                         COMMON STOCK PURCHASE AGREEMENT

         COMMON STOCK PURCHASE AGREEMENT (the "Agreement"), dated as of December
7, 2000 by and between U.S. PLASTIC LUMBER CORP., a Nevada corporation (the
"Company"), and FUSION CAPITAL FUND II, LLC (together with its permitted
assigns, the "Buyer"). Capitalized terms used herein and not otherwise defined
herein are defined in Section 10 hereof.

                                    WHEREAS:

         Subject to the terms and conditions set forth in this Agreement, the
Company wishes to sell to the Buyer, and the Buyer wishes to buy from the
Company, up to Six Million Dollars ($6,000,000) of the Company's common stock,
par value $.0001 per share (the "Common Stock"). The shares of Common Stock to
be purchased hereunder are referred to herein as the "Purchase Shares." In
addition, as set forth in Section 1(g) hereof, the Company may, in its sole
discretion, at any time after the date hereof and until 20 Trading Days after
such date as the Available Amount is equal to $0, deliver an irrevocable written
notice to the Buyer stating that the Company elects to enter into an additional
Common Stock Purchase Agreement with the Buyer for the purchase of Six Million
Dollars ($6,000,000) of additional Common Stock.

         NOW THEREFORE, the Company and the Buyer hereby agree as follows:

         1. PURCHASE OF COMMON STOCK.

         Subject to the terms and conditions set forth in Sections 6, 7 and 9
below, the Company hereby agrees to sell to the Buyer, and the Buyer hereby
agrees to purchase from the Company, shares of Common Stock as follows:

         (a) COMMENCEMENT OF PURCHASES OF COMMON STOCK. The purchase and sale of
Common Stock hereunder shall commence (the "Commencement") within five (5)
Trading Days following the date of satisfaction (or waiver) of the conditions to
the Commencement set forth in Sections 6 and 7 below (or such later date as is
mutually agreed to by the Company and the Buyer), (the date of such
Commencement, the "Commencement Date").

         (b) BUYER'S PURCHASE RIGHTS AND OBLIGATIONS. Subject to the provisions
of Sections 1(d), the Buyer: (i) shall purchase shares of Common Stock during
each Monthly Period equal to the Monthly Base Amount at the Purchase Price in
accordance with Section 1(e), and (ii) at any time on or after the Maturity
Date, shall have the right to purchase shares of Common Stock up to the entire
remaining Available Amount at the Purchase Price in accordance with Section
1(e). Within three (3) Trading Days of receipt of Purchase Shares, the Buyer
shall pay to the Company an amount equal to the Purchase Amount with respect to
such Purchase Shares as full payment for the purchase of the Purchase Shares so
received. The Company shall not issue any fraction of a share of Common Stock
upon any purchase. All shares of Common Stock (including fractions thereof)
issuable upon a purchase under this Agreement shall be aggregated for purposes
of determining whether the purchase would result in the issuance of a fraction
of a share of Common Stock. If, after the aforementioned aggregation, the
issuance would result in the issuance of a fraction of a share of Common Stock,
the Company shall round such fraction of a share of Common Stock up or down to
the nearest whole share. All payments made under this Agreement shall be made in
lawful money of the United States of America by check or wire transfer of
immediately available funds to such account as the Company may from time to time
designate by written notice in accordance with the

<PAGE>   2

provisions of this Agreement. Whenever any amount expressed to be due by the
terms of this Agreement is due on any day which is not a Trading Day, the same
shall instead be due on the next succeeding day which is a Trading Day.

         (c) COMPANY'S MANDATORY PURCHASE RIGHTS. If (A) the Closing Sale Price
of the Common Stock on each of any five (5) consecutive Trading Days is at least
$3.50 and (B) no Event of Default has occurred and is continuing, then the
Company shall have the right, so long as no Event of Default has occurred and is
continuing and so long as the Sale Price of the Common Stock remains at least
$3.50 at all times thereafter, by delivering written notice (a "Mandatory
Purchase Notice") to the Buyer to require that the Buyer purchase at the
Purchase Price such Available Amount as specified by the Company in the
Mandatory Purchase Notice at any time or from time to time during the next sixty
(60) days on such Trading Days during such sixty (60) days as the Buyer shall
determine. The Company acknowledges and agrees that the Company's mandatory
purchase rights represent an agreement by the Buyer to extend financial
accommodations to the Company. Accordingly, it shall be a condition to the
exercise of the Company's Mandatory Purchase Rights that no Event of Default
shall have occurred and is continuing, and the Company's delivery of a Mandatory
Purchase Notice shall be deemed a representation to the Buyer that no Event of
Default has occurred and is continuing. The Company may revoke a Mandatory
Purchase Notice, in whole or in part, by delivering written notice thereof to
the Buyer (a "Revocation of Mandatory Purchase Notice"). A Revocation of
Mandatory Purchase Notice shall be effective only as to Purchase Notices which
have a Purchase Date later than three (3) Trading Days after receipt by the
Buyer of the Revocation of Mandatory Purchase Notice. Any Purchase Notices
submitted by the Buyer which have a Purchase Date on or prior to the third (3rd)
Trading Day after receipt by the Buyer of the Revocation of Mandatory Purchase
Notice must be honored by the Company as otherwise provided herein.

         (d)      LIMITATIONS ON PURCHASES.

                  (i) EXCHANGE CAP LIMITATION. The Company shall not effect any
         purchase under this Agreement and the Buyer shall not have the right to
         purchase shares of Common Stock under this Agreement to the extent that
         after giving effect to such purchase the "Exchange Cap" shall be deemed
         to be reached. The "Exchange Cap" shall be deemed to be reached at such
         time if, upon submission of a Purchase Notice under this Agreement, the
         issuance of such shares of Common Stock would exceed that number of
         shares of Common Stock which the Company may issue under this Agreement
         without breaching the Company's obligations under the rules or
         regulations of the Principal Market.

                  (ii) LIMITATION ON BENEFICIAL OWNERSHIP. The Company shall not
         effect any purchase under this Agreement and the Buyer shall not have
         the right to purchase shares of Common Stock under this Agreement to
         the extent that after giving effect to such purchase the Buyer together
         with its affiliates would beneficially own in excess of 4.99% of the
         outstanding shares of the Common Stock following such purchase. For
         purposes hereof, the number of shares of Common Stock beneficially
         owned by the Buyer and its affiliates or acquired by the Buyer and its
         affiliates, as the case may be, shall include the number of shares of
         Common Stock issuable in connection with a Purchase Notice under this
         Agreement with respect to which the determination is being made, but
         shall exclude the number of shares of Common Stock which would be
         issuable upon (1) a purchase of the remaining Available Amount which
         has not been submitted for purchase, and (2) exercise or conversion of
         the unexercised or unconverted portion of any other securities of the
         Company (including, without limitation, any warrants) subject to a
         limitation on conversion or exercise analogous to the limitation
         contained herein beneficially owned by the Buyer and its affiliates. If
         the 4.99% limitation is ever reached the Company shall have the option
         to increase such limitation

                                       2
<PAGE>   3

         to 9.99% by delivery of written notice to the Buyer. Thereafter, if the
         9.99% limitation is ever reached this shall not effect or limit the
         Buyer's obligation to purchase the Monthly Base Amount or the Company's
         Mandatory Purchase Rights as otherwise provided in this Agreement. For
         purposes of this Section, in determining the number of outstanding
         shares of Common Stock the Buyer may rely on the number of outstanding
         shares of Common Stock as reflected in (1) the Company's most recent
         Form 10-Q or Form 10-K, as the case may be, (2) a more recent public
         announcement by the Company or (3) any other written communication by
         the Company or its transfer agent setting forth the number of shares of
         Common Stock outstanding. Upon the reasonable written or oral request
         of the Buyer, the Company shall promptly confirm orally and in writing
         to the Buyer the number of shares of Common Stock then outstanding. In
         any case, the number of outstanding shares of Common Stock shall be
         determined after giving effect to any purchases under this Agreement by
         the Buyer since the date as of which such number of outstanding shares
         of Common Stock was reported. Except as otherwise set forth herein, for
         purposes of this Section 1(d)(ii), beneficial ownership shall be
         determined in accordance with Section 13(d) of the Securities Exchange
         Act of 1934, as amended.

