ITEM 1. BUSINESS

BACKGROUND

     Neurocrine  Biosciences,  Inc. is a leading neuroscience company focused on
the  discovery  and  development  of novel  therapeutics  for  neuropsychiatric,
neuroinflammatory  and neurodegenerative  diseases and disorders.  The Company's
neuroscience,  endocrine and immunology  disciplines provide a unique biological
understanding of the molecular  interaction between central nervous,  immune and
endocrine systems for the development of therapeutic  interventions for anxiety,
depression,  Alzheimer's  disease,  insomnia,  stroke,  glioblastoma,   multiple
sclerosis, obesity and diabetes.

     The  following   Business  section  contains   forward-looking   statements
concerning the continuation of the Company's strategic alliances and the receipt
of payments thereunder, the identification of drug targets and selection of lead
compounds for clinical  development,  the commencement and successful conclusion
of clinical  trials,  the receipt of  regulatory  approvals,  and the  potential
development  of future  commercial  products.  Such  forward-looking  statements
necessarily involve risks and uncertainties.  The Company's actual results could
differ materially from those anticipated in these forward-looking  statements as
a result of  certain  factors,  including,  without  limitation,  that  research
funding and development will continue under the Company's  collaborations,  that
research  and   development   candidates  will   successfully   proceed  through
pre-clinical and early stage clinical trials,  that development  candidates will
prove  effective for  treatment in humans in later stage  clinical  trials,  the
timely  receipt  of  regulatory   clearances   required  for  clinical  testing,
manufacturing  and  marketing  of  products,  the  potential  adverse  impact of
competitive  technologies,  products,  and intellectual property rights of third
parties,  and the failure to achieve product  development and  commercialization
goals.  Actual results and the timing of certain events could differ  materially
from those indicated in the forward-looking  statements as a result of these and
other factors. See "Risk Factors."

     Neurocrine  currently  has  five  programs  in  clinical  development.  The
Company's  CRF  receptor  antagonist  project is  currently in Phase II clinical
development with its partner,  Janssen  Pharmaceutica,  for  anxiety/depression.
Neurocrine  and its partner,  Novartis  Pharmaceuticals,  are  conducting  their
second Phase II clinical trial with  Neurocrine's  Altered  Peptide Ligand (APL)
compound in patients with multiple  sclerosis.  Neurocrine is conducting a Phase
I/II trial with for its IL-4  Fusion  Toxin for  glioblastoma  (malignant  brain
tumors).  The Company has also  completed a Phase Ib clinical  trial in insomnia
with a GABA receptor subtype agonist and recently  announced that it commenced a
Phase I safety and dose escalating  clinical study with an APL compound for Type
I Diabetic patients.

Neurocrine's Research and Development Programs


Corticotropin Releasing Factor ("CRF")

     Corticotropin releasing factor, the central regulator of the body's overall
response to stress, affects multiple systems by functioning both as an endocrine
factor  and a  neurotransmitter.  CRF acts as a hormone at the  pituitary  gland
causing the secretion of the steroid  cortisol from the adrenal glands resulting
in a number of metabolic  effects,  including  suppression of the immune system.
CRF also functions as a neurotransmitter  in the brain and plays a critical role
in  coordinating  psychological  and  behavioral  responses  to  stress  such as
increased  heart rate,  anxiety,  arousal and reduced  appetite.  In addition to
neuroendocrine and neurotransmitter  roles,  accumulating evidence suggests that
CRF may also integrate actions between the immune and central nervous systems in
response to physiological and psychological stressors.

     The body has  several  mechanisms  to  regulate  the  effects  of CRF.  The
Company's  cloning of human CRF receptors and binding proteins suggests that the
diverse  functions of CRF are mediated through distinct  receptor subtypes which
are differentially distributed in specific brain areas and in tissues outside of
the central  nervous  system.  These  targets may offer a mechanism  to modulate
specific  actions of CRF without  affecting  the broad range of its  activities.
There are  several  diseases  and  disorders  such as  anxiety,  depression  and
substance abuse in which CRF levels are increased.  The  deleterious  effects of
high levels of CRF may be  countered  by the  administration  of  selective  CRF
receptor antagonists.

Anxiety

     Anxiety is among the most commonly  observed group of CNS disorders,  which
includes  phobias  or  irrational  fears,  panic  attacks,  obsessive-compulsive
disorders  and other  fear and  tension  syndromes.  Estimates  by the  National
Institute of Mental  Health  suggest that the most commonly  diagnosed  forms of
anxiety  disorders  may  affect  10% of the  United  States  population.  Of the
pharmaceutical  agents that are currently  marketed for the treatment of anxiety
disorders,  a class of compounds  known as the  benzodiazepines,  which includes
Valium,  is the most  frequently  prescribed.  In  spite  of  their  therapeutic
efficacy,  several side effects limit the utility of these  anti-anxiety  drugs.
Most problematic among these are drowsiness, ataxia (the inability to stand up),
amnesia,  drug  dependency and withdrawal  reactions  following the cessation of
therapy.

     Neurocrine  is  developing  a  new  class  of  therapeutics   that  targets
stress-induced   anxiety.   In  view  of  the   evidence   implicating   CRF  in
anxiety-related disorders,  Neurocrine is developing small molecule CRF receptor
antagonists as anti-anxiety  agents that block the effects of  overproduction of
CRF. The Company  believes that these  compounds  represent a class of molecules
based on a novel  mechanism of action that may offer the advantage of being more
selective,  thereby providing  increased efficacy with reduced side effects.  In
animal studies used to evaluate  anti-anxiety drugs,  Neurocrine scientists have
demonstrated  the efficacy of its clinical  compound  candidates  following oral
administration without evidence of apparent side effects. Neurocrine's corporate
partner,  Janssen,  selected a CRF-1  receptor  antagonist  drug  candidate  for
preclinical  testing in 1996 and commenced and completed Phase I clinical trials
on the  compound  in late  1998.  Results in animal  models of  anxiety  are not
necessary  predictive of efficacy in human  clinical  trials and there can be no
assurance that these compounds will demonstrate  clinical efficacy in humans. In
addition,  no assurance can be given that Janssen will successfully initiate and
complete  Phase II clinical  testing or progress to later  clinical  trials in a
timely manner.



Depression

     Depression is one of a group of  neuropsychiatric  disorders  that includes
extreme  feelings  of  elation  and  despair,  loss  of body  weight,  decreased
aggressiveness  and  sexual  behavior,  and loss of  sleep.  This  condition  is
believed  to result  from a  combination  of  environmental  factors,  including
stress,  as  well  as  an  individual's  biochemical  vulnerability,   which  is
genetically  predetermined.  The  biochemical  basis of depression is thought to
involve   elevated   secretion  of  CRF  and  abnormally  low  levels  of  other
neurotransmitters  in the  brain  such as  serotonin.  Clinical  depression  was
reported to affect 6% of the population or approximately 25 million  individuals
in the  United  States  in 1998.  Current  antidepressant  therapies,  including
Prozac,  increase the levels of  serotonin  and several  other  chemicals in the
brain. Because these drugs affect a wide range of  neurotransmitters,  they have
been associated with a number of side effects. While newer, more selective drugs
offer  some  safety  improvement,  side  effects  remain  problematic.   Another
limitation to most existing antidepressant therapies is slow onset of action.

     Neurocrine  and  its  corporate   partner  are  developing  small  molecule
therapeutics to block the effects of  overproduction of CRF for the treatment of
depression.  The Company has developed  several distinct  chemical series of CRF
receptor antagonists.  Janssen selected a drug candidate in 1996 for preclinical
testing and commenced  Phase I clinical  trials on the compound in late 1997 and
completed  these in 1998. In late 1998 a Phase II open label trial was initiated
in patients  with major  depression.  Results from this trial are expected to be
available in second half of 1999.  No  assurance  can be given that Janssen will
successfully  complete  Phase II clinical  testing of this candidate or that the
Phase II data will support  continuation of the program and additional  clinical
trials.

Stroke

     Stroke is an acute  neurologic  event  caused by  blockage  or  rupture  of
vessels,  which supply blood to the brain leading to nerve cell death.  Neuronal
damage progresses over a period of four to six hours.  According to the National
Institutes  of  Health  ("NIH")   estimates,   approximately   500,000  patients
experience a stroke in the United States each year, with an approximately  equal
incidence  in the rest of the  world.  Stroke  results in an  estimated  150,000
fatalities each year,  making it the leading cause of death behind heart disease
and cancer, and an estimated  additional 150,000 stroke victims suffer permanent
neurological damage.  Survivors of stroke are at significantly increased risk of
suffering  another  episode.  Current  treatments for stroke consist of surgery,
steroid therapy and  anti-platelet  therapy.  These treatments may help increase
blood flow but do not affect the  secondary  mechanisms  which  cause nerve cell
death.

     Neurocrine believes its CRF receptor antagonist program may have utility in
the treatment of stroke. Preliminary experiments in animal models of stroke show
enhancement  of  neuronal  survival  following  treatment  with  a CRF  receptor
antagonist.  Results  obtained  in animals  are not  necessarily  predictive  of
results obtained in humans,  and no assurance can be given that the Company will
successfully complete pre-clinical development of CRF antagonist drug candidates
appropriate  for stroke and enter into or complete  clinical  trials in a timely
manner, if at all.

Altered Peptide Ligands

     In North  America,  five percent of adults,  more than  two-thirds  of them
women, suffer from autoimmune diseases (including multiple sclerosis, rheumatoid
arthritis, Type I diabetes, systemic lupus erythematosus,  and thyroiditis). The
body's immune system employs  highly  specific T cells that recognize and attack
foreign antigens that invade the body. Occasionally,  certain T cells arise that
inappropriately  recognize  the body's own tissues as foreign.  While  virtually
every  individual  possesses these  self-reactive T cells, in only a fraction of
these people do the immune cells  actually  attack  healthy  tissue and cause an
autoimmune disease. In a healthy individual, the activity of these self-reactive
T  cells  is held in  check  by  other T  cells  that  regulate  their  function
(regulatory T cells).  If a defect in regulatory T cell function occurs,  or the
environment  favors the activity of self-reactive T cells, an autoimmune disease
results.  While it is not clear  what  triggers  the  immune  attack,  a current
hypothesis  suggests that people who are  genetically  predisposed to autoimmune
diseases  come in contact with certain  infectious  viruses or bacteria.  In the
process of controlling  the  infection,  the immune system targets an antigen on
the infectious  agent that resembles a  self-antigen.  These cells then begin to
attack  self-tissue,  resulting  in  autoimmune  disease.  Thus,  a  failure  in
regulation of the immune system at the level of dysfunctional regulatory T cells
predisposes an individual to autoimmune disease. Current reasoning suggests that
the   development  of  immune   specific  drugs  that  suppress  the  action  of
self-reactive  T cells and/or  restore the function of  regulatory T cells might
prove  advantageous  for  the  prevention/cure  or  treatment  of an  autoimmune
disease.

     The T cells involved in the autoimmune disease achieve specificity in their
various  functions  via their cell  surface  molecules  known as T cell  antigen
receptors ("TCR").  Each T cell expresses its own specific TCR on its surface. T
cells  recognize  antigens,  whether foreign or self-derived in the context of a
MHC molecule.  This then represents the ligand that hooks up and binds to such a
TCR. In this manner,  a peptide  fragment can send a signal to the T cell via an
antigen-specific  TCR that binds  specifically to this antigen.  After receiving
this  signal  through  its TCR,  the T cell will  divide,  proliferate,  secrete
cytokines and/or destroy healthy cells.

     If the structure of such a peptide fragment is altered,  such that it binds
to its specific TCR with much less affinity, this altered peptide ligand ("APL")
sends an incomplete  signal to the T cell. This incomplete or altered signal can
trick a T cell and prevent it from dividing, proliferating,  secreting cytokines
and/or  destroying  normal  cells.  Indeed,  if such an APL can be  designed  to
prevent  "killer" T cells from  destroying  healthy cells,  it would represent a
very  useful  antigen-specific  therapy  to prevent  the onset of an  autoimmune
disease.

Multiple Sclerosis ("MS")

     Multiple  sclerosis is a chronic immune mediated  disease  characterized by
recurrent attacks of neurologic dysfunction due to damage in the central nervous
system ("CNS").  The classic clinical features of MS include impaired vision and
weakness or  paralysis  of one or more limbs.  Patients  develop a slow,  steady
deterioration  of neurologic  function over an average duration of approximately
30 years. The cause of MS is unknown but immunologic or infectious  factors have
been implicated. According to the National Multiple Sclerosis Society, there are
an estimated  350,000  cases of multiple  sclerosis in the United  States and an
equal number of patients in Europe with approximately 20,000 new cases diagnosed
worldwide each year.  Currently  available  treatments for MS offer only limited
efficacy.  Steroids have been used to reduce the severity of acute flare-ups and
speed recovery.  Experimental  therapy with other  immunosuppressive  agents has
shown limited success.  Betaseron (a form of beta-interferon)  has been shown to
delay the onset of flare-ups  of the symptoms in patients and has been  approved
for   marketing   by  the  FDA.  In   addition,   Avonex,   a  similar  form  of
beta-interferon,  and  Copaxone,  a random  peptide  polymer,  have received FDA
approval for relapsing  remitting MS. In clinical trial with the beta-interferon
products, these therapies slowed progression of disease in MS patients, yet lead
to a variety of side effects including "flu-like" symptoms.

     Neurocrine's  cofounder,  Dr.  Lawrence  Steinman,  identified the dominant
invading  T cell in the  brains of  patients  who had died of MS.  Dr.  Steinman
further  identified the dominant target or recognition site on the myelin sheath
to which  invading  T cells  bind.  Neurocrine  has  exclusively  licensed  this
technology and has designed  altered  peptide  ligands,  which  resemble  native
disease-causing  molecules  of the  myelin  sheath.  These  molecules  have been
altered  to  attract  and bind to  disease-causing  T cells  and  inhibit  their
destructive capabilities.  Neurocrine's altered peptide ligand for the treatment
of MS has been shown to reverse  disease in animal models of MS and decrease the
production of cytokines such as gamma interferon and tumor necrosis factor-alpha
which contribute to the disease. These same molecules demonstrate the ability to
silence  pathogenic T cells from MS patients in vitro.  Together with  Novartis,
the Company's  collaborative  partner for this program,  Neurocrine filed an IND
and  received  approval in 1996 to  commence  clinical  trials.  The Company and
Novartis  subsequently  completed  Phase I  clinical  trials,  and two  Phase II
clinical trials currently underway in North America and Europe and are scheduled
to complete by the fourth  quarter of 1999 or the first  quarter  2000.  Results
obtained  in  animal  models of MS are not  necessarily  predictive  of  results
obtained in man,  and Phase I trials are not  designed to predict  efficacy.  No
assurance,  therefore, can be given that Novartis will successfully complete the
current Phase II clinical  studies or that results of these studies will warrant
additional clinical development of potential product.

Type I Diabetes

     Utilizing its experience in the development of APL for Multiple  Sclerosis,
Neurocrine has extended this approach to Type I or juvenile-onset diabetes. Like
MS, in Type I  diabetes  the  immune  system has  erroneously  targeted  healthy
tissue,  in this case the  pancreatic  cells  responsible  for the production of
insulin.  Type I diabetes is one of the most prevalent chronic conditions in the
North America,  afflicting  approximately  890,000  patients in 1997.  Diabetics
suffer from a number of  complications  of the disease  including heart disease,
circulatory  problems,  kidney  failure,  neurologic  disorders  and  blindness.
Current  therapy for Type I diabetes  consists of daily  insulin  injections  to
regulate blood glucose levels.

