to  one  or  more  committees,  and  may  authorize  further  delegation  by the
committees to senior managers of the Company,  its  Subsidiaries,  or Pharmacia;
provided,  that no  delegation  may be made of the  powers  granted to the Board
People  Committee  under Section 8.16. Any such delegation may be revoked by the
Committee at any time.

4.2.     Scope of Authority.  The Committee  shall have full power and authority
to  administer  and  interpret  this  Broad-Based  Option Plan and to adopt such
rules,   regulations,   agreements,   guidelines   and   instruments   for   the
administration of this Broad-Based  Option Plan as the Committee deems necessary

                                       7
<PAGE>

or advisable. The Committee's powers include, but are not limited to (subject to
the specific  limitations  described  herein),  the  authority to determine  the
employees to be granted Options under this Broad-Based Option Plan; to determine
the size and  applicable  terms  and  conditions  of  grants  to be made to such
employees;  to determine the time when Options will be granted; to determine the
terms and conditions of any grant, including,  without limitation,  the Exercise
Price,  any vesting  condition,  restriction  or  limitation  (which may contain
Performance  Objectives  relating to the  performance  of the  Participant,  the
Company or an Affiliate) and any acceleration of vesting or waiver of forfeiture
regarding  any grant and the Shares  relating  thereto;  to determine  whether a
resignation  was  voluntary  and  whether  a  Termination  of  Employment  was a
Termination for Cause;  and to modify,  amend or adjust the terms and conditions
of any grant made to a Participant,  at any time;  provided,  that the Committee
may not reduce the  Exercise  Price of, or cancel and regrant,  any  outstanding
Option.

4.3.     Actions and  Interpretations.  The Committee's  interpretations of this
Broad-Based  Option  Plan and of Option  Documents,  and all  actions  taken and
determinations made by the Committee concerning any matter arising under or with
respect to this Broad-Based Option Plan or any Options granted hereunder,  shall
be in its sole  discretion  and final,  binding and conclusive on all interested
parties,  including  the Company,  an  Affiliate,  stockholders  of any of those
entities,  and all former,  present and future employees thereof.  The Committee
may, with respect to all questions of  accounting,  rely  conclusively  upon any
determination made by the internal accountants of the Company.

4.4.     Board  Authority.  Any  authority  granted to the Committee may also be
exercised  by the Board.  To the extent that any  permitted  action taken by the
Board  conflicts  with action  taken by the  Committee,  the Board  action shall
control.

5.       SHARES AUTHORIZED

5.1.     Total Number. The total number of Shares that may be delivered pursuant
to Options  under this  Broad-Based  Option  Plan shall not exceed the number of
Shares that equals 1.05% of the outstanding Shares immediately after the initial
public offering of the Shares.

5.2.     Source.  The  Shares  for  which  Options  may be  granted  under  this
Broad-Based  Option Plan may be authorized but unissued  Shares not reserved for
any other  purposes  or  Shares  held in or  acquired  for the  treasury  of the
Company, or both.

5.3.     Forfeitures, Etc. If any Option is forfeited without being exercised or
any Option's  term expires,  the Shares that are, as a result,  not delivered to
the Participant  shall again be available for delivery pursuant to Options under
this Broad-Based  Option Plan. If the Exercise Price of any Option granted under
this  Broad-Based  Option Plan is satisfied by delivering  Shares to the Company
(by either actual delivery or by attestation),  only the number of Shares issued
net of the  Shares  delivered  or  attested  to shall be  deemed  delivered  for
purposes of  determining  the maximum  number of Shares  available  for delivery
under this  Broad-Based  Option  Plan.  To the  extent any Shares  covered by an
Option  are not  delivered  to a  Participant  because  such  Shares are used to
satisfy an  applicable  tax  withholding  obligation,  such Shares  shall not be

                                       8
<PAGE>

deemed to have been delivered for purposes of determining  the maximum number of
Shares available for delivery under this Broad-Based Option Plan.