                  (iii) COMPANY'S RIGHT TO SUSPEND PURCHASES. If at any time the
         Closing Sale Price of the Common Stock is below the Fixed Purchase
         Price for three consecutive Trading Days, the Company shall have three
         (3) Trading Days from the last day of such three consecutive Trading
         Day Period to give written notice (a "Purchase Suspension Notice") to
         the Buyer suspending any and all purchases by the Buyer under this
         Agreement. The Purchase Suspension Notice shall be effective only for
         Purchase Notices which have a Purchase Date later than three (3)
         Trading Days after receipt of the Purchase Suspension Notice by the
         Buyer. Any Purchase Notices submitted by the Buyer which have a
         Purchase Date on or prior to the third (3rd) Trading Day after receipt
         by the Buyer of the Company's Purchase Suspension Notice must be
         honored by the Company as otherwise provided herein. Such purchase
         suspension shall continue in effect until the earlier of: (A)
         revocation in writing by the Company, at its sole discretion; or (B)
         such time as the Sale Price of the Common Stock is above the Fixed
         Purchase Price. After the delivery to the Buyer of a Purchase
         Suspension Notice from the Company, the Buyer shall no longer be
         obligated to purchase any Purchase Shares from the Company under
         Section 1 of this Agreement.

         (e) MECHANICS OF PURCHASING. The purchase of shares of Common Stock
under this Agreement shall be conducted in the following manner:

                  (i) BUYER'S DELIVERY REQUIREMENTS. To purchase shares of
         Common Stock under this Agreement on any date, the Buyer shall transmit
         by facsimile (or otherwise deliver) on or prior to 11:59 p.m., Central
         Time on such date, a copy of a fully executed notice of purchase
         substantially in the form attached hereto as EXHIBIT A (the "Purchase
         Notice") to the Company.

                  (ii) COMPANY'S RESPONSE. Upon receipt by the Company of a
         Purchase Notice, so long as a Purchase Suspension Notice is not in
         effect with respect to such Purchase Notice under Section 1(d)(iii)
         hereof, the Company shall as soon as practicable, but in no event later
         than one (1) Trading Day after receipt of such Purchase Notice, send
         via facsimile (or otherwise deliver), a confirmation of receipt of such
         Purchase Notice in the form attached hereto as EXHIBIT B (a "Company
         Confirmation of Purchase Notice") to (1) the Buyer and (2) along with a
         copy of the Purchase Notice, the Company's designated transfer agent
         (the "Transfer Agent"), which confirmation shall constitute an
         irrevocable instruction to the Transfer Agent to process such Purchase
         Notice in accordance with the terms herein. Upon receipt by the
         Transfer Agent of a copy of the executed Purchase Notice and a copy of
         the applicable Company Confirmation of

                                       3
<PAGE>   4

         Purchase Notice, the Transfer Agent shall, on the first (1st) Trading
         Day following the date of receipt of the Company Confirmation of
         Purchase Notice, (A) provided the Transfer Agent is participating in
         The Depository Trust Company's ("The DTC") Fast Automated Securities
         Transfer Program, credit such aggregate number of shares of Common
         Stock to which the Buyer shall be entitled to the Buyer's or its
         designee's balance account with The DTC through its Deposit Withdrawal
         At Custodian ("DWAC") system, or (B) if the Transfer Agent is not
         participating in The DTC Fast Automated Securities Transfer Program and
         DWAC system, issue and surrender to a common carrier for overnight
         delivery to the address as specified in the Purchase Notice, a
         certificate, registered in the name of the Buyer or its designee, for
         the number of shares of Common Stock to which the Buyer shall be
         entitled.

                  (iii) DISPUTE RESOLUTION. In the case of a dispute as to the
         determination of the Purchase Price or the arithmetic calculation of
         the Purchase Rate, the Company shall instruct the Transfer Agent to
         issue to the Buyer the number of shares of Common Stock that is not
         disputed and shall submit the disputed determinations or arithmetic
         calculations to the Buyer via facsimile within one (1) Trading Day of
         receipt of the Buyer's Purchase Notice. If the Buyer and the Company
         are unable to agree upon the determination of the Purchase Price or
         arithmetic calculation of the Purchase Rate within one (1) Trading Day
         of such disputed determination or arithmetic calculation being
         submitted to the Buyer, then the Company shall within one (1) Trading
         Day submit via facsimile (A) the disputed determination of the Purchase
         Price to an independent, reputable investment bank selected by the
         Company and approved by the Buyer or (B) the disputed arithmetic
         calculation of the Purchase Rate to the Company's independent, outside
         accountant. The Company shall cause the investment bank or the
         accountant, as the case may be, to perform the determinations or
         calculations and notify the Company and the Buyer of the results no
         later than the fifth (5th) day after the date it receives the disputed
         determinations or calculations. Such investment bank's or accountant's
         determination or calculation, as the case may be, shall be binding upon
         all parties absent manifest error.

                  (iv) RECORD HOLDER. The person or persons entitled to receive
         the shares of Common Stock issuable upon a purchase under this
         Agreement shall be treated for all purposes as the record holder or
         holders of such shares of Common Stock on the Purchase Date.

                  (v) COMPANY'S FAILURE TO TIMELY DELIVER SHARES. If within ten
         (10) Trading Days after the Company's receipt of a copy of the Purchase
         Notice properly submitted in accordance with the term and conditions of
         this Agreement (subject to extension in accordance with Section
         1(e)(iii) for a good faith dispute made in accordance with the terms of
         Section 1(e)(iii)) (the "Share Delivery Period"), the Transfer Agent
         shall fail to issue Purchase Shares via credit to the Buyer's account
         with DTC for the number of Purchase Shares to which such Buyer is
         entitled upon such Buyer's submission of the applicable Purchase Notice
         (a "Purchase Failure"), in addition to all other available remedies
         which such Buyer may pursue under applicable laws and this Agreement
         (including indemnification obligations of the Company set forth in
         Section 8 hereof), the Company shall pay in cash, on demand, additional
         damages to the Buyer for each day after such tenth (10th) Trading Day
         that the issuance of such Purchase Shares is not timely effected, in an
         amount equal to 1.5% of the product of (I) the number of Purchase
         Shares not issued to the Buyer on a timely basis pursuant to Section
         1(e)(ii) and to which such Buyer is entitled and (II) the Closing Sale
         Price of the Common Stock on the Purchase Date.

                  (vi) BOOK ENTRY. Notwithstanding anything to the contrary set
         forth herein, upon purchase of any portion of the Available Amount in
         accordance with the terms hereof, the Buyer

                                       4
<PAGE>   5

         shall not be required to physically surrender this Agreement to the
         Company. The Buyer and the Company shall each maintain records showing
         the remaining Available Amount and the dates and Purchase Amounts for
         each purchase or shall use such other method, reasonably satisfactory
         to the Buyer and the Company, so as not to require physical surrender
         of this Agreement upon each purchase. The Buyer and any assignee, by
         acceptance of this Agreement, acknowledge and agree that, by reason of
         the provisions of this paragraph, following purchase of any portion of
         the Available Amount, the remaining Available Amount under this
         Agreement shall be less than the aggregate Available Amount set forth
         on the face hereof.

         (f) TAXES. The Company shall pay any and all taxes that may be payable
with respect to the issuance and delivery of any shares of Common Stock to the
Buyer made under of this Agreement.

