    --  Adjusted fourth quarter operating expense ratio shown on page 9 was 1.3
        pts lower than the same period in 2010.  This ratio was primarily
        impacted by reductions in travel and entertainment costs of 0.7 pts and
        business insurance of 0.6 pts.

Corporate Segment Fourth Quarter Highlights (continued)



    --   Clean energy investments -Gallagher holds investment
     positions in 14 commercial clean coal production plants that were
     built and first began production in 2009 (the 2009 Era Plants).
     These plants qualify for tax credits under Section 45 of the
     Internal Revenue Code which pass through proportionally to
     Gallagher's ownership level.

            Gallagher holds minority investment positions in 12 of the
            2009 Era Plants which are producing refined coal under long-
            term agreements with utilities.  At December 31, 2011,
            Gallagher's net carrying value of these investments was $8.9
            million and collectively they could generate approximately
            $4.3 million of net after-tax earnings per quarter through
       --   2019.
            Gallagher is currently seeking co-investors and long-term
            utility customers for the other two 2009 Era Plants.  At
            December 31, 2011, Gallagher's net carrying value of these
            investments was $1.5 million.  Gallagher cannot predict when
            these plants will resume production of refined coal or the
       --   amount of refined coal that will ultimately be produced.

        Gallagher holds investment positions in 15 commercial clean coal
         production plants that were built and first began producing refined
         coal in fourth quarter 2011 (the 2011 Era Plants).  These plants
         also qualify for tax credits under Section 45 of the Internal
         Revenue Code which pass through proportionally based on Gallagher's
         ownership level.

            At December 31, 2011, Gallagher holds majority investment
            positions in five of the 2011 Era Plants which are producing
            refined coal under long-term agreements with utilities.  At
            December 31, 2011, Gallagher's net carrying value of these
            investments was $23.6 million (on January 1, 2012 we sold
            ownership interests in these five investments for $12.9
            million) and collectively they could generate for Gallagher
            approximately $8.0 million of net after-tax earnings per
       --   quarter through 2021.
            Gallagher has non-binding agreements in principle with a
            utility and co-investors for one of the majority-owned 2011
            Era Plants.  This plant is expected to resume production of
            refined coal late in the second quarter of 2012.  At December
            31, 2011, Gallagher's net carrying value of this investment
            was $1.0 million.  Gallagher estimates that it will invest an
            additional net $2.0 million to house this plant prior to the
            resumption of production.  Once production resumes, it could
            generate for Gallagher approximately $1.7 million of net
       --   after-tax earnings per quarter through 2021.
            Gallagher is currently seeking co-investors and long-term
            utility customers for the other nine majority-owned 2011 Era
            Plants.  After co-investors' fundings, Gallagher intends on
            holding minority investment positions in these investments.
            At December 31, 2011, Gallagher's net carrying value of these
            investments was $8.8 million.  Gallagher estimates that it
            will invest an additional net $2.0 million to house each of
            these plants prior to the resumption of production.
            Gallagher cannot predict when these plants will resume
            production of refined coal or the amount of refined coal that
       --   will ultimately be produced.

        Gallagher holds a 42% controlling interest in Chem-Mod, LLC which
         possesses rights, information and technologies used for the
         reduction of unwanted emissions created during the combustion of
         coal.  The clean coal production plants discussed above, as well as
         other unrelated parties, license and use Chem-Mod's technologies
         in the production of refined fuel.  Based on current production
         estimates provided by licensees, Chem-Mod could generate for
         Gallagher approximately $2.5 million of net after-tax earnings per
         quarter.

        Please note that all estimates set forth above regarding the future
         quarterly earnings impact of our clean-energy investments are
         subject to significant risks, including those referred to below
         under "Information Regarding Forward-Looking Statements."
    --   Acquisition costs -Consists of professional fees and other
     due diligence costs related to acquisitions.
    --   Corporate -Consists of overhead allocations mostly related to
     corporate staff compensation.

