      of  Organon  and  its  Affiliates  ("Organon's  knowledge"),   to   which
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE SECURITIES AND EXCHANGE COMMISSION]  is  a  party  which  relates  to
      Organon Patent Rights, Organon Technical Information, the Compound or the
      Current Product, which violation would have an MAE;

            (iii)    This  Agreement  has  been  duly executed and delivered by
      Organon and constitutes the valid, binding and  enforceable obligation of
      Organon;

            (iv)    (a)  The Organon Patent Rights, as set  forth  on  Schedule
      1.94, and Organon Technical Information licensed hereunder constitute all
      of the intellectual  property  and know-how under its and its Affiliates'
      control with respect to the manufacture,  use,  sale,  offer  to  sell or
      import of the Compound and the Current Product; (b) Organon is the  legal
      and  beneficial  owner  of  all  Organon  Patent  Rights  (other than the
      [CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND FURNISHED SEPARATELY  TO
      THE SECURITIES AND EXCHANGE COMMISSION]  Patent  Rights)  and all Organon
      Technical  Information, and no other person, firm, corporation  or  other
      entity has any  right,  interest  or  claim in or to, and Organon has not
      entered any agreement (other than the [CONFIDENTIAL  INFORMATION HAS BEEN
      OMITTED   AND  FURNISHED  SEPARATELY  TO  THE  SECURITIES  AND   EXCHANGE
      COMMISSION]  Agreement)  granting  any right, interest or claim in or to,
      the Organon Patent Rights or Organon  Technical Information; and (c) none
      of the Organon Patent Rights (other than  the  [CONFIDENTIAL  INFORMATION
      HAS BEEN OMITTED AND FURNISHED SEPARATELY TO THE SECURITIES AND  EXCHANGE
      COMMISSION]  Patent  Rights)  (and  to  Organon's  knowledge, none of the
      [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY  TO
      THE  SECURITIES AND  EXCHANGE  COMMISSION]Patent  Rights)  are  currently
      involved  in  any  interference,  reissue,  reexamination,  or opposition
      proceeding,  and  neither Organon nor any of its Affiliates has  received
      any written notice from any Third Party of any actual or threatened claim
      or assertion to the contrary;

            (v)   To Organon's knowledge:  (a) no Third Party is infringing any
      claims of any issued patents encompassed within the Organon Patent Rights
      with respect to the  Product; and (b) the manufacture, use sale, offer to
      sell or import by Pfizer  or  Organon  of  the  Compound  or  the Current
      Product  does not and will not infringe the intellectual property  rights
      of any Third  Party.   Neither  Organon  nor  any  of  its Affiliates has
      received a notice, claim or assertion from any Third Party  to the effect
      thereof,  or  that  challenges or questions the right of Organon  or  its

      Information to manufacture,  use,  sell,  offer  to  sell  or  import the
      Compound  or  the  Current  Product. Organon has furnished to Pfizer  all
      material information in its possession  requested  by  Pfizer  as  to the
      foregoing  statements.  The

      Organon  Patent  Rights  include  claims  that by  their  terms  would be
      infringed  by making,  having  made,  using,  selling and having sold the
      Current Product in the Countries covered by the Organon Patent Rights. To

      Rights and the  [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED
      SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]  Patent Rights are
      valid and enforceable.

            (vi)  None  of  the  rights  granted (or intended to be granted) to
      Pfizer by Organon hereunder, including  without  limitation  the  Organon
      Patent  Rights (other than the [CONFIDENTIAL INFORMATION HAS BEEN OMITTED
      AND FURNISHED  SEPARATELY  TO  THE  SECURITIES  AND  EXCHANGE COMMISSION]

      lien, charge, claim, pledge, security interest, charge,  conditional sale
      agreement  or other title retention agreement, lease, mortgage,  security
      agreement, option  or other encumbrance (including without limitation the
      filing of, or agreement  to  give,  any  financing  statement  under  the
      Uniform  Commercial Code of any jurisdiction in the US Territory or other
      comparable filing in any other Country in the Territory);

            (vii) Schedule  1.94  sets  forth  a  true and complete list of all
      Organon Patent Rights (other than the [CONFIDENTIAL  INFORMATION HAS BEEN
      OMITTED   AND  FURNISHED  SEPARATELY  TO  THE  SECURITIES  AND   EXCHANGE
      COMMISSION]  Patent  Rights),  and to the Organon's knowledge, a true and
      complete  list of the [CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED  AND

            (viii) Schedule 3.1(viii) contains  a complete list of all material
      agreements with Third Parties relating to the development and manufacture
      of the Product.  Organon has previously disclosed  and  provided complete
      copies  to  Pfizer  of  all  such  agreements,  none  of which have  been
      modified, supplemented or amended;

            (ix)  There is no Proceeding pending with respect  to  the  Organon
      Patent  Rights (other than the [CONFIDENTIAL INFORMATION HAS BEEN OMITTED
      AND FURNISHED  SEPARATELY  TO  THE  SECURITIES  AND  EXCHANGE COMMISSION]
      Patent  Rights),  Organon  Technical  Information,  the Compound  or  the
      Current  Product,  including  without limitation to the  conduct  of  any
      clinical trials, manufacturing activities or other activities relating to
      the transactions contemplated by the Alliance Agreements, or to Organon's
      knowledge, pending with respect to the [CONFIDENTIAL INFORMATION HAS BEEN

      COMMISSION]  Patent  Rights.   To  Organon's  knowledge,   there   is  no
      Proceeding  threatened  against  Organon or [CONFIDENTIAL INFORMATION HAS

      Organon  and  its  Affiliates relating to the Compound  and  the  Product
      including,   without  limitation,   the   manufacturing   thereof.    The
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE SECURITIES AND EXCHANGE COMMISSION]  Agreement  is  in full force and
      effect,  all payments to date required to be made thereunder  by  Organon
      and its Affiliates,  as applicable, have been made,


                                       22




      and no  default  exists  under  the  [CONFIDENTIAL  INFORMATION  HAS BEEN
      OMITTED  AND  FURNISHED   SEPARATELY  TO  THE   SECURITIES  AND  EXCHANGE
      COMMISSION] Agreement;

            (xi)    Organon  has  disclosed  to Pfizer all material information
      known  to  Organon  or its Affiliates relating  to  (i)  the  safety  and
      efficacy  of  the Product  and  the  Compound,  (ii)  the  drug  quality,

      and the Compound;

            (xii)   All manufacturing operations  conducted  by Organon and its
      Affiliates  (or  by  Third  Parties  on  their  behalf) relating  to  the
      manufacturing of the clinical supplies of the Current  Product  are being
      conducted   in   material  compliance  with  cGMP  and  other  applicable
      requirements and standards  of  any  Governmental Authority in which such

            (xiii) Organon represents and warrants  that Organon  together with
      the entities listed in the definition of "Organon Group Parent" represent
      the  companies  through  which  Organon  conducts  its  most  significant

      on its financial  condition  or on its ability to perform its obligations
      hereunder; and


                                       23






            (iii) This Agreement has been duly executed and delivered by Pfizer

                                  ARTICLE 4

                             PRODUCT DEVELOPMENT


      4.1 Development Plan and  Budgets.  The  Parties  will jointly pursue the
Development of the Product to attain the attributes as described in the Product
Profile in accordance with the Development Plan, as such Product Profile may be
revised by mutual agreement of the Parties pursuant to Article  10.   The draft
of  the initial Development Plan is attached to this Agreement as Schedule 4.1.
Such  plan  will  be  reviewed  and  modified as deemed appropriate by the CDRC
commencing promptly after the Effective Date.  Thereafter, the Development Plan
will be reviewed by the CDRC at least  every  six  (6) months and updated on at
least an annual basis (or more frequently as may be  determined  by  the CDRC).
The Parties agree that beginning on the Effective Date, they will discuss those
activities  that  are  reasonably


                                       24




necessary for the  Development of the Product,  with Pfizer taking the lead and
having the right to  [CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND FURNISHED
SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION].

      4.2 Completed  and  Ongoing  Studies.  Promptly after the Effective Date,
Organon shall provide to Pfizer a list of the  Product  Studies  that have been
completed  to  date on the Product, as well as a list of those Product  Studies
that are in the process of being conducted.

      4.3 Budget  Planning.  The  Parties  will on or before October 31 of each
Year (commencing with the Second Year) determine  the  budget to be included in
the  Development  Plan  for  the subsequent Year, and agree  on  a  non-binding
forecast for the subsequent Year.

      4.4 Development Costs.

            (i)   Subject to this  Article  4.4, all Development Costs incurred
      by the Parties in the Development of the  Product,  including Development
      Costs  incurred by Organon prior to the Effective Date,  will  be  shared
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE   SECURITIES   AND   EXCHANGE  COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO THE SECURITIES
      AND EXCHANGE COMMISSION]%) by Pfizer  and  [CONFIDENTIAL  INFORMATION HAS
      BEEN  OMITTED  AND  FURNISHED  SEPARATELY TO THE SECURITIES AND  EXCHANGE
      COMMISSION]  percent ([CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED  AND
      FURNISHED SEPARATELY  TO  THE  SECURITIES  AND  EXCHANGE COMMISSION]%) by
      Organon,  provided,  however,  that Pfizer's share of  Development  Costs
      incurred by Organon prior to the  Effective  Date (the "Prior Development
      Costs") shall not exceed $[CONFIDENTIAL INFORMATION  HAS BEEN OMITTED AND
      FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION]  USD  in
      total.  Promptly after execution of this Agreement, Organon shall provide
      Pfizer with  supporting  information  setting forth, in detail, the then-
      current Prior Development Costs incurred  by  Organon  and  a forecast of
      additional Prior Development Costs that Organon expects to incur prior to
      the  Effective  Date.  Within five (5) Business Days after the  Effective
      Date, Organon shall  provide  Pfizer with a final accounting of the Prior
      Development Costs, and Pfizer shall  have  fifteen  (15) Business Days to
      review such accounting.  Within twenty (20) Business  Days  of receipt of
      such  accounting, Pfizer shall pay, in accordance with Article  9.5,  its
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE   SECURITIES   AND   EXCHANGE  COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO THE SECURITIES
      AND EXCHANGE COMMISSION]%) share of all such Prior Development Costs that
      are not in good faith disputed by Pfizer.

            (ii)  If Pfizer declines to exercise  its  rights to terminate this
      Agreement either under (x) Article 13.5(i)(c) based on the results of the
      [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY  TO
      THE SECURITIES AND EXCHANGE COMMISSION]; or (y) Article 13.5(ii)(a) based
      on the results of  the  [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND
      FURNISHED  SEPARATELY  TO THE SECURITIES AND EXCHANGE COMMISSION],  then,
      commencing with the date  on  which  all  of  Pfizer's termination rights
      under  those Articles have expired (the "Adjustment  Date"),  Development
      Costs for  the Current Product for the Initial Indications will be shared
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE   SECURITIES   AND   EXCHANGE  COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO THE SECURITIES
      AND EXCHANGE COMMISSION]%) by Pfizer  and  [CONFIDENTIAL  INFORMATION HAS
      BEEN  OMITTED  AND  FURNISHED  SEPARATELY TO


                                       25




      THE   SECURITIES   AND  EXCHANGE   COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION  HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO THE SECURITIES
      AND EXCHANGE  COMMISSION]%)  by Organon,  and such  adjustment  will also
      apply  retroactively,  subject  to the  limitation  described  in Article
      4.4(i), for all Development Costs for the Current Product for the Initial
      Indications incurred by the Parties prior to the Adjustment Date.

            (iii) If Pfizer has  declined  to  exercise  its right to terminate
      this Agreement under (x) Article 13.5(i)(c); and (y)  Article13.5(ii)(a),
      then, within ten (10) Business Days of the Adjustment Date,  Pfizer  will
      send  a  written  notice  to  that  effect  to Organon which notice shall
      identify  any amounts due as a result of the retroactive  application  of
      the adjustment  to the Parties' sharing of Development Costs set forth in
      subparagraph (ii)  above  (the  "Adjustment  Amount").   Within  ten (10)
      Business  Days  of  the date of such notice, Pfizer will pay Organon  the
      Adjustment Amount in accordance with the provisions of Article 9.5.

            (iv)  The Parties  have determined that the total Development Costs
      required  to obtain a Regulatory  Approval  for  a  Product  meeting  the
      Product  Profile   in   the   Major  Market  Countries  is  [CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED AND  FURNISHED  SEPARATELY TO THE SECURITIES
      AND EXCHANGE COMMISSION] (US$[CONFIDENTIAL INFORMATION  HAS  BEEN OMITTED
      AND FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION]) (the
      "Estimated Development Costs").  The Parties agree that either  Party may
      exceed the Estimated Development Costs by up to [CONFIDENTIAL INFORMATION
      HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE
      COMMISSION]  percent  ([CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED AND
      FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION]%) if such
      excess  expenditure  is necessary to comply with such Party's obligations
      under the then-current  Development  Plan, provided, however, that unless
      mutually agreed-upon by the Parties, neither  Party  shall be required to
      reimburse the other for any Development Costs incurred by the other Party
      in  excess  of [CONFIDENTIAL INFORMATION HAS BEEN OMITTED  AND  FURNISHED
      SEPARATELY  TO   THE   SECURITIES   AND   EXCHANGE   COMMISSION]  percent
      ([CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY  TO
      THE  SECURITIES  AND  EXCHANGE COMMISSION]%) of such Party's share of the
      Estimated Development Costs.

      4.5 Development of Improved Products. At the request of either Party, the
Parties  shall in good  faith  meet and  discuss  jointly  developing  Improved
Products where  preclinical  and/or clinical results provide a reasonable basis
for pursuing  such  additional  development  or the pursuit of such  additional
development is otherwise potentially  commercially  attractive.  If the Parties
agree to pursue  such  additional  development,  the  Parties  shall  amend the
Development  Plan  accordingly.  If the  Parties  do not agree to  pursue  such
additional development, then, neither Party shall have the right to pursue such
development  other  than  Organon's  right  to  pursue  development  of  a  New
Indication in accordance with Articles 4.6, 4.7 and 4.8.

      4.6 New  Indications.  With respect to  development of any New Indication
that the  Parties  do not agree to develop  jointly  pursuant  to Article  4.5,
Organon shall have the right to pursue the  development  of such New Indication
at its sole expense;  provided,  however, that (i) Organon's development of any
such New Indication would not, based on the best available scientific evidence,
be reasonably  likely to have a materially  adverse  effect on the Product then
being  Co-Promoted  by the  Parties;  and  (ii)  the  Product  for any such New
Indications is sold under a trademark or trademarks other than the Trademark(s)
(unless prohibited by the FDA or other Regulatory Authority,  in which case the
Trademark(s) may be used) and is developed and sold in a formulation and dosage
strength that does not create a reasonable  potential that the Product for such
New Indication  could be substituted by  prescribers,  dispensers  and/or Third
Party  payers  for  any  Product   being   Co-Promoted   by  the  Parties  (the
"Substitution  Product").  For the avoidance of doubt,  it is  understood  that
"reasonable potential" may include situations where the Substitution Product is
marketed,  promoted,  distributed  or sold  for use  other


                                       26




than for use in the Initial  Indications  (or any other  indication  then being
Co-Promoted  by  the  Parties),   utilizing  a  different  trademark  from  the
Trademark(s),  and  where  the  Substitution  Product  is  labeled  for  use in
indications  that are solely  outside the field of  psychiatric  disorders.  In
furtherance of, but without otherwise limiting Organon's  obligations  pursuant
to this Article 4.6, Organon  covenants and agrees that during the Term in each
Country  in the  Territory,  Organon  shall  not,  and  shall  ensure  that its
Affiliates and licensees  shall not,  market,  promote,  distribute or sell any
Product for a New Indication in a  [CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED
AND  FURNISHED  SEPARATELY  TO  THE  SECURITIES  AND  EXCHANGE  COMMISSION]  or
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES  AND  EXCHANGE   COMMISSION]   formulation   with  a   [CONFIDENTIAL
INFORMATION  HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO THE  SECURITIES  AND
EXCHANGE  COMMISSION]  mg,  [CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED  AND
FURNISHED   SEPARATELY  TO  THE   SECURITIES  AND  EXCHANGE   COMMISSION]   mg,
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES AND EXCHANGE  COMMISSION]  mg,  [CONFIDENTIAL  INFORMATION  HAS BEEN
OMITTED AND FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION] mg,
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES AND EXCHANGE  COMMISSION] mg or  [CONFIDENTIAL  INFORMATION HAS BEEN
OMITTED AND FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION] mg
dosage strength.

      4.7 Pfizer Opt-In Right. Subject to Article 4.8, if Organon or any of its
Affiliates intends to directly or indirectly, market,  sell, detail, promote or
distribute the Product for a New Indication in any Country  in the Territory at
any  time during the applicable Term, then, Organon shall provide  Pfizer  with
notice  to that effect (the "Opt-In Notice") within:  (x) sixty (60) days after
filing by  Organon  or  any  of  its  Affiliates  of  the  first  NDA  or other
Application  for Regulatory Approval for such New Indication with FDA or  other
Regulatory  Authority,  as  applicable;  or  (y)  sixty  (60)  days  after  the
acquisition  by   Organon   or  any  of  its  Affiliates,  whether  by  merger,
acquisition, license, or other  similar  transaction,  of  the  rights  to  the
Product  for  a  New  Indication  for  which  an  NDA  or other Application for
Regulatory Approval, as applicable, has already been filed  with or approved by
the  FDA or other Regulatory Authority.  Such Opt-In Notice shall  include  the
Supporting Information with respect to the New Indication as well as a detailed
statement  of  the  New  Indication  Development  Costs.  Pfizer shall have the
option, exercisable at its sole discretion, but in  no  event later than ninety
(90) days after Pfizer's receipt of the Opt-In Notice to notify Organon whether
Pfizer  elects  to  Co-Promote  such  New Indication with Organon  in  the  Co-
Promotion Countries (the "Election Notice").   If  Pfizer  elects to Co-Promote
such New Indication with Organon in the Co-Promotion Countries:

            (i)   then Pfizer shall pay Organon [CONFIDENTIAL  INFORMATION  HAS
      BEEN  OMITTED  AND  FURNISHED  SEPARATELY  TO THE SECURITIES AND EXCHANGE
      COMMISSION]  percent  ([CONFIDENTIAL INFORMATION  HAS  BEEN  OMITTED  AND
      FURNISHED SEPARATELY TO  THE SECURITIES AND EXCHANGE COMMISSION]%) of the
      New Indication Development  Costs  for such New Indication as of the date
      of  the Opt-In Notice in two (2) equal  installments,  the  first  within
      thirty  (30)  days  of  Organon's receipt of the Election Notice, and the
      second within 12-months after payment of the first installment; and

            (ii)  such  New Indication  shall  be  deemed  a  Product  for  all
      purposes under this  Agreement  and  Co-Promoted under the same terms and
      conditions as the Current Product.

      4.8 Sales for New Indications. If Pfizer does not elect to Co-Promote the
Product for a particular New Indication with Organon pursuant to Article 4.5 or
Article 4.7, and Organon Launches the Product  for  such  New  Indication  in a
Country  in  the Territory, Organon acknowledges that Launch of the Product for
such New Indication  may  require  that  the  Parties  distinguish sales of the
Product  for  such  New Indication from sales of the Product  for  the  Initial
Indications (or any other  indication  for  which  the  Parties  are  then  Co-
Promoting  the  Product).   In  order  to  allow  for  such  distinction  where
necessary, after


                                       27




the  Effective  Date but prior to the Launch in the  Territory of the first New
Indication,  the Parties will  mutually  agree upon a Third Party vendor (e.g.,
IMS, Verispan,  etc.) which Third Party vendor shall periodically,  but no less
often than calendar monthly,  measure, as accurately as is reasonably possible,
in accordance  with Schedule 4.8, sales of the Product in the Territory for New
Indications.  The  agreement  as to such Third Party shall not be  unreasonably
withheld or delayed by either  Party and the Third Party named in Schedule  4.8
is  hereby  deemed  approved  by both  Parties.  For  purposes  of  calculating
Organon's  payments to Pfizer pursuant to Article 9.1, Net Sales of the Product
will be reduced by the  percentage of Product sales reported for the applicable
accounting  period by such Third  Party  vendor as  representing  sales for New
Indications  not being  Co-Promoted by the Parties.  The  determination  of the
Third  Party as to the  sales  for any such New  Indication  shall be final and
binding on the  Parties,  absent  manifest  error,  and shall not be subject to
audit under this  Agreement.  If due to changes  made by Third  Party  vendors,
available information,  or other unforeseen circumstances,  the methodology set
forth on Schedule 4.8 cannot be employed by the Parties, then the Parties shall
mutually  agree  upon  the use of an  alternative  vendor  or  methodology,  as
applicable,  in order to accomplish the purpose described in this Article,  and
neither  Party will  unreasonably  withhold or delay its  agreement to any such
alternative.

