                                     PART I

ITEM 1.  BUSINESS.

         The Registrant is a holding company whose operating  subsidiaries carry
on business in two distinct  segments:  (i) insurance  brokerage and  consulting
services,  and (ii)  insurance  underwriting.  Incorporated  in 1979,  it is the
parent corporation of long-established and more recently formed companies.

         Aon  Group,   Inc.,  its   subsidiaries   and  certain  other  indirect
subsidiaries  of the  Registrant  (the "Aon Group")  including Aon Risk Services
Companies,  Inc.; Aon Holdings bv; Aon Consulting Worldwide,  Inc.; Aon Services
Group, Inc.; Aon Re Worldwide,  Inc.; and Aon Group Limited provide  reinsurance
intermediary  services,  benefits consulting and commercial  insurance brokerage
services. Aon Group revenues grew significantly in fiscal 1996 and 1997 when the
Registrant acquired, among other companies, Bain Hogg Group plc in October 1996,
Alexander & Alexander  Services  Inc.  in January  1997,  The Minet Group in May
1997, and Jauch & Hubener in November 1997.

         Combined Insurance Company of America ("Combined Insurance") engages in
the  marketing  of life and  accident and health  insurance  products.  Virginia
Surety Company, Inc. and London General Insurance Company Limited offer extended
warranty and specialty insurance products.

         In second quarter 1996, the Registrant and Combined  Insurance sold two
of Combined Insurance's  insurance  subsidiaries,  Union Fidelity Life Insurance
Company ("UFLIC") and the Life Insurance Company of Virginia ("LOV").  In second
quarter 1996,  Ryan  Insurance  Group,  Inc. sold its North American auto credit
underwriting  and  distribution  businesses,  including the distribution of auto
extended warranty products.

         The Registrant  hereby  incorporates by reference pages 7 through 16 of
the Annual Report to  Stockholders  of the Registrant for the Year 1997 ("Annual
Report").

COMPETITION AND INDUSTRY POSITION

(1)  INSURANCE BROKERAGE AND CONSULTING SERVICES

         Aon Group, Inc. ("Aon Group"); Aon Risk Services Companies,  Inc. ("Aon
Risk Services Companies"); Aon Holdings bv ("Aon Holdings"); Aon Services Group,
Inc. ("Aon Services Group"); Aon Consulting Worldwide,  Inc. ("Aon Consulting");
Aon Re Worldwide, Inc. ("Aon Re"); Aon Group Limited ("AGL").

         Aon  Group  is the  holding  company  for the  Registrant's  commercial
brokerage and  consulting  operation.  Aon Group is the fastest  growing  global
insurance  brokerage and  consulting  services firm in the world.  The Aon Group
companies  have  more  than  550  offices  around  the  world  in more  than 100
countries.  In 1997,  Aon Group employed over 33,000  professionals  and support
personnel to serve the diverse needs of clients.

         Aon  Risk  Services  Companies'   (formerly  Rollins  Hudig  Hall  Co.)
subsidiaries  operate in a highly competitive  industry and compete with a large
number of retail  insurance  brokerage  and agency  firms as well as  individual
brokers and agents and direct writers of insurance  coverage.  Aon Risk Services
Companies'  subsidiaries  offer  comprehensive  services  to  clients  including
insurance  placement,  specialized  brokerage services,  program development and
administration,  premium  financing  services,  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, media and entertainment.

         Subsidiaries  of Aon Risk Services  Companies and Aon Holdings  operate
through owned offices in North America and Europe,  as well as in South America,
Africa,  Australia and Asia. The acquisitions of A&A and Bain Hogg significantly
augmented  the  Registrant's  presence  in  Latin  America,   Asia,  Africa  and
Australia,  and the acquisition of Jauch & Hubener strengthened the Registrant's
presence throughout Europe.

         Aon Services Group (formerly Aon Specialty  Group) addresses the highly
specialized  product   development,   consulting  and  administrative  needs  of
professional groups, service businesses, governments,  health-care providers and
commercial  organizations.  It also  provides  underwriting  management  skills,
claims and risk management expertise, and third-party administration services to
insurance companies. Aon Services Group operating subsidiaries market and broker
both the primary and reinsurance  risks of these  programs.  For individuals and
businesses,  Aon Services  Group  provides  affinity  products for  professional
liability,  life and personal  lines.  The acquisition of The Minet Group by the
Registrant  will  augment Aon  Services  Group's  already  strong  expertise  in
wholesale brokerage and professional liability programs.

         Subsidiaries of Aon Consulting and the European benefits  operations of
Aon Holdings serve the employee  benefit needs of clients around the world.  Aon
Consulting is one of the world's largest  integrated human resources  consulting
organizations.  Focusing on the increasing demand for outsourcing solutions, Aon
Consulting  targets emerging  businesses,  IPOs, recent mergers and acquisitions
and corporations that are reengineering staff functions.

         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.  Aon Consulting,  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.  Aon  Consulting
subsidiaries offer services to clients including  organizational analysis and HR
strategic  planning,  recruitment and selection,  benefits design and management
training and development. Benefits issues in foreign countries are becoming more
complicated, and Aon Holdings and Aon Consulting anticipate increased demand for
their  services  in these  markets.  In  particular,  the 1997  acquisitions  of
Sodarcan  Inc.  and  Martineau  Provencher  &  Associates  will  strengthen  the
Registrant's consulting expertise in Quebec.

         Aon's reinsurance brokerage activities are organized under Aon Re. With
the  acquisitions  of A&A  and  Bain  Hogg,  Aon Re is a  global  leader  in the
reinsurance  and specialist  brokerage  industry.  Aon Re serves the alternative
market with reinsurance placement, alternative risk services, captive management
services and catastrophe information forecasting.

         AGL  is  a  London-based  Lloyd's  broker  that  places  wholesale  and
reinsurance  business  in the London and  international  markets  and serves the
needs of a wide range of clients around the world.

(2)  INSURANCE UNDERWRITING

         Combined Insurance Company of America ("Combined Insurance");  Combined
Life Insurance  Company of New York  ("CLICNY");  Virginia Surety Company,  Inc.
("VSC");  London General Insurance Company Limited ("London  General");  and Aon
Warranty Group, Inc. ("Aon Warranty").

         The  Registrant's  insurance  underwriting  subsidiaries  are part of a
highly competitive  industry that serves individual  consumers in North America,
Europe, Latin America and the Pacific by providing accident and health coverage,
traditional life insurance,  and extended warranties through global distribution
networks most of which are directly owned by the Registrant's subsidiaries.

         The  life,  accident  and  health   distribution   network  encompasses
primarily  the  agents  of  Combined   Insurance  and  CLICNY  (which   operates
exclusively   in  the  State  of  New  York).   With  more  than  five   million
policyholders, Combined Insurance has more individual accident policies in force
than any other United  States  company.  Combined  Insurance,  the  Registrant's
principal life, accident and health insurer, has a direct sales force of several
thousand  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  coverage  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  obligations,  thereby not subject to
escalating medical costs.  Combined  Insurance offers a simplified  accident and
sickness long-term  disability policy. In addition to its traditional  business,
Combined  Insurance  is  expanding  its  product  distribution  through  payroll
deduction, worksite marketing programs.

         Combined Insurance and CLICNY market whole life products through direct
sales career agents in the United States.  Combined  Insurance  ranked among the
top 140 life  insurance  companies  in the United  States in terms of total life
premiums in 1996. Life insurance  business is conducted by the Registrant's life
insurance subsidiaries in the United States, Canada, Europe and Asia Pacific.

         The Registrant's  extended warranty and specialty  insurance  business,
conducted by subsidiaries VSC in North America and London General in Europe,  is
composed  primarily  of  extended  warranty  insurance  products,   professional
liability  insurance  coverages,  workers'  compensation and specialty financial
institution coverages.  VSC and London General continue to be one of the world's
largest  underwriters of consumer extended  warranties.  The automobile warranty
products are sold in the United States,  Canada,  the United  Kingdom,  Ireland,
France,  The Netherlands,  Belgium,  Spain and Japan. Aon Warranty Group handles
the  administration  of  certain  extended  warranty  products  on  automobiles,
electronic goods,  personal computers and appliances.  It serves  manufacturers,
distributors  and retailers of major  worldwide  consumer  product and financial
institutions, associations and affinity groups in North America and in Europe.

(3)  DISCONTINUED OPERATIONS

         The Life Insurance  Company of Virginia ("LOV") and Union Fidelity Life
Insurance Company ("UFLIC").

         In April 1996,  the  Registrant  and Combined  Insurance  completed the
sales of Combined Insurance's subsidiaries,  LOV and UFLIC. The business written
by LOV  primarily  included  capital  accumulation  products and some other life
products.  UFLIC operated in the United States in the highly  competitive direct
response  life and health  marketing  segment of the  industry.  The  Registrant
hereby  incorporates by reference note 3 of the Notes to Consolidated  Financial
Statements on page 32 of the Annual Report.

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 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  continue  to 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 is not expected to have any significant
impact on the insurance business of the Registrant.

         Several years ago, the NAIC 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 a  company's
business.  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.

                                     - 5 -
<PAGE>
         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,  the 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
protection  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 Aon 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 or  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, Aon Group subsidiaries have
arrangements with residents or business entities licensed to act in the state.

         In  1996  the   federal   Health   Care   Insurance   Portability   and
Accountability Act of 1996 ("HIPPA") was enacted. The Act requires the states to
take action to implement  the  requirements  of the Act or to become  subject to
federal  oversight.  HIPPA  implementation  by the  states  has  not  materially
affected  the business of the  Registrant's  subsidiaries.  In addition,  recent
federal laws and proposals,  mandating  specific  practices by medical insurers,
and the health care industry will not,  because of the nature of the business of
the Registrant's subsidiaries, materially affect the Registrant. 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  federal and state health care changes,  the Registrant
does not expect a major  impact on its  operations  because of the  supplemental
nature of most of the policies issued by its insurance  subsidiaries and because
the coverages are primarily  purchased to provide,  on a fixed-indemnity  basis,
protection against  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 insurance
underwriting  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.


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 had approximately 40,000 employees at the
end of 1997 of whom  approximately  35,000 are salaried and hourly employees and
the remaining  5,000 are sales  representatives  who are  generally  compensated
wholly or primarily by commission.


ITEM 2.  PROPERTIES.

         The Registrant's  subsidiaries own and occupy office buildings in seven
states 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.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS


(1)    See notes to consolidated financial statements  incorporated by reference
       from the Annual Report.


(2)    Payments made as  assessments  by state guaranty funds to cover losses to
       policyholders of insurance companies under regulatory supervision for the
       years ended  December 31,  1997,  1996 and 1995 were $0.8  million,  $1.4
       million and $5.0 million,  respectively.  


(3)    Generally,  the net assets of Aon's insurance  subsidiaries available for
       transfer  to the  parent  company  are  limited to the  amounts  that the
       insurance  subsidiaries'  statutory net assets exceed  minimum  statutory
       capital  requirements;  however,  payments of the amounts as dividends in
       excess  of  $360  million  may  be  subject  to  approval  by  regulatory
       authorities.


(4)    Subsequent Events
       On  February  5, 1998,  Aon  announced  an  agreement  to  acquire  Gil y
       Carvajal, the leading broker in Spain. In  addition, Aon announced an
       agreement in principle to acquire  Le Blanc de Nicolay, subject to normal
       regulatory consents and due diligence. Le Blanc de Nicolay is the largest
       reinsurance  broker in  France  and is also prominent in retail brokerage
       and  consulting  services.    Annual  revenues  of these acquisitions are
       approximately $125 million.

                              EMPLOYMENT AGREEMENT

         This  Employment   Agreement  dated  as  of  June  1,  1993  among  Aon
Corporation,  a Delaware corporation ("Aon"), Aon's wholly-owned subsidiary, Aon
Risk  Services,  Inc.,  a Delaware  corporation  ("Aon  Risk"),  and  Michael D.
O'Halleran ("O'Halleran").

         WHEREAS, pursuant to an Employment Agreement dated as of April 15, 1988
(the  "Prior  Agreement"),  O'Halleran  has been  Chairman  and Chief  Executive
Officer of Aon Risk, and has served as a director and/or officer of subsidiaries
of Aon Risk; and

         WHEREAS,  while  the term of the  Prior  Agreement  does not end  until
November 1, 1997, the parties to the Prior  Agreement and this Agreement  desire
to continue the services of O'Halleran  beyond  November 1, 1997 and provide for
new terms and conditions governing O'Halleran's employment by Aon Risk.

