              NOTES TO 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. and  Northwest  NeuroLogic,  Inc., a wholly owned  subsidiary
since its acquisition on May 28, 1998. All significant intercompany transactions
were eliminated in consolidation.

    The  condensed  consolidated  financial  statements  have been  prepared  in
accordance with generally accepted  accounting  principles for interim financial
information.  Accordingly,  they  do not  include  all of  the  information  and
footnotes  required by generally  accepted  accounting  principles  for complete
financial   statements.   The  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,  1997,  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" ("SFAS  128"),  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. As required by SFAS 128, the Company has restated the earnings per
share presentations for the periods ended June 30, 1997.

3.  COMPREHENSIVE INCOME

    In June 1997, the Financial  Accounting  Standards Board issued Statement of
Financial  Accounting  Standard No. 130,  "Comprehensive  Income"  ("SFAS 130"),
which  applies to  financial  statements  issued  for  periods  beginning  after
December  15,  1997.  SFAS 130  requires the  disclosure  of all  components  of
comprehensive  income,  including  net  income and other  comprehensive  income.
Comprehensive   income   includes   changes  in  equity  during  a  period  from
transactions  and  other  events  and  circumstances  generated  from  non-owner
sources.   For  the  three  and  six  months  ended  June  30,  1998  and  1997,
comprehensive income is calculated as follows:

4.    ACCOUNTING FOR PENSIONS AND HEDGING ACTIVITIES

    In February 1998, the Financial  Accounting Standards Board issued Statement
of Financial Accounting Standard No. 132, "Employee's  Disclosures about Pension
and Other  Post-retirement  Benefits",  which is effective for periods beginning
after December 15, 1997 ("SFAS 132"). SFAS 132 revises disclosures about pension
and other  post-retirement  benefit plans.  The Company  believes this statement
will have no material impact on its financial position or results of operations.

    In June 1998, the Financial  Accounting  Standards Board issued Statement of
Financial   Accounting   Standard  No.  No.  133,   "Accounting  for  Derivative
Instruments and Hedging Activities",  which is effective for all fiscal quarters
of fiscal years beginning after June 15, 1999 ("SFAS 133"). SFAS 133 establishes
accounting and reporting standards for derivative instruments, including certain
derivative instruments embedded in other contracts,  and for hedging activities.
SFAS No. 133 requires an entity to recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. The Company is currently  evaluating the impact SFAS No. 133 will
have on its financial statements, if any.



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 Neurocrine  Biosciences,  Inc. ("Neurocrine" or the
"Company")   contains   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  1997 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's  revenues  are  expected  to come from its  strategic  alliances.  The
Company  expects to generate  further net losses as its  operating  expenses are
anticipated  to rise  significantly  in future  periods as products are advanced
through the various  stages of clinical  development.  Neurocrine has incurred a
cumulative  deficit  of  approximately  $14.1  million  as of June 30,  1998 and
expects to incur operating losses in the future,  which are potentially  greater
than losses in prior years.

RESULTS OF OPERATIONS

       Three months ended June 30, 1998 compared with three months ended
                                  June 30, 1997

    Revenues for the second  quarter of 1998 were $2.3 million  compared to $4.8
million  for the  comparable  period in 1997.  The  decline  of $2.5  million in
revenues  resulted from the  completion of sponsored  research under the Janssen
collaboration and milestone  payments received under the Novartis  collaboration
during 1997.

    The  research  completed  under  the  Janssen  collaboration  resulted  in a
clinical compound (R121919). Janssen is currently conducting Phase I trials with
R121919  for  anxiety/depression  and is expected to progress to Phase II trials
near  the end of the  third  quarter  of  1998.  Phase II  trials  for  multiple
sclerosis under the Novartis collaboration is currently in progress.

    Research and development  expenses  increased to $4.9 million for the second
quarter of 1998  compared  to $4.4  million  for the same  period in 1997.  This
increase  reflects higher costs associated with increased  scientific  personnel
and related  support  expenditures  as the Company  broadens  its  research  and
clinical  development  pipeline.  General and  administrative  expenses remained
constant at $1.3 million  during the second quarter of 1998 compared to the same
period in 1997.

    Special  charges for the second  quarter of 1998  consisted  of $4.2 million
related to the acquisition of Northwest  Neurologic,  Inc. ("NNL"), $1.3 million
related  to  the  in-licensing  of  two  chemical  compounds  for  insomnia  and
glioblastoma, and additional investment in the Company's Canadian affiliate.

    Interest income  increased to $1.0 million during the second quarter of 1998
compared to $910,000  for the same period last year.  This  increase  was due to
higher effective  interest yields on the Company's  investment  portfolio during
the second quarter of 1998.

    Net  losses for the  second  quarter of 1998 were $8.0  million or $0.45 per
share  ($0.14 per share  excluding  special  charges)  compared to net income of
$103,000  or  approximately  $0.01 per share  for the same  period in 1997.  The
decrease  in net  earnings  and  earnings  per  share  resulted  primarily  from
non-recurring  collaborative  revenues  of $2.5  million  reported  in 1997  and
special charges of $5.5 million reported during the second quarter of 1998.

    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.

         Six months ended June 30, 1998 compared with six months ended
                                 June 30, 1997

    Revenues for the first half 1998 were $6.4 million compared to $13.7 million
for the  comparable  period in 1997.  The decline in  revenues  of $7.3  million
resulted from the completion of sponsored research under Janssen  collaboration,
milestone payments received under the Novartis  collaboration and a $5.0 million
research support payment received under the Eli Lilly collaboration during 1997.

    The  research  completed  under  the  Janssen  collaboration  resulted  in a
clinical compound (R121919). Janssen is currently conducting Phase I trials with
R121919  for  anxiety/depression  and is expected to progress to Phase II trials
near  the end of the  third  quarter  of  1998.  Phase II  trials  for  multiple
sclerosis under the Novartis collaboration is in progress.

    Research and  development  expenses  increased to $9.9 million for the first
half of 1998  compared  with $9.0  million  for the same  period  in 1997.  This
increase  reflects higher costs associated with increased  scientific  personnel
and related  support  expenditures  as the Company  broadens  its  research  and
clinical development pipeline.

    General and  administrative  expenses  increased to $2.9 million  during the
first half of 1998  compared to $2.5  million  for the same period in 1997.  The
increase resulted primarily from additional administrative  personnel,  business
development and professional  service expenses to support the expanded  research
and clinical development efforts.

    Special charges for the first half of 1998 consisted of $4.2 million related
to the acquisition of Northwest  Neurologic,  Inc. ("NNL"), $1.3 million related
to the in-licensing of two chemical compounds for insomnia and glioblastoma, and
additional investment in the Company's Canadian affiliate.
    Interest  income  increased  to $2.1  million  during the first half of 1998
compared to $1.8 million for the same period last year. This increase  primarily
resulted  from higher  effective  interest  yields on the  Company's  investment
portfolio during 1998.

    Net losses  for the first half of 1998 were $9.2  million or $0.51 per share
($0.21  per share  excluding  special  charges)  compared  to net income of $4.2
million or $0.25 per share  ($0.22  per share  assuming  dilution)  for the same
period in 1997. The decrease of $13.4 million in net earnings resulted primarily
from $7.3  million of  non-recurring  collaborative  revenues  recorded in 1997,
including a $5.0 million  research  support payment received from Eli Lilly, and
special charges of $5.5 million reported in 1998.

    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 June 30, 1998,  the Company's  cash,  cash  equivalents,  and  short-term
investments   totaled  $65.2  million.   Cash  held  by  the  Company   excludes
approximately  $5.9 million  held by NPI,  which is available to fund certain of
the Company's research and development activities.

    Cash used in operating  activities  during 1998 was $7.8 million compared to
net cash  provided of $2.3 million for the same period in 1997.  The increase in
cash used in operating  activities  during 1998 was  primarily the result of the
recognition  of  deferred  revenues,  decreased  revenues  under  the  Company's
collaborations and payment of current liabilities.

    Cash provided by investing  activities during 1998 was $3.1 million compared
to net cash used of $6.5 million during the same period in 1997. The increase in
cash  provided was  primarily  the result of timing  differences  in  investment
purchases and  sales/maturities  and fluctuations in the Company's portfolio mix
between cash equivalent and short-term investment holdings.

    Cash used in financing  activities  during 1998 was $436,000 compared to net
cash  provided of $81,000 for the same period in 1997.  The increase in net cash
used was primarily due to principal payments on long-term obligations.

    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.

OTHER EVENTS

    The Company  entered into a patent license  agreement with David  Fitzgerald
and Ira Pastan on April 28, 1998, and with the National  Institutes of Health on
May 7, 1998 (collectively the "Patent Agreements"). Under the Patent Agreements,
the Company obtained an exclusive  license covering the therapeutic  application
of an  anti-cancer  compound  referred to as  IL-4(38-37)-PE38KDEL  (IL-4 Fusion
Toxin).  The Company is obligated to make milestone  payments upon attainment of
certain clinical development and regulatory accomplishments and royalty payments
based  upon  sales  by the  Company  of  products  developed  under  the  Patent
Agreements.  During the quarter ended June 30, 1998, the Company initiated Phase
I human clinical trials with the anti-cancer compound in patients with malignant
brain tumors.

    On May 28, 1998, the Company acquired Northwest NeuroLogic,  Inc., an Oregon
corporation  ("NNL"). The Company purchased all of the outstanding capital stock
of NNL and assumed all of its outstanding  stock options in exchange for 392,608
shares of the Company's  Common Stock and options to purchase  105,414 shares of
Common Stock. The acquisition was accounted for as a purchase  transaction.  The
aggregate  purchase price of $4.2 million was allocated to the fair value of the
net assets acquired,  the majority of which was acquired in-process research and
development.  There can be no assurance  that the Company will be  successful in
developing  these compounds,  that they will receive  necessary FDA approvals to
proceed to the next phase of clinical  testing,  or that they will ultimately be
developed into commercially viable products.

    The Company's results of operations include NNL's results of operations from
the date of  acquisition.  There can be no  assurance  that the Company will not
incur additional charges in subsequent quarters to reflect costs associated with
the  transaction  or that the  Company  will be  successful  in its  efforts  to
integrate the operations of NNL into those of the Company.

    The Company may make further  acquisitions  and  investments  and enter into
further  collaborations,  joint ventures and strategic alliances,  some of which
may be material,  when it believes such transactions will complement its overall
business  strategy.   However,   such   transactions,   and  in  particular  the
acquisitions of research and  development  companies,  are inherently  risky and
there can be no assurance that the recently  completed  acquisition  or any such
future  transactions or joint ventures will be successful and will not adversely
affect the Company's business, operating results, or financial condition.

     On June 30, 1998, the Company  entered  into a Sublicense and  Development
Agreement (the "Sublicense  Agreement") with DOV  Pharmaceutical,  Inc. ("DOV").
Under the Sublicense Agreement,  the Company obtained an exclusive sublicense to
the patent  rights and know-how  relating to  NBI-34060,  a compound in clinical
development,  for the  treatment  of insomnia and all  therapeutic  indications.
Under the Sublicense  Agreement,  the Company will be responsible  for worldwide
development  and  commercialization  of this compound.  In conjunction  with the
Sublicense Agreement, the Company made an equity investment in DOV and will make
milestone payments based upon the attainment of certain clinical development and
regulatory  accomplishments.  DOV will also receive  royalties on the  worldwide
sales by the Company of approved products resulting from the  collaboration.  In
addition,  the Company  issued  warrants  (the  "Warrants")  exercisable  for an
aggregate of 75,000 shares of Common Stock at an exercise price of approximately
$8.04 per share upon the occurrence of certain events.

YEAR 2000 COMPLIANCE

    Although the Company believes its key financial, information and operational
systems are Year 2000  compliant,  there can be no assurances that other defects
will not be discovered in the future.  The Company is unable to control  whether
the firms and vendors it does business with currently,  and in the future,  will
have  systems  which are Year 2000  compliant.  The Company has not yet verified
that  the  parties  it  conducts  business  with are Year  2000  Compliant.  The
Company's  operations  could be  affected  to the extent  that firms and vendors
would be unable to provide services or ship products.  However,  management does
not believe the Year 2000 changes will have a material  impact on its  business,
financial condition or results of operations.

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   obtaining  and  enforcing  its  patents  and  patent  rights  of  others,
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 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.



PART II.  OTHER INFORMATION

Item 2.              CHANGES IN SECURITIES AND USE OF PROCEEDS

   On May 28, 1998, the Company acquired Northwest  NeuroLogic, Inc. ("NNL"), 
pursuant  to the  Agreement  and Plan of  Reorganization  dated May 1, 1998 (the
"Agreement").  In connection  with the acquisition of NNL, the Company issued an
aggregate of 392,608 shares of the Company's  Common Stock (the "Merger Shares")
to the  existing  stockholders  of NNL in  exchange  for all of the  outstanding
shares of capital  stock of NNL.  The Merger  Shares were issued  pursuant to an
exemption from the  registration  requirements of the Securities Act of 1933, as
amended  (the  "Securities  Act"),  afforded  by  Section  4  (2)  thereof.  The
stockholders of NNL had access to all relevant information regarding the Company
necessary to evaluate the investment and represented  that the shares were being
acquired for  investment  intent.  Additionally,  the  stockholders  of NNL were
provided  with  information   statements  prior  to  the  vote  to  approve  the
transaction.  There was no general  solicitation or advertising  involved in the
acquisition,   and  the  Company  used   reasonable  care  to  assure  that  the
stockholders of NNL were not  underwriters.  At the closing of the  acquisition,
the Company assumed the outstanding stock options held by NNL optionees based on
an exchange  ratio as set forth in the  Agreement.  The 105,414 shares of Common
Stock underlying the options were registered on a Registration Statement on Form
S-8 filed with the Commission on June 26, 1998.

    On June 30, 1998,  the Company  issued to certain  investors  warrants  (the
"Warrants") to purchase shares of Common Stock of the Company in connection with
the  Sub-License  and  Development   Agreement   between  the  Company  and  DOV
Pharmaceutical,  Inc. dated June 30, 1998. The Warrants are  exercisable  for an
aggregate of 75,000 shares of Common Stock at an exercise price of approximately
$8.04 per share.

                      AGREEMENT AND PLAN OF REORGANIZATION


         This AGREEMENT AND PLAN OF  REORGANIZATION  (this  "Agreement") is made
and  entered  into as of May 1,  1998  among  Neurocrine  Biosciences,  Inc.,  a
Delaware corporation  ("Parent"),  NBI Acquisition Corp., a Delaware corporation
and  a  wholly  owned   subsidiary  of  Parent  ("Merger  Sub"),  and  Northwest
NeuroLogic, an Oregon corporation (the "Company").

                                    RECITALS

         A. The Boards of Directors  of each of the  Company,  Parent and Merger
Sub believe it is in the best  interests  of each  Company and their  respective
stockholders  that Parent  acquire the Company  through the statutory  merger of
Merger Sub with and into the Company (the "Merger") and, in furtherance thereof,
have adopted this Agreement and approved the Merger.

         B. Pursuant to the Merger, among other things, and subject to the terms
and conditions of this Agreement,  (i) all of the issued and outstanding  shares
of capital  stock of the Company  ("Company  Capital  Stock") shall be converted
into the  right to  receive  shares of voting  Common  Stock of Parent  ("Parent
Common Stock") and (ii) all outstanding  options ("Company  Options") to acquire
or receive shares of Company  Capital Stock shall be converted into the right to
receive options ("Parent Options") to acquire Common Stock of Parent.

         C. A portion of the shares of Parent  Common  Stock and Parent  Options
otherwise  issuable by Parent in  connection  with the Merger shall be placed in
escrow by Parent,  the release of which amount shall be contingent  upon certain
events and conditions,  all as set forth in the Escrow Agreement  referred to in
Article VII hereof.

         D.  The  Company,   Parent  and  Merger  Sub  desire  to  make  certain
representations  and  warranties  and other  agreements in  connection  with the
Merger.

         E.  Certain  stockholders  of the  Company  have  executed  Voting  and
Non-Disposition Agreements.

         NOW,  THEREFORE,  in  consideration  of  the  covenants,  promises  and
representations set forth herein, and for other good and valuable consideration,

shall cease, and the Company shall continue as the surviving  corporation and as
a wholly owned  subsidiary of Parent.  The Company as the surviving  corporation

California, unless another place or time is agreed to by Parent and the Company.
The date upon which the  Closing  actually  occurs is herein  referred to as the
"Closing  Date." On the Closing Date,  the parties hereto shall cause the Merger
to be consummated by filing an Agreement of Merger (or like instrument) with the
Secretaries of State of the States of Delaware and Oregon (the  "Certificate  of
Merger"), in accordance with the relevant provisions of applicable law (the time
of  acceptance  by the  Secretary  of State of  Delaware  of such  filing  being
referred to herein as the "Effective Time").

         I.3  Effect  of the  Merger.  At the Effective Time, the effect of the
Merger  shall be as provided in the  applicable  provisions  of Delaware Law and
Oregon Law.  Without  limiting  the  generality  of the  foregoing,  and subject
thereto, at the Effective Time, all the property, rights, privileges, powers and
franchises   of  the  Company  and  Merger  Sub  shall  vest  in  the  Surviving
Corporation, and all debts, liabilities and duties of the Company and Merger Sub
shall become the debts, liabilities and duties of the Surviving Corporation.

until thereafter amended as provided by law and such Articles of Incorporation.

                  (b) Unless otherwise  determined by Parent,  the Bylaws of the
Company,  as in effect  immediately  prior to the Effective  Time,  shall be the
Bylaws of the Surviving Corporation until thereafter amended.

         I.5 Directors and OfficersI.5  Directors and OfficersI.5  Directors and

(including  Parent Common Stock to be reserved for issuance upon exercise of any
of the Company  Options to be assumed by Parent) in exchange for the acquisition
by Parent of all outstanding  Company Capital Stock and Company Options shall be
the Aggregate  Share Number (as defined in Section  1.6(g)(iii)).  No adjustment
shall be made in the  number  of shares of  Parent  Common  Stock  issued in the
Merger as a result of any cash  proceeds  received by the Company  from the date
hereof to the Effective  Time  pursuant to the exercise of options,  warrants or
other  rights  to  acquire  Company  Capital  Stock.  Subject  to the  terms and
conditions of this Agreement,  as of the Effective Time, by virtue of the Merger
and without  any action on the part of Merger Sub,  the Company or the holder of
any shares of the Company Capital Stock, the following shall occur:

                  (a) Conversion of Company Capital Stock. Each share of Company
Capital Stock issued and  outstanding  immediately  prior to the Effective  Time
(other  than any  shares of Company  Stock to be  canceled  pursuant  to Section
1.6(b) and any  Dissenting  Shares as  defined  and to the  extent  provided  in
Section 1.7(a)) will be canceled and extinguished and be converted automatically
into the right to  receive  (subject  to Section  1.8 with  regard to the Escrow
Amount) that number of shares of Parent Common Stock equal to the Exchange Ratio
(as defined in Section  1.6(g)(v)  below),  upon  surrender  of the  certificate
representing  such share of Company  Capital  Stock in the  manner  provided  in
Section 1.8.

                  (b) Cancellation of Parent-Owned and Company-Owned Stock. Each
share of Company Capital Stock owned by Merger Sub,  Parent,  the Company or any
direct or indirect wholly owned subsidiary of Parent or the Company  immediately
prior to the  Effective  Time shall be  canceled  and  extinguished  without any
conversion thereof.

                  (c) Stock  Options.  At the  Effective  Time,  all  options to
purchase Company Capital Stock then  outstanding  under the Company's 1997 Stock
Incentive  Plan (the "Option  Plan") or otherwise  shall be assumed by Parent in
accordance with provisions described below.



