                                     PART I

Item 1.  Business.

A.     GENERAL DEVELOPMENT OF BUSINESS

     HSB  Group,  Inc.  (together  with  its  subsidiaries  referred  to as  the
"Company"  or "HSB"  hereinafter)  was  formed  under  the laws of the  State of
Connecticut  in 1997 to serve as the  holding  company  for The  Hartford  Steam
Boiler  Inspection  and Insurance  Company  (HSBIIC) and its  subsidiaries.  The
Hartford  Steam Boiler  Inspection  and  Insurance  Company was  chartered as an
insurance company by the Connecticut legislature in 1866.

    The Company's operations are divided into four reportable operating segments
- - Commercial insurance, Global Special Risk insurance,  Engineering Services and
Investments. The most significant business of the Company is providing insurance
against losses from accidents to boilers,  pressure vessels,  and a wide variety
of mechanical and electrical  machinery and equipment along with a high level of
inspection  and  engineering  services  aimed  at loss  prevention.  Net  earned
premiums  for the  Company's  insurance  segments in the  aggregate  were $381.9
million for 1999, which accounted for  approximately 63 percent of the Company's
revenues. See Note 10 to the Consolidated Financial Statements located in Item 8
of Part II herein for  information  on the  Company's net written and net earned
premiums over the last three years.

     The Company  conducts its business in Canada  through its  subsidiary,  The
Boiler Inspection and Insurance  Company of Canada.  Insurance for risks located
in  countries  other  than the  United  States  and  Canada  is  written  by HSB
Engineering Insurance Limited (HSB EIL).

     The  following is a summary of recent  developments  in the business of the
Company.

     The reinsurance  agreements as discussed  below  effective  January 1, 1998
between  HSBIIC,  Employers  Reinsurance  Corporation  (ERC) and Industrial Risk
Insurers (IRI) were terminated  with respect to loss or liabilities  arising out
of  occurrences  taking place on or after January 1, 2000.  As a result,  HSBIIC
will no longer  retain 85 percent of the  equipment  breakdown  insurance and 15
percent of the property insurance of the combined insurance  portfolio for risks
arising on or after January 1, 2000. The joint underwriting association that was
known as HSB Industrial  Risk Insurers  will,  from January 1, 2000, be known as
Industrial Risk Insurers.

     Concurrent with the termination of the reinsurance agreements,  HSBIIC, ERC
and IRI replaced the operating  agreement for IRI dated January 1, 1998. The new
agreement,  effective  January 1, 2000,  calls for HSBIIC to retain 0.5  percent
membership  share in IRI with the  ability to  increase  its total share up to a
maximum  of 10  percent,  at no cost,  at  HSBIIC's  option.  In  addition,  the
agreement also establishes an arrangement for HSB to perform equipment breakdown
engineering and inspection  services for clients of IRI and provides for a fixed
fronting  fee in the event that IRI  continues  to use  HSBIIC's  licenses.  See
"Participation   in  Industrial   Risk  Insurers"  on  page  13  for  additional
information.

                                       2
<PAGE>

     On January 6, 1998,  HSBIIC sold its 23.5 percent  share in IRI to ERC, one
of the world's largest  reinsurance  companies,  in accordance with a previously
announced purchase and sale agreement between ERC and IRI's twenty-three  member
insurers.  IRI is a voluntary,  unincorporated  joint  underwriting  association
which  provides  property  insurance for the class of business  known as "highly
protected  risks"  (HPR) -- larger  manufacturing,  processing,  and  industrial
businesses  that have  invested in  protection  against  loss through the use of
sprinklers and other means.  Contemporaneous with the close of the sale, IRI was
reconstituted with ERC (with a 99.5 percent share) and HSBIIC (with a .5 percent
share) as the sole members. Under the 1998 agreements, HSBIIC wrote the business
for the reconstituted IRI (which was renamed HSB Industrial Risk Insurers) using
its  insurance  licenses and provided  certain  other  management  and technical
services. In addition,  through various reinsurance agreements with ERC and IRI,
HSBIIC transferred its manufacturing book of business to IRI and retained 85% of
the  equipment  breakdown  insurance  and 15% of the  property  insurance of the
HSBIIC/IRI combined portfolio.

     On  December  31,  1997,  to  support  the  Company's  role with HSB IRI, a
business trust formed by HSB sold $300 million of 20-year, 7 percent Convertible
Capital  Securities  in a private  placement  to ERC, of which $250  million was
contributed by the Company to HSBIIC.  The capital  securities  are  convertible
into HSB common stock, at any time, subject to regulatory approval.  See Note 13
to the Consolidated Financial Statements located in Item 8 of Part II herein for
more information on this transaction.

     Effective  July 1, 1998,  HSBIIC  completed an  acquisition of the monoline
boiler and machinery  business and the ASME inspection  services,  which certify
boiler  and  pressure  vessel  compliance  with the codes and  standards  of the
American Society of Mechanical  Engineers,  of the Kemper  Insurance  Companies.
Kemper and HSBIIC also completed an agreement for HSBIIC to reinsure  boiler and
machinery coverage included as part of Kemper's commercial package policies.

     The Company also offers  professional  scientific and technical  consulting
services for industry and  government  on a world-wide  basis  through  HSBIIC's
Engineering   Department  and  its  engineering   subsidiaries.   In  1999,  net
engineering   services  revenues  were  $119.6  million,   which  accounted  for
approximately 19.7 percent of the Company's revenues.

     On January 2, 1998, the Company  exercised its option to put its 40 percent
share in Radian  International  LLC (Radian LLC) to The Dow Chemical Company for
approximately  $129 million,  net of expenses.  Radian LLC was formed in January
1996  as a  joint  venture  with  Dow  to  provide  environmental,  engineering,
information  technology,  remediation and strategic chemical management services
to industries and  governments  world-wide.  In connection with the formation of
the new company, the Company contributed  substantially all of the assets of its
wholly-owned subsidiary, Radian Corporation to Radian LLC. The results of Radian
LLC were classified as discontinued  operations  following  ratification in July
1997 by the Board of Directors of management's decision to exercise its put. The
Company's share of Radian LLC's losses  incurred  subsequent to such decision of
approximately  $6.6 million after-tax was deferred until the closing of the sale
on January 2, 1998, at which time an estimated after-tax gain of

                                       3
<PAGE>


$30.3 million,  net of deferred losses, was realized.  In 1996 and prior to July
1997, the Company's share of the joint venture's results were recorded as equity
in Radian.

     Recently  the  Company  has  been  focusing  on   identifying   acquisition
candidates in the niche  engineering  management  consulting  service  business,
primarily  in  process  or  energy  related  industries,  in order to  expand or
complement its engineering service capabilities.  The Company does not currently
anticipate  that any single  acquisition  within the next twelve  months will be
material to the operations or financial position of the Company,  however,  this
does not rule out the possibility.

     In  July  1999,  HSBIIC  acquired  Structural  Integrity  Associates,  Inc.
(Structural)  based  in  San  Jose,  California.  Structural  is an  engineering
consulting and inspection  services firm  specializing in the analysis,  control
and  prevention  of  structural  and equipment  failures.  Its services  include
inspection and condition  assessment and monitoring and remaining life analysis,
repair,  remediation  and  total  risk  management  of  critical  equipment  and
structures. In April 1998, HSB acquired Solomon Associates,  Inc. (SAI) based in
Dallas,  Texas. SAI is an engineering  management  consulting firm that provides
comparative performance benchmarking consulting to the refining,  petro-chemical
and  power  generation  industries.  During  1997,  the  Company  completed  the
acquisition of Haughton Engineering Services Limited of England. Haughton offers
a wide  range of  inspection  services  in the  United  Kingdom  to help  ensure
compliance  with regulatory  codes.  During 1997, the Company also acquired a 51
percent interest in Integrated Process  Technologies LLC (IPT). IPT measures and
manages  facility costs and service  performance on an outsource basis for large
businesses with geographically distributed locations.

     The  Company  is a  multi-national  company  operating  primarily  in North
American, European, and Asian markets. Currently, the Company's principal market
for its insurance and engineering  services is the United States.  However,  the
Company  does  desire  to  become a  stronger  competitor  in the  international
machinery  breakdown  insurance and related  engineering  services markets as it
believes that there is significant  opportunity for profitable  growth overseas.
In 1999, the revenues and pre-tax income  associated with operations  outside of
the United States were approximately 13.2 percent and 9.5 percent, respectively.
Identifiable  assets associated with operations outside of the United States are
approximately 19.5 percent of the consolidated  amount. See Note 1 and Note 5 to
the Consolidated  Financial  Statements  located in Item 8 of Part II herein for
more financial data based on geographic location and business segments.


B.     PRODUCTS AND SERVICES

Insurance

     Equipment  breakdown  insurance  provides  for the  indemnification  of the
policyholder  for financial  loss  resulting  from  destruction  or damage to an
insured boiler,  pressure vessel, or other item of machinery or equipment caused
by an accident.  This  financial  loss can include the cost

                                       4
<PAGE>

to repair or replace  the  damaged  equipment  (property  damage),  and  product
spoilage,   lost  profits  and   expenses  to  avert  lost   profits   (business
interruption) stemming from an accident.

     The  Company   distinguishes  itself  from  other  insurance  suppliers  by
providing  a  high  level  of  loss  prevention,   failure  analysis  and  other
engineering  services with the insurance  product.  This heavy  emphasis on loss
prevention  historically has had the dual effect of increasing  underwriting and
inspection expenses, while reducing loss and loss adjustment expenses.

     An important  ancillary benefit for the policyholder is that the inspection
performed by the  Company's  inspector on a boiler,  pressure  vessel,  or other
piece of equipment,  as part of the insurance  process,  is normally accepted by
state and other  regulatory  jurisdictions  for  their  certification  purposes.
Without  a  certificate  of  inspection  by the  insurance  carrier  or  another
inspection agency, policyholders cannot legally operate many types of equipment.

     The  Company  also  writes  all risk  property  insurance  for  risks  with
significant  machinery  and  equipment  exposures,   in  addition  to  its  more
traditional  boiler and  machinery  products.  The all risk line is  marketed to
customers with equipment and machinery  exposures,  such as electric  utilities,
where  sophisticated  engineering  services are important to loss prevention and
control.  These  customers are offered  technical  services such as computerized
evaluations  of fire  protection  systems in  addition to fire  inspections  and
boiler and  machinery  inspections.  The Company  also writes all risk  coverage
specifically tailored for data processing systems.

Engineering Services

     HSBIIC's Engineering Services division provides quality assurance services,
inspections  to code standards of the American  Society of Mechanical  Engineers
(ASME) and other organizations, ISO certification and registration services and,
using its proprietary  technologies  and databases,  provides other  specialized
consulting,  condition monitoring,  benchmarking and inspection services related
to the design and  applications  of boilers,  pressure  vessels,  and many other
types  of  equipment  for  domestic  and  foreign  equipment  manufacturers  and
operators.  HSBIIC is the largest Authorized Inspection Agency for ASME codes in
the  world.  The  Engineering   Services   division  also  offers  training  and
educational  services  related to these areas.  In addition the Company has been
developing  and  expanding  its  services  to  respond to the  growing  trend to
outsource the management and maintenance of property, plant and equipment.

    Aside from  HSBIIC,  the  Company's  engineering  affiliates  include  HSB
Reliability  Technologies  Corp. (HSB RT), HSB Professional  Loss Control,  Inc.
(HSB PLC),  Integrated Process Technologies LLC (IPT), Solomon Associates,  Inc.
(SAI),  Structural  Integrity  Associates,  Inc.  (Structural)  and HSB Haughton
Engineering Services Limited (Haughton).  HSB RT maintains an extensive database
on equipment  maintenance and reliability  and provides  preventive  maintenance
consulting  services and programs to a wide range of businesses and  industries.
Such  services  and  programs  are  designed  to  increase  production,

                                       5
<PAGE>


reduce maintenance, energy and spare parts inventory costs, and extend equipment
life. HSB PLC is a fire protection consulting and engineering firm. Its services
include inspections,  hazards analysis and risk assessment,  engineering design,
code consulting,  research and testing, and training. Structural, SAI, Haughton,
and  Integrated  Process  Technologies,  in which the  Company  holds a majority
interest, are described on page 4.

C.     COMPETITION

Insurance

     The Company is the largest writer of equipment breakdown insurance in North
America and is establishing a significant presence in the engineering  insurance
market outside of North America.  Based on net premiums  written reported in the
1999 edition of Best's Aggregates and Averages,  the Company has approximately a
39 percent  market share and no other single  company has more than a 10 percent
market share of the domestic  equipment  breakdown  market.  The Factory  Mutual
Insurance Company has a market share of approximately 18 percent.

     In general,  the  insurance  market is  influenced  by the total  insurance
capacity  available  based on  policyholder  surplus.  Over the last few  years,
global  capacity to accept  risk has grown as new  insurers  enter the  property
casualty  market and new  financial  products  have been  designed to securitize
catastrophe  risks.  In  addition  to  available  capacity,  competition  in the
equipment  breakdown  insurance  market  is based on price  and  service  to the
insured.  Service includes maintaining customer  relationships,  engineering and
loss  prevention  activities,  and claims  settlement.  The  Company  prices its
product  competitively in the marketplace,  but primarily competes by offering a
high level of service, not by offering the lowest-priced product.

     Competition in the equipment  breakdown  insurance  market,  as well as the
property/casualty market in general, has intensified in recent years as a result
of  continuing  restructuring  and  consolidation  in  the  insurance  industry.
However,  because the Company  primarily  underwrites risks which require unique
engineering  expertise and jurisdictionally  mandated  inspections,  the Company
believes that its products and services will continue to be competitive.

Engineering Services

     The Company provides a wide range of engineering, consulting and inspection
services as  described  on page 5. For most of these  services  it has  numerous
competitors,  some of whom are much larger and have greater financial  resources
than the Company.

     Competition  in these  areas is based on price  and on the  qualifications,
experience  and  availability  of the  individuals  who  perform  the work.  The
Company's force of inspectors,  engineers,  and technicians is spread throughout
the world.  Ongoing  training  programs

                                       6
<PAGE>

ensure  that the  Company's  inspectors,  engineers,  and  technicians  are kept
up-to-date on the latest engineering and technical developments.

D.     MARKETING

Insurance

     The Company's various functional operations are aligned to focus on its two
principal  customer  groups,  commercial  risks and global  special  risks.  The
Company  believes that this  organizational  structure  allows it to service its
customers more  effectively  and  efficiently  and at the same time to be a more
aggressive and flexible competitor.

     Currently, the Company's principal market for its insurance business is the
United States.  In 1999, 90 percent of its net written premiums related to risks
located  in the United  States.  Of the  direct  premiums  written in the United
States in 1999 (gross premiums less return premiums and cancellations, excluding
reinsurance  assumed  and  before  deducting  reinsurance  ceded),  less than 10
percent was written in any one state. With the exception of California, Florida,
New York,  Pennsylvania and Texas, no state accounted for more than 5 percent of
such premiums.

     The Company has contracts with independent  insurance agencies in all fifty
states, the District of Columbia,  Puerto Rico and Canada. These agencies market
the  Company's  direct  insurance to its small and medium  commercial  accounts.
Personal contact with these independent insurance agents is accomplished through
the Company's  field sales force which  operates out of various  branch  offices
across the  country  and in Canada.  It is the  Company's  policy in  appointing
agents  to be  selective,  seeking  to  maintain  and  strengthen  its  existing
relationships  and to develop  relationships  with new agents  whom the  Company
believes  will become a continuing  source of profitable  business.  The Company
periodically  reviews its agency contracts and selectively reduces them in order
to retain only those agents who  consistently  produce certain minimum levels of
business for the Company.

     Large, engineering-intensive U.S. and international accounts, most of which
comprise the Global Special Risk segment, are primarily marketed and serviced by
account teams comprised of underwriting, marketing, engineering and claims staff
who have specialized knowledge of particular customer industries. U.S. customers
are serviced primarily by HSBIIC.  Canadian customers are serviced by The Boiler
Inspection and Insurance Company of Canada.  Overseas  customers are serviced by
HSB Engineering  Insurance Limited,  based in London, with additional offices in
Hong Kong, China, Malaysia, Australia, Miami, Spain, Korea and South Africa.

     Additionally,  the  Company  markets  its  insurance  products  through the
distribution  channels of the companies  which it reinsures.  See  discussion of
reinsurance assumed on page 11.

                                       7
<PAGE>

     Large account  business is brokered  through a small number of brokers as a
result of the significant  consolidation of the international brokerage business
in the late 1990s.  For 1999,  approximately  26 percent of the Company's  gross
written  premium,  which included HSB Industrial Risk Insurers,  was produced by
J&H Marsh & McLennan and Sedgwick Group.

     No other  insured  or  broker  accounts  for more  than 10  percent  of the
consolidated total revenues of the Company.

Engineering Services

     The  Company's  engineering  services  are  marketed  in a variety of ways.
Customized services related to loss prevention,  failure analysis, and equipment
testing are generally  sold in conjunction  with the insurance  contract but are
also available separately. Most other engineering services are marketed on a bid
or proposal basis. While such business is usually price sensitive,  the exacting
standards  and  requirements  set by  industry  and  government  for most of the
services offered by the Company tend to diminish that effect.

     Engineering  services  are  marketed  and  serviced  primarily by personnel
located in the Company's various domestic and international offices.

     While the primary market for engineering services continues to be the U.S.,
the Company has been focusing on expanding its international business, primarily
in Europe,  the Pacific Rim and certain countries in South America as demand for
engineering  services is  expected to grow at a faster rate in these  developing
regions than in the U.S.

     No engineering  services  customer accounts for more than 10 percent of the
Company's consolidated total revenues.

E.     REGULATION

Insurance

     The Company's  domestic insurance  subsidiaries'  operations are subject to
regulation  throughout  the United  States.  Various  aspects  of the  insurance
operations are regulated,  including the type and amount of business that can be
written, the price that can be charged for particular forms of coverage,  policy
forms,  trade and claim settlement  practices,  reserve  requirements and agency
appointments.  Regulations  also  extend to the form and  content  of  financial
statements filed with such regulatory authorities, the type and concentration of
permitted  investments  for insurers,  and the extent and nature of transactions
between  members of a holding  company  system,  including  dividends  involving
insurers.  In general,  such  transactions must be on fair and reasonable terms,
and in some cases,  prior  regulatory  approval is required.  In addition,  many
states require advance  notification,  and in the case of domiciliary  insurers,
require prior  approval of any  acquisition  of control  (generally  presumed to
exist  in the  case of a 10% or  more  ownership  of  voting  securities)  of an

                                       8
<PAGE>


insurance company. Such laws, while intended to protect policyholder  interests,
may delay or prevent  certain  transactions  effecting a change in control of an
insurer.

     The nature and extent of regulations pertaining to the business the Company
writes  outside  of the U.S.  varies  considerably.  Regulations  cover  various
financial and  operational  areas,  including such matters as amount and type of
reserves,  currency,  policy  language,  repatriation  of assets and  compulsory
cessions of reinsurance.

     In the United States, the National  Association of Insurance  Commissioners
(NAIC) has adopted risk-based capital (RBC) requirements  applicable to property
and casualty insurers.  The RBC formula establishes a required statutory surplus
level for an insurer based on the risks inherent in its overall operations which
are  identified  as  underwriting  risk,  invested  asset risk,  credit risk and
off-balance  sheet risk. The law provides for regulatory  responses ranging from
requiring a plan of corrective  action to placing the insurer  under  regulatory
control for insurers whose surplus is below the prescribed RBC target.  HSBIIC's
adjusted  capital  significantly  exceeded the authorized  control level RBC for
1999.

     NAIC Insurance Regulatory  Information System (IRIS) ratios are part of the
solvency  impairment  early warning  system of the NAIC.  They consist of twelve
categories of financial data with defined acceptable ranges for each.  Companies
with ratios outside of the  acceptable  ranges are selected for closer review by
regulators. HSBIIC's IRIS ratios were within acceptable ranges for 1999 with the
exception of the change in surplus  ratio.  This ratio exceeded the normal range
for surplus  increases or decreases due to $152.7  million of dividends  paid by
HSBIIC to HSB Group,  Inc., net unrealized losses of $92.9 million primarily due
to a decrease in the carrying value of its insurance  subsidiaries and a decline
in the  value  of the  fixed  income  portfolio,  and  other  statutory  surplus
adjustments of $18.0 million, offset by $80.0 million of net income.

     The Company's insurance subsidiaries' operations are subject to examination
by  insurance  regulators  at regular  intervals.  The most  recently  concluded
insurance  examination for HSBIIC was conducted for the years 1995 - 1998 by the
Connecticut Insurance Department,  the HSBIIC's domestic regulator.  No material
findings or  adjustments  were included in the final report of the  examination.
Similar  regulatory  procedures  govern the  Company's  other U.S.  and  foreign
insurance subsidiaries.

     Insurance  guaranty fund laws exist in all states which subject insurers to
assessments  up to  prescribed  limits  for  certain  obligations  of  insolvent
insurers to their  policyholders  and  claimants.  The Company is  permitted  to
recover a portion of these  assessments  through  premium tax offsets and policy
surcharges.

     See Note 6 to the Consolidated  Financial  Statements  located in Item 8 of
Part II herein for additional information on statutory reporting.

     As discussed earlier,  the Company's  insureds receive,  in addition to the

order for the Company's inspectors to perform these mandated  inspections,  they
must be commissioned. Commissioning is conducted by the National Board of Boiler
and Pressure Vessel Inspectors and the various state jurisdictional authorities.
The  majority of the  Company's  inspectors  are  commissioned,  and the Company
believes that it has an adequate  number of  commissioned  inspectors to conduct
its business affairs.

Engineering Services

     A  portion  of  the  Company's  engineering  services  revenue  comes  from
certifying that boilers and pressure vessels are being constructed  according to
standards adopted by the American Society of Mechanical  Engineers  (ASME).  The
commission  that authorizes  inspectors to conduct  insurance  inspections  also
authorizes  them to perform ASME Code  inspections.  The Company  performs other
certification  and  inspection   services  which  are  governed  by  established
standards, such as ISO 9000.

Other

     The Company and members of its professional and technical staff are subject
to a variety of other state, local and foreign licensing and permit requirements
and other laws generally applicable to corporations and businesses.

F.     INSURANCE OPERATIONS

Policies

     Pricing for the  Company's  insurance  policies is based upon the rates the
Company has developed for use with its various products.  In many  jurisdictions
in which the Company  does  business,  such rates,  as well as the policy  forms
themselves,  must be approved by the jurisdiction's  insurance regulator.  Rates
for the  Company's  products are  developed  based upon  estimated  claim costs,
expenses  related to the acquisition and servicing of the business,  engineering
expenses and a profit component.

     Coverages  for  unique  risks  are  judgment-rated,   taking  into  account
deductibles,  the  condition of the insured's  equipment,  loss  prevention  and
maintenance programs of the insured, and other factors.

     Policies are normally written for a term of one year. Most of the Company's
policies  provide  coverage for property  damage and  business  interruption  to
insured  property  (including  buildings and structures  under the Company's all
risk policy) resulting from covered perils. Property insured under the Company's
equipment breakdown policies includes such equipment as steam boilers, hot water
boilers,  pressure vessels,  refrigerating and air conditioning systems, motors,
generators,  compressors,  pumps,  engines,  fans, blowers, gear sets, turbines,
transformers, electrical switch gear, data processing and business equipment and
a wide variety of production and processing equipment.

                                       10
<PAGE>

     The  Company's  policy with  respect to the business it  underwrites  is to
generally  manage its risks to probable  maximum  losses (PMLs) not in excess of
$50 million and maximum foreseeable losses (MFLs) not in excess of $100 million.
The  Company's  current  reinsurance  program  generally  limits  the  Company's
retention  on any one  loss to $1  million,  with  potentially  higher  per risk
retentions  dependent on aggregate losses  experienced by the Company during the
reinsurance period.


Reinsurance Assumed

     The  predominant  practice in the insurance  industry is to combine several
types of insurance  coverages into one policy  referred to as a package  policy.
The  Company  has  reinsurance  agreements  with  approximately  200  multi-line
insurance companies to reach the small to mid-sized customers that purchase such
package  policies.  This  business  primarily  focuses  on small  and  mid-sized
commercial  customers and it offers a significant  opportunity for growth by the
Company because,  based on Company  estimates,  equipment  breakdown coverage is
only provided  currently to less than 15 percent of the over 10 million  insured
companies and institutions in the United States.

     Under the reinsurance  agreements,  the Company's  reinsured  companies may
include equipment  breakdown exposures in their multi-peril  policies,  and such
risks will be assumed by the Company  under the terms of the  agreements.  These
plans generally  provide that the Company will assume 100 percent of each boiler
and machinery risk, subject to the capacity specified in the agreement, and will
receive the entire equipment  breakdown  premium except for a ceding  commission
which will be retained by the reinsured  company for  commissions  to agents and
brokers, premium taxes and handling expenses.

     Although the Company  assumes the role of  reinsurer,  it continues to have
selling and underwriting  responsibilities  as well as involvement in inspecting
and claims  adjusting.  In effect,  the Company becomes the equipment  breakdown
insurance  department of the reinsured company and provides equipment  breakdown
underwriting  (that is, the  examination and evaluation of the risk based on its
engineering  judgments),  claims and engineering  services as if it were part of
that  organization.  Traditionally,  as part of the  underwriting  process,  the
Company retains the right to decline or restrict  coverage in the same manner as
it does for its own  business.  The  Company  also writes a  simplified  program
(referred  to as  ReSource)  under which a reinsured  company  agrees to include
equipment  breakdown  insurance  on a  portfolio  of accounts  meeting  specific
underwriting  guidelines and occupancy  parameters,  which the Company agrees to
reinsure for equipment breakdown losses.

     The  insurance  industry,  in  general,  continues  to undergo  significant
restructuring and consolidation. A considerable amount of merger and acquisition
activity  has  occurred  over the last  several  years  and,  with the advent of
financial services reform, more contraction is possible in the future. Depending
on the specific companies involved in these activities and other market factors,
the level of  reinsured  business  the Company  assumes in the future  under the
arrangements described above could be impacted.

                                       11
<PAGE>

     The Company also assumes reinsurance, primarily on a facultative basis, for
certain large risks and several insurance pools.

     The written premium  generated through  reinsurance  assumed totaled $363.3
million in 1999, representing  approximately 46.6 percent of the Company's gross
written premium.

Reinsurance Ceded

     As a property carrier, the Company is subject to losses that may arise from
catastrophic  events.  The Company  participates in various  facultative,  quota
share  and  excess  of  loss  reinsurance  agreements  to  limit  its  exposure,
particularly  to  catastrophic  losses  and  high  risk  lines,  and to  provide
additional  capacity to write business.  The Company evaluates its exposures and
reinsurance  needs  annually to  implement a program that  corresponds  with the
level of exposure it is willing to retain.  Under the Company's  current  treaty
reinsurance  program, its maximum retention on any one risk is generally limited
to $1  million,  with  potentially  higher  per  risk  retentions  depending  on
aggregate  losses  experienced  by the Company  during the  reinsurance  program
period.  In addition,  the Company uses facultative  reinsurance on certain high
exposure risks and has catastrophe  reinsurance for aggregate net losses greater
than $15 million.

     The  Company   utilizes   well-capitalized   domestic   and   international
reinsurance  companies and syndicates for its  reinsurance  program and monitors
their  financial  condition on an ongoing  basis.  For  reinsurers  that are not
accredited in their state of domicile, the Company typically requires collateral
for reinsurance  recoverable from such carriers.  In the unlikely event that the
Company's  reinsurers  are unable to meet their  obligations,  the Company would
continue  to have  primary  liability  to  policyholders  for  losses  incurred.
Uncollectible  reinsurance  recoverables  have not had,  and are not expected by
management to have in the future,  a material adverse effect on the consolidated
results of operations or financial  position of the Company.  The Company is not
party to any contracts  that do not comply with the risk transfer  provisions of
SFAS 113  "Accounting  and  Reporting  for  Reinsurance  of  Short-Duration  and
Long-Duration Contracts".

     For  additional  information  on  reinsurance,  see  Notes 10 and 11 to the
Consolidated Financial Statements located in Item 8 of Part II herein.

Pools and Joint Underwriting Associations

     With the exception of HSB  Industrial  Risk Insurers as described on page 2
and discussed below, the Company does not participate to any significant  degree
in voluntary  reinsurance pools of other insurance companies because the Company
generally  chooses to insure only those risks which it has  inspected or has the
right to inspect.  From time to time,  the Company is required to participate in
certain joint  underwriting  associations which provide insurance for particular
classes of insureds when insurance in the voluntary market is unavailable.

                                       12

Participation in Industrial Risk Insurers

     Industrial  Risk  Insurers  (IRI)  is an  unincorporated,  voluntary  joint
underwriting  association  that  provides  property  insurance  for the class of
business known as "highly protected risks" for larger manufacturing,  processing
and industrial businesses which have invested in protection against loss through
the use of sprinklers and other means. As part of the arrangement with Employers
Reinsurance  Corporation  (ERC)  effective  January  1,  1998  (see "A.  GENERAL
DEVELOPMENT  OF  BUSINESS")  HSBIIC wrote the insurance in 1999 and 1998 for IRI
(which did  business  under the name HSB  Industrial  Risk  Insurers)  using its
insurance  licenses and provided  certain other services.  In addition,  through
various  quota  share   reinsurance   agreements   with  Employers   Reinsurance
Corporation and HSB IRI, HSBIIC  transferred its manufacturing  book of business
to HSB IRI and retained 85 percent of the equipment  breakdown  insurance and 15
percent of the property insurance of the combined insurance portfolio.

     In 1998 and 1999,  HSBIIC's  membership interest in HSB IRI was .5 percent.
In 1997 and 1996,  HSBIIC's  membership interest was 23.5 percent and 14 percent
respectively.  In 1996 and prior the shares were .5 percent.  As discussed above
(see "A. GENERAL DEVELOPMENT OF BUSINESS") the reinsurance  agreements effective
January 1, 1998 between HSBIIC, ERC and IRI were terminated with respect to loss
or liabilities  arising out of  occurrences  taking place on or after January 1,
2000. Net earned premium  attributable  to the agreements  with ERC and HSB IRI,
prior to the placement of reinsurance by the Company for its own account, was 11
percent of the Company's total consolidated revenues for 1999 and 15 percent for
1998. Ceding commissions,  which are netted out of expenses,  were 16 percent of
consolidated revenues for 1999 and 11 percent for 1998.

