Record Date and Voting Securities

   The close of business on March 18, 2002 has been fixed as the record date
(the "Record Date") for the determination of stockholders entitled to notice of
and to vote at the Annual Meeting and any adjournment thereof. As of the Record
Date, the Company had 85,620,467 shares of Common Stock outstanding and
entitled to vote. Each share of Common Stock is entitled to one vote,
exercisable in person or by proxy. There are no other outstanding securities of
the Company entitled to vote, and there are no cumulative voting rights with
respect to the election of directors.

   The presence, in person or by proxy, of a majority of the outstanding shares
of the Common Stock of the Company is necessary to constitute a quorum at the
Annual Meeting. An automated system administered by the Company's transfer
agent tabulates the votes. Abstentions and broker non-votes are included in the
number of shares present and voting for the purpose of determining if a quorum
is present. Abstentions are also included in the tabulation of votes cast on
proposals presented to the stockholders but broker non-votes are not.

Expenses of Solicitation

   All expenses of the solicitation of proxies will be paid by the Company.
Officers, directors and employees of the Company may also solicit proxies by
telephone, facsimile or in person.

Board of Directors

   The Company's Board of Directors has the responsibility to review the
overall operations of the Company. The Board members are kept informed of the
Company's results of operations and proposed plans and business objectives by
the Company's management. During 2001, the Board of Directors met six times.
All of the directors attended at least 75% of those meetings and meetings of
the committees on which they served. Included among the committees of the Board
are standing Nominating, Audit and Compensation Committees.

Nominating Committee

   The Nominating Committee considers new nominees proposed for the Board of
Directors and will consider individuals whose names and qualifications are
furnished in writing to the Committee (in care of the

                                      4



Chairman at the Company's principal office) by stockholders. Current members of
the Nominating Committee are Robert E. Gallagher (Chairman), T. Kimball Brooker
and J. Patrick Gallagher, Jr. The Committee met four times in 2001. The
Company's By-Laws establish advance notice procedures with regard to the
nomination by a stockholder of a candidate for election as a director. In
general, notice must be received by the Company not less than 45 days prior to
an annual meeting of stockholders of the Company. Such notice must set forth
all information with respect to each such nominee as required by the federal
proxy rules. Such notice must be accompanied by a consent of such nominee to
serve as a director, if elected.

Audit Committee

   The Audit Committee of the Board of Directors is composed of 5 directors,
none of whom is an employee of the Company. The Committee is governed by a
charter approved by the Board of Directors on May 16, 2000. In accordance with
its Charter, the Committee assists the Board in carrying out its
responsibilities for monitoring management's accounting for the Company's
financial results and for the timeliness and adequacy of the reporting of those
results; discusses and makes inquiry into the audits of the Company's books
made internally and by outside independent auditors, the Company's financial
and accounting policies, its internal controls and its financial reporting; and
investigates and makes a recommendation to the Board each year with respect to
the appointment of independent auditors for the following year. Current members
of the Committee are Gary P. Coughlan (Chairman), T. Kimball Brooker, Ilene S.
Gordon, Robert Ripp and James R. Wimmer, each of whom meets the independence
and experience requirements of the New York Stock Exchange. The Audit Committee
met eight times in 2001.

   Notwithstanding anything to the contrary set forth in any of the Company's
filings under the Securities Act of 1933 or the Securities Exchange Act of 1934
that might incorporate filings, including this Proxy Statement, in whole or in
part, the following report shall not be incorporated by reference into any such
filings.

                         Report of the Audit Committee

   In discharging its oversight responsibility as to the audit process, the
Committee obtained from the independent auditors a formal written statement
describing all relationships between the auditors and the Company that might
bear on the auditors' independence consistent with Independence Standards Board
Standard No. 1 "Independence Discussions with Audit Committees" and discussed
with the auditors any relationships that may impact their objectivity and
independence. The Committee discussed and reviewed with the independent
auditors all communications required by generally accepted auditing standards,
including those described in Statement on Auditing Standards No. 61, as
amended, "Communication with Audit Committees". The Committee reviewed and
discussed the audited consolidated financial statements of the Company as of
and for the fiscal year ended December 31, 2001, with management and the
independent auditors.