         (g) OPTION FOR SECOND TRANCHE; ADDITIONAL COMMON STOCK PURCHASE
AGREEMENT. The Company may, in its sole discretion, at any time after the date
hereof and until 20 Trading Days after such date as the Available Amount is
equal to $0 (the "Second Tranche Expiration Date"), deliver an irrevocable
written notice (the "Second Tranche Notice") to the Buyer stating that the
Company elects to enter into an additional Common Stock Purchase Agreement (the
"Second Common Stock Purchase Agreement") with the Buyer for the purchase of Six
Million Dollars ($6,000,000) of additional Common Stock. It is agreed and
acknowledged by the parties hereto that entering into the Second Common Stock
Purchase Agreement shall be at the option of the Company in its sole discretion
until such time as the Company shall have delivered the Second Tranche Notice to
the Buyer. The Buyer shall not be obligated to enter into the Second Common
Stock Purchase Agreement unless the Company has delivered the Second Tranche
Notice prior to the Second Tranche Expiration Date. The Second Common Stock
Purchase Agreement may not be entered into until the aggregate Available Amount
under this Agreement is fully used to buy Purchase Shares hereunder. Upon
delivery of the Second Tranche Notice to the Buyer prior to the Second Tranche
Expiration Date, the Buyer and the Company shall be obligated to enter into the
Second Common Stock Purchase Agreement no later than the date that is 10 Trading
Days after the Second Tranche Expiration Date. If the Buyer and the Company have
not entered into the Second Common Stock Purchase Agreement by the date that is
10 Trading Days after the Second Tranche Expiration Date, the Buyer shall not be
obligated to enter into such additional Common Stock Purchase Agreement. The
terms and conditions of the Second Common Stock Purchase Agreement shall be in
form and substance identical in all respects to this Agreement, provided,
however, that for purposes of the Second Common Stock Purchase Agreement, (i)
this Section 1(g) shall be omitted, and (ii) for purposes of calculating the
number of Commitment Shares in Sections 7(b), 11(k)(ii) and 11(k)(iii) the
Commitment Shares shall be equal to 8% of Six Million Dollars ($6,000,000)
divided by the arithmetic average of the Closing Bid Prices of the Common Stock
for the ten (10) consecutive Trading Days immediately preceding the date that
the Second Tranche Notice is delivered to the Buyer. Such second tranche
Commitment Shares shall be held by the Buyer until the Second Common Stock
Purchase Agreement has been terminated.

         2. BUYER'S REPRESENTATIONS AND WARRANTIES.

         The Buyer represents and warrants to the Company that:

         (a) INVESTMENT PURPOSE. The Buyer is entering into this Agreement and
acquiring the Commitment Shares (as defined in Section 7(b) hereof) (this
Agreement and the Commitment Shares are collectively referred to herein as the
"Securities"), for its own account for investment only and not with a view
towards, or for resale in connection with, the public sale or distribution
thereof; provided however, by making the representations herein, the Buyer does
not agree to hold any of the Securities for any minimum or other specific term.

                                       5
<PAGE>   6

         (b) ACCREDITED INVESTOR STATUS. The Buyer is an "accredited investor"
as that term is defined in Rule 501(a)(3) of Regulation D.

         (c) RELIANCE ON EXEMPTIONS. The Buyer understands that the Securities
are being offered and sold to it in reliance on specific exemptions from the
registration requirements of United States federal and state securities laws and
that the Company is relying in part upon the truth and accuracy of, and the
Buyer's compliance with, the representations, warranties, agreements,
acknowledgments and understandings of the Buyer set forth herein in order to
determine the availability of such exemptions and the eligibility of the Buyer
to acquire the Securities.

         (d) INFORMATION. The Buyer has been furnished with all materials
relating to the business, finances and operations of the Company and materials
relating to the offer and sale of the Securities that have been reasonably
requested by the Buyer, including, without limitation, the SEC Documents (as
defined in Section 3(f) hereof). The Buyer understands that its investment in
the Securities involves a high degree of risk. The Buyer (i) is able to bear the
economic risk of an investment in the Securities including a total loss, (ii)
has such knowledge and experience in financial and business matters that it is
capable of evaluating the merits and risks of the proposed investment in the
Securities and (iii) has had an opportunity to ask questions of and receive
answers from the officers of the Company concerning the financial condition and
business of the Company and others matters related to an investment in the
Securities. Neither such inquiries nor any other due diligence investigations
conducted by the Buyer or its representatives shall modify, amend or affect the
Buyer's right to rely on the Company's representations and warranties contained
in Section 3 below. The Buyer has sought such accounting, legal and tax advice
as it has considered necessary to make an informed investment decision with
respect to its acquisition of the Securities.

         (e) NO GOVERNMENTAL REVIEW. The Buyer understands that no United States
federal or state agency or any other government or governmental agency has
passed on or made any recommendation or endorsement of the Securities or the
fairness or suitability of the investment in the Securities nor have such
authorities passed upon or endorsed the merits of the offering of the
Securities.

         (f) TRANSFER OR RESALE. The Buyer understands that except as provided
in the Registration Rights Agreement (as defined in Section 6(a) hereof): (i)
the Securities have not been and are not being registered under the 1933 Act or
any state securities laws, and may not be offered for sale, sold, assigned or
transferred unless (A) subsequently registered thereunder or (B) an exemption
exists permitting such Securities to be sold, assigned or transferred without
such registration; (ii) any sale of the Securities made in reliance on Rule 144
may be made only in accordance with the terms of Rule 144 and further, if Rule
144 is not applicable, any resale of the Securities under circumstances in which
the seller (or the person through whom the sale is made) may be deemed to be an
underwriter (as that term is defined in the 1933 Act) may require compliance
with some other exemption under the 1933 Act or the rules and regulations of the
SEC thereunder; and (iii) neither the Company nor any other person is under any
obligation to register such securities under the 1933 Act or any state
securities laws or to comply with the terms and conditions of any exemption
thereunder.

         (g) VALIDITY; ENFORCEMENT. This Agreement has been duly and validly
authorized, executed and delivered on behalf of the Buyer and is a valid and
binding agreement of the Buyer enforceable against the Buyer in accordance with
its terms, subject as to enforceability to general principles of equity and to
applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and
other similar laws relating to, or affecting generally, the enforcement of
applicable creditors' rights and remedies.

                                       6

         (h) RESIDENCY. The Buyer is a resident of the State of Illinois.

         (i) NO PRIOR SHORT SELLING. The Buyer represents and warrants to the
Company that at no time prior to the date of this Agreement has any of the
Buyer, its agents, associates, representatives or affiliates engaged in or
effected, in any manner whatsoever, directly or indirectly, any (i) "short sale"
(as such term is defined in Rule 3b-3 of the 1934 Act) of the Common Stock or
(ii) hedging transaction, which establishes a net short position with respect to
the Common Stock.

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         The Company represents and warrants to the Buyer that:

         (a) ORGANIZATION AND QUALIFICATION. The Company and its "Subsidiaries"
(which for purposes of this Agreement means any entity in which the Company,
directly or indirectly, owns 50% or more of the voting stock or capital stock or
other similar equity interests) are corporations duly organized and validly
existing in good standing under the laws of the jurisdiction in which they are
incorporated, and have the requisite corporate power and authority to own their
properties and to carry on their business as now being conducted. Each of the
Company and its Subsidiaries is duly qualified as a foreign corporation to do
business and is in good standing in every jurisdiction in which its ownership of
property or the nature of the business conducted by it makes such qualification
necessary, except to the extent that the failure to be so qualified or be in
good standing could not reasonably be expected to have a Material Adverse
Effect. As used in this Agreement, "Material Adverse Effect" means any material
adverse effect on any of: (i) the business, properties, assets, operations,
results of operations or financial condition of the Company and its
Subsidiaries, if any, taken as a whole, (ii) the value of the Common Stock,
(iii) the transactions contemplated hereby or by the agreements and instruments
to be entered into in connection herewith or (iv) the authority or ability of
the Company to perform its obligations under the Transaction Documents (as
defined in Section 3(b) hereof). The Company has no Subsidiaries except as set
forth on Schedule 3(a).