Claims and Claim Adjustment

     Essentially  all claims  under the  Company's  policies  of  insurance  are
handled by the  Company's  own claims  handlers.  Management  believes  that the
Company's  handlers  are  better  able  to  make  the  connection  between  loss
prevention and loss control.  The Company employs claims handlers in its various
offices  throughout the country,  Canada and the U.K. Claims  handlers,  in many
cases, are assigned to particular  customer groups in order to apply specialized
industry knowledge to the adjustment of claims.

     Claims  and  adjustment  expense  reserves  comprise  one  of  the  largest
liabilities of the Company.  Reserves are  established  to reflect  estimates of
total losses and loss  adjustment  expenses  that will  ultimately be paid under
direct  and  assumed  insurance  contracts.  Loss  reserves  include  claims and
adjustment  expenses on claims that have been reported but not settled and those
that have been incurred but not yet  reported.  Loss reserve  estimates  reflect
such variables as past loss  experience and inflation.  In addition,  due to the
nature of much of the  coverages,  complex  engineering  judgments are involved.
Subjective  judgments are an integral  component of the loss reserving  process,
due to the  nature  of  the  variables  involved.  Previously  established  loss
reserves are regularly adjusted as loss experience  develops and new information
becomes available.  Adjustments to previously established

                                       13
<PAGE>

reserves are  reflected in the  financial  statements in the period in which the
estimates are changed.

     The normal  turnaround time in paying small claims is less than six months.
The vast  majority  of claims  are  settled  within one year and very few remain
unsettled  two years after the loss occurs.  This pattern is somewhat  skewed in
terms of claim  dollars (as noted in the schedule on pages 17 - 18) as it is the
larger   claims   that  often   take   longer  to   adjust.   Compared   to  the
property/casualty  industry  as a whole,  the  Company  has a very  "short-tail"
settlement  period.  The Company's claims expenses are based on estimates of the
current  costs of  replacing  productive  capacity.  The Company does not employ
discounting  techniques  in  establishing   liabilities  for  claims  and  claim
adjustment expenses.

     For those relatively few claims involving litigation, the Company uses both
its in-house law department and outside counsel, depending on the issues, costs,
and staffing requirements.

    The following  table provides a  reconciliation  of the beginning and ending
reserves  for net  claims  and claim  adjustment  expenses  for the years  ended
December 31, 1999, 1998 and 1997.

     The loss ratio  improved  0.8  percentage  points in 1999 from  1998.  This
improvement was primarily attributable to increased use of reinsurance. The 1999
results were impacted by $10 million of domestic  weather-related events and the
Taiwan  earthquake as well as $10 million in losses related to medical equipment
insurance contracts.  These insurance contracts  represented less than 1 percent
of the Company's  revenues.  The loss ratio  decreased 0.2 percentage  points in
1998 as  compared  to 1997.  Loss  results in 1998 were

                                       14

impacted by severe ice storms in Canada, as well as a few significant  losses in
our other  international  businesses.  Prior year loss development in 1999, 1998
and 1997 added 0.1, 2.8 and 1.7 percentage  points to the respective loss ratio.

     The net  deficiencies  in  1990,  1991 and 1992  were  attributable  to the
settlement of certain large losses for which the Company initially determined it
would not have  liability,  the settlement of some  outstanding  claims for more
than was originally  anticipated,  unusually late notice of loss provided by the
insured for several large losses,  and reserves  established for losses on which
the coverage was being  contested.  The 1995 net redundancy was  attributable to
favorable claim development in the Company's foreign operations.

     The adverse development primarily resulted from the decision rendered under
an  arbitration  proceeding  for a  claim  occurring  in  1992,  adverse  claims
experience in  international  operations  primarily  occurring in accident years
1997 and 1998, and the settlement of some large outstanding claims for more than
originally anticipated.

     The growth in the gross  liability for unpaid claims and claims  adjustment
expenses from 1995 forward reflects the Company's changing  participation in IRI
which was .5 percent through December 1, 1995, 14 percent effective  December 1,
1995, 23.5 percent effective December 1, 1996 as well as the HSB IRI arrangement
effective January 1, 1998. See page 2 for details.

G.     INVESTMENTS

     Income from the Company's investment portfolio contributes significantly to
earnings.  Each year there is a significant  net inflow of cash from  insurance,
engineering  services and investment  operations  into the Company's  investment
portfolio.  In addition,  cash flow is affected by the normal  maturity of fixed
income  investments,  financing  activities  and the purchase and sale of equity
securities.

     The  Company's  strategy  continues  to be to maximize  total return on the
investment  portfolio  through  investment  income  and  capital   appreciation.
Investment  strategies  for any given year are  developed  based on many factors
including  operational  results,  tax  implications,   regulatory  requirements,
interest  rates,   dividends  to  stockholders   and  market   conditions.   The
fluctuations  in income from  investment  operations from 1995 through 1997 were
largely driven by the amount of realized gains  generated in each of such years.
In 1995 the Company curtailed its realized gains in order to take advantage of a
strongly  performing market and to build statutory surplus.  In 1996 the Company
continued to build statutory surplus,  however,  high valuations towards the end
of the year  caused the  Company to realize  gains.  Realized  investment  gains
increased in 1997 over 1996 as the Company  managed its  portfolio to respond to
changing market  conditions and tax planning  opportunities,  and as a result of
calls of fixed income and convertible  securities.  Realized investment gains in
1998 were  significantly  impacted by call premiums on fixed income  instruments
and sales of certain  convertible  securities  and common  stocks in response to
market conditions.  Realized investment gains increased $15.2 million in 1999 as
a result of repositioning  the investment  portfolio due to market  fluctuations
and to keep the  absolute  amount of common  equities  from  exceeding a certain
targeted  percentage  of the  Company's  GAAP  capital.  During 1999 bond yields
continued  to move up,  the  impact  of which  has  caused  a  reduction  in the
Company's   unrealized  gains  with  respect  to  fixed  income   securities  by
approximately $64.5 million.

     Net  investment  income  increased 11.8 percent in 1996 due to an increased
level of investable  assets and to a lesser extent by dividend  increases on the
Company's  common stock  investments.  Net investment  income for 1997 increased
13.9 percent  compared to 1996.  The increase is  attributable  to calls of high
yielding  preferred stocks early in the year the proceeds of which were invested
in fully taxable  securities,  and more investable funds as the Company invested
the proceeds from its capital  securities  issued in the second half of 1997. In
1998 net investment income increased  significantly due to the investment of the
capital  securities  proceeds and from the January  1998 sales of the  Company's
interests in IRI and Radian  International  LLC. Net investment  income for 1999
remained flat compared to 1998.

     The significant  increase in statutory  surplus of HSBIIC for 1997 resulted
from a  contribution  to capital of $250 million of the $300 million in proceeds
received by the Company from the sale of its convertible  capital  securities to
Employers Reinsurance  Corporation on December 31, 1997. The increase in surplus
for 1998 resulted  from the January 1998 sales of HSBIIC's  interests in IRI and
Radian  International  LLC. The decrease in surplus for 1999 primarily  resulted
from  $152.7  million  of  dividends  paid by HSBIIC  to HSB  Group,  Inc.,  net
unrealized  losses of $92.9 million  primarily due to a decrease in the carrying
value of its  insurance  subsidiaries  and a  decline  in the value of the fixed
income  portfolio,  and other  statutory  surplus  adjustments of $18.0 million,
offset by $80.0 million of net income.

     In December 1996, HSBIIC entered into three "zero cost collar" contracts to
mitigate the effects of market risk on its U.S.  common stock  portfolio  (which
for management
                                       19
<PAGE>

purposes  included  certain  convertible  preferreds).  In the fourth quarter of
1997,  HSBIIC  settled all of its  outstanding  contracts  resulting in realized
losses  of  $30.7  million  for  the  year,  all of  which  were  offset  by and
represented portfolio  appreciation and returns that were realized. In 1997, the
Company's U.S. common stock portfolio  experienced a total return of $57 million
(which included price  appreciation of approximately $54 million) since December
31, 1996,  and had a price movement  correlation  with the S&P 500 Index well in
excess of 80 percent.

      The Company's  investment  portfolio  consists of high-grade  domestic and
foreign  investments.  Excluding short-term  investments,  HSB's investments are
primarily  comprised of publicly traded,  highly liquid securities.  At December
31, 1999, the Company had  approximately  52.9 percent of its invested assets in
fixed  maturities  as compared to 53.6 percent at year-end  1998.  In the period
1991-1996 the Company gradually reduced its investments in common stocks as part
of its overall capital management strategy. At year-end 1999, the carrying value
of the equity securities  portfolio  represented 41.3 percent of invested assets
compared to 40.6 percent at year-end 1998.

     The Company  does not engage in  cash-flow  underwriting;  it seeks to have
underwriting  profit  each  year.  None  of the  Company's  claim  reserves  are
discounted as most claims settle, on average,  within one year.  Therefore,  the
Company  does not use  duration  measurements  in  managing  its  interest  rate
exposure.  Instead,  the Company  manages its  portfolio  on a segmented  basis.
Approximately  $300  million  (cost  basis)  of the  Company's  invested  assets
(comprised of perpetual and redeemable preferred stocks and corporate bonds) are
utilized to provide interest coverage and potential principal repayment over the
life of the  convertible  capital  securities  issued on December 31, 1997.  The
remainder  of  the  Company's  invested  assets,  exclusive  of  cash  and  cash
equivalents,  short-term  securities  and common  stocks are invested to provide
income for the  future.  There are three  portfolio  areas with quite  different
maturity/call   characteristics.   The   portfolio  of   traditional   bonds  of
approximately $245 million has an average life of 22 years, with over 50 percent
of that  portfolio  callable in less than ten years.  The sinking fund preferred
portfolio  of $43 million,  based on expected  calls,  has an estimated  life of
three years. The $52 million adjustable rate preferred stock portfolio, based on
expected calls, has an estimated life of five years.

     The Company believes the expected cash flows from the Company's operations,
maturities  and calls are  adequate  to enable  the  Company  to  respond to the
previously  discussed  parameters  that  impact  its  investment  strategy.  See
"Investment   Operations"  in  the  Management's   Discussion  and  Analysis  of
Consolidated Financial Condition and Results of Operations located in Item 7 and
Note 7 to  Consolidated  Financial  Statements  in Item 8 of Part II herein  for
additional information.

securities on December 31, 1997.

** For the  calculation of Annualized  Rate of Return "Cash and Invested  Assets
Less Borrowed  Money"  includes the $300 million in proceeds in the beginning of
the year.

(1) Net investment income excludes  realized  investment gains and is reduced by
investment expenses, but is before the deduction for income taxes.

(2) The rates of return on  investments  shown  above  have been  determined  in
accordance  with rules  prescribed  by the  National  Association  of  Insurance
Commissioners. These rates have been determined by the following formula:

                                  2I
                                  --
                               A + B - I

I is equal to net investment income, before taxes, earned on investment assets.

A+B is equal to the sum of the beginning and end of the year amounts shown under
"Cash and Invested Assets,  Less Borrowed Money".  The after tax rates of return
are computed in the same manner,  but net investment income is reduced by income
taxes.

Item 5.  Market for Registrant's Common Equity and Related
         Stockholder Matters.

     The Company's  common stock is traded on the New York Stock  Exchange under
the symbol HSB.  As of  February  15,  2000,  the  Company had 4,826  holders of
record.

     Dividends  paid by The  Hartford  Steam  Boiler  Inspection  and  Insurance
Company,  HSB  Group's  principal  subsidiary,  are  limited by state  insurance
regulations.  Approval from the Connecticut  Insurance  Commissioner is required
for dividend  distributions  within a twelve-month period which would exceed the
greater of (i) 10 percent of an insurer's  statutory  surplus or (ii) net income
calculated as of the December 31st last preceding.  Regulatory  approval was not
required  for the  payment  of 1999  dividends.  Approximately  $80  million  of
HSBIIC's  statutory  surplus is available for distribution to HSB Group, Inc. in
2000 without prior regulatory approval.

The table above  presents  consolidated  results of HSB Group,  Inc. (HSB or the
Company).


Overview of Results of Operations

Income from continuing  operations for 1999,  excluding the 1998 gain on sale of
Industrial  Risk Insurers (IRI) discussed  below,  decreased $7.5 million or 9.3
percent  from 1998.  The decline in  after-tax  earnings  was  primarily  due to
reduced  underwriting  profits as well as a decline in the engineering  services
operating gain. The impact of these items was partially  offset by higher income
from investment  operations,  virtually all of which resulted from increased net
realized  gains  in  1999.  Excluding  the  gain on sale  of  IRI,  income  from
continuing  operations per common share on a diluted basis decreased 6.4 percent
in 1999 as compared to 1998.

                                       26
<PAGE>

In  comparison  to 1998,  the major  contributors  to the  reduction  in pre-tax
earnings (exclusive of realized gains) were: increased information systems costs
(including Year 2000 remediation costs) of $8 million;  reduced profits from HSB
Industrial Risk Insurers of $7 million;  change in management and other expenses
related to consolidation and relocation of certain businesses of $5 million; and
$3 million of reduced margins in certain engineering businesses.

Net income for 1998 included  after-tax  gains on the sale of HSB's  interest in
IRI of $23.8 million and Radian International LLC (Radian LLC) of $30.3 million.
The Radian LLC gain is net of  after-tax  operating  losses of $6.6 million that
were deferred in 1997 when the decision was made to exercise HSB's option to put
the Company's  interest to The Dow Chemical  Company (Dow).  As a result,  HSB's
interest in Radian LLC was classified as a  discontinued  operation in 1997. The
Company's after-tax earnings,  excluding the after-tax gains on sales of IRI and
Radian LLC,  increased  21.1 percent in 1998 compared with 1997 due to increased
underwriting  profits,  improved  engineering  results  and higher net  realized
gains. Income from continuing operations, excluding the gain on sale of IRI, per
common share on a diluted basis increased 21.4 percent in 1998 from 1997.

Total  revenues grew 4.7 percent in 1999 as compared to a decline of 4.0 percent
in 1998. The increase in 1999 was attributable to growth in engineering services
as well as strong realized  investment gains offset by a reduction in net earned
premiums.  Gross  earned  premiums  grew 6.9 percent in 1999 and 26.5 percent in
1998. In 1999, much of this increase was attributable to the continued growth in
our commercial book of business as well as a full year's earnings related to the
1998 acquisition of the Kemper book noted in the Other  Developments  section of
this Management's Discussion and Analysis (MD&A).

Ceded premiums increased 18.0 and 217.0 percent in 1999 and 1998,  respectively,
resulting  from  the  HSB  Industrial  Risk  Insurers  arrangement  and  related
reinsurance  with  Employers  Reinsurance  Corporation  (ERC),  as  well  as the
increasing  effect  of  the  Company's   reinsurance   programs  which  utilized
significantly  more quota share reinsurance on certain of our books of business.
The  Company   anticipates  that  quota  share  reinsurance  will  not  have  as
significant a role as 2000 progresses.

The combined  ratio for the Company  increased to 94.4 percent in 1999 from 89.6
percent in 1998. In 1997,  the combined  ratio was 91.7 percent.  The 1999 ratio
was adversely impacted by the increase in the expense ratio from 45.4 percent in
1998 to 51.0 percent in 1999.

Engineering  services revenue increased 27.9 percent in 1999 and 52.5 percent in
1998.  The growth in both 1999 and 1998 was led by additional  revenues from our
recent acquisitions. Operating margins decreased to 2.5 percent from 7.8 percent
in 1998. The investment of operating funds to develop new products and establish
start-up  operations,  and the consolidation of certain  businesses coupled with
reduced volume and profits in certain of our traditional  engineering businesses
caused margins to contract from 1998.

Income from investment  operations increased 16.9 percent in 1999 primarily as a
result of increased realized  investment gains from repositioning the investment
portfolio due to market  fluctuations  and to keep the absolute amount of common
equities from exceeding a certain targeted percentage of the Company's Generally
Accepted Accounting  Principles (GAAP) capital.  Net investment income grew 74.5
percent in 1998 from the investment of proceeds from the sales of IRI and Radian
LLC and the issuance of capital securities in the second half of 1997.

The effective tax rate on income from continuing operations before distributions
on capital  securities  for 1999 was 28.2  percent  compared to 29.6 percent and
26.8 percent for 1998 and 1997, respectively. Tax rate fluctuations occur as the
levels of  underwriting  and  engineering  services  results and realized  gains
change  the  mix of  pre-tax  income  between  fully  taxable  earnings  and tax
preferred  earnings.  Various tax credits  (primarily  foreign tax credits) also
impact  the  effective  rate.  The  Company  continues  to manage its use of tax
advantageous investments in an attempt to maximize after-tax earnings.

HSB Industrial Risk Insurers

The reinsurance  agreements effective January 1, 1998 between The Hartford Steam
Boiler  Inspection  and Insurance  Company  (HSBIIC),  ERC and IRI, as discussed
below,  were  terminated  with  respect to loss or  liabilities  arising  out of
occurrences  taking place on or after January 1, 2000. As a result,  HSBIIC will
no longer retain 85 percent of the equipment  breakdown insurance and 15 percent
of the property insurance of the combined insurance  portfolio for risks arising
on or after January 1, 2000. The joint  underwriting  association that was known
as HSB  Industrial  Risk  Insurers  will,  from  January  1,  2000,  be known as
Industrial Risk Insurers (IRI).

Concurrent with the termination of the reinsurance  agreements,  HSBIIC, ERC and
IRI replaced the operating  agreement  dated January 1, 1998. The new agreement,
effective  January 1, 2000,  calls for HSBIIC to retain 0.5  percent  membership
share in IRI with the ability to increase  its total share up to a maximum of 10
percent,  at no cost,  at HSBIIC's  option.  In  addition,  the  agreement  also
establishes an arrangement for HSB to perform  equipment  breakdown  engineering
and inspection services for clients of IRI and provides for a fixed fronting fee
in the event  that IRI  continues  to use  HSBIIC's  licenses.  HSBIIC  received
payments of $27 million in December  1999 related to the partial  settlement  of
unearned  reinsurance  premiums and ceding  commissions  due to HSBIIC under the
prior  agreement.  Final  settlement  is expected to occur in the second half of
2000.

On January 6, 1998,  HSBIIC sold its interest in IRI to ERC in accordance with a
previously   announced  purchase  and  sale  agreement  between  ERC  and  IRI's
twenty-three  member insurers.  HSBIIC received gross proceeds of $49.1 million,
prior to transaction  costs,  for its 23.5 percent share in IRI. The gain on the
sale of IRI was $36.6 million pre-tax and $23.8 million  after-tax.  Because the
sale was structured in part as a reinsurance transaction,  a portion of HSBIIC's
gross proceeds was utilized to reinsure in-force policies with ERC.

IRI  is  an  unincorporated,  voluntary  joint  underwriting  association  which
provides property  insurance for the class of business known as Highly Protected
Risks (HPR) for larger  manufacturing,  processing  and  industrial  businesses,
which have invested in protection against loss through the use of sprinklers and
other means.  IRI primarily  writes policies on a syndicate basis that specifies
to the  insured  the  percentage  share of risk  accepted  by each member of the
association.  Each member  company,  therefore,  operates as a direct insurer or
reinsurer on such policies and participates in the premiums and losses generated
thereunder in proportion to its membership interest.  In 1997 and 1996, HSBIIC's
membership shares were 23.5 and 14 percent  respectively;  in 1995 and prior the
shares were 0.5 percent.

In essence,  IRI facilitates the  proportional  sharing of risk under one policy
where  each  member  is  essentially  considered  to be the  direct  writer  for
reporting, premium tax and other regulatory purposes. Liability on such policies
is several and not joint, and therefore,  members are not responsible for policy
liabilities of the other  members.  An increased  participation  does not expose
HSBIIC to the effect of adverse loss development on claims incurred prior to the
effective date of the increase;  conversely a decrease in participation does not
release HSBIIC from the effect of adverse development.

Contemporaneous  with the close of the 1998 sale, IRI was reconstituted with ERC
(with a 99.5 percent  share) and HSBIIC  (with a 0.5 percent  share) as the sole
members.  The new association was renamed HSB Industrial Risk Insurers.  In 1999
and 1998,  HSBIIC wrote the business for HSB Industrial  Risk Insurers using its
insurance  licenses and provided  certain other services.  In addition,  through
various quota share  reinsurance  agreements  with ERC and HSB  Industrial  Risk
Insurers,   HSBIIC  transferred  its  manufacturing  book  of  business  to  HSB
Industrial  Risk  Insurers  in 1998 and  retained  85 percent  of the  equipment
breakdown  insurance  and 15 percent of the  property  insurance of the combined
insurance  portfolio.  This agreement was the largest contributing factor in the
growth of both gross earned premium and ceded premium. As a result, in both 1999
and 1998 transactions arising from this agreement comprise a significant

                                       28
<PAGE>

portion  of  the  reinsurance  asset,  unearned  insurance  premiums  and  ceded
reinsurance  payables  reflected  in the  Consolidated  Statements  of Financial
Position.

In  contemplation  of HSB's  expanded role in HSB Industrial  Risk Insurers,  on
December 31, 1997 a business trust formed by HSB sold $300 million of 20 year, 7
percent  Convertible  Capital Securities in a private placement to ERC (see note
13). The  Convertible  Capital  Securities  are  convertible  into shares of HSB
common stock, at any time, subject to regulatory approval, at a conversion price
of $56.67 per share. $250 million of the proceeds were contributed to HSBIIC and
$50 million were retained by HSB.


Discontinued Operations

On January 2, 1998,  HSBIIC  exercised its option to put its 40 percent share in
Radian LLC to Dow, for approximately $129 million,  net of expenses.  Radian LLC
was formed in January 1996 as a joint venture with Dow to provide environmental,
engineering,   information   technology,   remediation  and  strategic  chemical
management services to industries and governments worldwide.  In connection with
the formation of the new company,  HSBIIC  contributed  substantially all of the
assets and  liabilities of its wholly owned  subsidiary,  Radian  Corporation to
Radian LLC. The results of Radian LLC were classified as discontinued operations
following  ratification in July 1997 by HSB's Board of Directors of management's
decision to exercise its put. The after-tax gain of $30.3 million  recognized in
1998 is net of deferred losses  previously noted.  Prior to July 1997,  HSBIIC's
share of the joint venture's results was recorded as equity in Radian.


Recent Accounting Developments

The  Accounting  Standards  Executive  Committee  of the  American  Institute of
Certified Public Accountants  (AcSEC) issued three Statements of Position (SOPs)
that became  effective for fiscal years  beginning  after December 15, 1998: SOP
97-3,  "Accounting  by Insurance  and Other  Enterprises  for  Insurance-Related
Assessments," SOP 98-1, "Accounting for the Costs of Computer Software Developed
or Obtained for Internal Use" and SOP 98-5,  "Reporting on the Costs of Start-Up
Activities."   Because  the  Company's   accounting  policies  were  already  in
compliance with these SOPs, the implementation of these statements had no impact
upon the results of operations, financial condition or cash flows.

In June 1998, the Financial  Accounting  Standards Board (FASB) issued Statement
of Financial  Accounting  Standards  (SFAS) No. 133,  "Accounting for Derivative
Instruments and Hedging Activities"  subsequently  amended by SFAS No. 137. This
statement   establishes   accounting  and  reporting  standards  for  derivative
instruments,   including  certain  derivative   instruments  embedded  in  other
contracts  and for hedging  activities.  It  requires  that all  derivatives  be
recognized  as either  assets  or  liabilities  in the  statement  of  financial
position and that such  instruments be measured at fair value. In addition,  all
hedging relationships must be designated,  reassessed and documented pursuant to
the  provisions of SFAS No. 133. This statement is effective for the Company for
the first quarter of 2001. Based on the Company's  current  investment  policies
and practices,  the Company  anticipates  that the adoption of the provisions of
SFAS No.  133 will not have a  significant  effect  on  results  of  operations,
financial condition or cash flows.

In October 1998,  AcSEC issued SOP 98-7,  "Deposit  Accounting:  Accounting  for
Insurance and Reinsurance  Contracts That Do Not Transfer  Insurance  Risk." The
SOP identifies  several methods of deposit  accounting and provides  guidance on
the  application  of each  method.  This  SOP  became  effective  for  financial
statements for fiscal years beginning after June 15, 1999. Currently the Company
is not  party  to any  contracts  that do not  comply  with  the  risk  transfer
provisions  of SFAS No.  113,  "Accounting  and  Reporting  for  Reinsurance  of
Short-Duration and Long-Duration Contracts," and, therefore, does not anticipate
the adoption of SOP 98-7 will have a material  impact on results of  operations,
financial condition or cash flows.

Other Developments

In July 1999, HSBIIC acquired Structural Integrity Associates, Inc. (Structural)
based in San Jose,  California.  Structural  is an  engineering  consulting  and
inspection services firm specializing in the analysis, control and prevention of
structural  and  equipment  failures.  It offers a full array of services,  from
inspection and condition assessment,  to monitoring and remaining life analysis,
repair,  remediation  and  total  risk  management  of  critical  equipment  and
structures.

HSBIIC completed an acquisition of the monoline boiler and machinery business of
Kemper  Insurance  Companies  (Kemper) and  Kemper's  ASME  inspection  services
business that certifies boiler and pressure vessel compliance with the codes and
standards of the American  Society of Mechanical  Engineers,  effective  July 1,
1998.  The two  companies  also  completed an  agreement  for HSBIIC to reinsure
boiler and machinery  coverage  written as part of Kemper's  commercial  package
policies.

On April 21, 1998, the Board of Directors  approved a three-for-two  stock split
for shares of record on May 1, 1998. The additional  shares were  distributed on
May 22,  1998.  In  accordance  with SFAS No.  128,  "Earnings  per  Share," all
earnings per share presentations have been adjusted to reflect the impact of the
stock split, including retroactive restatement of prior periods.

In April 1998,  HSB acquired  Solomon  Associates,  Inc.  (SAI) based in Dallas,
Texas.  SAI  is  an  engineering   management   consulting  firm  that  provides
comparative performance  benchmarking consulting to the refining,  petrochemical
and power  generation  industries.  SAI establishes  efficiency and productivity
benchmarks for 80 percent of the worldwide  petroleum  refining  industry.  This
acquisition  expands  HSB's  engineering   management  consulting  services  and
benchmarking capability.

Insurance operations include the underwriting results of HSBIIC, HSB Engineering
Insurance  Limited (EIL), The Boiler  Inspection and Insurance Company of Canada
(BI&I), The Allen Insurance Company,  Ltd., The Hartford Steam Boiler Inspection
and Insurance  Company of Connecticut,  The Hartford Steam Boiler Inspection and
Insurance  Company of Texas and HSBIIC's  participation  in HSB Industrial  Risk
Insurers and various other pools.

Gross earned  premiums in 1999  increased  6.9 percent  over 1998.  Much of this
growth  was  attributable  to the  integration  of certain  commercial  books of
business acquired in mid-1998;  growth in our client company business and a full
year of writing HSB Industrial  Risk Insurers  policies  utilizing the Company's
licenses.  In 1998, a portion of HSB Industrial Risk Insurers  policies in-force
were written/renewed  utilizing the licenses of other insurers. The increases in
gross  premiums  were offset by premium  declines in certain  operations  within
Global  Special Risks.  In some areas of the Company's  direct  businesses,  the
market  continued to experience  price erosion in 1999 as the number of insurers
offering  capacity  expanded.  HSB

                                       30
<PAGE>

will not write business at rates that do not provide  sufficient  opportunity to
earn a profit. As a result, the Company  anticipates that premiums in the Global
Special Risks areas may continue to experience  revenue  declines.  In addition,
the new January 1, 2000  agreement  with IRI,  previously  discussed,  will also
result in a decrease in gross earned  premiums.  In 1998,  gross earned premiums
increased  26.5 percent  primarily as a result of HSB  Industrial  Risk Insurers
($155.4  million)  as  well  as the  addition  of the  Kemper  portfolio  to our
commercial business.

Domestically,  exclusive of HSB Industrial Risk Insurers,  gross earned premiums
increased  $34.8  million or 9.3 percent in 1999 due to the  integration  of the
Kemper  portfolio  and  growth in our  client  company  business.  Gross  earned
premiums  representing  coverage  outside the U.S.,  exclusive of HSB Industrial
Risk Insurers,  decreased 12.5 percent to $116.8 from $133.5 million in 1998 due
to price erosion and maintenance of strict underwriting standards.

In 1998, domestic gross earned premiums,  excluding the impact of HSB Industrial
Risk Insurers, remained flat as a result of the combination of growth in written
premiums from our client  companies offset by reductions in our domestic special
risk premiums.  Gross earned premiums  representing  coverage  outside the U.S.,
exclusive  of HSB  Industrial  Risk  Insurers,  increased  5.4 percent to $133.5
million.

The  insurance   industry,   in  general,   continues  to  undergo   significant
restructuring and consolidation.  Considerable  merger and acquisition  activity
has  occurred  over the last  several  years and,  with the advent of  financial
services reform,  more  contraction is possible in the future.  Depending on the
specific  companies  involved in these activities and other market factors,  the
level of reinsured business the Company assumes in the future could be impacted.
HSB is  positioned  to benefit from these  changes over the long term due to its
strong market  position and reinsurance  relationships  with  approximately  200
multi-line carriers;  while over the shorter term, there is both opportunity and
challenge.

The  increase  in ceded  premiums  of 18.0 and 217.0  percent  in 1999 and 1998,
respectively,  was primarily due to the HSB Industrial Risk Insurers arrangement
and  related  reinsurance  with  ERC,  as well as the  increasing  effect of the
Company's  reinsurance  programs  which over the past three years have  utilized
significantly  more quota share reinsurance on certain of our books of business.
Due to  changing  reinsurance  market  conditions  and the impact of the new IRI
agreement effective January 1, 2000, the Company is in the process of evaluating
and redesigning its current  reinsurance  programs that will place less reliance
on quota share reinsurance.  The Company anticipates this will lead to a reduced
level of ceded premiums.

Due to the new agreement with IRI,  coupled with a decline in our Global Special
Risks segment,  gross earned premiums are expected to decline in 2000.  However,
anticipated  changes in the  utilization of reinsurance may cause ceded premiums
to decline at a higher rate than gross earned premiums for 2000.