     The Company believes that an altered peptide ligand specific for autoimmune
T cells involved in diabetes may stop the  destruction of the insulin  secreting
cells in  pre-diabetic  patients,  thus  allowing them to delay or avoid chronic
insulin  therapy.  Working  with a leading  Diabetologist  at the Barbara  Davis
Center  for  Childhood  Diabetes  at  the  University  of  Colorado,  Neurocrine
scientists have engineered one of the dominant  pancreatic  antigens which is no
longer recognized by the pathogenic immune cell. In preclinical  models this APL
was capable of eliciting a protective  immune response by generating  cells that
secrete  factors  capable of  regulating  the  destructive  cells  reducing  the
incidence of diabetes. In addition,  experiments using immune cells derived from
the blood of Type 1 diabetes patients indicate that APL are recognized by immune
cells  response to insulin,  suggesting  that the APL may have the  potential to
intervene in the disease process in humans. Neurocrine is currently conducting a
Phase I safety and dose  escalating  clinical  program in  diabetic  patients in
Europe.  The results of the Company's  preclinical  studies in animals and cells
derived from Type I diabetes  patients  are not  necessarily  predictive  of the
results the Company will see treating Type I diabetes patients.  There can be no
assurance  that the APL will prove  safe in Phase I studies or that the  Company
will conduct additional clinical trials.

IL-4 Fusion Toxin

     IL-4 receptors are highly expressed in malignant brain tumors as well as in
cancers of the breast,  kidney, lung, colon, stomach,  ovary,  prostate,  and in
melanoma and mesothelioma.  Immunotoxins are a novel form of anticancer  therapy
under  investigation  in a variety of clinical  situations.  The  immunotoxin is
designed to carry a cellular toxin,  such as Pseudomonas  exotoxin,  to a target
antigen,  expressed on cancer cells.  Targeted  toxins have several  theoretical
advantages over  conventional  chemotherapy in that they may be extremely potent
and effective in chemotherapy-resistant T cells.

     Malignant brain tumors,  both primary and metastatic,  are a major cause of
cancer death.  Despite current therapeutic  options such as surgery,  radiation,
and chemotherapy, the median survival rate for malignant brain cancer is only in
the range of 9-12 months. Approximately 17,400 new cases of primary brain cancer
and 75,000 cases of  metastatic  brain tumor are  diagnosed in the United States
each  year,  with  comparable  incidence  numbers in  Europe.  According  to the
American  Cancer  Society,  the  incidence of malignant  brain tumors is rising.
Glioblastoma  (grade 4 astrocytoma)  is the most common primary  malignant brain
tumor.  These tumors arise within the brain and generally remain confined to the
brain.  The clinical course of glioblastoma is  characterized by relentless loss
of vital neurological functions and death within approximately twelve months.

     In 1998, the Company  exclusively  licensed from the National Institutes of
Health an anti-cancer compound,  referred to as IL-4 Fusion Toxin.  NBI-3001, or
IL-4 Fusion  Toxin is an  immunotoxin  which  fuses  interleukin-4  ("IL-4"),  a
cytokine, to Pseudomonas  exotoxin.  This molecule was designed as a result of a
collaboration between the FDA and the National Cancer Institute.  IL-4 receptors
Fusion  Toxin is a  chimeric  protein  in which a cytokine  (blood  cell  growth
factor)  known as  interleukin  4 (IL-4) has been joined  together  with another
molecule,  an exotoxin that can destroy  cancer  cells.  The IL-4 portion of the
Fusion Toxin  preferentially binds to human cancer cells, which express elevated
levels of high affinity  receptors for IL-4 on their  surface.  The advantage of
targeting  the IL-4  receptor is that  expression  of the  receptor is absent or
undetectable in normal brain tissue.

     In the preclinical setting,  NBI-3001 has been found to be highly cytotoxic
to brain tumor cell lines in vitro, and exhibits  anti-tumor activity in in vivo
models of brain tumor.  NBI-3001  has  completed a Phase I safety trial under an
Investigator  sponsored  IND in which  (9)  patients  with  recurrent  malignant
glioblastoma   were  treated.   Results  were   presented  at  The  Society  for
Neuro-Oncology   Meeting  in  an  abstract   entitled  "A  Circularly   Permuted
Interleukin-4  Pseudomonas Exotoxin for Treatment of Malignant Gliomas." In this
study,  NBI-3001  produced no evident  systemic or  neurological  toxicities  as
documented by serum  chemistry,  hematology  screen  including  liver panels and
neurological  examinations.  A physician-IND clinical trial does not replace the
need for  Company-sponsored  clinical  trials,  but can  provide  a  preliminary
indication as to whether further clinical trials are warranted. However, results
from the Physician IND sponsored  clinical study may not be repeated in a larger
study.  NBI-3001 is currently undergoing a Phase I/II trial targeting enrollment
of thirty  (30)  subjects  with  recurrent  glioblastoma  in which  the  primary
endpoints are safety,  tumor  regression,  and  progression  free survival.  The
Company  intends to complete  enrollment  of this trial in 1999,  and if results
warrant, commence an efficacy trial for NBI-3001 in early 2000. No assurance can
be given  that the  Company  will  successfully  complete  clinical  testing  or
progress to later clinical trials in a timely manner, or at all.

GABA Subtype Receptor Agonists

Insomnia

     The term  "insomnia"  is used to  describe  all  conditions  related to the
perception  of inadequate or  non-restful  sleep by the patient.  According to a
Gallup Survey conducted on behalf of the National Sleep  Foundation,  49% of all
Americans say that they have trouble  sleeping.  Often undiagnosed or dismissed,
insomniacs  have trouble  falling  asleep,  remaining  asleep or staying  awake.
Insomnia was also shown to be related to the age and sex of the individuals, the
prevalence of which is higher in older  individuals and females.  While insomnia
is  reported  to be a major  problem  in the adult  population  worldwide,  only
approximately  10% of such patients seek prescription  sleeping  medications for
their condition.  This fact may result from the perceived side effect profile of
currently marketed sedative-hypnotics.

     In the recent  past,  the majority of patients  treated for  insomnia  have
utilized  non-benzodiazepine  compounds,  which  show an  improved  side  effect
profile over the benzodiazepine class of sedative-hypnotics  utilized during the
1980's.  However,  currently  marketed  products  continue  to  exhibit  certain
unfavorable  side  effects,   including   synergy  with  other  CNS  depressants
(especially alcohol),  the development of tolerance upon repeat dosing,  rebound
insomnia following discontinuation of dosing, hangover effects the next day, and
impairment of psychomotor  performance and memory. Memory impairment,  which can
include amnesia for events occurring prior to and after drug administration,  is
of  particular  concern in the elderly whose  cognitive  function may already be
impaired by the aging process.  The elderly population,  which represent a large
portion  of  the  insomnia  market,   would  especially  benefit  from  a  novel
therapeutic with an improved safety profile,  rapidity of onset, and decrease in
memory impairment.

     In 1998 the Company signed an exclusive  worldwide licensing agreement with
DOV  Pharmaceuticals,  Inc.  for a  compound  in  clinical  development  for the
treatment of insomnia. The compound,  NBI-34060, works through the activation of
the benzodiazepine site on a GABA receptor subtype. It is through this mechanism
that the currently marketed therapeutics produces their sleep-promoting effects.
However,  NBI-34060, a next generation compound, is chemically distinct from the
benzodiazepines with a potentially improved pharmacokinetic profile and receptor
subtype  selectivity,  which may reduce the side effects  characteristic  of the
currently marketed products.

     Receptor  binding  studies  and  preclinical  animal  studies on  NBI-34060
indicate that it is a highly potent GABAA receptor agonist specific for the Type
1 site.  In animal  studies,  NBI-34060  shows a reduced  tolerance to sedation,
suggesting a lower potential for abuse, and a reduced tendency to potentiate the
deleterious effects of alcohol. In addition,  in animal models NBI-34060 appears
to be devoid of next day hangover effects and is expected to have a considerably
reduced amnestic potential.

     Prior to licensure by the Company,  a Phase I clinical  trial was conducted
in forty-two (42)  subjects.  The study was designed to determine the safety and
tolerance  of   NBI-34060,   and  provide  a   preliminary   evaluation  of  the
sedative-hypnotic potential in normal volunteers as reflected in self-ratings of
drowsiness,  disruption of memory,  and impairment of  psychomotor  performance.
NBI-34060  was well  tolerated,  with no serious or  unexpected  adverse  events
("AEs")  reported.  The only  consistently  reported side effect was drowsiness,
indicating  strong  potential  for  the  sedative-hypnotic   properties  of  the
compound.

     Based on  results  from this Phase I study,  in the first  quarter of 1999,
Neurocrine completed a Phase Ib clinical trial in thirty (30) healthy volunteers
to further explore the safety and kinetic profile of NBI-34060.  As demonstrated
in the first Phase I trail,  NBI-34060  demonstrated an adequate safety profile.
The Company  currently intends to conduct a Phase II clinical program in 1999 to
evaluate the efficacy of NBI-34060  in subjects  with chronic  insomnia,  and if
results  warrant,  initiate a pivotal  Phase III trial in 2000.  There can be no
assurance  that the side effects and efficacy  profile of NBI-34060  seen in the
Company's  animal  models and Phase I trials will be  confirmed  in the Phase II
trial or that the results of the Phase II trial will warrant further study.

CRF / Urocortin Agonist

     The body has several mechanisms to regulate the effects of CRF. CRF-binding
protein  ("CRF-BP")  binds to CRF and  holds it in an  inactive  state,  tightly
regulating  levels of CRF in certain brain  regions.  CRF-BP may provide a novel
target to  selectively  increase  levels of CRF in diseases that are  associated
with  decreased  levels of CRF,  such as  Alzheimer's  disease and  obesity.  In
addition, agonists of the CRF-2 receptor may represent a therapeutic strategy to
elevate CRF and a related  neuropeptide  urocortin  for the  treatment  of these
disorders.

Alzheimer's Disease

     Alzheimer's  disease is a  neurodegenerative  brain  disorder that leads to
progressive  memory loss and dementia.  Alzheimer's  disease generally follows a
predictable  course of deterioration over eight years or more, with the earliest
symptom being impairment of short-term memory. Gradually, memory loss increases,
reasoning  abilities  deteriorate,  and individuals become depressed,  agitated,
irritable  and  restless.  In the final stages of the disease,  patients  become
unable  to  care  for   themselves.   According  to  the  National   Alzheimer's
Association, in 1994 over four million individuals in the United States suffered
from  Alzheimer's  disease.  Alzheimer's  disease is the fourth leading cause of
death  for  adults,  responsible  for over  100,000  deaths  in  1994.  Marketed
therapies  currently  available  for the  treatment of  Alzheimer's  disease are
severely  limited.  Tacrine and Aricept  have been  recently  approved  for this
indication,  but,  show limited  memory  improvement  in  Alzheimer's  patients;
concerns  regarding  drug-induced  elevations  in liver  enzymes  and other side
effects have limited the widespread use of these products.

     Neurocrine  scientists have found that there are  significant  decreases in
CRF levels in the brain areas that are affected in Alzheimer's disease. In spite
of reduced CRF  concentrations,  CRF-BP levels are not decreased in areas of the
brain  affected by  Alzheimer's  disease,  thereby  providing the Company with a
novel  target for drug  intervention.  Consequently,  Neurocrine  is  developing
CRF-BP  antagonists  to displace  CRF from the binding  protein and  effectively
increase the amount of "free CRF"  available to interact with the CRF receptors.
This strategy is expected to selectively raise the concentration of CRF in brain
areas  involved in learning and memory  processes.  Because the  therapeutic  is
designed  to  restore  normal  levels of CRF only in these  areas,  the  Company
believes  that the drug  will  not  induce  the  side  effects  associated  with
administering  CRF directly,  such as anxiety.  Current  efforts are underway to
identify  and  optimize  molecules  through  high-throughput  screening of small
molecule libraries.  However, no assurance can be given that the Company and its
corporate  partner,  Eli Lilly,  will successfully  identify suitable  candidate
compounds for development in a timely manner, or at all.

Obesity

     Obesity is the most common nutritional  disorder in Western  societies.  As
many as three in ten adult Americans weigh at least 20% in excess of their ideal
body weight,  and 35 million  people in the United States are  characterized  as
clinically obese.  Increased body weight is a significant  public health problem
because it is associated  with a number of serious  diseases,  including Type II
diabetes, hypertension, hyperlipidemia and several cancers. Although obesity has
been commonly considered to be a behavioral problem,  there is now evidence that
body  weight is  physiologically  regulated.  The  regulation  of body weight is
complex  and  appears to  consist  of both  centrally  and  peripherally  acting
mechanisms.

     Preliminary data indicates that CRF and a related neuropeptide,  urocortin,
may act as central  regulators of both appetite and  metabolism.  Neurocrine has
evaluated CRF-BP  antagonists and CRF receptor agonists in various animal models
of obesity  and have  shown  effects of  reduced  food  intake and weight  loss.
Neurocrine  and its corporate  partner Eli Lilly are  screening  and  optimizing
small molecule  compounds for evaluation in  confirmatory  preclinical  studies.
However,  no assurance can be given that the Company and its  corporate  partner
will successfully  identify CRF and urocortin  agonists suitable as anti-obesity
therapeutics  in a timely manner,  or at all.  Further,  even if the Company and
Lilly are successful in identifying  drug  candidates,  the results  obtained in
animals are not  necessarily  predictive of results  obtained in humans,  and no
assurance  can be given that the Company  will  progress  to clinical  trials or
successfully complete clinical trials in a timely manner, if at all.

Excitatory Amino Acid Transporters ("EAATs")

     EAATs serve as novel targets for the  development of drugs,  which modulate
toxic levels of glutamate in the brain.  Neurotransmitter  transporters  play an
important  role in regulating the levels of  neurotransmitters,  and some of the
most successful CNS drugs are ones that selectively  target these  transporters.
For example,  the Selective  Serotonin  Reuptake  Inhibitors  ("SSRIs")  such as
Prozac selectively  inhibit the serotonin  transporter  modulating the serotonin
levels for therapeutic benefit. Similarly,  Neurocrine is targeting the EAATs to
selectively modulate the levels of the excitatory  neurotransmitter glutamate to
produce a therapeutic  benefit in disorders where glutamate  levels are abnormal
such as in  stroke,  head  trauma,  retinal  ischemia,  schizophrenia  and other
neurodegenerative  and  psychiatric  disorders.   Neurocrine  has  entered  into
collaboration  with Wyeth-Ayerst  focusing on modulating  glutamate  transporter
function as a novel strategy for the treatment of  neurodegenerative  disorders.
Neurocrine and  Wyeth-Ayerst  will target the EAATs to selectively  modulate the
levels of the  excitatory  neurotransmitter  glutamate to produce a  therapeutic
benefit in disorders where glutamate levels are abnormal.  These activities will
include  basic  research  to  understand  the  function  and  regulation  of the
transporters,  the  identification  of suitable  chemical  hits,  along with the
identification and  characterization of chemical and biological leads. There can
be no  assurance  that  the  Company  and  Wyeth-Ayerst  will be  successful  in
demonstrating  EAATs as  therapeutic  targets  or that  they will  identify  any
product candidates for pre-clinical or subsequent clinical development.






Melanocortin Receptor Antagonists

     Melanocortin receptors are involved in the control of endocrine,  autonomic
and central  nervous  system  function.  To date, a family of five  melanocortin
receptor subtypes has been identified;  several of which have been cloned by the
Company's consultants and scientists. One of the melanocortin receptor subtypes,
MC4, has recently  been  identified  as an important  regulating  mechanism  for
appetite,  body weight and insulin secretion which represents a novel target for
the  treatment  of  obesity  and  diabetes.   This   technology   combined  with
Neurocrine's  expertise  in  obesity,  anorexia  nervosa and  diabetes  provides
additional avenues for the discovery of effective therapies for the treatment of
other endocrine functions and brain disorders.

