         THIS SECOND AMENDMENT TO RIGHTS AGREEMENT (this "Amendment") is made as
of the 7th day of August, 2000, by and between SYSTEMONE INDUSTRIES INC., a
Florida corporation (the "Company"), and CONTINENTAL STOCK TRANSFER & TRUST
COMPANY (the "Rights Agent").

                                    RECITALS

         WHEREAS, on October 1, 1998, the Board of Directors of the Company
authorized and declared a dividend distribution of one Right for each share of
common stock, $.001 par value, of the Company outstanding at the close of
business on October 8, 1998; and

         WHEREAS, the Company and the Rights Agent entered into a certain Rights
Agreement, dated as of October 1, 1998 (the "Rights Agreement"), providing,
among other things, for the issuance of the Rights (all capitalized terms used
in this Amendment and not otherwise defined herein shall have the meanings
ascribed to such terms in the Rights Agreement); and

         WHEREAS, the Company and the Rights Agent amended the Rights Agreement
pursuant to the First Amendment to Rights Agreement, dated as of May 24, 2000;
and

         WHEREAS, the Board of Directors of the Company has approved a second
amendment to the Rights Agreement as hereinafter set forth, pursuant to a
unanimous written consent dated as of August 7, 2000;

         NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1. Section 1 of the Rights Agreement is hereby amended by deleting the
definition of "Acquiring Person" set forth in subsection (a) thereof in its
entirety and substituting therefor a new definition of "Acquiring Person" to
read as follows:

         "Acquiring Person" shall mean any Person who or which, together with
         all Affiliates and Associates of such Person, shall be the Beneficial
         Owner of fifteen percent (15%) or more of the shares of Common Stock
         outstanding. Notwithstanding the foregoing, the term "Acquiring Person"
         shall not include (i) the Company, any Subsidiary of the Company, any
         employee benefit plan of the Company or of any Subsidiary of the
         Company, or any Person or entity organized, appointed or established by
         the Company for or pursuant to the terms of any such plan, (ii) Pierre
         G. Mansur, unless such individual shall be the beneficial owner of
         fifty percent (50%) or more of the shares of Common Stock then
         outstanding, (iii)

<PAGE>   2

         Hanseatic Americas LDC, unless it shall be the beneficial owner of
         forty-five percent (45%) or more of the shares of Common Stock then
         outstanding, (iv) Environmental Opportunities Fund II (Institutional),
         L.P., Environmental Opportunities Fund II, L.P., Environmental
         Opportunities Fund, L.P., or Environmental Opportunities Fund II
         (Cayman), L.P., unless such Persons shall be the Beneficial Owners,
         individually or in the aggregate, of thirty-five percent (35%) or more
         of the shares of Common Stock then outstanding, or (v) any Person who
         or which, together with all Affiliates and Associates of such Person,
         would be an Acquiring Person solely by reason of a reduction in the
         number of issued and outstanding shares of Common Stock of the Company
         pursuant to a transaction or series of related transactions approved by
         a majority of the Independent Directors, if any, then in office and
         approved by a Supermajority Vote; provided, further, however, that in
         the event that such Person described in the foregoing clause (v) does
         not become an Acquiring Person by reason of the foregoing clause (v),
         such Person shall nonetheless become an Acquiring Person in the event
         such Person thereafter acquires Beneficial Ownership of an additional
         one percent (1%) of the Common Stock of the Company, unless such
         additional Common Stock ownership results solely from a subsequent
         reduction in the number of issued and outstanding shares of Common
         Stock of the Company.

         2. Except as specifically amended hereby, the Rights Agreement is and
remains unmodified and in full force and effect and is hereby ratified and
confirmed.

         3. This Amendment shall be deemed a contract made under the laws of the
State of Florida and for all purposes shall be governed by and construed in
accordance with the laws of such State applicable to contracts made and to be
performed entirely within such State.

         4. This Amendment may be executed in counterparts, each of which shall
for all purposes be deemed to be an original, and shall constitute but one and
the same instrument.

                                        2

number of days elapsed (including the first day but excluding the last day)

under the Notes shall be due on a day other than a Business Day, such payment
shall be made on the next succeeding Business Day, and such extension of time
shall in such case be included in the computation of payment of interest. All
payments received by the Lenders, or any of them, shall be applied, first, to
the payment of interest, fees and expenses, with any balance to the payment and
reduction of principal. All payments made by the Borrower under the Notes shall
be made irrespective of, and without any reduction for, any set-off or
counterclaims. Notwithstanding any other provision contained in this Agreement,
the Borrower shall not make any payment on account of principal of or interest
on any Note unless payment is contemporaneously made on account of all Notes pro
rata on the basis of the respective Proportionate Shares of the Lenders.

or ratio with respect to any such securities pursuant to any anti-dilution
provisions thereunder, nor as a result of any such event, will the number of

