal and interest on one loan will be forgiven, based on the officer's
continuous employment over a four-year period, in the following amounts: 50% on
the second anniversary date of employment; and 25% on each of the third and
fourth anniversary dates of employment. The second loan is to be repaid by the
officer according to the following schedule: 50% of the principal on the third
anniversary date of employment; and the remainder of the principal plus accrued
interest on the fourth anniversary date of employment.

        In April 1997, the Company entered into a full-recourse loan agreement
with an officer of the Company. A note receivable of $250,000 was issued under a
stock purchase agreement for the purchase of 50,000 shares of common stock
whereby all the shares issued under the agreement are pledged as collateral. The
outstanding principal amount is due and payable in full in April 2002, subject
to an obligation to prepay under specified circumstances. Interest is payable
upon the expiration or termination of the note and accrues at the rate of 6.49%
per annum.

COMMON STOCK

        At December 31, 2000, Lynx has reserved 2,915,213 shares of common stock
for issuance upon the exercise of outstanding employee and nonemployee stock
options and upon the issuance of shares to be purchased pursuant to the employee
stock purchase plan as noted below:

</TABLE>


        In October 1997, Lynx issued 2,675,500 shares of common stock, resulting
in net proceeds of $25.1 million, pursuant to a common stock purchase agreement
between the Company and certain investors. In connection with this transaction,
warrants were issued by the Company to purchase 50,000 shares of common stock at
an exercise price of $14.00 per share. The warrants were exercised in January
2000.

        In November 1996, Lynx issued 959,182 shares of common stock in exchange
for 737,832 shares of Spectragen, Inc. common stock held by certain officers,
employees and one consultant of Spectragen, pursuant to an Agreement of Merger
between Lynx and Spectragen. Spectragen was a wholly-owned subsidiary of Lynx at
the time of the exchange. A portion of the shares are subject to repurchase
rights, which expire ratably over a five-year period. Pursuant to the merger,
and in accordance with APB 25, "Accounting for Stock Issued to Employees," Lynx
recognized compensation and consultant expense of $2.1 million and recorded
approximately $1.4 million in deferred compensation for the difference between
the fair market value of the Lynx stock and the deemed fair market value of the
Spectragen stock on the day of acquisition. The deferred compensation will be
charged ratably to expense as the repurchase rights expire.

        Also in November 1996, Lynx issued options to purchase 524,355 shares of
Lynx common stock in exchange for options to purchase 403,350 Spectragen common
stock pursuant to the Agreement of Merger between the Company and Spectragen. In
accordance with APB 25, Lynx recognized deferred compensation of $712,000
representing the difference between the exercise price of the options and the
fair market value of the Company's common stock on the day of the exchange. The
deferred compensation is being charged to expense over the respective vesting
period of the grants.

1992 STOCK OPTION PLAN

        In July 1992, the Board of Directors of the Company (the "Board")
adopted, and the stockholders subsequently approved, the Company's 1992 Stock
Option Plan (the "1992 Plan"). In May 2000, the stockholders approved an
amendment to the 1992 Plan, authorizing the increase in the number of shares
authorized for issuance under the 1992 Plan from a total of 4,200,000 shares to
4,800,000 shares and the inclusion of directors (including non-employee
directors) of the Company and its affiliates as eligible to participate in the
1992 Plan. In May 1996, the stockholders approved an amendment to the 1992 Plan
extending the term of the 1992 Plan until March 2006.

        Under the 1992 Plan, the exercise price of incentive options granted may
not be less than 100% (110% in the case of options granted to a person who owns
more than 10% of the total combined voting power of all classes of stock of the
Company) of the fair market value of common stock at the date of grant.
Nonqualified options may be granted at not less than 85% of fair market value at
the date of grant. Options generally vest over a five-year period from the date
of grant and have a term of ten years (five years in the case of options granted
to a person who owns more than 10% of the total combined voting power of all
classes of stock of the Company).