         NOW,  THEREFORE,  in  consideration  of the mutual  covenant  contained
herein and other good and valuable consideration, the receipt and sufficiency of
which is hereby acknowledged, the parties hereto agree as follows:

                         ARTICLE I: Scope of Employment

         1.1 TERM.  O'Halleran will continue to be an employee of one or more of
Aon's  subsidiaries for a term ending on December 31, 1998 (the "Initial Term").
The term of  O'Halleran's  employment  will be subject to automatic  renewal for
successive  twelve-month  periods thereafter unless this Agreement is terminated
by O'Halleran or the Aon subsidiary by which he is then principally  employed as
of the  expiration of any such  twelve-month  period upon not less than 30 days'
prior written notice to the other party.

<PAGE>
         1.2  DUTIES.  Aon  Risk  has  caused  O'Halleran  to  be  elected,  and
O'Halleran agrees to serve, as Chairman,  Chief executive officer and a director
of Aon Risk. O'Halleran will report directly to Aon Risk's board of directors.

         1.3 BOARD REPRESENTATION.  While Aon, Aon Risk and O'Halleran recognize
that the  right to elect  directors  is by law  vested  in  stockholders,  it is
nevertheless  mutually  contemplated,  subject to such  right,  that  during the
entire time that  O'Halleran  is  principally  employed by Aon Risk,  O'Halleran
shall  continue  to serve as a director  of Aon Risk;  provided,  however,  that
O'Halleran's  removal from Aon Risk's  board of directors  shall not be deemed a
breach of this Agreement.

         1.4 EXCLUSIVE  EMPLOYMENT.  So long as O'Halleran is an employee of any
of Aon's  subsidiaries,  O'Halleran  (i) will devote his best efforts and all of
his business  time,  efforts,  and attention to furthering the interests of such
subsidiaries;  and (ii) will not, directly or indirectly, engage in any business
activity  which is  competitive  with any  business  activity  conducted by such
subsidiaries.

         1.5 NO VIOLATION OF COVENANTS AND  RESTRICTIONS.  O'Halleran agrees not
to violate any legally enforceable covenants or restrictions  affecting his work
for any of Aon's subsidiaries,  as set forth in any agreements into which he may
have  entered,  including,  but not limited  to,  employment  agreements,  sales
agreements,  deferred  compensation  agreements,   restricted  stock  or  option
agreements.   O'Halleran   will  not  act  in  any  capacity  as  a  reinsurance
intermediary  that would  violate  any  then-legally  enforceable  covenants  or
restrictions affecting his work.

         1.6 REPRESENTATION  REGARDING PRIOR EMPLOYMENT.  O'Halleran  represents
and warrants to Aon that he has provided  Aon with copies of all  covenants  and
restrictions  which may be applicable to his  employment  hereunder and that all
such covenants and restrictions are accurately  identified in Exhibit A attached
to this Agreement.

                                     - 2 -
<PAGE>
         1.7 TERMINATION. O'Halleran's employment with any of Aon's subsidiaries
may be terminated at any time by the Aon subsidiary by which  O'Halleran is then
principally  employed in the event of  O'Halleran's  dishonesty as determined by
the  Compensation  Committee  of Aon's Board of Directors  ("Dishonesty").  Such
termination  is  hereinafter  referred  to as a  "Termination  for  Dishonesty."
O'Halleran's  employment  with any Aon  subsidiary may also be terminated at any
time  for  any or no  reason  by  O'Halleran  or the  Aon  Subsidiary  by  which
O'Halleran is then  principally  employed,  upon 10 days' prior  written  notice
given by O'Halleran to such Aon subsidiary ("Voluntary Termination") or given by
such Aon subsidiary to O'Halleran ("Involuntary Termination").

                            ARTICLE II: Compensation

         2.1 BASE COMPENSATION. From the date of this Agreement until January 1,
1994,  O'Halleran's  base salary shall  continue at its' current rate per annum.
Thereafter,  O'Halleran's base salary shall be determined  annually by the Board
of Directors of the Aon subsidiary by which he is then principally employed, but
shall be at a rate not less than $750,000 per year,  and shall be subject to the
approval  of the  Compensation  Committee  of the  Board  of  Directors  of Aon.
O'Halleran's  base  compensation  shall be  payable on the same dates and in the
same  manner  as the  base  compensation  of  senior  executives  of  other  Aon
subsidiaries.

         2.2 EXECUTIVE BENEFITS.  Subject to the terms of such plans and so long
as O'Halleran remains employed by any of Aon's subsidiaries,  O'Halleran will be
covered  under  all  retirement,   employee  investment,   medical  and  dental,
short-term and long-term  disability,  life  insurance,  accident  insurance and
other similar benefit plans  substantially  equivalent to such plans  maintained
from time to time by Aon's  subsidiary,  Rollins Hudig Hall Group,  Inc. for its
senior executives.  If any such plan bases payments  thereunder on the amount of
O'Halleran's  compensation,  his  

                                     - 3 -
<PAGE>
compensation  for  purposes  of such  plan  shall,  unless  such  plan  provides
otherwise,  be deemed to be his base  compensation  as  determined  pursuant  to
Section 2.1 of this Agreement.

         2.3 PAYMENTS IN THE EVENT OF INVOLUNTARY  TERMINATION.  In the event of
O'Halleran's  Involuntary  Termination  before  December 31, 1998 and so long as
O'Halleran  continues to satisfy his  obligations  under Sections 3.2 and 3.3 of
this  Agreement,  he will be paid  compensation at the rate of $750,000 per year
for the period following such Involuntary Termination (in addition to any amount
which may be  payable  pursuant  to  Section  2.7 of this  Agreement)  until (i)
December  31,  1998,  or  (ii)  the  expiration  of  two  years  following  such
Involuntary Termination, whichever is longer.

         In addition,  if this  Agreement is not renewed in accordance  with the
provisions  of Section 1.1 of this  Agreement  after  December  31, 1998 (unless
sooner terminated in which case the provisions of the preceding sentence of this
section shall only apply),  O'Halleran will be paid  compensation at the rate of
$750,000 per year for the two years following December 31, 1998.

         2.4  LOANS.  O'Halleran  currently  owes Aon  $300,000  pursuant  to an
unsecured  promissory  note (the "Note") which bears  interest at the rate of 8%
per annum,  without  compounding.  The principal amount and all accrued interest
under such Note will become due and payable in full on the second anniversary of
such  Note;  provided,  however,  that,  as  additional  consideration  for  the
performance  of services by  O'Halleran,  all  principal  and  interest  due and
payable on the Note will be forgiven  (x) if  O'Halleran  remains an employee of
any of Aon's subsidiaries until the date such amounts would otherwise become due
and payable on such Note or (y) as provided in Section 2.7.

         2.5 RESTRICTED STOCK. Pursuant to the provisions of the Aon Stock Award
Plan (the "Plan") Aon will cause to be granted to  O'Halleran  Aon common stock,
par value $1.00 per share ("Aon  Stock") in the following  amounts  effective on
the dates set forth opposite such amounts:

         (c)      20,000   January 1, 1998

         Each of (a),  (b), and (c) above shall be  considered  separate  grants
under the Plan,  and shall be  subject  to all the terms and  conditions  of the
Plan. Each of the grants outlined  hereinabove shall be adjusted  accordingly in
the event Aon Stock is subject to split,  stock  dividend,  recapitalization  or
exchange.  Notwithstanding  anything to the contrary herein, should O'Halleran's
employment  terminate  hereunder for any reason,  no  subsequent  grant shall be
effective.

         2.6  CLUB  MEMBERSHIPS.  Aon  will pay all  initiation  fees,  periodic
membership  dues  and  reasonable  client  entertainment  expenses  incurred  by
O'Halleran at the Big Foot Country Club, the Royal  Melbourne  Country Club, the
Tower  Club  and  the  Tavern  Club  during  his  employment  by  any  of  Aon's
subsidiaries pursuant to this Agreement.

         2.7 ADDITIONAL  COMPENSATION  UPON DEATH,  EXTENDED TOTAL DISABILITY OR
INVOLUNTARY  TERMINATION.  During the Initial Term, within 30 days after (i) the
first date on which O'Halleran has continuously  been Totally Disabled  (defined
and  determined in a manner  consistent  with the long-term  disability  plan or
plans under which  O'Halleran  is covered  pursuant to Section 2.2) for at least
one year,  (ii) the date of  O'Halleran's  death while  employed by any of Aon's
subsidiaries or (iii) the date of O'Halleran's Involuntary Termination (any such
date, the "Payment Date"),  (a) O'Halleran or the executors or administrators of
his  estate,  as the case may be,  shall  receive  a  payment  equal to the base
compensation set forth in Section 2.1, (b) the principal of and accrued interest
on all  Notes  made  pursuant  to  Section  2.4 shall be  forgiven,  and (c) the
unvested  portion  of any grant  made  pursuant  to  Section  2.5  herein  shall
accelerate and become fully vested.

                ARTICLE III: CONFIDENTIALITY AND NON-COMPETITION

         3.1 ACCESS TO INFORMATION. As an employee and officer of one or more of
Aon's subsidiaries, O'Halleran acknowledges that he is expected to obtain access
to  proprietary,  secret or confidential  information  relating to (i) business,
conduct or operations of such  subsidiaries  and their  clients,  (ii) research,
processes,   methods,  techniques,   computer  programs,  client  lists,  client
requirements,  reports  and  similar  materials  used in  connection  with  such
subsidiaries'  business,  and (iii) the  enhancement  of,  or  possible  uses or
applications for, such items or services.

         3.2 CONFIDENTIALITY.  While O'Halleran is an employee or officer of any
subsidiary  of Aon  and at all  times  thereafter,  he  agrees  to  respect  the
confidentiality of any information  received as a result of his association with
any  subsidiary  of Aon and agrees not to  disclose  to others any  proprietary,
secret or confidential information.  Upon termination of O'Halleran's employment
for any reason,  he agrees not to take any  confidential,  proprietary or secret
information or copies  thereof with him, nor will he use,  duplicate or disclose
such information to anyone else.

         3.3 NON-SOLICITATION.  In light of the special and unique nature of the
relationship described herein, as consideration for O'Halleran's  employment and
in order to protect the legitimate and protectible business interest of Aon Risk
and Aon Risk's subsidiaries, including, but not limited to, any confidential and
proprietary  information  to which  O'Halleran  will obtain  access,  O'Halleran
agrees that for a period of two years  following  Voluntary  Termination  of his
employment,  Termination  for  Dishonesty or other  expiration of his employment
under this Agreement, O'Halleran will not directly or indirectly:
         (a) solicit business from, or assist others in soliciting business from
or  performing  work for, any client of Aon Risk or any  subsidiary  of Aon Risk
which O'Halleran  personally handled or 

                                     - 6 -
<PAGE>
serviced  at  any  time  during  the  one  year  period  immediately   preceding
termination; or

         (b)  attempt  to hire,  hire,  assist in hiring or cause to be hired by
another,  any person who was an  employee of Aon Risk or any  subsidiary  of Aon
Risk at any time during the six months preceding termination.

         3.4 IRREPARABLE INJURY.  O'Halleran expressly acknowledges,  recognizes
and understands that a breach of any of the provisions of Section 3.2 or Section
3.3  will  cause  irreparable  damage  to the  business  of one or more of Aon's
subsidiaries  and that such damage will be difficult or  impossible  to measure.
O'Halleran agrees that in the event of any such breach, any Aon subsidiary which
may be injured thereby,  in addition to such other rights and remedies as it may
have, may apply to any court of competent  jurisdiction  for an order  requiring
specific  performance  of the  provisions  of  Section  3.2  and  3.3  and  seek
temporary,  preliminary  and permanent  injunction  relief against any act which
would violate any such provision. If any provision of Section 3.2 or Section 3.3

construed  a  restricting  the  activities  of  O'Halleran  to the  extent  such
activities may be lawfully restricted.

         3.5 O'HALLERAN'S ACKNOWLEDGEMENT.  O'Halleran understands and expressly
acknowledges  that each of the foregoing  provisions is reasonable and necessary
to protect and preserve the  legitimate  and  protectible  business  interest of
Aon's  subsidiaries,  and the economic benefit derived therefrom,  and that such
restrictions will not prevent O'Halleran from earning a livelihood in his chosen
business and are not an undue restraint on him.

         3.6  SURVIVAL.  The  provisions  of this Article III shall  survive any
termination of this Agreement.

                            ARTICLE IV: Miscellaneous

         4.1 AON  GUARANTEE.  Aon  guarantees  the payment of its  subsidiaries'
obligations to O'Halleran hereunder.

         4.2 EXPENSES.  Aon will reimburse  O'Halleran for all fees and expenses
of legal counsel and accountants  reasonably  incurred by him in connection with
the  negotiation of this  Agreement.  As O'Halleran will comply with any legally
enforceable  covenants and restrictions  applicable to his employment hereunder,
it  is  unlikely  that  litigation  will  arise  regarding  such  covenants  and
restrictions.  However,  in the unlikely  event that an action is filed  against
O'Halleran,  Aon  will  indemnify  him and hold  him  harmless  for the fees and
expenses  of legal  counsel  selected by Aon  subject to  O'Halleran's  approval
(which approval shall not unreasonably be withheld) for the defense of any claim
by any of his  present  or  former  employers  which is based  primarily  on his
alleged violation of the covenants and restrictions identified on Exhibit A.

