ARTICLE 2. GRANT OF LICENSE

2.1   Nutraceutix Licensed Patents.
      For the term of this Agreement and subject to the terms and conditions
      hereof, Nutraceutix hereby grants to ADM (i) the sole and exclusive right
      and license, with the right to sublicense, to manufacture, have
      manufactured on its behalf, use, sell and offer to sell the Licensed
      Products and the Inventions in the Territory for the Exclusive Licensed
      Field of Use; and (ii) the non-exclusive right and license, with the right
      to sublicense, to manufacture, have manufactured on its behalf, use, sell
      and offer to sell the Licensed Products and the Inventions in the
      Territory for the Non-exclusive Licensed Field of Use. Nutraceutix shall
      not grant other licenses under the Licensed Patents in the Territory for
      the Exclusive Licensed Field of Use. Further, subject to the provisions of
      Section 2.4, Nutraceutix does not retain any rights to manufacture, have
      manufactured, use, sell, market, offer for sale or import Licensed
      Products and/or Inventions in the Territory for the Exclusive Licensed
      Field of Use.

2.2   Improvements.
      Nutraceutix shall promptly disclose to ADM any improvements to the
      Inventions that are invented, conceived, made, developed, discovered,
      first reduced to practice or created by Nutraceutix, its employees or
      agents, during the term of this Agreement and that apply to Licensed
      Products. ADM shall have the option to license any such improvements and
      any patents or patent applications therefor, and if ADM so exercises its
      option then the same shall come under this Agreement and be subject to the
      terms and provisions hereof. Nutraceutix may file for patent protection
      for any such improvements as it sees fit at its cost. If Nutraceutix fails
      to pursue patent protection to the extent desired by ADM, and ADM
      exercises its option hereunder, then ADM may pursue such patent
      protection, at its cost, in the name of Nutraceutix after providing
      Nutraceutix with thirty (30) days advance written notice thereof and
      Nutraceutix failing to take such action itself during such period of time.
      Each party shall provide cooperation to the other party to execute any
      documents necessary to effectuate such patent protection.

2.3   Right of Refusal.

      (a)   Notice of Offer. If Nutraceutix makes or receives a bona fide offer
            ("Offer") to sell, assign, license or otherwise transfer any
            interest in the Inventions or Licensed Patents outside the Licensed
            Field of Use but with respect to any nutraceutical or dietary
            supplement (the "Option Intellectual Property") to a third-party,
            Nutraceutix shall promptly, but no later than ten (10) days after
            the Offer is made or received, as the case may be, give written
            notice thereof to ADM (the "Notice"). Notwithstanding any provision
            hereof to the contrary, if the Offer is rejected by Nutraceutix,
            Nutraceutix shall not be required to give the Notice to ADM and ADM


                                       5
<PAGE>
            shall not have an Option (as hereinafter defined) with respect to
            the rejected Offer.

      (b)   Form of Notice. The Notice, in addition to disclosing the existence
            of the Offer, shall state: (i) the name, business and residence
            address of the proposed purchaser or licensee; (ii) the aggregate
            amount of the proposed consideration, including royalties; and (iii)
            all other material terms of the Offer, including a detailed
            description of the subject intellectual property, the products
            derived from the intellectual property and their applications. If
            the Offer is written, a copy of the Offer shall accompany the
            Notice.

      (c)   Grant of Option. Nutraceutix hereby grants ADM a right of last
            refusal and option (the "Option") to either, at ADM's option, (i)
            consummate the transaction proposed by the Offer upon the terms
            contained in the Notice; or (ii) elect to have the Option
            Intellectual Property come under this Agreement and be subject to
            the terms and provisions hereof. ADM shall have the longer of the
            thirty-day period beginning on the day ADM receives the Notice and
            the period, if any, in which the proposed purchaser must consummate
            the transaction proposed by the Offer (the "Option Period") to make
            its election. During the Option Period, Nutraceutix shall not enter
            into any agreement or contract with respect to an Offer with any
            party other than ADM, unless ADM has notified Nutraceutix in writing
            that it does not intend to exercise the Option or the Option has
            been deemed waived.

      (d)   Non-Exercise of Option. If, within the Option Period, ADM does not
            exercise the Option, Nutraceutix shall be free to consummate the
            proposed transaction with the purchaser or licensee identified in
            the Notice on the same terms and conditions set forth in the Notice.
            If any material change is made in the terms of the Offer, the Offer,
            as changed or amended, shall be deemed a new Offer for the purposes
            of this Agreement and shall be presented to ADM as set forth above.


