3.  Cooperative Development Work.

    3.1   Period; Objective.  From the Effective Date, Agritope, Sunseeds and
A&W shall work together to develop and obtain any required Regulatory Approval
for Products for STA.  STA shall from time-to-time approve specific Projects
for different varieties of Product within the Field.  In connection with such
efforts, Sunseeds will furnish to Agritope tomato germplasm for the particular
varieties to be developed in the Projects.  Agritope will implant its genetic
material into such germplasm.  Sunseeds will make the foundation seed and
hybrid seed.  Sunseeds will conduct the breeding activities.  Agritope and A&W
will participate in the breeding activities, including selection of hybrid
seed from foundation seed.  A&W will supply the production acreage and
distribution infrastructure for the development and testing of the Product.

    3.2   Production Testing; Agreement On Cost Savings.  At such time as
Agritope and Sunseeds conclude that a particular variety of Product is ready
for production testing, they will so notify A&W.  Using seeds provided by
Sunseeds, A&W will then provide approximately 3-5 acres for production testing
of such variety (covering as broad a range of growers and as many locations as
possible) and will grow, or cause Approved Growers to grow, fruit under
conditions resembling as nearly as possible the conditions of large scale
commercial growing.  STA will keep detailed records of the cost of growing,
picking and packing such fruit, of the quantity produced, and of shrinkage,
and will furnish such records to Agritope and Sunseeds.  A&W will cooperate,
and will obtain the cooperation of each Approved Grower, to furnish to STA
information that STA may reasonably require for such record keeping.  A&W will
also grow, or cause Approved Growers to grow, and furnish to STA the same
information concerning the cost of growing, picking and packing, and shrinkage
of, an equivalent quantity of fruit of similar variety using seeds of the type
A&W is then using most commonly in its commercial operations (the "Comparison
Tomato").  Based upon such information (and other industry information as is
available concerning growing, picking and packing of such tomato varieties)
STA will determine in good faith the dollar amount per Box that may be
reasonably expected to be saved by use of such Product, instead of the
Comparison Tomato, in large scale commercial growing, picking and packing. 
Such dollar amount per Box, will be referred to in this Agreement as the
"Savings Per Box."  STA will inform Agritope, Sunseeds and A&W of such
determination and provide them with the data supporting such determination.

    3.3   Exchange Of Information.  During the term of the Cooperative
Development Work, Agritope and Sunseeds will exchange with each other and
share with STA all material information developed pursuant to the Cooperative
Development Work, excluding the exchange of Agritope Know-How and information
concerning Agritope Patents and Sunseeds Know-How and information concerning
Sunseeds Patents, relating to the Field.  Agritope and Sunseeds will also
furnish to A&W all information concerning the Product that is pertinent to its
production testing.  A&W will share with STA and the other parties all
material information concerning the Product developed by A&W in the course of
growing, picking and packing the Product, including quantity and cost.

    3.4   Funding.

          (a)   STA shall fund the Cooperative Development Work for each
Project on a full cost-reimbursement basis in accordance with budgets pre-
approved by STA.  STA will have no obligations to fund any expenditures that
are not within such approved budgets.  STA will not reimburse parties for any
costs incurred prior to the date of this Agreement.

          (b)   Each party shall maintain detailed records which accurately
identify costs and expenses incurred and paid in connection with the
Cooperative Development Work for each specific Project.  Each party shall
submit this information to STA as of the last day of each month (or such
alternative dates as STA may establish) for the preceding month and shall
submit to STA on January 15 and July 15 of each year an estimate of expenses
to be incurred during the current six months.

4.  Production And Supply Of Seeds.

    4.1   Sunseeds Responsibilities.  Sunseeds will produce and store seeds
for Product and ship such seeds on behalf of and at the direction of STA.  STA
will remit to Sunseeds Sunseeds' Cost of Goods for such seeds from STA's
proceeds of sale of such seeds.  Sunseeds shall at all times use its best
efforts to supply STA's demand for seeds for Product.

    4.2   Seed Allocations.

          (a)   A&W will have the first right each season to obtain its
requirements of seeds for Product.  A&W will provide to STA A&W's forecasts
for seed six months prior to anticipated shipment, and firm orders for seed
(which will not deviate from forecast by more than twenty percent (20%)) 60
days prior to shipment, which orders must be placed by June 1 and December 1
of each year.  To the extent firm orders are not received by such dates, STA
may allocate available seeds to third parties.  A&W will pay to STA, no later
than thirty (30) days after invoice, STA's Cost of Goods for such seeds, plus
fifteen percent (15%) of such Cost of Goods.

