Item 2. Management's Discussion and Analysis of Financial Condition and
          Results of Operations

Overview

         Synaptic Pharmaceutical  Corporation is a biotechnology company engaged
in the  development  of a broad platform of enabling  technology  which it calls
"human   receptor-targeted   drug  design  technology."  It  is  utilizing  this
technology  both to  discover  and clone the genes that code for human  receptor
subtypes  associated  with specific  disorders and to design  compounds that can
potentially be developed as drugs for treating these  disorders.  The Company is
engaged in  collaborations  with four  pharmaceutical  companies:  Eli Lilly and
Company  ("Lilly"),   Merck  &  Co.,  Inc.   ("Merck"),   Novartis  Pharma  A.G.
("Novartis"),  and Warner-Lambert Company  ("Warner-Lambert").  Since inception,
the Company has financed its operations  primarily through the sale of stock and
through funds provided by three of its collaborative partners,  Lilly, Merck and
Novartis,  under  collaborative   agreements.   The  Company  entered  into  its
collaboration  with  Warner-Lambert  in July 1997. The Company also has licensed
certain of its technology to The DuPont Merck  Pharmaceutical  Company  ("DuPont
Merck").

         Under its collaborative agreements,  the Company may receive one or two
types of revenue from its collaborative  partners:  contract revenue and license
revenue.  Contract  revenue  includes  research  funding to support a  specified
number  of the  Company's  scientists  and  payments  upon  the  achievement  of
specified  research and  development  milestones.  Research  funding  revenue is
recognized  ratably over the period of the  agreement to which it relates and is
based  upon  predetermined  funding  requirements.  Research  milestone  payment
revenue is recognized when the related research  milestone is achieved.  License
revenue  represents  non-refundable  payments  for  licenses  to  the  Company's
technology and drug discovery systems.  Non-refundable payments for licenses are
recognized at such time as they are received or, if earlier,  become guaranteed.
In addition to contract revenue and license revenue, if a drug is developed as a
result  of any of the  collaborative  agreements  between  the  Company  and its
collaborative  partners,  the Company is entitled  to receive  royalty  payments
based upon the sale of such  drugs.  The Company  also  receives  revenues  from
government grants under the Small Business  Innovative Research ("SBIR") program
of the National Institutes of Health.

         To  date,  the  Company's  expenditures  have  been  for  research  and
development related expenses, general and administrative related expenses, fixed
asset purchases and various patent related  expenditures  incurred in protecting
the Company's technologies.  The Company has been historically  unprofitable and
had an  accumulated  deficit of  $27,698,000  at September 30, 1997. The Company
expects to continue to incur operating losses for a significant  number of years
and may not become  profitable,  if at all,  until it begins to receive  royalty
revenue.  To date, the Company has not received any royalty revenue and does not
expect to receive such revenue for a significant number of years, if at all.


Results of Operations


Comparison of the Three Months Ended September 30, 1997 and 1996

         Revenues.  The Company  recognized revenue of $2,407,000 and $3,969,000
for the three  months  ended  September  30,  1997 and 1996,  respectively.  The
decrease of $1,562,000 was attributable primarily to: the recognition during the
third quarter of 1996 of $2,000,000 of  non-recurring  license revenue under the
terms  of  one of the  Company's  license  and  collaboration  agreements  and a
decrease in grant revenue of $118,000;  both of which were offset by an increase
in contract  revenue of $556,000 which was primarily due to the expansion of the
Company's collaborative arrangement with Lilly.


                                        5

         Research and Development  Expenses.  The Company incurred  research and
development  expenses of  $3,529,000,  and $3,008,000 for the three months ended
September 30, 1997 and 1996, respectively.  The increase of $521,000, or 17%, in
research and development expenses was attributable  primarily to: an increase of
$325,000 in compensation expense resulting from a net average headcount increase
of 26 research  personnel,  annual salary increases for the scientific staff and
an associated  increase in fringe benefit  expenses;  an increase of $207,000 in
research supply costs; an increase of $131,000 in facility related costs; all of
which was offset by a reduction in grant equipment expense of $175,000.

         General and Administrative  Expenses.  The Company incurred general and
administrative  expenses of $998,000  and  $714,000  for the three  months ended
September 30, 1997 and 1996, respectively. The increase of $284,000, or 40%, was
attributable primarily to $251,000 in patent and patent related expenses for the
quarter ended  September 30, 1997 resulting from the expensing of all patent and
patent application costs as incurred, effective October 1, 1996.

         Other Income,  Net. The Company recorded other income,  net of interest
expense,  of $486,000 and $482,000 for the three months ended September 30, 1997
and 1996, respectively.

         Net (Loss) Income and Net (Loss) Income Per Share. The Company incurred
a net loss of  $1,634,000,  ($0.21 per share),  and had net income of  $729,000,
($0.09 per share),  for the three months ended September 30, 1997, and September
30, 1996,  respectively.  The increase of  $2,363,000  in net loss was primarily
attributable to the  recognition  during the third quarter of 1996 of $2,000,000
of non-recurring license revenue.


Comparison of the Nine Months Ended September 30, 1997 and 1996

         Revenues.  The Company  recognized revenue of $7,959,000 and $7,531,000
for the nine  months  ended  September  30,  1997 and  1996,  respectively.  The
increase  of $428,000  was  attributable  primarily  to: an increase in contract
revenue  of   $2,444,000   resulting   from  the   expansion  of  the  Company's
collaborative  arrangement  with  Lilly  and  increases  in  rates  charged  per
full-time equivalent  scientist under collaborative  arrangements from which the
Company is receiving  funding  partially  offset by a decrease of  $2,000,000 of
non-recurring  license  revenue under the terms of one of the Company's  license
and collaboration agreements during the third quarter of 1996.

         Research and Development  Expenses.  The Company incurred  research and
development  expenses of  $10,220,000,  and $8,492,000 for the nine months ended
September 30, 1997 and 1996, respectively.  The increase of $1,728,000,  or 20%,
in research and development expenses was attributable  primarily to: an increase
of $891,000  in  compensation  expense  resulting  from a net average  headcount
increase of 22 research  personnel,  annual salary  increases for the scientific
staff and an  associated  increase in fringe  benefit  expenses;  an increase of
$606,000 in research supply costs;  an increase of $324,000 in facility  related
costs;  all of which was offset by a  reduction  in grant  equipment  expense of
$175,000.

         General and Administrative  Expenses.  The Company incurred general and
administrative  expenses of $2,920,000  and $2,078,000 for the nine months ended
September 30, 1997 and 1996, respectively. The increase of $842,000, or 41%, was
attributable primarily to $729,000 in patent and patent related expenses for the
nine months ended  September 30, 1997 resulting from the expensing of all patent
and patent application costs as incurred, effective October 1, 1996.

