     Agreement,  **** of any  such  fees to  Calgene  at the  time  the fees are
     collected.
         4.02  Monsanto  Royalties  Due. (a) Except as provided for in Paragraph
     10.13, in further  consideration  for the licenses to Calgene Patent Rights
     granted hereunder, Monsanto shall pay to Calgene a royalty equal to **** of
     the Net Profits for each  Licensed  Product  calculated  for such  Licensed
     Product sold by Monsanto and Monsanto Affiliates;  provided,  however, that
     (i) Monsanto shall use reasonable  efforts to obtain  information as to Net
     Profits for each Licensed Product sold by Monsanto Affiliates,  but Calgene
     recognizes that, for some Monsanto Affiliates, such information will not be
     available to Monsanto;  and (ii) where such  information  is not available,
     Calgene  and  Monsanto  shall  negotiate  in good  faith on an  alternative
     methodology  to  determine  the  compensation  due to  Calgene  on such Net
     Profits;
     (b) Except as provided  for in Paragraph  10.13,  for Net Sales of Licensed
     Products  by  sublicensees  of Monsanto  or a Monsanto  Affiliate,  further
     consideration  for the licenses to Calgene Patent Rights granted  hereunder
     shall be paid to  Calgene  based  on the  greater  of:  (i) **** of any net
     license fees,  royalties or other income received by Monsanto or a Monsanto
     Affiliate  resulting from Third Party sales of Commodity  Oilseed Products,
     Commodity  Canola Products and Commodity High Stearate Canola Products that
     utilize  Calgene Patent Rights under  sublicenses  granted by Monsanto or a
     Monsanto  Affiliate.  In no event  will the  definition  of Net  Profits of
     Licensed Products include items in this subparagraph; (ii) either: (A) ****
     of net sales of such  sublicensees,  provided that Monsanto's direct grower
     license  revenues  (or other  revenues  not  collected  from  seed  company
     licensees)  are at least **** of such net sales;  or (B) **** of Monsanto's
     direct grower  license  revenues (or other revenues not collected from seed
     company  licensees)  in the event that such  revenues are less than **** of
     such net sales.  In no event will the definition of Net Profits of Licensed
     Products include items in this subparagraph;
     (c) Earned royalties shall accrue to Calgene,  subject to the provisions of
     Paragraph  4.06, when Licensed  Products are invoiced,  or if not invoiced,
     when delivered to a Third Party;
     (d) If a Licensed  Product  and several  other items are sold and  invoiced
     together,  the  discount on such sale shall be computed as a fraction,  the

     Product  and items as a bundle and the  denominator  of which is the sum of
     the then-current list prices of Monsanto, the

