SPECIAL PURPOSE STOCK OPTION PLAN

         SECTION 1. Description and Purpose of this Plan. This is the Special
Purpose Stock Option Plan of PIA Merchandising Services, Inc., a Delaware
corporation (the "Company"). This Plan has been created to provide for the
issuance of substitute options ("Substitute Options") to the holders of
outstanding stock options ("SAI Options") granted by SPAR Acquisition, Inc., a
Nevada corporation ("SAI"), as required by the terms of that certain Agreement
and Plan of Merger dated as of February 28, 1999 by and among the Company, SAI
and certain other parties named therein (the "Merger Agreement"). Substitute
Options granted under this Plan will not qualify as incentive stock options
under Section 422 of the Internal Revenue Code of 1986, as amended (the "Code").

         SECTION 2. Issuance of Substitute Options. As required by Section 2.04
of the Merger Agreement, the Company shall, promptly following the Effective
Time (as such term is defined in the Merger Agreement) execute and deliver to
each holder of an SAI Option, against delivery and cancellation of such SAI
Option, a Substitute Option containing substantially the same provisions as the
SAI Option being canceled, including, without limitation, (i) the same per share
exercise price and (ii) providing for the right to purchase such number of
shares of the Company's common stock ("Common Stock") as shall be equal to the
number of shares of SAI's common stock that such holder was entitled to purchase
pursuant to the SAI Option being surrendered (a "Substitute Option Agreement").
The persons receiving Substitute Options under this Plan are hereinafter
referred to as the "Participants.") The Company shall have no obligations to
issue any Substitute Options to any Participant prior to the Effective Time.
This Plan shall terminate immediately upon the termination of the Merger
Agreement in accordance with its terms.

         SECTION 3. Shares Subject to this Plan. The number of shares of Common
Stock in respect of which Substitute Options may be granted under this Plan is
134,114, subject to adjustment as provided in Section 6 hereof. After the
initial grant of Substitute Options as provided in the Merger Agreement, no
further Substitute Options may be granted under this Plan.

         SECTION 4. Administration. This Plan shall be administered by the Board
of Directors of the Company (the "Board"). The Board shall have the exclusive
and binding right to (i) interpret this Plan, (ii) prescribe, amend and rescind
rules relating to this Plan; (iii) authorize any person to execute on behalf of
the Company any instrument required to effectuate the grant of an Substitute
Option; (iv) determine the rights and obligations of Participants under this
Plan; and (v) make all other determinations deemed necessary or advisable for
the administration of this Plan. The good faith interpretation and construction
by the Board of any provision of this Plan or of any Substitute Option shall be
final, conclusive and binding. No member of the Board shall be liable for any
action or determination made in good faith with respect to this Plan or any
Substitute Option.

     SECTION 5. Issuance of Common Stock. The Company's obligation to issue
shares of its Common Stock upon exercise of a Substitute Option by any
Participant is expressly conditioned upon the compliance by the Company with any
registration or other qualification obligations with respect to such shares
under any state or federal law or rulings and regulations of any government
regulatory body and the making of such investment representations or other
representations and undertakings by such Participant (or such Participant's
legal representative, heir or legatee, as the case may be) in order to comply
with the requirements of any exemption from any such registration or other
qualification obligations with respect to such shares which the Company in its
sole discretion shall deem necessary or advisable. Such required representations
and undertakings may include representations and agreements that such
Participant (or such Participant's legal representative, heir or legatee) (i) is
purchasing such shares for investment and not with any present intention of
selling or otherwise disposing of such shares and (ii) agrees to have a legend
placed upon the face and reverse of any certificates evidencing such shares (or,
if applicable, an appropriate data entry made in the ownership records of the
Company) setting forth (A) any representations and undertakings which such
Participant has given to the Company or a reference thereto, and (B) that, prior
to effecting any sale or other disposition of any such shares, such Participant
must furnish to the Company an opinion of counsel,

                                       1
<PAGE>

satisfactory to the Company and its counsel, to the effect that such sale or
disposition will not violate the applicable requirements of state and federal
laws and regulatory agencies; provided, however, that any such legend or data
entry shall be removed when no longer applicable. The Company, during the term
of this Plan, will at all times reserve and keep available, and will use its
reasonable efforts to obtain from any regulatory body having jurisdiction any
requisite authority in order to issue and sell such number of shares of Common
Stock as shall be sufficient to satisfy the requirements of this Plan. The
inability of the Company to obtain, from any regulatory body having
jurisdiction, authority reasonably deemed by the Company's counsel to be
necessary for the lawful issuance and sale of any shares hereunder shall relieve
the Company of any liability in respect of the non-issuance or sale of such
shares as to which such requisite authority shall not have been obtained.

