                                    (1 of 6)


Financial Services Segment Highlights - Third Quarter 2003

      o     We continue to reduce our investment holdings.
      o     Synthetic fuel production for the quarter was ahead of prior
            quarters, resulting in a 24% effective tax rate versus 30% in 2002.
      o     Prior year third quarter included non-recurring net investment
            losses of $20.2 million after tax, or $0.22 per diluted share.
      o     Adoption of FIN 46 - In the third quarter of 2003, the company early
            adopted a new accounting pronouncement, FASB Interpretation No. 46
            (FIN 46) - "Consolidation of Variable Interest Entities," which
            required the company to consolidate one partially-owned investment
            partnership not previously consolidated because it is not controlled
            by the company through a majority voting interest. The adoption of
            FIN 46 did not result in any additional debt on the company's
            balance sheet nor did it have any impact on its consolidated net
            earnings or stockholders' equity. The effect of consolidating this
            one investment partnership on the company's consolidated statement
            of earnings and balance sheet is shown on pages 3 and 6,
            respectively, of this earnings release.

"We are extremely pleased with the quarter-to-quarter improvement in our
Brokerage segment's pretax margin - up 6% over second quarter 2003 and up 10%
over first quarter 2003," said President and Chief Executive Officer, J. Patrick
Gallagher, Jr. "A solid quarter of 12% revenue growth on top of third quarter
2002's growth of 36% is an outstanding achievement by our Brokerage operations.
In the first 9 months of 2003, we grew revenues by 16% over the same period in
2002. When compared to the first 9 months of 2001, our Brokerage revenues have
grown $205.2 million, or 50%. Organic growth continues to be strong at 9% for
the quarter and 12% for the first 9 months of 2003. We applaud the success of
our employees, especially the new hires who have contributed greatly to this
growth."

"Our Risk Management segment has improved its growth rate and margins despite
the post-9/11 economic slow-down. This confirms Gallagher Bassett's continued
recognition as the best and most stable claims management services provider in
the business. Gallagher Bassett's clients receive great value from our efficient
operating platform and from the service provided by its rock-solid adjustors and
seasoned management team," added Mr. Gallagher.

"AJG is stronger than ever," said Mr. Gallagher. "We have a solid balance sheet
with over $400 million in tangible net worth. And, we distribute a significant
portion of our earnings back to our shareholders every year. Since our IPO,
we've increased our cash dividend, on average, 19% per year, and so far this
year we've used $51 million to repurchase 1.9 million of our shares."

The company will host a webcast conference call on Wednesday, October 22, 2003
at 9:00am EDT to further discuss these quarterly results. To listen, please go