        In December 1997, the Board of Directors approved the commencement of
vesting of certain performance-based stock options that had been granted to
certain employees prior to the merger between Spectragen and Lynx. In connection
with this action, Lynx recognized deferred compensation of $4.1 million
representing the difference between the exercise price of the options and the
fair market value of the Company's common stock at the time of the December 1997
approval. The deferred compensation will be charged to expense over the period
beginning December 1997, through the end of the five-year vesting period.

PRO FORMA INFORMATION

        Pro forma information regarding net loss and net loss per share is
required by SFAS 123, and has been determined as if the Company had accounted
for its stock options granted subsequent to December 31, 1994 under the fair
value method of SFAS 123. The weighted average fair value of options granted in
2000, 1999 and 1998 was $20.38, $7.87 and $6.74 per share, respectively. The
fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model for the single option approach with the
following weighted-average assumptions: a risk-free interest rate of 6.0%, 4.97%
and 5.5% for 2000, 1999 and 1998, respectively; a weighted-average expected life
of five years for 2000 grants, five years for 1999 grants and 5.1 years for 1998
grants; an expected dividend yield of zero for all three years; and a volatility
factor of the expected market price of the Company's common stock of 100% for
2000, 86% for 1999 and 64% for 1998.

7. STOCKHOLDERS' EQUITY (CONTINUED)

        The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options that have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of the Company's stock options.

        Had compensation cost for the Company's stock-based compensation plan
been determined based on the fair value at the grant date for awards under the
plan consistent with the method of SFAS 123, the Company's net loss and net loss
per share would have been increased to the pro forma amounts indicated below:

stock purchase plan" as defined in Section 423 of the Internal Revenue Code.

        As of December 31, 2000, a total of 33,911 shares of common stock have
been issued to employees at an aggregate purchase price of $470,706 and a
weighted average purchase price of $13.88 per share pursuant to offerings under
the Purchase Plan, and 166,089 shares remain available for future issuance.

        Under SFAS 123, the fair value for these purchase options was estimated
at the date of grant using a Black-Scholes option pricing model with the
following weighted average assumptions for 2000 and 1999, respectively:
risk-free interest rate of 6.0% and 4.97%; no dividend yields; volatility factor
of the expected market price of the Company's common stock of 100% and 86%; and
a weighted average expected life of 0.55 and 0.49 years. The weighted average
fair value of those purchase rights granted in 2000 and 1999, respectively, was
$7.58 and $5.13.

8. INCOME TAXES

        The provision for income taxes of $500,000 for 2000 consists of foreign
withholding tax due on a payment received from one of Lynx's customers. The
provision for income taxes of approximately $258,000 for 1999 and $151,000 for
1998 consists entirely of alternative minimum tax.

        The reconciliation of income tax expense (benefit) attributable to
continuing operations computed at the U.S. federal statutory rates to income tax
expense (benefit) for the fiscal years ended December 31, 2000, 1999 and 1998 is

8. INCOME TAXES (CONTINUED)

        Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes. Significant
components of the Company's deferred tax assets are as follows (in thousands):

</TABLE>


        Realization of deferred tax assets is dependent on future earnings, if
any, the timing and the amount of which are uncertain. Accordingly, a valuation
allowance, in an amount equal to the net deferred tax assets as of December 31,
2000 and 1999 has been established to reflect these uncertainties. The change in
the valuation allowance was a net increase of approximately $9.6 million and
$3.6 million for the fiscal years ended December 31, 2000 and 1999,
respectively. Approximately $2.0 million of the valuation allowance for deferred
tax assets relates to benefits of stock option deductions which, when recognized
will be allocated directly to contributed capital.

        As of December 31, 2000, the Company had a federal net operating loss
carryforward of approximately $38.6 million, which will expire at various dates
from 2008 through 2020, if not utilized. The Company has a state net operating
loss carryforward of approximately $5.3 million, which will expire in 2010.

        As of December 31, 2000, the Company also had federal and California
research and development and other tax credit carryforwards of approximately
$3.8 million and $1.3 million, respectively. The federal research and
development credit will expire at various dates from 2008 through 2020, if not
utilized.