     SECTION 6. Adjustments Upon Capitalization and Corporate Changes. If the
outstanding shares of the Common Stock are changed into, or exchanged for, a
different number or kind of shares or securities of the Company through
reorganization, merger, recapitalization or reclassification, or if the number
of outstanding shares is changed through a stock split, stock dividend, stock
consolidation or like capital adjustment, or if the Company makes a distribution
in partial liquidation or any other comparable extraordinary distribution with
respect to its Common Stock, an appropriate adjustment shall be made by the
Board in the number, kind or exercise price of shares with respect to which
unexercised Substitute Options have been granted; provided, however, that in no
event shall the exercise price be less than the par value of the Common Stock at
such time. In making such adjustments, or in determining that no such
adjustments are necessary, the Board may rely upon the advice of counsel and
accountants to the Company, and the good faith determination of the Board shall
be final, conclusive and binding.

     SECTION 7. Rights as a Stockholder. A Participant shall have no rights as a
stockholder with respect to any shares covered by a Substitute Option until the
date of an entry evidencing such ownership is made in the stock transfer books
of the Company (the "Exercise Date"). Except as otherwise provided in Section 6,
no adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property) or distributions or other rights for which
the record date is prior to the Exercise Date. Upon (i) the dissolution,
liquidation or sale of all or substantially all of the business, properties and
assets of the Company, (ii) upon any reorganization, merger or consolidation in
which the Company does not survive, (iii) upon any reorganization, merger,
consolidation or exchange of securities in which the Company does survive and
any of the Company's stockholders have the opportunity to receive cash,
securities of another corporation and/or other property in exchange for their
capital stock of the Company, or (iv) upon any acquisition by any person or
group (as defined in Section 13(d) of the Securities Act of 1934) of beneficial
ownership of more than fifty percent (50%) of the Company's then outstanding
shares of Common Stock (each of the events described in clauses (i), (ii), (iii)
or (iv) is referred to herein individually as an "Extraordinary Event"), this
Plan and each outstanding Substitute Option shall terminate. In such event each
Participant shall have the right until 10 days before the effective date of the
Extraordinary Event to exercise, in whole or in part, any unexpired Substitute
Option held by such Participant to the extent that such Substitute Option is
then vested and exercisable pursuant to the provisions thereof.

     SECTION 8. Withholding of Taxes. The Company, or a Subsidiary, as the case
may be, may deduct and withhold from the wages, salary, bonus and other income
paid by the Company or such Subsidiary to any Participant the requisite tax upon
the amount of taxable income, if any, recognized by such Participant in
connection with the exercise in whole or in part of any Substitute Option, or
the sale of Common Stock issued to any Participant upon the exercise of any
Substitute Option, as may be required from time to time under any federal or
state tax laws and regulations. This withholding of tax shall be made from the
Company's (or such Subsidiary's) concurrent or next payment of wages, salary,
bonus or other income to such Participant or by payment to the Company (or such
Subsidiary) by such Participant of the required withholding tax, as the Board
may determine.

     SECTION 9. Amendment of this Plan. The Board may (a) make such changes in
the terms and conditions of outstanding Substitute Options as it deems
advisable, provided each Participant adversely affected by such change consents
thereto, and (b) make such amendments to this Plan as it deems advisable. The
Board may obtain shareholder approval of any amendment to this Plan for any
reason (including in order to take advantage of certain exemptions under Code
Section 162(m)), but shall not be required to do so

                                       2
<PAGE>

unless required by law or by the rules of the Nasdaq National Market or any
stock exchange on which the Common Stock may then be listed.

     SECTION 10. Governing Law. This Plan and any Substitute Option granted
pursuant to this Plan shall be construed under and governed by the laws of the
State of Delaware without regard to conflict of law provisions thereof.

     SECTION 11. Not an Employment or Other Agreement. Nothing contained in this
Plan or in any Substitute Option Agreement shall confer, intend to confer or
imply any rights of employment or any rights to any other relationship or rights
to continued employment by, or rights to a continued consulting relationship
with, the Company or any Subsidiary in favor of any Participant or limit the
ability of the Company or any Subsidiary to terminate, with or without cause, in
its sole and absolute discretion, the employment of, or relationship with, any
Participant, subject to the terms of any written employment or other agreement
to which such Participant is a party.