         Other Income,  Net. The Company recorded other income,  net of interest
expense,  of $1,452,000 and  $1,609,000 for the nine months ended  September 30,
1997 and 1996, respectively. The decrease of $157,000 was primarily attributable
to the recognition of gain on sale of securities.

                                        6


<PAGE>



         Net Loss and Net Loss Per Share.  The net loss  incurred by the Company
was $3,729,000 ($0.49 per share),  and $1,430,000 ($0.19 per share) for the nine
months  ended  September  30,  1997 and  1996,  respectively.  The  increase  of
$2,299,000 in net loss was primarily  attributable to the recognition during the
third quarter of 1996 of $2,000,000 of non-recurring license revenue.

         The Company does not believe that  inflation has had a material  impact
on its results of operations for either the three month period or the nine month
period which ended September 30, 1997.


Liquidity and Capital Resources

         At September 30, 1997 and December 31, 1996, cash, cash equivalents and
marketable  securities  were  in  the  aggregate  $30,909,000  and  $34,684,000,
respectively.  The decrease of $3,775,000 was attributable  primarily to the net
loss for the nine months of $3,729,000 and the purchase of capital equipment and
leasehold  improvements of $2,116,000 offset by the receipt in the third quarter
of $1,137,000 in quarterly contract research funding which will be recognized in
the fourth  quarter  and  depreciation  and  amortization  expense  of  $899,000
recorded in its statement of operations for the nine months ended  September 30,
1997. On October 30, 1997, the Company sold 2,500,000  shares of common stock at
$12.625  per  share.  On  November  5,  1997,  the  underwriters   exercised  an
Over-allotment option, granted to them in connection with the Offering, in which
the  Company  sold an  additional  375,000  shares at  $12.625.  Proceeds to the
Company  from the sale of the shares  sold in the  Offering  and the shares sold
pursuant to the  Over-allotment  are $34,141,000  after  deducting  underwriting
commissions. In addition to the cash, cash equivalents and marketable securities
described  above,  the Company had $712,000 in  restricted  cash recorded in its
balance sheet at September 30, 1997.  This restricted cash is held in one of the
Company's  investment  accounts  and secures  lease  payments  to the  Company's
landlord  for one full  year  and  secures  the  outstanding  balance  due on an
equipment lease.

         To date, the Company has met its cash requirements  through the sale of
its stock,  through  licensing  fees,  research  funding and milestone  payments
received  under the  collaborative  agreements  with Lilly,  Merck and Novartis,
through  SBIR  grants and  through  interest  earned on its  investments.  As of
September 30, 1997, the Company had received: approximately $62,000,000 from the
sale of its stock; approximately $46,000,000 in licensing fees, research funding
and  milestone  payments  under its  collaborative  arrangements;  approximately
$3,200,000 in SBIR grants; and approximately $5,900,000 in other income, net. To
date,  the portion of these funds that has been expended by the Company has been
used principally to fund research and development, to purchase fixed assets used
primarily in its  research  activities,  to create its patent  estate and to pay
general and administrative support costs.

         At  September  30,  1997,  the  Company was  involved in  collaborative
arrangements with Lilly, Merck,  Novartis and  Warner-Lambert.  Lilly, Merck and
Novartis are providing research funding to the Company during 1997 and Lilly and
Novartis are expected to provide  research  funding to the Company  during 1998.
The  aggregate  amount of research  funding under these  arrangements  which the
Company  expects to  receive  during the  remainder  of 1997 and during  1998 is
approximately $1,107,000 and $6,678,000,  respectively.  Warner-Lambert does not
currently  provide  research  funding to the Company  and the  Company  does not
expect that such  funding  will be  provided,  if at all,  until 1999.  Research
funding  under the Lilly  agreement is scheduled to expire on December 31, 1998.
Research  funding  under the Merck  agreement is scheduled to expire on November
30, 1997.  Research funding under the Novartis agreements is scheduled to expire
on August 3, 1998.

         At  September  30,  1997,  the Company had  invested  an  aggregate  of
$7,675,000 in property and equipment.  During the first nine months of 1997, the
Company spent approximately $2,116,000 on capital improvements.  Of this amount,
approximately $1,400,000 related to the expansion of laboratory space

                                        7


<PAGE>



and  improvements  to the Company's assay screening  systems.  In addition,  the
Company  continues  to convert  currently  underutilized  space into  laboratory
facilities beyond the level which existed at September 30, 1997.

         The Company leases  laboratory and office facilities under an agreement
expiring on December 31, 1999.  The minimum  annual  payment  under the lease is
$691,000.

         At September 30, 1997 the Company had available  funds of  $30,909,000.
The Company  believes that its cash and marketable  securities on hand, funds it
will receive from its collaborative  partners and under SBIR grants and interest
income,  together with the net proceeds  received from the Offering and from the
shares  sold  pursuant  to the  Over-allotment,  will be  sufficient  to fund an
increased  operating expense level through the year 2000. The Company expects to
continue to incur operating losses for a significant number of years.

         As  of  December  31,  1996,   the  Company  had  net  operating   loss
carryforwards of approximately  $21,000,000 for Federal income tax purposes that
will expire principally in the years 2002 through 2011. In addition, the Company
had research and development credit  carryforwards which will expire principally
in 2002 through 2009. For financial  reporting  purposes,  a valuation allowance
has  been  recognized  to  offset  the  deferred  tax  assets  related  to these
carryforwards.  Due to limitations imposed by the Tax Reform Act of 1986, and as
a result  of a  significant  change  in the  company's  ownership  in 1993,  the
utilization of approximately  $6,000,000 of net operating loss  carryforwards is
subject to annual  limitation.  The  utilization of the research and development
credits is similarly  limited.  A further limitation of the net operating losses
and  research  and  development  credit  carryforwards  may  occur if there is a
further change in ownership in connection with the Offering mentioned above.

         This  management  discussion  and analysis of financial  condition  and
results of operations  includes "forward looking  statements" within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities  Exchange Act of 1934, as amended.  These forward looking  statements
include,  but are not limited  to,  those  relating to future cash and  spending
plans,  amounts of future research funding,  and any other statements  regarding
future  growth,  future  cash  needs,  future  operations,  business  plans  and
financial results, and any other statements which are not historical facts. When
used in this  document,  the words  "expect,"  "may,"  "believes,"  and  similar
expressions  are intended to be among the words that  identify  forward  looking
statements.  Such forward looking  statements  involve risks and  uncertainties,
including,  but not limited to those risks and  uncertainties  and other factors
set forth as "Cautionary Statements" in the Company's Annual Report on Form 10-K
for the year ended  December  31, 1996 or detailed  from time to time in filings
that the company makes with the Securities and Exchange Commission.  The forward
looking  statements  included  herein are  qualified  in their  entirety  by the
Cautionary  Statements.  Should  one or more of  these  risks  or  uncertainties
materialize,  or should underlying assumptions prove incorrect,  actual outcomes
may  vary  from  those  indicated.   Although  the  Company  believes  that  the
expectations  reflected in the forward looking  statements  contained herein are
reasonable,  it can give no assurance  that such  expectations  will prove to be
correct.