         4.3 GOVERNING  LAW. This agreement will be governed by and construed in
accordance with the laws of the State of Illinois.

         4.4  NOTICES.  Any notice  required or permitted to be given under this
Agreement  shall be sufficient  if in writing and sent by certified  mail to his
residence  address as it appears on Aon's records in the case of O'Halleran,  or
to  Aon's  principal  office  in the  case  of  Aon or any of its  subsidiaries,
addressed to the Secretary of Aon.

         4.5  SUCCESSORS AND ASSIGNS.  This Agreement  shall be binding upon and
inure to the  benefit  of Aon and its  successors  and  assigns,  including  any
successor  by merger,  consolidation  or  transfer of  substantially  all of the
assets of Aon. Such successor shall assume its  performance,  and shall have the
same duties and  obligations  as Aon. This  Agreement  shall be binding upon and
inure to the benefit of O'Halleran  and his heirs and personal  representatives;
provided,  however,  that  O'Halleran  shall make no  assignment of any right or
benefit hereunder, except as authorized by

specific provision hereof.

         4.6  SEVERABILITY.  If for any reason any  provision of this  Agreement
shall be held invalid in whole or in part, such invalidity shall not affect such
provision to the extent not so held  invalid,  or any other  provisions  of this
Agreement not so held invalid,  and such provision and all other such provisions
shall to the full extent consistent with law continue in full force and effect.

         4.7 ENTIRE AGREEMENT.  This Agreement  contains the entire agreement of
the parties and supersedes all prior  agreements or  understandings  between the
parties,  including without  limitation the Prior Agreement.  This Agreement may
not be changed orally,  but only by an instrument in writing signed by the party
against  whom  enforcement  of any waiver,  change,  modification,  extension or
discharge is sought.

and  implementation of risk transfer  programs.  We offer traditional treaty and
facultative  reinsurance  placement  services as well as capital market products
and sophisticated risk portfolio analysis.

HIGHLIGHTS  During 1997,  ARW expanded its global  reinsurance  network  through
organic  growth and  strategic  acquisitions.  We  enhanced  our North  American
presence by adding  offices in Canada and the  southeastern  United  States.  We
deepened our penetration in Europe,  Australia,  Canada,  Asia and Latin America
through Aon Group Limited,  which brought  together the collective  expertise of
the Alexander  Howden  Group,  Bain Hogg,  Jauch & Hubener,  the Minet Group and
Nicholson Jenner Leslie.

We continued to strengthen our position as a leader in developing capital market
and  risk  transfer   innovations.   For  example,   we  placed  three  CatEPuts
(Catastrophe  Equity  Put  programs)  for  clients.  And,  we worked  with newly
launched  Aon  Capital  Markets to  enhance  our  ability  to assist  clients in
managing their risks on a comprehensive basis.

OUTLOOK  The global  reinsurance  market is  undergoing  significant  changes as
consolidation occurs in all sectors. ARW is at the forefront of the industry and
continues to look for  opportunities  to extend its global  reach.  We also will
continue to make significant  investments in technology and value-added services
in order to provide the most  comprehensive  risk management  services.  We will
further  strengthen  our  global  reinsurance  network  to ensure  that the most
advanced  products  and services  are  available to Aon clients  anywhere in the

Look up the definition of global  business and you should find the name Sara Lee
Corporation. This $20 billion company is one of Aon's most prominent clients and
one that really brings out the best in our global  network,  which now stretches
across 550 offices and more than 100 countries.

As Sara Lee's primary insurance broker, everything Aon does for them must have a
global reach. "We manage global risks, global resources,  global  commu-nication
systems," says Carol Murphy, Strategic Account Manager of the Aon/Sara Lee team.
"And, we deliver on a local level,  supplying local risk management  needs  in a
program coordinated  globally." All of Aon's offices are  electronically  linked
via several  proprietary  computer systems,  providing  up-to-the-minute  client
information.

"With operations in more than 40 countries and a global distribution system that
enables us to market branded  consumer  products in more than 140 countries,  we
rely on solid  partnerships to support our broad global  presence," says Vincent
Coffey, Sara Lee Corporation's Director, Risk Management.  "Aon has put together
a team that meets our needs in virtually every corner of the world.  With 42% of
our sales now coming from  business  conducted  outside the U.S.,  Aon has grown
with us to support our risk management needs worldwide."

In the Chicago  office,  20 of our risk  specialists  are  dedicated to Sara Lee
while more than 100 others are strate-gically  located around the world. "We use
our global network to help Sara Lee achieve its global growth  strategies," adds
Carol.  "For  instance,  we were  part  of the  planning  team  for  Sara  Lee's
integration of Aoste, a French acquisition with $800 million in revenues. We had
to make sure that in addition to providing the best local insurance service,  we
were in sync with the company's global standards and objectives."

Sara Lee also benefits from Aon's Strategic Account  Management (SAM) initiative
designed to build stronger  partnerships  with its major  clients.  The SAM team
responsible for Sara Lee deeply  understands its business,  its expectations and
its goals.  As a result,  Aon has been able to help Sara Lee strengthen the risk
management synergy between its U.S. and European businesses as well as help with
recent  divestitures  as Sara Lee  focuses on  building  leadership  brands on a
global basis.

"Aon people know our business,  act with a sense of urgency,  know where to find
solutions in the global  marketplace and, above all, have great integrity," adds
Vince,  who has worked with Aon since 1989.  "We share a philosophy of business.
Aon believes in a collaborative partnership and progressive business management.
That's the way we like to do business."

Aon Services Group 

Aon Services Group (ASG) designs and delivers  specialized  retail and wholesale
insurance  products and services for associations  and affinity groups,  service
businesses,  insurance  companies,  independent  insurance  agents and  brokers,
governments,  health care  providers and commercial  organizations.  Through its
subsidiaries,  ASG provides wholesale brokerage capabilities, as well as program
administration  and claims  management  expertise for  insurance  organizations.
ASG's thorough  knowledge of targeted  industries and market segments,  together
with  leading-edge  products  and  multiple-channel  distribution  systems,  has
produced   recognized   experts  in  program   administration  for  professional
liability,  with specialized expertise in the accounting,  health care and legal
professions.

HIGHLIGHTS In 1997, Aon Services Group changed its name from Aon Specialty Group
to reflect  the fact that it  provides  not only  highly  specialized  insurance
products but many comprehensive,  value-added  services as well. We concentrated
our efforts on  consolidating  existing ASG units and  assimilating  several key
acquisitions.  We integrated Alexander Howden North America and Swett & Crawford
into ASG's wholesale  brokerage unit, merged Alexander & Alexander's health care
practice unit with the Aon  Healthcare  Alliance,  and added segments of several
other acquisitions into our Affinity Insurance Services unit.

OUTLOOK ASG has a solid  position as a premier  provider of wholesale  brokerage
services.  Additional  resources have  strengthened  Aon  Healthcare  Alliance's
ability to offer a wide array of products  and  services to all  segments of the
health care industry.  We are increasing our efforts to distribute  insurance to
affinity groups in Europe,  Latin America and other global markets.  We also are
developing our reputation and expertise in third-party claims administration. In
order to offer more  products and  services to more  clients,  we are  enhancing
existing distribution networks and promoting greater  interdependence with other
Aon units.

Aon Services  Group  consists of several  highly  focused  specialty  companies,
providing industry-specific  expertise, unique insurance coverages and wholesale
brokerage services.

Aon Services Group in brief: 

   o  A premier direct  marketer of specialty  coverages to affinity  groups and
      associations

   o  A leading provider of products,  services,  resources and expertise to the
      health care industry

   o  The largest U.S. wholesale insurance brokerage operation

   o  A rapidly growing third-party claims administration organization

   o  A leading provider of comprehensive  underwriting  management programs for
      various industries,  including financial services,  media,  entertainment,
      sports and leisure and government entities

   o  Our Affinity  Insurance Services produces $1 billion in premiums from more
      than 5 million policyholders

At Aon, our concept of teamwork is called "interdependence," meaning two or more
companies working together for the benefit of a client. In bringing together the
best of Aon,  we believe  our  culture  of  interdependent,  innovative  problem
solving clearly distinguishes our service from the competition.

By breaking down barriers that often exist between brokerage  specialties,  Aon
professionals  can  pool the best  expertise  and  resources  to provide a full 
range of  solutions.  Working as an integrated,  networked  global team, we can
meet  our  clients'  risk  management,  risk  transfer  and   consulting  needs 
anywhere in the world. 

A good example is our developing  partnership with Philips Electronics N.V., the
Dutch  company  of more  than 100  businesses  ranging  from  lighting,  medical
products,  electronics  and  consumer  products to film and music.  Aon has been
managing most of Philips' risk exposures since 1996 when Philips  remarketed its
insurance  programs.  Soft  market  pricing  and  Aon's  expanded  service  base
convinced  the  company  to  rethink  its  traditional  internal   captive-based
insurance programs and turn to Aon.

"When Philips restructured its risk management operations, Aon was ready to step
in," says Kik Thole,  Strategic  Account Manager.  "We are able to bring all the
resources of Aon together and deliver them to Philips seamlessly."

Philips Risk Manager Arjen Ronner explains,  "Risk management  reengineering  is
an ongoing process, involving  both strategy and implementation.  Aon is able to
assist our local managers with many of the administrative tasks so that they can
focus their efforts on the critical risk management issues."

For Philips'  diverse  businesses,  Aon  developed a  comprehensive  multi-line,
multi-year  program,  which is managed  out of Holland and  supported  by global
practices  in New York and  London.  Most  recently,  our Hong Kong  office  was
instrumental  in  securing   insurance  coverage  for  Philips'  joint  ventures
throughout China.

"We need an experienced, competent team of marketing and technical specialists,"
adds  Arjen  Ronner.  "Our  Aon  account  team in  Rotterdam  is able to  access
resources from around the world and deliver them to our door."

HIGHLIGHTS  During 1997, ACW solidified its position in several key markets.  In

management,  the  outsourcing  trend is growing and the demand is strong for our
services.  We are seeing significant gains in the middle market, where companies
are finding our outsourcing services to be very cost effective.  ACW is a leader
in innovative retirement plan consulting and creative  compensation  strategies.
To help clients manage these  activities,  we work in conjunction  with Aon Risk
Services  to offer a full  package  of  services  in risk  management,  employee
benefits,  compensation,  human  resources and change  management.  

OUTLOOK In a marketplace  where many  companies  offer  various human  resources
consulting  services,  ACW is  growing  and  distinguishing  itself  as a  fully

The business of risk management demands innovative solutions, teamwork, in-depth
industry  knowledge and absolute client focus. Aon has become a global leader in
risk management because it has been able to attract, retain and develop the best
people with the best skills in the industry.

Because  of our depth of talent  and  expertise,  we've  been able to  establish
long-term  relationships  with the world's top businesses.  Our 40,000 employees
worldwide  share  goals  aligned  with the  interests  of our  clients and other
stakeholders.  A good example is our relationship with Tomkins PLC, a $7 billion
multinational  company.  Managing  risk for  Tomkins'  more  than 100  different
businesses is a totally engaging responsibility for Aon risk management experts.

"We have some of the  industry's  best people  working on the Tomkins  account,"
explains Charlie Miller,  Strategic  Account  Director in Cincinnati,  Ohio, the
U.S. hub office for Aon's Tomkins service team.

"We always give them a very high level of customer service."

London-based  Tomkins produces everything from Murray lawn mowers in the U.S. to
Ranks Hovis McDougall food products in the U.K. Aon's  accomplished team of risk
and  liability  specialists  is  involved in the  administration  of the Tomkins
account,  providing needs assessment,  strategic planning and project management
as a platform for the day-to-day service delivery.

"Risk management is an expertise we outsource," says Richard  Marchant,  Tomkins
Administration Director and Company Secretary. "We look to our colleagues at Aon
for the expertise and  knowledge we need. We work with  individuals  we rely on.
That's what makes this relationship work so well."

To fully serve the needs of Tomkins and its many businesses worldwide,  the team
uses a combination of Anistics Omega,  Aon's  comprehensive  database of claims,
exposure, policy, premium allocation and property information, along with e-mail
and document management systems, all tailored to Tomkins' needs. Together, these
give Tomkins and Aon instant access to quality risk management information.

"We couldn't  manage the extensive  needs of a diverse global company  without a
comprehensive  database  and  fast,  reliable  communications,"  explains  Julia
Harrop,  Worldwide  Account  Director,  and  head  of the  Aon-Tomkins  team  in
Shrewsbury,  England. "This is a complex account that requires careful selection
of appropriate resources for the many different businesses we serve."

