                          NEUROCRINE BIOSCIENCES, INC.
            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (unaudited)

1.  BASIS OF PRESENTATION

    The  condensed   consolidated   financial  statements  included  herein  are
unaudited.  These  financial  statements  include  the  accounts  of  Neurocrine
Biosciences,   Inc.  ("Neurocrine"  or  the  "Company")  and  its  wholly  owned
subsidiary,  Northwest  NeuroLogic,  Inc. ("NNL"). All significant  intercompany
transactions  have been  eliminated in  consolidation.  The  Company's  minority
ownership interest in Neuroscience  Pharma,  Inc. ("NPI") has been accounted for
under the equity method. Certain  reclassifications have been made to prior year
amounts to  conform  to the  presentation  for the three and nine  months  ended
September 30, 1999.

    The  condensed  consolidated  financial  statements  have been  prepared  in
accordance with generally accepted  accounting  principles for interim financial
information and with the instructions of the Securities and Exchange  Commission
on Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly,  they do not include
all of the information and footnotes required by generally  accepted  accounting
principles  for complete  financial  statements.  In the opinion of  management,
these  financial  statements  include  all  adjustments  (consisting  of  normal
recurring  adjustments)  necessary  for a fair  presentation  of  the  financial
position, results of operations, and cash flows for the periods presented.

    The results of operations  for the interim  periods shown in this report are
not necessarily  indicative of results expected for the full year. The financial
statements should be read in conjunction with the audited  financial  statements
and notes for the year ended December 31, 1998, included in the Company's Annual
Report on Form 10-K filed with the Securities and Exchange Commission.

2.  NET INCOME PER SHARE

     In accordance with Financial  Accounting Standards Board Statement No. 128,
"Earnings  Per Share",  basic  earnings per share is  calculated by dividing net
income by the  weighted  average  number of common  shares  outstanding  for the
period. Diluted earnings per share reflects the potential dilution of securities
that could share in the  earnings of the Company  such as common stock which may
be issuable  upon exercise of  outstanding  common stock  options,  warrants and
preferred stock.  These shares are excluded when their effects are antidilutive.
For the three and nine months  ended  September  30, 1999 and 1998,  potentially
dilutive   securities  were  excluded  from  the  diluted   earnings  per  share
calculation.

3.  COMPREHENSIVE INCOME

     Financial  Accounting  Standards  Board  Statement No. 130,  "Comprehensive
Income",  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.   Other
comprehensive  income  consisted of gains (losses) on short-term  investments of
$8,000 and  ($142,000)  for the three and nine months ended  September 30, 1999;
and $16,000 and $21,000 for the same periods in 1998, respectively.

Item 2:  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 the Company  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  payments,  pre-clinical  testing and  clinical  trials of  potential
products,  the period of time the Company's existing capital resources will meet
its funding requirements,  and financial results and operations.  Actual results
could  differ  materially  from  those  anticipated  in  these   forward-looking
statements as a result of various  factors,  including those set forth below and
those  outlined in the Company's  1998 Annual Report on Form 10-K filed with the
Securities and Exchange Commission.


     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 in the  foreseeable  future.  The
Company has funded its operations primarily through public offering and payments
under research and development agreements. The Company is developing a number of
products with corporate  collaborators and will rely on those  collaborators and
new  collaborators to meet funding  requirements.  Revenues are expected to come
from the Company's strategic  alliances.  The Company expects to generate future
net losses in  anticipation  of significant  increases in operating  expenses as
products are advanced through the various stages of clinical development.  As of
September  30,  1999,  Neurocrine  has  incurred a  cumulative  deficit of $38.0
million  and  expects  to incur  operating  losses in the  future,  which may be
greater than losses in prior years.


     RESULTS OF OPERATIONS

                 THREE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998
                 ----------------------------------------------

    Revenues for the third  quarter of 1999 were $5.2  million  compared to $5.1
million for the respective  period in 1998.  The increase in revenues  primarily
resulted   from  the  1999   collaborations   with   Wyeth-Ayerst   and  Janssen
Pharmaceutica,  a subsidiary of Johnson & Johnson.  The  Wyeth-Ayerst  agreement
included a number of milestone  payments,  one of which was achieved  during the
third  quarter  earning a $750,000  payment in addition to  quarterly  sponsored
research  payments of  $750,000.  The Janssen  agreement  contributed  sponsored
research and  development  revenues of $1.7 million to third  quarter  revenues.
Revenues in 1998 included $2.1 million in sponsored  development  from NPI and a
$750,000 milestone payment from Novartis.

