                                    PART I

ITEM 1.  BUSINESS.


     The Registrant is an insurance holding company.  Incorporated in 1979, it
is the parent corporation of long established and more recently formed
companies.  Rollins Hudig Hall Holdings b.v., the Registrant's principal
European commercial insurance brokerage subsidiary, traces its origin back to
1688.  The Life Insurance Company of Virginia, another of Registrant's principal
subsidiaries, was incorporated in 1871.  It, along with subsidiaries Combined
Insurance Company of America and Union Fidelity Life Insurance Company/1/ engage
in the marketing of life and accident and health insurance products.  Virginia
Surety Company, Inc., Dearborn Insurance Company and London General Insurance
Company, Ltd., also subsidiaries, offer specialty property and casualty
insurance products.  Aon Risk Services, Inc., Aon Specialty Group, Inc., Rollins
Hudig Hall Holdings b.v., Godwins International, Inc., Nicholson Leslie Group,
Limited and Rollins Hudig Hall Co., subsidiaries of Registrant's wholly-owned
subsidiary, Rollins Hudig Hall Group, Inc., provide reinsurance intermediary
services, benefits consulting and commercial insurance brokerage services.

     The Registrant hereby incorporates by reference pages 15 through 19 and 21
through 25 of the Annual Report to Stockholders of the Registrant for the year
1994 ("Annual Report").

Competition and Industry Position


(1) INSURANCE BROKERAGE AND CONSULTING SERVICES


     Rollins Hudig Hall Co. ("RHH"), Rollins Hudig Hall Holdings b.v. ("Hudig"),
Aon Risk Services, Inc. ("ARS"), Aon Specialty Group, Inc. ("ASG"), Godwins
International, Inc. ("Godwins") and Nicholson Leslie Group, Limited ("NL").


     Rollins Hudig Hall Group, Inc., ("RHH Group"), is a holding company for the
Registrant's commercial brokerage and consulting operation.  RHH Group is the
third largest brokerage and consulting services firm in the world.  In early
1993, the Registrant completed the acquisition of the remaining outstanding
interest in its London-based wholesale broker, Nicholson Leslie Group, Limited
(formerly Nicholson Chamberlain Colls Limited.)  The RHH Group companies have
offices around the world and employ more than 13,000 professionals and support
personnel who serve the diverse needs of the Registrant's growing multinational
client base.


     RHH is ranked second among commercial insurance brokerage firms in the
United States in terms of gross revenues (Business Insurance, July 18, 1994).
Its subsidiaries operate in a highly competitive industry and compete with a
large number of insurance brokerage and agency firms as well as individual
brokers and agents and direct writers of insurance coverage.  RHH subsidiaries
offer comprehensive services to clients which range from small businesses to
major corporations, including placement of all lines of insurance, actuarial

------------
/1/The Registrant's Union Fidelity Life Insurance Company subsidiary and its The
Credit Life Insurance Company subsidiary merged in 1993 and all lines of
business conducted by the separate companies prior to the merger are now
conducted by Union Fidelity Life Insurance Company.



                                       2

services, proprietary risk management information systems, captive management,
and risk management and loss control consulting. It has also developed certain
specialist niche areas such as marine, aviation, directors and officers
liability, financial institutions, construction, energy, public entities,
leisure, entertainment and fine art. Hudig traces its commercial broking roots
to 1688 and is one of the premier brokers in Continental Europe with some 70
European offices and approximately 2,100 employees. Hudig has subsidiaries in
more than thirty countries and, together with an unaffiliated English broker, is
part of a joint venture that owns a network of insurance broking offices in
Southeast Asia.

     RHH and Hudig operate through subsidiaries with owned offices in North
America and Europe, as well as in the Far East, the Middle East, Central and
Latin America, and Australia. RHH is actively pursuing expansion in Latin
America and the far East. During 1994, Hudig subsidiaries opened offices in
Russia, Finland, Turkey, Portugal and Slovakia, and expanded its rapidly growing
European art brokerage business, operating under the name ArtScope, with
acquisitions of specialized art brokers in France and Germany. Together with its
Huntington T. Block operation in Washington, D.C. RHH is now one of the leading
art brokerage specialists in the world. RHH also acquired an Australian broker
specializing in group programs, making RHH one of the largest such brokers in
that part of the world.
 
     ARS offers creative, flexible and economical solutions to clients requiring
alternative risk services.  ARS subsidiaries, Aon Re Inc., formerly Aon
Reinsurance Agency, Inc. ("Aon Re") and Aon Risk Consultants, Inc., specialize
in providing reinsurance brokerage and consulting services. Aon Re ranked second
in 1993 among United States reinsurance intermediaries in terms of gross
revenues as published in Business Insurance (October 31, 1994).
 
     Aon Re Worldwide, formed in 1993 to bring together all the reinsurance
operations of ARS, has become one of the top reinsurance intermediaries in the
world.  The captive management and alternative market services in Europe were
combined under the name Aon Risk Services (Europe).  In 1994, new offices were
opened in Luxembourg and The Netherlands.  Agricultural Risk Management in
London, specializing in the evaluation of agricultural risk, was acquired in
early 1995.  Through Aon Risk Consultants, ARS offers actuarial expertise,
catastrophe modeling and alternative risk financing products to the global
marketplace.  SLE Worldwide is a leading managing general underwriter in the
sports, leisure and entertainment industries, both domestically and abroad.

     ASG addresses the highly specialized product development, consulting and
administrative needs of associations, affinity groups and financial services
companies nationwide.  ASG operating subsidiaries market and broker both the
primary and reinsurance risks of these programs.  Go Pro, Inc. acts as an
underwriting manager for property and liability programs for government
entities, public officials, school boards and law enforcement agencies.  Aon
Direct Group is ASG's direct marketer of specialty insurance products for
associations and affinity groups.
 
     Media/Professional Insurance (M/PI), a division of Aon Direct Group, is one
of the largest providers of libel and other insurance to the broadcast and print
media in the United States.  Its Bankers Insurance Service Corp. subsidiary is
an underwriting manager that serves the mortgage banking industry.  Its
Scarborough & Co. subsidiary provides similar underwriting services to community
banks, mortgage and savings institutions.

     ASG formed the Aon Alliance in 1993 to bring together expertise from
throughout the Registrant's operating subsidiaries to deliver value-added
service to the health-care industry, especially hospitals.  The Aon Alliance
provides professional liability insurance, software systems, reinsurance,
benefits, risk management, claims investigation, workers' compensation, retail
brokerage services and underwriting management.  As part of its overall health-
care strategy, ASG, in 1994, acquired OUM & Associates, an underwriting manager
and program administrator with a specialization in medical malpractice
coverages.

                                       3

     Employee training has long been an area of expertise for Aon companies, and
the 1994 acquisition of Pecos River Learning Centers, Inc. extends that
expertise into a broad range of industries, including some of the largest
multinational corporations.  Further, it builds upon a tradition of nationally
recognized customer-satisfaction consulting and training programs developed for
the automobile industry by Ryan Insurance Group, Inc. subsidiaries.

     The Registrant serves the employee benefits needs of clients around the
world through subsidiaries of Godwins and through the European benefits
operations of Hudig.  Godwins and its affiliated subsidiaries do business as
Godwins Booke and Dickenson ("GBD"), and serve the United States and Latin
America.  GBD was formed after the July 1, 1993 merger with Booke & Company
Inc., an actuarial and employee benefits consulting firm.
 
     In the United States, the benefits environment continues to change as
companies look for ways to manage their benefits costs while increasing the
choices offered to their employees.  GBD, with its expertise in all areas of
benefits and compensation, and its access to the Registrant's other
subsidiaries, is well-positioned to serve this market.  Existing business
continued to be influenced by a sluggish benefits consulting environment in the
United States.  Benefits issues in foreign countries are becoming more
complicated, and Hudig and Godwins anticipates increased demand for their
services in these markets. 

     The late-1994 acquisition of HRStrategies Inc. marks an important expansion
for GBD.  HRStrategies specializes in human resources strategy development,
employee selection, and identification and development of employee skill and
skills assessment systems.  As employers contend with a steadily shrinking
skilled labor pool, the ability to identify, motivate and compensate the skilled
worker becomes increasingly important.

     NL is a London based Lloyd's broker that was formed as a result of
Nicholson Chamberlain & Coll's 1993 acquisitions of the assets of Leslie &
Godwins and the remaining outstanding shares of Nicholson Chamberlain & Colls.
It places wholesale and reinsurance business in the London and international
markets, serving the needs of a wide range of clients around the world.  A
significant majority of NL's revenue is derived from sources unaffiliated with
Aon.

     During 1994, Aon acquired Lloyd's broker Jenner Fenton Slade Group Limited
(JFS), a premier energy insurance and reinsurance brokerage firm.  The
acquisition of JFS expands the expertise of Aon in this important and growing
area.  The energy brokerage operations of NL will be integrated into JFS.


(2) LIFE INSURANCE


     The Life Insurance Company of Virginia ("LOV"), Combined Insurance Company
of America ("Combined Insurance"), Combined Life Insurance Company of New York
("CLICNY"), Globe Life Insurance Company ("Globe") and Union Fidelity Life
Insurance Company ("Union Fidelity").
 
     The Registrant's life insurance subsidiaries are part of a highly
competitive industry.  LOV is the Registrant's principal life company.  LOV and 
its broker-dealer subsidiary conducts operations through a combination of branch
offices, independent broker arrangements, national and regional stock brokerage
houses and financial institutions.  Collectively, LOV operates through 150
career and independent agencies with approximately 386 field representatives and
has contracts with approximately 17,000 independent brokers.  LOV also operates
through 159 national and regional stock brokerage houses and 7 financial
institutions and has contracts with some 17,000 stockbrokers and representatives
in financial institutions.  LOV's franchise distribution system, the Forth
Financial Network, operates through 28 franchises supporting approximately 400
agents

                                       4
<PAGE>
 
marketing capital accumulation and traditional life products underwritten by
LOV and unrelated insurers. Business written by LOV includes a complete
portfolio of regular ordinary life insurance, individual and group annuities,
group life and group disability, variable life, variable annuities and universal
life coverages. In 1993 (the most recent year for which comparative tables are
available), LOV ranked 50th in terms of total life premiums and annuity premiums
written. In terms of total ordinary life insurance in force, LOV ranked 71st.

     Combined Insurance and its wholly-owned subsidiary, CLICNY (which operates
exclusively in the state of New York) market primarily whole life products
through direct sales career agents in the United States.  Unit-linked products
are sold in the United Kingdom by Combined Life Assurance Company Limited, an
indirect, wholly owned subsidiary of the Registrant.  Life insurance business is
conducted in 49 states, Canada, the United Kingdom, Ireland, Germany, Australia
and New Zealand, by the Registrant's life insurance subsidiaries.  Combined
Insurance ranked among the top 100 life insurance companies in the United States
in terms of total life premiums in 1993.

     Union Fidelity focuses on third-party and affinity clients in marketing
life products, while the Group Division of Combined Insurance concentrates on
the small-employer group market offering products underwritten by Combined
Insurance.


(3) ACCIDENT AND HEALTH INSURANCE

     Combined Insurance, CLICNY, Union Fidelity, Ryan Insurance Group, Inc.
("Ryan"), Globe, and LOV.


     Through its various operating subsidiaries, the Registrant's accident and
health operations serve individuals, businesses, affinity groups and
associations in North America, Europe and the Pacific.  The accident and health
distribution network encompasses the agents of Combined Insurance, the direct-
response marketing capabilities of Union Fidelity, the agents and brokers of the
Group Division of Combined Insurance, and the automobile dealers and financial
institutions that market the products of Ryan.

     Combined Insurance, the Registrant's principal accident and health insurer,
has a direct sales force of more than 9,000 career agents calling on individuals
to sell a broad spectrum of accident and health products.  It is one of the few
companies with agents that call on customers every six months to renew and to
sell additional coverage.  Combined Insurance offers a wide range of accident
only and sickness only insurance products including short term disability,
cancer aid, Medicare supplement and disability income coverage.  Combined
Insurance's products are primarily fixed indemnity disability based, thereby not
subject to exposure to escalating medical costs.  Combined Insurance offers a
simplified accident and sickness long-term disability policy.   In 1993,
Combined Insurance was ranked among the top 10 companies in the United States
in terms of individual non-cancelable and guaranteed renewable accident and
health insurance premiums written and ranked 24th among all United States
companies in terms of total accident and health insurance premiums written.

     Operating in the United States in the highly competitive direct response
marketing segment of the  industry, Union Fidelity and the Group Division of
Combined Insurance serve different markets with different products.  Through
emphasis on service to sponsored and affiliated groups, Union Fidelity continues
to capture a stable share of the direct response market.

                                       5
<PAGE>
 
     The Group Division of Combined Insurance operates in the small-group
market, with life, long-and short-term disability, and dental insurance products
sold through managing general agents, brokers and LOV's career agent system and
agents of endorsed companies.  The group life and disability products are
underwritten by Combined Insurance and administered through the Trevose,
Pennsylvania facility.  These products are generally targeted at businesses with
fewer than 500 lives.  In particular, the Group Division of Combined Insurance
offers a portfolio of products designed for small companies desiring a flexible
benefits package for employees.

     Ryan (with policies underwritten by Globe and Union Fidelity) is the
largest independent marketer of credit life and disability products sold through
automobile dealers.  Union Fidelity sells short and long-term credit related
insurance products to qualified borrowers from financial institutions and
mortgage companies through a captive sales force and select brokers and general
agents.  In terms of direct premiums written with respect to credit life
insurance, Globe ranked third among all companies in 1993. In January 1995,
Globe merged with Combined Insurance.  Ryan subsidiaries operate in a highly
competitive industry, competing against numerous insurers and insurance agents
engaged in selling credit life and disability insurance, including some which
also provide finance and consulting services to automobile dealers.  Ryan also
is in direct competition with lending institutions which operate on a national
basis, some of which have working arrangements with insurance companies writing
credit insurance. Substantially all of the credit insurance sold by Ryan
subsidiaries is generated through dealers or financial institutions who have no
legal obligation or commitment to continue as agents for Ryan and are free to
terminate such relationships and act as agents for, and place insurance with,
Ryan's competitors.


(4) SPECIALTY PROPERTY AND CASUALTY INSURANCE
 

     Ryan, Virginia Surety Company, Inc. ("VSC"), London General Insurance
Company, Ltd. ("London General"), and Dearborn Insurance Company ("Dearborn").


     The Registrant's specialty property and casualty insurance business,
conducted by subsidiaries VSC, Dearborn & London General, has traditionally been
composed primarily of extended warranty insurance products, professional
liability insurance coverages, workers' compensation and specialty financial
institution coverages.  During 1994, VSC continued its withdrawal from the
direct risk-taking and underwriting of certain lines of property and casualty
business except extended warranty and the reinsurance of various liability
programs.  VSC and London General continue to be the largest independent
providers of automobile extended warranties worldwide.  Ryan's automobile
warranty products are sold in the United Kingdom, Ireland, France, the
Netherlands, Belgium and Spain.

     During 1994, Aon Warranty Group was created to handle certain extended
warranty products on automobiles, electronic goods, personal computers and
appliances.  In addition, the company acquired Independent Dealer Services Inc.
(IDS) of St. Louis, a major extended warranty marketing and administration
company for electronic goods, personal computers and appliances.


LICENSING AND REGULATION

     Insurance companies must comply with laws and regulations of the
jurisdictions in which they do business. These laws and regulations are designed
to ensure financial solvency of insurance companies and to require fair and
adequate service and treatment for policyholders. They are enforced by the
states in the United States, by industry self-regulating agencies in the United
Kingdom, and by various regulatory agencies in other countries through the
granting and revoking of licenses to do business, licensing of agents,
monitoring of trade practices, policy form approval, minimum loss ratio
requirements, limits on premium and commission rates, and minimum reserve and
capital requirements. Compliance is monitored by the state insurance departments
through periodic regulatory reporting procedures and periodic

                                       6
<PAGE>
 
examinations. The quarterly and annual financial reports to the regulators in
the United States utilize accounting principles which are different from the
generally accepted accounting principles used in stockholders' reports. The
statutory accounting principles, in keeping with the intent to assure the
protection of policyholders, are based, in general, on a liquidation concept
while generally accepted accounting principles are based on a going concern
concept.

     The state insurance regulators are members of the National Association of
Insurance Commissioners ("NAIC"). This Association seeks to promote uniformity
of and to enhance the state regulation of insurance. Both the NAIC and the
individual states have significantly increased their focus on the solvency of
insurance companies. This focus is reflected in additional regulatory oversight
by the states and emphasis on the enactment or adoption of a series of NAIC
model laws and regulations designed to promote solvency. The increase in any
solvency related oversight by the states will not have any significant impact on
the insurance business of the Registrant.

     In addition, the NAIC has developed a formula for analyzing insurers called
risk based capital ("RBC"). RBC is intended to establish "minimum" capital
threshold levels that vary with the size and mix of business of a company. It is
designed to identify companies with the capital levels that may require
regulatory attention. RBC does not have any significant impact on the insurance
business of the Registrant.

     Insurance companies are generally not subject to any federal regulation of
their insurance business because of the existence of a federal law commonly
known as the McCarran-Ferguson Act. McCarran-Ferguson provides the insurance
industry with immunity from certain aspects of the federal anti-trust law and
exempts the business of insurance from federal regulation. In the past several
years there have been a number of recommendations that McCarran-Ferguson be
repealed entirely or modified to remove the industry's anti-trust exemption and
subject it to federal regulation. If McCarran-Ferguson were to be repealed or
modified, state regulation of the insurance business would continue. The result
could be an additional layer of federal regulation. The Registrant expects that
any repeal of anti-trust exemptions available to insurers under the McCarran-
Ferguson Act would not have a significant impact on its operations.

     The state insurance holding company laws require prior notice to and
approval of the domestic state insurance department of intracorporate transfers
of assets within the holding company structure, including the payment of
dividends by insurance company subsidiaries. In addition, sales of credit
insurance by Ryan's agents and premium finance loans by Cananwill, Inc., an
indirect wholly-owned subsidiary of the Registrant, are subject to one or more
of truth-in-lending and credit regulations, insurance premium finance acts,
retail installment sales acts and other similar consumer legislation. Failure to
comply with such laws or regulations can result in the temporary suspension or
permanent loss of the right to engage in business in a particular jurisdiction
as well as other penalties.

     Regulatory authorities in the states in which the operating subsidiaries of
RHH Group conduct business may require individual or company licensing to act as
brokers, agents, third party administrators, managing general agents,
reinsurance intermediaries or adjusters. Under the laws of most states,
regulatory authorities have relatively broad discretion with respect to
granting, renewing and revoking brokers' and agents' licenses to transact
business in the state. The manner of operating in particular states may vary
according to the licensing requirements of the particular state, which may
require, among other things, that a firm operate in the state through a local
corporation. In a few states, licenses are issued only to individual residents
or locally-owned business entities. In such cases, RHH Group subsidiaries have
arrangements with residents or business entities licensed to act in the state.

     If their sales activities so require, employees of some of the Registrants
are registered with one of the Registrant's three broker-dealer subsidiaries. 
These broker-dealers and employees registered therewith are subject to the 
Securities Exchange Act of 1934, to rules and regulations promulgated thereunder
by the SEC and to state securities laws and regulations.

     There continues to be activity in the area of health care reform at the
state levels in the United States. Numerous states have had legislation
introduced to reform the health care system and such legislation has passed in
several states. While it is impossible to forecast the precise nature of future
state health care changes, the Registrant does not expect a major impact on its
operations because of the 

                                       7
<PAGE>
 
supplemental nature of most of the policies issued by its insurance subsidiaries
and because the coverages are primarily purchased to provide financial
protection through loss of time or disability benefits.  If health care reform
does not provide for a significant role for insurance companies currently
writing primary medical coverage, the Registrant expects that some of those
companies would increase their participation in other segments of the accident
and health insurance business, perhaps heightening the competition with Combined
Insurance.  Combined Insurance and its subsidiaries currently operate
successfully in several foreign countries which have national health plans in
effect.


MORTGAGE LOAN AND REAL ESTATE INVESTMENTS

     Mortgage loans and real estate investments held by the Registrants'
subsidiaries at December 31, 1994 were $567.5 million and $35.6 million,
respectively.  Commercial mortgage loans represent over 98% of total mortgage
loans at December 31, 1994.  Mortgage loans and real estate in the South
Atlantic region totalled $307.6 million and $26.8 million, respectively, at
December 31, 1994.  The five states carrying the highest concentrations of these
mortgage loans and real estate investments are listed below by each category.

</TABLE>

     Among these product types, those that are investment type contracts (as
defined by Statement of Financial Accounting Standards No. 97) are annuities
(approximately 87% are single premium deferred annuities) and guaranteed
investment contracts.  Significant terms and conditions of these contracts are
described below.


                                       8
<PAGE>

     SINGLE PREMIUM DEFERRED ANNUITIES (SPDAS):   The Registrant's insurance
subsidiaries had approximately $2 billion of SPDA reserves in force at December
31, 1994.  SPDAs are single premium accumulation vehicles with one, three or
five year interest rate guarantees, after which declared one year guaranteed
renewal rates are set based on prevailing economic conditions.  There is a
minimum guaranteed interest rate of 4% on most policies.  Policies contain
decreasing surrender charges for either a five or seven year period, and contain
several guaranteed income options at maturity.  Approximately 13% of the in
force SPDA policyholder funds have a bailout option where, if the declared
renewal interest rate is less than the initial rate, the policyowner may
surrender the policy without a surrender charge.  The policyowner has a 30 to 
60-day time period in which to exercise this option.

     GUARANTEED INVESTMENT CONTRACTS (GICS):  The Registrant's insurance
subsidiaries had approximately $1.6 billion in GIC contracts outstanding at
December 31, 1994.  Of these, 65% are fixed rate contracts originally written
with a maturity from two to six years.  The average maturity of the fixed rate
GIC pool was 2.4 years at December 31, 1994.  Most of these contracts either
cannot be liquidated prior to maturity, or if they can be liquidated by the
contractholder, they are subject to a market value adjustment calculated to
provide a significant penalty to the contractholder.  The remaining 35% of the
GICs are variable rate contracts which have rates that float monthly based on an
index relating to money market yields.  These contracts have no fixed maturities
but may be liquidated in seven days to one year, depending on the contract, at
the contractholder's request.  The  Registrant's insurance subsidiaries may, at
their option, change the index, but if they do so, the contractholder would have
a right to liquidate the contract.

     Most of the GICs are benefit sensitive to varying degrees.  As of December
31, 1994, most GIC contracts were for the benefit of qualified retirement plans.
The terms of these investment type contracts are typical of similar products
sold by competitors.


CLIENTELE

     No significant part of the Registrant's or its subsidiaries' business is
dependent upon a single client or on a few clients, the loss of any one of which
would have a material adverse effect on the Registrant.


EMPLOYEES

     The Registrant's subsidiaries, at the end of 1994, had more than 18,000
salaried and hourly employees and approximately 9,000 sales representatives who
are generally compensated wholly or primarily by commission.


ITEM 2.  PROPERTIES.

     The Registrants' subsidiaries own and occupy office buildings in seven
states, Puerto Rico and certain foreign countries, and lease office space
elsewhere in the United States and in various foreign cities.  Loss of the use
of any owned or leased property, while potentially disruptive, would have no
material impact on the Registrant.


ITEM 3.  LEGAL PROCEEDINGS.

     The Registrant hereby incorporates by reference note 11 of the Notes to
Consolidated Financial Statements on page 48 of the Annual Report.



ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     None.

     policyholders of insurance companies under regulatory supervision for the
     years ended December 31, 1994, 1993 and 1992 were $6.9 million, $5.8
     million and $3.6 million, respectively. In addition, Aon's reserve for the
     recognition of probable assessments for known industry insolvencies was

     transfer to the parent company are limited to the amounts that the
     insurance subsidiaries' statutory net assets exceed minimum statutory
     capital requirements; however, payment of the amounts as dividends in
     excess of $286 million may be subject to approval by regulatory
     authorities.

                             1994 RESTATEMENT OF 

                               AON SAVINGS PLAN

            (Previously known as Combined International Corporation
                        Staff Employees' Savings Plan)


       WHEREAS, Rollins Burdick Hunter Co. entered into an agreement
establishing a profit- sharing plan and a trust pursuant to the plan for the
benefit of its employees and the employees of its subsidiaries which adopted the
plan, which agreement was known as the Rollins Burdick Hunter Co. Savings and
Investment Plan;

       WHEREAS, effective July 1, 1984, Combined International Corporation, the
parent corporation of Rollins Burdick Hunter Co., adopted this profit-sharing
Plan and Trust agreement for the Staff Employees of Combined and of its various
other subsidiaries, amended and restated the Plan and Trust agreement, changed
the name of the Plan and Trust agreement to the Combined International
Corporation Staff Employees' Savings Plan, and made Combined the sponsor of the
Plan and Trust agreement;

       WHEREAS, pursuant to said 1984 Restatement, assets and liabilities under
various plans within the Combined group for participants therein were
transferred to this Plan pursuant to IRC Sections 401(a)(12) and 414(l) and
Section 208 of ERISA, and pursuant to the provisions of such plans; and assets
and liabilities under various plans within the Aon group were likewise
transferred to the Plan pursuant the 1989 Restatement and subsequent amendments
in similar fashion;

       WHEREAS, the Plan previously had been set forth in an instrument dated
July 1, 1984, and was amended five times after that last restatement thereof, on
July 20, 1984; December 13, 1984; again on December 13, 1984; November 15, 1985;
and on November

                                                                  Page 8 of 92
 
20, 1987; and whereas the Plan was restated by a 1987 Restatement thereof on
November 20, 1987 which itself was amended one time on April 15, 1988;

       WHEREAS, the Plan was again restated effective January 1, 1989 ("Second
Amendment to and 1989 Restatement of Aon Savings Plan") in order to comply with
the Tax Reform Act of 1986 and other later changes in the law and to change the
name of the Plan and Trust agreement to the Aon Savings Plan;

       WHEREAS, AON CORPORATION (sometimes referred to herein as "Aon") now
wishes to amend and again restate the Plan and Trust agreement for the purpose
of complying with the Omnibus Budget Reconciliation Act of 1993 and other
changes in the law and to make certain other desirable changes therein,
including changes necessary for the Plan to constitute an ERISA 404(c) plan
wherein the fiduciaries may be relieved of liability for any losses which are
the direct and necessary result of investment instructions given by participants

                                                                  Page 9 of 92
 
                        SECTION 1 - DEFINITION OF TERMS


       Unless the context shall otherwise clearly indicate, the following terms
shall be construed as hereinafter defined:


 1.01  THE TERM "AFFILIATE" shall refer to a substantially owned subsidiary or
       sub-subsidiary of Aon that has not adopted the Plan herein set forth.

 1.02  THE TERM "ANNIVERSARY DATE" shall refer to the last day of each Plan Year
       during which this Agreement shall be in force and effect.

 1.03  THE TERM "BASIC PAY DEFERRAL AMOUNT" shall refer to the amount by which a
       Participant has elected to have his Compensation adjusted under Section
       3.03.

 1.04  THE TERM "BENEFICIARIES" shall refer to persons designated by the
       Participant to receive his share of any property of the Trust in case of
       the Participant's death.

 1.05  THE TERM "BOARD" shall refer to the Board of Directors of Aon or any
       committee of the Board of Directors delegated authority to act for the
       whole Board in respect of matters relating to the Plan.

 1.06  THE TERM "COMMITTEE" shall refer to the Committee appointed by the Board
       pursuant to Section 7.01. The Committee is designated as the
       administrator, plan administrator, and named fiduciary with respect to
       the administration of the Plan (but not with respect to the control,
       management and investment of the assets of the trust) for the purposes of
       ERISA.

 1.07  THE TERM "COMPANY" as used herein shall refer to Aon Corporation
       (hereinafter referred to as "Aon" when referring only to Aon Corporation)
       when applying the provisions of this Trust as its profit sharing plan for
       its Employees.  It shall refer to each "Subsidiary" when applying the
       provisions of this Trust as the profit-sharing plan for the Employees of
       such Subsidiary.   The term "Companies" as used herein shall refer
       collectively to Aon and all Subsidiaries and shall be applied as though
       all of such Companies constituted a single employer.

 1.08  THE TERM "COMPENSATION" shall mean the following types of earnings paid
       to an Employee for his service on behalf of the Company subsequent to the
       date he becomes a Participant, determined before excluding any reduction
       described in Sections 3.03 and 3.04 or for cafeteria plans under Section
       125 of the IRC, but excluding any such amounts paid to him in respect to
       employment during which he is not permanently employed within the United
       States or its possessions as set forth in Section 2.01(b):

       (a) salary and fixed-based compensation including compensation for
           overtime;

                                                                  Exhibit 10(f)
                                                                  Page 10 of 92
 
       (b) bonuses paid pursuant to periodic individual performance appraisals
           and formal contractual bonus programs, but excluding other bonus and
           miscellaneous income; and

       (c) net commission, renewal and override compensation (but excluding
           deferred commission payments).

       In addition to other applicable limitations set forth in the Plan, and
       notwithstanding any other provision of the Plan to the contrary, for Plan
       Years beginning on or after January 1, 1994, the annual Compensation of
       each Employee taken into account under the Plan shall not exceed the OBRA
       '93 annual compensation limit. The OBRA '93 annual compensation limit is
       $150,000, as adjusted by the commissioner of the Internal Revenue Service
       for increases in the cost of living in accordance with Section
       401(a)(17)(B) of the IRC. The cost-of-living adjustment in effect for a
       calendar year applies to any period, not exceeding 12 months, over which
       compensation is determined (determination period) beginning in such
       calendar year. If a determination period consists of fewer than 12
       months, the OBRA '93 annual compensation limit will be multiplied by a
       fraction, the numerator of which is the number of months in the
       determination period, and the denominator of which is 12.

       For plan years beginning on or after January 1, 1994, any reference in
       this Plan to the limitation under section 401(a)(17) of the IRC shall
       mean the OBRA '93 annual compensation limit set forth in this provision.

       If Compensation for any prior determination period is taken into account
       in determining an employee's benefits accruing in the current Plan Year,
       the Compensation for that prior determination period is subject to the
       OBRA '93 annual compensation limit in effect for that prior determination
       period. For this purpose, for determination periods beginning before the
       first day of the first plan year beginning on or after January 1, 1994,
       the OBRA '93 annual compensation limit is $150,000.

       In determining Compensation the rules of Section 1.12(d) shall apply
       except the term "family" shall be limited to the Employee's spouse and to
       any lineal descendants of the Employee who have not attained age 19
       before the close of the year.

 1.09  THE "EFFECTIVE DATE" of this Plan as restated shall be January 1, 1994 .

 1.10  THE TERM "EMPLOYEE" shall refer to all employees of the Companies, except
       those who are included in a unit of employees covered by a collective
       bargaining agreement between employee representatives and one or more
       employers, if retirement benefits were the subject of good faith
       bargaining between such employee representatives and such employer or
       employers.

                                                                  Page 11 of 92

 
 1.11  THE TERM "ERISA" refers to the Employee Retirement Income Security Act of
       1974, as from time to time amended.

 1.12  THE TERM "HIGHLY COMPENSATED EMPLOYEE" shall include an employee who
       received compensation in excess of $75,000, received compensation in
       excess of $50,000 and was in the top-paid group, or was an officer and
       received compensation greater than $45,000 (all amounts as adjusted for
       increases in the cost of living per Section 14.6), either (i) in the
       current year while a member of the 100 employees paid the greatest
       compensation or (ii) in the preceding year.  The term "compensation"
       means compensation under Section 14.06, and shall include reductions
       described in Sections 3.03 and 3.04 or for cafeteria plans under Section
       125 of the IRC.  The following rules shall apply.

       (a) Five-percent owner.  Such term shall also include an employee who was
           a five-percent owner (as defined at Section 16.02(b)) at any time
           during either the preceding year or the current year.

       (b) Top-paid group.  The "top-paid group" is the group consisting of the
           top 20 percent of employees ranked on the basis of compensation paid
           during the year. For purposes of determining the number of employees
           in the top-paid group (but not for purposes of identifying the
           particular employees therein), or the number of officers taken into
           account under Subsection (c), below, there shall be excluded those
           employees who have not completed six months of service; employees who
           normally work either less than 17 1/2 hours per week or not more than
           six months during any year; employees who have not attained age 21;
           and except to the extent provided in regulations, employees included
           in a unit of employees covered by a collective bargaining agreement.

       (c) Officers.  The highest paid officer shall always be treated as a
           Highly Compensated Employee; otherwise the number of officers so
           treated shall not exceed the lesser of (i) 50 employees or (ii) the
           greater of three employees or 10 percent of the employees.

       (d) Family members.  Any individual who is a member of the family (i.e.,
           the spouse, and lineal ascendants or descendants and their spouses)
           of a Highly Compensated Employee who is either a five-percent owner
           or one of the ten most highly compensated employees shall not be
           considered a separate employee and his compensation (and any
           applicable contribution or benefit on behalf of such individual)
           shall be treated as if it were paid to (or on behalf of) such Highly
           Compensated Employee. This rule shall apply in determining the
           compensation of (or any contributions or benefits on behalf of) any
           employee for purposes of any Section of the IRC with respect to which
           a Highly Compensated Employee is defined by reference to IRC Section
           414(q) (the provisions of which are set forth in this Section),
           except as provided in regulations and except in determining the
           portion of the

                                                                   Page 12 of 92


           compensation of a Participant which is under the integration level
           for purposes of IRC Section 401(l).

      (e)  Former employees.  A former employee shall be treated as a Highly
           Compensated Employee if he was a Highly Compensated Employee either
           (i) when he separated from service or (ii) at any time after
           attaining age 55.

      (f)  Nonresident Aliens.  For purposes of this Section, employees who are
           nonresident aliens and who receive no earned income (within the
           meaning of Section 911(d)(2) of the IRC ) from the Company which
           constitutes income from sources within the United States shall not be
           treated as employees.

      (g)  Simplified Method for Determining Highly Compensated Employees.   If
           an election by the Company under this subsection applies to any year,
           in determining whether an employee is a Highly Compensated Employee
           for such year, the first sentence of this Section shall be applied by
           substituting "$50,000" for "$75,000," and the $50,000 test for the
           top-paid group shall not apply.  Such election shall not apply to any
           year unless at all times during such year, the Company maintained
           significant business activities (and employed employees) in at least
           2 significantly separate geographic areas, and the Company satisfies
           such other conditions as the Secretary of the Treasury may prescribe.

      (h)  Coordination with Other Provisions.  Section 14.02 shall be applied
           before the application of this Section 1.12.


1.13  THE TERM "HOURS OF SERVICE" shall refer to the hours for which an Employee
      is directly or indirectly paid or entitled to payment, for the performance
      of duties or for a period of time during which no duties are performed
      (irrespective of whether the employment relationship has terminated)
      during the applicable computation period and such hours shall include any
      hours for which back pay, irrespective of mitigation of damages, has
      either been awarded or agreed to; provided, however, no more than 501
      Hours of Service shall be credited on account of any single continuous
      period during which an Employee performs no duties (whether or not such
      period occurs in a single computation period).  An Employee who enters
      military service and again becomes actively employed upon separation from
      such service shall be credited with Hours of Service in respect to his
      period of military service only to the extent and for the purposes
      required by federal law governing veterans' reemployment rights.  Hours
      shall not be credited for payments made or due under a plan maintained
      solely for the purpose of complying with applicable workmen's
      compensation, unemployment compensation, or disability insurance laws, or
      for a payment which solely reimburses an Employee for medical or medically
      related expenses incurred by the Employee.  In those instances where
      payroll or other Company records do not reflect the actual number of hours
      worked by an Employee, such Employee shall be credited with 45 Hours of
      Service for each calendar week that he would be required to be

                                                                   Page 13 of 92


      credited with at least one Hour of Service under the preceding portion of
      this Section.  This Section shall be applied, in respect to payments for
      reasons other than the performance of duties and in respect to crediting
      of Hours of Service to a particular computation period, in accordance with
      the rules set forth in Labor Department Regulations Section 2530.200b-2(b)
      and (c), which are incorporated herein by reference.

1.14  THE TERM "INSTITUTIONAL TRUSTEE" shall refer to the bank, or other
      corporate trustee, duly appointed pursuant to Sections 5.05 and 6.01 of

      and investment of the assets of the Aon Stock Fund.

1.17  THE TERM "LEASED EMPLOYEE" shall refer to an individual, other than an
      employee of the Employer or an affiliated employer (the "recipient
      employer"), who, pursuant to an agreement between the recipient employer
      and any other person (the "leasing organization") has performed services
      for the recipient employer (or the recipient employer and related persons
      determined in accordance with Section 414(n) of the IRC) on a
      substantially full-time basis for a period of at least one year, and such
      services are of a type historically performed by employment in the
      business field of the recipient employer.  Contributions or benefits
      provided a Leased Employee by the leasing organization which are
      attributable to services performed for the recipient employer shall be
      treated as provided by the recipient employer.  A leased employee shall
      not be considered an employee of the recipient employer if:

      (a)  such individual is covered by a money purchase pension plan
           providing:

           (i)    a nonintegrated employer contribution rate of at least ten
                  percent of compensation, but including amounts contributed
                  pursuant to a salary reduction agreement which are excludible
                  from the employee's gross income under Section 125, 402(e)(3),
                  402(h), or 403(b) of the IRC,

           (ii)   immediate participation, and

           (iii)  full and immediate vesting; and

                                                                   Page 14 of 92

      which there was such an absence.  "Maternity or Paternity Leave" shall

      deemed to be a Participant.

      instrument, as the same may be amended from time to time.

           is reemployed before he has incurred five 1-Year Breaks in Service,
           the period commencing with the date his employment terminated and
           ending with his reemployment date shall be counted as uninterrupted

           pursuant to Section 2.01; provided, that not more than 12 months of

           determining his vested interest pursuant to Section 9.02.

      (a)  He must have completed one year of Service and attained the age of
           21.  In determining whether or not an Employee has completed the
           required year of Service, there shall be disregarded, except as
           provided in the next sentence, Service prior to any break in Service
           equal to or more than the greater of five 1-Year Breaks in Service or
           his prior completed years of Service.  Once an Employee has completed
           his required year of Service, subsequent breaks in Service shall not
           affect the fact that this requirement has been completed;

      (b)  He must be employed within the United States or its possessions on a
           permanent basis as determined under Section 2.05; and

      (c)  He must sign and deliver to the Committee an Agreement of
           Participation, Designation of Beneficiary and Compensation Adjustment
           Election in such form as may from time to time be prescribed by the
           Committee.

      The Committee shall notify all Employees who are eligible to participate
      in this Trust and shall provide them with an Agreement of Participation,
      Designation of Beneficiary and Compensation Adjustment Election.  Any
      Employee who does not elect to become a Participant as of the first date
      on which he would otherwise be eligible, may become a Participant as of
      the first day of any succeeding pay period if he is still eligible and
      upon compliance with the provisions of this Section 2.01.  Leased
      Employees shall not be eligible to participate in the Plan.

2.02  TERMINATION OF EMPLOYMENT.  Any Participant whose employment with the
      Companies is terminated for any reason whatsoever, shall cease to be
      eligible to participate hereunder, except to the extent he or his
      beneficiary shall have the right to receive payments from his individual
      accounts as provided in Section 8 hereof.  Except as provided in Section
      8.04, any Participant whose employment with the Companies is terminated
      shall, in the event of his later reemployment, become a Participant on the
      first day of the first pay period following his signing and delivery of
      the documents referred to in Section 2.01(c).  If a reemployed Employee,
      by such action, again becomes a Participant in the Plan Year his
      employment terminated, and he remains a Participant through the last day
      of that Plan Year, he shall be entitled to share in the Companies'
      contribution, and in the forfeitures, for that Plan Year in accordance
      with Section 4.01(a).  Any person who has ceased to be a Participant
      hereunder by virtue of termination of his employment and for whom the
      Trustee continues to hold a portion of his Participant's Basic
      Contribution Account, Participant's Supplemental Contribution Account,
      Participant's Voluntary Contribution Account or Company Contribution

      Account shall continue to share in net earnings and valuation adjustments
      (as provided in Section 8.08 hereof) as though he were a Participant.

2.03  LEAVE OF ABSENCE.  Any Participant obtaining a leave of absence from the
      Company because of illness, disability (except permanent disability,
      provision for which is made in Section 8.02 hereof) or national emergency
      requiring governmental, military, or naval service subsequent to the
      execution of this agreement or for any other reason, shall continue to
      participate in this Trust and shall not be deemed to have his employment
      terminated.  The Companies agree to adopt a uniform policy with reference
      to the granting of leaves of absence.  Such policy shall be applied
      without individual selection or discrimination in all cases involving the
      same, or substantially the same, facts.  The Companies shall provide the
      Committee with all information with reference to leaves of absence.  The
      determination made by or caused to be made by the Companies shall be
      conclusive and binding upon all persons having any interest in the Trust.

2.04  TRANSFER TO AN AFFILIATE.  If a Participant is transferred to the
      employment of an Affiliate, he shall be deemed to be on leave of absence
      during such time as he is an Employee of the Affiliate.

2.05  TRANSFER TO A FOREIGN COUNTRY.  The determination of when an Employee is
      employed within the United States on a permanent basis, when a transfer
      from the United States is or becomes permanent, and when a transfer to or
      from the United States is temporary, shall be made by the Company and such
      determination shall be conclusive and binding on all persons having any
      interest in the Trust.  If he is transferred from the United States on a
      temporary basis, he shall be deemed to continue as being employed within
      the United States on a permanent basis until such time as his transfer
      becomes permanent.

2.06  EMPLOYMENT IN BARGAINING UNIT.  An individual in a bargaining unit who is
      not deemed to be an Employee by reason of Section 1.10 shall not be
      eligible to participate hereunder and shall not be entitled to make
      contributions hereunder.  Notwithstanding the foregoing, his Service in
      such bargaining unit shall be counted for the purpose of determining his
      eligibility to participate pursuant to Section 2.01, and if a Participant
      becomes ineligible to participate hereunder by reason of employment in
      such bargaining unit, his Service in such bargaining unit shall be 
      counted for the purpose of determining his nonforfeitable interest under
      Section 9.

                           SECTION 3 - CONTRIBUTIONS



 3.01  CONTRIBUTIONS BY COMPANIES.

       (a) Aggregate Contribution. For the Plan Year ending December 31, 1989,
           and for each Plan Year thereafter, the Companies, in total, shall pay
           to the Trustee the amount set forth below. Except for contributions
           under Items (i) and (ii), below, the payment shall be limited to the
           total current pretax earnings or profits of the Companies and
           Affiliates for that year (as shown on the Consolidated Statements of
           Income for Aon and its subsidiaries reported in the Annual Report to
           Shareholders of Aon as certified by a firm of Independent Public
           Accountants). The preceding two sentences shall be subject to what is
           stated in Section 3.01(c). The aggregate contribution of the
           Companies for Staff Employees shall be an amount equal to the sum of
           (i), (ii), and (iii) below.

           (i)  An amount equal to the Basic Pay Deferral Amounts applicable to
                Participants employed by the Company during such Plan Year.

           (ii) An amount equal to the Supplemental Pay Deferral Amounts
                applicable to Participants employed by the Company during such
                Plan Year.

           (iii)An additional amount equal to one hundred percent (100%) of the
                Basic Pay Deferral Amounts applicable to Participants who on the
                last day of such Plan Year are employed by the Company and have
                not completely discontinued their Basic Pay Deferral Amounts;
                provided, that such contribution shall be made only on Basic Pay
                Deferral Amounts of up to three percent (3%) of a Participant's
                Compensation and shall not be made on additional Basic Pay
                Deferral Amounts.

       (b) Allocation and Possible Reduction of Aggregate Contribution. Each of
           the Companies' share of the aggregate contribution described in
           Section 3.01(a) shall be equal to the amount of such contribution as
           will be allocated to the individual accounts of Participants who are
           employed by it pursuant to Section 4.01(a). If, during any Plan Year,
           any Participant is employed by more than one Company that has adopted
           this Plan, the amount allocable to such Participant's account may be
           allocated among such Companies in the proportion of Basic Pay
           Deferral Amounts paid by each during the Plan Year in respect to
           which the contribution is made.

       (c) Maximum Contribution of Each Company. Except for contributions of Pay
           Deferral Amounts under Sections 3.01(a)(i) and (ii), each Company
           shall contribute no more than an amount equal to the lesser of its
           current or

                                      49

                                                                   Page 19 of 92

          accumulated earnings or profits or the maximum amount deductible under
          the IRC for the year for which the contribution is made.  If, because
          of the aforesaid limitation, any Company is unable to make all or any
          part of the contribution that would otherwise be due from it, the
          amounts that would otherwise be allocated to the Participants (or the
          affected group of Participants) employed by such Company, pursuant to
          Section 4.01(a) hereof, shall be proportionately reduced; provided
          that an additional contribution may be made by any Company to the
          extent permitted by IRC Section 404(a)(3)(B).

 3.02  DATE OF CONTRIBUTION.  For the purposes of this Agreement, the date of
       any Company contributions under Section 3.01(a)(i) or (ii) shall be as of
       the last day of each month and they shall be remitted to the Trustees not
       less frequently than quarterly. The date of any Company contribution
       under Section 3.01(a)(iii) will be deemed to be the last day of the Plan
       Year for which the contribution is made, even though received by the
       Trustee at a later or earlier date.

 3.03  BASIC PAY DEFERRAL AMOUNT.  Except as provided in Section 8.04:

       (a) Nonhighly Compensated Participants.  Each Participant who was not a
           Highly Compensated Employee as of the immediately preceding
           Anniversary Date may elect to have his Compensation reduced by any
           whole percentage of his Compensation (as defined in Section 1.08)
           from two percent (2%) through ten percent (10%).

       (b) Highly Compensated Participants. Each Participant who was a Highly
           Compensated Employee as of the immediately preceding Anniversary Date
           may elect to have his Compensation reduced by any whole percentage of
           his Compensation (as defined in Section 1.08) from two percent (2%)
           through six percent (6%).

       The amount of such reduction in a Participant's Compensation is sometimes
       referred to herein as the "Basic Pay Deferral Amount."

 3.04  SUPPLEMENTAL PAY DEFERRAL AMOUNT.  Each Participant who has elected a ten
       percent (10%) reduction under Section 3.03(a) or a six percent (6%)
       reduction under Section 3.03(b) may elect to have his Compensation
       further reduced as provided in Section 1.25.  The amount of such
       reduction is sometimes herein referred to as the Supplemental Pay
       Deferral Amount.

 3.05  VOLUNTARY CONTRIBUTIONS BY PARTICIPANTS.  Except as provided in Section
       8.04, each Participant may, at his election, contribute to the Trustee
       for each Plan Year, up to nine percent (9%) of his Compensation as
       defined at Section 1.08 for the Plan Year.  The contribution which a
       Participant has elected to make shall be deducted by the Company from
       each payment of Compensation made to such Participant at the time the
       same is paid, and remitted directly by the Company

                                                                   Exhibit 10(F)
                                                                   Page 20 of 92
 
       to the Trustee on behalf of such Participant within three months after
       the deduction is made.  Contributions under this Section shall be subject
       to the following restrictions and limitations:

       (a) Change in Rate. A Participant may elect to change the rate of his
           voluntary contributions by filing a written application with the
           Committee, and such change shall be effective as soon as
           administratively convenient thereafter.

       (b) Discontinuance. A Participant may elect to discontinue making
           voluntary contributions, but in such event he may not elect to again
           make voluntary contributions in the same Plan Year.

       (c) Full Percentage. Voluntary Contributions must be expressed as a full
           percentage point of Compensation (i.e., 1%, 2%, 3%, 4%, 5%, 6%, 7%,
           8%, or 9%).

       (d) Withdrawals. A Participant may withdraw his own voluntary
           contributions, or any part thereof, but only two such withdrawals
           shall be permitted under this Section in any Plan Year. A withdrawal
           under this Section shall not be considered an Application for
           Benefits under Section 8.04, and the Company shall continue to make
           the contributions required by Section 3.01. Any withdrawal shall be
           for at least $1,000 or if less, the lesser of (1) the Participant's
           actual unwithdrawn Voluntary Contributions, (2) the balance in his
           Voluntary Contribution Account.

       (e) Discretion. Voluntary contributions on or after January 1, 1987,
           shall be allowable only at the discretion of the Board. Such
           contributions may be allowed under the rules or limitations of
           Sections 401(k) and (m) of the IRC, and may be made allowable for
           only those Participants who are not Highly Compensated Employees.
           Accordingly, the rules set forth above in this Section shall be for
           guidance only and the rules and intent of Subsections (e) through (h)
           shall be controlling.

       (f) First Withdrawals. The first withdrawals shall be made from the
           subaccount for contributions made prior to January 1, 1987, and
           earnings thereon. Such withdrawals shall be limited to the amount of
           such contributions. Upon all of such contributions having been
           withdrawn and upon the Participant becoming 100% vested in his
           Company Contribution Account, the earnings may at the discretion of
           the Committee be transferred to the Participant's Company
           Contribution Account.

       (g) Post-86 Amounts. Withdrawals shall next be made from contributions
           made on or after January 1, 1987, if any, and there shall be a
           separate sub-account for these amounts. Allocation of any withdrawal
           between contributions and earnings shall be made pursuant to IRC
           Section 72(d) and (e) as amended from time to time, and regulations
           and rulings thereunder.

                                                                   Page 21 of 92
 
       (h) Rollovers. Any separate sub-account for amounts previously rolled
           over under Section 3.10 shall be transferred to a separate sub-
           account in the Participant's Company Contribution Account and shall
           be treated as one hundred percent (100%) vested.

 3.06  RESTRICTIONS AND LIMITATIONS ON PAY DEFERRAL AMOUNTS.  Pay Deferral
       Amounts and Voluntary Contributions under Sections 3.03, 3.04 and 3.05
       shall be subject to the following restrictions and limitations:

       (a) A Participant may elect to change the rate of his Basic or
           Supplemental Pay Deferral Amounts under Sections 3.03 and 3.04. Such
           election shall become effective as soon as administratively
           convenient after receipt thereof by the Committee.

       (b) Pay Deferral Amounts must be expressed as a full percentage point of
           Compensation.

       (c) A Supplemental Pay Deferral Amount may not be in effect in respect to
           any period of time in respect to which a Basic Deferral Amount of six
           percent (6%) or more of Compensation in the case of a Highly
           Compensated Employee and ten percent (10%) or more in the case of a
           Participant who is not a Highly Compensated Employee is not in
           effect.

       (d) No Compensation reduction election under Section 3.03 or 3.04 shall
           apply to a terminated or retired Participant in respect to any
           Compensation paid to him (whether in the form of severance pay or
           otherwise) subsequent to the Valuation Date used to determine the
           balances of his separate accounts for the purpose of making the final
           distribution to him.

 3.07  ADJUSTMENTS IN PAY DEFERRAL AMOUNTS.  It is intended that the cash or
       deferred arrangement under Section 3.01(a)(i) and (ii) shall comply with
       the excess deferral limitations ($7,000 for 1987 and adjusted for cost of
       living) and the excess contribution limitations set forth in Sections
       402(g) and 401(k) of the IRC and the regulations and rulings construing
       Sections 402(g) and 401(k) of the IRC.  Accordingly, the following
       limitations are placed upon the Basic Pay Deferral Amount and
       Supplemental Pay Deferral Amount a Participant may elect under Section
       3.03 and 3.04.

       (a) Reductions During Plan Year. If it appears prior to the end of a Plan
           Year that the required limitations will not be complied with, the
           administrator may reduce the future Basic Pay Deferral Amount or the
           future Supplemental Pay Deferral Amount of any Participant (and
           therefore the amount of Compensation reduction) in accordance with
           the following rules.

           (i) Reductions shall be made first so as to avoid excess deferrals
               under Section 402(g) of the IRC. This reduction shall apply for
               the calendar

                                                                   Page 22 of 92

                year beginning January 1, 1987, and calendar years thereafter in
                respect to all Participants except as provided in (c), below.

          (ii)  Reductions shall be made next so as to avoid excess
                contributions under Section 401(k) of the IRC. This reduction
                shall apply for the Plan Year beginning January 1, 1987, and all
                Plan Years thereafter but only in respect to those Participants
                who are Highly Compensated Employees.

          (iii) Reductions under Paragraph (ii) shall first be made in all
                Supplemental Pay Deferral Amounts before any reductions are made
                in any Basic Pay Deferral Amount.

          (iv)  Reductions under Paragraph (ii) shall be made in such manner
                that no Highly Compensated Employee's Supplemental Pay Deferral
                Amount (or, if necessary, Basic Pay Deferral Amount) expressed
                as a percentage of Compensation will exceed that of any other
                Highly Compensated Employee whose Supplemental or Basic Pay
                Deferral Amount is reduced.

      (b) Reductions after End of Plan Year. If it appears after the end of a
          Plan Year that the required limitations have not been complied with,
          the administrator shall make reductions in the Basic Pay Deferral
          Amount or the Supplemental Pay Deferral Amount of any Participant in
          accordance with the following rules.

          (i)   Reductions shall first be made at least to the extent necessary
                to comply with the applicable excess deferral limitations
                ($7,000 for 1987 and adjusted for cost of living increases) and
                then to the extent necessary to comply with the excess
                contribution limitations. Any distribution made so as to comply
                with the excess deferral limitations shall continue to be
                treated, with respect to each Highly Compensated Employee, as a
                Company contribution in figuring whether the actual deferral
                percentage test at Section 3.09(b) has been met.

          (ii)  Reductions so as to avoid excess contributions under Section
                401(k) of the IRC shall be made only in respect to those
                Participants who are Highly Compensated Employees.

          (iii) Reductions under Paragraph (ii) shall first be made in all
                Supplemental Pay Deferral Amounts before any reductions are made
                to any Basic Pay Deferral Amount.

          (iv)  Reductions under Paragraph (ii) shall be made in such manner
                that no Highly Compensated Employee's Supplemental Pay Deferral

                                                                   Page 23 of 92

                percentage of Compensation will exceed that of any other Highly
                Compensated Employee whose Supplemental or Basic Pay Deferral
                Amount is reduced.

          (v)   The amount of any reduction in a Participant's Basic Pay
                Deferral Amount or Supplemental Pay Deferral Amount shall be
                distributed to the Participant, except that to the extent
                permitted in rules and regulations under the IRC, the
                Participant may be allowed or required by the administrator to
                have excess contributions (other than QMACs and QNCs, defined in
                Section 3.09 (d) below, and after adjustment for withholding
                taxes) recharacterized as employee contributions and transferred
                to the Participant's Voluntary Contribution Account. Such
                recharacterization shall be made and the Participant shall be
                properly notified thereof on or before two and one-half months
                after the close of the Plan Year.

          (vi)  The amount by which any Participant's Supplemental Pay Deferral
                Amount is reduced shall be charged against his Supplemental Pay
                Deferral Account.

          (vii) The amount by which any Participant's Basic Pay Deferral Amount
                is reduced shall be charged against his Basic Pay Deferral
                Account.

      (c) No Responsibility for Excess Deferrals. The amount of elective
          deferrals under all plans of the Company shall not exceed the amount
          of the limitation in effect under Section 402(g) of the IRC, as
          amended from time to time. Primary responsibility for avoiding excess
          deferrals under Section 402(g) of the IRC shall be upon the
          Participant and not upon the Company or the Committee. The Participant
          must notify the Committee in writing if (i) elective deferrals are
          being made on his behalf under IRC Section 402(g)(3) by any employer
          which is not within the Aon Group, or (ii) his taxable year is a year
          other than the calendar year.

