         conceived by Employee, and copyrights to all software, writings or
         other materials prepared by Employee, in each case solely or with
         others, while employed by the Company, during or after working hours,
         which are related to the actual or anticipated business of the Company,
         belong exclusively to the Company. Employee shall make full and prompt
         written disclosure to the Company of the above. At the request and

         employment, Employee shall execute a written assignment of and shall
         assist in acquiring and maintaining patent or other proprietary
         information protection of the Company's rights to such inventions,
         ideas, improvements, designs or copyrights.

14.      For three years after employment, Employee will not, in any way or
         capacity, solicit any officer, director, employee or other individual:

         A.     to leave employment or any position with the Company,

         B.     to compete with the business of the Company, or

         C.     to violate the terms of any agreement with the Company.

15.      For 24 months following termination of Employee's employment with
         Company for any reason whatsoever, Employee will not, in any way or
         capacity, participate in or have any employment, consultant, financial,
         management or other interest in any business enterprise anywhere that
         engages in or plans to engage in (either at the time of Employee's
         termination and/or during the 24-month period following such
         termination) significant or substantial competition with any business
         conducted by the Company involving the producing, distributing or
         marketing of hybrid or specialized agricultural seeds or conducting or
         administering any research activities relating to hybrid or specialized
         agricultural seeds.

16.      During the period set forth in paragraph 15, the Company shall (except
         in the case of Employee's termination on account of death or inability
         to perform Duties due to disability) pay Employee one-twelfth of
         Employee's base salary and one-twelfth of Employee's target annual
         performance bonus (both at the rate in effect on Employee's termination
         date) for every one month during the period set forth in paragraph 15.
         The Company shall not, however, be obligated to make such payments
         during any period of time that Employee is in breach of paragraph 15 of
         this Agreement.

17.      Payments by the Company to Employee pursuant to paragraph 16 shall be 
         in addition to the Company's severance policy under change of control.
         Payments pursuant to paragraph 16 shall not, however, be in lieu of any
         compensation due Employee for Company's breach of this Agreement (e.g.,
         the Company's obligation to make salary 


                                       2
   3


         and bonus payments in the event of the Company's termination of
         Employee without cause during the term of this Agreement or any annual
         extension thereof). The Company agrees to be liable for, reimburse
         Employee for, and advance Employee amounts for taxes required to be
         paid by Employee under Section 4999 of the Internal Revenue Code of
         1986, as amended, due to compensation, fringe benefits and other
         remuneration provided by the Company to the Employee ("Remuneration"),
         and any interest and penalties with respect to such taxes (such taxes,
         interest and penalties, "Excise Tax") and to provide the Employee with
         an additional payment (a "Gross-Up Payment") in an amount such that
         after payment by the Employee of all taxes (including any interest or
         penalty imposed with respect to such taxes), including without
         limitation any income taxes (and any interest and penalties imposed
         with respect thereto) and Excise Tax imposed upon the Gross-Up Payment,
         the Employee retains an amount of the Gross-Up Payment equal to the
         Excise Tax imposed upon the Remuneration. The Company agrees to pay all
         such amounts pursuant to, and all other amounts with respect thereto
         provided by and pursuant to, the terms of the Company's policies and
         procedures in effect at the time of the change of ownership or
         effective control of the Company pursuant to which such Excise Tax may
         become payable.

18.      Employee agrees that (a) both the duration and geographic scope of
         paragraph 15 are necessary to reasonably and adequately protect the
         Company's businesses, and (b) the compensation provided in paragraph 16
         will adequately compensate Employee during transition to new employment
         or other status.

19.      Employee will not begin employment with another employer without first
         giving at least thirty days notice to the Company. Prior to accepting
         any new employment, Employee shall inform his new employer of the
         existence of this Agreement and provide a copy hereof to such new
         employer.

20.      Except as otherwise provided in this Agreement, Employee's rights under
         any employee benefit plan shall not be affected by this Agreement.

21.      Employee has received a copy of both the DEKALB Antitrust Compliance
         Policy and the DEKALB Business Conduct Standards. Employee will adhere
         to the policies and principles contained therein, and will require all
         employees reporting to Employee to adhere to those policies and
         principles.

22.      The Company shall have the right, at its own expense and for its own
         benefit, to take out life insurance on Employee in such amount or
         amounts as it shall see fit, and Employee agrees to cooperate with the
         Company in obtaining such insurance.

23.      The Beneficiary Designation form attached hereto as Exhibit B is a part
         of this Agreement. In the event of Employee's death when no beneficiary
         designation is in effect, the Company shall make payment of any amounts
         to which Employee was entitled to Employee's personal representative,
         heirs, devisees or legatees. Employee may change Exhibit B at any time,
         by providing an amended version to the Personnel Department.

24.      Without limiting the rights of the Company to pursue all other legal 
         and equitable rights 


                                       3
   4


         available to the Company, it is agreed that: (a) the Duties performed
         by Employee are of a special, unique, unusual and extraordinary
         character which give them a peculiar value, and the loss of such
         performance cannot be reasonably and adequately compensated in damages
         in an action at law, and (b) remedies other than injunctive relief
         cannot fully compensate the Company for violation of Paragraphs 10
         through 19, of this Agreement; accordingly, the Company shall be
         entitled to injunctive relief to prevent violations of such paragraphs
         or continuing violations thereof. All of Employee's covenants in and
         obligations under Paragraphs 10 through 19, this Agreement shall
         continue in effect notwithstanding termination of Employee's employment
         under any circumstances whatsoever.

25.      If in any proceeding a term, geographic or other restriction, covenant
         or promise contained herein is found to be unreasonable, unlawful or
         otherwise invalid and for that reason unenforceable, then such term,
         geographic or other restriction, covenant or promise shall
         automatically be deemed modified to the extent necessary to make it
         enforceable.

26.      This Agreement shall be binding upon the Company, its successors and
         assigns and upon Employee, Employee's heirs, executors and
         administrators. This Agreement may be assigned by the Company or
         transferred by operation of law. Employee agrees that if the Company is
         sold or Employee is transferred to a subsidiary or affiliate, or from
         one subsidiary or affiliate to another, all terms and conditions of
         this Agreement shall remain in force as if it initially had been made
         with that purchaser, subsidiary or affiliate.

27.      Notices contemplated by this Agreement shall be effective when
         delivered in writing to the Company at 3100 Sycamore Road, DeKalb, IL
         60115, ATTN: General Counsel or to Employee at 1101 Iroquois Avenue,
         #2223, Naperville, IL 60563.

28.      This Agreement, including Exhibits A, B, C and D as they may be amended
         from time to time, all confidentiality agreements and all invention
         assignment agreements signed by Employee during any employment with the
         Company, contain the entire agreement between the parties hereto with
         respect to the transactions contemplated herein; together they
         supersede all prior negotiations and other agreements, both oral and
         written, between the parties and they cannot be modified except by an
         instrument in writing signed by both parties.
