                      LITIGATION AND CONTINGENT LIABILITIES

On April 19, 2000, World Fuel Services ("WFS") filed a Demand for Arbitration
against EarthCare, which requests damages in the approximate amount of $3.7
million plus interest, late fees, court costs and attorneys fees, alleging
breach of contract. Pursuant to the terms of Stock Purchase Agreement between
WFS and EarthCare dated as of January 12, 2000, the parties have agreed to
arbitrate in Miami-Dade County, Florida. EarthCare plans to zealously present
its positions and does not believe, at this point, that a decision, even if
favorable to WFS will have a material adverse effect on EarthCare's business or
operations.

       Stock Purchase Agreement between WFS and EarthCare dated as of January
       12, 2000, the parties have agreed to arbitrate in Miami-Dade County,
       Florida. EarthCare plans to zealously present its positions and does not
       believe, at this point, that a decision, even if favorable to WFS will
       have a material adverse effect on EarthCare's business or operations.

2.     Facility located at 25 NE 5th Street, Pompano Beach, Florida. This
       property is leased by EarthCare Company of Florida ("EarthCare FL"). An
       underground storage tank currently or at one time existed on property
       adjacent to this facility. A monitoring well has been placed on the
       property leased by EarthCare FL. No current knowledge of any problems
       associated with this property.

3.     Facility located at 1804 Nashville Avenue, Orlando, Florida. EarthCare FL

                               ADDITIONAL GUARANTY

       THIS GUARANTY dated as of October 31, 2000 is executed in favor of BANK
OF AMERICA, N.A., as Agent, and the Lender Parties referred to below.

                                   WITNESSETH:

       WHEREAS, EARTHCARE COMPANY (the "Company") has entered into an Amended
and Restated Credit Agreement dated as of February 15, 2000 (as amended or
otherwise modified from time to time, the "Credit Agreement"; terms used but not
defined herein are used as defined in the Credit Agreement) with various
financial institutions and BANK OF AMERICA, N.A., as agent (in its capacity as
agent, together with any successor in such capacity, the "Agent"), pursuant to
which such financial institutions have agreed to make loans to, and issue or
participate in letters of credit for the account of, the Company;

       WHEREAS, the Agent, the Required Banks and the Company have entered into
a Second Amendment to the Credit Agreement dated as of the date hereof (the
"Second Amendment");

       WHEREAS, the undersigned is a significant investor in the Company, and
has previously executed a Guaranty dated as of February 15, 2000 (the "Existing
Guaranty") in favor of the Agent to guaranty the Liabilities (as defined below);
and

       WHEREAS, in consideration of the amendments, waivers and consents set
forth in the Second Amendment, the undersigned, subject to the terms hereof, is
willing to further guaranty the Liabilities as hereinafter set forth;

       NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the undersigned hereby
unconditionally and irrevocably, as primary obligor and not merely as surety,
guarantees the full and prompt payment when due, whether by acceleration or
otherwise, and at all times thereafter, of all obligations of the Company to
each of the Agent and each Lender Party (as defined below) under or in
connection with the Credit Agreement, the Notes, any other Loan Document, any
Hedging Contract entered into with any Lender Party and any other instrument or
document executed in connection with any of the foregoing, in each case
howsoever created, arising or evidenced, whether direct or indirect, absolute or
contingent, now or hereafter existing, or due or to become due (all such
obligations being herein collectively called the "Liabilities"); provided,
however, that the liability of the undersigned hereunder shall be limited to the
Maximum Principal Liability Amount (as defined below) plus interest accruing on
such amount (or such lesser amount of the Liabilities as is outstanding) after
demand by the Agent hereunder (including interest at the rate specified in any
applicable agreement accruing after any bankruptcy or insolvency proceeding with
respect to the Company regardless of whether such interest is an allowed claim
in such proceeding) plus all costs and expenses paid or incurred by the Agent or
any Lender Party in enforcing this Guaranty against the undersigned). As used
herein, (i) "Lender Party" means each Bank under and as defined in the Credit
Agreement and any Affiliate of such a Bank which is a

<PAGE>   19

party to a Hedging Contract with the Company; and (ii) Maximum Principal
Liability Amount means $20,000,000; provided that if the Company has not
completed a sale of the EarthLiquids Subsidiaries on or before December 31,
2000, the Maximum Principal Liability Amount shall be automatically increased to
an amount equal to the remainder of $40,000,000 minus the amount of all Asset
Sale Commitment Reductions made during the period from September 30, 2000
through December 31, 2000; and provided, further, that if the Maximum Principal
Liability Amount is increased on December 31, 2000, then the Maximum Principal
Liability Amount shall be decreased (but not below $20,000,000) by the amount of
all Asset Sale Commitment Reductions made after December 31, 2000. For purposes
of the foregoing, "Asset Sale Commitment Reduction" means any reduction in the
Commitments made pursuant to Section 6.1.3(b) of the Credit Agreement at a time
when no Event of Default or Unmatured Event of Default exists or will result
from such reduction or the sale of assets giving rise thereto.

       The undersigned acknowledges that the obligations of the undersigned
under this Guaranty are in addition to the obligations of the undersigned under
the Existing Guaranty and that the Agent and the Lender Parties may make demand
under this Guaranty, and enforce their rights and remedies under this Guaranty,
and enforce their rights and remedies under this Guaranty, before, after or
concurrently with making demand and/or enforcing rights and remedies under the
Existing Guaranty.

       The undersigned agrees that, in the event of the dissolution or
insolvency of the Company, or the insolvency, death or legal incapacity of the
undersigned, or the inability or failure of the Company or the undersigned to
pay debts as they become due, or an assignment by the Company or the undersigned
for the benefit of creditors, or the occurrence of any other Event of Default
under Section 12.1.4 of the Credit Agreement, and if such event shall occur at a
time when any of the Liabilities may not then be due and payable, the
undersigned will pay to the Agent for the account of the Lender Parties
forthwith the full amount which would be payable hereunder by the undersigned if
all Liabilities were then due and payable.