The Company participates in various facultative,  quota share and excess of loss
reinsurance  agreements  to limit its  exposure,  particularly  to  catastrophic
losses and high-risk lines and to provide additional capacity to write business.
The Company  evaluates its exposures and reinsurance needs annually to implement
a program that  corresponds  with the level of exposure it is willing to retain.
Because  the  Company  has primary  responsibility  to its  insureds,  a careful
evaluation of the financial strength of those reinsurers it cedes business to is
performed.  HSB's  reinsurance  costs  continue to be impacted by its prior loss
experience and business growth, as well as the design of its program.

* Includes approximately $2.0, $5.0 and $3.3 million of subrogation  recoveries,
respectively.

Claims and adjustment  expense reserves comprise one of the largest  liabilities
on the Company's  Consolidated  Statements of Financial  Position.  Reserves are
established  to  record  the  Company's  estimates  of  total  losses  and  loss
adjustment  expenses  that will  ultimately  be paid under  direct  and  assumed
insurance  contracts.  Loss reserves  include claims and adjustment  expenses on
claims  that have been  reported  but not yet  settled  and those that have been
incurred but not yet reported to the Company.  The length of time that  reserves
are carried on the Consolidated  Statements of Financial  Position is a function
of the pay-out  patterns  associated  with the types of coverage  involved.  The
majority of claims the Company incurs are  short-tailed  in nature,  relative to
the property-casualty industry as a whole, meaning they generally settle shortly
after claims are reported.  The Company's  loss reserve  estimates  reflect such
variables as past loss experience and inflation.  In addition, due to the nature
of much of the Company's types of coverage,  complex  engineering  judgments are
involved.  Previously  established loss reserves are regularly  adjusted as loss
experience  develops  and new  information  becomes  available.  Adjustments  to
previously established reserves are reflected in the financial statements in the
period in which the  estimates  are  changed.  The Company does not discount its
loss reserves.

The  loss  ratio  improved  0.8  percentage  points  in  1999  from  1998.  This
improvement was primarily attributable to increased use of reinsurance. The 1999
results were impacted by $10 million of domestic  weather-related events and the
Taiwan  earthquake as well as $10 million in losses related to medical equipment
insurance contracts.  These insurance contracts  represented less than 1 percent
of the Company's  revenues.  The loss ratio  decreased 0.2 percentage  points in
1998 as  compared  to 1997.  Loss  results in 1998 were  impacted  by severe ice
storms in Canada, as well as a few significant losses in our other international
businesses.  Prior year loss  development in 1999,  1998 and 1997 added 0.1, 2.8
and 1.7 percentage points to the respective loss ratio. The components of claims
and adjustment expenses, net of reinsurance, are displayed above.

Gross claims and adjustment  expenses were $684.7 million in 1999 as compared to
$619.6 million in 1998 and $263.1 million in 1997.  This increase was the result
of weather-related  events domestically,  the Taiwan earthquake and large losses
in our Global Special Risks business,  all of which were largely reinsured.  The
significant  increases in claim reserves and  reinsurance  assets since December
31, 1998 largely  relate to these events.  In 1998, the increase in gross claims
was largely due to the Company's  role as direct writer of HSB  Industrial  Risk
Insurers'  policies and  included  approximately  $154  million  from  Hurricane
Georges on exposures written by HSB Industrial Risk Insurers. On a net basis the
impact on HSB from such hurricane  losses after cessions to HSB Industrial  Risk
Insurers and reinsurance recoveries was $1.9 million.

Although   reported   claim   activity  has  been   negligible   at  this  time,
quantification of the Company's exposure to Year 2000 losses and loss adjustment
expenses are not  reasonably  estimable  as  applicable  policy and  reinsurance
contract wordings have not been legally tested in the context of such losses.

                                       32
<PAGE>

The expense  ratio  increased  to 51.0 percent in 1999 from 45.4 percent in 1998
and 47.3  percent in 1997. A portion of the 1999  increase in the expense  ratio
was  attributable  to  increases  in  policy  acquisition  costs.  Increases  in
commission  rates that reflect changes in the mix of business,  primarily in the
commercial  segment,  increased the expense ratio  approximately  1.9 percentage
points.  In 1999, the Company's  results were  negatively  impacted by increased
information  systems costs of $8 million (including Year 2000 remediation costs)
and $5  million  of  charges  related  to a  change  in  management  at HSB  and
consolidation and relocation of certain businesses. Approximately $11 million of
these amounts were allocated to the insurance operations, thereby increasing the
expense ratio by 2.9 percentage points.

The 1998  expense  ratio  improvement  of 1.9  percentage  points  over 1997 was
primarily  related to the new quota  share  reinsurance  agreements  and the HSB
Industrial Risk Insurers  arrangement with ERC, both of which resulted in ceding
commissions  to  HSBIIC  that  positively  impacted  our  expense  ratio  by 3.9
percentage points. A portion of such ceding commission was intended to reimburse
HSBIIC for the additional  costs of managing HSB Industrial Risk Insurers and to
offset the reduction in net earned premiums.

The  following  information  summarizes  key  financial  results  by  reportable

The  Commercial  business has shown strong revenue growth year over year despite
significant  price  competition  as HSB continues to focus on its client company
strategy.  Net earned  premiums in the  Commercial  segment rose $28.9 and $37.3
million in 1999 and 1998, respectively,  due primarily to the integration of the
Kemper portfolio and growth in our client company  business,  offset by declines
in direct writings.  In 1999, domestic operations posted an underwriting gain at
a lower  margin  than 1998 due to the  increased  expense  ratio.  International
operations  posted  an  improved  underwriting  gain as 1998 was  more  severely
impacted by  weather-related  claims.  In 1998,  domestic  operations  posted an
underwriting  gain  that  was  partially  offset  by  a  difficult  claims  year
internationally,  particularly  due to severe ice storms that  affected  over 30
percent of Canada. The high tax benefit recognized on Canadian losses caused the
effective tax rate to decline from 1997.

Global Special Risks net earned  premiums  declined $38.0 million in 1999.  This
decrease  relates  primarily  to  increased  ceded  premiums  related to the HSB
Industrial Risk Insurers business. In addition, price erosion and maintenance of
strict  underwriting  standards,  coupled with changes in reinsurance  programs,
contributed  to the  decline in 1999.  In 1998,  net earned  premiums  decreased
$133.5  million  primarily  due to the  increased  use of  reinsurance  and  the
arrangement  with HSB Industrial Risk Insurers.  Global Special Risks net income
decreased in 1999  primarily as a result of the  declining  book.  In 1998,  the
international  businesses were impacted by adverse claims experience as compared
to 1997.  In 1998,  income  taxes as a percentage  of net income  increased as a
result of a decreased use of foreign tax credits.

As part of the arrangement  with HSB Industrial Risk Insurers,  HSBIIC wrote all
direct policies for HSB Industrial Risk Insurers and then ceded back these risks
100 percent to HSB Industrial  Risk Insurers.  HSBIIC then reinsured  ERC's 99.5
percent share of the business  resulting in the  assumption of 85 percent of the
equipment  breakdown  business  and 15 percent of the  property  business.  As a
result of the termination of the ERC  reinsurance  agreement and the replacement
of the IRI agreement  effective  January 1, 2000, as

                                       33

previously  discussed,  the Company anticipates that Global Special Risks' gross
earned and ceded premiums, as well as the fees/expense  reimbursement  generated
from managing the IRI business will continue to decline.

- ------------------------------------------------------------------------

Engineering  services  operations  include  the results of  HSBIIC's,  EIL's and
BI&I's  engineering   services,   HSB  Reliability   Technologies  (HSBRT),  HSB
Professional Loss Control, HSB International,  SAI, Structural and the Company's
interest in Integrated Process Technologies, LLC (IPT).

Engineering  services revenues increased 27.9 percent in comparison to 1998. The
growth in revenues is primarily due to significant  increases  related to IPT, a
full year's integration of the SAI acquisition which occurred in April 1998, the
Structural  acquisition  in July 1999 and EIL's  engineering  services  revenues
generated through other acquisitions. In 1998, revenue increases of 52.5 percent
were generated by HSBRT; EIL's acquisition of Haughton's engineering in the last
quarter of 1997; and the addition of SAI in April 1998.

Operating margins decreased to 2.5 percent from 7.8 percent in 1998. The decline
in operating  margin from the previous year reflects the investment of operating
funds to develop new products and  establish  start-up  operations  coupled with
reduced volume and profits in certain of our traditional engineering businesses,
particularly  HSBRT. In addition,  the Company recorded a charge of $0.7 million
related  to costs  associated  with the  consolidation  of  certain  engineering
activities.  Margins  increased  0.8  percentage  points  in 1998 as a result of
improved  field  service staff  utilization  and cost  efficiencies,  which were
offset somewhat by the start-up costs of integrating certain acquisitions.

In  July  1999,  HSBIIC  acquired  Structural  based  in San  Jose,  California.
Structural is an  engineering  consulting  firm that  specializes in prevention,
control and repair of structural and mechanical failures.  The Company continues
to focus on  identifying  and  evaluating  acquisition  candidates  in the niche
engineering  management  consulting  service  business,   primarily  in  process
industries,   in  order  to  expand  or  complement  its   engineering   service
capabilities.

The Company's  investment strategy is to maximize total return on the investment
portfolio  through  investment  income  and  capital  appreciation.   Investment
strategies  for any given year are  developed  based on many  factors  including
operational results, tax implications,  regulatory requirements, interest rates,
dividends to  stockholders,  servicing  requirements  of capital  securities and
market  conditions.  The

                                       34
<PAGE>

investment  portfolio  includes a wide variety of high quality equity securities
and both domestic and foreign fixed maturities.  The Company continues to manage
its use of tax  advantageous  investments  in an attempt to  maximize  after-tax
investment earnings.  The Company does not engage in cash flow underwriting;  it
seeks to have underwriting profit each year.

None of the Company's  claim reserves are  discounted as most claims settle,  on
average,  within  one  year.  Therefore,  the  Company  does  not  use  duration
measurements  in managing its interest rate exposure.  Instead,  HSB manages its
portfolio on a segmented basis.  Approximately  $300 million (cost basis) of the
Company's  invested  assets  (comprised  of perpetual and  redeemable  preferred
stocks and  corporate  bonds) are  utilized  to provide  interest  coverage  and
potential   principal  repayment  over  the  life  of  the  convertible  capital
securities issued on December 31, 1997. The remainder of the Company's  invested
assets, exclusive of cash and cash equivalents, short-term securities and common
stocks are invested to provide income for the future.  There are three portfolio
areas with quite  different  maturity/call  characteristics.  The  portfolio  of
traditional bonds of approximately $245 million has an average life of 22 years,
with over 50  percent of that  portfolio  callable  in less than ten years.  The
sinking fund preferred portfolio of $43 million, based on expected calls, has an
estimated life of three years.  The $52 million  adjustable rate preferred stock
portfolio, based on expected calls, has an estimated life of five years.

The Company  believes the  expected  cash flows from the  Company's  operations,
maturities  and calls are  adequate  to enable  the  Company  to  respond to the
previously discussed parameters that impact its investment strategy.

Net  investment  income for 1999  remained  flat  compared to 1998 and increased
$27.4 million in 1998 as compared to 1997 due to the investment of proceeds from
capital securities issued during the second half of 1997. In addition,  proceeds
from  the  January  1998  sale  of  HSB's   interests  in  IRI  and  Radian  LLC
significantly  increased  investable  funds.  Declining  yields available on new
fixed maturities relative to higher yields on maturing investments over the past
few years have also moderated  investment  income growth.  Net investment income
has also been impacted by calls of high yielding preferred stocks.

Realized  investment  gains  increased  $15.2  million  in 1999 as a  result  of
repositioning  the investment  portfolio due to market  fluctuations and to keep
the  absolute  amount of  common  equities  from  exceeding  a certain  targeted
percentage of the Company's  GAAP capital.  In 1998,  realized  gains  increased
$11.3 million as a result of call premiums on fixed income investments and sales
of certain  convertible  securities  and  common  stocks in  response  to market
conditions.

In 1997,  realized gains were reduced by $30.7 million (all of which were offset
by and  represented  portfolio  appreciation  and returns that were realized) to
reflect the estimated fair value of three "zero cost collar  contracts"  entered
into at the end of 1996 to mitigate the effects of market risk on the  Company's
U.S. common stock portfolio (which,  for management  purposes,  included certain
convertible  preferreds).  Each contract had a notional value of $50 million and
maturity  dates ranging from November 1997 to January 1998.  The contracts  were
European  style,  which means they only settled upon  maturity.  The  contracts,
which were entered into when the Standard & Poor's 500 Index (S&P 500 Index) was
744.3,  allowed HSBIIC to recover from the  counterparty  if the index was below
695.2 at the time of maturity, and required HSBIIC to reimburse the counterparty
if the index was above a range of 811.3 to 818.7 at the time of maturity.

Through its U.K. subsidiary, EIL, the Company writes business in Malaysia and is
required  to  maintain  ringgit  denominated  investments  based on the level of
premiums written in Malaysia. At December 31, 1999, 1998 and 1997, the Company's
deposits  were 20, 29 and 50 million  ringgits,  respectively.  This  equated to
$5.1, $7.1 and $12.8 million at December 31, 1999, 1998 and 1997,  respectively.
In 1997, due to currency  fluctuation  in Southeast  Asia,  realized  investment
gains were negatively impacted by $7.4 million.

HSB's  investment  portfolio  continues  to consist of  high-grade  domestic and
foreign  investments.  Excluding short-term  investments,  HSB's investments are
primarily comprised of publicly traded, highly liquid

                                       35
<PAGE>

securities.  At the end of 1999, HSB's fixed maturities portfolio comprised 52.9
percent of the value of the invested  assets.  The credit  quality of HSB's bond
investments at December 31, 1999, averaged an A rating. HSB's portfolio does not
include any bonds in default as to either  principal or interest.  Bonds held at
December  31,  1999 had a fair  value of $299.8  million.  Redeemable  preferred
stocks averaged a BBB rating.  During 1999 bond yields continued to move up, the
impact of which has caused a reduction in the  Company's  unrealized  gains with
respect to fixed income securities by approximately $64.5 million pre-tax.

The carrying value of the equity securities  portfolio  represented 41.3 percent
of the  investments at December 31, 1999. This included $65.3 million of pre-tax
unrealized  investment  gains of which $92.6 million related to common equities,
offset by $27.3 million of preferred unrealized investment losses. The Company's
common  equities,  which are  comprised of primarily  Standard & Poor's 500 (S&P
500) "large cap"  stocks,  essentially  modeled the  performance  of the S&P 500
Index in 1999. HSB also recorded $22.1 million of dividends and $43.5 million of
net pre-tax  realized gains from this  portfolio in 1999. The Company's  largest
single holding accounted for less than 1 percent of total  consolidated  assets.
Realized  investment  gains  increased  in 1999 over 1998 (and in 1998 over 1997
taking into account the $30.7 million loss on the "zero cost collar  contracts")
as HSB managed its portfolio to respond to changing  market  conditions  and tax
planning opportunities.


Market Risk

Market risk generally  encompasses systemic risks or risks associated with macro
factors  relating to economic losses due to adverse changes in the fair value of
a financial instrument.  Market risk relates to the variability of market prices
and/or cash flows associated with changes in interest rates,  securities prices,
market indices,  yield curves or currency  exchange rates and is inherent to all
financial  instruments.  The Company's  investment strategy is to maximize total
return  on the  investment  portfolio  through  investment  income  and  capital
appreciation  and  is  based  on  such  factors  as  operational   results,  tax
implications,    regulatory   requirements,   interest   rates,   dividends   to
stockholders,   servicing   requirements   of  capital   securities  and  market
conditions.

The focus of this  disclosure is on one element of market risk - price risk. For
the  Company,  price risk relates to changes in the level of prices of financial
instruments due to changes in interest rates,  equity prices or foreign exchange
rates.  The primary price risk  exposures of the Company relate to interest rate
and equity price risk.

For  purposes  of  this  disclosure   market  risk  sensitive   instruments  are
categorized as  instruments  entered into for trading  purposes and  instruments
entered  into for  purposes  other than  trading.  The Company does not hold any
financial  instruments entered into for trading purposes and, therefore,  market
risk  sensitive  instruments  are  classified  as held for  purposes  other than
trading.


Interest Rate Risk

Interest  rate risk is the major price risk facing the  Company's  fixed  income
portfolio.  Such  exposure  can subject  the  Company to economic  losses due to
changes  in the level or  volatility  of  interest  rates.  Bond  prices  change
inversely  with the direction of interest  rates.  Generally,  as interest rates
rise,  prices for fixed  income  instruments  will fall.  As rates  decline  the
inverse is true. The Company attempts to mitigate this risk by investing in high
quality issues using a buy and hold approach.


Equity Market Risk

Equity market risk is defined as the chance that market  influences  will affect
the expected  returns of all equities.  Returns are  influenced  not only by the
fundamental attributes of investment  securities,  but by the price movements of
the  general  marketplace.  Much  of  this  depends  on the  sensitivity  of the
individual issue

                                       36
<PAGE>

to the  overall  market.  The  Company  attempts  to reduce  this  risk  through
diversification and a focus on high quality, blue chip investments.


Foreign Exchange Risk

Foreign  exchange  risk  arises  from the  possibility  that  changes in foreign
currency   exchange  rates  will   adversely   impact  the  value  of  financial
instruments.  The Company has foreign  exchange  exposure  when it buys or sells
foreign currencies or financial  instruments  denominated in a foreign currency.
The  Company's  foreign  transactions  are  primarily  denominated  in  Canadian
dollars.


Sensitivity Analysis

The following  analysis  illustrates  the sensitivity of the market value of the
Company's financial  instruments to selected changes in market rates and prices.
The range of changes selected reflects the Company's view of reasonably possible
market movements over a one-year period. The range of values selected should not
be interpreted as the Company's  prediction of future market events,  but rather
an illustration of the impact of such events.

The  analysis  assumes  that the  composition  of the  Company's  interest  rate
sensitive assets and liabilities existing at the beginning of the period remains
constant  over the period  being  measured  and also  assumes  that a particular
change  in  interest  rates  is  reflected  uniformly  across  the  yield  curve
regardless of the time to maturity. Also, the interest rates on certain types of
assets and  liabilities  may fluctuate in advance of changes in market  interest
rates,  while  interest  rates on other  types may lag behind  changes in market
rates.  Accordingly,  the analysis may not be indicative  of, is not intended to
provide  and does not  provide a precise  forecast  of the  effect of changes of
market interest rates on the Company's income or stockholders' equity.  Further,
the  computations  do not contemplate any actions the Company would undertake in
response to changes in interest rates.

The  sensitivity  analysis  assumes an  instantaneous  shift in market  interest
rates,  with scenarios of interest  rates  increasing and decreasing 100 and 150
basis  points  from their  levels at  December  31, 1999 and 1998 with all other
variables held constant. The analysis assumes the yield to worst methodology.  A
100 and 150 basis point increase in the market  interest rates would result in a
pre-tax  decrease in the net  financial  instrument  position of $50.1 and $38.1
million  for 1999 and  1998 and  $67.4  and  $55.1  million  for 1999 and  1998,
respectively.  Similarly,  a 100 and 150 basis point decrease in market interest
rates  would  result  in a  pre-tax  increase  in the net  financial  instrument
position  of $50.1  and  $38.1  million  for 1999 and 1998 and  $67.4  and $55.1
million for 1999 and 1998, respectively.

Portfolio  sensitivity  to these  variables  tends to  change  over  time due to
changes in  portfolio  composition  and changes in market  environment.  For the
fixed maturity portfolio,  sensitivity, as measured by duration,  increased from
5.48 at  December  31,  1998 to 8.37 at  December  31,  1999.  This  increase in
duration  is due  primarily  to  changes  that  occurred  in the  interest  rate
environment  during the period. The Company uses a yield to worst methodology to
calculate  duration.  This  assumes  that an  issuer,  given  the  current  rate
environment,  will call higher  coupon debt if  appropriate.  As interest  rates
increased   during  the  year,   the  call   feature  on  many   issues   became
non-applicable.  This change in the  environment  caused  portfolio  duration to
increase and a corresponding increase in sensitivity to interest rates.

The Company's long-term debt and convertible capital securities have been issued
at fixed rates, and as such,  interest expense would not be impacted by interest
rate shifts.  The impact of 100 and 150 basis point  increases in interest rates
on the fixed rate debt would  result in a  decrease  in the market  value of the
debt by $0.3  million in 1999 and 1998 and $0.5  million  in 1999 and 1998.  The
effect  of 100 and 150  basis  point  increases  in  interest  rates on the $300
million convertible capital securities would result in an estimated market value
of $247.6 and $296.4  million in 1999 and 1998, and $237.0 and $289.4 million in
1999 and 1998, respectively,  and is calculated without giving any effect to the
relationship  of the conversion  price to the current market price of HSB Group,
Inc.  common stock.  The impact of 100 and 150 basis point

                                       37
<PAGE>

increases in interest rates on the variable rate capital securities would result
in an additional  charge to pre-tax  income of $1.1 million in 1999 and 1998 and
$1.6 million in 1999 and 1998, respectively, per year. A 100 and 150 basis point
decrease in interest rates would increase pre-tax income by $1.1 million in 1999
and 1998 and $1.6 million in 1999 and 1998, respectively, per year.

Equity  price risk was  measured  assuming  an  instantaneous  10 percent and 25
percent change in the S&P 500 Index from its level at December 31, 1999 and 1998
with all other variables held constant. The Company's equity holdings (comprised
of common stocks and  non-redeemable  preferreds) were assumed to be 100 percent
correlated  to this index.  A 10 percent and 25 percent  increase or decrease in
the S&P 500 Index would result in a $21.4 and $24.9 million increase or decrease
in 1999 and 1998 and $53.4 and $62.4  million  increase  or decrease in 1999 and
1998,  respectively,  in the net financial  instrument  position.  The Company's
equity instruments'  sensitivity to equity market risk, as measured by portfolio
beta,  decreased  from 1.02 at December  31, 1998 to 0.98 at December  31, 1999.
This  change is  generally  attributed  to  portfolio  repositioning  during the
period.

The sensitivity analysis also assumes an instantaneous 10 percent and 20 percent
change in the foreign currency  exchange rates versus the U.S. dollar from their
levels at December 31, 1999 and 1998 with all other  variables held constant.  A
10 percent  and 20 percent  strengthening  of the U.S.  dollar  would  result in
decreases of $6.1 and $6.4 million in 1999 and 1998 and $12.2 and $12.4  million
in 1999  and  1998,  respectively,  in the net  financial  instrument  position.
Weakening of the U.S.  dollar versus all other  currencies  would result in like
increases in the net financial instrument position.

The following  table  reflects the estimated  effects on the market value of the
Company's  financial  instruments  due to an increase  in interest  rates of 100
basis  points,  a 10  percent  decline  in the S&P 500 Index and a decline of 10
percent in foreign currency exchange rates.

Statement of Comprehensive Income

In  addition  to the impact of HSB's  results of  operations,  the  Consolidated
Statements of  Comprehensive  Income  display the effects of price  movements on
HSB's  invested  assets.  In 1999,  the impact of rising  interest  rates on the
carrying values of the Company's fixed income  investments  more than offset the
strong  performance  of its common  equities such that 1999  cumulative  holding
gains,  net of taxes,  decreased  $45.2  million as compared to the  increase of
$28.1 million in 1998 and $21.3 million in 1997.

Liquidity refers to the Company's  ability to generate  sufficient funds to meet
the cash requirements of its business operations and financing obligations.  HSB
is a holding  company  whose  principal  subsidiary  is  HSBIIC.  HSB  relies on
investment  income,  primarily in the form of dividends from HSBIIC, in order to
meet its  short and  long-term  liquidity  requirements  including  the  service
requirements for its capital  securities.  The Company receives a regular inflow
of  cash  from  maturing   investments,   engineering   services  and  insurance
operations.  The mix of the  investment  portfolio  is  managed  to  respond  to
expected claim pay-out  patterns and the service  requirements  of the Company's
capital  securities.  HSB also  maintains cash  equivalents  and a highly liquid
short-term portfolio to provide for immediate cash needs and to offset a portion
of interest rate risk  relating to $110 million of Global  Floating Rate Capital
Securities.  During 1999,  HSB received  $152.7 million in dividends from HSBIIC
and at  December  31, 1999 the  holding  company had $143.2  million of cash and
invested  assets as compared  to $92.8  million at December  31,  1998.  Current
estimates are that HSBIIC has the capacity to dividend to HSB  approximately $80
million in 2000 without regulatory approval.

                                       39

On July 15, 1997, a trust  sponsored and wholly owned by the Company issued $110
million  aggregate  liquidation  amount  of  capital  securities  in  a  private
placement and 3,403 shares of common securities to the Company,  the proceeds of
which were invested by the trust in $113.4 million aggregate principal amount of
the  Company's  debt  securities.  On  November 5, 1997,  an exchange  offer was
commenced,  pursuant to which the capital  securities  originally  issued in the
private  placement were exchanged for capital  securities  that were  registered
with the Securities and Exchange  Commission  (the Capital  Securities)  and the
debt securities were exchanged for debt securities that were registered with the
Securities and Exchange Commission (the Debt Securities).

The Debt Securities  represent all of the assets of the trust. The proceeds from
the  issuance  of the Debt  Securities  were  used by the  Company  for  general
corporate purposes. The Debt Securities and related income statement effects are
eliminated  in the  Company's  consolidated  financial  statements.  The  $113.4
million  principal amount of Debt Securities  accrue and pay cash  distributions
quarterly  in  arrears  at a  variable  rate equal to the 90 day LIBOR plus 0.91
percent of the stated  liquidation  amount of $1,000 per Debt  Security  and are
scheduled to mature on July 15, 2027.

The Capital Securities accrue and pay cash distributions quarterly in arrears at
a  variable  rate  equal to the 90 day LIBOR  plus 0.91  percent  of the  stated
liquidation  amount of $1,000 per Capital  Security.  The current  coupon is 7.1
percent.  HSB has the right to defer payment of  distributions on the securities
at any time or from  time to time  for a period  not  exceeding  20  consecutive
quarterly  periods with  respect to each  deferral  period.  During an extension
period,  interest  will  continue to accrue and the amount of  distributions  to
which holders of the Capital  Securities are entitled will  accumulate,  and the
Company will be prohibited from paying any cash dividends on its common stock.

The Capital  Securities  are generally  non-callable  for ten years,  but may be
called earlier by HSB upon the  occurrence of certain tax events  including loss
of  deductibility  of interest on the  securities.  The Capital  Securities  are
mandatorily  redeemable  upon the  maturity of the Debt  Securities  on July 15,
2027,  or  earlier to the extent of any  redemption  by the  Company of any Debt
Securities.  The  redemption  price in either such case will be $1,000 per share
plus accrued and unpaid distributions to the date fixed for redemption.

The terms of the Debt  Securities,  the guarantee of the Company with respect to
the Capital Securities, the Indenture and the Trust Agreement together provide a
full guarantee of amounts due on the Capital Securities.  The Capital Securities
are  currently  rated BBB- by Standard & Poor's and BBB+ by Duff & Phelps credit
rating agencies.

On December 31, 1997, HSB Group,  Inc. sold $300 million of 20 year  Convertible
Capital  Securities  in a private  placement  to ERC.  The  Convertible  Capital
Securities are callable by the Company at its option (i) at any time after seven
years;  (ii)  upon the  occurrence  of  certain  tax  events  including  loss of
deductibility  of the  interest on the  securities;  (iii) in the event that HSB
vetoes a prospective purchaser of the Convertible Capital Securities; or (iv) in
the event of a change in control of ERC. The Convertible  Capital Securities are
mandatorily  redeemable  on December 31, 2017 and are  redeemable  at par plus a
redemption premium, at the option of ERC, in the event of a change in control of
HSB within five years following issuance of the securities.

The  Convertible  Capital  Securities are  convertible,  in whole or in part, at
ERC's option at any time,  subject to  regulatory  approval,  into shares of HSB
common stock at a conversion  price of $56.67 per share,  subject to adjustment.
HSB has  provided  certain  registration  rights to ERC in  connection  with the
common  stock into which the  Convertible  Capital  Securities  are  convertible
pursuant to a Registration Rights Agreement dated December 31, 1997. If ERC were
to exercise its conversion  rights in total, it would hold at December 31, 1999,
on a fully  diluted  basis,  approximately  15.4 percent of HSB's common  stock.
Pursuant  to  certain  provisions  contained  in the  Purchase  Agreement  dated
December 31, 1997, ERC has agreed to certain "standstill" arrangements which for
a period of five years will  preclude  ERC from  purchasing  any common

                                       40
<PAGE>

stock of HSB,  other than by exercise of its conversion  rights,  and will limit
its  ability to take  certain  other  actions  with  respect to HSB during  that
period.

The  securities  were  issued  through  HSB  Capital  II (Trust  II), a Delaware
business trust created by HSB, at a 7 percent coupon, payable semi-annually. The
Convertible  Capital  Securities  rank pari passu with the Global  Floating Rate
Capital  Securities  issued in July  1997.  Holders of the  Convertible  Capital
Securities   will  be  entitled   to  receive   preferential   cumulative   cash
distributions  accumulating  from  the date of  original  issuance  and  payable
semi-annually in arrears.  HSB has the right to defer payment of interest at any
time or from time to time for a period not exceeding 10 consecutive  semi-annual
periods  with  respect to each  deferral  period.  During an  extension  period,
interest  will  continue  to accrue  and the  amount of  distributions  to which
holders of the Convertible Capital Securities are entitled will accumulate,  and
HSB will be prohibited  from paying any cash dividends on its common stock.  HSB
has irrevocably  and  unconditionally  guaranteed all of Trust II's  obligations
under the Convertible Capital Securities.

Cash provided from operations  decreased to $43.2 million in 1999 as compared to
$55.6 million in 1998. The decrease was primarily  attributable to a $22 million
decline in net cash flows from HSBIIC's  participation  in HSB  Industrial  Risk
Insurers,  offset by an increase in  insurance  operating  cash flows.  Net cash
flows from HSB Industrial Risk Insurers were favorably impacted by a $27 million
accelerated  collection of  receivables  pursuant to the  termination of certain
reinsurance  agreements  between HSBIIC,  ERC and IRI, as previously  discussed.
Operating cash flows from  insurance,  excluding HSB  Industrial  Risk Insurers,
were  positively  impacted by a decline in net claims paid of 10.3  percent,  as
well as, a decrease in payments to reinsurers  for ceded premiums of 9.1 percent
offset by a decrease in premiums collected of 5.5 percent.

