                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1.   Basis of Presentation

     The accompanying unaudited consolidated financial statements have been
     prepared by the Company pursuant to the rules and regulations of the
     Securities and Exchange Commission.  Certain information and footnote
     disclosures normally included in annual financial statements have been
     omitted pursuant to such rules and regulations.  The Company believes the
     disclosures are adequate to make the information presented not misleading.
     The unaudited consolidated financial statements included herein are, in the
     opinion of management, prepared on a basis consistent with the audited
     consolidated financial statements for the year ended December 31, 1996 and
     include all adjustments (consisting only of normal recurring adjustments)
     necessary for a fair presentation of the information set forth.  Certain
     reclassifications have been made to the prior year financial statements in
     order to conform to the current year presentation.

     The quarterly results of operations are not necessarily indicative of
     results of operations for subsequent quarters or the full year.

     These unaudited consolidated financial statements should be read in
     conjunction with the audited consolidated financial statements and the
     notes thereto included in the Company's 1996 Annual Report to Stockholders.
 
2.   Acquisitions - Poolings of Interests
 
     During the six-month period ended June 30, 1997, the Company acquired
     substantially all of the net assets of Byerly & Company, Inc., Arnold &
     Company, Inc. and Trinder & Norwood, Inc. in exchange for 263,000 shares of
     its Common Stock.  These acquisitions were accounted for as poolings of
     interests.  The financial statements for all periods prior to the
     acquisition date (January 1, 1997) have been restated to include the
     operations of Byerly & Company, Inc.  Arnold & Company, Inc. and Trinder &
     Norwood, Inc. were not material to the Company individually or in the
     aggregate and accordingly, prior period financial statements were not
     restated.

     On April 2, 1997, the Company acquired a 50% interest in Wyatt Group Pty
     Ltd. and accounted for the acquisition as a purchase.  This transaction was
     not material to the Company.

     The following summarizes the restatement to reflect the acquisition of
     Byerly & Company, Inc.   (in thousands):

3.   Effect of New Pronouncements

     In February, 1997, the Financial Accounting Standards Board issued
     Statement No. 128 (SFAS 128), "Earnings Per Share", which is required to be
     adopted on December 31, 1997. At that time, the Company will be required to
     change the method currently used to compute earnings per share and to
     restate all prior periods. Under the new requirements for calculating
     primary earnings per share, the dilutive effect of stock options will be
     excluded. The impact is expected to result in an increase in primary
     earnings of $.05 and $.02 per share for the quarters ended June 30, 1997
     and 1996, respectively, and $.08 and $.05 per share for each of the six
     month periods ended June 30, 1997 and 1996, respectively. In addition, the
     impact of SFAS 128 is expected to result in an increase in fully diluted
     earnings per share of $.03 and $.01 per share for each of the quarters
     ended June 30, 1997 and 1996, respectively, and $.04 and $.01 per share for
     each of the six month periods ended June 30, 1997 and 1996, respectively.

                           ARTHUR J. GALLAGHER & CO.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Insurance premiums and risk management income reflect the overall pricing
pressure throughout the insurance premium marketplace. Although these conditions
are partially offset by the increases in investment and other income and a
reduction in the Company's effective income tax rate, the Company does not
anticipate any change in the near future in this extremely competitive
environment.

Commission revenues increased by 3% to $63.2 million in the second quarter of
1997 and by 1% to $126.5 million in the first half of 1997 over the respective
periods in 1996. These increases are due principally to new business production
partially offset by lost business.

Fee revenues increased by 4% to $43.4 million in the second quarter of 1997 and
by 6% to $85.1 million in the first six months of 1997 over the respective
periods in 1996. These increases reflect new business production and to a lesser
extent renewal fee increases of self-insurance products generated primarily by
Gallagher Bassett Services, Inc. (a Company subsidiary), partially offset by
lost business.

Investment income and other increased 57% to $10.0 million in the second quarter
of 1997 over the same period in 1996 due primarily to a $1.8 million gain
recognized in the second quarter on the restructuring of a long term lease for
facilities in the U.K. and $1.1 million of capital gains recognized on the sale
of assets during the second quarter. Investment income and other increased by
35% to $16.4 million in the first half of 1997 over the first half of 1996 due
primarily to the gains mentioned above and gains of $1.6 million on the sale of
assets and other investments recognized in the first quarter of 1997.

Total expenses decreased by 1% or $1.1 million in the second quarter of 1997
from the same period in 1996 and increased by 1% or $2.3 million in the first
half of 1997 over the same period in 1996.

Salaries and employee benefits decreased by $3.1 million or 5% to $58.0 million
in the second quarter of 1997 and decreased by $1.0 million or 1% to $119.2
million in the first six months of 1997 from the respective periods in 1996.
These decreases are due primarily to a $4.8 million non-recurring gain
recognized in the second quarter of 1997 from a restructuring and settlement of
a defined benefit pension plan at one of the Company's London subsidiaries
partially offset by salary increases and higher employee fringe benefit costs.