 3.08 ADJUSTMENTS IN COMPANY MATCHING CONTRIBUTIONS AND IN PARTICIPANT
      CONTRIBUTIONS. It is intended that Company matching contributions under
      Section 3.01(a)(iii) and Participant contributions under Section 3.05
      shall comply with the excess aggregate contribution limitations set forth
      in Section 401(m) of the IRC and the rules and regulations construing
      Section 401(m) of the IRC. Accordingly, the following limitations are
      placed upon Company matching contributions and Participant contributions
      under Sections 3.01(a)(iii) and 3.05.

      (a) Reductions During Plan Year. If it appears prior to the end of a Plan
          Year that the contribution percentage limitation will not be complied
          with, the administrator may reduce the future matching Company
          contributions or the future Participant contributions of any
          Participant in accordance with the following rules.

                                                                   Page 24 of 92

 
            (i)    Reductions shall be made only in respect to those
                   Participants who are Highly Compensated Employees.

            (ii)   Reductions shall first be made in all Participant
                   contributions before any reductions are made in any matching
                   Company contributions, including return of Participant
                   contributions made earlier in the Plan Year.

            (iii)  Reductions shall be made in such manner that no Highly
                   Compensated Employee's percentage limitation will exceed that
                   of any other Highly Compensated Employee whose matching
                   Company contribution or Participant contribution is reduced.

       (b)  Reductions after End of Plan Year.  If it appears after the end of a
            Plan Year that the required contribution percentage limitation has
            not been complied with, or will not be complied with if any matching
            contribution otherwise required under Section 3.01(a)(iii) is made,
            the administrator shall make reductions in the matching Company
            contribution or Participant contribution of any Participant in
            accordance with the following rules.

            (i)    Reductions shall be made only in respect to those
                   Participants who are Highly Compensated Employees.

            (ii)   Reductions shall first be made at least to the extent
                   necessary to comply with the applicable contribution
                   percentage limitation.

            (iii)  Reductions shall first be made in all Participant
                   contributions before any reductions are made to any matching
                   Company contribution.

            (iv)   Reductions shall be made in such manner that no Highly
                   Compensated Employee's percentage limitation will exceed that
                   of any other Highly Compensated Employee whose matching
                   Company contribution or Participant contribution is reduced.

            (v)    The amount by which any Participant's matching Company
                   contribution is reduced shall be charged against his Company
                   Contribution Account.  The nonforfeitable vested portion, if
                   any, shall be distributed to the Participant.  The
                   forfeitable portion shall be reallocated, or, to the extent
                   not prohibited under the rules and regulations of the IRC,
                   may at the discretion of the Committee not be contributed by
                   the Company.

            (vi)   The amount by which any Participant's own contribution is
                   reduced shall be charged against his Voluntary Contribution
                   Account.

                                                                   Page 25 of 92

 
            (vii)  Forfeitures of excess aggregate contributions may not be
                   allocated to Participants whose contributions are reduced
                   under Paragraph (v) or (vi), above.

 3.09  SPECIAL RULES.  For purposes of Sections 3.07 and 3.08 the following
       special rules shall apply.

       (a)  The term "Compensation" shall mean compensation as defined under
            Section 414(s) of the IRC; provided, the applicable period for
            purposes of Section 414(s) shall be the Plan Year.  Such
            compensation shall be measured only during the portion of the Plan
            Year during which the Employee is eligible to Participate in the
            Plan and determined before excluding any reduction described in
            Sections 3.03 or 3.04, or for cafeteria plans under Section 125 of
            the IRC.  Any elective contribution must relate to compensation that
            either (i) would have been received by the Employee during the Plan
            Year but for the Employee's election to defer, or (ii) is
            attributable to services performed in the Plan Year and which would
            otherwise have been received by the Employee within two and one-half
            (2 1/2) months after the close of the Plan Year.  To the extent
            permissible under rules and regulations construing Section 414(s),
            the term shall have the same meaning as under Section 1.08.

       (b)  The actual deferral percentage of Pay Deferral Amounts, as adjusted
            under Section 3.07, of Highly Compensated Employees shall not be
            more than the larger of (i) 125% of such percentage for other
            Participants or, (ii) as the Alternative Limitation, twice such
            percentage but not more than two percentage points more, all
            calculations to be made to the nearest one-hundredth of 1% of the
            Employee's Compensation.  A similar limitation shall apply to the
            average contribution percentage of Company matching contributions
            and Participant contributions, as adjusted under Section 3.08, of
            Highly Compensated Employees.

       (c)  Any income allocable or attributable to any amounts distributed or
            reallocated under Sections 3.07 or 3.08 shall also be distributed or
            reallocated, pursuant to rules and regulations promulgated under
            Sections 401(k), 401(m) and 402(g) of the IRC.  The amount of such
            distributed income shall generally be total income for the Plan Year
            under Section 8.08 for the Participant's account, times the excess
            amount divided by the Participant's total account balance in that
            account; provided, that in the event of a loss the distribution or
            reallocation shall not be less than the amount of such excess except
            as allowed under rules and regulations of the IRC.  Income for any
            period of time after the end of the Plan Year and before the
            distribution date may be calculated as determined by the Committee,
            as determined by the Committee, under either the fractional method
            (described in the prior sentence for actual income during the Plan
            Year), under the safe harbor using 10% per calendar month of the
            prior year's income, or under any other method allowed under rules
            and regulations of the IRC.

                                                                   page 26 of 92
 
          (i)   The following rules shall be applied to prevent the multiple use
                of the Alternative Limitation (as defined Section 1.402(m)-2 of
                the regulations promulgated under the IRC) with respect to any
                plan year. If multiple use of the alternative limitation occurs,
                and the sum of the ADP and ACP of affected Highly Compensated
                Employees subject to either or both tests exceeds the aggregate
                limit, then the ACP of those Highly Compensated Employees will
                be reduced (beginning with the Highly Compensated Employee whose
                ACP is the highest) so that the limit is not exceeded. The
                amount by which each Highly Compensated Employee's contribution
                percentage amount is reduced shall be treated as an excess
                aggregate contribution. The ADP and ACP of the Highly
                Compensated Employees are determined after any correction
                required to meet the ADP and ACP tests. Multiple use of the
                alternative limitation does not occur if both the ADP and ACP of
                the eligible Highly Compensated Employees do not exceed 1.25
                multiplied by the ADP and ACP of the group of non-highly
                compensated employees.

       (d) The Company may elect, subject to the IRC rules and regulations:

          (i)   To the extent necessary in meeting the actual deferral
                percentage test under Subsection (b), above, as applied to Pay
                Deferral Amounts under Section 3.07, to elect to include
                matching Company contributions and nonelective Company
                contributions which meet the Plan distribution and 100% vesting
                rules for Pay Deferral Amounts as provided in IRC regulations
                and thus constitute qualified matching contributions ("QMACs")
                and qualified nonelective contributions ("QNCs"). Such matching
                and nonelective contributions must meet the general
                nondiscrimination requirements of the IRC under Section
                401(a)(4) as regards Highly Compensated Employees both after
                including and after excluding any QMAC or QNC portion thereof,
                and any QMAC or QNC portion may not be taken into account in
                determining whether any other contributions or benefits provided
                under the Plan generally discriminate as regards Highly
                Compensated Employees. Any QMACs so taken into account may be
                taken into account again under Paragraph (ii), below, as
                appropriate.

          (ii)  To the extent necessary in meeting the average contribution
                percentage test under Subsection (b), above as applied to
                Company matching contributions and to Participant contributions
                under Section 3.08, to include Pay Deferral Amounts, plus QNCs
                which meet the Plan distribution and 100% vesting rules for Pay
                Deferral Amounts, subject to the rules under Paragraph (i),
                above, as applicable under IRC rules and regulations.

          (iii) As permitted under Paragraphs (i) and (ii), above, to make an
                additional QNC on behalf of each Participant who is not a Highly

                                                                   Exhibit 10(f)
                                                                   page 27 of 92
 
 
                Compensated Employee. Such contribution may be, but need not be,
                a uniform percentage of Compensation for each such Participant
                and shall be allocated to his appropriate account or sub-account
                within the time period required by any applicable law or
                regulations. A Participant may not elect to receive any portion
                of such additional contribution as current Compensation. In lieu
                of making all or a portion of the additional QNC described in
                this Paragraph (iii), the Company may elect to have matching
                contributions under Section 3.01(a)(iii) on behalf of
                Participants who are not Highly Compensated Employees, be QMACs.
                Any such QNC or QMAC shall be allocated each such Participant's
                appropriate account or sub-account, and shall be separately
                accounted for.

       (e) Three correction rules shall apply as set forth below:

          (i)   The Committee may designate whether excess contributions under
                Section 3.07 or excess aggregate contributions under Section
                3.08 are attributable to Pay Deferral Amounts, QNCs, QMACs,
                Participant contributions, qualified nonelective contributions,
                or Company matching contributions. Any such ordering must be
                used consistently and shall be subject to the ordering rule of
                Paragraph (2).

          (ii)  The general rule for the order in which amounts are to be
                distributed is:

             (A)    excess deferrals under Section 402(g) of the IRC.

             (B)    excess contributions under Section 401(k) of the IRC.

             (C)    excess aggregate contributions under Section 401(m) of the
                    IRC.

          (iii) QNCs, QMACs, the recharacterization method, the corrective
                distribution method, or a combination of these methods may be
                used to avoid or correct excess contributions or excess
                aggregate contributions.

       (f) Any distribution or forfeiture under Section 3.07 or 3.08, including
           income thereon under Section 3.09(c), shall, insofar as
           administratively convenient, be made or reallocated before the close
           of the first two and one-half (2-1/2) months of the following Plan
           Year, and shall in all events be distributed or forfeited no later
           than the last day of such Plan Year. QMACs and QNCs properly taken
           into account may permit avoidance of excess contributions or excess
           aggregate contributions even if such contributions are made after the
           close of such two and one-half (2-1/2) month period.

   3.10  ROLLOVERS. Any amount that is an eligible rollover distribution within
         the meaning of Section 402(c)(4) of the Code may be contributed to this
         Plan by the Employee on or before the 60th day following the receipt by
         the Employee of such distribution from an employee's trust, annuity
         plan, individual retirement account, or individual retirement annuity
         described above. Alternatively, an eligible rollover distribution may
         be transferred at the direction of the Employee directly to the Trustee
         from any plan, account or annuity described above.

                     SECTION 4 - ALLOCATION OF TRUST FUNDS


 4.01  COMPANY CONTRIBUTION ACCOUNT AND ALLOCATION OF FORFEITURE.  The Committee
       shall maintain a separate account in the name of each Participant, to be
       known as the "Company Contribution Account", and the Committee shall post
       to such account of each Participant on whose behalf a Company
       contribution under Section 3.01(a)(iii) is made the following:

       (a) His share of additional Company contributions for the Plan Year,
           described in Section 3.01(a)(iii), plus his share of forfeitures from
           accounts of terminated Participants, which shall be allocated to the
           account of each Participant in the ratio that his Basic Pay Deferral
           Amount of up to three percent (3%) of his Compensation bears to such
           Basic Pay Deferral Amounts of all Participants employed on the last
           day of the Plan Year.

       For the purpose of applying the above formula, allocations shall be made
       as if there were no reduction in the contribution of any Company under
       Section 3.01(c). However, where for a Plan Year the contribution of any
       Company is reduced under Section 3.01(c), the Company Contribution
       Accounts of the Participants in the Service of such company involved as
       of December 31 of that year shall share in the reduction of the
       contribution of such Company on the basis of the above formula applied to
       them only.

       (b) Any additions or deductions arising out of net earnings and valuation
           adjustments resulting from the operation of Section 8.08 of this
           Agreement.

       (c) Any forfeitures chargeable to his account, interim net earnings and
           valuation adjustments resulting from the operation of Section 8.08 of
           this Trust Agreement and any withdrawals or other payments chargeable

                                                                   Page 30 of 92
 
 4.03  SUPPLEMENTAL PAY DEFERRAL ACCOUNT.  The Committee shall also maintain a
       separate account in the name of each Participant, to be known as the
       "Supplemental Pay Deferral Account", and the Committee shall post to such
       account of each Participant the following:

       (a) His share of Company contributions described in Section 3.01(a)(ii),
           which shall be equal to his Supplemental Pay Deferral Amount.

           operation of Section 8.08 of this Trust Agreement and any withdrawals
           or other payments chargeable to his account.

 4.04  VOLUNTARY CONTRIBUTION ACCOUNT.  The Committee shall also maintain an
       account in the name of each Participant to be known as the "Voluntary
       Contribution Account", which shall be divided into two sub-accounts for
       contributions and earnings thereon made (i) before and (ii) on or after
       January 1, 1987.  The Committee shall post to such account for each
       Participant the following:

       (a) All voluntary contributions made by such Participant pursuant to
           Section 3.05;

       (b) Any additions or deductions arising out of the net earnings and
           valuation adjustment resulting from the operation of Section 8.08 of

       (d) The amount from each Participant's former mandatory contribution
           account pursuant to Section 4.08.

       For the purpose of applying the above formula, allocations shall be made
       as if there were no reduction in the contribution of any Company under
       Section 3.01(c). However, where for a Plan Year the contribution of any
       Company is reduced under Section 3.01(c), the Company Contribution
       Accounts of the Participants in the Service of such Company involved as
       of December 31 of that year shall share in the reduction of the
       contribution of such Company on the basis of the above formula applied to
       them only.

 4.05  RECORDS AND ACCOUNTING.  Books of account, forms, and accounting methods
       used in the administration of the Plan shall be subject in all respects
       to the supervision of the Committee, and if at any time the Committee
       shall determine that the accounting methods are not fair and equitable to
       all Participants, the Committee shall have the right to make whatever
       adjustments are necessary in the accounting

                                                                   Page 31 of 92
 
       methods to carry out this Agreement.  In the event an erroneous amount is
       posted to a Participant's account for any year, the Committee may, at the
       time such error is discovered, correct such error by making such
       adjustments in allocating contributions, forfeitures, and earning and
       valuation adjustments as they may deem fair and equitable, without the
       necessity of making retroactive adjustments in the accounts of
       Participants.  The Committee shall furnish each Participant a record of
       his account.

 4.06  DETERMINATION OF COMPENSATION.  The Companies shall furnish to the
       Committee information as to the Compensation and contributions of a
       Participant for each Plan Year, and, for the purposes of this Agreement,
       the Committee shall accept such information furnished by the Companies as
       correct, and the amount of the Compensation and contributions as so
       certified to the Committee by the Companies shall be binding and
       conclusive on all persons whomsoever, unless a Participant files a
       written objection with the Committee as to the Compensation or
       contributions so certified within thirty (30) days from the date he has
       been notified thereof.

 4.07  DESIGNATION OF BENEFICIARY.

       (a) Each Participant shall have the right to designate the Beneficiary or
           Beneficiaries who are entitled to receive any amount or benefit in
           case of the Participant's death and shall have the right at any time
           prior to final distribution of his accounts to change the Beneficiary
           or Beneficiaries theretofore designated by him by filing a new
           designation; provided, that such Beneficiary shall be deemed to be
           the surviving spouse of such Participant unless a spousal consent
           under Subsection (b) has been signed by the surviving spouse. Each
           such new designation shall completely revoke all designations
           previously filed by the same Participant. All designations shall be
           in writing and filed with the Committee and may be included in the
           Agreement of Participation and Designation of Beneficiary, or in such
           other form or forms as the Committee shall require. The Trustee, at
           the direction of the Committee, shall make settlement hereunder at
           the time of the Participant's death with such Beneficiary or
           Beneficiaries as shall be designated by said Participant during his
           lifetime.

       (b) Any designation of a Beneficiary other than his spouse by the
           Participant shall not take effect unless the spouse consents to such
           designation. Such consent must acknowledge the effect of the
           designation, shall be a consent to a specific Beneficiary and to a
           specific form of benefit, and be witnessed by a Plan representative
           or a notary public. Any consent shall be effective only as to such
           spouse. Such designation of a Beneficiary shall take effect without
           the spousal consent only if it is established to the satisfaction of
           a Plan representative that the consent may not be obtained because
           there is no spouse, because the spouse cannot be located, or because
           of such other circumstances as the Secretary of the Treasury may by
           regulations prescribe.

        to the plans set forth below.

       (a) Effective July 1, 1984, assets and liabilities for staff employees
           under the Combined Profit Sharing Plan were transferred to the
           Combined International Corporation Staff Employees' Profit Sharing
           Plan ("Combined Staff PST"), and to this Plan. Assets and liabilities
           from the mandatory and voluntary contribution accounts of staff
           employees therein were transferred to their respective participant's

           and health insurance agents and of life insurance agents in the
           Combined Profit Sharing Plan remained in such plan, which was renamed
           the Combined International Corporation Field Sales Agents' Profit
           Sharing Plan.

       (b) Effective July 1, 1984, the Ryan Insurance  Group, Inc.  Profit
           Sharing Plan was similarly merged into the Combined Staff PST, and
           into this Plan, with assets and liabilities from the participants,
           voluntary contribution accounts therein being transferred to their
           respective participant's voluntary contribution accounts in this plan
           and the company contribution accounts therein being transferred to
           their respective company contribution accounts in the Combined Staff
           PST.

       (d) Effective July 1, 1984, Participants under the above plans became
           Participants in the Combined Staff PST and were given up to five
           years of benefit credit under the Combined International Corporation
           Pension Plan, but were not allowed to elect Basic Pay Deferral
           Amounts until they satisfied the eligibility requirements of section
           2.01.

       (e) Effective January 1, 1989, assets and liabilities for employees under
           the Miller, Mason & Dickenson, Inc. Employee Stock Ownership Plan
           were transferred to this Plan. Assets and liabilities from the
           voluntary contribution accounts of employees therein were transferred
           to their respective Participant's Voluntary Contribution Accounts in
           this Plan, and assets and liabilities from their employer
           contribution accounts therein were transferred to their respective
           Company Contribution Accounts in this Plan.

                                                                   Page 33 of 92
 
       (f) Effective January 1, 1989, assets and liabilities for staff employees
           under the Aon Profit Sharing Plan (formerly the Combined Staff PST)
           were transferred to this Plan. Such assets and liabilities from their
           company contribution accounts therein were transferred to their
           respective Company Contribution Accounts in this Plan.

       (g) Effective January 1, 1989, Combined Insurance Field Sales Agents'
           Profit Sharing Plan (formerly the Combined Profit Sharing Plan) was

       (h) Participants under the above plans immediately became Participants in
           this Plan and were allowed to elect Basic Pay Deferral Amounts
           whether or not they satisfied the eligibility requirements of Section
           2.01.

                 following compliance with the requirements of Section 2.01(c)
                 of this Plan. A Former Hall Employee who was not a Participant
                 in the Hall Plan on December 31, 1992, shall become a
                 Participant in this Plan in accordance with Section 2.01 of
                 this Plan on the earlier of:

                                                                   Page 34 of 92
 
                (A) shall be credited with the number of full years of Service
                    computed under the elapsed-time provisions of the Hall Plan
                    as of December 31, 1992; and

                    on the Employee's date of hire.

          (iii) Vesting.  For purposes of satisfying Section 9.01 of this Plan
                (relating to vesting), service for Hall shall be considered

          (iv)  Account Balance.  The value of the account of each Participant
                who was a participant in the Hall Plan on December 31, 1992,
                shall be determined as of December 31, 1992, and that balance
                shall be transferred to the trust of this Plan on January 1,
                1993, and shall constitute (in addition to any existing Account
                balance in the Plan), the balance in the Account of such
                Participant as of January 1, 1993.

          (v)   Other Provisions.  The provisions of this Plan which shall be
                applicable to the Hall Plan prior to January 1, 1993, and their
                retroactive effective dates, are as specified on Schedule B,
                which is attached and made a part of this Plan.

          (vi)  Benefit Options.  Benefit options under the Hall Plan which
                shall continue to apply to accrued benefits are set forth in
                Schedule B.  To the extent such accrued benefits are accounted
                for separately, any amount withdrawn under the terms of the Plan
                shall be charged first to the account maintained for such
                accrued benefits.

                Employee who was a participant in the K&K Plan on July 31, 1993,
                became a Participant in this Plan on August 1, 1993, following

                Plan upon satisfaction of the requirements of Section 2.01 of
                this Plan.

          (ii)  Service.  For purposes of satisfying Section 2.01, a Former K&K
                Employee who was not a participant in the K&K Plan on July 31,
                1993, shall receive credit for Hours of Service performed for
                K&K as if they were hours of service performed for the Company.

          (iii) Vesting at Age 62.  Any Employee who was a participant in the
                K&K Plan with three years of service under the K&K Plan as of
                July 31, 1993, shall be fully vested in his account balance upon
                attainment of age 62.

          (iv)  Vesting.  For purposes of satisfying Section 9.01 of this Plan
                (relating to vesting), service for K&K shall be considered
                Service for the Company.  In the case of a Participant who has
                five consecutive One-Year Breaks-in-Service, Service, after such
                Break-in-Service, shall not be taken into account for the
                purpose of determining his nonforfeitable interest in his
                Accounts before such Break-in-Service.  In addition, with
                respect to a Participant who was a participant in the K&K Plan
                on July 31, 1993, the following shall apply:  notwithstanding
                the provisions of Section 9.01 of this Plan, a Participant who

       (b) Contributions made by or on behalf of a Participant shall continue to

           the Trustees pursuant to this Section 5.02 (except as otherwise
           provided under Department of Labor Regulations (S) 2550.404(c)-
           1(b)(2)(ii)(B) and (d)(2)(ii)).

           Trustee as to the manner in which Fund shares allocated to his
           accounts are to be voted on each matter requiring a shareholder vote.
           Shares shall be voted on a portfolio or aggregate basis, as
           determined by the Fund.

       (b) Before each vote, the Trustees shall cause to be furnished to each
           Participant (or Beneficiary) a copy of the proxy solicitation
           material, together with a form

                                      70

                                                                   Exhibit 10(f)
                                                                   Page 40 of 92
 
           requesting confidential direction as to how the shares allocated to
           his accounts are to be voted by the Trustees.

       (c) Upon timely receipt of directions, the Trustees shall vote the shares
           (including fractional shares) of stock allocated to such
           Participant's (or Beneficiary's) accounts as directed by the
           Participant (or Beneficiary). Each Participant (or Beneficiary) who
           timely directs voting of Fund stock on an aggregate (or portfolio)
           basis shall also direct the vote of a portion of the shares of Fund
           (or shares of the portfolio, if applicable) for which signed voting
           directions are not timely received. Each such Participant (or
           Beneficiary) shall be entitled to direct the voting of that number of
           the undirected shares resulting from multiplying the total number of
           undirected shares (on an aggregate or portfolio basis, as shall be
           determined by the Fund) by a fraction, the numerator of which is the
           total number of shares allocated to that Participant's accounts and
           the denominator of which is the total number of shares of all
           participants who timely direct the voting of Fund shares.

       (d) Each Participant (or Beneficiary) may direct the Trustees as to how
           to respond to an exchange offer with respect to Fund shares allocated
           to his accounts. The Trustees shall use their best efforts to timely
           distribute or cause to be distributed to each Participant (or
           Beneficiary) such information as will be distributed to stockholders
           of the Fund in connection with any exchange offer. Upon timely
           receipt of written instructions as to the tendering or exchanging of
           Fund stock, the Trustees shall act as instructed with respect to
           shares of Fund stock allocated to such Participant's (or
           Beneficiary's) accounts. If the Trustees do not receive timely
           written instructions from a Participant (or Beneficiary) as to the
           manner in which to respond to such exchange offer, the Trustees shall
           not exchange any Fund shares with respect to which such Participant
           (or Beneficiary) has the right of direction.

       (e) The Participants' individual instructions are to be given to the
           Trustees or the Trustees' designee, and such person shall not divulge
           the Participant's directions to any person.  Instructions so received
           shall be held in strict confidence and shall not be divulged or
           released to any person except as may be required to vote at the
           shareholders' meeting, or as required by federal or state laws not
           preempted by ERISA.  The Trustees shall be responsible for monitoring
           compliance with confidentiality procedures.

       (f) Each Participant (or Beneficiary) shall be considered a "named
           fiduciary" under section 402(a)(2) of ERISA with respect to all
           voting directions.

 5.04  LACK OF VALID ELECTION.  If a valid election under Section 5.02 is not
       made but the Participant or Beneficiary of a deceased Participant has
       made a valid prior election, then all amounts shall remain in their
       present fund.  If a Participant, or

                                                                   Page 41 of 92
 
       Beneficiary of a deceased Participant, has not made a valid election and
       no prior valid election is in effect, then all amounts in respect to
       which a valid election has never been made shall be invested in a money
       market fund, or as otherwise directed by the Trustees.

 5.05  FUNDS FOR INVESTMENT.  The Trustees shall determine, from time to time,
       the Investment Funds available to Participants, except that there shall
       be established under this Plan an Investment Fund holding exclusively
       shares of the common stock of Aon Corporation, except as provided under
       subsection (a) of this Section 5.05, to be called the Aon Stock Fund.
       The trustee of the Aon Stock Fund shall be the Institutional Trustee.

       (a) A portion of the Aon Stock Fund may also be invested in short-term
           United States Government obligations, other short-term obligations
           guaranteed by the United States Government, commercial paper, or
           money market funds for qualified employee benefit trusts while
           awaiting investment in Employer stock, or to provide sufficient
           liquidity to satisfy Participants' request for withdrawals and
           distributions.

       (b) The following provisions shall apply with respect to voting shares of
           Aon common stock:

          (i)   Each Participant (or Beneficiary) shall have the right to direct
                the Institutional Trustee as to the manner in which shares of
                Aon common stock allocated to his accounts are to be voted on
                each matter brought before an annual or special stockholders'
                meeting of Aon.

          (ii)  Before each such meeting of stockholders, the Institutional
                Trustee, or Aon, upon written notice to the Institutional
                Trustee, shall cause to be furnished to each Participant (or
                Beneficiary) a copy of the proxy solicitation material, together
                with a form requesting confidential direction as to how the
                shares of Aon common stock allocated to such Participant's
                accounts are to be voted by the Institutional Trustee.

          (iii) Upon timely receipt of such directions, the Institutional
                Trustee shall vote the shares (including fractional shares) of
                Aon common stock allocated to such Participant's accounts on
                each matter as directed by the Participant.  Each Participant
                (or Beneficiary) who timely directs voting of Aon common stock
                shall also direct the vote of a portion of the shares of Aon
                common stock for which signed voting directions are not timely
                received.  Each such Participant (or Beneficiary) shall be
                entitled to direct the voting of that number of the undirected
                shares resulting from multiplying the total number of 
                undirected shares by a fraction, the numerator of which is the
                total number of

                shares allocated to that Participant's accounts and the
                denominator of which is the total number of shares of all
                Participants who timely direct the voting of Aon common stock.

          (iv)  The Participants' individual instructions are to be given to the
                Institutional Trustee, or to any other person who is not the
                Company, a subsidiary, or an employee, officer, or director
                thereof and such person shall not divulge the Participant's
                directions to any person.  Instructions so received shall be
                held in strict confidence and shall not be divulged or released

                Trustee as to how to respond to a tender or exchange offer with
                respect to shares of Aon common stock allocated to his accounts.
                The Institutional Trustee or Aon, upon written notice to the
                Institutional Trustee, shall use its best efforts to timely
                distribute or cause to be distributed to each Participant (or
                Beneficiary) such information as will be distributed to
                stockholders of the Company in connection with any such tender
                or exchange offer.  Upon timely receipt of written instructions
                as to the tendering or exchanging of Aon common stock, the
                Institutional Trustee shall act as instructed with respect to
                shares of Aon common stock allocated to such Participant's (or
                Beneficiary's) accounts.  If the Institutional Trustee does not
                receive timely written instructions from a Participant (or
                Beneficiary) as to the manner in which to respond to such a
                tender or exchange offer, the Institutional Trustee shall not
                tender or exchange any shares of Aon common stock with respect
                to which such Participant )or Beneficiary) has the right of
                direction.  The participants' individual instructions shall be
                given to the Institutional Trustee  or to any other person who
                is not the Company, a subsidiary, or an employee, officer or
                director thereof and such person shall not divulge any
                Participant's directions to any person, except as required by
                federal or state law not preempted by ERISA.

          (vi)  Each Participant (or Beneficiary) shall be considered a "named
                fiduciary" under section 402(a)(2) of ERISA with respect to all
                voting directions.

       (c) The Institutional Trustee shall be responsible for monitoring and
           safeguarding the confidentiality of information relating to the
           purchase, sale, and holding and exercise of voting and similar rights
           of Participants.

 5.06  INVESTMENT OF THE SEPARATE FUNDS.  Except with respect to the Aon Stock
       Fund, the Trustees shall have full power and authority to receive,
       collect, receipt for,

                                                                   Page 43 of 92
 
       hold, manage, and care for all amounts held, paid and contributed to each
       of the separate funds described in Section 5.02, and the proceeds thereof
       and the income and profits therefrom, as a single fund, and to invest and
       reinvest the same as provided in Section 5.02, provided that all
       investments shall comply with the requirements of Section 404 of ERISA.
       Also except with respect to the Aon Stock Fund the Trustees are further
       authorized and empowered to sell, exchange, convert, or transfer any
       property of the Trust; to sell covered stock options; to retain
       uninvested for such time as the Trustee deems for the best interest of
       the Trust any cash held in any separate fund; to exercise or dispose of
       all rights accruing to the holders of any securities; to join in, by
       deposit, pledge, or otherwise, any plan of reorganization or other means
       of protecting and dealing with securities; and to compromise, adjust, and
       settle, all claims of or against said Trust at such amounts and upon such
       terms as the Trustee deems advisable.

       Powers of the Institutional Trustee are as set forth in the agreement
       between the Company and the Institutional Trustee.

 5.07  INVESTMENTS NOT ALLOCATED TO SEPARATE ACCOUNTS.  All right, title, and
       interest in and to the assets and investments held in each separate fund
       shall be vested in, and reside exclusively in, the Trustee or the
       Institutional Trustee, as applicable, and no Participant shall have any
       right, title, or interest in or to the assets or investments of any fund
       except to have the same held, invested, and applied in accordance with
       the provisions of this agreement.  The maintenance of separate accounts
       for each Participant, as heretofore provided, shall not require the
       allocation of or segregation of assets to each such account, but the
       creation of such accounts is primarily for accounting purposes and
       designed to reflect the dollar interest of each such account in the
       separate funds.

                                                                   Page 44 of 92
 
                   SECTION 6 - PROVISIONS RELATING TO TRUSTEE


 6.01  APPOINTMENT OF TRUSTEES AND INSTITUTIONAL TRUSTEE.  There shall at all
       times be one or more individual Trustees and an Institutional Trustee
       acting hereunder.  Such individual Trustees and the Institutional Trustee
       shall be appointed by the Board.  The Board shall have the right at any
       time, and from time to time, to remove any individual Trustee or the
       Institutional Trustee.  Each individual Trustee and the Institutional
       Trustee shall serve until 60 days after the earlier of (a) the day notice
       of resignation is given to the Board (or its representative); or (b) the
       day notice of removal by the Board (or its representative) is given to
       the Trustee or Institutional Trustee.  By mutual agreement, the 60-day
       notice may be waived.  In the event of the death, resignation, or removal
       of an individual Trustee or the Institutional Trustee acting hereunder,
       the Board shall appoint a successor to fill the vacancy, and such
       successor, upon accepting appointment by an instrument in writing
       delivered to the Board (or its representative) shall, without further
       action, become vested with all the estate, rights, powers, discretions
       and duties of the predecessor.

 6.02  FEES AND EXPENSES OF TRUSTEE.  The Trustee shall be paid such reasonable
       compensation as shall from time to time be agreed upon by Aon and the
       Trustee except that no person so serving shall be entitled to receive
       compensation where he receives fulltime pay from the Companies.  The
       Trustee, in addition, shall be reimbursed for any reasonable expenses,
       including reasonable counsel fees and investment manager fees, incurred
       by it in the administration of the Trust.

 6.03  PAYMENT OF COSTS, FEES AND EXPENSES.  Expenses arising from the
       administration, management and operation of the Plan and the funds
       described in Section 5.02, including compensation payable to the Trustee
       or Institutional Trustee, shall be payable from the fund to which such
       expenses relate or to which such expenses or a portion thereof are fairly
       allocable.  In construing the foregoing, the following shall be
       understood: (1) expenses incurred in connection with transactions
       involving the purchase or sale of investments shall be added to the cost
       of such investment or deducted from the sale price thereof as the case
       may be; and (2) nothing contained herein shall preclude the Companies, by
       agreement or otherwise, from paying expenses not attributable to them
       hereunder.

 6.04  UNCERTAIN DISTRIBUTION.  In the event any question or dispute shall arise
       as to the proper person or persons to whom any payment shall be made, the
       Trustee may withhold such payment until a determination of such question
       or dispute shall have been made, or the Trustee shall have been
       adequately indemnified against loss to its satisfaction.

 6.05  LIABILITY. No Trustee shall ever be liable for any act or default by any
       predecessor Trustee, nor shall any successor Trustee or Trustees acting
       hereunder be under any duty to examine into or take any action with
       reference to the accounts of any

                                      75

                                                                   Exhibit 10(f)
                                                                   Page 45 of 92
 
       prior Trustee heretofore acting hereunder.  All contributions and other
       monies received by the Trustee shall be held for the exclusive benefit of
       the Participants and their Beneficiaries and for the payment of such
       administrative expenses as may be provided for hereunder.  The Trustee
       shall be accountable for all such contributions and other monies, but
       shall have no duty to determine that the amounts of the contributions
       comply with the provisions of the Plan.

 6.06  LEGAL ACTION.  The Trustee shall at no time be obliged to institute any
       legal action or to become a party to any legal action unless it shall
       have been indemnified to its satisfaction for any fees, costs, and
       expenses to be incurred in connection therewith.

 6.07  MANNER OF ACTING.  The duties of the Institutional Trustee shall be as
       set forth in Section 6.08.  In all other matters, all decisions by the
       Trustees pertaining to the management of the Trust and their duties and
       powers, shall be made by the decision of the majority of the Trustees,
       and the action of the majority of the Trustees shall be binding upon all
       of the Trustees and have the same effect as an action, or decision, of
       all the Trustees.

 6.08  DUTIES OF INSTITUTIONAL TRUSTEE.  The Institutional Trustee of the Aon
       Stock Fund shall be responsible for performing one or more of the duties
       and powers prescribed to the Institutional Trustee under this agreement
       solely with respect to the Aon Stock Fund, and under any other agreement
       between the Company and the Institutional Trustee.  Such other agreement
       shall be in writing and shall be signed by and on behalf of the Company
       and the Institutional Trustee.  In the event of a conflict between this
       agreement and such other agreement, the term of such other agreement
       shall control.

       The Trustees shall be responsible for performing the duties and powers
       prescribed to the Trustees under this Section 6, with respect to all
       other assets of the Trust.

 6.09  LIMITATION ON LIABILITY.  To the extent permitted by law, each person
       serving as a Trustee without compensation shall be relieved and released
       from all personal liability by reason of any act or failure to act on his
       part, except to the extent such act or failure to act was a result of
       fraud or gross negligence.

 6.10  INDEMNITY.  Each person serving as a Trustee without compensation (and
       their respective assigns, heirs, executors and administrators) shall be
       entitled to be indemnified by Aon against all costs and expenses
       reasonably incurred by or imposed upon him in connection with or
       resulting from any action, suit or proceeding or threat thereof, to which
       he may be made a party by reason of his serving as a Trustee, except in
       relation to matters as to which a recovery shall be had against him by
       reason of his having been finally adjudged in such action, suit or
       proceeding to have committed a fraudulent act or omission.  The foregoing
       right to indemnity shall include reimbursement of the costs and expenses
       paid in

                                      76

                                                                   Exhibit 10(f)
                                                                   Page 46 of 92
 
       settling any such action, suit or proceeding or threat thereof when it
       appears to Aon that the Trustee did not commit a fraudulent act or
       omission.

 6.11  DISBURSEMENTS. The Trustee shall make such disbursements or payments from
       the Investment Funds as described in Section 5.02 as may be directed by
       the Committee.  Any such directions shall be in writing and signed by a
       member of the Committee or the Secretary of the Committee.  The Trustee
       shall have no duty or obligation to inquire into the propriety of any
       payment directed by the Committee but may conclusively presume that the
       payment is authorized by the terms of the Plan; however, this Section
       shall in no event be construed as granting the Committee any authority to
       manage, control, or invest the assets of the Trust but is intended solely
       to facilitate the administration of the Plan by the Committee.

 6.12  REPORTS.  The Trustee shall maintain accurate and detailed records and
       accounts of all investments, receipts, disbursements and other
       transactions hereunder, and all accounts, books and records relating
       thereto shall be open at all reasonable times to inspection and audit by
       any person or persons designated by Aon or the Committee.  Within sixty
       (60) days following the close of each Plan Year (or following the close
       of such other periods as may be agreed upon by the Trustee and Aon) the
       Trustee shall file with Aon a written account setting forth a description
       of all securities and other property purchased and sold, all receipts,
       disbursements and other transactions affected by it during such period,
       and listing the securities and other property held by it at the end of
       such period, at their cost and fair market values.  Aon may approve such
       accounting by written notice of approval delivered to the Trustee or by
       failure to express objection to such accounting in writing delivered to
       the Trustees within eight (8) months from the date upon which the
       accounting was delivered to Aon.  Upon receipt of a written approval of
       the accounting, or upon the passage of said period of time within which
       objections may be filed, without written objections having been delivered
       to the Trustee, such accounting shall be deemed to be approved, and the
       Trustee shall be released and discharged as to all items, matters and
       things set forth in such accounting as if such accounting had been
       settled and allowed by a decree of a court of competent jurisdiction in
       any action or proceeding in which the Trustee, Aon, and all persons
       having or claiming to have any interest in the Trust Fund or under the
       Plan, were parties.  The Trustee, nevertheless, shall have the right to
       have its accounts settled by judicial proceedings if it so elects, in
       which event only the Trustee and Aon shall be necessary parties.  Nothing
       contained in this paragraph shall relieve the Trustee from any
       responsibility or duty under ERISA and any subsequent amendment thereto.

 6.13  ADDITIONAL POWERS OF TRUSTEE.  The Trustee shall have exclusive authority
       and discretion to manage and control  all of the assets of the Plan
       except for the assets of the Aon Stock Fund. Pursuant thereto, and in
       addition to the other powers granted by this Agreement, the Trustee shall
       be authorized and empowered, except with respect to the Aon Stock Fund:

 (a) To sell, exchange, convey, transfer, or otherwise dispose of any property
 held by it, by private contract or at public auction, and no person dealing
 with the Trustee shall be bound to see to the application of the purchase money
 or to inquire into the validity, expediency, or propriety of any such sale or
 other disposition;

       (b) To make, execute, acknowledge, and deliver any and all documents of
           transfer and conveyance and any and all other instruments that may be
           necessary or appropriate to carry out the powers herein granted;

       (c) To register any investment held for an Investment Fund in its own
           name or in the name of a nominee and to hold any investment in bearer
           form, but the books and records of the Trustee shall at all times
           show that all such investments are part of the Trust Fund;

       (d) To manage, administer, operate, lease for any number of years,
           develop, improve, repair, alter, demolish, mortgage, pledge, grant
           options with respect to, or otherwise deal with any real property or
           interest therein at any time held by it;

       (e) To employ suitable agents and persons to render it services and
           advice in connection with its responsibilities and to pay their
           reasonable expenses and compensation;

       (f) To settle, compromise, or submit to arbitration, any claims, debts,
           or damages, due or owing to or from the Trust, to commence or defend
           suits or legal proceedings and to represent the Trust in all suits or
           legal proceedings;

       (g) To enter into any covenants or agreements binding the Trust with
           regard to any securities or other property held by it as Trustee; and

       (h) To borrow or raise monies for the purposes of the Trust and for any
           such so borrowed to issue its promissory note as Trustee and to
           secure the repayment thereof by pledging all or any part of the
           assets of the Trust, but nothing herein contained shall obligate the
           Trustee to render itself liable individually for the amount of any
           such borrowing; and no person loaning money to the Trustee shall be
           bound to see to the application of the money loaned or to inquire
           into the validity, expediency, or propriety of any such borrowing.

 
 6.14  INVESTMENT MANAGER.  The Trustees or the Company may delegate the
       investment powers granted to the Trustee by this Plan to an investment
       manager provided such investment manager meets all the requirements set
       forth in Section 3(38) of ERISA.  In the event of the delegation of their
       investment powers as above provided, the Trustees shall have no duty or
       obligation to supervise or control in any way the investments made and
       shall in no way be liable or responsible on account

       of any investments made or retained by the investment manager, whether or
       not such investments are authorized by this Plan, or for any acts or
       omissions of the investment manager.  Such delegation may apply to any
       part or all of the Investment Funds.

                    SECTION 7 - ADMINISTRATION OF THE PLAN


 7.01  COMMITTEE.  The Board shall appoint a Committee consisting of not less
       than three (3) nor more than seven (7) members.  Any person appointed a
       member of the Committee shall signify his acceptance by filing written
       acceptance with the Board.  The members of the Committee shall serve
       without compensation for their services.  The term of the members of the
       Committee shall commence with the date of their appointment and continue
       at the convenience of the Board.  Any member of the Committee may resign
       by delivering his written resignation to the Board, and such resignation
       shall become effective at delivery or at any later date specified
       therein.

 7.02  DUTIES OF COMMITTEE.  The Committee shall have those duties prescribed to
       it elsewhere in this Agreement, and shall be responsible for the general
       administration of the Plan except where duties in connection with such
       general administration have been prescribed to others under this
       Agreement.  The Committee shall not incur expenses on behalf of the Plan
       or Trust except with the consent of Aon.

 7.03  CHAIRMAN AND SECRETARY.  The members of the Committee shall elect a
       chairman from their number, and a secretary who may be but need not be
       one of the members of the Committee.

 7.04  MEETINGS AND QUORUM.  The Committee shall hold meetings upon such notice,
       at such place or places, and at such time or times as it may from time to
       time determine.  A majority of the members of the Committee at the time
       in office shall constitute a quorum for the transaction of business.  All
       resolutions or other actions taken by the Committee at any meeting shall
       be by the vote of a majority of the members of the Committee present at
       the meeting.  Actions may be taken by the Committee without a meeting
       where such actions are consented to in writing by the entire Committee.

 7.05  ALLOCATION OF DUTIES.  The Committee, by its action, may allocate its
       fiduciary responsibilities among its members, and may designate persons
       other than its members to carry out its fiduciary responsibilities.  The
       Committee, individual members of the Committee allocated specific
       fiduciary responsibilities, and persons other than members of the
       Committee designated to carry out specific fiduciary responsibilities,
       may employ one or more persons to render advice with respect to their
       responsibilities.  If the Committee has allocated a specific fiduciary
       responsibility among its members, or has designated persons other than
       its members to carry out a specific fiduciary responsibility, it shall do
       the following things: (1) it shall make as a condition of such allocation
       or designation the fact that the Committee may terminate the allocation
       or designation at will; and (2) it shall report such allocation or
       designation to the Executive Committee of Aon

                                                                  Page 50 of 92
 
       who by its action, or by action of the Board, may order that such
       allocation or designation be terminated in which case it shall be done as
       soon as practicable.

 7.06  Aon.  Aon shall have the responsibility for hiring personnel in
       connection with the administration of the Plan (who shall be employees of
       Aon), and persons to perform services in connection with the
       administration of the Plan on an ad hoc basis, as may be required to
       carry out the provisions of the Plan.  In accordance with the exercise of
       such responsibility, Aon may employ a manager for the Plan, clerical
       help, accountants, investment consultants, management consultants, public
       relations consultants, attorneys (who may be counsel for Aon) and other
       individuals as may be necessary.

 7.07  RULES AND INTERPRETATION.  The Committee may, from time to time,
       establish rules and procedures for administration of the Plan not
       inconsistent with the Plan's provisions, and administer the Plan in
       accordance with such provisions and such rules and procedures.  The
       Committee shall have the exclusive right and discretionary authority to
       construe the terms and provisions of the Plan, including without
       limitation, the power to construe or interpret disputed, ambiguous or
       uncertain terms, and  such other powers as may be necessary to carry out
       the provisions of the Plan.  The Committee shall also have the
       discretionary authority to determine all questions relating to the
       eligibility of Employees to participate in the benefits of the Plan and
       the amount of such benefits, and resolve all questions pertaining to the
       administration, interpretation and application of the Plan provisions.
       Actions taken in good faith by the Company, the Committee or an Employer
       shall be conclusive and binding on all interested parties as to all
       questions of interpretation and application under this Plan and as to all
       other matters arising out of the administration thereof, and shall be
       given the maximum possible deference allowed by the law.

 7.08  LIMITATIONS ON LIABILITY.  To the extent permitted by law, each member of
       the Committee, and each employee of the Company who is involved in the
       administration of the Plan, shall be relieved and released from all
       personal liability by reasons of any act or failure to act on his part
       with respect to the administration of the Plan, except to the extent such
       act or failure to act was a result of fraud or gross negligence.

 7.09  INDEMNITY. Each person named in Section 7.08 (and his respective assigns,
       heirs, executors and administrators) shall be entitled to be indemnified
       by Aon against all costs and expenses reasonably incurred by or imposed
       upon him in connection with or resulting from any action, suit or
       proceeding or threat thereof, to which he may be made a party by reason
       of his being involved in the administration of the Plan, except in
       relation to matters as to which a recovery shall be had against him by
       reason of his having been finally adjudged in such action, suit or
       proceeding to have committed a fraudulent act or omission.  The foregoing
       right to indemnity shall include reimbursement of the costs and expenses
       paid in

                                                                  Page 51 of 92
 
       settling any such action, suit or proceeding or threat thereof when it
       appears to Aon that the person did not commit a fraudulent act or
       omission.

 7.10  IDENTITY. The Committee shall have authority to determine the identity of
       the distributees, and in so doing, to act upon such information as, on
       reasonable inquiry, it may deem reliable with respect to heirship,
       relationship, survivorship, or any other fact relative to the
       distributees; the Committee may rely upon any affidavit, certificate,
       letter, or other paper or document reasonably believed by it to be
       genuine, and upon any evidence reasonably believed by it to be
       sufficient; and shall be protected and saved harmless in all payments
       required to be made hereunder, if made in good faith and without actual
       notice or knowledge of the changed condition or status of any person
       receiving payments upon a condition.

            SECTION 8 - DISPOSITION OF THE SEPARATE TRUST ACCOUNTS


 8.01  PARTICIPANT STILL EMPLOYED BY COMPANY AFTER RETIREMENT DATE.  A
       Participant shall have a 100% vested interest in his Company Contribution
       Account when he attains his Normal Retirement Date.  If he continues in
       active employment, no distribution shall be made to such Participant
       (except pursuant to Section 8.07) until he retires or is retired from
       active employment and the Committee is so advised, and he shall continue
       to participate in this Trust.

 8.02  DISPOSITION AT OR AFTER RETIREMENT DATE OR IN CASE OF PHYSICAL OR MENTAL
       DISABILITY.  In the event that at or after his Normal Retirement Date a
       Participant shall resign or be released from employment from the
       Companies, or in the event that the employment of any Participant shall,
       at any time, either before or after Normal Retirement Date, be terminated
       because of permanent physical or mental disability, then the Committee
       shall direct the Trustee to distribute the Participant's entire
       individual accounts to such Participant, without regard to the provisions
       for vesting as set forth in Section 9, in one or more of the ways
       described in Section 8.10. Permanent physical or mental disability means
       a physical or mental disability or illness which, in the opinion of a
       physician approved by the Committee, renders the Participant permanently
       incapable of performing the duties he was performing for the Companies
       when such disability began.

 8.03  DISPOSITION UPON THE DEATH OF A PARTICIPANT.  The Committee, upon the
       death of a Participant, whether before or after retirement, shall direct
       the Trustee to distribute the Participant's individual accounts, without
       regard to the provisions for vesting as set forth in Section 9, to such
       Participant's Beneficiary in one or more of the ways described in Section
       8.10. If the Participant has not named a Beneficiary, or if no
       Beneficiary is living at the death of the Participant, such accounts
       shall be paid over in one sum to the executor or administrator of the
       estate of such deceased Participant; provided, that if in such situations
       the Participant's spouse survives him then such surviving spouse shall be
       the Beneficiary.  In the event the Beneficiary dies subsequent to the
       death of the Participant but prior to the distribution of the entire
       accounts to the Beneficiary, the balance of the accounts shall forthwith
       be paid over and delivered to the executor or administrator of the estate
       of the deceased Beneficiary.

 8.04  DISPOSITION UPON TERMINATION OF EMPLOYMENT BEFORE REACHING RETIREMENT
       DATE.  If a Participant shall withdraw from the employ of the Companies
       prior to attaining his Normal Retirement Date, whether because of
       resignation or discharge, or any reason other than permanent disability,
       provision for which is made in Section 8.02, the Committee shall direct
       the Trustee to pay to such Participant his vested interest in his
       individual accounts, as provided in Section 9, in one or more of the ways
       described in Section 8.10. If prior to incurring a 1-Year Break in
       Service such terminated Participant shall file with the Committee

                                      83
<PAGE>
 
                                                                  Exhibit 10(f)
                                                                  Page 53 of 92
 
       an application for the payment of benefits which has been approved by the
       Committee and distributions pursuant thereto have commenced, and if prior
       to incurring such 1-Year Break in Service he shall be reemployed by one
       of the companies, he shall not share in the Companies' contribution or
       forfeitures for the Plan Year in which the withdrawal occurred (this
       assumes he reentered employment in the same year as the withdrawal
       occurred) and he shall not be entitled to make contributions, or to have
       contributions made on his behalf, under Section 3.03, 3.04 or 3.05 in
       respect to his Compensation for the 12 month period following the month
       in which his application is filed or following the month of termination
       of his employment, whichever shall occur later and, accordingly, shall
       not share in Companies' contributions and forfeitures on the basis of the
       contribution which would otherwise have been made on his behalf under
       Section 3.03 during this period.

 8.05  TERMINATION OF THE TRUST AND DISPOSITION UPON SUCH TERMINATION.  Unless
       otherwise terminated as hereinafter provided in Paragraphs (a), (b), (c),
       or (d), of this Section 8.05, this Trust and Plan shall continue in
       perpetuity or for such time as may be necessary to accomplish the purpose
       for which it is created.  This Trust and Plan shall terminate in respect
       to a Company upon the happening of any of the following events, but shall
       continue as a liquidation trust until final distribution of all assets.

       (a) Election by Aon. Aon, by appropriate resolutions by its Board, may
           elect to terminate this Trust and Plan as to any Company or all
           Companies.

       (b) Bankruptcy. In the event a Company at any time shall be adjudicated
           bankrupt or insolvent.

       (c) Dissolution. In the event a Company at any time shall be legally
           dissolved.

       (d) Merger or Consolidation. In the event of the merger or consolidation
           of a Company in and with another corporation or an association and
           such other corporation or association shall not agree to continue
           this Trust, with proper agreement with the Trustee and Committee;
           provided, however, in the event of dissolution, merger or
           consolidation of a Company, provision may be made by the successor or
           successors, whether it be an individual, firm, or corporation, for
           continuing this Trust and Plan, and such successor or successors
           shall be substituted for its predecessor hereunder, in which event
           the Trust and Plan shall continue in full force and effect in respect
           to such successor.

       If this Trust and Plan shall be terminated upon the happening of any of
       the events specified in Paragraphs (a), (b), (c), or (d) of this Section
       8.05, and in accordance with Section 401(k)(10(A)(i) of the IRC, the
       Committee shall direct the Trustee to distribute the value of the
       affected Participants' entire accounts to such Participants in the manner
       provided in Section 8.10. Upon the completion of all payments to everyone
       entitled thereto, this Trust and Plan shall finally cease

                                      84

                                                                  Exhibit 10(f)
                                                                  Page 54 of 92
 
       and terminate in respect to the Company and Participants affected
       thereby.  Upon the termination of the Trust and Plan in respect to any
       Company, any unallocated contributions, forfeitures, or earnings and
       valuation adjustments shall be allocated to the accounts of the affected
       Participants in a fair and equitable manner as determined by the
       Committee.  In the event of any action by or in respect to any Company
       resulting in the termination of the Trust and Plan pursuant to this
       Section 8.05, this Trust and Plan shall only terminate in respect to such
       Company but not in respect to any other Companies which have adopted the
       Plan, it being understood that the Trust and Plan shall continue in full
       force and effect as to any such other Companies.

 8.06  PAYMENT TO MINORS, ETC.  In case any payment hereunder becomes payable to
       a minor, person under legal disability, or person who by reason of
       physical or mental disability, although not adjudicated incompetent, is
       in the opinion of the Committee unable to administer properly such
       payment, then the same may be paid out by the Trustee for the benefit of
       such person in any of the following ways as the Committee, in its sole
       and uncontrolled discretion, shall determine:

       (a)  directly to such person; or

       (b) to the legally appointed guardian or conservator of such person; or

       (c) to some near relative of such person for the support, maintenance,
           and education of such person;

       (d) by the Trustee using such amounts directly for the benefit of such
           person.

       The payment and acceptance of any money or property in settlement of a
       participation under this Section 8.06 shall constitute a complete
       acquittance and discharge of all liability of the Trustee with respect to
       such participation.

 8.07  HARDSHIP WITHDRAWALS.  Hardship withdrawals may be made from the accounts
       of a Participant under the circumstances and subject to the limitations
       set forth in this Section.

       (a) A Condition of Hardship. For the purposes of this Section, a hardship
           shall mean financial needs of a Participant which are immediate and
           heavy and which cannot be satisfied by the Participant from other
           reasonably available resources. For example, an immediate and heavy
           financial need shall be deemed to exist if funds are needed for one
           of the following reasons: Expenses incurred or necessary for medical
           care (as defined in Section 213(d) of the IRC) of the participant,
           the participant's spouse, children, or dependents (as defined in
           Section 152 of the IRC); costs directly related to the purchase
           (excluding mortgage payments) of a principal residence for the
           participant; payment of tuition and related educational fees for the
           next 12 months of post-secondary eduction for the participant, the
           participant's

                                                                  Exhibit 10(f)
                                                                  Page 55 of 92
 
          spouse, children, or dependents; the need to prevent the eviction of
          the participant from or a foreclosure on the mortgage of, the
          participant's principal residence; or the need to meet funeral
          expenses of a family member.

       (b) Request for Payment.  In case of a condition of hardship, a
           Participant may request in writing to the Committee payment from his
           Participant's Pay Deferral Accounts (other than contributions to his
           Basic Pay Deferral Account for the current Plan Year) and Voluntary
           Contribution Account, plus an amount equal to 50% of the vested
           portion of the balance in his Company Contribution Account, of such
           amount as is necessary to meet the immediate and heavy financial need
           created by the hardship and not reasonably available from other
           resources. Such request shall be in writing and shall set forth all
           the applicable facts.

       (c) Objective Standards.  Subject to the approval of the Committee, there
           shall be paid to such Participant such portion, or all, of his
           request for payment hereunder as the Committee determines is
           necessary to alleviate such hardship. Consent to the withdrawal shall
           be given by the Committee if the Committee finds an immediate and
           heavy financial need and that the distribution is necessary in light
           of the standards set forth in the regulations and rulings of the
           Secretary of the Treasury or his delegate.