                           PART II. OTHER INFORMATION


Item 2.  Changes in Securities and Use of Proceeds


         Securities Act Rule 229.463 ("Rule 463") required  issuers to report on
Form SR their use of proceeds,  following an initial public offering, within ten
days of the first three months  following the effective date of the registration
statement,  and every six months  thereafter,  until the application of all such
proceeds was  complete.  Effective  September  2, 1997,  pursuant to Release No.
34-38850,  the Securities and Exchange  Commission  ("SEC")  amended Rule 463 to
eliminate  Form SR and now  requires  a  first-time  registrant  to  report  the
application  of proceeds in each of its periodic  Exchange Act reports until the
application  of such  proceeds is  complete.  Prior to  September  2, 1997,  the
Company  utilized Form SR to report the application of proceeds  received by the
Company following its initial public offering.

         The information  provided below represents a reasonable estimate of the
cumulative  application,  through  September  30,  1997,  of the net proceeds of
$25,194,000 which were received  following the Company's initial public offering
on December 13, 1995:


Construction of plant, building and facilities                     $   208,000

Purchase and installation of machinery and equipment               $ 2,554,000

Working capital                                                    $11,580,000


         Except for payments described in the following sentence, the cumulative
application of the net offering  proceeds listed above represent direct payments
to others. No payments were made to directors or officers or to their associates
except for payments made in the ordinary  course of business which include,  but
may not be limited to, the payment of officer  salaries,  fringe  benefits,  and
expense reimbursements or compensation paid to directors for their attendance at
board  meetings or for their services  provided to the Company under  consulting
arrangements, if any.

         At September 30, 1997, the status of proceeds pending final application
are as follows:


Temporary investment of proceeds in marketable securities          $10,852,000

                  (a)  General.  The Project  shall be  conducted in two stages:
Stage 1 and Stage 2.

                  (b) Duration of Stage 1. Stage 1 of the Project shall commence
upon the date of the delivery to Warner of the cell membranes  described in Part
A of Schedule II (the "Stage 1  Commencement  Date").  Unless this  Agreement is
terminated  earlier pursuant to Article XIV, Stage 1 of the Project shall end as
of  the  earliest  of  (i)  the  eighteen-month   anniversary  of  the  Stage  1
Commencement  Date,  (ii) the date on which a BACL shall have been identified or
(iii) if Warner shall have delivered the written notice  contemplated  by and in
accordance with Section 14.3(b), the twelve-month anniversary of the delivery by
Synaptic to Warner of the Novel Galanin Receptor referred to therein.

                  (c) Duration of Stage 2. Unless this  Agreement is  terminated
earlier  pursuant to Article XIV and subject to Section  2.1(d),  Stage 2 of the
Project shall  commence on the fifteenth day following the conclusion of Stage 1
(the "Stage 2 Commencement Date"). Stage 2 of the Project shall end on the third
anniversary of the Stage 2 Commencement Date.

                  (d) Suspension of Stage 2 Commencement Date. In the event that
(i) Synaptic  discovers and clones,  at any time during the period commencing on
the twelve-month  anniversary of the Stage 1 Commencement Date and ending on the
eighteen-month  anniversary  thereof,  a Novel Galanin  Receptor and (ii) Warner
terminates this Agreement in part pursuant to Section 14.4(b) due to its failure
to have identified a BACL prior to such eighteen-month anniversary, Warner shall
have the right,  at its option,  to suspend the Stage 2 Commencement  Date until
the six-month  anniversary  (the "Six-Month  Extension  Date") of the date as of
which Synaptic shall have provided to Warner transfected cells or cell membranes
which express the Novel Galanin Receptor.  Such right shall be exercised,  if at
all,  upon written  notice to Synaptic no later than the fifteenth day following
such eighteen-month  anniversary. If Warner exercises its right pursuant to this
Section 2.1(d),  the Stage 2 Commencement  Date shall,  unless this Agreement is
subsequently  terminated  pursuant to Section 14.4(c),  occur  automatically and
without any action on the part of the parties, on the Six-Month Extension Date.

activities with respect to the  commercialization of such Product.  Warner shall
give reasonable  consideration to Synaptic's comments and suggestions concerning
the foregoing.  Synaptic shall be responsible  for paying all costs and expenses
incurred by it in connection with its participation in the foregoing.

                                  ARTICLE VIII
                                    Royalties

         8.0      General.

                  (a)  Royalty  Percentages.  In  further  consideration  of the
licenses granted to Warner hereunder,  Warner shall pay to Synaptic a royalty on
Net Sales of each Product as follows:

                  [**]

                  (b) Royalties on Unpatented Products. In the case of Net Sales
of any  Product  in a  country  in which  the  manufacture,  use or sale of such
Product is not covered by a claim of the


                                                       -13-

<PAGE>



Patent  Rights (an  "Unpatented  Product"),  the rate of the royalty  payable in
respect of such Net Sales  shall be  reduced to  one-half  of the  royalty  rate
payable pursuant to Section 8.0(a).

                  (c) Cost of Goods Sold  Limitation.  Notwithstanding  anything
contained herein to the contrary, the percentage royalty payable in any calendar
quarter with respect to Net Sales of each Product  pursuant to the provisions of
this  Section 8.0 shall be reduced by the number of  percentage  points by which
the Cost of Goods Sold for such Product in such  quarter  exceeds[**] of the Net
Sales of such Product in such quarter.