2.4   Manufacture of Licensed Products.
      If so requested by ADM in writing, Nutraceutix shall either manufacture
            for ADM, or arrange to have a subcontractor of Nutraceutix
            manufacture for ADM, Licensed Products in blend, bulk tablet or
            finished good form. ADM shall pay Nutraceutix for such Licensed
            Products an amount equal to Nutraceutix's or its contractor's
            fully-burdened manufacturing cost therefor plus nine percent (9%).
            ADM shall coordinate such manufacturing with Nutraceutix in such a
            way that Nutraceutix's resources are not unduly burdened thereby.

ARTICLE 3. CONSIDERATION

3.1   Reimbursement of Development Costs.

      (a)   In consideration of the rights and licenses granted to ADM by
            Nutraceutix under this Agreement, ADM shall reimburse Nutraceutix
            for the costs Nutraceutix has incurred in developing and formulating
            Novasoy(R) isoflavones utilizing the Inventions, in the amount of
            US$50,000, such amount to be paid upon Nutraceutix presenting
            support and verification for such costs.


                                       6
<PAGE>
      (b)   In further consideration of the rights and licenses granted to ADM
            by Nutraceutix under this Agreement, ADM may at its option reimburse
            Nutraceutix for the costs Nutraceutix has incurred in developing and
            formulating Vitamin C utilizing the Inventions, in the amount of
            US$150,000, such amount, if paid, to be paid on or before nine (9)
            months from the Effective Date or Nutraceutix presenting ADM with
            support and verification for such costs, whichever is later. If ADM
            fails to remit such amount within such period of time, then the
            Exclusive Licensed Field of Use shall be deemed to not include
            Vitamin C.



3.2   Running Royalties.
      In further consideration of the rights and licenses granted to ADM by
      Nutraceutix under this Agreement, ADM shall further pay Nutraceutix a
      running royalty ("Running Royalty") in United States dollars for each
      Contract Quarter equal to ___% of the Net Sales for Licensed Products
      sold by ADM during such Contract Quarter.

3.3   Payment of Royalties.
      All Running Royalties shall be paid by ADM to Nutraceutix within
      forty-five (45) days after the close of the Contract Quarter.

3.4   Books and Records.
      ADM shall keep and retain for not less than three (3) years after each
      Contract Year in question full, complete and accurate books of account and
      records relating to the manufacture, use and sale or other disposition of
      the Licensed Products by or for ADM in such detail as will enable
      Nutraceutix to ascertain what royalties are due under this Agreement. Such
      books and records shall be consistent with ADM's overall financial
      statements and in compliance with generally accepted accounting principles
      and practices in the United States, consistently applied. ADM shall,
      during business hours and upon reasonable notice, permit an independent
      accounting firm (retained by Nutraceutix) that has entered into a secrecy
      agreement reasonably acceptable to the parties access to such books and
      records for the sole purpose of verifying the royalty accrued as herein
      provided. The verification will take place at Nutraceutix's expense,
      unless the verification indicates that additional amounts are owed to
      Nutraceutix in excess of three percent (3%) of the total amounts due
      during the period of time verified and in that event ADM shall bear the
      expense of the verification.

ARTICLE 4. INFRINGEMENT

4.1   Notification.
      In the event that ADM or Nutraceutix has reason to believe that a third
      party is infringing upon the Licensed Patents, such party shall promptly
      notify the other party in writing of such alleged infringement.

4.2   Infringement Actions.
      Upon notification of potential infringement pursuant to Section 4.1, ADM
      shall have the option to enforce the Licensed Patents in the Licensed
      Field of Use itself or request


                                       7
<PAGE>
     Nutraceutix to enforce the Licensed Patents in the Licenced Field of Use.
     In the event ADM elects to enforce the Licenced Patents, the reasonable
     costs of such action shall be borne by ADM. In the event ADM elects to have
     Nutraceutix enforce the Licenced Patents, ADM shall provide Nutraceutix
     with written notice thereof, and to the extent deemed reasonably necessary
     by ADM, Nutraceutix shall commence an infringement action, in which event
     the reasonable costs of such action shall be borne equally by the Parties.
     In either event, the benefits of any damages recovered (after each party
     recovers any share of its costs of such action) shall be divided in a
     manner that provides Nutraceutix with its Running Royalty and ADM with all
     remaining amounts. In any such infringement action, the party commencing
     the action (the "Participating Party") shall keep the other party (the
     "Non-participating Party") advised of the progress of the litigation and
     shall provide the Non-participating Party with drafts of the pleadings,
     discovery, motions, and briefs prior to filing for the Non-participating
     Party's review and comment. In addition, the Participating Party shall
     consult with the Non-participating Party with regard to every material
     decision required to be made during the litigation. The Participating Party
     shall adopt the Non-participating Party's comments and recommendations
     during the litigation except to the extent they may materially impact the
     Participating Party's commercial best interests, as determined by the
     Participating Party. In any such infringement action or claim brought, the
     Non-participating Party shall upon the Participating Party's request,
     cooperate with the Participating Party in all respects, and make available
     to the Participating Party all relevant information and witnesses who are
     employees or within the control of the Non-participating Party. To the
     extent necessary, each Party agrees to be joined as a party in any
     litigation where it is an indispensable party.

