                                      -10-
   11
MONSANTO.  Notwithstanding the above provisions of this Subsection 4.01(a),
MONSANTO shall not be obligated to negotiate access to such other consideration
(i.e., other than cash or cash equivalent) for DEKALB, except as provided in
Subsection 3.11.
                 (b)      In further consideration for the license rights
granted by DEKALB hereunder, MONSANTO shall pay as a royalty to DEKALB an       
amount equal to the [***] or (ii) [***] of the payment established for
Subsection 4.02(a), times the Net Units of Licensed DEKALB Corn Products or
Licensed MONSANTO Corn Products sold by DEKALB and its Affiliates and
International Associates until the obligation under Subsection 4.02(a) of
DEKALB to pay royalties to MONSANTO expires.
                 (c)      If DEKALB subsequently grants a license under the
Licensed DEKALB Patent Rights to a third party having terms which considered as
a whole are more favorable to the licensee than the terms considered as a whole
granted to MONSANTO as set forth in Subsection 4.01(a), then DEKALB shall
advise MONSANTO as to such more favorable terms.  MONSANTO shall, at its
election, be entitled upon notice to DEKALB to have this Agreement amended to
substitute such third party terms for the terms of this Agreement as of the
date upon which such license containing the more favorable terms shall have
become effective; provided, however, that MONSANTO also agrees to have the
Agreement amended to contain any additional obligations that are recited in
such license containing the more favorable terms.
                 (d)      In the event DEKALB shall at any time while this
Agreement is in effect be compelled by applicable law to issue licenses under
the Licensed DEKALB Patent Rights in the Licensed Field to any other person
with royalty terms more favorable than those granted to MONSANTO hereunder,
DEKALB shall inform MONSANTO of the order compelling any such licenses and
shall offer the royalties only with respect to the country or countries wherein
such compulsory licenses have been ordered so that the new royalty terms shall
be no less favorable to MONSANTO than those granted to any third party under
any such compulsory license.
                 (e)      Nothing in this Subsection 4.01 shall entitle
MONSANTO to any retroactive adjustment, reduction in royalty, or other relief
from any of the provisions of this Agreement merely because DEKALB shall
commence proceedings against a third party who has infringed the Licensed
DEKALB Patent Rights, which proceedings shall be resolved by the third party
becoming licensed under the Licensed DEKALB Patent Rights, so long as such
subsequent license agreement shall, at least prospectively, impose upon such
third party terms as to royalty no more favorable than the royalty terms
imposed upon MONSANTO under this Agreement as set forth in Subsection 4.01(a).

         4.02             ROYALTIES PAYABLE BY DEKALB:
                 (a)      In partial consideration for the license rights
granted by MONSANTO hereunder, DEKALB shall pay as a royalty to
MONSANTO an amount equal to [***] the Net Units of Licensed DEKALB Corn
Products or Licensed MONSANTO Corn Products sold by DEKALB and its Affiliates
and International Associates, [***]





                                      -11-
   12
                        (b) In partial consideration for the license rights
granted by MONSANTO hereunder, until the obligation of DEKALB to pay royalties  
to MONSANTO expires, DEKALB shall pay to MONSANTO [***] of any cash or
cash-equivalent consideration or other consideration received by DEKALB, other
than consideration received for sales by DEKALB and its Affiliates and
International Associates covered under Subsection 4.02(a), on any sale of
Licensed MONSANTO Corn Products or Licensed DEKALB Corn Products in the
Licensed Field in the Territory by persons licensed by DEKALB under the
Licensed DEKALB Patent Rights pursuant to the terms of this Agreement [***]. 
To the extent DEKALB intends to negotiate a sublicense that contemplates such
other consideration that is not cash or a cash equivalent, DEKALB shall [***]. 
MONSANTO shall have fifteen (15) business days to consider whether to accept
enjoyment of the benefit of such other consideration, or to reject such
enjoyment and accept instead a cash value equivalent thereto.  If MONSANTO does
not provide notice of acceptance of enjoyment of the benefit of such other
consideration to DEKALB within the fifteen (15) day period, MONSANTO shall be
deemed to have accepted the cash value equivalent thereto.  To the extent there
exists any such other consideration, including but not limited to a
cross-license, involved in the sublicense, the monetary equivalent thereof
shall be agreed by the parties for the purpose of this Subsection 4.02(b).  If
despite good faith negotiations, the parties cannot reach agreement on the
monetary equivalent, then determination of such equivalent shall be submitted
to arbitration pursuant to the provisions of Subsection 10.15, if requested by
either party.  Examples of such other consideration include technical data or a
sublicense under any license obtained by DEKALB.  Notwithstanding the above
provisions of this Subsection 4.02(b), DEKALB shall not be obligated to
negotiate access to such other consideration (i.e., other than cash or cash
equivalent) for MONSANTO, except as provided in Subsection 3.11. 
                        (c)      If MONSANTO subsequently grants a license 
under the Licensed MONSANTO Patent Rights to a third party having terms which
considered as a whole are more favorable to the licensee than the terms
considered as a whole granted to DEKALB as set forth in Subsection 4.02(a),
then MONSANTO shall advise DEKALB as to such more favorable terms.  DEKALB
shall, at its election, be entitled upon notice to MONSANTO to have this





