and directly related to the Company Products within three (3) years after the

employment. Employee shall not disclose any such Improvement to any person,
except the Company and shall use all reasonable efforts to provide the Company
written disclosure of such Improvements. Each such Improvement shall be the sole
and exclusive property of and is hereby assigned to the Company. Employee agrees
that, at the request of the Company, Employee will execute such applications,
statements, assignments or other documents, furnish such information and data
and take all such other action (including without limitation the giving of
testimony) as the Company may from time to time reasonably request in order to
obtain for the Company a registration or patent in the United States or any

Company's actual or demonstrably anticipated research or development, or (b) the
Improvement results from any work performed by Employee for the Company.

        10.2 Employee agrees to execute and be bound by the terms of the

                            Company and which are not remedied by Employee

                     cure such breach within thirty (30) days after receiving
                     written notice from Employee describing such breach and
                     specifically referring to this Section 11.1(b).

        11.2 EMPLOYEE'S RESPONSIBILITIES UPON TERMINATION

        Following any notice of termination, Employee shall fully cooperate with
the Company in all matters relating to the winding up of his pending work on
behalf of the Company and to the orderly transfer of any such pending work to
other employees of the Company as may be designated by the Company.

        11.3 EXCESS PARACHUTE LIMITATION

        If either the Company or the Employee receives confirmation from the
Company's independent tax counsel or its certified public accounting firm, or
such other accounting firm retained as independent certified public accountants
for the Company (the "Tax Advisor"), that any payment by the Company to the
Employee under this Agreement or otherwise would be considered to be an "excess
parachute payment" within the meaning of Section 280G of the Internal Revenue
Code of 1986, as amended, or any successor statute then in effect (the "Code"),
then the aggregate payments by the Company pursuant to this Agreement shall be
reduced to the highest amount that may be paid to the Employee by the Company
under this Agreement without having any portion of any amount payable to the
Employee by the Company

                                      -6-
<PAGE>   7

or a related entity under this Agreement or otherwise treated as such an "excess
parachute payment", and, if permitted by applicable law and without adverse tax
consequence, such reduction shall be made to the last payment due hereunder. Any
payments made by the Company to the Employee under this Agreement which are
later confirmed by the Tax Advisor to be "excess parachute payments" shall be
considered by all parties to have been a loan by the Company to the Employee,
which loan shall be repaid by the Employee upon demand together with interest
calculated at the lowest interest rate authorized for such loans under the Code
without a requirement that further interest be imputed.

        11.4 NOTICE

        The term "Notice of Termination" shall mean at least 20 working days'
written notice of termination of Employee's employment, during which period
Employee's employment and performance of services will continue; provided,
however, that the Company may, upon notice to Employee and without reducing
Employee's compensation during such period, excuse Employee from any or all of
his or her duties during such period. The effective date of the termination of
Employee's employment hereunder shall be the date on which such 20-day period
expires.

12.     TERMINATION PAYMENTS

        In the event of termination of the employment of Employee, all
compensation and benefits set forth in this Agreement shall terminate except as
specifically provided in this Section 12:

        12.1 TERMINATION BY THE COMPANY

        If the Company terminates Employee's employment prior to the end of the
term of this Agreement, Employee shall be entitled to receive (a) termination
payments equal to the amounts payable under Section 7 of the Agreement, and (b)
any unpaid annual base salary and any accrued vacation and deferred compensation
(together with accrued interest or earnings thereon, if any) payable under the
deferral plan, which has accrued for services already performed as of the date
termination of Employee's employment becomes effective.

        12.2 TERMINATION BY EMPLOYEE

        In the case of the termination of Employee's employment by Employee,
Employee shall not be entitled to any payments hereunder, other than those set
forth in clause (b) of Section 12.1 hereof.

        12.3 EXPIRATION OF TERM

Section 12.1 hereof.

        12.4 TERMINATION IN CONNECTION WITH A CHANGE IN CONTROL

        Concurrent with the commencement of Employee's employment hereunder,
Employee and the Company shall enter into a Change of Control Agreement, a copy
of which is attached hereto as Exhibit A. Notwithstanding Sections 12.1 and 12.2
of this Agreement and in full substitution therefor, if Employee's employment
terminates under circumstances described in the Change of Control Agreement,
Employee's rights upon termination will be governed by terms of the Change of
Control Agreement and his right to termination payments under this Employment
Agreement shall cease.

