                            STOCK PURCHASE AGREEMENT


                   THIS STOCK PURCHASE AGREEMENT (the "Agreement") is made as of
the 25th day of October, 2000, by and between Bionutrics, Inc., a Nevada
corporation (the "Company"), and Tamarack International Limited (the
"Investor").

THE PARTIES HEREBY AGREE AS FOLLOWS:

         1.        Purchase and Sale of Stock.

                   1.1 Sale and Issuance of Stock. On the basis of the
representations, warranties and agreements contained herein and subject to the
terms and conditions herein set forth, the Company agrees to issue and sell
500,000 (five hundred thousand) shares of its Common Stock, $.001 par value, at
$1.00 per share (the "Shares"), and the Investor hereby subscribes for and
agrees to purchase the Shares upon acceptance of this Agreement by the Company.

                   1.2 Payment. Investor is delivering with this Agreement the
full amount of the purchase price of the Shares in the amount of $500,000 in
U.S. funds by wire transfer as directed by the Company to the Company's
designated escrow account. Such funds deposited into the escrow account on
behalf of the Investor shall be held until the conditions for the Closing of the
offering have been met.

                   1.3 Closing. The closing of the transaction contemplated by
this Agreement (the "Closing") shall be deemed to have occurred when this
Agreement has been executed by both the Investor and the Company and payment
shall have been made as set forth in 1.2 above in consideration for the
Company's delivery into the escrow account of certificates representing the
Shares subscribed for. If at the Closing any of the conditions specified in
Section 6 hereof shall not have been fulfilled to the reasonable satisfaction of
Investor, then Investor shall, at its election, be relieved of all of its
obligations under this Agreement, without thereby waiving any other rights it
may have by reason of such failure or unfulfillment. If at the Closing any of
the conditions specified in Section 5 hereof shall not have been fulfilled to
the reasonable satisfaction of the Company, the Company shall, at its election,
be relieved of all of its
<PAGE>   2
obligations under this Agreement, without thereby waiving any other rights it
may have by reason of such failure or unfulfillment.

         2.        Representation and Warranties of the Company.  The Company
hereby represents and warrants to the Investor as follows:

                   2.1 Organization, Good Standing and Qualification. The
Company is a corporation validly existing and in good standing under the laws of
the State of Nevada and has all requisite power and authority to own or lease
and operate its properties and assets and to carry on its business as now
conducted. The Company is duly qualified to transact business and is in good
standing in each jurisdiction in which the failure to so qualify would have a
material adverse effect on its business, operations, prospects, condition
(financial or other), or properties.

                  2.2 Capitalization. The authorized capital of the Company
consists of:

                           (i) Common Stock. 45,000,000 shares of common stock
("Common Stock"), par value $.001, of which 20,936,252 shares are issued and
outstanding as of August 31, 2000.

                           (ii) Preferred Stock. 5,000,000 shares of preferred
stock ("Preferred Stock"), par value $.001, none of which is outstanding. The
Preferred Stock may be issued from time to time in one or more series and the
Board of Directors is authorized to fix the rights and terms relating to
dividends, conversion, voting, redemption, liquidation preferences and any other
rights, preferences, privileges and restrictions applicable to each such series.

                           (iii) Warrants, Options and Other Rights. There are
no preemptive rights or rights of first refusal for the purchase or acquisition
from the Company of any shares of its capital stock. As of August 31, 2000,
there were outstanding warrants to purchase up to 1,180,000 shares of Common
Stock. As of August 31, 2000, options in the amount of 2,121,144 shares were
outstanding and held by current or former employees, officers and directors
pursuant to the Company's Stock Option Plan and 386,667 were outstanding and
held by others.