     SECTION 12. Indemnification. In addition to such other rights of
indemnification as they may have as directors, the members of the Board shall be
indemnified by the Company to the fullest extent permitted by law against the
reasonable expenses, including reasonable attorneys' fees, actually and
necessarily incurred in connection with the defense of any action, suit or
proceeding, or in connection with any appeal therein, to which they or any of
them may be a party by reason of any action taken or failure to act under or in
connection with this Plan or any Substitute Option granted hereunder, and
against all amounts paid by them in satisfaction of a judgment in any such
action, suit or proceeding, except in relation to matters as to which it shall
be adjudged in such action, suit or proceeding that such Board member is not
entitled to indemnification under applicable law.

adversely impact the exemption from registration under the Securities Act of
1933, as amended (the "Securities Act"), being relied upon for the sale of
Series A Preferred hereunder.

II.      REPRESENTATIONS AND WARRANTIES OF THE INVESTORS

         Each Investor, as to itself only, represents to the Company as follows:

         2.1. RISK. The Investor recognizes that its purchase of Series A
Preferred involves a high degree of risk in that: (i) the Company has incurred
losses since inception; at December 31, 1999, the Company had an accumulated
deficit of approximately $36,388,000; and the Company requires substantial funds
in addition to the proceeds of this private placement to continue its plan of
operations; (ii) an investment in the Company is highly speculative and only
investors who can afford the loss of their entire investment should consider
investing in the Company and the Series A Preferred; (iii) the Investor may not
be able to liquidate the Investor's investment; and (iv) transferability of the
Series A Preferred is extremely limited. Furthermore, the proceeds of this
private placement are projected to last only a limited period of time
(approximately four months). The Investor has read the Risk Factors section of
the Company's Annual Report on Form 10-K for the year ended December 31, 1999
(the "10-K").

         2.2. ACCREDITED INVESTOR. The Investor represents that the Investor is
an accredited investor as such term is defined in Rule 501 of Regulation D
promulgated under the Securities Act, as indicated by the Investor's responses
to the Confidential Purchaser Questionnaire (a form of which is attached to this
Agreement as Exhibit C) and that the Investor is able to bear the economic risk
of an investment in the Shares.

         2.3. INVESTMENT EXPERIENCE. The Investor acknowledges that the Investor
has prior investment experience, including investment in non-listed and
non-registered securities, or the Investor has employed the services of an
investment advisor to evaluate the merits and risks of an investment in the
shares of Series A Preferred on the Investor's behalf, and that the Investor
recognizes the highly speculative nature of the Investor's investment.

                                     - 2 -

<PAGE>

         2.4. DILIGENCE. The Investor acknowledges receipt and careful review of
the 10-K, the three reports on Form 10-Q filed by the Company with the
Securities and Exchange Commission (the "SEC") since the filing of the 10-K, and
the definitive proxy statement filed by the Company with the SEC in connection
with the Company's 2000 Annual Meeting of Stockholders. The Investor hereby
represents that the Investor has been furnished by the Company during the course
of this transaction with all information regarding the Company which the
Investor had requested or desired to know, that all documents which could be
reasonably provided have been made available for the Investor's inspection and
review, and that such information and documents have, in the Investor's opinion,
afforded the Investor with substantially all of the same information that would
be provided the Investor in a registration statement filed under the Securities
Act; and that the Investor has been afforded the opportunity to ask questions of
and receive answers from duly authorized officers or other representatives of
the Company concerning the terms and conditions of the Private Placement, and
any additional information which the Investor had requested. The Investor hereby
represents that, except as set forth in this Agreement, no representations or
warranties have been made to the Investor by the Company or any agent, employee
or affiliate of the Company and in entering into this transaction, the Investor
is not relying on any information, other than (i) information contained in the
10-K and other filings made by the Company with the SEC, (ii) the
representations made by the Company herein and (iii) the results of independent
investigation by the Investor.

         2.5. UNREGISTERED OFFERING. The Investor hereby acknowledges that the
sale of Series A Preferred has not been registered under the Securities Act
because of the Company's intention that this be a nonpublic offering pursuant to
Sections 4(2) or 3(b) of the Securities Act. The Investor represents that the
shares of Series A Preferred are being purchased for the Investor's own account,
for investment and not for distribution or resale to others. The Investor agrees
that the Investor will not sell or otherwise transfer the shares of Series A
Preferred unless they are registered under the Securities Act or unless an
exemption from such registration is available. The Investor understands that the
shares of Series A Preferred have not been registered under the Securities Act
by reason of a claimed exemption under the provisions of the Securities Act
which may depend, in part, upon the accuracy of the Investor's representations
in the Confidential Purchaser Questionnaire delivered by the Investor to the
Company.

