     opinion of management, prepared on a basis consistent with the audited
     consolidated financial statements for the year ended December 31, 1995 and
     include all adjustments (consisting only of normal recurring adjustments)
     necessary for a fair presentation of the information set forth. Certain

     notes thereto included in the Company's 1995 Annual Report to Stockholders.
 
2.   ACQUISITIONS - POOLINGS OF INTERESTS
 
     On February 29, 1996, the Company acquired substantially all of the net
     assets of Levitt/Kristan Company. On May 31, 1996, the Company acquired
     substantially all of the net assets of Alliance Insurance Group, Inc.
     During the three month period ended September 30, 1996, the Company
     acquired substantially all of the net assets of Lamberson Koster & Company,
     Beymer & Bond Investigations, Inc., Morgan, Read & Coleman Limited and
     Morgan Insurance Services Limited. These acquisitions were made in exchange
     for 1,081,000 shares of the Company's Common Stock and were accounted for
     as poolings of interests. The consolidated financial statements for all
     periods prior to the acquisition dates have been restated to include the
     operations of these companies except for Alliance Insurance Group, Inc. and
     Beymer & Bond Investigations, Inc. which were not material to the Company.
 
     The following summarizes the restatement to reflect these acquisitions (in
     thousands):

                           ARTHUR J. GALLAGHER & CO.

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

FINANCIAL CONDITION AND LIQUIDITY

The insurance brokerage industry is not capital intensive. The Company has
historically been profitable with a positive cash flow from operations and has
consequently been able to finance its operations and capital expenditures from
internally generated funds. Funds restricted as to the Company's use (primarily
premiums held as fiduciary funds) have not been included in determining the
Company's liquidity.

During 1996, cash flow from operations and funds available under various loan
agreements have been sufficient to fund the operating and capital expenditures
of the Company. Cash generated from operating activities was $43.1 million and
$47.5 million for the nine months ended September 30, 1996 and 1995,
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.

The Company maintains a $20 million revolving credit agreement (the "Credit
Agreement") requiring repayment of any loans under the agreement no later than
June 30, 2001. As of September 30, 1996, there were no borrowings existing under
this agreement. The Company also entered into two term loan agreements (the
"Term Loan Agreements") that have outstanding balances of $1.3 million and $1.0
million at September 30, 1996. Loans under the Term Loan Agreements are
repayable in equal annual installments no later than January 11, 1998 and June
15, 1998, respectively.

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 also has line of credit facilities of $17.5 million and $10.0
million. Since the Company filed its 1995 Form 10-K Annual Report, it extended
its line of credit facility of $17.5 million to April 30, 1997. As of September
30, 1996, there were no borrowings existing under these line of credit
facilities.

Through the first nine months of 1996, the Company paid $12.8 million in cash
dividends on its common stock.  On September 17, 1996, the Company declared a
regular quarterly cash dividend of $.29 per share payable on October 15, 1996 to
Shareholders of Record as of September 30, 1996.

Net capital expenditures were $7.5 million and $8.9 million for the nine months
ended September 30, 1996 and 1995, respectively.  This decrease is primarily a
timing difference.  In 1996, the Company expects to make expenditures for
capital improvements at least equal to the $9.4 million spent in 1995.  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,
1997, to repurchase its common stock. Through the first nine months of 1996 and
1995, the Company repurchased 645,000 shares at a cost of $21.3 million and
187,000 shares at a cost of $6.7 million, respectively. The repurchases were
funded entirely by internally generated funds and 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
290,000 additional shares through June 30, 1997. 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.

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

RESULTS OF OPERATIONS

Insurance premiums and risk management income continue to come under extreme
pressure throughout the United States and abroad causing shortfalls in expected
commissions and fee growth. Although these conditions are partially offset by
the increases in investment and other income and a reduction in the Company's
overall tax rate related to that income, the Company does not anticipate any
change in the short term insurance markets, and does not expect 1996 fourth
quarter results to reach the levels attained during the fourth quarter of 1995.

Commission revenues decreased by 1% to $70.1 million in the third quarter of
1996. This decrease is due principally to renewal decreases and lost business
partially offset by new business production. Commissions revenues increased by
1% to $193.3 million in the first nine months of 1996. This increase is due
principally to new business production partially offset by lost business and
renewal decreases.

Fee revenues increased by 7% to $45.9 million in the third quarter of 1996 and
by 7% to $126.0 million in the first nine months of 1996 over the respective
periods in 1995. 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., partially offset by lost business.

Investment income and other increased 21% to $5.7 million in the third quarter
of 1996 and by 30% to $17.9 million in the first nine months of 1996 over the
respective periods in 1995. These increases were due primarily to significantly
higher returns on funds invested with outside fund managers.

Total expenses increased by 4% or $4.0 million in the third quarter of 1996 over
the same period in 1995 and increased by 4% or $10.8 million in the first nine
months of 1996 over the same period in 1995.

Salaries and employee benefits increased by $2.5 million or 4%, to $60.0 million
in the third quarter of 1996 and by $6.5 million or 4% to $177.7 million in the
first nine months of 1996 over the respective periods in 1995. These increases
are due principally to increased employee head count combined with salary
increases and higher employee fringe benefit costs partially offset by a
reduction in the Company's Incentive Compensation Plans due to commission
revenues which were lower than planned.

Other operating expenses increased by $1.5 million or 4% to $36.2 million in the
third quarter of 1996 and by 4% to $107.0 million in the first nine months of
1996 over the respective periods in 1995. These increases are due primarily to
increases in rent and general office expenses related to new and expanded
offices. Travel and other direct employee expenses were up due to the growth in
revenues and employee head count.

The effective income tax rate of 29% for the third quarter and 34% for the first
nine months of 1996 is less than the statutory federal rate of 35% and is less
than the Company's effective tax rate of 37% for the third quarter and 39% for
the first nine months of 1995 due primarily to the effect of the tax benefits of
certain investments.

Earnings per share for the third quarter of 1996 were $1.03 compared to $.94 in
1995, a 10% increase. In the first nine months, earnings per share increased 14%
from $1.73 in 1995 to $1.98 in 1996. These earnings per share increases reflect
the growth in revenues and a smaller growth in expenses noted above.

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.