                                      -14-

case may be, be subject to adjustment. No such conversion or exercise price or
ratio will be subject to adjustment as a consequence of the consummation of the
transactions contemplated by this Agreement, nor, as a consequence of such
consummation, will the numbers of shares of capital stock issuable upon such
conversion or such exercise, as the case may be, be subject to adjustment,
except that as a consequence of consummation of the transaction hereunder the
Series B Convertible Preferred Stock, the Series C Convertible Preferred Stock
and the Series D Convertible Preferred Stock, and the warrants issued in

statements therein, in light of the circumstances under which they were made,
not misleading. The financial statements of the Borrower included in the SEC
Documents comply as to form in all material respects with applicable accounting
requirements and the published rules and regulations of the Commission or other
applicable rules and regulations with respect thereto. Such financial statements
have been prepared in accordance with Generally Accepted Accounting Principles
applied on a consistent basis during the periods involved (except (i) as may be
otherwise indicated in such financial statements or the notes thereto or (ii)
the case of unaudited interim statements, to the extent they may not include
footnotes or may be condensed or summary statements) and fairly present in all
material respects the financial position of the Borrower as of the dates thereof
and the results of operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit
adjustments).

         Section 4.7 TAXES. Except as set forth on Schedule 4.7 annexed hereto,
the Borrower has filed or caused to be filed all federal, state, municipal,
foreign and other tax returns, reports and declarations, or extensions therefor,
required to be filed by it, so as to prevent any valid lien, charge or
encumbrance of any nature on its assets or properties and, except as set forth
on Schedule 4.7 annexed hereto, has paid or shall pay all taxes which have been
or shall become due with respect to the periods covered by said returns or
pursuant to any assessment received by it in connection therewith, which lien,
charge, encumbrance or failure to pay would, individually, or in the aggregate,
have a Material Adverse Effect. Except as set forth on Schedule 4.7 annexed
hereto, all assessments and charges (including penalties and interest, if any)
related to periods ended on or before December 31, 1999 have been or will be
paid by the Borrower, including any necessary adjustments with state and local
tax authorities, the failure to pay which would, individually, or in the
aggregate, have a Material Adverse Effect, and except as set forth on Schedule
4.7 annexed hereto, no material deficiency in payment of any taxes for any
period has been asserted by any taxing authority which remains unsettled at the
date hereof.

         Section 4.8 TITLE; CREDIT ARRANGEMENTS; DEFAULTS. The Borrower has
good, valid, and marketable title to all assets and properties owned by it and
material to its business, in each case free and clear of all Liens other than
(i) Liens created pursuant to the Capital Indebtedness, (ii) Liens in favor of
the Lenders, and (iii) Liens specifically permitted by the Lenders in writing,
and, without limiting the foregoing, the assets and properties owned by the
Borrower and shown on the consolidated balance sheet as of and at March 31, 2000
included in the SEC Documents which are, individually, or in the aggregate,
material to the Borrower's business or condition, are owned by the Borrower, in
each case free and clear of all Liens other than (i) Liens created pursuant to
the Capital Indebtedness, (ii) Liens in favor of the Lenders, and (iii) Liens
specifically permitted by the Lenders in writing. The Borrower leases or owns
all material properties and assets necessary for the operation of its business
as currently conducted. Set forth on Schedule 4.8 attached hereto is a list of
all contracts, agreements, mortgages, arrangements (written or oral), and other

                                      -16-
<PAGE>   21

documents to which the Borrower is a party or by which the Borrower or any of
its assets or properties is or may be bound, with respect to obligations of the
Borrower for borrowed money or guaranties therefor, or any restriction on the
repayment of indebtedness incurred or on the payment of dividends on any
securities of any such entity. No event has occurred, or, is alleged to have
occurred, which constitutes or with lapse of time or giving of notice or both,
would constitute a default or a basis for a claim of FORCE MAJEURE or other
claim of excusable delay or non-performance under any of the foregoing; and no
such event has occurred, or is alleged to have occurred, under any other
contract, agreement, license, lease, or other document to which the Borrower is
a party, which would, individually or in the aggregate, have a Material Adverse
Effect.

         Section 4.9 EMPLOYEE BENEFIT PLANS. All Benefit Plans and all
Multiemployer Plans in which the employees of the Borrower participate comply in
all material respects with all requirements of the Department of Labor and the
Internal Revenue Service promulgated under ERISA and with all other applicable
law. The Borrower does not have any employees covered by any Multiemployer Plan.
The Borrower has not taken or failed to take any action with respect to the
Benefit Plans which might create any liability on the part of the Borrower
which, individually, or in the aggregate, would have a Material Adverse Effect.
Each "fiduciary" (within the meaning of section 3(21)(A) of ERISA) as to each
Benefit Plan and, to the best of the knowledge of the Borrower, as to each
Multiemployer Plan, has complied in all material respects with the requirements
of ERISA and all other applicable law in respect of each such Plan. In addition,
as of the date hereof:

                  (i) No Defined Benefit Plan or, to the best of the knowledge
of the Borrower, any Multiemployer Plan, has incurred an "accumulated funding
deficiency" (within the meaning of section 412(a) of the Code), whether or not
waived;

                  (ii) No "reportable event" (within the meaning of section 4043
of ERISA) has occurred with respect to any Benefit Plan or, to the best of the
knowledge of the Borrower, any Multiemployer Plan; there have been no
terminations of any Defined Benefit Plan or, to the best of the knowledge of the
Borrower, any Multiemployer Plan, or any related trust; and no such termination
of any of the foregoing reasonably can be expected to occur;