Cash provided  from  operations  increased  $29.5 million in 1998 as compared to
1997. Insurance  operations cash flows,  excluding HSB Industrial Risk Insurers,
were  impacted  by a decline in net claims paid of 2.9  percent  while  premiums
collected  increased  6.5 percent.  Payments to  reinsurers  for ceded  premiums
increased 70.5 percent from 1997. HSBIIC's  participation in HSB Industrial Risk
Insurers positively impacted cash flow from operations $35.3 million.

Capital resources consist of shareholders'  equity,  capital securities and debt
outstanding and represent those funds deployed,  or available to be deployed, to
support business  operations.  Common  shareholders' equity of $376.5 million at
December 31, 1999 decreased  $42.8 million since December 31, 1998. The decrease
primarily  reflects net income of $72.8  million and net stock  issuance of $7.7
million,  offset by a decrease in unrealized  investment  gains,  net of tax, of
$69.8  million and  dividends  of $49.9  million.  The  decrease  in  unrealized
investment  gains of $69.8 million  results  principally  from realized gains of
$26.4 million and unrealized depreciation of fixed maturities and non-redeemable
preferreds  of  $63.2  million,  the sum of which is  offset  by net  unrealized
appreciation of common stocks and convertible preferreds of $18.0 million.

On January 24, 2000, the Board renewed the  authorization  to repurchase up to 3
million shares of common stock. HSB repurchased  approximately  0.1, 1.2 and 1.5
million shares at a cost of $4.4,  $47.7 and $54.0 million during 1999, 1998 and
1997, respectively.

At December 31, 1999,  HSBIIC had  significant  short-term  borrowing  capacity.
HSBIIC is currently  authorized to issue up to $75 million of commercial  paper.
Commercial  paper  outstanding at December 31, 1999 and 1998 was $38.6 and $20.0
million,  respectively.  The weighted-average  interest rate was 6.0 percent and
5.2 percent at December  31, 1999 and 1998,  respectively.  In 1999,  Standard &
Poor's and Duff & Phelps credit rating services reaffirmed their highest ratings
for the commercial paper.

The  Company  writes  business in European  markets  primarily  through its U.K.
subsidiary,  EIL. The adoption of a common  currency (the euro) by eleven of the
fifteen member countries of the European Union on January 1, 1999 did not result
in a substantial  change in the business or a significant  increase in costs. In
part,  this is due to the  fact  that  much of  EIL's  business  is U.S.  dollar
denominated.  Also, the U.K. is not a

                                       41
<PAGE>

first wave euro country.  The Company will continue to monitor  developments and
assess impacts on markets, pricing and reporting.


Year 2000

In 1996, the Company began a  comprehensive  effort to assess and address issues
affecting the Company,  which related to the inability of computer equipment and
embedded computer chips to distinguish  between the year 1900 and the year 2000.
Year 2000  problems  could  result  in  system  failures,  product  failures  or
miscalculations  causing  disruptions  of operations.  If the computer  systems,
software  products and devices do not correctly process dates after December 31,
1999, business could be adversely affected.

As a part of this effort, the Company established a Year 2000 Program to address
four key areas: (i) applications software, primarily consisting of the Company's
policy management,  claims,  financial  recording and reporting,  human resource
systems and engineering  databases and systems;  (ii)  infrastructures,  such as
mainframe and corporate servers,  workstations and networking components;  (iii)
embedded  technology in facilities in which the Company  conducts its operations
and in testing equipment used by the Company's  engineering  staff; and (iv) key
business  partners and  suppliers.  In addition,  the Company has  evaluated and
continues to evaluate its potential  insurance coverage exposures arising out of
the Year 2000 and its impact on insured equipment.

The Company has completed all stages of its Year 2000  Program:  (i)  assessment
and   analysis;   (ii)   development,    renovation   and   replacement;   (iii)
implementation;  (iv) testing and validation; (v) contingency planning; and (vi)
audit and review.

The Company continues to monitor information systems and transaction  processing
with the  objective of  identifying  and  correcting  any  undetected  errors of
omission or commission which may have occurred in the execution of its Year 2000
Program.

Subsequent  to January 1,  2000,  HSB has not  encountered  any  disruptions  or
anomalies  that  affected  any  critical  internal  system nor  experienced  any
material  disruption  in its  business  due to the  inability  of any of its key
business partners and suppliers to deliver  information and services due to Year
2000 problems.

Costs

The Company's  aggregate  spending in connection  with the Year 2000 Program was
approximately $28 million.  Certain of these costs were expensed as incurred and
funded through operating cash flow. The Company has expensed $6.9, $5.1 and $1.5
million in 1999, 1998 and 1997,  respectively.  The remainder of the $28 million
related to systems that the Company  anticipated  replacing in the normal course
of  information   technology   development  but  the  timetable  for  which  was
accelerated  in  contemplation  of the Year 2000 event.  Costs of replacement of
information  systems and  infrastructure  that would have occurred in the normal
course of business  without the advent of the Year 2000 event are excluded  from
these expensed amounts.


Insurance Coverage Issues

The Company continues to evaluate the potential  coverage  exposures arising out
of the Year 2000 event and its  impact on insured  equipment.  The  Company  had
filed with the various  jurisdictions an endorsement to its equipment  breakdown
forms which reiterated that coverage was not provided for the inherent inability
of computers and computerized  equipment to properly recognize a particular date
or time,  such as the year 2000. The endorsement was included in policies in all
states that approved the  endorsement.  In the four  jurisdictions  that did not
approve the endorsement, a notice reiterating the Company's coverage intent with
respect to Year 2000  exposures was sent to  policyholders.  The Company filed a
similar  endorsement for use with its all-risk policy. Many of the insurers that
the  Company   reinsures  for  equipment   breakdown   coverage  issued  similar
endorsements to their policies.

                                       42
<PAGE>

Although   reported   claim   activity  has  been   negligible   at  this  time,
quantification of the Company's exposure to Year 2000 losses and loss adjustment
expenses are not  reasonably  estimable  as  applicable  policy and  reinsurance
contract wordings have not been legally tested in the context of such losses.


Forward-Looking Statements

Certain statements contained in this report are forward-looking and are based on
management's  current  expectations.  Actual results may differ  materially from

the entry of new or  stronger  competitors  and the  intensification  of pricing
competition;  the loss of  current  customers  or the  inability  to obtain  new
customers;  changes in the  coverage  terms  selected  by  insurance  customers,
including  higher  deductibles and lower limits;  the adequacy of loss reserves;
changes in asset  valuations;  consolidation  and restructuring in the insurance
industry;   changes  in  the  Company's   participation  in  joint  underwriting
associations,  and in  particular  its new  agreement  with IRI;  changes in the

REPORT OF INDEPENDENT ACCOUNTANTS



To the Shareholders and Board of Directors of HSB Group, Inc.:

In our opinion, the consolidated financial statements listed in the accompanying
index present fairly, in all material  respects,  the financial  position of HSB
Group,  Inc. and its subsidiaries at December 31, 1999 and 1998, and the results

period ended December 31, 1999, in conformity with generally accepted accounting
principles.  In addition,  in our opinion,  the  financial  statement  schedules
listed in the accompanying index present fairly, in all material  respects,  the

consolidated  financial  statements.  These  financial  statements and financial
statement  schedules are the  responsibility  of the Company's  management;  our
responsibility  is to  express  an opinion  on these  financial  statements  and

Notes to Consolidated Financial Statements
(in millions, except per share amounts)


1. Accounting Policies


Consolidation

The accompanying  financial statements present the consolidated  accounts of HSB
Group,  Inc.  and its  subsidiaries  (collectively,  HSB or the Company) and are
prepared in accordance  with Generally  Accepted  Accounting  Principles  (GAAP)
within the U.S.  Significant  intercompany  transactions  and balances have been
eliminated  in  consolidation.   The  preparation  of  financial  statements  in
accordance  with GAAP requires the use of estimates in reporting  certain assets
and  liabilities.  Actual  results  could differ from those  estimates.  Certain
amounts  for 1998 and 1997  have  been  reclassified  to  conform  with the 1999
presentation.


Insurance

Insurance premium revenues are net of reinsurance ceded and are generally earned
on a pro rata basis over the  contract  period.  The portion of gross  insurance
premiums  not earned at the end of the period is recorded as unearned  insurance
premiums on the Consolidated Statements of Financial Position.

Prepaid acquisition costs, consisting principally of commissions,  premium taxes
and  certain  underwriting  expenses  are  amortized  as the  related  insurance
premiums are earned. Unearned ceded commissions arising from certain reinsurance
transactions  are netted in prepaid  acquisition  costs.  All other  acquisition
costs are charged to operations as incurred.

Liabilities  for  claims and  adjustment  expenses  for  boiler  and  machinery,
property  and  other  coverages  represent  estimated  reserves  on  claims  and
adjustment  expenses  reported  but not yet  settled  and the cost of claims and
adjustment  expenses  incurred  but not yet  reported.  Reserves  for claims and
adjustment  expenses are undiscounted and are gross of amounts  recoverable from
reinsurers.   Reserves  are  reduced  for  estimated   amounts  of  salvage  and
subrogation  and  deductibles  from  customers.  HSB  records  subrogation  when
recoverability  is probable,  such as when a judgment is returned,  liability is
admitted or settlement  is reached.  The length of time that reserves for claims
and adjustment expenses are carried on the Consolidated  Statements of Financial
Position  is a function  of the pay-out  patterns  associated  with the types of
coverages involved.  Estimates for these reserves reflect such variables as past
loss experience,  changes in judicial interpretation of legal liability,  policy
coverage and inflation.  The establishment of such reserves  frequently requires
complex engineering  judgements.  Due to the nature of the variables involved in
the  reserving  process,   subjective   judgments  are  an  integral  component.
Previously estimated reserves are regularly adjusted as loss experience develops
and new information  becomes  available.  Since reserves are based on estimates,
the ultimate  liability may be more or less than such  reserves.  The effects of
changes in estimated  reserves are included in the results of  operations in the
period in which the estimates change (see note 11).

Reinsurance  assets  represent  amounts due from  reinsurers for paid and unpaid
claims,  paid and unpaid loss  adjustment  expenses and the unearned  portion of
premiums ceded through reinsurance agreements.


Engineering Services

HSB recognizes the majority of its engineering  services revenues as the service
is provided.  Costs on such  contracts  are included in  operations as incurred.
Provisions  are made for  losses on  contracts  at the time such  losses  become
known.

                                       52

Investments

Cash and cash  equivalents  include cash on hand and  short-term  highly  liquid
investments with maturities of three months or less. Short-term investments have
a maturity  of one year or less and are  carried at cost  which,  together  with
accrued interest  thereon,  approximates  fair value.  Fixed maturities  include
bonds, notes and redeemable  preferred stocks.  Equity securities include common
and non-redeemable  preferred stocks. All fixed maturities and equity securities
are classified as available for sale. Accordingly, these investments are carried
at estimated  fair value.  Estimated  fair values of  securities  classified  as
available for sale are based  principally upon quoted market prices.  Unrealized
gains and losses on  investments  classified  as available  for sale and foreign
exchange gains and losses on certain investments in foreign operations where the
U.S.  dollar is not the  functional  currency  are included net of income tax in
shareholders' equity.

Investment income is net of investment  expenses.  Realized investment gains and
losses are  determined on the basis of costs related to those  investments  sold
and are recorded on the trade date. Also,  included in realized investment gains
and  losses  are  losses  arising  from  declines  in the  realizable  value  of
investments considered to be other than temporary.

The carrying  values of short-term  investments,  investment  income accrued and
securities transactions in the course of settlement approximate their fair value
because  of the  relatively  short  period of time  between  origination  of the
instruments and their expected realization.

Financial  instruments which qualify for hedge accounting are recorded at market
with gains and losses  reflected  in  shareholders'  equity.  To the extent such
instruments  do not qualify for hedge  accounting,  related gains and losses are
reflected in results of operations.


Income Taxes

Deferred  tax assets  and  liabilities  are  generally  determined  based on the
difference  between  financial  statement  and tax basis for certain  assets and
liabilities  using tax rates in effect for the year in which the differences are
expected to reverse.  Deferred tax assets are allowed if future  realization  is
more  likely  than not.  Deferred  income  taxes  are  provided  for  unrealized
appreciation/depreciation  on fixed maturities and equity  securities  available
for  sale,  prepaid  acquisition  costs,  loss  reserve  discounting,   unearned
premiums, certain employee benefit costs and other items which are the result of
temporary  differences  in the  treatment  of such  items for tax and  financial
statement purposes (see note 12).


Fixed Assets

Fixed assets include real and personal property and certain eligible capitalized
system  development  costs.  Fixed  assets are carried at cost less  accumulated
depreciation  and  amortization.  Depreciation and amortization is calculated on
the basis of estimated useful lives using straight-line and accelerated methods.
Upon  retirement  or  replacement,  any gain or loss is  included  in results of
operations.


Goodwill and Other Intangible Assets

Goodwill  represents  the cost of acquiring a business which is in excess of the
fair value of its net assets. Goodwill is generally amortized over 3 to 20 years
and other intangible assets over their estimated useful lives.  These assets are
included in other assets on the  Consolidated  Statements of Financial  Position
and amounted to $56.7 and $57.7  million  (net of  accumulated  amortization  of
$12.5  and $5.5  million)  at  December  31,  1999 and 1998,  respectively.  HSB
evaluates the  realizability  of goodwill based upon projections of undiscounted
cash flows.

2. Changes in Accounting Principles

The  Accounting  Standards  Executive  Committee  of the  American  Institute of
Certified Public Accountants  (AcSEC) issued three Statements of Position (SOPs)
that became  effective for fiscal years  beginning  after December 15, 1998: SOP
97-3,  "Accounting  by Insurance  and Other  Enterprises  for  Insurance-Related
Assessments," SOP 98-1, "Accounting for the Costs of Computer Software Developed
or Obtained for Internal Use" and SOP 98-5,  "Reporting on the Costs of Start-Up
Activities."   Because  the  Company's   accounting  policies  were  already  in
compliance with these SOPs, the implementation of these statements had no impact
upon the results of operations, financial condition or cash flows.

In June 1998, the Financial  Accounting  Standards Board (FASB) issued Statement
of Financial  Accounting  Standards  (SFAS) No. 133,  "Accounting for Derivative
Instruments and Hedging Activities"  subsequently  amended by SFAS No. 137. This
statement   establishes   accounting  and  reporting  standards  for  derivative
instruments,   including  certain  derivative   instruments  embedded  in  other
contracts  and for hedging  activities.  It  requires  that all  derivatives  be
recognized  as either  assets  or  liabilities  in the  statement  of  financial
position and that such  instruments be measured at fair value. In addition,  all
hedging relationships must be designated,  reassessed and documented pursuant to
the  provisions of SFAS No. 133. This statement is effective for the Company for
the first quarter of 2001. Based on the Company's  current  investment  policies
and practices,  the Company  anticipates  that the adoption of the provisions of
SFAS No.  133 will not have a  significant  effect  on  results  of  operations,
financial condition or cash flows.

In October 1998,  AcSEC issued SOP 98-7,  "Deposit  Accounting:  Accounting  for
Insurance and Reinsurance  Contracts That Do Not Transfer  Insurance  Risk." The
SOP identifies  several methods of deposit  accounting and provides  guidance on
the  application  of each  method.  This  SOP  became  effective  for  financial
statements for fiscal years beginning after June 15, 1999. Currently the Company
is not  party  to any  contracts  that do not  comply  with  the  risk  transfer
provisions  of SFAS No.  113,  "Accounting  and  Reporting  for  Reinsurance  of
Short-Duration and Long-Duration Contracts," and, therefore, does not anticipate
the adoption of SOP 98-7 will have a material  impact on results of  operations,
financial condition or cash flows.


3. Corporate Activity

Acquisitions / Divestitures

Structural Integrity Associates

In July 1999,  The  Hartford  Steam  Boiler  Inspection  and  Insurance  Company
(HSBIIC) acquired Structural Integrity  Associates,  Inc.  (Structural) based in
San Jose,  California.  Structural is an  engineering  consulting and inspection
services firm specializing in the analysis, control and prevention of structural
and equipment failures. It offers a full array of services,  from inspection and
condition  assessment,  to  monitoring  and  remaining  life  analysis,  repair,
remediation and total risk management of critical equipment and structures.


HSB Industrial Risk Insurers

The reinsurance  agreements effective January 1, 1998 between HSBIIC,  Employers
Reinsurance  Corporation  (ERC) and Industrial Risk Insurers (IRI), as discussed
below,  were  terminated  with  respect to loss or  liabilities  arising  out of
occurrences  taking place on or after January 1, 2000. As a result,  HSBIIC will
no longer retain 85 percent of the equipment  breakdown insurance and 15 percent
of the property insurance of the combined insurance  portfolio for risks arising
on or after January 1, 2000. The joint  underwriting  association that was known
as HSB  Industrial  Risk  Insurers  will,  from  January  1,  2000,  be known as
Industrial Risk Insurers (IRI).

                                       54
<PAGE>

Concurrent with the termination of the reinsurance  agreements,  HSBIIC, ERC and
IRI replaced the operating  agreement  dated January 1, 1998. The new agreement,
effective  January 1, 2000,  calls for HSBIIC to retain 0.5  percent  membership
share in IRI with the ability to increase  its total share up to a maximum of 10
percent,  at no cost,  at HSBIIC's  option.  In  addition,  the  agreement  also
establishes  an  arrangement  for  HSB to  perform  engineering  and  inspection
services for clients of IRI and  provides for a fixed  fronting fee in the event
that IRI continues to use HSBIIC's  licenses.  HSBIIC  received  payments of $27
million  in  December  1999  related  to  the  partial  settlement  of  unearned
reinsurance  premiums and ceding  commissions due to HSBIIC under the agreement.
Final settlement is expected to occur in the second half of 2000.

On January 6, 1998,  HSBIIC sold its interest in IRI to ERC in accordance with a
previously   announced  purchase  and  sale  agreement  between  ERC  and  IRI's
twenty-three  member insurers.  HSBIIC received gross proceeds of $49.1 million,
prior to transaction  costs,  for its 23.5 percent share in IRI. The gain on the
sale of IRI was $36.6 million pre-tax and $23.8 million  after-tax.  Because the
sale was structured in part as a reinsurance transaction,  a portion of HSBIIC's
gross proceeds was utilized to reinsure in-force policies with ERC.

IRI  is  an  unincorporated,  voluntary  joint  underwriting  association  which
provides property  insurance for the class of business known as Highly Protected
Risks (HPR) for larger  manufacturing,  processing  and  industrial  businesses,
which have invested in protection against loss through the use of sprinklers and
other means.  IRI primarily  writes policies on a syndicate basis that specifies
to the  insured  the  percentage  share of risk  accepted  by each member of the
association.  Each member  company,  therefore,  operates as a direct insurer or
reinsurer on such policies and participates in the premiums and losses generated
thereunder in proportion to its membership interest.  In 1997 and 1996, HSBIIC's
membership shares were 23.5 and 14 percent  respectively;  in 1995 and prior the
shares were 0.5 percent.

Contemporaneous with the close of the sale, IRI was reconstituted with ERC (with
a 99.5 percent share) and HSBIIC (with a 0.5 percent share) as the sole members.
The new association  had been renamed HSB Industrial Risk Insurers.  In 1999 and
1998,  HSBIIC wrote the  business for HSB  Industrial  Risk  Insurers  using its
insurance licenses and provided certain other management and technical services.
In addition, through various quota share reinsurance agreements with ERC and HSB
Industrial Risk Insurers,  HSBIIC transferred its manufacturing book of business
to HSB  Industrial  Risk  Insurers  and  retained  85 percent  of the  equipment
breakdown  insurance  and 15 percent of the  property  insurance of the combined
insurance portfolio.

To support HSB's expanded role, on December 31, 1997, a business trust formed by
HSB sold $300 million of 20 year, 7 percent  Convertible Capital Securities in a
private placement to ERC (see note 13). These capital securities are convertible
into HSB  common  stock,  at any time,  subject  to  regulatory  approval,  at a
conversion  price of  $56.67  per  share.  $250  million  of the  proceeds  were
contributed to HSBIIC and $50 million were retained by HSB.


Radian LLC

On January 2, 1998,  HSBIIC  exercised its option to put its 40 percent share in
Radian  International  LLC (Radian LLC) to The Dow Chemical  Company (Dow),  for
approximately  $129 million,  net of expenses.  Radian LLC was formed in January
1996  as a  joint  venture  with  Dow  to  provide  environmental,  engineering,
information  technology,  remediation and strategic chemical management services
to industries and governments worldwide. In connection with the formation of the
new company, HSBIIC contributed  substantially all of the assets and liabilities
of its wholly owned subsidiary, Radian Corporation to Radian LLC. The results of
Radian LLC were classified as discontinued  operations following ratification on
July 28, 1997 by HSB's Board of Directors of  management's  decision to exercise
its put.  HSBIIC's  share of Radian LLC's  losses  incurred  subsequent  to such
decision of approximately  $6.6 million after-tax was deferred and recognized at
the time the gain was  recognized  in  1998.  This  transaction  resulted  in an
after-tax gain of approximately  $36.9 million,  which was recorded in the

                                       55
<PAGE>

first quarter of 1998. Prior to July 1997, HSBIIC's share of the joint venture's
results were recorded as equity in Radian LLC.

As of December 31, 1997, Radian LLC had assets of $159.7 million, liabilities of
$88.4 million,  revenues of $288.0 million and expenses of $314.0 million. As of
December 31, 1997, HSBIIC's interest in Radian LLC was 40 percent.


Kemper

HSBIIC completed an acquisition of the monoline boiler and machinery business of
Kemper  Insurance  Companies  (Kemper) and  Kemper's  ASME  inspection  services
business that certifies boiler and pressure vessel compliance with the codes and
standards of the American  Society of Mechanical  Engineers,  effective  July 1,
1998.  The two  companies  also  completed an  agreement  for HSBIIC to reinsure
boiler and machinery  coverage  written as part of Kemper's  commercial  package
policies.


Solomon Associates, Inc.

In April 1998,  HSB acquired  Solomon  Associates,  Inc.  (SAI) based in Dallas,
Texas.  SAI  is  an  engineering   management   consulting  firm  that  provides
comparative performance  benchmarking consulting to the refining,  petrochemical
and power generation industries.


Stock Split

On April 21, 1998, the Board of Directors  approved a three-for-two  stock split
for  shares  held of record on May 1,  1998.  Additional  shares of HSB's  stock
resulting from the split were  distributed  on May 22, 1998. In accordance  with
SFAS No. 128 "Earnings per Share"  (EPS),  all earnings per share  presentations
have  been  adjusted  to  reflect  the  impact  of the  stock  split,  including
retroactive  restatement  of prior  periods.  Shares have also been restated for
comparative purposes.


Capital Securities

On July 15, 1997, HSB sold $110 million of 30 year Global  Floating Rate Capital
Securities in a private placement. On December 31, 1997, HSB issued $300 million
of 20 year fixed rate Convertible Capital Securities to ERC (see note 13).

5. Segment Information

HSB has four reportable  segments - Commercial  insurance,  Global Special Risks
insurance, Engineering services and Investments. HSB is a multi-national company
operating primarily in North American,  European and Asian markets.  Through its
Commercial  segment  operations,   HSB  provides  risk  modification   services,
equipment   breakdown   insurance  and  loss  recovery  services  to  commercial
businesses.  The Global Special Risks operating  segment focuses on the needs of
equipment-intensive  industries by offering  all-risk  coverage with  customized
engineering   consulting  and  risk  management.   HSB's  Engineering   services
operations offer professional  scientific and technical  consulting for industry
and government on a worldwide basis. The Company's investment assets are managed
by its Investment operating segment.

The  accounting  policies of the  segments  are the same as those  described  in
"Accounting  Policies"  (see note 1), except for certain  benefit  charges which
comprise the Corporate  Account.  HSB evaluates the  performance of its

                                       57
<PAGE>

segments and  allocates  resources to them based on net income  (loss).  Segment
assets are not included in this evaluation process.  Interest income and expense
are included in the results of Investment operations.

HSB's foreign operations (primarily insurance) are widely dispersed such that no
country or logical  aggregation  of countries in a geographic  area  comprises a
significant  concentration  with  respect  to either  revenues  or  identifiable
assets.  Export  sales from HSB's  domestic  operations  are  minimal due to the
existence  of the  Company's  foreign  subsidiaries  which are  responsible  for
virtually all of the Company's foreign sales.

The  following  presents  financial  data of the  Company  based  on  geographic
location:

6. Statutory Financial Information

HSBIIC is a Connecticut domiciled insurance company which is licensed to conduct
business in all 50 states,  the District of  Columbia,  Puerto Rico and the U.S.
Virgin Islands. The annual statements for state insurance regulatory authorities
are currently  prepared using accounting methods prescribed or permitted by such
authorities  (statutory  basis) and are not consolidated.  Statutory  accounting
practices (SAP) also differ in certain other respects from GAAP. With respect to
HSBIIC,  these differences are primarily comprised of the accounting for prepaid
acquisition costs, deferred income taxes, fixed maturity investments,  valuation
of certain non-insurance  affiliates and employee benefit plans. At December 31,
1999 and 1998, policyholders' surplus on a statutory basis was $428.8 and $612.6
million, respectively. Statutory net income, adjusted to include the earnings of
all HSBIIC domestic  insurance  subsidiaries  for 1999, 1998 and 1997 was $81.1,
$202.5 and $42.9 million, respectively.

HSBIIC  and  its  insurance   subsidiaries  are  currently  subject  to  various
regulations  that limit the maximum  amount of  dividends  available to HSBIIC's
parent company without prior approval of insurance regulatory authorities. Under
SAP,   approximately   $80  million  of  statutory   surplus  is  available  for
distribution to HSB Group, Inc. in 2000 without prior regulatory approval.

In 1998, the National Association of Insurance  Commissioners (NAIC) adopted the
Codification of Statutory Accounting Principles guidance, which will replace the
current  Accounting  Practices  and  Procedures  manual  as the  NAIC's  primary
guidance on statutory accounting.  The NAIC is now considering amendments to the
Codification guidance that would be effective upon implementation.  The NAIC has
recommended  an effective date of January 1, 2001. The Company has not estimated
the potential  effect of the  Codification  guidance  adopted by the Connecticut
Insurance Department.

On December 19, 1996,  HSBIIC entered into three "zero cost collar contracts" to
mitigate the effects of market risk on its U.S. common stock  portfolio  (which,
for management purposes, included certain convertible preferreds). In the fourth
quarter of 1997,  HSBIIC settled all of its outstanding  contracts  resulting in
realized  losses of $30.7 million for the year,  all of which were offset by and
represented  portfolio  appreciation and returns that were realized.  During the
year ended  December 31, 1997,  the Company's  U.S.  common stock  portfolio had
experienced a total return of $57 million (which included price  appreciation of
approximately $54 million) and had a price movement correlation with the S&P 500
Index well in excess of 80 percent.

The collar  subjected the Company to market and  counterparty  credit risk.  The
Company  managed this exposure by  frequently  modeling the effects of potential
future  price  movements on the value of the collar and HSB's  portfolio  and by
entering into contracts with internationally  recognized financial institutions,
which  were  expected  to  perform  under  the  terms  of the  contract,  and by
evaluating  the credit  worthiness of such  institutions  by taking into account
credit ratings and other factors.

8. Fixed Assets

Fixed assets are summarized as follows:

At December 31,                                               1999       1998

Land and buildings                                         $   4.9    $   5.1
Furniture, equipment, leasehold improvements and other        72.8       68.0
Systems development costs                                     32.5       23.9
                                                         ---------------------
                                                             110.2       97.0
Less accumulated depreciation and amortization               (52.0)     (42.1)
                                                         ---------------------
   Total fixed assets                                      $  58.2    $  54.9
- ------------------------------------------------------------------------------

Property  and  equipment  are stated at cost.  Depreciation  expense is computed
using  straight-line and accelerated  methods over the estimated useful lives of
31.5  years  for  buildings  and 3 to 10  years  for  equipment  and  furniture.
Leasehold  improvements  are  amortized  over the shorter of the assets'  useful
lives or their remaining contractual lease terms.

The Company has a policy of  capitalizing  certain  systems  development  costs.
Systems  development  costs are amortized over estimated useful lives of 3 to 10
years. In 1998,  approximately $6.5 million of systems development costs related
to the allocation of purchase price for SAI.

In 1996, the Company began a  comprehensive  effort to assess and address issues
relating to the ability of its policy processing and other  operational  systems
to properly recognize calendar dates beginning in the year 2000. As part of this
effort,  the  Company  established  a Year 2000  Program to address the areas of
applications  software,  infrastructures,  embedded  technology and key business
partners and suppliers.  The Company's aggregate spending in connection with the
Year 2000 Program was  approximately  $28  million.  Certain of these costs were
expensed as incurred and funded  through  operating  cash flow.  The Company has
expensed $6.9, $5.1 and $1.5 million in 1999, 1998 and 1997,  respectively.  The
remainder  of the $28 million  related to systems  that the Company  anticipated
replacing in the normal course of  information  technology  development  but the
timetable for which was  accelerated  in  contemplation  of the Year 2000 event.
Costs of replacement of information  systems and infrastructure  that would have
occurred in the normal  course of  business  without the advent of the Year 2000
event are excluded from these amounts,  and are being  capitalized in accordance
with the Company's existing capitalization policy.


9. Leases

The  Company  leases  its home  office  facility  at One  State  Street  under a
long-term   capital  lease  with  the  One  State  Street  Limited   Partnership
(Partnership).  The lease  obligation  of $26.1  million was recorded at July 1,
1983 at an  interest  rate of 15  percent.  An asset of $26.1  million  was also
recorded  in 1983.  Accumulated  amortization  on the  asset was $12.3 and $11.5
million at December 31, 1999 and 1998, respectively.  Terms of the lease require
annual minimum lease payments of approximately  $4.2 million a year through June
30,  2018.  In  addition,  the  Company is required to pay over the lease term a
proportional share of the facility's variable operating expenses.  This amounted
to approximately  $2.7, $2.9 and $2.6 million for the years ended 1999, 1998 and
1997, respectively.

