            Covenants Between Execution and Closing and Post-Closing

                  6.1 Access to Records.

                      (a) From and after the date of this Agreement until the
Closing Date, upon reasonable advance notice, InCon will give Humko and its
counsel and representatives reasonable access during normal business hours to
the premises of InCon's business and the personnel of InCon related thereto;
furnish to Humko and its representatives such documents, financial information
and information with respect to InCon's business and the Technology as Humko may
from time to time reasonably request; subject, however, to any third party
limitations on confidentiality or disclosure that may restrict InCon from
providing such access.

                      (b) InCon and Humko recognize that each of them will need
access, from time to time, after the Closing, to certain accounting and Tax
records and information held by InCon to the extent such records and information
pertain to events occurring on or prior to the Closing; therefore, InCon agrees
(i) to properly retain and maintain such records for a period of seven (7) years
from the date the Tax Returns for the year in which the Closing occurs are filed
or until the expiration of the statute of limitations with respect to such year,
whichever is later, and (ii) allow Humko and its agents and representatives at
times and dates mutually acceptable to the InCon and Humko, to inspect, review
and make copies of such records as such other party may deem necessary or
appropriate from time to time, such activities to be conducted during normal

                  6.2 Conduct of Business Prior to Closing. From the date
hereof to the Closing Date, InCon shall carry on its business in substantially
the same manner as heretofore conducted, and not introduce any materially
different method of management, operation or accounting with respect to its
business.

in this Section 6.3, neither InCon nor Bionutrics is aware of any filings that

                   Covenants of the Parties After the Closing

                  7.1 Indemnification Regarding Pre-existing Liabilities. InCon
and Bionutrics (individually, an "Indemnitor" and collectively, the
"Indemnitors") each jointly and severally agrees to indemnify, hold harmless and
defend each of Humko and the Company and each of their officers, partners,
directors, owners, and Affiliates and their respective successors and assigns,
from and against any and all demands, claims, suits and causes of action and any
and all liability, costs, expenses, settlements, and judgments incurred in
connection therewith (including, without limitation, court costs and attorney's
fees, charges, disbursements and advances), whether arising in equity, at common
law, or by statute, or under the Law of contracts, torts (including, without
limitation, negligence and strict liability without regard to fault), of every
kind or character, arising in favor of or brought by any of InCon's employees,
agents, subcontractors, or representatives, or by any Governmental Authority or
any other third party, based upon, in connection with, relating to or arising
out of (i) any Indemnitor's actions or inactions under this Agreement, (ii)
violation of any Laws by any Indemnitor including, without limitation, any
Environmental Laws and any violation thereof by InCon in connection with its
business or its operation of the Facility, (iii) caused by any
misrepresentation, breach of warranty or failure to fulfill any covenant or
agreement of any Indemnitor contained herein, (iv) arising out of or resulting
from the failure to comply with any applicable bulk sales act, (v) any act or
failure to act by any Indemnitor or any of its Affiliates that occurred before
the Effective Date relating to or arising out of the operation of any
Indemnitor's business, the Intellectual Property Rights, the Proprietary
Information or the Technology, or the ownership or use prior to the Effective
Date of any of the Assets comprising InCon's business or which are otherwise
being transferred to the Company pursuant to the provisions of this Agreement,
or (vi) any obligation or liability (whether absolute, accrued, contingent or
otherwise) relating to any Indemnitor's business, the Intellectual Property
Rights, the Proprietary Information or the Technology which arose prior to the
Effective Date and which is not expressly assumed by the Company (herein all
matters referred to in clauses (i) through (vi) being collectively called
"Claims and Expenses"). Without limiting the generality of the foregoing, each
Indemnitor's indemnity under this Section 7.1 shall extend to any and all Claims
and Expenses arising out of or based upon the requirements of Environmental Laws
or Governmental Authorities in connection with the ownership or operation by
InCon or any of its Affiliates of any facilities associated with InCon's
business or the Technology prior to the Closing Date (herein collectively called
the "Environmental Claims and Expenses"). Notwithstanding anything to the
contrary contained in this Agreement, Bionutrics' liability for Claims and
Expenses under this Section 7.1 shall be limited to the sum of US $3,000,000,
and Bionutrics shall not be liable for any Claims and Expenses brought by Humko
at any time (i) in the case of Environmental Claims and Expenses, five (5) years
after the Closing Date, and (ii) in the case of all other Claims and Expenses,
three (3) years after the Closing Date. The obligations of InCon under this
Section 7.1 are secured by the security interest granted to Humko under the
terms of Section 4.4 of the Members Agreement. In addition, if InCon fails to
pay to the Company or Humko any Claims and Expenses that the Company is required
to pay, Humko is entitled to exercise its right to the Conversion, as defined in
Section 4.5(d) of the Members Agreement, in addition to all other rights under
this Agreement, the Members Agreement or at law or in equity. All past due