        Utilization of net operating loss and tax credit carryforwards may be
subject to a substantial annual limitation due to the ownership change
limitations provided by the Internal Revenue Code of 1986, as amended, and
similar state provisions. The annual limitation may result in expiration of net
operating loss and tax credit carryforwards before full utilization. Utilization
of federal and California net operating losses and credit carryforwards incurred
prior to February 1994 is limited on an annual basis under the Internal Revenue
Code of 1986, as amended, as a result of an ownership change in 1994.

9. OBLIGATIONS UNDER OPERATING LEASES

        In August 1993, the Company entered into a noncancelable operating lease
for facilities which expires on July 31, 2003. In 1998, the Company entered into
an agreement to sublease a portion of this space, and in 1999 through a
subsequent agreement, subleased the remaining portion of the facility. The term
of the sublease runs through July 2003. Rent from the sublease is sufficient to
cover the rent and other operating expenses incurred by Lynx under the terms of
the 1993 Lease.

        In February 1998, the Company entered into a noncancelable operating
lease for facilities. The term of the lease commenced on December 15, 1998 and
expires on December 14, 2008. Under the terms of the lease, the monthly rental
payments are fixed for the first 24 months. Thereafter, the monthly rental
payments increase and are subject to annual Consumer Price Index-based
adjustments, with minimum and maximum limits. The Company is recognizing rent
expense on a straight-line basis over the lease period. The Company has the
option to extend the lease for an additional five-year period, subject to
certain conditions, with payments to be determined at the time of the exercise
of the option.

9. OBLIGATIONS UNDER OPERATING LEASES (CONTINUED)

        In June 1998, Lynx GmbH entered into a noncancelable operating lease for
facilities space of approximately 6,300 square feet in Heidelberg, Germany, to
house its operations. The space will be developed and occupied in phases,
depending on the growth of the organization. The lease terminates in June 2005.
A portion of such space is currently being subleased by BASF-LYNX.

        The Company also leases equipment under various operating lease
agreements subject to minimum annual lease payments. Minimum annual rental
commitments and sublease income under non-cancelable operating leases are as
follows (in thousands):

        Rent expense for facilities and equipment under operating leases was
$2,055,000, $1,733,000 and $738,000 for the years ended December 31, 2000, 1999
and 1998, respectively. Rental income for the facility under sublease was
$1,127,000, $990,000 and $186,000 for the years ended December 31, 2000, 1999
and 1998, respectively.

10. 401(k) PLAN

        In October 1992, Lynx adopted a 401(k) Plan covering all of its
employees. Pursuant to the 401(k) Plan, employees may elect to reduce their
current compensation by up to 15% (subject to an annual limit prescribed by the
Code as described below) and have the amount of such reduction contributed to
the 401(k) Plan. The 401(k) Plan permits, but does not require, additional
contributions to the 401(k) Plan by Lynx on behalf of all participants in the
401(k) Plan. In the years ended 2000, 1999 and 1998, the Company contributed
$74,000, $52,000 and $49,000, respectively.

11. EQUIPMENT FINANCING

        In 1998, the Company entered into a financing agreement with a financial
institution ("Lender") under which Lynx drew down $4.8 million during 1999 for
the purchase of equipment and certain other capital expenditures. Lynx granted
the lender a security interest in all items financed by the Company under this
agreement. Each draw down under the loan has a term of 48 months from the date
of the draw down at interest rates ranging from 10.9% to 11.8% The original draw
down period under the agreement expired on March 31, 2000. In September 2000,
Lynx obtained additional financing of $950,000, under an amendment to the
original financing agreement. As of December 31, 2000, the principal balance
under loans outstanding under this agreement was approximately $4.4 million.
Accumulated depreciation relating to these assets amounted to $2.5 million and
$0.7 million for the years ended December 31, 2000 and 1999, respectively. The
carrying amounts of the Company's borrowings under its equipment financing
approximate their fair values. The fair values are estimated using a discounted
cash flow analysis based on the Company's current incremental borrowing rates
for similar types of borrowing arrangements.

