                                          3


                                    ARTICLE III
                           REPRESENTATIONS AND WARRANTIES

     3.1  METAGENICS represents and warrants that it is the owner of the entire
right, title, and interest of LICENSED PATENT RIGHTS and that it has full right

     3.3  METAGENICS represents and warrants that, as of the EFFECTIVE DATE of
this Agreement, there is no threatened or pending litigation by or against

                                     ARTICLE IV
                                    COMPENSATION

     4.1  GALAGEN agrees to pay METAGENICS an initial fee of [***CONFIDENTIAL

EXCHANGE COMMISSION***]for the SOLE license of Paragraph 2.1 granted to GALAGEN
herein payable within 15 days of the EFFECTIVE DATE of this Agreement.

     4.2  [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION***].

     4.3  [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION***]

     4.4  In the event that GALAGEN grants a sublicense to a third party, in

sublicense, GALAGEN shall pay METAGENICS a payment of [***CONFIDENTIAL TREATMENT

COMMISSION***] of such initial fee, if any, within 30 days of GALAGEN's receipt
of the initial fee from the sublicensee.

     4.5  GALAGEN shall pay METAGENICS a royalty of [***CONFIDENTIAL TREATMENT
REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION***] of the NET SALES PRICE for each


                                          4


LICENSED PRODUCT sold under this Agreement, provided that each such LICENSED
PRODUCT is made, used, imported from or into, offered for sale, sold or
otherwise distributed by GALAGEN, a third party on behalf of GALAGEN, or a
sublicensee, in a country in which METAGENICS owns or controls LICENSED PATENT
RIGHTS containing a pending or valid, unexpired, enforceable patent claim
covering such making, using, importing from or into, offering for sale and/or
sale of such  LICENSED PRODUCT.

     4.6  With respect to LICENSED PRODUCT(S) SOLD by or for a sublicensee,
GALAGEN, in GALAGEN's discretion, may cause the sublicensee to pay royalties in
accordance with this Article IV directly to METAGENICS or GALAGEN may cause the
sublicensee to pay an amount of royalties to GALAGEN.  If GALAGEN causes a
sublicensee to pay an amount of royalties to GALAGEN for sales by the
sublicensee, GALAGEN shall thereafter be responsible for paying royalties for
such sales to METAGENICS in accordance with this Article IV.

     4.7  With respect to each LICENSED PRODUCT SOLD by or for GALAGEN,
royalties payable to METAGENICS under this Article IV for such sale shall be
deemed to accrue when such LICENSED PRODUCT is first SOLD.

     4.8  With respect to each LICENSED PRODUCT SOLD by or for a sublicensee for
which GALAGEN has caused such sublicensee to pay royalties directly to
METAGENICS, royalties payable to METAGENICS under this Article IV for such sale
shall be deemed to accrue when such LICENSED PRODUCT is first SOLD.

     4.9  With respect to each LICENSED PRODUCT SOLD by or for a sublicensee,
regardless of whether GALAGEN has caused such sublicensee to pay an amount of
royalties directly to GALAGEN or directly to METAGENICS, royalties payable by
GALAGEN to METAGENICS under this Article IV for such sale shall be deemed to
accrue when the royalties for such sale are billed by the sublicensee to the
customer.

     4.10 It is further understood and agreed by the Parties that no more than
one royalty payment shall be due for any LICENSED PRODUCT subject to royalty
hereunder, regardless of the number of products that the LICENSED PRODUCT is
thereafter incorporated into and regardless of the number of LICENSED PATENT
RIGHTS, or jurisdictions in which the making, having made, making for others,
using, importing from or into, offering for sale and/or sale of such LICENSED
PRODUCT occurs.

                                     ARTICLE V
                       PAYMENT SCHEDULE, REPORTS, AND RECORDS

     5.1  Within sixty (60) days after the end of each calendar quarter in which
royalties accrue under this agreement, GALAGEN and/or any sublicensee, as
appropriate, shall furnish METAGENICS with a written report setting forth the
computation of the royalties


                                          5


payable to METAGENICS during the preceding calendar quarter.  Each report shall
be accompanied by the amount due less any taxes required by a governmental
agency to be withheld with respect to royalties payable to METAGENICS for that
calendar quarter of that year.