        12.5 PAYMENT SCHEDULE

        All payments under this Section 12 shall be made to Employee at the same
interval as payments of salary were made to Employee immediately prior to
termination.

13.     INTEGRATION

        This Agreement constitutes the entire agreement between Employee and the
Company relating in any way to the employment of Employee by the Company, and
supersedes all prior discussions, understandings and agreements between them
with respect thereto.

14.     INVALID PROVISION

        The invalidity or unenforceability of any particular provision of this
Agreement shall not affect any other provision hereof, and the Agreement shall
be construed in all other respect as if such invalid or unenforceable provisions
were omitted. However, if any court should determine that the duration or any
other feature of any restriction contained in Section 7 of this Agreement is
unenforceable, it is the intention of the parties that the provisions of such
Section as set forth herein shall not thereby be terminated, but shall be deemed
amended to the extent required to render them valid and enforceable.

retroactively or prospectively) only with the written consent of the parties.

19.     ASSIGNMENT

        This Agreement is personal to Employee and shall not be assignable by
Employee. Subject to the provisions of Section 11.3 hereof, the Company may
assign its rights hereunder to (a) any corporation resulting from any merger,
consolidation or other reorganization to which the Company is a party or (b) any
corporation, partnership, association or other person to which the Company may
transfer all or substantially all of the assets and business of the Company
existing at such time. All of the terms and provisions of this Agreement shall

20.     CONSENTS AND WAIVERS

obligations of such party hereunder. Failure on the part of any party to
complain of any act or failure to act of any other party or to declare the other

consent or approval in any one instance by or on behalf of the Company shall not
be construed to waive or limit the need for such consent or approval in any
other subsequent instance.

21.     CONSTRUCTION

        This Agreement has been submitted to the scrutiny of, and has been
negotiated by, all parties hereto and their counsel, and shall be given a fair
and reasonable interpretation in accordance with the terms hereof, without
consideration or weight being given to its having been drafted by any party
hereto or its counsel.

22.     HEADINGS

only as a matter of convenience and for reference, and in no way define, limit,
extend or describe the scope of this Agreement or the intent of any provisions
hereof.

23.     REMEDIES IN EQUITY

        The rights and remedies of the parties hereunder shall not be mutually
exclusive, i.e., the exercise of one or more of the provisions hereof shall not
preclude the exercise of any other provisions hereof. The parties confirm that
damages at law will be an inadequate remedy for a breach or threatened breach of
this Agreement and agree that their respective rights and obligations hereunder
shall be enforceable by specific performance, injunction or other equitable
remedy as well as at law or otherwise.

24.     ARBITRATION

        Any controversies or claims arising out of or relating to this Agreement

Association then in effect (the AAA Rules), conducted by one arbitrator either
mutually agreed upon by the company and the employee or chosen in accordance

may be authorized and adopted from time to time in the future by the Company.

the Company grants to its senior executives.

        Employee agrees that during the Employment Period and for a period of

with the Company, without the prior written consent of the Company, either
directly or indirectly operate, control, advise, be engaged by, perform any
consulting services for, invest in (other than less than one percent of the
outstanding stock in a publicly held corporation which is listed on the NASDAQ
national market or traded over-the-counter or on a recognized securities
exchange) or otherwise become associated in any capacity with, any business,
company, partnership, organization, proprietorship, or other entity who or which
manufactures products or traits which use organisms or other byproducts or which
is developing products or traits, to (i) treat soil or foliar diseases of plants
or (ii) enhance growth or insect tolerance of plants (the "Company Products") in
competition with the Company in those geographical areas in which the Company
conducts or has conducted such business, or intends to conduct business,
consistent with the Company's current, written business plans, during Employee's
employment, provided, however, nothing herein shall preclude Employee from
accepting a position following the Employment Period to teach or conduct
research solely for academic purposes at a university or similar institution of
higher learning. If employee is released from strict compliance with his
non-compete obligations in order to return to an "academic" position, he will be
required to forego working on any project that is either funded by or for the
benefit of a for-profit company. Employee shall be paid his base annual salary,
including reimbursement for company standard health care benefits for Employee
and his dependents, during any required noncompetition period up to a maximum of
eighteen (18) months, provided he complies with the obligations set forth in
Sections 7, 8, 9 and 10 herein.