The Company owns the One State Street land and leases it to the Partnership. The
Company  receives a base rent for the land and a  participation  in the net cash
flow of the  Partnership.  If the facility is sold,  the Company will receive 50
percent or more of the sales proceeds in excess of the mortgages,  all operating
expenses  and  costs of sale and the  rental  obligations  pursuant  to the land
lease.  Under certain  circumstances,  the Company has the right to purchase the
facility.

                                       63
<PAGE>

In addition to its home office  facility,  the  Company  leases  facilities  and
certain  equipment which are accounted for as operating  leases.  Lease expenses
amounted to $12.0, $10.2 and $8.4 million in 1999, 1998 and 1997, respectively.

At December 31, 1999,  future minimum  rental  commitments  under  noncancelable
leases accounted for as operating leases with initial or remaining terms of more
than one year were as follows:

2000                       $ 6.9
2001                         6.3
2002                         5.7
2003                         5.1

   Assumed                                 371.0       361.7       239.2
   Ceded                                  (441.9)     (374.4)     (118.1)
                                      -----------------------------------
      Insurance premiums                $  381.9    $  396.1    $  491.2
- -------------------------------------------------------------------------

In 1999 and 1998,  HSBIIC was the direct writer of business written on behalf of
HSB  Industrial  Risk  Insurers.  This  business  was ceded to that  entity  and
HSBIIC's share of the equipment breakdown and property business was assumed back
in accordance  with the  reinsurance  agreements in place with ERC (see note 3).
This has  resulted  in  growth  in gross  and  ceded  premiums  and  claims  and
adjustment expenses.

The  Company  writes  direct  business,  which  in 1999 and  1998  included  HSB
Industrial  Risk Insurers  business,  through  agencies and brokerage  firms. In
addition,  the Company assumes boiler and machinery exposures from approximately
200  insurance  companies and several  insurance  pools.  Under the  reinsurance
agreements,  the Company's  reinsured  companies may include equipment breakdown
exposures in their multi-peril  policies,  and such risks will be assumed by the
Company under the terms of the agreement.  These  agreements  generally  provide
that the Company  will assume 100  percent of each  boiler and  machinery  risk,
subject to the capacity specified in the agreement,  and will receive the entire
equipment  breakdown  premium  except  for a ceding  commission,  which  will be
retained by the reinsured company for commissions to agents and brokers, premium
taxes and handling expenses.

Although the Company assumes the role of reinsurer, it continues to have selling
and  underwriting  responsibilities  as well as  involvement  in inspecting  and
claims  adjusting.  In effect,  the  Company  becomes  the  equipment  breakdown
insurance  department  of the  reinsured  company  and  provides  all  equipment
breakdown  underwriting  (that is, the  examination  and  evaluation of the risk
based on its engineering  judgments),  claims and engineering  services as if it
were  part  of that  organization.  Traditionally,  as part of the  underwriting
process,  the Company  retains the right to decline or restrict  coverage in the
same manner as it does for its own business. In 1996, the Company began to write
a simplified  program  (referred to as ReSource) under which a reinsured company
agrees

                                       64
<PAGE>

to include  equipment  breakdown  insurance  on an entire  portfolio of accounts
meeting specific  underwriting  guidelines and occupancy  parameters,  which the
Company agrees to reinsure for equipment breakdown losses.

The  insurance   industry,   in  general,   continues  to  undergo   significant
restructuring and consolidation.  Considerable  merger and acquisition  activity
has  occurred  over the last  several  years and,  with the advent of  financial
services reform,  more  contraction is possible in the future.  Depending on the
specific  companies  involved in these activities and other market factors,  the
level of reinsured business the Company assumes in the future could be impacted.

For 1999 approximately 26 percent of the Company's gross written premium,  which
includes HSB Industrial Risk Insurers,  was produced by J&H Marsh & McLennan and
Sedgwick Group.

As a property  insurer,  the  Company  is subject to losses  that may arise from
catastrophic  events.  The Company  participates in various  facultative,  quota
share  and  excess  of  loss  reinsurance  agreements  to  limit  its  exposure,
particularly to catastrophic losses, and to provide additional capacity to write
business.  In the unlikely event that ceded  reinsurers are unable to meet their
obligations,   the  Company  would   continue  to  have  primary   liability  to
policyholders for losses incurred.  Reinsurance recoverable on unpaid claims and
the  unearned  portion of ceded  reinsurance  premiums  are  reported as assets,
rather than netted against the related  liability  accounts.  The Company is not
party to any contracts which do not comply with the risk transfer  provisions of
SFAS No. 113,  "Accounting and Reporting for Reinsurance of  Short-Duration  and
Long-Duration  Contracts." The Company recorded $503.4, $444.7 and $45.2 million
of reinsurance  recoveries as a reduction of its claims and adjustment  expenses
for the years ended December 31, 1999, 1998 and 1997, respectively.  Reinsurance
recoverable on paid claims and  adjustment  expenses was $22.9 and $14.6 million
at December 31, 1999 and 1998, respectively.

The Company utilizes  well-capitalized  domestic and  international  reinsurance
companies  and  syndicates  for  its  reinsurance  program  and  monitors  their
financial condition on an on-going basis. For reinsurers that are not accredited
in their state of domicile,  the Company  requires  collateral  for  reinsurance
recoverable from such carriers.  Uncollectible reinsurance recoverables have not
had,  and are not  expected  by  management  to have in the  future,  a material
adverse effect on the consolidated  results of operations or financial  position
of the Company.

* Net of business assumed by HSB from ERC


As of December  31,  1999,  no other  reinsurance  asset of the Company from any
single reinsurer exceeded 3.0 percent of shareholders'  equity.  Certain Lloyd's
syndicates  participate in the excess of loss reinsurance program,  primarily in
the excess  layers.  The  highest  aggregate  percentage  participation  of such
syndicates, at 32.4 percent,

                                       66
<PAGE>

is in the $50 million excess of $100 million layer. No individual  syndicate has
more than 7.2 percent  participation  in any of the excess layers.  In addition,
certain syndicates participate in three of our quota share treaties, aggregating
10.6, 12.7 and 82.9 percent in each of the three treaties. Lloyd's participation
in our catastrophe cover is 71.4 percent with no individual  syndicate retaining
more than 6.7 percent.  The Company's  reinsurance  asset in the aggregate  from
over 100 Lloyd's  syndicates,  excluding the syndicate  disclosed  above,  is 12
percent of shareholders'  equity at December 31, 1999.  Lloyd's has historically
participated more heavily in the higher treaty layers.

The  Company  is  involved  in  various  legal   proceedings   as  defendant  or
co-defendant  that have  arisen in the  normal  course of its  business.  In the
judgment of management,  after consultation with counsel,  it is improbable that
any  liabilities  which may  arise  from such  litigation  will have a  material
adverse  impact on the results of operations  or the  financial  position of the
Company.

Short-term and Long-term Borrowings

HSBIIC has a commercial  paper  program with a limit of $75 million.  Commercial
paper  outstanding  at December  31, 1999 and 1998 was $38.6 and $20.0  million,
respectively. The weighted-average interest rate was 6.0 percent and 5.2 percent
at December 31, 1999 and 1998,  respectively.  Commercial  paper  outstanding at
year end 1999

                                       68

matures on or before March 14, 2000.  Long-term  debt includes  $25.1 million of
senior  notes due May 15,  2000 at an  interest  rate of 6.83  percent.  Current
market value is estimated to be $25.3 million.


Capital Securities

On July 15, 1997, a trust  sponsored and wholly owned by the Company issued $110
million  aggregate  liquidation  amount  of  capital  securities  in  a  private
placement and 3,403 shares of common securities to the Company,  the proceeds of
which were invested by the trust in $113.4 million aggregate principal amount of
the  Company's  debt  securities.  On  November 5, 1997,  an exchange  offer was
commenced,  pursuant to which the capital  securities  originally  issued in the
private  placement were exchanged for capital  securities  that were  registered
with the Securities and Exchange  Commission  (the Capital  Securities)  and the
debt securities were exchanged for debt securities that were registered with the
Securities and Exchange Commission (the Debt Securities).

The Debt Securities  represent all of the assets of the trust. The proceeds from
the  issuance  of the Debt  Securities  were  used by the  Company  for  general
corporate purposes. The Debt Securities and related income statement effects are
eliminated  in the  Company's  consolidated  financial  statements.  The  $113.4
million  principal amount of Debt Securities  accrue and pay cash  distributions
quarterly  in  arrears  at a  variable  rate equal to the 90 day LIBOR plus 0.91
percent of the stated  liquidation  amount of $1,000 per Debt  Security  and are
scheduled to mature on July 15, 2027.

The Capital Securities accrue and pay cash distributions quarterly in arrears at
a  variable  rate  equal to the 90 day LIBOR  plus 0.91  percent  of the  stated
liquidation  amount of $1,000 per Capital  Security.  The current  coupon is 7.1
percent.  HSB has the right to defer payment of  distributions on the securities
at any time or from  time to time  for a period  not  exceeding  20  consecutive
quarterly  periods with  respect to each  deferral  period.  During an extension
period,  interest  will  continue to accrue and the amount of  distributions  to
which holders of the Capital  Securities are entitled will  accumulate,  and the
Company will be prohibited from paying any cash dividends on its common stock.

The Capital  Securities  are generally  non-callable  for ten years,  but may be
called earlier by HSB upon the  occurrence of certain tax events  including loss
of  deductibility  of interest on the  securities.  The Capital  Securities  are
mandatorily  redeemable  upon the  maturity of the Debt  Securities  on July 15,
2027,  or  earlier to the extent of any  redemption  by the  Company of any Debt
Securities.  The  redemption  price in either such case will be $1,000 per share
plus accrued and unpaid distributions to the date fixed for redemption.

The terms of the Debt  Securities,  the guarantee of the Company with respect to
the Capital Securities, the Indenture and the Trust Agreement together provide a
full guarantee of amounts due on the Capital Securities.  The Capital Securities
are  currently  rated BBB- by Standard & Poor's and BBB+ by Duff & Phelps credit
rating agencies.

On December 31, 1997, HSB Group,  Inc. sold $300 million of 20 year  Convertible
Capital  Securities  in a private  placement  to ERC.  The  Convertible  Capital
Securities are callable by the Company at its option (i) at any time after seven
years;  (ii)  upon the  occurrence  of  certain  tax  events  including  loss of
deductibility  of the  interest on the  securities;  (iii) in the event that HSB
vetoes a prospective purchaser of the Convertible Capital Securities; or (iv) in
the event of a change in control of ERC. The Convertible  Capital Securities are
mandatorily  redeemable  on December 31, 2017 and are  redeemable  at par plus a
redemption premium, at the option of ERC, in the event of a change in control of
HSB within five years following issuance of the securities.

The  Convertible  Capital  Securities are  convertible,  in whole or in part, at
ERC's option at any time,  subject to  regulatory  approval,  into shares of HSB
common stock at a conversion  price of $56.67 per share,  subject to adjustment.
HSB has  provided  certain  registration  rights to ERC in  connection  with the
common  stock into which the  Convertible  Capital  Securities  are  convertible
pursuant to a Registration Rights Agreement dated December 31,

                                       69
<PAGE>

1997. If ERC were to exercise its conversion  rights in total,  it would hold at
December 31, 1999, on a fully diluted basis, approximately 15.4 percent of HSB's
common stock. Pursuant to certain provisions contained in the Purchase Agreement
dated  December 31, 1997,  ERC has agreed to certain  "standstill"  arrangements
which for a period of five years will  preclude ERC from  purchasing  any common
stock of HSB,  other than by exercise of its conversion  rights,  and will limit
its  ability to take  certain  other  actions  with  respect to HSB during  that
period.

The  securities  were  issued  through  HSB  Capital  II (Trust  II), a Delaware
business trust created by HSB, at a 7 percent coupon, payable semi-annually. The
Convertible  Capital  Securities  rank pari passu with the Global  Floating Rate
Capital  Securities  issued  July  1997.  Holders  of  the  Convertible  Capital
Securities   will  be  entitled   to  receive   preferential   cumulative   cash
distributions  accumulating  from  the date of  original  issuance  and  payable
semi-annually in arrears.  HSB has the right to defer payment of interest at any
time or from time to time for a period not exceeding 10 consecutive  semi-annual
periods  with  respect to each  deferral  period.  During an  extension  period,
interest  will  continue  to accrue  and the  amount of  distributions  to which
holders of the Convertible Capital Securities are entitled will accumulate,  and
HSB will be prohibited  from paying any cash dividends on its common stock.  HSB
has irrevocably  and  unconditionally  guaranteed all of Trust II's  obligations
under the Convertible Capital Securities.

The estimated fair value of the Capital Securities issued by Trust I is equal to
their  carrying  value.  The  estimated  fair value of the  Convertible  Capital
Securities issued by Trust II is $272.2 million and is calculated without giving
any effect to the  relationship  of the  conversion  price to the current market
price of HSB Group, Inc. common stock.

14. Pension and Other Benefit Programs

HSB maintains various types of pension and postretirement medical plans covering
employees  of the  Company  and  certain  subsidiaries.  The  pension  plans are
non-contributory  and benefits are based upon an employee's years of service and
final average pay based upon the highest three out of five years. Vesting occurs
after five years of service in compliance  with the provisions of the Tax Reform
Act of 1986.

Under  the  terms of the HSB  Group,  Inc.  Thrift  Incentive  Plan,  a  defined
contribution  plan, covered employees are allowed to contribute up to 15 percent
of their pay, on a pre-tax basis,  limited by the maximum allowed under Internal
Revenue  Service  regulations.  The Company makes a matching  contribution of 50
percent of employee contributions up to 6 percent of compensation. Total expense
for the plan  was  $2.4,  $2.1  and  $1.7  million  for  1999,  1998  and  1997,
respectively.

The Company makes available health care and life insurance  benefits for retired
employees  of  the  Company  and  certain   subsidiaries.   The  Company   makes
contributions  to the plans as claims are incurred.  Retirees'

                                       70
<PAGE>

contributions  to these plans vary,  based upon  retiree's age, years of service
and coverage  elected.  The Company  periodically  amends the plan  changing the
contribution rate of retirees and amounts of coverage.

The following chart summarizes the balance sheet impact,  as well as the benefit
obligations, assets, funded status and rate assumptions associated with the U.S.
pension and postretirement medical benefit plans:

15.  Stock Compensation Plans

HSB has a Stock Option Plan under which key employees may be granted  restricted
stock and stock options.

HSB's Long-Term  Incentive Plan grants senior  management awards contingent upon
achievement of specified performance  objectives over a three year period, which
may be paid out in cash or shares  of  common  stock  (which  may be  restricted
shares).  The number of shares subject to issuance under this plan cannot exceed
375,000.

HSB's  restricted  stock is an award of  common  shares  that may not be sold or
transferred during the restriction  period,  usually three years under the Stock
Option Plan and five years under the Long-Term  Incentive Plan, from the date on
which the award is granted.  During the restriction  period, the employee is the
registered  owner,  receives  dividends  and may  vote  the  restricted  shares.
Compensation  expense is based on the market value of the Company's common stock
at the date of grant  and is  recognized  over the  period  of the  restriction.
Compensation  expense for this benefit was $3.7,  $1.0 and $0.6 million in 1999,
1998 and 1997,  respectively.  The unamortized  compensation  expense related to
this plan is included in benefit plans as a component of  shareholders'  equity.
These amounts were $6.9 and $2.2 million in 1999 and 1998, respectively.

A summary of grants follows:

                                            1999         1998         1997

- ---------------------------------------------------------------------------

A stock  option  award under the HSB's Stock Option Plan allows for the purchase
of HSB  common  stock at no less  than the  market  price on the date of  grant.
Options granted to date are exercisable no earlier than one year after the

                                       72

grant date and expire no more than ten years from the date of grant.  The number
of shares available for delivery under this plan cannot exceed 4.2 million.

SFAS No. 123, "Accounting for Stock Based Compensation" allows the use of a fair
value based method of accounting  for an employee stock option or similar equity
instruments  or the  intrinsic  value  based  method  prescribed  by  Accounting
Principals Board Opinion No. 25, "Accounting for Stock Issued to Employees" with
pro forma  disclosures of net income and earnings per share as if the fair value
based method of accounting had been applied. The Company has elected to continue
using the  intrinsic  value based method.  Had the Company  elected to recognize
compensation  cost using the fair value based  method,  compensation  would have
been measured at date of grant and recognized over the service period. Pro forma
net income and earnings per share would have been imputed as follows:

16. Stock Purchase Rights

On  September  21, 1998,  the Board of Directors  approved the adoption of a new
shareholder  rights  plan to replace the plan that was set to expire on November
28, 1998.  Pursuant to the new plan, which is  substantially  similar to the old
plan, the Board declared a dividend of one right for each  outstanding  share of
common stock to shareholders of record on November 28, 1998.

The rights  will  separate  from the common  stock and become  exercisable  if a
person or group  acquires  ownership  of 15 percent  or more of the  outstanding
common stock of the Company or  commences a tender or exchange  offer to acquire
15 percent or more of the outstanding shares.

Each right entitles a holder to purchase one  two-hundredth of a share of Series
A Junior  Participating  Preferred Stock, without par value at an exercise price
of $162.00 per share,  subject to adjustment.  If an acquirer obtains 15 percent
or more of the Company's common stock and the Board of Directors determines that
such acquisition is not in the best interest of the shareholders,  the rights of
shareholders  other than the acquirer will entitle the holder to purchase common
shares of the Company (or, under certain circumstances, of the acquirer) at a 50

(1) Fourth quarter  results  reflect  pre-tax  charges of $5 million  related to
change  in  management  costs  and   consolidation  and  relocation  of  certain
businesses  as well  as $7  million  in  losses  related  to  medical  equipment
insurance contracts.

(2) In the fourth quarter,  the assumed conversion of the Company's  convertible
capital  securities is not used in the  computation  of earnings per share since
such inclusion  would be  antidilutive.  Therefore,  the quarterly  earnings per
share will not equal the full year earnings per share.

                                     BYLAWS
                                       of
                                 HSB GROUP, INC.

                                    ARTICLE I
                             SHAREHOLDERS' MEETINGS

         All meetings of the Shareholders  shall be held in the City of Hartford
or such other place within  Connecticut  as the Board of Directors  may appoint.
The Annual  Meeting shall be held on the 3rd Tuesday of April in each year or on
some  other  day  within  two (2)  months  thereafter  as fixed by the  Board of
Directors.  Special  meetings  of the  Shareholders  may be held at such time as
fixed by the Board of Directors. Notice of every meeting of the Shareholders and
of the time and place thereof shall be given as required by law. At each meeting
of the Shareholders the President or Chairman of the Board shall preside and act
as Chairman.  The Chairman may appoint a Committee on Proxies to receive,  count
and report the votes cast in person at such meeting and the votes represented by
proxies.  The holders of a majority of the shares of the issued and  outstanding
stock entitled to vote at a meeting, present either in person or by proxy, shall
constitute  a quorum for the  transaction  of  business  at such  meeting of the
Shareholders.  If a quorum is not  present  at such  meeting,  the  Shareholders
present in person or by proxy may adjourn to such future time as shall be agreed
upon by them, and notice of such adjournment  shall be given to Shareholders not
present or represented at the meeting.

         Regulations  for  the  conduct  of a  meeting  of  Shareholders  may be
prescribed  by the  Chairman  or at the  Chairman's  option  be  adopted  by the
Shareholders present by voice vote or by ballot.

         At any meeting of the Shareholders, only such business may be conducted
as shall have been  properly  brought  before the meeting and as shall have been
determined to be lawful and appropriate for consideration by Shareholders at the
meeting.  To be properly brought before a meeting business must be (a) specified
in the notice of meeting,  (b) otherwise  properly brought before the meeting by
or at the direction of the Board of Directors or the Chairman of the meeting, or
(c) otherwise properly brought before the meeting by a Shareholder. For business
to be properly brought before a meeting by a Shareholder  pursuant to clause (c)
above,  the Shareholder  must have given timely notice thereof in proper written
form to the Corporate  Secretary.  To be timely,  a Shareholder's  notice to the
Corporate Secretary must be delivered to or mailed and received by the Corporate
Secretary  of the Company not less than sixty nor more than ninety days prior to
the anniversary of the date on which the immediately preceding Annual Meeting of
the Shareholders  was convened;  provided,  however,  that in the event that the
Annual  Meeting is called for a date that is not within  thirty  days  before or
after such  anniversary  date,  notice by the  Shareholder in order to be timely
must be received not later than the close of business on the tenth day following
the day on which  such  notice of the date of the Annual  Meeting  was mailed or
such public  disclosure  of the date of the Annual  Meeting was made,  whichever
first occurs.  Such  Shareholder's  notice shall set forth as to each matter the
Shareholder  proposes to bring before the meeting (a) a brief description of the
business desired to be brought before the meeting and the reasons for conducting
such  business  at the  meeting,  (b)  the  name  and  record  address  of  such
Shareholder,  (c) the class and number of shares of capital stock of the Company
which are beneficially held by such Shareholder and (d) any material interest of
such Shareholder in such business.  Notwithstanding  anything in these Bylaws to
the contrary,  no business  shall be conducted at a meeting except in accordance
with the procedures set forth herein.  The Chairman of the meeting shall, if the
facts  warrant,  determine  and declare to the  meeting  that  business  was not
properly  brought before the meeting in accordance with the procedures set forth
herein,  or that business was not lawful or  appropriate  for  consideration  by
Shareholders  at the  meeting,  and if the  Chairman  of the  meeting  should so
determine,  the Chairman of the meeting  shall so declare to the meeting and any
such business not properly brought before the meeting shall not be transacted at
that meeting.

         Nominations  of persons for  election to the Board of  Directors of the
Company may be made by the Board of Directors or by any Shareholder  entitled to
vote for the election of Directors in compliance with the notice  procedures set
forth herein. Any Shareholder  entitled to vote for the election of Directors at
a meeting may  nominate  persons for the  election of  Directors  only if timely
written notice of such Shareholder's intent is given to the Corporate Secretary.
To be  timely,  a  Shareholder's  notice  to the  Corporate  Secretary  must  be
delivered  to or mailed and received by the  Corporate  Secretary of the Company
not less than sixty days nor more than ninety days prior to the  anniversary  of
the date on which the immediately  preceding  Annual Meeting of the Shareholders
was convened;  provided,  however,  that in the event that the Annual Meeting is
called  for a date  that  is  not  within  thirty  days  before  or  after  such
anniversary  date,  notice  by the  Shareholder  in order to be  timely  must be
received not later than the close of business on the tenth day following the day
on which such notice of the date of the Annual Meeting was mailed or such public
disclosure of the date of the Annual Meeting was made,  whichever  first occurs.
Such  Shareholder's  notice  shall  set  forth  (a) as to each  person  whom the
Shareholder proposes to nominate for election or re-election as a Director,  (i)
the name, age, business address and residence  address of such person,  (ii) the
principal occupation or employment of such person, (iii) the class and number of
shares of capital  stock of the  Company  which are  beneficially  owned by such
person and (iv) any other  information  relating to such person that is required
to be disclosed in  solicitations  of proxies for election of  Directors,  or is
otherwise required, in each case pursuant to Regulation 14A under the Securities
Exchange Act of 1934, as amended  (including,  without  limitation such person's
written  consent  to being  named in the proxy  statement  as a  nominee  and to
serving as a  Director  if  elected)  and (b) as to the  Shareholder  giving the
notice, (i) the name and address, as they appear on the Company's books, of such
Shareholder  and,  (ii) the class and number of shares of  capital  stock of the
Company which are beneficially owned by such Shareholder. If the Chairman of the
meeting  determines  that a nomination was not in accordance  with the foregoing
procedures, such nomination shall be void.

                                   ARTICLE II
                                    DIRECTORS

         The Board of Directors  shall consist of the number of directors  fixed
from time to time by resolution adopted by the affirmative vote of a majority of
the entire Board of Directors. No person shall serve as Director beyond the date
of the first Annual Meeting of  Shareholders  held  subsequent to the Director's
seventieth birthday,  unless such Director's service is extended by a resolution
adopted by a majority of the Board of Directors.  Such resolution  shall specify
the date to which  service is  extended  which in no event may be later than the
last day of the Director's then current term.

         Regular and special meetings of the Board of Directors shall be held as
determined by the Directors.

         At any meetings of the Board of Directors,  a majority of the Directors
then in  office,  but not less  than  one-third  of the  directorships  fixed in
accordance with this Article,  shall  constitute a quorum for the transaction of
business. Unless otherwise prescribed herein or in the Articles of Incorporation
of the Company,  action of the Board of Directors  shall be by majority  vote of
the Directors present.  The compensation of Directors shall be determined by the
Board of Directors.


                                   ARTICLE III
                                   COMMITTEES


         The  Board  of  Directors  may by  resolution  designate  two  or  more
Directors to  constitute  an  executive  committee  or other  committees,  which
committees  shall  have and may  exercise  all such  authority  of the  Board of
Directors as shall be provided in such  resolution,  subject to such limitations
as are provided under Section 33-753 of the Connecticut General Statutes,  as it
may be amended from time to time.

         The  Board  of  Directors  may by  resolution  designate  one  or  more
Directors as  alternate  members of such  committees  who may replace any absent
member at any meeting of such  committees upon such notice and in such manner as
may be provided in the resolution designating such alternate members.


                                   ARTICLE IV
                                    OFFICERS

         There  shall be a  President  and there may be a Chairman of the Board,
each  elected by the Board of  Directors  from their own number.  The  President
shall be the chief executive  officer and responsible under the direction of the
Board of Directors for the  supervision,  management  and active  control of the
affairs and properties of the Company.

         The  Board  of  Directors  may  also  elect a  Corporate  Secretary,  a
Treasurer, one or more Executive Vice Presidents and Senior Vice Presidents.

         The President  shall appoint such other Officers as may be required for
the prompt and orderly transaction of the business of the Company.

          Any elected  Officer may be removed at the  pleasure of the  Directors
and any appointed Officer may also be removed by the President.

         The Officers  shall be subject to the  direction of and shall have such
authority  and perform  such duties as may be assigned  from time to time by the
Board of Directors or the President.

                                    ARTICLE V
                                   AMENDMENTS

majority of the entire Board of Directors at any meeting of said Board, provided
that notice thereof shall have been given in the notice of such meeting.

                                                            Exhibit 10(iii)(b)



                               SEVERANCE AGREEMENT


                  THIS  AGREEMENT,  dated  November  29,  1999,  is  made by and
between HSB Group, Inc., a Connecticut corporation (the "Company"),  and Richard
H. Booth (the "Executive").

                  WHEREAS,  the Company  considers it essential to the best
interests of its shareholders to attract and retain key executives; and

                  WHEREAS,  the Board  recognizes that, as is the case with many
publicly held  corporations,  the  possibility of a Change in Control exists and
that such  possibility,  and the  uncertainty  and questions  which it may raise
among  management,  may result in the  departure or  distraction  of  management
personnel to the detriment of the Company and its shareholders; and

                  WHEREAS,  the  Board has  determined  that  appropriate  steps
should  be  taken  to  reinforce  and  encourage  the  continued  attention  and
dedication of members of the Company's management,  including the Executive,  to
their assigned duties without distraction in the face of potentially  disturbing
circumstances arising from the possibility of a Change in Control; and

                  WHEREAS, the Board desires to provide for a specific severance
benefit for certain terminations of employment unrelated to a Change in Control;

                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
mutual covenants herein contained, the Company and the Executive hereby agree as
follows:


                  1.  Defined  Terms.  The  definitions  of  capitalized  terms
used in this Agreement are provided in the last Section hereof.

                  2.  Term  of  Agreement.  The  Term of  this  Agreement  shall
commence on the date hereof and shall  continue in effect  through  December 31,
2002; provided,  however,  that commencing on January 1, 2001 and each January 1
thereafter,  the Term shall  automatically  be extended for one additional  year
unless,  not later than  September 30 of the preceding  year, the Company or the
Executive shall have given notice not to extend the Term; and further  provided,
however,  that if a Change in Control shall have occurred  during the Term,  the
Term shall expire no earlier  than  thirty-six  (36) months  beyond the month in
which such Change in Control occurred.

                  3.  Company's  Covenants  Summarized.  In order to induce  the
Executive  to remain in the employ of the  Company and in  consideration  of the
Executive's  covenants set forth in Section 4 hereof, the Company agrees,  under
the conditions described herein, to pay the Executive the Severance Payments and
the other payments and benefits  described  herein.  This Agreement shall not be
construed as creating an express or implied  contract of employment  and, except
as  otherwise  agreed in writing  between the  Executive  and the  Company,  the
Executive shall not have any right to be retained in the employ of the Company.

                  4. The  Executive's  Covenants.  The  Executive  agrees  that,
subject  to the  terms  and  conditions  of this  Agreement,  in the  event of a
Potential  Change in Control  during the Term,  the Executive will remain in the
employ of the Company  until the  earliest of (i) a date which is six (6) months
following  the date of such  Potential  Change  in  Control,  (ii) the date of a
Change  in  Control,  (iii)  the date of  termination  by the  Executive  of the
Executive's  employment  for Good  Reason or by reason of death,  Disability  or
Retirement, or (iv) the termination by the Company of the Executive's employment
for any reason.

                  5.  Compensation   Other  Than  Change  in  Control  Severance
Payments.

                  5.1 Following a Change in Control and during the Term,  during
any period that the Executive fails to perform the Executive's  full-time duties
with the Company as a result of  incapacity  due to physical or mental  illness,
the Company shall pay the  Executive's  full salary to the Executive at the rate
in effect at the commencement of any such period, together with all compensation
and benefits  payable to the Executive  under the terms of any  compensation  or
benefit  plan,  program or  arrangement  maintained  by the Company  during such
period,  until the  Executive's  employment  is  terminated  by the  Company for
Disability.

                  5.2 If the Executive's  employment shall be terminated for any
reason during the Term, the Company shall pay the Executive's full salary to the
Executive  through  the Date of  Termination  at the rate in effect  immediately
prior to the Notice of Termination or, in the event of a termination following a
Change in Control, such higher rate as may be in effect (i) immediately prior to
the Change in Control,  or (ii) immediately  prior to the first occurrence of an
event or circumstance constituting Good Reason in the event of a termination for
Good  Reason,  together  with  all  compensation  and  benefits  payable  to the
Executive  through  the Date of  Termination  under the  terms of the  Company's
compensation   and  benefit  plans,   programs  or  arrangements  as  in  effect
immediately prior to the Notice of Termination or, in the event of a termination
following  a Change in Control and if more  favorable  to the  Executive,  as in
effect (i) immediately prior to the Change in Control, or (ii) immediately prior
to the first occurrence of an event or circumstance  constituting Good Reason in
the event of a termination for Good Reason.