Chemokines

     Chemokines are immune / inflammatory  mediators  considered  central to the
trafficking of leukocytes.  Restricted and sub-type specific expression of their
receptors in different pathologies and on T lymphocytes, dendritic cells and CNS
tissue,  suggests a role for these  mediators in diseases  characterized  by CNS
inflammation and leukocyte invasion.  All  ligand-receptor  interactions lead to
migration of the cell types  expressing the receptor,  hinting at a central role
for these  molecules in the  recruitment  / invasion of the  diseased  tissue by
these cells and their potential role in the ensuing  destruction.  Antagonism of
this effect may, therefore, be of benefit. In addition to an in-depth program of
discovery research,  the Company has decided to screen our library against these
receptor  systems  in  order  to  identify  small  molecule  antagonists.  Since
chemokines  are large  proteins and have multiple  interaction  sites with their
receptors, the design of specific, high-affinity competitive antagonists will be
required.  Antagonists are being tested in inflammatory  animal models including
experimental  autoimmune   encephalomyelitis  (EAE,  for  MS),  arthritis,   and
diabetes.

     Given the complexity of the chemokine  area,  Neurocrine has focused on the
more  recently  discovered  receptors in an attempt to generate  small  molecule
antagonists.  To that end,  numerous  chemokine  receptors have been  expressed,
screened  against our small molecule  library,  and structure  activity  studies
undertaken.  There can be no assurance that the Company's  research in this area
will lead to product candidates.

Gonadotrophin-Releasing Hormone (GnRH) Receptor

     Gonadotrophin-releasing   hormone  is  a  hypothalamic   decapeptide   that
stimulates  the secretion of the pituitary  gonadotropins,  luteinizing  hormone
(LH) and  follicle-stimulating  hormone (FSH). The  gonadotropins,  in turn, are
necessary  for gonadal  steroid  production  and normal  reproductive  function.
Chronic  administration  of GnRH  superagonist  peptides has been found to cause
down  regulation  of the GnRH receptor  resulting in a paradoxical  reduction in
circulating   levels  of  testosterone  or  estrogen,   equivalent  to  surgical
castration  or  oophorectomy,  respectively.  This  reversible  shutdown  of the
reproductive  endocrine axis has proven  clinically  useful in treating  hormone
dependent proliferative diseases such as endometriosis,  prostate carcinoma, and
breast cancer, and resulted in several peptide drugs such as Lupron and Zoladex,
with an  estimated  market in excess of $1  billion.  However,  current  peptide
agonist  based drugs have several  drawbacks.  They require 3-4 weeks before the
regulatory  activities  are observed,  and during this period their  stimulatory
effects can result in a  worsening  of the  disease.  Being  peptides  they also
require  subcutaneous  injection or nasal  administration  and are  expensive to
manufacture.

     The Company  has  screened  its small  molecule  library and has  conducted
structure  activity studies aimed at producing a small molecule GnRH antagonist.
Several  series of small molecule  compounds have been  identified and are being
evaluated as candidates for further development.

Neurogenomics

     The brain and  spinal  cord are  comprised  of two major cell types - glial
cells and neurons.  Glial cells are the most prevalent cell types in the central
nervous system,  comprising over 75% of all brain cells.  The gene products from
these cells are crucial for the survival and development of neurons. Neurons are
CNS cells that transmit and receive  complex  electrical  and chemical  messages
from other neurons to control all cognitive  processes.  In certain pathological
states,  excessive  glial  activity  results in the  activation  of cytosine and
related  genes.  The proteins  encoded by these genes may be  implicated  in the
degenerative  cascade  leading to  neurological  disorders  such as  Alzheimer's
disease,  stroke,  multiple sclerosis,  Parkinson's  disease,  epilepsy and AIDS
dementia.  For example,  in AIDS, the HIV virus does not attack neurons but does
infect  glial  cells  which in turn  release  inflammatory  cytokines  and other
factors  which  are  toxic  to  neurons.   Similarly,  in  Alzheimer's  disease,
accumulating  evidence suggests complex interactions between neurons, glia and a
protein  fragment  known as beta amyloid  leading to formation of senile plaques
and neurodegeneration.  Currently, it is estimated that only a small fraction of
genes involved in  neurodegeneration  or regeneration has been  identified.  The
identification of novel CNS genes involved in the neurodegenerative  process may
yield new therapeutic opportunities.

Neurodegenerative Diseases and Disorders

     Neurodegenerative  diseases and  disorders  involve  damage to the cellular
structure of the brain either acutely,  as in stroke or trauma,  or chronically,
as in  epilepsy  and  Alzheimer's  disease.  To date,  only a limited  number of
effective  therapeutics  exists to treat  neurological  disorders,  resulting in
significant  economic  and social  costs.  In 1998,  over 26 million  people are
estimated in the United States to be affected by neurological disorders.

     Activation  of glial  cells is a common  feature of many  neurodegenerative
diseases. The primary goal of Neurocrine's  Neurogenomics program is to identify
and  characterize  novel genes that are induced in glial cells under  conditions
that lead to  neurodegeneration  or  regeneration.  The  Company is  focusing on
stroke,  multiple sclerosis,  AIDS dementia,  epilepsy,  Parkinson's disease and
Alzheimer's  disease. The unique conditions leading to neurodegeneration in each
of the disorders have been established in both animal and cellular models of the
disease.  Neurocrine is actively  isolating and analyzing genes  associated with
neuronal  cell  death  utilizing  state  of  the  art  molecular  biology,  gene
sequencing  and   bioinformatics.   In  addition,   activated   genes  that  are
neuroprotective or allow for the regeneration of neurons may also be identified.

     Novel  neurodegenerative  genes that are discovered  may include  proteins,
enzymes or receptors.  Protein  signaling  molecules or the genes  encoding such
molecules may be utilized as therapeutics, while enzymes and receptors may serve
as new targets for drug  discovery.  Neurocrine  currently  intends to place the
receptors and enzymes  encoded by these genes in  high-throughput  screens in an
attempt to  discover  small  molecule  therapeutics  to treat  neurodegenerative
disorders. To date, the Company has identified novel genes of which a number are
undergoing  biological  evaluation  in in vitro and animal  models.  The Company
currently  intends to identify  candidate genes as drugs or drug targets for one
or more  neurological  diseases.  However,  there can be no  assurance  that the
Company will successfully identify suitable gene candidates for development in a
timely manner, or at all.



BUSINESS STRATEGY

     The Company's  strategy is to utilize its  understanding  of the biology of
the central nervous,  immune and endocrine systems to identify and develop novel
therapeutics. There are five key elements to the Company's business strategy:

     Target Multiple  Product  Platforms.  The Company  believes certain central
nervous system drug targets,  such as CRF,  EAATs and MCH represent  significant
market  opportunities  in  psychiatric,   neurologic  and  metabolic  disorders.
Immunological  targets,  such as  altered  peptide  ligands,  offer  therapeutic
strategies  related to autoimmune  diseases.  Neurogenomics and chemokines allow
the Company to combine its neuroscience  and immunology  expertise with new drug
discovery  technologies to identify novel  gene-related  product or gene therapy
opportunities.

     Identify Novel Neuroscience and Immunology Drug Targets for the Development
of  Therapeutics  Which  Address  Large Unmet Market  Opportunities.  Neurocrine
employs  molecular  biology as an enabling  discipline  to  identify  novel drug
targets such as receptors,  genes and  gene-related  products.  The Company uses
advanced  technologies,   including  combinatorial  chemistry,   high-throughput
screening,  gene  sequencing and  bioinformatics,  to discover and develop novel
small molecule  therapeutics  for diseases and disorders of the central  nervous
and immune systems including anxiety, depression,  Alzheimer's disease, multiple
sclerosis, neurodegeneration, diabetes, obesity and insomnia.

     Leverage Strategic Alliances to Enhance  Development and  Commercialization
Capabilities.  Neurocrine  intends to leverage the  development,  regulatory and
commercialization   expertise  of  its  corporate  partners  to  accelerate  the
development  of  its  potential   products,   while   retaining   commercial  or
co-promotion  rights in North America.  The Company intends to further  leverage
its  resources  by  continuing  to enter  into  strategic  alliances  and  novel
financing mechanisms to enhance its internal  development and  commercialization
capabilities.

     To date,  Neurocrine  has entered  into  strategic  alliances  with Janssen
focusing on CRF receptor antagonists to treat anxiety, depression, and substance
abuse; with Novartis to develop altered peptide ligands for the treatment of MS;
and   with   Lilly   to   collaborate   in  the   discovery,   development   and
commercialization  of CRF-BP  antagonists  and CRF agonists for the treatment of
central  nervous  system  disorders  including  obesity  and  dementias  such as
Alzheimer's  disease.  More recently,  the Company  entered into a collaboration
with   Wyeth-Ayerst    Laboratories   for   the   research;    development   and
commercialization of compounds with modulate excitatory amino acid transporters.
The  Company  has also formed NPI, a research  and  development  subsidiary,  to
finance  its  Neurosteroid   clinical  development   program,   which  has  been
discontinued and its Neurogenomics  programs. In 1999 the Company entered into a
collaboration agreement with Wyeth-Ayerst to research, develop and commercialize
compounds which modulate  excitatory amino acid  transporters  ("EAATs") for the
treatment of neurodegenerative and psychiatric diseases.

     In  addition,  in 1998  Neurocrine  entered into two  alliances  with other
companies to enhance its drug discovery and development capabilities.  The first
alliance is with Medtronic Inc. to study the stability and compatibility of IL-4
Fusion  Toxin in  Medtronic's  implantable  drug pump and catheter  system.  The
second  alliance  is with  Caliper  Technologies.  Neurocrine  and  Caliper  are
collaborating  to apply  Caliper's  microfluidics  technology to the  ultra-high
throughput screening of Neurocrine's proprietary targets.

     Outsource  Capital  Intensive  and  Non-Strategic  Activities.   Neurocrine
intends  to focus its  resources  on  research  and  development  activities  by
outsourcing its requirements for manufacturing, preclinical testing and clinical
monitoring activities.  The Company utilizes contract current Good Manufacturing
Processes ("cGMP") manufacturing for clinical programs including the IL-4 Fusion
Toxin program,  insomnia and diabetes.  Neurocrine believes that availability of
skilled contract  manufacturers  and contractors will allow the Company to focus
on its core discovery and development  programs to generate  additional  product
opportunities.

     Acquire Complementary Research and Development Drug Candidates.  Neurocrine
plans to continue to selectively acquire rights to products in various stages of
research and clinical  development  in the fields of neurology and immunology to
take advantage of the development and future  commercialization  capabilities it
is developing in cooperation  with its strategic  partners.  In 1998 the Company
licensed  from the National  Institutes  of Health an IL-4 Fusion Toxin which is
currently in Phase I/II clinical trials for recurrent glioblastoma.  In May 1998
the Company  completed the  acquisition  of Northwest  NeuroLogic,  Inc.  (NNL),
acquiring  the  intellectual  property  surrounding  the  Excitatory  Amino Acid
Transporters (EAATs) 1 through 5 and Melanocortin  receptors.  In addition,  the
scientific  founders  of NNL,  Drs.  Roger Cone and Susan  Amara,  of the Vollum
Institute  became exclusive  consultants to the Company.  Also in June 1998, the
Company   exclusively    licensed   worldwide   commercial   rights   from   DOV
Pharmaceuticals,  Inc.  for a  compound  which has  completed  Phase I  clinical
development for the treatment of insomnia.



TECHNOLOGY

     Neurocrine  utilizes  advanced  technologies  to enhance its drug discovery
capabilities and to accelerate the drug development process.  These technologies
include:

     High-Throughput  Screening  ("HTS").  Neurocrine  has  assembled a chemical
library of diverse,  low molecular  weight  organic  molecules for lead compound
identification.  The Company has  implemented  robotics  screening  capabilities
linked to its library of compounds that facilitate the rapid  identification  of
new drug  candidates  for multiple drug targets.  The Company  believes that the
utilization  of  high-throughput  screening and medicinal and peptide  chemistry
will enable the rapid identification and optimization of lead molecules.

     Combinatorial  Chemistry.  Recent  developments in both  computational  and
combinatorial  chemistry  have shown  that it is now  possible  to design  small
libraries  focused  around hits emerging  from HTS both to evaluate  rapidly the
quality  of such hits and also  subsequently  optimize  the  selected  hits into
advanced lead candidates. The approach involves learning from the set of hits as
a whole and using this  information to design libraries of compounds that may be
structurally  independent  of the original  hits.  Neurocrine  is acquiring  the
necessary  technologies  to facilitate the process of library  design,  parallel
synthesis and rapid purification and  characterization of compounds.  Neurocrine
will use the same process to  supplement  the  corporate  compound  library with
structures  relevant for internal projects and hence improve the likelihood that
HTS will discover a meaningful array of useful hits.

     Molecular Biology. Neurocrine scientists have utilized novel techniques for
examination of gene expression in a variety of cellular systems. The company has
developed a  sophisticated  technique to evaluate the type and quantity of genes
in various cellular systems prior to the isolation of genes. Neurocrine has also
developed  unique  expression  vectors  and cell lines that allow for the highly
efficient protein expression of specific genes.

     Gene Sequencing. Neurocrine applies integrated automated DNA sequencing and
gene  identification  technology  in  its  Neurogenomics  program.  The  systems
utilized  by   Neurocrine   allow  for  extended   gene  analysis  in  a  rapid,
high-throughput  format with independent linkage into a sequence  identification
database.   Neurocrine  has  optimized  gene  sequencing   instrumentation   for
"differential display," a technique that may facilitate the rapid identification
of novel genes.

     Bioinformatics.  Neurocrine's  Neurogenomics  program creates a significant
amount of genetic sequence  information.  Applied genomics relies on information
management  systems to collect,  store and  rapidly  analyze  thousands  of gene
sequences.  Neurocrine has developed a bioinformatics  system, which the Company
believes  will  allow  it  to  identify  novel  genes,  which  are  involved  in
neurodegeneration.  Data are collected by automated  instruments  and stored and
analyzed  by  Neurocrine   using  customized   computational   tools.  To  date,
Neurocrine's molecular biologists have identified over 4,500 novel genes.



STRATEGIC ALLIANCES

     The Company's business strategy is to utilize strategic alliances and novel
financing   mechanisms  to  enhance  its   development   and   commercialization
capabilities. To date, Neurocrine has completed the following alliances:

JANSSEN PHARMACEUTICA, N.V.

     On January 1, 1995,  Neurocrine  entered  into a research  and  development
agreement  with  Janssen  to  collaborate  in  the  discovery,  development  and
commercialization  of CRF  receptor  antagonists  focusing on the  treatment  of
anxiety,   depression  and  substance  abuse  (the  "Janssen  Agreement").   The
collaboration  utilizes Neurocrine's expertise in cloning and characterizing CRF
receptor  subtypes,  CRF pharmacology and medicinal  chemistry.  Pursuant to the
Janssen Agreement, the Company has received $2.0 million in license payments. In
connection with the Janssen Agreement, Johnson & Johnson Development Corporation
("JJDC")  purchased $5 million of the Company's Common Stock. The  collaborative
research portion of the Janssen Agreement was completed as scheduled in 1997.