       (d) Order of Payment.   Payments to a Participant under this section
           shall be charged to his accounts in the following order:
           Participant's Voluntary Contribution Account (in the order described
           under Section 3.05), Participant's Supplemental Pay Deferral Account,
           Participant's Basic Pay Deferral Account (other than contributions to
           that account for the current Plan Year), Company Contribution
           Account.

       (e) Limitation on Withdrawals.

           (i)    In no event shall the total of the amounts paid to a
                  Participant under this Section exceed the balance in his
                  Participant's Accounts (less his contributions to his Basic
                  Pay Deferral Account during the current Plan Year) plus fifty
                  percent (50%) of the vested portion of his "Adjusted Company
                  Contribution Account" less the prior withdrawals referred to
                  in the following sentence. For the purpose of the preceding
                  sentence, a Participant's "Adjusted Company Contribution
                  Account" shall be deemed to be the balance in his Company
                  Contribution Account plus all prior withdrawals from such
                  account plus all prior withdrawals from such accounts under
                  the merged plans (as described in Section 4.08).

           (ii)   For Plan Years beginning on or after January 1, 1989, a
                  distribution for financial hardship shall not be made of
                  either earnings subsequent

                                                                  Page 56 of 92
 
                to December 31, 1988, on Pay Deferral Amounts or, to the extent
                required under regulations of the IRC, any matching or
                nonelective Company contributions treated as Pay Deferral
                Amounts under Section 3.09(e).

       (f) Withdrawals After Termination of Employment.  A withdrawal under this
           Section shall not be treated as a withdrawal under Section 8.04.

 8.08  NET EARNINGS AND VALUATION ADJUSTMENT.  Net earnings and valuation
       adjustments shall be made to the accounts of each Participant as set
       forth herein or under such separate agreement between the Company and the
       Institutional Trustee.  As of the last day of each calendar month, the
       Committee shall ascertain the net Gain or net Loss of each of the funds
       described in Section 5. Gain shall include profits actually realized and
       received and income earned plus any net increase in the fair market value
       of all of the assets of the fund since the date of their last valuation.
       Losses shall include expenses and losses actually incurred and paid plus
       any net decrease in the fair market value of all of the assets of the
       fund since the date of their last valuation.  The net Gain or net Loss of
       each Fund for the period shall then be allocated to or charged against
       the account or accounts of each Participant representing his interest in
       the fund in the proportion which the balance in his account or accounts
       (reduced by any amounts paid to him during the year) shall bear to the
       total of the balances in the accounts of all Participants representing an
       interest in the fund (reduced by any amounts paid to all of them during
       the year).  The allocation provided for in the preceding sentence shall
       be made before the allocation of the contributions of the Company, the
       Subsidiaries and the Participants for the period and before the
       allocations of any forfeitures for the period.

 8.09  METHOD OF VALUING ASSETS.  Valuation adjustments under Section 8.08 shall
       be based on the fair market value of the assets held by the Trustees and
       the Trustees shall adopt accepted valuation and accounting methods in
       determining fair market value.

 8.10  GENERAL PROVISIONS REGARDING PAYMENT OF BENEFITS.  If the person entitled
       to receive benefits pursuant to this Section 8 is a terminated or retired
       Participant or Beneficiary of a deceased Participant, the following shall
       apply:

       (a) He shall receive benefits in a lump sum or in equal periodic
           installments which at his discretion may be increased or accelerated
           or otherwise adjusted. Payment shall be made in a lump sum if the
           initial amount thereof is $5,000 or less; provided, that no
           distribution shall be made without the consent of the Participant if
           the amount thereof exceeds $3,500. If a distribution is one to which
           Sections 401(a)(11) and 417 of the IRC do not apply, such
           distribution may commence less than 30 days after the notice required
           under section 1.411(a)-11(c) of the Income Tax Regulations is given,
           provided that:

                                      87
<PAGE>
 
                                                                  Exhibit 10(f)
                                                                  Page 57 of 92
 
           (i)    the Committee clearly informs the Participant that the
                  Participant has a right to a period of at least 30 days after
                  receiving the notice to consider the decision of whether or
                  not to elect a distribution (and, if applicable, a particular
                  distribution option), and

           (ii)   the Participant, after receiving the notice, affirmatively
                  elects a distribution.

       (b) If he is a terminated or retired Participant, payment of benefits to
           him shall commence not later than the 60th day after the later of the
           close of the Plan Year in which his employment terminated or he
           attains his Normal Retirement Date; or if he is a Beneficiary of a
           deceased Participant, payment of benefits to him shall commence not
           later than the 60th day after the Plan Year in which the Participant
           of whom he is Beneficiary dies. Notwithstanding the preceding
           sentence, if he is a terminated or retired Participant, he shall have
           the right to have his benefits commence at a date later than
           described herein, but not beyond April 1st of the calendar year
           following the calendar year in which he attains age 70 1/2.

       (c) The Participant shall decide the method or methods to be used for
           paying him benefits, and, subject to what is stated in (b) above,
           when payment of benefits to him shall commence. He shall be given the
           opportunity to inform the Committee what his preferences are
           regarding the method or methods to be used for paying him benefits,
           and when payment of benefits to him shall commence.

       (d) If he is to receive payment of benefits in the form of periodic
           installments, such payments shall be made not less frequently than
           annually and shall be over a period of up to ten years but not to
           exceed the Participant's life expectancy or, if applicable, the
           combined life expectancy of the Participant and his Designated
           Beneficiary.

       (e) If he is a terminated Participant as described in Section 8.04,
           payment of benefits to him shall not commence until he has a 1-Year
           Break in Service except that the Committee shall commence payment to
           him sooner, as soon as administratively convenient, if he so
           requests.

       (f) Where distribution of the Participant's interest has begun under
           Section 8.10(b) and the Participant dies before his entire interest
           has been distributed to him, the remaining portion of such interest
           will be distributed at least as rapidly as under the method of
           distribution being used under Section 8.10(b) as of the date of his
           death.

       (g) If a Participant dies before the distribution of his interest has
           begun under Section 8.10(b) the entire interest of the Participant
           will be distributed within five years after his death except as
           described below:

                                                                  Exhibit 10(f)
                                                                  Page 58 of 92
 
           (i)   If any portion of the Participant's interest is payable to (or
                 for the benefit of) a Designated Beneficiary such portion will
                 be distributed over the life of such Designated Beneficiary (or
                 over a period not extending beyond the life expectancy of such
                 Beneficiary), and such distributions begin not later than one
                 year after the date of the Participant's death (or such later
                 date as the Secretary of the Treasury may prescribe), then for
                 purposes of this Subsection such portion shall be treated as
                 distributed on the date when such distributions began.

           (ii)  If such Designated Beneficiary is the surviving spouse of the
                 Participant, distributions need not begin until the date on
                 which the Participant would have attained age 70 1/2. If the
                 surviving spouse dies before distributions to her begin,
                 Section 8.10(g) shall be applied as if the surviving spouse
                 were the Participant. Any amount paid to a child shall be
                 treated as if it had been paid to the surviving spouse if such
                 amount will become payable to the surviving spouse upon such
                 child reaching majority (or other designated event permitted
                 under IRC regulations).

       (h) The term "Designated Beneficiary" means any individual designated as
           a Beneficiary by the Participant.

       (i) Notwithstanding the provisions of Subsection (b) hereof, distribution
           to a Participant who has terminated his service, or who is a 5% owner
           (as defined in Section 16.02(b)) at any time during the 5-Plan-Year
           period ending in the calendar year in which he attains age 70-1/2
           shall commence not later than the 1st day of April of the calendar
           year following the calendar year in which he attains age 70-1/2. If a
           Participant who has not terminated his service subsequently becomes a
           5% owner after the calendar year in which he attains age 70-1/2, then
           distribution shall commence by April 1st of the calendar year
           following the Plan Year during which he became a 5% owner. Effective
           January 1, 1989, distribution to a Participant shall commence by
           April 1st of the calendar year following the calendar year in which
           he attains age 70 1/2, without regard to whether he has terminated
           his service; provided, that this rule shall not apply to a
           Participant age 70-1/2 or over on January 1, 1988 unless he has been
           a 5% owner at any time during the Plan Year ending during the
           calendar year when he attained age 66-1/2 or any subsequent Plan
           Year, nor shall it apply to any benefits with respect to which a
           designation is in effect as described in Section 8.10(j).

       (j) The foregoing provisions of this Section 8.10, other than the right
           of a Participant to elect his own optional forms of benefit as may be
           applicable, shall not apply to distributions under a plan of
           distribution designated by a Participant in writing prior to January
           1, 1984, which was permissible under the provisions of this Plan as
           in effect prior to the 1984 Restatement of the Plan.

                                                                   Page 59 of 92

     (k) If the Beneficiary of the Participant is not his spouse the form of
         distribution must be one whereunder the present value of the retirement
         benefit payments projected to be made to the Participant, while living,
         is more than 50 percent of the present value of the total payments
         projected to be made to the Participant and the Participant's
         Beneficiary; provided, that this requirement shall be interpreted so as
         to comply with the incidental benefit rule of the IRC and the rules and
         regulations thereunder.

     (l) In lieu of making payments directly from a terminated, deceased, or
         retired Participant's separate accounts, the Committee may, in their
         sole discretion, invest all or a portion of such Participant's separate
         accounts in one or more annuity contracts and assign such contract or
         contracts to such Participant or his Beneficiary or cause payments to
         be made pursuant to the terms of such contract or contracts to such
         Participant or his Beneficiary in such manner as the Committee deem
         advisable. Before assigning any contract to a terminated or retired
         Participant or Beneficiary, the Committee shall cause such contract to
         be made non-assignable by the assignee. Any contract shall be issued on
         a unisex basis and all the terms and conditions under any such
         contract, including benefits, premiums, options, loan values and cash
         surrender values, shall be the same for both male and female.

     (m) Distribution to a Participant (or his Beneficiary) whose vested
         interest in his Accounts has a fair market value of $3,500 or less
         based on the Plan's last valuation shall be made as soon as
         administratively convenient.

     (n) Except as provided in regulations, the provisions of IRC Section
         401(a)(9) are hereby incorporated by reference to the extent not set
         forth in this Section.

8.11 ELIGIBLE ROLLOVER DISTRIBUTIONS. Effective with respect to distributions
     made on or after January 1, 1993, a distributee may elect, at the time and
     in the manner prescribed by the plan administrator, to have any portion of
     an Eligible Rollover Distribution paid directly to an Eligible Retirement
     Plan specified by the distributee in a Direct Rollover. For purposes of
     this Section 8.11:

     (a) An "Eligible Rollover Distribution" is any distribution of all or any
         portion of the balance to the credit of the distributee, except that an
         Eligible Rollover Distribution does not include: any distribution that
         is one of a series of substantially equal periodic payments (not less
         frequently than annually) made for the life (or life expectancy) of the
         distributee and the distributee's designated beneficiary, or for a
         specified period of ten years or more; any distribution to the extent
         such distribution is required under Section 401(a)(9) of the IRC; and
         the portion of any distribution that is not includable in gross income
         (determined without regard to the exclusion for net unrealized
         appreciation with respect to employer securities).

                                                                   Page 60 of 92
 
     (b) An "Eligible Retirement Plan" is an individual retirement account
         described in Section 408(a) of the IRC, an individual retirement
         annuity described in Section 408(b) of the IRC, an annuity plan
         described in Section 403(a) of the IRC, or a qualified trust described
         in Section 401(a) of the IRC, that accepts the distributee's Eligible
         Rollover Distribution. In the case of an Eligible Rollover Distribution
         to the surviving spouse, an Eligible Retirement Plan is an individual
         retirement account or individual retirement annuity.

     (c) A "Distributee" is an employee or former employee, the employee's or
         former employee's surviving spouse and the employee's or former
         employee's spouse or former spouse who is the alternate payee under a
         qualified domestic relations order, as defined in Section 414(p) of the
         IRC.

     (d) A "Direct Rollover" is a payment by the Plan to the Eligible Retirement
         Plan specified by the Distributee.

               SECTION 9--PARTICIPANT'S NONFORFEITABLE INTEREST


 9.01  GENERAL RULE.  A Participant's nonforfeitable (vested) interest prior to
       his Normal Retirement Date shall be an amount equal to the balance of his
       Participant's Voluntary Contribution Account, plus the balance of his
       Participant's Basic and Supplemental Pay Deferral Accounts, plus the
       percentage of the balance of his Company Contribution Account applicable
       to his number of Years of Participation as follows:

          Completed Years of Participation  Nonforfeitable Interest
          --------------------------------  -----------------------

                 Less than 1 year                       None
                 1 Year                                  20%
                 2 Years                                 40%
                 3 Years                                 60%
                 4 Years                                 80%
                 5 Years                                100%

       For the purpose of computing the balance of the Company Contribution
       Account of a Participant with less than a 100% vested interest, any
       amounts previously paid out pursuant to Section 8.07 shall be credited
       back to such Account and then charged against such Participant.  Upon the
       termination, or a partial termination, of this Plan, except as provided
       in Section 11, or upon complete discontinuance of contributions thereto
       by any Company, each affected Participant's interest in his separate
       accounts shall become one hundred percent (100%) nonforfeitable.

 9.02  SPECIAL RULES.  In applying the provisions of Section 9.01, Years of
       Participation shall refer to the total years of Service of an Employee
       with the following exceptions and modifications:

       (a) Subject to the provisions of (c) of this Section, an Employee's
           Service shall be deemed to commence on the January first following
           the date his actual employment commenced, except that if a prior
           Participant is reemployed and again becomes a Participant in the year
           of his reemployment pursuant to Section 2.02 his Service shall be
           deemed to have commenced on January first of the year of his
           reemployment.

       (b) If an Employee's employment is terminated during any calendar year,
           he shall receive no credit for any Service during such calendar year
           (unless the rule set forth in Section 1.23(c) applies).

       (c) In the case of an Employee who has five 1-Year Breaks in Service,
           Service, after such Break in Service, shall not be taken into account
           for the purpose of determining his nonforfeitable interest in his
           Company Contribution Account before such Break in Service.  As
           provided at Sections 2.02 and 4.01,

                                      92
<PAGE>

                                                                   Exhibit 10(F)
                                                                   page 62 of 92
 
           any nonforfeitable vested interest of a Participant in the balance of
           his Company Contribution Account at the time of such Breaks in
           Service shall be separately accounted for thereafter as one hundred
           percent (100%) nonforfeitable.

       (d) In the case of a Participant who becomes an independent field sales
           representative for the Companies (and thereby ceases to be an
           Employee) any period of time that he is acting in such capacity and
           during which his accounts are not distributed to him (except for
           hardship distribution under Section 8.07) shall be deemed to be
           Service.

       (e) Any period of time taken into account under the Combined Profit
           Sharing Plan, the Ryan Insurance Group, Inc.  Profit Sharing Plan, or
           the Union Fidelity Life Insurance Company Profit-Sharing Plan as of
           the date of merger of the first two of those plans into this Plan
           shall be taken into account under this Plan, and a similar rule shall
           apply as to the Aon Profit Sharing Plan, the Combined Insurance Field
           Sales Agents' Plan and the Miller, Mason & Dickenson, Inc.  Employee
           Stock Ownership Plan being merged into this Plan as of January 1,
           1989.

       (f) If the Plan becomes a Top-Heavy Plan and subsequently ceases to be
           such, the vesting schedule in Section 16.05 shall continue to apply
           in determining the vested interest of any Participant who had at
           least five years of Service as of December 31 in the last Plan Year
           of topheaviness.  For other Participants, said schedule shall apply
           only to their Top-Heavy Account as of such December 31.

       (g) A Participant's account shall be one hundred percent (100%) vested
           and nonforfeitable when he attains age 55 and completes five Years of
           Participation and such date shall be regarded as his early retirement
           date.

 9.03  RESTORATION OF FORFEITURES.  Forfeitures from a terminated Participant's
       Company Contribution Account shall be charged to his account upon
       termination of his employment; provided, that no forfeiture shall be
       incurred by a Participant reemployed before the next following
       Anniversary Date if he does not receive a distribution under Section 8.04
       by reason of such reemployment and if no administrative inconvenience as
       to such forfeitable amount would thereby be suffered by the Committee.
       If any terminated Participant who has suffered a forfeiture becomes
       reemployed before he has incurred five consecutive 1-Year Breaks in
       Service, upon his earning a year of Service after his rehire his Company
       Contribution Account shall be reconstituted by crediting thereto an
       amount equal to the amount forfeited, which amount shall be deducted from
       forfeitures during the Plan Year in which his Company Contribution
       Account is reconstituted.  To the extent forfeitures for such year are
       not adequate for such purpose, such amount as may be necessary to
       reconstitute his Company Contribution Account shall be deducted pro rata
       from the assets of those funds earning a net Gain

                                                                   Exhibit 10(F)
                                                                   page 63 of 92
 
       pursuant to the earnings and valuation adjustment under Section 8.08, and
       if there are no net Gains then such amount shall be deducted from Company
       contributions for the year.  As an alternative to either of the sources
       set forth in the preceding sentence, at the discretion of the Company
       such amount may be contributed by the Company as a special contribution
       and credited to such account.  In the event the employment of a rehired
       Participant whose account has been reconstituted is again terminated
       before he has acquired a one hundred percent (100%) vested interest, any
       prior distribution made to him on account of his prior termination of
       employment shall be taken into consideration in computing his vested
       interest at the time of his later termination of employment.

 9.04  APPLICATION OF OLD VESTING SCHEDULE.  Each Employee who has three or more
       years of Service on December 31, 1988, and who earns one Hour of Service
       after such date, shall have his vested interest determined under the
       provisions of this Plan as in effect on December 31, 1988, or under the
       terms of any merged plan under Section 4.08 of which he was a
       Participant, if such determination will result in increasing the
       percentage of his vested interest.

                                                                   Page 64 of 92
 
                        SECTION 10 - SPENDTHRIFT TRUST


10.01 GENERAL. No Participant or Beneficiary shall have any right or power to
      transfer, assign, anticipate, mortgage, pledge or otherwise encumber his
      interest in the Trust established by this Agreement, or his rights to
      receive payments or benefits from the Trust and neither such interest nor
      rights nor any assets of the Trust shall be subject to seizure or
      sequestration for the payment of any debts, judgments, alimony or separate
      maintenance owed by any Participant or Beneficiary nor to transferability
      by operation of law in the event of bankruptcy, insolvency or otherwise;
      provided, that this limitation shall not apply to a Qualified Domestic
      Relations Order ("QDRO") under IRC Section 401(a)(13) as amended from time
      to time.

10.02 QUALIFIED DOMESTIC RELATIONS ORDER. For purposes of this Section, a QDRO
      shall mean a domestic relations order which relates to alimony, child
      support or marital property rights and which has been determined by the
      Company to meet the requirements of IRC Section 414(p) as amended from
      time to time. The following rules shall apply to the rights and
      obligations of the spouse of a Participant (the "Non-Participant Spouse")
      under a QDRO and under a domestic relations order not yet determined to be
      a QDRO.

      (a) These rules shall apply prior to determination by the Company that
          the domestic relations order is a QDRO, and shall apply thereafter as
          applicable:

          (i)   As soon as administratively feasible after receipt of a domestic
                relations order, those funds which could go to the Non-
                Participant Spouse, if she (or he) is later determined by the
                Company to be entitled to these, will be put into a separate
                account.  These funds will be invested in the money market fund,
                except as otherwise may be directed by the Trustees, until the
                Non-Participant Spouse decides how to invest the funds and the
                Company is afforded reasonable time to honor the investment
                decision.  The Non-Participant Spouse may be allowed to begin
                making investment decisions even though the order is eventually
                determined not to be a QDRO.

          (ii)  The Non-Participant Spouse will share in any intervening gains
                (or losses) enjoyed (or suffered) by the Participant in his
                accounts between the time the Company is notified of the
                domestic relations order and the time a transfer of funds to the
                separate account of the Non-Participant Spouse can be
                accomplished.

          (iii) An account or account balances may be segregated for the Non-
                Participant Spouse even though the Participant is not yet
                eligible to have funds distributed to him.  The funds of the
                Non-Participant

                                                                   Page 65 of 92
 
                Spouse may be accounted for separately without the necessity for
                an escrow.

          (iv)  Once the Non-Participant Spouse does reach an investment
                decision, she (or he) will be entitled to invest her (or his)
                account balance among the same Investment Funds as are available
                to the Participant for investment.

          (v)   The Non-Participant Spouse may elect a Beneficiary for her (or
                his) account balances under the QDRO.  If a property settlement
                agreement is involved or some other court decree which is not a
                final divorce so that the individuals remain married, the
                Participant shall be treated as the death Beneficiary of the
                Non-Participant Spouse, just as the Non-Participant Spouse will
                be for the Participant, unless the QDRO provides otherwise.  If
                the QDRO provides that the Non-Participant Spouse is to be no
                longer regarded as the Participant's spouse, then the preceding
                sentence shall not apply.

          (vi)  Upon written notification from either the Participant or Non-
                Participant Spouse that a QDRO is forthcoming, no distribution
                of benefits or hardship withdrawals will be made to the
                Participant until a final determination has been made as to the
                qualified status of any domestic relations order received within
                the 90-day period following the date the Company sends the Aon
                QDRO Procedures to the parties.  If no domestic relations order
                is received by the Company within that 90 day period, a
                distribution or hardship withdrawal may be made to the
                Participant.

      (b) These rules shall apply once the domestic relations order has been
          determined to be a QDRO:

          (i)   The Non-Participant Spouse may withdraw all of her (or his)
                account balances at any time, without regard to whether the
                Participant has attained his (or her) earliest retirement age
                under the Plan.  Any benefits distributed under this rule may be
                taken out only in a single sum and may not be taken out
                periodically.

          (ii)  The Non-Participant Spouse may also be allowed to take a partial
                withdrawal of her (or his) account balances, but only in the
                event of a hardship in situations where the Participant could
                get a hardship distribution prior to separation from service.
                The test for a hardship will be whether the Non-Participant
                Spouse is suffering a hardship and not the Participant.  The
                same rules applicable for a partial withdrawal for hardship will
                be imposed on the Non-Participant Spouse as upon the
                Participant.  Any such partial distribution will be made pro
                rata from all of the accounts or sub-accounts of the Non-

                                      96

                                                                   Page 66 of 92
 
                Participant Spouse, including a pro rata portion of any
                nontaxable return of funds in the Participant's voluntary
                contribution account, if any.

          (iii) If the amount to be distributed to the Non-Participant Spouse
                is less than $3,500, such amount will be paid out only in a lump
                sum and may be distributed without the consent of the Non-
                Participant Spouse or of the Participant.

          (iv)  A distribution otherwise permissible may be made to the spouse
                without regard to whether the limitations on a distribution
                under IRC Section 401(a) or 401(k) are met.

      (c) It is the intent of Subsections (a) and (b) that the rules set forth
          therein shall be subject to, and shall be interpreted in light of, the
          requirements for a QDRO under the IRC and under regulations and
          rulings of the Secretary of the Treasury or his delegate.

      (d) Subsections (a) and (b) shall also apply to a child or other
          dependent of the Participant as appropriate.

      (e) This Section shall be incorporated into procedures in compliance with
          IRC Section 414(p) and adopted by the Committee by resolution.

               SECTION 11 - COMPANY TO HAVE NO INTEREST IN TRUST


         The Company shall in no event, either directly or indirectly, receive
any refund of contributions made to the Trust, nor directly or indirectly
participate in the distribution, or receive the benefits of the assets or funds
comprising the trust estate. Upon transfer to the Trustee, all responsibilities
of the Company for each contribution shall cease, and the Company shall have no
responsibilities for the acts of the Trustee or Committee. Notwithstanding the
first sentence of this Section, a refund may be made to a Company, subject to
the limitations imposed by Rev. Rul. 77-200, if a contribution is made by a
mistake of fact or a deduction for federal income taxes is disallowed for any
portion of a contribution and the mistaken contribution or the nondeductible
portion of the contribution is returned one year after payment of the mistaken
contribution or within one year after the disallowance of the deduction.

            SECTION 12 - AMENDMENT AND SUSPENSION OF CONTRIBUTIONS


12.01 AMENDMENT OF THE AGREEMENT. Aon reserves the right, by action of the
      Board, to amend this Agreement at any time, and from time to time,
      including the right to change the provisions for each Company's
      contributions. No amendment shall vest in the Companies any right, title
      or interest in and to the Trust Fund, or any part thereof, or cause them
      to be used or diverted to, purposes other than for the exclusive benefit
      of Participants and beneficiaries. The amendment of this Agreement shall
      not require the approval or ratification of the stockholders of Aon, or
      any Subsidiary, nor of the Trustee, Committee, Participants or
      Beneficiaries, or any of them; however, no amendment shall change the
      rights, duties, or responsibilities of the Trustee without its written
      consent. Except as may be necessary to qualify this Trust, or to continue
      the qualification of the Trust under Section 401 of the IRC, or any
      successor to such section, no amendment shall adversely affect vested
      rights of any Participant hereunder.

12.02 SUSPENSION. Aon reserves the right, by action of the Board, to suspend
      Aon's or any Subsidiary's contributions under Section 3.01(a)(iii) for any
      Plan Year, but not exceeding two successive Plan Years, without
      terminating the Plan and Trust or discontinuing contributions permanently,
      by providing written notice of such action of the Board to the Committee
      and Trustee not later than sixty (60) days prior to the end of such Plan
      Year, in which event the Company or Companies affected shall not be
      obliged to make any contribution to the Company Fund for the period of
      such suspension. The Committee upon receiving notice of such suspension
      shall immediately notify the affected Participants.

                                                                   Page 69 of 92
 
                  SECTION 13 - ADOPTION OF PLAN BY AFFILIATE


13.01 ADOPTION OF PLAN. Any Affiliate, by proper resolutions adopted by its
      Board, or by an adoption agreement executed by a principal executive
      officer, may become a party to this Agreement by adopting this Trust as a
      profit sharing plan for its Employees. A certified copy of such
      resolutions shall be delivered to the Committee and Trustee.

13.02 INTENTION OF PARTIES. Except as provided herein, it is the intention of
      the parties hereto that the Employees of Aon and the Employees of any
      Subsidiary that adopts this Trust shall receive the same benefits as they
      would receive if Aon and such Subsidiaries were one corporate entity and
      this Plan were the plan of such entity, and the provisions of this
      Agreement shall be interpreted in accordance with this intent.

13.03 TERMINATION OF STATUS OF SUBSIDIARY. In the event any Subsidiary adopting
      this Plan at any time does not meet the requirements herein set forth for
      a Subsidiary, such company shall nevertheless be considered as continuing
      its status as a Subsidiary unless Aon files with the Trustee and Committee
      a resolution adopted by its Board electing to discontinue such Company's
      participation hereunder. Such resolution shall be considered as an
      election to terminate such Company's participation in this Trust under the
      provisions of Section 8.05(a).

                         SECTION 14 - ERISA PROVISIONS


 14.01 SERVICE FOR PREDECESSOR.  To the extent required by regulations that may
       be prescribed by the Secretary of the Treasury or his delegate, service
       for a predecessor shall be treated as Service for the Companies.

 14.02 CONTROLLED GROUP.  To the extent required by IRC Section 414(b), (c),
       (m), (n) and (o) all employees of the entities described therein shall be
       treated as employed by a single employer.

 14.03 MERGER.  This Plan shall not be merged or consolidated with any other
       plan (or the assets held under this Plan shall not be transferred to any
       other plan), unless each Participant under the plan, if the plan then
       terminated, would receive a benefit equal to or greater than the benefit
       he would have been entitled to receive before the merger, consolidation,
       or transfer (if the plan had then terminated).

 14.04 CLAIMS PROCEDURE.  Pursuant to Section 503 of ERISA the following claims
       procedure is established.

       (a) A timely written application for benefits shall be filed with the
           Committee on a form prescribed by it.

       (b) If a claim is denied, in whole or in part, written notice of such
           denial shall be furnished to the applicant setting forth, in a manner
           calculated to be understood by him, the following:

           (i)   The specific reason or reasons for the denial;

           (ii)  A specific reference to pertinent Plan provisions on which the
                 denial is based;

           (iii) A description of any additional material or information
                 necessary for the claimant to perfect the claim and an
                 explanation of why such material or information is necessary;

           (iv)  An explanation of the Plan's claim review procedure.

       (c) An applicant whose claim has been denied in whole or in part (or his
           duly authorized representative) may appeal such denial to the
           Committee by making a written request for a review and may review
           pertinent documents and submit issues and comments in writing. A
           written request for review must be filed within sixty (60) days of
           the date an applicant has been notified of the denial or partial
           denial of his claim.

       (d)  The decision on review shall be made promptly, shall be in writing,
            and shall include specific reasons for the decision, written in a
            manner calculated to be understood by the applicant, and specific
            references to the pertinent Plan provisions on which the decision is
            based.


14.05  INVESTMENT IN DEPOSITS WITH CORPORATE FIDUCIARY.  In the event a
       corporate fiduciary is appointed, such fiduciary may invest all or a part
       of the Plan's assets in deposits, which bear a reasonable rate of
       interest, in an account maintained in its own banking department, to the
       extent such investment is permitted by Section 408(b) ERISA, and to the
       extent otherwise permitted under Section 5.05.


14.06  MAXIMUM ANNUAL ADDITION.

       (a)  In no event shall the annual addition (as hereinafter defined) to a
            Participant's separate accounts with respect to any Plan Year exceed
            the lesser of

            (i)    $30,000 (or, if greater, one-fourth of the defined benefit
                   plan dollar limitation under Section 415(b) of the IRC), or

            (ii)   Twenty-five percent (25%) of the Participant's total
                   compensation.

       (b)  The term "annual addition" means the sum  for  any Plan Year of

            (i)    his share of Company contributions, plus

            (ii)   the amount of his contributions under Section 3.05 made on or
                   after January 1, 1987, plus

            (iii)  his share of forfeitures, plus

            (iv)   for purposes of Section 14.06(a)(i) only, amounts allocated
                   to a separate account for the Participant to provide medical
                   benefits after retirement, whether under a pension or annuity
                   plan or a welfare benefit fund, pursuant to Sections 401(h),
                   415(c)(2), 415(l) and 419A(d)(2) of the IRC.

       (c)  In the event a Participant herein also participates in any stock
            bonus plan maintained by the Company or a member of a controlled
            group (as defined in Section 14.02) the maximum annual addition
            computed pursuant to subsection (a) hereof may be reduced (except as
            IRC Section 415(c)(6) may apply) by the amount of employer
            contributions and forfeitures allocated to the Participant in such
            other plan; provided, that if the Participant also participates in
            another profit sharing plan, then the maximum annual addition
            hereunder may be reduced prior to the maximum annual addition under
            such plan; employee contributions made by the Participant to such
            other plans

                                                                   Page 72 of 92


            shall be included in computing his annual addition pursuant to
            subsection (b)(ii) hereof; and compensation received from a member
            of a controlled group shall be included in total compensation.

       (d)  In the event a Participant herein is a Participant at any time in a
            defined benefit plan maintained by the Company or a member of a
            controlled group, the sum of the defined benefit plan fraction and
            the defined contribution plan fraction for any Plan Year shall not
            exceed 1.0 but such limitation may be applied to first reduce
            benefits under the defined benefit before being applied to reduce
            benefits under this Plan. For this purpose the defined benefit plan
            fraction for any Plan Year is:

                   Projected annual benefit of the Participant under
                   the plan (determined as of the close of the year)
                   --------------------------------------------------

                   Lesser of:  (a) 1.25 multiplied by the dollar 
                   limitation in effect for such year ($90,000 for 
                   Plan Year beginning in 1983) or (b) 1.4 multiplied 
                   by the percentage limitation with respect to such 
                   individual under the plan for such year (100% of 
                   his average total compensation for his high 3 
                   Years).

            The defined contribution plan fraction for any Plan Year  is:

                   Sum of the annual additions to the Participant's
                   account as of the close of the year
                   --------------------------------------------------

                   Sum of the lesser of the following amounts 
                   determined for such year and for each prior year 
                   of service with the employer: (a) 1.25 multiplied 
                   by the dollar limitation in effect for each such 
                   year ($30,000 for Plan Year beginning in 1983) or 
                   (b) 1.4 multiplied by the percentage limitation 
                   with respect to such individual under the Plan for 
                   each such year (25% of his total compensation).

       (e)  At the election of the plan administrator, in determining the
            defined contribution plan fraction under Subsection (d), above, with
            respect to any Plan Year ending after December 31, 1982, the
            denominator of the fraction with respect to each Participant for all
            years ending before January 1, 1983, shall be an amount equal to the
            product of such denominator under the law in effect for the year
            ending in 1982 multiplied by the transition fraction. The transition
            fraction means a fraction whose numerator is 35% of the compensation
            of the Participant for the year ending in 1981 (limited to


                                      103

                                                                   Exhibit 10(f)
                                                                   Page 73 of 92

 
            $51,875) and whose denominator is 25% of such compensation (but not
            more than $41,500).

       (f)  Provided the Plan satisfied the requirements of IRC Section 415 for
            the last year beginning before January 1, 1983, and pursuant to
            regulations prescribed by the Secretary of the Treasury or his
            delegate, the numerator of the defined contribution plan fraction at
            Subsection (d) may be reduced so that the sum of the defined
            contribution plan fraction and the defined benefit plan fraction
            does not exceed 1.0 for such year.

       (g)  In the case of an individual who is a participant before January 1,
            1983, in a defined benefit plan which is in existence on July 1,
            1982, and with respect to which the requirements of Section 415 of
            the IRC have been met for all years, if such individual's current
            accrued benefit under such plan exceeds the limitation of subsection
            (b) of Section 415, then (in the case of such plan) for purposes of
            such IRC Section 415(b), and also for purposes of IRC Section 415(e)
            as provided under Subsections (d) through (f) hereof, the limitation
            of such IRC Section 415(b) with respect to such individual shall be
            equal to such current accrued benefit.  The term "current accrued
            benefit" means the individuals accrued benefit (at the close of the
            last year beginning before January 1, 1983) when expressed as an
            annual benefit (within the meaning of Section 415(b)(2) of the IRC
            as in effect before the amendments made by the Tax Equity and Fiscal
            Responsibility Act of 1982).  For purposes of determining the amount
            of any individuals current accrued benefit, (I) no change in the
            terms and conditions of the plan after July 1, 1982, and (II) no
            cost-of-living adjustment occurring after July 1, 1982, shall be
            taken into account.

       (h)  In the event the amount of the annual addition for a Participant
            exceeds the limitation of this Section 14.06, the Trustees shall
            forthwith reduce the amount of the annual addition to the
            limitations of Section 14.06 by first refunding any contributions of
            the Participant for such Plan Year to the extent includable in the
            computation of the annual addition; second, if necessary, by
            reducing his share of the Company's contribution for such Plan Year,
            the amount of such reduction to be applied as a reduction of the
            Company's contribution for such Plan Year.  Any remaining excess
            contributions, plus forfeitures, shall be reallocated among the
            other Participants.  If after such adjustments there still remains
            an excess, such amounts from such Participants so affected shall be
            held unallocated in a suspense account and all amounts in the
            suspense account shall be allocated and reallocated to Participant's
            accounts (subject to the limitations of Section 415 of the IRC)
            before any contributions by the Company or by the Participants may
            be made for the limitation year during which such suspense accounts
            are in existence.

                                                                   Page 74 of 92


       (i)  In determining under which plan the contributions or other annual
            additions, or benefits, of a Participant should be reduced under
            this Section, the intent is that the order of reduction set forth
            herein in for purposes of guidance only and not obligatory, and that
            such order of reduction as to one Participant may be different from
            another Participant, so as to afford maximum flexibility to the Plan
            in avoiding a violation of the provisions of Section 415 of the IRC.

       (j)  If the Plan satisfied the applicable requirements of Section 415 of
            the IRC as in effect for all years beginning before January 1, 1987,
            an amount shall be subtracted from the numerator of the defined
            contribution plan fraction (not exceeding such numerator) as
            prescribed by the Secretary of the Treasury so that the sum of the
            defined benefit plan fraction and defined contribution plan fraction
            computed under Section 415(e)(1) of the IRC does not exceed 1.0 for
            such year.

       (k)  (i)    Compensation shall include the following items:

                   (A)  The Participant's wages, salaries, fees for professional
                        service and other amounts received for personal services
                        actually rendered in the course of employment with an
                        employer maintaining the plan (including but not limited
                        to, commissions paid salesmen, compensation for services
                        on the basis of a percentage of profits, commissions on
                        insurance premiums, tips and bonuses).

                   (B)  For purposes of the prior sentence, earned income from
                        sources outside the United States.

                   (C)  Amounts described in IRC Sections 104(a)(3), 105(a) and
                        105(h), but only to the extent that these amounts are
                        includable in the gross income of the Employee.

                   (D)  Amounts described in IRC Section 105(d), whether or not
                        these amounts are excludable from the gross income of
                        the Employee under that section.

                   (E)  Amounts paid or reimbursed by the Employer for moving
                        expenses incurred by an Employee, but only to the extent
                        that these amounts are not deductible by the Employee
                        under IRC Section 217.

                   (F)  The value of a non-qualified stock option granted to an
                        Employee by the employer, but only to the extent that
                        the value of the option is includable in the gross
                        income of the Employee for the taxable year in which
                        granted.

                                                                   Page 75 of 92


                   (G)  The amount includable in the gross income of an Employee
                        upon making the election described in IRC Section 83(b).

            (ii)   Compensation shall not include the following items:

                   (A)  Contributions made by the Employer to a plan of deferred
                        compensation to the extent that, before the application
                        of the IRC Section 415 limitations to that plan, the
                        contributions are not includable in the gross income of
                        the employee for the taxable year in which contributed. 
                        In addition, Employer contributions made on behalf of an
                        Employee to a simplified employee pension described in
                        IRC Section 408(k) are not considered as compensation
                        for the taxable year in which contributed to the extent
                        such contributions are deductible by the Employee under
                        IRC Section 219(b)(7).  Additionally, any distributions
                        from a plan of deferred compensation are not considered
                        as compensation for IRC Section 415 purposes, regardless
                        of whether such amounts are includable in the gross
                        income of the Employee when distributed.  However, any
                        amounts received by an Employee pursuant to an unfunded
                        non-qualified plan may be considered as compensation for
                        IRC Section 415 purposes in the year such amounts are
                        includable in the gross income of the Employee.

                   (B)  Amounts realized from the exercise of a nonqualified
                        stock option, or when restricted stock (or property)
                        held by an Employee either becomes freely transferable
                        or is no longer subject to a substantial risk of
                        forfeiture (see IRC Section 83 and the regulations
                        thereunder).

                   (C)  Amounts realized from the sale, exchange or other
                        disposition of stock acquired under a qualified stock
                        option.

                   (D)  Other amounts which receive special tax benefits, such
                        as premiums for group term life insurance (but only to
                        the extent that the premiums are not includable in the
                        gross income of the Employee), or contributions made by
                        an Employer (whether or not under a salary reduction
                        agreement) towards the purchase of an annuity contract
                        described in Section 403(b) (whether or not the
                        contributions are excludable from the gross income of
                        the Employee).

                   extent not set forth in this Section.

                           SECTION 15 - MISCELLANEOUS


 15.01 VALIDITY OF CONTRACTS.  Neither the Companies, the Committee nor the
       Trustee shall be responsible under any circumstances for the validity of
       any annuity contracts issued pursuant to the provisions of this
       Agreement, nor for the failure on the part of any insurer to make any
       payment or to provide for benefits under any such contract issued by it,
       nor for the action of any person or persons which may render such
       contracts null and void or unenforceable, either in whole or in part.

 15.02 RELIANCE ON INFORMATION FURNISHED BY THE COMPANIES.  Any information
       furnished by the Companies to the Committee or Trustee, such as
       Compensation or contributions of Participants, the proper amount of the
       Companies' contribution, the status of individuals as Employees of the
       Companies, or otherwise, and any other information which may be furnished
       by the Companies to the Committee or Trustee, shall be accepted by the
       Committee and Trustee as being true and correct, and the Committee or
       Trustee shall incur no liability in relying on such information.  In no
       event shall the Trustee or Committee have any right to request or demand
       an audit, investigation, or disclosure of the Companies' books or
       records.

 15.03 INABILITY TO PERFORM.  Neither the Companies, the Committee nor the
       Trustee shall be responsible for any inability to perform, or delay in
       performing, any act occasioned by any restriction or provision of any
       annuity contract, or imposed by any insurer, or by any other person, or
       by law, and in the event any such inability or delay shall be so
       occasioned, then that act which can be performed shall be performed by
       the Companies, the Committee, or the Trustee which, in the sole
       discretion of the Committee, most completely carries out the intention
       and purpose of this Trust.  All parties to this Trust or in any way
       interested therein shall be bound by any act so performed under such
       conditions.

 15.04 EXECUTION OF DOCUMENTS.  All parties to this Trust or claiming any
       interest hereunder expressly agree to perform any and all acts, and to
       execute any and all documents and papers which at any time may be
       necessary or desirable for carrying out any of the provisions of this
       Trust.

 15.05 NOTICE OF REQUIRED ACTION.  In any case in which the Companies, the
       Trustee, the Committee or the insurer shall be directed to take any
       action upon the occurrence of any event, they, or any one or more of
       them, shall be under no obligation or liability to take such action
       unless and until notice, proper and satisfactory to them, shall first
       have been received of the occurrence of such event.  For the purposes of
       this Section 15.05, a certificate in writing signed by any officer of Aon
       and delivered to the Trustee, the Committee or the insurer, or a
       certificate in writing from the Trustee to the insurer as to the
       occurrence or happening of any event, shall constitute conclusive
       evidence of such occurrence

       or happening, and the Trustee, the Committee and the insurer,
       respectively, shall be fully protected and discharged from all liability
       whatsoever in accepting and relying on such certificate.  No insurer
       shall be required to go back of any action of the Trustee, and no insurer
       shall be responsible to see that any action of the Trustee is authorized
       by the terms of this Agreement.

 15.06 RELIANCE UPON COMMUNICATION.  Neither the Companies, the Committee, nor
       the Trustee shall incur any liability in acting upon any notice, request,
       signed letter, telegram, or other paper or documents reasonably believed
       by them or any one of them to be genuine and to be signed or sent by the
       proper person.

 15.07 DISCHARGE UPON PAYMENT.  The payment and acceptance of any money or
       property in a settlement of any participation under this Trust shall
       constitute a complete acquittance and discharge of full liability of the
       Trustee with respect to such participation.  An insurer shall be fully
       discharged from any and all liability for any amount paid to the Trustee,
       the Participant, or any Beneficiary, or to any other person or persons in
       accordance with the written directions of the Trustee, and the Trustee
       and the insurer, respectively, shall be under no obligation or duty to
       see to the distribution or further application of any monies so paid.
       Any change made or action taken by the insurer upon the written
       directions of the Trustee shall fully discharge the insurer from all
       liability with respect thereto.

 15.08 INSURER NOT PARTY TO AGREEMENT.  No insurer shall be deemed a party to
       this Agreement for any purpose.

 15.09 DISPOSITION OF SHARE OF MISSING PERSONS.  In the event the Committee is
       unable to make payment of any benefit payable under this Plan because of
       inability to find the person to whom payment is due and such inability
       continues for a period of two years, the benefit shall be forfeited;
       provided, however, if a claim is subsequently made for such benefit by
       the person entitled thereto, such benefit shall be reinstated.  This
       Section 15.09 shall have no application to any payments that an insurer
       is required to make by the terms of its contract to anyone other than the
       Trustee.

 15.10 GENDER AND CASE.  Where used in this Agreement, words in the masculine
       shall be read and construed as in the feminine, and words in the singular
       shall be read and construed as though used in the plural in all cases
       where such constructions would so apply.

 15.11 SECTION TITLE NOT PART OF AGREEMENT.  The section and subsection
       designations and titles are included solely for convenience and shall, in
       no event, be construed to affect or modify any of the provisions of this
       Agreement or be construed as a part thereof.

 15.12 CONSTRUCTION.  It is intended that this Plan and the Trust Agreement
       which is a part thereof shall comply with the provisions of ERISA,
       constitute a qualified

       profit-sharing plan and trust with a cash or deferred arrangement under
       the provisions of Section 401(a) of the IRC and be operated in a manner
       so as not to discriminate in favor of Highly Compensated Employees.
       Accordingly, the provisions of this Plan and the Trust Agreement shall be
       construed and applied in a manner consistent with such intent.  However,
       to the extent not superseded by ERISA, this plan and the Trust Agreement
       which is a part thereof, shall be construed and enforced in accordance
       with the laws of the State of Illinois.

          SECTION 16 - PROVISIONS APPLICABLE IF PLAN BECOMES TOP-HEAVY


 16.01 APPLICABILITY.  The provisions of this Section 16 shall be applicable
       during any Plan Year only if the Plan was a Top-Heavy Plan or was part of
       a Top-Heavy Group on the Determination Date, and in such case shall
       override and supersede all other provisions in this Plan to the contrary;
       provided, that these provisions shall not apply to a Plan which is not
       itself a Top-Heavy Plan and which was included in an Aggregation Group
       under the second sentence of Section 16.02(f); provided further, that, to
       the extent permitted by law, Section 16.06 shall not apply to any
       Employee who has received the minimum benefit for the Plan Year as
       required under the Top-Heavy rules from any defined benefit plan of the
       Company.

 16.02 ADDITIONAL DEFINITIONS:

       (a) Key Employee. The term "Key Employee" shall refer to any Employee
           who, at any time during the Plan Year or any of the four preceding
           Plan years, is

          (i)   an officer of the Company, excluding any Employee whose
                Compensation is less than 150 percent (150%) of the maximum
                dollar limitation in Section 14.06(a)(i),

          (ii)  one of the ten Employees owning (or considered as owning within
                the meaning of Section 318 of the IRC but substituting 5% for
                50% in IRC Section 318(a)(2)(C)] the largest interests in the
                Company; excluding any Employee whose Compensation is less than
                the maximum dollar limitation in Section 14.06(a)(i),

          (iii) a Five Percent Owner of the Company, or

          (iv)  a One Percent Owner of the Company having an annual compensation
                from the Company of more than $150,000.

       The term shall also include beneficiaries of a Key Employee.  For
       purposes of clause (i), no more than 50 Employees (or, if less, the
       greater of 3 or 10% of the Employees) shall be treated as officers, and
       the officers taken into account shall be the officers with the highest
       compensation.  For purposes of clause (ii), if two Employees have the
       same interest in the Company, the Employee having greater annual
       Compensation from the Company shall be treated as having a larger
       interest.  For this purposes of clauses (ii), (iii) and (iv), the
       aggregation rules of subsections (b), (c) and (m) of Section 414 of the
       IRC (pertaining to employees of a controlled group of corporations, of
       partnerships and proprietorships under common control, and of an
       affiliated service group) shall not apply.

           the IRC but substituting 5% for 50% in Section 318(a)(2)(C)] more

           possessing more than one percent of the total combined voting power
           of all stock of the Company.

           meet the discrimination requirements of Section 401(a)(4) of the IRC
           or the minimum participation standards of Section 410 of the IRC. In
           addition, at the option of the Company, it may include any other plan
           of the Company if the Group would continue to meet the requirements
           of Sections 401(a)(4) and 410 of the IRC with such other plan being
           taken into account.

                                                                   Page 82 of 92
 
       (i) Determination Date. The term "Determination Date" shall mean, with
           respect to any Plan Year, the last day of the preceding Plan Year.
           All required valuations shall be made as of the Determination Date.

       (j) Compensation. The term "Compensation" shall mean total compensation
           but shall not include annual compensation in excess of $200,000 (as
           adjusted for cost-of-living increases by the Secretary or his
           delegate at the same time and in the same manner as the dollar amount
           under Section 14.06). Effective January 1, 1989, this Section
           17.02(j) shall no longer apply.

 16.03 SPECIAL RULES.  In determining whether the Plan is a Top-Heavy Plan or
       part of a Top-Heavy Group, the following rules shall apply.

       (a) Except to the extent provided in regulations issued by the Secretary
           of the Treasury, any rollover contribution (or similar transfer)
           initiated by an Employee from a plan not maintained by the Company
           and made after December 31, 1983, to a plan shall not be taken into
           account with respect to the transferee plan.

       (b) if any individual is a Non-Key Employee with respect to the Plan for
           any Plan Year, but such individual was a Key Employee with respect to
           the Plan for any prior Plan Year, any accrued benefit for such
           Employee (and the account of such Employee) shall not be taken into
           account for purposes of Sections 16.02(e) and (g).

       (c) To the extent provided in regulations issued by the Secretary of the
           Treasury, the Top-Heavy rules of this Section shall be applied on the
           basis of any year specified in such regulations in lieu of Plan
           Years.

       (d) In determining present values and account balances under Sections
           16.02(e) and (g), all distributions made with respect to any Employee
           during the 5-year period ending on the Determination Date shall be
           added back and included therein. The preceding sentence shall also
           apply to distributions under a terminated plan which if it had not
           been terminated would have been required to be included in an
           Aggregation Group.

       (e)        In determining the account of any Participant under 16.02(e) 
                  or (g), amounts attributable to deductible employee
                  contributions shall not be considered.

       (f) If any individual has not performed services for any employer
           maintaining this Plan at any time during the 5 year period ending on
           the Determination Date, any accrued benefit for such individual and
           his accounts shall not be taken into account.

                                                                   Page 83 of 92
 
 16.04 PARTICIPANT'S TOP-HEAVY ACCOUNT.  An additional separate account shall be
       established for each Participant to be known as the Participant's Top-
       Heavy Account to which shall be posted his share of Company's
       contributions, forfeitures and net earnings and valuation adjustments for
       each Plan Year to which Section 16 is applicable.  His share of the
       Company's contributions, forfeitures and net earnings and valuation
       adjustments that have been posted to his Company Contribution Account
       pursuant to Section 4.02 for all prior Plan Years shall be transferred to
       his Top-Heavy Account.

 16.05 VESTING WITH RESPECT TO PARTICIPANTS' TOP-HEAVY ACCOUNTS.  In lieu of the
       vesting schedule set forth in Section 9.01(a), a Participant, provided he
       earns at least one Hour of Service after the Plan has become Top-Heavy,
       shall vest in his Top Heavy Account according to the following schedule:

              Completed Years of Service          Non-Forfeitable %

                    Less than 3                          -0-
                         3                               100%

       provided, that a Participant's nonforfeitable (vested) interest in his
       Top-Heavy Account, as regards funds transferred from his Company
       Contribution Account for prior years as set forth in Section 16.04, shall
       not be reduced from his nonforfeitable interest therein under Section
       9.01.

 16.06 MINIMUM CONTRIBUTION FOR NON-KEY EMPLOYEE.  The Company's contribution
       and forfeitures allocated to the Top-Heavy Account for each Plan Year for
       each Non-Key Employee shall not be less than three percent (3%) of his
       compensation as defined at IRC Section 416(c)(2)(A), except that said
       percentage shall not be more than the highest percentage at which Company
       contributions plus forfeitures are made for any Key Employee.  The
       percentage for each Key Employee shall be determined by dividing the
       amount of his share of the Company's contribution plus forfeitures by the
       amount of so much of his Compensation as does not exceed $200,000.  For
       this purpose, all defined contribution plans required to be included in
       an Aggregation Group shall be treated as one plan.  The foregoing
       exception to the three percent (3%) provision shall not apply if the Plan
       is required to be included in an Aggregation Group wherein the Plan
       enables a defined benefit plan required to be included in such Group to
       meet the requirements of Sections 401(a)(4) and 410 of the IRC pertaining
       to discrimination and minimum participation.  The minimum contribution
       rules of this Section 16.06 may be satisfied by taking into account
       Company contributions attributable to a salary reduction or similar
       arrangement.  The allocation provisions contained in Section 4 of this
       Plan shall be modified as may be necessary to comply with the provisions
       of this Section 16.06 and the Company may, but shall not be required to,
       increase Company contributions so no Participant will incur a reduction
       of benefits by reason of the operation of this Section 16.06.

                                                                   Page 84 of 92
 
 16.07 MAXIMUM ANNUAL ADDITION.  The limitations of Section 14.06 shall be
       applied by substituting 1.0 for 1.25 where it appears in Section 14.06(d)
       in the denominators of the defined benefit plan fraction and the defined
       contribution plan fraction.  The preceding sentence shall not apply if

       (a) The minimum contribution requirements of Section 16.06 would be met
           if 4% were substituted for 3%, and

       (b) The Plan would not be a Top-Heavy Plan or part of a Top-Heavy Group
           if 90% were substituted for 60% in Sections 16.02(e) and (g).

       The application of the first sentence of this Section 16-07 shall be
       suspended with respect to any Participant so long as there are no (i)
       Company contributions, forfeitures or voluntary nondeductible
       contributions allocated to such Participant or (ii) accruals for such
       Participant under the defined benefit plan.  If the first sentence of
       this Section 16.07 is applicable, Section 14.06(e) shall be applied by
       substituting $41,500 for $51,875.

 16.08 SIMPLIFIED EMPLOYEE PENSIONS.  For purposes of Section 16, a Simplified
       Employee Pension shall be treated as a defined contribution plan.  At the
       Company's election, the aggregate Company contributions to a Simplified
       Employee Pension may be taken into account in lieu of the aggregate of
       the accounts of the Employees for the purpose of determining whether the
       Plan is a Top-Heavy Plan or is part of a Top-Heavy Group pursuant to
       Section 16.02(e) and (g).

 16.09 CONTRIBUTIONS OR BENEFITS NOT TAKEN INTO ACCOUNT. The Plan must meet the
       requirements of Section 16.05 and Section 16.06 without taking into
       account (i) contributions or benefits under Chapter 2 of the IRC
       (relating to tax on self-employment income); (ii) Chapter 21 of the IRC
       (relating to Federal Insurance Contributions Act; (iii) Title II of the
       Social Security Act; or (iv) any other federal or state law.

                       Aon EMPLOYEE STOCK OWNERSHIP PLAN

     WHEREAS, effective January 1, 1983, Combined International Corporation, a
corporation organized and existing under the laws of the State of Delaware,
adopted the Combined International Corporation Stock Ownership Plan in order to
provide its employees with the opportunity to acquire common stock ownership in
Combined International Corporation under a stock bonus plan which constituted a
tax credit stock ownership plan designed to invest primarily in Employer
Securities and otherwise meeting the requirements of Sections 44G and 409A of
the Internal Revenue Code of 1954; and

     WHEREAS, the Company  previously amended said Plan three times on December
13, 1984; again on December 13, 1984; and on November 15, 1985;

     WHEREAS, the Company has changed its name from Combined International
Corporation to Aon Corporation (sometimes referred to herein as "Aon");

     WHEREAS, the Company previously amended and restated the Plan ("Fourth

purpose of complying with the Tax Reform Act of 1986, to change the Plan to a
qualified employees' stock bonus plan qualified under Section 401(a) of the IRC
and an employee stock ownership plan under Section 4975(e) of the IRC and
Section 407(d) of ERISA for the exclusive benefit of such employees, and to
change the name of this Plan and Trust Agreement to the Aon Employee Stock
Ownership Plan, pursuant to the Company's change of name to Aon Corporation from
Combined International Corporation and subsequently amended such 1989
Restatement twice effective January 1, 1989, and twice January 1, 1993;

     WHEREAS, Aon now wishes to amend and again restate the Plan for the purpose
of complying with the Omnibus Budget Reconciliation Act of 1993 and to make
certain other desirable changes therein;

          NOW, THEREFORE, pursuant to a resolution adopted by the Board of Aon

follows:

                                                                   Exhibit 10(g)
                                                                   Page 8 of 68
                        SECTION 1 - DEFINITION OF TERMS


     Unless the context shall otherwise clearly indicate, the following terms
shall be construed as hereinafter defined:


  1.01  ACQUISITION LOAN shall refer to a loan (or other extension of credit)
        used by the Plan to finance the acquisition of Employer Securities,
        which loan may constitute an extension of credit to the Plan from a
        party in interest (as defined in ERISA), or may be guaranteed by a party
        in interest.  See Section 5.06.

