ITEM 1.  SECURITY AND ISSUER.

         This statement relates to the Common Stock, par value $.01 per share
(the "Common Stock"), of Bionutrics, Inc., a Nevada corporation (the "Issuer").
The address of the principal executive offices of the Issuer is 2425 E.
Camelback Road, Suite 650, Phoenix, Arizona  85016.

ITEM 2.  IDENTITY AND BACKGROUND.

         (a) This statement is being filed by (i) AC HUMKO CORP., a Delaware
corporation ("AC HUMKO"), with respect to the shares of Common Stock
beneficially owned by it and (ii) The Garfield Weston Charitable Foundation
(the "Foundation") with respect to the shares of Common Stock beneficially
owned by AC HUMKO.  The foregoing persons are sometimes referred to herein as
the "Filing Persons."  Any disclosure herein with respect to persons other than
the Filing Persons are made on information and belief after making inquiry to
the appropriate party.

         AC HUMKO, a Delaware corporation, is a wholly-owned subsidiary in the
Foundation's ownership group.  The Foundation is an English charitable trust
organized under the laws of the United Kingdom.

         (b) The business address of AC HUMKO is 7171 Goodlett Farms Parkway,
Memphis, Tennessee  38101.  The business address of the Foundation is Bowater
House - 68 Knightsbridge, London, SW1X 7LQ, England.

         (c) The principal business of both AC HUMKO and the Foundation is food
processing and commodities.

         (d) During the last five years, none of the persons referred to in
paragraph (a) has been convicted in a criminal proceeding (excluding traffic
violations or similar misdemeanors).

         (e) During the last five years, none of the persons referred to in
paragraph (a) has been a party to a civil proceeding of a judicial or
administrative body of competent jurisdiction as a result of which he was or is
subject to a judgment, decree or final order enjoining future violations of, or
prohibiting or mandating activities subject to, federal or state securities
laws or finding any violation with respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         On August 14, 1998, AC HUMKO entered into a Stock Purchase Agreement
(the "Agreement") dated as of August 14, 1998 with the Issuer pursuant to which
AC HUMKO acquired (i) 2,000,000 shares of Common Stock at $2.00 per share (the
"Shares") and (ii) warrants (the "Warrants") exercisable for 2,000,000 shares
of Common Stock at $2.00 per share, subject to adjustment, for an aggregate
purchase price of $4,000,000.  The transaction was completed on August 14,
1998.  AC HUMKO used funds supplied from its working capital.

ITEM 4.  PURPOSE OF TRANSACTION.

         The Filing Persons entered into the transaction for investment
purposes.  The Filing Persons currently do not intend to acquire additional
shares materially above 17.9% of the Issuer. However, the Filing Persons
intend to review their investment in the Issuer on a continuing basis and,
depending upon the price of the Common Stock, subsequent developments affecting
the Issuer, the Issuer's business and prospects, general stock market and
economic conditions, tax considerations and other factors deemed relevant, may
decide to increase or decrease their investment in the Common Stock of the
Issuer.

         On August 14, 1998, the Issuer, including certain of its subsidiaries,
and AC HUMKO entered into a technology transfer agreement and a supply
agreement for the purpose of transferring certain intellectual property assets
to AC HUMKO.  In addition, the Issuer and AC HUMKO are in discussions regarding
the purchase and sale of certain related operating assets of the Issuer and its
subsidiaries to AC HUMKO.  There can be no assurance, however, that the Filing
Persons and the Issuer will complete the contemplated asset sale transactions.

         Pursuant to the Agreement, the Issuer and certain members of its
management agreed to nominate and vote for AC HUMKO's designee to the Issuer's
board of directors.

         Except as set forth above in this Item 4, none of the Filing Persons
nor, to the best of each Filing Person's knowledge, none of the executive
officers or directors of such Filing Persons, as applicable, has any plans or
proposals that relate to or would result in any of the actions specified in
clauses (a) through (j) of Item 4 to Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a) In addition to the 2,000,000 shares of Common Stock of the Issuer
purchased pursuant to the Agreement, the Filing Persons beneficially own the
right, in the form of currently exercisable warrants, to acquire 2,000,000
shares of Common Stock of the Issuer, which in the aggregate constitute 17.9%
of the Common Stock outstanding based on the number of securities outstanding
(20,329,381), which number is comprised of the Shares and the total number of
shares outstanding as contained in the Issuer's most recent filing on Form 10-Q
(filed June 15, 1998), and including as outstanding the 2,000,000 shares
issuable to AC HUMKO under the Warrants.  Such securities were acquired
pursuant to the transactions described in Item 3 hereof.

         (b) AC HUMKO has sole voting power and power to dispose of the shares
of Common Stock beneficially owned by the Filing Persons.  The Foundation, as
the ultimate parent of AC HUMKO, has shared voting and dispositive power with
respect to such shares.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER

         See Item 4 hereof.

         Pursuant to the Agreement, the Issuer granted certain registration
rights to AC HUMKO with respect to the Shares and with respect to shares of
Common Stock acquired upon the exercise of the Warrants.  These rights include
certain demand registration rights in addition to "piggy-back" registration
rights, each as set forth in the Agreement.

         Pursuant to the Agreement, the Issuer granted certain rights of first
refusal to AC HUMKO to purchase additional securities of the Issuer, up to the
amount of AC HUMKO's pro rata share, and to purchase material assets or
subsidiaries of the Issuer that the Issuer may propose to sell or otherwise
transfer, each as described in the Agreement.

         Pursuant to the Agreement, the Issuer and certain members of its
management agreed to nominate and vote for AC HUMKO's designee to the Issuer's
board of directors.

have a material adverse effect on the business or financial condition of the
Company and its subsidiaries taken as a whole.  Any notice delivered pursuant
to this Section  7.19 shall be accompanied by an officer's certificate
specifying the details of the occurrence referred to therein and stating what
action the Company proposes to take with respect thereto.

         7.21    Environmental Laws.  The Company and its subsidiaries shall
comply with all applicable Environmental laws the failure to comply with which
would have a material adverse effect on the business or financial condition of
the Company and its subsidiaries taken as a whole.  If the Company or any
subsidiary shall receive written notice that there exists a violation of
Environmental law with respect to its operations or any real property owned,
formerly owned, used, or leased thereby, which violation could have a material
adverse effect on the business or financial condition of the Company and its
subsidiaries taken as a whole, the Company shall immediately notify in writing
the Purchaser.  Furthermore, if the Company or any subsidiary shall receive
written notice that there exists a violation of Environmental law with respect
to its operations or any real property owned, formerly owned, used or leased
thereby, which violation could have a material adverse effect on the business
or financial condition of the Company and its subsidiaries taken as a whole,
the Company shall within the time period permitted by the applicable
governmental authority (unless otherwise contested by the Company in good
faith) remove or remedy such violation in accordance with all applicable
Environmental Laws unless the board of directors of the Company determines that
it would be in the best interest of the Company to delay the remedy of such
violation.

         7.22    Listing of Common Stock  The Company warrants and agrees for 
the benefit of the Purchaser that the Shares and the shares of Common Stock
issuable upon exercise of the warrants under the Warrant Agreement shall be
approved for listing, subject to official notice of issuance, on the NASDAQ
(National Market) as of the Closing Date.

         7.23    Right of First Refusal.

         (a)     The Company hereby grants to Purchaser the right of first
refusal, effective so long as it owns the Shares,  to purchase New Securities
(as defined in this section 7.23) that the Company may, from time to time,
propose to sell and issue up to the amount of Purchaser's pro rata share.  A
pro rata share, for purposes of this right of first refusal, is the ratio that
the sum of the number of shares of Common Stock then held by Purchaser and the
number of shares of Common Stock issuable upon conversion or exercise of any
other securities convertible or exercisable into Common Stock then held by
Purchaser bears to the sum of the total number of shares of Common Stock then
outstanding and the number of shares of Common Stock issuable upon conversion
or exercise of any then outstanding other securities convertible or exercisable
into Common Stock (excluding all shares of Common Stock held as treasury shares
by the Company and all shares of Common Stock held by direct or indirect
subsidiaries of the Company).  In the event of a public offering by the
Company, Purchaser shall be permitted to purchase at the public offering price
net of  the underwriting discount directly from the Company either in a
separate transaction or if permitted under applicable securities laws as part
of the registered offering such pro rata amount of securities as provided
above.

         (b)     Except as set forth below, "New Securities" shall mean any
shares of capital stock of the Company, including Common Stock and voting
preferred stock, whether or not now authorized, and rights, options or warrants
to purchase such shares of Common Stock or preferred stock, and securities of
any type whatsoever that are, or may become, convertible into such shares of
Common Stock or preferred stock.  Notwithstanding the foregoing, "New
Securities" does not include:

                 (i)      the Shares or common stock issuable upon exercise of
the Warrant Agreement;

                 (ii)     capital stock issued or issuable to officers,
directors or employees of or consultants to the Company, primarily for the
purpose of soliciting or retaining their services to the Company directly or
pursuant to a stock option plan, restricted stock purchase plan or other
arrangement approved by the compensation committee of the board of directors,
in such amount as shall be approved by such compensation committee, provided
that a majority of the members of which consist of individuals who are not
officers of, or consultants to the Company or any corporation controlling or
controlled by the Company or the Company's direct or indirect parent;





                                       16
<PAGE>   23




                 (iii)    capital stock issued pursuant to any rights or
agreements, including without limitation convertible securities, options and
warrants, provided that the rights of first refusal established by this section
7.23 apply with respect to the initial sale or grant by the Company of such
rights or agreements;

                 (iv)     capital stock issued in connection with any stock
split, stock dividend or recapitalization by the Company; and

                 (v)      securities issued pursuant to the acquisition of
another corporation by the Company by merger, purchase of substantially all of
the assets, or other reorganization whereby the Company owns not less than 50%
of the voting power of the surviving corporation.

         (c)     The Company further grants to Purchaser the right of first
offer, effective so long as it owns the Shares, to purchase any and all
material assets or any and all direct or indirect subsidiaries of the Company
("Assets Held for Sale") that the Company may, from time to time, propose to
sell or otherwise transfer.

         (d)     If subsections (a) and (c) apply in the event the Company
proposes to undertake an issuance of New Securities or dispose of Assets Held
for Sale, it shall promptly give Purchaser written notice of its intention,
describing the type of New Securities or the Assets Held for Sale, as
appropriate, and the price and general terms upon which the Company proposes to
issue or transfer the same.  The Purchaser shall have twenty (20) business days
(or the greater of (x) five (5) business days or (y) such period as otherwise
mutually agreed to by the parties, in the case of New Securities offered solely
to officers or directors of the Company) from the date of receipt of any such
notice to agree to purchase up to its respective pro rata share of such New
Securities or the Assets Held for Sale, as appropriate, for the price and upon
the terms specified in the notice by giving written notice to the Company and,
in the case of New Securities, stating therein the quantify of New Securities
to be purchased.

         (e)     Purchaser's notice to the Company of exercise of its rights
under this Section 7.23 shall constitute Purchaser's irrevocable acceptance of
the Company's offer, subject to customary closing conditions.

         (f)     The purchase and sale of any securities or assets pursuant to
any offer made under this Section 7.23 that is accepted by the Purchaser shall
take place at such time and place as the Company and the Purchaser may mutually
agree.  The purchase price shall be payable in such form as mutually agreed by
the Company and Purchaser or, in the case of New Securities, in such other form
as set forth in the terms to the new investors.   The issuance of such shares
shall be conditioned upon compliance with applicable laws and regulations and
requirements of any applicable stock exchange and the absence of any order in
effect enjoining or restraining such exercise or issuance.

         (g)     In the event Purchaser fails to exercise the right of first
refusal or offer as the case may be within the period set forth in Section
7.23 (d), as appropriate, the Company shall have ninety (90) days thereafter to
sell or enter into an agreement (pursuant to which the sale of New Securities
or the Assets Held for Sale, as appropriate covered thereby shall be closed, if
at all, within sixty (60) days from the date of said agreement) to sell the New
Securities or the Assets Held for Sale, as appropriate, not elected to be
purchased by Purchaser at the price and upon terms no more favorable to the
purchasers of such securities or assets than specified in the Company's notice.

         7.24    Purchaser's Director Nominee.  The Company and the Key
Management Employee/Directors listed on the signature page hereto shall
nominate and vote for the Purchaser's designee to the board of directors of the
Company so long as Purchaser shall own the Shares or Common Stock underlying
the Warrant Agreement.

                                   Section 8

                       Restrictions on Transferability of
                   Securities; Compliance With Securities Act

         8.1     Restrictions on Transferability.  The Shares shall not be
transferable, except upon the conditions specified in this section 8, which
conditions are intended to insure compliance with the provisions of the
Securities Act of 1933, as amended (the "Securities Act").  Purchaser shall
cause any proposed transferee of Shares to agree to take and hold those
securities subject to the provisions and upon the conditions specified in this
section 8.

         8.2     Certain Definitions.  As used in this section 8, "Restricted
Securities" shall mean the securities of the Company required to bear or
bearing the legend set forth in section 8.3.

         8.3     Restrictive Legend.  Each certificate representing the Shares,
or shares of Common Stock issued upon exercise of the warrants under the
Warrant Agreement, or any other securities issued in respect of the Preferred
Shares or the Common Stock issued upon exercise of the warrants under the
Warrant Agreements, upon any stock split, stock dividend, recapitalization,
merger, consolidation or similar event, shall (unless otherwise permitted or
unless the securities evidenced by such certificate shall have been registered
under the Securities Act) be stamped or otherwise imprinted with a legend in
the following form (in addition to any legend required under applicable state
securities laws):

                          THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
                          SECURITIES ACT OF 1933 OR ANY STATE SECURITIES LAWS.
                          THEY MAY NOT BE SOLD OR OFFERED FOR SALE IN THE
                          ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
                          COVERING THE SECURITIES UNDER SUCH ACT AND ANY
                          APPLICABLE STATE SECURITIES LAW OR AN OPINION OF
                          COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT
                          SUCH REGISTRATION IS NOT REQUIRED.

Upon request of Purchaser, the Company shall remove the foregoing legend from
the certificate or issue thereto a new certificate therefor free of any
transfer legend provided that the Company receives either the opinion referred
to in section 8.4(i) or the "no-action" letter referred to in section 8.4(ii)
to the effect that any transfer by Purchaser of the securities evidenced by
such certificate will not violate the Securities Act or applicable state
securities laws.