       This Guaranty shall in all respects be a continuing, irrevocable,
absolute and unconditional guaranty, and (except as expressly provided below)
shall remain in full force and effect (notwithstanding, without limitation, that
at any time or from time to time no Liabilities are outstanding) until all
Commitments have terminated and all Liabilities have been paid in full.

       The undersigned agrees that if at any time all or any part of any payment
theretofore applied by the Agent or any Lender Party to any of the Liabilities
is or must be rescinded or returned by the Agent or such Lender Party for any
reason whatsoever (including the insolvency, bankruptcy or reorganization of the
Company or the undersigned), such Liabilities shall, for the purposes of this
Guaranty, to the extent that such payment is or must be rescinded or returned,
be deemed to have continued in existence, notwithstanding such application by
the Agent or such Lender Party, and this Guaranty shall continue to be effective
or be reinstated, as the case may be, as to such Liabilities, all as though such
application by the Agent or such Lender Party had not been made.

       The Agent or any Lender Party may, from time to time, at its sole
discretion and without notice to the undersigned, take any or all of the
following actions: (a) retain or obtain a security

<PAGE>   20

interest in any property to secure any of the Liabilities or any obligation
hereunder, (b) retain or obtain the primary or secondary obligation of any
obligor or obligors, in addition to the undersigned, with respect to any of the
Liabilities, (c) extend or renew any of the Liabilities for one or more periods
(whether or not longer than the original period), alter or exchange any of the
Liabilities, or release or compromise any obligation of the undersigned
hereunder or any obligation of any nature of any other obligor with respect to
any of the Liabilities, (d) release its security interest in, or surrender,
release or permit any substitution or exchange for, all or any part of any
property securing any of the Liabilities or any obligation hereunder, or extend
or renew for one or more periods (whether or not longer than the original
period) or release, compromise, alter or exchange any obligations of any nature
of any obligor with respect to any such property, and (e) resort to the
undersigned for payment of any of the Liabilities when due, whether or not the
Agent or such Lender Party shall have resorted to any property securing any of
the Liabilities or any obligation hereunder or shall have proceeded against any
other obligor primarily or secondarily obligated with respect to any of the
Liabilities.

       The undersigned agrees to deliver to the Agent cash collateral, or other
collateral reasonably satisfactory to the Agent, in an amount (with the value of
any non-cash collateral being determined by the Agent in its discretion) not
less than $5,000,000 on or before October 31, 2000 and an additional $10,000,000
on or before November 30, 2000. Such collateral shall be held by the Agent as
security for the obligations of the undersigned hereunder pursuant to
documentation reasonably satisfactory to the Agent. Upon any demand by the Agent
hereunder, the Agent may immediately apply such collateral (or the proceeds
thereof in the case of non-cash collateral) to the payment of the Liabilities.
The undersigned acknowledges that the obligation to provide collateral set forth
in this paragraph is in addition to any obligation of the undersigned to provide
collateral pursuant to the Existing Guaranty.

       The undersigned hereby expressly waives: (a) notice of the acceptance by
the Agent or any Lender Party of this Guaranty, (b) notice of the existence or
creation or non-payment of all or any of the Liabilities, (c) presentment,
demand, notice of dishonor, protest, and all other notices whatsoever, and (d)
all diligence in collection or protection of or realization upon any Liabilities
or any security for or guaranty of any Liabilities.

       Notwithstanding any payment made by or for the account of the undersigned
pursuant to this Guaranty, the undersigned shall not be subrogated to any right
of the Agent or any Lender Party until such time as the Agent and the Lender
Parties shall have received final payment in cash of the full amount of all
Liabilities.

       The undersigned further agrees to pay all expenses (including the
reasonable attorneys' fees and charges) paid or incurred by the Agent or any
Lender Party in endeavoring to collect the Liabilities of the undersigned, or
any part thereof, and in enforcing this Guaranty against the undersigned.

       The creation or existence from time to time of additional Liabilities to
the Agent or the Lender Parties or any of them is hereby authorized, without
notice to the undersigned, and shall in no way affect or impair the rights of
the Agent or the Lender Parties or the obligations of the undersigned under this
Guaranty.

<PAGE>   21

       The Agent and any Lender Party may from time to time without notice to
the undersigned, assign or transfer any or all of the Liabilities or any
interest therein; and, notwithstanding any such assignment or transfer or any
subsequent assignment or transfer thereof, such Liabilities shall be and remain
Liabilities for the purposes of this Guaranty, and each and every immediate and
successive assignee or transferee of any of the Liabilities or of any interest
therein shall, to the extent of the interest of such assignee or transferee in
the Liabilities, be entitled to the benefits of this Guaranty to the same extent
as if such assignee or transferee were an original Lender Party.

       No delay on the part of the Agent or any Lender Party in the exercise of
any right or remedy shall operate as a waiver thereof, and no single or partial
exercise by the Agent or any Lender Party of any right or remedy shall preclude
other or further exercise thereof or the exercise of any other right or remedy;
nor shall any modification or waiver of any provision of this Guaranty be
binding upon the Agent or the Lender Parties, except as expressly set forth in a
writing duly signed and delivered on behalf of the Agent. No action of the Agent
or any Lender Party permitted hereunder shall in any way affect or impair the
rights of the Agent or any Lender Party or the obligations of the undersigned
under this Guaranty. For purposes of this Guaranty, Liabilities shall include
all obligations of the Company to the Agent or any Lender Party arising under or
in connection with the Credit Agreement, any Note, any other Loan Document, any
Swap Contract or any other document or instrument executed in connection with
any of the foregoing, notwithstanding any right or power of the Company or
anyone else to assert any claim or defense as to the invalidity or
unenforceability of any such obligation, and no such claim or defense shall
affect or impair the obligations of any of the undersigned hereunder.