From  Tomkins'  point of view,  working with the Aon team means working with the
best.  "As far as I'm  concerned,  Aon is the number one  broker,"  adds Richard
Marchant. "They have the resources and the expertise we need for the future."

Virginia Surety Company and London General Insurance Company

Virginia Surety Company (VSC) and its sister company,  London General  Insurance
Company (LGI),  provide  innovative  insurance  programs as well as underwriting
expertise for a variety of traditional and  non-traditional  insurance programs.
Their   expertise  and   capabilities  in  consumer   extended   warranties  are
unsurpassed.

In addition,  Aon Warranty Group (AWG) offers a range of fee-based services that
include  premium  administration,  claim  processing,  information  systems  and
accounting  support,  customer  service,  customer care management,  value-added
after-sale products, training and profit management services.

Our distribution  channels include auto dealerships,  manufacturers,  retailers,
distributors,  financial  institutions,  direct  mail,  telemarketing,  affinity
groups, associations and the Internet.

HIGHLIGHTS  During  1997,  we  maintained  our  position as the world's  largest
independent provider and administrator of warranties for consumer  products such
as automotive,  consumer  electronics  and  appliances,  personal  computers and
homes. We're experiencing significant growth in our specialty insurance products
for  credit  card  enhancement  programs,  cellular  phones,  power  sports  and
involuntary unemployment.

Through  new  operations  in  Argentina,  Australia,  Brazil and  Japan,  AWG is
creating new business opportunities and strengthening Aon's global development.

In April,  AWG  acquired  Innovative  Services  International  and  expanded its
offerings to include a new Customer Care Management program, a fast-growing call
center service that enhances our core products.

OUTLOOK Through operations on five continents, VSC, LGI and AWG will continue to
expand their reach,  product  offerings  and  distribution  systems into new and
existing  markets.  As we expand,  we expect our fastest  growing  business will
continue to be our warranty  operations.  We'll build our consumer care services
by providing  customer  service,  technical  support and claims  services for an
ever-growing list of retailers and consumer brand marketers.

Virginia Surety and its sister companies offer  comprehensive  consumer extended
warranty and consumer service programs.

Virginia Surety in brief:

   o  VSC is rated A+ by A. M. Best

   o  VSC/LGI  is  the  world's  largest  independent  underwriter  of  extended
      warranties

   o  More than 4 million policies issued in 1997

Aon  Warranty  Group in brief:  

   o  One of the largest  independent  service  contract  administrators  in the
      world

   o  Call centers average 183,000 service calls daily

Imagine  dealing with more than 180,000  phone calls daily.  And, for each call,
you have a smile in your voice and an answer at the ready.  That's just what the
customer  service  representatives  at Aon Warranty  Group and  Virginia  Surety
Company are doing every day for their manufacturing and retail clients.

A comprehensive  operation of three independent call centers, Aon's new customer
care service is being  provided as an added-value  service to our clients.  It's
just one of the new opportunities Aon has developed to serve customers' evolving
needs.  For example,  when consumers  call the local store of a national  retail
chain,  the  phone  line  connects  to an  Aon  call  center.  The  call  center
representative can pull up all the vital information about that particular store
on his or her PC  screen  and  can  give a quick  and  efficient  response.  The
consumer is satisfied and the retailer  doesn't have to employ in-store staff to
handle phone inquiries.

In addition to this rapidly growing service, three other Aon call centers in the
U.S.  answer  claim  center  calls  for auto,  home,  appliance  and  electronic
warranties  as  well  as  24-hour-a-day  technical  service  support  calls  for
manufacturers of computers and other consumer products.

And every caller gets an answer. While handling calls for a leading manufacturer
of consumer brand clothing,  Aon's customer service was able to find one thrifty
caller the right button to match his 40-year-old pair of blue jeans.

From risk management, loss control and claims management to added-value services
such as extended product warranties  and customer service programs, Aon provides
the services and products that serve the spectrum of client needs.

For example, we underwrite and administer service contracts for  household names
across America and around the globe, including Office Depot, the world's largest
office products retailer, operating over 600 retail stores.

"When we looked for the ideal  partner to help us develop our  service  contract
business, the clear choice was Aon Warranty Group," says Julie Siderfin,  Office
Depot's Manager of Service Contract Sales.

Aon Warranty  Group has served  Office Depot for several  years.  "In that time,
we've seen service  contract sales rise  dramatically,"  she adds.  "And, in the
months and years ahead, we're looking forward to expanding our relationship with
Aon Warranty Group."

Combined Insurance Company of America

Serving the needs of both individuals and businesses, Combined Insurance Company
of America  (CICA) is a leading  distributor  and  underwriter  of  supplemental
insurance policies, including life, health, accident and disability income.

Many of CICA's nearly 5 million insureds are self-employed or work in firms with
modest employee benefits.  CICA's competitively priced policies help the insured
supplement their employer-provided benefit plans to maintain financial stability
in a time of need. We offer a full range of supplemental insurance products with
additional  services for the worksite,  including  voluntary benefit  enrollment
administration and preparation of benefit statements.

HIGHLIGHTS  During 1997,  CICA took steps to develop new markets and  strengthen
existing lines. For our traditional  product lines, we introduced higher benefit
accident  policies with  convenient  monthly  payment  options.  We aggressively
pursued our target market with an array of new worksite  products -- all capable
of  being  customized  to the  individual  employee  and  paid  through  payroll
deduction.  We introduced  administrative  services  specifically  designed  for
small employers to enhance the value of their benefit  programs.  In addition to
offering these products  directly into the market,  CICA is working closely with
Aon Risk  Services  retail  brokers to introduce  CICA  services to existing ARS
clients.

OUTLOOK CICA will continue  expanding its product  lines,  its customer base and
its  geographic  presence.  As baby boomers age, the senior market  represents a
significant  opportunity  and CICA is  launching a  comprehensive  portfolio  of
insurance  products  aimed at the  growing  senior  population,  including a new
long-term care policy. Internationally, CICA is expanding its worksite marketing
in the United  Kingdom and Latin America.  In its  traditional  market,  CICA is
introducing  improved  products attuned to market needs with affordable  payment
options.  CICA will  continue  its  tradition of selling to  individuals  in the
workplace by using  enhanced  products,  payroll  deduction  and other  worksite
marketing techniques.

For  more  than 75  years,  Combined  Insurance  Company  of  America  has  sold
supplemental  life,  health and accident  coverage to individuals in their homes
and at their place of work.

Combined  Insurance  Company of America in brief: 

   o  Operations in the U.S., U.K., Canada, Australia, Ireland, Germany, Mexico,
      New Zealand, The Netherlands and Argentina

   o  Individual and employer insurance programs

   o  The largest issuer of individual  accident  policies in the U.S.,  Canada,
      Australia and Ireland

   o  The 4th  largest  writer  of  individual  accident  and  health  insurance
      premiums among U.S. companies

   o  The 2nd  largest  writer of  individual  accident  and health  premiums in
      Canada

Management's Analysis of Operating Results and Financial Condition

CONSOLIDATED RESULTS
General
In 1997, Aon invested approximately $1.6 billion in business combinations in its
brokerage and consulting  businesses.  These business combinations were financed
primarily by the issuance of capital securities, internal funds and the issuance
of commercial paper. The major 1997 acquisitions include:  Alexander & Alexander
Services  Inc.  (A&A)--a  leading  global  insurance  brokerage  and  consulting
company;  Minet --a worldwide  specialty  reinsurance  and  wholesale  brokerage
operation;  Sodarcan --a Canadian insurance  brokerage and consulting  company;
and Jauch & Hubener --the largest  insurance  brokerage and  consulting  firm in
Germany. In fourth quarter 1996, Aon acquired Bain Hogg Group plc (Bain Hogg), a
leading insurance broker in the United Kingdom and Asia, for approximately $260
million.  These items were accounted for using the purchase method of accounting
and the goodwill created is amortized  principally over forty years.  Because of
these   acquisitions   all  brokerage   revenue  and  income   comparisons   are
significantly impacted.

In 1996,  Aon sold two of its  domestic  insurance  underwriting  subsidiaries,
Union Fidelity Life Insurance  Company (UFLIC) and The Life Insurance Company of
Virginia  (LOV) (see note 3). The  after-tax  proceeds  from the sales were $1.2
billion.  The sales resulted in a $21 million  after-tax gain on sale. UFLIC and
LOV  results  are  classified  in  the  consolidated  statements  of  income  as
discontinued  operations  in 1996  and  1995.  For  purposes  of the  following
consolidated  results  discussions  (1997 compared to 1996 and 1996 compared to
1995),  comparisons  against  prior  years'  results  are  based  on  continuing
operations.

In 1996, Aon sold the  distribution  rights of its North American auto extended
warranty business.  However, it is still being underwritten by Aon's subsidiary,
Virginia  Surety  Company,  Inc. As part of the same  transaction,  Aon sold its
North American auto credit  insurance and distribution  operations.  Results of
the auto credit underwriting  business written prior to the sale are continuing
to run off as planned.

Special Charges

All of Aon's special charges are reflected in commissions  and general  expenses
in the  consolidated  statements of income.  In first quarter 1997, Aon recorded
pretax  special  charges of $145  million  ($91  million  after-tax or $0.54 per
share),  primarily  related  to  management's  commitment  to a formal  plan of
restructuring Aon's brokerage  operations as a result of the acquisition of A&A.
Pretax restructuring  charges include approximately $105 million associated with
real estate activities including the closure,  abandonment and consolidation of
duplicate  facilities  around the world,  and other  consolidation  costs.  The
restructuring charges related to consolidating real estate space are expected to
be paid out over several years. Special charges for severance and related costs,
involving over 600 positions,  were  approximately  $40 million.  Terminations
resulting from workforce  reductions are substantially  complete.  In connection
with the first quarter 1997 special charges,  Aon had  approximately $80 million
remaining unpaid in the commissions and general  expenses  liability at December
31, 1997.

In  1997,  as  a  result  of  the   acquisition  of  A&A,  Aon  had  established
approximately  $200  million  of  purchase  accounting   liabilities  primarily
relating to costs associated with the  consolidation  of real estate  activities
and severance liabilities for approximately 2,000 positions.  In connection with
these  items,  Aon  had  approximately  $100  million  remaining  unpaid  in the
commission and general expense liability at December 31, 1997.

In second quarter 1997, Aon recorded  pretax special charges of $27 million ($17
million after-tax or $0.10 per share) to recognize investment losses incurred at
A&A before Aon acquired  A&A. Aon  discovered  in the second  quarter that A&A's
investment portfolio,  as it had been constructed before Aon's acquisition,  had
included  certain  highly  volatile   securities  which  had  been  incorrectly
classified as high quality money market instruments.  At Aon's acquisition date,
the carrying  value of certain  securities in A&A's  portfolio was overstated by
the previously unrecognized investment losses.

In second  quarter 1996,  Aon recorded a $30 million  pretax charge ($19 million
after-tax or $0.12 per share) related to a voluntary  early  retirement  program
for all eligible employees of Aon's United States (U.S.) operating  subsidiaries
and similar  programs in parts of Europe.  Approximately  450 employees,  60% of
whom were in the U.S., participated in the early retirement program.

In  fourth  quarter  1996,  Aon's  management  committed  to a  formal  plan  of
restructuring Aon's European brokerage  operations  primarily as a result of the
Bain Hogg  acquisition  and recorded  pretax special charges of $60 million ($40
million after-tax or $0.24 per share) primarily  relating to this activity.  The
restructuring  charges include $32 million relating to consolidating real estate
space and data  processing  facilities  and equipment,  primarily in Europe,  in
order  to  merge  Aon's  existing  operations  with  those  of  Bain  Hogg.  The
restructuring charges related to consolidating real estate space are expected to
be paid out over  several  years.  Special  charges  for  workforce  reductions,
involving approximately 300 positions, were $12 million.  Terminations resulting
from  work-force  reductions  took  place  within  one  year  from  the  date of
acquisition.  Costs  associated with special  assessments to be paid relating to
the  reconstruction  of the Lloyd's of London insurance market were $11 million.
The remaining charges  primarily reflect Aon's exit from certain U.S.  insurance
underwriting markets.

       MANAGEMENT'S ANALYSIS OF OPERATING RESULTS AND FINANCIAL CONDITION

In connection with the 1996 special charges,  Aon had  approximately $30 million
remaining in the commissions and general expenses liability at December 31, 1997
representing  amounts  related to the  special  charges  that have not yet been
paid.

As a result of the Bain Hogg acquisition,  approximately $85 million of purchase
accounting  liabilities were established  primarily  relating to both the costs
associated  with the  consolidation  of real  estate  activities  and  severance
liabilities.  In connection with these items, Aon had  approximately $55 million
remaining unpaid in the commission and general expense liability at December 31,
1997.

Revenue and Income Before Income Tax
Consolidated  Results for 1997 Compared to 1996

Total  revenues  amounted to $5.8  billion,  an  increase  of 48% in 1997.  This
increase was largely  attributable  to growth in brokerage  commissions and fees
resulting from business  combination  activity.  Brokerage  commissions and fees
increased 88% to $3.6 billion.

