         WHEREAS, the Company wishes to issue an option to the Purchaser in the
form of Exhibit B hereto (as amended, modified and/or supplemented from time to
time, the "Option") to purchase up to 650,000 shares of the Company's Common

         3. Closing, Delivery and Payment.

                  3.1 Closing. Subject to the terms and conditions herein, the

represents and warrants to the Purchaser as follows:

                  4.1 Organization, Good Standing and Qualification. The Company
is a corporation duly organized, validly existing and in good standing under the
laws of the State of Michigan. The Company has the corporate power and authority
to own and operate its properties and assets and, insofar as it is or shall be a
party thereto, to (1) execute and deliver (i) this Agreement, (ii) the Note and
the Option to be issued in connection with this Agreement, (iii) the Master
Security Agreement dated as of the date hereof between the Company, certain

                                       2
<PAGE>

Subsidiaries of the Company and the Purchaser (as amended, modified or
supplemented from time to time, the "Master Security Agreement"), (iv) the
Registration Rights Agreement relating to the Securities dated as of the date
hereof between the Company and the Purchaser (as amended, modified or

all other documents, instruments and agreements entered into in connection with

Note and the shares of Common Stock issuable upon conversion of the Note (the

is authorized to do business and is in good standing as a foreign corporation in
all jurisdictions in which the nature or location of its activities and of its
properties (both owned and leased) makes such qualification necessary, except
for those jurisdictions in which failure to do so has not, or could not
reasonably be expected to have, individually or in the aggregate, a material
adverse effect on the business, assets, liabilities, condition (financial or
otherwise), properties or operations of the Company (a "Material Adverse
Effect").

                  4.2 Subsidiaries. The Company does not have any Subsidiaries.
For the purpose of this Agreement, a "Subsidiary" of any person or entity means
(i) a corporation or other entity whose shares of stock or other ownership
interests having ordinary voting power (other than stock or other ownership
interests having such power only by reason of the happening of a contingency) to
elect a majority of the directors of such corporation, or other persons or
entities performing similar functions for such person or entity, are owned,
directly or indirectly, by such person or entity or (ii) a corporation or other
entity in which such person or entity owns, directly or indirectly, more than
50% of the equity interests at such time.

                  4.3      Capitalization; Voting Rights.

                  (a) The authorized capital stock of the Company, as of the
         date hereof consists of 9,990,575 shares, of which 9,785,575 are shares
         of Common Stock, no par value, 3,774,346 shares of which are issued and
         outstanding, and 205,000 are shares of preferred stock, no par value of
         which no shares of preferred stock are issued and outstanding.

                  (b) Other than: (i) the shares reserved for issuance under the
         Company's stock option plans; and (ii) shares which may be granted
         pursuant to this Agreement and the Related Agreements, there are no
         outstanding options, warrants, rights (including conversion or
         preemptive rights and rights of first refusal), proxy or stockholder
         agreements, or arrangements or agreements of any kind for the purchase
         or acquisition from the Company of any of its securities. Neither the
         offer, issuance or sale of any of the Note or the Option, or the
         issuance of any of the Note Shares or Option Shares, nor the
         consummation of any transaction contemplated hereby will result in a
         change in the price or number of any securities of the Company
         outstanding, under anti-dilution or other similar provisions contained
         in or affecting any such securities.

                  (c) To the knowledge of the Company, all issued and
         outstanding shares of the Company's Common Stock: (i) have been duly
         authorized and validly issued and are

                                       3
<PAGE>

         fully paid and nonassessable; and (ii) were issued in compliance with
         all applicable state and federal laws concerning the issuance of
         securities. For purposes of this Agreement, "knowledge of the Company"
         and all derivatives thereof, shall mean the actual knowledge, after due
         inquiry of each of Kenneth Rieth and/or Peter Canepa existing on the
         date hereof.

                  (d) The rights, preferences, privileges and restrictions of
         the shares of the Common Stock are as stated in the Company's
         Certificate of Incorporation, as amended (the "Charter"). The Note
         Shares and Option Shares have been duly and validly reserved for
         issuance. When issued in compliance with the provisions of this
         Agreement and the Company's Charter, the Securities will be validly
         issued, fully paid and nonassessable, and will be free of any liens or
         encumbrances; provided, however, that the Securities may be subject to
         restrictions on transfer under state and/or federal securities laws as
         set forth herein or as otherwise required by such laws at the time a
         transfer is proposed.

                  4.4 Authorization; Binding Obligations. All corporate action
on the part of the Company (including its officers and directors) necessary for
the authorization of this Agreement and the Related Agreements, the performance
of all obligations of the Company hereunder and under the other Related
Agreements at the Closing and, the authorization, sale, issuance and delivery of
the Note and the Option has been taken or will be taken prior to the Closing.
This Agreement and the Related Agreements, when executed and delivered and to
the extent it is a party thereto, will be valid and binding obligations of each
of the Company, enforceable against each such entity in accordance with their
terms, except:

                  (a) as limited by applicable bankruptcy, insolvency,
         reorganization, moratorium or other laws of general application
         affecting enforcement of creditors' rights; and

                  (b) general principles of equity that restrict the
         availability of equitable or legal remedies.

         The sale of the Note and the subsequent conversion of the Note into
Note Shares are not and will not be subject to any preemptive rights or rights
of first refusal that have not been properly waived or complied with. The
issuance of the Option and the subsequent exercise of the Option for Option
Shares are not and will not be subject to any preemptive rights or rights of
first refusal that have not been properly waived or complied with.

                  4.5      Controls and Procedures.

                  (a) The Company has established and maintains "disclosure
         controls and procedures" (as defined in Rules 13a-15(f) and 15d-16(e)
         of the Securities Exchange Act of 1934, as amended (the "Exchange
         Act")); the Company's "disclosure controls and procedures" are
         reasonably designed to ensure that all information (both financial and
         non-financial) required to be disclosed by the Company in the reports
         that it files or submits under the Exchange Act is recorded, processed,
         summarized and reported within the time periods specified in the Rules
         and Regulations, and that all such information is accumulated and
         communicated to the Company's management as appropriate to allow

                                       4
<PAGE>

         timely decisions regarding required disclosure and to make the
         certifications of the Chief Executive Officer and Chief Financial
         Officer of the Company required under the Exchange Act with respect to
         such reports.

                  (b) Since February 28, 2005 (the "Balance Sheet Date"), the
         Company's auditors and the audit committee of the Board of Directors of
         the Company (or persons fulfilling the equivalent function) have not
         been advised of (i) any significant deficiencies in the design or
         operation of internal controls which could adversely affect the
         Company's ability to record, process, summarize and report financial
         data nor any material weaknesses in internal controls; (ii) any fraud,
         whether or not material, that involves management or other employees
         who have a significant role in the Company's internal controls.

