                                   ABOUT GERON

     We are a biopharmaceutical company focused on developing and
commercializing therapeutic and diagnostic products for applications in oncology
and regenerative medicine, and research tools for drug discovery. Our product
development programs are based upon three patented core technologies:
telomerase, human embryonic stem cells and nuclear transfer.

     We were incorporated in 1990 under the laws of Delaware. Our principal
executive offices are located at 230 Constitution Drive, Menlo Park, California
94025 and our telephone number is (650) 473-7700. References in this prospectus
to "we," "us," "our," and "Geron" refer to Geron Corporation and its
subsidiaries.

                                  RISK FACTORS

     Before you decide whether to purchase any of our securities, in addition to
the information in this prospectus, you should carefully consider the following
risk factors, as well as the risk factors set forth under the heading "Risk
Factors" in the section entitled "Item 1 -- Business" in our most recent Annual
Report on Form 10-K, which is incorporated by reference into this prospectus, as
the same may be updated from time to time by our future filings under the
Securities Exchange Act. For more information, see the section entitled "Where
You Can Find More Information."


OUR BUSINESS IS AT AN EARLY STAGE OF DEVELOPMENT



     The study of the mechanisms of cellular aging and cellular immortality,
including telomere biology and telomerase, the study of human embryonic stem
cells, and the process of nuclear transfer are relatively new areas of research.
Our business is at an early stage of development. Our ability to produce
products that progress to and through clinical trials is subject to our ability
to, among other things:


     o    continue to have success with our research and development efforts;

     o    select therapeutic compounds for development;

     o    obtain the required regulatory approvals; and

     o    manufacture and market resulting products.


     When potential lead drug compounds or product candidates are identified
through our research programs, they will require significant preclinical and
clinical testing prior to regulatory approval in the United States and
elsewhere. In addition, we will also need to determine whether any of these
potential products can be manufactured in commercial quantities at an acceptable
cost. Our efforts may not result in a product that can be marketed. Because of
the significant scientific, regulatory and commercial milestones that must be
reached for any of our research programs to be successful, any program may be
abandoned, even after significant resources have been expended.



WE HAVE A HISTORY OF OPERATING LOSSES AND ANTICIPATE FUTURE LOSSES, CONTINUED
LOSSES COULD IMPAIR OUR ABILITY TO SUSTAIN OPERATIONS



     We have incurred net operating losses every year since our operations began
in 1990. As of September 30, 2001, our accumulated deficit was approximately
$172.4 million. Losses have resulted principally from costs incurred in
connection with our research and development activities and from general and
administrative costs associated with our operations. We expect to incur
additional operating losses over the next several years as our research and
development efforts and preclinical testing activities are expanded.
Substantially all of our revenues to date have been research support payments
under the collaboration agreements with Kyowa Hakko and Pharmacia. In 2001, we
regained our rights to telomerase inhibitors from Pharmacia and we will not
receive future payments from Pharmacia. Kyowa Hakko provided additional research
funding in 2001. We may be unsuccessful in entering into any new corporate
collaboration that results in revenues. Even if we are able to obtain new
collaboration arrangements with third parties, the revenues generated from these
arrangements will be insufficient to continue or expand our research activities
and otherwise sustain our operations.


     We are unable to estimate at this time the level of revenue to be received
from the sale of diagnostic products and telomerase-immortalized cell lines, and
do not currently expect to receive significant revenues from the sale of these
products. Our ability to continue or expand our research activities and
otherwise sustain our operations is dependent on our ability, alone or with
others to, among other things, manufacture and market therapeutic products.



     We may never receive material revenues from product sales or if we do
receive revenues, such revenues may not be sufficient to continue or expand our
research activities and otherwise sustain our operations.

WE WILL NEED ADDITIONAL CAPITAL TO CONDUCT OUR OPERATIONS AND DEVELOP OUR
PRODUCTS, AND OUR ABILITY TO OBTAIN THE NECESSARY FUNDING IS UNCERTAIN

     We will require substantial capital resources in order to conduct our
operations and develop our products. While we estimate that our existing capital
resources, interest income and equipment financing arrangements will be
sufficient to fund our current level of operations through December 31, 2002, we
cannot guarantee that this will be the case. The timing and degree of any future
capital requirements will depend on many factors, including:

     o    the accuracy of the assumptions underlying our estimates for our
          capital needs in 2001 and beyond;

     o    continued scientific progress in our research and development
          programs;

     o    the magnitude and scope of our research and development programs;

     o    our ability to maintain and establish strategic arrangements for
          research, development, clinical testing, manufacturing and marketing;

     o    our progress with preclinical and clinical trials;

     o    the time and costs involved in obtaining regulatory approvals;

     o    the costs involved in preparing, filing, prosecuting, maintaining,
          defending and enforcing patent claims; and

     o    the potential for new technologies and products.


     We intend to acquire additional funding through strategic collaborations,
public or private equity financings, capital lease transactions or other
financing sources that may be available. Additional financing may not be
available on acceptable terms, or at all. Additional equity financings could
result in significant dilution to stockholders. Further, in the event that
additional funds are obtained through arrangements with collaborative partners,
these arrangements may require us to relinquish rights to some of our
technologies, product candidates or products that we would otherwise seek to
develop and commercialize ourselves. If sufficient capital is not available, we
may be required to delay, reduce the scope of or eliminate one or more of our
research or development programs, each of which could have a material adverse
effect on our business.



WE MAY BE UNABLE TO IDENTIFY A SAFE AND EFFECTIVE INHIBITOR OF TELOMERASE WHICH
MAY PREVENT US FROM DEVELOPING A VIABLE CANCER TREATMENT PRODUCT, WHICH WOULD
ADVERSELY IMPACT OUR FUTURE BUSINESS PROSPECTS



     As a result of our drug discovery efforts to date, we have identified
compounds in laboratory studies that demonstrate potential for inhibiting
telomerase in humans. Kyowa Hakko has selected one of these compounds, GRN 163,
as a lead compound for preclinical development as a telomerase inhibitor for
cancer. Further research is required to determine if this compound can be fully
developed as a efficacious, safe and commercially viable treatment for cancer.