6.       SHARE ADJUSTMENTS

6.1.     Adjustments.  In the event of any  change in  corporate  capitalization
such  as  a  stock  split,  any  corporate   transaction,   such  as  a  merger,
consolidation,  separation, spin-off, or other distribution of stock or property
of the Company,  any reorganization  (whether or not such  reorganization  comes
within the  definition  of  reorganization  in Section 368 of the Code),  or any
partial or complete  liquidation of the Company,  then notwithstanding any other
provision of this Broad-Based  Option Plan, the Committee or Board may make such
substitution or adjustments in the aggregate  number and kind of Shares reserved
for delivery  pursuant to Options  under this  Broad-Based  Option Plan,  in the
number and kind of Shares subject to outstanding  Options, in the Exercise Price
of outstanding Options,  and/or such other equitable substitution or adjustments
as it may  determine  to be  appropriate;  provided,  that the  number of Shares
subject to any Option shall always be a whole number.

6.2.     Adjustment Notices.  Notice of any adjustment or substitution  pursuant
to this  Section 6 (the  "Adjustment  Notice")  shall be given by the Company to
each Participant holding an affected Option;  provided,  that such adjustment or
substitution shall be effective and binding for all purposes of this Broad-Based
Option Plan whether or not an Adjustment  Notice is given. An Adjustment  Notice
may be given by making it generally  available to Participants  via a newsletter
or other written  employee  communication,  whether such  communication  is made
available on paper or electronically.  Adjustment Notices,  when given, shall be
considered to be part of the Option Documents for each affected Option.

7.       TERMS AND CONDITIONS OF STOCK OPTIONS

7.1.     Option Documents.  Each Option shall be evidenced by written materials,
including necessary terms and conditions, in such form as the Committee may from
time to time prescribe (the "Option Documents").

7.2.     Grants  of  Options.  The  Committee  may  grant  Options  to  Eligible
Employees at such times and to the extent the Committee deems advisable.

7.3.     Exercise  Price.  The  per-Share  Exercise  Price of an Option shall be
established by the Committee in connection with the grant thereof, but shall not
be less than 100% of the Fair Market Value of a Share on the Grant Date.

7.4.     Type of  Options.  Options  hereunder  shall  not be  "incentive  stock
options" within the meaning of Section 422 of the Code.

7.5.     Exercise of  Options.  An Option or portion  thereof  may be  exercised
during the period  beginning on the date when it first  becomes  exercisable  in
accordance  with its terms,  and ending upon the  expiration  of its term or, if
sooner,  when it is  forfeited as a result of a  Termination  of  Employment  or
otherwise in accordance with the terms and conditions of the Option. The term of
an Option shall expire on such date, not later than the tenth anniversary of the

                                       9
<PAGE>

Grant Date,  as set forth in the  applicable  Option  Documents.  To exercise an
Option, a Participant shall give notice to the Company or its agent,  specifying
the number of Shares  with  respect to which the Option is being  exercised  and
otherwise  complying with such procedures as the Committee may from time to time
establish (which may include procedures for oral notices of exercise).

7.6.     Payment of Exercise  Price.  For each  Option,  the  applicable  Option
Documents shall specify the form of  consideration to be paid in satisfaction of
the  Exercise  Price,  which may include  (i) cash in the form of United  States
currency or foreign currency  converted to United States dollars at the exchange
rate in  effect on the  exercise  date or  cashier's  check or  certified  check
payable to the order of the Company, (ii) Shares owned free of any restrictions,
without being subject to forfeiture, for at least six months by the Participant,
or (iii) any other method designated by the Committee.  No exercise of an Option
shall be effective before payment of the Exercise Price therefor.

