ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

    (a)  On May 21, 1996, USAT purchased all of the outstanding shares of Common
Stock (the "RSA Common Stock") of Robert Stutman & Associates, Inc., a
Massachusetts corporation ("RSA"), for $2,500,000, pursuant to a Stock Purchase
Agreement dated as of May 21, 1996 (the "Purchase Agreement"), a copy of which
Purchase Agreement is filed as Exhibit A to this Report and which is
incorporated herein by this reference. At the closing, USAT paid $2,100,000 to
the stockholders of RSA, including Robert Stutman, the Chairman and Chief
Executive Officer of USAT, who received $1,078,920 for his 42.2 shares of the
RSA Common Stock (there being 80 shares outstanding). Brian Stutman, the
Director of Sales and Marketing of USAT, received $721,080 for his 28.2 shares
of the RSA Common Stock. Robert Stutman and Brian Stutman, who are father and
son, also received at the closing secured promissory notes each due May 20,
1997, the former's in principal amount of $239,760 and the latter's in the
principal amount of $160,240, each bearing interest at the annual rate of seven
and one-half percent. If USAT receives, after April 17, 1996, $7,000,000 in
proceeds from the exercises of Common Stock purchase warrants, then the notes
must be prepaid. The form of the secured promissory notes is filed as Exhibit B
to this Report and is incorporated herein by this reference. The promissory
notes are secured by all of USAT's tangible and intangible personal property
except the following: (1) USAT's cash and cash equivalents; (2) USAT's
securities, including stock of its subsidiaries; and (3) certain contracts,
including USAT's license agreement with the United States Department of the
Navy. The form of security agreement is filed as Exhibit C to this Report and is
incorporated herein by this reference.

    Pursuant to the Purchase Agreement, USAT issued to the stockholders of RSA
an aggregate of 500,000 shares of USAT's Common Stock, $.01 par value (the
"Common Stock"), and Warrants expiring May 21, 1999 (the "Acquisition Warrants")
to purchase an aggregate of 900,000 shares of the Common Stock at a price of
$3.125 per share. At the closing, Robert Stutman received 263,750 shares of the
Common Stock and an Acquisition Warrant to purchase 474,750 shares of the Common
Stock. Brian Stutman received 176,250 shares of the Common Stock and an
Acquisition Warrant to purchase 317,250 shares of the Common Stock. The form

                                        2
<PAGE>   3
of Acquisition Warrant is filed as Exhibit D to this Report and is incorporated
herein by this reference.

    USAT granted certain registration rights under the Securities Act of 1933,
as amended (the "Securities Act"), to the RSA stockholders. The form of
registration rights agreement is filed as Exhibit E to this Report and is
incorporated herein by this reference. However, the 500,000 shares issued at the
closing were allocated by USAT's Board of Directors from the 2,032,679 shares
which are reserved for acquisitions and which were registered in USAT's
Registration Statement on Form S-1, File No. 33-43337, under the Securities Act.

    The Company used its own funds for this acquisition, including those derived
from the exercise of outstanding Common Stock purchase warrants. No funds were
borrowed in connection with this acquisition.

    Robert Stutman, the Chairman and President of RSA, became the Chairman and
Chief Executive Officer of USAT on April 18, 1996. Prior thereto, he and RSA
were serving as consultants to USAT and its wholly-owned subsidiary ProActive
Synergies, Inc. ("ProActive") pursuant to a Consulting Agreement dated as of
December 14, 1996 by and among USAT, ProActive, RSA and Robert Stutman, a copy
of which Consulting Agreement is filed (by incorporation by reference) as
Exhibit F to this Report and which is incorporated herein by this reference. As
a result of the acquisition, the Consulting Agreement has been terminated.

    At the closing, USAT entered into severance agreements with Robert Stutman
and Brian Stutman, copies of which are filed as Exhibit G and H, respectively,
to this Report and which are incorporated herein by this reference.

    (b) As previously reported in (i) a Press Release dated May 1, 1996, a copy
of which is filed as Exhibit I to this Report and is incorporated herein by this
reference, (ii) USAT's Supplement dated May 6, 1996 to its Prospectus dated
January 31, 1996, which constitutes Part I of USAT's Registration Statement on
Form S-1, File Number 33-90034, a copy of which Supplement is filed (by
incorporation by reference) as Exhibit J to this Report and is incorporated
herein by this reference, and (iii) the preliminary prospectus constituting Part
I of USAT's Registration Statement on Form S-4, File No. 333-3734, on April 30,
1996, USAT's wholly- owned subsidiary U.S. Rubber Recycling, Inc. ("USRR") sold
substantially all of its assets to Reclamation Resources, Inc. ("RRI") for
$500,000. A copy of the Asset Purchase Agreement dated April 30, 1996 between
USRR and RRI is filed as Exhibit K to this Report and is incorporated herein by
this reference.

    The $500,000 purchase price was paid as follows: (1) a $150,000 payment to
USRR at the closing; (2) a $50,000 credit for

                                        3
<PAGE>   4
a closing adjustment; and (3) a promissory note from RRI to USRR in the
principal amount of $300,000, payable in six annual installments of $50,000,
together with interest thereon at an annual rate of seven percent. The
promissory note is prepayable to the extent that RRI's net sales exceed
$1,400,000. In the event that net sales exceed this amount, USRR will receive
12.5% of the excess. The promissory note is secured by a lien on all of RRI's
assets.

    USRR generated approximately 21.2% of the Company's revenues for the
nine-month period ended December 31, 1995. USRR generated 25.3% of the Company's
revenues for the fiscal year ended March 31, 1995.

         4. REPRESENTATIONS AND WARRANTIES OF THE SELLERS. The Sellers, jointly
and severally, represent and warrant to the Purchaser as follows:

                 4.1 ORGANIZATION. The Company is a corporation duly organized,
validly existing and in good standing under the laws of the Commonwealth of
Massachusetts and has all requisite power and authority, corporate or otherwise,
to own, lease and operate its properties and to carry on its business as and in
the places where such properties are now owned, leased or operated or such
business is now being conducted. Complete and correct copies of the Certificate
of Incorporation of the Company and all amendments thereto, certified in each
case by the Clerk of the State of the state of incorporation, and of the By-Laws
of the Company and all amendments thereto, certified by the Secretary of the
Company, have been heretofore delivered to the Purchaser. The Company is duly
qualified to do business and is in good standing in all jurisdictions (each such
jurisdiction is set forth in Schedule 4.1 hereto) in which such qualification is
necessary because of the character of the properties owned, leased or operated
by it or the nature of its activities. The Company has not taken any action and
has not failed to take any action, which action or failure would preclude or
prevent the

                                        5
<PAGE>   6
Purchaser from conducting the business of the Company in the manner heretofore
conducted. The Seller does not have any subsidiaries.

                 4.2 CAPITALIZATION. The Company has no authorized or
outstanding securities other than the Common Stock, which consists of One
Hundred (100) authorized shares, of which Eighty (80) shares are issued and
outstanding. Twenty (20) shares of the Common Stock are reserved for issuance
and there are seventeen (17) shares in the treasury of the Company. All
outstanding shares of the Common Stock are duly authorized, validly issued,
fully paid and nonassessable, and, except as set forth on Schedule 4.2, there
are no authorized, issued or outstanding securities of the Seller convertible
into Common Stock nor are there any outstanding options, warrants, agreements,
rights or commitments of any kind relating to the authorized but unissued shares
of the Common Stock. All transfer taxes, if any, with respect to transfer of
securities of the Company made prior to the date hereof have been fully paid.
The eighty (80) issued and outstanding shares of the Common Stock are owned,
both beneficially and of record, by the Sellers as set forth in Section 1.1
hereof and are free and clear of any and all security interests, liens, pledges,
claims, charges, escrows, encumbrances, options, rights of first refusal,
mortgages, indentures, security agreements, shareholders agreements or other
contracts (whether or not relating in any way to credit or the

                                        6
<PAGE>   7
borrowing of money) and the Sellers have the unrestricted right to sell the
Shares to the Purchaser.