     In 1996 Janssen selected a clinical candidate and commenced clinical trials
in Europe. Under the Janssen Agreement,  Neurocrine is entitled to receive up to
$10.0 million in milestone payments for the indications of anxiety,  depression,
and  substance  abuse,  and up to $9.0 million in  milestone  payments for other
indications, in each case upon achievement of certain development and regulatory
goals.  As of  December  31,  1998 the  Company  has  received  $3.5  million in
milestone payments from Janssen. Janssen is responsible for funding all clinical
development and marketing activities,  including reimbursement to Neurocrine for
its  promotional  efforts,  if any. The Company has granted Janssen an exclusive
worldwide license to manufacture and market products developed under the Janssen
Agreement. The Company is entitled to receive royalties on Janssen product sales
throughout the world. The Company has certain rights to co-promote such products
in North  America.  There can be no assurance that the Company and its corporate
partner will be  successful in  developing,  receiving  regulatory  approvals or
commercializing  any potential products  discovered under the Janssen Agreement.
As a result, there can be no assurance that any product development milestone or
royalty payments will be made.
NOVARTIS

     In January 1996, the Company  entered into a binding letter  agreement with
Ciba-Geigy  (which  subsequently  became  Novartis) to develop  altered  peptide
ligand  therapeutics  for the  treatment  of MS based  upon the  Company's  drug
development  candidates  and expertise in immunology and protein  chemistry.  In
December 1996, the Company and Novartis entered into a definitive agreement (the
"Novartis  Agreement")  incorporating  the terms and conditions set forth in the
letter agreement and certain other terms and conditions agreed to by the Company
and Novartis.  Novartis paid the Company a $5.0 million non-refundable fee prior
to executing the Novartis Agreement.  In connection with the Novartis Agreement,
Novartis purchased $10.0 million of the Company's Common Stock.  Pursuant to the
Novartis  Agreement,  Novartis is  obligated  to provide  the Company  with $3.5
million  in  research  and  development  funding,  plus  certain  other  program
expenses, each year for five years ending on December 31, 2000. In event that no
biological  license  application  ("BLA")  has been  filed  as a  result  of the
collaboration  by December 31, 2000,  then  Novartis may be obligated to provide
the Company with an additional $2.5 million per year thereafter  until a Product
License  Application is filed, except in certain  circumstances.  As of December
31, 1998 the Company has  received a total of $20.2  million in license fees and
research  funding  under the  Novartis  Agreement  (including  the $5.0  million
non-refundable  fee).  Neurocrine is also entitled to receive milestone payments
if  certain  research,  development  and  regulatory  milestones  are  achieved.
Milestone  payments  were  $3.8  million  and $2.3  million  in 1997  and  1998,
respectively.  Novartis has the right to terminate the Novartis Agreement on six
months' notice, which may be given at any time after December 30, 1997.

     The Company has granted Novartis an exclusive license outside of the United
States and Canada to market altered peptide ligand products  developed under the
Novartis  Agreement  for multiple  sclerosis.  Neurocrine is entitled to receive
royalties on product sales in these territories. The Novartis Agreement provides
that the Company and  Novartis  will  collaborate  in the  marketing of products
developed  under  the  Novartis  Agreement  in the  United  States  and  Canada.
Neurocrine is entitled to receive a share of the profits resulting from sales of
altered  peptide ligand  products in the United States and Canada subject to the
recoupment of a portion of Novartis's development costs.  Neurocrine retains the
right to convert its profit  share to the right to receive  royalty  payments at
its sole  discretion in which case no repayment of development  costs are due to
Novartis  and Novartis  will have  exclusive  marketing  rights.  Neurocrine  is
obligated to repay a portion of the development  costs of any potential  product
developed pursuant to the collaboration  unless the Company elects to convert to
the  right to  receive  royalty  payments.  There can be no  assurance  that the
Company and Novartis will be successful  in  developing or  commercializing  any
potential  products.  As a result,  there can be no  assurance  that any product
development milestone, royalty, or profit sharing payments will be made.

ELI LILLY AND CO.

     On  October  15,  1996,  Neurocrine  entered  into a research  and  license
agreement  (the "Lilly  Agreement")  with Lilly to collaborate in the discovery,
development and  commercialization  of CRF binding protein ligand inhibitors for
the  treatment  of  central  nervous  system  disorders  including  obesity  and
dementias  such as  Alzheimer's  disease  and CRF-2  agonists  for CNS  mediated
diseases  and  disorders.  Neurocrine  has  received  $14.5  million in research
payments under the Lilly Agreement,  of which $4.0 million was received in 1998.
Neurocrine  expects to receive an additional  $3.0 million in research  payments
through October 31, 1999, as well as additional sponsored research payments over
the  subsequent  two-year  period if certain  milestones  are met,  and up to an
additional  $49.0  million in milestone  payments for the first two products for
dementia  or  obesity if  certain  development  and  regulatory  milestones  are
achieved.  The Company  has  granted  Lilly an  exclusive  worldwide  license to
manufacture and market CRF binding protein ligand  antagonists and CRF-2 agonist
products. Lilly is obligated to fund clinical development and marketing expenses
(except  as set  forth  below)  and is  responsible  for  clinical  development,
regulatory compliance, and manufacturing of products.  Neurocrine is entitled to
royalties on product sales.  At its option,  Neurocrine is entitled to receive a
portion of the profits  resulting  from sales of products  for the  treatment of
dementia in the United  States  (subject to the  Company's  obligation  to pay a
portion of the development costs for such product).  Lilly has agreed to provide
the  Company  with  access to a portion of its  chemical  compound  library  for
screening  against targets outside of the field of the Lilly Agreement and other
Lilly program areas,  subject to the Company's obligation to pay Lilly royalties
on sales of products  developed based on compounds in such library and milestone
payments  based upon certain  development  and  regulatory  milestones  for such
products.  There can be no assurance that the Company's research under the Lilly
Agreement will be successful in discovering any potential products or that Lilly
will  be  successful  in  developing,   receiving   regulatory   approvals,   or
commercializing any potential products that may be discovered. As a result there
can be no assurance that any product development  milestone,  royalty, or profit
sharing payments will be made.

WYETH-AYERST

     Effective  January 1, 1999, the Company  entered into a  Collaboration  and
License Agreement relating to the research, development and commercialization of
compounds which modulate  excitatory amino acid  transporters  ("EAATs") for the
treatment  of  neurodegenerative  and  psychiatric  diseases.  Pursuant  to  the
agreement,  Wyeth-Ayerst  will  provide  the  Company  with up to $13 million in
research and development  funding.  The initial term of the funded research will
be three years,  subject to earlier termination or extension upon achievement of
certain  benchmarks  upon mutual  agreement of the parties.  The Company is also
entitled  to  receive up to $69.2  million in  milestones  upon  achievement  of
certain research, development and regulatory events.

     In  addition,   under  certain  circumstances  the  Company  may  have  the
opportunity to co-promote  products with  Wyeth-Ayerst  in the United States and
Canada.  There can be no  assurance  that the Company and  Wyeth-Ayerst  will be
successful in research and drug  discovery  based on this  technology,  that any
pre-clinical and clinical drug candidates  arising from the  collaboration  will
generate commercial product candidates that have viable clinical, regulatory and
intellectual  property profiles or that any commercial products arising from the
collaboration will enjoy market acceptance. Therefore, there can be no assurance
that any  milestones or royalty  income will be payable to the Company under its
agreement with Wyeth-Ayerst.

NEUROSCIENCE PHARMA INC.

    In March 1996,  Neurocrine  formed  Neuroscience  Pharma,  Inc.  ("NPI"),  a
research and development company.  Neurocrine licensed to NPI certain technology
and Canadian  marketing rights to the Company's  Neurosteroid and  Neurogenomics
programs in exchange for 49% of the outstanding  Common Stock of NPI. A group of
Canadian  institutional  investors invested approximately $9.5 million in NPI in
exchange for  Preferred  Stock of NPI,  which could be  exchanged  for shares of
Neurocrine's  Common Stock.  During 1997 and 1998 these  investors  redeemed the
Preferred  Stock for an  aggregate  of  1,279,758  shares of Common Stock of the
Company.  Pursuant to a Research and  Development  Agreement with a wholly owned
subsidiary of the Company,  NPI committed to expend an aggregate  amount of $9.5
million  for  clinical  development  of DHEA,  a  neurosteroid  for  Alzheimer's
Disease.  The DHEA Neurosteroid Program was discontinued in March 1999 following
results from the Phase  II/III  trial.  Despite  suggestion  of efficacy  from a
previously  completed 60 patient Phase II trial, the results of its Phase II/III
trial did not demonstrate a difference in efficacy between patients treated with
DHEA  versus  placebo.  Based on these  results,  NPI has  discontinued  further
development  of DHEA.  NPI will continue its research  activities in the area of
neurogenomics.  Pursuant to such  Research  and  Development  Agreement,  NPI is
entitled to receive  royalties on sales of products  developed in these programs
as well as exclusive  Canadian  marketing  rights for such products in the event
that the Company has not  terminated  the  technology  license and the marketing
rights. In connection with their initial  investment in NPI, such investors also
received  warrants  exercisable for 383,875 shares of the Company's Common Stock
and are eligible to receive additional  warrants in the future in the event that
NPI receives certain Canadian government incentives for research activities.



RISK FACTORS

DEPENDENCE ON STRATEGIC ALLIANCES

     The Company is dependent  upon its corporate  partners to provide  adequate
funding for certain of its  programs.  Under these  arrangements,  the Company's
corporate  partners are responsible  for (i) selecting  compounds for subsequent
development as drug candidates, (ii) conducting preclinical testing and clinical
trials and obtaining  required  regulatory  approvals for such drug  candidates,
and/or (iii) manufacturing and  commercializing any resulting drugs.  Failure of
these  partners to select a compound  discovered  by the Company for  subsequent
development into marketable products, gain the requisite regulatory approvals or
successfully  commercialize products would have a material adverse effect on the
Company's business, financial condition and results of operations. The Company's
strategy for  development  and  commercialization  of certain of its products is
dependent   upon   entering   into   additional   arrangements   with   research
collaborators, corporate partners and others, and upon the subsequent success of
these third parties in performing their  obligations.  There can be no assurance
that the Company will be able to enter into  additional  strategic  alliances on
terms favorable to the Company,  or at all. Failure of the Company to enter into
additional  strategic  alliances  would  have a material  adverse  effect on the
Company's business, financial condition and results of operations.

     The  Company  cannot  control the amount and timing of  resources  that its
corporate  partners devote to the Company's programs or potential  products.  If
any of the Company's  corporate  partners breach or terminate  their  agreements
with the Company or otherwise fail to conduct their collaborative  activities in
a  timely   manner,   the   preclinical   testing,   clinical   development   or
commercialization of product candidates will be delayed, and the Company will be
required   to  devote   additional   resources   to  product   development   and
commercialization,  or terminate  certain  development  programs.  The Company's
strategic alliances with Janssen,  Novartis, Lilly, and Wyeth-Ayerst are subject
to termination by Janssen, Novartis, Lilly, or Wyeth-Ayerst, respectively. There
can be no assurance that Janssen,  Novartis,  Lilly,  or  Wyeth-Ayerst  will not
elect  to  terminate  its  strategic  alliance  with  the  Company  prior to its
scheduled expiration.  In addition, if the Company's corporate partners effect a
merger  with a  third  party,  there  can be no  assurance  that  the  strategic
alliances will not be terminated or otherwise materially adversely affected. The
termination of any current or future  strategic  alliances could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.  Neurocrine's  corporate partners may develop,  either alone or with
others,  products  that  compete  with  the  development  and  marketing  of the
Company's  products.  Competing  products,  either  developed  by the  corporate
partners or to which the  corporate  partners  have rights,  may result in their
withdrawal  of  support  with  respect  to all  or a  portion  of the  Company's
technology,  which  would  have a  material  adverse  effect  on  the  Company's
business,  financial  condition  and  results  of  operations.  There  can be no
assurance  that  disputes  will not  arise in the  future  with  respect  to the
ownership  of rights to any  products or  technology  developed  with  corporate
partners.  These and other possible disagreements between corporate partners and
the Company could lead to delays in the collaborative  research,  development or
commercialization  of certain  product  candidates or could require or result in
litigation or  arbitration,  which would be  time-consuming  and expensive,  and
would  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.

MANUFACTURING

     The Company has in the past  utilized,  and intends to continue to utilize,
third party  manufacturing  for the  production  of material for use in clinical
trials and for the potential  commercialization of future products.  The Company
has no experience in manufacturing products for commercial purposes and does not
have any manufacturing facilities. Consequently, the Company is solely dependent
on contract  manufacturers  for all production of products for  development  and
commercial purposes. In the event that the Company is unable to obtain or retain
third-party manufacturing,  it will not be able to commercialize its products as
planned.  The  manufacture  of the  Company's  products for clinical  trials and
commercial  purposes is subject to cGMP  regulations  promulgated by the FDA. No
assurance can be given that the Company's third-party  manufacturers will comply
with cGMP regulations or other regulatory requirements now or in the future. The
Company's  current  dependence  upon third  parties for the  manufacture  of its
products may adversely  affect its profit margin,  if any, on the sale of future
products and the Company's  ability to develop and deliver  products on a timely
and competitive basis.

MARKETING, SALES, AND PHARMACEUTICAL PRICING ISSUES

     Neurocrine has retained certain  marketing or co-promotion  rights in North
America to its products under development,  and plans to establish its own North
American  marketing  and  sales  organization.  The  Company  currently  has  no
experience in marketing or selling  pharmaceutical  products and does not have a
marketing  and sales  staff.  In order to  achieve  commercial  success  for any
product  candidate  approved  by the  FDA,  Neurocrine  must  either  develop  a
marketing  and sales  force or enter into  arrangements  with  third  parties to
market and sell its products.  There can be no assurance  that  Neurocrine  will
successfully  develop  such  experience  or that it will be able to  enter  into
marketing and sales  agreements  with others on acceptable  terms, if at all. If
the Company develops its own marketing and sales  capabilities,  it will compete
with other companies that currently have  experienced and well funded  marketing
and sales operations. To the extent that the Company enters into co-promotion or
other marketing and sales arrangements with other companies,  any revenues to be
received by Neurocrine will be dependent on the efforts of others, and there can
be no assurance that such efforts will be successful.

     The  Company's  business  may  be  materially  adversely  affected  by  the
continuing efforts of government and third party payers to contain or reduce the
costs of health care through  various  means.  For example,  in certain  foreign
markets, pricing or profitability of prescription  pharmaceuticals is subject to
government  control.  In the United  States,  there have been,  and the  Company
expects that there will continue to be, a number of federal and state  proposals
to implement similar government control in such jurisdictions.  In addition,  an
increasing  emphasis  on  managed  care in the United  States has put,  and will
continue to put,  pressure  on  pharmaceutical  pricing.  Such  initiatives  and
proposals,  if adopted,  could decrease the price that the Company  receives for
any products it may develop and sell in the future,  and thereby have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.  Further,  to the extent that such proposals or  initiatives  have a
material  adverse  effect  on  other  pharmaceutical  companies  that  corporate
partners  or  prospective  corporate  partners  for  certain  of  the  Company's
potential  products,  the  Company's  ability  to  commercialize  its  potential
products may be materially adversely affected.

     The Company's ability to commercialize  pharmaceutical  products may depend
in part on the extent to which  reimbursement for the costs of such products and
related  treatments  will be available  from  government  health  administration
authorities,  private health insurers and other third-party payers.  Significant
uncertainty exists as to the reimbursement  status of newly approved health care
products, and third-party payers are increasingly challenging the prices charged
for  medical  products  and  services.  There  can  be  no  assurance  that  any
third-party  insurance  coverage  will be available to patients for any products
developed  by  the  Company.   Government  and  other  third-party   payors  are
increasingly  attempting to contain  health care costs by limiting both coverage
and the level of reimbursement for new therapeutic products, and by refusing, in
some  cases,  to provide  coverage  for uses of  approved  products  for disease
indications for which the FDA has not granted  marketing  approval.  If adequate
coverage and reimbursement levels are not provided by government and third party
payors for the Company's products, the market acceptance of these products would
be materially adversely affected.