     Monsanto Affiliate or their respective sublicensee, as the case may be, for
     such  Licensed  Product and items.  Upon the  invoicing or delivery of such
     bundle,  the gross invoiced sales price for such Licensed  Product shall be
     deemed to be: (i) the  then-current  list price of  Monsanto,  the Monsanto
     Affiliate  or their  respective  sublicensee,  as the case may be, for such
     Licensed Product; multiplied by (ii) the discount, as computed above.
         4.03 Calgene  Royalties Due. In consideration for paying to Calgene the
     amount described in Paragraph 4.01(b) above, the licenses of Paragraph 3.02
     and sharing Technical Information as provided in Paragraph 3.04(c), Calgene
     shall  pay to  Monsanto  ****  of the  positive  Net  Profits  of the  Oils
     Division.   If  the  Oils  Division   acquires  new  business   operations,
     facilities,  technologies  and/or license rights after the Effective  Date,
     then Monsanto shall have the option either:  (i) to contribute  **** of the
     amounts  paid by the Oils  Division  for such  acquisition;  or (ii) to not
     contribute  any such  amount,  in which case  Monsanto's  **** share of the
     positive Net Profits of the Oils Division shall be reduced accordingly.
         4.04 First  Commercial Sale. (a) Monsanto shall promptly advise Calgene
     in  writing  of the first  commercial  sale of  Licensed  Products  in each
     country.  (b) The earned  royalties  described in  Paragraph  4.02 shall be
     deemed to be payable for  Licensed  Products  invoiced or delivered in each
     country of the world so long as the Calgene  Patent  Rights  covering  such
     Licensed  Products  have not expired or have not been  declared  invalid in
     such country.
         4.05 Royalty  Reports (a)  Beginning  December  31, 1996,  and annually
     thereafter, Monsanto shall submit to Calgene a progress report covering the
     activities  related to the development and testing of all Licensed Products
     and the  obtaining of the  governmental  approvals  necessary for marketing
     them.  These progress reports shall be made for each Licensed Product until
     the first  commercial  sale of that Licensed  Product  occurs in the United
     States.(b)  After the first  commercial sale of a Licensed Product anywhere
     in the world,  Monsanto will make annual  royalty  reports to Calgene on or
     before  February 28th of each year. Each such royalty report will cover the
     most recently  completed  calendar year and will show:  (i) the gross sales
     and Net Profits for each Licensed Product;  (ii) the number of each type of
     Licensed  Product  sold;  (iii) the  royalties,  in U.S.  dollars,  payable
     hereunder with respect to such sales; (iv) the method used to calculate the
     royalty;  and (v) the  exchange  rates  used.(c)  For  each  calendar  year
     (commencing  with calendar year ▇▇▇▇),  ▇▇▇▇▇▇▇ will make annual reports to
     Monsanto on or before  February 28th  following  each such year.  Each such
     report will cover the most recently  completed calendar year and will show:
     (i) the gross sales and Net Profits of
                                        -12-
     the Oils Division; (ii) the number of each type of product sold by the Oils
     Division;  (iii) the payments,  in U.S.  dollars,  payable  hereunder  with
     respect to such sales; (iv) the method used to calculate the payments;  and
     (v) the  exchange  rates  used.  (d) If no sales have been made  during any
     calendar year, a statement to this effect shall be required.
         4.06 Manner of Payment (a)  Concurrent  with the  submission of reports
     pursuant to Paragraph 4.05, Monsanto shall make the earned royalty payments
     then due and Calgene shall make the payments then due pursuant to Paragraph
     4.03.  All  payments  hereunder  shall be made by deposit of United  States
     Dollars in the  requisite  amount to such bank account in the United States
     as the  receiving  Party may from time to time  designate  by notice to the
     other. As to the royalty payments  payable to Calgene,  amounts shall first
     be calculated in the currency in which the sale of a Licensed  Product took
     place and then converted to U.S. Dollars at the closing buying rate for the
     last  business day of the  calendar  year for which such payment is due, as
     set by Chase Manhattan Bank of New York.  Payments shall be without set off
     and free  and  clear of any  taxes,  duties,  fees or  charges  other  than
     withholding taxes, if any.(b) If at any time legal restrictions prevent the
     prompt  remittance of part or all royalties by Monsanto with respect to any
     country where a Licensed Product is sold, Monsanto shall have the right and
     option to make such  payments  by  depositing  the amount  thereof in local
     currency  to  Calgene's  account  in a bank  or  other  depository  in such
     country. If, after one year, these legal restrictions still exist, Monsanto
     shall pay the  royalties  owed to  Calgene in  interest  from its source of
     funds in the U.S.
         4.07 No  Non-Monetary  Consideration  for Sales.  Neither  Party  shall
     accept  or  solicit  any  non-monetary  consideration  in the  sale  of any
     Licensed  Product  or  products,  other than as would be  reflected  in the
     calculation  of Net Sales.  The use by a Party of  commercially  reasonable
     amounts of Licensed Products or products for promotional sampling shall not
     violate this prohibition.
         4.08 Records  Retention.  (a) Monsanto  agrees to keep, and shall cause
     Monsanto  Affiliates and sublicensees to keep, records showing all Licensed
     Products  manufactured,  used and/or  sold and  licensing  of all  Licensed
     Products in sufficient  detail to permit Calgene to confirm the accuracy of
     Monsanto's earned royalty  calculations.  Calgene agrees to keep, and shall
     cause Calgene  Affiliates and  sublicensees  to keep,  records  showing all
     products manufactured,  used and/or sold by the Oils Division and licensing
     of all  products  by the Oils  Division  in  sufficient  detail  to  permit
     Monsanto to confirm the accuracy of  Calgene's  payment  calculations.  All
     determinations  related to royalties and payments due under this  Agreement
     shall be
                                        -13-

     made in accordance  with  generally  accepted  accounting  principles as is
     normal industry  practice.  (b) At the request of a Party,  the other Party
     shall permit an independent,  certified public accountant  appointed by the
     requesting Party and reasonably  acceptable to such other Party to examine,
     upon  reasonable  notice,  and at reasonably  times,  records solely to the
     extent  necessary to verify the other  Party's  calculations.  Such records
     shall be kept and examination  thereof shall be limited to a period of time
     no more than two (2) calendar  years.(c) Prompt adjustment shall be made by
     the  Parties  to reflect  the  results  of any such  audit.  The audit of a
     Party's records shall be at the auditing Party's expense provided that if a
     net aggregate  discrepancy  in the audited  Party's favor of more than five
     percent  (5%) is  found,  then the  audited  Party  shall be  obligated  to
     reimburse  the  auditing  Party for the cost of the audit.  (d) The Parties
     agree that any dispute arising from an audit of a Party's records and which
     can not be  resolved  by the  Parties  shall be  subject  to the  following
     arbitration  procedure;  (i) the Parties shall first have their  respective
     CEO's meet to review the issues raised by the audit,  provided that, in the
     event that  Monsanto  has  acquired a majority of the  outstanding  Calgene
     stock, an independent  director of the Calgene board shall stand in for the
     Calgene  CEO in such  audit  review;  and  (ii)  should  the  procedure  in
     4.08(d)(i)  fail to resolve  the  dispute,  the  parties  shall  appoint an
     outside  arbitrator which is acceptable to both parties,  with authority to
     resolve the dispute.
         4.09 Late Payment. Notwithstanding any other remedy available to either
     Party under the provisions of this Agreement,  if any sum of money owned to
     a Party  hereunder  is not paid when due,  the  unpaid  amount  shall  bear
     interest  at the  lesser  of:  (a) a rate of 10% per  annum or (b)  maximum
     interest rate under  applicable  law,  calculated from the date payment was
     due until actually received by such Party.