       Pursuant to the Credit Agreement, (a) this Guaranty has been delivered to
the Agent and (b) the Agent has been authorized to enforce this Guaranty on
behalf of itself and the Lender Parties. All payments by the undersigned
pursuant to this Guaranty shall be made to the Agent for the benefit of the
Lender Parties.

       This Guaranty shall be binding upon the undersigned and the heirs and
legal representatives of the undersigned. All references herein to the Company
shall be deemed to include any successor or successors, whether immediate or
remote, to such corporation.

       This Guaranty shall be governed by and construed in accordance with the
laws of the State of Illinois applicable to contracts made and to be fully
performed in such State. Wherever possible, each provision of this Guaranty
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Guaranty shall be prohibited by or
invalid under such law, such provision shall be ineffective to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Guaranty.

        This Guaranty may be executed in any number of counterparts and by the
different parties hereto on separate counterparts, and each such counterpart
shall be deemed to be an original but all such counterparts shall together
constitute one and the same Guaranty.

<PAGE>   22

       This Guaranty may be secured by one or more security agreements, pledge
agreements or other similar documents.

       ANY LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER OR IN CONNECTION
WITH THIS GUARANTY OR ANY OTHER LOAN DOCUMENT, SHALL BE BROUGHT AND MAINTAINED
EXCLUSIVELY IN THE COURTS OF THE STATE OF ILLINOIS OR IN THE UNITED STATES
DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS; PROVIDED, THAT ANY SUIT
SEEKING ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT
THE AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR
OTHER PROPERTY MAY BE FOUND. THE UNDERSIGNED HEREBY EXPRESSLY AND IRREVOCABLY
SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF ILLINOIS AND OF THE
UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS FOR THE
PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. THE UNDERSIGNED FURTHER
IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE
PREPAID, TO THE ADDRESS SET FORTH OPPOSITE HIS SIGNATURE HERETO (OR SUCH OTHER
ADDRESS AS THE UNDERSIGNED SHALL HAVE SPECIFIED IN WRITING TO THE AGENT AS HIS
ADDRESS FOR NOTICES HEREUNDER) OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE
STATE OF ILLINOIS. THE UNDERSIGNED HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH HE MAY NOW OR HEREAFTER
HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT
REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN
INCONVENIENT FORUM.

       THE UNDERSIGNED, AND (BY ACCEPTING THE BENEFITS HEREOF) EACH OF THE AGENT
AND EACH LENDER PARTY, HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION
OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS GUARANTY, ANY OTHER
LOAN DOCUMENT AND ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR
WHICH MAY IN THE FUTURE BE DELIVERED IN CONNECTION HEREWITH OR THEREWITH OR
ARISING FROM ANY BANKING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE
FOREGOING, AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A

                      THIRD AMENDMENT, WAIVER AND CONSENT

        THIS THIRD AMENDMENT, WAIVER AND CONSENT dated as of April 16, 2001
(this "Amendment") amends the Amended and Restated Credit Agreement dated as of
February 15, 2000 (as previously amended, the "Credit Agreement") among
EarthCare Company (the "Company"), various financial institutions (the "Banks")
and Bank of America, N.A., as Administrative Agent (in such capacity, the
"Administrative Agent"). Terms defined in the Credit Agreement are, unless
otherwise defined herein or the context otherwise requires, used herein as
defined therein.

        WHEREAS, the Company, the Banks and the Administrative Agent have
entered into the Credit Agreement; and

        WHEREAS, the parties hereto desire to amend the Credit Agreement in
certain respects as more fully set forth herein;

        NOW, THEREFORE, the parties hereto agree as follows:

        SECTION 1 Amendments. Subject to the satisfaction of the conditions
precedent set forth in Section 4, the Credit Agreement shall be amended as
follows:

        1.1     Addition of Definition. The following definition is added to
Section 1.1 in appropriate alphabetical order:

                EarthAmerica Subsidiaries means, collectively, the Subsidiaries
        listed under the heading "EarthAmerica Subsidiaries" on Schedule 9.8.

        1.2     Amendment to Definition of "Floating Rate Margin". The
definition of "Floating Rate Margin" is amended in its entirety to read as
follows:

        below) for any period beginning on January 1, 2001 and ending on the
        last day of any month thereafter to be less than the sum of (i) product
        of $500,000 multiplied by the number of months (or, with respect to the
        month in which the sale of the EarthAmerica Subsidiaries occurs, a
        fraction, the numerator of which is the number of days in such month
        prior to the date of sale and the denominator of which is the number of
        days in such month) elapsed between January 1, 2001 (i.e., $500,000 as
        of January 31, 2001, $1,000,000 as of February 28, 2001, etc.)

<PAGE>   2

        consummated plus (ii) the product of $375,000 multiplied by the number
        of months (or, with respect to the month in which the sale of the
        EarthAmerica Subsidiaries occurs, a fraction, the numerator of which is
        the number of days in such month from the date of such sale and the
        denominator of which is the number of days in such month) elapsed since
        the date on which the sale of the EarthAmerica Subsidiaries has been
        consummated. For purposes of the foregoing, "Adjusted EBITDA" means
        EBITDA calculated (i) without including any financial results from ERMFI
        and (ii) with the addition of the first $2,800,000 of non-cash charges,
        to the extent taken in the applicable period, related to the writeoff of
        the Company's investment in Crossroads Environmental.

        1.4     Addition of Section 12.1.12. The following new Section 12.1.12

        fees and expenses) of at least $31,000,000 within 45 days following the
        effectiveness of the Third Amendment to this Agreement, provided that no
        Event of Default shall be deemed to have occurred for failure of the
        Company to comply with this subsection (a) if the Company has engaged a
        strategic advisor acceptable to the Required Banks within 45 days
        following the effectiveness of the Third Amendment to this Agreement to
        facilitate the sale of the EarthLiquids Subsidiaries; and (b) the sale
        of the EarthAmerica Subsidiaries for cash consideration of at least
        $24,000,000 by April 30, 2001.