                  5.3 If the Executive's  employment shall be terminated for any
reason during the Term,  the Company shall pay to the Executive the  Executive's
normal  post-termination  compensation  and  benefits,  if any, as such payments
become due. Such post-termination  compensation and benefits shall be determined
under,  and paid in accordance  with,  the Company's  retirement,  insurance and
other  compensation  or benefit plans,  programs and  arrangements  as in effect
immediately prior to the Notice of Termination or, in the event of a termination
following  a Change in Control and if more  favorable  to the  Executive,  as in
effect (i) immediately prior to the Change in Control, or (ii) immediately prior
to the occurrence of the first event or circumstance constituting Good Reason in
the event of a termination  for Good Reason;  provided that, for purposes of any
retiree medical benefits  insurance  program then in effect,  Executive shall be
deemed to have satisfied any years of service and retirement status requirements
as of the Date of Termination in order to be eligible to receive  benefits under
such program.

                  5.4 If the Executive's  employment  shall be terminated by the
Company for any reason  (other than for death,  Disability  or Cause) during the
Term and the Executive is not entitled to any Severance  Payments as provided in
Section 6.1 hereof,  the Company shall pay to the Executive a severance payment,
in cash, equal to two times the Executive's base salary as in effect immediately
prior  to  issuance  of the  Notice  of  Termination  in  connection  with  such
termination,  payable in substantially equal bi-weekly installments over the two
year period  following  such  termination.  The Company  shall also  provide the
Executive with outplacement  services suitable to the Executive's position for a
period expiring three years after the Date of Termination, or, if earlier, until
the first  acceptance by the Executive of an offer of employment.  The severance
benefits  payable  under  this  Section  5.4  shall be in lieu of any  severance
benefits  otherwise payable to the Executive.  The Company shall also pay to the
Executive  all legal fees and expenses  incurred by the  Executive in seeking in
good faith to obtain or enforce  any benefit or right  provided by this  Section
5.4; provided, that such reimbursement shall only be payable if the Executive is
successful in obtaining or enforcing such benefit or right.

                  5.5 If the Executive's  employment shall be terminated for any
reason other than death during the Term, in addition to any retirement  benefits
to which the Executive is entitled under each Pension Plan or any successor plan
thereto,  the Company  shall pay the  Executive a benefit equal to the excess of
(i) the retirement pension to which the Executive would have been entitled under
the  Retirement  Plan  determined  as if the Executive  were fully  vested,  had
accumulated  ten (10)  additional  years of Credited  Service (as defined in the
Retirement  Plan),  and had "Earnings"  under such plan determined in accordance
with Exhibit A, over (ii) any vested  retirement  pension  under the  Retirement
Plan which the Executive had accrued  pursuant to the provisions of such plan as
of the Date of Termination.  The benefit payable under this Section 5.5.,  shall
commence  and be paid at the same time and in the same form as the  benefit,  if
any, payable under the Retirement Plan;  provided however,  if the Executive has
not vested in a benefit  under the  Retirement  Plan,  Executive  shall have the
right to select the commencement and form of payment to the same extent he would
were such benefit to be payable under the Retirement Plan.

                  5.6 If the  Executive's  employment  shall  be  terminated  on
account of death during the Term and the Executive is married at the time of his
death,  in addition to any death  benefits  to which the  Executive's  spouse is
entitled  under each Pension Plan or any  successor  plan  thereto,  the Company
shall  pay the  Executive's  spouse a  benefit  equal to the  excess  of (i) the
aggregate death benefit to which the Executive's spouse would have been entitled
under the Retirement Plan determined as if the Executive were fully vested,  had
accumulated  ten (10)  additional  years of Credited  Service (as defined in the
Retirement  Plan) and had  "Earnings"  under such plan  determined in accordance
with Exhibit A, prior to his death over (ii) any  aggregate  death benefit under
the Retirement  Plan which the Executive had accrued  pursuant to the provisions
of such plan as of the date of his death. The benefit payable under this Section
5.6.  shall  commence  and be paid at the same  time and in the same form as the
death benefit, if any, is payable, or would have been payable had Executive been
vested in a death benefit, under the Retirement Plan.

                  6.  Change in Control Severance Payments.

                  6.1 If (i) the Executive's  employment is terminated following
a Change in  Control  and during the Term,  other  than (A) by the  Company  for
Cause,  (B) by reason of death or  Disability,  or (C) by the Executive  without
Good Reason, or (ii) the Executive voluntarily terminates his/her employment for
any reason during the one-month  period  commencing on the first  anniversary of
the Change in  Control,  then,  in either such case,  the Company  shall pay the
Executive the amounts, and provide the Executive the benefits, described in this
Section 6.1 ("Severance  Payments") and Section 6.2, in addition to any payments
and benefits to which the  Executive  is entitled  under  Section 5 hereof.  For
purposes of this Agreement,  the Executive's  employment shall be deemed to have
been terminated following a Change in Control by the Company without Cause or by
the Executive with Good Reason, if (i) the Executive's  employment is terminated
by the  Company  without  Cause  prior to a Change in Control  (whether or not a
Change in Control  thereafter occurs) and such termination was at the request or
direction  of a Person who has entered  into an  agreement  with the Company the
consummation of which would  constitute a Change in Control,  (ii) the Executive
terminates  his/her  employment  for Good  Reason  prior to a Change in  Control
(whether or not a Change in Control  thereafter  occurs) and the circumstance or
event which  constitutes  Good Reason occurs at the request or direction of such
Person, or (iii) the Executive's employment is terminated,  after the occurrence
of a  Potential  Change in  Control  and prior to a Change  in  Control,  by the
Company  without Cause or by the Executive for Good Reason and such  termination
or the  circumstance  or event which  constitutes  Good Reason is  otherwise  in
connection  with or in  anticipation  of a Change in Control which occurs within
six months after the issuance of the Notice of  Termination  in connection  with
such termination.

               (A) In lieu of any further  salary  payments to the Executive for
          periods  subsequent  to the  Date  of  Termination  and in lieu of any
          severance  benefit  otherwise  payable to the  Executive,  the Company
          shall pay to the  Executive  a lump sum  severance  payment,  in cash,
          equal to three times the sum of (i) the Executive's  base salary as in
          effect  immediately prior to the issuance of the Notice of Termination
          in  connection  with  such  termination  or,  if  higher,   in  effect
          (1)immediately prior to the Change in Control or (2) immediately prior
          to the first occurrence of an event or circumstance  constituting Good
          Reason in the event of a  termination  for Good  Reason,  and (ii) the
          average  bonus  earned by the  Executive  pursuant to any annual bonus
          plan and any short term or long term incentive plan  maintained by the
          Company in respect of the three fiscal years or performance periods(or
          such shorter  number of full fiscal  years during which the  Executive
          was employed by the Company)  ending  immediately  prior to the fiscal
          year in which occurs the following,  whichever average is highest: (1)
          the  issuance of the Notice of  Termination  in  connection  with such
          termination; (2) the date of the Change in Control; or (3) the date of
          the first event or circumstance constituting Good Reason.

               (B) For the thirty-six  (36) month period  immediately  following
          the Date of  Termination,  the  Company  shall  arrange to provide the
          Executive and his/her dependents life, disability,  accident,  dental,
          prescription drug and health insurance benefits  substantially similar
          to those provided to the Executive and his/her dependents  immediately
          prior to the issuance of the Notice of Termination in connection  with
          such  termination  or,  if  more  favorable  to the  Executive,  those
          provided to the Executive and his/her dependents  (i)immediately prior
          to the  Change  in  Control  or (ii)  immediately  prior to the  first
          occurrence of an event or circumstance constituting Good Reason in the
          event  of  termination  for Good  Reason,  at no  greater  cost to the
          Executive  than the cost to the  Executive  immediately  prior to such
          date or  occurrence.  Benefits  otherwise  receivable by the Executive
          pursuant  to this  Section  6.1 (B)  shall be  reduced  to the  extent
          benefits  of the same type are  received by or made  available  to the
          Executive at no greater cost during the  thirty-six  (36) month period
          following the  Executive's  termination  of  employment  (and any such
          benefits  received  by or made  available  to the  Executive  shall be
          reported to the Company by the Executive).

               (C) In addition to any retirement benefits to which the Executive
          is  entitled  under each  Pension  Plan  (including  the  supplemental
          pension  benefits  provided  under Sections 5.5 and 5.6 hereof) or any
          successor plan thereto, the Company shall pay the Executive a lump sum
          amount,  in cash, equal to the excess of (i) the actuarial  equivalent
          of the  aggregate  retirement  pension  (taking into account any early
          retirement subsidies associated therewith and determined as a straight
          life annuity  commencing at the date (but in no event earlier than the
          third  anniversary  of  the  Date  of  Termination)  as of  which  the
          actuarial  equivalent of such annuity is greatest) which the Executive
          would  have  accrued  under the terms of all  Pension  Plans  (without
          regard to any  amendment  to any  Pension  Plan made  subsequent  to a
          Change in Control or, if  earlier,  the Notice of  Termination,  which
          amendment   adversely   affects  in  any  manner  the  computation  of
          retirement benefits  thereunder),  determined as if the Executive were
          fully  vested  thereunder,  were thirty six (36) months  older and had
          accumulated (after the Date of Termination) thirty-six (36) additional
          months of service credit  thereunder at an annual rate of compensation
          equal to the annual  salary and average bonus taken into account under
          Section  6.1(A)  hereof,  over (ii) the  actuarial  equivalent  of any
          aggregate  vested  retirement  pension  (taking into account any early
          retirement subsidies associated therewith and determined as a straight
          life annuity  commencing at the date (but in no event earlier than the
          Date of  Termination)  as of which the  actuarial  equivalent  of such
          annuity is greatest)  which the Executive had accrued  pursuant to the
          provisions  of the Pension  Plans as of the Date of  Termination.  For
          purposes  of this  Section  6.1(C),  "actuarial  equivalent"  shall be
          determined  using the same  assumptions  utilized  under the Company's
          tax-qualified  Pension Plan  immediately  prior to the issuance of the
          Notice of Termination in connection with such termination, or, if more
          favorable  to the  Executive,  (i)immediately  prior to the  Change in
          Control or (ii) immediately  prior to the first occurrence of an event
          or circumstance constituting Good Reason in the event of a termination
          for Good Reason.

               (D)  Notwithstanding  any  provision  of any annual or  long-term
          bonus or incentive plan to the contrary,  the Company shall pay to the
          Executive a lump sum amount,  in cash,  equal to the fair market value
          of the sum of (i) any  unpaid  incentive  compensation  which has been
          allocated or awarded to the Executive  for a completed  fiscal year or
          other  measuring  period  preceding the Date of Termination  under any
          such plan and (ii) a pro rata  portion to the Date of  Termination  of
          the aggregate value of all contingent incentive compensation awards to
          the  Executive for all then  uncompleted  periods under any such plan,
          calculated  as to each such  award by  multiplying  the award that the
          Executive would have earned on the last day of the  performance  award
          period,  assuming  the  achievement,  at  the  target  level,  of  the
          individual and corporate performance goals established with respect to
          such award,  by the  fraction  obtained by dividing the number of full
          months and any fractional  portion of a month during such  performance
          award period  through the Date of  Termination  by the total number of
          months contained in such performance award period; provided, that, for
          purposes of any annual  bonus or  incentive  plan,  the award shall be
          calculated  as  if  the  annual  performance  period  had  been  fully
          completed; and further,  provided, that, such incentive awards payable
          under this Section  6.1(D) shall be reduced by the amount,  if any, of
          incentive  awards paid to the  Executive  under any such plan or plans
          for the same performance award periods or any portion thereof.

               (E) The Company  shall provide the  Executive  with  outplacement
          services  suitable to the  Executive's  position for a period expiring
          three years after the Date of Termination,  or, if earlier,  until the
          first acceptance by the Executive of an offer of employment.

                  6.2 (A) Whether or not the Executive  becomes  entitled to the
Severance  Payments,  if any of  the  payments  or  benefits  received  or to be
received  by the  Executive  in  connection  with a  Change  in  Control  or the
Executive's  termination  of employment  (whether  pursuant to the terms of this
Agreement  or any other plan,  arrangement  or agreement  with the Company,  any
Person whose actions result in a Change in Control or any Person affiliated with
the Company or such Person) (such  payments or benefits,  excluding the Gross-Up
Payment,  being hereinafter referred to as the "Total Payments") will be subject
to the Excise Tax, the Company shall pay to the  Executive an additional  amount
(the  "Gross-Up  Payment")  such that the net amount  retained by the Executive,
after  deduction of any Excise Tax on the Total Payments and any federal,  state
and local income and employment taxes and Excise Tax upon the Gross-Up  Payment,
shall be equal to the Total Payments.

               (B) For purposes of determining whether any of the Total Payments
          will be subject to the Excise Tax and the amount of such  Excise  Tax,
          (i) all of the Total Payments shall be treated as "parachute payments"
          (within the meaning of section  280G(b)(2) of the Code) unless, in the
          opinion of tax counsel ("Tax  Counsel")  reasonably  acceptable to the
          Executive and selected by the accounting  firm which was,  immediately
          prior to the Change in Control or, if different,  immediately prior to
          a Potential Change in Control, the Company's  independent auditor (the
          "Auditor"),  such  payments or  benefits  (in whole or in part) do not
          constitute   parachute  payments,   including  by  reason  of  section
          280G(b)(4)(A) of the Code, (ii) all "excess parachute payments" within
          the  meaning  of  section  280G(b)(l)  of the Code shall be treated as
          subject to the Excise Tax unless, in the opinion of Tax Counsel,  such
          excess parachute  payments (in whole or in part) represent  reasonable
          compensation  for services  actually  rendered  (within the meaning of
          section  280G(b)(4)(B)  of the  Code) in  excess  of the  Base  Amount
          allocable  to  such  reasonable  compensation,  or are  otherwise  not
          subject to the Excise Tax, and (iii) the value of any noncash benefits
          or any deferred  payment or benefit shall be determined by the Auditor
          in accordance  with the  principles of sections  280G(d)(3) and (4) of
          the Code.  For  purposes  of  determining  the amount of the  Gross-Up
          Payment,  the Executive  shall be deemed to pay federal  income tax at
          the highest  marginal rate of federal income  taxation in the calendar
          year in which the  Gross-Up  Payment is to be made and state and local
          income taxes at the highest marginal rate of taxation in the state and
          locality of the  Executive's  residence on the Date of Termination (or
          if  there  is no Date of  Termination,  then  the  date on  which  the
          Gross-Up  Payment is calculated for purposes of this Section 6.2), net
          of the  maximum  reduction  in federal  income  taxes  which  could be
          obtained from deduction of such state and local taxes.

               (C) In the event that the Excise  Tax is finally  determined  (as
          hereinafter  defined)  to be less than the amount  taken into  account
          hereunder in calculating  the Gross-Up  Payment,  the Executive  shall
          repay to the Company, within five (5) business days following the time
          that  the  amount  of such  reduction  in the  Excise  Tax is  finally
          determined,  the portion of the Gross-Up Payment  attributable to such
          reduction (plus that portion of the Gross-Up  Payment  attributable to
          the  Excise Tax and  federal,  state and local  income and  employment
          taxes imposed on the Gross-Up  Payment being repaid by the  Executive,
          to the extent that such repayment results in a reduction in the Excise
          Tax  and a  dollar-for-dollar  reduction  in the  Executive's  taxable
          income and wages for  purposes of federal,  state and local income and
          employment  taxes),  plus interest on the amount of such  repayment at
          120% of the rate provided in section 1274(b)(2)(B) of the Code. In the
          event that the Excise Tax is finally  determined  to exceed the amount
          taken into account  hereunder  in  calculating  the  Gross-Up  Payment
          (including  by reason of any payment the  existence or amount of which
          cannot be determined at the time of the Gross-Up Payment), the Company
          shall make an  additional  Gross-Up  Payment in respect of such excess
          (plus any  interest,  penalties or additions  payable by the Executive
          with respect to such excess)  within five (5) business days  following
          the time that the  amount of such  excess is finally  determined.  The
          Executive and the Company  shall each  reasonably  cooperate  with the
          other in connection with any  administrative  or judicial  proceedings
          concerning  the  existence or amount of liability  for Excise Tax with
          respect  to the  Total  Payments.  For  purposes  of  this  Agreement,
          "finally determined" shall mean the earliest to occur of (i) a written
          agreement  between  the  parties  or (ii) a final  judgment,  order or
          decree by an arbitrator or by a court having proper jurisdiction which
          is not subject to appeal or for which the time to appeal has lapsed.

                  6.3 The payments  provided in subsections  (A), (C) and (D) of
Section  6.1 hereof and in Section  6.2 hereof  shall be made not later than the
fifth day  following the Date of  Termination;  provided,  however,  that if the
amounts of such payments cannot be finally determined on or before such day, the
Company  shall pay to the  Executive on such day an estimate,  as  determined in
good  faith by the  Executive  or, in the case of  payments  under  Section  6.2
hereof,  in accordance  with Section 6.2 hereof,  of the minimum  amount of such
payments to which the Executive is clearly  entitled and shall pay the remainder
of such payments (together with interest on the unpaid remainder (or on all such
payments to the extent the Company fails to make such payments when due) at 120%
of the rate provided in section 1274(b)(2)(B) of the Code) as soon as the amount
thereof can be determined  but in no event later than the  thirtieth  (30th) day
after the Date of  Termination.  In the event that the  amount of the  estimated
payments  exceeds  the amount  subsequently  determined  to have been due,  such
excess shall  constitute a loan by the Company to the Executive,  payable on the
fifth (5th) business day after demand by the Company  (together with interest at
120% of the rate  provided in section  1274(b)(2)(B)  of the Code).  At the time
that  payments  are made under this  Agreement,  the Company  shall  provide the
Executive  with a  written  statement  setting  forth the  manner in which  such
payments were calculated and the basis for such calculations including,  without
limitation,  any  opinions or other  advice the Company  has  received  from Tax
Counsel,  the Auditor or other advisors or consultants (and any such opinions or
advice which are in writing shall be attached to the statement).

                  6.4 The Company also shall pay to the Executive all legal fees
and  expenses  incurred by the  Executive  in  disputing in good faith any issue
under this Section 6 relating to the termination of the Executive's  employment,
in seeking in good faith to obtain or enforce any  benefit or right  provided by
this Section 6 or in  connection  with any tax audit or proceeding to the extent
attributable  to the  application  of section 4999 of the Code to any payment or
benefit provided hereunder. Such payments shall be made within five (5) business
days after delivery of the Executive's  written requests for payment accompanied
with such evidence of fees and expenses  incurred as the Company  reasonably may
require.

                  7.  Termination Procedures and Compensation During Dispute.

                  7.1  Notice of  Termination.  During the Term,  any  purported
termination of the Executive's  employment (other than by reason of death) shall
be  communicated  by written Notice of Termination  from one party hereto to the
other party hereto in  accordance  with Section 10 hereof.  For purposes of this
Agreement,  a "Notice of  Termination"  shall mean a notice which shall indicate
the specific  termination  provision in this Agreement relied upon and shall set
forth in  reasonable  detail  the facts and  circumstances  claimed to provide a
basis for  termination  of the  Executive's  employment  under the  provision so
indicated.  Further,  a Notice of Termination for Cause is required to include a
copy of a  resolution  duly  adopted  by the  affirmative  vote of not less than
three-quarters  (3/4) of the entire  membership of the Board at a meeting of the
Board which was called and held for the purpose of considering  such termination
(after  reasonable notice to the Executive and an opportunity for the Executive,
together with the  Executive's  counsel,  to be heard before the Board)  finding
that,  in the good  faith  opinion  of the Board,  the  Executive  was guilty of
conduct set forth in clause (i) or (ii) of the  definition of Cause herein,  and
specifying the particulars thereof in detail.

                  7.2 Date of Termination.  "Date of Termination,"  with respect
to any purported  termination  of the  Executive's  employment  during the Term,
shall mean (i) if the  Executive's  employment  is  terminated  for  Disability,
thirty  (30)  days  after  Notice of  Termination  is given  (provided  that the
Executive  shall  not  have  returned  to  the  full-time   performance  of  the
Executive's  duties  during  such  thirty  (30)  day  period),  and  (ii) if the
Executive's employment is terminated for any other reason, the date specified in
the Notice of Termination  (which,  in the case of a termination by the Company,
shall not be less than thirty (30) days (except in the case of a termination for
Cause) nor more than sixty (60) days and,  in the case of a  termination  by the
Executive,  shall not be less than  fifteen  (15) days nor more than  sixty (60)
days, respectively, from the date such Notice of Termination is given).

                  7.3 Dispute  Concerning  Termination.  If within  fifteen (15)
days after any Notice of Termination is given,  or, if later,  prior to the Date
of  Termination  (as  determined  without regard to this Section 7.3), the party
receiving  such Notice of  Termination  notifies  the other party that a dispute
exists  concerning  the  payment  of  amounts  set  forth in  Section  6 of this
Agreement,  the Date of  Termination  shall be extended until the earlier of (i)
the date on which the Term ends or (ii) the date on which the dispute is finally
resolved,  either by  mutual  written  agreement  of the  parties  or by a final
judgment, order or decree of an arbitrator;  provided, however, that the Date of
Termination shall be extended by a notice of dispute given by the Executive only
if such notice is given in good faith and the Executive  pursues the  resolution
of such dispute with reasonable diligence.

                  7.4 Compensation  During Dispute.  If a purported  termination
occurs  during the Term and the Date of  Termination  is extended in  accordance
with Section 7.3 hereof,  the Company  shall  continue to pay the  Executive the
full compensation in effect when the notice giving rise to the dispute was given
(including,  but not  limited  to,  salary)  and  continue  the  Executive  as a
participant  in all  compensation,  benefit  and  insurance  plans in which  the
Executive  was  participating  when the notice  giving  rise to the  dispute was
given,  until the Date of Termination,  as determined in accordance with Section
7.3  hereof.  Amounts  paid under this  Section 7.4 are in addition to all other
amounts due under this Agreement (other than those due under Section 5.2 hereof)
and shall not be offset  against  or reduce  any other  amounts  due under  this
Agreement.

                  8. No Mitigation.  The Company agrees that, if the Executive's
employment  with the Company  terminates  during the Term,  the Executive is not
required to seek other employment or to attempt in any way to reduce any amounts
payable to the  Executive  by the Company  pursuant  to  Sections  5.4, 6 or 7.4
hereof.  Further,  if the Date of  Termination  occurs  following  a  Change  in
Control,  the amount of any payment or benefit  provided  for in this  Agreement
(other than  Section  6.1(B)  hereof)  shall not be reduced by any  compensation
earned by the  Executive as the result of  employment  by another  employer,  by
retirement  benefits,  by offset  against  any amount  claimed to be owed by the
Executive to the Company, or otherwise.

                  9.  Successors; Binding Agreement.

                  9.1 In  addition  to any  obligations  imposed by law upon any
successor to the Company, the Company will require any successor (whether direct
or  indirect,  by  purchase,  merger,  consolidation  or  otherwise)  to  all or
substantially  all of the  business  and/or  assets of the Company to  expressly
assume and agree to perform  this  Agreement  in the same manner and to the same
extent  that the Company  would be required to perform it if no such  succession
had taken place.  Failure of the Company to obtain such assumption and agreement
prior to the  effectiveness of any such succession which is in connection with a
Change in Control  shall be a breach of this  Agreement  and shall  entitle  the
Executive  to  compensation  from the Company in the same amount and on the same
terms as the Executive  would be entitled to hereunder if the Executive  were to
terminate the Executive's  employment for Good Reason after a Change in Control,
except that, for purposes of implementing  the foregoing,  the date on which any
such succession becomes effective shall be deemed the Date of Termination.

                  9.2  This  Agreement  shall  inure  to the  benefit  of and be
enforceable by the  Executive's  personal or legal  representatives,  executors,
administrators,  successors, heirs, distributees,  devisees and legatees. If the
Executive  shall die while any amount  would  still be payable to the  Executive
hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts,  unless
otherwise  provided  herein,  shall be paid in accordance with the terms of this
Agreement to the executors,  personal  representatives  or administrators of the
Executive's estate.

                  10. Notices.  For the purpose of this  Agreement,  notices and
all other  communications  provided for in the Agreement shall be in writing and
shall be  deemed  to have been duly  given  when  delivered  or mailed by United
States registered mail, return receipt requested, postage prepaid, addressed, if
to the Executive, to the address inserted below the Executive's signature on the
final page hereof and, if to the Company,  to the address set forth below, or to
such other address as either party may have furnished to the other in writing in
accordance herewith,  except that notice of change of address shall be effective
only upon actual receipt:

                           Attention:  Corporate Secretary

                  11.  Miscellaneous.  No  provision  of this  Agreement  may be
modified, waived or discharged unless such waiver,  modification or discharge is
agreed to in writing  and  signed by the  Executive  and such  officer as may be
specifically  designated  by the Board.  No waiver by either party hereto at any
time of any breach by the other  party  hereto of, or of any lack of  compliance
with, any condition or provision of this Agreement to be performed by such other
party shall be deemed a waiver of similar or dissimilar provisions or conditions
at the same or at any prior or subsequent  time.  This Agreement  supersedes any
other agreements or representations, oral or otherwise, express or implied, with
respect to the subject  matter hereof which have been made by either party.  The
validity,  interpretation,  construction and performance of this Agreement shall
be governed by the laws of the State of Connecticut.  All references to sections
of the Exchange  Act or the Code shall be deemed also to refer to any  successor
provisions to such sections.  Any payments  provided for hereunder shall be paid
net of any applicable withholding required under federal, state or local law and
any additional withholding to which the Executive has agreed. The obligations of
the Company and the  Executive  under this  Agreement  which by their nature may
require  either  partial or total  performance  after the expiration of the Term
(including,  without  limitation,  those under  Sections  5.4, 5.5, 5.6, 6 and 7
hereof) shall survive such expiration.

                  12.  Validity.  The  invalidity  or  unenforceability  of  any
provision of this Agreement shall not affect the validity or  enforceability  of
any other  provision  of this  Agreement,  which shall  remain in full force and
effect.

                  13.  Counterparts.  This  Agreement may be executed in several
counterparts,  each of which shall be deemed to be an original  but all of which
together will constitute one and the same instrument.

                  14.  Settlement of Disputes; Arbitration.

                  14.1 All claims by the Executive for  compensation or benefits
under this Agreement  (other than claims for compensation or benefits payable in
connection  with a Change in Control) shall be directed to and determined by the
Board  and  shall be in  writing.  Any  denial  by the Board of such a claim for
compensation  or benefits  shall be  delivered  to the  Executive in writing and
shall set forth the specific reasons for the denial and the specific  provisions
of this Agreement  relied upon. The Board shall afford a reasonable  opportunity
to the  Executive  for a review of the  decision  denying such a claim and shall
further  allow the  Executive  to appeal  to the Board a  decision  of the Board
within  sixty (60) days  after  notification  by the Board that the  Executive's
claim has been denied.

                  14.2 Any dispute or  controversy  arising under this Agreement
in connection with any termination-related  compensation or benefit and any such
dispute or controversy in connection  with a claim for  compensation or benefits
to which  Section 14.1 applies  (after  application  of the  provisions  of said
Section  14.1)  shall  be  settled   exclusively  by  arbitration  in  Hartford,
Connecticut in accordance with the rules of the American Arbitration Association
then in effect.  Judgment may be entered on the arbitrator's  award in any court
having  jurisdiction.  Notwithstanding  any  provision of this  Agreement to the
contrary,  the Executive  shall be entitled to seek specific  performance in any
court having proper  jurisdiction of the Executive's  right to be paid until the
Date of Termination  during the pendency of any dispute or  controversy  arising
under or in connection with this Agreement.

such failure resulting from the Executive's incapacity due to physical or mental

of Termination for Good Reason by the Executive  pursuant to Section 7.1 hereof)
after a written demand for substantial performance is delivered to the Executive
by the Board,  which demand  specifically  (a)identifies the manner in which the
Board  believes  that  the  Executive  has  not   substantially   performed  the
Executive's  duties and (b) states a period of time within  which the  Executive
must  correct  such  failure   (which  is  reasonable   based  on  the  specific

in the best interest of the Company.

                  voting power of the  Company's  then  outstanding  securities,
                  excluding  any Person who becomes such a  Beneficial  Owner in

                  consent solicitation, relating to the election of directors of

                  ownership of the Company immediately prior to such sale.

Notwithstanding the foregoing, a "Change in Control" shall not be deemed to have
occurred  by  virtue  of  the  consummation  of any  transaction  or  series  of
integrated  transactions  immediately  following which the record holders of the
common stock of the Company  immediately  prior to such transaction or series of

                  alteration  in  the  nature  or  status  of  the   Executive's

                  in  effect  any  compensation  plan  in  which  the  Executive
                  participates  immediately prior to the Change in Control which
                  is material to the Executive's total  compensation,  unless an
                  equitable  arrangement  (embodied in an ongoing  substitute or
                  alternative  plan) has been made with respect to such plan, or

                  plan) on a basis not materially less favorable,  both in terms
                  of the amount or timing of payment of  benefits  provided  and
                  the level of the Executive's  participation  relative to other

                  Control;

                                    (VI) the  failure by the Company to continue
                  to provide the Executive with benefits  substantially  similar
                  to those enjoyed by the  Executive  under any of the Company's
                  pension,   savings,  life  insurance,   medical,   health  and

          Option  Plan  which  are  forfeited,  expire or are  canceled  without
          delivery  of shares  of Stock or which  result  in the  forfeiture  of
          shares of Stock back to the  Company.  Preferred  Stock may be used in
          lieu  of  grants  of  Stock   under  the  Plan   subject   to  further

          foregoing,  in no event  shall the  Committee  grant  any  Participant
          Incentive  Stock Options,  Nonstatutory  Options,  Nonstatutory  Stock
          Options,  Stock Appreciation  Rights or Restricted Stock in any single

          the  Company  because of the failure to meet an award  contingency  or
          condition shall again be available for delivery pursuant to new awards
          granted  under the Plan.  To the extent any shares of Stock covered by
          an award  are not  delivered  to a  Participant  because  the award is
          forfeited,  canceled  or  expired,  or the  shares  are not  delivered
          because the award is settled in cash or used to satisfy the applicable
          tax  withholding  obligation,  such shares shall not be deemed to have
          been  delivered  for  purposes of  determining  the maximum  number of
          shares of Stock  available  for  delivery  under the Plan.