                                      -12-
   13



Agreement amended to substitute such third party terms for the terms of this
Agreement as of the date upon which such license containing the more favorable
terms shall have become effective; provided, however, that DEKALB also agrees
to have the Agreement amended to contain any additional obligations that are
recited in such license containing the more favorable terms.
                 (d)      In the event MONSANTO shall at any time while this
Agreement is in effect be compelled by applicable law to issue licenses under
the Licensed MONSANTO Patent Rights in the Licensed Field to any other company
with royalty terms more favorable than those granted to DEKALB hereunder,
MONSANTO shall inform DEKALB of the order compelling any such licenses and
shall offer the royalties only with respect to the country or countries wherein
such compulsory licenses have been ordered so that the new royalty terms shall
be no less favorable to DEKALB than those granted to any third party under any
such compulsory license.
                 (e)      Nothing in this Subsection 4.02 shall entitle DEKALB
to any retroactive adjustment, reduction in royalty, or other relief from any
of the provisions of this Agreement merely because MONSANTO shall commence
proceedings against a third party who has infringed the Licensed MONSANTO
Patent Rights, which proceedings shall be resolved by the third party becoming
licensed under the Licensed MONSANTO Patent Rights, so long as such subsequent
license agreement shall, at least prospectively, impose upon such third party
terms as to royalty no more favorable than the royalty terms imposed upon
DEKALB under this Agreement as set forth in Subsection 4.02(a).

         4.03             FIRST COMMERCIAL SALE IN A COUNTRY:
                 (a)      The parties  shall promptly advise one another  in

                 (b)      At the time such first commercial sale  is reported

DEKALB Corn Products sold outside the United States or on sublicenses granted

                 (b)      Each payment to MONSANTO hereunder shall be sent to:
                 (i)      MONSANTO's account by wire transfer:
                                   [***]

MONSANTO may subsequently designate from time to time by notice to DEKALB.
                 (c)      Each payment to DEKALB hereunder shall be sent to:
                          (i)     DEKALB's account by wire transfer:

all consideration received on licenses granted by DEKALB in the Licensed Field

an independent accountant appointed by the requesting party and reasonably
acceptable to the other party to examine, not more often than once during any
Fiscal Year and under appropriate confidentiality provisions, upon reasonable
notice of at least ten (10) days and at reasonable times and in a manner that
does not interfere unreasonably with the other party's business, such 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 three (3) Fiscal Years immediately preceding the request for
examination.
                 (b)      The audit of the other party's records shall be at

                 (b)      MONSANTO shall have the exclusive right (but not the
obligation) to institute and conduct legal action against third-party
infringers of the Licensed MONSANTO Patent Rights, and to enter into settlement

appropriate by MONSANTO.  MONSANTO shall receive the full benefits of any
action it takes pursuant to this Subsection 6.02; provided however, that once
any attorney's fees and other reasonable costs incurred in conducting such
legal action have been deducted from any recovery obtained from enforcement of
Licensed MONSANTO Patent Rights which arise, MONSANTO shall pay to DEKALB its