                                       26
<PAGE>   33
amounts owed by InCon and Bionutrics with respect to any Environmental Claims
and Expenses that are required to be paid by Humko or the Company, shall bear
interest from the date due until paid at the annual rate equal to the lesser of
(i) the maximum lawful rate permitted by applicable law or (ii) the Agreed
Interest Rate, as defined in the Members Agreement, plus eight percent (8%).
However, in no event shall Humko or the Company be entitled to any interest on
any such amounts in excess of the maximum amount of interest that may be
charged, collected or received by Humko or the Company under applicable law.

                  7.2 Confidentiality.

                      (a) If either party or its Affiliates discloses to the
other party or its Affiliates or, if permitted, to the Company any information
that the disclosing entity considers to be confidential (referred to herein as
the "Confidential Information") relating to or within the Scope of Business, the
receiving party shall, and shall cause its Affiliates to, hold such Confidential
Information in confidence and shall not use such Confidential Information except
for the benefit of the Company in accordance with this Section.

                      (b) The Confidential Information may be disclosed in
documentary form or by physical sample or the Confidential Information may be
disclosed orally or visually. If in documentary form, the Confidential
Information shall be marked as "Confidential Information." If the disclosure is
by physical sample, oral communication or visual observation, the Confidential
Information shall be held in confidence if it is identified to the recipient in
writing as being confidential.

                      (c) Each party agrees to hold and to cause its Affiliates
to hold Confidential Information received from the other party or its Affiliates
in confidence and not to disclose it to third parties without the prior written
permission of the party from which the Confidential Information was received.
Further, each party agrees that neither it nor its Affiliates will copy or use
Confidential Information of the other party or its Affiliates for any purpose
except as otherwise permitted under the provisions of this Agreement or a
Related Agreement.

                      (d) Each party shall take, and shall cause its Affiliates
to take, such precautions as are reasonably necessary to prevent disclosure of
Confidential Information to third parties. Confidential Information may be
disclosed under the same or more restrictive terms of this Agreement as to
confidentiality and non-use to: Affiliates; third parties to the extent
reasonably necessary in order to perform activities contemplated herein; and
Governmental Authorities to the extent required by applicable Law.

                      (e) The parties and their Affiliates shall take all
reasonable measures to ensure that their employees and management who shall be
given access to Confidential Information shall abide by the obligations set
forth in this Section.

                      (f) Notwithstanding the other provisions of this Section,
Confidential Information shall not include, and no restrictions on use or
disclosure shall apply to, any information:

                                       27
<PAGE>   34
                           (i) which was in the receiving party's possession
prior to its first receipt of the same, directly or indirectly, from the
disclosing party;

                           (ii) which is now, or hereafter becomes, through no
act or failure to act on the receiving party's part, generally known on a
non-confidential basis or as part of the public domain;

                           (iii) which corresponds in substance to information
heretofore or hereafter lawfully obtained by the receiving party from a third
party and the receiving party is without an existing restriction on the
disclosure thereof; or