                 4.3 AUTHORIZATION, VALIDITY AND ENFORCEABILITY. This
Agreement has been duly executed and delivered by each of the Sellers and
constitutes the legal, valid and binding obligation of each of the Sellers, and
each of the other Transaction Documents to which any of the Sellers is a party
will, upon due execution and delivery thereof, constitute the legal, valid and
binding obligation of each of the Sellers, in each case enforceable against each
of the Sellers in accordance with the terms hereof or thereof, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and similar laws affecting creditor's rights and remedies generally,
and subject, as to enforceability, to general principles of equity, including
principles of commercial reasonableness, good faith and fair dealing (regardless
of whether enforcement is sought in a proceeding at law or equity). "Transaction
Documents" means the Security Agreement, Registration Rights Agreement, Notes
and Purchase Price Warrants and any other agreements or instruments required to

<PAGE>   16
Except as set forth in Schedule 4.11, each of the contracts and commitments
referred to therein is valid and existing, in full force and effect, and
enforceable in accordance with its terms, and no party thereto is in default and
no claim of default by any party has been made or is now pending, and no event
exists which, with or without the lapse of time or the giving of notice, or
both, would constitute a breach or default, cause acceleration of any
obligation, would permit the termination or excuse the performance by any party
thereto, or would otherwise adversely affect the business and/or assets of the
Company. Except for item 1 of Schedule 4.11, no consent of the parties to the
contracts set forth on Schedule 4.11 is required as a result of the sale of the
Shares by the Sellers to the Purchaser for such contracts to remain enforceable,
valid and in full force and effect.

customer in the ordinary course of business, the amount of which was actually
due on the date thereof and has been, or will be to the best of the Seller's
knowledge, collected in the ordinary course of business. The books and records
of the Company state correctly the facts with respect to each account receivable
of the Company and the balance due thereon. Each payment reflected in such books
and records as having been made on each such account receivable was made by the

                                       16

Schedule 4.12. There are no defenses, claims of disabilities, counterclaims,
offsets, refusals to pay or other rights of set-off against any accounts
receivable and there is no threatened, intended or proposed defense, claim of
disability, counterclaim, offset, refusal to pay or other right of set-off with
respect thereto. To the best of the Sellers' knowledge each account receivable
existing on the Closing Date will be paid in full.

leased in whole or in part by the Company. The Company has legal and valid
occupancy permits and other required licenses or government approvals for each
of the properties and premises leased, used or occupied by the Company (copies
of which have been heretofore delivered to the Purchaser). Each lease or other
agreement of the Company for real property is in full force and effect and is a
legal, valid and binding obligation as between the Company, as the case maybe,
and the other party or parties thereto and the Company, as the case maybe, is a
tenant or possessor in good standing thereunder, free of any default or breach
whatsoever, and the Company has the legal right (without the consent or other

payment due thereunder has been duly made; each act required to be performed
which, if not performed, would constitute a material breach thereof has been

which, if protested, would constitute a material breach thereof; and there is

event which, with or without notice or the lapse of time, or both, would
constitute a breach or default thereunder. No improvement, fixture or equipment

respect thereto, is in violation of any law, including, without limitation, any
zoning, building, safety, health or environmental law, and each of such premises
or properties is currently being used.

and the Transaction Documents and the performance by the Purchaser of its
obligations hereunder and thereunder have been duly authorized by all necessary
corporate action of the Purchaser and no further action or approval, corporate

                 5.5 CONFLICT. The execution and delivery of this Agreement or
the Transaction Documents, the consummation of the transactions contemplated
hereby or thereby, the fulfillment of the terms, conditions or provisions hereof
or thereof and the compliance with the terms, conditions or provisions hereof
and thereof (a) do not and will not conflict with, or violate any provision of,

and will not conflict with, or result in any breach of, any condition or
provision of, or constitute a default under, or give rise to any right of
termination, cancellation or acceleration under (whether after the giving of

indenture, license, franchise, instrument, order, judgment or decree to which
the Purchaser is a party or which is, or purports to be, binding upon the
Purchaser, or (c) will not be in violation of any statute, rule or regulation
applicable to the Purchaser.

                 5.6 PURCHASE FOR INVESTMENT. The Purchaser is acquiring the
Shares for investment purposes only and not with a view toward any distribution
thereof except in compliance with the Securities Act of 1933, as amended.

                 5.7 LEGAL PROCEEDINGS. Except as is set forth in Schedule 5.7,
there is no pending or overtly threatened action, suit, claim, proceeding or
investigation before any Governmental Authority against or involving the

aggregate together with

                                       28
<PAGE>   29
all such actions, suits, claims, proceedings or investigations, have a material
adverse effect on the ability of the Purchaser to perform its obligations, or
consummate the transactions contemplated, hereunder or under any other
Transaction Document to which the Purchaser is a party. Purchaser is not bound
by or subject to any order, judgment, injunction, award or decree of any
Governmental Authority or arbitration tribunal which has had or is reasonably
likely to have a material adverse effect on the ability of any Purchaser to
perform its obligations, or consummate the transactions contemplated, hereunder
or under any other Transaction Document to which the Purchaser is a party.

                 5.8 FINANCIAL STATEMENTS. The Purchaser has heretofore
delivered to the Sellers a copy of the Purchaser's financial statements for the
nine-month period ended December 31, 1995 which have been prepared by the
Purchaser's independent certified public accountants, and have been prepared in
accordance with generally accepted accounting principles consistently applied
throughout the periods indicated (the "USAT Financial Statements"). The USAT
Financial Statements (a) are true, correct and complete, (b) are in accordance
with the books and records of the Purchaser, and (c) fairly, completely and
accurately present the financial condition of the Purchaser at the dates
specified or the results of its operations for the periods covered. Except for
(a) liabilities reflected or reserved against in the Financial Statements, (b)
liabilities reflected in Schedule 5.8 hereto, or (c) liabilities incurred in

                                       29
<PAGE>   30
the ordinary course of business since December 31, 1995, the Purchaser has no
material liabilities or obligations.

                 5.9 TITLE. Except as set forth in the USAT Financial Statements
or on Schedule 5.9 hereto, the Company owns outright, and has good and
marketable title to, all of its assets, free and clear of any mortgage, lien,
security interest, pledge, charge, claim, conditional sale or other agreement,
lease, right or encumbrance of any sort.

                 5.10 TAXES. The Purchaser has duly filed all foreign, federal,
state, county and local income, excise, sales, property, withholding, social
security, franchise, license, information returns and other tax returns and
reports required to have been filed by the Purchaser prior to the date hereof.
Each such return is true, correct and complete and the Purchaser has paid all
taxing authorities with respect to all periods prior to the date hereof required
to have been paid by the Purchaser and created sufficient reserves or made
provision for all thereof accrued but not yet due and payable by it. The
Purchaser does not have any liability for any taxes, assessments, amounts,
interest or penalties of any nature whatsoever except as reserved against in the
Purchaser's balance sheet dated as of December 31, 1995 (the "USAT Balance
Sheet") and there is no basis for any additional claim or assessment other than
with respect to liabilities for taxes which may have accrued in the ordinary
course of business since the date of the USAT Balance Sheet. No government or
governmental authority is now asserting or

                                       30
<PAGE>   31
threatening to assert any deficiency or assessment for additional taxes or any
interest, penalties or fines with respect to the Purchaser.

                 5.11 LITIGATION. Except as set forth in Schedule 5.11 hereto,
no material action, suit, claim, arbitration, governmental, investigation or
proceeding, whether legal or administrative or in mediation or arbitration, is
pending, at law or in equity or admiralty, before or by any court or federal,
state, municipal or other governmental department, commission, board, bureau,
agency or instrumentality, (i) against or affecting the Purchaser or any of the
assets or business, operations, financial condition or prospects of the
Purchaser or (ii) in which an unfavorable judgment, decree or order would
restrain, prohibit, invalidate, set aside, rescind, prevent or make unlawful
this Agreement or the carrying out of this Agreement or the transactions
contemplated hereby; nor is there any basis for any such action, suit, claim,
investigation or proceeding. Except as set forth in Schedule 5.11 hereto, there
is no pending action, suit or proceeding which has been brought by or on behalf
of the Purchaser in any court or before any governmental agency or arbitration
tribunal. The Purchaser is not in default with respect to any order, writ,
information or decree of any court or any federal, state, municipal or other
governmental department, bureau, agency or instrumentality.

                 5.12 MATERIAL REPRESENTATIONS. No representation or warranty by
the Purchaser in this Agreement or under any

                                       31
<PAGE>   32
documents, instruments, certificates or schedules furnished pursuant hereto or
in connection with the transactions contemplated hereby contains any untrue
statement of a material fact or omits to state a material fact necessary to make
the statements of fact contained herein and therein not misleading. There is no
fact which adversely affects, or in the future may adversely affect, the
business, operations, affairs, condition or prospects of the Company which has
not been set forth in this Agreement or in the documents, instruments,
certificates or schedules furnished pursuant hereto or in the Purchaser's
Registration Statement on Form S-4 which was filed with the Securities and
Exchange Commission on May 6, 1996.

         6. RESTRICTIVE COVENANT. In consideration of a portion of the purchase
price, as set forth in Schedule 6.1, for a period of four (4) years after the
Closing Date, the R. Stutman and B. Stutman shall not:

                      6.1.1 directly or indirectly own any interest in, manage,
operate, join, control, participate in, invest in, or otherwise be connected in
any manner with, whether as an officer, director, employee, partner, investor or
otherwise, any business entity which is engaged in the United States, in any
business similar to the Purchased Business as conducted by the Company
immediately prior to the Closing. Nothing contained in this Section 6.1.1 shall
preclude R. Stutman or B. Stutman (a) while they are not employed by the
Purchaser, from owning not more than

                                       32
<PAGE>   33
two (2%) percent of the issued and outstanding shares of publicly traded common
stock of a corporation engaged in the Purchased Business or (b) from owning
shares in a mutual fund.

