sent as set forth in the Purchase Agreement.

            2.3. This Escrow Agreement shall be binding upon and shall inure to
the benefit of the permitted successors and permitted assigns of the parties
hereto.

            2.4. This Escrow Agreement is the final expression of, and contains
the entire agreement between, the parties with respect to the subject matter
hereof and supersedes all prior understandings with respect thereto. This Escrow
Agreement may not be modified, changed, supplemented or terminated, nor may any
obligations hereunder be waived, except by written instrument signed by the
parties to be charged or by their respective agents duly authorized in writing
or as otherwise expressly permitted herein.

            2.5. Whenever required by the context of this Escrow Agreement, the
singular shall include the plural and masculine shall include the feminine. This
Escrow Agreement shall not be construed as if it had been prepared by one of the
parties, but rather as if both parties had prepared the same. Unless otherwise
indicated, all references to Articles are to this Escrow Agreement.

            2.6. The parties hereto expressly agree that this Escrow Agreement
shall be governed by, interpreted under and construed and enforced in accordance
with the laws of the State of New York. Any action to enforce, arising out of,
or relating in any way to, any provisions of this Escrow Agreement shall only be
brought in a state or Federal court sitting in New York City.

            2.7. The Escrow Agent's duties hereunder may be altered, amended,
modified or revoked only by a writing signed by the Company, each Investor and
the Escrow Agent.

            2.8. The Escrow Agent shall be obligated only for the performance of
such duties as are specifically set forth herein and may rely and shall be
protected in relying or refraining from acting on any instrument reasonably
believed by the Escrow Agent to be genuine and to have been signed or presented
by the proper party or parties. The Escrow Agent shall not be personally liable
for any act the Escrow Agent may do or omit to do hereunder as the Escrow Agent
while acting in good faith, and without gross negligence or willful misconduct.

            2.9. The Escrow Agent is hereby expressly authorized to disregard
any and all warnings given by any of the parties hereto or by any other person
or corporation, excepting only orders or process of courts of law and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Escrow Agent obeys or complies with any such order, judgment
or decree, the Escrow Agent shall not be liable to any of the parties hereto or
to any other person, firm or corporation by reason of such decree being
subsequently reversed, modified, annulled, set aside, vacated or found to have
been entered without jurisdiction.

            2.10. The Escrow Agent shall not be liable in any respect on account
of the identity, authorization or rights of the parties executing or delivering
or purporting to execute or deliver the Purchase Agreement or any documents or

            2.11. The Escrow Agent shall be entitled to employ such legal
counsel and other experts as the Escrow Agent may deem necessary properly to
advise the Escrow Agent in connection with the Escrow Agent's duties hereunder,
may rely upon the advice of such counsel, and may pay such counsel reasonable
compensation therefor. THE ESCROW AGENT HAS ACTED AS LEGAL COUNSEL FOR THE
INVESTORS, AND MAY CONTINUE TO ACT AS LEGAL COUNSEL FOR THE INVESTORS, FROM TIME
TO TIME, NOTWITHSTANDING ITS DUTIES AS THE ESCROW AGENT HEREUNDER. THE COMPANY
CONSENTS TO THE ESCROW AGENT IN SUCH CAPACITY AS LEGAL COUNSEL FOR THE INVESTORS
AND WAIVES ANY CLAIM THAT SUCH REPRESENTATION REPRESENTS A CONFLICT OF INTEREST
ON THE PART OF THE ESCROW AGENT. THE COMPANY UNDERSTANDS THAT THE INVESTORS AND
THE ESCROW AGENT ARE RELYING EXPLICITLY ON THE FOREGOING PROVISION IN ENTERING
INTO THIS ESCROW AGREEMENT.

            2.12. The Escrow Agent's responsibilities as escrow agent hereunder
shall terminate if the Escrow Agent shall resign by written notice to the
Company and the Investors. In the event of any such resignation, the Investors
and the Company shall appoint a successor Escrow Agent.

