ITEM 1. BUSINESS
 
  Certain terms used below are defined in the "Glossary of Selected Insurance
Terms" appearing on page 20.
 
 General
 
  ACE Limited ("ACE") is a holding company incorporated with limited liability
under the Cayman Islands Companies Law and maintains its principal business
office in Bermuda. The Company, through its Bermuda-based operating
subsidiaries, A.C.E. Insurance Company, Ltd. ("ACE Insurance"), Corporate
Officers & Directors Assurance Ltd. ("CODA") and Tempest Reinsurance Company
Limited ("Tempest"), provides insurance and reinsurance for a diverse group of
international clients. In addition, the Company provides funds at Lloyd's of
London ("Lloyd's") to support underwriting by syndicates managed by Methuen
Underwriting Limited ("MUL"). The term "the Company" refers to ACE and its
subsidiaries excluding the Lloyd's operations carried out by Methuen Group
Limited ("Methuen") and its subsidiaries and Ockham Worldwide Holdings plc
("Ockham Worldwide") and its subsidiaries (see "Recent Developments").
 
  The Company's long-term business strategy focuses on achieving underwriting
profits and providing value to its clients and shareholders through the
utilization of its growing capital base within the insurance and reinsurance
markets. As part of this strategy, the Company diversified its product
portfolio from excess liability insurance and directors and officers liability
insurance to accommodate the needs of its expanding, global client base of
multinational corporations by adding satellite insurance, aviation insurance,
excess property insurance and financial lines products during 1994 and 1995.
This diversification added balance to the risk of the existing portfolio of
insurance products and enhanced the Company's overall profit potential while
utilizing its existing capital base. The Company continued its strategic
diversification with the acquisitions in March 1996 of Methuen Group Limited
("Methuen"), the holding company for MUL, a leading Lloyd's managing agency,
and in July 1996 of Tempest, a leading Bermuda-based property catastrophe
reinsurer. The acquisition of Tempest provided the Company with a unique
opportunity to expand into the property catastrophe reinsurance business
through an established and well known reinsurance company.
 
  The following table sets forth the percentage of net premiums written by
line of business for each of the years ended September 30, 1996, 1995 and
1994:

(1) Tempest was acquired on July 1, 1996 and thus net premiums written for
    Tempest only relate to the three month period since acquisition.
 
 Recent Developments
 
  On July 1, 1996, the Company completed the acquisition of Tempest. Tempest
underwrites property catastrophe reinsurance on a worldwide basis, emphasizing
excess layer coverages, and has large aggregate
 
                                       1
<PAGE>
 
exposures to man-made and natural disasters. The short-tail nature of the
property catastrophe business and shorter loss payout patterns complement the
generally longer-tail nature of the Company's existing product lines.
 
  On March 27, 1996, the Company acquired a controlling interest in Methuen.
On November 26, 1996, the Company acquired the remaining 49 percent interest
in Methuen. MUL manages six syndicates with total underwriting capacity for
the 1996 year of account of (Pounds)366 million (approximately $555 million).
For the 1996 year of account, the Company has, through a corporate subsidiary,
ACE Capital Limited ("ACE Capital"), provided funds at Lloyd's of
(Pounds)12.25 million (approximately $18 million), which was primarily in the
form of a letter of credit, supporting (Pounds)24.5 million (approximately $37
million) of underwriting capacity on syndicates managed by MUL. For the 1997
year of account, the Company has agreed to provide funds at Lloyd's of
approximately (Pounds)62 million (approximately $93 million) to support up to
approximately (Pounds)124 million (approximately $186 million) of underwriting
capacity on syndicates managed by MUL (see "Lloyd's of London").
 
  On November 26, 1996 the Company acquired Ockham Worldwide Holdings PLC
("Ockham Worldwide"), a wholly owned subsidiary of Ockham Holdings PLC. Ockham
Worldwide owns two Lloyd's managing agencies, ACE London Aviation Limited
("ALVL") (formerly Ockham Sturge Aviation Agency Ltd.) and ACE London
Underwriting Limited ("ALUL") (formerly Ockham Worldwide Agency Ltd). Together
these two agencies manage seven syndicates with total underwriting capacity
for the 1996 year of account of (Pounds)349 million (approximately $524
million). Ockham Worldwide also owns a Lloyd's corporate member which provides
funds at Lloyd's to support underwriting on these syndicates. The Company
expects to provide approximately (Pounds)15 million (approximately $23
million) of underwriting capacity to the syndicates managed by Ockham
Worldwide for the 1997 year of account.
 
 Insurance Operations
 
  The Company, through ACE Insurance and CODA, provides property and casualty
insurance coverage, including excess liability insurance, directors and
officers liability insurance, satellite insurance, aviation insurance, excess
property insurance and financial lines products, to industrial, commercial and
other enterprises.
 
  The nature of the insurance coverages provided by the Company are generally
expected to result in low frequency but high severity of individual losses.
This loss pattern is particularly evident in the Company's excess liability
insurance due to the high attachment points and large limits offered. The
Company does purchase limited excess of loss clash reinsurance with respect to
its excess liability policies and has also purchased reinsurance designed to
limit its exposure on the satellite, aviation and excess property lines of
business.
 
  At September 30, 1996 approximately 73 percent of the Company's written
premiums came from North America with approximately 20 percent coming from the
United Kingdom and continental Europe and approximately 7 percent from other
countries.
 
 Excess Liability
 
  The Company seeks to provide to the world's largest industrial enterprises
the highest layer of excess liability coverage in their insurance programs and
requires that at least a portion of its coverage be the highest layer in a
policyholder's insurance program. The Company writes excess liability
coverage, on an occurrence first reported stand alone form, generally in
excess of a minimum attachment point of $100 million per occurrence and with a
minimum limit of $10 million and a maximum limit of $200 million per
occurrence, subject to an annual aggregate limit in the same amount for all
covered occurrences of which notice is given during such year. Effective on or
after December 15, 1994 the Company has imposed an annual aggregate sublimit
for integrated occurrences of $100 million for all new and renewal business
that purchases limits greater than $100 million. During 1994, the Company
reduced the minimum attachment point to $50 million (or the
 
                                       2
<PAGE>
 
foreign currency equivalent) from $100 million for certain classes of non-U.S.
domiciled excess liability risks. In this instance, the Company offers limits
up to twice the reduced attachment point with a minimum limit of $25 million.
 
  In general, the excess liability policies cover occurrences causing
unexpected and unintended personal injury, property damage and/or advertising
liability arising from events or conditions which commence at or subsequent to
the inception date (or retroactive date, if applicable, but typically not prior
to November 1, 1985), provided proper notice is given to the Company during the
term of the policy or any applicable discovery period. Unlike traditional
insurance policy forms, disputes under the Company's policies are required to
be settled by arbitration in Bermuda or London, depending on the policy. Either
the Bermuda Arbitration Act of 1986, as amended, or the English Arbitration Act
of 1950, as amended, governs the arbitration.
 
  The Company maintains excess of loss clash reinsurance on a calendar year
basis which provides the Company with certain protection from losses arising
from a single set of circumstances (occurrence) under more than one excess
liability insurance policy. The clash reinsurance agreements do not cover all
occurrences covered by the Company's policies and, in particular, do not cover
integrated occurrences involving one insured or similar occurrences in which
multiple insureds are found liable (e.g., similar defective products
manufactured or sold by multiple insureds).
 
 Directors and Officers Liability
 
  The Company offers up to $75 million of directors and officers liability
insurance with a maximum of $50 million being provided for corporate
reimbursement coverage. The Company believes this to be the largest amount of
directors and officers liability insurance available from a single underwriting
source. The directors and officers liability insurance is written on a claims
made form and is provided to large industrial corporations, not-for-profit
corporations, financial institutions and others. As with the excess liability
form, disputes are required to be settled by arbitration in Bermuda or London.
 
 Satellite
 
  The Company began satellite insurance operations in February 1994. Until
February 15, 1996, the Company offered separate limits of up to $25 million per
risk for launch insurance, including ascent to orbit and/or initial testing,
and up to $25 million per risk for in-orbit insurance. This risk was fully
retained by the Company. Effective for all business written on or after
February 15, 1996, the Company has entered into a surplus treaty arrangement,
which provides for up to $25 million of reinsurance for each risk. This
reinsurance arrangement has enabled the Company to raise the gross limits
offered for satellite insurance to $50 million per risk. The Company believes
its commitment represents one of the world's largest net lines. The Company
also believes that this stable capacity and the financial security offered by
the Company's asset base provide distinct competitive advantages and have
resulted in the Company becoming a significant provider of satellite insurance.
 
  Satellite insurance falls within a small, well defined market characterized
by a limited number of brokers, underwriters and international clients. There
are also a limited number of satellite and launch vehicle manufacturers in the
world. The growing worldwide demand for satellite communications capabilities
by both governments and private enterprises has resulted in an increase in the
number of satellites per annum requiring launch and/or in-orbit insurance
coverage. The typical satellite insurance policy is written on a quota-share
basis, rather than on an excess of loss basis. The insured value of a
commercial satellite now ranges from approximately $150 million to $300
million.
 
  The Company is at risk, under the terms of a typical launch insurance policy,
from the point of intentional ignition of the launch vehicle and for a period
of approximately 90 to 365 days to allow for initial operations of the
satellite. In-orbit coverage incepts on termination of the launch insurance
policy, which usually occurs on completion of the initial operations testing of
the satellite. In-orbit insurance is generally written on an annual basis,
although policy periods can be as long as 36 months.
 
                                       3

 Financial Lines
 
  The Company introduced its financial lines product group in January 1995.
Financial lines utilizes transactions which combine the concepts of finance
with the principles of insurance. Typically, clients purchasing these products
are seeking insurance or reinsurance for exposures which are difficult to
place because of limited or nonexistent capacity or inefficient terms or
pricing being provided by traditional insurance markets. Alternatively, they
may use these insurance or reinsurance products to cover loss exposures which
are not efficiently handled by current products available.
 
  Unlike certain traditional insurance, each financial lines contract is
individually tailored to meet the needs of the insured. Financial Lines
programs typically have the following common characteristics: multi-year
contract terms; broad coverage that includes stable capacity and pricing for
the insured; insured participation in the results of their own loss
experience; and aggregate limits. The specific product types offered by
financial lines include the various forms of finite risk insurance. Examples
of finite risk products include the combination of self-insurance with an
excess program, the combination of various coverages subject to a single
retention and insured limit or programs that insure large loss exposure or a
portfolio of losses over a period of years. Other product types offered are
specialty insurances which cover financial exposures or involve financial
instruments.
 
  Financial lines products were created by the need to service the more
complex risks of today's corporations. The Company anticipates drawing on the
strong franchise the Company maintains with its current client base by
providing a policy which will further enhance a client's risk management
program. Using both insurance and reinsurance brokers and investment bankers,
it also anticipates attracting new clients for the Company.
 
  The Company believes it has a competitive advantage in the marketplace
because of the financial strength of the Company and its ability to offer
significant risk transfer while still allowing the insured to retain some of
its own exposures. Risk transfer is important to the insured thereby enabling
it to meet the accounting and regulatory requirements related to the purchase
of insurance or reinsurance.
 
  Financial lines has a flexible approach to limits offered, attachment points
and coverages provided primarily due to the risk sharing feature and use of
funding mechanisms which are generally included in the contract. Each contract
is unique because it is tailored to the insurance needs, specific loss history
and financial strength of the client. Premium volume, as well as the number of
contracts written, can vary significantly from period to period due to the
nature of the contracts being written. Profit margins may vary from contract
to contract depending on the amount of underwriting risk and investment risk
assumed on each contract.
 
 Aviation
 
  The Company commenced writing aviation insurance in April 1995 and offers
limits of up to $100 million per insured, with no minimum attachment point.
The Company reduces its net exposure per policy to approximately $50 million
with a dedicated reinsurance program. Classes of business written include
aviation product liability, aviation manufacturers (including hull and all
risks and products liability); aviation refuellers; and airport and airport
contractors, together with certain aircraft risks.
 
  Generally, the Company will write aircraft liability in conjunction with one
or more of the other aviation products, and where the aircraft (owned or non-
owned) is used for corporate purposes. Coverage will include third party
bodily injury, property damage and passenger legal liability.
 
 Excess Property
 
  The Company entered the excess property insurance business in June 1995.
Primary target markets are chemical, energy, electronics, forest products,
heavy manufacturing, mineral, oil and gas, and utilities. Coverage is also
available to select manufacturing, industrial and institutional risks. Excess
property insurance coverage is offered with limits of up to $50 million per
risk, above a minimum attachment point of $25 million. In certain
 
                                       4
<PAGE>
 
circumstances, the Company uses reinsurance to establish the retained net
limit per risk. Attachment levels, terms and pricing for each risk are derived
from the Company's property underwriters' independent assessment of "probable
maximum loss", a benchmark of risk frequency and severity. The Company has
purchased catastrophe reinsurance to control the possible effects of
cumulative natural peril exposure.
 
 Marketing and Underwriting
 
  The Company, through ACE Insurance and CODA, markets its insurance products
through brokers and seeks to maintain a competitive advantage by providing
insurance coverages which require utilization of technical skills to
underwrite individual risks, emphasizing quality rather than volume of
business to obtain a suitable spread of risk. This enables the Company to
operate with a relatively small number of employees and, together with the
reduced costs of operating in a favorable regulatory and tax environment,
results in significantly lower administrative expenses relative to other
companies in the industry.
 
  Policyholders are obtained through non-U.S. insurance brokers who generally
receive a brokerage commission on any business accepted and bound by the
Company. The Company is not committed to accept any business from any
particular broker and brokers do not have the authority to bind the Company.
All policy applications (both for renewals and new policies) are subject to
approval and acceptance by the Company in its Bermuda office. A substantial
number of policyholders meet with the Company outside of the United States
each year to discuss their insurance coverage. The Company does not believe
that conducting its operations through its offices in Bermuda has materially
affected its underwriting and marketing activities to date.
 
  The Company receives business from approximately 75 non-U.S. brokers of
which 7 produced approximately 80 percent of the Company's business in 1996.
The following table sets forth the percentage of the Company's insurance
business placed in 1996, 1995 and 1994 through each broker placing more than
10 percent of the Company's business.

  At September 30, 1996, approximately 28 percent of the Company's
policyholders were not based in North America. The Company has experienced an
increase in the number of submissions in non-North American business as a
result of the activities of its London representative office since its opening
in September 1994 and expects further growth as a result of its activities.
The London representative office assists brokers throughout the United
Kingdom, the rest of Europe, the Middle East, South Africa, the Far East and
Australia in gaining access to the Company's underwriting capacity in Bermuda.
All underwriting activity continues to take place in Bermuda.
 
  The Company employs underwriting staff with substantial industry experience.
The underwriter's primary objective is to assess the potential for an
underwriting profit, a process complicated in some cases by the limited amount
of data for claims which would have been covered by the Company's policy form
and which would have exceeded its policy's attachment point. The risk
assessment process undertaken by the Company involves a comprehensive analysis
of historical data and estimates of future value of losses which may not be
evident in the historical data. The factors which the Company considers
include the type of risk, the attachment point and coverage limits, the type,
size, complexity and location of the potential insureds operations, financial
data, the industry in which the potential insured operates, details of the
underlying insurance coverage provided, loss history and future corporate
plans.
 
 Competition
 
  Competitive forces in the international property and casualty insurance
business are substantial. Results are a function of underwriting and
investment performance, direct costs associated with the delivery of insurance
 
                                       5
<PAGE>
 
products, including the costs of regulation, the frequency and severity of
both natural and man-made disasters, as well as inflation (actual, social and
judicial), which impact loss costs. Decisions made by insurers concerning
their mix of business (offering certain types of coverage but declining to
write other types), their methods of operations and the quality and allocation
of their assets (including any reinsurance recoverable balances) will all
affect their competitive position. Some insurers continue to incur liability
for business written decades earlier covering gradual pollution and certain
product liability exposures. The relative size and reputation of insurers may
influence purchasing decisions of present and prospective customers and will
contribute to both geographic and industrial sector market penetration.
Oversupply of available capital has historically had the effect of encouraging
competition and depressing prices. Capital accumulation to support large
excess liability policies and the availability of suitably experienced
underwriters are partial barriers to entry, but insurance pricing will
continue to be influenced by supply. The Company's competitive position in the
casualty insurance industry is influenced by all of these factors. The Company
believes it has a number of competitive advantages in the insurance products
which it provides. Among the advantages are its strong capital base, its
ability to market a number of insurance products to its existing client and
potential client base and its ability to be flexible in providing contracts
which extend coverage for periods in excess of one year.
 
  The Company believes that it is unique in that it offers up to $200 million
of excess liability coverage and that its coverage is generally the highest
layer of a client's insurance program. There are a small number of insurers
that compete with the Company, including American International Group, Inc.
("AIG"), several large European insurers, Exel Limited ("EXEL"), certain
Lloyd's syndicates and Starr Excess Liability Insurance Co. Ltd. ("Starr").
The Company has continued to experience increased competition during 1996 in
this line of business.
 
  There is a small group of dominant insurers in the directors and officers
liability insurance area and the Company faces strong competition in that area
from competitors such as Executive Risk Insurance Company, AIG, Chubb Group of
Insurance Cos., CNA, EXEL, certain Lloyd's syndicates and Starr. The Company
has continued to experience increased competition throughout fiscal 1996.
However, the Company has been successfully marketing its products through the
London representative office, resulting in a number of new non-North American
accounts.
 
  The Company believes that the available limits, stable capacity and
financial security offered by the Company provide a competitive advantage in
the satellite insurance market. There are currently a limited number of
underwriters available to service the satellite insurance market, however, the
amount of capacity available in the market place has grown substantially and
there now appears to be excess capacity in this market. The Company believes
that there will be continued demand for its services, as evidenced by
commitments already provided by the Company for future satellite insurance
coverage. Other major firms offering satellite coverage include Assicuraziona
Generali S.p.A., International Technology Underwriters, Inc., La Reunion
Aerienne, The Marchant Space Consortium, Munich Reinsurance and United States
Aviation Insurance Group.
 
  There are a number of companies in the insurance market which form the
competition for financial lines, including Centre Reinsurance (Bermuda)
Limited and several of the major international insurance companies, such as
AIG and American Reinsurance. The demand for individually tailored insurance
products, such as those offered by financial lines is growing due to the ever-
changing and more complex risks facing today's corporations. The Company
believes it has a competitive advantage in the marketplace because of the
financial strength of the Company and its ability to offer significant risk
transfer in its contracts while still allowing the insured to retain some of
its own exposures.
 
  In providing coverage for aviation insurance exposures, the Company faces
significant competition from a small number of specialty firms, including
certain Lloyd's syndicates and several large European insurers. The Company
believes that the limited number of underwriters available to service the
aviation insurance market, particularly in areas such as product manufacturers
liability and airport liability, and the commitment of significant capital to
this long-tail type of business are barriers to entry. The Company believes
that the demand for this type of specialty coverage is growing, as evidenced
by the volume of submissions received and the number of accounts written by
the Company to date.
 
                                       6

  There are a diverse number of companies providing excess property insurance
coverage for increasingly complex multi-site, multi-national risks. Although
the market is very competitive, the Company believes that it has several
competitive advantages in offering global excess "all risk" coverage,
including its experienced underwriting team, access to the latest technology
and analytical methods, a precise market focus and a capital base that is
unburdened by historic unprofitability and/or uncontrolled accumulation of
exposures.
 
  The Company expects that a significant portion of the future growth in most
of its lines of business will continue to come from new non-U.S. accounts.
Accordingly, the Company is promoting its products overseas, particularly to
large industrial companies in Latin America, Europe, the Middle East, South
Africa, Australia and the Far East.
 
  The Company has received a group rating of A (Excellent) from A.M. Best
Company, a leading insurance rating company ("A.M. Best"). The most current
rating covers the Company, together with its operating subsidiaries ACE
Insurance and CODA. A.M. Best assigns an A rating to companies which, in its
opinion, have demonstrated excellent overall performance when compared to the
standards established by A.M. Best and have a strong ability to meet their
obligations to policyholders over a long period of time. An A.M. Best rating
is based upon factors relevant to policyholders, agents and intermediaries and
are not directed toward the protection of investors. Such ratings are not
recommendations to buy, sell or hold securities.
 
 Reinsurance Operations
 
  The Company's reinsurance activities are principally conducted through
Tempest, its wholly owned subsidiary, which was acquired on July 1, 1996. In
addition, through ACE Insurance, the Company offers financial lines
reinsurance products (see discussion in "Insurance Operations") and
participates in the reinsurance of "First Line".
 
  The Company participates in the reinsurance of a program referred to as
"First Line" which provides financial guarantees required by the U.S. Coast
Guard to issue Certificates of Financial Responsibility, under the Oil
Pollution Act of 1990, to owners of vessels operating in U.S. waters. The
Company has purchased excess of loss reinsurance to limit its exposure in this
line.
 
  Tempest provides property catastrophe reinsurance worldwide to insurers of
commercial and personal property, typically under treaties having a duration
of one year. Property catastrophe reinsurance protects a ceding company
against an accumulation of losses covered by the insurance policies it has
issued arising from a common event or "occurrence." Ceding companies may
purchase reinsurance to achieve a number of results, including: reduction of
net exposure on individual risks or groups of risks, which enables the ceding
company to underwrite larger risks, or accept more business than its own
capital resources would ordinarily support; diversification of risks;
protection against the effect of major catastrophic losses, such as losses
involving an accumulation of single retentions; stabilization of a ceding
company's operating results by smoothing its loss experience to protect its
financial position; and maintenance by a ceding company of acceptable surplus,
reserve and other financial ratios.
 
  Tempest's property catastrophe reinsurance contracts cover unpredictable
natural or man-made disasters, such as hurricanes, windstorms, hail storms,
earthquakes, volcanic eruptions, conflagrations, freezes, floods, fires and
explosions. Tempest's predominant exposure under such coverage is to property
damage. However, other risks, such as business interruption may also be
covered when arising from a covered peril. In accordance with market practice,
Tempest's property catastrophe reinsurance contracts generally exclude certain
risks such as war, nuclear contamination, and radiation.
 
  Tempest underwrites reinsurance principally on an excess of loss basis, with
attachment points designed to minimize claims from relatively high frequency
and low severity events. During the ten month period ended
 
                                       7
<PAGE>
 
September 30, 1996, approximately 96 percent of premiums were written on an
excess of loss basis. Other property reinsurance written by Tempest on a
limited basis for select clients, includes proportional property and per risk
excess of loss treaty reinsurance. At September 30, 1996, Tempest had 233
programs in force with 200 clients.
 
  Tempest underwrites a substantial portion of its business in currencies
other than U.S. dollars and may from time to time experience exchange gains
and losses and incur significant underwriting losses in currencies other than
U.S. dollars. The following table sets forth the amount of Tempest's premiums
written allocated by territory of coverage:

 Marketing and Underwriting
 
  Tempest markets its reinsurance products worldwide through reinsurance
brokers. Tempest also opened a representative office in London, England in
August 1996. Tempest's underwriting team builds relationships with key brokers
and clients by explaining Tempest's approach and demonstrating responsiveness
to customer needs. Tempest's approach to the business of reinsurance takes a
long-term perspective. Management believes that continual strengthening of the
relationships between Tempest, its producing brokers and their clients will
continue to contribute to a stable portfolio necessary to achieve continuity.
By retaining clients, Tempest seeks to build up extensive knowledge of them
and gain additional insight to enable a more accurate assessment of their
exposures.
 
