is in good standing as a foreign corporation in every jurisdiction in which the

corporate power and authority to enter into and perform its obligations under
this Agreement, the Registration Rights Agreement, the Escrow Agreement and the

Company or its Board of Directors or stockholders is required, and (iii) this
Agreement, the Registration Rights Agreement, the Escrow Agreement, the Common
Stock certificates representing the Shares and the Warrants have been duly
executed and delivered by the Company and at each Closing shall constitute valid
and binding obligations of the Company enforceable against the Company in
accordance with their terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation,
conservatorship, receivership or similar laws relating to, or affecting
generally the enforcement of, creditors' rights and remedies or by other
equitable principles of general application. The Company has duly and validly
authorized and reserved for issuance shares of Common Stock sufficient in number
for the issuance of the Warrant Shares.

consists of 45,000,000 shares of Common Stock, of which 20,936,252 shares are

contracts, commitments, understandings, or arrangements by which the Company is
or may become bound to issue additional shares of the capital stock of the
Company or options, securities or rights convertible into shares of capital
stock of the Company. Except as set forth in Schedule 4.1(c), the Company is not
a party to any agreement granting registration rights to any person with respect
to any of its equity or debt securities. Except as set forth in Schedule 4.1(c),
the Company is not a party to, and it has no knowledge of, any agreement

Company. Except as set forth in the SEC Documents or on Schedule 4.1(c) hereto,
the offer and sale of all capital stock, convertible securities, rights,
warrants, or options of the Company issued prior to the Closing complied with
all applicable federal and state securities laws, and no stockholder has a right
of rescission or damages with respect thereto which would have a Material
Adverse Effect on the Company's financial condition or operating results. The

state, local or other foreign statute, rule, regulation, order, judgment or
decree (including any federal or state securities laws and regulations)
applicable to the Company or any of its subsidiaries or by which any property or
asset of the Company or any of its subsidiaries are bound or affected, except,
in all cases, for such conflicts, defaults, termination, amendments,
accelerations, cancellations and violations as would not, individually or in the
aggregate, have a Material Adverse Effect. The business of the

                                       8
<PAGE>   9
Company and its subsidiaries is not being conducted in violation of any laws,

Material Adverse Effect. The Company is not required under any federal, state or
local law, rule or regulation to obtain any consent, authorization or order of,
or make any filing or registration with, any court or governmental agency in

documents required to be filed by it with the SEC pursuant to the reporting
requirements of the Exchange Act, including material filed pursuant to Section
13(a) or 15(d) of the Exchange Act (all of the foregoing including filings
incorporated by reference therein being referred to herein as the "Commission

and complete copies of the Commission Documents filed with the SEC since October

according to applicable law, rule or regulation, should have been disclosed

connection with the transactions contemplated by this Agreement. As of their
respective filing dates, the Commission Documents complied in all material
respects with the requirements of the Exchange Act and the rules and regulations
of the SEC promulgated thereunder applicable to such documents, and, as of their
respective filing dates, none of the Commission Documents contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. The financial
statements of the Company included in the Commission Documents comply as to form
in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC or other applicable rules and
regulations with respect thereto. Such financial statements have been prepared
in accordance with generally accepted accounting principles ("GAAP") applied on

indicated in such financial statements or the notes thereto or (ii) in the case
of unaudited interim statements, to the extent they may not include footnotes or

exercisable for Common Stock within the six-month period next preceding the date
hereof, and the Company shall not permit any of its directors, officers or
affiliates directly or indirectly to take, any action (including, without
limitation, any offering or sale to any Person of the Shares or Warrants), so as
to make unavailable the exemption from Securities Act registration being relied
upon by the Company for the offer and sale to Investors of the Shares or the
Warrants (and the Warrant Shares) as contemplated by this Agreement.

all guaranties, endorsements and contingent obligations in respect of
Indebtedness of others, whether or not the same are or should be reflected in

subsidiaries has been and is presently being conducted in accordance with all
applicable federal, state and local governmental laws, rules, regulations and
ordinances, except as set forth in the SEC Documents or on Schedule 4.1(q)
hereto or such that do not cause a Material Adverse Effect. The Company and each
of its subsidiaries have all franchises, permits, licenses, consents and other
governmental or regulatory authorizations and approvals necessary for the
conduct of their respective businesses as now being conducted by them unless the
failure to possess such franchises, permits, licenses, consents and other
governmental or regulatory authorizations and approvals, individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect.

which it is required to file under applicable laws; all such Tax Returns are
true and accurate and have been prepared in compliance with all applicable laws;
the Company has paid all Taxes due and owing by it or any subsidiary (whether or
not such Taxes are required to be shown on a Tax Return) and have withheld and
paid over to the appropriate taxing authorities all Taxes which it is required
to withhold from amounts paid or owing to any employee, stockholder, creditor or
other third parties; and since October 31, 1999, the charges, accruals and
reserves for Taxes with respect to the Company (including any provisions for
deferred income taxes) reflected on the books of the Company are adequate to
cover any Tax liabilities of the Company if its current tax year were treated as
ending on the date hereof.

            No claim has been made by a taxing authority in a jurisdiction where
the Company does not file tax returns that the Company or any subsidiary is or
may be subject to taxation by that jurisdiction. There are no foreign, federal,
state or local tax audits or administrative or judicial proceedings pending or
being conducted with respect to the Company or any subsidiary; no information
related to Tax matters has been requested by any foreign, federal, state or
local taxing authority; and, except as disclosed above, no written notice
indicating an intent to open an audit or other review has been received by the
Company or any subsidiary from any foreign, federal, state or local taxing
authority. There are no material unresolved questions or claims concerning the
Company's Tax liability. The Company (A) has not executed or entered into a
closing agreement pursuant to Section 7121 of the Internal Revenue Code or any
predecessor provision thereof or any similar provision of state, local or
foreign law; and (B) has not agreed to or is required to make any adjustments

of state, local or foreign law by reason of a change in accounting method
initiated by the Company or any of its subsidiaries or has any knowledge that
the IRS has proposed any such adjustment or change in accounting method, or has
any application pending with any taxing authority requesting permission for any
changes in accounting methods that relate to the business or operations of the
Company. The Company has not been a United States real property holding
corporation within the meaning of Section 897(c)(2) of the Internal Revenue Code
during the applicable period specified in Section 897(c)(1)(A)(ii) of the
Internal Revenue Code.

