ITEM 1. BUSINESS
 
GENERAL
 
    HCC Insurance Holdings, Inc. ("HCC") is a Delaware corporation with
principal and executive offices located at 13403 Northwest Freeway, Houston,
Texas 77040. HCC and its consolidated subsidiaries are collectively referred to
herein as the "Company" unless the context otherwise requires. HCC, through its
subsidiaries, provides specialized property and casualty insurance coverages,
underwriting agency and intermediary services and other insurance related
services both to commercial customers and individuals. The Company's insurance
products are underwritten on both a direct and reinsurance basis and are
marketed by the Company and through a network of independent and affiliated
agents and brokers. The Company's principal insurance company subsidiaries are
Houston Casualty Company ("HC") in Houston, Texas, London, England and Amman,
Jordan; U.S. Specialty Insurance Company ("USSIC") in Houston, Texas; and Avemco
Insurance Company ("AIC") in Frederick, Maryland. The principal underwriting
agency subsidiaries are LDG Reinsurance Corporation ("LDG Re") in Wakefield,
Massachusetts; HCC Aviation Insurance Group, Inc. ("HCCA") in Dallas, Texas and
Glendale, California; HCC Employer Services, Inc. ("HCCES") in Northbrook,
Illinois, Dallas, Texas and Montgomery, Alabama; and HCC Benefits Corporation
("HCCB") in Atlanta, Georgia, Wakefield, Massachusetts, Minneapolis, Minnesota
and Kansas City, Kansas. The Company's principal intermediary subsidiaries are
HCC Intermediaries, Inc. ("HCCI") in Houston, Texas; HCC Employee Benefits, Inc.
("HCCEB") in Houston, Texas; and, effective January 1, 1999, Rattner Mackenzie
Limited ("RML") in London, England and Amman, Jordan.
 
    Since its founding in 1974, the Company and its predecessor companies have
been consistently profitable, generally reporting annual increases in gross
written premium ("GWP"), management fees, commission income and total revenue.
During the period 1996 through 1998, the Company's insurance company
subsidiaries had an average combined ratio of 81.8% versus the less favorable
103.7% recorded by the U.S. property and casualty insurance industry overall
(1996-1997). During the same period, the Company's GWP increased from $337.3
million to $498.3 million, an increase of 48%, management fees increased from
$28.7 million to $74.0 million an increase of 158%, commission income increased
from $21.5 million to $38.4 million, an increase of 79% and net earnings
increased from $38.6 million to $72.3 million, an increase of 87%.
 
    The Company's insurance companies' underwriting activities are focused on
providing aviation, marine, offshore energy, property, medical stop-loss,
accident and health, workers' compensation and lenders' single interest
insurance and reinsurance on a worldwide basis. As an insurer in the USA, the
Company operates on a surplus lines or a non-admitted basis through HC and on an
admitted basis through AIC and USSIC.
 
    The Company's domestic insurance company subsidiaries are rated "A+"
(Superior) by A.M. Best Company ("A.M. Best") and are rated "AA" (Very Strong)
by Standard & Poor's Corporation ("S&P"). An A.M. Best or S&P rating is intended
to provide an independent opinion of an insurer's ability to meet its
obligations to policyholders and should not be considered as an investment
recommendation.
 
    The Company's underwriting agencies underwrite on behalf of affiliated and
non-affiliated insurance companies. These agency operations specialize in
domestic general aviation insurance, medical stop-loss coverage for employer
sponsored self-insured health plans, occupational accident coverage for
self-insured truckers, workers' compensation insurance and a variety of accident
and health related insurance and reinsurance products. Beginning in 1996 with
the acquisition of LDG Management Company, Incorporated ("LDG"), the Company
commenced a strategy of acquiring through merger or purchase, a number of
privately held companies whose business was underwriting agency activities,
primarily in the medical stop-loss, workers' compensation and domestic general
aviation insurance businesses. This was done in an effort to further diversify
the Company's operations and to enhance the Company's ability to anticipate
 
                                       3
<PAGE>
and capitalize on opportunities resulting from changing market conditions in the
insurance industry. As a result of these acquisitions, the Company's management
fees from underwriting agencies have increased to $74.0 million. The Company's
underwriting agency operations generated $704.0 million in written premium
during 1998. Further acquisitions are likely in the area.
 
    Brokerage operations are performed by the Company's intermediary
subsidiaries. The Company's intermediary operations consist of marketing,
placing, consulting on and servicing insurance risks for its clients, which
include insurance companies and other risk taking entities. The Company's
intermediary subsidiaries specialize in employee benefits on a retail basis and
reinsurance for both accident and health and property and casualty clients. The
Company significantly expanded its intermediary operations internally and
through acquisition in 1998 and continued this expansion in January, 1999 with
the acquisition of PEPYS Holdings Limited ("PEPYS") and its operating
subsidiary, RML. Since 1995, the Company's commission income from its
intermediary operations has increased from $5.9 million (prior to
pooling-of-interests restatements) to $38.4 million. Further acquisitions are
contemplated.
 
    Two subsidiaries of the Company perform insurance related services for
customers of the Company's insurance and agency subsidiaries and for unrelated
entities. These services include insurance claims adjustment and servicing and
computer software development and sales.
 
    From time to time the Company will make strategic operational investments,
generally in companies or operations in or related to the insurance industry.
Certain of these investments are intended to enhance the Company's operations
through strategic partnering in areas common to the investee and the Company.
The Company's revenue from these investments is comprised of equity in earnings
of the investee, dividends and gains on the sale of these investments.
 
STRATEGY
 
    The Company's operating philosophy as an insurer is to maximize underwriting
profits while preserving shareholders' equity. The Company concentrates its
writings in selected, narrowly defined lines of business in which it believes
there is a substantial opportunity to achieve underwriting profits. The Company
primarily underwrites first party coverages and lines of business which have
relatively short lead times between the occurrence of an insured event and the
reporting of claims to the Company. The Company's insurance products are
marketed both directly and through independent and affiliated agents. With
respect to its underwriting management, marketing and related services, the
Company seeks to offer quality underwriting, decision-making, support,
reinsurance capacity and financial and other resources to take advantage of
market opportunities for the development of new products.
 
    The property and casualty insurance underwriting business has historically
been cyclical (though mainly not seasonal) and within the overall cycle of the
industry, particular lines of business experience their own cycles. These cycles
are characterized by periods of excess capital and significant competition in
policy pricing, terms and conditions, followed by periods of capital shortages,
typically resulting from adverse loss experience, which leads to decreased
competition, higher premium rates and stricter underwriting standards.
 
    The position of a particular line of business in its respective underwriting
cycle depends on prevailing premium rates, availability and cost of reinsurance,
and other market conditions. The Company considers each of these factors in
determining when to increase or decrease premium volume in each line. With this
approach, the Company focuses on increasing net earnings rather than premium
volume or market share.
 
    The Company purchases a substantial amount of reinsurance to limit its net
loss from both individual and catastrophic risks. The degree to which the
Company reinsures varies by, among other things, the particular risks inherent
in the policies underwritten, pricing of available reinsurance and competitive
conditions within the relevant line of business.
 
                                       4
<PAGE>
    In its insurance company operations, the Company believes its operational
flexibility, experienced underwriting personnel and access to and expertise in
the reinsurance marketplace allow the Company to implement its strategy of
emphasizing more profitable lines of business during periods of increased
premium rates and de-emphasizing less profitable lines of business during
periods of severe competition. In addition, through its acquisition and
ownership of insurance underwriting agencies and intermediary businesses, the
Company believes that those service based businesses can both complement the
Company's underwriting activities and serve as a source of revenue which may not
be subject to the same level of volatility as traditional underwriting revenues.
Many of the Company's insurance underwriting agency and intermediary
subsidiaries act as agents or intermediaries on behalf of the Company's
insurance company subsidiaries as well as for non-affiliated insurers or other
risk taking entities. Additionally, a claims adjusting and servicing subsidiary
provides services for the insurance company subsidiaries and their customers.
The ability of the Company's insurance company subsidiaries to utilize an
affiliated insurance underwriting agency, intermediary or services provider, and
the corollary ability of such insurance underwriting agency, intermediary and
services subsidiaries to place business with or provide other services to an
affiliated insurer, permits the Company to earn a greater portion of the total
income derived from generated premium.
 
    The Company's business plan is to expand its underwriting activities and
continue the growth of its insurance underwriting agency and intermediary
operations. The Company will also, from time to time, make strategic operational
investments in companies that present an opportunity for future profit from sale
or for enhancement of the Company's business. However, the Company's business
plan is shaped by its underlying operating philosophy, which is to maximize
underwriting profit opportunities, while preserving shareholders' equity. The
Company expects to continue to seek to acquire complementary businesses with
established management and reputation in the insurance industry, whose business,
the Company believes, can be enhanced through the synergism created by the
Company's underwriting capabilities and its other owned insurance related
businesses. As a result, the Company's primary interests are not necessarily in
expanding market share or GWP, but rather in increasing net earnings. To
accomplish this objective, the Company: (i) has been and is prepared to
emphasize or reduce underwritings in certain lines of business as premium rates,
the availability and cost of reinsurance and other market conditions warrant;
(ii) will continue to attempt to limit its downside net loss exposure through
the effective, prudent and conservative use of reinsurance; (iii) will, as
conditions warrant, emphasize the growth of its insurance underwriting agency
and intermediary operations, which can be expected to result in continuing
growth of management fees and commission income as a portion of total revenues;
and (iv) will continue to review the possible acquisition of other specialty
insurance companies and of other strategic operational investments that may,
after a period of growth, increase in value or that represent strong strategic
partners.
 
INDUSTRY SEGMENT INFORMATION
 
    Financial information concerning the Company's operations by industry
segment is set forth in the Consolidated Financial Statements and the Notes
thereto.
 
MAJOR ACQUISITIONS
 
    On May 24, 1996, the Company issued 6,250,000 shares of its Common Stock to
acquire all of the outstanding shares of LDG. LDG, now operating as LDG Re, acts
on behalf of insurance and reinsurance companies as a reinsurance underwriting
manager in the following lines of business: accident and health special risks
and alternative workers' compensation. LDG Re generally concentrates on lines of
business that have relatively short lead times between the occurrence of an
insured event and the reporting of claims.
 
    On November 27, 1996, the Company issued 1,136,400 shares of its Common
Stock and paid $1.7 million in cash to acquire all of the outstanding shares of
North American Special Risks Associates, Inc. ("NASRA"). NASRA, now known as
HCCES, provides underwriting management and claims
 
                                       5
<PAGE>
administration services to insurance and reinsurance companies primarily for
occupational accident insurance for self-employed truckers and alternative
workers' compensation insurance.
 
    On June 17, 1997, the Company issued 8,511,625 shares of its Common Stock
and 604,575 options to purchase its Common Stock in order to acquire all of the
outstanding shares and options to purchase shares of Avemco Corporation
("Avemco"), the parent corporation of a group of insurance and insurance
services companies. Avemco, through its insurance company subsidiaries, provides
property and casualty insurance in the general aviation, lenders' single
interest and short-term health lines of business. Avemco's primary insurance
company subsidiaries were AIC and USSIC. Following the acquisition, the
operations of USSIC have been relocated to Houston, Texas and it has become a
subsidiary of HC. AIC and USSIC operate on an admitted basis throughout the
United States and AIC also operates as an admitted insurer in Canada (except
Quebec).
 
    Avemco's principal insurance underwriting agency and services operations are
focused in three areas: (i) underwriting management services for lenders' single
interest coverage for banks and other financial institutions; (ii) underwriting
management services for short-term health and travel insurance marketed to
foreign students and others resident in the United States; and (iii) insurance
related computer products, software and services for property and casualty
insurance companies throughout the United States.
 
    On February 27, 1998, the Company issued 1,600,000 shares of its Common
Stock to acquire all of the outstanding shares of The Kachler Corporation
("Kachler"), now known as HCCEB. Kachler was a retail insurance agency
specializing in life, accident and health insurance for employee benefit plans
of medium and large commercial customers throughout the United States.
 
    On January 31, 1999, the Company acquired all of the outstanding stock of
PEPYS. PEPYS is the sole shareholder of RML. The total initial consideration was
$54.8 million in cash and deferred payments of $8.3 million in cash and 414,207
shares of the Company's Common Stock. Additional amounts may be paid in the
future based upon the attainment of certain earnings benchmarks over the next
four years. RML, the operating entity, provides intermediary services for
reinsurance business placed by the Company's insurance company subsidiaries as
well as unaffiliated insurance and reinsurance companies and underwriting
agencies.
 
PENDING ACQUISITIONS
 
    There are currently no acquisitions pending; however, the Company is
evaluating a number of possible acquisition candidates and expects to complete
one or more acquisitions during the remainder of 1999. The Company believes
these future acquisitions will expand and strengthen its existing lines of
business and perhaps provide access to additional specialty sectors, which
management expects will contribute to the growth of the Company.
 
INSURANCE COMPANY OPERATIONS
 
    The Company's property and casualty insurance company businesses specialize
in underwriting aviation, marine, offshore energy, property, medical stop-loss,
accident and health, workers' compensation and lenders' single interest risks.

</TABLE>
 
UNDERWRITING
 
    DIRECT--The Company underwrites direct business produced through independent
agents and brokers, affiliated intermediaries, and by direct marketing efforts,
primarily in small general aviation business.
 
    REINSURANCE--The Company's current reinsurance underwriting activities are
primarily in the accident and health lines of business where the Company's
insurance company subsidiaries participate in various insurance and reinsurance
underwriting pools managed by its underwriting agency subsidiaries and
facultative (individual account) reinsurance, particularly in the aviation and
property lines of business.
 
    The Company underwrites facultative reinsurance in most of its lines of
business. Typically, this is on international business in order to comply with
local licensing requirements or as reinsurance of captives, and usually can be
considered direct business, as the Company maintains underwriting and claims
control. However, all of this business is recorded under the caption of
"Reinsurance Assumed".
 
    AVIATION--Aviation underwriting presently represents the Company's largest
overall line of business and in recent years the Company has grown into a market
leader in the aviation insurance industry. The Company insures general aviation
risks, including private aircraft owners and pilots, fixed base operations,
rotor wing aircraft, corporate aircraft, cargo operations, commuter airlines and
similar operations, both
 
                                       7
<PAGE>
domestically and internationally. At this time, the Company does not generally
insure major airlines, major manufacturers or satellites. The coverages
underwritten include hull (including engines, avionics and other systems),
liabilities, war, cargo and various ancillary coverages.
 
    The Company has been underwriting aviation risks since 1981 through HC. AIC
has been insuring aviation risks since 1959. GWP has risen consistently since
1996, increasing from a combined $140.7 million to $203.6 million in 1998. This
growth has occurred due to internal growth and acquisitions. Although, due to
market conditions, domestic risks had not been a focus for the Company since the
early 1990's, HC increased its writing of domestic general aviation risks late
in 1996 and with the acquisition of AIC and USSIC in mid-1997, the Company
achieved the position of a major participant in the domestic general aviation
insurance market. The Company's position is further enhanced by its subsidiary
aviation underwriting agency operations which underwrite on behalf of affiliated
and non-affiliated insurance companies. In 1998 and 1997, the Company
experienced a decline in NWP due to the implementation of the Company's
reinsurance program at AIC following its acquisition in 1997.
 
    Reinsurance is maintained on both a proportional and an excess of loss basis
to protect the Company against individual risk severity of loss and catastrophe
exposure. Management believes that the aviation risks underwritten by the
Company carry a relatively low level of catastrophe exposure.
 
    MARINE--The Company underwrites marine risks for ocean going vessels ("Blue
Water"), inland and coastal trading vessels ("Brown Water"), fishing vessels.
The coverages written include hull and machinery, liabilities (including
protection and indemnity), marine cargo and various ancillary coverages.
 
    The Company has underwritten marine risks since 1984. Premium rates were
adequate during 1995 but competition has created downward pressure on these
rates causing a reduction in the Company's GWP from $32.4 million in 1996 to
$13.3 million in 1998 and a corresponding decrease in NWP from $25.9 million to
$5.7 million for the same period.
 
    Reinsurance is maintained on an excess of loss basis to protect the Company
against individual risk severity of loss and catastrophe exposure. Management
believes that the marine risks underwritten by the Company carry a relatively
low level of catastrophe exposure.
 
    OFFSHORE ENERGY--The Company has been underwriting offshore energy risks
since 1988. Offshore energy risks include drilling rigs, production and
gathering platforms, and pipelines. Coverages underwritten include physical
damage, liabilities, business interruption and various ancillary coverages.
 
    Rates have declined significantly during the past few years to levels where
underwriting profitability is unlikely. Underwriting has been on a very
selective basis, striving for quality rather than quantity. The increase in GWP
and NWP during 1998 was the result of one large policy.
 
    Reinsurance is maintained on both a proportional and an excess of loss basis
to protect the Company against individual risk severity of loss and the
catastrophic exposure that exists, for example, from a hurricane in the Gulf of
Mexico.
 
    PROPERTY--The Company specializes in writing risks of large, often
multinational corporations, covering such commercial risks as hotels, office
buildings, retail locations, factories, industrial plants, utilities,
refineries, natural gas facilities and petrochemical plants. Coverage includes
business interruption, physical damage and catastrophe risks including flood and
earthquake.
 
    The Company has written property business since 1986. GWP increased to
$118.2 million in 1996 as premium rates increased following the Northridge
earthquake in 1994. During 1996, premium rates began to soften and this trend
has continued through 1998 due in a large part to excess capacity and the
absence of significant catastrophe losses. GWP has declined from $118.2 million
in 1996 to $106.5 million in 1998. NWP also declined from $16.4 million to $8.4
million in the same period. Property NWP will always be substantially less than
GWP due to the amount of facultative reinsurance and reinsurance purchased in
order to protect the Company from catastrophe exposure.
 
                                       8
<PAGE>
    Reinsurance is maintained on both a proportional and an excess of loss basis
to ensure adequate protection, particularly against catastrophic exposures. As
an example, in 1998 the Company had gross losses of $53.7 million with respect
to hurricanes Georges and Mitch. The after-tax net loss, after reinsurance, with
respect to these hurricanes was $3.8 million. The Company conservatively
estimates its aggregate exposure in any individual catastrophe zone and
maintains catastrophe reinsurance to cover its exposure to any one occurrence.
 
    ACCIDENT AND HEALTH REINSURANCE--The Company began underwriting accident and
health reinsurance risks through HC during 1996. These risks are produced
primarily by LDG Re, the underwriting agency which was acquired by the Company
during that year. The risks underwritten include reinsurance in the accident and
health special risks and alternative workers' compensation areas and
occupational accident insurance for self-employed truckers. The Company's GWP
increased from $11.1 million in 1996 to $115.4 million in 1998. This growth is
from the Company's increased participation in various insurance and reinsurance
pools managed by its underwriting agency subsidiaries.
 
    Management believes that its accident and health reinsurance business
carries a relatively low level of catastrophe exposure.
 
    MEDICAL STOP-LOSS--Medical stop-loss business is written on an aggregate and
specific basis for employer sponsored self-insured health plans. The business is
produced by an underwriting agency subsidiary of the Company. The Company first
began writing this business in 1996 and GWP has increased, as a result of
greater participation by an insurance company subsidiary in the business
underwritten by an underwriting agency subsidiary which produces this business.
 
    LENDERS' SINGLE INTEREST--USSIC began writing lenders' single interest risks
in 1984. GWP decreased from $22.9 million in 1996 to $17.9 million in 1998 due
to a competitive market. Due to the implementation of a new reinsurance program
when USSIC was acquired in June, 1997, (part of the Avemco merger) NWP decreased
even further from $19.7 million in 1996 to $6.6 million in 1998. This coverage
is marketed to banks and other financial institutions and addresses risks of
physical loss or damage to the property collateralizing installment loans
(primarily automobiles). All of the lenders' single interest risks underwritten
by the Company are produced by the Company's subsidiary, Avemco Financial
Services, Inc. ("AFS").
 
    Reinsurance is maintained on a proportional basis to protect against
frequency of loss. Management believes that its lenders' single interest
business carries a relatively low level of catastrophe exposure.
 
    WORKERS' COMPENSATION--The Company began writing statutory workers'
compensation business in 1998 and expects to expand these writings significantly
through HCCES. It is the intent of the Company to grow this line of business in
the future internally and through acquisition. GWP will increase as an insurance
company subsidiary of HCC serves as a policy issuing company for HCCES's
business. The Company currently reinsures this business, except for a small
retention. Losses in this line of business generally take longer to develop than
in the Company's other lines of business, but, due to the Company's reinsurance,
management does not believe that the longer development period will adversely
affect the Company's underwriting results.
 
INSURANCE COMPANY SUBSIDIARIES
 
    HOUSTON CASUALTY COMPANY--HC, the Company's principal insurance company
subsidiary, is rated A+, VIII by A.M. Best and AA by Standard & Poor's and
operates worldwide in most of the lines of business in which the Company
specializes. HC's business is produced by independent agents and brokers, the
group's underwriting agency and intermediary subsidiaries, AIC, USSIC, the
Company's subsidiary Trafalgar Insurance Company ("TIC"), and other insurance
and reinsurance companies worldwide. HC has a highly experienced staff of
underwriters trained to deal with the high value, complicated exposures
prevailing in many of the lines of business in which the Company specializes. As
of December 31, 1998, HC had statutory policyholders' surplus of $262.4 million.
 
                                       9
<PAGE>
    HOUSTON CASUALTY COMPANY--LONDON--HC was authorized by Her Majesty's
Treasury in 1998 to operate a full branch office in the United Kingdom. HC is in
the process of staffing this branch and expects it to become fully operational
towards the end of 1999. HC established the branch in London in order to be
closer to some of the markets in which HC operates and to have access to a
larger pool of insurance talent. The Company intends to transfer underwriting
responsibility for all lines of business HC writes, except aviation, to this
branch. HC-London initially began writing accident and health business in early
1999 through Feasey Slot Management, Ltd., an underwriting agency in which the
Company has a strategic investment.
 
    HOUSTON CASUALTY COMPANY--JORDAN--HC also established a branch operation in
Amman, Jordan in 1998 with the assumption of all of the business of IMG
Insurance Company Ltd. ("IMG"). IMG, formerly a subsidiary of the Company, was
liquidated in 1998. Due to the similar nature of IMG's business to that written
by HC, management determined that an HC branch operation in Jordan rather than
an independently capitalized subsidiary would be a more productive and efficient
utilization of the Company's capital. Additionally, management believes that
this action can be expected to enhance the direct presence of HC in the Middle
Eastern, Asian and African markets and is expected to lead to increased
underwriting opportunities for the Company.
 
    TRAFALGAR INSURANCE COMPANY--TIC, which was organized in 1993, is a wholly
owned subsidiary of HC. TIC, an Oklahoma domiciled property and casualty
insurance company, is rated A+, V by A.M. Best. TIC currently underwrites
primarily domestic property risks and was historically utilized by HC to offer
insurance on a surplus lines basis in certain jurisdictions where HC is not
otherwise permitted to do so. As of December 31, 1998, TIC had statutory
policyholders' surplus of $15.2 million, a decrease of $15.7 million from
December 31, 1997 due to a special dividend paid to HC. As a result of changes
in the operations of the Company's insurance company subsidiaries, including the
relocation and change in focus of USSIC's operations, management has determined
that TIC is no longer a necessary component of the Company's insurance company
operations and intends to effect the disposition of TIC during 1999. Its
business will be transferred to other insurance company subsidiaries of the
Company.
 
    U.S. SPECIALTY INSURANCE COMPANY--USSIC is a Texas domiciled property and
casualty insurance company and former subsidiary of AIC, which became a direct
subsidiary of HC in December, 1997. The Company was re-domesticated from
Maryland to Texas in 1998. USSIC is rated A+, VII by A.M. Best and AA by
Standard & Poor's and has historically been an underwriter of general aviation
and lenders' single interest risks through a network of independent agents.
USSIC operates on an admitted basis throughout the United States. The Company
expects to continue USSIC's operation, primarily writing general aviation and
workers' compensation insurance produced by underwriting agency subsidiaries of
the Company. During December, 1998, the Company increased the policyholders'
surplus of USSIC by $32.5 million and as of December 31, 1998, USSIC had
statutory policyholders' surplus of $79.2 million.
 
    AVEMCO INSURANCE COMPANY--AIC was organized in 1959 and became a subsidiary
of the Company in June, 1997. AIC is a Maryland domiciled property and casualty
insurer, is rated A+, VII by A.M. Best and AA by Standard & Poor's and operates
primarily as a direct market underwriter of general aviation business on an
admitted basis throughout the United States and Canada (except Quebec) and as an
insurer of lenders' single interest risks produced by AFS. In addition, as a
part of the Company's overall operations, AIC has become an insurer of medical
stop-loss products underwritten by an underwriting agency subsidiary of the
Company. At December 31, 1998, AIC had statutory policyholders' surplus of
$104.9 million.
 
UNDERWRITING AGENCY OPERATIONS
 
    The Company's underwriting agency subsidiaries act on behalf of insurance
and reinsurance companies, conducting business in the areas of insurance
underwriting management and claims administration. The underwriting agency
subsidiaries do not assume any insurance or reinsurance risk themselves and the
 
                                       10
<PAGE>
revenues generated are based entirely on management fees and profit commissions.
These subsidiaries are in a position to direct and control business that they
produce. In addition, certain of the business written by the underwriting
agencies is insured or reinsured by the Company's insurance company
subsidiaries. In some cases, the insurance company subsidiaries serve as policy
issuing companies for this business. The insurance company subsidiaries may
retain a portion of the risk and reinsure the remainder with other unaffiliated
insurance companies or reinsure all of the risk.

these services primarily consists of fees, commissions or the sales price of
product sold. The two subsidiaries currently operating in this segment provide
insurance claims adjusting services and development and sale of insurance
industry related software. Additionally, other operations include the returns
received from certain insurance related strategic operational investments which
the Company makes from time to time. Certain of these investments provide
strategic partnering opportunities. These returns may be in the form of equity
in the earnings of the investee, dividends or gains from the disposition of
these investments.
 
    Other operating income was $22.3 million in 1998, up 46% from 1997.
 
COMBINED INSURANCE COMPANY AND UNDERWRITING AGENCY OPERATIONS
 
    The Company's combined GWP was over $1.0 billion in 1998 with its insurance
company operations underwriting $498.3 million and its underwriting agency
operations underwriting $704.0 million.

REINSURANCE CEDED
 
    The Company principally utilizes reinsurance to reduce its net liability on
individual risks, to protect against catastrophic losses and to achieve a
desired ratio of NWP to policyholders' surplus. Various intermediaries,
including HCCI and RML, facilitate the placement of this reinsurance coverage on
behalf of the Company and are compensated, directly or indirectly, by the
reinsurers.
 
    Reinsurance is ceded on both a proportional and an excess of loss basis.
Management believes that the Company reinsures its risks to a greater extent
than most of its competitors and most other insurance companies. This strategy
greatly reduces the likelihood of a significant net loss from insurance company
operations and protects the Company's shareholders' equity. Under its current
reinsurance protections, the Company has limited its net retained loss, across
any single line of business, to a maximum of approximately $1.0 million for any
one risk, but significantly less on most risks.
 
    The type, cost and limits of reinsurance purchased can vary from year to
year based upon the Company's desired retention levels and the availability of
adequate reinsurance at a reasonable price. The Company's reinsurance programs
renew throughout the year. Programs that expired in 1998 have been renewed at
comparable costs.
 
    The availability of reinsurance continues to be an important part of the
Company's business plan, protecting Shareholders equity from catastrophe losses
and the inconsistencies of the insurance cycle. Important relationships have
been built up over the years with many core Reinsurers who have supported the
Company in good and bad times. The Company will continue to share its business
with these partners when underwriting profitability returns, to allow them to
recoup losses and build even stronger relationships in the future. Increased
retentions during profitable periods is made possible not at the sacrifice of
core Reinsurers, but, through reduction of facultative reinsurance and the
natural attrition of certain Reinsurers who exit lines of business, severely
curtail their writings or become insolvent. This reduction in reinsurance market
capacity causes rates to rise but the increased rates historically have been
passed on to the primary market clients.
 
    The Company structures a specific reinsurance program for each line of
business it underwrites. This reinsurance is placed in order to protect the
Company from exposure to foreseeable events. The Company places reinsurance
proportionally to cover loss frequency and catastrophe exposure on an excess of
loss basis to cover individual risk severity of loss and catastrophe exposure
from occurrences involving multiple risks, such as those resulting from a
hurricane or an earthquake. The Company does not intend to expose itself to any
net loss in excess of its reinsurance protection.
 
    The Company writes business in areas exposed to catastrophic losses and has
significant exposures to this type of loss in California, the Atlantic Coast of
the United States, certain United States Gulf Coast states, particularly in
Florida and Texas, the Caribbean and Mexico. The Company carefully assesses its
overall exposures to a single catastrophic event and applies procedures that it
believes are more conservative than are typically used by the industry to
ascertain the Company's probable maximum loss ("PML") from any single event. The
Company maintains reinsurance protection which it believes is sufficient to
cover any foreseeable event.
 
    The Company receives an overriding (ceding) commission on the premium ceded
to reinsurers which compensates the Company for the direct costs associated with
the production of the premium, the servicing of the business during the term of
the policies ceded and the costs associated with the placement of the related
reinsurance. In addition, certain of the Company's reinsurance treaties allow
for a sharing with the Company by the reinsurers of any net profits generated
under such treaties.
 
    The ceding of reinsurance does not discharge the Company from liability to
its policyholders. The Company is required to pay losses even if the reinsurer
fails to meet its obligations under the reinsurance contract. To minimize its
exposure to reinsurance credit risk, the Company places its reinsurance with a
diverse group of financially sound reinsurers. The Company's 1999 treaty
reinsurance program was placed
 
                                       13
<PAGE>
with more than 52 domestic and foreign reinsurers. As of December 31, 1998, the
total amount recoverable from reinsurers was approximately $372.7 million, of
which $33.6 million represents paid losses recoverable (in the ordinary course
of business) and $341.6 million represents outstanding losses recoverable, less
a $2.5 million reserve for uncollectible reinsurance. In addition, ceded
unearned premium was $149.6 million. At December 31, 1998, the Company held
$166.5 million of irrevocable letters of credit and $8.1 million in cash to
collateralize a portion of the total amount recoverable and had other payable
balances due to its reinsurers of $227.6 million as potential offsets against
reinsurance recoverables. The estimated duration for the Company's outstanding
losses is two years, as the majority of the Company's business has historically
had shorter lead times between the occurrence of an insured event and the final
settlements. The following table shows reinsurance balances relating to the
reinsurers with a total recoverable balance greater than $10.0 million and the
collateral and potential offsets held by the Company as of December 31, 1998:

*   Underwriters Indemnity Company was acquired by RLI Corporation, an insurance
    holding company, (NYSE: RLI) in January, 1999.
 
    Prior to the Company's acquisition of Avemco, AIC retained a greater
percentage of overall premiums written than HC and TIC. Following the
acquisition, the Company implemented a program of reinsurance for AIC which is
more consistent with the reinsurance programs utilized by the Company's other
insurance company subsidiaries. The effect of this change was to limit the net
retained exposure of AIC, to reduce net earned premium and to reduce the effect
on net earnings of large losses and a high frequency of losses.
 
    Due to the Company's financial analysis of active and potential reinsurers
and its conservative strategy of diversifying its reinsurers, the Company has
never incurred a significant loss on recoverables from reinsurers. The Company
has established a reserve of $2.5 million as of December 31, 1998, which is
intended to reduce the effects of any recoverable problem. However, the adverse
economic environment in the insurance industry has placed great pressure on
reinsurers and the results of their operations. These conditions could,
ultimately, affect reinsurers' solvency. Historically, there have been
insolvencies following a period of competitive pricing in the industry, such as
the marketplace is experiencing today. Therefore, while management believes that
the reserve is adequate, conditions can change or additional information might
be obtained that would affect management's estimate of the adequacy of the level
of the reserve, and which may result in a future increase or decrease in the
reserve.

    While there is no statutory requirement regarding a permissible premium to
surplus ratio, guidelines established by the National Association of Insurance
Commissioners ("NAIC") provide that a property and casualty insurer's annual
statutory GWP should not exceed 900% and NWP should not exceed 300% of its
policyholders' surplus. In keeping with its philosophy of protecting its
shareholders' equity and limiting its aggregate loss exposure, the Company
maintains premium to surplus ratios significantly lower than such guidelines,
and, as indicated above, below industry norms.

    The SAP basis ratio data is not intended to be a substitute for results of
operations on the basis of generally accepted accounting principles ("GAAP").
The differences between SAP and GAAP are shown in Note (15) of the Company's
consolidated financial statements. Including this information on a SAP basis is
meaningful and useful to allow a comparison of the Company's operating results
with those of other companies in the insurance industry. A.M. Best reports on

RESERVES
 
    Applicable insurance laws and regulations require that reserves be
maintained for the payment of loss and loss adjustment expense ("LAE") with
respect to both reported and incurred but not reported ("IBNR") claims under
insurance and reinsurance policies issued by the Company's insurance company
subsidiaries. In most cases, the Company establishes reserves through an
evaluation of individual claims. In some types of aviation claims, an average
reserving method is utilized until more information becomes available which will
permit a more specific individual evaluation of claims. In the case of direct
and facultative reinsurance business, loss reserves are determined by evaluating
reported claims on the basis of the type of loss, jurisdiction of the
occurrence, knowledge of the circumstances surrounding the claim, severity of
injury or damage, potential for ultimate exposure, experience with the insured
and the line of business and policy provisions relating to the particular type
of claim. The Company establishes loss reserves for excess of loss and
proportional reinsurance claims based on information and reports received from
ceding companies. Loss reserves for IBNR losses are determined in part on the
basis of statistical information and in part on industry experience with respect
to the probable number and nature of claims arising from occurrences which have
not been reported. The Company does not discount any of its loss reserves.
 
    With respect to some classes of risks, the period of time between the
occurrence of an insured event and the final settlement of a claim may be many
years, and during this period it often becomes necessary to adjust the claim
estimates either upward or downward. Certain classes of marine and offshore
energy insurance and workers' compensation insurance underwritten by the Company
have historically had longer lead times between the occurrence of an insured
event, reporting of the claim to the Company, and final settlement. In such
cases, the Company is forced to estimate reserves over long periods of time,
with the possibility of several adjustments to reserves. Other classes of
insurance, such as most aviation, property and accident and health business the
Company underwrites, historically have shorter lead times between the occurrence
of an insured event, reporting of the claim to the Company and final settlement.
The reserves with respect to such classes are, therefore, less likely to be
adjusted. The classes of insurance with shorter lead times currently represent
the majority of the risks underwritten by the Company's insurance company
operations.
 
    The reserving process is intended to provide implicit recognition of the
impact of inflation and other factors affecting loss payments by taking into
account changes in historical payment patterns and perceived probable trends.
However, there is no precise method for the subsequent evaluation of the
adequacy of the consideration given to inflation, or to any other specific
factor, some of which are interdependent.
 
    The Company underwrites, directly and through reinsurance, risks which are
denominated in a number of foreign currencies, and therefore establishes and
maintains loss reserves with respect to these policies in the respective
currencies. These reserves are subject to exchange rate fluctuations, which may
have an effect on the Company's earnings. From time to time, the Company may
attempt to limit its exposure to future currency fluctuations through the use of
foreign currency forward contracts.
 
    The following loss development triangles show changes in reserves in
subsequent years from the prior loss estimates based on experience as of the end
of each succeeding year on the basis of GAAP. The estimate is increased or
decreased as more information becomes known about the frequency and severity of
losses for individual years. A redundancy means the original estimate was higher
than the current estimate; a deficiency means that the current estimate is
higher than the original estimate.
 
    The first line of each loss development triangle presents, for each of the
years indicated, the gross reserve liability including the reserve for IBNR
losses. The first section of each table shows, by year, the cumulative amounts
of loss and LAE paid as of the end of each succeeding year. The second section
sets forth the re-estimates in later years of incurred losses, including
payments, for the years indicated. The "cumulative redundancy (deficiency)"
represents, as of December 31, 1998, the difference between the latest
re-estimated liability and the reserves as originally estimated.

    During 1998 the Company had gross loss and LAE deficiency of $33.5 million
compared to deficiencies of $23.2 million in 1997 and $42.5 million in 1996. The
gross deficiency comes from two primary sources. Firstly, the development of
several large claims on individual policies which were either reported late or
reserves were increased as subsequent information became available. However, as
most of these policies were substantially reinsured, there was no material
effect to the Company's net earnings. Secondly, the run-off of the
retrocessional excess of loss business which the Company underwrote between 1988
and 1991. This development is due primarily to the delay in reporting of
catastrophe losses by the London insurance market, coupled with the
unprecedented number of catastrophes during the period in which the Company
underwrote this business. This business is also substantially reinsured, thereby
not having a material effect on the Company's net earnings.

    prior years, reflect the net effect of the resolution of losses for other
    than the reserve value and the subsequent adjustments of loss reserves.
 
    Although the Company experienced a gross loss deficiency during the three
years ended December 31, 1998, because the business is substantially reinsured
in the lines where adverse development has occurred, there is no material
adverse effect on a net loss basis.
 
    During 1998, the Company had net loss and LAE redundancy of $14.6 million
relating to prior year losses compared to redundancies of $3.8 million in 1997
and $4.9 million in 1996. The redundancies in the net reserves result from the
Company's and its actuaries continued review of its loss reserves and the
reduction of such reserves as losses are finally settled and claims exposures
are reduced. The Company believes it has provided for all material net incurred
losses.
 
                                       19
<PAGE>
    AIC, acquired in June, 1997, recorded a $10.0 million increase in loss and
LAE reserves during December, 1997, predominately related to 1995 and 1996
claims incurred prior to the Company's acquisition of AIC. This deficiency is
included in the net redundancy recorded for 1997. This increase in reserves was
made in an effort to bring AIC's reserving practices consistent with the more
conservative method used by the Company's other insurance company operations.
The Company expects the increase in loss reserves to be adequate to cover any
subsequent adverse development of AIC's prior losses.
 
    The Company has no material exposure to environmental pollution losses, as
HC only began writing business in 1981 and policies issued by HC normally
contain pollution exclusion clauses which limit pollution coverage to "sudden
and accidental" losses only, thus excluding intentional (dumping) and seepage
claims. Policies issued by AIC and USSIC, because of the types of risks insured,
principally general aviation, are not considered to have significant
environmental exposures. Therefore, the Company should not experience any
material development in reserves from environmental pollution claims.
 
INVESTMENTS
 
    Insurance company investments must comply with applicable laws and
regulations which prescribe the type, quality and concentration of investments.
In general, these laws and regulations permit investments, within specified
limits and subject to certain qualifications, in Federal, state and municipal
obligations, corporate bonds, preferred and common equity securities. As of
December 31, 1998, the Company had $525.6 million of investment assets, the
majority of which were held by its insurance company subsidiaries.
 
    The Company's investment policy is determined by the Company's Board of
Directors and is reviewed on a regular basis. Pursuant to its investment policy,
the Company concentrates its investments in obligations of states,
municipalities and political subdivisions, the interest income from which is
predominantly exempt from Federal income tax. The interest rates on these
securities are normally lower than rates on comparable taxable securities. The
Company's portfolio of fixed income securities available for sale principally
consists of intermediate term, tax-exempt securities. The Company generally
intends to hold such securities to maturity. However, the Company regularly
re-evaluates its position based upon market conditions, which may cause the
Company to restructure its portfolio and realize gains or losses in order to
maximize its total return on investments. Accordingly, all fixed income
securities are classified as available for sale and are recorded at market
value.
 