      Licensed Products, and that while ADM shall use Reasonable Efforts,
      ultimately ADM's customers and the end consumer will decide which products
      are preferred. If ADM fails to use Reasonable Efforts with respect to one
      or more Licensed Products, Nutraceutix shall provide ADM with written
      notice thereof, indicating in detail (i) the reasons Nutraceutix believes
      ADM has not used Reasonable Efforts; and (ii) the steps Nutraceutix
      believes are necessary for ADM to use Reasonable Efforts. Within thirty
      (30) days of receiving Nutraceutix's notice, ADM shall send a written
      reply to Nutraceutix indicating whether ADM agrees or disagrees. If ADM
      agrees with Nutraceutix's assessment, ADM at its option shall elect to
      either (i) take the additional steps Nutraceutix set forth as soon as
      reasonably possible; or (ii) elect to convert the license granted in
      Section 2.1 to a non-exclusive license with respect to the Licensed
      Products in issue, in which case ADM has no obligation to take the
      additional steps set forth by Nutraceutix. If ADM disagrees with
      Nutraceutix's assessment, ADM shall provide Nutraceutix with detailed
      reasons therefor and shall propose a meeting time and place to discuss the
      matter. The parties shall meet to discuss the matter within thirty (30)
      days of Nutraceutix's receipt of ADM's reply at a mutually agreeable time
      and place. If the parties fail to reach an agreement at such meeting, the
      matter shall be treated as a Dispute and handled pursuant to Article 11.
      If the finding from an arbitration is that


                                       10
<PAGE>
      ADM has not used Reasonable Efforts, ADM shall elect within thirty (30)
      days of receiving such arbitration award to either (i) take the additional
      steps Nutraceutix set forth in its original notice as soon as reasonably
      possible; or (ii) elect to convert the license granted in Section 2.1 to a
      non-exclusive license with respect to the Licensed Products in issue, in
      which case ADM has no obligation to take the additional steps set forth by
      Nutraceutix.

ARTICLE 8. PACKAGING, LABELS AND PROMOTIONAL ITEMS
--------------------------------------------------

      All packaging, labels and promotional items used or associated with the
      Licensed Products shall be marked prominently with all marks required by
      the laws and regulations of each country in the Territory in which the
      same will be marketed, sold or used for marketing of patented items and
      which are necessary or appropriate to maintain the patent protection of
      the Licensed Patents or other Intellectual Property rights licensed
      pursuant to this Agreement. ADM shall obtain Nutraceutix's written
      approval of all such packaging, labels and promotional items which include
      any trademark or logo owned by Nutraceutix prior to using the same in
      commerce, which approval shall not be unreasonably withheld or delayed.
      Subject to the foregoing, Company shall be solely responsible for all
      packaging, labels and promotional items for the Licensed Products.

ARTICLE 9. PROTECTION OF PROPRIETARY RIGHTS
-------------------------------------------

      ADM acknowledges that the Licensed Products, the Inventions and the
      Licensed Patents involve valuable Intellectual Property rights of
      Nutraceutix and its licensor. Nutraceutix and its licensor reserve all
      such Intellectual Property. ADM shall not infringe or violate, and shall
      take appropriate precautions for the protection of, such Intellectual
      Property. Without limiting the generality of the foregoing, ADM shall not
      apply for or attempt to obtain any Intellectual Property or other
      proprietary rights in the Licensed Products, the Inventions, the Licensed
      Patents, or any other item licensed pursuant to this Agreement. No title
      to or ownership of the Licensed Products, the Inventions, the Licensed
      Patents, or any other item licensed pursuant to this Agreement is
      transferred pursuant to or by virtue of this Agreement or any use by ADM
      of the Licensed Products, the Inventions, the Licensed Patents, or any
      other item licensed pursuant to this Agreement.

ARTICLE 10. ASSIGNMENT
----------------------

10.1  Permitted Assignment Only.
      --------------------------
      Neither this Agreement nor the licenses granted herein may be assigned by
      either of the Parties without the prior written consent of the other
      Party, except, however, (i) Nutraceutix may assign this Agreement to a
      third party acquiring the entire business or substantially all of the
      assets of Nutraceutix provided Nutraceutix also assigns to that party all
      of its rights to the inventions and Licensed Patents within the Licensed
      Field of Use and Nutraceutix provides ADM with written notice thereof on
      or before the effective date of such assignment; (ii) ADM may assign this
      Agreement and the licenses granted herein to an Affiliate or to a third
      party acquiring the entire business or substantially all of the assets of
      ADM to which this Agreement pertains, provided that at the time of the

                                       11


<PAGE>
assignment, the assignability of this License Agreement will not adversely
affect Nutraceutix's rights under the terms of this agreement including its
royalties, and provided ADM provides Nutraceutix with written notice thereof on
or before the effective date of such assignment. Any purported assignment or
transfer in violation of this provision shall be null and void.