Premiums earned of $1.6 billion increased 5% in 1997. Extended warranty premiums
earned increased $110 million or 24% reflecting continued growth of new business
in the mechanical,  appliance and the electronic lines. There was minimal growth
in direct  sales  business  as a result of  changes  in the  consumer  insurance
market.  The planned  run-off of North American auto credit  business  partially
offset this growth in premiums earned.

Net  investment  income of $494  million  increased  29% for the year  primarily
attributable  to  brokerage  acquisitions,  and to income  received  on  certain
private equity investment holdings. The investment portfolio yield declined five
basis  points  as a result of  investment  of new cash  flows in lower  yielding
investments,   as  well  as  the  change  in  portfolio  mix   attributable   to
acquisitions.

Pretax realized  investment gains were $6 million in 1997 compared to $8 million
in 1996.  Revenue  excluding  realized  investment  gains  increased 48% or $1.9
billion when compared to 1996.

Commissions and general expenses  (excluding interest expense) increased 70% for
the year  primarily  due to  growth in the  brokerage  businesses.  Benefits  to
policyholders  increased 7% when compared to 1996, reflecting a higher volume of
new  extended  warranty  business,  as well as  growth in  capital  accumulation
products.  This increase was  partially  offset by the  profitable  phase out of
certain specialty liability programs and the run-off of auto credit business as
planned.  It is  anticipated  that this  business  will  continue  to run-off as
planned.  Interest expense  increased 73% as a result of acquisition  financing.
Amortization of intangibles,  which excludes  deferred policy  acquisition costs
(DPAC), increased $44 million or 58%, reflecting brokerage acquisitions.

Overall,  benefit and expense margins for the insurance underwriting segment did
not suggest any significant  shift in operating  trends in 1997.  Total benefits
and expenses  increased 51% or $1.8 billion over 1996. The increase reflects the
inclusion  of 1997 and 1996  pretax  special  charges  of $172  million  and $90
million, respectively.  Total benefits and expenses, excluding the 1997 and 1996
special  charges,  increased  50% over  1996,  primarily  reflecting  brokerage
acquisition activity.

References to income before income tax exclude minority  interest related to the
issuance of 8.205% mandatorily  redeemable preferred capital securities (capital
securities) (see note 8).

Income before income tax increased $96 million or 22% in 1997,  primarily due to
acquisition  activity.  Excluding  special  charges,  income  before  income tax
increased 33% or $178 million.

Fourth  quarter  revenue  increased  42% to $1.5 billion when  compared to 1996,
primarily reflecting brokerage business combination activity. Total benefits and
expenses,  excluding  special  charges,  increased  41% to $1.3  billion for the
quarter.  Pretax  income  increased  $126 million or 178% to $197  million.  The
increase in pretax  earnings  reflects  growth in the  insurance  brokerage  and
consulting segment related to business combination  activity.  Excluding special
charges, pretax earnings increased 50% compared to fourth quarter 1996.

       MANAGEMENT'S ANALYSIS OF OPERATING RESULTS AND FINANCIAL CONDITION

European  revenue  increased  72% in 1997 to $1.6  billion,  and  rest of  world
revenue of $0.7  billion  rose 137%.  European  pretax  income  before  special
charges  increased  83% to $201 million and rest of world pretax  income  before
special charges  increased to $100 million.  Both the revenue and pretax income
before special charges have increased primarily due to acquisitions.

Revenue and Income Before Income Tax
Consolidated  Results for 1996 Compared to 1995

Total revenue  amounted to $3.9 billion in 1996,  an increase of 12%.  Brokerage
commissions  and fees  increased  16% to $1.9 billion  resulting  from  business
combination  activity and internal growth.  Premiums earned were $1.5 billion or
7% above 1995.  A higher  volume of new business in the auto  extended  warranty
line and in both the electronic and appliance lines was partially  offset by the
continued  phase-out of certain  specialty  liability  programs.  Net investment
income of $384 million  increased 17% for the year  primarily  attributable  to
investment income associated with the proceeds from the sales of UFLIC and LOV.

Commissions and general expenses  (excluding interest expense) increased 17% for
the year  primarily  reflecting  brokerage  growth.  Benefits to  policyholders
increased  13% when  compared to 1995  primarily  due to a higher  volume of new
extended warranty  business.  This increase was partially offset by lower claims
paid on auto credit business that has been in run-off since second quarter 1996.
Interest expense increased 8% reflecting higher levels of short-term borrowings
for the year. Total benefits and expenses increased 14% over 1995. Income before
income tax  decreased  by 3% or $12  million  due  largely to the  inclusion  of
special charges.  Excluding special charges,  income before income tax increased
17% or $78  million,  largely  due to  growth  in the  insurance  brokerage  and
consulting  segment related to business  combination  activity,  as well as the
earnings associated with the proceeds from the sale of discontinued operations.

MAJOR LINES OF BUSINESS
General 

For  purposes of the major lines of business  discussion,  comparisons  against

Total 1997 brokerage and consulting  services revenue was $3.8 billion,  up 89%.
Included in insurance and other  services is retail revenue of $2.3 billion and
reinsurance & wholesale revenue of $0.9 billion.  Acquisitions accounted for the
majority of this revenue growth.  Excluding the impact of acquisitions,  revenue
and income before income tax results  related to brokerage core  businesses grew
approximately 5% in a very competitive environment.

Insurance and other services  results were positively  impacted by acquisitions,
especially the inclusion of A&A in 1997.  Retail brokerage  results continued to
reflect highly  competitive  property and casualty  pricing in the U.S. market.
Pretax income growth was slowed primarily due to market  pressures  experienced
in the reinsurance brokerage business.

Aon Warranty Group provides warranty  marketing and  administrative  services to
clients.  This activity  generated revenue of $75 million in 1997. Also included
in  insurance  and other  services  revenue are  financing  service  fees of $52
million, an increase of 49% over 1996.

In the consulting line of business, 1997 revenue increased 102% to $553 million.
Revenue growth was primarily influenced by acquisition activity and, to a lesser
extent,  expansion of integrated human resources consulting programs. The growth
of  consulting  revenue and pretax income was offset by a decline in revenues in
the automotive consulting operations.

Revenue was $1.9 billion in 1997, up 5% from $1.8 billion in 1996, primarily due
to growth in the worldwide  extended  warranty lines.  Direct sales business had
minimal growth reflecting  difficult market conditions for accident,  while life
and health grew  satisfactorily.  Direct  sales  continued to expand its product
distribution through work-site  marketing  programs.  Direct sales accident and
health  business  improved its pretax margin in part due to good general expense
controls and good  international  health product  sales.  The run-off of certain
specialty  liability programs is now substantially  complete,  while auto credit
business  continues to run-off.  Pretax  income was $278 million in 1997,  up 5%
from $264 million last year.

U.S.  revenue of $1.3 billion was up 2% in 1997 while European  revenue of $376
million  rose 22%,  principally  due to growth  in  premiums  earned in both the
extended  warranty  and capital  accumulation  products.  Rest of world  revenue
declined slightly. In addition, there was a higher volume of new business in the
appliance and  electronics  extended  warranty  lines,  both  domestically  and
internationally.  U.S.  pretax income before  special  charges rose 7% in 1997.
European pretax income  increased 25% while rest of world pretax income declined
$9 million.

Corporate and Other

Revenue  consists  primarily of  investment  income on  insurance  underwriting
operations' capital and realized investment gains. Insurance company investment
income is allocated to the  underwriting  segment  based on the invested  assets
which  underlie  policyholder  liabilities.  The remaining  invested  assets and
related investment income, which do not underlie these liabilities, are reported
in this  segment.  Expenses  include  interest  and  other  financing  expenses,
goodwill  amortization   associated  with  insurance  brokerage  and  consulting
acquisitions, and corporate administrative costs.

</TABLE>

Revenue  increased 6% over 1996 to $119  million.  Higher  levels of  investment
income received on certain private equity investment holdings contributed to the
increase. Realized investment gains declined $2 million in 1997 when compared to
1996. Excluding these gains from both years, revenue increased 9%.

Pretax income  decreased $73 million in 1997.  Contributing to the decrease were
interest expense and goodwill  amortization related to acquisitions.  Excluding
realized investment gains from both years, pretax income decreased $71 million.

Discontinued  Operations
Discontinued  operations in 1997 are comprised of certain insurance underwriting
subsidiaries   acquired   with  A&A  that  are  currently  in  run-off  and  the
indemnification  of certain  liabilities  relating to  subsidiaries  sold by A&A
prior  to  Aon's  acquisition.   Management  believes  that,  based  on  current
esti-mates, these discontinued operations are adequately reserved. The liability
is included as a component of other liabilities on the consolidated statement of
financial position.  The liability  increased during the fourth quarter of 1997
due to the commutation of a finite risk reinsurance contract (see note 3).

Discontinued  operations  in 1996 and prior were  composed  principally  of U.S.
based capital  accumulation  products and direct  response  insurance  products.
After-tax  income  on these  businesses  has been  segregated  as  "Income  From
Dis-continued  Operations" in the  consolidated  statements of income.  With the
completion  of the  sales of  UFLIC  and LOV on April  1,  1996,  there  were no
operating results from these discontinued operations going forward.

INCOME TAX AND NET  INCOME 

On March 21, 1997,  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. The
earnings  per share and  average  shares  outstanding  have  been  restated  for
Financial  Accounting  Standards  Board (FASB)  Statement  No. 128 "Earnings Per
Share," and the following discussion is on a dilutive basis. Basic net income on
a per share basis was $1.71 and $1.93 in 1997 and 1996, respectively.

Net income for 1997 was $299 million or $1.68 per share compared to $335 million
or $1.90 per share in 1996.  Net income for fourth quarter 1997 amounted to $113
million or $0.65 per share  compared to $46 million or $0.25 per share for 1996.
The  decrease  in 1997 net  income and  related  per share  amount is  primarily
influenced  by: (1) after-tax  1997 special  charges of $108 million  ($0.64 per
share)  compared to  after-tax  1996 special  charges of $59 million  ($0.36 per
share);  (2) the 1997  deduction  for  after-tax  distributions  on the  capital
securities  (reflected as "minority  interest" on the consolidated  statement of
income);  (3) operating  results from 1996  discontinued  operations  due to the
completion  of the sales of UFLIC  and LOV in second  quarter  1996  ($0.13  per
share);  and (4)  after-tax  gain on sale of  discontinued  operations  in 1996
($0.13 per share).  Dividends on the 8% and redeemable  preferred stocks in 1997
and dividends on the 8%, 6.25% and redeemable  preferred stocks in 1996 and 1995
have been deducted from net income to compute earnings per share.

Operating income from continuing  operations before special charges and realized
investment  gains,  was $402 million or $2.30 per share in 1997 compared to $346
million or $1.97 per share in 1996. Aon's effective operating income tax rate on
continuing  operations was 37.5% in 1997 and 34.5% in 1996.  Realized investment
gains were taxed at 37.5% and 36% for 1997 and 1996, respectively.

Average  shares  outstanding  for 1997  increased 1%  primarily  due to business
combinations.

LIQUIDITY 

Consistent with financial statement  presentation,  the  following cash flow and
financial position  discussion  primarily reflects  brokerage  acquisitions.  In
addition,  the sales of UFLIC and LOV in 1996 have  significantly  impacted  the
consolidated statements of equity and cash flows.

Aon's operating  subsidiaries  anticipate that there will be adequate liquidity
to meet their needs in the foreseeable future. Aon's routine liquidity needs are
primarily  for  servicing  its debt and for the  payment of  dividends  on stock
issues and the capital  securities.  Dividends from Aon's  subsidiaries  are the
primary  source for  meeting  these  requirements.  After  meeting  its  routine
dividend and debt servicing requirements,  Aon used a majority of the remaining
dividends received throughout the year to invest in the operational segments of
its businesses.  There are certain regulatory restrictions relating to dividend
capacity of  insurance  subsidiaries  that are  discussed  in note 8.  Insurance
subsidiaries'  statutory capital and surplus at year end 1997 again exceeded the
risk-based  capital  target  set  by  the  National   Association  of  Insurance
Commissioners  by a satisfactory  level.  At December 31, 1997, Aon had back-up
lines of credit available of $900 million.

The businesses of Aon's operating  subsidiaries continue to provide substantial
positive cash flow. Brokerage cash flow has

                                     - 22 -
<PAGE>
       MANAGEMENT'S ANALYSIS OF OPERATING RESULTS AND FINANCIAL CONDITION

been used  primarily  for  acquisition  related  activities.  Given  Aon's fixed
maturity  portfolio's  average life of 6.3 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.