     5.2  Royalties shall be paid to METAGENICS in U.S. dollars.

     5.3  GALAGEN shall keep, and shall cause sublicensee(s) to keep, accurate
and complete records in sufficient detail to enable royalties payable to
METAGENICS hereunder to be verified.  GALAGEN shall permit such records to be
inspected once per year upon written notice by METAGENICS for the purpose of
verifying the amount of royalties payable hereunder to METAGENICS.  Such
inspection shall be made during reasonable business hours and shall be performed
by an independent auditor, such as a certified public accountant or firm of
certified public accountants reasonably acceptable to GALAGEN and appointed by
METAGENICS.  METAGENICS shall bear all the costs of retaining the independent
auditor for such inspection unless the independent auditor finds that the
royalties paid to METAGENICS have been deficient by five percent (5 %) or more
when compared to the amount paid to METAGENICS, in which case GALAGEN shall be
obligated to bear all reasonable costs of retaining the independent auditor for
such inspection.  The independent auditors making such inspection shall report
to METAGENICS only the amount of royalties due and payable.  Two (2) years after
furnishing METAGENICS with the written report of Paragraph 5.1, GALAGEN shall
have the right to destroy or discard the records which formed the basis for such
written report, and the written report thereafter shall be presumed to be
correct and accurate.

     5.4  At GALAGEN's option, the reports and records required in this Article
V may be made by GALAGEN, or alternatively, GALAGEN may cause sublicensee(s) to
make the reports and records required in this Article V.

                                     ARTICLE VI
                            INFRINGEMENT AND LITIGATION

     6.1  In the event that METAGENICS or GALAGEN determines that any LICENSED
PATENT RIGHTS are being infringed in the GALAGEN FIELD OF USE by an unlicensed
third party, the knowledgeable party shall immediately notify the other party in
writing of the name and address of the alleged third party infringer, the
alleged acts of infringement, and any available evidence of infringement, and
any factual evidence supporting such claim of infringement.

     6.2  In the event that METAGENICS or GALAGEN determines that any LICENSED
PATENT RIGHTS are being infringed in the GALAGEN FIELD OF USE by an unlicensed
third party, METAGENICS shall have the right to initiate patent infringement
litigation in METAGENICS' name against said alleged third party infringer.
GALAGEN


                                          6


shall have the right, at GALAGEN's option, to join as co-plaintiff in such legal
action for the purpose of enforcing any claim GALAGEN many have and recovering
any damages GALAGEN incurs arising out of the alleged third party infringement.
However, in all circumstances in which METAGENICS elects to initiate legal
action involving the alleged third party infringer, such legal action shall be
under the sole direction of  METAGENICS.  METAGENICS shall bear all expenses,
including attorney's fees, incurred in connection with such legal action, but
GALAGEN agrees to perform all actions as are determined to be reasonably
necessary by METAGENICS legal counsel in the conduct of litigation.  METAGENICS
shall receive any relief obtained by such litigation, including all monetary
awards.  If, at any time during the term of this Agreement, GALAGEN or
METAGENICS shall be unable to uphold the validity of any LICENSED PATENT RIGHTS
against an alleged third party infringer, GALAGEN shall not have a claim for
refund or reimbursement of any previously paid royalty against METAGENICS.

     6.3  Upon becoming aware of any third party infringement or alleged third
party infringement of any of the LICENSED PATENT RIGHTS, METAGENICS shall, as
expeditiously as possible and without undue delay, initiate legal action to stop
the alleged third party infringing activity of any of the LICENSED PATENT
RIGHTS.  If the alleged third party infringing activity does not cease or
METAGENICS does not initiate legal action to stop the alleged third party
infringing activity within sixty (60) days after receiving notification of
alleged third party infringing activity from GALAGEN, GALAGEN shall have the
right to initiate patent infringement litigation in METAGENICS' name against
said alleged third party infringer.  Such litigation will be under the sole
direction of GALAGEN, and at GALAGEN's expense, but METAGENICS agrees to perform
all actions as are determined to be reasonably necessary by GALAGEN's legal
counsel in the conduct of such litigation, including joining in such litigation.
GALAGEN shall receive any relief obtained by such litigation, including all
monetary awards.