                           (iv) which can be shown to be independently developed
by employees, agents or contractors of the receiving party who did not have
access to Confidential Information of the disclosing party;

                  provided, however, that the occurrence of (i), (ii), (iii) or
(iv) above shall not be construed to grant any rights, express or implied, under
any patents. Confidential Information shall not be deemed to be within one of
the foregoing exceptions if it is merely embraced by more general information
available on a non-confidential basis or in the receiving party's possession. In
addition, any combination of features shall not be deemed to be within the
foregoing exceptions unless the combination itself and its principle of
operation are embraced by corresponding information which is within one of the
exceptions.

                           (g) The secrecy and non-use obligations set forth in
this Section shall continue in force for a period of five (5) years from receipt
of such Confidential Information or such longer period as may be imposed under
third-party agreements with respect to information subject to such agreements,
irrespective of any termination or assignment of a party's or an Affiliate's
interest under this Agreement or any Related Agreement. If Confidential
Information is, under third-party agreements, subject to secrecy and non-use
obligations of duration greater than five (5) years from its receipt hereunder,
the disclosing party shall so inform the recipient party before making such
disclosure and, if the recipient party agrees to such longer term obligation of
secrecy and non-use, such disclosures shall be made. If the recipient party
refuses to assume such longer term obligation, the recipient party shall have no
right to obtain any Confidential Information that is subject to such longer term
obligation.

                           (h) The confidentiality provisions contained in any
Related Agreement shall supersede and replace the provisions of this Section 7.2
to the extent that the provisions in the Related Agreement are more specific or
impose obligations that are more stringent than the provisions in this Section
7.2.

         7.3 Budget. Within thirty (30) days after the Closing, Humko and InCon
shall agree on the annual budget for the Company. Until such budget has been
approved, the Company shall be operated in accordance with the Members Agreement
and the only amounts that may be utilized by the Company to satisfy its
obligations shall be the amounts contributed by InCon and Humko to the Company
as working capital, subject to the restrictions imposed by the Members
Agreement.

         7.4 Guaranteed Payment to Humko. Humko has entered into this Agreement
and is making the cash investment covered by this Agreement, based in part on
the belief that the Company will achieve a certain level of profitability.
Although such profitability can never be assured, InCon and Bionutrics, in order
to induce Humko to enter into this Agreement and make the cash investment
covered by this Agreement hereby agree as follows:

(a) If EBITDA for the period commencing one (1) calendar year after the date
hereof and ending on the date that is two (2) calendar years after the date
hereof, is less than US $1,500,000, then InCon and Bionutrics shall jointly and
severally be liable to pay to Humko an amount equal to two hundred percent
(200%) of the difference between US $1,500,000 and the actual amount of EBITDA
for such period; provided, however, that the maximum amount payable by InCon and
Bionutrics under this Section 7.4(a) shall not exceed US $600,000. InCon and
Bionutrics will pay Humko all amounts which are required to be paid under this
Section 7.4(a) on or before November 30, 2001.

(b) The covenant to pay to Humko the amounts set forth in Section 7.4(a) above
is absolute and unconditional and is secured by the security interest granted to
Humko under the terms of Section 4.4 of the Members Agreement. In addition, if
InCon and Bionutrics fail to pay all of such amounts to Humko in a timely
manner, Humko is entitled to exercise its right to the Conversion, as defined in
Section 4.5(d) of the Members Agreement, in addition to all other rights under
this Agreement, the Members Agreement or at law or in equity.

(c) All past due amounts owed by InCon and Bionutrics with respect to such US
$600,000, shall bear interest from the date due until paid at the annual rate
equal to the lesser of (i) the maximum lawful rate permitted by applicable law
or (ii) the Agreed Interest Rate, as defined in the Members Agreement, plus
eight percent (8%). However, in no event shall Humko be entitled to any interest
on any such amounts in excess of the maximum amount of interest that may be
charged, collected or received by Humko under applicable law.