         8.4     Notice of Proposed Transfers.  The holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply with
this section 8.4.  Prior to any proposed transfer of any Restricted Securities
the holder thereof shall give written notice to the Company of such holder's
intention to effect such transfer.  Each such notice shall describe the manner
and circumstances of the proposed transfer in sufficient detail, and shall be
accompanied (except in transactions in compliance with Rule 144) by either (a)
a written opinion of  legal counsel reasonably satisfactory to the Company,
addressed to the Company and reasonably satisfactory in form and substance to
the Company's counsel, to the effect that the proposed transfer of the
Restricted Securities may be effected without registration under the Securities
Act or (b) a "no action" letter from the Commission to the effect that the
distribution of such securities without registration will not result in a
recommendation by the staff of the Commission that action be taken with respect
thereto, whereupon the Holder of such Restricted Securities shall be entitled
to transfer such Restricted Securities in accordance with the terms of the
notice delivered by the holder to the Company.  Each certificate evidencing the
Restricted Securities transferred as above provided shall bear the appropriate
restrictive legend set forth in section 8.3, except that such certificate shall
not bear such restrictive legend if the opinion of





                                       18
<PAGE>   25



counsel or "no-action" letter referred to above is to the further effect that
such legend is not required in order to establish compliance with the Securities
Act.

         8.5     Information by Holder.  Each holder of Restricted Securities
shall furnish to the Company such information regarding the transfer or
distribution proposed by such holder as the Company may reasonably request in
writing.

         8.6     Rule 144 Reporting.  With a view to making available the
benefits of certain rules and regulations of the Commission that may permit the
sale of the Restricted Securities to the public without registration, the
Company shall (a)  make and keep public information available as those terms
are understood and defined in Rule 144 under the Securities Act,  (b)  use its
best efforts to file with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Securities Exchange Act of 1934 (the "Exchange Act") and (c) so long as
Purchaser owns any Shares, furnish to Purchaser upon request a written
statement by the Company as to its compliance with the reporting requirements
of Rule 144 and of the Securities Act and Exchange Act and a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed as it may reasonably request in availing itself of any rule
or regulation of the Commission allowing it to sell any such securities without
registration.

         8.7     "Market Stand-off" Agreement.  Purchaser shall agree, if
requested by the Company and the managing underwriter of Common Stock (or other
securities) of the Company, not to sell or otherwise transfer or dispose of any
Common Stock (or other securities) of the Company held by it during the 90-day
period following the effective date of a registration statement of the Company
filed under the Securities Act, provided that (a)  such agreement shall apply
only to the first such registration statement of the Company including
securities to be sold on its behalf to the public in an underwritten offering
and (b)  the officers and directors of the Company shall enter into similar
agreements.  Such agreement shall be in writing in a form satisfactory to the
Company and such underwriter.  The Company may impose stop-transfer
instructions with respect to the Shares (or securities) subject to the
foregoing restriction until the end of such 90-day period.

                                   Section 9

                    Registration under Securities Act, etc.

         9.1      Registration of Registrable Securities on Request. 
(a)  Request.  At any time commencing 18 months from the date hereof, the
Purchaser (and any transferee of Purchaser's Registrable Securities (as defined
below)) shall   have the right to request in writing specifying that such
request is made pursuant to this Section 9.1, that the Company effect an
underwritten registration under the Securities Act on form S-3 or such other
form of registration statement that the Company is otherwise eligible to use for
such purpose of all or part of such holders' Registrable Securities. The Company
shall be obligated to effect only two (2) registrations pursuant to this Section
9.1 with respect to all holders of Registrable Securities and only until the
earlier of the date that all Registrable Securities have been sold or the date
that all Registrable Securities are freely transferable without restriction
under the Securities Act.  The Company will promptly give written notice of
such requested registration to all other holders of Registrable Securities,
which holders shall be entitled to include their Registrable Securities in such
registration subject to Section 9.1(b).  Thereupon the Company will use its best
efforts to effect the registrations under the Securities Act of:

                 (i)      the Registrable Securities which the Company has been
         so requested to register by such holders making the demand pursuant to
         this Section 9.1, and





                                       19
<PAGE>   26




                 (ii)     subject to Section 9.1(b), all other Registrable
         Securities which the Company has been requested to register by the
         holders thereof by written request given to the Company within 30 days
         after the giving of such written notice by the Company (which request
         shall specify the intended method of disposition of such Registrable
         Securities) all to the extent requisite to permit the disposition of
         the Registrable Securities so to be registered.

         The Company will not grant to any person at any time on or after the
date hereof the right (a "Piggyback Right") to request the Company to register
any securities of the Company under the Securities Act by reason of the
exercise by any holder of its rights under this Section 9.1 unless such
Piggyback Right provides that such securities shall not be registered and sold
at the same time if the managing underwriter for the respective holders
believes that sale of such securities would adversely affect the amount of, or
price at which, the respective Registrable Securities being registered under
this Section 9.1 can be sold.  For purposes of this agreement, "Registrable
Securities" shall mean the Shares and all other shares of Common Stock issuable
upon exercise of the warrants under the Warrant Agreement.

         (b)     Registration of Other Securities.  Whenever the Company shall
effect a registration pursuant to this Section 9.1, no securities other than
Registrable Securities shall be included among the securities covered by such
registration unless (i) the managing underwriter of such offering shall have
advised each holder of Registrable Securities to be covered by such
registration in writing that the inclusion of such other securities would not
in the underwriter's reasonable judgment adversely affect such offering or (ii)
the holders of a majority of Registrable Securities to be covered by such
registration shall have consented in writing to the inclusion of such other
securities.

         (c)     Registration Statement Form.  Registrations under this Section
9.1 shall be on such appropriate registration form or prospectus of the
Commission (i) as shall be selected by the Company and as shall be reasonably
acceptable to the holders of more than 50% (by number of shares then
outstanding) of the Registrable Securities so to be registered and (ii) as
shall permit the disposition of such Registrable Securities in accordance with
the intended method or methods of disposition specified in their request for
such registration.  The Company agrees to include in any such registration
statement all information which holders of Registrable Securities being
registered shall reasonably request.

         (d)     Expenses.  The Company will pay all Registration Expenses in
connection with the registration requests made pursuant to this Section 9.1,
provided, however, that the Company shall not be required to pay expenses of
any registration proceeding begun pursuant to Section 9.1 if the registration
is subsequently withdrawn (other than by reason of the Company's failure to
perform its obligations hereunder or a material adverse change in the Company's
financial position or business), unless the holder agrees to forfeit his right
to a demand registration under Section 9.1.  If such registration is withdrawn
(other than by reason of the Company's failure to perform its obligations
hereunder or a material adverse change in the Company's financial position or
business), the holder shall have the option to pay the expenses of such
registration and preserve all of his rights to demand registrations under
Section 9.1.

         No holder shall have the right to cause the Company to employ any
expert or professional to act on behalf of the Company other than any expert or
professional, such as an independent accountant, whose report or consent is
required to be included in a registration statement for the Registrable
Securities.

         Effective Registration Statement.  A registration requested pursuant to
this Section 9.1 shall not be deemed to have been effected and shall not count
as a requested registration pursuant to Section 9.1 (a) hereof (i) unless a
registration statement with respect thereto has become effective, (ii) if after
it has become effective, such registration





                                       20
<PAGE>   27



is interfered with by any stop order, injunction or other order or requirement
of the Commission or other governmental agency or court for any reason not the
fault of a holder of Registrable Securities and the Registrable Securities
covered hereby have not been sold, or (iii) if the conditions to closing
specified in the selling agreement or underwriting agreement entered into in
connection with such registration are not satisfied or waived by the parties
thereto other than a holder of Registrable Securities.

         (f)     Underwriters.  Any registration effected pursuant to this
Section 9.1 shall at the election of the holders of at least 50% by number of
shares then outstanding of the Registrable Securities to be so registered by an
underwritten public offering on a firm commitment basis or a best efforts
basis.  The managing underwriter or underwriters thereof shall be selected by
the Company, and such underwriter, as well as the price, terms and provisions
of the offering, shall be subject to the approval of the holders of more than
50% (by number of shares then outstanding) of the Registrable Securities to be
so registered.

         (g)     Apportionment in Registrations Requested.  If, in connection
with a registration requested pursuant to this Section 9.1, the managing
underwriter shall advise the Company in writing (with a copy to each holder of
Registrable Securities requesting registration) that, in its opinion, the
number of securities requested to be included in such registration exceeds the
number which can be sold in such offering within a price range acceptable to
the holders of more than 50% (by number of shares then outstanding) of the
Registrable Securities requested to be included in such registration, the
Company will include in such registration, to the extent of the number which
the Company is so advised can be sold in such offering, Registrable Securities
requested to be included in such registration pro rata among the holders
thereof requesting such registration on the basis of the percentage of the
Registrable Securities of the Company held by the holders of Registrable
Securities which have requested that such Registrable Securities be included.
In connection with any registration as to which the provisions of this clause
(g) apply, no securities other than Registrable Securities shall be covered by
such registration and if the pro ration as aforesaid results in the exclusion
of in excess of 20% of the Registrable Securities originally sought to be
registered, the request shall not be counted for purposes of determining the
number of registrations pursuant to Section 9.1 hereof.

         9.2     Incidental Registration. (a)  Right to Include Registrable
Securities.  If the Company at any time proposes to register any of its Common
Stock under the Securities Act (other than by a registration on Form S-4, Form
S-8 or any successor or similar form), whether or not for sale for its own
account, it will each such time give prompt written notice to all holders of
Registrable Securities of its intention to do so.

         Upon the written request of any such holder made within 30 days after
the date of any such notice given in accordance with Section 11.5 hereof, the
Company will use its best efforts to effect the registration under the
Securities Act of all Registrable Securities which the Company has been so
requested to register by the holders thereof, to the extent requisite to permit
the disposition of the Registrable Securities so to be registered, provided
that if, at any time after giving written notice of its intention to register
any securities and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any
reason not to register or to delay registration of such securities, the Company
may, at its election, give written notice of such determination to each holder
of Registrable Securities and, thereupon, (i) in the case of a determination
not to register, shall be relieved of its obligation to register any
Registrable Securities in connection with such registration (but not from its
obligation to pay the Registration Expenses in connection therewith), without
prejudice, however, to the rights of any holder or holders of Registrable
Securities entitled to do so to request that such registration be effected as a
registration under Section 9.2, and (ii) in the case of a determination to
delay registering, shall be permitted to delay registering any Registrable
Securities, for the same period as the delay in registering such other
securities.  No registration effected under this Section 9.2 shall relieve the
Company of its obligation to effect any registration upon request under Section
9.1.  The Company will pay all Registration Expenses in connection with each
registration of





                                       21
<PAGE>   28



Registrable Securities requested pursuant to this Section 9.2.  No holder shall
have the right to cause the Company to employ any expert or professional to act
on behalf of the Company other than any expert or professional, such as an
independent engineer or accountant, whose report or consent is required to be
included in a registration statement for the Registrable Securities.

         (b)     Apportionment in Incidental Registrations.  If (i) a
registration pursuant to this Section 9.2 involves an underwritten offering of
the securities being registered, whether or not for sale for the account of the
Company, to be distributed (on a firm commitment basis) by or through one or
more underwriters of recognized national or regional standing under
underwriting terms appropriate for such a transaction, and (ii) the managing
underwriter of such underwritten offering shall inform the Company and the
holders of the Registrable Securities requesting such registration by letter of
its belief that the number of securities requested to be included in such
registration exceeds the number which can be sold in (or during the time of)
such offering or that the inclusion would adversely affect the marketing of the
securities to be sold by the Company therein, then the Company may include all
securities proposed by the Company to be sold for its own account and may
decrease the number of Registrable Securities and other securities of the
Company so proposed to be sold and so requested to be included in such
registration (pro rata on the basis of the percentage of the securities of the
Company sought to be registered by the holders of such Registrable Securities
and such other securities) to the extent necessary to reduce the number of
securities to be included in the registration to the level recommended by the
managing underwriter.  Notwithstanding the foregoing, if the registration
referred to herein involves an underwritten offering of securities being
registered for sale by holders of securities other than registrable Securities,
the Company will include in such registration the securities proposed by such
holders to be sold and may decrease the number of Registrable Securities and
such other securities exercising incidental registration rights proposed to be
sold in such registration (pro rata on the basis of the percentage of the
securities sought to be registered held by such holders of Registrable
Securities and such other securities exercising incidental registration rights)
to the extent necessary to reduce the number of securities to be included in
the registration to the level recommended by the managing underwriter.  In such
case, no securities shall be offered for sale by the Company.

         (c)     The Registrable Securities proposed to be registered under any
registration statement under Section 9.2 hereof will be offered for sale at the
same public offering price as the shares of Common Stock offered for sale by
the Company or any other selling shareholder covered thereby.