  Tempest receives business from approximately 40 brokers. The following table
sets forth the percentage of Tempest's business written through each broker
and its affiliates placing more than 10 percent of Tempest's business:

  Rates, limits, retention and other reinsurance terms and conditions are
generally established in a worldwide competitive market that evaluates
exposure and balances demand for property catastrophe coverage against the
available supply. Tempest believes it is perceived by the market as being a
"lead" reinsurer and is typically involved in the negotiation and quotation of
the terms and conditions of the majority of the contracts in which it
participates.
 
  Because Tempest underwrites property catastrophe reinsurance and has large
aggregate exposures to natural and man-made disasters, Tempest's claims
experience generally will involve infrequent events of great severity. Tempest
seeks to diversify its reinsurance portfolio to moderate the impact of this
severity. The principal means of diversification are by geographic coverage
and by varying attachment points and imposing coverage limits
 
                                       8
<PAGE>
 
per program. Tempest also establishes zonal accumulation limits to avoid
concentrations of risk within particular geographic areas.
 
  Tempest applies an underwriting process based on models that use exposure
data submitted by prospective reinsureds in accordance with requirements set
by Tempest's underwriters. The account review process includes an analysis of
exposures both by line of business and geographic location. The underwriting
models used by Tempest have been created and continue to be developed in-
house. Tempest believes that these risk analysis tools provide greater utility
and flexibility in comparison with external vendor catastrophe modeling
products, especially when confronted with unique exposures or non-standard
coverage.
 
  Tempest analyses its exposure in more detail using simulation modeling of
loss scenarios and their effects on Tempest's overall portfolio. This approach
enables Tempest to assess the portfolio risk, in particular to account for the
risk of a combination of multiple events worldwide in a single year.
 
 Competition
 
  The property catastrophe reinsurance industry is highly competitive. Tempest
competes worldwide with major U.S. and non-U.S. property catastrophe
reinsurers, other Bermuda-based property catastrophe reinsurers and
reinsurance departments of numerous multi-line insurance organizations.
Tempest competes effectively because of its strong capital position, the
quality of service provided to customers, the leading role Tempest plays in
setting the terms, pricing and conditions in negotiating contracts, its
customised approach to risk selection and the sponsorship and support of its
parent, ACE.
 
  Tempest has also received an A (Excellent) rating from A.M. Best.
 
 Lloyd's of London Operations
 
  Lloyd's of London ("Lloyd's") is a long established insurance marketplace
where many varied forms of insurance are sold by syndicates, which are annual
joint ventures of participating capital providers known as "Names".
Participation as a Name on a syndicate carries with it unlimited liability for
the Name's share of any insurance losses incurred by the syndicate (each Name
participated severally). In 1994, the rules surrounding participation were
changed to allow limited liability "corporate names" to enter the Lloyd's
marketplace as capital providers.
 
  Several of the underwriting years of the late 1980's and early 1990's proved
to be particularly unprofitable for many of the syndicates operating at
Lloyd's. This proved to be financially disastrous for some of the Names on the
affected syndicates due to the unlimited liability of their participation.
During the last three years, Lloyd's governing body has been seeking to
implement a reconstruction and renewal plan to allow the market to continue.
In August 1996 this plan was formally approved by the required parties and a
new company, Equitas, was authorized to underwrite the liabilities of the 1992
and prior years of account of all syndicates at Lloyd's. The funding for this
solution came from a variety of sources including the premiums on the
liabilities assumed by Equitas as well as a series of levies charged to
entities that had historically provided services to the Lloyd's insurance
market (including managing agencies and insurance brokers).
 
  Participation in selective syndicates in the Lloyd's insurance market
provides the Company with new lines of business in the aviation, marine and
non-marine markets as well as the opportunity to diversify its insurance risk
profile through markets to which it would otherwise not have access. This
syndicate participation is through a dedicated corporate capital vehicle thus
limiting the liability of the Company.
 
  In order to more closely monitor its syndicate participation the Company has
acquired Methuen, the holding company for MUL, and Ockham Worldwide, the
holding company for two other managing agencies, ALVL and ALUL. These three
agencies provide accounting, reporting and ancillary insurance services to the
syndicates in which the Company participates or will participate for the 1997
year of account.
 
                                       9
<PAGE>
 
  For the 1996 year of account the Company has committed (Pounds)12.25 million
(approximately $18 million) of capital spread amongst the six syndicates
managed by MUL, which will support up to (Pounds)24.5 million (approximately
$37 million) of premium writing capacity. For the 1997 year of account the
Company has agreed to provide funds at Lloyd's of approximately (Pounds)62
million (approximately $93 million) to support up to approximately (Pounds)124
million (approximately $186 million) of underwriting capacity on syndicates
managed by MUL.
 
  On November 26, 1996, the Company acquired Ockham Worldwide Holdings PLC
("Ockham Worldwide"), a wholly owned subsidiary of Ockham Holdings PLC
("Ockham"). Ockham Worldwide owns two Lloyd's managing agencies, ACE London
Aviation Limited ("ALVL") (formerly Ockham Sturge Aviation Agency Ltd.) and
ACE London Underwriting Limited ("ALUL") (formerly Ockham Worldwide Agency
Ltd.). Together these two agencies manage seven syndicates with total
underwriting capacity for the 1996 year of account of (Pounds)349 million
(approximately $524 million). Ockham Worldwide also owns a Lloyd's corporate
member which provides funds at Lloyd's to support underwriting on these
syndicates. The Company expects to provide approximately (Pounds)15 million
(approximately $23 million) of underwriting capacity to the syndicates managed
by Ockham Worldwide for the 1997 year of account.
 
  The syndicates managed by MUL, ALVL and ALUL underwrite an extensive range
of insurance and reinsurance risks worldwide. Risks underwritten include most
classes of aviation and space, property and liability, marine and energy
business. All business is underwritten through registered Lloyd's insurance
brokers either on a direct basis or as facultative or treaty reinsurance.
 
  There is significant competition in all classes of business transacted by
the syndicates and emanates from a number of different markets worldwide.
Depending on the class of business concerned competition comes from the London
market; other Lloyd's syndicates and ILU Companies (Institute of London
Underwriters), major international insurers and reinsurers. On international
risks, competition also comes from the domestic insurers in the country of
origin of the insured.
 
  The syndicates are able to compete successfully by developing and
maintaining close, long term relationships with clients through a high quality
service and an ability to deliver innovative solutions tailored to the
client's needs.
 
 Claims Administration
 
  Claims arising under policies issued by ACE Insurance and CODA are managed
in Bermuda by the Company's claims department. The Company maintains a claims
database into which all notices of loss are entered. If the claims department
determines that a loss is of sufficient severity, it makes a further inquiry
of the facts surrounding the loss and, if deemed required, retains outside
claims counsel to monitor claims. Based upon its evaluation of the claims
file, the Company's claims department may recommend that a case reserve in a
specified amount be established or that all or part of a claim be paid. The
Company's claims department monitors all claims files and, where appropriate,
will recommend the establishment of a new case reserve or the increase or
decrease of an existing case reserve with respect to a claim.
 
  With the exception of certain aviation coverages, the Company does not
undertake to defend its insureds. It has, in certain instances, provided
advice to insureds with respect to the management of claims. The Company
believes that its experience in resolving large claims and its proactive
approach to claims management has contributed to the favourable resolution of
several cases.
 
  Because the Company does not do business in the U.S., it must often rely on
U.S. counsel to assist it in evaluating liability and damages confronting its
insureds in the U.S. The Company does not believe that the information
received or the procedures followed have materially or adversely affected its
ability to identify, review or settle claims.
 
 
                                      10
<PAGE>
 
  Claims arising under contracts written by Tempest are managed in Bermuda by
Tempest. Tempest also maintains a claims database into which all notices of
loss are entered. Loss notices are received from brokers. They are reviewed and
case reserves are established for Tempest's portion of the loss in excess of
the contract's attachment point. Case reserves are then adjusted based on
receipt of further notifications from brokers.
 
  With respect to claims arising in Lloyd's syndicates, each syndicate
maintains a claims database into which all notices of loss are entered. These
are primarily notified by various central market bureaux, such as, through a
daily electronic data interchange message. Where a syndicate is a "leading"
syndicate on a Lloyd's policy, then it acts through its underwriters and claims
adjusters, on behalf of itself and the following market, in dealing with the
broker and/or insured for any particular claim. This may involve the
appointment of attorneys and/or loss adjusters. The leading syndicates,
together with the claims bureaux, advise movements in case reserves to all
syndicates participating on the risk.
 
  All information received with respect to case reserves, whether on "lead
business" or on "following business", are screened, validated and recorded by
the syndicates. The syndicates' claims departments can vary the case reserves
carried from those advised by the bureaux and can carry reserves for claims not
processed by the bureaux. Any such adjustments and entries are specifically
identifiable within the claims system.
 
 Unpaid Losses and Loss Expenses
 
  The Company is required to make provisions in its financial statements for
the estimated unpaid liability for losses and loss expenses for claims made
against it under the terms of its policies and agreements. Estimating the
ultimate liability for losses and loss expenses is an imprecise science subject
to variables that are influenced by both internal and external factors. This is
true because claim settlements to be made in the future may be impacted by
changing rates of inflation and other economic conditions, changing
legislative, judicial and social environments and changes in the Company's
claims handling procedures. In many cases, significant periods of time, ranging
up to several years or more, may elapse between the occurrence of an insured
loss, the reporting of the loss to the Company and the settlement of the
Company's liability for that loss. In other cases, the period between first
notice and final payment can be relatively short, even less than one year.
 
  Several aspects of the Company's operations exacerbate the inherent
uncertainties in estimating its losses as compared to more conventional
insurance companies. Primary among these aspects are the limited amount of
statistically significant historical data regarding losses, particularly of the
type intended to be covered by the Company's excess liability policies and the
expectation that losses in excess of the attachment level of the policies will
be characterized by low frequency and high severity, limiting the utility of
claims experience of other insurers for similar claims. Accordingly, the
ultimate claims experience of the Company cannot be as reliably predicted as
may be the case with more traditional insurance companies, and there can be no
assurance that losses and loss expenses will not exceed the reserves.
 
  A number of the Company's insureds have given notice of claims relating to
breast implants or components or raw material thereof that had been produced
and/or sold by such insureds. Lawsuits, including class actions, involving
thousands of implant recipients have been filed in both state and federal
courts throughout the United States. Most of the federal cases have been
consolidated pursuant to the rules for Multidistrict Litigation to a Federal
District Court in Alabama. At June 30, 1994, the Company increased its then
existing reserves relating to breast implant claims. Although the reserve
increase was partially satisfied by an allocation from existing IBNR, it also
required an increase in the Company's total reserve for unpaid losses and loss
expenses at June 30, 1994 of $200 million. The increase in reserves was based
on information made available in conjunction with the Global I settlement
(including information relating to opt-outs) and information made available
from the Company's insureds and was predicated upon an allocation between
coverage provided before and after the end of 1985 (when the Company commenced
underwriting operations). No additional reserves relating to breast implant
claims have been added since June 30, 1994. The Company continually evaluates
its reserves in light of developing information and in light of discussions and
negotiations with its insureds. In August 1996, the Company settled with one of
its insureds, a breast implant manufacturer, for a sum of money to be paid out
over
 
                                       11
<PAGE>
 
a number of years in the future. The settlement is consistent with the
Company's belief that its reserves are adequate. Significant uncertainties
continue to exist with regard to the ultimate outcome and cost of Settlement II
and the number and value of the opt-out claims. The Company is unable at this
time to determine whether additional reserves, which could have a material
adverse effect upon the financial condition, results of operations and cash
flows of the Company, may be necessary in the future. See "Management's
Discussion and Analysis of Results of Operations and Financial Condition--
Breast Implant Litigation" in the 1996 Annual Report to shareholders filed with
this Form 10-K.
 
  After a claim is reported to the Company, a case reserve is established for
the estimated ultimate losses and loss expenses, if any, with respect to the
reported claim. The amount and timing of the reserve reflects the judgment of
the claims personnel, based upon general corporate reserving practices and on
the experience and knowledge of the claims personnel (including, where
appropriate, outside counsel and claim consultants) regarding the nature and
value of the specific type of claim.
 
  The process in estimating ultimate liability employed by the Company is set
forth in an actuarial report (the "Actuarial Report") prepared annually by the
Company's Chief Actuary. The Company engages an independent actuarial firm to
review the Actuarial Report on an annual basis. As stated in its actuarial
review, such firm believed that the methods and assumptions contained in the
Actuarial Report were reasonable and appropriate for use in setting loss
reserves at September 30, 1996. Such Actuarial Report contains a number of
qualifications with respect to the complications and relative uncertainty that
exists in establishing reserves for the Company's lines of business, which
qualifications are substantially similar to those discussed above.
 
  Losses and loss expenses are charged to income as incurred. The reserve for
unpaid losses and loss expenses represents the estimated ultimate losses and
loss expenses less paid losses and loss expenses and is composed of case
reserves, loss expense reserves and IBNR loss reserves. During the loss
settlement period, which can be many years in duration, additional facts
regarding individual claims and trends often will become known. As these become
apparent, case reserves may be adjusted by allocation from the IBNR loss
reserve without any change in the overall reserve. In addition, application of
the statistical and actuarial method may require the adjustment of the overall
reserves upward or downward from time to time. The final liability nonetheless
may be significantly greater than or less than the prior estimates.
 
  At September 30, 1996, the reserve for unpaid losses including IBNR loss
reserves was $1,806.3 million and the reserve for loss expenses was $29.8
million. The Company believes that its reserves for unpaid losses and loss
expenses including those arising from breast implant claims are adequate as of
September 30, 1996.
 
  The "Analysis of Loss and Loss Expense Development" shown below presents the
subsequent development of the estimated year-end liability for unpaid losses
and loss expenses since the Company's inception at the end of each of the years
in the eleven-year period ended September 30, 1996. The top line of the table
shows the estimated liability for unpaid losses and loss expenses recorded at
the balance sheet date for each of the indicated years. This liability
represents the estimated amount of losses and loss expenses for claims arising
from all prior years' policies and agreements that were unpaid at the balance
sheet date, including IBNR loss reserves. The upper (paid) portion of the table
presents the amounts paid as of subsequent years on those claims for which
reserves were carried as of each specified year. The lower portion of the table
shows the re-estimated amount of the previously recorded liability as of the
end of each succeeding year. Several aspects of the Company's operations,
including the low frequency and high severity of losses in the high excess
layers in which the Company provides insurance, complicate the actuarial
reserving techniques utilized by the Company. Accordingly, the Company expects
that ultimate losses and loss expenses attributable to any single underwriting
year will be either more or less than the incremental changes in the lower
portion of the following table. Management believes, however, that the losses
and loss expenses which have been recorded through September 30, 1996,
including those arising from breast implant claims, are adequate to cover the
ultimate cost of losses and loss expenses incurred through September 30, 1996
under the terms of the Company's policies and agreements. Since such provisions
are necessarily based on estimates, the ultimate losses and loss expenses may
be significantly greater or less than such amounts. See "Management's

  The Company does not consider it appropriate to extrapolate future
deficiencies or redundancies based upon the above tables, as conditions and
trends that have affected development of liability in the past may not
necessarily occur in the future.
 
  In 1994, the Company recorded an additional reserve of $200 million, related
primarily to developments in breast implant litigation, in respect of years
prior to 1994.
 
  In 1992, the Company began applying actuarial and statistical methods to
estimate ultimate expected losses and loss expenses for all of the Company's
business since inception. As at September 30, 1994 the Company changed its
method of allocating IBNR to accident and balance sheet years. This allocation
assigns IBNR to years based upon various risk factors including immaturity of
year, amount of earned premium in that year, and development of known claims.
As the Company's loss experience is characterized as low frequency, and high
severity, IBNR is considered a bulk reserve, and is therefore available for
loss development from which ever year it may arise. Prior to 1994, the
allocation of IBNR to accident and balance sheet years was based upon a loss
distribution indicated by the expected loss method employed by the Company.
Losses paid for the year ending September 30, 1988 include an amount of $23.4
million, which is expected to be recovered from an insured.
 
  The table has been re-stated to include CODA's and Tempest's loss experience
as if both companies had been wholly owned subsidiaries of the Company from
their inception.

  The "cumulative redundancy/(deficiency)" shown in the table represents the
aggregate change in the reserve estimates over all subsequent years. The
amounts noted are cumulative in nature; that is, an increase in loss estimate
for prior year losses generates a deficiency in each intermediate year. For
instance, a deficiency recognized in 1994 relating to losses incurred during
the year ending September 30, 1992 would be included in the cumulative
deficiency amount for each year from September 30, 1992 to the year the loss
was recognized (1994), yet the deficiency would be reflective in operating
results only in 1994. An analysis of the changes in aggregate reserves for
losses and loss expenses under GAAP is presented below. Since reserves are
necessarily based upon estimates, the ultimate net costs may vary from the
original estimates. As adjustments to these estimates become necessary, they
are reflected in current operations.

 Investments
 
  The Finance Committee of the Board of Directors is responsible for the
establishment of the Company's investment policy consistent with the Company's
strategies, goals and objectives. The investment policy is reviewed with, and
approved by, the Board of Directors.
 
  The Company's primary investment objectives are to ensure that funds will be
available to meet its insurance and reinsurance obligations and then, to
maximize its rate of return on invested funds within specifically approved
constraints as to credit quality, liquidity and volatility. Accordingly, the
Company's investment portfolio is invested primarily in fixed income
instruments of high credit quality.
 
  The Company has divided the consolidated investment portfolio into three
segments. Assets which are required to match and offset certain specifically
identified liabilities are segregated in an asset-liability management ("ALM")
segment. The second segment, the core portfolio, supports the current general
insurance exposures and is structured to have low to moderate investment risk.
The remainder of the portfolio, the discretionary segment, is invested to
enhance total return and return on equity by taking on additional investment
risks within prudent limits. The core and discretionary portfolios are managed
by professional outside managers whose performance is measured against certain
recognized broad market indices. Written investment guidelines, approved by the
Finance Committee, document standards to ensure portfolio liquidity and
diversification,
 
                                       14
<PAGE>
 
maintain credit quality, and limit volatility within approved asset allocation
guidelines. The use of financial futures and options contracts, as well as
certain mortgage derivative securities which do not provide a planned stable
structure of principal and interest payments, require prior approval from the
Finance Committee.
 
  Funds are invested in both U.S. and non-U.S. dollar denominated high-quality
fixed maturity and equity securities. The asset strategy allocates 20 percent
of the consolidated investment portfolio to have an exposure to equities, with
international equities limited to no more than 35 percent of total equities.
This represents an increase from the period January 1995 to May 1996, when the
equity allocation was 15 percent, with international equities limited to no
more than 20 percent of total equities. The remainder of the consolidated
portfolio is to be invested in fixed income securities, with international
bonds limited to 5 percent of the total portfolio. Currency hedging is
permitted and used at the discretion of the investment managers. Prior to the
first quarter of fiscal 1995, all investments were denominated in U.S. dollars,
and total equity exposure was limited to 10 percent of the consolidated
investment portfolio.
 
  The fixed maturity portion of the Company's investment portfolio includes
U.S. and non-U.S. government obligations, corporate bonds, mortgage-backed
securities, and other investment grade securities. The Company's investment
guidelines do not permit investments in non-investment grade securities and
limit the total "BBB" exposure of the portfolio. To ensure diversity and limit
concentrations of credit risk, no more than 5 percent of the portfolio may be
invested in the obligations of any one issuer (other than the U.S. government).
 
  The Company includes its investment in Centre Reinsurance Holdings Limited, a
privately held Bermuda-domiciled reinsurer specializing in finite risk
reinsurance, as "other investments" in the consolidated financial statements.
This investment was originally made as part of a strategic business decision
and is not governed by the objectives and investment guidelines established for
the consolidated investment portfolio.
 
  Applicable insurance laws and regulations do not restrict the Company's
investments except that certain types of investments (such as unquoted equity
securities, investments in affiliates, real estate and collateral loans) may
not qualify as a "relevant asset" for purposes of satisfying Bermuda statutory
requirements. See "Regulation--Bermuda."
 
  For additional information regarding the investment portfolio, including
breakdowns of the sector and maturity distributions, see note 4 to the
consolidated financial statements included in the 1996 Annual Report to
Shareholders.
 
 Regulation
 
  Bermuda
 
  The businesses of ACE Insurance, CODA and Tempest are regulated by the
Insurance Act 1978 (as amended by the Insurance Amendment Act 1995) and related
regulations (the "Act"). The Act imposes on Bermuda insurance companies
solvency and liquidity standards and auditing and reporting requirements and
grants the Minister of Finance (the "Minister") powers to supervise,
investigate and intervene in the affairs of insurance companies. The Act
provides for four classes of insurance company. ACE Insurance and Tempest have
been designated as Class 4 insurers, which is the designation for the largest
companies requiring capital and surplus in excess of $100 million. CODA has
been designated a Class 3 insurer requiring capital and surplus in excess of
$1million. Each registered insurer must appoint an independent auditor to audit
and report on the Statutory Financial Statements and Statutory Financial Return
on an annual basis. The independent auditor must be approved by the Minister.
Each Class 3 and Class 4 insurer must appoint a loss reserve specialist, who
must also be approved by the Minister, to review and report on the loss
reserves of the insurer on an annual basis. Class 3 and Class 4 companies are
required to file their Statutory Financial Return and Statutory Financial
Statements with the Registrar of Companies in Bermuda (the "Registrar"), who is
the chief administrative officer under the Act, no later than four months from
the insurer's fiscal year end. The Statutory Financial Return includes, among
other matters, the report of the approved independent auditor; the actuarial
opinion on loss
 
                                       15
<PAGE>
 
reserves prepared by the approved loss reserve specialist; a declaration of
statutory ratios; and a solvency certificate. Both the declaration of
statutory ratios and the solvency certificate must be signed by at least two
directors of the insurer.
 
  United Kingdom
 
  London Representative Office
 
  The Company has established for marketing purposes, representative offices
in London, England. However, all underwriting operations continue to be
conducted in Bermuda.
 
  Lloyd's
 
  The Company and its relevant UK subsidiaries are subject to the regulatory
jurisdiction of the Council of Lloyd's (the "Council") as a result of the
acquisition by the Company of a majority interest in Methuen and the
establishment of ACE Capital Limited ("ACE Capital"), a UK limited liability
corporate member of Lloyd's formed in connection with the Methuen acquisition.
In addition, as part of the acquisition of Ockham Worldwide, the Company
acquired a separate UK limited liability corporate member of Lloyd's, ACE
London Ltd ("ACE London"), which is subject to the same regulations as ACE
Capital. Unlike other financial markets in the UK, Lloyd's is not subject to
direct UK government regulation through the UK Financial Services Act 1986
but, instead, is self regulating by virtue of the Lloyd's Act 1982 through
bye-laws, regulations and codes of conduct made by the Council, which governs
the market. Under the Council there are two Boards, the Market Board and the
Regulatory Board. The former is led by working members of the Council and is
responsible for strategy and the provision of services such as premium and
claims handling, accounting and policy signing. The Regulatory Board is
responsible for the regulation of the market, compliance and the protection of
policyholders. Under the regulations, the approval of Council has to be
obtained before any person can be a "major shareholder" or "controller" of a
corporate member or a managing agency. The Company has been approved as a
"controller".
 
