     1.   PURCHASE AND SALE; EXCLUSIVITY.

          1.a  PURCHASE AND SALE.  During the term of this Agreement, GalaGen
shall offer and GNP shall purchase from GalaGen Products in bulk which GNP
shall, at its expense, package and label and make into finished product.
GalaGen shall be the exclusive supplier of Products to GNP and GNP shall be the
exclusive manufacturer of products incorporating such Products for GNC and its
affiliates and franchisees and [***CONFIDENTIAL TREATMENT REQUESTED; PORTION
OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***],
provided that nothing herein shall limit GalaGen's right to have Products
manufactured for it.  Without GalaGen's prior written consent, GNP will not
manufacture products incorporating such Products for any parties other than GNC,
its affiliates and franchisees and [***CONFIDENTIAL TREATMENT REQUESTED; PORTION
OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***].  GNC
and its affiliates, and franchisees and [***CONFIDENTIAL TREATMENT REQUESTED;
PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]
will not sell products incorporating such Products outside of the Field,
Territory and Specialized Retail Channel and Mass Market Retail Channel.

          1.b  EXCLUSIVITY.  Subject to Sections 1.c, 1.d, 1.e and 3.a., GNC and
its affiliates and franchisees and [***CONFIDENTIAL TREATMENT REQUESTED; PORTION

          1.c  EXCEPTIONS.  Except as expressly granted in writing by GalaGen,
neither GNP nor GNC, nor any affiliate, franchisee or [***CONFIDENTIAL TREATMENT
REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION***], shall have any rights, exclusive or otherwise, to
[***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE

foregoing, but subject to the Right of First Refusal in Section 5, GalaGen
reserves the right to make, use, and sell Products outside of the Field.  Except

ordered on, and pursuant to the terms and conditions contained in, GNP's
Standard Purchase Order, [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED
FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***].  To the extent
the terms of such Standard Purchase Order are inconsistent with the terms of
this Agreement, this Agreement shall control.

     3.   ORDERS AND FORECASTS.

          3.a  ORDERS AND FORECASTS.  GNP will place Orders for the purchase of
[***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION***] of Products to be delivered by GalaGen
during the calendar year 1999 to maintain the exclusivity rights granted under
Section 1.b.  If GNP does not place Orders for such quantities of Products
during 1999, GNP and GNC shall thereafter have a right to manufacture and sell
products incorporating such Products in the Specialized Retail Channel and Mass
Market Retail Channels on a non-exclusive basis until this Agreement terminates
or expires.  GNP shall place Orders with GalaGen for Products at least twelve
(12) weeks prior to the anticipated shipment date for the Products, provided
that GalaGen may require a longer lead time for Orders of [***CONFIDENTIAL
TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION***] at the time it agrees to make such products available
hereunder.

          3.b  REVIEWS.  The parties shall confer at least quarterly to review
forecasts and to consult on matters relating to the scheduling of manufacturing
and delivery of Products.

     4.   OPTION FOR EXPANDED TERRITORY.

          4.a  OPTION EXERCISE.  In the event GNC desires to sell products
within the Field incorporating one or more Products in an Expanded Territory,
GNC shall have the right within the Option Period to give GalaGen written notice
of the territory outside of the Territory that GNC desires to sell such products
and the Product or Products that GNC desires to incorporate into such products
(unless GalaGen has previously granted rights to a Third Party to sell products
incorporating such Products within such territory after the failure of GNC to
exercise its Right of First Refusal under Section 5).