         9.3     Registration Procedures.  If and whenever the Company is
required to use its best efforts to effect the registration of any Registrable
Securities under the Securities Act as provided in Sections 9.1 and 9.2, the
Company will as expeditiously as possible:

                 (i)      prepare and (as soon thereafter as possible or in any
         event no later than 90 days after the end of the period within which
         requests for registration may be given to the Company) file with the
         Commission the requisite registration statement to effect such
         registration and thereafter use its best efforts to cause such
         registration statement to become effective, provided that the Company
         may discontinue any registration of its securities which are not
         Registrable Securities (and, under the circumstances specified in
         Section 9.2(a), its securities which are Registrable Securities) at
         any time prior to the effective date of the registration statement
         relating thereto; and provided, further, that the Company may defer
         its obligations under Section 9.1 for a period of no more than ninety
         (90) days if the Company's Board of Directors adopts a resolution that
         filing such a registration statement would require a public disclosure
         by the Company which disclosure would have material adverse
         consequences for the Company, such as a disclosure regarding a pending
         material acquisition by the Company or a material discovery of oil and
         gas reserves; provided,





                                       22
<PAGE>   29



         further, that once such information has been publicly disclosed, then

         statement effective and to comply with the provisions of the
         Securities Act with respect to the disposition of all securities
         covered by such registration statement until such time as all of such
         securities have ben disposed of in accordance with the intended
         methods of disposition by the seller or sellers thereof set forth in
         such registration statement;

                 (iii)    furnish to each seller of Registrable Securities
         covered by such registration statement such number of conformed copies
         of such registration statement and of each such amendment and
         supplement thereto, such number of copies of the prospectus contained
         in such registration statement (including each preliminary prospectus
         and any summary prospectus) and any other prospectus filed under Rule
         424 or Rule 430A under the Securities Act, in conformity with the
         requirements of the Securities Act, and such other documents, as such
         seller may reasonably request;

                 (iv)     use its best efforts to register or qualify all
         Registrable Securities and other securities covered by such
         registration statement under such other securities or blue sky laws of
         such jurisdictions as each seller thereof shall reasonably request, to
         keep such registration or qualification in effect for so long as such
         registration statement remains in effect, and take any other action
         which may be reasonably necessary to enable such seller to consummate
         the disposition in such jurisdictions of the securities owned by such
         seller, except that the Company shall not for any such purpose be
         required to qualify generally to do business as a foreign corporation
         in any jurisdiction wherein it would not but for the requirements of
         this subdivision (iv) be obligated to be so qualified or to consent to

                 the effective date of such registration statement (and, if
                 such registration includes an underwritten public offering,
                 dated the date of the closing under the underwriting
                 agreement), reasonably satisfactory in form and substance to
                 such seller or, if such registration includes an underwritten
                 public offering, to such underwriter, and

                          (y)     a "comfort" letter, dated the effective date
                 of such registration statement (and, if such registration
                 includes an underwritten public offering, dated the date of
                 the closing under the underwriting agreement), signed by the

                 Company's financial statements included in such registration
                 statement, addressed to each seller, to the extent the same
                 can be reasonably obtained, and addressed to the underwriters,
                 if any, covering substantially the same matters with respect
                 to such registration





                                       23
<PAGE>   30



                 statement (and the prospectus included therein) and, in the
                 case of the accountants' letter, with respect to events
                 subsequent to the date of such financial statements, as are
                 customarily covered in accountants' letters delivered to the
                 underwriters in underwritten public offerings of securities
                 and such other financial matters as such seller or such holder
                 (or the underwriters, if any) may reasonably request;

                 (vii)    notify each seller of Registrable Securities covered
         by such registration statement, at any time when a prospectus relating
         thereto is required to be delivered under the Securities Act, upon
         discovery that, or upon the happening of any event as a result of
         which, the prospectus included in such registration statement, as then
         in effect, includes an untrue statement of a material fact or omits to
         state any material fact required to be stated therein or necessary to
         make the statements therein not misleading in the light of the
         circumstances under which they were made, and at the request of any
         such seller or holder promptly prepare to furnish to such seller or
         holder a reasonable number of copies of a supplement to or an
         amendment of such prospectus as may be necessary so that, as
         thereafter delivered to the purchasers of such securities, such
         prospectus shall not include an untrue statement of a material fact or
         omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading in the light
         of the circumstances under which they were made;

                 (viii)   otherwise use its best efforts to comply with all
         applicable rules and regulations of the Commission, and make available
         to its security holders, as soon as reasonably practicable, an
         earnings statement covering the period of at least twelve months, but
         not more than eighteen months, beginning with the first fiscal quarter
         beginning after the effective date of such registration statement,
         which earnings statement shall satisfy the provisions of Section 11(a)
         of the Securities Act, and, in the case of a registration requested
         pursuant to Section 9.1 hereof, will furnish to each such seller at
         least two business days prior to the filing thereof a copy of any
         amendment or supplement to such registration statement or prospectus
         and shall not file any thereof to which any such seller shall have
         reasonably objected on the grounds that such amendment or supplement
         does not comply in all material respects with the requirements of the
         Securities Act or of the rules or regulations thereunder;

                 (ix)     provide and cause to be maintained a transfer agent
         and registrar for all Registrable Securities covered by such
         registration statement from and after a date not later than the
         effective date of such registration statement; and

                 (x)      use its best efforts to list all Registrable
         Securities covered by such registration statement on any securities
         exchange on which any of the Registrable Securities is then listed.

The Company may require each proposed seller of Registrable Securities as to
which any registration is being effected to promptly furnish the Company, as a
condition precedent to including such holder's Registrable Securities in any
registration, such information regarding such seller and the distribution of
such securities as the Company may from time to time reasonably request in
writing.

         Each holder of Registrable Securities agrees by acquisition of such
Registrable Securities that upon receipt of any notice from the Company of the
happening of any event of the kind described in subdivision (vii) of this
Section 9.3, such holder will forthwith discontinue such holder's disposition
of Registrable Securities pursuant to the registration statement relating to
such Registrable Securities until such holder's receipt of the copies of the
supplemented or amended prospectus contemplated by subdivision (vii) of this
Section 9.3 and, if so directed by the





                                       24
<PAGE>   31



Company, will deliver to the Company (at the Company's expense) all copies,
other than permanent file copies, then in such holder's possession of the
prospectus relating to such Registrable Securities current at the time of
receipt of such notice.

         9.4     Underwritten Offerings. (a)  Requested Underwritten Offerings.
If requested  by the underwriters for any offering by holders of Registrable
Securities pursuant to a registration requested under Section 9.1, the Company
will enter into an underwriting agreement with such underwriters for such
offering, such agreement to be satisfactory in substance and form to the
Company, to holders of more than 50% of the Registrable Securities included in
such registration and the underwriters and to contain such representations and
warranties by the Company and such other terms as are generally prevailing in
agreements of this type, including, without limitation, indemnities to the
effect and to the extent provided in Section 9.6.  The holders of the
Registrable Securities will cooperate with the Company in the negotiation of
the underwriting agreement and will give consideration to the reasonable
requests of the Company regarding the form thereof, provided that nothing
herein contained shall diminish the foregoing obligations of the Company.  The
holders of Registrable Securities to be distributed by such underwriters shall
be parties to such underwriting agreement and may, at their option, require
that any or all of the representations and warranties by, and the other
agreements on the part of, the Company to and for the benefit of such
underwriters shall also be made to and for the benefit of such holders of
Registrable Securities and that any or all of the conditions precedent to the
obligations of such underwriters under such underwriting agreement be
conditions precedent to the obligations of such holders of Registrable
Securities.  Other than as required under Section 9.3 hereof, any such holder
of Registrable Securities shall not be required to make any representations or
warranties to or agreements with the Company or the underwriters other than
representations, warranties or agreements regarding such holder, such holder's
Registrable Securities, and such holder's intended method of distribution, any
other information supplied by such holder to the Company for use of the
Registration Statement and any other representation required by law.

         (b)     Incidental Underwritten Offerings.  If the Company at any time
proposes to register any of its securities under the Securities Act as
contemplated by Section 9.2 and such securities are to be distributed by or
through one or more underwriters, the Company will, if requested by any holder
of Registrable Securities as provided in Section 9.2 and subject to the
provisions of Sections 9.2(a), 9.2(b) and 9.3, arrange for such underwriters to
include all the Registrable Securities to be offered and sold by such holder
among the securities to be distributed by such underwriters.  The holders of
Registrable Securities to be distributed by such underwriters shall be parties
to the underwriting agreement between the Company and such underwriters and
may, at their option, require that any or all of the representations and
warranties by, and the other agreements on the part of, the Company to and for
the benefit of such underwriters shall also be made to and for the benefit of
such holders of Registrable Securities and that any or all of the conditions
percent to the obligations of such underwriters under such underwriting
agreement be conditions precedent to the obligations of such holders of
Registrable Securities.  Other than as required under Section 9.3 hereof, any
such holder of Registrable Securities shall not be required to make any
representations or warranties to or agreements with the Company or the
underwriters other than representations, warranties, or agreements regarding
such holder, such holder's Registrable Securities and such holder's intended
method of distribution, any other information supplied by such holder to the
Company for use in the Registration Statement and any other representation
required by law.

         9.5     Preparation; Reasonable Investigation.  In connection with the
preparation and filing of each registration statement under the Securities Act
pursuant to this Agreement, the Company will give the holders of Registrable
Securities registered under such registration statement, their underwriters, if
any, and their respective counsel and firm of accountants (such holders'
counsel and firm of accountants to be appointed by the holders of a majority of
such Registrable Securities), the opportunity to participate in the preparation
of such registration statement, each prospectus included therein or filed with
the Commission, and each amendment thereof or supplement thereto,





                                       25
<PAGE>   32



and will give each of them such access to its books and records and such
opportunities to discuss the business of the Company with its officers and the
independent public accountants who have certified its financial statements as
shall be necessary, in the opinion of such holders' and such underwriters'
respective counsel, to conduct a reasonable investigation within the meaning of
the Securities Act.

         9.6     Indemnification.  (a)  Indemnification by the Company.  In the
event of any registration of any Registrable Securities of the Company under
the Securities Act pursuant to this Agreement, the Company will, and hereby
does, indemnify and hold harmless the seller of any Registrable Securities
covered by such registration statement, its directors and officers, each other
Person who participates as an underwriter in the offering or sale of such
securities and such other Person, if any, who controls such seller or any such
underwriter within the meaning of the Securities Act, against any losses,
claims, damages or liabilities, joint or several, to which such seller or any
such director or officer or underwriter or controlling person may become
subject under the Securities Act or any other statute or at common law, insofar
as such losses, claims, damages or liabilities (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained, on the effective date thereof, in any registration statement under
which such Registrable Securities were registered under the Securities Act, or
in any preliminary prospectus, final prospectus or summary prospectus contained
therein, or any amendment or supplement thereto, or any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and the Company will
reimburse such seller and each such director, officer, underwriter and
controlling person for any legal or any other expenses reasonably incurred by
them in connection with investigating or defending any such loss, claim,
liability, action or proceeding; provided that the Company shall not be liable
in any such case to the extent that any such loss, claim, damage, liability (or
action or proceeding in respect thereof) or expense arises out of or is based
upon an untrue statement or alleged untrue statement or omission or alleged
omission made in such registration statement, any such preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement in reliance upon
and in conformity with written information furnished to the Company through an
instrument duly executed by such seller for use in the preparation thereof.
Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of such seller or any such director,
officer, underwriter or controlling person and shall survive the transfer of
such securities by such seller.

         (b)     Indemnification by the Purchasers.  The Purchasers will, and
hereby do, indemnify and hold harmless (in the same manner and to the same
extent as set forth in subdivision (a) of this Section 9.6) the Company, each
director of the Company, each officer of the Company and each other Person, if
any, who controls the Company within the meaning of the Securities Act with
respect to any statement or alleged statement in or omission or alleged
omission from such registration statement, any preliminary prospectus, final
prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, if such statement or alleged statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Purchaser for use in the
preparation of such registration statement, preliminary prospectus, final
prospectus, summary prospectus, amendment or supplement.  Such indemnity shall
remain in full force and effect, regardless of any investigation made by or on
behalf of the Company or any such director, officer or controlling Person and
shall survive the transfer of such securities by such Purchaser.

         (c)     Notices of Claims, etc.  Promptly after receipt by an
indemnified party of notice of the commencement of any action or proceeding
involving a claim referred to in the preceding subdivisions of this Section
9.6, such indemnified party will, if a claim in respect thereof is to be made
against an indemnifying party, give written notice to the latter of the
commencement of such action, provided that the failure of any indemnified party
to give notice as provided herein shall not relieve the indemnifying party of
its obligations under the preceding subdivisions of this Section 9.6, except to
the extent that the indemnifying party is prejudiced by such failure to give





                                       26
<PAGE>   33



notice.  In case any such action is brought against an indemnified party,
unless in such indemnified party's reasonable judgment a conflict of interest
between such indemnified party and indemnifying parties may exist in respect of
such claim, the indemnifying party shall be entitled to participate in and to
assume the defense thereof, jointly with any other indemnifying party similarly
notified to the extent that it may wish, with counsel reasonably satisfactory
to such indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation.  No indemnifying
party shall, without the consent of the indemnified party, consent to entry of
any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect to such claim or
litigation.

         (d)     Other Indemnification.  Indemnification similar to that
specified in the preceding subdivisions of this Section 9.6 (with appropriate
modifications) shall be given by the Company and each seller of Registrable
Securities with respect to any required registration or other qualification of
securities under any Federal or state law or regulation of any governmental
authority other than the Securities Act.

         (e)     Indemnification Payments.  The indemnification required by
this Section 9.6 shall be made by periodic payments of the amount thereof
during the course of the investigation or defense, as and when bills are
received or expense, loss, damage or liability is incurred.

         9.7     Rule 144.  If the Company shall have filed a registration
statement pursuant to the requirements of Section 12 of the Exchange Act or a
registration statement pursuant to the requirements of the Securities Act, the
Company will file the reports required to be filed by it, and in the manner
required to be filed by it, under the Securities Act and the Exchange Act (or,
if the Company is not required to file such reports, will, upon the request of
any holder of Registrable Securities, make publicly available other
information) and will take such further action as any holder of Registrable
Securities may reasonably request, all to the extent required from time to time
to enable such holder to sell Registrable Securities without registration under
the Securities Act within the limitation of the exemptions provided by (a) Rule
144 under the Securities Act, as such Rule may be amended from time to time or
(b) any similar rule or regulation hereafter adopted by the Commission ("Rule
144").  Upon the request of any holder of Registrable Securities, the Company
will deliver to such holder a written statement as to whether it has complied
with such requirements.

                                   Section 10

                                Indemnification

         10.1    Obligation of the Company to Indemnify.  Subject to section
11.2, the Company shall indemnify, defend and hold harmless Purchaser (and its
respective partners, directors, officers, employees, affiliates and assigns)
from and against all losses, liabilities, damages, deficiencies, diminution in
value, costs or expenses (including interest and penalties imposed or assessed
by any judicial or administrative body and reasonable attorneys' fees)
(collectively, "Losses") based upon, arising out of or relating to any
inaccuracy or in any breach of any representation, warranty, covenant or
agreement of the Company contained in this agreement or in the Disclosure
Schedule or any exhibit, schedule certificate or any of the other Transaction
Documents delivered by the Company at the Closing.

<PAGE>   34



         10.2    Obligation of Purchaser to Indemnify.  Subject to section
11.2, Purchaser shall indemnify, defend and hold harmless the Company from and
against any Losses based upon, arising out of or relating to any breach of any
representation, warranty, covenant or agreement of Purchaser contained in this
agreement or in any exhibit, schedule or certificate delivered by Purchaser at
the Closing.