      4.9 If the  Parties do not agree to jointly  develop  the  Product  for a
specific New Indication  pursuant to Article 4.5 and Pfizer does not thereafter
elect to Co-Promote the Product with Organon for such New  Indication  pursuant
to Article 4.7,  then,  effective  as of such time as Pfizer  elects not to Co-
Promote the Product for the specific New Indication in accordance  with Article
4.7 (the "Organon-Only  Product"),  such Organon-Only  Product will be excluded
from the  definition  of  "Product"  hereunder  (other than with respect to the
calculation  of payments  owed to Pfizer  pursuant to Article 9.1 as  described
above in Article 4.8 and other than with respect to the  applicable  provisions
necessary  for  purposes of such  calculation  including,  without  limitation,
Article 8A).

                                   ARTICLE 5

                           MANUFACTURING AND SUPPLY

      5.1  Production  Agreements.  The  Parties  acknowledge  that on the date
hereof  each of them or  their  respective  Affiliates  are  entering  into the
Production  Agreements for, among other things,  the manufacture of Products in
accordance with the respective terms of the Production Agreements.

      5.2  Supply  Allocation.  At any time  following  Launch in more than one
Country,  in the event that (a) the GCC and MSC agree that the  availability of
the Product shall be insufficient whether due to a shortage of Intermediate, or
the  Compound or  otherwise,  to meet the  forecasted  need for Product for the
following Calendar Quarter as determined by the CCCs and aggregated by the GCC,
or (b)  availability  of Product is in fact  insufficient  to fill orders on an
ongoing basis, then the GCC and MSC shall confer to resolve such insufficiency.
In the event the GCC and MSC cannot resolve such insufficiency,  then (i) there
shall be no further Launches of Product in any Country until the  insufficiency
is eliminated,  (ii) to the extent the insufficiency continues, then all safety
stock and sampling in any Country where the Product is sold will be utilized in
sales  in such  Country,  and  (iii)  to the  extent  the  insufficiency  still
continues,  then  unless  otherwise  agreed,  the  available  Product  shall be
allocated to the  Countries  where the Product is sold in  proportion  with the
then-current forecasted sales for the Product in each such Country.

      5.3 [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY
TO THE  SECURITIES  AND  EXCHANGE  COMMISSION]  Plans.  The Parties  shall work
together to monitor future  requirements and the [CONFIDENTIAL  INFORMATION HAS
BEEN  OMITTED  AND  FURNISHED   SEPARATELY  TO  THE   SECURITIES  AND  EXCHANGE
COMMISSION]  capabilities  of  Organon  and  Pfizer to ensure  the  timely  and
adequate [CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY TO
THE SECURITIES AND EXCHANGE COMMISSION] of the Intermediate and the Product. In
order to help ensure  adequate  [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND
FURNISHED  SEPARATELY  TO  THE  SECURITIES  AND  EXCHANGE


                                       28




COMMISSION] of the  Intermediate  and the Product,  the Parties  shall,  within
ninety (90) days of the  Effective  Date,  agree upon the existing  development
plan for the  processes  for  [CONFIDENTIAL  INFORMATION  HAS BEEN  OMITTED AND
FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]  the Compound
and the  Product  for the initial  Launch of the  Product  (such  [CONFIDENTIAL
INFORMATION  HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO THE  SECURITIES  AND
EXCHANGE COMMISSION],  the "First Generation [CONFIDENTIAL INFORMATION HAS BEEN
OMITTED AND FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]",
and such plan, the "First Generation [CONFIDENTIAL INFORMATION HAS BEEN OMITTED
AND FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION] Plan"). The
First  Generation  [CONFIDENTIAL  INFORMATION  HAS BEEN  OMITTED AND  FURNISHED
SEPARATELY  TO THE  SECURITIES  AND  EXCHANGE  COMMISSION]  Plan will  include,
without limitation, all information required to support submission of the First
Generation [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
TO THE  SECURITIES  AND EXCHANGE  COMMISSION]  to the FDA and other  Regulatory
Authorities  in  accordance  with the timeline  agreed upon by the Parties.  In
addition,  the Parties  shall,  within one hundred and eighty (180) days of the
Effective  Date,  explore  options for a  commercially  viable and  technically
feasible alternative  [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED
SEPARATELY TO THE  SECURITIES  AND EXCHANGE  COMMISSION]  and then agree upon a
corresponding   [CONFIDENTIAL   INFORMATION  HAS  BEEN  OMITTED  AND  FURNISHED
SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION] plan for establishing an
improved,  or "second  generation,"  process for [CONFIDENTIAL  INFORMATION HAS
BEEN  OMITTED  AND  FURNISHED   SEPARATELY  TO  THE   SECURITIES  AND  EXCHANGE
COMMISSION] the Compound (such  [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND
FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION],  the "Second
Generation [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
TO THE  SECURITIES  AND  EXCHANGE  COMMISSION]",  and such  plan,  the  "Second
Generation [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
TO THE  SECURITIES  AND  EXCHANGE  COMMISSION]  Plan").  The Second  Generation
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES AND EXCHANGE  COMMISSION]  Plan will have, as one of its objectives,
the completion of work by the Parties,  as such work is allocated in the Second
Generation [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
TO THE  SECURITIES  AND EXCHANGE  COMMISSION]  Plan,  on the Second  Generation
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES AND EXCHANGE COMMISSION],  no later than the first date of an action
by  FDA  or  another  Regulatory  Authority  which  action  could  result  in a
Regulatory Approval for the Product. Each of the First Generation [CONFIDENTIAL
INFORMATION  HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO THE  SECURITIES  AND
EXCHANGE COMMISSION] Plan and the Second Generation  [CONFIDENTIAL  INFORMATION
HAS BEEN  OMITTED AND  FURNISHED  SEPARATELY  TO THE  SECURITIES  AND  EXCHANGE
COMMISSION] Plan shall allocate  responsibilities  for  accomplishing the tasks
set forth in such plan between  Pfizer and Organon,  and the Parties  shall use
all  reasonable and diligent  efforts to cooperate with each other,  including,
without  limitation,  sharing any of its Technical  Information  with the other
Party, in order to successfully  execute the applicable plan.  Without limiting
the foregoing,  either Party may, at its own expense, undertake additional work
on the [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO
THE SECURITIES AND EXCHANGE COMMISSION] for the Compound or the Product. If the
Parties successfully develop a Second Generation [CONFIDENTIAL  INFORMATION HAS
BEEN  OMITTED  AND  FURNISHED   SEPARATELY  TO  THE   SECURITIES  AND  EXCHANGE
COMMISSION]  that is  acceptable  to each Party,  then the Parties will discuss
sourcing  strategies  for  implementing  the  Second  Generation  [CONFIDENTIAL
INFORMATION  HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO THE  SECURITIES  AND
EXCHANGE  COMMISSION]  with the goals of (i) maintaining  consistency  with the
principles  set forth in the  Production  Agreements;  and (ii) arriving at the
most  cost-effective  [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED
SEPARATELY TO THE SECURITIES  AND EXCHANGE  COMMISSION]  reasonable  achievable
under the circumstances.


                                       29




      5.4 Capacity  Plans.  Promptly after the Effective Date, the MSC will (i)
develop a standard for measuring  Intermediate  and  Compound  capacity  at the
Parties'  (or  their  Affiliates' or subcontractors') manufacturing facilities,
and (ii) develop a plan  (the  "Capacity  Plan")  designed  to  ensure that the
capacity  of the manufacturing facilities at which Organon or Pfizer  or  their
respective   Affiliates   intends  to  manufacture  or  have  manufactured  the
Intermediate and the Compound  have  optimum capacity to meet the forecasts set
by the GCC and safety stocks agreed by  the  MSC.  Unless otherwise established
by the MSC, the following safety stocks will be  kept:   (a)  six (6) months of
Intermediate;  (b)  nine  (9)  months  of Compound; and (c) two (2)  months  of
Primary Packaged Product.  Pfizer or its  Affiliate  will own title to and will
keep the safety stocks of Intermediate, Compound and Primary  Packaged Product.
Pfizer  will  have  the  right  to  keep the safety stocks of Primary  Packaged
Product at a warehouse facility owned  or  leased by Organon or its Affiliates.
The  Capacity Plan will include timelines and  milestone  dates  by  which  the
Parties  must  establish  that  the Intermediate, Compound and Primary Packaged
Product can be manufactured at the  forecasted  scale.   Each  Party  shall  be
responsible   for   having   the   agreed-upon   capacity  installed  at  those
manufacturing  locations owned by such Party, its Affiliate  or  subcontractor,
provided, however,  that  the  Parties shall mutually agree upon investments in
capacity at [CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
TO THE SECURITIES AND EXCHANGE COMMISSION].   In  addition,  each  Party or its
Affiliate   will   be   responsible  for  securing  commercial  and/or  quality
agreements, as applicable,  for  raw  materials or services, as necessary under
the circumstances, in order for such Party  or  its  Affiliate to carry out its
obligations under the Production Agreements.

      5.5 Release Testing. Each Party will be responsible  for  release testing
and the release of the Product (or component thereof), for that portion  of the
supply chain for which such Party is responsible.

                                   ARTICLE 6

                               COMMERCIALIZATION

      6.1 Co-Promotion.  Upon obtaining  Regulatory Approval and Price Approval
in a  Co-Promotion  Country,  the  Parties  shall use  Commercially  Reasonable
Efforts to Launch and  Co-Promote the Product in such  Co-Promotion  Country in
accordance with the Global Marketing Plan and the applicable  Country Marketing
Plan.

      6.2 Detail Requirements.  Subject to Schedule 1.40 to this Agreement, the
Global Marketing Plan, and the applicable  Country  Marketing Plan, the Parties
will develop,  review and mutually  agree upon  appropriate  Detailing  efforts
regarding targets,  call frequency,  and other sales force deployment issues in
order to achieve sales  objectives  consistent with the forecasts  developed by
the GCC with input from the CCCs.  Such  efforts are to be reviewed and updated
by the Parties at least on an annual basis. Commencing with the first Launch of
the Product in the US Territory  until the second  anniversary  of such Launch,
Pfizer Sales  Representatives  in the US Territory will be instructed to Detail
the Product in the first or second  position to all  prescribers who are in the
top [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY TO THE
SECURITIES AND EXCHANGE COMMISSION] percent ([CONFIDENTIAL INFORMATION HAS BEEN
OMITTED AND FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]%)
of prescribers of antipsychotic drugs as determined by Pfizer,  through the use
of reputable third party data, consistent with the manner in which Pfizer makes
such  determinations  for its own similar  products  (the "High  Prescribers").
However,  during the initial  [CONFIDENTIAL  INFORMATION  HAS BEEN  OMITTED AND
FURNISHED  SEPARATELY TO THE  SECURITIES AND EXCHANGE  COMMISSION]  after first
Launch of the Product in the US  Territory,  such Pfizer Sales  Representatives
may be instructed to Detail the Product to such High  Prescribers  in the third
position  provided  that such  instructions  are based on  Pfizer's  reasonable
judgment  that  Detailing  the  Product in the third  position  would give such
Detail the greatest emphasis during the particular call.

      6.3 Marketing Costs. In each Co-Promotion Country during each Year of the
Term, Pfizer will be responsible for [CONFIDENTIAL INFORMATION HAS BEEN OMITTED
AND FURNISHED


                                       30




SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]  percent  ([CONFIDENTIAL
INFORMATION  HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO THE  SECURITIES  AND
EXCHANGE  COMMISSION]%) of the Marketing Costs, and Organon will be responsible
for [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY TO THE
SECURITIES AND EXCHANGE COMMISSION] percent ([CONFIDENTIAL INFORMATION HAS BEEN
OMITTED AND FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]%)
of the Marketing Costs. Such Marketing Costs shall be reflected in the Parties'
Quarterly  Marketing  Cost Reports  pursuant to Article  8A.1.  Pfizer shall be
solely  responsible for all Out-of-Pocket  Costs and other costs solely related
to the marketing and promotion of Product in any Pfizer Exclusive Country,  and
Organon  shall be solely  responsible  for all Out-of-  Pocket  Costs and other
costs solely  related to the  marketing and promotion of Product in any Organon
Exclusive  Country.  In  each  Co-Marketing   Country,   each  Party  shall  be
responsible for one hundred percent (100%) of its respective  Marketing  Costs.
Parties are only  responsible  for payments  related to those  Marketing  Costs
defined in the Global Marketing Plan or a Country  Marketing Plan, or otherwise
approved by the GCC or CCC. Unless otherwise agreed as a Consensus Matter, each
Party agrees that the Global  Marketing Plan and Country  Marketing Plans shall
require each Party to spend up to its share of the minimum  Marketing Costs (by
Country or region,  as applicable) as reflected on Schedule 6.3 plus the Excess
Marketing Expenditure  described in the next sentence.  Absent mutual agreement
of the Parties,  however, neither Party shall be responsible for (and shall not
be  reimbursed  by the other  Party for) any cost or expense  that  exceeds the
annual  budgeted  Marketing  Costs  for the  applicable  Country  by more  than
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES AND EXCHANGE COMMISSION] ([CONFIDENTIAL INFORMATION HAS BEEN OMITTED
AND FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]%)  percent
of such budgeted amounts (the "Excess Marketing Expenditure").

      6.4 Reduction of Detailing  Requirements and Marketing Costs in the Major
Market Countries.

            (i)   Each  of  Pfizer  and Organon shall have the right, upon  one
      hundred (180) days prior notice to the other Party given prior to the end
      of the second consecutive Year  described  below, to reduce its Detailing
      Requirements  in  the  Major  Market  Countries and  its  Marketing  Cost
      obligations if in any two consecutive Years  after  (a)  the  second Year
      after  the  Launch  of the Product in such Major Market Country, if  such
      Launch occurs on or before June 30 of the calendar year, or (b) the third
      Year after such Launch,  if  the  Launch  occurs  after  June  30  of the
      calendar  year,  Net Sales in any such Major Market Country are less than
      [CONFIDENTIAL INFORMATION  HAS  BEEN  OMITTED AND FURNISHED SEPARATELY TO
      THE   SECURITIES   AND   EXCHANGE  COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO THE SECURITIES
      AND  EXCHANGE  COMMISSION]%)  of  the  applicable  Major  Market  Country
      Forecast  for such Major Market Country;  provided  that  such  notifying
      Party is not  then  (i) in Material Default of its obligations under this
      Agreement, (ii) is not  a  Shortfall  Party in such Major Market Country,
      (iii) is not a Detail Breaching Party in  such  Major Market Country, and
      (iv)  there  is  no Force Majeure in such Major Market  Country  that  is
      continuing at such  time and provided further that such notice shall only
      be effective if such  percentage  is  not actually achieved by the end of
      the second consecutive Year. The notice provided to the other Party shall
      specify the amount in percentage terms  by  which it intends to so reduce
      its obligations.  In the event such notice provided  above  is given, the
      other Party shall be permitted to give notice, no later than  sixty  (60)
      days  prior  to  the  end  of  such  Year, of its intention to reduce its
      Detailing  and  Marketing  Cost  obligations,  which  notice  shall  also
      describe in percentage terms the amount by which it intends to reduce its
      Detailing and Marketing Cost obligations.  If  the  Net  Sales in a Major
      Market  Country  are  less than said [CONFIDENTIAL INFORMATION  HAS  BEEN
      OMITTED  AND  FURNISHED  SEPARATELY   TO   THE  SECURITIES  AND  EXCHANGE
      COMMISSION]  percent  ([CONFIDENTIAL INFORMATION  HAS  BEEN  OMITTED  AND
      FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION]%) in such
      second  consecutive Year,  each  Party's  Detailing  and  Marketing  Cost
      obligations in each subsequent Year in such Major Market Country shall be
      reduced by  the


                                       31




      amount  corresponding to the percentage specified in such Party's notice,
      but in no event shall either Party's  respective  Detailing and Marketing
      Cost  obligations  be  reduced  below  the  product  of (a) such  Party's
      Detailing  Requirement and Marketing Cost  obligations  applicable  under
      this  Agreement for the then current Year,  without giving effect to this
      Article  6.4(i),  and (b) a fraction,  the numerator of which is the mean
      average  Net Sales for such  Country  during  the two  consecutive  Years
      referred to in the first  sentence,  and the  denominator of which is the
      mean average Major Market  Country  forecast for such Country during such
      Years, as illustrated on Schedule 6.4.

            (ii)  Other Readjustments  in  the  Major Market Countries.  In the
      event  Net  Sales  in  any  Major  Market  Country   shall   be   between
      [CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND FURNISHED SEPARATELY  TO
      THE SECURITIES AND EXCHANGE COMMISSION]%  and  [CONFIDENTIAL  INFORMATION
      HAS BEEN OMITTED AND FURNISHED SEPARATELY TO THE SECURITIES AND  EXCHANGE
      COMMISSION]%  of  the Major Market Country Forecast for such Major Market
      Country, either Party  shall have the right to initiate discussions as to
      the appropriate readjustment  in  the terms of such Party's participation
      in  commercialization in such Major  Market  Country;  provided,  however
      (a) mutual  agreement  of  the  Parties  will  be  required  to  make any
      amendments  or  adjustments  to  the terms of this Agreement; and (b)  no
      Party shall have any obligation of  any  kind to make any such amendments
      or adjustments or in connection with failing  to make any such amendments
      or adjustments.

            (iii) Adjustments for Detailing Requirements and Marketing Costs in
      Other Co-Promote Countries.  Each of Pfizer and  Organon  shall  have the
      right,  provided  such  Party  is  not  then  in  Material Default of its
      obligations under this Agreement and is not a Shortfall Party or a Detail
      Breaching  Party, and there is no Force Majeure which  is  continuing  at
      such time, upon  ninety  (90)  days prior notice to the other Party given
      prior to the end of such Year described  below,  on  a Country-by-Country
      basis with respect to all Co-Promotion Countries, other than Major Market
      Countries ("Other Countries"), to reduce its Detailing  Requirements  and
      the  amount  of Marketing Costs as provided in this Article 6.4.  In each
      Other Country, the adjustment will only become effective after the end of
      the third full  Year  after  Launch,  and  the procedure set forth herein
      shall be applied for each subsequent Year (starting  with the Fifth Year)
      until expiration of the Term for each such Other Country:

                  (a) For the first eight months during each  Year  (January  1
            through August  31)  the  Net Product Sales during such eight month
            period ("8 Month Sales") will be determined and compared to the Net
            Sales forecast for such period   ("8  Month Forecast") as set forth
            in the applicable Country Marketing Plan.  If the 8 Month Sales are
            less than [CONFIDENTIAL INFORMATION HAS  BEEN OMITTED AND FURNISHED
            SEPARATELY  TO  THE  SECURITIES  AND EXCHANGE  COMMISSION]  percent
            ([CONFIDENTIAL   INFORMATION  HAS  BEEN   OMITTED   AND   FURNISHED
            SEPARATELY TO THE  SECURITIES  AND  EXCHANGE COMMISSION]%) of the 8
            Month Forecast, then the ratio ("Ratio")  shall  be  determined  by
            dividing  the  8  Month  Sales  by  the  8  Month Forecast, and the
            resulting  Ratio  shall  be  used (as specified in  subsection  (b)
            below) to determine the Detailing  Requirements  and  the amount of
            Marketing Costs for the following Year.

                  (b) To determine the Detailing Requirements and the amount of
            Marketing  Costs,  the  then  applicable Detailing Requirement  and
            Marketing Cost number would be  multiplied  by  the  Ratio, and the
            result  would  be  the  Detailing  Requirement  and Marketing  Cost
            obligations for the following Year.

      6.5 Co-Promotion  Resources.  It is the intention of Organon  and  Pfizer
that, during the Term in each Co-Promotion  Country, each of Organon and Pfizer
will devote adequate resources to the Co-Promotion  of  the  Product in the Co-
Promotion  Countries  and  to  otherwise discharge its obligations


                                       32




under this Agreement. If Organon and Pfizer agree that one Party should provide
more than [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY
TO THE SECURITIES AND EXCHANGE COMMISSION] percent  ([CONFIDENTIAL  INFORMATION
HAS BEEN  OMITTED AND  FURNISHED  SEPARATELY  TO THE  SECURITIES  AND  EXCHANGE
COMMISSION]%)  of  the  Details  in a  Co-Promotion  Country,  whether  because
additional Detailing is necessary beyond that contemplated in this Agreement or
otherwise, or one Party is requested to devote other resources in excess of its
appropriate  share, the Parties shall first determine fair compensation to such
Party for its additional efforts. Without limiting the foregoing, other than as
set forth in Article  6.5A below  with  respect to each of the United  Kingdom,
Spain,  Germany,  France  and  Canada,  each  Party  must  be  willing,  in the
applicable   Country   Marketing   Plan,  to  undertake  to  perform  at  least
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES AND EXCHANGE COMMISSION] percent ([CONFIDENTIAL INFORMATION HAS BEEN
OMITTED AND FURNISHED  SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION]%)
of the total Product Details in each  Co-Promotion  Country in each Year of the
applicable  Term (the  "Minimum  Detail  Percentage").  Subject to Article 2.5,
Organon  may engage a  contract  sales  force in Japan in order to satisfy  the
Minimum Detail Percentage, and Pfizer's consent to such engagement shall not be
unreasonably  withheld.  If either  Party  (the  "Nonperforming  Party") is not
willing to undertake to perform the Minimum Detail Percentage in a Co-Promotion
Country in any Year,  then (i) if Pfizer is the  Nonperforming  Party,  Organon
shall have the right to  terminate  this  Agreement  pursuant  to Article  13.3
solely with respect to such  Co-Promotion  Country;  and (ii) if Organon is the
Nonperforming  Party,  Pfizer shall have the right to convert such Co-Promotion
Country from a Co- Promotion Country to a Pfizer Exclusive Country.