Other operating expenses increased by $2.0 million or 6% to $39.2 million in the
second quarter of 1997 and by 4% to $75.5 million in the first six months of
1997 over the respective periods in 1996. These increases are due primarily to
increases in rent and general office expenses related to new leases and office
expansions and increased business insurance costs. In addition, travel and other
direct employee expenses increased in 1997 due to the growth in sales volume.

The effective income tax rate of 34% for the second quarter and first six months
of 1997 is less than the statutory federal rate of 35% and is less than the
Company's effective tax rate of 39% for the second quarter and first six months
of 1996. These differences are due primarily to the effects of tax benefits
generated by certain investments.

Earnings per share for the second quarter of 1997 were $.73 compared to $.40 in
1996, an 83% increase. First half earnings per share increased 42% from $.89 in
1996 to $1.26 in 1997. These earnings per share increases reflect the non-
recurring gains discussed above and the reduction in the Company's effective tax
rate.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
           FINANCIAL CONDITION AND RESULTS OF OPERATIONS (CONTINUED)

FINANCIAL CONDITION AND LIQUIDITY

The insurance brokerage industry is not capital intensive.  The Company has
historically been profitable and positive cash flow from operations and funds
available under various loan agreements have been sufficient to finance the
operations and capital expenditures of the Company.  Cash generated from
operating activities was $35.1 million and $24.5 million for the six months
ended June 30, 1997 and 1996, respectively.  Because of the variability related
to the timing of fees receivable and premiums receivable and payable, cash from
operations for the Company can vary substantially from quarter to quarter.
Funds restricted as to the Company's use (primarily premiums held as fiduciary
funds) have not been included in determining the Company's liquidity.

The Company maintains a $20 million unsecured revolving credit agreement (the
"Credit Agreement") requiring repayment of any loans under the agreement no
later than June 30, 2001.  As of June 30, 1997, there were no borrowings
existing under this agreement.  The Company also has two term loan agreements
(the "Term Loan Agreements") that have outstanding balances of $630,000 and
$500,000 at June 30, 1997.  Loans under the Term Loan Agreements are repayable
in equal annual installments no later than January 11, 1998 and June 15, 1998,
respectively.  These borrowings were used to finance some of the Company's
alternative investments.

The Credit agreement and Term Loan agreements require the maintenance of certain
financial requirements.  The Company is currently in compliance with these
requirements.

The Company has line of credit facilities of $27.5 million which expire on April
30, 1998.  During the six months ended June 30, 1997, the Company borrowed and
repaid $15.9 million of short-term borrowings.  As of June 30, 1997, $10.0
million in short-term borrowings exists under these facilities.  These
borrowings were used to finance certain portfolios under the Company's strategy
of investment alternatives.

Through the first six months of 1997, the Company paid $9.8 million in cash
dividends on its common stock.  On May 21, 1997, the Company declared a regular
quarterly cash dividend of $.31 per share payable on July 15, 1997 to
Shareholders of Record as of June 30, 1997.  This is a 7% increase over the
quarterly dividend in 1996.

Net capital expenditures were $4.5 million and $5.1 million for the six months
ended June 30, 1997 and 1996, respectively.  In 1997, the Company expects to
make expenditures for capital improvements at least equal to the $10.2 million
spent in 1996.  Capital expenditures by the Company are related primarily to
expanded offices and updating computer systems and equipment.

In 1988, the Company adopted a plan which has been extended through June 30,
1998, to repurchase its common stock.  Through the first six months of 1997 and
1996, the Company repurchased 414,000 shares at a cost of $13.2 million and
609,000 shares at a cost of $19.9 million, respectively.  The repurchases are
held for reissuance in connection with exercises of options under its stock
option plans.  Under the provisions of the plan, the Company is authorized to
repurchase approximately 400,000 additional shares through June 30, 1998.  The
company is under no commitment or obligation to repurchase any particular amount
of common stock and at its discretion may suspend the repurchase plan at any
time.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

This quarterly report contains forward looking statements.  Forward looking
statements made by or on behalf of the Company are subject to risks and
uncertainties, including but not limited to the following:  the Company's
commission revenues are highly dependent on premiums charged by insurers, which
are subject to fluctuation; the property and casualty insurance industry
continues to experience a prolonged soft market despite high losses; continued
low interest rates will reduce income earned on invested funds; the insurance
brokerage and service businesses are extremely competitive with a number of
competitors being substantially larger than the Company; the alternative
insurance market continues to grow; the Company's revenues vary significantly
from quarter to quarter as a result of the timing of policy renewals and the net
effect of new and lost business production; the general level of economic
activity can have a substantial impact on the Company's renewal business.  The
Company's ability to grow has been enhanced through acquisitions, which may or
may not be available on acceptable terms in the future and which, if
consummated, may or may not be advantageous to the Company.  Accordingly, actual
results may differ materially from those set forth in the forward looking
statements.  Attention is also directed to other risk factors set forth in
documents filed by the Company with the Securities and Exchange Commission.
