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.  Telomeres are the
ends of  chromosomes  that protect  chromosomes  from  degradation  and act as a
molecular  "clock" for cellular  aging.  Telomerase  is an enzyme that  restores
telomere length and rewinds the molecular  "clock," thereby extending the cell's
ability to multiply or replicate. By activating telomerase,  we seek to increase
the  lifespan of normal cells which have  prematurely  aged in the body to treat
certain chronic degenerative  diseases.  Conversely,  by inhibiting or targeting
telomerase we hope to kill cancer cells in which telomerase is abnormally turned
on and to diagnose cancer by measuring telomerase activity. Human embryonic stem
cells can develop and  differentiate  into all cells and tissues in the body. As
such, they are a potential  source for the manufacture of replacement  cells and
tissues for organ repair applications in regenerative medicine. Nuclear transfer
(sometimes  called  "somatic cell nuclear  transfer") is a method for generating
whole animals from genetic  material derived solely from the nucleus of a single
cell obtained from a single animal. We are actively licensing this technology to
others for applications in agriculture and production of biologicals.

     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.

RISK FACTORS

     Our business is subject to various risks,  including those described below.
You should carefully consider these risk factors, together with all of the other
information  included  in this Form S-3.  Any of these  risks  could  materially
adversely affect our business, operating results and financial condition.

Our business is at an early stage of development.

     The  science and  technology  of telomere  biology  and  telomerase,  human
embryonic stem cells,  and nuclear  transfer are relatively new. Our business is
at an  early  stage  of  development,  in that we do not yet  have  products  in
late-stage  clinical  trials or on the market.  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 development programs to be successful, any program may be
abandoned, even after significant resources have been expended.

We have a history of losses and anticipate future losses; continued losses could
impair our ability to sustain operations.

     We have incurred  operating losses every year since our operations began in
1990. As of June 30, 2003,  our  accumulated  deficit was  approximately  $243.0
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 as our development efforts and clinical testing activities are continued.
Substantially  all of our revenues to date have been research  support  payments
under


                                       4



collaboration agreements. 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 may not be sufficient alone to continue or expand our
research or development 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
or development 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 and planned  operations through June 30, 2005, 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 2003 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  stockholder.  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
programs, any of which could have a material adverse effect on our business.

We may be unable to identify a safe and effective inhibitor of telomerase that
can be developed into a commercially 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. We have selected one of these compounds, GRN163, as a lead
compound for development as a telomerase inhibitor for cancer.  Further research
is  required  to  determine  if  this  compound  can be  fully  developed  as an
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, efficacy or cost-effectiveness that would likely prevent


                                       5


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.

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.
Other  pharmaceutical  and  biotechnology  companies and research  organizations
currently  engage  in or have in the past  engaged  in  efforts  related  to the
biological  mechanisms  that  are the  focus of our  programs  in  oncology  and
regenerative  medicine,  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.  According to published reports as
of December 2002, there are  approximately 90 approved  anti-cancer  products on
the market in the United States,  and several  hundred in clinical  development.
Many of the  pharmaceutical  companies  developing and marketing these competing
products  (including  Astra-Zeneca,  Bristol-Meyers  Squibb and Novartis,  among
others) 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.

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

    o  product efficacy and safety;


                                       6



    o  the timing and scope of regulatory consents;

    o  availability of resources;

    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 we do.  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 stem cells
that are derived from human  embryonic  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 nuclear  transfer  have
stimulated  significant debate in social and political arenas. We use stem cells
derived  through a process that uses as the starting  material  donated  embryos
created for in vitro  fertilization  procedures but no longer needed or suitable
for that use.  Many  research  institutions,  including  some of our  scientific
collaborators,  have  adopted  policies  regarding  the  ethical  use  of  human
embryonic  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  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,  but
relatively few federal grants have been made so far. The President's  Council on
Bioethics 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.  The  Council  issued a report  in July  2002  that
recommended "that the federal  government  undertake a thorough-going  review of
present  and  projected  practices  of human  embryo  research,  with the aim of
establishing appropriate institutions to advise and shape federal policy in this
arena." 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 somatic  cell
nuclear transfer technology  (sometimes called "somatic cell nuclear transfer").
We 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,  the use of nuclear  transfer to
produce  embryonic  stem cells  (referred  to as  "therapeutic  cloning")  could
provide   scientific   insights   that  would  help  us  advance  our  research.
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.

     The U.S. Congress has recently considered  legislation that would ban human
therapeutic cloning as well as reproductive cloning. Such a bill has been passed
by the House of Representatives, although not by the Senate, and


                                       7



many  legislators  reportedly  favor  such a ban.  The July  2002  report of the
President's  Council  on  Bioethics   recommended  a  four-year   moratorium  on
therapeutic  cloning.  If human therapeutic cloning is restricted or banned, 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  canceled  and our  business  could  be
significantly harmed.

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 the following risks:

    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.

     Protection of our  proprietary  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.  In particular,  legal principles for biotechnology patents
in the United  States and in other  countries  are  evolving,  and the extent to
which we will be able to obtain patent  coverage to protect our  technology,  or
enforce issued patents,  is uncertain.  Further,  our patents may be challenged,
invalidated or circumvented,  and our 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.

     Publication of discoveries in scientific or patent  literature tends to lag
behind  actual  discoveries  by at least several  months and  sometimes  several
years.  Therefore,  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 for discoveries  that we otherwise would consider  patentable and
that we consider to be extremely significant to our future success.