          4.b  GOOD FAITH NEGOTIATIONS.  Upon receipt of such notice, the
Parties agree to negotiate in good faith the terms upon which GNC will be
granted the right to sell products incorporating such Products in the Expanded
Territory, including whether such rights will be exclusive and, if exclusive,
the minimum outlet/sales requirements required to maintain such exclusivity, the
price of Products (which shall not be less than the price provided for
hereunder), the delivery terms (which shall not require GalaGen to assume any
expenses associated with delivery of Products in the Expanded Territory greater
than GalaGen's costs associated with delivery of the Products within the
Territory) and such other terms as the Parties deem appropriate, provided,
however, that GalaGen may require as a


                                          5
<PAGE>

condition to entering into such good faith negotiations that GNC demonstrate to
GalaGen's reasonable satisfaction that GNC has a commercially reasonable plan to
enable it to sell products incorporating such Products in the Expanded Territory
on a competitive basis.  For purposes hereof, "competitive basis" shall mean
that GNC has a reasonable prospect of being able to penetrate and sell
substantial quantities of such products in the proposed Expanded Territory
within a reasonable period of time.

          4.c  FAILURE TO REACH AGREEMENT.  In the event that, notwithstanding
such good faith negotiations, the Parties are unable to reach agreement as to
the terms upon which GalaGen will make such Products available to GNC for
incorporation into products to be sold in the Expanded Territory within six (6)
months after GNC's notice to GalaGen of its desire to sell such products, either
Party shall be free to terminate such negotiations and, subject to the Right of
First Refusal, if any, of GNC, GalaGen shall be free to sell Products to Third
Parties for incorporation into products that may be sold in the territory with
respect to which GNC desired to be granted Expanded Territory.

     5.   RIGHT OF FIRST REFUSAL.

          5.a  GALAGEN NOTICE.  In the event GalaGen desires to sell Product to
a Third Party within the Option Period who intends to incorporate such Product
into products within the Field to be sold outside of the Territory, GalaGen
shall give GNC written notice of its desire to sell such Product to such Third
Party and the material terms and conditions of such proposed sales (including
the Product or Products proposed to be sold, the territory in which such Product
or Products will be sold, the price and other terms of sale of such Product or
Products and any minimum volume purchase commitments by such Third Party).

          5.b  EXERCISE OF RIGHT.  For a period of sixty (60) days thereafter,
GNC shall have a right of first refusal (the "Right of First Refusal") to enter
into an agreement with GalaGen to purchase such Products on the terms and
conditions that such Third Party is willing to purchase such Products (including
without limitation, price and minimum volume commitments) in the territory that
such Third Party proposes to sell products incorporating such Products or on
terms that, when taken as a whole, are at least as favorable to GalaGen as the
terms specified in the written notice provided to GNC.  GalaGen may as a
condition to the exercise of such Right of First Refusal require that GNC
demonstrate to GalaGen's reasonable satisfaction that GNC has a commercially
reasonable plan to enable it to sell products incorporating such Products in the
territory on a competitive basis.  For purposes of this Section 5, "competitive
basis" shall mean that GNC has a reasonable prospect of being able to sell such
products in the proposed territory on a basis reasonably comparable to the Third
Party's ability to market such products.

          5.c  FAILURE TO EXERCISE.  Failure to exercise such Right of First
Refusal within such sixty (60) day period, shall be deemed a waiver by GNC of
its Right of First Refusal.  In the event GNC does not exercise its Right of
First Refusal, GalaGen shall thereafter be free to sell such Products to such
Third Party in accordance with the material terms and conditions of such
proposed sales or on terms that, when taken as a whole, are at



                                          6
<PAGE>

least as favorable to GalaGen as the terms specified in the written notice
provided to GNC.  Moreover, once GalaGen has entered into an agreement to sell
Products to a Third Party outside of the Territory in accordance herewith, GNC
shall no longer have any Right of First Refusal with respect to the right to
sell products incorporating the Product or Products which GalaGen has agreed to
sell to such Third Party in the territory that GalaGen has agreed to permit such
Third Party to sell products incorporating the Product or Products, regardless
of whether such Third Party continues to have a right to sell such products in
such territory or in such Individual Channel or Channels.