                      6.1.2 for itself or on behalf of any other person,
partnership, corporation or entity, be in contact in any way with any customer
or employee of the Company for the purpose of soliciting, diverting or taking
away any customer or employee of the Company.

                 6.2 CONFIDENTIALITY. At all times after the Closing Date, the
Sellers shall hold in a fiduciary capacity for the benefit of the Purchaser all
confidential and proprietary information, trade secrets, knowledge and data
relating to, or concerned with, the Company which is not in the public domain,
and they shall not at any time after the Closing Date use any such information,
knowledge, trade secrets or data for the benefit of any Person other than the
Purchaser or its designees, or disclose or divulge any such information,
knowledge, trade secrets or data to any Person, other than to the Purchaser or
its designees.

                 6.3 EQUITABLE RELIEF. The Sellers agree that the remedy at law
for any breach of the provisions of Sections 6.1 and 6.2 hereof will be
inadequate and that the Purchaser shall be entitled to injunctive relief to
compel the Sellers to perform or refrain from action required or prohibited
hereunder. The necessity of protection against the competition of the Sellers
and the nature and scope of such protection has been carefully

                                       33
<PAGE>   34
considered by the parties hereto. The parties hereby agree and acknowledge that
the duration, scope and geographic area applicable to the restrictions set forth
in this Section 6 are fair, reasonable and necessary. The consideration provided
for herein is sufficient and adequate to compensate the Sellers for agreeing to
the restrictions contained in this Section. If, however, any court determines
that the foregoing restrictions are not reasonable, such restrictions shall be
modified, rewritten or interpreted to include as much of their nature and scope
as will render them enforceable.

         7. SURVIVAL OF REPRESENTATIONS. All of the representations, warranties,
covenants and agreements made by the parties to this Agreement shall survive the
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereunder for a period of two (2) years.

         8. INDEMNIFICATION

                 8.1 BY PURCHASER. The Purchaser shall defend and promptly
indemnify the Sellers and save the Sellers harmless from, against, for and in
respect of, and shall pay all damages, losses, obligations, liabilities, claims,
encumbrances, deficiencies, costs and expenses, including, without limitation,
reasonable attorneys' fees and other costs and expenses incident to, any action,
investigation, claim or proceeding (all

                                       34
<PAGE>   35
hereinafter collectively referred to as "Losses") suffered, sustained, incurred
or required to be paid by the Sellers by reason of any breach or failure of
observance or performance of any representation, warranty, covenant, agreement
or commitment made by the Purchaser hereunder or relating hereto or as a result
of any such representation, warranty, covenant, agreement or commitment being
untrue or incorrect in any respect.

                 8.2 BY SELLERS. R. Stutman and B. Stutman shall, jointly and
severally, defend and promptly indemnify the Purchaser and save and hold the
Purchaser harmless from, against, for and in respect of, and pay any and all
damages, losses, obligations, liabilities, claims, encumbrances, deficiencies,
costs and expenses, including without limitation, reasonable attorneys' fees and
other costs and expenses incident to, any suit, action, investigation, claim or
proceeding (all hereinafter collectively referred to as "Losses") suffered,
sustained, incurred or required to be paid by the Purchaser by reason of any
breach or failure of observance or performance of any representation, warranty,
covenant, agreement or commitment made by the Sellers, hereunder or relating
hereto or as a result of any such representation, warranty, covenant, agreement
or commitment being untrue or incorrect in any respect.

                 8.3 CLAIM FOR INDEMNIFICATION. For purposes of this Article 8,
the party entitled to indemnification shall be known as the "Injured Party" and
the party required to indemnify shall be known as the "Other Party." In the
event that the Other Party

                                       35
<PAGE>   36
shall be obligated to the Injured Party pursuant to this Article 8, or in the
event that a suit, action, investigation, claim or proceeding is begun, made or
instituted as a result of which the Other Party may become obligated to the
Injured Party hereunder, the Injured Party shall give prompt written notice to
the Other Party of the occurrence of such event. The Other Party agrees to
defend, contest or otherwise protect against any such suit, action,
investigation, claim or proceeding at the Other Party's own cost and expense.
The Injured Party shall have the right, but not the obligation, to participate
at its own expense in the defense thereof by counsel of its own choice. In the
event that the Other Party fails to timely defend, contest or otherwise protect
against any such suit, action, investigation, claim or proceeding, the Injured
Party shall have the right to defend, contest or otherwise protect against the
same and may make any compromise or settlement thereof and recover the entire
cost thereof from the Other Party, including, without limitation, reasonable
attorneys' fees, disbursements and all amounts paid as a result of such suit,
action, investigation, claim or proceeding or compromise or settlement thereof.

         9. BROKERS. The Sellers and the Purchaser covenant and represent to
each other that they had no dealings with any broker or finder in connection
with this Agreement or the transactions contemplated hereby and no broker,
finder or other person is entitled to receive any broker's commission or
finder's fee or

                                       36
<PAGE>   37
similar compensation in connection with any such transaction. Each of the
parties agrees to defend, indemnify and hold harmless the other from, against,
for and in respect of any and all losses sustained by the other as a result of
any liability or obligation to any broker or finder on the basis of any
arrangement, agreement or acts made by or on behalf of such other party with any
person or persons whatsoever.

                                  May 21, 1996


         FOR VALUE RECEIVED, the undersigned U.S. Alcohol Testing of America,

Warrant No.    5                             22,500 Shares
            --------




         NO SALE, OFFER OR TRANSFER OF THIS WARRANT OR THE SHARES ISSUABLE UPON
         EXERCISE THEREOF SHALL BE MADE UNLESS A REGISTRATION STATEMENT UNDER
         THE SECURITIES ACT OF 1933, AS AMENDED, WITH RESPECT TO SUCH
         TRANSACTION IS THEN IN EFFECT OR THE ISSUER HAS RECEIVED AN OPINION OF
         COUNSEL SATISFACTORY TO IT THAT SUCH TRANSFER DOES NOT REQUIRE
         REGISTRATION UNDER SUCH ACT.


THIS WARRANT WILL BE VOID AFTER 5:00 P.M., NEW YORK TIME, ON MAY 20, 1999

                                     WARRANT
                     TO SUBSCRIBE FOR AND PURCHASE SHARES OF
                                 COMMON STOCK OF

                      U.S. ALCOHOL TESTING OF AMERICA, INC.


         This certifies that, for value received, KIMBERLY ROCHELLE (hereinafter
called the "Holder"), or registered assigns, is entitled, at any time or from
time to time at or after May 21, 1996, with respect to the shares issuable upon
the exercise of this Warrant (the "Commencement Date") and at or before 5:00
P.M., New York time, on May 20, 1999 (the "Expiration Date"), to subscribe for
and purchase an aggregate of 22,500 fully paid and non-assessable shares of the
common stock, $.01 par value (the "Common Stock"), of U.S. Alcohol Testing of
America, Inc., (hereinafter called the "Corporation") at a purchase price of
$3.125 per share (the "Purchase Price"), subject to adjustment as provided in
Section 3 hereof, payable in lawful money of the United States of America, upon
surrender of this Warrant and payment of the Purchase Price to the Corporation
at its principal office (currently 10410 Trademark Street, Rancho Cucamonga,
California 91730) or at such other place as the Corporation may designate by
written notice to the Holder.

1.       Exercise

         The Warrant evidenced hereby may be exercised from time to time, in
whole or in part, from the Commencement Date until the Expiration Date, provided
that in no event may any fractional share of the Common Stock be issued. In the
event that a fractional share would otherwise be issued as a result of any
adjustment made pursuant to Section 3 hereof or otherwise, payment for such
fractional share shall be made on the basis of the Market Price on the date of
exercise. For the purpose of this Section 1, the term "Market Price" shall mean
(a) if the Common Stock is traded on a national securities exchange or on the
National Association of Securities Dealers Automated Quotation ("NASDAQ")
System, the closing sales price (or, if no sales on that day, the high bid
price) or (b) if the Common Stock is not traded as provided in subsection (a),
the closing bid price as reported in the OTC Bulletin Board of the National

<PAGE>   48
Association of Securities Dealers, Inc. (the "NASD") or in the pink sheets by
the National Quotation Bureau, Inc.

         Upon any exercise of the Warrant evidenced hereby, the form of election
to purchase set forth as Exhibit A hereto shall be properly completed, executed
and delivered to the Corporation, together with full payment to the Corporation
of the Purchase Price for the shares as to which the Warrant is exercised by
certified check or bank draft. In the event that there is only a partial
exercise of the Warrant evidenced hereby, there shall be issued to the Holder a
new Warrant Certificate, in all respects similar to this Warrant Certificate,
evidencing the number of shares of the Common Stock still available for
exercise.

         Upon receipt of full payment and properly completed documentation, the
Corporation shall then cause the Transfer Agent for the Common Stock to issue
fully paid and nonassessable shares of the Common Stock as are represented by
the exercise.