                  (d) Annual  Reconciliation  of Royalty  Payments Due. If, with
respect to any Product,  the  aggregate  Net Sales in any  calendar  year should
exceed  any of the  thresholds  set forth in  Section  8(a),  then sales of each
category of the Product  (i.e.,  Unpatented  Products and Products  covered by a
claim of the Patent Rights ("Patented  Products")) shall be deemed to have taken
place in the same  proportion  throughout the calendar year and the parties will
reconcile  the payments made by Warner with respect to such calendar year within
ninety days  following the end of any such calendar year.  (For example,  if Net
Sales of Products in any Year totalled $750 million of which $500 million (i.e.,
2/3) were of Patented  Products and $250 million (i.e.,  1/3) were of Unpatented
Products, the royalties due on such sales would be calculated as follows:

                  Patented Products:

                  $250  million x 2/3 at [**]
                  $250  million x 2/3 at [**]
                  $250  million x 2/3 at [**]

                  Unpatented Products:

                  $250  million x 1/3 at [**]
                  $250  million x 1/3 at [**]
                  $250  million x 1/3 at [**]

                  Total royalties = [**]

                  (e) Term of Royalty  Obligation.  Warner's  obligation  to pay
Synaptic  royalties  under this  Agreement  shall commence as of the date of the
first  commercial  sale of a Product for a Project Use and,  subject to the last
sentence of this Section 8.0(e), shall continue (i) for Patented Products, until
the expiration of the last to expire of the Patent Rights  relating to each such
Product and (ii) for Unpatented  Products,  until the tenth  anniversary of such
date of first commercial sale, in each case on a country-by-country  basis. Only
one royalty  will be due on the sale of a specific  Product,  regardless  of the
number of patent claims covering such Product.  If the Patent Rights relating to
a Patented  Product  expire,  lapse or are revoked  before the expiration of ten
years from the launch date in any  country,  the Product  shall be treated as an
Unpatented  Product until (A) if no generic form of the Product is being sold in
such country, the end of the ten-year period and (B) if


                                                       -14-
[** CONFIDENTIAL TREATMENT REQUESTED]
<PAGE>



a  generic  form of the  Product  is  being  sold in such  country,  the  second
anniversary of the later of (x) the first  commercial  sale of such generic form
of the  Product in such  country and (y) the date of such  expiration,  lapse or
revocation and  thereafter,  no royalty shall be payable on such Product in such
country.

         8.1 Currency of Payment. All payments to be made to Synaptic under this
Agreement  shall be made in United States dollars in the United States to a bank
account  designated by Synaptic.  Royalties  earned shall first be determined in
the currency of the country in which they are earned and then converted to their
equivalent  in United  States  currency.  The buying  rates of exchange  for the
currencies  involved  into the currency of the United  States quoted by Citibank
(or its successor in interest) in New York, New York at the close of business on
the last business day of the quarterly period in which the royalties were earned
shall be used to determine any such conversion.

         8.2 Payment and  Reporting.  The  royalties  earned  under  Section 8.0
during any calendar  quarter  shall be paid within sixty days after the close of
such quarter.  With each such quarterly  payment,  Warner shall furnish Synaptic
with  a  royalty  statement  (the  "Royalty  Statement"),  setting  forth  on  a
country-by-country  basis the total number of units of each Product  made,  used
and/or  sold  during the  calendar  quarter  with  respect to which the  royalty
payment is being made.

         8.3 Records.  Warner shall keep,  and shall require its  Affiliates and
permitted  sublicensees  to keep,  accurate  books  and  accounts  of  record in
connection with the manufacture, use and/or sale by or for it of the Products in
sufficient detail to permit accurate  determination of all figures necessary for
verification of royalty obligations set forth in this Article VIII. Such records
shall be  maintained  for a period of three  years  from the end of each year in
which sales occurred.  Synaptic, at its expense, through a nationally recognized
certified  public  accountant,  shall  have the right to access  such  books and
records for the sole purpose of verifying the Royalty Statements, such access to
be conducted after reasonable prior notice by Synaptic to Warner during Warner's
ordinary  business  hours and not more  frequent  than once during each calendar
year.  Synaptics'  certified public accountant shall not disclose to Synaptic or
any other party any information  other than  information that should properly be
contained in a royalty  report  required  under this Agreement and shall sign an
agreement to that effect.  If, as a result of such accounting,  it is determined
that  Synaptic  received at least 5% less than it was properly due in respect of
any quarter, then Warner shall pay to Synaptic, in addition to the amount of the
discrepancy,  (a) interest accrued thereon during the period from the date as of
which such amount was originally due to the date of payment, such interest to be
computed at the average prime rate announced by Citibank N.A. during such period
plus 2%, and (b) an amount equal to the costs reasonably incurred by Synaptic in
conducting  the  accounting  (including  the fees  and  expenses  of  Synaptic's
certified public accountant).

         8.4  Computation  of Royalties.  Sales of Products among Warner and its
Affiliates and permitted  sublicensees  shall not be subject to royalties  under
this  Article  VIII,  but in such  instances  royalties  shall be  payable  upon
Warner's,  its Affiliates' and its permitted  sublicensees' sales to independent
third parties.  Nothing  contained  herein shall obligate Warner to pay Synaptic
more than one royalty on any unit of a Product.

<PAGE>



         8.5 Taxes Withheld. Any income or other tax that Warner, its Affiliates
or  sublicensees  is required to withhold (the  "Withholding  Party") and pay on
behalf  of  Synaptic  hereunder  (the  "Withheld  Party")  with  respect  to the
royalties payable under this Agreement shall be deducted from and offset against
said royalties  prior to remittance to the Withheld  Party;  provided,  however,
that in regard to any tax so deducted, the Withholding Party shall give or cause
to be given to the Withheld Party such assistance as may reasonably be necessary
to enable the Withheld Party to claim  exemption  therefrom or credit  therefor,
and in each case shall furnish the Withheld  Party proper  evidence of the taxes
paid on its behalf.

         8.6  Licenses to  Affiliates.  Each party shall,  at the other  party's
request,  sign license and/or royalty agreements directly with the other party's
Affiliates and permitted  sublicensees in those situations where such agreements
would not decrease the amount of royalties which would be owed  hereunder.  Such
agreements  shall contain the same language as contained herein with appropriate
changes in parties and territory.  No such license and/or royalty agreement will
relieve  Warner of its  obligations  hereunder,  and Warner will  guarantee  the
obligations  of its Affiliate or sublicensee  in any such  agreement.  Royalties
received  directly from Warner's  Affiliates and sublicensees  shall be credited
towards Warner's royalty obligations under Section 8.0.

         8.7 Restrictions on Payment. The obligation to pay royalties under this
Agreement shall be waived and excused to the extent that statutes,  laws,  codes
or government  regulations in a particular country prevent such royalty payments
by the seller of Products,  provided, however, that if legally permissible,  the
seller of Products  shall pay the  royalties  owed to the other party  hereto by
depositing  such  amounts  in a bank  account  in such  country  that  has  been
designated by the party owed such royalties.