         2.6. RULE 144. The Investor understands that Rule 144 ("Rule 144")
promulgated under the Securities Act requires, among other conditions, a
one-year holding period as a condition to the reseller not being deemed to be an
underwriter in any resale of "restricted" securities (as defined in Rule 144).
The Investor consents that the Company may, if it desires, permit the transfer
of the Shares out of the Investor's name only when the Investor's request for
transfer is accompanied by an opinion of counsel reasonably satisfactory to the
Company that the sale is made in compliance with Rule 144 or that an exemption
from registration is otherwise available. The Investor agrees to hold the
Company and its directors, officers and controlling persons and their respective
heirs, representatives, successors and assigns harmless and to indemnify them
against all liabilities, costs and expenses incurred by them as a result of any
misrepresentation made by the Investor contained herein or in the Confidential
Purchaser Questionnaire or any sale or distribution by the Investor in violation
of the Securities Act.

         2.7. LEGENDS. The Investor consents to the placement of a legend on any
certificate or other document evidencing the shares of Series A Preferred being
purchased by it stating that

                                      - 3 -

<PAGE>

they have not been registered under the Securities Act and setting forth or
referring to the restrictions on transferability and sale thereof.

         2.8. ADDRESS. The Investor hereby represents that the address of
Investor furnished by the Investor on the signature pages of this Agreement is
the undersigned's principal residence if the Investor is an individual or its
principal business address if it is a corporation or other entity.

         2.9. LIQUIDATION EVENT. The Investor agrees that neither the
Acquisition nor the Second Financing shall (i) constitute a Liquidation Event
for purposes of Section 4 of the Certificate of Designations for the Series A
Preferred or (ii) trigger any anti-dilution adjustment under Section 6 of the
Certificate of Designations for the Series A Preferred.

III.     REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as otherwise described in the 10-K and other documents filed by
the Company with the SEC subsequent to the filing of the 10-K, the Company
represents and warrants to each Investor as follows:

         3.1. ORGANIZATION. The Company is duly incorporated and validly
existing in good standing under the laws of the jurisdiction of its
organization. The Company has full power and authority to own, operate and
occupy its properties and to conduct its business as presently conducted and is
registered or qualified to do business and in good standing in each jurisdiction
in which it owns or leases property or transacts business and where the failure
to be so qualified would have a material adverse effect upon the business,
financial condition, properties or operations of the Company (a "Material
Adverse Effect"), and no proceeding has been instituted in any such jurisdiction
revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such
power and authority or qualification. Attached hereto as Exhibits D and E,
respectively, are true and complete copies of the Restated Certificate of
Incorporation and By-laws of the Company, each as amended to date, and no
proceedings have begun or are contemplated for the amendment of such documents.
The Certificate of Designations applicable to the Series A Preferred Stock
included in Exhibit D has been filed with, and accepted by, the Secretary of
State of the State of Delaware.

         3.2. DUE AUTHORIZATION. The Company has all requisite power and
authority to sell and issue the shares of Series A Preferred Stock being sold
hereunder, to reserve and issue the Common Stock ("Common Stock") issuable upon
conversion of such Series A Preferred Stock (the "Conversion Shares"), and to
execute, deliver and perform its obligations under this Agreement. This
Agreement has been duly authorized and validly executed and delivered by the
Company and constitutes the legal, valid and binding agreement of the Company
enforceable against the Company in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' and contracting
parties' rights generally and except as enforceability may be subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

         3.3. NON-CONTRAVENTION. The execution and delivery of this Agreement,
the issuance and sale of the shares of Series A Preferred Stock and the
Conversion Shares, the fulfillment of