         If this Warrant shall be surrendered upon exercise within any period
during which the transfer books for the Common Stock are closed for any purpose,
the Corporation shall not be required to make delivery of certificates for
shares of the Common Stock until the date of the reopening of said transfer
books.

2.       Expiration Date

         The Warrant evidenced hereby may not be exercised before the
Commencement Date or after the Expiration Date with respect to the shares of the
Common Stock as to which the Warrant may be exercised and, to the extent not
exercised by the Expiration Date, the Warrant evidenced hereby shall become
void.

3.       Adjustments

         Subject to the provisions of this Section 3, the Purchase Price and the
shares of the Common Stock as to which the Warrant may be exercised shall be
subject to adjustment from time to time as hereinafter set forth:

                   (a) If at any time, or from time to time, the Corporation
shall, by subdivision, consolidation, or reclassification of shares, or
otherwise, change as a whole the outstanding shares of the Common Stock into a
different number or class of shares, the number and class of shares so changed
shall replace the shares outstanding immediately prior to such change and the
Purchase Price and the number of shares purchasable under this Warrant
immediately prior to the date on which such change shall become effective shall
be proportionately adjusted.

                  (b) Irrespective of any adjustments or change in the Purchase
Price or the number of securities actually purchasable under this Warrant, this
Warrant may continue to express the exercise price and the number of securities
purchasable thereunder as the Purchase

                                        2
<PAGE>   49
Price and the number of securities purchasable were expressed in this Warrant
when initially issued.

                  (c) If at any time while this Warrant is outstanding, the
Corporation shall consolidate with, or merge into, another corporation, firm or
entity, or otherwise enter into a form of business combination, the Holder of
this Warrant shall thereafter be entitled upon exercise thereof to purchase,
with respect to each security purchasable thereunder immediately prior to the
date on which such consolidation or merger or other form of business combination
shall become effective, the securities or property to which a holder of one such
security would have been entitled upon such consolidation or merger or other
form of business combination, without any change in, or payment in addition to,
the Purchase Price in effect immediately prior to such consolidation or merger
or other form of business combination, and the Corporation shall take such steps
in connection with such consolidation or merger or other form of business
combination as may be necessary to assure that all this provisions of this
Warrant shall thereafter be applicable, as nearly as reasonably may be, in
relation to any securities or property thereafter deliverable upon the exercise
of this Warrant.

                   (d) The Board of Directors of the Corporation, in its
discretion, may, at any time during the exercise period of this Warrant, extend
the exercise period or reduce the Purchase Price for this Warrant.

                   (e) Upon the happening of any event requiring the adjustment
of the exercise price hereunder, the Corporation shall forthwith give written
notice thereof to the Holder of this Warrant stating the adjusted Purchase Price
and the adjusted number of securities purchasable upon the exercise thereof
resulting from such event and setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based. The certificate
of the Corporation's independent public accountants shall be conclusive evidence
of the correctness of any computation made hereunder.

4.       Notice to Holder

                   Nothing contained herein shall be construed as conferring
upon the Holder the right to vote or to consent or to receive notice as a
stockholder in respect of the meetings of stockholders for the election of
directors of the Corporation or any other matter, or any other rights whatsoever
as a stockholder of the Corporation; provided, however, that in the event that:

                  (a) the Corporation shall take action to make any
distribution (other than cash dividends payable out of earnings or earned
surplus) on the Common Stock;

                  (b) the Corporation shall take action to offer for
subscription pro rata to the holders of the Common Stock any additional shares
of stock of any class or other rights or securities convertible into the Common
Stock;

                                        3
<PAGE>   50
                   (c) the Corporation shall take action to accomplish any
capital reorganization, or reclassification of the capital stock of the
Corporation (other than a change in par value, or a change from par value to no
par value, or a change from no par value to par value, or a subdivision or
combination of the Common Stock), or a consolidation or merger of the
Corporation into, or a sale of all or substantially all of its assets to,
another corporation; or

                   (d) the Corporation shall take action looking to a voluntary
dissolution, liquidation or winding up of the Corporation;

then, in any one or more of such cases, the Corporation shall, (x) at least 10
days prior to the date on which the books of the Corporation shall close or a
record date shall be taken for such distribution or subscription rights or for
determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up, cause notice thereof to be sent to the Holder at the address
appearing on the Warrant register of the Corporation and, (y) in the case of any
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, cause at least 10 days' prior written notice of the
date when the same shall take place to be given to the Holder in the same
manner. Such notice in accordance with the foregoing clause (x) shall also
specify, in the case of any such distribution or subscription rights, the date
on which the holders of the Common Stock shall be entitled thereto, and such
notice in accordance with the foregoing clause (y) shall also specify the date
on which the holders of the Common Stock shall be entitled to exchange their
shares of the Common Stock for securities or other property deliverable upon
such reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation or winding up, as the case may be. Failure to give such notice or
any defect therein shall not affect the legality or validity of any of the
matters set forth in this Section 4 inclusive.

5.       Transfers and Exchanges

         The Corporation shall transfer, from time to time, this Warrant upon
the books to be maintained by the Corporation for that purpose, upon surrender
thereof for transfer properly endorsed or accompanied by appropriate
instructions for transfer. Upon any such transfer, a new Warrant shall be issued
to the transferee and the surrendered Warrant shall be cancelled by the
Corporation. If this Warrant is so cancelled it shall be delivered to the
Corporation upon request. This Warrant may be exchanged at the option of the
holder thereof, when surrendered at the office of the Corporation, for another
Warrant, or other Warrants of different denominations, of like tenor and
representing in the aggregate the rights to purchase a like number of shares.
Anything in this Section 5 to the contrary notwithstanding, no transfer shall be
made if such transfer would violate Section 5 of the Securities Act of 1933, as
amended.

6.       Payment of Taxes

         The Corporation will pay any documentary stamp taxes attributable to
the initial issuance of the Common Stock issuable upon the exercise of this
Warrant; provided, however, that the Corporation shall not be required to pay
any tax or taxes which may be payable in respect of

                                        4
<PAGE>   51
any transfer involved in the issue or delivery of any certificates for the
Common Stock in a name other than that of the registered holder of this Warrant
in respect of which such shares are issued, and in such case the Corporation
shall not be required to issue or deliver any certificates for the Common Stock
or any Warrant for remaining shares until the person requesting the same has
paid to the Corporation the amount of such tax or has established to the
Corporation's satisfaction that such tax has been paid.

7.       Mutilated or Missing Warrants

         In case that this Warrant shall be mutilated, lost, stolen or
destroyed, the Corporation may in its discretion issue and deliver in exchange
and substitution for, and upon cancellation of, the mutilated Warrant, or in
lieu of, and in substitution for, the Warrant lost, stolen or destroyed, a new
Warrant of like tenor and representing an equivalent right or interest, but only
upon receipt of evidence satisfactory to the Corporation of such loss, theft or
destruction of such Warrant. Applicants for such substitute Warrant shall also
comply with such other reasonable regulations and pay such reasonable charges as
the Corporation may prescribe.

8.       Reserve

         The Corporation covenants and agrees that, from time to time, there
will be authorized and available for delivery a sufficient number of its shares
of the Common Stock or other securities into which this Warrant is then
exercisable to permit the exercise of all of this Warrant at the time
outstanding as and when the certificates shall, from time to time, be
deliverable in accordance with Section 1 hereof. In the event that there are
insufficient shares or other securities for such purpose, the Corporation shall
use its best efforts to seek stockholder approval for an Amendment to the
Corporation's Certificate of Incorporation and/or to take such other action as
is necessary or appropriate to cause such shares or other securities to be
authorized.

9.       Governing Law

         The Warrant evidenced hereby shall be construed and enforced in
accordance with the laws of the State of Delaware applicable to contracts made
and to be performed in that State, without giving effect to any principles of
conflicts of laws.

         IN WITNESS WHEREOF, U.S. Alcohol Testing of America, Inc. has caused
this Warrant to be signed manually by a duly authorized officer of the
Corporation.

                                        3
<PAGE>   58
created hereby in the Collateral constitutes continuing collateral security for
all of the following obligations (the "Obligations"): the prompt payment by the
Grantor, as and when due and payable, of all amounts from time to time owing by
the Grantor to the Secured Parties under the Notes.

         SECTION 4.  REPRESENTATIONS AND WARRANTIES.  The Grantor
represents and warrants as follows:

              (a) The Grantor (i) is a corporation duly organized, validly
existing and in good standing under the laws of the state of Delaware, and (ii)
has all requisite power and authority to execute, deliver and perform this
Agreement.

              (b) The execution, delivery and performance by the Grantor of this
Agreement (i) have been duly authorized by all necessary corporate action, (ii)
do not and will not contravene its charter or by-laws, law or any contractual
restriction binding or affecting the Grantor or any of its properties, and (iii)
do not and will not result in or require the creation of any lien, security
interest or other charge or encumbrance upon or with respect to any of its
properties.