                                   ARTICLE IX
                               Milestone Payments

         In addition  to the other  amounts  which  Warner is required to pay to
Synaptic  hereunder and in consideration  for the rights and licenses granted by
Synaptic to Warner hereunder:

         9.0      First Lead Compound Designated by End of Project Term.

                  (a) Milestone  Amounts.  Subject to the  provisions of Article
XIV, with respect to the first Lead Compound  designated by Warner as such prior
to the end of the Project Term, Warner shall become obligated to pay Synaptic:

                  (i) [**] upon the designation of such Compound as a
         Lead Compound;

                  (ii) [**] upon the  acceptance  for filing of the
         first IND covering such Lead Compound;

                  (iii)  [**]  upon  the  commencement  of  Phase  II
clinical trials;

                  (iv)   [**] upon the commencement of Phase III
clinical trials;

                  (v)  [**]  upon  the  sixtieth  day  following  the
         submission  of an NDA  covering  such Lead  Compound  with the FDA or a
         comparable  submission in another Major Market  Country,  provided that
         Warner has not received  written  notice from the FDA or an  equivalent
         foreign  agency during such  sixty-day  period stating that the NDA has
         not been accepted for filing;

                  (vi) [**] upon the approval of an NDA covering such
         Lead  Compound  by the FDA or approval of a  comparable  submission  in
         another Major Market Country; and

                  (vii)  [**] upon the approval for marketing of such
         Lead Compound in a Major Market Country;  provided,  however, that such
         [**]  milestone  payment shall not be payable unless and until an
         NDA covering  such Lead  Compound or a comparable  submission  in Japan
         shall have been approved.

                  (b) Trigger Event.  For convenience of reference,  each of the
events  described in clauses (i) through  (vii) above is referred to herein as a
"Trigger  Event."  Each of the payments  described in clauses (i) through  (vii)
above  shall be due not later  than  thirty  days  following  the  Trigger  Date
described therein.

                  (c)   Exceptions  to  Payment   Obligations.   Notwithstanding
anything contained herein to the contrary, with respect to any Lead Compound for
which Warner becomes obligated to make a milestone payment under any of Sections
9.1 through 9.5, no payment obligation shall arise under Section 9.0(a).

         9.1 Second Lead  Compound  with  Different  Mechanism  of Action.  With
respect  to any Lead  Compound  the  mechanism  of  action of which  involves  a
different Targeted Galanin Receptor than any Lead Compound with respect to which
Warner has previously made the milestone payments referred to in each of clauses
(i) through  (vii) of Section  9.0(a),  Warner  shall  become  obligated to make
milestone  payments to Synaptic  in the amounts and upon the  occurrence  of the
Trigger  Events  described  in clauses  (i)  through  (vii) of  Section  9.0(a);
provided,  however,  that the amount of the milestone payment which Warner shall
become obligated to make pursuant to clause (i) shall be reduced to [**].

         9.2 Third and Each Additional Lead Compound with Different Mechanism of
Action.  With  respect to any Lead  Compound  the  mechanism  of action of which
involves a different  Targeted  Galanin  Receptor than does (a) the mechanism of
action of any Lead Compound with respect to which Warner has  previously  become
obligated  under Section  9.0(a) to make the milestone  payments  referred to in
each of clauses (i) through (vii) thereof and (b) the mechanism of action of

<PAGE>



any Lead Compound with respect to which Warner has previously  become  obligated
under Section 9.1 to make the milestone  payments referred to in each of clauses
(i) through (vii) of Section  9.0(a),  Warner shall become  obligated,  upon the
occurrence  of the Trigger  Events  described  in clauses  (i) through  (vii) of
Section  9.0(a),  to make  milestone  payments to  Synaptic equal to [**] of the
respective amounts set forth in such clauses; provided, however, that the amount
of the  milestone  payment  which  Warner  shall be  obligated  to make upon the
occurrence  of the Trigger  Event  described in clause (i) shall be [**] instead
of   [**].

         9.3  Backup  Compounds.  With  respect to any Lead  Compound  that is a
backup  compound  (the "Backup  Compound")  for a Lead  Compound with respect to
which Warner has previously  become  obligated under Sections 9.0, 9.1 or 9.2 to
make any of the milestone  payments  referred to in such sections (the "Replaced
Compound"),  Warner shall become obligated,  upon the occurrence of each Trigger
Event with respect to such Backup Compound, to make the corresponding  milestone
payment under such sections to Synaptic; provided, however, that no such payment
obligation  shall arise upon the occurrence of any Trigger Event if such Trigger
Event (a) would not have  triggered  a payment  obligation  with  respect to the
Replaced  Compound or (b) had  previously  occurred with respect to the Replaced
Compound.

         9.4 Second Generation  Compounds.  With respect to any Lead Compound (a
"Second  Generation  Compound") that is a second  generation  compound of a Lead
Compound  with respect to which Warner has  previously  become  obligated  under
Sections 9.0, 9.1, 9.2 or 9.3 to make all of the milestone  payments referred to
in such  sections,  Warner shall become  obligated,  upon the occurrence of each
Trigger  Event  referred  to in  clauses  [**] of Section  9.0(a)  with
respect to such Second Generation Compound, to make the corresponding  milestone
payment under such sections to Synaptic, but only to the extent of [**] thereof.

         9.5 Same Compound but Different  Therapeutic  Indication.  In the event
that any Lead Compound (an  "Additional  Indication  Compound")  with respect to
which Warner has previously  become  obligated under Sections 9.0, 9.1, 9.2, 9.3
or 9.4 to make any of the  milestone  payments  referred to in such  sections is
pursued for a therapeutic  indication  which is different  from the  therapeutic
indication  that  was its  focus at the time  that any such  payment  obligation
arose, Warner shall become obligated,  upon the occurrence of each Trigger Event
referred to in clauses (i) through (vii) of Section  9.0(a) with respect to such
Additional  Indication  Compound,  to make the  corresponding  milestone payment
under  such  sections  to  Synaptic;  provided,  however,  that no such  payment
obligation  shall arise upon the  occurrence of the Trigger Event referred to in
[**] if such  Trigger  Event had  previously occurred with respect to such
Compound.