            The Company has not made an election under Section 341(f) of the
Internal Revenue Code. The Company is not liable for the Taxes of another person
that is not a subsidiary of the

Company under (A) Treas. Reg. Section 1.1502-6 (or comparable provisions of
state, local or foreign law), (B) as a transferee or successor, (C) by contract
or indemnity or (D) otherwise. The Company is not a party to any tax sharing

members (collectively, the "Investor Indemnitees"), from and against any and all
Damages, and agrees to reimburse the Investor Indemnitees for all reasonable
out-of-pocket expenses (including the reasonable fees and expenses of legal
counsel), in each case promptly as incurred by the Investor Indemnitees and to
the extent arising out of or in connection with:

            (i) any misrepresentation, omission of fact or breach of any of the
      Company's representations or warranties contained in this Agreement, the
      annexes, schedules or exhibits hereto or any instrument, agreement or
      certificate entered into or delivered by the Company pursuant to this
      Agreement; or

            (ii) any failure by the Company to perform in any material respect
      any of its covenants, agreements, undertakings or obligations set forth in
      this Agreement, the annexes, schedules or exhibits hereto or any
      instrument, agreement or certificate entered into or delivered by the

directors, partners and members (collectively, the "Company Indemnitees"), from
and against any and all Damages, and agrees to reimburse the Company Indemnitees
for reasonable all out-of-pocket expenses (including the reasonable fees and

misrepresentation, omission of fact, or breach of any of the Investor's
representations or warranties contained in this Agreement, the annexes,
schedules or exhibits hereto or any instrument, agreement or certificate entered
into or delivered by the Investor pursuant to this Agreement. Notwithstanding
anything to the contrary herein, the Investor shall not be liable under this
Section 7.2(b) for any amount in excess of the net proceeds to such Investor as
a result of the sale of Registrable Securities pursuant to the Registration
Statement.

Section 7.3. Notice. Promptly after receipt by either party hereto seeking
indemnification pursuant to Section 7.2 (an "Indemnified Party") of written
notice of any investigation, claim, proceeding or other action in respect of
which indemnification is being sought (each, a "Claim"), the Indemnified Party
promptly shall notify the party from whom indemnification pursuant to Section
7.2 is being sought (the "Indemnifying Party") of the commencement thereof; but
the omission to so notify the Indemnifying Party shall not relieve it from any
liability that it otherwise may have to the Indemnified Party, except to the
extent that the Indemnifying Party is actually prejudiced by such omission or
delay. In connection with any Claim as to which both the Indemnifying Party and
the Indemnified Party are parties, the Indemnifying Party shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying Party, the Indemnified Party shall have the right to

Indemnified Party if (and only if): (x) the Indemnifying Party shall have agreed
to pay such fees, out-of-pocket costs and expenses, (y) the Indemnified Party
reasonably shall have concluded that representation of the Indemnified Party and
the Indemnifying Party by the same legal counsel would not be appropriate due to
actual or, as reasonably determined by legal counsel to the Indemnified Party,
potentially differing interests between such parties in the conduct of the
defense of such Claim, or if there may be legal defenses available to the
Indemnified Party that are in addition to or disparate from those available to
the Indemnifying Party, or (z) the Indemnifying Party shall have failed to
employ legal counsel reasonably satisfactory to the Indemnified Party within a
reasonable period of time after notice of the commencement of such Claim. If the
Indemnified Party employs separate legal counsel in circumstances other than as
described in clauses (x), (y) or (z) above, the fees, costs and expenses of such
legal counsel shall be borne exclusively by the Indemnified Party. Except as
provided above, the Indemnifying Party shall not, in connection with any Claim
in the same jurisdiction, be liable for the fees and expenses of more than one
firm of legal counsel for the Indemnified Party (together with appropriate local
counsel). The Indemnifying Party shall not, without the prior written consent of
the Indemnified Party (which consent shall not unreasonably be withheld), settle
or compromise any Claim or consent to the entry of any judgment that does not
include an unconditional release of the Indemnified Party from all liabilities
with respect to such Claim or judgment.

            All fees and expenses of the Indemnified Party (including reasonable
costs of defense and investigation in a manner not inconsistent with this
Section and all reasonable attorneys' fees and expenses) shall be paid to the
Indemnified Party, as incurred, within ten (10) Trading Days of written notice
thereof to the Indemnifying Party (regardless of whether it is ultimately
determined that an Indemnified Party is not entitled to indemnification
hereunder; provided, that the Indemnifying Party may require such Indemnified
Party to undertake to reimburse all such fees and expenses to the extent it is
finally judicially determined that such Indemnified Party is not entitled to
indemnification hereunder).

Section 7.4. Direct Claims. In the event one party hereunder should have a claim
for indemnification that does not involve a claim or demand being asserted by a
third party, the Indemnified Party promptly shall deliver notice of such claim
to the Indemnifying Party. If the Indemnified Party disputes the claim, such
dispute shall be resolved by mutual agreement of the Indemnified Party and the
Indemnifying Party or by binding arbitration conducted in accordance with the
procedures and rules of the American Arbitration Association as set forth in
Article X. Judgment upon any award rendered by any arbitrators may be entered in
any court having competent jurisdiction thereof.