7.7.     Effect of  Termination  of  Employment  on Exercise of Options.  Unless
otherwise  set  forth  in the  applicable  Option  Documents,  the  effect  of a
Participant's  Termination  of  Employment  on  any  Option  then  held  by  the
Participant to the extent it has not previously expired or been exercised, shall
be as follows:

(a)      Before  Vesting has  Commenced.  If such  Participant's  Termination of
         Employment occurs before any portion of the Option is exercisable,  the
         Participant shall forfeit such Option;

(b)      After Vesting has Commenced.  If such Termination of Employment  occurs
         after the Option has become exercisable in whole or in part:

         (i)      Voluntary  Resignation.  As  a  result  of  the  Participant's
                  voluntary resignation,  such Option shall be exercisable for a
                  period of 90 days following such Termination of Employment, to
                  the  extent  it  is   exercisable   immediately   before  such
                  Termination of Employment,  and shall then be forfeited to the
                  extent not exercised;

         (ii)     Termination  for  Cause.  In  a  Termination  for  Cause,  the
                  Participant shall forfeit such Option;

         (iii)    Retirement.  By reason of the Participant's  Retirement,  such
                  Option  shall  be  exercisable  for a  period  of  five  years
                  following such Termination of Employment,  to the extent it is
                  exercisable immediately before such Termination of Employment,
                  and shall then be forfeited to the extent not exercised; and

         (iv)     Other  Involuntary  Termination.  In the  case  of  any  other
                  Termination  of  Employment,  such Option shall be exercisable
                  for a  period  of  one  year  following  such  Termination  of
                  Employment  (including by reason of death or  Disability),  to
                  the  extent  it  is   exercisable   immediately   before  such
                  Termination of Employment,  and shall then be forfeited to the
                  extent not exercised.

                                       10
<PAGE>

(c)      Limitation.  Notwithstanding the foregoing, in no event shall an Option
         be exercisable after the expiration of its term.

7.8.     No  Obligation  to Exercise  Option.  The  granting of an Option  shall
impose no obligation upon the Participant or upon a beneficiary of a Participant
to exercise such Option.

8.       MISCELLANEOUS PROVISIONS

8.1.     Non-Transferability.  During  a  Participant's  lifetime,  his  or  her
Options  shall  be  exercisable  only by the  Participant.  No  Option  shall be
transferable  other than by will or the laws of  descent  and  distribution;  no
Option shall be subject,  in whole or in part, to attachment,  execution or levy
of any kind;  and any purported  transfer in violation  hereof shall be null and
void.  Without limiting the generality of the foregoing,  no domestic  relations
order  purporting  to authorize a transfer of an Option shall be  recognized  as
valid. The Committee may establish such procedures as it deems appropriate for a
Participant  to designate a  beneficiary  to whom any amounts  payable or Shares
deliverable  in the event of, or  following,  the  Participant's  death,  may be
provided.

8.2.     No Right to Continued Employment. Nothing contained in this Broad-Based
Option  Plan,  any Option  Documents  or any booklet or document  describing  or
referring  to this  Broad-Based  Option  Plan  shall be  deemed to confer on any
Eligible  Employee  the right to  continue  in the  employ of the  Company or an
Affiliate,  whether for the duration of a Participant's  Option vesting schedule
or  otherwise,  or affect the right of the Company or an  Affiliate to terminate
the employment of any such person for any reason.

8.3.     Governing  Law;  Construction.  This  Broad-Based  Option  Plan and any
actions taken hereunder shall be governed by, and construed in accordance  with,
the laws of the State of  Delaware,  without  regard to the  application  of the
conflicts of laws  provisions  thereof.  Titles and headings to Sections are for
purposes of reference only and shall in no way limit, define or otherwise affect
the meaning or interpretation of this Broad-Based Option Plan.