    The Company's financial statements reflect an unrealized ("mark-to-market")
gain on fixed income securities available for sale as of December 31, 1998, of
$18.1 million. Since the Company's intention is to hold these securities until
maturity, it does not currently expect to realize any significant gain or loss
on these investments.
 
    The Company has maintained a substantial level of cash and liquid short-term
instruments in its insurance company subsidiaries in order to maintain the
ability to fund large physical damage losses of the Company's insureds, should
they occur. As of December 31, 1998, the Company had cash and short-term
investments of approximately $145.1 million of which $70.6 million are in the
Company's insurance company subsidiaries.

BANK LOAN
 
    On March 8, 1999, the Company entered into a Loan Agreement (the "Facility")
with a group of banks. The Facility includes a $150 million Revolving Loan
Facility and $100 million Short Term Revolving Loan Facility. Borrowing under
the Facility may be made from time to time by the Company for general corporate
purposes through the Short Term Revolving Loan Facility until its expiration on
March 7, 2000 and through the Revolving Loan Facility until its expiration on
February 28, 2002. Outstanding loans under the Facility bear interest at agreed
upon rates. The Facility is collateralized in part by the pledge of the stock of
HC, AIC, and USSIC and by the pledge of stock and guaranties entered into by the
Company's principal underwriting agency and intermediary subsidiaries. The
Facility agreement contains certain restrictive covenants, including, without
limitation, minimum net worth requirements for the Company and certain
subsidiaries, restrictions on certain extraordinary corporate actions, notice
requirements for certain material occurrences, and required maintenance of
specified financial ratios. Management believes that the restrictive covenants
and other obligations of the Company which are contained in the Facility
agreement are typical for financing arrangements comparable to the Facility. The
initial funding available under the Facility was used, among other things, to
refinance existing indebtedness of the Company including all outstanding
indebtedness under the Company's $120.0 million revolving credit facility
entered into as of December 30, 1997, which has been terminated.
 
    As of March 13, 1999, total debt outstanding under the Facility was $176.0
million with $150.0 million due under the $150.0 million Revolving Loan Facility
and $26.0 million due under the $100.0 million Short Term Revolving Loan
Facility. The increase in debt subsequent to December 31, 1998 resulted from the
funding of the purchase price of acquisitions.

FOREIGN EXCHANGE
 
    The Company's balances denominated in foreign currency fluctuate as
transactions are recorded and settled. From time to time, the Company has
entered into foreign currency forward contracts as a hedge against foreign
currency fluctuations. Such activity has been on a very limited basis in the
past. The Company did not hedge this risk in 1998, and there were no open
foreign currency forward contracts as of December 31, 1998. In the future, the
Company may limit its exposure to currency fluctuations through the use of
foreign currency forward contracts. The Company utilizes these foreign currency
forward contracts strictly as a hedge against existing exposure to foreign
currency fluctuations and it does not do so as any form of speculative or
trading investment.
 
COMPETITION
 
    The insurance business is generally highly competitive. The Company faces
competition from domestic and foreign insurers and underwriting agency and
intermediary operations, many of whom are larger and have greater financial,
marketing and management resources than the Company. The Company's profitability
is affected by many other factors, including rate competition, severity and
frequency of claims, interest rates, state regulations, court decisions, the
judicial climate and general business conditions, all of which are outside the
control of the Company. Although as an insurer, the Company's underwriting
strategy is to concentrate its writings in selected, narrowly defined lines of
business, the Company faces competition in these selected lines of business both
from other specialty insurance companies as well as larger, more diversified
insurance companies which underwrite multiple lines of business, including the
lines of business underwritten by the Company. The Company's medical stop-loss
business involves a diversified field of participants from small, start-up
operations to large, well-established organizations. Significant growth in the
number of medical stop-loss insurance underwriters and underwriting managers in
the past several years has increased the level of competition in this area of
the Company's business. The Company also faces intense and growing pressure in
this area from alternatives to employer sponsored self-insured health plans,
such as fully-insured plans, HMOs and Point of Service plans, as well as from
large well established direct insurers and competing underwriting managers
providing similar medical stop-loss products to those offered by the Company to
employer sponsored self-insured health plans.
 
    Competition in the reinsurance marketplace is primarily due to an increase
in the number of reinsurers participating in the market as well as a tendency by
reinsureds to retain a greater percentage of their own risk. The Company
competes with other reinsurance underwriting managers and domestic and
international reinsurance companies. The Company's results of operations may
also be affected by the competition for reinsurance business between broker
reinsurance markets and direct marketing reinsurance companies. The Company also
competes with many reinsurance intermediaries in the broker reinsurance market,
some of which are affiliated with primary insurance brokers with substantial
financial resources. In its underwriting agency and services operations, the
Company competes with a large number of publicly traded and private firms which
operate as independent insurance agencies or insurance services providers as
well as with insurance companies which market insurance products directly
through their employees or affiliated insurance agencies. In each of the
business areas in which the Company is engaged, a significant number of the
Company's competitors have financial resources, employees, facilities, market
recognition, marketing, management, experience, and other resources
substantially greater than those of the Company. In addition to competition in
the operation of its business, the Company faces competition from a variety of
sources in attracting and retaining qualified employees.
 
REGULATION
 
    The activities of the Company are subject to licensing requirements and
extensive regulation under the laws of the United States and its various states,
territories and possessions, as well as the laws of other countries in which the
Company's subsidiaries operate. Currently, insurance companies are generally not
subject to any Federal regulation of their insurance business because of the
existence of a Federal law
 
                                       22
<PAGE>
commonly known as the McCarran-Ferguson Act, which provides the insurance
industry with immunity from certain aspects of the Federal anti-trust law and
exempts the business of insurance from Federal regulation. Therefore, in the
United States, the Company's operations are regulated primarily at the state
level. The Company's business depends on the validity of, and continued good
standing under, the licenses and approvals pursuant to which it operates, as
well as compliance with pertinent regulations. The Company therefore devotes
significant efforts toward obtaining and maintaining its licenses and compliance
with a diverse and complex regulatory structure.
 
    The Company's insurance subsidiaries, in common with other insurers, are
subject to regulation and supervision by the states and by other jurisdictions
in which they do business. Within the states, the method of such regulation
varies but generally has its source in statutes that delegate regulatory and
supervisory powers to an insurance official. The regulation and supervision
relates primarily to approval of policy forms and rates, the standards of
solvency that must be met and maintained, including risk based capital
measurements, the licensing of insurers and their agents, the nature of and
limitations of investments, restrictions of the size of risks which may be
insured under a single policy, deposits of securities for the benefit of
policyholders, methods of accounting, periodic examinations of the affairs of
insurance companies, the form and content of records of financial condition
required to be filed, and reserves for unearned premiums, losses and other
purposes. In general, such regulations are intended primarily for the protection
of policyholders rather than shareholders. Compliance is monitored by the state
insurance departments through periodic regulatory reporting procedures and
periodic examinations. The quarterly and annual financial reports to the
regulators in the United States utilize accounting principles which are
different from the GAAP used by the Company in its reports to shareholders. SAP,
in keeping with the intent to assure the protection of policyholders, is
generally based on a liquidation concept while GAAP is based on a going-concern
concept.
 
    In addition to the regulatory supervision of the insurance company
subsidiaries of the Company, as an insurance holding company, the Company is
subject to regulation under the insurance holding company system regulatory acts
in the states of California, Maryland, Missouri, Oklahoma and Texas, which
contain certain reporting requirements including registration and the filing of
annual reports. In such registration and annual reports, the Company is required
to provide current information regarding its capital structure, general
financial condition, ownership, management, and the identity of each member of
its insurance holding company system. The Company is also required to provide
prior notice to insurance regulatory authorities of certain agreements and
transactions between the Company and its affiliates. These agreements and
transactions must satisfy certain standards set forth in the insurance laws and
regulations of such states. Insurance holding company laws also regulate the
payment of dividends and other distributions by insurance companies to their
shareholders.
 
    Additionally, the underwriting agency, intermediary and services operations
of the Company are subject to state insurance laws and regulations which may
require the licensing of insurance agents, brokers, reinsurance intermediaries,
reinsurance underwriting managers, third party administrators and underwriting
agents and which regulate certain aspects of their business. These laws and
regulations may include requirements for certain provisions in contracts entered
into between the Company and various insurers or reinsurers, record keeping and
reporting requirements, limitations on authority, advertising and business
practice rules, and other matters. The manner of operating the Company's agency
activities in particular states may vary according to the licensing requirements
of the particular state, which may require, among other things, that a firm
operate in the state through a local corporation. In a few states, licenses are
issued only to individual residents or locally-owned business entities. In such
cases, the Company has arrangements with residents or business entities licensed
to act in the state.
 
    There can be no assurance given that the Company has all such required
licenses, approvals or complying contracts or that such licenses, approvals or
complying contracts can always be obtained or continued. In all jurisdictions,
the applicable laws and regulations are subject to amendment or interpretation
by regulatory authorities. Generally, such authorities are vested with
relatively broad discretion to
 
                                       23
<PAGE>
grant, renew and revoke licenses and approvals, and to implement regulations,
and licenses may be denied or revoked for various reasons, including the
violations of such regulations, conviction of crimes and the like. In some
instances, the Company follows practices based on its interpretations, or those
that it believes may be generally followed by the industry, of laws and
regulations, which may be different from the requirements or interpretations of
regulatory authorities. Accordingly, the possibility exists that the Company may
be precluded or temporarily suspended from carrying on some or all of its
activities or otherwise penalized in a given jurisdiction. Such preclusion or
suspension could have a materially adverse effect on the business and results of
operations of the Company.
 
    HC is domiciled and licensed as an admitted insurer in Texas, is an
accredited reinsurer in 35 states (including Texas), and is an approved surplus
lines insurer or is otherwise permitted to write surplus lines insurance in 46
states, three U.S. territories and the District of Columbia. When a reinsurer
obtains accreditation from a particular state, insurers within that state are
permitted to obtain statutory credit for risks ceded to the reinsurer. Surplus
lines insurance is offered by non-admitted (unlicensed) companies on risks which
are not insured by admitted (licensed) companies. All surplus lines insurance is
written through licensed surplus lines insurance brokers, who are required to
ensure that no licensed admitted insurer will write a particular risk prior to
placing that risk with a surplus lines insurer. Additionally, HC through its
operations in Amman, Jordan (formerly IMG), is able under Jordanian law to
directly underwrite non-Jordanian risks and reinsure Jordanian risks. In
December, 1998, HC received regulatory approval to operate a full branch office
in the United Kingdom. Such approval will impose additional regulatory
requirements on HC, but management expects that such approval will also permit
HC to take advantage of increased opportunities in the London insurance market,
a historical focal point for specialty property and casualty risks. AIC is
domiciled and licensed as an admitted insurer in Maryland and operates as a
licensed admitted insurer in all other states, the District of Columbia, and all
Canadian provinces (except Quebec). USSIC is domiciled and licensed as an
admitted insurer in Texas and operates as a licensed admitted insurer in all
other states and the District of Columbia. TIC is domiciled and licensed as an
admitted insurer in Oklahoma, is an accredited reinsurer in three states
(including Oklahoma), and is an approved surplus lines insurer or is otherwise
permitted to write surplus lines insurance in 33 states and the District of
Columbia.
 
    Under the laws of the State of Texas, HC and USSIC must maintain minimum
statutory capital of $1.0 million and minimum statutory surplus of $1.0 million
and may only pay dividends out of statutory earned surplus. The maximum amount
of dividends that HC and USSIC may pay without prior regulatory approval in any
12 month period is the greater of each of their statutory net income for the
prior year, or 10% of each of their statutory policyholders' surplus as of the
prior year end. The maximum amount each company could pay as dividends at
December 31, 1998, was $38.2 million and $7.9 million, respectively. Under the
laws of the State of Maryland, AIC may only pay dividends out of its statutory
earned surplus. The maximum amount of dividends that AIC may pay without prior
regulatory approval in any 12 month period is the greater of its statutory net
income (under certain conditions) or 10% of its statutory policyholders'
surplus. The maximum amount at December 31, 1998 was $10.5 million. Under the
laws of the State of Oklahoma, TIC may only pay dividends out of surplus funds.
The maximum amount TIC may pay HC without prior regulatory approval is the
greater of statutory net income excluding realized capital gains or 10% of
statutory capital and surplus. That amount at December 31, 1998 was $2.2
million. On December 31, 1998, TIC paid a special dividend of $15.3 million to
HC, as approved by state regulatory authorities. As a result of this
transaction, any dividends by TIC during the period ended December 31, 1999
would require the prior approval of the Oklahoma Department of Insurance.
 
    The NAIC has developed a formula for analyzing insurance companies called
risk-based capital. The risk-based capital formula is intended to establish
"minimum" capital threshold levels that vary with the size and mix of a
company's business. It is designed to identify companies with the capital levels
that may require regulatory attention. As of December 31, 1998, each of the
Company's domestic insurance
 
                                       24
<PAGE>
company subsidiaries' total adjusted capital is significantly in excess of the
NAIC authorized control level risk-based capital.
 
    The NAIC has also developed a rating system, the Insurance Regulatory
Information System ("IRIS"), primarily intended to assist sate insurance
departments in overseeing the financial condition of all insurance companies
operating within their respective states. IRIS consists of eleven key financial
ratios that address various aspects of each insurer's financial condition and
stability. The Company's insurance company subsidiaries IRIS ratios generally
fall within the usual prescribed ranges except in satisfactorily explainable
circumstances such as when there is a large reinsurance transaction, capital
change or merger.
 
PENDING OR PROPOSED LEGISLATION
 
    In recent years, state legislatures have considered or enacted laws that
modify and, in many cases, increase state authority to regulate insurance
companies and insurance holding company systems. The majority of state insurance
regulators are members of the NAIC, which seeks to promote uniformity of, and to
enhance the state regulation of, insurance. In addition, the NAIC and state
insurance regulators, as part of the NAIC's state insurance department
accreditation program, have re-examined existing laws and regulations,
specifically focusing on insurance company investments, issues relating to the
solvency of insurance companies, licensing and market conduct issues,
interpretations of existing laws, the development of new laws, and the
definition of extraordinary dividends. Also, Congress and certain Federal
agencies have conducted investigations of the current condition of the insurance
industry in the United States to determine whether to impose Federal regulation
of insurers and reinsurers. In the past several years there have been a number
of recommendations that the McCarran-Ferguson Act (which generally exempts the
insurance business from Federal regulation) be repealed entirely or modified to
remove the industry's anti-trust exemption and subject it to Federal regulation.
If the McCarran-Ferguson Act were to be repealed or modified, state regulation
of the insurance business would continue. This could result in an additional
layer of Federal regulation. In addition, in recent years, various measures have
been proposed at the Federal level to reform the current process of Federal and
state regulation of the financial services industries in the United States,
which are generally considered to include the banking, insurance and securities
industries. Such measures, which are often referred to as financial services
modernization, have as a principal objective the elimination or modification of
current regulatory impediments to cross-industry combinations involving banks,
securities firms and insurance companies. It is likely that some form of
financial services modernization legislation will eventually be enacted at the
Federal level which could have significant implications on the banking,
insurance and securities industries. If enacted, such legislation could result
in significant cross-industry consolidations among banks, insurance companies
and securities firms and increased competition in many of the areas of the
Company's operations. Also from time to time, Congress and certain states have
considered various legislative proposals which would provide for governmental
earthquake insurance coverage. The Company does not know at this time the extent
to which any or all such Federal or state legislative or regulatory initiatives
will or may be adopted, and no assurance can be given that they would not, if
adopted, have a material adverse effect on the Company or its results of
operations.
 
    The NAIC adopted Statements of Statutory Accounting Principles ("SSAPs") in
March, 1998 as a product of its attempt to codify statutory accounting
principles. While subject to adoption by the individual states, the NAIC has
established an effective date of January 1, 2001 for the SSAPs. Prior to the
codification project, a comprehensive guide to statutory accounting principles
did not exist. Codification is new and will evolve over time. Based upon the
SSAPs as currently published, the Company does not expect their adoption to have
a material effect on the policyholders' surplus of its individual insurance
company subsidiaries. The only material effect on statutory net income is that
the statutory net income for HC will be decreased or increased by a change in
the method of recording equity in earnings or losses of subsidiaries. Currently
HC records the equity in earnings or losses of its subsidiaries as a component
of statutory net income. When codification becomes effective, the equity in
earnings or losses of subsidiaries
 
                                       25
<PAGE>
will be recorded as an unrealized gain or loss which is a direct increase or
decrease to policyholders' surplus. Income will not be recognized until such
time (if any) that dividends are received from the subsidiaries and recorded in
statutory net income.
 
EMPLOYEES
 
    As of December 31, 1998, the Company had 1,085 employees, which included
five executive officers, 51 senior management, 93 management and 936 other
personnel. Of this number, 241 were employed by the Company's insurance
subsidiaries, 587 were employed by the Company's underwriting agency
subsidiaries, 93 were employed by the Company's insurance intermediary
subsidiaries and 164 were employed by the Company's insurance services
subsidiaries. The Company is not a party to any collective bargaining agreement
and has not experienced work stoppages or strikes as a result of labor disputes.
The Company considers relations with its employees to be good.

ITEM 2. PROPERTIES
 
    The Company's principal and executive offices are located in Houston, Texas,
in an approximately 52,000 square foot building owned by HC. HC also owns an
81,000 square foot building, acquired in 1998, adjacent to its home office
building. The Company also maintains sales and administration offices or other
facilities in over 30 locations elsewhere in the United States and in England,
Turkey and Jordan. The majority of these additional locations are in leased
facilities.
 
    Principal office facilities of the Company, other than HC's owned

ITEM 3. LEGAL PROCEEDINGS
 
    The Company is a party to numerous claims and lawsuits which arise in the
normal course of its business. Many of the pending lawsuits involve claims under
policies underwritten or reinsured by the Company, the liabilities for which
management believes have been adequately included in its established loss
reserves. The Company believes the resolution of these lawsuits will not have a
material adverse effect on its financial condition, results of operations or
cash flows.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

DIVIDENDS
 
    Beginning in June, 1996, the Company announced a planned quarterly program
of paying cash dividends to shareholders. The Company paid a cash dividend in
July, 1996 of $0.02 per share and in each succeeding quarter until the first
quarter of 1997. The Company increased the quarterly cash dividend to $0.03 per

March 8, 1999 to $0.05 per share beginning in April, 1999. The Board of
Directors may review the Company's dividend policy from time to time, and any
determination with respect thereto will be made in light of regulatory and other
conditions then existing, including the Company's earnings, financial condition,
capital requirements, loan covenants, and other related factors. Under the terms
of the Company's March 8, 1999 Facility, the Company is prohibited from paying
dividends in excess of an agreed upon maximum amount in any fiscal year. Such
limitation will not affect the ability of the Company to pay dividends in a
manner consistent with its past practice and current expectations.

(1) On February 27, 1998, the Company acquired all of the outstanding stock of
    Kachler. This business combination has been accounted for as
    pooling-of-interests and, accordingly, the consolidated financial data shown
    in this table has been restated to include the accounts and operations of
    Kachler for all periods presented.
 
(2) These amounts have been adjusted to reflect the effects of the three-for-two
    stock split payable as a 50% stock dividend to shareholders of record March
    15, 1994, and the five-for-two stock split payable as a 150% stock dividend
    to shareholders of record April 30, 1996.
 
(3) Book value per share is calculated by dividing shares outstanding into total
    shareholders' equity. Net tangible book value per share uses total
    shareholders' equity less goodwill as the numerator.
 
(4) Certain amounts in the 1997, 1996, 1995 and 1994 selected consolidated
    financial data have been reclassified to conform to the 1998 presentation.
    Such reclassifications had no effect on the Company's net earnings,
    shareholders' equity, or cash flows.

GENERAL
 
    The Company's primary sources of revenue are earned premium and investment
income derived from its insurance company operations, management fees generated
from its underwriting agency operations, commission income produced by its
intermediary operations and other operating income. The Company's core
underwriting activities involve providing aviation, marine, offshore energy,
property, medical stop-loss, accident and health, workers' compensation and
lenders' single interest insurance, which is underwritten on both a direct and a
reinsurance basis, marketed directly by the Company and produced by independent
agents. Many of the Company's lines of business have relatively short lead times
between the occurrence of an insured event and the reporting of claims to the
Company.
 
    During recent years, the Company has substantially increased its
shareholders' equity through the issuance of equity securities, incurrence of
debt, and earnings, thereby enabling it to increase the underwriting capacity of
its insurance company subsidiaries. The Company has utilized this additional
equity by increasing underwriting activity across many of its core lines of
business, emphasizing lines of business and individual opportunities with the
most favorable underwriting characteristics at a particular point in time. In
each line of business, as an insurer, the Company also cedes premium through the
purchase of reinsurance in types and amounts appropriate to the line of
business, market conditions and the Company's desired net risk retention
profile.
 
    The Company's underwriting agency operations underwrite domestic general
aviation, medical stop-loss, occupational accident, workers' compensation,
accident and health insurance and reinsurance business.
 
    The Company's intermediary operations also place insurance and reinsurance
for the Company's insurance company and underwriting agency operations and other
non-affiliated insurance companies and risk taking entities, as well as on
behalf of medium to large corporate clients.
 
                                       31
<PAGE>
    Since 1996, the Company has focused its acquisition activities on expanding
its underwriting agency and intermediary operations for three principal reasons.
Firstly is an attempt to increase the management fees and commission income
components of the Company's total revenue, which management believes to be a
more predictable and more stable source of revenue than the potential
underwriting gain from insurance company operations. Secondly, an effort to
insulate the Company from a decline in its net earnings growth rate as insurance
premium rates become more competitive in the lines of business in which the
Company specializes in and the Company becomes more selective in its
underwriting approach, resulting in reduced earned premium. Thirdly, to provide
a future source of premium revenue to the Company's insurance company
subsidiaries.
 
    Operations whose revenue are included in other operating income consist of
insurance services operations which may support the Company's operations as well
as service unaffiliated customers. Additionally, this revenue includes revenue
from strategic operational investments and gains and losses from their
disposition. The Company may make such strategic operational investments from
time to time, generally in businesses that complement the Company's operations.
 
RESULTS OF OPERATIONS
 
    The following table sets forth certain premium revenue information for the
three years ended December 31, 1998 (dollars in thousands):

<PAGE>
YEAR ENDED DECEMBER 31, 1998 VERSUS YEAR ENDED DECEMBER 31, 1997
 
    Total revenue increased 10% to $308.0 million in 1998 from $280.3 million in
1997. GWP increased 44% to $498.3 million in 1998 from $346.4 million in 1997,
due primarily to increased aviation, property and accident and health premium.
NWP for 1998 decreased to $121.9 million from $142.9 million in 1997, due to an
increase in the amount of ceded reinsurance. Net earned premium decreased to
$143.1 million in 1998 compared to $162.6 million in 1997 reflecting the
reduction in NWP and the reduced retentions of the Company. Management expects
GWP to increase significantly during 1999 primarily due to internal growth as
the Company's underwriting agency subsidiaries transfer business from
non-affiliated insurance companies to the Company's insurance company
subsidiaries. NWP will increase also, due to the increase in GWP, although at a
lower rate due to the continued low retention of risk. Net earned premium is
expected to decrease slightly in 1999, irrespective of the expected increase in
NWP, due to decreased retentions in 1998 which affect 1999 earned premium.
 
    Management fees in 1998 increased 45% to $74.0 million from $51.0 million in
1997, reflecting internal growth and the acquisition of several underwriting
agencies during the period. The Company expects management fees to continue to
increase substantially during 1999 due to the effects of recent and future
acquisitions and internal growth.
 
    Commission income increased to $38.4 million in 1998 from $24.2 million in
1997 an increase of 59%. The increase is a result of internal growth and a
number of large transactions. Commission income is expected to grow in 1999,
primarily as a result of the acquisition of RML in January, 1999.
 
    Net investment income increased 6% to $29.3 million in 1998 from $27.6
million in 1997 reflecting a slightly higher level of investment assets. In
1998, the Company also utilized a substantial amount of its non-insurance
company subsidiary cash flow to reduce debt and therefore interest expense,
limiting the amount of cash subject to short-term investment. Management expects
to follow this strategy in 1999, which, together with expected lower interest
rates will produce investment income comparable to 1998.
 
    Net realized investment losses from sales of equity securities were $166,000
during 1998, compared to losses of $154,000 in 1997. Net realized investment
gains from disposition of fixed income securities were $1.0 million during 1998,
compared to losses of $174,000 in 1997. The gains in 1998 resulted principally
from the sale of bonds upon the liquidation of IMG.
 
    Other operating income increased from $15.2 million in 1997 to $22.3 million
in 1998, principally as a result of a $4.0 million pre-tax gain on the sale of
one of the Company's subsidiaries whose operations were not material to those of
the Company. Additionally, revenue of a service company subsidiary increased
$2.0 million in 1998.
 
    Policy acquisition costs, which are net of ceding commissions on reinsurance
ceded, decreased $2.6 million or 19% between 1998 and 1997. The decrease
reflects a lower level of retained premium.
 
    Operating earnings for 1998 were impacted by Hurricanes Georges and Mitch.
The gross loss from these hurricanes amounted to more than $50.0 million before
reinsurance, with Georges being the largest catastrophe loss ever incurred by
the Company. The net retained loss after reinsurance and taxes was $3.8 million,
or $0.08 per share. This catastrophe further demonstrates how the Company's
conservative reinsurance philosophy protects shareholders' equity and limits the
impact of a major catastrophe loss. To further mitigate against subsequent
catastrophes, the Company currently maintains lower retentions and anticipates
further reductions in overall catastrophe exposure in the future.
 
    AIC, acquired in June, 1997, recorded a $10.0 million increase in loss and
LAE reserves during December, 1997, predominantly relating to 1995 and 1996
claims incurred prior to the Company's acquisition of AIC. This increase in
reserves was made to bring AIC's reserving practices consistent with the more
conservative method used by the Company's other insurance company operations.
Management
 
                                       33
<PAGE>
expects the increase in AIC's loss reserves to be adequate to cover any
subsequent adverse development of AIC's prior losses.
 
    Loss and LAE decreased $5.2 million in 1998, to $91.3 million, reflecting
the reduction in risk retention, despite the catastrophe loss in 1998 from the
Hurricanes Georges and Mitch. Excluding the effects of the catastrophe loss in
1998 and AIC's reserve strengthening in 1997, loss and LAE decreased $692,000
and the Company's GAAP loss ratio increased to 60.0% in 1998 from 53.2% in 1997.
Including these effects, the Company's GAAP loss ratio increased to 63.8% for
1998 from 59.4% in 1997. Both increases reflect the higher incurred losses and
LAE on substantially lower earned premium in 1998 when compared to 1997.
Additionally, the increased loss ratios reflect a general deterioration in
pricing in 1998 coupled with a higher frequency of attritional losses. The
Company's insurance company subsidiaries statutory combined ratio was 82.9% for
1998 compared to 78.8% for 1997. The Company's combined ratio remains
significantly better than the industry average.
 
    During 1998, the Company had net loss and LAE redundancy of $14.6 million
relating to prior year losses compared to a redundancy of $3.8 million in 1997.
During 1998, the Company had gross loss and LAE deficiency of $33.5 million
compared to a deficiency of $23.2 million in 1997. The gross deficiency results
from the development of several large claims on individual policies which were
either reported late or reserves were increased as subsequent information became
available. However, as most of these policies were substantially reinsured,
there is no material effect to the Company's net earnings. The redundancies in
the net reserves result from the Company's and its actuaries' continued review
of its loss reserves and the reduction of such reserves as losses are finally
settled and claims exposures are reduced. The Company continues to believe it
has materially provided for all net incurred losses.
 
    Compensation expense increased $4.6 million or 9% in 1998 to $56.1 million
due to the increase in personnel resulting from acquisitions completed during
1998, along with an increase in management personnel to oversee the operations
of the rapidly expanding group.
 
    Other operating expense increased 14% to $36.1 million in 1998. These
expenses reflect increased expenditures required to meet the overall growth in
business and from acquisitions. Currency conversion gains amounted to $219,000
in 1998, compared to losses of $884,000 in 1997.
 
    Merger expense represents non-recurring items incurred to consummate the
acquisitions and mergers which are accounted for as pooling-of-interests.
 
    Income tax expense was $35.2 million in 1998, compared to $23.3 million in
1997. The Company's effective tax rate was 32.8% in 1998 compared to 31.9% in
1997. As net income from the underwriting agency and intermediary operations
grow, the Company's effective tax rate increases due to state income taxes and
the mitigation of the effect of tax exempt municipal bond income on the combined
effective tax rate.
 
    Net earnings increased 45% to $72.3 million in 1998, from $49.8 million in
1997. Diluted earnings per share increased 44% to $1.48in 1998 from $1.03 in
1997.
 
YEAR ENDED DECEMBER 31, 1997 VERSUS YEAR ENDED DECEMBER 31, 1996
 
    Total revenue increased to $280.3 million in 1997 from $270.8 million in
1996. GWP increased to $346.4 million in 1997 from $337.3 million in 1996, due
primarily to increased aviation and accident and health premium offset by
decreased property and marine premium. NWP for 1997 decreased to $142.9 million
from $183.0 million in 1996, due to an increase in the amount of ceded
reinsurance. Net earned premium decreased to $162.6 million in 1997 compared to
$170.1 million in 1996 reflecting the reduction in NWP and the reduced
retentions of the Company.
 
    Management fees in 1997 increased 78% to $51.0 million from $28.7 million in
1996, reflecting internal growth and the acquisition of several underwriting
agencies in 1997. Commission income in 1997
 
                                       34
<PAGE>
increased 13% to $24.2 million from $21.5 million in 1996, reflecting internal
growth. Net investment income increased 17% to $27.6 million in 1997 from $23.6
million in 1996 reflecting a higher level of investment assets.
 
    Net realized investment losses from sales of equity securities were $154,000
during 1997, compared to gains of $8.3 million in 1996. During 1996, the Company
systematically liquidated the majority of its equity portfolio. Net realized
investment losses from disposition of fixed income securities were $174,000
during 1997, compared to gains of $29,000 in 1996.
 
    During 1996, the Company sold one of its subsidiaries. This sale generated
an after tax gain of $2.2 million or $0.05 per share and is included in other
operating income.
 
    Policy acquisitions costs, which are net of ceding commissions on
reinsurance ceded, increased $5.4 million or 65% between 1997 and 1996. The
increase reflects a higher average commission rate due to increase in the
accident and health line of business plus a $5.2 million ceded profit commission
in 1996 compared to $519,000 in 1997.
 
    AIC, acquired in June, 1997, recorded a $10.0 million increase in loss and
LAE reserves during December, 1997, predominately relating to 1995 and 1996
claims incurred prior to the Company's acquisition of AIC. This increase in
reserves was made to bring AIC's reserving practices consistent with the more
conservative method used by the Company's other insurance company operations.
Management expects the increase in AIC's loss reserves to be adequate to cover
any subsequent adverse development of AIC's prior losses.
 
    Loss and LAE decreased $18.0 million in 1997, to $96.5 million, reflecting
the increased use of reinsurance, despite the $10.0 million reserve
strengthening charge taken by AIC. During 1997, the Company had net loss and LAE
redundancy of $3.8 million relating to prior year losses compared to a
redundancy of $4.9 million in 1996. During 1997, the Company had gross loss and
LAE deficiency of $23.2 million compared to a deficiency of $42.5 million in
1996. The gross deficiency comes from two primary sources. Firstly, the
development of several large claims on individual policies which were either
reported late or reserves were increased as subsequent information became
available; however, as most of these policies were substantially reinsured,
there is no material effect to the Company's net earnings. Secondly, is the
run-off of the retrocessional excess of loss business which the Company
underwrote between 1988 and 1991. This development, $1.6 million in 1997
compared to $11.3 million in 1996, is primarily due to the delay in reporting of
catastrophe losses by the London insurance market, coupled with the
unprecedented number of catastrophes during the period in which the Company
underwrote this business. This business is also substantially reinsured, thereby
not having a material effect on the Company's net earnings.
 
    Compensation expense increased $9.4 million or 22% in 1997, to $51.5 million
due to the increase in personnel resulting from acquisitions completed during
1997, along with an increase in management personnel to oversee the operations
of the rapidly expanding group.
 
    Other operating expense increased 20% to $31.6 million in 1997. These
expenses reflect increased expenditures required to meet the overall growth in
business and from acquisitions. Currency conversion losses amounted to $884,000
in 1997, compared to losses of $181,000 in 1996.
 
    Merger expense represents non-recurring items incurred to consummate the
acquisitions and mergers which are accounted for as pooling-of-interests. The
amounts incurred during 1996 were due to the combination with LDG and included a
compensatory stock grant of $24.0 million to certain key LDG employees
immediately prior to the merger.
 
    Interest expense during 1997 increased 20% to $6.0 million from $5.0 million
during 1996 due to the increased level of indebtedness primarily to fund the
cash portion of acquisitions.
 
                                       35
<PAGE>
    Income tax expense was $23.3 million in 1997, compared to $9.9 million in
1996. The 1996 amount included a deferred tax benefit of $9.6 million which was
recorded in connection with the compensatory stock grant to certain key LDG
employees. The compensation expense was a non-cash item; however, $9.6 million
of actual cash tax savings will be recognized beginning from the grant date.
Most of the other merger expenses are not deductible for income tax purposes.
Also, as an S Corporation, LDG was exempt from Federal income taxes through May
21, 1996. Had LDG been subject to Federal income tax during the period January
1, 1996 to May 21, 1996, additional income tax expense of $2.3 million would
have been recorded in 1996.
 
    Net earnings increased 29% to $49.8 million in 1997 from $38.5 million in
1996. Diluted earnings per share increased 23% to $1.03 in 1997 from $0.84 in
1996.
 
    The Company's insurance company subsidiaries' statutory combined ratio was
78.8% for 1997 compared to 83.6% in 1996. The Company's combined ratio remains
significantly better than the industry average.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company receives substantial cash from premiums, reinsurance
recoverables, management fees and commission income and, to a lesser extent,
investment income, and proceeds from sales and redemptions of investment assets.
The principal cash outflows are for the payment of claims and LAE, payment of
premiums to reinsurers, purchase of investments, debt service, policy
acquisition costs, operating expenses, income and other taxes and dividends.
 
    At December 31, 1998, several of the Company's subsidiaries maintained
revolving lines of credit with a bank in the combined maximum amount of $40.0
million available through December 30, 1999. Advances under the lines of credit
are primarily used to fund draws, if any, on letters of credit issued by the
bank on behalf of the subsidiaries. The lines of credit are collateralized by
securities having an aggregate market value of up to $50.0 million, the actual
amount of collateral at any one time being 125% of the aggregate amount
outstanding. Interest on the lines is payable at the bank's prime rate of
interest (7.75% at December 31, 1998). At December 31, 1998, letters of credit
totaling $19.8 million had been issued to insurance companies by the bank on
behalf of the subsidiaries, with total securities collateralizing the line of
$24.8 million.
 
    On March 8, 1999, the Company entered into a Loan Agreement (the "Facility")
with a group of banks. The Facility includes a $150.0 million Revolving Loan
Facility and $100.0 million Short Term Revolving Loan Facility. Borrowing under
the Facility may be made from time to time by the Company for general corporate
purposes through the Short Term Revolving Loan Facility until its expiration on
March 7, 2000 and through the Revolving Loan Facility until its expiration on
February 28, 2002. Outstanding loans under the Facility bear interest at agreed
upon rates. The Facility is collateralized in part by the pledge of the stock of
HC, AIC, and USSIC and by the pledge of stock and guaranties entered into by the
Company's principal underwriting agency and intermediary subsidiaries. The
Facility agreement contains certain restrictive covenants, including, without
limitation, minimum net worth requirements for the Company and certain
subsidiaries, restrictions on certain extraordinary corporate actions, notice
requirements for certain material occurrences, and required maintenance of
specified financial ratios. Management believes that the restrictive covenants
and other obligations of the Company which are contained in the Facility
agreement are typical for financing arrangements comparable to the Facility. The
initial funding available under the Facility was used, among other things, to
refinance existing indebtedness of the Company including all outstanding
indebtedness under the Company's $120.0 million revolving credit facility
entered into as of December 30, 1997, which has been terminated.
 
    As of March 13, 1999, total debt outstanding under the Facility was $176.0
million with $150.0 million due under the $150.0 million Revolving Loan Facility
and $26.0 million due under the $100.0 million Short
 
                                       36
<PAGE>
Term Revolving Loan Facility. The increase in debt subsequent to December 31,
1998 resulted from the funding of the purchase price of acquisitions.
 
    The Company maintains a substantial level of cash and liquid short-term
investments which are used to meet anticipated payment obligations. As of
December 31, 1998, the Company had cash and short-term investments of
approximately $145.1 million. The Company's consolidated investment portfolio of
$525.6 million as of December 31, 1998 (of which $129.1 million is short-term
investments), is available to provide additional liquidity and cash for
operations.
 
    Property and casualty insurance companies domiciled in the State of Texas
are limited in the payment of dividends to their shareholders in any 12 month
period, without the prior written consent of the Commissioner of Insurance, to
the greater of statutory net income or 10% of statutory policyholders' surplus.
HC paid no dividends to HCC in 1998. During 1999, HC's ordinary dividend
capacity will be approximately $38.2 million.
 
    Under the laws of the State of Maryland, AIC may only pay dividends out of
statutory earned surplus. The maximum amount of dividends that AIC may pay
without prior regulatory approval in any 12 month period is the greater of its
statutory net income (under certain conditions) or 10% of its statutory
policyholders' surplus. The maximum amount at December 31, 1998 was $10.5
million.
 
    The Company believes that its operating cash flows, short-term investments
and the Facility will provide sufficient sources of liquidity to meet its
anticipated needs for the foreseeable future.
 
    At December 31, 1998, the Company had a net deferred tax asset of $3.4
million compared to $6.6 million at December 31, 1997. Due to the Company's
history of consistent earnings and expectations for the future, it is more
likely than not that the Company will be able to realize the benefit of its
deferred tax asset.
 
    The overall increase in activities at the insurance company subsidiaries
resulted in increases in gross loss reserves, gross unearned premiums, deferred
policy acquisition costs and deferred ceding commissions since December 31,
1997. The Company continues to collect its receivables and recoverables
generally in the ordinary course and has not incurred and does not expect to
incur any significant liquidity difficulties as a result of the substantial
growth in gross amounts due. The Company limits any liquidity exposure it may
have by holding funds, letters of credit or other security such that net
balances due to it are significantly less than the gross balances shown in the
consolidated balance sheet.
 
    As of December 31, 1998, each of the domestic insurance company
subsidiaries' total adjusted capital is significantly in excess of the NAIC
authorized control level risk-based capital.
 
    Industry and regulatory guidelines suggest that a property and casualty
insurer's annual statutory GWP should not exceed 900% of its statutory
policyholders' surplus and NWP should not exceed 300% of its statutory
policyholders' surplus. The Company's insurance company subsidiaries maintain a
premium to surplus ratio significantly lower than such guidelines, and for the
year ended December 31, 1998, their annual statutory GWP was 135.6% of their
statutory policyholders' surplus and their NWP was 33.4% of their statutory
policyholders' surplus.
 