     This compound, and other compounds we have identified, may prove to have
undesirable and unintended side effects or other characteristics adversely
affecting its safety or efficacy that would likely prevent or limit its
commercial use. Accordingly, it may not be appropriate for us to proceed with
clinical development, to obtain regulatory approval or to market a telomerase
inhibitor for the treatment of cancer. If we abandon our research for cancer
treatment for any of these reasons or for other reasons, our business prospects
would be materially and adversely affected.



                                       2



IF OUR ACCESS TO NECESSARY TISSUE SAMPLES, INFORMATION OR LICENSED TECHNOLOGIES
IS RESTRICTED, WE WILL NOT BE ABLE TO DEVELOP OUR BUSINESS

     To continue the research and development of our therapeutic and diagnostic
products, we need access to normal and diseased human and other tissue samples,
other biological materials and related clinical and other information. We
compete with many other companies for these materials and information. We may
not be able to obtain or maintain access to these materials and information on
acceptable terms, if at all. In addition, government regulation in the United
States and foreign countries could result in restricted access to, or
prohibiting the use of, human and other tissue samples. If we lose access to
sufficient numbers or sources of tissue samples, or if tighter restrictions are
imposed on our use of the information generated from tissue samples, our
business will be materially harmed.

SOME OF OUR COMPETITORS MAY DEVELOP TECHNOLOGIES THAT ARE SUPERIOR TO OR MORE
COST-EFFECTIVE THAN OURS, WHICH MAY IMPACT THE COMMERCIAL VIABILITY OF OUR
TECHNOLOGIES AND WHICH MAY SIGNIFICANTLY DAMAGE OUR ABILITY TO SUSTAIN
OPERATIONS

     The pharmaceutical and biotechnology industries are intensely competitive.
We believe that other pharmaceutical and biotechnology companies and research
organizations currently engage in or have in the past engaged in efforts related
to the biological mechanisms of cell aging and cell immortality, including the
study of telomeres, telomerase, human embryonic stem cells and nuclear transfer.
In addition, other products and therapies that could compete directly with the
products that we are seeking to develop and market currently exist or are being
developed by pharmaceutical and biopharmaceutical companies and by academic and
other research organizations.

     Many companies are also developing alternative therapies to treat cancer
and, in this regard, are competitors of ours. Many of the pharmaceutical
companies developing and marketing these competing products have significantly
greater financial resources and expertise than we do in:

     o    research and development;

     o    manufacturing;

     o    preclinical and clinical testing;

     o    obtaining regulatory approvals; and

     o    marketing.

     Smaller companies may also prove to be significant competitors,
particularly through collaborative arrangements with large and established
companies. Academic institutions, government agencies and other public and
private research organizations may also conduct research, seek patent protection
and establish collaborative arrangements for research, clinical development and
marketing of products similar to ours. These companies and institutions compete
with us in recruiting and retaining qualified scientific and management
personnel as well as in acquiring technologies complementary to our programs.
There is also competition for access to libraries of compounds to use for
screening. Should we fail to secure and maintain access to sufficiently broad
libraries of compounds for screening potential targets, our business would be
materially harmed.

     In addition to the above factors, we expect to face competition in the
following areas:

     o    product efficacy and safety;

     o    the timing and scope of regulatory consents;

     o    availability of resources;


                                       3



     o    reimbursement coverage;

     o    price; and

     o    patent position, including potentially dominant patent positions of
          others.

     As a result of the foregoing, our competitors may develop more effective or
more affordable products, or achieve earlier patent protection or product
commercialization than us. Most significantly, competitive products may render
the products that we develop obsolete.

THE ETHICAL, LEGAL AND SOCIAL IMPLICATIONS OF OUR RESEARCH USING EMBRYONIC STEM
CELLS AND NUCLEAR TRANSFER COULD PREVENT US FROM DEVELOPING OR GAINING
ACCEPTANCE FOR COMMERCIALLY VIABLE PRODUCTS IN THIS AREA

     Our programs in regenerative medicine may involve the use of human
embryonic stem cells that would be derived from human embryonic or fetal tissue.
The use of human embryonic stem cells gives rise to ethical, legal and social
issues regarding the appropriate use of these cells. In the event that our
research related to human embryonic stem cells becomes the subject of adverse
commentary or publicity, the market price for our common stock could be
significantly harmed.


     Some groups have voiced opposition to our technology and practices. The
concepts of cell regeneration, cell immortality, and genetic cloning have
stimulated significant debate in social and political arenas. We use human
embryonic stem cells derived through a process that uses either donated embryos
that are no longer needed following a successful in vitro fertilization
procedure or donated fetal material as the starting material. Further, many
research institutions, including some of our scientific collaborators, have
adopted policies regarding the ethical use of human embryonic and fetal tissue.
These policies may have the effect of limiting the scope of research conducted
using human embryonic stem cells, resulting in reduced scientific progress. In
addition, the United States government and its agencies have in recent years
refused to fund research which involves the use of human embryonic tissue.
President Bush, however, announced on August 9, 2001 that he would permit
federal funding of research on human embryonic stem cells using the limited
number of embryonic stem cell lines that had already been created. A newly
created president's council will monitor stem cell research, and the guidelines
and regulations it recommends may include restrictions on the scope of research
using human embryonic or fetal tissue. Our inability to conduct research using
human embryonic stem cells due to such factors as government regulation or
otherwise could have a material adverse effect on us. Finally, we acquired
Roslin Bio-Med to gain the rights to nuclear transfer technology. The Roslin
Institute produced Dolly the sheep in 1997 -- the first mammal cloned from an
adult cell in history. Geron acquired exclusive rights to this technology for
all areas except human reproductive cloning and certain other limited
applications. Although we will not be pursuing human reproductive cloning, we
continue to develop techniques for use in agricultural cloning and for possible
application in regenerative medicine. Government imposed restrictions with
respect to any or all of these practices could:


     o    harm our ability to establish critical partnerships and
          collaborations;

     o    prompt government regulation of our technologies;

     o    cause delays in our research and development; and

     o    cause a decrease in the price of our stock.