<PAGE>


                           (i)      At the Effective Time, each outstanding 
Company  Option under the Option Plan or otherwise,  whether vested or unvested,
shall be, in connection with the Merger,  assumed by Parent. Each Company Option
so assumed by Parent under this Agreement shall continue to have, and be subject
to,  the same  terms and  conditions  set  forth in the  Option  Plan  and/or as
provided in the  respective  option  agreements  governing  such Company  Option
immediately  prior to the Effective  Time,  except that: (A) such Company Option
shall be  exercisable  for that number of whole  shares of Parent  Common  Stock
equal to the product of the number of shares of Company  Capital Stock that were
issuable upon exercise of such Company Option immediately prior to the Effective
Time  multiplied  by the  Exchange  Ratio,  rounded down (in the case of Company
Options  granted under the Option Plan) to the nearest whole number of shares of
Parent Common Stock  (subject to Section 1.8 with regard to the Escrow  Amount),
(B) the per share  exercise price for the shares of Parent Common Stock issuable
upon  exercise of such  assumed  Company  Option  shall be equal to the quotient
determined by dividing the exercise price per share of Company  Capital Stock at
which such Company  Option was  exercisable  immediately  prior to the Effective
Time by the  Exchange  Ratio,  rounded up to the nearest  whole  cent,  (C) with
regard to Company  Options held by persons  listed on Schedule  1.9(a)  attached
hereto,  such Company  Option shall be subject to forfeiture in accordance  with
the vesting  schedules  set forth in Section 1.9  hereof,  and (D) such  Company
Option shall be exercisable  for a term equal to the lesser of (i) the remaining
term of the Company Option and (ii) five (5) years from the Effective Time.

                           (ii) It is the  intention  of the  parties  that  the
Company  Options  assumed by Parent  qualify  following  the  Effective  Time as
incentive  stock options as defined in Section 422 of the Code to the extent the
Company Options  qualified as incentive stock options  immediately  prior to the
Effective Time.
                  (d) Capital Stock of Merger Sub. Each share of Common Stock of
Merger Sub issued and outstanding  immediately prior to the Effective Time shall
be  converted  into  and  exchanged  for one  validly  issued,  fully  paid  and
nonassessable  share of Common  Stock of the  Surviving  Corporation.  After the
Effective Time, each stock certificate of Merger Sub evidencing ownership of any
such shares  shall  evidence  ownership  of such shares of capital  stock of the
Surviving Corporation.

                  (e) Adjustments to Exchange Ratio. The Exchange Ratio shall be
adjusted to reflect fully the effect of any stock split,  reverse  split,  stock
dividend (including any dividend or distribution of securities  convertible into
Parent Common Stock or Company Capital Stock), reorganization,  recapitalization
or other like  change with  respect to Parent  Common  Stock or Company  Capital
Stock occurring after the date hereof and prior to the Effective Time.

                  (f) Fractional Shares. No fraction of a share of Parent Common
Stock  will be issued,  but in lieu  thereof,  each  holder of shares of Company
Capital Stock who would otherwise be entitled to a fraction of a share of Parent
Common Stock (after  aggregating all fractional shares of Parent Common Stock to
be received by such  holder)  shall be entitled to receive from Parent an amount
of cash  (rounded  to the  nearest  whole cent) equal to the product of (i) such
fraction,  multiplied  by (ii)  $8.43333  (calculated  as set  forth in  Section
1.6(g)(vi).

                  (g)      Definitions.

                           (i)      Aggregate Common Number.  The "Aggregate 
Common Number" shall mean 591,250 (or the aggregate  number of shares of Company
Capital Stock outstanding immediately prior to the Effective Time).

Option Number" shall mean 158,750 (or the aggregate  number of shares of Company

Share Number" shall be 498,022  shares of Common Stock of Parent (which is equal
to $4,200,000 divided by the Market Price), as appropriately adjusted to reflect
the effect of any stock split, stock dividend, reorganization,  recapitalization
or the like with  respect to the Parent  Common Stock  occurring  after the date
hereof and prior to the Effective Time (a "Recapitalization of the Parent Common
Stock").

                           (iv)     Escrow Amount.  The "Escrow Amount" shall be
[***] shares of Parent  Common Stock (which is equal to the product  obtained by
multiplying (x) the sum of the Aggregate  Common Number and the Aggregate Option
Number by (y) the  Exchange  Ratio by (z)  [***].  The  Escrow  Amount  shall be
composed of [***] Vested  Securities  and [***].  Unvested  Securities as of the
Effective Time, as set forth on Schedule 1.6 attached hereto.

                           (v)      Exchange Ratio.  The "Exchange Ratio" shall 
be  0.66403  (which  is equal  to the  quotient  obtained  by  dividing  (x) the
Aggregate  Share Number by (y) the sum of (A) the  Aggregate  Common Number plus
(B) the Aggregate Option Number).

                           (vi)     Market Price.  The Market Price of the 
Parent  Common Stock shall mean $8.43333 per share of Parent Common Stock (which
is equal to the average  closing  price of a share of Parent  Common  Stock,  as
reported  on the Nasdaq  National  Market,  over the  fifteen  (15)  consecutive
trading days ending on the date  preceding the date of public  disclosure of the
Letter  Agreement  between Parent and the Company dated February 27, 1998, which
disclosure date was March 3, 1998).

                           (vii)    Vested Securities.  "Vested Securities"
means shares of Parent Common Stock,  Parent Options or Milestone Warrants which
are vested  pursuant to the vesting  schedule set forth in Section 1.9 as of the

                           (viii)   Unvested Securities.   "Unvested Securities"
means shares of Parent Common Stock,  Parent Options or Milestone Warrants which
are unvested pursuant to the vesting schedule set forth in Section 1.9 as of the
relevant time.

         I.7      Dissenting Shares

                  (a)  Notwithstanding  any  provision of this  Agreement to the
contrary,  any shares of Company Capital Stock held by a holder who has demanded
and perfected appraisal or dissenters' rights for such shares in accordance with
Oregon Law and who, as of the Effective Time, has not  effectively  withdrawn or
lost such appraisal or  dissenters'  rights  ("Dissenting  Shares") shall not be
converted  into or represent a right to receive  Parent Common Stock pursuant to
Section 1.6, but the holder thereof shall only be entitled to such rights as are
granted by applicable law.



<PAGE>


                  (b)  Notwithstanding  the provisions of subsection (a), if any
holder of shares of Company  Capital Stock who demands  appraisal of such shares
under Oregon Law shall effectively  withdraw or lose (through failure to perfect
or  otherwise)  the right to  appraisal,  then, as of the later of the Effective
Time and the occurrence of such event, such holder's shares shall  automatically
be converted  into and represent  only the right to receive  Parent Common Stock
and cash in lieu of  fractional  shares as  provided  in  Section  1.6,  without
interest thereon, upon surrender of the certificate representing such shares.

                  (c) The  Company  shall give  Parent (i) prompt  notice of any
written   demands  for  appraisal  of  any  shares  of  Company  Capital  Stock,
withdrawals of such demands, and any other instruments served pursuant to Oregon
Law and received by the Company and (ii) the  opportunity  to participate in all
negotiations  and proceedings with respect to demands for appraisal under Oregon
Law. The Company  shall not,  except with the prior  written  consent of Parent,
voluntarily  make any  payment  with  respect to any demands  for  appraisal  of
capital stock of the Company or offer to settle or settle any such demands.

         I.8      Surrender of Certificates

                  (a)      Exchange Agent.  American Stock Transfer & Trust
Company shall act as exchange agent (the "Exchange Agent") in the Merger.

                  (b)  Parent  to  Provide  Common  Stock.  Promptly  after  the
Effective  Time,  Parent shall make available to the Exchange Agent for exchange
in  accordance  with  this  Article  I and as set  forth on  Schedule  1.6,  the
aggregate  number of shares of Parent  Common  Stock  issuable in  exchange  for
outstanding  shares of Company Capital Stock or upon exercise of Parent Options;
provided,  however,  that on behalf of the holders of Company  Capital Stock and
Company Options,  Parent shall deposit into an escrow account a number of shares
of Parent Common Stock equal to the Escrow Amount out of the aggregate number of
shares of Parent Common Stock otherwise issuable pursuant to sections 1.6(a) and
1.6(c),  provided,  further,  that shares of Parent  Common Stock  issuable upon
exercise of the Parent  Options  shall not be  deposited  in the escrow  account
until  exercise of the relevant  Parent  Option.  Parent shall  deposit into the
escrow account  shares of Parent Common Stock issued  pursuant to Section 1.6(a)
promptly  after the  Effective  Time and shares of Parent  Common  Stock  issued
pursuant to the exercise of Parent Options promptly after exercise thereof.  The
portion of the Escrow  Amount  contributed  on behalf of each  holder of Company
Capital Stock and Company Options shall be in proportion to the aggregate number
of shares of Parent  Common  Stock and Parent  Options  which such holder  would
otherwise be entitled to receive under  sections  1.6(a) and 1.6(c) by virtue of
ownership of outstanding shares of Company Capital Stock and Company Options.



<PAGE>


                  (c) Exchange  Procedures.  Promptly after the Effective  Time,
the Surviving Corporation shall cause to be mailed to each holder of record of a
certificate or certificates (the "Certificates")  which immediately prior to the
Effective Time represented outstanding shares of Company Capital Stock and which
shares were  converted  into the right to receive  shares of Parent Common Stock
pursuant to Section 1.6, (i) a letter of  transmittal  (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon delivery of the  Certificates to the Exchange Agent and shall be
in such form and have such other  provisions as Parent may  reasonably  specify)
and (ii)  instructions for use in effecting the surrender of the Certificates in
exchange for  certificates  representing  shares of Parent  Common  Stock.  Upon
surrender of a Certificate  for  cancellation  to the Exchange  Agent or to such
other agent or agents as may be appointed by Parent,  together  with such letter
of  transmittal,  duly  completed and validly  executed in  accordance  with the
instructions  thereto,  the  holder of such  Certificate  shall be  entitled  to
receive in  exchange  therefor a  certificate  representing  the number of whole
shares of Parent Common Stock (less the number of shares of Parent Common Stock,
if any, (a) to be deposited in the Escrow Fund on such holder's  behalf pursuant
to the Escrow  Agreement  referred to in Article VII hereof,  and (b) subject to
transfer  restrictions  in connection  with the Company's  right to repurchase),
plus cash in lieu of fractional  shares in accordance with Section 1.6, to which
such  holder is  entitled  pursuant  to  Section  1.6,  and the  Certificate  so
surrendered  shall  forthwith  be  canceled.  As soon as  practicable  after the
Effective  Time,  and subject to and in  accordance  with the  provisions of the
Escrow  Agreement  referred to in Article VII hereof,  Parent  shall cause to be
distributed to the Escrow Agent (as defined in the Escrow Agreement  referred to
in Article VII) a certificate or certificates representing that number of shares
of Parent  Common Stock and Parent  Options  equal to the Escrow  Amount,  which
certificate  shall be registered in the names of the  stockholders  to whom such
shares would otherwise be issued. Such shares shall be beneficially owned by the
holders on whose behalf such shares were  deposited in the Escrow Fund and shall
be available to compensate  Parent as provided in the Escrow Agreement  referred
to in Article VII. Until so  surrendered,  each  outstanding  Certificate  that,
prior to the Effective Time, represented shares of Company Capital Stock will be
deemed from and after the Effective Time, for all corporate purposes, other than
the payment of dividends, to evidence the ownership of the number of full shares
of Parent  Common  Stock into which such shares of Company  Capital  Stock shall
have been so converted and the right to receive an amount in cash in lieu of the
issuance of any fractional shares in accordance with Section 1.6.

                  (d)  Distributions  With  Respect to  Unexchanged  Shares.  No
dividends or other distributions with respect to Parent Common Stock declared or
made after the Effective  Time and with a record date after the  Effective  Time
will be paid to the holder of any unsurrendered  Certificate with respect to the
shares of Parent Common Stock represented  thereby until the holder of record of
such Certificate  shall surrender such  Certificate.  Subject to applicable law,
following  surrender of any such Certificate,  there shall be paid to the record
holder of the  certificates  representing  whole  shares of Parent  Common Stock
issued in exchange  therefor,  without interest,  at the time of such surrender,
the amount of  dividends  or other  distributions  with a record  date after the
Effective Time  theretofore  payable with respect to such whole shares of Parent
Common Stock.



<PAGE>


                  (e) Transfers of Ownership.  If any  certificate for shares of
Parent  Common  Stock is to be  issued  in a name  other  than that in which the
Certificate  surrendered  in  exchange  therefor  is  registered,  it  will be a
condition of the issuance  thereof that the  Certificate so surrendered  will be
properly  endorsed and otherwise in proper form for transfer and that the person
requesting such exchange will have paid to Parent or any agent  designated by it
any transfer or other taxes  required by reason of the issuance of a certificate
for shares of Parent Common Stock in any name other than that of the  registered
holder of the  Certificate  surrendered,  or established to the  satisfaction of
Parent  or any  agent  designated  by it that  such tax has been  paid or is not
payable.

                  (f) No Liability.  Notwithstanding anything to the contrary in
this Section 1.8, none of the Exchange Agent,  the Surviving  Corporation or any
party  hereto  shall be liable to a holder of shares of Parent  Common  Stock or
Company Capital Stock for any amount properly paid to a public official pursuant
to any applicable abandoned property, escheat or similar law.

Repurchase of Parent Common StockI.9  Forfeiture and Repurchase of Parent Common
Stock.

pursuant to Section  1.6(a)  and/or  issuable  upon  exercise  of the  Milestone
Warrants shall be subject to the right of Parent to  repurchase,  and the Parent
Options  held by those  employees  and  consultants  of the  Company  listed  on
Schedule  1.9(a)  attached  hereto  shall be subject to the risk of  forfeiture,

         II.1  Organization of the  Company.  The Company is a corporation  duly
organized  and  validly  existing  under  the laws of the State of  Oregon.  The
Company  has the  corporate  power  to own its  properties  and to  carry on its
business as now being  conducted.  The Company is duly  qualified to do business
and in good standing as a foreign  corporation in each jurisdiction in which the
failure to be so qualified would have a material adverse effect on the business,
assets  (including  intangible  assets),   financial  condition  or  results  of
operations  of the  Company  (hereinafter  referred  to as a  "Material  Adverse
Effect").  The Company has  delivered a true and correct copy of its Articles of
Incorporation and Bylaws, each as amended to date, to Parent.

         II.2     Company Capital Structure

                  (a) As of the Closing Date,  the  authorized  capital stock of
the Company shall consist of 10,000,000  shares of authorized  Common Stock,  of
which 591,250 shares are issued and outstanding, 10,000,000 shares of authorized
Preferred  Stock,  of which no shares are issued and  outstanding,  and no other
shares of Capital Stock. As of the Closing Date, the Company Capital Stock shall
be held of record  by the  persons,  with the  addresses  of  record  and in the
amounts set forth on Schedule 2.2(a).  All outstanding shares of Company Capital

as of the date  hereof and the  Closing  Date,  158,750  shares  are  subject to
outstanding,  unexercised  options  and no shares  remain  available  for future
grant. The Company has reserved 158,750 shares of Common Stock for issuance upon

Schedule 2.2(b) sets forth for each  outstanding  Company Option the name of the

granted in all material  respects in compliance  with all applicable  securities
laws and all  other  applicable  legal  requirements.  Except  as  described  in

bound obligating the Company to issue,  deliver,  sell, repurchase or redeem, or

capital  stock of the  Company  or  obligating  the  Company  to grant,  extend,
accelerate  the vesting of, change the price of,  otherwise  amend or enter into
any such option, warrant, call, right,  commitment or agreement.  The holders of
Company Options have been or will be given, or shall have properly  waived,  any
required notice prior to the Merger.  As a result of the Merger,  Parent will be

Corporation and rights to acquire or receive such capital stock.

subsidiaries  or  affiliated  companies and does not otherwise own and has never
otherwise  owned any shares of capital  stock or any  interest  in, or  control,

both source code and object code form),  and tangible or intangible  proprietary
information  or  material  that  are  used in the  business  of the  Company  as

patents, registered and material unregistered trademarks, registered copyrights,
trade names and service marks,  and any applications  therefor,  included in the

issued  or  registered  or  in  which  an  application  for  such  issuance  and
registration   has  been  filed,   including  the  respective   registration  or
application  numbers and the names of all registered  owners.  Schedule  2.11(b)

person is authorized  to use any Company  Intellectual  Property  Right or trade
secret of the  Company,  and includes  the  identity of all parties  thereto,  a
description of the nature and subject matter thereof,  the applicable royalty or
other fees and the term thereof. The execution and delivery of this Agreement by
the Company, and the consummation of the transactions  contemplated hereby, will
neither  cause the Company to be in violation or default under any such license,
sublicense  or  agreement,  nor  entitle  any other  party to any such  license,
sublicense  or  agreement to terminate  or modify such  license,  sublicense  or
agreement.  Except as set forth in Schedules 2.11(a) or 2.11(b),  the Company is

                  (c)  No  claims  with  respect  to  the  Company  Intellectual
Property  Rights  have  been  asserted  or  are,  to  the  Company's  knowledge,
threatened  by any person,  nor are there any valid grounds for any such claims,
(i) to the effect that the  manufacture,  sale,  licensing  or use of any of the
products of the Company infringes on any copyright,  patent, trade mark, service
mark,  trade  secret or other  proprietary  right,  (ii)  against the use by the
Company  of  any  trademarks,   service  marks,   trade  names,  trade  secrets,

ownership  by the  Company,  validity  or  effectiveness  of any of the  Company
Intellectual  Property  Rights.  All  registered  trademarks,  service marks and
copyrights  held by the  Company are valid and  subsisting.  The Company has not
infringed, and the business of the Company as currently conducted or as proposed
to be conducted does not infringe,  any copyright,  patent,  trademark,  service
mark, trade secret or other  proprietary  right of any third party.  There is no
material  unauthorized  use,  infringement  or  misappropriation  of  any of the
Company Intellectual Property Rights by any third party,  including any employee
or former  employee of the Company.  No Company  Intellectual  Property Right or
product of the Company or any of its  subsidiaries is subject to any outstanding
decree, order, judgment, or stipulation  restricting in any manner the licensing
thereof by the  Company.  The  Company  has taken all  reasonable  measures  and
precautions  to protect and maintain the  confidentiality,  secrecy and value of
the  Company  Intellectual  Property  Rights.  Except as set  forth on  Schedule
2.11(c),  each current and former  employee,  consultant  or  contractor  of the
Company has executed a proprietary  information  and  confidentiality  agreement
substantially in the Company's  standard forms and in any event  restricting the
use and  disclosure of the Company  Intellectual  Property and providing for the
assignment  to the Company of Company  Intellectual  Property  developed by such
employees,  consultants and  contractors.  All software  included in the Company
Intellectual  Property  Rights is original  with the Company and has been either
created by employees of the Company on a  work-for-hire  basis or by consultants
or contractors  who have created such software  themselves and have assigned all
rights they may have had in such software to the Company.

power  and  authority  to  enter  into  this  Agreement  and to  consummate  the
transactions  contemplated  hereby. The execution and delivery of this Agreement

furnished  or made  available  to the Company  true and  complete  copies of all
reports or registration  statements filed by it with the Securities and Exchange
Commission (the "SEC") since December 31, 1996, all in the form so filed (all of
the foregoing  being  collectively  referred to as the "SEC  Documents").  As of
their  respective  filing  dates,  the SEC  Documents  complied in all  material
respects with the  requirements  of the Securities Act of 1933 (the  "Securities
Act") or the Securities  Exchange Act of 1934 (the  "Exchange  Act") as the case
may be,  and none of the SEC  Documents  contained  any  untrue  statement  of a

in which they were made,  not  misleading,  except to the extent  corrected by a
document  subsequently  filed with the SEC. The financial  statements of Parent,
including  the  notes  thereto,  included  in the  SEC  Documents  (the  "Parent
Financial  Statements")  comply  as  to  form  in  all  material  respects  with
applicable accounting  requirements and with the published rules and regulations
of the SEC with respect  thereto,  have been  prepared in  accordance  with GAAP
consistently applied (except as may be indicated in the notes thereto or, in the
case of unaudited statements,  as permitted by Form 10-Q of the SEC) and present

the  consolidated  results of its operations and cash flows for the periods then
ended  (subject,  in  the  case  of  unaudited   statements,   to  normal  audit
adjustments).  There has been no change in Parent accounting  policies except as
described in the notes to the Parent Financial  Statements;  provided,  however,
the Parent may have restated or may restate one or more of the Parent  Financial
Statements to reflect  acquisitions  entered into  subsequent to the  respective
dates thereof.

notice of assertion  against Parent,  which in any manner challenges or seeks to
prevent, enjoin, alter or materially delay any of the transactions  contemplated
by this Agreement.  Parent is not subject to any material  litigation  except as
disclosed in the SEC Documents.

when  used  herein  shall be deemed  in each  case to be  followed  by the words
"without  limitation."  The table of contents  and  headings  contained  in this
Agreement  are for  reference  purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

         IX.3 Counterparts.  This Agreement may be executed in one or more  
counterparts,  all of which shall be considered  one and the same  agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and  delivered  to the other  party,  it being  understood  that all
parties need not sign the same counterpart.

