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").

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.

Information with respect to each Reporting Person is given solely by 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 Mr. James R.

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. Page 5 of 10 pages

CUSIP NO. 784933 10 3 PAGE 6 OF 10 PAGES ---- ----- 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. Page 6 of 10 pages

CUSIP NO. 784933 10 3 PAGE 7 OF 10 PAGES ---- ----- 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.

AGREEMENT AND PLAN OF MERGER This Agreement and Plan of Merger, 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 herein, this "Agreement"), is made by and among PIA Merchandising Services, Inc., a Delaware corporation ("PIA Delaware"), SG Acquisition, Inc., a Nevada corporation ("PIA Acquisition"), PIA Merchandising Co., Inc., a California corporation ("PIA California"), SPAR Acquisition, Inc., a Nevada corporation ("SAI"), SPAR Marketing, Inc., a Delaware corporation ("SMI"), SPAR Marketing Force, Inc., a Nevada corporation ("SMF"), SPAR Marketing, Inc., a Nevada corporation ("SMNEV"), SPAR, Inc., a Nevada corporation ("SINC"), SPAR/Burgoyne Retail Services, Inc., an Ohio corporation ("SBRS"), SPAR Incentive Marketing, Inc., a Delaware corporation ("SIM"), SPAR MCI Performance Group, Inc., a Delaware corporation ("SMCI"), and SPAR Trademarks, Inc., a Nevada corporation ("STM"). SMF, SMNEV, SINC and SBRS 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 Delaware, PIA Acquisition and PIA California are sometimes referred to herein individually as a "PIA Party" and collectively as the "PIA Parties". The PIA Parties and the SPAR Parties are sometimes referred to herein individually as a "Party" and collectively as the "Parties". 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. -1-

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: -2-

ARTICLE I THE MERGER 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. -3-

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. -4-

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. ARTICLE III REPRESENTATIONS AND WARRANTIES OF THE SPAR PARTIES Except as otherwise disclosed in that certain letter of even date herewith delivered to PIA Delaware 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 "SPAR Disclosure Letter"), each SPAR Party, jointly and severally, represents and warrants to the PIA Parties as follows: Section 3.01.

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-

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-

(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, operations, assets or properties are subject. Section 3.13. Transactions With Affiliates. Except as otherwise set forth in the SPAR Disclosure Letter: (a) no stockholder and no director, officer or employee of any SPAR Marketing Company, or any member of his or her immediate family or any other of its, his or her affiliates, owns or has a 5% or more ownership interest in any material business, corporation or other entity that is or was during the last three years a party to, or in any property which is or was during the last three years the subject of, any contract, agreement, commitment or legally binding arrangement with such SPAR Marketing Company; and (b) the SPAR Disclosure Letter includes a complete list as of the date hereof of all amounts owed by any SPAR Marketing Company to any SPAR Principal (other than salary and expense reimbursements in the normal course) or any affiliate of any SPAR Principal (other than for goods purchased or services rendered in the normal course) or owed on account of any loan or advance to any SPAR Marketing Company by any SPAR Principal or any affiliate of any SPAR Principal (other than for goods purchased or services rendered in the normal course). Section 3.14. Litigation. Except as otherwise set forth in the SPAR Disclosure Letter, as of the date hereof: (a) no litigation, including any arbitration, investigation or other proceeding of or before any Governmental Entity, is pending (or to the knowledge of the SPAR Marketing Companies) overtly threatened against any SPAR Marketing Company, other than litigation that (i) is not reasonably likely to be adversely determined or (ii) if reasonably likely to be adversely determined, would not be reasonably likely to have, individually or in the aggregate with other such litigation, a SPAR Material Adverse Effect; and (b) no SPAR Marketing Company is a party to or subject to the provisions of any SPAR Court Order. Section 3.15. Taxes. Except as otherwise set forth in the SPAR Disclosure Letter: -12-

(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-

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.

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.

(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-

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-

Internal Revenue Service to be so exempt and no event or condition exists or has occurred which would adversely affect any such determination. No PIA Company has any Benefit Plan outside of the United States. (j) No PIA Company has any Benefit Plan outside of the United States. (k) All persons classified by any PIA Company as independent contractors or leased employees within the meaning of Section 414(n) of the Code ("PIA Leased Employees") satisfy and have at all times satisfied the requirements of applicable law to be so classified. Each PIA Company has fully and accurately reported their compensation on IRS Forms 1099 when required to do so. No PIA Company has any obligation to provide benefits with respect to such independent contractors or PIA Leased Employees under any PIA Benefit Plan or otherwise. Section 4.12. Compliance with Law.

Section 4.14. Litigation. Except as otherwise disclosed in the PIA Disclosure Letter: (a) no litigation, including any arbitration, investigation or other proceeding of or before any Governmental Entity is pending (or to the knowledge of the PIA Parties) overtly threatened against any PIA Company, other than litigation that (i) is not reasonably likely to be adversely determined or (ii) if reasonably likely to be adversely determined, would not be reasonably likely to have, individually or in the aggregate with other such litigation, a PIA Material Adverse Effect; and (b) no PIA Company is a party to or subject to the provisions of any PIA Court Order.