10.2 Successors and Assigns.

     In the event of a permitted assignment, this Agreement shall be binding
     upon, and inure to the benefit of, all the Parties and their respective
     successors and legal assigns.


ARTICLE 11.  DISPUTES; ARBITRATION

Any dispute, questions, or differences relating to this Agreement, (collectively
"Disagreements") shall be settled, if possible, amicably between the Parties.
Any Disagreements, if not settled by the parties within fifteen (15) days from
the date the disagreement arises, shall be considered a dispute ("Dispute"), and
shall be referred to an executive from each of ADM and Nutraceutix who have
authority to settle the Dispute. If any such Dispute which has not been resolved
by such executives within thirty (30) days after the date it was first referred
to them, ADM and Nutraceutix shall proceed to binding arbitration in accordance
with this Article.

(1)  The arbitration shall be held in Chicago, Illinois if either Party demands
     arbitration.

(2)  The arbitration shall be conducted by three (3) arbitrators in accordance
     with the Rules of the American Arbitration Association, except as
     expressly set forth herein. Each Party shall promptly select an
     arbitrator, and those two arbitrators shall select the third arbitrator.

(3)  The arbitration shall be conducted in English, and all written submissions
     shall be in English.

(4)  The Parties agree that the decision of the arbitrators shall be final and
     binding on the Parties and judgment upon the award rendered by the
     arbitrators my be entered in any court having jurisdiction thereof.

(5)  The Parties agree that the prevailing party in any arbitration shall be
     entitled to recover its costs of the arbitration including its reasonable
     attorneys' fees from the losing party and that such recovery will be part
     of the arbitration award.

(6)  The Parties agree that all discovery and all arbitration hearings
     associated with a particular Dispute shall be completed within six (6)
     months from the date the Dispute was first referred to arbitration.

Notwithstanding the foregoing, the provisions of this paragraph shall apply to
any Dispute regarding the amount of money payable by one Party to the other. In
the case of such a Dispute, the Party desiring to invoke arbitration shall,
prior to invoking the arbitration procedure of this Article 11, tender to the
other Party a figure which is


                                       12

<PAGE>
designated as that Party's offer for agreement ("Offer of Agreement"). The
other Party shall, within thirty (30) days thereafter, tender its own Offer of
Agreement. Within fifteen (15) days following such second tender of an Offer of
Agreement each Party shall tender to the other a figure which is designated as
the Party's final offer ("Final Offer"). Each tender of an Offer of Agreement
or Final Offer shall be accompanied by supporting documents. If the Parties
fail to reach agreement within ten (10) days following tender of the Final
Offers, then either Party may invoke the arbitration procedure of this
paragraph; provided that in that event (i) the matter at issue shall be
submitted for determination to a single arbitrator having demonstrated
expertise in establishing the monetary amount at issue, (ii) each Party shall
deliver to the arbitrator a copy of that Party's Final Offer and supporting
documents, and (iii) the arbitrator shall choose one of the Final Offers as the
resolution of the Dispute.

Except for (i) an action to enforce payment of an amount that is not in dispute
by either Party, or (ii) an action to seek injunctive relief to prevent or stay
a breach of this Agreement, or (ii) any action necessary to enforce the award
of the arbitrators, the Parties agree that the provisions of this Article 11
shall be a complete defense to any suit, action or other proceeding instituted
in any court or before any administrative tribunal with respect to any Dispute.


ARTICLE 12. GOVERNING LAW

This Agreement shall be governed by and construed in accordance with the
substantive laws of the state of Illinois, U.S.A., without regard to choice of
law principles.


ARTICLE 13. FORCE MAJEURE

In the event of the intervention of a Force Majeure, which term shall include,
without limitation, strikes, labor disturbances, lockouts, riots, epidemics,
quarantines, wars or conditions of war, actions, inaction or regulations of any
government, fires, acts of terrorists, insurrections, embargoes or trade
restrictions, or any other reasons beyond a Party's control, the Party affected
by the Force Majeure shall use commercially reasonable efforts to comply with
the Agreement. In the case that such commercially reasonable efforts fail or are
futile, such Party shall not be responsible for delays or a failure to perform
under this Agreement caused by a Force Majeure. Provided, however, that any
payment obligations of ADM shall not be affected or excused by such Force
Majeure.

In the event that either Party shall incur a delay in delivery or performance
for a reason permitted by this Article, that Party shall notify the other Party
within fifteen (15) days from the date of the actual occurrence of the cause
for such delay.