         IX.4 Entire Agreement;  Assignment.  This  Agreement,  the  Schedules 
and Exhibits  hereto,  and the documents and  instruments  and other  agreements
among the parties hereto referenced  herein: (a) constitute the entire agreement

         IX.5 Severability. In the event that any provision of this Agreement or
the  application  thereof,  becomes  or is  declared  by a  court  of  competent
jurisdiction  to be  illegal,  void  or  unenforceable,  the  remainder  of this
Agreement  will  continue in full force and effect and the  application  of such
provision to other persons or circumstances will be interpreted so as reasonably
to effect the intent of the parties hereto. The parties further agree to replace
such  void or  unenforceable  provision  of  this  Agreement  with a  valid  and
enforceable  provision that will achieve, to the extent possible,  the economic,
business and other purposes of such void or unenforceable provision.

         IX.6 Other  Remedies.  Except as otherwise provided herein,  any and 
all remedies herein expressly  conferred upon a party will be deemed  cumulative
with and not exclusive of any other remedy conferred hereby, or by law or equity
upon such party, and the exercise by a party of any one remedy will not preclude
the exercise of any other remedy.

IX.7  Governing  Law.  This  Agreement  shall be  governed by and  construed  in
accordance with the laws of the State of California, regardless of the laws that
might otherwise govern under applicable principles of conflicts of laws thereof.
Each of the parties  hereto  agrees that  process may be served upon them in any
manner  authorized by the laws of the State of  California  for such persons and
waives  and  covenants  not to assert or plead any  objection  which  they might
otherwise have to such jurisdiction and such process.

IX.8  Rules of  Construction.  The  parties  hereto  agree  that  they have been
represented  by counsel during the  negotiation  and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule of
construction  providing that  ambiguities in an agreement or other document will
be construed against the party drafting such agreement or document.

IX.9 Specific  Performance.  The parties  hereto agree that  irreparable  damage
would occur in the event that any of the  provisions of this  Agreement were not
performed in accordance with their specific terms or were otherwise breached. It
is  accordingly  agreed that the parties  shall be entitled to an  injunction or
injunctions to prevent  breaches of this  Agreement and to enforce  specifically
the terms and  provisions  hereof in any court of the United States or any state
having  jurisdiction,  this being in addition to any other  remedy to which they
are entitled at law or in equity.

1.       The license agreement between Oregon Health Sciences University and the

         a.       The  Company  needs to deduct  from its  earnings  the  spread
                  between the  exercise  price of all  discounted  options  that
                  vested during 1997 and the fair market value of the underlying
                  option shares at the time of vesting.

         b. Accrued vacation is not reflected in the Financial Statements.

         at the time of vesting.

3.       Contractual   obligations   (rather  than  liabilities   stemming  from
         breaches)  under  contracts  listed on Schedules  2.10(a),  2.11(b) and
         2.12(a).

4.       The Company has been awarded an NIH grant which will require  specified

                          REGISTRATION RIGHTS AGREEMENT


         This REGISTRATION  RIGHTS AGREEMENT (the "Agreement") is made as of May
28, 1998, by and among Neurocrine Biosciences, Inc., a Delaware corporation (the
"Parent") and the persons listed on the signature page who become signatories to
this Agreement  (collectively,  the "Investors and  individually an "Investor").
Capitalized terms not defined herein shall have the meanings ascribed to them in
the Agreement and Plan of Reorganization dated May 1, 1998.

                                 R E C I T A L S

         WHEREAS, in connection with the merger (the "Merger") of a wholly owned
subsidiary  of  Parent  with and into  Northwest  NeuroLogic,  Inc.,  an  Oregon
corporation  ("NNL") pursuant to the Agreement and Plan of Reorganization  dated
of even date  herewith,  Parent and the Investors  desire to provide for certain

         WHEREAS,  it is a  condition  of the  closing of the Merger that Parent

         NOW THEREFORE, in consideration of the promises set forth above and for

Investor or an assignee or  transferee  of  Registration  rights as permitted by
Section 8.

                  (d)  "Initiating  Holders"  shall  mean  Holders  who  in  the
aggregate  hold and propose to register  at least  [***]  shares of  Registrable
Securities.



<PAGE>


                  (e) "Material Adverse Event" shall mean an occurrence having a
consequence  that  either  (a)  is  materially   adverse  as  to  the  business,
properties,  prospects or financial condition of the Parent or (b) is reasonably
foreseeable,  has a reasonable likelihood of occurring,  and if it were to occur
would  materially  adversely  affect  the  business,  properties,  prospects  or
financial condition of the Parent.

                  (f) The  terms  "Register",  "Registered"  and  "Registration"
refer  to a  registration  effected  by  preparing  and  filing  a  registration
statement in compliance with the Securities Act ("Registration Statement"),  and

                  (g) "Registrable  Securities"  shall mean all shares of Parent
Common  Stock  issued or issuable to the  Investors  upon closing of the Merger,
including  Common Stock issued  pursuant to stock  splits,  stock  dividends and
similar distributions with respect to such shares, provided that such shares (i)
are not available for immediate  sale in the opinion of counsel to the Parent in
a transaction exempt from the registration and prospectus delivery  requirements
of the Securities Act so that all transfer  restrictions and restrictive legends
with respect  thereto are removed  upon  consummation  of such sale  pursuant to
Regulation S, Rule 144, or otherwise under applicable  federal  securities laws,
or (ii) have not previously been sold to the public.

                  (h)  "Registration  Expenses" shall mean all expenses incurred

such registration, other than Selling Expenses.

amended,  or any similar federal  statute,  and the rules and regulations of the

         2.       Demand Registration.



<PAGE>


                  2.1 Request for Registration on Form S-3. Subject to the terms
of this Agreement,  in the event that Parent receives from Initiating Holders at
any time  after the  Effective  Time and prior to the first  anniversary  of the
Effective  Time, a written  request that Parent effect any  Registration on Form
S-3 (or any successor form to Form S-3 regardless of its  designation) at a time
when Parent is eligible to  register  securities  on Form S-3 (or any  successor
form to Form S-3 regardless of its  designation)  for an offering of Registrable
Securities, the reasonably anticipated aggregate offering price to the public of
which would  exceed  [***],  Parent will  promptly  give  written  notice of the
proposed  Registration  to all the  Holders  and will,  as soon as  practicable,
effect  Registration  of the Registrable  Securities  specified in such request,
together  with all or such portion of the  Registrable  Securities of any Holder
joining in such request as are specified in a written  request  delivered to the
Parent  within 20 days after  written  notice  from the  Parent of the  proposed
Registration.  Parent  shall not be  obligated  to take any action to effect any
such  registration  pursuant to this Section 2.1: (i) prior to 90 days after the
Effective  Time,  (ii) subsequent to 365 days after the Effective Time, or (iii)
after Parent has effected one such Registration pursuant to this Section 2.1 and
such Registration has been declared effective and, if underwritten, has closed.

                  2.2 Right of Deferral  of  Registration.  If (i) Parent  shall
furnish to all such  Holders who joined in the request a  certificate  signed by
the President of Parent stating that, in the good faith judgment of the Board of
Directors  of  Parent,  it would be  seriously  detrimental  to  Parent  for any
Registration to be effected as requested under Section 2.1, or (ii) Parent shall
have effected a Registration  other than a Registration of securities  issued or
issuable  pursuant  to an employee  benefit  plan  (whether  or not  pursuant to
Section 2.1) within ninety (90) days preceding the date of such request,  Parent
shall  have the  right to defer  the  filing of a  Registration  Statement  with
respect to such  offering for a period of not more than (i) sixty (60) days from
delivery of the request of the Initiating  Holders,  or (ii) ninety (90) days of
the date of filing of such prior Registration respectively;  provided,  however,
that Parent may not utilize this right more than twice in any 12-month period.

                  2.3  Registration  of  Other   Securities.   Any  Registration
Statement  filed  pursuant to the request of the  Initiating  Holders under this
Section 2 may, subject to the provisions of Section 2.4,  include  securities of
Parent other than Registrable Securities.

                  2.4      Underwriting in Demand Registration.

                           2.4.1       Notice of Underwriting.  If the
Initiating  Holders intend to distribute the Registrable  Securities  covered by
their request by means of an underwriting, they shall so advise Parent as a part
of their  request made pursuant to this Section 2, and Parent shall include such
information in the written  notice  referred to in Section 2.1. The right of any
Holder to  Registration  pursuant to Section 2.1 shall be conditioned  upon such
Holder's agreement to participate in such underwriting and the inclusion of such
Holder's  Registrable  Securities in the underwriting (unless otherwise mutually
agreed by a majority in interest of the Initiating  Holders and such Holder with
respect to such participation and inclusion).

                           2.4.2       Inclusion of Other Holders in Demand
Registration.  If Parent,  officers or directors of Parent  holding Common Stock
other  than  Registrable  Securities,   or  holders  of  securities  other  than
Registrable  Securities (who are collectively  referred to as "Other  Holders"),
request inclusion in such Registration, the Initiating Holders shall, subject to
the  allocation  provisions  of Section  2.4.4 below,  on behalf of all Holders,
offer  to such  Other  Holders  that  such  securities  other  than  Registrable
Securities be included in the  underwriting,  conditioned upon the acceptance by
such Other  Holders of the terms of this Section 2. In event of the inclusion in
the  Registration of securities held by Other Holders,  such Other Holders shall
be deemed to be Holders for all purposes  under this  Agreement,  other than the
allocation provisions of Section 2.4.4 below.



<PAGE>


                           2.4.3       Selection of Underwriter in Demand 
Registration.  Parent shall  (together with all Holders  proposing to distribute
their  securities  through  such  underwriting)   enter  into  and  perform  its
obligations under an underwriting agreement in usual and customary form with the
representative   ("Underwriter's   Representative")   of  the   underwriter   or
underwriters  selected for such underwriting by the Holders of a majority of the
Registrable  Securities being registered by the Initiating Holders and consented
to by Parent (which consent shall not be unreasonably withheld).

                           2.4.4       Marketing Limitation in Demand 
Registration.   In  the  event  the  Underwriter's  Representative  advises  the
Initiating   Holders  in  writing  that  market  factors   (including,   without
limitation,  the  aggregate  number of shares of Common  Stock  requested  to be
Registered,  the general condition of the market,  and the status of the persons
proposing to sell securities pursuant to the Registration)  require a limitation
of the number of shares to be underwritten, then the Initiating Holders shall so
advise all Holders and Other  Holders,  and the number of shares of  Registrable
Securities and other  securities  that may be included in the  Registration  and
underwriting   shall  be  allocated  first  among  all  Holders  of  Registrable
Securities and Other Holders of securities  subject to contractual  registration
rights  and  second  among  all Other  Holders  of  securities  not  subject  to
contractual registration rights, in proportion, as nearly as practicable, to the
number of shares proposed to be included in such  Registration by such Holder or
Other Holder.  No Registrable  Securities or other securities  excluded from the
underwriting  by  reason  of  this  Section  2.4.4  shall  be  included  in such
Registration Statement.

                           2.4.5       Right of Withdrawal in Demand
Registration.  If any  Holder of  Registrable  Securities,  or a holder of other
securities  entitled  (upon  request)  to  be  included  in  such  Registration,
disapproves of the terms of the underwriting,  such person may elect to withdraw
therefrom  by  written  notice to Parent,  the  underwriter  and the  Initiating
Holders  delivered  at  least  seven  days  prior to the  effective  date of the
Registration Statement. The securities so withdrawn shall also be withdrawn from
the Registration Statement.

                  2.5  Blue  Sky in  Demand  Registration.  In the  event of any
Registration  pursuant to Section 2, Parent will exercise  reasonable efforts to
Register and qualify the securities covered by the Registration  Statement under
such other  securities  or Blue Sky laws of such  jurisdictions  as the  Holders
shall  reasonably  request  and as  shall  be  reasonably  appropriate  for  the
distribution of such  securities;  provided,  however,  that Parent shall not be
required to qualify to do  business  or to file a general  consent to service of
process in any such states or jurisdictions.

         3. Expenses of  Registration.  All  Registration  Expenses  incurred in
connection  with one  Registration  pursuant  to  Section  2.1 shall be borne by
Parent. However, Parent shall not be required to pay for any expenses of Holders
in connection with any registration  proceeding begun pursuant to Section 2.1 if
the registration request is subsequently withdrawn at the request of the Holders
of a majority of the  Registrable  Securities  to be registered  (which  Holders
shall bear such expenses);  provided,  however,  that (i) if at the time of such
withdrawal,  the Holders have learned of a Material  Adverse  Event not known to
the Holders at the time of their request or (ii) such withdrawal is made after a
deferral  of such  registration  by Parent  pursuant  to Section  2.2,  then the
Holders shall not be required to pay any of such expenses and shall retain their
rights  pursuant  to Section  2.1.  All Selling  Expenses  shall be borne by the
Holders  of the  securities  registered  pro rata on the basis of the  number of
shares registered.



<PAGE>


         4.  Registration  Procedures.   Parent  will  keep  each  Holder  whose
Registrable  Securities  are  included  in any  registration  pursuant  to  this
Agreement advised as to the initiation and completion of such  Registration.  At
its expense Parent will: (a) use  reasonable  efforts to keep such  Registration
effective for a period ending on the first  anniversary of the Effective Time or
until the Holder or Holders have  completed  the  distribution  described in the
Registration  Statement relating thereto (including  Registrable Securities that
will  be  released  from  lockup  agreements  after  the  effective  date of the
Registration),  whichever first occurs;  (b) furnish such number of prospectuses
(including  preliminary  prospectuses) and other documents as a Holder from time
to time  may  reasonably  request;  (c)  prepare  and  file  with  the SEC  such
amendments  and  supplements to such  registration  statement and the prospectus
used in  connection  with such  registration  statement  as may be  necessary to
comply with the provisions of the Securities Act with respect to the disposition
of all securities  covered by such registration  statement;  and (d) notify each
Holder of Registrable  Securities covered by such Registration  Statement at any
time when a prospectus  relating  thereto is required to be delivered  under the
Securities Act of the happening of any event as a result of which the prospectus
included in such Registration  Statement,  as then in effect, includes an untrue
statement of a material  fact or omits to state a material  fact  required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing.

         5. Information  Furnished by Holder. It shall be a condition  precedent
of Parent's  obligations  under this  Agreement  that each Holder of Registrable
Securities  included  in any  Registration  furnish to Parent  such  information
regarding such Holder and the distribution proposed by such Holder or Holders as
Parent may reasonably request.

         6.       Indemnification.

         6.1 Parent's  Indemnification  of Holders.  To the extent  permitted by
law,  Parent will  indemnify  each Holder,  each of its officers,  directors and
constituent  partners,  legal counsel and accountants for the Holders,  and each
person   controlling   such  Holder,   with   respect  to  which   Registration,
qualification or compliance of Registrable Securities has been effected pursuant
to this Agreement,  and each  underwriter,  if any, and each person who controls
any underwriter against all claims,  losses,  damages or liabilities (or actions
in respect  thereof) to the extent such claims,  losses,  damages or liabilities
arise  out  of or are  based  upon  any  untrue  statement  (or  alleged  untrue
statement) of a material  fact  contained in any  prospectus  or other  document
(including   any   related   Registration   Statement)   incident  to  any  such
Registration,  qualification  or  compliance,  or are based on any  omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading,  or any violation by
Parent of the Securities  Act, the  Securities  Exchange Act of 1934, as amended
(the  "1934  Act"),  or any  state  securities  law,  or any rule or  regulation
promulgated  under the Securities Act, the 1934 Act or any state securities law,
applicable  to Parent and  relating to action or inaction  required of Parent in
connection with any such Registration,  qualification or compliance;  and Parent
will reimburse each such Holder, each of its officers, directors and constituent
partners, legal counsel and accountants,  each such underwriter, and each person
who  controls  any such  Holder  or  underwriter,  for any  legal  and any other
expenses reasonably incurred,  as incurred,  in connection with investigating or
defending any such claim, loss, damage, liability or action; provided,  however,
that the indemnity contained in this Section 6.1 shall not apply to amounts paid
in settlement of any such claim, loss, damage, liability or action if settlement
is effected  without the consent of Parent (which consent shall not unreasonably
be withheld); and provided,  further, that Parent will not be liable in any such
case to the extent  that any such  claim,  loss,  damage,  liability  or expense
arises out of or is based  upon any  untrue  statement  or  omission  based upon
written information furnished to Parent by such Holder, its officers, directors,
constituent  partners,  legal counsel,  accountants,  underwriter or controlling
person and stated to be for use in connection with the offering of securities of
Parent.

                  6.2  Holder's   Indemnification   of  Parent.  To  the  extent
permitted  by law,  each Holder will,  if  Registrable  Securities  held by such
Holder  are  included  in  the   securities  as  to  which  such   Registration,
qualification  or  compliance  is being  effected  pursuant  to this  Agreement,
indemnify  Parent,  each of its directors  and officers,  each legal counsel and
independent  accountant  of the Parent,  each  underwriter,  if any, of Parent's
securities  covered by such a Registration  Statement,  each person who controls
Parent or such  underwriter  within the meaning of the Securities  Act, and each
other such Holder, each of its officers, directors,  constituent partners, legal
counsel and accountants and each person  controlling such other Holder,  against
all claims,  losses,  damages and  liabilities  (or actions in respect  thereof)
arising out of or based upon any untrue statement (or alleged untrue  statement)
by such Holder, of a material fact contained in any such Registration Statement,
prospectus,   offering  circular  or  other  document   (including  any  related
Registration  Statement)  incident to any such  Registration,  qualification  or
compliance,  or any  omission (or alleged  omission)  by such  Holder,  to state
therein a material fact  required to be stated  therein or necessary to make the
statements  therein  not  misleading,  or any  violation  by such  Holder of the
Securities  Act,  the  1934  Act or any  state  securities  law,  or any rule or
regulation  promulgated  under  the  Securities  Act,  the 1934 Act or any state
securities  law,  applicable  to such Holder and  relating to action or inaction
required of such Holder in connection with any such Registration,  qualification
or  compliance;  and  will  reimburse  Parent,  such  Holders,  such  directors,
officers,  partners,  persons, law and accounting firms, underwriters or control
persons for any legal and any other expenses reasonably  incurred,  as incurred,
in connection  with  investigating  or defending any such claim,  loss,  damage,
liability or action,  in each case to the extent,  but only to the extent,  that
such  untrue  statement  (or alleged  untrue  statement),  omission  (or alleged
omission)  or  violation  (or alleged  violation)  is made in such  Registration
Statement,  prospectus, offering circular or other document in reliance upon and
in conformity  with written  information  furnished to Parent by such Holder and
stated to be specifically  for use in connection with the offering of securities
of Parent,  provided,  however,  that each Holder's liability under this Section
6.2 shall not exceed such  Holder's net proceeds from the offering of securities
made in  connection  with such  Registration;  and provided,  further,  that the
indemnity  contained  in this  Section  6.2 shall not apply to  amounts  paid in
settlement of any such claim, loss, damage, liability or action if settlement is
effected without the consent of the Holder (which consent shall not unreasonably
be withheld).



<PAGE>


                  6.3  Indemnification  Procedure.  Promptly after receipt by an
indemnified  party  under this  Section 6 of notice of the  commencement  of any
action, such indemnified party will, if a claim in respect thereof is to be made
against an  indemnifying  party under this  Section 6,  notify the  indemnifying
party in  writing of the  commencement  thereof  and  generally  summarize  such
action.  The  indemnifying  party shall have the right to  participate in and to
assume the  defense of such claim,  jointly  with any other  indemnifying  party
similarly  noticed;  provided,  however,  that the  indemnifying  party shall be
entitled to select  counsel  for the defense of such claim with the  approval of
any  parties   entitled  to   indemnification,   which  approval  shall  not  be
unreasonably  withheld;   provided  further,   however,  that  if  either  party
reasonably  determines  that there may be a conflict  between  the  position  of
Parent and the  Investors  in  conducting  the defense of such  action,  suit or
proceeding  by reason of recognized  claims for indemnity  under this Section 6,
then  counsel  for such party  shall be  entitled  to conduct the defense to the
extent  reasonably  determined  by such  counsel to be  necessary to protect the
interest of such party. The failure to notify an indemnifying  party promptly of
the  commencement  of any such  action,  if  prejudicial  to the  ability of the
indemnifying party to defend such action, shall relieve such indemnifying party,
to the extent so  prejudiced,  of any liability to the  indemnified  party under
this  Section 6, but the omission so to notify the  indemnifying  party will not
relieve such party of any liability that such party may have to any  indemnified
party otherwise than under this Section 6.

