ITEM 1.           SECURITY AND ISSUER.

         This statement on Schedule 13D is being filed by the Reporting Persons
with respect to the common stock, par value $.01 per share (the "Common Stock"),
of SPAR Group, Inc., a Delaware corporation formerly known as PIA Merchandising
Services, Inc. (the "Company"). This statement is being filed in connection with
the consummation of the merger (the "Merger") of SG Acquisition, Inc., a Nevada
corporation and a wholly-owned subsidiary of the Company prior to the Merger
("PIA Acquisition") into SPAR Acquisition, Inc., a Nevada corporation and
wholly-owned subsidiary of the Company ("SAI"). Pursuant to the Merger, the
Company has been renamed "SPAR Group, Inc." The address of the Company's
principal executive offices is 19900 MacArthur Boulevard, Suite 900, Irvine,

of Grantor Trust II of Robert G. Brown dated March 22, 1999 ("Grantor Trust II")
for the benefit of James R. Brown, Sr.'s children due to the fact that Grantor

outstanding Common Stock, and as a result is not a "Reporting Person" required
to file a Schedule. However, all of the 180,000 shares owned by Grantor Trust II
are being reported on this statement under the beneficial ownership of James R.
Brown, Sr. and Robert G. Brown who, together with Mr. William H. Bartels, are
co-trustees of Grantor Trust II. Robert G. Brown and James R. Brown, Sr. are
sometimes referred to individually as a "Reporting Person" and collectively as
the "Reporting Persons".

such Reporting Person, no Reporting Person has responsibility for the accuracy
or completeness of the information supplied by any other Reporting Person, and
each Reporting Person agrees that this statement is filed on behalf of such
Reporting Person only.

         The Reporting Persons may be deemed to constitute a "group" for the
purposes of Section 13(d)(3) of the Exchange Act, although neither the fact of
this filing nor anything contained herein shall be deemed to be an admission by
any of the Reporting Persons that such a "group" exists.

         (b) Mr. Robert G. Brown's business address is c/o the Company, 303
South Broadway, Suite 140, Tarrytown, New York 10591. The business address of

ITEM 3.           SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         On July 8, 1999, the Merger contemplated by the Agreement and Plan of
Merger dated as of February 28, 1999, as amended as of May 14, 1999 (as amended,
the "Merger Agreement") among the Company, PIA Acquisition, PIA Merchandising,
Co., Inc., a California corporation and a wholly-owned subsidiary of the Company
("PIA Merchandising"), SAI, SPAR MCI Performance Group, Inc., a Delaware
corporation, SPAR Incentive Marketing, Inc., a Delaware corporation, SPAR
Marketing Force, Inc., a Nevada corporation, SPAR Marketing, Inc., a Delaware
corporation, SPAR, Inc., a Nevada corporation, SPAR/Burgoyne Retail Services,
Inc., an Ohio corporation, SPAR Marketing, Inc., a Nevada corporation, and SPAR
Trademarks, Inc., a Nevada corporation (all of the SPAR companies collectively,
the "SPAR Companies"), was consummated. As a result of the Merger, PIA
Acquisition, a wholly owned subsidiary of the Company, merged with and into SAI,
the ultimate parent company of the SPAR Companies, with SAI as the surviving
corporation.

         Pursuant to the Merger Agreement, on July 8, 1999, in exchange for
outstanding shares of SAI common stock, 5,576,965 shares of Common Stock were
issued to Robert G. Brown individually, 1,800,000 shares of Common Stock were
issued to Grantor Trust I, and 180,000 shares of Common Stock were issued to
Grantor Trust II. In addition, 25,000 shares of Common Stock were issued to
James R. Brown, Sr., individually. Each of Robert G. Brown, James R. Brown, Sr.
and William H. Bartels is a co-trustee of Grantor Trust I and Grantor Trust II,
respectively.

         The description of the Merger Agreement in this statement does not
purport to be complete and is qualified in its entirety by the express terms and
provision of the Merger Agreement. A copy of the Merger Agreement and the
amendment thereto are attached as Exhibit 2 and Exhibit 3 hereto, respectively,
and are incorporated herein by reference.

ITEM 4.           PURPOSE OF TRANSACTION.

         Pursuant to the Merger Agreement, on July 8, 1999, following the
approval of the Company's stockholders at the annual meeting of stockholders
held on that date (the "Annual Meeting"), PIA Acquisition merged with and into
SAI, with SAI continuing as the surviving corporation and a wholly-owned
subsidiary of the Company. The purpose of the Merger was to combine the
businesses of the Company and the SPAR Companies and for Robert G. Brown and
William H. Bartels (together, the "SAI Principals") to acquire control of the
Company. Immediately prior to the consummation of the Merger, SAI owned,
directly or indirectly, all of the issued and outstanding capital stock of the
SPAR Companies. On July 8, 1999, as part of the transactions contemplated by the
Merger Agreement, the Company (a) amended its certificate of incorporation to
(i) change its name to "SPAR Group, Inc.", (ii) increase the number of
authorized shares of its Common Stock, from 15,000,000 to 47,000,000, and (iii)
delete the prohibition on stockholder action by written consent without a
meeting under Delaware law, and (b) amended its Amended and Restated 1995 Stock
Option Plan (the "1995 Stock Option Plan"), to increase the number of shares of
Common Stock reserved for issuance upon exercise of stock options granted
thereunder from 1.3 million to 3.5 million.

         As a result of the Merger (a) the holder of each share of the common
stock of SAI issued and outstanding at the effective time of the Merger received
one share of Common Stock, or an aggregate of 12,659,487 shares of Common Stock
and (b) the Company assumed all of the stock options of SAI outstanding at the
effective time of the Merger and issued substitute options to acquire 134,114
shares of Common Stock, at an exercise price of $.01 per share, to the holders
thereof. The Company also issued stock options to acquire an aggregate of
2,133,744 shares of Common Stock to certain of its employees, consultants and
other persons performing valuable services to the Company under the 1995 Stock
Option Plan.

         In exchange for their shares of SAI common stock, the existing
stockholders of SAI, including the SAI Principals prior to the Merger, Robert G.
Brown and William H. Bartels, were issued shares of Common Stock and substitute
options representing approximately 70% of the outstanding shares of Common Stock
immediately following the Merger. As a result of the Merger, Robert G. Brown may
be deemed to be the beneficial owner, directly or indirectly, of approximately
41.7% of the outstanding shares of Common Stock and Mr. William H. Bartels, the
Vice Chairman and a director of the Company, may be deemed to be the beneficial
owner of approximately 26.5% of the outstanding shares of Common Stock.

                                                           ----    -----



         In connection with the Merger, Robert G. Brown was appointed the
Chairman, Chief Executive Officer and President of the Company. In addition, at
the closing of the Merger, except for Mr. Patrick W. Collins and Mr. J.
Christopher Lewis, all of the Company's seven directors elected at the Annual
Meeting resigned from the Board of Directors of the Company. Messrs. Collins and
Lewis appointed Messrs. Brown and Bartels and Mr. Robert O. Aders to fill three
of the remaining five vacancies on the Board. There are currently two vacancies
on the Board. As an officer and director of the Company, Robert G. Brown
regularly explores potential actions and transactions which may be advantageous
to the Company, including without limitation possible mergers, acquisitions, or
other material changes in the business, corporate structure, capitalization,
management, policies, securities or regulatory or reporting obligations of the
Company.

         As a result of Nasdaq's determination that the Merger constituted a
"reverse merger" under Nasdaq Marketplace Rule 4330(f), Nasdaq has informed the
Company that, as a result of the Merger, the Company must satisfy Nasdaq's
initial listing requirements for continued quotation of the Common Stock on the
Nasdaq National Market. A hearing is scheduled with Nasdaq on August 12, 1999 at
which the Company will appeal Nasdaq's determination. While the Company is
appealing this determination from Nasdaq, there can be no assurance that such
appeal will be successful and, if the Company cannot meet such initial listing
requirements and all other Nasdaq requirements, the Common Stock could be
delisted from the National Market. If this occurs, the Company presently intends
to list the Common Stock on the Nasdaq Small Cap Market, American Stock Exchange
or other national securities exchange.

         Except as otherwise set forth herein, and except for the activities of
Robert G. Brown on behalf of the Company, the Reporting Persons have no plans or
proposals which relate to or would result in (i) the acquisition of additional
securities of the Company; (ii) an extraordinary corporate transaction, such as
a merger, reorganization or liquidation of the Company; (iii) a sale or transfer
of a material amount of assets of the Company or any of its subsidiaries; (iv)
any change in the present Board of Directors or management of the Company,
including any plans or proposals to change the number or term of directors or to
fill any existing vacancies on the Board; (v) any material change in the present
capitalization or dividend policy of the Company; (vi) any other material change
in the Company's business or corporate structure; (vii) any changes in the
Company's charter, by-laws or instruments corresponding thereto or other actions
which may impede the acquisition of control of the Company by any person; (viii)
causing a class of securities of the Company to be delisted from a national
securities exchange or cease to be authorized to be quoted in an inter-dealer
quotation system of a registered national securities association; (ix) causing a
class of equity securities of the Company to become eligible for termination of
registration pursuant to Section 12(g)(4) of the Exchange Act; or (x) any action
similar to any of those enumerated above.

("SIM"), SPAR MCI Performance Group, Inc., a Delaware corporation ("SMCI"),  and

are sometimes referred to herein  individually as a "SPAR Marketing Company" and
collectively  as the  "SPAR  Marketing  Companies".  SMI and the SPAR  Marketing
Companies are sometimes  referred to herein  individually  as a "SPAR  Marketing
Party"  and  collectively  as the  "SPAR  Marketing  Parties".  SIM and SMCI are
sometimes  referred  to herein  individually  as a "SPAR  Incentive  Party"  and
collectively  as the "SPAR  Incentive  Parties".  SAI,  STM, the SPAR  Marketing
Parties  and the SPAR  Incentive  Companies  are  sometimes  referred  to herein
individually  as a "SPAR  Party" and  collectively  as the "SPAR  Parties".  PIA

individually  as a "PIA Party" and  collectively  as the "PIA Parties".  The PIA

                                    Recitals

         A. Robert G. Brown and William H. Bartels (each a "SPAR Principal", and
collectively  the "SPAR  Principals")  own a majority of all of the  outstanding
shares of common stock of SAI, par value $0.01 per share ("SAI Stock"),  and all
of the  outstanding  capital  stock of the  other  SPAR  Parties  as of the date
hereof.  The SPAR  Principals  together  with  other  owners  of SAI  Stock  are
sometimes   referred  to  herein   individually  as  a  "SPAR  Stockholder"  and
collectively  as the "SPAR  Stockholders".  Options to acquire  shares of common
stock of SAI (each a "SAI Option" and  collectively  the "SAI  Options") will be
held by certain employees of the SPAR Parties, certain others providing services
to the SPAR Parties and certain other  persons  (each a "SAI Option  Holder" and
collectively  the "SAI Option Holders") in the aggregate amount and on the terms
described in the SPAR Disclosure Letter.

         B.  The  SPAR  Principals  also own all of the  outstanding  shares  of
capital stock, and are officers and directors,  of: (i) SPAR Marketing Services,
Inc., a Nevada  Corporation  ("SMS"),  which  provides  certain  field  services
pursuant  to Service  Agreement  dated as of January 4, 1999 (as the same may be
supplemented,  modified,  amended, restated or replaced from time to time in the
manner provided  therein,  the "Field Service  Agreement");  (ii) SPAR InfoTech,
Inc. ("SIT"),  a startup venture that provides certain  programming  services to
the SPAR  Marketing  Parties;  and (iii) SPAR Group,  Inc.  ("SGI"),  a Delaware
corporation  that will change its name prior to the  Effective  Time.  SMS, SIT,
STM, SGI and any other companies  owned by the SPAR  Principals  (other than the
SPAR Parties) and their  respective  assets and  properties  are not part of the
proposed merger transactions.

         C. On January 15, 1999, SMCI purchased  substantially all of the assets
and assumed  certain  liabilities  (the "MCI  Acquisition")  of MCI  Performance
Group,  Inc.,  a  Texas  corporation  ("MCI"),  pursuant  to an  Asset  Purchase
Agreement  dated as of  December  22,  1998,  among MCI,  John H. Wile (the "MCI
Stockholder")  and SMCI, as amended by a First Amendment dated as of January 15,
1999  (as  amended,  and as the  same may be  supplemented,  modified,  amended,
restated or replaced from time to time in the manner provided therein,  the "MCI
Purchase  Agreement"),  under which SGI is a guarantor.  The MCI Acquisition was
financed in part by SMCI's  issuance of its  Promissory  Note to MCI dated as of
January 15, 1999 (as the same may be supplemented,  modified,  amended, restated
or replaced from time to time in the manner provided  therein,  the "MCI Note"),
which  MCI Note is  secured  by the  pledge  to MCI of all of the  stock of SMCI
pursuant to the  Hypothecation  Agreement from the SPAR  Principals  dated as of
January 15, 1999 (as the same may be supplemented,  modified,  amended, restated
or  replaced  from  time  to time  in the  manner  provided  therein,  the  "MCI
Hypothecation").  The MCI Purchase Agreement  contains certain  representations,
warranties and  indemnifications  of MCI and the MCI Stockholder with respect to
the assets, business and liabilities of MCI acquired by SMCI thereunder.

         D. The SPAR  Principals  have entered  into an agreement  with the SPAR
Parties  dated  as of  February  28,  1999  (as the  same  may be  supplemented,
modified, amended, restated or replaced from time to time in the manner provided
therein,  the "SPAR Reorganization  Agreement"),  pursuant to which (i) the SPAR
Principals have agreed to contribute to SAI all of their shares of STM, the SPAR
Marketing  Parties and SPAR Incentive Parties in return for the issuance to them
of additional shares of SAI Stock as provided  therein,  and (ii) SAI would then
contribute  the capital  stock of SMCI to SIM and the capital  stock of the SPAR
Marketing  Companies to SMI, such that SAI will be the sole  stockholder of STM,
SIM and SMI, SIM will be the sole  stockholder of SMCI, and SMI will be the sole
stockholder of the SPAR Marketing  Companies.  The  transactions  to be effected
pursuant  to the  Reorganization  Agreement  will be  referred  to as the  "SPAR
Reorganization  Transactions"  and collectively with the MCI Acquisition will be
referred to as the "SPAR Premerger  Transactions".  The MCI Purchase  Agreement,
the MCI Note and related documents and the SPAR Reorganization  Agreement may be
referred to individually as a "SPAR Premerger Agreement" and collectively as the
"SPAR Premerger Agreements".

         E. Pursuant to the SPAR Reorganization Agreement, SAI will issue to the
SPAR Principals  sufficient additional shares of SAI Stock such that (after such
issuance and including shares previously issued to them) they will then together
own shares of SAI Stock equal in number to (i) the  product of (A) 2.2546  times
(B) the total number of shares of PIA Delaware  Stock (as  hereinafter  defined)
issued and outstanding as of the close of business on the Business Day preceding
the Closing Date (as defined in the  Reorganization  Agreement),  minus (ii) the
sum of the  number  of shares of SAI Stock  issuable  upon  exercise  of the SAI
Options (without regard to the vesting provisions thereof).

         F. The SPAR  Principals and the  respective  Boards of Directors of the
SPAR Parties have approved the SPAR Premerger Transactions.

         G. PIA  Acquisition  and PIA  California  each is a direct wholly owned
subsidiary of PIA Delaware.

         H. The  respective  Boards of  Directors  of the PIA Parties and of the
SPAR Parties deem it advisable  and in the best  interests of such  corporations
and their respective  stockholders that,  following the consummation of the SPAR
Reorganization  Transactions,  PIA  Acquisition  merge  with  and  into SAI (the
"Merger")  pursuant  to this  Agreement  and the  applicable  provisions  of the
General  Corporation  Law of the  State  of  Nevada  (the  "NGCL").  SAI and PIA
Acquisition  are  sometimes   collectively   referred  to  as  the  "Constituent
Corporations"  and SAI,  following the Merger,  is sometimes  referred to as the
"Surviving Corporation".