   Management of the Company is responsible for the preparation, presentation
and integrity of the Company's financial statements, the Company's accounting
and financial reporting principles, and internal controls designed to assure
compliance with accounting standards and applicable laws and regulations. The
independent auditors are responsible for auditing the Company's financial
statements and expressing an opinion as to their conformity with accounting
principles generally accepted in the United States. Management has represented
to the Committee that the Company's financial statements were prepared in
accordance with generally accepted accounting principles. It is not the duty of
the Committee to plan or conduct audits or to determine that the Company's
financial statements are complete and accurate and in accordance with generally
accepted accounting principles.

                                      5



   Based on the above-mentioned review and discussions with management and the
independent auditors, the Committee recommended to the Board that the Company's
audited consolidated financial statements be included in its Annual Report on
Form 10-K for the fiscal year ended December 31, 2001, for filing with the
Securities and Exchange Commission.

filings under the Securities Act of 1933 or the Securities Exchange Act of 1934
that might incorporate filings, including this Proxy Statement, in whole or in
part, the following report and the Comparative Performance Graph on Page 11
shall not be incorporated by reference into any such filings.

                     Report of the Compensation Committee

Executive Compensation

   The Compensation Committee is responsible for determining the total
compensation, other than stock options, and employment conditions of the
Company's executive officers. In determining the total 2001 compensation, the
Compensation Committee generally evaluated the executive's contribution to the
overall success of the Company in achieving the corporate goals set out below.
In making such determinations, the members of the Compensation Committee
consult with members of senior management and base such determinations on the
information and recommendations of senior management. The business growth and
human resources goals were given less weight in determining the executive's
compensation than the earnings growth goal.

   Earnings Growth--Year-over-year earnings growth is one of the most important
   goals of the Company. The effort of an individual executive in meeting or
   exceeding year-over-year growth for his or her department or division has
   historically been an important criterion in the evaluation. However, in
   2001, the Compensation Committee focused on the contribution of the
   executive to the overall success of the Company in meeting its plan for
   growth. Longer term growth goals, as measured against the Company's Three
   Year Strategic Plan, are also considered in the evaluation. In 2001, the
   Company's net earnings increased 35% which surpassed the average annual
   growth rate for the period 1991 to 2000.

   Business Growth--The Company considers its long term business growth to be a
   critical factor in the continued success of the Company. Executives are
   expected to support the Company's acquisition program, which seeks to
   achieve growth by successfully integrating independent businesses into the

                                      6



   corporate structure. Similarly, establishment of operations in new
   geographic areas, as well as the successful development and marketing of new
   product lines, are considered necessary to the continued growth of the
   Company and are included in the evaluation. In 2001, sixteen businesses were
   acquired. The development and marketing of new product lines continued on a
   basis consistent with prior years. The Company believes that these efforts
   had a direct impact on the 14% increase in total revenues achieved in 2001
   over 2000.

   Human Resources--As a service business, the Company believes that its
   employees are its greatest asset. Over 60% of the Company's expenses in 2001
   were related to the compensation of its employees and related costs. The
   Company is committed to the successful hiring, training and retaining of
   people who promote the growth, financial success and management succession
   of the Company. An executive's ability to manage these resources, as well as
   the attendant expenses, is a significant criterion. In 2001, the Company's
   overall success in effectively managing its employees evidenced the
   commitment of the Company's executive officers, as a group, to the corporate
   goal of continuously improving the quality and efficiency of its human
   resources. This was demonstrated by the Company's ability to generate
   $140,000 in revenue per employee for 2001, one of the highest figures in the
   industry and an increase from the $139,000 in revenue per employee generated
   during 2000. This was accomplished even as the 2001 employee headcount
   increased by 14% over 2000.