IMPACT OF INFLATION
 
    The Company's operations, like those of other property and casualty
insurers, are susceptible to the effects of inflation, as premiums are
established before the ultimate amounts of loss and LAE are known. Although
management considers the potential effects of inflation when setting premium
rates, for competitive reasons, such premiums may not adequately compensate the
Company for the effects of inflation. However, as the majority of the Company's
business is comprised of lines which have short lead times between the
occurrence of an insured event, reporting of the claims to the Company and the
final settlement of the claims, the effects of inflation are minimized.
 
                                       37
<PAGE>
    A significant portion of the Company's revenue is related to healthcare
insurance and reinsurance products which are subject to the effects of the
underlying inflation of medical costs. Such inflation in the costs of healthcare
tends to generate increases in premiums for medical stop-loss coverage,
resulting in greater revenue, but also higher claim payments. Inflation may have
a negative impact on insurance and reinsurance operations by causing higher
claim settlements than may originally have been estimated without an immediate
increase in premiums to a level necessary to maintain profit margins. No express
provision for inflation is made, although trends are considered when setting
underwriting terms and claim reserves. Claim reserves are subject to a
continuing review process to assess their adequacy and are adjusted as deemed
appropriate. In addition, the market value of the investments held by the
Company varies depending on economic and market conditions and interest rates,
which are highly sensitive to the policies of governmental and regulatory
authorities. Any significant increase in interest rates could therefore have a
material adverse effect on the market value of the Company's investments. In
addition, the Company's $250.0 million Facility's interest rate floats with that
of the market. Any significant increase in interest rates could result in
increased interest costs under the Facility, which could have a material adverse
effect on earnings.
 
EXCHANGE RATE FLUCTUATIONS
 
    The Company underwrites risks which are denominated in a number of foreign
currencies. It establishes and maintains loss reserves with respect to these
policies in their respective currencies. These reserves are subject to exchange
rate fluctuations which can have an effect on the Company's net earnings. The
Company's principal area of exposure is with respect to fluctuation in the
exchange rate between the major European currencies and the United States
Dollar. For the years ended December 31, 1998, 1997 and 1996, the gain (loss)
from currency conversion was $219,000, ($884,000) and ($181,000), respectively.
 
    The Company's balances denominated in foreign currencies fluctuate as
transactions are recorded and settled. From time to time the Company has entered
into foreign currency forward contracts as a hedge against foreign currency
fluctuations. Such activity has been on a very limited basis in the past. The
Company did not hedge this risk in 1998 and there were no open foreign currency
forward contracts as of December 31, 1998. In the future, the Company may limit
its exposure to currency fluctuations through the use of foreign currency
forward contracts. The Company utilizes these foreign currency forward contracts
strictly as a hedge against existing exposure to foreign currency fluctuations
rather than as a form of speculative or trading investment.
 
EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS
 
    The Company adopted Statement of Financial Accounting Standards (SFAS") No.
130 entitled "Reporting Comprehensive Income" in 1998. This statement required
that all components of comprehensive income be reported in a full set of
financial statements and that the amount of total comprehensive income be
reported. Other comprehensive income includes gains and losses that are excluded
from net income, but are added to or deducted from net earnings in order to
calculate comprehensive income. Unrealized investment gains and losses of
investments and net unrealized gains and losses on foreign currency translation
are examples of such items.
 
    The Company also adopted SFAS No. 131 entitled "Disclosures about Segments
of an Enterprise and Related Information" in 1998. This statement changed the
way the Company reports information about its operating segments. The agency
segment from prior years is now split into the underwriting agency and
intermediary segments. The corporate and other segment from prior years is now
split into two segments, other operations and corporate. Adoption of SFAS No.
131 had no effect on the Company's consolidated financial position, results of
operations or shareholders' equity.
 
    SFAS No. 133 entitled "Accounting for Derivative Instruments and Hedging
Activities" was issued in June, 1998. The statement is effective for all fiscal
quarters and years beginning after June 15, 1999. The
 
                                       38
<PAGE>
Company has utilized derivatives or hedging strategies only infrequently in the
past and in immaterial amounts, although it may do so more frequently in the
future as it expands its foreign operations. The Company is not a party to any
derivatives or hedging activities at December 31, 1998. The effect of the
Statement as well as the timing of its adoption are currently being reviewed by
management.
 
    In December, 1997, the American Institute of Certified Public Accountants'
Accounting Executives Standards Committee ("AcSEC") issued Statement of Position
("SOP") 97-3, "Accounting by Insurance and Other Enterprises for
Insurance-Related Assessments," which provides guidance on accounting by all
entities that are subject to insurance-related assessments. It requires that
entities should recognize liabilities for insurance-related assessments when
certain specified criteria have been met. This SOP is effective for financial
statements for fiscal years beginning after December 15, 1998. The Company does
not expect the adoption of this SOP to have a material effect on the Company's
financial position, results of operations or shareholders' equity.
 
    In November, 1998, AcSEC issued SOP 98-7, "Deposit Accounting: Accounting
for Insurance and Reinsurance Contracts That Do Not Transfer Insurance Risk."
The SOP provides guidance as to the use of deposit accounting for insurance and
reinsurance contracts that do not transfer insurance risk. This SOP is effective
for financial statements for fiscal years beginning after June 15, 1999. The
Company does not expect the adoption of this SOP to have a material effect on
the Company's financial position, results of operations or shareholders' equity.
 
YEAR 2000
 
    The Year 2000 issue is the result of date coding within computer programs
that were written using just two digits rather than four digits to define the
applicable year. If not corrected, these date codes could cause computers to
fail to calculate dates beyond 1999 and, as a result, computer applications
could fail or create erroneous results by or at the Year 2000.
 
    The Company, together with outside vendors engaged by the Company, has made
assessments of the Company's potential Year 2000 exposure related to its
computerized information systems and is currently engaged in efforts to
remediate and test these systems for potential Year 2000 exposures. The Company
has also made assessments of the potential Year 2000 exposure associated with
its embedded technology systems, such as telephone systems, environmental
control systems and elevators, and does not believe that it has significant Year
2000 exposure in this area.
 
    The Company is currently involved in discussion with important suppliers,
business partners, customers and other third parties to determine the extent to
which the Company may be vulnerable to the failure of these parties to identify
and correct their own Year 2000 issues. Based upon information received from
these third parties, management does not believe that the Company has any
significant Year 2000 exposures related to its third party relationships.
 
    In addition to its own systems and third-party relationships, the Company
may also have exposure in the property and casualty operations of its insurance
company subsidiaries to claims asserted under certain insurance policies for
damages caused by an insured's failure to address its own Year 2000 computer
problems. Together with other companies in the insurance industry, the Company
has and continues to evaluate the potential insurance exposures arising from
Year 2000 problems or responses. The Company's insurance company subsidiaries do
not generally offer policies of insurance marketed as Year 2000 liability
coverage. However, due to the nature of certain of the policies, such as
policies of property insurance, insureds may attempt to submit claims for
coverage under such policies which may be result from Year 2000 related causes.
In this regard, the Company is currently assessing what modifications or
responses may be appropriate related to the insurance coverages currently
offered by such subsidiaries in light of coverage issues associated with the
Year 2000 problem. Due to the difficulty in accurately assessing potential Year
2000 losses, if any, related to Year 2000 coverage issues, it is not possible to
reasonably estimate their potential effects on the Company's financial position
and results of operations.
 
                                       39
<PAGE>
    The Company's own software vendor subsidiary has completed its Year 2000
compliance plan, and, based upon the results, management believes that the
subsidiary's products are Year 2000 compliant.
 
    The Company is utilizing and will continue to utilize both internal and
external resources to evaluate and mitigate its Year 2000 exposures in advance
of respective critical dates. Further, in the ongoing acquisition of technology
and business equipment, the Company generally requires that its vendors certify
the Year 2000 compliance of acquired products. The Company relies upon such
certifications.
 
    During the two years ended December 31, 1998, the Company expensed $546,000
with respect to Year 2000 compliance and capitalized $6 million with respect to
new software purchases and installations which are Year 2000 compliant. The
total estimated remaining cost of modification of existing software and new Year
2000 compliant systems is $1.5 million which includes $1.2 million attributable
to the planned purchase and implementation of new systems. The cost of this new
software is being capitalized. The remaining estimated cost of $230,000 will be
expensed as incurred over the next twelve months. The Company does not track
internal costs with respect to the expenses related to Year 2000 remediation.
The level of expense anticipated in connection with the Year 2000 issues is not
expected to have a material effect on the Company's results of operations. The
costs of the Company's Year 2000 compliance efforts are expected to be funded
out of operating cash flow, which is sufficient to provide funding. To date, no
material information technology projects of the Company have been delayed as a
result of the Company's Year 2000 compliance efforts.
 
    The Company believes that its Year 2000 compliance plan will be successful
based upon its progress to date. Many of the Company's major systems have been
replaced or remediated, where necessary, including that of a major insurance
company subsidiary, and are currently successfully processing business and
information that contain the Year 2000 or later years. No new information has
come to management's attention that would indicate that the plan should be
altered significantly or that the plan will not be successful in the time frame
prescribed by the plan. Nevertheless, the Company is in the process of
developing a contingency plan for the remote possibility that there could be an
unforeseen Year 2000 failure. Such plan will develop and document procedures to
address any material Year 2000 failures until remediation of the related systems
could be performed.
 
    The dates of expected completion and the costs of the Company's Year 2000
remediation efforts are based on management's estimates, which were derived
utilizing assumptions of future events, including the availability of certain
resources, third party remediation plans and other factors. There can be no
guarantee that these estimates will be achieved, and if the actual timing and
costs for the Company's Year 2000 remediation program differ materially from
those anticipated, the Company's financial results and financial condition could
be significantly affected. Additionally, despite testing by the Company, the
Company's systems may contain undetected errors or defects associated with Year
2000 date functions. The inability of the Company to correctly identify
significant Year 2000 issues for remediation or to complete its Year 2000
remediation and testing efforts prior to respective critical dates, the failure
of its contingency planning, the failure of third parties with whom the Company
has an important relationship to identify, remediate and test their own Year
2000 issues and the resulting disruption which could occur in the Company's
systems, the impact of future acquisitions in which Year 2000 issues in the
acquired systems have not been remediated or tested and the inability of the
Company to adequately address coverage issues related to its insurance company
subsidiaries, could have material adverse effects on the Company's business,
results of operations, cash flows and financial condition.
 
EURO CONVERSION
 
    On January 1, 1999, certain member countries of the European Union
irrevocably fixed the conversion rates between their national currencies and a
common currency, the "Euro", which became their common legal currency on that
date. The participating countries' former national currencies will continue to
serve as legal tender and denominations of the Euro between January 1, 1999 and
January 1, 2002. The
 
                                       40
<PAGE>
conversion to the Euro is scheduled to be completed on July 1, 2002, when the
national currencies will cease to exist. The Company does not expect the
introduction of the Euro to have a material effect on the Company's business,
software plans, financial condition or results of operations.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
    The Company's principal assets and liabilities are financial instruments
which are subject to the market risk of potential losses from adverse changes in
market rates and prices. The Company's primary market risk exposures are:
interest rate risk on fixed income securities and interest expense on variable
rate debt, equity risk on marketable equity securities, credit risk on its
reinsurance recoverables and foreign currency exchange risk.
 
    To manage its exposures of investment risks, the Company generally invests
in investment grade securities with characteristics of duration and liquidity to
reflect the underlying characteristics of its insurance liabilities. The Company
does not use derivatives to manage any of its investment related market risks.
 
    Caution should be used in evaluating overall market risk from the
information below. Actual results could differ materially from estimates below
for a variety of reasons, including (but not limited to):
 
    - Market changes could be different from market changes assumed below,
 
    - Amounts and balances on which the estimates are based are likely to change
      over time,
 
    - Not all factors and balances are taken into account, and
 
    - Assumptions used in the models may prove to be inaccurate.
 
INTEREST RATE RISK
 
    The Company's portfolio of fixed income securities is inversely correlated
to changes in the market interest rates. In addition, some of the companies
fixed income securities have call or prepayment options, which could subject the
Company to reinvestment risk. Should interest rates fall, issuers call their
securities, and the Company reinvests the proceeds at lower interest rates. The
fair value of the Company's fixed income securities as of December 31, 1998 was
$393.2 million. If interest rates were to change 1%, the fair value of the
Company's fixed income securities would change approximately $21.9 million. The
change in fair value was determined using duration modeling assuming no
prepayments.
 
    The Facility entered into by the Company is subject to variable interest
rates. Thus, the Company's interest expense is directly correlated to market
interest rates. As of March 31, 1999, the Company had $176.0 million in debt
outstanding. At this debt level, a 1% change in market interest rates would
change the Company's interest expense by $1.8 million.
 
EQUITY RISK
 
    The Company's portfolio of marketable equity securities is subject to equity
price risk due to market changes. The fair value of the Company's marketable
equity securities (including those designated as strategic operational
investments) as of December 31, 1998 was $18.2 million. If the market price of
all marketable equity securities were to change by 10%, the fair value of the
Company's equity portfolio would change $1.8 million.
 
CREDIT RISK
 
    See Reinsurance Ceded section contained in Item 1., Business, and Footnote
(8) in the Notes to Consolidated Financial Statements.
 
FOREIGN EXCHANGE RISK
 
    The Company underwrites risks which are denominated in a number of foreign
currencies. It establishes and maintains loss reserves with respect to these
policies in their respective currencies, as well as having varying receivable
and payable balances at any point in time. These amounts are subject to
 
                                       42
<PAGE>
exchange rate fluctuations which can have an effect on the Company's net
earnings. The Company's principal area of exposure is with respect to
fluctuation in the exchange rate between the major European currencies and the
United Sates Dollar.
 
    The table below shows the net amounts of significant foreign currency
balances at December 31, 1998 converted to US Dollars. It also shows the
expected dollar change in fair value that would occur if exchange rates changed
10% from December 31, 1998 exchange rates.

</TABLE>
 
    On a historical basis, the eleven national currencies which are now in the
process of being converted to the Euro have not always had their relative
exchange rates change together. However, with the fixing of exchange rates on
January 1, 1999, relative to the new Euro, these currencies will now behave as
one currency.
 
    From time to time the Company enters into foreign currency forward contracts
as a hedge against foreign currency fluctuations. The Company did not hedge this
risk in 1998 and there were no open foreign currency forward contracts as of
December 31, 1998. In the future, the Company may limit its exposure to currency
fluctuations through the use of foreign currency forward contracts. The Company
utilizes these foreign currency forward contracts strictly as a hedge against
existing exposure to foreign currency fluctuations rather than as a form of
speculative or trading investment.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
HCC Insurance Holdings, Inc.
 
In our opinion, based on our audits and the report of the other auditors, the
accompanying consolidated balance sheets and the related consolidated statements
of earnings, comprehensive income, changes in shareholders' equity and cash
flows present fairly, in all material respects, the financial position of HCC
Insurance Holdings, Inc. and its subsidiaries at December 31, 1998 and 1997, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1998, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
HCC Insurance Holding Inc.'s management; our responsibility is to express an
opinion on these financial statements based on our audits. We did not audit the
1996 consolidated financial statements of Avemco Corporation, which statements
reflect total revenues constituting 43.7 percent and net earnings constituting
24.0 percent of the related consolidated financial statement totals for the year
ended December 31, 1996. Those statements were audited by other auditors whose
report dated January 31, 1997 except for Note 12, of which the date is February
28, 1997 and except for Note 14, of which the date is February 18, 1998, has
been furnished to us, and our opinion, insofar as it relates to data included
for 1996 is based solely on the report of the other auditors. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits and the report of the other auditors provide a reasonable basis for the
opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
 
    HCC Insurance Holdings, Inc. and its subsidiaries (collectively, "the
Company" or "HCC"), include domestic and foreign property and casualty insurance
companies, underwriting agencies, intermediaries and service companies. HCC,
through its subsidiaries, provides specialized property and casualty insurance
primarily to commercial customers worldwide, underwritten on both a direct and
reinsurance basis, in the aviation, marine, property, offshore energy, medical
stop-loss, accident and health, workers' compensation and lenders' single
interest lines of business. The principal insurance company subsidiaries are
Houston Casualty Company ("HC") in Houston, Texas, London, England and Amman,
Jordan; U.S. Specialty Insurance Company ("USSIC") in Houston, Texas; and Avemco
Insurance Company ("AIC") in Frederick, Maryland. The underwriting agency
subsidiaries provide underwriting management and claims servicing for insurance
and reinsurance companies, primarily in the medical stop-loss, accident and
health, workers' compensation and aviation lines of business. The principal
agency subsidiaries are LDG Reinsurance Corporation ("LDG Re") in Wakefield,
Massachusetts; HCC Aviation Insurance Group, Inc. ("HCCA") in Dallas, Texas and
Glendale, California; HCC Employer Services, Inc. ("HCCES") in Northbrook,
Illinois, Dallas, Texas and Montgomery, Alabama; and HCC Benefits Corporation
("HCCB") in Atlanta, Georgia, Wakefield, Massachusetts, Minneapolis, Minnesota
and Kansas City, Kansas. The intermediary subsidiaries provide brokerage,
consulting and other intermediary services to insurance and reinsurance
companies, commercial customers and individuals in the same lines of business as
the insurance company subsidiaries operate. The Company's principal intermediary
subsidiaries are HCC Intermediaries, Inc. ("HCCI") in Houston, Texas; HCC
Employee Benefits, Inc. ("HCCEB") in Houston, Texas; and Rattner Mackenzie
Limited ("RML") in London, England and Amman, Jordan. The service company
subsidiaries perform various insurance related services for insurance companies.
 
    The preparation of financial statements in conformity with generally
accepted accounting principles ("GAAP") requires management to make estimates
and assumptions. This affects amounts reported in the financial statements and
the disclosure of contingent assets and liabilities. Actual results could differ
from those estimates.
 
    A description of the significant accounting and reporting policies utilized
by the Company in preparing the consolidated financial statements is as follows:
 
PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany balances and
transactions have been eliminated in consolidation. During February 1998, the
Company acquired all of the outstanding common stock of The Kachler Corporation
("Kachler") in a transaction accounted for as a pooling-of-interests. (See Note
2) The Company's financial statements have been restated to include the accounts
and operations of Kachler for all periods presented.
 
INVESTMENTS
 
    Fixed income securities and marketable equity securities are classified as
available for sale and are carried at quoted market value, if readily
marketable, or at management's estimated fair value, if not readily marketable.
The change in unrealized gain or loss with respect to these securities is
recorded as a component of other comprehensive income, net of related deferred
income tax, if any. Fixed income securities available for sale are purchased
with the original intent to hold to maturity, but they may be available for sale
if market conditions warrant, or if the Company's investment policies dictate,
in order to

(CONTINUED)
maximize the Company's investment yield. Short-term investments and restricted
short-term investments are carried at cost, which approximates market value.
 
    The realized gain or loss on investment transactions is determined on an
average cost basis and included in earnings on the trade date. When impairment
of the value of an investment is considered other than temporary, the decrease
in value is reported in earnings as a realized investment loss and a new cost
basis is established.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are carried at cost, net of accumulated depreciation.
Depreciation expense is provided using the straight-line method over the
estimated useful lives of the related assets. Amortization of leasehold
improvements is provided using the straight-line method over the term of the
respective lease. Upon disposal of assets, the cost and related accumulated
depreciation are removed from the accounts and the resulting gain or loss is
included in earnings.
 
    Costs incurred in developing or purchasing management information systems
are capitalized and included in property and equipment. These costs are
amortized over their estimated useful lives from the dates the systems are
placed in service.
 
EARNED PREMIUM, DEFERRED POLICY ACQUISITION COSTS AND CEDING COMMISSIONS OF
  INSURANCE COMPANY SUBSIDIARIES
 
    Written premium, net of reinsurance, is primarily included in earnings on a
pro rata basis over the lives of the related policies. However, for certain
types of business, it is recognized over the period of risk in proportion to the
amount of insurance risk provided. Policy acquisition costs, including
commissions, taxes, fees and other direct costs of underwriting policies, less
ceding commissions allowed by reinsurers, including expense allowances, are
deferred and charged or credited to earnings proportionate to the premium
earned. Historical and current loss and loss adjustment expense experience and
anticipated investment income are considered in determining the recoverability
of deferred policy acquisition costs.
 
MANAGEMENT FEES AND COMMISSION INCOME
 
    Management fees and commission income are recognized on the revenue
recognition date, which is the later of the effective date of the policy, the
date when the premium can be reasonably estimated, or the date when
substantially all required services relating to the insurance placement have
been rendered to the client. Management fees and commission income relating to
additional or return premiums or other policy adjustments are recognized when
the events occur and the amounts become known or can be estimated.
 
PREMIUM AND OTHER RECEIVABLES
 
    The Company has adopted the gross method for reporting receivables and
payables on brokered transactions. Management reviews the collectibility of its
receivables on a current basis and provides an allowance for doubtful accounts
if it deems that there are accounts which are doubtful of collection. The amount
of the allowance at December 31, 1998 and 1997, is not material.

(1) GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
(CONTINUED)
LOSS AND LOSS ADJUSTMENT EXPENSE PAYABLE OF INSURANCE COMPANY SUBSIDIARIES
 
    Loss and loss adjustment expense payable is based on undiscounted estimates
of payments to be made for reported and incurred but not reported ("IBNR")
losses and anticipated salvage and subrogation receipts. Estimates for reported
losses are based on all available information, including reports received from
ceding companies on assumed business. Estimates for IBNR are based both on the
Company's and the industry's experience. While management believes that amounts
included in the accompanying financial statements are adequate, such estimates
may be more or less than the amounts ultimately paid when the claims are
settled. The estimates are continually reviewed and any changes are reflected in
current operations.
 
REINSURANCE
 
    The Company records all reinsurance recoverables and ceded unearned premiums
as assets and deferred ceding commissions as a liability. All such amounts are
estimated and recorded in a manner consistent with the underlying reinsured
contracts. Management has recorded a reserve for uncollectible reinsurance based
on estimates of collectibility.   The adverse economic environment in the
insurance industry has placed great pressure on reinsurers and the results of
their operations. These conditions could, ultimately, affect reinsurers'
solvency. Historically, there have been insolvencies following a period of
competitive pricing in the industry, such as the marketplace is experiencing
today. Therefore, while management believes that the reserve is adequate,
conditions can change or additional information might be obtained that would
affect management's estimate of the adequacy of the level of the reserve and
which may result in a future increase or decrease in the reserve.
 
GOODWILL
 
    In connection with the Company's acquisitions of subsidiaries accounted for
as purchases, the excess of cost over fair value of net assets acquired is being
amortized using the straight-line method over twenty years for acquired
underwriting agency and intermediary operations which operate in existing lines
of business and in the same country as existing operations. Goodwill related to
such acquired operations which represent the Company's initial entry into new
lines of business or new countries is amortized over thirty years. Goodwill
related to acquired insurance company operations is amortized over forty years.
Managements of the acquired businesses have successfully operated in their
markets for a number of years and, with the additional capital provided by the
Company, will be positioned to take advantage of increased opportunities.
Accumulated amortization of goodwill as of December 31, 1998 and 1997, was $5.2
million and $2.8 million, respectively.
 
    The Company has no reason to expect major changes in the business conditions
in which the acquired companies operate which might affect the recoverability of
the recorded goodwill. However, in the event business conditions change, the
recoverability will be re-evaluated based upon revised projections of future
undiscounted operating income and cash flows and, if impaired, the balances will
be adjusted accordingly. Amortization of goodwill charged to income for the
years ended December 31, 1998, 1997 and 1996, was $3.0 million, $1.6 million and
$684,000, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
(1) GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
(CONTINUED)
CASH AND SHORT-TERM INVESTMENTS
 
    Cash consists of cash in banks, generally in operating accounts. The Company
classifies certificates of deposit, corporate demand notes receivable,
commercial paper and money market funds as short-term investments. Short-term
investments are classified as investments in the consolidated balance sheets as
they relate principally to the Company's investment activities.
 
    The Company generally maintains its cash deposits in major banks and invests
its short-term investments with major banks and in investment grade commercial
paper and repurchase agreements. These securities typically mature within 90
days and, therefore, bear minimal risk. The Company has not experienced any
losses on its cash deposits or its short-term investments.
 
RESTRICTED CASH AND CASH INVESTMENTS
 
    In conjunction with the management of reinsurance pools, the Company's
agency subsidiaries withhold premium funds for the payment of claims. These
funds are shown as restricted cash and cash investments in the consolidated
balance sheets. The corresponding liability is included within premium and
claims payable in the consolidated balance sheets. These amounts are considered
fiduciary funds, and interest earned on these funds accrues to the benefit of
the members of the reinsurance pools. Therefore, the Company does not include
these amounts as cash in the consolidated statements of cash flows.
 
FOREIGN CURRENCY TRANSLATION
 
    The functional currency of most foreign subsidiaries and branches is the
United States dollar. Assets and liabilities recorded in foreign currencies are
translated into United States dollars at exchange rates in effect at the balance
sheet date. Transactions in foreign currencies are translated at the rates of
exchange in effect on the date the transaction occurs. Translation gains and
losses are recorded in earnings and included in other operating expenses. The
Company's foreign currency transactions are principally denominated in British
Pound Sterling ("GBP") and other European currencies. From time to time the
Company enters into foreign currency forward contracts as a hedge against
foreign currency fluctuations. Gains or losses in the market value of foreign
currency forward contracts are recognized in the statements of earnings
concurrently with the gains and losses on the hedged balances. For the years
ended December 31, 1998, 1997 and 1996, the gain (loss) from currency conversion
was $219,000, ($884,000) and ($181,000), respectively.
 
    Some foreign subsidiaries or branches have a functional currency of either
the GBP or the Canadian Dollar ("CAD"). The cumulative translation adjustment,
representing the effect of translating these subsidiaries' or branches' assets
and liabilities into United States dollars, is included in the foreign currency
translation adjustment within accumulated other comprehensive income.
 
COMPUTER PRODUCTS AND SERVICES
 
    Revenue from custom software products is recognized using the percentage of
completion method of accounting. Revenue from other software contracts is
recognized when delivery has occurred, other remaining vendor obligations are no
longer significant, and collectibility is probable. Revenue from the sale of
computer hardware is recognized when delivery has occurred. Maintenance support
is recognized

(CONTINUED)
pro rata over the term of the maintenance agreement. Revenue from such products
and services is included in other operating income.
 
    Software production costs are capitalized when the technological feasibility
of a new product has been established. The capitalized costs are amortized based
upon current and future revenue for each product with a minimum of straight-line
amortization over the remaining estimated economic life of the product. All
other software development costs are expenses as incurred.
 
INCOME TAX
 
    The companies file a consolidated Federal income tax return and include the
foreign subsidiaries' income to the extent required by law. Deferred income tax
is accounted for using the liability method, which reflects the tax impact of
temporary differences between the bases of assets and liabilities for financial
reporting purposes and such bases as measured by tax laws and regulations. A
company acquired in a pooling-of-interests transaction was an S Corporation
prior to the pooling. Therefore, Federal income tax expense was not provided for
that company's earnings until the S Corporation election was terminated on May
22, 1996.
 
EARNINGS PER SHARE
 
    Basic earnings per share are based on the weighted average number of common
shares outstanding during the year divided into net earnings. Diluted earnings
per share are based on the weighted average number of common shares outstanding
plus the potential common shares outstanding during the year divided into net
earnings. Outstanding common stock options, when dilutive, are considered to be
potential common stock for the purpose of the diluted calculation. The treasury
stock method is used to calculate potential common stock outstanding due to
options. Contingent shares to be issued are included in the diluted earnings per
share computation only when the underlying conditions for issuance have been
met.
 
COMPREHENSIVE INCOME
 
    The Company adopted Statement of Financial Accounting Standards ("SFAS") No.
130 entitled "Reporting Comprehensive Income" in 1998. This statement required
that all components of comprehensive income be reported in a full set of
financial statements and that the amount of total comprehensive income be
reported. Other comprehensive income includes gains and losses that are excluded
from net income, but are added to or deducted from net earnings in order to
calculate comprehensive income. Unrealized investment gains and losses of
investments and net unrealized gains and losses on foreign currency translation
are examples of such items.
 
SEGMENT REPORTING
 
    The Company also adopted SFAS No. 131 entitled "Disclosures about Segments
of an Enterprise and Related Information" in 1998. This statement changed the
way the Company reports information about its operating segments. The agency
segment from prior years is now split into the underwriting agency and
intermediary segments. The corporate and other segment from prior years is now
split into two segments,

(CONTINUED)
other operations and corporate. Adoption of SFAS No. 131 had no effect on the
Company's consolidated financial position, results of operations or
shareholders' equity.
 
EFFECTS OF RECENT ACCOUNTING PRONOUNCEMENTS
 
    SFAS No. 133 entitled "Accounting for Derivative Instruments and Hedging
Activities" was issued in June, 1998. The statement is effective for all fiscal
quarters and years beginning after June 15, 1999. The Company has utilized
derivatives or hedging strategies only infrequently in the past and in
immaterial amounts, although it may do so more frequently in the future as it
expands its foreign operations. The Company is not a party to any derivatives or
hedging activities at December 31, 1998. The effect of the Statement as well as
the timing of its adoption are currently being reviewed by management.
 
    In December, 1997, the American Institute of Certified Public Accountants'
Accounting Executives Standards Committee ("AcSEC") issued Statement of Position
("SOP") 97-3, "Accounting by Insurance and Other Enterprises for
Insurance-Related Assessments," which provides guidance on accounting by all
entities that are subject to insurance-related assessments. It required that
entities should recognize liabilities for insurance-related assessments when
certain specified criteria have been met. This SOP is effective for financial
statements for fiscal years beginning after December 15, 1998. The Company does
not expect the adoption of this SOP to have a material effect on the Company's
financial position, results of operations or shareholders' equity.
 
    In November, 1998, AcSEC issued SOP 98-7, "Deposit Accounting: Accounting
for Insurance and Reinsurance Contracts That Do Not Transfer Insurance Risk"
which provides guidance as to the use of deposit accounting for insurance and
reinsurance contracts that do not transfer insurance risk. This SOP is effective
for financial statements for fiscal year beginning after June 15, 1999. The
Company does not expect the adoption of this SOP to have a material effect on
the Company's financial position, results of operations or shareholders' equity.
 
RECLASSIFICATIONS
 
    Certain amounts in the 1997 and 1996 consolidated financial statements and
the quarterly financial data (See Note 18) have been reclassified to conform
with the 1998 presentation and to reflect application of SFAS No. 130 and SFAS
No. 131. Such reclassifications had no effect on the Company's shareholders'
equity, net earnings or cash flows.
 
(2) ACQUISITIONS AND DISPOSITIONS
 
ACQUISITIONS
 
    On February 27, 1998, the Company acquired all of the outstanding common
stock of The Kachler Corporation ("Kachler") in exchange for 1,600,000 shares of
the Company's common stock. The acquisition was accounted for as a
pooling-of-interests and, accordingly, the Company's consolidated financial
statements have been restated to reflect the combination. Total revenue and net
earnings of Kachler prior to the acquisition are immaterial in relation to the
Company's revenue and net earnings.
 
    During 1998 the Company acquired four underwriting agency operations in
transactions accounted for under the purchase method of accounting. The total
consideration paid was 287,025 shares of the

Company's Common Stock and $48.2 million in cash. On a combined basis, the fair
value of assets acquired was $44.9 million and the fair value of liabilities
assumed was $46.2 million. Goodwill in the aggregate amount of $55.9 million was
recorded in connection with these transactions. The goodwill is being amortized
over periods of twenty to thirty years.
 
    The results of operations of the businesses acquired in purchase
transactions have been included in the consolidated financial statements
beginning on the effective date of each transaction.
 
    In connection with one of the acquisitions, the Company will also issue up
to 378,000 shares of its common stock on a contingent basis assuming certain
future financial benchmarks are met. Contingent shares issued will be recorded
as additional consideration at the current fair value if and when the financial
benchmarks are met.
 
    The following unaudited proforma summary presents information as if the 1998
purchase acquisitions had occurred at the beginning of each year after giving
effect to certain adjustments including amortization of goodwill, increased
interest expense from debt issued to fund the acquisitions and Federal income
taxes. The proforma summary is for information purposes only, does not
necessarily reflect the actual results that would have occurred, nor is it
necessarily indicative of future results of the combined companies. The
unaudited proforma summary information for companies acquired in 1997 in
purchase transactions is not presented due to immateriality.

    Effective December 30, 1997, the Company executed a $120.0 million revolving
credit facility ("Facility") with a group of banks. Borrowing under the Facility
may be made by the Company until the expiration of the Facility on December 30,
1999, at which time all principal is due. Outstanding loans under the Facility
bear interest at the Company's option of either the prime rate (7.75% at
December 31, 1998) or at the current London Interbank Offering Rate ("LIBOR")
(5.1% at December 31, 1998) plus 1%. The loan is collateralized in part by the
common stock of HC and AIC. The agreement contains restrictive covenants,
including minimum net worth requirements for the Company and certain
subsidiaries, restrictions on certain extraordinary corporate actions, notice
requirements for certain material occurrences and the maintenance of required
financial ratios.
 
    The acquisition note is a note payable to the former owner of Sun. The note
bears interest at 6.4% and is due January 5, 1999. It was paid subsequent to
year end utilizing funds received from a draw on the Facility.
 
    On March 8, 1999, the Company entered into a Loan Agreement (the "New
Facility") with a group of banks. The New Facility includes a $150.0 million
Revolving Loan Facility and $100.0 million Short Term Revolving Loan Facility.
Borrowing under the New Facility may be made from time to time by the Company
for general corporate purposes through the Short Term Revolving Loan Facility
until its expiration on March 7, 2000 and through the Revolving Loan Facility
until its expiration on February 28, 2002. Outstanding loans under the New
Facility bear interest at agreed upon rates. The New Facility is collateralized
in part by the pledge of the stock of HC, AIC, and USSIC and by the pledge of
stock and guaranties entered into by the Company's principal underwriting agency
and intermediary subsidiaries. The New Facility agreement contains certain
restrictive covenants, including, without limitation, minimum net worth
requirements for the Company and certain subsidiaries, restrictions on certain
extraordinary corporate actions, notice requirements for certain material
occurrences, and required maintenance of specified financial ratios. Management
believes that the restrictive covenants and other obligations of the Company
which are contained in the New Facility agreement are typical for financing
arrangements comparable to the New Facility. The initial funding available under
the New Facility was used, among other things, to refinance existing
indebtedness of the Company including all outstanding indebtedness under the
Company's $120.0 million revolving credit facility entered into as of December
30, 1997, which has been terminated.
 
    At December 31, 1998, several of the Company's subsidiaries maintained
revolving lines of credit with a bank in the combined maximum amount of $40.0
million available through December 30, 1999. Advances under the lines of credit
are limited to amounts required to fund draws, if any, on letters of credit
issued by the bank on behalf of the subsidiaries and short-term direct cash
advances. The lines of credit are collateralized by securities having an
aggregate market value of up to $50.0 million, the actual amount of

collateral at any one time being 125% of the aggregate amount outstanding.
Interest on the lines is payable at the bank's prime rate of interest (7.75% at
December 31, 1998). At December 31, 1998, letters of credit totaling $19.8
million had been issued to insurance companies by the bank on behalf of the
subsidiaries, with total securities of $24.8 million collateralizing the line.
 
(6) INCOME TAX
 
    Several of the Company's foreign subsidiaries are not subject to foreign
income taxes and no material foreign income tax expense was incurred for the
three years ended December 31, 1998. United States Federal income taxes are
provided on all foreign earnings. As of December 31, 1998 and 1997, the Company
had income taxes receivable of $2.9 million and $3.7 million, respectively,
included in other assets in the consolidated balance sheets. For Federal income
tax purposes, one subsidiary has approximately $3.2 million of net operating
loss carry forwards which will expire in the year 2010. The components of the
income tax provision for the three years ended December 31, 1998, are as
follows:

(7) SEGMENT AND GEOGRAPHIC DATA
 
    The Company classifies its activities into four operating business segments
based upon services provided: 1) property and casualty insurance company
operations, 2) underwriting agency operations, 3) intermediary operations, and
4) other operations. See Note 1 for a description of the services provided by
and the principal subsidiaries included in the insurance company, underwriting
agency and intermediary segments. The other operations perform various insurance
related services for insurance company subsidiaries and unaffiliated insurance
companies. Also included in other operations is income from strategic
operational investments. Corporate includes general corporate operations, and
those minor operations not included in an operating segment. Inter-segment
revenue consists primarily of management fees of the underwriting agency
segment, commission income of the intermediary segment and service revenue of
the other operations charged to the insurance company segment on business
retained by the Company's insurance company subsidiaries. Inter-segment pricing
(either flat rate fees or as a percentage premium) approximates what is charged
to unrelated parties for similar services.
 
    The performance of each segment is evaluated by management based upon net
earnings. Net earnings is calculated after tax and after all corporate expense
allocations, purchase price allocations and intercompany eliminations have been
charged or credited to the individual segments. The following tables show
information by business segment and geographic location. Geographic location is
determined by physical location of the Company's offices and does not represent
the location of insureds or reinsureds from whom the business was generated.

(8) REINSURANCE
 
    In the normal course of business the Company's insurance company
subsidiaries cede a substantial portion of their premium to non-affiliated
domestic and foreign reinsurers through quota share, surplus, excess of loss and
facultative reinsurance agreements. Although the ceding of reinsurance does not
discharge the primary insurer from liability to its policyholder, the
subsidiaries participate in such agreements for the purpose of limiting their
loss exposure and diversifying their business. Substantially all of the
reinsurance assumed by the Company's insurance company subsidiaries was
underwritten directly by the Company but issued by other non-affiliated
companies in order to satisfy local licensing or other

    The insurance company subsidiaries require reinsurers not authorized by
their respective states of domicile to collateralize their reinsurance
obligations to the Company with letters of credit or cash deposits. At December
31, 1998, the Company held letters of credit and cash deposits in the amounts of
$166.5 million and $8.1 million, respectively, to collateralize a portion of the

* Underwriters Indemnity Company was acquired by RLI Corporation, an insurance
holding company, in January, 1999.
 
    Approximately $2.1 million in recoverables is due from reinsurers that are
either under regulatory supervision or insolvent. The Company holds letters of
credit and cash deposits totaling $1.9 million to collateralize these balances
plus other credits of $1.1 million available for potential offset. The Company
is involved in a dispute with one reinsurer over coverage and other issues. The
Company believes the reinsurer's position is without merit and all amounts due
from the reinsurer will be recovered. The total amount in dispute is
approximately $2.3 million.

LITIGATION
 
    The Company is a party to numerous lawsuits arising in the normal course of
business. Many of the pending lawsuits involve claims under policies
underwritten or reinsured by the Company. Management believes that any liability
for such claims has been adequately included in its established loss reserves.
The Company believes the resolution of these lawsuits will not have a material
adverse effect on its financial condition, results of operations or cash flows.
 
FOREIGN CURRENCY FORWARD CONTRACTS
 
    The Company had no open foreign currency forward contracts as of December
31, 1998 or 1997. The Company may, from time to time, limit its exposure to
currency fluctuations through the use of foreign currency forward contracts. The
Company utilizes these foreign currency forward contracts strictly as a hedge
against existing exposure to foreign currency fluctuations rather than as a form
of speculative or trading investment.
 