              (c) This Agreement is a legal, valid and binding obligation of the
Grantor, enforceable against the Grantor in accordance with its terms except as
may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or other similar laws and general equity principles affecting the enforcement of
creditors' rights generally.

              (d) The Grantor is and will be at all times the owner of the
Collateral free and clear of any lien, security interest or other charge or
encumbrance, except for (i) the security interest created by this Agreement,

hereto and (iii) any purchase money security interest granted by the Grantor

have been filed in favor of the Secured Parties relating to this Agreement, and
(ii) such as may have been filed to perfect or protect any security interest or
encumbrance described in Schedule I hereto. The filing of UCC-1 Financing
Statements in the filing offices set forth on Schedule II is necessary to
perfect the security interest granted hereunder in the Collateral.

              (e) The exercise by the Secured Parties of any of their rights and
remedies hereunder will not contravene any law or any contractual restriction
binding or affecting the Grantor or any of its properties and will not result in
or require the creation of any lien, security interest or other charge or
encumbrance upon or

                                        4
<PAGE>   59
with respect to any of its properties.

         SECTION 5. COVENANTS AS TO THE COLLATERAL. So long as any of the
Obligations shall remain outstanding, unless the Secured Parties shall otherwise
consent in writing:

              (a) Further Assurances. The Grantor will at its expense, at any
time and from time to time, promptly execute and deliver all further instruments
and documents and take all further action that may be necessary or desirable or
that the Secured Parties may request in order (i) to perfect the security
interest purported to be created hereby, (ii) to enable the Secured Parties to
exercise and enforce their rights and remedies hereunder in respect of the
Collateral, or (iii) to effect otherwise the purposes of this Agreement.

              (b) Transfers and Other Liens. The Grantor will not (i) sell,
assign (by operation of law or otherwise), exchange or otherwise dispose of any
of the Collateral (except for sales of Inventory in the ordinary course of
business), or (ii) create or suffer to exist any lien, security interest or
other charge or encumbrance upon or with respect to any Collateral, except for
(A) the security interest created hereby, (B) the security interests and other
encumbrances described in Schedule I hereto and (C) purchase money security
interests granted by the Grantor in Equipment acquired after the date hereof.

         SECTION 6.  ADDITIONAL PROVISIONS CONCERNING THE COLLATERAL.

              The Grantor hereby authorizes the Secured Parties to file, without
the signature of the Grantor where permitted by law, one or more financing or
continuation statements, and amendments thereto, relating to the Collateral
which the Secured Parties may deem necessary or desirable.

         SECTION 7.  REMEDIES UPON DEFAULT.  If any Event of Default
shall have occurred and be continuing:

              (a) The Secured Parties may exercise in respect of the Collateral,
in addition to other rights and remedies provided for herein or otherwise
available to it, all of the rights and remedies of a secured party on default
under the Code (whether or not the Code applies to the affected Collateral), and
may also (i) require the Grantor to, and the Grantor hereby agrees that it will
at its expense and upon request of the Secured Parties forthwith assemble all or
part of the Collateral as directed by the Secured Parties and make it available
to the Secured Parties at a place to be designated by the Secured Parties which
is reasonably convenient to both parties, and (ii) without notice except as
specified below, sell the Collateral or any part thereof in one or more parcels
at public or private sale, at any of the Secured Parties's offices or elsewhere,
for cash, on credit or for future delivery, and at such

                                        5
<PAGE>   60
price or prices and upon such other terms as the Secured Parties may deem
commercially reasonable. The Grantor agrees that, to the extent notice of sale
shall be required by law, at least 10 days notice to the Grantor of the time and
place of any public sale or the time after which any private sale is to be made
shall constitute reasonable notification. The Secured Parties shall not be
obligated to make any sale of Collateral regardless of notice of sale having
been given. The Secured Parties may adjourn any public or private sale from time
to time by announcement at the time and place fixed therefor, and such sale may,
without further notice, be made at the time and place to which it was so
adjourned.

              (b) All cash proceeds received by the Secured Parties in respect
of any sale of, collection from, or other realization upon, all or any part of
the Collateral shall be applied by the Secured Parties (after payment of any
amounts payable to the Secured Parties pursuant to Section 8 hereof) against,
all of the Obligations as is set forth in Section 7(d) below. Any surplus of
such cash or cash proceeds held by the Secured Parties and remaining after
payment in full of all of the Obligations shall be paid over to the Grantor or
to such person as may be lawfully entitled to receive such surplus.

              (c) In the event that the proceeds of any such sale, collection or
realization are insufficient to pay all amounts to which the Secured Parties are
legally entitled, the Grantor shall be liable for the deficiency, together with
interest thereon at the rate specified in the Notes, together with the costs of
collection and the reasonable fees and expenses of any attorneys employed by the
Secured Parties to collect such deficiency.

              (d) All cash proceeds received by the Secured Parties in respect
of any sale of the Collateral shall be applied by the Secured Parties (after
payment of any amounts payable to the Secured Parties pursuant to Section 8
hereof) against the Obligations on a pro rata basis based upon the ratio that
the original principal amount of each Secured Parties Note bears to the
aggregate original principal amount of all of the Notes. All decisions to be
made by the Secured Parties under this Agreement with respect to the Collateral
and the security interest granted hereunder, including, without limitation,
whether to exercise the Secured Parties' rights upon an Event of Default, shall
be made solely by Robert Stutman, in his sole discretion, on behalf of all of
the Secured Parties. In the event Robert Stutman is deceased or incompetent, all
decisions shall be made by Brian Stutman, including, under Section 10(a) hereof.

         SECTION 8.  INDEMNITY AND EXPENSES.

              (a) The Grantor agrees to indemnify the Secured Parties from and
against any and all claims, losses and liabilities growing out of or resulting
from this Agreement (including, without

                                        6
<PAGE>   61
limitation, enforcement of this Agreement), except claims, losses or liabilities
resulting solely and directly from the Secured Parties' gross negligence or
willful misconduct.

              (b) The Grantor will, upon demand, pay to the Secured Parties the
amount of any and all costs and expenses, including the reasonable fees and
disbursements of the Secured Parties' counsel and of any experts and agents,
which the Secured Parties may incur in connection with the exercise or
enforcement of any of the rights of the Secured Parties hereunder.

         SECTION 9.  NOTICES, ETC.

              All notices and other communications provided for hereunder shall
be in writing and shall be sent by overnight courier service or hand delivered,
if to the Grantor, to it at: 10410 Trademark Street Rancho Cucamonga, California
91730; if to the Secured Parties, to them at: c/o Edward D. Feldstein, Esq.,
Roberts, Carroll, Feldstein & Peirce, 10 Weybosset Street, Providence, Rhode
Island 02903-2808. All such notices and other communications shall be effective

first, (ii) if sent by overnight courier, one business day after sending; (iii)
if hand delivered, upon delivery, provided same is on a business day and, if
not, on the next business day.

         SECTION 10.  MISCELLANEOUS.

              (a) No amendment of any provision of this Agreement shall be
effective unless it is in writing and signed by the Grantor and Robert Stutman,
and no waiver of any provision of this Agreement, and no consent to any
departure by the Grantor therefrom, shall be effective unless it is in writing
and signed by Robert Stutman, and then such waiver or consent shall be effective
only in the specific instance and for the specific purpose for which given.

              (b) No failure on the part of the Secured Parties to exercise, and
no delay in exercising, any right hereunder or under the Notes shall operate as
a waiver thereof; nor shall any single or partial exercise thereof preclude any
other or further exercise of any other right hereunder or under the Notes. The
rights and remedies of the Secured Parties provided herein and in the Notes are
cumulative and are in addition to, and not exclusive of, any rights or remedies
provided by law. The rights of the Secured Parties under this Agreement and the
Notes are not conditional or contingent on any attempt by the Secured Parties to
exercise any of their rights against any other person.

              (c) Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or

                                        7
<PAGE>   62
unenforceability without invalidating the remaining portions hereof or thereof
or affecting the validity or enforceability of such provision in any other
jurisdiction.

              (d) This Agreement shall create a continuing security interest in
the Collateral and shall (i) remain in full force and effect until the payment
in full of the Obligations, (ii) be binding on and inure to the benefit of the
Grantor and the Secured Parties and their successors and assigns.

              (e) Upon the satisfaction in full of the Obligations: (i) this
Agreement and the security interest created hereby shall terminate and all
rights to the Collateral shall revert to the Grantor, and (ii) the Secured
Parties will, upon the Grantor's request and at the Grantor's expense, (A)
return to the Grantor such of the Collateral as shall not have been sold or
otherwise disposed of or applied pursuant to the terms hereof, and (B) execute
and deliver to the Grantor such documents as the Grantor shall reasonably
request to evidence such termination.