         10.3    Notice and Opportunity to Defend.  (a) Within 30 days after
receipt by any party hereto (the "Indemnitee") of notice of any demand, claim
or circumstance that, with the lapse of time, would give rise to a claim or the
commencement (or threatened commencement) of any action, proceeding or
investigation or within 30 days of an Indemnitee learning that a representation
or warranty is materially inaccurate, in each case that may result in a Loss
(an "Asserted Liability"), the Indemnitee shall give notice thereof (the
"Claims Notice") to the party required to provide indemnification pursuant to
section 10.1 or 10.2 hereof (the "Indemnitor").  The Claims Notice shall
describe the Asserted Liability in reasonable detail, and shall indicate the
amount (estimated, if necessary) of the Loss that has been or may be suffered
by the Indemnitee.

                  (b)  Opportunity to Defend.  The Indemnitor may elect to
compromise or defend, and control the defense of, at its own expense and by
counsel reasonably satisfactory to the Indemnitee, any Asserted Liability
provided that the Indemnitee shall have no liability under any compromise or
settlement agreed to by the Indemnitor that it has not approved in writing.  If
the Indemnitor elects to compromise or defend such Asserted Liability, it shall
within 30 days (or sooner, if the nature of the Asserted Liability so requires)
notify the Indemnitee of its intent to do so, and the Indemnitee shall
cooperate upon the request and at the expense of the Indemnitor in the
compromise of, or defense against, such Asserted Liability.  If the Indemnitor
elects not to compromise or defend against the Asserted Liability, or fails to
notify the Indemnitee of its election as herein provided, the Indemnitee may
pay, compromise or defend such Asserted Liability and receive full
indemnification for its Losses as provided in sections 10.1 and 10.2.  In any
event, the Indemnitee and the Indemnitor may participate, at their own expense,
in the defense of such Asserted Liability by the Indemnitor or the Indemnitee,
respectively.  If the Indemnitor chooses to defend any claim, the Indemnitee
shall make available to the Indemnitor any books, records or other documents
within its control that are reasonably requested for such defense and shall
otherwise cooperate with the Indemnitor, in which event the Indemnitee shall be
reimbursed for its out-of-pocket expense.

impair any such party's right, power or remedy nor construed to be a waiver of
any such breach or default, or an acquiescence therein, or of any similar

                                                                       EXHIBIT A


                 Warrant Agreement dated August 14, 1998 between Bionutrics,
Inc., a Nevada corporation (the "Company"), and AC Humko Corp., a Delaware
corporation and its permitted transferees (hereinafter referred to as
"Holder").

                 Whereas Holder is purchasing certain securities of the Company
pursuant to that certain stock purchase agreement dated August 14, 1998 (the
"Purchase Agreement"); and

                 Whereas pursuant to the terms of the Purchase Agreement the
Company has agreed to issue Holder certain warrants to purchase shares of the
Company's Common Stock (as defined in section 8.8); and

                 Now therefore for good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto agrees as
follows:

         1.      Grant.  The Company hereby grants to Holder warrants to
purchase up to an aggregate of two million shares of Common Stock ("Warrants")
at the Exercise Price (as defined in section 2), subject to adjustment as
provided in section 8, during the period commencing on the date hereof and
ending at 5:30 p.m. Eastern Standard Time two years thereafter ("Exercise
Period").

         2.      Exercise Price.  The term "Exercise Price"  for 2 million
shares of Common Stock shall be $2.00 per share as may be adjusted from time to
time pursuant to Section 8.

         3.      Warrant Certificate.  The warrant certificate delivered
pursuant to this Warrant Agreement shall be in the form set forth in exhibit A
with such appropriate insertions, omissions, substitutions and other variations
as required or permitted by this Warrant Agreement (the "Warrant Certificate").

         4.      Exercise of Warrants.  The Warrants are exercisable at the
Exercise Price and payable to the Company at its executive offices located at
2425 East Camelback Road, Ste. 650, Phoenix, AZ  85016, attn: Chief Financial
Officer (or such other officer as designated to Holder by the Company) by
certified or official bank check in New York Clearing House funds or wire
transfer. Upon surrender of a Warrant Certificate, submission of an





                                      A-1
<PAGE>   38





executed Form of Election to Purchase in the form set forth in Exhibit B and
payment of the Exercise Price, Holder shall be entitled to receive a certificate
for the shares of Common Stock so purchased. The purchase rights represented by
the Warrant Certificate are exercisable at the option of Holder in whole or in
part, but not as to fractional shares of the Common Stock underlying the
Warrants provided the Company shall pay cash in respect of any fraction of a
share  that would otherwise be issuable in an amount equal to the same fraction
of the market price per share of the shares of Common Stock underlying the
Warrants on the date of the exercise, as reasonably determined by the Company.

         5.      Issuance of Certificates.  Upon the exercise of Warrants the
Company shall promptly issue to Holder a certificate for the shares of Common
Stock underlying the Warrant Certificate.  If Holder purchases less than all
the shares of Common Stock purchasable under the Warrant Certificate, the
Company shall cancel the Warrant Certificate upon the surrender thereof and
shall execute and deliver a new Warrant Certificate of like tenor for the
balance of the shares of Common Stock.  Holder shall be deemed the record
holder of the shares of Common Stock on the date of exercise of the Warrant
pursuant to section 4, irrespective of the date of delivery of the Common Stock
certificate.

         6.      Restriction On Transfer of Warrants.  Holder may not sell,
assign, pledge, hypothecate or otherwise transfer any rights under the Warrants
except in compliance with all securities laws. Subject to the above, this
Warrant Agreement and the Warrants are transferable in the same manner and with
the same effect as in the case of a negotiable instrument payable to a
specified person.  The Company, however, may treat the registered holder
thereof as the owner hereof for all purposes until the Warrant Certificate is
surrendered for transfer as hereinafter provided.  Upon surrender of the
Warrant Certificate at the principal office of the Company, together with a
written assignment thereof duly executed by the holder hereof or his agent or
attorney, the Company shall execute and deliver a new Warrant Certificate in
the name of the assignee or assignees and in the denominations specified in
such instrument of assignment.  The Company shall pay all expenses, taxes and
other charges payable in connection with the preparation, execution and
delivery of Warrant Certificate under this section, except that in case such
new Warrant





                                      A-2
<PAGE>   39





is registered in a name or names other than the name of the holder of this
Warrant Agreement all stock transfer taxes payable upon the execution and
delivery of such Warrant Certificate shall be paid by the holder hereof at the
time of the presentation thereof.  In such case the holder hereof shall deliver
at the time of such presentation evidence, satisfactory to the Company, that
such taxes have been paid.

         7.      Registration Under the Securities Act of 1933.  Neither the
Warrants nor the shares of Common Stock issuable upon exercise of the Warrants
have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), or any applicable state securities or blue sky laws.  Upon
exercise of the Warrants, the Company may cause a legend in substantially the
form set forth below to be placed on each certificate representing the shares
of Common Stock issued.

                 The shares of stock represented by this certificate have not
                 been registered under the Securities Act of 1993, as amended
                 (the "Securities Act"), for public resale and may not be
                 offered, transferred or sold except pursuant to (i) an
                 effective registration statement under the Securities Act and
                 any applicable state securities or blue sky laws, (ii) to the
                 extent applicable, Rule 144 under the securities act (or any
                 similar rule under the securities act relating to the
                 disposition of securities) together with an opinion of counsel
                 reasonably satisfactory to issuer's counsel that such transfer
                 is permitted or (iii) an opinion of counsel reasonably
                 satisfactory to issuer's counsel that an exemption from
                 registration under the securities act and any applicable state
                 securities or blue sky laws is available.


         8.      Adjustments to Exercise and Number of Securities.

                 8.1      Recapitalization and Reclassifications.  If  upon a
recapitalization or reclassification the shares of Common Stock are changed
into or become exchangeable for a larger or smaller number of shares, then upon
the effective date thereof the number of shares of Common Stock that Holder
shall be entitled to purchase upon exercise of the Warrants shall be increased
or decreased, as the case may be, in direct proportion to the increase or
decrease in the number of shares of Common Stock by reason of such
recapitalization or reclassification, and the Exercise Price shall be, in the
case of an increase in the number of shares, proportionately decreased and, in
the case of a decrease in the number of shares, proportionately increased.





                                      A-3
<PAGE>   40





                 8.2      Sale; Merger; Consolidation.  Subject to the notice
provisions set forth in section 13, upon a transfer or sale of all or
substantially all the capital stock or assets of the Company or in the case of
any consolidation or merger of the Company with another entity (other than a
consolidation or merger that does not result in any reclassification or change
of the outstanding Common Stock), the transferee, purchaser or entity formed by
or surviving the consolidation or merger, as the case may be, shall execute and
deliver to Holder a supplemental warrant agreement giving Holder the right
during the Exercise Period to receive, upon exercise of the Warrants, the kind
and amount of shares of stock and/or other securities receivable upon such
transfer, sale, consolidation or merger, as the case may be, by a holder of the
number of shares of Common Stock for which such Warrants could have been
exercised immediately prior to such transfer, sale, consolidation or merger. If
such transfer, sale, consolidation or merger results in the shareholders of the
Company receiving cash or publicly traded securities having a value in excess
of the Exercise Price, this Warrant Agreement shall terminate if not exercised
prior to the closing date of such transaction.  Such supplemental warrant
agreement shall provide for adjustments identical to the adjustments provided
in this section 8.

                 8.3      No Adjustment of Exercise Price in Certain Cases.  No
adjustment of the Exercise Price shall be made if the amount of an adjustment
is less than $.02 per share of Common Stock provided that any adjustment that
would otherwise be required then to be made shall be carried forward and shall
be made at the time of and together with the next subsequent adjustment that,
together with any such adjustment, amounts to at least $.02 per share of Common
Stock.

                 8.4      Dividends and Other Distributions.    If the Company
declares a dividend payable in shares of Common Stock, Holder shall be entitled
to receive upon exercise of the Warrant, in addition to the number of shares of
Common Stock as to which the Warrant is exercised, such additional shares of
Common Stock as Holder would have received had the Warrant been exercised
immediately prior to such record date for the dividend.  If the Company
declares a dividend of securities other than a dividend of Common Stock, Holder
shall thereafter be entitled to receive upon the exercise of such Warrants in
addition to the shares of Common Stock receivable upon the exercise





                                      A-4
<PAGE>   41





of such Warrants, such non-Common Stock dividend as Holder would have received
had the Warrant been exercised immediately prior to such record date for the
dividend. At the time of any such dividend or distribution, the Company shall
make appropriate reserves to ensure the timely performance of this section 8.
Holder shall not be entitled to receive any cash dividend declared by the
Company.

                 8.5      If the Company issues in a public offering any shares
of Common Stock for a consideration per share less than the prevailing Exercise
Price, then (a) the Exercise Price in effect immediately prior to each such
instance shall be adjusted to a price equal to the quotient obtained by
dividing (i) an amount equal to the sum of the total number of shares of Common
Stock outstanding on a fully diluted basis immediately prior to such issuance
multiplied by the Exercise Price in effect immediately prior to such issuance
(the "Old Common Stock Number"), plus  the consideration received by the
Company upon such issuance, by (ii) the total number  of shares of Common Stock
outstanding on a fully diluted basis immediately after such issuance (the "New
Common Stock Number"), and (b) the number of shares of Common Stock then
issuable upon the exercise of the Warrants outstanding immediately prior to
each such issuance shall forthwith be adjusted by multiplying such number so
issuable by the quotient obtained by dividing (i) the New Common Stock Number
by (ii) the Old Common Stock Number.

                 8.6      Except as provided in section 8.5, if the Company
issues shares of Common Stock, or convertible preferred stock, warrants,
options, rights, or other securities only to the extent the aforementioned
securities are convertible into or exchangeable or exercisable for shares of
Common Stock, or rights to subscribe for or to purchase Common Stock or any
stock or securities convertible into or exchangeable or exercisable for Common
Stock, without consideration or for a consideration per share less than the
prevailing Exercise Price then, the Exercise Price in effect immediately prior
to each such issuance shall be decreased and the number of shares of Common
Stock issuable upon the exercise of the Warrants shall be increased pursuant to
the formula set forth in section 8.5 counting as consideration received by the
Company the consideration actually received plus that deemed to be received
upon such conversion or exchange as provided in section 8.7(c).





                                      A-5

                 8.7      For the purposes of any adjustment of the Exercise
Price and the number of shares of Common Stock issuable upon exercise of the
Warrants pursuant to sections 8.5 and 8.6, the following provisions shall be
applicable:

                          (a)     In the case of the issuance of Common Stock
                 for cash, the consideration shall be deemed to be the amount
                 of cash received by the Company therefor.

                          (b)     In the case of the issuance of Common Stock
                 for a consideration in whole or in part other than cash, the
                 consideration other than cash shall be deemed to be the "fair
                 value" of such consideration as determined in the good faith
                 judgment of the board of directors of the Company.

                          (c)     In the case of the issuance of (x) options to
                 purchase or rights to subscribe for Common Stock, (y)
                 securities by their terms convertible into or exchangeable for
                 Common Stock or (z) options to purchase or rights to subscribe
                 for such convertible or exchangeable securities:

                                  (i)      the aggregate maximum number of
                          shares of Common Stock deliverable upon exercise of
                          such options to purchase or rights to subscribe for
                          Common Stock shall be deemed to have been issued at
                          the time such options or rights were issued and for a
                          consideration equal to the consideration (determined
                          in the manner provided in subsections (a) and (b)
                          above), if any, received by the Company upon the
                          issuance of such options or rights plus the minimum
                          purchase price provided in such options or rights for
                          the Common Stock covered thereby;

                                  (ii)     the aggregate maximum number of
                          shares of Common Stock deliverable upon conversion of
                          or in exchange for any such convertible or
                          exchangeable securities or upon the exercise of
                          options to purchase or rights to subscribe for such
                          convertible or exchangeable securities and subsequent
                          conversion or exchange thereof shall be deemed to
                          have been issued at the time such securities were
                          issued or such options or rights were issued and for
                          a consideration equal to the consideration received
                          by the Company for any





                                      A-6
<PAGE>   43





                          such securities and related options or rights
                          (excluding any cash received on account of accrued
                          interest or accrued dividends), plus the additional
                          consideration, if any, to be received by the Company
                          upon the conversion or exchange of such securities or
                          the exercise of any related options or rights (the
                          consideration in each case to be determined in the
                          manner provided in subsections (a) and (b) above);

                                  (iii)    on any change in the number of
                          shares or exercise price of Common Stock deliverable
                          upon exercise of any such options or rights or
                          conversions of or exchange for such convertible or
                          exchangeable securities, other than a change
                          resulting from the antidilution provisions thereof,
                          the Exercise Price and the number of shares of Common
                          Stock issuable upon exercise of the Warrants shall
                          forthwith be readjusted to such Exercise Price and to
                          such number of shares as would have obtained had the
                          adjustment made at the time of the issuance of such
                          options, rights or securities not converted prior to
                          such change been made upon the basis of such change;
                          and

                                  (iv)     on the expiration of any such option
                          or rights, the termination of any such rights to
                          convert or exchange or the expiration of any options
                          or rights related to such convertible or exchangeable
                          securities, the Exercise Price and the number of
                          shares of Common Stock issuable upon exercise of the
                          Warrants shall forthwith be readjusted to such
                          Exercise Price and to such number of shares as would
                          have obtained had such options, rights, securities or
                          options or rights related to such securities not been
                          issued.