                            Compounds in Development

         In lieu of the provisions  contained in Section 8.0 and Article IX, the
following  provisions of this Article X shall apply to any chemical  entity with
respect to which GLP toxicology  studies have either commenced or been completed
as of the Effective  Date (any such chemical  entity being referred to herein as
an "Other Compound"):

         Section 10.1 Pre-Phase II Completion Other Compound. In the case of any
Other  Compound  which (a) Warner is  developing  for a  particular  therapeutic
indication (the "Original  Indication"),  (b) has not undergone clinical testing
beyond Phase II clinical trials (or comparable trials outside the United States)
and (c) is determined to have activity measured at one or more Galanin Receptors
included within Synaptic  Background  Technology or Project  Technology,  Warner
shall pay Synaptic royalties and milestones as follows:

                  (i) If Warner  continues to develop the Other Compound for the
         Original  Indication and does not utilize the  information  relating to
         the Other Compound's  galanin activity in any way,  including,  without
         limitation,  in its FDA (or comparable foreign) registration package or
         its  promotional  or  other  marketing   activities  relating  to  such
         Compound,  then  Warner  shall  not be  required  to pay  Synaptic  any
         royalties or milestones with respect to such Compound;

                  (ii) If Warner continues to develop the Other Compound for the
         Original  Indication  (and not for a new therapeutic  indication),  but
         utilizes  the  information  relating  to the Other  Compound's  galanin
         activity  either (A) in its  development of such Other Compound and the
         Original Indication involves the diagnosis,  treatment or prevention of
         the condition  implicated by the galanin activity or (B) in its FDA (or
         comparable  foreign)  registration  package or its promotional or other
         marketing  activities  relating to such Compound,  then Warner shall be
         required to pay Synaptic [**] of the  royalties  payable  under Article
         VIII and [**] of any  milestones  payable  under  Article IX; provided,
         however,  that such  milestones  shall be payable  only with respect to
         Trigger Events which as of the time the  information  was generated had
         not previously occurred; and

                  (iii)  If  Warner  develops  the  Other  Compound  for  a  new
         therapeutic  indication  in  addition  to or in  lieu  of the  Original
         Indication  and  utilizes  the   information   relating  to  the  Other
         Compound's  galanin  activity either (A) to develop such Other Compound
         for  such  new  indication  or (B) in its FDA (or  comparable  foreign)
         registration  package or its promotional or other marketing  activities
         relating  to such  Compound,  then  Warner  shall  be  required  to pay
         Synaptic [**] of  the  royalties payable under Article VIII and [**] of
         any  milestones  payable  under  Article IX;  provided,  however,  that
         such milestones  shall be payable only with respect to Trigger  Events 
         which as of the  time  the  information  was  generated  had  not
         previously occurred.

         Section 10.2 Post-Phase II Completion  Other  Compound.  In the case of
any Other  Compound  (a) with  respect  to which  Phase II  clinical  trials (or
comparable  trials outside the United States) have been  successfully  completed
for an Original Indication and (b) which is determined to have activity measured
at one or more Galanin Receptors included within Synaptic Background  Technology
or Project  Technology,  Warner shall pay Synaptic  royalties and  milestones as
follows:

                  (i) If Warner  continues to develop the Other Compound for the
         Original  Indication and does not utilize the  information  relating to
         the Other Compound's galanin activity in any way, then Warner shall not
         be required to pay Synaptic any royalties or milestones with respect to
         such Compound;

                  (ii) If Warner continues to develop the Other Compound for the
         Original  Indication  (and not for a new therapeutic  indication),  but
         utilizes  the  information  relating  to the Other  Compound's  galanin
         activity  either (A) in its  development of such Other Compound and the
         Original Indication involves the diagnosis,  treatment or prevention of
         the condition  implicated by the galanin activity or (B) in its FDA (or
         comparable  foreign)  registration  package or its promotional or other
         marketing  activities  relating to such Compound,  then Warner shall be
         required to pay Synaptic [**] of the  royalties  payable  under Article
         VIII and [**] of any  milestones  payable  under  Article IX; provided,
         however,  that such  milestones  shall be payable  only with respect to
         Trigger Events which as of the time the  information  was generated had
         not previously occurred; and

                  (iii)  If  Warner  develops  the  Other  Compound  for  a  new
         therapeutic  indication  in  addition  to or in  lieu  of the  Original
         Indication  and  utilizes  the   information   relating  to  the  Other
         Compound's  galanin  activity either (A) to develop such Other Compound
         for  such  new  indication  or (B) in its FDA (or  comparable  foreign)
         registration  package or its promotional or other marketing  activities
         relating  to such  Compound,  then  Warner  shall  be  required  to pay
         Synaptic [**]of the royalties payable under Article VIII and [**]of any
         milestones  payable  under  Article IX;  provided,  however,  that such
         milestones  shall be payable only with respect to Trigger  Events which
         as of the  time  the  information  was  generated  had  not  previously
         occurred.

employee's rights and for assigning such rights to the other party.

         11.2     Preparation, Filing and Prosecution of Patent Applications.

                  (a) Responsible  Party.  Synaptic shall be responsible for the
preparation,   filing,  prosecution,  and  maintenance  of  patents  and  patent
applications  included within Synaptic  Background  Technology and within Patent
Rights owned or  controlled  by Synaptic.  Warner shall be  responsible  for the
preparation,   filing,  prosecution,  and  maintenance  of  patents  and  patent
applications  included  within  Patent  Rights  owned or  controlled  by Warner.
Whichever  of Synaptic or Warner is the  responsible  party shall keep the other
party fully informed  concerning its activities pursuant to this Section 11.2(a)
and shall  provide the other party with a reasonable  opportunity  to review and
comment on all substantive  actions which could  materially  affect the scope or
validity  of the patent  coverage  which may  result in  advance of taking  such
action. All review and comment by the non-responsible party shall be carried out
promptly.

                  (b) Assistance.  If so requested by the responsible party, the
other party shall  provide  reasonable  assistance to the  responsible  party in
order to obtain the optimum  patent  protection  for any invention  covered by a
claim  of  a  patent  or  patent  application  prepared,  filed,  prosecuted  or
maintained pursuant to Section 11.2(a).

                  (c)  Abandonment.   If  at  any  time  the  responsible  party
determines  not to  prepare,  file,  prosecute,  or  maintain a patent or patent
application  for which it is responsible to do so, such  responsible  party will
promptly  notify the other party of its  determination  within a time frame that
insures no loss of potential patent  protection.  If the other party then wishes
to pursue any such  patent or patent  application  the  responsible  party shall
assign  its  rights to the other  party  subject to the grant back to it by such
other  party of a  royalty-free  nonexclusive  license  under any such patent or
patent  application.  The other party shall thereafter be the responsible  party
pursuant  to Section  11.2(a)  and the  initial  responsible  party  shall fully
cooperate  with  the  other  party  in its  pursuit  of such  patent  or  patent
application.

         11.3 Third Party Infringement.  In the event Synaptic or Warner becomes
aware of any actual or  threatened  infringement  of any Patent  Right of either
party which claims an invention,  that party shall promptly notify the other and
the Management  Committee  shall  promptly  discuss how to proceed in connection
with such actual or threatened infringement.  In the conduct of any legal action
pursuant to this Section 11.3, (i) if one party  proceeds,  the actual costs and
expenses of such action shall be reimbursed  first to such party and then to the
other party out of any damages or other  monetary  awards  recovered  therein in
favor of Warner or Synaptic or (ii) if both  parties  proceed,  the actual costs
and  expenses  of such action  shall be  reimbursed  proportionally  between the
parties out of any damages or other monetary awards  recovered  therein in favor
or Warner or Synaptic,  based on the actual costs and expenses  incurred by each
party in connection  with such action.  Any remaining  damages or other monetary
recovery shall be divided as follows: (a) under case (i) [**] to the party which
proceeds and [**]to the party which does not proceed; and (b) under case (ii) in
the same  proportion as is applicable to the actual costs and expenses  incurred
by each party in  connection  with such action.  If either party  commences  any
actions or  proceedings  (legal or otherwise)  pursuant to this Section 11.3, it
shall  prosecute  the same  vigorously  at its  expense and shall not abandon or
compromise  them or fail to  exercise  any rights of appeal  without  giving the
other party the right to take over the prosecuting party's conduct at such other
party's own expense.