      6.5A Co-Promotion in Canada and Certain Key EU Countries.

            (i)   Notwithstanding  the  provisions  of  Article  6.5 above, the
      Parties agree that, the Minimum Detail Percentage shall not apply in each
      of  the  United  Kingdom, Spain, Germany, France and Canada (the  "Big  5
      Countries").  In each  of  the  Big 5 Countries, the applicable CCC shall
      determine each Party's Detail Requirement  for each Year of the Term, and
      each Party shall have the right to perform [CONFIDENTIAL  INFORMATION HAS
      BEEN  OMITTED  AND  FURNISHED  SEPARATELY TO THE SECURITIES AND  EXCHANGE
      COMMISSION]  percent ([CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED  AND
      FURNISHED SEPARATELY  TO THE SECURITIES AND EXCHANGE COMMISSION]%) of the
      Details in each such Country  in  each  Year.   If either Party (the "Low
      Detailing Party") elects to perform fewer than [CONFIDENTIAL  INFORMATION
      HAS BEEN OMITTED AND FURNISHED SEPARATELY TO THE SECURITIES AND  EXCHANGE
      COMMISSION]  percent  ([CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED AND
      FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION]%)  of the
      total Details determined by the CCC to be warranted in one or more of the
      Big  5  Countries  in any Year, then (a) the other Party may, in its sole
      discretion, elect to perform the Details that the Low Detailing Party was
      not able to perform;  and  (b) the Low Detailing Party's share of the Net
      Sales of the Product in such  Country  for  such Year shall be reduced by
      applying the following formula:

      N  =  P  -  [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED  AND  FURNISHED
      SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION] - R)

      N = The Low Detailing Party's new Net Sales share under this Agreement

      P  =  The  Low  Detailing  Party's original Net Sales  share  under  this
      Agreement  (i.e.,  for Organon,   P=[CONFIDENTIAL  INFORMATION  HAS  BEEN
      OMITTED  AND  FURNISHED   SEPARATELY   TO  THE  SECURITIES  AND  EXCHANGE
      COMMISSION] and for Pfizer, P=[CONFIDENTIAL  INFORMATION HAS BEEN OMITTED
      AND FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION])


                                       33




      R = the fraction (expressed as a percentage) the  numerator  of  which is
      number  of Details that the Low Detailing Party has agreed to perform  in
      such Country  in  the applicable Year and the denominator of which is the
      total Details agreed  to  be  performed by the Parties in such Country in
      the applicable Year.

      6.6 Co-Marketing.

            (i)   In the event the Parties are legally unable to Co-Promote the
      Product in a particular Co-Promotion  Country  in  which they are both in
      agreement  that the Product should be commercialized,  the  Parties  will
      endeavor to  decide  whether  such  Country  will  be  a Pfizer Exclusive
      Country  or  an  Organon  Exclusive  Country.   In  the absence  of  such
      agreement,  the  Parties  will  be  entitled  to  Co-Market  the  Product
      independently in the Country.  For the Co-Marketing Countries, Pfizer and
      Organon  shall  each  have access to all Promotional Materials  developed
      jointly by the Parties.  If a single Trademark is used for the Product in
      the Co-Promotion Countries,  Organon  shall  have  the  right to use such
      Trademark  in  the Co-Marketing Countries.  Each Party shall  market  the
      Product in a manner  substantially consistent with the general strategies
      expressed in the Global  Marketing  Plan,  but shall otherwise be free to
      market the Product in such Co-Marketing Country  as  it deems appropriate
      in its sole discretion.  Organon and Pfizer shall each  bear  all  of its
      own  costs  and  expenses in advertising and promoting the Product in the
      Co-Marketing Countries.   Each Party shall retain all revenues accrued by
      such Party (or its relevant  local Affiliate) on its sales of any Product
      in each Co-Marketing Country.   Within  sixty (60) days following the end
      of each Calendar Quarter following Product  Launch  in  any  Co-Marketing
      Country, each Party shall provide the JOC with a detailed report  of  Net
      Sales made by the Party or its local Affiliate in Co-Marketing Countries.
      The format of such reports shall be mutually agreed-upon by the JOC.

            (ii)  In the event that the Parties mutually agree to convert a Co-
      Marketing Country to a Pfizer Exclusive Country, Pfizer shall pay Organon
      a  royalty  of  [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED
      SEPARATELY   TO   THE  SECURITIES  AND   EXCHANGE   COMMISSION]   percent
      ([CONFIDENTIAL INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE SECURITIES AND EXCHANGE COMMISSION]%)  of  Net Sales in such Country,
      in lieu of the [CONFIDENTIAL INFORMATION HAS BEEN  OMITTED  AND FURNISHED
      SEPARATELY   TO   THE   SECURITIES   AND   EXCHANGE  COMMISSION]  percent
      ([CONFIDENTIAL INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO
      THE SECURITIES AND EXCHANGE COMMISSION]%) royalty set  forth  in  Article
      9.2.   Such  [CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED AND FURNISHED
      SEPARATELY   TO   THE   SECURITIES   AND  EXCHANGE  COMMISSION]   percent
      ([CONFIDENTIAL INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO
      THE  SECURITIES AND EXCHANGE COMMISSION]%) royalty shall  be  subject  to
      adjustment pursuant to Articles 9.2(i) and 9.2(ii).

      6.7 Exclusive Countries. Pfizer and Organon shall each have access to all
Promotional  Materials  developed  jointly  by the Parties for the Co-Promotion
Countries and shall bear all of its own costs  and  expenses in advertising and
promoting  the  Product  in  the  Pfizer Exclusive Countries  and  the  Organon
Exclusive Countries, respectively.   In  the Pfizer Exclusive Countries and the
Organon Exclusive Countries, each of Pfizer  and  Organon, as applicable, shall
conduct  its  business  consistent  with  the  Global Marketing  Plan  and  the
Development Plan.

      6.8 Conversion of Countries

            (i)   Initial  Conversion  from  Co-Promotion   Country  to  Pfizer
      Exclusive  Country.   As soon as is practicable following  the  Effective
      Date but in no event later than  November 15, 2004, Organon shall provide
      Pfizer with a list of each Co-Promotion Country in which Organon does not
      intend to Co-Promote the  Product  with Pfizer.  Upon Pfizer's receipt of
      such  notice,  the


                                       34




      Co-Promotion Country or Co-Promotion  Countries identified in such notice
      shall be designated a Pfizer Exclusive Country.

            (ii)  Conversion  from a Pfizer Exclusive Country to a Co-Promotion
      Country or Co-Marketing Country.

                  (a)  Notwithstanding  anything to the  contrary  contained in
            this   Agreement,   if  Organon  can   demonstrate  to  Pfizer  the
            Co-Promotion  Criteria for a Pfizer Exclusive Country,  then at any
            time from the  Effective  Date  through  and  including  the period
            ending  three (3)  years  from the date of  Product  Launch in such
            Pfizer Exclusive Country, Organon may elect, upon not less than one
            hundred eighty (180) days written notice to Pfizer,  to convert any
            Pfizer  Exclusive  Country  to a  Co-Promotion  Country  or, if the
            applicable Law in such Country does not permit the conversion  into
            a Co- Promotion Country, to a Co-Marketing Country.  During the one
            hundred eighty (180) days following the receipt of Organon's notice
            of election, the Parties shall undertake the development of a joint
            marketing  plan for such  Country.  Any  such  conversion  shall be
            effective  as of the  close of  business  on the date  which is one
            hundred  eighty  (180)  days  from  the  date of such  notice  (the
            "Conversion Date").

                  (b) In the event that  Organon is unable to  demonstrate  its
            ability to conduct a Co-Promotion in any Co-Promotion Country, that
            Country  shall  continue  to be  designated  as a Pfizer  Exclusive
            Country.

                  (c) The Parties  agree to amend  Schedule 1.33 to reflect the
            updated list of Co-Promotion Countries, respectively.

            (iii) If  a  Pfizer Exclusive  Country  is  converted  into  a  Co-
      Promotion Country within  three  (3)  years  of  Product  Launch  in such
      Country, then no later than two (2) months prior to the Conversion  Date,
      Pfizer  shall  deliver  to  Organon a statement (the "Interim Statement")
      setting forth, in reasonable  detail  (a)  itemized Development Costs and
      Marketing Costs attributable to such Country  ("Exclusive Country Costs")
      for  the Product for all periods ending three (3)  months  prior  to  the
      Conversion Date, and (b) Pfizer's Net Sales of the Product in the Country
      for the nine (9) month period ending on the date that is three (3) months
      prior to the Conversion Date.  Organon shall pay to Pfizer, within thirty
      (30) days  following receipt of the Interim Statement, an amount equal to
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE   SECURITIES   AND   EXCHANGE  COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO THE SECURITIES
      AND  EXCHANGE  COMMISSION]%)  of  the  Exclusive   Country   Costs,   and
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE   SECURITIES   AND   EXCHANGE  COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO THE SECURITIES
      AND EXCHANGE COMMISSION]%) of the foregoing  Net  Sales  (if applicable),
      all  as shown on the Interim Statement.  No later than thirty  (30)  days
      following  the  Conversion  Date,  Pfizer  shall  deliver  to  Organon  a
      statement  (the "Conversion Date Statement") setting forth, in reasonable
      detail, Exclusive  Country  Costs  for  the  Product during the three (3)
      month period ending on and including the Conversion Date and Pfizer's Net
      Sales  of the Product in the Country (if any) for  the  three  (3)  month
      period ending  on  the  Conversion  Date.   Organon  shall pay to Pfizer,
      within  thirty  (30)  days  following  receipt  of  the  Conversion  Date
      Statement, an amount equal to [CONFIDENTIAL INFORMATION HAS  BEEN OMITTED
      AND  FURNISHED  SEPARATELY  TO  THE  SECURITIES  AND EXCHANGE COMMISSION]
      percent  ([CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED   AND  FURNISHED
      SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION]%) of the  Exclusive
      Country   Costs  and  [CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED  AND
      FURNISHED SEPARATELY  TO  THE SECURITIES AND EXCHANGE COMMISSION] percent
      ([CONFIDENTIAL INFORMATION  HAS  BEEN


                                       35

      COMMISSION]%)  of the Net  Sales  (if  applicable),  all as  shown on the
      Conversion Date Statement.

            (iv)  Beginning on the Conversion Date, Products  in the applicable
      Country  shall  be  treated  as  a  Product  in  a  Co-Promotion Country;
      provided, however, that for a reasonable transition period  of  up to one
      hundred  and  eighty (180) days, Pfizer shall be entitled to continue  to
      purchase Product  and  book  sales  thereof  but  shall  then pay Organon
      [CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND FURNISHED SEPARATELY  TO
      THE   SECURITIES   AND   EXCHANGE  COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED  AND  FURNISHED SEPARATELY TO THE SECURITIES
      AND EXCHANGE COMMISSION]%) of such Net Sales as a Co-Promotion fee during
      such transition period, in lieu of any royalty payments due under Article
      9.2.   In the event that Organon's local  Affiliate  is  not  capable  of
      booking  sales of the Product in a particular Co-Promotion Country by the
      end of such  transition  period, then the local Pfizer Affiliate shall be
      entitled to continue book such sales.

            (v)   If  a  Pfizer Exclusive  Country  is  converted  into  a  Co-
      Marketing Country, then,  no  later  than  two  (2)  months  prior to the
      Conversion  Date,  Pfizer  shall  deliver to Organon an Interim Statement
      setting forth, in reasonable detail,  Exclusive  Country  Costs  for  the
      Product  for  all periods ending three (3) months prior to the Conversion
      Date, all Internal Costs incurred by Pfizer in relation to the Country in
      question directly related to complying with the registration requirements
      of the Country  for  the  Product for all periods ending three (3) months
      prior  to  the  Conversion  Date  ("Internal  Registration  Costs"),  and
      Pfizer's Net Sales of the Product  in  the Country for the nine (9) month
      period  ending  on  the  date  that is three  (3)  months  prior  to  the
      Conversion Date. Organon shall pay  to  Pfizer,  within  thirty (30) days
      following  the  receipt  of  the  Interim  Statement  an amount equal  to
      [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY  TO
      THE   SECURITIES  AND   EXCHANGE   COMMISSION]   percent   ([CONFIDENTIAL
      INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO THE SECURITIES
      AND  EXCHANGE  COMMISSION]%)   of   such   Internal  Registration  Costs,

      THE   SECURITIES   AND   EXCHANGE   COMMISSION]   percent  ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY  TO  THE SECURITIES
      AND   EXCHANGE   COMMISSION]%)   of  such  Exclusive  Country  Costs  and

      THE   SECURITIES   AND   EXCHANGE   COMMISSION]   percent  ([CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY  TO  THE SECURITIES
      AND  EXCHANGE  COMMISSION]%)  of  Net Sales, all as shown on the  Interim
      Statement. No later than thirty (30)  days following the Conversion Date,
      Pfizer  shall  deliver  to Organon a Conversion  Date  Statement  setting
      forth,  in detail, Exclusive  Country  Costs  for  the  Product  and  all
      Internal Registration Costs incurred by Pfizer in relation to the Country
      in question during the three (3) month period ending on and including the
      Conversion  Date and Pfizer's Net Sales of the Product in the Country for
      the three (3)  month  period ending on the Conversion Date. Organon shall
      pay to Pfizer, within thirty  (30)  days  following  the  receipt  of the
      Conversion  Date  Statement, an amount equal to [CONFIDENTIAL INFORMATION
      HAS BEEN OMITTED AND  FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE
      COMMISSION]  percent ([CONFIDENTIAL  INFORMATION  HAS  BEEN  OMITTED  AND

      COMMISSION]%)  of  Net  Sales,  all  as  shown  on  the  Conversion  Date
      Statement.  The license  granted by Organon to Pfizer pursuant to Article
      2.1 will remain  applicable  with  respect to such  Country,  any and all
      ongoing  Development  Costs shall be shared by the Parties in  accordance
      with Article 4.4, and Marketing Costs shall be borne independently by the
      Parties.

            (vi)  In the event that each Party is required  by  Law  to operate
      through  a local distributor in a Co-Promotion Country then such  Country
      shall  remain   a  Co-Promotion  Country;  provided,  however,  that  the
      distributor for the  Product in such Country shall be selected (x) by the
      Party that maintains management  services in such Country through its own
      employees, or (y) if both Parties  maintain  management  services in such
      Country then as mutually agreed to by the Parties.

            (vii) Conversion to Organon Exclusive Country.  If Pfizer  (a) does
      not  file  for  Regulatory  Approval in a Pfizer Exclusive Country within
      [CONFIDENTIAL INFORMATION HAS  BEEN  OMITTED  AND FURNISHED SEPARATELY TO
      THE SECURITIES AND EXCHANGE COMMISSION] after Launch  of  the  Product in
      the  US  Territory  (or,  if Regulatory Approval in such Pfizer Exclusive
      Country  requires  that the Product  receive  Regulatory  Approval  in  a
      particular Country other  than  the  US Territory, such as the Country of
      manufacture of the Product or a Key EU Country, then within [CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED AND FURNISHED  SEPARATELY  TO THE SECURITIES

      Launch  the Product in such Pfizer Exclusive Country within [CONFIDENTIAL
      INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO THE SECURITIES
      AND EXCHANGE COMMISSION] of receipt of both Regulatory Approval and Price
      Approval in such Country,  then  Organon  may  request,  and Pfizer shall
      agree, to convert such Country into an Organon Exclusive Country.  To the
      extent  that Pfizer has taken steps in such Country to obtain  Regulatory
      Approval,  Pfizer shall in such event, at Organon's sole expense, provide
      transitional  assistance  to  Organon as may be reasonably necessary with
      the Regulatory Authorities in the  relevant Country to facilitate Organon
      to obtain Regulatory Approvals in such Country.

      6.9 Detail Shortfalls

            (i)   In the event that either  Party fails to perform (such Party,
      a "Shortfall Party") at least [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED
      AND  FURNISHED  SEPARATELY  TO  THE SECURITIES AND  EXCHANGE  COMMISSION]

      Requirement  in any Year as reported pursuant to Article 8A.6 or verified
      pursuant to Article  8A.7  in  any  of  the  Major  Market Countries, the
      Shortfall  Party  shall pay to the other Party as liquidated  damages  an
      amount equal to the  Detail Cost, multiplied by the applicable factor set
      forth below (the "Shortfall  Factor")  multiplied  by the total number of
      Details in the shortfall (the Detail Cost, multiplied  by  the  number of
      Details in the shortfall, multiplied by the Shortfall Factor, the "Detail
      Shortfall Payment Amount"), on an incremental basis as set forth below:

For   purposes   of  this  Article  6.9,  "Detail  Cost"  for  the  U.S.  means
$[CONFIDENTIAL INFORMATION  HAS  BEEN  OMITTED  AND FURNISHED SEPARATELY TO THE
SECURITIES AND EXCHANGE COMMISSION], and Detail Cost for the other Major Market
Countries  means  $[CONFIDENTIAL  INFORMATION HAS BEEN  OMITTED  AND  FURNISHED
SEPARATELY TO THE SECURITIES AND EXCHANGE  COMMISSION].   If  a Party wishes to
verify the Details performed by the other Party in any Year, such  Party  shall
give  notice  to  the  other  Party  that  the notifying Party wishes to verify
Details pursuant to Article 8A.7 within forty-five  (45)  days after receipt of
the  other  Party's last Detailing Report set forth in Article  8A.6  for  such
Year.

            (ii)  With respect to any Year in which only one of the Parties was
      a Shortfall  Party,  the  Shortfall  Party  shall, within sixty (60) days
      after the end of such Year (or within thirty  (30)  days after completion
      of  any  verification(s)  of Details pursuant to Article  8A.7  conducted
      pursuant to Article 6.9(i)  for  such  Year, if such verification(s) have
      not been completed within thirty (30) days  after  the end of such Year),
      pay the Detail Shortfall Payment Amount to the other Party.

            (iii) With respect to any Year in which both Parties  are Shortfall
      Parties, the Party having performed the highest percentage of  its Detail
      Requirement in such Year (the "Highest Performing Party") shall be deemed
      not  to  be  a  Shortfall Party and the percentage of such Party's Detail
      Requirement performed  by such Party shall be deemed to equal one hundred
      percent


                                       38




      (100%) of that Party's  Detail  Requirement  in  such  Year.  The
      other  Party  shall  continue  to  be  required to pay a Detail Shortfall
      Payment  Amount in accordance with Article  6.9(ii);  provided,  however,
      such Detail Shortfall Payment Amount to be paid by such other Party shall
      be reduced  by  (a) multiplying such other Party's Detail Requirement for
      such Year by the  percentage  of  the  Highest  Performing Party's Detail
      Requirement  actually  performed by the Highest Performing  Party  during
      such Year, and (b) recalculating  such  other  Party's  Detail  Shortfall
      Payment Amount using the reduced Detail Requirement for such other  Party
      calculated in accordance with the immediately preceding clause (a).

            (iv)  In  the  event  that  either  Party fails to perform at least

      two (2) consecutive Years during the Term  in  such  Country  (a  "Detail
      Shortfall Period"), then:

                  (a) If  Pfizer is  the  Detail Breaching Party, Organon shall
            have the right, in addition to the remedies provided for in Article
            6.9(ii) and 6.9(iii) above, exercisable upon notice to Pfizer given
            within  sixty (60) days after the  end  of  such  Detail  Shortfall
            Period  (or  within  thirty  (30)  days  after  completion  of  any
            verification of Pfizer's Details pursuant to Article 8A.7 conducted
            at Organon's  request  pursuant  to  Article 6.9(i) for such Detail
            Shortfall  Period,  if such verification  has  not  been  completed
            within thirty (30) days  after  the  end  of  such Detail Shortfall
            Period), such notice to be effective sixty (60) days after the date
            of such notice to Pfizer (or thirty (30) days after  completion  of
            any  verification  of  Pfizer's  Details  for such Detail Shortfall
            Period  requested  by  Organon,  if later), to  terminate  Pfizer's
            rights  under  this  Agreement  with respect  to  the  Co-Promotion
            Countries  in  which  such  Detail  Shortfall  has  occurred.   For
            purposes of this Agreement, such termination  shall be treated as a
            termination pursuant to Article 13.3; and

                  (b) If  Organon  is the Detail Breaching Party, Pfizer  shall
            have the right, in addition to the remedies provided for in Article
            6.9(ii) and 6.9(iii) above,  exercisable  upon  notice  to  Organon
            given within sixty (60) days after the end of such Detail Shortfall
            Period  (or  within  thirty  (30)  days  after  completion  of  any
            verification   of   Organon's  Details  pursuant  to  Article  8A.7
            conducted at Pfizer's  request  pursuant to Article 6.9(i) for such
            Detail  Shortfall  Period,  if  such   verification  has  not  been
            completed within thirty (30) days after  the  end  of  such  Detail
            Shortfall  Period),  such  notice  to  be effective sixty (60) days
            after the date of such notice to Organon (or thirty (30) days after
            completion of any verification of Organon's Details for such Detail
            Shortfall Period requested by Pfizer, if later), to convert the Co-
            Promotion Country(ies) in which such Detail  Shortfall has occurred
            from a Co-Promotion Country to a Pfizer Exclusive Country.