  A person would be viewed by Lloyd's as a "major shareholder" of ACE Capital
or ACE London if such person owns 15 percent or more of the Company's
outstanding capital stock and as a "controller" if it owns 30 percent or more
of the Company's outstanding capital stock. Therefore, any person that becomes
the owner of 15 percent or more of the Company's stock may be required to
deliver a declaration and undertaking to Lloyd's, in the form prescribed by
Lloyd's, unless Lloyd's exempts such person from this requirement. Lloyd's
current practice is to require from a corporate member notification of
information concerning any person that becomes a "major shareholder" but only
to require such a declaration and undertaking to be given if the shareholders'
interest exceeds 20 percent. Lloyd's has stated that this undertaking does not
make such person liable for the Lloyd's business of ACE Capital or ACE London.
The Company is seeking an exemption from this requirement from Lloyd's for
certain categories of investors, but there is no assurance that such an
exemption will be obtained.
 
  As a "controller", the Company is required to give certain undertakings,
directed principally towards ensuring that there is no direct interference in
the conduct of the business of the managing agency, but there are no
provisions in the Lloyd's Act 1982, the bye-laws or the regulations which
provide for any liabilities of ACE Capital or Methuen to be met by the
Company. In addition, a managing agency is required to comply with various
capital and solvency requirements, and to submit to regular monitoring and
compliance procedures. ACE Capital and ACE London, as corporate members of
Lloyd's, are each required to commit an amount broadly equal to 50 percent of
their underwriting capacity on the syndicates to support its underwriting on
those syndicates.
 
  Under English law, if any person that holds or subsequently becomes the
holder of more than 5 percent of the Company's stock also owns any interest in
a Lloyd's broker or is a partner or a director of a Lloyd's broker, that
Lloyd's broker risks losing its Lloyd's license. For these purposes "Lloyd's
broker" includes the holding company of a corporate Lloyd's broker, any
company which controls (a test based on one-third voting rights or
 
                                      16

control of the board) such a Lloyd's broker or its holding company or if the
Lloyd's broker is a partnership any person who controls (on a similar test)
such a Lloyd's broker or one of its partners.
 
  United States of America
 
  The Company and its insurance subsidiaries, excluding its Lloyd's
operations, are not admitted to do business as insurers in any jurisdiction in
the U.S. Each state in the U.S. licenses insurers and prohibits, with some
exceptions, the sale of insurance products by non-admitted insurers within
their applicable jurisdictions.
 
  The Company conducts its business from its offices in Bermuda. All of the
Company's insurance clients are obtained through non-U.S. insurance brokers
and non-U.S. affiliates of U.S. insurance brokers. All policies are issued and
delivered and premiums are received in Bermuda. Based on, among other things,
the foregoing, the Company does not believe it is in violation of the
insurance laws of any state in the U.S.
 
  Many states impose a premium tax (typically 2 percent to 4 percent of gross
premiums) on insureds obtaining insurance from nonadmitted foreign insurers,
such as ACE Insurance and CODA. The premiums charged by the Company do not
include any American state premium tax. Each insured is responsible for
determining whether it is subject to any such tax and for paying such tax as
may be due.
 
  The U.S. also imposes on policyholders an excise tax on insurance and
reinsurance premiums paid to foreign insurers or reinsurers with respect to
risks located in the United States. The rates of tax applicable to premiums
paid to ACE Insurance and CODA are 4 percent or insurance premiums and 1
percent for reinsurance premiums.
 
  The Company has from time to time received inquiries from certain U.S. state
insurance regulators regarding the Company's activities in a particular
jurisdiction. To date only the State of Nevada Department of Insurance has
formally challenged the insurance activities of the Company and that challenge
was resolved in favor of the Company by legislation. There can be no assurance
that additional challenges will not be raised in the future or that the
Company will be able to successfully defend against such challenges. Such
challenges may arise, among other things, in connection with actions seeking
the payment of state premium taxes from insureds.
 
  In the event that the Company is not able to successfully defend against
challenges by certain U.S. jurisdictions, the Company's business could be
adversely affected in the short term. However, should this occur, the Company
could elect to qualify as a surplus lines insurer in such U.S. jurisdictions
as were necessary. Were it necessary to do so, the Company believes that
generally it could meet and comply with the prescribed legislative
requirements, and such compliance would not have a material impact on the
ability of the Company to conduct its business or its results of operations.
 
  If the Company is unable to defend successfully against challenges of U.S.
jurisdiction, it is possible that a policyholder could attempt to sue the
Company in a U.S. court. Although the Company's policies have a mandatory
arbitration clause for coverage disputes, courts in some states can impose
damages in excess of policy limits if an insurer is found to have improperly
and in bad faith declined coverage. If a U.S. court took jurisdiction of such
a claim, it is possible that the Company's exposure could be significantly
greater than policy limits.
 
  There can be no assurance that new or additional legislation will not be
proposed and enacted that has the effect of subjecting the Company to
regulation in the U.S.

 Tax Matters
 
  United States of America
 
  Corporate Income Tax
 
  ACE is a Cayman Islands corporation and has never paid U.S. corporate income
taxes (other than withholding taxes on dividend income) on the basis that it
is not engaged in a trade or business in the U.S.; however, there can be no
assurance that the Internal Revenue Service ("IRS") will not contend to the
contrary. If the Company were subject to U.S. income tax, there could be a
material adverse effect on the Company's shareholders' equity and earnings.
The Company and its subsidiaries do not file U.S. income tax returns reporting
income subject to U.S. income tax since they do not conduct business within
the U.S. except that the Company and its insurance subsidiaries have filed
protective tax returns reporting no U.S. income to preserve their ability to
deduct their ordinary and necessary business expenses should the IRS
successfully challenge the Company's contention that none of its income is
subject to a net income tax in the U.S.
 
  Related Person Insurance Income
 
  Each U.S. person who beneficially owns Ordinary Shares of the Company
(directly or through foreign entities) on the last day of an insurance company
subsidiary's fiscal year will have to include in such person's gross income
for U.S. tax purposes a proportionate share (determined as described herein)
of the related person insurance income ("RPII") of such insurance company
subsidiary if the RPII of such insurance company subsidiary, determined on a
gross basis, is 20 percent or more of that insurance company subsidiary's
gross insurance income in such fiscal year. RPII is income attributable to
insurance policies where the direct or indirect insureds are U.S. shareholders
or are related to U.S. shareholders of the Company. RPII may be includible in
a U.S. shareholder's gross income for U.S. tax purposes regardless of whether
or not such shareholder is an insured. For the fiscal year ended September 30,
1996, the Company believes that gross RPII of each of its insurance company
subsidiaries was below 20 percent for the year. Although no assurances can be
given, the Company anticipates that gross RPII of each of its insurance
company subsidiaries will be less than 20 percent of each such subsidiary's
gross insurance income for subsequent years and the Company will endeavor to
take such steps as it determines to be reasonable to cause its gross RPII to
remain below such level.
 
  The RPII provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), have never been interpreted by the courts. Regulations interpreting
the RPII provisions of the Code exist only in proposed form, having been
proposed on April 16, 1991. It is not certain whether these regulations will
be adopted in their proposed form or what changes or clarifications might
ultimately be made thereto or whether any such changes, as well as any
interpretation or application of RPII by the IRS, the courts, or otherwise,
might have retroactive effect. For a more detailed discussion of RPII and
other tax matters pertaining to an investment in the Company's shares,
reference is hereby made to the section entitled "Taxation of Ace and its
Shareholders" in the Company's Registration Statement on Form S-4 (No. 333-
04153), which section is incorporated by reference herein.
 
  United Kingdom
 
  Lloyd's is required to pay U.S. income tax on U.S. connected income ("U.S.
income") written by Lloyd's syndicates. Lloyd's has a closing agreement with
the IRS whereby the amount of tax due on this business is calculated by
Lloyd's and remitted directly to the IRS. These amounts are then charged to
the personal accounts of the Names in proportion to their participation in the
relevant syndicates. ACE Capital is subject to this arrangement but, as a UK
domiciled company, will receive UK corporation tax credits for any U.S. income
tax incurred up to the value of the equivalent UK corporation income tax
charge on the U.S. income.
 
  Methuen and Ockham Worldwide are subject to UK corporation tax and value
added tax. The Company's corporate subsidiary which has acquired Methuen and
Ockham Worldwide and ACE Capital and ACE London Ltd., the Lloyd's corporate
members participating in the managed by MUL, ALVL and ALUL syndicates are also
subject to UK corporation tax and value added tax.

  Although the Company has representative offices in London, it has been
advised that it is not deemed to be doing insurance business in the UK and
therefore is subject only to minimal tax in the UK.
 
  With effect from October 1, 1994, the UK imposed an insurance premium tax on
that portion of policies related to certain UK risks. ACE has registered to
collect and pay this tax on behalf of UK domiciled policyholders.
 
  Bermuda
 
  Under current Bermuda law, the Company is not required to pay any taxes on
its income or capital gains. The Company has received an undertaking from the
Minister of Finance that, in the event of any taxes being imposed, the Company
will be exempt from taxation in Bermuda until March 2016.
 
 Employees
 
  At September 30, 1996, the Company employed a total of 256 persons, 118 of
whom were located in Bermuda and 138 in London. Of the 118 persons employed in
Bermuda, 14 are employed by Tempest. Of the 138 persons employed in London, 134
are employed by Methuen. None of these employees is represented by a labor
union.

Stand alone basis......................  A term referring to an insurance pol-
                                         icy which is governed by its own
                                         terms, conditions, exclusions and re-

                                         mium paid to it, agrees to indemnify

                                         risks. A risk in this context might
                                         mean the insurance coverage on one
                                         building or a group of buildings.

                                         and the reinsurer is obligated to ac-

ITEM 2. PROPERTIES
 
  The Company leases office space in Hamilton, Bermuda for its principal
offices. The lessor is a joint venture in which the Company has a 40 percent
interest and there is an agreement with the joint venture partner which
ensures the Company's ability to occupy a portion of the building until 2011.
Tempest also leases office space in Hamilton, Bermuda for its principle
offices under a non-cancelable lease expiring in 1998 with a three year
renewal option. Methuen leases office space at 122 Leadenhall Street, London,
England for its principal offices. The lease expires in June 2012. Methuen
also leases an office in the 1986 Lloyd's Building in London. The lease has
termination dates of September 2001 and 2006.
 
ITEM 3. LEGAL PROCEEDINGS
 
  The Company, in common with the insurance industry in general, is subject to
litigation in the normal course of its business. Although all of the Company's
policies provide for resolution of disputes by arbitration in Bermuda or
London, the Company has been sued by insureds several times in the United
States and, with one exception which is currently on appeal, has been
successful in either being dismissed from such suits or in having such suits
dismissed on procedural grounds or stayed pending the results of arbitration.
In addition, the Company is occasionally named as a party in Louisiana "direct
action" suits by insureds. The Company has sought dismissal of these actions
as well and decisions are pending in these actions. At September 30, 1996, the
Company was not a party to any material litigation other than as encountered
in claims activity and none of such litigation is expected by management to
have a materially adverse effect on the Company's financial condition.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  Other then the Extraordinary General Meeting held on July 1, 1996 which was
reported in the Company's June 30, 1996 Form 10-Q, no matters were submitted
to a vote of stockholders during the fourth quarter of the fiscal year covered
by this report.

                                   SECTION 1
                                   ---------


                                    GENERAL
                                    -------


     Purpose.  The ACE Limited 1996 Replacement Option Plan (the "Plan") has
been established by ACE Limited (the "Company") to award Replacement Options in
satisfaction of its obligation under Section 5.11 of the Agreement and Plan of
Amalgamation, dated as of March 14, 1996, as amended (the "Amalgamation
Agreement") by and among the Company, TRCL Acquisition Limited, and Tempest
Reinsurance Company Limited ("Tempest").


     Participation.  Subject to the terms and conditions of the Plan,
participation in the Plan shall be limited to those persons entitled to
Replacement Options pursuant to the Amalgamation Agreement.


     Operation and Administration.  The operation and administration of the
Plan, including the Replacement Options granted under the Plan, shall be subject
to the provisions of Section 3. Capitalized terms in the Plan shall be defined
as set forth in Section 7 or elsewhere in the Plan.


                                    SECTION
                                    -------


                                    OPTIONS
                                    -------


     Definition.  The grant of a Replacement Option under this Section 2
entitles the Participant to purchase shares of Stock at a price fixed at the
time the Replacement Option is granted, as determined in accordance with the
Amalgamation Agreement, subject to the terms of this Section 2. Options granted
under this Section 2 shall be Non-Qualified Options. A "Non-Qualified Option" is
an option that is not intended to be an "incentive stock option" as that term is
described in section 422(b) of the Code.


     Eligibility.  Replacement Options shall be awarded by the Committee under
this Section 2 to the extent required by the terms of the Amalgamation
Agreement. Individuals to whom Replacement Options are granted shall thereby
become "Participants" in the Plan, and the Committee shall determine the number
of shares of Stock to be subject to each such Replacement Option, all in
accordance with the terms of the Amalgamation Agreement.


     Price.  The determination and payment of the purchase price of a share of
Stock under each Replacement Option granted under this Section 2 shall be
subject to the following:


     The purchase price shall be established by the Committee in accordance with
     the Amalgamation Agreement.


     Subject to the following provisions of this subsection 2.3, the full
     purchase price of each share of Stock purchased upon the exercise of any
     Replacement Option shall be paid at the time of such exercise and, as soon
     as practicable thereafter, a certificate representing the shares so
     purchased shall be delivered to the person entitled thereto.


     The purchase price shall be payable in cash or in shares of Stock (valued
     at Fair Market Value as of the day of exercise), or in any combination
     thereof, as determined by the Committee.


     A Participant may elect to pay the purchase price upon the exercise of an
     Replacement Option through a cashless exercise arrangement as may be
     established by the Committee.
<PAGE>
 
     Exercise.  Except as otherwise expressly provided in the Plan, a
Replacement Option granted under this Section 2 shall be exercisable in
accordance with the following terms of this subsection 2.4:


     The terms and conditions relating to exercise of a Replacement Option shall
     be established by the Committee, subject to the terms of the Amalgamation
     Agreement.

     Each Replacement Option granted under the Plan shall be exercisable at the
     time fixed by the Committee when the Replacement Option is granted,
     provided that the time so fixed shall be in accordance with the
     requirements of the Plan and the Amalgamation Agreement.

     Any portion of the Replacement Option that is exercisable may be exercised
     in whole or in part by filing a written notice with the Secretary of the
     Company at its corporate headquarters, provided that the notice is filed
     prior to the date the Replacement Option expires.  Such notice shall
     specify the number of shares of Stock which the Participant elects to
     purchase, and shall be accompanied by payment of the purchase price for
     such shares of Stock indicated by the Participant's election.  Subject to
     the provisions of subsection 2.3, payment shall be by cash or by check
     payable to the Company, or by shares of Stock (valued at Fair Market Value
     as of the day of exercise), or in any combination thereof.

     Expiration Date.  The "Expiration Date" with respect to a Replacement
Option means the date established as the Expiration Date by the Committee at the
time of the grant of the Replacement Options all in accordance with the terms of
the Amalgamation Agreement; provided that Replacement Options will not be
exercisable after the expiration of ten (10) years from the date of grant of the
option which the Replacement Option is replacing in accordance with the terms of
the Amalgamation Agreement.

     Termination of Employment.  Unless otherwise set forth in the agreement
evidencing the grant of the Replacement Option, in the event that a Date of
Termination occurs with respect to a Participant, any outstanding Replacement
Options held by such Participant shall terminate as follows:


     If the Participant's Date of Termination occurs by reason of his death,
     Disability or Retirement, the Replacement Option (to the extent exercisable
     at the time of the Participant's Date of Termination) shall be exercisable
     for a period of one (1) year following such Date of Termination, and shall
     thereafter terminate.


     If the Participant's Date of Termination occurs for Cause, the Replacement
     Option shall terminate on the date of the Participant's Date of
     Termination.


     If the Participant's Date of Termination occurs for any other reason, the
     Replacement Option (to the extent exercisable at the time of the
     Participant's Date of Termination) shall be exercisable for a period of
     ninety (90) days following such Date of Termination, and shall thereafter
     terminate.


     Notwithstanding the foregoing, the Board may, in its discretion, provide
that the Replacement Option may be exercised after the periods provided for in
this Section 2, but in no event beyond the term of the Replacement Option.


     Termination as Non-Employee Director.  Subject to the terms of this
subsection 2.7, each Replacement Option granted to a Non-Employee Director shall
be for a term of ten (10) years from the date of grant of the option which the
Replacement Option
<PAGE>
 
is replacing in accordance with the terms of the Amalgamation Agreement. Upon
the cessation of a Non-Employee Director's membership on the Board of Directors
of the Company or any Related Company for any reason other than for Cause,
Replacement Options granted to such Non-Employee Director shall expire upon the
earlier of (i) three (3) years from the date of such cessation of Board
membership or (ii) expiration of the term of the Replacement Option. The Board
may not provide for an extended exercise period beyond the periods set forth in
this subsection 2.7. Replacement Options granted to a Non-Employee Director
whose membership on the Board of Directors of the Company or any Related Company
is terminated for Cause shall expire on the date of such termination.

     Pre-Effective Date Terminations.  If an individual's employment with
Tempest and any Subsidiary, as determined under the terms of the Tempest
Reinsurance Company 1994 Stock Option Plan ("Tempest Plan") terminates prior to
the Effective Date, or, if an individual who was a non-employee director under
the Tempest Plan ceases membership on the Board of Directors of Tempest prior to
the Effective Date, and immediately prior to the Effective Date, the individual
held an unexercised option of the type which the Replacement Option is replacing
in accordance with the terms of the Amalgamation Agreement, than such
unexercised option shall be replaced in accordance with Section 2 of the Plan,
subject to the terms of the Plan, and treating the dates on which the individual
terminated employment with Tempest and its Subsidiaries as the individual's Date
of Termination under this Plan (or with respect to a non-employee director,
treating the date of his cessation of membership on the Board of Directors of
Tempest as a cessation of membership on the Board under this Plan); provided,
however, that nothing in this Plan shall be construed to (i) extend the time
during which such option is exercisable to a date that is later than the date on
which it would cease to be exercisable in the absence of the transaction
contemplated by the Amalgamation Agreement, or (ii) permit the exercise of any
portion of such option that would not be exercisable in the absence of the
transaction contemplated by the Amalgamation Agreement.


                                    SECTION
                                    -------


                          OPERATION AND ADMINISTRATION
                          ----------------------------


     Effective Date. Subject to the terms of the Amalgamation Agreement, the
Plan shall be effective as of the Effective Date. The Plan shall be unlimited in
duration and, in the event of Plan termination, shall remain in effect as long
as any Replacement Options under it are outstanding.


     Adjustments to Shares.


     If the Company shall effect any subdivision or consolidation of shares of
     Stock or other capital readjustment, payment of stock dividend, stock
     split, combination of shares or recapitalization or other increase or
     reduction of the number of shares of Stock outstanding without receiving
     compensation therefor in money, services or property, then the Committee
     shall adjust (i) the number of shares available under any limits; (ii) the
     number of shares of Stock subject to outstanding Replacement Options; and
     (iii) the per-share price under any outstanding Replacement Option to the
     extent that the Participant is required to pay a purchase price per share
     with respect to the Replacement Option.


     If the Company is reorganized, merged or consolidated or is party to a plan
     of exchange with another corporation, pursuant to which reorganization,
     merger, consolidation or plan of exchange the shareholders of the Company
     receive any shares of stock or other securities or property, or the Company
     shall distribute securities of another corporation 
<PAGE>
 
     to its shareholders, there shall be substituted for the shares subject to
     outstanding Replacement Options an appropriate number of shares of each
     class of stock or amount of other securities or property which were
     distributed to the shareholders of the Company in respect of such shares,
     subject to the following:


        If the Committee determines that the substitution described in
     accordance with the foregoing provisions of this paragraph (b) would not be
     fully consistent with the purposes of the Plan or the purposes of the
     outstanding Replacement Options under the Plan, the Committee may make such
     other adjustments to the Replacement Options to the extent that the
     Committee determines such adjustments are consistent with the purposes of
     the Plan and of the affected Replacement Options.


        All or any of the Replacement Options may be cancelled by the Committee
     on or immediately prior to the effective date of the applicable
     transaction, but only if the Committee gives reasonable advance notice of
     the cancellation to each affected Participant, and only if either: (A) the
     Participant is permitted to exercise the Replacement Option for a
     reasonable period prior to the effective date of the cancellation; or (B)
     the Participant receives payment or other benefits that the Committee
     determines to be reasonable compensation for the value of the cancelled
     Replacement Options.

        Upon the occurrence of a reorganization of the Company or any other
     event described in this paragraph (b), any successor to the Company shall
     be substituted for the Company to the extent that the Company and the
     successor agree to such substitution.


     Upon (or, in the discretion of the Committee, immediately prior to) the
     sale to (or exchange with) a third party unrelated to the Company of all or
     substantially all of the assets of the Company, all Replacement Options
     shall be cancelled. If Replacement Options are cancelled under this
     paragraph (c), then, with respect to any affected Participant, either:


        the Participant shall be provided with reasonable advance notice of the
     cancellation, and the Participant shall be permitted to exercise the
     Replacement Option for a reasonable period prior to the effective date of
     the cancellation; or


        the Participant shall receive payment or other benefits that the
     Committee determines to be reasonable compensation for the value of the
     cancelled Replacement Options.


     The foregoing provisions of this paragraph (c) shall also apply to the sale
     of all or substantially all of the assets of the Company to a related
     party, if the Committee determines such application is appropriate.


     In determining what action, if any, is necessary or appropriate under the
     foregoing provisions of this subsection 3.2, the Committee shall act in a
     manner that it determines to be consistent with the purposes of the Plan
     and of the affected Replacement Options and, where applicable or otherwise
     appropriate, in a manner that it determines to be necessary to preserve the
     benefits and potential benefits of the affected Replacement Options for the
     Participants and the Employers.


     The existence of this Plan and the Replacement Options granted hereunder
     shall not affect in any way the right or power of the Company or its
     shareholders to make or authorize any or all adjustments,
     recapitalizations, 

<PAGE>
 
     reorganizations or other changes in the Company's capital structure or its
     business, any merger or consolidation of the Company, any issue of bonds,
     debentures, preferred or prior preference stocks ahead of or affecting the
     Company's Stock or the rights thereof, the dissolution or liquidation of
     the Company, any sale or transfer of all or any part of its assets or
     business, or any other corporate act or proceeding, whether of a similar
     character or otherwise.