            2.13. If the Escrow Agent reasonably requires other or further
instruments in connection with this Escrow Agreement or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

            2.14. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the documents
or the escrow funds held by the Escrow Agent hereunder, the Escrow Agent is
authorized and directed in the Escrow Agent's sole discretion (1) to retain in
the Escrow Agent's possession without liability to anyone all or any part of
said documents or the escrow funds until such disputes shall have been settled
either by mutual written agreement of the parties concerned by a final order,
decree or judgment of a court of competent jurisdiction after the time for
appeal has expired and no appeal has been perfected, but the Escrow Agent shall
be under no duty whatsoever to institute or defend any such proceedings or (2)
to deliver the escrow funds and any other property and documents held by the
Escrow Agent hereunder to a state or Federal court having competent subject
matter jurisdiction and located in the City of New York in accordance with the
applicable procedure therefor.

            2.15. The Company and each Investor agree jointly and severally to
indemnify and hold harmless the Escrow Agent and its partners, employees, agents
and representatives from any and all claims, liabilities, costs or expenses in
any way arising from or relating to the duties or performance of the Escrow
Agent hereunder or the transactions contemplated hereby or by the Purchase
Agreement other than any such claim, liability, cost or expense to the extent
the same shall have been determined by final, unappealable judgment of a court
of competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the Escrow Agent.

                                                                       EXHIBIT C

NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON EXERCISE HEREOF HAVE BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT")
OR ANY OTHER APPLICABLE SECURITIES LAWS IN RELIANCE UPON AN EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT PURSUANT TO REGULATION D AND
SUCH OTHER SECURITIES LAWS. NEITHER THIS WARRANT NOR THE SHARES ISSUABLE UPON
EXERCISE HEREOF MAY BE SOLD, PLEDGED, TRANSFERRED, ENCUMBERED OR OTHERWISE
DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT OR IN A TRANSACTION WHICH IS EXEMPT FROM REGISTRATION UNDER THE
PROVISIONS OF THE SECURITIES ACT OR ANY APPLICABLE STATE LAWS.

                             STOCK PURCHASE WARRANT

                  To Purchase 50,000 Shares of Common Stock of

                                BIONUTRICS, INC.

                  THIS CERTIFIES that, for value received, AMRO International,
S.A. (the "Holder"), is entitled, upon the terms and subject to the conditions
hereinafter set forth, at any time on or after September 22, 2000 (the "Initial
Exercise Date") and on or prior to the close of business on September 22, 2003
(the "Termination Date") but not thereafter, to subscribe for and purchase from
Bionutrics, Inc., a Nevada corporation (the "Company"), up to 50,000 shares (the
"Warrant Shares") of Common Stock, $.001 par value, of the Company (the "Common
Stock"). The purchase price of one share of Common Stock (the "Exercise Price")
under this Warrant shall be $1.1001 (the VWAP of the Common Stock on the Trading
Day immediately prior to the Closing Date). The Exercise Price and the number of
shares for which the Warrant is exercisable shall be subject to adjustment as
provided herein. In the event of any conflict between the terms of this Warrant
and the Common Stock and Warrants Purchase Agreement dated September 20, 2000
pursuant to which this Warrant has been issued (the "Purchase Agreement"), the
Purchase Agreement shall control. Capitalized terms used and not otherwise
defined herein shall have the meanings set forth for such terms in the Purchase
Agreement.