                  4.6 Obligations to Related Parties. No relationship, direct or
indirect, exists between or among any of the Company or any affiliate of the
Company, on the one hand, and any director, officer, stockholder, customer or
supplier of the Company or any affiliate of the Company, on the other hand,
which is required by the Securities Act, the Exchange Act or the Rules and
Regulations to be described in any SEC Report which is not so described and
described as required. There are no outstanding loans, advances (except normal
advances for business expenses in the ordinary course of business) or guarantees
of indebtedness by the Company to or for the benefit of any of the officers or
directors of the Company or any of their respective family members, except as
disclosed in the SEC Reports. The Company has not, in violation of the
Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), directly or indirectly,
extended or maintained credit, arranged for the extension of credit, or renewed
an extension of credit, in the form of a personal loan to or for any director or
executive officer of the Company.

                  4.7 Changes. Since the Balance Sheet Date, there has not been:

                  (a)      any Material Adverse Effect;

                  (b) any resignation or termination of any officer, key
         employee or group of employees of the Company;

                  (c) any material change, except in the ordinary course of
         business, in the contingent obligations of the Company by way of
         guaranty, endorsement, indemnity, warranty or otherwise;

                  (d) any damage, destruction or loss, whether or not covered by
         insurance, which has had a Material Adverse Effect;

                  (e) any waiver by the Company of a valuable right or of a
         material debt owed to it;

                  (f) any direct or indirect material loans made by the Company
         to any stockholder, employee, officer or director of the Company, other
         than advances made in the ordinary course of business;

                                       5

         distribution of the assets of the Company;

                  (i) any labor organization activity related to the Company;

                  (j) any debt, obligation or liability incurred, assumed or
         guaranteed by the Company, except those for immaterial amounts and for
         current liabilities incurred in the ordinary course of business;

                  (k) any sale, assignment or transfer of any patents,
         trademarks, copyrights, trade secrets or other intangible assets owned
         by the Company;

                  (l) any change in any material agreement to which the Company
         is a party or by which either the Company is bound which has had a
         Material Adverse Effect;

                  (m) any other event or condition of any character that has had
         a Material Adverse Effect; or

                  (n) any arrangement or commitment by the Company to do any of
         the acts described in subsection (a) through (m) above.

                  4.8 Title to Properties and Assets; Liens, Etc. The Company
has good and marketable title to its properties and assets, and good title to

         business, so long as they have no effect on the lien priority of the

violation, or be in conflict with or constitute a default under any such term or
provision, or result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Company or the suspension,

be employed by, or to contract with, the Company because of the nature of the
business to be conducted by the Company; and to the Company's knowledge the
continued employment by the Company of its present employees, and the
performance of the Company's contracts with its independent contractors, will
not result in any such violation. The Company is not aware that any of its

their duties to the Company. The Company has not received any notice alleging

a timely manner. The Company has all material franchises, permits, licenses and
any similar authority necessary for the conduct of its business as now being
conducted by it, the lack of which has had a Material Adverse Effect.

proceeding for any such purpose.

                  6.2 Listing. The Company shall promptly secure the listing of
the shares of Common Stock issuable upon conversion of the Note and upon the
exercise of the Option on the Principal Market upon which shares of Common Stock
are listed (subject to official notice of issuance) and shall maintain such
listing so long as any other shares of Common Stock shall be so listed. The
Company will maintain the listing of its Common Stock on the Principal Market,
and will comply in all material respects with the Company's reporting, filing
and other obligations under the bylaws or rules of the National Association of
Securities Dealers ("NASD") and such exchanges, as applicable.

                  6.3 Market Regulations. The Company shall notify the SEC, NASD
and applicable state authorities, in accordance with their requirements, of the
transactions contemplated by this Agreement, and shall take all other necessary
action and proceedings as may be required and permitted by applicable law, rule
and regulation, for the legal and valid issuance of the Securities to the
Purchaser and promptly provide copies thereof to the Purchaser.

                  6.4 Reporting Requirements. The Company shall timely file with
the SEC all reports required to be filed pursuant to the Exchange Act and

purposes only and to pay its senior secured debt to Comerica Bank and
subordinated debt to The Hillstreet Fund II, L.P. in full, in the amounts set
forth in the Company's Disbursement Letter.

                  6.6 Access to Facilities. Company will permit any
representatives designated by Laurus (or any successor of Laurus), upon
reasonable notice and during normal business hours, at such person's expense and
accompanied by a representative of Company, to:

                  (a) have access to, visit, inspect, review, evaluate and make
         physical verification and appraisals of Company's properties and the
         Collateral;

                  (b) inspect, audit and copy (or take originals if necessary)
         and make extracts from Company's Books and Records, including
         management letters prepared by independent accountants; and

                  (c) discuss with Company's principal officers, and independent
         accountants, Company's business, assets, liabilities, financial
         condition, results of operations and business prospects.

Company will deliver to Laurus any instrument necessary for Laurus to obtain
records from any service bureau maintaining records for Company. If any
internally prepared financial information, including that required under this
Section is unsatisfactory in any manner to Laurus, Laurus may request that the
Accountants review the same. Laurus acknowledges that it may be provided
material, non-public information and acknowledges its continuing obligations
under

                                       15

                  6.7 Taxes. Each of the Company and each of its Subsidiaries
will promptly pay and discharge, or cause to be paid and discharged, when due
and payable, all taxes, assessments and governmental charges or levies imposed
upon the income, profits, property or business of the Company and its
Subsidiaries; provided, however, that any such tax, assessment, charge or levy
need not be paid currently if the validity thereof shall currently and
diligently be contested in good faith by appropriate proceedings, such tax,
assessment, charge or levy shall have no effect on the lien priority of the
Purchaser in any property of the Company or any of its Subsidiaries and if the
Company and/or such Subsidiary shall have set aside on its books adequate
reserves with respect thereto in accordance with GAAP, and provided, further,
that the Company and its Subsidiaries will pay all such taxes, assessments,
charges or levies forthwith upon the commencement of proceedings to foreclose
any lien which may have attached as security therefor.