8.4.     Certain  Tax  Matters.  Notwithstanding  any  other  provision  of this
Broad-Based  Option Plan,  the Committee may make such  provisions and take such
steps as it may deem necessary or appropriate  for the  withholding of any taxes
that the  Company  is  required  by any law or  regulation  of any  governmental
authority,  whether federal, state or local, domestic or foreign, to withhold in
connection  with the grant or exercise of any Option or otherwise in  connection
with any Option,  including,  without  limitation,  the  withholding  of cash or
Shares  that would be paid or  delivered  pursuant  to such  exercise  until the
Participant  reimburses  the  Company  for the amount the Company is required to
withhold with respect to such taxes,  or canceling any portion of such Option in
an amount  sufficient  to  reimburse  the Company  for the minimum  amount it is
required to so withhold,  or selling any property  contingently  credited by the
Company for the  purpose of paying such award in order to withhold or  reimburse
the Company for the minimum  amount it is required to so withhold.  In addition,
the Committee may  establish  appropriate  procedures to ensure that it receives
prompt  notice  of any  event  that may make  available  to the  Company  or any
Affiliate any tax deduction in connection with an Option.

                                       11
<PAGE>

8.5.     Foreign Participants. In order to facilitate the granting of Options to
Eligible  Employees who are foreign nationals or who are employed outside of the
United  States of America,  the Committee may provide for such special terms and
conditions,  including  without  limitation  substitutes  for  Options,  as  the
Committee may consider  necessary or appropriate  to accommodate  differences in
local law, tax policy or custom.  The Committee may approve any  supplements to,
or amendments,  restatements or alternative  versions of this Broad-Based Option
Plan as it may  consider  necessary  or  appropriate  for the  purposes  of this
Section 8.5 without thereby affecting the terms of this Broad-Based  Option Plan
as in effect  for any other  purpose,  and the  Secretary  or other  appropriate
officer of the Company may certify any such  documents  as having been  approved
and adopted pursuant to properly  delegated  authority;  provided,  that no such
supplements,  amendments, restatements or alternative versions shall include any
provisions  that are  inconsistent  with the spirit of this  Broad-Based  Option
Plan,  as  then  in  effect.  Participants  subject  to the  laws  of a  foreign
jurisdiction may request copies of, or the right to view, any materials that are
required  to  be  provided  by  the  Company   pursuant  to  the  laws  of  such
jurisdiction.

8.6.     No Rights as a Stockholder.  No Participant  shall have any rights as a
stockholder  with  respect to any Shares  covered by an Option prior to the date
that the  Participant is recorded as the holder of such Shares on the records of
the Company or such  Shares are  delivered  to such  Participant  by  book-entry
registration  or  delivery  of a  certificate  or  certificates  therefor to the
Participant or to a custodian or escrow agent designated by the Committee (which
may include, without limitation, the Company or one or more of its employees).

8.7.     No Right to Options.  No employee or other  person shall have any claim
or right to be granted an Option  under this  Broad-Based  Option  Plan.  Having
received a grant of an Option under this Broad-Based  Option Plan shall not give
a  Participant  or other  person any right to receive any other grant of Options
under  this  Broad-Based  Option  Plan.  A  Participant  shall have no rights or
interests in any Option, except as set forth herein and in the applicable Option
Documents.

8.8.     Unfunded Plan. It is presently  intended that this  Broad-Based  Option
Plan shall be unfunded.  Except for reserving a sufficient  number of authorized
Shares  to  the  extent  required  by law  to  meet  the  requirements  of  this
Broad-Based  Option Plan,  the Company  shall not be required to  establish  any
special or separate  fund or to make any other  segregation  of assets to assure
the delivery of the Shares upon exercise of any Option granted  pursuant to this
Broad-Based Option Plan.