         7. Reports Under Securities Exchange Act of 1934. With a view to making
available  to the  Investors  the  benefits  of Rule 144 and any  other  rule or
regulation  of the  Commission  that may at any time  permit an Investor to sell
securities  of  Parent to the  public  without  Registration  or  pursuant  to a
Registration on Form S-3, Parent agrees to use reasonable efforts to:

                  (a)      make and keep public information available, as those
terms are defined in Rule 144;

                  (b) file with the  Commission  in a timely  manner all reports
and other  documents  required of Parent under the  Securities  Act and the 1934
Act; and

                  (c) furnish to any Investor, so long as such Investor owns any
Registrable Securities, forthwith upon request (i) a written statement by Parent
that it has complied with the reporting requirements of Rule 144, the Securities
Act and the 1934 Act, or that it qualifies as a registrant  whose securities may
be  resold  pursuant  to Form  S-3,  (ii) a copy of the most  recent  annual  or
quarterly  report of Parent and such other  reports  and  documents  so filed by
Parent,  and (iii) such other  information  as may be  reasonably  requested  in
availing any Investor of any rule or regulation of the Commission  which permits
the selling of any such securities without registration.



<PAGE>


         8.  Transfer of Rights.  The  Registration  rights of the Investors set
forth in Section 2 may be assigned by any Holder to a transferee  or assignee of
any  Registrable  Securities  not sold to the public  acquiring  at least  [***]
shares of such  Holder's  Registrable  Securities  (equitably  adjusted  for any
recapitalizations, stock splits, combinations, and the like) or acquiring all of
the  Registrable  Securities  held by such  Holder  if  transferred  to a single
entity; provided,  however, that (i) Parent must receive written notice prior to
the time of said  transfer,  stating the name and address of said  transferee or
assignee and identifying  the securities with respect to which such  information
and Registration rights are being assigned,  and (ii) the transferee or assignee
of such  rights  must  not be a person  deemed  in good  faith  by the  Board of
Directors  of Parent to be a  competitor  or  potential  competitor  of  Parent.
Notwithstanding  the limitation set forth in the foregoing  sentence  respecting
the minimum  number of shares which must be  transferred,  any Holder which is a
partnership  may transfer  such  Holder's  Registration  rights to such Holder's
constituent partners (or may transfer to their heirs in the case of individuals)
without  restriction  as to the number or percentage  of shares  acquired by any
such constituent partner (or heirs).

         9.       Miscellaneous.

                  9.1 Entire Agreement;  Successors and Assigns.  This Agreement
constitutes the entire contract between Parent and the Investors relative to the
subject matter hereof. Subject to the exceptions  specifically set forth in this
Agreement, the terms and conditions of this Agreement shall inure to the benefit
of  and  be  binding  upon  the  respective  executors,  administrators,  heirs,
successors and assigns of the parties.

                  9.2  Governing  Law. This  Agreement  shall be governed by and
construed in accordance  with the laws of the State of California  applicable to
contracts entered into and wholly to be performed within the State of California
by California residents.

                  9.3  Counterparts.  This  Agreement  may be executed in two or
more counterparts,  each of which shall be deemed an original,  but all of which
together shall constitute one and the same instrument.

                  9.4 Notices.  Any notice required or permitted hereunder shall
be given in writing  and shall be  conclusively  deemed  effectively  given upon
personal delivery,  or five (5) days after deposit in the United States mail, by
first  class  mail,  postage  prepaid,  or upon  sending  if sent by  commercial
overnight  delivery  service  addressed  (i) if to  Parent,  as set forth  below
Parent's  name  on the  signature  page  of this  Agreement,  and  (ii) if to an
Investor,  at such Investor's address as set forth on the signature page of this
Agreement,  or at such other address as Parent or such Investor may designate by
ten  (10)  days'  advance   written  notice  to  the  Investors  or  to  Parent,
respectively.

                  9.5 Amendment of Agreement.  Except as otherwise  specifically
provided  herein,  any  provision of this  Agreement may be amended by a written
instrument signed by Parent and by persons holding more than fifty-five  percent
(55%)  of the  then  outstanding  Registrable  Securities  (calculated  on an as
converted basis).

                  9.6 Aggregation of Stock.  All Registrable  Securities held or
acquired by affiliated  entities or persons shall be aggregated together for the
purpose of determining the availability of any rights under this Agreement.

                  9.7  Severability.  If any provision of this Agreement is held
to be unenforceable  for any reason, it shall be adjusted rather than voided, if
possible,  in order to achieve the intent of the parties to the extent possible.
In any event,  all other  provisions of this Agreement shall be deemed valid and
enforceable to the full extent possible.

                          NEUROCRINE BIOSCIENCES, INC.

         THIS CERTIFIES  that,  for value  received,  _____________________,  is
entitled, upon the terms and subject to the conditions hereinafter set forth, at
any  time   after   ____________,   (the   "Effective   Date")   and   prior  to

("Exercise  Price") equal to the average of the closing  prices of the Company's
Common  Stock as  reported in the Wall  Street  Journal for the 15 trading  days
preceding  the  completion  of the Milestone (as such term is defined in Section

         2. Exercise of Warrant. The purchase rights represented by this Warrant
are  exercisable  by the registered  holder hereof,  in whole or in part, at any
time after the date hereof and prior to 4:00 p.m., La Jolla, California time, on
the  date of  termination  hereof  (as set  forth in  Section  10),  subject  to
adjustment  as  hereinafter  provided,  by the surrender of this Warrant and the
Notice of  Exercise  Form  annexed  hereto  duly  executed  at the office of the
Company, in La Jolla,  California (or such other office or agency of the Company
as it may designate by notice in writing to the registered  holder hereof at the
address of such holder appearing on the books of the Company),  and upon payment
of the Exercise Price for the shares  thereby  purchased (i) by cash or check or
bank  draft  payable  to the  order  of the  Company,  (ii) by  cancellation  of
indebtedness  of the  Company  payable  to the  holder  hereof  at the  time  of
exercise,  or (iii) by delivery of an election in writing to receive a number of
shares of Common Stock equal to the  aggregate  number of shares of Common Stock
subject  to this  Warrant  (or the  portion  thereof  being  canceled  upon such
exercise), less that number of shares of Common Stock having a fair market value
as of such date equal to the  aggregate  Exercise  Price of the Warrant (or such
portion  thereof)  whereupon  the holder of this  Warrant  shall be  entitled to
receive a certificate for the number of shares so purchased.  The Company agrees
that if, at the time of the  surrender of this Warrant (or portion  thereof) and
exercise  and  purchase as  aforesaid,  the holder  hereof  shall be entitled to
exercise  this  Warrant,  the shares so  purchased  shall be and be deemed to be
issued to such  holder  as the  record  owner of such  shares as of the close of
business  on the date on  which  this  Warrant  shall  have  been  exercised  as
aforesaid.

         Certificates for shares  purchased  hereunder shall be delivered to the
holder  hereof  within a  reasonable  time after the date on which this  Warrant
shall have been exercised as aforesaid.

         If this  Warrant  is  exercised  with  respect  to less than all of the
shares  covered  hereby,  the holder  hereof  shall be entitled to receive a new
Warrant,  in this form, covering the number of shares with respect to which this
Warrant shall not have been exercised.

         The Company covenants that all shares of stock which may be issued upon
the exercise of rights  represented  by this Warrant will,  upon exercise of the
rights represented by this Warrant,  be duly authorized,  validly issued,  fully
paid and nonassessable and free from all taxes,  liens and charges in respect of
the issue  thereof  (other  than  taxes in  respect  of any  transfer  occurring
contemporaneously with such issue).

         3. No  Fractional  Shares  or  Scrip.  No  fractional  shares  or scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant.

         4. Charges, Taxes and Expenses.  Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant  shall be made without  charge to
the holder hereof for any issue or transfer tax or other  incidental  expense in
respect of the  issuance of such  certificate,  all of which taxes and  expenses
shall be paid by the Company,  and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant;  provided,  however,  that in the event certificates for
shares of Common  Stock  are to be issued in a name  other  than the name of the
holder of this  Warrant,  this Warrant when  surrendered  for exercise  shall be
accompanied by the Assignment  Form attached  hereto duly executed by the holder
hereof; and provided further, that upon any transfer involved in the issuance or
delivery  of any  certificates  for  shares of Common  Stock,  the  Company  may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

         5. No Rights as Shareholders.  This Warrant does not entitle the holder
hereof to any voting  rights or other  rights as a  shareholder  of the  Company
prior to the exercise hereof.

         6. Exchange and Registry of Warrant. This Warrant is exchangeable, upon
the surrender hereof by the registered holder at the  above-mentioned  office or
agency of the  Company,  for a new  Warrant  of like  tenor and dated as of such
exchange.



<PAGE>


         7. Loss, Theft,  Destruction or Mutilation of Warrant. In case of loss,
theft or destruction or mutilation of this Warrant,  upon receipt by the Company
of evidence  reasonably  satisfactory to it of the loss,  theft,  destruction or
mutilation  of this  Warrant,  and in case of  loss,  theft or  destruction,  of
indemnity  or  security  reasonably   satisfactory  to  the  Company,  and  upon
reimbursement to the Company of all reasonable expenses incidental thereto,  and
upon surrender and cancellation of this Warrant, if mutilated,  the Company will
make and deliver a new Warrant of like tenor and dated as of such  cancellation,
in lieu of this Warrant.

         8. Saturdays,  Sundays, Holidays, etc. If the last or appointed day for
the  taking of any action or the  expiration  of any right  required  or granted
herein  shall be a Saturday or a Sunday or shall be a legal  holiday,  then such
action may be taken or such right may be  exercised on the next  succeeding  day
not a legal holiday.

         9.   Adjustment.   In  the  event  of  any  subdivision  or  change  or
subdivisions or changes of the shares of Common Stock of the Company at any time
while this  Warrant  is  outstanding  into a greater  number of shares of Common
Stock, the Company shall thereafter deliver at the time of purchase of shares of
Common Stock under this Warrant, in lieu of the number of shares of Common Stock
in respect of which the right to purchase is then being exercised,  such greater
number of  shares  of Common  Stock of the  Company  as would  result  from said
subdivision or change or  subdivisions or changes had the right of purchase been
exercised  before such  subdivision or change or subdivisions or changes without
the holder  making  any  additional  payment  or giving any other  consideration
therefor.  The number of shares for which this  Warrant is  exercisable  and the
time period for exercise are subject to adjustment from time to time as follows:

         In the event of any  consolidation or  consolidations  of the shares of
Common Stock of the Company at any time while this Warrant is outstanding into a
lesser number of shares of Common Stock, the Company shall  thereafter  deliver,
and the holder of this Warrant shall  accept,  at the time of purchase of shares
of Common  Stock under this  Warrant,  in lieu of the number of shares of Common
Stock in respect of which the right to  purchase is then being  exercised,  such
lesser number of shares of Common Stock of the Company as would result from such
consolidation or consolidations  had the right of purchase been exercised before
such consolidation or consolidations.

         In the event of any reclassification or reclassifications of the shares
of Common  Stock of the Company at any time while this  Warrant is  outstanding,
the Company shall thereafter deliver at the time of purchase of shares of Common
Stock under this Warrant the number of shares of the Company of the  appropriate
class or classes resulting from said  reclassification or  reclassifications  as
the holder would have been  entitled to receive in respect of purchase of shares
of  Common  Stock in  respect  of which  the  right of  purchase  is then  being
exercised had the right of purchase been exercised before such  reclassification
or reclassifications.



<PAGE>


         If the Company,  at any time while this Warrant is  outstanding,  shall
distribute any class of shares or rights,  options or warrants (other than those
referred to above) or  evidence of  indebtedness  or  property  (excluding  cash
dividends  paid in the ordinary  course) to holders of shares of Common Stock of
the Company, the number of shares to be issued by the Company under this Warrant
shall, at the time of purchase,  be appropriately  adjusted and the holder shall
receive,  in lieu of the  number  of  shares  in  respect  of which the right to
purchase  is then  being  exercised,  the  aggregate  number  of shares or other
securities  or property that the holder would have been entitled to receive as a
result of such event if, on the  record  date  thereof,  the holder has been the
registered  holder of the  number of shares of Common  Stock to which the holder
was theretofore entitled upon exercise of the rights of the holder hereunder.

         If the Company,  at any time while this Warrant is  outstanding,  shall
pay any stock dividend or stock dividends upon shares of stock of the Company of
the class or classes in  respect  of which the right to  purchase  is then given
under this  Warrant,  then the Company shall  thereafter  deliver at the time of
purchase of shares  under this  Warrant,  in addition to the number of shares of
stock of the  Company in respect  of which the right of  purchase  is then being
exercised,  the additional  number of shares of the appropriate class or classes
as would have been payable on the shares of stock of the Company so purchased if
the shares so purchased had been  outstanding on the record date for the payment
of the said stock dividend or stock dividends.

         On  the  happening  of  each  and  every  such  event,  the  applicable
provisions  of  this  Warrant  shall,  ipso  facto,  be  deemed  to  be  amended
accordingly and the Company shall take all necessary action so as to comply with
such provisions as so amended.

         10.  Termination.  This Warrant shall  terminate on the earlier of: (a)
_________________,  2008,  or (b)  the  voluntary  or  involuntary  dissolution,
liquidation,  winding up of the Company, sale of all or substantially all of the
assets of the Company, or a merger,  consolidation or acquisition of the Company
in which the stockholders of the Company prior to such merger,  consolidation or
acquisition  receive cash or securities of another  corporation which results in
the Company's  stockholders  not holding (by virtue of such shares or securities
issued  solely with  respect  thereto)  at least 50% of the voting  power of the
surviving, continuing or purchasing entity, provided, however, that in the event
any such event or transaction described in Section 10(b) hereof is proposed, the
Company shall give at least 20 days prior written  notice  thereof to the holder
hereof,  stating the  approximate  date on which such event is to take place and
the  approximate  date (which shall be at least 20 days after the giving of such
notice) as of which the owners of the Common  Stock of record  shall be entitled
to exchange their Common Stock for securities or other property deliverable upon
such  event.  Such  notice  shall  provide  for  the  release  of the  Company's
repurchase  right with respect to shares  issuable upon exercise of this Warrant
so that such shares shall no longer be subject to  repurchase  as of the closing
of such transaction.  If any such event or transaction shall occur, this Warrant
and all rights with  respect  hereto  shall  terminate on the date such event or
transaction  is closed.  Notices  pursuant to this  paragraph  shall be given by
certified mail, return receipt requested,  addressed to the holder hereof at the
holder's address in the Company's  records,  or such other address as the holder
hereof shall advise the Company in writing.

         11.  Registration  Rights.  The shares  issuable  upon exercise of this
Warrant  shall be  included in the  Company's  existing  piggyback  registration
rights,  provided that the requisite consent of the other holders of registrable
securities  of the  Company  can be  obtained.  The  Company  agrees  to use its
reasonable efforts to obtain such consent.
 12.     Miscellaneous.

                  (a)  Issue  Date.  The  provisions  of this  Warrant  shall be
construed and shall be given effect in all respects as if it had been issued and
delivered by the Company on the date hereof.  This  Warrant  shall  constitute a
contract under the laws of the State of California and for all purposes shall be
construed in accordance with and governed by the laws of said state.

                  (b)  Restrictions.  The holder  hereof  acknowledges  that the
Common Stock acquired upon the exercise of this Warrant shall have  restrictions
upon its resale imposed by state and federal securities laws.

                  (c) Authorized  Shares.  The Company covenants that during the
period the Warrant is  exercisable,  it will  reserve  from its  authorized  and
unissued Common Stock a sufficient  number of shares to provide for the issuance
of Common Stock upon the exercise of any purchase rights under this Warrant. The
Company  further  covenants  that its issuance of this Warrant shall  constitute
full authority to its officers who are charged with the duty of executing  stock
certificates to execute and issue the necessary  certificates  for shares of the
Company's  Common  Stock upon the  exercise of the  purchase  rights  under this
Warrant.

                  (d) No  Impairment.  The Company will not, by amendment of its
Articles of Incorporation or any other voluntary action,  avoid or seek to avoid
the observance or  performance of any of the terms of this Warrant,  but will at
all times in good faith  assist in the carrying out of all such terms and in the
taking  of all such  actions  as may be  necessary  or  appropriate  in order to

made,  used,  or sold and  Licensed  Processes  practiced  under this  Agreement
appropriate  to determine the amount of royalties due PHS. Such records shall be
retained for at least [***] years following a given reporting  period.  Upon the
written  request of PHS,  and not more than once per calendar  year,  unless PHS
determines  there is reason(s) for more  frequent  inspections,  Licensee  shall
permit an accountant or other designated auditor selected by PHS to inspect such
records for the sole purpose of verifying reports and payments  hereunder at the
expense of PHS. The accountant or auditor shall only disclose to PHS infonnation

an inspection shows an underreporting or underpayment in excess of [***] for any
twelve (12) month period,  then Licensee shall reimburse PHS for the cost of the
inspection  at the time Licensee pays the  unreported  royalties,  including any
late  charges as required by  Paragraph  10.08 of this  Agreement.  All payments
required under this  Paragraph  shall be due within thirty (30) days of the date
PHS provides Licensee notice of the payment due.

least  every two years if  annual  sales of the  Licensed  Product  or  Licensed
Processes are over [***]  dollars.  The audit shall address,  at a minimum,  the
amount of gross sales by or on behalf of Licensee  during the audit period,  the
amount of funds owed to the  Government  under this  Agreement,  and whether the
amount owed has been paid to the  Government  and is reflected in the records of
the  Licensee.  A report by the auditor  shall be  submitted  promptly to PHS on
completion.  Licensee  shall  pay for the  entire  cost of the  audit,  however,
Licensee  may  credit  [***] of such  costs for the  audit  against  any  future
royalties due to PHS under this Agreement.

10.01  Prior  to  signing  this  Agreement,  Licensee  has  provided  to PHS the
Commercial  Development Plan attached and/or as Appendix F, under which Licensee
intends to bring the subject  matter of the Licensed  Patent Rights to the point
of Practical  Application.  This Commercial  Development Plan is attached and/or
hereby  incorporated  by  reference  into this  Agreement.  Based on this  plan,
performance Benchmarks are determined as specified in Appendix E.

10.02 Licensee shall provide  written annual reports on its product  development
progress or efforts to commercialize  under the Commercial  Development Plan for
each of the Licensed  Fields of Use within sixty (60) days after  December 31 of

progress on research and  development,  status of  applications  for  regulatory
approvals,  manufacturing,   sublicensing,   marketing,  and  sales  during  the
preceding  calendar  year, as well as plans for the present  calendar  year. PHS
also encourages these reports to include information on any of Licensee's public
service  activities  that  relate to the  Licensed  Patent  Rights.  If reported
progress  differs from that  projected in the  Commercial  Development  Plan and
Benchmarks,  Licensee shall explain the reasons for such  differences.  Licensee
agrees to provide  any  additional  information  reasonably  required  by PHS to
evaluate Licensee's performance under this Agreement. PHS shall not unreasonably
withhold  approval of any request of Licensee to extend the time periods of this
schedule if such request is  supported  by a  reasonable  showing by Licensee of
diligence in its performance  under the Commercial  Development  Plan and toward
bringing the Licensed Products to the point of Practical

10.03 Licensee shall report to PHS the date of the First Commercial Sale in each
country in the Licensed Territory within thirty (30) days of such occurrence.

10.04  Licensee  shall  submit to PHS within  sixty (60) days after each [***] a
royalty  report setting forth for the preceding  half-year  period the amount of
the Licensed  Products sold or Licensed  Processes  practiced by or on behalf of
Licensee in each country within the Licensed  Territory,  the Net Sales, and the
amount of royalty accordingly due. With each such royalty report, Licensee shall
submit payment of the earned  royalties  due. If no earned  royalties are due to
PHS for any reporting  period,  the written  report shall so state.  The royalty
report shall be certified as correct by an  authorized  of ficer of Licensee and
shall include a detailed  listing of all deductions made under Paragraph 2.10 to
determine Net Sales made under Article 7 to determine royalties due.

10.05 Licensee agrees to forward [***] to PHS a copy of such reports received by
Licensee from its  sublicensees  during the  preceding  [***] period as shall be
pertinent to a royalty  accounting to PHS by Licensee for  activities  under the
sublicense.