8.      NONDISCLOSURE

        Employee agrees at all times to hold as secret and confidential (unless
disclosure is required by the Company or would be in furtherance of Employee's
employment with the Company or is required pursuant to court order, subpoena in
a governmental proceeding, arbitration or pursuant to other process or
requirement of law) any and all knowledge, information, developments,
manufacturing and trade secrets, know-how and confidences of the Company or its
business of which he has knowledge during the Employment Period, to the extent
such matters have not previously been made public, are not thereafter made
public, or do not otherwise become available to Employee from a third party not,
to Employee's best knowledge, bound by any confidentiality agreement with the
Company ("Confidential Information"). The phrase "made public" as used in this
Agreement shall apply to matters within the domain of (a) the general public or
(b) the Company's industry. Employee agrees not to use such knowledge for his
own benefit or for the benefit of others or, except as provided above, disclose
any of such Confidential Information without the prior written consent of the
Company, which consent shall make express reference to this Agreement.

9.      NONINTERFERENCE

        Employee agrees that during the Employment Period and for a period of
eighteen (18) months thereafter, he will not, except in furtherance of his
employment with the Company or as a part of his duties as an officer of the
Company, without the prior written consent of the Company, directly or
indirectly solicit, induce or attempt to solicit or induce any employee, agent
or other representative or associate of the Company to terminate its
relationship with the Company or in any way interfere with such a relationship
or a relationship between the Company and any of its suppliers or distributors.

10.     DISCLOSURE OF PROPRIETARY INTELLECTUAL PROPERTY

        10.1 Employee agrees that he will promptly disclose to the Company any
and all improvements, discoveries, ideas, developments or inventions composing
proprietary intellectual property which may be material to the operations and
business of the Company (the "Improvements") which Improvements are made or
conceived by Employee, acting alone or in conjunction with others, (a) during
the Employment Period, or (b) to the extent the Improvements are specifically
and directly related to the Company Products within three (3) years after the
Employment Period, if such Improvement results from or was suggested by such
employment. Employee shall not disclose any such Improvement to any person,
except the Company and shall use all reasonable efforts to provide the Company
written disclosure of such Improvements. Each such Improvement shall be the sole
and exclusive property of and is hereby assigned to the Company. Employee agrees
that, at the request of the Company, Employee will execute such applications,
statements, assignments or other documents, furnish such information and data
and take all such other action (including without limitation the giving of
testimony) as the Company may from time to time reasonably request in order to
obtain for the Company a registration or patent in the United States or any
foreign country covering or pertaining to any such Improvement. The Company and
Employee hereby acknowledge and agree that the obligations set forth in this
Section 10 do not apply to an Improvement for which no equipment, supplies,
facility, copyright, patent or patent application, registration, information, or
other intellectual property or trade secret information of the Company was used
and which was developed entirely on Employee's own time, unless (a) the
Improvement relates (i) directly to the business of the Company, or (ii) to the
Company's actual or demonstrably anticipated research or development, or (b) the
Improvement results from any work performed by Employee for the Company.

        10.2 Employee agrees to execute and be bound by the terms of the
Company's Employee Confidentiality and Disclosure Agreement.

11.     TERMINATION OF EMPLOYMENT

        11.1   EMPLOYMENT STATUS

        The Employee and the Company acknowledge that the employment of the
Employee by the Company is "at will" and may be terminated by either the
Employee or the Company at any time.

        11.2   EVENTS OF TERMINATION

               (a)    Notwithstanding anything to the contrary contained herein,
                      this Agreement shall terminate immediately and, except for
                      the obligations of Employee set forth in Sections 8, 9, 10
                      and 11.3 hereof and the payment by the Company of all
                      salary, expenses or benefits which may be earned but
                      unpaid or unreimbursed (as the case may be) as of the date
                      of termination which obligations shall survive such
                      termination, all rights and obligations of the Company and
                      Employee hereunder shall be completely null and void upon
                      the earliest to occur of the following:

                      (i)    the death or total disability of Employee;

                      (ii)   the termination of Employee's employment by the
                             Company during the term of this Agreement; or

                      (iii)  the voluntary termination by Employee of his
                             employment with the Company during the term of this
                             Agreement pursuant to Section 11.2(b) hereof.