   Enhancement of shareholder value is the ultimate goal of the Company. The
Compensation Committee believes that its focus on specific corporate goals
should result in a strong stock price, improved earnings per share and greater
return on stockholders' equity. Net earnings per share in 2001 increased by 34%
over 2000. This substantial increase was directly related to the efforts of the
Company's executive officers.

   The Company has a discretionary bonus pool for executive officers and key
employees, contingent upon satisfactory corporate growth and the attainment of
predetermined managerial goals. These predetermined goals are extremely varied
and, in the case of the executive officers, are established by the individual
officer in conjunction with senior management in consultation with the
Compensation Committee. The goals are too diverse to generalize but typically
include meeting or exceeding budgetary guidelines and contribution to the
Company's profitability. Attainment of these goals in many cases may be
determined by a subjective judgment of the individual supervisor or, in the
case of the executive officers, by the Compensation Committee. The eligibility
for participation in the bonus pool is determined by the Board. Approximately
50 officers and key employees, including Messrs. Gallagher and Cloherty, are
current participants in the discretionary bonus pool.

   The Company has adopted a bonus plan for its Brokerage Services Division to
provide incentives to the management personnel of the Division. The bonuses
under this Plan are determined by a formula applied to the pretax profitability
of the Brokerage Services Division. Under the Plan, participants can elect to
receive their award in cash or in Company stock. Any stock award will be
credited to the participant at 85% of the market price at date of award and
will vest in the participant's account over a three year period at the rate of
33 1/3% per year, with vesting acceleration in the event of death, disability
or retirement. Messrs. Braniff, McGurn and Cloherty are eligible to participate
in this Plan, although Mr. Cloherty was not paid a bonus under this Plan for
the years 2000 and 2001.

   The Company has adopted the AJG Financial Services Bonus Plan applicable to
the members of the Company's investment team. The Board of Directors and the
Compensation Committee approved this Plan in order to provide incentives to the
investment team to continue to generate investment gains for the Company. This
Plan provides generally that 20% of the extraordinary investment gains and tax
benefits generated by transactions initiated by the investment team are to be
allocated to the four key officers of the investment

                                      7



team, including Michael J. Cloherty, Chairman and Chief Executive Officer of
AJG Financial Services, Inc. and Executive Vice President and Chief Financial
Officer of the Company. Under the Plan, payments to the team in any one year
are to be not more than $10 million and are to be deferred over a three year
period of installment payments unless other arrangements are agreed to by the
Company and the respective members of the investment team. In addition, bonuses
under this Plan may be deferred by agreement of the Company and a participant
in whole or in part under the AJG Financial Services Bonus Deferral Plan with
vesting schedules as determined by the Company and the participant under the
Deferral Plan.

   The Company has adopted the Deferred Equity Participation Plan to encourage
key executive officers to remain with the Company until their normal
retirement. Under the Plan, the Company contributes shares of Common Stock in
an amount approved by the Compensation Committee. The Chief Executive Officer
of the Company, in conjunction with the Compensation Committee, determines the
key executives that will receive an award under the Plan and the amount of such
award. Distributions under the Plan may not be made until the participant
reaches age 62 and are subject to forfeiture in the event of a voluntary
termination of employment prior to age 62. All distributions are made in the
form of Common Stock of the Company.

   Option grants to executive officers under the Company's Stock Option Plans
are determined by the Option Committee of the Board of Directors and are
generally based upon more subjective factors than those used by the
Compensation Committee. The Option Committee considers the recommendations of
the executive officers of the Company, the responsibilities of each grantee,
his or her past performance and his or her anticipated future contribution to
the Company. Options directly reflect the Company's performance through its
stock price.

   The Internal Revenue Code limits the deductibility for federal income tax
purposes of certain compensation payable to top executive officers of publicly
held corporations. Certain types of compensation are excluded from the
limitations. The Company generally attempts to preserve the federal income tax
deductibility of compensation paid when it is appropriate and is in the best
interests of the Company and its stockholders. However, the Company reserves
the right to authorize the payment of nondeductible compensation which it deems
appropriate.