                 (c)      If the activities of the third party infringing the

business of DEKALB or any of its Affiliates or International Associates or
sublicensees and at the end of One Hundred and Eighty (180) days from the
receipt of notice from DEKALB of such infringement, the third party is both
unlicensed under the Licensed MONSANTO Patent Rights and is engaging in
activities which are an infringement of the Licensed MONSANTO Patent Rights,
and MONSANTO has not brought a suit, action or other proceeding for
infringement against such third party, then DEKALB and all of its Affiliates
and International Associates and sublicensees shall be excused from  making the
payments otherwise due hereunder with respect to revenues derived from sales of
Licensed DEKALB Corn Products or Licensed MONSANTO Corn Products in a country
in which the competitive infringing activity occurs.  Such excuse from payment
shall arise only as to sales by DEKALB and its Affiliates, International
Associates and sub-licensees of the affected Licensed DEKALB Corn Products or
Licensed MONSANTO Corn Products in the country in which the infringing products
are sold and shall continue only for so long as the infringing products
continue to be infringing and to so compete with such Licensed DEKALB Corn
Products or Licensed MONSANTO Corn Products unchallenged by an infringement
suit, action or other proceeding brought by MONSANTO.  If the infringing
activities of more than one third party result in such a material adverse
effect, then MONSANTO will fulfill its obligation under this Subsection through
litigation with only one such third party at a time.
                 (d)      DEKALB shall have the exclusive right (but not the
obligation) to institute and conduct legal action against third-party
infringers of the Licensed DEKALB Patent Rights, and to enter into settlement
agreements as a way of responding to any infringements as may be deemed
appropriate by DEKALB.  DEKALB shall receive the full benefits of any action it
takes pursuant to this Subsection 6.02; provided however, that once any
attorney's fees and other reasonable costs incurred in conducting such legal
action have been deducted from any recovery obtained from enforcement of
Licensed DEKALB Patent Rights which arise, DEKALB shall pay





                                      -18-
   19



to MONSANTO its pro rata portion of such recovery, calculated in accordance
with the terms of this Agreement as they apply to amounts received pursuant to
the applicable Licensed DEKALB Patent Rights.
                 (e)      If the activities of the third party infringing the
Licensed DEKALB Patent Rights result in a material adverse effect on the
business of MONSANTO's sublicensees and at the end of One Hundred and Eighty
(180) days from the receipt of notice from MONSANTO of such infringement, the
third party is both unlicensed under the Licensed DEKALB Patent Rights and is
engaging in activities which are an infringement of the Licensed DEKALB Patent
Rights, and DEKALB has not brought a suit, action or other proceeding for
infringement against such third party, then MONSANTO and all of its
sublicensees shall be excused from making the payments otherwise due hereunder
with respect to revenues derived from sublicenses of Licensed MONSANTO Corn
Products or Licensed DEKALB Corn Products in the country in which the
competitive infringing activity occurs.  Such excuse from payment shall arise
only as to sales by MONSANTO's Affiliates, International Associates and
sublicensees of the affected Licensed MONSANTO Corn Products or Licensed DEKALB
Corn Products in the country in which the infringing products are sold and
shall continue only for so long as the infringing products continue to be
infringing and to so compete with such Licensed MONSANTO Corn Products or
Licensed DEKALB Corn Products unchallenged by an infringement suit, action or
other proceeding brought by DEKALB.  If the infringing activities of more than
one third party result in such a material adverse effect, then DEKALB will
fulfill its obligation under this Subsection through litigation with only one
such third party at a time.
                 (f)      DEKALB shall not have the right (by operation of law
or otherwise) to enforce any Licensed MONSANTO Patent Right licensed hereunder
against any alleged infringer.  MONSANTO shall not have the right (by operation
of law or otherwise) to enforce any Licensed DEKALB Patent Right licensed

                          SECTION 9 - CONFIDENTIALITY

         9.01             CONFIDENTIAL INFORMATION:  The parties have
previously disclosed and it is anticipated that it will be necessary, in
connection with their obligations under this Agreement, for DEKALB and MONSANTO
to disclose to each other Confidential Information.  The Confidential
Information shall include, but shall not be limited to, information disclosed
in writing or other tangible form, including samples of materials.