                  6.8 Insurance. Each of the Company and its Subsidiaries will
keep its assets which are of an insurable character insured by financially sound
and reputable insurers against loss or damage by fire, explosion and other risks
customarily insured against by companies in similar business similarly situated
as the Company and its Subsidiaries; and the Company and its Subsidiaries will
maintain, with financially sound and reputable insurers, insurance against other
hazards and risks and liability to persons and property to the extent and in the
manner which the Company reasonably believes is customary for companies in
similar business similarly situated as the Company and its Subsidiaries and to
the extent available on commercially reasonable terms. The Company, and each of
its Subsidiaries, will jointly and severally bear the full risk of loss from any
loss of any nature whatsoever with respect to the assets pledged to the
Purchaser as security for their respective obligations hereunder and under the
Related Agreements. At the Company's and each of its Subsidiaries' joint and
several cost and expense in amounts and with carriers reasonably acceptable to
the Purchaser, each of the Company and each of its Subsidiaries shall (i) keep
all its insurable properties and properties in which it has an interest insured
against the hazards of fire, flood, sprinkler leakage, those hazards covered by
extended coverage insurance and such other hazards, and for such amounts, as is
customary in the case of companies engaged in businesses similar to the
Company's or the respective Subsidiary's including business interruption
insurance; (ii) maintain a bond in such amounts as is customary in the case of
companies engaged in businesses similar to the Company's or the respective
Subsidiary's insuring against larceny, embezzlement or other criminal
misappropriation of insured's officers and employees who may either singly or
jointly with others at any time have access to the assets or funds of the
Company or any of its Subsidiaries either directly or through governmental
authority to draw upon such funds or to direct generally the disposition of such
assets; (iii) maintain public and product liability insurance against claims for
personal injury, death or property damage suffered by others; (iv) maintain all
such worker's compensation or similar insurance as may be required under the
laws of any state or jurisdiction in which the Company or the respective
Subsidiary is engaged in business; and (v) furnish the Purchaser with (x) copies
of all policies and evidence of the maintenance of such policies at least thirty
(30) days before any expiration date, (y) excepting the Company's workers'
compensation policy, endorsements to such policies naming the Purchaser as
"co-insured" or "additional insured" and appropriate loss payable endorsements
in form and substance satisfactory to the Purchaser,

                                       16
<PAGE>

naming the Purchaser as loss payee, and (z) evidence that as to the Purchaser
the insurance coverage shall not be impaired or invalidated by any act or
neglect of the Company or any Subsidiary and the insurer will provide the
Purchaser with at least thirty (30) days notice prior to cancellation. The
Company and each Subsidiary shall instruct the insurance carriers that in the
event of any loss thereunder, the carriers shall make payment for such loss to
the Company and/or the Subsidiary and the Purchaser jointly. In the event that
as of the date of receipt of each loss recovery upon any such insurance, the
Purchaser has not declared an event of default with respect to this Agreement or
any of the Related Agreements, then the Company and/or such Subsidiary shall be
permitted to direct the application of such loss recovery proceeds toward
investment in property, plant and equipment that would comprise "Collateral"
secured by the Purchaser's security interest pursuant to the Master Security
Agreement or such other security agreement as shall be required by the
Purchaser, with any surplus funds to be applied toward payment of the
obligations of the Company to the Purchaser. In the event that the Purchaser has
properly declared an event of default with respect to this Agreement or any of
the Related Agreements, then all loss recoveries received by the Purchaser upon
any such insurance thereafter may be applied to the obligations of the Company
hereunder and under the Related Agreements, in such order as the Purchaser may
determine. Any surplus (following satisfaction of all Company obligations to the
Purchaser) shall be paid by the Purchaser to the Company or applied as may be
otherwise required by law. Any deficiency thereon shall be paid by the Company
or the Subsidiary, as applicable, to the Purchaser, on demand.

                  6.9 Intellectual Property. Each of the Company and each of its
Subsidiaries shall maintain in full force and effect its existence, rights and
franchises and all licenses and other rights to use Intellectual Property owned
or possessed by it and reasonably deemed to be necessary to the conduct of its
business.

                  6.10 Properties. Each of the Company and each of its
Subsidiaries will keep its properties in good repair, working order and
condition, reasonable wear and tear excepted, and from time to time make all
needful and proper repairs, renewals, replacements, additions and improvements
thereto; and each of the Company and each of its Subsidiaries will at all times
comply with each provision of all leases to which it is a party or under which
it occupies property if the breach of such provision could, either individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.

                  6.11 Confidentiality. The Company will not, and will not
permit any of its Subsidiaries to, disclose, and will not include in any public
announcement, the name of the Purchaser, unless expressly agreed to by the
Purchaser or unless and until such disclosure is required by law or applicable
regulation, and then only to the extent of such requirement. Notwithstanding the
foregoing, the Company may disclose the Purchaser's identity and the terms of
this Agreement to its current and prospective debt and equity financing sources.

                  6.12 Required Approvals. For so long as twenty-five percent
(25%) of the principal amount of the Note is outstanding, the Company, without
the prior written consent of the Purchaser, shall not, and shall not permit any

         of amendment to or modification of) any agreement or instrument which

The Company agrees to cooperate with the Purchaser in connection with all
resales pursuant to Rule 144(d) and Rule 144(k) and provide legal opinions
necessary to allow such resales provided the Company and its counsel receive
reasonably requested representations from the Purchaser and broker, if any.

                  6.14 Opinion. On the Closing Date, the Company will deliver to
the Purchaser an opinion acceptable to the Purchaser from the Company's external

                  6.15 Margin Stock. The Company will not permit any of the

                  6.16     Financing Right of First Refusal.

         first refusal to provide any Additional Financing (as defined below) to
         be issued by the Company and/or any of its Subsidiaries, subject to the
         following terms and conditions. From and after the date hereof, prior
         to the incurrence of any additional indebtedness convertible into
         Common Stock and/or the sale or issuance of any convertible equity
         interests of the

                                       19
<PAGE>

         Company or any of its Subsidiaries (an "Additional Financing"), the
         Company and/or any Subsidiary of the Company, as the case may be, shall
         notify the Purchaser of its intention to enter into such Additional
         Financing. In connection therewith, the Company and/or the applicable
         Subsidiary thereof shall submit a fully executed term sheet (a
         "Proposed Term Sheet") to the Purchaser setting forth the terms,
         conditions and pricing of any such Additional Financing (such financing
         to be negotiated on "arm's length" terms and the terms thereof to be
         negotiated in good faith) proposed to be entered into by the Company
         and/or such Subsidiary. The Purchaser shall have the right, but not the
         obligation, to deliver its own proposed term sheet (the "Purchaser Term
         Sheet") setting forth the terms and conditions upon which the Purchaser
         would be willing to provide such Additional Financing to the Company
         and/or such Subsidiary. The Purchaser Term Sheet shall contain terms no
         less favorable to the Company and/or such Subsidiary than those
         outlined in Proposed Term Sheet. The Purchaser shall deliver such
         Purchaser Term Sheet within ten business days of receipt of each such
         Proposed Term Sheet. If the provisions of the Purchaser Term Sheet are
         at least as favorable to the Company and/or such Subsidiary, as the
         case may be, as the provisions of the Proposed Term Sheet, the Company
         and/or such Subsidiary shall enter into and consummate the Additional
         Financing transaction outlined in the Purchaser Term Sheet.