   Executive officers participate in the Savings and Thrift Plan, Supplemental
Savings and Thrift Plan and Pension Plan, as well as customary employee health
benefits and expense reimbursement in accordance with the Company's policy.

   During 2001, the Committee compared the compensation of the six most highly
compensated executive officers of the Company to the publicly held competitors
of the Company included in the Comparative Performance Graph on Page 11. The
Committee targets the middle of its competitors' salary range for its executive
officers' compensation. The Committee believes that the 2001 compensation of
the Company's six most highly compensated executive officers will be in the
middle range when compared to its publicly-held competitors after making
certain adjustments for the size of the Company.

Chief Executive Officer Compensation

   The 2001 salary of J. Patrick Gallagher, Jr., the Company's Chief Executive
Officer, was $850,000. Mr. Gallagher received a restricted stock award of
$1,059,000 and an award of $400,000 under the Company's Deferred Equity
Participation Plan for 2001 and a bonus of $500,000 under the Company's
discretionary

                                      8



bonus pool and an award of $400,000 under the Deferred Equity Participation
Plan for 2000. In determining Mr. Gallagher's salary and bonus, the
Compensation Committee considered the Company's excellent performance in 2001
and 2000 with reference to substantial increases in net earnings per share.

   Company's Supplemental Savings and Thrift Plan in 2001 (Mr.
   Gallagher--$23,600, Mr. Cloherty--$13,900, Mr. Braniff--$14,300, Mr.
   Durkin--$7,100, Mr. McGurn--$7,400 and Mr. McKenna--$7,200) and the

   Durkin--$1,200, Mr. McGurn--$1,100 and Mr. McKenna--$1,200).

(3) Represents amounts awarded under the Company's Deferred Equity
    Participation Plan. Amounts shown do not represent actual payments to the
    executive officer. Participation in the Plan by any person, and the amount
    of such participation, is at the sole discretion of the Company's Chief
    Executive Officer, in conjunction with the Compensation Committee. The Plan
    provides that the Company will contribute to the Plan shares of Common
    Stock in an amount approved by the Compensation Committee. All funds
    allocated by the Company to the Plan will be used to purchase Common Stock.
    Prior to payout, the participant is not entitled to vote, dispose of or
    receive dividends with respect to such shares, and shares are subject to
    forfeiture under certain conditions, including but not limited to, the
    participant's voluntary termination of employment with the Company prior to
    age 62. A participant will be eligible to receive a distribution from the
    Plan upon reaching age 62. All distributions will be made in the form of

    three year period in equal parts. Such awards include the dividends
    associated with the underlying stock.

(5) Mr. Cloherty agreed to waive his right to receive any bonus from the
    Company for 2000. In consideration for such waiver, on March 15, 2001, the
    Company paid Mr. Cloherty a waiver fee of $165,200 and loaned Mr. Cloherty
    the principal amount of $2,382,900. Under Mr. Cloherty's promissory note,
    repayment of the outstanding principal amount plus interest at the annual
    rate of 5.2% is payable upon demand of the Company. The Company has agreed
    to forgive repayment of the principal amount of the loan plus interest on
    an annual basis at the rate of 33 1/3 percent per year beginning in 2002 so
    long as Mr. Cloherty remains employed by the Company or retires in
    accordance with the Company's retirement plan. In the event Mr. Cloherty
    voluntarily terminates his employment with the Company (other than for
    retirement) or Mr. Cloherty's employment is terminated for cause by the
    Company, the outstanding principal amount of the loan becomes immediately
    due and payable. In addition, Mr. Cloherty has a loan in the principal
    amount of $40,000 in connection with his relocation to Illinois in 1983
    which is payable on demand and is without interest.