         I. As provided herein, (i) as a result of the Merger,  each outstanding
share of SAI Common Stock will be converted  into the right to receive one share
of common  stock of PIA  Delaware,  par value  $0.01  per share  ("PIA  Delaware
Stock"),  and (ii)  following the Merger,  each SAI Option Holder will receive a
Substitute Option (as hereinafter defined) to purchase the same number of shares
of PIA  Delaware  Stock on the same  terms as the  number of shares of SAI Stock
that such SAI Option  Holder was  entitled  to  purchase  under such SAI Option.
Immediately  following the Merger,  (A) the SPAR  Stockholders will hold and the
SAI Option Holders will have the right to acquire upon exercise  (without regard
to vesting) shares of PIA Delaware Stock that, in the aggregate,  will represent
approximately  69.274%  of the sum of (1) the  total  number  of  shares  of PIA
Delaware Stock issued and outstanding  immediately after the Merger plus (2) the
total  number of shares of PIA  Delaware  Stock  issuable  upon  exercise of the
Substitute  Options  (without  regard  to  vesting),  and (B) the  shares of PIA
Delaware Stock held by  stockholders  of PIA Delaware  immediately  prior to the
Merger will represent approximately 30.726% of such post-Merger sum.

         J. The respective Boards of Directors of PIA Delaware,  PIA Acquisition
and SAI have approved the Merger on the terms and subject to the  conditions set
forth herein.

         K.  The   Parties   intend   the   Merger  to  qualify  as  a  tax-free
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code").


                                    AGREEMENT

                  In  consideration  of the foregoing,  the mutual covenants and
agreements hereinafter set forth, and other good and valuable consideration (the
receipt  and  adequacy  of which is hereby  acknowledged  by the  Parties),  the
Parties hereto hereby agree as follows:

                  Section  1.01.  The  Merger.  Upon the  terms  and  conditions
hereinafter set forth and in accordance with the NGCL, at the Effective Time (as
defined in Section 1.02), PIA Acquisition shall be merged with and into SAI, and
thereupon the separate existence of PIA Acquisition shall cease, and SAI, as the
Surviving  Corporation,  shall  continue  to exist  under and be governed by the
NGCL.

                  Section  1.02.  Closing;  Effective  Time of the  Merger.  The
consummation of the transactions  contemplated by this Agreement (the "Closing")
shall take place at the offices of Parker Chapin  Flattau & Klimpl,  LLP, in New
York, New York, at 10:00 a.m. on a date to be designated by mutual  agreement of
PIA  Delaware  and SAI (the  "Closing  Date"),  which shall be no later than the
second business day after the satisfaction  (or, to the extent permitted by law,
the waiver) of the conditions set forth in Article VI.  Concurrently  with or as
soon as practicable  after the Closing,  PIA Delaware,  PIA  Acquisition and SAI
will cause  Articles of Merger in  substantially  the form of Exhibit A attached
hereto (the "Articles of Merger") to be executed and filed with the Secretary of
State of the State of Nevada as  provided  in Section  92A.200 of the NGCL.  The
Merger shall become  effective  immediately  upon such filing of the Articles of
Merger with the  Secretary of State of the State of Nevada or at such other time
as PIA  Acquisition  and SAI shall agree and specify in the  Articles of Merger.
The time of the  effectiveness  of the Merger is  sometimes  referred  to as the
"Effective Time."

                  Section 1.03.    Name,  Certificate of Incorporation,  Bylaws,
Board  of  Directors  and  Officers  of  the  Surviving  Corporation.  Upon  the
effectiveness of the Merger:

(a)      the name of the Surviving Corporation shall be "SPAR Acquisition, Inc."

(b)      the Certificate of Incorporation of the Surviving  Corporation shall be
         the Certificate of  Incorporation  of SAI until thereafter duly amended
         or restated;

(c)      the  Bylaws of the  Surviving  Corporation  shall be the  Bylaws of SAI
         until thereafter duly amended or restated;

(d)      the  directors  of SAI shall serve as the  directors  of the  Surviving
         Corporation  until their  respective  successors have been duly elected
         and qualified; and

(e)      the  officers  of SAI  shall  serve as the  officers  of the  Surviving
         Corporation in the same capacity or capacities  until their  respective
         successors have been duly appointed.

                  Section 1.04. Effects of the Merger. The Merger shall have the
effects set forth in Section  92A.250 of the NGCL.  Without in any way  limiting
such effects,  at and after the Effective Time (a) the Constituent  Corporations
shall merge and become and continue as part of a single corporation,  SAI, which
is the Surviving  Corporation,  and (b) the Surviving  Corporation shall (to the
same  extent  and with  the same  effect  as was the  case  with the  applicable
Constituent Corporation):  (i) own and possess any and all (A) financial assets,
accounts, documents,  instruments,  equipment, inventory, intellectual property,
contracts, general intangibles, real property and improvements, and other assets
and  properties  of  each  Constituent  Corporation,  and  (B)  rights,  powers,
privileges,  security  or other  entitlements,  licenses,  franchises  and other
interests of each  Constituent  Corporation,  all of which will be automatically
vested in the  Surviving  Corporation  at the  Effective  Time  (subject  to any
existing liens or encumbrances thereon,  which shall continue  unimpaired),  and
none of which shall be impaired or otherwise  adversely  affected by the Merger;
and (ii) be liable for all of the debts, liabilities,  obligations and duties of
each Constituent  Corporation,  all of which will continue unimpaired and may be
enforced  against the Surviving  Corporation to the same extent as it would have
been enforceable against the applicable Constituent Corporation.

                  Section  1.05.  Tax  Consequences.  The Merger is  intended to
constitute  a  reorganization  within the meaning of Section 368 of the Code for
federal  income  tax  purposes,  and the  Parties  will  take  all  commercially
reasonable  steps in furtherance  thereof,  including  (without  limitation) the
making of all  required  filings and the keeping of all  required  records.  The
parties  to  this   Agreement   hereby  adopt  this  Agreement  as  a  "plan  of
reorganization"  within the meaning of  ss.ss.1.368-2(g)  and  1.368-3(a) of the
United States Treasury Regulations.

                  Section 1.06.  Further  Assurances.  If, at any time after the
Effective Time, the Surviving  Corporation shall consider or be advised that any
further deeds, assignments or assurances in law or any other acts are necessary,
desirable or proper to vest, perfect or confirm, of record or otherwise,  in the
Surviving  Corporation,  the title to any  property or right of the  Constituent
Corporations  acquired  or to be  acquired  by reason of, or as a result of, the
Merger, or otherwise to carry out the purposes of this Agreement,  the Surviving
Corporation  and its proper officers and directors (on behalf of PIA Acquisition
or SAI) shall execute and deliver all such deeds,  assignments and assurances in
law and do all acts necessary,  desirable or proper to vest,  perfect or confirm
title to such  property or right in the Surviving  Corporation  and otherwise to
carry out the purposes of this Agreement,  and the proper officers and directors
of the  Surviving  Corporation  are  fully  authorized  to take any and all such
action.

                                   ARTICLE II

                              MERGER CONSIDERATION

                  Section 2.01.   Conversion  of  Capital  Stock,  Etc.  At the
Effective Time and without any further action on the part of the holder thereof:

(a)      each  share of SAI Stock  that is issued  and  outstanding  immediately
         prior to the Effective Time shall  automatically  be converted into the
         right to  receive  one (1) fully  paid and  nonassessable  share of PIA
         Delaware  Stock  (which 1:1 ratio will be referred to as the  "Exchange
         Ratio"); and

(b)      each  share of common  stock of PIA  Acquisition,  par  value  $.01 per
         share,  that  is  issued  and  outstanding  immediately  prior  to  the
         Effective Time shall, by virtue of the Merger and without any action on
         the part of PIA Delaware as the holder  thereof,  be converted into and
         become one (1) share of common stock of the Surviving Corporation,  par
         value $.01 per share.

                  Section  2.02.  Exchange  Procedures.  Following the Effective
Time,  upon  surrender  to  PIA  Delaware  of  stock  certificates  representing
outstanding shares of SAI Stock (the  "Certificates"),  each holder of SAI Stock
shall be  entitled  to  receive,  in  exchange  therefor,  one or more new stock
certificates representing,  in the aggregate, that number of whole shares of PIA
Delaware  Stock which such  holder has the right to receive  pursuant to Section
2.01(a)  in  respect of the  shares of SAI Stock  evidenced  by the  Certificate
surrendered,  and each  Certificate so surrendered  shall forthwith be canceled;
provided, however, that PIA Delaware shall cause ten percent (10%) of the shares
which each SPAR Principal and their Family Members (as herinafter defined) would
otherwise have had the right to receive  pursuant to Section 2.01(a) (the "Share
Escrow Amount") to be registered in the name of, and delivered to, the Indemnity
Escrow Agent (as such term is defined in Section  6.01(g)  hereof) to be held in
accordance with the provisions of the Limited Indemnification  Agreement and the
Indemnity  Escrow  Agreement  (as such  terms are  defined  in  Section  6.01(g)
hereof);  and provided  further that the Share Escrow Amount may be satisfied by
the  shares of the SPAR  Principals  as  opposed  to the  shares of such  Family
Members.

                  Section 2.03. No Fractional Shares.  Notwithstanding any other
provision of this Article II, no fractional  shares of PIA Delaware  Stock shall
be issued in  connection  with the Merger  and any holder of SAI Stock  entitled
hereunder  to  receive a  fractional  share of PIA  Delaware  Stock but for this
Section  shall be entitled to receive from PIA Delaware a cash payment  (rounded
to the nearest whole cent) equal to the product of such  fraction  multiplied by
the last sale price of PIA  Delaware  Stock as reported  on the Nasdaq  National
Market on the Closing Date.

                  Section 2.04. SAI Option  Assumption  and Exchange.  As of the
Effective  Time,  PIA  Delaware  shall  be  deemed  to have  assumed  all of the
outstanding  SAI Options,  in each case on the terms and conditions set forth in
the  written  option  agreements  (copies  of which  have been  provided  to PIA
Delaware). PIA Delaware shall issue to each holder of an outstanding SAI Option,
against delivery and  cancellation of the agreement  evidencing such outstanding
SAI Option, a new substitute option (a "Substitute Option") under PIA Delaware's
Special Purpose Stock Option Plan substantially in the form of Exhibit B hereto,
together  with such changes  therein as may be made with the approval of the PIA
Delaware Board and SAI (the "PIA Special Purpose Plan").  Each Substitute Option
shall entitle the SAI Option Holder to purchase the same number of shares of PIA
Delaware  Stock as the  number  of  shares of SAI  Stock  that  could  have been
purchased  under the SAI Option  (reflecting  the 1:1 Exchange  Ratio) and shall
otherwise  be  issued  upon the same  terms and  conditions  as set forth in the
written agreement  evidencing the SAI Option so surrendered,  including (without
limitation)  the same per share  exercise price and the same vesting (if any) as
the  surrendered SAI Option.  Each SAI Option so surrendered  shall forthwith be
canceled.

                  Section  2.05.  Granting  of New Stock  Options  under the PIA
Stock Option Plan. Subject to the consummation of the Merger and the approval by
the  stockholders of PIA Delaware of the Proposed Plan Amendment (as hereinafter
defined),  effective as of the close of business on the date on which the Merger
is consummated,  PIA Delaware shall issue, subject to the availability of shares
under PIA Delaware's Amended and Restated 1995 Stock Option Plan (the "PIA Stock
Option  Plan"),  stock  options under the PIA Stock Option Plan (each a "New PIA
Option")  to the  persons  and in the  amounts  (which may  include  unallocated
amounts for later  allocation by SAI) listed in the letter of even date herewith
delivered to PIA Delaware (the "New Option Schedule"), which stock options shall
cover an  aggregate  of  2,133,744  shares  of PIA  Delaware  Stock.  Except  as
otherwise indicated on the New Option Schedule or in the terms of the agreements
governing such options,  each New PIA Option shall (i) vest (become exercisable)
in four equal annual installments, (ii) have an exercise price equal to the last
sale price for the PIA Delaware Stock as reported on the Nasdaq  National Market
on the  date of  issuance  and  (iii)  have  such  other  terms  and  conditions
consistent  with the PIA  Stock  Option  Plan as the Board of  Directors  of PIA
Delaware  may  determine.  The New  Option  Schedule  may be  amended by SAI (by
written  notice  to PIA  Delaware)  at any  time  prior to the  issuance  of the
affected  New PIA Options to add or delete  names or to increase or decrease the
number  of  shares  to be  covered  by any  unissued  proposed  New PIA  Option;
provided,  however,  that the aggregate  number of shares of PIA Delaware  Stock
issuable  upon  exercise of all New PIA Options  (without  regard to the vesting
provisions  thereof) shall not exceed 2,133,744 shares without the prior written
consent of PIA Delaware;  and provided  further that the terms and conditions of
any New PIA Option  indicated  on the New Option  Schedule as of the date hereof
may  not  be  materially  improved  (other  than a  reallocation  of  shares  or
allocation of previously  unallocated  shares to any employee or other recipient
permitted  under the PIA Stock Option Plan) without the prior written consent of
PIA Delaware.

                  Section 2.06.  Reservation and  Registration of Option Shares.
PIA Delaware shall take all corporate action necessary to reserve for issuance a
sufficient  number of shares of PIA Delaware Stock for delivery upon exercise of
the Substitute Options and the New PIA Options. As soon as practicable after the
Effective  Time,  to the extent such form is  available  therefor,  PIA Delaware
shall file a  registration  statement on Form S-8 (or any  successor  form) with
respect to the shares of PIA Delaware  Stock subject to the  Substitute  Options
and the New PIA Options  (and any other PIA Options  that the PIA Board may wish
to treat similarly).  PIA Delaware shall use commercially  reasonable efforts to
maintain the  effectiveness  of such  registration  statement(s)  so long as any
options covered thereby remain outstanding and unexercised.

                  Section 2.07.   Transfer  Taxes.  PIA Delaware  shall pay any
and all  transfer  taxes  incurred  in  connection  the Merger and the stock and
option issuances and other transactions contemplated hereunder.

forth in the SPAR Disclosure Letter:

                  (a) Each SPAR Party is a corporation  duly organized,  validly
existing and in good standing under the laws of its state of incorporation. Each
SPAR Party is duly  qualified to conduct  business and is in good  standing as a
foreign  corporation in each  jurisdiction  in which the conduct of its business
requires it to be so  qualified,  except  where the  failure to be so  qualified
would  not  have  a  material  adverse  effect  on  the  business,   operations,
properties,  assets or financial  condition of the SPAR Parties taken as a whole
(a "SPAR Material Adverse Effect").

                  (b) As of the date  hereof,  neither  SAI, SIM nor SMI has any
assets  or  liabilities  or has  conducted  any  business  operations  except in
anticipation of and in connection with the SPAR Reorganization  Transactions and
the other  transactions  contemplated by the SPAR  Reorganization  Agreement and
this Agreement.

                  (c) As of the date of this  Agreement,  no SPAR  Party has any

participant in any joint venture,  partnership  or other  non-corporate  entity.
However,  the Parties  acknowledge and understand that immediately  prior to the

names of all  predecessor  companies of each SPAR  Marketing  Company,  (ii) the
names  of all  entities  from  which  any SPAR  Party  previously  acquired  any
significant  assets,  and (iii) all sales (other than in the ordinary  course of
business) and spinoffs of significant assets by any SPAR Marketing Company since

otherwise set forth in the SPAR Disclosure Letter:

                  (a) Each SPAR Party has the  corporate  power,  authority  and
legal  right  to  execute,  deliver  and  perform  (i) the  SPAR  Reorganization

"Merger  Document" and  collectively  the "Merger  Documents").  The  execution,
delivery and performance of the SPAR  Reorganization  Agreement,  this Agreement
and the other  Merger  Documents by each SPAR Party (to the extent it is a party
thereto)  have been duly  authorized by all  necessary  corporate  action and no
further corporate action on the part of any SPAR Party is necessary to authorize
the SPAR  Premerger  Agreements to which it is a party or this  Agreement or any
other  Merger  Document  to  which  it is a  party  or  the  performance  of the
transactions contemplated hereby or thereby .