LEASES
 
    The Company leases administrative office facilities under long-term
non-cancelable operating lease agreements expiring at various dates through
November, 2005. The agreements generally require the payment of utilities, real
estate taxes, insurance and repairs. The Company has recognized rent expense on
a straight-line basis over the terms of these leases. In addition, the Company
leases computer equipment and automobiles under operating leases expiring at
various dates through the year 2002. Rent expense under these leases amounted to
$4.3 million, $3.7 million and $2.5 million for the years ended December 31,
1998, 1997 and 1996, respectively.
 
    At December 31, 1998, future minimum annual rental payments required under
the long-term non-cancelable operating leases, excluding certain expenses
payable by the Company, are as follows:

CATASTROPHE EXPOSURE
 
    The Company writes business in areas exposed to catastrophic losses and has
significant exposures to this type of loss in California, the Atlantic Coast of
United States, certain United States Gulf Coast states, particularly Florida and
Texas, the Caribbean and Mexico. The Company assesses its overall exposures to a
single catastrophic event and applies procedures that it believes are more
conservative than are typically used by the industry to ascertain the Company's
probable maximum loss ("PML") from any single event.

    Substantially all of the insurance related amounts shown on the above tables
are due to balances and transactions with Underwriters Indemnity Company. Its
parent was majority owned by a Director and was 21% owned by the Company. Its
parent was sold to an unrelated party (RLI Insurance Company) in January, 1999.
 
    During 1997, the Company committed to invest $5.0 million in an investment
partnership managed by a related party. At December 31, 1998, $1.1 million had
been invested under this commitment. In 1998, HC bought an office building to be
occupied by the Company from a partnership in which an officer and director was
a partner. The purchase price of $6.0 million was based upon independent
appraisal.

(11)  EMPLOYEE BENEFIT PLANS
 
    The Company had various defined contribution retirement plans under Section
401(k) of the Internal Revenue Code which covered substantially all of the
domestic employees who met specified service requirements. All of these plans
were combined into one plan during 1998. The Company's contributions to these
plans were based on varying percentages of the employees' contributions, up to
varying maximum levels. The Company's contributions to the new combined plan are
discretionary and are determined by management as of the beginning of each
calendar year. The Company contributed $1.7 million, $858,000 and $997,000 to
the plans for the years ended December 31, 1998, 1997 and 1996, respectively,
which is included in compensation expense in the accompanying consolidated
statements of earnings.
 
    A company acquired in a pooling-of-interests transaction in 1997 had a
non-contributory defined benefit retirement plan covering substantially all of
its employees who met specified age and service requirements. This plan was
terminated in 1997, upon acquisition, at which time the participants' accounts
became fully vested. In accordance with applicable regulations, the plan's
assets were distributed to participants during 1998 and January 1999. Total
pension expense (credit) under the plan amounted to $(604,000), $0, and
($590,000), for the years ended December 31, 1998, 1997 and 1996, respectively.
A curtailment gain of $1.0 million was recognized in the 1996 pension credit as
a result of the acquired company's decision to eliminate certain future service
time credits.
 
(12)  SHAREHOLDERS' EQUITY
 
    Under the Texas Insurance Code, HC and USSIC must each maintain minimum
statutory capital of $1.0 million and minimum statutory surplus of $1.0 million,
and can only pay dividends out of statutory surplus funds. In addition, they are
limited in the amount of dividends which they may pay in any twelve month
period, without prior regulatory approval, to the greater of statutory net
income for the prior calendar year or ten percent (10%) of statutory capital and
surplus as of the prior calendar year end. During 1999, HC and USSIC's ordinary
dividend capacities will be approximately $38.2 million and $7.9 million,
respectively.
 
    AIC is limited by the state of Maryland in the amount of dividends which it
may pay in any twelve month period, without prior regulatory approval, to the
greater of statutory net income (under certain conditions) for the prior
calendar year or ten percent (10%) of statutory capital and surplus as of the
prior year end. During 1999, AIC's ordinary dividend capacity will be
approximately $10.5 million.
 
    As of December 31, 1998, all of the domestic insurance company subsidiaries
total adjusted capital greatly exceeded the NAIC authorized control level
risk-based capital.

(13)  STOCK OPTIONS
 
    The Company has five option plans, the 1994 Non-employee Director Stock
Option Plan, the 1996 Non-employee Director Stock Option Plan, the 1992
Incentive Stock Option Plan, the 1995 Flexible Incentive Plan, and the 1997
Flexible Incentive Plan. All plans are administered by the Compensation
Committee of the Board of Directors. Each option may be used to purchase one
share of Common Stock of the Company. As of December 31, 1998, 7,529,103 shares
of Common Stock were reserved for the exercise of options, of which 5,459,766
shares were reserved for options previously granted and 2,069,337 shares were
reserved for future issuances of options.
 
    Options vest over a zero to five year period and expire six to ten years
after grant date. All options have been granted at fixed exercise prices,
generally at the market price of the Company's Common Stock on the grant date.
Any excess of the market price on the grant date over the exercise price is
recognized as compensation expense in the accompanying consolidated financial
statements. During 1996, such compensation expense amounted to $494,000. If the
fair value method of valuing compensation related to options would have been
used, pro forma net earnings and pro forma diluted earnings per share would have
been $65.4 million, or $1.34 per share for the year ended December 31, 1998;
$43.8 million, or $0.91 per share, for the year ended December 31, 1997; and
$37.6 million, or $0.82 per share, for the year ended December 31, 1996. The
fair value of each option grant was estimated on the grant date using the Black-
Scholes single option pricing model with the following weighted average
assumptions:a) risk free interest rate of 5.3% for 1998, 6.2% for 1997 and 5.6%
for 1996, b) expected volatility factor of .3, c) dividend yield of .91% for
1998, .56% for 1997 and .3% for 1996, and d) expected option life of five years
for 1998 and 1997 and six years for 1996.

    As of December 31, 1998, there were approximately 1.7 million options that
were not included in the computation of diluted earnings per share because to do
so would have been antidilutive. There are 378,000 shares of the Company's
Common Stock to be issued in connection with an acquisition accounted for under
the purchase method of accounting, if certain conditions are met as of December
31, 1999 or in subsequent years. These shares were not included in the diluted
earnings per share computation, because the conditions for issuance have not yet
been met.

codification project, a comprehensive guide to statutory accounting principles
did not exist. Codification is new and will evolve over time. Based upon the
SSAPs as currently published, the Company does not expect their adoption to have
a material effect on the policyholders' surplus of its individual insurance
company subsidiaries. The only material effect on statutory net income is that
the statutory net income for HC will be decreased or increased by a change in
the method of recording equity in earnings or losses of subsidiaries. Currently
HC records the equity in earnings or losses of its subsidiaries as a component
of statutory net income. When codification becomes effective, the equity in
earnings or losses of subsidiaries will be recorded as an unrealized gain or
loss which is a direct increase or decrease to policyholders' surplus. Income
will not be recognized until such time (if any) that dividends are received from
the subsidiaries and recorded in statutory net income.

</TABLE>
 
    During 1998, the Company had net loss and LAE redundancy of $14.6 million
relating to prior year losses compared to redundancies of $3.8 million in 1997
and $4.9 million in 1996. The redundancies in the net reserves result from the
Company's and its advisors' continued review of its loss reserves and the
reduction of such reserves as losses are finally settled and claims exposures
are reduced. The Company believes it has provided for all material net incurred
losses.
 
    The Company has no material exposure to environmental pollution losses, as
HC only began writing business in 1981 and policies issued by HC normally
contain pollution exclusion clauses which limit pollution coverage to "sudden
and accidental" losses only, thus excluding intentional (dumping) and seepage
claims. Policies issued by AIC and USSIC, because of the types of risks
incurred, principally general aviation, are not considered to have significant
environmental exposures. Therefore, the Company should not experience any
material development in reserves from environmental pollution claims.

                    NOTE TO CONDENSED FINANCIAL INFORMATION
 
 (1) The accompanying condensed financial information should be read in
     conjunction with the consolidated financial statements and the related
     notes thereto of HCC Insurance Holdings, Inc. and Subsidiaries. Investments
     in subsidiaries are accounted for using the equity method.
 
 (2) Intercompany loans to subsidiaries are demand notes issued primarily to
     fund the cash portion of acquisitions. They bear interest at a rate set by
     management, which approximates the interest rate charged to the Company for
     similar debt. As of December 31, 1998, the interest rate on intercompany
     loans was 6 1/2%.

(1) Columns C and D are shown ignoring the effects of reinsurance.
 
(2) Net investment income was allocated to the company, and therefore the
    segment, on which the related investment asset was recorded. Other operating
    expenses were allocated to the company, and therefore the corresponding
    segment, which actually incurred those expenses.
 
Note: Column E is omitted because the Company has no other policy claims and
benefits payable.

                   SALE AND TRANSFER OF THE SUN COMMON STOCK

       SECTION 1.1   SALE OF SUN COMMON STOCK.

       (a)    Subject to the terms and conditions of this Agreement, 
Shareholder shall sell, transfer and deliver to HCC, and HCC shall purchase 
from Shareholder, all of the outstanding Sun Common Stock at the Closing, 
hereinafter defined.

       SECTION 1.2   PURCHASE PRICE.

       (a)    The purchase price ("Purchase Price") shall be equal to 
$24,660,000 and shall be paid by HCC to Shareholder as follows:

              (i)    $500,000 in cash (the "Cash Payment") shall be transferred
       by wire transfer at the Closing to such account as Shareholder shall
       specify, in immediately available funds; plus

              (ii)   at the Closing, HCC shall deliver to the Shareholder a
       promissory note in the original principal amount of $16,600,000 due
       January 5, 1998 (the "Note"); plus

              (iii)  378,000 shares of common stock, par value $1.00 per share,
       of HCC (the "HCC Common Stock") valued at the HCC Stock Value (the "Share
       Payment").  As used herein, the HCC Stock Value means $20.00 per share. 
       The Share Payment shall be paid as follows:

                     (a)    If the gross premium volume of Sun for 1999 equals
              or exceeds $80,000,000, then the entire Share Payment shall be
              made by March 1, 2000.

                     (b)    If the gross premium volume of Sun for 1999 is less
              than $80,000,000 but greater than the gross premium volume of Sun
              for 1998, then a portion of the Share Payment equal to the
              Achievement Percentage (defined below) multiplied by the full
              Share Payment shall be made by March 1, 2000.  As used herein, the
              "Achievement Percentage" means the ratio (i) the gross premium
              volume of Sun for 1999 less the gross premium volume of Sun for
              1998 bears to (ii) $80,000,000 less the gross premium volume of
              Sun for 1998.

                     (c)    If the Shareholder has received less then the full
              Share Payment, the Shareholder shall continue to be eligible to
              receive the remaining Share Payment with respect to subsequent
              years based on the respective Subsequent Year Achievement
              Percentages (defined below) for such subsequent years until the
              Share Payment has been made in full. As used herein, "Subsequent
              Year Achievement 

                                       2
<PAGE>

              Percentage" means the ratio (i) the actual gross premium volume 
              of Sun for the particular year less the actual gross premium 
              volume of Sun for the prior year bears to (ii) the target premium 
              volume of Sun for the particular year as agreed to by the 
              Shareholder and HCC less the actual gross premium volume of
              Sun for the prior year.  The portion of the Share Payment made
              with respect to any year subsequent to 1999 shall be equal to the
              excess, if any, of (x) the Subsequent Year Achievement Percentage
              with respect to such year multiplied by the full Share Payment,
              over (y) the cumulative portion of the Share Payment made with
              respect to all prior years.  The portion of the Share Payment with
              respect to any subsequent year shall be made by March 1 of the
              following year.

       The Share Payment shall be paid in full and shall become 
non-forfeitable upon a "Change of Control," as defined herein, of HCC, 
without regard to the provisions of clauses (a), (b), and (c) above.  As used 
in this Agreement, a Change of Control shall be deemed to have occurred if 
(1) any "person" or "group" (within the meaning of Section 13(d) and 14(d)(2) 
of the Securities Exchange Act of 1934) other than a trustee or other 
fiduciary holding securities under an employee benefit plan of HCC becomes 
the "beneficial owner" (as defined in Rule 13d-3 under the Securities 
Exchange Act of 1934) directly or indirectly of 50% or more of HCC's then 
outstanding voting common stock; (2) the shareholders of HCC approve a merger 
or consolidation with any other corporation, other than a merger or 
consolidation (a) in which a majority of the directors of the surviving 
entity were directors of HCC prior to such consolidation or merger or (b) 
which would result in the voting securities of HCC outstanding immediately 
prior thereto continuing to represent (either by remaining outstanding or by 
being changed into voting securities of the surviving entity) more than 50% 
of the combined voting power of the voting securities of the surviving entity 
outstanding immediately after such merger or consolidation; or (3) the 
shareholders approve a plan of complete liquidation of HCC or an agreement 
for the sale or disposition by HCC of all or substantially all of HCC's 
assets.

              (iv)   All HCC Common Stock to be delivered pursuant to this
       Agreement shall be restricted as to transfer and shall bear the following
       legend:

       "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
       REGISTERED UNDER THE SECURITIES ACT OF 1933.  THESE SHARES HAVE
       BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO DISTRIBUTION
       OR RESALE, AND MAY NOT BE SOLD, MORTGAGED, PLEDGED, HYPOTHECATED
       OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION
       STATEMENT FOR SUCH SHARES UNDER THE SECURITIES ACT OF 1933, OR AN
       OPINION OF COUNSEL FOR THE CORPORATION THAT SUCH REGISTRATION IS
       NOT REQUIRED UNDER SUCH ACT."

                                   ARTICLE 2

                        REPRESENTATIONS AND WARRANTIES 
                             OF SUN AND SHAREHOLDER

       Except as disclosed in a document referring specifically to this 
Agreement (the "Sun Disclosure Schedule") which has been delivered to HCC on 
or before the date hereof, Sun and the Shareholder (jointly and severally) 
represent and warrant to HCC as set forth below. 

       SECTION 2.1   CORPORATE EXISTENCE AND POWER.  Sun is a corporation 
duly organized, validly existing and in good standing under the laws of the 
state of its incorporation, and has all corporate powers and all material 
governmental licenses, authorizations, consents and approvals (collectively, 
"Governmental Authorizations") required to carry on its business as now 
conducted, except such Governmental Authorizations the failure of which to 
have obtained would not have a Material Adverse Effect, as hereinafter 
defined, on Sun.  Sun has delivered to HCC true and complete copies of Sun's 
Articles of Incorporation and Bylaws as currently in effect.  Sun is duly 
qualified to do business as a foreign corporation and is in good standing in 
each jurisdiction where the character of the property owned or leased by it 
or the nature of its activities makes such qualification necessary, except 
where the failure to be so qualified would not have a Material Adverse Effect 
on Sun.  For purposes of this Agreement, a "Material Adverse Effect," with 
respect to any person or entity (including without limitation Sun and  HCC), 
means a material adverse effect on the condition (financial or otherwise), 
business, properties, assets, liabilities (including contingent liabilities), 
results of operations or prospects of such person or entity and its 
affiliated companies and subsidiaries and/or parent corporation and/or 
corporations under the same stock ownership, taken as a whole; and "Material 
Adverse Change" means a change or a development involving a prospective 
change which would result in a Material Adverse Effect.

       SECTION 2.2   AUTHORIZATION.  Each of the Shareholder, Sun, and Barton

enforcement of creditors' rights generally or by general principles of equity.

       SECTION 2.3   GOVERNMENTAL AUTHORIZATION.  The execution, delivery and 
performance by the Shareholder, Sun and Barton, of this Agreement, and the 
consummation of the transactions contemplated hereunder require no action by 
Sun, the Shareholder, or Barton or any filing by any of them with any 
governmental body, agency, official or authority having authority over Sun, 
other than in respect of:

       (e)    such other filings or registrations with, or authorizations, 
consents or approvals of, governmental bodies, agencies, officials or 
authorities, the failure of which to make or obtain (i) would not reasonably 
be expected to have a Material Adverse Effect on Sun, or (ii) would not 
materially adversely affect the ability of any party to consummate the 
transactions contemplated hereby and operate their businesses as heretofore 
operated.

       SECTION 2.4   NON-CONTRAVENTION.  Except with HCC's knowledge and 
written consent, the execution, delivery and performance by the Shareholder,

applicable to Sun, the Shareholder, Barton, PASI, the Copperfield Drive LLC, 
KIMCO or North Bay;

       (c)    conflict with or result in a breach or violation of, or

Shareholder, Sun or Barton; or

       (e)    result in the loss of any material benefits relating to the 
ownership of the North Bay Share, 

except, with respect to clauses (b), (c) and (d) above, for contraventions, 
defaults, losses, Liens and other matters referred to in such clauses that in 
the aggregate would not be reasonably expected to 

                                       6
<PAGE>

have, individually or in the aggregate, a Material Adverse Effect on Sun.  
For purposes of this Agreement, the term "Lien" means, with respect to any 
asset, any mortgage, lien, pledge, charge, security interest or encumbrance 
of any kind in respect of such asset.

       SECTION 2.5   CAPITALIZATION.

       (a)    The entire authorized stock of Sun consists of 400 shares of 
common stock, $1.00 par value per share, of which, subsequent to the 
redemption referred to in Section 4.1(e) below, 94 shares are issued and 
outstanding, and 306 shares are held as treasury stock.  All of the issued 
and outstanding shares of stock of Sun are owned by the Shareholder free of 
any Liens or other encumbrances.  The Shareholder and Barton own of record 
the one share of common stock of Class F participating share of North Bay, 
and such ownership is free of any Liens or other encumbrances which have not 
been released.   Such North Bay Share is the only issued and outstanding 
Class F participating share of North Bay.  Sun owns a 50% membership interest 
in KIMCO.  Sun owns such membership interest free of any Liens or other 
encumbrances.  The entire capitalization of the Copperfield Drive LLC 
consists of a 50% membership interest owned by Shareholder and Barton and a 
50% membership interest owned by Sun, in each case free of any Liens or other 
encumbrances.  The entire authorized stock of PASI consists of 100 shares of 
Common Stock, $1.00 par value per share, of which 100 shares are issued and 
outstanding, and no shares are held as treasury stock. All of the issued and 
outstanding shares of stock of PASI are owned by Barton free of any Liens or 
other encumbrances.

       (b)    All outstanding shares and membership interests set forth in 
(a) above have been duly authorized and validly issued and are fully paid and 
nonassessable, and the issuer complied with all applicable preemptive rights 
in issuing such shares or membership interests.  Except as set forth in (a) 
above, there are outstanding (i) no shares of capital stock or other voting 
securities or equity interests, (ii) no securities convertible into or 
exchangeable for shares of its capital stock or voting securities or other 
equity interests, (iii) no options or other rights to acquire from any party, 
and no obligation to issue, any capital stock, voting securities or 
securities convertible into or exchangeable for its capital stock or other 
voting securities or equity interests (the items in clauses (i), (ii) and 
(iii) being referred to collectively as the "Sun Securities"), (iv) no 
obligations to repurchase, redeem or otherwise acquire any of Sun Securities 
and (v) no contractual rights of any person or entity to include any such 
securities in any registration statement proposed to be filed under the 
Securities Act.

       SECTION 2.6   SUBSIDIARIES AND RELATED ENTITIES.  

       (a)    Except as set forth in this Section, Sun does not control 
(whether directly or indirectly, and whether through the ownership of voting 
securities or by contract or proxy, and whether alone or in combination with 
others) any corporation, partnership, business organization or other similar 
entity.  KIMCO, PASI, and the Copperfield Drive LLC are collectively 
sometimes hereinafter referred to as the "Sun Affiliated Entities".

                                       7
<PAGE>

       (b)    Each Sun Affiliated Entity is duly organized, validly existing, 
and in good standing under the laws of the state of Alabama, and has all 
powers and all material Governmental Authorizations required to carry on its 
business as now conducted, except such Governmental Authorizations the 
failure of which to have obtained would not have a Material Adverse Effect on 
it.  Sun has delivered to HCC true and complete copies of the organizational 
documents of each Sun Affiliated Entity as currently in effect.  Each Sun 
Affiliated Entity is duly qualified to do business as a foreign entity and is 
in good standing in each jurisdiction where the character of the property 
owned or leased by it or the nature of its activities makes such 
qualification necessary, except where the failure to be so qualified would 
not have a Material Adverse Effect on it.

       SECTION 2.7   SUN FINANCIAL STATEMENTS.  Sun has delivered to HCC 
Sun's audited balance sheet (the "Audited Balance Sheet") as of June 30, 1998 
(the "Balance Sheet Date") and an unaudited balance sheet as of June 30, 
1997, Sun's audited income statements for the years ended June 30, 1998 and 
Sun's unaudited balance sheets and income statements for the year ended June 
30, 1997 (collectively, the "Sun Financial Statements").  The Sun Financial 
Statements present fairly in all material respects, substantially in 
conformity with generally accepted accounting principles consistently applied 
(except as indicated in the notes thereto), the financial position of Sun as 
of the dates thereof and results of operations and cash flows for the periods 
therein indicated (subject to the absence of certain footnotes in the case of 
unaudited financial statements).  Sun has no material debt, liability or 
obligation of any nature, whether accrued, absolute, contingent or otherwise, 
and whether due or to become due, that is not reflected, reserved against or 
disclosed in the Audited Balance sheet, including the notes thereto, except 
for (i) those that are not required to be reported in accordance with the 
aforesaid accounting principles; (ii) normal or recurring liabilities 
incurred since June 30, 1998 in the ordinary course of business or (iii) 
liabilities under this Agreement or as disclosed in the Sun Disclosure 
Schedule.

       SECTION 2.8   ABSENCE OF CERTAIN CHANGES.  Since June 30, 1998, Sun 
and each Sun Affiliated Entity has in all material respects conducted its 
business in the ordinary course and there has not been:

       (a)    any Material Adverse Change with respect thereto or any event, 
occurrence or development of a state of circumstances or facts known to Sun, 
which as of the date hereof could reasonably be expected to have a Material 
Adverse Effect on Sun;

       (b)    any declaration, setting aside or payment or any dividend or 
other distribution in respect of any shares of capital stock of Sun other 
than the declaration, setting aside or payment of dividends in accordance 
with its existing dividend policy or practice, which policy or practice is 
not inconsistent with Sun's past policy or practice;

       (c)    except as required by Section 4.1(e) hereof, any repurchase, 
redemption or other acquisition by Sun of any outstanding shares of capital 
stock or other securities of or other ownership interests in Sun;

                                       8

       (e)    any damage, destruction or other property or casualty loss 
(whether or not covered by insurance) affecting the business, assets, 
liabilities, earnings or prospects of Sun which, individually or in the 
aggregate, has had or would reasonably be expected to have a Material Adverse 
Effect on Sun or any Sun Affiliated Entity;

       (f)    any increase in indebtedness for borrowed money or capitalized 
lease obligations of Sun or any Sun Affiliated Entity, except in the ordinary 
course of business;

       (g)    any sale, assignment, transfer or other disposition of any 
tangible or intangible asset material to the business of Sun, except in the 
ordinary course of business and for a fair and adequate consideration;

       (h)    any amendment, termination or waiver by Sun or any Sun 
Affiliated Entity of any right of substantial value under any agreement, 
contract or other written commitment to which it is a party or by which it is 
bound;

       (i)    any material reduction in the amounts of coverage provided by 
existing casualty and liability insurance policies with respect to the

agreement (or any amendment to any such existing agreement) with any 
director, officer or employee of Sun, (iii) any increase in benefits payable 
under any existing severance or termination pay policies or employment 
agreements, or (iv) any increase in compensation, bonus or other benefits 
payable to directors, officers or employees of Sun or any Sun Affiliated 
Entity, in each case other than in the ordinary course of business consistent 
with past practice;

       (k)    any new or amendment to or alteration of any existing bonus, 
incentive, compensation, severance, stock option, stock appreciation right, 
pension, matching gift, profit-sharing, employee stock ownership, retirement, 
pension group insurance, death benefit, or other fringe benefit plan, 
arrangement or trust agreement adopted or implemented by Sun or any Sun 
Affiliated Entity which would result in a material increase in cost;

       (l)    any capital expenditures, capital additions or capital 
improvements in excess of $10,000; or

       (m)    the entering into of any agreement by Sun or any Sun Affiliated 
Entity or any person on behalf of Sun or any Sun Affiliated Entity to take

       SECTION 2.9   NO UNDISCLOSED LIABILITIES.  There are no existing 
liabilities of Sun or any Sun Affiliated Entity of any kind whatsoever that 
are, individually or in the aggregate, material to Sun, other than:

       (a)    liabilities disclosed, reserved against, or provided for in the 
Audited Balance Sheet (including the notes thereto);

       (b)    liabilities incurred in the ordinary course of business 
consistent with past practice since June 30, 1998; and

       (c)    liabilities under this Agreement or indicated in the Sun 
Disclosure Schedule.

       SECTION 2.10  LITIGATION.  The Sun Disclosure Schedule sets forth all 
actions, suits, proceedings, claims or investigations pending against Sun or 
any Sun Affiliated Entity or relating to its business or the North Bay Share. 
Neither Sun nor any Sun Affiliated Entity nor any Shareholder has received 
written notice of a claim threatened against Sun or any Sun Affiliated Entity 
or any of its assets or against or involving any of its officers, directors 
or employees in connection with the business or affairs of Sun or any Sun 
Affiliated Entity or the North Bay Share, including, without limitation, any 
such claims for indemnification arising under any agreement to which Sun or 
any Sun Affiliated Entity is a party.  Neither Sun nor any Sun Affiliated 
Entity has received written notice that it is subject, or in default with 
respect, to any writ, order, judgment, injunction or decree which could, 
individually or in the aggregate, have a Material Adverse Effect on Sun or 
any Sun Affiliated Entity.

       SECTION 2.11  TAXES.

       (a)    Sun and each Sun Affiliated Entity (i) has filed when due 
(taking into account extensions) with the appropriate federal, state, local, 
foreign and other governmental agencies, all material tax returns, estimates 
and reports required to be filed by it, (ii) either paid when due and payable 
or established adequate reserves or otherwise accrued on the Sun's Financial 
Statements all material federal, state, local or foreign taxes, levies, 
imposts, duties, licenses and registration fees and charges of any nature 
whatsoever, and unemployment and social security taxes and income tax 
withholding, including interest and penalties thereon ("Taxes") and there are 
no tax deficiencies claimed in writing by any Taxing authority and received 
by Sun or any Sun Affiliated Entity or the Shareholder that, in the 
aggregate, would result in any tax liability in excess of the amount of the 
reserves or accruals and (iii) has or will establish in accordance with its 
normal accounting practices and procedures accruals and reserves that, in the 
aggregate, are adequate for the payment of all Taxes not yet due and payable 
and attributable to any period preceding the Effective Time.  The Sun 
Disclosure Schedule sets forth those tax returns for all periods that 
currently are the subject of audit by any federal, state, local or foreign 
taxing authority.

       (b)    There are no material taxes, interest, penalties, assessments 
or deficiencies claimed in writing by any Taxing authority and received by 
Sun or any Sun Affiliated Entity or the 

                                       10
<PAGE>

Shareholder to be due in respect of any tax returns filed by Sun or any Sun 
Affiliated Entity (or any predecessor entity). Neither Sun nor any Sun 
Affiliated Entity nor any predecessor entity, has executed or filed with the 
Internal Revenue Service ("IRS") or any other Taxing authority any agreement 
or other document extending, or having the effect of extending, the period of 
assessment or collection of any Taxes.

       (c)    Neither Sun nor any Sun Affiliated Entity is a party to or 
bound by (or will prior to the Effective Date become a party to or bound by) 
any Tax indemnity, Tax sharing or Tax allocation agreement or other similar 
arrangement. Neither Sun nor any Sun Affiliated Entity is a member of an 
affiliated group or filed or been included in a combined, consolidated or 
unitary Tax return.

       SECTION 2.12  EMPLOYEE BENEFIT PLANS, ERISA.

       (a)    Neither Sun nor any Sun Affiliated Entity is a party to any 
oral or written (i) employment, severance, or consulting agreement not 
terminable on 60 days' or less notice, (ii) agreement with any executive 
officer or other key employee (A) the benefits of which are contingent, or 
the terms of which are materially altered, upon the occurrence of a 
transaction involving Sun or a Sun Affiliated Entity of the nature of any of 
the transactions contemplated by this Agreement, (B) providing any term of 
employment or compensation guarantee extending for a period longer than one 
year, or (C) providing severance benefits or other benefits after the 
termination of employment of such executive officer or key employee 
regardless of the reason for such termination of employment, or (iii) 
agreement or plan, including, without limitation, any stock option plan, 
stock appreciation right plan, restricted stock plan or stock purchase plan, 
the benefits of which would be increased, or the vesting of benefits of which 
will be accelerated, by the occurrence of any of the transactions 
contemplated by this Agreement or the value of any of the benefits of which 
will be calculated on the basis of any of the transactions contemplated by 
this Agreement.

       (b)    Except as described in the Sun Disclosure Schedule, neither Sun 
nor any corporation or other entity which under Section 4001(b) of the 
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), is 
under common control with Sun (a "Sun ERISA Affiliate") maintains or within 
the past five years has maintained, contributed to, or been obligated to 
contribute to, any "Employee Pension Benefit Plan" ("Pension Plan") or any 
"Employee Welfare Benefit Plan" ("Welfare Plan") as such terms are defined in 
Sections 3(2) and 3(1) respectively of ERISA, which is subject to ERISA.  
Each Pension Plan and Welfare Plan disclosed in the Sun Disclosure Schedule 
(which Plans have been heretofore delivered to HCC) and maintained by Sun 
has been maintained in all material respects in compliance with their terms 
and all provisions of ERISA and the Code (including rules and regulations 
thereunder) applicable thereto.

       (c)    No Pension Plan or Welfare Plan is currently subject to an 
audit or other investigation by the IRS, the Department of Labor (the "DOL"), 
the Pension Benefit Guaranty Corporation or any other governmental agency or 
office nor are any such Plans subject to any lawsuits or legal proceedings of 
any kind or to any material pending disputed claims by employees or 
beneficiaries covered under any such Plan or by any other parties.

                                       11
<PAGE>

       (d)    No "prohibited transaction," as defined in Section 406 of ERISA or
Section 4975 of the Code, resulting in liability to Sun or any Sun ERISA
Affiliate has occurred with respect to any Pension Plan or Welfare Plan. 
Neither Sun nor the Shareholder has any knowledge of any breach of fiduciary
responsibility under Part 4 of Title I of ERISA which has resulted in liability
of Sun and Sun ERISA Affiliate, any trustee, administrator or fiduciary of any
Pension Plan or Welfare Plan.

       (e)    Neither Sun nor any Sun ERISA Affiliate, since January 1, 1986,
has maintained or contributed to, or been obligated or required to contribute
to, a "Multiemployer Plan," as such term is defined in Section 4001(a)(3) of
ERISA.  Neither Sun nor any Sun ERISA Affiliate has either withdrawn, partially
or completely, or instituted steps to withdraw, partially or completely, from
any Multiemployer Plan nor has any event occurred which would enable a
Multiemployer Plan to give notice of and demand payment of any withdrawal
liability with respect to Sun or any Sun ERISA Affiliate.

       (f)    Except as described in the Sun Disclosure Schedule, there is no
contract, agreement, plan or arrangement covering any employee or former
employee of Sun or any Sun ERISA Affiliate that, individually or collectively,
could give rise to the payment of any amount that would not be deductible
pursuant to the terms of Sections 162(a)(I) or 280G of the Code.

       (g)    With respect to Sun and each Sun ERISA Affiliate, the Sun
Disclosure Schedule correctly identifies each material agreement, policy, plan
or other arrangement, whether written or oral, express or implied, fixed or
contingent, other than plans disclosed in the Sun Disclosure Schedule pursuant
to Section 2.12(b) above, to which Sun is a party or by which Sun is bound,
which is or relates to a pension, option, bonus, deferred compensation,
employment, retirement, stock purchase, profit-sharing, severance pay, health,
welfare, incentive, vacation, sick leave, medical disability, hospitalization,
life or other insurance or fringe benefit plan, policy, arrangement, or
agreement.

       (h)    Neither Sun nor any Sun ERISA Affiliate maintains or has
maintained or contributed to any Pension Plan that is or was subject to
Section 302 of Title IV of ERISA or Section 412 of the Code.  Sun has made
available to HCC, for each Pension Plan which is intended to be "qualified"
within the meaning of Section 401(a) of the Code, a copy of the most recent
determination letter issued by the IRS to the effect that each such Plan is so
qualified and that each trust created thereunder is tax exempt under Section 501
of the Code, and Sun is unaware of any fact or circumstances that would
jeopardize the qualified status of each such Pension Plan or the tax exempt
status of each trust created thereunder.

       SECTION 2.13  MATERIAL AGREEMENTS.

       (a)    The Sun Disclosure Schedule includes a complete and accurate list
of all contracts, agreements, leases (other than Sun Property Leases, as
hereinafter defined), and instruments to which Sun or any Sun Affiliated Entity
is a party or by which it or its properties or assets are bound which
individually involve net payments or receipts in excess of $25,000 per annum,
inclusive of contracts 


                                      12
<PAGE>

entered into with customers and suppliers in the ordinary course of business, 
or that pertain to employment or severance benefits for any officer, director 
or employee of Sun or any Sun Affiliated Entity, whether written or oral (the 
"Material Sun Agreements").

       (b)    Neither Sun nor any Sun Affiliated Entity nor, to the knowledge of
Sun, any other party is in default under any Material Sun Agreement and no event
has occurred which (after notice or lapse of time or both) would become a breach
or default under, or would permit modification, cancellation, acceleration or
termination of any Material Sun Agreement or result in the creation of any
security interest upon, or any person obtaining any right to acquire, any
properties, assets or rights of Sun or any Sun Affiliated Entity, which, in any
such case, has had or would reasonably be expected to have a Material Adverse
Effect.

       (c)    To the knowledge of Sun, each such Material Sun Agreement is in
full force and effect and is valid and legally binding and there are no material
unresolved disputes involving or with respect to any Material Sun Agreement. 
Except as described in the Sun Disclosure Schedule, no party to a Material Sun
Agreement has advised Sun or the Shareholder that it intends either to terminate
a Material Sun Agreement or to refuse to renew a Material Sun Agreement upon the
expiration of the term thereof.  No representation or warranty is made that all
benefits contemplated in the Material Sun Agreements will be received.

       (d)    Neither Sun nor any Sun Affiliated Entity is in violation of, or
in default with respect to, any term of any of its organizational documents.

       SECTION 2.14  PROPERTIES.  Neither Sun nor any Sun Affiliated Entity owns
any real estate other than as described in the Sun Disclosure Schedule, and all
leases of real property to which Sun or an Sun Affiliated Entity is a party or
by which it is bound ("Sun Property Leases") are in full force and effect and
are set forth on the Sun Disclosure Schedule.  There exists no default under
such Sun Property Leases, nor any event which with notice or lapse of time or
both would constitute a default thereunder, which default would have a Material
Adverse Effect.  All of the properties and assets which are owned by Sun or an
Sun Affiliated Entity are owned free and clear of any Lien, except for Liens
described in the Sun Disclosure Schedule or Permitted Liens (as defined below). 
Sun or such Sun Affiliated Entity has good and indefeasible title with respect
to such owned properties and assets subject to no Liens, other than those
described in the Sun Disclosure Schedule or Liens permitted under this
Section 2.14, and to all of the properties and assets necessary for the conduct
of their business other than to the extent that the failure to have such title
would not have a Material Adverse Effect.  "PERMITTED LIENS" shall mean (i) any
lien, encumbrance or defect which does not materially detract from the fair
market value (free of such lien, encumbrance or defects) of the property or
assets subject thereto or materially interfere with the current use by Sun of
the property or assets subject thereto or affected thereby, (ii) any liens or
encumbrances for taxes not delinquent or which are being contested in good
faith, provided that adequate reserves for the same have been established in the
most recent financial statements of Sun to the extent required by GAAP applied
on a consistent basis, (iii) any liens or encumbrances for current taxes and
assessments not yet past due, and (iv) any inchoate mechanics and materialmen's
liens and encumbrances for construction in 


                                      13
<PAGE>

process, (iv) any workmen's, repairmen's, warehousemen's and carrier's liens 
and encumbrances arising in the ordinary course of business which do not in 
the aggregate materially detract from the value of Sun's business assets or 
properties or materially impair the use thereof or which are being contested 
in good faith by appropriate proceedings which have the effect of preventing 
the forfeiture or sale of such business or property subject to any such lien 
or encumbrance and for which adequate reserves have been established in 
accordance with GAAP.

       SECTION 2.15  ENVIRONMENTAL MATTERS.

       (a)    For the purposes of this Agreement, the following terms have the
following meanings:

              "Environmental Laws" shall mean any and all federal, state, local

       discharges or releases of pollutants, contaminants, Hazardous Substances
       (as hereinafter defined) or wastes into the environment or otherwise
       relating to the manufacture, processing, distribution, use, treatment,

       thereof.

              "Environmental Liabilities" shall mean all liabilities, whether
       vested or unvested, contingent or fixed, actual or potential, which
       (i) arise under or relate to Environmental Laws and (ii) relate to
       actions occurring or conditions existing on or prior to the Effective
       Time.

              "Hazardous Substances" shall mean any toxic, radioactive, caustic
       or otherwise hazardous substance, including petroleum, its derivatives,
       by-products and other hydrocarbons, or any substance having any
       constituent elements displaying any of the foregoing characteristics.

              "Regulated Activity" shall mean any generation, treatment,
       storage, recycling, transportation, disposal or release of any Hazardous
       Substances.

       (b)    No notice, notification, demand, request for information,
citation, summons, complaint or order has been received, no complaint has been
filed, no penalty has been assessed and no investigation or review is pending,
or to the knowledge of Sun or any Shareholder, has been threatened by any
governmental entity or other party with respect to any (i) alleged violation of
any Environmental Law, (ii) alleged failure to have any environmental permit,
certificate, license, approval, registration or authorization required in
connection with the conduct of its business or (iii) Regulated Activity.

       (c)    Neither Sun nor any Sun Affiliated Entity has any material

applicable provisions of any laws, statutes, ordinances or regulations or any
term of any judgment, decree, injunction or order binding against it.

       SECTION 2.18  TRADEMARKS, TRADE NAMES, ETC.  Sun owns or possesses, or
holds a valid right or license to use, all intellectual property, patents,
trademarks, trade names, servicemarks, copyrights and licenses, and all rights

be under no obligation to register the shares of HCC Common Stock under the
Securities Act or to take any steps to assist the Shareholder to 


                                      15

comply with any applicable exemption under the Securities Act with respect to

       SECTION 2.22  INVESTMENTS.  (a) The Sun Disclosure Schedule sets forth a
true and complete list of all bonds, stocks, mortgages and other investments of
any type owned by Sun as of the date hereof (collectively, the "Scheduled
Investments").  Sun has good and marketable title to each of the Scheduled
Investments.

       (b)    Except as set forth on the Sun Disclosure Schedule, none of the
Scheduled Investments is currently in default in the payment of principal or
interest, and, to the knowledge of the Shareholder, no event has occurred which
reasonably would be expected to result in a diminution of the value of any
nonpublicly traded security owned by Sun.