         (b) AUTHORIZATION; ENFORCEMENT; VALIDITY. (i) The Company has the
requisite corporate power and authority to enter into and perform its
obligations under this Agreement, the Registration Rights Agreement (as defined
in Section 6(a) hereof) and each of the other agreements entered into by the
parties hereto in connection with the transactions contemplated by this
Agreement (collectively, the "Transaction Documents"), and to issue the

Market applicable to the Company or any of its Subsidiaries) or by which any
property or asset of the Company or any of its Subsidiaries is bound or

indebtedness, indenture, instrument, judgment, decree or order or any statute,
rule or regulation applicable to the Company or its Subsidiaries, except for

reasonably be expected to have a Material Adverse Effect. The business of the
Company and its Subsidiaries is not being conducted, and shall not be conducted,
in violation of any law, ordinance, regulation of any governmental entity,
except for possible violations, the sanctions for which either individually or
in the aggregate could not reasonably be expected to have a Material Adverse
Effect. Except as specifically contemplated by this Agreement and as required
under the 1933 Act, the Company is not required to obtain any consent,
authorization or order of, or make any filing or registration with, any court or

1934, as amended (the "1934 Act") (all of the foregoing filed prior to the date
hereof and all exhibits included therein and financial statements and schedules
thereto and documents incorporated by reference therein being hereinafter
referred to as the "SEC Documents"). As of their respective dates (except as
they have been correctly amended), the SEC Documents complied in all material
respects with the requirements of the 1934 Act and the rules and regulations of
the SEC promulgated thereunder applicable to the SEC Documents, and none of the
SEC Documents, at the time they were filed with the SEC (except as they may have
been correctly amended), contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. As of their respective dates (except as they
have been correctly amended), the financial statements of the Company included
in the SEC Documents complied as to form in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto. Such financial statements have been prepared in
accordance with generally accepted accounting principles, consistently applied,
during the periods involved (except (i) as may be otherwise indicated in such
financial statements or the notes thereto or (ii) in the case of unaudited
interim statements, to the extent they may exclude footnotes or may be condensed
or summary statements) and fairly present in all material respects the financial
position of the Company as of the dates thereof and the results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal year-end audit adjustments).

         (g) ABSENCE OF CERTAIN CHANGES. Except as disclosed in Schedule 3(g),
since September 30, 2000, there has been no material adverse change in the
business, properties, operations, financial condition or results of operations
of the Company or its Subsidiaries. The Company has not taken any steps, and

<PAGE>   10

does not currently expect to take any steps, to seek protection pursuant to any
bankruptcy law nor does the Company or any of its Subsidiaries have any
knowledge or reason to believe that its creditors intend to initiate involuntary
bankruptcy proceedings.

         (h) ABSENCE OF LITIGATION. There is no action, suit, proceeding,
inquiry or investigation before or by any court, public board, government
agency, self-regulatory organization or body pending or, to the knowledge of the
Company or any of its Subsidiaries, threatened against or affecting the Company,
the Common Stock or any of the Company's Subsidiaries or any of the Company's or
the Company's Subsidiaries' officers or directors in their capacities as such,
which could reasonably be expected to have a Material Adverse Effect. A
description of each action, suit, proceeding, inquiry or investigation before or
by any court, public board, government agency, self-regulatory organization or
body which, as of the date of this Agreement, is pending or threatened in
writing against or affecting the Company, the Common Stock or any of the
Company's Subsidiaries or any of the Company's or the Company's Subsidiaries'
officers or directors in their capacities as such, is set forth in Schedule
3(h).

         (i) ACKNOWLEDGMENT REGARDING BUYER'S STATUS. The Company acknowledges
and agrees that the Buyer is acting solely in the capacity of arm's length
purchaser with respect to the Transaction Documents and the transactions
contemplated hereby and thereby. The Company further acknowledges that the Buyer
is not acting as a financial advisor or fiduciary of the Company (or in any
similar capacity) with respect to the Transaction Documents and the transactions
contemplated hereby and thereby and any advice given by the Buyer or any of its
representatives or agents in connection with the Transaction Documents and the
transactions contemplated hereby and thereby is merely incidental to the Buyer's
purchase of the Securities. The Company further represents to the Buyer that the
Company's decision to enter into the Transaction Documents has been based solely
on the independent evaluation by the Company and its representatives and
advisors.

         (j) NO GENERAL SOLICITATION. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has engaged in any
form of general solicitation or general advertising (within the meaning of
Regulation D under the 1933 Act) in connection with the offer or sale of the
Securities.

         (k) NO INTEGRATED OFFERING. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf has, directly or
indirectly, made any offers or sales of any security or solicited any offers to
buy any security, under circumstances that would require registration of any of
the Securities under the 1933 Act or cause this offering of the Securities to be
integrated with prior offerings by the Company for purposes of the 1933 Act or
any applicable shareholder approval provisions, including, without limitation,
under the rules and regulations of any exchange or automated quotation system on
which any of the securities of the Company are listed or designated, nor will
the Company or any of its Subsidiaries take any action or steps that would
require registration of any of the Securities under the 1933 Act or cause the
offering of the Securities to be integrated with other offerings.

         (l) DILUTIVE EFFECT. The Company understands and acknowledges that the
number of Purchase Shares purchasable under this Agreement will increase in
certain circumstances. The Company further acknowledges that its obligation to
issue Purchase Shares under this Agreement in accordance with the term and
conditions hereof is absolute and unconditional regardless of the dilutive
effect that such issuance may have on the ownership interests of other
shareholders of the Company.

         (m) INTELLECTUAL PROPERTY RIGHTS. The Company and its Subsidiaries own
or possess adequate rights or licenses to use all material trademarks, trade
names, service marks, service mark registrations, service names, patents, patent
rights, copyrights, inventions, licenses, approvals, governmental

                                       10
<PAGE>   11

authorizations, trade secrets and rights necessary to conduct their respective
businesses as now conducted. Except as set forth on Schedule 3(m), none of the
Company's material trademarks, trade names, service marks, service mark
registrations, service names, patents, patent rights, copyrights, inventions,
licenses, approvals, government authorizations, trade secrets or other
intellectual property rights have expired or terminated, or, by the terms and
conditions thereof, could expire or terminate within two years from the date of
this Agreement. The Company and its Subsidiaries do not have any knowledge of
any infringement by the Company or its Subsidiaries of any material trademark,
trade name rights, patents, patent rights, copyrights, inventions, licenses,
service names, service marks, service mark registrations, trade secret or other
similar rights of others, or of any such development of similar or identical
trade secrets or technical information by others and, except as set forth on
Schedule 3(m), there is no claim, action or proceeding being made or brought
against, or to the Company's knowledge, being threatened against, the Company or
its Subsidiaries regarding trademark, trade name, patents, patent rights,
invention, copyright, license, service names, service marks, service mark
registrations, trade secret or other infringement, which could reasonably be
expected to have a Material Adverse Effect.

         (n) ENVIRONMENTAL LAWS. The Company and its Subsidiaries (i) are in
compliance with any and all applicable foreign, federal, state and local laws
and regulations relating to the protection of human health and safety, the
environment or hazardous or toxic substances or wastes, pollutants or
contaminants ("Environmental Laws"), (ii) have received all permits, licenses or
other approvals required of them under applicable Environmental Laws to conduct
their respective businesses and (iii) are in compliance with all terms and
conditions of any such permit, license or approval, except where, in each of the
three foregoing clauses, the failure to so comply could not reasonably be
expected to have, individually or in the aggregate, a Material Adverse Effect.

