Services division and the Insurance and Education Services group. Actual results
for the six months ended December 31, 2002 include restructuring charges of $7.5
million or $0.06 per diluted share net of tax, related to the integration,
consolidation, and relocation of certain business operations, primarily as a
result of acquisition activity.

Excluding restructuring, impairment, and other charges, pro forma net income for
the six months ended December 31, 2003 was $39.3 million or $0.33 per diluted
share, as compared to pro



forma net income of $53.1 million or $0.44 per diluted share for the same period