       (c)    There are no Liens on any of the Scheduled Investments, except for
(i) those Scheduled Investments deposited with governmental authorities, as
indicated on the Sun Disclosure Schedule, (ii) Liens which do not materially
detract from the value of the Scheduled Investments subject thereto, and (iii)
assets pledged to secure assumed reinsurance contract obligations which assets
are listed on the Sun Disclosure Schedule.

       (d)    Neither any of the Shareholder nor Sun has taken or omitted to
take, any action which would result in Sun being unable to enforce the terms of
any Scheduled Investment or which would cause any Scheduled Investment to be
subject to any valid offset, defense or counterclaim against the right of Sun to
enforce the terms of such Scheduled Investment.

       (e)    Since June 30, 1998, Sun has not (i) purchased or otherwise
invested in, or committed to purchase or otherwise invest in, any interest in
real property (including without limitation any extension of credit secured by a
mortgage or deed of trust), (ii) purchased or otherwise invested in, or
committed to purchase or otherwise invest in, bonds, notes, debentures or other
evidences of indebtedness rated lower than "Baa" by Moody's Investors Service
Inc. or "BBB" by Standard & Poor's Corporation at the time of purchase, (iii)
entered into any contract, agreement or arrangement with any affiliate with
respect to the purchase or other acquisition, sale or other disposition or
allocation of any Scheduled Investment or (iv) entered into any contract,
agreement or arrangement with respect to any foreign investments.

       SECTION 2.23  INVESTMENT COMPANY.  Sun is not an "investment company"
within the meaning of the Investment Company Act of 1940.

       SECTION 2.24  LICENSES.   Except as described in the Sun Disclosure
Schedule, Sun and the Sun Affiliated Entities and North Bay possess all material
licenses, certificates, authorizations and permits issued by, and have made all
declarations and filings with, the appropriate federal, state or foreign
regulatory agencies or bodies which are necessary or desirable for the ownership
of the properties of Sun, the Sun Affiliated Entities and the North Bay Share or
the conduct of the business of Sun, the Sun Affiliated Entities and North Bay
and neither Sun nor the Sun Affiliated Entities nor 


                                      16
<PAGE>

North Bay has received notification of any revocation or modification of any 
such license, certificate, authorization or permit and neither Sun, the Sun 
Affiliated Entities, nor North Bay, nor the Shareholder has any reason to 
believe that any such license, certificate, authorization or permit will not 
be renewed in the ordinary course.

       SECTION 2.25  INTERNAL CONTROLS.  Sun maintains a system of internal
accounting controls, which Sun reasonably believes is  sufficient to provide
reasonable assurances that (i) transactions are executed in accordance with
management's general or specific authorization; (ii) transactions are recorded
as necessary to permit preparation of financial statements in conformity with
generally accepted accounting principles and to maintain asset accountability;
(iii) access to assets is permitted only in accordance with management's general
or specific authorization; and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate
actions are taken with respect to any differences.

       SECTION 2.26  INSURANCE.  Sun has insurance covering its properties,
operations, personnel and businesses, which insurance is in amounts and insures
against such losses and risks as are adequate to protect Sun and its businesses.
Sun has not received notice from any insurer or agent of such insurer that
capital improvements or other expenditures are required and necessary to be made
in order to continue such insurance.

       SECTION 2.27  FINANCIAL SOLVENCY.  On and immediately after the Closing
Date, Sun will be "Solvent."  As used in this paragraph, the term "Solvent"
means, with respect to a particular date, that on such date (i) the present fair
market value (or present fair salable value) of the assets of Sun is not less
than the total amount required to pay the probable liabilities of Sun on its
total existing debts and liabilities (including contingent liabilities) as they
become absolute and matured; (ii) Sun is able to realize upon its assets and pay
its debts and other liabilities, contingent obligations and commitments as they
mature and become due in the normal course of business; (iii) Sun has not
incurred debts or liabilities beyond its ability to pay such debts and
liabilities as they mature; and (iv) Sun does not engage in any business or
transaction and is not about to engage in any business or transaction for which
its property would constitute unreasonably small capital after giving due
consideration to the prevailing practice of the industry in which Sun is
engaged.  In computing the amount of such contingent liabilities at any time, it
is intended that such liabilities will be computed at the amount that, in light
of all the facts and circumstances existing at such time, represents the amount
that can reasonably be expected to become an actual or matured liability.

       SECTION 2.28  YEAR 2000 ISSUE.  Sun is currently evaluating its
operations and systems to determine the risk of computer hardware and software
used by it becoming unable to recognize and properly execute date-sensitive
functions involving certain dates prior to and any dates after December 31, 1999
(the "Year 2000 Issue") and has determined that such risk will be remedied on a
timely basis without material expense and will not have a Material Adverse
Effect.

       SECTION 2.29  NORTH BAY ASSETS.  North Bay owns and controls, free of any
Liens or encumbrances, each of the assets set forth on Schedule 2.29 attached
hereto.  North Bay began 


                                      17
<PAGE>

beneficially holding ceded insurance premiums allocable to the Class F 
Participating share on January 1, 1997.  Such assets have accumulated since 
Shareholder and Barton have owned of record the North Bay Share and there 
has never been a distribution of any cash or other assets to any of the 
holders or owners of record of the North Bay Share.

material license, franchise, permit or other similar authorization held by HCC,
except, with respect to clauses (b) and (c) above, for contraventions, defaults,
losses, and other matters referred to in such clauses that in the aggregate
would not be reasonably expected to have, individually or in the aggregate, a
Material Adverse Effect on HCC.

       SECTION 3.7   ABSENCE OF CERTAIN CHANGES.  Since the date of filing with
the SEC of its most recent quarterly report on Form 10-Q, there has not been any

statutes, ordinances, or regulations or any term of any judgment, decree,
injunction, or order binding against it.

       SECTION 3.9   BROKER'S FEES.  Neither HCC nor anyone acting on behalf of

and HCC shall have provided the Shareholder with a certificate executed by 
an authorized officer of each of HCC, dated as of the Closing Date, to such 
effect.  For the purposes of determining the accuracy of the representations 
and warranties of HCC, any change or effect in the business of HCC that 
results in substantial part as a consequence of the public announcement or 
pendency of the intended acquisition of the Sun Common Stock by HCC shall 
not be deemed a Material Adverse Change or Material Adverse Effect or other 
breach of representation or warranty with respect to HCC.

       (b)    HCC shall have performed and complied with all of its 
covenants contained herein in all material respects on or before the Closing

enforced (and not repealed, superseded or otherwise made inapplicable) by any 
court or governmental authority which prohibits the consummation of the 
transaction contemplated by this Agreement (each party agreeing to use its 
commercially reasonable efforts to have any such order, decree or injunction 
lifted).

       (b)    There shall have been obtained any and all Governmental 
Authorizations, permits, approvals and consents of securities or "blue sky" 
commissions of any jurisdiction and of any other governmental body or agency, 
that may reasonably be deemed necessary so that the consummation of the

                                INDEMNIFICATION

       SECTION 10.1  SHAREHOLDER AGREEMENT TO INDEMNIFY.  Subject to the 
limitations set forth in this Article 10, from and after the Effective Time, 
the Shareholder will indemnify and hold harmless HCC and its officers, 
directors, agents, employees, successors, and assigns and each person, if 
any, who controls or may control HCC within the meaning of the Securities 
Act (hereinafter referred to individually as a "Sun Indemnified Person" and 
collectively as "Sun Indemnified Persons") from and against any and all 
claims, demands, actions, causes of action, losses, costs, damages, 
liabilities and expenses including, without limitation, reasonable legal 
fees, (net of: (i) any recoveries under insurance policies or any amounts 
that would have been recoverable under insurance policies if the Surviving 
Corporation had continued to maintain the same insurance coverage maintained 
by Sun on the date of this Agreement; (ii) recoveries from third parties; and 
(iii) tax savings known to Sun Indemnified Persons at the time of making of 
claims hereunder) made against or incurred by Sun Indemnified Persons 
(hereafter in this Section 10 referred to as "HCC Damages"), arising out of 
any material misrepresentation or breach of or default under any of the 
representations, warranties, covenants or agreements given or made in this 
Agreement or any certificate or exhibit delivered by or on behalf of Sun or 
the Shareholder pursuant hereto.  The indemnification provided for in this 
Section 10.1 will not apply unless and until the aggregate HCC Damages for 
which one or more Sun Indemnified Persons seeks indemnification exceeds 
$150,000 in the aggregate, in which event the indemnification provided for 
will include all HCC Damages (a franchise deductible).  The Sun Indemnified 
Persons are only entitled to be reimbursed for the actual indemnified 
expenditures or damages incurred by them for the above described losses.  
Such Sun Indemnified Persons are not entitled to consequential, special, or 
other speculative or punitive categories of damages.  Notwithstanding the 
foregoing, in no event shall the Shareholder have any obligation for 
indemnification pursuant to this Section 10.1 in excess of an aggregate of 
$15,000,000.

       SECTION 10.2  INDEMNIFICATION WITH RESPECT TO TAXES AND LICENSING.  In 
addition to the indemnification provided in Section 10.1 above, the 
Shareholder will indemnify and hold harmless the Sun Indemnified Persons from 
and against all HCC Damages, whenever incurred, arising out of: (i) any 
Taxes including, without limitation any Taxes accruing out of the redemption 
of stock in exchange for the Barton Ridge Property and other property set 
forth in Section 4.1(e) or (ii) from the failure to have obtained any license 
including without limitation, any managing general agent's license, relating 
to the business of Sun or any Sun Affiliated Entity or North Bay attributable 
to any period preceding the Effective Time.

       SECTION 10.3  INDEMNIFICATION FOR OTHER SPECIFIED CLAIMS.  In addition 
to the indemnification provided in Sections 10.1 and 10.2 above, the 
Shareholder will indemnify and hold harmless the Sun Indemnified Persons from

or claimed liability of Sun or any Sun Affiliated Entity or Shareholder or

       SECTION 10.4   HCC AGREEMENT TO INDEMNIFY.  Subject to the limitations 
set forth in this Article 10, from and after the Effective Time, HCC will 
indemnify and hold harmless the Shareholder, Barton and each of their 
administrators, heirs, personal representatives, successors and assigns 
(hereinafter in this Section 10.4 referred to individually as an "HCC 
Indemnified Person" and collectively as "HCC Indemnified Persons") from and 
against any and all claims, demands, actions, causes of action, losses, 
costs, damages, liabilities and expenses including, without limitation, 
reasonable legal fees (net of: (i) any recoveries under insurance policies; 
(ii) recoveries from third parties; and (iii) tax savings known to HCC 
Indemnified Persons at the time of making a claim hereunder) (hereafter in 
this Section 10.4 referred to as "Sun Damages") arising out of any 
misrepresentation or breach of or default under any of the representations, 
warranties, covenants and agreements given or made by HCC in this Agreement 
or any certificate or exhibit delivered by or on behalf of HCC pursuant 
hereto.  The indemnification provided for in this Section 10.4 will not apply 
unless and until the aggregate Sun Damages for which one or more HCC 
Indemnified Person seeks indemnification exceeds $150,000 in the aggregate, 
in which event the indemnification provided for will include all Sun Damages 
(a franchise deductible).  The HCC Indemnified Persons are only entitled to 
be reimbursed for the actual indemnified expenditures or damages incurred by 
them for the above described losses.  Such HCC Indemnified Persons are not 
entitled to consequential, special, or other speculative or punitive 
categories of damages.  Notwithstanding the foregoing, in no event shall HCC 
have any obligation for indemnification pursuant to this Section 10.4 in 
excess of an aggregate of $15,000,000.

       SECTION 10.5  INDEMNIFICATION OF CLAIM BY INTERNATIONAL SPECIAL RISKS, 
LTD.   In addition to the indemnification provided in Section 10.4 above, HCC 
will indemnify and hold harmless the HCC Indemnified Persons from and against 
all Sun Damages, whenever incurred, arising out of any liability or claims of 
liability of the Shareholder or any affiliate of the Shareholder regarding 
the contract between Sun and International Special Risks, Ltd. and HCC will 
not seek any indemnity from the Shareholder with respect to any such claim.

       SECTION 10.6  SURVIVAL OF REPRESENTATIONS.  Unless any representation, 
warranty, covenant or agreement is required to terminate at an earlier time 
in order to maintain the applicable pooling-of-interests accounting 
treatment, each representation, warranty, covenant and agreement set forth in 
this Agreement will remain operative and in full force and effect for a 
period of one year after the Closing (the last date of such one year period 
being herein called the "Final Date"), regardless of any investigation made 
by or on behalf of the parties to this Agreement, upon which Final Date such 
representations, warranties, covenants and agreements shall expire and be of 
no further force and effect except for the covenants set forth in Section 6.5 
hereof and except that the indemnification provided for in Sections 10.2 and 
10.3 of this Agreement shall survive until a final resolution of all such 
matters.  Except as provided in the preceding sentence, any litigation or 
other action of any kind arising out of or attributable to a breach of any 
representation, warranty, covenant or agreement contained in this Agreement, 
must be commenced prior to the Final Date.  If not so commenced prior 

                                       36
<PAGE>

to the Final Date, any claims or indemnifications brought under this Article 
10 (except for those relating to a breach of the covenants set forth in 
Section 6.5 hereof or relating to indemnification under Sections 10.2 or 10.3 
hereof) will thereafter conclusively be deemed to be waived regardless of 
when such claim is or should have been discovered.  Any such claim for 
indemnification brought under this Article 10, brought before the Final Date, 
shall survive until a final resolution of such claim is effective.  As set 
forth herein, no investigation by any party hereto into the business, 
operations and conditions of the other party shall diminish in any way the 
effect of any representation or warranty made by any such party in this 
Agreement or shall relieve any party of any of its obligations under this 
Agreement.

       SECTION 10.7  PROCEDURE FOR INDEMNIFICATION; THIRD PARTY CLAIMS.  

       (a)    Promptly after receipt by an indemnified party under this 
Article 10 of notice of a claim against it for indemnification brought under 
this Article 10 (a "Claim"), the indemnified party will, if a claim is to be 
made against an indemnifying party, give prompt written notice to the 
indemnifying party of the Claim, but the failure to promptly notify the 
indemnifying party will not relieve the indemnifying party of any liability 
that it may have to any indemnified party, except to the extent that the 
indemnifying party demonstrates that the defense of such action is prejudiced 
by the indemnified party's failure to give such prompt notice.  Such notice 
shall contain a description in reasonable detail of facts upon which such 
Claim is based and, to the extent known, the amount thereof.

       (b)    If any Claim referred to in this Article 10 is made by a third 
party against an indemnified party and such indemnified party gives written 
notice to the indemnifying party of the Claim, the indemnifying party will be 
entitled to participate in the defense of Claim and, to the extent that it 
wishes to assume the defense of the Claim and, after written notice from the 
indemnifying party to the indemnified party of its election to assume the 
defense of the Claim, the indemnifying party shall assume such defense and 
will not be liable to the indemnified party under this Article 10 for any 
fees of other counsel or any other expenses with respect to the defense of 
the Claim in each case subsequently incurred by the indemnified party in 
connection with the defense of the Claim

                                   ARTICLE 11

                                 MISCELLANEOUS

       SECTION 11.1  FURTHER ASSURANCES.  Each party agrees to cooperate

reflect the transactions described herein and contemplated hereby and to 
carry into effect the intents and purposes of this Agreement.

parties, each party shall bear its own fees and expenses, including counsel 
fees and fees of brokers and investment bankers contracted by such party, in

if the transaction contemplated by this Agreement is consummated, the 
expenses of Shareholder and Barton shall be paid by Sun.

                              EMPLOYMENT AGREEMENT

     This Employment Agreement ("Agreement") is entered into as of the 1st 
day of January, 1998 (the "Effective Date"), between HCC INSURANCE HOLDINGS, 
INC. ("HCC" or "Company"), and JOHN N. MOLBECK, JR. ("Executive"), sometimes 
collectively referred to herein as the "Parties."


                                R E C I T A L S:

     WHEREAS, Executive is to be employed as President of HCC, and, as an 
integral part of its management who participates in the decision-making 
process relative to short and long-term planning and policy for the Company, 
will serve on the Company's Executive Committee;

     WHEREAS, it is the desire of the Board of Directors of HCC (the "Board") 
to (i) directly engage Executive as an officer of HCC and its subsidiaries; 
and (ii) directly engage, if elected, the services of Executive as a director 
of HCC and its subsidiaries; and

     WHEREAS, Executive is desirous of committing himself to serve HCC on the 
terms herein provided.

     NOW, THEREFORE, in consideration of the foregoing and of the respective 
covenants and agreements set forth below, the Parties agree as follows:

     2.   TERM.  The Company hereby agrees to employ Executive as its 
President, and Executive hereby agrees to accept such employment, on the 
terms and conditions set forth herein, for the period commencing on the 
Effective Date and expiring as of 11:59 p.m. on December 31, 2002 (the "Basic 
Term") (unless sooner terminated as hereinafter set forth).  On or before 
December 31, 1999, Executive shall assume the additional responsibilities of 
Chief Executive Officer of HCC.

     3.   DUTIES.

          (a)  DUTIES AS EMPLOYEE OF THE COMPANY.  Executive shall, subject 
to the supervision of the Chief Executive Officer and Board (until such time 
as Employee is elected Chief Executive Officer, at which time Employee shall 
be subject to the supervision of the Chairman of the Board and Board), have 
general management and control of HCC in the ordinary course of its business 
with all such powers with respect to such management and control as may be 
reasonably incident to such responsibilities.  During normal business hours, 
Executive shall devote his full time and attention to diligently attending to 
the business of the Company during the Basic Term.  During the Basic Term, 
Executive shall not directly or indirectly render 

EMPLOYMENT AGREEMENT - Page 1
<PAGE>

any services of a business, commercial, or professional nature to any other 
person, firm, corporation, or organization, whether for compensation or 
otherwise, without the prior written consent of the Chairman of the Board.  
However, Executive shall have the right to engage in such activities as may 
be appropriate in order to manage his personal investments so long as such 
activities do not materially interfere or conflict with the performance of 
his duties to the Company hereunder.  The conduct of such activity shall not 
be deemed to materially interfere or conflict with Executive's performance of 
his duties until Executive has been notified in writing thereof and given a 
reasonable period in which to cure the same.  

          (b)  OTHER DUTIES.  At all times during the Basic Term, the Company 
shall use its best efforts to cause Executive to be elected a director and to 
serve on the Executive Committee and Senior Management Committee of HCC.  Any 
such failure to use its best efforts prior to a Change of Control shall be a 
material breach of this Agreement for purposes of Paragraph 4(a)(iv).  If 
elected, Executive agrees to serve as a director and on the Executive 
Committee and Senior Management Committee of HCC and of any of its 
subsidiaries and in one or more executive offices of any of HCC's 
subsidiaries, provided Executive is indemnified for serving in any and all 
such capacities in a manner acceptable to the Company and Executive.  If 
elected, Executive agrees that he shall not be entitled to receive any 
compensation for serving as a director of HCC or in any capacities of HCC's 
subsidiaries other than the compensation to be paid to Executive by the 
Company pursuant to this Agreement.

     4.   COMPENSATION AND RELATED MATTERS.  

          (a)  BASE SALARY.  Executive shall receive a base salary paid by 
the Company at the annual rate of $500,000, during the period beginning on 
the Effective Date payable not less frequently than in substantially equal 
monthly installments.  The base salary shall be increased by $25,000 each 
January 1, commencing January 1, 1999, until Executive's base salary reaches 
$600,000.  For purposes of this Agreement, "Base Salary" shall mean the 
Executive's initial base salary and, when increased, the increased base 
salary.

          (b)  BONUS PAYMENTS.  Each year Executive shall be entitled to 
receive, in addition to the Base Salary, an annual bonus payment based on 
HCC's annual operating earnings per share ("OEPS") as set forth below:

          $50,000 bonus if OEPS growth is 10% or more in any one year;

          $100,000 bonus if OEPS growth is 15% or more in any one year
          period; and

          $200,000 bonus if OEPS growth is 20% or more in any one year
          period.

For purposes of this Agreement, OEPS is defined as HCC's consolidated net 
earnings less capital gains/losses, currency gains/losses, and any 
nonrecurring merger and acquisition income or

<PAGE>

expenses as reported in HCC's Annual Report on Form 10-K.

          (c)  STOCK OPTIONS.  In addition to stock options previously 
granted to Executive, if any, in partial consideration for Executive's 
non-competition agreement, set forth herein, Executive shall be provided with 
additional options to purchase HCC shares as follows:

          (1)  On January 7, 1998, an option to acquire 200,000
               shares, exercisable at a price of $16.50 per share and
               vesting at 20% per year beginning on December 31, 1998
               and on each of the four December 31st thereafter;

          (2)  For each year beginning with the year ending
               December 31, 1999, of Executive's employment hereunder;

          15,000 shares if, on such December 31, the price of the HCC
          Common Stock has increased since the previous January 1, by
          an amount that is greater than or equal to 10%, but less
          than 15%;

          20,000 shares if, on such December 31, the price of the HCC
          Common Stock has increased since the previous January 1, by
          an amount that is greater than or equal to 15%, but less
          than 20%;

          25,000 shares if, on such December 31, the price of the HCC
          Common Stock has increased since the previous January 1, by
          an amount that is greater than or equal to 20%, but less
          than 25%; and

          30,000 shares if, on such December 31, the price of the HCC
          Common Stock has increased since the previous January 1, by
          an amount that is greater than or equal to 25%; and

          An additional option to acquire an additional 5,000 shares
          for each additional 5% increase in the price of the HCC
          Common Stock since the previous January 1.

          Each of such options set forth in this Subparagraph (ii) shall be
          priced at the average of the closing prices of HCC shares for the
          month of December of the year of the grant and shall vest immediately.
          For purposes of this Subparagraph, the granting of any option shall
          not be pro-rated if the criteria set forth herein are not achieved in
          full.

          (d)  EXPENSES.  During the Basic Term, Executive shall be entitled 
to receive prompt reimbursement for all reasonable expenses incurred by him 
in accordance with the policies and procedures established by the 
Compensation Committee for the Company's senior executive officers in 
performing services hereunder, provided that Executive properly accounts

therefor in accordance with Company policy.

          (e)  OTHER BENEFITS.  Executive shall be entitled to participate in 
or receive benefits under any compensatory employee benefit plan or other 
arrangement made available by the Company now or in the future to its senior 
executive officers and key management employees, subject to and on a basis 
consistent with the terms, conditions, and overall administration of such 
plan or arrangement.  Nothing paid to Executive under any plan or arrangement 
presently in effect or made available in the future shall be deemed to be in 
lieu of the Base Salary payable to Executive pursuant to Paragraph (a) of 
this Section.  The Company shall not make any changes in any employee benefit 
plans or other arrangements in effect on the date hereof or subsequently in 
effect in which Executive currently or in the future participates (including, 
without limitation, each pension and retirement plan, supplemental pension 
and retirement plan, savings and profit sharing plan, stock or unit ownership 
plan, stock or unit purchase plan, stock or unit option plan, life insurance 
plan, medical insurance plan, disability plan, dental plan, health and 
accident plan, or any other similar plan or arrangement) that would adversely 
affect Executive's rights or benefits thereunder, unless such change occurs 
pursuant to a program applicable to substantially all executives of the 
Company and does not result in a proportionately greater reduction in the 
rights of or benefits to Executive as compared with any other executive of 
the Company.

          (f)  VACATIONS.  Executive shall be entitled to twenty-five (25) 
paid vacation days per year during the Basic Term.  There shall be no 
carryover of unused vacation from year to year.  For purposes of this 
Paragraph, weekends shall not count as vacation days, and Executive shall 
also be entitled to all paid holidays and personal days given by the Company 
to its senior executive officers.

          (g)  PERQUISITES.  Executive shall be entitled to receive the 
perquisites and fringe benefits appertaining to an executive officer of HCC 
in accordance with any practice established by the Compensation Committee. 
Notwithstanding, and in addition to, any perquisites to which Executive is 
entitled pursuant to the preceding sentence, Executive shall: (i) have use of 
a 1998 Mercedes 500 SEL automobile, and the Company shall pay all expenses 
related to Executive's use of such car, including gasoline, insurance, and 
maintenance; (ii) be allowed to travel on business utilizing first class 
passage (whether domestic or international); (iii) receive an annual country 
club dues allowance of up to $16,000; and (iv) receive a total of $1,000,000 
term life insurance (which shall be in addition to the standard benefits 
provided to Executive under the Company's group life insurance program that 
covers officers).

          (h)  PRORATION.  Any payments or benefits payable to Executive 
hereunder in respect of any calendar year during which Executive is employed 
by the Company for less than the entire year, unless otherwise provided in 
the applicable plan or arrangement, shall be prorated in accordance with the 
number of days in such calendar year during which he is so employed.  
Notwithstanding the foregoing, any payments pursuant to Paragraphs 4(c) or 
4(d) of this Agreement shall not be subject to proration.

     5.   TERMINATION.

          (a)  DEFINITIONS.

               (1)  "CAUSE" shall mean:

                    (i)   Material dishonesty which is not the result of an
     inadvertent or innocent mistake of Executive with respect to the Company or
     any of its subsidiaries;

                    (ii)  Willful misfeasance or nonfeasance of duty by
     Executive intended to injure or having the effect of injuring in some
     material fashion the reputation, business, or business relationships of the
     Company or any of its subsidiaries or any of their respective officers,
     directors, or employees;

                    (iii) Material violation by Executive of any material term
     of this Agreement; or

                    (iv)  Conviction of Executive of any felony, any crime
     involving moral turpitude or any crime other than a vehicular offense which
     could reflect in some material fashion unfavorably upon the Company or any
     of its subsidiaries.

Executive may not be terminated for Cause unless and until there has been 
delivered to Executive written notice from the Board supplying the 
particulars of Executive's acts or omissions that the Board believes 
constitute Cause, a reasonable period of time (not less than 30 days) has 
been given to Executive after such notice to either cure the same or to meet 
with the Board, with his attorney if so desired by Executive, and following 
which the Board by action of not less than two-thirds of its members 
furnishes to Executive a written resolution specifying in detail its findings 
that Executive has been terminated for Cause as of the date set forth in the 
notice to Executive.

               (2)  A "CHANGE OF CONTROL" shall be deemed to have occurred if:

                    (i)   Any "person" or "group" (within the meaning of
     Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934) other
     than a trustee or other fiduciary holding securities under an employee
     benefit plan of the Company becomes the "beneficial owner" (as defined in
     Rule 13d-3 under the Securities Exchange Act of 1934), directly or
     indirectly, of 50% or more of the Company's then outstanding voting common
     stock; or

                    (ii)  At any time during the period of three (3) consecutive
     years (not including any period prior to the date hereof), individuals who
     at the beginning of such period constituted the Board (and any new director
     whose election by the Board or whose nomination for election by the
     Company's shareholders were approved by a vote of at least two-thirds of
     the directors then still in office who either were directors at the

EMPLOYMENT AGREEMENT - Page 5
<PAGE>

     beginning of such period or whose election or nomination for election was
     previously so approved) cease for any reason to constitute a majority
     thereof; or

                    (iii) The shareholders of the Company approve a merger or
     consolidation of the Company with any other corporation, other than a
     merger or consolidation (a) in which a majority of the directors of the
     surviving entity were directors of the Company prior to such consolidation
     or merger, and (b) which would result in the voting securities of the
     Company outstanding immediately prior thereto continuing to represent
     (either by remaining outstanding or by being changed into voting securities
     of the surviving entity) more than 50% of the combined voting power of the
     voting securities of the surviving entity outstanding immediately after
     such merger or consolidation; or

                    (iv)  The shareholders approve a plan of complete
     liquidation of the Company or an agreement for the sale or disposition by
     the Company of all or substantially all of the Company's assets.

               (3)  A "DISABILITY" shall mean the absence of Executive from 
Executive's duties with the Company on a full-time basis for 180 consecutive 
days, or 180 days in a 365-day period, as a result of incapacity due to 
mental or physical illness which results in the Executive being unable to 
perform the essential functions of his position, with or without reasonable 
accommodation.

               (4)  A "GOOD REASON" shall mean any of the following (without 
Executive's express written consent):

                    (i)   Following a Change of Control, a material alteration
     in the nature or status of Executive's title, duties or responsibilities,
     or the assignment of duties or responsibilities inconsistent with
     Executive's status, title, duties and responsibilities; 

                    (ii)  A failure by the Company to continue in effect any
     employee benefit plan in which Executive was participating, or the taking
     of any action by the Company that would adversely affect Executive's
     participation in, or materially reduce Executive's benefits under, any such
     employee benefit plan, unless such failure or such taking of any action
     adversely affects the senior members of corporate management of the Company
     generally to the same extent;

                    (iii) A relocation of the Company's principal executive
     offices, or Executive's relocation to any place other than the principal
     executive offices, exceeding a distance of fifty (50) miles from the
     Company's current executive office located in Houston, Texas, except for
     reasonably required travel by Executive on the Company's business;

                    (iv)  Any material breach by the Company of any provision of

EMPLOYMENT AGREEMENT - Page 6
<PAGE>

     this Agreement including, without limitation, a failure to elect Executive
     the Chief Executive Officer of the Company on or before December 31, 1999;
     or

                    (v)   Any failure by the Company to obtain the assumption
     and performance of this Agreement by any successor (by merger,
     consolidation, or otherwise) or assign of the Company.

     However, Good Reason shall exist with respect to an above specified matter
     only if such matter is not corrected by the Company within thirty (30) days
     of its receipt of written notice of such matter from Executive, and in no
     event shall a termination by Executive occurring more than ninety (90) days
     following the date of the event described above be a termination for Good
     Reason due to such event.

               (5)  "TERMINATION DATE" shall mean the date Executive is 
terminated for any reason pursuant to this Agreement.

          (b)  TERMINATION WITHOUT CAUSE OR TERMINATION FOR GOOD REASON: 
BENEFITS.  In the event there is a termination by the Company without Cause, 
or if Executive terminates for Good Reason (a "Termination Event"), this 
Agreement shall terminate, except as provided in Paragraph 6, and Executive 
shall be entitled to the following severance benefits:

               (1)   For a period of twelve (12) months after the Termination
     Date (unless the remainder of the Basic Term is less than twelve
     (12) months in which case, for an amount of time equal to the remainder of
     the Basic Term), Base Salary (as defined in Paragraph 3(a)), at the rate,
     and payable quarterly unless such termination is by the Company without
     Cause, in which event such amount of Base Salary shall be paid in a lump
     sum within ten (10) days of the Termination Event.

               (2)  If there is a Change of Control or if there is a termination
     by the Company without Cause or by Executive for Good Reason, any stock
     options and other stock-related grants ("Stock Awards") which Executive has
     received under any of the HCC stock plans shall vest immediately; provided,
     however, that the right to receive options referenced in Paragraph 3(c)(2)
     above shall terminate upon termination from employment for any reason, and
     further, if there is a termination for Good Reason or by the Company other
     than for Cause, all options shall be exercisable for one year or the
     remainder of their term, whichever is less.

               (3)  To the extent not theretofore paid or provided, the Company
     shall timely pay or provide to Executive any other amounts or benefits
     required to be paid or provided or which Executive is eligible to receive
     under any plan, program, policy or practice, or contract or agreement of
     the Company and its affiliated companies for the period of time equal to
     the remainder of the Basic Term (such other amounts and benefits shall be
     hereinafter referred to as the "Other Benefits").  Without limiting the
     preceding sentence, through December 31, 2002 the Company, at its sole
     expense, shall continue to 

EMPLOYMENT AGREEMENT - Page 7
<PAGE>

     provide (through its own plan and/or individual policies) Executive (and 
     Executive's dependents) with health benefits no less favorable than the 
     group health plan benefits provided during such period to any senior 
     executive officer of the Company or any affiliated company (to the extent 
     any such coverage or benefits are taxable to Executive by reason of being 
     provided under a self-insured health plan of the Company or an affiliate, 
     the Company shall make Executive "whole" for the same on an after-tax 
     basis).  In any event, the Other Benefits provided for pursuant to this 
     Paragraph shall be secondary to any benefits and coverage Executive (or 
     his dependents) receive from another employer.

               (4)  If Executive receives any payments whether or not pursuant
     to this Agreement which are subject to an excise tax imposed under
     Section 4999 of the Internal Revenue Code of 1986, as amended, or any
     similar tax imposed under federal, state, or local law (collectively,
     "Excise Taxes"), the Company shall pay to Executive (on or before the date
     on which the Company is required to withhold such Excise Taxes), 1) an
     additional amount equal to all Excise Taxes then due and payable, and
     2) the amount necessary to defray Executive's increased (federal, state,
     and local) tax liability arising due to payment of the amount specified in
     this Subsection (4) which shall include any costs and expenses, including
     penalties and interest incurred by Executive in connection with any audit,
     proceedings, etc. related to the payment of such Excise Taxes or this
     payment.  For purposes of calculating the amount payable to Executive under
     this Paragraph, the federal and state income tax rates used shall be the
     highest marginal federal and state rates applicable to ordinary income in
     Executive's state of residence, taking into account any federal income tax
     deductions or credits available to Executive for state income taxes.  The
     Company shall cause its independent auditors to calculate such amount and
     provide Executive a copy of such calculation at least ten (10) days prior
     to the date specified above for payment of such amount.  It is the intent
     of the Parties that this Subsection (4) shall place Executive in the same
     net after-tax position Executive would have been in had no payment been
     subject to an Excise Tax and, notwithstanding anything herein to the
     contrary, it shall be construed to effectuate said result.

               (5)  All accrued compensation and unreimbursed expenses through
     the Termination Date.  Such amounts shall be paid to Executive in a lump
     sum in cash within thirty (30) days after the Termination Date; and

               (6)  Executive shall be free to accept other employment during
     such period, and there shall be no offset of any employment compensation
     earned by Executive in such other employment during such period against
     payments due Executive under this Paragraph (4), and there shall be not
     offset in any compensation received from such other employment against the
     Base Salary set forth above.

          (c)  TERMINATION IN EVENT OF DEATH:  BENEFITS.  If Executive's 
employment is terminated by reason of Executive's death during the Basic 
Term, this Agreement shall terminate, except as provided in Paragraph 6, 
without further obligation to Executive's legal representatives 

EMPLOYMENT AGREEMENT - Page 8
<PAGE>

under this Agreement, other than for payment of all accrued compensation, 
unreimbursed expenses, the timely payment or provision of Other Benefits 
through the date of death, and, if such death occurs on or after October 1 of 
any year, such cash or stock bonus as Executive would otherwise have been 
awarded in such year if Executive's death had not occurred.  Such amounts 
shall be paid to Executive's estate or beneficiary, as applicable, in a lump 
sum in cash within ninety (90) days after the date of death.  With respect to 
the provision of Other Benefits, the term Other Benefits as used in this 
Paragraph 4(c) shall include, without limitation, and Executive's estate 
and/or beneficiaries shall be entitled to receive, benefits at least equal to 
the most favorable benefits provided by the Company to the estates and 
beneficiaries of other executive level employees of the Company under such 
plans, programs, practices, and policies relating to death benefits, if any, 
as in effect with respect to other executives and their beneficiaries at any 
time during the 120-day period immediately preceding the date of death.  
Additionally, all Stock Awards for which Executive would have been eligible 
had he completed the Basic Term (except as set forth in Paragraph 4(b)(2)), 
shall be accelerated, and Executive's estate or beneficiary shall be vested 
in such Stock Awards as of the date of Executive's termination.

          (d)  TERMINATION IN EVENT OF DISABILITY:  BENEFITS.  If Executive's 
employment is terminated by reason of Executive's Disability during the Basic 
Term, this Agreement shall continue in full force for a period of one (1) 
year following such Disability and if such Disability occurs on or after 
October 1 of any year Executive shall be entitled to the same cash or stock 
bonus in such year that Executive would have been awarded if such Disability 
had not occurred. Following such one (1) year period, this Agreement shall 
continue in full force except that (a) the Base Salary shall be reduced by 
50% and (b) Executive shall not be entitled to any subsequent cash or stock 
bonuses.  In addition, all outstanding Stock Awards shall vest immediately 
upon such termination due to Disability.  If Executive's Disability occurs 
prior to the commencement of the Consulting Period, defined below, in 
addition to the amounts provided for herein, Executive shall receive the 
Consulting Fee, defined below, at such time as it would have otherwise been 
earned, whether or not Executive can perform Consulting Services, defined 
below.

          (e)  VOLUNTARY TERMINATION BY EMPLOYEE AND TERMINATION FOR CAUSE: 
BENEFITS.  Executive may terminate his employment with the Company without 
Good Reason by giving written notice of his intent and stating an effective 
Termination Date at least ninety (90) days after the date of such notice; 
provided, however, that the Company may accelerate such effective date by 
paying Executive through the proposed Termination Date and also vesting 
awards that would have vested but for this acceleration of the proposed 
Termination Date. Upon such a termination by Executive except as provided in 
Paragraph 6 or upon termination for Cause by the Company, this Agreement 
shall terminate and the Company shall pay to Executive all accrued 
compensation, unreimbursed expenses and the Other Benefits through the 
Termination Date.  Such amounts shall be paid to Executive in a lump sum in 
cash within thirty (30) days after the date of termination.

          (f)  DIRECTOR POSITIONS.  Executive agrees that upon termination of 
employment, for any reason, at the request of the Chairman of the Board, he 
will immediately 

EMPLOYMENT AGREEMENT - Page 9
<PAGE>

tender his resignation from any and all Board positions held with the Company 
and/or any of its subsidiaries and affiliates.  If Executive remains as a 
director, after such termination, Executive shall be compensated as an 
outside director.

     6.   NON-COMPETITION, NON-SOLICITATION, AND CONFIDENTIALITY.  Executive 
recognizes and agrees that the benefit of not being employed at-will, is 
provided in consideration for, among other things, the agreements contained 
in this Section, as well as the Stock Options granted to Executive pursuant 
to this Agreement.  The Company agrees that while employed pursuant to this 
Agreement, Executive will be provided with confidential information of 
Company; specialized training on how to perform his duties; and contact with 
the Company's customers and potential customers.  Furthermore, in the event 
Executive is terminated without Cause, or terminates for Good Reason, and 
more than one (1) year remains on the existing Basic Term, then Executive 
shall receive additional consideration in an amount equal to the quotient of 
the Base Salary divided by 12, which shall thereupon be multiplied by the 
number of months remaining in the Basic Term minus 12 months and which shall 
be paid in one lump sum within ten (10) days of such termination.

     In consideration of all of the foregoing, Executive agrees as follows:

          (a)  NON-COMPETITION DURING EMPLOYMENT.  Executive agrees during 
the Basic Term he will not compete with the Company by engaging in the 
conception, design, development, production, marketing, or servicing of any 
product or service that is substantially similar to the products or services 
which the Company provides, and that he will not work for, in any capacity, 
assist, or become affiliated with as an owner, partner, etc., either directly 
or indirectly, any individual or business which offers or performs services, 
or offers or provides products substantially similar to the services and 
products provided by Company.

          (b)  CONFLICTS OF INTEREST.  Executive agrees that during the Basis 
Term, he will not engage, either directly or indirectly, in any activity (a 
"Conflict of Interest") which might adversely affect the Company or its 
affiliates, including ownership of a material interest in any supplier, 
contractor, distributor, subcontractor, customer or other entity with which 
the Company does business or accepting any material payment, service, loan, 
gift, trip, entertainment, or other favor from a supplier, contractor, 
distributor, subcontractor, customer or other entity with which the Company 
does business, and that Executive will promptly inform the Chairman of the 
Company as to each offer received by Executive to engage in any such 
activity.  Executive further agrees to disclose to the Company any other 
facts of which Executive becomes aware which might in Executive's good faith 
judgment reasonably be expected to involve or give rise to a Conflict of 
Interest or potential Conflict of Interest.