     Where several parties seek patent  protection for the same technology,  the
U.S. Patent Office may declare an interference  proceeding in order to ascertain
the party to which  the  patent  should  be  issued.  Patent  interferences  are
typically complex,  highly contested legal proceedings,  subject to appeal. They
are usually  expensive and  prolonged,  and can cause  significant  delay in the
issuance of patents.  Moreover,  parties that receive an adverse  decision in an
interference can lose important patent rights. Our pending patent  applications,
or our issued  patents,  may be drawn into  interference  proceedings  which may
delay or prevent the issuance of patents, or result in the loss of issued patent
rights.


                                       8



     The  interference  process can also be used to  challenge a patent that has
been  issued to another  party.  In 2001,  the U.S.  Patent  Office  granted our
request  for the  declaration  of an  interference  between  one of our  pending
applications  relating to nuclear  transfer  and an issued  patent,  held by the
University of Massachusetts.  We requested this interference in order to clarify
our patent  rights in  nuclear  transfer  technology.  In March  2002,  a second
interference  was  declared  involving  our  patent  application  and  a  patent
application  held by Infigen Inc. Both of these  interferences  are now ongoing.
Based on a  review  of  publicly  available  information,  we  believe  that the
technology  at issue in both of these  interferences  was invented  first at the
Roslin  Institute  and is  encompassed  within  our  nuclear  transfer  license.
However,  we do not have access to the other party's invention records,  and, as
in any legal proceeding, the outcome is uncertain.

     Outside of the U.S., certain  jurisdictions,  such as Europe and Australia,
permit  oppositions  to be filed  against the  granting of patents.  Because our
intent is to commercialize products  internationally,  securing both proprietary
protection and freedom to operate outside of the U.S. is important to us. We are
involved in both opposing the grant of patents to others through such opposition
proceedings, and in defending against oppositions filed by others.

     If interferences,  oppositions or other challenges to our patent rights are
not resolved promptly in our favor, our existing  business  relationships may be
jeopardized  and we  could  be  delayed  or  prevented  from  entering  into new
collaborations or from commercializing certain products,  which could materially
harm our business.

     Patent  litigation  may also be  necessary  to  enforce  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
litigation.  Patent  litigation can be extremely  expensive and  time-consuming,
even  if the  outcome  is  favorable  to us.  An  adverse  outcome  in a  patent
litigation or any other proceeding in a court or patent office could 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 technology platforms,  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  that 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 continue  our business  based on the  affected  technology
platform would be severely affected.

We 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.

We may be subject to  infringement  claims that are costly to defend,  and which
may limit our ability to use disputed technologies and prevents 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  the  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


                                       9


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 those  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.

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.

     Under agreements with  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 potential products will be delayed
if collaborators  fail to conduct these activities in a timely manner or at all.
In addition,  our collaborators  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 our  collaborators  breach  or
terminate their collaborative agreements with us, our business may be materially
harmed.

Our  reliance  on  the  research  activities  of  our  non-employee   scientific
consultants  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  consultants at
academic and other  institutions,  some of whom conduct research at our request.
These scientific  consultants 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
consultants  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 consultants are unable or refuse
to contribute to the development of any of our potential discoveries, our


                                       10



ability  to  generate   significant   advances  in  our  technologies   will  be
significantly harmed.

     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 who assist us in formulating  our
research and development and clinical 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.

     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


                                       11


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  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.

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 to not 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:


                                       12



    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  products are likely to be  expensive  to  manufacture,  and they may not be
profitable  if we are unable to  significantly  reduce the costs to  manufacture
them.

     Both GRN163 and our hESC-based products are likely to be significantly more
expensive to  manufacture  than most other drugs  currently on the market today.
Oligonucleotides  are large  molecules with complex  chemistry,  and the cost of
manufacturing even a short  oligonucleotide  like GRN163 is considerably greater
than the cost of making most  small-molecule  drugs.  Our present  manufacturing
processes are conducted at a relatively small scale and are at an early stage of
development.  We hope to  substantially  reduce  manufacturing  costs by process
improvements,  as well as through scale increases.  If we are not able to do so,
however,  and  depending  on the pricing of the  product,  the profit  margin on
GRN163 may be  significantly  less than that of most drugs on the market  today.
Similarly,  we currently  make  differentiated  cells from hESCs on a laboratory
scale,  at a high cost per unit of  measure.  The  cell-based  therapies  we are
developing  based on hESCs will probably  require large  quantities of cells. We
continue  to  develop  processes  to  scale  up  production  of the  cells  in a
cost-effective   way.  If  we  cannot  continue  to  improve  our  manufacturing
processes, we may not be able to charge a high enough price for our cell therapy
products,  even if they are  safe and  effective,  to make a  profit.  If we are
unable to realize significant profits from our potential


                                       13


products, our business would be materially harmed.

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.

     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 these
laws and  regulations  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  factors  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, 2003,  our stock has traded as high as $75.88 per share
and as low as $1.41 per share. Between September 1, 2002 and September 30, 2003,
the price has  ranged  between a high of $16.07 per share and a low of $1.41 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; or

    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, which then experience volatility in the market price of
their securities. Litigation brought


                                       14


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 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,  2003,  we had  33,349,939  shares of common stock
outstanding.  Of these  shares,  approximately  19,651,147  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,
approximately   15,174,543  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  approximately  4,476,604 of the remaining
shares may be resold pursuant to Rule 144 into the public markets.