                  (iii) No "prohibited transaction" (within the meaning of
section 406 of ERISA or section 4975(c) of the Code) has occurred with respect

                                      -17-
<PAGE>   22

to any Benefit Plan, or to the best of the knowledge of the Borrower, any
Multiemployer Plan;

                  (iv) The aggregate present value of accrued benefits of the
Defined Benefit Plans is not more than the aggregate value of the assets of such
plans; there has been no withdrawal liability incurred by the Borrower with
respect to any Multiemployer Plans; and the Borrower has not withdrawn
(partially or totally within the meaning of ERISA) from any Multiemployer Plan;
and

                  (v) Other than claims in the ordinary course for benefits with
respect to any Benefit Plan, or, to the best of the knowledge of the Borrower,
any Multiemployer Plan, there are no actions, suits, or claims pending with
respect to any Plan or any circumstances known to the Borrower which might give
rise to any such action, suit, or claims, which, individually, or in the
aggregate, would have a Material Adverse Effect.

         Section 4.10 DISPUTES AND LITIGATION. There is no action, suit,
proceeding, or claim, pending or, to the knowledge of the Borrower, threatened,
and no investigation by any court or government or governmental agency or
instrumentality, domestic or foreign, pending or, to the best of the knowledge
of the Borrower, threatened, against the Borrower before any court, government
or governmental agency or instrumentality, domestic or foreign, nor is there any
outstanding order, writ, judgment, stipulation, injunction, decree,
determination, award, or other order of any court or government or governmental
agency or instrumentality, domestic or foreign, against the Borrower, in each
case which would have, individually or in the aggregate, a Material Adverse
Effect. Without limiting any other representation or warranty herein, all
claims, actions, suits or proceedings pending or, to the knowledge of the
Borrower, threatened against the Borrower before any court, governmental agency
or instrumentality, domestic or foreign, are covered by, and within the limits
of coverage of, insurance maintained by the Borrower. The use by the Borrower of
its assets and the conduct of its business does not, to its knowledge, involve
infringement or claimed infringement of any patent, trademark, servicemark,
tradename, copyright, license or similar right.

         Section 4.11 COMPLIANCE WITH LAW; LICENSES; FRANCHISES; ENVIRONMENTAL
LAWS.

                  (a) The Borrower is not, and is not directly or indirectly
controlled by or acting on behalf of any party which is, an "investment company"
within the meaning of the U.S. Investment Company Act of

1940, as amended.

                  (b) The Borrower has (or has made timely application for) all
franchises, licenses, permits and other governmental and non-governmental

                                      -18-
<PAGE>   23

approvals necessary to enable it to carry on its business and operations as
currently conducted, the failure to have which would, individually or in the
aggregate, have a Material Adverse Effect. All such franchises, licenses,
permits, and governmental and other approvals are in full force and effect,
there has been no material default or breach thereunder, and there is no pending
or, to the best of the knowledge of the Borrower, threatened proceeding under
which any may be revoked, terminated or suspended. The execution and delivery of
this Agreement, and the consummation of the transactions contemplated hereby,
will not conflict with, contravene or terminate any such franchises, licenses,
permits or governmental or other approvals. The Borrower has not violated, nor
is alleged to have violated, any law, rule, regulation, judgment, stipulation,
injunction, decree, determination, award or other order of any government, or
governmental agency or instrumentality, domestic or foreign, binding upon the
Borrower which violation, individually or in aggregate, might have a Material
Adverse Effect.

                  (c) Neither the consummation of the transactions contemplated
by this Agreement nor, to the knowledge of the Borrower, any real property
utilized by the Borrower nor, to the knowledge of the Borrower, any condition
thereon violates any Environmental Laws, other than any such violations which
would not have a Material Adverse Effect, and no provisions of any Environmental
Laws or regulations in any way affect the consummation of the transactions
contemplated by this Agreement.

         Section 4.12 USE OF PROCEEDS. The Borrower shall apply the proceeds of
the Loan solely in accordance with Schedule 4.12 annexed hereto.

         Section 4.13 PRINCIPAL EXCHANGE/MARKET. The principal market on which
the Common Stock is currently traded is Nasdaq.

         Section 4.14 NO MATERIAL ADVERSE CHANGE. Since March 31, 2000, the date
through which the most recent quarterly report of the Borrower on Form 10-QSB
has been prepared and filed with the Commission, a copy of which is included in
the SEC Documents, no event which had or is likely to have a Material Adverse
Effect has occurred or exists with respect to the Borrower.

         Section 4.15 NO UNDISCLOSED LIABILITIES. The Borrower does not have any
liabilities or obligations not disclosed in the SEC Documents other than those
liabilities incurred in the ordinary course of their respective businesses since
March 31, 2000 or liabilities or obligations, individually or in the aggregate,
which do not or would not have a Material Adverse Effect on the Borrower.

         Section 4.16 NO UNDISCLOSED EVENTS OR CIRCUMSTANCES. No event or

                                      -19-
<PAGE>   24

circumstances has occurred or events with respect to the Borrower, or its
business, properties, prospects, operations or financial conditions, which,
under applicable law, rule or regulation, requires public disclosure or
announcement of the Borrower which has not been publicly announced or disclosed.