     obligations and agrees, prior to any disclosure of Confidential Information
     to such individuals or entities,  to make them bound (by written  agreement
     or otherwise) by obligations of confidentiality and limited use of the same
     stringency as those contained in this Agreement.
         6.05  Confidential  Status of  Agreement.  The terms of this  Agreement
     including the royalty rate shall be deemed to be  Confidential  Information

     the full  understanding  of the Parties,  and  supersedes any and all prior
     agreements  as they  may  relate  to  licenses  granted  herein,  with  the
     exception  that for sales of Glyphosate  tolerant  products by Monsanto the
     agreements between the Parties regarding  Glyphosate  tolerant genes, dated
     December 20, 1994,  (Settlement  Agreement ) and  transgenic  technologies,
     dated April 22, 1993,  (Transgenic  Plants  Agreement ) shall be treated in

     unenforceability  shall not affect any other  provisions  hereof,  but this
     Agreement shall be construed as if such invalid or illegal or unenforceable
     provisions had never been contained herein.

     counterparts, each of which shall be an original with the same effect as if

     "direct  product",  as used above, is defined to mean the immediate product
     (including  process  and  services)  produced  directly  by the  use of the
     technical data.
         10.11 Force  Majeure (a) Except for  payments of money,  neither of the
     Parties  shall be liable  for any  default or delay in  performance  of any

     cause  upon which said Party is  relying.  Telephone,  telegram,  telex and
     telecopier  notices  shall be  confirmed  in writing by the  sending  Party

         10.12  Negation of Agency.  It is agreed and  understood by the Parties
     hereto  that  each of  Monsanto  and  Calgene,  in its  performance  of its
     obligations and  responsibilities  under this Agreement,  is an independent
     contractor and that nothing herein  contained  shall be deemed to create an
     agency,  partnership,  joint  venture  or like  relationships  between  the
     Parties.  The manner in which each of Monsanto  and  Calgene  carry out its
     performance under this Agreement is within each of Monsanto's and Calgene's
     sole discretion and control.
         10.13 Existing Agreements. Subject to the provisions of this paragraph,
     to the extent that rights  provided under existing  agreements  between the
     Parties are not in conflict with this  Agreement,  this Agreement shall not
     terminate  rights  under  such  existing  agreements.(a)  For any  Licensed
     Product,  other than sales of Glyphosate tolerant canola by Monsanto,  if a
     Party would have an  obligation  to pay  royalties  to the other Party both
     under this Agreement and under a prior agreement  between the parties,  the
     payment  due  the  other  Party  shall  be   determined   only  under  this
     Agreement.(b)  Royalties and fees for a Glyphosate tolerant canola Licensed
     Product  produced by Monsanto  shall be  determined as  follows:(i)  if all
     necessary   Calgene  Patent  Rights  utilized  by  Monsanto  in  conferring
     glyphosate  tolerance to such Licensed Product is covered by the Settlement
     Agreement and/or the Transgenic Plants Agreement,  the royalties payable to
     Calgene shall be determined  pursuant to such Settlement  Agreement  and/or
     Transgenic  Plants  Agreement,  as the case may  be;(ii)  if such  Licensed
     Product  incorporates  a Calgene  Patent  Right for any purpose  other than
     conferring  glyphosate  tolerance to such  Licensed  Product the  royalties
     payable to  Calgene  shall be  determined  pursuant  to this  Agreement.For
     example:  if Monsanto sells  glyphosate  tolerant  genetically  transformed
     canola with a non-  genetically  engineered oil  composition  the royalties
     would be those called for in the Transgenic Plants  Agreement;  if Monsanto
     sells Glyphosate  tolerant canola which also produces an oil which has been
     modified  using  Calgene  Technology  licensed  under this  agreement,  the
     royalty  payable to Calgene for such  Licensed  Product shall be determined
     pursuant to this Agreement.
                                        -22-