(6) The Company has an Employment Agreement with James J. Braniff III ending on
    December 31, 2003. Under the Agreement, Mr. Braniff is to receive an annual
    salary of not less than $600,000 and is entitled to participate in the
    Brokerage Services Division Management Bonus Plan. On January 1, 2001, Mr.
    Braniff was indebted to the Company in the principal amount of $1,039,500,
    which accrued interest at the annual rate of 3%. During 2001 the Company
    forgave $146,685 of principal and interest in connection with such
    indebtedness which amount is included in his compensation for 2001. During
    2000 the Company forgave $233,900 of principal and interest in connection
    with such indebtedness which amount is included in his compensation for
    2000. Under the Agreement, $115,500 of Mr. Braniff's indebtedness is to be
    forgiven annually while Mr. Braniff is an employee of the Company. In
    addition, Mr. Braniff has a loan in the principal amount of $80,000 in
    connection with his relocation to Illinois which is payable on demand and
    is without interest.

Directors' Compensation

   Directors who are officers of the Company receive compensation in their
capacities as officers and receive no additional compensation for serving as
directors.

   Non-employee directors, currently Messrs. Brooker, Coughlan, Ripp and Wimmer
and Ms. Gordon, are eligible to receive compensation consisting of nonqualified
stock options. In addition, non-employee directors receive an annual retainer
of $25,000 per year or, in lieu of the cash retainer, an option to purchase
shares of the Company's Common Stock below market value, plus fees of $500 for
attendance at each Board meeting or committee meeting on a date other than a
Board meeting date. Non-employee directors are reimbursed for travel and
accommodation expenses incurred in attending Board or committee meetings.
Non-employee directors are not eligible for participation in any other
compensation plans of the Company.

   In 1989, the Company's stockholders approved the adoption of the Company's
1989 Non-Employee Directors' Stock Option Plan (the "1989 Plan"), which has
been subsequently amended. The 1989 Plan currently provides that non-employee
directors are eligible to be granted nonqualified options to purchase a maximum
of 1,325,000 shares of the Company's Common Stock. The 1989 Plan encompasses
options granted to non-employee directors at the discretion of the Option
Committee of the Company's Board of Directors ("Discretionary Options") and
options granted to non-employee directors pursuant to an election made by a
non-employee director to receive options in lieu of his or her annual retainer
("Retainer Options"). Shares issued upon exercise of options granted under the
1989 Plan may be repurchased shares held by the Company or authorized but
previously unissued shares.

                                      11



   Under the 1989 Plan, a Discretionary Option shall be exercisable at such
rate and price fixed by the Option Committee. Discretionary Options terminate
if not exercised by the date set forth in the 1989 Plan or by such date
established by the Option Committee at the time it makes the grant.

   Pursuant to the terms of the 1989 Plan, Messrs. Coughlan and Wimmer and Ms.
Gordon have elected to receive their annual retainers for 2002 in the form of
an option to purchase the Company's Common Stock. Each year on or before two
weeks preceding the Company's Annual Meeting of Stockholders, the Option
Committee shall determine the number of shares of Common Stock with respect to
which a non-employee director may be granted a Retainer Option. The
non-employee director's option exercise price per share shall be equal to the
Fair Market Value of the Common Stock subject to the Retainer Option less the
Annual Retainer, divided by the number of shares subject to the Retainer
Option. The option exercise price per share shall be not less than the par
value of the Common Stock. "Fair Market Value" is defined as the closing price
of the Company's Common Stock as reported on the New York Stock Exchange
composite listing for the day on which the option is granted.

   On May 22, 2001, the Company granted a Retainer Option for 1,000 shares of
the Company's Common Stock to Messrs. Coughlan, Ripp and Wimmer and Ms. Gordon
at an exercise price of $1.11 per share. Such options are exercisable at the
rate of one-fourth of such grant each successive quarter commencing August 22,
2001. In addition, on May 22, 2001, the Company granted a Discretionary Option
for 25,000 shares of the Company's Common Stock to each of Messrs. Brooker,
Coughlan, Ripp, and Wimmer and Ms. Gordon at an exercise price of $26.11 per
share, which was the closing price for a share of Common Stock as reported on
the New York Stock Exchange composite listing on that date. Such options are
exercisable at the rate of one-third of such grant each successive May 22,
commencing May 22, 2002.