  1.02  AFFILIATE shall refer to a Subsidiary of Aon that has not adopted the
        Plan herein set forth.

  1.03  ANNIVERSARY DATE shall refer to the last day of each Plan Year during
        which this Agreement shall be in force and effect.

  1.04  BENEFICIARIES shall refer to persons designated by the Participant to
        receive his share of any property of the Trust in case of the
        Participant's death.

  1.05  BOARD shall refer to the Board of Directors of Aon or any committee of
        the Board of Directors delegated authority to act for the whole Board in
        respect of matters relating to the Plan.

  1.06  COMMITTEE shall refer to the Committee appointed by the Board pursuant
        to Section 7.01.  The Committee is designated as the administrator, plan
        administrator, and named fiduciary with respect to the administration of
        the Plan (but not with respect to the control, management and investment
        of the assets of the trust) for the purposes of ERISA.

  1.07  COMPANY as used herein shall refer to Aon Corporation (hereinafter
        referred to as "Aon") when applying the provisions of this Plan as its
        stock bonus plan for its Employees.  It shall refer to each "Subsidiary"
        when applying the provisions of this Trust as the stock bonus plan for
        the Employees of such Subsidiary.  The term "Companies" as used herein
        shall refer collectively to Aon and all Subsidiaries and shall be
        applied as though all of such Companies constituted a single employer.

  1.08  COMPENSATION shall refer to the following types of earnings paid to an
        Employee for his service on behalf of the Company subsequent to the date
        he becomes a Participant, determined before excluding any reduction
        described in Sections 3.03 and 3.04 or for cafeteria plans under Section
        125 of the IRC, but excluding any such amounts paid to him in respect to
        employment during which he is not permanently employed within the United
        States or its possessions as set forth in Section 2.01(b):

                                      131

                                                                   Exhibit 10(g)
                                                                   Page 9 of 68

        (a) salary and fixed-based compensation including compensation for
            overtime;

        (b) bonuses paid pursuant to periodic individual performance appraisals
            and formal contractual bonus programs, but excluding other bonus and
            miscellaneous income; and

        (c) net commission, renewal and override compensation (but excluding
            deferred commission payments).

            In addition to other applicable limitations set forth in the Plan,
            and notwithstanding any other provision of the Plan to the contrary,
            for Plan Years beginning on or after January 1, 1994, the annual
            Compensation of each Employee taken into account under the Plan
            shall not exceed the OBRA '93 annual compensation limit.  The OBRA
            '93 annual compensation limit is $150,000, as adjusted by the
            commissioner of the Internal Revenue Service for increases in the
            cost of living in accordance with Section 401(a)(17)(B) of the IRC.
            The cost-of-living adjustment in effect for a calendar year applies
            to any period, not exceeding 12 months, over which compensation is
            determined (determination period) beginning in such calendar year.
            If a determination period consists of fewer than 12 months, the OBRA
            '93 annual compensation limit will be multiplied by a fraction, the
            numerator of which is the number of months in the determination
            period, and the denominator of which is 12.

            For plan years beginning on or after January 1, 1994, any reference
            in this Plan to the limitation under section 401(a)(17) of the IRC
            shall mean the OBRA '93 annual compensation limit set forth in this
            provision.

            If Compensation for any prior determination period is taken into
            account in determining an employee's benefits accruing in the
            current Plan Year, the Compensation for that prior determination
            period is subject to the OBRA '93 annual compensation limit in
            effect for that prior determination period.  For this purpose, for
            determination periods beginning before the first day of the first
            plan year beginning on or after January 1, 1994, the OBRA '93 annual
            compensation limit is $150,000.

  1.09  EFFECTIVE DATE of this Plan as restated shall be January 1, 1994.

  1.10  EMPLOYEE shall refer to all employees of the Companies, except those who
        are

        (a) included in a unit of employees covered by a collective bargaining
            agreement between employee representatives and one or more
            employers, if retirement benefits were the subject of good faith
            bargaining between such employee representatives and such employer
            or employers; or

                                                                   Exhibit 10(g)
                                                                   Page 10 of 68

        (b) Combination, ordinary and regional representatives and managers as
            those terms were defined under the Retirement Plan for Employers of
            the Life Insurance Company of Virginia and Designated Subsidiaries
            and Designated Affiliates.

  1.11  EMPLOYER SECURITIES shall refer to common stock issued by Aon
        Corporation which is readily tradeable on the New York Stock Exchange.

  1.12  ESOP FUND shall refer to all the assets held under this Plan in both the
        Stock Fund and the General Fund.

  1.13  ERISA refers to the Employee Retirement Income Security Act of 1974, as
        from time to time amended.

  1.14  FINANCED SHARES shall mean shares of Employer Securities acquired by the
        Trust with the proceeds of an Acquisition Loan.

  1.15  GENERAL FUND shall refer to the separate fund maintained under this Plan
        consisting of assets other than those Employer Securities which are part
        of the Stock Fund, including cash dividends, stock rights and stock
        warrants received with regard to all Employer Securities in the ESOP
        Fund.  Where the content so indicates, the term shall also refer to the
        assets held in the General Fund.

  1.16  HIGHLY COMPENSATED EMPLOYEE  shall include an employee who received
        compensation in excess of $75,000, received compensation in excess of
        $50,000 and was in the top paid group, or was an officer and received
        compensation greater than $45,000 (all amounts as adjusted for increases
        in the cost of living per Section 14.06), either (i) in the current year
        while a member of the 100 employees paid the greatest compensation or
        (ii) in the preceding year.  The term "compensation" means compensation
        under Section 14.06, and shall include reductions for pay deferral
        amounts under Section 401(k) of the IRC or for cafeteria plans under
        Section 125 of the IRC.  The following rules shall apply.

        (a) FIVE-PERCENT OWNER.  Such term shall also include an employee who
            was a five-percent owner (as defined at Section 16.02(b)) at any
            time during either the preceding year or the current year.

        (b) TOP-PAID GROUP.  The "top-paid group" is the group consisting of the
            top 20 percent of employees ranked on the basis of compensation paid
            during the year.  For purposes of determining the number of
            employees in the top-paid group (but not for purposes of identifying
            the particular employees therein), or the number of officers taken
            into account under Subsection (c), below, there shall be excluded
            those employees who have not completed six months of service;
            employees who normally work either less than 17 1/2 hours per week
            or not more than six months during any year; employees who have not
            attained age 21; and except to the extent provided in

                                                                   Exhibit 10(g)
                                                                   Page 11 of 68

            regulations, employees included in a unit of employees covered by a
            collective bargaining agreement.

        (c) OFFICERS.  The highest paid officer shall always be treated as a
            Highly Compensated Employee; otherwise the number of officers so
            treated shall not exceed the lesser of (i) 50 employees or (ii) the
            greater of three employees or 10 percent of the employees.

        (d) FAMILY MEMBERS.  Any individual who is a member of the family (i.e.,
            the spouse, and lineal ascendants or descendants and their spouses)
            of a Highly Compensated Employee who is either a five-percent owner
            or one of the ten most highly compensated employees shall not be
            considered a separate employee and his (or her) compensation (and
            any applicable contribution or benefit on behalf of such individual)
            shall be treated as if it were paid to (or on behalf of) such Highly
            Compensated Employee. This rule shall apply in determining the
            compensation of (or any contributions or benefits on behalf of) any
            employee for purposes of any Section of the IRC with respect to
            which a Highly Compensated Employee is defined by reference to IRC
            Section 414(q) (the provisions of which are set forth in this
            Section), except as provided in regulations and except in
            determining the portion of the compensation of a Participant which
            is under the integration level for purposes of IRC Section 401 (1).

        (e) FORMER EMPLOYEES.  A former employee shall be treated as a Highly
            Compensated Employee if he was a Highly Compensated Employee either
            (i) when he separated from service or (ii) at any time after
            attaining age 55.

        (f) NONRESIDENT ALIENS.  For purposes of this Section, employees who are
            nonresident aliens and who receive no earned income (within the
            meaning of Section 911(d)(2) of the IRC) from the Company which
            constitutes income from sources within the United States shall not
            be treated as employees.

        (g) SIMPLIFIED METHOD FOR DETERMINING HIGHLY COMPENSATED EMPLOYEES.  If
            an election by the Company under this Subsection applies to any
            year, in determining whether an employee is a Highly Compensated
            Employee for such year the first sentence of this Section shall be
            applied by substituting "$50,000" for "$75,000" and the $50,000 test
            for the top-paid group shall not apply.  Such election shall not
            apply to any year unless at all times during such year, the Company
            maintained significant business activities (and employed employees)
            in at least 2 significantly separate geographic areas, and the
            Company satisfies such other conditions as the Secretary of the
            Treasury may prescribe.

        (h) COORDINATION WITH OTHER PROVISIONS.  Section 14.02 shall be applied
            before the application of this Section 1.16.

        employer"), who, pursuant to an agreement between the recipient employer
        and any other person (the "leasing organization") has performed services
        for the recipient employer (or the recipient employer and related
        persons determined in accordance with Section 414(n) of the IRC) on a
        substantially full-time basis for a period of at least one year, and
        such services are of a type historically performed by employment in the
        business field of the recipient employer. Contributions or benefits
        provided a Leased Employee by the leasing organization which are
        attributable to services performed for the recipient employer shall be
        treated as provided by the recipient employer. A leased employee shall
        not be considered an employee of the recipient employer if:

        (a) such individual is covered by a money purchase pension plan
            providing:

          (i)  a nonintegrated employer contribution rate of at least ten
               percent of compensation, but including amounts contributed
               pursuant to a salary reduction agreement which are excludible
               from the employee's gross income under Section 125, 402(e)(3),
               402(h), or 403(b) of the IRC,

 1.18  HOURS OF SERVICE shall refer to the hours for which an Employee is
       directly or indirectly paid or entitled to payment, for the performance
       of duties or for a period of time during which no duties are performed
       (irrespective of whether the employment relationship has terminated)
       during the applicable computation period and such hours shall include any
       hours for which back pay, irrespective of mitigation of damages, has
       either been awarded or agreed to; provided, however, no more than 501
       Hours of Service shall be credited on account of any single continuous
       period during which an Employee performs no duties (whether or not such
       period occurs in a single computation period).  An Employee who enters
       military service and again becomes actively employed upon separation from
       such service shall be credited with Hours of Service in respect to his
       period of military service only to the extent and for the purposes
       required by federal law governing veterans' reemployment rights.  Hours
       shall not be credited for payments made or due under a plan maintained
       solely for the purpose of complying with applicable workmen's
       compensation, unemployment compensation, or disability insurance laws, or
       for a payment which solely reimburses an Employee for medical or
       medically related expenses incurred by the Employee.  In those instances
       where payroll or other Company records do not reflect the actual

       with 45 Hours of Service for each calendar week that he would be required

       portion of this Section.  This Section shall be applied, in respect to
       payments for reasons other than the performance of duties and in respect
       to crediting of Hours of Service to a particular computation period, in

       work is for Maternity or Paternity Leave and to establish the number of
       days for which there was such an absence.  "Maternity or Paternity Leave"
       shall mean an absence from work by reason of the pregnancy of the

           purpose of determining his eligibility to participate hereunder
           pursuant to Section 2.01; provided, however, that not more than 12

                 SECTION 2 - EMPLOYEES ENTITLED TO PARTICIPATE


 2.01  CONDITIONS OF ELIGIBILITY.  Every Employee shall become a Participant as
       of the first day of the first pay period succeeding the Employee's
       compliance with the following three requirements:

       (a) He must have completed one year of Service and attained the age of
           21. In determining whether or not an Employee has completed the
           required year or years of Service, there shall be disregarded, except
           as provided in the next sentence, Service prior to any break in
           Service equal to or more than the greater of five 1-year Breaks in
           Service or his prior completed years of Service. Once an Employee has
           completed one year of Service, subsequent breaks in Service shall not
           affect the fact that this requirement has been completed;

       (b) He must be employed within the United States or its possessions on a
           permanent basis as determined under Section 2.05; and

       (c) He must sign and deliver to the Committee a Designation of
           Beneficiary in such form as may from time to time be prescribed by
           the Committee.

       The Committee shall notify all Employees who are eligible to participate
       in this Trust and shall provide them with a Designation of Beneficiary.
       Any Employee who does not become a Participant as of the first date on
       which he would otherwise be eligible, because of employment in a foreign
       country under Section 2.05, shall become a Participant as of the first
       day of any succeeding pay period upon compliance with the provisions of
       this Section 2.01.

 2.02  TERMINATION OF EMPLOYMENT.  Any Participant whose employment with the
       Companies is terminated for any reason whatsoever, shall cease to be
       eligible to participate hereunder, except to the extent he or his
       beneficiary shall have the right to receive payments from his individual
       accounts as provided in Section 8 hereof.  Except as provided in Section
       8.04, any Participant whose employment with the Companies is terminated
       shall, in the event of his later reemployment, become a Participant on
       the first day of the next day period.  If a reemployed Employee, by such
       action, again becomes a Participant in the Plan Year his employment
       terminated, and he remains a Participant through the last day of that
       Plan Year, he shall be entitled to share in the Companies' contribution,
       and the forfeitures, for that Plan Year in accordance with Section
       4.02(a).  Any person who has ceased to be a Participant hereunder by
       virtue of termination of his employment and for whom the Trustee
       continues to hold a portion of his account shall continue to share in net
       earnings and valuation adjustments (as provided in Section 8.07 hereof)
       as though he were a Participant.

                                                                   Page 17 of 68
 
 2.03  LEAVE OF ABSENCE. Any Participant obtaining a leave of absence from the
       Company because of illness, disability (except permanent disability,
       provision for which is made in Section 8.02 hereof) or national emergency
       requiring governmental, military, or naval service subsequent to the
       execution of this agreement or for any other reason, shall continue to
       participate in this Trust and shall not be deemed to have his employment
       terminated.  The Companies agree to adopt a uniform policy with reference
       to the granting of leaves of absence.  Such policy shall be applied
       without individual selection or discrimination in all cases involving the
       same, or substantially the same, facts.  The Companies shall provide the
       Committee with all information with reference to leaves of absence.  The
       determination made by or caused to be made by the Companies shall be
       conclusive and binding upon all persons having any interest in the Trust.

 2.04  TRANSFER TO AN AFFILIATE.  If a Participant is transferred to the
       employment of an Affiliate, he shall be deemed to be on leave of absence
       during such time as he is an Employee of the Affiliate.

 2.05  TRANSFER TO A FOREIGN COUNTRY.  The determination of when an Employee is
       employed within the United States on a permanent basis, when a transfer
       from the United States is or becomes permanent, and when a transfer to or
       from the United States is temporary, shall be made by the Company and
       such determination shall be conclusive and binding on all persons having
       any interest in the Trust.  If he is transferred from the United States
       on a temporary basis, he shall be deemed to continue as being employed
       within the United States on a permanent basis until such time as his
       transfer becomes permanent.

 2.06  EMPLOYMENT IN BARGAINING UNIT.  An individual in a bargaining unit who is
       not deemed to be an Employee by reason of Section 1.10 shall not be
       eligible to participate hereunder and shall not be entitled to make
       contributions hereunder.  Notwithstanding the foregoing, his Service in
       such bargaining unit shall be counted for the purpose of determining his
       eligibility to participate pursuant to Section 2.01, and if a Participant
       becomes ineligible to participate hereunder by reason of employment in
       such bargaining unit, his Service in such bargaining unit shall be
       counted for the purpose of determining his nonforfeitable interest under
       Section 9.

 2.07  INELIGIBLE PERSONS.  Notwithstanding the foregoing provisions of this
       Section 2, no portion of the assets of the Plan attributable to (or
       allocable in lieu of) Employer Securities acquired by the Plan in a sale
       to which IRC Section 1042 or IRC Section 2057 applies may accrue (or be
       allocated directly or indirectly under any Plan of the Companies) for the
       benefit of the following persons during the 10-year non-allocation period
       at IRC Section 409(n)(3)(C):

       (b) Any person who is related (within the meaning of Section 267(b) of

           allocation period does not exceed more than five percent of the
           Company securities held by the Plan which are attributable to a sale
           within Section 1042 of the IRC by a person related to such
           descendants, pursuant to Section 409(h)(3)(A) of the IRC, or

       (c) Any person who owns (after application of Section 318 of the IRC
           without regard to the employee trust exception under Section

           class) of outstanding Company stock (within the meaning of Section
           409(1) of the IRC) within the one-year period ending on the date of
           sale.

                           SECTION 3 - CONTRIBUTIONS


 3.01  CONTRIBUTIONS BY COMPANIES.

       (a) AGGREGATE CONTRIBUTION. For the Plan Year ending December 31, 1989,
           and for each Plan Year thereafter, the Companies, in total, shall pay
           to the Trustee the amount set forth below. The aggregate contribution
           of the Companies for Employees shall be an amount equal to the sum of
           (i), and (ii) below, for Participants with 1,000 Hours of Service
           (including annualized service) employed by the Company on the last
           day of the Plan Year.

          (i)   Such amount as may be determined at the discretion of the Board.
                The portion of the contribution made on behalf of each group of
                employees need not be pro rata but may be based upon such factor
                as the Board shall deem relevant, including geographical
                location, job description or earnings, as the Board in its sole
                discretion shall decide; provided, that any such group shall be
                selected in a manner that does not discriminate in favor of
                Highly Compensated Employees.

          (ii)  In addition to the amounts contributed under (i) above, any
                additional amount as may be needed (after taking into account
                dividends under Section 4.06(d)) to provide the Trustees with
                sufficient funds to pay any maturing obligations under
                Acquisition Loans.

          (iii) If contributions under (i) are not pro rata, then allocations,
                contributions, and other calculations (other than forfeitures)
                under the Plan may be adjusted to take this factor into account.

       (b) ALLOCATION AND POSSIBLE REDUCTION OF AGGREGATE CONTRIBUTION. Each of
           the Companies' share of the aggregate contribution describes in
           Section 3.01(a) shall be equal to the amount of such contribution as
           will be allocated to the individual accounts of Participants who are
           employed by it pursuant to Section 4.02 (a). If, during any Plan
           Year, any Participant is employed by more than one Company that has
           adopted this Plan, the amount allocable to such Participant's account
           may be allocated among such Companies in the proportion of
           Compensation paid by each during the Plan Year in respect to which
           the contribution is made. The Trustee shall be under no duty or
           obligation to inquire into the correctness of the amount of the
           contribution nor shall the Trustee be obligated to institute any
           legal action to compel the Company to make any contribution.

 3.02  DATE OF CONTRIBUTION.  For the purposes of this Agreement, the date of
       any contribution will be deemed to be the last day of the Plan Year for
       which the contribution is made, even though received by the Trustee at a
       later or earlier date.

                     SECTION 4 - ALLOCATION OF TRUST FUNDS


 4.01  ESOP ACCOUNT.  The Committee shall maintain a separate account in the
       name of each Participant to be known as the Participant's "ESOP Account."
       A Participant's ESOP Account shall consist of the sum of two sub-
       accounts, his "Stock Sub-Account" under Section 4.02 and his "General
       Sub-Account" under Section 4.03.

 4.02  STOCK SUB-ACCOUNT.  The Committee shall maintain a separate sub-account
       in the name of each Participant, to be known as his "Stock Sub-Account."
       The Committee shall post to such sub-account for each Participant the
       following:

       (a) For each Participant who has earned 1,000 Hours of Service (including
           annualized service) for the Plan Year and who is employed by the
           Company on the last day of such Plan Year, his share of Employer
           Securities contributed, acquired or released under Sections 3.01 and
           3.03 and forfeitures from the Stock Sub-Accounts. The Stock Sub-
           Account of each Participant whose Compensation is taken into account
           under Section 3.01 in figuring the amount of the contribution by the
           Company shall receive a portion of such Employer Securities in
           proportion to the ratio of the Compensation of the Participant for
           the Plan Year to the aggregate Compensation of all Participants. For
           these purposes, Compensation shall mean Compensation earned during
           periods of Plan participation. Such share shall include fractional
           shares, calculated based upon using four(4) decimal places.

       (b) As of each Valuation Date any additions or deductions arising out of
           net earnings and valuation adjustments resulting from the operation
           of Section 8.07 of this Trust Agreement.

       (c) As of each Valuation Date, any additions arising out of transfers of
           Employer Securities from the General Fund resulting from the
           operation of Section 5.05 of this Trust Agreement.

       (d) Any withdrawals or other payments chargeable to such sub-account.

       (e) As of each Valuation Date, each Participant's share of Employer
           Securities released pursuant to payment of Acquisition Loans from
           dividends under Section 4.06 and from Company contributions and
           earnings thereon in the General Fund; provided, however, that
           Employer Securities released per application of dividends shall be
           allocated as provided under Section 4.06 and shares released per
           application of prior Company contributions and earnings thereon shall
           be accounted for as provided in the formula at Section 5.05.

                                                                   Page 22 of 68

  4.03 GENERAL SUB-ACCOUNT. The Committee shall also maintain a separate sub-
       account in the name of each Participant, to be known as his "General Sub-
       Account," and the Committee shall post to such sub-account of each
       Participant the following:

       (a) For each Participant who has earned 1,000 Hours of Service (including
           annualized service) for the Plan Year and who is employed by the
           Company on the last day of such Plan Year, his share of any cash
           contribution not used to acquire Employer Securities under Section
           3.03 prior to allocation hereunder. Such contribution and forfeitures
           from the General Sub-Accounts shall be allocated among the
           Participants in the same manner as Employer Securities under Section
           4.02(a).

       (b) As of each Valuation Date, any additions or deductions arising out of
           net earnings and valuation adjustments resulting from the operation
           of Section 8.07 of this Trust Agreement.

       (c) As of each Valuation Date, any deductions arising out of transfers of
           Employer Securities to the Stock Fund resulting from the operation of
           Section 5.05 of this Trust Agreement.

       (d) Any withdrawals or other payments chargeable to such sub-account.

 4.04  RECORDS AND ACCOUNTING.  Books of account, forms, and accounting methods
       used in the administration of the ESOP Fund shall be subject in all
       respects to the supervision of the Committee, and if at any time the
       Committee shall determine that the accounting methods are not fair and
       equitable to all Participants, the Committee shall have the right to make
       whatever adjustments are necessary in the accounting methods to carry out
       this Agreement.  Employer Securities shall be accounted for separately
       from other contributions to the Trust.  In the event an erroneous amount
       is posted to a Participant's account for any year, the Committee may, at
       the time such error is discovered, correct such error by making such
       adjustments in allocating contributions, forfeitures and earning and
       valuation adjustments as they may deem fair and equitable, without the
       necessity of making retroactive adjustments in the accounts of
       Participants.  The Committee shall furnish each Participant a record of
       his account which shall include the number of Employer Securities,
       including fractional shares, allocated to his Stock Sub-Account.

 4.05  DESIGNATION OF BENEFICIARY.

       (a) Each Participant shall have the right to designate the Beneficiary or
           Beneficiaries who are entitled to receive any amount or benefit in
           case of the Participant's death and shall have the right at any time
           prior to final distribution of his accounts to change the Beneficiary
           of Beneficiaries theretofore designated by him by filing a new
           designation; provided, however, that such Beneficiary shall be deemed
           to be the surviving spouse of such

                                      145
<PAGE>
                                                                   Exhibit 10(g)
                                                                   Page 23 of 68
 

           Participant unless a spousal consent under Subsection 4.05(b) has
           been signed by the surviving spouse. Each such new designation shall
           completely revoke all designations previously filed by the same
           Participant. All designations shall be in writing and filed with the
           Committee and may be included in the Designation of Beneficiary, or
           in such other form or forms as the Committee shall require. The
           Trustee, at the discretion of the Committee, shall make settlement
           hereunder at the time of the Participant's death with such
           Beneficiary of Beneficiaries as shall be designated by said
           Participant.

       (b) Any designation of a Beneficiary other than his spouse by the
           Participant shall not take effect unless the spouse consents to such
           designation. Such consent must acknowledge the effect of such
           designation, shall be a consent to a specific Beneficiary and to a
           specific form of benefit, and be witnessed by a Plan representative
           or a notary public. Any consent shall be effective only as to such
           spouse. Such designation of a Beneficiary shall take effect without
           the spousal consent only if it is established to the satisfaction of
           a Plan representative that the consent may not be obtained because
           there is no spouse, because the spouse cannot be located, or because
           of such other circumstances as the Secretary of the Treasury may by
           regulations prescribe.

 4.06  ALLOCATIONS OF DIVIDENDS ON EMPLOYER SECURITIES.

       (a) CASH DIVIDENDS. Except as provided in Subsection (d), dividends
           received from the Company in cash shall be deposited in the General
           Fund and credited to the General Sub-Accounts of the Participants to
           the extent applicable to the share allocated to their respective
           Stock Sub-Accounts, and, to the extent applicable to shares held in
           the General Fund or the Financed Shares held in the suspense account
           in the Stock Fund, such dividends shall be credited as income of the
           General Fund.

       (b) STOCK DIVIDENDS. Stock dividends attributable to Employer Securities
           held in the General Fund or in the suspense account in the Stock Fund
           shall be deposited in the General Fund and credited as income of the
           General Fund. Stock dividends attributable to Employer Securities
           held in the Stock Fund and allocated to the Participants' Stock Sub-
           Accounts shall be deposited in the Stock Fund and allocated to the
           Participants' Stock Sub-Accounts in proportion to the shares held in
           each Sub-Account.

       (c) DISTRIBUTION TO PARTICIPANTS. Any cash dividends received by the Plan
           on shares of Employer Securities allocated to Participants' Stock 
           Sub-Accounts may be paid currently (or within ninety (90) days after
           the close of the Plan Year in which paid) in cash to such
           Participants (who are still employees) or their Beneficiaries on a
           nondiscriminatory basis, as determined by the Trustees. Such
           distribution of cash dividends to Participants may be limited to
           shares of Employer Securities which are then vested (under Section 9)
           or

                                      146

                                                                   Page 24 to 68
 

           may be applicable to all shares allocated to their respective Stock
           Sub-Accounts, as determined by the Committee.

       (d) LOAN PAYMENTS. Dividends may be used to make payments on Acquisition
           Loans, at the discretion of the Company, to the extent that a
           deduction is allowable therefor under Section 404(k) of the IRC as
           amended from time to time. Financed Shares in the suspense account
           which are released pursuant to dividends on Employer Securities being
           used to make payments on Acquisition Loans shall be allocated as
           follows:

           (i)   For dividends on allocated Employer Securities in the Stock
                 Fund, an amount of released shares equal in fair market value
                 to the amount of such dividends shall be allocated to the
                 respective Stock Sub-Accounts of those Participants upon whose
                 allocated shares the dividends were paid.

           (ii)  For dividends on unallocated Employer Securities in the
                 suspense account, the released shares shall be allocated to the
                 Stock Sub-Accounts of Participants pursuant to their relative
                 Compensation in the same manner as under Section 4.02(a).

           (iii) For dividends on Employer Securities in the General Fund, the
                 released shares shall be allocated in the same manner as under
                 Paragraph (i).

           (iv)  Released shares under Paragraph (i), to the extent they exceed
                 the amount of such dividends in fair market value, shall be
                 allocated as under Paragraph (ii); provided, however, that if
                 such shares are less in fair market value than the amount of
                 the dividends on allocated Employer Securities used to make
                 payments on Acquisition Loans, the balance of the released
                 shares allocable to the Stock Fund under Paragraph (i) shall be
                 allocated first from shares released under Paragraph (ii) and
                 then if necessary under Paragraph (iii). Any remaining shares
                 needed in order to comply with Paragraph (i) shall be acquired
                 with assets in the General Fund.

           (v)   Shares released due to payments on Acquisition Loans financed
                 by dividends under Paragraphs (ii) and (iii) declared during
                 the first six months of the Plan Year shall be allocated to the
                 Stock Sub-Accounts of Participants employed by the Company on
                 the last day of the prior Plan Year. Shares released due to
                 payments on Acquisition Loans financed by other dividends under
                 Paragraphs (i), (ii) and (iii) declared during the Plan Year
                 shall be allocated to the Stock Sub-Accounts of Participants
                 employed by the Company on the last day of the current Plan
                 Year.

 4.07  ALLOCATION OF FINANCED SHARES.  Financed Shares shall initially be
       credited to a suspense account in the Stock Fund and shall be allocated
       to the Stock Sub-Accounts of Participants only as released upon payment
       of Acquisition Loans.  The number of Financed Shares to be released for
       each Plan Year shall be based upon a ratio approved in regulations and
       rulings issued by the Secretary of the Treasury or his delegate.  The
       shares so released shall be allocated to the Participants' Stock Sub-
       Accounts as provided at Sections 4.02(a), 4.06(d) and 5.05.

 4.08  ALLOCATION OF PURCHASED EMPLOYER SECURITIES OTHER THAN FINANCED SHARES.
       The Trustees may purchase Employer Securities using funds of the General
       Fund in which case such shall be considered an investment of the General
       Fund.  The Trustees from time to time may, at their discretion, allocate
       some or all of the shares of Employer Securities held in the General Fund
       to the Participants.  In the event of any such allocation, the shares so
       allocated shall be transferred from the General Fund to the Stock Fund
       and allocated to the Participants' Stock Sub-Accounts in proportion to
       their respective General Sub-Account balances at the time.

 4.09  DETERMINATION OF COMPENSATION.  The Company shall furnish to the Trustees
       information as to the Compensation of a Participant for each Plan Year,
       and, for the purposes of this agreement, the Trustees shall accept such
       information furnished by the Company as correct, and the amount of the
       Compensation as so certified to the Trustees by the Company shall be
       binding and conclusive on all persons whomsoever, unless a Participant
       files a written objection with the Trustees to the Compensation so
       certified within thirty (30) days from the date he has been notified
       thereof.

                                                                   Page 26 of 68

                            SECTION 5 - INVESTMENTS

 5.01  PRIMARY PURPOSE.  This Plan is designed to invest primarily in Employer
       Securities under Sections 4975(e) of the IRC and Section 407(d) of ERISA.
       Investment by the Trustees of the Stock Fund and of the General Fund
       shall be made pursuant to such primary purpose set forth in the preceding
       sentence; provided, that all investments shall comply with Section 404 of
       ERISA.

 5.02  INVESTMENT OF THE STOCK FUND.  The assets of the Stock Fund shall be
       invested solely in Employer Securities, including stock dividends and
       stock splits on such Employer Securities.  Employer Securities in the
       Stock Fund shall not be sold except to provide funds for Participants
       receiving a cash distribution under Section 8.09(b) and (c).  The Trustee
       shall have full power and authority to receive, collect, receipt for,
       manage, and care for all Employer Securities in the Stock Fund as a
       single fund.  Any other assets transferred to the Plan, including items
       received with regard to Employer Securities such as cash dividends and
       stock rights, shall be held in the General Fund.

 5.03  INVESTMENT OF THE GENERAL FUND.  The Trustee shall have full power and
       authority to receive, collect, receipt for, hold, manage, and care for
       all amounts held, paid and contributed to the General Fund, and the
       proceeds thereof and the income and profits therefrom, as a single fund,
       and to invest and reinvest the same or any part thereof in bonds, notes,
       conditional sales contracts, debentures, stocks, obligations of the
       United States and any other security or interest in income-producing
       property   as the Trustee may deem advisable.  Employer Securities
       acquired by the General Fund shall not be allocated among the accounts of
       the Participants but shall be accounted for like any other asset of the
       General Fund.  The Trustee is further authorized and empowered to sell,
       exchange, convert, or transfer any property of the Trust; to sell covered
       stock options; to retain uninvested for such time as the Trustee deems
       for the best interest of the Trust any cash held in the Trust not
       otherwise required to be invested in Employer Securities, to exercise or
       dispose of all rights accruing to the holders of any securities; to join
       in, by deposit, pledge, or otherwise, any plan of reorganization or other
       means of protecting and dealing with securities; and to compromise,
       adjust, and settle, all claims of or against said Trust at such amounts
       and upon such terms as they deem advisable.

 5.04  INVESTMENTS NOT ALLOCATED TO SEPARATE ACCOUNTS.  Except as provided in
       Section 7.11, all right, title and interest in and to the assets and
       investments of the Trust shall be vested in, and reside exclusively in,
       the Trustee, and no Participant shall have any right, title, or interest
       in or to the assets or investments of the Trust except to have the same
       held, invested, and applied in accordance with the provisions of this
       agreement.  The maintenance of a separate account for each Participant,
       as heretofore provided, shall not require the allocation of or

                                                                   Exhibit 10(g)
                                                                   Page 27 of 68

 
       segregation of assets to each such account, but the creation of such
       accounts is primarily for accounting purposes.

 5.05  PURCHASE OR SALE OF CONTRIBUTED EMPLOYER SECURITIES.  The Trustee may
       acquire or sell Employer Securities with funds in the General Fund.  Such
       transactions may be entered into so as to acquire Employer Securities to
       be distributed to a retired or terminated Participant who decides to take
       stock or because of needed liquidity, or for any other reason in the
       discretion of the Trustee.  Also at the discretion of the Trustee, at
       appropriate intervals all or a portion of the Employer Securities in the
       General Fund may be transferred to the Stock Fund and shall thereafter be
       accounted for as part of the Stock Fund.  Upon any transfer of Employer
       Securities from the General Fund to the Stock Fund, the General Fund
       shall be charged with the Value of such Employer Securities as of the
       relevant Valuation Date, and each Participant's General Sub-Account shall
       bear a portion of such charge based upon his balance in his General Sub-
       Account compared to the total balance in the General Fund; each
       Participant's Stock Sub-Account shall then be credited with the same
       amount as was charged against his General Sub-Account, and such credit
       shall determine the number of shares (or fractional shares) to be
       allocated to his Stock Sub-Account.  The Trustee may sell Employer
       Securities in the Stock Fund only as provided in the following sentence.
       If a cash distribution is made to a retired or terminated Participant or
       to a Beneficiary pursuant to Section 8.09(b) and (c), the Employer
       Securities allocated to his Stock Sub-Account may be sold by the Trustees
       or may be instead transferred to the General Fund to be accounted for
       thereafter like any other asset of the General Fund.  If such individual
       demands Employer Securities and a stock distribution is made to him
       pursuant to Section 8.09(d), then any Employer Securities distributed in
       addition to the number of shares in the Participant's Stock Sub-Account
       shall be taken from Employer Securities held in the General Fund.

 5.06  ACQUISITION LOANS.  The Trustee may incur Acquisition Loans from time to
       time to finance the acquisition of Employer Securities (Financed Shares)
       for the Plan or to repay a prior Acquisition Loan.  An installment
       obligation incurred in connection with the purchase of Employer
       Securities shall constitute an Acquisition Loan.  An Acquisition Loan
       shall be for a specific term, shall bear a reasonable rate of interest
       and shall not be payable on demand except in the event of default.  The
       terms of the loan, whether or not between independent parties, must, at
       the same time the loan is made, be at least as favorable to the Plan as
       the terms of a comparable loan resulting from arm's-length negotiations
       between independent parties.  An Acquisition Loan may be secured by a
       collateral pledge of the Financed Shares so acquired.  No other Plan
       assets may be pledged as collateral for an Acquisition Loan, and no
       lender shall have recourse against Plan assets other than any Financed
       Shares remaining subject to pledge.  In the event of a default, the value
       of the Plan assets transferred in satisfaction of the loan must not
       exceed the amount of default.  Any pledge of Financed Shares must provide
       for the release of shares so pledged as payments on the Acquisition Loan
       are made by the Trustee and such Financed Shares are

       allocated to Participants' Accounts (as provided in Section 4.07).
       Repayments of principal and interest on any Acquisition Loan shall be
       made by the Trustees only from Company contributions paid in cash to
       enable the Trustees to repay such Loan, from dividends under Section
       4.06(d) and from earnings attributable to such Company's contributions
       and dividends, and from the proceeds of Acquisition Loans.


 5.07  DIVERSIFICATION OF INVESTMENTS BY QUALIFIED PARTICIPANTS.

       (a)  Each Qualified Participant may elect within ninety (90) days after
            the close of each Plan Year in his Qualified Election Period to
            direct the Trustees as to the investment of twenty-five percent
            (25%) of his Stock Sub-Account in the Plan, to the extent that such
            portion exceeds the amount to which a prior election under this
            Section applies.  This election shall apply, at the option of the
            Participant, to all funds subject to both the current election and
            to a prior election, and only one election per year shall be
            allowed.

       (b)  The following rules shall apply to this Section:

            (i)    A "Qualified Participant" means any Employee (or former
                   Employee) who has completed at least ten years of
                   participation in the Plan and has attained age 55.

            (ii)   A Participant's "Qualified Election Period" means the six-
                   Plan Year period beginning with the later of (A) the first
                   Plan Year in which the individual became a Qualified
                   Participant or (B) the first Plan Year beginning after
                   December 31, 1986.

            (iii)  In the case of the election year in which the Participant can
                   make his last election, "fifty percent (50%)" shall be
                   substituted for the aforesaid "twenty-five percent (25%)."

            (iv)   The requirements of this Section shall be satisfied if the
                   Participant has the right to demand that the portion of his
                   Accounts covered by the election (or by a prior election) be
                   transferred to a plan qualified under the IRC, to be invested
                   in one or more of three sub-funds, said sub-funds to be
                   differentiated by the investments therein ranging from assets
                   less subject to fluctuations in value and with more stable
                   earnings yield to assets more subject to fluctuations in
                   value and with less stable earnings.

            (v)    Within ninety (90) days after the aforesaid ninety (90)-day
                   election period, the Trustees shall invest the portion of his
                   Company Stock Account covered by the election as directed by
                   the Participant pursuant to his election.

            (vi)   This section shall apply only to Employer Securities acquired
                   after December 31, 1986, and whose value on the Valuation
                   Date immediately preceding the first day on which a Qualified
                   Participant is eligible to make a diversification election is
                   more than $500.

                   SECTION 6 - PROVISIONS RELATING TO TRUSTEE

 6.01  APPOINTMENT OF TRUSTEE AND SUCCESSORS.  There shall at all times be one
       or more Trustees acting hereunder.  Such Trustee or Trustees shall be
       appointed by the Board and the Board has duly appointed the Trustee
       executing this agreement.  The Board shall have the right at any time,
       and from time to time, to remove any Trustee or successor Trustee.  Each
       Trustee or successor Trustee shall serve until such time as he shall
       resign or be removed by the Board and until his successor is appointed.
       In the event of the death, resignation, or removal of any Trustee acting
       hereunder, the Board shall appoint a successor to fill such vacancy and
       such successor Trustee, upon accepting such appointment by an instrument
       in writing delivered to Aon, shall, without further action on his part,
       become vested with all the estate, rights, powers, discretions, and
       duties of his predecessor Trustee with like effect as if originally named
       as Trustee hereunder.  Any Trustee acting hereunder shall have the right
       at any time, by sixty (60) days written notice to Aon, to resign as a
       Trustee hereunder.  By written acceptance of a resignation, Aon may waive
       the 60 day notice.

 6.02  FEES AND EXPENSES OF TRUSTEE.  The Trustee shall be paid such reasonable
       compensation as shall from time to time be agreed upon by Aon and the
       Trustee except that no person so serving shall be entitled to receive
       compensation where he received full-time pay from the Companies.  The
       Trustee, in addition, shall be reimbursed for any reasonable expenses,
       including reasonable counsel fees and investment manager fees, incurred
       by it in the administration of the Trust.

 6.03  PAYMENT OF COSTS, FEES, AND EXPENSES.  Expenses arising form the
       operation of the ESOP Fund, including compensation payable to the
       Trustee, shall be payable from the ESOP Fund.  In construing the
       foregoing, the following shall be understood: (a) expenses incurred in
       connection with transactions involving the purchase or sale of
       investments shall be added to the cost of such investment or deducted
       from the sale price thereof as the case may be; and (b) nothing contained
       herein shall preclude the Companies, by agreement or otherwise, from
       paying expenses not attributable to them hereunder.

 6.04  UNCERTAIN DISTRIBUTION.  In the event any question or dispute shall arise
       as to the proper person or persons to whom any payment shall made, the
       Trustee may withhold such payment until a determination of such question
       or dispute shall have been made, or the Trustee shall have been
       adequately indemnified against loss to its satisfaction.

 6.05  LIABILITY.  No Trustee shall ever be liable for any act or default by any
       predecessor Trustee, nor shall any successor Trustee or Trustees acting
       hereunder be under any duty to examine into or take any action with
       reference to the accounts or any prior Trustee heretofore acting
       hereunder.  All contributions and other monies received by the Trustee
       shall be held for the exclusive benefit of the


                                      153

<PAGE>
                                                                   Exhibit 10(g)
                                                                   Page 31 of 68

 
       Participants and their Beneficiaries and for the payment of such
       administrative expenses as may be provided for hereunder.  The Trustee
       shall be accountable for all such contributions and other monies, but
       shall have no duty to determine that the amounts of the contributions
       comply with the provisions of the Plan.

 6.06  LEGAL ACTION.  The Trustee shall at no time be obliged to institute any
       legal action or to become a party to any legal action unless it shall
       have been indemnified to its satisfaction for any fees, costs, and
       expenses to be incurred in connection therewith.

 6.07  MANNER OF ACTION.  Except as provided for in Section 6.08, if there is
       more than one Trustee, all decisions by the Trustees pertaining to the
       management of the Trust and their duties and powers, shall be made by the
       decision of the majority of the Trustees, and the action of the majority
       of the Trustees shall be binding upon all of the Trustees and have the
       same effect as an action, or decision, of all the Trustees.

 6.08  ALLOCATION OF DUTIES.  If there is more than one Trustee of the Trust,
       one of which may or may not be a bank, they may agree among themselves by
       unanimous consent that one or more (but less than all) of the Trustees
       shall be responsible for performing one or more of the duties and powers
       prescribed to the Trustee under this Agreement.  Such Agreement shall be
       in writing and shall be signed by all of the Trustees, and shall be
       transmitted to the Executive Committee of Aon, who by its action, or by
       action of the Board, may order at any time that such Agreement be
       terminated.  Such Agreement may also be terminated by any one of the
       Trustees giving written notice to the other Trustees that he desires the
       Agreement to be terminated.

 6.09  LIMITATION ON LIABILITY.  To the extent permitted by law, each person
       serving as a Trustee without compensation shall be relieved and released
       from all personal liability by reason of any act or failure to act on his
       part, except to the extent such act or failure to act was a result of
       fraud or gross negligence.

 6.10  INDEMNITY.  Each person serving as a Trustee without compensation (and
       their respective assigns, heirs, executors and administrators) shall be
       entitled to be indemnified by Aon against all costs and expenses
       reasonably incurred by or imposed upon him in connection with or
       resulting from any action, suit or proceeding or threat thereof, to which
       he may be made a party by reason of his serving as a Trustee, except in
       relation to matters as to which a recovery shall be had against him by
       reason of his having been finally adjudged in such action, suit or
       proceeding to have committed a fraudulent act or omission.  The foregoing
       right to indemnity shall include reimbursement of the costs and expenses
       paid in settling any such action, suit or proceeding or threat thereof
       when if appears to Aon that the Trustee did not commit a fraudulent act
       or omission.

                                                                   Page 32 of 68


 6.11  DISBURSEMENTS.  The Trustee shall make such disbursements or payments
       from the ESOP Fund as may be directed by the Committee.  Any such
       directions shall be in writing and signed by a member of the Committee or
       the Secretary of the Committee.  The Trustee shall have no duty or
       obligation to inquire into the propriety of any payment directed by the
       Committee but may conclusively presume that the payment is authorized by
       the terms of the Plan; however, this Section shall in no event be
       construed as granting the Committee any authority to manage, control, or
       invest the assets of the Trust but is intended solely to facilitate the
       administration of the Plan by the Committee.

 6.12  REPORTS.  The Trustee shall maintain accurate and detailed records and
       accounts of all investments, receipts, disbursements and other
       transactions hereunder, and all accounts, books and records relating
       thereto shall be open at all reasonable times to inspection and audit by
       any person or persons designated by Aon or the Committee.  Within sixty
       (60) days following the close of each Plan Year (or following the close
       of such other periods as may be agreed upon by the Trustee and Aon) the
       Trustee shall file with Aon a written account setting forth a description
       of all Employer Securities and other property purchased and sold, all
       receipts, disbursements and other transactions affected by it during such
       period, and listing the Employer Securities and other property held by it
       at the end of such period, at their cost and fair market values.  Aon may
       approve such accounting by written notice of approval delivered to the
       Trustee or by failure to express objection to such accounting in writing
       delivered to the Trustees within eight (8) months from the date upon
       which the accounting was delivered to Aon.  Upon receipt of a written
       approval of the accounting, or upon the passage of said period of time
       within which objections may be filed, without written objections having
       been delivered to the Trustee, such accounting shall be deemed to be
       approved, and the Trustee shall be released and discharged as to all
       items, matters and things set forth in such accounting as if such
       accounting had been settled and allowed by a decree of a court of
       competent jurisdiction in any action or proceeding in which the Trustee,
       Aon, and all persons having or claiming to have any interest in the Trust
       Fund or under the Plan, were parties.  The Trustee, nevertheless, shall
       have the right to have its accounts settled by judicial proceedings if it
       so elects, in which event only the Trustee and Aon shall be necessary
       parties.  Nothing contained in this paragraph shall relieve the Trustee
       from any responsibility or duty under ERISA and any subsequent amendment
       thereto.

 6.13  ADDITIONAL POWERS OF TRUSTEE.  The Trustee shall have exclusive authority
       and discretion to manage and control the Trust Fund which shall
       constitute all of the assets of the Plan.  Pursuant thereto, and in
       addition to the other powers granted by this Agreement, the Trustee shall
       be authorized and empowered:

       (a)  To sell, exchange, transfer, or otherwise dispose of any property
            held by it, by private contract or at public auction, and no person
            dealing with the Trustee shall be bound to see the application of
            the purchase money or to

                                                                   Page 33 of 68


            inquire into the validity, expediency, or propriety of any such sale
            or other disposition;

       (b)  To make, execute, acknowledge, and deliver any and all documents of
            transfer and any and all other instruments that may be necessary or
            appropriate to carry out the powers herein granted;

       (c)  To register any investment held for either Fund in its own name or
            in the name of a nominee and to hold any investment in bearer form,
            but the books and records of the Trustee shall at all times show
            that all such investments are part of the Trust Fund;

       (d)  To manage, administer, operate, lease for any number of years,
            develop, improve, repair, alter, demolish, mortgage, pledge, grant
            options with respect to, or other wise deal with any real property
            or interest therein at any time held by it;

       (e)  To employ suitable agents and persons to render it services and
            advice in connection with its responsibilities and to pay their
            reasonable expenses and compensation;

       (f)  To settle, compromise, or submit to arbitration, any claims, debts,
            or damages, due or owing to or from the Trust, to commence or defend
            suits or legal proceedings and to represent the Trust in all suits
            or legal proceedings;

       (g)  To enter into any covenants or agreements binding the Trust with
            regard to any securities or other property held by it as Trustee;
            and

       (h)  To borrow or raise monies for the purposes of the Trust and for any
            such so borrowed to issue its promissory note as Trustee and to
            secure the repayment thereof by pledging all or any part of the
            assets of the Trust, but nothing herein contained shall obligate the
            Trustee to render itself liable individually for the amount of any
            such borrowing; and no person loaning money to the Trustee shall be
            bound to see to the application of the money loaned or to inquire
            into the validity , expediency, or propriety of any such borrowing.

 6.14  INVESTMENT MANAGER.  The Trustees are hereby expressly authorized, in
       their discretion, to delegate the investment powers granted to them by
       this agreement to an investment manager provided such investment manager
       meets all the requirements set forth in Section 3(38) of ERISA.  In the
       event of the delegation of their investment powers as above provided, the
       Trustees shall have no duty or obligation to supervise or control in any
       way the investments made and shall in no way be liable or responsible on
       account of any investments made or retained by the investment manager,
       whether or not such investments are authorized by this agreement, or for
       any acts or omissions of the investment manager.

                     SECTION 7 - ADMINISTRATION OF THE PLAN


 7.01  COMMITTEE.  The Board shall appoint a Committee consisting of not less
       than three (3) nor more than seven (7) members.  Any person appointed a
       member of the Committee shall signify his acceptance by filing written
       acceptance with the Board.  The members of the Committee shall serve
       without compensation for their services.  The term of the members of the
       Committee shall commence with the date of their appointment and continue
       at the convenience of the Board.  Any member of the Committee may resign
       by delivering his written resignation to the Company, and such
       resignation shall become effective at delivery or at any later date
       specified therein.

 7.02  DUTIES OF COMMITTEE.  The Committee shall have those duties prescribed to
       it elsewhere in this Agreement, and shall be responsible for the general
       administration of the Plan except where duties in connection with such
       general administration have been prescribed to others under this
       Agreement.  The Committee shall not incur expenses on behalf of the Plan
       or Trust except with the consent of Aon.

 7.03  CHAIRMAN AND SECRETARY.  The members of the Committee shall elect a
       chairman from their number, and a secretary who may be but need not be
       one of the members of the Committee.

 7.04  MEETINGS AND QUORUM.  The Committee shall hold meetings upon such notice,
       at such place or places, and at such time or times as it may from time to
       time determine.  A majority of the members of the Committee at the time
       in office shall constitute a quorum for the transaction of business.  All
       resolutions or other actions taken by the Committee at any meeting shall
       be by the vote of a majority of the members of the Committee present at
       the meeting.  Actions may be taken by the Committee without a meeting
       where such actions are consented to in writing by the entire Committee.

 7.05  ALLOCATION OF DUTIES.  The Committee, by its action, may allocate its
       fiduciary responsibilities among its members, and may designate persons
       other than its members to carry out its fiduciary responsibilities.  The
       Committee, individual members of the Committee allocated specific
       fiduciary responsibilities, and persons other than members of the
       Committee designated to carry out specific fiduciary responsibilities,
       may employ one or more persons to render advice with respect to their
       responsibilities.  If the Committee has allocated a specific fiduciary
       responsibility among its members, or has designated persons other than
       its members to carry out a specific fiduciary responsibility, it shall do
       the following things: (a) it shall make as a condition of such allocation
       or designation the fact that the Committee may terminate the allocation
       or designation at will; and (b) it shall report such allocation or
       designation to the Executive Committee of Aon

                                                                   Page 35 of 68

 7.06  AON.  Aon shall have the responsibility for hiring personnel in
       connection with the administration of the Plan (who shall be employees of
       Aon), and persons to perform services in connection with the
       administration of the Plan on an ad hoc basis, as may be required to

       establish rules and procedures for administration of the Plan not
       inconsistent with the Plan's provisions, and administer the Plan in
       accordance with such provisions and such rules and procedures.  The
       Committee shall have the exclusive right and discretionary authority to
       construe the terms and provisions of the Plan, including without
       limitation, the power to construe or interpret disputed, ambiguous or
       uncertain terms, and  such other powers as may be necessary to carry out
       the provisions of the Plan.  The Committee shall also have the
       discretionary authority to determine all questions relating to the
       eligibility of Employees to participate in the benefits of the Plan and
       the amount of such benefits, and resolve all questions pertaining to the
       administration, interpretation and application of the Plan provisions.
       Actions taken in good faith by the Company, the Committee or an Employer
       shall be conclusive and binding on all interested parties as to all
       questions of interpretation and application under this Plan and as to all
       other matters arising out of the administration thereof, and shall be
       given the maximum possible deference allowed by the law.

 7.08  LIMITATIONS ON LIABILITY.  To the extent permitted by law, each member of
       the Committee, and each employee of the Company who is involved in the
       administration of the Plan, shall be relieved and released from all
       personal liability by reasons of any act or failure to act on his part
       with respect to the administration of the Plan, except to the extent such
       act or failure to act was a result of fraud or gross negligence.

 7.09  INDEMNITY.  Each person named in Section 7.08 (and his respective
       assigns, heirs, executors and administrators) shall be entitled to be
       indemnified by Aon against all costs and expenses reasonable incurred by
       or imposed upon him in connection with or resulting from any action, suit
       or proceeding or threat thereof, to which he is made a party by reason of
       his being involved in the administration of the Plan, except in relation
       to matters as to which a recovery shall be had against him by reason of
       his having been finally adjudged in such action, suit or proceeding to
       have committed a fraudulent act or omission.  The foregoing right to
       indemnity shall include reimbursement of the costs and expenses paid in
       settling any such

                                                                   Page 36 of 68
 
       action, suit or proceeding or threat thereof when it appears to Aon that
       the person did not commit a fraudulent act or omission.

 7.10  IDENTITY.  The Committee shall have authority to determine the identity
       of the distributees, and in so doing, to act upon such information as, on
       reasonable inquiry, it may deem reliable with respect to heirship,
       relationship, survivorship, or any other fact relative to the
       distributees; the Committee may rely upon any affidavit, certificate,
       letter, or other paper or document reasonably believed by it to be
       genuine, and upon any evidence reasonably believed by it to be
       sufficient; and shall be protected and saved harmless in all payments
       required to be made hereunder, if made in good faith and without actual
       notice or knowledge of the changed condition or status of any person
       receiving payments upon a condition.

 7.11  VOTING OF EMPLOYER SECURITIES.  Each Participant (or, in the event of the
       Participant's death, the Participant's Beneficiary) shall have the right
       to direct the Trustee as to the manner in which shares of Employer
       Securities allocated to his Stock Sub-Account are to be voted on each
       matter brought before an annual or special stockholders' meeting of the
       Company, and each Participant (or Beneficiary) shall be considered a
       "named fiduciary" under Section 402(a)(2) or ERISA with respect to this
       direction to the Trustee.  Before each such meeting of stockholders, the
       Company  shall cause to be furnished to each Participant (or Beneficiary)
       a copy of the proxy solicitation material, together with a form
       requesting confidential direction as to how the shares of Employer
       Securities allocated to such Participant's Stock Sub-Account are to be
       voted on each matter.  Upon timely receipt of such directions, the
       Trustee shall vote the shares (including fractional shares) of Employer
       Securities allocated to such Participant's Stock Sub-Account on each
       matter as directed by the Participant.  Each Participant (or Beneficiary)
       who timely directs voting of Employer Securities shall also direct the
       vote of a portion of the shares of Employer Securities for which signed
       voting directions are not timely received and any unallocated shares of
       Employer Securities held in a suspense account ("Undirected Shares") in
       the General Fund and in the Stock Fund.  Each Participant (or Beneficiary
       shall be considered a "named fiduciary" under Section 402(a)(2) of ERISA
       with respect to this direction of the Trustee.  Each such Participant
       shall be entitled to direct the voting of that number of the Undirected
       Shares resulting from multiplying the total number of Undirected Shares
       by a fraction, the numerator of which is the total number of shares
       allocated to that Participant's Stock Sub-Account and the denominator of
       which is the total number of shares of all Participants who timely direct
       the voting of Employer Securities.  The Participants' individual
       instructions are to be given to a recordkeeper, auditor, or other person
       who is not the Company, a Subsidiary, or an Employee, officer, or
       director thereof and such person shall not divulge any Participant's
       directions to any person.  Instructions received by the Trustee shall be
       made in the aggregate basis, shall be held by the Trustee in strict
       confidence and shall not be divulged or released to any person except as
       may be required to vote at the shareholders' meeting, or as required by
       applicable law.