         (o) TITLE. The Company and its Subsidiaries have good and marketable
title in fee simple to all real property and good and marketable title to all
personal property owned by them which is material to the business of the Company
and its Subsidiaries, in each case free and clear of all liens, encumbrances and
defects except such as are described in Schedule 3(o) or such as do not
materially affect the value of such property and do not interfere with the use
made and proposed to be made of such property by the Company and any of its
Subsidiaries. Any real property and facilities held under lease by the Company
and any of its Subsidiaries are held by them under valid, subsisting and
enforceable leases with such exceptions as are not material and do not interfere
with the use made and proposed to be made of such property and buildings by the
Company and its Subsidiaries.

         (p) INSURANCE. The Company and each of its Subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as management of the Company believes to be prudent and
customary in the businesses in which the Company and its Subsidiaries are
engaged. Neither the Company nor any such Subsidiary has been refused any
insurance coverage sought or applied for and neither the Company nor any such
Subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not materially and adversely affect the condition,
financial or otherwise, or the earnings, business or operations of the Company
and its Subsidiaries, taken as a whole.

         (q) REGULATORY PERMITS. The Company and its Subsidiaries possess all
material certificates, authorizations and permits issued by the appropriate
federal, state or foreign regulatory authorities necessary to conduct their
respective businesses, and neither the Company nor any such Subsidiary has
received any notice of proceedings relating to the revocation or modification of
any such certificate, authorization or permit.

                                       11
<PAGE>   12

         (r) TAX STATUS. The Company and each of its Subsidiaries has made or
filed all federal and state income and all other material tax returns, reports
and declarations required by any jurisdiction to which it is subject (unless and
only to the extent that the Company and each of its Subsidiaries has set aside
on its books provisions reasonably adequate for the payment of all unpaid and
unreported taxes) and has paid all taxes and other governmental assessments and
charges that are material in amount, shown or determined to be due on such
returns, reports and declarations, except those being contested in good faith
and has set aside on its books provision reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports
or declarations apply. There are no unpaid taxes in any material amount claimed
to be due by the taxing authority of any jurisdiction, and the officers of the
Company know of no basis for any such claim.

         (s) TRANSACTIONS WITH AFFILIATES. Except as set forth on Schedule 3(s)
and other than the grant or exercise of stock options disclosed on Schedule
3(c), none of the officers, directors, or employees of the Company is presently
a party to any transaction with the Company or any of its Subsidiaries (other
than for services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer, director, or any such employee has an interest or is an
officer, director, trustee or partner.

         (t) APPLICATION OF TAKEOVER PROTECTIONS. The Company and its board of
directors have taken or will take prior to the Commencement Date all necessary
action, if any, in order to render inapplicable any control share acquisition,
business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Certificate of
Incorporation or the laws of the state of its incorporation which is or could
become applicable to the Buyer as a result of the transactions contemplated by
this Agreement, including, without limitation, the Company's issuance of the
Securities and the Buyer's ownership of the Securities.

         (u) FOREIGN CORRUPT PRACTICES. Neither the Company, nor any of its
Subsidiaries, nor any director, officer, agent, employee or other person acting
on behalf of the Company or any of its Subsidiaries has, in the course of its
actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended; or made any unlawful bribe, rebate, payoff,
influence payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

         4. COVENANTS.

         (a) FILING OF REGISTRATION STATEMENT. The Company shall within five (5)
Trading Days from the date hereof file a new registration statement covering the
sale of the Commitment Shares and at least 2,500,000 Purchase Shares. The Buyer
and its counsel shall have a reasonable opportunity to review and comment upon
such registration statement or amendment to such registration statement and any
related prospectus prior to its filing with the SEC. The Company shall use its
best efforts to have such registration statement or amendment declared effective
by the SEC at the earliest possible date.

         (b) BLUE SKY. The Company shall, on or before the Commencement Date,
take such action, if any, as the Company shall reasonably determine is necessary
in order to obtain an exemption for or to

                                       12
<PAGE>   13

qualify the Commitment Shares and the Purchase Shares for sale to the Buyer
pursuant to this Agreement under applicable securities or "Blue Sky" laws of the
states of the United States, and shall provide evidence of any such action so
taken to the Buyer on or prior to the Commencement Date. The Company shall make
all filings and reports relating to the offer and sale of the Commitment Shares
and the Purchase Shares required under applicable securities or "Blue Sky" laws
of the states of the United States following the Commencement Date.

         (c) NO VARIABLE PRICED FINANCING. Other than pursuant to this
Agreement, the Company agrees that beginning on the date of this Agreement and
ending on the date of termination of this Agreement (as provided in Section
11(k) hereof), neither the Company nor any of its Subsidiaries shall, without
the prior written consent of the Buyer, contract for any equity financing
(including any debt financing with an equity component) or issue any equity
securities of the Company or any Subsidiary or securities convertible or
exchangeable into or for equity securities of the Company or any Subsidiary
(including debt securities with an equity component) which, in any case (i) are
convertible into or exchangeable for an indeterminate number of shares of common
stock, (ii) are convertible into or exchangeable for Common Stock at a price
which varies with the market price of the Common Stock, (iii) provide for any
"re-set" or adjustment of the purchase price, conversion rate or exercise price
after the issuance of the security, or (iv) contain any "make-whole" provision
based upon, directly or indirectly, the market price of the Common Stock after
the issuance of the security, in each case, other than reasonable and customary
anti-dilution adjustments for issuance of shares of Common Stock at a price
which is below the market price of the Common Stock.

         (d) LISTING. The Company shall promptly secure the listing of all of
the Purchase Shares and Commitment Shares upon each national securities exchange
and automated quotation system, if any, upon which shares of Common Stock are
then listed (subject to official notice of issuance) and shall maintain, so long
as any other shares of Common Stock shall be so listed, such listing of all such
securities from time to time issuable under the terms of the Transaction
Documents. The Company shall maintain the Common Stock's authorization for
quotation on the Principal Market. Neither the Company nor any of its
Subsidiaries shall take any action that would be reasonably expected to result
in the delisting or suspension of the Common Stock on the Principal Market. The
Company shall promptly, and in no event later than the following Trading Day,
provide to the Buyer copies of any notices it receives from the Principal Market
regarding the continued eligibility of the Common Stock for listing on such
automated quotation system or securities exchange. The Company shall pay all
fees and expenses in connection with satisfying its obligations under this
Section.

         (e) LIMITATION ON SHORT SALES AND HEDGING TRANSACTIONS. The Buyer
agrees that beginning on the date of this Agreement and ending on the date of
termination of this Agreement as provided in Section 11(k), the Buyer and its
agents, representatives and affiliates shall not in any manner whatsoever enter
into or effect, directly or indirectly, any (i) "short sale" (as such term is
defined in Rule 3b-3 of the 1934 Act) of the Common Stock or (ii) hedging
transaction, which establishes a net short position with respect to the Common
Stock; provided, however, that such restrictions shall not apply (i) if the
Buyer submits after a sale of shares of Common Stock a Purchase Notice entitling
the Buyer to receive a number of shares of Common Stock at least equal to the
number of shares so sold or (ii) if an Event of Default has occurred, including
any failure by the Company to timely issue any Purchase Shares required to be
issued pursuant to the terms of this Agreement.