8.9.     Exclusion  from Pension and other Benefit Plan  Computation.  Except to
the extent otherwise  required by applicable law, by exercise of an Option,  (i)
each  Participant  shall be deemed to have  agreed  that such  Option is special
incentive  compensation  that will not be taken into account,  in any manner, as
salary,  wages,  compensation  or bonus in determining the amount of any payment
under any pension,  retirement or other employee  benefit plan of the Company or
an  Affiliate,  and (ii) each  beneficiary  of a deceased  Participant  shall be
deemed to have  agreed  that such  Option will not affect the amount of any life
insurance coverage,  if any, provided by the Company or an Affiliate on the life
of the Participant  that is payable to the beneficiary  under any life insurance
plan covering employees or directors of the Company or an Affiliate.

                                       12
<PAGE>

8.10.    Notice.  Except as otherwise  provided in this Broad-Based Option Plan,
all notices or other communications required or permitted to be given under this
Broad-Based  Option Plan to the Company  shall be in writing and shall be deemed
to have been duly given if delivered personally or mailed,  postage pre-paid, as
follows:  (i) if to  the  Company,  at its  principal  business  address  to the
attention of the Secretary; and (ii) if to any Participant,  at the last address
of the  Participant  known  to the  sender  at the  time  the  notice  or  other
communication is sent.

8.11.    Inurement of Rights and Obligations.  The rights and obligations  under
this  Broad-Based  Option  Plan and any  related  documents  shall  inure to the
benefit of, and shall be binding upon, the Company,  its successors and assigns,
and the Participants and their beneficiaries.

8.12.    Costs and Expenses of This  Broad-Based  Stock  Option Plan.  Except as
otherwise  provided  herein,  the  costs  and  expenses  of  administering  this
Broad-Based Option Plan shall be borne by the Company,  and shall not be charged
to any Option grant nor to any Participant  receiving an Option grant. Costs and
expenses  associated  with  the  exercise  of  any  Option  granted  under  this
Broad-Based Option Plan,  including,  but not limited to, commissions charged by
any agent of the Company, may be charged to the Participant.

8.13.    No Limitation on Rights of the Company

(a)      The grant of any Option  shall not in any way affect the right or power
         of the Company to make  adjustments,  reclassifications,  or changes in
         its capital or business structure or to merge,  consolidate,  dissolve,
         liquidate,  sell or transfer all or any part of its business or assets.
         Further,  this Broad-Based Option Plan shall not restrict the authority
         of the  Company,  for  proper  corporate  purposes,  to grant or assume
         Options,  other than under this  Broad-Based  Option  Plan,  to or with
         respect to any other person.

(b)      If the Committee so directs,  the Company may issue or transfer  Shares
         to an  Affiliate,  for such lawful  consideration  as the Committee may
         specify,  upon the condition or  understanding  that the Affiliate will
         transfer such Shares to a Participant  in accordance  with the terms of
         an Option  granted to such  Participant  and specified by the Committee
         pursuant to the provisions of this Broad-Based Option Plan.

8.14.    Legal Requirements

(a)      Restrictions  on Resale.  Notwithstanding  any other  provision of this
         Broad-Based Option Plan, no Participant who acquires Shares pursuant to
         this  Broad-Based  Option Plan may, during any period of time that such
         Participant  is an affiliate of the Company  (within the meaning of the
         rules and regulations of the Securities and Exchange  Commission  under
         the Securities Act of 1933 (the "1933 Act")), sell such Shares,  unless
         such offer and sale is made (i) pursuant to an  effective  registration
         statement  under the 1933 Act, which is current and includes the Shares
         to be sold,  or (ii)  pursuant  to an  appropriate  exemption  from the
         registration  requirement  of the 1933  Act,  such as that set forth in
         Rule 144 promulgated under the 1933 Act.