     6.4  In the event that any third party shall bring an action against
GALAGEN or its sublicensee(s) for alleged infringement of a third party
intellectual property rights arising out of the manufacture, use or sale of
LICENSED PRODUCT(S) subject to royalty hereunder or the practice of LICENSED
METHOD(S), GALAGEN shall promptly give written notice to METAGENICS reporting
such action.  METAGENICS shall provide such assistance, including the furnishing
of documents and information and the execution of all necessary documents, as
GALAGEN may reasonably require to defend such action.  GALAGEN shall bear the
costs of its own defense and the outcome of any such charge of infringement.
However, during the pendency of such action, if the LICENSED PRODUCT(S) or
LICENSED METHOD(S) would not infringe the third party's intellectual property
rights but for the inclusion of the methods, apparatus, articles of manufacture,
and/or compositions of matter encompassed by one or more claims of the LICENSED
PATENT RIGHTS, then GALAGEN and its sublicensee(s) may reduce any royalty
payment to METAGENICS by one-half for activity in the country where such action
is pending.  In the event that GALAGEN or its sublicensee(s) are obligated to
pay royalties or make further payments to


                                          7


such third party in order to make, have made, make for others, use, import,
offer for sale, sell or otherwise distribute LICENSED PRODUCT(S) or practice
LICENSED METHOD(S) in such country, if the LICENSED PRODUCT(S) or LICENSED
METHOD(S) would not infringe the third party's intellectual property rights but
for the inclusion of the methods, apparatus, articles of manufacture, and/or
compositions of matter encompassed by one or more claims of the LICENSED PATENT
RIGHTS, then such payments shall be creditable by up to one-half of the amount
of royalties payable to METAGENICS with respect to that country.

     6.5  METAGENICS and GALAGEN agree to keep each other fully informed as to
the progress of any such third party infringement action or settlement
discussions pertaining to any such alleged third party infringement initiated in
the sole name or joint names of METAGENICS or GALAGEN.

     6.6  The party bringing and in control of any third party infringement
action or settlement discussions pertaining to any such alleged third party
infringement shall have the right to dispose of such third party infringement
action or such settlement discussions in a reasonable manner which is consistent
with the best interests of METAGENICS and GALAGEN.

                                    ARTICLE VII
                          PATENT EFFORT AND PATENT MARKING

     7.1  The filing, prosecution, and maintenance of LICENSED PATENT RIGHTS and
the cost thereof shall be the responsibility of METAGENICS.  In the event that
METAGENICS elects not to file, prosecute, or maintain any such patents or patent
applications constituting the LICENSED PATENT RIGHTS, METAGENICS shall inform
GALAGEN and give GALAGEN the opportunity to file, prosecute, and/or maintain the
particular patents or patent applications constituting the LICENSED PATENT
RIGHTS.

     7.2  If GALAGEN elects to undertake the responsibility to file, prosecute,
and or maintain at least a portion of one of the two patent families defined as
LICENSED PATENT RIGHTS hereinabove, GALAGEN shall thereafter be entitled to
reduce the royalty payment in the amount of any reasonable expenses, including
attorney's fees, incurred by GALAGEN to do so. GALAGEN shall not be liable to
METAGENICS in respect to any filing, prosecution, maintenance or enforcement of
any such patent or patent applications, or any failure to file for, prosecute,
maintain or enforce any patent or patent applications.

     7.3  GALAGEN agrees to mark the LICENSED PRODUCTS with an appropriate
patent notice and notice of this license, in accordance with the provisions of
35 U.S.C. Section 287(a), as reasonably requested by METAGENICS.


