ATTACHMENT A PART III - NARRATIVE The Registrant's Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2000 could not be filed within the prescribed time period since the Registrant has not finalized all of its accounting matters in connection with the recent reverse merger of its subsidiary with SPAR Acquisition, Inc. As a result, the financial statements of the Registrant for the fiscal quarter ended March 31, 2000 and the notes thereto, have not yet been completed.

ATTACHMENT B PART IV - OTHER INFORMATION The Registrant anticipates reporting that the results of operations for the fiscal quarter ended March 31, 2000 have substantially changed in comparison with the results of operations for the fiscal quarter ended March 31, 1999. The reverse merger between a subsidiary of SPAR Group, Inc. (f/k/a PIA Merchandising Services, Inc.) and SPAR Acquisition, Inc., consummated on July 8, 1999, has been accounted for as required under GAAP as a purchase by SPAR Acquisition, Inc. and its subsidiaries of PIA Merchandising, Inc. (SPAR Group, Inc. pre-merger) and its subsidiaries, with the books and records of the Registrant being adjusted to reflect the historical operating results of SPAR Acquisition, Inc. As a result, the quarter-to-quarter comparisons will not include any of the revenues and expenses of PIA Merchandising Services, Inc. (SPAR Group, Inc. pre-merger) prior to July 8, 1999 (including all of 1998), or any revenues or expenses of the business acquired by SPAR Performance Group, Inc., an indirect subsidiary of SPAR Group, Inc., prior to January 15, 1999 (including all of 1998), in the revenues and expenses of the SPAR Group prior to such dates. The Registrant cannot, at this time, present a reasonable estimate of the results of operations as an analysis of the financial treatment of certain matters has not been completed.
