                                      LYNX

    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.

    The primary genomics application we have developed that leverages the power
of Megaclone is Massively Parallel Signature Sequencing, or MPSS. MPSS 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.

    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. Lynx is also developing a proteomics
technology, Protein ProFiler, which is expected to provide high-resolution
analysis of complex mixtures of proteins from cells or tissues. Proteomics is
the study of the number of proteins and the extent to which they are expressed
in cells or tissues.

    Lynx was incorporated in Delaware in February 1992. Our executive offices
are located at 25861 Industrial Boulevard, Hayward, California 94545, and our
telephone number is (510) 670-9300.

RECENT DEVELOPMENTS

    On April 29, 2002, we sold 14,600,000 newly issued shares of our common
stock at a purchase price of $1.55 per share and warrants to purchase up to
5,840,000 shares of our common stock at an exercise price of $1.94 per share for
an aggregate purchase price of approximately $22,630,000. In addition, we issued
a warrant to purchase up to 292,000 shares of our common stock at an exercise
price of $1.55 per share to Friedman, Billings, Ramsey & Co., Inc. as partial
compensation, in addition to customary fees, for services rendered to us in
connection with the private placement transaction.

                                  RISK FACTORS

    You should carefully consider the following risk factors, in addition to
other information included or incorporated by reference in this prospectus,
before making an investment decision. Additional risks that we do not yet know
of or that we currently think are immaterial may also impair our business
operations. If any of the events or circumstances described in the following
risks actually occurs, our business may suffer, the trading price of our common
stock could decline and you may lose all or part of your investment.

WE HAVE A HISTORY OF 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 $6.7 million in 1999, $13.3 million in 2000 and
$16.7 million in 2001. As of December 31, 2001, we had an accumulated deficit of
approximately $83.4 million. Future net losses or profits 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;

    -   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


                                       2.



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 and proteomics 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, protein 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, proteins 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 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 year
ended December 31, 2001, revenues from DuPont, BASF, Takara and the Institute of
Molecular and Cell Biology accounted for 37%, 24%, 12% and 12%, 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%, 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. 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;


                                       3.



    -   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 and proteomics
research is a rapidly evolving field. Competition among entities attempting to
identify genes and proteins 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 and proteins;

    -   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 and protein expression analysis
        methodologies, including the use of chip-based systems, to attempt to
        identify disease-related genes and proteins.

    In addition, numerous pharmaceutical, biotechnology and agricultural
companies are developing genomics and proteomics 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.


                                       4.



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 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, proteins, the analysis of gene expression and protein 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 protein expression and
for the individual disease genes and proteins 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.


                                       5.



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

    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 and
proteomics 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 may 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 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


                                       6.



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 or proteins 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.

    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.


                                       7.



    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 March 31, 2000 to March
31, 2002, the closing sales price of our common stock as quoted on the Nasdaq
National Market fluctuated from a low of $2.02 to a high of $48.75 per share. In
addition, the securities 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.

    Any authorization or issuance of preferred stock, while providing desirable
flexibility in connection with financings, 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.


                                       8.

                                 USE OF PROCEEDS

    The proceeds from the sale of the common stock offered pursuant to this
prospectus are solely for the accounts of the selling stockholders. We will not
receive any proceeds from the sale of these shares of common stock.

                              SELLING STOCKHOLDERS

    We issued 14,600,000 shares of our common stock, and warrants to purchase up
to 5,840,000 shares of our common stock, in a private placement transaction. In
addition, we issued a warrant to purchase up to 292,000 shares of our common
stock to Friedman, Billings, Ramsey & Co., Inc. as partial compensation, in
addition to customary fees, for services rendered to us in connection with the
private placement transaction. We are registering the 20,732,000 shares covered
by this prospectus on behalf of the selling stockholders named in the table
below. We agreed to register all of the above referenced shares of common stock
for resale in connection with the terms and conditions of the private placement
transaction. We have registered the shares to permit each of the selling
stockholders and its pledgees, donees, transferees or other
successors-in-interest that receive their shares from each selling stockholder
as a gift, partnership distribution or other non-sale related transfer after the
date of this prospectus to resell the shares.