         Section 4.17 BROKERS. The Borrower has taken no action which would give
rise to any claim by any Person (other than Sanders Morris Harris) for brokerage
commissions, finder's fees or similar payments relating to this Agreement or the
transactions contemplated hereby.

         Section 4.18 PRIVATE PLACEMENT. The Borrower has heretofore given each
Lender access to all information which it has requested regarding the business
and affairs of the Borrower. Neither the Borrower nor anyone acting on its
behalf has directly or indirectly offered any shares of Common Stock or any
other securities for sale to, or solicited any offer to buy any of the same
from, anyone so as to bring the offer, sale, issuance and/or delivery of the
Notes, the Warrants or the Warrant Shares, or any of them, within the
registration requirements of the Securities Act of 1933, as amended or any
applicable state securities laws. Neither the offer, sale, issuance and/or
delivery of the Notes, the Warrant or the Warrant Shares, nor any of them, in
accordance with the terms of this Agreement will result in any contravention of
any applicable federal or state securities laws, and will not require any
approval or consent of any governmental authority, commission or agency.

         Section 4.19 DISCLOSURE. No representation or warranty made under any
provisions of the Loan Documents, or any of them, and none of the information
furnished by the Borrower set forth herein, in the exhibits or schedules hereto
or in any document specifically referenced in this Agreement and delivered to
any of the Lenders, or any authorized representative of any of the Lenders,
pursuant to this Agreement, contains any untrue statement of a material fact or
omits to state a material fact necessary to make the statements herein or
therein not misleading.

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES
                                 OF THE LENDERS

      Each of the Lenders, severally, represents, warrants and covenants to
the Borrower that:

         Section 5.1 FORMATION. Such Lender is duly organized, validly existing
and in good standing under the laws of its jurisdiction of formation, and has
full power and authority to acquire its Proportionate Share of the Loan, the
Warrants, and the Warrant Shares, and to perform its obligations under the Loan
Documents, and each of them.

                                      -20-
<PAGE>   25

         Section 5.2 AUTHORIZATION. The execution and delivery of the Loan
Documents, and each of them, by such Lender, the performance by such Lender of
its covenants and agreements under the Loan Documents, and each of them, and the
consummation by such Lender of the transactions contemplated by the Loan
Documents, and each of them, have been duly authorized by all necessary action.
When executed and delivered by such Lender, the Loan Documents, and each of
them, will constitute the valid and legally binding obligations of such Lender
enforceable against such Lender in accordance with their respective terms,
except as may be limited by bankruptcy, insolvency, or other laws affecting
generally the enforceability of creditors' rights and by limitations on the
availability of equitable remedies.

         Section 5.3 CONFLICTS. Neither the execution and delivery of the Loan
Documents, nor any of them, nor the consummation of the transactions
contemplated in the Loan Documents, nor any of them: will violate any provision
of the organizational documents of such Lender or any law, rule, regulation,
writ, judgment, injunction, decree, determination, award, or other order of any
court, government or governmental agency or instrumentality, domestic or
foreign, binding upon such Lender; or conflict with or result in any breach of
any of the terms of, or constitute a default under or result in the termination
of or the creation or imposition of any mortgage, deed of trust, pledge, lien,
security interest or other charge or encumbrance of any nature pursuant to, the
terms of any contract or agreement to which such Lender is a party or by which
such Lender or any of its assets and properties is bound, which breach, default,
termination, creation, imposition, or other charge or encumbrance would,
individually or in the aggregate, have a material adverse impact on the ability
of such Lender to consummate the transactions contemplated by the Loan
Documents.

         Section 5.4 PRIVATE PLACEMENT. (a) Without limiting the scope of the
representations and warranties of the Borrower set forth in Article IV of this
Agreement, such Lender acknowledges that, at its request, it has received
certain information from the Borrower and that it has had the opportunity to ask
representatives of the Borrower questions and receive answers in connection with
the transactions contemplated hereby, and so as to verify the accuracy of the
information so received. Each Lender acknowledges that an investment in the
Borrower involves a high degree of risk. Such Lender is an "accredited investor"
as defined under Regulation D promulgated by the Commission.

                  (b) Each Lender is acquiring the Warrants for its own account
and not with a view to distribution in violation of any securities laws. Each
Lender does not have any present intention to sell the Warrants or the Warrant

                                      -21-
<PAGE>   26

Shares and does not have any present arrangement (whether or not legally
binding) to sell the Warrants to or through any person or entity; provided,
however, that by its representations and warranties herein, each Lender does not
agree to hold the Warrants or the Warrant Shares for any minimum or other
specific term and reserves the right to dispose of the Warrants or the Warrant
Shares at any time in accordance with federal and state securities laws
applicable to such disposition.