   The Company approved a supplemental deferred compensation arrangement,
effective July 1, 1996, with Robert E. Gallagher after his retirement, and to
his surviving spouse after his death, and the surviving spouse of John P.
Gallagher, providing for a payment of $100,000 annually, inclusive of any
Company pension plan payments, to be paid until the death of each such
beneficiary.

Pension Plan

   The Company also maintains a non-contributory defined benefit pension plan
covering substantially all domestic employees which is qualified under the
Internal Revenue Code. The plan provides an annual pension benefit on normal
retirement at age 65 which, when paid in the form of a single life annuity,
will equal 1% of final average earnings multiplied by the number of years of
credited service, not to exceed 25 years (without any deduction for social
security or other offset amounts). A person's earnings for purposes of the plan
include all compensation other than allowances such as moving expenses plus any
pre-tax contributions under the 401(k) feature of the Savings and Thrift Plan,
less pre-tax contributions under the Supplemental Savings and Thrift Plan.
Effective for plan years beginning after 1988, the maximum includible
compensation for a participant for any year may not exceed an overall salary
maximum as determined by the Internal Revenue Service of $200,000 in 2002. The
remuneration for executive officers shown under "Salary" and "Bonus" in the
Summary Compensation Table constitutes their earnings during 2001 for purposes
of the plan without regard to the Internal Revenue Service's limitation. "Final
average earnings" are the highest average earnings received in any five
consecutive full calendar years before retirement. Employees' pension rights
are fully vested after the earlier of (i) 5 years of service with the Company
or (ii) the attainment of age 65.

   The following table shows the estimated annual benefits (which are not
subject to deduction for social security or other offset amounts) payable on
retirement under the Company's defined benefit plan to persons in specific
remuneration and credited years of service classifications assuming (i) the
person elects the single

                                      12



life annuity basis providing monthly payments without benefits to his survivors
and (ii) the person continues in the employ of the Company at his present rate
of remuneration until age 65:

addition to amounts payable to such persons under the Company's Savings and
Thrift Plan and Supplemental Savings and Thrift Plan on their retirement and
are subject to certain limitations as required under the Internal Revenue Code.

Stock Option Plans

   The Company maintains a 1988 Incentive Stock Option Plan and a 1988
Nonqualified Stock Option Plan.

   The following table sets forth certain information regarding options to
purchase shares of Common Stock granted to the executive officers of the

Severance Arrangements

   The Company has a plan for severance compensation to employees after a
hostile takeover. The plan defines a hostile takeover to include, among other
events, the following events, if not approved by two-thirds of the members of
the Board of Directors in office immediately prior to any such events: the
election of directors not nominated by the Board of Directors, a business
combination, such as a merger, not approved by the holders of 80% or more of
the Common Stock and the Board of Directors or not meeting various "fair price"
criteria, or the acquisition of 20% or more of the combined voting power of the
Company's stock by any person or entity. All full-time and part-time employees
who are regularly scheduled to work 20 or more hours per week and who have
completed at least two years of continuous employment with the Company are
participants in the plan. A severance benefit is payable under the plan if a
participant's employment with the Company terminates voluntarily or
involuntarily within two years after a hostile takeover for reasons such as
reduction in compensation, discontinuance of employee benefit plans without
replacement with substantially similar plans, change in duties or status,
certain changes in job location and involuntary termination of employment for
reasons other than just cause. For participants who have completed two but less
than five years of employment, the benefit is equal to the employee's annual
compensation during the year immediately preceding the termination of
employment. For employees who have completed five or more years of employment,
the benefit is equal to two and one-half times the employee's annual
compensation during the 12 months ending on the date of termination of
employment, but may not exceed 2.99 times average annual compensation during
the preceding five years. Annual compensation is defined for purposes of the
plan as the amount of the employee's wages, salary, bonuses and other incentive
compensation. Benefits are payable in a lump sum not later than 10 days after
termination of employment.