                                  ARTICLE VIII

         DUE DILIGENCE REVIEW; NON-DISCLOSURE OF NON-PUBLIC INFORMATION.

Section 8.1. Due Diligence Review. Subject to Section 8.2, the Company shall
make available for inspection and review by the Investors, advisors to and
representatives of the Investors (who may or may not be affiliated with the
Investors and who are reasonably acceptable to the

                                       20

Company), any underwriter participating in any disposition of the Registrable
Securities on behalf of the Investors pursuant to the Registration Statement,
any such registration statement or amendment or supplement thereto or any blue
sky, Principal Market or other filing, all SEC Documents and other filings with
the SEC, and all other publicly available corporate documents and properties of
the Company as may be reasonably necessary for the purpose of such review, and
cause the Company's officers, directors and employees to supply all such
publicly available information reasonably requested by the Investors or any such
representative, advisor or underwriter in connection with such Registration
Statement (including, without limitation, in response to all questions and other
inquiries reasonably made or submitted by any of them), prior to and from time
to time after the filing and effectiveness of the Registration Statement for the
sole purpose of enabling the Investors and such representatives, advisors and
underwriters and their respective accountants and attorneys to conduct initial
and ongoing due diligence with respect to the Company and the accuracy of the
Registration Statement.

Section 8.2. Non-Disclosure of Non-Public Information.

      (a) The Company shall not disclose material non-public information to the
Investors, advisors to or representatives of the Investors unless prior to
disclosure of such information the Company identifies such information as being
non-public information and provides the Investors, such advisors and
representatives with the opportunity to accept or refuse to accept such
non-public information for review. Other than disclosure of any comment letters
received from the SEC staff with respect to the Registration Statement, the
Company may, as a condition to disclosing any non-public information hereunder,
require the Investors' advisors and representatives to enter into a
confidentiality agreement in form and content reasonably satisfactory to the
Company and the Investors.

      (b) Nothing herein shall require the Company to disclose material
non-public information to the Investors or their advisors or representatives,
and the Company represents that it does not disseminate material non-public
information to any investors who purchase stock in the Company in a public
offering, to money managers or to securities analysts, provided, however, that
notwithstanding anything herein to the contrary, the Company will, as
hereinabove provided, promptly notify the advisors and representatives of the
Investors and, if any, underwriters, of any event or the existence of any
circumstance (without any obligation to disclose the specific event or
circumstance) of which it becomes aware, constituting material non-public
information (whether or not requested of the Company specifically or generally
during the course of due diligence by such persons or entities), which, if not
disclosed in the prospectus included in the Registration Statement would cause
such prospectus to include a material misstatement or to omit a material fact
required to be stated therein in order to make the statements, therein in light
of the circumstances in which they were made, not misleading. Nothing contained
in this Section 8.2 shall be construed to mean that such persons or entities
other than the Investors (without the written consent of the Investors prior to
disclosure of such information as set forth in Section 8.2(a)) may not obtain
non-public information in the course of conducting due diligence in accordance
with the terms of this Agreement and nothing herein shall prevent any such
persons or entities from notifying the Company of their opinion that based on
such due diligence by such persons or entities, that the Registration Statement
contains an untrue statement of a material fact or omits a material fact
required to be stated in the

                                       21
<PAGE>   22
Registration Statement or necessary to make the statements contained therein, in
light of the circumstances in which they were made, not misleading.

                                  CHOICE OF LAW

Section 10.1. Governing Law/Arbitration. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York applicable to
contracts made in New York by persons domiciled in New York City and without
regard to its principles of conflicts of laws. Any dispute under this Agreement
shall be submitted to arbitration under the American Arbitration Association
(the "AAA") in New York City, New York, and shall be finally and conclusively
determined by the decision of a board of arbitration consisting of three (3)
members (hereinafter referred to as the "Board of Arbitration") selected
according to the rules governing the AAA. The Board of Arbitration shall meet on
consecutive business days in New York City, New York, and shall reach and render
a decision in writing (concurred in by a majority of the members of the Board of
Arbitration) with respect to the amount, if any, which the losing party is
required to pay to the other party in respect of a claim filed. In connection
with rendering its decisions, the Board of Arbitration shall adopt and follow
the laws of the State of New York unless the matter at issue is the corporation
law of the company's state of incorporation, in which event the corporation law
of such jurisdiction shall govern such issue. To the extent practical, decisions
of the Board of Arbitration shall be rendered no more than thirty (30) calendar
days following commencement of proceedings with respect thereto. The Board of
Arbitration shall cause its written decision to be delivered to all parties
involved in the dispute. Any decision made by the Board of Arbitration (either
prior to or after the expiration of such thirty (30) calendar day period) shall
be final, binding and conclusive on the parties to the dispute, and entitled to
be enforced to the fullest extent permitted by law and entered in any court of
competent jurisdiction. The Board of Arbitration shall be authorized and is
hereby directed to enter a default judgment against any party failing to
participate in any proceeding hereunder within the time periods set forth in the
AAA rules. The prevailing party shall be awarded its costs, including attorneys'
fees, from the non-prevailing party as part of the arbitration award. Any party
shall have the right to seek injunctive relief from any court of competent
jurisdiction in any case where such relief is available. The prevailing party in
such injunctive action shall be awarded its costs, including attorney's fees,
from the non-prevailing party.

Notwithstanding the foregoing, (a) the provisions of this Agreement shall inure
to the benefit of, and be enforceable by, any permitted transferee of any of the
Shares or Warrants purchased or acquired by any Investor hereunder with respect
to the Shares or Warrants held by such person, and (b) upon the prior written
consent of the Company, which consent shall not unreasonably be withheld or
delayed, each Investor's interest in this Agreement may be assigned at any time,
in whole or in part, to any other person or entity (including any Affiliate of
the Investor) who agrees to make the representations and warranties of such
Investor contained in Article III and who agrees to be bound by the terms of
this Agreement. Notwithstanding anything herein to the contrary, any such
transfers shall be in minimum denominations of 50,000 shares of Common Stock or
for 10,000 Warrant Shares.