         (f) LIMITATION ON SALES OF COMMITMENT SHARES. The Buyer agrees that the
Buyer shall not transfer or sell the Commitment Shares (as defined in Section
7(b) hereof) until the Maturity Date or until this Agreement has been
terminated, provided, however, that such restrictions shall not apply: (i) in
connection with any transfers to or among affiliates (as defined in the
Securities Exchange Act of 1934, as

                                       13
<PAGE>   14

amended), (ii) in connection with any pledge in connection with a bona fide loan
or margin account, or (iii) if an Event of Default has occurred, or any event
which, after notice and/or lapse of time, would become an Event of Default,
including any failure by the Company to timely issue Purchase Shares under this
Agreement. Notwithstanding the forgoing, the Buyer may transfer Commitment
Shares to a third party in order to settle a sale made by the Buyer where the
Buyer reasonably expects the Company to deliver Purchase Shares to the Buyer
under this Agreement so long as the Buyer maintains ownership of the same
overall number of shares of Common Stock by "replacing" the Commitment Shares so
transferred with Purchase Shares when the Purchase Shares are actually issued by
the Company to the Buyer.

         (h) DUE DILIGENCE. The Buyer shall have the right, from time to time as
the Buyer may reasonably deem appropriate, to perform reasonable due diligence
on the Company during normal business hours. The Company and its officers and
employees shall reasonably cooperate with the Buyer in connection with any
reasonable request by the Buyer related to the Buyer's due diligence of the
Company.

         (i) RESERVATION OF SHARES. The Company shall, so long as any Available
Amount is outstanding, reserve and keep available out of its authorized and
unissued Common Stock, solely for the purpose of effecting the purchase of the
Available Amount, such number of shares of Common Stock as shall from time to
time be sufficient to effect the purchase of the entire remaining Available
Amount, without regard to any restrictions or limitations on purchases.

         5. TRANSFER AGENT INSTRUCTIONS.

         All of the Purchase Shares and Commitment Shares to be issued under
this Agreement shall be issued without any restrictive legend and shall be
issued by the Company's transfer agent via The DTC Fast Automated Securities
Transfer Program, by crediting the appropriate number of shares of Common Stock
to which the Buyer shall be entitled to the Buyer's or its designee's balance
account with The DTC through The DTC DWAC system. The Company shall issue
irrevocable instructions to its transfer agent, and any subsequent transfer
agent, to issue Purchase Shares in the name of the Buyer or its respective
nominee(s), for the Purchase Shares (the "Irrevocable Transfer Agent
Instructions"). The Company warrants to the Buyer that no instruction other than
the Irrevocable Transfer Agent Instructions referred to in this Section 5, will
be given by the Company to its transfer agent with respect to the Purchase
Shares and that the Commitment Shares and the Purchase Shares shall otherwise be
freely transferable on the books and records of the Company as and to the extent
provided in this Agreement and the Registration Rights Agreement subject to the
provisions of Section 4(f) in the case of the Commitment Shares.

         6. CONDITIONS TO THE COMPANY'S OBLIGATION TO COMMENCE SALES OF SHARES
            OF COMMON STOCK.

         The obligation of the Company hereunder to commence sales of the
Purchase Shares is subject to the satisfaction of each of the following
conditions on or before the Commencement Date, provided that these conditions
are for the Company's sole benefit and may be waived by the Company at any time
in its sole discretion by providing the Buyer with prior written notice thereof:

which it is a party and delivered the same to the Company including the

<PAGE>   15

effective under the 1933 Act by the SEC and no stop order with respect to the
Registration Statement shall be pending or threatened by the SEC.

         (c) The representations and warranties of the Buyer shall be true and
correct in all material respects as of the date when made and as of the
Commencement Date as though made at that time (except for representations and
warranties that speak as of a specific date), and the Buyer shall have
performed, satisfied and complied in all material respects with the covenants,
agreements and conditions required by this Agreement to be performed, satisfied
or complied with by the Buyer at or prior to the Commencement Date.

         7. CONDITIONS TO THE BUYER'S OBLIGATION TO COMMENCE PURCHASES OF SHARES

                  (iii) In the event that the Commencement shall not have
         occurred on or before February 28, 2001, due to the failure to satisfy
         the conditions set forth in Sections 6 and 7 above with respect to the
         Commencement (and the nonbreaching party's failure to waive such
         unsatisfied condition(s)), the nonbreaching party shall have the option
         to terminate this Agreement at the close of business on such date or
         thereafter without liability of any party to any other party. If this

                                       23
<PAGE>   24

         Agreement is terminated pursuant to this Section 11(k)(iii) prior to
         the Commencement other than solely as a result of any material breach
         of the Buyer's obligation hereunder, the Company shall issue to the
         Buyer the Commitment Shares immediately upon the termination hereof.
         The number of Commitment Shares shall be appropriately adjusted for any
         reorganization, recapitalization, non-cash dividend, stock split or
         other similar transaction.

                  (iv) If by the Maturity Date, for any reason or for no reason
         the full Available Amount under this Agreement has not been purchased
         as provided for in Section 1 of this Agreement, by the Buyer without
         any liability or payment to the Company.

                  (v) At any time after the Commencement Date, and so long as
         the Company has provided appropriate notice as described below, if
         during any ten (10) consecutive Trading Days the Closing Sale Price of
         the Common Stock is below the Fixed Purchase Price for each of such ten
         (10) Trading Days, the Company shall have three (3) Trading Days to
         give written notice (a "Company Termination Notice") to the Buyer
         electing to terminate this Agreement without any liability or payment
         to the Buyer (a "Company Termination"). The Company Termination Notice
         shall not be effective until three (3) Trading Days after it has been
         received by the Buyer. Any Purchase Notices submitted by the Buyer
         which have a Purchase Date on or prior to the third (3rd) Trading Day
         after receipt by the Buyer of the Company Termination Notice, must be
         honored by the Company as otherwise provided herein. The Company may
         not deliver a Company Termination Notice or otherwise effect a Company
         Termination in anticipation of or in connection with a Major
         Transaction until such Major Transaction (whether or not consummated)
         has been publicly disclosed for a period of at least sixty (60) Trading
         Days. In the event that within sixty (60) Trading Days of a Company
         Termination, the Company publicly discloses that a Major Transaction
         has been consummated or may be consummated, the Buyer shall be entitled
         to the following payment equal to the Purchase Rate (determined as of
         the date of the Company Termination Notice assuming a Purchase Amount
         equal to the remaining Available Amount) multiplied by the amount, if
         any that (A) the arithmetic average of the Closing Sale Price for the
         Common Stock for the ten (10) Trading Days following either: (1) the
         public disclosure of the Major Transaction or (2) the consummation of
         the Major Transaction, as selected by the Buyer, exceeds (B) the
         Purchase Price determined as of the date the Company Termination is
         effected. Any payments under the previous sentence shall be made either
         in the form of cash or registered, freely tradable shares of Common
         Stock, eleven (11) Trading Days following either: (1) the public
         disclosure of the Major Transaction or (2) the consummation of the
         Major Transaction, as selected by the Buyer. To the extent that such
         payment has not been paid by the fifth (5th) Trading Date after its due
         date, the Buyer shall be entitled to interest in an amount equal to one
         percent (1.0%) of the unpaid amount per day, payable on demand. If paid
         in shares of Common Stock, the "dollar value" per share of Common Stock
         shall be the average of the Closing Bid Prices of the Common Stock for
         the five (5) consecutive Trading Days prior to the payment date.

                  (vi) This Agreement shall automatically terminate on the date
         that the Company sells and the Buyer purchases Six Million Dollars
         ($6,000,000) of Common Stock as provided herein, without any action or
         notice on the part of any party.

Except as set forth in Sections 11(k)(i) and 11(k)(vi), any termination of this
Agreement pursuant to this Section 11(k) shall be effected by written notice
from the Company to the Buyer, or the Buyer to the Company, as the case may be,
setting forth the basis for the termination hereof. The representations and
warranties of the Company and the Buyer contained in Sections 2 and 3 hereof,
the indemnification provisions set forth in Section 8 hereof and the agreements
and covenants set forth in Section 1(g) and 11,

                                       24
<PAGE>   25
shall survive the Commencement and any termination of this Agreement. No
termination of this Agreement shall effect the Company's or the Buyer's
obligations under this Agreement with respect to pending purchases and the
Company and the Buyer shall complete their respective obligations with respect
to any pending purchases under this Agreement.