                                       13
<PAGE>

(b)      Registration,  Listing and Qualification of Shares. Notwithstanding any
         other  provision of this  Broad-Based  Option Plan,  if at any time the
         Committee   shall   determine   that  the   registration,   listing  or
         qualification  of the Shares  covered by an Option upon any  securities
         exchange or under any foreign, federal, state or local law or practice,
         or the consent or  approval of any  governmental  regulatory  body,  is
         necessary or desirable as a condition  of, or in connection  with,  the
         granting  of  such  Option  or  the   purchase  or  receipt  of  Shares
         thereunder,  no such  Option  may be  exercised,  and no Shares  may be
         delivered or received  pursuant to such  Option,  unless and until such
         registration,  listing,  qualification,  consent or approval shall have
         been effected or obtained  free of any condition not  acceptable to the
         Committee.  Any  Participant  exercising an Option or receiving  Shares
         thereunder shall make such  representations  and agreements and furnish
         such information as the Committee may request to assure compliance with
         the foregoing or any other applicable legal  requirements.  The Company
         shall  not  be  required  to  issue  or  deliver  any   certificate  or
         certificates for Shares under this Broad-Based Option Plan prior to the
         Committee's  determination  that all  related  requirements  have  been
         fulfilled.  The Company  shall in no event be obligated to register any
         securities  pursuant to the 1933 Act or applicable state or foreign law
         or to take any other action in order to cause the issuance and delivery
         of such  certificates  to  comply  with any  such  law,  regulation  or
         requirement.

8.15.    Fractional  Shares.  The  Company  shall not be  required  to issue any
fractional  Shares pursuant to this  Broad-Based  Option Plan. The Committee may
provide for the elimination of fractions or for the settlement thereof in cash.

8.16.    Amendment or Termination

(a)      The Board People Committee may, from time to time, amend or modify this
         Broad-Based Option Plan or any outstanding Options, including,  without
         limitation, to authorize the Committee to make Options payable in other
         securities or other forms of property of a kind to be determined by the
         Committee,  and such other  amendments as may be necessary or desirable
         to implement such Options, or terminate this Broad-Based Option Plan or
         any provision thereof; provided, that no amendments or modifications to
         this Broad-Based  Option Plan shall,  without the prior approval of the
         stockholders normally entitled to vote for the election of directors of
         the Company,  permit the Company to decrease the Exercise  Price of any
         outstanding Option; and provided,  further,  that amendments to Section
         5.1 shall require the approval of the Board.

(b)      No amendment to or termination of this  Broad-Based  Option Plan or any
         provision   hereof,   and  no  amendment  to  or  cancellation  of  any
         outstanding  Option shall,  without the written consent of the affected
         Participant, adversely affect any outstanding Option.

(c)      Notwithstanding the above provisions,  the Board People Committee shall
         have authority to amend outstanding Options and this Broad-Based Option
         Plan to take into account  changes in law and tax and accounting  rules

                                       14
<PAGE>

         as well as other  developments,  and to grant  Options that qualify for
         beneficial treatment under such rules, without stockholder approval and
         without the consent of affected Participants.

8.17.    Change of Control

(a)      The provisions of this Section 8.17(a) shall apply  notwithstanding any
         provision of this  Broad-Based  Plan other than Sections 8.4, 8.14, and
         8.17(b),  unless  the  Committee  determines  otherwise  at the time of
         grant.  Upon the  occurrence  of a  Monsanto  Change  of  Control,  all
         then-outstanding Options, whether or not previously exercisable,  shall
         vest and be exercisable.  In addition,  upon the occurrence of a Second
         Trigger  after  a  Pharmacia  Change  of  Control  with  respect  to  a
         Participant,  all then-outstanding  Options,  whether or not previously
         exercisable, shall vest and be exercisable.

(b)      With respect to Options held by a Participant who is also a Participant
         in the  Monsanto  Company  Excess  Parachute  Tax  Indemnity  Plan (the
         "Indemnity  Plan") or any comparable or successor plan at the time of a
         Change of Control,  the vesting  provided for in Section  8.17(a) shall
         not occur as a result of that Change of Control, to the extent that the
         provisions  of Section 4(b) of the  Indemnity  Plan (or any  comparable
         provision  of such  comparable  or  successor  plan)  require that such