Section 13.1. Counterparts/ Facsimile/ Amendments. This Agreement may be
executed in multiple counterparts, each of which may be executed by less than
all of the parties and shall be deemed to be an original instrument which shall
be enforceable against the parties actually executing such counterparts and all
of which together shall constitute one and the same instrument. Except as
otherwise stated herein, in lieu of the original documents, a facsimile
transmission or copy of the original documents shall be as effective and
enforceable as the original. This Agreement may be amended only by a writing
executed by all parties.

Section 13.2. Entire Agreement. This Agreement, the agreements attached as
Exhibits hereto, which, include but are not limited to the Warrants, the Escrow

supersedes all prior and contemporaneous agreements, negotiations and
understandings between the parties, both oral and written relating to the
subject matter hereof. The terms and conditions of all Exhibits to this
Agreement are incorporated herein by this reference and shall constitute part of
this Agreement as is fully set forth herein.

Section 13.3. Severability. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that such severability shall be ineffective if
it materially changes the economic benefit of this Agreement to any party.

Section 13.4. Number and Gender. There may be one or more Investors parties to
this Agreement, which Investors may be natural persons or entities. All
references to plural Investors shall apply equally to a single Investor if there

certificate, upon delivery of an indemnity agreement or security reasonably
satisfactory in form to the Company (which shall not include the positing of any

                          REGISTRATION RIGHTS AGREEMENT

            THIS REGISTRATION RIGHTS AGREEMENT, dated as of September 20, 2000
between the investor or investors signatory hereto (each an "Investor" and
together the "Investors"), and Bionutrics, Inc., an Nevada corporation (the
"Company").

            WHEREAS, simultaneously with the execution and delivery of this
Agreement, the Investors are committing to purchasing from the Company, pursuant
to a Common Stock and Warrants Purchase Agreement dated the date hereof (the
"Purchase Agreement"), 500,000 shares of Common Stock and Warrants (terms not
defined herein shall have the meanings ascribed to them in the Purchase
Agreement); and

            WHEREAS, the Company desires to grant to the Investors the
registration rights set forth herein with respect to the Shares purchased
pursuant to the Purchase Agreement, the shares of Common Stock issued as payment
of fees to the Investors, the shares of Common Stock issued as payment of
liquidated damages to the Investors and shares of Common Stock issuable upon
exercise of the Warrants (the "Securities").

            NOW, THEREFORE, the parties hereto mutually agree as follows:

            Section 1. Registrable Securities. As used herein the term
"Registrable Security" means the Securities until (i) the Registration Statement
has been declared effective by the SEC, and all Securities have been disposed of
pursuant to the Registration Statement, (ii) all Securities have been sold under
circumstances under which all of the applicable conditions of Rule 144 (or any
similar provision then in force) under the Securities Act ("Rule 144") are met,
(iii) all Securities have been otherwise transferred to holders who may trade
such Securities without restriction under the Securities Act, and the Company
has delivered a new certificate or other evidence of ownership for such
Securities not bearing a restrictive legend or (iv) such time as, in the opinion
of counsel to the Company, all Securities may be sold without any time, volume
or manner limitations pursuant to Rule 144(k) (or any similar provision then in
effect) under the Securities Act. The term "Registrable Securities" means any
and/or all of the securities falling within the foregoing definition of a
"Registrable Security." In the event of any merger, reorganization,
consolidation, recapitalization or other change in corporate structure affecting
the Common Stock, such adjustment shall be deemed to be made in the definition
of "Registrable Security" as is appropriate in order to prevent any dilution or
enlargement of the rights granted pursuant to this Agreement.

            Section 2. Restrictions on Transfer. Each Investor acknowledges and
understands that prior to the registration of the Securities as provided herein,
the Securities are "restricted securities" as defined in Rule 144 promulgated
under the Securities Act. Each Investor understands that no disposition or
transfer of the Securities may be made by Investor in the absence of (i) an
opinion of counsel to the Investor, in form and substance reasonably

                                       1
<PAGE>   2
satisfactory to the Company, that such transfer may be made without registration
under the Securities Act, pursuant to Regulation S or another exemption, or (ii)
such registration.

                  With a view to making available to the Investors the benefits
of Rule 144 under the Securities Act or any other similar rule or regulation of
the SEC that may at any time permit the Investors to sell securities of the
Company to the public without registration the Company agrees to:

                  (a) comply with the provisions of paragraph (c)(1) of Rule
144; and

                  (b) file with the SEC in a timely manner all reports and other
documents required to be filed with the SEC pursuant to Section 13 or 15(d)
under the Exchange Act by companies subject to either of such sections,
irrespective of whether the Company is then subject to such reporting
requirements.

            Section 3. Registration Rights With Respect to the Securities.

                  (a) The Company agrees that it will prepare and file with the
SEC, within forty-five (45) days of the Closing, a registration statement (on
Form S-3 or S-1 or other appropriate form of registration statement) under the
Securities Act (the "Registration Statement"), at the sole expense of the
Company (except as provided in Section 3(c) hereof), so as to permit a public
offering and resale of the Securities under the Securities Act by the Investors.

                  The Company shall use its best efforts to cause such
Registration Statement to become effective within ninety (90) days from the
Closing Date or, if earlier, within five (5) days of SEC clearance and will
within said five (5) days request acceleration of effectiveness. The number of
shares designated in the Registration Statement to be registered shall be all of
the Securities and, at the time of filing the Registration Statement, and shall
include appropriate language regarding reliance upon Rule 416 to the extent
permitted by the SEC. The Company will notify Investors of the effectiveness of
the Registration Statement within one (1) Trading Day of such event. In the
event that the number of shares so registered shall for any reason prove to be
insufficient to register the resale of all of the Securities, then the Company
shall be obligated to file, within fifteen (15) days of notice from any
Investor, a further Registration Statement registering such remaining shares and
shall use diligent best efforts to prosecute such additional Registration
Statement to effectiveness within seventy-five (75) days of the date of such
notice.