     6.   TERM.  The Term of this Agreement shall be for a period of
[***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION***] years from the date hereof unless earlier
terminated in accordance with Section 20.  After the Term, this Agreement will
renew on a yearly basis unless GNC gives GalaGen at least six (6) months prior
written notice that it intends not to extend this Agreement or, if all of the
Products covered by this Agreement are being sold on a non-exclusive basis,
GalaGen gives GNC at least six (6) months prior written notice that it is
terminating this Agreement.  In addition, in the event rights to the Specialized
Retail Channel or a Mass Market Retail Channel have become non-exclusive,
GalaGen shall have the right after the Term upon at least six (6) months prior
written notice, to terminate GNC's non-exclusive right to sell products
incorporating Product into the non-exclusive channel or channels  Renewal will
be on an exclusive basis in the Specialized Retail Channel if the Outlet/Sales
Requirements for Specialized Retail have been met for the year preceding such
renewal, to the extent that such Rights are exclusive at the time of such
renewal.  Renewal will be on an exclusive basis in the applicable Mass Market
Retail Channel if the Outlet/Sales Requirements for Mass Market have been met
for the year preceding such renewal, to the extent that such Rights are
exclusive at the time of such renewal.  Minimum Outlet/Sales Requirements for
Specialized Retail and/or Minimum Outlet/Sales Requirements for Mass Market for
the renewal period will be mutually negotiated, provided that if the parties
cannot agree upon such Minimum Outlet/Sales Requirements prior to expiration of
the then current Term, GalaGen shall allow GNC to renew GNC's rights in the
Specialized Retail Channel and/or the Mass Market Retail Channel, as the case
may be, on a non-exclusive basis for an additional one (1) year period.

investigation and pay all of GNC's reasonable out-of-pocket costs and expenses

each of its and their respective employees, officers, directors and agents
(each, a "GalaGen Indemnified Party") from and against any and all liability,
loss, damage, cost and expense (including reasonable attorneys' fees)
(collectively, a "Liability"), which the GalaGen Indemnified Party may incur,
suffer or be required to pay resulting from or arising in connection with (i)
the breach by GNC or GNP or their affiliates or franchisees [***CONFIDENTIAL
TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION***] of any covenant, representation or warranty contained in
this Agreement, (ii) willful misconduct or negligent acts or omissions of GNC or
GNP, their respective affiliates, franchisees [***CONFIDENTIAL TREATMENT
REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
COMMISSION***] or any of their employees, officers, directors or agents, or
(iii) the successful enforcement by a GalaGen Indemnified Party of its rights
under this Section 10.a.  Notwithstanding the foregoing, GNC/GNP shall have no
obligation under this Agreement to indemnify, defend or hold harmless any
GalaGen Indemnified Party with respect to claims, demands, costs or judgments
which result from willful misconduct or negligent acts or omissions of GalaGen,
its affiliates, or any of their respective employees, officers, directors or
agents.

          10.b INDEMNIFICATION BY GALAGEN.  GalaGen shall indemnify, defend and
hold harmless GNC, GNP and their franchisees, affiliates [***CONFIDENTIAL
TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND
EXCHANGE COMMISSION***], and each of their respective employees, officers,
directors and agents (each, a "GNC/GNP Indemnified Party") from and against any
Liability, which the GNC/GNP Indemnified Party may incur, suffer or be required
to pay resulting from or arising in connection with (i) the breach by GalaGen of
any covenant, representation or warranty contained in this Agreement; (ii)
willful misconduct or negligent acts or omissions of GalaGen, its affiliates, or

GNP's or GNC's breach of representations or warranties herein or GNP's or GNC's
negligence or willful misconduct) or (iv) the successful enforcement by a
GNC/GNP Indemnified Party of its rights under this Section 10.b.
Notwithstanding the foregoing, GalaGen shall have no obligation under this
Agreement to indemnify, defend, or hold harmless any GNC/GNP Indemnified Party
with respect to claims, demands, costs or judgments which result from willful
misconduct or negligent acts or omissions of GNC/GNP, their affiliates, or any
of their respective employees, officers, directors or agents.