        1.5     Amendment to Schedule 9.8. Schedule 9.8 is amended in its
entirety to read as set forth as Schedule 9.8 hereto.

        SECTION 2  Waivers; Consents. (a) Subject to the satisfaction of the
conditions precedent set forth in Section 4, the Required Banks hereby waive:

                (i)     the Company's non-compliance with Section 10.6.7 of the

                               TO THIRD AMENDMENT

                                FORM OF WARRANT

THE SECURITY REPRESENTED BY THIS CERTIFICATE (THE "WARRANT") HAS NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
OR ANY STATE SECURITIES LAWS AND IS TRANSFERRABLE PURSUANT TO THE TERMS OF THIS
WARRANT.

                             STOCK PURCHASE WARRANT

Date of Issuance: April 16, 2001                             Certificate No. __

        For value received, EarthCare Company (the "Company") hereby grants to
_____________ or any of its permitted transferees as provided in Section 2 (the
"Registered Holder") the right to purchase from the Company 75,000 shares of the
Company's common stock, par value $0.01 per share (the "Common Stock"), at a
price per share equal to $3.60 (such price as adjusted and readjusted from time
to time in accordance with Section 3, the "Exercise Price"). The amount and kind
of securities purchasable pursuant to the rights granted hereunder and the
purchase price for such securities are subject to adjustment pursuant to the
provisions contained in this Warrant. Certain capitalized terms used herein are
defined in Section 4.

        This Warrant is subject to the following provisions:

        Section 1.      Exercise of Warrant.

        (a)     Exercise Period. The Registered Holder may exercise, in whole
or in part, the purchase rights represented by this Warrant at any time and from
time to time during the period commencing on the date hereof and ending on April
16, 2006. If the Warrant remains unexercised, in whole or in part, on April 16,
2006, the Warrant or such unexercised part thereof shall terminate.

        (b)     Exercise Procedure.

                (i)     This Warrant shall be exercised, to the extent of the
        number of shares of Common Stock described in clause (D) below, when the
        Company has received all of the following items (the "Exercise Time"):

                        (A)     the original executed copy of this Warrant;

                        (B)     a completed Exercise Agreement, in the form of
                Exhibit A, which shall be dated the actual date of execution
                thereof;

<PAGE>   11

                        (C)     if the Registered Holder is not _____________,
                an Assignment in the form of Exhibit B, evidencing the
                assignment of this Warrant; and

                        (D)     subject to clause (ii) below, a cashier's check
                payable to the Company or a wire transfer of immediately
                available funds to an account specified by the Company in an
                amount equal to the product of the Exercise Price multiplied by
                the number of shares of Common Stock being purchased upon such
                exercise.

                (ii)    Notwithstanding Section 1(b)(i)(D) above, at the
        election of the Registered Holder, which election shall be set forth in
        the Exercise Agreement, the number of shares of Common Stock being
        purchased upon exercise of the Warrant shall be equal to the quotient
        obtained by dividing (a) the product of (x) the Market Price at such
        Exercise Time less the Exercise Price, multiplied by (y) the number of
        shares of Common Stock as to which the Registered Holder elects to be
        issued under this clause (ii) (which election shall reduce the number of
        shares of Common Stock available for any subsequent exercise), by (b)
        the Market Price at such Exercise Time. The number of shares issued
        pursuant to this clause (ii) shall be excluded from the calculation of
        the amount paid pursuant to Section 1(b)(i)(D) above.

                (iii)   Certificates for shares of Common Stock purchased upon
        exercise of this Warrant shall be delivered by the Company to the
        Registered Holder within five business days after the date of the
        Exercise Time.

                (iv)    The Common Stock issuable upon exercise of this Warrant
        shall be deemed to have been issued to the Registered Holder at the
        Exercise Time, and the Registered Holder shall be the record holder of
        such Common Stock at the Exercise Time.

                (v)     If this Warrant is exercised in part, the Company
        shall, at the time of delivery of the certificate or certificates for
        Common Stock, unless this Warrant has then expired, issue and deliver
        to the Registered Holder a new Warrant evidencing the rights of the
        Registered Holder to purchase the aggregate number of shares of Common
        Stock for which this Warrant shall not have been exercised, and this
        Warrant shall be cancelled.

                (vi)    The issuance of certificates for shares of Common Stock
        upon exercise of this Warrant shall be made without charge to the
        Registered Holder for costs incurred by the Company in connection with
        such exercise and the related issuance of shares of Common Stock, except
        the Registered Holder shall pay any issuance taxes in respect thereof.

                (vii)   The Company shall not close its books against the
        transfer of this Warrant or of any shares of Common Stock issued or
        issuable upon exercise of this Warrant in any manner that interferes
        with the timely exercise of this Warrant. The Company shall

<PAGE>   12

        from time to time take all such action as may be necessary to assure
        that the par value per share of the unissued Common Stock issuable upon
        exercise of this Warrant is at all times equal to or less than the
        Exercise Price then in effect.

                (viii)  The Company shall at all times reserve and keep
        available out of its authorized but unissued shares of Common Stock
        solely for the purpose of issuance upon exercise of this Warrant, such
        number of shares of Common Stock as are then issuable upon exercise of
        this Warrant. All shares of Common Stock which are so issuable shall,
        when issued, be duly and validly issued, and upon payment of the
        Exercise Price therefor, shall be fully paid and nonassessable and free
        from all taxes, liens and charges. The Company shall take all such
        actions as may be necessary to assure that all such shares of Common
        Stock may be so issued without violation of any applicable law or
        governmental regulation or any requirements of any domestic securities
        exchange upon which shares of Common Stock are listed (except for
        official notice of issuance, which shall be immediately delivered by the
        Company upon each such issuance).

                (ix)    Upon any exercise of this Warrant, the Company may
        require customary representations from the Registered Holder to assure
        that the issuance of the Common Stock hereunder shall not require
        registration or qualification under the Securities Act or any state
        securities laws.