                                     - 4 -

<PAGE>

the terms of this Agreement and the consummation of the transactions
contemplated hereby will not (A) conflict with or constitute a violation of,
or default (with the passage of time or otherwise) under, (i) any bond,
debenture, note or other evidence of indebtedness, or any lease, contract,
indenture, mortgage, deed of trust, loan agreement, joint venture or other
agreement or instrument to which the Company is a party or by which it or its
property is bound, where such conflict, violation or default is likely to
result in a Material Adverse Effect, (ii) the charter, by-laws or other
organizational documents of the Company, or (iii) any law, administrative
regulation, ordinance or order of any court or governmental agency,
arbitration panel or authority binding upon the Company or its property,
where such conflict, violation or default is likely to result in a Material
Adverse Effect, or (B) result in the creation or imposition of any lien,
encumbrance, claim, security interest or restriction whatsoever upon any of
the properties or assets of the Company or an acceleration of indebtedness
pursuant to any obligation, agreement or condition contained in any bond,
debenture, note or any other evidence of indebtedness or any indenture,
mortgage, deed of trust or any other agreement or instrument to which the
Company is a party or by which it is bound or to which any of the property or
assets of the Company is subject, where such lien, encumbrance, claim,
security interest or restriction is likely to result in a Material Adverse
Effect. No consent, approval, authorization or other order of, or
registration, qualification or filing with, any regulatory body,
administrative agency, or other governmental body in the United States is
required for the execution and delivery of this Agreement and the valid
issuance and sale of the Series A Preferred Stock or the Conversion Shares,
other than such as have been made or obtained.

         3.4.     CAPITALIZATION.

                  (a) The capitalization of the Company is described in the 10-K
and subsequent reports on Form 10-Q (the "SEC Documents") as of the dates set
forth therein. The Company has not issued any capital stock since September 30,
2000 other than 64,249 shares of Common Stock issued upon exercise of options

obligations). The Company has duly reserved 5,000,00 Conversion Shares. When
issued, the Conversion Shares will be duly and validly issued, fully paid and

fully paid and nonassessable, have been issued in compliance with all federal
and state securities laws, and were not issued in violation of any preemptive
rights or similar rights to subscribe for or purchase securities.

                  (b) Attached hereto as Schedule 3.4(b) is a schedule of all
outstanding options, warrants, and other instruments convertible directly or
indirectly into Common Stock, which schedule includes the exercise price of each
such instrument and any applicable vesting restrictions. Except as set forth on
such Schedule, there are no outstanding rights (including, without limitation,
preemptive rights), warrants or options to acquire, or instruments convertible
into or exchangeable for, any unissued shares of capital stock or other equity
interest in the Company, or any contract, commitment, agreement, understanding
or arrangement of any kind to

                                     - 5 -

<PAGE>

which the Company is a party and relating to the issuance or sale of any
capital stock of the Company, any such convertible or exchangeable securities
or any such rights, warrants or options.

                  (c) No preemptive right, co-sale right, registration right,
right of first refusal or other similar right exists with respect to the
issuance and sale of the shares of Series A Preferred Stock hereunder or the
issuance of the Conversion Shares upon conversion of the Series A Preferred.

                  (d) The Company does not own any securities of any other
entity. The Company is not subject to any obligation, contingent or otherwise,
to repurchase or otherwise acquire or retire any of its securities or any
options, warrants, or other rights to acquire any of its securities, nor will
the Company be obligated to provided registration rights to any person (except
to the Investors as contemplated herein).

                  (e) Except as set forth in Schedule 3.4(e), no stock plan,
stock purchase, stock option or other agreement or understanding between the
Company and any holder of any equity securities of the Company or rights to
purchase equity securities of the Company provides for acceleration or other
changes in the vesting provisions or other terms of such securities, as the
result of any merger, sale of stock or assets, change in control or other
similar transaction by the Company. The Company covenants that to the extent any
such acceleration may be effected at the option of the Company or its Board of
Directors, no such acceleration shall be effected in connection with this
Agreement, the Acquisition or the Second Financing. The Company is not a party
or otherwise subject to any agreement or understanding, and there is not, to the
Company's knowledge, any agreement or understanding between any persons or
entities, that affects or relates to the voting or giving of written consents
with respect to any security of the Company, or the voting by or for a director
of the Company, including without limitation voting trusts or agreements,
stockholders' agreements, pledge agreements, buy-sell agreements, rights of
first refusal or proxies relating to capital stock of the Company.

                  (f) Other than with respect to the Company's publicly-traded
warrants, the transactions contemplated hereby will not alter the terms of any
of the Company's securities, including without limitation, terms relating to
conversion or exercise prices and amounts.

         3.5. LEGAL PROCEEDINGS. There is no legal or governmental proceeding
pending to which the Company is a party or of which the business or property of
the Company is subject, except as disclosed in the SEC Documents.