10.06  Royalties  due  under  Article  6 shall  be paid  in  U.S.  dollars.  For
conversion of foreign currency to U.S. dollars, the conversion rate shall be the
New York foreign exchange rate quoted in The Wall Street Journal on the day that
the payment is due. All checks and bank drafts  shall be drawn on United  States
banks and shall be  payable,  as  appropriate,  for FDA or NIH  licenses  to the
National  Institutes  of  Health,  P.O.  Box  360120,  Pittsburgh,  Pennsylvania
15251-6120.  Any loss of exchange,  value,  taxes, or other expenses incurred in
the transfer or conversion  to U.S.  dollars shall be paid entirely by Licensee.
The royalty report  required by Paragraph 9.04 of this Agreement shall accompany
each such  payment and a copy of such report  shall also be mailed to PHS at its
address for notices indicated on the Signature Page of this Agreement.

10.07  The  parties  acknowledge  that  Licensee  and  its  sublicensees  may be
obligated to pay taxes, fees, assessments or other charges imposed by government
authorities  (the "Charges") up on royalty  payments  payable in connection with
the sale of Licensed  Products.  Licensee and its sublicensees shall provide PHS
with documentation  regarding the Charges and the payment of such Charges to the
appropriate governmental authorities. Licensee and its sublicensees shall deduct
all such  Charges  from the royalty  payments  due in  Paragraph  7.03 and shall
provide a listing of all such  Charges in the  royalty  report due in  Paragraph
10.04.   Licensee  shall  pay  the  Charges  to  the  appropriate   governmental
authorities.  Licensee shall promptly  provide PHS with any documents  which may
reasonably be necessary for PHS to obtain any credit to which it may be entitled
with respect to the Charges.

10.08 Late  charges  will be  assessed  by PHS as  additional  royalties  on any
overdue payments at a rate of [***] percent per month compounded monthly.  The
payment of such late  charges  shall not prevent PHS from  exercising  any other
rights it may have as a consequence of the lateness of any payment.

10.09 All plans and reports required by this Article 10 and marked confidential"
by  Licensee  shall,  to the  extent  permitted  by law,  be  treated  by PHS as
commercial  and financial  information  obtained from a person and as privileged
and  confidential  and any proposed  disclosure of such records by the PHS under
the  Freedom  of  Information  Act,  5  U.S.C.  552  shall  be  subject  to  the
predisclosure notification requirements of 45 CFR 5.65(d).

11.  PERFORMANCE

11.01  Licensee  shall use its  reasonable  best  efforts  to bring the  License
Products and  Licensed  Processes to  Practical  Application.  "Reasonable  best
efforts" for the purposes of this provision shall include  Licensee's good faith
attempts to adhere to the Commercial  Development Plan at Appendix F and perform
the Benchmarks at Appendix E.
The efforts of a sublicensee shall be considered the efforts of Licensee.

11.02 Upon the First  Commercial  Sale,  until the expiration of this Agreement,
Licensee  shall use its  reasonable  best efforts to make Licensed  Products and
Licensed Processes reasonably accessible to the United States public.

12.      INFRINGEMENT AND PATENT ENFORCEMENT

12.01 PHS and Licensee agree to notify each other promptly of each  infringement
or possible  infringement  of the Licensed  Patent Rights,  as well as any facts
which may affect the validity,  scope, or  enforceability of the Licensed Patent
Rights of which either Party becomes aware.

12.02  Pursuant to this  Agreement and the provisions of Chapter 29 of title 35,
United  States  Code,  Licensee  may a) bring  suit in its own name,  at its own
expense,  and on its own behalf for  infringement of presumably  valid claims in
the Licensed Patent Rights; b) in any such suit, enjoin infringement and collect
for its use,  damages,  profits,  and awards of whatever nature  recoverable for
such  infringement;  and c)  settle  any claim or suit for  infringement  of the
Licensed Patent Rights  provided,  however,  that [***]. If Licensee  desires to
initiate a suit for Patent infringement Licensee shall notify PHS in writing. If
PHS does not [***]. PHS shall have a continuing right to intervene in such suit.
Licensee shall take no action to compel the Government  either to initiate or to
join in any  such  suit  for  Patent  infringement.  Licensee  may  request  the
Government to initiate or join in any such suit if necessary to avoid  dismissal
of the suit.  Should the  Government be made a party to any such suit,  Licensee
shall  reimburse  the  Government  for any  costs,  expenses,  or fees which the
Government incurs as a result of such motion or other action,  including any and
all costs  incurred by the Government in opposing a such motion or other action.
In all cases,  Licensee  agrees to keep PHS  reasonably  apprised  of status and
progress of any litigation.  Before Licensee  commences an infringement  action,
Licensee shall notify PHS and give careful consideration to the views of PHS and
to any  potential  effects of the  litigation  on the public  health in deciding
whether to bring suit.

12.03 In the event that a declaratory  judgment  action  alleging  invalidity or
non-infringement  of any of the Licensed  Patent Rights shall be brought against
Licensee  or  raised  by  way  of  counterclaim  or  affirmative  defense  in an
infringement  suit brought by Licensee under Paragraph  12.02,  pursuant to this
Agreement  and the  provisions  of Chapter 29 of Title 35, United States Code or
other  statutes,  Licensee  may a) defend  the suit in its own name,  at its own
expense,  and on its own  behalf for  presumably  valid  claims in the  Licensed
Patent Rights;  b) in any such suit,  ultimately to enjoin  infringement  and to
collect for its use, damages, profits, and awards of whatever nature recoverable
for such infringement;  and c) settle any claim or suit for declaratory judgment
involving the Licensed Patent Rights-provided, however, that PHS and appropriate
Government  Patent License  Agreement  authorities shall have the first right to
take such actions and shall have a  continuing  right to intervene in such suit.
If PHS does not notify  Licensee  of its  intent to respond to the legal  action
within sixty (60) days,  Licensee will be free to do so.  Licensee shall take no
action to  compel  the  Government  either  to  initiate  or to join in any such
declaratory judgment action.  Licensee may request the Government to initiate or
to join any such suit if  necessary to avoid  dismissal of the suit.  Should the
Government  be made a party to any such suit by  motion  or any other  action of
Licensee,  Licensee shall reimburse the Government for any costs,  expenses,  or
fees which the Government  incurs as a result of such motion or other action. If
Licensee elects not to defend against such declaratory  judgment action, PHS, at
its option, may do so at its own expense. In all cases,  Licensee agrees to keep
PHS  reasonably  apprised of the status and progress of any  litigation.  Before
Licensee  commences an infringement  action,  Licensee shall notify PHS and give
careful  consideration  to the views of PHS and to any potential  effects of the
litigation on the public health in deciding whether to bring suit.

12.04 In any action under Paragraphs  12.02 or 12.03 initiated by Licensee,  the
expenses including costs, fees, attorney fees, and disbursements,  shall be paid
by  Licensee.  [***].

12.05 PHS shall  cooperate  fully with  Licensee in  connection  with any action
under  Paragraphs  12.02 or 12.03.  PHS agrees promptly to provide access to all
necessary documents and to render reasonable assistance in response to a request
by Licensee.

manufacture,  use  or  sale  of  Licensed  Product(s)  or the  use  of  Licensed
Process(es).

13.03 PHS does not warrant the validity of the Licensed  Patent Rights and makes
no  representations  whatsoever  with regard to the scope of the Licensed Patent

injury,  illness,  or  property  damage in  connection  with or  arising  out of
activities  performed subsequent to the execution of the Agreement of a) the use

reasonable  business practices and judgment and the ar~nual reports submitted by
Licensee under  Paragraph  10.02.  Prior to invoking this right,  PHS shall give
written notice to Licensee  providing  Licensee specific notice of, and a ninety
(90) day  opportunity  to respond to, PHS's concerns as to the previous items 1)

have  the  right  to  require  Licensee  to  grant  sublicenses  to  responsible
applicants,  on  reasonable  terms,  in any  Licensed  Fields  of Use  under the
Licensed Patent Rights,  unless  Licensee  can'reasonably  demonstrate  that the
granting of the sublicense would not materially increase the availability to the

Licensee.

excuse a similar  subsequent  failure to perform any such term or  condition  by
Licensee.

15.02 This  Agreement  constitutes  the entire  agreement  between  the  Parties
relating to the subject  matter of the  Licensed  Patent  Rights,  and all prior

               PASTAN/FITZGERALD AND NEUROCRINE BIOSCIENCES, INC.
                            PATENT LICENSE AGREEMENT


PATENT  LICENSE  AGREEMENT  dated as of April 28,  1998,  between Ira Pastan and
David J. FitzGerald (collectively, "Licensor") and Neurocrine Biosciences, Inc.,
a California  corporation having an office at 3050 Science Park Road, San Diego,
California 92121 ("Licensee").

Licensor and Licensee agree as follows:


1.     DEFINITIONS

       1.01     "Affiliate" of either party to this Agreement  means any person,
                firm,  or  corporation  which  controls,  is controlled by or is
                under common  control with such party.  Control means either the
                direct or indirect  ownership  of forty eight  percent  (48%) or
                more of the voting stock of the subject entity.

       1.02     "Licensed  Patent Rights" means patent  applications and patents
                listed in Appendix A (together with all counterpart applications
                and  patents in other  countries,  if any),  all  divisions  and
                continuations  of these  applications,  all patents issuing from
                such  applications,   divisions,  and  continuations,   and  any
                reissues, reexaminations, and extensions of all such patents.

                For the avoidance of doubt,  counterpart patent applications and
                patents  in the  United  States  are not owned by  Licensor  and
                therefore are not included in Licensed Patent Rights.

       1.03     "Licensed  Product(s)"  means tangible  materials  which, in the
                course of manufacture, use or sale would, in the absence of this
                Agreement,  infringe one or more claims of the  Licensed  Patent
                Rights that have not been held  invalid or  unenforceable  by an
                unappealed  or  unappealable  judgment  of a court of  competent
                jurisdiction.

       1.04     "Licensed Territory" means all countries in the world, excluding
                 the United States.

       1.05     "Licensor Representative" means Dr. David FitzGerald, who is 
                 authorized to act on behalf of Licensor in connection with this
                 Agreement.

       1.06     "Net Sales" means the total gross receipts for sales of Licensed
                Products by or on behalf of Licensee or its sublicensee and from
                leasing,   renting,   or  otherwise  making  Licensed   Products
                available to others without sale or other dispositions,  whether
                invoiced or not, less returns and allowances  actually  granted,
                packing  costs,  insurance  costs,  freight out, taxes or excise
                duties  imposed on the  transaction  (if  separately  invoiced),
                wholesaler and cash discounts in amounts customary in the trade,
                credits,  chargebacks,  rebates or refunds  incurred  or granted
                pursuant to legal or  contractual  requirements.  No  deductions
                shall be made for commissions paid to individuals,  whether they
                be with  independent  sales  agencies or  regularly  employed by
                Licensee and on its payroll, or for the cost of collections. For
                the avoidance of doubt, sales of Licensed  Products,  whether or
                not  manufactured  in the  Licensed  Territory  pursuant  to the
                license  hereunder,  in the United  States (which is not part of
                the Licensed Territory) shall not give rise to Net Sales for all
                purposes of the Agreement.

       1.07     "First  Commercial  Sale"  means the  initial  transfer by or on
                behalf of Licensee of Licensed  Products in exchange for cash or
                some  equivalent  to which value can be assigned for the purpose
                of determining Net Sales.

       1.08     "Licensed  Fields of Use" means IL-4 conjugated with pseudomonas
                exotoxin for the therapeutic treatment of cancer.


2.    GRANT OF RIGHTS

       2.01     Licensor  hereby  grants and  Licensee  accepts,  subject to the
                terms and conditions of this Agreement,  an exclusive license to
                Licensee  under  the  Licensed  Patent  Rights  in the  Licensed
                Territory  to make and have made,  to use and have used,  and to
                sell and have sold any Licensed  Products in the Licensed Fields
                of Use.

       2.02     Licensee  shall  have  the  right  to  grant  sublicenses.   Any
                sublicenses   granted  by   Licensee   shall   provide  for  the
                termination  of the  sublicense,  or the conversion to a license
                directly between such sublicensee and Licensor, at the option of
                the  sublicensee,  upon  termination  of  this  Agreement.  Such
                conversion is subject to the approval of Licensor and contingent
                upon acceptance by the  sublicensee of the remaining  provisions
                of this Agreement.

       2.03     Licensor  hereby  grants  Licensee the exclusive  option,  for a
                period of two (2) years from the completion of Phase II clinical
                trials,  to  obtain  an  exclusive  license  to  the  use of the
                Licensed  Patent  Rights for IL-4  conjugated  with  pseudomonas
                exotoxin in all therapeutic applications outside of the Licensed
                Fields  of Use.  In the event  that  Licensee  provides  written
                notice to Licensor of its desire to exercise such an option, the
                parties shall meet and negotiate in good faith the terms of such
                a license.  If the  parties  cannot  agree upon the terms of the
                license   within   ninety   (90)  days   after   entering   such
                negotiations,  Licensor  shall be free to license such  Licensed
                Patent Rights to a third party upon terms no more favorable than
                those last offered to Licensee.

       2.04     This  Agreement  confers no  license  or rights by  implication,
                estoppel,  or otherwise under any patent applications or patents
                of Licensor other than the Licensed Patent Rights  regardless of
                whether  such patents are  dominant or  subordinate  to Licensed
                Patent Rights.


3.     ROYALTIES AND REIMBURSEMENT

       3.01     Licensee  agrees to pay to Licensor a license  issue royalty and
                certain  milestone  payments  as set forth in  Appendix B within
                thirty  (30)  days from the date  that  this  Agreement  becomes
                effective or the applicable  milestone is achieved,  as the case
                may be.

       3.02     Licensee  agrees  to pay to  Licensor  a  nonrefundable  minimum
                annual  royalty as set forth in Appendix  B. The minimum  annual
                royalty  is due and  payable  on each  anniversary  of the  date
                hereof for a period not to exceed three (3) years.

       3.03     Licensee  agrees  to pay to  Licensor  earned  royalties  as set
                forth in Appendix B.

       3.04     Licensee agrees to pay to Licensor an option fee as set forth 
                in Appendix B for the second year of the exclusive option 
                outlined in Section 2.03.  Licensee will notify Licensor of its 
                intention to maintain  the option for the second year and will 
                pay the fee within  thirty (30) days of  completion of the first
                year of the exclusive option.

       3.05     A claim of a patent licensed under this Agreement shall cease to
                fall  within  the  Licensed  Patent  Rights  for the  purpose of
                computing the minimum annual royalty and earned royalty payments
                in any given  country on the  earliest  of the dates that a) the
                claim  has  been  abandoned  but not  continued,  b) the  patent
                expires,  c) the patent is no longer maintained by the Licensor,
                d) all claims of the Licensed Patent Rights have been held to be
                invalid  or  unenforceable  by  an  unappealed  or  unappealable
                decision of a court of competent  jurisdiction or administrative
                agency,  or e) it has been pending longer than the later of: (i)
                seven (7) years from the date of filing of the earliest asserted
                priority  patent  application;  or (ii) seven (7) years from the
                date of the request for examination in a country in which such a
                request is necessary.

       3.06     No multiple  royalties  shall be payable  because  any  Licensed
                Products or Licensed  Processes  are covered by more than one of
                the Licensed Patent Rights.

       3.07     In the event that Licensee elects to take a license under one or
                more patent rights of a third party in order to make, have made,
                use, or sell a Licensed  Product  within the  Licensed  Field of
                Use,  then Licensee  shall be entitled to reduce earned  royalty
                payments to  Licensor  under  Paragraph  3.03 by one half of the
                actual  amount  paid to such third  parties,  provided  that the
                royalty  payable to  Licensor  shall not be reduced to less than
                one half of the  amount  which  would  otherwise  be due in that
                calendar year.

       3.08     On sales of  Licensed  Products  by  Licensee  in other  than an
                arm's- length transaction, the value of the Net Sales attributed
                under this Article 3 to such a  transaction  shall be that which
                would have been received in an arm's-length  transaction,  based
                on sales of like  quantity and quality  products on or about the
                time of such  transaction.  The exclusive  license  hereunder is
                granted   to   Licensee   and   its   Affiliates.   Accordingly,
                inter-company  sales  among  them  will  not be  subject  to the
                imputed sales provision of this Paragraph.


4.     RECORD KEEPING

       4.01     Licensee agrees to keep accurate and correct records of Licensed
                Products made, used, or sold under this Agreement appropriate to
                determine  the amount of royalties  due  Licensor.  Such records
                shall be retained for at least [***] following a given reporting
                period. They shall be available during normal business hours for
                inspection  at the expense of Licensor by an accountant or other
                designated  auditor selected by Licensor for the sole purpose of
                verifying  reports and payments  hereunder.  The  accountant  or
                auditor shall only disclose to Licensor  information relating to
                the accuracy of reports and payments made under this  Agreement.
                If an inspection  shows an  underreporting  or  underpayment  in
                excess of five  percent  (5%) for any twelve (12) month  period,
                then  Licensee  shall  reimburse  Licensor  for the  cost of the
                inspection at the time Licensee pays the  unreported  royalties,
                including any late charges as required by Paragraph 5.06 of this
                Agreement.  All payments  required under this Paragraph shall be
                due  within  thirty  (30)  days of the  date  Licensor  provides
                Licensee notice of the payment due.


5.     REPORTS ON SALES AND PAYMENTS

       5.01     From the date of first commercial sale, Licensee shall submit to
                Licensor  within  sixty (60) days after  [***] a royalty  report
                setting forth for the  preceding  [***] period the amount of the
                Licensed  Products  sold by or on  behalf  of  Licensee  in each
                country within the Licensed  Territory,  the Net Sales,  and the
                amount of  royalty  accordingly  due.  With  each  such  royalty
                report,  Licensee shall submit  payment of the earned  royalties
                due.  If no  earned  royalties  are  due  to  Licensor  for  any
                reporting  period,  the written  report  shall be  certified  as
                correct by an authorized officer of Licensee and shall include a
                detailed  listing of all deductions made under Paragraph 1.06 to
                determine Net Sales made under Article 3 to determine  royalties
                due.

       5.02     Royalties  and all other  payments due under  Article 3 shall be
                paid in U.S. dollars, by wire transfer of funds to an account at
                a  commercial  bank in New  York  City or  Washington,  D.C.  as
                designated by the Licensor  Representative.  For conversion of a
                foreign currency to U.S.  Dollars,  the conversion rate shall be
                the rate quoted in the Wall  Street  Journal on the day that the
                payment is due (i.e., the last business day of the related [***]
                period).  Any loss of exchange,  value, taxes, or other expenses
                incurred in the transfer of conversion to U.S.  dollars shall be
                paid  entirely  by  Licensee.  The  royalty  report  required by
                Paragraph 5.01 of this  Agreement  shall be sent to the Licensor
                Representative,  at the  address for  notices  indicated  on the
                signature page hereof, concurrently with each such payment.


6.     PERFORMANCE

       6.01     Licensee shall use its reasonable  best efforts to introduce the
                Licensed   Products  into  the  commercial  market  as  soon  as
                practicable.


7.     INFRINGEMENT AND PATENT ENFORCEMENT

       7.01     Licensor  and  Licensee  agree to notify each other  promptly of
                each infringement or possible infringement, as well as any facts
                which may affect the validity,  scope, or  enforceability of the
                Licensed Patent Rights of which either Party becomes aware.

       7.02     If Licensor does not initiate legal action or otherwise abate an
                infringement  of the Licensed  Patent  Rights  within sixty (60)
                days of written notification to the Licensor Representative from
                Licensee  of  the  existence  of  a  substantial   infringement,
                Licensee  shall  have  the  right  (but not the  obligation)  to
                institute  infringement  litigation  against the  infringer.  If
                Licensee institutes such infringement  litigation within six (6)
                months,  Licensee  shall  be  entitled,  if  applicable,   to  a
                reduction in royalty rate as provided in Appendix B.

       7.03     In  the  event  that  a  declaratory  judgment  action  alleging
                invalidity of any of the Licensed Patent Rights shall be brought
                against  Licensor,  Licensor  agrees to notify  Licensee that an
                action alleging invalidity has been brought. Licensor represents
                that it will either commence legal action to defend against such
                a declaratory action alleging invalidity, or will allow Licensee
                to undertake such defense,  at its expense.  Licensee shall take
                no action to compel  Licensor  either to  initiate or to join in
                any such declaratory judgment action.  Should Licensor be made a
                party  to any  such  suit  by  motion  or any  other  action  of
                Licensee,  Licensee  shall  reimburse  Licensor  for any  costs,
                expenses,  or fees  which  Licensor  incurs  as a result  of its
                defending  against such motion or other action taken in response
                to the motion.