   Each of the executive officers of the Company named in the Summary
Compensation Table has entered into a change in control agreement with the
Company. A severance benefit is payable under the agreement if

                                      14



the executive officer's employment with the Company is terminated by (i) the
Company for any reason other than death, physical or mental incapacity, or
cause within 24 months following a change in control of the Company; or (ii)
the resignation of the executive officer within 24 months following a change in
control of the Company upon the occurrence of a material change in the nature
or scope of the executive's authorities, powers, functions or duties or a
reduction in the executive's total compensation. In the event of any such
termination of the executive officer's employment, under the agreement the
Company is required to pay the executive a severance allowance equal to his
then salary and bonus payments for a 24 calendar month period. Additionally,
the executive will also continue to participate for a period of two years in
the Company's welfare benefit plans. Cash benefits are payable in a lump sum
not later than seven days after termination of employment.

                PROPOSAL 2--RATIFICATION OF THE APPOINTMENT OF
                      ERNST & YOUNG LLP AS THE COMPANY'S
                   INDEPENDENT AUDITORS FOR THE FISCAL YEAR
                           ENDING DECEMBER 31, 2002

   The Audit Committee has considered the qualifications of Ernst & Young LLP
and recommended that the Board of Directors appoint them as independent
auditors of the Company for the fiscal year ending December 31, 2002. The Board
of Directors desires to obtain stockholders' ratification of the Board's action
in such appointment. A resolution ratifying the appointment will be offered at
the meeting. If the resolution is not adopted, the adverse vote will be
considered as a direction to the Board to select other auditors for the
following year. Because of the difficulty and expense of making any
substitution of auditors so long after the beginning of the current year, it is
contemplated that the appointment for the year 2002 will stand unless the Board
finds other good reason for making a change.

   Fees paid to Ernst & Young LLP for professional services rendered to the
Company during 2001 were as follows: Audit Fees $561,000 and All Other Fees
$1,105,000, including audit related services of $417,000 and other non-audit
related services of $688,000. Audit related services primarily include fees for
employee benefit plan audits, accounting consultations, other attest services
for certain subsidiaries and due diligence procedures. No services were
performed or fees incurred in connection with financial information systems
design and implementation projects during 2001. The Audit Committee considered
the effects that the provision of non-audit services may have on the Company's
independent auditors' independence.

   A representative of Ernst & Young LLP will be present at the Annual Meeting
to respond to appropriate questions and to make a statement if the
representative so desires.

   Ratification requires the affirmative vote by holders of at least a majority
of the outstanding shares voting at the Annual Meeting.

                THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE
                IN FAVOR OF RATIFICATION OF THE APPOINTMENT OF
                      ERNST & YOUNG LLP AS THE COMPANY'S
                         INDEPENDENT AUDITORS FOR 2002

          SUBMISSION OF STOCKHOLDER PROPOSALS FOR 2003 ANNUAL MEETING

   Stockholder proposals to be presented at the 2003 Annual Meeting of
Stockholders must be received by the Company at its principal office on or
before December 6, 2002 to be considered for inclusion in the

                                      15



Company's proxy materials for that meeting. With respect to any stockholder
proposal to be presented at the 2003 Annual Meeting of Stockholders that is
received by the Company after February 19, 2003, the proxies solicited on
behalf of the Board of Directors may exercise discretionary voting power.

                                 OTHER MATTERS

   The Company knows of no other matters to be presented for action at the
meeting. If any other matters should properly come before the meeting or any
adjournment thereof, such matters will be acted upon by the persons named as
proxies in the accompanying proxy according to their best judgment in the best
interests of the Company.

   The Annual Report to Stockholders containing financial statements for the
year ended December 31, 2001, and other information concerning the Company is
being furnished to the stockholders but is not to be regarded as proxy
soliciting material.

   Each stockholder is urged to mark, date, sign and return the enclosed proxy
card in the envelope provided for that purpose. Your prompt response is helpful
and your cooperation will be appreciated.