COMPETITION

     The  biotechnology and  pharmaceutical  industries are subject to rapid and
intense  technological  change.  The Company  faces,  and will continue to face,
competition  in the  development  and marketing of its product  candidates  from
academic   institutions,   government   agencies,   research   institutions  and
biotechnology  and  pharmaceutical  companies.  Competition may arise from other
drug development  technologies,  methods of preventing or reducing the incidence
of disease,  including  vaccines,  and new small  molecule  or other  classes of
therapeutic  agents.  There can be no assurance that developments by others will
not  render  the  Company's  product  candidates  or  technologies  obsolete  or
noncompetitive.

     Betaseron and Avonex,  similar forms of beta-interferon  marketed by Berlex
BioSciences  and Biogen,  Inc.,  respectively,  and  Copaxone a peptide  polymer
marketed by Teva,  have been approved for the marketing in the United States and
certain  other  countries  for the  treatment  of relapsing  remitting  multiple
sclerosis.  Tacrine,  marketed by Warner-Lambert  Co., and Aricept,  marketed by
Pfizer Inc, have been approved for the treatment of Alzheimer's dementia.  Sales
of these drugs may reduce the available market for any product  developed by the
Company  for these  indications.  The  Company is  developing  products  for the
treatment  of  anxiety  disorders,  which  will  compete  with  well-established
products in the benzodiazepine class,  including Valium,  marketed by Hoffman-La
Roche, Inc., and depression,  which will compete with well-established  products
in the  anti-depressant  class,  including  Prozac,  marketed by Eli Lilly & Co.
Certain technologies under development by other  pharmaceutical  companies could
result in treatments for these and other diseases and disorders being pursued by
the Company.  For  example,  a number of companies  are  conducting  research on
molecules to block CRF to treat anxiety and depression.  Other biotechnology and
pharmaceutical companies are developing compounds to treat obesity. In the event
that one or more of these products and/or  programs are  successful,  the market
for the Company's products may be reduced or eliminated.

     In addition,  if Neurocrine receives regulatory approvals for its products,
manufacturing efficiency and marketing capabilities are likely to be significant
competitive  factors.  At  the  present  time,   Neurocrine  has  no  commercial
manufacturing capability, sales force or marketing experience. In addition, many
of the  Company's  competitors  and  potential  competitors  have  substantially
greater capital resources, research and development resources, manufacturing and
marketing  experience and production  facilities than does  Neurocrine.  Many of
these  competitors  also  have   significantly   greater  experience  than  does
Neurocrine  in  undertaking  preclinical  testing  and  clinical  trials  of new
pharmaceutical products and obtaining FDA and other regulatory approvals.

PATENTS AND PROPRIETARY RIGHTS

     The Company  files  patent  applications  both in the United  States and in
foreign countries,  as it deems  appropriate,  for protection of its proprietary
technology and products.  As of December 31, 1998, 4 patents have been issued to
the Company;  and the Company has  received  licenses to 5 issued  patents.  The
Company  owns or has  exclusive  rights to a total of  approximately  122 patent
applications   pursuant  to  license   agreements  with  academic  and  research
institutions,  including the Beckman Research Institute of the City of Hope, the
Salk Institute for Biological  Studies,  and Leland Stanford Junior  University.
The Company  intends to file additional  United States and foreign  applications
and  license  additional  technologies  from  third  parties  in the  future  as
appropriate.  However,  there can be no assurances  that licenses to third party
technologies  that may be required  by or  advantageous  to the Company  will be
obtained on commercially reasonable terms or at all.

     The  Company's  success  will  depend  on  its  ability  to  obtain  patent
protection for its products,  preserve its trade secrets,  prevent third parties
from infringing upon its proprietary rights, and operate without infringing upon
the proprietary rights of others, both in the United States and internationally.

     Because  of the  substantial  length of time and  expense  associated  with
bringing new products through the development and regulatory  approval processes
in  order  to  reach  the  marketplace,   the  pharmaceutical   industry  places
considerable  importance on obtaining patent and trade secret protection for new
technologies,  products and processes.  Accordingly, the Company intends to seek
patent protection for its proprietary technology and compounds.  There can be no
assurance as to the success or timeliness  in obtaining  any such patents,  that
the breadth of claims obtained,  if any, will provide adequate protection of the
Company's proprietary technology or compounds,  or that the Company will be able
to adequately enforce any such claims to protect its proprietary  technology and
compounds. Since patent applications in the United States are confidential until
the patents  issue,  and  publication of discoveries in the scientific or patent
literature tend to lag behind actual  discoveries by several months, the Company
cannot be certain that it was the first creator of inventions covered by pending
patent  applications  or that it was the first to file patent  applications  for
such  inventions.  Litigation,  which could  result in  substantial  cost to the
Company, may be necessary to enforce the Company's patent and license rights.

     The degree of patent protection  afforded to  pharmaceutical  inventions is
uncertain and any patents that may issue with regard to the Company's  potential
products  will be subject to this  uncertainty.  There can be no assurance  that
competitors  will not develop  competitive  products outside the protection that
may be afforded by the claims of the Company's patents. Other potential products
that the Company may develop may not consist of novel  compounds  and  therefore
would not be covered by composition of matter patent  claims.  In addition,  the
Company is aware of a number of patent applications, both domestic and European,
relating to neurological  compounds,  and in particular CRF receptor  antagonist
potential  therapeutics,  that have  been  filed by or are  controlled  by other
entities,  including competitors and potential competitors of the Company. There
can be no assurance that the Company's  potential products can be commercialized
without a license to any patents which may issue from such applications.

     The Company may be  required to obtain  licenses to patents or  proprietary
rights of others.  As the  biotechnology  industry  expands and more patents are
issued,  the risk increases that the Company's  potential products may give rise
to claims that such products  infringe the patent rights of others. At least one
patent containing  claims covering  compositions of matter consisting of certain
altered  peptide ligand  therapeutics  for use in modulating the immune response
has  issued in  Europe,  and the  Company  believes  that this  patent  has been
licensed to a competitor of the Company. There can be no assurance that a patent
containing  corresponding  claims will not issue in the United States.  Although
the Company is engaged in an opposition  proceeding with respect to the European
patent,  there can be no guarantee  that the Company will be  successful in this
opposition.  Further,  there can be no assurance that the claims of the European
patent or any corresponding  claims of any future United States patents or other
foreign patents which may issue will not be infringed by the manufacture, use or
sale of any  potential  altered  peptide  ligand  therapeutics  developed by the
Company or Novartis.  Although the Company has been granted claims to a European
patent covering altered peptide ligand  therapeutics,  there can be no assurance
that the Company or Novartis would prevail in any legal action  seeking  damages
or  injunctive  relief for  infringement  of any such  claims or any patent that
might issue under such  applications or that any license required under any such
patent  would  be made  available  or,  if  available,  would  be  available  on
acceptable terms. Failure to obtain a required license could prevent the Company
and Novartis from  commercializing any altered peptide ligand products that they
may develop.

     The Company is aware of an issued U.S. patent directed toward an excitatory
amino acid  transporter  included  within the  subject  matter of its  corporate
collaboration with  Wyeth-Ayerst.  Although the Company believes that it will be
found  to have  superior  rights  to this  transporter  through  an  anticipated
interference  proceeding,  there can be no  assurance  that the Company  will be
successful in such an interference.

     In 1998 a patent  application  filed by a third party outside of the United
States pursuant to the Patent Cooperation Treaty was published claiming priority
from a United States patent application and came to the attention of the Company
and   Janssen,    the   Company's    corporate   partner   in   the   field   of
corticotropin-releasing  factor antagonists.  This application claims a genus of
chemical  compounds  that includes the lead product  candidate  currently  under
development by Janssen.  This  application  appears to predate the filing by the
Company and Janssen with respect to such  compound.  The Company and Janssen are
engaged  in  discussions  with  the  third  party  with  regard  to a  licensing
arrangement.  There can be no assurance that such discussions will be successful
or that such a license will be available on  commercially  reasonable  terms. If
the third party's patent application was determined to predate the filing by the
Company and Janssen and were to issue in its current form, Janssen may be unable
to  commercialize  the current lead  compound in the  countries  which the third
party patent issues and may elect to select a new lead clinical candidate. While
the Company  and Janssen  have filed  patent  applications  directed to chemical
compounds not covered by the third party's application,  selection of a new lead
clinical candidate may delay the Company's  realization of milestone and royalty
income under its agreement with Janssen. As noted above, the patent positions of
pharmaceutical  and  biotechnology  companies,  including  the Company,  involve
complex legal and factual  issues.  It is not certain that,  with respect to the
United  States,  the third  party's date of invention  will pre-date that of the
Company,  that outside of the United States the third party's patent application
will be  determined  to predate  filing by the  Company  and Janssen or that the
third  party  application  will  issue as a patent.  In  addition,  if the third
party's patent does  eventually  issue, it is not certain that the form in which
it issues will present an impediment to Janssen's CRF antagonist development and
commercialization  program  or lead to delays in the  Company's  realization  of
milestone and royalty income derived  therefrom.  The Company's  independent CRF
antagonist  program is not impacted  and will  continue  without  regard to this
application.

     No assurance can be given that any licenses  required  under any patents or
proprietary  rights of third parties would be made available on terms acceptable
to the  Company,  or at all. If the Company  does not obtain such  licenses,  it
could  encounter  delays in product  introductions  while it  attempts to design
around such patents, or could find that the development,  manufacture or sale of
products  requiring  such  licenses  could  be  foreclosed.  Litigation  may  be
necessary  to defend  against or assert such claims of  infringement  to enforce
patents  issued to the Company to protect trade secrets or know-how owned by the
Company,  or to determine  the scope and validity of the  proprietary  rights of
others.  In addition,  interference  proceedings  declared by the United  States
Patent and  Trademark  Office may be  necessary  to  determine  the  priority of
inventions with respect to patent  applications of the Company or its licensors.
Litigation or interference  proceedings could result in substantial costs to and
diversion of effort by, and may have a material  adverse impact on, the Company.
In addition,  there can be no assurance  that these efforts by the Company would
be successful.

     The Company also relies upon  unpatented  trade  secrets and  improvements,
unpatented  know-how  and  continuing  technological  innovation  to develop and
maintain  its  competitive  position,  which it seeks to  protect,  in part,  by
confidentiality   agreements  with  its  commercial   partners,   collaborators,
employees and consultants.  The Company also has invention or patent  assignment
agreements with its employees and certain,  but not all, commercial partners and
consultants.  There can be no assurance  that a person not bound by an invention
assignment  agreement  will not  develop  relevant  inventions.  There can be no
assurance that binding  agreements will not be breached,  that the Company would
have adequate  remedies for any breach, or that the Company's trade secrets will
not otherwise become known or be independently discovered by competitors.

     As is  commonplace  in the  biotechnology  industry,  the  Company  employs
individuals   who  were   previously   employed   at  other   biotechnology   or
pharmaceutical companies,  including competitors or potential competitors of the
Company.  To the extent such Company employees are involved in research areas at
the  Company  which are  similar to those  areas in which they were  involved at
their former employer,  the Company may be subject to claims that such employees
and/or the Company have inadvertently or otherwise used or disclosed the alleged
trade  secrets  or  other  proprietary  information  of  the  former  employers.
Litigation may be necessary to defend against such claims, which could result in
substantial  costs  and be a  distraction  to  management,  and which may have a
material  adverse  effect on the Company,  even if the Company was successful in
defending such claims.

GOVERNMENT REGULATION

     Regulation  by  government  authorities  in the United  States and  foreign
countries is a significant factor in the development,  manufacture and marketing
of the  Company's  proposed  products  and in its ongoing  research  and product
development  activities.  All of the Company's  products will require regulatory
approval by government agencies prior to commercialization. In particular, human
therapeutic  products are subject to rigorous  preclinical  testing and clinical
trials  and  other  approval  procedures  of  the  FDA  and  similar  regulatory
authorities  in  foreign  countries.  Various  federal  and state  statutes  and
regulations also govern or influence testing,  manufacturing,  safety, labeling,
storage and  record-keeping  related to such products and their  marketing.  The
process of obtaining these approvals and the subsequent  substantial  compliance
with  appropriate  federal  and  state  statutes  and  regulations  require  the
expenditure  of  substantial  time and financial  resources.  Any failure by the
Company or its  collaborators or licensees to obtain,  or any delay in obtaining
or maintaining,  regulatory approval could adversely affect the marketing of any
products  developed  by the Company,  its ability to receive  product or royalty
revenues and its liquidity and capital resources.

     Preclinical  testing  is  generally  conducted  in  laboratory  animals  to
evaluate  the  potential  safety and the  efficacy of a product.  The results of
these  studies  are  submitted  to the FDA as a part of an  IND,  which  must be
approved  before  clinical  trials  in humans  can  begin.  Typically,  clinical
evaluation involves a time consuming and costly three-phase process. In Phase I,
clinical  trials are conducted  with a small number of subjects to determine the
early safety profile, the pattern of drug distribution and metabolism.  In Phase
II,  clinical  trials are  conducted  with groups of patients  afflicted  with a
specific disease in order to determine preliminary efficacy, optimal dosages and
expanded   evidence  of  safety.  In  Phase  III,   large-scale,   multi-center,
comparative  trials are conducted with patients  afflicted with a target disease
in order to provide enough data to  demonstrate  with  substantial  evidence the
efficacy and safety  required by the FDA. The FDA closely  monitors the progress
of each of the three  phases of  clinical  trials  and may,  at its  discretion,
re-evaluate,  alter,  suspend or terminate the testing based upon the data which
have been accumulated to that point and its assessment of the risk/benefit ratio
to the patient.

     The results of preclinical testing and clinical trials are submitted to the
FDA in the form of an NDA or BLA for approval to commence  commercial  sales. In
responding  to an NDA or BLA,  the FDA may  grant  marketing  approval,  request
additional  information or deny the  application if the FDA determines  that the
application does not satisfy its regulatory  approval criteria.  There can be no
assurance  that  approvals  will be  granted on a timely  basis (or at all).  If
approved,  there can be no assurance that such approval will include  acceptable
labeling to adequately  commercialize the product. Similar regulatory procedures
must also be complied with in countries outside the United States.

     To date,  the  Company  or its  collaborators  have  submitted  five IND or
equivalent  applications in the United States,  Canada and/or Europe with regard
to its product candidates and has commenced clinical trials. Even if Canadian or
European  regulatory  authorities  approve  the  product,  the  Company  will be
required  to  undertake  additional  clinical  testing to obtain FDA  regulatory
approval in the United  States.  No assurance can be given that the Company will
be  able  to  obtain  FDA or  other  governmental  regulatory  approval  for any
products.

     Neurocrine  currently  has  five  programs  in  clinical  development.  The
Company's  CRF  receptor  antagonist  project is  currently in Phase II clinical
development with its partner,  Janssen  Pharmaceutica,  for  anxiety/depression.
Neurocrine  and its partner,  Novartis  Pharmaceuticals,  are  conducting  their
second Phase II clinical trial with  Neurocrine's  APL compound in patients with
multiple  sclerosis.  Neurocrine  is  conducting a Phase I/II trial with an IL-4
Fusion Toxin for  glioblastoma  (malignant  brain tumors).  The Company has also
completed a Phase Ib clinical trial for insomnia and recently  announced that it
commenced  a Phase I  safety  and dose  escalating  clinical  study  for and APL
compound for Type I diabetics.