                  (b) The Company will maintain the Registration Statement or
post-effective amendment filed under this Section 3 effective under the
Securities Act until the earlier of (i) the date that all of the Securities have
been sold pursuant to such Registration Statement, (ii) the date the Investors
receive an opinion of counsel to the Company, which counsel shall be reasonably
acceptable to the Investors, that the Securities may be sold under the
provisions of Rule 144 without limitation as to volume, (iii) the date when all
Securities have been otherwise transferred to persons who may trade such shares
without restriction under the Securities Act, and the Company has delivered a
new certificate or other evidence of ownership for such

                                       2
<PAGE>   3
securities not bearing a restrictive legend, (iv) two (2) years from the
Effective Date, or (v) the date when all Securities may be sold without any
time, volume or manner limitations pursuant to Rule 144(k) or any similar
provision then in effect under the Securities Act in the opinion of counsel to
the Company, which counsel shall be reasonably acceptable to the Investor (the
"Effectiveness Period").

                  (c) All fees, disbursements and out-of-pocket expenses and
costs incurred by the Company in connection with the preparation and filing of
the Registration Statement under subparagraph 3(a) and in complying with
applicable securities and Blue Sky laws (including, without limitation, all
attorneys' fees of the Company) shall be borne by the Company. The Investors
shall bear the cost of underwriting and/or brokerage discounts, fees and
commissions, if any, applicable to the Securities being registered and the fees
and expenses of their counsel. The Investors and their counsel shall have a
reasonable period, not to exceed five (5) Trading Days, to review the proposed
Registration Statement or any amendment thereto, prior to filing with the SEC,
and the Company shall provide each Investor with copies of any comment letters
received from the SEC with respect thereto within two (2) Trading Days of
receipt thereof. The Company shall qualify any of the securities for sale in
such states as any Investor reasonably designates and shall furnish
indemnification in the manner provided in Section 6 hereof. However, the Company
shall not be required to qualify in any state which will require an escrow or
other restriction relating to the Company and/or the sellers, or which will
require the Company to qualify to do business in such state or require the
Company to file therein any general consent to service of process. The Company
at its expense will supply the Investors with copies of the applicable
Registration Statement and the prospectus included therein and other related
documents in such quantities as may be reasonably requested by the Investors.

                  (d) The Company shall not be required by this Section 3 to
include an Investor's Securities in any Registration Statement which is to be
filed if, in the opinion of counsel for both the Investor and the Company (or,
should they not agree, in the opinion of another counsel experienced in
securities law matters acceptable to counsel for the Investor and the Company)
the proposed offering or other transfer as to which such registration is
requested is exempt from applicable federal and state securities laws and would
result in all purchasers or transferees obtaining securities which are not
"restricted securities", as defined in Rule 144.

                  (e) In the event that (i) the Registration Statement to be
filed by the Company pursuant to Section 3(a) above is not filed with the SEC
within forty-five (45) days from Closing Date, (ii) such Registration Statement
is not declared effective by the SEC within the earlier of ninety (90) days from
the Closing Date or five (5) days of clearance by the SEC and the request of
effectiveness, (iii) such Registration Statement is not maintained as effective
by the Company for the period set forth in Section 3(b) above or (iv) the
additional Registration Statement referred to in Section 3(a) is not filed
within fifteen (15) days or declared effective within seventy-five (75) days as
set forth therein (each a "Registration Default") then the Company will pay
Investor (pro rated on a daily basis), as liquidated damages for such failure
and not as a penalty, the sum of (i) in the event of late filing (in the case of
clause (1) and (iv) above), two percent (2%) of the purchase price of the shares
of Common Stock purchased from the Company and held by the Investor for each
month until such Registration Statement has been

                                       3
<PAGE>   4
filed, and (ii) in the event of late effectiveness (in case of clause (ii)
above) or lapsed effectiveness (in the case of clause (iii) and (iv) above), two
percent (2%) of the purchase price of the shares of Common Stock purchased from
the Company and held by the Investor for each month (regardless of whether one
or more such Registration Defaults are then in existence) until such
Registration Statement has been declared effective. Such payment of the
liquidated damages shall be made to the Investors in cash or in shares of Common
Stock, as elected by each Investor in is discretion, within five (5) calendar
days of demand, provided, however, that the payment of such liquidated damages
shall not relieve the Company from its obligations to register the Securities
pursuant to this Section. The market value of the Common Stock for this purpose
shall be the closing price (or last trade, if so reported) on the Principal
Market for each day during such Registration Default.

                  If the Company does not remit the payment to the Investors as
set forth above, the Company will pay the Investors reasonable costs of
collection, including attorneys' fees, in addition to the liquidated damages.
The registration of the Securities pursuant to this provision shall not affect
or limit the Investors' other rights or remedies as set forth in this Agreement.

                  (f) No provision contained herein shall preclude the Company
from selling securities pursuant to any Registration Statement in which it is
required to include Securities pursuant to this Section 3.