         3.6. NO VIOLATIONS. The Company is not in violation of its charter,
bylaws or other organizational document, or in violation of any law,
administrative regulation, ordinance or order of any court or governmental
agency, arbitration panel or authority applicable to the Company, which
violation, individually or in the aggregate, would be reasonably likely to have
a Material Adverse Effect nor is the Company in default (and there exists no
condition which, with the passage of time or otherwise, would constitute a
default) in the performance of any bond, debenture, note or any other evidence
of indebtedness in any indenture, mortgage, deed of trust or any other agreement
or instrument to which the Company is a party or by which the Company

                                      - 6 -

<PAGE>

is bound or by which the property of the Company is bound, which would be
reasonably likely to have a Material Adverse Effect.

         3.7. GOVERNMENTAL PERMITS, ETC. The Company has all necessary
franchises, licenses, certificates and other authorizations from any foreign,
federal, state or local government or governmental agency, department or body
that are currently necessary for the operation of the business of the Company as
currently conducted except where the failure to currently possess could not
reasonably be expected to have a Material Adverse Effect.

         3.8. OFFERING. Subject in part to the accuracy of the representations
in Article II hereof, the offer, sale and issuance of the Series A Preferred
Stock hereunder in conformity with the terms of this Agreement (and the issuance
of the Conversion Shares) constitute transactions exempt from the registration
requirements of the Securities Act and from all applicable state securities or
"blue sky" laws, and neither the Company nor any authorized agent acting on its
behalf will take any action hereafter that would cause the loss of such
exemption. During the past six months, the Company has not offered any Common
Stock or any securities similar to the Common Stock or Series A Preferred for
sale to, or solicited any offers to buy any of the foregoing from, or otherwise
approached or negotiated in respect thereof with, any person or persons other
than a limited number of institutional or other sophisticated investors deemed
to be "accredited investors" (as such term is defined in Rule 501(a) promulgated
under the Securities Act) and other than certain employees, directors and
consultants who were granted stock options and, in any event, all such offerings
were exempt from registration under, and in accordance with, the Securities Act
and applicable state securities and "blue sky" laws.

         3.9. INTELLECTUAL PROPERTY.

                  (a) The Company has ownership or license or legal right to use
all patent, copyright, trade secret, trademark, customer lists, designs,
manufacturing or other processes, computer software, systems, data compilation,
research results or other proprietary rights used in the business of the Company
as currently conducted and as currently proposed to be conducted (collectively,
"Intellectual Property"). All of such patents, trademarks and registered
copyrights owned by the Company have been duly registered in, filed in or issued
by the United States Patent and Trademark Office, the United States Register of
Copyrights or the corresponding offices of other jurisdictions and have been
maintained and renewed in accordance with all applicable provisions of law and
administrative regulations in the United States and all such jurisdictions,
except where the failure to do so could not reasonably be expected to have a
Material Adverse Effect. Schedule 3.9 contains a complete list of all patents,
patent applications, trademarks, service marks and copyrights of the Company,
whether registered or unregistered, and applications therefor pending or under
preparation and registrations, renewals, extensions and the like thereof.

                  (b) All material licenses or other material agreements under
which (i) the Company is granted rights in Intellectual Property, other than
Intellectual Property generally available on commercial terms from other
sources, and (ii) the Company has granted rights to others in Intellectual
Property owned or licensed by the Company, are, to the knowledge of the Company,
after due investigation, in full force and effect and, to the knowledge of the
Company, there is no material default by any party thereunder.

                                    - 7 -

<PAGE>

                  (c) The Company believes it has taken all steps required in
accordance with sound business practice and business judgment to establish and
preserve its ownership of all material copyright, trade secret and other
proprietary rights with respect to its products and technology.

                  (d) To the knowledge of the Company, the present business,
activities and products of the Company do not infringe any intellectual property
of any other person, except where such infringement would not have a Material
Adverse Effect on the Company. No proceeding charging the Company with
infringement of any adversely held Intellectual Property has been filed. To the
knowledge of the Company, the Company is not making unauthorized use of any
confidential information or trade secrets of any person. To the knowledge of the
Company, no person is infringing upon the Intellectual Property. Neither the
Company nor, to the knowledge of the Company, any of its employees have any
agreements or arrangements with any persons other than the Company related to
confidential information or trade secrets of such persons, other than such
agreements that would not materially restrict the Company from conducting its
business as currently conducted.