                   2.3 Valid Issuance of Shares. All of the outstanding shares
of the Company's stock have been duly and validly authorized and issued, are
fully paid and nonassessable, and no further approval or authority of the
stockholders or the directors of the Company will be required by the Company for
the issuance of the Shares. The Shares when issued and paid for in accordance
with the terms of this Agreement will be duly and validly issued, fully paid and
nonassessable and will be free of restrictions on transfer other than
restrictions on transfer under applicable state and federal securities laws.

                   2.4 Financial Statements. Except as otherwise stated in the
notes thereto, the audited financial statements contained in the Form 10-K for
the year ended October 31, 1999 and the unaudited financial statements contained
in the Forms 10-Q filed subsequent thereto have been prepared in conformity with
United States generally accepted accounting principles applied, except as stated
therein, on a consistent basis. The financial statements fairly present the
financial position and result of operations and changes in financial position of
the Company as of the dates and for the periods indicated.

         Except as reflected in such financial statements and the notes thereto,
the Company has no liabilities, absolute or contingent, material to the
operations, business, prospects, assets, properties or


                                       2
<PAGE>   3
condition (financial or other) of the Company, other than (i) ordinary course
liabilities incurred since the last date of such financial statements in
connection with the conduct of the business of the Company, and (ii) obligations
under contracts and commitments incurred in the ordinary course of business and
not required under United States generally accepted accounting principles to be
reflected in the financial statements, which, in both cases, individually or in
the aggregate, are not material to the financial condition or operating results
of the Company.

                   2.5 No Conflict with Other Instruments. Neither the sale of
the Shares nor the consummation of the transactions herein contemplated, will:
(i) conflict with or constitute a breach of, permit the termination of,
constitute a default under, or violation of (A) the Articles of Incorporation,
as amended, or bylaws of the Company, (B) any material agreement, indenture,
mortgage, deed of trust or other material instrument or agreement or undertaking
by which the Company is bound or to which any of its properties is subject, or,
(C) to the knowledge of the Company, a violation of any law, administrative
regulation, or court decree to which the properties or assets of the Company is
subject; or (ii) result in the creation or imposition of any material lien,
charge or encumbrance upon the property or assets of the Company.

                   2.6 Authorization. The Company has the corporate power and
authority to enter into this Agreement and to perform all of its obligations
hereunder. The execution, delivery and performance of this Agreement by the
Company have been duly authorized by all necessary corporate actions, and this
Agreement constitutes a legal, valid, binding and enforceable obligation of the
Company. No consent, approval, authorization or order of any court or
governmental agency or board or any other third party, or registration,
qualification, designation or filing with any Federal, state or local authority
is required to consummate the transactions contemplated by this Agreement.

         3.        Representations and Warranties of Investor.  By executing
this Agreement, Investor hereby represents and warrants to and covenants with
the Company as follows:

                   3.1 Authorization. Investor has the power and authority to
enter into this Agreement and to perform all of its obligations hereunder and
this Agreement constitutes a valid, binding and enforceable obligation of

                   3.2 Legal Investment and Compliance with Laws. The purchase
of the Shares by Investor is legally permitted by all laws and regulations to
which Investor is subject and all consents, approvals, authorizations of or
designations, declarations, or filings in connection with the valid execution
and delivery of this Agreement by Investor or the purchase of the Shares by
Investor has been obtained, or will be obtained. Investor hereby represents that
it has satisfied itself as to the full observance of the laws of its
jurisdiction in connection with any invitation to subscribe for the Shares or
any use of this Agreement, including (i) any foreign exchange restrictions
applicable to such purchase, and (ii) the income tax and other tax consequences,
if any, which may be relevant to the purchase, holding, redemption, sale, or
transfer of the Shares. Such Investor's subscription and payment for, and its
continued beneficial ownership of the Shares, will not violate any applicable

the investment and to verify the accuracy of the information supplied.

                           (d) Investor represents and warrants that, in
determining to purchase the Shares, it has relied solely upon the documents
provided and the advice of its advisors with respect to the tax, foreign and
U.S., and other consequences involved in purchasing the Shares.