Our undesignated  preferred stock may inhibit  potential  acquisition bids; this
may adversely affect the market price for 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
prospectus,  50,000  shares of  preferred  stock have been  designated  Series A
Junior  Participating  Preferred  Stock  and 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, 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 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  the  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.

number of shares of common stock owned  beneficially by the selling  stockholder

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  stockholder

stock  in  transactions  exempt  from  the  registration   requirements  of  the
Securities Act.  Information  concerning the selling stockholder may change from

                              PLAN OF DISTRIBUTION

     We are  registering  31,080  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    sales on the Nasdaq National Market;

     o    sales in the over-the-counter market;

     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    transactions   in  which   broker-dealers   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 the shares directly to market makers
acting as principals  and/or  broker-dealers  acting as agents for themselves or
their customers.  These  broker-dealers may receive  compensation in the form of
discounts,  concessions or commissions from the selling  stockholder  and/or the
purchasers  of shares for whom the  broker-dealers  may act as agents or to whom
they  sell  as  principal  or  both,  which  compensation  as  to  a  particular
broker-dealer  might be in excess of customary  commissions.  Market  makers and
block  purchasers  purchasing the shares will do so for their own account and at
their own risk. It is possible that the selling stockholder will attempt to sell
shares  of  common  stock  in  block  transactions  to  market  makers  or other
purchasers  at a price per share which may be below the then market  price.  The
selling  stockholder cannot assure that all or any of the shares offered in this
prospectus will be issued to, or sold by, the selling  stockholder.  The selling
stockholder and any brokers,  dealers or agents,  upon effecting the sale of any
of the shares offered in this prospectus,  may be deemed  "underwriters" as that
term is defined under the  Securities  Act or the Exchange Act, or the rules and
regulations under such acts.

     The  selling  stockholder,  alternatively,  may sell all or any part of the
shares offered in this prospectus through an underwriter.  To our knowledge, the
selling  stockholder  has not  entered  into any  agreement  with a  prospective
underwriter  and we cannot  assure you that any such  agreement  will be entered
into.  If the selling  stockholder  entered  into this type of an  agreement  or
agreements,  the relevant details will be set forth in a supplement or revisions
to this prospectus.

     The selling stockholder and any other persons  participating in the sale or
distribution  of the  shares  will be subject to  applicable  provisions  of the
Exchange Act and the rules and regulations  under such act,  including,  without
limitation,  Regulation M. These provisions may restrict certain  activities of,
and limit the timing of purchases and sales of any of the shares by, the selling
stockholder  or any other  person.  Furthermore,  under  Regulation  M,  persons
engaged in a  distribution  of securities  are  prohibited  from  simultaneously
engaging  in market  making and certain  other  activities  with  respect to the
securities  for a  specified  period of time  prior to the  commencement  of the


                                       18



distributions,  subject to  specified  exceptions  or  exemptions.  All of these
limitations may affect the marketability of the shares.

     The  selling  stockholder  also may sell all or a portion  of its shares in
open market  transactions  in reliance upon Rule 144 under the  Securities  Act,
provided they meet the criteria and conform to the requirements of Rule 144.

                                  LEGAL MATTERS

     Latham &  Watkins  LLP 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  Securities  and  Exchange  Commission  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(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a Delaware corporation may indemnify any person who was or
is a party or is  threatened  to be made a party to any  threatened,  pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative  (other than an action by or in the right of the  corporation)  by
reason of the fact that such person is or was a director,  officer,  employee or
agent of the  corporation or is or was serving at the request of the corporation
as a director,  officer, employee or agent of another corporation or enterprise,
against expenses,  judgments,  fines and amounts paid in settlement actually and
reasonably  incurred  by such person in  connection  with such  action,  suit or
proceeding if he acted in good faith and in a manner he  reasonably  believed to
be in or not opposed to the best interests of the corporation, and, with respect
to any criminal  action or  proceeding,  had no cause to believe his conduct was
unlawful.

     Section  145(b)  of the  DGCL  provides  that a  Delaware  corporation  may
indemnify  any person who was or is a party or is  threatened to be made a party
to any  threatened,  pending or  completed  action or suit by or in the right of
corporation  to procure a judgment  in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses actually
and  reasonably  incurred  by such  person in  connection  with the  defense  or
settlement of such action or suit if he or she acted under similar  standards to
those set forth above,  except that no indemnification may be made in respect to
any claim,  issue or matter as to which such person shall have been  adjudged to
be liable to the  corporation  unless and only to the  extent  that the court in
which  such  action  or suit  was  brought  shall  determine  that  despite  the
adjudication  of liability,  but in view of all the  circumstances  of the case,
such  person  is fairly  and  reasonably  entitled  to be  indemnified  for such
expenses which the court shall deem proper.

     Section 145 of the DGCL further  provides  that to the extent a director or
officer of a corporation has been successful in the defense of any action,  suit
or  proceeding  referred to in  subsection  (a) and (b) or in the defense of any
claim,  issue  or  matter  therein,  he shall be  indemnified  against  expenses
actually  and  reasonably  incurred  by  him  in  connection   therewith;   that
indemnification provided for by Section 145 shall not be deemed exclusive of any
other  rights  to which the  indemnified  party  may be  entitled;  and that the
corporation  may  purchase  and  maintain  insurance  on behalf of a director or
officer of the corporation  against any liability  asserted against such officer
or director  and  incurred by him or her in any such  capacity or arising out of
his or her status as such,  whether or not the corporation  would have the power
to indemnify him or her against such liabilities under Section 145.