    The following table sets forth the name of each selling stockholder, the
number of shares owned by it, the number of shares that may be offered under
this prospectus and the number of shares of our common stock owned by the
selling stockholder after this offering is completed. Except as otherwise
disclosed below, none of the selling stockholders has, or within the past three
years has had, any position, office or other material relationship with us. The
number of shares in the column "Number of Shares Being Offered" represents all
of the shares that a selling stockholder may offer under this prospectus, and
assumes the exercise of all the warrants for common stock. The selling
stockholders may sell some, all or none of their shares. We do not know how long
the selling stockholders will hold the shares before selling them, and we
currently have no agreements, arrangements or understandings with the selling
stockholders regarding the sale of any of the shares. The shares offered by this
prospectus may be offered from time to time by the selling stockholders.

    Beneficial ownership is determined in accordance with Rule 13d-3(d)
promulgated by the SEC under the Securities Exchange Act of 1934. Unless
otherwise noted, none of the share amounts set forth below represents more than
1% of our outstanding stock as of April 29, 2002, adjusted as required by rules
promulgated by the SEC. The percentages of shares beneficially owned prior to
the offering are based on 28,405,453 shares of our common stock outstanding as
of April 29, 2002, (which includes the sale of the 14,600,000 shares to the
selling stockholders in the private placement), plus the shares of common stock
issuable upon exercise of the warrants for common stock held by the respective
selling stockholder.

                              PLAN OF DISTRIBUTION

    The selling stockholders and any of their pledgees, assignees and
successors-in-interest (including distributees) may, from time to time, sell any
or all of their shares of common stock. The selling stockholders will act
independently of us in making decisions regarding the timing, manner and size of
each sale. The sales may be made on any stock exchange, market or trading
facility on which the shares are traded or in private transactions. These sales
may be at fixed or negotiated prices. The selling stockholders may use any one
or more of the following methods when selling shares:

    -   ordinary brokerage transactions and transactions in which the
        broker-dealer solicits purchasers;

    -   block trades in which the broker-dealer will attempt to sell the shares
        as agent but may position and resell a portion of the block as principal
        to facilitate the transaction;

    -   purchases by a broker-dealer as principal and resale by the
        broker-dealer for its account;

    -   an exchange distribution in accordance with the rules of the applicable
        exchange;

    -   privately negotiated transactions;

    -   short sales;

    -   broker-dealers may agree with the selling shareholders to sell a
        specified number of shares at a stipulated price per share;

    -   option agreements;

    -   a combination of any such methods of sale; and

    -   any other method permitted pursuant to applicable law.

    The selling stockholders may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

    To the extent required, this prospectus may be amended or supplemented from
time to time to describe a specific plan of distribution. If the plan of
distribution involves an arrangement with a broker-dealer for the sale of shares
through a block trade, special offering, exchange distribution or secondary
distribution or a purchase by a broker or dealer, the amendment or supplement
will disclose:

    -   the name of the selling stockholder and of the participating
        broker-dealer(s);

    -   the number of shares involved;

    -   the price at which the shares were sold;

    -   the commissions paid or discounts or concessions allowed to the
        broker-dealer(s), where applicable;


                                      15.



    -   that a broker-dealer(s) did not conduct any investigation to verify the
        information set out or incorporated by reference in this prospectus; and

    -   other facts material to the transaction.

    From time to time, a selling stockholder may transfer, pledge, donate or
assign its shares of common stock to lenders or others, and each of such persons
will be deemed to be a "selling stockholder" for purposes of this prospectus.
The number of shares of common stock beneficially owned by the selling
stockholder will decrease as and when it takes such actions. The plan of
distribution for the selling stockholder's shares of common stock sold under
this prospectus will otherwise remain unchanged, except that the transferees,
pledgees, donees or other successors will be selling stockholders hereunder.

    The selling stockholders may also engage in short sales against the box,
puts and calls and other transactions in securities of Lynx or derivatives of
Lynx securities and may sell or deliver shares in connection with these trades.
The selling stockholders may pledge their shares to their brokers under the
margin provisions of customer agreements. If a selling stockholder defaults on a
margin loan, the broker may, from time to time, offer and sell the pledged
shares. Lynx is not aware of any agreements, understandings or arrangements with
any selling stockholders and underwriters or broker-dealers regarding the sale
of their shares other than ordinary course brokerage arrangements.

    Broker-dealers engaged by the selling stockholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the selling stockholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. The selling stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved.

    The selling stockholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of the
shares purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act. Because a selling stockholder may be deemed
to be an "underwriter" within the meaning of the Securities Act, the selling
stockholder will be subject to the prospectus delivery requirements of the
Securities Act.