              (f) This Agreement shall be governed by, and construed and
interpreted in accordance with, the internal laws of the State of California
applicable to contracts made and to be performed herein without consideration as
to choice of law.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be

                         REGISTRATION RIGHTS AGREEMENT


         THIS REGISTRATION RIGHTS AGREEMENT is made as of the 21st day of May
1996, by and between U.S. Alcohol Testing of America, Inc., a Delaware
corporation (the "Company), Robert Stutman, Brian Stutman, Michael Rochelle,
Kimberly Rochelle and Sandra DeBow (collectively the "Sellers").


                                    RECITALS

         WHEREAS, the Company and the Sellers are parties to a Stock Purchase
Agreement, dated May 21, 1996 (the "Stock Purchase Agreement"), pursuant to
which the Company purchased from the Sellers all of their shares of common stock
of Robert Stutman Associates, Inc. (the "RSA Shares");

         WHEREAS, a portion of the purchase price for the RSA Shares consists of
500,000 shares (the "Purchase Price Shares") of the Common Stock of the Company,
$.001 par value (the "Common Stock") and warrants (the "Warrants") to purchase
900,000 shares of the Common Stock (the share issuable upon the exercise of the
Warrants are hereinafter referred to as the "Underlying Shares");

         WHEREAS, the Sellers are holders of Warrants and Purchase Price Shares
as is set forth in Exhibit A annexed hereto;

         WHEREAS, each of the Sellers and the Company hereby agree that this
Agreement shall govern the rights of the Sellers to cause the Company to
register his Purchase Price Shares and Underlying Shares.

         NOW, THEREFORE, the parties hereby agrees as follows:

         1. Registration Rights. The Company covenants and agrees as follows:

                  1.1  Definitions.  For purposes of this Agreement:

                        (a) The term "register", "registered", and
"registration" refer to a registration affected by preparing and filing a
registration statement or similar document in compliance with the Securities Act
of 1933, as amended (the "Act") and the use, by the Company, of its best efforts
to cause the declaration or ordering of effectiveness of such registration
statement or document.

                        (b) The term "Registrable Securities" means (1) the
Purchase Price Shares and the Underlying Shares, and (2) any shares of the
Common Stock of the Company issued as (or issuable upon the conversion or
exercise of any warrant, right or other security which is issued as) a dividend
or other distribution with respect

<PAGE>   64
to, or in exchange for or in replacement of, the Purchase Price Shares and
Underlying Shares, excluding in all cases, however, any Registrable Securities
sold by a person in a transaction in which his, her or its rights under this
Section 1 are not assigned.

                        (c) The number of shares of "Registrable Securities then
outstanding" shall be determined by the number of shares of the Common Stock
outstanding which are, and the number of shares of the Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities.

                        (d) The term "Holder" means any person owning or having
the right to acquire Registrable Securities or any assignee thereof in
accordance with Section 1.10 hereof.

                   1.2 Company Registration. If, at any time after the date of
the issuance of the Purchase Price Shares and the Warrants (but without any
obligation to do so), the Company proposes to register (including for this
purpose a registration effected by the Company for stockholders other than the
Holders) any of its stock or other securities under the Act in connection with
the public offering of such securities solely for cash (other than a
registration statement or Form S-8 or Form S-4 or any successor form thereto),
the Company shall, at such time, promptly give each Holder written notice of
such registration. The Company shall, subject to the provisions of Section 1.8,
cause to be registered under the Act all of the Registrable Securities owned by
each Holder to be registered under the Act under the proposed registration
statement unless within twenty (20) days after the mailing of the notice by the
Company a Holder gives the Company written notice in accordance with Section 2.5
that he does not want all or a portion of the Registrable Securities to be so
registered.

                        In the event that the Company does not by September 1,
1996 register (including for this purpose a registration effected by the Company
for stockholders other than the Holders) any of its stock or other securities
under the Act in connection with the public offering of such securities solely
for cash (other than a registration statement or Form S-8 or Form S-4 or any
successor form thereto), the Holder may demand that the Company register under
the Act, all or a portion of the Registrable Securities owned by each such
Holder. Such demand may only be made one time in the aggregate for all of the
Holders. Such demand may only be made if Robert Stutman consents thereto in
writing.

                   1.3 Obligations of the Company. Whenever undertaking under
this Section 1 to effect the registration of any Registrable Securities, the
Company shall, as expeditiously as reasonably possible:

                        (a) Prepare and file with the Commission a registration
statement with respect to such Registrable Securities

                                        2
<PAGE>   65
and use its best efforts to cause such registration statement to become
effective and keep such registration statement effective for one hundred eighty
(180) days or such shorter period as requested by the Holders of a majority of
the Registrable Securities registered thereunder.

                        (b) Prepare and file with the Commission such amendments
and supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply with
the provisions of the Act with respect to the disposition of all securities
covered by such registration statement.

                        (c) Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

                        (d) Use its best efforts to register and quality the
securities covered by such registration statement under such other securities or
Blue Sky laws of the States of Florida and New York and the Commonwealth of
Massachusetts, provided that the Company shall not be required in connection
therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions.

                        (e) In the event of any underwritten public offering,
enter into and perform its obligations under an underwriting agreement, in usual
and customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                        (f) Notify each Holder of the Registrable Securities
covered by such registration statement at any time when a prospectus relating
thereto is required to be delivered under the Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

                        (g) Furnish, at the request of any Holder requesting
registration of Registrable Securities pursuant to this Section 1, on the date
that such Registrable Securities are delivered to the underwriters for sale in
connection with a registration pursuant to this Section 1, if such securities
are being sold through underwriters, or, if such securities are not being sold
through underwriters, on the date that the registration statement with respect
to such securities becomes effective, (i) an

                                        3
<PAGE>   66
opinion, dated such date, of the counsel representing the Company for the
purposes of such registration, in form and substance as is customarily given to
underwriters in an underwritten public offering, addressed to the underwriters,
if any, and to the Holders requesting registration of the Registrable Securities
and (ii) a letter dated such date, from the independent certified public
accountants of the Company, in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten
public offering, addressed to the underwriters, if any, and to the Holders
requesting registration of the Registrable Securities.

                   1.4 Furnish Information. It shall be a condition precedent to
the obligations of the Company to take any action pursuant to this Section 1
with respect to the Registrable Securities of any selling Holder that such
Holder shall furnish to the Company such information regarding itself, the
Registrable Securities held by it, and the intended method of disposition of
such securities as shall be required to effect the registration of such Holder's
Registrable Securities.

                   1.5 Expenses of Registration. The Company shall bear and pay
all expenses incurred in connection with any registration, filing or
qualification, to the extent set forth in Section 1.3, of the Registrable
Securities with respect to the first registration pursuant to Section 1.2 for
each Holder (which right may be assigned as provided in Section 1.10), including
(without limitation) all registration, filing, and qualification fees, printers
and accounting fees relating or apportionable thereto, but excluding
underwriting discounts and commissions relating to Registrable Securities.

                   1.6 Underwriting Requirements. In connection with any
offering involving an underwriting of shares of the Company's capital stock, the
Company shall not be required under Section 1.2 to include any of the Holders'
securities in such underwriting unless they accept the terms of the underwriting
as agreed upon between the Company and the underwriters selected by it (or by
other persons entitled to select the underwriters), and then only in such
quantity as the underwriters determine in their sole discretion will not,
jeopardize the success of the offering by the Company. If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters determine in their sole
discretion will not jeopardize the success of the offering (the securities so
included to be apportioned pro rata among the selling shareholders according to
the total amount of securities entitled to be included therein

                                        4
<PAGE>   67
owned by each selling shareholder or in such other proportions as shall mutually
be agreed to by such selling shareholders). For purposes of the preceding
parenthetical concerning apportionment, for any selling shareholder which is a
holder of Registrable Securities and which is a partnership or corporation, the
partners, retired partners and shareholders of such holder, or the estates and
family members of any such partners and retired partners and any trusts for the
benefit of any of the foregoing persons shall be deemed to be a single "selling
shareholder", and any pro rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder", as defined in this sentence.

                   1.7 Delay of Registration. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

                   1.8 Indemnification. In the event any Registrable Securities
are included in a registration statement under this Section 1:

                        (a) To the extent permitted by law, the Company will
indemnify and hold harmless each Holder who is not a director or executive
officer of the Company, any underwriter (as defined in the Act) for such Holder
and each person, if any, who controls such Holder or underwriter within the
meaning of the Act or the Securities Exchange Act of 1934, as amended (the "1934
Act"), against any losses, claims, damages, or liabilities (joint or several) to
which they may become subject under the Act, or the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"): (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein not misleading, or (iii) any
violation or alleged violation by the Company of the Act, the 1934 Act, any
state securities law or any rule or regulation promulgated under the Act, or the
1934 Act or any state securities law; and the Company will pay to each such
Holder, underwriter or controlling person, as incurred, any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided, however,
that the indemnity agreement contained in this subsection 1.8(a) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability, or
action if such

                                        5
<PAGE>   68
settlement is effected without the consent of the Company, nor shall the Company
be liable in any such case for any such loss, claim, damage, liability, or
action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by any such Holder,
underwriter or controlling person.