     As  permitted  by  Section  102(b)(7)  of  the  DGCL,  our  Certificate  of
Incorporation  provides  that  a  director  shall  not  be  liable  to us or our
stockholders  for monetary  damages for breach of fiduciary  duty as a director.
However,  this provision does not eliminate or limit the liability of a director
for acts or  omissions  not in good  faith or for  breaching  his or her duty of
loyalty,  engaging in  intentional  misconduct  or knowingly  violating the law,
paying a  dividend  or  approving  a stock  repurchase  which  was  illegal,  or
obtaining an improper personal  benefit.  A provision of this type has no effect
on the availability of equitable remedies, such as injunction or rescission, for


                                       II-1


breach of  fiduciary  duty.  Our  Certificate  of  Incorporation  requires  that
directors  and  officers be  indemnified  to the  maximum  extent  permitted  by
Delaware law.

Item 16.   Exhibits.

         See Exhibit Index.

Item 17.   Undertakings.

     (a) 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:

     (i)  To  include  any  prospectus  required  by  Section  10(a)(3)  of  the
Securities Act of 1933;

     (ii) To reflect in the  prospectus  any facts or events  arising  after the
effective date of the registration  statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental change in the information set forth in this registration  statement.
Notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  and of the
estimated  maximum  offering  price may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule  424(b) if, in the  aggregate  the
changes in volume  and price  represent  no more than 20  percent  change in the
maximum  aggregate  offering price set forth in the "Calculation of Registration
Fee" table in the effective registration statement; and

     (iii) To  include  any  material  information  with  respect to the plan of
distribution  not  previously  disclosed in this  registration  statement or any
material change to such information in this registration statement;

     Provided,  however,  that  subparagraphs  (i) and (ii) do not  apply if the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs is contained in the periodic reports filed by the Registrant pursuant
to Section 13 or Section 15(d) of the  Securities  Exchange Act of 1934 that are
incorporated by reference in this registration statement.

         (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.

         (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) 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


                                      II-2


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.


                                      II-3


                                   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 October 1, 2003.

                                                                     Exhibit 4.1



                         COMMON STOCK PURCHASE AGREEMENT

     THIS COMMON STOCK PURCHASE AGREEMENT ("Agreement") is made and entered into
as of  September  25,  2003,  (the  "Effective  Date"),  by  and  between  GERON
CORPORATION,  a Delaware  corporation  having its principal place of business at
230  Constitution   Drive,   Menlo  Park,   California   94025  ("Geron"),   and
TRANSGENOMIC,  INC.,  a  Delaware  corporation  having  its  principal  place of
business at 12325 Emmet Street, Omaha, Nebraska 68164 ("Transgenomic").

     A.   Geron  and  Transgenomic  are  the  parties  to  that  certain  Supply
          Agreement  dated as of June 15,  2002 (the  "Supply  Agreement"),  and
          related Addendum Agreements  ("Addendum  Agreement") under which Geron
          has  agreed  to  purchase  certain  products  from   Transgenomic  and
          Transgenomic  has agreed to supply such products to Geron on the terms
          set forth therein.

     B.   Pursuant to Addendum  Agreement  No. 4  effective  September  22, 2003
          Geron may pay the purchase  price of products by delivery of shares of
          Geron's Common Stock (the "Shares").

THE PARTIES AGREE AS FOLLOWS:

     1.   Issuance of Shares; Adjustments.

     1.1  As payment of the First  Installment  specified in Addendum  Agreement
          No. 4, Geron will issue and deliver  certificates  for 31,080  Shares.
          Upon issuance and delivery of the  certificate(s)  for the Shares, all
          Shares shall be duly authorized and validly issued and represent fully
          paid shares of Geron's Common Stock.

     2. Closing; delivery.

     2.1  The consummation of the transaction  contemplated by this Agreement (a
          "Closing")  shall be held at such time and place as is mutually agreed
          upon  between  the  parties,  but in any event no later than three (3)
          business  days after the  Effective  Date of Addendum  Agreement No. 4
          (the  "Closing  Date").  At  the  Closing,   Geron  shall  deliver  to
          Transgenomic one or more certificates  representing all of the Shares,
          which  Shares  shall  be  issued  in the name of  Transgenomic  or its
          designee and in such denominations as Transgenomic shall specify.

     2.2  Geron's  obligations  to issue and  deliver  the stock  certificate(s)
          representing  the  Shares  to  Transgenomic  at the  Closing  shall be
          subject to the following conditions, which may be waived by Geron:

          2.2.1 the covenants and obligations  that  Transgenomic is required to
               perform or to comply with pursuant to this Agreement, at or prior
               to the Closing,  must have been duly  performed and complied with
               in all material respects; and

          2.2.2 the representations  and warranties made by Transgenomic  herein
               shall be true and  correct  in all  material  respects  as of the
               Closing Date.

     2.3  Transgenomic's   obligation   to   accept   delivery   of  the   stock
          certificate(s) representing the Shares at the Closing shall be subject
          to the following conditions, any one or more of which may be waived by
          Transgenomic:

                                       1




          2.3.1 the covenants and obligations  that Geron is required to perform
               or to comply with pursuant to this Agreement,  at or prior to the
               Closing,  must have been duly  performed and complied with in all
               material respects;

          2.3.2 Geron  shall   have   available   under   its   Certificate   of
               Incorporation  sufficient  authorized  shares of Common  Stock to
               issue the Shares to Transgenomic; and

          2.3.3 the representation and warranties made by the Geron herein shall
               be true and  correct in all  material  respects as of any Closing
               Date.

