“Despite the softening rates in the insurance marketplace and the disruptions in our industry resulting from the ongoing investigations by state attorneys general and other regulatory agencies, Gallagher had another strong year,” said J. Patrick Gallagher, Jr., President and Chief Executive Officer. “On a combined basis, our Brokerage and Risk Management segments posted excellent results for the year:

• 18% growth in diluted net earnings per share,

• 11% growth in revenues, of which 6% is organic,

• 14% growth in pretax earnings, and

• 18% pretax margin, a 0.5 % improvement over 2003, despite margin drag of 0.3% related to expensing stock-based compensation, 0.3% related to foreign currency translation, 0.3% related to external Sarbanes-Oxley 404 implementation costs and 0.1% related to professional fees associated with recent insurance industry regulatory developments.”

Brokerage & Risk Management Segments Combined Fourth Quarter Highlights

• 12% growth in diluted net earnings per share.

• 11% growth in revenues, of which 3% is organic.

• 9% growth in pretax earnings.

• 19% pretax margin, despite margin drag of 0.5% related to external Sarbanes-Oxley 404 implementation costs, 0.5% related to professional fees associated with recent insurance industry regulatory developments, 0.5% related to increased amortization expense and 1.0% due to the compensation related matters discussed below in the Brokerage Segment Highlights.

Brokerage Segment Fourth Quarter Highlights

• 2% growth in diluted net earnings per share.

• 9% growth in revenues, of which -1% is organic.

• 20% pretax margin, despite margin drag of 0.6% related to external Sarbanes-Oxley 404 implementation costs, 0.6% related to professional fees associated with recent insurance industry regulatory developments, 0.6% related to increased amortization expense, and the compensation related items discussed below.

• Fourth quarter 2004 compensation ratio was 3.6% higher than fourth quarter 2003. A significant portion of the increase results from foreign currency translation of 0.4%, one-time charges related to staffing changes made in Gallagher’s London operations of 1.1% and 0.3% related to compensation levels of acquired operations.

• Closed five acquisitions and the pipeline remains strong.

• Contingent commissions were $8.2 million in fourth quarter 2004 versus $7.9 million in fourth quarter 2003. As previously announced, Gallagher will not enter into any new volume-based or profit-based contingent commissions agreements as a retail broker effective January 1, 2005. Accordingly, it is expected that future contingent commission revenues could be substantially reduced.

Risk Management Segment Fourth Quarter Highlights

• 55% growth in diluted net earnings per share.

• 16% growth in revenues; 15% growth in fees, all of which is organic.

• 58% growth in pretax earnings.

• 18% pretax margin.

Financial Services Segment Highlights

• During its third quarter conference call, Gallagher provided earnings guidance stating that the Financial Services Segment would report a loss of three to four cents per share in fourth quarter 2004. Actual results differed primarily because one Syn/Coal plant that generates installment sale gains was idle for approximately three weeks during the quarter due to equipment breakdowns and delays in the receipt of coal stock shipments.

• Synthetic fuel production in 2004 was ahead of prior year, resulting in a 20% effective tax rate for the company in 2004 versus 24% in 2003.

• Adoption of FIN 46 - In third quarter 2003, Gallagher adopted a new accounting pronouncement, FASB Interpretation No. 46 (FIN 46) - “Consolidation of Variable Interest Entities,” which required the company to consolidate one investment not previously consolidated because the company does not control the investment through a majority voting interest. Previously reported financial statements were not restated for the adoption of FIN 46. During third quarter 2004, Gallagher sold a portion of its interest in this investment, which eliminated the requirement to consolidate the investment under the FIN 46 rules. This investment is now accounted for using equity method accounting.

Legal Developments

As announced in its third quarter earnings conference call, in response to industry developments, Gallagher retained independent counsel to perform an internal review of certain of its business practices. Such independent counsel has completed its internal review and has found no evidence that Gallagher had engaged in any price fixing or bid rigging of the type alleged in the New York Attorney General ‘s October 14, 2004 complaint against Marsh & McLennan Companies, Inc. nor has it engaged in any improper tying arrangements. However, as part of insurance industry-wide investigations, Gallagher remains the subject of investigations and regulatory proceedings by authorities in fifteen states investigating certain of its business practices, including the receipt by Gallagher of contingent commissions. Gallagher is also a defendant in eight lawsuits brought by private litigants which relate to these practices. Gallagher cannot predict the outcome of these investigations, regulatory proceedings, and lawsuits, nor their effect upon Gallagher’s business or financial condition.

In addition, previously reported litigation involving synfuel technology reached the trial stage this month with a result expected in February 2005. The plaintiff seeks damages from Gallagher’s subsidiary, AJG Financial Services, Inc., in the amount of $140 million as well as a declaratory judgment that payments would be owing on future synfuel production through the end of 2007. AJG Financial Services, Inc. seeks damages in its counterclaim in the amount of $71 million. While management continues to believe the plaintiff’s claims lack merit, the outcome of this trial cannot be predicted.

Notes to Fourth Quarter 2004 Earnings Release and Non-GAAP Financial Measures

This exhibit contains supplemental non-GAAP financial information within the meaning of Regulation G of the SEC’s rules. Consistent with Regulation G, a description of such information is provided below and a reconciliation of certain of such items to U.S. generally accepted accounting principles (GAAP) is provided elsewhere in this press release. Gallagher believes the items described below provide meaningful additional information, which may be helpful to investors in assessing certain aspects of Gallagher’s operating performance and financial condition that may not be otherwise apparent from GAAP. Industry peers provide similar supplemental information, although they may not use the same or comparable terminology and may not make identical adjustments. This non-GAAP information should be used in addition to, but not as a substitute for, the GAAP information.

Non-GAAP Measures Defined

(1) Organic growth excludes the first twelve months of net commission and/or fee revenues generated from the acquisitions accounted for as purchases and the net commission and/or fee revenues related to operations disposed of in each year presented. These commissions and fees are excluded from organic revenues in order to determine the revenue growth that is associated with the operations that were a part of Gallagher in both the current and prior year.

(2) Represents year-to-date net earnings divided by total stockholders’ equity, less net balance of goodwill and amortizable intangible assets, as of the beginning of the year.

(3) Represents net earnings before the after-tax effect of investment gains (losses), depreciation, amortization, amortization of deferred compensation and restricted stock expense and stock compensation expense.

(4) Represents total stockholders’ equity less net balance of goodwill and amortizable intangible assets.

(5) Represents tangible net worth divided by the common shares outstanding at the end of the period.