                  (b) The Company will not, and will not permit its Subsidiaries
         to, agree, directly or indirectly, to any restriction with any person
         or entity that limits the ability of the Purchaser to consummate an
         Additional Financing with the Company or any of its Subsidiaries.

         7. Covenants of the Purchaser. The Purchaser covenants and agrees with
the Company as follows:

                  7.1 Confidentiality. The Purchaser will not disclose, and will
not include in any public announcement, the name of the Company, unless
expressly agreed to by the Company or unless and until such disclosure is
required by law or applicable regulation, and then only to the extent of such
requirement.

                  7.2 Non-Public Information. The Purchaser will not effect any
sales in the shares of the Company's Common Stock while in possession of
material, non-public information regarding the Company if such sales would
violate applicable securities law.

                  7.3 Limitation on Acquisition of Common Stock of the Company.
Notwithstanding anything to the contrary contained herein, in any Related
Agreement or any document, instrument or agreement entered into in connection
with any other transactions between the Purchaser and the Company, the Purchaser
may not acquire stock in the Company (including, without limitation, pursuant to
a contract to purchase, by exercising an option or warrant, by converting any
other security or instrument, by acquiring or exercising any other right to
acquire, shares of stock or other security convertible into shares of stock in
the Company, or otherwise, and such contracts, options, warrants, conversion or
other rights shall not be enforceable or exercisable) to the extent such stock
acquisition would cause any interest (including any original issue discount)
payable by the Company to Laurus not to qualify as "portfolio interest" within
the meaning of Section 881(c)(2) of the Code, by reason of Section

                                       20
<PAGE>

881(c)(3) of the Code, taking into account the constructive ownership rules
under Section 871(h)(3)(C) of the Code (the "Stock Acquisition Limitation"). The
Stock Acquisition Limitation shall automatically become null and void without
any notice to the Company upon the earlier to occur of either (a) the Company's
delivery to Laurus of a Notice of Redemption (as defined in the Note) or (b) the
existence of an Event of Default (as defined in the Note) at a time when the
average closing price of the Company's common stock as reported by Bloomberg,
L.P. on the Principal Market for the immediately preceding five trading days is
greater than or equal to 150% of the Fixed Conversion Price (as defined in the
Note).

         8. Covenants of the Company and the Purchaser Regarding
Indemnification.

                  8.1 Company Indemnification. The Company agrees to indemnify,

incurred by or imposed upon the Purchaser which result, arise out of or are
based upon: (i) any misrepresentation by the Company or any of its Subsidiaries
or breach of any warranty by the Company or any of its Subsidiaries in this
Agreement, any other Related Agreement or in any exhibits or schedules attached
hereto or thereto; or (ii) any breach or default in performance by Company or
any of its Subsidiaries of any covenant or undertaking to be performed by
Company or any of its Subsidiaries hereunder, under any other Related Agreement
or any other agreement entered into by the Company and/or any of its
Subsidiaries and the Purchaser relating hereto or thereto.

                  8.2 Purchaser's Indemnification. The Purchaser agrees to
indemnify, hold harmless, reimburse and defend the Company and each of the
Company's officers, directors, agents, affiliates, control persons and principal
shareholders, at all times against any claims, costs, expenses, liabilities,
obligations, losses or damages (including reasonable legal fees) of any nature,
incurred by or imposed upon the Company which result, arise out of or are based
upon: (i) any misrepresentation by the Purchaser or breach of any warranty by
the Purchaser in this Agreement or in any exhibits or schedules attached hereto
or any Related Agreement; or (ii) any breach or default in performance by the
Purchaser of any covenant or undertaking to be performed by the Purchaser
hereunder, or any other agreement entered into by the Company and the Purchaser
relating hereto.

         9. [RESERVED].

         10. Registration Rights.

                  10.1. The Company hereby grants registration rights to the

granted to employees or directors of the Company (these exceptions hereinafter
referred to as the "Excepted Issuances"), neither the Company nor any of its
Subsidiaries will, prior to the full repayment or conversion of the Note
(together with all accrued and unpaid interest and fees related thereto), (x)
enter into any equity

line of credit agreement or similar agreement or (y) issue, or enter into any
agreement to issue, any securities with a variable/floating conversion and/or
pricing feature which are or could be (by conversion or registration)

         11. Miscellaneous.

                  11.1     Governing Law, Jurisdiction and Waiver of Jury Trial.

                  (a) THIS AGREEMENT AND THE OTHER RELATED AGREEMENTS SHALL BE
         GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF
         THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN
         SUCH STATE, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

                  (b) THE COMPANY HEREBY CONSENTS AND AGREES THAT THE STATE OR
         FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK
         SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR
         DISPUTES BETWEEN THE COMPANY, ON THE ONE HAND, AND THE PURCHASER, ON
         THE OTHER HAND, PERTAINING TO THIS AGREEMENT OR ANY OF THE RELATED
         AGREEMENTS OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS AGREEMENT
         OR ANY OF THE OTHER RELATED AGREEMENTS; PROVIDED, THAT THE PURCHASER
         AND THE COMPANY ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE
         TO BE HEARD BY A COURT LOCATED OUTSIDE OF THE COUNTY OF NEW YORK, STATE
         OF NEW YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS AGREEMENT SHALL
         BE DEEMED OR OPERATE TO PRECLUDE THE PURCHASER FROM BRINGING SUIT OR
         TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION TO COLLECT THE
         OBLIGATIONS, TO REALIZE ON THE COLLATERAL (AS DEFINED IN THE MASTER
         SECURITY AGREEMENT) OR ANY OTHER SECURITY FOR THE OBLIGATIONS (AS
         DEFINED IN THE MASTER SECURITY AGREEMENT), OR TO ENFORCE A JUDGMENT OR
         OTHER COURT ORDER IN FAVOR OF THE PURCHASER. THE COMPANY EXPRESSLY
         SUBMITS AND CONSENTS IN ADVANCE TO SUCH JURISDICTION IN ANY ACTION OR
         SUIT COMMENCED IN ANY SUCH COURT, AND THE COMPANY HEREBY WAIVES ANY
         OBJECTION THAT IT MAY HAVE BASED UPON LACK OF PERSONAL JURISDICTION,
         IMPROPER VENUE OR FORUM NON CONVENIENS.

                  (c) THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A

         RELATED AGREEMENT OR THE TRANSACTIONS RELATED HERETO OR THERETO.