Income Taxes

Gallagher allocates the provision for income taxes to its Brokerage and Risk Management segments as if those segments were computing income tax provisions on a separate company basis. Gallagher historically has reported, and anticipates reporting for the foreseeable future, an effective tax rate of approximately 38% to 41% in both its Brokerage and Risk Management segments. Gallagher's consolidated effective tax rate for the year ended December 31, 2011 and 2010 was 30.7% and 19.6%, respectively.

Please refer to Gallagher's filings with the SEC, including Item 1A, "Risk Factors," of its Annual Report on Form 10-K for the fiscal year ended December 31, 2010, for a more detailed discussion of these and other factors that could impact its forward-looking statements. Any forward-looking statement made by Gallagher in this press release speaks only as of the date on which it is made. Except as required by applicable law, Gallagher does not undertake to update the information included herein or the corresponding earnings release posted on Gallagher's website.

Information Regarding Non-GAAP Measures

In addition to reporting financial results in accordance with GAAP, this press release provides information regarding EBITDAC, EBITDAC margin, Adjusted EBITDAC, Adjusted EBITDAC margin, Adjusted EBITDAC margin excluding Heath Lambert, Diluted Net Earnings Per Share (As Adjusted) for the Brokerage and Risk Management segments, organic change in commission, fee and supplemental commission revenues, adjusted revenues, expenses and net earnings, adjusted compensation expense ratio and adjusted operating expense ratio. These measures are not in accordance with, or an alternative to, the GAAP information provided in this press release. Gallagher's management believes that these presentations provide useful information to management, analysts and investors regarding financial and business trends relating to Gallagher's results of operations and financial condition. Gallagher's industry peers may provide similar supplemental non-GAAP information, although they may not use the same or comparable terminology and may not make identical adjustments. The non-GAAP information provided by Gallagher should be used in addition to, but not as a substitute for, the GAAP information provided. Certain reclassifications have been made to the prior year amounts reported in this press release in order to conform them to the current year presentation.

Adjusted presentation - Gallagher believes that the adjusted presentation of 2011 and 2010 statements of earnings, presented on the following pages, provides stockholders and other interested persons with useful information regarding certain financial metrics of Gallagher that may assist such persons in analyzing Gallagher's operating results as they develop a future earnings outlook for Gallagher. The after-tax amounts related to the adjustments were computed using the normalized effective tax rate for each respective period.

    --  Adjusted revenues, expenses and net earnings - Gallagher defines these
        measures as revenues, expenses (including compensation expense and
        operating expense) and earnings from continuing operations,
        respectively, each adjusted to exclude gains realized from sales of
        books of business, supplemental commission timing amounts, workforce
        related charges, lease termination related charges, acquisition related
        integration costs, litigation settlements and adjustments to the change
        in estimated acquisition earnout payables, as applicable.  Acquisition
        related integration costs include costs related to transactions not
        expected to occur on an ongoing basis in the future once we fully
        assimilate the applicable acquisition.  These costs are typically
        associated with redundant workforce, extra lease space, duplicate
        services and external costs incurred to assimilate the acquisition on to
        our IT related systems.
    --  Adjusted ratios - Adjusted compensation expense ratio and adjusted
        operating expense ratio are defined as adjusted compensation expense and
        adjusted operating expense, respectively, each divided by adjusted
        revenues.

Earnings Measures - Gallagher believes that each of EBITDAC, EBITDAC margin, Adjusted EBITDAC, Adjusted EBITDAC margin, Adjusted EBITDAC margin excluding Heath Lambert, and Diluted Net Earnings Per Share (As Adjusted) for the Brokerage and Risk Management segments, as defined below, provides a meaningful representation of its operating performance. Gallagher considers EBITDAC and EBITDAC margin as a way to measure financial performance on an ongoing basis. Adjusted EBITDAC, Adjusted EBITDAC margin, Adjusted EBITDAC margin excluding Heath Lambert, and Diluted Net Earnings Per Share (As Adjusted) for the Brokerage and Risk Management segments are presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.