     (c)  If the exercise  price of any stock option  granted  under the Plan or
          the Company's 1985 Stock Option Plan is satisfied by tendering  shares
          of Stock to the Company (by either actual delivery or by attestation),
          only the  number of shares of Stock  issued net of the shares of Stock
          tendered  shall be deemed  delivered for purposes of  determining  the
          maximum  number of shares of Stock  available  for delivery  under the
          Plan.

     (d)  Upon the  exercise  of an option  or a Stock  Appreciation  Right,  or
          payment of a Restricted  Stock award, the Company may distribute newly
          issued  shares  or  shares  previously  repurchased  on  behalf of the
          Company through a broker or other  independent agent designated by the
          Committee.  Such  repurchases  shall  be  subject  to such  rules  and
          procedures  as the  Committee  may  establish  hereunder  and shall be
          consistent with such conditions as may be prescribed from time to time
          by law or by the  Securities  and Exchange  Commission  ("SEC") in any
          rule or  regulation  or in any  exemptive  order or  no-action  letter
          issued by the SEC to the  Company  or the broker  with  respect to the
          making of such purchase or otherwise.

     with  respect  to  which  ISOs are  exercisable  for the  first  time by an
     individual  during any calendar  year (under this Plan and any other option
     plan of the Company) shall not exceed $100,000.  No such maximum limitation
     shall apply to Nonstatutory Stock Options.


2.2  Terms and Conditions of Options

     Each option granted under the Plan shall be authorized by the Committee and
     shall be evidenced by an instrument delivered to the Participant, in a form
     approved by the Committee,  containing  the following  terms and conditions
     and such other terms and conditions as the Committee may deem appropriate.

     (a)  Option Term - Each option shall  specify the term for which the option
          thereunder  is granted and shall  provide that the option shall expire
          at the end of such term.  In no event shall any option be  exercisable
          any earlier than one year after the date of such grant.  The Committee
          shall have  authority to grant  options  exercisable  in cumulative or
          non-cumulative installments.  No option shall be exercisable after the
          expiration  of ten  years  from the date  upon  which  such  option is
          granted. Notwithstanding anything to the contrary contained herein, in
          the  event of a Change  in  Control,  all  outstanding  options  shall
          immediately become exercisable.

     (b)  Option Price - The option price per share shall be  determined  by the
          Committee at the time an option is granted, and shall not be less than
          the Fair Market  Value of one share of Stock on the date the option is
          granted.

     (c)  Exercise of Option -

          (1)  Options may be  exercised  only by proper  written  notice to the
               Company or its duly  authorized  agent  accompanied by the proper
               amount of payment  for the  shares,  as  provided  under  Section
               2.2(d) hereunder.

          (2)  The  Committee  may postpone any exercise of an option or a Stock
               Appreciation  Right or the delivery of Stock  following the lapse
               of certain  restrictions  with  respect  to awards of  Restricted
               Stock for such time as the Committee in its  discretion  may deem
               necessary,  in  order  to  permit  the  Company  with  reasonable
               diligence (i) to effect or maintain  registration  of the Plan or
               the shares  issuable upon the exercise of the option or the Stock
               Appreciation   Right  or  the  lapse  of   certain   restrictions
               respecting awards of Restricted Stock under the Securities Act of
               1933,  as  amended,  or the  securities  laws  of any  applicable
               jurisdiction,  or (ii) to determine that such shares and Plan are
               exempt from such registration; the Company shall not be obligated
               by virtue of any option or any provision of the Plan to recognize
               the exercise of an option or the exercise of a Stock Appreciation
               Right or the lapse of certain  restrictions  respecting awards of
               Restricted Stock to sell or issue shares in violation of said Act
               or of the law of the government having jurisdiction  thereof. Any
               such postponement shall not extend the term of an option; neither
               the  Company  nor  its  directors  or  officers  shall  have  any
               obligation  or  liability  to the  Optionee of an option or Stock
               Appreciation Right, or to the Optionee's Beneficiary with respect
               to any shares as to which the option or Stock  Appreciation Right
               shall lapse because of such postponement.

          (3)  To the extent an option is not  exercised for the total number of
               shares with respect to which such options become exercisable, the
               number of  unexercised  shares  shall  accumulate  and the option
               shall be exercisable, to such extent, at any time thereafter, but
               in no event  later  than ten years  from the date the  option was
               granted or after the  expiration of such shorter  period (if any)
               which the  Committee  may have  established  with respect to such
               option pursuant to Subsection (a) of this Section 2.2.

     (d)  Payment of Purchase Upon Exercise - Payment for the shares as to which
          an option is exercised shall be made in one of the following ways:

          (1)  payment in cash or if  permitted by the  Committee,  by tendering
               shares of Stock of the  Company  (by either  actual  delivery  of
               shares or by attestation,  with such shares valued at Fair Market
               Value as of the day of  exercise)  held by the  purchaser  for at
               least six months; or in any combination thereof, as determined by
               the Committee; or

          (2)  if  permitted  by the  Committee,  a  Participant  may  elect  to
               authorize a third party to sell shares of Stock (or a  sufficient
               portion of the shares)  acquired  upon exercise of the option and
               remit to the Company a sufficient  portion of the sales  proceeds
               to  pay  the  entire  exercise  price  and  any  tax  withholding
               resulting from such exercise.

     (e)  Nontransferability  - No  option  granted  under  the  Plan  shall  be
          transferable  other  than  by  will  or by the  laws  of  descent  and
          distribution  subject to Section 2.4  hereunder,  unless the Committee
          shall permit (on such terms and conditions as it shall establish) such
          option to be  transferred to a member of the  Participant's  immediate
          family  or to a trust  or  similar  vehicle  for the  benefit  of such
          immediate family members, or to an "alternate participant" pursuant to
          a Qualified  Domestic  Relations Order as defined in the Code.  During
          the lifetime of an Optionee,  an option shall be  exercisable  only by
          such Optionee, or if applicable, a transferee. For purposes of Section
          2.4 hereunder, a transferred option may be exercised by the transferee
          to the extent that the  Participant  would have been  entitled had the
          option not been transferred.

     (f)  Laws and Regulations - The Committee shall have the right to condition
          any issuance of shares to any Optionee or  Participant  hereunder upon
          such Optionee's or Participant's undertaking in writing to comply with
          such restrictions on the subsequent  disposition of such shares as the
          Committee  shall  deem  necessary  or  advisable  as a  result  of any
          applicable law or regulation. In the case of Stock issued or cash paid
          upon exercise of options or associated Stock  Appreciation  Rights, or
          the lapse of restrictions  with respect to Restricted Stock awarded to
          a  Participant  under the Plan,  the  Optionee,  Participant  or other
          person  receiving  such Stock or cash shall be  required to pay to the
          Company or Related  Company  the amount of any taxes which the Company
          or Related  Company is required to withhold with respect to such Stock
          or cash. The Company or Related  Company may, in its sole  discretion,
          permit an Optionee or Participant or other person receiving such Stock
          or  cash  to  satisfy  any  Federal,  state  or  local  (if  any)  tax
          withholding requirements, in whole or in part by (i) delivering to the
          Company or  Related  Company  shares of Stock  held by such  Optionee,
          Participant  or other  person  having a Fair Market Value equal to the
          amount of the tax or (ii) directing the Company or Related  Company to
          retain Stock otherwise issuable to the Optionee,  Participant or other
          person  under the Plan having a Fair Market  Value equal to the amount
          of the tax.  If Stock is used to satisfy tax  withholding,  such Stock
          shall  be  valued  based  on  the  Fair  Market  Value  when  the  tax
          withholding is required to be made.

     (g)  Modification - The Committee  shall have authority to modify an option
          without the consent of the Optionee,  provided that such  modification
          does not affect the exercise  price or otherwise  materially  diminish
          the value of such option to the Optionee,  and provided further,  that
          except in  connection  with an  amendment to the Plan,  the  Committee
          shall not have  authority to make any  modification  to any particular
          option  that  materially  increases  the  value of the  option  to the
          Optionee.

2.3  Stock Appreciation Rights

     (a)  The  Committee  may,  but  shall  not be  required  to,  grant a Stock
          Appreciation  Right to the  Optionee  either  at the time an option is
          granted or by amending  the option at any time during the term of such
          option.  A Stock  Appreciation  Right shall be exercisable only during
          the  term  of the  option  with  which  it is  associated.  The  Stock
          Appreciation  Right shall be an integral part of the option with which
          it is  associated  and shall have no existence  apart  therefrom.  The
          conditions and  limitations of the Stock  Appreciation  Right shall be
          determined  by the  Committee  and shall be set forth in the option or
          amendment  thereto.  An amendment  granting a Stock Appreciation Right
          shall not be deemed to be a grant of a new option for  purposes of the
          Plan.

     (b)  A Stock Appreciation Right may be exercised by:

          (1)  filing  with the  Secretary  of the  Company a written  election,
               which  election  shall  be  delivered  by  the  Secretary  to the
               Committee specifying:

               (i) the option or portion thereof to be surrendered; and

               (ii)  the  percentage  of the  Appreciation  which  the  Optionee
          desires to receive in cash, if any; and

          (2)  surrendering    such   option   for   cancellation   or   partial
               cancellation,  as the case may be,  provided,  however,  that any
               election to receive any portion of the Appreciation in cash shall
               be of no force or effect  unless  and until the  Committee  shall
               have consented to such election.

     (c)  No election to receive any portion of the  Appreciation  in cash shall
          be filed with the Secretary and no Stock  Appreciation  Right shall be
          exercised to receive any cash unless such election and exercise  shall
          occur during the period  (hereinafter  referred to as the "Cash Window
          Period")  beginning on the third  business day  following  the date of
          release  for  publication  by the  Company of a regular  quarterly  or
          annual  statement  of sales and  earnings  and  ending on the  twelfth
          business day  following  such date.  The  Committee may consent to the
          election  of a holder to receive any  portion of the  Appreciation  in
          cash at any time after such  election has been made.  If such election
          is consented to, the Stock  Appreciation Right shall be deemed to have
          been  exercised  during  the Cash  Window  Period  in  which,  or next
          occurring  after which,  the Optionee  completed  all acts required of
          such  Optionee  under the  preceding  paragraphs to exercise the Stock
          Appreciation Right. Any Stock Appreciation Right exercised during said
          Cash Window Period shall be valued and deemed exercised as of the date
          during  such Cash  Window  Period when the average of the high and low
          prices for the shares of Stock as reported by the NYSE is the highest.

2.4  Exercise of Option or Stock  Appreciation Right in the Event of Termination
     of Employment or Death

     (a)  Options and  associated  Stock  Appreciation  Rights  shall  terminate
          immediately  upon the  termination  of the  Optionee's  employment (or
          cessation of the provision of services)  with the Company or a Related
          Company unless the written option instrument of such Optionee provides
          otherwise.   The  conditions  established  by  the  Committee  in  the
          instrument  for  exercising  options  and  Stock  Appreciation  Rights
          following  termination of employment (or cessation of the provision of
          services) are limited by the following restrictions.

          (1)  If  termination  of employment  (or cessation of the provision of
               services) is by reason of the death of the Optionee,  no exercise
               by the Optionee's Beneficiary may occur more than two years after
               the Optionee's death.

          (2)  If  termination  of employment  (or cessation of the provision of
               services) is the result of Disability or Retirement,  no exercise
               by the Optionee or his  Beneficiary may occur more than two years
               following  such  termination  of employment  (or cessation of the
               provision of services).

          (3)  If  termination  of employment  (or cessation of the provision of
               services)  is  for  a  reason   other  than  death,   Disability,
               Retirement or "involuntary termination for cause", no exercise by
               the  Optionee  may occur more than three  months  following  such
               termination  of  employment  (or  cessation  of the  provision of
               services).  As used herein  "involuntary  termination  for cause"
               shall  mean  termination  of  employment  (or  cessation  of  the
               provision of services) by reason of the Optionee's  commission of
               a felony,  fraud or willful misconduct which has resulted,  or is
               likely to  result,  in  substantial  and  material  damage to the
               Company or a Related Company.  Whether an involuntary termination
               is for "cause" will be determined  in the sole  discretion of the
               Committee.

     (b)  If the  Optionee  should  die  after  termination  of  employment  (or
          cessation of provision of services), such termination (or cessation of
          provision  of  services)  being for a reason  other  than  Disability,
          Retirement or involuntary  termination for cause, but while the option
          is still  exercisable,  the option or  associated  Stock  Appreciation
          Right,  if any, may be exercised by the Beneficiary of the Optionee no
          later than one year from the date of  termination  of  employment  (or
          cessation of provision of services) of the Optionee.

     (c)  Under no circumstances  may an option or Stock  Appreciation  Right be
          exercised by an Optionee or  Beneficiary  after the  expiration of the
          term specified for the option.

2.5  Awarding of Restricted Stock

     (a)  The  Committee  shall  from  time to time in its  absolute  discretion
          select the  Participants  to whom awards of Restricted  Stock shall be
          granted and the number of shares subject to such awards. Each award of
          Restricted  Stock under the Plan shall be evidenced  by an  instrument
          delivered  to the  Participant  in such  form as the  Committee  shall
          prescribe  from  time  to  time  in  accordance  with  the  Plan.  The
          Restricted Stock subject to such award shall be registered in the name
          of the  Participant  and held in escrow by the  Committee  during  the
          Restricted Period (as defined herein).

     (b)  Upon the award to a Participant of shares of Restricted Stock pursuant
          to Section 2.5(a), the Participant shall, subject to Subsection (c) of
          this Section 2.5,  possess all  incidents of ownership of such shares,
          including the right to receive  dividends  with respect to such shares
          and to vote such shares.

     (c)  Shares of Restricted  Stock awarded to a Participant  may not be sold,
          assigned, transferred, pledged, hypothecated or otherwise disposed of,
          except by will or the laws of descent and  distribution,  for a period
          of  five  years,  or  such  shorter  period  as  the  Committee  shall
          determine,   from  the  date  on  which  the  award  is  granted  (the
          "Restricted  Period").  The  Committee  may  also  impose  such  other
          restrictions and conditions on the shares as it deems  appropriate and
          any  attempt  to  dispose of any such  shares of  Restricted  Stock in
          contravention of such restrictions  shall be null and void and without
          effect.  In  determining  the  Restricted  Period  of  an  award,  the
          Committee may provide that the foregoing restrictions shall lapse with
          respect to specified  percentages  of the awarded shares on successive
          anniversaries  of the  date of  such  award.  In no  event  shall  the
          Restricted  Period end with  respect to  awarded  shares  prior to the
          satisfaction by the Participant of any liability arising under Section
          2.2(f).

     (d)  The  restrictions  described  in Section  2.5(c)  shall lapse upon the
          completion of the Restricted Period with respect to specific shares of
          Restricted Stock and the Participant's right to such shares shall vest
          on  such  date  or,  if  earlier,  on the  date  of the  Participant's
          termination  of employment (or cessation of the provision of services)
          on account of the death,  Disability or Retirement of the Participant.
          The Company shall deliver to the  Participant,  or the  Beneficiary of
          such Participant, if applicable,  within 30 days of the termination of
          the Restricted Period, the number of shares of Stock that were awarded
          to the  Participant as Restricted  Stock and with respect to which the
          restrictions  imposed under Section 2.5(c) have lapsed, less any stock
          returned by the Company to satisfy tax withholding pursuant to Section
          2.2(f), if applicable.

     (e)  Except as provided in  Sections  2.5(d) and (f), if the  Participant's
          continuous  employment  (or  other  provision  of  services)  with the
          Company or a Related  Employer shall terminate for any reason prior to
          the  expiration  of the  Restricted  Period  of an award,  any  shares
          remaining subject to restrictions  shall thereupon be forfeited by the
          Participant  and  transferred to, and reacquired by, the Company at no
          cost to the Company.

     (f)  The Committee shall have the authority (and the instrument  evidencing
          an award of  Restricted  Stock may so  provide)  to cancel  all or any
          portion of any outstanding restrictions prior to the expiration of the
          Restricted  Period  with  respect  to any or  all  of  the  shares  of
          Restricted Stock awarded to a Participant  hereunder on such terms and
          conditions as the Committee may deem appropriate.

     (g)  In  the  event  of a  Change  in  Control,  all  restrictions  on  any
          outstanding  shares of Restricted  Stock shall lapse as of the date of
          such Change in Control.

ARTICLE III - GENERAL PROVISIONS

3.1  Authority

     Appropriate  officers  of  the  Company  designated  by the  Committee  are
     authorized to execute and deliver  written  instruments  evidencing  awards
     hereunder,  and amendments thereto, in the name of the Company, as directed
     from time to time by the Committee.

3.2  Adjustments in the Event of Change in Common Stock of the Company

     In the event of any  change in the  Stock of the  Company  by reason of any
     stock  dividend,  stock split,  recapitalization,  reorganization,  merger,
     consolidation,  split-up,  combination,  or exchange  of shares,  or rights
     offering  to  purchase  Stock at a price  substantially  below Fair  Market
     Value, or of any similar change affecting the Stock, the number and kind of
     shares  which  thereafter  may be obtained  and sold under the Plan and the
     number  and  kind of  shares  subject  to  options  in  outstanding  option
     instruments  and the  purchase  price per share  thereof  and the number of
     shares of Restricted  Stock awarded pursuant to Section 2.5(a) with respect
     to which all restrictions have not lapsed, shall be appropriately  adjusted
     consistent  with such change in such manner as the Board in its  discretion
     may deem  equitable to prevent  substantial  dilution or enlargement of the
     rights  granted  to,  or  available  for,  Participants  in the  Plan.  Any
     fractional  shares  resulting  from such  adjustments  shall be eliminated.
     However,  without the consent of the Optionee,  no adjustment shall be made
     in the terms of an ISO  which  would  disqualify  it from  treatment  under
     Section 421(a) of the Code or would be considered a modification, extension
     or renewal of an option under Section 425(h) of the Code.

3.3  Rights of Participants

     The Plan and any  option or award  granted  under the Plan shall not confer
     upon any Optionee or  Participant  any right with respect to continuance of
     employment  (or other  provision of services) by the Company or any Related
     Employer nor shall they  interfere in any way with the right of the Company
     or Related  Employer  by which an Optionee  or  Participant  is employed to
     terminate his employment (or other  provision of services) at any time. The
     Company  shall not be obligated to issue Stock  pursuant to an option or an
     award of Restricted Stock for which the restrictions  hereunder have lapsed
     if such issuance  would  constitute a violation of any  applicable  law. No
     Optionee shall have any rights as a shareholder  with respect to any shares
     subject  to option  prior to the date of  issuance  to such  Optionee  of a
     certificate or certificates for such shares.  Except as provided herein, no
     Participant  shall have any  rights as a  shareholder  with  respect to any
     shares of Restricted Stock awarded to such Participant.

3.4  Amendment, Suspension and Discontinuance of the Plan

     The Board may from time to time  amend,  suspend or  discontinue  the Plan,
     provided that the Board may not, without shareholder approval,  take any of
     the  following  actions  unless such actions fall within the  provisions of
     Section 3.2 herein:

     (a)  increase the number of shares reserved for options pursuant to Section
          1.5;

     (b)  alter in any way the class of persons  eligible to  participate in the
          Plan;

     (c)  permit the  granting  of any option at an option  price less than that
          provided under Section 2.2(b) hereof; or

     (d)  extend the term of the Plan or the term during which any option may be

     THIS  AGREEMENT,  made and  entered  into this 29th day of  November,  1999
between  HSB  Group,  Inc.  (hereinafter  referred  to  as  the  "Company"),   a
corporation  organized and existing  under the laws of the State of  Connecticut

     WHEREAS,  the Company  considers it essential to the best  interests of its
shareholders to attract and retain key executives; and

     WHEREAS, the Executive is willing to join the Company as a key executive if
the  Company  will  agree  to pay  him  or his  designees  certain  benefits  in
accordance with the provisions and conditions hereinafter set forth;

     NOW,  THEREFORE,  for value  received  and in  consideration  of the mutual
covenants contained herein, the parties covenant and agree as follows:

     mean  (i)  the  willful  and   continued   failure  by  the   Executive  to
     substantially  perform the Executive's  duties with the Company (other than
     any such failure resulting from the Executive's  incapacity due to physical
     or mental  illness  or any such  actual or  anticipated  failure  after the
     issuance  of a Notice  of  Termination  for Good  Reason  by the  Executive
     pursuant  to Section  6.1 hereof)  after a written  demand for  substantial
     performance  is  delivered  to the  Executive  by the Board,  which  demand
     specifically (a) identifies the manner in which the Board believes that the
     Executive has not  substantially  performed the Executive's  duties and (b)
     states a period  of time  within  which the  Executive  must  correct  such
     failure (which is reasonable  based on the specific  circumstances  of such

     directors on the date hereof or whose  appointment,  election or nomination
     for election was previously so approved or recommended; or

          (c) there is consummated a merger or  consolidation  of the Company or
     any  direct  or  indirect   subsidiary   of  the  Company  with  any  other
     corporation, other than (i) a merger or consolidation which would result in
     the voting securities of the Company outstanding  immediately prior to such
     merger or  consolidation  continuing  to  represent  (either  by  remaining
     outstanding or by being  converted into voting  securities of the surviving
     entity or any parent  thereof),  in  combination  with the ownership of any
     trustee or other fiduciary  holding  securities  under an employee  benefit
     plan of the Company or any  subsidiary of the Company,  at least 60% of the
     combined  voting power of the  securities of the Company or such  surviving
     entity or any parent thereof  outstanding  immediately after such merger or
     consolidation,  or (ii) a merger or  consolidation  effected to implement a

     Person any securities acquired directly from the Company or its Affiliates)
     representing 25% or more of the combined voting power of the Company's then
     outstanding securities; or

          (d)  the  shareholders  of the  Company  approve  a plan  of  complete

     entity,  at least 60% of the combined voting power of the voting securities
     of which are owned by shareholders of the Company in substantially the same
     proportions  as their  ownership of the Company  immediately  prior to such
     sale.

     Notwithstanding the foregoing, a "Change in Control" shall not be deemed to
     have occurred by virtue of the consummation of any transaction or series of
     integrated  transactions  immediately following which the record holders of
     the common stock of the Company  immediately  prior to such  transaction or
     series  of   transactions   continue   to  have   substantially   the  same

     of transactions.

1.8  "Disability"  shall be deemed the reason for the  Termination of Employment
     of  the  Executive  by the  Company  if,  as a  result  of the  Executive's

     circumstance  constituting  Good Reason in the event of a  termination  for
     Good Reason.

1.12 "Good Reason" for Termination of Employment by the Executive shall mean the
     occurrence  (without the  Executive's  express  written  consent) after any

     a "Change in Control" as references to a "Potential Change in Control"), of
     any one of the following acts by the Company, or failures by the Company to
     act,  unless,  in the  case  of any  act or  failure  to act  described  in
     paragraph  (a),  (e),  (f) or (g)  below,  such  act or  failure  to act is
     corrected  prior to the date of  termination  specified  in the  Notice  of
     Termination given in respect thereof:

          (a) the  assignment to the Executive of any duties  inconsistent  with

     business to an extent substantially consistent with the Executive's present
     business travel obligations;

          (d) the failure by the Company to pay to the  Executive any portion of
     the Executive's current compensation except pursuant to an across-the-board

     plan)  has been made with  respect  to such  plan,  or the  failure  by the
     Company to  continue  the  Executive's  participation  therein  (or in such
     substitute or alternative  plan) on a basis not materially  less favorable,
     both in terms of the amount or timing of payment of benefits  provided  and

     in Control, or the failure by the Company to provide the Executive with the
     number of paid  vacation  days to which the  Executive  is  entitled on the
     basis of years of service with the Company in accordance with the Company's
     normal vacation policy in effect at the time of the Change in Control; or

     not  effected   pursuant  to  a  Notice  of   Termination   satisfying  the
     requirements of Section 6.1 hereof; for purposes of this Agreement, no such
     purported termination shall be effective.

     The  Executive's  right to terminate the  Executive's  employment  for Good
     Reason shall not be affected by the Executive's  incapacity due to physical
     or  mental  illness.   The  Executive's   continued  employment  shall  not
     constitute  consent to, or a waiver of rights  with  respect to, any act or
     failure to act constituting Good Reason hereunder.

     hereof.

     the Company in  substantially  the same  proportions as their  ownership of
     stock of the Company.

1.15     "Potential  Change in Control"  shall be deemed to have occurred if the
         event  set  forth in any one of the  following  paragraphs  shall  have
         occurred:

          (a) the Company enters into an agreement,  the  consummation  of which
     would result in the occurrence of a Change in Control;

          (b) the Company or any Person publicly  announces an intention to take
     or to consider  taking actions which, if  consummated,  would  constitute a

     of  securities of the Company  representing  10% or more of either the then
     outstanding  shares of common stock of the Company or the  combined  voting
     power of the Company's then  outstanding  securities  (not including in the

     death,  Disability  or Good  Reason  following  a Change in  Control of the
     Executive  pursuant to the provisions of Article IV) hereof,  the Executive

     to receive  payments on account of Disability,  the condition of Disability
     no longer exists, the Company's  obligation to make any further payments on
     account  of such  Disability  will  terminate  on the  date on  which  such
     Disability no longer exists.


 ARTICLE IV - TERMINATION OF EXECUTIVE'S EMPLOYMENT FOLLOWING CHANGE IN CONTROL

4.1  In lieu of the benefit,  if any, to which the  Executive  would be entitled
     under  the  provisions  of  Article  III  hereof,  if  (i)  Termination  of

     termination  was at the  request or  direction  of a Person who has entered
     into an  agreement  with  the  Company  the  consummation  of  which  would
     constitute  a Change in  Control,  (ii) the  Executive  terminates  his/her
     employment  for Good Reason prior to a Change in Control  (whether or not a

     Executive  shall not have  returned  to the  full-time  performance  of the
     Executive's  duties  during such thirty (30) day  period),  and (ii) if the
     Executive's  employment  is  terminated  for any  other  reason,  the  date
     specified in the Notice of Termination (which, in the case of a termination
     by the Company, shall not be less than thirty (30) days (except in the case

     of a termination by the Executive, shall not be less than fifteen (15) days
     nor more than sixty (60) days,  respectively,  from the date such Notice of

                         ARTICLE VIII - CLAIMS PROCEDURE

8.1  Filing Claims

     Any insured,  Beneficiary  or other  individual  (hereinafter,  "Claimant")
     entitled to benefits  under the  Agreement  shall file a claim request with

8.2  Notification of Claimant

     If a claim request is wholly or partially denied,  the  Administrator  will
     furnish to the Claimant a notice of the decision  within 90 days in writing
     and in a manner  calculated to be understood by the Claimant,  which notice
     will contain the following information:


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

          (b) Specific  reference to pertinent  provisions of the Agreement upon
     which the denial is based;

          (c) A description of any additional material or information  necessary
     for the  Claimant  to  perfect  the  Claim and an  explanation  of why such
     material or information is necessary; and

          (d) An explanation of the claims review  procedure under the Agreement
     describing  the steps to be taken by a  Claimant  who  wishes to submit his
     claim for review.

8.3  Review Procedure

         Claimant  or his  authorized  representative  may with  respect  to any
denied claims:

          (a) Request a review upon written  application filed within sixty (60)

     claim;

          (b) Review pertinent documents; and

         Any  request or  submission  must be in  writing  and  directed  to the
         Fiduciary,  as  defined  under  Section  9.9,  (or its  designee).  The
         Fiduciary (or its designee) will have the sole  responsibility  for the

     any matter  pertaining to the denied claim)  warrant  additional  time, the
     decision will be rendered as soon as possible,  but not later than 120 days
     after  receipt  of the  request  for  review.  Written  notice  of any such
     extension  will be furnished to the Claimant prior to the  commencement  of
     the extension.

     provisions of the Agreement on which the decision is based.

          (c) If the  decision on the review is not  furnished  to the  Claimant
     within the time limits prescribed above, the claim will be deemed denied on
     review.


                      ARTICLE IX - MISCELLANEOUS PROVISIONS

9.1  Misrepresentation.

          (a) The Company may deem it  appropriate  to insure its  obligation to
     provide all or any part of the benefits described in this Agreement. If the
     Company  does deem it  appropriate  to  insure  all or any part of any such
     benefits, the Company will so notify the Executive. The Executive agrees to
     take  whatever  actions  may be  necessary  to enable the Company to timely
     apply  for,  acquire  and  maintain  such  insurance  and  to  fulfill  the
     requirements of the insurance company relative to the issuance thereof.

          (b) If the Executive is required by the Company to submit  information
     to one or more insurers in order to secure  insurance as described  herein,
     and  if  the  Executive  has  made  a  material  misrepresentation  in  any
     application  for such insurance,  the Executive's  right to a benefit under
     this  Agreement  will be reduced by the amount of the  benefit  that is not
     paid by the insurer(s) because of such material misrepresentation.

9.2  Satisfaction of Claims

     The  Executive  agrees  that his  rights  and  interests,  and  rights  and
     interests of any persons  taking under or through him,  will be  completely
     satisfied  upon  compliance  by the  Company  with the  provisions  of this
     Agreement.

9.3  Amendment; Waiver; Superseding Agreement.

          (a) No  provision  of  this  Agreement  may  be  modified,  waived  or
     discharged  unless such waiver,  modification  or discharge is agreed to in
     writing and signed by the Executive and such officer as may be specifically
     designated  by the Board.  No waiver by either  party hereto at any time of
     any breach by the other party hereto of, or of any lack of compliance with,
     any condition or provision of this  Agreement to be performed by such other
     party  shall be deemed a waiver of  similar  or  dissimilar  provisions  or
     conditions at the same or at any prior or subsequent  time.  This Agreement
     supersedes  any other  agreements  or  representations,  oral or otherwise,
     express or implied,  with respect to the subject  matter  hereof which have
     been made by either party.

          (b) The  Agreement  may be altered,  amended,  or  modified  only by a
     written instrument signed by the Company and the Executive.  This Agreement
     sets forth the entire  understanding  of the  parties  with  respect to the
     subject matter thereof.