     Except as expressly provided by the terms of this Plan, the issue by the
     Company of shares of stock of any class, or securities convertible into
     shares of stock of any class, for cash or property or for labor or
     services, either upon direct sale, upon the exercise of rights or warrants
     to subscribe therefor or upon conversion of shares or obligations of the
     Company convertible into such shares or other securities, shall not affect,
     and no adjustment by reason thereof shall be made with respect to
     Replacement Options then outstanding hereunder.


     Replacement Options under the Plan are subject to adjustment under this
     subsection 3.2 only during the period in which they are considered to be
     outstanding under the Plan.  For purposes of this subsection 3.2, a
     Replacement Option is considered "outstanding" on any date if the
     Participant's ability to obtain all benefits with respect to the
     Replacement Option is subject to limits imposed by the Plan (including any
     limits imposed by the agreement evidencing the grant of the Replacement
     Option).  The determination of whether a Replacement Option is outstanding
     shall be made by the Committee.


     Limit on Distribution.  Distribution of shares of Stock or other
amounts under the Plan shall be subject to the following:


     Notwithstanding any other provision of the Plan, the Company shall have no
     liability to issue any shares of Stock under the Plan or make any other
     distribution of benefits under the Plan unless such delivery or
     distribution would comply with all applicable laws and the applicable
     requirements of any securities exchange or similar entity.


     In the case of a Participant who is subject to Section 16(a) and 16(b) of
     the Securities Exchange Act of 1934, the Committee may, at any time, add
     such conditions and limitations to any Replacement Option to such
     Participant, or any feature of any such Replacement Option, as the
     Committee, in its sole discretion, deems necessary or desirable to comply
     with Section 16(a) or 16(b) and the rules and regulations thereunder or to
     obtain any exemption therefrom.


     To the extent that the Plan provides for issuance of certificates to
     reflect the transfer of shares of Stock, the transfer of such shares may,
     at the direction of the Committee, be effected on a non-certificated basis,
     to the extent not prohibited by the provisions of Rule 16b-3, applicable
     local law, the applicable rules of any stock exchange, or any other
     applicable rules.


     Withholding.  All Replacement Options and other payments under the Plan are
subject to withholding of all applicable taxes, which withholding obligations
may be satisfied, with the consent of the Committee, through the surrender of
shares of Stock which the Participant already owns, or to which a Participant is
otherwise entitled under the Plan.

     Distributions to Disabled Persons.  Notwithstanding any other provision of
the Plan, if, in the Committee's opinion, a Participant or other person entitled
to benefits under the Plan is under a legal disability or is in any way
incapacitated so as to be unable to manage his financial affairs, the Committee
may
<PAGE>
 
direct that payment be made to a relative or friend of such person for his
benefit until claim is made by a conservator or other person legally charged
with the care of his person or his estate, and such payment or distribution
shall be in lieu of any such payment to such Participant or other person.
Thereafter, any benefits under the Plan to which such Participant or other
person is entitled shall be paid to such conservator or other person legally
charged with the care of his person or his estate.


     3.6.  Transferability.  Replacement Options under the Plan are not
transferable except as designated by the Participant by will or by the laws of
descent and distribution or pursuant to a qualified domestic relations order as
defined by the Code, Title I of the Employee Retirement Income Security Act, or
the rules thereunder (a "QDRO"). To the extent that the Participant who receives
a Replacement Option under the Plan has the right to exercise such Replacement
Option, the Replacement Option may be exercised during the lifetime of the
Participant only by the Participant.


     3.7.  Administration.  The authority to control and manage the operation
and administration of the Plan shall be vested in a committee (the "Committee")
in accordance with Section 5.


     3.8.  Notices.  Any notice or document required to be filed with the
Committee under the Plan will be properly filed if delivered or mailed by
registered mail, postage prepaid, to the Committee, in care of the Company, at
its principal executive offices. The Committee may, by advance written notice to
affected persons, revise such notice procedure from time to time. Any notice
required under the Plan (other than a notice of election) may be waived by the
person entitled to notice.

     3.9.  Form and Time of Elections.  Unless otherwise specified herein, each
election required or permitted to be made by any Participant or other person
entitled to benefits under the Plan, and any permitted modification or
revocation thereof, shall be in writing filed with the Committee at such times,
in such form, and subject to such restrictions and limitations, not inconsistent
with the terms of the Plan, as the Committee shall require.

     3.10.  Agreement With Company.  At the time a Replacement Option is granted
to a Participant under the Plan, the Committee will require a Participant to
enter into an agreement with the Company in a form specified by the Committee,
agreeing to the terms and conditions of the Plan and to such additional terms
and conditions, not inconsistent with the Plan and the Amalgamation Agreement,
as the Committee may, in its sole discretion, prescribe.

     3.11.  Limitation of Implied Rights.

     (a)  Neither a Participant nor any other person shall, by reason of the
     Plan, acquire any right in or title to any assets, funds or property of the
     Employers whatsoever, including, without limitation, any specific funds,
     assets, or other property which the Employers, in their sole discretion,
     may set aside in anticipation of a liability under the Plan. A Participant
     shall have only a contractual right to the amounts, if any, payable under
     the Plan, unsecured by any assets of the Employers. Nothing contained in
     the Plan shall constitute a guarantee by any of the Employers that the
     assets of the Employers shall be sufficient to pay any benefits to any
     person.

     (b)  The Plan does not constitute a contract of employment, and selection
     as a Participant will not give any employee the right to be retained in the
     employ of an Employer or any Related Company, nor any right or claim to any
     benefit under the Plan, unless such right or claim has specifically accrued
     under the terms of the Plan. Except as otherwise provided in the Plan, no
     Replacement Option under the Plan

<PAGE>
 
     shall confer upon the holder thereof any right as a shareholder of the
     Company prior to the date on which he fulfills all service requirements and
     other conditions for receipt of such rights.

     3.12.  Benefits Under Qualified Retirement Plans.  Replacement Options to a
Participant (including the grant and the receipt of benefits) under the Plan
shall be disregarded for purposes of determining the Participant's benefits
under any Qualified Retirement Plan.

     3.13.  Evidence.  Evidence required of anyone under the Plan may be by
certificate, affidavit, document or other information which the person acting on
it considers pertinent and reliable, and signed, made or presented by the proper
party or parties.

     3.14.  Action by Employers.  Any action required or permitted to be taken
by any Employer shall be by resolution of its board of directors, or by action
of one or more members of the board (including a committee of the board) who are
duly authorized to act for the board, or (except to the extent prohibited by the
provisions of Rule 16b-3, applicable local law, the applicable rules of any
stock exchange, or any other applicable rules) by a duly authorized officer of
the Employer.

     3.15.  Gender and Number.  Where the context admits, words in any gender
shall include any other gender, words in the singular shall include the plural
and the plural shall include the singular.


                                   SECTION 4

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

     Subject to the provisions of subsection 3.2 (relating to the adjustment of
shares), and except as otherwise provided in the Plan or the agreement
evidencing the grant of the applicable Replacement Option, upon the occurrence
of a Change in Control all outstanding Replacement Options shall become fully
exercisable.

                                   ---------

     5.1.  Selection of Committee.  The Committee shall be selected by the
Board, and shall consist of not less than two members of the Board.

     5.2.  Powers of Committee.  The authority to manage and control the
operation and administration of the Plan shall be vested in the Committee,
subject to the following:

     (a)  Subject to the provisions of the Plan and the Amalgamation Agreement,
     the Committee will have the authority and discretion to select individuals
     to receive Replacement Options, to determine the time or times of receipt,
     to determine the types of Replacement Options and the number of shares
     covered by the Replacement Options, to establish the terms, conditions,
     performance criteria, restrictions, and other provisions of such
     Replacement Options, and to cancel or suspend Replacement Options. In
     making such Replacement Option determinations, the Committee may take into
     account the nature of services rendered by the respective individual, his
     present and potential contribution to the Company's success and such other
     factors as the Committee deems relevant.


     (b) The Committee will have the authority and discretion to interpret the
     Plan, to establish, amend, and rescind any rules and regulations relating
     to the Plan, to determine the

<PAGE>
 
     terms and provisions of any agreements made pursuant to the Plan, and to
     make all other determinations that may be necessary or advisable for the
     administration of the Plan.

     (c)  Any interpretation of the Plan by the Committee and any decision made
     by it under the Plan is final and binding on all persons.

     (d)  Except as otherwise expressly provided in the Plan, where the
     Committee is authorized to make a determination with respect to any
     Replacement Option, such determination shall be made at the time the
     Replacement Option is made, except that the Committee may reserve the
     authority to have such determination made by the Committee in the future
     (but only if such reservation is made at the time the Replacement Option is
     granted and is expressly stated in the agreement evidencing the grant of
     the Replacement Option).

     5.3.  Delegation by Committee.  Except to the extent prohibited by the
provisions of Rule 16b-3, applicable local law, the applicable rules of any
stock exchange, or any other applicable rules, the Committee may allocate all or
any portion of its responsibilities and powers to any one or more of its members
and may delegate all or any part of its responsibilities and powers to any
person or persons selected by it. Any such allocation or delegation may be
revoked by the Committee at any time.

     5.4.  Information to be Furnished to Committee.  The Employers and Related
Companies shall furnish the Committee with such data and information as may be
required for it to discharge its duties. The records of the Employers and
Related Companies as to an employee's or Participant's employment or service as
a director, termination of employment or termination as a director, leave of
absence, reemployment and compensation shall be conclusive on all persons unless
determined to be incorrect. Participants and other persons entitled to benefits
under the Plan must furnish the Committee such evidence, data or information as
the Committee considers desirable to carry out the terms of the Plan.

     5.5.  Liability and Indemnification of Committee.  No member or authorized
delegate of the Committee shall be liable to any person for any action taken or
omitted in connection with the administration of the Plan unless attributable to
his own fraud or willful misconduct; nor shall the Employers be liable to any
person for any such action unless attributable to fraud or willful misconduct on
the part of a director or employee of the Employers. The Committee, the
individual members thereof, and persons acting as the authorized delegates of
the Committee under the Plan, shall be indemnified by the Employers, to the
fullest extent permitted by law, against any and all liabilities, losses, costs
and expenses (including legal fees and expenses) of whatsoever kind and nature
which may be imposed on, incurred by or asserted against the Committee or its
members or authorized delegates by reason of the performance of a Committee
function if the Committee or its members or authorized delegates did not act
dishonestly or in willful violation of the law or regulation under which such
liability, loss, cost or expense arises. This indemnification shall not
duplicate but may supplement any coverage available under any applicable
insurance.

                                   ---------

                           AMENDMENT AND TERMINATION
                           -------------------------

     The Board may, at any time, amend or terminate the Plan, provided that,
subject to subsection 3.2 (relating to certain adjustments to shares), no
amendment or termination may adversely affect the rights of any Participant or
beneficiary under any Replacement Option made under the Plan prior to the date
such amendment is adopted by the Board.

such former Money Market Quote.  The Agent's notice to the Borrower shall
specify (A) the aggregate principal amount of Money Market Loans for which
offers have been received for each Interest Period specified in the related
Money Market Quote Request, (B) the respective principal amounts and Money
Market Margins or Money Market Absolute Rates, as the case may be, so offered
and (C) if applicable, limitations on the aggregate principal amount of Money
Market Loans for which offers in any single Money Market Quote may be accepted.

          (f)  Acceptance and Notice by Borrower.  Not later than 10:30 A.M.
(New York City time) on (x) the third Euro-Dollar Business Day prior to the
proposed date of Borrowing, in the case of a LIBOR Auction or (y) the 

                                      16
<PAGE>
 
proposed date of Borrowing, in the case of an Absolute Rate Auction (or, in
either case, such other time or date as the Borrower and the Agent shall have
mutually agreed and shall have notified to the Banks not later than the date of
the Money Market Quote Request for the first LIBOR Auction or Absolute Rate
Auction for which such change is to be effective), the Borrower shall notify the
Agent of its acceptance or non-acceptance of the offers so notified to it
pursuant to subsection (e). In the case of acceptance, such notice (such notice
to be signed by any two of the President or Executive Vice-President(s) or any
one of the President or Executive Vice-President(s) together with any one of the
Senior Vice-President(s) signing jointly and hereinafter referred to as a
"Notice of Money Market Borrowing") shall specify the aggregate principal amount
of offers for each Interest Period that are accepted. The Borrower may accept
any Money Market Quote in whole or in part; provided that:

          (i)  the aggregate principal amount of each Money Market Borrowing may
     not exceed the applicable amount set forth in the related Money Market
     Quote Request,

         (ii)  the principal amount of each Money Market Borrowing must be
     $5,000,000 or a larger multiple of $1,000,000,

        (iii)  acceptance of offers may only be made on the basis of ascending
     Money Market Margins or Money Market Absolute Rates, as the case may be,
     and

         (iv)  the Borrower may not accept any offer that is described in
     subsection (d)(iii) or that otherwise fails to comply with the requirements
     of this Agreement.

          (g) Allocation by Agent. If offers are made by two or more Banks with
the same Money Market Margins or Money Market Absolute Rates, as the case may
be, for a greater aggregate principal amount than the amount in respect of which
such offers are accepted for the related Interest Period, the principal amount
of Money Market Loans in respect of which such offers are accepted shall be
allocated by the Agent among such Banks as nearly as possible (in multiples of
$1,000,000, as the Agent may deem appropriate) in proportion to the aggregate
principal amounts of such offers. Determinations by the Agent of the amounts of
Money Market Loans shall be conclusive in the absence of manifest error.

          SECTION 2.04.  Notice to Banks; Funding of Loans.

                                      17
<PAGE>
 
          (a)  Upon receipt of a Notice of Borrowing, the Agent shall promptly
notify each Bank of the contents thereof and of such Bank's share (if any) of
such Borrowing and such Notice of Borrowing shall not thereafter be revocable by
the Borrower.

          (b)  Not later than 12:00 Noon (New York City time) on the date of
each Borrowing, each Bank participating therein shall (except as provided in
subsection (c) of this Section) make available its share of such Borrowing, in
Federal or other funds immediately available in New York City, to the Agent at
its address referred to in Section 10.01.  Unless the Agent determines that any
applicable condition specified in Article III has not been satisfied, the Agent
will make the funds so received from the Banks available to the Borrower at the
Agent's aforesaid address.

          (c)  If any Bank makes a new Loan hereunder on a day on which the
Borrower is to repay all or any part of an outstanding Loan from such Bank, such
Bank shall apply the proceeds of its new Loan to make such repayment and only an
amount equal to the difference (if any) between the amount being borrowed and
the amount being repaid shall be made available by such Bank to the Agent as
provided in subsection (b), or remitted by the Borrower to the Agent as provided
in Section 2.12, as the case may be.

          (d) Unless the Agent shall have received notice from a Bank prior to
the date of any Borrowing that such Bank will not make available to the Agent
such Bank's share of such Borrowing, the Agent may assume that such Bank has
made such share available to the Agent on the date of such Borrowing in
accordance with subsections (b) and (c) of this Section 2.04 and the Agent may,
in reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If and to the extent that such Bank shall not have so made
such share available to the Agent, such Bank and the Borrower severally agree to
repay to the Agent forthwith on demand such corresponding amount together with
interest thereon, for each day from the date such amount is made available to
the Borrower until the date such amount is repaid to the Agent, at (i) in the
case of the Borrower, a rate per annum equal to the interest rate applicable
thereto pursuant to Section 2.07 and (ii) in the case of such Bank, the Federal
Funds Rate. If such Bank shall repay to the Agent such corresponding amount,
such amount so repaid shall constitute such Bank's Loan included in such
Borrowing for purposes of this Agreement.

          SECTION 2.05.  Notes.  (a)  The Loans of each Bank shall be evidenced
by a single Note payable to the order of 

                                      18
<PAGE>
 
such Bank for the account of its Applicable Lending Office in an amount equal to
the aggregate unpaid principal amount of such Bank's Loans.

          (b)  Each Bank may, by notice to the Borrower and the Agent, request
that its Loans of a particular type be evidenced by a separate Note in an amount
equal to the aggregate unpaid principal amount of such Loans.  Each such Note
shall be in substantially the form of Exhibit A hereto with appropriate
modifications to reflect the fact that it evidences solely Loans of the relevant
type.  Each reference in this Agreement to the "Note" of such Bank shall be
deemed to refer to and include any or all of such Notes, as the context may
require.

          (c)  Upon receipt of each Bank's Note pursuant to Section 3.01(a), the
Agent shall forward such Note to such Bank.  Each Bank shall record the date,
amount, type and maturity of each Loan made by it and the date and amount of
each payment of principal made by the Borrower with respect thereto, and may, if
such Bank so elects in connection with any transfer or enforcement of its Note,
endorse on the schedule forming a part thereof appropriate notations to evidence
the foregoing information with respect to each such Loan then outstanding;
provided that the failure of any Bank to make any such recordation or
endorsement shall not affect the obligations of the Borrower hereunder or under
the Notes.  Each Bank is hereby irrevocably authorized by the Borrower so to
endorse its Note and to attach to and make a part of its Note a continuation of
any such schedule as and when required.

          SECTION 2.06.  Maturity of Loans.  Each Loan included in any Borrowing
shall mature, and the principal amount thereof shall be due and payable, on the
last day of the Interest Period applicable to such Borrowing.

          SECTION 2.07. Interest Rates. (a) Each Base Rate Loan shall bear
interest on the outstanding principal amount thereof, for each day from the date
such Loan is made until it becomes due, at a rate per annum equal to the Base
Rate for such day. Such interest shall be payable for each Interest Period on
the last day thereof. Any overdue principal of or interest on any Base Rate Loan
shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the sum of 2% plus the rate otherwise applicable to Base Rate
Loans for such day.

          (b)  Each CD Loan shall bear interest on the outstanding principal
amount thereof, for each day during the Interest Period applicable thereto, at a
rate per annum 

                                      19
<PAGE>
 
equal to the sum of the CD Margin plus the Adjusted CD Rate applicable to such
Interest Period; provided that if any CD Loan or any portion thereof shall, as a
result of clause (2)(b) of the definition of Interest Period, have an Interest
Period of less than 30 days, such portion shall bear interest during such
Interest Period at the rate applicable to Base Rate Loans during such period.
Such interest shall be payable for each Interest Period on the last day thereof
and, if such Interest Period is longer than 90 days, at intervals of 90 days
after the first day thereof. Any overdue principal of or interest on any CD Loan
shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the sum of 2% plus the higher of (i) the sum of the CD Margin
plus the Adjusted CD Rate applicable to the Interest Period for such Loan and
(ii) the rate applicable to Base Rate Loans for such day.

          "CD Margin" means 0.400% per annum.

          The "Adjusted CD Rate" applicable to any Interest Period means a rate
per annum determined pursuant to the following formula:
 
 
                   [ CDBR       ]*
          ACDR  =  [ ---------- ]  + AR
                   [ 1.00 - DRP ]
 
          ACDR  =  Adjusted CD Rate
          CDBR  =  CD Base Rate
           DRP  =  Domestic Reserve Percentage
            AR  =  Assessment Rate

     ----------------
     *  The amount in brackets being rounded upward, if
     necessary, to the next higher 1/100 of 1%


          The "CD Base Rate" applicable to any Interest Period is the rate of
interest determined by the Agent to be the average (rounded upward, if
necessary, to the next higher 1/100 of 1%) of the prevailing rates per annum bid
at 10:00 A.M. (New York City time) (or as soon thereafter as practicable) on the
first day of such Interest Period by two or more New York certificate of deposit
dealers of recognized standing for the purchase at face value from each CD
Reference Bank of its certificates of deposit in an amount comparable to the
principal amount of the CD Loan of such CD Reference Bank to which such Interest
Period applies and having a maturity comparable to such Interest Period.

                                      20
<PAGE>
 
          "Domestic Reserve Percentage" means for any day that percentage
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement (including without limitation any
basic, supplemental or emergency reserves) for a member bank of the Federal
Reserve System in New York City with deposits exceeding five billion dollars in
respect of new non-personal time deposits in dollars in New York City having a
maturity comparable to the related Interest Period and in an amount of $100,000
or more.  The Adjusted CD Rate shall be adjusted automatically on and as of the
effective date of any change in the Domestic Reserve Percentage.

          "Assessment Rate" means for any day the annual assessment rate in
effect on such day which is payable by a member of the Bank Insurance Fund
classified as adequately capitalized and within supervisory subgroup "A" (or a
comparable successor assessment risk classification) within the meaning of 12
C.F.R. (S) 327.4(a) (or any successor provision) to the Federal Deposit
Insurance Corporation (or any successor) for such Corporation's (or such
successor's) insuring time deposits at offices of such institution in the United
States.  The Adjusted CD Rate shall be adjusted automatically on and as of the
effective date of any change in the Assessment Rate.

          (c)  Each Euro-Dollar Loan shall bear interest on the outstanding
principal amount thereof, for each day during the Interest Period applicable
thereto, at a rate per annum equal to the sum of the Euro-Dollar Margin for such
day plus the London Interbank Offered Rate applicable to such Interest Period.
Such interest shall be payable for each Interest Period on the last day thereof
and, if such Interest Period is longer than three months, at intervals of three
months after the first day thereof.

          "Euro-Dollar Margin" means 0.285% per annum.

          The "London Interbank Offered Rate" applicable to any Interest Period
means the average (rounded upward, if necessary, to the next higher 1/16 of 1%)
of the respective rates per annum at which deposits in dollars are offered to
each of the Euro-Dollar Reference Banks in the London interbank market at
approximately 11:00 A.M. (London time) two Euro-Dollar Business Days before the
first day of such Interest Period in an amount approximately equal to the
principal amount of the Euro-Dollar Loan of such Euro-Dollar Reference Bank to
which such Interest Period is to apply and for a period of time comparable to
such Interest Period.

                                       21
<PAGE>
 
          (d)  Any overdue principal of or interest on any Euro-Dollar Loan
shall bear interest, payable on demand, for each day until paid at a rate per
annum equal to the higher of (i) the sum of 2% plus the Euro-Dollar Margin plus
the London Interbank Offered Rate applicable to the Interest Period for such
Loan and (ii) the sum of 2% plus the Euro-Dollar Margin plus the quotient
obtained (rounded upward, if necessary, to the next higher 1/100 of 1%) by
dividing (x) the average (rounded upward, if necessary, to the next higher 1/16
of 1%) of the respective rates per annum at which one day (or, if such amount
due remains unpaid more than three Euro-Dollar Business Days, then for such
other period of time not longer than six months as the Agent may select)
deposits in dollars in an amount approximately equal to such overdue payment due
to each of the Euro-Dollar Reference Banks are offered to such Euro-Dollar
Reference Bank in the London interbank market for the applicable period
determined as provided above by (y) 1.00 minus the Euro-Dollar Reserve
Percentage (or, if the circumstances described in clause (a) or (b) of Section
8.01 shall exist, at a rate per annum equal to the sum of 2% plus the rate
applicable to Base Rate Loans for such day).