          10.c CONDITIONS TO INDEMNIFICATION.  The obligations of the
Indemnifying Party under Sections 10.a and 10.b are conditioned upon the
delivery of written notice to the


                                          9
<PAGE>

Indemnifying Party of any potential Liability promptly after the Indemnified
Party becomes aware of such potential Liability. The Indemnifying Party shall
have the right to assume the defense of any suit or claim related to the
Liability if it has assumed responsibility for the suit or claim in writing;
however, if in the reasonable judgment of the Indemnified Party, such suit or
claim involves an issue or matter which could have a materially adverse effect
on the business operations or assets of the Indemnified Party, the Indemnified
Party may waive its rights to indemnity under this Agreement and control the
defense or settlement thereof, but in no event shall any such waiver be
construed as a waiver of any future indemnification rights such Party may have
at law or in equity. If the Indemnifying Party defends such suit or claim, the
Indemnified Party may participate in (but not control) the defense thereof at
its sole cost and expense.

          10.d SETTLEMENTS.  Neither Party may settle a claim or action related
to a Liability without the consent of the other Party, if such settlement would
impose any monetary obligation on the other Party or require the other Party to
submit to an injunction or otherwise limit the other Party's rights under this
Agreement. Any payment made by a Party to settle any such claim or action shall
be at its own cost and expense.

     11.  INSURANCE.  GalaGen shall maintain during the term of this Agreement a
policy of general liability insurance, including products liability insurance,
business interruption insurance and contractual insurance, with limits of no
less than two million dollars, from a reliable insurance carrier acceptable to
GNC, which acceptance may not be unreasonably withheld. GalaGen shall name GNC
and GNP as additional insured under such coverage. GalaGen shall keep and
maintain its general liability insurance in effect during the term of this
Agreement. GalaGen shall notify GNC immediately upon cancellation of, or any
reduction in, its general liability insurance coverage, and cancellation or
reduction of such general liability coverage shall constitute a material breach
of this Agreement, provided however, that GalaGen shall be entitled to cure such
breach within forty-five (45) days provided that, during the forty-five (45) day
cure period, the insurance coverage is maintained, reinstated or re-established
without a lapse.  GNC shall name GalaGen as additional insured under the general
liability insurance, including products liability insurance, maintained by GNC.

Committee.  If possible, the meetings shall be held in person, or where
appropriate by video or telephone conference.  When held in person, the location
of such meetings shall alternate between GalaGen's facilities and GNC's
facilities.  Each Party shall be responsible for the expenses incurred by its
representatives in attending such meetings.

     13.  MARKETING, TECHNICAL AND CLINICAL DEVELOPMENT SUPPORT.  GalaGen will
provide research and development for the development of commercially attractive
products approved by the Joint Development Committee, subject to agreement on
funding for such research and development.  Funding for such research and
development will be established on a case-by-case basis. GalaGen will support
GNC's marketing of products containing Products with up-to-date technical
information, content for consumer educational material, and design of
appropriate clinical testing protocols, to be conducted and funded as negotiated
by GNC and GalaGen for specific needs.  GNC and GalaGen agree to use good faith
efforts to promote GNC products containing Products through publications or
other media outlets. GalaGen agrees to allow GNC to use all information relating
to Products in GNC's labeling and advertisement of products containing Products.
GNC and GalaGen agree to review the feasibility of implementing research studies
on GNC products containing Products either alone or in combination with other
ingredients.

     14.  TRADEMARKS.  GalaGen hereby grants to GNC and GNP the Trademark
License for the purpose specified herein.  GalaGen shall provide GNC and GNP
with camera ready artwork of the GalaGen trademark Proventra-TM- and reasonable
guidelines (the "Guidelines") governing the use of the GalaGen Trademark (such
as size, color and placement).  The Guidelines will reflect that the GalaGen
Trademark is to be displayed in such a manner so as to convey the impression
that the finished GNC products include Products.  GNC and GNP shall not permit
any agent or subdistributor to use the GalaGen Trademark without GalaGen's prior
written approval;  use or permit any agent to use any trademark or product


                                          11
<PAGE>

names confusingly similar to Products; or use or permit any agent to use the
GalaGen Trademark on any objects, other than those containing Products.  GNC and
GNP agree to notify GalaGen in writing of any claim or action for infringement
or unfair competition relating to the GalaGen Trademark, which is threatened or
brought against GNC/GNP by a third party and of any conflicting uses of,
application or registrations for, or acts of infringement or unfair competition
involving the GalaGen Trademark promptly after GNC/GNP learns of any such
matter.  GNC/GNP shall furnish all records, documents, specimens and testimony
relating to such claim or action to GalaGen (at GalaGen's expense) as GalaGen
may request and shall otherwise cooperate with GalaGen in any such claim or
action.