         (l) NO FINANCIAL ADVISOR, PLACEMENT AGENT, BROKER OR FINDER. The
Company represents and warrants to the Buyer that it has not engaged any
financial advisor, placement agent, broker or finder in connection with the
transactions contemplated hereby. The Buyer represents and warrants to the
Company that it has not engaged any financial advisor, placement agent, broker
or finder in connection with the transactions contemplated hereby. The Company
shall be responsible for the payment of any fees or commissions, if any, of any
financial advisor, placement agent, broker or finder relating to or arising out
of the transactions contemplated hereby. The Company shall pay, and hold the
Buyer harmless against, any liability, loss or expense (including, without
limitation, attorneys' fees and out of pocket expenses) arising in connection
with any such claim.

         (m) NO STRICT CONSTRUCTION. The language used in this Agreement will be
deemed to be the language chosen by the parties to express their mutual intent,
and no rules of strict construction will be applied against any party.

         (n) REMEDIES, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The
Buyer's remedies provided in this Agreement shall be cumulative and in addition
to all other remedies available to the Buyer under this Agreement, at law or in
equity (including a decree of specific performance and/or other injunctive
relief), no remedy of the Buyer contained herein shall be deemed a waiver of
compliance with the provisions giving rise to such remedy and nothing herein
shall limit the Buyer's right to pursue actual damages for any failure by the
Company to comply with the terms of this Agreement. The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to
the Buyer and that the remedy at law for any such breach may be inadequate. The
Company therefore agrees that, in the event of any such breach or threatened
breach, the Buyer shall be entitled, in addition to all other available
remedies, to an injunction restraining any breach, without the necessity of
showing economic loss and without any bond or other security being required.

         (o) CHANGES TO THE TERMS OF THIS AGREEMENT. This Agreement and any
provision hereof may only be amended by an instrument in writing signed by the
Company and the Buyer. The term "Agreement" and all reference thereto, as used
throughout this instrument, shall mean this instrument as originally executed,
or if later amended or supplemented, then as so amended or supplemented.

         (p) ENFORCEMENT COSTS. If: (i) this Agreement is placed by the Buyer in
the hands of an attorney for enforcement or is enforced by the Buyer through any
legal proceeding; or (ii) an attorney is retained to represent the Buyer in any
bankruptcy, reorganization, receivership or other proceedings affecting
creditors' rights and involving a claim under this Agreement; or (iii) an
attorney is retained to represent the Buyer in any other proceedings whatsoever
in connection with this Agreement, then the Company shall pay to the Buyer, as
incurred by the Buyer, all reasonable costs and expenses including attorneys'
fees incurred in connection therewith, in addition to all other amounts due
hereunder.

         (q) FAILURE OR INDULGENCE NOT WAIVER. No failure or delay in the
exercise of any power, right or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other right,
power or privilege.

                         FORM OF COMPANY COUNSEL OPINION

         Capitalized terms used herein but not defined herein, have the meaning
set forth in the Common Stock Purchase Agreement. Based on the foregoing, and
subject to the assumptions and qualifications set forth herein, we are of the
opinion that:

1.   The Company is a corporation existing and in good standing under the laws
     of the State of Nevada.

2.   The Company has the corporate power to execute and deliver, and perform its
     obligations under, each Transaction Document to which it is a party. The
     Company has the corporate power to conduct its business as, to the best of
     our knowledge, it is now conducted, and to own and use the properties owned
     and used by it.

3.   The execution, delivery and performance by the Company of the Transaction
     Documents to which it is a party have been duly authorized by all necessary
     corporate action on the part of the Company. The execution and delivery of
     the Transaction Documents by the Company, the performance of the
     obligations of the Company thereunder and the consummation by it of the
     transactions contemplated therein have been duly authorized and approved by
     the Company's Board of Directors and no further consent, approval or
     authorization of the Company, its Board of Directors or its stockholders is
     required. The Transaction Documents to which the Company is a party have
     been duly executed and delivered by the Company and are the valid and
     binding obligations of the Company, enforceable against the Company in
     accordance with their terms except as such enforceability may be limited by
     general principals of equity or applicable bankruptcy, insolvency,
     liquidation or similar laws relating to, or affecting creditor's rights and
     remedies.

4.   The issuance and sale of the Commitment Shares and the Purchase Shares
     pursuant to the terms and conditions of the Common Stock Purchase Agreement
     has been duly authorized. ______ shares of Common Stock have been properly
     reserved for issuance as Purchase Shares in accordance with the Common
     Stock Purchase Agreement. The Commitment Shares have been issued in
     accordance with the Common Stock Purchase Agreement and are validly issued,
     fully paid and non-assessable and free of all taxes, liens, charges,
     restrictions, rights of first refusal and preemptive rights. When issued
     and paid for in accordance with the Common Stock Purchase Agreement, the
     Purchase Shares shall be validly issued, fully paid and non-assessable and
     free of all taxes, liens, charges, restrictions, rights of first refusal
     and preemptive rights. To our knowledge, the execution and delivery of the
     Registration Rights Agreement do not, and the performance by the Company of
     its obligations thereunder shall not, give rise to any rights of any other
     person for the registration under the Securities Act of any shares of
     Common Stock or other securities of the Company which have not been waived.

5.   The execution, delivery and performance by the Company of the Transaction
     Documents, the consummation by the Company of the transactions contemplated
     thereby including the offering, sale and issuance of the Commitment Shares
     and the Purchase Shares in accordance with the terms and conditions of the
     Common Stock Purchase Agreement, and fulfillment and compliance with terms
     of the Transaction Documents, does not and shall not: (i) conflict with,
     constitute a breach of or default (or an event which, with the giving of
     notice or lapse of time or both, constitutes or could constitute a breach
     or a default), under (a) the Certificate of Incorporation or the Bylaws of
     the Company, (b) any material agreement, note, lease, mortgage, deed or
     other material instrument to which to our knowledge

<PAGE>   33

     the Company is a party or by which the Company or any of its assets are
     bound, (ii) result in any violation of any statute, law, rule or regulation
     applicable to the Company, or (iii) to our knowledge, violate any order,
     writ, injunction or decree applicable to the Company or any of its
     subsidiaries.

6.   As of the date hereof, the authorized capital stock of the Company consists
     of (i) ___________ shares of Common Stock, par value $_____ per share, of
     which to our knowledge ___________ shares are issued and outstanding, and
     (ii) ________ shares of preferred stock, par value $_____ per share of
     which to our knowledge ________ shares are issued and outstanding. Except
     as set forth on Schedule 3(c) of the Common Stock Purchase Agreement, to
     our knowledge, there are no outstanding shares of capital stock or other
     securities convertible into or exchangeable or exercisable for shares of
     the capital stock of the Company.

7.   The Common Stock is registered pursuant to Section 12(g) of the Exchange
     Act. To our knowledge, since January 1, 1999, the Company has been in
     compliance with the reporting requirements of the Exchange Act applicable
     to it. To our knowledge, since January 1, 1999, the Company has not
     received any written notice from the Principal Market stating that the
     Company has not been in compliance with any of the rules and regulations
     (including the requirements for continued listing) of the Principal Market.

8.   Other then which has been obtained and completed prior to the date hereof,
     no authorization, approval, consent, filing or other order of any federal
     or state governmental body, regulatory agency, self-regulatory organization
     or stock exchange or market, or the shareholders of the Company, or any
     court, or, to our knowledge, any third party, is required to be obtained by
     the Company to enter into and perform its obligations under the Transaction
     Documents or for the issuance and sale of the Commitment Shares or the
     Purchase Shares as contemplated by the Transaction Documents.