          (e)  Subject to Section 8.01(a), each Money Market LIBOR Loan shall
bear interest on the outstanding principal amount thereof, for the Interest
Period applicable thereto, at a rate per annum equal to the sum of the London
Interbank Offered Rate for such Interest Period (determined in accordance with
Section 2.07(c) as if the related Money Market LIBOR Borrowing were a Committed
Euro-Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the
Bank making such Loan in accordance with Section 2.03.  Each Money Market
Absolute Rate Loan shall bear interest on the outstanding principal amount
thereof, for the Interest Period applicable thereto, at a rate per annum equal
to the Money Market Absolute Rate quoted by the Bank making such Loan in
accordance with Section 2.03.  Such interest shall be payable for each Interest
Period on the last day thereof and, if such Interest Period is longer than three
months, at intervals of three months after the first day thereof.  Any overdue
principal of or interest on any Money Market Loan shall bear interest, payable
on demand, for each day until paid at a rate per annum equal to the sum of 2%
plus the Base Rate for such day.

          (f)  The Agent shall determine each interest rate applicable to the
Loans hereunder.  The Agent shall give prompt notice to the Borrower and the
participating Banks of each rate of interest so determined, and its
determination 

                                       22
<PAGE>
 
thereof shall be conclusive in the absence of manifest error.

          (g)  Each Reference Bank agrees to use its best efforts to furnish
quotations to the Agent as contemplated by this Section.  If any Reference Bank
does not furnish a timely quotation, the Agent shall determine the relevant
interest rate on the basis of the quotation or quotations furnished by the
remaining Reference Bank or Banks or, if none of such quotations is available on
a timely basis, the provisions of Section 8.01 shall apply.

          SECTION 2.08.  Facility Fee.  The Borrower shall pay to the Agent for
the account of the Banks ratably a facility fee at the rate of 0.090% per annum.
Such facility fee shall accrue (i) from and including the Closing Date to but
excluding the Termination Date (or earlier date of termination of the
Commitments in their entirety), on the daily aggregate amount of the Commitments
(whether used or unused) and (ii) from and including the Termination Date or
such earlier date of termination to but excluding the date the Loans shall be
repaid in their entirety, on the daily aggregate outstanding principal amount of
the Loans.  Accrued fees under this Section shall be payable quarterly in
arrears on each March 31, June 30, September 30 and December 31 and upon the
date of termination of the Commitments in their entirety (and, if later, the
date the Loans shall be repaid in their entirety).

          SECTION 2.09.  Optional Termination or Reduction of Commitments.  The
Borrower may, upon at least three Domestic Business Days' notice to the Agent,
(i) terminate the Commitments at any time, if no Loans are outstanding at such
time or (ii) ratably reduce from time to time by an aggregate amount of
$25,000,000 or any larger multiple of $5,000,000, the aggregate amount of the
Commitments in excess of the aggregate outstanding principal amount of the
Loans.  Upon receipt of any notice pursuant to this Section 2.09, the Agent
shall promptly notify the Banks of the contents of such notice.

          SECTION 2.10.  Scheduled Termination of Commitments.  The Commitments
shall terminate on the Termination Date, and any Loans then outstanding
(together with accrued interest thereon) shall be due and payable on such date.

          SECTION 2.11.  Optional Prepayments.  (a)  Subject in the case of any
Fixed Rate Borrowing to Section 2.13, the Borrower may, in the case of any CD
Borrowing, upon at least three Domestic Business Days' notice to the Agent,
prepay 

                                       23
<PAGE>
 
such CD Borrowing, or, in the case of any other Domestic Borrowing (or
any Money Market Borrowing bearing interest at the Base Rate pursuant to Section
8.01(a)), upon at least one Domestic Business Day's notice to the Agent, prepay
such other Domestic Borrowing, or in the case of any Euro-Dollar Borrowing, upon
at least three Euro-Dollar Business Days' notice to the Agent, prepay any Euro-
Dollar Borrowing, in each case in whole at any time, or from time to time in
part in amounts aggregating $5,000,000 or any larger multiple of $1,000,000, by
paying the principal amount to be prepaid together with accrued interest thereon
to the date of prepayment.  Each such optional prepayment shall be applied to
prepay ratably the Loans of the several Banks included in such Borrowing.

          (b)  Except as provided in Section 2.11(a), the Borrower may not
prepay all or any portion of the principal amount of any Money Market Loan prior
to the maturity thereof.

          (c)  Upon receipt of a notice of prepayment pursuant to this Section,
the Agent shall promptly notify each Bank of the contents thereof and of such
Bank's ratable share (if any) of such prepayment and such notice shall not
thereafter be revocable by the Borrower.

          SECTION 2.12.  General Provisions as to Payments.  (a)  The Borrower
shall make each payment of principal of, and interest on, the Loans and of fees
hereunder, not later than 2:00 P.M. (New York City time) on the date when due,
in Federal or other funds immediately available in New York City and in the
lawful currency of the United States, to the Agent at its address referred to in
Section 10.01.  The Agent will promptly distribute to each Bank its ratable
share of each such payment received by the Agent for the account of the Banks.
Whenever any payment of principal of, or interest on, the Domestic Loans or of
fees shall be due on a day which is not a Domestic Business Day, the date for
payment thereof shall be extended to the next succeeding Domestic Business Day.
Whenever any payment of principal of, or interest on, the Euro-Dollar Loans
shall be due on a day which is not a Euro-Dollar Business Day, the date for
payment thereof shall be extended to the next succeeding Euro-Dollar Business
Day unless such Euro-Dollar Business Day falls in another calendar month, in
which case the date for payment thereof shall be the next preceding Euro-Dollar
Business Day.  Whenever any payment of principal of, or interest on, the Money
Market Loans shall be due on a day which is not a Euro-Dollar Business Day, the
date for payment thereof shall be extended to the next succeeding Euro-Dollar
Business Day.  If the date for any payment of 

                                       24
<PAGE>
 
principal is extended by operation of law or otherwise, interest thereon shall
be payable for such extended time.

          (b)  Unless the Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Banks hereunder that the
Borrower will not make such payment in full, the Agent may assume that the
Borrower has made such payment in full to the Agent on such date and the Agent
may, in reliance upon such assumption, cause to be distributed to each Bank on
such due date an amount equal to the amount then due such Bank.  If and to the
extent that the Borrower shall not have so made such payment, each Bank shall
repay to the Agent forthwith on demand such amount distributed to such Bank
together with interest thereon, for each day from the date such amount is
distributed to such Bank until the date such Bank repays such amount to the
Agent, at the Federal Funds Rate.

          SECTION 2.13.  Funding Losses.  If the Borrower makes any payment of
principal with respect to any Fixed Rate Loan (pursuant to Article II, VI or
VIII or otherwise) on any day other than the last day of the Interest Period
applicable thereto, or the last day of an applicable period fixed pursuant to
Section 2.07(d), or if the Borrower fails to borrow or prepay any Fixed Rate
Loans after notice has been given to any Bank in accordance with Section 2.04(a)
or 2.11(c), the Borrower shall reimburse each Bank within 15 days after demand
for any resulting loss or expense incurred by it (or by an existing or, in the
case of the failure of the Borrower to borrow any Fixed Rate Loans, prospective
Participant in the related Loan), including (without limitation) any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period after any such payment or failure to
borrow or prepay, provided that such Bank shall have delivered to the Borrower a
certificate as to the amount of such loss or expense and setting forth the
calculation thereof, which certificate shall be conclusive in the absence of
manifest error.

          SECTION 2.14. Computation of Interest and Fees. Interest based on the
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and all
facility fees shall be computed on the basis of a year of 360 days and paid for
the actual number of days elapsed (including the first day but excluding the
last day).

                                       25
<PAGE>
 
          SECTION 2.15.  Regulation D Compensation.  For so long as any Bank
maintains reserves against "Eurocurrency liabilities" (or any other category of
liabilities which includes deposits by reference to which the interest rate on
Euro-Dollar Loans is determined or any category of extensions of credit or other
assets which includes loans by a non-United States office of such Bank to United
States residents), and as a result the cost to such Bank (or its Euro-Dollar
Lending Office) of making or maintaining its Euro-Dollar Loans is increased,
then such Bank may require the Borrower to pay, contemporaneously with each
payment of interest on the Euro-Dollar Loans, additional interest on the related
Euro-Dollar Loan of such Bank at a rate per annum up to but not exceeding the
excess of (i) (A) the applicable London Interbank Offered Rate divided by (B)
one minus the Euro-Dollar Reserve Percentage over (ii) the applicable London
Interbank Offered Rate. Any Bank wishing to require payment of such additional
interest (x) shall so notify the Borrower and the Agent, in which case such
additional interest on the Euro-Dollar Loans of such Bank shall be payable to
such Bank at the place indicated in such notice with respect to each Interest
Period commencing at least three Euro-Dollar Business Days after the giving of
such notice and (y) shall furnish to the Borrower at least five Euro-Dollar
Business Days prior to each date on which interest is payable on the Euro-Dollar
Loans an officer's certificate setting forth the amount to which such Bank is
then entitled under this Section (which shall be consistent with such Bank's
good faith estimate of the level at which the related reserves are maintained by
it). Each such certificate shall be accompanied by such information as the
Borrower may reasonably request as to the computation set forth therein.

                                  ARTICLE III

termination of the Commitments (as defined in the Credit Agreement referred to
below in this clause (x)) under the Credit Agreement dated as of November 17,
1995 among the Borrower, the Guarantors, the banks listed therein and Morgan
Guaranty Trust Company of New York, as agent, and payment in full of all amounts
owing thereunder to any of such banks or such agent and (y) receipt by the Agent
of the following documents, each dated the Closing Date unless otherwise

     existence of the Borrower and the Guarantors, the corporate authority for
     and the validity of this Agreement and the Notes, and any other matters
     relevant hereto, all in form and substance satisfactory to the Agent.

The Agent shall promptly notify the Borrower and the Banks of the Closing Date,

<PAGE>
 
     period shall cease to constitute a majority of the board of directors of
     the Borrower; or either Guarantor shall cease to be a Wholly-Owned
     Consolidated Subsidiary of the Borrower;

          (j)  any court or arbitrator or any governmental body, agency or
     official which has jurisdiction in the matter shall decide, rule or order
     that any provision of any of the Financing Documents is invalid or
     unenforceable in any material respect, or any Obligor shall so assert in
     writing; or

          (k)  the registration of either Guarantor as an insurer shall be
     revoked, suspended or otherwise have restrictions or conditions placed upon
     it unless, in the case of the placing of any such restrictions or

then, and in every such event, the Agent shall (i) if requested by Banks having

accrued interest thereon) to be, and the Notes (together with accrued interest
thereon) shall thereupon become, immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Obligors; provided that in the case of any of the Events of
Default specified in clause (g) above with respect to any Obligor, without any
notice to any Obligor or any other act by the Agent or the Banks, the

                                  ARTICLE VII
                                        
                                   THE AGENT
                                        

          SECTION 7.01.  Appointment and Authorization.  Each Bank irrevocably
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under the Financing Documents as are delegated to the
Agent by the terms hereof and thereof, together with all such powers as are
reasonably incidental thereto.

          SECTION 7.02.  Agent and Affiliates.  Morgan Guaranty Trust Company of
New York shall have the same rights and powers under this Agreement as any other
Bank and may exercise or refrain from exercising the same as though it were not
the Agent, and Morgan Guaranty Trust Company of New York and its affiliates may
accept deposits from, lend money to, and generally engage in any kind of
business with the Borrower or any Subsidiary or affiliate of the Borrower as if
it were not the Agent hereunder.

          SECTION 7.03.  Action by Agent.  The obligations of the Agent under
this Agreement are only those expressly set forth herein.  Without limiting the
generality of the foregoing, the Agent shall not be required to take any action
with respect to any Default, except as expressly provided in Article VI.

          SECTION 7.04.  Consultation with Experts.  The Agent may consult with
legal counsel (who may be counsel for the Borrower), independent public
accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
advice of such counsel, accountants or experts.

          SECTION 7.05.  Liability of Agent.  Neither the Agent nor any of its
affiliates nor any of their respective directors, officers, agents or employees
shall be liable for any action taken or not taken by it in connection herewith
(i) with the consent or at the request of the Required Banks or (ii) in the
absence of its own gross negligence or willful misconduct.  Neither the Agent
nor any of its affiliates nor any of their respective directors, officers,
agents or employees shall be responsible for or have any duty to ascertain,
inquire into or verify (i) any statement, warranty or representation made in
connection with the Financing Documents or any borrowing hereunder; (ii) the
performance or observance of any of the covenants or agreements of any Obligor;
(iii) the satisfaction of any
                                       42
<PAGE>
 
condition specified in Article III, except receipt of items required to be
delivered to the Agent; or (iv) the validity, effectiveness or genuineness of
any Financing Document or any other instrument or writing furnished in
connection herewith. The Agent shall not incur any liability by acting in
reliance upon any notice, consent, certificate, statement, or other writing
(which may be a bank wire, telex, facsimile transmission or similar writing)
believed by it to be genuine or to be signed by the proper party or parties.

          SECTION 7.06.  Indemnification.  Each Bank shall, ratably in
accordance with its Commitment, indemnify the Agent, its affiliates and their
respective directors, officers, agents and employees (to the extent not
reimbursed by the Borrower) against any cost, expense (including counsel fees
and disbursements), claim, demand, action, loss or liability (except such as
result from such indemnitees' gross negligence or willful misconduct) that such
indemnitees may suffer or incur in connection with the Financing Documents or
any action taken or omitted by such indemnitees hereunder or thereunder.

          SECTION 7.07.  Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement. Each Bank also
acknowledges that it will, independently and without reliance upon the Agent or
any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

          SECTION 7.08.  Successor Agent.  The Agent may resign at any time by
giving notice thereof to the Banks and the Borrower. Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent, which
successor Agent shall be reasonably acceptable to the Borrower. If no successor
Agent shall have been so appointed by the Required Banks, and shall have
accepted such appointment, within 30 days after the retiring Agent gives notice
of resignation, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a commercial bank organized or licensed under
the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $50,000,000. Upon the acceptance of its
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the

                                      43
<PAGE>
 
rights and duties of the retiring Agent, and the retiring Agent shall be
discharged from its duties and obligations hereunder. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent.

          SECTION 7.09.  Agent's Fee.  The Borrower shall pay to the Agent for
its own account fees in the amounts and at the times previously agreed upon
between the Borrower and the Agent.


                                 ARTICLE VIII
                                        
                            CHANGE IN CIRCUMSTANCES
                                        

          SECTION 8.01.  Basis for Determining Interest Rate Inadequate or
Unfair. If on or prior to the first day of any Interest Period for any Fixed
Rate Borrowing:

          (a)  the Agent is advised by the Reference Banks that deposits in
     dollars (in the applicable amounts) are not being offered to the Reference
     Banks in the relevant market for such Interest Period, or

          (b)  in the case of a Committed Borrowing, Banks having 50% or more of
     the aggregate amount of the Commitments advise the Agent that the Adjusted
     CD Rate or the London Interbank Offered Rate, as the case may be, as
     determined by the Agent will not adequately and fairly reflect the cost to
     such Banks of funding their CD Loans or Euro-Dollar Loans, as the case may
     be, for such Interest Period,

the Agent shall forthwith give notice thereof to the Borrower and the Banks,
whereupon until the Agent notifies the Borrower that the circumstances giving
rise to such suspension no longer exist, the obligations of the Banks to make CD
Loans or Euro-Dollar Loans, as the case may be, shall be suspended. Unless the
Borrower notifies the Agent at least two Domestic Business Days before the date
of any Fixed Rate Borrowing for which a Notice of Borrowing has previously been
given that it elects not to borrow on such date, (i) if such Fixed Rate
Borrowing is a Committed Borrowing, such Borrowing shall instead be made as a
Base Rate Borrowing and (ii) if such Fixed Rate Borrowing is a Money Market
LIBOR Borrowing, the Money Market LIBOR Loans comprising such Borrowing shall
bear interest for each day from and including the first day to but excluding the
last

                                      44
<PAGE>
 
day of the Interest Period applicable thereto at the Base Rate for such day.

          SECTION 8.02.  Illegality.  If, on or after the date of this
Agreement, the adoption of any applicable law, rule or regulation, or any change
in any applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Euro-Dollar Lending Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency shall make it unlawful or impossible for any
Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-
Dollar Loans and such Bank shall so notify the Agent, the Agent shall forthwith
give notice thereof to the other Banks and the Borrower, whereupon until such
Bank notifies the Borrower and the Agent that the circumstances giving rise to
such suspension no longer exist, the obligation of such Bank to make Euro-Dollar
Loans shall be suspended. Before giving any notice to the Agent pursuant to this
Section, such Bank shall designate a different Euro-Dollar Lending Office if
such designation will avoid the need for giving such notice and will not, in the
judgment of such Bank, be otherwise disadvantageous to such Bank. If such Bank
shall determine that it may not lawfully continue to maintain and fund any of
its outstanding Euro-Dollar Loans to maturity and shall so specify in such
notice, the Borrower shall immediately prepay in full the then outstanding
principal amount of each such Euro-Dollar Loan, together with accrued interest
thereon. Concurrently with prepaying each such Euro-Dollar Loan, the Borrower
shall borrow a Base Rate Loan in an equal principal amount from such Bank (on
which interest and principal shall be payable contemporaneously with the related
Euro-Dollar Loans of the other Banks), and such Bank shall make such a Base Rate
Loan.

          SECTION 8.03.  Increased Cost and Reduced Return.  (a)  If on or after
(x) the date hereof, in the case of any Committed Loan or any obligation to make
Committed Loans or (y) the date of the related Money Market Quote, in the case
of any Money Market Loan, the adoption of any applicable law, rule or
regulation, or any change in any applicable law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank (or its Applicable Lending
Office) with any request or directive (whether or not having the force of law)
of any

                                      45
<PAGE>
 
such authority, central bank or comparable agency shall impose, modify or deem
applicable any reserve (including, without limitation, any such requirement
imposed by the Board of Governors of the Federal Reserve System, but excluding
(i) with respect to any CD Loan any such requirement included in an applicable
Domestic Reserve Percentage and (ii) with respect to any Euro-Dollar Loan any
such requirement included in an applicable Euro-Dollar Reserve Percentage),
special deposit, insurance assessment (excluding, with respect to any CD Loan,
any such requirement reflected in an applicable Assessment Rate) or similar
requirement against assets of, deposits with or for the account of, or credit
extended by, any Bank (or its Applicable Lending Office) or shall impose on any
Bank (or its Applicable Lending Office) or on the United States market for
certificates of deposit or the London interbank market any other condition
affecting its Fixed Rate Loans, its Note or its obligation to make Fixed Rate
Loans and the result of any of the foregoing is to increase the cost to such
Bank (or its Applicable Lending Office) of making or maintaining any Fixed Rate
Loan, or to reduce the amount of any sum received or receivable by such Bank (or
its Applicable Lending Office) under this Agreement or under its Note with
respect thereto, by an amount deemed by such Bank to be material, then, within
15 days after demand by such Bank (with a copy to the Agent), the Borrower shall
pay to such Bank such additional amount or amounts as will compensate such Bank
for such increased cost or reduction.

          (b)  If any Bank shall have determined that, after the date hereof,
the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any such law, rule or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Bank (or its Parent) as a consequence of such Bank's
obligations hereunder to a level below that which such Bank (or its Parent)
could have achieved but for such adoption, change, request or directive (taking
into consideration its policies with respect to capital adequacy) by an amount
deemed by such Bank to be material, then from time to time, within 15 days after
demand by such Bank (with a copy to the Agent), the Borrower shall pay to such
Bank such additional amount or amounts as will compensate such Bank (or its
Parent) for such reduction.

                                      46
<PAGE>
 
          (c)  Each Bank will promptly notify the Borrower and the Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle such Bank to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank
claiming compensation under this Section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

          SECTION 8.04.  Taxes.  (a)  Any and all payments by any Obligor
hereunder shall be made free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all penalties, interest, expenses and similar liabilities with respect
thereto, excluding (i) in the case of each Bank and the Agent, taxes imposed on
its income, and franchise and similar taxes imposed on it, by the jurisdiction
under the laws of which such Bank or the Agent, as the case may be, shall be
organized or any political subdivision thereof, (ii) in the case of each Bank,
taxes imposed on its income, and franchise and similar taxes imposed on it, by
the jurisdiction of such Bank's Applicable Lending Office or any political
subdivision thereof or in which such Bank's principal executive office is
located or any political subdivision thereof and (iii) any Taxes imposed as a
result of a change of such Bank's Applicable Lending Office to the extent such
Taxes would not have been imposed absent such change; provided however, that (x)
a change in such Bank's Applicable Lending Office to which the Obligor has
consented and (y) a change in such Bank's Applicable Lending Office as a result
of legal or regulatory restrictions shall not constitute a change for the
purposes of this Section 8.04 (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). Each Obligor agrees that, if any Obligor shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder to any Bank
or the Agent, (A) the sum payable to such Bank or the Agent shall be increased
as may be necessary so that after making all required deductions for Taxes
(including deductions applicable to additional sums payable under this Section
8.04), such Bank or the Agent, as the case may be, shall receive an amount equal
to the sum it would have received had no such deductions been made, (B) such
Obligor shall make such deductions and (C) such Obligor shall pay the full


                                      47
<PAGE>
 
amount deducted to the relevant taxing authority or other authority in
accordance with applicable law.

          (b)  In addition, each Obligor agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which shall arise from any payment made under, or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement (all such taxes, charges or levies being hereinafter referred to as
"Other Taxes").

          (c) Each Obligor agrees to indemnify each Bank and the Agent for the
full amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed
on amounts payable under this Section 8.04) paid by such Bank or the Agent or
any penalties, interest, expenses and similar liabilities arising therefrom or
with respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted provided that such Bank has acted in good faith with respect to
such Taxes or Other Taxes and that such Bank reasonably cooperates with the
Obligors in challenging such Taxes or Other Taxes.  Each indemnification under
this paragraph (c) shall be made within 30 days from the date such Bank or the
Agent makes demand therefor.

          (d)  Each Bank shall use reasonable efforts (consistent with legal and
regulatory restrictions) (x) to file any certificate or document or to furnish
any information as reasonably requested by any Obligor pursuant to any
applicable treaty, law, rule or regulation or (y) to designate a different
Lending Office if the making of such a filing, the furnishing of such
information or the designation of such other Lending Office would avoid the need
for or reduce the amount of any additional amounts payable by any Obligor
pursuant to this Section 8.04 and would not, in the reasonable judgment of such
Bank, be disadvantageous to such Bank.  Notwithstanding the foregoing, it is
understood and agreed that nothing in this Section 8.04 shall interfere with the
rights of any Bank to conduct its fiscal or tax affairs in such manner as it
deems fit.

          (e)  Within 90 days after the date of any payment of Taxes, the
Obligors will furnish to the Agent notarized copies for each Bank of the
original receipt evidencing payment thereof.  If no Taxes shall be payable in
respect of any payment under this Agreement, the Obligors will, upon the
reasonable request of the Agent, furnish to the Agent a certificate in form
reasonably acceptable to the Agent's counsel confirming that such payment is
exempt from or not subject to Taxes.