                  (e) No proceedings (whether private or governmental) have been
instituted or are pending which challenge in a material manner the rights of the
Company to use the Intellectual Property. The Company has the right to use, free
and clear of material claims or rights of other persons, all of its Intellectual
Property. No order, holding or judgment has been rendered by any governmental or
judicial authority that limits the Company's use of the Intellectual Property.

         3.10. FINANCIAL STATEMENTS. The financial statements of the Company and
the related notes contained in the SEC Documents present fairly, in accordance
with generally accepted accounting principles, the financial position of the
Company as of the dates indicated, and the results of its operations and cash
flows for the periods therein specified. Such financial statements (including
the related notes) have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
therein specified. The Company does not have any material liabilities that are
not disclosed in the SEC Documents.

         3.11. NO MATERIAL ADVERSE CHANGE. Except as disclosed in the Company's
quarterly report on Form 10-Q for the quarter ended September 30, 2000, since
September 30, 2000, there has not been (i) any Material Adverse Effect affecting
the Company, (ii) any obligation, direct or contingent, that is material to the
Company, incurred by the Company, (iii) any dividend or distribution of any kind
declared, paid or made on the capital stock of the Company, or (iv) any loss or
damage (whether or not insured) to the physical property of the Company which
has been sustained which has a Material Adverse Effect.

         3.12. REPORTING STATUS. The Company has filed in a timely manner all
documents that the Company was required to file under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), during the 12 months preceding the
date of this Agreement. The following documents complied in all material
respects with the SEC's requirements as of their respective filing dates, and
the information contained therein as of the date thereof did not contain an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or

                                      - 8 -

necessary to make the statements therein in light of the circumstances under

SEC since December 31, 1999 pursuant to the reporting requirements of the
Exchange Act.

         3.13. FOREIGN CORRUPT PRACTICES. Neither the Company nor, to the
knowledge of the Company, any agent or other person acting on behalf of the
Company, have (i) directly or indirectly, used any corporate funds for unlawful
contributions, gifts, entertainment or other unlawful expenses related to
foreign or domestic political activity; (ii) made any unlawful payment to
foreign or domestic government officials or employees or to foreign or domestic
political parties or campaigns from corporate funds; (iii) failed to disclose
fully any contribution made by the Company or made by any person acting on its
behalf and of which the Company is aware in violation of law; or (iv) violated
in any material respect any provision of the Foreign Corrupt Practices Act of
1977, as amended.

         3.14. NO MANIPULATION OF STOCK. The Company has not taken and will not,
in violation of applicable law, take, any action designed to or that might
reasonably be expected to cause or result in unlawful manipulation of the price
of the Common Stock.

         3.15. CONTRACTS. Except as set forth in Schedule 3.15, the contracts
described in the SEC Documents or that are filed as exhibits thereto are in full
force and effect on the date hereof, and neither the Company nor, to the
Company's knowledge, any other party to such contracts is in breach of or
default under any of such contracts which would have a Material Adverse Effect.

the sale and transfer of the shares of Series A Preferred Stock to be sold

and all laws imposing such taxes will be or will have been fully complied with.

         3.17. INVESTMENT COMPANY. The Company is not an "investment company" or
an "affiliated person" of, or "promoter" or "principal underwriter" for an
investment company, within the meaning of the Investment Company Act of 1940, as
amended.

         3.18. OFFERING MATERIALS. The Company has not distributed and will not
distribute prior to the Closing Date to anyone other than the Investors any
offering material in connection with the offering and sale of the Series A
Preferred Stock. The Company has not in the past nor will it hereafter take any
action to sell, offer for sale or solicit offers to buy any securities of the

                                      - 9 -

Company which would bring the offer, issuance or sale of the shares of Series
A Preferred Stock, as contemplated by this Agreement, within the provisions
of Section 5 of the Securities Act.

         3.19. REGISTRATION RIGHTS. No persons have the right to require the
Company to include securities in a registration statement filed by the Company

placement of 1,505,003 shares of Common Stock and the Company's Warrant No. W-1

IV.      COVENANTS OF THE COMPANY

         4.1. BOARD; EXECUTIVE COMMITTEE.

                  (a) The Company's Board of Directors has, subject to the
consummation of this Agreement, duly expanded the size of the Board by 1 and
appointed Richard Franklin and Gere diZerega to fill the vacancies in the Board
of Directors. As long as Messrs. Franklin and diZerega (or other nominees of the
Investors holding a majority of the Series A Preferred ("Nominees")) shall be
directors of the Company, such persons shall be deemed to be the Series A
Directors (as defined in the Certificate of Designations for the Series A
Preferred); provided, however, that when the Series A Preferred converts into
Common Stock, Messrs. Franklin and diZerega (or such other Nominees) shall
continue to serve as directors of the Company until the next general election of
directors of the Company, subject to removal as provided under applicable law.