     15.  TESTING AND QUALITY CONTROL.

          15.a SPECIFICATIONS; INSPECTION.  All Products delivered to GNP must
meet the specifications in SCHEDULE 2 (or as otherwise  agreed to by the parties
and incorporated herein, the "Release Specifications") and contain a certificate
of analysis.  Prior to the initial shipment of Products to GNP, GalaGen agrees
to provide GNP with complete specifications. Further, GalaGen agrees to provide
GNP with analytical test methodology and analytical and technical information on
Products for quality control purposes.  GNP shall have the right to inspect
during reasonable business hours GalaGen's production facilities used in
connection with the manufacture of Products.  GalaGen agrees to grant GNP
reasonable access to the reports, records and other documents relating to the
manufacture of Products, including copies of all inspection and other reports by
federal, state and local regulatory agencies.  GalaGen shall have the right to
inspect GNP's production facilities during reasonable business hours in
connection with production of products incorporating Products.

          15.b STABILITY TESTING.  Stability testing consistent with GalaGen's
existing program for stability testing will be undertaken at GalaGen's expense
for Products.  Any stability testing requested by GNC beyond GalaGen's existing
program will be funded by GNC.  GalaGen will bill GNC at cost for additional
stability testing that may be required for combination formula products
developed jointly by the two companies.

     16.  INVENTIONS.

          16.a OWNERSHIP.  GalaGen shall own all Inventions made solely by its
employees and agents, and all patent applications and patents claiming such
Inventions.  GNC or GNP, as the case may be, shall own all Inventions made
solely by its employees and agents and all patent applications and patents
claiming such Inventions.  All Inventions made jointly by employees or agents of
GalaGen and employees or agents of GNC and/or GNP ("Joint Inventions") shall be
owned jointly by GalaGen and GNC and/or GNP.  All determinations of inventorship
shall be made in accordance with U.S. law.

          16.b JOINT PATENT APPLICATIONS.  Each Party shall have the right to
identify any Joint Invention that may be patentable.  The Parties shall jointly
take all reasonable steps to seek, maintain and/or prosecute patent applications
for such Joint Inventions and all


                                          12
<PAGE>

patents relating thereto shall be registered in the names of GalaGen and GNC
and/or GNP, as the case may be, while all costs incurred in connection with
seeking, maintaining and/or prosecuting the patent protection shall be borne
equally by GalaGen and GNC (and/or GNP, as the case may be) except as hereafter
provided.  Should either GalaGen or GNC (or GNP, as the case may be) not wish to
pay the costs relating to any patent application filed or to be filed pursuant
to this Section 16.b, then the Party wishing not to pursue such patent
application shall allow the other Party to continue with such application in the
name of the Parties jointly.  In such case, the Party seeking, maintaining
and/or prosecuting the patent protections shall bear all costs incurred in
connection therewith, the non-pursuing Party shall provide reasonable
nonpecuniary assistance and the non-pursuing Party shall grant to the pursuing
Party a worldwide, exclusive, even as to itself, perpetual royalty-free license
to use and/or exploit the technology subject to the patent application.  Such
license will be with right to sublicense.

          16.c USE OF JOINT INVENTIONS.  Subject to Section 16.b, either Party
may use Joint Inventions, or grant licenses to Third Parties thereunder, subject
to the following conditions:

     (i)  To the extent such Joint Invention relates to the manufacture of a
          bovine colostrum-based ingredient (which for purposes hereof shall
          include, without limitation, the preparation of vaccine, vaccination
          of animals, collection and processing of colostrum into bovine
          immunoglobulin concentrates, and the testing, packaging and storage of
          such ingredient), GalaGen shall have the sole right to use and exploit
          such Invention in the manufacture of such ingredients.