                                       48
<PAGE>
 
          (f)  For any period with respect to which a Bank has failed to provide
the Obligors with the appropriate form pursuant to Section 8.04(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which such form originally was required to be provided), such Bank
shall not be entitled to indemnification under Section 8.04(a) or (b) with
respect to Taxes imposed by the United States; provided that if a Bank, which is
otherwise exempt from or subject to a reduced rate of withholding tax, becomes
subject to Taxes because of its failure to deliver a form required hereunder,
the Obligors shall take such steps as such Bank shall reasonably request to
assist such Bank to recover such Taxes.

          SECTION 8.05.  Base Rate Loans Substituted for Affected Fixed Rate
Loans.  If (i) the obligation of any Bank to make Euro-Dollar Loans has been
suspended pursuant to Section 8.02 or (ii) any Bank has demanded compensation
under Section 8.03 or 8.04 with respect to its CD Loans or Euro-Dollar Loans and
the Borrower shall, by at least five Euro-Dollar Business Days' prior notice to
such Bank through the Agent, have elected that the provisions of this Section
shall apply to such Bank, then, unless and until such Bank notifies the Borrower
that the circumstances giving rise to such suspension or demand for compensation
no longer exist:

          (a)  all Loans which would otherwise be made by such Bank as CD Loans
     or Euro-Dollar Loans, as the case may be, shall be made instead as Base
     Rate Loans (on which interest and principal shall be payable
     contemporaneously with the related Fixed Rate Loans of the other Banks),
     and

          (b)  after each of its CD Loans or Euro-Dollar Loans, as the case may
     be, has been repaid, all payments of principal which would otherwise be
     applied to repay such Fixed Rate Loans shall be applied to repay its Base
     Rate Loans instead.


                                  ARTICLE IX

                                   GUARANTY

          SECTION 9.01.  The Guaranty.  Each Guarantor hereby unconditionally,
absolutely and irrevocably guarantees the full and punctual payment (whether at
stated maturity, upon acceleration or otherwise) of all amounts payable by the
Borrower under the Financing Documents including, without limitation, the
principal of and interest on each Note issued by the Borrower pursuant to this

                                       49
<PAGE>
 
Agreement.  Upon failure by the Borrower to pay punctually any such amount, each
Guarantor shall forthwith on demand pay the amount not so paid at the place and
in the manner specified in this Agreement.

          SECTION 9.02.  Guaranty Unconditional.  The obligations of each
Guarantor hereunder shall be unconditional, absolute and irrevocable and,
without limiting the generality of the foregoing, shall not be released,
discharged or otherwise affected by:

          (i)  any extension, renewal, settlement, compromise, waiver or release
     in respect of any obligation of any other Obligor under any of the
     Financing Documents, by operation of law or otherwise;

         (ii)  any modification or amendment of or supplement to any of the
     Financing Documents;

        (iii)  any release, non-perfection or invalidity of any direct or
     indirect security for any obligation of any other Obligor under any of the
     Financing Documents;

         (iv)  any change in the corporate existence, structure or ownership of
     any Obligor, or any insolvency, bankruptcy, reorganization or other similar
     proceeding affecting any other Obligor or its assets or any resulting
     release or discharge of any obligation of any other Obligor contained in
     any of the Financing Documents;

          (v)  the existence of any claim, set-off or other rights which any
     Obligor may have at any time against any other Obligor, the Agent, any Bank
     or any other corporation or person, whether in connection with any of the
     Financing Documents or any unrelated transactions, provided that nothing
     herein shall prevent the assertion of any such claim by separate suit or
     compulsory counterclaim;

         (vi)  any invalidity or unenforceability relating to or against any
     other Obligor for any reason of any of the Financing Documents, or any
     provision of applicable law or regulation purporting to prohibit the
     payment by any other Obligor of the principal of or interest on any Note or
     any other amount payable under any of the Financing Documents; or

        (vii)  any other act or omission to act or delay of any kind by any
     Obligor, the Agent, any Bank or any other corporation or person or any
     other circumstance 

                                       50

     whatsoever which might, but for the provisions of this paragraph,
     constitute a legal or equitable discharge of or defense to  either
     Guarantor's obligations hereunder. 
     
          SECTION 9.03.  Discharge Only Upon Payment In Full; Reinstatement In
Certain Circumstances.  Each Guarantor's obligations hereunder shall remain in
full force and effect until the Commitments shall have terminated and the
principal of and interest on the Notes and all other amounts payable by the
Borrower under the Financing Documents shall have been paid in full.  If at any
time any payment of the principal of or interest on any Note or any other amount
payable by the Borrower under the Financing Documents is rescinded or must be
otherwise restored or returned upon the insolvency, bankruptcy or reorganization
of the Borrower or otherwise, each Guarantor's obligations hereunder with
respect to such payment shall be reinstated as though such payment had been due
but not made at such time.

          SECTION 9.04.  Waiver by each of the Guarantors.  Each Guarantor
irrevocably waives acceptance hereof, presentment, demand, protest and any
notice not provided for herein, as well as any requirement that at any time any
action be taken by any corporation or person against any other Obligor or any
other corporation or person.

          SECTION 9.05.  Subrogation.  Each Guarantor irrevocably waives any and
all rights to which it may be entitled, by operation of law or otherwise, upon
making any payment hereunder to be subrogated to the rights of the payee against
the Borrower with respect to such payment or otherwise to be reimbursed,
indemnified or exonerated by the Borrower in respect thereof.

          SECTION 9.06.  Stay of Acceleration.  If acceleration of the time for
payment of any amount payable by the Borrower under any of the Financing
Documents is stayed upon the insolvency, bankruptcy or reorganization of the
Borrower, all such amounts otherwise subject to acceleration under the terms of
this Agreement shall nonetheless be payable by each Guarantor hereunder
forthwith on demand by the Agent made at the request of the requisite proportion
of the Banks specified in Article VI.

          SECTION 9.07.  Limit of Liability.  The obligations of each Guarantor
hereunder shall be limited to an aggregate amount equal to the largest amount
that would not render its obligations hereunder subject to avoidance under any
applicable bankruptcy, insolvency or similar law.

                                 MISCELLANEOUS


          SECTION 10.01.  Notices.  All notices, requests and other
communications to any party hereunder shall be in writing (including bank wire,
telex, facsimile transmission or similar writing) and shall be given to such
party:  (x) in the case of any Obligor or the Agent, at its address, facsimile
number or telex number set forth on the signature pages hereof, (y) in the case
of any Bank, at its address, facsimile number or telex number set forth in its
Administrative Questionnaire or (z) in the case of any party, such other
address, facsimile number or telex number as such party may hereafter specify
for the purpose by notice to the Agent and the Borrower.  Each such notice,
request or other communication shall be effective (i) if given by telex, when
such telex is transmitted to the telex number specified in this Section and the
appropriate answerback is received, (ii) if given by facsimile transmission,
when transmitted to the facsimile number specified in this Section and
confirmation of receipt is received, (iii) if given by mail, 10 days after such
communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iv) if given by any other means, when delivered at
the address specified in this Section; provided that notices to the Agent under
Article II or Article VIII shall not be effective until received.

          SECTION 10.02.  No Waivers.  No failure or delay by the Agent or any
Bank in exercising any right, power or privilege under any Financing Document
shall operate as a waiver thereof nor shall any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power or privilege.  The rights and remedies provided in the
Financing Documents shall be cumulative and not exclusive of any rights or
remedies provided by law.

          SECTION 10.03.  Expenses; Indemnification. (a) The Borrower shall pay
(i) all out-of-pocket expenses of the Agent, including fees and disbursements of
special counsel for the Agent, reasonably incurred in connection with the
preparation of the Financing Documents, any waiver or consent hereunder or
thereunder or any amendment hereof or thereof or any Default or alleged Default
hereunder or thereunder and (ii) if an Event of Default occurs, all out-of-
pocket expenses incurred by the Agent and each Bank, including (without
duplication) the fees and disbursements 

                                       52
<PAGE>
 
of outside counsel and the allocated cost of inside counsel, in connection with
such Event of Default and collection, bankruptcy, insolvency and other
enforcement proceedings resulting therefrom.

          (b)  The Borrower agrees to indemnify the Agent and each Bank, their
respective affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel, which may be reasonably incurred by such Indemnitee in
connection with any investigative, administrative or judicial proceeding
(whether or not such Indemnitee shall be designated a party thereto) brought or
threatened relating to or arising out of the Financing Documents or any actual
or proposed use of proceeds of Loans; provided that no Indemnitee shall have the
right to be indemnified hereunder for such Indemnitee's own gross negligence or
willful misconduct as determined by a court of competent jurisdiction.

          SECTION 10.04.  Sharing of Set-Offs.  Each Bank agrees that if it
shall, by exercising any right of set-off or counterclaim or otherwise, receive
payment of a proportion of the aggregate amount of principal and interest due
with respect to any Note held by it which is greater than the proportion
received by any other Bank in respect of the aggregate amount of principal and
interest due with respect to any Note held by such other Bank, the Bank
receiving such proportionately greater payment shall purchase such
participations in the Notes held by the other Banks, and such other adjustments
shall be made, as may be required so that all such payments of principal and
interest with respect to the Notes held by the Banks shall be shared by the
Banks pro rata; provided that nothing in this Section shall impair the right of
any Bank to exercise any right of set-off or counterclaim it may have and to
apply the amount subject to such exercise to the payment of indebtedness of the
Borrower other than its indebtedness hereunder. Each Obligor agrees, to the
fullest extent it may effectively do so under applicable law, that any holder of
a participation in a Note, whether or not acquired pursuant to the foregoing
arrangements, may exercise rights of set-off or counterclaim and other rights
with respect to such participation as fully as if such holder of a participation
were a direct creditor of such Obligor in the amount of such participation.

          SECTION 10.05.  Amendments and Waivers.  Any provision of this
Agreement or the Notes may be amended or 

                                       53
<PAGE>
 
waived if, but only if, such amendment or waiver is in writing and is signed by
the Obligors and the Required Banks (and, if the rights or duties of the Agent
are affected thereby, by the Agent); provided that no such amendment or waiver
shall, unless signed by all the Banks, (i) increase or decrease the Commitment
of any Bank (except for a ratable decrease in the Commitments of all Banks) or
subject any Bank to any additional obligation, (ii) reduce the principal of or
rate of interest on any Loan or any fees hereunder, (iii) postpone the date
fixed for any payment of principal of or interest on any Loan or any fees
hereunder or for any reduction or termination of any Commitment, (iv) release
the Guarantors hereunder or (v) change the percentage of the Commitments or of
the aggregate unpaid principal amount of the Notes, or the number of Banks,
which shall be required for the Banks or any of them to take any action under
this Section or any other provision of this Agreement.

          SECTION 10.06.  Successors and Assigns.  (a)  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Obligors may not
assign or otherwise transfer any of their rights under this Agreement without
the prior written consent of all Banks.

          (b)  Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Agent, such Bank shall remain responsible for the performance
of its obligations hereunder, and the Borrower and the Agent shall continue to
deal solely and directly with such Bank in connection with such Bank's rights
and obligations under this Agreement. Any agreement pursuant to which any Bank
may grant such a participating interest shall provide that such Bank shall
retain the sole right and responsibility to enforce the obligations of the
Borrower hereunder including, without limitation, the right to approve any
amendment, modification or waiver of any provision of this Agreement; provided
that such participation agreement may provide that such Bank will not agree to
any modification, amendment or waiver of this Agreement described in clause (i),
(ii), (iii), (iv) or (v) of Section 10.05 without the consent of the
Participant. The Borrower agrees that each Participant shall, to the extent
provided in its participation agreement and subject to subsection (e) below, be
entitled to the benefits of Article VIII with respect to its participating
interest. An assignment or other transfer which is not permitted by subsection
(c) or (d) below shall be given effect for

                                      54
<PAGE>
 
purposes of this Agreement only to the extent of a participating interest
granted in accordance with this subsection (b).

          (c)  Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part (equivalent to an
initial Commitment of not less than $5,000,000, unless the Borrower shall
otherwise consent or the assignment is for all of the rights and obligations of
the transferor Bank) of all, of its rights and obligations under this Agreement
and the Notes, and such Assignee shall assume such rights and obligations,
pursuant to an Assignment and Assumption Agreement in substantially the form of
Exhibit I hereto executed by such Assignee and such transferor Bank, with (and
subject to) the subscribed consent of the Borrower, which shall not be
unreasonably withheld, and the Agent; provided that if an Assignee is an
affiliate of such transferor Bank or was a Bank immediately prior to such
assignment, no such consent shall be required; and provided further that such
assignment may, but need not, include rights of the transferor Bank in respect
of outstanding Money Market Loans; and provided further that, unless the
Borrower shall otherwise consent or the assignment is for all of the rights and
obligations of the transferor Bank, the Commitment of such transferor Bank after
giving effect to such assignment (together with the Commitments of its
affiliates) shall not be less than $5,000,000. Upon execution and delivery of
such instrument and payment by such Assignee to such transferor Bank of an
amount equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank with a Commitment as set forth in such
instrument of assumption, and the transferor Bank shall be released from its
obligations hereunder to a corresponding extent, and no further consent or
action by any party shall be required. Upon the consummation of any assignment
pursuant to this subsection (c), the transferor Bank, the Agent and the Borrower
shall make appropriate arrangements so that, if required, a new Note is issued
to the Assignee. In connection with any such assignment, the transferor Bank
shall pay to the Agent an administrative fee for processing such assignment in
the amount of $2,500.

          (d)  Any Bank may at any time assign all or any portion of its rights
under this Agreement and its Note to a Federal Reserve Bank.  No such assignment
shall release the transferor Bank from its obligations hereunder.

          (e)  No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any 

                                      55
<PAGE>
 
greater payment under Section 8.03 or 8.04 than such Bank would have been
entitled to receive with respect to the rights transferred, unless such transfer
is made with the Borrower's prior written consent or by reason of the provisions
of Section 8.02, 8.03 or 8.04 requiring such Bank to designate a different
Applicable Lending Office under certain circumstances or at a time when the
circumstances giving rise to such greater payment did not exist.

          SECTION 10.07.  Collateral.  Each of the Banks represents to the Agent
and each of the other Banks that it in good faith is not relying upon any
"margin stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.

          SECTION 10.08.  Governing Law.  This Agreement and each Note shall be
governed by and construed in accordance with the laws of the State of New York.

          SECTION 10.09.  Counterparts; Integration; Effectiveness.  This
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument. This Agreement constitutes the entire agreement and
understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof. This Agreement shall become effective upon receipt by the Agent of
counterparts hereof signed by each of the parties hereto (or, in the case of any
party as to which an executed counterpart shall not have been received, receipt
by the Agent in form satisfactory to it of telegraphic, telex, facsimile or
other written confirmation from such party of execution of a counterpart hereof
by such party).

          SECTION 10.10.  Judicial Proceedings.  (a)  Consent to Jurisdiction.
Each Obligor irrevocably submits to the jurisdiction of any federal court
sitting in New York City and, in the event that jurisdiction cannot be obtained
or maintained in a federal court, to the jurisdiction of any New York State
court sitting in New York City over any suit, action or proceeding arising out
of or relating to any of the Financing Documents. Each Obligor irrevocably
waives, to the fullest extent permitted by law, any objection which it may now
or hereafter have to the laying of the venue of any such suit, action or
proceeding brought in such court and any claim that any suit, action or
proceeding brought in such a court has been brought in an inconvenient forum.
Each Obligor agrees that a final judgment in any such suit, action or proceeding
brought in such a court shall be

                                      56
<PAGE>
 
conclusive and binding upon it and will be given effect in Bermuda or the Cayman
Islands, as the case may be, to the fullest extent permitted by applicable law
and may be enforced in any federal or New York State court sitting in New York
City (or any other courts to the jurisdiction of which such Obligor is or may be
subject) by a suit upon such judgment, provided that service of process is
effected upon it in one of the manners specified herein or as otherwise
permitted by law.

          (b)  Appointment of Agent for Service of Process.  Each Obligor hereby
irrevocably designates and appoints CT Corporation System having an office on
the date hereof at 1633 Broadway, New York, New York 10019 as its authorized
agent, to accept and acknowledge on its behalf, service of any and all process
which may be served in any suit, action or proceeding of the nature referred to
in subsection (a) above in any federal or New York State court sitting in New
York City. Each Obligor represents and warrants that such agent has agreed in
writing to accept such appointment and that a true copy of such designation and
acceptance has been delivered to the Agent. Said designation and appointment
shall be irrevocable until all principal and interest and all other amounts
payable hereunder and under the Notes shall have been paid in full in accordance
with the provisions hereof and thereof. If such agent shall cease so to act,
each Obligor covenants and agrees to designate irrevocably and appoint without
delay another such agent satisfactory to the Agent and to deliver promptly to
the Agent evidence in writing of such other agent's acceptance of such
appointment.

          (c)  Service of Process.  Each Obligor hereby consents to process
being served in any suit, action or proceeding of the nature referred to in
subsection (a) above in any federal or New York State court sitting in New York
City by service of process upon the agent of such Obligor for service of process
in such jurisdiction appointed as provided in subsection (b) above; provided
that, to the extent lawful and possible, notice of said service upon such agent
shall be mailed by registered or certified air mail, postage prepaid, return
receipt requested, to such Obligor at its address specified on the signature
page hereof or to any other address of which such Obligor shall have given
written notice to the Bank. Each Obligor irrevocably waives, to the fullest
extent permitted by law, all claim of error by reason of any such service in
such manner and agrees that such service shall be deemed in every respect
effective service of process upon such Obligor in any such suit, action or
proceeding and shall, to the fullest extent

                                      57
<PAGE>
 
permitted by law, be taken and held to be valid and personal service upon and
personal delivery to such Obligor.

          (d)  No Limitation on Service or Suit.  Nothing in this Section 10.10
shall affect the right of the Agent or any Bank to serve process in any other
manner permitted by law or limit the right of the Agent or any Bank to bring
proceedings against any Obligor in the courts of any jurisdiction or
jurisdictions.

          SECTION 10.11.  Judgment Currency.  If, under any applicable law and
whether pursuant to a judgment being made or registered against any Obligor or
for any other reason, any payment under or in connection with any of the
Financing Documents is made or satisfied in a currency (the "Other Currency")
other than that in which the relevant payment is due (the "Required Currency")
then, to the extent that the payment (when converted into the Required Currency
at the rate of exchange on the date of payment or, if it is not practicable for
the party entitled thereto (the "Payee") to purchase the Required Currency with
the Other Currency on the date of payment, at the rate of exchange as soon
thereafter as it is practicable for it to do so) actually received by the Payee
falls short of the amount due under the terms of this Agreement and the Notes,
each Obligor shall, to the extent permitted by law, as a separate and
independent obligation, indemnify and hold harmless the Payee against the amount
of such short-fall. For the purpose of this Section, "rate of exchange" means
the rate at which the Payee is able on the relevant date to purchase the
Required Currency with the Other Currency and shall take into account any
premium and other costs of exchange.

          SECTION 10.12.  WAIVER OF JURY TRIAL.  EACH OF THE OBLIGORS, THE AGENT
AND THE BANKS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN
ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE NOTES OR
THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

          SECTION 10.13.  Existing Credit Agreement.  On the Closing Date and
simultaneously with the closing the Borrower hereby gives notice to Morgan
Guaranty Trust Company of New York, as agent, under Section 2.09 of the Credit
Agreement referred to in clause (x) of Section 3.01 of the termination of the
Commitments (as defined therein) and the Banks hereby waive the requirement that
prior notice of such termination be given as therein provided.

                                      58
<PAGE>
 
          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed by their respective authorized officers as of the day and year
first above written.

c/o Morgan Guaranty Trust Company

60 Wall Street
New York, New York 10260-0060

Ladies and Gentlemen:

          We have participated in the preparation of the Credit Agreement (the
"Credit Agreement") dated as of November 15, 1996 among ACE Limited, a Cayman
Islands company limited by shares (the "Borrower"), and A.C.E. Insurance
Company, Ltd., a Bermuda limited liability company ("ACE Insurance"), and
Corporate Officers & Directors Assurance Ltd., a Bermuda limited liability
company ("CODA"), as Guarantors, the Banks listed on the signature pages thereof
(the "Banks") and Morgan Guaranty Trust Company of New York, as Agent, and have
acted as special United States counsel for the Agent for the purpose of
rendering this opinion pursuant to Section 3.01(e) of the Credit Agreement.
Terms defined in the Credit Agreement are used herein as therein defined.

          We have examined originals or copies, certified or otherwise
identified to our satisfaction, of such documents, corporate records,
certificates of public officials and other instruments and have conducted such
other investigations of fact and law as we have deemed necessary or advisable
for purposes of this opinion.

          Upon the basis of the foregoing, we are of the opinion that:

          1.   The execution, delivery and performance by the Borrower of the
Credit Agreement and the Notes are within the Borrower's corporate powers and
have been duly authorized by all necessary corporation action.

          2.   The execution, delivery and performance by each Guarantor of the
Credit Agreement are within such Guarantor's corporate powers and have been duly
authorized by all necessary corporate action.

          3.   The Credit Agreement constitutes a valid and binding agreement of
the Borrower and each Note constitutes a valid and binding obligation of the
Borrower, in each case enforceable in accordance with its terms, except as the
same may be limited by bankruptcy, insolvency or similar laws affecting
creditors' rights generally and by general principles of equity.

          4.   The Credit Agreement constitutes a valid and binding agreement of
each Guarantor enforceable in accordance with its terms, except as the same may
be limited by bankruptcy, insolvency or similar laws affecting creditors' rights
generally and by general principles of equity.

          In giving the foregoing opinion we have relied, with your consent and
without independent investigation, as to all matters governed by the laws of (i)
the Cayman Islands, upon the opinion of Maples and Calder dated the date hereof,
a copy of which has been delivered by you pursuant to Section 3.01(b) of the
Credit Agreement and (ii) Bermuda, upon the opinion of Conyers, Dill & Pearman
dated the date hereof, a copy of which has been delivered to you pursuant to
Section 3.01(c) of the Credit Agreement.

          This opinion is rendered solely to you in connection with the above
matter.  This opinion may not be relied upon by you for any other purpose or
relied upon by any other Person without our prior written consent.

                                            Very truly yours,

accounting determinations hereunder shall be made, and all financial statements
required to be delivered hereunder shall be prepared in accordance with
generally accepted accounting principles as in effect from time to time, applied
on a basis consistent (except for changes concurred in by the Company's
independent public accountants) with the most recent audited consolidated

to the Banks; provided that, if the Company notifies the Agent that the Company
wishes to amend any covenant in Article V to eliminate the effect of any change
in generally accepted accounting principles on the operation of such covenant
(or if the Agent notifies the Company that the Required Banks wish to amend
Article V for such purpose), then the Company's compliance with such covenant
shall be determined on the basis of generally accepted accounting principles in
effect immediately before the relevant change in generally accepted accounting
principles became effective, until either such notice is withdrawn or such
covenant is amended in a manner satisfactory to the Company and the Required
Banks.