    Research and  development  expenses  increased to $8.3 million for the third
quarter  of 1999  compared  to $6.4  million  for the same  period in 1998.  The
increase  reflects higher costs associated with increased  scientific  personnel
and related  expenditures as the Company  advances its drug  candidates  through
clinical  testing.  Currently,  the  Company  has  five  compounds  in  clinical
development.

    General and  administrative  expenses  increased to $1.9 million  during the
third quarter of 1999 compared to $1.8 million for the same period in 1998.  The
increase resulted primarily from additional administrative  personnel,  business
development and professional  service expenses to support the expanded  clinical
development efforts.



    Interest  income  decreased  to  $623,000  during the third  quarter of 1999
compared  to $1.2  million  for the same  period  last year.  The  decrease  was
primarily  due to a decline in  investment  balances.  The  Company  anticipates
further decline in interest income as cash reserves are used to fund progressive
clinical trials.

    Net loss for the third  quarter of 1999 was $4.4  million or $0.23 per share
compared  to $4.0  million  or $0.22  per  share  for the same  period  in 1998.
Increased revenues of $177,000 were used to finance the $2.0 million increase in
operating  expenses primarily related to clinical  development  costs.  Interest
income  declined  by  $551,000  and  non-cash  charges  relating  to NPI  equity
transactions decreased by $2.0 million.

    To  date,  the  Company's  revenues  have  come  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  quarterly  revenues  and  earnings.  Accordingly,  results  and
earnings of one period are not predictive of future periods.


                  NINE MONTHS ENDED SEPTEMBER 30, 1999 AND 1998
                  ---------------------------------------------

    Revenues for the nine months  ended  September  30, 1999 were $12.6  million
compared to $11.5 million for the same period in 1998.  The increase in revenues
primarily  resulted from the 1999  collaborations  with Wyeth-Ayerst and Janssen
Pharmaceutica,  a subsidiary of Johnson & Johnson.  The  Wyeth-Ayerst  agreement
included a number of milestone  payments,  two of which were achieved  earning a
$1.5 million  payment in addition to quarterly  sponsored  research  payments of
$750,000.  The Janssen agreement  contributed sponsored research and development
revenues  of $1.7  million to third  quarter  1999  revenues.  Revenues  in 1998
included $2.1 million in sponsored development from NPI and a $750,000 milestone
payment from Novartis.

         Research and  development  expenses  increased to $21.9 million for the
nine months  ended  September  30, 1999  compared to $15.5  million for the same
period in 1998. The increase  reflects  higher costs  associated  with increased
scientific  personnel  and  development  costs as the Company  advances its drug
candidates  through  the  clinical  testing.  The  Company  currently  has  five
compounds in clinical development.

    General and  administrative  expenses  increased to $5.6 million  during the
nine  months  ended  September  30, 1999  compared to $4.7  million for the same
period last year.  The increase is  attributable  to  additional  administrative
personnel, business development and professional service expenses to support the
expanded clinical development efforts.

    During  1998,  the  Company  wrote-off  acquired   in-process  research  and
development  fees of $4.9  million.  Of that total,  $4.2 million were  non-cash
charges  relating to the  acquisition of NNL. The balance is attributable to the
in-licensing  of compounds  for insomnia and  glioblastoma.  Both  compounds are
currently in clinical development programs.

    Interest  income  decreased  to $2.2  million  during the nine months  ended
September 30, 1999  compared to $3.3 million for the same period last year.  The
decline in interest income resulted from lower investment balances.  The Company
anticipates further decline in interest income as cash reserves are used to fund
progressive clinical trials.

    Net loss for the nine months ended  September  30, 1999 was $13.1 million or
$0.69 per share compared to $13.2 million or $0.74 per share for the same period
in 1998.  During 1999,  increased  revenues of $1.1 million were used to finance
the $7.3 million increase in operating expenses related to clinical  development
and  administration.  Write-off of acquired  in-process research and development
costs and equity  transactions  related to NPI  decreased  by $7.5  million.  In
addition, the Company experienced a decline of $1.1 million in interest income.

    To  date,  the  Company's  revenues  have  come  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

     At September 30, 1999, the Company's cash, cash equivalents, and short-term
investments  totaled $48.5  million  compared with $62.7 million at December 31,
1998.  The decline in cash balances  during 1999  reflects the increased  losses
associated with the progressive  clinical  development programs and the addition
of scientific personnel.