     The results from  preclinical  testing and early clinical trials may not be
predictive of results obtained in later clinical trials. As a result,  there can
be no assurance that clinical  trials  conducted by the Company or its corporate
partners will demonstrate sufficient safety and efficacy to obtain the requisite
regulatory  approvals  or will  result  in  marketable  products  or  marketable
indications.  In addition,  late stage clinical  trials are often conducted with
patients  having  the most  advanced  stages of  disease.  During  the course of
treatment,  these patients can die or suffer other adverse  medical  effects for
reasons  that may not be related to the  pharmaceutical  agent being  tested but
which can  nevertheless  adversely  affect  clinical trial results.  A number of
companies in the  biotechnology  and  pharmaceutical  industries  have  suffered
significant  setbacks in advanced clinical trials,  even after promising results
in earlier trials. If the Company's drug candidates are not shown to be safe and
effective in clinical trials, the resulting delays in developing other compounds
and conducting related  preclinical  testing and clinical trials, as well as the
potential need for additional financing, would have a material adverse effect on
the Company's business, financial condition and results of operations.

     The rate of completion of clinical  trials  conducted by the Company or its
corporate  partners  may be  delayed  by many  factors,  including  slower  than
expected  patient  recruitment or unforeseen  safety  issues.  Any delays in, or
termination  of, the  Company's  clinical  trials would have a material  adverse
effect on the Company's business, financial condition and results of operations.
There can be no assurance  that  Neurocrine  or its  corporate  partners will be
permitted  by  regulatory  authorities  to  undertake  clinical  trials  for its
products or, if such trials are  conducted,  that any of the  Company's  product
candidates  will prove to be safe and  efficacious  or will  receive  regulatory
approvals.

     The Company is required to conduct its research  activities  in  compliance
with good laboratory practice  regulations  enforced by FDA. The Company is also
subject  to   various   Federal,   state  and  local   laws,   regulations   and
recommendations  relating to safe working conditions,  laboratory  manufacturing
practices,  and the use and  disposal  of  hazardous  or  potentially  hazardous
substances,  including radioactive compounds and infectious disease agents, used
in connection with the Company's research.  The extent of government  regulation
that might result from future  legislation  or  administrative  action cannot be
predicted accurately.

agreements that contain  confidentiality  provisions and restrict the members of
the  Scientific  Advisory  Board from competing with the Company for the term of
the agreement.  Each member of the Scientific  Advisory Board receives  either a
per diem  consulting  fee or a retainer fee. Each member also has received stock
or stock  options  in the  Company,  which vest over  time.  All  members of the
Scientific  Advisory  Board are full-time  employees of a university or research
institute  that has  regulations  and  policies  which limit the ability of such
personnel  to act as  part-time  consultants  or in  other  capacities  for  any
commercial  enterprise,  including the Company. A change in these regulations or
policies could  adversely  affect the  relationship  of the Scientific  Advisory
Board member with the Company.

INSURANCE

     The Company maintains product liability  insurance for clinical trials. The
Company  intends  to  expand  its  insurance  coverage  to  include  the sale of
commercial   products  if  marketing   approval  is  obtained  for  products  in
development. However, insurance coverage is becoming increasingly expensive, and
no assurance  can be given that the Company  will be able to maintain  insurance
coverage at a reasonable  cost or in  sufficient  amounts to protect the Company
against losses due to liability. There can also be no assurance that the Company
will be able to obtain  commercially  reasonable product liability insurance for
any products  approved for marketing.  A successful  product  liability claim or
series of claims  brought  against  the  Company  could have a material  adverse
effect on its business, financial condition and results of operations.

EMPLOYEES


     As of December 31, 1998, the Company had 149  employees,  consisting of 135
full-time and 14 part-time employees. Of the full-time employees, 46 hold Ph.D.,
M.D., or equivalent degrees.  None of the Company's employees are represented by
a collective bargaining  arrangement,  and the Company believes its relationship
with its  employees is good.  The Company is highly  dependent on the  principal
members of its management and scientific  staff.  The loss of services of any of
these  personnel  could  impede the  achievement  of the  Company's  development
objectives. Furthermore, recruiting and retaining qualified scientific personnel
to perform  research and development work in the future will also be critical to
the Company's  success.  There can be no assurance that the Company will be able
to attract and retain personnel on acceptable terms given the competition  among
biotechnology,  pharmaceutical  and  health  care  companies,  universities  and
non-profit research institutions for experienced  scientists.  In addition,  the
Company  relies on members of its  Scientific  Advisory  Board and a significant
number of  consultants  to assist the Company in  formulating  its  research and
development strategy.


ITEM 2.  PROPERTIES


     The  Company  leases  approximately  93,000  square  feet of  space  at its
headquarters  facility,  of which  approximately  80% is  laboratory  facilities
dedicated to research and development.  The facility was constructed in 1998 and
is under lease through August 2013. The Company has sublet  approximately 13,000
square feet of this  facility  through  August 2000.  In  addition,  the Company
leases  approximately  19,000 square feet of laboratory and office space,  which
has been sublet to a third party. The lease and sublease on this property expire
in June 2000. The Company's facilities are located in San Diego, California.


     The Company  believes that its property and  equipment  are generally  well
maintained, in good operating condition and adequate for its current needs.

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

     The following  Management's  Discussion and Analysis of Financial Condition
and Results of Operations of Neurocrine  Biosciences,  Inc. ("Neurocrine" or the
"Company"),  as well as the  preceding  sections of this  Annual  Report on Form
10-K, contain forward-looking  statements which involve risks and uncertainties,
pertaining generally to the expected continuation of the Company's collaborative
agreements,  the receipt of research payments thereunder, the future achievement
of various milestones in product development and the receipt of payments related
thereto,  the  potential  receipt of royalty and  profit-sharing  payments,  the
anticipated dates of commencement of selection of development candidates and the
commencement of clinical  trials,  the successful  continuation of the Company's
research  and  development  programs  and the  potential  development  of future
products,  the period of time the Company's existing capital resources will meet
its funding  requirements,  and the Company's  financial  results of operations.
Actual  results  could  differ   materially  from  those   anticipated  in  such
forward-looking  statements as a result of various factors,  including those set
forth below, and those outlined in the Business section of Item 1.


Overview

     Since the  founding of the  Company in January  1992,  Neurocrine  has been
engaged in the discovery and  development of novel  pharmaceutical  products for
diseases  and  disorders  of the central  nervous and immune  systems.  To date,
Neurocrine  has not generated  any revenues from the sale of products,  and does
not expect to generate any product  revenues  for the  foreseeable  future.  The
Company's revenues are expected to come from its strategic alliances. Neurocrine
has incurred a cumulative  deficit of  approximately  $25 million as of December
31, 1998 and expects to incur additional  operating losses in the future,  which
are potentially greater than losses in prior years.


Results of Operations

     The  Company's   revenue  from   collaborative   research  and  development
agreements  was $16.0 million for the year ended December 31, 1998 compared with
$26.1 million in 1997,  and $19.2 million in 1996.  The decline in 1998 revenues
compared to 1997 revenues resulted  primarily from  non-recurring  1997 revenues
related to the  completion  of the  sponsored  research  portion of the  Janssen
collaboration,  a one-time research support payment received under the Eli Lilly
collaboration,  sponsored  development  payments  received  under  the  Novartis
collaboration and the timing of milestone  achievements received under all three
collaborations.  Revenues in 1998 included $3.6 million of sponsored development
received  from the  Company's  Canadian  affiliate,  NPI.  The  increase in 1997
revenues  compared to 1996 revenues  resulted  primarily to increased  sponsored
research,  license fees and  milestone  revenues  recognized  under the Janssen,
Novartis and Eli Lilly collaborations.

     Research and  development  expenses  increased to $21.8 million during 1998
compared with $18.8 million in 1997 and $12.6 million in 1996.  These  increases
reflect higher costs  associated  with the addition of scientific  personnel and
costs to advance  compounds into  preclinical and clinical  trials.  The Company
expects  to incur  significant  increases  in future  periods as  compounds  are
advanced through the clinical development process.

     General and  administrative  expenses increased to $6.6 million during 1998
compared  with $5.7  million in 1997 and $3.7 million in 1996.  These  increases
resulted   primarily  from   additional   administrative   personnel,   business
development and professional  service expenses to support the expanded  clinical
development  efforts.  The Company  anticipates  slight increases in general and
administrative  expenses  over  the next few  years  as the  Company's  clinical
efforts continue to expand.

     During  1998,  the  Company  wrote-off  acquired  in-process  research  and
development costs of $4.9 million. In May 1998, the Company acquired the assets,
liabilities and the in-process  research and  development  programs of Northwest
NeuroLogic,  Inc.  ("NNL") in  exchange  for  Company's  Common  Stock and stock
options valued at $4.2 million. The acquired in-process research and development
consisted of  Melanocortin  ("MCR"),  a brain  receptor  technology  relating to
obesity and Excitatory Amino Acid Transporters  ("EAATs"), a technology relating
to  neurodegeneration  and stroke. In June 1998, the Company purchased  licenses
for the use of technology in programs  relating to insomnia  ("NBI-34060")  from
DOV  Pharmaceuticals  and brain cancer ("IL-4  Fusion  Toxin") from the National
Institute  of  Health  for  $710,000.   The  acquired  in-process  research  and
development  projects and the licensed  technologies  are in the early stages of
development,  have  not  reached  technological  feasibility  and  have no known
alternative uses.

     The nature and efforts required to develop the acquired in-process research
and development  into  commercially  viable products  include  completion of the
development  stages of a  compound,  pre-clinical  development,  clinical  trial
testing,  FDA  approval  and  commercialization.   Due  to  the  nature  of  the
pharmaceutical   development   process,   the  Company   anticipates   incurring
substantial costs to develop the compounds into products.  However,  there is no
certainty  that any of these  development  efforts  will result in  commercially
viable  products.  During the  upcoming  fiscal  year,  the Company  anticipates
research and development  expenditures  of $2.8 million for EAATs,  $1.7 million
for MCR, $6.1 million for IL-4 Fusion Toxin and $5.0 million for NBI-34060.

     The  value  of  the  acquired   in-process  research  and  development  was
determined by estimating  the projected net cash flows related to such products,
including  costs to complete the  development,  and future revenues to be earned
upon commercialization of the products. These cash flows were discounted back to
their net present value using a discount factor of 35%. The resulting  projected
net cash  flows  from such  projects  were based on  management's  estimates  of
revenues  and  operating  profits  related  to such  projects.  Management  also
reviewed the probability of product success,  which were estimated using certain
probability factors for each stage of development.

     Interest  income  increased to $4.2 million  during 1998 compared with $4.1
million for 1997 and $2.9  million in 1996.  The  increase  over 1997  primarily
resulted  from higher  effective  interest  yields on the  Company's  investment
portfolio  during 1998.  The increase over 1996  primarily  resulted from higher
effective interest yields in addition to higher average cash balances throughout
the year.  Management  anticipates  lower  interest  income in future periods as
clinical  efforts  increase  operating   requirements  and  cash  available  for
investment declines.

     Equity in NPI losses recorded in 1998 were $3.4 million  compared with $1.1
million  in 1997.  In  addition  to the equity in NPI losses  during  1998,  the
Company  recorded a write-down in the value of its  investment in NPI,  totaling
$3.8 million.

     Net loss for 1998 was $20.0  million  or $1.10 per  share  compared  to net
income of $5.1 million or $0.30 per share for 1997 and $5.9 million or $0.39 per
share in 1996.  Management  expects  to incur  substantial  operating  losses in
future periods as its clinical development efforts continue to grow.

     To date, the Company's  revenues have come principally from funded research
and  achievements of milestones under corporate  collaborations.  The nature and
amount  of  these  revenues  from  period  to  period  may  lead to  substantial
fluctuations in the results of year-to-date revenues and earnings.  Accordingly,
results and earnings of one period are not predictive of future periods.

LIQUIDITY AND CAPITAL RESOURCES

     As of  December  31,  1998,  the  Company had cash,  cash  equivalents  and
short-term  investments  of $62.7 million.  The Company  invests its excess cash
primarily in investment  grade debt  instruments,  marketable debt securities of
U.S.  government  agencies  and  high-grade  commercial  paper.  Management  has
established  guidelines relative to diversification and maturities that maintain
safety and liquidity.  The primary market risk associated with such  investments
is  vulnerability  to changes in short-term  and long-term  U.S.  prime interest
rates. For further information regarding the Company's investments,  see Notes 1
and 3 of the Notes to the Consolidated Financial Statements.

     Net  cash  used by  operating  activities  during  1998 was  $10.7  million
compared  with net cash  provided of $11.0  million in 1997 and $6.7  million in
1996.  The increase in cash used in  operations  during 1998 compared with 1997,
resulted  primarily from  increased  sponsored  research and milestone  revenues
received under the Company's  collaborations during 1997 and an increase in 1998
operating expenses as the Company expands its clinical  development  activities.
The increase in cash provided during 1997 compared with 1996, resulted primarily
from  increased  sponsored  research and milestone  revenues  received under the
Company's collaborations during 1997.

     Net cash  provided by  investing  activities  during 1998 was $4.7  million
compared  with net cash used of $7.2 million and $48.6 million in 1997 and 1996,
respectively.  The cash  provided by investing  activities  during 1998 resulted
primarily  from  sales of  short-term  investments.  The cash used in  investing
activities  during  1997  and 1996  resulted  from the  purchase  of  short-term
investments  with proceeds from the Company's  prior  financings and the sale of
Common Stock to corporate collaborators.

     Net cash  provided by  financing  activities  during 1998 was $1.9  million
compared  with $659,000 and $46.8  million  during 1997 and 1996,  respectively.
Cash provided  during 1998 resulted from proceeds  received  under capital lease
financing of equipment  purchases.  Cash provided  during 1997 resulted from the
issuance of the  Company's  Common Stock upon the exercises of stock options and
warrants and proceeds  received from a note payable used to finance the purchase
of land.  Cash provided  during 1996  resulted  from proceeds  received from the
Company's  initial  public  offering and sale of the  Company's  Common Stock to
corporate collaborators in May 1996.

     Neurocrine has primarily  financed its operations through proceeds received
from the sale of its Common Stock in various  private and public  offerings,  as
well as revenues received under corporate collaborations.

     In February  1995,  the  Company  entered  into a three year  collaborative
research  and  development  agreement  with Janssen for the  development  of CRF
receptor  antagonists  for the  treatment of anxiety,  depression  and substance
abuse.  Janssen paid the Company  $3.7  million and $3.0  million for  sponsored
research  during  1997  and  1996,  respectively.   Milestone  payments  totaled
$250,000,   $1.5  million  and  $1.0  million   during  1998,   1997  and  1996,
respectively.  The collaborative research portion of the agreement was completed
as  scheduled  in 1997  with  the  selection  of a  clinical  candidate  and the
commencement of clinical  trials in Europe.  The Company may continue to receive
milestone  payments  and  royalties  upon  the  successful  continuation  of the
development portion of the agreement.

     In January  1996,  the Company  entered into an agreement  with Novartis to
develop  altered  peptide  ligands  for the  treatment  of  multiple  sclerosis.
Novartis  paid the Company for license fees and research  funding  totaling $4.5
million,  $7.2  million  and $8.5  during  1998,  1997 and  1996,  respectively.
Milestone payments were $2.3 million, $3.8 million and $3.0 million during 1998,
1997 and 1996, respectively.

     In March 1996, the Company  participated in the formation of a research and
development company, Neuroscience Pharma, Inc. ("NPI"), with a group of Canadian
investors.  At the same time,  the Company  entered  into a  sponsored  research
agreement with NPI. The terms of the agreement called for NPI to fund additional
research  efforts on technologies  licensed to NPI by the Company.  During 1998,
the  Company  recognized  $3.6  million  in  revenues  associated  with costs of
research on the Neurogenomics and DHEA programs.