     If human therapeutic cloning is restricted or banned (as it would be under
bill H.R. 2505 recently passed by the U.S. House of Representatives), our
ability to commercialize those applications could be significantly harmed. Also,
if regulatory bodies were to ban nuclear transfer processes, our research using
nuclear transfer technology could be cancelled and our business could be
significantly harmed.



                                       4



PUBLIC ATTITUDES TOWARDS GENE THERAPY MAY NEGATIVELY AFFECT REGULATORY APPROVAL
OR PUBLIC PERCEPTION OF OUR PRODUCTS

     The commercial success of our product candidates will depend in part on
public acceptance of the use of gene therapies for the prevention or treatment
of human diseases. Public attitudes may be influenced by claims that gene
therapy is unsafe, and gene therapy may not gain the acceptance of the public or
the medical community. Adverse events in the field of gene therapy that have
occurred or may occur in the future also may result in greater governmental
regulation of our product candidates and potential regulatory delays relating to
the testing or approval of our product candidates.

     Negative public reaction to gene therapy in the development of certain of
our therapies could result in greater government regulation, stricter clinical
trial oversight, restrictive commercial product labeling requirements of gene
therapies, and could cause a decrease in the demand for any products that we may
develop. The subject of genetically modified organisms has received negative
publicity in Europe, which has aroused public debate. The adverse publicity in
Europe could lead to greater regulation and trade restrictions on imports of
genetically altered products. If similar adverse public reaction occurs in the
United States, genetic research and resultant products could be subject to
greater domestic regulation and could cause a decrease in the demand for our
potential products.


ENTRY INTO CLINICAL TRIALS WITH ONE OR MORE PRODUCTS MAY NOT RESULT IN ANY
COMMERCIALLY VIABLE PRODUCTS


     We do not expect to generate any significant revenues from product sales
for a period of several years. We may never generate revenues from product sales
or become profitable because of a variety of risks inherent in our business,
including risks that:

     o    clinical trials may not demonstrate the safety and efficacy of our
          products;

     o    completion of clinical trials may be delayed, or costs of clinical
          trials may exceed anticipated amounts;

     o    we may not be able to obtain regulatory approval of our products, or
          may experience delays in obtaining such approvals;

     o    we may not be able to manufacture our drugs economically on a
          commercial scale;

     o    we and our licensees may not be able to successfully market our
          products;

     o    physicians may not prescribe our products, or patients may not accept
          such products;

     o    others may have proprietary rights which prevent us from marketing our
          products; and

     o    competitors may sell similar, superior or lower-cost products.

IMPAIRMENT OF OUR INTELLECTUAL PROPERTY RIGHTS MAY LIMIT OUR ABILITY TO PURSUE
THE DEVELOPMENT OF OUR INTENDED TECHNOLOGIES AND PRODUCTS

     Our success will depend on our ability to obtain and enforce patents for
our discoveries; however, legal principles for biotechnology patents in the
United States and in other countries are not firmly established and the extent
to which we will be able to obtain patent coverage is uncertain.


     Protection of our proprietary compounds and technology is critically
important to our business. Our success will depend in part on our ability to
obtain and enforce our patents and maintain trade secrets, both in the United
States and in other countries. The patent positions of pharmaceutical and
biopharmaceutical companies, including ours, are highly uncertain and involve
complex legal and technical questions. We may not continue to develop products
or processes that are patentable, and it is possible that patents will not issue
from any of our pending applications, including allowed patent applications.
Further, our current patents, or patents that issue on pending applications, may
be challenged, invalidated or circumvented, and our current or future patent
rights may not provide proprietary protection or competitive advantages to us.
In the event that we are unsuccessful in obtaining and enforcing patents, our
business would be negatively impacted.



                                       5



     Patent applications filed in the United States prior to November 29, 2000,
are maintained in secrecy until patents issue. Publication of discoveries in the
scientific or patent literature tends to lag behind actual discoveries by at
least several months and sometimes several years. Therefore, the publications
may reveal in the future that the persons or entities that we or our licensors
name as inventors in our patents and patent applications may not have been the
first to invent the inventions disclosed in the patent applications or patents,
or file patent applications for these inventions. As a result, we may not be
able to obtain patents from discoveries that we otherwise would consider
patentable and that we consider to be significant to our future success.

     Patent prosecution, interference, opposition proceeding or litigation may
also be necessary to obtain patents, enforce any patents issued or licensed to
us or to determine the scope and validity of our proprietary rights or the
proprietary rights of another. We may not be successful in any patent
prosecution, interference, opposition proceeding or litigation. Patent
prosecution and litigation in general can be extremely expensive and time
consuming, even if the outcome is favorable to us. An adverse outcome in a
patent prosecution or litigation or any other proceeding in a court or patent
office could weaken our proprietary position, subject our business to
significant liabilities to other parties, require disputed rights to be licensed
from other parties or require us to cease using the disputed technology.


IF WE FAIL TO MEET OUR OBLIGATIONS UNDER LICENSE AGREEMENTS, WE MAY FACE LOSS
OF OUR RIGHTS TO KEY TECHNOLOGIES ON WHICH OUR BUSINESS DEPENDS.



     Our business depends on our three core technologies, each of which is based
in part on patents licensed from third parties. Those third party license
agreements impose obligations on us, such as payment obligations and obligations
to diligently pursue development of commercial products under the licensed
patents. If a licensor believes we have failed to meet our obligations under a
license agreement, the licensor could seek to limit or terminate our license
rights, which would most likely lead to costly and time-consuming litigation.
During the period of any such litigation our ability to carry out the
development and commercialization of potential products could be significantly
and negatively affected. If our license rights were ultimately lost, our ability
to carry on our business based on the affected technology platform would be
severely affected.