            (v)   The  Parties understand and agree that the  Detail  Shortfall
      Payment Amount shall  be  paid as liquidated damages and not as a penalty
      and that such sum represents  a  pre-estimate  of  the  loss  the Parties
      believe would be suffered as a result of Detail shortfalls.  In the event
      of  any Detail shortfall under Article 6.9, the remedies and compensation
      as provided herein shall govern, and neither Party shall have any further
      claim for breach of this Agreement on account of such Detail shortfall.

      Competing  Product in such Country  without the prior written  consent of
      the other Party.

            (ii)  Notwithstanding the foregoing, it  is  understood  and agreed
      that  the  non-compete restriction set forth in Article 6.10(i) does  not
      prohibit either  Party  or  their  Affiliates from marketing or selling a
      Competing  Product  (a  "De  minimis  Product")   where  such  Party  has
      (a) acquired  a  business  from  a  Third  Party  as  part  of  a  larger
      transaction where the business has a Competing Product,  or  (b)  entered
      into a merger or other business combination with a Third Party, where the
      Third  Party has a Competing Product, in each of (a) and (b) above,  only
      if the sales  of  the Competing Product represent less than [CONFIDENTIAL

      transaction),  and  provided further that sales in such twelve (12) month
      period of the Competing  Product,  as the sales of such Competing Product
      are  reported by IMS, do not exceed USD  $[CONFIDENTIAL  INFORMATION  HAS

                              REGULATORY MATTERS

      7.1.  Regulatory Matters in Co-Marketing  Countries.   The  Parties shall
cause  the  development  of  the  Product in the Co-Marketing Countries  to  be
conducted in a manner allowing Pfizer  and  Organon  to  each secure Regulatory
Approvals for the Product issued contemporaneously and under the same terms and
conditions,  including  without limitation maintaining bio-equivalence  of  the
Parties' respective Products.

      7.2.  Regulatory Matters in the Co-Promotion Countries.  This Article 7.2
shall apply to regulatory  matters  relating to the Product in the Co-Promotion
Countries.

            (i)   All  NDAs and other  Applications  for  Regulatory  Approvals
      within the Co-Promotion  Countries  relating  to the Product shall be the
      property  of Organon and held in the name of Organon  or  its  designated
      Affiliates.   Organon's  designated  representative  shall  serve  as the
      designated  regulatory official for Product in the Co-Promotion Countries
      for purposes  of  receiving  communications  from Regulatory Authorities.
      Notwithstanding the foregoing, each Party will  have  the exclusive right
      to and will be responsible for interacting with Regulatory Authorities on
      matters concerning each Party's manufacturing site(s) that  are  involved
      in  the manufacture of the Intermediate, Compound or the Product pursuant
      to the  Alliance  Agreements.   In the event that applicable Law requires
      that Organon respond to a Regulatory Authority in the Territory on behalf
      of Pfizer, then Organon may do so  provided,  however,  that  Pfizer  and
      Organon   mutually   agree  on  Organon's  response  to  such  Regulatory
      Authority.

            (ii)  Organon will  provide Pfizer with copies, which copies may be
      in  draft  form, of all substantive  submissions  (subject  to  the  last
      sentence of  this  Article 7.2(ii)) to Regulatory Authorities through the
      CDRC. Organon will provide  Pfizer  with such copies at least twenty (20)
      Business Days prior to planned submission  to the FDA or other Regulatory
      Authority by Organon,


                                       40




      whereupon  Pfizer  shall  provide  comments  to  Organon  regarding  such
      submission at least ten (10) days prior to such planned submission,  and,
      subject to the  determination of the CDRC,  Organon shall incorporate the
      comments given by Pfizer prior to making such submission. With respect to
      any NDA,  supplemental NDA, or other Application for Regulatory Approval,
      the CDRC (and, with respect to the Chemistry,  Manufacturing and Controls
      ("CMC") section of the NDA, and comparable sections in other Applications
      for  Regulatory  Approval in the Co- Promotion  Countries,  the MSC) will
      agree upon a separate  review  schedule in order to take into account the
      volume and scope of such submissions.

            (iii) Organon  shall  provide  notice  to  Pfizer  within  two  (2)
      Business Days of:  (a) discovery by Organon of any event that triggers an
      FDA (or other Regulatory Authority) filing requirement promptly after the
      discovery of such an event; and (b) any FDA requirements  which  FDA  may
      impose  with  respect  to  the  Regulatory  Approval,  (including without
      limitation,  additional  clinical  studies)  and  of  all FDA  (or  other
      Regulatory  Authority)  inquiries  requiring a response.   Organon  shall
      promptly provide copies of any correspondence,  and copies of all FDA (or
      other Regulatory Authority) contact reports produced by Organon, or other
      submission   relating   to  this  Article  7.2(iii)   to   the   Parties'
      representatives on the regulatory  working  group  of  the CDRC, and such
      representatives  shall  discuss  in  good  faith,  and on a timely  basis
      determine, the most effective and expeditious means of responding to such
      FDA (or other Regulatory Authority) filing requirement.

            (iv)  In  connection with Articles 7.2(i), (ii)  and  (iii)  above,
      Organon shall provide  Pfizer  with  notice of all meetings, conferences,
      and  discussions  (including  without  limitation,   advisory   committee
      meetings  and  any  other  meeting  of  experts  convened by FDA or other
      Regulatory  Authorities  concerning any topic relevant  to  the  Product)
      scheduled with FDA or such  other  Regulatory  Authority  concerning  any
      pending  NDA,  Application  for  Regulatory Approval, or other regulatory
      matters  relating  to the Product within  two  (2)  Business  Days  after
      Organon receives notice of the scheduling of such meeting, conference, or
      discussion.  Pfizer  shall be entitled to have appropriate representation
      present at all such meetings  as  determined  by  the  CDRC.  Organon and
      Pfizer,  through  the CDRC, shall agree in advance on the  scheduling  of
      such meetings and on  the objectives to be accomplished at such meetings,
      conferences,  and  discussions  and  the  agenda  and  strategy  for  the
      meetings, conferences,  and  discussions  with  FDA  or  other Regulatory
      Authority.

      7.3.  Regulatory Matters in the Pfizer Exclusive Countries.  This Article
7.3 shall apply to clinical and regulatory matters relating to Product  in  the
Pfizer Exclusive Countries.

            (i)   After  the Effective Date, Pfizer will assume sole ownership,
      control of and responsibility  for  all  regulatory filings in the Pfizer
      Exclusive  Countries,  and  Organon  shall  cooperate   with   Pfizer  in
      connection  with  such  filings as reasonably requested by Pfizer and  at
      Pfizer's  sole  cost  and expense.   Organon  shall  be  responsible  for
      providing  Pfizer  with  Product  samples  for  use  in  connection  with
      regulatory filings relating  to Product in the Pfizer Exclusive Countries
      at Pfizer's sole cost and expense.

            (ii)  All Regulatory Approvals  in  the  Pfizer Exclusive Countries
      relating to the Product shall be deemed the property  of  Pfizer and held
      in Pfizer's or its Affiliate's name.  Upon termination of Pfizer's rights
      in any Pfizer Exclusive Country prior to the end of the applicable  Term,
      Pfizer  will promptly transfer to Organon or its designee, all Regulatory
      Approvals, Price Approvals and other approvals relating to the Product in
      the applicable  Country  as  may  be required by Organon or such party to
      market the Product in such Country.   The  transfer  fees  and  any  fees
      assessed  by any Governmental Authorities for such transfer will be borne
      by Organon.

            (iii) Pfizer   will   provide   Organon  with  (a)  notice  of  any
      revocations of Product Regulatory Approvals  and  any  Product recalls in
      the Pfizer Exclusive Countries; and


                                       41




      (b) responses to reasonable inquiries by Organon regarding the regulatory
      approval and  commercialization  processes  for the Product in the Pfizer
      Exclusive Countries.

      7.4.  Inquiries, Adverse Events, etc.

            (i)   Organon and Pfizer shall be responsible for the surveillance,
      receipt, evaluation, and reporting of Product complaints  and  reports of
      adverse  drug  experiences,  for  the Product in, as to Organon, the  Co-
      Promotion Countries and Organon Exclusive  Countries,  and, as to Pfizer,
      in the Pfizer Exclusive Countries, in accordance with Article  7.5 below.
      In  addition,  each  of  Organon and Pfizer will be responsible for  such
      matters with respect to any Regulatory Approvals that they own in any Co-
      Marketing Countries.

            (ii)  Organon  shall  be  responsible  for  promptly  investigating
      Product complaints and  reports  of  adverse  drug  experiences and other
      required  safety  information  (e.g.,  PSURs  and annual safety  reports)
      associated with the use of any Product in the Co-Promotion  Countries and
      Organon  Exclusive  Countries.  As to each Product, Organon shall  submit
      reports of all adverse  drug  experiences  associated with the use of the
      Product  and  other  required safety information  to  the  FDA  or  other
      Regulatory Authority and,  where  appropriate, clinical investigators, in
      accordance with applicable Law.  Organon shall submit a copy of each such
      report to Pfizer contemporaneously  with  its submission of the report to
      FDA  or  the  applicable Regulatory Authority,  or  in  advance  of  such
      submission if,  and  as,  reasonably necessary to permit Pfizer to comply
      with any Law applicable to it, if practicable.

            (iii) Pfizer  shall promptly  investigate  Product  complaints  and
      reports of adverse drug experiences and other required safety information
      (e.g., PSURs and annual  safety  reports)  associated with the use of any
      Product in the Pfizer Exclusive Countries.   As  to  the  Product, Pfizer
      shall submit reports of all adverse drug experiences associated  with the
      use  of  the  Product  and  other  required  safety  information  to  the
      applicable  Governmental  Authorities  and,  where  appropriate, clinical
      investigators  in  the  Pfizer  Exclusive  Countries  in accordance  with
      applicable  Law.   Pfizer  shall  submit  a copy of each such  report  to
      Organon for inclusion in the global database  contemporaneously  with its
      submission  of  the report to the applicable Regulatory Authority in  the
      Pfizer Exclusive  Countries, or in advance of such submission if, and as,
      reasonably necessary  to permit Organon to comply with any Law applicable
      to it, if practicable.

            (iv)  Organon shall  have  the sole responsibility for implementing
      decisions of the CDRC and revising  the  Product  labeling  for  the  Co-
      Promotion  Countries, the Organon Exclusive Countries, and for Regulatory
      Approvals owned  by  Organon  in  Co-Promotion Countries accordingly, and
      Pfizer shall have sole responsibility  for  revising the Product labeling
      for the Pfizer Exclusive Countries and for Regulatory  Approvals owned by
      Pfizer  in  Co-Marketing  Countries,  subject to review by the  CDRC,  as
      needed, to adequately warn of the potential  risks  identified by reports
      of adverse drug experiences associated with the use of  the  Product  and
      from Product complaints.

            (v)   Each  Party  shall  notify  the  other  Party  within two (2)
      Business Days after it receives information about the initiation  of  any
      investigation,  review  or inquiry by FDA or other Governmental Authority
      concerning the distribution,  promotion  or  sale  of  the  Product,  not
      otherwise described above.

      7.5.  Product   Surveillance.    The   Parties   will  cooperate  in  the
collection, review, assessment, tracking and filing of information  related  to
adverse  events  associated  with the Product in accordance with 21 CFR 312.32,
314.80,  or  comparable  Laws  in  other  Countries.   As  soon  as  reasonably
practicable after the Effective Date, and subject to the oversight of the CDRC,
the pharmacovigilance departments  of both Parties shall meet and determine the
approach  to  be taken for the collection,  review,  assessment,  tracking  and
filing of information  related  to  adverse events associated with the Product,
which shall be documented in a separate  drug safety exchange agreement between
the Parties.  In the event of any


                                       42




conflict  between the terms of Articles 7.4 and 7.5 of this  Agreement  and the
terms of such separate  drug safety  agreement as those terms relate to adverse
events  relating  to the  Product,  the  terms  of such  separate  drug  safety
agreement  shall control.  Until such time as the Parties have agreed upon such
adverse event exchange  procedures,  without  limiting the terms of Article 7.4
above, each Party will notify the other Party of fatal/life-threatening serious
clinical trial adverse event  involving the Product  within 96 hours  following
receipt by the Party.  All other serious  clinical  trial adverse event reports
involving  the Product will be exchanged  within  fifteen (15) calendar days of
receipt by the Party.  Organon shall be  responsible  for  maintaining a global
safety  database  for  the  Product  consistent  with  pharmaceutical  industry
practice and all applicable Laws.

      7.6.  Data Sharing.  Each Party shall provide  to  the  other Party, on a
timely  basis  copies of all pre-clinical and clinical data and all  regulatory
filings,  applications  and  registrations  in  the  Territory  concerning  the
Product.  Such  data, filings and other information received from a Party shall
be treated by the  other  Party  as  Confidential Information of the disclosing
Party.  Each Party agrees to identify non-material, routine, regulatory filings
which such Party will not have to provide, pursuant to this Article 7.6.

      7.7.  Product Recalls. Any decision to initiate a recall or withdrawal of
Product in the Co-Promotion Countries  shall be made by the Steering Committee.
Before the Steering Committee initiates  a  recall  or withdrawal, and upon the
request for a recall or withdrawal by either Party, the  Parties shall promptly
and in good faith discuss the reasons therefor.  Under no  circumstances  shall
either  Party  unreasonably  object  to a recall or withdrawal requested by the
other Party, and neither Party shall have  any  right  to object to a recall or
withdrawal requested by the other Party for failure of a  Product  to  meet the
Specifications, for material safety concerns or for noncompliance with the Act,
and such recall shall be initiated by the Party that requested the recall  (the
"Requesting  Party").  In the event of any recall or withdrawal, the Requesting
Party shall implement  any  necessary  action,  with  assistance from the other
Party as reasonably requested.  In addition, and except as set forth in Article
12, the Parties shall bear equally all costs and expenses of any such recall or
withdrawal, including, without limitation, documented and  direct Out-of-Pocket
Costs incurred in relation thereto, expenses and other costs  or obligations to
Third Parties, the cost and expense of notifying customers and  the  costs  and
expenses  associated  with  shipment  of  the recalled Product and the cost and
expense of destroying the Product removed from the market, if necessary.

such costs and expenses if the number of Details  determined by the independent
accountant  is at least ten  percent  (10%)  lower  than the  number of Details
reported by the Detail  Reporting  Party under Article 8A.6 for such Year. Such
independent  accountant shall not reveal to the Party seeking  verification the
details  of its  review,  except  for such  information  as is  required  to be
disclosed under this Agreement or to determine  compliance with this Agreement.
Such  independent  accountant  must  agree  to be  subject  to  confidentiality
obligations  consistent  with the  provisions  of Article  14. The  independent
accountant  shall  deliver its report to each Party within  thirty (30) days of
receipt of all relevant  materials from the Detail  Reporting Party. The report
of the independent  accountant shall be final and binding. If upon verification
by the  independent  accountant,  it is determined at the end of the applicable
Year that the Detail  Reporting  Party is a Shortfall  Party then within thirty
(30) days of receipt of such  audit  report,  the  Shortfall  Party  shall make
payment to the other Party of all amounts due under Article 6.9.

      Net  Sales  in  any  foreign currency shall be computed by (a) converting
      such amount for the relevant  Pfizer  Quarter  or  Calendar  Quarter,  as
      applicable,  into Euros or US Dollars, as applicable, at the spot rate of

      product of 1) the average of the spot U.S. dollar exchange rates for such
      Country's  local currency in effect each day of such  calendar  month  as

      amount of any Co-Promotion payment due  from Organon to Pfizer that is to
      be paid, by mutual agreement of the Parties,  in some currency other than
      the local currency of the applicable Co-Promotion  Country, the amount of
      the  Co-Promotion  Payment due shall first be computed  in  the  relevant
      local currency and shall  then  be converted into the currency of payment
      at the spot rate of exchange for  purchasing  such  payment currency with
      such local currency as published in the Financial Times five (5) Business

to the respective account designated  in writing by each Party at least two (2)
Business  Days  before  the  payment is due.   Pfizer  shall  notify  Organon's

representative  as Pfizer's Treasurer shall designate in writing, by  facsimile
transmission as to  the  date and amount of any payment that Organon shall make

Agreement shall bear interest  from  the date due until paid at a rate equal to
the prime rate of the Bank of America as announced on the date such payment was
due plus three percent (3%).  In addition,  the  Party  liable for late payment
shall  reimburse  the  other  Party  for  all  reasonable costs  and  expenses,
including without limitation reasonable attorneys'  fees  and  legal  expenses,
incurred in the collection of late payments.

      9.6 Records.   Each  of Pfizer and Organon (the "Payor") shall, and  shall
cause its Affiliates and sublicensees  to,  keep  full  and  accurate books and
records setting forth Development Costs, Cost of Goods, Marketing  Costs, gross
sales,  Net  Sales,  and  any amounts payable to the other Party (the "Payee").
The  Payor  shall  permit the  Payee,  at  the  Payee's  sole  expense,  by  an
internationally recognized  independent accountant selected by the Payee (as to
which the Payor has no reasonable objection), to examine such books and records
upon at least thirty (30) days'  advance  written notice during normal business
hours  and  in a manner that does not materially  interfere  with  the  Payor's
business, but  not  later  than  three (3) years following the rendering of any
such reports, accountings and payments.   The  foregoing right of review may be
exercised  only  once with respect to each such periodic  report  and  payment.
Such independent accountant  may  be  required  by  the  Payor  to enter into a
reasonably  acceptable  confidentiality agreement, and in no event  shall  such
independent accountant reveal  to  the  Payee  the details of its review except
insofar as is necessary to verify the accuracy of  reports and payments made or
due hereunder.  The results of any such audit shall  be delivered in writing to
each Party.  Any underpayment determined by such audit  shall  promptly be paid
or  refunded by the Payor.  If the Payor has underpaid amounts due  under  this
Agreement  by  more than five percent (5%) over any reporting period, the Payor
shall also reimburse the Payee for the cost of such audit (with the cost of the
audit to be paid  by  the  Payee  in  all  other  cases),  plus interest at the
interest rate set forth in Article 9.5, from the date of any such underpayment.

      9.7 Withholding Tax.

            (i)   Any taxes required to be paid or withheld  by either Party or
      its  Affiliates  for  the  account of the other Party on amounts  payable
      under this Agreement shall be  deducted  from  the amounts payable at the
      rates specified by applicable Law.  In addition,  the  paying Party shall
      provide  promptly  to  the  other  Party receipts from the government  or
      taxing authority-evidencing payment of such taxes.

            (ii)  Each Party shall be indemnified  against and held harmless by
      the  other  Party  (or its assignee) from any incremental  tax  liability
      (including but not limited  to  VAT or withholding taxes) imposed on such
      Party as the result of an assignment  by the other Party of its rights or
      obligations under this Agreement pursuant  to Article 16.5.  In the event
      of any such assignment, (a) the assignee shall  gross  up any payments it
      makes  to  the extent necessary so that the net payment received  by  the
      non-assigning  Party  after any such incremental tax liability equals the
      amount the non-assigning  Party would have received if no assignments had
      made by the other Party or  its  Affiliates  under  this  Agreement;  and
      (b) for  the  avoidance  of  doubt,  the non-assigning Party shall not be
      required to pay any gross up or other  amounts  to the assigning Party on
      account  of any taxes (including but not limited to  VAT  or  withholding
      taxes) that  would  not  have  been  imposed but for such assignment. The
      Parties further agree that if the non-assigning  Party


                                       51




      uses a tax  credit to reduce  its  taxes  within  five (5) years and as a
      result of any  incremental  tax liability  related to such assignment and
      paid by the  assigning  party  pursuant to the  preceding  sentence,  the
      non-assigning  Party shall  reimburse the  assigning  Party the amount of
      such realized tax credit.

            (iii) For the avoidance of doubt,  the Initial Fee, Event Milestone
      Payments and Performance Milestones Payments  made  by  Pfizer to Organon
      under this Agreement shall be exclusive of VAT.  The Parties  agree  that
      at  the date of this Agreement all payments due hereunder are outside the
      scope  of VAT.  Organon agrees to inform Pfizer if Organon concludes that
      there is  a change in VAT law or practice that requires it to account for
      VAT on any  payments due pursuant to this Agreement at any time after the
      execution date.   In the event of any such change in VAT law or practice,
      Organon shall pay VAT  on behalf of Pfizer and Pfizer shall prior thereto
      assign to Organon Pfizer's  refund  claim  in respect thereof, and Pfizer
      shall co-operate with Organon in securing a refund to Organon of the full
      amount of such VAT payment.