                  (b) The SPAR Premerger  Agreements and this Agreement (i) have
been duly  executed and delivered on behalf of each SPAR Party (to the extent it
is a party thereto) and (ii) constitute legal, valid and binding  obligations of
such SPAR Party,  enforceable in accordance with their respective terms,  except
as  may  be  limited  by  (A)  applicable  bankruptcy,   insolvency,  fraudulent
conveyance  or  transfer,  reorganization  or other laws  affecting  any rights,
powers, privileges,  remedies and interests of creditors generally, (B) rules or
principles of equity or public policy  affecting the  enforcement of obligations
generally,   whether  at  law,  in  equity  or  otherwise,   including  (without
limitation) those pertaining to materiality, reasonableness,  unconscionability,
impossibility  of  performance,  redemption  or other  cure,  surety  rights  or
defenses, waiver, latches, estoppel, or judicial deference, or (C) discretionary
powers  of any  court  or  other  authority  before  which  may be  brought  any
proceeding seeking equitable or other remedies,  in each case whether at law, in

issued and outstanding capital stock of SAI as of the date of this Agreement and
(ii) the names of each  proposed  SAI Option  Holder and the number of shares of

SIA Option at any time prior to (1) the  mailing of the PIA Proxy  Statement  in
the case of any  individual  whose  present or future  holdings of shares of PIA
Delaware  Stock or options to acquire such shares are disclosed in the PIA Proxy

the SAI Options will be evidenced by a written option agreement, copies of which

authorized and the issued and outstanding capital stock of each other SPAR Party
as of the date of this Agreement.  As of the date of this Agreement,  all of the
issued and outstanding  shares of the capital stock of each SPAR Party are owned
beneficially  and of record by the SPAR  Stockholders in the case of SAI, and by
the SPAR Principals in the case of all other SPAR Parties, free and clear of all
Restrictions  (as  hereinafter  defined),  and have been validly  issued and are

                  (c) Other than the proposed SAI Options or in connection  with
the SPAR Reorganization  Transactions or this Agreement,  as of the date hereof:
(i) there are no outstanding rights, subscriptions, warrants, calls, convertible
securities,  unsatisfied  preemptive rights,  options or other agreements of any
kind pursuant to which any SPAR Party is required to issue any of its authorized
but  unissued  capital  stock;  and  (ii)  no  SPAR  Party  has  any  obligation
(contingent  or  otherwise)  to  purchase,   redeem  or  otherwise  acquire  any
outstanding  shares  of  capital  stock  or to pay  any  dividend  or  make  any
distribution in respect thereof.

                  Section 3.04.   No  Violations.  Except as otherwise set forth

a party  thereto)  do not and will not  violate  or result in the  breach of any
term,  condition  or  provision  of, or require the consent of any other  person
under,  (i) any existing  applicable law,  ordinance,  or  governmental  rule or

respect  under any Material  SPAR  Document,  and to the  knowledge of each SPAR

(i) the combined  balance  sheets of the SPAR  Marketing  Companies at March 31,
1998 (the "Audited SPAR Marketing Balance Sheet Date"),  and March 31, 1997, and
the  related  combined   statements  of  income,   cash  flows  and  changes  in
stockholders'  equity for the fiscal years then ended,  together with the report
of  Ernst  &  Young,   LLP  thereon  (the  "Audited  SPAR  Marketing   Financial
Statements");  (ii) the unaudited (but reviewed)  combined balance sheets of the
SPAR  Marketing  Companies at December  31, 1998 (the  "Interim  SPAR  Marketing
Balance Sheet  Date"),  and the related  combined  statements of income and cash
flows  for the nine  month  period  then  ended  (the  "Interim  SPAR  Marketing
Financial  Statements"  and together with the Audited SPAR  Marketing  Financial
Statements,  the "SPAR Marketing Financial  Statements");  and (iii) the balance
sheets of MCI at December 31, 1998 (the "Audited MCI Balance  Sheet Date"),  and

changes in stockholders'  equity for the fiscal years then ended,  together with
the  report  of  Ernst  &  Young,   LLP  thereon  (the  "Audited  MCI  Financial

SMCI and the  other  pro  forma  adjustments  contemplated  by the MCI  Purchase
Agreement.  The SPAR  Marketing  Financial  Statements  have  been  prepared  in
accordance with generally accepted accounting  principles ("GAAP")  consistently
applied  throughout  the  periods  involved  and  fairly  present  the  combined
financial  position and the combined results of operations of the SPAR Marketing
Companies as of the dates and for the periods indicated,  subject in the case of

to the financial condition of the SPAR Marketing Companies.  To the knowledge of
the SPAR Parties,  based upon such audit,  the Audited MCI Financial  Statements
have been prepared in accordance with GAAP consistently  applied  throughout the
periods  involved and fairly  present the pro forma  financial  position and the
results of operations of MCI as of the dates and for the periods indicated.

                  (b) The Interim SPAR Marketing  Financial  Statements  contain
all adjustments of a normal recurring nature,  based upon historical  operations

present fairly the financial position for the periods then ended.

business (each a "SPAR Permit" and collectively the "SPAR Permits").

                  (b) Each SPAR  Permit is valid and in full  force and  effect,

in the judgment of the SPAR Marketing  Companies in relation to the business and
assets of such SPAR Marketing  Company;  (b) all such policies are in full force
and effect in accordance with their terms,  no notice of  cancellation  has been
received, and to the knowledge of the SPAR Marketing Companies,  with respect to

notice or lapse of time (or both), would constitute a material default under any
such policy;  and (c) no SPAR Marketing  Company has been refused any insurance,
nor has any SPAR  Marketing  Company's  coverage been limited,  by any insurance
carrier to which it has  applied  for  insurance  or with  which it has  carried

                  Section 3.10. Employees.  Except as otherwise set forth in the
SPAR Disclosure  Letter:  (a) there have not been in the past five years and, to

or similar body in any foreign country;  (d) the employees of the SPAR Marketing
Companies are not covered by any collective bargaining  agreement;  and (e) each
SPAR Marketing  Company has paid or properly  accrued in accordance with GAAP in

                  Section 3.11.  Employee Benefit Plans and Arrangements. Except
as otherwise set forth in the SPAR Disclosure Letter:

                  (a) The SPAR  Disclosure  Letter  sets  forth a  complete  and
accurate  list of each  Benefit Plan  covering  any present or former  officers,
employees,  consultants,  or  directors of any SPAR  Marketing  Company (a "SPAR
Benefit  Plan").  As used in this  Agreement:  "ERISA"  shall mean the  Employee
Retirement  Income  Security  Act  of  1974,  as  amended,  and  the  rules  and
regulations promulgated thereunder,  as the same may be supplemented,  modified,
amended,  restated or replaced from time to time; "Pension Plan" of a referenced
party shall mean each  "employee  pension  benefit  plan" (as defined in Section
3(2) of ERISA) of the referenced  party;  "Welfare  Plan" of a referenced  party
shall mean each "employee  welfare  benefit plan" (as defined in Section 3(i) of
ERISA) of the  referenced  party;  "Other ERISA  Benefit" of a referenced  party
shall mean any plan or agreement governed by ERISA or the Code of the referenced
party  relating to deferred  compensation,  bonus and  performance  compensation
(other  than  salesmen  commissions),   stock  purchase,   stock  option,  stock
appreciation,   severance,   vacation,  sick  leave,  holiday  fringe  benefits,
personnel policy,  reimbursement  program,  insurance,  welfare or similar plan,
program,  policy or arrangement;  and "Benefit Plan" of a referenced party shall
mean each Pension Plan,  Welfare Plan and Other ERISA Benefit of the  referenced
party;  in each case to the extent  maintained or contributed to, or required to
be  maintained  or  contributed  to,  by or for  which  there  otherwise  is any
liability as of the Effective  Time, of such party or its respective  affiliates
or any other person or entity that,  together  with such party,  is treated as a
single  employer  under  Section  414(b),  (c),  (m) or (o) of the  Code  (each,
together with such party, a "Commonly Controlled Entity") for the benefit of any
present or former officer, employee, consultant or director.

                  (b) Each SPAR Benefit Plan is in substantial  compliance  with
all reporting, disclosure and other requirements applicable to such SPAR Benefit
Plan. Each SPAR Benefit Plan that is a Pension Plan and intended to be qualified
under  Section  401(a)  of the  Code  (each  a "SPAR  Pension  Plan")  has  been
determined  by the  Internal  Revenue  Service to be so  qualified  and,  to the
knowledge of the SPAR Marketing  Companies,  no condition exists or has occurred
that would  adversely  affect any such  determination.  Neither any SPAR Benefit
Plan, nor any SPAR Marketing Company, nor to the knowledge of any SPAR Marketing
Company any  Commonly  Controlled  Entity of any SPAR  Marketing  Company or any
trustee or agent of any SPAR Benefit Plan,  has been or is presently  engaged in
any prohibited  transactions  as defined by Section 406 of ERISA or Section 4975
of the Code (i) for which an exemption is not applicable,  or (ii) that would be
reasonably likely to subject any SPAR Marketing Company to


                                      -10-

<PAGE>



a  material  amount of tax or penalty  imposed  by  Section  4975 of the Code or
Section 502 of ERISA. To the knowledge of the SPAR Marketing Companies, there is
no event or condition existing that would be deemed a "reportable event" (within
the  meaning  of Section  4043 of ERISA)  with  respect to which the  thirty-day
notice  requirement has not been waived.  To the knowledge of the SPAR Marketing
Companies,  no condition  exists that would be reasonably  likely to subject any
SPAR  Marketing  Company to a material  amount of penalty  under Section 4071 of
ERISA.

                  (c)  Neither  any  SPAR  Marketing  Company  nor any  Commonly
Controlled Entity of any SPAR Marketing Company is or has ever been party to any
"'multi-employer  plan," as that term is defined in Section 3(37) of ERISA. True
and correct  copies of (i) the most recent  annual report (Form 5500 series) and
any  attached  schedules  for each SPAR  Benefit  Plan (if any such  report  was
required by applicable  law), (ii) the most recent summary plan  description for
each SPAR Benefit Plan and (iii) the most recent  determination letter issued by
the Internal  Revenue  Service for each SPAR Pension Plan have been  provided to
PIA Delaware.

                  (d) With  respect  to each  SPAR  Benefit  Plan,  there are no
actions, suits or claims (other than routine claims for benefits in the ordinary
course or relating to qualified  domestic relations orders within the meaning of
Section  414(p) of the Code) pending or, to the knowledge of the SPAR  Marketing
Companies,  overtly threatened against any SPAR Benefit Plan, any SPAR Marketing
Company,  any Commonly  Controlled  Entity of any SPAR Marketing  Company or any
trustee or agent of any SPAR  Benefit  Plan,  nor to the  knowledge  of the SPAR
Marketing Companies, is there any reasonable basis for such claims.

                  (e) With  respect to each SPAR  Benefit Plan to which any SPAR
Marketing  Company  or any  Commonly  Controlled  Entity  of any SPAR  Marketing
Company is a party which  constitutes  a group  health  plan  subject to Section
4980B of the Code, each such SPAR Benefit Plan  substantially  complies,  and in
each  case has  substantially  complied,  with all  applicable  requirements  of
Section 4980B of the Code. There is no outstanding  material  liability  (except
for  premiums  that  have not  become  overdue)  or  other  accrued  but  unpaid
obligations  under Title IV of ERISA with respect to any SPAR Pension Plan,  and
no  condition  exists  that would be  reasonably  expected to result in any SPAR
Marketing Company incurring a material liability under Title IV of ERISA, either
directly or with respect to any Commonly Controlled Entity of any SPAR Marketing
Company.  All premiums payable to the Pension Benefit Guaranty  Corporation (the
"PBGC") have been paid prior to becoming overdue.  Neither the PBGC nor any SPAR
Marketing  Company  nor any  Commonly  Controlled  Entity of any SPAR  Marketing
Company has  instituted  proceedings  to terminate any SPAR Pension Plan that is
subject to Title IV of ERISA,  and the PBGC has not informed any SPAR  Marketing
Company of its intent to institute  proceedings to terminate any such plan. Full
payment  has been made of all  amounts  that any SPAR  Marketing  Company or any
Commonly  Controlled  Entity of any SPAR Marketing  Company was required to have
paid as a  contribution  to any SPAR Pension Plan that is subject to Title IV of
ERISA  (with  applicability  determined  as of the last  day of the most  recent
fiscal  year of each of the SPAR  Pension  Plans ended prior to the date of this
Agreement),  and none of the SPAR Pension Plans has incurred any material amount
of  "accumulated  funding  deficiency"  (as  defined in Section 302 of ERISA and
Section 412 of the Code),  whether or not waived, as of the last day of the most
recent  fiscal  year of each such SPAR  Pension  Plan ended prior to the date of
this Agreement.

                  (f) No SPAR Pension Plan is a defined  benefit  pension  plan.
Each SPAR Benefit Plan is, and its  administration  is and at all times has been
in substantial  compliance with, and no SPAR Marketing  Company has received any
claim or notice that any such SPAR Benefit Plan is not in substantial compliance
with, its terms and all Applicable Laws,  including without  limitation,  to the
extent  applicable,  the  requirements  of ERISA and the Code. No SPAR Marketing
Company and no Commonly  Controlled  Entity of any SPAR Marketing  Company is in
default in any material respect in performing any of its contractual obligations
under  any  SPAR  Benefit  Plan or any  related  trust  agreement  or  insurance
contract. There are no material outstanding liabilities of any SPAR Benefit Plan
other than  liabilities  for  benefits  to be paid to  participants  in any SPAR
Benefit Plan and their  beneficiaries  in accordance with the terms of such SPAR
Benefit Plan. Each SPAR Benefit Plan may be amended or modified or terminated by
the applicable SPAR Marketing Company or a Commonly  Controlled Entity of a SPAR
Marketing Company at any time without liability except under any defined pension
benefit  plan.  No SPAR  Benefit Plan other than a SPAR  Pension  Plan,  retiree
medical  plan or  severance  plan  provides  benefits  to any  individual  after
termination of employment.

                  (g) The consummation of the  transactions  contemplated by the
SPAR Premerger  Agreements and this Agreement will not: (A) entitle any employee
of any SPAR Marketing Company to severance pay, unemployment compensation or any
other  payment or benefit;  (B)  accelerate  the time of payment or vesting,  or
increase the amount of compensation due to any such employee;  (C) result in any
liability under Title IV of ERISA;


                                      -11-

<PAGE>



(D) result in any  prohibited  transaction  described in Section 406 of ERISA or
Section 4975 of the Code for which an exemption is not available;  or (E) result
(either alone or in  conjunction  with any other event) in the payment or series
of payments by any SPAR Marketing Company or any of its affiliates to any person
of an "excess parachute payment" within the meaning of Section 280G of the Code.

                  (h) With  respect  to each  SPAR  Benefit  Plan that is funded
wholly or  partially  through  an  insurance  policy,  all  material  amounts of
premiums required to have been paid to date under the insurance policy have been
paid, all material  amounts of premiums  required to be paid under the insurance
policy  through  the  Closing  Date will have been paid on or before the Closing
Date and, as of the Closing Date,  there will be no material amount of liability
of any SPAR  Marketing  Company or any  Commonly  Controlled  Entity of any SPAR
Marketing Company under any insurance policy or ancillary agreement with respect
to such insurance policy in the nature of a retroactive  rate  adjustment,  loss
sharing  arrangement or other actual or contingent  liability  arising wholly or
partially out of events occurring prior to the Closing Date.