         7.5 Restrictions Relating to Certain Products and Materials. Until
April 8, 2001, neither Bionutrics, InCon nor any Affiliate, assignee or agent of
Bionutrics or InCon shall (i) participate in any Competitive Activity within the
Territory, (ii) engage directly or indirectly in any Competitive Activity within
the Territory; or (iii) engage directly or indirectly in the business of
[*]within the Territory.

         7.6 Adjustment Relating to Receivables and Payables Only. If the
aggregate amount of

                                       29
<PAGE>   36
the accounts receivable listed on Schedule 4.30 do not exceed the aggregate
amount of the accounts payable listed on Schedule 4.29 by an amount equal to US
$275,000 on the Closing Date, then the following shall be applicable:

                  (a) InCon shall pay to the Company on the date hereof an
amount equal to the difference between US $275,000 and the difference between
such accounts receivable and such accounts payable. By example and not by way of
limitation, if such accounts payable equal US $400,000 and such accounts
receivable equal US $100,000, then the amount to be delivered to the Company
shall be equal to US $575,000.

                  (b) Such amount shall not constitute a capital contribution
but shall constitute payment to the Company for amounts to be paid on the
applicable accounts payable.

         8.3 Mutual Conditions. The respective obligations of Humko, InCon and
Bionutrics to consummate the transactions provided for by this Agreement are
subject, in the discretion of Humko, InCon and Bionutrics, respectively, to each
the following conditions, unless waived in writing by all parties:

                  (a) All consents and approvals of third parties (including,
without limitation, all Governmental Authorities) required to be received by or
on the part of the Company, InCon, Bionutrics, Humko or any of their respective
Affiliates for the consummation of the transactions contemplated by this
Agreement (other than any such consent or approval which is designated herein or
in a Related Agreement as not being required to be received on or prior to the
Closing Date) shall have been obtained.

                  (b) No suit, action or proceeding, or governmental
investigation or inquiry against or concerning, directly or indirectly, the
Company, InCon, Bionutrics or Humko, or any of their respective Affiliates or
any of the properties of any of them, or the transactions contemplated hereby,
shall have been instituted or threatened, nor shall any basis therefore have
arisen, that might result in any order or judgment of any court or other
Governmental Authority which in the opinion of InCon, Bionutrics or Humko, as
the case may be, is of such significance or materiality and of such a nature as
to render it inadvisable for such party to consummate the transactions
contemplated by this Agreement.

                  (c) The parties shall have agreed on a preliminary business
plan for the Company in such detail as may be reasonably requested by either
party covering the period of time from the Closing Date until one (1) year
thereafter.

         8.4 Waiver of Conditions to Closing. If any condition precedent to
Humko's obligations hereunder is not satisfied in Humko's sole discretion by the
Closing Date or if any condition precedent to InCon's obligations hereunder is
not satisfied in InCon's or Bionutrics' sole discretion by the Closing Date,
then Humko, InCon or Bionutrics, as the case may be, may, nevertheless, at its
option, proceed with the Closing, in which event it shall be deemed to have
waived such condition precedent.

                            Termination of Agreement

         9.1 Termination of this Agreement Prior to the Closing Date.

                  (a) In the event of a material default by one party in the
performance of its obligations hereunder prior to the Closing, the other party
shall have the right to give notice of default, and if such default is not cured
within thirty (30) days after such notice, the other party may terminate this
Agreement by notice to the defaulting party. Whether or not this Agreement is so
terminated, each party shall have the right to pursue any and all remedies
available to it under Law or in equity against the other party for default of
any obligation of the other party hereunder.

written notice, be terminated by mutual consent of InCon, Bionutrics and Humko.

                  (c) In the event this Agreement is terminated pursuant to
Section 9.1(a) or 9.1(b), the obligations of the parties hereunder shall
terminate on the date of such termination, except as may be expressly provided
herein, and each of the parties shall pay its own expenses and the fees and
expenses of its counsel and other experts.