     17.  NOTICES.  All demands, notices, and other communications to be given
hereunder, if any, shall be in writing and shall be sufficient for all purposes
if personally delivered, sent by facsimile, sent by nationally-recognized
courier service, or if sent by registered or certified United States mail,
return receipt requested, postage prepaid, and addressed to the respective party
at the postal address set forth herein or to such other address or addresses as
such Party may hereafter designate in writing to the other Party as herein
provided.  The present addresses of the Parties hereto are set forth above. If
personally delivered, notice under this Agreement shall be deemed to have been
given and received and shall be effective when personally delivered.  Notice by
facsimile and nationally-recognized courier service shall be deemed to have been
given when received.  Notice by mail shall be deemed effective and complete upon
deposit in the United States mail.

     18.  ENTIRE AGREEMENT, AUTHORITY AND GOVERNING LAW.  This Agreement, which
includes the Exhibits and Schedules hereto, contains the entire agreement of the
parties relating to its subject matter and the parties agree that this Agreement
supersedes all prior written or oral agreements, representations, and warranties
relating to its subject matter.  No modification of this Agreement shall be
valid unless made in writing and signed by the Parties.  Each Party represents
to the other Party that it has the full right and authority to enter into this
Agreement and to perform the obligations set forth herein of such Party.  This
Agreement shall be enforced in accordance with the laws of the State of
Minnesota and shall


                                          13
<PAGE>

be construed in accordance therewith.

     19.  FORCE MAJEURE.  No Party shall be responsible or liable for any loss,
damage, detention or delay caused by fire, strike, insurrection or riot,
railroad, marine or air embargoes, lockout, accident, or any other cause which
is unavoidable or beyond its reasonable control, provided that performance
shall, as soon as practicable, recommence upon the cessation of such unavoidable
event.

     20.  TERMINATION.  In the event of a material breach by either Party of the
terms and conditions of this Agreement (a "Default"), the nonbreaching party may
give the other party written notice of such Default.  In the event the Default
is remedied within forty-five (45) days following such notice, the notice shall
be null and void.  If such Default is not remedied within such forty-five (45)
day period, the nonbreaching Party may terminate this Agreement upon the
expiration of such remedy period.  The rights of termination referred to in this
Agreement are not intended to be exclusive and are in addition to any other
rights available to the Parties in law or in equity.

     Either Party may terminate this Agreement if there shall be commenced by or
against the other Party any dissolution or any bankruptcy, insolvency or similar
proceedings, or the other Party makes an assignment for the benefit of creditors
or a receiver or trustee shall be appointed for all or substantially all of the
other Party's assets.

     21.  CONFIDENTIALITY.

          21.a CONFIDENTIALITY OBLIGATION.  During the term of this Agreement
and after its expiration or termination, each Party agrees to keep confidential,
and to use all commercially reasonable efforts to require its respective
officers, directors, employees and agents to keep confidential all proprietary
information of the other Party, including without limitation any information
specifically identified by either Party prior to disclosure as being
confidential information, plans and data concerning products, marketing, sales,
customers, and technical or business matters.  Disclosure of such confidential
information shall be made by either Party only to those of its employees and
agents who need to know such information in order to carry on the purposes of
this Agreement, and who have agreed to abide by confidentiality requirements at
least as restrictive as those set forth herein.

          21.b EXCEPTIONS.  These obligations shall not apply to information
that is known at the time of its receipt by the receiving Party and not through
prior disclosure by the disclosing Party, as documented by business records; is
developed by the receiving Party independently of the information received from
the disclosing Party and such independent development can be documented by the
receiving Party; is at the time of disclosure or thereafter becomes published or
otherwise part of the public domain without a breach of this Agreement by the
receiving Party; or is required by law, regulation, rule, act or order of any
governmental authority or agency to be disclosed by a Party, provided that such
Party gives the other Party a reasonable opportunity to seek a protective order
or other similar order and the disclosing Party discloses to the requesting
entity only the minimum confidential information required to be disclosed in
order to comply with the request.