     In May 1997,  the Company  purchased  two  adjacent  parcels of land in San
Diego for  approximately  $5.0  million in cash.  One parcel was sold to Science
Park Center,  LLC. ("LLC"),  of which the Company owns a minority  interest,  in
exchange  for a note  receivable  of $3.5 million plus  interest.  However,  for
accounting purposes,  this transaction does not qualify as a sale under SFAS No.
98 and therefore,  the entire amount of the note receivable is included in land.
The amount  included in land at December  31, 1998 and 1997 was $3.8 million and
$3.5  million,  respectively.  During  1998,  the LLC  constructed  an  expanded
laboratory  and office  complex on the  property  and leased the facility to the
Company under a 15 year operating  lease. The Company has the option to purchase
the facility at any time during the lease at a predetermined  price. The Company
will hold the remaining  parcel until such time as the Company's growth requires
additional expansion.

     The Company  believes that its existing  capital  resources,  together with
interest income and future payments due under the strategic  alliances,  will be
sufficient to satisfy its current and projected  funding  requirements  at least
through the year 2000.  However,  no  assurance  can be given that such  capital
resources   and  payments  will  be  sufficient  to  conduct  its  research  and
development programs as planned. The amount and timing of expenditures will vary
depending upon a number of factors, including progress of the Company's research
and development programs.


INTEREST RATE RISK

     The  Company is exposed to changes in  interest  rates  primarily  from its
investments in certain  available-for-sale  securities and secondarily  from its
long-term debt.  Under its current  policies,  the Company does not use interest
rate derivative instruments to manage exposure to interest rate changes.

     The Company's  investments are primarily in fixed income,  investment-grade
securities and are not restricted.  The investment  policy  emphasizes return on
principal and liquidity and is focused on fixed returns,  which limit volatility
and risk of principal.  At December 31, 1998, the Company had available-for-sale
securities of $51.0 million. Interest risk exposure on long-term debt relates to
the Company's  note payable which bears of floating  interest rate of prime plus
one quarter percent (8.00% at December 31, 1998). At December 31, 1998, the note
balance  was  approximately  $610,000,  payable  in equal  monthly  installments
through January 2003. The Company  believes that a hypothetical  100 basis point
adverse move in interest rates along the entire  interest rate yield curve would
not materially effect the fair value of interest sensitive financial instruments
nor the costs associated with the long-term debt.


IMPACT OF YEAR 2000

     The Year 2000 Issue is the result of computer  programs being written using
two digits rather than four to define the applicable  year. Any of the Company's
computer  programs or  hardware  that have  date-sensitive  software or embedded
chips may  recognize  a date  using "00" as the year 1900  rather  than the year
2000.  This  could  result  in  a  system  failure  or  miscalculations  causing
disruptions of operations,  including, among other things, a temporary inability
to process  transactions,  send invoices,  or engage in similar normal  business
activities.

     Based on recent  assessments,  the Company  determined  that it will not be
required to modify or replace  significant  portions of hardware and software so
that those systems will properly  utilize  dates beyond  December 31, 1999.  The
Company presently  believes that with  modifications and replacement of existing
hardware and software,  the Year 2000 Issue can be mitigated.  However,  if such
modifications  and replacements are not made, or are not completed  timely,  the
Year 2000 Issue could have a material impact on the operations of the Company.

     The  Company's  plan to resolve the Year 2000 Issue  involves the following
four phases: assessment,  remediation,  testing, and implementation. To date the
Company  has  fully  completed  its  assessment  of all  systems  that  could be
significantly affected by the Year 2000. The completed assessment indicated that
most of the Company's significant  information  technology systems are Year 2000
compliant.  That assessment did,  however,  indicated that software and hardware
(embedded  chips)  used in some  scientific  equipment  were at  risk.  Affected
systems include several robotics  systems used for high  through-put  screening.
The Company is currently  assessing cost  comparisons on whether to remediate or
replace this equipment and expects to have the equipment corrected and re-tested
by May 1,  1999.  The  Company  has  gathered  information  about  the Year 2000
compliance status of its significant  suppliers and contractors and continues to
monitor their compliance.

     For its  information  technology  exposures,  to date  the  Company  is 99%
complete on the remediation phase and expects to complete software reprogramming
and replacement no later than April 15, 1999. To date, the Company has completed
100% of its testing and has  implemented  90% of its remediated  systems for its
scientific  equipment.  The  remediation  phase for all  significant  systems is
expected to be complete by May 1, 1999, with all remediated systems fully tested
by June 1, 1999.

     The Company has queried its important suppliers and contractors that do not
share  information  systems with the Company  (external  agents).  To date,  the
Company is not aware of any external agent Year 2000 issue that would materially
impact the company's  results of operations,  liquidity,  or capital  resources.
However,  the Company has no means of ensuring that external agents will be Year
2000  ready.  The  inability  of  external  agents to  complete  their Year 2000
resolution process in a timely fashion could materially impact the Company.  The
effect of non-compliance by external agents is not determinable.

     The Company will utilize both internal and external resources to reprogram,
or replace,  test and implement the software and  scientific  equipment for Year
2000  modifications.  The total cost of the Year 2000  project is  estimated  at
approximately $175,000 and is being funded through operating cash flows and
capital  equipment  financing.  To date, the Company has incurred  approximately
$100,000 related to all phases of the Year 2000 project.  Of the total remaining
project  costs,  approximately  $40,000 is  attributable  to the purchase of new
software, $25,000 for new scientific equipment,  which will be capitalized,  and
$10,000 for the repair of hardware and software.

     The Company  plans to  complete  the Year 2000  modifications  are based on
management's best estimates,  which were derived utilizing numerous  assumptions
of future events  including  continued  availability of certain  resources,  and
other factors. Estimates on the status of completion and the expected completion
dates are based on costs  incurred  to date  compared to total  expected  costs.
However,  there can be no guarantee  that these  estimates  will be achieved and
actual results could differ  materially from those plans.  Specific factors that
might  cause such  material  differences  include,  but are not  limited to, the
availability  and cost of personnel  trained in this area, the ability to locate
and correct all relevant computer codes, and similar uncertainties.

     The Company has not completed a formal contingency plan for non-compliance,
but it is developing a plan based on the information obtained from third parties
and an on-going evaluation of the Company's own systems. The Company anticipates
having a contingency plan in place by mid-1999,  which will include  development
of  backup  procedures,  identification  of  alternate  suppliers  and  possible
increases in supplies  inventory levels. The Company has not identified its most
reasonably  likely  worst  case  scenario  with  respect to  possible  losses in
connection with Year 2000 related problems. The Company plans on completing this
analysis in mid-1999.

     The  information  above  contains  forward-looking   statements  including,
without  limitation,  statements  relating to the Company's  plans,  strategies,
objectives,  expectations,  intentions,  and  adequate  resources  that are made
pursuant to the "safe harbor"  provisions of the Private  Securities  Litigation
Reform Act of 1995. Readers are cautioned that forward-looking  statements about
the Year 2000 should be read in conjunction with the Company's disclosures under
the heading: "Caution on forward-looking statements".


CAUTION ON FORWARD-LOOKING STATEMENTS

     The Company's business is subject to significant  risks,  including but not
limited  to, the risks  inherent in its  research  and  development  activities,
including the successful continuation of the Company's strategic collaborations,
the  successful  completion  of clinical  trials,  the  lengthy,  expensive  and
uncertain process of seeking regulatory approvals, uncertainties associated both
with the  potential  infringement  of patents  and other  intellectual  property
rights of third  parties,  and with  obtaining and enforcing its own patents and
patent rights, uncertainties regarding government reforms and of product pricing
and reimbursement  levels,  technological change and competition,  manufacturing
uncertainties  and  dependence on third parties.  Even if the Company's  product
candidates appear promising at an early stage of development, they may not reach
the market for numerous reasons. Such reasons include the possibilities that the
product will be  ineffective  or unsafe  during  clinical  trials,  will fail to
receive necessary  regulatory  approvals,  will be difficult to manufacture on a
large  scale,  will  be  uneconomical  to  market  or  will  be  precluded  from
commercialization by proprietary rights of third parties.

     Neurocrine  will require  additional  funding for the  continuation  of its
research and product development programs, for progress with preclinical testing
and clinical  trials,  for  operating  expenses,  for the pursuit of  regulatory
approvals  for its  product  candidates,  for the costs  involved  in filing and
prosecuting  patent  applications and enforcing or defending  patent claims,  if
any, the cost of product  in-licensing  and any possible  acquisitions,  and may
require  additional   funding  for  establishing   manufacturing  and  marketing
capabilities in the future. The Company may seek to access the public or private
equity markets  whenever  conditions  are  favorable.  The Company may also seek
additional funding through strategic  alliances and other financing  mechanisms,
potentially  including  off-balance  sheet financing.  There can be no assurance
that adequate funding will be available on terms  acceptable to the Company,  if
at all.  If  adequate  funds are not  available,  the Company may be required to
curtail  significantly  one or more of its research or  development  programs or
obtain funds through  arrangements with collaborative  partners or others.  This
may require the Company to relinquish  rights to certain of its  technologies or
product candidates.

     Continued profitability is not expected as the Company's operating expenses
are anticipated to rise significantly in future periods as products are advanced
through the various development and clinical stages. Neurocrine expects to incur
additional  operating  expenses  over the next  several  years as its  research,
development,  preclinical testing and clinical trial activities increase. To the
extent  that the  Company  is unable  to obtain  third  party  funding  for such
expenses,  the Company expects that increased  expenses will result in increased
losses from  operations.  There can be no assurance that the Company's  products
under  development  will be  successfully  developed  or that its  products,  if
successfully developed,  will generate revenues sufficient to enable the Company
to earn a profit.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS



The Board of Directors and Stockholders
Neurocrine Biosciences, Inc.

We have  audited  the  accompanying  consolidated  balance  sheet of  Neurocrine
Biosciences, Inc. as of December 31, 1998 and 1997, and the related consolidated
statements of operations,  stockholders'  equity, and cash flows for each of the
three years in the period ended December 31, 1998.  These  financial  statements
are the  responsibility of the Company's  management.  Our  responsibility is to
express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all  material  respects,  the  consolidated  financial  position  of  Neurocrine
Biosciences, Inc. at December 31, 1998 and 1997, and the consolidated results of
its  operations  and its cash  flows for each of the three  years in the  period
ended  December 31, 1998,  in  conformity  with  generally  accepted  accounting
principles.

     BUSINESS  ACTIVITIES:  Neurocrine  Biosciences,  Inc. (the  "Company")  was
incorporated  in  California  on  January  17,  1992 and was  reincorporated  in
Delaware in March 1996. The Company is engaged in the discovery and  development
of  therapeutics  for the  treatment  of diseases  and  disorders of the central
nervous and immune  systems  which  includes  anxiety,  depression,  Alzheimer's
disease, obesity, stroke and multiple sclerosis.

     PRINCIPLES OF CONSOLIDATION:  The consolidated financial statements include
the accounts of  Neurocrine  Biosciences,  Inc. (the  "Company")  and its wholly
owned subsidiary,  Northwest NeuroLogic, Inc. ("NNL").  Significant intercompany
accounts and transactions have been eliminated in consolidation.

     USE OF ESTIMATES:  The  preparation  of financial  statements in conformity
with  generally  accepted  accounting  principles  requires  management  to make
estimates  and  assumptions  that affect the amounts  reported in the  financial
statements and the accompanying notes.
Actual results could differ from those estimates.

     CASH EQUIVALENTS:  The Company considers all highly liquid investments with
a maturity of three months or less when purchased, to be cash equivalents.

    SHORT-TERM INVESTMENTS  AVAILABLE-FOR-SALe:  In accordance with Statement of
Financial  Accounting  Standards ("SFAS") No. 115,  "Accounting for Certain Debt
and   Equity   Securities,"    short-term    investments   are   classified   as
available-for-sale.  Available-for-sale  securities  are  carried at fair value,
with the  unrealized  gains and  losses  reported  in a  separate  component  of
stockholders'  equity. The amortized cost of debt securities in this category is
adjusted for  amortization  of premiums and  accretion of discounts to maturity.
Such  amortization is included in investment  income.  Realized gains and losses
and   declines  in  value  judged  to  be   other-than-temporary,   if  any,  on
available-for-sale  securities  are included in investment  income.  The cost of
securities  sold is based on the specific  identification  method.  Interest and
dividends  on  securities  classified  as  available-for-sale  are  included  in
interest income.

     The Company  invests its excess cash  primarily  in  investment  grade debt
instruments,  marketable  debt  securities  of  U.S.  government  agencies,  and
high-grade commercial paper.  Management has established  guidelines relative to
diversification and maturities that maintain safety and liquidity.

     PROPERTY  AND  EQUIPMENT:  Property  and  equipment  are  carried  at cost.
Depreciation  and  amortization  are provided over the estimated useful lives of
the assets, ranging from three to ten years, using the straight-line method.

     LICENSED  TECHNOLOGY  AND PATENT  APPLICATION  COSTS:  Licensed  technology
consists of exclusive,  worldwide,  perpetual licenses to patents related to the
Company's  platform  technology which are capitalized at cost and amortized over
periods of 7 to 11 years.  These costs are regularly  reviewed to determine that
they  include  costs for patent  applications  the  Company is  pursuing.  Costs
related to applications  that are not being actively pursued are evaluated under
Accounting Principles Board Statement 17 "Intangible Assets" and are adjusted to
an  appropriate   amortization  period  which  generally  results  in  immediate
write-off.  Accumulated  amortization at December 31, 1998 and 1997 was $679,000
and $461,000, respectively.

     IMPAIRMENT  OF  LONG-LIVED  ASSETS:  The  Company  routinely  assesses  the
recoverability of long-lived assets by determining whether the carrying value of
such assets can be recovered through  undiscounted  future operating cash flows.
If  impairment  is  indicated,  the  Company  will  measure  the  amount of such
impairment by comparing the carrying  value of the asset to the present value of
the expected future cash flows associated with the use of the asset.

     INDUSTRY  SEGMENT AND  GEOGRAPHIC  INFORMATION:  The Company  operates in a
single industry  segment - the discovery and development of therapeutics for the
treatment  of diseases  and  disorders  of the central  nervous and immune.  The
Company has no foreign operations.

     RESEARCH AND DEVELOPMENT REVENUE AND EXPENSES: Revenues under collaborative
research  agreements  are  recognized  over the period  specified in the related
agreement.  Advance payments received in excess of amounts earned are classified
as deferred revenue and recognized as income in the period earned. Revenues from
government  grants are recognized  based on the performance  requirements of the
grant or as the grant expenditures are incurred.  Research and development costs
are  expensed  as  incurred.   Such  costs  include  proprietary   research  and
development  activities  and expenses  associated  with  collaborative  research
agreements.   Research  and  development   expenses  relating  to  collaborative
agreements and grants were  approximately  $12.0 million,  $9.4 million and $8.3
million during 1998, 1997 and 1996, respectively.

     STOCK-BASED  COMPENSATION:  The Company accounts for stock option grants to
employees  in  accordance  with  Accounting  Principles  Board  Opinion  No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related  Interpretations
because the Company believes the alternative fair value accounting  provided for
under SFAS No. 123, "Accounting for Stock-Based  Compensation," requires the use
of option  valuation  models that were not developed for use in valuing employee
stock options. Deferred compensation is recorded only in the event that the fair
market value of the stock on the date of the option  grant  exceeds the exercise
price of the options.  Such deferred  compensation is amortized over the vesting
period of the options.  Compensation  expense  recognized during the years ended
December  31,  1998,   1997  and  1996  was  $194,000,   $129,000  and  $79,000,
respectively.

     EARNINGS PER SHARE:  Basic and diluted  earnings per share is calculated in
accordance with FASB Statement No. 128,  "Earnings per Share".  All earnings per
share  amounts  for all  periods  have been  presented,  and where  appropriate,
were restated to conform to the requirements of Statement No. 128.

    COMPREHENSIVE INCOME:  Comprehensive income is calculated in accordance with
FASB  Statement No. 130,  "Comprehensive  Income".  The  Statement  requires the
disclosure of all components of comprehensive  income,  including net income and
changes  in  equity  during a period  from  transactions  and other  events  and
circumstances   generated   from   non-owner   sources.   The  Company's   other
comprehensive income consisted of gains and losses on short-term investments and
is reported in the consolidated statement of stockholders' equity.

