                 (b)      If there is no Most Favored Licensee having a license

negotiation.  The licensing party may establish such an estimate by obtaining
agreements from third parties to license or in any manner, including good faith
negotiations between the parties. The party seeking the license may pay
consideration and agree to such other terms as in the good faith estimate or
otherwise established, including by good faith negotiations.
                 (c)      If despite good faith negotiations, the parties can

The parties further agree as follows:
                          (i)     The parties may mutually agree, on a
case-by-case basis, that one of them may receive [***] of the Value, with the
other party taking the remainder.
                          (ii)    If the Collaborative Effort also is an

                 (b)      The parties agree that the Lead Collaborator shall

the case of crops that are not both a DEKALB Crop and a MONSANTO Crop, a party

Collaborative Effort.  The party whose Crops are not involved shall provide the
other party the opportunity to propose remuneration under this Subsection
5.02(c)





                                      -12-
   13
[***] before providing a license to a third party.  The party whose Crops are

                        (d)      Subsection 5.02(a) and (b) notwithstanding, in
the case of crops that are both a DEKALB Crop and a MONSANTO Crop,
either party may offer to the other party terms regarding remuneration for     
preferred states regarding a Right resulting from a Collaborative Effort.  The
other party may accept any proposed remuneration on which the parties agree,

Subsection 5.02(b) and shared in accordance with Subsection 5.02(a).

         5.03             MOST FAVORED LICENSEE STATUS; MONSANTO LICENSES:
                 (a)      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 Subsections 5.01 and 5.02, then
MONSANTO shall promptly advise DEKALB as to such more favorable terms.  DEKALB
shall, at its election, be entitled upon notice to MONSANTO to have its license
amended to substitute such third party terms for the terms of its license as of
the date upon which such license containing the more favorable terms shall have
become effective; provided, however, that (i) DEKALB also agrees to have
DEKALB's license amended to contain any additional obligations that are recited
in such license containing the more favorable terms and (ii) to the extent
there exists any non-cash consideration, including but not limited to a cross
license, involved in the more favorable license, the monetary equivalent
thereof shall be agreed by the parties for the purpose of





                                      -13-

evaluating the terms of the license.  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 12.15, if requested by either party.
                 (b)      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 Field to any other person with terms
considered as a whole more favorable than those granted to DEKALB hereunder,
MONSANTO shall inform DEKALB of the order compelling any such licenses and
shall offer the terms only with respect to the country or countries wherein
such compulsory licenses have been ordered so that the new terms shall be no
less favorable to DEKALB than those granted to any third party under any such
compulsory license.
                 (c)      Nothing in this Subsection 5.03 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 considered as a whole no more favorable than the terms considered as a
whole imposed upon DEKALB under this Agreement as set forth in Subsections 5.01
and 5.02.

                 (a)      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 Subsections 5.01 and 5.02, then DEKALB
shall promptly advise MONSANTO as to such more favorable terms.  MONSANTO
shall, at its election, be entitled upon notice to DEKALB to have that license
amended to substitute such third party terms for the terms of its license as of
the date upon which such license containing the more favorable terms shall have
become effective; provided, however, that (i) MONSANTO also agrees to have
MONSANTO's license amended to contain any additional obligations that are
recited in such license containing the more favorable terms and (ii) to the
extent there exists any non-cash consideration, including but not limited to a
cross-license, involved in the more favorable license, the monetary equivalent
thereof shall be agreed by the parties for the purpose of evaluating the terms
of the license.  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
12.15, if requested by either





                                      -14-
   15



party.
                 (b)      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 Field to any other person with terms
considered as a whole more favorable than those granted to MONSANTO hereunder,
DEKALB shall inform MONSANTO of the order compelling any such licenses and
shall offer the terms only with respect to the country or countries wherein
such compulsory licenses have been ordered so that the new terms shall be no
less favorable to MONSANTO than those granted to any third party under any such
compulsory license.
                 (c)      Nothing in this Subsection 5.04 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 MONSANTO Patent Rights, so long as such
subsequent license agreement shall, at least prospectively, impose upon such
third party terms considered as a whole no more favorable than the terms
considered as a whole imposed upon MONSANTO under this Agreement as set forth
in Subsection 5.01 and 5.02.

least sixty (60) days written notice to the other party should the other party
commit a material breach of its obligations or be in material default under any

                          SECTION 11 - CONFIDENTIALITY

         11.01   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 not limited to, information





                                      -24-
   25



disclosed in writing or other tangible form, including samples of materials.

         11.02   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 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.

         11.03   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





                                      -25-
   26



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.

         11.04   DISCLOSURES TO PERSONNEL:  Recipient agrees to advise those of
its officers, directors, employees, associates, agents, consultants,
Affiliates, Business Associates, 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.

         11.05   RETURN OF CONFIDENTIAL INFORMATION:  Upon termination of this
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.

         11.06   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 11.  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.

if DEKALB's share had been [***] it shall be [***] and MONSANTO's share shall
be [***] 
                          (ii)    to the extent necessary to adjust the revenue
shares, Subsection 5.02 shall automatically be amended as follows:
                                  (a)      the Value received with regard to a