                                          14
<PAGE>

          21.c OTHER PRECAUTIONS.  Other precautions for protecting proprietary
and confidential information of the Parties that are agreed to in writing by the
Parties shall supplement this section and shall not be substituted for the
restrictions herein provided.

     22.  PUBLICITY.  The Parties agree not to disclose, either directly or
indirectly, the existence of (i) this Agreement with any Third Party or the
media without the consent of the other Party and (ii) any differences between
the Parties, or any disputes that have risen to the level of a matter in Direct
Negotiation or litigation, or any facts, directly or indirectly related to such
matters, to any Third Party or the media, provided, however, that either Party
may disclose the terms of this Agreement to the extent required to enforce this
Agreement or to comply with applicable laws, including without limitation the
rules and regulations promulgated by the Securities and Exchange Commission and
the Party intending to disclose the terms of this Agreement shall provide the
nondisclosing Party an opportunity to review and comment on the intended
disclosure which is reasonable under the circumstances.  Notwithstanding any
other provision of this Agreement, either Party may disclose the terms of this
Agreement to lenders, investment bankers and other financial institutions for
purposes of financing operations of such Party, subject to obtaining a
confidentiality agreement from such financial institution.

     23.  WAIVER, ASSIGNMENT AND SEVERABILITY.  The waiver of a breach of any
term or condition of this Agreement shall not be deemed to constitute the waiver
of any further breach of such term or condition or the waiver of any other term
or condition of this Agreement. Neither Party shall have the right to assign
this Agreement or any right or interest herein in part or in whole without the
prior written consent of the other Party.

     24.  NO PARTNERSHIP.  Nothing in this Agreement shall be construed to give
rise to a relationship between the Parties hereto as a joint venture or
partnership or other relationship than that of independent contractors.

     25.  MANDATORY DIRECT NEGOTIATION OF DISPUTES.  The Parties hope there will
be no disputes arising out of their business relationship.  However, if a claim
of breach, nonperformance, nonpayment, repudiation or other dispute should arise
related to or connected with this Agreement or any transactions between the
Parties (a "Dispute"), then the Parties agree to attempt to informally resolve
the Dispute by Direct Negotiation before initiating any claim related to such
Dispute in a court of competent jurisdiction.  "Direct Negotiation," as used
herein, shall mean a meeting (held either by telephone or in-person) between
senior business principals designated by each Party who have full authority to
address and resolve the Dispute.  Direct Negotiation is a prerequisite to
litigation involving all Disputes between the Parties except that either Party
may proceed directly to a court of law or equity to seek emergency injunctive
relief or remedy any safety concerns.  To initiate Direct Negotiation, the
complaining Party shall make a written demand on the other by certified mail to
the primary address of record and identify therein the nature of the Dispute and
all issues which, in the opinion of the complaining Party, need to be resolved
to restore the business relationship.  Any Disputes not expressly raised in this
notice for Direct Negotiation are waived with respect to subsequent litigation
unless such Disputes are


                                          15
<PAGE>

subsequently submitted to Direct Negotiation.  The Direct Negotiation shall take
place during the thirty (30) days following the date of receipt of the demand,
at a time and place agreed to by the business principals, and each Party agrees
to negotiate in good faith in an attempt to resolve the Dispute.  The Parties
agree to exchange relevant information and cooperate in good faith to resolve
the Dispute under this provision and to that end, the non-complaining Party
shall issue a statement which addresses the complaining Party's identified
Dispute and/or raises additional issues for resolution prior to the Direct
Negotiation.  If the Dispute remains unresolved following Direct Negotiation or
if the Direct Negotiation is not completed within the specified 30-day time
period, then the moving party may issue a fifteen (15) day written notice, and
if the Direct Negotiation does not resolve the Dispute or is not completed
within the specified 15-day period, then the aggrieved Parties are released to
file suit if they choose to further pursue the Dispute.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the date
first hereinabove set forth.