                                       1
<PAGE>   2
         1. Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

         2. Authorization of Shares. The Company covenants that all shares of
Common Stock which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

         3. Exercise of Warrant. Except as provided in Section 4 herein,
exercise of the purchase rights represented by this Warrant may be made at any
time or times on or after the Initial Exercise Date and before the close of
business on the Termination Date. Exercise of this Warrant or any part hereof
shall be effected by the surrender of this Warrant and the Notice of Exercise
Form annexed hereto duly executed, at the office of the Company (or such other
office or agency of the Company as it may designate by notice in writing to the
registered holder hereof at the address of such holder appearing on the books of
the Company) and upon payment of the Exercise Price of the shares thereby
purchased by wire transfer or cashier's check drawn on a United States bank, the
holder of this Warrant shall be entitled to receive a certificate for the number
of shares of Common Stock so purchased. Certificates for shares purchased
hereunder shall be delivered to the holder hereof within three (3) Trading Days
after the date on which this Warrant shall have been exercised as aforesaid.
This Warrant shall be deemed to have been exercised and such certificate or
certificates shall be deemed to have been issued, and Holder or any other person
so designated to be named therein shall be deemed to have become a holder of
record of such shares for all purposes, as of the date the Warrant has been
exercised by payment to the Company of the Exercise Price and all taxes required
to be paid by Holder, if any, pursuant to Section 5 prior to the issuance of
such shares, have been paid. If this Warrant shall have been exercised in part,
the Company shall, at the time of delivery of the certificate or certificates
representing Warrant Shares, deliver to Holder a new Warrant evidencing the
rights of Holder to purchase the unpurchased shares of Common Stock called for
by this Warrant, which new Warrant shall in all other respects be identical with
this Warrant.

This Warrant may also be exercised by means of a "cashless exercise" in which
the holder shall be entitled to receive a certificate for the number of shares
equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

         (A) = the average of the high and low trading prices per share of
Common Stock on the Trading Day preceding the date of such election;

         (B) = the Exercise Price of the Warrants; and

         (X) = the number of shares issuable upon exercise of the Warrants in
accordance with the terms of this Warrant.

                                       2
<PAGE>   3
         4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

         5. Charges, Taxes and Expenses. Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant shall be made without charge to
the holder hereof for any issue or transfer tax or other incidental expense in
respect of the issuance of such certificate, all of which taxes and expenses
shall be paid by the Company, and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant; provided, however, that in the event certificates for
shares of Common Stock are to be issued in a name other than the name of the
holder of this Warrant, this Warrant when surrendered for exercise shall be
accompanied by the Assignment Form attached hereto duly executed by the holder
hereof; and the Company may require, as a condition thereto, the payment of a
sum sufficient to reimburse it for any transfer tax incidental thereto.

         6. Closing of Books. The Company will not close its shareholder books
or records in any manner which prevents the timely exercise of this Warrant.

         7. Transfer, Division and Combination. (a) Subject to compliance with
any applicable securities laws, transfer of this Warrant and all rights
hereunder, in whole or in part, shall be registered on the books of the Company
to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by Holder or its
agent or attorney and funds sufficient to pay any transfer taxes payable upon
the making of such transfer. In the event the Holder wishes to transfer this
Warrant, the Holder shall transfer rights to purchase at least 10,000 shares to
such transferee. Upon such surrender and, if required, such payment, the Company
shall execute and deliver a new Warrant or Warrants in the name of the assignee
or assignees and in the denomination or denominations specified in such
instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled. A Warrant, if properly assigned, may be exercised by a
new holder for the purchase of shares of Common Stock without having a new
Warrant issued.

                  (b) This Warrant may be divided or combined with other
Warrants upon presentation hereof at the aforesaid office of the Company,
together with a written notice specifying the names and denominations in which
new Warrants are to be issued, signed by Holder or its agent or attorney.
Subject to compliance with Section 7(a), as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver
a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided
or combined in accordance with such notice.

                                       3
<PAGE>   4
                  (c) The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 7.

                  (d) The Company agrees to maintain, at its aforesaid office,
books for the registration and the registration of transfer of the Warrants.

         8. No Rights as Shareholder until Exercise. This Warrant does not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company prior to the exercise hereof. Upon the surrender of this Warrant
and the payment of the aggregate Exercise Price, the Warrant Shares so purchased
shall be and be deemed to be issued to such holder as the record owner of such
shares as of the close of business on the later of the date of such surrender or
payment.