                  11.2 Severability. Wherever possible each provision of this
Agreement and the Related Agreements shall be interpreted in such manner as to
be effective and valid under applicable law, but if any provision of this
Agreement or any Related Agreement shall be prohibited by or invalid under
applicable law such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions thereof.

                  11.3 Survival. The representations and warranties of the
parties hereto contained in this Agreement shall survive the Closing for a
period of eighteen (18) months after the Closing; provided, however, that any

shall survive until such claim is finally and fully resolved. All covenants and
agreements contained herein shall remain in full force and effect for a period
of eighteen (18) months following the Closing, except for those covenants and
agreements that by their terms are to be performed in whole or in part after the
Closing, which shall remain in full force and effect for a period of eighteen
(18) months following the date by which such covenant or agreement is required
to be performed; provided, however, that any claim made with reasonable
specificity by the party seeking to be indemnified pursuant to Section 8 within
the time periods set forth in this Section 11.3 shall survive until such claim

upon, the successors, heirs, executors and administrators of the parties hereto
and shall inure to the benefit of and be enforceable by each entity which shall

effective registration statement. The Purchaser may not assign its rights
hereunder to a competitor of the Company.

Related Agreements, the exhibits and schedules hereto and thereto and the other
documents delivered pursuant hereto constitute the full and entire understanding
and agreement between the parties with regard to the subjects hereof and no
party shall be liable or bound to any other in any manner by any
representations, warranties, covenants and agreements except as specifically set
forth herein and therein. Nothing contained herein or in any document referred
to herein or delivered in connection herewith shall be deemed to establish or
require the payment of a rate of interest or other charges in excess of the
maximum permitted by applicable law. In the event that the rate of interest or
dividends required to be paid or other charges hereunder exceed the maximum
amount permitted by such law, any payments in excess of such maximum shall be
credited against amounts owed by the Company to the Purchaser and thus refunded
to the Company.

omission to exercise any right, power or remedy accruing to any party, upon any
breach, default or noncompliance by another party under this Agreement or the
Related Agreements, shall impair any such right, power or remedy, nor shall it

acquiescence therein, or of or in any similar breach, default or noncompliance
thereafter occurring. All remedies, either under this Agreement or the Related
Agreements, by law or otherwise afforded to any party, shall be cumulative and

                   SECURED CONVERTIBLE MINIMUM BORROWING NOTE
                   ------------------------------------------

                  FOR VALUE RECEIVED, each of RIVIERA TOOL COMPANY, a Michigan
corporation (the "COMPANY") promises to pay to LAURUS MASTER FUND, LTD., c/o M&C
Corporate Services Limited, P.O. Box 309 GT, Ugland House, South Church Street,
George Town, Grand Cayman, Cayman Islands, Fax: 345-949-8080 (the "HOLDER") or
its registered assigns or successors in interest, the sum of Two Million Dollars
($2,000,000), or, if different, the aggregate principal amount of all
outstanding Loans (as defined in the Security Agreement referred to below)
without duplication of any amounts owing by the Company to the Holder under the
Revolving Note (as defined in the Security Agreement referred to below),
together with any accrued and unpaid interest hereon, on May 17, 2008 (the
"MATURITY DATE") if not sooner paid.

                  Capitalized terms used herein without definition shall have
the meanings ascribed to such terms in the Security Agreement among the Company
and the Holder dated as of the date hereof (as amended, modified and
supplemented from time to time, the "SECURITY AGREEMENT").

                 The following terms shall apply to this Secured Convertible
Minimum Borrowing Note (the "NOTE"):

                                    ARTICLE I
                                  CONTRACT RATE

                  1.1 Contract Rate. Subject to Sections 4.2 and 5.10, interest
payable on the outstanding principal amount of this Note (the "PRINCIPAL
AMOUNT") shall accrue at a rate per annum equal to the "prime rate" published in
The Wall Street Journal from time to time (the "PRIME RATE"), plus one and one
quarter percent (1.25%) (the "CONTRACT RATE"). The Contract Rate shall be
increased or decreased as the case may be for each increase or decrease in the
Prime Rate in an amount equal to such increase or decrease in the Prime Rate;
each change to be effective as of the day of the change in the Prime Rate.
Subject to Section 1.2, the Contract Rate shall not be less than six and one
half percent (6.50%).

                  1.2 Contract Rate Adjustments and Payments. The Contract Rate
shall be calculated on the last business day of each calendar month hereafter
(other than for increases or decreases in the Prime Rate which shall be
calculated and become effective in accordance with the terms of Section 1.1)
until the Maturity Date (each a "DETERMINATION DATE") and shall be subject to
adjustment as set forth herein. If (i) the Company shall have registered the
shares of

                                       1
<PAGE>

the Common Stock underlying the conversion of each Minimum Borrowing Note and
each Option on a registration statement declared effective by the Securities and
Exchange Commission (the "SEC"), and (ii) the market price (the "MARKET PRICE")
of the Common Stock as reported by Bloomberg, L.P. on the Principal Market for
the five (5) trading days immediately preceding a Determination Date exceeds the
then applicable Fixed Conversion Price by at least twenty-five percent (25%),
the Contract Rate for the succeeding calendar month shall automatically be
reduced by 200 basis points (200 b.p.) (2%) for each incremental twenty-five
percent (25%) increase in the Market Price of the Common Stock above the then
applicable Fixed Conversion Price. Notwithstanding the foregoing (and anything
to the contrary contained herein), in no event shall the Contract Rate be less
than zero percent (0%). Interest shall be (i) calculated on the basis of a 360
day year, and (ii) payable monthly, in arrears, commencing on June 1, 2005 and
on the first business day of each consecutive calendar month thereafter until
the Maturity Date (and on the Maturity Date), whether by acceleration or
otherwise. For the avoidance of doubt, all determinations with respect to market
price and trading volume of the Common Stock shall be made based upon
information reported by Bloomberg, L.P. on the relevant date(s).

                                   ARTICLE II
                         LOANS; PAYMENTS UNDER THIS NOTE

                  2.1 Loans. All Loans evidenced by this Note shall be made in
accordance with the terms and provisions of the Security Agreement.

                  2.2 No Effective Registration. Notwithstanding anything to the
contrary herein, the Holder shall not be required to accept shares of Common
Stock as payment following a conversion by the Holder if there fails to exist an
effective current Registration Statement (as defined in the Registration Rights
Agreement) covering the shares of Common Stock to be issued, or if an Event of
Default hereunder exists and is continuing, unless such requirement is otherwise
waived in writing by the Holder in whole or in part at the Holder's option.