(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. -33-

This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time: (a) by the mutual written agreement of PIA Delaware and SAI; (b) by PIA Delaware, on forty eight (48) hours' written notice to SAI, if there is a breach of any of the representations and warranties of any SPAR Party (other than as a result of (i) the conduct of their businesses as permitted and required hereunder, (ii) the culmination of any proposed or pending transactions described in the SPAR Disclosure Letter, this Agreement and the SPAR Premerger Agreements, or (iii) any adverse change(s) in the overall economy or in the market segments in which such parties do business), or if any 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 permitted and required hereunder, (ii) the culmination of any proposed or pending transactions described in the PIA Disclosure Letter and this Agreement, or (iii) any adverse change(s) in the overall economy or in the market segments in which such parties do business), or if any PIA 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; (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 of such written notice) such Acquisition Proposal remains an Acquisition 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 into a definitive agreement providing for the implementation of such Acquisition Proposal, subject to the payment by the PIA Parties of the breakup fee and expense reimbursement as provided below in Section 8.03; (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 Stockholders Meeting, PIA Delaware's stockholders do not approve, (i) the Share Issuance as required under the Nasdaq Rules or (ii) the Proposed PIA Certificate of Amendment as required under the DGCL. -34-

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.

"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.

                  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-

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-

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.

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 holder of Old Common Stock who would otherwise receive a fractional share of New Common Stock will be entitled to receive cash in an amount equal to the product obtained by multiplying (1) the closing sales price of the Corporation's Common Stock at the Effective Time as reported on the Nasdaq National Market (or, if applicable, the Nasdaq SmallCap Market or any exchange that the PIA Common Stock may be traded on at the Effective Time) by (2) the number of shares of Old Common Stock held by such holder that would otherwise have been exchanged for such fractional share interest. -6-

                                    AGREEMENT

                  In consideration of the foregoing and the mutual covenants and
agreements hereinafter set forth, the parties hereto hereby agree as follows:

                  Section 1. Escrow of Instruments. (a) In accordance with the
provisions of Section 2.02 of the Merger Agreement, (i) PIA Delaware shall cause
ten percent (10%) of the shares of PIA Delaware Stock that each SPAR Principal
and their Family Members (as defined in the Merger Agreement) would otherwise
have had the right to receive pursuant to Section 2.01(a) of the Merger
Agreement (the "Escrow Shares") to be registered in the name of the applicable
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
Principal shall deposit with the Indemnity Escrow Agent four stock powers
(separate from the certificates) endorsed to PIA Delaware, all of which shall be
held in accordance with the provisions of the Limited Indemnity Agreement and
this Agreement.

(c) Capitalized terms used and not otherwise defined herein shall have the meanings respectively assigned to them in the Merger Agreement or the Limited Indemnification Agreement, as applicable. However, no reference to the Merger Agreement or the Limited Indemnification Agreement or any other instrument or document shall be deemed to incorporate any term or provision thereof into this Agreement unless expressly so provided. Section 2. Investment of Funds. The Indemnity Escrow Agent may invest or deposit any dividends or other distributions paid with respect to the Escrow Shares (the "Escrow Funds"; collectively, with the Escrow Shares, the "Escrow Deposit"), in (a) one of its normal interest bearing escrow deposit accounts with Citibank, N.A., The Chase Manhattan Bank, or their respective affiliates, (b) securities issued or guarantied by the United States of America, or (c) other interest bearing deposit accounts in, or certificates of deposit, commercial paper or similar products of, or money market mutual funds affiliated with, (i) domestic commercial banks that have, or are members of a group of domestic commercial banks that has, consolidated total assets of at least $1,000,000,000, or (ii) such other banks or other financial institutions as may be acceptable to the Beneficiaries. Section 3. Release of Funds and Documents. The Indemnity Escrow Agent shall release the Escrow Shares and other property in the escrow created hereunder as follows: (a) 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, on the second Business Day after receipt by the Indemnity Escrow Agent of written notice from PIA Delaware certifying that the obligations of the 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 Principals, in accordance with their respective interests therein, on the eleventh Business Day after receipt by the Indemnity Escrow Agent 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 manner provided in Section 7 hereof; (c) the Indemnity Escrow Agent shall release such portion of the Escrow Shares and/or other property then held in the Escrow Deposit to PIA Delaware as shall be specified by written notice from PIA Delaware, on 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 requested to be released are required to satisfy an unpaid claim for indemnification under the Limited Indemnification Agreement, (iii) set forth the dollar amount of the claim for indemnification, and (iv) 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; (d) the Indemnity Escrow Agent shall release one half of the then remaining Escrow Shares and Escrow Funds and other property attributable thereto in the Escrow Deposit to the SPAR Principals, in accordance with their respective interests therein, if by the close of business on March 31, 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-

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 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-

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. -5-

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 conclusively to have been given: (i) on the first business day following the day timely deposited with Federal Express (or other equivalent national overnight courier) or United States Express Mail for overnight delivery, with the cost of overnight delivery prepaid or for the account of the sender; (ii) on the fifth business day following the day duly sent by certified or registered United States mail, postage prepaid and return receipt requested, or (iii) when otherwise actually received by the addressee on a business day (or on the next business day if received after the close of normal business hours or on any non-business day).