                 8.8      Definition of Common Stock. The term "Common Stock"
shall mean:

                          (a)      the class of stock designated as Common
         Stock in the Company's Articles of Incorporation, as may be amended,
         or any other class of stock resulting from successive changes or
         reclassifications of such Common Stock; and





                                      A-7
<PAGE>   44





                          (b)      if, as a result of an adjustment made 
         pursuant to this section 8, Holder shall upon exercise of the Warrants
         become entitled to receive securities or assets other than Common Stock
         then, wherever appropriate, all references herein to shares of Common
         Stock shall be deemed to refer to and include such other securities or
         assets and thereafter the number of such other securities or assets
         shall be subject to adjustment from time to time in a manner and upon
         terms as nearly equivalent as practicable to the provisions of this
         section

         9.      Issuance of New Warrant Certificate.  Upon receipt by the
Company of evidence reasonably satisfactory to it of a loss, theft, destruction
or mutilation of a Warrant Certificate, reimbursement by Holder to the Company
of all incidental expenses and, in the case of loss, theft or destruction,
receipt of indemnity or security from Holder reasonably satisfactory to it or,
in the case of a mutilated Warrant Certificate, upon surrender and cancellation
thereof, the Company shall  make and deliver a new Warrant Certificate to
Holder.

         10.     Elimination of Fractional Interests.  The Company shall not be
required to issue certificates representing fractions of shares of Common Stock
upon the exercise of the Warrants.  The Company shall have the option to make
payment in cash in respect of any fractional shares or to round any fraction up
to the nearest whole number of shares of Common Stock.

         11.     Reservation and Listing of Securities.  The Company shall at
all times reserve and keep available out of its authorized shares of Common
Stock, solely for the purpose of issuance upon the exercise of the Warrants,
such number of shares of Common Stock as shall be issuable upon the exercise
thereof. The Company covenant and agrees that, upon exercise of the Warrants
and payment of the Exercise Price by Holder, all shares of Common Stock
issuable upon such exercise shall be duly and validly issued, fully paid and
non-assessable.

         12.     Representations and Warranties.

                 12.1     Holder represents and warrants to the Company that
the Warrants are being acquired solely for Holder's own account, for
investment, not for the interest of any other and are not being acquired with a
view to





                                      A-8
<PAGE>   45





or for resale, distribution, assignment, subdivision or fractionalization
thereof, and Holder has no present plan to enter into any contract,
undertaking, agreement or arrangement for such purpose.

                 12.2     Holder represents and warrants to the Company that it
is an "Accredited investor" and a "sophisticated investor," each as defined in
the Regulation D promulgated under the Securities Act.

         13.     Advance Notice to Warrant Holder re: Dividend, Exchange,
Merger, etc.  Nothing contained in this Warrant Agreement shall be construed as
conferring upon Holder the right to vote, consent or receive notice as a
stockholder in respect of any meeting of stockholders for the election of
directors or any other matter, or as having any right  as a stockholder of the
Company.  If, however, at any time prior to the expiration of the Warrants and
their exercise, any of the following events shall occur:

                          (a)  the Company takes a record of the holders of its
         shares of Common Stock for the purpose of entitling them to receive a
         dividend or distribution payable other than in cash, or a cash
         dividend or distribution payable otherwise than out of current or
         retained earnings, as indicated by the accounting treatment (which
         treatment shall be in accordance with generally accepted accounting
         principles) of such dividend or distribution on the books of the
         Company; or

                          (b)  the Company offers to all the holders of its
         Common Stock any additional shares of capital stock of the Company or
         securities convertible into or exchange for shares of capital stock of
         the Company, or any option, right or warrant to subscribe therefor; or

                          (c)  a dissolution, liquidation, winding up,
         transfer, consolidation, merger or a sale of all or substantially all
         its property, assets and business as an entirety is proposed; the
         Company shall give notice of such event at least 15 days prior to the

         (b)     The Bionutrics Entities, individually and jointly, agree to

Bionutrics Entities and ACH hereby agree as follows with respect to their
respective rights and duties as to the Joint Subject Matter Patents:

                 (i)      ACH shall have the exclusive rights as to all claims
         that cover the ACH Field of Use.  The Bionutrics Entities shall have
         no right to grant any license, release, or immunity from suit as to
         the ACH Field of Use, and the Bionutrics Entities shall have no right
         to make, use, offer to sell, sell the patented invention within the
         ACH Field of Use or import the patented invention within the ACH Field
         of Use.  As to United States Patent No. 5,591,772, ACH and the

         includes claims 31, 32, 34, 35 and 39.





                                      D-3
<PAGE>   56





                 (ii)     ACH shall have the exclusive right to sue in the name
         of ACH (or if so required by the law of the forum, to bring suit in
         the name of one or all of the Bionutrics Entities or join one or all
         of the Bionutrics Entities as a party plaintiff with ACH) for all
         past, present, and future infringement, including damages, of such
         Joint Subject Matter Patents within the ACH Field of Use.  Whenever
         such suit is brought by ACH as provided above, ACH shall notify the
         Bionutrics Entities in writing of such suit.  The Bionutrics Entities
         shall have the right, in any such suit brought by ACH, to be
         represented at their own expense by counsel of their own selection;
         provided, however, that ACH shall have control over such suit and any
         settlement of such suit, except that ACH shall not enter into or agree
         to an order, consent judgment, or the like that invalidates any of the
         claims of the Joint Subject Matter Patents.  The Bionutrics Entities
         shall fully cooperate with ACH in the bringing of such suit, including
         making their employees available as needed for such suit.

                 (iii)    The Bionutrics Entities shall have the exclusive
         rights as to all claims that cover the Bionutrics Field of Use.  ACH
         shall have no right to grant any license, release, or immunity from
         suit as to the Bionutrics Field of Use, and ACH shall have no right to
         make, use, offer to sell, sell the patented invention within the
         Bionutrics Field of Use, or import the patented invention within the
         Bionutrics Field of Use.  As to the United States Patent No.
         5,591,772, ACH and the Bionutrics Entities agree that the Bionutrics
         Field of Use specifically includes claims 1 - 30, 33, and 36-38.

                 (iv)     The Bionutrics Entities shall have the exclusive
         right to sue in the name of the Bionutrics Entities (or if so required
         by the law of the forum, to bring suit in the name of ACH or join ACH
         as a party plaintiff with the Bionutrics Entities) for all past,
         present, and future infringement, including damages, of such Joint
         Subject Matter Patents within the Bionutrics Field of Use.  Whenever
         such suit is brought by the Bionutrics Entities as provided above, the
         Bionutrics Entities shall notify ACH in writing of such suit.  ACH
         shall have the right, in any such suit brought by the Bionutrics
         Entities, to be represented at its own expense by counsel of its own
         selection; provided, however, that the Bionutrics Entities shall have
         control over such suit and any settlement of such suit, except that
         the Bionutrics Entities shall not enter into or agree to an order,
         consent judgment, or the like which invalidates any of the claims of
         the Joint Subject Matter Patents.  ACH shall fully cooperate with the
         Bionutrics Entities in the bringing of such suit, including making
         employees available as needed for such suit.

                 (v)      In the event that a suit involves issues as to both
         the ACH Field of Use and the Bionutrics Field of Use, both parties
         shall have the right to control the litigation as to their specific
         Fields of Use.  In the event that a suit is filed under Section
         2(b)(i) - (iv), the party not controlling the suit shall have no
         financial responsibility for the suit beyond the expense of its own
         counsel.

         lecithin, waxes, rice bran protein, Rice Bran Oil Distillates or any
         other rice-derived products produced by ACH or its Affiliates using
         the Joint Subject Matter Patents or Intellectual Property,

         waxes, rice bran protein, Rice Bran Oil Distillates or any other
         rice-derived products without claims and causes of action asserted by
         the Bionutrics Entities.

                 (iv)     If a third party acquires such rice bran oil,
         lecithin, waxes, rice bran protein, Rice Bran Oil Distillates or any
         other rice-derived products produced by ACH or its Affiliates and such
         third party either modifies or uses such rice bran oil, lecithin,
         waxes, rice bran protein, Rice Bran Oil Distillates or any other
         rice-derived products in such a way that it infringes the Bionutrics
         Entities Field of Use, then the Bionutrics Entities shall have no
         claim, cause of action, or remedy against ACH or its Affiliates for
         inducing such alleged infringement or for ACH's sale of such rice bran
         oil, lecithin, waxes, rice bran protein, Rice Bran Oil

         Distillates or any other rice-derived products; provided, however, the
         Bionutrics Entities shall retain all rights and remedies against any
         third parties for such third party's allegedly infringing acts.

such Intellectual Property regarding stabilization processes, the Bionutrics
Entities shall disclose such Intellectual Property as set forth in Section 7

Entities shall file a patent application anywhere in the world without the
agreement of the other party.  As to any other Intellectual Property within the
scope of Sections 2(c) and (d) involving processing steps in the ACH Field of

         4.      REPRESENTATIONS AND WARRANTIES.   The Bionutrics Entities
represent and warrant that:

         (a)     the Bionutrics Entities are legally free to make and perform
this Agreement, that the Bionutrics Entities have no obligation to any other
person or entity that would affect or conflict with any of their obligations
hereunder, and that the complete performance of the Bionutrics Entities'
obligations hereunder will not violate any law, regulation, order or decree of
any governmental or judicial body or contract by which any of the Bionutrics
Entities is bound;

         (b)     the patents and patent applications listed on Exhibit 1 are
the only patents or patent applications for which the Bionutrics Entities own
or have filed, jointly or solely, that relate to the ACH Field of Use;

         (c)     the Bionutrics Entities have not transferred to any third
party, by assignment, mortgage, security interest, license, or otherwise, any
of the rights or title in and to any of the Intellectual Property; and

         (d)     the Bionutrics Entities have full legal and equitable title to
the Intellectual Property.

         5.      THE BIONUTRICS ENTITIES' COVENANT.

         (a)     The Bionutrics Entities, in order to induce ACH to enter into
this Agreement, expressly covenant and agree that during the Excluded Period,
the Bionutrics Entities will not, and the Bionutrics Entities will cause their
Affiliates not to, directly or indirectly, own, manage, operate, join, control
or participate in with any business, individual, partnership, firm or
corporation, which engages in any business that provides services within the
ACH Field of Use in North America.  As used in this Section 5, "Excluded
Period" shall mean the term of this Technology Agreement, but commencing only
upon the Closing Date of the transfer of assets pursuant to the Agreement for
Purchase and Sale of Assets.

         (b)     Notwithstanding the restrictions contained in Section 5(a),
the Bionutrics Entities or any of their Affiliates may own an aggregate of not
more than 2.5% of the outstanding stock of any class of any corporation engaged
in a business within the ACH Field of Use, if such stock is listed on a
national securities exchange or regularly traded in the over-the-counter market
by a member of a national securities exchange, without violating the provisions
of Section 5(a), provided that none of Sellers or their Affiliates have the
power, directly or indirectly, to control or direct the management or affairs
of any such corporation and are not involved in the management of such
corporation.

         (c)     The Bionutrics Entities further expressly covenant and agree
that for a period of two years from and after the Closing Date, the Bionutrics
Entities will not, and the Bionutrics Entities will cause their Affiliates not
to (1) engage or employ, or solicit or contact with a view to the engagement





                                      D-7
<PAGE>   60





or employment by any person who is (or in the twelve months prior to the
Closing Date has been) an officer or employee of NTC; or (2) canvass, solicit,
approach or entice away or cause to be canvassed, solicited, approached or
enticed away from ACH any person who or which is (or in the twelve months prior
to the Closing Date has been) a customer or client of NTC.

         (d)     To the extent that any part of this Section 5 may be invalid,
illegal or unenforceable for any reason, it is intended that such part shall be
enforceable to the extent that a court of competent jurisdiction shall
determine that such part, if more limited in scope, would have been
enforceable, and such part shall be deemed to have been so written and the
remaining parts shall as written be effective and enforceable in all events.

         (e)     The Bionutrics Entities and ACH agree and acknowledge that the
limitations as to time, geographical area and scope of activity to be
restrained as set forth in this Section 5 do not impose any greater restraint
than is necessary to protect the legitimate business interests of ACH.  The
Bionutrics Entities and ACH further agree and acknowledge that, in the event of
a breach or threatened breach of any of the provisions of this Section 5, ACH
shall be entitled to immediate injunctive relief, as any such breach would
cause ACH irreparable injury for which it would have no adequate remedy at law.
Nothing herein shall be construed so as to prohibit ACH from pursuing any other
remedies available to it hereunder, at law or in equity for any such breach or
threatened breach.

         (f)     The Bionutrics Entities hereby represent to ACH that they have
read and understand, and agree to be bound by, the terms of this Section.  The
Bionutrics Entities acknowledge that the geographic scope and duration of the
covenants contained in this Section are the result of arm's-length bargaining
and are fair and reasonable in light of (i) the nature and wide geographic
scope of the operations of NTC, (ii) the Bionutrics Entities' level of control
over and contact with NTC business and operations in all jurisdictions where
same are conducted, (iii) the fact that the NTC business is conducted
throughout the geographic area where competition is restricted by this
Agreement, and (iv) the amount of consideration that the Bionutrics Entities
are receiving in connection with the Agreement and the amount of the goodwill
for which ACH is paying.  It is the desire and intent of the parties that the
provisions of this Agreement be enforced to the fullest extent permitted under
applicable law, whether now or hereafter in effect and therefore, to the extent
permitted by applicable law, the parties hereto waive any provision of
applicable law that would render any provision of this Section 5 invalid or
unenforceable.