                                   ARTICLE VI

<PAGE>   29

such happening shall be voluntary or involuntary or come about or be effected by
operation of law or pursuant to or in compliance with any judgment, decree or
order of any court or any order, rule or regulation of any administrative or

stated maturity, unless, in the case of each of (i) and (ii), such holder or
holders or trustee shall have waived such default after its occurrence or unless

                           (iii) make an assignment for the benefit of
                  creditors;

                           (iv) consent to the appointment of a receiver of
                  itself or of the whole or any substantial part of its
                  property; or

                           (v) file a petition or answer seeking reorganization
                  or arrangement under the Federal bankruptcy laws or any other
                  applicable law or statute of the United States of America or
                  any State, district or territory thereof;

                  (h) if a court of competent jurisdiction shall enter, except
at the direct or indirect request of the Lenders, an order, judgment, or decree
appointing, without the consent of the Borrower or any Subsidiary, a receiver of
the Borrower or any Subsidiary, respectively, or of the whole or any substantial
part of its property, or approving a petition filed against it seeking
reorganization or arrangement of the Borrower or any Subsidiary under the
Federal bankruptcy laws or any other applicable law or statute of the United
States of America or any State, district or territory thereof, or any other
jurisdiction, and such order, judgment or decree shall not be vacated or set
aside or stayed within 60 days from the date of entry thereof; or

                  (i) if, under the provisions of any other law for the relief
or aid of debtors, any court of competent jurisdiction shall assume custody or
control of the Borrower or any Subsidiary or of the whole or any substantial
part of its property and such custody or control shall not be terminated or
stayed within 60 days from the date of assumption of such custody or control.

         Section 7.2. ENFORCEMENT. In the case any one or more of the Events of
Default specified in Section 7.1 hereof shall have occurred and be continuing,
the Lenders, or any of them, may proceed to protect and enforce their respective

                                      -26-
<PAGE>   31

rights either by suit in equity and/or by action at law, whether for the
specific performance of any covenant or agreement contained in this Agreement,
its Note or its rights under any other Loan Document, or the Required Lenders
may proceed to enforce the payment of all Obligations or to enforce any other
legal or equitable right of the Lenders. The Borrower hereby expressly waives
presentment, demand or notice of any kind in connection with the exercise by the
Lenders, or any of them, of their respective rights hereunder, except as
explicitly provided herein. In the event an Event of Default shall have occurred
and any holder of a Note shall employ attorneys, or incur other costs and
expenses for the collection of payments due or to become due, or for the
enforcement or performance or observance of any obligation or agreement of the
Borrower, the Borrower agrees that it will pay to such holder, on demand, the
reasonable fees of such attorney together with all other costs and expenses
incurred by such holder.

         Section 7.3 WAIVER OF JURY TRIAL. THE BORROWER HEREBY WAIVES ANY AND
ALL RIGHTS THAT IT MAY NOW OR HEREAFTER HAVE UNDER THE LAWS OF THE UNITED STATES
OF AMERICA OR ANY STATE OR OTHER JURISDICTION, TO A TRIAL BY JURY OF ANY AND ALL
ISSUES ARISING EITHER DIRECTLY OR INDIRECTLY IN ANY ACTION OR PROCEEDING BETWEEN
THE BORROWER, THE LENDERS OR THEIR SUCCESSORS AND ASSIGNS, OUT OF OR IN ANY WAY
CONNECTED WITH THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS. IT IS INTENDED THAT
SAID WAIVER SHALL APPLY TO ANY AND ALL DEFENSES, RIGHTS, AND/OR COUNTERCLAIMS IN
ANY ACTION OR PROCEEDING.

                                  ARTICLE VIII

                                  REGISTRATION

         Section 8.1 REGISTRATION AND LISTING. Until the earlier of (i) such
time as the Lenders or their respective assigns no longer own Registrable
Securities or (ii) the expiration of the Effectiveness Period, the Borrower will
cause the Common Stock to continue to be registered under Section 12(g) of the
Exchange Act, will comply in all respects, with its reporting and filing
obligations under the Exchange Act, and will not take any action or file any
document (whether or not permitted by the Exchange Act or the rules thereunder)
to terminate or suspend such reporting and filing obligations. The Borrower
shall take further action as any holder of Registrable Securities may reasonably
request, all to the extent required from time to time to enable such holder to
sell Registrable Securities without registration under the Securities Act within
the limitation of the exemptions provided by (i) Rule 144 under the Securities
Act, as such rule may be amended from time to time, or (ii) any similar rule or
regulation hereafter adopted by the Commission. Upon the request of any holder
of Registrable Securities, the Borrower shall deliver to such holder a written
statement as to whether it has complied with such information and requirements.
Until the earlier of (i) such time as the Lenders or their respective assigns no
longer own Registrable Securities or (ii) the expiration of the Effectiveness
Period, the Borrower shall use its reasonable business efforts to continue the
listing or trading of the Common Stock on Nasdaq, the Nasdaq National Market or
a principal exchange and comply in all respects with the Borrower's reporting,
filing and other obligations under the bylaws or rules of Nasdaq and any
exchange or market on which shares of the Common Stock are then traded.