  7.12  RIGHTS ON TENDER OR EXCHANGE OFFER.  Each Participant (or in the event
of the Participant's death, his Beneficiary) may direct the Trustee as to how to
respond to a tender or exchange offer with respect to shares of Employer
Securities in his Stock Sub-Account, and each Participant (or Beneficiary) shall
be considered a "named fiduciary" under Section 402(a)(2) of ERISA with respect
to this direction to the Trustee.  The Company shall use its best efforts to
timely distribute or cause to be distributed to each Participant (or
Beneficiary) such information as will be distributed to stockholders of the
Company in connection with any such tender or exchange offer.  Upon timely
receipt of such written instructions, the Trustee shall respond as instructed
with respect to shares of Employer Securities allocated to such Participant's
Stock Sub-Account.  If the Trustee does not receive timely written instructions
from a Participant as to the manner in which to respond to such a tender or
exchange offer, the Trustee shall not tender or exchange any shares of Employer
Securities with respect to which such Participant has the right of direction.
Each Participant (or Beneficiary) shall also be entitled to direct the tender or
exchange of a portion of the unallocated shares of Employer Securities held in a
suspense account in the General Fund and the Stock Fund and each Participant (or
Beneficiary) shall be considered a "named fiduciary" under Section 402(a)(2) of
ERISA with respect to this direction to the Trustee.  Each such Participant
shall be entitled to direct the voting of that number of unallocated shares by a
fraction, the numerator of which is the total number of shares allocated to that
Participant's Stock Sub-Account and the denominator of which is the total number
of shares of Employer Securities which are allocated to the Stock Sub-Accounts
of all Participants for which instructions on the tender or exchange offer are
received.  The Participants' individual instructions shall be given to a
recordkeeper, auditor or other person who is not the Company, a Subsidiary, or
an Employee, officer or director thereof and such person shall not divulge any
Participant's directions to any person, except as required by applicable law.
Instructions received by the Trustee shall be made in the aggregate basis, shall
be held by the Trustee in strict confidence and shall not be divulged or
released to any person except as may be required to vote or tender.

                                                                   Page 38 of 68
 
            SECTION 8 - DISPOSITION OF THE SEPARATE TRUST ACCOUNTS


 8.01  PARTICIPANT STILL EMPLOYED BY COMPANY AFTER RETIREMENT DATE.  A
       Participant shall have a 100% vested interest in his Accounts when he
       attains his Normal Retirement Date.  If he continues in active
       employment, no distribution shall be made to such Participant until he
       retires or is retired from active employment and the Committee is so
       advised, and he shall continue to participate in this Trust.

 8.02  DISPOSITION AT OR AFTER RETIREMENT DATE OR IN CASE OF PHYSICAL OR MENTAL
       DISABILITY.  In the event that at or after his Normal Retirement Date a
       Participant shall resign or be released from employment from the
       Companies, or in the event that the employment of any Participant shall,
       at any time, either before or after Normal Retirement Date, be terminated
       because of permanent physical or mental disability, then the Committee
       shall direct the Trustee to distribute the Participant's entire
       individual accounts to such Participant, without regard to the provisions
       for vesting as set forth in Section 9, in one or more of the ways
       described in Section 8.09.  Permanent physical or mental disability means
       a physical or mental disability of illness which , in the opinion of a
       physician approved by the Committee, renders the Participant permanently
       incapable of performing the duties he was performing for the Companies
       when such disability began.

 8.03  DISPOSITION UPON THE DEATH OF A PARTICIPANT.  The Committee, upon the
       death of a Participant, whether before or after retirement, shall direct
       the Trustee to distribute the Participant's individual accounts, without
       regard to the provisions for vesting as set forth in Section 9, to such
       Participant's Beneficiary in one or more of the ways described in Section
       8.09.  If the Participant has not named a Beneficiary, or if no
       Beneficiary is living at the death of the Participant, such accounts
       shall be paid over in one sum to the executor or administrator of the
       estate of such deceased Participant; provided, however, that if in such
       situations the Participant's spouse survives him then such surviving
       spouse shall be the Beneficiary.  In the event the Beneficiary dies
       subsequent to the death of the Participant but prior to the distribution
       of the entire accounts to the Beneficiary, the balance of the accounts
       shall forthwith be paid over and delivered to the executor or
       administrator of the estate of the deceased Beneficiary.

 8.04  DISPOSITION UPON TERMINATION OF EMPLOYMENT BEFORE REACHING RETIREMENT
       DATE.  If a Participant shall withdraw from the employ of the Companies
       prior to attaining his Normal Retirement Date, whether because of
       resignation or discharge, or any reason other then permanent disability,
       provision for which is made in Section 8.02, the Committee shall direct
       the Trustee to pay such Participant his vested interest in his individual
       accounts, as provided in Section 9, in one or more of the ways described
       in Section 8.09.  If prior to incurring a 1-Year Break in Service such
       terminated Participant shall file with the Committee an application for
       the payment of benefits which has been approved by the

                                                                   Exhibit 10(g)
                                                                   Page 39 of 68
 
       Committee and distributions pursuant thereto have commenced, and if prior
       to incurring such 1-Year Break in Service he shall be reemployed by one
       of the Companies, he shall not share in the Companies' contribution or
       forfeitures for the Plan Year in which the withdrawal occurred (this
       assumes he reentered employment in the same year as the withdrawal
       occurred) and shall not be entitled to have contributions made on his
       behalf under Section 3, in respect to his Compensation for the 12 month
       period following the month in which his application is filed or following
       the month of termination of his employment, whichever shall occur later
       and, accordingly, shall not share in Companies' contributions and
       forfeitures on the basis of the contribution which would otherwise have
       been made on his behalf under Section 3 during this period.

 8.05  TERMINATION OF THE TRUST AND DISPOSITION UPON SUCH TERMINATION. Unless
       otherwise terminated as hereinafter provided in Paragraphs (a), (b), (c)
       or (d) of this Section 8.05, this Trust and Plan shall continue in
       perpetuity or for such time as may be necessary to accomplish the purpose
       for which it is created.  This Trust and Plan shall terminate in respect
       to a Company upon the happening of any of the following events, but shall
       continue as a liquidation trust until final distribution of all assets.

       (a) ELECTION BY AON.  Aon, by appropriate resolutions, by its Board, may
           elect to terminate this Trust and Plan as to any Company or all
           Companies.

       (b) BANKRUPTCY.  In the event a Company at any time shall be adjudicated
           bankrupt or insolvent.

       (c) DISSOLUTION.  In the event a Company at any time shall be legally
           dissolved.

       (d) MERGER OR CONSOLIDATION.  In the event of the merger or consolidation
           of a Company in and with another corporation or an association and
           such other corporation or association shall not agree to continue
           this Trust, with proper agreement with the Trustee and Committee;
           provided, however, in the event of dissolution, merger, or
           consolidation of a Company, provision may be made by the successor or
           successors, whether it be an individual, firm, or corporation, for
           continuing this Trust and Plan, and such successor or successors
           shall be substituted for its predecessor hereunder, in which event
           the Trust and Plan shall continue in full force and effect in respect
           to such successor.

       If this Trust and Plan shall be terminated upon the happening of any of
       the events specified in Paragraphs (a), (b), (c), or (d) of this Section
       8.05, the Committee shall direct the Trustee to distribute the value of
       the affected Participants' entire accounts to such Participants in the
       manner provided in Section 8.09.  Upon the completing of all payments to
       everyone entitled thereto, this Trust and Plan shall finally cease and
       terminate in respect to the Company and Participants affected thereby.
       Upon the termination of the Trust and Plan

                                                                   Exhibit 10(g)
                                                                   Page 40 of 68
 
       in respect to any Company, any unallocated contributions, forfeitures, or
       earnings and valuation adjustments shall be allocated to the accounts of
       the affected Participants in a fair and equitable manner as determined by
       the Committee.  In the event of any action by or in respect to any
       Company resulting in the termination of the Trust and Plan pursuant to
       this Section 8.05, this Trust and Plan shall only terminate in respect to
       such Company but not in respect to any other Companies which have adopted
       the Plan, it being understood that the Trust and Plan shall continue in
       full force and effect as to any such other Companies.

 8.06  PAYMENT TO MINORS, ETC.  In case any payment hereunder becomes payable to
       a minor, person under legal disability, or person who by reason of
       physical or mental disability, although not adjudicated incompetent, is
       in the opinion of the Committee unable to administer properly such
       payment, then the same may be paid out by the Trustee for the benefit of
       such person in any of the following ways as the Committee, in its sole
       and uncontrolled discretion, shall determine:

       (a)  directly to such person; or

       (b) to the legally appointed guardian or conservator of such person; or

       (c) to some near relative of such person for the support, maintenance,
           and education of such person; or

       (d) by the Trustee using such amounts directly for the benefit of such
           person.

       The payment and acceptance of any money or property in settlement of a
       participation under this Section 8.06 shall constitute a complete
       acquittance and discharge of all liability of the Trustee with respect to
       such participation.

 8.07  NET EARNINGS AND VALUATION ADJUSTMENT.  As of each Valuation Date, there
       shall be allocated the net earnings and valuations changes of the ESOP
       Fund for the period ending on such date among the accounts maintained on
       such date on the basis of, and in proportion to, their account balances
       on such date.  A separate adjustment shall be made for the Stock Fund and
       for the General Fund as set forth  below.

       (a) There shall be valued the Employer Securities in the Stock Fund.  The
          resulting Value, which shall be the amount of the Stock Fund and which
          shall not be revised until the next Valuation Date except as described
          in the last sentence of this Subsection, shall then be compared with
          the total amount of all Participants' Stock Sub-Accounts in the Stock
          Fund as of such Valuation Date for the purpose of determining the
          interests of the Participants in the assets of the Stock Fund and the
          value thereof.  If the Value of the Employer Securities shall be more
          or less than the total amount of all Participants' Stock Sub-Account
          balances, then the Trustees shall prorate any such difference and
          shall add or deduct from each Stock Sub-Account such amount

                                                                   Exhibit 10(g)
                                                                   Page 41 of 68
 
          as shall be determined upon the basis of the ratio that the balance of
          each Participant's Stock Sub-Account bears to the total of all
          Participants' Stock Sub-Account balances.  The Value of the Employer
          Securities contributed by the Company as of the last day of each Plan
          Year shall be their Value for purposes of Section 1.31, which shall be
          allocated among those Participants described in Section 4.02(a) on a
          per compensation basis, but for the purpose of valuation adjustments
          shall not be regarded as a part of the Stock Fund or the Stock Sub-
          Account of any Participant until such Employer Securities are remitted
          to the Trustees.

       (b) There shall then be valued or appraised, the assets in the General
           Fund. The resulting value shall be the amount in the General Fund and
           shall not be revised until the next Valuation Date. The amount of
           such valuation shall be allocated among the General Sub-Accounts of
           each Participant's pro rata based upon the balance in each
           Participant's Stock Sub-Account compared to the balance of all
           Participants' Stock Sub-Accounts in the same ratio as the adjustment
           made under the penultimate sentence of Subsection (a), after giving
           effect to such adjustment but prior to giving effect to the
           adjustment under the final sentence of subsection (a).

 8.08  METHOD OF VALUING ASSETS.  Valuation adjustments under Section 8.07 shall
       be based on the fair market value of the assets held by the Trustees and
       the Trustees shall adopt accepted valuation and accounting methods in
       determining fair market value.  The Value of Employer Securities shall be
       determined pursuant to Section 1.31.

 8.09  GENERAL PROVISIONS GOVERNING DISTRIBUTIONS.  Distributions to a
       terminated or retired Participant or Beneficiary of a deceased
       Participant shall be governed by the following:

       (a) Except upon termination of this Trust as provided in Section 8.05,
           and as provided in Subsection (h) distribution shall not be made to a
           Participant until he has retired or has terminated his employment.

       (b) Upon direction of a Participant except as provided in Subsections (h)
           and (i), distribution shall be made in a lump sum as soon as
           administratively feasible following the administrative period
           described in Subsection (f).

       (c) Except as provided in Subsection (d), below, distribution shall be
           made in the form of cash.

       (d) A Participant or Beneficiary shall have the right to demand that his
           benefits be distributed in the form of Employer Securities, and shall
           be advised in writing of his right to demand such form of
           distribution.  Any fractional shares shall be distributed in cash.

       (e) Despite the fact that a Participant has retired or has terminated
           employment, no Employer Security allocated to his Stock Sub-Account
           prior to January 1, 1989 shall be distributed from that account
           before the end of the eighty-fourth (84th) month beginning after the
           month in which the security is allocated to the account, unless such
           retirement or termination of employment constitutes a "separation
           form service" as that phrase is construed under the IRC.

       (f) No distribution in the form of cash under Sub-section (c), above,
           shall be made to a Participant or Beneficiary of a deceased
           Participant, until 30 days have elapsed from the last to occur of the
           date he is advised of his right under Subsection (d) to demand that
           his benefits be distributed in the form of Employer Securities or the
           date of termination of employment. Any demand made by a Participant
           or Beneficiary of a deceased Participant shall be irrevocable. If he
           fails to make such demand during such 30-day period, he shall be
           deemed not to have made any such demand, and payment shall be made in
           accordance with the preceding provisions of this Section in the same
           manner at though no demand had been made. All elections and requests
           shall be made in writing.

       (g) As provided in Section 2.02, no distribution shall be made to a
           terminated Participant who has been re-employed and is again a
           Participant at the time the distribution would otherwise become
           payable.

       (h) Notwithstanding the provisions of Subsection (b) hereof, distribution
           to a Participant who has terminated his service, or who is a 5% owner
           [as defined in Section 16.02(b)] at any time during the 5-Plan-Year
           period ending in the calendar year in which he attains age 70-1/2
           shall commence not later than the 1st day of April of the calendar
           year following the calendar year in which he attains age 70-1/2. If a
           Participant who has not terminated his service subsequently becomes a
           5% owner after the calendar year in which he attains age 70-1/2, then
           distribution shall commence by April 1st of the calendar year
           following the Plan Year during which he became a 5% owner. Effective
           January 1, 1989, distribution to a Participant shall commence by
           April 1st of the calendar year following the calendar year in which
           he attains age 70-1/2, without regard to whether he has terminated
           his service; provided, that this rule shall not apply to a
           Participant age 70-1/2 or over on January 1, 1988 unless he has been
           a 5% owner at any time during the Plan Year ending during the
           calendar year when he attained age 66-1/2 or any subsequent Plan
           Year.

       (j) Distribution to a  Participant (or his Beneficiary) whose vested
           interest in his Accounts has a fair market value of $3,500 or less
           based on the Plan's last valuation shall be made as soon as
           administratively convenient.

       (k) Except as provided in regulations, the provisions of IRC Section
           401(a)(9) are hereby incorporated by reference to the extent not set
           forth in this Section.

 8.10  ELIGIBLE ROLLOVER DISTRIBUTIONS.  Effective with respect to distributions
       made on or after January 1, 1993, a distributee may elect, at the time
       and in the manner prescribed by the plan administrator, to have any
       portion of an Eligible Rollover Distribution paid directly to an Eligible
       Retirement Plan specified by the distributee in a Direct Rollover.  For
       purposes of this Section 8.10:

       (a) An "Eligible Rollover Distribution" is any distribution of all or any
           portion of the balance to the credit of the distributee, except that
           an Eligible Rollover Distribution does not include: any distribution
           that is one of a series of substantially equal periodic payments (not
           less frequently than annually) made for the life (or life expectancy)
           of the distributee and the distributee's designated beneficiary, or
           for a specified period of ten years or more; any distribution to the
           extent such distribution is required under Section 401(a)(9) of the
           Code; and the portion of any distribution that is not includable in
           gross income (determined without regard to the exclusion for net
           unrealized appreciation with respect to employer securities).

       (b) An "Eligible Retirement Plan" is an individual retirement account
           described in Section 408(a) of the Code, an individual retirement
           annuity described in Section 408(b) of the Code, an annuity plan
           described in Section 403(a) of the Code, or a qualified trust
           described in Section 401(a) of the Code, that accepts the
           distributee's Eligible Rollover Distribution. In the case of an
           Eligible Rollover Distribution to the surviving spouse, an Eligible
           Retirement Plan is an individual retirement account or individual
           retirement annuity.

       (c) A "Distributee" is an employee or former employee, the employee's or
           former employee's surviving spouse and the employee's or former
           employee's spouse or former spouse who is the alternate payee under a
           qualified domestic relations order, as defined in Section 414(p) of
           the Code.

       (d) A "Direct Rollover" is a payment by the Plan to the Eligible
           Retirement Plan specified by the Distributee.

                                                                   Page 44 of 68
 
               SECTION 9 - PARTICIPANT'S NONFORFEITABLE INTEREST


 9.01  GENERAL RULE.  A Participant's nonforfeitable (vested) interest prior to
       his Normal Retirement Date and as of December 31, 1988, shall be one
       hundred percent (100%), and for contributions on or after such date shall
       be an amount equal to the balance of his Accounts applicable to his
       number of Years of Participation as follows:

        Completed Years of Participation        Nonforfeitable Interest
        --------------------------------        -----------------------

               Less than 1 year                            None    
               1 Year                                      20%
               2 Years                                     40%
               3 Years                                     60%
               4 Years                                     80%
               5 Years                                     100%
                           
                           
       Upon the termination, or a partial termination, of this Plan, except as
       provided in Section 11, or upon complete discontinuance of contributions
       thereto by any Company, each affected Participant's interest in his
       separate accounts shall become one hundred percent (100%) nonforfeitable.

 9.02  SPECIAL RULES.  In applying the provisions of Section 9.01, Years of
       Participation shall refer to the total years of Service of an Employee
       with the following exceptions and modifications:

       (a) Subject to the provisions of (c) of this Section, an Employee's
           Service shall be deemed to commence on the January first following
           the date his actual employment commenced, except that if a prior
           Participant is reemployed and again becomes a Participant in the year
           of his reemployment pursuant to Section 2.02 his Service shall be
           deemed to have commenced on January first of the year of his
           reemployment.

       (b) If an Employee's employment is terminated during any calendar year,
           he shall receive no credit for any Service during such calendar year
           (unless the rule set forth in Section 1.25(c) applies).

       (c) In the case of an Employee who has five 1-Year Breaks in Service,
           Service after such Break in Service, shall not be taken into account
           for the purpose of determining his nonforfeitable interest in his
           Company Contribution Account before such Break in Service.  As
           provided at Section 2.02, any nonforfeitable vested interest of an
           Participant in the balance of his Company Contribution Account at the
           time of such Breaks in Service shall be separately accounted for
           thereafter as one hundred percent (100%) nonforfeitable.

                                                                   Exhibit 10(g)
                                                                   Page 45 of 68
 
       (d) In the case of a Participant who becomes an independent field sales
           representative for the Companies (and thereby ceases to be an
           Employee) any period of time that he is acting in such capacity and
           during which his accounts are not distributed to him shall be deemed
           to be Service.

       (e) Any period of time taken into account under the mergers set forth at
           Section 9.02(e) of the Aon Savings Plan shall be taken into account
           under this Plan.

       (f) If the Plan becomes a Top-Heavy Plan and subsequently ceases to be
           such, the vesting schedule in Section 16.05 shall continue to apply
           in determining the vested interest of any Participant who had at
           least three years of Service as of December 31st in the last Plan
           Year of top-heaviness. For other Participants, said schedule shall
           apply only to their Top-Heavy Account as of such December 31st.

       (g) A Participant's account shall be 100% vested and nonforfeitable when
           he earns five Years of Participation and attains age 55 and such date
           shall be regarded as his early retirement date.

 9.03  RESTORATION OF FORFEITURES.  Forfeitures from a terminated Participant's
       Accounts shall be charged to his Accounts upon termination of his
       employment; provided, however, that no forfeiture shall be incurred by a
       Participant reemployed on or before the following Anniversary Date if he
       does not receive a distribution under Section 8.04 by reason of such
       reemployment and if no administrative inconvenience as to such
       forfeitable amount would thereby be suffered by the Committee.  If any
       terminated Participant who has suffered a forfeiture becomes reemployed
       before he has incurred five consecutive 1-Year Breaks in Service, upon
       his earning a year of Service after his rehire his Accounts shall be
       reconstituted by crediting thereto an amount equal to the amount
       forfeited, which amount shall be deducted from forfeitures during the
       Plan Year in which his Accounts are reconstituted.  To the extent
       forfeitures for such year are not adequate for such purpose, such amount
       as may be necessary to reconstitute his Accounts shall be deducted pro
       rata from the assets of those funds earning a net Gain pursuant to the
       earnings and valuation adjustment under Section 8.07(a), and if there are
       no net Gains then such amount shall be deducted from Company
       contributions for the year.  As an alternative to either of the sources
       set forth in the preceding sentence, at the discretion of the Company
       such amount may be contributed by the Company as a special contribution
       and credited to such account.  In the event the employment of a rehired
       Participant whose account has been reconstituted is again terminated
       before he has acquired a 100% vested interest, any prior distribution
       made to him on account of his prior termination of employment shall be
       taken into consideration in computing his vested interest at the time of
       his later termination of employment.  Financed Shares allocated to a
       Participant's Stock Sub-Account shall be forfeited only after his
       interest in all other Plan assets has been exhausted.

                                                                   Page 46 of 68
 
 
                         SECTION 10 - SPENDTHRIFT TRUST


 10.01 GENERAL.  No Participant or Beneficiary shall have any right or power to
       transfer, assign, anticipate, mortgage, pledge or otherwise encumber his
       interest in the Trust established by this Agreement, or his rights to
       receive payments or benefits from the Trust and neither such interest nor
       rights nor any assets of the Trust shall be subject to seizure or
       sequestration for the payment of any debts, judgments, alimony or
       separate maintenance owed by any Participant or Beneficiary nor to
       transferability by operation of law in the event of bankruptcy,
       insolvency or otherwise;  provided, that this limitation shall not apply
       to a Qualified Domestic Relations Order ("QDRO") under IRC Section
       401(a)(13) as amended from time to time.

 10.02 QUALIFIED DOMESTIC RELATIONS ORDER.  For purposes of this Section, a QDRO
       shall mean a domestic relations order which relates to alimony, child
       support or marital property rights and which has been determined by the
       Company to meet the requirements of IRC Section 414(p) as amended from
       time to time.  The following rules shall apply to the rights and
       obligations of the spouse of a Participant under a QDRO and under a
       domestic relations order not yet determined to be a QDRO.

       (a) These rules shall apply prior to determination by the Plan
           administrator that the domestic relations order is a QDRO, and shall
           apply thereafter as applicable.

           (i)   As soon as administratively feasible after receipt of a
                 domestic relations order, those funds which will go to the
                 spouse if she (or he) should be determined to be entitled
                 thereto will be put into a separate account.

           (ii)  The spouse will share in any intervening gains (or losses)
                 enjoyed (or suffered) by the Participant in his accounts
                 between the time of the domestic relations order and when the
                 Company is notified of the existence thereof and has been
                 afforded a reasonable time to transfer the funds which would go
                 to the spouse into a separate account.

           (iii) An account or account balances may be segregated for the spouse
                 even though the Participant is not yet eligible to have funds
                 distributed to him (or her). The spouse's funds may be
                 accounted for separately without the necessity for an escrow.

           (iv)  The spouse may elect a Beneficiary for her (or his) account
                 balances under the QDRO. If a property settlement agreement is
                 involved or some other court decree which is not a final
                 divorce so that the individuals remain married, the Participant
                 shall be treated as her

                                                                   Exhibit 10(g)
                                                                   Page 47 of 68
 
 
                 death Beneficiary, just as the spouse will be for the
                 Participant, unless the QDRO provides otherwise.  If the QDRO
                 provides that the spouse is to be no longer regarded as the
                 Participant's spouse, then the preceding sentence shall not
                 apply.

           (v)   Upon written notification from either the Participant or spouse
                 that a QDRO is forthcoming no distribution of benefits will be
                 made to the Participant until the later of:

                 (A)  Ninety days after the date the Company has sent the Aon
                      QDRO Procedures to the parties and no domestic relations
                      order has been received, or

                 (B)  the period that the Company is reviewing a domestic
                      relations order to determine if it is a QDRO.

       (b) These rules shall apply once the domestic relations order has been
           determined to be QDRO.

           (i)   The spouse may take all of her (or his) account balances at any
                 time, without regard to whether the Participant has attained
                 his (or her) earliest retirement age under the Plan. Any
                 benefits distributed under this rule may be taken out only in a
                 single sum and may not be taken out periodically or pro rata.

           (ii)  The spouse may not take a partial withdrawal of her (or his)
                 account balances.

           (iii) If the amount to be distributed to the spouse is less than
                 $3,500, such amount will be paid out only in a lump sum and may
                 be distributed without the consent of the spouse or of the
                 Participant.

           (iv)  A distribution otherwise permissible may be made to the spouse
                 without regard to whether the limitations on a distribution
                 under IRC Section 401(a) are met.

       (c) It is the intent of this Subsection that the rules set forth herein
           shall be subject to, and shall be interpreted in light of, the
           requirements for a QDRO under the IRC and under the regulations and
           rulings of the Secretary of the Treasury and his delegate.  This
           Subsection shall also apply to a child or other dependent of the
           Participant as appropriate.

               SECTION 11 - COMPANY TO HAVE NO INTEREST IN TRUST


The Company shall in no event, either directly or indirectly, receive any fund
or contributions made by it to the Trust, nor directly or indirectly participate
in the distribution, or receive the benefits of the assets or funds comprising
the Trust prior to the satisfaction of all liabilities with respect to
Employees, beneficiaries, and spouses under this Plan; provided, however, that
(subject to the limitations of Revenue Ruling 91-4):

       (a) If a contribution is made by a mistake of fact, the mistaken portion
           of the contribution shall returned within one year after payment of
           the mistaken contribution upon Company's written request; and

       (b) Each contribution by the Company is conditioned upon the
           deductibility of the contribution under the applicable section of the
           IRC.  Accordingly, to the extent of disallowance of the decuction for
           the part or all of the contribution, the contribution shall be
           returned within one year after disallownance upon the Employer's
           written request.

Upon transfer to the Trustees, all responsibilities of the Company for each
contribution shall cease, and Company shall have no responsibilities for the
acts of the Trustees.

             SECTION 12 - AMENDMENT AND SUSPENSION OF CONTRIBUTIONS


 12.01 AMENDMENT OF THE AGREEMENT.  Aon reserves the right, by action of the
       Board, to amend this Agreement at any time, and from time to time,
       including the right to change the provisions for each Company's
       contributions; provided that the contribution of Combined Life Insurance
       Company of New York for its Life Insurance Agents shall not be changed or
       modified without its consent.  No amendment shall vest in the Companies
       any right, title or interest in and to the Trust Fund, or any part
       thereof, or cause them to be used or diverted to, purposes other than for
       the exclusive benefit of Participants and beneficiaries.  The amendment
       of this Agreement shall not require the approval or ratification of the
       stockholders of Combined, or any Subsidiary, nor of the Trustee,
       Committee, Participants or Beneficiaries, or any of them; however, no
       amendment shall change the rights, duties, or responsibilities of the
       Trustee without its written consent.  Except as may be necessary to
       qualify this Trust, or to continue the qualification of the Trust under
       Section 4975(e) of the Internal Revenue Code, or any successor to such
       section, no amendment shall adversely affect vested rights of any
       Participant hereunder.

 12.02 SUSPENSION.  Except for contributions required under Section 3.01(a)(2),
       Aon reserves the right, by action of the Board, to suspend Aon's or any
       Subsidiary's contributions for any Plan Year, but not exceeding two
       successive Plan Years, without  terminating the Plan and Trust or
       discontinuing contributions permanently, by providing written notice of
       such action of the Board to the Committee and Trustee not later than
       sixty (60) days prior to the end of such Plan Year, in which event the
       Company or Companies affected shall not be obliged to make any
       contribution to the Company Fund for the period of such suspension.  The
       Committee upon receiving notice of such suspension shall immediately
       notify the affected Participants.

                   SECTION 13 - ADOPTION OF PLAN BY AFFILIATE


 13.01 ADOPTION OF PLAN.  Any Affiliate, by proper resolutions adopted by its
       Board, or by an adoption agreement executed by a principal executive
       officer, may become a party to this Agreement by adopting this Trust as a
       stock bonus plan for its Employees.  A certified copy of such resolutions
       shall be delivered to the Committee and Trustee.

 13.02 INTENTION OF PARTIES.  Accept as provided herein, it is the intention of
       the parties hereto that the Employees of Aon and the Employees of any
       Subsidiary that adopts this Trust shall receive the same benefits as they
       would receive if Aon and such Subsidiaries were one corporate entity and
       this Plan were the plan of such entity, and the provisions of this
       Agreement shall be interpreted in accordance with this intent.

 13.03 TERMINATION OF STATUS OF SUBSIDIARY.  In the event any Subsidiary
       adopting this Plan at any time does not meet the requirements herein set
       forth for a Subsidiary, such company shall nevertheless be considered as
       continuing its status as a Subsidiary unless Aon files with the Trustee
       and Committee a resolution adopted by its Board electing to discontinue
       such Company's participation hereunder.  Such resolution shall be
       considered as an election to terminate such company's participation in
       this Trust under the provisions of Section 8.05(a).

          based.

14.05 INVESTMENT IN DEPOSITS WITH CORPORATE FIDUCIARY. In the event a corporate
      fiduciary is appointed pursuant to Section 6.01, such fiduciary may invest
      all or part of the Plan's assets in deposits, which bear a reasonable rate
      of interest, in an account maintained in its own banking department, to
      the extent such investment is permitted by Section 408(b) of ERISA.

14.06 MAXIMUM ANNUAL ADDITION.

      (a) In no event shall the annual addition (as hereinafter defined) to a
          Participant's separate accounts with respect to any Plan Year exceed
          the lesser of

          (i)   $30,000 (or, if greater, one-fourth of the defined benefit plan
                dollar limitation under Section 415(b) of the IRC); provided,
                however, that such dollar amount may be increased by the lesser
                of (A) 100% of the dollar amount otherwise applicable for that
                Plan Year, or (B) the amount of Employer Securities allocated as
                Company contributions to the Participant for that Plan Year, but
                only if not more than one-third (1/3) of the Company
                contributions for the Plan Year are allocated to Highly
                Compensated Employees, or

          (ii)  Twenty-five percent (25%) of the Participant's total
                compensation.

      (b) The term "annual addition" means the sum for any Plan Year of

          (i)   his share of Company contributions, plus

          (ii)  the amount of his Employee contributions made on or after
                January 1, 1987, plus

          (iii) his share of forfeitures, plus

          (iv)  for purposes of Section 14.06(a)(i) only, amounts allocated to 
                a separate account for the Participant to provide medical
                benefits after retirement, whether under a pension or annuity
                plan or a welfare benefit fund, pursuant to Sections 401(h),
                415(c), 415(l) and 419(d)(2) of the IRC.

          In determining annual additions, forfeitures of Company Stock shall be
          based upon the Value of Company Stock as of the Anniversary Date. Any
          Company contributions which are applied (not later than the due date,

                                      175

                                                                   Page 53 of 68

          including extensions, for filing the Company's Federal income tax
          return for that Plan Year) to pay interest on an Acquisition Loan, and
          any Financed Shares which are allocated as forfeitures, shall not be
          included as annual additions provided, however, that the provisions of
          this sentence shall be applicable only in Plan Years for which not
          more than one-third (1/3) of the Company contributions applied to pay
          principal and interest on an Acquisition Loan are allocated to the
          Highly Compensated Employees.  The Trustees may reallocate such
          Company contributions in order to satisfy this special limitation.

      (c) In the event a Participant herein also participates in any other
          stock bonus plan maintained by the Company or a member of a controlled
          group (as defined in Section 14.02) the maximum annual addition
          computed pursuant to subsection (a) hereof may be reduced (except as
          IRC Section 415(c)(6) may apply) by the amount of employer
          contributions and forfeitures allocated to the Participant in such
          plan; provided, however, that if the Participant also participates in
          another profit sharing plan, then the maximum annual addition
          hereunder may be reduced subsequent to the maximum annual addition
          under such plan; employee contributions made by the Participant to
          such other plans shall be included in computing his annual addition
          pursuant to subsection (b)(ii) hereof; and compensation received from
          a member of a controlled group shall be included in total
          compensation.

      (d) In the event a Participant herein is a Participant at any time in a
          defined benefit plan maintained by the Company or a member of a
          controlled group, the sum of the defined benefit plan fraction and the
          defined contribution plan fraction for any Plan Year shall not exceed
          1.0 but such limitation may be applied to first reduce benefits under
          the defined benefit plan before being applied to reduce benefits under
          this plan.  For this purpose the defined benefit plan fraction for any
          Plan Year is:

                Project annual benefit of the Participant under
                the plan (determined as of the close of the year)
                -----
                Lesser of: (a) 1.25 multiplied by the dollar
                limitation in effect for such year ($90,000 for 
                Plan Year beginning in 1983) or (b) 1.4 multiplied
                by the percentage limitation with respect to 
                such individual under the plan for such year 
                (100% of his average total compensation for his 
                high 3 Years).

          The defined contribution plan fraction for any Plan Year is:

                                                                   Exhibit 10(g)
                                                                   Page 54 of 68

                Sum of the annual additions to the Participant's
                account as of the close of the year
                ------------------------------------------------
                Sum of the lesser of the following amounts 
                determined for such year and for each prior year 
                of service with the employer: (a) 1.25 
                multiplied by the dollar limitation in effect
                for such year ($30,000 for Plan Year beginning in 
                1983) or (b) 1.4 multiplied by the percentage 
                limitation with respect to such individual 
                under the Plan for each such year (25% of his 
                total compensation).

      (e) At the election of the plan administrator, in determining the defined
          contribution plan fraction under Subsection (d), above, with respect
          to any Plan Year ending after December 31, 1982, the denominator of
          the fraction with respect to each Participant for all years ending
          before January 1, 1983, shall be an amount equal to the product of
          such denominator under the law in effect for the year ending in 1982
          multiplied by the transition fraction.  The transition fraction means
          a fraction whose numerator is 35% of the compensation of the
          Participant for the year ending in 1981 (limited to $51,875) and whose
          denominator is 25% of such compensation (but not more than $41,500).

      (f) Provided the Plan satisfied the requirements of IRC Section 415 for
          the last year beginning before January 1, 1983, and pursuant to
          regulations prescribed by the Secretary of the Treasury or his
          delegate, the numerator of the defined contribution plan fraction at
          Subsection (d) may be reduced so that the sum of the defined
          contribution plan fraction and the defined benefit plan fraction does
          not exceed 1.0 for such year.

      (g) In the case of an individual who is a participant before January 1,
          1983, in a defined benefit plan which is in existence on July 1, 1982,
          and with respect to which the requirements of Section 415 of the IRC
          have been met for all years, if such individual's current accrued
          benefit under such plan exceeds the limitation of subsection (b) of
          Section 415, then (in the case of such plan) for purposes of such IRC
          Section 415(b), and also for purposed of IRC Section 415(e) as
          provided under Subsection (d) through (f) hereof, the limitation of
          such IRC Section 415(b) with respect to such individual shall be equal
          to such current accrued benefit.  The term "current accrued benefit"
          means the individual's accrued benefit (at the close of the last year
          beginning before January 1, 1983) when expressed as an annual benefit
          (within the meaning of Section 415(b)(2) of the IRC as in effect
          before the amendments made by the Tax Equity and Fiscal Responsibility
          Act of 1982).  For purposes of determining the amount of any
          individual's current accrued benefit, (i) no change in the terms and
          conditions of the plan after July 1, 1982, and (ii) no cost-of-living
          adjustment occurring after July 1, 1982, shall be taken into account.

                                                                   Page 55 of 68
 
      (h) In the event the amount of the annual addition for a Participant
          exceeds the limitation of this Section 14.06, the Trustees shall
          forthwith reduce the amount of the annual addition to the limitation
          of Section 14.06 by first refunding any contributions of the
          Participant for such Plan Year to the extent includable in the
          computation of the annual addition; second, if necessary, by reducing
          his share of the Company's contribution for such Plan Year, the amount
          of such reduction to be applied as a reduction of the Company's
          contribution for such Plan Year. Any remaining excess contributions
          plus forfeitures, shall be reallocated among the other Participants.
          If after such adjustments there still remains an excess, such amounts
          from such Participants so affected shall be held unallocated in a
          suspense account and all amounts in the suspense account shall be
          allocated and reallocated to Participant's accounts (subject to the
          limitations of Section 415 of the IRC) before any contributions by the
          Company or by the Participants may be made for the limitation year
          during which such suspense accounts are in existence.

      (i) In determining under which plan the contributions or other annual
          additions, or benefits, of a Participant should be reduced under this
          Section, the intent is that the order of reduction set forth herein be
          for purposes of guidance only and not obligatory, and that such order
          of reduction as to one Participant may be different from another
          Participant, so as to afford maximum flexibility to the Plan in
          avoiding a violation of the provisions of Section 415 of the IRC.

      (j) If the Plan satisfied the applicable requirements of Section 415 of
          the IRC as in effect for all years beginning before January 1, 1987,
          an amount shall be subtracted from the numerator of the defined
          contribution plan fraction (not exceeding such numerator) as
          prescribed by the Secretary of the Treasury so that the sum of the
          defined benefit plan fraction and defined contribution plan fraction
          computed under Section 415(e)(1) of the IRC does not exceed 1.0 for
          such year.

      (k) Compensation shall include the following items:

          (i)   The Participant's wages, salaries, fees for professional service
                and other amounts received for personal services actually
                rendered in the course of employment with an employer
                maintaining the plan (including but not limited to, commissions
                paid salesmen, compensation for services on the basis of a
                percentage of profits, commissions on insurance premiums, tips
                and bonuses).

          (ii)  For purposes of the prior sentence, earned income from sources
                outside the United States.

          (iii)  Amounts described in IRC Sections 104(a)(3), 105(a) and 105(h),
                 but only to the extent that these amounts are includable in 
                 the gross income of the Employee.

          (iv)   Amounts described in IRC Section 105(d), whether or not these
                 amounts are excludable from the gross income of the Employee
                 under that Section.

          (v)    Amounts paid or reimbursed by the Employer for moving expenses
                 incurred by an Employee, but only to the extent that these
                 amounts are not deductible by the Employee under IRC Section
                 217.

          (vi)   The value of a non-qualified stock option granted to an 
                 Employee by the employer, but only to the extent that the value
                 of the option is includable in the gross income of the Employee
                 for the taxable year in which granted.

          (vii)  The amount includable in the gross income of an Employee upon
                 making the election described in IRC Section 83(b).

          Compensation shall not include the following items:

          (viii) Contributions made by the Employer to a plan of deferred
                 compensation to the extent that, before the application of the
                 IRC Section 415 limitations to that plan, the contributions are
                 not includable in the gross income of the employee for the
                 taxable year in which contributed. In addition, Employer
                 contributions made on behalf of an Employee to a simplified
                 employee pension described in IRC Section 408(k) are not
                 considered as compensation for the taxable year in which
                 contributed to the extent such contributions are deductible by
                 the Employee under IRC Section 219(b)(7). Additionally, any
                 distributions from a plan of deferred compensation are not
                 considered as compensation for IRC Section 415 purposes,
                 regardless of whether such amounts are includable in the gross
                 income of the Employee when distributed. However, any amounts
                 received by an Employee pursuant to an unfunded non-qualified
                 plan may be considered as compensation for IRC Section 415
                 purposes in the year such amounts are includable in the gross
                 income of the Employee.

          (ix)   Amounts realized from the exercise of a non-qualified stock
                 option, or when restricted stock (or property) held by an
                 Employee either becomes freely transferable or is no longer
                 subject to a substantial risk of forfeiture (see IRC Section 83
                 and the regulations thereunder.)

          (x)    Amounts realized from the sale, exchange or other disposition 
                 of stock acquired under a qualified stock option.

                 premiums for group term life insurance (but only to the extent
                 that the premiums are not includable in the gross income of the
                 Employee), or contributions made by an Employer (whether or not
                 under a salary reduction agreement) towards the purchase of an
                 annuity contract described in Section 403(b) (whether or not
                 the contributions are excludable from the gross income of the
                 Employee).

      (l) Except as provided in regulations, the provisions of IRC Section 415
          are hereby incorporated by reference to the extent not set forth in
          this Section.

       furnished by the Companies to the Committee or Trustee, such as
       Compensation of Participants, the proper amount of the Companies'
       contribution, the status of individuals as Employees of the Companies, or
       otherwise, and any other information which may be furnished by the
       companies to the Committee or Trustee, shall be accepted by the Committee
       and Trustee as being true and correct, and the Committee or Trustee shall
       incur no liability in relying on such information.  In no event shall the

       investigation, or disclosure of the Companies' books or records.

 15.02 INABILITY TO PERFORM.  Neither the Companies, the Committee nor the
       Trustee shall be responsible for any inability to perform, or delay in
       performing, any act occasioned by any restriction or provision of any
       annuity contract or Acquisition Loan, or imposed by any insurer, or by
       any other person, or by law, and in the event any such inability or delay
       shall be so occasioned, then than act which can be performed shall be
       performed by the Companies, the Committee, or the Trustee which, in the
       sole discretion of the Committee, most completely carries out the
       intention and purpose of this Trust.  All parties to this Trust or in any
       way interested therein shall be bound by any act so performed under such
       conditions.

 15.03 EXECUTION OF DOCUMENTS.  All parties to this Trust or claiming any
       interest hereunder expressly agree to perform any and all acts, and to

       Trust.

 15.04 NOTICE OF REQUIRED ACTION.  In any case in which the Companies, the
       Trustee, or the Committee shall be directed to take any action upon the
       occurrence of any event, they, or any one or more of them, shall be under
       no obligation or liability to take such action unless and until notice,
       proper and satisfactory to them, shall first have been received of the
       occurrence of such event.  For the purposes of this Section 15.04, a
       certificate in writing signed by any officer of Aon and delivered to the
       Trustee or the Committee as to the occurrence or happening of any event,
       shall constitute conclusive evidence of such occurrence or happening, and

       discharged from all liability whatsoever in accepting and relying on such
       certificate.

 15.05 RELIANCE UPON COMMUNICATION.  Neither the Companies, the Committee, nor
       the Trustee shall incur any liability in acting upon any notice, request,
       signed letter, telegram, or other paper or documents reasonably believed

       proper person.

       constitute a complete acquittance and discharge of full liability of the
       Trustee with respect to such participation.

 15.07 DISPOSITION OF SHARE OF MISSING PERSONS.  In the event the Committee is
       unable to make payment of any benefit payable under this Plan because of
       inability to find the person to whom payment is due and such inability
       continues for a period of two years, the benefit shall be forfeited;
       provided, however, if a claim is subsequently made for such benefit by
       the person entitled thereto, such benefit shall be reinstated.

 15.08 GENDER AND CASE.  Where used in this Agreement, words in the masculine
       shall be read and construed as in the feminine, and words in the singular

       where such constructions would so apply.

 15.09 SECTION TITLE NOT PART OF AGREEMENT.  The section and subsection
       designations and titles are included solely for convenience and shall, in
       no event, be construed to affect or modify any of the provisions of this
       Agreement or be construed as a part thereof.

 15.10 CONSTRUCTION.  It is intended that this Plan and the Trust Agreement
       which is a part thereof shall comply with the provisions of ERISA,
       constitute a qualified plan and trust under the provisions of sections
       401(a) and 4975(e) of the IRC and be operated in a manner so as not to
       discriminate in favor of Highly Compensated Employees.  Accordingly, the
       provisions of this Plan and Trust Agreement shall be construed and
       applied in a manner consistent with such intent.  However, to the extent
       not superseded by ERISA, this plan and the Trust Agreement which is a
       part thereof, shall be construed and enforced in accordance with the laws
       of the State of Illinois.

 15.11 AGREEMENT BINDING ON ALL PARTIES.  This Agreement shall be binding upon
       the heirs, executors, administrators, successors, and assigns of any and
       all parties hereto, present and future.

          SECTION 16--PROVISIONS APPLICABLE IF PLAN BECOMES TOP-HEAVY


 16.01 APPLICABILITY.  The provisions of this Section 16 shall be applicable
       during any Plan Year only if the Plan was a Top-Heavy Plan or was part of
       a Top-Heavy Group on the Determination Date, and in such case shall
       override and supersede all other provisions in this Plan to the contrary;
       provided, that these provisions shall not apply to a Plan which is not
       itself a Top-Heavy Plan and which was included in an Aggregation Group
       under the second sentence of Section 16.02(f); provided further, that, to
       the extent permitted by law, Section 16.06 shall not apply to any
       Employee who has received the minimum benefit for the Plan Year as
       required under the Top-Heavy rules from any defined benefit plan of the
       Company.

 16.02 ADDITIONAL DEFINITIONS:

       (a) KEY EMPLOYEE.  The term "Key Employee" shall refer to any Employee
           who, at any time during the Plan Year or any of the four preceding
           Plan years, is

           (i)   an Officer of the Company, excluding any Employee whose
                 Compensation is less than 150 percent (150%) of the maximum
                 dollar limitation in Section 14.06(a)(i),

           (ii)  one of the ten Employees owning [or considered as owning within
                 the meaning of Section 318 of the IRC but substituting 5% for
                 50% in Section 318(a)(2)(C) the largest interests in the
                 Company; excluding any Employee whose Compensation is less than
                 the maximum dollar limitation in Section 14.06(a)(i),

           (iii) a Five Percent Owner of the Company, or

           (iv)  a One Percent Owner of the Company having an annual
                 compensation from the Company of more than $150,000.

       The term shall also include beneficiaries of a Key Employee.  For
       purposes of clause (i), no more than 50 Employees (or, if less, the
       greater of 3 or 10% of the Employees) shall be treated as officers, and
       the officers taken into account shall be the officers with the highest
       compensation.  For purposes of clause (ii), if two Employees have the
       same interest in the Company, the Employee having greater annual
       Compensation from the Company shall be treated as having a larger
       interest.  For this purposes of clauses (ii), (iii) and (iv), the
       aggregation rules of subsections (b), (c) and (m) of Section 414 of the
       IRC (pertaining to employees of a controlled group of corporations, of
       partnerships and proprietorships under common control, and of an
       affiliated service group) shall not apply.

                                                                   Page 61 of 68
 
       (b) FIVE PERCENT OWNER.  The term "Five Percent Owner" shall mean any
           person who owns [or is considered as owning within the meaning of
           Section 318 of the IRC but substituting 5% for 50% in Section
           318(a)(2)(C)] more than five percent of the outstanding stock of the
           Company or stock possessing more than five percent of the total
           combined voting power of all stock of the Company.

       (c) ONE PERCENT OWNER.  The term "One Percent Owner" means any person who
           owns [or is considered as owning within the meaning of Section 318 of
           the IRC but substituting 5% for 50% in Section 318(a)(2)(C)] more
           than one percent of the outstanding stock of the Company or stock
           possessing more than one percent of the total combined voting power
           of all stock of the Company.

       (d) NON-KEY EMPLOYEE.  The term "Non-Key Employee" shall refer to any
           Participant who is not a Key Employee.

       (e) TOP-HEAVY PLAN.  A Plan is a "Top-Heavy" Plan if, as of the
           Determination Date, the aggregate of the accounts of Key Employees
           under the Plan exceed 60% of the aggregate of the accounts of all
           Employees under the Plan; or if it is required to be included in an
           Aggregation Group and such Aggregation Group is a Top-Heavy Group;
           provided, that the Plan shall not be a Top-Heavy Plan if the Plan is
           part of an Aggregation Group which is not a Top-Heavy Group.

       (f) AGGREGATION GROUP.  The term "Aggregation Group" means (i) each plan
           of the Company in which a Key Employee is a Participant and (ii) each
           other plan of the Company which enables any plan described in (i) to
           meet the discrimination requirements of Section 401(a)(4) of the IRC
           or the minimum participation standards of Section 410 of the IRC.  In
           addition, at the option of the Company, it may include any other plan
           of the Company if the Group would continue to meet the requirements
           of Sections 401(a)(4) and 410 of the IRC with such other plan being
           taken into account.

       (g) TOP-HEAVY GROUP.  An Aggregation Group is a "Top-Heavy Group" if, as

           Group, exceeds (iii) 60% of a similar sum determined for all
           Employees.

       (h) EMPLOYEE.  The term "Employee" shall include the Beneficiaries of
           such Employee.

                                                                   Page 62 of 68
 
       (i) DETERMINATION DATE.  The term "Determination Date" shall mean, with
           respect to any Plan Year, the last day of the preceding Plan Year.
           All required valuations shall be made as of the Determination Date.

       (j) COMPENSATION. The term "Compensation" shall mean total compensation
           but shall not include annual compensation in excess of $200,000 (as
           adjusted for cost-of-living increases by the Secretary of his
           delegate at the same time and in the same manner as the dollar amount
           under Section 14.06). Effective January 1, 1989, this Section
           16.02(j) shall no longer apply.

 16.03 SPECIAL RULES.  In determining whether the Plan is a Top-Heavy Plan or
       part of a Top-Heavy Group, the following rules shall apply.

       (a) Except to the extent provided in regulations issued by the Secretary
           of the Treasury, any rollover contribution (or similar transfer)
           initiated by an Employee from a plan not maintained by the Company
           and made after December 31, 1983, to a plan shall not be taken into
           account with respect to the transferee plan.

       (b) If any individual is a Non-Key Employee with respect to the Plan for
           any Plan Year, but such individual was a Key Employee with respect to
           the Plan for any prior Plan Year, any accrued benefit for such
           Employee (and the account of such Employee) shall not be taken into
           account for purposes of Sections 16.02(e) and (g).

       (c) To the extent provided in regulations issued by the Secretary of the
           Treasury, the Top-Heavy rules of this Section shall be applied on the
           basis of any year specified in such regulations in lieu of Plan
           Years.

       (d) In determining present values and account balances under Section
           16.02(e) and (g), all distributions made with respect to any Employee
           during the 5-year period ending on the Determination Date shall be
           added back and included therein.  The preceding sentence shall also
           apply to distributions under a terminated plan which if it had not
           been terminated would have been required to be included in an
           Aggregation Group.

       (e) In determining the account of any Participant under 16.02(e) or (g),
           amounts attributable to deductible employee contributions shall not
           be considered.

       (f) If any individual has not performed services for any employer
           maintaining this Plan at any time during the 5 year period ending on
           the Determination Date, any accrued benefit for such individual and
           his accounts shall not be taken into account.

 16.04 PARTICIPANT'S TOP-HEAVY ACCOUNT.  An additional separate account shall be
       established for each Participant to be known as the Participant's Top-
       Heavy

                                      185

                                                                   Page 63 of 68

       Account to which shall be posted his share of Company's contributions,
       forfeitures and net earnings and valuation adjustments for each Plan Year
       to which Section 16 is applicable.  His share of the Company's
       contributions, forfeitures and net earnings and valuation adjustments
       that have been posted to his Company Contribution Account pursuant to
       Section 4.02 for all prior Plan Years shall be transferred to his Top-
       Heavy Account.

 16.05 VESTING WITH RESPECT TO PARTICIPANTS' TOP-HEAVY ACCOUNTS.  In lieu of the
       vesting schedule set forth in Section 9.01(a), a Participant, provided he
       earns at least one Hour of Service after the Plan has become Top-Heavy,
       shall vest in his Top-Heavy Account according to the following schedule:

       <TABLE>
       <S>                           <C>
       Completed Years of Service    Non-Forfeitable %
       --------------------------    -----------------
 
          Less than 3                      -0-
              3                           100%
       </TABLE>
       provided, that a Participant's nonforfeitable (vested) interest in his
       Top-Heavy Account, as regards funds transferred from his Company
       Contribution Account for prior years as set forth in Section 16.04, shall
       not be reduced from his nonforfeitable interest therein under Section
       9.01.

 16.06 MINIMUM CONTRIBUTION FOR NON-KEY EMPLOYEES. The Company's contribution
       and forfeitures allocated to the Top-Heavy Account for each Plan Year for
       each Non-Key Employee shall not be less than 3% of his compensation as
       defined at IRC Section 416(c)(2)(A), except that said percentage shall
       not be more than the highest percentage at which Company contributions
       plus forfeitures are made for any Key Employee. The percentage for each
       Key Employee shall be determined by dividing the amount of his shares of
       the Company's contribution plus forfeitures by the amount of so much of
       his Compensation as does not exceed $200,000. For this purpose, all
       defined contribution plans required to be included in an Aggregation
       Group shall be treated as one plan. The foregoing exception to the 3%
       provision shall not apply if the Plan is required to be included in an
       Aggregation Group wherein the Plan enables a defined benefit plan
       required to be included in such Group to meet the requirements of
       Sections 401(a)(4) and 410 of the IRC pertaining to discrimination and
       minimum participation. The minimum contribution rules of this Section
       16.06 may be satisfied by taking into account Company contributions
       attributable to a salary reduction or similar arrangement. The allocation
       provisions contained in Section 4 of this plan shall be modified as may
       be necessary to comply with the provisions of this Section 16.06 and the
       Company may, but shall not be required to, increase Company contributions
       so no Participant will incur a reduction of benefits by reason of the
       operation of this Section 16.06.

 16.07 MAXIMUM ANNUAL ADDITION. The limitations of Section 14.06 shall be
       applied by substituting 1.0 for 1.25 where it appears in Section 14.06(d)
       in the denominators

       of the defined benefit plan fraction and the defined contribution plan
       fraction. The preceding sentence shall not apply if

                                                                   Page 10 of 91
 
                            SECTION 2 - DEFINITIONS


  Unless the context shall otherwise clearly indicate, the following terms shall
be construed as hereafter defined:

 2.01  "ACCRUED RETIREMENT INCOME" shall mean the monthly amount determined at
       any time in accordance with Section 4.01 of the Plan, but based on Years
       of Service and Final Average Earnings as of the Participant's
       determination date on or after his Normal Retirement Date or Termination
       Date, whichever is applicable; provided, however, that the Accrued
       Retirement Income of a Participant as of December 31, 1988, who would
       have earned more than 30 Years of Service at his Normal Retirement Date
       if he had continued in employment and earned 40 Hours of Service a week
       until his Normal Retirement Date shall not be less than the Normal
       Retirement Benefit he would have been eligible to receive on his Normal
       Retirement Date (based on the above assumptions but determined on the
       basis of Final Average Earnings and his Primary Social Security Benefit
       (as defined prior to the 1989 Restatement of the Plan) on December 31,
       1988) multiplied by a fraction the numerator of which shall be his Years
       of Service on December 31, 1988, and the denominator of which shall be
       the Years of Service he would have had if he had continued in employment
       until his Normal Retirement Date.   In applying the above proviso, Years
       of Service that are normally not counted for benefit accrual purposes (as
       provided in Sections 3.05, 3.06 and 3.07) shall be counted except for the
       purpose of determining the numerator of the fraction referred to in the
       preceding sentence, and the Participant shall be deemed to have earned
       Years of Service after December 31, 1988, even if he was employed in a
       capacity and location where he was not earning Years of Service, for
       benefit accrual purposes immediately before December 31, 1988.