                  (i) Each SPAR Benefit Plan that constitutes a "welfare benefit
plan" (within the meaning of Section 3(i) of ERISA) for which  contributions are
claimed by any SPAR Marketing  Company or any Commonly  Controlled Entity of any
SPAR  Marketing  Company as  deductions  under any  provision  of the Code is in
material  compliance  with  all  applicable   requirements  pertaining  to  such
deduction.  With respect to any "welfare  benefit  fund"  (within the meaning of
Section 419 of the Code)  related to such a welfare  benefit  plan,  there is no
disqualified  benefit  (within the meaning of Section  4976(b) of the Code) that
would result in the  imposition of a tax under Section  4976(a) of the Code. All
welfare benefit funds intended to be exempt from tax under Section 501(a) of the
Code have been determined by the Internal Revenue Service to be so exempt and no
event or condition  exists or has occurred which would adversely affect any such
determination.

                  (j) No SPAR Marketing  Company has any Benefit Plan outside of
the United States.

                  (k) All persons  classified by any SPAR  Marketing  Company as
independent  contractors  or "leased  employees"  within the  meaning of Section
414(n)  of the Code  ("SPAR  Leased  Employees")  satisfy  and have at all times
satisfied the  requirements  of applicable  law to be so  classified.  Each SPAR
Marketing  Company has fully and accurately  reported their  compensation on IRS
Forms 1099 when required to do so. No SPAR Marketing  Company has any obligation
to provide benefits with respect to such independent  contractors or SPAR Leased
Employees under any SPAR Benefit Plan or otherwise.

                  Section  3.12.  Compliance  with Law.  Except as otherwise set
forth in the SPAR Disclosure Letter: each SPAR Marketing Company has complied in
all material respects with each, and is not in violation in any material respect
of,  any  Applicable  Law to  which  such  SPAR  Marketing  Company's  business,

                  (a)  All  federal,  state,  local  and  foreign  tax  returns,
reports,  statements and other similar filings  required to be filed by any SPAR
Marketing Company (the "SPAR Tax Returns") with respect to any material federal,
state, local or foreign taxes, assessments,  interest, penalties,  deficiencies,
fees and other governmental charges or impositions (including without limitation
all  income  tax,   unemployment   compensation,   social   security,   payroll,
withholding,  sales and use, excise, privilege, property, ad valorem, franchise,
license,  school and any other tax or similar governmental charge or imposition,
and interest and  penalties  therein,  under the  Applicable  Laws of the United
States or any state or Municipal or political subdivision thereof or any foreign
country or political  subdivision  thereon ("Taxes") have been timely filed with
the appropriate  governmental  agencies in all  jurisdictions in which such SPAR
Tax  Returns are  required to be filed,  and all such SPAR Tax Returns are true,
complete and correct in all material respects and fairly reflect the liabilities
of the SPAR  Marketing  Companies for Taxes for the periods,  property or events
covered thereby.

                  (b) All Taxes, including (without limitation) those called for
by the SPAR Tax Returns,  required to be paid or withheld by any SPAR  Marketing
Company and any  deficiency  assessments,  penalties  and  interest  for which a
notice of assessment has been received  (other than as may have been settled and
paid in full in accordance therewith,  and other than those being contested,  if
any,  as set  forth in the SPAR  Disclosure  Letter)  have been  timely  paid or
withheld.

                  (c) The  accruals  for Taxes  contained  in the  Interim  SPAR
Marketing  Financial  Statements  for the Tax  liabilities of the SPAR Marketing
Companies  have been made in  accordance  with GAAP as of that date and  include
adequate  provision  under GAAP for all  deferred  Taxes  (other than  necessary
increments  due to the passage of time),  except that no accruals have been made
for income Taxes for SINC and SBRS,  which are Subchapter S  corporations  under
the Code. SMF utilizes the accrual method of accounting for income tax purposes,
SINC and SBRS utilize the cash method of accounting for income tax purposes, and
none of them has changed its method of accounting for income tax purposes in the
past five years.  Each SPAR  Marketing  Company  that has filed SPAR Tax Returns
under  Subchapter S of the Code has made a timely and  effective  election to be
taxed under the  provisions  of Subchapter S of the Code and has at no time been
taxable under the provisions of Subchapter C of the Code. No such SPAR Marketing
Company has any net unrealized built-in gain that has not been recognized within
the meaning of Section 1374 of the Code.

                  (d) No SPAR Marketing  Company is or has at any time ever been
a party to a Tax sharing, Tax indemnity or Tax allocation agreement, and no SPAR
Marketing  Company has assumed any Tax  liability  of any other person or entity
under contract.

                  (e) No SPAR  Marketing  Company  has  received  any  notice of
assessment or proposed assessment in connection with any SPAR Tax Returns, other
than as may have been  settled  and paid in full in  accordance  therewith,  and
there are no pending tax examinations of or material tax claims asserted against
any SPAR Marketing Company or any of its assets or properties. No SPAR Marketing
Company has extended,  or waived the  application of, any statute of limitations
of any jurisdiction regarding the assessment or collection of any Taxes.

                  (f)  There  are  now,  and  as of  immediately  following  the
Effective  Time there will be, no liens  (other  than any lien for Taxes not yet
overdue and payable) on any of the assets or  properties  of any SPAR  Marketing
Company  relating to or  attributable  to Taxes.  To the  knowledge  of the SPAR
Marketing Companies, there is no reasonable basis for the assertion of any claim
relating to or attributable to Taxes that, if adversely determined, would result
in any lien on the assets of any SPAR Marketing Company or otherwise have a SPAR
Material Adverse Effect.

                  (g) None of the SPAR Marketing  Companies has any knowledge of
any reasonable  basis for any additional  assessment of any Taxes for any period
ending on or before the  Closing  Date (other  than  increased  Taxes based upon
increased  business  units,  business sites,  payroll,  profits or other taxable
attribute  relating to an expanding  enterprise  prior to the Closing Date). All
Tax payments related to employees, including income tax withholding, FICA, FUTA,
unemployment  and  worker's  compensation,  required  to be  made  by  the  SPAR
Marketing  Companies,  have been fully and properly paid,  withheld,  accrued or
recorded.

                  Section 3.16.   Intellectual  Property  Matters.   Except  as
otherwise set forth in the SPAR Disclosure Letter:

                  (a)  The  SPAR  Disclosure  Letter  sets  forth  all  patents,
trademarks,  trade names, service marks,  copyrights,  software,  material trade
secrets or material know-how owned or used in any material respect by any


                                      -13-

<PAGE>
SPAR  Marketing  Company in the conduct of its business (the "SPAR  Intellectual
Property"),  excluding,  however,  all readily  commercially  available software
programs licensed to a SPAR Marketing Company (for example,  without limitation,
Windows,   Windows  NT,  MS  Word,  MS  Excel,  and  MS  Explorer)  ("Commercial
Software"),  which  Commercial  Software need not be set forth on such schedule.
All of the SPAR  Intellectual  Property is (or will be as of the Effective Time)
owned by or  licensed  to STM or one of the SPAR  Marketing  Companies  free and
clear of any liens (except insofar as a license or the  restrictions  thereunder
may  constitute  a lien,  and except  for the SPAR  Trademark  Licenses  and the
Business  Manager  Agreement).  At or before the  Closing,  (i) SIT and SMS will
enter into  non-exclusive  perpetual  royalty free licenses with STM  respecting
their use of the name "SPAR" and certain  other  trademarks  and related  rights
owned or to be owned by STM (the "SPAR Trademark Licenses") such agreement to be
substantially  in the form  attached as Exhibit C hereto,  and (ii) SMF, SMS and
SIT will enter into a Software Ownership  Agreement with respect to the Internet
job scheduling  software (called "Business Manager") jointly developed and owned
by them,  such agreement to be  substantially  in the form attached as Exhibit D
hereto (the "Business Manager Agreement").

                  (b)  There  are no  ongoing  royalty,  commission  or  similar
arrangements, and no licenses, sublicenses or agreements from any SPAR Marketing
Company as a licensor,  pertaining  to the current use of the SPAR  Intellectual
Property,  except as may be applicable under the Commercial  Software,  the SPAR
Trademark Licenses and the Business Manager Agreement.

                  (c) No SPAR Marketing  Company infringes upon or unlawfully or
wrongfully uses any patent,  trademark,  trade name, service mark,  copyright or
trade secret owned or claimed by any other  person or entity.  No action,  suit,
proceeding or investigation has been instituted or, to the knowledge of the SPAR
Marketing  Companies,  overtly  threatened  relating to any, patent,  trademark,
trade name,  service mark,  copyright or trade secret formerly or currently used
by any SPAR Marketing Company. None of the SPAR Intellectual Property is subject
to any  outstanding  order,  decree or judgment.  No SPAR Marketing  Company has
agreed to indemnify any person or entity for or against any  infringement  of or
by the SPAR Intellectual Property. Except for (i) the SPAR Intellectual Property
licensed or to be licensed to SMS and SIT by STM,  (ii) the common  ownership of
the  software  reflected  in the  Business  Manager  Agreement,  and  (iii)  the
ownership of and director and officer positions in the SPAR Marketing Companies,
SGI, SMS, SIT, STM and the SPAR  Parties,  no present or former  employee of any
SPAR  Marketing  Company,  and no person or entity other than SGI, SMS, SIT, STM
and the SPAR  Parties  (and the  SPAR  Principals  solely  as the  officers  and
shareholders  thereof),  directly  or  indirectly  owns or has any  proprietary,
financial  or other  interest  in,  in whole or in part,  any SPAR  Intellectual
Property.

                  (d) All SPAR  Intellectual  Property  in the form of  computer
software that is utilized by any SPAR Marketing  Company in the operation of its
business is capable of processing date data between and within the twentieth and
twenty-first  centuries or can be rendered capable of processing such data prior
to the date  necessary to avoid  disruption  of its  business by  utilizing  the
employees of one or more of the SPAR Marketing Companies in the normal course of
business and by  expenditure  of not more than $100,000 in excess of the cost of
software purchased for reasons other than the failure of existing software to be
capable of such processing.

                  Section 3.17.    Existing  Condition.  Except as otherwise set
forth in the SPAR Disclosure  Letter,  since the Interim SPAR Marketing  Balance
Sheet Date, no SPAR Marketing Company has:

(a)      incurred  any  liabilities,  other  than  liabilities  incurred  in the
         ordinary course of business  consistent with past practice  (including,
         without  limitation,  advances  under  its  commitments  and  lines  of
         credit),   the  liabilities   contemplated  under  the  SPAR  Premerger
         Agreements;

(b)      discharged   or  satisfied  any  lien  or   encumbrance   or  paid  any

         commitments  and lines of credit),  or failed to pay or discharge  when
         due any  liabilities,  other than in the  ordinary  course of  business
         consistent  with  past  practice,  or  where  the  obligation  is being
         contested in good faith,  and the failure to pay or  discharge  has not
         caused and would not be  reasonably  likely to cause any SPAR  Material
         Adverse Effect;

(c)      sold,  encumbered,  assigned or transferred  any assets,  properties or
         rights or any interest therein,  or made any agreement or commitment or

         assets,  properties  or rights  of any SPAR  Marketing  Company  or any
         interest  therein,  except for sales and  dispositions  in the ordinary
         course of business  consistent  with past practice,  and except for the
         transactions  contemplated under the SPAR Premerger Agreements and this
         Agreement;

         or acquire  any of shares of its capital  stock or its other  ownership
         interests;

                                   ARTICLE IV

                REPRESENTATIONS AND WARRANTIES OF THE PIA PARTIES

                  Except as otherwise  disclosed in that certain  letter of even
date herewith delivered to the SPAR Parties prior to the execution hereof (which
letter shall contain appropriate references and cross references to identify the
Sections  hereof to which the  information  in such  letter  relates)  (the "PIA
Disclosure  Letter"),  each PIA Party,  jointly and  severally,  represents  and
warrants to the SPAR Parties as follows:

                  Section 4.01.    Corporate  Existence.   Except  as  otherwise
disclosed in the PIA Disclosure Letter:

                  (a) Each PIA Party is a corporation  duly  organized,  validly
existing and in good standing under the laws of its state of incorporation.  PIA
Delaware  has no  subsidiaries  other than PIA  California.  The PIA  Disclosure
Letter  sets  forth  a  complete  list  of the  subsidiaries  of PIA  California
(individually,  a "PIA Subsidiary" and collectively, the "PIA Subsidiaries") and
the owner of each.

                  (b) Each  PIA  Subsidiary  is a  corporation  duly  organized,
validly  existing and in good standing under the laws of the jurisdiction of its
incorporation.  PIA  Delaware,  PIA  California,  and the PIA  Subsidiaries  are
sometimes   collectively  referred  to  individually  as  a  "PIA  Company"  and
collectively as the "PIA Companies".

                  (c) Each PIA Company is duly qualified to conduct business and
is in good standing as a foreign  corporation in each  jurisdiction in which the
conduct of its business requires it to be so qualified, except where the failure
to be so qualified  would not have a material  adverse  effect on the  business,
operations, properties, assets or financial condition of the PIA Companies taken
as a whole (a "PIA Material Adverse Effect").

                  (d) As of the date of this Agreement,  except to the extent it
is the sole  stockholder of another PIA Company,  no PIA Company owns, of record

                  (c) This  Agreement  has been duly  executed and  delivered on

of each PIA Party,  enforceable in accordance  with its terms,  except as may be

"Proposed PIA  Certificate of Amendment"),  which (among other things)  provides
for an  increase in the  authorized  number of shares of PIA  Delaware  Stock to

                  (c) No PIA Company, and to the knowledge of each PIA Party, no

under the HSR Act and in connection with or in compliance with the provisions of
the Securities Act and the Exchange Act, no  authorization,  approval or consent

collectively the "PIA Permits").

                  (b) Each PIA  Permit is valid and in full force and effect and
no PIA Permit will be terminated  or impaired in any material  respect or become

                  Section 4.08.  Contracts and  Commitments.  The PIA Disclosure
Letter  sets  forth an  accurate,  correct  and  complete  list of all  material

oral, including all amendments and supplements thereto, of each PIA Company (the
"PIA  Contracts"),  to which any PIA Company is a party or is bound, or by which

         with any  present  or  former  (within  the past  two  years)  officer,

                  Section 4.09. Insurance.  Except as otherwise disclosed in the
PIA  Disclosure  Letter:  (a) the assets,  properties and operations of each PIA
Company are  insured  under  various  policies  of general  liability,  workers'
compensation  and other forms of insurance in amounts  which are adequate in the
judgment of the PIA Companies in relation to the business and assets of such PIA
Company;  (b) all such policies are in full force and effect in accordance  with
their terms, no notice of cancellation has been received and to the knowledge of
the PIA  Companies  with  respect to any such  policy,  and there is no existing
default or event that with the giving of notice or lapse of time (or both) would
constitute a material default under any such policy;  and (c) no PIA Company has
been refused any insurance,  nor has any Company's coverage been limited, by any
insurance  carrier to which it has  applied for  insurance  or with which it has
carried insurance during the past five years.