         Section 8.2 REGISTRATION REQUIREMENTS. The Borrower shall use its
reasonable business efforts to effect the registration of the Registrable
Securities (including without limitation the execution of an undertaking to file
post-effective amendments, appropriate qualification under applicable blue sky
or other state securities laws and appropriate compliance with applicable
regulations issued under the Securities Act) as would permit or facilitate the
resale or distribution of all the Registrable Securities in the manner
(including manner of sale) and in all states reasonably requested by the holder
thereof (each a "Holder"). Such reasonable business efforts by the Borrower
shall include the following:

                  (a) the Borrower shall, as expeditiously as reasonably
possible after the Closing Date:

                           (i) Prepare and file a registration statement with
         the Commission pursuant to Rule 415 under the Securities Act on such
         appropriate registration form of the Commission as shall be reasonably
         selected by the Borrower covering the Registrable Securities

                                      -28-
<PAGE>   33

         (hereinafter referred to as a "Registration Statement") within 45 days
         following the Closing Date. Thereafter, the Borrower shall use its
         reasonable business efforts to cause such Registration Statement to be
         declared effective by the Commission within 90 days following the
         Closing Date. In the event that such Registration Statement is not
         declared effective within 90 days following the Closing Date, there
         shall be a 30 day grace period. The Borrower shall use its reasonable
         best efforts to cause the Registration Statement to become effective
         during this 30 day grace period, if applicable. In the event that such
         Registration Statement has not been declared effective within 120 days
         from the Closing Date, then the Borrower shall, until the Registration
         Statement is declared effective, pay in cash to the Lenders, and each
         of them, an amount equal to 2% of the Loan then outstanding
         (hereinafter referred to as the "Liquidated Damages") advanced by such
         Lender for each 30 day period, or part thereof, beginning on the 121st
         day following the Closing Date (hereinafter referred to as the "Default
         Period") that the Registration Statement has not been declared
         effective; provided, however, that the Default Period shall terminate
         and Liquidated Damages shall cease to accrue on the date upon which all
         such Registrable Securities may be immediately sold under Rule 144 in
         the reasonable opinion of counsel to the Borrower (provided that the
         Borrower's transfer agent has accepted an instruction from the Borrower
         to such effect). If any applicable Default Period is less than 30 days
         such cash payment shall be on a pro rata basis. Such cash payment shall
         be calculated by the Borrower on the earlier of (i) the effective date
         of such Registration Statement or (ii) the last day of each Default
         Period, and a check in lawful money of the United States of America
         shall be sent within three business days of such calculation to each of
         the Lenders. Following the initial effective date of such Registration
         Statement, Liquidated Damages shall also be payable to each of the
         Lenders by the Borrower for periods (in excess of the time period in
         which the Borrower is required to file a Current Report on Form 8-K)
         during which the Registration Statement does not remain effective;
         provided, however, that such Liquidated Damages shall not be payable by
         the Borrower in the event that all such Registrable Securities may be
         immediately sold by the Lenders pursuant to Rule 144. Notwithstanding

                                      -29-
<PAGE>   34

         the foregoing, if the Default Period commences from the failure of the
         Borrower to cause to become effective the Registration Statement solely
         by reason of the failure of any Lender to provide such information as
         (i) the Borrower may reasonably request from such Lender to be included
         in the Registration Statement or (ii) the Commission or Nasdaq may
         request in connection with such Registration Statement, the Borrower
         shall not be required to pay such Liquidated Damages to such Lender
         during the period of delay attributable to such Lender's failure. The
         Borrower and the Lenders hereby acknowledge and agree that it may be
         difficult, if not impossible, to determine with any reasonable accuracy
         the actual damages arising from the failure to secure effectiveness of
         the Registration Statement by the time hereinbefore specified, or to
         maintain the Registration Statement thereafter, and that the amount of
         the Liquidated Damages is a reasonable estimate thereof, provided that
         payment thereof shall in no manner be construed as impairing the right
         of the Lenders, and each of them, to require specific performance of
         this Agreement.

                           (ii) Prepare and file with the Commission such
         amendments and supplements to such Registration Statement and the
         prospectus used in connection with such Registration Statement as may
         be necessary to comply with the provisions of the Securities Act with
         respect to the disposition of all securities covered by such
         Registration Statement and notify each of the Lenders of the filing and
         effectiveness of such Registration Statement and any amendments or
         supplements.

                           (iii) Furnish to each of the Lenders such number of
         copies of a current prospectus conforming with the requirements of the
         Securities Act, copies of the Registration Statement, any amendment or
         supplement thereto and any documents incorporated by reference therein
         and such other documents as each of the Lenders may reasonably require
         in order to facilitate the disposition of Registrable Securities owned
         by each of the Lenders.

                           (iv) Use its best efforts to register and qualify the
         securities covered by such Registration Statement under such other
         securities or "Blue Sky" laws of such jurisdictions as shall be
         reasonably requested by each of the Lenders; provided that the Borrower
         shall not be required in connection therewith or as a condition thereto
         to qualify to do business or to file a general consent to service of
         process in any such states or jurisdictions.

                           (v) Notify each of the Lenders immediately of the
         happening of any event as a result of which the prospectus (including
         any supplement thereto or thereof) included in such Registration
         Statement, as then in effect, includes an untrue statement of material
         fact or omits to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading in light of the
         circumstances then existing, and use its best efforts to promptly
         update and/or correct such prospectus.

                           (vi) Notify each of the Lenders immediately of the
         issuance by the Commission or any state securities commission or agency
         of any stop order suspending the effectiveness of the Registration

                                      -30-
<PAGE>   35

         Statement or the initiation of any proceedings for that purpose. The
         Borrower shall use its reasonable best efforts to prevent the issuance
         of any stop order and, if any stop order is issued, to obtain the
         lifting thereof at the earliest possible time.