In 1997, Aon completed various acquisitions with an aggregate purchase price of
approximately  $1.6  billion,  which were funded by the  issuance of  commercial
paper,  internal funds, and the issuance of $800 million of capital  securities.
The  capital  securities  are  designated  on  the  consolidated  statements  of
financial  position  as  "Company-obligated   Mandatorily  Redeemable  Preferred
Capital  Securities of  Subsidiary  Trust holding  solely the Company's  Junior
Subordinated Debentures" (see note 8).

Cash  flow  from  operations  per the  Consolidated  Statements  of Cash  Flows
increased  $430  million  from 1996 to $784  million.  This  increase  primarily
reflects 1997 brokerage acquisitions, the timing of the settlement of insurance
segment receivables and payables,  and payments on special charges and valuation
adjustments relating to the acquisitions.

Investing activities used cash of $1.4 billion in 1997, which was made available
from financing and operating  activities.  Investing activities provided cash of
$238 million in 1996.

Cash totaling $1.3 billion was provided by financing  activities  in 1997.  The
increase  primarily  reflected the issuance of commercial paper and the proceeds
from the sale of the capital securities. Partially offsetting this increase was
the use of funds to purchase and retire  5,446,000  shares of the 8%  preferred
stock at a total  cost of $136  million.  The net cash  provided  from  capital
accumulation product deposits and withdrawals was $329 million in 1997. Cash was
used to pay  dividends  of $169 million on common  stock,  $11 million on the 8%
preferred stock, and $2 million on redeemable preferred stock.

Total assets  increased  $5.0 billion to $18.7  billion,  primarily  due to the
brokerage  acquisitions.  Invested  assets at December 31, 1997  increased  $709
million from year end 1996 levels.

Year 2000

Aon began work on the  computer  Year 2000 issue in 1995 and expects to complete
its  efforts  by mid  1999.  Software  applications,  hardware,  and  technology
infrastructure  have been  upgraded  or replaced  both to improve the  computing
capabilities  for all  businesses  and  ensure  that all  systems  are Year 2000
compliant.  Replacing  hardware  and  software in this  fashion is  considered a
normal  cost  of  doing  business  and  is  being  expensed  or  capitalized  as
appropriate.  Aon's  Year 2000  remediation  cost for all lines of  business  is
expected to be less than $50 million through 1999.

Aon has  established  a full-time  Year 2000 project  coordinator  and a global
contact for all major business units. The effort includes  representatives  from
Aon's legal and internal  audit  staffs.  In addition,  individual  Aon business
units have formally  evaluated their Year 2000 compliance status in a survey and
are  identifying   specific  hardware  and  software   compliance  issues  where
appropriate.  These  inventories  include Aon's internal systems and services as
well  as  exposure  from  suppliers,  service  providers,  and  customers.  The
individual  business  units  will be  making  the  necessary  changes  to become
compliant  according to their plans and the progress  will be monitored by Aon's
Year 2000 compliance coordinating team.

Aon has established a program to contact  insurance  underwriters  and external
business  partners in connection with their Year 2000 compliance  programs.  Aon
does  not  warrant,   however,   that  these  companies'  Year  2000  compliance
activities will be completely successful.

INVESTMENT OPERATIONS

Aon invests in broad asset  categories  related to its  diversified  operations.
Investments are managed with the objective of maximizing earnings while matching
asset and liability durations and considering regulatory requirements.

Aon maintains  well-capitalized  operating companies.  The financial strength of
these  companies  permits  an  overall  diversified   investment  portfolio  for
stability in volatile financial markets.

Investment  characteristics  mirror liability  characteristics of the respective
operating  units.  Aon's insurance  brokerage and consulting  businesses  invest
fiduciary   funds   in   shorter-term   obligations.    Investments   underlying
interest-sensitive   capital  accumulation  insurance  products  are  primarily
intermediate-term obligations, while indemnity and other types of non-interest
sensitive  insurance  liabilities  are primarily  supported by  intermediate to
long-term instruments.  Longer-term assets which support capital include private
equity  investments  that are  expected to  generate  returns in excess of those
available in the public capital markets.

With a carrying value of $3.1 billion,  Aon's total fixed maturity portfolio is
invested  primarily in investment  grade holdings  (96.4%) and has a fair value
which is 104.3% of amortized cost.

Market Risk  Exposure

Aon is subject to various market risk exposures  including foreign exchange rate
risk,  interest  rate risk,  and equity  price risk.  The  following  disclosure
reflects estimates of future performance and economic conditions. Actual results
may differ.

Aon is  subject  to  foreign  exchange  rate risk  associated  with  translating
financial   statements   of  its  foreign   subsidiaries   into  U.S.   dollars.
Additionally,  certain  of  Aon's  foreign  subsidiaries  receive  revenues  in
currencies that differ from the currency in which their  operating  expenses are
denominated.  Aon's primary exposures are associated with the British Pound, the
Dutch Guilder, the Canadian Dollar, the Australian Dollar, and the German Mark.
Aon uses forward  contracts and foreign currency futures and options to protect
against  adverse  transaction  and  translation  effects  due to  exchange  rate
fluctuations. The potential decrease to Aon's consolidated equity resulting from
a hypothetical 10% adverse change in quoted year end foreign  currency  exchange
rates amounts to $120 million. The impact to pretax net income in the event of a
hypothetical  10% adverse change in the quoted year end exchange rates would not
be material after consideration of derivative positions.

Due to the  nature of Aon's  businesses,  operating  earnings  are  affected  by
changes in  international  and domestic  short-term  interest rates.  Aon hedges
against   fluctuations   in  short-term   interest  rates  with  Eurodollar  and
Eurosterling futures contracts,  interest rate swaps, and interest rate caps. A
hypothetical  1%  decrease in  interest  rates  would have a  decrease,  net of
derivative  positions,  of $24 million to pretax income. Aon's earnings are also
affected by interest rate risks related to short-term borrowings. A hypothetical
1% decrease in short-term  interest rates would  correspondingly  decrease Aon's
interest  expense by $8 million,  partially  offsetting  the loss of  short-term
investment income.

The valuation of Aon's fixed maturity portfolio is subject to long-term interest
rate risk.  Aon generally  uses  treasury  options and futures and interest rate
swaps to hedge the value of the fixed  maturity  portfolio.  A  hypothetical  1%
increase  in  long-term  interest  rates  would  decrease  the fair value of the
portfolio,  net of derivative positions, by approximately $155 million. Aon has
long-term notes payable and capital securities  outstanding at December 31, 1997
with a fair value of $1.5 billion.  Such fair value exceeded the carrying value
by  approximately  $100 million.  A  hypothetical  1% decrease in interest rates
would increase the fair value by approximately 10%.

The valuation of Aon's  marketable  equity  portfolio is subject to equity price
risk.  If market  prices  were to  decrease  10%,  the fair  value of the equity
portfolio would have a corresponding  decrease of $81 million.  At December 31,
1997 there were no outstanding  derivatives hedging the price risk on the equity
portfolio.

CAPITAL RESOURCES In 1997,  short-term  borrowings increased $551 million.  This
increase was  primarily  attributable  to  commercial  paper used  primarily for
acquisition  activity.  Notes  payable  increased  in 1997 by $116  million when
compared to year end 1996, due to both acquisition financing and acquired debt.

On November 3, 1997,  Aon  exercised  its option to redeem all of the  remaining
outstanding  shares of 8% preferred  stock at a  redemption  price of $25.00 per
share  plus  accrued  dividends.  The cost of  repurchasing  these  shares  was
approximately $136 million, financed primarily by short-term borrowings.

Aon Corporation borrows funds from and lends funds to its various  subsidiaries.
As of December 31, 1997, Aon Corporation held obligations to its subsidiaries of
approximately  $0.5 billion.  Generally,  these  obligations have  competitive
interest rates.

In 1997,  common  stockholders'  equity per share  increased to $16.80,  up from
$16.21 in 1996. Total  stockholders'  equity decreased $11 million primarily due
to the retirement of the 8% preferred  stock and the foreign  exchange loss. The
foreign  exchange  loss  results  from  lower  exchange  rates at year end 1997
compared to year end 1996 for most major European currencies. Principal factors
favorably  contributing to equity were net income and net unrealized  investment
gains.

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).  These
statements  include  informed  estimates and assumptions that affect the amounts
reported.  Actual results could differ from the amounts  reported.  All material
intercompany accounts and transactions have been eliminated.

Segment Information

Aon  Corporation  is a  multinational  holding  company.  Its  businesses  serve
consumers and  commercial  operations in North America,  South America,  Europe,
Africa,  Asia and Australia.  Aon's continuing  operations are concentrated into
two core  businesses.  Insurance  brokerage  and  consulting  services  provide
services for commercial,  industrial and insurance  company clients.  Insurance
underwriting  provides life, accident and health insurance and extended warranty
products for individual  consumers,  delivered through controlled  distribution
channels.

The  segment  information  located  in the  tables  on  pages 19  through  22 is
incorporated herein by reference.

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.

Recognition of Premium  Revenue 

In general,  for accident and health and extended  warranty  products,  premiums
collected are reported as earned in proportion to insurance  protection provided
over the  period  covered  by the  policies.  For life  products,  premiums  are
recognized as revenue when due.

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. Reinsurance receivables and prepaid
reinsurance premium amounts are reported as assets.

Special Charges 

The  special  charges  information  located  on pages 18 and 19 is  incorporated
herein by reference.

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 is  computed in  accordance  with the  Financial  Accounting
Standards Board (FASB) Statement No. 128 "Earnings Per Share."

Basic  earnings per share is computed  based on the weighted  average  number of
common shares outstanding, excluding any dilutive effects of options, awards and
convertible  securities.  Common shares  outstanding  include 4,230,000 shares,
4,520,000  shares and 4,901,000 shares held by the employee stock ownership plan
in 1997, 1996 and 1995, respectively. Income available to common shareholders is
net of all preferred  dividends.  Dilutive earnings per share is computed based
on the weighted  average number of common shares  outstanding  plus the dilutive
effects of options,  awards and convertible  securities.  The dilutive effect of
options and awards is  calculated  under the  treasury  stock  method  using the
average  market  price  for the  period.  Earnings  per share is  calculated  as
follows:

</TABLE>

A  three-for-two  stock split of Aon's $1.00 par value common stock was effected
on May 14, 1997 with 57 million shares issued to common  stockholders  of record
as of May 1, 1997. All references in the accompanying  financial  statements and
retroactively restated to reflect the stock split.

Investments  

Fixed maturities are available for sale and are carried at fair value.  The
amortized cost of fixed  maturities is adjusted for  amortization of premiums to
the first call date and the accretion  

                                     - 30 -

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

of discounts  to maturity  that are 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.  Other  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, which are judged to be
other than  temporary,  are written down to estimated fair values.  Reserves for
certain  other  investments  are  established  based  on an  evaluation  of  the
respective investment portfolio and current economic conditions. Write-downs and
changes in reserves are included in realized investment gains and losses in the
consolidated  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 11.

Deferred Policy Acquisition Costs

Costs of acquiring new and renewal insurance underwriting business,  principally
the excess of new commissions over renewal  commissions,  underwriting and sales
expenses  that vary with and are  primarily  related  to the  production  of new
business, are deferred. For long-duration life and health products, amortization
of deferred  policy  acquisition  costs is related to and based on the  expected
premium revenues of 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
extended warranty and  short-duration  health insurance,  costs of acquiring and
renewing business,  which are deferred,  are amortized as the related premium is
earned.

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 other  intangible  assets
purchased of certain  subsidiaries  is being  amortized  over a range of 4 to 25
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,   including   short-term
investments,  approximate  their fair value.  Fair value for fixed maturity and
equity  securities is based on quoted market prices or, if they are not actively
traded,  on estimated values obtained from independent  pricing  services.  Fair
value of derivatives is based on quoted prices for  exchange-traded  instruments
or the cost to terminate or offset with other contracts.

In general,  other  investments are comprised of mortgage  loans,  policy loans,
real estate joint ventures and limited partnerships. The fair value for mortgage
loans and policy loans is estimated using  discounted cash flow analyses,  using
interest  rates  currently  being offered for similar  loans to borrowers  with
similar  credit  ratings.  It was not  practicable to estimate the fair value of
joint  ventures and limited  partnerships  because of 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 value for liabilities  for  investment-type  contracts is 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 for notes payable is 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.

Future Policy Benefits, Unearned Premiums, and Policy and  Contract Claims

Future policy benefit  liabilities on non-universal life 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 7.0%
to 5.0% at December 31, 1997.  Withdrawal  assumptions are based  principally on
insurance  subsidiaries'  experience  and  vary  by  plan,  year of  issue,  and
duration. Policyholder liabilities on universal life and investment products are
generally based on policy account values.