     3. Restrictions on Resale of Shares.

     3.1  Legends. Transgenomic understands and acknowledges that the Shares are
          not registered under the Securities Act of 1933 (the "Act"),  and that
          under the Act and other  applicable laws  Transgenomic may be required
          to hold such  Shares  for an  indefinite  period of time.  Each  stock
          certificate representing Shares shall bear the following legends:

          "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). ANY
          TRANSFER OF SUCH SECURITIES SHALL BE INVALID UNLESS A
          REGISTRATION STATEMENT UNDER THE ACT IS IN EFFECT AS TO SUCH
          TRANSFER OR, IN THE OPINION OF COUNSEL REASONABLY ACCEPTABLE
          TO GERON, SUCH REGISTRATION IS UNNECESSARY FOR SUCH TRANSFER
          TO COMPLY WITH THE ACT. THE SECURITIES REPRESENTED HEREBY ARE
          SUBJECT TO THE TERMS OF THE COMMON STOCK PURCHASE AGREEMENT,
          DATED SEPTEMBER 22, 2003. A COPY OF THE AGREEMENT CAN BE
          OBTAINED FROM THE SECRETARY OF GERON."

     3.2  Limits on Sales. Transgenomic agrees that if it decides to resell some
          or all of the  Shares,  it will do so  only in an  appropriate  manner
          based upon whether the shares are registered or  unregistered,  ie. on
          the Nasdaq  National  Market or in a Rule 144A compliant  transaction.
          Subject to the foregoing restrictions, Transgenomic may sell or resell
          the Shares in any lot size, or at any volume, desired by Transgenomic.


                                        2



     4. REGISTRATION RIGHTS

     4.1  Geron agrees to file with the Securities and Exchange  Commission (the
          "Commission"),  as promptly as practicable and in any event within ten
          (10) business days after the Closing  Date, a  registration  statement
          under  the Act (the  "Registration  Statement"),  on Form S-3 or other
          appropriate form, so as to permit a  non-underwritten  public offering
          and resale of the Shares under the Act by  Transgenomic.  Geron agrees
          to diligently  pursue  making the  Registration  Statement  effective.
          Geron  will  notify   Transgenomic   of  the   effectiveness   of  the
          Registration Statement within one (1) business day of receiving notice
          from the Commission.

     4.2  Geron will maintain the Registration  Statement and any post-effective
          amendment  thereto filed under this Section 4 effective  under the Act
          until the earliest of (i) the date that none of the Shares  covered by
          such Registration Statement are issued and outstanding,  (ii) the date
          that all of the Shares have been sold  pursuant  to such  Registration
          Statement,  (iii) the date Transgenomic receives an opinion of counsel
          to  Geron,   which   counsel   shall  be   reasonably   acceptable  to
          Transgenomic, that the Shares may be sold under the provisions of Rule
          144  without  limitation  as to volume,  (iv) the date that all Shares
          have been  otherwise  transferred to persons who may trade such shares
          without  restriction  under the Act,  and Geron  has  delivered  a new
          certificate  or other  evidence of ownership for such  securities  not
          bearing a restrictive  legend,  or (v) the date all Shares may be sold
          at any time, without volume or manner of sale limitations  pursuant to
          Rule 144(k) or any similar  provision  then in effect under the Act in
          the opinion of counsel to Geron,  which  counsel  shall be  reasonably
          acceptable to Transgenomic.

     4.3  Geron, at its expense,  shall furnish to Transgenomic  with respect to
          the Shares registered under the Registration Statement such reasonable
          number of  copies  of the  Registration  Statement,  prospectuses  and
          preliminary  prospectuses in conformity  with the  requirements of the
          Act and such other documents as Transgenomic  may reasonably  request,
          in order to facilitate the public sale or other  disposition of all or
          any of  the  Shares  by  Transgenomic,  provided,  however,  that  the
          obligation of Geron to deliver copies of  prospectuses  or preliminary
          prospectuses to Transgenomic  shall be subject to the receipt by Geron
          of reasonable  assurances from  Transgenomic  that  Transgenomic  will
          comply  with the  applicable  provisions  of the Act and of such other
          securities or blue sky laws as may be  applicable  in connection  with
          any use of such prospectuses or preliminary prospectuses.

     4.4  All fees,  disbursements and out-of-pocket expenses and costs incurred
          by  Geron  in  connection  with  the  preparation  and  filing  of the
          Registration  Statement  under  Section  4.1  and  in  complying  with
          applicable   securities   and  Blue  Sky  laws   (including,   without
          limitation,  all  attorneys'  fees of Geron)  shall be borne by Geron.
          Transgenomic   shall   bear  the  cost  of  fees   and   expenses   of
          Transgenomic's counsel.

     4.5  Geron will advise Transgenomic  promptly after it shall receive notice
          or  obtain  knowledge  of  the  issuance  of  any  stop  order  by the
          Commission   delaying  or   suspending   the   effectiveness   of  the
          Registration Statement or of the initiation of any proceeding for that
          purpose,  and Geron will use its  commercially  reasonable  efforts to
          prevent the issuance of any stop order or to obtain its  withdrawal at
          the earliest possible moment if such stop order should be issued.

                                       3




     4.6  With a view to making  available to Transgenomic  the benefits of Rule
          144 (or its  successor  rule) and any other rule or  regulation of the
          Commission that may at the time permit Transgenomic to sell the Shares
          to the public without registration, Geron covenants and agrees to: (i)
          make  and keep  public  information  available,  as  those  terms  are
          understood  and  defined in Rule 144,  until the  earliest of (A) such
          date as all of the Shares may be resold pursuant to Rule 144(k) or any
          other  rule of  similar  effect or (B) such date as all of the  Shares
          shall have been resold;  and (ii) file with the Commission in a timely
          manner all reports and other documents required of Geron under the Act
          and under the Exchange Act of 1934, as amended.