                  2.3 Optional Redemption in Cash. The Company will have the
option of prepaying this Note ("OPTIONAL REDEMPTION") by paying to the Holder a
sum of money equal to one hundred twenty percent (120%) of the principal amount
of this Note together with accrued but unpaid interest thereon and any and all
other sums due, accrued or payable to the Holder arising under this Note, the
Security Agreement, or any other Ancillary Agreement (the "REDEMPTION AMOUNT")
outstanding on the Redemption Payment Date (as defined below). The Company shall
deliver to the Holder a written notice of redemption (the "NOTICE OF
REDEMPTION") specifying the date for such Optional Redemption (the "REDEMPTION
PAYMENT DATE"), which date shall be seven (7) days after the date of the Notice
of Redemption (the "REDEMPTION PERIOD"). A Notice of Redemption shall not be
effective with respect to any portion of this Note for which the Holder has
previously delivered a Notice of Conversion (defined below) pursuant to Section
3.1, or for conversions elected to be made by the Holder pursuant to Section 3.1
during the Redemption Period. The Redemption Amount shall be determined as if
such Holder's conversion elections had been completed immediately prior to the
date of the Notice of Redemption. On the Redemption Payment Date, the Redemption
Amount (plus any additional interest and fees accruing on the Notes during the
Redemption Period) must be irrevocably paid in full in immediately available
funds to the Holder. In the event the

                                       2
<PAGE>

Companies fail to pay the Redemption Amount on the Redemption Payment Date, then
such Redemption Notice shall be null and void.

                                   ARTICLE III
                  CONVERSION RIGHTS AND FIXED CONVERSION PRICE

                  3.1   Optional Conversion. Subject to the terms of this
Article III, the Holder shall have the right, but not the obligation, at any
time until the Maturity Date, or during an Event of Default (as defined in
Article IV), and, subject to the limitations set forth in Section 3.2 hereof, to
convert all or any portion of the outstanding Principal Amount and/or accrued
interest and fees due and payable into fully paid and nonassessable shares of
the Common Stock at the Fixed Conversion Price. For purposes hereof, subject to
Section 3.6 hereof, the initial "FIXED CONVERSION PRICE" means $1.66. The shares
of Common Stock to be issued upon such conversion are herein referred to as the
"CONVERSION SHARES."

                  3.2   Conversion Limitation. Notwithstanding anything
contained herein to the contrary, the Holder shall not be entitled to exercise
pursuant to the terms of this Note an amount that would be convertible into that
number of shares of Common Stock which would exceed the difference between the
number of shares of Common Stock beneficially owned by such Holder or issuable
upon exercise of any option or warrant held by such Holder and 4.99% of the
outstanding shares of Common Stock of the Company. For the purposes of the
immediately preceding sentence, beneficial ownership shall be determined in
accordance with Section 13(d) of the Exchange Act and Regulation 13d-3
thereunder. The limitation described in this Section 3.2 shall automatically
become null and void without any notice to the Company upon the occurrence and
during the continuance beyond any applicable grace period of an Event of
Default, or upon 65 days prior notice to the Company, except that at no time
shall the beneficial ownership exceed 19.99% of the Common Stock.
Notwithstanding anything contained herein to the contrary, the number of shares
of Common Stock issuable by the Company and acquirable by the Holder at a price
below $1.10 per share pursuant to the terms of this Note, the Revolving Note (as
defined in the Security Agreement), the Security Agreement, any Ancillary
Agreement, the Secured Convertible Term Note made by the Company to the Holder
dated the date hereof (as amended, modified and/or supplemented from time to
time, the "TERM NOTE"), the Purchase Agreement (as defined in the Term Note) or
any Related Agreement (as defined in the Term Note) shall not exceed an
aggregate of 754,492 shares of the Company's Common Stock (subject to
appropriate adjustment for stock splits, stock dividends, or other similar
recapitalizations affecting the Common Stock) (the "MAXIMUM COMMON STOCK
ISSUANCE"), unless the issuance of shares hereunder in excess of the Maximum
Common Stock Issuance shall first be approved by the Company's shareholders. If
at any point in time and from time to time the number of shares of Common Stock
issued pursuant to the terms of this Note, the Revolving Note, the Security
Agreement, any Ancillary Agreement, the Term Note, the Purchase Agreement or any
Related Agreement together with the number of shares of Common Stock that would
then be issuable by the Company to the Holder in the event of a conversion or
exercise pursuant to the terms of this Note, the Revolving Note, the Security
Agreement, any Ancillary Agreement, the Term Note, the Purchase Agreement or any
Related Agreement would exceed the Maximum Common Stock Issuance but for this
paragraph, the Company shall promptly call a shareholders meeting to solicit
shareholder approval for the issuance of the shares of Common Stock hereunder in
excess of the Maximum Common Stock Issuance. Shares of Common Stock which

                                       3
<PAGE>

may not be issued due to the limitations set forth in this Section 3.2 shall not
be deemed to be Conversion Shares under this Note unless and until their
issuance is otherwise permitted as contemplated herein.

                  3.3   Mechanics of Holder's Conversion. In the event that the
Holder converts amounts outstanding under this Note into Common Stock, the
Holder shall give notice of such election by delivering (by facsimile or email)
an executed and completed notice of conversion in substantially the form of
Exhibit A hereto (appropriately completed) ("NOTICE OF CONVERSION") to the
Company and such Notice of Conversion shall provide a breakdown in reasonable
detail of the Principal Amount, accrued interest and fees that are being
converted. The Company shall have two and one half (2.5) hours from the time
that such Notice of Conversion is delivered to the Company (which Notice of
Conversion shall be delivered via facsimile or email by the Holder to each of
Peter Canepa, Kenneth Rieth and John LeHoty) to provide the Holder with written
notice (delivered to Holder via facsimile or email) of the Company's decision to
purchase the number of shares of Common Stock otherwise deliverable to the
Holder pursuant to the Notice of Conversion (the "DESIGNATED Shares") for a
purchase price determined by multiplying the Designated Shares by the intraday
high price of the Common Stock on the day the Notice of Conversion was submitted
to the Company (the "DISPOSITION PRICE"). The Disposition Price shall be paid by
the Company to the Holder by wire transfer of immediately available funds within
two (2) Business Days of the date of the Notice of Conversion. On each
Conversion Date (as hereinafter defined) and in accordance with its Notice of
Conversion, the Holder shall make the appropriate reduction to the Principal
Amount, accrued interest and fees as entered in its records and shall provide
written notice thereof to the Company within two (2) Business Days after the
Conversion Date. Each date on which a Notice of Conversion is delivered or
telecopied to the Company in accordance with the provisions hereof shall be
deemed a Conversion Date (the "CONVERSION DATE"). Pursuant to the terms of the
Notice of Conversion, the Company shall cause the transfer agent to transmit the
certificates representing the Conversion Shares to the Holder by crediting the
account of the Holder's designated broker with the Depository Trust Corporation
("DTC") through its Deposit Withdrawal Agent Commission ("DWAC") system within
three (3) Business Days after receipt by the Company of the Notice of Conversion
(the "DELIVERY DATE"). In the case of the exercise of the conversion rights set
forth herein the conversion privilege shall be deemed to have been exercised and
the Conversion Shares issuable upon such conversion shall be deemed to have been
issued upon the date of receipt by the Company of the Notice of Conversion. The
Holder shall be treated for all purposes as the record holder of the Conversion
Shares, unless the Holder provides the Company written instructions to the
contrary.