                        (b) To the extent permitted by law, each selling Holder
will indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Act, any underwriter, any other
Holder selling securities in such registration statement and any controlling
person of any such underwriter or other Holder, against any losses, claims,
damages, or liabilities (joint or several) to which any of the foregoing persons
may become subject, under the Act, or the 1934 Act or other federal or state
law, insofar as such losses, claims, damage,s or liabilities (or actions in
respect thereto) arise out of or are based upon any violation, in each case to
the extent (and only to the extent) that such Violation occurs in reliance upon
and in conformity with written information furnished by such Holder expressly
for use in connection with such registration; and each such Holder will pay, as
incurred, any legal or other expenses reasonably incurred by any person intended
to be indemnified pursuant to this subsection 1.8(b), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
1.8(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Holder.

                        (c) Promptly after receipt by an indemnified party under
this Section 1.8 of notice of the commencement of any action (including any
governmental action) such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.7, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if

                                        6
<PAGE>   69
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.8, but the omission so to deliver written notice to the indemnifying party
will not relieve it of any liability that it may have to any indemnified party
otherwise than under this Section 1.8.

                        (d) If the indemnification provided for in this Section
1.8 is held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any loss, liability, claim, damage, or expense
referred to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable by
such indemnified party as a result of such loss, liability, claim, damage, or
expense in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

                        (e) Notwithstanding the foregoing, to the extent that
the provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

                        (f) The obligations of the Company and Holders under
this Section 1.8 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

                   1.9 Reports Under Securities Exchange Act of 1934. With a
view to making available to the Holders the benefits of Rule 144 promulgated
under the Act and any other rule or regulation of the Commission that may at any
time permit a Holder to sell securities of the Company to the public without
registration, the Company agrees to:

                        (a) make and keep public information available, as those
terms are understood and defined in Commission Rule 144 promulgated under the
Act;

                                        7
<PAGE>   70
                        (b) file with the Commission in a timely manner all
reports and other documents required of the Company under the Act and the 1934
Act; and

                        (c) furnish to any Holder, so long as the Holder owns
any Registrable Securities, forthwith upon request (i) a written statement by
the Company that it has complied with the reporting requirements of Rule 144
promulgated under the Act and the 1934 Act (at any time after it has become
subject to such reporting requirements), (ii) a copy of the most recent annual
and quarterly reports of the Company and such other report and documents so
filed by the Company, and (iii) such other information as may be reasonably
requested in availing any Holder of any rule or regulation of the Commission
which permits the selling of any such securities without registration.

                   1.10 Assignment of Registration Rights. The rights to cause
the Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities, provided the Company is, within a reasonable time
after such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act.

                   1.11 Termination of Registration Rights. No Holder shall be
entitled to exercise any right provided for in this Section 1 after May 20,
2001; provided that at least two registration statements of the Company have
been declared effective prior to such date with respect to which the Holders are
entitled to exercise the rights provided for in this Section 1.

         2.  Miscellaneous.

                   2.1 Successors and Assigns. Except as otherwise provided
herein, the terms and conditions of this Agreement shall inure to the benefit of
and be binding upon the respective successors and assigns of the parties
(including transferees of the Warrants, the Purchase Price Shares or any shares
issued or issuable upon the exercise of the Warrants). Nothing in this
Agreement, express or implied, is intended to confer upon any party other than
the parties hereto or their respective successors and assigns any rights,
remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement.

                   2.2 Governing Law. This Agreement shall be governed by and
construed under the laws of the State of California.

<PAGE>   71
                   2.3 Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                   2.4 Titles and Subtitles. The titles and subtitles used in
this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

                   2.5 Notices. Unless otherwise provided, any notice required

to be notified at the address indicated for such party on the signature page
hereof, or at such other address as such party may designate by ten (1) days
advance written notice to the other parties.

                   2.6 Expenses. If any action at law or in equity is necessary
to enforce or interpret the terms of this Agreement, the prevailing party shall
be entitled to reasonable attorneys' fees, costs and necessary disbursements in
addition to any other relief to which such party may be entitled.

                   2.7 Amendments and Waivers. The Company and Holders of 50% of
the Purchase Price Shares, the Warrants and the Underlying Shares can agree to
an amendment of, or a waiver to, the terms of this Agreement.

                   2.8 Severability. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, such provision shall be
excluded from this Agreement and the balance of the Agreement shall be
interpreted as if such provision were so excluded and shall be enforceable in
accordance with its terms.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first above written.

("RSA");

                   WHEREAS, the Executive was the majority shareholder of RSA
and the President of RSA;

                   WHEREAS, a condition of the Company's agreeing to purchase

                   WHEREAS, since April 17, 1996, the Executive has been
employed on an at-will basis by the Company as its Chief Executive Officer;

                   WHEREAS, a condition subsequent to the Executive accepting
the Company's offer of employment was that the Company and the Executive enter
into this Severance Agreement which provides for the Executive's right to

and

                   WHEREAS, the compensation to be paid to the Executive by the

<PAGE>   2
                        (iv) bonuses in respect of subsequent fiscal years shall
be determined by the Company's Board of Directors or the Compensation Committee.

                   NOW, THEREFORE, in consideration of the premises and the
mutual agreements contained herein, the Company and the Executive hereby agree
as follows:

                   1. COMPANY'S RIGHT TO TERMINATE. Subject to the Company
fulfilling its obligations to the Executive relating to compensation and
benefits during the term of this Agreement, the Executive agrees that he will
not voluntarily leave the employ of the Company and will continue to perform the
Executive's regular duties as Chief Executive Officer of the Company.
Notwithstanding the foregoing, the Company may terminate the Executive's
employment at any time, subject to providing the benefits hereinafter specified
in accordance with the terms hereof.

                   2. TERMINATION OF EMPLOYMENT. The termination of the
Executive as an employee of the Company for Disability or Cause shall be on the
following terms and conditions:

                        (i) Disability.

                            Termination by the Company of the Executive's
employment based on "Disability" shall mean termination (a) because of the
Executive's inability to perform his duties with the Company on a full time
basis for four consecutive months or 180 days out of any twelve-month period, as
a result of the Executive's incapacity due to physical or mental illness; or (b)
as a result of the Executive being certified incompetent by a court of competent
jurisdiction and which appeals from such certification have expired.

                        (ii) Cause.

                            Termination by the Company of the Executive's
employment for "Cause" shall mean termination because of: (a) the Executive's
conviction of a felony; (b) any action by the Executive involving dishonesty,
fraud or gross or wilful misconduct in connection with his employment with the
Company; (c) the Executive's gross negligence in the performance of his duties
and obligations hereunder or habitual neglect of his duties; (d) the Executive's
substance abuse, including, without limitation, chronic alcoholism or drug
addiction; (e) the Executive's intentional refusal or failure to perform his
duties as the Chief Executive Officer of the Company, including, without
limitation, the intentional disregard of a lawful directive by the Board of
Directors of the Company or any committee thereof; (f) intentional conduct on
the part of the Executive which is knowingly detrimental to the best interests
of the Company; or (g) the Executive's

                                        2
<PAGE>   3
failure to perform in a competent manner his duties as Chief
Executive Officer of the Company.

                        (iii) Notice of Termination.

                            Any purported termination by the Company pursuant to
Section (i) or (ii) above or for any other reason shall be communicated by
written Notice of Termination to the Executive from the President of the Company
at the direction of the Board of Directors of the Company. For purposes of this
Agreement, a "Notice of Termination" shall mean a notice which shall indicate
that it is without cause or the specific termination provision in this Agreement
relied upon and shall set forth in reasonable detail the facts and circumstances
claimed to provide a basis for termination of the Executive's employment under
the provision so indicated.

                        (iv) Date of Termination.

                            "Date of Termination" shall mean (a) if the
Executive's employment is terminated for Disability, the date specified in the
Notice of Termination, (b) if Executive's employment is terminated for Cause,
the date specified in the Notice of Termination, (c) if the Executive's
employment is terminated for death, the date of death, and (d) if the
Executive's employment is terminated, without cause, the date on which a Notice
of Termination is given.

                   3. CERTAIN BENEFITS UPON TERMINATION. (i) If the Executive's
employment is terminated by the Company other than for Cause, Disability or
death, then the Executive shall be entitled to the benefits provided below:

                      (a) the Company shall pay the Executive his full Base
Salary through the Date of Termination at the rate in effect at the time the
Notice of Termination is given plus credit for any vacation earned but not taken
and the amount, if any, of any bonus for a past fiscal year which has not yet
been awarded or paid to the Executive.