         We further advise you that to our knowledge, except as disclosed on
Schedule 3(h) in the Common Stock Purchase Agreement, there is no action, suit,
proceeding, inquiry or investigation before or by any court, public board or
body, any governmental agency, any stock exchange or market, or self-regulatory
organization, which has been threatened in writing or which is currently pending
against the Company, any of its subsidiaries, any officers or directors of the
Company or any of its subsidiaries or any of the properties of the Company or
any of its subsidiaries.

         In addition, we have participated in the preparation of the
Registration Statement (SEC File #________) covering the sale of the Purchase
Shares and the Commitment Shares including the prospectus dated ____________,
contained therein and in conferences with officers and other representatives of
the Company (including the Company's independent auditors) during which the
contents of the Registration Statement and related matters were discussed and
reviewed and, although we are not passing upon and do not assume any
responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement, on the basis of the information that
was developed in the course of the performance of the services referred to
above, considered in the light of our understanding of the applicable law,
nothing came to our attention that caused us to believe that the Registration
Statement (other than the financial statements and schedules and the other
financial and statistical data included therein, as to which we express no
belief), as of their dates, contained any untrue statement of a material fact or
omitted to state any material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

($6,000,000) of the Company's common stock, par value $.0001 per share (the
"COMMON STOCK"). The shares of Common Stock to be purchased thereunder are
referred to herein as, the "PURCHASE SHARES." This letter shall serve as our

Buyer from time to time upon surrender to you of a properly completed and duly
executed Purchase Notice, in the form attached hereto as Exhibit I, and a
Company Confirmation of Purchase Notice, in the form attached hereto as Exhibit

         Specifically, upon receipt by the Company of a copy of a Purchase

of Purchase Notice, you shall use your best efforts to, within one (1) Trading
Day following the date of receipt of the Company Confirmation of Purchase
Notice, (A) issue and surrender to a common carrier for overnight delivery to
the address as specified in the Purchase Notice, a certificate, registered in
the name of the Buyer or its designee, for the number of shares of Common Stock
to which the Buyer shall be entitled as set forth in the Company Confirmation of

Company ("DTC") Fast Automated Securities Transfer Program, upon the request of
the Buyer, credit such aggregate number of shares of Common Stock to which the
Buyer shall be entitled to the Buyer's or its designee's balance account with
DTC through its Deposit Withdrawal At Custodian ("DWAC") system provided the
Buyer causes its bank or broker to initiate the DWAC transaction. ("TRADING DAY"
shall mean any day on which the Nasdaq Market is open for customary trading.)

         The Company hereby confirms to you and the Buyer that certificates
representing the Purchase Shares shall not bear any legend restricting transfer
of the Purchase Shares thereby and should not be subject to any stop-transfer
restrictions and shall otherwise be freely transferable on the books and records
of the Company provided that the Company counsel delivers the Notice of
Effectiveness set forth in Exhibit III

<PAGE>   39

attached hereto, and that if the Purchase Shares are not registered for sale
under the Securities Act of 1933, as amended, then the certificates for the
Purchase Shares shall bear the following legend:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE
         STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT
         AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE
         ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
         THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES

         The Company hereby confirms to you and the Buyer that no instructions
other than as contemplated herein will be given to you by the Company with
respect to the Purchase Shares.

         Please be advised that the Buyer is relying upon this letter as an
inducement to purchase shares of Common Stock under the Common Stock Purchase
Agreement and, accordingly, the Buyer is a third party beneficiary to these
instructions.

"COMPANY"), and have represented the Company in connection with that certain
Common Stock Purchase Agreement (the "COMMON STOCK PURCHASE AGREEMENT") entered
into by and among the Company and FUSION CAPITAL FUND II, LLC (the "BUYER")
pursuant to which (i) the Company may sell to the Buyer up to Six Million
Dollars ($6,000,000) of the Company's common stock, par value $.0001 per share
(the "COMMON STOCK" and the shares of Common Stock to be purchased thereunder
are referred to herein as, the "PURCHASE Shares"), and (ii) the Company has
agreed to issue to the Buyer 200,000 shares of Common Stock (the "COMMITMENT
Shares"). Pursuant to the Common Stock Purchase Agreement, the Company also has
entered into a Registration Rights Agreement with the Buyer (the "REGISTRATION
RIGHTS AGREEMENT") pursuant to which the Company agreed, among other things, to
register the Purchase Shares and the Commitment Shares under the Securities Act
of 1933, as amended (the "1933 ACT"). In connection with the Company's
obligations under the Common Stock Purchase Agreement and the Registration
Rights Agreement, on _____________, the Company filed a Registration Statement
(File No. 333-_____________) (the "REGISTRATION STATEMENT") with the Securities
and Exchange Commission (the "SEC") relating to the sale of the Purchase Shares
and the Commitment Shares.

          In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Purchase Shares
and the Commitment Shares are available for sale under the 1933 Act pursuant to
the Registration Statement.

          The Buyer has confirmed it shall comply with all securities laws and
regulations applicable to it including applicable prospectus delivery
requirements upon sale of the Commitment Shares or the Purchase Shares.

                                   Very truly yours,

warrants to the Banks and the Administrative Agent that:

         6.3 GOVERNING LAW. THIS AMENDMENT SHALL BE A CONTRACT MADE UNDER AND
GOVERNED BY THE LAWS OF THE STATE OF ILLINOIS, WITHOUT REGARD TO CONFLICT OF
LAWS PRINCIPLES. Wherever possible each provision of this Amendment shall be
interpreted in such manner as to be effective and valid under applicable laws,

counterparts, and by the parties hereto on the same or separate counterparts,

<PAGE>   12

Agreement shall remain in full force and effect and is hereby ratified in all
respects. On and after the effectiveness of the amendment to the Existing Credit
Agreement accomplished hereby, each reference in the Amended Credit Agreement to
"this Agreement," "hereunder," "hereof," "herein" or words of like import, and
each reference to the Existing Credit Agreement in any Note and in any other
agreement, document or other instrument executed and delivered pursuant to the
Amended Credit Agreement, shall mean and be a reference to the Amended Credit
Agreement.

         6.6 SUCCESSORS AND ASSIGNS. This Amendment shall be binding upon the
parties hereto and their respective successors and assigns, and shall inure to
the sole benefit of the parties hereto and the successors and assigns of the

the provisions of Section 10.6.7 of the "Existing Credit Agreement" (as defined
therein) for the Fiscal Quarter ending March 31, 2001. The Company acknowledges
that Section 10.6.7 has been amended pursuant to this Amendment, that the prior
waiver did not constitute a waiver of such Section as so amended and that,
accordingly, the Company shall be required to comply with Section 10.6.7 of the
Amended Credit Agreement for the Fiscal Quarter ending March 31, 2001.

         6.8 FLOOR ON EURODOLLAR MARGIN. The parties hereto agree that,
notwithstanding any other provision hereof or of the Amended Credit Agreement,

determined in accordance with the Existing Credit Agreement.

         6.9 ADDITIONAL AMENDMENT FEE. In consideration of the execution and
delivery hereof by the Required Banks, the Company agrees to pay the Agent, for
the account of the Banks pro rata according to the respective Revolving
Percentages, an additional amendment fee of $600,000 on September 15, 2001;
provided that the Company shall be relieved of its obligation to pay 50% of such
additional amendment fee if, on or prior to September 15, 2001, the Company
shall have repaid in full all of its obligations under the Credit Agreement
(including the other 50% of such additional amendment fee), canceled all Letters
of Credit and terminated the Commitments.

         Delivered at Chicago, Illinois, as of the day and year first above