         (g)     From and after the Effective Date of this Agreement, none of
the Bionutrics Entities will directly or indirectly use in any manner any trade
name, trademark, service mark or logo listed on Exhibit 4 or any word or logo
that is similar in sound or appearance.

         6.      ACH'S COVENANT.

         (a)     ACH, in order to induce The Bionutrics Entities to enter into
this Agreement, expressly covenants and agrees with Bionutrics that during
Excluded Period, ACH will not, and ACH will cause their Affiliates not to,
directly or indirectly, own, manage, operate, join, control or participate in
with





                                      D-8
<PAGE>   61





any business, individual, partnership, firm or corporation, other than the
Bionutrics Entities, which engages in any business that markets or sells
Clearesterol in North America.  As used in this Section, "Excluded Period"
shall mean the time period during which the claims of the United States Patent
No. 5,591,772 covering the marketing and sale of Clearesterol (and not methods
for its use) remain valid and enforceable but in no event shall the Excluded
Period extend beyond the term of this Technology Agreement. In addition, the
Excluded Period shall commence upon the Closing Date of the transfer of assets
pursuant to  the Agreement for Purchase and Sale of Assets.  The covenant is
this Section 6 shall only run in favor of Bionutrics and shall not be
assignable or transferable to a third party.

         (b)     Notwithstanding the restrictions contained in Section 6(a),
ACH or any of its Affiliates may own an aggregate of not more than 2.5% of the
outstanding stock of any class of any corporation (other than the Bionutrics
Entities) engaged in a business that markets or sells Clearesterol in North
America, if such stock is listed on a national securities exchange or regularly
traded in the over-the-counter market by a member of a national securities
exchange, without violating the provisions of Section  6(a) provided that none
of ACH or its Affiliates have the power, directly or indirectly, to control or
direct the management or affairs of any such corporation and are not involved
in the management of such corporation.

         (c)     To the extent that any part of this Section may be invalid,
illegal or unenforceable for any reason, it is intended that such part shall be
enforceable to the extent that a court of competent jurisdiction shall
determine that such part, if more limited in scope, would have been
enforceable, and such part shall be deemed to have been so written and the
remaining parts shall as written be effective and enforceable in all events.

         (d)     ACH agrees and acknowledge that the limitations as to time,
geographical area and scope of activity to be restrained as set forth in this
Section 6 do not impose any greater restraint than is necessary to protect the
legitimate business interests of the Bionutrics Entities.  ACH further agrees
and acknowledges that, in the event of a breach or threatened breach of any of
the provisions of this Section 6, the Bionutrics Entities shall be entitled to
immediate injunctive relief, as any such breach would cause the Bionutrics
Entities irreparable injury for which it would have no adequate remedy at law.
Nothing herein shall be construed so as to prohibit the Bionutrics Entities
from pursuing any other remedies available to it hereunder, at law or in equity
for any such breach or threatened breach.

         (e)     ACH hereby represents to the Bionutrics Entities that it has
read and understands, and agrees to be bound by, the terms of this Section 6.
ACH acknowledges that the geographic scope and duration of the covenants
contained in this Section 6 are the result of arm's-length bargaining and are
fair and reasonable in light of  the nature and wide geographic scope of the
operations of ACH, (ii) ACH's level of contact with the business and operations
of Bionutrics Entities in all jurisdictions where same are conducted, (iii) the
fact that the ACH business is conducted throughout the geographic area where
competition is restricted by this Agreement, and (iv) ACH's access to
Bionutrics Intellectual Property, including Trade Secrets, granted in this
Agreement.  It is the desire and intent of the parties that the provisions of
this Agreement be enforced to the fullest extent permitted under applicable
law, whether now or hereafter in effect and therefore, to the extent permitted
by applicable law, the parties hereto waive any provision of applicable law
that would render any provision of this Section 6 invalid or unenforceable.

         7.      FURTHER ACTS AND COOPERATION.  At the request of ACH, the
Bionutrics Entities, individually or jointly as may be requested by ACH, shall
execute any and all papers and perform all lawful acts that ACH may deem
necessary or appropriate to further evidence or carry out the transactions
contemplated in this Agreement including, without limitation, such acts as may
be necessary for the preparation, filing, prosecution, and maintenance of
applications for United States letters patent and foreign letters patent, the
assignment of United States letters patent and foreign letters patent
(including but not limited to those patents identified on Exhibit 1 and
assigned under Section 2(a)), or for United States and foreign copyright, on
the Intellectual Property.  The Bionutrics Entities shall also assist and fully
cooperate in every way, at ACH's expense, in securing, maintaining, and
enforcing, for the benefit of ACH or its designee, patents, copyrights or other
types of proprietary or intellectual property protection for the Intellectual
Property in any and all countries.  In addition, the Bionutrics Entities shall
disclose and provide to ACH all documents bearing, embodying or disclosing the
Intellectual Property so as to allow ACH to practice and protect such
Intellectual Property.  With respect to Intellectual Property within the scope
of Sections 2(c) and (d), the Bionutrics Entities shall make disclosures of the
current status and details of any such Intellectual Property, including any
projects, developments, or research within the ACH Field of Use, every six
months.  These disclosures shall take place in status meetings to be scheduled
by ACH.  ACH shall notify the Bionutrics Entities of such status meetings.  If
no status meeting takes place for six months  or longer because ACH fails to
schedule such meetings, the Bionutrics Entities will not be in default of this
provision.  Once ACH notifies that no status meeting has taken place for six
months, the next status meeting shall take place promptly but no later than
thirty (30) days  after such notice.

         8.      RESTRICTIONS ON TRADE SECRETS AND CONFIDENTIAL INFORMATION.

         (a)     During the term of this Agreement and thereafter, each of the
Bionutrics Entities agrees not to disclose to others, use, copy or permit to be
copied, except with the express written approval of ACH, its successors,
assigns or nominees, any of the Trade Secrets assigned hereunder without the
prior written consent of ACH.

         (b)     As to disclosures by the Bionutrics Entities of Intellectual
Property involving processing steps in the ACH Field of Use after stabilization
up to and through deodorization described in Section 2(f) and as to any
disclosures by ACH of confidential information or trade secrets regarding the
ACH Field of Use other than the Trade Secrets or developed, conceived, reduced
to practice, or acquired, whether by purchase or license, by ACH or its
Affiliates during the term of this Agreement, (collectively referred to in this
Section 8 as "Confidential Information"):

         (i)     ACH and the Bionutrics Entities agree to hold such
Confidential Information owned by the other party in the strictest confidence
and shall exercise due care to prevent the unauthorized disclosure of such
information or its use for any unauthorized purpose.

<PAGE>   63





         (ii)    ACH and the Bionutrics Entities shall only disclose the
Confidential Information of the other party to their employees and officers
(and consultants, attorneys, and accountants) who have a need to have access to
such for the purposes of this Agreement, but shall not disclose the same to any
employee or officer who may use such for any other purpose. ACH and the
Bionutrics Entities shall require each employee and officer who is granted
access to such information to agree to abide by the terms of this Section 8.

         (iii)   ACH and the Bionutrics Entities agree that such Confidential
Information and any developments materially derived therefrom are and shall
remain the sole property of the party disclosing such Intellectual Property
(the "Disclosing Party") or the party owning such Intellectual Property in the
case of Intellectual Property acquired by ACH pursuant to Section 2(f)) .

         (iv)    Confidential Information shall exclude information that:

                 (1)      is disclosed in a printed or online publication
         available to the public, is described in an issued patent anywhere in
         the world, is otherwise in the public domain at the time of
         disclosure, or becomes publicly known through no wrongful act on the
         part of the party (or its Affiliates) receiving the Confidential
         Information  (the "Receiving Party");

                 (2)      is already known to the Receiving Party at the time
         of the disclosure or becomes known to or lawfully available to the
         Receiving Party through disclosure by a third party who has not
         received the Confidential Information, directly or indirectly, from
         the Disclosing Party under an obligation of secrecy;

                 (3)      is disclosed to third parties by the Disclosing Party
         without an obligation of confidence being imposed on such third
         parties;

                 (4)      is subsequently developed by or for the Receiving
         Party without use of the Confidential Information by the Disclosing
         Party; and

                 (5)      the Disclosing Party expressly authorizes in writing
         shall not be considered Confidential Information.

         (v)     If a Disclosing Party discloses information it believes is
Confidential Information, the Disclosing Party shall specifically designate
materials bearing the confidential information "CONFIDENTIAL."  If a Disclosing
Party discloses orally to the Receiving Party information the Disclosing Party
believes is confidential, the Disclosing Party shall within thirty days of such
disclosure reduce such information to writing and provide such writing to the
Receiving Party marked CONFIDENTIAL.

<PAGE>   64





         (f)     If any portion of Confidential Information is required to be
disclosed to a governmental regulatory agency or commission, or is otherwise
required to be disclosed by law or regulation, subpoena, civil investigative
demand or similar process, the Receiving Party will inform the Disclosing Party
of such disclosure requirement as soon as practicable after notice of such
requirement is received and will further inform the Disclosing Party which
Confidential Information is required to be disclosed.  The Disclosing Party
shall then be completely responsible for seeking any protective order to
protect the confidentiality of the Confidential Information.  In the event that
the Disclosing Party is unable to obtain a protective order satisfactory to the
Disclosing Party, after the exhaustion of all applications for writs of
mandamus and all interlocutory appeals from the denial of such a protective
order, the Receiving Party shall have the right to disclose the specific
Confidential Information that is required to be disclosed in the particular
proceeding.

         9.      ENTIRE AGREEMENT.  This Agreement sets forth the entire
agreement and understanding between the parties as to the subject matter of
this Agreement and supersedes all prior discussions between them, and neither
of the parties shall be bound by any modification of this Agreement, other than
as expressly provided in this Agreement or as duly set forth on or subsequent
to the date hereof in writing and signed by a duly authorized representative of
the party to be bound thereby.  No oral explanation or oral information by
either party hereto shall alter the meaning or interpretation of this
Agreement. This Agreement incorporates the entire agreement of the parties with
respect to the subject matter hereof and supersedes all prior agreements,
documents, or other instruments with respect to the matters covered hereby.
The failure of either party to enforce at any time any provision of this
Agreement shall not be construed as a waiver of such provision.  Neither shall
the waiver by either party of a breach by the other party of any provision of
this Agreement constitute a continuing waiver of other breaches of the same
provision or a waiver of any breach of any other provision of this Agreement.

         10.     ASSIGNMENT.  The obligations of this Agreement shall be binding
upon the parties hereto, their successors, assigns, and legal representatives.
This Agreement shall only be assignable or transferable by either ACH or the
Bionutrics Entities in connection with a merger or a sale of all or
substantially all of the assets of a party to which this Agreement relates;
provided, however, ACH may assign this Agreement any or all to its Affiliates;
and provided further, the sale or transfer of substantially all of the business
of ACH related to the Intellectual Property shall be deemed to constitute a sale
of all or substantially all of the assets of ACH for purposes of satisfying the
provisions of this Section 10.  In the event of such an assignment or transfer,
the assignor or transferor shall advise the assignee or transferee of the
existence of this Agreement and the obligations hereunder, and such assignee or
transferee to whom such assignment or transfer has been made shall
unconditionally and without restriction expressly assume and succeed in writing
to all obligations and rights of the assigning party or parties under this
Agreement from and after the date thereof or from and after the date thereof by

obligations and rights and shall provide a copy of such agreement to the other
party or parties to this Agreement.  Except as set forth in this Agreement, this
Agreement shall not be assignable by any party hereto without the express
written consent of the other parties hereto.  Nothing in this Agreement shall be
construed as prohibiting ACH from transferring, assigning, licensing or





                                      D-12

sublicensing any or all of its rights in and to the Intellectual Property that

         11.     SEVERABILITY.    Should any clause, sentence, term or
paragraph of this Agreement be declared by a court of competent jurisdiction to
be invalid, unenforceable, or void, such decision shall not have the effect of
invalidating or voiding the remainder of this Agreement, and the parties hereto
hereby agree that the part or parts of this Agreement so held to be invalid,
unenforceable, or void shall be deemed to have been stricken, and the remainder
of this Agreement shall have the same force and effect as if such part or parts
had never been included herein.

         12.     TERM.    This term of this Agreement shall become effective on
the Effective Date and shall remain in effect throughout the life of the
Patents and such Patents as may be granted from any applications assigned under

3.       SUPPLY, PRODUCTION AND SHIPPING.

A.       During the Term, but only after the Commissioning Date and subject to
Section 10:

         (i)     BIONUTRICS DISTILLATE PRODUCTS.  Humko will sell and deliver
                 to Bionutrics, and Bionutrics will purchase and take from
                 Humko, all of Bionutrics' requirements for the Bionutrics

                 Price for Bionutrics Distillate Products shall be set
                 according to Exhibit A.

         (ii)    RICE BRAN PRODUCTS.  In the event that Bionutrics desires to
                 obtain any Rice Bran Product for any Bionutrics Product during
                 the Term of this Agreement, Bionutrics shall first offer to
                 Humko the right to supply all of Bionutrics' requirements for
                 such Rice Bran Product for any such Bionutrics Product.  This
                 right of first refusal shall operate as set forth in this
                 Section 3.A.(ii):

                 (a)      If, after Humko and Bionutrics discuss Humko's
                 supplying of requirements of such Rice Bran Product to
                 Bionutrics for such Bionutrics Products, Humko is willing and
                 able to supply such Rice Bran Product to Bionutrics at Humko's
                 market price and terms established by Humko from time to time,
                 then Bionutrics shall be obligated to take its requirements
                 from Humko for such Rice Bran Product unless Bionutrics is
                 able to obtain such Rice Bran Product requirements from a
                 third party at a better price and terms than the market price
                 and terms offered by Humko provided that there is no
                 pre-existing contract between Humko and Bionutrics with
                 respect to such Rice Bran Product.  If a third party offers a
                 better price and terms, Humko shall have thirty (30) days to
                 match such price and terms.  If Humko fails to do so within
                 such thirty (30) day period, then Bionutrics shall be free to
                 contract with such third party for its requirements of such
                 Rice Bran Product; provided, however, the terms and provisions
                 of Section 3.A.(ii)(c) shall be applicable to such Rice Bran
                 Product.  If Humko notifies Bionutrics that it will match such
                 price and terms within such period, then Humko will sell and
                 deliver to Bionutrics, and Bionutrics will purchase and take
                 from Humko, all of Bionutrics' requirements for the Rice Bran
                 Product for such Bionutrics Product upon such price and terms.