         9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant certificate
or any stock certificate relating to the Warrant Shares, and in case of loss,
theft or destruction, of indemnity or security reasonably satisfactory to it
(which shall not include the posting of any bond), and upon surrender and
cancellation of such Warrant or stock certificate, if mutilated, the Company
will make and deliver a new Warrant or stock certificate of like tenor and dated
as of such cancellation, in lieu of such Warrant or stock certificate.

         10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

         11. Adjustments of Exercise Price and Number of Warrant Shares.

                  (a) Stock Splits, etc. The number and kind of securities
purchasable upon the exercise of this Warrant and the Exercise Price shall be
subject to adjustment from time to time upon the happening of any of the
following. In case the Company shall (i) pay a dividend in shares of Common
Stock or make a distribution in shares of Common Stock to holders of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock
into a greater number of shares of Common Stock, (iii) combine its outstanding
shares of Common Stock into a smaller number of shares of Common Stock or (iv)
issue any shares of its capital stock in a reclassification of the Common Stock,
then the number of Warrant Shares purchasable upon exercise of this Warrant
immediately prior thereto shall be adjusted so that the holder of this Warrant
shall be entitled to receive the kind and number of Warrant Shares or other
securities of the Company which he would have owned or have been entitled to
receive had such Warrant been exercised in advance thereof. Upon each such
adjustment of the kind and number of Warrant Shares or other securities of the
Company which are purchasable hereunder, the holder of this Warrant shall
thereafter be entitled to purchase the number of Warrant Shares or other
securities resulting from such adjustment at an Exercise Price per Warrant Share
or other security obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of Warrant Shares purchasable
pursuant hereto immediately prior to such adjustment and dividing by the number
of Warrant Shares or other securities of the Company resulting from such

                                       4
<PAGE>   5
adjustment. An adjustment made pursuant to this paragraph shall become effective
immediately after the effective date of such event retroactive to the record
date, if any, for such event.

                  (b) Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then Holder shall have the right thereafter to receive, upon
exercise of this Warrant, the number of shares of common stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation,
and Other Property receivable upon or as a result of such reorganization,
reclassification, merger, consolidation or disposition of assets by a holder of
the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such event. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Company) shall expressly assume the
due and punctual observance and performance of each and every covenant and
condition of this Warrant to be performed and observed by the Company and all
the obligations and liabilities hereunder, subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of shares of
Common Stock for which this Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 11.
For purposes of this Section 11, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or assets over any other class of stock of such
corporation and which is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities which are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event and any
warrants or other rights to subscribe for or purchase any such stock. The
foregoing provisions of this Section 11 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

         12. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

         13. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the holder of this Warrant notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Warrant Shares (and other securities or property) after such adjustment, setting
forth a brief statement of the facts

                                       5
<PAGE>   6
requiring such adjustment and setting forth the computation by which such
adjustment was made. Such notice, in the absence of manifest error, shall be
conclusive evidence of the correctness of such adjustment.

         14. Notice of Corporate Action. If at any time:

                  (a) the Company shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

                  (b) there shall be any capital reorganization of the Company,
any reclassification or recapitalization of the capital stock of the Company or
any consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation or,

                  (c) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 20 calendar days' prior written notice of the date on which a record date
shall be selected for such dividend, distribution or right or for determining
rights to vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 20
calendar days' prior written notice of the date when the same shall take place.
Such notice in accordance with the foregoing clause also shall specify (i) the
date on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of the Company and
delivered in accordance with Section 16(d). To the extent that the notice
required to be given to Holder hereunder is material, non-public information,
then such Holder shall sign such confidentiality agreement with the Company as
it or its counsel may reasonably require to protect against the premature
disclosure of such event.