                  (g) If at any time or from time to time after the effective
date of any Registration Statement, the Company notifies the Investors in
writing of the existence of a Potential Material Event (as defined in Section
3(h) below), the Investors shall not offer or sell any Securities or engage in
any other transaction involving or relating to Securities, from the time of the
giving of notice with respect to a Potential Material Event until the Investors
receive written notice from the Company that such Potential Material Event
either has been disclosed to the public or no longer constitutes a Potential
Material Event; provided, however, that the Company may not so suspend the right
to such holders of Securities for more than twenty (20) Trading Days in the
aggregate during any twelve month period, during the period the Registration
Statement is required to be in effect, and if such period is exceeded, such
event shall be a Registration Default. If a Potential Material Event shall occur
prior to the date a Registration Statement is required to be filed, then the
Company's obligation to file such Registration Statement shall be delayed
without penalty for not more than thirty (30) days, and such delay or delays
shall not constitute a Registration Default. The Company must, if lawful, give
the Investors notice in writing at least two (2) Trading Days prior to the first
day of the blackout period.

                  (h) "Potential Material Event" means any of the following: (a)
the possession by the Company of material information that is not ripe for
disclosure in a registration statement, as determined in good faith by the Chief
Executive Officer or the Board of Directors of the Company or that disclosure of
such information in a Registration Statement would be detrimental to the
business and affairs of the Company; or (b) any material engagement or activity
by the Company which would, in the good faith determination of the Chief
Executive Officer or the Board of Directors of the Company, be adversely
affected by disclosure in a

                                       4
<PAGE>   5
registration statement at such time, which determination shall be accompanied by
a good faith determination by the Chief Executive Officer or the Board of
Directors of the Company that the applicable Registration Statement would be
materially misleading absent the inclusion of such information.

            Section 4. Cooperation with Company. The Investors will cooperate
with the Company in all respects in connection with this Agreement, including
timely supplying all information reasonably requested by the Company (which
shall include all information regarding the Investors and proposed manner of
sale of the Registrable Securities required to be disclosed in any Registration
Statement) and executing and returning all documents reasonably requested in
connection with the registration and sale of the Registrable Securities and
entering into and performing their obligations under any underwriting agreement,
if the offering is an underwritten offering, in usual and customary form, with
the managing underwriter or underwriters of such underwritten offering. Nothing
in this Agreement shall obligate any Investor to consent to be named as an
underwriter in any Registration Statement. The obligation of the Company to
register the Registrable Securities shall be absolute and unconditional as to
those Securities which the SEC will permit to be registered without naming the
Investors as underwriters. Any delay or delays caused by the Investors by
failure to cooperate as required hereunder shall not constitute a Registration
Default.

            Section 5. Registration Procedures. If and whenever the Company is
required by any of the provisions of this Agreement to effect the registration
of any of the Registrable Securities under the Securities Act, the Company shall
(except as otherwise provided in this Agreement), as expeditiously as possible,
subject to the Investors' assistance and cooperation as reasonably required with
respect to each Registration Statement:

                  (a) (i) prepare and file with the SEC such amendments and
supplements to the Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective and
to comply with the provisions of the Securities Act with respect to the sale or
other disposition of all securities covered by such registration statement
whenever the Investors shall desire to sell or otherwise dispose of the same
(including prospectus supplements with respect to the sales of securities from
time to time in connection with a registration statement pursuant to Rule 415
promulgated under the Securities Act) and (ii) take all lawful action such that
each of (A) the Registration Statement and any amendment thereto does not, when
it becomes effective, contain 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, in light of the circumstances under which they were made,
not misleading and (B) the prospectus forming part of the Registration
Statement, and any amendment or supplement thereto, does not at any time during
the Registration Period 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, in light of the circumstances under which they were made,
not misleading;

                  (b) (i) prior to the filing with the SEC of any Registration
Statement (including any amendments thereto) and the distribution or delivery of
any prospectus (including any supplements thereto), provide draft copies thereof
to the Investors as required by Section

                                       5
<PAGE>   6
3(c) and reflect in such documents all such comments as the Investors (and their
counsel) reasonably may propose and (ii) furnish to each Investor such numbers
of copies of a prospectus including a preliminary prospectus or any amendment or
supplement to any prospectus, as applicable, in conformity with the requirements
of the Securities Act, and such other documents, as such Investor may reasonably
request in order to facilitate the public sale or other disposition of the
securities owned by such Investor;

                  (c) register and qualify the Registrable Securities covered by
the Registration Statement under such other securities or blue sky laws of such
jurisdictions as the Investors shall reasonably request (subject to the
limitations set forth in Section 3(c) above), and do any and all other acts and
things which may be necessary or advisable to enable each Investor to consummate
the public sale or other disposition in such jurisdiction of the securities
owned by such Investor;

                  (d) list such Registrable Securities on the Principal Market,
if the listing of such Registrable Securities is then permitted under the rules
of such Principal Market;

                  (e) notify each Investor at any time when a prospectus
relating thereto covered by the Registration Statement is required to be
delivered under the Act, of the happening of any event of which it has knowledge
as a result of which the prospectus included in the Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits 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 then
existing, and the Company shall prepare and file a curative amendment under
Section 5(a) as quickly as commercially possible;

                  (f) as promptly as practicable after becoming aware of such
event, notify each Investor who holds Registrable Securities being sold (or, in
the event of an underwritten offering, the managing underwriters) of the
issuance by the SEC of any stop order or other suspension of the effectiveness
of the Registration Statement at the earliest possible time and take all lawful
action to effect the withdrawal, recission or removal of such stop order or
other suspension;

                  (g) cooperate with the Investors to facilitate the timely
preparation and delivery of certificates for the Registrable Securities to be
offered pursuant to the Registration Statement and enable such certificates for
the Registrable Securities to be in such denominations or amounts, as the case
may be, as the Investors reasonably may request and registered in such names as
the Investors may request; and, within three (3) Trading Days after a
Registration Statement which includes Registrable Securities is declared
effective by the SEC, deliver and cause legal counsel selected by the Company to
deliver to the transfer agent for the Registrable Securities (with copies to the
Investors) an appropriate instruction and, to the extent necessary, an opinion
of such counsel;

                  (h) take all such other lawful actions reasonably necessary to
expedite and facilitate the disposition by the Investors of their Registrable
Securities in accordance with the intended methods therefor provided in the
prospectus which are customary for issuers to perform under the circumstances;

                                       6
<PAGE>   7
                  (i) in the event of an underwritten offering, promptly include
or incorporate in a prospectus supplement or post-effective amendment to the
Registration Statement such information as the managers reasonably agree should
be included therein and to which the Company does not reasonably object and make
all required filings of such prospectus supplement or post-effective amendment
as soon as practicable after it is notified of the matters to be included or
incorporated in such prospectus supplement or post-effective amendment; and

                  (j)   maintain a transfer agent for its Common Stock.