        Principal payments based on equipment loans outstanding at December 31,
2000 are (in thousands):

12. SUBSEQUENT EVENTS (UNAUDITED)

        Phytera

        In January 2001, the Company entered into a collaboration with Phytera,
Inc. to identify genes from plants involved in the biosynthesis of anti-oxidant
polyphenols, naturally occurring compounds with nutraceutical and pharmaceutical
activity. Phytera will select plant species from its culture libraries and apply
its proprietary ExPAND(R) manipulation technology to regulate the expression of
the metabolic pathways and genes responsible for the production of specific
anti-oxidant polyphenolic compounds. Lynx will then use its proprietary Megasort
technology to identify genes activated after target compounds are induced. Lynx
and Phytera intend to validate gene targets and jointly commercialize the genes
with other partners in the nutraceutical and pharmaceutical sectors.

        Celera

        In March 2001, the Company entered into two agreements with Celera
Genomics. The first agreement involves the integration of sets of Lynx's
high-resolution gene expression data, derived from normal human tissues analyzed
using Lynx's MPSS technology, into Celera's database products for distribution
to Celera's customers through the Celera Discovery System (CDS). Under a second
agreement, Lynx will apply its MPSS technology to perform additional gene
expression analyses various tissues for Celera and to help supplement the Lynx
database offering.

        In June 2001, Lynx extended its technology licensing agreement with
BASF-LYNX. The license extends BASF-LYNX's right to use Lynx's proprietary
MPSS(TM) and Megasort(TM) technologies non-exclusively in BASF-LYNX's
neuroscience, toxicology and microbiology research programs until December 31,
2007. The agreement also uniquely positions BASF-LYNX to apply Lynx's
technologies to specific disorders in the neuroscience field. Under the terms of
the agreement, Lynx will receive from BASF-LYNX a multi-million dollar
technology license fee. Lynx will furnish BASF-LYNX, initially without charge
and later for a fee, with Megaclone(TM) technology micro-beads, other reagents
and additional MPSS(TM) technology instruments for use in BASF-LYNX's research
programs.

        Separately, Lynx and BASF have agreed to continue their support of
BASF-LYNX's growth, including an increase of the capital reserves of BASF-LYNX.
Lynx's additional investment in BASF-LYNX will maintain Lynx's ownership
interest in BASF-LYNX at more than 40%.

(2)     The potential realizable value is calculated based on the term of the
        option at its time of grant (ten years). It is calculated by assuming
        that the stock price on the date of grant appreciates at the indicated
        annual rate, compounded annually for the entire term of the option, and
        that option is exercised and sold on the last day of the term for the
        appreciated stock price.

        The following table sets forth certain information concerning the number
of options exercised by the Named Executive Officers during the year ended
December 31, 2000, and the number of shares covered by both exercisable and
unexercisable stock options held by the Named Executive Officers. Also reported
are values for "in-the-money" options that represent the positive spread between
the respective exercise prices of outstanding options and the fair market value
of the Company's common stock as of December 29, 2000 ($9.00 per share).

        29, 2000 ($9.00), minus the exercise price of the options, multiplied by
        the number of shares underlying the options.

EMPLOYMENT SEVERANCE AND CHANGE OF CONTROL AGREEMENTS

        In October 1999, the Company entered into an employment agreement with
Dr. Norman J. W. Russell, President and Chief Executive Officer, providing for
an annual compensation of $255,000 per year and an option to purchase 200,000
shares of common stock at an exercise price of $11.31 per share, subject to a
five-year vesting schedule. If Dr. Russell is terminated due to a change in
control of the Company, Dr. Russell's shares covered by the option shall
accelerate so that fifty percent of the then unvested shares covered by the
option shall immediately vest and become exercisable upon the effective date of
the change in control. The Company also provided Dr. Russell with a loan in the
amount of $250,000 for the sole purpose of the purchase of a house, which loan
shall be secured by the property, and is forgivable over a four-year period.

COMPENSATION OF DIRECTORS

        Directors are not compensated by the Company for services as directors.
Non-employee directors are eligible to participate in the Company's 1992 Plan.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        The Company's Compensation Committee was established in March 1994 and
is currently composed of three non-employee directors: Messrs. Bowes, Kitch and
Taylor. Mr. Taylor served as Acting Chief Financial Officer of the Company from
July 1994 to April 1997. There were no officers or employees of the Company who
participated in deliberations of the Company's Compensation Committee concerning
executive officer compensation during the year ended December 31, 2000.

