of verifying BioNebraska's royalty statements.

     Section 4. BioNebraska shall, within thirty days of each one year
anniversary of the Effective Date deliver to the Board a true and accurate
report of all transactions relating to the calculation and payment of
royalties pursuant to this Agreement.  Such report shall include, INTER ALIA,
the period of time covered by the report, a description of all products sold
by BioNebraska or its permitted assigns and/or licensees upon which royalties
are due and payable, the number and Net Selling Price of all said products,
all deductions from royalties, and the computation of any royalties due and
payable to the Board by BioNebraska.  Simultaneously with the delivery of
each report, BioNebraska shall pay to the Board the royalty accrued for the
period covered by such report.  If no royalties are due, it shall be so
reported.

     Section 5. Board, BioNebraska and Finnsugar agree that all rights under
this license shall revert back to Board effective one month after
notification by Board if neither of the following have occurred:

     (a)  Covered Products or Licensed Products are offered for sale by
          BioNebraska or by a sublicensee of BioNebraska within two years
          after the date of this agreement or for any two consecutive years
          thereafter; or

     (b)  funds are made available to Board to continue work at facilities of
          Board within six months of Effective Date at a level of at least
          [CONFIDENTIAL TREATMENT REQUESTED] semiannually and continue for at
          least two years.

     Section 6. If at any time during the term of this agreement after the
quarterly report occurring after the fourth anniversary date (beginning of
fifth year) of the agreement and before the end of the ninth year, the amount
of yearly Paid Royalties on a cumulative basis falls below that indicated in
the following table after the year to which it applies, Board may upon thirty
days written notice convert this license to a non-exclusive license and seek
other non-exclusive licensees.  In such an event, all other terms of this
agreement remain the same:

     Fifth year          [CONFIDENTIAL TREATMENT REQUESTED]
     Sixth year          [CONFIDENTIAL TREATMENT REQUESTED]
     Seventh year        [CONFIDENTIAL TREATMENT REQUESTED]
     Eighth year         [CONFIDENTIAL TREATMENT REQUESTED]
     Ninth year          [CONFIDENTIAL TREATMENT REQUESTED]

     This section 6 of article III shall not apply after such time as the
Board has received not less than [CONFIDENTIAL TREATMENT REQUESTED] in Paid
Royalties.

     Section 7. BioNebraska shall exercise best efforts to commercialize
University of Nebraska Inventions in Nebraska or to locate a licensee that
will commercialize the University of Nebraska Inventions in Nebraska.

                                 ARTICLE IV
                            TERM AND TERMINATION

     Section 1.  This Agreement shall remain in full force and effect for the
longer of ten years or the life of any patent (issued in the United States or
elsewhere) which embodies the University of Nebraska Inventions which are the
subject of this Agreement.

     Section 2.  If Finnsugar or BioNebraska shall become bankrupt or
insolvent and/or the business of Finnsugar or BioNebraska shall be placed in
the hands of a receiver, assignee or trustee, whether by the voluntary act of
BioNebraska or otherwise, this Agreement shall become void effective thirty
days following the effective date of such written notice, unless the breach
or default is cured prior to the expiration of this thirty-day period.  It
shall be considered a breach or default to fail to pay money owed to the
Board by BioNebraska, or to use the Board's name by BioNebraska or by
Finnsugar in a manner that is not approved of by the Board and which may call
into question the propriety of any of the Board's actions.

     Section 3.  Termination of this Agreement shall not affect the
obligations of BioNebraska to pay any royalty or other payments which may be
due and unpaid at the date of termination, nor shall it prejudice any other
right of the Board under this Agreement.  Within sixty days after
termination, BioNebraska shall render to the Board a written statement of the
kind required in article III hereof respecting the due and unpaid royalties
and shall accompany such a statement with a payment to cover the same.

                                 ARTICLE IV
                               MISCELLANEOUS

     Section 1.  To the extent the terms of this agreement are inconsistent
with any earlier agreements with respect to research funded by Finnsugar and
conducted by the Board, the terms of this agreement shall apply.

     Section 2.  Nothing contained in this Agreement shall be construed as:

     (a)  a warranty or representation of any party as to the validity or
          scope of any patent obtained on the University of Nebraska
          Inventions, except that the parties warrant that they will act in
          good faith without fraud with respect to the filing and prosecution
          of any patent applications;

                                      9
<PAGE>

     (b)  a warranty or representation that any manufacture, sale, lease or
          use of any products embodied by the University of Nebraska
          Inventions will be free from infringement of patents owned by any
          third party;

     (c)  an agreement to bring or prosecute actions or suits against third
          parties for infringement, the right to bring or prosecute said
          actions or suits residing solely in BioNebraska or in Board or in
          Finnsugar; or

     (d)  conferring to either party any right to use in advertising,
          publicity, or otherwise any name, trade name, or trademark, or any
          contraction, abbreviation or simulation thereof of the other party.

     Section 3.  The construction and performance of this agreement shall be
governed by the laws of the State of Nebraska.

     Section 5.  The headings of this Agreement are intended merely to
facilitate reference and shall have no bearing upon the interpretation of any
terms of this Agreement.

     Section 6.  Nothing in this Agreement constitutes permission to use the
name of the University of Nebraska or the Board of Regents of the University
of Nebraska or the names of the Inventors without the express written
permission of the Board, except as expressly authorized in this Agreement.

     Section 7.  Neither party shall be liable to the other for any loss,
damage or default occasioned by strike, civil disorder, governmental decree
or regulation, acts of God or any other force majeure.  In the event of the
occurrence of such force majeure, the term of this Agreement will be
suspended and extended for the duration of such force majeure.

     Section 8.  This Agreement may not be modified and limited and none of
its terms may be waived except by agreement in writing signed by both
parties. The failure of either party to enforce, or the delay by either party
in enforcing any of their rights shall not be deemed a continuous waiver or
modification of this Agreement.

     Section 9.  This agreement is severable.  If any term of it is found to
be illegal or unenforceable, the contract shall be interpreted as though that
term was omitted and the contract shall remain valid to the extent possible.
In determining severability, the rights in article II are consideration for
the duty to file patent applications, transfer rights from Finnsugar to
BioNebraska, and the requirements to pay certain minimum amounts of royalties.

     Section 10.  The parties hereto specifically contemplate and agree that
within three months of the Effective Date and without any further permission
or action required from the parties hereto:

     (1)  Finnsugar shall transfer all of its rights under this Agreement
          including its rights to Inventions to BioNebraska and that

          Finnsugar as to such rights and shall exclusively thereafter enjoy
          all of the rights conferred herein upon Finnsugar; and

     (2)  the obligations of Finnsugar to Board created by this agreement
          except those created by virtue of Finnsugar's ownership of stock in
          BioNebraska or Finnsugar's control of BioNebraska or the obligation
          to pay patent expenses under article II, sections 4-7,

                                      11

          obligations and shall exclusively thereafter bear all of the
          obligations to Board conferred herein upon Finnsugar.