    --  EBITDAC - Gallagher defines this measure as earnings from continuing
        operations before interest, income taxes, depreciation, amortization and
        the change in estimated acquisition earnout payables.
    --  EBITDAC margin - Gallagher defines this measure as EBITDAC divided by
        total revenues.
    --  Adjusted EBITDAC - Gallagher defines this measure as EBITDAC adjusted to
        exclude gains realized from sales of books of business, supplemental
        commission timing amounts, earnout related compensation charges,
        workforce related charges, lease termination related charges,
        acquisition related integration costs, litigation settlements and the
        period-over-period impact of foreign currency translation.
    --  Adjusted EBITDAC margin - Gallagher defines this measure as Adjusted
        EBITDAC divided by total revenues, as adjusted to exclude gains realized
        from sales of books of business and supplemental commission timing
        amounts.
    --  Adjusted EBITDAC margin excluding Heath Lambert - Gallagher defines this
        measure as Adjusted EBITDAC further adjusted to exclude the EBITDAC
        associated with the acquired Heath Lambert operations divided by total
        revenues, as adjusted to exclude gains realized from sales of books of
        business, supplemental commission timing amounts and the revenues
        associated with the acquired Heath Lambert operations.

Information Regarding Non-GAAP Measures (continued)


    --  Diluted Net Earnings Per Share (As Adjusted) for the Brokerage and Risk
        Management segments - Gallagher defines this measure as net earnings
        adjusted to exclude the after-tax impact of gains realized from sales of
        books of business, supplemental commission timing amounts, workforce
        related charges, lease termination related charges, acquisition related
        integration costs litigation settlements and the change in estimated
        acquisition earnout payables divided by diluted weighted average shares
        outstanding.

Organic Revenues - Organic change in commission, fee and supplemental commission revenues excludes the first twelve months of net commission, fee and supplemental commission revenues generated from acquisitions accounted for as purchases and the net commission and 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 associated with the operations that were a part of Gallagher in both the current and prior year. In addition, organic growth excludes the impact of contingent commission revenues and the period-over-period impact of foreign currency translation. The amounts excluded with respect to foreign currency translation are calculated by applying 2011 foreign exchange rates to the same periods in 2010.

These revenue items are excluded from organic revenues in order to determine a comparable measurement of revenue growth that is associated with the revenue sources that will be continuing in 2011 and beyond. Gallagher has historically viewed organic revenue growth as an important indicator when assessing and evaluating the performance of its Brokerage and Risk Management segments. Gallagher also believes that using this measure allows financial statement users to measure, analyze and compare the growth from its Brokerage and Risk Management segments in a meaningful and consistent manner.

Reconciliation of Non-GAAP Information Presented to GAAP Measures - This press release includes tabular reconciliations to the most comparable GAAP measures for adjusted revenues, expenses and net earnings, EBITDAC (on pages 9 through 12), for Adjusted EBITDAC, Adjusted EBITDAC margin, Adjusted EBITDAC margin excluding Heath Lambert (on pages 3 and 4, respectively, for the Brokerage and Risk Management segments), for Diluted Net Earnings Per Share (As Adjusted) for the Brokerage and Risk Management segments (on pages 1 and 2), and for organic change in commission, fee and supplemental commission revenues (on pages 2 and 3, respectively, for the Brokerage and Risk Management segments).

    Notes to Fourth Quarter 2011
     Earnings Release

          Reported supplemental commission revenues recognized in 2011, 2010 and 2009 by quarter are shown in the financial supplement.
          As previously disclosed, many insurance carriers now provide sufficient information for Gallagher to recognize supplemental
          commission revenues on a quarterly basis for a majority of its 2011 and 2010 supplemental commission arrangements.  However, in
          2009 and prior years, most carriers only provided this information on an annual basis after the end of the contract period.
          Accordingly, the 2010 amounts reported in the table include both a full year of 2009 supplemental commission revenues and 2010
          supplemental commission revenues that were recognized by Gallagher on a quarterly basis.  This situation did not occur again in
          2011 and should not occur in 2012 or later years as Gallagher anticipates that most of the carriers will continue to provide
          information on a quarterly basis sufficient to allow recognition of revenues in a similar manner in future quarters.  The
    (1)   reported and adjusted supplemental commissions for 2011, 2010, 2009 and 2008 are as follows (in millions):