      9.8 Third Party License Fees. Organon shall  be responsible for all Third
Party  License  Fees  relating  to  (i)  the  Current  Product   and  (ii)  the
manufacturing process identified in Schedule 9.8, provided however  that  Third
Party  License  Fees  payable to [CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND

change to the manufacturing process identified in Schedule 9.8. With respect to
Pfizer's  responsibility  for  [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED  AND

Quarterly invoice that shall be based on Organon's Calendar Quarterly report of
Net  Sales  pursuant  to  Article  8A.4  and shall reflect the amounts due from
Pfizer under this Article 9.8.  Pfizer shall,  within  fifteen  (15) days after
its  receipt  of  such  invoice,  make payment under such invoice by electronic
transfer in immediately available funds to the account designated in writing by
Organon, which designation shall take  place  at  least  two  (2) Business Days
before the payment is due.

      9.9 Adjustment of Commercial Terms. It is agreed by the Parties  that the
Parties'  Co-Promotion  of  a  Combination  Product may require a change to the
applicable financial terms of this Agreement with respect to the sharing of Net
Sales  of such Combination Product Accordingly,  upon  the  request  of  either
Party, the Parties shall undertake good faith negotiations to reasonably adjust
the same in accordance with the principles set forth in this Agreement.

      the issue to the Steering Committee for resolution.

      10.8 Steering Committee. The Steering Committee shall consist of four (4)
executives,  two (2) from  each of  Organon  and  Pfizer,  each of which  shall
confirm to the other its designees. In addition, the co-chairpersons of the JOC

                                  ARTICLE 11


                             INTELLECTUAL PROPERTY

      11.1  Ownership  of  Collaboration  Inventions.  As between  Organon  and
Pfizer,  (i) Organon  shall solely own all  Collaboration  Inventions  invented
solely by  Organon's  employees  and agents,  (ii) Pfizer  shall solely own all
Collaboration  Inventions invented solely by Pfizer's employees and agents, and
(iii) the Parties shall jointly own all  Collaboration  Inventions  invented by
employees and agents of both Parties. The Parties agree that inventorship shall
be determined in accordance with United States patent law,  provided,  however,
that,  without  limiting the foregoing,  in preparing  patent  applications for
Collaboration  Inventions,  each Party shall  follow the Laws of the Country in
which such application is being filed. Each Party shall have the first right to
prosecute and maintain Patent Rights included in the  Collaboration  Inventions
solely  owned by such  Party.  Neither  Party shall  abandon any Patent  Rights
included in the Collaboration Inventions that such Party has the first right to
prosecute and maintain  without at least 90 days' prior written  notice of such
abandonment  to the other Party.  If a Party decides to abandon any such Patent
Rights,  the other Party shall have the option to continue the  prosecution and
maintenance of such Patent Rights in the name(s) of the Party or Parties owning
such Patent Rights and at such other Party's expense.  The costs of prosecuting
and maintaining Patent Rights included in the Collaboration Inventions shall be
shared  equally by the Parties in each Co- Promotion  Country and  Co-Marketing
Country,  Pfizer  will bear all such costs in the Pfizer  Exclusive  Countries,
Organon  will  bear all such  costs in the  Organon  Exclusive  Countries,  and
provided  that either Party may elect not to pay such costs with respect to any
given Patent Rights included in the  Collaboration  Inventions being prosecuted
and/or  maintained by the other Party incurred from and after such time as such
Party  notifies the other Party of such  election,  and thereafter any licenses
granted in this  Agreement by the other Party to the Party making such election
shall exclude such Patent  Rights.  Such costs of prosecuting  and  maintaining
Patent Rights  included in the  Collaboration  Inventions  in the  Co-Promotion
Countries  shall be shared  equally by the Parties and included in the Parties'
Quarterly  Marketing Cost Reports  pursuant to Article 8A.1 of this  Agreement.
Pfizer  shall  reimburse   Organon  for  all  such  costs  of  prosecuting  and
maintaining


                                       60




Patent Rights included in the Collaboration  Inventions in the Pfizer Exclusive
Countries  incurred  by Organon  within  thirty (30) days after  receiving  any
invoice from Organon for such costs.

      11.2  Jointly  Owned  Collaboration  Inventions.   With  respect  to  any
Collaboration  Inventions  that are jointly  owned by the Parties,  the Parties
shall consult with each other regarding the filing, prosecution and maintenance
of any such Patent Rights,  and responsibility for such activities shall belong
to Organon. Organon shall undertake such filings,  prosecutions and maintenance
in the names of both Parties as  co-owners.  Organon  shall have the  following
obligations  with respect to the filing,  prosecution and maintenance of Patent
Rights in jointly  owned  Collaboration  Inventions:  (i) Organon  shall permit
Pfizer to review and  comment at least two (2) weeks prior to the filing of any
priority patent application by Organon; (ii) Organon shall notify Pfizer within
thirty (30) days after the filing of a patent  application  by  Organon;  (iii)
Organon  shall  notify  Pfizer  within  six (6)  months  from the filing of the
priority patent  application  whether and in which Countries it intends to file
convention patent applications; (iv) Organon shall provide Pfizer promptly with
copies of all  communications  received  from or filed in patent  offices  with
respect to such filings;  and (v) Organon shall  provide  Pfizer,  a reasonable
time prior to taking or failing to take action  that would  affect the scope or
validity of rights under any patent  applications or Patents (including but not
limited to substantially narrowing or canceling any claim without reserving the
right to file a continuing or divisional  patent  application,  abandoning  any
Patent or not filing or perfecting the filing of any patent  application in any
country),  with notice of such proposed action or inaction so that Pfizer has a
reasonable  opportunity to review and make  comments,  and take such actions as
may be appropriate in the  circumstances.  In the event that Organon materially
breaches the foregoing  obligations  and such breach is not cured within thirty
(30) days of a written notice from Pfizer to Organon describing such breach, or
in the event that Organon fails to undertake the filing of a patent application
within  ninety  (90) days of a written  request by Pfizer to do so,  Pfizer may
assume Organon's responsibility for filing,  prosecution and maintenance of any
such jointly owned Patent Right in the manner described in Article 11.6.

      11.3 Collaboration  Intellectual Property. All Collaboration Intellectual
Property  shall be jointly owned by the Parties,  and each Party shall have the
right freely to use all  Collaboration  Intellectual  Property for all purposes
and uses.

      11.4  Cooperation.  Each Party  agrees to  cooperate  with the other with
respect to the preparation,  filing, prosecution and maintenance of patents and
patent applications pursuant to this Article 11 including,  without limitation,
the execution of all such documents and instruments and the performance of such
acts (and  causing  its  relevant  employees  to  execute  such  documents  and
instruments  and to perform such acts) as may be reasonably  necessary in order
to permit the other Party to continue any preparation,  filing,  prosecution or
maintenance  of any Patent  Rights that such Party has elected not to pursue as
provided for in Article 11.2.  Organon shall  recommend to the JOC which of the
Organon  Patent  Rights for which to seek an extension of term in  Co-Promotion
Countries in which any such extension is available.  Upon  confirmation  of the
recommendation  of Organon  with  respect to patent term  extension by the JOC,
Organon will file for said patent term  extension,  and the Parties  shall bear
equally the costs thereof.

      11.5 Notification.  If either Party during the Term makes a Collaboration
Invention,  such Party promptly shall make or cause  disclosure to the other of
such Collaboration Invention.

      11.6 Maintenance of Patent Rights other than Jointly Owned Patent Rights.

            (i)   Organon  will  maintain  in full force and effect all Organon
      Patent Rights.  Organon shall cooperate  with  Pfizer  in  the  continued
      prosecution and maintenance by Organon or the licensor or sublicensor, as
      applicable,  of  the  Organon  Patent  Rights.  After the Effective Date,
      Organon shall not, without Pfizer's consent, enter  into  any Third Party
      license  agreement  relating  to  Patent Rights that Organon proposes  to
      license from a Third Party and that  Organon  reasonably  foresees would,
      upon the execution of such Third Party license agreement, result  in


                                       61




      the creation of any Pfizer obligation pursuant to this Agreement to share
      in or pay any portion of the  royalties or other  amounts  payable  under
      such Third Party license agreement.

            (ii)  Organon shall  not  abandon  any  Organon  Patent Rights with
      respect  to  which Organon or any of its Affiliates controls  prosecution
      and maintenance  activities,  either  directly  or through step-in rights
      granted to Organon in any Third Party license agreement, without at least
      90 days' prior notice of such abandonment to Pfizer.   If Organon decides
      to  abandon  any  such  Patent  Rights, Pfizer shall have the  option  to
      continue  the  prosecution  and maintenance  of  such  Patent  Rights  in
      Organon's name at Pfizer's expense,  subject to any limitations set forth
      in Organon's agreements with Organon's  licensors  and  sublicensors.  If
      Pfizer  desires  that  Organon  file  any application for a patent  in  a
      specific  Country  or  Countries,  or file  any  patent  applications  on
      improvements  and variations upon inventions  disclosed  in  the  Organon
      Patent Rights set  forth  on  Schedule  1.94 or otherwise relating to the
      Compound or the Product, Pfizer shall advise  Organon  of such Country or
      Countries or improvements, variations or inventions, as  the case may be.
      Organon  shall  consider  Pfizer's  request in good faith and  shall  not
      unreasonably decline to file the requested  patent  application  and,  if
      Organon  files  the  patent  applications  as requested, Pfizer shall pay
      fifty percent (50%) of all reasonable expenses, including reasonable fees
      for patent counsel, for filing and for prosecuting  such requested patent
      applications.   If  Organon declines to file the patent  applications  as
      requested, Pfizer may,  at  its  sole  expense,  file  and prosecute such
      applications.  Pfizer shall have reasonable access to all  documentation,
      filings and communications  to  or from the respective patent offices and
      shall be kept advised as to the status of all pending applications to the
      extent  pertaining to the Compound  or  the  Product.   Unless  otherwise
      explicitly  set  forth above in this Article 11.6, the Parties shall each
      be responsible for 50% of the Parties' patent prosecution and maintenance
      costs relating to  the  Organon Patent Rights.  Organon shall include all
      such costs in Organon's Quarterly  Marketing  Cost  Reports  pursuant  to
      Article 8A.1 of this Agreement.

      11.7 Trademarks and Corporate Logos.

            (i)   Subject  to  the  provisions of this Article 11.7, each Party
      shall retain all right, title and  interest  in  and  to  its  respective
      corporate name and logo.

            (ii)  In the Co-Promotion Countries, the Product shall be  promoted
      and  sold  solely  under  the  Trademark(s)  and  shall use a trade dress
      mutually  agreed  by  the  Parties that includes Pfizer's  and  Organon's
      logos.  In the Co-Promotion  Countries,  subject  to  the requirements of
      Law, Organon and Pfizer shall be identified and given equal  exposure and
      prominence  on  all  Product  package inserts, trade packages, packaging,
      samples, and Promotional Materials; provided, however, that if Organon or
      Pfizer  cannot be given equal exposure  and  prominence  on  all  Product
      package inserts,  trade  packages,  packaging,  samples,  and promotional
      materials  in  one  or  more  Co-Promotion Countries as a result  of  the
      requirements of applicable Law,  then  Organon or Pfizer, as the case may
      be, shall be given as close to equal exposure and prominence as possible,
      consistent  with  applicable  Law.  In the  Pfizer  Exclusive  Countries,
      Pfizer will promote and sell the  Product  under  a  Trademark, but shall
      have  the  sole  right  and obligation to determine the trade  dress  and
      packaging for the Product,  provided that it makes such determinations in
      a  manner consistent with the  Global  Marketing  Plan.  In  the  Organon
      Exclusive  Countries,  Organon  will promote and sell the Product under a
      Trademark, but shall have the sole  right and obligation to determine the
      trade dress and packaging for the Product,  provided  that  it makes such
      determinations in a manner consistent with the Global Marketing Plan.

            (iii) It  is  the Parties' intention to utilize a single  trademark
      for the Product throughout  the  Territory other than in the Co-Marketing
      Countries where the Product must be  marketed  and  sold  by  the Parties
      under different Trademarks by operation of local Law; provided,  however,
      if  any  Governmental  Authority  in  the  Territory fails to approve the
      Trademark as an acceptable trademark for the  Product, or if either Party
      reasonably determines that use of the Trademark  in  a particular Country
      may  violate  the  rights  of any Third Party in such Country,  then  the
      Parties shall select an alternative  Trademark  for  the  Product in such
      Country   or  Countries.   In  either  event,


                                       62




      Organon shall be solely  responsible for registering and maintaining such
      alternative  Trademark in the Pfizer Exclusive Countries and shall be the
      owner  thereof.  Pfizer  shall  not  register  or  seek to  register  the
      Trademark  or any  alternative  Trademark  selected by the Parties in any
      Country of the Territory.

            (iv)  During the Term, Pfizer grants to  Organon  the non-exclusive

      purpose of Co-Promotion  of  the Products in accordance with the terms of
      this Agreement; provided that  such  rights  shall  be exercised, and all
      Products  bearing  such  names  and/or  logos  shall be manufactured,  in
      accordance with the quality standards established by the GCC.

            (v)   During the Term, and thereafter as provided  in Article 13.8,
      Organon grants to Pfizer the non-exclusive right to use the Trademarks in
      connection with the marketing, promotion and sale of the Product  in  (a)
      the  Pfizer  Exclusive  Countries and, (b) other than the Trademark being
      used  by  Organon in each such  Co-Marketing  Country,  the  Co-Marketing
      Countries.

            (vi)  Organon  shall  remain the owner of the Organon name and logo
      and the Trademark(s) and the  goodwill pertaining thereto.  Organon shall
      be solely responsible for registering and maintaining the Trademark(s) in

      herein, Organon shall have no rights  in or to the Pfizer name or logo or
      the goodwill pertaining thereto.  Except  as  contemplated herein, Pfizer
      shall  have  no rights in the Trademark(s) in the  Territory  or  to  the
      Organon name or logo, or the goodwill pertaining thereto.

            (vii) Organon  and  Pfizer  shall  each  be  responsible  for fifty
      percent (50%) of the cost of registering and maintaining the Trademark(s)
      in  the  Territory.   Organon  shall include all such Territory costs  in
      Organon's Quarterly Marketing Cost Reports pursuant to Article  8A.1.

            (viii) Copyrights  and  Proprietary  Programs.  The  Parties  shall
      jointly own all copyrights relating  to  Promotional  Materials developed
      for  use  in  the  Co-Promotion  Territory for the Product.   Pfizer  and
      Organon  shall  each  retain all rights  including,  without  limitation,
      copyrights and trademarks,  to  all of their respective existing programs
      and materials in all formats (print,  video,  audio,  digital,  computer,
      etc.)  regarding sales training, patient education and disease management
      programs  owned  by each of them as of the Effective Date, as well as any
      modifications each  may  develop  in the future which are not specific to
      the Product.  Organon and Pfizer shall,  from  time  to time, endeavor to
      each  notify the other as to the identity of such existing  programs  and
      materials.   In  addition,  all  new  programs  regarding sales training,
      patient education and disease management jointly developed by Organon and
      Pfizer for the Products pursuant to this Agreement shall be jointly owned
      by Organon and Pfizer, and each Party shall have  the  right  to  use and
      exploit  such  developed  programs  freely without any need to obtain the
      consent of the other Party and without  any  duty to account to the other
      Party for such use or exploitation.  Each Party  hereby  assigns  to  the
      other  Party  all rights, title and interests, including all intellectual
      property rights,  in  and  to  such Promotional Materials and programs as
      necessary to give effect to the provisions of this Article 11.7.

            (ix)  Domain  Names.   Organon  shall  be  solely  responsible  for

      and  maintaining  the domain names comprising the Trademark(s).   Organon
      shall  include all such  costs  in  Organon's  Quarterly  Marketing  Cost
      Reports pursuant to Article 8A.1.

      Agreement. Organon and Pfizer shall each be responsible for fifty percent
      (50%) of the costs of registering  and  maintaining  such  copyrights and
      internet sites.

      11.8  Disclosure.  Organon shall disclose to Pfizer the complete texts of
all patent  applications  within the Organon Patent Rights filed by Organon, or
by Organon's licensors to the extent Organon is permitted to provide such texts
to Pfizer under the terms of Organon's agreements with such licensors,  as well
as information  received concerning the institution or possible  institution of
any  interference,  opposition,  re-examination,  reissue,  revocation  or  any
official  proceeding  involving  patents  and  patent  applications  within the
Organon Patent Rights prosecuted and/or maintained by Organon,  or by Organon's
licensors to the extent  Organon  receives  such  information,  anywhere in the
Territory.  Pfizer shall have the right to review all such pending applications
and other  proceedings and make  recommendations  to Organon,  and to Organon's
licensors  if  permitted  under the  terms of  Organon's  agreements  with such
licensors,  concerning  such  applications  and  proceedings and their conduct.
Organon agrees,  subject to any  limitations set forth in Organon's  agreements
with  Organon's  licensors,  to keep Pfizer  promptly and fully informed of the
course of such patent  prosecution  and other  proceedings  including,  without
limitation,  by providing Pfizer with copies of all substantive  communications
submitted to or received from patent  offices  throughout  the  Territory.  The
provisions  of this  Article 11.8 also shall be deemed to apply in all respects
to Pfizer as it relates to Pfizer Patent Rights in Collaboration Inventions.

      11.9 Patent Term Extensions.  The Parties shall  cooperate,  if necessary
and  appropriate,  with each other in gaining patent term  extensions  wherever
applicable  to Organon  Patent  Rights.  The Parties  shall,  if necessary  and
appropriate,  use reasonable efforts to agree upon a joint strategy relating to
patent term extensions, but, in the absence of mutual agreement with respect to
any  extension  such,  and subject to Law, a patent shall be extended if either
Party elects to extend such patent.  The Parties shall each be responsible  for
fifty  percent  (50%) of the costs of  seeking  and/or  obtaining  patent  term
extensions  relating to the Organon  Patent  Rights in the  Territory.  Organon
shall include all such costs in Organon's  Marketing  Cost Reports  pursuant to
Article 8A.1 of this Agreement.

      11.10  Infringement,  Unauthorized  Use and  Challenge.  If either  Party
becomes aware that a Third Party is or may be  infringing  or otherwise  making
unauthorized use of, or challenge to, any Organon Patent Rights,  Patent Rights
in jointly owned  Collaboration  Inventions,  Trademarks  or Organon  Technical
Information,  the Party learning of such  infringement or  unauthorized  use or
challenge  shall  promptly  notify  the  other  Party and  provide  it with any
available  evidence  of  such  possible  infringement  or  unauthorized  use or
challenge. In the Pfizer Exclusive Countries, Pfizer shall have the first right
to bring suit and to take action against such infringer or unauthorized user or
challenger in its own name, or in the name of Organon where necessary, in which
case Pfizer shall control the prosecution of any such suit or claim,  including
without limitation the choice of counsel, and shall have the exclusive right to
settle or dispose of any such suit or claim. In the Organon Exclusive Countries
and the  Co-Marketing  Countries,  Organon  shall have the first right to bring
suit  and to  take  action  against  such  infringer  or  unauthorized  user or
challenger in its own name, in which case Organon shall control the prosecution
of any such suit or claim,  including without limitation the choice of counsel,
and shall  have the  exclusive  right to settle or  dispose of any such suit or
claim.  In the  Co-Promotion  Countries,  as between  Pfizer and  Organon,  and
subject to any rights retained by Organon's  licensors,  Organon shall have the
first  right to  bring  suit  and to take  action  against  such  infringer  or
unauthorized  user or  challenger  in its own name, in which case Organon shall
control the prosecution of any such suit or claim, including without limitation
the choice of counsel,  and shall have the exclusive right to settle or dispose
of any such suit or claim.  Notwithstanding  anything  to the  contrary in this
Article  11.10,  if a Party fails to initiate a suit or take other  appropriate
action  that it has the  initial  right to  initiate  or take  pursuant to this
Article 11.10 or the Parties fail to agree on the  initiation or taking thereof
within  ninety  (90) days  after  becoming  aware of the basis for such suit or
action,  then the other  Party  shall have the  right,  in its  discretion,  to
initiate a suit or take other appropriate action that it believes is reasonably
required to protect the intellectual property rights at issue.  Notwithstanding
the foregoing  provisions of this Article 11.10, in the case of an infringement
action pursuant to Section 505(b) of the Act, subject to any legal  obligations
of Organon to its licensors with respect to Organon Patent Rights, if the Party
that has the initial  right to initiate  such action  fails to notify the other
Party, at least fifteen (15) days prior to such Party's  deadline under the Act
for  bringing  such action,  that such Party will bring such  action,  then the
other Party may, in its  discretion,  initiate such action after giving


                                       64




written notice of such election to the Party with the initial right to initiate
such action.  The proceeds of any  recovery,  court award or settlement of such
action  shall,  after any required  payments to Organon's  licensors,  first be
applied to reimburse the Parties for the costs and expenses of such prosecution
and the  balance  shall be paid 50% to Pfizer and 50% to  Organon.  The Parties
shall cooperate and take action to assist the other as is reasonably  necessary
in relation to all suits or claims brought under this Article 11.10.