                           (vii) Permit a single firm of counsel, designated by
         the Lenders, to review the Registration Statement and all amendments
         and supplements thereto within a reasonable period of time prior to
         each filing, and shall not file any document in a form to which such
         counsel reasonably objects.

                           (viii) Use its reasonable business efforts to list
         the Registrable Securities covered by such Registration Statement with
         all securities exchange(s) and/or markets on which the Common Stock is
         then listed, and prepare and file any required filings with the
         National Association of Securities Dealers, Inc. or any exchange or
         market where the Common Stock is traded.

                           (ix) Otherwise use its reasonable business efforts to
         comply with all applicable rules and regulations of the Commission and
         make available to its security holders, as soon as reasonably
         practicable, earnings statements covering a period of twelve months
         beginning with three months after the effective date of the
         Registration Statement, which earnings statement shall satisfy the
         provisions of Section 11(a) of the Securities Act.

                  (b) The Borrower shall make available for inspection by the
Lenders and their representative(s), any underwriter participating in any
disposition pursuant to a Registration Statement, and any attorney or accountant
retained by the Lenders or underwriter, all financial and other records
customary for purposes of the Lender's due diligence examination of the Borrower
and all SEC Documents filed subsequent to the Closing Date, pertinent corporate
documents and properties of the Borrower, and cause the Borrower's officers,
directors and employees to supply all information reasonably requested by any
such representative, underwriter, attorney or accountant in connection with such
Registration Statement, provided that such parties agree to keep such
information confidential.

         Section 8.3 EXPENSES OF REGISTRATION. All Registration Expenses
incurred in connection with any registration, qualification or compliance with
registration pursuant to this Article VIII shall be borne by the Borrower, and
all Selling Expenses of any Lender shall be borne by such Lender.

         Section 8.4 REGISTRATION PERIOD. In the case of the registration
effected by the Borrower pursuant to this Article VIII, the Borrower will use
its reasonable business efforts to keep such registration effective (hereinafter

                                      -31-
<PAGE>   36

referred to as the "Effectiveness Period") until the earliest to occur of (a)
two years from the date of exercise of the last Warrant to be exercised prior to
the expiration thereof, provided that, without limiting any provision of Section
8.2(a)(i), the Borrower may suspend the effectiveness of the Registration
Statement if its Board of Directors determines, upon advice of counsel, that in
order to maintain effectiveness of the Registration Statement, the Borrower
would be required to disclose a significant corporate development which
disclosure would have a material effect on the Borrower; PROVIDED, HOWEVER, that
the period of time which such Registration Statement is required to be effective
shall be increased by the number of days that the Registration Statement's
effectiveness was suspended, if any, (b) the date on which the Lenders have
completed the sale or distribution described in the Registration Statement
relating thereto, or (c) the date on which such Registrable Securities may be
sold under Rule 144(k) in the reasonable opinion of counsel to the Borrower
(provided that the Borrower's transfer agent has accepted an instruction from
the Borrower to such effect).

         Section 8.5 INDEMNIFICATION. (a) The Borrower will indemnify each
holder of Registrable Securities, each of its officers, directors and partners,
and each person controlling such holder of Registrable Securities, within the
meaning of Section 15 of the Securities Act and the rules and regulations
thereunder with respect to which registration, qualification or compliance has
been effected pursuant to this Agreement, and each underwriter, if any, and each
person who controls, within the meaning of Section 15 of the Securities Act and
the rules and regulations thereunder, any underwriter, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any prospectus, offering circular or other document (including
any related registration statement, notification or the like) incident to any
such registration, qualification or compliance, or based on any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or any violation by
the Borrower of the Securities Act or any state securities law or in either
case, any rule or regulation thereunder applicable to the Borrower and relating
to action or inaction required of the Borrower in connection with any such
registration, qualification or compliance, and will reimburse each holder of
Registrable Securities, each of its officers, directors and partners, and each
person controlling such holder of Registrable Securities, each such underwriter

                                      -32-
<PAGE>   37

and each person who controls any such underwriter, for any legal and any other
expenses reasonably incurred in connection with investigating and defending any
such claim, loss, damage, liability or action, provided that the Borrower will
not be liable in any such case to a holder of Registrable Securities to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission based upon written information
relating to such holder or underwriter and furnished to the Borrower by such
holder or the underwriter (if any) therefor and stated to be specifically for
use therein. The indemnity agreement contained in this Section 8.5(a)shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability
or action if such settlement is effected without the consent of the
Borrower(which consent will not be unreasonably withheld).