                  Section 4.10. Employees.  Except as otherwise disclosed in the
PIA  Disclosure  Letter:  (a) there have not been in the past five years and, to
the  knowledge  of the PIA  Parties,  there are not  pending,  any  organized or
coordinated labor disputes, work stoppages, requests for representation, pickets
or work  slow-downs due to labor  disagreements;  (b) there are and have been no
unresolved material violations of any laws of any Governmental Entity respecting
the employment of any employees;  (c) there is no unfair labor practice,  charge
or  complaint  pending,  unresolved  or, to the  knowledge  of the PIA  Parties,
overtly  threatened that would be reasonably  likely to be brought or filed with
the National Labor Relations Board or similar body in any foreign  country;  (d)
the PIA Disclosure Letter describes each collective  bargaining  agreement which
covers any  employees of any PIA  Company;  and (e) each PIA Company has paid or
properly  accrued in accordance with GAAP in the ordinary course of business all
wages and  compensation  due to  employees,  including all vacations or vacation

                  Section 4.11.    Employee  Benefit  Plans  and   Arrangements.
Except as otherwise disclosed in the PIA Disclosure Letter:

                  (a) The PIA  Disclosure  Letter  sets  forth  a  complete  and
accurate  list of each  Benefit Plan  covering  any present or former  officers,
employees,  consultants or directors of any PIA Company (a "PIA Benefit  Plan").
ERISA,  Benefit Plan, Welfare Plan, Pension Plan and Commonly  Controlled Entity
are defined in Section 3.11.

                  (b) Each PIA Benefit Plan is in  substantial  compliance  with
all reporting,  disclosure and other requirements applicable to such PIA Benefit
Plan.  Each PIA Benefit Plan that is a Pension  Plan (a "PIA Pension  Plan") and
that is intended to be  qualified  under  Section  401(a) of the Code,  has been
determined  by the  Internal  Revenue  Service to be so  qualified  and,  to the
knowledge of the PIA Parties,  no  condition  exists or has occurred  that would
adversely  affect any such  determination.  Neither any PIA Benefit Plan nor any
PIA Company,  nor to the  knowledge  of any PIA Company any Commonly  Controlled
Entity of any PIA Company or any trustee or agent of any PIA Benefit  Plan,  has
been or is  presently  engaged  in any  prohibited  transactions  as  defined by
Section 406 of ERISA or Section  4975 of the Code for which an  exemption is not
applicable  which  would be  reasonably  likely to subject  any PIA Company to a
material amount of tax or penalty imposed by Section 4975 of the Code or Section
502 of  ERISA.  To the  knowledge  of the PIA  Companies,  there  is no event or
condition existing that would be deemed a "reportable event" (within the meaning
of  Section  4043  of  ERISA)  with  respect  to  which  the  thirty-day  notice
requirement  has not  been  waived.  To the  knowledge  of the PIA  Parties,  no
condition exists that would be reasonably likely to subject any PIA Company to a
material amount of penalty under Section 4071 of ERISA.

                  (c) Neither any PIA Company nor any Commonly Controlled Entity
of any PIA Company is or has ever been party to any  "'multi-employer  plan," as
that term is defined in Section 3(37) of ERISA.  True and correct  copies of (i)
the most recent annual report (Form 5500 series) and any attached  schedules for
each PIA Benefit Plan (if any such report was required by applicable  law), (ii)
the most recent summary plan description for each PIA Benefit Plan and (iii) the
most recent determination letter issued by the Internal Revenue Service for each
PIA Pension Plan have been provided to the SPAR Parties.

                  (d)  With  respect  to each PIA  Benefit  Plan,  there  are no
actions, suits or claims (other than routine claims for benefits in the ordinary
course or relating to qualified  domestic relations orders within the meaning of
Section  414(p) of the Code)  pending or, to the  knowledge  of the PIA Parties,
overtly threatened  against any PIA Benefit Plan, any PIA Company,  any Commonly
Controlled  Entity of any PIA Company or any trustee or agent of any PIA Benefit
Plan, nor to the knowledge of the PIA Parties is there any reasonable  basis for
such claims.

                  (e) With  respect  to each PIA  Benefit  Plan to which any PIA
Company or any  Commonly  Controlled  Entity of any PIA Company is a party which
constitutes a group health plan subject to Section 4980B


                                      -21-

<PAGE>



of the Code, each such PIA Benefit Plan substantially complies, and in each case
has substantially complied, with all applicable requirements of Section 4980B of
the Code. There is no outstanding  material  liability (except for premiums that
have not become overdue) or other accrued but unpaid  obligations under Title IV
of ERISA with respect to any PIA Pension Plan and no condition exists that would
be  reasonably  expected  to  result in any PIA  Company  incurring  a  material
liability  under  Title IV of ERISA,  either  directly  or with  respect  to any
Commonly Controlled Entity of any PIA Company.  All premiums payable to the PBGC
have been paid when due.  Neither the PBGC nor any PIA Company nor any  Commonly
Controlled Entity of any PIA Company has instituted proceedings to terminate any
PIA  Pension  Plan  that is  subject  to Title IV of ERISA  and the PBGC has not
informed any PIA Company of its intent to institute proceedings to terminate any
such plan. Full payment has been made of all amounts that any PIA Company or any
Commonly  Controlled  Entity of any PIA Company  was  required to have paid as a
contribution  to any PIA Pension Plan that is subject to Title IV of ERISA (with
applicability  determined  as of the last day of the most recent  fiscal year of
each of the PIA Pension  Plans ended prior to the date of this  Agreement),  and
none of any PIA Pension Plans has incurred any "accumulated  funding deficiency"
(as defined in Section 302 of ERISA and Section 412 of the Code), whether or not
waived,  as of the last  day of the most  recent  fiscal  year of each  such PIA
Pension Plan ended prior to the date of this Agreement.

                  (f) To  the  knowledge  of  the  PIA  Parties,  the  actuarial
assumptions  utilized,  where  appropriate,  in connection with  determining the
funding of each PIA Pension Plan that is a defined  benefit pension plan (as set
forth in the actuarial report for such PIA Pension Plan) are reasonable.  Copies
of the most recent  actuarial  reports have been  furnished to the SPAR Parties.
Based on such actuarial assumptions,  as of the PIA Balance Sheet Date, the fair
market value of the assets or  properties  held under each such PIA Pension Plan
exceeds the actuarially determined present value of all accrued benefits of such
PIA Pension Plan (whether or not vested)  determined on an ongoing  basis.  Each
PIA  Benefit  Plan is,  and its  administration  is and at all times has been in
substantial compliance with, and no PIA Company has received any claim or notice
that any such PIA Benefit Plan is not in substantial  compliance with, its terms
and all Applicable Laws, including without limitation, to the extent applicable,
the  requirements  of  ERISA  and  the  Code.  No PIA  Company  and no  Commonly
Controlled  Entity of any PIA Company is in default in any  material  respect in
performing any of its contractual  obligations under any PIA Benefit Plan or any
related trust agreement or insurance contract. There are no material outstanding
liabilities  of any PIA Benefit Plan other than  liabilities  for benefits to be
paid to  participants  in such PIA  Benefit  Plan  and  their  beneficiaries  in
accordance with the terms of such PIA Benefit Plan. Each PIA Benefit Plan may be
amended or modified or  terminated by the  applicable  PIA Company or a Commonly
Controlled  Entity of a PIA Company at any time without  liability  except under
any defined  pension  benefit plan. No PIA Benefit Plan other than a PIA Pension
Plan, retiree medical plan or severance plan provides benefits to any individual
after termination of employment.

                  (g) The consummation of the transactions  contemplated by this
Agreement will not (A) entitle any employee of any PIA Company to severance pay,
unemployment  compensation  or any other payment or benefit;  (B) accelerate the
time of payment or vesting,  or increase the amount of  compensation  due to any
such employee;  (C) result in any liability under Title IV of ERISA;  (D) result
in any prohibited  transaction described in Section 406 of ERISA or Section 4975
of the Code for which an exemption is not available; or (E) result (either alone
or in conjunction  with any other event) in the payment or series of payments by
any PIA Company or any of its  affiliates to any person of an "excess  parachute
payment" within the meaning of Section 280G of the Code.

                  (h) With  respect  to each PIA  Benefit  Plan  that is  funded
wholly or  partially  through  an  insurance  policy,  all  material  amounts of
premiums required to have been paid to date under the insurance policy have been
paid, all material  amounts of premiums  required to be paid under the insurance
policy  through  the  Closing  Date will have been paid on or before the Closing
Date and, as of the Closing Date,  there will be no material amount of liability
of any PIA Company or any Commonly  Controlled  Entity of any PIA Company  under
any  insurance  policy or ancillary  agreement  with  respect to such  insurance
policy in the nature of a retroactive rate adjustment,  loss sharing arrangement
or other actual or  contingent  liability  arising  wholly or  partially  out of
events occurring prior to the Closing Date.

                  (i) Each PIA Benefit Plan that  constitutes a "welfare benefit
plan," within the meaning of Section 3(i) of ERISA, for which  contributions are
claimed by any PIA Company or any Commonly  Controlled Entity of any PIA Company
as deductions  under any provision of the Code, is in material  compliance  with
all applicable  requirements  pertaining to such deduction.  With respect to any
welfare  benefit fund (within the meaning of Section 419 of the Code) related to
a welfare benefit plan, there is no disqualified  benefit (within the meaning of
Section  4976(b) of the Code) that would result in the imposition of a tax under
Section  4976(a) of the Code.  All welfare  benefit funds  intended to be exempt
from tax under Section 501(a) of the Code have been determined by the


                                      -22-

PIA Tax Returns are required to be filed, and all such PIA Tax Returns are true,
complete  and  correct  in  all  material  respects  and  properly  reflect  the
liabilities  of the PIA Companies for Taxes for the periods,  property or events
covered thereby.

                  (b) All Taxes, including (without limitation) those called for
by the PIA Tax  Returns,  required to be paid or withheld by any PIA Company and
any  deficiency  assessments,  penalties  and  interest  for  which a notice  of
assessment  has been  received  (other than as may have been settled and paid in
full in accordance  therewith) and other than those being contested,  if any, as
set forth in the PIA Disclosure Letter, have been timely paid or withheld.


                  (c) The  accruals  for Taxes  contained  in the PIA  Financial

there is

                                      -23-
<PAGE>

no reasonable  basis for the assertion of any claim relating to or  attributable
to Taxes that, if adversely  determined,  would result in any lien on the assets
of any PIA Company or otherwise have a PIA Material Adverse Effect.

                  (e)  None  of the  PIA  Companies  has  any  knowledge  of any
reasonable  basis for any  additional  assessment  of any  Taxes for any  period
ending on or before the  Closing  Date (other  than  increased  Taxes based upon
increased  business  units,  business sites,  payroll,  profits or other taxable
attribute  relating to an expanding  enterprise  prior to the Closing Date). All
Tax payments related to employees, including income tax withholding, FICA, FUTA,

have been fully and properly paid, withheld, accrued or recorded.

                  Section 4.16.    Intellectual  Property  Matters.   Except  as
otherwise disclosed in the PIA Disclosure Letter:

                  (a)  The  PIA  Disclosure   Letter  sets  forth  all  patents,
trademarks,  trade names, service marks,  copyrights,  software,  material trade
secrets or material  know-how  owned or used in any material  respect by any PIA
Company  in the  conduct  of its  business  (the "PIA  Intellectual  Property"),
excluding,  however, all Commercial Software, which Commercial Software need not
be set forth on such schedule.  All of the PIA Intellectual Property is owned by
or  licensed  to one of the PIA  Companies  free and clear of any liens  (except
insofar as a license or the restrictions thereunder may constitute a lien).

                  (b)  There  are no  ongoing  royalty,  commission  or  similar
arrangements,  and no licenses,  sublicenses or agreements, from any PIA Company
as licensor,  pertaining  to the current use of the PIA  Intellectual  Property,
except as may be applicable under the Commercial Software.

                  (c) No PIA Company  infringes upon or unlawfully or wrongfully
uses any patent, trademark,  trade name, service mark, copyright or trade secret
owned or claimed by any other person or entity. No action,  suit,  proceeding or
investigation  has been  instituted  or, to the  knowledge  of the PIA  Parties,
overtly threatened relating to any, patent, trademark, trade name, service mark,
copyright or trade secret formerly or currently used by any PIA Company. None of
the PIA  Intellectual  Property is subject to any outstanding  order,  decree or
judgment.  No PIA  Company has agreed to  indemnify  any person or entity for or
against any infringement of or by the PIA Intellectual  Property.  No present or
former employee of any PIA Company and no other person or entity owns or has any
proprietary,  financial or other  interest,  direct or indirect,  in whole or in
part, in any patent, trademark, trade name, service mark or copyright, or in any
application  therefor,  or in any  trade  secret,  which any PIA  Company  owns,
possesses or uses in its operations as now or heretofore conducted.

                  (d) All PIA  Intellectual  Property  in the  form of  computer
software that is utilized by any PIA Company in the operation of its business is
capable  of   processing   date  data  between  and  within  the  twentieth  and
twenty-first  centuries or can be rendered capable of processing such data prior
to the date  necessary to avoid  disruption  of its  business by  utilizing  the
employees of one or more of the PIA  Companies in the normal  course of business
and by  expenditure  of not more than $100,000 in excess of the cost of software
purchased for reasons other than the failure of existing  software to be capable
of such processing.

                  Section 4.17.    Existing   Condition.   Except  as  otherwise
disclosed in the PIA Disclosure Letter, since the PIA Balance Sheet Date, no PIA

         ordinary course of business consistent with past practice;

(b)      discharged   or  satisfied  any  lien  or   encumbrance   or  paid  any

         liabilities,  other than in the ordinary course of business  consistent
         with past practice,  or where the obligation is being contested in good
         faith, and the failure to pay or discharge has not caused and would not
         be reasonably likely to cause any PIA Material Adverse Effect;

(c)      sold,  encumbered,  assigned or transferred  any assets,  properties or
         rights or any interest therein,  or made any agreement or commitment or
         granted  any option or right  with,  of or to any person to acquire any
         assets,  properties  or  rights  of any  PIA  Company  or any  interest
         therein,  except for sales and  dispositions  in the ordinary course of
         business  consistent with past practice and except for the transactions

                  Section 5.09.   Notification of Certain Matters.

                  (a) Each Party shall give prompt notice to each other Party of
(i) the  occurrence  or  non-occurrence  of any event  known to such Party which
would be likely to cause any  representation or warranty of such Party contained
in this Agreement to be untrue or inaccurate in any material respect at or prior
to the  Closing  Date,  and (ii) any  failure  of such  Party to comply  with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
such Party hereunder in any material respect.

                  (b) Each Party shall have the continuing  obligation until the
Closing Date to supplement or amend promptly its Disclosure  Letter delivered to
the other Party group with respect to any matter hereafter arising or discovered
that,  if  existing  or known at the date of this  Agreement,  would  have  been
required to have been set forth or described in such Disclosure  Letter (in each
case,  "Amended  Disclosure") in order that the corresponding  representation or
warranty would not have been untrue in any material  respect,  which may include
supplemental disclosure to a representation or warranty with respect to which no
disclosure was made previously.  Any Amended  Disclosure that would constitute a
failure to satisfy the condition precedent set forth in Section 6.02(a),  (b) or
(c) or in Section 6.03(a), (b) or (c) shall not be effective unless consented to
in the sole  discretion of the other Party group (i.e., by SPAR in the case of a
failure to satisfy Section  6.02(a),  (b) or (c) and by PIA Delaware in the case
of a failure to satisfy Section 6.03(a), (b) or (c)). To the extent such consent
is obtained,  or to the extent the condition  precedent is waived on the Closing
Date, the Amended Disclosure shall be deemed effective.

                  Section  5.10.  Closing Net Worth.  The SPAR Parties shall use
their reasonable best efforts to ensure that the Closing Net Worth (as such term
is defined in Section  7.01) is not less than the Target Amount (as such term is
defined in Section 7.01(b) hereof).

                  Section 5.11.    Post Merger  Indemnification  of Officers and
Directors by Parties.