         9.02             CONFIDENTIALITY AND LIMITED USE:
                 (a)      With respect to all Confidential Information, both
DEKALB and MONSANTO agree as follows, it being understood that "recipient"
indicates the party receiving the confidential, proprietary information from
the other "disclosing" party. Confidential Information disclosed to the
recipient shall remain the property of the disclosing party and shall be
maintained in confidence by the recipient with the same care and diligence as
the recipient maintains its own Confidential Information.  Confidential
Information shall not be disclosed to third parties by the recipient and,
further, shall not be used except for purposes contemplated in this Agreement.
All confidentiality and limited use obligations with respect to the
Confidential





                                      -24-
   25



Information shall terminate ten (10) years after the termination date of this
Agreement.
                 (b)      Notwithstanding any provision to the contrary, a
party may disclose the Confidential Information of the other party: (i) in
connection with an order of a court or other government body or as otherwise
required by or in compliance with law or regulations; provided that the party
required to disclose provides the other party with notice and takes reasonable
measures to obtain confidential treatment thereof; (ii) in confidence to
recipient's attorneys, accountants, banks and financial sources and its
advisors; or (iii) in confidence, in connection with the sale of substantially
all the business assets to which this Agreement relates, so long as, in each
case, the entity to which disclosure is made is bound to confidentiality on
terms consistent with those set forth herein.
                 (c)      Notwithstanding any provision to the contrary, a
party seeking to make a disclosure to an entity not bound to confidentiality on
terms consistent with those set forth herein shall first provide to the other
party a copy of the material proposed to be disclosed and shall obtain the
consent of the other party before making the disclosure, which consent shall
not be unreasonably withheld .

         9.03             EXCEPTIONS:  The obligations of confidentiality and
limited use shall not apply to any of the Confidential Information which:
                 (a)      is publicly available by publication or other
documented means or later becomes likewise publicly available through no act or
fault of recipient; or
                 (b)      is already known to recipient before receipt from the
disclosing party, as demonstrated by recipient's written records; or
                 (c)      is made known to recipient by a third party who did
not obtain it directly or indirectly from the disclosing party and who does not
obligate recipient to hold it in confidence; or
                 (d)      is independently developed by the recipient as
evidenced by credible written research records of recipient's employees or
agents who did not have access to the disclosing party's Confidential
Information.  Specific information should not be deemed to be within any of
these exclusions merely because it is embraced by more general information
falling within these exclusions.

         9.04             DISCLOSURES TO PERSONNEL:  Recipient agrees to advise
those of its officers, directors, employees, associates, agents, consultants,
Affiliates, and International Associates who become aware of the Confidential
Information, of these confidentiality and limited use obligations and agrees,
prior to any disclosure of Confidential Information to such individuals or
entities, to make them bound by obligations of confidentiality and limited use
of the same stringency as those contained in this Agreement.
  
         9.05             RETURN OF CONFIDENTIAL INFORMATION:  Upon termination
of this 





                                      -25-
   26



Agreement, originals and copies of Confidential Information in written or other
tangible form will be returned to the disclosing party by recipient or
destroyed by recipient.  One copy of each document may be retained in the
custody of the recipient's legal counsel solely to provide a record of what
disclosures were made.

         9.06             CONFIDENTIAL STATUS OF AGREEMENT:  The terms of this
Agreement shall be deemed to be Confidential Information and shall be dealt
with according to the confidentiality requirements of this Section 9.  Neither
party will make public disclosures concerning specific terms of this Agreement
without obtaining the prior written consent of the other party, which consent
shall not be unreasonably withheld and except as may be necessary, in the
opinion of counsel of the party making such disclosure, to comply with the
requirements of any stock exchange or over-the-counter market on which the
shares of such party may be listed or of any law, governmental regulation or
order.  If a party determines that such a disclosure is necessary, it shall
promptly notify the other party so that the other party can obtain confidential
treatment of its Confidential Information.