8.     NEGATION OF WARRANTIES AND INDEMNIFICATION

       8.01     Licensor  does not warrant the validity of the  Licensed  Patent
                Rights and makes no  representations  whatsoever  with regard to
                the scope of the Licensed  Patent  Rights,  or that the Licensed
                Patent Rights may be exploited without  infringing other patents
                or other intellectual property rights of third parties. However,
                Licensor  warrants that, as of the execution date hereof,  there
                are no patents or patent  applications  owned or  controlled  by
                Licensor,  other than those within the Licensed  Patent  Rights,
                which would  dominate the  manufacture,  use or sale of Licensed
                Products.

       8.02     LICENSOR   MAKE  NO   WARRANTIES,   EXPRESSED  OR  IMPLIED,   OR
                MERCHANTABILITY  OR  FITNESS  FOR A  PARTICULAR  PURPOSE  OF ANY
                SUBJECT  MATTER  DEFINED  BY THE CLAIMS OF THE  LICENSED  PATENT
                RIGHTS.

       8.03     Licensor does not represent  that it will commence legal actions
                against third parties infringing the Licensed Patent Rights.

       8.04     Licensee shall indemnify and hold Licensor,  its employees,  
                students, fellows,   agents  and  consultants  harmless  from 
                and  against  all liability,  demands, damages,  expenses, and 
                losses, including but not limited to death,  personal  injury, 
                illness,  or property  damage in connection with or arising out 
                of activities  performed  subsequent to the execution of the 
                Agreement directly related to a) the use by or on behalf of

       9.06     Within ninety (90) days of termination  of this Agreement  under
                this  Article 9 or  expiration  under  Paragraph  9.01,  a final
                report shall be submitted by Licensee.  Any royalty payments due
                to Licensor become  immediately due and payable upon termination

                either  party to  assert a right  hereunder  or to  insist  upon
                compliance  with any term or condition of this  Agreement  shall
                not  constitute a waiver of that right by such party or excuse a
                similar subsequent failure to perform any such term or condition
                by the other party.

       10.02    This  Agreement  constitutes  the entire  agreement  between the
                parties  relating to the subject  matter of the Licensed  Patent
                Rights, and all prior negotiations, representations, agreements,

                completely expressed by this Agreement.

       10.03    The provisions of this Agreement are severable, and in the event
                that any provision of this  Agreement  shall be determined to be
                invalid or unenforceable under any controlling body of law, such
                determination  shall  not in any  way  affect  the  validity  of
                enforceability of the remaining provisions of this Agreement.

       10.04    If either party desires a modification  to this  Agreement,  the

                modification  by the party  desiring the change,  confer in good
                faith to determine the  desirability  of such  modification.  No
                modification  will be  effective  until a written  amendment  is
                signed by the signatories to this Agreement or their designees.

       10.05    The  construction,  validity,  performance,  and  effect of this

                Representative,  in the  case of  notices  to  Licensor)  at the
                address  designated on the following  signature page, or to such
                other  address  as may be  designated  in  writing by such other
                party,  and shall be effective as of the date of the postmark of
                such notice.

       10.08    All Licensed  Products  manufactured  in, shipped to, or sold in

                preserve Licensor patent rights therein.

       10.09    By entering into this  Agreement,  Licensor does not directly or
                indirectly  endorse  any product or service  provided,  or to be
                provided,  by Licensee whether directly or indirectly related to
                this  Agreement.  Licensee  shall not  state or imply  that this
                Agreement is an endorsement by Licensor. Additionally,  Licensee
                shall  not  use  the  names  of  Licensor  in  any  advertising,
                promotional,  or sales  literature  without  the  prior  written
                consent of Licensor.

       10.10    The parties agree to attempt to settle  amicably any controversy
                or claim  arising  under  this  Agreement  or a  breach  of this
                Agreement.  In this  regard,  if a dispute  arises  between  the
                parties  relating to the  interpretation  or performance of this
                Agreement  or the  grounds  for  the  termination  thereof,  the
                parties agree to hold a meeting,  attended by  individuals  with
                decision-making  authority  regarding the dispute, to attempt in
                good faith to  negotiate a  resolution  of the dispute  prior to
                pursuing other available remedies. If, within 30 days after such
                meeting,  the  parties  have  not  succeeded  in  negotiating  a
                resolution  of the dispute,  such dispute  shall be submitted to
                non-binding   arbitration   under  the  then  current  Licensing
                Agreement   Arbitration   Rules  of  the  American   Arbitration
                Association  ("AAA"),  with a  panel  of  three  arbitrators  in
                Chicago,  IL.  Such  arbitrators  shall be  selected  by  mutual
                agreement of the parties or,  failing such  agreement,  shall be
                selected according to the aforesaid AAA rules. The parties shall
                bear the costs of arbitration  equally  unless the  arbitrators,
                pursuant to their right, but not their  obligation,  require the
                non-prevailing  party to bear all or any unequal  portion of the
                prevailing  party's costs. The arbitrators will be instructed to
                prepare and deliver a written, reasoned opinion conferring their
                decision. The rights and obligations of the parties to arbitrate
                any dispute  relating to the  interpretation  or  performance of
                this Agreement or the grounds for the termination  thereof shall
                survive the  expiration or termination of this Agreement for any
                reason.

       10.11    [***].

                This  Paragraph  10.11 does not apply to any license  agreements
                executed  by  Licensor  prior  to the  effective  date  of  this

                           of the Licensed  Product;  provided that,  other than

                           no event be less than 80% of Gross Sales.

                  (5)      In the case of  discounts on "bundles" of products or
                           services  which  include  Licensed  Products  or  the
                           Compound,  the selling  Party may, with notice to the
                           other Party,  calculate Net Sales by discounting  the
                           bona fide list price of such  product by the  average
                           percentage  discount  of all  products of the selling
                           party  and/or its  Affiliates  or  sublicensees  in a
                           particular "bundle", calculated as follows:

                           Average percentage
                           discount on a             = (1-A/B) x 100
                           particular "bundle"

                  where A equals  the  total  discounted  price of a  particular
                  "bundle" of products, and B equals the sum of the undiscounted
                  bona fide list  prices of each unit of every  product  in such
                  "bundle".  The  selling  party  shall  provide the other party
                  documentation,  reasonably  acceptable  to  the  other  party,
                  establishing  such  average  discount  with  respect  to  each
                  "bundle",  Net Sales shall be based on the  undiscounted  list
                  price  of  the  Licensed  Products  or  the  Compound  in  the
                  "bundle".  If a Licensed Product or the Compound in a "bundle"
                  is not sold  separately and no bona fide list price exists for
                  such  Licensed  Product or the  Compound,  the  Parties  shall
                  negotiate  in good  faith  an  imputed  list  price  for  such
                  Licensed  Product or the Compound,  and Net Sales with respect
                  thereto shall be based on such imputed list price.

                  establish the safety and efficacy of the Licensed  Product and
                  generate pharmacoeconomics date to support regulatory approval
                  in the proposed  therapeutic  indication as more fully defined

                  set forth on Exhibit 4.

         3.3      Neurocrine  shall provide to DOV, on a [***] basis  throughout

                  confidential any information  obtained during such examination
                  and shall report to DOV,  only the amounts of royalties  which
                  he or she  believes  to be due and payable  hereunder.  In the
                  event of a difference of opinion  between such  accountant and
                  Neurocrine  as to the  amount of  royalties  which are due and
                  payable,  the parties  hereto  shall use their best efforts to
                  resolve  such  differences.  If they  cannot do so, each party
                  will  appoint  one  additional  independent  certified  public
                  accountant,  and those two individuals will jointly appoint an
                  additional independent certified public accountant. A majority
                  decision of those three  accountants  will be conclusive as to
                  the  amount  of  royalties  which  are  due and  payable.  The
                  expenses of this dispute  resolution  procedure  will be borne
                  equally by Neurocrine and DOV.

                               Adverse Experiences

         7.1      During the term of this Agreement,  Neurocrine shall keep, and
                  shall cause its  sublicensees  to keep DOV  promptly and fully
                  informed of all pharmaceutical,  toxicological,  clinical, and
                  all  other   findings,   including   clinical  use,   studies,
                  investigations,   tests  and  prescription,  relating  to  any
                  adverse experiences with the Licensed Product.

<PAGE>


         7.2      Neurocrine  undertakes to notify DOV, as soon as possible,  of
                  any  serious  adverse  event as such  event is  defined by the
                  responsible  regulatory agency in the United States, Japan, or
                  within the EU, thought to be associated with clinical  studies
                  of, or the use or application of, the Licensed  Product.  Such
                  notification shall be made promptly but in no event later than
                  five (5) working days after  Neurocrine first learns of, or is
                  advised of, any adverse event described above.

         7.3      Neurocrine shall inform DOV without delay, of any governmental
                  action,  correspondence  or  reports  to or from  governmental
                  authorities  which may affect the continued  distribution  and
                  sale of the  Licensed  Product  and furnish DOV with copies of
                  any relevant documents relating thereto.

                               Patent Infringement

         8.1      In case any  actions,  claims,  demands,  suits or other legal
                  proceedings  are brought or threatened  to be brought  against
                  Neurocrine,  its Affiliates or sublicensees,  by a third party
                  for infringement of such third party's patent(s), by virtue of
                  Neurocrine's  manufacture,  use, sale or offer for sale of the
                  Licensed Product, Neurocrine shall notify DOV forthwith of the
                  threat or existence of such actions with  sufficient  evidence
                  thereof,  to enable the  parties  to  prepare  an  appropriate
                  defense strategy. The parties shall consult together as to the
                  action to be taken and as to how the defense  will be handled.
                  [***].

                  Neurocrine  undertakes  not to make any admission of liability
                  to  a  claimant  or   plaintiff  or  his,  her  or  its  legal
                  representative  or insurer  and not to sign any  agreement  in
                  respect of such proceedings  adversely affecting the rights of
                  DOV [***], which will not be unreasonably withheld.

                  If  Neurocrine,  because  of any  settlement  of  the  claimed
                  infringement or a final unappealable or non-appealed  judgment
                  of a court of  competent  jurisdiction,  is  required  to make
                  payments  to one or more  third  parties  to  obtain a license
                  without which the marketing of the Licensed  Product could not
                  be  made  in a  given  country,  Neurocrine  may  deduct  such
                  payments  from  the  royalty  payments  due to DOV  hereunder,
                  provided  however  that in no event shall the royalty  rate be
                  reduced by more than [***] of that which  would  otherwise  be
                  due to DOV.

         8.2      Neurocrine  shall promptly inform DOV of any suspected  patent
                  infringement  by a  third  party  and  provide  DOV  with  any
                  available evidence of such suspected infringement.

<PAGE>


                  DOV shall have the right but not the  obligation  to institute
                  any  claim,  suit or  proceeding  against  an  infringer  or a
                  presumed  infringer.  DOV shall control the prosecution of any
                  such suit, claim or proceeding, including, without limitation,
                  the choice of counsel and any  settlement  of any such suit or
                  claim.  Neurocrine  shall  provide  DOV  with  all  reasonable
                  assistance  (other than  financial)  required to institute and
                  maintain such proceedings.

                  Neurocrine  shall only have the right to institute  any claim,
                  suit  or  proceeding   against  an  infringer  or  a  presumed
                  infringer  in the event  that DOV elects not to do so. In such
                  event,  Neurocrine  shall control the  prosecution of any such
                  suit, claim or proceeding,  including, without limitation, the
                  choice  of  counsel  and any  settlement  of any such  suit or
                  claim.  DOV  shall  provide  Neurocrine  with  all  reasonable
                  assistance  (other than  financial)  required to institute and
                  maintain   such   proceedings.    During   such   proceedings,
                  Neurocrine's  royalty  obligations  to DOV shall be reduced to
                  the greater of [***] of the royalty payable  hereunder and the
                  royalty  rate that DOV owes to ACY at that time.  Any proceeds
                  from such  proceedings  shall first be  allocated to reimburse
                  Neurocrine  for its  costs  in  such  proceedings,  second  to
                  reimburse DOV for its lost royalty  revenue during such period
                  and the remainder to Neurocrine.  In the event that Neurocrine
                  is not successful in its suit, DOV shall not be reimbursed for
                  any lost royalty revenue.

                    Indemnification, Liability and Insurance

         9.1      Neurocrine, in the absence of negligence or willful misconduct
                  on the part of DOV, its Affiliates and  sublicensees and their
                  respective   employees,   agents,   officers,   directors  and

                  Agreement and thereafter,  indemnify,  defend and hold DOV and
                  its respective directors,  officers, partners,  employees, and
                  agents  harmless  from  and  against  any and all  claims  and
                  expenses, including, without limitation, legal expenses, court
                  costs,  and  reasonable  attorney's  fees,  arising  out of or
                  relating  to the death of or actual or  alleged  injury to any
                  person(s)  or damage  to third  party  property,  and from and
                  against  any other  third  party  claim,  proceeding,  demand,
                  expense,   cost  and   liability   of  any   kind   whatsoever
                  (collectively "liabilities") resulting from, arising out of or
                  related to product  liability  claims  involving  the Licensed
                  Product.

                  respective   employees,   agents,   officers,   directors  and
                  permitted  assigns  shall at all times during the term of this
                  Agreement   and   thereafter,   indemnify,   defend  and  hold
                  Neurocrine and its respective directors,  officers,  partners,
                  employees,  and agents  harmless  from and against any and all
                  claims  and  expenses  including,  without  limitation,  legal
                  expenses,  court costs and reasonable  attorney's fees arising
                  out of, or  relating  to,  the  death of or actual or  alleged
                  injury to any person(s) or damage to third party property, and
                  from and  against  any other  third-party  claim,  proceeding,
                  demand,  expense,  cost and  liability of any kind  whatsoever
                  resulting from,  arising out of, or related to DOV's breach of
                  Article 10.9 herein,  and any actions taken by DOV  pertaining
                  to the  Compound or Licensed  Product  prior to the  effective
                  date of this Agreement.

         9.3      Neurocrine  shall  maintain,   and  cause  any  sublicense  to
                  maintain,  a product  liability  insurance  program  which may
                  include  funded  self-insurance   reserves,   with  additional
                  coverage by a  nationally-recognized  insurance carrier,  with
                  respect  to  the  development,  manufacture  and  sale  of the
                  Licensed  Product.  Coverage  shall be in such  amounts as are
                  customary within the industry.  Neurocrine and any sublicensee
                  shall  maintain such  insurance  program for so long as it, or
                  any sublicensee, continues to develop, manufacture or sell the
                  Licensed  Product  and  thereafter  for so long as required to

         9.4      Neurocrine  (and  its  sublicensee)  will  name DOV and ACY as
                  additional   insureds  on  its  product  liability   insurance
                  policies.  Upon execution of this  Agreement,  Neurocrine will
                  supply DOV with evidence of such coverage, and Neurocrine will
                  inform  DOV,  during  the  term  of  this  Agreement,  of  any
                  modifications to such coverages.

                  be  terminated,  but only  suspended and the party so affected
                  shall continue to perform its obligations as soon as such case

         15.1     This Agreement shall continue in full force and effect in each
                  country  of  the  Territory  until  the  later  of  the  final
                  expiration  of a patent  covering the Compound or the Licensed
                  Product  in  such  country,  or a  period  of ten  (10)  years
                  following the first sale of Licensed  Product by Neurocrine or
                  its sublicensee in such country.

         15.2     Upon  expiration  of  this  Agreement,  with  respect  to each
                  country of the Territory, Neurocrine shall be deemed to have a
                  full-paid, royalty-free license with the right to make or have
                  made,  use or sell the Compound  and the  Licensed  Product as
                  well as to freely  utilize  all data  generated  hereunder  or
                  received from DOV by Neurocrine, without further obligation to
                  DOV,  except for  maintaining  confidentiality  as required by
                  Article 6 of this Agreement.

         15.3     In the event  that a party  hereto  shall be  presumed  by the
                  other  to  have   breached  any  material   condition   herein
                  contained,  the  complaining  party  shall  provide  a written
                  notice  of  such  presumed  breach,  requesting  rectification
                  within a thirty  (30) day  period  from the date of receipt of
                  such  notice.  The  party  presumed  to be in  breach  of  the
                  Agreement  shall either submit a commercially  reasonable plan
                  for  rectification  within 15  (fifteen)  days of  receipt  of
                  notice (if the breach  cannot be  rectified  within the thirty
                  (30) day  period),  or take  appropriate  steps to remedy  the
                  breach within such period.  If, within such thirty-day period,
                  neither the aforesaid plan shall have been submitted,  nor the
                  breach cured,  the party claiming  breach shall be entitled to
                  [***]written notice to the other party, [***].

         15.4     This  Agreement may be terminated  immediately by either party
                  by  giving  notice  to the  other  party if such  other  party
                  becomes  insolvent or has committed an act of bankruptcy or if
                  an order or  resolution  is made  for the  winding  up of such
                  other party.

                                  Miscellaneous

         16.1     This Agreement  constitutes the full understanding between the
                  parties  and  supersedes  any and all  prior  oral or  written
                  understandings  and  agreements  with  respect to the  subject
                  matter  hereof.  No  terms,   conditions,   understandings  or
                  Agreements  purporting to modify, amend or vary this Agreement
                  shall be  binding  unless  made in  writing  and signed by the
                  parties hereto.

         16.2     The invalidity or  unenforceability  of an Article or any part
                  of an Article of this Agreement in any jurisdiction  shall not
                  cause  the  invalidity  of the  entire  Agreement  as to  such
                  jurisdiction,   and  shall  not   affect   the   validity   or
                  enforceability  of such  Article or such part of an Article in
                  any other jurisdiction.  The parties shall replace any Article
                  or  part of an  Article  found  invalid  or  unenforceable  by
                  alternative  provisions  which shall be as similar as possible
                  in their conditions with regard to their spirit and commercial
                  effect.  If this Agreement in any  jurisdiction is found to be
                  invalid or  unenforceable,  the parties shall replace it by an
                  alternative agreement which shall be as similar as possible in
                  its  conditions  with  regard  to its  spirit  and  commercial
                  effect.

         16.3     No actual  waiver of breach or default by either  party hereto
                  of  any  provision  of  this  Agreement  shall  be  deemed  or
                  construed to be a waiver of any  succeeding  breach or default
                  of the same or any other provision of this Agreement.

         16.4     This Agreement shall not constitute  either party as the joint
                  venturer, legal representative or agent of the other party for
                  any purpose, whatsoever. Neither party shall have any right or
                  authority to assume or create any obligation or responsibility
                  for, or on behalf of, the other party,  or to  otherwise  bind
                  the other party.

         16.5     The parties recognize that this is a master agreement covering
                  a number of countries. If, for any country in the Territory it
                  becomes necessary to execute a separate instrument in order to
                  satisfy local requirements,  the parties agree to execute such
                  further  instrument,  which shall, to the extent  permitted by
                  the laws of the particular  country,  conform to the terms and
                  conditions of this Agreement.

         16.6     This Agreement has been  originally  written and signed in the
                  English  language.  If any translation into any other language
                  is required for purposes of governmental  filings, the parties
                  shall  arrange  for such  translation,  and the costs  thereof
                  shall be borne by the  party  legally  required  to make  such
                  filing.  In the event of any  question  or  dispute  as to the
                  meaning or interpretation of any term,  condition or provision
                  of this Agreement,  the English  language version shall in all
                  events govern for all purposes, whatsoever.

         16.7     Termination of this Agreement for any reason, or expiration of
                  this  Agreement,  will not affect  obligations,  including the
                  payment of any  Scheduled  Payments  or  royalties  which have
                  accrued  as of the  date of  termination  or  expiration,  and
                  rights  and  obligations   which,   are  intended  to  survive
                  termination or expiration of this Agreement.

         16.8     This  Agreement is executed  simultaneously  in  counterparts,
                  each of which  shall be deemed an  original,  but all of which
                  shall constitute but one and the same instrument.

         16.9     Neither party shall issue any press release or other publicity
                  materials, or make any oral or written presentation concerning
                  the  Compound  or  Licensed  Product  without the 15 day prior
                  consent of the other  party,  which  will not be  unreasonably
                  withheld.  This  restriction  shall not  apply to  disclosures
                  required by law or  regulation  within any country  within the
                  Territory.  However,  the parties shall  coordinate,  to every
                  extent possible, as to the wording of any such disclosure.