     RECLASSIFICATIONS:  Certain  reclassifications have been made to prior year
amounts to conform to the presentation for the year ended December 31, 1998.

    IMPACT OF  RECENTLY  ISSUED  ACCOUNTING  STANDARDS:  In June 1998,  the FASB
issued  Statement No. 133,  "Accounting  for Derivative  Instruments and Hedging
Activities". The Company expects to adopt the new Statement effective January 1,
2000. The Statement will require the Company to recognize all derivatives on the
balance sheet at fair value.  The Company does not anticipate  that the adoption
of the Statement will have a significant  effect on its results of operations or
financial position.


2.  ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT AND LICENSES

     NORTHWEST NEUROLOGIC, INC: In May 1998, the Company acquired the assets and
liabilities of Northwest NeuroLogic,  Inc. ("NNL"), a neurodegenerative research
and  development  company,  in exchange for 392,608  shares of Company's  Common
Stock and 105,414 of stock options valued at $4.2 million. The operations of NNL
are  included  in the  consolidated  statement  of  operations  from the date of
acquisition.

     The  acquisition  was  accounted for as a purchase  and,  accordingly,  the
purchase  price has been  allocated to the assets  acquired and the  liabilities
assumed based on the estimated fair market value at the date of the acquisition.
The amount  allocated  to  in-process  research and  development  was charged to
expense because the technology has not reached technological feasibility and has
no future  alternative  uses.  The purchase  price was  allocated as follows (in
thousands):

     Current assets ..............................  $   180
     Furniture and equipment .....................       49
     Liabilities assumed .........................     (207)
     In-process research and development .........    4,200
                                                    ------- 
     Total purchase price ........................  $ 4,222
                                                    =======

     The acquired in-process research and development  consisted of Melanocortin
("MCR"), a brain receptor technology relating obesity and  Excitatory Amino Acid
Transporters  ("EAATs"),  a technology relating to neurodegeneration and stroke.
Both in-process research and development are in early developmental stages.

    The nature and efforts required to develop the acquired  in-process research
and development  into  commercially  viable products  include  completion of the
development  stages of a  compound,  pre-clinical  development,  clinical  trial
testing,  FDA  approval  and  commercialization.   Due  to  the  nature  of  the
pharmaceutical  development process, the Company anticipates substantial further
research and clinical  expenditures to develop the products.  There is, however,
no certainty that either of these programs will result in viable products.

     The following  are the pro forma  unaudited  results of operations  for the
years ended December 31, 1998 and 1997, had the purchase of NNL been consummated
as of January 1, of the respective years:

                                               1998                1997
                                           ------------------------------------
                                          (in thousands, except per share data)
               
               Revenues ..................  $ 16,325             $ 26,783
               Net income (loss) .........   (20,013)                 975
               Earnings (loss) per share:
               Basic .....................  $  (1.09)              $ 0.06
               Diluted ...................     (1.09)                0.05

     This pro forma  information  is not  necessarily  indicative  of the actual
results that would have been  achieved had NNL been acquired on January 1, 1997,
nor is it necessarily indicative of future results.

     OTHER:  During  1998,  the  Company  purchased  licenses  for  technologies
relating to insomnia in the amount of $440,000 and brain cancer in the amount of
$270,000.  These  projects  are in the  early  stages of  development,  have not
reached   technological   feasibility  and  have  no  known   alternative  uses.
Consequently, the costs of these licenses were expensed.

6.  LONG-TERM DEBT

     During 1997, the Company partially  financed the purchase of land under a 5
year note payable for approximately $747,000, which bears interest at a floating
rate of prime plus one quarter percent (8.00% at December 31, 1998). The note is
repayable in equal monthly installments beginning February 1998.

     At December 31, 1998, the repayment  schedule for the note was $149,000 for
each year 1999 through 2002 and $13,000 in the year 2003.


7.  COMMITMENTS AND CONTINGENCIES

     CAPITAL LEASE OBLIGATIONS: The Company has financed certain equipment under
capital  lease  obligations  which expire on various dates through the year 2002
and bear interest at rates  between 7.6% and 11.6%.  The lease  commitments  are
repayable in monthly installments.

     OPERATING  Leases:  In May 1997, the Company purchased two adjacent parcels
of land in San Diego for $5.0  million.  In August  1997,  the Company  sold one
parcel to Science Park Center LLC, a California  limited  liability company (the
"LLC"),  of which the Company owns a minority  interest,  in exchange for a note
receivable  in the amount of $3.5 million plus interest of 8.25%.  However,  for
accounting purposes,  this transaction does not qualify as a sale under SFAS No.
98 and therefore,  the entire amount of the note receivable is included in land.
The amount  included in land at December  31, 1998 and 1997 was $3.8 million and
$3.5 million, respectively.

     During 1998, the LLC constructed an expanded  laboratory and office complex
which was leased by the  Company  under a 15 year  operating  lease,  commencing
September  1998. The Company has the option to purchase the facility at any time
during the term of the lease at a predetermined  price.  The lease contains a 4%
per year  escalation  in base rent fees,  effective  with each  anniversary.  In
November 1998, the Company  subleased a portion of this facility to an unrelated
third party for a term of 20 months.  The Company will hold the second parcel of
land until such a time as additional facilities are required.

     In November 1998,  the lease  obligation  relating to the Company's  former
operating facility was amended to reduce the amount of square footage leased and
to  shorten  the lease term to  conclude  in June 2000.  The  Company  currently
subleases  this space to an  unrelated  third party and is obligated to continue
this arrangement through June 2000.

     Repayment  schedules for the capital lease  obligations and operating lease
commitments at December 31, 1998 are as follows (in thousands):

     The weighted  average fair values of the options  granted during 1998, 1997
and 1996 were $5.59, $5.01 and $5.79, respectively.

     Pro forma  information  regarding net income (loss) is required by SFAS No.
123, and has been  determined  as if the Company had  accounted for its employee
stock options under the fair value method of that Statement.  The fair value for
these  options was estimated at the date of grant using a  Black-Scholes  option
pricing model using the following  weighted-average  assumptions  for 1998, 1997
and 1996,  respectively:  risk-free  interest  rates of 5.5%,  5.8% and 6.1%;  a
dividend  yield of 0.0% (for all  years),  volatility  factors  of the  expected
market price of the  Company's  common stock of .88, .43 and .41; and a weighted
average expected life of the option of 5 years (for all years presented).

     For  purposes of pro forma  disclosures,  the  estimated  fair value of the
options granted is amortized to expense over the options'  vesting  period.  The
pro forma effect on net income loss for 1998 and net income in 1997 and 1996, is
not likely to be  representative  of the effects on  reported  income or loss in
future years because  these  amounts  reflect less than full vesting for options
granted during these periods.  The Company's pro forma information for the years
ended  December 31, 1998,  1997 and 1996 follows (in  thousands,  except for per
share data):

     EMPLOYEE STOCK  PURCHASE  PLAN: The Company has reserved  125,000 shares of
Common Stock for  issuance  under the 1996  Employee  Stock  Purchase  Plan (the
"Purchase  Plan").  The  Purchase  Plan permits  eligible  employees to purchase
Common Stock through payroll  deductions at a purchase price equal to 85% of the
lesser of the fair market  value per share of Common  Stock on the start date of
an  offering  period or on the date on which the shares are  purchased.  Through
December 31, 1998, 51,082 shares had been issued pursuant to the Purchase Plan.

     WARRANTS:  The Company has outstanding  warrants to purchase 388,185 shares
of Common Stock at exercise  prices of $5.00 and $10.50 per share.  The warrants
generally  expire between 1998 and 2007. At December 31, 1998,  all  outstanding
warrants were exercisable.

     The  following  shares of Common Stock are reserved for future  issuance at
December 31, 1998:

outstanding grants and 672,478 remain available for future grant.


9.   COLLABORATIVE RESEARCH AND DEVELOPMENT AGREEMENTS

     JANSSEN:  In  January  1995,  the  Company  entered  into  a  research  and
development  agreement  (the  "Janssen  Agreement")  with  Janssen,  under which
Janssen paid the Company $2.0 million in up-front  license fees and $9.7 million
in sponsored  research  payments during the three-year term of the collaborative
research  portion of the  agreement.  The research  portion of the agreement was
completed in 1997.

     Under the Janssen Agreement, the Company is entitled to receive up to $10.0
million in milestone  payments for the  indications  of anxiety,  depression and
substance  abuse,  and up to $9.0 million in additional  milestone  payments for
other indications. Milestone payments of $3.5 million have been received through
December  31,  1998.  The  Company has granted  Janssen an  exclusive  worldwide
license  to  manufacture  and  market  products   developed  under  the  Janssen
Agreement.  The Company is entitled to receive  royalties on  worldwide  product
sales and has certain  rights to  co-promote  such  products  in North  America.
Janssen is  responsible  for  funding all  clinical  development  and  marketing
activities,  including  reimbursement to Neurocrine for its promotional efforts,
if any.

     The  collaborative  research  portion of the  agreement  was  completed  as
scheduled  in  1997  with  the  selection  of  a  clinical   candidate  and  the
commencement of clinical trials in Europe.  The Company will continue to receive
milestone  payments  and  royalties  upon  the  successful  continuation  of the
development portion of the agreement.

     Janssen has the right to terminate  the Agreement  upon six months  notice.
However,  in the event of  termination,  other than  termination  by Janssen for
cause  or as a  result  of  the  acquisition  of  Neurocrine,  all  product  and
technology rights become the exclusive property of Neurocrine.

     NOVARTIS:  In January  1996,  the Company  entered into an  agreement  with
Novartis under which Novartis paid the Company $5.0 million in up-front  license
fees and is  obligated to provide  Neurocrine  with $7.0 million in research and
development  funding during the first two years of the agreement and up to $15.5
million in further research and development funding  thereafter.  As of December
31, 1998,  the Company has  received  $15.2  million in  sponsored  research and
development  payments.  In  addition,  the  Company is also  entitled to receive
milestone  payments for certain  development  and regulatory  achievements.  The
Company has received  $9.1 million of milestone  payments  through  December 31,
1998 of which $2.3 million was received in 1998.

     In return,  Novartis received manufacturing and marketing rights outside of
North  America  and will  receive  a  percentage  of  profits  on sales in North
America.  The Company will receive royalties for all sales outside North America
and a percentage of profits on sales in North America,  which the Company may at
its option convert to a right to receive royalties on product sales.  Neurocrine
is obligated to repay a portion of the development costs for potential  products
developed  in such  collaboration  unless the  Company  elects to convert to the
right to receive  royalty  payments.  Novartis  has the right to  terminate  the
agreement upon six months notice.

     ELI LILLY:  In October 1996, the Company entered into an agreement with Eli
Lilly and Company  under which the Company  expects to receive  $22.0 million in
research  payments of which $14.5  million have been received as of December 31,
1998. The Company is also entitled to milestone payments for certain development
and  regulatory  accomplishments.  The  Company  will have the option to receive
co-promotion  rights and share profits from commercial sales of select products,
which  result from the  collaboration  in the U.S. or receive  royalties on U.S.
product sales. The Company will receive  royalties on product sales for the rest
of the world.


10.  RELATED PARTY TRANSACTIONS

     Neuroscience  Pharma, Inc: In March 1996, the Company along with a group of
Canadian   institutional   investors  (the  "Canadian  Investors")   established
Neuroscience  Pharma Inc.  ("NPI").  The Company's  contribution  was to license
certain  technology and Canadian marketing rights to NPI. The Canadian Investors
contributed  approximately  $9.5 million in cash in exchange for Preferred Stock
of NPI, which could be converted into 1,279,758  shares of the Company's  Common
Stock at the option of the investors.  Upon conversion of the Preferred  Shares,
ownership  of  the  shares  transfer  to  the  Company  and  is  redeemable  for
approximately $9.5 million in cash at the option of the Company.

     NPI has committed to use these funds for research and clinical  development
of certain of the  Company's  programs in  exchange  for  royalties  on sales of
products  developed,  as well as, exclusive  Canadian  marketing rights for such
products in certain  situations.  The Company  has the right to  terminate  this
agreement upon the conversion of the Preferred  Shares. In connection with their
investment in NPI, the Canadian Investors also received warrants exercisable for
383,875 shares of the Company's  Common Stock at an exercise price of $10.50 per
share and are also  eligible to receive  additional  warrants in the future upon
attainment of certain additional funding.

     During  December 1997 and October 1998,  the Canadian  Investors  converted
their  Preferred  Shares to Neurocrine  Common Stock.  As a result,  the Company
recorded an  investment  in NPI equal to the market value of Common Stock issued
in exchange for the Preferred Shares and has recognized its proportionate  share
of NPI net losses in accordance with the equity method of accounting.

     The Preferred Shares are redeemable for approximately  $9.5 million in cash
at the Company's option.  The redemption  feature of the Preferred Shares limits
their  value to the  balance  of cash and cash  equivalents  maintained  by NPI.
Consequently,  the  Company  reduced  the  value of its NPI  investment  by $3.8
million  during 1998.  Equity in NPI losses was $3.4 million and $1.1 million in
1998 and 1997, respectively.  The balance of the Company's investment in NPI was
$1.4 million and $3.3 million at December 31, 1998 and 1997, respectively.

     During 1996, the Company entered into a sponsored  research  agreement with
NPI.  The terms of the  agreement  called  for NPI to fund  additional  research
efforts on technologies licensed to NPI by the Company. During 1998, the Company
recognized  $3.6  million in revenues  associated  with costs of research on the
Neurogenomics and DHEA programs.


11.   INCOME TAXES

     At December 31, 1998, the Company had federal and California income tax net
operating loss  carryforwards  of  approximately  $9.3 million and $8.3 million,
respectively.  The federal and California tax loss  carryforwards  will begin to
expire in 2009 and 2003,  respectively,  unless previously utilized. The Company
also  has  federal  and  California   research  tax  credit   carryforwards   of
approximately  $1.6  million  and  $271,000,  respectively,  which will begin to
expire in 2007 and 2012,  respectively,  unless previously utilized. The Company
has  federal  Alternative  Minimum  Tax credit  carryforwards  of  approximately
$257,000, which will carryforward indefinitely.

     Pursuant to Internal  Revenue Code Sections 382 and 383,  annual use of the
Company's net operating loss and credit  carryforwards may be limited because of
cumulative  changes in ownership of more than 50% which occurred during 1992 and
1993.  However,  the Company  does not believe  such change will have a material
impact upon the utilization of these carryforwards.

     Significant  components of the Company's deferred tax assets as of December
31, 1998 and 1997 are shown  below.  A valuation  allowance  of  $6,470,000  and
$3,474,000 at December 31, 1998 and 1997, respectively,  have been recognized to
offset the net deferred tax assets as  realization  of such assets is uncertain.
Amounts are shown in thousands as of December 31, of the respective years:

13.       SUBSEQUENT EVENT

     On March 2, 1999, the Company entered into a  collaboration  agreement with
Wyeth-Ayerst Laboratories, the pharmaceutical division of American Home Products
Corporation  on the research,  development  and  commercialization  of compounds
which modulate excitatory amino acid transporters ("EAATs") for the treatment of
neurodegenerative  and  psychiatric  diseases.  The agreement,  valued up to $78
million,  provided that marketable  products for these disorders result from the
collaboration,   includes  sharing  proprietary  technologies  between  the  two
companies;  funding  for  research  and  milestone  achievements  and  potential
royalties on world-wide sales of products resulting from the collaboration.  The
Company  expects to receive  three to five years of  funding  for  research  and
development activities,  in addition to access to Wyeth's chemical libraries for
screening within the collaborative field.