LIMITATIONS OF LIABILITY AND INDEMNIFICATION

        The Company's Bylaws provide that the Company will indemnify its
directors and executive officers and may indemnify its other officers, employees
and other agents to the fullest extent permitted by Delaware law. The Company is
also empowered under its Bylaws to enter into indemnification agreements with
its directors and officers and to purchase insurance on behalf of any person
whom it is required or permitted to indemnify. Pursuant to this provision, the
Company has entered into indemnity agreements with each of its directors and
executive officers.


                                       50
<PAGE>   53
        In addition, the Company's Certificate of Incorporation provides that,
to the fullest extent permitted by Delaware law, the Company's directors will
not be liable for monetary damages for breach of the directors' fiduciary duty
of care to the Company and its stockholders. This provision in the Certificate
of Incorporation does not eliminate the duty of care, and in appropriate
circumstances, equitable remedies such as an injunction or other forms of
nonmonetary relief would remain available under Delaware law. Each director will
continue to be subject to liability for breach of the director's duty of loyalty
to the Company, for acts or omissions not in good faith or involving intentional
misconduct or knowing violations of law, for acts or omissions that the director
believes to be contrary to the best interests of the Company or its
stockholders, for any transaction from which the director derived an improper
personal benefit, for acts or omissions involving a reckless disregard for the
director's duty to the Company or its stockholders when the director was aware
or should have been aware of a risk of serious injury to the Company or its
stockholders, for acts or omissions that constitute an unexcused pattern of
inattention that amounts to an abdication of the director's duty to the Company
or its stockholders, for improper transactions between the director and the
Company and for improper distributions to stockholders and loans to directors
and officers. This provision also does not affect a director's responsibilities
under any other laws such as the federal securities laws or state or federal
environmental laws.

        No pending material litigation or proceeding involving a director,
officer, employee or other agent of the Company as to which indemnification is
being sought exists, and the Company is not aware of any pending or threatened
material litigation that may result in claims for indemnification by any
director, officer, employee or other agent.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        In November 1999, the Company entered into a loan agreement with Norman
J. W. Russell, Ph.D., President, Chief Executive Officer and a director of the
Company. The loan is in the amount of $250,000, secured by a second mortgage on
real property, with interest accruable at the rate of 6.02% per annum, and
subject to early repayment under specified circumstances. The principal and
interest on the loan will be forgiven, based on the officer's continuous
employment over a four-year period, in the following amounts: 50% on the second
anniversary date of employment; and 25% on each of the third and fourth
anniversary dates of employment. At February 15, 2001, the outstanding principal
and accrued interest on the loan was $267,224.

        In April 1997, the Company entered into a full-recourse loan agreement
with Edward C. Albini, an officer of the Company. A note receivable of $250,000
was issued under a stock purchase agreement for the purchase of 50,000 shares of
common stock whereby all the shares issued under the agreement are pledged as
collateral. The outstanding principal amount is due and payable in full in April
2002, subject to an obligation to prepay under specified circumstances. Interest
is payable upon the expiration or termination of the note and accrues at the
rate of 6.49% per annum. At February 15, 2001, the outstanding principal and
accrued interest on the loan was $293,988.

        For legal services rendered during the calendar year ended December 31,
2000, the Company paid approximately $307,500 to Cooley Godward LLP, the
Company's counsel, of which Mr. Kitch, a director of the Company, is a partner.

        The Company's Bylaws provide that the Company will indemnify its
directors and executive officers and may indemnify its other officers, employees
and other agents to the fullest extent permitted by Delaware law. The Company is
also empowered under its Bylaws to enter into indemnification agreements with
its directors and officers and to purchase insurance on behalf of any person
whom it is required or permitted to indemnify. Pursuant to this provision, the
Company has entered into indemnity agreements with each of its directors and
executive officers.