                                          8



                                    ARTICLE VIII
                                  CONFIDENTIALITY

     8.1  Subject to Paragraphs 8.2 and 8.3, GALAGEN and METAGENICS shall
preserve the terms of this Agreement in confidence during the term of this
Agreement and for 2 (two) years thereafter.  Neither party shall have any
obligation to preserve the existence of this Agreement in confidence.

     8.2  [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION***].

     8.3  In the event that GALAGEN enters into negotiations with a third party
for the purpose of obtaining a sublicense from GALAGEN hereunder, GALAGEN shall
have the right, under appropriate confidentiality provisions, to disclose to
such third party the terms and existence of this Agreement.

                                     ARTICLE IX
                                   ASSIGNABILITY

     9.1  This Agreement and the rights and obligations hereunder shall not be
assignable or otherwise transferable, in whole or in part, to third parties by
act or deed of any party hereto or by operation of law, or by order of court,
bankruptcy, receivership or insolvency without the written consent of the other
party; provided, however, that METAGENICS shall have the right to assign its
rights to receive remuneration including royalty under this Agreement to another
without prior written consent of GALAGEN but with written notice to GALAGEN; and
further provided that GALAGEN shall have the right to assign this Agreement
together with its rights and obligations to the successor of the portion of
GALAGEN's business to which LICENSED PATENT RIGHTS related or to a corporation
or entity owning more than 50% of the stock of GALAGEN and entitled to vote for
directors of GALAGEN.

     9.2  Any pretended or attempted assignment or transfer by any party hereto
in violation of this Article shall, ipso facto, cause the rights hereunder of
the offending party to cease.  Otherwise, this Agreement and its rights and
obligations shall be available to and binding upon permitted assigns, legal
representatives, trustees, purchasers, receivers and successors of the parties
hereto as permitted in Paragraph 9.1.

                                     ARTICLE X
                                TERM AND TERMINATION

     10.1 GALAGEN shall have the right to terminate this Agreement in its
entirety or with respect to any or all LICENSED PATENT RIGHTS in any or all
countries, without cause, upon thirty (30) days written notice to METAGENICS;
provided, however, that such


                                          9


termination shall not relieve GALAGEN of any obligations for royalty payments
accrued prior to the effective date of such termination.  GALAGEN shall be
permitted to sell, transfer, or otherwise dispose of for payment any LICENSED
PRODUCT(S) not sold prior to the effective date of such termination; provided
that such sale, transfer or disposal occurs within six (6) months of the
effective date of termination of this Agreement.  During this six (6) month
period, GALAGEN shall continue to provide METAGENICS with the written report of
Paragraph 5.1.

     10.2 METAGENICS shall have the right to terminate this Agreement only in
its entirety and only for the following enumerated reasons:  (i) GALAGEN's
failure to pay the initial fee or for GALAGEN's nonpayment of accrued royalty;
(ii) GALAGEN, or a third party on behalf of GALAGEN, challenges the validity or
enforceability of any of the LICENSED PATENT RIGHTS by bringing a declaratory
judgment action in any United States District Court of competent jurisdiction,
with the exception that METAGENICS shall not have the right to terminate based
upon GALAGEN requesting reexamination of LICENSED PATENT RIGHTS before the
United States Patent Office; and (iii) GALAGEN files a petition in bankruptcy or
insolvency, or upon or after an adjudication that GALAGEN is bankrupt or
insolvent, or upon or after the filing by GALAGEN of any petition or answer
seeking reorganization, readjustment, rearrangement of GALAGEN under any law
relating to bankruptcy or insolvency, or upon or after the appointment of a
receiver for all or any part of the property of GALAGEN or upon or after the
making by GALAGEN of any proceedings for the liquidation or winding-up of
GALAGEN business or for the termination of the GALAGEN corporate charter.
However, prior to terminating this Agreement, METAGENICS shall give GALAGEN
sixty (60) days written notice of METAGENICS intent to terminate and the
reason(s) why, clearly identifying the alleged breach at issue. If GALAGEN cures
such breach, or can reasonably demonstrate that no breach has occurred, within
said sixty (60) day period, then this Agreement shall remain in full force and
effect as if no such notice and/or breach had occurred.