         15. Authorized Shares. The Company covenants that during the period the
Warrant is outstanding, it will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of the Warrant
Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full
authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such

                                       6
<PAGE>   7
reasonable action as may be necessary to assure that such Warrant Shares may be
issued as provided herein without violation of any applicable law or regulation,
or of any requirements of the Principal Market upon which the Common Stock may
be listed.

                  The Company shall not by any action, including, without
limitation, amending its articles of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant, and (c) use all commercially
reasonable efforts to obtain all such authorizations, exemptions or consents
from any public regulatory body having jurisdiction thereof as may be necessary
to enable the Company to perform its obligations under this Warrant.

                  Upon the request of Holder, the Company will at any time
during the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant and
the obligations of the Company hereunder.

                  Before taking any action which would cause an adjustment
reducing the current Exercise Price below the then par value, if any, of the
shares of Common Stock issuable upon exercise of the Warrants, the Company shall
take any corporate action which may be necessary in order that the Company may
validly and legally issue fully paid and non-assessable shares of such Common
Stock at such adjusted Exercise Price.

                  Before taking any action which would result in an adjustment
in the number of shares of Common Stock for which this Warrant is exercisable or
in the Exercise Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

         16. Miscellaneous.

                  (a) Jurisdiction. This Warrant shall be binding upon any
successors or assigns of the Company. This Warrant shall constitute a contract
under the laws of New York without regard to its conflict of law principles or
rules, and be subject to arbitration pursuant to the terms set forth in the
Purchase Agreement.

                  (b) Restrictions. The holder hereof acknowledges that the
Warrant Shares acquired upon the exercise of this Warrant, if not registered,
will have restrictions upon resale imposed by state and federal securities laws.

                                       7
<PAGE>   8
                  (c) Nonwaiver and Expenses. No course of dealing or any delay
or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice Holder's rights, powers or
remedies, notwithstanding all rights hereunder terminate on the Termination
Date. If the Company willfully fails to comply with any material provision of
this Warrant, the Company shall pay to Holder such amounts as shall be
sufficient to cover any costs and expenses including, but not limited to,
reasonable attorneys' fees, including those of appellate proceedings, incurred
by Holder in collecting any amounts due pursuant hereto or in otherwise
enforcing any of its rights, powers or remedies hereunder.

                  (d) Notices. Any notice, request or other document required or
permitted to be given or delivered to the holder hereof by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement.

                  (e) Limitation of Liability. No provision hereof, in the
absence of affirmative action by Holder to purchase shares of Common Stock, and
no enumeration herein of the rights or privileges of Holder hereof, shall give
rise to any liability of Holder for the purchase price of any Common Stock or as
a stockholder of the Company, whether such liability is asserted by the Company
or by creditors of the Company.

                  (f) Remedies. Holder, in addition to being entitled to
exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant. The Company
agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of the provisions of this Warrant and
hereby agrees to waive the defense in any action for specific performance that a
remedy at law would be adequate.

                  (g) Successors and Assigns. Subject to applicable securities
laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors of the Company and the
successors and permitted assigns of Holder. The provisions of this Warrant are
intended to be for the benefit of all Holders from time to time of this Warrant
and shall be enforceable by any such Holder or holder of Warrant Shares.

                  (h) Indemnification. The Company agrees to indemnify and hold
harmless Holder from and against any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, attorneys' fees, expenses
and disbursements of any kind which may be imposed upon, incurred by or asserted
against Holder in any manner relating to or arising out of any failure by the
Company to perform or observe in any material respect any of its covenants,
agreements, undertakings or obligations set forth in this Warrant; provided,
however, that the Company will not be liable hereunder to the extent that any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs, attorneys' fees, expenses or disbursements are found in a final
non-appealable judgment by a court to have resulted from Holder's negligence,
bad faith or willful misconduct in its capacity as a stockholder or
warrantholder of the Company.

                  (i) Amendment. This Warrant may be modified or amended or the
provisions hereof waived with the written consent of the Company and the Holder.

                                       8
<PAGE>   9
                  (j) Severability. Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

                  (k) Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.
