                          (ii)     for each Agricultural Product that is not a
seed product, upon the designation for development through the standard AgrEvo
development decision approval process (or, if not subject to the standard AgrEvo
development decision approval process, the substantially equivalent process for
an Affiliate of AgrEvo or a licensee of AgrEvo or an Affiliate, as the case may
be); provided, however, that AgrEvo shall not be required to pay a Milestone Fee
with respect to such Agricultural Product if such designation for development
relates to an improved compound that has the same use and is based on the same
Genetic Target as a compound for which a Milestone Fee has been paid previously
pursuant to this Section 7.7(a)(ii); provided further, that in the event that
AgrEvo has previously made at least [ * * * ] Milestone Fee payments to Gene
Logic with respect to Agricultural Products identified through their effect on
the same Genetic Target, the Milestone Fee shall be [ * * * ] for each
additional Agricultural Product that is identified through its effect on such
Genetic Target.

                 (b)      Notwithstanding the provisions of Section 7.7(a), in
the event that AgrEvo is obligated to make milestone payments to Third Parties
upon the designation for development with respect to an Agricultural Product in
an aggregate amount of at least [ * * * ], the Milestone Fee shall be [ * * * ].

        7.8      CURRENCY OF PAYMENT. All payments to be made under this
Agreement shall be made in United States dollars in the United States to a bank
account designated by Gene Logic; the bank account initially designated by Gene
Logic is set forth in Schedule 7.9. All amounts payable by AgrEvo to Gene Logic
pursuant to this Section 7 shall be non-refundable and non-creditable against
any other payments due under this Agreement. Royalties shall be determined in
the currency of the country in which they are earned and then converted to its
equivalent in United States currency. The buying rates involved for the currency
of the United States into which the currencies involved are being exchanged
shall be the one quoted by The Wall Street Journal (or, if not available, by
Citibank (or its successor) in New York, New York) at the close of business on
the last business day of the calendar year in which the royalties were earned to
determine any such conversion.

        7.9      PAYMENT AND REPORTING. Royalties due to Gene Logic pursuant to
Section 7.6 will be paid by AgrEvo to Gene Logic on or before March 31 of the
calendar year immediately following the year in which such royalties were
earned. AgrEvo will provide to Gene Logic with each annual royalty payment a
statement of Net Sales and/or Licensee Revenues for each Agricultural Product
sold during the applicable calendar year on a country-by-country basis,
including a calculation of the royalty amount payable for each Agricultural
Product and supporting data sufficient for Gene Logic to confirm the accuracy of
such calculations. Such reports shall constitute Confidential Information under
this Agreement. If provision is made in law or regulation for withholding, such
tax shall be deducted from the payments to be made by AgrEvo and shall be paid
by AgrEvo to the proper taxing authority and a receipt of payment of the tax
secured and promptly delivered to Gene Logic. Each party agrees to assist the
other party in claiming exemption from or credit for such deductions or
withholdings under any double taxation or similar agreement or treaty from time
to time in force. All amounts payable to Gene Logic pursuant to this Agreement
shall be made by wire transfer pursuant to the instructions set forth on
Schedule 7.9.

        7.10     RECORDS AND AUDITS. During the Agreement Term and for a period
of five years thereafter, AgrEvo shall keep complete and accurate records
pertaining to the development and sale or other disposition of Agricultural
Products in sufficient detail to permit Gene Logic to confirm the accuracy of
all payments due hereunder. Gene Logic shall have the right to cause an
independent, certified public accountant reasonably acceptable to AgrEvo to
audit such records to confirm Net Sales and Licensee Revenues and royalty and
other payments for the preceding year. Such audits may be exercised during
normal business hours once a year upon at least 30 working days' prior written
notice to AgrEvo. Gene Logic shall bear the full cost of such audit unless such
audit discloses a variance of more than 10% from the amount of the Net Sales or
royalties or other payments due under this Agreement. In such case, AgrEvo shall
bear the full cost of such audit and Gene Logic shall have the right to audit
all prior years not previously audited.