     4.7  Transgenomic  will  cooperate with Geron in all respects in connection
          with  this  Agreement,  including  timely  supplying  all  information
          reasonably  requested by Geron (which  shall  include all  information
          regarding  Transgenomic  and  proposed  manner  of sale of the  Shares
          required to be disclosed in any Registration  Statement) and executing
          and returning all documents  reasonably  requested in connection  with
          the  registration  and  sale  of the  Shares  and  entering  into  and
          performing their obligations under any underwriting  agreement, if the
          offering is an  underwritten  offering,  in usual and customary  form,
          with the managing  underwriter or  underwriters  of such  underwritten
          offering.  Nothing in this Agreement  shall obligate  Transgenomic  to
          consent to be named as an underwriter in any Registration Statement.

     5.   Indemnification.

     5.1  Geron agrees to indemnify  and hold  harmless  Transgenomic  (and each
          person,  if any,  who  controls  Transgenomic  within  the  meaning of
          Section 15 of the Act, and each officer and director of  Transgenomic)
          against any and all losses, claims, damages or liabilities (or actions
          or  proceedings  in respect  thereof),  joint or several,  directly or
          indirectly  based upon or arising out of (i) any untrue  statement  or
          alleged  untrue  statement  of  any  material  fact  contained  in the
          Registration Statement,  any preliminary prospectus,  final prospectus
          or summary prospectus contained therein or used in connection with the
          offering of the Shares,  or any  amendment or supplement  thereto,  or
          (ii)  any  omission  or  alleged  omission  to state a  material  fact
          required  to be stated  therein or  necessary  to make the  statements
          therein not misleading; and Geron will reimburse each such indemnified
          party for any legal or any other expenses  reasonably incurred by them
          in connection with investigating, preparing, pursuing or defending any
          such loss,  claim,  damage,  liability,  action or proceeding,  except
          insofar as any such loss, claim, damage, liability, action, proceeding
          or expense (A) arises out of or is based upon an untrue  statement  or
          alleged untrue  statement or omission or alleged  omission made in the
          Registration  Statement,   any  such  preliminary  prospectus,   final
          prospectus,  summary  prospectus,  amendment or supplement in reliance
          upon and in conformity with written information  furnished to Geron by
          Transgenomic or such other person expressly for use in the preparation
          thereof,  (B) the failure of Transgenomic to comply with its covenants
          and  agreements  contained  in Sections 7.1 or 7.5.2 hereof or (C) any
          misstatement  or omission in any  prospectus  that is corrected in any
          subsequent  prospectus that was delivered to Transgenomic prior to the
          pertinent sale or sales by  Transgenomic.  Such indemnity shall remain
          in full force and effect, regardless of any investigation made by such
          indemnified  party and shall  survive  the  transfer  of the Shares by
          Transgenomic.

                                       4




     5.2  Transgenomic  agrees to indemnify  and hold  harmless  Geron (and each
          person, if any, who controls Geron within the meaning of Section 15 of
          the Act,  each officer of Geron who signs the  Registration  Statement
          and each director of Geron) from and against losses,  claims,  damages
          or liabilities (or actions or proceedings in respect  thereof),  joint
          or several,  directly or indirectly  based upon or arising out of, (i)
          any  failure  of   Transgenomic  to  comply  with  the  covenants  and
          agreements  contained  in  Sections  7.1 and 7.5.2  hereof or (ii) any
          untrue  statement of a material  fact  contained  in the  Registration
          Statement or any omission of a material  fact required to be stated in
          the  Registration   Statement  or  necessary  in  order  to  make  the
          statements in the Registration Statement not misleading if such untrue
          statement or omission was made in reliance upon and in conformity with
          written  information  furnished to Geron by on behalf of  Transgenomic
          specifically  for use in  preparation of the  Registration  Statement;
          provided,  however,  that Transgenomic shall not be liable in any such
          case for (A) any untrue  statement  or  omission  in the  Registration
          Statement,  prospectus,  or other such  document  which  statement  is
          corrected  by  Transgenomic  and  delivered to Geron prior to the sale
          from which such loss occurred, (B) any untrue statement or omission in
          any prospectus  which is corrected by  Transgenomic  in any subsequent
          prospectus, or supplement or amendment thereto, and delivered to Geron
          prior to the sale or sales from which a loss or  liability  arose,  or
          (C) any  failure  by Geron to  fulfill  any of its  obligations  under
          Section 5.1 hereof.