                  3.4   Late Payments. The Company understands that a delay in
the delivery of the Conversion Shares in the form required pursuant to this
Article beyond the Delivery Date could result in economic loss to the Holder. As
compensation to the Holder for such loss, the Company shall pay late payments to
the Holder for any late issuance of Conversion Shares in the form required
pursuant to this Article III upon conversion of this Note, in the amount equal
to $500 per Business Day after the Delivery Date. The Company shall make any
payments incurred under this Section in immediately available funds upon demand.
Notwithstanding the foregoing, the Company will not owe the Holder any late
payments if the delay in the delivery of the Note Shares beyond the Delivery
Date is solely out of the control of the Company and the Company is actively
trying to cure the cause of the delay. The Company shall pay any payments

                                       4
<PAGE>

incurred under this Section in immediately available funds upon demand and, in
the case of actual damages, accompanied by reasonable documentation of the
amount of such damages. Such documentation shall show the number of shares of
Common Stock the Holder is forced to purchase (in an open market transaction)
which the Holder anticipated receiving upon such conversion, and shall be
calculated as the amount by which (A) the Holder's total purchase price
(including customary brokerage commissions, if any) for the shares of Common
Stock so purchased exceeds (B) the aggregate principal and/or interest amount of
the Note, for which such Conversion Notice was not timely honored.

                  3.5   Conversion Mechanics. The number of shares of Common
Stock to be issued upon each conversion of this Note shall be determined by
dividing that portion of the principal and interest and fees to be converted, if
any, by the then applicable Fixed Conversion Price.

                  3.6   Adjustment Provisions. The Fixed Conversion Price and
number and kind of shares or other securities to be issued upon conversion
determined pursuant to Section 3.1 shall be subject to adjustment from time to
time upon the happening of certain events while this conversion right remains
outstanding, as follows:

                        (a) Reclassification. If the Company at any time
shall, by reclassification or otherwise, change the Common Stock into the same
or a different number of securities of any class or classes, this Note, as to
the unpaid Principal Amount and accrued interest thereon, shall thereafter be
deemed to evidence the right to purchase an adjusted number of such securities
and kind of securities as would have been issuable as the result of such change
with respect to the Common Stock (i) immediately prior to, or (ii) immediately
after such reclassification or other change at the sole election of the Holder.

                        (b) Stock Splits, Combinations and Dividends. If the
shares of Common Stock are subdivided or combined into a greater or smaller
number of shares of Common Stock, or if a dividend is paid on the Common Stock
or any preferred stock issued by the Company in shares of Common Stock, the
Fixed Conversion Price shall be proportionately reduced in case of subdivision
of shares or stock dividend or proportionately increased in the case of
combination of shares, in each such case by the ratio which the total number of
shares of Common Stock outstanding immediately after such event bears to the
total number of shares of Common Stock outstanding immediately prior to such
event.

                           (c) Share Issuances. Subject to the provisions of
this Section 3.6, if the Company shall at any time prior to the conversion or
repayment in full of the Principal Amount issue any shares of Common Stock or
securities convertible into Common Stock to a person other than the Holder
(except (i) pursuant to Sections 3.6(a) or (b) above; (ii) pursuant to options,
warrants, or other obligations to issue shares outstanding on the date hereof as
disclosed to the Holder in writing; or (iii) pursuant to options that may be
issued under any employee incentive stock option and/or any qualified stock
option plan adopted by the Company) for a consideration per share (the "OFFER
PRICE") less than the Fixed Conversion Price in effect at the time of such
issuance, then the Fixed Conversion Price shall be immediately reset pursuant to
the formula set forth below. For purposes hereof, the issuance of any security
of the Company convertible into or exercisable or exchangeable for Common Stock
shall result in an adjustment

                                       5
<PAGE>

to the Fixed Conversion Price upon the issuance of such securities pursuant to
the formula below.

                  If the Company issues any additional shares of Common
Stock for a consideration per share less than the then-applicable Fixed
Conversion Price pursuant to this Section 3.6 then, and thereafter successively
upon each such issue, the Fixed Conversion Price shall be adjusted by
multiplying the then applicable Fixed Conversion Price by the following
fraction:

                ---------------------------------------
                                A + B
                ---------------------------------------
                    (A + B) + [((C - D) x B) / C]
                ---------------------------------------

            A =  Total amount of shares convertible pursuant to the Notes

            B =  Actual shares sold in the offering

            C =  Fixed Conversion Price

            D =  Offer Price

Such adjustment shall become effective immediately upon the earlier to occur of
the date of issuance of such shares of Common Stock or the record date for the
determination of stockholders entitled to receive the convertible securities, as
the case may be.

                        (d) Computation of Consideration. For purposes of any
computation respecting consideration received pursuant to Section 3.6(c) above,
the following shall apply:

                            (i)   in the case of the issuance of shares of
          Common Stock for cash, the consideration shall be the amount of such
          cash, provided that in no case shall any deduction be made for any
          commissions, discounts or other expenses incurred by the Company for
          any underwriting of the issue or otherwise in connection therewith;

                            (ii)  in the case of the issuance of shares
          of Common Stock for a consideration in whole or in part other than
          cash, the consideration other than cash shall be deemed to be the fair
          market value thereof as determined in good faith by the Board of
          Directors of the Company (irrespective of the accounting treatment
          thereof); and

                            (iii) upon any such exercise, the aggregate
          consideration received for such securities shall be deemed to be the
          consideration received by the Company for the issuance of such
          securities plus the additional minimum consideration, if any, to be
          received by the Company upon the conversion or exchange thereof (the
          consideration in each case to be determined in the same manner as
          provided in subsections (i) and (ii) of this Section 2.5).

                  3.7   Reservation of Shares. During the period the conversion
right exists, the Company will reserve from its authorized and unissued Common
Stock a sufficient number of shares to provide for the issuance of Conversion
Shares upon the full conversion of this Note. The Company represents that upon
issuance, the Conversion Shares will be duly and validly

                                       6
<PAGE>

issued, fully paid and non-assessable. The Company agrees that its issuance of
this Note shall constitute full authority to its officers, agents, and transfer
agents who are charged with the duty of executing and issuing stock certificates
to execute and issue the necessary certificates for the Conversion Shares upon
the conversion of this Note.