      11.11 [CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
TO THE SECURITIES AND EXCHANGE  COMMISSION]  Agreement.  Organon  covenants and
agrees  with  Pfizer  that  Organon:  (a)  shall  not  execute  any  amendment,
modification  or  waiver  of the  license(s)  contained  in  the  [CONFIDENTIAL
INFORMATION  HAS BEEN OMITTED AND FURNISHED  SEPARATELY TO THE  SECURITIES  AND
EXCHANGE COMMISSION] Agreement without the prior written consent of Pfizer, (b)
shall not make any  election or  exercise  any right or option (or omit to take
any  action)  that  would  terminate  or  relinquish  in  whole  or in part the
[CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND  FURNISHED  SEPARATELY  TO THE
SECURITIES AND EXCHANGE COMMISSION] Agreement, (c) shall comply with all of its
obligations under the [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED
SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION] Agreement in all material
respects,  (d) shall take such reasonable actions as shall be necessary to keep
in full force and effect the  [CONFIDENTIAL  INFORMATION  HAS BEEN  OMITTED AND
FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION] Agreement,  and
(e) shall give prompt notice to Pfizer,  together with a summary of outstanding
issues if Pfizer so requests and of any actual or alleged  defaults,  breaches,
violations,  proposed amendments or proposed  modifications of, or any proposed
waivers under,  the  [CONFIDENTIAL  INFORMATION  HAS BEEN OMITTED AND FURNISHED
SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION] Agreement by any party to
the [CONFIDENTIAL  INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY TO THE
SECURITIES AND EXCHANGE COMMISSION] Agreement.

      violation of a Third Party's intellectual property rights  arising out of
      or   related   to  the  Organon  Patent  Rights,  the  Organon  Technical
      Information and/or  the manufacture (by the process described on Schedule
      9.8), use, sale, offer for sale, or importation of the Current Product or
      any Organon-Only Product;

            (iv)  Organon's  or  any  of its Affiliates' failure to manufacture
      and package in accordance with the  Production  Agreements,  or  to cause
      Third  Parties  to  manufacture,  the  Product in accordance with (A) the
      then-existing Product Specifications as determined in accordance with the
      terms of this Agreement, or (B) cGMP;


                                       65




            (v)   Organon's use, sale, offer for  sale,  or  importation of any
      Organon-Only Product; or

            (vi)  any  breach  by  Organon  or  any  of its Affiliates  of  any
      representation,  warranty  or  covenant  given  in any  of  the  Alliance
      Agreements.

      Notwithstanding anything to the contrary contained  herein,  none  of the
      indemnities in this Article 12.2 shall apply to the extent that any  Loss
      is the result of any breach of this Agreement by Pfizer or of any willful
      misconduct of Pfizer Parties.

      12.3 Indemnification by Pfizer.  Pfizer shall indemnify and hold harmless
Organon  and its  Affiliates  and  their  respective  directors,  officers  and

            (i)   any violation of Law by Pfizer or its Affiliates; or

            (iv)  Pfizer's or any of its Affiliates' failure  to manufacture in
      accordance with the Production Agreements, or to cause Third  Parties  to

      Notwithstanding anything  to  the  contrary contained herein, none of the

      is  the result of any breach of this Agreement   by  Organon  or  of  any
      willful  misconduct of Organon Parties or is the subject of the indemnity
      contained in Article 12.2 (including without limitation Article 12.2(v)).

            (i)   Product  Liability.  Organon shall indemnify, defend and hold

      of the amount of any and all Losses  arising out of or resulting from any
      Third  Party  Claim involving death, bodily  injury  or  property  damage
      actually or allegedly  arising  out of or resulting from the manufacture,
      packaging, distribution, marketing, use and/or sale of the Product (other
      than with respect to the matters  for  which  one  Party  is obligated to
      indemnify  the other Party pursuant to Article 12.2 or 12.3  above)  (any
      and all such  Losses,  "Product  Liability") up to, in the aggregate, the
      Threshold Amount with respect to all  Product Liability Occurences in the
      Territory after the date hereof and prior  to  the  initial Launch of the
      Product on a Country-by-Country basis.  Organon shall  indemnify,  defend
      and hold the Pfizer Parties harmless from and against fifty percent (50%)
      of  the  amount of any and all Product Liability (a) prior to the initial
      Launch of  the Product in each Country, in excess of the Threshold Amount
      or (b) with  respect  to  any  Product  Liability  Occurrences  after the
      initial  Launch  of the Product in a Country, and Pfizer shall indemnify,

      [CONFIDENTIAL INFORMATION HAS BEEN  OMITTED  AND  FURNISHED SEPARATELY TO
      THE  SECURITIES  AND  EXCHANGE  COMMISSION] U.S. Dollars  ($[CONFIDENTIAL
      INFORMATION HAS BEEN OMITTED AND  FURNISHED  SEPARATELY TO


                                       66




      THE SECURITIES AND EXCHANGE  COMMISSION]) of Product Liability determined
      on a first-to- be incurred or  discovered  basis  (whichever is earlier),
      and (B) "Product Liability Occurences" means, with respect to all Product
      Liability,  the initial time of sale or other  provision to the plaintiff
      of the relevant  Product for which any Product  Liability  relates  based

            (ii)  Organon shall indemnify, defend and hold the  Pfizer  Parties
      harmless  from  and against fifty percent (50%) of the amount of any  and
      all Losses arising  out  of  or  resulting  from  any  Third  Party Claim
      involving any actual or alleged infringement, misappropriation  or  other
      violation of a Third Party's intellectual property rights arising out  of
      or   related   to  the  Organon  Patent  Rights,  the  Organon  Technical
      Information  and/or   use,   promotion,  manufacture,  commercialization,
      distribution, offering for sale,  sale or importation of the Product (but
      in  all  cases  excluding Losses for which  one  Party  is  obligated  to
      indemnify the other  Party pursuant to this Article 12, including without
      limitation, Article 12.2(iii)  above)  (any  and all such Losses, the "IP
      Liability"), and Pfizer shall indemnify, defend  and hold Organon Parties
      harmless from and against fifty percent (50%) of the  amount  of  any and
      all of such IP Liability; it being understood and agreed that the purpose
      of  the provisions of this sentence is that Pfizer and Organon shall  pay
      for and otherwise share the cost of the IP Liability equally.

            (iii) For  the  avoidance  of  doubt, the reference to "Product" in
      this Article 12.4 excludes Organon-Only Product.


      12.5 Procedures for Third Party Claims.

            (i)   In  the  event that any Third  Party  asserts  a  Claim  with
      respect to any matter  for  which  a  Party  (the "Indemnified Party") is
      entitled to indemnification hereunder (a "Third  Party  Claim"), then the
      Indemnified Party shall promptly notify the Party obligated  to indemnify
      the  Indemnified  Party  (the  "Indemnifying  Party") thereof in writing;
      provided, however, that no delay on the part of  the Indemnified Party in
      notifying  the  Indemnifying Party shall relieve the  Indemnifying  Party
      from any obligation  hereunder  unless (and then only to the extent that)
      the Indemnifying Party is prejudiced thereby.

            (ii)  The Indemnifying Party  shall  have the right, exercisable by
      written notice to the Indemnified Party within  ten  (10) days of receipt
      of notice from the Indemnified Party of the commencement  of or assertion
      of  any  Third  Party  Claim,  to assume the defense of such Third  Party
      Claim; provided, however, that (A)  the  Third  Party  Claim  seeks  (and
      continues  to  seek)  solely  monetary damages and the Indemnifying Party
      expressly agrees in such notice  that,  as between the Indemnifying Party
      and  the  Indemnified  Party,  the Indemnifying  Party  shall  be  solely
      obligated to satisfy and discharge the Third Party Claim (or, in the case
      of  matters  which are the subject  of  Article  12.4,  such  amounts  as
      required in accordance  with Article 12.4), (B) the defense of such Third
      Party Claim by the counsel  representing the Indemnifying Party does not,
      in  the  reasonable  judgment of  the  Indemnified  Party,  constitute  a
      conflict of interest under  the  applicable  cannons  or  rules  of legal
      professional ethics, (C) in such case as Pfizer or another of the  Pfizer
      Parties is the Indemnified Party, such Third Party Claim does not relate,
      directly  or  indirectly,  to  Geodon,  Xanax, or any other product under
      development  by  Pfizer,  its  Affiliates  or   licensees,  and  (D)  the
      Indemnifying  Party  makes reasonably adequate provision  to  ensure  the
      Indemnified Party of the ability of the Indemnifying Party to satisfy the
      full amount of any adverse  monetary  judgment  that  would reasonably be
      expected to result therefrom (the conditions set forth  in  clauses  (A),
      (B),  (C)  and  (D)  are  collectively  referred  to  as  the "Litigation
      Conditions").   In no event shall Organon have the right to  control  any
      Third Party Claim  to the extent such Third Party Claim relates, directly
      or indirectly, to Geodon,  Xanax,  or  any  other product (other than the
      Product) being developed or commercialized by  Pfizer,  its Affiliates or
      licensees.   If  both  Parties are Indemnifying Parties pursuant  to  co-
      indemnification obligations  under  Article 12.4 with respect to the same
      Third  Party  Claim, the Parties shall  determine  by  mutual  agreement,
      within twenty (20) days following their receipt of notice of commencement
      or assertion of  such Third Party


                                       67




      Claim (or such  lesser  period  of time as may be  required  to  properly
      respond to such  claim),  which Party  shall  assume the lead role in the
      defense thereof.  Should the Parties be unable to mutually agree on which
      Party  shall  assume the lead role in the  defense  of such  Third  Party
      Claim,  both  Parties  shall be entitled to  participate  in such defense
      through counsel of their respective  choosing;  provided that in the case
      of any Third  Party  Claim  with  respect to which (i) both  Parties  are
      Indemnifying  Parties pursuant to  co-indemnification  obligations  under
      Article  12.4 and (ii) the  Parties  are unable to agree upon which Party
      shall assume the lead role in the defense of such claim, then the Parties
      agree to discuss  strategies  for  defending  such claim and will, to the
      extent  reasonably  practicable,  coordinate  such defense  through their
      respective counsel.

            (iii) Within ten (10) days after the Indemnifying  Party  has given
      notice to the Indemnified Party of its intended exercise of its right  to
      defend  a  Third  Party Claim, the Indemnified Party shall give notice to
      the Indemnifying Party of any objection thereto based upon the Litigation
      Conditions.   If  the   Indemnified  Party  reasonably  so  objects,  the
      Indemnified Party shall continue  to defend the Third Party Claim, at the
      expense of the Indemnifying Party,  until  such time as such objection is
      withdrawn.   If  no such notice is given, or if  any  such  objection  is
      withdrawn, the Indemnifying Party shall be entitled, at its sole cost and
      expense, to assume and conduct such defense, with counsel selected by the
      Indemnifying Party  and  reasonably  acceptable to the Indemnified Party,
      until such time as the Indemnified Party  shall  give  notice that any of
      the  Litigation  Conditions,  in its reasonable judgment, are  no  longer
      satisfied.

            (iv)  During such time as the Indemnifying Party is controlling the
      defense of such Third Party Claim, the Indemnified Party shall cooperate,
      and  cause  its  Affiliates  and  agents  to  cooperate,  to  the  extent
      commercially reasonable, upon request  of  the  Indemnifying Party in the
      defense or prosecution of the Third Party Claim,  including by furnishing
      such records, information and testimony and attending  such  conferences,
      discovery  proceedings, hearings, trials or appeals as may reasonably  be
      requested by the Indemnifying Party.

            (v)   In the event that the Indemnifying Party fails to satisfy the
      Litigation Conditions or does not notify the Indemnified Party in writing
      of the Indemnifying Party's intent to defend any Third Party Claim within
      ten (10) days  after  notice  thereof, the Indemnified Party may (without
      further notice to the Indemnifying  Party)  undertake the defense thereof
      with  counsel  of  its  choice  and at the Indemnifying  Party's  expense
      (including  attorneys' fees and costs  and  expenses  of  enforcement  or
      defense).

            (vi)  The  Indemnifying Party or the Indemnified Party, as the case
      may be, shall have  the  right to join in (including the right to conduct
      discovery,  interview  and  examine  witnesses  and  participate  in  all
      settlement conferences), but not control, at its own expense, the defense
      of any Third Party Claim which  the  other Party is defending as provided
      in this Agreement.

            (vii) The Indemnifying Party, if  it shall have assumed the defense
      of any Third Party Claim as provided in this Agreement, shall not consent
      to a settlement of, or the entry of any judgment  arising  from, any such
      Third  Party  Claim  without the prior written consent of the Indemnified
      Party (which consent shall not be unreasonably withheld or delayed).  The
      Indemnifying Party shall  not,  without  the prior written consent of the
      Indemnified Party, enter into any compromise  or settlement which commits
      the Indemnified Party to take, or to forbear to  take,  any  action.  The
      Indemnified  Party shall have the sole and exclusive right to settle  any
      Third Party Claim,  on  such  terms and conditions as it deems reasonably
      appropriate, to the extent such  Third  Party Claim involves equitable or
      other non-monetary relief, and shall not  have  the  right to settle such
      Third Party Claim to the extent such Third Party Claim  involves monetary
      damages without the prior written consent of the Indemnifying Party.

            (viii) The Indemnified Party shall be entitled to reimbursement for
      all  costs and expenses, including attorneys' fees and costs and expenses
      of enforcement  or  defense, on an "as incurred" basis.  The Indemnifying
      Party will reimburse  the  Indemnified  Party  for  such  amounts  within
      fifteen  (15)  days after receiving an invoice from the Indemnified Party
      therefor.

      12.6 Losses.  For purposes of Articles 11 and 12, "Losses" shall mean any

the items referred in clauses (a) and (b) above, any and all costs and expenses
(including  reasonable  attorneys'  fees  and  all  other  expenses  reasonably
incurred in investigating, preparing or defending any litigation or proceeding,
commenced or threatened). Notwithstanding anything to the contrary, the Parties
understand and agree that no Losses for which one Party has agreed to indemnify
any  of the  the  other  Party  under  this  Agreement  shall  be  included  in
Development  Costs,  Cost of Goods or Marketing  Costs or shall be applied as a
reduction in the calculation of Net Sales.

      12.7 Limitation on Damages. IN NO EVENT SHALL PFIZER OR ORGANON BE LIABLE
FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING,  WITHOUT
LIMITATION,  LOSS OF PROFITS)  SUFFERED  BY ANY  ORGANON  PARTIES OR ANY PFIZER
PARTIES,  RESPECTIVELY UNDER THE ALLIANCE AGREEMENTS,  EXCEPT (A) TO THE EXTENT
OF ANY SUCH DAMAGES  PAID TO A THIRD PARTY AS PART OF A THIRD PARTY CLAIM,  AND
(B) FOR PURPOSES OF INDEMNIFICATION  PURSUANT TO ARTICLE 12, IN THE EVENT OF AN
INTENTIONAL  AND WILLFUL BREACH IN BAD FAITH OF ANY  REPRESENTATION,  WARRANTY,
COVENANT  OR  AGREEMENT  BY  ORGANON  OR  PFIZER  (AS THE  CASE MAY BE) OF THIS
AGREEMENT,  AND (C) AS PROVIDED  IN ARTICLE  12.8  BELOW.  EXCEPT AS  EXPRESSLY
PROVIDED IN THIS AGREEMENT,  INDEMNIFICATION  PURSUANT TO THIS ARTICLE 12 SHALL
BE THE SOLE AND EXCLUSIVE REMEDY (WHETHER BASED ON CONTRACT,  TORT OR ANY OTHER
LEGAL THEORY) AVAILABLE TO ORGANON OR PFIZER FOR ANY MISREPRESENTATION UNDER OR
BREACH OF THIS AGREEMENT.

      12.8  Available  Damages.   Notwithstanding   anything  to  the  contrary
contained in this  Agreement,  in the case of any claim by Pfizer  alleging any
breach of this  Agreement  by Organon,  the  following in each case will not be
considered  as  constituting  special,  incidental,  indirect or  consequential
damages under this Agreement:  (x) payments due to Pfizer pursuant to Article 6
or Article 9 of this Agreement, and (y) Losses as and to the extent such Losses
aggregate  up to the sum of all  amounts  previously  paid to Organon by Pfizer
under any of the Alliance Agreements.

                                  ARTICLE 13


                             TERM AND TERMINATION

      13.1 Term.  Unless  terminated  sooner pursuant to this Article 13 hereof

Country-by-Country basis in each Country of the Territory for a period equal to
the longer of (A) fifteen  (15) years  following  Launch of the Product in such
Country,  and (B) such date the Product is no longer  embraced within any Valid
Claim under Organon Patent Rights in such Country (the "Term").

      13.2 Bilateral Termination.  This Agreement may be terminated at any time
by written consent of each of the Parties.  Such  termination will be effective

      13.3 Material  Default.  Organon shall have the rights set forth below in
this  Article  13.3 by notice to Pfizer,  and Pfizer  shall have the rights set

            (i)   Upon  Organon's  notice  to Pfizer that a Material Default by
      Pfizer has occurred, the Parties will  meet  to  discuss  in  good  faith
      whether a plan to remedy the Material Default can be mutually agreed.  If
      the  Parties  fail  to so agree within thirty (30) days after the date of
      such notice, Article  13.3(ii)  below  shall  apply.  Notwithstanding the
      foregoing provisions of this Article 13.3(i),


                                       69




      in the case of a payment  default,  the  provisions  of Article  13.3(ii)

      written notice, terminate this Agreement, provided, however, that in case
      of a default of a payment  obligation  such  notice  will  lapse  without
      effect if Pfizer cures such default within thirty (30) days after receipt
      of  such  notice.   Organon may give the notice specified in this Article
      13.3(ii) concurrently  with  the  notice specified in Article 13.3(i) and
      shall not give the notice specified  in  this Article 13.3(ii) later than

            (iii) Upon Pfizer's notice  to  Organon  that a Material Default by
      Organon  has  occurred, the Parties will meet to discuss  in  good  faith
      whether a plan to remedy the Material Default can be mutually agreed.  If
      the Parties fail  to  so  agree within thirty (30) days after the date of
      such notice, Article 13.3(iv)  below  will  apply.   Notwithstanding  the
      foregoing  provisions of this Article 13.3(iii), in the case of a payment
      default, the provisions of Article 13.3(iv) below shall apply without any

      Material  Default  by Organon, Pfizer may, upon ninety  (90)  days  prior
      notice, terminate this  Agreement,  provided,  however, that in case of a
      default of a payment obligation such notice will  lapse without effect if
      Organon cures such default within thirty (30) days  after receipt of such
      notice.   Pfizer may give the notice specified in this  Article  13.3(iv)
      concurrently with the notice specified in Article 13.3(iii) and shall not
      give the notice  specified in this Article 13.3(iv) later than sixty (60)
      days after the date of the notice specified in Article 13.3(iii).

            (v)   Notwithstanding  Organon's  right of termination described in
      this  Article 13.3, Organon acknowledges that  it  shall  have  no  claim
      whatsoever against Pfizer under this Agreement, and no right to terminate
      this Agreement,  for  any  breach  or  alleged  breach  by  Pfizer of the
      Alliance  Agreements  other  than  this Agreement, and that, under  those
      circumstances, this Agreement shall  remain  in  full  force  and  effect
      according to its terms.

      13.4 Change in Control.  Organon may terminate  this Agreement by written

            the FDA,  and (y)  Regulatory  Approval  of the  Product  in the US
            Territory,  in  the  event  that  Pfizer,  in the  exercise  of its

            Studies under the  Development  Plan,  concludes in good faith that
            [CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
            TO THE SECURITIES AND EXCHANGE  COMMISSION] will not be, or has not
            been, as applicable, achieved at the time of such approvable letter

            TO THE SECURITIES AND EXCHANGE COMMISSION]

            (ii)  Termination for [CONFIDENTIAL INFORMATION  HAS  BEEN  OMITTED
      AND  FURNISHED SEPARATELY TO THE SECURITIES AND EXCHANGE COMMISSION]  and
      [CONFIDENTIAL  INFORMATION  HAS  BEEN OMITTED AND FURNISHED SEPARATELY TO
      THE SECURITIES AND EXCHANGE COMMISSION];  at  Will.  Pfizer may terminate
      this Agreement as follows:

            SEPARATELY  TO THE  SECURITIES  AND  EXCHANGE  COMMISSION],  or the
            endpoints  described  in  Schedule  13.5(ii)(a),  with  respect  to
            [CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY
            TO THE SECURITIES AND EXCHANGE COMMISSION] or

            after the third anniversary of the first Launch of a Product in the
            US  Territory.  Pfizer shall be entitled to submit the above notice
            from  time to time in its  absolute  and sole  discretion.  Without
            limiting the foregoing:

                        (1) if  the  effective date of termination  pursuant to
                  this Article 13.5(ii)(b)  is expected to fall after the first
                  Launch of the Product in the  US  Territory  but prior to the
                  first anniversary of such Launch, then Organon  may,  at  its
                  option, on written notice to Pfizer given no more than thirty
                  (30)  days  after the date of Pfizer's notice of termination,
                  (A)  shorten  the  applicable  notice  period  so  that  this

                  terminates on the first anniversary of such Launch; and

                        (2) if  the  effective date of termination  pursuant to
                  this Article 13.5(ii)(b)  is  expected  to  fall prior to the
                  first Launch of the Product in the US Territory, then Organon
                  may, at its option, on written notice to Pfizer given no more
                  than  thirty (30) days after the date of Pfizer's  notice  of
                  termination, extend the effective date of such termination by
                  an  additional   one  hundred  and  eighty  (180)  days  (the
                  "Additional Notice  Period"),  during  which time Pfizer will
                  continue its role in connection with the clinical development
                  of the Product in the same manner as it  was  conducting such
                  clinical development activities prior to giving  such  notice
                  of  termination, and will continue to be responsible for  its
                  share of any Development Costs incurred or accrued during the
                  Additional Notice Period related to such clinical development
                  activities  applicable  pursuant to Article 4.4 and with such
                  cost sharing percentage in  effect  at  the  time of Pfizer's
                  notice  of termination (the "Additional Development  Costs"),
                  but Pfizer  will  be relieved of all of its other obligations
                  (including payment obligations) under this Agreement.  Pfizer
                  will  provide  Organon  with  a  report  setting  forth  such
                  Additional Development Costs within sixty (60) days after the
                  end of the Additional Notice Period.