          (b)   If seeds remain in excess of A&W's requirements, STA may
supply such seeds to third party Approved Growers on the such terms as STA
deems advisable.

    4.3   Seed Specifications.  Sunseeds shall supply seed for Product that
shall meet the specifications for such seed as approved in writing by STA.

    4.4   Failure Of Sunseeds To Meet STA Requirements.  To the extent that
Sunseeds cannot meet STA's requirements for seed for Product, STA shall be
free to obtain such seeds from a third party or parties.  Sunseeds agrees to
provide the third party that STA selects with the necessary information and
Sunseeds Know-How to allow the third party to produce the seeds.  As a
condition to the disclosure to the third party, the third party will execute a
non-disclosure agreement substantially in the form of Exhibit A of this
Agreement.

    4.5   Restricted Rights; Labels.  A&W will have the right to use the seed
furnished under this Agreement solely to produce fruit in accordance with the
terms of this Agreement and shall require Approved Growers not to propagate
the seed or use it for other purposes.  Sunseeds and A&W shall insure that all
seeds provided under Section 4 and under Section 3.2 shall be provided under a
label containing either the words "Unauthorized Propagation Prohibited" or
"Unauthorized Seed Multiplication Prohibited" and, after a certificate issues
under the U.S. Plant Protection Act, words such as "U.S. Protected Variety". 
Seeds transferred outside the United States will be transferred under
comparable labels appropriate in the country to which the seeds are
transferred.

5.  Marketing And Distribution Rights.

    5.1   Commercialization.  A&W shall use best efforts to arrange for
Approved Growers to grow fresh tomato Product, and to market and sell fresh
tomato Product in the Territory.  STA will not fund or reimburse any growing,
picking, packing or distribution costs for production or sale of Product
(including those expenses incurred pursuant to Section 3.2).  A&W will market
and sell all tomato Product under a trade name and mark to be determined by
STA, which trade name and mark will be owned solely by STA.

    5.2   Reserved Right To Compete.  Each party expressly reserves the right
to research, develop and market products (expressly including tomato products)
which compete indirectly or directly with the Products developed and marketed
under this Agreement.

6.  Sharing Of Savings And Premium.

    6.1   Applicable Royalty Percentage.  STA, in consultation with the other
parties to this Agreement, and with the concurrence of at least two of the
three other parties, will establish an Applicable Royalty Percentage for each
variety of Product based on the Savings Per Box established pursuant to
Section 3.2.  In conjunction with its commercialization efforts, A&W will
require each Approved Grower to agree in writing to pay to STA, the Applicable
Royalty Percentage.  Any exceptions to the standard Applicable Royalty
Percentage must be approved in writing by STA.  In the event that A&W desires
to act as an Approved Grower, the Applicable Royalty Percentage for A&W will
be the Applicable Royalty Percentage established by STA or such other
Applicable Royalty Percentage as STA and A&W shall negotiate.  Notwithstanding
any other provision hereof, no Approved Grower (including A&W) will receive
any seed for Product, until such Approved Grower has entered into an agreement
in form and substance satisfactory to STA committing to pay the Applicable
Royalty Percentage.  

    6.2   Sharing Payments.  In consideration of the Cooperative Development
Work to be undertaken and other obligations set forth herein, A&W agrees to
pay STA as follows:  No later than thirty (30) days after the first and all
subsequent calendar months following the first sale of Product, A&W shall pay
to STA for each variety of Product an amount equal to the Applicable Royalty
Percentage multiplied by Net Sales of such variety of Product shipped in such
month by A&W and by Approved Growers arranged by A&W.  The Sharing Payments
due and payable hereunder shall be computed for each calendar month in the
currency in which the sale was made, but shall be definitively discharged by
payment to STA in U.S. dollars converted from such currency using the closing
spot exchange rate between the two currencies quoted in the Wall Street
Journal (or, if not available, such other mutually agreeable financial
publication of international circulation) in effect on the last business day
of the calendar quarter to which the payment relates.