          (c)  NON-COMPETITION AFTER TERMINATION.  Executive agrees that 
Executive shall not, at any time during the period of two (2) years after the 
termination of the Basic Term, for any reason, within any of the markets in 
which the Company has sold products or services or formulated a plan to sell 
products or services into a market during the last twelve (12) months of 
Executive's employ or which the Company enters into within three (3) months 
thereafter, engage 

EMPLOYMENT AGREEMENT - Page 10
<PAGE>

in or contribute Executive's knowledge to any work which is competitive with 
or similar to a product, process, apparatus, service, or development on which 
Executive worked or with respect to which Executive had access to 
Confidential Information while employed by the Company; provided, however, 
this Paragraph (c) shall not operate to prevent Executive from engaging in 
retail insurance or re-insurance activities during such two-year period to 
the extent such activities do not compete or permit any other person or 
entity to compete with any business the Company or any of its subsidiaries or 
affiliated companies were engaged in at the time of such termination or which 
the Company enters into within three (3) months thereafter.  Following the 
expiration of said two (2) year period, Executive shall continue to be 
obligated under the Confidential Information Paragraph of this Agreement not 
to use or to disclose Confidential Information of the Company so long as it 
shall not be publicly available.  It is understood that the geographical area 
set forth in this covenant is divisible so that if this clause is invalid or 
unenforceable in an included geographic area, that area is severable and the 
clause remains in effect for the remaining included geographic areas in which 
the clause is valid.

          (d)  NON-SOLICITATION OF CUSTOMERS.  Executive further agrees that 
for a period of two (2) years after the termination of the Basic Term, he 
will not solicit or accept any business from any customer or client or 
prospective customer or client with whom Executive dealt or solicited while 
employed by Company during the last twelve (12) months of his employment.

          (e)  NON-SOLICITATION OF EMPLOYEES.  Executive agrees that for the 
duration of the Basic Term, and for a period of two (2) years after the 
termination of the Basic Term, he will not either directly or indirectly, on 
his own behalf or on behalf of others, solicit, attempt to hire, or hire any 
person employed by Company to work for Executive or for another entity, firm, 
corporation, or individual.

          (f)  CONFIDENTIAL INFORMATION.  Executive further agrees that he 
will not, except as the Company may otherwise consent or direct in writing, 
reveal or disclose, sell, use, lecture upon, publish or otherwise disclose to 
any third party any Confidential Information or proprietary information of 
the Company, or authorize anyone else to do these things at any time either 
during or subsequent to his employment with the Company.  This Section shall 
continue in full force and effect after termination of Executive's employment 
and after the termination of this Agreement.  Executive's obligations under 
this Paragraph with respect to any specific Confidential Information and 
proprietary information shall cease when that specific portion of the 
Confidential Information and proprietary information becomes publicly known, 
in its entirety and without combining portions of such information obtained 
separately.  It is understood that such Confidential Information and 
proprietary information of the Company include matters that Executive 
conceives or develops, as well as matters Executive learns from other 
employees of Company.  Confidential Information is defined to include 
information:  (1) disclosed to or known by the Executive as a consequence of 
or through his employment with the Company; (2) not generally known outside 
the Company; and (3) which relates to any aspect of the Company or its 
business, finances, operation plans, budgets, research, or strategic 
development.  "Confidential Information" includes, but is not limited to the 
Company's trade secrets, proprietary information, 

EMPLOYMENT AGREEMENT - Page 11
<PAGE>

financial documents, long range plans, customer lists, employer compensation, 
marketing strategy, data bases, costing data, computer software developed by 
the Company, investments made by the Company, and any information provided to 
the Company by a third party under restrictions against disclosure or use by 
the Company or others.

          (g)  RETURN OF DOCUMENTS, EQUIPMENT, ETC.  All writings, records, 
and other documents and things comprising, containing, describing, 
discussing, explaining, or evidencing any Confidential Information, and all 
equipment, components, parts, tools, and the like in Executive's custody or 
possession that have been obtained or prepared in the course of Executive's 
employment with the Company shall be the exclusive property of the Company, 
shall not be copied and/or removed from the premises of the Company, except 
in pursuit of the business of the Company, and shall be delivered to the 
Company, without Executive retaining any copies, upon notification of the 
termination of Executive's employment or at any other time requested by the 
Company.  The Company shall have the right to retain, access, and inspect all 
property of Executive of any kind in the office, work area, and on the 
premises of the Company upon termination of Executive's employment and at any 
time during employment by the Company to ensure compliance with the terms of 
this Agreement.

          (h)  REAFFIRM OBLIGATIONS.  Upon termination of his employment with 
the Company, Executive, if requested by Company, shall reaffirm in writing 
Executive's recognition of the importance of maintaining the confidentiality 
of the Company's Confidential Information and proprietary information, and 
reaffirm any other obligations set forth in this Agreement.

          (i)  PRIOR DISCLOSURE.  Executive represents and warrants that he 
has not used or disclosed any Confidential Information he may have obtained 
from Company prior to signing this Agreement, in any way inconsistent with 
the provisions of this Agreement.

          (j)  CONFIDENTIAL INFORMATION OF PRIOR COMPANIES.  Executive will 
not disclose or use during the period of his employment with the Company any 
proprietary or Confidential Information or Copyright Works which Executive 
may have acquired because of employment with an employer other than the 
Company or acquired from any other third party, whether such information is 
in Executive's memory or embodied in a writing or other physical form.

          (k)  BREACH.  Executive agrees that any breach of Paragraphs 5(a), 
(c), (d), (e) or (f) above cannot be remedied solely by money damages, and 
that in addition to any other remedies Company may have, Company is entitled 
to obtain injunctive relief against Executive.  Nothing herein, however, 
shall be construed as limiting Company's right to pursue any other available 
remedy at law or in equity, including recovery of damages and termination of 
this Agreement and/or any payments that may be due pursuant to this Agreement.

          (l)  RIGHT TO ENTER AGREEMENT.  Executive represents and covenants 
to Company that he has full power and authority to enter into this Agreement 
and that the execution of this Agreement will not breach or constitute a 
default of any other agreement or contract to 

EMPLOYMENT AGREEMENT - Page 12
<PAGE>

which he is a party or by which he is bound.

          (m)  EXTENSION OF POST-EMPLOYMENT RESTRICTIONS.  In the event 
Executive breaches Paragraphs 5(b), (d), or (e) above, the restrictive time 
periods contained in those provisions will be extended by the period of time 
Executive was in violation of such provisions.

          (n)  ENFORCEABILITY.  The agreements contained in Section 5 are 
independent of the other agreements contained herein.  Accordingly, failure 
of the Company to comply with any of its obligations outside of this 
Paragraph do not excuse Executive from complying with the agreements 
contained herein.

          (o)  SURVIVABILITY.  The agreements contained in Paragraphs 
5(c)-(g) shall survive the termination of this Agreement for any reason.

     7.   CONSULTING AGREEMENT. Effective upon Executive's termination of 
employment for any reason other than Executive's termination prior to the end 
of the Basic Term by the Company for Cause, HCC hereby retains Executive as a 
consultant (an independent contractor and not as an employee) for a period of 
ten (10) years (the "Consulting Period").  Termination of the Basic Term 
shall not effect the Parties' rights and obligations under this Paragraph 6.  
Subject to the following, Executive agrees to provide, if requested, a 
minimum of 200 hours of service per year, or, as requested by the Company, up 
to a total of 600 hours during any one year of the Consulting Period; 
provided, however, that the total number of hours to be worked over the 
duration of the Consulting Period shall not exceed 2,000 (the "Consulting 
Services").  The Consulting Services to be provided shall be commensurate 
with Executive's training, background, experience and prior duties with the 
Company.  Executive agrees to make himself reasonably available to provide 
such Consulting Services during the Consulting Period; provided, however, the 
Company agrees that it shall provide reasonable advance notice to Executive 
of its expected consulting needs and any request for Consulting Services 
hereunder shall not unreasonably interfere with Executive's other business 
activities and personal affairs as determined in good faith by Executive.  In 
addition, Executive shall not be required to perform any requested Consulting 
Services which, in Executive's good faith opinion, would cause Executive to 
breach any fiduciary duty or contractual obligation Executive may have to 
another employer.  Further, during the Consulting Period, Executive shall not 
be subject to any non-competition provisions except for the two-year period 
provided for in Paragraph 5(c).  Unless waived by Executive, Executive shall 
not be required to perform Consulting Services for more than four (4) days 
during any week or for more than eight (8) hours during any day.  Executive's 
travel time shall constitute hours of Consulting Services for purposes of 
this Paragraph 6.  The Parties contemplate that, when appropriate, the 
Consulting Services shall be performed at Executive's office, residence or at 
the Company's executive offices in Houston, Texas and may be performed  at 
such other locations only as they may mutually agree upon.  Executive shall 
be properly reimbursed for all travel and other expenses reasonably incurred 
by Executive in rendering the  Consulting Services.  HCC shall pay Executive 
$100,000 per year (the "Consulting Fee") during the Consulting Period, 
payable monthly in arrears. Executive may elect to delay payment for services 
but not the services themselves.  Except as set forth below 

EMPLOYMENT AGREEMENT - Page 13
<PAGE>

and in Paragraphs 4(c) or 4(d) hereof, if Executive fails to provide the 
hours requested by the Company in any 24-month period, Executive's rights to 
receive any further Consulting Fee shall immediately terminate.  During the 
Consulting Period, Executive shall receive no employment benefits from HCC.  
If Executive dies or becomes Disabled during the Basic Term (or as an 
employee of the Company following the Basic Term) or during the Consulting 
Period he (or, on his death, his beneficiary or estate) shall receive or 
continue to receive as the case may be the Consulting Fee during the 
remainder of the Consulting Period as if such death or Disability had not 
occurred.  

     8.   ASSIGNMENT.  This Agreement cannot be assigned by Executive.  The 
Company may assign this Agreement only to a successor (whether direct or 
indirect, by purchase, merger, consolidation or otherwise) to all or 
substantially all of the business and assets of the Company provided such 
successor expressly agrees in writing reasonably satisfactory to Executive to 
assume and 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 and 
assignment had taken place.  Failure of the Company to obtain such written 
agreement prior to the effectiveness of any such succession shall be a 
material breach of this Agreement.

     9.   BINDING AGREEMENT.  Executive understands that his obligations 
under this Agreement are binding upon Executive's heirs, successors, personal 
representatives, and legal representatives.

     10.  NOTICES.  All notices pursuant to this Agreement shall be in 
writing and sent certified mail, return receipt requested, addressed as set 
forth below, or by delivering the same in person to such party, or by 
transmission by facsimile to the number set forth below.  Notice deposited in 
the United States Mail, mailed in the manner described hereinabove, shall be

     11.  WAIVER.  No waiver by either party to this Agreement of any right 
to enforce any term or condition of this Agreement, or of any breach hereof, 
shall be deemed a waiver of such right in the future or of any other right or 
remedy available under this Agreement.

     12.  SEVERABILITY.  If any provision of this Agreement is determined to 
be void, invalid, unenforceable, or against public policy, such provisions 
shall be deemed severable from the Agreement, and the remaining provisions of 
the Agreement will remain unaffected and in full force and effect.

     13.  ARBITRATION.  In the event any dispute arises out of Executive's 
employment with or by the Company, or separation/termination therefrom, 
whether as an employee or as a consultant, which cannot be resolved by the 
Parties to this Agreement, such dispute shall be submitted to final and 
binding arbitration.  The arbitration shall be conducted in accordance with 
the National Rules for the Resolution of Employment Disputes of the American 
Arbitration Association ("AAA").  If the Parties cannot agree on an 
arbitrator, a list of seven (7) arbitrators will be requested from AAA, and 
the arbitrator will be selected using alternate strikes with Executive 
striking first.  The cost of the arbitration will be shared equally by 
Executive and Company; provided, however, the Company shall promptly 
reimburse Executive for all costs and expenses incurred in connection with 
any dispute in an amount up to, but not exceeding 20 percent of Executive's 
Base Salary (or, if the dispute arises during the Consulting Period, 
Executive's Base Salary as in effect immediately prior to the beginning of 
the Consulting Period) unless such termination was for Cause in which event 
Executive shall not be entitled to reimbursement unless and until it is 
determined he was terminated other than for Cause.  Arbitration of such 
disputes is mandatory and in lieu of any and all civil causes of action and 
lawsuits either party may have against the other arising out of Executive's 
employment with Company, or separation therefrom.  Such arbitration shall be 
held in Houston, Texas.

     14.  ENTIRE AGREEMENT.  The terms and provisions contained herein shall 
constitute the entire agreement between the parties with respect to 
Executive's employment with Company during the time period covered by this 
Agreement.  This Agreement replaces and supersedes any and all existing 
Agreements entered into between Executive and the Company relating generally 
to the same subject matter, if any, and shall be binding upon Executive's 
heirs, executors, administrators, or other legal representatives or assigns.

     15.  MODIFICATION OF AGREEMENT.  This Agreement may not be changed or 
modified or released or discharged or abandoned or otherwise terminated, in 
whole or in part, except by an instrument in writing signed by the Executive 
and an officer or other authorized executive of Company.

     16.  UNDERSTAND AGREEMENT.  Executive represents and warrants that he 
has read and understood each and every provision of this Agreement, and 
Executive understands that he has the right to obtain advice from legal 
counsel of choice, if necessary and desired, in order to interpret any and 
all provisions of this Agreement, and that Executive has freely and 
voluntarily entered into this Agreement.

     17.  GOVERNING LAW.  This Agreement shall be governed by and construed 
in accordance with the laws of the State of Texas.

     18.  JURISDICTION AND VENUE.  With respect to any litigation regarding 
this Agreement, Executive agrees to venue in the state or federal courts in

                              EMPLOYMENT AGREEMENT

     This Employment Agreement ("Agreement") is entered into effective as of 
the 1st day of January, 1998 (the "Effective Date"), between HCC INSURANCE 
HOLDINGS, INC. ("HCC" or the "Company"), and STEPHEN J. LOCKWOOD 
("Executive"), sometimes collectively referred to herein as the "Parties".

                                R E C I T A L S:

     WHEREAS, Executive is to be employed as Vice Chairman of the Board of 
Directors of HCC and Chairman and Chief Executive Officer of LDG Reinsurance 
Corporation ("LDG"); and

     WHEREAS, it is the desire of the Board of Directors of HCC (the "Board") 
to directly engage Executive in the capacities set forth above; and

     WHEREAS, Executive is desirous of committing himself to serve HCC on the 
terms herein provided.

     NOW, THEREFORE, in consideration of the foregoing and of the respective 
covenants and agreements set forth below, the Parties agree as follows:

     2.   TERM.  The Company hereby agrees to employ Executive as its Vice 
Chairman of the Board of Directors, as the Chairman and Chief Executive 
Officer of LDG and as a director of HCC Benefits, Inc. ("Benefits"), and 
Executive hereby agrees to accept such employment, on the terms and 
conditions set forth herein, for the period commencing on the Effective Date 
and expiring as of 11:59 p.m. on December 31, 2002 (the "Basic Term") (unless 
sooner terminated as hereinafter set forth).  At any time on or after January 
1, 2000, and prior to December 31, 2002, Executive may, at his option, cease 
to be a full time employee and elect to begin the Consulting Period as 
defined in Section 6 hereof.  (The period of time beginning as of the date 
Executive commences the Consulting Period, if before December 31, 2002, and 
ending on December 31, 2002 is hereinafter called the "Early Consulting 
Period").

     3.   DUTIES.

          (a)  DUTIES AS EMPLOYEE OF THE COMPANY.  Executive shall, subject 
to the supervision of the Board act as Vice Chairman of the Board of HCC, 
Chairman and Chief Executive Officer of LDG, and a director of Benefits in 
the ordinary course of its business with all such powers as may be reasonably 
incident to such responsibilities.  Executive shall report to the Chairman of 
the Board or the President of HCC.  During normal business hours Executive 
shall devote his full time and attention to diligently attending to the 
business of the Company and its subsidiaries during his term of employment 
hereunder.  During his term of employment, Executive shall not directly or 
indirectly render any services of a business, commercial, or 

EMPLOYMENT AGREEMENT - Page 1
<PAGE>

professional nature to any other person, firm, corporation, or organization, 
whether for compensation or otherwise, without the prior written consent of 
the Board.  However, Executive shall have the right to engage in such 
activities as may be appropriate in order to manage his personal investments 
so long as such activities do not interfere or conflict with the performance 
of his duties to the Company and its subsidiaries as set forth hereunder.  
The conduct of such activity shall not be deemed to materially interfere or 
conflict with Executive's performance of his duties until Executive has been 
notified in writing thereof and given a reasonable period in which to cure 
the same. 

          (b)  OTHER DUTIES.  At all times during the Basic Term, the Company 
shall use its best efforts to cause Executive to be elected director and to 
serve on the Senior Management Committee of HCC.  If elected, Executive 
agrees that he shall not be entitled to receive any compensation for serving 
as a Director of HCC or any of HCC's subsidiaries other than the compensation 
to be paid to Executive by the Company pursuant to this Agreement.

     4.   COMPENSATION AND RELATED MATTERS.  

          (a)  BASE SALARY.  Executive shall receive an initial base salary 
paid by the Company at the annual rate of $450,000, during 1998 and 1999.  
Subject to Executive's right to begin the Consulting Period, as set forth in 
Section 6, if Executive no longer acts as the Chief Executive Officer of LDG 
such base salary shall be reduced to $100,000 beginning January 1, 2000  or 
such later date as Executive ceases to act as Chief Executive Officer of LDG 
and shall remain at $100,000 during the remainder of the Basic Term.  All 
base salary payments shall be payable in substantially equal monthly 
installments.  For purposes of this Agreement, "Base Salary" shall mean the 
Executive's initial base salary and, when changed, the changed base salary.

          (b)  BONUS PAYMENTS.  Executive shall be eligible to receive, in 
addition to the Base Salary, an annual cash bonus payment in an amount, which 
may be zero, to be determined in the sole discretion of the Company's 
Compensation Committee.

          (c)  STOCK OPTIONS.  In addition to stock options previously 
granted to Executive, in partial consideration for Executive's 
non-competition agreements, set forth herein, Executive shall be provided 
with additional options to purchase HCC shares as follows:

          (1)  150,000 shares to be granted effective as of January 7,
               1998, at an exercise price of $16.50 per share vesting in
               two equal installments of 75,000 shares on December 31, 1998
               and December 31, 1999;

          (2)  50,000 shares on December 31 of each year during the Basic
               Term if, but only if, Executive is maintaining the position
               of Chief Executive Officer of LDG and if not maintaining
               such position on such date such option shall be reduced to
               25,000 options if, but only if, Executive is acting as
               Chairman of LDG.  Such options 

EMPLOYMENT AGREEMENT - Page 2
<PAGE>

               shall be priced at the average closing price of HCC shares 
               for the month of December of the year of the grant.  Any option 
               so granted shall vest immediately.

          (d)  EXPENSES.  During the Basic Term Executive shall be entitled 
to receive prompt reimbursement for all reasonable expenses incurred by him 
(in accordance with the policies and procedures established by the Board for 
its senior executive officers) in performing services hereunder, provided 
that Executive properly accounts therefor in accordance with Company policy 
and such expenses are approved by the Chairman of the Board or President of 
HCC.

          (e)  OTHER BENEFITS.  Executive shall be entitled to participate in 
or receive benefits under any employee benefit plan or other arrangement made 
available by the Company now or in the future to its senior executive 
officers and key management employees, subject to and on a basis consistent 
with the terms, conditions, and overall administration of such plan or 
arrangement. Nothing paid to Executive under any plan or arrangement 
presently in effect or made available in the future shall be deemed to be in 
lieu of the Base Salary payable to Executive pursuant to subsection (a) of 
this Section.  The Company shall not make any changes in any employee benefit 
plans or other arrangements in effect on the date hereof or subsequently in 
effect in which Executive currently or in the future participates (including, 
without limitation, each pension and retirement plan, supplemental pension 
and retirement plan, savings and profit sharing plan, stock or unit ownership 
plan, stock or unit purchase plan, stock or unit option plan, life insurance 
plan, medical insurance plan, disability plan, dental plan, health and 
accident plan, or any other similar plan or arrangement) that would adversely 
affect Executive's rights or benefits thereunder, unless such change occurs 
pursuant to a program applicable to substantially all executives of the 
Company and does not result in a proportionately greater reduction in the 
rights of or benefits to Executive as compared with any other executive of 
the Company.

          (f)  VACATIONS.  Executive shall be entitled to fifty (50) paid 
vacation days per year for each of the calendar years ended December 31 of 
the Basic Term while Executive is a full-time Employee.  There shall be no 
carryover of unused vacation from year to year.  For purposes of this 
Section, weekends shall not count as vacation days, and Executive shall also 
be entitled to all paid holidays given by the Company to its senior executive 
officers.

          (g)  PERQUISITES.  Executive shall be entitled to receive the 
perquisites and fringe benefits appertaining to an executive officer of HCC 
in accordance with any practice established by the Company's Compensation 
Committee.  Notwithstanding, and in addition to, any perquisites to which 
Executive is entitled pursuant to the preceding sentence, Executive shall: 
(i) have use of a Mercedes 500 SEL automobile, and the Company shall pay all 
expenses related to Executive's use of such car, including gasoline, 
insurance, and maintenance; and (ii) be allowed to travel on business 
utilizing: (x) First Class Domestic and International passage plus (y) for so 
long as Executive remains as Chief Executive Officer or Chairman of the Board 
of LDG, up to $3,000,000 of corporate aircraft expense (not to exceed 
$650,000 in each of the calendar years ending December 31, 1998 and 1999 and 
$575,000 in each of the calendar years 

EMPLOYMENT AGREEMENT - Page 3
<PAGE>

ending December 31, 2000 and 2001 and $550,000 in the calendar year ending 
December 31, 2002).  To avoid confusion, Executive's use of the corporate 
aircraft shall terminate if Executive ceases to be both Chief Executive 
Officer and the Chairman of the Board of LDG but not if he ceases to hold 
only one of such positions while retaining the other.  In addition, 
Executive's right to use corporate aircraft shall immediately terminate upon 
Executive's death or termination for Cause, whether during the Basic Term, 
the Early Consulting Period, or the Consulting Period.  From and after the 
Effective Date, Executive shall be entitled to utilization of an office and 
employees (whose compensation will not exceed $75,000 per year).  

          (h)  PRORATION.  Any payments or benefits payable to Executive 
hereunder in respect of any calendar year during which Executive is employed 
by the Company for less than the entire year, unless otherwise provided in 
the applicable plan or arrangement, shall be prorated in accordance with the 
number of days in such calendar year during which he is so employed.

     5.   TERMINATION.

          (a)  DEFINITIONS.

               (1)  "CAUSE" shall mean:

                    (i)   Material dishonesty which is not the result of an
     inadvertent or innocent mistake of Executive with respect to the Company or
     any of its subsidiaries;

                    (ii)  Willful misfeasance or nonfeasance of duty by
     Executive intended to injure or having the effect of injuring in some
     material fashion the reputation, business, or business relationships of the
     Company or any of its subsidiaries or any of their respective officers,
     directors, or employees;

                    (iii) Material violation by Executive of any term of this
     Agreement; or

                    (iv)  Conviction of Executive of any felony, any crime
     involving moral turpitude or any crime other than a vehicular offense which
     could reflect in some material fashion unfavorably upon the Company or any
     of its subsidiaries.

     Executive may not be terminated for Cause unless and until there has 
been delivered to Executive written notice from the Board supplying the 
particulars of Executive's acts or omissions that the Board believes 
constitutes Cause, a reasonable period of time (not less than 30 days) has 
been given to Executive after such notice to either cure the same or to meet 
with Board with his attorney if so desired by Executive, and following which 
the Board by action of not less than two-thirds (2/3rd) of its members 
furnishes to Executive a written resolution specifying in detail with 
findings that Executive has been terminated for Cause as of the date set 
forth in the notice to Executive.  

               (2)  A "CHANGE OF CONTROL" shall be deemed to have occurred if:

EMPLOYMENT AGREEMENT - Page 4
<PAGE>

                    (i)   Any "person" or "group" (within the meaning of
     Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934) other
     than a trustee or other fiduciary holding securities under an employee
     benefit plan of the Company becomes the "beneficial owner" (as defined in
     Rule 13d-3 under the Securities Exchange Act of 1934), directly or
     indirectly, of 50% or more of the Company's then outstanding voting common
     stock; or

                    (ii)  At any time during the period of three (3) consecutive
     years (not including any period prior to the date hereof), individuals who
     at the beginning of such period constituted the Board (and any new director
     whose election by the Board or whose nomination for election by the
     Company's shareholders were approved by a vote of at least two-thirds of
     the directors then still in office who either were directors at the
     beginning of such period or whose election or nomination for election was
     previously so approved) cease for any reason to constitute a majority
     thereof; or

                    (iii) The shareholders of the Company approve a merger or
     consolidation of the Company with any other corporation, other than a
     merger or consolidation (a) in which a majority of the directors of the
     surviving entity were directors of the Company prior to such consolidation
     or merger, and (b) which would result in the voting securities of the
     Company outstanding immediately prior thereto continuing to represent
     (either by remaining outstanding or by being changed into voting securities
     of the surviving entity) more than 50% of the combined voting power of the
     voting securities of the surviving entity outstanding immediately after
     such merger or consolidation; or

                    (iv)  The shareholders approve a plan of complete
     liquidation of the Company or an agreement for the sale or disposition by
     the Company of all or substantially all of the Company's assets.

               (3)  A "DISABILITY" shall mean the absence of Executive from 
Executive's duties with the Company on a full-time basis for 180 consecutive 
days, or 180 days in a 365-day period, as a result of incapacity due to 
mental or physical illness which results in the Executive being unable to 
perform the essential functions of his position, with or without reasonable 
accommodation.

               (4)  A "GOOD REASON" shall mean any of the following (without 
Executive's express written consent):

                    (i)   Following a Change of Control, a material alteration
     in the nature or status of Executive's title, duties or responsibilities,
     or the assignment of duties inconsistent with, or a substantial and
     material alteration in the nature or status of, Executive's duties and
     responsibilities;

EMPLOYMENT AGREEMENT - Page 5
<PAGE>

                    (ii)  A failure by the Company to continue in effect any
     employee benefit plan in which Executive was participating, or the taking
     of any action by the Company that would adversely affect Executive's
     participation in, or materially reduce Executive's benefits under, any such
     employee benefit plan, unless such failure or such taking of any action
     adversely affects the senior members of corporate management of the Company
     generally to the same extent;

                    (iii) Executive's required relocation to any place other
     than his current office exceeding a distance of one hundred (100) miles
     from Wakefield, Massachusetts, except for reasonably required travel by
     Executive on the Company's business;

                    (iv)  Any material breach by the Company of any provision of
     this Agreement if such material breach has not been cured within thirty
     (30) days following written notice of such breach by Executive to the
     Company setting forth with reasonable specificity the nature of the breach;
     or

                    (v)   Any failure by the Company to obtain the assumption
     and performance of this Agreement by any successor (by merger,
     consolidation, or otherwise) or assign of the Company.

     However, Good Reason shall exist with respect to an above-specified 
matter only if such matter is not corrected by the Company within thirty (30) 
days of its receipt of written notice of such matter from Executive, and in 
no event shall a termination by Executive occurring more than ninety (90) 
days following the date of the event described above be a termination for 
Good Reason due to such event. 

               (5)  "TERMINATION DATE" shall mean the date Executive is 
terminated for any reason pursuant to this Agreement.

          (b)  TERMINATION WITHOUT CAUSE OR TERMINATION FOR GOOD REASON: 
BENEFITS.  In the event there is a termination without Cause or if Executive 
terminates for Good Reason (a "Termination Event"), this Agreement shall 
terminate and Executive shall be entitled to the following severance benefits:

               (1)  For a period of twelve (12) months after the Termination
     Event (unless the remainder of the Basic Term is less than 12 months in
     which case, for an amount of time equal to the remainder of the Basic
     Term), Base Salary (as defined in Section 3(a), at the rate in effect
     immediately prior to the Termination Event, payable quarterly, in arrears.

               (2)  Subject to any contrary provisions of any stock option grant
     or plan that might provide for acceleration of vesting of options at an
     earlier date than set forth herein, if there is a Change of Control or if
     there is a termination without Cause, any 

EMPLOYMENT AGREEMENT - Page 6
<PAGE>

     stock options which Executive has received under the HCC Stock Option Plans
     shall vest immediately; provided, however, that the right to receive 
     options referenced in Section 3(c)(2) above shall terminate upon 
     termination from employment for any reason, and further, if there is a 
     termination for Good Reason, all unvested options shall be void.

               (3)  To the extent not theretofore paid or provided, the Company
     shall timely pay or provide to Executive any other amounts or benefits
     required to be paid or provided or which Executive is eligible to receive
     under any plan, program, policy or practice, or contract or agreement of
     the Company and its affiliated companies (such other amounts and benefits
     shall be hereinafter referred to as the "Other Benefits").  Without
     limiting the preceding sentence, through December 31, 2002, the Company, at
     its sole expense, shall continue to provide (through its own plan and/or
     individual policies) Executive (and Executive's dependents) with health
     benefits no less favorable than the group health plan benefits provided
     during such period to any senior executive officer in the Company or any
     affiliated company (to the extent any such coverage or benefits are taxable
     to Executive by reason of being provided under a self-insured health plan
     of the Company or an affiliate, the Company shall make Executive "whole"
     for the same on an after-tax basis.)  In any event the Other Benefits
     provided for pursuant to this Section shall be secondary to any benefits
     and coverage Executive (or his dependents) receive from another employer.

               (4)  If Executive receives any payments whether or not pursuant
     to this Agreement which are subject to an excise tax imposed under
     Section 4999 of the Internal Revenue Code of 1986, as amended, or any
     similar tax imposed under federal, state, or local law (collectively,
     "Excise Taxes"), the Company shall pay to Executive (on or before the date
     on which the Company is required to withhold such Excise Taxes), 1) an
     additional amount equal to all Excise Taxes then due and payable, and
     2) the amount necessary to defray Executive's increased (federal, state,
     and local) tax liability arising due to payment of the amount specified in
     this subsection (b)(4) which shall include any costs and expenses,
     including penalties and interest incurred by Executive in connection with
     any audit, proceedings, etc. related to the payment of such Excise Taxes or
     this payment.  For purposes of calculating the amount payable to Executive
     under this Section, the federal and state income tax rates used shall be
     the highest marginal federal and state rates applicable to ordinary income
     in Executive's state of residence, taking into account any federal income
     tax deductions or credits available to Executive for state income taxes. 
     The Company shall cause its independent auditors to calculate such amount
     and provide Executive a copy of such calculation at least ten (10) days
     prior to the date specified above for payment of such amount.  It is the
     intent of the Parties that this subsection (b)(4) shall place Executive in
     the same net after-tax position Executive would have been in had no payment
     been subject to an Excise Tax and, notwithstanding anything herein to the
     contrary, it shall be construed to effectuate said result;

               (5)  All accrued compensation and unreimbursed expenses through
     the Termination Date.  Such amounts shall be paid to Executive in a lump
     sum in cash within 

EMPLOYMENT AGREEMENT - Page 7
<PAGE>

     thirty (30) days after the Termination Date; and

               (6)  Executive shall be free to accept other employment during
     such period, and there shall be no offset of any employment compensation
     earned by Executive in such other employment during such period against
     payments due Executive hereunder, and there shall be not offset in any
     compensation received from such other employment against the Base Salary
     set forth above; provided, however, that such compensation may terminate if
     acceptance of such employment would violate any of the provisions of
     Section 5, below

     If Executive's employment is terminated pursuant to this subsection (b) 
on or after October 1 of any year, any cash or stock bonus which Executive 
would otherwise have been awarded in such year shall be awarded as if 
termination had not taken place. 

          (c)  TERMINATION IN EVENT OF DEATH:  BENEFITS.  If Executive's 
employment is terminated by reason of Executive's death during the Basic 
Term, this Agreement shall terminate without further obligation to 
Executive's legal representatives under this Agreement, other than for 
payment of all accrued compensation, unreimbursed expenses, the timely 
payment or provision of Other Benefits through the date of death, and, if 
such death occurs on or after October 1 of any year, such cash or stock bonus 
as Executive would otherwise have been awarded in such year if Executive's 
death had not occurred.  Such amounts shall be paid to Executive's estate or 
beneficiary, as applicable, in a lump sum in cash within ninety (90) days 
after the date of death.  With respect to the provision of Other Benefits, 
the term Other Benefits as used in this Section 4(c) shall include, without 
limitation, and Executive's estate and/or beneficiaries shall be entitled to 
receive, benefits at least equal to the most favorable benefits provided by 
the Company to the estates and beneficiaries of other executive level 
employees of the Company under such plans, programs, practices, and policies 
relating to death benefits, if any, as in effect with respect to other 
executives and their beneficiaries at any time during the 120-day period 
immediately preceding the date of death.  Additionally, all stock options for 
which Executive would have been eligible had he completed the Basic Term 
(except as set forth in Section 4(b)(2), shall be accelerated, and 
Executive's estate or beneficiary shall be vested in such options as of the 
date of Executive's termination.

          (d)  TERMINATION IN EVENT OF DISABILITY:  BENEFITS.  If Executive's 
employment is terminated by reason of Executive's Disability during the Basic 
Term, this Agreement shall continue in full force for a period of one (1) 
year following such Disability and if such Disability occurs on or after 
October 1 of any year Executive shall be entitled to the same cash or stock 
bonus in such year that Executive would have been awarded if such Disability 
had not occurred. Following such one (1) year period, this Agreement shall 
continue in full force for the remainder of the Basic Term except that (a) 
the Base Salary shall be reduced by 50% and (b) Executive shall, not be 
entitled to any subsequent cash or stock bonuses.  In addition, all 
outstanding options shall vest immediately upon the date of such Disability.  

         (e)  VOLUNTARY TERMINATION BY EXECUTIVE AND TERMINATION FOR CAUSE: 
BENEFITS.  Executive may terminate his employment with the Company by giving 
written notice 

EMPLOYMENT AGREEMENT - Page 8
<PAGE>

of his intent and stating an effective Termination Date at least ninety (90) 
days after the date of such notice; provided, however, that the Company may 
accelerate such effective date by paying Executive through the proposed 
Termination Date.  The Company may terminate Executive's employment with 
Cause at any time.  Upon such a termination by Executive or upon termination 
for Cause by the Company, this Agreement shall terminate and the Company 
shall pay to Executive all accrued compensation, unreimbursed expenses and 
the Other Benefits through the Termination Date.  Such amounts shall be paid 
to Executive in a lump sum in cash within thirty (30) days after the later of 
the date of termination or the date of the Board's decision as set forth 
herein. Upon a voluntary termination by employee or termination for Cause, 
Executive shall be entitled to receive no further salary nor consulting 
payments as set forth herein.  Upon such termination, all unvested options 
shall terminate and be of no further force or effect.

          (f)  DIRECTOR POSITIONS.  Executive agrees that upon termination of 
employment, for any reason, at the request of the Chairman of the Board, and 
if Executive owns less than 2,000,000 shares of HCC Common Stock or if 
Executive has been terminated for Cause, he will immediately tender his 
resignation from any and all Board positions held with the Company and/or any 
of its subsidiaries and affiliates, including without limitation, as Vice 
Chairman of the Company, Chairman of LDG, and a Director of Benefits.  If 
Executive remains as a Director, after such termination, Executive shall be 
compensated as an outside director.  While an outside Director, Executive 
shall be entitled to First Class Business Travel but shall no longer be 
entitled to use of corporate aircraft.

          (g)  SEVERANCE PAYMENT.  In addition to all other payments due 
hereunder in the event of Executive's termination other than for Cause, as 
both Chief Executive Officer and Chairman of the Board of LDG, Executive 
shall receive a severance payment in the amount of $1.3 million reduced by 
the corporate aircraft expense previously utilized by Executive since January 
1, 1998 in excess of $300,000 in each calendar year beginning January 1, 
1998.  At the Company's sole election, such severance may be paid in cash or 
by permitting the Executive to incur additional corporate aircraft expense.  

     6.   NON-COMPETITION, NON-SOLICITATION, AND CONFIDENTIALITY.  Executive 
recognizes and agrees that the benefit of not being employed at-will, is 
provided in consideration for, among other things, the agreements contained 
in this Section, as well as the Stock Options granted to Executive pursuant 
to this Agreement.  The Company agrees that while employed pursuant to this 
Agreement, Executive will be provided with confidential information of 
Company; specialized training on how to perform his duties; and contact with 
the Company's customers and potential customers.  Furthermore, in the event 
Executive is terminated without Cause, or terminates for Good Reason, and 
more than one (1) year remains on the existing Basic Term, then Executive 
shall receive additional consideration in an amount equal to the quotient of 
the Base Salary divided by 12, which shall thereupon be multiplied by the 
number of months remaining in the Basic Term minus 12 months and which shall 
be paid in one lump sum within ten (10) days of such termination.

     In consideration of all of the foregoing, Executive agrees as follows:

EMPLOYMENT AGREEMENT - Page 9
<PAGE>

          (a)  NON-COMPETITION DURING EMPLOYMENT.  Executive agrees during 
the Basic Term he will not compete with the Company by engaging in the 
conception, design, development, production, marketing, or servicing of any 
product or service that is substantially similar to the products or services 
which the Company provides, and that he will not work for, in any capacity, 
assist, or become affiliated with as an owner, partner, etc., either directly 
or indirectly, any individual or business which offers or performs services, 
or offers or provides products substantially similar to the services and 
products provided by Company.

          (b)  CONFLICTS OF INTEREST.  Executive agrees that during the Basic 
Term, he will not engage, either directly or indirectly, in any activity (a 
"Conflict of Interest") which might adversely affect the Company or its 
affiliates, including ownership of a material interest in any supplier, 
contractor, distributor, subcontractor, customer or other entity with which 
the Company does business or accepting any material payment, service, loan, 
gift, trip, entertainment, or other favor from a supplier, contractor, 
distributor, subcontractor, customer or other entity with which the Company 
does business, and that Executive will promptly inform the Chairman of the 
Company as to each offer received by Executive to engage in any such 
activity.  Executive further agrees to disclose to the Company any other 
facts of which Executive becomes aware which might in Executive's good faith 
judgment reasonably be expected to involve or give rise to a Conflict of 
Interest or potential Conflict of Interest.

          (c)  NON-COMPETITION AFTER TERMINATION.  Executive agrees that 
Executive shall not, at any time during the period of three (3) years (the 
"Non-Competition Period"; unless there shall be a Change of Control of HCC, 
in which case the Non-Competition Period shall be reduced to 18 months) after 
the termination of the Basic Term, for any reason, within any of the markets 
in which the Company has sold products or services or formulated a plan to 
sell products or services into a market during the last twelve (12) months of 
Executive's employ or which the Company enters into within three (3) months 
thereafter, engage in or contribute Executive's knowledge to any work which 
is competitive with or similar to a product, process, apparatus, service, or 
development on which Executive worked or with respect to which Executive had 
access to Confidential Information while employed by the Company; provided, 
however, this subsection (c) shall not operate to prevent Executive from 
engaging in retail insurance or re-insurance activities during such 
three-year period to the extent such activities do not compete or permit any 
other person or entity to compete with any business the Company or any of its 
subsidiaries or affiliated companies were engaged in at the time of such 
termination or which the Company enters into within three (3) months 
thereafter.  Following the expiration of said three (3) year period, 
Executive shall continue to be obligated under the Confidential Information 
Section of this Agreement not to use or to disclose Confidential Information 
of the Company so long as it shall not be publicly available.  It is 
understood that the geographical area set forth in this covenant is divisible 
so that if this clause is invalid or unenforceable in an included geographic 
area, that area is severable and the clause remains in effect for the 
remaining included geographic areas in which the clause is valid.