<PAGE>   77




                 (b)      If, after Humko and Bionutrics discuss Humko's
                 supplying of requirements of such Rice Bran Product to
                 Bionutrics, Humko is unwilling or unable to supply such Rice
                 Bran Product to Bionutrics at Humko's established market price
                 and terms, then Bionutrics shall be free to contract with such
                 third party for its requirements of such Rice Bran Product and
                 Bionutrics shall no longer owe Humko any obligation with
                 respect to Bionutrics' requirements for such Rice Bran
                 Product.

                 (c)      In contracting with such third party for its
                 requirements of such Rice Bran Product, this Agreement shall
                 not be construed to grant to Bionutrics or any such third
                 party, and Humko expressly negates and reserves, any rights to
                 use any of the Intellectual Property in North America with
                 respect to the processing of, or providing of, any Rice Bran
                 Product to Bionutrics.  Bionutrics expressly covenants not to
                 use in North America the Intellectual Property with respect to
                 any Rice Bran Product.

         (iii)   RICE BRAN OIL DISTILLATE THROUGH AUGUST 31, 2000.  For the
                 period from the Commissioning Date through August 31, 2000,
                 Humko will sell and deliver to Bionutrics, and Bionutrics will
                 purchase and take from Humko, all of Humko's entire output of
                 Rice Bran Oil Distillate, provided that the Rice Bran Oil
                 Distillate has a total Tocol content of at least 3%.  The
                 price for the Rice Bran Oil Distillate referred to in this
                 Section 3.A(iii) shall be as shown on Exhibit D.

         (iv)    RICE BRAN OIL DISTILLATE AFTER AUGUST 31, 2000.  If Humko and
                 Bionutrics have not voluntarily reached an agreement in
                 writing signed by both parties by August 31, 1999 regarding
                 the price and conditions for the supply of Rice Bran Oil
                 Distillate to Bionutrics after August 31, 2000, then Humko
                 shall be free to supply such Rice Bran Oil Distillate to third
                 parties on any terms and conditions that are more favorable to
                 Humko than those offered by Bionutrics.  If a third party or
                 third parties offer more favorable terms and conditions for
                 any or all of Humko's supply of the Rice Bran Oil Distillate,
                 Bionutrics shall have fourteen (14) days to match any such
                 terms and conditions by written notice to Humko.  If
                 Bionutrics fails to do so within such fourteen (14) day
                 period, then Humko shall be free to contract with such third
                 party or third parties for the supply of Rice Bran Oil
                 Distillate and Humko shall no longer owe Bionutrics any
                 obligation with respect to the supply of Rice Bran Oil
                 Distillate.  If Bionutrics matches the more favorable terms
                 and conditions offered by such third party, as set forth
                 above, then Humko will sell and deliver to Bionutrics, and
                 Bionutrics will purchase and take from Humko, all of Humko's
                 supply of the Rice Bran Oil Distillate to the extent and on
                 the terms and conditions set forth in such third-party offer.
                 To the extent that Bionutrics cannot obtain its requirements
                 of Rice Bran Oil Distillate after August 31, 2000 from Humko,
                 Humko grants to Bionutrics a limited, nonexclusive,
                 nontransferable





                                      E-5
<PAGE>   78



                 license to use the Intellectual Property  to import Rice Bran
                 Oil Distillate  from outside North America but only to produce
                 Derivative Products in Bionutrics' own facilities (or the
                 facilities of its subsidiaries and Affiliates).  This
                 Agreement shall not be construed to grant to Bionutrics or any
                 other party, and Humko expressly negates and reserves, any
                 rights to use any of the Intellectual Property with respect to
                 the production of Rice Bran Oil Distillate.  Bionutrics
                 expressly covenants not to use the Intellectual Property to
                 produce the Rice Bran Oil Distillate in North America.

         (v)     DERIVATIVE PRODUCTS AFTER AUGUST 31, 2000.  In the event that
                 Humko is no longer willing or able to supply all of its
                 production of Rice Bran Oil Distillate to Bionutrics, and
                 Humko is processing any or all of such Rice Bran Oil
                 Distillate into Derivative Products, Humko shall have the
                 option to supply Bionutrics with Bionutrics' needs for
                 Derivative Products.  Price to Bionutrics for Derivative
                 Products will be the market price for Rice Bran Oil Distillate
                 plus a toll processing fee.  Such toll processing fee will be
                 determined by two experts, one each selected by Humko and
                 Bionutrics, but in the event that the two experts so chosen
                 cannot agree, the toll processing fee shall be determined by a
                 third expert chosen jointly by the former two experts.  Humko
                 reserves the right to market any or all of its Rice Bran Oil
                 Distillate and Derivative Products to third parties.

         (vi)    It is understood that prior to the date hereof, Bionutrics may
                 have been purchasing or acquiring the Bionutrics Distillate
                 Products, Rice Bran Oil Distillate and Rice Bran Products from
                 other parties, but from and after the date hereof, Humko shall
                 be the exclusive supplier to Bionutrics of all Bionutrics
                 Distillate Products, Rice Bran Oil Distillate and Rice Bran
                 Products used by Bionutrics in the Bionutrics Products
                 (subject to any exclusions specified under Section 3.A.(i)-(v)
                 above); provided, however, until the Commissioning Date,
                 Bionutrics may continue to purchase or acquire the Bionutrics
                 Distillate Products, Rice Bran Oil Distillate, and Rice Bran
                 Products from other parties to fulfill its production
                 requirements in accordance with its normal course of business.
                 Notwithstanding the foregoing, Bionutrics may not enter into
                 any long term contracts for the supply of Bionutrics
                 Distillate Products, Rice Bran Oil Distillate, or Rice Bran
                 Products if the end of the term of any such contracts occurs
                 after January 1, 1999, except as provided in Section 10.

         B.      REQUIREMENTS PRIOR TO COMMISSIONING DATE.  Unless agreed
otherwise in writing, until the Commissioning Date, Humko shall have no
obligation to deliver the Bionutrics Distillate Products, Rice Bran Oil
Distillate, and Rice Bran Products.  Upon the occurrence of the Commissioning
Date, Humko will notify Bionutrics and begin supplying Bionutrics with its
requirements of Bionutrics Distillate Products, Rice Bran Oil Distillate and
Rice Bran Products





                                      E-6
<PAGE>   79



used by Bionutrics in the Bionutrics Products.  On or before the Commissioning
Date, Bionutrics will provide to Humko an initial order of its requirements of
Bionutrics Distillate Products, Rice Bran Oil Distillate and Rice Bran Products
used by Bionutrics in the Bionutrics Products for the time period prior to the
Commissioning Date (the "Initial Period").  This order shall contain all of the
terms set forth below in Section 3.D.

         C.      REQUIREMENTS AFTER COMMISSIONING DATE.

         (i)     (1) REQUIREMENTS OF BIONUTRICS DISTILLATE PRODUCTS.  By
January 15 of each calendar year during the Term of this Agreement, Bionutrics
shall notify Humko in writing with a good faith projection of its requirements
of Bionutrics Distillate Products for use in Bionutrics Products for the one
year period commencing on April 1 of the same calendar year (the "Applicable
One Year Period").  Such notification of requirements shall contain all of the
terms set forth below in Section 3.D.  By February 15 of the same calendar
year, Humko shall notify Bionutrics if Humko's capacity is insufficient to meet
such requirements.  In the event Humko so notifies Bionutrics, Bionutrics shall
be obligated to purchase Humko's capacity but as to Bionutrics' requirements in
excess of such capacity for that Applicable One Year Period, Humko grants to
Bionutrics a limited, nonexclusive, nontransferable license to use the
Intellectual Property in its own facilities solely to produce Bionutrics
Distillate Products but only using Bionutrics Distillate imported from outside
North America, which Bionutrics shall be permitted to import for this limited
purpose only.  This Agreement shall not be construed to grant to Bionutrics,
and Humko expressly negates and reserves, any rights to use any of the
Intellectual Property with respect to the production of Bionutrics Distillate
in North America.  Bionutrics expressly covenants not to use the Intellectual
Property with respect to the production of such Bionutrics Distillate in North
America.  If Humko notifies Bionutrics by March 15 of the same calendar year
that Humko can deliver all such requirements for the Applicable One Year
Period, then, unless otherwise agreed to in writing by Bionutrics, Humko shall
be obligated to, subject to Section 10, and will sell such requirements to
Bionutrics.  In addition, unless otherwise agreed to in writing by Humko,
Bionutrics shall be obligated to purchase its good faith projection of its
requirements of Bionutrics Distillate Products for the following calendar year
as set forth in the projection to the extent that Humko has obligated itself to
produce any of same in accordance with the foregoing provisions.  During the
Applicable One Year Period for which such requirements have been agreed upon by
Humko and Bionutrics pursuant to this Section 3.C.(i)(1) above, the parties
will work in good faith in the event that Bionutrics desires to modify the
original shipping and delivery dates for the quantities of the Bionutrics
Distillate Products ordered and required to be produced by Humko.

                 (2) REQUIREMENTS OF RICE BRAN PRODUCTS (PURSUANT TO SECTION 
3.A. (ii)(a)).  By January 15 of each calendar year during the Term of this
Agreement, Bionutrics shall notify Humko in writing with a good faith projection
of its requirements of Rice Bran Products, if any, for use in Bionutrics
Products for the Applicable One Year Period.  Such notification of





                                      E-7
<PAGE>   80
requirements shall contain all of the terms set forth below in Section 3.D. By
February 15 of the same calendar year, Humko shall notify Bionutrics if Humko's
capacity is insufficient to meet such requirements.  In the event Humko so
notifies Bionutrics, Bionutrics shall be obligated to purchase Humko's capacity
but as to Bionutrics' requirements in excess of such capacity for that
Applicable One Year Period, Bionutrics shall be free to contract with third
parties for its additional requirements of such Rice Bran Products that Humko is
unable to supply for that Applicable One Year Period, subject to the following
provisions of this Section 3.C.(i)(2). This Agreement shall not be construed to
grant to Bionutrics, and Humko expressly negates and reserves, any rights to use
any of the Intellectual Property with respect to the production of Rice Bran Oil
Distillate in North America.  Similarly, this Agreement shall not be construed
to grant to Bionutrics or any third party supplying Bionutrics with such Rice
Bran Products, and Humko expressly negates and reserves, any rights to use any
of the Intellectual Property with respect to the processing of such Rice Bran
Products for Bionutrics.  Bionutrics expressly covenants not to use the
Intellectual Property with respect to such Rice Bran Products in North America.
If Humko notifies Bionutrics by March 15 of the same calendar year that Humko
can deliver all such requirements for the Applicable One Year Period, then,
unless otherwise agreed to in writing by Bionutrics, Humko shall be obligated
to, subject to Section 10, and will sell such requirements to Bionutrics;
however, as to any additional capacity that Humko may have to produce any such
Rice Bran Products, Humko may freely contract to sell such additional capacity
to third parties for the Applicable One Year Period. In addition, unless
otherwise agreed to in writing by Humko, Bionutrics shall be obligated to
purchase its good faith projection of its requirements of Rice Bran Products for
the following calendar year as set forth in the projection to the extent that
Humko has obligated itself to produce any of same in accordance with the
foregoing provisions.  During the Applicable One Year Period for which such
requirements have been agreed upon by Humko and Bionutrics pursuant to this
Section 3.C.(i)(2) above, the parties will work in good faith in the event that
Bionutrics desires to modify the original shipping and delivery dates for the
quantities of any such Rice Bran Products ordered and required to be produced by
Humko.

         (ii)    If during any Applicable One Year Period, Bionutrics desires
to purchase additional amounts of the Bionutrics Distillate Products or Rice
Bran Products, Bionutrics shall notify Humko during the Applicable One Year
Period as set forth herein.  First, Bionutrics will notify Humko of Bionutrics'
anticipated needs for the Bionutrics Distillate Products and Rice Bran Products
in addition to its requirements previously set forth from time to time.
Without limiting the generality of the foregoing, Bionutrics will provide to
Humko, on a quarterly basis, and not later than the 15th day of the month
beginning each quarter during each Applicable One Year Period during the Term,
a good faith estimate of Bionutrics' anticipated additional needs (if any) of
the Bionutrics Distillate Products and Rice Bran Products for use in Bionutrics
Products during the remaining time in the Applicable One Year Period.  Although
Bionutrics' failure to provide such a quarterly estimate shall not be deemed a
breach of this Agreement, Humko shall have the right to offer any excess
capacity of Rice Bran Products for sale to third parties based on the last
estimate provided to Humko of Bionutrics' anticipated needs of Rice Bran
Products.  To the extent





                                      E-8
<PAGE>   81



Humko notifies Bionutrics that Humko can meet such additional annual or
quarterly requirements, then such orders shall become firm commitments as if
such orders had been originally included in the applicable order made pursuant
to Section 3.C.(i).

         D.      Each order for the Initial Period and the Applicable One Year
Periods shall specify the following minimum information: (i) the Bionutrics
Distillate Products, Rice Bran Oil Distillate, Derivative Products and Rice
Bran Products ordered, (ii) the quantities of the Bionutrics Distillate
Products, Rice Bran Oil Distillate, Derivative Products and Rice Bran Products
ordered, (iii) the delivery destination of each of the Bionutrics Distillate
Products, Rice Bran Oil Distillate, Derivative Products and Rice Bran Products
ordered if other than FOB the applicable Humko Plant, (iv) the shipment date
for the quantities of the Bionutrics Distillate Products, Rice Bran Oil
Distillate, Derivative Products and Rice Bran Products ordered (which shall not
be less than  thirty (30) working days from the applicable date of the purchase
order subject to Section 10), (v) the desired delivery date of each of the
Bionutrics Distillate Products, Rice Bran Oil Distillate, Derivative Products
and Rice Bran Products ordered, and (vi) special freight arrangements, if any,
which shall be at the sole cost and expense of Bionutrics.