                      (b) in lieu of any further salary, bonuses or benefits
payments to the Executive for periods subsequent to the Date of Termination, the
Company shall pay as severance pay to the Executive on the 30th day following
the Date of Termination a lump sum amount equal to the total amount of the Base
Salary that would have been paid to the Executive had he not been terminated
during the period commencing on the Date of Termination and ending on May 20,
1999;

                      (c) the Company shall maintain in full force and effect,

medical, health and accident, and disability plans, programs or arrangements in
which the Executive was entitled to participate immediately prior to the Date of
Termination, provided that the Executive's continued participation is possible
under the general terms and provisions of such plans and programs. In the event
that the Executive's participation in any such plan or program is barred, the
Company shall arrange to provide the Executive with benefits substantially
similar to those which the Executive was entitled to receive under such plans
and programs;

                        (ii) If the Executive's employment is terminated for
Disability under Section 2(i)(b) the Executive shall be entitled to the benefits
provided below:

                      (a) the Company shall pay the Executive his full Base
Salary through the Date of Termination at the rate in effect at the time the
Notice of Termination is given plus credit for any vacation earned but not taken
and the amount, if any, of any bonus for a past fiscal year which has not yet
been awarded or paid to the Executive;

                      (b) in lieu of any further salary, bonuses or benefits
payments to the Executive for periods subsequent to the Date of Termination, the
Company shall pay as severance pay to the Executive on the 30th day following
the Date of Termination a lump sum amount equal to the annual Base Salary that
would have been paid to the Executive had he not been terminated during the
period commencing on the Date of Termination and ending on the earlier of four
months after the Date of Termination or May 20, 1999;

                      (c) the Company shall maintain in full force and effect,
for the Executive's continued benefit until the earlier of four months after the
Date of Termination and May 20, 1999 his automobile allowance and all life
insurance, medical, health and accident, and disability plans, programs or
arrangements in which the Executive was entitled to participate immediately
prior to the Date of Termination, provided that the Executive's continued
participation is possible under the general terms and provisions of such plans
and programs. In the event that the Executive's participation in any such plan
or program is barred, the Company shall arrange to provide the Executive with
benefits substantially similar to those which the Executive was entitled to

         1. TERMS OF PURCHASE AND SALE.

            1.1 TRANSFER OF ASSETS. Subject to the terms and conditions set
forth in this Agreement, Seller agrees to sell, convey, transfer, assign, and
deliver to Purchaser, and Purchaser agrees to purchase from Seller, all the
assets, properties, and business of Seller of every kind, character, and
description whether tangible, intangible, real, personal, or mixed, and wherever

as "the Assets," including, but not without limitation to, the following:

applications, licenses, royalty rights, deposits, and rights and claims to
refunds and adjustments of any kind.

            1.2 EXCLUDED ASSETS. The Assets shall not include any of the
Seller's cash, cash equivalents and inter-company notes and accounts receivable.

            1.3 PURCHASE PRICE. The purchase price (the "Purchase Price") for
the Assets shall be the assumption of the Assumed Liabiltiies (herein defined)
and $500,000 to be payable at the Closing as follows:

     at the rate of seven percent (7%) per annum, with annual payments of

     first priority security interest in the Purchaser's assets evidenced by a
     Security Agreement and UCC-1 Financing Statement. Seller agrees to and
     shall subordinate its security interest in the collateral to additional
     institutional financing not to exceed $1 million at the request of
     Purchaser provided that such financing is used to finance the Purchaser's
     existing Business, or crumb rubber business and not to guaranty the
     obligations of a third party or finance another type of business. Seller
     agrees to sign additional documents as necessary to implement the
     subordination. Purchaser shall use the additional financing to provide
     working capital to the Business; however, if Purchaser uses the additional
     financing to provide working capital to a crumb rubber business owned by
     the Purchaser, the net sales from the other business shall be added to the
     net sales of the Current Products under subparagraph (c) below for purposes
     of calculating the additional payments to be made under the Secured Note.

     and D, respectively.

     floor tiles and any other products currently manufactured by Seller
     (collectively "Current Products") exceed $1.4 million, an additional
     principal reduction shall be made on an annual basis in a sum equal to
     twelve and one-half percent (12-1/2%) of the net sales of Current Products
     which exceed $1.4 million. A Contract Year shall be each 12-month period
     after the Closing Date commencing on the Closing Date or the anniversary of
     the Closing Date and ending 12 months thereafter. Net Sales shall be
     defined as gross sales less returns, allowances and sales discounts. The

<PAGE>   6

     accountants to make a written determination of the amount of the net sales
     based upon an audit of the Purchaser's net sales. The Purchaser shall cause
     a copy of such written determination to be furnished to each of the parties
     hereto within forty-five (45) days of the end of the Contract Year and such
     determination shall be final and binding upon the parties hereto unless the
     Seller shall have notified the Purchaser in writing of any objections
     thereto within thirty (30) days after the Seller's receipt of such
     determination. Any notice of objection shall specify in reasonable detail
     the items which are being disputed and shall include a summary of the
     reason for such dispute. Any dispute relating to the determination of the
     net sales which cannot be resolved by the parties within thirty (30) days
     after receipt of any such notice of objections shall be referred for
     decision to such internationally recognized firm of independent public
     accountants as shall be mutually agreed upon by the Purchaser and the
     Seller, or failing such agreement, such other internationally recognized
     firm of independent public accountants as shall be selected in accordance
     with the rules of the American Arbitration Association (such firm so agreed
     upon or selected being referred to as the "Disputes Auditor"). A decision
     of the Disputes Auditor with respect to any matter or matters in dispute
     shall be final and binding on the parties hereto (absent fraud, bad faith,
     undue influence or manifest error). The Disputes Auditor shall be required
     to render its decision within thirty (30) days after referral of the
     dispute to it for decision pursuant hereto. The fees of the Disputes
     Auditor shall be borne by the Purchaser, on the one hand, and the Seller,
     on the other hand, in proportion to a separate determination by the
     Disputes Auditor of the relative merits of the Purchaser's and Seller's
     positions in dispute. The additional payment based upon net sales shall be
     made within ten (10) days of the determination of the amount of the net
     sales becoming final.

days of each anniversary of the Closing Date until the Secured Note is paid.

reasonably determines to be related to such claim.

            8.4 DEFENSE. If the facts giving rise to a right to indemnification
arise out of the claim of any third party, the

                                       17
<PAGE>   21
Indemnifying Party may assume the defense thereof, including the employment of
counsel, at its cost and expense. The Indemnified Party shall have the right to
employ counsel separate from counsel employed by the Indemnifying Party in any
such action and to participate therein, but the fees and expenses of such
counsel employed by the Indemnified Party shall be at its expense. The
Indemnifying Party shall not be liable for any settlement of any such claim
effected without its prior written consent. Whether or not the Indemnifying
Party does choose to so defend such claim, all the parties hereto shall
cooperate in the defense thereof and shall furnish such records, information and
testimony, and attend at such conferences, discovery proceedings, hearings,
trials and appeals, as may be reasonably requested in connection therewith. The
Indemnifying Party shall be subrogated to all rights and remedies of the
Indemnified Party to the extent of any indemnifications provided hereunder.

            8.5 SET-OFF. In addition to any rights and remedies available to
Purchaser under this agreement or under applicable law, and not by way of
limitation of any such rights, in the event Seller is obligated to indemnify,
defend and hold Purchaser harmless, Purchaser is hereby irrevocably authorized
by Seller, at any time and from time to time, after 30 days written notice to
Seller, to set off and apply against Purchaser's obligation to make payments to
Seller under the terms of the Secured Note any amount owing to Purchaser in
connection with Seller's obligation to indemnify and hold harmless, and the
exercise of such right by Purchaser shall in no event affect, and each of Seller
and Purchaser shall not be excused from honoring or performing their respective
obligations under this agreement. Purchaser is not entitled to exercise its
right of setoff if Seller is fulfilling its obligation to defend the Seller from
a third-party claim.

            Notwithstanding any to the contrary contained in Section 8.2, the
Indemnified Party shall not have any liability under Section 8.2 unless the
aggregate amount of damages under such Section exceeds $10,000 (in which event
the Indemnifying Party shall have liability, subject to clause (ii) below, for
the total amount of damages thereunder, including the first $10,000) and (ii)
the Indemnifying Party's aggregate liability under Section 8.2 shall not exceed
the Purchase Price paid to the Sellers or which would have been payable to the
Seller had (a) the Indemnifying Party not breached or failed to fulfill in any
material respect any covenant, agreement, or other obligation of the
Indemnifying Party under this Agreement or (B) there not been any inaccuracy in
any material respect in any representation of breach in any material respect of
any warranty of the Indemnifying Party; provided, however; in the event that,
after the Closing, the amount of the Seller's liability under Section 8.2
exceeds the sum of the Purchase Price actually paid to the Seller at the time
such liability is determined, the amount of such excess may only be collected
from the Seller by the Purchaser's set off of such excess amount against future
payments of the Purchase Price. The $10,000 limitation on liability under
Section 8.2 shall not apply to the Purchaser's breach of the payment of the
Secured Note, the

                                       18
<PAGE>   22
Purchaser's failure to pay an Assumed Liability or the Seller's failure to pay a
liability that was not an Assumed Liability.