                  (b) Each holder of Registrable Securities will, severally and
not jointly, if Registrable Securities held by it are included in the securities
as to which such registration, qualification or compliance is being effected,
indemnify the Borrower, each of its directors, officers, partners, and each
underwriter, if any, of the Borrower's securities covered by such a registration
statement, each person who controls the Borrower or such underwriter within the
meaning of Section 15 of the Securities Act and the rules and regulations
thereunder, each other holder of Registrable Securities (if any), and each of
their directors, officers and partners, and each person controlling such other
holder(s) of Registrable Securities against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement, prospectus, offering circular or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statement therein not
misleading, in each case only insofar as such untrue statement or alleged untrue
statement or omission relates to such holder of Registrable Securities, and will
reimburse the Borrower and such other holder(s) of Registrable Securities and
their directors, officers and partners, underwriters or control persons for any
legal or any other expenses reasonably incurred in connection with investigating
and defending any such claim, loss, damage, liability or action, in each case to
the extent, but only to the extent, that such untrue statement (or alleged
untrue statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular or other document in reliance upon and
in conformity with written information furnished to the Borrower by such holder
of Registrable Securities and stated to be specifically for use therein, and
provided that the maximum amount for which such holder of Registrable Securities
shall be liable under this indemnity shall not exceed the net proceeds received
by such holder of Registrable Securities from the sale of the Registrable
Securities. The indemnity agreement contained in this Section 8.5(b) shall not
apply to amounts paid in settlement of any such claims, losses, damages or
liabilities if such settlement is effected without the consent of such holder of
Registrable Securities (which consent shall not be unreasonably withheld).

                                      -33-
<PAGE>   38

                  (c) Each party entitled to indemnification under this Article
(hereinafter referred to as the "Indemnified Party") shall give notice to the
party required to provide indemnification (hereinafter referred to as the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge
of any claim as to which indemnity may be sought, and shall permit the
Indemnifying Party to assume the defense of any such claim in any litigation
resulting therefrom, provided that counsel for the Indemnifying Party, who shall
conduct the defense of such claim or any litigation resulting therefrom, shall
be approved by the Indemnified Party (whose approval shall not be unreasonably
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Article VIII except to the extent that the
Indemnifying Party is materially and adversely affected by such failure to
provide notice. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation. Each Indemnified Party shall furnish such information regarding
itself or the claim in question as an Indemnifying Party may reasonably request
in writing and as shall be reasonably required in connection with the defense of
such claim and litigation resulting therefrom.

         Section 8.6 CONTRIBUTION. If the indemnification provided for in this
Article VIII herein is unavailable to the Indemnified Parties in respect of any
losses, claims, damages or liabilities referred to herein (other than by reason
of the exceptions provided therein), then each such Indemnifying Party, in lieu
of indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such losses, claims, damages or
liabilities as between the Borrower on the one hand and any holder of
Registrable Securities on the other, in such proportion as is appropriate to
reflect the relative fault of the Borrower and of such holder of Registrable
Securities in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Borrower on the one hand and of any
holder of Registrable Securities on the other shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Borrower or by such holder.

         In no event shall the obligation of any Indemnifying Party to
contribute under this Section 8.6 exceed the amount that such Indemnifying Party
would have been obligated to pay by way of indemnification if the

                                      -34-
<PAGE>   39

indemnification provided for under Section 8.5(a) or 8.5(b) hereof had been
available under the circumstances.

         The Borrower and the Lenders agree that it would not be just and
equitable if contribution pursuant to this Section 8.6 were determined by pro
rata allocation (even if the holders or the underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in the immediately
preceding paragraphs. The amount paid or payable by an Indemnified Party as a
result of the losses, claims, damages and liabilities referred to in the
immediately preceding paragraphs shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such Indemnified Party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this section, no holder of
Registrable Securities or underwriter shall be required to contribute any amount
in excess of the amount by which (i) in the case of any holder, the net proceeds
received by such holder from the sale of Registrable Securities or (ii) in the
case of an underwriter, the total price at which the Registrable Securities
purchased by it and distributed to the public were offered to the public
exceeds, in any such case, the amount of any damages that such holder or
underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement, omission or alleged omission. 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.

                                   ARTICLE IX

                                  MISCELLANEOUS

         Section 9.1 MODIFICATION OF AGREEMENT. No modification, amendment or
waiver of any provision of, nor any consent required by, this Agreement, nor any
consent to any departure by the Borrower therefrom, shall in any event be
effective unless the same shall be in writing and signed by the Required Lenders
and then such modification, amendment, waiver or consent shall be effective only
in the specific instance and for the purpose which given; provided, however,
that, without the written consent of the affected Lender, no such action shall:
reduce the amount of principal or required principal payments due to such
Lender; reduce the rate of interest payable to such Lender; postpone any date
fixed for payment of principal or interest to such Lender; or amend the
definition of "Required Lenders". No notice to or demand on the Borrower in any
case shall entitle the Borrower to any other or further notice or demand in the
same, similar or other circumstances.

         Section 9.2 REMEDIES CUMULATIVE, ETC. No right, power or remedy herein
conferred upon or reserved to the Lenders is intended to be exclusive of any
other right, power or remedy or remedies, and each and every right, power and

                                      -35-
<PAGE>   40

remedy of the Lenders, or any of them, pursuant to this Agreement, or the other
Loan Documents, now or hereafter existing at law or in equity or by statute or
otherwise shall, to the extent permitted by law, be cumulative and concurrent
and shall be in addition to every other right, power or remedy pursuant to this
Agreement, or the other Loan Documents, or now or hereafter existing at law or
in equity or by statute or otherwise, and the exercise or beginning of the
exercise by the Lenders, or any of them, of any one or more of such rights,