      13.1 Bankruptcy.  Each  Party may, in  addition  to  any  other  remedies
available to it by law or in equity,  exercise  the  rights  set forth below by
written notice to the other Party, which in the case of Organon, shall refer to
the  Organon  Group  (the "Insolvent Party"), in the event the Insolvent  Party
shall  have  become insolvent  or  bankrupt,  or  shall  have  made  a  general
assignment for the benefit of its creditors, or there shall have been appointed
a trustee or receiver  of  the Insolvent Party or for all or a substantial part
of its property, or any case  or  proceeding shall have been commenced or other
action  taken  by  or against the Insolvent  Party  in  bankruptcy  or  seeking
reorganization, liquidation,  dissolution,  winding-up arrangement, composition
or  readjustment  of  its  debts  or  any other relief  under  any  bankruptcy,
insolvency, reorganization or other similar  act or law of any jurisdiction now
or hereafter in effect, and any such event shall  have continued for sixty (60)
days undismissed, unbonded and undischarged.  All rights  and  licenses granted
under  or  pursuant  to  this  Agreement  by Organon and Pfizer are, and  shall
otherwise  be  deemed  to  be,  for purposes of  Article  365(n)  of  the  U.S.
Bankruptcy Code, licenses of rights to "intellectual property" as defined under
Article 101 of the U.S. Bankruptcy Code.  The Parties agree that the Parties as
licensees  of such rights under this  Agreement  shall  retain  and  may  fully
exercise all of their rights and elections under the U.S. Bankruptcy Code.  The
Parties further  agree  that,  in the event of the commencement of a bankruptcy
proceeding by or against either Party under the U.S. Bankruptcy Code, the other
Party shall be entitled to a complete  duplicate  of (or complete access to, as
appropriate)  any  such  intellectual  property  and all  embodiments  of  such
intellectual property, and same, if not already in  their  possession, shall be
promptly  delivered  to  it  (i)  upon  any  such commencement of a  bankruptcy
proceeding upon its written request therefore, unless the Party subject to such
proceeding  elects to continue to perform all of  its  obligations  under  this
Agreement or  (ii) if not delivered under (i) above, upon the rejection of this
Agreement by or  on behalf of the Party subject to such proceeding upon written
request therefore by the other Party.

      herein  during the  Post-Termination  Period  described  below,  provided,
      however,  that,  such royalty  shall  terminate  when the aggregate of all

      The Parties understand and agree that all payments  by  Organon to Pfizer
      of the royalties required under this Article 13:  (x) shall be calculated
      and made in accordance with the procedures set forth in this  Article  13
      and  Article 9 as if this Agreement had not otherwise terminated, and (y)
      shall  be  calculated  and  apply, on a Country-by-Country basis, in each
      Country  of the Territory for  the  period  ("Post-Termination  Period"),
      subject to  the  limitation  set forth in Article 13.9(iv), commencing on
      the effective date of termination  and ending on the later of (A) fifteen

      embraced  within any Valid  Claim  under  Organon  Patent  Rights in such
      Country (assuming all of the defined terms and related provisions used in
      this clause (y) survived  termination of this  Agreement);  and (z) shall
      remain  due  and  owing   without   regard  to  the   expiration  of  the

      13.10 Survival of Rights and Obligations  upon Termination or Expiration.
Upon expiration or termination of this Agreement, the rights and obligations of
the Parties hereunder shall cease, except as follows:

            (i)   The obligations  set  forth  in  Article 14 (Confidentiality)
      shall survive for the period provided therein;

            (ii)  The  obligations  set  forth  in  Article   11  (Intellectual
      Property),  Article  12  (Claims), Article 13 (Term and Termination)  and
      Article 15 (Dispute Resolution) shall survive without limitation.

            (iii) The Parties shall not be relieved of any obligations accruing
      prior to such applicable expiration  or  termination under this Agreement
      (including without limitation all payment obligations which relate to all
      periods on or prior to such expiration or termination), other than as set
      forth in Article 8; and

            (iv)  The terminated Party under this Article 13 shall be obligated
      to pay any amounts otherwise reimbursable or due to the other Party under
      this Agreement in accordance with the terms  hereof,  including,  without
      limitation,  pursuant to the then most current, as applicable Development
      Plan or Global  Marketing  Plan, but only to the extent such amounts were
      actually incurred or accrued  by  either  Party  under  any  Third  Party
      contract  arising  in  accordance  with  the  terms  of  such Third Party
      contract prior to the date of the notice of termination.   The terminated
      Party under this Article 13 shall, at the other Party's expense,  use its
      reasonable  efforts  to  assist  in  the  transition of any activities or
      obligations which were being performed by such  Party  to the other Party
      or its designee.

            (v)   Upon  termination  of  this  Agreement by Pfizer  pursuant  to
      Article 13.3, 13.4 or 13.5, the license and the other rights granted to it
      under this Agreement shall terminate and it shall have no further right to
      develop, use, sell, offer for sale, import  and  have imported Products in
      the  Territory.   In  such case, where applicable the  Regulatory  Filings
      and/or Regulatory Approvals  shall be assigned and transferred promptly by
      Pfizer to Organon or any other  party designated by Organon. This transfer
      upon termination shall be arranged  promptly,  but in any event within one
      hundred and eighty (180) days after termination.

            (vi)  Upon termination of this Agreement,  Pfizer  shall assign, and
      Organon shall accept assignment of, all of Pfizer's rights and obligations
      under any tolling or similar agreement between Pfizer or its Affiliate and
      [CONFIDENTIAL INFORMATION HAS BEEN OMITTED AND FURNISHED SEPARATELY TO THE
      SECURITIES  AND  EXCHANGE  COMMISSION]  or  its  Affiliate, regarding  the
      manufacture  of the Product, and Organon shall purchase  from  Pfizer,  at
      Pfizer's book  value,  any  equipment  or other similar items purchased by
      Pfizer directly in connection with Pfizer's or its Affiliate's obligations
      under  the  Production Agreements installed  and  primarily  used  in  the
      manufacture of the Compound and/or Product.

      13.11 Consequences of a Change in Control.

            (i)   (a)   If at any time during any Term of this Agreement, there
      shall occur a Change  in  Control  with  respect to Organon, then, within
      forty-five (45) days after the closing or  other  effective  date of such
      event Pfizer may by written notice delivered to Organon elect  to cause a
      valuation of the entire interests, rights and obligations of Pfizer under
      this  Agreement  but


                                       75




      excluding in all cases the Excepted  Rights (the "Pfizer  Interest")  and
      the entire  interests,  rights  and  obligations  of  Organon  under this
      Agreement  but  excluding in all cases the Excepted  Rights (the "Organon
      Interest")  under the  provisions of this Article  13.11.  Within 15 days
      following such  valuation,  Pfizer shall make the further  election to do
      any of the  following:  (1)  sell  to  Organon  the  Pfizer  Interest  in
      accordance with Article  13.11(ii),  or (2) purchase the Organon Interest
      in accordance with Article 13.11(ii),  or (3) elect not to terminate this
      Agreement (in which case,  from and after the closing or other  effective
      date of the Change in Control,  Pfizer  shall have final  decision-making
      authority  for all  Consensus  Matters  with  respect  to  manufacturing,
      Product  positioning  and,  prior  to first  filing  an  application  for
      Regulatory Approval in a Major Market Country, regulatory matters) or (4)
      terminate this Agreement in accordance with Article 13.4.

                  (b)  If  at any time during the Term of this Agreement, there
      shall occur a Change in  Control  with  respect  to  Pfizer,  then within
      forty-five  (45) days after the closing or other effective date  of  such
      event Organon  may by written notice delivered to Pfizer elect to cause a
      valuation of the entire interests, rights and obligations of the "Organon
      Interest"  and the  Pfizer  Interest  under  the  provisions  of  Article
      13.11(ii).   Within  15 days following such valuation, Organon shall make
      the further election to  do any of the following:  (1) sell to Pfizer the
      Organon Interest in accordance with Article 13.11(ii) or (2) purchase the
      Pfizer Interest in accordance  with Article 13.11(ii) or (3) elect not to
      terminate this Agreement (in which  case,  from  and after the closing or
      other effective date of the Change in Control, Organon  shall  have final
      decision-making  authority  for  all  Consensus  Matters with respect  to
      manufacturing,  Product  positioning  and,  prior  to  first   filing  an
      application for Regulatory Approval in a Major Market Country, regulatory
      matters) or (4) terminate this Agreement in accordance with Article 13.4.

            (ii)  (a)   The price (the "Organon Price" and the "Pfizer  Price",
      respectively) to be  paid  to purchase the Organon Interest or the Pfizer
      Interest, as the case may be, under this Agreement, shall be conclusively
      determined by two internationally  recognized  investment  banking firms,
      one of which shall be retained and paid by Organon and one of which shall
      be retained and paid by Pfizer; provided that, if either Party  fails  to
      deliver  notice  to  the  other  Party  of its selection of an investment
      banking firm within twenty (20) days after notice by the other Party that
      it has selected an investment banking firm  (which  notice shall identify
      such firm), the determination shall be rendered by the  single investment
      banking  firm  so  selected  (whose  fees, in such case, shall  be  borne
      equally by the Parties).  Organon and  Pfizer  shall promptly notify each
      other of its respective selection.  The investment banking firms selected
      in  accordance  with  the  foregoing procedure shall  each  independently
      determine the fair market value  of  the  Organon Interest and the Pfizer
      Interest  as  contained in written reports prepared  in  accordance  with
      Article 13.11 and  shall  submit  their  determinations  of such value to
      Organon  and Pfizer within thirty (30) days after their selection,  which
      value shall  be  an  amount  that,  on  the  basis  of  market  and other
      conditions  prevailing at such time, could reasonably be expected  to  be
      paid therefor  by  a Third Party in an arm's-length transaction, assuming
      that the buyer and seller  are  under  no  compulsion  to buy or sell; it
      being further understood and agreed that the Organon Price and the Pfizer
      Price shall be the same except for differences resulting from the ability
      of Pfizer to commercialize the Product in Pfizer Exclusive  Countries and
      resulting from the ability of Organon to commercialize the Product in the
      Organon Exclusive Countries .

                  (b)  The Organon Price or the Pfizer Price, as the  case  may
      be,  shall  be the amount equal to the sum of such fair market values for
      the Organon Interest  or the Pfizer Interest, respectively, determined by
      each investment banking firm divided by two (2) or if only one investment
      banking firm is involved  as  contemplated  above,  such  individual fair
      market  values,  except  that  if there is more than a ten percent  (10%)
      difference between such values for  either  the  Organon  Interest or the
      Pfizer Interest, as applicable, a third investment banking firm (which is
      independent  of  both  Organon  and  Pfizer and has not been retained  by
      either  Pfizer  or Organon or any of their  respective  Affiliates  as  a
      financial advisor  within  the two (2) prior years) selected by the first
      two investment banking firms  shall  determine  such fair market value by
      selecting  one  (but  only  one  (1))  of  the  two (2) pairs  of  values
      previously determined by the first two investment


                                       76




      banking firms pursuant to this Article 13.11(ii).  The cost of such third
      investment  banking firm shall be borne  one-half by Organon and one-half
      by Pfizer.

            (iii) Any purchase  and  sale  of  an  Organon  Interest  or Pfizer
      Interest  pursuant  to  this Article 13.11 shall be transferred free  and
      clear of all liens and other  encumbrances  and  shall  be consummated at
      closing at the principal offices of Pfizer, in the case of an event under
      Article  13.11(i)(a), or Organon, in the case of an event  under  Article
      13.11(i)(b),  on a business day within forty-five (45) days following the
      last determination of the Organon Price and the Pfizer Price, as the case
      may be, and upon  at  least  5  business  days' prior notice by Pfizer or
      Organon,  as  the  case may be, to the other Party;  provided  that  such
      period shall be extended for ninety (90) additional days, or such shorter
      period of time, as shall  be  necessary  in  order  to  obtain  requisite
      governmental  or  regulatory  approvals with respect to such transaction.
      At such closing, the buying Party shall pay the selling Party the Organon
      Price or the Pfizer Price, as the  case  may  be,  by  wire  transfer  of
      immediately available funds.

            (iv)  Upon  the  closing  of  the transactions contemplated by this
      Article  13.11,  the  Parties  shall use  their  respective  commercially
      reasonable efforts to perform such  matters   and  to  execute such other
      documents  as  are necessary to transfer all of the Organon  Interest  or
      Pfizer Interest, as the case may be, to (x)  the buying Party in order to
      ensure that the  buying  Party or its designee shall be able to enjoy the
      benefits contemplated by this  Agreement,  and  (y)  the selling Party in
      order  to  release  the  selling  Party  from all obligations  under  the
      Agreement effective as of the time of such  sale (other than with respect
      to any obligations under this Agreement then due and owing and other than
      with respect to all obligations, whether or not  due  and owing, pursuant
      to  Article  12,  all  of which shall remain obligations of  the  selling
      Party).  Pfizer agrees that,  if it is the buyer of the Organon Interest,
      Pfizer  shall not for a period of  eighteen  months  following  any  such
      purchase  terminate any of the manufacturing activities for which Organon
      has contracted  Diosynth  to  perform in accordance with the terms of the
      Alliance Agreements.   As used herein, "Excepted Rights" means any rights
      of  any  of  the  Parties  to  receive   payments  under  this  Agreement
      immediately prior to the date of any closing contemplated by this Article
      13.11  and shall, in all events, exclude all  intellectual  property  and
      other rights  which  relate  to Geodon and any changes to or improvements
      thereon.

      13.12  Standstill.  Pfizer  hereby  agrees  that,  during the  Standstill
Period,  unless  the  restrictions  set forth in this  Article  13.12 have been
specifically  waived in writing by Organon,  Pfizer  shall not (and shall cause
its direct and indirect subsidiaries not to):

            (i)   acquire or agree or make any public  announcement to acquire,
      directly  or indirectly, by purchase or otherwise,  ownership  (including
      beneficial  ownership)  of  (a)  more  than  five  (5%)  percent  of  the
      outstanding voting securities, or direct or indirect rights or options to
      acquire more than five (5%) percent of the outstanding voting securities,
      of  Organon  or  any successor, or (b) more than five (5%) percent of the
      outstanding voting securities, or direct or indirect rights or options to
      acquire more than five (5%) percent of the outstanding voting securities,
      of  Akzo Nobel N.V.  for  so  long  as  Akzo  Nobel  N.V.  is a Parent of
      Organon, or (c) all or substantially all of the assets of Organon  or any
      successor  (other  than  with respect to the matters contemplated by this
      Agreement); or

            (ii)  engage  in  any   "solicitation"  (as  soliciting  party)  of
      "proxies" (as such terms are used  in  the  proxy rules of the Securities
      and Exchange Commission) or consent to vote any voting securities of Akzo
      Nobel N.V. or, commencing at such time as Akzo  Nobel  N.V.  is no longer
      the Parent of Organon, Organon or any successor; or

            (iii) submit   a  proposal  for,  or  offer  of  (with  or  without
      conditions), any extraordinary transaction involving all or substantially
      all of the assets of Organon or Akzo Nobel N.V., other


                                       77




      than pursuant to a confidential  communication to management or the Board
      of Management of Akzo Nobel N.V.; or

            (iv)  make  a  public  announcement  with respect  to  any  of  the
      foregoing; or


            (v)   form, join or in any way participate in a "group" (as defined
      under the 1934 Act) with respect to any acquisition by any such person of
      securities of Organon or enter into any discussions  or arrangements with
      any Third Party with respect to any of the foregoing prohibited matters.


            (vi)  Notwithstanding  the  foregoing  provisions of  this  Article
      13.12, neither Pfizer nor any of its Affiliates will be subject to any of
      the restrictions set forth above in this Article  13.12:   (a) if Organon
      or  Akzo  Nobel N.V. announces publicly that it is seeking any  purchaser
      for a controlling  interest  in  its business or enters into negotiations
      for the sale of such controlling interest which negotiations are publicly
      announced, or (b) if it is publicly  announced that (1) another person or
      group  has offered or proposed to acquire,  directly  or  indirectly,  by
      purchase, tender offer, merger, consolidation or otherwise, a controlling
      interest  in  Organon  or  Akzo  Nobel  N.V.  or,  alternatively,  assets
      representing  at  least thirty (30%) percent of the market capitalization
      of Akzo Nobel N.V.  or  Organon,  or  (2)  that Akzo Nobel or Organon has
      entered into an agreement in principle or definitive  agreement providing
      for a transaction described in the immediately preceding  clause  (1), or
      (c)  if  a  party  unaffiliated  with Akzo Nobel N.V. shall have publicly
      announced an intention to seek a change of control of the governing board
      of Akzo Nobel N.V through the solicitation  of  proxies  or otherwise, or
      (d)  with respect to the matters described in the last sentence  of  this
      Article  13.12,  or  (e) with respect to any acquisition of any assets or
      securities of Organon  or any Parent, as debtor, in a transaction subject
      to  the  approval  of the United  States  Bankruptcy  Court  pursuant  to
      proceedings under the  United States Bankruptcy Code, or (f) with respect
      to matters  required or  permitted by this Agreement. For the purposes of
      this Article the term "controlling  interest"  shall mean the possession,
      through ownership of voting securities or otherwise,  of  the  ability to
      direct  the  management  and affairs of Akzo Nobel N.V. or Organon,  and,
      without limitation, shall  be  conclusively presumed to be present in the
      case of the direct or indirect ownership  of  a  majority  of  the voting
      securities  and/or  equity  interests  of Akzo Nobel N.V. or Organon,  as
      applicable, without precluding the existence  of  control  in the case of
      the ownership of a lesser amount of such securities.


            (vii) Notwithstanding  anything  to the contrary contained  herein,
      the prohibitions set forth in this Article  13.12  shall not apply to (a)
      any investment in any securities of Organon or Akzo  Nobel  N.V. by or on
      behalf  of  any  pension  or  employee  benefit  plan or trust, including
      without  limitation  (1)  any direct or indirect interests  in  portfolio
      securities held by an investment  company registered under the Investment
      Company  Act  of  1940,  as  amended,  or  (2)  interests  in  securities
      comprising part of a mutual fund or broad  based,  publicly traded market
      basket or index of stocks approved for such a plan or trust in which such
      plan or trust invests; or (b) securities of Organon  or  Akzo  Nobel N.V.
      held by a Person acquired by Pfizer on the date such Person first entered
      into an agreement to be acquired by Pfizer or acquired after such  Person
      was  acquired  by Pfizer pursuant to an agreement requiring (but only  to
      the extent requiring)  such  Person  to  acquire  such  securities, which
      agreement  was  in effect on the date such Person first entered  into  an
      agreement to be acquired  by  Pfizer,  or  (c)  any  sale  by  Pfizer  of
      securities in a tender or exchange offer initiated by a Person other than
      Pfizer  and/or any vote securities owned by it in favor of or against any
      such sale.

                                  ARTICLE 14


                                CONFIDENTIALITY




      14.1 Treatment of Confidential Information.  Subject to the provisions of
Article 11, and  further  subject to the terms of this  Article 14,  during the
Term and for a period of five (5) years  thereafter,  each of the Parties shall
maintain Confidential  Information of the other Party in confidence,  and shall
not disclose, divulge or otherwise communicate such Confidential Information to
others (except for agents and advisors under obligations of confidentiality) or
use it  for  any  purpose  other  than  in  connection  with  the  development,
manufacture, marketing, promotion, distribution or sale of the Product or Xanax
and any  improvements  or changes  thereto,  or as otherwise  permitted in this
Agreement and the other Alliance Agreements,  and each Party agrees to exercise
reasonable efforts to prevent and restrain the unauthorized  disclosure of such
Confidential  Information  by  any  of  its  directors,   officers,  employees,
consultants,  subcontractors,  licensees or agents,  which  reasonable  efforts
shall  be at  least  as  diligent  as  those  generally  used by such  Party in
protecting its own confidential and proprietary information.

      14.2 Right to  Disclose.  To the  extent it is  reasonably  necessary  or
appropriate  to fulfill  its  obligations  or  exercise  its rights  under this
Agreement or any rights which survive termination or expiration hereof, each of
the Parties may consistent with its obligations  under the Alliance  Agreements
disclose  Confidential  Information  to its  Affiliates,  consultants,  outside
contractors,  clinical  investigators  or other Third Parties on a need to know
basis and on the condition that such entities or persons agree in writing:

            (i)   to  keep  the Confidential Information confidential  for  the
      same time periods and to  a  comparable extent as the disclosing Party is
      required to keep the Confidential Information confidential; and

            (ii)  to use the Confidential Information only for such purposes as
      the disclosing Party is entitled to use the Confidential Information.