          (d)  NON-SOLICITATION OF CUSTOMERS.  Executive further agrees that 
for a period of three (3) years after the termination of the Basic Term 
(unless there shall be a Change 

EMPLOYMENT AGREEMENT - Page 10
<PAGE>

of Control of HCC in which case such period shall be reduced to 18 months), 
he will not solicit or accept any business from any customer or client or 
prospective customer or client with whom Executive dealt or solicited while 
employed by Company during the last twelve (12) months of his employment.

          (e)  NON-SOLICITATION OF EMPLOYEES.  Executive agrees that for the 
duration of the Basic Term, and for a period of three (3) years after the 
termination of the Basic Term, he will not either directly or indirectly, on 
his own behalf or on behalf of others, solicit, attempt to hire, or hire any 
person employed by Company to work for Executive or for another entity, firm, 
corporation, or individual.

          (f)  CONFIDENTIAL INFORMATION.  Executive further agrees that he 
will not, except as the Company may otherwise consent or direct in writing, 
reveal or disclose, sell, use, lecture upon, publish or otherwise disclose to 
any third party any Confidential Information or proprietary information of 
the Company, or authorize anyone else to do these things at any time either 
during or subsequent to his employment with the Company.  This Section shall 
continue in full force and effect after termination of Executive's employment 
and after the termination of this Agreement.  Executive's obligations under 
this Section with respect to any specific Confidential Information and 
proprietary information shall cease when that specific portion of the 
Confidential Information and proprietary information becomes publicly known, 
in its entirety and without combining portions of such information obtained 
separately.  It is understood that such Confidential Information and 
proprietary information of the Company include matters that Executive 
conceives or develops, as well as matters Executive learns from other 
employees of Company.  Confidential Information is defined to include 
information:  (1) disclosed to or known by the Executive as a consequence of 
or through his employment with the Company; (2) not generally known outside 
the Company; and (3) which relates to any aspect of the Company or its 
business, finances, operation plans, budgets, research, or strategic 
development.  Confidential Information includes, but is not limited to the 
Company's trade secrets, proprietary information, financial documents, long 
range plans, customer lists, employer compensation, marketing strategy, data 
bases, costing data, computer software developed by the Company, investments 
made by the Company, and any information provided to the Company by a third 
party under restrictions against disclosure or use by the Company or others.

          (g)  RETURN OF DOCUMENTS, EQUIPMENT, ETC.  All writings, records, 
and other documents and things comprising, containing, describing, 
discussing, explaining, or evidencing any Confidential Information, and all 
equipment, components, parts, tools, and the like in Executive's custody or 
possession that have been obtained or prepared in the course of Executive's 
employment with the Company shall be the exclusive property of the Company, 
shall not be copied and/or removed from the premises of the Company, except 
in pursuit of the business of the Company, and shall be delivered to the 
Company, without Executive retaining any copies, upon notification of the 
termination of Executive's employment or at any other time requested by the 
Company.  The Company shall have the right to retain, access, and inspect all 
property of Executive of any kind in the office, work area, and on the 
premises of the Company upon termination of Executive's employment and at any 
time during employment by the 

EMPLOYMENT AGREEMENT - Page 11
<PAGE>

Company to ensure compliance with the terms of this Agreement.

          (h)  REAFFIRM OBLIGATIONS.  Upon termination of his employment with 
the Company, Executive, if requested by Company, shall reaffirm in writing 
Executive's recognition of the importance of maintaining the confidentiality 
of the Company's Confidential Information and proprietary information, and 
reaffirm any other obligations set forth in this Agreement.

          (i)  PRIOR DISCLOSURE.  Executive represents and warrants that he 
has not used or disclosed any Confidential Information he may have obtained 
from the Company prior to signing this Agreement, in any way inconsistent 
with the provisions of this Agreement.

          (j)  CONFIDENTIAL INFORMATION OF PRIOR COMPANIES.  Executive will 
not disclose or use during the period of his employment with the Company any 
proprietary or Confidential Information or copyright works which Executive 
may have acquired because of employment with an employer other than the 
Company or acquired from any other third party, whether such information is 
in Executive's memory or embodied in a writing or other physical form.

          (k)  BREACH.  Executive agrees that any breach of Sections 5(a), 
(b), (c), (d), (e) or (f) above cannot be remedied solely by money damages, 
and that in addition to any other remedies Company may have, Company is 
entitled to obtain injunctive relief against Executive.  Nothing herein, 
however, shall be construed as limiting the Company's right to pursue any 
other available remedy at law or in equity, including recovery of damages and 
termination of this Agreement and/or any payments that may be due pursuant to 
this Agreement.

          (l)  RIGHT TO ENTER AGREEMENT.  Executive represents and covenants 
to Company that he has full power and authority to enter into this Agreement 
and that the execution of this Agreement will not breach or constitute a 
default of any other agreement or contract to which he is a party or by which 
he is bound.

          (m)  EXTENSION OF POST-EMPLOYMENT RESTRICTIONS.  In the event 
Executive breaches Sections 5(b), (c), (d), or (e) or (f) above, the 
restrictive time periods contained in those provisions will be extended by 
the period of time Executive was in violation of such provisions.

          (n)  ENFORCEABILITY.  The agreements contained in this Section 5 
are independent of the other agreements contained herein.  Accordingly, 
failure of the Company to comply with any of its obligations outside of this 
Section do not excuse Executive from complying with the agreements contained 
herein.

          (o)  SURVIVABILITY.  The agreements contained in Sections 5(c) 
through (g) shall survive the termination of this Agreement for any reason.

     7.   CONSULTING AGREEMENT.  (a)  Effective upon Executive's termination of
employment for any reason other than Executive's termination prior to the end of
the Basic Term 

EMPLOYMENT AGREEMENT - Page 12
<PAGE>

by the Company for Cause, HCC hereby retains Executive as a consultant (an 
independent contractor and not as an employee) for a period of five (5) years 
(the "Consulting Period").  Termination of the Basic Term shall not effect 
the Parties' rights and obligations under this Section 6.  Subject to the 
following, Executive agrees to provide, if requested, a minimum of 100 hours 
of service per year, or, as requested by the Company, up to a total of 500 
hours during any one year of the Consulting Period; provided, however, that 
the total number of hours to be worked over the duration of the Consulting 
Period shall not exceed 500 (the "Consulting Services").  The Consulting 
Services to be provided shall be commensurate with Executive's training, 
background, experience and prior duties with the Company.  Executive agrees 
to make himself reasonably available to provide such Consulting Services 
during the Consulting Period; provided, however, the Company agrees that it 
shall provide reasonable advance notice to Executive of its expected 
consulting needs and any request for Consulting Services hereunder shall not 
unreasonably interfere with Executive's other business activities and 
personal affairs as determined in good faith by Executive.  In addition, 
Executive shall not be required to perform any requested Consulting Services 
which, in Executive's good faith opinion, would cause Executive to breach any 
fiduciary duty or contractual obligation Executive may have to another 
employer.  Further, during the Consulting Period, Executive shall not be 
subject to any non-competition provisions except for the three-year period 
provided for in Section 5(c).  Unless waived by Executive, Executive shall 
not be required to perform Consulting Services for more than four (4) days 
during any week or for more than eight (8) hours during any day.  Executive's 
travel time shall constitute hours of Consulting Services for purposes of 
this Section 6.  The Parties contemplate that, when appropriate, the 
Consulting Services shall be performed at Executive's office, residence or at 
LDG's executive offices in Wakefield, Massachusetts, and may be performed  at 
such other locations only as they may mutually agree upon.  Executive shall 
be properly reimbursed for all travel and other expenses reasonably incurred 
by Executive in rendering the Consulting Services but Executive shall not be 
entitled to utilize corporate aircraft during the Consulting Period.  HCC 
shall pay Executive $100,000 per year (the "Yearly Consulting Fee") and a 
total of $500,000 (the "Total Consulting Fee") during the Consulting Period, 
payable monthly in arrears, provided, however, if Executive works in excess 
of 100 hours in any calendar year, such calendar year's Yearly Consulting Fee 
shall be increased by multiplying the number of hours in excess of 100 by 
$1,000 and such excess amount shall be reduced from the final Yearly 
Consulting Fee paid to Executive as set forth in this Section 6 and shall not 
increase the Total Consulting Fee.  Executive may elect to delay payment for 
services but not the services themselves.  Except as set forth below and in 
Sections 4(c) or 4(d) hereof, if Executive fails to provide the hours 
requested by the Company in any 12-month period, Executive's rights to 
receive any further Consulting Fee shall immediately terminate.  During the 
Consulting Period, Executive shall receive no employment benefits from HCC.  
If Executive dies or becomes Disabled during the Consulting Period neither he 
nor, on his death, his beneficiary or estate, shall receive or continue to 
receive as the case may be the Consulting Fee during the remainder of the 
Consulting Period.

          (b)  If Executive has elected to begin the Early Consulting Period,
during such Early Consulting Period Executive shall be required to provide
Consulting Services in any amount of, at least, 500 hours per each calendar
year.  During such Early Consulting Period, 

EMPLOYMENT AGREEMENT - Page 13
<PAGE>

Executive shall: (a) receive the Consulting Fee of $100,000 per year; (b) 
receive stock options in an amount equal to 25,000 shares per year 
(exercisable at a price as set forth in Section 3(c)(2) hereof); and (c) 
shall be entitled to the use of corporate aircraft in a manner determined in 
accordance with Section 3(g) hereof.  During such Early Consulting Period, 
Executive shall receive no employment benefits from HCC.  If Executive dies 
or becomes Disabled during the Early Consulting Period, for the remainder of 
such Early Consulting Period (but not for the Consulting Period) Executive 
(or, on his death, his beneficiary or estate) shall continue to receive as 
the case may be the Consulting Fee for the remainder of the Early Consulting 
Period. 

     8.   ASSIGNMENT.  This Agreement may be assigned by Company, but cannot 
be assigned by Executive.

     9.   BINDING AGREEMENT.  Executive understands that his obligations

to enforce any term or condition of this Agreement, or of any breach hereof, 
shall be deemed a waiver of such right in the future or of any other right or 
remedy available under this Agreement.

     11.  SEVERABILITY.  If any provision of this Agreement is determined to 
be void, invalid, unenforceable, or against public policy, such provisions 
shall be deemed severable from the Agreement, and the remaining provisions of 
the Agreement will remain unaffected and in full force and effect.

     12.  ARBITRATION.  In the event any dispute arises out of Executive's 
employment with the Company, or separation therefrom, which cannot be 
resolved by the Parties, such dispute 

EMPLOYMENT AGREEMENT - Page 14
<PAGE>

shall be submitted to final and binding arbitration.  The arbitration shall 
be conducted in accordance with the National Rules for the Resolution of 
Employment Disputes of the American Arbitration Association ("AAA").  If the 
Parties cannot agree on an arbitrator, a list of seven (7) arbitrators will 
be requested from AAA, and the arbitrator will be selected using alternate 
strikes with Executive striking first.  The cost of the arbitration will be 
shared equally by Executive and the Company.  Arbitration of such disputes is 
mandatory and in lieu of any and all civil causes of action and lawsuits 
either Party may have against the other arising out of Executive's employment 
with Company, or separation therefrom.  Such arbitration shall be held in 
Houston, Texas.

     13.  ENTIRE AGREEMENT.  The terms and provisions contained herein shall 
constitute the entire agreement between the Parties with respect to 
Executive's employment with Company during the time period covered by this 
Agreement.  This Agreement replaces and supersedes any and all existing

                              EMPLOYMENT AGREEMENT

     This Employment Agreement ("Agreement") is entered into effective as of 
the 1st day of January, 1998 (the "Effective Date"), between HCC INSURANCE 
HOLDINGS, INC. ("HCC" or "Company"), and FRANK J. BRAMANTI ("Executive"), 
sometimes collectively referred to herein as the "Parties."


                                R E C I T A L S:

     WHEREAS, Executive is to be employed as Executive Vice President of HCC, 
and as an integral part of its management who participates in the 
decision-making process relative to short and long-term planning and policy 
for the Company, will serve on the Company's Executive Committee;

     WHEREAS, it is the desire to the Board of Directors of HCC (the "Board") 
to (i) directly engage Executive as an officer of HCC and its subsidiaries; 
and (ii) directly engage, if elected, the services of Executive as a director 
of HCC and its subsidiaries; and

     WHEREAS, Executive is desirous of committing himself to serve HCC on the 
terms herein provided.

     NOW, THEREFORE, in consideration of the foregoing and of the respective 
covenants and agreements set forth below, the Parties agree as follows:

     1.   TERM.  The Company hereby agrees to employ Executive as an 
Executive Vice President, and Executive hereby agrees to accept such 
employment, on the terms and conditions set forth herein, for the period 
commencing on the Effective Date and expiring as of 11:59 p.m. on December 
31, 2002 (the "Basic Term") (unless sooner terminated as hereinafter set 
forth).

     2.   DUTIES.

          (a)  DUTIES AS EMPLOYEE OF THE COMPANY.  Executive shall, subject 
to the supervision of the Chief Executive Officer, the President, and the 
Board, have general management responsibilities in the ordinary course of 
HCC's business with all such powers with respect to such management as may be 
reasonably incident to such responsibilities.  During normal business hours, 
Executive shall devote his full time and attention to diligently attending to 
the business of the Company during the Basic Term.  During the Basic Term, 
Executive shall not directly or indirectly render any services of a business, 
commercial, or professional nature to any other person, firm, corporation, or 
organization, whether for compensation or otherwise, without the prior 
written consent of the Chairman of the Board.  However, Executive shall have 
the right to engage in such activities as may be appropriate in order to 
manage his personal investments so long as such activities do not interfere 
or conflict with the performance of his duties to the Company hereunder.  The 
conduct of such activity shall not be deemed to materially interfere or 
conflict with Executive's performance of his duties until Executive has been 
notified 

EMPLOYMENT AGREEMENT - Page 1
<PAGE>

in writing thereof and given a reasonable period in which to cure the same.

          (b)  OTHER DUTIES.  At all times during the Basic Term, the Company 
shall use its best efforts to cause Executive to be elected a director and to 
serve on the Executive Committee and Senior Management Committee of HCC.  Any 
such failure to use its best efforts prior to a Change of Control shall be a 
material breach of this Agreement for purposes of Paragraph (4)(a)(iv).  If 
elected, Executive agrees to serve as a director and on the Executive 
Committee and Senior Management Committee of HCC and of any of its 
subsidiaries and in one or more executive offices of any of HCC's 
subsidiaries, provided Executive is indemnified for serving in any and all 
such capacities in a manner acceptable to the Company and Executive.  If 
elected, Executive agrees that he shall not be entitled to receive any 
compensation for serving as a director of HCC or in any capacities of HCC's 
subsidiaries other than the compensation to be paid to Executive by the 
Company pursuant to this Agreement.

     3.   COMPENSATION AND RELATED MATTERS.  

          (a)  BASE SALARY.  Executive shall receive a base salary (the "Base 
Salary") paid by the Company at the annual rate of $325,000, during the 
period beginning on the Effective Date hereof and ending December 31, 2002, 
payable not less frequently than in substantially equal monthly installments. 
In such event, Executive will be entitled to paid vacation as set forth in 
Subparagraph 3(f)(i).  At any time on or after January 1, 2000, Executive 
may, at his option, remain as a full-time employee with increased vacation, 
in which case his Base Salary shall be reduced to $275,000 annually (the 
"Reduced Salary).  In such event, Executive will be entitled to paid vacation 
as set forth in Subparagraph 3(f)(ii) and shall be entitled to continued 
benefits from the Company.  Alternatively, at Executive's sole discretion and 
election, on or before January 1, 2000, Executive may voluntarily terminate 
his employment with the Company and elect to become a consultant to the 
Company for the remainder of the Basic Term (the "Consulting Period") at an 
annual consulting fee of $150,000.  In such event, Executive shall be 
required to perform 300 hours of service per annum on behalf of the Company 
as directed by the President or Chairman of the Board (the "Consulting 
Services").  The Consulting Services to be provided shall be commensurate 
with Executive's training, background, experience and prior duties with the 
Company.  Executive agrees to make himself reasonably available to provide 
such Consulting Services during the Consulting Period; provided, however, the 
Company agrees that it shall provide reasonable advance notice to Executive 
of its expected consulting needs and any request for Consulting Services 
hereunder shall not unreasonably interfere with Executive's other business 
activities and personal affairs, as determined in good faith by Executive.  
In addition, Executive shall not be required to perform any requested 
Consulting Services which, in Executive's good faith opinion, would cause 
Executive to breach any fiduciary duty or contractual obligation Executive 
may have to another employer.  Further, during the Consulting Period, 
Executive shall not be subject to any non-competition provisions except for 
the two-year period provided for in Paragraph 5(c).  Executive's travel time 
shall constitute hours of Consulting Services for purposes of this Paragraph 
3(a).  The Parties contemplate that, when appropriate, the Consulting 
Services shall be performed at Executive's office, residence or at the 
Company's executive offices in Houston, Texas and may be performed at such 
other locations only as they may mutually agree upon.  Executive shall be 
promptly reimbursed for all travel and other expenses reasonably incurred by 
Executive in rendering the Consulting Services.  

EMPLOYMENT AGREEMENT - Page 2
<PAGE>

Executive's annual consulting fee shall be paid quarterly in advance. In such 
event, Executive, acting as a consultant, shall be entitled to no further 
benefits from the Company.

          (b)  BONUS PAYMENTS.  Executive shall be entitled to receive, in 
addition to the Base Salary, an annual cash bonus payment in an amount, which 
may be zero, to be determined at the sole discretion of the Compensation 
Committee.  If Executive elects to become a Consultant, he shall receive no 
bonus.

          (c)  STOCK OPTIONS.  In addition to stock options previously 
granted to Executive, in partial consideration for Executive's 
non-competition agreements, set forth herein, Executive shall be provided 
with additional options to purchase HCC shares as follows:

          (1)  100,000 shares to be granted effective as of January 7,
               1998, at an exercise price of $16.50 per share vesting in
               two equal installments of 50,000 each on December 31, 1998
               and December 31, 1999; and

          (2)  25,000 shares on December 31, of each year this Agreement is
               in effect and Executive is a full time employee on such
               date.  Such options shall be priced at the average closing
               price of HCC shares for the month of December of the year of
               the grant.  Any options so granted shall vest immediately. 
               Executive shall receive no options if he is acting as a
               consultant.

          (d)  EXPENSES.  During the Basic Term, Executive shall be entitled 
to receive reimbursement for all reasonable expenses incurred by him in 
accordance with the policies and procedures established by the Board for the 
Company's senior executive officers in performing services hereunder, 
provided that Executive properly accounts therefor in accordance with Company 
policy.

          (e)  OTHER BENEFITS.  Except if Executive elects to become a 
consultant, as set forth above, Executive shall be entitled to participate in 
or receive benefits under any compensatory employee benefit plan or other 
arrangement made available by the Company now or in the future to its senior 
executive officers and key management employees, subject to and on a basis 
consistent with the terms, conditions, and overall administration of such 
plan or arrangement.  Nothing paid to Executive under any plan or arrangement 
presently in effect or made available in the future shall be deemed to be in 
lieu of the Base Salary payable to Executive pursuant to Paragraph (a) of 
this Section.  The Company shall not make any changes in any employee benefit 
plans or other arrangements in effect on the date hereof or subsequently in 
effect in which Executive currently or in the future participates (including, 
without limitation, each pension and retirement plan, supplemental pension 
and retirement plan, savings and profit sharing plan, stock or unit ownership 
plan, stock or unit purchase plan, stock or unit option plan, life insurance 
plan, medical insurance plan, disability plan, dental plan, health and 
accident plan, or any other similar plan or arrangement) that would adversely 
affect Executive's rights or benefits thereunder, unless such change occurs 
pursuant to a program applicable to substantially all executives of the 
Company and does not result in a proportionately greater reduction in the 
rights of or benefits to Executive as compared with any other executive of 
the Company.

<PAGE>

          (f)  VACATIONS.  (i) Executive shall be entitled to thirty (30) 
paid vacation days per year during the Basic Term, provided however, (ii) if 
Executive should elect to remain a full-time employee and not a consultant 
after January 1, 2000 at the Reduced Salary, Executive shall be entitled to 
sixty (60) paid vacation days per year from such date.  There shall be no 
carryover of unused vacation from year to year.  For purposes of this 
Paragraph, weekends shall not count as vacation days, and Executive shall 
also be entitled to all paid holidays and personal days given by the Company 
to its senior executive officers.

          (g)  PERQUISITES.  Executive shall be entitled to receive the 
perquisites and fringe benefits appertaining to an executive officer of HCC 
in accordance with any practice established by the Compensation Committee. 
Notwithstanding, and in addition to, any perquisites to which Executive is 
entitled pursuant to the preceding sentence, Executive shall, whether acting 
as an employee or as a consultant:  (i) have use of a 1998 Mercedes 500 SEL 
automobile, and the Company shall pay all expenses related to Executive's use 
of such car, including gasoline, insurance, and maintenance; (ii) be allowed 
to travel on business utilizing first class passage (whether domestic or 
international); (iii) be reimbursed for annual club dues for Lakeside Country 
Club; and (iv) receive a total of $1,000,000 term life insurance (which shall 
be in addition to the standard benefits provided to Executive under the 
Company's group life insurance program that covers officers).

          (h)  PRORATION.  Any payments or benefits payable to Executive 
hereunder in respect of any calendar year during which Executive is employed 
by the Company for less than the entire year, unless otherwise provided in 
the applicable plan or arrangement, shall be prorated in accordance with the 
number of days in such calendar year during which he is so employed.  
Notwithstanding the foregoing, any payments pursuant to Paragraphs 4(b)(4), 
4(c) or 4(d) of this Agreement shall not be subject to proration.  

     4.   TERMINATION.

          (a)  DEFINITIONS.

               (1)  "CAUSE" shall mean:

                    (i)   Material dishonesty which is not the result of an
     inadvertent or innocent mistake of Executive with respect to the Company or
     any of its subsidiaries;

                    (ii)  Willful misfeasance or nonfeasance of duty by
     Executive intended to injure or having the effect of injuring in some
     material fashion the reputation, business, or business relationships of the
     Company or any of its subsidiaries or any of their respective officers,
     directors, or employees;

                    (iii) Material violation by Executive of any material term
     of this Agreement; or

                    (iv)  Conviction of Executive of any felony, any crime
     involving 

EMPLOYMENT AGREEMENT - Page 4
<PAGE>

     moral turpitude or any crime other than a vehicular offense which could 
     reflect in some material fashion unfavorably upon the Company or any of 
     its subsidiaries.

Executive may not be terminated for Cause unless and until there has been 
delivered to Executive written notice from the Board supplying the 
particulars of Executive's acts or omissions that the Board believes 
constitute Cause, a reasonable period of time (not less than 30 days) has 
been given to Executive after such notice to either cure the same or to meet 
with the Board, with his attorney if so desired by Executive, and following 
which the Board by action of not less than two-thirds of its members 
furnishes to Executive a written resolution specifying in detail its findings 
that Executive has been terminated for Cause as of the date set forth in the 
notice to Executive.

               (2)  A "CHANGE OF CONTROL" shall be deemed to have occurred if:

                    (i)   Any "person" or "group" (within the meaning of
     Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934) other
     than a trustee or other fiduciary holding securities under an employee
     benefit plan of the Company becomes the "beneficial owner" (as defined in
     Rule 13d-3 under the Securities Exchange Act of 1934), directly or
     indirectly, of 50% or more of the Company's then outstanding voting common
     stock; or

                    (ii)  At any time during the period of three (3) consecutive
     years (not including any period prior to the date hereof), individuals who
     at the beginning of such period constituted the Board (and any new director
     whose election by the Board or whose nomination for election by the
     Company's shareholders were approved by a vote of at least two-thirds of
     the directors then still in office who either were directors at the
     beginning of such period or whose election or nomination for election was
     previously so approved) cease for any reason to constitute a majority
     thereof; or

                    (iii) The shareholders of the Company approve a merger or
     consolidation of the Company with any other corporation, other than a
     merger or consolidation (a) in which a majority of the directors of the
     surviving entity were directors of the Company prior to such consolidation
     or merger, and (b) which would result in the voting securities of the
     Company outstanding immediately prior thereto continuing to represent
     (either by remaining outstanding or by being changed into voting securities
     of the surviving entity) more than 50% of the combined voting power of the
     voting securities of the surviving entity outstanding immediately after
     such merger or consolidation; or

                    (iv)  The shareholders approve a plan of complete
     liquidation of the Company or an agreement for the sale or disposition by
     the Company of all or substantially all of the Company's assets.

               (3)  A "DISABILITY" shall mean the absence of Executive from 
Executive's duties with the Company on a full-time basis for 180 consecutive 
days, or 180 days in a 365-day period, as a result of incapacity due to 
mental or physical illness which results in the 

EMPLOYMENT AGREEMENT - Page 5
<PAGE>

Executive being unable to perform the essential functions of his position, 
with or without reasonable accommodation.

               (4)  A "GOOD REASON" shall mean any of the following (without 
Executive's express written consent):

                    (i)   Following a Change of Control, a material alteration
     in the nature or status of Executive's title, duties or responsibilities,
     or the assignment of duties or responsibilities inconsistent with
     Executive's status, title, duties and responsibilities;

                    (ii)  A failure by the Company to continue in effect any
     employee benefit plan in which Executive was participating, or the taking
     of any action by the Company that would adversely affect Executive's
     participation in, or materially reduce Executive's benefits under, any such
     employee benefit plan, unless such failure or such taking of any action
     adversely affects the senior members of corporate management of the Company
     generally to the same extent;

                    (iii) A relocation of the Company's principal executive
     offices, or Executive's relocation to any place other than the principal
     executive offices, exceeding a distance of fifty (50) miles from the
     Company's current executive office located in Houston, Texas, except for
     reasonably required travel by Executive on the Company's business;

                    (iv)  Any material breach by the Company of any provision of
     this Agreement; or

                    (v)   Any failure by the Company to obtain the assumption
     and performance of this Agreement by any successor (by merger,
     consolidation, or otherwise) or assign of the Company.

However, Good Reason shall exist with respect to an above specified matter only
if such matter is not corrected by the Company within thirty (30) days of its
receipt of written notice of such matter from Executive, and in no event shall a
termination by Executive occurring more than ninety (90) days following the date
of the event described above be a termination for Good Reason due to such event.

               (5)  "TERMINATION DATE" shall mean the date Executive is 
terminated for any reason pursuant to this Agreement.

          (b)  TERMINATION WITHOUT CAUSE, OR TERMINATION FOR GOOD REASON: 
BENEFITS.  In the event there is a termination by the Company without Cause, 
or if Executive terminates for Good Reason (a "Termination Event"), this 
Agreement shall terminate and Executive shall be entitled to the following 
severance benefits:

               (1)  For a  period of twelve (12) months after the Termination
     Date (unless the remainder of the Basic Term is less than twelve
     (12) months, in which case, 

EMPLOYMENT AGREEMENT - Page 6
<PAGE>

     for an amount of time equal to the remainder of the Basic Term), Base 
     Salary (as defined in Paragraph 3(a)), at the rate and payable quarterly 
     unless such termination is by the Company without Cause, in which event 
     such amount of Base Salary shall be paid in a lump sum within ten 
     (10) days of the Termination Event.

               (2)  If there is a Change of Control or termination by the
     Company without Cause or by Executive for Good Reason any  stock options
     and other stock-related grants ("Stock Awards") which Executive has
     received under any of the HCC stock plans shall vest immediately; provided,
     however, that the options provided for in Paragraph 3(c)(2) shall be
     granted as of the Termination Date and shall be priced at the closing price
     of HCC shares as of such date.  If there is a termination for Good Reason
     or by the Company other than for Cause, all options shall be exercisable
     for one year or the remainder of their term, whichever is less.   

               (3)  To the extent not theretofore paid or provided, the Company
     shall timely pay or provide to Executive any other amounts or benefits
     required to be paid or provided or which Executive is eligible to receive
     under any plan, program, policy or practice, or contract or agreement of
     the Company and its affiliated companies for the period of time equal to
     the remainder of the Basic Term (such other amounts and benefits shall be
     hereinafter referred to as the "Other Benefits").  Without limiting the
     preceding sentence, through December 31, 2002 the Company, at its sole
     expense, shall continue to provide (through its own plan and/or individual
     policies) Executive (and Executive's dependents) with health benefits no
     less favorable than the group health plan benefits provided during such
     period to any senior executive officer of the Company or any affiliated
     company (to the extent any such coverage or benefits are taxable to
     Executive by reason of being provided under a self-insured health plan of
     the Company or an affiliate, the Company shall make Executive "whole" for
     the same on an after-tax basis).  In any event, the Other Benefits provided
     for pursuant to this Paragraph shall be secondary to any benefits and
     coverage Executive (or his dependents) receive from another employer.

               (4)  If any such Termination occurs on or after October 1 of any
     year, such cash and/or stock bonus that Executive otherwise would have
     received if such Termination had not taken place.

               (5)  If Executive receives any payments whether or not pursuant
     to this Agreement which are subject to an excise tax imposed under
     Section 4999 of the Internal Revenue Code of 1986, as amended, or any
     similar tax imposed under federal, state, or local law (collectively,
     "Excise Taxes"), the Company shall pay to Executive (on or before the date
     on which the Company is required to withhold such Excise Taxes), 1) an
     additional amount equal to all Excise Taxes then due and payable, and
     2) the amount necessary to defray Executive's increased (federal, state,
     and local) tax liability arising due to payment of the amount specified in
     this Subsection (5) which shall include any costs and expenses, including
     penalties and interest incurred by Executive in connection with any audit,
     proceedings, etc. related to the payment of such Excise Taxes or this
     payment.  For purposes of calculating the amount payable to Executive under
     this 

EMPLOYMENT AGREEMENT - Page 7
<PAGE>

     Paragraph, the federal and state income tax rates used shall be the
     highest marginal federal and state rates applicable to ordinary income in
     Executive's state of residence, taking into account any federal income tax
     deductions or credits available to Executive for state income taxes.  The
     Company shall cause its independent auditors to calculate such amount and
     provide Executive a copy of such calculation at least ten (10) days prior
     to the date specified above for payment of such amount.  It is the intent
     of the Parties that this Subsection (5) shall place Executive in the same
     net after-tax position Executive would have been in had no payment been
     subject to an Excise Tax and, notwithstanding anything herein to the
     contrary, it shall be construed to effectuate said result.

               (6)  All accrued compensation and unreimbursed expenses through
     the Termination Date.  Such amounts shall be paid to Executive in a lump
     sum in cash within thirty (30) days after the Termination Date; and

               (7)  Executive shall be free to accept other employment during
     such period, and there shall be no offset of any employment compensation
     earned by Executive in such other employment during such period against
     payments due Executive under this Paragraph (4), and there shall be no
     offset in any compensation received from such other employment against the
     Base Salary set forth above.

          (c)  TERMINATION IN EVENT OF DEATH:  BENEFITS.  If Executive's 
employment is terminated by reason of Executive's death during the Basic 
Term, this Agreement shall terminate without further obligation to 
Executive's legal representatives under this Agreement, other than for 
payment of all accrued compensation, unreimbursed expenses, the timely 
payment or provision of Other Benefits through the date of death, and, if 
such death occurs on or after October 1 of any year, such cash or stock bonus 
as Executive would otherwise have been awarded in such year if Executive's 
death had not occurred.  Such amounts shall be paid to Executive's estate or 
beneficiary, as applicable, in a lump sum in cash within ninety (90) days 
after the date of death.  With respect to the provision of Other Benefits, 
the term Other Benefits as used in this Paragraph 4(c) shall include, without 
limitation, and Executive's estate and/or beneficiaries shall be entitled to 
receive, benefits at least equal to the most favorable benefits provided by 
the Company to the estates and beneficiaries of other executive level 
employees of the Company under such plans, programs, practices, and policies 
relating to death benefits, if any, as in effect with respect to other 
executives and their beneficiaries at any time during the 120-day period 
immediately preceding the date of death.  Additionally, all Stock Awards for 
which Executive would have been eligible had he completed the Basic Term 
(except as set forth in Paragraph 4(b)(2)), shall be accelerated, and 
Executive's estate or beneficiary shall be vested in such Stock Awards as of 
the date of Executive's termination.

          (d)  TERMINATION IN EVENT OF DISABILITY:  BENEFITS.  If Executive's 
employment is terminated by reason of Executive's Disability during the Basic 
Term, this Agreement shall continue in full force for a period of one (1) 
year following such Disability and if such Disability occurs on or after 
October 1 of any year Executive shall be entitled to the same cash or stock 
bonus in such year that Executive would have been awarded if such Disability 
had not occurred. Following such one (1) year period, this Agreement shall 
continue in full force except that (a) the Base Salary shall be reduced by 
50% and (b) Executive shall not be entitled to 

EMPLOYMENT AGREEMENT - Page 8
<PAGE>

any subsequent cash or stock bonuses.  In addition, all outstanding Stock 
Awards shall vest immediately upon such termination due to Disability.

          (e)  VOLUNTARY TERMINATION BY EMPLOYEE AND TERMINATION FOR CAUSE: 
BENEFITS.  Executive may terminate his employment with the Company without 
Good Reason by giving written notice of his intent and stating an effective 
Termination Date at least ninety (90) days after the date of such notice; 
provided, however, that the Company may accelerate such effective date by 
paying Executive through the proposed Termination Date and also vesting 
awards that would have vested but for this acceleration of the proposed 
Termination Date. Upon such a termination by Executive, except as provided in 
Paragraph 3(a), or upon termination for Cause by the Company, this Agreement 
shall terminate, and the Company shall pay to Executive all accrued 
compensation, unreimbursed expenses and the Other Benefits through the 
Termination Date.  Such amounts shall be paid to Executive in a lump sum in 
cash within thirty (30) days after the date of termination.

          (f)  DIRECTOR POSITIONS.  Executive agrees that upon termination of 
employment, for any reason, at the request of the Chairman of the Board, 
Executive will immediately tender his resignation from any and all Board 
positions held with the Company and/or any of its subsidiaries and 
affiliates. If Executive remains as a director, after such termination, 
Executive shall be compensated as an outside director.

     5.   NON-COMPETITION, NON-SOLICITATION, AND CONFIDENTIALITY.  Executive 
recognizes and agrees that the benefit of not being employed at-will, is 
provided in consideration for, among other things, the agreements contained 
in this Section as well as the Stock Options granted to Executive pursuant to 
this Agreement.  The Company agrees that while employed pursuant to this 
Agreement, Executive will be provided with confidential information of 
Company; specialized training on how to perform his duties; and contact with 
the Company's customers and potential customers.  Furthermore, in the event 
Executive is terminated without Cause, or terminates for Good Reason; and 
more than one (1) year remains on the existing Basic Term, then Executive 
shall receive additional consideration in an amount equal to the quotient of 
the Base Salary divided by 12, which shall thereupon be multiplied by the 
number of months remaining in the Basic Term minus 12 months, and which shall 
be paid in one lump sum within ten (10) days of such termination.

     In consideration of all of the foregoing, Executive agrees as follows:

          (a)  NON-COMPETITION DURING EMPLOYMENT.  Executive agrees during 
the Basic Term he will not compete with the Company by engaging in the 
conception, design, development, production, marketing, or servicing of any 
product or service that is substantially similar to the products or services 
which the Company provides, and that he will not work for, in any capacity, 
assist, or become affiliated with as an owner, partner, etc., either directly 
or indirectly, any individual or business which offers or performs services, 
or offers or provides products substantially similar to the services and 
products provided by Company, provided, Executive shall not be prevented from 
owning no more than 2% of any Company whose stock is publicly traded.

EMPLOYMENT AGREEMENT - Page 9
<PAGE>

          (b)  CONFLICTS OF INTEREST.  Executive agrees that during the Basic 
Term, he will not engage, either directly or indirectly, in any activity (a 
"Conflict of Interest") which might adversely affect the Company or its 
affiliates, including ownership of a material interest in any supplier, 
contractor, distributor, subcontractor, customer or other entity with which 
the Company does business or accepting any material payment, service, loan, 
gift, trip, entertainment, or other favor from a supplier, contractor, 
distributor, subcontractor, customer or other entity with which the Company 
does business, and that Executive will promptly inform the Chairman of the 
Company as to each offer received by Executive to engage in any such 
activity.  Executive further agrees to disclose to the Company any other 
facts of which Executive becomes aware which might in Executive's good faith 
judgment reasonably be expected to involve or give rise to a Conflict of 
Interest or potential Conflict of Interest.

          (c)  NON-COMPETITION AFTER TERMINATION.  Executive agrees that 
Executive shall not, at any time during the period of two (2) years after the 
termination of the Basic Term for any reason, within any of the markets in 
which the Company has sold products or services or formulated a plan to sell 
products or services into a market during the last twelve (12) months of 
Executive's employ or which the Company enters into within three (3) months 
thereafter, engage in or contribute Executive's knowledge to any work which 
is competitive with or similar to a product, process, apparatus, service, or 
development on which Executive worked or with respect to which Executive had 
access to Confidential Information while employed by the Company; provided, 
however, this Paragraph (c) shall not operate to prevent Executive from 
engaging in retail insurance or re-insurance activities during such two-year 
period to the extent such activities do not compete or permit any other 
person or entity to compete with any business the Company or any of its 
subsidiaries or affiliated companies were engaged in at the time of such 
termination or which the Company enters into within three (3) months 
thereafter.  Following the expiration of said two (2) year period, Executive 
shall continue to be obligated under the Confidential Information Paragraph 
of this Agreement not to use or to disclose Confidential Information of the 
Company so long as it shall not be publicly available.  It is understood that 
the geographical area set forth in this covenant is divisible so that if this 
clause is invalid or unenforceable in an included geographic area, that area 
is severable and the clause remains in effect for the remaining included 
geographic areas in which the clause is valid.

          (d)  NON-SOLICITATION OF CUSTOMERS.  Executive further agrees that 
for a period of two (2) years after the termination of the Basic Term, he 
will not solicit or accept any business from any customer or client or 
prospective customer or client with whom Executive dealt or solicited while 
employed by Company during the last twelve (12) months of his employment.

          (e)  NON-SOLICITATION OF EMPLOYEES.  Executive agrees that for the 
duration of the Basic Term, and for a period of two (2) years after the 
termination of the Basic Term, he will not either directly or indirectly, on 
his own behalf or on behalf of others, solicit, attempt to hire, or hire any 
person employed by Company to work for Executive or for another entity, firm, 
corporation, or individual.