                             THE LETTERS OF CREDIT

          SECTION 2.01.  Commitments to Issue Letters of Credit; Extension.
(a)(i)  Subject to the terms and conditions hereof, the Issuing Bank agrees to
issue one or more letters of credit, substantially in the form of Exhibit A
hereto, from time to time upon the request of the Applicant (the "Letters of
Credit"); provided that, immediately after each Letter of Credit is issued, the
aggregate amount of the Letter of Credit Liabilities shall not exceed the Letter
of Credit Commitment.  Upon the date of issuance by the Issuing Bank of a Letter
of Credit, the Issuing Bank shall be deemed, without further action by any party
hereto, to have sold to each Bank, and each Bank shall be deemed, without
further action by any party hereto, to have purchased from the Issuing Bank, a
participation in such Letter of Credit and the related Letter of Credit
Liabilities ratably in accordance with its Participation Percentage.

          (ii) Only one Letter of Credit can be issued hereunder, which must be
issued on or before November 29, 1996, unless such Letter of Credit is extended
as provided in subsection (b) below or this Agreement is amended as provided in
Section 8.05; references herein to Letters of Credit and other similar
references are contained herein only to accommodate the possibility that this
Agreement may be amended to permit the issuance of multiple Letters of Credit.

          (b) (i)  The extension or renewal of any Letter of Credit shall, for
all purposes hereof (other than clause (i) of Section 3.02), be deemed to be an
issuance of such Letter of Credit.  On or before November 10 of each year, the
Issuing Bank shall give notice of termination of each Letter of Credit, unless
(x) it has theretofore timely received Notice of Issuance in respect of the
Letters of Credit, (y) all of the other conditions contained in Section 3.02 are
then satisfied and (z) each Bank party to this Agreement has theretofore agreed
in writing to a one year extension in respect of such Letters of Credit,
confirming the Participation Percentage of such Bank in such Letters of Credit;
provided that no failure by the Issuing Bank to give any such notice of
termination and no delay in giving any such notice shall affect the obligations
of (i) the Company to reimburse the Issuing Bank for any drawing under any
Letters of Credit or (ii) any Banks to pay to the Issuing Bank an amount in
respect of such Bank's ratable share of any such drawing.

                                       8
<PAGE>
 
          (ii) Each Bank party to this Agreement agrees that it will give
notice to the Agent and the Company on or before September 15 of each year as to
whether it agrees to a one year extension of the Letters of Credit, effective
from the next succeeding January 1, provided that the failure of any Bank to
give such notice or any delay in giving the same shall be deemed to be a notice
from such Bank by September 15 that it does not agree to such a one year
extension, and no such Bank shall incur any obligation or liability as a result
of any such failure or delay.

          (iii) If any Bank party to this Agreement gives (or is deemed to have
given) notice that it does not agree to a one year extension as contemplated by
subsection (ii), then the Company may designate by October 20 of such year a
bank or other financial institution which is willing to assume all of the rights
and obligations of such Bank under this Agreement and the other Financing
Documents, such bank or other financial institution to be subject to the written
consent of the Issuing Bank (such consent not to be unreasonably withheld by the
Issuing Bank in its good faith business judgment).  In that case such Bank
agrees to assign such rights and obligations to such designated bank or other
financial institution and enter into an agreement therefor with such other bank
or financial institution pursuant to which such bank or other financial
institution agrees to pay to such Bank all amounts then due and owing (and all
fees accrued to but excluding the date of such agreement) to such Bank hereunder
and under each other Financing Document, in which case such Bank shall no longer
be a party hereto (except as to Sections 2.05, 2.07 and 8.03 for the period
prior to the date of such agreement) and such bank or other financial
institution shall become a Bank party hereto.

          SECTION 2.02.  Notice of Issuance.  (a)  The Applicant shall give the
Issuing Bank notice, by a Letter of Credit Request in the form of Exhibit G
hereto, by November 1 of each year (or, in the case of 1996, by November 22,
1996), specifying the date the applicable Letter of Credit is to be issued or
extended and setting forth the terms of such Letter of Credit which are to be
completed (including, without limitation, the beneficiary thereof, which must be
the Society and Corporation of Lloyd's (such notice, including any such notice
given in connection with the extension of a Letter of Credit, a "Notice of
Issuance").

          (b) Upon receipt of a Notice of Issuance, the Issuing Bank shall
promptly notify each Bank of the contents thereof and of the amount of such
Bank's participation in the applicable Letter of Credit.  The issuance by the
Issuing Bank of each Letter of Credit shall, in addition to

                                       9
<PAGE>
 
the conditions precedent set forth in Article III, be subject to the conditions
precedent that (i) such Letter of Credit shall be substantially in the form of
Exhibit A hereto, or in such other form and contain such terms as shall be
satisfactory to the Company and the Issuing Bank and the Required Banks and (ii)
the Company shall have executed and delivered such other instruments and
agreements relating to such Letter of Credit as the Issuing Bank shall have
reasonably requested.

          SECTION 2.03.  Drawings under Letters of Credit; Reimbursement.  (a)
Upon receipt from the beneficiary of any Letter of Credit of any notice of a
drawing under such Letter of Credit, the Issuing Bank shall promptly notify the
Company and each other Bank as to the amount to be paid as a result of such
drawing and the payment date.  The Company shall be irrevocably and
unconditionally obligated forthwith to reimburse the Issuing Bank for any
amounts paid by the Issuing Bank upon any drawing under any Letter of Credit
(each, a "Reimbursement Obligation"), without presentment, demand, protest or
other formalities of any kind.  All such amounts paid by the Issuing Bank and
remaining unpaid by the Company shall bear interest, payable on demand, for each
day until paid at a rate per annum equal to the sum of the Base Rate plus 2%.

          (b) In addition, each Bank will pay to the Issuing Bank immediately
upon the Issuing Bank's demand at any time during the period commencing after
such drawing until reimbursement therefor in full by the Company, an amount
equal to such Bank's ratable share of such drawing (in proportion to its
participation therein), together with interest on such amount for each day from
the date of the Issuing Bank's demand for such payment (or, if such demand is
made after 12:00 Noon (New York City time) on such date, from the next
succeeding Business Day) to the date of payment by such Bank of such amount at a
rate of interest per annum equal to the Base Rate plus 2%.  Each Bank shall also
be liable for its pro rata share of any amounts paid by the Company that are
subsequently rescinded or avoided, or are otherwise restored or returned.  Such
liability shall be unconditional and without regard to the occurrence of any
Default or the compliance by the Company with any of its obligations under this
Agreement or any other Financing Document.  The Issuing Bank will pay to each
Bank ratably all amounts received from the Company for application in payment of
its reimbursement obligations in respect of any Letter of Credit, but only to
the extent such Bank has made payment to the Issuing Bank in respect of such
Letter of Credit pursuant hereto.

          SECTION 2.04.  Obligations Absolute. The obligations of the Company
and each Bank under Section 2.03 shall be absolute, unconditional and
irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement, under all circumstances whatsoever, including without limitation
the following circumstances:

          (i)  any lack of validity or enforceability of this Agreement or any
     Letter of Credit or any other Financing Document;

          (ii)  any amendment or waiver of or any consent to departure from all
     or any of the provisions of this Agreement or any Letter of Credit or any
     other Financing Document;

          (iii)  the use which may be made of any Letter of Credit by, or any
     acts or omission of, a beneficiary of a Letter of Credit (or any Person for
     whom such beneficiary may be acting);

          (iv)  the existence of any claim, set-off, defense or other rights
     that the Company may have at any time against a beneficiary of a Letter of
     Credit (or any Person for whom such beneficiary may be acting), the Banks
     (including the Issuing Bank) or any other Person, whether in connection
     with this Agreement or any Letter of Credit or any other Financing Document
     or any unrelated transaction;

          (v)  any statement or any other document presented under a Letter of
     Credit proving to be forged, fraudulent or invalid in any respect or any
     statement therein being untrue or inaccurate in any respect whatsoever;

          (vi)  payment under a Letter of Credit against presentation to the
     Issuing Bank of a draft or certificate that does not comply with the terms
     of such Letter of Credit, provided that the Issuing Bank's determination
     that documents presented under such Letter of Credit comply with the terms
     thereof shall not have constituted gross negligence or willful misconduct
     of the Issuing Bank; or

          (vii)  any other act or omission to act or delay of any kind by any
     Bank (including, without limitation, the Issuing Bank), the Agent or any
     other Person or any other event or circumstance whatsoever that might, but
     for the provisions of this clause (vii), constitute a

                                       11
<PAGE>
 
     legal or equitable discharge of the Company's or the Bank's obligations
     hereunder.

          SECTION 2.05.  Indemnification.  (a)  The Company hereby indemnifies
and holds harmless each Bank (including the Issuing Bank) and the Agent from and
against any and all claims, damages, losses, liabilities, costs or expenses
which such Bank or the Agent may incur hereunder or under any other Financing
Document or in connection with any transaction contemplated hereby or thereby
(including, without limitation, any claims, damages, losses, liabilities, costs
or expenses which the Issuing Bank may incur by reason of or in connection with
the failure of any other Bank to fulfill or comply with its obligations to the
Issuing Bank hereunder (but nothing herein contained shall affect any rights the
Company may have against such defaulting Bank)), and none of the Banks
(including the Issuing Bank) nor the Agent nor any of their officers or
directors or employees or agents shall be liable or responsible, by reason of or
in connection with the execution and delivery or transfer of or payment or
failure to pay under any Letter of Credit, including without limitation any of
the circumstances enumerated in Section 2.04, as well as (i) any error,
omission, interruption or delay in transmission or delivery of any message, by
mail, cable, telegraph, telex or otherwise, (ii) any loss or delay in the
transmission of any document required in order to make a drawing under a Letter
of Credit and (iii) any consequences arising from causes beyond the control of
the Issuing Bank, including without limitation any government acts; provided
that the Company shall not be required to indemnify the Issuing Bank for any
claims, damages, losses, liabilities, costs or expenses, and the Company shall
have a claim against the Issuing Bank for direct (but not consequential) damage
suffered by it, to the extent found by a court of competent jurisdiction to have
been caused by (x) the willful misconduct or gross negligence of the Issuing
Bank in determining whether a request presented under any Letter of Credit
complied with the terms of such Letter of Credit or (y) the Issuing Bank's
failure to pay under any Letter of Credit after the presentation to it of a
request strictly complying with the terms and conditions of such Letter of
Credit except as a direct result of court orders prohibiting such payment; and
provided further that the Company shall not be required to indemnify any Bank
(other than the Issuing Bank the indemnification of which under this Section
2.05 is governed by the preceding proviso) or the Agent for any claims, damages,
losses, liabilities, costs or expenses suffered by it to the extent found by a
court of competent jurisdiction to have been caused by its willful misconduct or
gross negligence.  Nothing in this

                                       12
<PAGE>
 
Section 2.05 is intended to limit the obligations of the Company under any other
provision of this Agreement.  To the extent the Company does not indemnify the
Issuing Bank as required by this subsection, the Banks agree to do so ratably in
accordance with their Participation Percentage.

     (b)  The parties hereto agree that in making any payment under any Letter
of Credit by the Issuing Bank none of the following shall constitute or be
deemed to constitute the wilful misconduct or gross negligence of the Issuing
Bank:  (i) the Issuing Bank's exclusive reliance on any document (including
without limitation any draft) presented to it under such Letter of Credit as to
any and all matters set forth therein, including reliance on the amount of any
draft presented thereunder, whether or not the amount due to the beneficiary
thereof equals the amount of such draft, and whether or not any document
presented thereunder proves to be inaccurate or otherwise insufficient in any
respect, if such document on its face appears to be in order and whether or not
such document or any statement contained therein proves to be forged or invalid
or inaccurate or untrue in any respect whatsoever and (ii) any non-material,
non-compliance by the documents (including without limitation any draft)
presented under any Letter of Credit with the terms thereof.

          SECTION 2.06.  Fees.  (a)  Ticking Fee.  On the earlier of the date of
first issuance of a Letter of Credit and January 1, 1997, the Company shall pay
to the Agent, for the account of each Bank (including the Issuing Bank), a
ticking fee with respect to such Letter of Credit on the Letter of Credit
Commitment, at a rate per annum equal to .09 of 1%, calculated on a 360-day
basis, for the period from and including the Effective Date to but excluding

          (b)  Letter of Credit Fee.  The Company agrees to pay to the Agent,

fee with respect to each Letter of Credit, at a rate per annum equals to .15 of
1%, calculated on a 360-day basis, for the period from and including January 1,
1997 to but excluding the Termination Date of such Letter of Credit, on such
Bank's share of the daily average amount available at any time to be drawn under
such Letter of Credit.  The letter of credit fees shall be payable quarterly,
with respect to each Letter of Credit, in arrears on the last Business Day of
each March, June, September and December and on its Termination Date.

          (c)  Fronting Fee.  The Company agrees to pay to the Issuing Bank for
its own account, as compensation for

                                       13
<PAGE>
 
its services hereunder, a fronting fee for each issuance of a Letter of Credit
in the amounts and at the times agreed upon by the Company and the Issuing Bank.

          SECTION 2.07.  Increased Costs; Reduced Return.  (a)  If, on or after
the date of this Agreement, the adoption of any applicable law, rule or
regulation, or any change in any applicable law, rule or regulation, or any
change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Bank with any request or directive
(whether or not having the force of law) of any such authority, central bank or
comparable agency, (i) shall impose, modify or deem applicable any reserve
(including, without limitation, any such requirement imposed by the Board of
Governors of the Federal Reserve System), special deposit, insurance assessment
or similar requirement against letters of credit issued by, or assets of, or
deposits with or for the account of, or credit extended by, any Bank or (ii)
shall impose on any Bank any other condition regarding this Agreement or any
Letter of Credit and the result of any of the foregoing is to increase the cost
to such Bank of issuing or maintaining such Letter of Credit (or its
participation therein), or funding any drawings thereunder, or reduce the amount
of any sum received or receivable by such Bank under this Agreement, by an
amount deemed by such Bank to be material, then, within 45 days after demand by
such Bank (with a copy to the Agent), the Company shall pay to such Bank all
additional amounts which are necessary to compensate such Bank for such
increased cost or reduction.

          (b)  If any Bank shall have determined that, after the date hereof,
the adoption of any applicable law, rule or regulation regarding capital
adequacy, or any change in any applicable law, rule or regulation, or any change
in the interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on capital of such Bank (or any Person controlling such Bank (a "Parent")) as a
consequence of its obligations hereunder or under any Letter of Credit to a
level below that which such Bank (or its Parent) could have achieved but for
such adoption, change, request or directive (taking into consideration its
policies with respect to capital adequacy) by an amount deemed by such Bank to
be material, then from time to time, within 45 days after demand by such Bank,
the Company agrees to pay to such

                                       14
<PAGE>
 
Bank such additional amount or amounts as will compensate such Bank for such
reduction.

          (c)  Each Bank will promptly notify the Company of any event of which
it has knowledge, occurring after the date hereof, which will entitle such Bank
to compensation pursuant to this Section 2.07.  A certificate of any Bank
claiming compensation under this Section 2.07 and setting forth the additional
amount or amounts to be paid to it hereunder shall be conclusive in the absence
of manifest error.  In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

          SECTION 2.08.  Payments and Computations.

(a)  The Company shall make each payment of Reimbursement Obligations, fees,
interest and other amounts payable hereunder to the Agent, as provided herein,
not later than 2:00 P.M. (New York City time) on the day when due in English
Pounds in the case of Reimbursement Obligations or in United States Dollars in
the case of fees, interest or other amounts payable hereunder immediately
available at an address of the Agent specified in writing to the Company by the
Agent.  The Agent will promptly distribute to each Bank its ratable share of
each such payment received by the Agent for the account of such Bank.  Each
payment shall be made without any set-off, counterclaim or deduction.

          (b)  Whenever any payment to be made hereunder shall be stated to be
due on a day which is not a Business Day, such payment shall be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in any computation of interest or fees.

          (c)  In the event that any payment to the Agent hereunder is made
after 2:00 P.M. (London or New York City time, as relevant) on a Business Day,
such payment shall be deemed received on the immediately following Business Day,
and such extension of time shall be included in any computation of interest or
fees.

in equity permitted to be taken by it and (iv) by notice to the Company, require

obligations to deliver Collateral under the Pledge Agreement and its other
obligations under the Financing Documents.

          SECTION 6.02.  Notice of Default.  The Agent shall give notice to the

                                   THE AGENT
                                        
          SECTION 7.01.  Appointment and Authorization.  Each Bank irrevocably
appoints and authorizes the Agent to take such action as agent on its behalf and
to exercise such powers under this Agreement and the other Financing Documents
as are delegated to the Agent by the terms hereof and thereof, together with all
such powers as are reasonably incidental thereto.

          SECTION 7.02.  Agent and Affiliates.  Morgan Guaranty Trust Company of
New York shall have the same rights and powers under this Agreement and each
other Financing Document as any other Bank and may exercise or refrain from
exercising the same as though it were not the Agent, and Morgan Guaranty Trust
Company of New York and its affiliates may accept deposits from, lend money to,
and generally engage in any kind of business with the Company or any affiliate
of the Company as if it were not the Agent hereunder or thereunder.

          SECTION 7.03.  Action by Agent.  The obligations of the Agent under
this Agreement and each other Financing Document are only those expressly set

Agent shall not be required to take any action with respect to any Event of
Default, except as expressly provided in Article VI.

          SECTION 7.04.  Consultation with Experts.  The Agent may consult with
legal counsel (who may be counsel for the Company or the Custodian or both),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken by it in good faith in
accordance with the advice of such counsel, accountants or experts.

          SECTION 7.05.  Liability of Agent.  Neither the Agent nor any of its
affiliates nor any of their respective directors, officers, agents or employees
shall be liable for 

                                       31
<PAGE>
 
any action taken or not taken by it in connection herewith or with any other
Financing Document (i) with the consent or at the request of the Required Banks
or (ii) in the absence of its own gross negligence or willful misconduct.
Neither the Agent nor any of its affiliates nor any of their respective
directors, officers, agents or employees shall be responsible for or have any
duty to ascertain, inquire into or verify (i) any statement, warranty or
representation made hereunder or under any other Financing Document or in
connection herewith or therewith including, without limitation, the authenticity
or accuracy of any draft, certificate, statement or other item presented under a
Letter of Credit, (ii) the performance or observance of any of the covenants or
agreements of the Company; (iii) the satisfaction of any condition specified in
Article III, except receipt of items required to be delivered to the Agent; (iv)
the validity, effectiveness or genuineness of this Agreement or any other
Financing Document or any other instrument or other writing furnished in
connection herewith or therewith; or (v) the existence, validity, enforceability
or priority of the Lien on the Collateral. The Agent shall not incur any
liability by acting in reliance upon any notice, consent, certificate,
statement, or other writing (which may be a bank wire, telex, facsimile
transmission or similar writing) believed by it to be genuine or to be signed by
the proper party or parties.

          SECTION 7.06.  Indemnification.  (a)  Each Bank shall, ratably in
accordance with its Participation Percentage, indemnify the Agent, its
affiliates and their respective directors, officers, agents and employees (to
the extent not reimbursed by the Company) against any cost, expense (including
counsel fees and disbursements), claim, demand, action, loss or liability
(except such as result from any indemnitee's gross negligence or willful
misconduct) that such indemnitees may suffer or incur in connection with this
Agreement or any other Financing Document or any action taken or omitted by such
indemnitees hereunder or thereunder.

          (b)  Without limiting the generality of the foregoing, each Bank
shall, ratably and in accordance with its Participation Percentage, indemnify
the Issuing Bank and its directors, officers, agents and employees (to the
extent not reimbursed by the Company) against any costs, expense (including
counsel fees and disbursements), claim, demand, action, loss or liability that
each such indemnitee may suffer or incur and which results from any failure on
the part of such Bank to pay to the Issuing Bank such Bank's ratable share of
any drawing under any Letter of Credit in accordance with Section 2.03(b).

                                       32

          SECTION 7.07.  Credit Decision.  Each Bank acknowledges that it has,
independently and without reliance upon the Agent or any other Bank, and based
on such documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement.  Each Bank also
acknowledges that it will, independently and without reliance upon the Agent or
any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under this Agreement.

          SECTION 7.08.  Successor Agent.  The Agent may resign at any time by
giving notice thereof to the Banks and the Company.  Upon any such resignation,
the Required Banks shall have the right to appoint a successor Agent, which
successor Agent shall be reasonably acceptable to the Company.  If no successor
Agent shall have been so appointed by the Required Banks, and shall have
accepted such appointment, within 30 days after the retiring Agent gives notice
of resignation, then the retiring Agent may, on behalf of the Banks, appoint a
successor Agent, which shall be a commercial bank organized or licensed under
the laws of the United States of America or of any State thereof and having a
combined capital and surplus of at least $50,000,000.  Upon the acceptance of
its appointment as Agent hereunder by a successor Agent, such successor Agent
shall thereupon succeed to and become vested with all the rights and duties of
the retiring Agent, and the retiring Agent shall be discharged from its duties
and obligations hereunder.  After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent.

                                 MISCELLANEOUS
                                        

          SECTION 8.01.  Notices.  All notices, requests and other
communications to any party hereunder shall be in writing (including bank wire,
telex, facsimile transmission or similar writing) and shall be given to such
party at its address, facsimile number or telex number set forth on the
signature pages hereof or such other address, facsimile number or telex number
as such party may hereafter specify for the purpose by notice to the other
parties hereto.  Each such notice, request or other communication shall be
effective (i) if given by telex, when such telex is 

                                       33
<PAGE>
 
transmitted to the telex number referred to in this Section and the appropriate
answerback is received, (ii) if given by facsimile transmission, when
transmitted to the facsimile number referred to in this Section and confirmation
of receipt is received, (iii) if given by mail, 10 days after such communication
is deposited in the mails with first class postage prepaid, addressed as
aforesaid or (iv) if given by any other means, when delivered at the address
specified in this Section; provided that notices to the Agent under Article II
shall not be effective until received.

          SECTION 8.02.  No Waivers.  No failure or delay by the Agent or any
Bank in exercising any right, power or privilege under this Agreement or any
other Financing Document shall operate as a waiver thereof nor shall any single
or partial exercise thereof preclude any other or further exercise thereof or
the exercise of any other right, power or privilege.  The rights and remedies
provided in this Agreement and the other Financing Documents shall be cumulative
and not exclusive of any rights or remedies provided by law.

          SECTION 8.03.  Expenses; Indemnification. (a) The Company shall pay
(i) all out-of-pocket expenses of the Agent, including fees and disbursements of
special United States counsel for the Agent and any special Bermuda counsel to
the Agent or the Custodian, reasonably incurred in connection with the
preparation of this Agreement and the other Financing Documents, any waiver or
consent hereunder or thereunder or any amendment hereof or thereof or any
Default or alleged Default hereunder or thereunder and (ii) if an Event of
Default occurs, all out-of-pocket expenses incurred by the Agent and each Bank,
including (without duplication) the fees and disbursements of outside counsel
and the allocated cost of inside counsel, in connection with such Event of
Default and collection, bankruptcy, insolvency and other enforcement proceedings
resulting therefrom.