                                                                   Exhibit 10.4

Warrant Agreement dated June 30, 1998 between  Neurocrine  Biosciences,  Inc., a
Delaware corporation (the "Company"), and DOV Pharmaceutical, Inc., a New Jersey

                  Whereas  Holder  and the  Company  are  parties  to a  certain
Sublicense  and  Development  Agreement  dated  June 30,  1998 (the  "Sublicense
Agreement"); and
                  Whereas pursuant to the terms of the Sublicense Agreement, the
Company has agreed to issue Holder  certain  warrants to purchase  shares of the
Company's Common Stock (as defined in section 8.5), with no par value; and

                  Now therefore for good and valuable consideration, the receipt
of which is hereby acknowledged, the parties agree as follows:

                  1 Grant.  The Company grants Holder  warrants  ("Warrants") to
purchase up to [***] shares of Common Stock  ("Warrants")  at the Exercise Price
(as defined in section  2.1),  subject to  adjustment  as provided in Section 8,
during the period  commencing  on the start date of the [***] (as defined in the
Sublicense Agreement) and ending five years thereafter (the "Exercise Period").
                  2.       Exercise Price.

                  2.1  The  Exercise  Price  for (a)  [***]  warrants  shall  be

section 2.2) per share of the Common Stock on the date hereof, and for (b) [***]
warrants  shall be the Market Price of the Common Stock on the start date of the
[***].


<PAGE>

                  2.2 "Market  Price" shall be the mean of the closing  price of
the Common Stock as quoted on the National  Association  of Securities  Dealers,
Inc. Automated  Quotation System or such other national  securities  exchange or
over-the-counter  market on which the Common Stock is quoted; in the case of the
aforementioned [***] warrants for the 20-day period prior to the date hereof and
in the case of the aforementioned  [***] warrants for the 20-day period prior to
start of the [***].

                  3. Warrant  Certificates.  The warrant certificates  delivered
pursuant to this Warrant  Agreement  shall be in the form set forth in Exhibit A
with such appropriate  changes  required or permitted by this Warrant  Agreement
(the "Warrant Certificates").

                  4.       Exercise of Warrant.

                  4.1 Manner of Exercise.  The Warrants are  exercisable  during

the Company at its  executive  offices  located at 3050 Science  Park Road,  San
Diego, California 42121, attn: Chief Financial Officer (or such other officer as

set forth in  Exhibit B and  payment  of the  Exercise  Price,  Holder  shall be
entitled to receive a  certificate  for the shares of Common Stock so purchased.
The purchase rights  represented by each Warrant  Certificate are exercisable at
the  option of Holder in whole or in part,  but not as to  fractional  shares of
Common Stock.



<PAGE>


                  4.2  Non-Cash  Exercise.  In addition to the method of payment
set forth in  section  4.1 and in lieu of cash  payment,  Holder  shall have the
right to exercise  the Warrants in full or in part by  surrendering  the Warrant
Certificate in the manner specified in section 4.1 in exchange for the number of
shares of Common Stock equal to the product of (x) the number of shares  covered
by the Warrants are being exercised multiplied by (y) a fraction,  the numerator
of  which is the  closing  price of the  Company's  Common  Stock on the date of
exercise less the Exercise  Price,  and the denominator of which is such closing
price.


                  5.       Issuance of Certificates.

                  5.1  Prompt  Issuance.  Upon  exercise  of the  Warrants,  the
certificates  for the shares of Common Stock  underlying  such Warrants shall be
issued within ten business days without charge to the Holder including,  without
limitation,  any tax that may be payable in connection  with the  issuance,  and
such  certificates  shall be  issued  in the name of,  or in such name as may be
directed by, Holder,  provided that the Company shall not be required to pay any
tax payable  solely due to the issuance of a  certificates  in a name other than
Holder.  The Company shall not be required to issue or deliver such certificates
until  Holder pays the amount of such tax to the Company or  establishes  to the
satisfaction of the Company that such tax has been paid.
                  5.2 Execution of Certificates.  Stock certificates issued upon
exercise  of the  Warrants  shall be  executed  by  authorized  officers  of the
Company.  The person in whose name any such stock  certificate  is issued shall,
for all  purposes,  be deemed to have become the holder of record of such shares
on the date of exercise of the Warrant.

                  5.3 New Warrant Certificate. If Holder purchases less than all
the  shares of Common  Stock  purchasable  under any  Warrant  Certificate,  the
Company  shall cancel the Warrant  Certificate  upon the  surrender  thereof and
shall  execute  and  deliver a new  Warrant  Certificate  of like  tenor for the
balance of the shares of Common Stock not so purchased.

                  6. Transfer of Warrants. Subject to the restrictions set forth
in section 7, Holder may sell, assign, pledge, hypothecate or otherwise transfer

                  7.       Registration.

                  7.1 Registration Under the Securities Act of 1933. Neither the
Warrants nor the shares of Common Stock  issuable  upon exercise of the Warrants
have  been  registered  under  the  Securities  Act of  1933,  as  amended  (the
"Securities  Act"),  or any applicable  state  securities or blue sky laws. Upon
exercise of the Warrants,  the Company may cause a legend in  substantially  the
form set forth below to be placed on each certificate representing the shares of
Common Stock issued.

                  The securities  represented by this  certificate have not been
                  registered for public resale under the Securities Act of 1933,
                  as  amended  ("Securities  Act"),  and  may  not  be  offered,
                  transferred  or  sold  except  pursuant  to (i)  an  effective
                  registration  statement  under  the  Securities  Act  and  any
                  applicable  state  securities or blue sky laws,  (ii) Rule 144
                  under  the  Securities  Act (or any  similar  rule  under  the
                  Securities Act relating to the disposition of securities),  to
                  the extent applicable,  together with an opinion of counsel if
                  such opinion,  reasonably satisfactory to issuer's counsel, is
                  that  such  transfer  is  permitted  or  (iii) an  opinion  of
                  counsel, if such opinion,  reasonably satisfactory to issuer's
                  counsel,  is that an  exemption  from  registration  under the
                  Securities Act and any applicable state securities or blue sky
                  laws is available.

                  7.2 Registration  Rights.  Holder shall have such registration
rights set forth in that certain New  Registration  Rights Agreement dated March
29, 1996.
                  8.       Adjustments to Exercise and Number of Securities.


<PAGE>



                  8.1   Recapitalization  and   Reclassifications.   If  upon  a
recapitalization or reclassification the shares of Common Stock shall be changed
into or become  exchangeable for a larger or smaller number of shares, then upon
the  effective  date  thereof  the number of shares of Common  Stock that Holder
shall be entitled to purchase upon exercise of the Warrant shall be increased or
decreased,  as the case may be, in direct proportion to the increase or decrease
in the number of shares of Common  Stock by reason of such  recapitalization  or
reclassification, and the Exercise Price shall be, in the case of an increase in
the number of shares,  proportionately  decreased and, in the case of a decrease
in the number of shares, proportionately increased.

                  8.2  Sale;  Merger;   Consolidation.   Subject  to  the  prior
notification  requirements  of section  13,  upon a  transfer  or sale of all or
substantially  all the assets of the Company or in the case of any consolidation
or merger of the Company  with another  entity  (other than a  consolidation  or
merger that does not result in any reclassification or change of the outstanding
Common  Stock),  the  transferee,  purchaser or entity  formed by or surviving a
consolidation or merger, as the case may be, shall execute and deliver to Holder
a  supplemental  warrant  agreement  giving Holder the right during the Exercise
Period to receive,  upon exercise of a Warrant, the kind and amount of shares of
stock and/or other securities receivable upon such transfer, sale, consolidation
or  merger,  as the case may be, by a holder  of the  number of shares of Common
Stock for which such Warrant might have been exercised immediately prior to such
transfer,  sale,  consolidation or merger; provided that if such transfer, sale,
consolidation  or  merger  shall  result  in the  shareholders  of  the  Company
receiving cash or publicly traded  securities having a value per share in excess
of the Exercise Price,  this Warrant  Agreement shall terminate if not exercised
prior  to the  closing  date  of such  transaction.  Such  supplemental  warrant
agreement  shall  provide  for  adjustments  that  shall  be  identical  to  the
adjustments provided in this section 8.


<PAGE>



                  8.3 Dividends and Other Distributions. If the Company declares
a dividend  payable  in shares of Common  Stock,  Holder  shall be  entitled  to
receive  upon  exercise of the  Warrant,  in addition to the number of shares of
Common Stock as to which the Warrant is  exercised,  such  additional  shares of
Common  Stock as Holder  would have  received  had the  Warrant  been  exercised
immediately prior to such record date for the dividend.  If the Company declares
a dividend of  securities  other than a dividend of Common  Stock,  Holder shall
thereafter  be entitled to  receive,  in addition to the shares of Common  Stock
receivable upon the exercise of such Warrants, such non-Common Stock dividend as
Holder would have received had the Warrant been exercised  immediately  prior to
such  record  date  for the  dividend.  At the  time  of any  such  dividend  or
distribution,  the Company shall make appropriate  reserves to ensure the timely
performance  of the  provisions  of this section 8.3. If the Company  declares a
cash dividend the Holder shall not be entitled to receive any such dividend.

                  8.4      Definition of Common Stock.  For the purpose of this
 Agreement, the term Common Stock
shall mean the following:
                           (a)      the class of stock designated as Common 
Stock in the Articles of Incorporation of the Company as may be amended, or any 
other class of stock resulting from successive changes or reclassifications of 
such Common Stock; and
                           (b) if, as a result of an adjustment made pursuant to
section 8, Holder shall upon
exercise of the Warrants become entitled to receive securities other than Common
Stock,  wherever  appropriate,  all references  herein to shares of Common Stock
shall be deemed to refer to and include such other securities and thereafter the
number of such other securities shall be subject to adjustment from time to time
in a manner and upon terms as nearly equivalent as practicable to the provisions
of this section 8.

                  9.  Issuance of New Warrant  Certificate.  Upon receipt by the
Company of evidence reasonably satisfactory to it of a loss, theft,  destruction
or mutilation of a Warrant  Certificate,  reimbursement by Holder to the Company
of all  incidental  expenses  and,  in the case of loss,  theft or  destruction,
receipt of indemnity or security from Holder reasonably  satisfactory to it, or,
in the case of a mutilated Warrant Certificate,  upon surrender and cancellation
thereof the Company shall make and deliver a replacement  Warrant Certificate to
Holder.

                  10. Elimination of Fractional Interests. The Company shall not
be required to issue  certificates  representing  fractions  of shares of Common
Stock upon the exercise of the  Warrants.  The Company  shall have the option to
make  payment  in cash in  respect  of any  fractional  shares  or to round  any
fraction up to the nearest whole number of shares of Common Stock.

                  11.  Reservation and Listing of Securities.  The Company shall
at all times reserve and keep available out of its  authorized  shares of Common
Stock,  solely for the purpose of issuance  upon the  exercise of the  Warrants,
such  number of shares of Common  Stock as shall be issuable  upon the  exercise
thereof.  The Company  covenants and agrees that,  upon exercise of the Warrants
and payment of the Exercise Price by Holder, all shares of Common Stock issuable
upon such exercise shall be duly and validly issued, fully paid,  non-assessable
and not subject to the preemptive  rights of any stockholder.  The Company shall
use its best  efforts  to cause all  shares of Common  Stock  issuable  upon the
exercise of the Warrants to be listed  (subject to official  notice of issuance)
on all  securities  exchanges,  if any,  on which the  Common  Stock may then be
listed and/or quoted.

                  12.   Representations   and   Warranties  of  Holder.   Holder
represents  and warrants to the Company  that the  Warrants  are being  acquired
solely for Holder's own account, for investment,  and not with a view to resale,
distribution,  assignment,  subdivision or fractionalization thereof, and Holder
has no  present  plans to enter into any  contract,  undertaking,  agreement  or
arrangement for such purpose.


<PAGE>



                  13.  Notice  to  Warrant  Holder.  Nothing  contained  in this
Warrant  Agreement  shall be construed as conferring  upon Holder,  by virtue of
holding  the  Warrants,  the  right to vote,  consent  or  receive  notice  as a
stockholder  in respect of any  meetings  of  stockholders  for the  election of
directors or any other matter,  or as having any rights as a stockholder  of the
Company.  If,  however,  at any time prior to the expiration of the Warrants and
their exercise, any of the following events shall occur:

                  (a) the  Company  shall  take a record of the  holders  of its
shares of Common Stock for the purpose of  entitling  them to receive a dividend
or  distribution  payable  otherwise  than  in  cash,  or  a  cash  dividend  or
distribution  payable  otherwise  than out of current or retained  earnings,  as
indicated by the accounting  treatment  (which  treatment shall be in accordance
with generally accepted accounting  principles) of such dividend or distribution
on the books of the Company; or

                  (b) the  Company  shall offer to all the holders of its Common
Stock any  additional  shares of  capital  stock of the  Company  or  securities
convertible into or exchange for shares of capital stock of the Company,  or any
option, right or warrant to subscribe therefor; or

                  (c)  a  dissolution,   liquidation,   winding  up,   transfer,
consolidation, merger or a sale of all or substantially all its property, assets
and business as an entirety shall be proposed;


<PAGE>


the  Company  shall give notice of such event at least 15 days prior to the date
fixed as a record  date or the date of the closing  the  transfer  books for the
determination  of the  stockholders  entitled  to such  dividend,  distribution,
convertible or exchangeable  securities or subscription  rights,  or entitled to
vote on such proposed dissolution,  liquidation, winding up or sale. Such notice
shall specify such record date or the date of closing the transfer books, as the
case may be.  Failure to give such notice or any defect therein shall not affect
the validity of any action taken in connection  with the  declaration or payment
of any  such  dividend,  or the  issuance  of any  convertible  or  exchangeable
securities,  or  subscription  rights,  options  or  warrants,  or any  proposed
dissolution, liquidation, winding up or sale.

                  14.  Notices.  Any notice or demand  pursuant to this  Warrant
Agreement shall be in writing and shall be deemed sufficiently given or made (a)
upon personal delivery;  (b) the day following delivery to a reputable overnight
courier or (c) three days  following  mailing by certified or  registered  mail,
return receipt requested,  postage prepaid, and addressed, until the other party
is notified of another address, as follows:

                                                                    Exhibit 10.5

                  Warrant  Agreement  dated  June 30,  1998  between  Neurocrine
Biosciences,  Inc.,  a  Delaware  corporation  (the  "Company"),  and Jeff Eliot
Margolis ("Holder").

                  Whereas  Holder  and the  Company  are  parties  to a  certain
Sublicense  and  Development  Agreement  dated  June 30,  1998 (the  "Sublicense
Agreement"); and

                  Whereas pursuant to the terms of the Sublicense Agreement, the
Company has agreed to issue Holder  certain  warrants to purchase  shares of the
Company's Common Stock (as defined in section 8.5), with no par value; and

                  Now therefore for good and valuable consideration, the receipt
of which is hereby acknowledged, the parties agree as follows:

                  1 Grant.  The Company grants Holder  warrants  ("Warrants") to
purchase up to [***] shares of Common Stock  ("Warrants")  at the Exercise Price
(as defined in section  2.1),  subject to  adjustment  as provided in Section 8,
during the period  commencing  on the start date of the [***] (as defined in the
Sublicense Agreement) and ending five years thereafter (the "Exercise Period").

                  2.       Exercise Price.

                  2.1  The  Exercise  Price  for (a)  [***]  warrants  shall  be
$8.040625 per share of Common Stock representing the Market Price (as defined in
section 2.2) per share of the Common Stock on the date hereof, and for (b) [***]
warrants  shall be the Market Price of the Common Stock on the start date of the
[***].


<PAGE>

                  2.2 "Market  Price" shall be the mean of the closing  price of
the Common Stock as quoted on the National  Association  of Securities  Dealers,
Inc. Automated  Quotation System or such other national  securities  exchange or
over-the-counter  market on which the Common Stock is quoted; in the case of the
aforementioned [***] warrants for the 20-day period prior to the date hereof and
in the case of the aforementioned  [***] warrants for the 20-day period prior to
start of the [***].

                  3. Warrant  Certificates.  The warrant certificates  delivered
pursuant to this Warrant  Agreement  shall be in the form set forth in Exhibit A
with such appropriate  changes  required or permitted by this Warrant  Agreement
(the "Warrant Certificates").

                  4.       Exercise of Warrant.

                  4.1 Manner of Exercise.  The Warrants are  exercisable  during
the Exercise  Period (but not  thereafter)  at the Exercise Price and payable to
the Company at its  executive  offices  located at 3050 Science  Park Road,  San
Diego, California 42121, attn: Chief Financial Officer (or such other officer as
designated  to Holder by the Company by notice),  by certified or official  bank
check in New York Clearing  House funds or wire  transfer.  Upon  surrender of a
Warrant Certificate,  submission of an executed election to purchase in the form
set forth in  Exhibit B and  payment  of the  Exercise  Price,  Holder  shall be
entitled to receive a  certificate  for the shares of Common Stock so purchased.
The purchase rights  represented by each Warrant  Certificate are exercisable at
the  option of Holder in whole or in part,  but not as to  fractional  shares of
Common Stock.

                  4.2  Non-Cash  Exercise.  In addition to the method of payment
set forth in  section  4.1 and in lieu of cash  payment,  Holder  shall have the
right to exercise  the Warrants in full or in part by  surrendering  the Warrant
Certificate in the manner specified in section 4.1 in exchange for the number of
shares of Common Stock equal to the product of (x) the number of shares  covered
by the Warrants are being exercised multiplied by (y) a fraction,  the numerator
of  which is the  closing  price of the  Company's  Common  Stock on the date of
exercise less the Exercise  Price,  and the denominator of which is such closing
price.


<PAGE>

                  5.       Issuance of Certificates.

                  5.1  Prompt  Issuance.  Upon  exercise  of the  Warrants,  the
certificates  for the shares of Common Stock  underlying  such Warrants shall be
issued within ten business days without charge to the Holder including,  without
limitation,  any tax that may be payable in connection  with the  issuance,  and
such  certificates  shall be  issued  in the name of,  or in such name as may be
directed by, Holder,  provided that the Company shall not be required to pay any
tax payable  solely due to the issuance of a  certificates  in a name other than
Holder.  The Company shall not be required to issue or deliver such certificates
until  Holder pays the amount of such tax to the Company or  establishes  to the
satisfaction of the Company that such tax has been paid.

                  5.2 Execution of Certificates.  Stock certificates issued upon
exercise  of the  Warrants  shall be  executed  by  authorized  officers  of the
Company.  The person in whose name any such stock  certificate  is issued shall,
for all  purposes,  be deemed to have become the holder of record of such shares
on the date of exercise of the Warrant.

                  5.3 New Warrant Certificate. If Holder purchases less than all
the  shares of Common  Stock  purchasable  under any  Warrant  Certificate,  the
Company  shall cancel the Warrant  Certificate  upon the  surrender  thereof and
shall  execute  and  deliver a new  Warrant  Certificate  of like  tenor for the
balance of the shares of Common Stock not so purchased.

                  6. Transfer of Warrants. Subject to the restrictions set forth
in section 7, Holder may sell, assign, pledge, hypothecate or otherwise transfer
any rights under this Warrant Agreement,  following notice to the Company in the

<PAGE>

                  7. Registration Under the Securities Act of 1933 .

                  7.1  Neither  the  Warrants  nor the  shares of  Common  Stock
issuable upon exercise of the Warrants have been registered under the Securities
Act of  1933,  as  amended  (the  "Securities  Act"),  or any  applicable  state
securities  or blue sky laws.  Upon  exercise of the  Warrants,  the Company may
cause a legend in  substantially  the form set forth  below to be placed on each
certificate representing the shares of Common Stock issued.

                  The securities  represented by this  certificate have not been
                  registered for public resale under the Securities Act of 1933,
                  as  amended  ("Securities  Act"),  and  may  not  be  offered,
                  transferred  or  sold  except  pursuant  to (i)  an  effective
                  registration  statement  under  the  Securities  Act  and  any
                  applicable  state  securities or blue sky laws,  (ii) Rule 144
                  under  the  Securities  Act (or any  similar  rule  under  the
                  Securities Act relating to the disposition of securities),  to
                  the extent applicable,  together with an opinion of counsel if
                  such opinion,  reasonably satisfactory to issuer's counsel, is
                  that  such  transfer  is  permitted  or  (iii) an  opinion  of
                  counsel, if such opinion,  reasonably satisfactory to issuer's
                  counsel,  is that an  exemption  from  registration  under the
                  Securities Act and any applicable state securities or blue sky
                  laws is available.

                  7.2 Holder  shall have such  registration  rights set forth in
that certain New Registration Rights Agreement dated March 29, 1996.