 2.02  "ANNUAL EARNINGS"
       (a) Annual Earnings with respect to calendar years prior to 1993 shall
           mean the regular salary of an Employee excluding any bonuses or extra
           remuneration, but determined before excluding any reduction described
           in Sections 3.03 and 3.04 of the Aon Savings Plan, or before
           excluding any reduction for cafeteria plans under Section 125 of the
           IRC, paid to him by the Employer during any calendar year for his
           services to the Employer in the capacity of a staff

                                                                   Page 11 of 91
 
           Employee. Such Annual Earnings shall also include, for
           representatives of the Life Insurance Company of Virginia only,
           financing/subsidy payments, first year commissions, renewal
           commissions, first year overrides, renewal overrides, personal
           service fees, managerial service fees, and validation bonuses.

       (b) Annual Earnings with respect to calendar years after 1992 shall mean
           the following types of earnings paid to an Employee for his service
           on behalf of the Employer determined before excluding any reduction
           described in Sections 3.03 and 3.04 of the Aon Savings Plan, or
           before excluding any reduction for cafeteria plans under Section 125
           of the IRC:

          (i)  salary and fixed base compensation including compensation for
               overtime;

          (ii) bonuses paid pursuant to periodic individual performance
               appraisals and formal contractual bonus programs, but excluding
               other bonus and miscellaneous income;

          (iii)net commission, renewal and override compensation (but
               excluding deferred commission payments).

          Annual Earnings shall not include remuneration reported to the
          Internal Revenue Service on Form 1099 or amounts deferred under a
          nonqualified deferred compensation Plan.

          In addition to other applicable limitations set forth in the Plan, and
          notwithstanding any other provision of the Plan to the contrary, for
          Plan Years beginning on or after January 1, 1994, the Annual Earnings
          of each Employee taken into account under the Plan shall not exceed
          the OBRA '93 annual compensation limit.  The OBRA '93 annual
          compensation limit is $150,000, as adjusted by the Commissioner of the
          Internal Revenue Service for increases in the cost of living in
          accordance with section 401(a)(17)(B) of the IRC.  The cost-of-living
          adjustment in effect for a calendar year applies to any period, not
          exceeding 12 months, over which compensation is determined
          (determination period) beginning in such calendar year. If a
          determination period consists of fewer than 12 months, the OBRA '93
          annual

                                      202

                                                                   Exhibit 10(H)
                                                                   Page 12 of 91

          compensation limit will be multiplied by a fraction, the numerator of
          which is the number of months in the determination period, and the
          denominator of which is 12.

          For Plan Years beginning on or after January 1, 1994, any reference in
          this Plan to the limitation under section 401(a)(17) of the Code shall
          mean the OBRA '93 annual compensation limit set forth in this
          provision.

          If compensation for any prior determination period is taken into
          account in determining an employee's benefit accruing in the current
          plan year, the compensation for that prior determination period is
          subject to the OBRA '93 annual compensation limit in effect for that
          prior determination period.  For this purpose, for determination
          periods beginning before the first day of the first Plan Year
          beginning on or after January 1, 1994, the OBRA '93 annual
          compensation limit is $150,000.  In determining compensation, the
          family member rule for Highly Compensated Employees shall apply, but
          be limited to the Employee's spouse and lineal descendants under 19
          years of age.

 2.03  "ANNUITY STARTING DATE" shall mean the first day of the first period for
       which the Participant or Beneficiary receives an annuity.

 2.04  "AUTHORIZED LEAVE OF ABSENCE" means any absence authorized by the
       Employer because of illness, military service, or for any other reason.
       Authorized Leaves of Absence shall be granted on a uniform and non-
       discriminatory basis.

 2.05  "BOARD" shall mean the present and any succeeding Board of Directors of
       the Company or any committee of the Board of Directors delegated
       authority to act for the whole Board in respect of matters relating to
       the Plan.

 2.06  "COMMITTEE" shall mean the administrative committee designated by the
       Board in accordance with Section 12.  The Committee is designated as the
       administrator, plan administrator, and named fiduciary with respect to
       the administration of the Plan (but not with respect to the control,
       management and investment of the assets of the Trust) for the purposes of
       ERISA.

 2.07  "COMPANY" shall mean Aon Corporation and any successor.

                                                                   Exhibit 10(H)
                                                                   page 13 of 91
 
 2.08  "EFFECTIVE DATE" shall mean January 1, 1973, but shall refer to January
       1, 1994 when applied to the 1994 restatement of this Plan.

 2.09  "EMPLOYEE" shall mean any person employed by the Employers who is not a
       Field Sales Agent.

 2.10  "EMPLOYER" shall mean the Company and such of its subsidiaries as have
       adopted or shall adopt this Plan for the benefit of its Employees.  The
       term "Employers" as used herein shall refer collectively to all of the
       Employers that have adopted this Plan at any particular time and shall be
       applied as though all of such Employers constituted a single employer.

 2.11  "EMPLOYMENT" shall mean service of an Employee with the Employers.

 2.12  "ERISA" refers to the Employee Retirement Income Security Act of 1974, as
       from time to time amended.

 2.13  "FIELD SALES AGENT" shall refer to an employee who represents Combined
       Insurance Company of America (or any Subsidiary thereof) as an insurance
       agent in the Superior Policy Division of such company and who is under an
       employment contract with the Company denominating him as a
       representative, sales manager, territory manager, district manager, state
       manager, or other comparable title.

 2.14  "FINAL AVERAGE EARNINGS" shall mean the average of a Participant's Annual
       Earnings paid to him by the Employers for service during the highest five
       consecutive calendar years of the last ten calendar years of Employment
       immediately preceding his retirement date or his Termination Date;
       provided, however, that if he was not an Employee during any five
       consecutive calendar years during such period, his Final Average Earnings
       shall be the average of his Annual Earnings during the five calendar
       years (or lesser period if he was not an Employee for such five calendar
       years) immediately preceding the calendar year he was last an Employee.

       "Final Average Earnings A" shall be an amount determined in the same
       manner as Final Average Earnings, except that Annual Earnings during a
       Participant's highest five consecutive calendar years, whether before
       1993 or after 1992, shall

                                      204

                                                                   Exhibit 10(H)
                                                                   page 14 of 91

       be computed solely on the basis of Section 2.02(a) without reference to
       Section 2.02(b).

 2.15  "HIGHLY COMPENSATED EMPLOYEE" shall include an Employee who received
       compensation in excess of $75,000, received compensation in excess of
       $50,000 and was in the top-paid group, or was an officer and received
       compensation greater than $45,000 (all amounts as adjusted for increases
       in the cost of living per Section 14.6), either (i) in the current year
       while a member of the 100 employees paid the greatest compensation or
       (ii) in the preceding year.  The term "compensation" means compensation
       under Section 13.05, and shall include reductions described in Sections
       3.03 and 3.04 of the Aon Savings Plan or for cafeteria plans under
       Section 125 of the IRC.  The following rules shall apply:

       (a) Five-percent owner. Such term shall also include an employee who was
           a five-percent owner (as defined at Section 16.2(b)) at any time
           during either the preceding year or the current year.

       (b) Top-paid group. The "top-paid group" is the group consisting of the
           top 20 percent of employees ranked on the basis of compensation paid
           during the year. For purposes of determining the number of employees
           in the top paid group (but not for purposes of identifying the
           particular employees therein), or the number of officers taken into
           account under Subsection (c), below, there shall be excluded those
           employees who have not completed six months of service; employees who
           normally work either less than 17 1/2 hours per week or not more than
           six months during any year; employees who have not attained age 21;
           and except to the extent provided in regulations, employees included
           in a unit of employees covered by a collective bargaining agreement.

       (c) Officers. The highest paid officer shall always be treated as a
           Highly Compensated Employee; otherwise the number of officers so
           treated shall not exceed the lesser of (i) 50 employees or (ii) the
           greater of three employees or 10 percent of the employees.

       (d) Family members. Any individual who is a member of the family (i.e.,
           the spouse, and lineal ascendants or descendants and their spouses)
           of a Highly Compensated Employee who is either a five-percent owner
           or one of the ten most highly compensated employees shall not be
           considered a separate

                                                                   page 15 of 91
 
          employee and his (or her) compensation (and any applicable
          contribution or benefit on behalf of such individual) shall be treated
          as if it were paid to (or on behalf of) such Highly Compensated
          Employee. This rule shall apply in determining the compensation of (or
          any contributions or benefits on behalf of) any employee for purposes
          of any Section of the IRC with respect to which a Highly Compensated
          Employee is defined by reference to IRC Section 414(q) (the provisions
          of which are set forth in this Section), except as provided in
          regulations and except in determining the portion of the compensation
          of a Participant which is under the integration level for purposes of
          IRC Section 401(l).

      (e) Former employees. A former employee shall be treated as Highly
          Compensated Employee if he was a Highly Compensated Employee either
          (i) when he separated from service or (ii) at any time after attaining
          age 55.

      (f) Nonresident Aliens. For purposes of this Section, employees who are
          nonresident aliens and who receive no earned income (within the
          meaning of Section 911(d)(2) of the IRC) from the Company which
          constitutes income from sources within the United States shall not be
          treated as employees.

      (g) Simplified Method for Determining Highly Compensated Employees. If an
          election by the Company under this Subsection applies to any year, in
          determining whether an employee is a Highly Compensated Employee for
          such year the first sentence of this Section shall be applied by
          substituting "$50,000" for "$75,000," and the $50,000 test for the 
          top-paid group shall not apply. Such election shall not apply to any
          year unless at all times during such year, the Company maintained
          significant business activities (and employed employees) in at least 2
          significantly separate geographic areas, and the Company satisfies
          such other conditions as the Secretary of the Treasury may prescribe.

      (h) Coordination with Other Provisions. Section 13.02 shall be applied
          before the application of this Section 2.15.

 2.16  "HOURS OF SERVICE" in respect to an Employee shall refer to the hours for
       which the Employee is directly or indirectly paid, or entitled to
       payment, for the performance of duties or for a period of time during
       which no duties are

                                      206

                                                                   page 16 of 91
 
       performed during the applicable computation period and such hours shall
       include any hours for which back pay, irrespective of mitigation of
       damages, has either been awarded or agreed to; provided, however, no more
       than 501 Hours of Service shall be credited to an Employee on account of
       any single continuous period (irrespective of whether such period occurs
       in a single computation period, and irrespective of whether the
       employment relationship has terminated) during which the Employee
       performs no duties.  Hours shall not be credited for payments made or due
       under a Plan maintained solely for the purpose of complying with
       applicable workman's compensation, unemployment compensation or
       disability insurance laws, or for a payment which solely reimburses an
       Employee for medical or medically related expenses incurred by such
       Employee.  In those instances where payroll or other Company records do
       not reflect the actual number of hours worked by an Employee, such
       Employee shall be credited with 45 Hours of Service for each calendar
       week that he would be required to be credited with at least one Hour of
       Service under the preceding portion of this Section.  This Section shall
       be applied, in respect to payments for reasons other than the performance
       of duties and in respect to crediting of Hours of Service to a Particular
       computation period, in accordance with the rules set forth in Labor
       Department Regulations Section 2530.200(b)-2(b) and (c), which are
       incorporated herein by reference.

 2.17  "IRC" shall refer to the Internal Revenue Code of 1986, as from time to
       time amended.

 2.18  "LEASED EMPLOYEE" shall refer to an individual, other than an employee of
       the Employer or an affiliated employer (the "recipient employer"), who,
       pursuant to an agreement between the recipient employer and any other
       person (the "leasing organization") has performed services for the
       recipient employer (or the recipient employer and related persons
       determined in accordance with Section 414(n) of the IRC) on a
       substantially full-time basis for a period of at least one year, and such
       services are of a type historically performed by employment in the
       business field of the recipient employer.  Contributions or benefits
       provided a leased employee by the leasing organization which are
       attributable to services performed for the recipient employer shall be
       treated as provided by the recipient employer.  A leased employee shall
       not be considered an employee of the recipient employer if:

                                                                   Exhibit 10(H)
                                                                   page 17 of 91

       (a) such individual is covered by a money purchase pension plan
           providing:

          (i)  a nonintegrated employer contribution rate of at least ten
               percent of compensation, but including amounts contributed
               pursuant to a salary reduction agreement which are excludible
               from the employee's gross income under Section 125, 402(e)(3),
               402(h), or 403(b) of the Code,

          (ii)  immediate participation, and

          (iii)  full and immediate vesting; and

       (b) leased employees do not constitute more than 20% of the recipient
           employer's non-highly compensated work force, as defined in Section
           414(n)(5)(C)(ii) of the Code.

 2.19  "MAXIMUM OFFSET ALLOWANCE" shall mean the maximum offset allowance for a
       Participant under Section 401(1) of the IRC pursuant to regulations and
       rulings of the Secretary of the Treasury or his delegate.  The Maximum
       Offset Allowance shall be calculated based upon one-half of one percent
       (.5%) of the Participant's Final Average Compensation multiplied by his
       Years of Service, up to but not in excess of 35 Years of Service,
       figuring "Final Average Compensation" so as not to exceed "Covered
       Compensation" based upon the definitions and rules under Section
       1.401(l)-1(c)(7) of Treasury Regulations; provided, however, that Covered
       Compensation shall be the average of the Taxable Wage Bases (as defined
       pursuant to Section 3121(a)(1) of the IRC) for the 35 calendar years
       ending with the last day of the year in which a Participant attains

 2.31  "YEARS OF SERVICE" shall, except as hereinafter provided, refer to a 12-
       month period during which an Employee has not less than 1,000 Hours of
       Service in the employment of the Employers.  For purposes of eligibility

       (a) In the case of an Employee who was a Participant in the Combined
           Pension Plan on December 31, 1975, service prior to January 1, 1976,
           that was not a part of a period of Continuous Service as of December

           1, 1976) shall not be counted, but service that was Continuous
           Service as of December 31, 1975, shall be counted and a fractional
           year of such service in excess of 6 months shall be counted as a full
           Year of Service.

       (b) In the case of an Employee whose employment was terminated before he
           acquired any vested interest who again becomes a Participant by
           reason of reemployment after a 1-Year Break in Service, Years of
           Service prior to such break in service shall not be taken into
           account if the number of consecutive 1-Year Breaks in Service equals
           or exceeds the greater of (a) the aggregate number of such Years of
           Service before the break in service; or (b) five. Such aggregate
           number of Years of Service before such break shall not include any
           Years of Service not taken into account by reason of any prior break
           in service.

       (c) In the event of employment in a bargaining unit described  in Section
           3.02(d), the rules set forth in Section 3.05 shall apply.

       (d) In the event of employment outside the United States or its
           possessions, the rules set forth in Section 3.06 shall apply.

       (e) In the event of employment as a Field Sales Agent the rules set forth
           in Section 3.07 shall apply.

                                                                   page 20 of 91
 
       (f) Solely for the purpose of determining a Participant's vested or non-
           forfeitable interest in his Accrued Retirement Income, and subject to
           the limitations of subsection (f) of this section, an Employee shall
           be deemed to have earned a Year of Service for each calendar year
           prior to the date he became an Employee during all of which he
           rendered services to the Employers as an insurance agent in the
           Superior Policy Division in a capacity other than that of an Employee
           (i.e. an independent contractor) and was compensated with respect to
           such service on a commission basis.

       (g) In the case of an Employee ineligible for participation prior to
           January 1, 1988, because his employment began on or after age 60,
           such Employee's service prior to January 1, 1988, shall be taken into
           account.

 2.32  "1-YEAR BREAK IN SERVICE" shall refer to a 12-month consecutive period
       during which an Employee has not completed more than 500 Hours of
       Service.  For purposes of eligibility under Section 3, computation of
       such 12-month period shall be made with reference to the Employee's
       employment commencement date (or, where appropriate, reemployment
       commencement date) and each anniversary of such date.  For all other
       purposes, it shall coincide with the Plan Year.  For purposes of this
       Section only, Hours of Service shall include up to 501 Hours of Maternity
       or Paternity Leave, to be treated as Hours of Service only in the Plan
       Year in which such absence from work begins if the Employee would be
       prevented from incurring a Break in Service in such Plan Year solely
       because periods of absence are treated as Hours of Service as provided
       under this clause, and in any other case in the immediately following
       Plan Year; provided, however, that such hours shall be figured based upon
       the Hours of Service which otherwise would normally have been credited to
       the Participant but for such absence and eight Hours of Service per day
       shall be credited in any case where such normal crediting of Hours of
       Service cannot be calculated; provided further, that the Trustees may
       require the Participant to furnish such timely information as may
       reasonably be required so as to establish that the absence from work is
       for Maternity or Paternity Leave and to establish the number of days for
       which there was such an absence.  "Maternity or Paternity Leave" shall
       mean an absence from work by reason of pregnancy of the Participant, by
       reason of the birth of a child of the Participant, by reason of placement
       of a child with the Participant in connection with its adoption by him or
       her, or for purposes of caring for such child for a period beginning
       immediately following such birth or placement.

           employers.

 3.03  TERMINATION OF EMPLOYMENT.  Any Participant whose employment with the
       Employers is terminated for any reason whatsoever, shall cease to be

       as an Employee, again become a Participant on the first day of his
       reemployment, provided he meets the requirements of Section 3.02(c) and

                                                                   page 22 of 91
 
       however, he shall not earn Hours of Service during a period of unpaid
       Authorized Leave of Absence except to the extent that may be required by
       federal law governing veterans' reemployment rights or under Section 2.32
       relating to Maternity or Paternity Leave.  The Employers shall provide

       conclusive and binding upon all persons having any interest in the Trust.

           Accrued Retirement Income in the event his employment terminates 
           prior to his Normal Retirement Date.

       (d) His service in such bargaining unit shall in no event be considered
           for the purpose of determining his Normal Retirement Benefit under
           Section 4.01 or his Accrued Retirement Income, it being the express
           intent hereof that his service in such bargaining unit shall be
           counted for the purpose of determining his non-forfeitable percentage
           but not for the purpose of increasing the amount of benefits to which
           such percentage shall apply.

       (e) An Employee who becomes employed in a bargaining unit because of the
           recognition of a representative for such unit shall be deemed to be

           him for service outside the United States shall be disregarded in
           determining his Final Average Earnings.

       (c) His Years of Service outside the United States shall be counted for
           the purpose of determining his vested or non-forfeitable interest in
           his Accrued Retirement Income in the event his employment terminated
           prior to his Normal Retirement Date.

       (d) Except as provided under (e) of this Section, his service outside the
           United States shall in no event be considered for the purpose of
           determining his Normal Retirement Benefit under Section 4.01 or his

           his service outside the United States shall be counted for the
           purpose of determining his eligibility to participate hereunder and
           his non-forfeitable percentage but not for the purpose of increasing
           the amount of benefits to which such percentage shall apply.

       (e) If he is transferred from the United States on a temporary basis, he
           shall be deemed to continue as being employed within the United

           States is temporary, shall be made by the Employer and such
           determination shall be conclusive and binding on all persons having
           any interest in the Trust.

       (g) As used in this Section the term "United States" includes possessions
           of the United States.

           intent hereof that his service as a Field Sales Agent shall be
           counted for the purpose of determining his eligibility to participate
           hereunder and his non-forfeitable percentage but not for the purpose
           of increasing the amount of benefits to which such percentage shall
           apply.

       (a) The Accrued Retirement Income and the vested retirement benefit of a
           Participant shall not be less than his benefit as of December 31,
           1988.

       (b) Except as provided in Section 7.11, in the event a Terminated
           Participant again becomes a Participant his Accrued Retirement Income
           shall be determined as of the date his employment last terminated but
           shall in no event be less than his Accrued Retirement Income at the
           time of any prior termination of employment.

       (c) For a Participant formerly in the LOV Pension Plan (as discussed at
           Section 18.03 and not under the career average formula therein), such
           benefit as described at Section III B.I. thereof but counting
           credited Service only through December 31, 1988 shall be (a) 1.5%
           times final average compensation times years of credited service up
           to 25 years, less (but not

                                                                   page 28 of 91

           65 times years of credited service up to 25 years, plus (c) .5% times
           final average compensation times total years of credited service.

       (d) For a Participant previously in  the MMD Pension Plan (as discussed
           at Section 18.04), such benefit as described at Section 4.1 thereof
           but counting credited service only through December 31, 1988, shall
           be (a) 1.6% times average monthly compensation times years of
           credited service up to 25 years plus .5% times average monthly
           compensation times total years of credited service in excess of 25
           years; less (b) 2.5% times his primary social security benefit at age
           65 times years of credited service up to 25 years; (c) prior to
           Normal Retirement Date the accrued benefit of a participant shall be
           calculated by assuming credited service to Normal Retirement Date and
           then multiplying the excess of (a) over (b) by a fraction the
           numerator of which is the Participant's actual years of credited
           service on December 31, 1988 and the denominator of which is the
           number of years of credited service he would have accrued if his
           employment had continued uninterrupted to his Normal Retirement Date;
           (d) provided, however, that a Participant's accrued benefit shall be
           offset by the amount set forth in Appendix A to the Pension Plan,
           i.e., the actuarial equivalent of his June 30, 1982, account balance
           in the MMD Money Purchase Pension Plan, but said offset shall not
           exceed the Participant's accrued benefit figured as set forth at (c)
           but reduced by substituting "May 1, 1982" for "December 31, 1988".

 5.04  EARLY COMMENCEMENT ELECTION.  A Terminated Participant whose employment
       is terminated prior to his Normal Retirement Date may elect to have his
       deferred vested retirement benefit commence on the fifteenth (15th) day
       of any month after his 55th birthday, in which case he will be entitled
       to a vested retirement benefit computed under Section 5.02 but reduced as
       follows, if at all, for each year payable prior to the fifteenth (15th)
       day of the month next following his Normal Retirement Date to reflect the
       early commencement of such benefits:

       (a) For a vested retirement benefit commencing on or after the fifteenth
           (15th) day of the month next following his Normal Retirement Date,
           there shall be no reduction in the Terminated Participant's vested
           retirement benefit.

       (b) For a vested retirement benefit commencing on or after the fifteenth
           (15th) day of the month next following his sixtieth (60th) birthday
           but prior to the date sixty (60) months thereafter, there shall be a
           reduction in the Terminated Participant's vested retirement benefit
           of four percent (4%) for each year or portion thereof payable prior
           to the fifteenth (15th) day of the month next following his Normal
           Retirement Date.

       (c) For a vested retirement benefit commencing on or after the fifteenth
           (15th) day of the month next following his fifty-fifth (55th)
           birthday but prior to the date sixty (60) months thereafter, there
           shall be an additional reduction in the Terminated Participant's
           vested retirement benefit of six percent (6%) for each year or
           portion thereof payable prior to the fifteenth (15th) day of the
           month next following his sixtieth birthday.

       (d) Any early vested retirement benefit for a Participant as figured
           above shall not be less than the sum of the following two amounts:
           (i) his vested retirement benefit as of December 31, 1988, reduced
           under the prior reduction formula in effect on such date, plus (ii)
           his vested retirement benefit calculated under Section 5.01 for
           service after December 31, 1988 (but taking all service into account
           in figuring the 35-year cap under Sections 2.19 and 4.01(c)) reduced
           under the current formula set forth above.

       For Employees of Combined Life Insurance Company of New York the reduced
       vested retirement benefit payable under this Section shall in no event
       exceed the benefit payable under the rules and regulations of the New
       York State Insurance Department.

 5.05  CHANGE IN TOP-HEAVY STATUS.  If the Plan becomes subject to Section 17
       and subsequently ceases to be such, the vesting schedule in Section 17.04
       shall continue to apply in determining the amount of monthly vested
       retirement benefit of any Participant who had at least three Years of
       Service as of December 31st in the last Plan Year of top-heaviness.  For
       other Participants, said schedule shall apply only to their accrued
       benefit as of such December 31st.

                          SECTION 7 - FORM OF PAYMENTS


 7.01  NORMAL FORM OF PAYMENT.  Except as provided in Section 7.03, the normal
       form of payment of any monthly retirement benefit shall be a straight
       life annuity commencing on the date indicated in Section 4 or 5 (as may
       be applicable).

 7.02  120 PAYMENT CERTAIN OPTION.  Anything herein contained to the contrary
       notwithstanding, in every instance in which monthly retirement benefits
       are payable to a Retired or Terminated Participant under Section 4 or 5
       he may elect to receive such retirement benefits as a life annuity with
       120 payments certain.  In any such instance, the monthly retirement
       benefit shall be reduced to the actuarial equivalent of the straight life
       annuity provided by the normal form.  An election under this Section must
       be filed with the Committee not more than 90 days before retirement
       benefits are to commence.  If the Retired or Terminated Participant dies
       prior to the day he is entitled to receive his first monthly payment, the
       election under this Section shall be of no effect and no payments shall
       be made to his Beneficiary.  All distributions under this Section shall
       be subject to Section 7.13.

 7.03  PAYMENT IN QUALIFIED JOINT AND SURVIVOR FORM.  Notwithstanding the
       provisions of Sections 7.01 and 7.02, if a Participant is legally married
       under the laws of any jurisdiction on the date retirement benefits
       described in Section 4 or 5 are to commence, then, in lieu of the form
       and amount of retirement benefit provided by Section 7.01 or 7.02, the
       retirement benefit of such Participant shall be paid in the form of a
       Qualified Joint and Survivor Annuity (as defined below) with the spouse
       of such Participant unless the Participant and his spouse have elected,
       as provided in Section 7.06, to have his retirement benefits paid to him
       pursuant to Sections 7.01, 7.02, 7.04 or 7.05. For the purposes of this
       Plan, the term "Qualified Joint and Survivor Annuity" means an annuity
       for the life of the Participant with a survivor annuity for the life of
       his spouse which is equal to one-half of the amount of the annuity
       payable during the joint lives of the Participant and his spouse and
       which is actuarially equivalent ot the annuity for the life of the
       Participant which he would otherwise be entitled to receive under the
       normal form.

                                                                   page 32 of 91
 
 7.04  ALTERNATE JOINT AND SURVIVOR FORM.  In addition to the 50% Qualified
       Joint and Survivor Annuity form under Section 7.03 for the Participant
       and his spouse, a Participant may elect a joint and survivor form with a
       survivor annuity of 50% (for a contingent annuitant other than the
       spouse), 75% or 100% of the annuity payable during the joint lives of the
       Participant and his designated contingent annuitant. If the specified
       fraction is 75% or 100%, evidence of the Participant's good health must
       be submitted to the Committee if the annuity starting date is prior to
       the Participant's Normal Retirement Date.  Spousal consent under Section
       7.14 shall not be required unless the contingent annuitant is a person
       other than the spouse.


 7.05  SOCIAL SECURITY ADJUSTMENT OPTION.  In order that a Participant who
       retires under the Plan, prior to the earliest date upon which his primary
       insurance benefits may commence under the Social Security Act, may
       receive a more level income where the monthly lifetime annuity payable
       under Section 7.01 is taken together with the Participant's estimated
       primary insurance benefit under the Social Security Act commencing at age
       62, such Participant may elect to convert a portion of his lifetime
       annuity to an actuarial equivalent temporary annuity.  The temporary
       annuity shall provide for monthly payments, commencing at the
       Participant's retirement date, provided that he is then living, and
       terminating with the monthly payment next preceding the earlier of (i)
       the date of the Participant's death or (ii) age 62.   Such election may
       be made by filing a proper written authorization with the Committee
       before the date upon which the annuity payments are to commence to the
       Participant.

 7.06  ELECTION NOT TO RECEIVE QUALIFIED JOINT AND SURVIVOR ANNUITY.  A
       Participant, Retired Participant or Terminated Participant may elect to
       have his retirement benefits paid to him pursuant to Sections 7.01, 7.02,
       7.04 or 7.05 instead of the Qualified Joint and Survivor Annuity form
       under Section 7.03. Any such election shall be made in writing and filed
       with the Committee on such form as the Committee may determine, subject
       to spousal consent under Section 7.14, and shall not be effective unless
       filed with the Trustees within 90 days of the date retirement benefits
       commence.

 7.07  REVOCATION OF ELECTION NOT TO RECEIVE QUALIFIED JOINT AND SURVIVOR
       ANNUITY.  A Participant, Retired Participant or Terminated Participant,
       or his spouse, who has

                                      223

                                                                   Exhibit 10(H)
                                                                   page 33 of 91
 
       elected not to receive his retirement benefits in the Qualified Joint and
       Survivor Annuity form, as provided in Section 7.06, may revoke such
       election at any time before retirement benefits commence.

 7.08  SURVIVING SPOUSE BENEFIT.  In the event of the death of a Participant,
       including a Retired Participant or a Terminated Participant, prior to his
       annuity starting date and after he has either attained his Normal
       Retirement Date under Section 4 or has earned a vested retirement benefit
       under Section 5, the surviving spouse of such deceased Participant shall
       be entitled to receive a survivor annuity.  This survivor annuity shall
       be in the amount that would have been payable under Section 7.03 if the
       decedent had retired with a Qualified Joint and Survivor Annuity
       thereunder on the day before his death; provided, however, that if the
       Participant dies prior to age 55 the survivor annuity shall not be
       payable until the date he would have attained age 55, calculated as if
       the Participant had separated from service on the date of death, survived
       to age 55, and retired with a Qualified Joint and Survivor Annuity on the
       day before his death.  Commencement of the surviving spouse benefit shall
       be delayed beyond the date when it would otherwise commence if the spouse
       so elects in writing, but not beyond the date on which the Participant
       would have attained age 70-1/2 and only if Section 7.07 does not apply.

 7.09  LUMP SUM CASH OUT.  In the event the actuarial equivalent of any monthly
       benefit pursuant to any of the provisions of this Plan expressed as a
       single sum is $3,500 or less, the Committee shall direct the Trustee,
       upon termination of the Participant's employment, to pay to the person
       entitled to such monthly benefit, in a single sum, the amount of such
       actuarial equivalent.  If the payee is a Participant, any benefit that
       may hereafter become payable to him because of subsequent service as an
       Employee shall be reduced by the present value of the accrued benefit
       which was paid to him pursuant to this Section or shall be determined by
       disregarding the Years of Service with respect to which he has received
       payment, the method to be used to be the one which results in the lesser
       benefit.

 7.10  USE OF ANNUITY POLICY.  At such time as a retirement benefit becomes
       payable under this Plan, the Committee may, in its sole discretion,
       provide for the payment of such benefit by directing the Trustee to
       obtain an annuity policy from an insurance company that will provide the
       retirement benefit that is payable and

                                                                   Exhibit 10(H)
                                                                   page 34 of 91
 
       payment pursuant to the terms of any said policy shall be deemed to be
       payment pursuant to the terms of this Plan.  The Trustee may retain
       ownership of any such policy or assign it to the Participant (or his
       surviving spouse, if applicable) and upon such assignment all further
       obligation to make payments pursuant to the terms of this Plan shall
       terminate.  Any annuity policy obtained after July 31, 1983, shall be
       issued on a unisex basis and all the terms and conditions under any such
       contract, including benefits, premiums, options, loan values and cash
       surrender values, shall be the same for both male and female.  Before any
       annuity policy is assigned by the Trustee it shall cause such policy to
       be made nontransferable by any person other than the Trustee.

 7.11  RETURN TO WORK.

       (a) Except as provided below, the retirement benefits of an Employee
           receiving retirement benefits pursuant to Section 4 or 5 and rehired
           by a corporation which is a member of the same controlled group of
           corporations under Section 13.02 as the Employer as of the time
           benefits commenced, shall be suspended or shall continue to be
           suspended only for the calendar month in which the fifteenth (15th)
           day of the month next following his fifty-fifth (55th) birthday falls
           and calendar months thereafter, in which he completes 40 or more
           Hours of Service.

       (b) An Employee may request, and the Committee within a reasonable amount
           of time will render, a determination of whether specific contemplated
           employment would result in suspension of benefits.  Requests for
           status determination shall be considered in accordance with the
           procedure under Section 13.04 for affording a review of the status
           determination.

       (c) No payment shall be withheld pursuant to this Section unless the
           Committee notifies the Employee, by personal delivery or first class
           mail, during the first calendar month in which the Plan withholds
           payments, that his benefits are suspended.  Such notification shall
           contain a description of the specific reasons why benefit payments
           are being suspended, a general description of this Section relating
           to the suspension of payments, a copy of this Section and Section
           7.13, and a statement to the effect that applicable Department of
           Labor regulations may be found in Section 2530.203-3 of Title 29 of
           the Code of Federal Regulations. In addition, the suspension
           notification shall inform

                                                                   page 35 of 91
 
           the Employee of the procedure under Section 13.04 for affording a
           review of the suspension of benefits.

       (d) An Employee rehired prior to his Normal Retirement Date may earn
           additional Years of Service subsequent to his return to work and
           until he retires on or after his Normal Retirement Date. Such period
           shall be taken into account in figuring his Normal Retirement Benefit
           or his vested retirement benefit, as may be applicable.

       (e) Benefits suspended under this Section shall resume (or shall begin,
           in the case of a working Employee who continues in employment after
           the fifteenth (15th) day of the month next following his fifty-fifth
           (55th) birthday and who has completed 40 or more Hours of Service per
           month thereafter as set forth in Subsection (b), above) no later than
           the first day of the third calendar month after the calendar month in
           which the Employee ceases to be subject to suspension of his benefits
           hereunder. The initial payment shall include the payment scheduled to
           occur in the calendar month when payments resume (or begin) and shall
           include any amounts withheld during the period between cessation of
           employment (or the beginning of a calendar month with less than 40
           Hours of Service as provided at Section 7.12, as the case may be) and
           the resumption of payments. The full amount of such initial payment
           may be offset against the amount of any prior retirement benefits
           erroneously paid to the Employee after he had become subject to this
           Section, and subsequent benefit payments may be offset in the amount
           of 25% of the amount otherwise due, until the amount of such
           overpayment has been completely recovered.

 7.12  WHEN PARTICIPANT DEEMED RETIRED.  If a Participant continues to be
       employed after the fifteenth (15th) day of the month next following his
       fifty-fifth (55th) birthday but in any calendar month completes less than
       40 Hours of Service, he shall, for the purposes of this Plan, be deemed
       to have retired on the first day of the month in which such event took
       place; provided, however, that the rules of Section 7.11 shall continue
       to apply in respect to any subsequent month in which he completes 40 or
       more Hours of Service.

                                                                   page 36 of 91
 
 7.13  GENERAL PROVISIONS GOVERNING DISTRIBUTIONS.  Distributions to a
       terminated or retired Participant or Beneficiary of a deceased
       Participant pursuant to Section 4 or Section 5 shall be governed by the
       following:

       (a) Distributions (including distributions under any contract) made in
           periodic installments (which may be increased or accelerated) to a
           Retired Participant shall commence not later than April 1st of the
           calendar year following the calendar year in which he attains age 
           70-1/2.

       (b) Distributions made in periodic installments shall be made either:

          (i)  over the life of the Participant or over the joint lives of the
               Participant and his Designated Beneficiary; or

          (ii) over a period certain not extending beyond the life expectancy of
               the Participant or the life expectancy of the Participant and his
               Designated Beneficiary.

       (c) Where distribution of the Participant's interest has begun under
           Section 7.13(b) and the Participant dies before his entire interest
           has been distributed to him, the remaining portion of such interest
           will be distributed at least as rapidly as under the method of
           distributions being used under Section 7.13(b) as of the date of his
           death.

       (d) If a Participant dies before the distribution of his interest has
           begun under Section 7.13(b), the entire interest of the Participant
           will be distributed within five years after his death except as
           described below:

          (i)  If any portion of the Participant's interest is payable to (or
               for the benefit of) a Designated Beneficiary, such portion is to
               be distributed over the life of such Designated Beneficiary (or
               over a period not extending beyond the life expectancy of such
               Beneficiary), and such distributions begin not later than one
               year after the date of the Participant's death (or such later
               date as IRC regulations may prescribe), then for purposes of this
               Subsection such portion shall be treated as distributed on the
               date when such distributions began.

                                                                   Exhibit 10(H)
                                                                   page 37 of 91
 
          (ii) If such Designated Beneficiary is the surviving spouse of the
               Participant, distributions need not begin until the date on which
               the Participant would have attained age 70-1/2.  If the surviving
               spouse dies before distributions to such surviving spouse begin,
               Section 7.13(d) shall be applied as if the surviving spouse were
               the Participant.  Any amount paid to a child shall be treated as
               if it had been paid to the surviving spouse if such amount will
               become payable to the surviving spouse upon such child reaching
               majority (or other designated event permitted under IRC
               regulations).

       (e) The term "Designated Beneficiary" means any individual designated as
           a Beneficiary by the Participant.

       (f) Notwithstanding the provisions of Subsection (a) hereof, distribution
           to a Participant who has terminated his service, or who is a 5% owner
           [as defined in Section 17.02(b)] at any time during the 5-Plan-Year
           period ending in the calendar year in which he attains age 70-1/2,
           shall commence not later than the 1st day of April of the  calendar
           year following the calendar year in which he attains age 70-1/2. If a
           Participant who has not terminated his service subsequently becomes a
           5% owner after the calendar year in which he attains age 70-1/2, then
           distribution shall commence by April 1st of the calendar year
           following the Plan Year during which he became a 5% owner. Effective
           January 1, 1989, distribution to a Participant shall commence by
           April 1st of the calendar year following the calendar year in which
           he attains age 70-1/2, without regard to whether he has terminated
           his service; provided, that this rule shall not apply to a
           Participant age 70-1/2 or over on January 1, 1988 unless he has been
           a 5% owner at any time during the Plan Year ending during the
           calendar year when he attained age 66-1/2 or any subsequent Plan
           Year, nor shall it apply to any benefits with respect to which a
           designation is in effect as described in Section 7.13(h).

       (g) If any contract or annuity policy on the life of a terminated,
           deceased or retired Participant is distributed, such contract or
           annuity policy shall be endorsed to provide for payments thereunder
           in accordance with the preceding provisions of this Section.

                                                                   page 38 of 91
 
       (h) The foregoing provisions of this Section 7.13 shall not apply to
           distributions under a plan of distribution designated by a
           Participant in writing prior to January 1, 1984, which was
           permissible under the provisions of this Plan as in effect prior to
           the Amendment adding the provisions of the Tax Equity and Fiscal
           Responsibility Act of 1982.

       (i) Distribution to a Participant (or his Beneficiary) whose vested
           accrued benefit has a present value of $3,500 or less shall be made
           as soon as administratively convenient.

       (j) If the Beneficiary of the Participant is not his spouse the form of
           distribution must be one whereunder the present value of the
           retirement benefit payments projected to be made to the Participant,
           while living, is more than 50 percent of the present value of the
           total payments projected to be made to the Participant and the
           Participant's Beneficiary; provided, however, that this requirement
           shall be interpreted so as to comply with the incidental benefit rule
           of the IRC and the rules and regulations thereunder.

       (k) Except as provided in regulations, the provisions of IRC Section
           Section 401(a)(9) are hereby incorporated by reference to the extent
           not set forth in this Section.

 7.14  SPOUSAL CONSENT.  Any election by the Participant under Section 7.06
       shall not take effect unless the spouse consents in writing to such
       election.  Such consent must be given within the 90 day election period
       under Section 7.06, must acknowledge the effect of the election or
       designation, shall be to a specific Beneficiary and to a specific form of
       benefit, and be witnessed by a Plan representative or a notary public.
       Any consent shall be effective only as to such spouse.  Such election
       shall take effect without the spousal consent only if it is established
       to the satisfaction of a Plan representative that the consent may not be
       obtained because there is no spouse, because the spouse cannot be
       located, or because of such other circumstances as the Secretary of the
       Treasury may by regulations prescribe.

 7.15  NOTICE.  The Trustees shall deliver a written explanation to each
       Participant or terminated Participant who will become entitled to receive
       vested retirement benefits on or about the date nine (9) months before he
       attains age 55 of the terms and conditions of the Qualified Joint and
       Survivor Annuity form and the

                                                                   page 39 of 91
 
       surviving spouse benefit, including the rights of the spouse under
       Section 7.14, and the effect of electing or not electing such a form of
       payment.  The explanation shall include a general description of the
       eligibility conditions and other material features of the optional forms
       of benefit, including the relative values of such optional forms with the
       interest rate used in calculating such values.  Notwithstanding the
       provisions of Sections 7.06 and 7.07, the period for such election or
       revocation thereof shall not expire until at least ninety (90) days after
       such notice has been given.  Any Participant who has not had an election
       under Section 7.06 made available may elect (or his personal
       representative may elect in the event of his death) to receive the
       balance of his benefits in a form other than that of a Qualified Joint
       and Survivor Annuity or surviving spouse benefit at any time until ninety
       (90) days after notice of the availability of such election is given to
       such Participant (or to his personal representative).

 7.16  JOINT AND SURVIVOR ANNUITIES AND SURVIVING SPOUSE BENEFITS TO FORMER
       PARTICIPANTS.  Effective August 23, 1984, a Participant (including a
       Terminated Participant) who had at least one Hour of Service on or after
       September 2, 1974, to whom Section 205 of ERISA and IRC Section
       401(a)(11) (as in effect on August 22, 1984) would not apply but for this
       Section, to whom the amendments made by Section 103 and 203 of the
       Retirement Equity Act of 1984 dealing with Qualified Joint and Survivor
       Annuities and Surviving spouse Benefits do not apply, whose annuity
       starting date has not occurred as of August 23, 1984, and who is still
       alive as of August 23, 1984, may elect to have the Provisions of Section
       7 as in effect prior to August 23, 1984 apply.  A Participant (including
       a Terminated Participant) who had at least one Hour of Service in any
       Plan Year beginning on or after January 1, 1976, to whom the amendments
       made by Section 103 and 203 of the Retirement Equity Act of 1984 dealing
       with Qualified Joint and Survivor Annuities and Surviving Spouse Benefits
       would not (but for this Section) apply who at the time of his separation
       from service had at least ten  Years of Service under the Plan and had a
       non-forfeitable right at least a portion of his accrued benefit derived
       from Employer contributions, whose annuity starting date has not occurred
       as of August 23, 1984, and who is still alive as of August 23, 1984, may
       elect to have the qualified pre-retirement survivor annuity requirements
       of the amendments made by such Sections 103 and 203 apply.  Any election
       under this Section may be made during the period beginning August 23,
       1984, and ending on the earlier of the Participant's Annuity Starting
       Date or the

                            SECTION 8 - PLAN FUNDING


 8.01  CONTRIBUTIONS. The Employers will make contributions from time to time to
       the Trustee under the Trust Agreement in amounts that are sufficient (as
       determined in accordance with the Plan funding method and policy adopted
       by the  Employer) to provide the benefits provided hereunder and as are
       consistent with the provisions of Part 3 of Title I of ERISA.
       Participants shall not make contributions under the Plan.

 8.02  FORFEITURES.  All forfeitures arising under the Plan will be applied to
       reduce the Employer's contributions thereunder and shall not be used to
       increase the benefits any person would otherwise receive under the Plan.

                                                                   page 42 of 91
 
            SECTION 9 - RIGHTS TO AMEND OR DISCONTINUE CONTRIBUTIONS


 9.01  CONTINUANCE OF CONTRIBUTIONS NOT ASSUMED.  It is the expectation of the
       Employers that they will continue this Plan and the payment of its
       contributions hereunder indefinitely; but continuance of the Plan is not
       assumed as a contractual obligation and the right is reserved to each
       Employer at any time to discontinue its contributions hereunder.

 9.02  RIGHT TO AMEND.  Except as herein limited, the Company, by action of the
       Board, shall have the right to amend this Plan at any time to any extent
       it may deem advisable.  Such amendment shall be stated in an instrument
       in writing approved by the Board.  Upon delivery of such instrument to
       the Committee, this Agreement shall be deemed to have been amended in the
       manner set forth, provided, however, except as may be required to
       maintain this Plan as a qualified Plan under the IRC:

       (a) No amendment shall increase the duties or liabilities of the Trustees
           without their  consent;

       (b) No amendment shall have the effect of vesting in the Employers any
           interest in or control over the Retirement Fund;

       (c) No amendment shall have the effect of depriving the surviving spouse
           or Beneficiary of a then deceased Participant of the right to receive
           the benefits to which such spouse or Beneficiary is entitled;

       (d) No amendment shall have the effect of depriving any then Retired
           Participant or active Participant who has then reached his Normal
           Retirement Date of the retirement income which he is entitled to
           receive;

       (e) No amendment shall have the effect of depriving any Terminated
           Participant of the benefits which he is entitled to receive;

       (f) No amendment shall have the effect of depriving any Participant of
           any benefit he would have been entitled to receive if he had
           terminated his employment immediately prior to such amendment;

                                                                   page 43 of 91
 
       (g) No amendment shall have the effect of decreasing the accrued benefit
           of Participant other than an amendment described in IRC Section
           412(c)(8), or Section 4281 of ERISA. For purposes of the preceding
           sentence a plan amendment which has the effect of (i) eliminating or
           reducing a subsidy or an early retirement benefit (as defined in
           regulations), or (ii) eliminating an optional form of benefit with
           respect to benefits attributable to service before the amendment,
           shall be treated as reducing accrued benefits. In the case of a
           retirement-type subsidy, the preceding sentence shall apply only with
           respect to a Participant who satisfies (either before or after the
           amendment) the pre-amendment conditions for the subsidy. This
           Paragraph shall not apply, to the extent provided by regulations, to
           a plan amendment described in clause (ii) (other than a plan
           amendment having an effect described in clause (i)).

 10.01 TERMINATION BY EMPLOYER.  Unless otherwise terminated, as provided in
       paragraphs (a), (b), and (c), of this Section or Section 10.03, this Plan
       shall continue in perpetuity, or for such time as may be necessary to
       accomplish the purpose or which it is created.  This Plan shall terminate
       upon the happening of any of the following events:

       (a) The Company, by appropriate resolution of its Board, elects to
           terminate this Plan;

       (b) An Employer shall elect to terminate its participation in the Plan or
           shall be judicially declared bankrupt or insolvent, or in the event
           of dissolution, merger, or consolidation of the Employer without
           provision for continuing this Plan; provided, however, in the event
           of dissolution, merger, or consolidation of the Employer, provision
           may be made by its successor for continuing this Plan and the
           substitution of such successor or successors for the Employer
           hereunder, in which event this Plan shall continue in full force and
           effect and further provided that termination shall be limited as
           described under Section 15.03.

       (c) There is a complete termination of this Plan within the meaning of
           Section 411(d)(3) of the IRC.

 10.02 DISTRIBUTION ON COMPLETE TERMINATION.  In the event this Plan shall
       terminate for any of the reasons set forth in Section 10.01(a) or (c),
       the Trustees shall, after payment of all expenses of liquidation,
       distribute the Retirement Fund in the manner and order set forth in
       Section 4044 of ERISA.  This Trust shall continue as a liquidation trust
       until final distribution of all assets.

 10.03 TERMINATION BY PENSION BENEFIT GUARANTY CORPORATION.  In the event this
       Plan is terminated by reason of proceedings instituted by the Pension
       Benefit Guaranty Corporation under Section 4042 of ERISA, the Retirement
       Fund shall be distributed pursuant to the provisions of Section 402 of
       ERISA.

 10.04 VESTING UPON TERMINATION.  Except as provided in Section 11, upon the
       termination or partial termination of this Plan the rights of all
       affected Participants to benefits accrued to the date of termination or
       partial termination, to the extent funded as of such date, shall be non-
       forfeitable.

        SECTION 11 - BENEFITS IN THE EVENT OF EARLY TERMINATION OF PLAN


 11.01 PARTICIPANTS. Notwithstanding any provision in this Agreement to the
       contrary, the benefits provided by the Company's contributions for
       Participants whose anticipated annual retirement benefit provided by such
       contributions will exceed $1,500, but applicable only to the twenty-five
       highest paid Employees as of December 31, 1988 (including any such

       later become Participants) shall be subject to the conditions hereinafter
       set forth.

 11.02 MAXIMUM BENEFIT.  Such benefits shall be paid in full which have been
       provided by the Company's contributions not exceeding the largest of the
       following amounts:

       (a) The Company contributions (or funds attributable thereto) which would
           have been applied to provide the benefits for the Employee of this
           Plan, as it existed prior to January 1, 1989, and as if the Plan had
           been continued without change.

       (b) $20,000

       (c) An amount equal to 20% of the first $50,000 of the Participant's
           annual Compensation multiplied by the number of years between
           December 31, 1988, and (A) the date that the Plan terminates, or (B)
           if benefits become payable to a Participant described in Section
           11.01 within ten years after December 31, 1988, the date the benefits
           of such Participant first become payable (if before the date of
           termination of this Plan), or (C) if benefits become payable to a
           Participant described in Section 11.01 after December 31, 1988, and
           if the full current costs of the Plan for the ten years starting

               1563(e)(3)), a dollar amount which equals the present value of
               the benefit guaranteed for such Participant under Section 4022 of
               ERISA, as amended, or if the Plan has not terminated, the present
               value of the benefit that would be guaranteed if the Plan
               terminated on the date the benefit commences determined in
               accordance with regulations of the Pension Benefit Guaranty
               Corporation; or

          (ii) for a Participant not within Paragraph (i), above, a dollar
               amount which equals the present value of the maximum benefit
               described in Section 4022(b)(3)(B) of ERISA, as amended
               (determined on the date the Plan terminates or on the date
               benefits commence, whichever is earlier) without regard to any
               other limitations in Section 4022 of ERISA.

 11.03 LIMITATION ON BENEFITS.  If (1) this Plan is terminated within ten years
       after December 31, 1988, or (2) the benefits of any of the Participants
       described in Section 11.01 become payable within ten years from December
       31, 1988, the benefits which any of the Participants described in Section
       11.01 may receive from the Company's contributions shall not exceed the
       benefits set forth in Section 11.02.

 11.04 TERMINATION OF EMPLOYMENT.  If a Participant described in Section 11.01
       leaves the employ of the Company or withdraws from participation in this
       Plan, the benefits which he may receive from the Company's contributions
       shall not at any time, within the first ten years after December 31,
       1988, exceed the benefits set forth in Section 11.02.  If, at the end of
       the ten-year period starting December 31, 1988, the full current costs
       for such ten years have not been met, the benefits such Participant may
       receive from the Company's contributions shall not exceed the benefits

       costs of this Plan have been met.

 11.05 DEATH BENEFITS.  These conditions shall not restrict the full payment of
       any insurance, death or survivor's benefits on behalf of a Participant
       who dies while this Plan is in full effect and its full current costs
       have been met.

 11.06 RETIREMENT BENEFITS.  These conditions shall not restrict the current
       payment of full retirement benefits not exceeding those provided by the
       normal form called

       for by this Plan for any Retired Participant while this Plan is in full
       effect and its full current costs have been met.

 11.07 LUMP SUM DISTRIBUTION.  The conditions of this Section shall not restrict
       a lump sum distribution to a Terminated or Retired Participant of the
       benefits he may be entitled to receive, if this Plan is in full effect
       and its full current costs have been met at the time of the distribution
       and he enters into an agreement with the Trustees to the effect that in
       the event

       (a) the Plan terminates before December 31, 1998, or

       (b) a default occurs in the payment of the full current costs of the Plan
           for any Plan Year ending before December 31, 1998

       he (or, in the case of his death, his estate) will repay to the Trustees
       a sum equal to the actuarial equivalent of the amounts by which his
       monthly retirement benefits under the Plan (under the normal form) would
       have decreased during his then remaining lifetime pursuant to the
       provisions of this Section 11.  Such obligation to repay must be
       adequately secured, and if secured by property of the distributes, the
       distributes must agree that if the market value of the property falls
       below a certain percentage of the amount that would then be repayable if
       the Plan were then terminated he will deposit additional property
       necessary to sufficiently increase the value of the property held by the
       depositary.  The agreement need not be secured if the fair market value
       of Plan assets is not less than the actuarial equivalent of all accrued
       benefits (whether or nor forfeitable) expressed as a single sum;
       provided, that the agreement shall provide for security to be provided in
       the future in the event that the fair market value of Plan assets
       subsequently, during the period covered by this Section, falls below the
       actuarial equivalent of all accrued benefits.

 11.08 INTENT. This Section 11 is included in this agreement to conform to the
       requirements of Treasury Regulation Paragraph 1.401-4(c) and shall be
       applied in a manner consistent with such Regulation or any substitute
       therefor but shall cease to be effective at such time as the provisions
       of the Treasury Regulation Paragraph 1.401(c) or any substitute therefor
       are no longer effective or applicable.

                     SECTION 12 - ADMINISTRATIVE COMMITTEE


 12.01 FORMATION AND MEMBERS.  This Plan shall be administered by an
       administrative committee constituted of not less than three (3) and not
       more than seven (7) members.  The Board shall have the right at any time
       and from time to time to appoint the members of the Committee and to
       remove any member of the Committee and appoint a successor member.  Each
       member of the Committee shall serve until such time as he shall resign,
       die, or be removed by the Board and until his successor is appointed.  In
       the event of the death, resignation or removal of any member acting
       hereunder, the Board may appoint a successor to fill such vacancy and
       such successor member, upon accepting such appointment by an instrument
       in writing delivered to the Company, shall without further action, become
       vested with all the rights, powers, discretion and duties of a member of
       the Committee with like effect as if originally named as a member
       hereunder.  Each member of the Committee shall have the right at any
       time, by ten (10) days written notice to the other members then acting
       hereunder, and to the Company, to resign as a member hereunder.

 12.02 CHAIRMAN AND SECRETARY.  The Committee shall appoint a Chairman from
       among the members of the Committee and the Chairman shall preside at all
       meetings of the Committee, and shall have the right to vote on any matter
       to be determined by the Committee.  The Committee shall also appoint a
       Secretary to the Committee, who need not be a member of the Committee,
       who shall keep an accurate record of all determinations of the Committee
       and perform such other duties as may from time to time be assigned to him
       by the Committee or the Chairman of the Committee.

 12.03 ACTIONS OF THE COMMITTEE.  All actions of the Committee shall be by
       majority vote of the entire Committee.  No formal meetings need be called
       or held by such Committee if a majority of the then members of the
       Committee shall authorize and approve, by an instrument in writing, any
       action or decision agreed upon by such majority.

 12.04 EXECUTION OF INSTRUMENTS.  The Committee may designate any one or more of
       its members, or its Secretary, to sign any document, instrument or paper
       on behalf of the entire Committee.

 12.05 REPORTS TO THE BOARD.  The Committee shall furnish such reports and other
       information as may be required from time to time by the Board.

 12.06 ADMINISTRATION OF THE PLAN.  The Committee may, from time to time,
       establish rules and procedures for administration of the Plan not
       inconsistent with the Plan's provisions, and administer the Plan in
       accordance with such provisions and such rules and procedures.  The
       Committee shall have the exclusive right and discretionary authority to
       construe the terms and provisions of the Plan, including without
       limitation, the power to construe or interpret disputed, ambiguous or
       uncertain terms, and such other powers as may be necessary to carry out
       the provisions of the Plan.  The Committee shall also have the
       discretionary authority to determine all questions relating to the
       eligibility of Employees to participate in the benefits of the Plan and
       the amount of such benefits, and resolve all questions pertaining to the
       administration, interpretation and application of the Plan provisions.
       Actions taken in good faith by the Company, the Committee or an Employer
       shall be conclusive and binding on all interested parties as to all
       questions of interpretation and application under this Plan and as to all
       other matters arising out of the administration thereof, and shall be
       given the maximum possible deference allowed by the law.  The Committee
       shall issue such directions to the Trustee as may from time to time be
       necessary to authorize the Trustee to make the payments provided for by
       this Plan.