     5.3  Promptly  after  receipt  by any  indemnified  person of a notice of a
          claim or the beginning of any action in respect of which  indemnity is
          to be sought against an  indemnifying  person pursuant to this Section
          5, such  indemnified  person shall notify the  indemnifying  person in
          writing of such claim or of the  commencement of such action,  but the
          omission to so notify the indemnifying  party will not relieve it from
          any liability  which it may have to any  indemnified  party under this
          Section 5 (except  to the extent  that such  omission  materially  and
          adversely  affects  the  indemnifying  party's  ability to define such
          action) or from any  liability  otherwise  than under this  Section 5.
          Subject to the provisions  hereinafter stated, in case any such action
          shall be  brought  against an  indemnified  person,  the  indemnifying
          person shall be entitled to  participate  therein,  and, to the extent
          that it shall elect by written  notice  delivered  to the  indemnified
          party  promptly  after  receiving  the  aforesaid   notice  from  such
          indemnified  party,  shall be entitled to assume the defense  thereof,
          with counsel reasonably satisfactory to such indemnified person. After
          notice from the indemnifying  person to such indemnified person of its
          election to assume the defense thereof, such indemnifying person shall
          not be  liable  to  such  indemnified  person  for any  legal  expense
          subsequently  incurred by such  indemnified  person in connection with
          the defense thereof, provided,  however, that if there exists or shall
          exist a conflict of  interest  that would make  inappropriate,  in the
          reasonable opinion of counsel to the indemnified  person, for the same
          counsel to represent both the indemnified person and such indemnifying
          person or any affiliate or associate  thereof,  the indemnified person
          shall be  entitled  to retain its own  counsel at the  expense of such
          indemnifying person;  provided,  however,  that no indemnifying person
          shall  be  responsible  for the  fees  and  expenses  of more  than on
          separate  counsel  (together with  appropriate  local counsel) for all
          indemnified  parties.  In no event  shall any  indemnifying  person be
          liable in  respect to any  amounts  paid in  settlement  of any action
          unless the  indemnifying  person shall have approved the terms of such
          settlement.  No indemnifying  person shall,  without the prior written
          consent  of the  indemnified  person,  effect  any  settlement  of any
          pending or threatened  proceeding in respect of which any  indemnified
          person is or could  have been a party and  indemnification  could have
          been  sought  hereunder  by  such  indemnified  person,   unless  such
          settlement  includes  an  unconditional  release  of such  indemnified
          person from all  liability  on claims  that are the subject  matter of
          such proceeding.

     5.4  The provisions of this Section 5 shall survive the termination of this
          Agreement.

     6. Representations and acknowledgement of Geron.

        Geron hereby represents, warrants and covenants to Transgenomic as
        follow:

     6.1  Organization, Good Standing and Qualification.  Geron is a corporation
          duly organized,  validly  existing and in good standing under the laws
          of the State of Delaware  and has all  requisite  corporate  power and
          authority to carry on its business as now  conducted  and as presently
          proposed to be conducted. Geron is duly qualified to transact business
          and is in good standing as a foreign  corporation in each jurisdiction
          in which the  failure  to so qualify  would  have a  material  adverse
          effect on its business or properties.

     6.2  Authorization.  All  corporate  action  on the party of  Company,  its
          officers,  directors and stockholders necessary for the authorization,
          execution  and  delivery of this  Agreement,  the  performance  of all
          obligations of Company hereunder and the  authorization,  issuance and
          delivery  of the Shares  has been taken or will be taken  prior to the
          Closing,  and  this  Agreement,   when  executed  and  delivered  will
          constitute valid and legally binding obligations of Geron, enforceable
          against  Geron in  accordance  with their terms,  except as limited by
          applicable   bankruptcy,   insolvency,   reorganization,   moratorium,
          fraudulent  conveyance and other laws of general application affecting
          enforcement  of  creditors'  rights  generally,  as  limited  by  laws
          relating  to the  availability  of  specific  performance,  injunctive
          relief or other equitable remedies.

     6.3  Valid  Issuance of Common  Stock.  The Shares,  when issued,  sold and
          delivered in  accordance  with the terms hereof for the  consideration
          expressed  herein,  will be duly and  validly  authorized  and issued,
          fully paid and  nonassessable  and free of  restrictions  on  transfer
          other  than   restrictions   on  transfer  under  this  Agreement  and
          applicable state and federal securities laws.

     6.4  Legal Proceedings and Orders. There is no action, suit,  proceeding or
          investigation  pending or threatened  against Geron that questions the
          validity  of this  Agreement  or the right of Geron to enter into this
          Agreement or to consummate this transactions  contemplated hereby, nor
          is Geron aware of any basis for any of the forgoing.  Geron is neither
          a party nor subject to the provisions of any order, writ,  injunction,
          judgment   or   decree   of  any   court  or   government   agency  or
          instrumentality  that would  affect the ability of Geron to enter into
          this Agreement or to consummate the transactions contemplated hereby.

     7. Representations and Acknowledgments of Transgenomic.

    Transgenomic hereby represents, warrants, acknowledges and agrees that:

     7.1  Investment.  Transgenomic  is acquiring the Shares for  Transgenomic's
          own  account,  and not directly or  indirectly  for the account of any
          other person.  Transgenomic is acquiring the Shares for investment and
          not  with  a  view  to  distribution  or  resale  thereof,  except  in
          compliance  with  the Act  and any  applicable  state  law  regulating
          securities.

                                       6




     7.2  Access  to  Information.  Transgenomic  has  consulted  with  its  own
          attorney, accountant, or investment advisor as Transgenomic has deemed
          advisable  with  respect  to the  investment  and has  determined  its
          suitability for Transgenomic.  Transgenomic has had the opportunity to
          ask questions of, and to receive answers from,  appropriate  executive
          officers  of Geron  with  respect to the terms and  conditions  of the
          transactions  contemplated  hereby and with  respect to the  business,
          affairs,  financial  condition  and  results of  operations  of Geron.
          Transgenomic has had access to such financial and other information as
          is  necessary  in  order  for  Transgenomic  to make a fully  informed
          decision as to investment  in Geron,  and has had the  opportunity  to
          obtain  any  additional  information  necessary  to verify any of such
          information  to  which  Transgenomic  has  had  access.   Transgenomic
          acknowledges  that neither Geron nor any of its  officers,  directors,
          employees,  agents,   representatives,   or  advisors  have  made  any
          representation  or warranty  other than those  specifically  expressed
          herein.