            Section 6.  Indemnification.

                  (a) To the maximum extent permitted by law, the Company agrees
to indemnify and hold harmless the Investors and each person, if any, who
controls an Investor within the meaning of the Securities Act (each a
"Distributing Investor") against any losses, claims, damages or liabilities,
joint or several (which shall, for all purposes of this Agreement, include, but
not be limited to, all reasonable costs of defense and investigation and all
reasonable attorneys' fees and expenses), to which the Distributing Investor may
become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of any material
fact contained in any Registration Statement, or any related final prospectus or
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading; provided,
however, that the Company will not be liable in any such case to the extent, and
only to the extent, that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in such Registration Statement, preliminary prospectus,
final prospectus or amendment or supplement thereto in reliance upon, and in
conformity with, written information furnished to the Company by the
Distributing Investor, its counsel, affiliates or any underwriter specifically
for use in the preparation thereof. This Section 6(a) shall not inure to the
benefit of any Distributing Investor with respect to any person asserting such
loss, claim, damage or liability who purchased the Registrable Securities which
are the subject thereof if the Distributing Investor failed to send or give (in
violation of the Securities Act or the rules and regulations promulgated
thereunder) a copy of the prospectus contained in such Registration Statement to
such person at or prior to the written confirmation to such person of the sale
of such Registrable Securities, where the Distributing Investor was obligated to
do so under the Securities Act or the rules and regulation promulgated
thereunder. This indemnity agreement will be in addition to any liability which
the Company may otherwise have.

                  (b) To the maximum extent permitted by law, each Distributing
Investor agrees that it will indemnify and hold harmless the Company, and each
officer and director of the Company or person, if any, who controls the Company
within the meaning of the Securities Act, against any losses, claims, damages or
liabilities (which shall, for all purposes of this Agreement, include, but not
be limited to, all reasonable costs of defense and investigation and all
reasonable attorneys' fees and expenses) to which the Company or any such
officer, director or controlling person may become subject under the Securities
Act or otherwise, insofar

                                       7
<PAGE>   8
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained in any Registration Statement, or any related
final prospectus or amendment or supplement thereto, or arise out of or are
based upon the omission or the alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, but in each case only to the extent that such untrue statement or
alleged untrue statement or omission or alleged omission was made in such
Registration Statement, final prospectus or amendment or supplement thereto in
reliance upon, and in conformity with, written information furnished to the
Company by such Distributing Investor, its counsel, affiliates or any
underwriter specifically for use in the preparation thereof. This indemnity
agreement will be in addition to any liability which the Distributing Investor
may otherwise have. Notwithstanding anything to the contrary herein, the
Distributing Investor shall be liable under this Section 6(b) for only that
amount as does not exceed the net proceeds to such Distributing Investor as a
result of the sale of Registrable Securities pursuant to the Registration
Statement.

                  (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action against such indemnified
party, such indemnified party will, if a claim in respect thereof is to be made
against the indemnifying party under this Section 6, notify the indemnifying
party in writing of the commencement thereof; but the omission so to notify the
indemnifying party will not relieve the indemnifying party from any liability
which it may have to any indemnified party except to the extent the failure of
the indemnified party to provide such written notification actually prejudices
the ability of the indemnifying party to defend such action. In case any such
action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate in, and, to the extent that it may wish, jointly with
any other indemnifying party similarly notified, assume the defense thereof,
subject to the provisions herein stated and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party will not be liable to such indemnified party
under this Section 6 for any legal or other expenses subsequently incurred by
such indemnified party in connection with the defense thereof other than
reasonable costs of investigation, unless the indemnifying party shall not
pursue the action to its final conclusion. The indemnified parties as a group
shall have the right to employ one separate counsel in any such action and to
participate in the defense thereof, but the fees and expenses of such counsel
shall not be at the expense of the indemnifying party if the indemnifying party
has assumed the defense of the action with counsel reasonably satisfactory to
the indemnified party unless (i) the employment of such counsel has been
specifically authorized in writing by the indemnifying party, or (ii) the named
parties to any such action (including any impleaded parties) include both the
indemnified party and the indemnifying party and the indemnified party shall
have been advised by its counsel that there may be one or more legal defenses
available to the indemnifying party different from or in conflict with any legal
defenses which may be available to the indemnified party or any other
indemnified party (in which case the indemnifying party shall not have the right
to assume the defense of such action on behalf of such indemnified party, it
being understood, however, that the indemnifying party shall, in connection with
any one such action or separate but substantially similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances, be liable only for the reasonable fees and expenses of one
separate firm of attorneys for the indemnified party, which firm shall be
designated in

                                       8
<PAGE>   9
writing by the indemnified party). No settlement of any action against an
indemnified party shall be made without the prior written consent of the
indemnified party, which consent shall not be unreasonably withheld so long as
such settlement includes a full release of claims against the indemnified party.

            All fees and expenses of the indemnified party (including reasonable
costs of defense and investigation in a manner not inconsistent with this
Section and all reasonable attorneys' fees and expenses) shall be paid to the
indemnified party, as incurred, within ten (10) Trading Days of written notice
thereof to the indemnifying party (regardless of whether it is ultimately
determined that an indemnified party is not entitled to indemnification
hereunder; provided, that the indemnifying party may require such indemnified
party to undertake to reimburse all such fees and expenses to the extent it is
finally judicially determined that such indemnified party is not entitled to
indemnification hereunder).