         11.4     Allegations of Infringement by Third Parties.

                  (a) Licenses Under Third Parties' Patents. If Warner should be
of the opinion that it cannot commercially  reasonably make, import, use, market
and/or  sell a  Product  without  infringing  a third  party's  patent  or other
intellectual  property  rights,  it shall  notify  Synaptic  and may endeavor to
secure a license from the third party on terms that are acceptable to Warner. If
such a license is secured, then [**]of any payments payable by Warner thereunder
shall be  deducted  from  royalty  payments  due to  Synaptic  pursuant  to this
Agreement with respect to such Product in such country;  [**]

                  (b) Defense of Suits by Third  Parties  Relating to  Products.
Warner shall be solely responsible for any threatened or actual claims for third
party  patent  infringement  or other third party  intellectual  property  right
arising out of the  manufacture,  use, sale or  importation  of a Product.  Upon
receiving notice of such actual or threatened claims, Warner shall promptly meet
with  Synaptic  to discuss the course of action to be taken to resolve or defend
any such  infringement  litigation.  [**]

                  (c)  Defense of Suits by Third  Parties  Relating  to Research
Activities.  Each party shall be solely responsible for any threatened or actual
claims for third party infringement or other third party  intellectual  property
right  arising out of its own research  activities in the course of carrying out
the Project.

                  (d)  Pre-Existing  Infringement  Claims.  Notwithstanding  the
foregoing,  each party will pay 100% of any costs and  expenses  and  damages or
other  consideration  resulting from a third party patent infringement action if
it relates solely to allegations of  infringement  made against such party prior
to the Effective Date.

be in default of any of its material  obligations under this Agreement and shall
fail to cure such default within sixty days following  receipt of written notice
thereof  from the other party (the  "Nondefaulting  Party"),  the  Nondefaulting
Party shall have the option of  terminating  this  Agreement  by giving  written
notice of termination to the Defaulting Party.

         14.1 Insolvency, Etc. Either party shall have the right, at its option,
to terminate this Agreement upon written notice to the other party if such other
party  shall  become  insolvent  or  involved  in  dissolution,   bankruptcy  or
receivership  proceedings affecting the operation of such other party's business
to such an extent  as to  render it  incapable  of  fulfilling  its  obligations
hereunder;  provided,  however,  that  if  such  proceeding  is  an  involuntary

         15.4     Partial Termination Pursuant to Section 14.5(b).

                  (a) Restrictive  Covenant.  Upon the occurrence of any partial
termination by Synaptic pursuant to Section 14.5(b), (i) Synaptic shall have the
right to use all Warner  Project  Technology  (excluding  chemical  entities but
including,  without  limitation,  data  relating  to chemical  entities  and SAR
activity  thereof and any data relating to preclinical  and clinical trials with
respect to such  chemical  entities) to  discover,  develop,  manufacture,  have
manufactured,  use and sell  pharmaceutical  products the mechanism of action of
which involves the Galanin  Receptor with respect to which Warner's  rights were
terminated  pursuant to such section and (ii) Warner shall be prohibited,  for a
period of [**] years commencing on the effective date of such termination,  from
attempting to discover,  develop,  manufacture,  use, have manufactured,  use or

Galanin  Receptor  that is included  within  Synaptic  Background  Technology or
Synaptic  Project  Technology but that is not the Targeted Galanin Receptor of a
BACL or a Lead Compound referred to in Section 14.5(b).

                  (b)  Survival  of  Certain  Provisions.   In  the  case  of  a
termination by Synaptic pursuant to Section 14.5(b), the license grant set forth
in  Section  7.0  shall,  to the  extent  that it  covers  the  use of  Synaptic
Background  Technology,  Synaptic Project  Technology and Synaptic Patent Rights
for the purpose of discovering, developing,  manufacturing, having manufactured,
using and selling,  for Project Uses,  Products the mechanism of action of which
involves  any  Galanin  Receptor  other than the  Targeted  Galanin  Receptor(s)
referred to in Section  14.5(b),  terminate;  and all other  provisions  of this
Agreement  shall,  except to the extent  inconsistent  with Section  15.4(a) and
unless terminated  pursuant to another provision of this Article XV, survive any
such termination until the last expiration of any royalty obligation pursuant to
Article VIII or Article X.

         15.5     Partial Termination Pursuant to Section 14.6 or Section 14.7.

                  (a)   Restrictive   Covenant.   Upon  the  occurrence  of  any
termination  by Synaptic  pursuant to Section  14.6 or Section  14.7 of Warner's

(i)  Synaptic  shall  have  the  right  to use  all  Warner  Project  Technology
(excluding chemical entities but including, without limitation, data relating to
chemical  entities and SAR activity thereof and any data relating to preclinical
and  clinical  trials  with  respect to such  chemical  entities)  to  discover,
develop,  manufacture,  have manufactured,  use and sell pharmaceutical products
the mechanism of action of which  involves the Galanin  Receptor with respect to
which Warner's rights were  terminated  pursuant to such section and (ii) Warner
shall be prohibited, for a period of [**] years commencing on the effective date
of such termination,  from attempting to discover,  develop,  manufacture,  have

                  (b)  Survival  of  Certain  Provisions.   In  the  case  of  a
termination  by Synaptic  pursuant to Section 14.6 or Section 14.7,  the license
grant set forth in Section  7.0 shall,  to the extent  that it covers the use of
Synaptic Background Technology,  Synaptic Project Technology and Synaptic Patent
Rights  for  the  purpose  of  discovering,  developing,  manufacturing,  having
manufactured,  using and selling,  for Project  Uses,  Products the mechanism of
action of which involves the Targeted Galanin Receptor(s) referred to in Section
14.6 or Section 14.7,  terminate;  and all other  provisions  of this  Agreement
shall,  except to the  extent  inconsistent  with  Section  15.5(a)  and  unless
terminated  pursuant to another  provision of this Article XV,  survive any such
termination  until the last  expiration  of any royalty  obligation  pursuant to
Article VIII or Article X.