16. Infringement; Third Party Licenses.

    16.1  Defense Of Third Party Infringement Suits.  In the event that a
third party shall make any claim or sue any party alleging that the production
or sale of a Product (including, without limitation, seeds), infringes a
patent of such third party, then STA shall have the option to control the
defense of such suit.  The parties shall provide reasonable cooperation in the
defense of such suit and furnish all evidence in their control.  All
attorneys' fees as well as any judgments, settlements, or damages payable with
respect to such claim or suit shall be the responsibility of STA. 
Notwithstanding the foregoing, if the claim or suit alleges that the third
party's rights are infringed solely by technology licensed to STA by one of
the three other parties to this Agreement, such party will indemnify, hold
harmless and defend the other two of such parties from and against any
judgments, settlements or damages they may be required to pay with respect to
such suit.  The indemnifying party will have the sole right to control the
defense of such claim or suit.  No party shall enter into any settlement that
materially affects the other party's rights or interests without such other
party's prior written consent, which consent shall not be unreasonably
withheld.

    16.2  Suits For Infringement By Others.  In the event any party becomes
aware of any actual or threatened infringement in the Field of the Agritope
Licensed Patents or the Agritope Licensed Know-How, or the Sunseeds Licensed
Patents or Sunseeds Licensed Know-How, that party shall promptly notify STA
and STA shall determine the most appropriate action to take.  In the event STA
does not take action against such alleged infringer within a reasonable
period, not to exceed one hundred eighty (180) days, the owner of such patent
rights or know-how shall be entitled to take action against the alleged
infringer.

    16.3  Third Party Licenses.  In the event that STA determines that it is
necessary or advisable to obtain a license from a third party with respect to
development, production or sale of Products, Agritope, Sunseeds and A&W will
make equal contributions to the capital of STA to pay the amount of any lump
sum license fee payable to such third party and the Applicable Royalty
Percentage will be increased by the amount of royalty payable to such third
party on the sale of Products.

17. General.

    17.1  Entire Agreement.  This Agreement, the Operating Agreement and the
Schedules hereto and thereto contain the entire agreement between the parties
relating to the subject matter hereof and all prior understandings,
representations and warranties between the parties are superseded; provided,
however, that this Agreement does not limit any agreement restricting
disclosure or use of confidential or proprietary information previously
entered into between the parties.  None of the terms of this Agreement shall
be deemed to be waived or amended by any party unless such a waiver or
amendment specifically references this Agreement and is in writing signed by
the party to be bound.

    17.2  Relationship Of Parties.  Each party acknowledges that it is not an
agent of any other party to this Agreement and has no authority to speak for,
represent, or obligate such other party in any way (except in the case of
Agritope, acting in its capacity as Manager of STA).  This Agreement does not
and shall not be deemed to create any relationship of a joint venture or a
partnership.

    17.3  Severability.  The parties do not intend to violate any public
policy or statutory or common law.  However, if any sentence, paragraph,
clause or combination of this Agreement is in violation of any law or is found
to be otherwise unenforceable by a court from which there is no appeal, or no
appeal is taken, such sentence, paragraph, clause, or combination of the same
shall be deleted and the remainder of this Agreement shall remain binding,
provided that such deletion does not alter the basic structure of this
Agreement.  In such event, the parties shall renegotiate this Agreement in
good faith, but should such negotiations not result in a new agreement with
ninety (90) days of the initiation of such negotiations, then this Agreement
may be terminated by any party by thirty (30) days notice to the other.

    17.4  Force Majeure.  Any party shall be excused from the performance of
its obligations under this Agreement and shall not be liable for damages to
the other if such performance is prevented by circumstances beyond its
effective control.  Such excuse from performance shall continue so long as the
condition responsible for such excuse continues and for a thirty (30) day
period thereafter.  For the purposes of this Agreement, circumstances beyond
the control of a party which excuse that party from performance shall include,
but shall not be limited to, acts of God, acts, regulations or laws of any
government including currency controls, war, civil commotion, commandeer,
destruction of facility or materials by fire, earthquake, storm or other
casualty, labor disturbances, judgment or injunction of any court, epidemic,
and failure of public utilities or common carrier.

    17.5  Notices.  All notices and demands required or permitted to be given
or made pursuant to this Agreement shall be in writing and shall be effective
when personally given or made or when placed in an envelope and deposited in
the United States certified mail postage prepaid, return receipt requested,
addressed as follows:

                           NON-DISCLOSURE AGREEMENT

                              (MUTUAL DISCLOSURE)


This Agreement is incorporated by reference in the Development and Marketing
Agreement by and among, Superior Tomatoes Association, L.L.C. ("STA"),
Agritope, Inc., Sunseeds, Inc. and Andrew and Williamson Sales Company, Inc.
to assure the protection and preservation of the confidential and or
proprietary nature of information to be disclosed or made available to each
other in connection with the activities under such Development and Marketing
Agreement and the business of STA.