        Section 2.      Restrictions on Transfer. The Registered Holder shall
not sell, transfer, assign, pledge or otherwise dispose of ("Transfer") any
interest in this Warrant unless all of the following conditions are satisfied:

                (a)     such Registered Holder and the transferee shall deliver
        to the Company written notice of the Transfer five business days prior
        to the Transfer and shall execute an Assignment substantially in the
        form set forth in Exhibit B, a copy of which shall be delivered to the
        Company within 30 days after the date of execution of such Assignment;
        and

                (b)     such Transfer has been registered or is exempt from
        registration under the Securities Act and any applicable state
        securities laws.

        Section 3.      Adjustment of Exercise Price and Number of Shares. In
order to prevent dilution of the rights granted under this Warrant, the Exercise
Price shall be subject to adjustment from time to time as provided in this
Section 3, and the number of shares of Common Stock issuable upon exercise of
this Warrant shall be subject to adjustment from time to time as provided in
this Section 3.

                (a)     Subdivision or Combination of Common Stock. If the
        Company at any time subdivides (by any stock split, stock dividend,
        recapitalization or otherwise) one or more classes of its outstanding
        shares of Common Stock into a greater number of shares, the Exercise
        Price in effect immediately prior to such subdivision shall be

<PAGE>   13

        proportionately decreased and the number of shares of Common Stock
        issuable upon exercise of this Warrant shall be proportionately
        increased. If the Company at any time combines (by reverse stock split
        or otherwise) one or more classes of its outstanding shares of Common
        Stock into a smaller number of shares, the Exercise Price in effect
        immediately prior to such combination shall be proportionately increased
        and the number of shares of Common Stock issuable upon exercise of this
        Warrant shall be proportionately decreased.

                (b)     Dividends and Stock Repurchases. If the Company shall
        declare, pay or distribute dividends upon the Common Stock (excluding a
        dividend referred to in Section 3(a)) in any calendar year which, in the
        aggregate, exceed 5% of the Market Price of the Common Stock on the date
        of declaration, then the Exercise Price shall be decreased by
        multiplying the Exercise Price immediately prior to such decrease by a
        fraction, (A) the denominator of which equals the product of (1) the
        Exercise Price immediately prior to such decrease multiplied by (2) the
        number of shares of Common Stock outstanding at such time and (B) the
        numerator of which equals the denominator as determined pursuant to
        clause (A) above minus the amount by which all such dividends for such
        calendar year, in the aggregate, exceed 5% of the Market Price of the
        Common Stock on such date of declaration. Any such decrease shall take
        effect on the record date for the dividend. If the Company shall
        repurchase shares of Common Stock for a per share consideration which
        exceeds the Exercise Price in effect immediately prior to the first such
        repurchase, then the Exercise Price shall be adjusted in accordance with
        the foregoing provisions, as if, in lieu of such repurchase, the Company
        had (i) paid a dividend having a fair market value equal to the fair
        market value of all property and cash expended in the repurchases and
        (ii) effected a reverse split of the Common Stock in the proportion
        necessary to reduce the number of shares of Common Stock outstanding
        from (A) the number of shares outstanding immediately prior to the first
        such repurchase to (B) the number of shares outstanding immediately
        following all such repurchases.

                (c)     Minimum Adjustment. In the event that any adjustment
        made pursuant to this Section 3 would result in an adjustment to the
        Exercise Price of less than $0.05 per share of Common Stock, no such
        adjustment shall be made and such adjustment shall be carried forward
        and shall be made at the time and together with the next subsequent
        adjustment which, together with any adjustments so carried forward,
        shall amount to an adjustment in the Exercise Price of $0.05 or more per
        share of Common Stock; provided that, upon any adjustment of the
        Exercise Price resulting from (i) the declaration of a dividend upon, or
        the making of any distribution in respect of, any securities of the
        Company payable in Common Stock or Convertible Securities or (ii) the
        reclassification, by subdivision, combination or otherwise, of the
        outstanding shares of Common Stock into a greater or smaller number of
        shares, the $0.05 per share number (or such number as last adjusted)
        shall be proportionately adjusted.

                (d)     Reorganization, Reclassification, Consolidation, Merger
        or Sale. Any recapitalization, reorganization, reclassification,
        consolidation, merger, sale of all or

<PAGE>   14

        substantially all of the Company's assets or other transaction that is
        effected in such a way that holders of Common Stock are entitled to
        receive (either directly or upon subsequent liquidation) stock,
        securities or assets with respect to or in exchange for Common Stock is
        referred to herein as "Organic Change." Prior to the consummation of any
        Organic Change, the Company shall make appropriate provision (in form
        and substance satisfactory to the Registered Holders representing a
        majority of the Common Stock issuable upon exercise of the Warrants then
        outstanding) to insure that the Registered Holders shall thereafter have
        the right to acquire and receive in lieu of or in addition to (as the
        case may be) the shares of Common Stock immediately theretofore issuable
        upon exercise of each Warrant, such shares of stock, securities or
        assets as may be issued or payable with respect to or in exchange for
        the number of shares of Common Stock immediately theretofore issuable
        upon exercise of each Warrant had such Organic Change not taken place.
        In any such case, the Company shall make appropriate provision (in form
        and substance satisfactory to the Registered Holders representing a
        majority of the Common Stock issuable upon exercise of the Warrants then
        outstanding) with respect to the Registered Holders' rights and
        interests to insure that the provisions of this Section 3 shall
        thereafter be applicable to each Warrant (including, without limitation,
        in the case of any such consolidation, merger or sale in which the
        successor entity or purchasing entity is other than the Company, an
        immediate adjustment of the Exercise Price to the value for the Common
        Stock reflected by the terms of such consolidation, merger or sale, and
        a corresponding immediate adjustment in the number of shares of Common
        Stock issuable upon exercise of each Warrant, if the value so reflected
        is less than the Exercise Price in effect immediately prior to such
        consolidation, merger or sale). The Company shall not effect any such
        consolidation, merger or sale, unless prior to the consummation thereof,
        the successor entity (if other than the Company) resulting from
        consolidation or merger or the corporation purchasing such assets
        assumes by written instrument (in form and substance satisfactory to the
        Registered Holders representing a majority of the Common Stock issuable
        upon exercise of the Warrants then outstanding), the obligation to
        deliver to the Registered Holders such shares of stock, securities or
        assets as, in accordance with the foregoing provisions, such holder may
        be entitled to acquire.