9.4  Governing Law

     The  validity,   interpretation,   construction  and  performance  of  this
     Agreement  shall be governed by the laws of the State of  Connecticut.  All
     references to sections of the Exchange Act shall be deemed also to refer to
     any  successor  provisions  to such  sections.  Any  payments  provided for
     hereunder  shall be paid net of any applicable  withholding  required under
     federal,  state or local law and any  additional  withholding  to which the
     Executive has agreed.

9.5  Non-Assignable Rights

     Neither the Executive nor his spouse, nor other Beneficiary,  will have any
     right to commute,  sell, assign,  transfer or otherwise convey the right to
     receive any payments  hereunder without the written consent of the Company.
     Such  payments  and  the  right  thereto  are  expressly   declared  to  be
     non-assignable and nontransferable.

9.6  Independence of Agreement

     The benefits under this  Agreement will be independent  of, and in addition
     to,  any other  agreement  that may exist  from  time to time  between  the
     parties  hereto,  or any other  compensation  payable by the Company to the
     Executive,  whether as salary, bonus or otherwise.  This Agreement will not
     be deemed to  constitute  a contract  of  employment  between  the  parties
     hereto,  nor will any provision hereof restrict the right of the Company to
     discharge  the  Executive,  or  restrict  the  right  of the  Executive  to
     terminate his employment.

9.7  Non-Secured Promise

     The rights of the Executive  under this Agreement and of any Beneficiary of
     the Executive will be solely those of an unsecured creditor of the Company.
     Any insurance  policy or any other asset acquired or held by the Company in
     connection with the liabilities assumed by it hereunder, will not be deemed
     to be  held  under  any  trust  for the  benefit  of the  Executive  or his
     beneficiaries  or to be security for the  performance of the obligations of
     the Company,  but will be, and remain, a general,  unpledged,  unrestricted
     asset of the Company and the Company  will retain all  ownership  rights in
     any such policy.

9.8  Successors; Binding Agreement

     In addition to any  obligations  imposed by law upon any  successor  to the
     Company,  the  Company  will  require  any  successor  (whether  direct  or
     indirect,  by  purchase,  merger,  consolidation  or  otherwise)  to all or
     substantially all of the business and/or assets of the Company to expressly
     assume and agree to perform  this  Agreement  in the same manner and to the
     same  extent  that the  Company  would be required to perform it if no such
     succession  had  taken  place.  Failure  of  the  Company  to  obtain  such
     assumption and agreement prior to the  effectiveness of any such succession
     which is in  connection  with a Change in Control shall be a breach of this
     Agreement and shall entitle the Executive to compensation  from the Company
     in the same amount and on the same terms as the Executive would be entitled
     to hereunder if the Executive were to terminate the Executive's  employment
     for Good Reason  after a Change in Control,  except  that,  for purposes of
     implementing the foregoing,  the date on which any such succession  becomes
     effective  shall be deemed the date of  Termination  of  Employment  of the
     Executive.

9.9  Fiduciary and Administrator

          (a) The Human  Resources  Committee of the Board will be Fiduciary and
     the Company will be Administrator of this Agreement. The Company's Board of
     Directors  may  authorize  a person  or group of  persons  to  fulfill  the
     responsibilities of the Company as Administrator.

          (b) The  Fiduciary or the  Administrator  may employ  others to render
     advice  with  regard to its  responsibilities  under  this  Agreement.  The
     Fiduciary may also allocate  fiduciary  responsibilities  to others and may
     exercise any other powers  necessary for the discharge of its duties to the
     extent not in  conflict  with any  provisions  of the  Employee  Retirement
     Income Security Act of 1974 that may be applicable.

9.10 Waiver by Human Resources Committee

     The  Human  Resources  Committee  of the Board is  authorized  to waive any
     provisions of this Agreement which would otherwise  operate to deny, reduce
     or delay any benefit payments under any provisions of this Agreement.

9.11 Arbitration

     Any dispute or controversy  arising under this Agreement in connection with
     any  termination-related  compensation  or benefit and any such  dispute or
     controversy  in  connection  with a claim for  compensation  or benefits to
     which Article VIII applies  (after  application  of the  provisions of said
     Article  VIII) shall be settled  exclusively  by  arbitration  in Hartford,
     Connecticut  in  accordance  with  the  rules of the  American  Arbitration
     Association  then in effect.  Judgment  may be entered on the  arbitrator's
     award in any court having jurisdiction.

     This CONTINUING SERVICES AND RETIREMENT AGREEMENT  ("Agreement") is made as
of March 3, 2000 by and  between  HSB Group,  Inc.,  a  Connecticut  corporation
("Company"), and Gordon W. Kreh ("Executive").

     WHEREAS,  Executive  has been  employed  by the  Company and certain of its
Affiliates  (as defined in Section 3.1 below) for nearly  twenty-nine  years and
served in various senior  management  positions  prior to being  appointed Chief

     WHEREAS  Executive  has provided  valuable  service to the Company over the
term of his employment; and

     WHEREAS, in order to facilitate an orderly management transition, Executive
has agreed to retire as  President  and Chief  Executive  Officer of the Company
effective  as of  December  31,  1999,  and to retire as  Chairman  of the Board
effective  as of a date on or after the Signing  Date (as defined in Section 1.3

     Executive's  employment following a Change in Control, other than by reason
     of death or  Disability  (as  defined in the SERP),  will be deemed to be a

the Company's  Retiree Life  Insurance Plan and Company's  Retiree  Medical Plan
Executive  shall be deemed to have retired under the Company's  Retirement  Plan
and for purposes of computing the Annual Dollar Limits of Company  contributions
under the Retiree  Medical  Plan,  shall be deemed to be age 55 until the day he
actually reaches age 55 following which Executive's actual age will be used.

     2.2.5 Prorated Awards Under the Long-Term Incentive Plan. Executive will be
entitled to receive the following prorated awards under the Long-Term  Incentive
Plan for the Performance Periods ending in 2000 and 2001:

          (i) 2/3 of the award, if any, he would otherwise have been entitled to
     receive as Chief Executive Officer of the Company based upon the attainment
     of the  Performance  Measures  established  for the  1998-2000  Performance
     Period; and

          (ii) 1/3 of the award,  if any, he would  otherwise have been entitled
     to  receive  as Chief  Executive  Officer  of the  Company  based  upon the
     attainment  of the  Performance  Measures  established  for  the  1999-2001
     Performance Period; provided,  however, Executive will forfeit any right to
     any  award  under  this  Section  2.2.5 if at the time an award is  payable
     Executive is in breach of any of the provisions  contained in Sections 3.1,
     3.2,  3.3 or 3.4 of this  Agreement.  Payment of the awards  will be in the
     form of cash or common stock of the Company  (which may include  restricted
     stock) or a combination  thereof,  at the discretion of the Human Resources
     Committee of the Board of Directors of the Company. Payment will be made at
     the same time as payment is made to other participants under the Plan.

     2.2.6 Restricted Shares under the Company's  Long-Term Incentive Plan. With
respect  to  the  restricted  shares  previously  granted  under  the  Company's
Long-Term  Incentive  Plan (and the special  grant  awarded  outside the plan on
January 26, 1998) listed on Exhibit C to this  Agreement,  the Restricted  Stock
Instruments governing such awards shall be amended as follows:

          (i) the Restricted Period will end on March 3, 2002;

          (ii) the  restrictions on the shares described in the instruments will
     lapse on the  earlier of (x) March 3,  2002,  provided  Executive  is still
     employed  by the Company on such date,  or (y) the date of the  Executive's
     death or Disability, and

          (iii) violation of Sections 3.1, 3.2, 3.3, or 3.4 of this Agreement or
     termination of this  Agreement by the Executive in accordance  with Section
     4.2 will result in forfeiture of all of such shares.

     2.3  Coverage  under the  Rabbi  Trust.  The  Company  agrees  that it will
continue to include any benefits  payable to Executive under the SERP Agreement,
the Top Hat Plan and the Excess  Retirement Plan under the Trust Agreement dated
May 30, 1997 between the Company and Fleet  National Bank until such time as all
benefits payable under such plans have been paid to Executive or his beneficiary
or the trust is terminated  by the Company in  accordance  with the terms of the
Trust Agreement.

     2.4 Acknowledgement by Executive. Executive acknowledges and agrees that in
the event that he revokes his consent to the release  referenced  in Section 5.1
below, he shall have no right to receive any of the payments in this Article II.
Executive  further  acknowledges  that following his receipt of the payments set
forth in this Article II and/or  Article IV below,  as  applicable,  the Company
shall have no further  obligations to him, and he shall have no right to further
compensation,  with respect to his employment with the Company or the separation
therefrom.




                                   ARTICLE III

                             COVENANTS OF EXECUTIVE

     3.1. Confidentiality. Executive agrees that, during the Service Period, and
at all times thereafter,  he shall continue to hold in a fiduciary  capacity for
the benefit of the Company, all secret or confidential information, knowledge or
data relating to the Company and any other  business or entity in which,  at any
relevant time, the Company holds an equity (voting or non-voting) interest equal
to or  greater  than 10% (an  "Affiliate")  that  shall  have been  obtained  by
Executive  during  his  employment  by or  affiliation  with the  Company or its
Affiliates,  and  that  shall  not be  public  knowledge  other  than by acts of
Executive or his representative ("Confidential Material").  Executive shall not,
without the prior written consent of the Chief Executive Officer of the Company,
communicate  or  divulge  any  Confidential  Material  to anyone  other than the
Company and those designated by it.


     3.2. Covenant Not to Compete.  Executive hereby agrees that for a period of
two years from the Signing Date, he will not, directly or indirectly, enter into
any business  relationship (either as principal,  agent, board member,  officer,
consultant, stockholder, employee or in any other capacity) with any business or
other entity that at any relevant  time  competes in any respect with any of the
businesses of the Company or any of its Affiliates in any county in the State of
Connecticut,  the names of all of which  are  deemed  hereby to be  specifically
included  herein by reference,  throughout  the United States and North America,
and anywhere else in the world where the Company or any of its  Affiliates,  has
operations or conducts business (a "Competitor");  provided,  however, that such
prohibited  activity  shall not  include  the  ownership  of less than 1% of the
voting securities of any publicly traded corporation  regardless of the business
of such corporation. Notwithstanding the foregoing, Executive may participate in
private equity or venture capital activities from time to time, provided that in
connection with such activities  Executive may not directly or indirectly  enter
into a business  relationship  with any entity which engages in the underwriting
of equipment breakdown insurance and/or engineering services of the type offered
by the Company or any of its Affiliates.

     3.3.  Solicitation.  Executive agrees that for a period of three years from
the Signing Date, he will not employ,  offer to employ,  engage as a consultant,
or form a business  association  with any person who is then,  or who during the
preceding one year was, an employee of the Company or any Affiliate, nor will he
assist any other person in soliciting for employment or consultation  any person
who is then,  or who during  the  preceding  one year was,  an  employee  of the
Company or any Affiliate.  Notwithstanding the foregoing,  Executive will not be
precluded  from  employing  a  former  employee  of  the  Company  or any of its
Affiliates,  provided that Executive did not directly or indirectly solicit such
employee,  and provided further that such former  employee's date of termination
of  employment  from the Company or its Affiliate was more than six months prior
to the date such person is employed by Executive.

     3.4.  Non-Interference.  Executive  agrees that for a period of three years
from the Signing  Date,  he will not disturb or attempt to disturb any  business
relationship  or agreement  between  either the Company or an Affiliate  and any
other person or entity.

     3.5.  Injunctive Relief.  Executive  acknowledges that his violation of the
foregoing covenants of this Article III could cause the Company irreparable harm
and  he  agrees  that  the  Company  shall  be  entitled  to  injunctive  relief
restraining  Executive from actual or threatened  breach of the  covenants,  and
that if a bond is  required to be posted in order for the Company to secure such
relief,  said bond need only be in a nominal  amount.  Subject  to  Section  3.6
below,  the right of the Company to seek injunctive  relief shall be in addition
to any other  remedies  available  to the Company  with respect to an alleged or
threatened breach.

     3.6. Effect of Covenants.  Nothing in Sections 3.1, 3.2, 3.3, or 3.4 hereof
shall be construed to adversely affect the rights that the Company would possess
in the absence of the provisions of such sections.


                                   ARTICLE IV

                            TERMINATION OF EMPLOYMENT

     4.1.  Termination  of  Employment by Company.  In the event that  Executive
violates any of the provisions of Sections 3.1, 3.2, 3.3 or 3.4, the Company may
terminate Executive's employment by sending a notice of termination to Executive
which shall set forth in reasonable detail the facts and  circumstances  claimed
to provide a basis for  termination  of the  Executive's  employment  under this
Section 4.1. The date the notice is sent in accordance with this Agreement shall
be the effective date of Executive's termination.  In the event that the Company
terminates  Executive's  employment pursuant to the preceding sentence,  (i) the
Base Salary payments will cease  effective as of the termination  date; (ii) any
shares of restricted stock currently  outstanding under the Company's  Long-term
Incentive Plan, the special grant of 2,539 shares awarded outside of the plan on
January 26, 1998,  and the  restricted  shares granted under Section 2.1 will be
forfeited; and (iii) Executive will not be eligible for the Retiree Medical Plan
and Retiree Life Insurance  benefit as provided under Section 2.2.4. The Company
shall not be entitled  to suspend or  terminate  any other  payments or benefits
otherwise due to Executive by reason of  Executive's  violation of Sections 3.1,
3.2, 3.3, or 3.4 (whether  before or after a judgment is obtained by the Company
against  Executive).  Nothing  in this  Section  3.6 shall  limit the  Company's
remedies  in the case of  Executive's  violation  of this  Agreement,  except as
otherwise specifically provided in this Section 4.1.

     4.2  Resignation by Executive.  Executive shall have the right to terminate
his  employment  at any time by  sending a  written  notice  to the  Company  in
accordance with this Agreement specifying the effective date of his termination.
In the event that Executive  provides services to, or assumes a position with, a
for-profit  business without the written consent of the Chief Executive  Officer
of the Company (regardless of whether such business is a Competitor),  Executive
shall be deemed to have resigned from employment  with the Company  effective as
of the date such services commenced.  For purposes of determining the respective
rights and  obligations  of the  parties  under this  Agreement  arising  out of
termination pursuant to this Section 4.2, such termination shall be deemed to be
a termination  by the Company in  accordance  with Section 4.1.  Termination  by
Executive  under  this  Section  4.2  shall  not act to  release  him  from  the
restrictions  set forth in Sections 3.1, 3.2, 3.3. or 3.4.,  without the written
consent of the Chief Executive Officer.

     4.3  Death or  Disability.  In the event  that  Executive's  employment  is
terminated on account of death or Disability,  (i) the Base Salary payments will
cease  effective as of the employment  termination  date; and (ii) any shares of
restricted stock currently  outstanding under the Company's  Long-term Incentive
Plan, the special grant of 2,539 shares  awarded  outside of the plan on January
26,  1998,  and the  restricted  shares  granted  under  Section 2.1 will become
non-forfeitable and freely transferable subject to the requirements contained in
the restricted stock  instruments  governing such restricted  stock awards.  For
purposes  of  this  Agreement  "Disability"  shall  mean a total  and  permanent
Long-Term  Disability  as it is defined in the Company's  Employees'  Disability
Plan, effective January 1, 1976, as from time to time amended.

     4.4 Other  Benefits upon  Termination  of  Employment.  Any other  benefits
payable to Executive or his  beneficiary  shall be determined in accordance with
the terms of the Company's policies, programs and plans in effect on the date of
Executive's  termination of employment under this Article IV taking into account
the  event  giving  rise to the  termination  and  Executive's  age and years of
service as of such termination date.


                                    ARTICLE V

                            MISCELLANEOUS PROVISIONS


     5.1 Release of Claims. The provision by the Company of the compensation and
benefits described under Article II and/or Article IV, as applicable,  hereunder
are conditioned upon Executive's  compliance with the terms described under this
Agreement and the execution,  non-revocation and honoring of a release of claims
and covenant not to sue in favor of the Company in the form  attached  hereto as
Exhibit D.

     5.2. Other  Agreements.  This  Agreement  shall be effective on the Signing
Date. Except as otherwise expressly provided herein, this Agreement  constitutes
the entire agreement  between Executive and the Company and supersedes all prior
agreements and  understandings,  written or oral,  including,  but not by way of
limitation, the Severance Agreement dated February 3, 1997, as amended effective
as of May 24, 1999.

     5.3.  Successors.  This  Agreement is personal to Executive  and may not be
assigned by Executive without the consent of the Company. However, to the extent
that rights or  benefits  under this  Agreement  otherwise  survive  Executive's
death,  Executive's  heirs and estate shall  succeed to such rights and benefits
pursuant to Executive's will or the laws of descent and  distribution;  provided
that Executive shall have the right at any time and from time to time, by notice
delivered  to  the  Company,  to  designate  or to  change  the  beneficiary  or
beneficiaries with respect to such benefits. This Agreement may be assigned to a
successor to all or substantially all of the business or assets of the Company.

     5.4.  Arbitration of All Disputes.  Any controversy or claim arising out of
or relating to this Agreement (or the breach thereof) shall be settled by final,
binding  and  non-appealable  arbitration  in  Hartford,  Connecticut  by  three
arbitrators.  Except as  otherwise  expressly  provided in this Section 5.4, the
arbitration  shall be  conducted  in  accordance  with the rules of the American
Arbitration   Association  (the  "Association")  then  in  effect.  One  of  the
arbitrators  shall be  appointed  by the  Company,  one  shall be  appointed  by
Executive, and the third shall be appointed by the first two arbitrators. If the
first two arbitrators cannot agree on the third arbitrator within 30 days of the
appointment  of the  second  arbitrator,  then  the  third  arbitrator  shall be
appointed by the  Association.  This Section 5.4 shall not be construed to limit
the  Company's  right to obtain  relief under Section 3.5 hereof with respect to
any matter or controversy  subject to Section 3.5 hereof,  and,  pending a final
determination  by the arbitrator with respect to any such matter or controversy,
the Company shall be entitled to obtain any such relief by direct application to
state,  federal or other  applicable  court,  without  being  required  to first
arbitrate such matter or controversy.

     5.5.  Governing Law. This  Agreement  shall be governed by and construed in
accordance with the laws of the State of Connecticut,  without  reference to the
principles of conflict laws.

     5.6.  Amendment.  This  Agreement may only be amended by written  agreement
executed  by  the  parties  hereto  or  their  respective  successors  or  legal
representatives.

     5.7.  Notices.  Notices and all other  communications  provided for in this
Agreement  shall be in  writing  and shall be  delivered  personally  or sent by
registered  or  certified  mail,  return  receipt  requested,   postage  prepaid
(provided  that  international  mail  shall be sent  via  overnight  or  two-day
delivery),  or sent by facsimile or prepaid  overnight courier to the parties at
the addresses set forth below (or such other  addresses as shall be specified by
the  parties  by  like  notice).  Such  notices,   demands,   claims  and  other
communications  shall be deemed given:  (i) in the case of delivery by overnight
service with  guaranteed  next day delivery,  the next day or the day designated
for delivery;  (ii) in the case of certified or registered  U.S. mail, five days
after deposit in the U.S. mail; or (iii) in the case of facsimile, the date upon
which the  transmitting  party  received  confirmation  of receipt by facsimile,
telephone  or  otherwise;  provided,  however,  that in no event  shall any such
communications  be deemed  to be given  later  than the date  they are  actually
received.  Communications  that  are to be  delivered  by the  U.S.  mail  or by
overnight  service  or  two-day  delivery  service  are to be  delivered  to the
addresses set forth below:

         If to Executive:
         Gordon W. Kreh
         133 Westerly Terrace
         Hartford, CT  06105

         If to the Company:
         HSB Group, Inc.
         P.O. Box 5024
         One State Street
         Hartford, CT 06102-5024
         Attn: Corporate Secretary

or to such other  address as either party shall  furnished to the other party in
writing in accordance with the provisions of this Section 5.7.

     5.8  Severability.  It is the  desire and  intent of the  parties  that the
provisions of this Agreement shall be enforced to the fullest extent permissible
under  the  laws and  public  policies  applied  in each  jurisdiction  in which
enforcement  is sought.  In the event that any one or more of the  provisions of
this  Agreement  shall be held to be  invalid,  illegal  or  unenforceable,  the
validity,  legality and  enforceability of the remainder of this Agreement shall
not in any way be affected or impaired thereby.  Moreover, if any one or more of
the provisions contained in this Agreement is held to be excessively broad as to
duration,  scope,  activity or subject,  such  provisions  shall be construed by
limiting  and  reducing  them  so as to be  enforceable  to the  maximum  extent
compatible  with  applicable  law. The  invalidity  or  unenforceability  of any
provision of this  Agreement will not affect the validity or  enforceability  of
any other provision of this Agreement,  and this Agreement shall be construed as
if such invalid or unenforceable  provision were omitted (but only to the extent
such provision can not be appropriately reformed or modified).

     5.9 No Waiver. The failure of either party to this Agreement to enforce any
of its terms,  provisions or covenants shall not be construed as a waiver of the
same or of the right of such party to enforce the same.  Waiver by either  party
hereto of any breach or default by the other party of any term or  provision  of
this  Agreement  shall not  operate as a waiver of any other  breach or default.
This  Agreement  and the  provisions  contained  in it shall not be construed or
interpreted  for or  against  any party to this  Agreement  because  that  party
drafted  or  caused  that  party's  legal  representative  to  draft  any of its
provisions.


     IN WITNESS WHEREOF, Executive has hereunto set his hand and the Company has
caused this Agreement to be executed on its behalf, all as of the Signing Date.

                           RESTRICTED STOCK INSTRUMENT




To:  Gordon W. Kreh

HSB GROUP, INC.
RESTRICTED STOCK INSTRUMENT

Pursuant to the  provisions  of the  Long-Term  Incentive  Plan (the "Plan") HSB
Group, Inc. (the "Company") hereby awards to you (the "Participant"), subject to
the  terms  and  conditions  of the Plan and  subject  further  to the terms and
conditions  herein  set  forth,  25,413  shares of Common  Stock of the  Company
("Restricted Stock").

1.       Terms and  Conditions - It is  understood  that the award of Restricted
         Stock is subject to the following terms and conditions:

         (a)      Restricted  Period  - The  Restricted  Stock  awarded  to  the
                  Participant may not be sold, assigned,  transferred,  pledged,
                  hypothecated  or otherwise  disposed of, except by will or the
                  laws of  descent  and  distribution,  for the  period  of time
                  ending on March 3, 2002 (the "Restricted Period"). Any attempt
                  by  Participant  to  dispose of any such  shares  prior to the
                  expiration of the Restricted Period shall be null and void and
                  without effect.

         (b)      Dividends  and Voting  Rights - The  Restricted  Stock will be
                  registered in the name of the  Participant  and held in escrow
                  by the Human  Resources  Committee  of the Board of  Directors
                  (the  "Committee").  The  Participant  will,  subject  to  the
                  restrictions   contained  in  this  Instrument,   possess  all
                  incidents of ownership of the Restricted Stock,  including the
                  rights to receive  dividends with respect to such stock and to
                  vote such stock.

         (c)      Lapse of  Restrictions  - The  restrictions  on the Restricted
                  Stock  described in  Paragraph  (a) above shall lapse upon the
                  completion  of the  Restricted  Period  and the  Participant's
                  right to such shares shall vest on such date, or if earlier on
                  the  date  that the  Participant's  employment  terminates  on
                  account of death or Disability (as such term is defined in the
                  Plan).

         (d)      Forfeiture - In the event the  Participant's  employment  with
                  the  Company  terminates  for any  reason  other than death or
                  Disability,  or in the event the  Participant  violates any of
                  Sections 3.1, 3.2, 3.3 or 3.4 of the  Continuing  Services and
                  Retirement  Agreement  to which this  instrument  is attached,
                  prior  to  the  expiration  of  the  Restricted   Period,  the
                  Restricted   Stock  shall   thereupon   be  forfeited  by  the
                  Participant  and  transferred to, or reacquired by the Company
                  at no cost to the Company.

         (e)      Delivery of Shares - The Company shall deliver the  Restricted
                  Stock to the  Participant,  or the  Beneficiary (as defined in
                  the Plan) of the  Participant,  if applicable,  within 30 days
                  after the termination of the Restricted Period or, the earlier
                  lapse of restrictions in accordance with Paragraph (c).

2.   Modification - The Committee  shall have the authority to cancel all or any
     portion of any outstanding  restrictions  on the Restricted  Stock prior to
     the  expiration  of the  Restricted  Period  with  respect to the shares of
     Restricted  Stock  awarded  hereunder on such terms and  conditions  as the
     Committee may deem appropriate.

3.   No Right to  Continued  Employment  - This  award  shall  not  confer  upon
     Participant  any right with respect to  continuance  of  employment  by the
     Company, nor shall it interfere in any way with the right of the Company to
     terminate his employment at any time.

4.   No Rights as Shareholder - Except as provided herein, the Participant shall
     not have any  rights as a  shareholder  with  respect  to any shares of the
     Restricted Stock awarded hereby.

5.   Compliance  with Laws and  Regulations - The Company shall not be obligated
     to deliver  stock  pursuant to an award of  Restricted  Stock for which the
     restrictions  hereunder  have lapsed if such  delivery  would  constitute a
     violation of any applicable law. The Committee may postpone the delivery of
     stock  following  the lapse of  certain  restrictions  with  respect to the
     Restricted  Stock for such time as the Committee in its discretion may deem
     necessary,  in order to permit the Company with reasonable diligence (i) to
     effect or maintain  registration of the Plan or the shares deliverable upon
     the lapse of certain  restrictions  respecting  awards of Restricted  Stock
     under the Securities Act of 1933, as amended, or the securities laws of any
     applicable jurisdiction, or (ii) to determine that such shares and the Plan
     are exempt from such registration.

6.   Restrictions  and  Withholding  - The  Committee  shall  have the  right to
     condition  any  delivery  of  shares  pursuant  to  the  lapse  of  certain
     restrictions  with  respect to the  Restricted  Stock on the  Participant's
     undertaking in writing to comply with such  restrictions  on the subsequent
     disposition  of such  shares  as the  Committee  shall  deem  necessary  or
     advisable  as a  result  of any  applicable  law or  regulation.  Upon  the
     delivery of shares of Restricted  Stock pursuant  hereto the Participant or
     other person  receiving  the stock shall be required to pay to the Company,
     the amount of any taxes which the  Company is  required  to  withhold  with
     respect to such stock.  The  Participant  will have the ability to elect to
     have  shares  otherwise  issuable  pursuant  to the  lapse of  restrictions
     withheld, or may deliver previously owned shares to the Company, to satisfy
     such withholding taxes.

7.   Adjustment  - In the event of any  change in the  stock of the  Company  by
     reason   of   any   stock   dividend,   stock   split,    recapitalization,
     reorganization,  merger, consolidation,  split-up, combination, or exchange
     of shares,  or rights  offering to purchase stock at a price  substantially
     below Fair Market Value (as defined in the Plan),  or of any similar change
     affecting  the  common  stock of the  Company,  the  number  of  shares  of
     Restricted Stock awarded herein with respect to which restrictions have not
     lapsed shall be appropriately  adjusted consistent with such change in such
     manner  as the  Board in its  discretion  may  deem  equitable  to  prevent
     substantial  dilution or enlargement of the rights granted to, or available
     for, all  participants  in the Plan. Any fractional  shares  resulting from
     such adjustments shall be eliminated. Any adjustment so made shall be final
     and binding upon the Participant.

8.   Participant Bound by Plan - Participant  acknowledges  receipt of a copy of
     the Plan and shall be bound by all the terms and provisions thereof.

9.   Notices - Any notice  hereunder  to the  Committee  shall be  addressed  as

                    RELEASE OF CLAIMS AND COVENANT NOT TO SUE

This RELEASE OF CLAIMS AND COVENANT NOT TO SUE (the  "Release")  is executed and
delivered  by  GORDON  W.  KREH  (the  "Executive")  to  HSB  GROUP,  INC.  (the
"Company").  In  consideration  of the  agreement  by the Company to provide the
Executive with the rights,  payments and benefits under the Continuing  Services

2000 (the  "Agreement")  to which the Executive would not otherwise be entitled,
the Executive hereby agrees as follows:

Section  1.  Release  and  Covenant.  The  Executive,  of  his  own  free  will,
voluntarily   releases  and  forever   discharges  the  HSB  Group,   Inc.,  its
subsidiaries,  affiliates, directors, officers, employees, agents, stockholders,
successors and assigns,  both  individually  and in their  official  capacities,
(collectively  referred to as  "Releases")  from,  and  covenants  not to sue or
proceed  against  any of the  foregoing  on the  basis  of,  any and all past or
present causes of action, suits, agreements or other claims which the Executive,
his dependents,  relatives,  heirs,  executors,  administrators,  successors and
assigns has or have  against any of them upon or by reason of any matter,  cause
or thing whatsoever,  including,  but not limited to, any matters arising out of
his  employment by the Company and the  termination of his position as Chairman,
President and Chief  Executive  Officer of the Company (and as an officer and/or
director of various subsidiaries and affiliates of the Company),  and including,
but not limited to, any alleged  violation  of the Civil Rights Acts of 1964 and

Connecticut Human Rights and Opportunities  Law, each as amended,  and any other
federal or state law,  regulation or ordinance,  or public  policy,  contract or
tort law having any bearing whatsoever on the terms and conditions of employment
or  termination  of employment.  This Release shall not,  however,  constitute a
waiver of any vested  pension  rights of Executive,  or be construed to prohibit
Executive  from  bringing  appropriate  proceedings  to enforce this  Agreement.
Executive  further  agrees that he will not seek or be entitled to any  personal
recovery  in any claim,  charge,  action or  proceeding  whatsoever  against the
Company or any of the Releases for any of the matters set forth in this Release.

consult with an attorney prior to executing this Release.  The Executive  enters
into this Release having freely and knowingly elected,  after due consideration,

Release  shall be revocable by the Executive  during the 7-day period  following
its execution by delivering  (by hand or overnight  courier)  written  notice of
revocation to R. Kevin Price,  Corporate Secretary at HSB Group, Inc., One State
Street,  Hartford,  Connecticut  06102-5024  and shall not become  effective  or
enforceable  until the  expiration of such 7-day period.  In the event of such a
revocation,  the Executive shall not be entitled to the  consideration  for this
Release set forth above.

Section 3.  Reliance by  Executive.  The  Executive  acknowledges  that,  in his
decision to enter into this Release,  he has not relied on any  representations,
promises or agreements of any kind, including oral statements by representatives