                  (a) For a period of six years  following  the Closing Date, no
PIA Party will (or will permit any other PIA Company to) and no SPAR Party will,
amend, repeal or limit in any way the provisions limiting the personal liability
of any  present  or former  director,  officer,  employee  or agent  (and  their
respective  heirs  and  assigns)  of any PIA  Company  or any  SPAR  Party  (the
"Indemnified  Parties"),  as set forth in the  certificate of  incorporation  or
by-laws or such company or party as of the date of this Agreement.  In addition,
for a period of six years following the Closing Date, the PIA Parties shall, and
shall cause each of the other PIA Companies to, indemnify, to the fullest extent
permitted by  applicable  law,  (i) the  directors of each PIA Company as of the
date of this  Agreement,  (ii) any  persons who served as  directors  of any PIA
Company  prior to the date of this  Agreement,  (iii) all  officers  holding the
title of Senior Vice  President or any higher  office with any PIA Company as of
the date of this  Agreement,  in each case from and  against any and all amounts
for which an employee may be  indemnified  under the corporate laws of its state
of  incorporation.  Without limiting the generality of the foregoing,  costs and
expenses  (including  reasonable  attorney's fees and expenses) incurred by such
indemnified person shall be advanced to or on behalf such indemnified person (in
advance of any final disposition of such matter) if such indemnified  person (A)
agrees in writing with the  indemnitor  to repay all such  advances in the event
that  it is  ultimately  determined  that  he or  she is not  entitled  to  such
indemnification  hereunder or under applicable law, and (B) furnishes reasonable
documentation with respect to such amounts.

                  (b) This Section is expressly  intended to benefit each of the
Indemnified Parties (each of whom shall be entitled to enforce the provisions of
this Section).

                  (c) For a period of six years  following the Closing Date, the
PIA Parties and the SPAR  Parties  shall  cause to be  maintained  in effect the
current policies of directors' and officers' liability  insurance  maintained as
of the Closing Date (or substitute policies with reputable and financially sound
carriers  of at  least  the same  coverage  and  amounts  containing  terms  and
conditions  which are not materially  less  advantageous  in the aggregate) with
respect to claims  arising from or related to facts or events which  occurred at
or  prior to the  Effective  Time;  provided,  however,  that no Party  shall be
obligated to make annual premium  payments for such insurance to the extent such
premiums  exceed 150% of the annual  premiums  paid by such Party as of the date
hereof for such insurance  (such 150% amount,  the "Maximum  Premium").  If such
insurance  coverage  cannot be  obtained  at all,  or can only be obtained at an
annual premium in excess of the Maximum  Premium,  such Party shall maintain the
most advantageous  policies of directors' and officers' insurance obtainable for
an annual premium equal to the Maximum Premium.

                  Section 5.12.  Further  Assurances.  The SPAR Parties shall at
any time after the Effective  Time,  upon request,  take such further action and

                CLOSING NET WORTH; NONSURVIVAL OF REPRESENTATIONS

                  Section 7.01.     SPAR Closing Net Worth.

                  (a) As soon as  practicable,  but in any event  within  thirty
(30) days following the Closing Date, PIA Delaware shall cause Ernst & Young LLP
to audit the books of SAI and its  subsidiaries  to determine the SPAR Net Worth
(as  hereinafter  defined)  immediately  prior to the Merger (the  "Closing  Net
Worth").  "SPAR Net Worth" shall mean the  consolidated net worth of SAI and its
subsidiaries,  calculated  in  accordance  with  generally  accepted  accounting
principles ("GAAP") consistently  applied,  excluding (i.e., without taking into
account) (i) up to $300,000 of non-capitalizable  merger transaction charges and
other one time expenses, reserves or accruals related to the SPAR Reorganization
Transactions  or the Merger,  and (ii) any tax accruals and similar  adjustments
necessitated by the SPAR Premerger Transactions.

                  (b) Promptly after such  calculation of the Closing Net Worth,
the Surviving Corporation shall deliver to the SPAR Principals written notice of
the  Closing  Net Worth as so  calculated  (the  "Closing  Net  Worth  Notice").
Following  the  delivery of the Closing Net Worth  Notice,  the SPAR  Principals
shall have the right to review the  calculation  thereof  for a period of thirty
(30) days  after  the  delivery  of the  Closing  Net  Worth  Notice to the SPAR
Principals  (the "Review  Period").  If, the SPAR  Principals do not provide PIA
Delaware  with  written  objection to the  calculation  of the Closing Net Worth
prior to the expiration of the Review  Period,  then, (i) to the extent that the
Closing Net Worth, as set forth in the Closing Net Worth Notice, is greater than
five hundred thousand dollars  ($500,000) (the "Target  Amount"),  no adjustment
will  be  made,  and the  SPAR  Principals  will  have  no  further  obligations
hereunder;  and (ii) to the extent the  Closing  Net Worth,  as set forth in the
Closing Net Worth Notice,  is less than the Target Amount,  the SPAR  Principals
shall pay to PIA  Delaware,  within five (5) business days after the last day of
the Review Period,  the amount of such shortfall,  such payment obligation to be
borne by the SPAR  Principals  pro rata  (44/72  by Mr.  Brown  and 28/72 by Mr.
Bartels),  and to be satisfied  either (at the election of the SPAR  Principals)
(A) by wire  transfer  of  immediately  available  funds to such  account as PIA
Delaware may designate or (B) by  corresponding  reductions in the loans owed to
the SPAR Principals from SMCI.

                  (c) If the SPAR  Principals  provide PIA Delaware with written
objection  (which  objection  shall  specify  the  basis for such  objection  in
reasonable  detail) to the  calculation  of the  Closing  Net Worth prior to the
expiration  of the Review  Period,  PIA Delaware and the SPAR  Principals  shall
attempt to resolve such dispute through good faith  negotiations for a period of
at least  thirty (30) days (or such longer  period as PIA  Delaware and the SPAR
Principals may agree).  If PIA Delaware and the SPAR  Principals  cannot resolve
such  dispute  in such  period,  then  such  dispute  shall  be  resolved  by an
independent nationally recognized accounting firm which is reasonably acceptable
to PIA Delaware and the SPAR Principals (the "Independent Accounting Firm"). The
Independent Accounting Firm shall make its determination of the Closing Date Net
Worth within thirty (30) days of its selection.  The  determination  made by the
Independent  Accounting  Firm shall be final and binding on the parties  hereto.
The costs of the Independent Accounting Firm shall be borne by PIA Delaware.

                                  ARTICLE VIII

                            TERMINATION OF AGREEMENT

                  Section 8.01.    Termination. This Agreement may be terminated

pending transactions described in the SPAR Disclosure Letter, this Agreement and
the SPAR  Premerger  Agreements,  or (iii) any adverse  change(s) in the overall

SPAR Party fails to comply after notice with any of its  covenants or agreements
contained  herein,  which breaches or failures,  as the case may be, are, in the
aggregate,  material in the  context of the  transactions  contemplated  by this
Agreement and cannot  reasonably be  anticipated  to be cured within thirty (30)
days of the date of such notice;

                  (c) by SAI, on forty eight (48) hours'  written  notice to PIA
Delaware,  if there is a breach of any of the  representations and warranties of
any PIA Party (other than as a result of (i) the conduct of their  businesses as

notice with any of its covenants or agreements  contained herein, which breaches
or failures, as the case may be, are, in the aggregate,  material in the context
of the  transactions  contemplated  by this  Agreement and cannot  reasonably be
anticipated to be cured within thirty (30) days of the date of such notice;

                  (d) by PIA  Delaware  on  written  notice  to  SAI,  if (i) an
Acquisition  Proposal  has  been  made and not  withdrawn,  (ii) a  majority  of
disinterested  members of the PIA Delaware Board  determines in good faith (with
the  advice of  independent  financial  advisors  and legal  counsel)  that such
Acquisition  Proposal  is  superior  for  PIA  Delaware's  stockholders  to  the
transaction contemplated by this Agreement,  (iii) PIA Delaware has notified SAI
in writing of the  determination  described in clause (ii) above,  (iv) at least
five (5)  business  days have elapsed  following  receipt by SAI of such written
notice and (taking into account any revised  proposal  made by SAI since receipt

Proposal and a majority of the disinterested directors of the PIA Delaware Board
has again made the  determination  referred to in clause (ii) above, (v) the PIA
Delaware Board concurrently approves, and (vii) PIA Delaware concurrently enters

                  (e) by either PIA  Delaware or SAI,  on written  notice to the
other, if the Merger shall not have been consummated on or before June 30, 1999;
provided,  however,  that (i) PIA  Delaware  may not  terminate  this  Agreement
pursuant  to this  clause (e) if such  failure to  consummate  the Merger is the
result of a failure to satisfy any of the  conditions  to the  obligation of the
SPAR Parties to effect the Merger set forth in Section 6.02 and (ii) SAI may not
terminate  this  Agreement  pursuant  to  this  clause  (e) if such  failure  to
consummate  the  Merger  is  the  result  of a  failure  to  satisfy  any of the
conditions  to PIA  Delaware's  obligation  to effect  the  Merger  set forth in
Section 6.03;

                  (f) by either PIA  Delaware or SAI,  on written  notice to the
other,  if a  Governmental  Entity  shall  have  enacted,  issued,  promulgated,
enforced,  or entered  any law,  rule,  regulation,  injunction  or other  order
(whether  temporary,  preliminary  or  permanent)  that is in effect and has the
effect of making  illegal  or  otherwise  prohibiting  the  consummation  of the
transactions contemplated by this Agreement; and

                  (g) by  SAI  or PIA  Delaware,  if  upon  a  vote  at the  PIA

8.01,  no Party  hereto (or any of its  directors  or  officers)  shall have any
liability or further  obligation  to any other Party to this  Agreement.  In the
event of any  termination  of this  Agreement  pursuant to clauses (b) or (c) of
Section 8.01, such termination  shall not limit or affect in any way the ability
of the non-breaching  Parties to seek damages from the breaching Parties for any
breach of this Agreement.

                  Section 8.03.  Breakup Fee. In the event of any termination of

breakup fee equal to the product of (i) 0.035 times (ii) the Value Per Share (as
defined below) times the number of shares of PIA Delaware Stock then outstanding
(without  giving effect to any shares of PIA Delaware Stock to be issued in such
transaction),  and (b) the amount of the  reasonable  costs and  expenses of the
SPAR  Parties  and  the  SPAR   Principals   incurred  in  connection  with  the
preparation,  negotiation,  execution and  performance of this Agreement and all
related  instruments  and documents  and all  securities,  anti-trust  and other
governmental  filings,  including  (without  limitation)  the  reasonable  fees,
disbursements  and expenses of attorneys,  accountants and other  professionals,
subject to receipt of  appropriate  invoices and other  documentation  therefor.
"Value  Per  Share"  shall  mean (A) the cash  purchase  price  per share of PIA
Delaware Stock where all or a majority of the outstanding shares of PIA Delaware
Stock are to be purchased for cash, or (B) in all other cases, the value of each
share of PIA Delaware  Stock,  as valued in good faith by the Board of Directors
of PIA Delaware (based on the fairness  opinion or other valuation  furnished to
them by the investment  bankers or others providing  comfort to the PIA Delaware
Board in connection with the alternative Acquisition Proposal), but in any event
not less than the average of the last sale price for PIA  Delaware  Stock on the
Nasdaq Stock Market for the five trading days  preceding the  effective  date of
the termination of this Agreement.

                                   ARTICLE IX

                  Section 9.01. Successors and Assigns; Assignment.  Whenever in
this  Agreement or any other Merger  Document  reference is made to any Party or
other person, such reference shall be deemed to include the successors, assigns,
heirs and legal  representatives  of such  person,  and,  without  limiting  the
generality  of the  foregoing,  this  Agreement  shall be binding upon and shall
inure to the benefit of the parties hereto and their  respective  successors and
assigns;  provided  that the  rights of a Party  hereunder  may not be  assigned
without the consent of the other parties hereto.

                  Section  9.02.  No Third Party  Rights.  The  representations,

Documents are for the exclusive  benefit of the Parties  hereto,  and, except as
otherwise  expressly  provided  herein or therein,  no other  person,  including
creditors of any Party  hereto,  shall have any right or claim against any Party
by reason of any of those terms and  provisions or be entitled to enforce any of
those terms and provisions against any Party.

                  Section 9.03. Counterparts.  This Agreement may be executed in
two or more  counterpart  copies of the entire document or of signature pages to
the  document,  each of  which  may be  executed  by one or more of the  parties

agreement binding upon all of the parties hereto.

delivered by hand or by nationally recognized courier service, when delivered at
the  address  specified  in this  Section  (or in  accordance  with  the  latest
unrevoked  written  direction  from such Party) and (ii) if given by telecopier,
when such telecopy is  transmitted to the  telecopier  number  specified in this
Section (or in accordance with the latest unrevoked  written direction from such
Party), and the appropriate confirmation is received.

                  Section 9.06.  Governing Law. This Agreement shall be governed
by and construed in accordance  with the Applicable Laws pertaining in the State
of New York (other than those laws that would defer to the  substantive  laws of
another jurisdiction);  provided,  however, that the approval by the Constituent
Corporations,  the Articles of Merger and filing, the effects of the Merger, and
other  corporate   organization  and  governance   matters   pertaining  to  the
Constituent  Corporations  shall be governed by and construed in accordance with
the  Applicable  Laws  pertaining  in the State of  Nevada.  Without  in any way
limiting the preceding choice of law, the parties intend (among other things) to
thereby  avail  themselves  of the  benefit  of  Section  5-1401 of the  General
Obligations Law of the State of New York.

                  Section 9.07.  Consent to Jurisdiction,  Etc. The Parties each
hereby consent and agree that the Supreme Court of the State of New York for the
County of  Westchester  and the United  States  District  Court for  Westchester
County,  New York, and the Superior  Court of the County of Orange,  California,
and the United States  District  Court for the Central  District of  California,
each shall have  personal  jurisdiction  and  proper  venue with  respect to any
dispute  between the Parties;  provided  that the  foregoing  consent  shall not
deprive any Party of the right to  voluntarily  commence or  participate  in any
action, suit or proceeding in any other court having jurisdiction and venue over
the other  Parties.  In any dispute with the SPAR Parties,  the PIA Parties will
not raise,  and each hereby  expressly  waives,  any objection or defense to any
such New York jurisdiction as an inconvenient forum. Without in any way limiting
the preceding  consents to  jurisdiction  and venue,  the parties  intend (among
other  things) to thereby avail  themselves of the benefit of Section  5-1402 of
the General Obligations Law of the State of New York.

                  Section 9.08.    Waiver of Jury Trial. In any action,  suit or
proceeding in any jurisdiction, the Parties each hereby expressly waive trial by
jury.

                  Section  9.09.  Exercise  of Rights  and  Remedies.  Except as
otherwise provided herein, no delay of or omission in the exercise of any right,
power or remedy  accruing  to any Party as a result of any  breach or default by
any other  Party under this  Agreement  shall  impair any such  right,  power or
remedy,  nor shall it be  construed as a waiver of or  acquiescence  in any such
breach or  default,  or of any similar  breach or default  occurring  later.  No
waiver of any  single  breach or  default  shall be deemed a waiver of any other
breach or default occurring before or after such waiver.

                  Section  9.10.  Reformation  and  Severability.  In  case  any
provision  of this  Agreement  shall be invalid,  illegal or  unenforceable,  it
shall, to the extent possible,  be modified in such manner as to be valid, legal
and enforceable  but so as to most nearly retain the intent of the parties,  and
if such modification is not possible,  such provision shall be severed from this
Agreement, and in either case, the validity,  legality and enforceability of the
remaining  provisions  of this  Agreement  shall not in any way be  affected  or
impaired thereby.

                  Section  9.11.  Remedies  Cumulative.   No  right,  remedy  or
election given by any term of this Agreement shall be deemed exclusive, but each
shall be cumulative with all other rights,  remedies and elections  available at
law or in equity.

                  Section 9.12.    Captions.  The headings of this Agreement are
inserted for convenience  only and shall not constitute a part of this Agreement
or be used to construe or interpret any provision hereof.