 12.07 LIABILITY OF MEMBERS.  To the extent permitted by law, no member of the
       Committee shall ever be liable for any act or default of any predecessor
       member nor for any loss sustained through any error of judgment, but
       shall only be liable for his own willful default.  No successor member
       acting hereunder shall be under any duty to examine into or take any
       action with reference to the prior action of any prior Committee acting
       hereunder.  The Company shall indemnify and save harmless each member of
       the Committee and the Secretary to the Committee from the effects and
       consequences of his actions and conduct in his official capacity, except
       to the extent that such effects and consequences flow from his own
       willful conduct.

 12.08 ALLOCATION OF DUTIES.  The Committee, by its action, may allocate its
       fiduciary responsibilities among its members, and may designate persons
       other than its members to carry out its fiduciary responsibilities.  The
       Committee, individual members of the Committee allocated specific
       fiduciary responsibilities, and

       persons other than members of the Committee designated to carry out
       specific fiduciary responsibilities may employ one or more persons to
       render advice with respect to their responsibilities.  If the Committee
       has allocated a specific fiduciary responsibility among its members, or
       has designated persons other than its members to carry out a specific
       fiduciary responsibility, it shall do the following things:  (1) it
       shall make as a condition of such allocation or designation the fact that
       the Committee may terminate the allocation or designation at will; and
       (2) it shall report such allocation or designation to the Board who by
       its action, may order that such allocation or designation be terminated
       in which case it shall be done as soon as practicable.

 12.09 INVESTMENTS.  The Committee shall have no duty or obligation to supervise
       or control in any way the investments made by the Trustee under the Trust
       Agreement, but all fiduciary responsibility for investing and
       safeguarding the assets of the Plan shall reside solely with such
       Trustee.

                         SECTION 13 - ERISA PROVISIONS


 13.01 SERVICE FOR PREDECESSOR.  To the extent required by regulations that may
       be prescribed by the Secretary of the Treasury or his delegate, service
       for a predecessor shall be treated as service for the Employers.

 13.02 CONTROLLED GROUP.  To the extent required by Section 414(b), (c), (m),
       (n) and (o) of the Internal Revenue Code, all employees of the entities
       described therein shall be treated as employed by a single employer.  If
       an Employee or former Employee becomes employed or was employed by any
       such entity that the Employer is a member of and such other member has
       not adopted this Plan, the following rules shall apply:

       (a) Upon becoming an Employee of the Employer, his prior service in the
           employment of another member of the controlled group shall be
           considered as though it was service for the Employer for the purpose
           of determining when he will become eligible for participation under
           Section 3 and for the purpose of determining his eligibility for a
           vested retirement benefit.

       (b) If he was previously an Employee of the Employers and a Participant
           under this Plan but did not have five Years of Service at the time
           such employment terminated, his subsequent service in the employment
           of another member of the controlled group shall be considered as
           though it was service for the Employers for the purpose of
           determining his eligibility for a vested retirement benefit under
           Section 5.02.

       (c) His service for such other member of the controlled group shall in no
           event be considered for the purpose of determining his Normal
           Retirement Benefit under Section 4.01 or his Accrued Retirement
           Income under Section 5.02, it being the express intent hereof that
           his service for another member of the controlled group that has not
           adopted this Plan shall be counted for the purpose of determining his
           non-forfeitable percentage but not for the purpose of increasing the
           amount of benefits to which such percentage shall apply.

       (d) He shall not be eligible to receive any benefits while employed by
           any other member of the controlled group, except as provided at
           Section 7.12.

                                                                   page 53 of 91
 
       (e) Remuneration paid to such person for services rendered to another
           member of a controlled group shall not be considered in determining
           his Final Average Earnings.

 13.03 MERGER.  This Plan shall not be merged or consolidated with any other
       Plan or the assets held under this Plan shall not be transferred to any
       other Plan, unless each Participant in the Plan would (if the Plan then
       terminated) receive a benefit immediately after the merger, consolidation
       or transfer which is equal to or greater than the benefit he would have
       been entitled to receive immediately before the merger, consolidation or
       transfer (if this Plan had then terminated) .

 13.04 CLAIMS PROCEDURE.  Pursuant to Section 503 of ERISA the following claims
       procedure is established:

       (a) A timely written application for benefits  shall be filed with the
           Committee on a form prescribed by  it.

       (b) if a Claim is denied, in whole or in part, written notice of such
           denial shall be furnished to the applicant setting forth, in a manner
           calculated to be understood by him, the following:

           (i)   The specific reason or reasons for the denial;

           (ii)  A specific reference to pertinent Plan provisions on which the
                 denial is based;

           (iii) A description of any additional material or information
                 necessary for the claimant to perfect the claim and an
                 explanation of why such material or information is necessary; 
                 and

           (iv)  An explanation of the claim review procedure.

       (c) An applicant whose claim has been denied in whole or in part (or his
           duly authorized representative) may appeal such denial to the
           Committee by making a written request for a review and may review
           pertinent documents and submit issues and comments in writing.  A
           written request for review

           must be filed within 120 days of the date an applicant has been
           notified of the denial or partial denial of this claim.

       (d) The decision on review shall be made promptly and within 60 days of
           receipt of the request for review, shall be in writing, and shall
           include specific reasons for the decision, written in a manner
           calculated to be understood by the applicant, and specific references
           to the pertinent Plan provisions on which the decision is based.

 13.05 MAXIMUM ANNUAL BENEFIT.  The annual benefits payable to a Participant
       under this Plan and any other qualified defined benefit plan adopted by
       the Employer shall in no event exceed the lesser of $90,000 (the "dollar"
       limitation) or 100% of the Participant's average compensation for his
       high three consecutive calendar years of participation (the "percentage"
       limitation).  The following rules shall be effective in applying the
       provisions of this Section:

       (a) Both the $90,000 dollar limitation and the 100% percentage limitation
           referred to in the first sentence of this Section shall be adjusted
           for increases in the cost of living in accordance with regulations
           prescribed by the Secretary of the Treasury or his delegate;
           provided, however, that the 100% percent limitation shall be adjusted
           only in the case of adjusting any benefits under this Section, and no
           cost of living adjustments under this Subsection shall be taken into
           account before the year for which such adjustment takes effect.

       (b) If the annual benefit is payable in a form other than as a straight
           life annuity, an adjustment shall be made to the maximum permissible
           annual benefit, in accordance with regulations prescribed by the
           Secretary of the Treasury or his delegates so that it is equivalent
           to the maximum annual benefit payable as a straight life annuity. In
           determining the maximum annual benefit payable any ancillary benefit
           which is not directly related to retirement income benefits shall not
           be taken into account, and that portion of any joint and survivor
           annuity which constitutes a qualified joint and survivor annuity
           under Section 7.03 shall not be taken into account.

       (c) If the retirement income benefit begins before the Social Security
           Retirement Age, the determination as to whether the $90,000 dollar
           limitation referred to in the first sentence of this Section has been
           satisfied shall be made in

                                                                   page 55 of 91
 
           accordance with regulations prescribed by the Secretary of the
           Treasury or his delegate, by reducing the limitation so that such
           limitation (as so reduced) equals an annual benefit (beginning when
           such retirement income benefit begins) which is equivalent to a
           $90,000 annual benefit beginning at the Social Security Retirement
           Age. The reduction shall be made in such manner (as prescribed by the
           secretary of the Treasury or his delegate) as is consistent with the
           reduction for old-age insurance benefits commencing before the Social
           Security Retirement Age under the Social Security Act.

       (d) If the retirement income benefit begins after the Social Security
           Retirement Age, the determination as to whether the dollar limitation
           referred to in the first sentence of this Section has been satisfied
           shall be made in accordance with regulations prescribed by the
           Secretary of the Treasury or his delegate, by increasing the
           limitation so that such limitation (as so increased) equals an annual
           benefit (beginning when such retirement income benefit begins) which
           is equivalent to a $90,000 annual benefit beginning at the Social
           Security Retirement Age.

       (e) For the purpose of adjusting any benefit under Subsection (b) or (c),
           above, the interest rate assumption shall not be less than the
           greater of 5% or the rate specified in the Plan. For purposes of
           adjusting any benefit under Subsection (d), above, the interest rate
           assumption shall not be greater than the lesser of 5% or the rate
           specified in the Plan.

       (f) Notwithstanding the preceding provisions, the benefits payable with
           respect to a Participant shall be deemed not to exceed his limitation
           if they do not exceed $10,000 for the Plan Year, or for any prior
           Plan Year, and the Employer has not at any time maintained a defined
           contribution Plan in which the Participant participated.

          (i)  if a Participant has less than 10 years of participation in the
               Plan, the $90,000 dollar limitation referred to in the first
               sentence of this Section shall be the limitation determined under
               such sentence (without regard to this Subsection (g)), multiplied
               by a fraction --

               (A)  the numerator of which is the number of years (or part
                    thereof) of participation, and

                                                                   page 56 of 91
 
               (B)  the denominator of which is 10.

          (ii)  If a Participant has less than 10 years of service with the
                Employer, the 100% percentage limitation under the first
                sentence of this Section and the $10,000 limitation under
                Subsection (f) shall be adjusted by multiplying such amounts by
                a fraction --

                (A)  the numerator of which is the number of years (or part
                     thereof) of service, and

                (B)  the denominator of which is 10.

          (iii) In no event shall Paragraphs (i) or (ii), above, reduce either
                the dollar limitation or the percentage limitation under the
                first sentence of this Section, or the $10,000 limitation under
                Subsection (f), to an amount less than 1/10 of such limitation
                (determined without regard to this Subsection (g)).

          (iv)  To the extent provided in regulations this Subsection (g) shall
                be applied separately with respect to each change in the benefit
                structure of the Plan.

       (g) In the event a Participant herein is a participant at any time in a
           defined contribution plan maintained by the Employer or a member of a
           controlled group, the sum of the defined benefit plan fraction and
           the defined contribution plan fraction for any year shall not exceed
           1.0 but such limitation may be applied to first reduce benefits under
           this Plan before being applied to reduce annual additions under the
           defined contribution plan. For this purpose the defined benefit plan
           fraction for any year is:

               Projected annual benefit of the Participant under the Plan 
               (determined as of the close of the year)
               -----------------------------------------------------------------
               Lesser of: (a) 1.25 multiplied by the dollar limitation in effect
               for such year ($90,000 for 1987) or (b) 1.4 multiplied by the
               percentage limitation with respect to such individual under

                                                                   page 57 of 91
 
               the Plan for such year (100% of his average total compensation
               for his high 3 years).

          The defined contribution plan fraction for any year is:

               Sum of the annual additions to the participant's account as of 
               the close of the year.
               --------------------------------------------------------------
               The sum of the lesser of the following amounts determined for
               such year and for each prior year of service with the employer:
               (a) 1.25 multiplied by the dollar limitation in effect for such
               year ($30,000 for 1987) or (b) 1.4 multiplied by the percentage
               limitation with respect to such individual under the plan for
               such year (25% of his total compensation). Contributions by a
               Participant to any qualified cost-of-living arrangement (as
               defined under IRC Section 415(k)(2), as amended from time to
               time) under the Plan shall be treated as an annual addition for
               purposes of this Subsection (h).

                                                                   page 58 of 91
 
       (h) At the election of the plan administrator, in applying the defined
           contribution plan fraction under Subsection (h), above, with respect
           to any year ending after December 31, 1982, the denominator of the
           fraction with respect to each participant for all years ending before
           January 1, 1983, shall be an amount equal to the product of such
           denominator under the law in effect for the year ending in 1982
           multiplied by the transition fraction.  The transition fraction means
           a fraction whose numerator is 35% of the compensation of the
           participant for the year ending in 1981 (limited to $51,875) and
           whose denominator is 25% of such compensation (but more than 
           $41,500).

       (i) Provided the Plan satisfied the requirements of IRC Section 415 for
           the last year beginning before January 1, 1983, and pursuant to
           regulations prescribed by the Secretary of the Treasury or his
           delegate, the numerator of the defined contribution plan fraction at
           Subsection (h) may be reduced so that the sum of the defined
           contribution plan fraction and the defined benefit plan fraction does
           not exceed 1.0 for such year.

       (j) In the case of an individual who is a participant before January 1,
           1983, in a defined benefit plan which is in existence on July 1,
           1982, and with respect to which the requirements of Section 415 of
           the IRC have been met for all years, if such individual's current
           accrued benefit under such plan exceeds the limitation of Subsection
           (b) of Section 415 as provided under the first sentence of this
           Section and under Subsections (a) through (g) hereof, then (in the
           case of such plan) for purposes of such IRC Section 415(b), and also
           for purposes of IRC Section 415(e) as provided under Subsections (h)
           through (j), hereof, the limitation of such IRC Section 415(b) with
           respect to such individual shall be equal to such current accrued
           benefit.

           The term "current accrued benefit" means the individual's accrued
           benefit (at the close of the last year beginning before January 1,
           1983) under this Plan, which was in existence on July 1, 1982, when
           expressed as an annual benefit (within the meaning of Section
           415(b)(2) of the IRC as in effect before the amendments made by the
           Tax Equity and Fiscal Responsibility Act of 1982). For purposes of
           determining the amount of any individual's current accrued benefit,
           no change in the terms and conditions of the Plan after July 1, 1982,
           and no cost-of-living adjustment occurring after July 1, 1982, shall
           be taken into account.

                                                                   page 59 of 91
 
       (k) In the case of an individual who was an active Participant in this
           Plan before October 3, 1973, his annual benefit need not be less than
           100% of his annual rate of compensation on the earlier of October 2,
           1973, or the date on which he separated from the service of the
           Employer; provided, that such annual benefit shall not exceed the
           benefit which would have been payable under the terms of the plan on
           October 3, 1973, if his compensation taken into account for any
           period after such date had not exceeded his annual rate of
           compensation on such date; and provided further, in the case of a
           Participant who separated from service prior to October 2, 1973, his
           annual benefit shall in no event be greater than his vested retired
           benefit as of the date he separated from service.

       (l) In addition to other limitations set forth in the Plan and
           notwithstanding any other provisions of the Plan , the accrued
           benefit, including the right to any option benefit provided in the
           Plan (and all other defined benefit plans required to be aggregated
           with this Plan under the provisions of IRC Section 415) shall not
           increase to any amount in excess of the amount permitted under IRC
           Section 415 as amended by the Tax Equity and Fiscal Responsibility
           Act of 1982.

       (m) In determining under which Plan the contributions or other annual
           additions, or benefits, of a Participant should be reduced under this
           Section, the intent is that the order of reduction set forth herein
           is for purposes of guidance only and not obligatory, and that such
           order of reduction as to one Participant may be different from
           another Participant, so as to afford maximum flexibility to the Plan
           in avoiding a violation of the provisions of Section 415 of the IRC.

       (n) For purposes of this Subsection, the term "Social Security Retirement
           Age" means the age used as the retirement age for the Participant
           under Section 216(l) of the Social Security Act, except that such
           section shall be applied without regard to the age increase factor,
           and as if the early retirement age under Section 216(l)(2) of such
           Act were 62.

       (o) In the case of an individual who is a Participant as of January 1,
           1987, the dollar limitation of the Participant shall be equal to his
           Current Accrued Benefit if such Current Accrued Benefit exceeds the
           benefit limitations of this

                                                                   page 60 of 91
 
           Section and of IRC Section 415(b) of the IRC.  The "Current Accrued
           Benefit" shall be the Participant's accrued benefit under the Plan
           when expressed as an annual benefit under IRC Section 415(b)(2),
           determined as if he had separated from service as of December 31,
           1986, but disregarding any changes in the terms and conditions of the
           Plan, or any cost-of-living adjustment, occurring after May 5, 1986.

       (p) Compensation shall include the following items:

          (i)   The Participant's wages, salaries, fees for professional service
                and other amounts received for personal services actually
                rendered in the course of employment with an employer
                maintaining the plan (including but not limited to, commissions
                paid salesmen, compensation for services on the basis of a
                percentage of profits, commissions on insurance premiums, tips
                and bonuses).

          (ii)  For purposes of the prior sentence, earned income from sources
                outside the United States.

          (iii) Amounts described in IRC Sections 104(a)(3), 105(a) and 105(h),
                but only to the extent that these amounts are includable in the
                gross income of the Employee.

          (iv)  Amounts described in IRC Section 105 (d) , whether or not these
                amounts are excludable from the gross income of the Employee
                under that section.

          (v)   Amounts paid or reimbursed by the Employer for moving expenses
                incurred by an Employee, but only to the extent that these
                amounts are not deductible by the Employee under IRC Section 
                217.

          (vi)  The value of a non-qualified stock option granted to an Employee
                by the employer, but only to the extent that the value of the
                option is includable in the gross income of the Employee for the
                taxable year in which granted.

                                                                   page 61 of 91
 
          (vii) The amount includable in the gross income of an Employee upon
                making the election described in IRC Section 83(b).

       (q) Compensation shall not include the following items:

          (i)   Contributions made by the Employer to a plan of deferred
                compensation to the extent that, before the application of the
                IRC Section 415 limitations to that plan, the contributions are
                not includable in the gross income of the employee for the
                taxable year in which contributed.  In addition, Employer
                contributions made on behalf of an Employee to a simplified
                employee pension described in IRC Section 408(k) are not
                considered as compensation for the taxable year in which
                contributed to the extent such contributions are deductible by
                the Employee under IRC Section 219(b)(7).  Additionally, any
                distributions from a plan of deferred compensation are not
                considered as compensation for IRC Section 415 purposes,
                regardless of whether such amounts are includable in the gross
                income of the Employee when distributed.  However, any amounts
                received by an Employee pursuant to an unfunded non-qualified
                plan may be considered as compensation for IRC Section 415
                purposes in the year such amounts are includable in the gross
                income of the Employee.

          (ii)  Amounts realized from the exercise of a non-qualified stock
                option, or when restricted stock (or property) held by an
                Employee either becomes freely transferable or is not longer
                subject to a substantial risk of forfeiture (see IRC Section 83
                and the regulations thereunder).

          (iii) Amounts realized from the sale, exchange or other disposition
                of stock acquired under a qualified stock option.

          (iv)  Other amounts which receive special tax benefits, such as
                premiums for group term life insurance (but only to the extent
                that the premiums are not includable in the gross income of the
                Employee), or contributions made by an Employer (whether or not
                under a salary reduction agreement) towards the purchase of an
                annuity contract described in Section 403(b) (whether or not the
                contributions are excludable from the gross income of the
                Employee).

                     SECTION 14 - MISCELLANEOUS PROVISIONS


 14.01 SPENDTHRIFT CLAUSE.  Except as provided in Section 14.02, benefits or
       payments from this Plan shall be paid to the individual entitled to
       receive them personally and upon his personal receipt or endorsement.  No
       Participant, spouse or Beneficiary shall have the right or power to
       transfer, assign, anticipate, mortgage, pledge or otherwise encumber this
       interest in the Trust established by this Agreement, or his rights to
       receive payments or benefits from the Trust and neither such interests
       nor rights nor any assets of the Trust shall be subject to seizure or
       sequestration for the payment of any debts, judgments, alimony or
       separate maintenance owed by the Participant or Beneficiary nor to
       transferability by operation of law in the event of bankruptcy,
       insolvency or otherwise, provided, however, that this limitation shall
       not apply to a qualified domestic relations order under IRC Section
       414(p).

 14.02 FACILITY OF PAYMENT.  If any person to whom payments are to be made under
       the Plan is in the judgment of the Committee or an insurance company that
       has issued an annuity policy pursuant to Section 7.10 under a legal
       disability, or by reason of mental or physical disability is in the
       opinion of the Committee or such insurance company unable to administer
       properly such payments, even though such person has not been legally
       adjudicated incompetent, then such payment or payments may be made to any
       person, persons, or institution as, in the option of the Committee or the
       insurance company, is then maintaining or has custody of such person
       until claim is made by a duly appointed guardian or other legal
       representative of such person.   Such payment shall constitute a full
       discharge of liability of the Plan to the extent thereof.

 14.03 EVIDENCE OF SURVIVAL.  The Committee or an insurance company shall have
       the right to require satisfactory evidence that a person entitled to
       receive benefits hereunder is living on each and every date when a
       benefit is due such person.  In the absence of such evidence, when
       required, any payments otherwise due shall not be made until such
       evidence shall have been received.

 14.04 DISCRETIONARY ACTS TO BE UNIFORM.  Any discretionary acts to be taken
       under the Plan by the Committee, or any person or persons to whom
       authority has been delegated, shall be uniform in their nature and
       applicable to all persons similarly

                                                                   page 64 of 91
 
       situated, and no discretionary acts shall be taken that will be
       discriminatory under the applicable provisions of the IRC pertaining to
       qualified plans.

 14.05 ELECTIONS TO BE MADE ON PRESCRIBED FORMS.  All elections, claims,
       designations, and revocations made by Participants or other persons under
       the Plan shall be made in writing on forms prescribed by and furnished by
       the Committee and shall not be effective until filed with the Committee.

 14.06 RELIANCE ON INFORMATION FURNISHED BY EMPLOYER.  Any information furnished
       by the Employer to the Committee, such as compensation of Employees,
       length of service, Hours of Service, or otherwise, shall be accepted by
       the Committee as being true and correct, and the Committee shall incur no
       liability in relying on such information.

 14.07 INABILITY TO PERFORM.  Neither the Employers nor the Committee shall be
       responsible for any inability to perform, or delay in performing, any act
       occasioned by any restriction or provisions imposed by the Trustee, or by
       any other person, or by law, and in the event any such inability or delay
       shall be so occasioned, then that act which can be performed shall be
       performed by the Employers or the Committee which, in the sole discretion
       of the Committee, most completely carries out the intention and purpose
       of this Plan.  All parties of this Plan or in any way interested therein
       shall be bound by any acts so performed under such conditions.

 14.08 MISSTATEMENT OF AGE.  In the event an Employee misrepresents his age or
       his spouse's age to his Employer or the Committee, he shall be entitled
       to the lesser of the following benefits:

       (a) The benefit that would be payable on the basis of actual age; or

       (b) The benefit that would be payable on the basis of the misrepresented
           age.

 14.09 RIGHTS OF INDIVIDUALS.  No Employee, nor any person claiming by, through,
       or under such Employee, shall have any right, title, or interest in or to
       the Retirement Fund except such right to a benefit as expressly provided
       herein.  No Employee shall be entitled to receive any part of the
       contributions of the Employers or any other cash consideration upon his
       withdrawal from the services

                                                                   page 65 of 91
 
       of the Employers, or the termination of his services by the Employers,
       unless otherwise provided herein, or upon the discontinuance of the Plan
       except to the extent provided herein.  All rights and claims are limited
       as set forth hereunder and no Participant or other person shall have any
       recourse toward satisfaction or payment of any benefit provided by this
       Plan from other than the Retirement Fund or the Pension Benefit Guaranty
       Corporation.  Nothing contained herein gives, nor is intended to give,
       any Employee the right to be retained in the service of the Employers,
       nor to interfere with the right of the Employers to discharge or
       terminate the employment of an Employee at any time and this Plan shall
       in no event be construed as a contract of employment between any Employer
       and the Employee.

 14.10 ACTUARIAL COMPUTATIONS.  The Committee, Trustees and the Employer shall
       be entitled to conclusively rely upon any actuarial computations or
       evaluations made by an insurance company or an actuary or a firm of
       actuaries.  Except in case of a mathematical error, each Employee, or
       person claiming through any Employee, shall be conclusively bound by any
       actuarial computation or evaluation made by an insurance company or an
       actuary or a firm of actuaries, provided, however, the determination of
       an actuarial equivalent of another form of payment or the present value
       of future payments that may become payable shall be made on the basis of
       the following factors until such time as the applicable law or rulings of
       the Internal Revenue Service no longer requires fixed standards for
       actuarial assumptions used in determining actuarial equivalents to be set
       forth in the Plan:

       Table
       -----

          Unisex Pension Table - 1984 (UP-1984) with a two year age setback,
          except that the age setback shall be one year for a contingent
          annuitant under a joint and survivor annuity option.

       Interest
       --------

          Interest factor of seven and one-half percent (7.5%), except that
          single sum distributions shall be based upon an interest factor which
          shall be adjusted as of the first day of each calendar month to be the
          monthly annuity rate (immediate or deferred) of the Pension Benefit
          Guaranty Corporation for that calendar month.

                                                                   Exhibit 10(H)
                                                                   page 66 of 91
 
          The following rules shall apply to the interest factor:

          (i)   In figuring whether the single sum actuarial equivalent under
                Section 7.09 exceeds $3,500, the interest rate used shall not
                exceed the Pension Benefit Guaranty Corporation ("PBGC")
                interest rate or rates for purposes of determining the present
                value of a lump sum distribution on plan termination, as in
                effect on the first day of that calendar month.

          (ii)  In figuring whether such single sum actuarial equivalent exceeds
                $25,000, the interest rate shall not exceed 120% of the PBGC
                interest rate but such increase in the allowable PBGC rate may
                in no event cause the single sum actuarial equivalent to be less
                than $25,000.

          (iii) This Section shall apply to distributions in Plan Years
                beginning after December 31, 1986.  The Section shall also apply
                to distributions in Plan Years beginning after December 31,
                1984, which were not made in accordance with regulations issued
                under the Retirement Equity Act of 1984, other than
                distributions under an annuity contract distributed to or owned
                by a Participant prior to September 17, 1985, unless additional
                contributions were made by the Employer under such contracts.

 14.11 NOTICE OF REQUIRED ACTION.  In any case in which an Employer, the
       Committee, or the Trustee shall be directed to take any action upon the
       occurrence of any event, they, or any one or more of them, shall be under
       no obligation or liability to take such action unless and until notice,
       proper and satisfactory to them shall first have been received or the
       occurrence of such event.  For the purposes of this Section 14.11, a
       certificate in writing signed by an officer of the Company and delivered
       to the Committee or the Trustee, or a certificate in writing from the
       Committee to the Trustee as to the occurrence or happening of any event,
       shall constitute conclusive evidence of such occurrence or happening, and
       the Committee and the Trustee, respectively, shall be fully protected and
       discharged from all liability whatsoever in accepting and relying on such
       certificate.  No Trustee shall be required to go a back of any action of
       the Committee, and no Trustee shall be responsible to see that any action
       of the Committee is authorized by the terms of this agreement.

                                                                   page 67 of 91
 
 14.12 RELIANCE UPON COMMUNICATION.  Neither the Employers, the Committee,
       nor any agent of the Trustees shall incur any liability in acting upon 
       any notice, request, signed letter, telegram, or other paper or documents
       reasonably believed by any one of them to be genuine and to be signed or
       sent by the proper person.

 14.13 NO REVERSION TO EMPLOYERS.  The Employers shall in no event, either
       directly or indirectly, receive any fund or contributions made by it to
       the Trust, nor directly or indirectly participate in the distribution, or
       receive the benefits of the assets or funds comprising the Retirement
       Fund prior to the satisfaction of all liabilities with respect to
       Employees, beneficiaries, and spouses under this Plan; provided, however,
       if there are any assets remaining after all such liabilities have been
       satisfied they shall be returned to the Employers; provided, further:
       that (subject to the limitations of Revenue Ruling 91-4):

       (a) If a contribution is made by a mistake of fact, the mistaken portion
           of the contribution shall be returned within one year after payment
           of the mistaken contribution upon the Employer's written request; and

       (b) Each contribution by the Employer is conditioned upon the
           deductibility of the contribution under the applicable section of the
           IRC.  Accordingly, to the extent of disallowance of the deduction for
           the part or all of the contribution, the contribution shall be
           returned within one year after disallowance upon the Employer's
           written request.

       Upon transfer to the Trustees, all responsibilities of the Employers for
       each contribution shall cease, and the Employer shall have no
       responsibilities for the acts of the Trustees.

 14.14 INSURER NOT PARTY TO AGREEMENT.  No insurance company (other than the
       Employers) shall be deemed a party to this Plan for any purpose.

 14.15 CONSTRUCTION.  It is intended that this Plan and the Trust Agreement
       which is a part thereof shall comply with the provisions of ERISA and
       constitute a qualified plan and trust under the Provisions of Section
       401(a) of the IRC, and be operated in a manner so as not to discriminate
       in favor of Highly Compensated Employees as defined at Section 414(q) of
       the IRC.  Accordingly, the provisions of this Plan and the Trust
       Agreement shall be construed and applied in a manner consistent

                                                                   Exhibit 10(H)

       with such intent.  However, to the extent not superseded by ERISA, this
       Plan and the Trust Agreement which is a part thereof, shall be construed
       and enforced in accordance with the laws of the State of Illinois.

 14.16 SECTION TITLES NOT PART OF AGREEMENT.  The section designations and
       titles are included solely for convenience and shall, in no event, be
       construed to affect or modify any of the provisions of this Agreement or
       be construed as a part thereof.

 14.17 GENDER AND CASE.  Where used in this Agreement, words in the masculine
       shall be read and construed as in the feminine, and words in the singular
       shall be read and construed as though used in the plural, in all cases
       where such constructions would so apply.  Unless the context requires
       otherwise, such words as "herein" "hereto" "hereinafter" "hereinbefore"
       or "hereunder" refer to this instrument as a whole and not merely to the
       subdivisions in which such words appear.

 14.18 ELIGIBLE ROLLOVER DISTRIBUTIONS.  Effective with respect to distributions
       made on or after January 1, 1993, a distributee may elect, at the time
       and in the manner prescribed by the plan administrator, to have any
       portion of an Eligible Rollover Distribution paid directly to an Eligible
       Retirement Plan specified by the distributee in a Direct Rollover.  For
       purposes of this Section 14.18:

       (a) An "Eligible Rollover Distribution" is any distribution of all or any
           portion of the balance to the credit of the distributee, except that
           an Eligible Rollover Distribution does not include:  any distribution
           that is one of a series of substantially equal periodic payments (not
           less frequently than annually) made for the life (or life expectancy)
           of the distributee and the distributee's designated beneficiary, or
           for a specified period of ten years or more; any distribution to the
           extent such distribution is required under Section 401(a)(9) of the
           Code; and the portion of any distribution that is not includable in
           gross income (determined without regard to the exclusion for net
           unrealized appreciation with respect to employer securities).

       (b) An "Eligible Retirement Plan" is an individual retirement account
           described in Section 408(a) of the Code, an individual retirement
           annuity described in Section 408(b) of the Code, an annuity plan
           described in Section 403(a) of the Code, or a qualified trust
           described in Section 401(a) of the Code, that accepts the
           distributee's Eligible Rollover Distribution.  In the case of an

           Eligible Rollover Distribution to the surviving spouse, an Eligible
           Retirement Plan is an individual retirement account or individual
           retirement annuity.

       (c) A "Distributee" is an employee or former employee, the employee's or
           former employee's surviving spouse and the employee's or former
           employee's spouse or former spouse who is the alternate payee under a
           qualified domestic relations order, as defined in Section 414(p) of
           the Code.

       (d) A "Direct Rollover" is a payment by the Plan to the Eligible
           Retirement Plan specified by the Distributee.

 15.01 ADOPTION OF PLAN.  This Plan has been adopted by Combined Insurance
       Company of America, Combined American Insurance Company, Combined
       Insurance Company of Wisconsin, and Combined Life Insurance Company of
       New York.  Any other Subsidiary of the Company, by proper resolutions
       adopted by its Board, or by an adoption agreement executed by a principal
       executive officer, may become a party to this instrument by adopting this
       Plan as its pension plan for its Staff Employees.  A certified copy of
       such resolutions shall be delivered to the Trustees.

 15.02 INTENTION OF PARTIES.  The provisions of this Plan shall be construed as
       the pension plan of each of the Employers that may adopt this Plan as its
       pension plan and each such Employer shall contribute the cost
       attributable to its Employees, as may be determined by the Company.
       Except as otherwise may be provided herein, or as may be provided in the
       resolutions of an adopting Subsidiary, it is the intention of the parties
       hereto that the Employees of the Company and the Employees of any
       Subsidiary that adopts this Plan or has adopted this Plan shall receive
       the same benefits as they would receive if all the Employers were one
       corporate entity and this Plan were the plan of such entity, and the
       provisions of this Plan shall be interpreted in accordance with this
       intent.

 15.03 TERMINATION BY ONE EMPLOYER.  In the event any Employer discontinues the
       Plan in accordance with the provisions of Section 10, this Plan shall
       only be discontinued in respect to such Employer and its Employees but
       not in respect to the other Employers that have adopted the Plan; it
       being understood that the Plan shall continue in full force and effect as
       to any such other Employers and their Employees.

 16.01 RIGHTS OF FORMER EMPLOYEES.

       The rights of Employees whose employment terminated prior to January 1,
       1989, shall be determined by the terms of the Plan as they existed prior
       to January 1, 1989; provided, however, that if any such individual again
       becomes an Employee his rights shall be determined by the terms of the
       Plan at the time he again becomes an Employee and such amendments thereto
       as may thereafter be adopted.

          SECTION 17 - PROVISIONS APPLICABLE IF PLAN BECOMES TOP-HEAVY


 17.01 APPLICABILITY.  The provisions of this Section 17 shall be applicable
       during any Plan Year commencing subsequent to December 31, 1983, but only
       if the Plan was a Top-Heavy Plan or was part of a Top-Heavy Group on the
       Determination Date, and in such case shall override and supersede all
       other provisions in this Plan to the contrary; provided, that these
       provisions shall not apply to a Plan which is not itself a Top-Heavy Plan
       and which was included in an Aggregation Group under the second sentence
       of Section 17.02(f); provided further, that, these the extent permitted
       by law, Section 17.05 shall not apply to any Employee who has received

                                                                   page 76 of 91
 
           Employee and made after December 31, 1983, to a plan shall not be
           taken into account with respect to the transferee plan.

       (b) If any individual is a Non-Key Employee with respect to the Plan for
           any Plan Year, but such individual was a Key Employee with respect to
           the Plan for any prior Plan Year, any accrued benefit for such
           Employee (and the account of such Employee) shall not be taken into
           account for purposes of Sections 17.02(e), (f) and (g).

       (c) To the extent provided in regulations issued by the Secretary of
           Treasury, the Top-Heavy rules of this Section shall be applied on the

           Years.

       (d) In determining present values and account balances under Section
           17.02(e), (f), and (g), all distributions made with respect to any
           Employee during the 5-year period ending on the Determination Date
           shall be added back and included therein.  The preceding sentence
           shall also apply to distributions under a terminated plan which if it
           had not been terminated would have been required to be included in an
           Aggregation Group.

       (e) In determining the present value of accrued benefits under Section
           17.02(e) or (g), amounts attributable to deductible employee

           benefits.

           for any Employer maintaining the Plan at any time during the 5-Year
           period ending on the Determination Date, any accrued benefit for such
           Employee (and the account of such individual) shall not be taken into
           account.

 17.04 VESTING WITH RESPECT TO PARTICIPANT'S TOP-HEAVY BENEFIT.  In lieu of the
       vesting schedule set forth in Section 5.02, a Participant, provided he
       earns at least one Hour of Service after the Plan becomes Top-Heavy,
       shall vest in his Top-Heavy Benefit according to the following schedule:

           Completed Years of Service            Non-Forfeitable %
                       2                                20%
                       3                                40%

                                                                   page 77 of 91
 
                       4                                60%
                       5                                80%
                       6                               100%

 17.05 MINIMUM BENEFIT FOR NON-KEY EMPLOYEE.  The Normal Retirement Benefit
       derived from Employer contributions for each Participant in a Top-Heavy
       Plan, when expressed as an Annual Retirement Benefit, shall not be less
       than the Applicable Percentage of his average Compensation in the Testing
       Period.  The Participant's accrued benefit under Section 2.01 shall not
       be less than the amount of such Top-Heavy Benefit.  Any accrued benefits
       derived from Employer contributions, whether or not attributable to years
       for which the Plan is a Top-Heavy Plan, may be used to satisfy such
       minimum benefit.

 17.06 MAXIMUM ANNUAL BENEFIT.  The limitations of Section 13.05 shall be
       applied by substituting 1.0 for 1.25 where it appears in Section 13.05(g)
       in the denominators of the defined benefit plan fraction and the defined
       contribution plan fraction.  However, if the plan would not be a Top-
       Heavy Plan or part of a Top-Heavy Group if 90% were substituted for 60%
       in Sections 17.02(e) and (g), then "3 percent" shall be substituted for
       "2 percent" as the minimum benefit for any defined contribution plan in
       the Top-Heavy Group and the preceding sentence shall not apply.  The
       application of the first sentence of this Section 17.06 shall be
       suspended with respect to any Participant so long as there are no (i)
       Employer contributions, forfeitures or voluntary nondeductible
       contributions allocated to such Participant or (ii) accruals for such
       Participant under any defined benefit plan.  If the first sentence of
       this Section 17.06 is applicable, Section 13.05(h) shall be applied by
       substituting $41,500 for $51,875.

 17.07 SIMPLIFIED EMPLOYEE PENSIONS.  For purposes of Section 17, a Simplified
       Employee Pension shall be treated as a defined contribution plan.  At the
       Employer's election, the aggregate Employer contributions to a Simplified
       Employee Pension may be taken into account in lieu of the aggregate of
       the accounts of the Employees for the purpose of determining whether the
       Plan is part of a Top-Heavy Group pursuant to Section 17.02(g).

 17.08 CONTRIBUTIONS OR BENEFITS NOT TAKEN INTO ACCOUNT.  The Plan must meet the
       requirements of Sections 17.05 and 17.06 without taking into account (i)
       contributions or benefits under Chapter 2 of the IRC (relating to tax on
       self-

       insurance Contributions Act; (iii) Title 11 of the Social Security Act;
       or (iv) any other Federal or State law.

 17.09 EMPLOYMENT IN BARGAINING UNIT.  The provisions of Sections 17.02(j),
       17.04 and 17.05 shall not apply with respect to any Employee employed in
       a bargaining unit described in Section 3.02(d).

 17.10 COMMENCEMENT OF BENEFITS.  Notwithstanding Section 7.11(a), distributions
       to a Key Employee shall commence not later than the end of his taxable
       year in which he attains age 70-1/2 whether or not he has retired.

 17.11 FORFEITURES. No portion of a Participant's Top-Heavy Benefit maybe
       forfeited under Section 7.11 or because of his withdrawal of any amount
       attributable to the benefit derived from mandatory contributions made by
       such Participant.

                  SECTION 18 - MERGERS AND TRANSITIONAL RULES


 18.01 GENERAL.  As part of the 1989 Restatement of The Plan, both the
       Retirement Plan for Employees of the Life Insurance Company of Virginia
       and Designated Subsidiaries and Designated Affiliates ("LOV Pension
       Plan") and the Miller, Mason & Dickenson, Inc.  Pension Plan ("MMD
       Pension Plan") were merged into this Plan as set forth below.  It is the
       intention of this Section to set forth the transitional rules applicable
       to former participants in those plans, and also to set forth transitional
       rules for former participants in the Rollins Burdick Hunter Co. Employees
       Pension Plan which was merged into this Plan effective January 1, 1986;
       and for former participants in the Pension Plan for the Employees of
       Booke and Company ("Booke Plan") which was merged into this Plan
       effective August 1, 1993.

 18.02 MERGERS AND TRANSFERS OF ASSETS AND LIABILITIES.  Effective as of January
       1, 1989, or as soon as administratively convenient thereafter, the
       following mergers and transfers of assets and liabilities took place.

       (a) Participants under the LOV Pension Plan became Participants in this
           Plan as of January 1, 1989. The Trustee shall deposit and hold as
           part of the Retirement Fund the transferred assets, as certified to
           by the Trustee under the LOV Pension Plan as provided for by the
           Amendment to such plan pursuant to which the assets of such plan are
           turned over and delivered to the Trustee of this Plan.

       (b) Participants under the MMD Pension Plan shall became Participants in
           this Plan as of January 1, 1989. The Trustee shall deposit and hold
           as part of the Retirement Fund the transferred assets, as certified
           to by the Trustee under the MMD Pension Plan as provided for by the
           Amendment to such plan pursuant to which the assets of such plan are
           turned over and delivered to the Trustee of this Plan.

 18.03 THE RETIREMENT PLAN FOR EMPLOYEES OF THE LIFE INSURANCE COMPANY OF
       VIRGINIA AND DESIGNATED SUBSIDIARIES.  In figuring  the normal retirement
       benefit under Section 4.01, the 25 years of Service maximum under Section
       4.01(b) shall take into account years of credited service for a former
       Participant in the LOV

                                                                   page 80 of 91
 
       Pension Plan prior to such date and such years of credited service shall
       reduce the remaining years available as of January 1, 1989.  The post-
       retirement cost of living adjustment ("COLA") under the LOV Pension Plan
       at former Section IX is eliminated but the accrued benefit of a
       Participant as of December 31, 1988, shall be calculated so as to take
       into account an actuarial increase to reflect the COLA as of such date
       but only for Participants who attain age 55 with 10 or more years of
       credited service.  A Participant's pre-retirement death benefit under the
       66-2/3% joint and survivor annuity form as of December 31, 1988, shall be
       the minimum amount of such benefit.  As required under Reg.  Section
       1.410(a)-7(f) upon transfer from an elapsed time plan to a plan using the
       general method, as of January 1, 1989, former participants shall get
       credit for the same number of Years under this Plan as were credited
       under the LOV Pension Plan; provided, however, that future benefits shall
       be reduced to take into account any part year credited under the LOV
       Pension Plan; provided further, however, that the actual Hours of Service
       for the full Plan Year beginning January 1, 1989, shall be used since the
       computation period which includes the date of transfer is a full year and
       not a fractional year.  Since the accrual rate of benefits is reduced,
       the amendment to the early termination rule at Section 11 shall not
       apply.  The career average formula for Ordinary Field Representatives (as
       defined in the LOV Pension Plan) is preserved through December 31, 1988,
       and the normal retirement benefit under Section 4.01 shall apply for
       service on or after January 1, 1989; provided, however, that service of
       an Ordinary Field Representative prior to January 1, 1989 shall be taken
       into account in figuring years available under Section 4.01(b) and Final
       Average Earnings.  The formula for such field representatives shall be 1%
       of pay up to $17,000 plus 1.5% of pay in excess of $17,000.  Accrued
       benefits as of December 31, 1988 shall be calculated as set forth at
       Section 5.03(c).

 18.04 MILLER, MASON & DICKENSON, INC. PENSION PLAN.  With respect to the
       maximum credit under Section 4.01(b) of 25 Years of Service on or after
       January 1, 1989, prior years of credited service under the MMD Pension
       Plan shall be taken into account and reduce the 25 years maximum in the
       same manner as provided under Section 18.03 for the LOV Pension Plan.
       The offset to the retirement benefit for account balances in the former
       Miller, Mason & Dickenson, Inc. Money Purchase Pension Plan is preserved.
       Any Participant with four years of vesting service as of December 31,
       1988 shall be given 40% vesting as of January 1, 1989.  Accrued

Rollins Hudig Hall     As the the retail brokerage and risk management arm of
                       Aon, Rollins Hudig Hall (RHH) is the largest contributor
                       to the revenues of the commercial operations. Despite
                       severe pressure on pricing throughout the brokerage
                       industry, particularly in the U.S. market, RHH recorded
                       worldwide revenues of $701.4 million in 1994, up 5.8
                       percent from $663 million in 1993. Domestic revenues were
                       70 percent of total worldwide revenues, with
                       international accounting for the balance.

                       1994 Revenue              Through acquisition and 
                       as a percent of total   internal growth, RHH has  
                       Commercial Operations   assembled some of the best talent
                                               in the industry in an extensive
                                               variety of niches, and created an
                                               organization that can bring this
                                               talent to the service of clients
                                               throughout the world.

                                                 Areas that saw important
                       ---------------------   expansion in 1994 include
                                               construction, transportation,
                       energy, financial services, entertainment and health
                       care. In addition, in 1994, RHH enhanced its position as
                       a specialist in satellite risks, forming Space Risk
                       International in conjunction with Nicholson Leslie.
                       Further, the 1994 acquisition of Houston energy broker
                       Energy Insurance International (EII), combined with our
                       existing expertise, positions RHH as a leader serving the
                       vital and growing energy industry.

                         RHH emphasizes interdependence, bringing its vast
                       resources together to find the best solutions for each
                       client, going beyond the traditional role of the broker.
                       The professionals of RHH work in partnership with
                       clients, developing and delivering innovative solutions
                       for each insurance need.

                         As part of this commitment to provide the highest
                       levels of service, RHH in 1994 established the Knowledge
                       Network, a global communication system that enables RHH
                       professionals to share market intelligence, identify
                       specific expertise, and facilitate improved communication
                       with each other and with clients. RHH also has actively
                       responded to clients seeking to outsource portions of
                       their risk management activities.

                         RHH's operations in Europe and elsewhere overseas are
                       working with RHH in the United States, using specialty
                       practice groups to pursue business in specific
                       industries, to share information and to develop
                       innovative products and services.

                         RHH commercial insurance brokerage operates through its
                       offices in the United States and Europe, as well as in
                       the Far East, Latin America and the Middle East. RHH is
                       actively pursuing expansion in Latin America and the Far
                       East. During 1994, RHH opened offices in Russia, Finland,
                       Turkey, Portugal and Slovakia, and expanded its rapidly
                       growing European art brokerage business, operating under
                       the name ArtScope, with acquisitions of specialized art
                       brokers in France and Germany. Together with its
                       Huntington T. Block operation in Washington, RHH is now
                       one of the leading art brokerage specialists in the
                       world.

                         RHH also acquired an Australian broker specializing in
                       group programs, making RHH one of the largest such
                       brokers in that part of the world. Building on the
                       success of Aon's affinity group program business in the
                       United States and in Europe, RHH is expanding a worldwide
                       group program business.

                         RHH continues to build its pool of talented
                       professionals, to add to its distribution capabilities
                       and to expand its expertise. The breadth of its
                       resources, as well as the ability to bring these vast
                       resources to bear in a very direct way in the service of
                       each client, differentiates RHH in the global brokerage
                       arena.

                         ASG formed the Aon Alliance in 1993 to meet the unique

                       River Learning Centers Inc. extends that expertise into a
                       broad range of industries, including some of the largest
                       multinational corporations. Further, it builds upon a

Aon Risk Services                              A key to Aon's growth in 1994 was
                                               the growing significance of the
                                               expertise provided by Aon Risk
                                               Services (ARS) to insurance
                                               organizations. The alternative
                                               insurance market, both
                                               conventional and non-
                                               conventional, continues to
                                               experience explosive growth, as
                                               large multinational companies
                                               look for more control over the
                                               cost and configuration of their
                                               risk-protection strategies.
                                               Working with other RHH Group
                                               operations, ARS has emerged as
                                               one of the premier players in
                                               this increasingly important
                                               arena.

                       1994 Revenue              ARS experienced an outstanding
                       as a percent of total   year in 1994, with growth in
                       Commercial Operations   virtually every line of business.
                                               Revenues increased 33.5 percent
                                               in 1994, to $258.5 million from
                                               $193.6 million in 1993.

                       ---------------------     Aon Re Worldwide, formed in
                                               1993 to bring together all the
                                               reinsurance operations of ARS,
                       has become one of the top reinsurance intermediaries in
                       the world. Included in ARS revenues are reinsurance
                       brokerage revenues that increased 40.3 percent in 1994,
                       to $103.4 million from $73.7 million a year earlier. The
                       increase in revenues was fueled largely by the formation
                       of strategic alliances with other insurers.

                         The captive management and alternative market services
                       in Europe were combined under the name Aon Risk Services
                       (Europe). In 1994, we opened new offices in Luxembourg
                       and The Netherlands. Agricultural Risk Management in
                       London, specializing in the evaluation of agricultural
                       risk, was acquired in early 1995. Through Aon Risk
                       Consultants, ARS offers actuarial expertise, catastrophe
                       modeling and alternative risk financing products to the
                       global marketplace. SLE Worldwide, a managing general
                       underwriter in the sports, leisure and entertainment
                       industries, recorded significant revenue increases.

                         In the United States, ARS established Aon Risk
                       Technologies, which conducts research and development in
                       risk-evaluation systems, and opened a Los Angeles office
                       for Aon Broker Services. Wexford Underwriting Managers,
                       which specializes in the alternative market for workers
                       compensation, experienced significant growth in 1994.

                         At year-end, Sherwood Insurance Services, a wholesale
                       brokerage unit of ARS, announced a cooperative venture
                       with CNA Insurance Companies to enter the commercial
                       property insurance market. This venture is targeting
                       major companies, here and abroad.

                         The growth of ARS over the last several years should
                       continue in concert with the growth of the alternative
                       market. Leaving the traditional insurance market can
                       offer large companies significant advantages, but it also
                       requires great sophistication, creativity and an
                       understanding of the market. ARS, with its experience and
                       resources, is a valuable and important resource for RHH
                       offices in meeting the needs of major companies seeking
                       to navigate the alternative market.

Insurance                                      America (CICA) has built a long
Company                                        tradition of providing consumers

                                               $272.8 million, or 27.9 percent
                                               of the total; this was an
                                               increase of 7.2 percent over
                                               $254.4 million in 1993.

                       domestic life business recorded its most successful year
                       in the last 10 years with $111.8 million in revenues.

                         Accident and health (A&H) business also grew in 1994,
                       with revenues of $845.9 million, up 4.5 percent from

                       Domestically, new sales of A&H products increased in the
                       fourth quarter, with health sales showing a double-digit
                       rate of growth for the year.

                       began in 1993, continued to develop. In addition, CICA

                       licensed in Mexico during 1994. CICA will begin test-
                       marketing in Mexico in 1995.

                                               business, which is marketed
                                               primarily through third-party and
                                               affinity groups, posted strong
                                               results in 1994. For the first
                                               time in its history, the company
                                               issued more than 1 million new
                                               policies.
                       1994 Revenue
                       as a percent of total     This growth was fueled by some
                       Consumer Operations     significant new business,
                                               including the acquisition of a
                       ---------------------   major Medicare Supplement
                                               portfolio, and new relationships
                                               with major sponsoring            
                                               organizations. These
                                               relationships were developed with
                                               the help of other Aon companies,
                                               exemplifying the spirit of
                       interdependence among Aon units.

                         A major area of growth for Combined Group was voluntary
                       insurance coverages, particularly dental and disability
                       plans. Employers offer these coverages to employees at
                       group rates; employees who choose to participate pay
                       their cost through payroll deduction. This product line
                       is expected to expand, as the cost of traditional
                       employer-provided benefits rises, especially for smaller
                       employers.

                         Life insurance revenues for UFLIC and Combined Group
                       direct-response business totaled $57.7 million in 1994,
                       up 8.7 percent from $53.1 million in 1993. Revenues from
                       accident and health business were $314.1 million in 1994,
                       up 23 percent from $255.3 million a year earlier.

                         In addition, revenues attributable to financial
                       institution mortgage and credit insurance underwritten by
                       UFLIC reflected the elimination of low-margin business.
                       UFLIC sees opportunities for expanding relationships with
                       bank clients for additional insurance products that could
                       be distributed to their customers.

                                               The product portfolio includes

                                                 During 1994, LOV added a
                                               survivorship universal life
                                               coverage, which pays on the death
                                               of the second of a joint life
                                               insured. Additionally, its term
                                               life and universal life products
                       1994 Revenue            were revised to meet the rapidly
                       as a percent of total   changing needs of the
                       Consumer Operations     marketplace.

                                                 Last year, interest rate
                       ---------------------   spreads narrowed on capital
                                               accumulation products. In 1994,
                       LOV earned a 136 basis-point interest rate spread
                       compared to 170 basis points in 1993. The interest rate
                       spread narrowed primarily due to reinvestment at lower
                       yields of proceeds from bonds called and mortgage-backed
                       securities prepaid, as well as sharply higher short-term
                       interest rates negatively affecting crediting rates on
                       indexed GICs.

                         Total life revenues were $634.4 million in 1994
                       compared to $625.7 million in 1993; capital accumulation
                       products accounted for $529.9 million, up 1 percent from
                       1993. Traditional life revenues increased to $104.5
                       million in 1994.

                         Life revenues reflect the fees earned on variable
                       product sales. Variable product sales continued to be
                       strong. Variable annuity sales rose 97 percent. Variable
                       life deposits increased 82 percent, and variable
                       universal life annualized premium sales were up 37
                       percent.

                                               casualty insurance. However, the
                                               growth in extended warranty
                                               business has largely compensated
                                               for the loss in revenues. Total
                                               worldwide revenues were $315.6
                                               million in 1994, compared with
                                               $326.2 million in 1993,
                                               reflecting this run-off. Extended
                                               warranty worldwide revenues were
                       1994 Revenue            up 22.8 percent in 1994, to
                       as a percent of total   $234.9 million from $191.3
                       Consumer Operations     million in 1993. Written premium
                                               rose substantially in 1994.

                                                 During 1994, Aon Warranty Group
                       ---------------------   was created to handle certain
                                               extended warranty products on
                       automobiles, electronic goods, personal computers and
                       appliances. In addition, the company acquired Independent

                                               expected to generate returns in
                                               excess of those available in the
                       ---------------------   public capital markets.

                                                 Aon maintains well-capitalized
                       operating companies. The financial strength of these
                       companies permits an overall diversified investment
                       portfolio for stability in volatile financial markets.
                       Moreover, the quality of invested assets remains solid,
                       as 97 percent of our rated bonds were investment-grade at
                       year-end.

                         Last year, interest rates moved sharply higher in most
                       countries where Aon operates. In the United States, bond
                       prices suffered their steepest loss in nearly 70 years.
                       This sharp increase in interest rates reduced the market
                       to book value of Aon's fixed maturity portfolio to 94.6
                       percent at year-end 1994 compared to 105.1 percent at
                       year-end 1993.

                         Investment income earned in 1994 totaled $759.5
                       million, modestly higher than the $745.2 million earned a
                       year ago. Lower yields on securities underlying capital
                       accumulation products were partially offset by higher
                       yields on insurance brokerage and consulting short-term
                       investments. The yield on average invested assets was
                       7.56 percent in 1994 compared to 7.55 percent a year
                       earlier.

                         Net investment income from insurance brokerage and
                       consulting activities totaled $46.6 million in 1994
                       compared to $37.5 million a year earlier. The 24.3
                       percent increase was due primarily to sharply higher
                       short-term yields in the United States and the United
                       Kingdom.

                         Through Aon Advisors, Aon manages funds and provides
                       consulting services on behalf of clients in addition to
                       our operating units. This includes acting as investment
                       advisor to mutual funds which are among the investment
                       options available to purchasers of LOV annuities. At 
                       year-end, nearly $1 billion of outside funds were managed
                       by Aon Advisors. This developing business line fits in a
                       seamless fashion with other Aon insurance consulting
                       activities.

                       Financing Operations
================================================================================

                       The specialized finance subsidiaries of Aon offer
                       financing services to commercial clients of RHH and other
                       independent organizations for their liability and
                       casualty premiums through Cananwill Inc., and offer auto
                       financing for individuals in partnership with select
                       retail auto dealerships through Aon Auto Capital
                       Corporation. Both these organizations enjoyed good growth
                       in 1994. Total revenues rose to $20.2 million, a 16.8
                       percent increase over 1993.