                                     ARTICLE XI
                                       NOTICE

     The parties shall promptly provide written notice of any change of address
to the other party.

                                    ARTICLE XII
                                   FORCE MAJEURE

     Neither of the parties hereto shall be liable to the other party or be
deemed to be in default under this Agreement if its performance is prevented in
whole or in part by a Force Majeure, including but not limited to, strikes,
accidents, rebellions, blockades, riots, storms, fires, explosions, acts of God,
war, sabotage, any law or administrative ruling of any government or political
subdivision thereof having jurisdiction over such part, or any other cause
similar thereto which is beyond the reasonable control of the party whose
performance is prevented in whole or in part; provided, however, that if the
failure or delay in performance by a party persists continuously for a period of
six (6) months or more, the other party may cancel or terminate this Agreement,
in its entirety and not withstanding the provisions of Article X, by giving
thirty (30) days written notice to the non-performing party.  The party whose
performance is prevented by a Force Majeure shall promptly notify the other
party upon becoming aware of a Force Majeure.  The non-performing party agrees
to endeavor to assume its performance in accordance with this Agreement as soon
as practicable.

                                    ARTICLE XIII
                                   GOVERNING LAW

     This Agreement shall be construed in accordance with the laws of the State
of Minnesota.

                                    ARTICLE XIV
                              MISCELLANEOUS PROVISIONS

     14.1 This Agreement contains the complete and entire agreement between the
parties hereto relating to the subject matter hereof, and supersedes any
previous communications, representations, or agreements, whether verbal or
written.

     14.2 No change, addition, waiver, amendment, or modification of any of the
terms of conditions hereof shall be valid or binding on either party unless in
writing and signed by an officer of an authorized representative of both
parties.


                                          11


     14.3 The provisions of this Agreement shall be deemed separable.
Additionally, the parties hereto expressly agree that it is not the intent of
either party to violate any of the state or federal public policies, statutes,
or common laws of the United States.  It is the intent of both parties to make
this Agreement binding only to the extent that it may lawfully be done under
existing state and federal laws of the United States, whichever may be
applicable.  Therefore, if any part of this Agreement is rendered void, invalid,
or unenforceable, or is  judged to be in violation of any state or federal law
of the United States, such rendering or judgment shall not affect the validity
or enforceability of the remainder of this Agreement; provided that if the part
or parts which are void, invalid, or unenforceable as aforesaid shall
substantially impair the value of this whole Agreement to either party, that
party may cancel and terminate this Agreement, in its entirety, by giving thirty
(30) days written notice to the other party.

     14.4 A failure of either party to enforce any of the provisions of this
Agreement of any rights with respect thereto or to exercise any election
provided for herein, shall in no way be considered a waiver of such provisions,
rights, or elections or in any way to influence the validity of this Agreement.
No term or provisions hereof shall be deemed waived and no breach excused or
consented to, unless such waiver or consent shall be in writing and signed by
the party claimed to have waived or consented.  The failure by a party hereto to
enforce any of said provisions, rights, or elections shall not preclude or
prejudice that party from alter enforcing or exercising the same or in any other
provisions, rights, or elections which it may have under this Agreement.  Any
consent by any party to, or waiver of, a breach by the other, whether express or
implied, shall not constitute a consent or waiver of, or excuse for any other
different or subsequent breach.  All remedies herein conferred upon any party
shall be cumulative and no one shall be exclusive of any other remedy conferred
by law or equity.

     14.5 Time is of the essence in the performance of each and every obligation
and covenant imposed by this Agreement.

     14.6 Headings used in this Agreement are for reference purposes only and
shall not be deemed a part of this Agreement.

     14.7 This Agreement may be executed in any number of counterparts, each of
which shall be deemed to be an original, all of which constitute one and the
same agreement.


                                          12



     IN WITNESS WHEREOF, the parties hereto have each caused this Agreement to
be duly executed by their duly authorized representatives.