     7.3  Business and Financial Expertise.  Transgenomic further represents and
          warrants  that it has such  business or  financial  expertise as to be
          able to evaluate its investment in Geron and purchase of the Shares.

     7.4  Speculative Investment.  Transgenomic acknowledges that the investment
          in Geron represented by the Shares is highly speculative in nature and
          is subject to a high  degree of risk of loss in whole or in part;  the
          amount of such investment is within  Transgenomic's risk capital means
          and is not so great in  relation  to  Transgenomic's  total  financial
          resources  as  would  jeopardize  the  personal   financial  needs  of
          Transgenomic  in the event  such  investment  were lost in whole or in
          part.

     7.5  Unregistered Securities. Transgenomic acknowledges that:

          7.5.1 Transgenomic must bear the economic  risk of  investment  for an
               indefinite period  of time  because  the  Shares  have  not been
               registered under the Act and  therefore  cannot  and will not be
               sold unless they are subsequently  registered under the Act or an
               exemption from such registration is available.  Geron has made no
               agreements,  covenants or undertakings whatsoever to register any
               of the  Shares  under the Act,  except as  provided  in Section 4
               above. Geron has made no representations, warranties or covenants
               whatsoever as to whether any exemption  from the Act,  including,
               without  limitation,  any  exemption for limited sales in routine
               brokers'  transactions  pursuant to Rule 144 under the Act,  will
               become available and any such exemption  pursuant to Rule 144, if
               available  at all,  will not be  available  unless:  (i) a public
               trading  market then exists in Geron's  common stock,  (ii) Geron
               has complied with the  information  requirements of Rule 144, and
               (iii)  all  other  terms  and  conditions  of Rule 144 have  been
               satisfied.

          7.5.2 Transfer of the Shares  has not been  registered  or  qualified
               under  any  applicable  state  law  regulating   securities  and,
               therefore, the Shares cannot and will not be sold unless they are
               subsequently  registered  or  qualified  under any such act or an
               exemption  therefrom is available.  Geron has made no agreements,
               covenants or  undertakings  whatsoever to register or qualify any
               of  the   Shares   under  any  such   act.   Geron  has  made  no
               representations, warranties or covenants whatsoever as to whether
               any exemption from any such act will become available.

          7.5.3 Transgenomic  hereby   certifies   that  it  is  an  "Accredited
               Investor" as that term is defined in Rule 501 under the Act.

     8.  Tax Advice. Transgenomic acknowledges that Transgenomic has not relied
         and will not rely upon Geron or Geron's counsel with respect to any tax
         consequences related to the ownership, purchase, or disposition of the
         Shares. Transgenomic assumes full responsibility for all such
         consequences and for the preparation and filing of all tax returns and
         elections which may or must be filed in connection with the Shares.

                                       7

         and unenforceable provision was not contained herein.

  Re: Registration of 31,080 shares of common stock, par value $0.001 per share,
      of Geron Corporation, pursuant to a Registration Statement on Form S-3

Ladies and Gentlemen:

     In connection  with the  registration  for resale of an aggregate of 31,080
shares of common  stock,  par value $0.001 per share,  of Geron  Corporation,  a
Delaware  corporation  (the  "Company"),  under the  Securities  Act of 1933, as
amended,  on Form S-3 filed  with the  Securities  and  Exchange  Commission  on
October 1, 2003 (the "Registration  Statement"),  you have requested our opinion
with respect to the matters set forth below.  The shares  being  registered  for
resale  include an aggregate of 31,080  shares of common stock which were issued
and sold to  Transgenomic,  Inc.  ("Transgenomic")  pursuant  to a Common  Stock
Purchase Agreement dated as of September 22, 2003 by and between the Company and
Transgenomic (the "Shares").

     In  our  capacity  as  your  special   counsel  in  connection   with  such
registration,  we are  familiar  with the  proceedings  taken by the  Company in
connection with the authorization  and issuance of the Shares.  In addition,  we
have made such  legal and  factual  examinations  and  inquiries,  including  an
examination  of originals or copies  certified  or otherwise  identified  to our
satisfaction of such documents,  corporate  records and instruments,  as we have
deemed necessary or appropriate for purposes of this opinion.

     In our examination,  we have assumed the genuineness of all signatures, the
authenticity of all documents  submitted to us as originals,  and the conformity
to authentic original  documents of all documents  submitted to us as copies. As
to facts material to the opinions,  statements and assumptions expressed herein,
we  have,  with  your  consent,  relied  upon  oral or  written  statements  and
representations of officers and other representatives of the Company and others.
In addition,  we have obtained and relied upon such  certificates and assurances
from public officials as we have deemed necessary.

     We are opining herein as to the effect on the subject  transaction  only of
the General Corporation Law of the State of Delaware,  and we express no opinion
with respect to the applicability thereto, or the effect thereon, of the laws of
any  jurisdiction or any other laws or as to any matters of municipal law or the
laws of any local agencies within any state.

     Subject to the  foregoing,  it is our opinion  that, as of the date hereof,
the Shares  have been duly  authorized  and are validly  issued,  fully paid and
nonassessable.

     We consent to your  filing this  opinion as an exhibit to the  Registration
Statement and to the reference to our firm  contained  under the heading  "Legal
Matters."

                                           Very truly yours,