     For example, as we stated in our Form 8-K filed on November 5, 2001, and
our Form 10-Q for the fiscal quarter ended September 30, 2001, the Wisconsin
Alumni Research Foundation, or WARF, has expressed dissatisfaction with the
development plans we submitted to WARF under our 1999 license agreement and
about our progress in commercializing therapeutic products based on the WARF
patents on human embryonic stem cells. We believe that our development of the
technology has been diligent and that our development plans are both reasonable
and consistent with our obligations under the license agreement. We are
committed to resolving our differences with WARF amicably, but we may be
unable to do so. If we do not reach a settlement and WARF seeks to reduce or
terminate our rights, our ability to carry out the development and
commercialization of products based on human embryonic stem cells would be
severely affected until and unless the resulting litigation is concluded
successfully.



WE ARE AND IN THE FUTURE MAY BE SUBJECT TO LITIGATION THAT WILL BE COSTLY TO
DEFEND OR PURSUE AND UNCERTAIN IN ITS OUTCOME.



     Our business may bring us into conflict with our licensees, licensors, or
others with whom we have contractual or other business relationships, or with
our competitors or others whose interests differ from ours. If we are unable to
resolve those conflicts on terms that are satisfactory to all parties, we may
become involved in litigation brought by or against us. That litigation is
likely to be expensive and may require a significant amount of management's
time and attention, at the expense of other aspects of our business. The
outcome of litigation is always uncertain, and in some cases could include
judgments against us that require us to pay damages, enjoin us from certain
activities, or otherwise affect our legal or contractual rights, which could
have a significant effect on our business.



     For example, the Wisconsin Alumni Research Foundation, or WARF, has brought
a lawsuit against our company seeking a declaratory judgment concerning our
rights and WARF's obligations under a 1999 license agreement between us and
WARF. The license agreement covers the commercialization of six cell types made
from human embryonic stem cells. This lawsuit addresses our option to obtain an
exclusive license to cell types in addition to the six cell types already
licensed to us and the scope of our exclusive license to commercialize research
products based on those six cell types. We have had and expect to continue to
have discussions with WARF about settling the lawsuit. If we do not reach a
settlement, however, and our defense of the case is unsuccessful, our ability to
commercialize research products could be significantly affected.




WE MAY BE SUBJECT TO INFRINGEMENT CLAIMS THAT ARE COSTLY TO DEFEND, AND WHICH
MAY LIMIT OUR ABILITY TO USE DISPUTED TECHNOLOGIES AND PREVENT US FROM PURSUING
RESEARCH AND DEVELOPMENT OR COMMERCIALIZATION OF POTENTIAL PRODUCTS



     Our commercial success depends significantly on our ability to operate
without infringing patents and proprietary rights of others. Our technologies
may infringe the patents or proprietary rights of others. In addition, we may
become aware of discoveries and technology controlled by third parties that are
advantageous to our research programs. In the event our technologies do infringe
on the rights of others or we require the use of discoveries and technology
controlled by third parties, we may be prevented from pursuing research,
development or commercialization of potential products or may be required to
obtain licenses to these patents or other proprietary rights or develop or
obtain alternative technologies. We may not be able to obtain alternative
technologies or any required license on commercially favorable terms, if at all.
If we do not obtain the necessary licenses or alternative technologies, we may
be delayed or prevented from pursuing the development of some potential
products. Our failure to obtain alternative technologies or a license to any
technology that we may require to develop or commercialize our products will
significantly and negatively affect our business.



     Patent law relating to the scope and enforceability of claims in the
technology fields in which we operate is still evolving, and the degree of
future protection for any of our proprietary rights is highly uncertain. In this
regard, patents may not issue from any of our patent applications or our
existing patents may be found to be invalid by a court. In addition, our success
may become dependent on our ability to obtain licenses for using the patented
discoveries of others. We are aware of patent applications and patents that have
been filed by others with respect to our technologies and we may have to obtain
licenses to use these technologies. Moreover, other patent applications may be
granted priority over patent applications that we or any of our licensors have
filed. Furthermore, others may independently develop similar or alternative
technologies, duplicate our technologies or design around the patented
technologies we have developed. In the event that we are unable to acquire
licenses to critical technologies that we cannot patent ourselves, we may be
required to expend significant time and resources to develop alternative
technology, and we may not be successful in this regard. If we cannot acquire or
develop the necessary technology, we may be prevented from pursuing some of our
business objectives. Moreover, one or more of our competitors could acquire or
license the necessary technology. Any of these events could materially harm our
business.



                                       6



MUCH OF THE INFORMATION AND KNOW-HOW THAT IS CRITICAL TO OUR BUSINESS IS NOT
PATENTABLE AND WE MAY NOT BE ABLE TO PREVENT OTHERS FROM OBTAINING THIS
INFORMATION AND ESTABLISHING COMPETITIVE ENTERPRISES

     We sometimes rely on trade secrets to protect our proprietary technology,
especially in circumstances in which patent protection is not believed to be
appropriate or obtainable. We attempt to protect our proprietary technology in
part by confidentiality agreements with our employees, consultants,
collaborators and contractors. We cannot assure you that these agreements will
not be breached, that we would have adequate remedies for any breach, or that
our trade secrets will not otherwise become known or be independently discovered
by competitors, any of which would harm our business significantly.

WE DEPEND ON OUR COLLABORATORS TO HELP US COMPLETE THE PROCESS OF DEVELOPING AND
TESTING OUR PRODUCTS AND OUR ABILITY TO DEVELOP AND COMMERCIALIZE PRODUCTS MAY
BE IMPAIRED OR DELAYED IF OUR COLLABORATIVE PARTNERSHIPS ARE UNSUCCESSFUL

     Our strategy for the development, clinical testing and commercialization of
our products requires entering into collaborations with corporate partners,
licensors, licensees and others. We are dependent upon the subsequent success of
these other parties in performing their respective responsibilities and the
continued cooperation of our partners. Our collaborators may not cooperate with
us or perform their obligations under our agreements with them. We cannot
control the amount and timing of our collaborators' resources that will be
devoted to our research activities related to our collaborative agreements with
them. Our collaborators may choose to pursue existing or alternative
technologies in preference to those being developed in collaboration with us.


