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.