                (e)     Notices.

                        (i)     Immediately upon any adjustment of the Exercise
                Price, the Company shall give written notice thereof to the
                Registered Holders, setting forth in reasonable detail and
                certifying the calculation of such adjustment.

                        (ii)    The Company shall give written notice to the
                Registered Holders at least 20 days prior to the date on which
                the Company closes its books or takes a record (A) with respect
                to any dividend or distribution upon the Common Stock, (B) with
                respect to any pro rata subscription offer to holders of Common
                Stock or (C) for determining rights to vote with respect to any
                Organic Change, dissolution or liquidation.

<PAGE>   15

                        (iii)   The Company shall also give written notice to
                the Registered Holders at least 20 days prior to the date on
                which any Organic Change, dissolution or liquidation shall take
                place.

        averaged over a period of 21 days consisting of the day as of which
        "Market Price" is being determined and the 20 consecutive business days
        prior to such day; provided that, if such security is listed on any
        national securities exchange, the term "business days" as used in this

        If at any time such security is not listed on any national securities
        exchange or the NASDAQ National Market System or quoted in the NASDAQ
        System or the domestic over-the-counter market, the "Market Price" shall

        Section 5.      Company Representations and Warranties. The Company
represents and warrants to Registered Holder as follows:

                (a)     Due Organization. The Company has been duly organized
        and is validly existing and in good standing under the laws of the State
        of Delaware, and is qualified to do business and in good standing in all
        jurisdictions where such qualification is necessary to carry on its
        business as now conducted or as proposed by it to be conducted on the
        date hereof, except where failure to so qualify would not have a
        material adverse effect on the financial position or results of
        operations of the Company or any adverse effect on the ability of the
        Company to carry out its obligations under this Warrant.

                (b)     Due Authorization. The Company has full power and
        authority to issue this Warrant. The execution, delivery and issuance by
        the Company of this Warrant have been duly and validly approved by all
        necessary corporate or other applicable action and no other actions or
        proceedings on the part of the Company are necessary to authorize this
        Warrant. This Warrant constitutes the legal, valid and binding
        obligation of the Company, enforceable against the Company in accordance
        with its terms, except as such enforceability may be limited by
        applicable bankruptcy, insolvency, moratorium, reorganization or similar
        laws in effect which affect the enforcement of creditors' rights
        generally and by equitable limitations on the availability of specific
        remedies.

                (c)     Capitalization. As of the date hereof, the authorized
        capital stock of the Company consists of 100,000,000 shares of Common
        Stock, of which [10,199,000] 16,897,312 shares of Common Stock are
        currently issued and outstanding. Except as contemplated by this
        Warrant, there are no securities convertible or exchangeable for shares
        of Common Stock or any rights or options to subscribe for or purchase
        any shares of Common Stock or securities convertible or exchangeable for
        shares of Common Stock.

<PAGE>   18

                (d)     Issuance of Shares. The Common Stock issuable hereunder,
        when issued in accordance with the provisions of this Warrant, will be
        duly and validly authorized and issued and will be fully paid and

        issued in compliance with all applicable federal and state securities
        laws.

        Section 6.      No Voting Rights; Limitations of Liability. This Warrant
shall not entitle any Registered Holder to any voting rights or other rights as
a stockholder of the Company. No provision hereof, in the absence of affirmative
action by a Registered Holder to purchase Common Stock, and no enumeration
herein of the rights or privileges of the Registered Holders shall give rise to
any liability of a Registered Holder for the Exercise Price of Common Stock
issuable upon exercise of this Warrant or as a stockholder of the Company.

        Section 7.      Piggyback Registrations.

                (a)     If the Company proposes to register any of its common
        equity securities or any securities convertible into its common equity
        securities under the Securities Act (other than pursuant to (i) a
        registration on Form S-4 or any successor form, or (ii) an offering of
        securities in connection with an employee benefit, share dividend, share
        ownership or dividend reinvestment plan) and the registration form to be
        used may be used for the registration of Registrable Shares, the Company
        will give prompt written notice to all holders of Registrable Shares of
        its intention to effect such a registration (each a "Piggyback Notice")
        and, subject to subparagraph 7(c) below, the Company will include in
        such registration all Registrable Shares with respect to which the
        Company has received written requests for inclusion therein within 15
        business days after the date of sending the Piggyback Notice (a
        "Piggyback Registration"), unless, if the Piggyback Registration is not
        an underwritten offering, the Company in its reasonable judgement
        determines that, or in the case of an underwritten Piggyback
        Registration, the managing underwriters advise the Company in writing
        that in their opinion, the inclusion of Registrable Shares would
        adversely interfere with such offering, affect the Company's securities
        in the public markets, or otherwise adversely affect the Company.
        Nothing herein shall affect the right of the Company to withdraw any
        such registration in its sole discretion.

                (b)     If a Piggyback Registration is a primary registration
        on behalf of the Company and, if the Piggyback Registration is not an
        underwritten offering, the Company in its reasonable judgement
        determines that, or in the case of an underwritten Piggyback
        Registration, the managing underwriters advise the Company in writing
        that in their opinion, the number of securities requested to be included
        in such registration exceeds the number which can be sold in an orderly
        manner within a price range acceptable to the Company, the Company will
        include in such registration (i) first, the securities the Company
        proposes to sell and (ii) second, the Registrable Shares requested to be
        included in such Registration and any other securities requested to be
        included in such registration, pro rata among the holders of Registrable
        Shares requesting such

<PAGE>   19

        registration and the holders of such other securities on the basis of
        the number of Shares requested for inclusion in such registration by
        each such holder.