                  Section 9.13.    Amendments. This Agreement may be modified or
amended  only by a written  instrument  executed by the SPAR Parties and the PIA
Parties.

supersede  any prior  agreements  and  understandings,  relating  to the subject

replaced  from  time  to  time  in the  manner  provided  therein,  the  "Merger
Agreement"). Capitalized terms used and not otherwise defined or amended in this
Amendment  shall have the meanings  respectively  assigned to them in the Merger
Agreement or other "Merger Documents" (as defined in the Merger Agreement).

                  The  Parties  have  each  determined  that  it is in its  best
interest to amend the  Existing  Merger  Agreement as provided  below,  and have
entered into this Amendment in order to do so, all upon the terms and provisions
and subject to the conditions hereinafter set forth.

                                    Agreement

                  In  consideration  of the foregoing,  the mutual covenants and
agreements  hereinafter set forth and other good and valuable consideration (the
receipt  and  adequacy of which are hereby  acknowledged  by the  Parties),  the
Parties hereto hereby agree as follows:

                  Section 1.  Amendment to Existing Merger Agreement. The
Existing Merger Agreement is hereby amended as follows, effective as of the date
first written above:

                  (A)  Recital  E of the  Existing  Merger  Agreement  is hereby
deleted in its entirety,  and the following new Recital E is hereby  inserted in
its place:

                  E.  Pursuant to the SPAR  Reorganization  Agreement,  SAI will
         issue to the SPAR Principals  sufficient additional shares of SAI Stock
         such that (after such issuance and including shares  previously  issued
         to them)  they  will then  together  own  shares of SAI Stock  equal in
         number to (i) the  product of (A) two and  one-third  (2 1/3) times (B)
         the  total  number  of shares  of PIA  Delaware  Stock (as  hereinafter
         defined)  issued and  outstanding  as of the close of  business  on the
         Business   Day   preceding   the  Closing   Date  (as  defined  in  the
         Reorganization  Agreement),  minus (ii) the sum of the number of shares
         of SAI Stock


                                       -1-

<PAGE>

         issuable  upon  exercise  of the SAI  Options  (without  regard  to the
         vesting  provisions   thereof)  plus  shares  of  SAI  Stock  owned  by
         stockholders other than the SPAR Principals.

                  (B)  Recital  I of the  Existing  Merger  Agreement  is hereby
deleted in its entirety,  and the following new Recital I is hereby  inserted in
its place:

                  I. As provided  herein,  (i) as a result of the  Merger,  each
         outstanding  share of SAI Common Stock will be converted into the right
         to receive one share of common stock of PIA  Delaware,  par value $0.01
         per share ("PIA Delaware Stock"),  and (ii) following the Merger,  each
         SAI Option  Holder will  receive a  Substitute  Option (as  hereinafter
         defined) to purchase the same number of shares of PIA Delaware Stock on
         the same  terms as the  number of  shares  of SAI  Stock  that such SAI
         Option  Holder  was  entitled  to  purchase   under  such  SAI  Option.
         Immediately  following the Merger,  (A) the SPAR Stockholders will hold
         and the SAI Option Holders will have the right to acquire upon exercise
         (without  regard to vesting)  shares of PIA Delaware Stock that, in the
         aggregate, will represent approximately 70% of the sum of (1) the total
         number  of  shares  of  PIA  Delaware  Stock  issued  and   outstanding
         immediately after the Merger plus (2) the total number of shares of PIA
         Delaware  Stock  issuable  upon  exercise  of  the  Substitute  Options
         (without  regard to vesting),  and (B) the shares of PIA Delaware Stock
         held by  stockholders of PIA Delaware  immediately  prior to the Merger
         will represent approximately 30% of such post-Merger sum.

                  (C)  In  Section  4.03  of  the  Existing  Merger   Agreement,
subsection  (b) is  hereby  deleted  in its  entirety,  and  the  following  new
subsection (b) is hereby inserted in its place:

                  (b) The Board of Directors of PIA Delaware  (the "PIA Delaware
         Board") (i) has authorized and approved the adoption of an amendment to
         PIA Delaware's  certificate of incorporation in the form annexed hereto
         as Exhibit E  (together  with such  changes  as may be made  therein in
         accordance with the PIA Delaware Board's  approval,  but subject to the
         consent of the SPAR  Parties,  the "Charter  Amendment"),  which (among
         other  things)  provides  for an increase in the  authorized  number of
         shares of PIA Delaware Stock to 47,000,000 shares,  changes the name of
         PIA Delaware to "SPAR  Group,  Inc." (or such other name as the Parties
         may  mutually  agree prior to the mailing of the PIA Proxy  Materials),
         and deletes Article Tenth containing the prohibition against actions by
         stockholders  without a meeting (i.e., Charter Amendment No. 1, Charter
         Amendment  No. 2, Charter  Amendment  No. 3 as defined in the PIA Proxy
         Statement); (ii) has authorized for inclusion in the proxy statement, a
         proposal to authorize the PIA Delaware  Board,  if deemed  necessary in
         its sole discretion  (after  obtaining the consent of the SPAR Parties,
         if  such  amendment  is to be  effected  prior  to  the  Merger  or the
         termination of this Agreement),  to amend PIA Delaware's certificate of
         incorporation  (in the form annexed  hereto as Exhibit E-1) to effect a
         reverse  stock  split  of the  issued  and  outstanding  shares  of PIA
         Delaware  Stock on the basis of one of the  following  ratios:  one new
         share in exchange for every two issued and outstanding  shares, one new
         share in exchange for every three issued and outstanding shares, or one
         new share in  exchange  for every four issued and  outstanding  shares,
         with the PIA Delaware  Board  having the  discretion  to determine  the
         appropriate  ratio to use  immediately  prior to effecting  the reverse
         stock split (the "Reverse Split Proposal" and together with the Charter
         Amendment, the "Proposed PIA Certificate of Amendment"),  and (iii) has
         directed that the Proposed PIA Certificate of Amendment be submitted to
         PIA Delaware's  stockholders at the PIA  Stockholders  Meeting (as such
         term is defined in Section 5.01). Upon the approval of the Proposed PIA
         Certificate  of  Amendment  by  the  stockholders  of PIA  Delaware  as
         required by the Delaware  General  Corporation Law (the "DGCL") and the
         filing  thereof  with the  Secretary of State of the State of Delaware,
         the shares of PIA Delaware  Stock to be issued in  connection  with the
         Merger will be duly authorized and, when issued as contemplated  hereby
         at and after the Effective Time, will be validly issued, fully paid and
         nonassessable and free of all Restrictions.

                  (D)  In  Section  7.01  of  the  Existing  Merger   Agreement,
subsection  (b) is  hereby  deleted  in its  entirety,  and  the  following  new
subsection (b) is hereby inserted in its place:

                  (b) Promptly after such  calculation of the Closing Net Worth,
         the Surviving  Corporation shall deliver to the SPAR Principals written
         notice of the  Closing Net Worth as so  calculated  (the  "Closing  Net
         Worth Notice"). Following the delivery of the Closing Net Worth Notice,
         the SPAR  Principals  shall  have the right to review  the  calculation
         thereof  for a period of thirty  (30) days  after the  delivery  of the
         Closing Net Worth Notice to the SPAR Principals (the "Review  Period").
         If, the SPAR  Principals  do not  provide  PIA  Delaware  with  written
         objection  to the  calculation  of the  Closing  Net Worth prior to the
         expiration  of the Review  Period,  then,  (i) to the  extent  that the
         Closing Net Worth, as set forth in the Closing Net Worth

                                       -2-
<PAGE>



         Notice,  is greater than one million four hundred  thirty-six  thousand
         dollars ($1,436,000) (the "Target Amount"), no adjustment will be made,
         and the SPAR Principals will have no further obligations hereunder; and
         (ii) to the extent the Closing  Net Worth,  as set forth in the Closing
         Net Worth Notice,  is less than the Target Amount,  the SPAR Principals
         shall pay to PIA Delaware, within five (5) business days after the last
         day of the Review Period,  the amount of such  shortfall,  such payment
         obligation  to be borne by the SPAR  Principals  pro rata (44/72 by Mr.
         Brown and 28/72 by Mr.  Bartels),  and to be  satisfied  either (at the
         election of the SPAR  Principals)  (A) by wire transfer of  immediately
         available funds to such account as PIA Delaware may designate or (B) by
         corresponding  reductions in the loans owed to the SPAR Principals from
         SMCI.

                  (E) Exhibit E-1 to the  Existing  Merger  Agreement  is hereby
inserted in the form annexed hereto as Exhibit 1.

                  (F) Each of the Parties hereto hereby acknowledges and, to the
extent such Party's consent may be required under the Merger Agreement, consents
to the First Amendment to Reorganization Agreement, dated as of the date hereof,
a copy of which is annexed hereto as Exhibit 2.

                  Section 2.  Counterparts.  This Amendment may be signed in two
or more  counterpart  copies of the entire document or of signature pages to the
document,  each of which may be executed  by one or more of the Parties  hereto,
but all of which,  when taken  together,  shall  constitute  a single  agreement
binding upon all of the Parties hereto.

                  Section 3.  Governing  Law,  Etc.  This  Amendment is a Merger
Document  and  shall  be  governed  by and  construed  in  accordance  with  the
applicable  terms  and  provisions  of  Article  IX (as  well as any  applicable
definitions  or provisions  appearing  elsewhere) of the Merger  Agreement as if
this  Amendment  were  the  Agreement  referred  to  therein,  which  terms  and
provisions are incorporated herein by reference.

                  Section  4.  Agreement  to  Continue  as  Amended.  The Merger
Agreement, as supplemented, modified and amended by this Amendment, shall remain
and continue in full force and effect after the date hereof.

                  Section 5.  Entire  Agreement.  This  Amendment  contains  the
entire  agreement  of the  Parties  and  supersedes  all other  representations,
warranties, agreements and understandings,  oral or otherwise, among the parties
with respect to the matters contained herein.

                  In Witness  Whereof,  the  Parties  hereto have  executed  and

  FORM OF REVERSE SPLIT AMENDMENT TO PIA DELAWARE CERTIFICATE OF INCORPORATION


               Upon this Certificate of Amendment to the Certificate
     of Incorporation of the Corporation becoming effective pursuant
     to the General  Corporation  Law of the State of Delaware  (the
     "Effective  Time"),  each  share  of the  Corporation's  common
     stock,  par value  $.01 per share  (the  "Old  Common  Stock"),
     issued and outstanding immediately prior to the Effective Time,
     will  be  automatically  reclassified  as  and  converted  into
     [_________]  of a share of common  stock,  par  value  $.01 per
     share, of the Corporation  (the "New Common Stock").  Any stock
     certificate  that,  immediately  prior to the  Effective  Time,
     represented shares of the Old Common Stock will, from and after
     the Effective Time,  automatically and without the necessity of
     presenting  the same for  exchange,  represent  the  number  of
     shares of the New Common  Stock as equals the product  obtained
     by  multiplying  the  number  of  shares  of Old  Common  Stock
     represented  by  such  certificate  immediately  prior  to  the
     Effective  Time by  [________].  No  fractional  shares  of New
     Common   Stock   will  be   issued  in   connection   with  the
     reclassification  and  conversion  of the Old Common Stock into
     the New Common Stock.  In lieu of any fractional  shares,  each

SPAR Principal and delivered to the Indemnity Escrow Agent, provided however
that the Share Escrow Amount may be satisfied by the shares of the SPAR
Principals as opposed to the shares of such Family Members; and (ii) each SPAR

                  (c) Capitalized terms used and not otherwise defined herein
shall have the meanings respectively assigned to them in the Merger Agreement or

thereof into this Agreement unless expressly so provided.

                  Section 2. Investment of Funds. The Indemnity Escrow Agent may

         SPAR Principals under the Limited Indemnity Agreement have been
         satisfied in full;

(b)      the Indemnity Escrow Agent shall release all of the then remaining
         Escrow Shares and other property in the Escrow Deposit to the SPAR

         of written notice (a "Release Notice") from any SPAR Principal
         certifying that the obligations of the SPAR Principals under the
         Limited Indemnity Agreement have been satisfied in full and certifying
         that PIA Delaware has concurrently been given a copy of such Release
         Notice; provided, however, that the Escrow Deposit shall not be so
         released if PIA Delaware delivers written objection to such release to
         the Indemnity Escrow Agent prior to the close of business on the tenth
         Business Day after the Indemnity Escrow Agent's receipt of such Release
         Notice, in which event the Parties shall resolve such dispute in the

         the eleventh Business Day following receipt by the Indemnity Escrow
         Agent of such written request from PIA Delaware, acting in its own name
         or as agent for any other Beneficiary (an "Indemnity Claim Notice"),
         which notice shall (i) concurrently be delivered to the SPAR Principals
         and the Indemnity Escrow Agent (and shall include a certification to
         such effect), (ii) state that the Escrow Shares and other property

         contain such facts and information as are then reasonably available
         concerning the basis for the claim for indemnification; provided,
         however, that the Indemnity Escrow Agent shall not release such Escrow
         Shares or other property as requested if one or both of the SPAR
         Principals has delivered written objection to such release to the
         Indemnity Escrow Agent prior to the close of business on the tenth
         Business Day following the receipt of such Indemnity Claim Notice, in
         which event the Parties shall resolve such dispute in the manner
         provided in Section 7 hereof;

         2000, the Indemnity Escrow Agent has not received an Indemnity Claim
         Notice under Article III of the Limited Indemnification Agreement that
         then to its knowledge remains unsatisfied or in dispute (which the
         Indemnity Escrow Agent may in its discretion confirm through notices to
         the Beneficiaries); provided, however, that the Escrow Deposit shall


                                       -2-
<PAGE>

         not be so released if PIA Delaware delivers written objection to such
         release and an Indemnity Claim Notice under Article III of the Limited
         Indemnification Agreement to the Indemnity Escrow Agent prior to the
         close of business on March 29, 2000, in which event the Parties shall
         resolve such dispute in the manner provided in Section 7 hereof;

(e)      the Board of Directors of PIA Delaware shall in their board meetings
         preceding the second, third and fourth anniversaries of the date of
         this Agreement evaluate the amount of collateral reasonably necessary
         to continue to secure the SPAR Principals' obligations under the
         Limited Indemnification Agreement (the "Continuing Amount"), not to
         exceed $1,500,000, and give written notice to the Indemnity Escrow
         Agent of the Continuing Amount; and the Indemnity Escrow Agent shall
         retain Escrow Shares having a Fair Market Value (as hereinafter
         defined) equal to the Continuing Amount and release all the then
         remaining Escrow Shares and other property in the Escrow Deposit in
         excess of the Continuing Amount to the SPAR Principals, in accordance
         with their respective interests therein, if the Indemnity Escrow Agent
         has received that notice and the Indemnity Escrow Agent has not
         received an Indemnity Claim Notice under Article II of the Limited
         Indemnification Agreement that then to its knowledge remains
         unsatisfied or in dispute (which the Indemnity Escrow Agent may in its
         discretion confirm through notices to the Beneficiaries); provided,
         however, that the Escrow Deposit shall not be so released if PIA
         Delaware delivers written objection to such release and an Indemnity
         Claim Notice under Article II of the Limited Indemnification Agreement
         to the Indemnity Escrow Agent prior to the close of business on the
         tenth Business Day prior to the applicable anniversary of the date
         hereof, in which event the Parties shall resolve such dispute in the
         manner provided in Section 7 hereof; and

(f)      the Indemnity Escrow Agent shall release all of the then remaining
         Escrow Shares and other property in the Escrow Deposit to the SPAR
         Principals, in accordance with their respective interests therein, if
         by the close of business on the eleventh Business Day following the
         fifth anniversary of the date of this Agreement the Indemnity Escrow
         Agent has not received an Indemnity Claim Notice under Article II of
         the Limited Indemnification Agreement that then to its knowledge
         remains unsatisfied or in dispute (which the Indemnity Escrow Agent may
         in its discretion confirm through notices to the Beneficiaries);
         provided, however, that the Escrow Deposit shall not be so released if
         PIA Delaware delivers written objection to such release and an
         Indemnity Claim Notice under Article II of the Limited Indemnification
         Agreement to the Indemnity Escrow Agent prior to the close of business
         on the tenth Business Day after the fifth anniversary of the date of
         this Agreement, in which event the Parties shall resolve such dispute
         in the manner provided in Section 7 hereof.