            Section 7. Contribution. In order to provide for just and equitable
contribution under the Securities Act in any case in which (i) the indemnified
party makes a claim for indemnification pursuant to Section 6 hereof but is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any indemnified party, then the Company and the
applicable Distributing Investor shall contribute to the aggregate losses,
claims, damages or liabilities to which they may be subject (which shall, for
all purposes of this Agreement, include, but not be limited to, all reasonable
costs of defense and investigation and all reasonable attorneys' fees and
expenses), in either such case (after contribution from others) on the basis of
relative fault as well as any other relevant equitable considerations. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the applicable Distributing Investor on the other
hand, and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Distributing Investor agree that it would not be just and equitable if
contribution pursuant to this Section 7 were determined by pro rata allocation
or by any other method of allocation which does not take account of the
equitable considerations referred to in this Section 7. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section 7
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.

      Notwithstanding any other provision of this Section 7, in no event shall
any (i) Investor be required to undertake liability to any person under this
Section 7 for any amounts in excess of the dollar amount of the proceeds
received by such Investor from the sale of such Investor's Registrable
Securities (after deducting any fees, discounts and commissions applicable
thereto)

                                       9
<PAGE>   10
pursuant to any Registration Statement under which such Registrable Securities
are registered under the Securities Act and (ii) underwriter be required to
undertake liability to any person hereunder for any amounts in excess of the
aggregate discount, commission or other compensation payable to such underwriter
with respect to the Registrable Securities underwritten by it and distributed
pursuant to such Registration Statement.

            Section 8. Notices. All notices, demands, requests, consents,
approvals, and other communications required or permitted hereunder shall be in
writing and shall be delivered as set forth in the Purchase Agreement.

            Section 9. Assignment. This Agreement is binding upon and inures to
the benefit of the parties hereto and their respective heirs, successors and
permitted assigns. The rights granted the Investors under this Agreement may be
assigned to any purchaser of substantially all of the Registrable Securities (or
the rights thereto) from an Investor, as otherwise permitted by the Purchase
Agreement.

            Section 10. Additional Covenants of the Company. The Company agrees
that at such time as it otherwise meets the requirements for the use of
Securities Act Registration Statement on Form S-3 for the purpose of registering
the Registrable Securities, it shall file all reports and information required
to be filed by it with the SEC in a timely manner and take all such other action
so as to maintain such eligibility for the use of such form.

            Section 11. Counterparts/Facsimile. This Agreement may be executed
in two or more counterparts, each of which shall constitute an original, but all
of which when together shall constitute but one and the same instrument, and
shall become effective when one or more counterparts have been signed by each
party hereto and delivered to the other parties. In lieu of the original, a
facsimile transmission or copy of the original shall be as effective and
enforceable as the original.

            Section 12. Remedies/Severability. The remedies provided in this
Agreement are cumulative and not exclusive of any remedies provided by law. If
any term, provision, covenant or restriction of this Agreement is held by a
court of competent jurisdiction to be invalid, illegal, void or unenforceable,
the remainder of the terms, provisions, covenants and restrictions set forth
herein shall remain in full force and effect and shall in no way be affected,
impaired or invalidated, and the parties hereto shall use their best efforts to
find and employ an alternative means to achieve the same or substantially the
same result as that contemplated by such term, provision, covenant or
restriction.

            Section 13. Conflicting Agreements. The Company shall not enter into
any agreement with respect to its securities that is inconsistent with the
rights granted to the holders of Registrable Securities in this Agreement or
otherwise prevents the Company from complying with all of its obligations
hereunder.

            Section 14.  Headings.  The headings in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

            Section 15. Governing Law, Arbitration. This Agreement shall be
governed by and construed in accordance with the laws of the State of New York
applicable to contracts made in New York by persons domiciled in New York City
and without regard to its principles of conflicts of laws. Any dispute under
this Agreement shall be submitted to arbitration under the American Arbitration
Association (the "AAA") in New York City, New York, and shall be finally and
conclusively determined by the decision of a board of arbitration consisting of
three (3) members (hereinafter referred to as the "Board of Arbitration")
selected as according to the rules governing the AAA. The Board of Arbitration
shall meet on consecutive business days in New York City, New York, and shall
reach and render a decision in writing (concurred in by a majority of the
members of the Board of Arbitration) with respect to the amount, if any, which
the losing party is required to pay to the other party in respect of a claim
filed. In connection with rendering its decisions, the Board of Arbitration
shall adopt and follow the laws of the State of New York. To the extent
practical, decisions of the Board of Arbitration shall be rendered no more than
thirty (30) calendar days following commencement of proceedings with respect
thereto. The Board of Arbitration shall cause its written decision to be
delivered to all parties involved in the dispute. Any decision made by the Board
of Arbitration (either prior to or after the expiration of such thirty (30)
calendar day period) shall be final, binding and conclusive on the parties to
the dispute, and entitled to be enforced to the fullest extent permitted by law
and entered in any court of competent jurisdiction. The Board of Arbitration
shall be authorized and is hereby directed to enter a default judgment against
any party failing to participate in any proceeding hereunder within the time
periods set forth in the AAA rules. The prevailing party shall be awarded its
costs, including attorneys' fees, from the non-prevailing party as part of the
arbitration award. Any party shall have the right to seek injunctive relief from
any court of competent jurisdiction in any case where such relief is available.
The prevailing party in such injunctive action shall be awarded its costs,
including attorney's fees, from the non-prevailing party.

            IN WITNESS WHEREOF, the parties hereto have caused this Registration
Rights Agreement to be duly executed, on this 20th day of September, 2000.