                (c)     If a Piggyback Registration is a secondary registration
        on behalf of holders of the Company's securities other than the holders
        of Registrable Shares, and, if the Piggyback Registration is not an
        underwritten offering, the Company determines that, or in the case of an
        underwritten Piggyback Registration, the managing underwriters advise
        the Company in writing that in their opinion, the number of securities
        requested to be included in such registration exceeds the number which
        can be sold in an orderly manner in such offering within a price range
        acceptable to the holders initially requesting such registration, the
        Company will include in such registration the securities requested to be
        included therein by the holders requesting such registration and the
        Registrable Shares requested to be included in such registration, pro
        rata among the holders of securities requesting such registration on the
        basis of the number of Shares requested for inclusion in such
        registration by each such holder.

                (d)     In the case of an underwritten Piggyback Registration,
        the Company will have the right to select the investment banker(s) and
        manager(s) to administer the offering. If requested by the underwriters
        for any underwritten offerings by Registered Holders, under a
        registration requested pursuant to Section 7(a), the Company will enter
        into a customary underwriting agreement with such underwriters for such
        offering, to contain such representations and warranties by the Company
        and such other terms which are customarily contained in agreements of
        this type. The Registered Holders shall be a party to such underwriting
        agreement and may, at their option, require that any or all of the
        conditions precedent to the obligations of such underwriters under such
        underwriting agreement be conditions precedent to the obligations of
        Registered Holders. The Registered Holders shall not be required to make
        any representations or warranties to or agreement with the Company or
        the underwriters other than representations, warranties or agreements
        regarding the Registered Holders and the Registered Holders' intended
        method of distribution and any other representation or warranties
        required by law.

        Section 8.      Registration Procedures.

                (a)     The Company shall promptly notify the Registered
        Holders of the occurrence of the following events:

                        (i)     when any registration statement relating to the
                Registrable Shares or post-effective amendment thereto filed
                with the Commission has become effective;

                        (ii)    the issuance by the Commission of any stop
                order suspending the effectiveness of any registration statement
                relating to the Registrable Shares;

<PAGE>   20

                        (iii)   the Company's receipt of any notification of the
                suspension of the qualification of any Registrable Shares
                covered by a registration statement for sale in any
                jurisdiction; and

                        (iv)    the existence of any event, fact or
                circumstance that results in a registration statement or
                prospectus relating to Registrable Shares or any document
                incorporated therein by reference containing an untrue statement
                of material fact or omitting to state a material fact required
                to be stated therein or necessary to make the statements therein
                not misleading during the distribution of securities.

        The Company agrees to use its reasonable best efforts to obtain the
withdrawal of any order suspending the effectiveness of any such registration
statement or any state qualification as promptly as possible. The Registered
Holder agrees by acquisition of the Registrable Shares that upon receipt of any
notice from the Company of the occurrence of any event of the type described in
Section 8(a)(ii), (iii) or (iv) to immediately discontinue its disposition of
Registrable Shares pursuant to any registration statement relating to such
securities until the Registered Holder's receipt of written notice from the
Company that such disposition may be made.

                (b)     The Company shall provide to the Registered Holders, at
        no cost to the Registered Holders, a copy of the registration statement
        and any amendment thereto used to effect the Registration of the
        Registrable Shares, each prospectus contained in such registration
        statement or post-effective amendment and any amendment or supplement
        thereto and such other documents as the requesting Registered Holders
        may reasonably request in order to facilitate the disposition of the
        Registrable Shares covered by such registration statement. The Company
        consents to the use of each such prospectus and any supplement thereto
        by the Registered Holders in connection with the offering and sale of
        the Registrable Shares covered by such registration statement or any
        amendment thereto. The Company shall also file a sufficient number of
        copies of the prospectus and any post-effective amendment or supplement
        thereto with the securities exchange or market on which the Common Stock
        is then listed so as to enable the Registered Holders to have the
        benefits of the prospectus delivery provisions of Rule 153 under the
        Securities Act.

                (c)     The Company agrees to use its reasonable best efforts
        to cause the Registrable Shares covered by a registration statement to
        be registered with or approved by such state securities authorities as
        may be necessary to enable the Registered Holders to consummate the
        disposition of such shares pursuant to the plan of distribution set
        forth in the registration statement.

                (d)     If any event, fact or circumstance requiring an
        amendment to a registration statement relating to the Registrable Shares
        or supplement to a prospectus relating to the Registrable Shares shall
        exist, immediately upon becoming aware thereof the Company agrees to
        notify the Registered Holders and prepare and furnish to the

<PAGE>   21

        Registered Holders a post-effective amendment to the registration
        statement or supplement to the prospectus or any document incorporated
        therein by reference or file any other required document so that, as
        thereafter delivered to the purchasers of the Registrable Shares, the
        prospectus will not contain an untrue statement of a material fact or
        omit to state any material fact required to be stated therein or
        necessary to make the statements therein not misleading.

                (e)     The Company agrees to use its reasonable best efforts
        (including the payment of any listing fees) to obtain the listing of all
        Registrable Shares covered by the registration statement on each
        securities exchange on which securities of the same class or series are
        then listed.

                (f)     The Company agrees to use its reasonable best efforts
        to comply with the Securities Act and the Exchange Act in connection
        with the offer and sale of Registrable Shares pursuant to a registration
        statement, and, as soon as reasonably practicable following the end of
        any fiscal year during which a registration statement effecting a
        Registration of the Registrable Shares shall have been effective, to
        make available to its security holders an earnings statement satisfying
        the provisions of Section 11(a) of the Securities Act.

                (g)     The Company agrees to cooperate with the selling
        Registered Holders to facilitate the timely preparation and delivery of
        certificates representing Registrable Shares to be sold pursuant to a
        Registration and not bearing any Securities Act legend; and enable
        certificates for such Registrable Shares to be issued for such numbers
        of shares and registered in such names as the Registered Holders may
        reasonably request at least two business days prior to any sale of
        Registrable Shares.

