         This Amendment No. 1 (the "Amendment") supplements and, as so

"Schedule 14D-9") by Data Research Associates, Inc., a Missouri corporation
("Data Research"), relating to the Agreement and Plan of Merger with SIRSI
Holdings Corp., a Delaware corporation (the "Parent"), and McGuire Acquisition

of May 16, 2001 and amended as of June 27, 2001, July 12, 2001 and July 24,
2001.

         All capitalized terms in this Amendment without definition have the
meanings attributed to them in the Schedule 14D-9.