     Net cash used in operating  activities during the first nine months of 1999
was $12.4 million  compared with $8.0 million for the same period last year. Net
cash used during  1999 and 1998  reflects  the  payment of clinical  development
expenses  and other  accrued  liabilities.  The  Company  anticipates  continued
funding of clinical trials to use cash in future periods.

     Net cash  provided by  investing  activities  during 1999 was $7.9  million
compared  with $8.7  million  during  1998.  The  increase in cash  provided was
primarily  the result of timing  differences  in the  investment  purchases  and
sales/maturities  and the  fluctuations  in the Company's  portfolio mix between
cash  equivalents  and  short-term  investment  holdings,  net of capital  asset
purchases of $2.0 and $3.1 million during 1999 and 1998, respectively.

     Net cash provided by financing activities during 1999 was $421,000 compared
to $2.0 million in 1998.  Cash provided by proceeds from Common Stock  issuances
and capital lease financing, net of payments on long-term obligations,  resulted
in net cash provided during 1999 and 1998.

     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 2001.  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.  Failure  of a  corporate  collaborator  to meet its
contractual  obligations  could have a material  adverse effect on the Company's
financial position and results of operations.


     INTEREST RATE RISK

     The  Company is exposed to changes in  interest  rates  primarily  from its
long-term debt. 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.

      Interest  risk exposure on long-term  debt relates to the  Company's  note
payable which bears a floating  interest rate of prime plus one quarter  percent
(8.50% at September 30, 1999 and 8.00% at December 31,  1998).  At September 30,
1999 and  December  31,  1998,  the note  balance  was  $498,000  and  $610,000,
respectively. This note is payable in equal monthly installments through January
2003.


     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.



     In the normal course of business  over the past two years,  the Company has
made  incremental  modifications  and improvements to all of its operational and
financial software. An integral part of this process has been to ensure that all
newly purchased  software and hardware are Year 2000 compliant.  The Company has
completed an evaluation of all of the existing software and hardware used in its
internal systems and operations and is now Year 2000 compliant.  The Company has
also evaluated and replaced or remediated  various  hardware  components used in
its  laboratory  operations  and now believes it is Year 2000  compliant in this
area as well. In general,  the Company  management is satisfied with its efforts
to be Year2000  prepared,  however,  it will  continue  to monitor and  reassess
systems through the end of the year.

     Because third party  failures  could have a material  adverse impact on the
Company's  ability  to conduct  business,  the  Company  has  requested  written
assurances  from all material  customers  and vendors that their  systems are or
will be Year 2000 compliant.  The Company has received such assurances from many
of  its  domestic  material  customers  and  vendors  as  well  as  many  of its
international  customers and vendors;  however, this is an on-going process. The
business interruption of any of the Company's significant  customers,  materials
suppliers and service  providers  resulting  from their Year 2000 issues,  could
have a  material  adverse  impact  on the  Company's  revenues  and  results  of
operations.

     Based on information  obtained from third parties and on-going  evaluations
of the Company's own systems,  management  believes it has  identified  the most
reasonably  likely  worst  case  scenario  with  respect to  possible  losses in
connection with Year 2000 related problems.  Based on this scenario, the Company
has developed  contingency  plans for  restoration  of financial and  scientific
data,  replacement of material  suppliers and service providers and the building
of safety  stocks  of  critical  materials  in the event  that  current  vendors
experience Year 2000 compliance issues.

     The   incremental   cost  to  the  Company  of  Year  2000  compliance  was
approximately $175,000. The expensed costs do not include internal costs, as the
Company does not separately  track the internal  costs of Year 2000  compliance.
Such internal costs are  principally the related payroll costs for the Company's
information technology group.

     There are many factors  outside the Company's  control that could cause the
Year 2000 problem to seriously disrupt its operations.  However, the Company has
identified certain risks and has developed  contingency plans in order to reduce
its exposure in these areas. The scope of the Company's  efforts  regarding each
risk is limited to the  Company's  key products,  key  compounds,  subsidiaries,
critical suppliers, and major customers. The most critical of these risks are: a
disruption in the supply of product with particular  emphasis on failures of raw
material suppliers,  commercial partners,  and external  distribution  channels;
internal  infrastructure  failures such as utilities,  communications,  internal
information technology services and integrated information technology systems.

     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, for 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.

     The Company believes that its existing  capital  resources will be adequate
to satisfy its current and planned operations through the year 2000.  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.