     Our ability to successfully develop and commercialize a telomerase
inhibitor in Asia depends on our corporate alliance with Kyowa Hakko. Our
ability to successfully develop and commercialize telomerase diagnostic products
depends on our corporate alliance with Roche Diagnostics. Under our
collaborative agreements with these collaborators, we rely significantly on
them, among other activities, to:


     o    design and conduct advanced clinical trials in the event that we reach
          clinical trials;

     o    fund research and development activities with us;

     o    pay us fees upon the achievement of milestones; and


     o    market with us any commercial products that result from our
          collaborations.



     The development and commercialization of products from these collaborations
will be delayed if Kyowa Hakko or Roche Diagnostics fail to conduct these
collaborative activities in a timely manner or at all. In addition, Kyowa Hakko
or Roche Diagnostics could terminate their agreements with us and we may not
receive any development or milestone payments. If we do not achieve milestones
set forth in the agreements, or if Kyowa Hakko or Roche Diagnostics or any of
our future collaborators breach or terminate collaborative agreements with us,
our business may be materially harmed.


OUR RELIANCE ON THE RESEARCH ACTIVITIES OF OUR NON-EMPLOYEE SCIENTIFIC ADVISORS
AND OTHER RESEARCH INSTITUTIONS, WHOSE ACTIVITIES ARE NOT WHOLLY WITHIN OUR
CONTROL, MAY LEAD TO DELAYS IN TECHNOLOGICAL DEVELOPMENTS

     We rely extensively and have relationships with scientific advisors at
academic and other institutions, some of whom conduct research at our request.
These scientific advisors are not our employees and may have commitments to, or
consulting or advisory contracts with, other entities that may limit their
availability to us. We have limited control over the activities of these
advisors and, except as otherwise required by our collaboration and consulting
agreements, can expect only limited amounts of their time to be dedicated to our
activities. If our scientific advisors are unable or refuse to contribute to the
development of any of our potential discoveries, our ability to generate
significant advances in our technologies may be significantly harmed.


                                       7



     In addition, we have formed research collaborations with many academic and
other research institutions throughout the world, including the Roslin
Institute. These research facilities may have commitments to other commercial
and non-commercial entities. We have limited control over the operations of
these laboratories and can expect only limited amounts of time to be dedicated
to our research goals.

THE LOSS OF KEY PERSONNEL COULD SLOW OUR ABILITY TO CONDUCT RESEARCH AND DEVELOP
PRODUCTS

     Our future success depends to a significant extent on the skills,
experience and efforts of our executive officers and key members of our
scientific staff. Competition for personnel is intense and we may be unable to
retain our current personnel or attract or assimilate other highly qualified
management and scientific personnel in the future. The loss of any or all of
these individuals could harm our business and might significantly delay or
prevent the achievement of research, development or business objectives.

     We also rely on consultants and advisors, including the members of our
Scientific Advisory Board, who assist us in formulating our research and
development strategy. We face intense competition for qualified individuals from
numerous pharmaceutical, biopharmaceutical and biotechnology companies, as well
as academic and other research institutions. We may not be able to attract and
retain these individuals on acceptable terms. Failure to do so would materially
harm our business.

WE MAY NOT BE ABLE TO OBTAIN OR MAINTAIN SUFFICIENT INSURANCE ON COMMERCIALLY
REASONABLE TERMS OR WITH ADEQUATE COVERAGE AGAINST POTENTIAL LIABILITIES IN
ORDER TO PROTECT OURSELVES AGAINST PRODUCT LIABILITY CLAIMS

     Our business exposes us to potential product liability risks that are
inherent in the testing, manufacturing and marketing of human therapeutic and
diagnostic products. We may become subject to product liability claims if the
use of our products is alleged to have injured subjects or patients. This risk
exists for products tested in human clinical trials as well as products that are
sold commercially. We currently have no clinical trial liability insurance and
we may not be able to obtain and maintain this type of insurance for any of our
clinical trials. In addition, product liability insurance is becoming
increasingly expensive. As a result, we may not be able to obtain or maintain
product liability insurance in the future on acceptable terms or with adequate
coverage against potential liabilities which could have a material adverse
effect on us.

BECAUSE WE OR OUR COLLABORATORS MUST OBTAIN REGULATORY APPROVAL TO MARKET OUR
PRODUCTS IN THE UNITED STATES AND FOREIGN JURISDICTIONS, WE CANNOT PREDICT
WHETHER OR WHEN WE WILL BE PERMITTED TO COMMERCIALIZE OUR PRODUCTS


     Federal, state and local governments in the United States and governments
in other countries have significant regulations in place that govern many of our
activities. The preclinical testing and clinical trials of the products that we
develop ourselves or that our collaborators develop are subject to extensive
government regulation and may prevent us from creating commercially viable
products from our discoveries. In addition, the sale by us or our collaborators
of any commercially viable product will be subject to government regulation from
several standpoints, including the processes of:


     o    manufacturing;

     o    advertising and promoting;

     o    selling and marketing;

     o    labeling; and

     o    distributing.


                                       8



     We may not obtain regulatory approval for the products we develop and our
collaborators may not obtain regulatory approval for the products they develop.
Regulatory approval may also entail limitations on the indicated uses of a
proposed product. Because certain of our product candidates involve the
application of new technologies and may be based upon a new therapeutic
approach, such products may be subject to substantial additional review by
various government regulatory authorities, and, as a result, we may obtain
regulatory approvals for such products more slowly than for products based upon
more conventional technologies. If, and to the extent that, we are unable to
comply with these regulations, our ability to earn revenues will be materially
and negatively impacted.


