due until actually paid at a rate of [***].

            3.4.4.  All payments made by Licensee under this Agreement shall be
made in United States dollars, and such payments shall be made by check or wire
transfer to one or more bank accounts to be designated in writing by AgraQuest.
In the event that Licensed Products are sold in currencies other than United

received had no such deductions or withholdings been required.

     3.6.   Inspection of Books and Records. Licensee shall maintain, and
require its Sublicensees to maintain, complete and accurate books and records
which enable the calculation of royalties and other payments payable hereunder

records for each quarterly period for ten (10) years after the submission of the
corresponding report under this Section 3.6. Upon two weeks prior notice to
Licensee, AgraQuest or independent accountants selected by AgraQuest may have

after the expiration or termination of this Agreement. In the event of any
underpayment, Licensee shall promptly pay to AgraQuest the difference between
the amount actually paid by Licensee and the amount determined to be owing under
this Section 3.6. Any such inspection or audit shall be at AgraQuest's expense,
unless the inspection or audit results in a determination that Licensee's
payment obligations to AgraQuest have been understated, or that Licensee's
payments have been underpaid, by more than five percent (5%) of the amount
actually paid by Licensee for the period examined, in which case Licensee shall
pay all reasonable costs and expenses incurred by AgraQuest in the course of
making such determination, including the fees and expenses of such accountant.

4.   DUE DILIGENCE

     4.1.   Development Reports. Licensee shall deliver to AgraQuest, within
[***] following the Effective Date, a written report setting forth in reasonable
detail (a) the identity of all Licensed Products or prototype products in
research or manufacturing, (b) the stage of development for each such Licensed

this Article 4, Licensee must (a) provide written reports to AgraQuest in
accordance with Section 4.1 and (b) upon AgraQuest's written and reasonable
request, demonstrate to AgraQuest's satisfaction that it is proceeding with a
Licensed Product in a manner consistent with moving such. If AgraQuest

any such patent application, or elects not to maintain any patent that may issue
therefrom Licensee shall have the right but not the obligation, at Licensee's
option and expense, to file for and prosecute such patent application and
maintain such patent. In such event, (a) AgraQuest agrees to assign and hereby
assigns to AgraQuest all of it right, title and interest in and to such Joint
Patent and (b) Licensee agrees to grant and hereby grants to AgraQuest an
exclusive, royalty-free, non-cancellable, worldwide license in, to and under
Licensee's right, title and interest to such Joint Patent outside the Field, it
being understood that Licensee retains exclusively all rights under such Joint
Patent within the Field. Licensee shall provide AgraQuest with all material

initial right, but not the obligation, as to Licensee to institute, prosecute
and control any action, suit or proceeding (an "Action") with respect to such

[***].

             6.1.2.  In the event AgraQuest fails to initiate any Action
involving the Licensed Patents or Joint Patents within [***] of receiving notice
of any commercially significant infringement, Licensee shall have the right, but
not the obligation, to initiate and/or maintain such Action at its expense, and
AgraQuest shall cooperate reasonably with Licensee, at Licensee's request, in
connection with any such Action. [***].

             6.1.3. If Licensee initiates and maintains an infringement action
on AgraQuest's behalf pursuant to Section 6.1.2 with respect to the infringement
of any Licensed Patents or Joint Patents, Licensee' reasonable and customary
expenses for such action (including attorneys' fees and expert fees) shall be
[***].

             6.1.4. If Licensee initiates and maintains an infringement action
on AgraQuest's behalf pursuant to Section 6.1.2, and subsequently decides to
abandon such an action other than pursuant to a settlement with the alleged
infringer, Licensee shall give AgraQuest timely notice so that AgraQuest or its
licensor may, at its option and if it so desires, continue such action.

     6.2.    Cooperation. In any Action, the parties shall provide each other
with reasonable cooperation and assistance, including agreeing to be named as a
party to such Action, and, upon the request and at the expense of the party
bringing such Action, the other party shall make available, at reasonable times
and under appropriate conditions, all relevant personnel, records, papers,
information, samples, specimens, and the like in its possession. Notwithstanding
any other provision of this Article 6, neither party shall make any settlements
of any suit, proceeding or action relating to an infringement of any Licensed

then those set forth herein. The recipient of the disclosing party's
Confidential Information shall use such Confidential Information solely to
exercise its rights and perform its obligations under this Agreement (including,
without limitation, the right to use and disclose such Confidential Information
in regulatory applications and filings), unless otherwise mutually agreed in
writing. The recipient of the other party's Confidential Information shall take

party as demonstrated by contemporaneous documentation; (b) is or becomes,
through no fault of the recipient, publicly known; (c) is furnished to the
recipient by a third party without breach of a duty to the disclosing party; (d)
is independently developed by the recipient without use of, application of or
reference to the disclosing party's Confidential Information as demonstrated by
contemporaneous documentation.

     10.4.  Legal Disclosures. It shall not be a violation of this Article 10 to
disclose Confidential Information required to be disclosed under applicable law,
but such disclosure shall be only for the sole purpose of and solely to the
extent required by such law, and provided that the recipient, to the extent
possible, shall give the disclosing party prior written notice of the proposed
disclosure and cooperate fully

Agreement.

and interpreted, in accordance with the internal laws of the State of California
(as permitted by Section 1646.5 of the California Civil Code or any similar

laws of the State of California to the rights and duties of the parties.

     11.5.  Export Regulations.  Licensee agrees that this Agreement is subject
in all respects to the laws and regulations of the United States of America,

fees) against the other party.   Each party irrevocably and unconditionally
consents to the jurisdiction of any

such proceeding and waives any objection that it may have to personal
jurisdiction or the laying of venue of any such proceeding.

     11.8.  Force Majeure.  Neither party shall be held responsible for any
delay or failure in performance (with the exception of the payment of money)
hereunder to the extent caused by strikes, embargoes, unexpected government
requirements, civil or military authorities, acts of God, earthquake, or by the
public enemy or other causes reasonably beyond such party's control and without
such party's fault or negligence; provided that the affected party notifies the
unaffected party as soon as reasonably possible, and resumes performance
hereunder as soon as reasonably possible following cessation of such force
majeure event.

     11.12. Modification; Waiver. This Agreement may not be altered, amended or

party to thereafter enforce such rights or provision or any other rights or
provisions hereunder. No waiver shall be effective unless made in writing and
signed by the waiving party.


     11.13.  Severability.  If any provision of any provision of this Agreement
shall be found by a court to be void, invalid or unenforceable, the same shall
be reformed to comply with applicable law or stricken if not so conformable, so
as not to affect the validity or enforceability of this Agreement; provided that
no such reformation or striking shall be effective if the result materially
changes the economic benefit of this Agreement to either AgraQuest or Licensee.
In the event that any provision of this Agreement becomes or is declared by a
court of competent jurisdiction to be void, invalid or unenforceable, and
reformation or striking of such provision would materially change the economic
benefit of this Agreement to either AgraQuest or Licensee, AgraQuest and
Licensee shall modify such provision in accordance with this Section 11.13 to
obtain a legal, valid and enforceable provision and provide an economic benefit
to AgraQuest and Licensee that most nearly effects AgraQuest's and Licensee'
intent on entering into this Agreement.

Agreement, together with the exhibits attached hereto, set forth the entire
agreement and understanding of the parties as to the subject matter hereto, and