Aon Corporation  |  Management's Analysis of Operating  
                 |  Results and Financial Condition
 
Revenue and Income Before Income Tax
Consolidated Results for 1994 Compared to 1993

Total revenues amounted to $4.2 billion, an increase of 8.1%. This increase
was primarily due to the growth in brokerage commissions and fees resulting
from business combination activity and internal growth. Brokerage commissions
and fees increased 16.7% to $1.4 billion.

  Premiums and policy fees of $1.9 billion increased 6.1% in 1994 reflecting
improvement in the life and accident and health major lines of business. Life
premium and policy fees of $454.4 million increased 5.2%, primarily reflecting
policy fees on domestic capital accumulation products. Accident and health
premiums earned of $1.2 billion, an increase of 8.8%, were influenced by the
continued growth in Combined Insurance Company of America's (CICA) direct sales
business in addition to the direct response acquisition of a medicare
supplement block of business and growth in the third party line of business.
Specialty property and casualty premiums earned decreased 4.2% or $10.9 million
as anticipated, reflecting the phase-out of certain specialty liability
programs. A higher volume of new business in the extended warranty line
partially offset this decrease.

  Net investment income of $759.5 million increased 1.9% for the year. Pretax
investment portfolio yield of 7.56% was flat for the year when compared to
1993. Investment income was stable as reduced returns on securities underlying
capital accumulation products were partially offset by higher yields on
insurance brokerage and consulting short-term investments and investment in new
assets at higher yields.

  Net realized investment gains of $5.8 million decreased significantly,
largely reflecting the reduction in bond calls by issuers in 1994. Revenues
excluding realized investment gains increased 8.7% or $332.9 million when
compared to 1993.

  Benefits to policyholders increased 3%. Accident and health benefits
increased primarily due to the acquired direct response block of business
mentioned above. Additionally, the reduction in benefits on specialty liability
products primarily reflected the discontinuation of certain specialty programs.
Commissions and general expenses (excluding interest expense) increased 11.3%
for the year. Amortization of intangibles, which include deferred policy
acquisition costs, increased $19.3 million or 5.5%. Total benefits and expenses
increased 7.5% or $253.6 million over 1993. Pretax income increased $58.5
million or 12.2% due largely to growth in the brokerage businesses and to the
continued favorable phase-out of certain specialty property and casualty
underwriting programs.

  Fourth quarter revenue increased 10.5% to $1.1 billion reflecting business
combination activity and internal growth. Benefits and expenses of $952 million
increased 10.4% for the quarter. Pretax income increased $13.5 million or 11.7%.

Revenue and Income Before Income Tax
Consolidated Results for 1993 Compared to 1992

Total revenues amounted to $3.8 billion, an increase of 15.2%. Premiums and
policy fees were $1.8 billion, slightly below 1992. As anticipated, special
property and casualty premiums earned decreased reflecting reduced underwriting
of certain specialty liability programs. Net investment income of $745.2
million increased 1.1% for the year. Brokerage commissions and fees increased
68.2% to $1.2 billion. This increase was primarily due to the growth in
brokerage commissions and fees resulting from the late 1992 acquisition of the
businesses of Frank B. Hall & Co., Inc.

  During 1992, Aon adopted Statement of Financial Accounting Standards
(Statement) No. 106, "Employers' Accounting for Postretirement Benefits Other
Than Pensions," and Statement No. 109, "Accounting for Income Taxes." The 1992
results reflect a $79.6 million charge for the cumulative effect of these
changes in accounting principles. In addition, in 1992, Aon had pretax special
charges amounting to $86.5 million relating primarily to the consolidation of
global brokerage operations. For purposes of the following expense ratio
comparisons, these items have been excluded.

  Benefits to policyholders decreased 2.9% when compared to 1992. This
reduction primarily reflects the discontinuation of certain specialty property
and casualty programs. Total benefits and expenses increased 13.7% over 1992.
Commissions and general expenses (excluding interest expense) increased 24.2%
for the year primarily reflecting brokerage acquisition activity. Pretax income
excluding the 1992 special charges increased by 27.1% or $102.1 million.

Major Lines of Business

Highlights of operating performance were discussed earlier in this Annual
Report. Please refer to pages 14 through 25 for descriptions of Aon's
businesses and comments on each operation's revenue comparisons.

Insurance Brokerage and Consulting Services

Total revenue, which includes investment income, was $1,422.1 million in
1994, up 17%. The increase is due primarily to the contribution of acquisition
activity and internal growth. Domestic revenue of $1,033 million was up 20.8%
while international revenue increased 8.1%. Consulting related fees previously
included in Retail brokerage in 1993 have been reclassified to Consulting to
conform to the 1994 presentation.

  Pretax income was $158.8 million in 1994, up 24% from $128.1 million in 1993.
Domestic income was up 41.9% from 1993 while international income declined 6.5%,
primarily due to start-up activity. Retail brokerage benefited from integration
efficiencies and growth from acquisition activity; however, results continued to
be influenced by a highly competitive property and casualty pricing environment
and investment in new industry areas. 

                                       27
<PAGE>
 
Reinsurance and wholesale income improved due to the inclusion of the Jenner
Fenton Slade Group Limited (JFS) business combination, international expansion
of alternative market services and internal growth. In the Consulting line,
growth of specialized employee development programs marketed primarily through
the 1994 merger with Pecos River Learning Centers Inc. partially offset a
decline in income due to investments in new automobile training operations.

Life Insurance

Revenue was $946.9 million in 1994 up 1.3% from $935.1 million in 1993.
Domestic revenue of $886.9 million was up 0.8% while international revenue rose
8.1%. Capital accumulation products were negatively influenced by rising
interest rates and higher adjusted crediting rates causing investment spreads
to narrow. Sales of variable products increased when compared to prior year. In
addition, traditional life business in Europe and the Pacific is continuing to
run off as planned.

  Pretax income was $113.2 million in 1994, up 6.4% from $106.4 million last
year. Domestic income was up 10.7%. International income declined $3.6 million
or 38.3%, largely due to higher operating costs. Improved market conditions,
increased productivity, and better underwriting controls contributed to a
positive impact on auto credit business income during the year. On the majority
of life and variable annuity policies, lapse rates did not increase in 1994
from prior years. While lapse rates on fixed annuity policies that reached the
end of their surrender period did increase in 1994, these policies remain
profitable. Variations in mortality experience between years do not suggest any
fundamental changes and do not signal a trend.

Accident and Health Insurance

Revenue was $1,296.6 million in 1994, up 8% from $1,200.7 million in 1993.
Domestic revenue of $1,009.3 million was up 7.7% while international revenue
rose 9.2%. Domestically, the impact of the acquisition of the medicare
supplement block of business on direct response revenues and, to a lesser
extent, new business growth on direct sales products, were chiefly responsible
for this improvement. Financial credit disability revenue declined due to the
discontinuation of lower margin business. Auto credit insurance revenues
improved due to growth in new business.

  Pretax income was $177.7 million in 1994, up 6.5% from $166.8 million in
1993. Domestic and international income were up 5.8% and 8.2%, respectively.
Levels of persistency have been stable for this line of business.

  Both domestic and international direct sales income improved with continued
good expense control and strong health product sales. Expense savings and
growth in third party endorsed business primarily contributed to improved
income in direct response. Good expense controls and improved underwriting
ratios led to an improvement in auto credit income.

Specialty Property and Casualty Insurance

Revenue was $315.6 million in 1994, down 3.2% from $326.2 million in 1993.
Domestic revenue was down 6.6% while international revenue was up 15.8%.
Domestically, the continued phase-out of certain specialty property and
casualty underwriting programs offset good warranty revenue growth.
Internationally, revenue improvements reflect growth in the extended warranty
mechanical repair and brown and white lines.

  Pretax income was $53.5 million in 1994, up 23% from $43.5 million in 1993.
Domestic income was up 21%. International income was up sharply due to improved
claims experience and a higher volume of new business in the extended warranty
line. Specialty liability programs continued to be phased-out with favorable
income results.

Corporate and Other

Revenue consists primarily of investment income on capital, premium finance
revenue, and realized investment gains before tax. Expenses include interest
and financing expenses, corporate administrative expenses, and goodwill
amortization associated with acquisitions. Revenue increased 4.7% over 1993 to
$175.7 million. Realized investment gains were $20.8 million lower in 1994 than
1993. The 1993 realized investment gains reflected a high number of corporate
bond calls by issuers. Excluding these gains from both years, the revenue
increase of 20.3% reflects growth in financing fees and new investments in
higher yielding securities. Allocation of investment income to the operating
segments is determined by each segment's investable assets as well as the
related yield on these investments. The remaining investment income is reported
in this segment.

  Pretax income of $34.4 million in 1994 increased modestly over 1993.
Excluding realized investment gains from both years, pretax income increased
$20.9 million or over 200%. The increase primarily reflects improved investment
yields and investment mix, as well as, a reduction in the level of internal
funds employed for acquisition financing. The premium financing business
experienced continued growth. In addition, financing costs and goodwill
amortization related to acquisitions grew more slowly when compared to the
growth in investment income.

Geographic Segments

The international segment is primarily composed of insurance brokerage and
consulting services, accident, health and life products of CICA, and The Ryan
Group credit insurance and extended warranty products. Overall, international
results were influenced by favorable foreign exchange rates in 1994.
International revenues increased 9.2% to $833.3 million primarily reflecting
the improvement in brokerage revenues relating to internal growth and
acquisitions. International pretax income increased slightly when compared to
1993 to $118.2 million.

  Domestic revenues increased 7.8% primarily reflecting brokerage acquisition
activity. Pretax income increased 16.1% primarily on the strength of
acquisition activity, improved benefit experience in life insurance and
specialty property and casualty business lines, and overall expense controls.

Income Tax and Net Income

On March 18, 1994, the Board of Directors authorized a three-for-two stock
split, payable in the form of a stock dividend, of Aon's $1.00 par value common
stock. All references to share data in the accompanying management's discussion
and analysis and financial statements reflect the three-for-two stock split.

  Net income for 1994 was $360 million or $3.14 per share compared to $323.8
million or $2.81 per share in 1993. Dividends on the 8%, 6.25% and Series C
preferred stock of $26.8 million in 1994 and dividends on the 8% and 6.25%
preferred stock of $24.5 million in 1993 have been deducted from net income to
compute earnings per share. Net income for fourth quarter 1994 amounted to $86
million or $0.74 per share compared to $77.9 million or $0.67 per share for
1993.

  Operating income amounted to $356.3 million or $3.10 per share, up from
$312.2 million or $2.70 per share in 1993. Operating income excludes after-tax
realized investment gains in 1994 and 1993. Aon's effective operating income
tax rate was 33% in 1994 and 31% in 1993, while realized gains were taxed at a
36% rate for both years. The 1993 annual tax provision also incorporated a
federal tax rate increase of one percentage point effective January 1, 1993
which caused a retroactive charge to deferred income tax of $5.4 million.

Liquidity

Aon's operating subsidiaries anticipate that there will be adequate liquidity to
meet their needs in the foreseeable future. Aon Corp.'s liquidity needs are
primarily for servicing its debt and for the payment of dividends on stock
issues. Dividends from Aon Corp.'s subsidiaries are the primary source for
meeting these requirements. There are certain regulatory restrictions relating
to dividend capacity of insurance subsidiaries that are discussed in note 7.
Insurance subsidiaries' statutory equity at year end 1994 again exceeded the
risk-based capital target set by the National Association of Insurance
Commissioners by a satisfactory level. At December 31, 1994, Aon Corp. had 
short-term lines of credit available in excess of $100 million.

  The businesses of Aon continue to provide substantial positive cash flow.
Brokerage cash flow has been used primarily for servicing acquisition-related
debt. Due to the contractual nature of its insurance policyholder liabilities
which are intermediate to long-term in nature, Aon has invested primarily in
investment-grade fixed maturities. Capital accumulation products are
interest-sensitive and require close duration matching. Non interest-sensitive
insurance products do not require as close monitoring of duration matching.
Because there is a reasonable duration match between these investments and
their related liabilities, changes in prevailing interest rates can, to a large
extent, be matched by congruent changes in credited interest rates resulting in
minimal impact on Aon's earnings. However, mismatches do occur. Aon will accept
a mismatch in duration in each individual segment but attempts to allow no more
than a one year mismatch when all interest-sensitive segments are aggregated.

  As of December 31, 1994, assets and interest-sensitive liabilities were
closely matched with the aggregate estimated duration variance of less than one
year. Through the use of derivative financial instruments (derivatives) (see
note 10), Aon improved its overall asset and liability duration match and
managed its interest rate risks. Given Aon's bond portfolio's average life of
7.6 years, access to lines of credit, and an uninterrupted trend in Aon's
positive cash flow, Aon expects sufficient cash flow to meet both short-term
and long-term cash needs. 

  Cash provided by operating activities in 1994 increased $91 million from
1993 to $695.8 million. This increase primarily reflects internal growth as
well as acquisitions related to brokerage operations.

  Investment activities used $361.5 million, down $312.3 million from prior
year primarily due to the use of cash at the brokerage operations as well as a
reduced level of funds made available from capital accumulation products. Cash
of approximately $100 million was provided from the issuance of long-term debt.
Proceeds from the debt issuance were used to retire $125 million of long-term
debt securities at par. Cash was used to pay dividends of $135.7 million on
common stock and Series B conversion preferred stock (PERCS), $18 million on 8%
preferred stock, $6.7 million on 6.25% preferred stock and $1.9 million on
Series C preferred stock.

  As of January 1, 1994, Aon adopted Statement of Financial Accounting
Standards (Statement) No. 115 "Accounting for Certain Investments in Debt and
Equity Securities." In accordance with Statement No. 115, Aon has segregated
its fixed maturity portfolio into two components: fixed maturities to be held
to maturity and fixed maturities available for sale. Fixed maturities that are
categorized as held to maturity are valued at amortized cost, while those
available for sale are carried at fair value with unrealized gains and losses
excluded from income and recorded directly as a separate component of
stockholders' equity. The after-tax stockholders' equity impact of reporting
fixed maturities available for sale at fair value was a net unrealized loss of
$111 million at December 31, 1994. To minimize the volatility of the changes in
this component of stockholders' equity, Aon enters into derivatives to hedge
its available for sale asset positions. In administering its hedging programs,
Aon performs analyses that have demonstrated that Aon achieves a high degree of
correlation.

</TABLE> 
Aon does not have any CMO residuals, interest only, inverse floating or
principal only type securities. CMOs have been acquired as alternatives to
mortgage-backed pass-through securities. Aon's insurance subsidiaries have
generally acquired shorter tranche CMOs classified in the form of sequential
payment, targeted amortization classes (TACs) or support TACs.

  Market values for CMOs are established each quarter based primarily on
information received from broker-dealer market makers. Certain mortgage-backed
securities are subject to duration extension risk during periods of rising
interest rates and to prepayment risk during periods of declining interest
rates. To limit its credit risk, Aon's CMO investments are concentrated in
tranches that have received an investment grade rating.

  Aon maintained separate investment reserves related to mortgage loan losses
on real estate and illiquid holdings which include real estate ventures,
limited partnerships and private placement common stocks totalling $36.4
million in 1994, down $14.9 million from the year end 1993 level of $51.3
million. These reserves are a product of Aon's continued review of the
characteristics and risks of its investment portfolio and current environmental
and economic conditions.

  Assets and liabilities held under special contracts increased $554 million
from 1993 primarily due to increased funds in variable life and annuity
programs. The net investment income generated from these assets is not included
in the consolidated statements of income.

Capital Resources

In 1994, notes payable decreased $25.8 million, reflecting the $125 million
repayment of public debt, the issuance of $100 million public debt, as well as
repayments on privately placed obligations. In addition, short-term borrowings
increased $75.3 million to satisfy Aon's short-term cash needs. This increase
was used primarily to finance the repurchase of common stock and the repurchase
of PERCS prior to mandatory conversion into common stock. The credit agreements
providing lines of credit for commercial paper contain no restrictive covenants.

  Aon Corp. continues to maintain an internal lending program with its various
subsidiaries where the parent company is able to borrow or lend funds. As of
December 31, 1994, Aon Corp. held notes payable to its subsidiaries of
approximately $373 million. These notes have interest rates in terms that were
competitive at the time of issuance.

  In 1994, stockholders' equity per common share decreased to $18.30, down from
$18.95 in 1993. The principal factors influencing this reduction were a $193.1
million increase in net unrealized investment losses, the exchange of 1,500,000
shares of common stock for Series C preferred stock and business combinations.
Excluding net income and dividends, another significant impact on equity was a
$41.3 million reduction in net unrealized foreign exchange losses.

Aon Corporation  |  Notes to Consolidated Financial Statements

1. Summary of Significant Accounting Principles 
   and Practices

Principles of Consolidation

The accompanying consolidated financial statements have been prepared in
conformity with generally accepted accounting principles and include the
accounts of Aon Corporation and its operating subsidiaries (Aon). All material
intercompany accounts and transactions have been eliminated.

Recognition of Premium Revenue and Related Expenses

For universal life-type and investment products, generally there is no
requirement for payment of premium other than to maintain account values at a
level sufficient to pay mortality and expense charges. Consequently, premiums
for universal life-type policies and investment products are not reported as
revenue, but as deposits. Policy fee revenue for universal life-type policies
and investment products consists of charges for the cost of insurance, policy
administration, and surrenders assessed during the period. Expenses include
interest credited to policy account balances and benefit claims incurred in
excess of policy account balances.

  In general, for accident and health, property and casualty and credit
products, premiums collected are reported as earned proportionately over the
period covered by the policies. For all other life products, premiums are
recognized as revenue when due. Benefits and related expenses associated with
premium revenues are charged to expense proportionately over the lives of the
policies through a provision for future policy benefit liabilities and through
deferral and amortization of deferred policy acquisition costs. In general, for
property and casualty and accident and health products, benefits and related
expenses associated with premium revenues are charged to expense as incurred.

Brokerage Commissions and Fees

In general, commission income is recognized at the later of the billing or
effective date of the related insurance policies. Contingent commissions,
certain life insurance commissions and commissions on premiums billed directly
by insurance companies are generally recognized as income when received.
Commissions on premium adjustments, including policy cancellations, are
recognized as they occur. Fees for claim administration services, benefit
consulting, reinsurance services and other services are recognized when the
services are rendered.

Reinsurance

Reinsurance premiums, commissions, and expense reimbursements on reinsured
business are accounted for on a basis consistent with those used in accounting
for the original policies issued and the terms of the reinsurance contracts.
Premiums and benefits ceded to other companies have been reported as a reduction
of premium revenue and benefits. Expense reimbursements received in connection
with reinsurance ceded have been accounted for as a reduction of the related
policy acquisition costs or, to the extent such reimbursements exceed the
related acquisition costs, as other revenue. All reinsurance receivables and
prepaid reinsurance premium amounts are reported as assets.

Income Tax

Deferred income tax has been provided for the effects of temporary differences
between financial reporting and tax bases of assets and liabilities and has been
measured using the enacted marginal tax rates and laws that are currently in
effect.

Earnings Per Share

Earnings per share are computed based on the weighted average number of common
and common equivalent shares outstanding during the respective period. Common
shares outstanding include 3,386,000 shares held by the employee stock ownership
plan. Common equivalent shares include Series A and Series B preferred stocks
and dilutive stock awards and stock options. The 8% cumulative perpetual
preferred stock (8% preferred stock), the 6.25% cumulative convertible
exchangeable preferred stock (6.25% preferred stock) and the Series C cumulative
preferred stock (Series C) are not considered common equivalent shares.
Accordingly, the dividends on the 8%, 6.25% and Series C preferred stock of $27
million in 1994 and the dividends on the 8% and 6.25% preferred stock of $25
million and $4 million in 1993 and 1992, respectively, have been deducted from
net income to compute earnings per share. There is no material difference
between primary and fully diluted per share amounts. Income attributable to
common stockholders is net of dividends on all preferred stock.

  A three-for-two stock split of Aon's $1.00 par value common stock was effected
on May 16, 1994 with 35 million shares issued to stockholders of record as of
May 3, 1994. All references in the accompanying financial statements and notes
to the number of common shares and per share amounts have been retroactively
restated to reflect the stock split.

Investments

Fixed maturities, where the intent is to hold to maturity, are carried generally
at amortized cost. As a result of adopting Statement of Financial Accounting
Standards (Statement) No. 115 "Accounting for Certain Investments in Debt and
Equity Securities" on January 1, 1994, fixed maturities that are available for
sale are carried at fair value at December 31, 1994. At December 31, 1993, fixed
maturities available for sale were carried, on an aggregate basis, at the lower
of amortized cost or fair value. The amortized cost of fixed maturities is
adjusted for amortization of premiums and accretion of discounts to maturity
that are included in net investment income. Included in fixed maturities are
investments in collateralized mortgage obligations (CMOs). Premiums and
discounts arising from the purchase of CMOs are treated as yield adjustments and
included in net investment income. Equity securities are valued at fair value.
Unrealized gains and temporary unrealized losses on fixed maturities available
for sale and equity securities are excluded from income and are recorded
directly to stockholders' equity, net of related deferred income taxes. Mortgage
loans are carried at amortized cost, net of reserves. Real estate is carried
generally at cost less accumulated depreciation. Policy loans are carried at
unpaid principal balance.


                                      38
<PAGE>


 
Other long-term investments are carried generally at cost. Realized investment
gains or losses are computed using specific costs of securities sold.

  Investments that have declines in fair value below cost, are judged to be
other than temporary, are written down to estimated fair values and reported as
realized investment losses. Additionally, reserves for mortgage loans and
certain other long-term investments are established based on an evaluation of
the respective investment portfolio, past credit loss experience, and current
economic conditions. Writedowns and reserves are included in realized investment
gains and losses in the statements of income. In general, Aon ceases to accrue
investment income where interest or dividend payments are in arrears.

  Accounting policies relating to derivative financial instruments are discussed
in note 10.

Deferred Policy Acquisition Costs

Costs of acquiring new and renewal business, principally the excess of new
commissions over renewal commissions, mass marketing advertising, underwriting
and sales expenses that vary with and are primarily related to the production of
new business, are deferred. For non-universal life-type products, amortization
of deferred acquisition costs and the cost of insurance purchased is related to
and based on the expected premium revenues on the policies. In general, such
amortization is adjusted to reflect current withdrawal experience. Expected
premium revenues are estimated by using the same assumptions used in estimating
future policy benefits. For property and casualty and short-duration health
insurance, costs of acquiring and renewing business, which are deferred, are
amortized as the related premium is earned.

  In general, deferred policy acquisition costs and cost of insurance purchased
related to universal life-type policies and investment products are amortized in
relation to the present value of expected gross profits on the policies. Such
amortization is adjusted periodically to reflect differences in actual and
assumed gross profits.

  To the extent that unrealized gains or losses on available for sale securities
would result in an adjustment of deferred policy acquisition costs had those
gains or losses actually been realized, the related deferred policy acquisition
cost adjustments are recorded along with the unrealized gains or losses included
in stockholders' equity with no effect on net income.

Other Intangible Assets

In general, the excess of cost over net assets purchased relating to business
acquisitions is being amortized into income over periods not exceeding forty
years using the straight-line method. The cost of insurance and renewal rights
purchased of certain subsidiaries is being amortized over a range of 2 to 30
years.

Property and Equipment

Property and equipment are generally depreciated using the straight-line method
over their estimated useful lives.

Fair Value of Financial Instruments

The following methods and assumptions were used to estimate fair values for
financial instruments. The carrying amounts in the consolidated statements of
financial position for cash and cash equivalents and short-term investments
approximate their fair values. Fair values for fixed maturity securities and
equity securities are based on quoted market prices or, if they are not actively
traded, on estimated values obtained from independent pricing services. The fair
values for mortgage loans and policy loans are estimated using discounted cash
flow analyses, using interest rates currently being offered for similar loans to
borrowers with similar credit ratings. Fair values of derivatives are based on
quoted prices for exchange-traded instruments or the cost to terminate or offset
with other contracts.

  In general, other long-term investments are comprised of real estate joint
ventures and limited partnerships. It was not practicable to estimate the fair
value of other long-term investments because of the lack of quoted market prices
and the inability to estimate fair value without incurring excessive costs. In
addition, the determination of the fair value of investment commitments was
deemed impractical due to the inability to estimate future cash flows.

  Fair values for liabilities for investment-type contracts are estimated using
discounted cash flow calculations based on interest rates currently being
offered for similar contracts with maturities consistent with those remaining
for the contracts being valued. The fair value of notes payable are based on
quoted market prices for the publicly traded portion and on estimates using
discounted cash flow analyses based on current borrowing rates for similar types
of borrowing arrangements for the non-publicly traded portion.

Assets and Liabilities Held Under Special Contracts

Assets held under special contracts principally represent designated funds of
group pension, variable life, annuity and unit-linked policyholders. These
assets are offset by liabilities that represent such policyholders' equity in
those assets. The net investment income generated from these assets is not
included in the consolidated statements of income.

Future Policy Benefits, Unearned Premiums and Policy and Contract Claims

Future policy benefit liabilities on non-universal life-type and accident and
health products have been provided on the net level premium method. The
liabilities are calculated based on assumptions as to investment yield,
mortality, morbidity, and withdrawal rates that were determined at the date of
issue, and provide for possible adverse deviations. Interest assumptions are
graded and range from 9% to 4.5%. Withdrawal assumptions are based principally
on insurance subsidiaries' experience and vary by plan, year of issue, and
duration.

  Policyholder liabilities on universal life-type and investment products are
generally based on policy account values. Interest credit rates for these
products range from 8.4% to 5.6%.

  Unearned premiums generally are calculated using the pro rata method based on
gross premiums. However, in the

                                      39
<PAGE>


 
case of credit life, credit accident and health, and extended warranty products,
the unearned premiums are calculated such that the premiums are earned over the
period of risk in a reasonable relationship to anticipated claims.

  Policy and contract claim liabilities represent estimates for reported claims,
as well as provisions for losses incurred, but not yet reported. These claim
liabilities are based on historical experience and are estimates of the ultimate
amount to be paid when the claims are settled. Changes in the estimated
liability are reflected in income as the estimates are revised.

Foreign Currency Translation

Foreign revenues and expenses are translated at average exchange rates. Foreign
assets and liabilities are translated at year end exchange rates. Unrealized
foreign exchange losses on translation are generally reported in stockholders'
equity, net of deferred income tax credit of $11 million, $33 million and $20
million at December 31, 1994, 1993 and 1992, respectively.

Accounting Changes

On January 1, 1994, Aon adopted Statement No. 115 which requires categorization
of fixed maturities either as held to maturity, available for sale or trading
and equity securities as available for sale or trading. Investments in fixed
maturities and equity investments, that are categorized as available for sale,
are carried at fair value, with unrealized gains and losses (net of applicable
tax and adjustment to amortization of deferred policy acquisition costs)
excluded from income and recorded directly as a separate component of
stockholders' equity. Aon does not categorize any fixed maturities or equity
securities as trading.

  The adoption of Statement No. 115 had no effect on Aon's accounting for equity
securities. In accordance with Statement No. 115, prior period financial
statements have not been restated to reflect the change in accounting principle.

  In addition, Aon adopted Statement No. 112, "Employers' Accounting for
Postemployment Benefits" in 1994. Implementation of this Statement did not have
a material effect on Aon's financial statements. Aon adopted Statement No. 106,
"Employers' Accounting for Postretirement Benefits Other Than Pensions" (note 8)
and Statement No. 109, "Accounting for Income Taxes" (note 5) in 1992.

  The Financial Accounting Standards Board has issued Statements No. 114 and 118
which relate to accounting by creditors for impairment of a loan. The Statements
require that impaired loans are to be valued at the present value of expected
future cash flows, at the loan's observable market price, or at the fair value
of the collateral if the loan is collateral dependent. Aon anticipates adopting
these Statements in its 1995 financial statements as required. Implementation of
these Statements is not expected to have a material effect on Aon's financial
statements.

2. Business Combinations

Pooling of Interests Method

In the fourth quarter of 1994, Aon issued 3,540,000 shares of common stock for
the mergers with the insurance brokerage organizations of Jenner Fenton Slade
Limited (JFS) and Energy Insurance International, Inc. (EII). In connection with
these poolings, 325,000 shares are being held in escrow pending the resolution
of contingencies.

  In addition, in 1994, 1993 and 1992, Aon issued 2,006,000 shares, 1,044,000
shares and 1,673,000 shares of common stock, respectively, for the mergers with
certain other insurance brokerage organizations. In connection with several of
the 1994 mergers, 255,000 shares are being held in escrow pending the resolution
of contingencies. Aon's prior period financial statements have not been restated
because the effect of the above mergers was not material.

Purchase Method

In November 1992, Aon acquired certain assets and assumed certain liabilities of
Frank B. Hall and Co., Inc. (Hall) for approximately $500 million. This
acquisition was financed with the issuance of 9 million shares of 8% preferred
stock, 2,374,000 shares of 6.25% preferred stock, and cash. Based on the
resolution in 1993 of certain issues related to the purchase of the assets of
Hall, Hall returned 238,000 shares of 6.25% preferred stock to Aon, which were
retired. In accordance with the purchase agreement, securities with a value of
$125 million are being held in escrow. The escrowed securities will be released
on a pre-determined schedule between 1997 and 2007. The statements of income
include the operations of Hall since the transaction date.

  In 1992, Aon recorded special charges for employee reductions, which primarily
included an early retirement program and the consolidation of certain brokerage
offices as a result of the acquisition of the assets of Hall. The above charges
aggregated $87 million before income taxes.

  In addition, during 1994, 1993 and 1992, subsidiaries of Aon acquired certain
insurance brokerage and consulting services operations that were financed
primarily by internal funds and the reissuance of common stock from treasury.
Pursuant to a 1994 purchase agreement with one of the brokerage operations, over
the next six years, Aon is contingently liable to issue up to 249,000 additional
shares of common stock based on a formula relating to future earnings of that
operation. The aggregate cost of these acquisitions was $22 million, $176
million and $153 million in 1994, 1993 and 1992, respectively. The proforma
results of these operations, as if the acquisitions had occurred as of the
beginning of the year, have an immaterial effect on Aon's consolidated revenues
and net income.

</TABLE> 
Gross gains of $68 million, and gross losses of $51 million, were realized
on available for sale fixed maturities and equity securities sales during 1994.
Gross gains of $11 million, and gross losses of $7 million, were realized on
sales of held to maturity fixed maturities during 1994. Gross gains of $63
million and $48 million and gross losses of $35 million and $30 million were
realized on fixed maturity sales during 1993 and 1992, respectively.

  The cumulative effect of the adoption of Statement No. 115 increased
stockholders' equity by $148 million (net of adjustments to deferred policy
acquisition costs of $14 million and deferred income taxes of $83 million) to
reflect the net unrealized fixed maturities holding gains on securities
previously carried at amortized cost; there was no effect on net income as a
result of the adoption. During 1994, those holding gains decreased by $259
million (net of adjustments to deferred policy acquisition costs of $44
million and deferred income taxes of $100 million) to a net unrealized loss of
$111 million.

  In connection with the adoption of Statement No. 115, Aon reclassified
certain fixed maturity investments with an amortized cost of $1,984 million and
fair value of $2,149 million from held to maturity to available for sale.
Subsequent to January 1, 1994 there were no additional reclassifications
between available for sale and held to maturity.

  The changes in net unrealized gains (losses) on fixed maturities and equity
security investments are as follows:

Net unrealized investment losses at December 31, 1994 of $143 million are
net of deferred income tax credit of $45 million and a $20 million after-tax
deferred policy acquisition cost adjustment. Net unrealized investment gains at
December 31, 1993 of $50 million are net of a deferred income tax charge of $31
million.

  The amortized cost and fair value of fixed maturities, by contractual
maturity, are shown below. Expected maturities will differ from contractual
maturities because borrowers may have the right to call or prepay obligations
with or without call or prepayment penalties.

===============================================================
</TABLE> 

Interest is payable semiannually on all debt securities. In addition, the
debt securities are not redeemable by Aon prior to maturity and contain no
sinking fund provisions.

  Maturities of notes payable are $22 million in 1995, $9 million in 1996, 1997
and 1998 and $101 million in 1999.

  Interest expense was $35 million in 1994 and $36 million in 1993 and 1992.
Total interest paid on debt for 1994, 1993 and 1992 was $44 million, $41 million
and $40 million, respectively.

Guaranteed Debt

During 1989, Aon's employee stock ownership plan (ESOP) entered into loan
agreements amounting to $90 million to purchase Aon common stock. The ESOP
paid $13 million in 1994 and $12 million in 1993 and 1992, in loan principal and
interest from contributions made by Aon to the ESOP as well as dividend proceeds
of common stock held by the ESOP. The loans have an interest rate of 8.35% and
serially mature through 1999. Interest expense incurred by the ESOP related to
these loans amounted to $6 million in 1994 and $7 million in 1993 and 1992. The
loans are unconditionally guaranteed by Aon and therefore the unpaid balance of
the loans is reflected as debt in the accompanying statements of financial
position. An equivalent amount, representing deferred compensation, is recorded
as a deduction from stockholders' equity. Future contributions, as determined by
Aon's Board of Directors, plus dividends earned on shares held by the ESOP will
be used to service the loans.

Lease Commitments

Aon has noncancelable operating leases for certain office space, equipment
and automobiles. Future minimum rental payments required under operating leases
that have initial or remaining noncancelable lease terms in excess of one year
at December 31, 1994 are as follows:

</TABLE> 

As of December 31, 1994, the deferred tax asset relating to unrealized
investment losses is net of a $30 million valuation allowance that was provided
directly in stockholders' equity in 1994.

  Prior to 1984, the life insurance companies were required to accumulate
certain untaxed amounts in a memorandum "policyholders' surplus account." Under
the Tax Reform Act of 1984, the "policyholders' surplus account" balances were
"capped" at December 31, 1983 and the balances will be taxed only to the extent
distributed to stockholders or when they exceed certain prescribed limits. As of
December 31, 1994, the combined "policyholders' surplus account" of Aon's life
insurance subsidiaries approximates $363 million. Aon's life insurance
subsidiaries do not intend to make any taxable distributions or exceed the
prescribed limits in the foreseeable future; therefore, no income tax provision
has been made. However, if such taxes were assessed, the amount of tax payable
would be $127 million.

  The amount of income taxes paid for 1994, 1993 and 1992 was $167 million, $130
million and $105 million, respectively.

  Effective January 1, 1992, Aon changed its method of accounting for income
taxes from the deferred method to the liability method required by Statement No.
109, "Accounting for Income Taxes." The cumulative effect of adopting Statement
No. 109 for periods prior to January 1, 1992 was to decrease 1992 net income by
$40 million ($0.38 per share).

6. Reinsurance and Claim Reserves

Aon's insurance subsidiaries are involved in both the cession and assumption of
reinsurance with other companies. Aon's reinsurance consists primarily of short-
duration contracts that are entered into with numerous automobile dealerships
and financial institutions. Aon's insurance subsidiaries would remain liable to
the extent that the reinsuring companies are unable to meet their obligations.
Ceded premiums earned were $415 million, $408 million and $414 million for 1994,
1993 and 1992, respectively, while ceded premiums written were $408 million and
$420 million for 1994 and 1993, respectively. Assumed premiums earned were $213
million, $184 million and $228 million for 1994, 1993 and 1992, respectively,
while assumed premiums written were $218 million and $176 million for 1994 and
1993, respectively. Benefits to policyholders are net of $247 million and $211
million in reinsurance recoveries during 1994 and 1993, respectively.

  Activity in the liability for policy contract claims is summarized as
follows:

7. Redeemable Preferred Stock and Stockholders' Equity

Redeemable Preferred Stock

In 1994, Aon issued 1,000,000 shares of Series C preferred stock to a former
officer in exchange for 1,500,000 shares of Aon common stock. Dividends are
cumulative at an annual rate of $2.55 per share. Dividends incurred were
$2 million in 1994. The shares of Series C preferred stock will be redeemable at
the option of Aon (by resolution of its Board of Directors) or the holders, in
whole or in part, at $50.00 per share no sooner than February 9, 1999.

Common Stock

Aon recorded dividends to common stockholders of $129 million, $118 million and
$112 million in 1994, 1993 and 1992, respectively. In addition, Aon repurchased
844,000, 16,000 and 395,000 shares, in 1994, 1993 and 1992, respectively, of its
common stock, primarily to provide shares for stock compensation plans and the
conversion of the Series B conversion preferred stock.

Series B Conversion Preferred Stock

In 1991, Aon issued 2,800,000 shares of $3.04 cumulative Series B conversion
preferred stock (Series B preferred stock). Aon repurchased 1,210,000 shares and
151,000 shares of its outstanding stock for $58 million and $7 million in 1994
and 1993, respectively. These shares were cancelled and retired. Aon recorded
dividends of $6 million, $8 million and $9 million in 1994, 1993 and 1992,
respectively. At December 1, 1994, 1,439,000 shares were outstanding and each
share of stock was automatically converted, pursuant to the stock's terms, into
one and one half shares of common stock issued from treasury.

8% Cumulative Perpetual Preferred Stock

In 1992, Aon issued 9,000,000 shares of cumulative perpetual 8% preferred stock.
Dividends are cumulative at the annual rate of $2.00 per share. Dividends
incurred were $18 million in 1994 and 1993 and $3 million in 1992. At its
option, Aon may redeem all or any part of the stock at any time on or after
November 1, 1997 at a redemption price of $25.00 per share plus all accrued and
unpaid dividends. The holders of the stock have limited voting rights. 

6.25% Cumulative Convertible Exchangeable Preferred Stock 

In 1992, Aon issued 2,374,000 shares of 6.25% cumulative convertible
exchangeable preferred stock. At December 31, 1994, 2,136,000 shares are
outstanding. Dividends are cumulative at the annual rate of $3.125 per share.
Dividends incurred were $7 million in 1994 and 1993 and


                                      43

<PAGE>
 
$1 million in 1992. The stock is convertible at any time at the option of the
holder into 1.22 shares of common stock for each share. The stock is
exchangeable at Aon's option, in whole but not in part, on any dividend payment
date commencing November 1, 1996 for 6.25% convertible subordinated debentures
due November 1, 2022 at the rate of $50.00 principal amount of the debentures
for each share. At its option, Aon may redeem all or any part of the stock,
unless previously converted or exchanged, on or after November 1, 1996 at prices
ranging from $51.875 per share in 1996 declining to $50.00 per share in 2002 and
thereafter, plus accrued and unpaid dividends. The holders of the stock have
limited voting rights.

Statutory Capital and Surplus

Generally, the capital and surplus of Aon's insurance subsidiaries available for
transfer to the parent company are limited to the amounts that the insurance
subsidiaries' statutory capital and surplus exceed minimum statutory capital
requirements; however, payments of the amounts as dividends may be subject to
approval by regulatory authorities. See note 5 for possible tax effects of
distributions made out of untaxed earnings. Net income of Aon's insurance
subsidiaries, as determined using statutory accounting practices, amounted to
$272 million, $255 million and $187 million for the life insurance companies and
$34 million, $62 million and $42 million for the property and casualty companies
for the years ended December 31, 1994, 1993 and 1992, respectively. Statutory
stockholders' equity of Aon's direct life insurance subsidiaries amounted to
$714 million and $561 million at December 31, 1994 and 1993, respectively.
Statutory stockholders' equity of property and casualty insurance companies
amounted to $284 million and $251 million at December 31, 1994 and 1993,
respectively.

8. Employee Benefits 

Savings and Profit Sharing Plans

Certain of Aon's subsidiaries maintain a contributory savings plan for the
benefit of United States salaried and commissioned employees and a contributory
profit sharing plan for the benefit of Canadian salaried employees and
commissioned agents. The company contribution for the savings plan is based on a
match of 100% of employee contributions up to a maximum of 3% of eligible
compensation. Provisions made for these plans were $14 million in 1994 and 1993
and $11 million in 1992.

  During 1993, the Hall savings and investment plan, the Booke & Company salary
deferral thrift plan and the K&K Insurance Agency, Inc. 401(k) profit sharing
trust were merged into the Aon savings plan.

Employee Stock Ownership Plan

Certain of Aon's subsidiaries maintain a leveraged ESOP for the benefit of
the United States salaried and certain commissioned employees. Shares are
allocated to eligible employees over a period of ten years through 1998.
Contributions to the ESOP and charged to income amounted to $10 million in 1994
and $9 million in 1993 and 1992.

Domestic Pension Plan

Certain of Aon's subsidiaries maintain a non-contributory defined benefit
pension plan providing retirement benefits for salaried employees and certain
commissioned employees in the United States based on years of service and
salary. Aon's funding policy is to contribute amounts to the plan sufficient to
meet the minimum funding requirements set forth in the Employee Retirement
Income Security Act of 1974, plus such additional amounts as Aon determines to
be appropriate from time to time. A summary of the components of net periodic
pension cost for the defined benefit plans in 1994, 1993 and 1992 is as follows:

In December 1992, as part of an employee reduction program, Aon established a
limited time early retirement incentive program that provided benefits through
the defined benefit plan. The additional cost of termination benefits applicable
for 1992 resulting from the program was $13 million.

  During 1993, the assets and liabilities of the Pension Plan for the Employees
of Booke & Company were merged with the Aon Pension Plan as a result of the
merger of Booke & Company with an Aon subsidiary. Also, the Aon Pension Plan was
amended in 1993 to include certain additional amounts of compensation in
determining plan benefits and in 1994 to reduce the maximum amount of
compensation that can be considered under the plan as required by law. Further
the Pension Plan was amended in 1994 to provide increases in benefits to current
pensioners. Net periodic pension cost for 1994 decreased $2 million and
increased $2 million in 1993 as a result of these amendments.

  The following table sets forth the funded status and amounts recognized in the
consolidated statements of financial position for Aon's U.S. defined benefit
pension plan.

Plan assets include marketable equity securities, deposit administration
insurance contracts, and corporate and government debt securities. Included are
securities issued by Aon totaling $18 million in 1994 and 1993. In addition,
$143 million of plan assets are held under a special contract with a subsidiary
of Aon in 1994.

Foreign Pension Plans

Certain of Aon's foreign subsidiaries maintain contributory and non-contributory
defined benefit pension plans for employees outside of the United States that
provide retirement benefits based on service and salary. Material plans are
maintained in the United Kingdom and The Netherlands. The funding policy for
these plans is to contribute the amounts required by the plan provisions or
applicable regulations, although additional amounts may be contributed from time
to time. A summary of the components of net periodic pension cost for the
material defined benefit plans in 1994 and 1993, grouped by country, is as

In 1992, the only significant foreign pension plans were the European
brokerage plans. Aon recorded a net periodic pension credit for 1992 of
approximately $1 million. These plans used an assumed discount rate of 8%, a
rate of compensation increase of 6%, and an expected long-term rate of return
on plan assets of 8%. 

Postretirement Benefits Other Than Pensions

Aon sponsors defined benefit postretirement health and welfare plans that cover
both salaried and nonsalaried employees in the U.S., as well as certain other
salaried employees in Canada. In the U.S., one plan provides medical benefits,
prior to and subsequent to Medicare eligibility, and the other provides life
insurance benefits. In Canada, the plans provide both extended health care
benefits and life insurance benefits. The postretirement health care plans are
contributory, with retiree contributions adjusted annually; the life insurance
plans are noncontributory. All plans are funded on a pay-as-you go basis.

  In 1993, the accounting for the U.S. health care plan reflected changes in the
future cost-sharing provisions of the plan. These changes limited the employer's
liability for future plan cost increases in any year to 5% per annum. In prior
years, Aon anticipated that the retiree's share of future cost would increase at
the same rate as the employer's share.

  In 1992, Aon adopted Statement No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions." Aon recorded a cumulative effect
change for adopting Statement No. 106 in the amount of $40 million ($0.38 per
share), which is net of income taxes of $20 million, in the 1992 statement of
income. The recorded amount represented the cumulative postretirement benefit
obligation for periods prior to January 1, 1992.

================================================================================
</TABLE> 

For measurement purposes in 1994 and 1993, an 11.5% and 12.5%, respectively,
annual rate of increase in the per capita cost of covered health care benefits
(trend rate) adjusted for actual current year cost experience was assumed,
decreasing gradually to 7% in year 2000 and remaining the same thereafter.
However, with the employer funding increase cap limited to 5% per year, net
employer trend rates are effectively limited to 5% per year in the future. For
measurement purposes in 1992, a 14.5% trend rate was assumed, decreasing
gradually to 7% in year 2000 and remaining the same thereafter.

  Increasing the assumed health care cost trend rates by one percentage point
would result in a negligible change in the accumulated postretirement benefit
obligation (APBO) as of December 31, 1994 because of the 5% cap on future
employer funding increases for domestic medical plans.

  The weighted-average discount rate used in determining the APBO was 8.5%, 7.0%
and 8.0% at December 31, 1994, 1993 and 1992, respectively. The weighted-average
rate of compensation increase used in determining the APBO for the
postretirement life insurance plan was 5.0%, 5.5% and 6.0% at December 31, 1994,
1993 and 1992, respectively.

9. Stock Compensation Plans

Stock Award Plan

In 1994, Aon's stockholders approved an amendment to the Aon Stock Award Plan
that increases the aggregate number of shares of common stock that Aon can award
from 1,350,000 to 3,350,000 shares. Generally, the award plan requires the
employees to complete three continuous years of service before the award begins
to vest in increments until the completion of a ten year period of continuous
employment. All awarded shares are issued as they become vested. With certain
limited exceptions, any break in continuous employment will cause forfeiture of
all unvested awards. During 1994, 1993 and 1992, Aon awarded 801,000, 539,000
and 401,000 shares, respectively. At December 31, 1994, 1993 and 1992, 587,000,
372,000 and 265,000 shares awarded under the Stock Award Plan have vested and
been issued. The compensation cost associated with each award is deferred and
amortized over the period of continuous employment using the straight line
method. Aon awarded shares aggregating a net deferred compensation cost of $18
million in 1994 and 1993 and $11 million in 1993, that was included as an
increase in paid-in additional capital with an equal amount deducted from
stockholders' equity (deferred compensation). Amortization of deferred
compensation cost totaled $6 million, $4 million and $6 million in 1994, 1993
and 1992, respectively.

Stock Option Plan

Under a nonqualified stock option plan, options to purchase common stock were
granted to certain officers and employees of Aon and its subsidiaries at 100% of
market value on the date of grant. Common stock options outstanding consisted of
the following:

10. Financial Instruments

Derivative Financial Instruments

Aon uses interest rate derivative contracts to manage the interest rate and
asset and liability duration risks on certain life and annuity and premium
finance businesses. Aon does not engage in trading of derivatives. In addition,
Aon purchased interest rate caps to limit interest expense on short-term
borrowings. Exchange-traded interest rate futures and options are used
primarily as a hedge against the value of Aon's available for sale fixed
maturity and equity investments. As of December 31, 1994, Aon was selling
futures  as well as writing call options and limiting its risk on these written
options to a spread by purchasing call options. Exchange traded futures and
options are valued and settled daily. The premium that Aon pays for purchased
options and receives for written options represents the cost basis of the
option until it expires or is closed.


                                      46
<PAGE>
 
  Interest rate swap agreements are used primarily to manage asset and
liability durations relating to capital accumulation life and annuity business.
As of December 31, 1994, Aon was paying fixed rates and receiving variable
rates on interest rate swap contracts with the effect of lengthening liability
durations. The net effect of interest rate swap payments is settled
periodically and reported in income. There is no settlement of underlying
notional amounts. Aon also used interest rate options and swaps to hedge
against interest rate movements until certain anticipated debt was issued.

  Aon performs frequent analysis to measure the degree of correlation
associated with its derivative programs. Aon assesses the adequacy of the
correlation analysis results in determining whether the derivatives qualify for
hedge accounting. Realized gains and losses on derivatives that qualify as
hedges are deferred and reported as an adjustment of the cost basis of the
hedged item. Deferred gains and losses are amortized into income over the life
of the hedged item. Outstanding derivatives that are hedges of items carried at
fair value are reflected in the financial statements with the derivative fair
value reported as unrealized gains and losses directly in stockholders' equity.

  Aon uses foreign currency futures, options, and forward contracts to hedge
against the effects of foreign currency fluctuations on the translation of the
financial statements of Aon's foreign operations. Generally, realized and
unrealized gains and losses on those derivatives are recorded directly to
stockholders' equity, as a separate component of net unrealized foreign
exchange gains and losses.

  Certain of Aon's foreign brokerage subsidiaries receive revenues in
currencies that differ from the currency in which their operating costs are
denominated. To reduce the variability of cash flows from these operations,
foreign forward exchange contracts having settlement dates that are primarily
less than one year are used. Related gains or losses on these contracts are
reflected as an adjustment to the expense component on the statement of income
when the currencies are exchanged to settle expense commitments. Contracts
entered into require no up-front premium and settle at the expiration of the
related contract.

  The following are the notional amounts of Aon's outstanding derivatives
grouped by the types of risks being managed:

  During 1994, Aon amortized $3 million of deferred gains relating to
derivatives into income. Deferred losses related to anticipated transactions
were immaterial at December 31, 1994.

  The interest rates on Aon's principal outstanding swaps at December 31 are
presented below.

===============================================================================
</TABLE> 

As of December 31, 1994, the principal swaps have maturities ranging from
October 1998 to October 2000 and variable rates based on the five-year treasury
rate. As of December 31, 1993, Aon paid variable rates based on the three and
six month LIBOR index. Other outstanding derivative contracts generally have
lives that are 90 days or less. 

Aon is exposed to credit risk of derivative contracts in the event of
nonperformance by the counterparties to the financial instruments. The credit
risk is generally limited to the fair value of those contracts that are
favorable to Aon. Aon has limited its credit risk by restricting investments in
derivative contracts to a diverse group of highly rated major financial
institutions and by using exchange-traded instruments. At December 31, 1994 and
1993, Aon placed securities in escrow amounting to $21 million and $8 million,
respectively, relating to these derivative contracts.

Other Financial Instruments

Aon has certain investment commitments to provide capital and fixed-rate
loans as well as certain forward contract purchase commitments. The investment
commitments, which would be collateralized by related properties of the
underlying investments, involve varying elements of credit and market risk.
Investment commitments outstanding at December 31, 1994 and 1993 totalled $134
million and $481 million, respectively.

  Subsidiaries of Aon have entered into agreements with financial institutions,
whereby the subsidiaries sold certain receivables, with limited recourse.
Agreements provide for sales of receivables on a continuing basis through
November 1995. As of December 31, 1994 and 1993, the maximum commitment
contained in these agreements was $525 million and $400 million, respectively.
Accounts receivable sold in 1994, 1993 and 1992, amounted to $1,095 million,
$879 million and $671 million, respectively. Outstanding receivables of $512
million and $401 million, remained to be collected at December 31, 1994 and
1993, respectively. Aon's credit risk relates to amounts that may be due under
recourse provisions that could exceed recorded estimates. At December 31, 1994
and 1993, this exposure was approximately $34 million and $41 million,
respectively.

Fair Value of Financial Instruments

Accounting standards require the disclosure of fair values for certain
financial instruments. The fair value disclosures are not intended to encompass
the majority of policy liabilities, various other non-financial instruments, or
other intangible items related to Aon's business. Accordingly, care should be
exercised in deriving conclusions about Aon's business or financial condition
based on the fair value disclosures. The carrying value and fair value of
certain of Aon's financial instruments are as follows:

11. Litigation

Aon and its subsidiaries are subject to numerous claims and lawsuits that arise
in the ordinary course of business. In some of these cases, the remedies that
may be sought or damages claimed are substantial, including cases which seek
punitive or extraordinary damages. Accruals for these lawsuits have been
provided to the extent that losses are deemed probable and are estimable.
Although the ultimate outcome of these suits cannot be ascertained and
liabilities in indeterminate amounts may be imposed on Aon or its subsidiaries,
on the basis of present information, availability of insurance coverages, and
advice received from counsel, it is the opinion of management that the
disposition or ultimate determination of such claims and lawsuits will not have
a material adverse effect on the consolidated financial position of Aon.

Report of Ernst & Young LLP, Independent Auditors
Board of Directors and Stockholders
Aon Corporation

We have audited the accompanying consolidated statements of financial position
of Aon Corporation as of December 31, 1994 and 1993, and the related
consolidated statements of income, stockholders' equity, and cash flows for each
of the three years in the period ended December 31, 1994. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Aon Corporation at
December 31, 1994 and 1993, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended December 31,
1994, in conformity with generally accepted accounting principles.

  As discussed in notes 3, 5 and 8, the Company changed its method of accounting
for certain investments in 1994 and income taxes and postretirement benefits
other than pensions in 1992.

Report by Management

The management of Aon Corporation is responsible for the financial
statements and other financial information in the annual report and for their
integrity and objectivity. The statements have been prepared in conformity with
generally accepted accounting principles. These statements include informed
estimates and judgments for those transactions not yet complete or for which
the ultimate effects cannot be measured precisely. Financial information
elsewhere in this report is consistent with that in the financial statements.
The consolidated financial statements have been audited by our independent
auditors. Their role is to render an independent professional opinion on Aon's
financial statements.

  Management maintains a system of internal control designed to meet its
responsibilities for reliable financial statements. The system is designed to
provide reasonable assurance, at appropriate costs, that assets are safeguarded
and that transactions are properly recorded and executed in accordance with
management's authorization. Judgments are required to assess and balance the
relative costs and expected benefits of those controls. It is management's
opinion that its system of internal control, as of December 31, 1994, was
effective in providing reasonable assurance that its financial statements were
free of material misstatement. In addition, management supports and maintains a
professional staff of internal auditors who coordinate audit coverage with the
independent auditors and conduct an extensive program of financial and
operational audits.

  The Board of Directors selects an Audit Committee from among its members. No
member of the Audit Committee is an employee of Aon. The Audit Committee is
responsible to the Board for reviewing the accounting and auditing procedures
and financial practices of Aon and for recommending appointment of the
independent auditors. The Audit Committee meets periodically with management,
internal auditors and independent auditors to review the work of each and
satisfy itself that they are properly discharging their responsibilities. Both
the independent auditors and the internal auditors have free access to the
Committee, without the presence of management, to discuss the adequacy of
internal control and to review the quality of financial reporting.

              CONSENT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

We consent to the incorporation by reference in this Annual Report (Form 10-K)
of Aon Corporation of our report dated February 9, 1995, included in the 1994
Annual Report to Stockholders of Aon Corporation.

Our audits also included the financial statement schedules of Aon Corporation 
listed in Item 14(a). These schedules are the responsibility of the Company's 
management. Our responsibility is to express an opinion based on our audits. In 
our opinion, with respect to which the date is February 9, 1995, the financial 
statement schedules referred to above, when considered in relation to the basic 
financial statements taken as a whole, present fairly in all material respects 
the information set forth therein. As discussed in Notes 3, 5 and 8 to the 
consolidated financial statements in the 1994 Annual Report to Stockholders of 
Aon Corporation, the Company changed its method of accounting for certain 
investments in 1994 and income taxes and postretirement benefits other than 
pensions in 1992.

We also consent to the incorporation by reference in the Registration Statements
pertaining to the employer's stock option and savings plans (Form S-8 Nos. 
2-79114, 2-82791, 33-27984, and 33-42575) and the right to offer preferred stock
(Form S-3 No. 33-57562) of Aon Corporation of our report dated February 9, 
1995, with respect to the consolidated financial statements incorporated herein 
by reference, and our report, included in the preceding paragraph with respect 
to the financial statement schedules included in this Annual Report (Form 10-K) 
of Aon Corporation.