     The regulatory process, particularly for biopharmaceutical products like
ours, is uncertain, can take many years and requires the expenditure of
substantial resources. Any product that we or our collaborative partners develop
must receive all relevant regulatory agency approvals or clearances, if any,
before it may be marketed in the United States or other countries. Generally,
biological drugs and non-biological drugs are regulated more rigorously than
medical devices. In particular, human pharmaceutical therapeutic products are
subject to rigorous preclinical and clinical testing and other requirements by
the Food and Drug Administration in the United States and similar health
authorities in foreign countries. The regulatory process, which includes
extensive preclinical testing and clinical trials of each product in order to
establish its safety and efficacy, is uncertain, can take many years and
requires the expenditure of substantial resources.



     Data obtained from preclinical and clinical activities is susceptible to
varying interpretations that could delay, limit or prevent regulatory agency
approvals or clearances. In addition, delays or rejections may be encountered as
a result of changes in regulatory agency policy during the period of product
development and/or the period of review of any application for regulatory agency
approval or clearance for a product. Delays in obtaining regulatory agency
approvals or clearances could:


     o    significantly harm the marketing of any products that we or our
          collaborators develop;

     o    impose costly procedures upon our activities or the activities of our
          collaborators;

     o    diminish any competitive advantages that we or our collaborative
          partners may attain; or

     o    adversely affect our ability to receive royalties and generate
          revenues and profits.


     Even if we commit the necessary time and resources, economic and otherwise,
the required regulatory agency approvals or clearances may not be obtained for
any products developed by or in collaboration with us. If regulatory agency
approval or clearance for a new product is obtained, this approval or clearance
may entail limitations on the indicated uses for which it may be marketed that
could limit the potential commercial use of the product. Furthermore, approved
products and their manufacturers are subject to continual review, and discovery
of previously unknown problems with a product or its manufacturer may result in
restrictions on the product or manufacturer, including withdrawal of the product
from the market. Failure to comply with regulatory requirements can result in
severe civil and criminal penalties, including but not limited to:


     o    recall or seizure of products;

     o    injunction against manufacture, distribution, sales and marketing; and

     o    criminal prosecution.

     The imposition of any of these penalties could significantly impair our
business, financial condition and results of operations.


                                       9



TO BE SUCCESSFUL, OUR PRODUCTS MUST BE ACCEPTED BY THE HEALTH CARE COMMUNITY,
WHICH CAN BE VERY SLOW TO ADOPT OR UNRECEPTIVE TO NEW TECHNOLOGIES AND PRODUCTS

     Our products and those developed by our collaborative partners, if approved
for marketing, may not achieve market acceptance since physicians, patients or
the medical community in general may decide not to accept and utilize these
products. The products that we are attempting to develop may represent
substantial departures from established treatment methods and will compete with
a number of traditional drugs and therapies manufactured and marketed by major
pharmaceutical companies. The degree of market acceptance of any of our
developed products will depend on a number of factors, including:

     o    our establishment and demonstration to the medical community of the
          clinical efficacy and safety of our product candidates;

     o    our ability to create products that are superior to alternatives
          currently on the market;

     o    our ability to establish in the medical community the potential
          advantage of our treatments over alternative treatment methods; and

     o    reimbursement policies of government and third-party payors.

     If the health care community does not accept our products for any of the
foregoing reasons, or for any other reason, our business would be materially
harmed.

THE REIMBURSEMENT STATUS OF NEWLY-APPROVED HEALTH CARE PRODUCTS IS UNCERTAIN AND
FAILURE TO OBTAIN REIMBURSEMENT APPROVAL COULD SEVERELY LIMIT THE USE OF OUR
PRODUCTS

     Significant uncertainty exists as to the reimbursement status of newly
approved health care products, including pharmaceuticals. If we fail to generate
adequate third party reimbursement for the users of our potential products and
treatments, then we may be unable to maintain price levels sufficient to realize
an appropriate return on our investment in product development.

     In both domestic and foreign markets, sales of our products, if any, will
depend in part on the availability of reimbursement from third-party payors,
examples of which include:

     o    government health administration authorities;

     o    private health insurers;

     o    health maintenance organizations; and

     o    pharmacy benefit management companies.

     Both federal and state governments in the United States and foreign
governments continue to propose and pass legislation designed to contain or
reduce the cost of health care through various means. Legislation and
regulations affecting the pricing of pharmaceuticals and other medical products
may change or be adopted before any of our potential products are approved for
marketing. Cost control initiatives could decrease the price that we receive for
any product we may develop in the future. In addition, third-party payors are
increasingly challenging the price and cost-effectiveness of medical products
and services and any of our potential products and treatments may ultimately not
be considered cost effective by these third parties. Any of these initiatives or
developments could materially harm our business.

OUR ACTIVITIES INVOLVE HAZARDOUS MATERIALS AND IMPROPER HANDLING OF THESE
MATERIALS BY OUR EMPLOYEES OR AGENTS COULD EXPOSE US TO SIGNIFICANT LEGAL AND
FINANCIAL PENALTIES

     Our research and development activities involve the controlled use of
hazardous materials, chemicals and various radioactive compounds. As a
consequence, we are subject to numerous environmental and safety laws and
regulations, including those governing laboratory procedures, exposure to
blood-borne pathogens and the handling of biohazardous materials. We may be
required to incur significant costs to comply with current or future
environmental laws and regulations and may be adversely affected by the cost of
compliance with these laws and regulations.


                                       10



     Although we believe that our safety procedures for using, handling, storing
and disposing of hazardous materials comply with the standards prescribed by
state and federal regulations, the risk of accidental contamination or injury
from these materials cannot be eliminated. In the event of such an accident,
state or federal authorities could curtail our use of these materials and we
could be liable for any civil damages that result, the cost of which could be
substantial. Further, any failure by us to control the use, disposal, removal or
storage of, or to adequately restrict the discharge of, or assist in the cleanup
of, hazardous chemicals or hazardous, infectious or toxic substances could
subject us to significant liabilities, including joint and several liability
under certain statutes, and any liability could exceed our resources and could
have a material adverse effect on our business, financial condition and results
of operations. Additionally, an accident could damage our research and
manufacturing facilities and operations.