      14.3 Required Disclosures.

            (i)   To the extent, if  any,  that a Party concludes in good faith
      that it is required to file or register  this  Agreement  (or  any  other
      Alliance  Agreement)  or  a  notification  thereof  with any Governmental
      Authority,  including without limitation the US Securities  and  Exchange
      Commission, or  the  US  Federal  Trade  Commission,  in  accordance with
      applicable  Laws, such Party may do so.  The other Party shall  cooperate
      in such filing or notification and shall execute all documents reasonably
      required in connection  therewith.   In  such situation, the Parties will
      request  and  will use their reasonable efforts  to  obtain  confidential
      treatment of all  proprietary and other commercially-sensitive provisions
      of the Agreement (or other Alliance Agreement, as applicable), all to the
      extent permitted by Law.  The Parties shall promptly inform each other as
      to  the  activities or  inquiries  of  any  such  Governmental  Authority
      relating to  the  Alliance  Agreements, and shall cooperate to respond to
      any request for further information therefrom.

            (ii)  Each Party or its  Affiliates  may disclose such Confidential
      Information  to  Governmental  Authorities  to  the   extent   that  such
      disclosure (a) is reasonably necessary to obtain Regulatory Approvals; or
      (b)  is  otherwise legally required.  Without limiting the generality  of
      the foregoing  and  notwithstanding  anything in this Agreement or in any
      other  agreement  to  the  contrary,  each   Party  (and  each  employee,
      representative, or other agent of each Party)  may  (but  is not required
      to) disclose to any and all persons, without limitation of  any kind, the
      tax treatment and tax structure of the transaction contemplated  by  this
      Agreement  and  the  other  agreements  and instruments to be executed in
      connection  herewith,  as  of  the earlier of  (x)  the  date  of  public


                                       79




      announcement of discussions relating  to the transactions contemplated by
      this Agreement, (y) the date of public announcement of such transactions,
      or (z) the date of the execution of the  agreement  to  enter  into  such
      transactions; provided, however, that such disclosure shall be prohibited
      to  the  extent  required  to comply with any applicable federal or state
      securities laws; and provided further that the confidentiality provisions
      of this agreement and the other  agreements  and  instruments relating to
      the  transactions  between  the  Parties  shall  continue   to  apply  to
      information that is irrelevant to understanding the tax treatment  or tax
      structure of the transactions contemplated hereby and thereby (including,
      without  limitation, the names and other identifying details of any Party
      to this Agreement).   The  preceding  sentences are intended to cause the
      transaction contemplated herein to be treated  as not having been offered
      under  conditions  of  confidentiality for purposes  of  Article  1.6011-
      4(b)(3)  (or  any successor  provision)  of  the  Internal  Revenue  Code
      ("Code") and shall be construed in a manner consistent with such purpose.
      Each Party recognizes  that  the  privilege  each has with respect to the
      confidentiality of the transaction contemplated  by this Agreement or the
      confidentiality   of  a  communication  relating  to  such   transaction,
      including a confidential  communication  with  its  attorney  or  with  a
      federally  authorized tax practitioner under Article 7252 of the Code, is
      not intended to be waived by the foregoing.

      14.4 Return of  Confidential  Information.  Upon any  termination of this
Agreement and the other Alliance  Agreements,  each Party shall promptly return
to the  other  Party  all  written  Confidential  Information,  and all  copies
thereof,  of such other  Party,  except  that each Party may retain one copy of
such  Confidential  Information  solely to discern its  continuing  obligations
under this Article 14.


                                  ARTICLE 15


                              DISPUTE RESOLUTION

      15.1  Governing Law.  The validity, construction  and performance of this
Agreement will be governed by and construed in accordance  with the substantive
laws of the State of New York with regard to principles of conflict of laws.

      15.2  Negotiation.  The  Parties  will  attempt  in good faith to resolve
promptly  any  dispute  arising  out  of  or  relating  to  this  Agreement  by
negotiation. If the matter can not be resolved in the normal course of business
any  interested  Party  may give the  other  Party  written  notice of any such
dispute not  resolved,  after which the dispute will be referred to more senior
executives of both Parties,  who will likewise  attempt to resolve the dispute.
If the dispute has not been resolved by negotiation  within thirty (30) days of
the disputing  Party's  written  notice,  or if the Parties fail to meet within
twenty (20) days as from the date of such  notice,  either Party may commence a
mediation pursuant to Article 15.3 below.

      15.3  Mediation.  If the  dispute has not been  resolved  by  negotiation
within  thirty (30) days of the disputing  Party's  written  notice,  or if the
Parties fail to meet within  twenty (20) days as from such notice,  the Parties
will  attempt  to  settle  the  dispute  by non-  binding  mediation  under the
supervision  of and in  accordance  with the CPR  Model  Mediation  Procedures.
Unless otherwise agreed to by the Parties,  the CPR will appoint an independent
mediator. The language of mediation will be English and the mediation will take
place in New York, New York. If within thirty (30) days of the  commencement of
mediation  in  accordance  with the  above  procedures,  the  Parties  have not
resolved their dispute, then either Party may commence a Proceeding pursuant to
Article 15.4 below.

      15.4  Jurisdiction.  With  respect to any  Proceeding,  each Party hereto
irrevocably (i) subject to the final sentence of this Article 15.4,  agrees and
consents  to be  subject to the  exclusive  jurisdiction  of the United  States
District  Court for the  Southern  District  of New York or any New York  state
court sitting in New York, New York,  United States of America (any such court,
the "New York  Court") and (ii) waives any  objection  which it may have at any
time to the  laying  of venue of any  Proceeding  brought  in any such New York
Court  and  waives  any claim  that  such  Proceeding  has been  brought  in an
inconvenient forum


                                       80




and further waives the right to object,  with respect to such Proceeding,  that
such Court does not have any jurisdiction over such Party.  Notwithstanding the
foregoing:  (i) each Party  shall be  entitled  to seek  injunctive  relief and
specific performance (including but not limited to any relief or recovery under
any  Alliance  Agreement)  in any  court in the  world,  and (ii) if the  Court
adjudicating  such Proceeding  refuses for any reason to exercise  jurisdiction
over the dispute,  either Party shall be free to bring such  Proceeding  in any
other  Court in New York State as  provided  above and, in the event such other
Court(s)  refuse  for any reason to  exercise  jurisdiction  over the  dispute,
either Party shall be free to bring such Proceeding in any other court. Organon
shall at all times  maintain  an agent for  service  of  process  and any other
documents  in  proceedings  in New York,  New York,  and hereby  designates  CT
Corporation  System, with offices located at 111 Eighth Avenue, 13th Floor, New
York, New York 10011, as its agent.  Organon shall promptly provide Pfizer with
written  notice of any change in the  identity  of such  agent.  Any  pleading,
judgment  or other  notice of legal  process  shall be  sufficiently  served on
Organon if delivered to its agent at its then-current address.


                                  ARTICLE 16


                                 MISCELLANEOUS

      16.1 Force Majeure.  Neither Party shall be held liable or responsible to
the  other  Party  nor be  deemed  to have  defaulted  under or  breached  this
Agreement for failure or delay in fulfilling or performing any Term, other than
an obligation to make payments hereunder,  when such failure or delay is caused
by  or  results  from  fire,   floods,   embargoes,   government   regulations,
prohibitions  or  interventions,  war,  acts of war (whether war be declared or
not),  insurrections,  riots, civil commotions,  acts of God or any other cause
beyond the reasonable  control of the affected  Party to  anticipate,  prevent,
avoid or  mitigate  (a "Force  Majeure  Event");  provided,  however,  that any
failure or delay in  fulfilling  a term shall not be  considered  a result of a
Force  Majeure Event if it arises from a failure of Pfizer or Organon to comply
with applicable laws and regulations.

      16.2 Further  Assurances.  Each Party hereto agrees to perform such acts,
execute such further instruments,  documents or certificates,  and provide such
cooperation  in proceedings  and actions as may be reasonably  requested by the
other  Party in order to carry out the  intent and  purpose of this  Agreement,
including  without  limitation  the  registration  or recordation of the rights
granted hereunder.

      16.3  Notices.  Any notice  required or permitted  to be given  hereunder

delivered  in person,  or if mailed by  registered  or  certified  mail (return
receipt requested)  postage prepaid,  or by a nationally  recognized  overnight
courier, or by facsimile (and promptly confirmed by registered,  certified mail
or overnight courier),  to the addresses given below or such other addresses as
may be  designated in writing by the Parties from time to time during the Term.
Any notice sent by registered, certified mail or overnight courier as aforesaid

      16.5  Assignment.  This  Agreement  may  not  be  assigned  or  otherwise
transferred  by either  Party  without the written  consent of the other Party,
provided,  however,  that either Party may,  without such consent,  assign this
Agreement, in whole or in part:

            (i)   if such Party or its Affiliates is required to, or reasonably
      believes  that  it  will  be  required to, divest either the Product or a
      competing product in order to comply  with  the  Law  or the order of any
      Governmental Authority as a result of a merger or acquisition,  provided,
      however, that, if permitted by the applicable Governmental Authority, the
      other  Party  shall  be  invited  to  submit  a  bid for the rights to be
      assigned;

            (ii)  to  any  of  its  Affiliates  (provided the  assigning  Party
      continues at all times to remain liable for all obligations of such Party
      under this Agreement without regard to such assignment);

            (iii) in  connection  with  the  transfer   or   sale   of  all  or
      substantially all of its business related to this Agreement; or

            (iv)  in accordance with Article 13.11.

      Any purported assignment in violation of this Article 16.5 shall be void.
      Any permitted assignee shall assume all obligations of its assignor under
      this Agreement.


      16.6 Non-Solicitation.  During the Term, neither Party shall, directly or
indirectly,  recruit or solicit  any  employee  of the other  Party  (including
employee's  of  Affiliates)  with whom such  Party  has come  into  contact  or
interacted  for the purposes of performing  this  Agreement,  without the prior
consent  of the other  Party,  except  pursuant  to  general  solicitation  not
targeted at such employees.

      16.7 Amendment.  The Parties hereto may amend, modify or alter any of the
provisions of this Agreement, but only by a written instrument duly executed by
both Parties hereto.

      16.8 Entire  Agreement.  This  Agreement,  along with the other  Alliance
Agreements,  contains the entire  understanding  of the Parties with respect to
the subject matter hereof.

      16.9 Waiver. The failure of a Party to enforce at any time for any period
any of the  provisions  hereof  shall  not be  construed  as a  waiver  of such
provisions  or of the rights of such  Party  thereafter  to  enforce  each such
provisions.

      16.10 No Implied Licenses.  Except as expressly and specifically provided
under this  Agreement,  the  Parties  agree that  neither  Party is granted any
implied rights to or under any of the other Party's  current or future patents,
trade secrets,  copyrights,  moral rights, trade or service marks, trade dress,
or any other intellectual property rights.


                                       82




      16.11 Independent Contractors.  The Parties agree that their relationship
established by this Agreement is that of independent contractors.  Furthermore,
the Parties agree that this  Agreement  does not, is not intended to, and shall
not be construed to,  establish a partnership or joint  venture,  and nor shall
this  Agreement  create  or  establish  an  employment,  agency  or  any  other
relationship.  Except as may be  specifically  provided  herein,  neither Party
shall have any right, power or authority,  nor shall they represent  themselves
as having any  authority to assume,  create or incur any expense,  liability or
obligation,  express or implied, on behalf of the other Party, or otherwise act
as an agent for the other Party for any purpose.

      16.12  Compliance with Law and  Severability.  It is the intention of the
Parties in  establishing  their  collaboration  pursuant to this  Agreement  to
comply with all  applicable  laws and  regulations,  including all  competition
laws.  If during the Term there are any  changes  in factual  circumstances  of
market conditions affecting the legality of this Agreement or to any applicable
law or  regulation  (including  the expiry or  withdrawal  of any  exemption or
approval)  then on written notice from one Party to the other the Parties shall
review  their  collaboration  pursuant to this  Agreement.  Such  review  shall
consider  such changes as may be required to the  structure or operation of the
collaboration,  including  the terms of this  Agreement,  which  shall  then be
negotiated  in good faith with the objective of  preserving,  so far as legally
permissible,  the terms set out herein  and, in  relation  to any  changes,  of
ensuring that the commercial  benefits and detriments arising from the required
changes are shared  equally  between the Parties.  Neither  Party shall seek to
exploit  the  requirement  to make  any  such  changes  to its  own  commercial
advantage.   In  addition,   if  any  provision  of  this   Agreement  is  held
unenforceable  by a court or  tribunal  of  competent  jurisdiction  in a final
unappealable  order  because  it is invalid  or  conflicts  with any Law of any
relevant  jurisdiction,  then  such  provision  shall  be  inoperative  in such
jurisdiction  and the remainder of this Agreement shall remain binding upon the
Parties hereto.

      16.13  Registration and Filing of the Agreement.  To the extent,  if any,
that a Party concludes in good faith that it is required under  applicable Laws
to  file  or  register  this  Agreement  or a  notification  thereof  with  any
Governmental  Authority,  including  without  limitation  the US Securities and
Exchange  Commission,  or the US Federal Trade  Commission,  in accordance with
applicable Laws, such Party may do so and shall provide the other Party to this
Agreement with a written copy of all proposed filings or registrations to allow
for a reasonably sufficient time for review and comment by the other Party. The
other Party shall  cooperate in such filing or  notification  and shall execute
all documents reasonably required in connection  therewith.  In such situation,
the Parties will request confidential  treatment of sensitive provisions of the
Agreement,  to the extent  permitted by Law. The Parties shall promptly  inform
each other as to the activities or inquiries of any such Governmental Authority
relating to this  Agreement,  and shall cooperate to respond to any request for
further information therefrom.

      16.14 Announcements.

            (i)   Coordination.    The  Parties  agree  on  the  importance  of
      coordinating   their  public  announcements   respecting   the   Alliance
      Agreements and the subject matter of such agreements.  Organon and Pfizer
      will, from time  to  time,  and at the request of the other Party discuss
      and agree on the general information  content  relating to this Agreement
      and the License Agreement which may be publicly disclosed.

            (ii)  Announcements.   The  joint  press  release   announcing  the
      signing  of  the  transactions  contemplated  by this Agreement  and  the
      Alliance  Agreements is attached hereto as Schedule  16.14  and  will  be
      promptly disseminated following signing.

            (iii) The  above-referenced  releases  may  be  Organon releases or
      joint Organon/Pfizer releases at Pfizer's option, and the  Parties  agree
      to jointly draft and agree on the content of such disclosure.  Except  as
      otherwise  provided  in  this  Article 16.14, neither Party will make any
      public announcement regarding the  fact of execution of this Agreement by
      the Parties hereof, the terms of or events related this Agreement, and/or
      the   collaboration   without   the   prior   consent   of   the


                                       83




      other.  Notwithstanding  the  foregoing,  a Party may make any disclosure
      where in a Party's  reasonable legal opinion it is required by applicable
      Law or applicable stock exchange regulation or order or other ruling of a
      competent court,  provided that prior to such disclosure,  the disclosing
      Party  shall use  reasonable  efforts to notify the other  Party prior to
      making  such  disclosure,  and  will  provide  the  other  Party  with an
      opportunity  to  review  and  comment  prior  to  release,  provided  the
      disclosing  Party shall not be required to delay such disclosures by more
      than forty-eight (48) hours to receive and discuss such comments, so long
      as the  disclosing  Party has provided to the other Party as much advance
      notice as is reasonably  practicable under the circumstances.  Each Party
      agrees that it shall reasonably  cooperate with the other with respect to
      all  disclosures  regarding  this  Agreement to the  Securities  Exchange
      Commission and any other governmental or regulatory  agencies,  including
      requests for confidential treatment of proprietary  information of either
      Party included in any such disclosure.

      16.15 HSR  Filings.  Each of Organon  and  Pfizer  shall as  promptly  as
possible  file  with the FTC and the  Antitrust  Division  of the DOJ,  any HSR
Filing  required  of it under  the HSR Act  with  respect  to the  transactions
contemplated  by this  Agreement,  and shall each use  commercially  reasonable
efforts to make such filing  within four (4) weeks of the date of  execution of
this  Agreement.  The Parties  shall  cooperate  with one another to the extent
necessary in the  preparation of any HSR Filing  required to be filed under the
HSR Act.  Each Party  shall be  responsible  for its own costs,  expenses,  and
filing fees associated with any HSR Filing.

      16.16 HSR Cooperation;  Further Assurances. Organon and Pfizer agree, and
shall cause each of their respective Affiliates,  to cooperate and to use their
respective commercially reasonable efforts to obtain any HSR Clearance required
for the consummation of the transactions  contemplated under this Agreement and
to respond to any government  requests for  information  under the HSR Act. The
Parties will consult and cooperate with one another, and consider in good faith
the  views  of one  another,  in  connection  with any  analyses,  appearances,
presentations,  memoranda,  briefs,  arguments,  opinions and proposals made or
submitted by or on behalf of either Party in connection with proceedings  under
or  relating  to the HSR Act.  For the  avoidance  of doubt,  it is agreed that
neither Party shall be obligated in any way to (i) sell,  transfer or otherwise
dispose of  (including  without  limitation  by way on any "hold  separate"  or
similar  arrangement)  any asset or product or  business,  (ii)  terminate  any
contractual  relationship,  or (iii) amend,  terminate or otherwise  modify any
licenses  or other  intellectual  property  agreements,  in order to obtain HSR
Clearance with respect to the transactions contemplated by this Agreement.

      16.17  Activities  Prior to the  Effective  Date.  The Parties  shall not
engage in any of the  activities  contemplated  by this  Agreement,  other than
seeking to obtain HSR Clearance, prior to the Effective Date.

      16.18  Headings.  The  Article  and Article  headings  contained  in this
Agreement are for  reference  purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

                                       84




      16.19  Counterparts.  This  Agreement  may be  executed  in any number of
counterparts,  each of which  shall be  deemed  an  original,  but all of which
together shall constitute one and the same document.


      IN WITNESS WHEREOF, the Parties have  executed  this  Agreement as of the
date hereof.

      anticipated Launch of the Product in such Major Market Country,  determine
      a minimum Detail Requirement for the Term in such Major Market Country.

--    The minimum  Detail  Requirement  for any Year that is not a full calendar

PFIZER AND AKZO NOBEL'S ORGANON ENTER GLOBAL COLLABORATION
FOR POTENTIAL NEW PSYCHOTROPIC TREATMENT


New York, and Arnhem, THE NETHERLANDS Oct. XX -- Pfizer Inc and Organon, the

human pharmaceutical business unit of Akzo Nobel, today announced they have

entered into a global agreement for the exclusive worldwide development and

commercialization of Organon's asenapine, a potential new psychotropic

medication for the treatment of a variety of disorders that is beginning Phase

III trials in schizophrenia and bipolar disorder.



Under terms of the agreement, which is subject to government approval, the

companies will collaborate on the clinical development and manufacturing of

asenapine, and co-promote the product in the United States, European Union,

Japan and other markets. Pfizer will make an initial payment of $100 million

and up to $270 million in milestone payments contingent upon regulatory

approvals and launch of asenapine in the U.S., Europe and Japan as well as

attainment of certain agreed-upon sales levels.  Further terms of the agreement

were not disclosed.



"Organon is excited about its partnership with Pfizer to develop and market

asenapine.  Phase II clinical trials with asenapine have shown promising

results which could assist patients in treating their psychoses," said Michael

Novinski, Organon International Board Member and President of Organon USA. "We

believe this collaboration will provide the appropriate development and

commercial resources necessary to serve the patient population who may benefit

from this treatment," said Toon Wilderbeek, Member of the Akzo Nobel Board of

Management.



"We are very pleased Organon chose Pfizer as its partner to advance the

development of asenapine, which has the potential to help patients live more

productive lives," said Karen Katen, President, Pfizer Global Pharmaceuticals.

"As with most drugs in the neuroscience category,



                                       106




psychotropic  medications work for only about 70% of individual patients so new

treatments are always  needed.  We believe  asenapine  will present  additional

options for patients and physicians in the management of psychoses, allow us to

build  upon  Pfizer's  expertise  in  this  area  and  compliment  our  current

neuroscience portfolio."


Asenapine is a 5HT2/D2 antagonist that belongs to a class of medicines known as

atypical antipsychotics.  These drugs act on both the 5HT2 and D2 receptors and

show superior tolerability and efficacy compared to older antipsychotic

medications that act mainly on D2 receptors. In early clinical studies,

asenapine was well-tolerated and showed statistically superior efficacy when

compared with placebo.



Akzo Nobel's human healthcare unit Organon, headquartered in Roseland, NJ USA,

is a renowned pharmaceutical company with a strong commitment to human health

care. The company develops and produces innovative prescription medicines for

gynecology, psychiatry, cardiovascular diseases, immunology and anesthesia.

Organon products are sold in over 100 countries, more than half of which have

an Organon subsidiary. The company currently employs approximately 13,000

people.