    The shares will be sold only through registered or licensed brokers or
dealers if required under applicable state securities laws. In addition, in some
states the shares may not be sold unless they have been registered or qualified
for sale in the applicable state or an exemption from the registration or
qualification requirement is available and is complied with.

    Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the shares may not simultaneously engage in
market making activities with respect to our common stock for a period of two
business days prior to the commencement of the distribution. In addition, the
selling stockholders will be subject to applicable provisions of the Exchange
Act and the associated rules and regulations under the Exchange Act, including
Regulation M, which provisions may limit the timing of purchases and sales of
shares of our common stock by the selling stockholders. We will make copies of
this prospectus available to the selling stockholders and have informed the
selling stockholders of the need to deliver copies of this prospectus to
purchasers at or prior to the time of any sale of the shares.

    Lynx is required to pay all fees and expenses incident to the registration
of the shares. The selling stockholders will pay all commissions and discounts,
if any, attributable to the sales of the shares. The selling stockholders may
agree to indemnify any broker-dealer or agent that participates in transactions
involving sales of the shares against specific liabilities, including
liabilities arising under the Securities Act. Lynx has agreed to indemnify the
selling stockholders against certain losses, claims, damages and liabilities,
including liabilities under the Securities Act.


                                      16.



    We have agreed to use best efforts to maintain the effectiveness of this
registration statement under the Securities Act as long as delivery of a
prospectus is required under the Securities Act in connection with the
disposition of the shares being registered hereunder.

stock and options to purchase 20,000 shares of our common stock. In addition,

ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

    We will bear no expenses in connection with any sale or other distribution
by the selling stockholders of the shares being registered other than the
expenses of preparation and distribution of this registration statement and the
prospectus included in this registration statement. The extent of these expenses
is set forth in the following table. All of the amounts shown are estimates
except the SEC registration fee.



                                                               
SEC registration fee ...........................................  $ 3,176

Miscellaneous expenses .........................................    8,824

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    As permitted by Delaware law, our amended and restated certificate of
incorporation provides that no director of ours will be personally liable to us
or our stockholders for monetary damages for breach of fiduciary duty as a
director, except for liability:

    -   for any breach of duty of loyalty to us or to our stockholders;

    -   for acts or omissions not in good faith or that involve intentional
        misconduct or a knowing violation of law;

    -   for unlawful payment of dividends or unlawful stock repurchases or
        redemptions under Section 174 of the Delaware General Corporation Law;
        or

    -   for any transaction from which the director derived an improper personal
        benefit.

    Our amended and restated certificate of incorporation further provides that
we must indemnify our directors and executive officers and may indemnify our
other officers and employees and agents to the fullest extent permitted by
Delaware law. We believe that indemnification under our amended and restated
certificate of incorporation covers negligence and gross negligence on the part
of indemnified parties.

    We have entered into indemnification agreements with each of our directors
and certain officers. These agreements, among other things, require us to
indemnify each director and officer for certain expenses including attorneys'
fees, judgments, fines and settlement amounts incurred by any such person in any
action or proceeding, including any action by or in the right of Lynx
Therapeutics, Inc., arising out of the person's services as our director or
officer, any subsidiary of ours or any other company or enterprise to which the
person provides services at our request.

    At present, there is no pending litigation or proceeding involving a
director or officer of Lynx as to which indemnification is being sought nor are
we aware of any threatened litigation that may result in claims for
indemnification by any officer or director.

ITEM 17. UNDERTAKINGS

    The undersigned registrant hereby undertakes:

    (1) To file, during any period in which offers or sales are being made, a
        post-effective amendment to this registration statement to include any
        material information with respect to the plan of distribution not
        previously disclosed in the registration statement or any material
        change to that information in the registration statement.

    (2) That, for the purpose of determining any liability under the Securities
        Act, each post-effective amendment shall be deemed to be a new
        registration statement relating to the securities it offers, and the
        offering of the securities at that time shall be deemed to be the
        initial bona fide offering thereof.

    (3) To remove from registration by means of a post-effective amendment any
        of the securities being registered which remain unsold at the
        termination of this offering.

    (4) That, for purposes of determining any liability under the Securities
        Act, each filing of the registrant's annual report pursuant to Section
        13(a) or Section 15(d) of the Exchange Act that is incorporated by
        reference in the registration statement shall be deemed to be a new
        registration statement relating to the securities offered therein, and
        the offering of the securities at that time shall be deemed to be the
        initial bona fide offering thereof.

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the SEC this form of indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against these
liabilities





(other than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by a director, officer or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of this issue.