                  3.8   Registration Rights. The Holder has been granted
registration rights with respect to the Conversion Shares as set forth in a
Registration Rights Agreement.

                                   ARTICLE IV
                EVENTS OF DEFAULT AND DEFAULT RELATED PROVISIONS

                  4.1   Events of Default. The occurrence of an Event of Default
under the Security Agreement shall constitute an event of default ("EVENT OF
DEFAULT") hereunder.

                  4.2   Default Interest. Following the occurrence and during
the continuance of an Event of Default, the Company shall pay additional
interest on the outstanding principal balance of this Note in an amount equal to
one and one half percent (1.50%) per month, and all outstanding Obligations,
including unpaid interest, shall continue to accrue interest at such additional
interest rate from the date of such Event of Default until the date such Event
of Default is cured or waived.

                  4.3   Default Payment. Following the occurrence and during the
continuance of an Event of Default, the Holder, at its option, may elect, in
addition to all rights and remedies of the Holder under the Security Agreement
and the Ancillary Agreements and all obligations of the Company under the
Security Agreement and the Ancillary Agreements, to require the Company to make
a Default Payment ("DEFAULT Payment"). The Default Payment shall be one hundred
twenty percent (120%) of the outstanding principal amount of the Note, plus
accrued but unpaid interest, all other fees then remaining unpaid, and all other
amounts payable hereunder. The Default Payment shall be applied first to any
fees due and payable to the Holder pursuant to the Notes and/or the Ancillary
Agreements, then to accrued and unpaid interest due on the Notes and then to the
outstanding principal balance of the Notes. The Default Payment shall be due and
payable immediately on the date that the Holder has exercised its rights
pursuant to this Section 4.3.

                                    ARTICLE V
                                  MISCELLANEOUS

                  5.1   Conversion Privileges. The conversion privileges set
forth in Article III shall remain in full force and effect immediately from the
date hereof until the date this Note is indefeasibly paid in full and
irrevocably terminated.

                  5.2   Cumulative Remedies.  The remedies under this Note shall

 be cumulative.

                  5.3   Failure or Indulgence Not Waiver. No failure or delay on
the part of the Holder hereof 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. All rights and

                                       7
<PAGE>

remedies existing hereunder are cumulative to, and not exclusive of, any rights
or remedies otherwise available.

                  5.4   Notices. Any notice herein required or permitted to be
given shall be in writing and provided in accordance with the terms of the
Security Agreement.

                  5.5   Amendment Provision. The term "Note" and all references
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, and any successor instrument as such successor instrument may be
amended or supplemented.

                  5.6   Assignability. This Note shall be binding upon the
Company and its successors and assigns, and shall inure to the benefit of the
Holder and its successors and assigns, and may be assigned by the Holder in
accordance with the requirements of the Security Agreement. No Company may
assign any of its obligations under this Note without the prior written consent
of the Holder, any such purported assignment without such consent being null and
void.

                  5.7   Cost of Collection. In case of any Event of Default
under this Note, the Company shall pay the Holder's reasonable costs of
collection, including reasonable attorneys' fees.

                  5.8   Governing Law, Jurisdiction and Waiver of Jury Trial.

                        (a) THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO
PRINCIPLES OF CONFLICTS OF LAW.

                        (b) THE COMPANY HEREBY CONSENTS AND AGREES THAT THE
STATE OR FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK
SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES
BETWEEN ANY COMPANY, ON THE ONE HAND, AND THE HOLDER, ON THE OTHER HAND,
PERTAINING TO THIS NOTE, THE SECURITY AGREEMENT OR ANY OF THE OTHER ANCILLARY
AGREEMENTS OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS NOTE, THE SECURITY
AGREEMENT OR ANY OF THE OTHER ANCILLARY AGREEMENTS; PROVIDED, THAT THE COMPANY
ACKNOWLEDGES THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT
LOCATED OUTSIDE OF THE COUNTY OF NEW YORK, STATE OF NEW YORK; AND FURTHER
PROVIDED, THAT NOTHING IN THIS NOTE SHALL BE DEEMED OR OPERATE TO PRECLUDE THE
HOLDER FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER JURISDICTION
TO COLLECT THE OBLIGATIONS, TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY
FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF
THE HOLDER. THE COMPANY EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH
JURISDICTION IN ANY ACTION OR SUIT COMMENCED IN ANY SUCH COURT, AND THE COMPANY
HEREBY WAIVES ANY OBJECTION WHICH IT MAY HAVE BASED

                                       8
<PAGE>

UPON LACK OF PERSONAL JURISDICTION, IMPROPER VENUE OR FORUM NON CONVENIENS.

                        (c) THE COMPANY DESIRES THAT ITS DISPUTES BE RESOLVED
BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST
COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE
COMPANY HERETO WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR
PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, WHETHER ARISING IN CONTRACT, TORT, OR
OTHERWISE BETWEEN THE HOLDER, AND/OR ANY COMPANY ARISING OUT OF, CONNECTED WITH,
RELATED OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION
WITH THIS NOTE, THE SECURITY AGREEMENT, ANY OTHER ANCILLARY AGREEMENT OR THE
TRANSACTIONS RELATED HERETO OR THERETO.

                  5.9   Severability. In the event that any provision of this
Note is invalid or unenforceable under any applicable statute or rule of law,
then such provision shall be deemed inoperative to the extent that it may
conflict therewith and shall be deemed modified to conform with such statute or
rule of law. Any such provision which may prove invalid or unenforceable under
any law shall not affect the validity or enforceability of any other provision
of this Note.

                  5.10  Maximum Payments. Nothing contained herein shall be
deemed to establish or require the payment of a rate of interest or other
charges in excess of the maximum permitted by applicable law. In the event that
the rate of interest required to be paid or other charges hereunder exceed the
maximum rate permitted by such law, any payments in excess of such maximum rate
shall be credited against amounts owed by the Company to the Holder and thus
refunded to the Company.

                  5.11  Security Interest and Guarantee. The Holder has been
granted a security interest (i) in certain assets of the Company as more fully
described in the Security Agreement, and (ii) pursuant to the Master Security
Agreement and the Stock Pledge Agreement, each dated as of the date hereof. The
obligations of the Company under this Note shall be guaranteed by each
Subsidiary of the Company pursuant to a Subsidiary Guaranty.

                  5.12  Construction. Each party acknowledges that its legal
counsel participated in the preparation of this Note and, therefore, stipulates
that the rule of construction that ambiguities are to be resolved against the
drafting party shall not be applied in the interpretation of this Note to favor
any party against the other.