          (f)  CONFIDENTIAL INFORMATION.  Executive further agrees that he 
will not, except as the Company may otherwise consent or direct in writing, 
reveal or disclose, sell, use, 

EMPLOYMENT AGREEMENT - Page 10
<PAGE>

lecture upon, publish or otherwise disclose to any third party any 
Confidential Information or proprietary information of the Company, or 
authorize anyone else to do these things at any time either during or 
subsequent to his employment with the Company.  This Section shall continue 
in full force and effect after termination of Executive's employment and 
after the termination of this Agreement.  Executive's obligations under this 
Paragraph with respect to any specific Confidential Information and 
proprietary information shall cease when that specific portion of the 
Confidential Information and proprietary information becomes publicly known, 
in its entirety and without combining portions of such information obtained 
separately.  It is understood that such Confidential Information and 
proprietary information of the Company include matters that Executive 
conceives or develops, as well as matters Executive learns from other 
employees of Company.  Confidential Information is defined to include 
information:  (1) disclosed to or known by the Executive as a consequence of 
or through his employment with the Company; (2) not generally known outside 
the Company; and (3) which relates to any aspect of the Company or its 
business, finances, operation plans, budgets, research, or strategic 
development.  "Confidential Information" includes, but is not limited to the 
Company's trade secrets, proprietary information, financial documents, long 
range plans, customer lists, employer compensation, marketing strategy, data 
bases, costing data, computer software developed by the Company, investments 
made by the Company, and any information provided to the Company by a third 
party under restrictions against disclosure or use by the Company or others.

          (g)  RETURN OF DOCUMENTS, EQUIPMENT, ETC.  All writings, records, 
and other documents and things comprising, containing, describing, 
discussing, explaining, or evidencing any Confidential Information, and all 
equipment, components, parts, tools, and the like in Executive's custody or 
possession that have been obtained or prepared in the course of Executive's 
employment with the Company shall be the exclusive property of the Company, 
shall not be copied and/or removed from the premises of the Company, except 
in pursuit of the business of the Company, and shall be delivered to the 
Company, without Executive retaining any copies, upon notification of the 
termination of Executive's employment or at any other time requested by the 
Company.  The Company shall have the right to retain, access, and inspect all 
property of Executive of any kind in the office, work area, and on the 
premises of the Company upon termination of Executive's employment and at any 
time during employment by the Company to ensure compliance with the terms of 
this Agreement.

          (h)  REAFFIRM OBLIGATIONS.  Upon termination of his employment with 
the Company, Executive, if requested by Company, shall reaffirm in writing 
Executive's recognition of the importance of maintaining the confidentiality 
of the Company's Confidential Information and proprietary information, and 
reaffirm any other obligations set forth in this Agreement.

          (i)  PRIOR DISCLOSURE.  Executive represents and warrants that he 
has not used or disclosed any Confidential Information he may have obtained 
from Company prior to signing this Agreement, in any way inconsistent with 
the provisions of this Agreement.

          (j)  CONFIDENTIAL INFORMATION OF PRIOR COMPANIES.  Executive will 
not disclose or use during the period of his employment with the Company any 
proprietary or Confidential Information or Copyright Works which Executive 
may have acquired because of employment with an employer other than the 
Company or acquired from any other third party, 

EMPLOYMENT AGREEMENT - Page 11
<PAGE>

whether such information is in Executive's memory or embodied in a writing or 
other physical form.

          (k)  BREACH.  Executive agrees that any breach of Paragraphs 5(a), 
(c), (d), (e) or (f) above cannot be remedied solely by money damages, and 
that in addition to any other remedies Company may have, Company is entitled 
to obtain injunctive relief against Executive.  Nothing herein, however, 
shall be construed as limiting Company's right to pursue any other available 
remedy at law or in equity, including recovery of damages and termination of 
this Agreement and/or any payments that may be due pursuant to this Agreement.

          (l)  RIGHT TO ENTER AGREEMENT.  Executive represents and covenants 
to Company that he has full power and authority to enter into this Agreement 
and that the execution of this Agreement will not breach or constitute a 
default of any other agreement or contract to which he is a party or by which 
he is bound.

          (m)  EXTENSION OF POST-EMPLOYMENT RESTRICTIONS.  In the event 
Executive breaches Paragraphs 5(b), (d), or (e) above, the restrictive time 
periods contained in those provisions will be extended by the period of time 
Executive was in violation of such provisions.

          (n)  ENFORCEABILITY.  The agreements contained in Section 5 are 
independent of the other agreements contained herein.  Accordingly, failure 
of the Company to comply with any of its obligations outside of this 
Paragraph do not excuse Executive from complying with the agreements 
contained herein.

          (o)  SURVIVABILITY.  The agreements contained in Paragraphs 
5(c)-(g) shall survive the termination of this Agreement for any reason.

     6.   ASSIGNMENT.  This Agreement cannot be assigned by Executive.  The 
Company may assign this Agreement only to a successor (whether direct or 
indirect, by purchase, merger, consolidation or otherwise) to all or 
substantially all of the business and assets of the Company provided such 
successor expressly agrees in writing reasonably satisfactory to Executive to 
assume and 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 and 
assignment had taken place.  Failure of the Company to obtain such written 
agreement prior to the effectiveness of any such succession shall be a 
material breach of this Agreement.

     7.   BINDING AGREEMENT.  Executive understands that his obligations 
under this Agreement are binding upon Executive's heirs, successors, personal 
representatives, and legal representatives.

     8.   NOTICES.  All notices pursuant to this Agreement shall be in 
writing and sent certified mail, return receipt requested, addressed as set 
forth below, or by delivering the same in person to such party, or by 
transmission by facsimile to the number set forth below (which shall not 
constitute notice). Notice deposited in the United States Mail, mailed in the 
manner described hereinabove, shall be effective upon deposit.  Notice given 
in any other manner shall be effective only if and when received:

employment with or by the Company, or separation/termination therefrom,

striking first.  The cost of the arbitration will be shared equally by 
Executive and Company; provided, however, the Company shall promptly 
reimburse Executive for all costs and expenses incurred in connection with 
any dispute in an amount up to, but not exceeding twenty percent (20%) of 
Executive's Base Salary (or, if the dispute arises during the Consulting 
Period, Executive's Base Salary as in effect immediately prior to the 
beginning of the Consulting Period) unless such termination was for Cause in 
which event Executive shall not be entitled to reimbursement unless and until 
it is determined he was terminated other than for Cause.  Arbitration of such 
disputes is mandatory and in lieu of any and all civil causes of action and 
lawsuits either party may have against the other arising out of Executive's 
employment with Company, or separation therefrom.  Such arbitration shall be 
held in Houston, Texas.

constitute

employment with Company during the time period covered by this Agreement.  
This Agreement replaces and supersedes any and all existing Agreements 
entered into between Executive and the Company relating generally to the same 
subject matter, if any, and shall be binding upon Executive's heirs, 
executors, administrators, or other legal representatives or assigns.

     13.  MODIFICATION OF AGREEMENT.  This Agreement may not be changed or 
modified or released or discharged or abandoned or otherwise terminated, in 
whole or in part, except by an instrument in writing signed by the Executive 
and an officer or other authorized executive of Company.

     14.  UNDERSTAND AGREEMENT.  Executive represents and warrants that he 
has read and understood each and every provision of this Agreement, and

counsel of choice, if necessary and desired, in order to interpret any and 
all provisions of this Agreement, and that Executive has freely and 
voluntarily entered into this Agreement.

     15.  GOVERNING LAW.  This Agreement shall be governed by and construed 
in accordance with the laws of the State of Texas.

     16.  JURISDICTION AND VENUE.  With respect to any litigation regarding

jurisdiction in the state and federal courts in Harris County, Texas.

                              EMPLOYMENT AGREEMENT

    This Employment Agreement ("Agreement") is entered into effective as of 
the 1st day of January, 1998 (the "Effective Date"), between HCC INSURANCE 
HOLDINGS, INC. ("HCC" or "Company"), and PETER B. SMITH, JR. ("Executive"), 
sometimes collectively referred to herein as the "Parties."


                                R E C I T A L S:

    WHEREAS, Executive is to be employed as Executive Vice President of HCC, 
and as an integral part of its management who participates in the 
decision-making process relative to short and long term planning and policy 
for the Company, will serve on the Company's Executive Committee;

    WHEREAS, it is the desire of the Board of Directors of HCC (the "Board") 
to (i) directly engage Executive as an officer of HCC and its subsidiaries; 
and (ii) directly engage, if elected, the services of Executive as a director 
of HCC and its subsidiaries; and

    WHEREAS, Executive is desirous of committing himself to serve HCC on the 
terms herein provided.

    NOW, THEREFORE, in consideration of the foregoing and of the respective 
covenants and agreements set forth below, the Parties agree as follows:

    1.    TERM.  The Company hereby agrees to employ Executive as an 
Executive Vice President, and Executive hereby agrees to accept such 
employment, on the terms and conditions set forth herein, for the period 
commencing on the Effective Date and expiring as of 11:59 p.m. on December 
31, 2002 (the "Basic Term") (unless sooner terminated as hereinafter set 
forth).

    2.    DUTIES.

          (a)    Duties as Employee of the Company.  Executive shall, subject 
to the supervision of the Chief Executive Officer, President, and Board, have 
general management responsibilities in the ordinary course of HCC's business 
with all such powers with respect to such management as may be reasonably 
incident to such responsibilities.  During normal business hours, Executive 
shall devote his full time and attention to diligently attending to the 
business of the Company during the Basic Term.  During the Basic Term, 
Executive shall not directly or indirectly render any services of a business, 
commercial, or professional nature to any other person, firm, corporation, or 
organization, whether for compensation or otherwise, without the prior 
written consent of the Chairman of the Board.  However, Executive shall have 
the right 

EMPLOYMENT AGREEMENT - Page 1
<PAGE>

to engage in such activities as may be appropriate in order to manage his 
personal investments so long as such activities do not materially interfere 
or conflict with the performance of his duties to the Company hereunder.  The 
conduct of such activity shall not be deemed to materially interfere or 
conflict with Executive's performance of his duties until Executive has been 
notified in writing thereof and given a reasonable period in which to cure 
the same.  

    (b)    OTHER DUTIES.  At all times during the Basic Term the Company 
shall use its best efforts to cause Executive to be elected a director and to 
serve on the Executive Committee and Senior Management Committee of HCC.  Any 
such failure to use its best efforts prior to a Change of Control shall be a 
material breach of this Agreement for purposes of Paragraph 4(a)(iv).  If 
elected, Executive agrees to serve as a director, member of the Executive 
Committee and member of the Senior Management Committee of HCC and of any of 
its subsidiaries and in one or more executive offices of any of HCC's 
subsidiaries, provided Executive is indemnified for serving in any and all 
such capacities in a manner acceptable to the Company and Executive.  
Executive will serve as President and Chief Executive Officer of Houston 
Casualty Company, U.S. Specialty Insurance Company and Trafalgar Insurance 
Company and as Chairman of Avemco Insurance Company.  If elected, Executive 
agrees that he shall not be entitled to receive any compensation for serving 
as a director of HCC or in any capacities of HCC's subsidiaries other than 
the compensation to be paid to Executive by the Company pursuant to this 
Agreement.

    3.    COMPENSATION AND RELATED MATTERS.  

          (a)    BASE SALARY.  Executive shall receive a base salary paid by 
the Company at the annual rate of $325,000, during the period beginning on 
the Effective Date payable not less frequently than in substantially equal 
monthly installments. Such Base Salary shall increase $25,000 each January 1, 
commencing January 1, 1999 until Executive's base salary reaches $425,000.  
For purposes of this Agreement, "Base Salary" shall mean the Executive's 
initial base salary and, when increased, the increased base salary.

          (b)    BONUS PAYMENTS.  Each year, Executive shall be entitled to 
receive, in addition to the Base Salary, an annual bonus payment based on 
HCC's annual operating earnings per share ("OEPS"), as set forth below:

          $37,500 bonus if OEPS growth is 10% or more in any one year period;

          $75,000 bonus if OEPS growth is 15% or more in any one year period; 
          and

          $150,000 bonus if OEPS growth is 20% or more in any one year period.

For purposes of this Agreement, OEPS is defined as HCC's consolidated net 
earnings less capital 

EMPLOYMENT AGREEMENT - Page 2
<PAGE>

gains/losses, currency gains/losses, and any nonrecurring merger and 
acquisition income or expenses as reported in HCC's Annual Report on Form 
10-K.

          (c)    STOCK OPTIONS.  In addition to stock options previously 
granted to Executive, in partial consideration for Executive's 
non-competition agreements, set forth herein, effective December 31, 1998, 
Executive shall be provided with additional options to purchase HCC shares as 
follows:

          (1)    On January 7, 1998, an option to acquire 100,000 shares, 
exercisable at a price of $16.50 per share and vesting at 20% per year 
beginning on December 31, 1998 and for each of the four years thereafter;

          (2)    For each year beginning with the year ending December 31, 
1999, of Executive's employment hereunder; 

          10,000 shares if, on such December 31, the price of the HCC Common 
          Stock has increased since the previous January 1, by an amount that 
          is greater than or equal to 10%, but less than 15%;

          15,000 shares if, on such December 31, the price of the HCC Common 
          Stock has increased since the previous January 1, by an amount that 
          is greater than or equal to 15%, but less than 20%;

          20,000 shares if, on such December 31, the price of the HCC Common 
          Stock has increased since the previous January 1, by an amount that 
          is greater than or equal to 20%, but less than 25%; and

          25,000 shares if, on such December 31, the price of the HCC Common 
          Stock has increased since the previous January 1, by an amount that 
          is greater than or equal to 25%.

          Each of such options set forth in this subparagraph (ii) shall be 
          priced at the average of the closing prices of HCC shares for the 
          month of December of the year of the grant and shall vest 
          immediately.  For purposes of this Subparagraph, the granting of 
          any option shall not be pro-rated if the criteria set forth herein 
          are not achieved in full.

          (d)    EXPENSES.  During the Basic Term, Executive shall be 
entitled to receive prompt reimbursement for all reasonable expenses incurred 
by him in accordance with the policies and procedures established by the 
Compensation Committee for the Company's senior executive officers in 
performing services hereunder, provided that Executive properly accounts 
therefor in accordance with Company policy.

          (e)    OTHER BENEFITS.  Executive shall be entitled to participate 
in or receive 

EMPLOYMENT AGREEMENT - Page 3
<PAGE>

benefits under any compensatory employee benefit plan or other arrangement 
made available by the Company now or in the future to its senior executive 
officers, subject to and on a basis consistent with the terms, conditions, 
and overall administration of such plan or arrangement.  Nothing paid to 
Executive under any plan or arrangement presently in effect or made available 
in the future shall be deemed to be in lieu of the Base Salary payable to 
Executive pursuant to Paragraph (a) of this Section.  The Company shall not 
make any changes in any employee benefit plans or other arrangements in 
effect on the date hereof or subsequently in effect in which Executive 
currently or in the future participates (including, without limitation, each 
pension and retirement plan, supplemental pension and retirement plan, 
savings and profit sharing plan, stock or unit ownership plan, stock or unit 
purchase plan, stock or unit option plan, life insurance plan, medical 
insurance plan, disability plan, dental plan, health and accident plan, or 
any other similar plan or arrangement) that would adversely affect 
Executive's rights or benefits thereunder, unless such change occurs pursuant 
to a program applicable to substantially all executives of the Company and 
does not result in a proportionately greater reduction in the rights of or 
benefits to Executive as compared with any other executive of the Company.

          (f)    VACATIONS.  Executive shall be entitled to twenty five (25) 
paid vacation days per year during the Basic Term.  There shall be no 
carryover of unused vacation from year to year.  For purposes of this 
Paragraph, weekends shall not count as vacation days, and Executive shall 
also be entitled to all paid holidays and personal days given by the Company 
to its senior executive officers.

          (g)    PERQUISITES.  Executive shall be entitled to receive the 
perquisites and fringe benefits appertaining to an executive officer of HCC 
in accordance with any practice established by the Compensation Committee.  
Notwithstanding, and in addition to, any perquisites to which Executive is 
entitled pursuant to the preceding sentence, Executive shall:  (i) have use 
of a 1998 Mercedes SEL automobile, and the Company shall pay all expenses 
related to Executive's use of such car, including gasoline, insurance, and 
maintenance; (ii) be allowed to travel on business utilizing first class 
passage (whether domestic or international); (iii) receive annual club dues 
for the Houston City Club, the Country Club of Fairfield, and Lochinvar Golf 
Club; and (iv) receive a total of $1,000,000 term life insurance (which shall 
be an addition to the standard benefits provided to Executive under the 
Company's group life insurance program that covers officers).

          (h)    PRORATION.  Any payments or benefits payable to Executive 
hereunder in respect of any calendar year during which Executive is employed 
by the Company for less than the entire year, unless otherwise provided in 
the applicable plan or arrangement, shall be prorated in accordance with the 
number of days in such calendar year during which he is so employed.  
Notwithstanding the foregoing, any payments pursuant to Paragraphs 4(c) or 
4(d) of this Agreement shall not be subject to proration.

    5.    TERMINATION.

delivered to Executive written notice from the Board supplying the 
particulars of Executive's acts or omissions that the Board believes 
constitute Cause, a reasonable period of time (not less than 30 days) has 
been given to Executive after such notice to either cure the same or to meet 
with the Board, with his attorney if so desired by Executive, and following 
which the Board by action of not less than two-thirds of its members

consolidation of the Company with any other corporation, other than a merger 
or consolidation (a) in which a majority of the directors of the surviving 
entity were directors of the Company prior to such consolidation or merger, 
and (b) which would result in the voting securities of the Company 
outstanding immediately prior thereto continuing to represent (either by 
remaining outstanding or by being changed into voting securities of the 
surviving entity) more than 50% of the combined voting power of the voting 
securities of the surviving entity outstanding immediately after such merger 
or consolidation; or

                 (iv)   The shareholders approve a plan of complete 
liquidation of the Company or an agreement for the sale or disposition by the 
Company of all or substantially all of the Company's assets.

Executive's duties with the Company on a full-time basis for 180 consecutive 
days, or 180 days in a 365 day period, as a result of incapacity due to 
mental or physical illness which results in the Executive being unable to 
perform the essential functions of his position, with or without reasonable 
accommodation.

          (4)    A "GOOD REASON" shall mean any of the following (without 
Executive's express written consent):

                 (i)    Following a Change of Control, a material alteration 
    in the nature or status of Executive's title, duties or responsibilities, 
    or the assignment of duties or responsibilities inconsistent with 
    Executive's status, title, duties and responsibilities;

                 (ii)   A failure by the Company to continue in effect any 
    employee benefit plan in which Executive was participating, or the taking 
    of any action by the Company that would adversely affect Executive's 
    participation in, or materially reduce Executive's benefits under, any such 
    employee benefit plan, unless such failure or such taking of any action 
    adversely affects the senior members of corporate management of the Company 
    generally to the same extent;

                 (iii)  A relocation of the Company's principal executive 
    offices, or Executive's relocation to any place other than the principal 
    executive offices, exceeding a distance of fifty (50) miles from the 
    Company's current executive office located in Houston, Texas, except for 
    reasonably required travel by Executive on the Company's business;

                 (iv)   Any material breach by the Company of any provision

EMPLOYMENT AGREEMENT - Page 6
<PAGE>

    performance of this Agreement by any successor (by merger, consolidation, 
    or otherwise) or assign of the Company.

    However, Good Reason shall exist with respect to an above specified matter 
    only if such matter is not corrected by the Company within thirty (30) days 
    of its receipt of written notice of such matter from Executive, and in no 
    event shall a termination by Executive occurring more than ninety (90) days 
    following the date of the event described above be a termination for Good 
    Reason due to such event.

              (5)    "TERMINATION DATE" shall mean the date Executive is 
terminated for any reason pursuant to this Agreement.

          (b)    TERMINATION WITHOUT CAUSE OR FOR GOOD REASON:  BENEFITS.  In 
the event there is a termination by the Company without Cause, or if 
Executive terminates for Good Reason (a "Termination Event"), this Agreement 
shall terminate and Executive shall be entitled to the following severance 
benefits:

              (1)    For a period of twelve (12) months after the Termination 
    Date (unless the remainder of the Basic Term is less than twelve (12) 
    months, in which case, for an amount of time equal to the remainder of the 
    Basic Term), Base Salary (as defined in Paragraph 3(a), at the rate, and 
    payable quarterly unless such termination is by the Company without Cause, 
    in which event such amount of Base Salary shall be paid in a lump sum 
    within ten (10) days of the Termination Event.

              (2)    If there is a Change of Control or if there is a 
    termination by the Company without Cause or by Executive for Good Reason, 
    any stock options and other stock-related grants ("Stock Awards") which 
    Executive has received under any of the HCC stock plans shall vest 
    immediately; provided, however, that the right to receive options 
    referenced in Paragraph 3(c)(2) above shall terminate upon termination from 
    employment for any reason, and further, if there is a termination for Good 
    Reason, or by the Company other than for Cause, all options shall be 
    exercisable for one year or the remainder of their term, whichever is less. 

              (3)    To the extent not theretofore paid or provided, the 
    Company shall timely pay or provide to Executive any other amounts or 
    benefits required to be paid or provided or which Executive is eligible to 
    receive under any plan, program, policy or practice, or contract or 
    agreement of the Company and its affiliated companies for the period of time
    equal to the remainder of the Basic Term (such other amounts and benefits 
    shall be hereinafter referred to as the "Other Benefits").  Without 
    limiting the preceding sentence, through December 31, 2002 the Company, at 
    its sole expense, shall continue to provide (through its own plan and/or 
    individual policies) Executive (and Executive's dependents) with health 
    benefits no less favorable than the group health plan benefits provided 
    during such period to any senior executive officer of the Company or any 
    affiliated company (to the extent any such coverage or benefits are taxable 
    to Executive 

EMPLOYMENT AGREEMENT - Page 7
<PAGE>

    by reason of being provided under a self-insured health plan of the Company 
    or an affiliate, the Company shall make Executive "whole" for the same on 
    an after-tax basis).  In any event the Other Benefits provided for pursuant 
    to this Paragraph shall be secondary to any benefits and coverage Executive 
    (or his dependents) receive from another employer.

              (4)    If Executive receives any payments whether or not pursuant 
    to this Agreement which are subject to an excise tax imposed under Section 
    4999 of the Internal Revenue Code of 1986, as amended, or any similar tax 
    imposed under federal, state, or local law (collectively, "Excise Taxes"), 
    the Company shall pay to Executive (on or before the date on which the 
    Company is required to withhold such Excise Taxes), 1) an additional amount 
    equal to all Excise Taxes then due and payable, and 2) the amount necessary 
    to defray Executive's increased (federal, state, and local) tax liability 
    arising due to payment of the amount specified in this Subsection (4) which 
    shall include any costs and expenses, including penalties and interest 
    incurred by Executive in connection with any audit, proceedings, etc. 
    related to the payment of such Excise Taxes or this payment.  For purposes 
    of calculating the amount payable to Executive under this Paragraph, the 
    federal and state income tax rates used shall be the highest marginal 
    federal and state rates applicable to ordinary income in Executive's state 
    of residence, taking into account any federal income tax deductions or 
    credits available to Executive for state income taxes.  The Company shall 
    cause its independent auditors to calculate such amount and provide 
    Executive a copy of such calculation at least ten (10) days prior to the 
    date specified above for payment of such amount.  It is the intent of the 
    Parties that this Subsection (4) shall place Executive in the same net 
    after-tax position Executive would have been in had no payment been subject 
    to an Excise Tax and, notwithstanding anything herein to the contrary, it 
    shall be construed to effectuate said result;

              (5)    All accrued compensation and unreimbursed expenses through 
    the Termination Date.  Such amounts shall be paid to Executive in a lump 
    sum in cash within thirty (30) days after the Termination Date; and

              (6)    Executive shall be free to accept other employment during 
    such period, and there shall be no offset of any employment compensation 
    earned by Executive in such other employment during such period against 
    payments due Executive under this Paragraph (4) and there shall be not 
    offset in any compensation received from such other employment against the 
    Base Salary set forth above.

          (c)    TERMINATION IN EVENT OF DEATH:  BENEFITS.  If Executive's 
employment is terminated by reason of Executive's death during the Basic 
Term, this Agreement shall terminate without further obligation to 
Executive's legal representatives under this Agreement, other than for 
payment of all accrued compensation, unreimbursed expenses, the timely 
payment or provision of Other Benefits through the date of death, and, if 
such death occurs on or after October 1 of any year, such cash or stock bonus 
as Executive would otherwise have been awarded in such year if Executive's 
death had not occurred.  Such amounts shall be paid to 

EMPLOYMENT AGREEMENT - Page 8
<PAGE>

Executive's estate or beneficiary, as applicable, in a lump sum in cash 
within ninety (90) days after the date of death.  With respect to the 
provision of Other Benefits, the term Other Benefits as used in this 
Paragraph 4(c) shall include, without limitation, and Executive's estate 
and/or beneficiaries shall be entitled to receive, benefits at least equal to 
the most favorable benefits provided by the Company to the estates and 
beneficiaries of other executive level employees of the Company under such 
plans, programs, practices, and policies relating to death benefits, if any, 
as in effect with respect to other executives and their beneficiaries at any 
time during the 120-day period immediately preceding the date of death.  
Additionally, all Stock Awards for which Executive would have been eligible 
had he completed the Basic Term (except as set forth in Paragraph 4(b)(2)), 
shall be accelerated, and Executive's estate or beneficiary shall be vested 
in such Stock Awards as of the date of Executive's termination.

          (d)    TERMINATION IN EVENT OF DISABILITY:  BENEFITS.  If 
Executive's employment is terminated by reason of Executive's Disability 
during the Basic Term, this Agreement shall continue in full force for a 
period of one (1) year following such Disability and if such Disability 
occurs on or after October 1 of any year Executive shall be entitled to the 
same cash or stock bonus in such year that Executive would have been awarded 
if such Disability had not occurred. Following such one (1) year period, this 
Agreement shall continue in full force except that (a) the Base Salary shall 
be reduced by 50% and (b) Executive shall not be entitled to any subsequent 
cash or stock bonuses.  In addition, all outstanding Stock Awards shall vest 
immediately upon such termination due to Disability.

          (e)    VOLUNTARY TERMINATION BY EMPLOYEE AND TERMINATION FOR CAUSE: 
BENEFITS. Executive may terminate his employment with the Company without 
Good Reason by giving written notice of his intent and stating an effective 
Termination Date at least ninety (90) days after the date of such notice; 
provided, however, that the Company may accelerate such effective date by 
paying Executive through the proposed Termination Date and also vesting 
awards that would have vested but for this acceleration of the proposed 
Termination Date.  Upon such a termination by Executive or upon termination 
for Cause by the Company, this Agreement shall terminate, and the Company 
shall pay to Executive all accrued compensation, unreimbursed expenses and 
the Other Benefits through the Termination Date.  Such amounts shall be paid 
to Executive in a lump sum in cash within thirty (30) days after the date of 
termination.

          (f)    DIRECTOR POSITIONS.  Executive agrees that upon termination 
of employment, for any reason, at the request of the Chairman of the Board, 
he will immediately tender his resignation from any and all Board positions 
held with the Company and/or any of its subsidiaries and affiliates.

    6.    NON-COMPETITION, NON-SOLICITATION, AND CONFIDENTIALITY.  Executive 
recognizes and agrees that the benefit of not being employed at-will, is 
provided in consideration for, among other things, the agreements contained 
in this Section as well as the Stock Options granted to Executive pursuant to 
this Agreement.  The Company agrees that while employed pursuant to this 
Agreement, Executive will be provided with confidential information of 
Company; specialized training on how to perform his duties; and contact with 
the Company's customers and 

EMPLOYMENT AGREEMENTS - Page 9
<PAGE>

potential customers.  Furthermore, in the event Executive is terminated 
without Cause, or terminates for Good Reason, and more than one (1) year 
remains on the existing Basic Term, then Executive shall receive additional 
consideration in an amount equal to the quotient of the Base Salary divided 
by 12, which shall thereupon be multiplied by the number of months remaining 
in the Basic Term minus 12 months, and which shall be paid in one lump sum 
within ten (10) days of such termination.

    In consideration of all of the foregoing, Executive agrees as follows:

          (a)    NON-COMPETITION DURING EMPLOYMENT.  Executive agrees during 
the Basic Term he will not compete with the Company by engaging in the 
conception, design, development, production, marketing, or servicing of any 
product or service that is substantially similar to the products or services 
which the Company provides, and that he will not work for, in any capacity, 
assist, or become affiliated with as an owner, partner, etc., either directly 
or indirectly, any individual or business which offers or performs services, 
or offers or provides products substantially similar to the services and 
products provided by Company.

          (b)    CONFLICTS OF INTEREST.  Executive agrees that during the 
Basic Term, he will not engage, either directly or indirectly, in any 
activity (a "Conflict of Interest") which might adversely affect the Company 
or its affiliates, including ownership of a material interest in any 
supplier, contractor, distributor, subcontractor, customer or other entity 
with which the Company does business or accepting any material payment, 
service, loan, gift, trip, entertainment, or other favor from a supplier, 
contractor, distributor, subcontractor, customer or other entity with which 
the Company does business, and that Executive will promptly inform the 
Chairman of the Company as to each offer received by Executive to engage in 
any such activity.  Executive further agrees to disclose to the Company any 
other facts of which Executive becomes aware which might in Executive's good 
faith judgment reasonably be expected to involve or give rise to a Conflict 
of Interest or potential Conflict of Interest.

          (c)    NON-COMPETITION AFTER TERMINATION.  Executive agrees that 
Executive shall not, at any time during the period of two (2) years after the 
termination of the Basic Term, for any reason, within any of the markets in 
which the Company has sold products or services or formulated a plan to sell 
products or services into a market during the last twelve (12) months of 
Executive's employ or which the Company enters into within three (3) months 
thereafter, engage in or contribute Executive's knowledge to any work which 
is competitive with or similar to a product, process, apparatus, service, or 
development on which Executive worked or with respect to which Executive had 
access to Confidential Information while employed by the Company; provided, 
however, this Paragraph (c) shall not operate to prevent Executive from 
engaging in retail insurance or re-insurance activities during such two-year 
period to the extent such activities do not compete or permit any other 
person or entity to compete with any business the Company or any of its 
subsidiaries or affiliated companies were engaged in at the time of such 
termination or which the Company enters into within three (3) months 
thereafter.  Following the expiration of said two (2) year period, Executive 
shall continue to be obligated under the Confidential Information Paragraph 
of this Agreement not to use or to disclose Confidential Information of 

EMPLOYMENT AGREEMENT - Page 10
<PAGE>

the Company so long as it shall not be publicly available.  It is understood 
that the geographical area set forth in this covenant is divisible so that if 
this clause is invalid or unenforceable in an included geographic area, that 
area is severable and the clause remains in effect for the remaining included 
geographic areas in which the clause is valid.

          (d)    NON-SOLICITATION OF CUSTOMERS.  Executive further agrees 
that for a period of two (2) years after the termination of the Basic Term, 
he will not solicit or accept any business from any customer or client or 
prospective customer or client with whom Executive dealt or solicited while 
employed by Company during the last twelve (12) months of his employment.

          (e)    NON-SOLICITATION OF EMPLOYEES.  Executive agrees that for 
the duration of  the Basic Term, and for a period of two (2) years after the 
termination of the Basic Term, he will not either directly or indirectly, on 
his own behalf or on behalf of others, solicit, attempt to hire, or hire any 
person employed by Company to work for Executive or for another entity, firm, 
corporation, or individual.

          (f)    CONFIDENTIAL INFORMATION.  Executive further agrees that he 
will not, except as the Company may otherwise consent or direct in writing, 
reveal or disclose, sell, use, lecture upon, publish or otherwise disclose to 
any third party any Confidential Information or proprietary information of 
the Company, or authorize anyone else to do these things at any time either 
during or subsequent to his employment with the Company.  This Section shall 
continue in full force and effect after termination of Executive's employment 
and after the termination of this Agreement.  Executive's obligations under 
this Paragraph with respect to any specific Confidential Information and 
proprietary information shall cease when that specific portion of the 
Confidential Information and proprietary information becomes publicly known, 
in its entirety and without combining portions of such information obtained 
separately.  It is understood that such Confidential Information and 
proprietary information of the Company include matters that Executive 
conceives or develops, as well as matters Executive learns from other 
employees of Company.  Confidential Information is defined to include 
information:  (1) disclosed to or known by the Executive as a consequence of 
or through his employment with the Company; (2) not generally known outside 
the Company; and (3) which relates to any aspect of the Company or its 
business, finances, operation plans, budgets, research, or strategic 
development.  "Confidential Information" includes, but is not limited to the 
Company's trade secrets, proprietary information, financial documents, long 
range plans, customer lists, employer compensation, marketing strategy, data 
bases, costing data, computer software developed by the Company, investments 
made by the Company, and any information provided to the Company by a third 
party under restrictions against disclosure or use by the Company or others.

          (g)    RETURN OF DOCUMENTS, EQUIPMENT, ETC.  All writings, records, 
and other documents and things comprising, containing, describing, 
discussing, explaining, or evidencing any Confidential Information, and all 
equipment, components, parts, tools, and the like in Executive's custody or 
possession that have been obtained or prepared in the course of Executive's 
employment with the Company shall be the exclusive property of the Company, 
shall 

EMPLOYMENT AGREEMENT - Page 11
<PAGE>

not be copied and/or removed from the premises of the Company, except in 
pursuit of the business of the Company, and shall be delivered to the 
Company, without Executive retaining any copies, upon notification of the 
termination of Executive's employment or at any other time requested by the 
Company.  The Company shall have the right to retain, access, and inspect all 
property of Executive of any kind in the office, work area, and on the 
premises of the Company upon termination of Executive's employment and at any 
time during employment by the Company to ensure compliance with the terms of 
this Agreement.

          (h)    REAFFIRM OBLIGATIONS.  Upon termination of his employment 
with the Company, Executive, if requested by Company, shall reaffirm in 
writing Executive's recognition of the importance of maintaining the 
confidentiality of the Company's Confidential Information and proprietary 
information, and reaffirm any other obligations set forth in this Agreement.

          (i)    PRIOR DISCLOSURE.  Executive represents and warrants that he 
has not used or disclosed any Confidential Information he may have obtained 
from Company prior to signing this Agreement, in any way inconsistent with 
the provisions of this Agreement.

          (j)    CONFIDENTIAL INFORMATION OF PRIOR COMPANIES.  Executive will 
not disclose or use during the period of his employment with the Company any 
proprietary or Confidential Information or Copyright Works which Executive 
may have acquired because of employment with an employer other than the 
Company or acquired from any other third party, whether such information is 
in Executive's memory or embodied in a writing or other physical form.

          (k)    BREACH.  Executive agrees that any breach of Paragraphs 
5(a), (c), (d), (e) or (f) above cannot be remedied solely by money damages, 
and that in addition to any other remedies Company may have, Company is 
entitled to obtain injunctive relief against Executive.  Nothing herein, 
however, shall be construed as limiting Company's right to pursue any other 
available remedy at law or in equity, including recovery of damages and 
termination of this Agreement and/or any payments that may be due pursuant to 
this Agreement.

          (l)    RIGHT TO ENTER AGREEMENT.  Executive represents and 
covenants to Company that he has full power and authority to enter into this 
Agreement and that the execution of this Agreement will not breach or 
constitute a default of any other agreement or contract to which he is a 
party or by which he is bound.

          (m)    EXTENSION OF POST EMPLOYMENT RESTRICTIONS.  In the event 
Executive breaches Paragraphs 5(b), (d), or (e) above, the restrictive time 
periods contained in those provisions will be extended by the period of time 
Executive was in violation of such provisions.

          (n)    ENFORCEABILITY.  The agreements contained in Section 5 are 
independent of the other agreements contained herein.  Accordingly, failure 
of the Company to comply with any of its obligations outside of this 
Paragraph do not excuse Executive from complying with the agreements 
contained herein.

EMPLOYMENT AGREEMENT - Page 12
<PAGE>

          (o)    SURVIVABILITY.  The agreements contained in Paragraph 
5(c)-(g) shall survive the termination of this Agreement for any reason.

    7.    ASSIGNMENT. The Company may assign this Agreement only to a 
successor (whether direct or indirect, by purchase, merger, consolidation or 
otherwise) to all or substantially all of the business and assets of the 
Company provided such successor expressly agrees in writing reasonably 
satisfactory to Executive to assume and 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 and assignment had taken place.  Failure of the 
Company to obtain such written agreement prior to the effectiveness of any 
such succession shall be a material breach of this Agreement.

    8.    BINDING AGREEMENT.  Executive understands that his obligations 
under this Agreement are binding upon Executive's heirs, successors, personal 
representatives, and legal representatives.

    9.    NOTICES.  All notices pursuant to this Agreement shall be in 
writing and sent certified mail, return receipt requested, addressed as set 
forth below, or by delivering the same in person to such party, or by 
transmission by facsimile to the number set forth below (which shall not 
constitute notice).  Notice deposited in the United States Mail, mailed in 
the manner described hereinabove, shall be effective upon deposit.  Notice 
given in any other manner shall be effective only if and when received:

    11.    SEVERABILITY.  If any provision of this Agreement is determined to 
be void, invalid, unenforceable, or against public policy, such provisions 
shall be deemed severable from the Agreement, and the remaining provisions of 
the Agreement will remain unaffected and in full force and effect.

    12.    ARBITRATION.  In the event any dispute arises out of Executive's 
employment with the Company, or separation therefrom, which cannot be 
resolved by the Parties to this Agreement, such dispute shall be submitted to 
final and binding arbitration.  The arbitration shall be conducted in 
accordance with the National Rules for the Resolution of Employment Disputes 
of the American Arbitration Association ("AAA").  If the Parties cannot agree 
on an arbitrator, a list of seven (7) arbitrators will be requested from AAA, 
and the arbitrator will be selected using alternate strikes with Executive 
striking first.  The cost of the arbitration will be shared equally by 
Executive and Company; provided, however, the Company shall promptly 
reimburse Executive for all costs and expenses incurred in connection with 
any dispute in an amount up to, but not exceeding 20 percent of Executive's 
Base Salary unless such termination was for Cause in which event Executive 
shall not be entitled to reimbursement unless and until it is determined he 
was terminated other than for Cause.  Arbitration of such disputes is 
mandatory and in lieu of any and all civil causes of action and lawsuits 
either party may have against the other arising out of Executive's employment 
with Company, or separation therefrom.  Such arbitration shall be held in 
Houston, Texas.

    13.    ENTIRE AGREEMENT.  The terms and provisions contained herein shall 
constitute the entire agreement between the parties with respect to 
Executive's employment with Company during the time period covered by this 
Agreement.  This Agreement replaces and supersedes any and all existing 
Agreements entered into between Executive and the Company relating generally 
to the same subject matter, if any, and shall be binding upon Executive's 
heirs, executors, administrators, or other legal representatives or assigns.

    14.    MODIFICATION OF AGREEMENT.  This Agreement may not be changed or 
modified or released or discharged or abandoned or otherwise terminated, in 
whole or in part, except by an instrument in writing signed by the Executive 
and an officer or other authorized executive of Company.

    15.    UNDERSTAND AGREEMENT.  Executive represents and warrants that he 
has read and understood each and every provision of this Agreement, and 
Executive understands that he has the right to obtain advice from legal 
counsel of choice, if necessary and desired, in order to interpret any and 
all provisions of this Agreement, and that Executive has freely and 
voluntarily entered into this Agreement.

    16.    GOVERNING LAW.  This Agreement shall be governed by and construed 
in accordance with the laws of the State of Texas.