In determining the number of Escrow Shares to be transferred in satisfaction of
any claim against the Escrow Property pursuant to the foregoing clause (c) or
retained in escrow (if any) under the foregoing clause (e), each Escrow Share
shall be valued at the average last sale price on the Nasdaq National Market for
the PIA Delaware Stock for the twenty (20) trading days ending two trading days
prior to the date on which such shares are to be transferred or released (the
"Fair Market Value"). PIA Delaware shall notify the Indemnity Escrow Agent in
writing of the appropriate valuation for the Escrow Shares for such purposes.
Each of the SPAR Principals and other Beneficiaries hereby expressly authorizes
and instructs the Indemnity Escrow Agent to take any and all action required to
effect any transfer of Escrow Shares and/or other property pursuant to the terms
of this Agreement, including, without limitation, completing and delivering one
or more of the executed stock powers delivered to the Indemnity Escrow Agent
pursuant to Section 1.

                  Section 4. Substitution of Cash for Escrow Shares. The SPAR
Principals shall have the right at any time and from time to time to substitute
cash for Escrow Shares as follows: (i) the SPAR Principals shall give written
notice to the Indemnity Escrow Agent and the Merger Parties at least ten days
prior to any requested substitution; (ii) on or before the proposed substitution
date, the SPAR Principals shall deliver $5.00 per share in immediately available
funds to the Indemnity Escrow Agent for each share of PIA Delaware Stock to be
released in substitution, provided, however, that to the extent the amount of
the Escrow Shares has been reduced pursuant to Section 3(e) hereof, the per
share substitution price for the each share of PIA Delaware Stock in the
Continuing Amount shall instead be the Fair Market Value as of the business day
immediately preceding the day such written notice is sent; and (iii) upon
receipt of such funds by the Indemnity Escrow Agent, the Indemnity Escrow Agent
shall release the corresponding shares of PIA Delaware Stock to the SPAR
Principals, in accordance with their respective interests therein, whether or
not any Indemnity Claim Notice has been received by the Indemnity Escrow Agent.

                  Section 5. Further Assurances. Each Beneficiary agrees to do
such further acts and things and to execute and deliver such statements,
assignments, agreements, instruments and other documents as the Indemnity Escrow
Agent from time to time reasonably may request in order to effectuate the
purpose and the terms and provisions of this Agreement, each in such form and
substance as may be acceptable to the Indemnity Escrow Agent.

                  Section 6. Invalidation of Distributions, Etc. In the event
any amount or document released to any Beneficiary under this Agreement is
invalidated, declared to be fraudulent or preferential or must otherwise be
restored or returned by the Indemnity Escrow Agent in connection with the
insolvency, bankruptcy or reorganization of any Beneficiary or other person,
whether by order of or settlement before any court or other authority or
otherwise: (a) each Beneficiary shall contribute back to the Indemnity Escrow
Agent an amount received by it such that each Beneficiary will be affected by
that invalidation, declaration, restoration or return ratably in proportion to
the distributions it received under this Agreement; and (b) each Beneficiary
will return any document so affected, together with any related assignment,
release or other instrument or document the Indemnity Escrow Agent may request
to restore the status quo ante.

                  Section 7.        Conflicting Demands.

                  (a) In the event that one or both of the SPAR Principals or
PIA Delaware timely objects to any requested release of or claim against any of
the Escrow Shares or other property pursuant to Section 3, then PIA Delaware and
the SPAR Principals shall, for a period of at least thirty days, negotiate in
good faith in an effort to resolve such dispute. If PIA Delaware and the SPAR
Principals are unable to resolve such dispute within such thirty day period (or
such longer period as they may mutually agree upon), then the Beneficiaries may
pursue non-binding mediation if they mutually agree, or any Beneficiary may
commence an action, to finally resolve any conflicting claims hereunder. The
final decision of any court proceeding shall be furnished in writing to the
Indemnity Escrow Agent.

                  (b) If conflicting or adverse claims or demands are made or
notices served upon the Indemnity Escrow Agent with respect to the escrow
provided for herein, the Beneficiaries agree that the Indemnity Escrow Agent
shall be entitled to refuse to comply with any such claim or demand and to
withhold and stop all further performance of this escrow so long as such
disagreement shall continue. In so doing, the Indemnity Escrow Agent shall not
be or become liable for damages, losses, expenses or interest to any Beneficiary
or any other person for its failure to comply with such conflicting or adverse
demands. The Indemnity Escrow Agent shall be entitled to continue to so refrain
and refuse to so act until: (a) the rights of the adverse claimants have been
finally adjudicated in a court assuming and having jurisdiction and venue over
the parties and/or the documents, instruments or funds involved herein or
affected hereby; and/or (b) the Indemnity Escrow Agent shall have received an
executed copy of a dispositive settlement agreement to which the Beneficiaries
and all other adverse claimants, if any, are parties and signatories.

                  (c) If conflicting or adverse claims or demands are made or
notices served upon the Indemnity Escrow Agent with respect to the escrow
provided for herein, the Beneficiaries agree that the Indemnity Escrow Agent
also may elect to commence an interpleader or other action for declaratory
judgment for the purpose of having the respective rights of the claimants
adjudicated, and may deposit with the court all funds and documents held
hereunder pursuant to this Agreement; and if it so commences and deposits, the
Indemnity Escrow Agent shall be relieved and discharged from any further duties
and obligations under this Agreement. PIA Delaware shall pay all costs, expenses
and attorneys' fees and expenses incurred by the Indemnity Escrow Agent in
seeking any such judgment.

                  Section 8. Consent to Jurisdiction, Etc. Each Beneficiary
hereby covenants and agrees that the Supreme Court of the State of New York for
the County of Westchester or (in a case involving diversity of citizenship) the
United States District Court for the Southern District of New York shall have
personal jurisdiction and proper venue over any dispute with the Indemnity
Escrow Agent; provided that the foregoing consent to jurisdiction and venue by
the other parties shall not deprive the Indemnity Escrow Agent of the right in
its discretion to voluntarily commence or participate in any action, suit or
proceeding in any other court having jurisdiction and venue over the
Beneficiaries. In any dispute with the Indemnity Escrow Agent, no Beneficiary
will raise, and each Beneficiary hereby expressly waives, any objection or
defense to any such jurisdiction as an inconvenient forum. Without in any way
limiting the preceding consents to jurisdiction and venue, the parties intend
(among other things)

                                       -4-
<PAGE>

to thereby avail themselves of the benefit of Section 5-1402 of the General
Obligations Law of the State of New York. In addition to (and without limitation
of) any delivery permitted under applicable law, each Beneficiary agrees that
service of process may be made at his or its office in Westchester County, New
York.

                  Section 9. Waiver of Jury Trial.  In any action or proceeding
involving the Indemnity Escrow Agent in any jurisdiction, the Parties each waive
trial by jury.

                  Section 10. Expenses of the Indemnity Escrow Agent. PIA
Delaware shall pay any and all costs and expenses incurred by the Indemnity
Escrow Agent in connection with the administration and holding of the Escrow
Deposit and the investment of any Escrow Funds, and the enforcement, protection
and adjudication of the parties' rights hereunder by the Indemnity Escrow Agent,
including, without limitation, the disbursements, expenses and fees of the
Indemnity Escrow Agent itself and those of other attorneys it may retain, if
any.

                  Section 11. Reliance on Documents and Experts. The Indemnity
Escrow Agent shall be entitled to rely upon any notice, consent, certificate,
affidavit, statement, paper, document, writing or communication (which to the
extent permitted hereunder may be by telegram, cable, telex, telecopier, or
telephone) reasonably believed by it to be genuine and to have been signed, sent
or made by the proper person or persons, and upon opinions and advice of legal
counsel (including itself or counsel for any party hereto), independent public
accountants and other experts selected by the Indemnity Escrow Agent.

                  Section 12. Status of the Indemnity Escrow Agent, Etc. The
Indemnity Escrow Agent is acting under this Agreement as a stakeholder only and
shall be considered an independent contractor with respect to each Beneficiary.
No term or provision of this Agreement is intended to create, nor shall any such
term or provision be deemed to have created, any principal-agent, trust, joint
venture, partnership, debtor-creditor or attorney-client relationship between or
among the Indemnity Escrow Agent and any of the Beneficiaries. This Agreement
shall not be deemed to prohibit or in any way restrict the Indemnity Escrow
Agent's representation of any Beneficiary, who may be advised by the Indemnity
Escrow Agent on any and all matters pertaining to this Agreement and the Escrow
Deposit. To the extent one or more of the Beneficiaries have been, are and/or
will be represented by the Indemnity Escrow Agent, each such Beneficiary hereby
waives any conflict of interest and irrevocably authorizes and directs the
Indemnity Escrow Agent to carry out the terms and provisions of this Agreement,
in each case without regard to any representation of any such Beneficiary, with
deference to no party and fairly as to all parties, and irrespective of the
impact upon or any conflicting communication from any such Beneficiary. The
Indemnity Escrow Agent's only duties are those expressly set forth in this
Agreement, and each Beneficiary authorizes the Indemnity Escrow Agent to perform
those duties in accordance with its usual practices in holding funds and
documents of its own or those of other escrows. The Indemnity Escrow Agent may
exercise or otherwise enforce any of its rights, powers, privileges, remedies
and interests under this Agreement and applicable law or perform any of its
duties under this Agreement by or through its directors, officers, partners,
employees, attorneys, agents or designees.

                  Section 13. Exculpation. The Indemnity Escrow Agent and its
designees, and their respective directors, officers, partners, counsel,
employees, attorneys and agents, shall not incur any liability whatsoever for
(a) the investment or disposition of funds, the holding or delivery of documents
or the taking of any other action, in each case in accordance with the terms and
provisions of this Agreement, (b) any mistake or error in judgment, (c)
compliance with any applicable law or any attachment, order or other directive
of any court or other authority (irrespective of any conflicting term or
provision of this Agreement), or (d) any other act or omission of any other
independent person engaged by the Indemnity Escrow Agent in connection with this
Agreement; and each Beneficiary hereby waives any and all claims and actions
whatsoever against the Indemnity Escrow Agent and its designees, and their
respective directors, officers, partners, employees, attorneys and agents,
arising out of or related directly or indirectly to any and all of the foregoing
acts, omissions and circumstances. Furthermore, the Indemnity Escrow Agent and
its designees, and their respective directors, officers, partners, employees,
attorneys and agents, shall not incur any liability (other than for a person's
own acts or omissions breaching a duty or contractual obligation owed to the
claimant and amounting to gross negligence or willful misconduct as finally
determined pursuant to applicable law by a governmental authority having
jurisdiction) for other acts and omissions arising out of or related directly or
indirectly to this Agreement or the Escrow Deposit; and each Beneficiary hereby
expressly waives any and all claims and actions (other than those attributable
to a person's own acts or omissions breaching a duty or contractual obligation
owed to the claimant and amounting to gross negligence or willful misconduct as
finally determined pursuant to applicable law by a governmental authority having
jurisdiction) against the Indemnity Escrow Agent and its designees, and their
respective directors, officers, partners, employees, attorneys and agents,
arising out of or related directly or indirectly to any and all of the foregoing
acts, omissions and circumstances.

                  Section 14. Indemnification. The Indemnity Escrow Agent and
its designees, and their respective directors, officers, partners, employees,
attorneys and agents, shall be indemnified, reimbursed, held harmless and, at
the request of the Indemnity Escrow Agent, defended by the Beneficiaries,
jointly and severally, from and against any and all claims, liabilities, losses
and expenses (including, without limitation, the disbursements, expenses and
fees of their respective attorneys) that may be imposed upon, incurred by, or
asserted against any of them, or any of their respective directors, officers,
partners, employees, attorneys or agents, arising out of or related directly or
indirectly to this Agreement or the Escrow Deposit, except such as are
occasioned by the indemnified person's own acts and omissions breaching a duty
or contractual obligation owed to the claimant and amounting to gross negligence
or willful misconduct as finally determined pursuant to applicable law by a
governmental authority having jurisdiction.

                  Section 15. Notice. Any notice, request, demand or other
communication permitted or required to be given hereunder shall be in writing,
shall be signed by the party giving it, shall be sent by one of the following
means to the addressee at the address set forth above (or at such other address
as shall be designated hereunder by notice to the other parties and persons
receiving copies, effective upon actual receipt) and shall be deemed

account of the sender, and shall be deemed conclusively to have been given on
the first business day following the day duly sent, provided that the giving
party also sends a copy thereof by one of the other means referenced above.
Refusal to accept delivery of any item shall be deemed to be receipt of such
item by the refusing party. Copies may be sent by regular first-class mail,
postage prepaid, to such person(s) as a party may direct from time to time by
notice to the others, but failure or delay in sending copies shall not affect
the validity of any such notice, request, demand or other communication so given
to a party.

                  Section 16. Section and Other Headings.  The section and other
headings contained in this Agreement are for reference purposes only and shall
not affect the meaning or interpretation of this Agreement.

and delivered in the State of New York; and shall be governed by and construed
in accordance with the applicable laws pertaining in the State of New York
(other than those that would defer to the substantive laws of another
jurisdiction). Without in any way limiting the preceding choice of law, the
parties intend (among other things) to thereby avail themselves of the benefit
of Section 5-1401 of the General Obligations Law of the State of New York.

                  Section 18. Severability. In the event that any term or
provision of this Agreement shall be finally determined to be superseded,
invalid, illegal or otherwise unenforceable pursuant to applicable law by a
governmental authority having jurisdiction and venue, that determination shall
not impair or otherwise affect the validity, legality or enforceability (a) by
or before that authority of the remaining terms and provisions of this
Agreement, which shall be enforced as if the unenforceable term or provision
were deleted, or (b) by or before any other authority of any of the terms and
provisions of this Agreement.

                  Section 19. Counterparts. This Agreement may be executed in

this Agreement reference is made to any party, such reference shall be deemed to
include the successors, assigns, heirs and legal representatives of such party,
and, without limiting the generality of the foregoing, all representations,
warranties, covenants and other agreements made by or on behalf of each

assigns of the Indemnity Escrow Agent; provided, however, that nothing herein
shall be deemed to authorize or permit any Beneficiary to assign any of its

specific purpose for which given and shall not be deemed, regardless of
frequency given, to be a further or continuing waiver or consent. The failure or
delay of a party at any time or times to require performance of, or to exercise
its rights with respect to, any representation, warranty, covenant or other term
or provision of this Agreement in no manner (except as otherwise expressly
provided herein) shall affect its right at a later time to enforce any such term
or provision. No notice to or demand on any Party in any case shall entitle such
party to any other or further notice or demand in the same, similar or other
circumstances. All rights, powers, privileges, remedies and interests of the
Indemnity Escrow Agent under this Agreement are cumulative and not alternatives,
and they are in addition to and shall not limit (except as otherwise expressly
provided herein) any other right, power, privilege, remedy or interest of the
Indemnity Escrow Agent under this Agreement or applicable law.

                  Section 24. Modification, Amendment, Etc. Each and every
modification and amendment of this Agreement shall be in writing and signed by
all of the parties hereto, and each and every waiver of, or consent to any
departure from, any covenant, representation, warranty or other provision of
this Agreement shall be in writing and signed by each party affected thereby.