               (b)    Employee may terminate this Agreement in the event the
                      Company fails or refuses to perform, or otherwise breaches
                      (e.g., the departure of the CEO with or without cause),
                      the provisions of this Agreement and the Company fails to
                      cure such breach within thirty (30) days after receiving
                      written notice from Employee describing such breach and
                      specifically referring to this Section 11.2(b).

        11.3   EMPLOYEE'S RESPONSIBILITIES UPON TERMINATION

        Following any notice of termination, Employee shall fully cooperate with
the Company in all matters relating to the winding up of his pending work on
behalf of

                                      -5-
<PAGE>   6

the Company and to the orderly transfer of any such pending work to other
employees of the Company as may be designated by the Company.

        11.4   EXCESS PARACHUTE LIMITATION

        If either the Company or the Employee receives confirmation from the
Company's independent tax counsel or its certified public accounting firm, or
such other accounting firm retained as independent certified public accountants
for the Company (the "Tax Advisor"), that any payment by the Company to the
Employee under this Agreement or otherwise would be considered to be an "excess
parachute payment" within the meaning of Section 280G of the Internal Revenue
Code of 1986, as amended, or any successor statute then in effect (the "Code"),
then the aggregate payments by the Company pursuant to this Agreement shall be
reduced to the highest amount that may be paid to the Employee by the Company
under this Agreement without having any portion of any amount payable to the
Employee by the Company or a related entity under this Agreement or otherwise
treated as such an "excess parachute payment", and, if permitted by applicable
law and without adverse tax consequence, such reduction shall be made to the
last payment due hereunder. Any payments made by the Company to the Employee
under this Agreement which are later confirmed by the Tax Advisor to be "excess
parachute payments" shall be considered by all parties to have been a loan by
the Company to the Employee, which loan shall be repaid by the Employee upon
demand together with interest calculated at the lowest interest rate authorized
for such loans under the Code without a requirement that further interest be
imputed.

        11.5   DEFINITION OF TOTAL DISABILITY

        The term "total disability" as used herein shall mean Employee's
inability to perform the duties set forth in Section 2 hereof for a period or
periods aggregating 120 calendar days in any 12-month period as a result of
physical or mental illness, loss of legal capacity or any other cause beyond
Employee's control, unless Employee is granted a leave of absence by the Board
of Directors of the Company. Employee and the Company hereby acknowledge that
Employee's ability to perform the duties specified in Section 2 hereof is of the
essence of this Agreement. Termination hereunder shall be deemed to be effective
(a) at the end of the calendar month in which Employee's death occurs or (b)
immediately upon a determination by the Board of Directors of the Company of
Employee's total disability, as defined herein.

                                      -6-
<PAGE>   7

        11.6   NOTICE

        The term "Notice of Termination" shall mean at least 20 working days'
written notice of termination of Employee's employment, during which period
Employee's employment and performance of services will continue; provided,
however, that the Company may, upon notice to Employee and without reducing
Employee's compensation during such period, excuse Employee from any or all of
his or her duties during such period. The effective date of the termination of
Employee's employment hereunder shall be the date on which such 20-day period
expires.

12.     TERMINATION PAYMENTS

        In the event of termination of the employment of Employee, all
compensation and benefits set forth in this Agreement shall terminate except as
specifically provided in this Section 12:

        12.1   TERMINATION BY THE COMPANY

        If the Company terminates Employee's employment prior to the end of the
term of this Agreement, Employee shall be entitled to receive (a) termination
payments equal to the amounts payable under Section 7 of the Agreement, (b) any
unpaid annual base salary and any accrued vacation and deferred compensation
(together with accrued interest or earnings thereon, if any) payable under the
deferral plan, which has accrued for services already performed as of the date
termination of Employee's employment becomes effective and (c) the acceleration
of all unvested stock options.

        12.2   TERMINATION BY EMPLOYEE

        In the case of the termination of Employee's employment by Employee,
Employee shall not be entitled to any payments hereunder, other than those set
forth in clause (b) of Section 12.1 hereof.