                  8.       Adjustments to Exercise and Number of Securities.


<PAGE>



                  8.1   Recapitalization  and   Reclassifications.   If  upon  a
recapitalization or reclassification the shares of Common Stock shall be changed
into or become  exchangeable for a larger or smaller number of shares, then upon
the  effective  date  thereof  the number of shares of Common  Stock that Holder
shall be entitled to purchase upon exercise of the Warrant shall be increased or
decreased,  as the case may be, in direct proportion to the increase or decrease
in the number of shares of Common  Stock by reason of such  recapitalization  or
reclassification, and the Exercise Price shall be, in the case of an increase in
the number of shares,  proportionately  decreased and, in the case of a decrease
in the number of shares, proportionately increased.

                  8.2  Sale;  Merger;   Consolidation.   Subject  to  the  prior
notification  requirements  of section  13,  upon a  transfer  or sale of all or
substantially  all the assets of the Company or in the case of any consolidation
or merger of the Company  with another  entity  (other than a  consolidation  or
merger that does not result in any reclassification or change of the outstanding
Common  Stock),  the  transferee,  purchaser or entity  formed by or surviving a
consolidation or merger, as the case may be, shall execute and deliver to Holder
a  supplemental  warrant  agreement  giving Holder the right during the Exercise
Period to receive,  upon exercise of a Warrant, the kind and amount of shares of
stock and/or other securities receivable upon such transfer, sale, consolidation
or  merger,  as the case may be, by a holder  of the  number of shares of Common
Stock for which such Warrant might have been exercised immediately prior to such
transfer,  sale,  consolidation or merger, provided that if such transfer, sale,
consolidation  or  merger  shall  result  in the  shareholders  of  the  Company
receiving cash or publicly traded  securities having a value per share in excess
of the Exercise Price,  this Warrant  Agreement shall terminate if not exercised
prior  to the  closing  date  of such  transaction.  Such  supplemental  warrant
agreement  shall  provide  for  adjustments  that  shall  be  identical  to  the
adjustments provided in this section 8.


<PAGE>



                  8.3 Dividends and Other Distributions. If the Company declares
a dividend  payable  in shares of Common  Stock,  Holder  shall be  entitled  to
receive  upon  exercise of the  Warrant,  in addition to the number of shares of
Common Stock as to which the Warrant is  exercised,  such  additional  shares of
Common  Stock as Holder  would have  received  had the  Warrant  been  exercised
immediately prior to such record date for the dividend.  If the Company declares
a dividend of  securities  other than a dividend of Common  Stock,  Holder shall
thereafter  be entitled to  receive,  in addition to the shares of Common  Stock
receivable upon the exercise of such Warrants, such non-Common Stock dividend as
Holder would have received had the Warrant been exercised  immediately  prior to
such  record  date  for the  dividend.  At the  time  of any  such  dividend  or
distribution,  the Company shall make appropriate  reserves to ensure the timely
performance  of the  provisions  of this section 8.3. If the Company  declares a
cash dividend the Holder shall not be entitled to receive any such dividend.

                  8.4      Definition of Common  Stock.  For the purpose of this
Agreement,  the term Common Stock shall mean the following:

                           (a)      the class of stock  designated as Common 
Stock in the Articles of Incorporation of the Company as may be amended,  or any
other class of stock resulting from successive changes or  reclassifications  of
such Common Stock; and
                           (b) if, as a result of an adjustment made pursuant to
section 8, Holder shall upon exercise of the Warrants become entitled to receive
securities other than Common Stock, wherever appropriate,  all references herein
to shares of Common  Stock  shall be deemed to refer to and  include  such other
securities and thereafter the number of such other  securities  shall be subject
to adjustment from time to time in a manner and upon terms as nearly  equivalent
as practicable to the provisions of this section 8.


<PAGE>

                  9.  Issuance of New Warrant  Certificate.  Upon receipt by the
Company of evidence reasonably satisfactory to it of a loss, theft,  destruction
or mutilation of a Warrant  Certificate,  reimbursement by Holder to the Company
of all  incidental  expenses  and,  in the case of loss,  theft or  destruction,
receipt of indemnity or security from Holder reasonably  satisfactory to it, or,
in the case of a mutilated Warrant Certificate,  upon surrender and cancellation
thereof the Company shall make and deliver a replacement  Warrant Certificate to
Holder.

                  10. Elimination of Fractional Interests. The Company shall not
be required to issue  certificates  representing  fractions  of shares of Common
Stock upon the exercise of the  Warrants.  The Company  shall have the option to
make  payment  in cash in  respect  of any  fractional  shares  or to round  any
fraction up to the nearest whole number of shares of Common Stock.

                  11.  Reservation and Listing of Securities.  The Company shall
at all times reserve and keep available out of its  authorized  shares of Common
Stock,  solely for the purpose of issuance  upon the  exercise of the  Warrants,
such  number of shares of Common  Stock as shall be issuable  upon the  exercise
thereof.  The Company  covenants and agrees that,  upon exercise of the Warrants
and payment of the Exercise Price by Holder, all shares of Common Stock issuable
upon such exercise shall be duly and validly issued, fully paid,  non-assessable
and not subject to the preemptive  rights of any stockholder.  The Company shall
use its best  efforts  to cause all  shares of Common  Stock  issuable  upon the
exercise of the Warrants to be listed  (subject to official  notice of issuance)
on all  securities  exchanges,  if any,  on which the  Common  Stock may then be
listed and/or quoted.

                  12.   Representations   and   Warranties  of  Holder.   Holder
represents  and warrants to the Company that it is an  accredited  investor,  as
defined in Section 501 of Regulations under the Securities Act, the Warrants are
being acquired solely for Holder's own account,  for investment,  and not with a
view to  resale,  distribution,  assignment,  subdivision  or  fractionalization
thereof,   and  Holder  has  no  present  plans  to  enter  into  any  contract,
undertaking, agreement or arrangement for such purpose.


<PAGE>

                  13.  Notice  to  Warrant  Holder.  Nothing  contained  in this
Warrant  Agreement  shall be construed as conferring  upon Holder,  by virtue of
holding  the  Warrants,  the  right to vote,  consent  or  receive  notice  as a
stockholder  in respect of any  meetings  of  stockholders  for the  election of
directors or any other matter,  or as having any rights as a stockholder  of the
Company.  If,  however,  at any time prior to the expiration of the Warrants and
their exercise, any of the following events shall occur:

                  (a) the  Company  shall  take a record of the  holders  of its

                  Warrant  Agreement  dated  June 30,  1998  between  Neurocrine
Biosciences,  Inc., a Delaware corporation (the "Company"),  and Stephen L. Ross
("Holder").

                  Whereas  Holder  and the  Company  are  parties  to a  certain
Sublicense  and  Development  Agreement  dated  June 30,  1998 (the  "Sublicense
Agreement"); and

                  Whereas pursuant to the terms of the Sublicense Agreement, the
Company has agreed to issue Holder  certain  warrants to purchase  shares of the
Company's Common Stock (as defined in section 8.5), with no par value; and

                  Now therefore for good and valuable consideration, the receipt
of which is hereby acknowledged, the parties agree as follows:

                  1 Grant.  The Company grants Holder  warrants  ("Warrants") to
purchase up to [***] shares of Common Stock  ("Warrants")  at the Exercise Price
(as defined in section  2.1),  subject to  adjustment  as provided in Section 8,
during the period  commencing  on the start date of the [***] (as defined in the
Sublicense Agreement) and ending five years thereafter (the "Exercise Period").

                  2.       Exercise Price.

                  2.1  The  Exercise  Price  for (a)  [***]  warrants  shall  be
$8.040625 per share of Common Stock representing the Market Price (as defined in
section 2.2) per share of the Common Stock on the date hereof, and for (b) [***]
warrants  shall be the Market Price of the Common Stock on the start date of the
[***].


<PAGE>


                  2.2 "Market  Price" shall be the mean of the closing  price of
the Common Stock as quoted on the National  Association  of Securities  Dealers,
Inc. Automated  Quotation System or such other national  securities  exchange or
over-the-counter  market on which the Common Stock is quoted; in the case of the
aforementioned [***] warrants for the 20-day period prior to the date hereof and
in the case of the aforementioned  [***] warrants for the 20-day period prior to
start of the [***].

                  3. Warrant  Certificates.  The warrant certificates  delivered
pursuant to this Warrant  Agreement  shall be in the form set forth in Exhibit A
with such appropriate  changes  required or permitted by this Warrant  Agreement
(the "Warrant Certificates").

                  4.       Exercise of Warrant.

                  4.1 Manner of Exercise.  The Warrants are  exercisable  during
the Exercise  Period (but not  thereafter)  at the Exercise Price and payable to
the Company at its  executive  offices  located at 3050 Science  Park Road,  San
Diego, California 42121, attn: Chief Financial Officer (or such other officer as
designated  to Holder by the Company by notice),  by certified or official  bank
check in New York Clearing  House funds or wire  transfer.  Upon  surrender of a
Warrant Certificate,  submission of an executed election to purchase in the form
set forth in  Exhibit B and  payment  of the  Exercise  Price,  Holder  shall be
entitled to receive a  certificate  for the shares of Common Stock so purchased.
The purchase rights  represented by each Warrant  Certificate are exercisable at
the  option of Holder in whole or in part,  but not as to  fractional  shares of
Common Stock.

                  4.2  Non-Cash  Exercise.  In addition to the method of payment
set forth in  section  4.1 and in lieu of cash  payment,  Holder  shall have the
right to exercise  the Warrants in full or in part by  surrendering  the Warrant
Certificate in the manner specified in section 4.1 in exchange for the number of
shares of Common Stock equal to the product of (x) the number of shares  covered
by the Warrants are being exercised multiplied by (y) a fraction,  the numerator
of  which is the  closing  price of the  Company's  Common  Stock on the date of
exercise less the Exercise  Price,  and the denominator of which is such closing
price.

                  5.       Issuance of Certificates.

                  5.1  Prompt  Issuance.  Upon  exercise  of the  Warrants,  the
certificates  for the shares of Common Stock  underlying  such Warrants shall be
issued within ten business days without charge to the Holder including,  without
limitation,  any tax that may be payable in connection  with the  issuance,  and
such  certificates  shall be  issued  in the name of,  or in such name as may be
directed by, Holder,  provided that the Company shall not be required to pay any
tax payable  solely due to the issuance of a  certificates  in a name other than
Holder.  The Company shall not be required to issue or deliver such certificates
until  Holder pays the amount of such tax to the Company or  establishes  to the
satisfaction of the Company that such tax has been paid.

                  5.2 Execution of Certificates.  Stock certificates issued upon
exercise  of the  Warrants  shall be  executed  by  authorized  officers  of the
Company.  The person in whose name any such stock  certificate  is issued shall,
for all  purposes,  be deemed to have become the holder of record of such shares
on the date of exercise of the Warrant.

                  5.3 New Warrant Certificate. If Holder purchases less than all
the  shares of Common  Stock  purchasable  under any  Warrant  Certificate,  the
Company  shall cancel the Warrant  Certificate  upon the  surrender  thereof and
shall  execute  and  deliver a new  Warrant  Certificate  of like  tenor for the
balance of the shares of Common Stock not so purchased.

                  6. Transfer of Warrants. Subject to the restrictions set forth
in section 7, Holder may sell, assign, pledge, hypothecate or otherwise transfer

                  7. Registration Under the Securities Act of 1933 .

                  7.1  Neither  the  Warrants  nor the  shares of  Common  Stock
issuable upon exercise of the Warrants have been registered under the Securities
Act of  1933,  as  amended  (the  "Securities  Act"),  or any  applicable  state
securities  or blue sky laws.  Upon  exercise of the  Warrants,  the Company may
cause a legend in  substantially  the form set forth  below to be placed on each
certificate representing the shares of Common Stock issued.

                  The securities  represented by this  certificate have not been
                  registered for public resale under the Securities Act of 1933,
                  as  amended  ("Securities  Act"),  and  may  not  be  offered,
                  transferred  or  sold  except  pursuant  to (i)  an  effective
                  registration  statement  under  the  Securities  Act  and  any
                  applicable  state  securities or blue sky laws,  (ii) Rule 144
                  under  the  Securities  Act (or any  similar  rule  under  the
                  Securities Act relating to the disposition of securities),  to
                  the extent applicable,  together with an opinion of counsel if
                  such opinion,  reasonably satisfactory to issuer's counsel, is
                  that  such  transfer  is  permitted  or  (iii) an  opinion  of
                  counsel, if such opinion,  reasonably satisfactory to issuer's
                  counsel,  is that an  exemption  from  registration  under the
                  Securities Act and any applicable state securities or blue sky
                  laws is available.

                  7.2 Holder  shall have such  registration  rights set forth in
that certain New Registration Rights Agreement dated March 29, 1996.

                  8.       Adjustments to Exercise and Number of Securities.


<PAGE>



                  8.1   Recapitalization  and   Reclassifications.   If  upon  a
recapitalization or reclassification the shares of Common Stock shall be changed
into or become  exchangeable for a larger or smaller number of shares, then upon
the  effective  date  thereof  the number of shares of Common  Stock that Holder
shall be entitled to purchase upon exercise of the Warrant shall be increased or
decreased,  as the case may be, in direct proportion to the increase or decrease
in the number of shares of Common  Stock by reason of such  recapitalization  or
reclassification, and the Exercise Price shall be, in the case of an increase in
the number of shares,  proportionately  decreased and, in the case of a decrease
in the number of shares, proportionately increased.

                  8.2  Sale;  Merger;   Consolidation.   Subject  to  the  prior
notification  requirements  of section  13,  upon a  transfer  or sale of all or
substantially  all the assets of the Company or in the case of any consolidation
or merger of the Company  with another  entity  (other than a  consolidation  or
merger that does not result in any reclassification or change of the outstanding
Common  Stock),  the  transferee,  purchaser or entity  formed by or surviving a
consolidation or merger, as the case may be, shall execute and deliver to Holder
a  supplemental  warrant  agreement  giving Holder the right during the Exercise
Period to receive,  upon exercise of a Warrant, the kind and amount of shares of
stock and/or other securities receivable upon such transfer, sale, consolidation
or  merger,  as the case may be, by a holder  of the  number of shares of Common
Stock for which such Warrant might have been exercised immediately prior to such
transfer,  sale,  consolidation or merger, provided that if such transfer, sale,
consolidation  or  merger  shall  result  in the  shareholders  of  the  Company
receiving cash or publicly traded  securities having a value per share in excess
of the Exercise Price,  this Warrant  Agreement shall terminate if not exercised
prior  to the  closing  date  of such  transaction.  Such  supplemental  warrant
agreement  shall  provide  for  adjustments  that  shall  be  identical  to  the
adjustments provided in this section 8.


<PAGE>



                  8.3 Dividends and Other Distributions. If the Company declares
a dividend  payable  in shares of Common  Stock,  Holder  shall be  entitled  to
receive  upon  exercise of the  Warrant,  in addition to the number of shares of
Common Stock as to which the Warrant is  exercised,  such  additional  shares of
Common  Stock as Holder  would have  received  had the  Warrant  been  exercised
immediately prior to such record date for the dividend.  If the Company declares
a dividend of  securities  other than a dividend of Common  Stock,  Holder shall
thereafter  be entitled to  receive,  in addition to the shares of Common  Stock
receivable upon the exercise of such Warrants, such non-Common Stock dividend as
Holder would have received had the Warrant been exercised  immediately  prior to
such  record  date  for the  dividend.  At the  time  of any  such  dividend  or
distribution,  the Company shall make appropriate  reserves to ensure the timely
performance  of the  provisions  of this section 8.3. If the Company  declares a
cash dividend the Holder shall not be entitled to receive any such dividend.

                  8.4      Definition of Common  Stock.  For the purpose of this
Agreement,  the term Common Stock shall mean the following:

                           (a)      the class of stock  designated as Common 
Stock in the Articles of Incorporation of the Company as may be amended,  or any
other class of stock resulting from successive changes or  reclassifications  of
such Common Stock; and
                           (b) if, as a result of an adjustment made pursuant to
section 8, Holder shall upon
exercise of the Warrants become entitled to receive securities other than Common
Stock,  wherever  appropriate,  all references  herein to shares of Common Stock
shall be deemed to refer to and include such other securities and thereafter the
number of such other securities shall be subject to adjustment from time to time
in a manner and upon terms as nearly equivalent as practicable to the provisions
of this section 8.


<PAGE>



                  9.  Issuance of New Warrant  Certificate.  Upon receipt by the
Company of evidence reasonably satisfactory to it of a loss, theft,  destruction
or mutilation of a Warrant  Certificate,  reimbursement by Holder to the Company
of all  incidental  expenses  and,  in the case of loss,  theft or  destruction,
receipt of indemnity or security from Holder reasonably  satisfactory to it, or,
in the case of a mutilated Warrant Certificate,  upon surrender and cancellation
thereof the Company shall make and deliver a replacement  Warrant Certificate to
Holder.
                  10. Elimination of Fractional Interests. The Company shall not
be required to issue  certificates  representing  fractions  of shares of Common
Stock upon the exercise of the  Warrants.  The Company  shall have the option to
make  payment  in cash in  respect  of any  fractional  shares  or to round  any
fraction up to the nearest whole number of shares of Common Stock.

                  11.  Reservation and Listing of Securities.  The Company shall
at all times reserve and keep available out of its  authorized  shares of Common
Stock,  solely for the purpose of issuance  upon the  exercise of the  Warrants,
such  number of shares of Common  Stock as shall be issuable  upon the  exercise
thereof.  The Company  covenants and agrees that,  upon exercise of the Warrants
and payment of the Exercise Price by Holder, all shares of Common Stock issuable
upon such exercise shall be duly and validly issued, fully paid,  non-assessable
and not subject to the preemptive  rights of any stockholder.  The Company shall
use its best  efforts  to cause all  shares of Common  Stock  issuable  upon the
exercise of the Warrants to be listed  (subject to official  notice of issuance)
on all  securities  exchanges,  if any,  on which the  Common  Stock may then be
listed and/or quoted.
                  12.   Representations   and   Warranties  of  Holder.   Holder
represents  and warrants to the Company that it is an  accredited  investor,  as
defined in Section 501 of Regulations under the Securities Act, the Warrants are
being acquired solely for Holder's own account,  for investment,  and not with a
view to  resale,  distribution,  assignment,  subdivision  or  fractionalization
thereof,   and  Holder  has  no  present  plans  to  enter  into  any  contract,
undertaking, agreement or arrangement for such purpose.


<PAGE>



                  13.  Notice  to  Warrant  Holder.  Nothing  contained  in this
Warrant  Agreement  shall be construed as conferring  upon Holder,  by virtue of
holding  the  Warrants,  the  right to vote,  consent  or  receive  notice  as a
stockholder  in respect of any  meetings  of  stockholders  for the  election of
directors or any other matter,  or as having any rights as a stockholder  of the
Company.  If,  however,  at any time prior to the expiration of the Warrants and
their exercise, any of the following events shall occur:

                  (a) the  Company  shall  take a record of the  holders  of its
shares of Common Stock for the purpose of  entitling  them to receive a dividend
or  distribution  payable  otherwise  than  in  cash,  or  a  cash  dividend  or
distribution  payable  otherwise  than out of current or retained  earnings,  as
indicated by the accounting  treatment  (which  treatment shall be in accordance
with generally accepted accounting  principles) of such dividend or distribution
on the books of the Company; or
                  (b) the  Company  shall offer to all the holders of its Common
Stock any  additional  shares of  capital  stock of the  Company  or  securities
convertible into or exchange for shares of capital stock of the Company,  or any
option, right or warrant to subscribe therefor; or

                  (c)  a  dissolution,   liquidation,   winding  up,   transfer,
consolidation,  or merger) or a sale of all or  substantially  all its property,
assets and business as an entirety shall be proposed;


<PAGE>


the  Company  shall give notice of such event at least 15 days prior to the date
fixed as a record  date or the date of the closing  the  transfer  books for the
determination  of the  stockholders  entitled  to such  dividend,  distribution,
convertible or exchangeable  securities or subscription  rights,  or entitled to
vote on such proposed dissolution,  liquidation, winding up or sale. Such notice
shall specify such record date or the date of closing the transfer books, as the
case may be.  Failure to give such notice or any defect therein shall not affect
the validity of any action taken in connection  with the  declaration or payment
of any  such  dividend,  or the  issuance  of any  convertible  or  exchangeable
securities,  or  subscription  rights,  options  or  warrants,  or any  proposed
dissolution, liquidation, winding up or sale.