     Additional federal, state and local laws and regulations affecting us may
be adopted in the future. We may incur substantial costs to comply with and
substantial fines or penalties if we violate any of these laws or regulations.

OUR STOCK PRICE HAS HISTORICALLY BEEN VERY VOLATILE


     Stock prices and trading volumes for many biopharmaceutical companies
fluctuate widely for a number of reasons, including some reasons which may be
unrelated to their businesses or results of operations such as media coverage,
legislation and regulatory measures and the activities of various interest
groups or organizations. This market volatility, as well as general domestic or
international economic, market and political conditions, could materially and
adversely affect the market price of our common stock and the return on your
investment.



     Historically, our stock price has been extremely volatile. Between January
1998 and September 30, 2001, our stock has traded as high as $75.88 per share
and as low as $3.50 per share. The significant market price fluctuations of our
common stock are due to a variety of factors, including:


     o    depth of the market for the common stock;

     o    the experimental nature of our prospective products;

     o    fluctuations in our operating results;

     o    market conditions relating to the biopharmaceutical and pharmaceutical
          industries;

     o    any announcements of technological innovations, new commercial
          products or clinical progress or lack thereof by us, our collaborative
          partners or our competitors; and

     o    announcements concerning regulatory developments, developments with
          respect to proprietary rights and our collaborations.

     In addition, the stock market is subject to other factors outside our
control that can cause extreme price and volume fluctuations. Securities class
action litigation has often been brought against companies, including many
biotechnology companies, when they experience volatility in the market price of
their securities. Litigation brought against us could result in substantial
costs and a diversion of management's attention and resources, which could
adversely affect our business.

THE SALE OF A SUBSTANTIAL NUMBER OF SHARES, INCLUDING SHARES THAT WILL BECOME
ELIGIBLE FOR SALE IN THE NEAR FUTURE, MAY ADVERSELY AFFECT THE MARKET PRICE FOR
OUR COMMON STOCK


     Sales of substantial number of shares of our common stock in the public
market could significantly and negatively affect the market price for our common
stock. As of September 30, 2001, we had 22,024,257 shares of common stock
outstanding. Of these shares, 10,529,534 shares were issued (including shares
issuable upon conversion or exercise of convertible notes or warrants) since
December 1998 pursuant to private placements. Of these shares, 9,623,463 shares
have been registered pursuant to shelf registration statements and therefore may
be resold (if not sold prior to the date hereof) in the public market and
906,071 of the remaining shares may be resold pursuant to Rule 144 into the
public markets as early as March 9, 2002, upon the expiration of a lockup
agreement with us.



                                       11



OUR UNDESIGNATED PREFERRED STOCK MAY INHIBIT POTENTIAL ACQUISITION BIDS; THIS
MAY ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK AND THE VOTING RIGHTS
OF THE HOLDERS OF COMMON STOCK

     Our certificate of incorporation provides our Board of Directors with the
authority to issue up to 3,000,000 shares of undesignated preferred stock and to
determine the rights, preferences, privileges and restrictions of these shares
without further vote or action by the stockholders. As of the date of this Form
S-3, the Board of Directors still has authority to designate and issue up to
2,950,000 shares of preferred stock. The rights of the holders of common stock
will be subject to, and may be adversely affected by, the rights of the holders
of any preferred stock that may be issued in the future. The issuance of shares
of preferred stock may delay or prevent a change in control transaction without
further action by our stockholders. As a result, the market price of our common
stock may be adversely affected. The issuance of preferred stock may also result
in the loss of voting control by others.


PROVISIONS IN OUR SHARE PURCHASE RIGHTS PLAN, OUR CHARTER AND BYLAWS, AND
PROVISIONS OF DELAWARE LAW, MAY INHIBIT POTENTIAL ACQUISITION BIDS FOR US, WHICH
MAY PREVENT HOLDERS OF OUR COMMON STOCK FROM BENEFITING FROM WHAT THEY MAY
BELIEVE MAY BE THE POSITIVE ASPECTS OF ACQUISITIONS AND TAKEOVERS





     Our Board of Directors has adopted a share purchase rights plan, commonly
referred to as a "poison pill". This plan entitles existing stockholders to
rights, including the right to purchase shares of common stock, in the event of
an acquisition of 15% or more of our outstanding common stock. Our share
purchase rights plan could prevent stockholders from profiting from an increase
in the market value of their shares as a result of a change of control of Geron
by delaying or preventing a change of control. In addition, our Board of
Directors has the authority, without further action by our stockholders, to
issue additional shares of common stock, to fix the rights and preferences of,
and to issue authorized but undesignated shares of preferred stock.



     In addition to our share purchase rights plan and undesignated preferred
stock, provisions of our charter documents and bylaws may make it substantially
more difficult for a third party to acquire control of us and may prevent
changes in our management, including provisions that:


     o    prevent stockholders from taking actions by written consent;

     o    divide the Board of Directors into separate classes with terms of
          office that are structured to prevent all of the directors from being
          elected in any one year; and

     o    set forth procedures for nominating directors and submitting proposals
          for consideration at stockholders' meetings.




     Provisions of Delaware law may also inhibit potential acquisition bids for
us or prevent us from engaging in business combinations. Either collectively or
individually, these provisions may prevent holders of our common stock from
benefiting from what they may believe are the positive aspects of acquisitions
and takeovers, including the potential realization of a higher rate of return on
their investment from these types of transactions.

                           FORWARD-LOOKING STATEMENTS

     This prospectus and the documents incorporated by reference into this
prospectus contain forward-looking statements that are based on current
expectations, estimates and projections about our industry, management's
beliefs, and assumptions made by management. Words such as "anticipates,"
"expects," "intends," "plans," "believes," "seeks," "estimates," and variations
of such words and similar expressions are intended to identify such
forward-looking statements. These statements are not guarantees of future
performance and are subject to certain risks, uncertainties and assumptions that
are difficult to predict; therefore, actual results may differ materially from
those expressed or forecasted in any forward-looking statements. The risks and
uncertainties include those noted in "Risk Factors" above and in the documents
incorporated by reference. We undertake no obligation to update publicly any
forward-looking statements, whether as a result of new information, future
events or otherwise.