         15.6 Option to Acquire License;  Payments to Warner.  Subsequent to the
designation  of a Lead  Compound,  in the  event of a  termination  pursuant  to
Section 14.6 or Section 14.7 with respect to such Lead Compound,  Synaptic shall
have an  option  to  obtain  an  exclusive  license  with  the  right  to  grant
sublicenses  under any Warner  Patent  Right  covering  such Lead  Compound.  If
Synaptic  exercises such option and develops and markets the Lead  Compound,  it
shall pay Warner  the same  percentage  royalties  on the net sales of such Lead
Compound  that Warner  would have been  required to pay Synaptic had it marketed
such Lead Compound. If Synaptic exercises such option and sublicenses its rights
under any such Patent Right to a third  party,  then  Synaptic  shall pay Warner
compensation  based upon the stage of  development  of such Lead Compound at the
time of the termination pursuant to Section 14.6 or 14.7. Such compensation will
be in an amount  equal to a percentage  of any  development  milestone  payments
which  Synaptic  receives from such third party licensee in respect of such Lead
Compound and a percentage of any  royalties  which  Synaptic  receives from such
third party in respect of such Lead Compound, as follows:

                  If the Termination Occurs:               Applicable Percentage

                  (i)   Prior to completion of Phase II              [**]

                  (ii)  After completion of Phase II but             [**]
                           prior to completion of Phase III

                  (iii) After completion of Phase III but            [**]
                           prior to NDA approval

                  (iv)  After NDA approval                           [**]

         15.7 Survival of Accrued  Rights.  Notwithstanding  anything  contained
herein to the contrary,  termination of this Agreement,  in whole or in part, in
accordance  with this  Article  XV shall be without  prejudice  to the rights of
either party  against the other party accrued or accruing  under this  Agreement
prior to the termination,  including the obligation to pay royalties pursuant to
the terms hereof.

                         Representations and Warranties

         16.1  Synaptic   Prohibition  Against  Certain  Third  Party  Licenses.
Synaptic  agrees that it will not at any time grant to any third party a license
to use its technology to develop compounds that bind G protein-coupled receptors
other  than  Galanin  Receptors  with an  affinity  which is less than ten times
greater  than their  affinity  for any Galanin  Receptor  with  respect to which
Warner has an exclusive license at such time.

         16.2  Warner  Limitations  on Certain  Development  Activities.  Warner
acknowledges  that  Synaptic  has  licensed  its  technology  relating  to alpha
adrenergic,  neuropeptide  Y  and  serotonin  receptors  to  third  parties  and
understands and agrees that it is not receiving any right or license to use such
technology  hereunder and may not develop or commercialize any compound which is
an agonist or antagonist of a Galanin Receptor  included in Synaptic  Background
Technology  or Project  Technology  unless the affinity of any such compound for
any such  receptor  is at least  ten-fold  less than its  affinity  for any such
Galanin Receptor.

         16.3  Cost of Goods  Sold  Experience.  Warner  hereby  represents  and
warrants that not more than [**] of the pharmaceutical  products currently being
promoted by Warner have Cost of Goods Sold which  exceed [**]of the Net Sales of
such products, as computed on a product-by-product basis.


                                  ARTICLE XVII
                            Miscellaneous Provisions

         17.0 No Agency.  It is  understood  and agreed that Synaptic and Warner
shall each have the status of an independent contractor under this Agreement and
that nothing in this Agreement  shall be construed as  authorization  for either
party to act as agent for the other party.

         17.1 Governing  Law. This Agreement  shall be governed by and construed
in  accordance  with the laws of the  State of New  Jersey  (without  regard  to
principles of conflicts of laws).

Agreement  shall be in writing  and shall be sent by first  class  certified  or
registered mail, postage prepaid,  or by express courier services,  addressed to
the party to be notified at its address shown below or such other address as may
have been furnished in writing to the notifying party.

(whether similar or dissimilar) or of any subsequent breach thereof.

         17.5  Indemnification.  Warner  agrees to indemnify  and hold  harmless
Synaptic and its affiliates and their respective  employees,  agents,  officers,
directors  and  permitted  assigns from and against any claims by a third party,
and any resulting judgments,  expenses (including  reasonable  attorney's fees),
losses, liabilities, damages and awards arising out of or resulting from (a) its
negligence  or  willful  misconduct,  (b) a  breach  of any of its  obligations,
representations   or  warranties   hereunder  or  (c)  its  performance  of  its
obligations hereunder,  including, without limitation, its testing, manufacture,
use or sale of any Product or other chemical  entity,  except to the extent that
such claim results from any negligence or willful  misconduct of any such person
seeking to be indemnified hereunder.

         Synaptic  shall  indemnify and hold harmless  Warner and its affiliates
and their  respective  employees,  agents,  officers,  directors  and  permitted
assigns  from  and  against  any  claims  by a third  party,  and any  resulting
judgments, expenses (including reasonable attorney's fees), losses, liabilities,
damages  and awards  arising  out of or  resulting  from (a) its  negligence  or
willful misconduct,  (b) a breach of any of its obligations,  representations or
warranties hereunder or (c) its performance of its obligations hereunder, except
to the extent that such claim results from any negligence or willful  misconduct
of any such person seeking to be indemnified hereunder.

         Whenever any person seeking to be indemnified hereunder has information
from which it may reasonably  conclude an incident has occurred which could give
rise to a claim for  indemnification  under this Section 17.5, such person shall
promptly give notice to the indemnifying party of all pertinent data surrounding
such incident and, in the event a claim is made or suit is brought,  all persons
seeking indemnification shall assist the indemnifying party and cooperate in the
gathering of information  with respect to the time,  place and  circumstances of
such incident and in obtaining  the names and  addresses of any injured  parties
and available witnesses.  If the indemnifying party has accepted  responsibility
for  indemnifying  the person  seeking  indemnification  hereunder  by providing
prompt written notice to such person,  and such indemnifying party is diligently
defending or attempting to settle the subject claim, then (i) the person seeking
indemnification  shall not voluntarily  make any payment or incur any expense in
connection  with any such  claim  without  the  prior  written  consent  of such
indemnifying  party and (ii) the indemnifying party shall have sole control over
the  defense  and  settlement  of any  claim  with  respect  to  which it may be
obligated to provide indemnification  hereunder. If the indemnifying party fails
to   diligently   defend  or  settle   any  claim,   then  the  person   seeking
indemnification  shall have the right to assume  control  over the  defense  and
settlement of such claim at the expense of the indemnifying party.

however,  that Warner may assign this Agreement to a wholly-owned  subsidiary of
Warner  in  connection  with  a  reorganization   of  Warner  involving  all  or
substantially all of its research and development assets.