8.      SECURITY AND CONFIDENTIALITY.

disclosed to employees, agents, consultants or sublicensees of the Receiving
Party or its Affiliates but only to the extent required to accomplish the
purposes of this Agreement and only if the Receiving Party obtains prior
agreement from its employees, agents, consultants and sublicensees to whom
disclosure is to be made to hold in confidence and not make use of such
information for any purpose other than those permitted by this Agreement. Each
party will use at least the same standard of care as it uses to protect
proprietary or confidential information of its own to ensure that such
employees, agents, consultants and sublicensees do not disclose or make any
unauthorized use of the Confidential Information. Notwithstanding any other
provision of this Agreement, each party may disclose the terms of this Agreement
to lenders, investment bankers and other financial institutions of its choice
solely for purposes of financing the business operations of such party either
(i) upon the written consent of the other party or (ii) if the disclosing party
obtains a signed confidentiality agreement with such financial institution with

        12.1     MUTUAL INDEMNIFICATION. Each party agrees to defend, indemnify
and hold harmless the other party and its Affiliates, employees, agents,
officers, directors and permitted from and against any judgments, settlements,
damages, awards, costs (including attorneys' fees and costs) and other expenses
arising out of any claims, actions or other proceedings by a Third Party
(collectively a "Claim") arising out of or resulting from the development,
manufacture, use, promotion, marketing, handling, storage or sale of any
Agricultural Product, except to the extent that (i) such Claim arises out of or
results from the negligence or misconduct of the party claiming a right of
indemnification under this Section 12.1, (ii) such Claim arises out of or
results from infringement of the patent rights of any Third Party by the Gene
Logic Background Technology if Gene Logic is the party claiming a right of

        12.2     CHANGE OF CONTROL.

                 (a)      In the event of a Change in Control, as that term is
defined in Section 12.2(b), of Gene Logic during the Research Term, then Gene
Logic shall notify AgrEvo of any such Change of Control as soon as the Change in
Control may be publicly announced. In the event that Gene Logic is acquired by a
Third Party in any manner described in Section 12.2(b) that in the good faith
determination of the Board of Directors of AgrEvo is hostile to the interests of
AgrEvo in the Commercial Field, then AgrEvo shall have the right to give notice
to Gene Logic within 90 days after receipt of Gene Logic's notification that
AgrEvo elects (i) to continue the Agreement, or (ii) Alternative E - to
terminate the Research Term and have Gene Logic grant to AgrEvo a non-exclusive
license to the Gene Logic Background Technology as set forth in Section 5.3. In
the event that AgrEvo does not provide written notice within such 90-day period,
AgrEvo shall be deemed to have elected to continue the Research Term. In the
event that AgrEvo elects Alternative E, AgrEvo will pay to Gene Logic (or its
successor) [ * * * ] upon the last day of the Research Term. AgrEvo shall also
pay to Gene Logic (or its successor) [ * * * ] on the fifth anniversary of the
last day of the Research Term in order to maintain the license under Section
5.3. In addition, during the one-year period following the Research Term, AgrEvo
will pay to Gene Logic on a quarterly basis, in arrears, for those Gene Logic
Scientific FTEs necessary to complete the establishment of the license based on
a plan agreed by the parties.

                 (b)      For purposes of this Agreement, a "Change in Control"
of Gene Logic shall be deemed to have occurred in the event of (i) a merger or
consolidation of Gene Logic with another corporation, not including any merger
or consolidation if immediately thereafter the stockholders of Gene Logic
immediately before such transaction own shares representing more than 50% of the
outstanding voting securities of the surviving corporation, (ii) a sale of
shares by the stockholders of Gene Logic if immediately thereafter the
stockholders of Gene Logic immediately before such sale own shares representing
50% or less of the outstanding voting securities of the surviving corporation,
or (iii) a sale of all or substantially all of Gene Logic's assets.

        12.3     ASSIGNMENT. This Agreement shall not be assignable by either
party without the prior written consent of the other party, such consent not to
be unreasonably withheld or delayed, except a party may make such an assignment
without the other party's consent to Affiliates or to a successor to
substantially all of the business of such party, whether in merger, sale of
stock, sale of assets or other transaction; provided, however, that in the event
of such transaction, no intellectual property rights of any Affiliate or Third
Party that is an acquiring party shall be included in the technology licensed
hereunder. This Agreement shall be binding upon and inure to the benefit of the
parties' successors, legal representatives and assigns.

        12.4     NON-WAIVER. The waiver by either of the parties of any breach
of any provision hereof by the other party shall not be construed to be a waiver
of any succeeding breach of such provision or a waiver of the provision itself.

        12.5     GOVERNING LAW. This Agreement shall be construed and
interpreted in accordance with the laws of the State of Maryland other than
those provisions governing conflicts of law.

        1.       PRINCIPAL REPAYMENT. The outstanding principal amount of the

provided in paragraph 4 below, upon January 15, 1999 (the "Maturity Date").

principal amount hereof at any time.

        3.       PLACE OF PAYMENT. All amounts payable hereunder shall be

under this Note on the date the same becomes due and payable or within five (5)
calendar days thereafter;

                 (b)      Borrower files any petition or action for relief