                  (b) The Company's Board of Directors has, subject to the
consummation of this Agreement, caused the Executive Committee of the Board of
Directors (the "Executive Committee") to consist of Robert Hickey, Richard
Franklin and Gere diZerega and no other members. The Executive Committee will
consist of these three individuals and no other members; except that if Mr.
Franklin or Mr. diZerega is no longer serving as a director and the holders of
Series A Preferred shall have designated a replacement Nominee, such Nominee
shall be appointed to the Executive Committee, and if Mr. Hickey is no longer
serving as a director, then a majority of the remaining directors may appoint
one of themselves to the Executive Committee, in each case in accordance with
Section 4.8 of the By-laws of the Company. Attached hereto as Schedule 4.1(b)
are the resolutions of the Board of Directors of the Company forming, and
defining the powers of, the Executive Committee. Such resolutions are in full
force and effect and there are no other resolutions pertaining to the subject
matter thereof. The Company will not hereafter take any action to disband or
otherwise limit the powers of the Executive Committee, and in this connection,
the Company will not amend in any respect the provisions of the Company's
By-laws governing the Executive Committee, other than in accordance with Section
10.1 of the By-laws. The Company's obligations under this Section 4.1(b) will
lapse upon conversion of the Series A Preferred into Common Stock.

                  (c) Without the consent of a majority of the full Executive
Committee or the Board of Directors (including at least one Series A Director),
the Company will not disburse any funds or incur any obligations of any nature
whatsoever. The Board of Directors will not overrule any action of the Executive
Committee except with the consent of at least one Series A Director. By
resolutions attached hereto as Exhibit 4.1(c), the Company has amended the
By-laws of the Company in accordance with Section 10.2 thereof to include the
first two sentences

                                     - 10 -

<PAGE>

of this Section 4.1(c), and the Company will not amend, alter or repeal such
amendments to the Company's By-laws, other than in accordance with Section
10.1 of the By-laws. The Company's obligations under this Section 4.1(c) will
lapse upon conversion of the Series A Preferred into Common Stock.

         4.2. LISTING. The Company agrees to take all action required to list
the Conversion Shares on any stock exchange or quotation system on which the
Company's Common Stock may be listed or quoted.

         4.3. RULE 144. With a view to making available the benefits of certain
rules and regulations of the SEC which may at any time permit the sale of the
Conversion Shares to the public without registration, the Company agrees to:

                  (a) Make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) File with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act;
and

                  (c) So long as an Investor owns any Series A Preferred or
Conversion Shares, furnish to the Investor forthwith upon request a written
statement by the Company as to its compliance with the reporting requirements of
Rule 144 and of the Securities Act and the Exchange Act, a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents of the Company as such Investor may reasonably request in availing
itself of any rule or regulation of the SEC allowing an Investor to sell any
such securities without registration.

         4.4. USE OF PROCEEDS. The $500,000 invested by the Investors hereunder
will be used as directed by the Executive Committee.

         4.5. SUBORDINATION OF REGISTRATION RIGHTS. Set forth on Schedule 5.5 is
a list of the purchasers in the Company's private placement of Common Stock
completed in June, 1999. The Company has obtained the agreement of the indicated
purchasers that the registration rights applicable to the securities purchased
in such private placement will be subordinated to the rights of the holders of
"Warrants" and "Warrant Securities," as such terms are defined as of the date
hereof in the Company's Warrant No. W-1 dated May 8, 1996 issued to Wedbush
Morgan Securities, Inc. The Company will use commercially reasonable efforts to
obtain similar agreements from the remaining purchasers.

V.       COVENANTS OF THE INVESTORS

         5.1. CONFIDENTIALITY. Each Investor agrees, as to itself and not the
other Investors, that it will not disclose the terms of this Agreement, or any

this Agreement and which the Company has identified as material nonpublic
information, except to the extent (i) that such terms or other information
become generally available to the public other than by disclosure in violation
of this Agreement, (ii) that such information was properly within the Investor's
possession prior to being furnished by the Company, (iii) that such information
becomes available to the Investor on

                                      - 11 -

a non-confidential basis, such as through disclosure by third parties who