Unearned  premiums  generally are calculated  using the pro rata method based on
gross premiums. However, in the case of 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

In general,  foreign  revenues and expenses are  translated at average  exchange
rates.  Foreign assets and  liabilities  are  translated  at year-end  exchange
rates.  Net  foreign  exchange  gains and losses on  translation  are  generally
reported in stockholders'  equity,  net of deferred income tax. The deferred tax
benefit of foreign exchange losses is $51 million at December 31, 1997, compared
to the deferred tax effect of foreign  exchange  gains of $1 million at December
31, 1996 and 1995.

Accounting  Changes 

In 1997,  the FASB issued  Statement No. 128,  "Earnings Per Share." Aon adopted
this statement in its December 31,

                                     - 31 -
<PAGE>
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1997 financial statements and has restated prior periods presented as required.
Implementation  of this  Statement  did not  have a  material  effect  on  Aon's
financial statements.

In 1997, the FASB issued Statement No. 130,  "Reporting  Comprehensive  Income."
This Statement establishes  standards for reporting and classifying  components
of  comprehensive  income in the  financial  statements  and requires  that the
accumulated balance of other comprehensive  income be displayed  separately from
retained  earnings and  additional  paid-in-capital  in the equity  section of a
statement  of  financial  position.  The FASB also  issued  Statement  No. 131,
"Disclosures  about Segments of an Enterprise and Related  Information" in 1997.
This  Statement  establishes  standards  for  providing  disclosures  related to
products and services,  geographic  area, and major  customers.  Aon anticipates
adopting  these  statements  in  its  1998  financial  statements  as  required.
Implementation  of these statements is not expected to have a material effect on
Aon's financial statements.

In 1997,  Aon adopted FASB  Statement  No. 125,  "Accounting  for Transfers and
Servicing   of   Financial   Assets  and   Extinguishments   of   Liabilities."
Implementation  of this  Statement  did not  have a  material  effect  on  Aon's
financial statements.

In 1996,  Aon adopted the  disclosure  requirements  of FASB  Statement No. 123,
"Accounting for Stock-Based Compensation." As allowed by Statement No. 123, Aon
chose to continue to account for stock-based  compensation  using the intrinsic
value  method  prescribed  in  Accounting   Principles  Board  Opinion  No.  25,
"Accounting  for Stock Issued to Employees,"  and related  Interpretations  (see
note 10).

Reclassification 

Certain amounts in the prior years' consolidated  financial statements have been
reclassified to conform to the 1997 presentation.

2.  BUSINESS  COMBINATIONS
Purchase Method 

In 1997, Aon acquired Alexander & Alexander Services Inc. (A&A), the Minet Group
(Minet)  and Jauch & Hubener  for  approximately  $1.6  billion in  transactions
accounted for by the purchase  method.  Certain  purchase price  allocations for
1997 acquisitions will be finalized in 1998. Additionally,  Aon acquired certain
other  operations  at an aggregate  cost of $86 million and $110 million in 1996
and 1995,  respectively.  The 1997 acquisitions were financed  primarily by the
issuance of capital  securities (see note 8), issuance of commercial  paper and
internal funds. Intangible assets of approximately $1.5 billion were created by
these acquisitions. In 1997, as a result of the A&A acquisition, Aon established
approximately  $200  million  of  purchase  accounting  liabilities,  primarily
relating to severance and related costs for approximately 2,000 terminations and
the  consolidation of real estate space. In connection with these items, Aon had
approximately  $100  million  remaining  unpaid in the  commission  and general
expense  liability  at December  31, 1997.  The 1997  consolidated  statement of
income  included  the  operations  of A&A  since  January  1,  1997.  If the A&A
acquisition  had been  consummated on January 1, 1996, the unaudited  proforma
consolidation  results of operations  would have  resulted in total  revenues of
$5.2 billion,  income from continuing  operations of $258 million and net income
of $291 million.

In October 1996, Aon acquired Bain Hogg for  approximately  $260 million.  This
acquisition was financed by internal funds. The 1996 consolidated  statement of
income  includes  the  operations  of Bain Hogg since the date of  acquisition.
Aon's 1996 revenues would have been  approximately  $260 million greater had the
acquisition  occurred  on  January  1, 1996.  As a result of this  acquisition,
approximately $85 million of purchase  accounting  liabilities were established
primarily  relating to both the costs associated with the  consolidation of real
estate activities and severance liabilities. In connection with these items, Aon
had  approximately  $55 million  remaining  unpaid in the commission and general
expense liability at December 31, 1997.

Pursuant to a 1994 purchase  agreement,  Aon is contingently liable through 1999
to issue up to  292,000  additional  shares of common  stock  based on a formula
relating  to future  earnings  of that  operation.  In  accordance  with a 1992
purchase  agreement,  securities  with a value of $50  million are being held in
escrow.  The escrowed  securities will be released on a  predetermined  schedule
between 1998 and 2007.

Pooling of Interests  Method

In 1997, 1996 and 1995, Aon issued 274,000 shares,  819,000 shares and 2,106,000
shares of common stock,  respectively,  for mergers with insurance brokerage and
consulting  organizations.  In connection with several of the mergers,  760,000
shares issued to sellers are being held in escrow at December 31, 1997,  pending
the resolution of contingencies.  Aon's prior period financial  statements have
not been  restated for the mergers  because the effect of the above  mergers was
not material.

3. DISCONTINUED  OPERATIONS 

In April 1996, Aon completed the sales of its domestic  direct response life and
health  subsidiary,  Union  Fidelity  Life  Insurance  Company  (UFLIC) and its
capital  accumulation life insurance  subsidiary,  The Life Insurance Company of
Virginia (LOV) to General Electric Capital  Corporation and received  after-tax
sales proceeds of approximately $1.2 billion.  The gain on sale of discontinued
operations was $21 million, net of taxes.

For 1996 and 1995, the discontinued  operations had revenues of $293 million and
$1,145  million,  respectively.  The  revenues and  corresponding  benefits and
expenses were reported on a net basis in the consolidated  statements of income,
and  were  net of  taxes  of $12  million  and $53  million  in 1996  and  1995,
respectively.  Income from discontinued operations that was earned subsequent to
the  commitment  to the plan to dispose was $22 million and $15 million,  net of
taxes, in 1996 and 1995, respectively.

Included in discontinued operations is pretax interest expense of $5 million and
$18 million in 1996 and 1995,  respectively.  The allocation of interest expense
was based on the ratio of discontinued net assets to total  consolidated  equity
and debt.

                                     - 32 -

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


A&A's   Discontinued   Operations  

A&A  discontinued its insurance  underwriting  operations in 1985, some of which
were then placed into run-off,  the remainder  sold in 1987. In connection  with
those sales, A&A provided indemnities to the purchaser for various estimated and
potential liabilities,  including provisions to cover future losses attributable
to  insurance  pooling  arrangements,  a stop-loss  reinsurance  agreement,  and
actions or omissions by various  underwriting  agencies previously managed by an
A&A subsidiary.

As  of  December  31,  1997,  the  liabilities  associated  with  the  foregoing
indemnities and  liabilities of insurance  underwriting  subsidiaries  that are
currently  in run-off were  included in other  liabilities  in the  accompanying
statement of financial position and amount to $152 million. Such liabilities are
net of reinsurance recoverables and other assets of $176 million.

The  insurance  liabilities  represent  estimates  of known  and  future  claims
expected to be made under  occurrence-based  insurance  policies and reinsurance
business covering principally  asbestos,  environmental  pollution,  and latent
disease  risks in the United  States along with  substantial  litigation-related
expenses.  Those  claims are  expected to develop  and be settled  over the next
twenty to thirty years.

The insurance  liabilities  cannot be estimated  using  conventional  actuarial
reserving  techniques  because  of,  among  other  matters,  the  inadequacy  of
available historical  experience to support such techniques and because case law
and  scientific  standards for measuring the adequacy of site clean-up are still
evolving.  Therefore,  independent  actuaries have combined  available exposure
information with other relevant  industry data and have used various  projection
techniques  to estimate the insurance  liabilities,  which  liabilities  consist
principally of incurred but not reported losses.

Although  these  insurance  liabilities  represent  A&A's best  estimate  of the
probable  liabilities,  adverse  developments may occur due to the nature of the
information  available  to A&A  and the  variables  inherent  in the  estimation
processes. Based on current estimates,  management believes that the established
liabilities of discontinued operations are sufficient to cover A&A's exposures.

Debt Guarantee of ESOP 

Aon's ESOP has entered into loan  agreements to purchase Aon common  stock.  The
loans are unconditionally guaranteed by Aon and therefore the unpaid balance of
the loans is  classified  as notes  payable in the  accompanying  statements  of
financial position. An equivalent amount, representing deferred compensation, is
recorded as a deduction from  stockholders'  equity.  The ESOP paid $16 million,
$15  million  and $14  million in 1997,  1996 and 1995,  respectively,  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.  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. The ESOP allocated 642,000 shares in
1997. The remaining  unallocated  shares at December 31, 1997,  will be released
for allocation annually through 1999.

The following table details the shares held by the ESOP:

=======================================================================

As of December  31, 1997, a U.S.  subsidiary  of Aon (A&A) had U.S.  federal net
operating loss  carryforwards  of $96 million which expire in years 2008 through
2010, and federal foreign tax credit  carryforwards  of $18 million which expire
in years 1998 through 2000.

The Internal Revenue Code imposes  limitations on the utilization of federal net
operating  loss  and tax  credit  carry-forwards  after  a  change  of  control,
consequently,  there will be annual  limitations on the realization of these tax
assets.  Accordingly,  in  connection  with the  purchase  of A&A, a $56 million
valuation allowance was established.  Subsequently  recognized tax benefits for
these items would reduce goodwill.  Although future earnings cannot be predicted
with  certainty,  management  currently  believes that  realization  of the net
deferred tax asset after consideration of the valuation allowance is more likely
than not.

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, 1997, 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 taxes payable
would be $127 million.


The amount of income taxes paid in 1997,  1996 and 1995 was $137  million,  $387
million and $256 million, respectively.

7. 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 insurers.  Aon's insurance  subsidiaries  would remain liable to
the extent that the reinsuring companies were unable to meet their obligations.

A summary of reinsurance activity is as follows:

8. REDEEMABLE PREFERRED STOCK, CAPITAL SECURITIES AND STOCKHOLDERS' EQUITY

Redeemable Preferred Stock 

At December  31,  1997,  1,000,000  shares of  redeemable  preferred  stock are
outstanding.  Dividends are cumulative at an annual rate of $2.55 per share. The
shares of redeemable preferred stock will be redeemable at the option of Aon or
the holders, in whole or in part, at $50.00 per share no sooner than February 9,
1999.

Capital Securities 

In January 1997,  Aon created Aon Capital A, a wholly-owned  statutory  business
trust,  for the  purpose of issuing  mandatorily  redeemable  preferred  capital
securities (Capital Securities). The sole asset of Aon Capital A is $824 million
aggregate  principal  amount of Aon's  8.205%  Junior  Subordinated  Deferrable
Interest  Debentures  due  January  1,  2027.  The  back-up  guarantees,  in the
aggregate, provide a full and unconditional guarantee of the Trust's obligations
under the Capital Securities.

Aon Capital A issued $800 million of 8.205% capital securities in January 1997.
The proceeds from the issuance of the capital  securities were used to finance a
portion of the A&A acquisition.  The capital securities are subject to mandatory
redemption on January 1, 2027 or, are  redeemable in whole,  but not in part, at
the option of Aon upon the  occurrence  of certain  events.  Interest is payable
semi-annually on the capital securities. The capital securities are categorized
on the  consolidated  statement  of  financial  position  as  "Company-obligated
Mandatorily Redeemable Preferred Capital Securities of Subsidiary Trust holding
solely the Company's Junior  Subordinated  Debentures."  The after-tax  interest
incurred on the  capital  securities  is  reported  as minority  interest on the
consolidated statement of income.

8% Cumulative Perpetual Preferred Stock

At December 31, 1996,  5,446,000  shares of 8%  cumulative  perpetual  preferred
stock were  outstanding.  Dividends were  cumulative at the annual rate of $2.00
per share.  In November  1997,  Aon  purchased and retired all of the remaining
outstanding shares at a total cost of $136 million.

6.25% Cumulative Convertible Exchangeable Preferred Stock

At  December  31,  1995,  2,136,000  shares  of  6.25%  cumulative  convertible
exchangeable preferred stock were outstanding. Dividends were cumulative at the
annual rate of $3.125 per share. In November 1996, each share of 6.25% preferred
stock was converted by the holders into 1.83 shares of com-mon stock for a total
of 3,909,000 common shares.

Common Stock 

Aon repurchased 202,000,  1,931,000 and 2,969,000 shares in 1997, 1996 and 1995,
respectively,  of its  common  stock,  primarily  to  provide  shares  for stock
compensation plans and the conversion of preferred stock.

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 6 for  possible  tax
effects of distributions made out of untaxed earnings.