        Section 9.      Expenses of Registration. The Company shall pay all
Registration Expenses incurred in connection with the registration,
qualification or compliance pursuant to Sections 7 and 8 hereof. All Selling
Expenses incurred in connection with the sale of Registrable Shares by any of
the Registered Holders shall be borne by the Registered Holder selling such
Registrable Shares. Each Registered Holder shall pay the expenses of its own
counsel.

        Section 10.     Indemnification.

                (a)     The Company will indemnify each Registered Holder, each
        Registered Holder's officers and directors, and each person controlling
        such Registered Holder within the meaning of Section 15 of the
        Securities Act, against all expenses, claims, losses, damages and
        liabilities (including reasonable legal expenses), arising out of or
        based on any untrue statement (or alleged untrue statement) of a
        material fact contained in any registration statement or prospectus
        relating to the Registrable Shares, or any amendment or supplement
        thereto, or based on any omission (or alleged omission) to state therein
        a material fact required to be stated therein or necessary to make the

<PAGE>   22

        statements therein not misleading, provided, however, that the Company
        will not be liable in any such case to the extent that any such claim,
        loss, damage, liability or expense arises out of or is based on any
        untrue statement or omission or alleged untrue statement or omission,
        made in reliance upon and in conformity with information furnished in
        writing to the Company by such Registered Holder for inclusion therein.

                (b)     Each Registered Holder will indemnify the Company, each
        of its directors and each of its officers who signs the registration
        statement, each underwriter, if any, of the Company's securities covered
        by such registration statement, and each person who controls the Company
        or such underwriter within the meaning of Section 15 of the Securities
        Act, against all claims, losses, damages and liabilities (including
        reasonable legal fees and expenses) arising out of or based on any
        untrue statement (or alleged untrue statement) of a material fact
        contained in any such registration statement or prospectus, or any
        amendment or supplement thereto, 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, 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 or prospectus, in reliance upon and in
        conformity with information furnished in writing to the Company by such
        Registered Holder for inclusion therein.

                (c)     Each party entitled to indemnification under this
        Section 10 (the "Indemnified Party") shall give notice to the party
        required to provide indemnification (the "Indemnifying Party") promptly
        after such Indemnified Party has actual knowledge of any claim as to
        which indemnity may be sought, but the omission to so notify the
        Indemnifying Party shall not relieve it from any liability which it may
        have to the Indemnified Party pursuant to the provisions of this Section
        10 except to the extent of the actual damages suffered by such delay in
        notification. The Indemnifying Party shall assume the defense of such
        action, including the employment of counsel to be chosen by the
        Indemnifying Party to be reasonably satisfactory to the Indemnified
        Party, and payment of expenses. The Indemnified Party shall have the
        right to employ its own counsel in any such case, but the legal fees and
        expenses of such counsel shall be at the expense of the Indemnified
        Party, unless the employment of such counsel shall have been authorized
        in writing by the Indemnifying Party in connection with the defense of
        such action, or the Indemnifying Party shall not have employed counsel
        to take charge of the defense of such action or the Indemnified Party
        shall have reasonably concluded that there may be defenses available to
        it or them which are different from or additional to those available to
        the Indemnifying Party (in which case the Indemnifying Party shall not
        have the right to direct the defense of such action on behalf of the
        Indemnified Party), in any of which events such fees and expenses shall
        be borne by the Indemnifying Party. 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

<PAGE>   23

        claimant or plaintiff to such Indemnified Party of a release from all
        liability in respect to such claim or litigation.

                (d)     In no event shall any Registered Holder be liable for
        any expenses, claims, losses, damages or liabilities pursuant to this
        Section 10 in excess of the net proceeds to such Registered Holder of
        any Registrable Shares sold by such Registered Holder.

        Section 11.     Information to be Furnished by Registered Holders. Each
Registered Holder shall furnish to the Company such information as the Company
may reasonably request and as shall be required in connection with the
Registration and related proceedings referred to in Section 9 hereof. If any
Registered Holder fails to provide the Company with such information within 15
days of receipt of the Company's request, the Company's obligations under
Section 9 hereof, as applicable, with respect to such Registered Holder or the
Registrable Shares owned by such Registered Holder shall be suspended until such
Registered Holder provides such information.

        Section 12.     Rule 144 Sales.

                (a)     The Company covenants that it will file the reports
        required to be filed by the Company under the Exchange Act so as to
        enable any Registered Holder to sell Registrable Shares pursuant to Rule
        144 under the Securities Act.

                (b)     In connection with any sale, transfer or other
        disposition by any Registered Holder of any Registrable Shares pursuant
        to Rule 144 under the Securities Act, the Company shall cooperate with
        such Registered Holder to facilitate the timely preparation and delivery
        of certificates representing Registrable Shares to be sold, and enable
        certificates for such Registrable Shares to be for such number of shares
        and registered in such names as the selling Registered Holder may
        reasonably request at least two business days prior to any sale of
        Registrable Shares.

        Section 13.     Replacement. Upon receipt of evidence reasonably
satisfactory to the Company (an affidavit of the Registered Holder shall be
satisfactory) of the ownership and the loss, theft, destruction or mutilation of
any certificate evidencing this Warrant, and in the case of any such loss, theft
or destruction, upon receipt of indemnity reasonably satisfactory to the Company
(provided that, if the holder is a financial institution or other institutional
investor, its own agreement shall be satisfactory), or, in the case of any such
mutilation upon surrender of such certificate, the Company shall (at its
expense) execute and deliver in lieu of such certificate a new certificate of
like kind representing the same rights represented by such lost, stolen,
destroyed or mutilated certificate and dated the date of such lost, stolen,
destroyed or mutilated certificate.

        Section 14.     Notices. Except as otherwise expressly provided herein,
any notice, request, instruction or other document to be given hereunder shall

Warrant may be amended, modified or supplemented, but only if the Company has
obtained the written consent of the Registered Holders representing a majority
of the shares of Common Stock issuable upon exercise of the Warrants then