                                 USE OF PROCEEDS

     The proceeds from the sale of the common stock sold pursuant to this
prospectus will belong to the selling stockholder. We will not receive any
proceeds from such sales.

                               SELLING STOCKHOLDER


     The following table sets forth the name of the selling stockholder, the
number of shares of common stock owned beneficially by the selling stockholder
as of November 7, 2001, the number of shares which may be offered pursuant to
this prospectus and the number of shares to be owned by the selling stockholder
after this offering. The selling stockholder may sell up to 200,000 shares of
our common stock pursuant to this prospectus. Since the selling stockholder may
offer all, some or none of its common stock, no definitive estimate as to the
number of shares thereof that will be held by the selling stockholder after the
offering can be provided. In addition, since the date the selling stockholders
provided information regarding their ownership of the shares, they may have
sold, transferred or otherwise disposed of all or a portion of their shares of
common stock in transactions exempt from the registration requirements of the
Securities Act. Information concerning the selling stockholder may change from
time to time and, when necessary, any changed information will be set forth in a
prospectus supplement to this prospectus.


     On August 30, 2001, we issued a total of 100,000 shares of our common stock
to University Technology Corporation pursuant to a common stock purchase
agreement with University Technology Corporation. On August 30, 2001, we also
issued to University Technology Corporation a warrant to purchase up to 100,000
shares of our common stock at a purchase price of $14.60 per share, pursuant to
a common stock warrant agreement dated as of August 30, 2001. The warrant is
exercisable for a period of ten years after the date of issuance. The number of
shares that we have registered is based upon the actual number of shares issued
to the selling stockholder pursuant to the common stock purchase agreement and
the maximum number issuable upon exercise of the warrant.

     To our knowledge, the stockholder named in the table has sole voting and
investment power with respect to all shares of common stock beneficially owned.
This information is based upon information provided by the selling stockholder.

                              PLAN OF DISTRIBUTION

     We are registering 200,000 shares of our common stock on behalf of the
selling stockholder. The selling stockholder and any of its pledgees, assignees
and successors-in-interest may, from time to time, sell any or all of the shares
of common stock offered hereby 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 stockholder may use any one or more of
the following methods when selling shares:

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

     o    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;

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

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

     o    privately negotiated transactions;

     o    short sales;

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

     o    a combination of any such methods of sale; and

     o    any other method permitted pursuant to applicable law.

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

     The selling stockholder may also engage in short sales against the box,
puts and calls and other transactions in our securities or derivatives of our
securities and may sell or deliver shares in connection with these trades. The
selling stockholder may pledge its shares to its brokers under the margin
provisions of customer agreements. If the selling stockholder defaults on a
margin loan, the broker may, from time to time, offer and sell the pledged
shares. The selling stockholder has advised us that it has not entered into any
agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of its shares other than ordinary course
brokerage arrangements, nor is there an underwriter or coordinating broker
acting in connection with the proposed sale of shares by the selling
stockholder.

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

     The selling stockholder 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.


                                       14



     Upon notification to us by the selling stockholder that any material
arrangement has been entered into 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, we will file a supplement to
this prospectus, if required, pursuant to Rule 424(b) under the Securities Act,
disclosing the following:

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

     o    the number of shares involved;

     o    the price at which such shares were sold;

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

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

     o    other facts material to the transaction.

In addition, we will file a supplement to this prospectus when the selling
stockholder notifies us that a donee or pledgee intends to sell more than 500
shares of our common stock.

     We have advised the selling stockholder that the anti-manipulation
provisions of Regulation M promulgated under the Securities Exchange Act of 1934
may apply to their sales of our shares offered by this prospectus.

                                  LEGAL MATTERS

     Latham & Watkins will pass on the validity of the issuance of the shares of
common stock offered by this prospectus.

        LIMITATION ON LIABILITY AND DISCLOSURE OF COMMISSION POSITION ON
                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

     Our bylaws provide for indemnification of our directors and officers to the
fullest extent permitted by law. Insofar as indemnification for liabilities
under the Securities Act may be permitted to directors, officers or controlling
persons of Geron pursuant to Geron's Certificate of Incorporation, bylaws and
the Delaware General Corporation Law, Geron has been informed that in the
opinion of the SEC such indemnification is against public policy as expressed in
the Securities Act and is therefore unenforceable.

Item 15. Indemnification of Directors and Officers.

     Section 145 of the Delaware General Corporation Law allows for the
indemnification of officers, directors, and other corporate agents in terms
sufficiently broad to indemnify these persons for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act. The
registrant's certificate of incorporation and bylaws provide for indemnification
of the registrant's directors, officers, employees and other agents to the
extent and under the circumstances permitted by the Delaware General Corporation
Law. The registrant has also entered into agreements with its directors and
officers that will require the registrant, among other things, to indemnify them
against liabilities that may arise by reason of their status or service as
directors to the fullest extent not prohibited by law. In addition, the
registrant carries director and officer liability insurance.

Item 17. Undertakings.

     (a) The undersigned registrant hereby undertakes:

          (1) To file, during any period in which it offers or sells securities,
a post-effective amendment to this registration statement to include any
additional or changed information on the plan of distribution.

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

          (3) To file a post-effective amendment to remove from registration any
of the securities that remain unsold at the end of the offering.


                                      II-1




     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) 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 such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (c) The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or
given, the latest annual report, to security holders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of
1934; and, where interim financial information required to be presented by
Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or
cause to be delivered to each person to whom the prospectus is sent or given,
the latest quarterly report that is specifically incorporated by reference in
the prospectus to provide such interim financial information.

     (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such 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 such
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 Act and will be governed by the final adjudication of
such issue.

                                   SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-3 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in Menlo Park, State of California, on November 8, 2001.