Net statutory income of the insurance  subsidiaries  (including LOV and UFLIC in
1995 and the statutory gain on the sale of LOV and UFLIC in 1996), is summarized

9. EMPLOYEE BENEFITS

Savings and Profit Sharing Plans

Certain  of Aon's  subsidiaries  maintain  contributory  savings  plans  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 plans are based
on a match of 100% of employee  contributions up to a maximum of 3% of eligible
compensation. Provisions made for these plans were $22 million in 1997, and $14
million in 1996 and 1995, respectively.  The provision made in 1997 increased as
compared to 1996 primarily due to the acquisition of A&A.

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 amounted to $14 million, $12 million and $11 million in 1997, 1996 and
1995, respectively.

 Domestic Pension Plan 

Certain of Aon's subsidiaries maintain  non-contributory defined benefit pension
plans  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 plans 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 1997, 1996 and 1995 is as follows:

In April  1996,  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 1996 resulting from the program was
$19  million.  Also in 1996,  Aon  completed  the sales of LOV and  UFLIC  which
resulted in a curtailment  gain of $8 million  which is included in the gain on
sale of  discontinued  operations.  As a result  of the  sales  of these  units,
affected  employees became fully vested in their accrued benefits in the defined
benefit plan.

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 plans.

1997 includes the A&A pension plan,  including a projected benefit obligation of
$336 million and plan assets at fair value of $469 million.

Plan assets include  marketable  equity securities and corporate and government
debt securities, including securities issued by Aon totaling $50 million and $35
million in 1997 and 1996, respectively.

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.

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.  The  employer's  liability  for  future  plan cost
increase  is  limited  in any year to 5% per  annum.  All plans are  funded on a
pay-as-you go basis.

In 1996,  Aon completed  the sales of LOV and UFLIC  resulting in a curtailment
gain of $5  million  which  was  included  in the  gain on sale of  discontinued
operations.

The following table sets forth the plans' combined funded status:

For  measurement  purposes  in 1997,  1996 and 1995,  an 8.5%,  9.5% and  10.5%,
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 6% 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.

Assumptions used in determining the APBO are summarized below:

10. STOCK COMPENSATION PLANS

Stock Award Plan

In 1997,  Aon's  stockholders  approved an amendment to the Aon Stock Award Plan
that  increased the aggregate  number of common stock that Aon could award up to
12,900,000 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.  In general,
most  awarded  shares are issued as they become  vested.  With  certain  limited
exceptions,  any break in  continuous  employment  will cause  forfeiture of all
unvested awards.  The  compensation  cost associated with each award is deferred
and amortized over the period of continuous  employment  using the straight line
method.

Aon common stock awards outstanding consist of the following:

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. In 1997,  Aon's  stockholders  approved an
amendment to the Aon Stock Option Plan that  increased the  aggregate  number of
common stock that Aon could issue up to 23,300,000 shares. Generally, the option
plan requires employees to complete three continuous years of service before the
options begin to vest in increments until the completion of a seven-year period
of continuous employment.

Aon applies  Accounting  Principles  Board Option No. 25,  "Accounting for Stock
Issued to Employees," and related  interpretations  in accounting for its plans.
Accordingly,  no  compensation  expense has been  recognized for its stock-based
compensation  plans other than the Aon Stock Award Plan. Had  compensation  cost
for the stock award and the stock  option plans been  determined  based upon the
fair value at the grant date for these plans  consistent  with the  methodology
prescribed  under  Statement No. 123,  Aon's net income and net income per share
for 1997,  1996 and 1995 would  have been  reduced  to the  following  pro forma
amounts:

===========================================================================================
</TABLE>

The fair value per share of options and awards  granted is  estimated  as $8.97
and  $41.59 in 1997,  $8.19 and  $30.87 in 1996,  and $5.60 and  $22.39 in 1995,
respectively,  on the grant date using the  Black-Scholes  option  pricing model
with  the  following  weighted  average  assumptions:  dividend  yield  of 2.5%;
expected  volatility of 20%, risk-free interest rate of 6%; and an expected term
life of 1.35  years and 0 years for the stock  option  plan and the stock  award
plan,  respectively.  The  compensation  cost as generated by the  Black-Scholes
model, may not be indicative of the future benefit, if any, that may be received
by the option holder.

The  proforma  information  reflected  above  may not be  representative  of the
amounts to be expected in future  years as the fair value  method of  accounting
contained  in FASB  Statement  No. 123 has not been  applied to options  granted
prior to January 1995.

11. FINANCIAL INSTRUMENTS

Financial Risk Management

Aon is exposed to market risk from changes in foreign currency  exchange rates,
interest  rates and equity  prices.  To manage the  volatility  related to these
exposures,  Aon enters into various derivative transactions that have the effect
of reducing these risks by creating offsetting market exposures.  If Aon did not
use derivative contracts, its exposure and market risk would be higher.

Derivative  transactions  are  governed  by  a  uniform  set  of  policies  and
procedures  covering  areas such as  authorization,  counterparty  exposure  and
hedging practices. Positions are monitored using techniques such as market value
and sensitivity analyses.

In addition  to  creating  market  risks that  offset the  underlying  business
exposures,  certain  derivatives  also give rise to credit risks due to possible
non-performance by counterparties.  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.  Aon closely monitors the  creditworthiness  of and exposure to its
counterparties  and  considers  its credit risk to be minimal.  At December 31,
1997 and 1996, Aon placed  securities in escrow  amounting to $6 million and $13
million, respectively, relating to these derivative contracts.

Foreign Exchange Risk Management 

Aon uses foreign currency futures, options, and forward contracts to manage the
effects of foreign  currency  fluctuations  on the  translation of the financial
statements of Aon's foreign operations.  Generally,  related gains and losses on
these  contracts  are reflected as an  adjustment  to income when settled.  For
contracts  designated  as hedges of a net  investment  in  foreign  subsidiary,
realized and unrealized gains are recorded directly to stockholders' equity as a
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 expenses are denominated.
To reduce the variability of cash flows from these operations,  foreign forward
exchange  contracts and options 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.  Forward  contracts
entered into  require no up-front  premium and settle at the  expiration  of the
related contract.

Interest Rate Risk Management

Aon uses  interest  rate  derivative  contracts to manage the interest rate risk
associated  with  assets  and  liabilities   underlying  its  underwriting  and
brokerage businesses.  Interest rate derivatives are also utilized to manage the
company's funding and other corporate risks.

Interest rate swap agreements are used to manage asset and liability  durations.
Exchange-traded  Eurodollar futures,  used in conjunction with basis rate swaps,
are used to manage asset liability  durations related to various other crediting
arrangements emanating from other insurance businesses.  As of December 31, 1997
and  1996,  these  swap  agreements  had  the net  effect  of  shortening  asset
durations.  Variable  rates  received  on  interest  rate and  basis  rate  swap
agreements correlate with crediting rates paid on outstanding liabilities.  The
net effect of swap  payments  is settled  periodically  and  reported in income.
There is no settlement of underlying notional amounts.

Aon also  enters  into  interest  rate swap  agreements,  sells  exchange-traded
interest  rate futures and  purchases  interest  rate caps to limit its interest
expense on short-term  borrowings.  The premium that Aon pays for interest rate
caps represents the cost basis of the position until it expires or is closed.

Aon also  enters  into  interest  rate  swap and cap  agreements  and  purchases
exchange-traded  Eurodollar  and  Eurosterling  futures to limit its exposure to
decreasing short-term interest rates,  primarily relating to brokerage fiduciary
funds. The net effect of swap payments are settled  periodically and reported in
income.  There is no settlement of underlying notional amounts.  Exchange-traded
Eurodollar and Eurosterling  futures are valued and settled daily,  with amounts
reported in income when the  contract  expires.  The  commission  paid for these
futures contracts represents the cost basis of the position, until it is expired
or closed.

Exchange-traded  treasury  futures and options  are used  primarily  as a hedge
against  the  value of  Aon's  available  for sale  fixed  maturity  and  equity
investments.  Aon sells futures as well as writes 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.

In most cases,  derivatives  hedging the invested  asset  portfolio are hedging
groups of invested  assets.  The sale,  maturity or  extinguishment  of a hedged
invested  asset  within a group would not affect the  accounting  method for the
derivative.  The accounting  relating to the termination of a hedge would differ
from the company's regular accounting  practices if the hedge ceases to meet the
criteria for hedge accounting.

The  following  criteria  must be met in order for a  derivative  to qualify for
hedge accounting. The derivative must be designated as a hedge at inception and
be  consistent  with Aon's  policy  for risk  management.  The  hedged  group of
invested  assets must have a reliably  measurable fair value and changes in fair
value must have the potential to affect future earnings.

<PAGE>
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Aon performs frequent analyses to measure the degree of correlation  associated
with its  derivative  programs.  Aon assesses  the  adequacy of the  correlation
analyses  results in  determining  whether  the  derivatives  qualify for hedge
accounting.  Changes in the fair value of the  derivative  must be  expected  to
substantially  offset  changes  in the fair  value of the  designated  group of
invested assets attributable to the risk being hedged.

If the criteria for hedge accounting is not met, the resulting gain or loss from
the hedge would be realized  through the  statement of operations in the current
period.

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  remaining  life of the hedged
item. Outstanding derivatives that are hedges of items carried at fair value are
reflected  in the  financial  statements  at  fair  value  with  changes  in the
derivative  fair value  reported  as  unrealized  gains and losses  directly  in
stockholders' equity.

Notional and Other Data

The following are the notional amounts of Aon's outstanding  derivatives grouped
by the types of risks being managed:

Aon amortized $3 million in 1997, 1996 and 1995, respectively,  of net deferred
gains  relating  to  derivatives   into  income.   Realized  losses  related  to
anticipated  transactions  were immaterial for the years ended December 31, 1997
and 1996.

============================================================


As of December  31,  1997,  swaps have  maturities  ranging from January 1998 to
January  2007.  Aon receives  variable  rates based on the one month  commercial
paper and the six month  London  Interbank  Offer Rate  (LIBOR)  rate.  Aon pays
variable rates based on the three- and six-month  LIBOR rates.  Basis rate swaps
have maturities  ranging from December 2000 to August 2002 and require payments
based on the three  month LIBOR  index and  provide  for  receipts  based on the
two-year treasury rate. Other outstanding  contracts  generally have terms that
are less than one year.

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, 1997 and 1996 totaled $173
million and $154 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
September  1998.  As of  December  31,  1997 and 1996,  the  maximum  commitment
contained in these  agreements was $2.0 billion and $1.2 billion,  respectively.
Aon's credit risk relates to amounts that may be due under  recourse  provisions
that could  exceed  recorded  estimates.  At December  31,  1997 and 1996,  this
exposure was approximately $93 million and $42 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  assets  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:

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

12. CONTINGENCIES

Aon and its  subsidiaries are subject to numerous claims and lawsuits that arise
in the ordinary  course of business.  Some of these cases are being litigated in
jurisdictions  which have judicial  precedents and  evidentiary  rules which are
generally believed to favor individual  plaintiffs against corporate defendants.
The  damages  that  may  be  claimed  in  these  and  other   jurisdictions  are
substantial,  including in many instances  claims for punitive or  extraordinary
damages.  Accruals  for these  lawsuits  have been  provided  to the extent that
losses are deemed probable and are estimable.

At the time of Aon's  acquisition of A&A in January 1997, A&A was facing various
legal claims,  several of which remain ongoing. In a 1988 action,  alleging that
certain A&A  subsidiaries  placed risks with  financially  unsound  reinsurance
companies,  plaintiffs  sought $36 million in damages.  Most of the  exposure to
these   claims  was   extinguished   as  a  result  of  the  Lloyd's  of  London
Reconstruction  and Renewal  Plan.  Aon  currently  believes the loss that might
result  from the  remaining  exposure  would not be  material  to its  financial
position or results of operation.  In 1992,  the purchaser of a company A&A sold
in 1987  asserted  claims  under  the  indemnification  provision  of the  sales
agreement.  While the  possibility of  substantial  exposure  remains,  based on
current facts and circumstances,  Aon believes the possibility of material loss
resulting from these exposures is remote.

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 con-solidated financial position of Aon.

                 REPORTS BY INDEPENDENT AUDITORS AND MANAGEMENT

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,  1997  and  1996,  and  the  related
consolidated statements of income, stockholders' equity, and cash flows for each
of the three  years in the period  ended  December  31,  1997.  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, 1997 and 1996,  and the  consolidated  results of its operations
and its cash flows for each of the three years in the period ended  December 31,
1997, in conformity with generally accepted accounting principles.

REPORT BY MANAGEMENT

The  management  of  Aon  Corporation  is  responsible  for  the  integrity  and
objectivity of the financial  statements and other financial  information in the
annual report.  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,  1997,  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   those   parties   are   properly   discharging   their
responsibilities.  Both the independent  auditors and the internal auditors have
free access to the Audit  Committee,  without the  presence  of  management,  to
discuss the adequacy of internal control and to review the quality of financial
reporting.