        12.3   EXPIRATION OF TERM

        In the case of a termination of Employee's employment as a result of the
expiration of the term of this Agreement, Employee shall not be entitled to
receive any payments hereunder, other than those set forth in clause (b) of
Section 12.1 hereof.

        12.4   TERMINATION IN CONNECTION WITH A CHANGE IN CONTROL

        Concurrent with the commencement of Employee's employment hereunder,
Employee and the Company shall enter into a Change of Control Agreement, a copy

                                      -7-
<PAGE>   8

of which is attached hereto as Exhibit A. Notwithstanding Sections 12.1 and 12.2
of this Agreement and in full substitution therefor, if Employee's employment
terminates under circumstances described in the Change of Control Agreement,
Employee's rights upon termination will be governed by terms of the Change of
Control Agreement and his right to termination payments under this Employment
Agreement shall cease.

        12.5   PAYMENT SCHEDULE

        All payments under this Section 12 shall be made to Employee at the same
interval as payments of salary were made to Employee immediately prior to
termination.

13.     NOTICE AND CURE OF BREACH

        Whenever a breach of this Agreement by either party is relied upon as
justification for any action taken by the other party pursuant to any provision
of this Agreement, before such action is taken, the party asserting the breach
of this Agreement shall give the other party at least twenty (20) working days'
prior written notice of the existence and the nature of such breach before
taking further action hereunder and shall give the party purportedly in breach
of this Agreement the opportunity to correct such breach during the 20-day
period.

supersedes all prior discussions, understandings and agreements between them
with respect thereto.

16.     INVALID PROVISION

        The invalidity or unenforceability of any particular provision of this
Agreement shall not affect any other provision hereof, and the Agreement shall
be construed in all other respect as if such invalid or unenforceable provisions
were omitted. However, if any court should determine that the duration or any
other feature of any restriction contained in Section 7 of this Agreement is
unenforceable, it is the intention of the parties that the provisions of such
Section as set forth herein shall not thereby be terminated, but shall be deemed
amended to the extent required to render them valid and enforceable.

17.     ATTORNEYS' FEES

        In the event of a dispute arising out of the interpretation or
enforcement of this Agreement, the prevailing party shall be entitled to recover

any action arising out of this Agreement or the parties' performance hereunder

20.     AMENDMENTS

may be waived (either generally or in a particular instance and either
retroactively or prospectively) only with the written consent of the parties.

21.     ASSIGNMENT

        This Agreement is personal to Employee and shall not be assignable by
Employee. The Company may assign its rights hereunder to (a) any corporation
resulting from any merger, consolidation or other reorganization to which the
Company is a party or (b) any corporation, partnership, association or other
person to which the Company may transfer all or substantially all of the assets
and business of the Company existing at such time. All of the terms and
provisions of this Agreement shall be binding upon and shall inure to the
benefit of and be enforceable by the parties hereto and their respective
successors and permitted assigns.

22.     CONSENTS AND WAIVERS

        No consent or waiver, express or implied, by any party hereto to or of
any breach or default by any other party in the performance by the others of
their obligations hereunder shall be valid unless in writing, and no such
consent or waiver shall be deemed or construed to be a consent or waiver to or
of any other breach or default in the performance by such other party of the
same or any other obligations of such party hereunder. Failure on the part of
any party to complain of any act or failure to act of any other party or to
declare the other parties in default, irrespective of how long such failure
continues, shall not constitute a waiver by such party of its rights hereunder.
The granting of any consent or approval in any one instance by or on behalf of
the Company shall not be construed to waive or limit the need for such consent
or approval in any other subsequent instance.

extend or describe the scope of this Agreement or the intent of any provisions
hereof.

25.     REMEDIES IN EQUITY

        The rights and remedies of the parties hereunder shall not be mutually
exclusive, i.e., the exercise of one or more of the provisions hereof shall not
preclude the exercise of any other provisions hereof. The parties confirm that
damages at law will be an inadequate remedy for a breach or threatened breach of
this Agreement and agree that their respective rights and obligations hereunder
shall be enforceable by specific performance, injunction or other equitable
remedy as well as at law or otherwise.