         E.      Humko will deliver the Bionutrics Distillate Products, Rice
Bran Oil Distillate, Derivative Products and Rice Bran Products in amounts
necessary to fill all of Bionutrics' orders (subject to this Section 3 and
Section 10).  Unless specified otherwise on Bionutrics' orders, all deliveries
will be FOB the Humko Plants specified in Bionutrics' order.  Humko will
specify delivery of the Bionutrics Distillate Products, Rice Bran Oil
Distillate, Derivative Products and Rice Bran Products to designated Bionutrics
Plants via common carriers mutually acceptable to Bionutrics and Humko.
Bionutrics shall be responsible for all outbound freight costs.  Bionutrics
will instruct all agreed upon trucking companies to submit freight charges
directly to Bionutrics for payment.  Except with respect to the delivery
procedures for products covered in Exhibit E, Humko will arrange for all
transportation required to transport products shipped by Humko under this
Agreement to the applicable destination in accordance with the instructions
given by Bionutrics.  Humko will inform Bionutrics if Humko is unable to
arrange transportation with agreed upon trucking companies for any purchase
order and offer alternatives to Bionutrics if available.  Humko will provide
Bionutrics with adequate, timely shipping information.  Bionutrics shall be
responsible for tracking and managing freight from time of shipment to delivery
to the applicable destination.  Title to and risk of loss of all products
shipped by Humko under this Agreement shall transfer from Humko to Bionutrics
(or the applicable subsidiary and/or Affiliate of Bionutrics) at the time of
delivery at the applicable Humko Plant to the freight carrier designated in the
applicable purchase order.  If Bionutrics notifies Humko of discrepancies
between shipping and receiving weights or volume, the parties will negotiate in
good faith to determine appropriate corrective action and any adjustments
necessary to compensate Bionutrics for any shortages confirmed by such
discrepancies.

Bionutrics Products during the term of this Agreement, Humko shall have the
option, exercisable in its sole discretion, to provide any or all of the other
ingredients used in Bionutrics' production of other products produced by
Bionutrics.  If such other ingredients meet the specifications provided by
Bionutrics, such other ingredients shall be sold and delivered by Humko, and
purchased by Bionutrics, in accordance with the applicable terms of this
Agreement.  The price for such other ingredients shall be negotiated and agreed
to by Bionutrics and Humko prior to the sale of such ingredients by Humko to
Bionutrics.  Notwithstanding the foregoing, Bionutrics shall not be entitled to
purchase from any other supplier any products similar to the Bionutrics
Distillate Products, Rice Bran Oil Distillate, Derivative Products and Rice
Bran Products in order to fulfill the needs of Bionutrics except according to
the terms of Section 3.A.(ii) (Rice Bran Products), 3.A(iv) (Derivative
Products), 3.C(i) (Bionutrics Distillate Products and Rice Bran Products), or

<PAGE>   85



invoices containing invoicing errors, such dates, with respect to the incorrect
portions of the invoice only, are extended until the invoicing errors are
corrected and a new invoice, with respect to the incorrect portions on the
original invoice, is sent.

         C.      All payments required to be made under this Agreement shall
bear interest from the due date until paid at the rate per annum equal to the
lesser of (i) the maximum rate permitted by applicable law and (ii) (a) the
prime rate of interest published by the banking institution in which Humko has
deposited the most significant portion of its deposited funds plus five percent
(5%), or (b) fifteen percent (15%) per annum.

8.       QUALITY CONTROL.

         A.      As reasonably requested by Bionutrics, Humko will submit
samples of the Bionutrics Distillate Products, Rice Bran Oil Distillate,
Derivative Products and Rice Bran Products to Bionutrics at no cost to

         B.      In the event there is any actual or threatened recall or

litigation, claim, or governmental proceeding involving the quality or safety
of any the Bionutrics Distillate Products, Rice Bran Oil Distillate, Derivative
Products and Rice Bran Products, the parties will cooperate in good faith with
one another to address such matters.

9.       RISK OF LOSS.  Humko assumes all risk of loss or damage to all the
Bionutrics Distillate Products, Rice Bran Oil Distillate, Derivative Products
and Rice Bran Products prior to delivery to Bionutrics in accordance with
orders placed by Bionutrics pursuant to Sections 3.D and 3.E and other
applicable terms of this Agreement.

10.      FORCE MAJEURE, HUMKO'S OPTION AND DEFAULT.

         A.      Notwithstanding anything to the contrary contained in this
Agreement, delays by Humko in the performance or non-performance of its
obligations under this Agreement will be excused if due to any cause beyond
Humko's reasonable control, including, by way of example only and not
limitation, acts of God, governmental laws, rules, or regulations, wars, fires,
the elements, labor troubles , interruption or shortage of transport
facilities, or inability to obtain raw material or packaging supplies.

         B.      At any time and from time to time, Humko may, at its sole
option, upon nine (9) months written notice to Bionutrics and for reasons other
than as set forth in Section 10.A: (i) choose not to supply the requirements,
or any portion thereof, of Bionutrics Distillate Products or Rice Bran Products
as required by this Agreement to Bionutrics under this Agreement for any





                                      E-13
<PAGE>   86



period of time or (ii) choose not to supply its output, or any portion thereof,
of the Rice Bran Oil Distillate (subject to the terms of Sections 3.A(iii) and
(iv)) or Derivative Products, or any portions of such requirements or output,
to Bionutrics under this Agreement for any period of time.  The exercise of
such option by Humko shall, at Bionutrics sole option, excuse Bionutrics'
obligation to purchase the supply or requirements, as the case may be, of the
applicable Bionutrics Distillate Products or the Rice Bran Products or the
output, as the case may be, of the Rice Bran Oil Distillate or Derivative
Products to the extent the exercise of such option by Humko impacts the supply
or requirements.  To the extent that Humko has exercised its option to no
longer supply Bionutrics' requirements of Bionutrics Distillate Products, Humko
grants to Bionutrics a limited, nonexclusive, nontransferable license to use
the Intellectual Property to import Bionutrics Distillate from outside North
America to produce Bionutrics Distillate Products in its own facilities (and
the facilities of its subsidiaries and Affiliates).  To the extent that Humko
has exercised its option to no longer supply Bionutrics with its requirements
of any Rice Bran Product, Bionutrics shall be free to contract with third
parties for its additional requirements of such Rice Bran Product.  This
Agreement shall not be construed to grant to Bionutrics, and Humko expressly
negates and reserves, any rights to use any of the Intellectual Property with
respect to the production of Rice Bran Oil Distillate in North America.
Similarly, this Agreement shall not be construed to grant to Bionutrics or any
third party supplying Bionutrics with such Rice Bran Product, and Humko
expressly negates and reserves, any rights to use any of the Intellectual
Property with respect to the processing of such Rice Bran Products or such
Bionutrics Products in North America to Bionutrics.  Bionutrics expressly
covenants not to use in North America the Intellectual Property with respect to
the production of any Rice Bran Products or such Bionutrics Products.

         C.      If either party defaults in the performance of its obligations
under this Agreement, the non-defaulting party immediately will notify the
defaulting party of such default and the time to cure such default, which time
will be five days in the case of a failure to pay amounts due for the
Bionutrics Distillate Products, Rice Bran Oil Distillate, Derivative Products
and Rice Bran Products (but only given twice per calendar year), and 30 days
for all other defaults, after the defaulting party receives such notice of the
default; provided, however, if such non-monetary default is curable but
requires work to be performed, acts to be done or conditions to be remedied
which, by their nature, cannot be performed, done or remedied, as the case may
be, within such 30-day period, then no default shall be deemed to have occurred
if the defaulting party commences same within such 30-day period and thereafter
diligently and continuously prosecutes the same until completion.  Subject to
the foregoing provisions of this Section 10.C., any default by either party
under this Agreement shall entitle the other party to all remedies available at
law or in equity including, without limitation, the right to terminate this
Agreement upon notice to the defaulting party.  The termination of this
Agreement in whole or in part pursuant to this Section 10.C.  will not relieve
either party from the obligations in this Agreement which survive termination.
Each of the following shall also constitute a default under this Agreement:





                                      E-14
<PAGE>   87



         (1)     the entry of an "Order for Relief" naming a party as a
         "Debtor" under Title 11 of the United States Code or upon the entry of
         a decree or order by a court having competent jurisdiction in respect
         to any petition filed or action respecting a party directly involved
         in a reorganization, arrangement, creditors' composition,
         readjustment, liquidation, dissolution, bankruptcy, or similar relief
         under any other present or future United States or other statute, law
         or regulation, whether or not resulting in the appointment of a
         receiver, liquidator, assignee, trustee, custodian, sequestrator or
         other similar official, and any such decree or order is in effect for
         a period of thirty (30) consecutive days;

         (2)     the making by a party of an assignment for the benefit of
         creditors, or the admission by such party in writing of its inability
         to pay its debts generally as they become due, or the taking of action
         by a party in furtherance of any such action; or

         (3)     as expressly provided elsewhere in this Agreement.

         D.      During any force majeure event under Section 10.A., or default
by Humko, Bionutrics, as its sole and exclusive remedy, may remove any or all
of the impacted part of the Bionutrics Distillate Products, Rice Bran Oil
Distillate, Derivative Products and Rice Bran Products business from Humko and
obtain such Bionutrics Distillate Products, Rice Bran Oil Distillate,
Derivative Products and Rice Bran Products from any other supplier during the
applicable period of such force majeure event or the period of such default;
provided, however, when the period covered by such force majeure events or
Humko's exercise of the option contained in Section 10.B., or when such default
is cured by Humko, Bionutrics shall, upon ninety (90) days written notice,
cease purchasing the Bionutrics Distillate Products, Rice Bran Oil Distillate,
Derivative Products and Rice Bran Products or any products similar thereto from
other suppliers and shall continue purchasing the Bionutrics Distillate
Products, Rice Bran Oil Distillate, Derivative Products and Rice Bran Products
solely from Humko under this Agreement. This Agreement shall not be construed
to grant to Bionutrics, and Humko expressly negates and reserves, any rights to
use any of the Intellectual Property with respect to the production of
Bionutrics Distillate, Rice Bran Oil Distillate and Rice Bran Products in North
America.  Similarly, this Agreement shall not be construed to grant to
Bionutrics or any third party supplying Bionutrics with such Bionutrics
Distillate Products, Rice Bran Oil Distillate or Rice Bran Products, and Humko
expressly negates and reserves, any rights to use any of the Intellectual
Property with respect to the processing of, such Bionutrics Distillate
Products, Rice Bran Oil Distillate or Rice Bran Products or such Bionutrics
Products in North America to Bionutrics.

         E.      No failure by any party to exercise any right given in this
Agreement or to insist on strict compliance by the other party of any
obligation under this Agreement will constitute a waiver of the party's right
to later demand exact compliance with the terms of this Agreement.

11.      INDEMNIFICATION.  Bionutrics will defend, indemnify, and hold harmless
Humko and its parents, subsidiaries, Affiliates, successors, and assigns, and
their respective officers, directors, employees, agents, and contractors from
and against (i) any and all claims, demands, liabilities, losses, damages,
cost, or expenses (including reasonable attorneys' fees), including by way of
example only and not limitation for death, personal injury, property damage, or
otherwise to the extent based on, arising out of, or in any way related to
Bionutrics' or its parents', subsidiaries', Affiliates', successors', or
assigns', or their respective officers', directors', employees', agents', or
contractors' failure to perform its obligations under this Agreement, or any
negligent act, misfeasance, malfeasance, non-feasance or strict liability by
Bionutrics or its parents, subsidiaries, Affiliates, successors, or assigns, or
their respective officers, directors, employees, agents, or contractors, and
(ii) any and all fees (including reasonable attorney's fees), costs, and
expenses incurred by Humko or its parents, subsidiaries, Affiliates,
successors, or assigns, or their respective officers, directors, employees,
agents, or contractors in the investigation, correction, or defense against any
and all such losses, claims, or threatened claims; except to the extent any
such claim for loss, cost, expense, damage, or liability is the direct result
of the acts or negligence of Humko or its parents, subsidiaries, Affiliates,
successors, or assigns, or their respective officers, directors, employees,
agents, or contractors.  If Humko receives notice of any claim for which it
considers Bionutrics responsible under this Section 11, Humko promptly will
inform Bionutrics in writing.

12.      NOTICES.  Any notice or other communication required or permitted in

13.      CONFIDENTIALITY.

         A.      Except for the proper exercise of any rights granted or
reserved under other provisions of this Agreement, and except for any other
confidentiality provisions set forth in any other agreement or instrument
involving Bionutrics (or any of its Affiliates or subsidiaries) and Humko,
Bionutrics (and its Affiliates and subsidiaries) will take such precautions as
it normally takes with its own confidential or proprietary information to keep
confidential and not to publish or otherwise disclose to a third party without
the prior written consent of Humko, except as permitted or anticipated in this
Agreement, any information of a proprietary nature furnished by Humko in
connection with this Agreement, including by way of example only and not
limitation technology, marketing strategy, specifications, product information,
data, inventions, processes, know-how, sales force information, sales data,
plans, trade secrets, call lists, customer lists, business information, adverse
reaction reports, and this Agreement (collectively called "Confidential
Information") without the prior written consent of Humko except, subject to
Section

<PAGE>   90



13.C below, to the extent that such Confidential Information is required to be
disclosed for purposes of complying with governmental laws and regulations.

         B.      Bionutrics will disclose Confidential Information of Humko
only to those of its employees that have a need for access to it in order to
enable Bionutrics to perform under this Agreement; provided, however, that
Bionutrics has first advised all persons who receive any of the Confidential
Information of its confidential nature, and provided, further, that Bionutrics
has first obtained assurances from all such persons that they will abide by the
terms and conditions of this Confidentiality Agreement as if such persons were
parties hereto.

         C.      Nothing in this Section 13 will prevent disclosure or use of
Confidential Information that is required to be disclosed by applicable law or
regulation or by order of a court or regulatory body having competent
jurisdiction, and (a) Bionutrics, in writing and in advance of any disclosure,
makes the requesting entity aware of Bionutrics' obligations of confidentiality
in this Agreement, and (b) Bionutrics provides timely written notice to Humko
in advance of any disclosure to the court, regulatory body, or other entity so
as to permit Humko to address with the requesting party any concerns of Humko
regarding such requested disclosure.

         D.      After the effective date of the termination or expiration of
this Agreement, and within 30 days following receipt of a written request from
Humko, Bionutrics will return to Humko its tangible Confidential Information.

         E.      The provisions of this Section 13 will apply during the Term
of this Agreement and for five years following the Term.

14.      SALE, TRANSFER, ASSIGNMENT, AND CHANGES IN MANAGEMENT.

         A.      This Agreement will bind and inure to the benefit of the