Whereas, the parties desire to assure the confidential status of the
information which may be disclosed to each other;

Now Therefore, in reliance upon and in consideration of the following
undertakings, the parties agree as follows:

1.Subject to the limitations set forth in Paragraph 2, all information
disclosed to another party to this Agreement shall be deemed to be
"Proprietary Information."  The term "Proprietary Information" shall include
trade secrets, confidential knowledge, data or any other proprietary
information.  By way of illustration but not limitation, "Proprietary
Information" includes (a) inventions, trade secrets, ideas, processes,
formulas, source and object codes, data, programs, other works of authorship,
compounds, cell lines, know-how, improvements, discoveries, developments, test
results, designs and techniques; and (b) information regarding plans for
research, development, new products, marketing and selling, business plans,
budgets and unpublished financial statements, licenses, prices and costs,
suppliers and customers; and information regarding the skills and compensation
of employees of a party.

2.The term "Proprietary Information" shall not be deemed to include
information which the receiving party can demonstrate by competent written
proof: (i) is now, or hereafter becomes, through no act or failure to act on
the part of the receiving party, generally known or available; (ii) is known
by the receiving party at the time of receiving such information as evidenced
by its records; (iii) is hereafter furnished to the receiving party by a third
party, as a matter of right and without restriction on disclosure; or (iv) is
independently developed by the receiving party without any breach of this
Agreement.

3.Each party shall maintain in trust and confidence and not disclose to any
third party, or use for any purpose other than activities under such
Development and Marketing Agreement and the business of STA, any Proprietary
Information received from the other party.  Proprietary Information shall not
be used for any purpose or in any manner that would constitute a violation of
any laws or regulations, including without limitation the export control laws
of the United States. No other rights or licenses to trademarks, inventions,
copyrights, or patents are implied or granted under this Non-Disclosure
Agreement.

4.Proprietary Information supplied shall not be reproduced in any form except
as required to accomplish the intent of this Agreement.

5.The responsibilities of the parties are limited to using their reasonable
and best efforts to protect the Proprietary Information received with the same
degree of care used to protect their own Proprietary Information from
unauthorized use or disclosure. Each party shall advise its employees or
agents who might have access to such Proprietary Information of the
confidential nature thereof. No Proprietary Information shall be disclosed to
any officer, employee or agent of either party who does not have a need for
such information.

6.All Proprietary Information (including all copies thereof) shall remain the
property of the disclosing party, and shall be returned to the disclosing
party after the receiving party's need for it has expired, or upon request of
the disclosing party, and in any event,  upon completion or termination of
this Agreement.

7.Notwithstanding any other provision of this Agreement, disclosure of
Proprietary Information shall not be precluded to the extent such disclosure
is required to be disclosed by the Receiving Party by judicial action provided
that the receiving party shall immediately notify the disclosing party of any
such action and the disclosing party shall have the opportunity to pursue all
reasonable legal remedies to maintain such information in secret.

8.This Agreement shall continue in full force and effect for so long as the
parties continue to exchange Proprietary Information.  The termination of this
Agreement shall not relieve either party of the obligations imposed by this
Agreement with respect to Proprietary Information disclosed prior to the
effective date of such termination, and the provisions of these paragraphs
shall survive the termination of this Agreement.

9.This Agreement shall be governed by the laws of the State of California as
those laws are applied to contracts entered into and to be performed entirely
in California by California residents.

10.This Agreement contains the entire agreement of the parties concerning use
and protection of Proprietary Information and may not be changed, modified,
amended or supplemented except by a written instrument signed by each party.

11.Each party hereby acknowledges and agrees that in the event of any breach
of this Agreement by another party, including, without limitation, the actual
or threatened disclosure of a disclosing party's Proprietary Information
without the prior express written consent of the disclosing party, the
disclosing party will suffer an irreparable injury, such that no remedy at law
will afford it adequate protection against, or appropriate compensation for,
such injury. Accordingly, each party hereby agrees that such other party shall
be entitled to specific performance of a receiving party's obligations under
this Agreement, as well as such further injunctive relief as may be granted by
a court of competent jurisdiction.