          (b)  The Company agrees to indemnify the Agent and each Bank
(including the Issuing Bank), their respective affiliates and the respective
directors, officers, agents and employees of the foregoing (each an
"Indemnitee") and hold each Indemnitee harmless from and against any and all
liabilities, losses, damages, costs and expenses of any kind, including, without
limitation, the reasonable fees and disbursements of counsel, which may be
reasonably incurred by such Indemnitee in connection with any investigative,
administrative or judicial proceeding (whether or not such Indemnitee shall be
designated a party thereto) brought or threatened relating to or arising out of
the Financing 

                                       34
<PAGE>
 
Documents or any actual or proposed use of proceeds of any draft drawn under any
Letter of Credit; provided that no Indemnitee shall have the right to be
indemnified hereunder for such Indemnitee's own gross negligence or willful
misconduct as determined by a court of competent jurisdiction.

          SECTION 8.04.  Sharing of Set-Offs.  Each Bank agrees that if it
shall, by exercising any right of set-off or counterclaim or otherwise, receive
payment of a proportion of the aggregate amount of any Reimbursement Obligation
owing to it which is greater than the proportion received by any other Bank in
respect of the amount of any Reimbursement Obligation owing to such other Bank,
the Bank receiving such proportionately greater payment shall purchase such
participations in the Reimbursement Obligations owing to the other Banks, and
such other adjustments shall be made, as may be required so that all such
payments with respect to such Reimbursement Obligation owing to the Banks shall
be shared by the Banks pro rata; provided that nothing in this Section shall
impair the right of any Bank to exercise any right of set-off or counterclaim it
may have and to apply the amount subject to such exercise to the payment of
indebtedness of the Company other than its indebtedness hereunder.  The Company
agrees, to the fullest extent it may effectively do so under applicable law,
that any holder of a participation in a Reimbursement Obligation, whether or not
acquired pursuant to the foregoing arrangements or the arrangements set forth in
Section 2.02(a) or otherwise, may exercise rights of set-off or counterclaim and
other rights with respect to such participation as fully as if such holder of a
participation were a direct creditor of the Company in the amount of such
participation.

          SECTION 8.05.  Amendments and Waivers.  Any provision of this
Agreement or the Letters of Credit or any provision of the other Financing
Documents requiring the consent of the Agent and the Required Banks may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by the Company and the Required Banks (and (x) if the rights or duties of
the Agent are affected thereby, by the Agent and (y) if any Letter of Credit is
being amended or waived, by the beneficiary thereof); provided that no such
amendment or waiver shall, unless signed by all the Banks, (i) increase or
decrease the Letter of Credit Commitment or subject any Bank to any additional
obligation, (ii) reduce the amount of any Reimbursement Obligation or the
default rate of interest payable thereon or the amount of any fees or other
amounts payable hereunder, (iii) postpone the date fixed for any payment of 

                                       35
<PAGE>
 
any Reimbursement Obligation or of any interest or fees or other amounts payable
hereunder or postpone the Termination Date of any Letter of Credit, (iv) release
any Collateral furnished pursuant to the Pledge Agreement or otherwise, except
as contemplated by the other Financing Documents or (v) change the Participation
Percentage, or the percentage of the aggregate unpaid principal amount of the
Letter of Credit Liabilities, or the number of Banks, which shall be required
for the Banks or any of them to take any action under this Section or any other
provision of this Agreement or any other Financing Document.

          SECTION 8.06.  Successors and Assigns.  (a)  The provisions of this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns, except that the Company may not
assign or otherwise transfer any of its rights under this Agreement without the
prior written consent of all Banks.

          (b)  Any Bank may at any time grant to one or more banks or other
institutions (each a "Subparticipant") subparticipating interests in its rights
and obligations under this Agreement.  In the event of any such grant by a Bank
of a subparticipating interest to a Subparticipant, whether or not upon notice
to the Company and the Agent, such Bank shall remain responsible for the
performance of its obligations hereunder, and the Company and the Agent shall
continue to deal solely and directly with such Bank in connection with such
Bank's rights and obligations under this Agreement.  Any agreement pursuant to
which any Bank may grant such a subparticipating interest shall provide that
such Bank shall retain the sole right and responsibility to enforce the
obligations of the Company hereunder including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such subparticipation agreement may provide that such
Bank will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii), (iii), (iv) or (v) of Section 8.05 without the
consent of the Subparticipant. The Company agrees that each Subparticipant
shall, to the extent provided in its subparticipation agreement and subject to
subsection (e) below, be entitled to the benefits of Section 2.07 with respect
to its subparticipating interest. An assignment or other transfer which is not
permitted by subsection (c) or (d) below shall be given effect for purposes of
this Agreement only to the extent of a subparticipating interest granted in
accordance with this subsection (b).

                                       36
<PAGE>
 
          (c)  Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part (in an amount not
less than (Pounds)10,000,000 unless the Company shall otherwise consent) of all,
of its rights and obligations under this Agreement and the other Financing
Documents, and such Assignee shall assume such rights and obligations with (and
subject to) the subscribed consent of the Company, which shall not be
unreasonably withheld, and the Issuing Bank, which may consent or not in its
sole discretion; provided that if an Assignee is an affiliate of such transferor
Bank or was a Bank immediately prior to such assignment, no such consent of the
Company shall be required.  Upon the consummation of any assignment pursuant to
this subsection (c) and payment by such Assignee to such transferor Bank of an
amount equal to the purchase price agreed between such transferor Bank and such
Assignee, such Assignee shall be a Bank party to this Agreement and shall have
all the rights and obligations of a Bank as set forth in any instrument of
assumption, and the transferor Bank shall be released from its obligations
hereunder to a corresponding extent, and no further consent or action by any
party shall be required.  In connection with any such assignment, the transferor
Bank shall pay to the Agent an administrative fee for processing such assignment
in the amount of $2,500.

          (d)  Any Bank may at any time assign all or any portion of its rights
under this Agreement and the other Financing Documents to a Federal Reserve
Bank.  No such assignment shall release the transferor Bank from its obligations
hereunder.

          (e)  No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Sections 2.07 and 8.13
than such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Company's prior written
consent or at a time when the circumstances giving rise to such greater payment
did not exist.

          SECTION 8.07.  Collateral.  Each of the Banks represents to the Agent
and each of the other Banks that it in good faith is not relying upon any
"margin stock" (as defined in Regulation U) as collateral in the extension or
maintenance of the credit provided for in this Agreement.

          SECTION 8.08.  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

                                       37
<PAGE>
 
          SECTION 8.09.  Counterparts; Integration; Effectiveness.  This
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument.  This Agreement, together with the other Financing
Documents, constitutes the entire agreement and understanding among the parties
hereto and supersedes any and all prior agreements and understandings, oral or
written, relating to the subject matter hereof.  This Agreement shall become
effective upon receipt by the Agent of counterparts hereof signed by each of the
parties hereto (or, in the case of any party as to which an executed counterpart
shall not have been received, receipt by the Agent in form satisfactory to it of
telegraphic, telex, facsimile or other written confirmation from such party of
execution of a counterpart hereof by such party).

          SECTION 8.10.  Judicial Proceedings.  (a)  Consent to Jurisdiction.
The Company irrevocably submits to the jurisdiction of any federal court sitting
in New York City, and in the event that jurisdiction cannot be obtained or
maintained in a federal court, to the jurisdiction of any New York State court
sitting in New York City over any suit, action or proceeding arising out of or
relating to this Agreement or any other Financing Document.  The Company
irrevocably waives, to the fullest extent permitted by law, any objection which
it may now or hereafter have to the laying of the venue of any such suit, action
or proceeding brought in such court and any claim that any suit, action or
proceeding brought in such a court has been brought in an inconvenient forum.
The Company agrees that a final judgment in any such suit, action or proceeding
brought in such a court shall be conclusive and binding upon it and will be
given effect in Bermuda to the fullest extent permitted by applicable law and
may be enforced in any federal or New York State court sitting in New York City
(or any other court to the jurisdiction of which the Company is or may be
subject) by a suit upon such judgment, provided that service of process is
effected upon it in one of the manners specified herein or as otherwise
permitted by law.

          (b)  Appointment of Agent for Service of Process.  The Company hereby
irrevocably designates and appoints CT Corporation System having an office on
the date hereof at 1633 Broadway, New York, New York 10019 as its authorized
agent, to accept and acknowledge on its behalf, service of any and all process
which may be served in any suit, action or proceeding of the nature referred to
in subsection (a) above in any federal or New York State court sitting in New
York City.  The Company represents and warrants that such agent has agreed in
writing to accept such appointment and 

                                       38
<PAGE>
 
that a true copy of such designation and acceptance has been delivered to the
Agent. Said designation and appointment shall be irrevocable until each
Reimbursement Obligation and each other amount payable hereunder shall have been
paid in full in accordance with the provisions hereof. If such agent shall cease
so to act, the Company covenants and agrees to designate irrevocably and appoint
without delay another such agent satisfactory to the Agent and to deliver
promptly to the Agent evidence in writing of such other agent's acceptance of
such appointment.

          (c)  Service of Process.  The Company hereby consents to process being
served in any suit, action or proceeding of the nature referred to in subsection
(a) above in any federal or New York State court sitting in New York City by
service of process upon the agent of the Company for service of process
appointed as provided in subsection (b) above; provided that, to the extent
lawful and possible, notice of said service upon such agent shall be mailed by
registered or certified air mail, postage prepaid, return receipt requested, to
the Company at its address specified on the signature page hereof or to any
other address of which the Company shall have given written notice to the Agent.
The Company irrevocably waives, to the fullest extent permitted by law, all
claims of error by reason of any such service in such manner and agrees that
such service shall be deemed in every respect effective service of process upon
the Company in any such suit, action or proceeding and shall, to the fullest
extent permitted by law, be taken and held to be valid and personal service upon
and personal delivery to the Company.

          (d)  No Limitation on Service or Suit.  Nothing in this Section 8.10
shall affect the right of the Agent or any Bank to serve process in any other
manner permitted by law or limit the right of the Agent or any Bank to bring
proceedings against the Company in the courts of any jurisdiction or
jurisdictions.

          SECTION 8.11.  Judgment Currency.  If, under any applicable law and
whether pursuant to a judgment being made or registered against the Company or
for any other reason, any payment under or in connection with this Agreement or
any other Financing Document is made or satisfied in a currency (the "Other
Currency") other than that in which the relevant payment is due (the "Required
Currency"), then, to the extent that the payment (when converted into the
Required Currency at the rate of exchange on the date of payment or, if it is
not practicable for the party entitled thereto (the "Payee") to purchase the
Required Currency with the Other Currency on the date of payment, at the rate of

                                       39
<PAGE>
 
exchange as soon thereafter as it is practicable for it to do so) actually
received by the Payee falls short of the amount due under the terms of this
Agreement, the Company shall, to the extent permitted by law, as a separate and
independent obligation, indemnify and hold harmless the Payee against the amount
of such short-fall.  For the purpose of this Section, "rate of exchange" means
the rate at which the Payee is able on the relevant date to purchase the
Required Currency with the Other Currency and shall take into account any
premium and other costs of exchange.

          SECTION 8.12.  WAIVER OF JURY TRIAL.  THE COMPANY, THE AGENT AND THE
BANKS HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL
PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE OTHER FINANCING
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

          SECTION 8.13.  Taxes.  (a)  For purposes of this Section 8.13, the 
following terms have the following meanings:

          "Taxes" means any and all present or future taxes, duties, levies,
imposts, deductions, charges or withholdings of any nature with respect to any
payment by the Company pursuant to this Agreement or under any Financing
Documents, and all liabilities with respect thereto, excluding in the case of
each Bank and the Agent, taxes imposed on its net income, and franchise or
similar taxes imposed on it, by a jurisdiction under the laws of which such Bank
or the Agent (as the case may be) is organized or in which its principal
executive office is located (all such excluded taxes being hereinafter referred
to as "Domestic Taxes").

          "Other Taxes" means any present or future stamp or documentary taxes
and any other excise or property taxes, or similar charges or levies, which
arise from any payment made pursuant to this Agreement or under any Financing
Documents or from the execution, delivery, registration or enforcement of, or
otherwise with respect to, this Agreement or any Financing Documents.

          (b) Any and all payments by the Company to or for the account of any
Bank or the Agent hereunder or under any Financing Documents shall be made
without deduction for any Taxes or Other Taxes; provided that, if the Company
shall be required by law to deduct any Taxes or Other Taxes from any such
payments, (i) the sum payable shall be increased as necessary so that after
making all required deductions and withholdings (including deductions or
withholdings applicable to additional sums payable under this Section 

                                       40
<PAGE>
 
8.13) such Bank or the Agent (as the case may be) receives an amount equal to
the sum it would have received had no such deductions been made, (ii) the
Company shall make such deductions or withholdings, (iii) the Company shall pay
the full amount deducted or withheld to the relevant taxation authority or other
authority in accordance with applicable law and (iv) the Company shall furnish
to the Agent, at its address referred to in Section 8.01, the original or a
certified copy of a receipt evidencing payment thereof.

          (c)  The Company agrees to indemnify each Bank and the Agent for the
full amount of Taxes or Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section 8.13), whether or not legally or correctly imposed, paid by such
Bank or the Agent (as the case may be) in good faith and any liability
(including penalties, interest and expenses) arising therefrom or with respect
thereto.  In addition, the Company agrees to indemnify each Bank and the Agent
for all Domestic Taxes (calculated based on a hypothetical basis at the maximum
marginal rate for a corporation) and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto to the extent
such Domestic Taxes result from the payment of or indemnification for Taxes,
Other Taxes or Domestic Taxes pursuant to this Section 8.13.  This
indemnification shall be paid within 15 days after such Bank or the Agent (as
the case may be) makes demand therefor.

          (d)  Each Bank and the Agent shall, at the request of the Company, use
reasonable efforts (consistent with applicable legal and regulatory
restrictions) to file any certificate or document requested by the Company if
the making of such a filing would avoid the need for or reduce the amounts
payable to or for the account of such Bank or the Agent (as the case may be)
pursuant to this Section 8.13 which may thereafter accrue and would not, in the
sole judgment of such Bank or the Agent, require such Bank or the Agent to
disclose any confidential or proprietary information or be otherwise
disadvantageous to such Bank or the Agent.

          (e)  Notwithstanding the foregoing, nothing in this Section 8.13 shall
interfere with the rights of any Bank or the Agent, as the case may be, to
conduct its fiscal or tax affairs in such manner as it deems fit.

          SECTION 8.14.  Confidential Information.  Each Bank agrees to comply
with the terms of Section 21 of the Pledge Agreement as if such terms were
expressly applicable to each Bank and each Bank agrees to notify its auditors
and attorneys of the provisions of Section 21 of the Pledge Agreement prior to

                                       41
<PAGE>
 
providing them with any Confidential Information (as defined therein) and
instruct them to comply with the terms of such Section as if such terms were
expressly applicable to such auditors and attorneys.

                                       42

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed by their respective authorized officers as of the day and year
first above written.

                                PLEDGE AGREEMENT
                                ----------------

     PLEDGE AGREEMENT dated as of November 22, 1996 between A.C.E. INSURANCE
COMPANY, LTD., a company incorporated in and under the laws of Bermuda whose
registered office is at The ACE Building, Woodbourne Avenue, Pembroke, Bermuda
(hereinafter called the "Pledgor") of the first part, and MORGAN GUARANTY TRUST
COMPANY OF NEW YORK, as Issuing Bank (the "Issuing Bank") and as Agent (the
"Bank") for the Participating Banks (as defined below) of the second part.

     WHEREAS, as contemplated by the Reimbursement Agreement (the "Reimbursement
Agreement") dated as of November 22, 1996 among the Pledgor, the Banks listed
therein (the "Participating Banks", including Morgan Guaranty Trust Company of
New York) and Morgan Guaranty Trust Company of New York, as Issuing Bank and
Agent, the Pledgor has requested that the Issuing Bank from time to time issue
letters of credit for the Pledgor's account, the reimbursement of which and all
other payments related thereto will be secured by the Collateral (as defined
below); and

     WHEREAS, the Issuing Bank has agreed to issue such letters of credit
subject to the terms and conditions hereinafter set forth and as set forth in
the Reimbursement Agreement, including without limitation, the automatic
participation of the Participating Banks therein;

     NOW, THEREFORE, the parties hereto agree as follows:

     1.   As inducement for, and in consideration of, inter alia, (i) the
Issuing Bank issuing letters of credit for the Pledgor's account from time to
time (each a "Letter of Credit" and, together, the "Letters of Credit") pursuant
to the Reimbursement Agreement (each defined term used herein, but not otherwise
defined herein, shall have the meaning ascribed to it therein) and (ii) the
participation by the Participating Banks therein, in each case the receipt and
adequacy of which are hereby acknowledged, the Pledgor hereby pledges and
assigns to the Bank and grants to the Bank a security interest and a charge in
the Collateral pursuant to this Agreement as security for all amounts owed from
time to time to the Issuing Bank, the Participating Banks and the Agent by the
Pledgor under the Financing Documents (collectively, the "Secured Obligations").
For purposes hereof, the term "Bank" shall mean Morgan Guaranty Trust Company of
New

                                       54
<PAGE>
 
York in its capacity as agent for the Participating Banks hereunder.

     2.  (a) As stated above, as collateral security for the performance of the
Secured Obligations, the Pledgor hereby pledges and assigns to the Bank, and
grants to the Bank a security interest and a charge in, all Eligible Securities
(as defined below) and cash held in the Pledge Account (as defined in the
Custodian Agreement dated as of November 19, 1996 between The Bank of Bermuda
Limited (the "Custodian") and the Pledgor (the "Custodian Agreement")), as set
forth in a written addendum hereto signed by the Pledgor and the Bank, which may
be amended from time to time by the Pledgor and the Bank, along with all
proceeds and products thereof, accessions thereto and substitutions therefor and
any other property of the Pledgor held by the Bank or the Custodian expressly
for this purpose (the "Collateral"). The Pledgor covenants to deliver to the
Custodian, on or before December 31, 1996, Eligible Securities the Value (as
defined below) of which shall equal the Minimum Collateral Amount (as defined
below). For purposes hereof, the term "Eligible Securities" shall mean "direct
claims (including securities, loans, and leases) on, and the portions of claims
that are directly and unconditionally guaranteed by, the central governments of
the OECD countries and U.S. Government agencies", as used in Appendix A, Section
III(C), Category I to Regulation H, as promulgated by the Board of Governors of
the Federal Reserve System, but only so long as no risk weight is attached
thereto and the same are either (i) uncertificated and governed by the
provisions of 31 C.F.R. Part 306 and, after January 1, 1997, 31 C.F.R. Part 357
or such similar provisions of the Code of Federal Regulations, applicable to
United States agency securities as are acceptable to the Bank or (ii)
certificated. So long as no Default has occurred and is continuing, the Pledgor
may from time to time withdraw portions of the Collateral and substitute other
Eligible Securities and/or cash therefor, which substituted property shall then
be deemed to constitute a portion of the Collateral, provided that at no time
shall the Value of the Collateral in the Pledge Account following any such
withdrawal be less than the Minimum Collateral Amount. For purposes of this
Agreement, the "Value" of an Eligible Security shall be the fair market value
thereof as determined by the Custodian.

     (b)  The Pledgor agrees that, if on the 15th Business Day of any calendar
month (commencing with January, 1997) or at other times as notified by the Bank,
the Value of the Collateral is less than an amount equal to 115% (the "Minimum
Collateral Amount") of the then existing Letter of Credit Liabilities, the
Pledgor shall deposit with the Custodian such additional Eligible Securities
and/or cash as is necessary so that the Value of the Collateral is equal to or
exceeds the Minimum Collateral Amount. If the Pledgor does not deposit such
additional Collateral within five Business Days after receiving a notice from
the

                                       55
<PAGE>
 
Bank stating that the Value of the Collateral has become less than the Minimum
Collateral Amount, the Pledgor agrees that the Bank may sell the Collateral and
retain the proceeds as security for the performance of the Secured Obligations.

     (c)  The Pledgor shall forthwith upon the execution and delivery of this
Agreement register this Agreement and each other Financing Document which
creates a charge, lien or security interest in the Register of Charges with the
Registrar of Companies in Bermuda in accordance with Section 55 of the Companies
Act 1981, as amended, and pay the registration fee applicable thereon.

     (d)  (i) The Pledgor will faithfully preserve and protect the Bank's
security interest and charge in the Collateral and will do all such acts and
things and execute and deliver all such documents and instruments, including
without limitation, the execution and delivery of a Notice of Pledge in the form
of Exhibit A hereto (the "Notice of Pledge"), along with such further pledges,
assignments, financing statements and continuation statements, as the Bank in
its reasonable discretion may deem necessary or advisable from time to time in
order to preserve, protect and perfect such pledge and assignment and security
interest and charge and the priority thereof. The Pledgor hereby authorizes the
Bank to sign and file financing statements and continuation statements without
the signature of the Pledgor. The Bank shall promptly furnish copies of any such
financing statements and continuation statements to the Pledgor.

          (ii) The Pledgor will not permit any liens, security interests,
charges or adverse claims (other than in favor of the Bank) to exist upon any of
the Collateral except for the interest of the Custodian arising under the
Custodian Agreement.

     3.   The Pledgor represents and warrants:

     (a)  that it is a company duly organized and is empowered under its
memorandum of association and by-laws to enter into and perform this Agreement,
the Notice of Pledge and the Custodian Agreement and any other documents related
hereto or thereto and has taken all necessary actions to authorize the
execution, delivery and performance of this Agreement, the Notice of Pledge and
the Custodian Agreement and any other documents related hereto or thereto;      

     (b)  (i) that, upon delivery of the Collateral to the Custodian and the
crediting thereof to the Pledge Account, all of the Collateral will be validly
and duly pledged and assigned to the Bank and that a security interest or charge
therein will exist in favor of the Bank in accordance with law, and agrees to
defend the Bank's right, title, lien, charge and security interest in and to the
Collateral against the claims and

                                       56
<PAGE>
 
demands of all Persons whomsoever and (ii) that upon such delivery and
crediting, the Bank will have a valid security interest and charge in the
Collateral, free and clear of all claims, mortgages, pledges, assignments,
liens, encumbrances, charges and security interests of every nature whatsoever
except for the interest of the Custodian arising under the Custodian Agreement;

     (c)  that no consent or approval by, and no notice to or filing with, any
governmental or regulatory authority or other Person is required for the due and
valid execution, delivery and performance of this Agreement, the Notice of
Pledge and the Custodian Agreement by the Pledgor or to establish or maintain
this pledge and assignment as a first priority pledge of the Collateral, other
than the registration of this Agreement in the Register of Charges in accordance
with Section 55 of the Companies Act 1981, as amended and such other consent,
approval, notice and filing as has been obtained; and

     (d)  that none of the execution, delivery or performance of this Agreement,
the Notice of Pledge or the Custodian Agreement, nor the registration of this
Agreement or any other Financing Document which creates a charge, lien or
security interest, will be subject to ad valorem stamp duty in Bermuda.

     4.   Dividends (other than liquidating dividends), distributions and
interest declared, made or paid upon any of the Collateral shall be credited to
the account of the Pledgor until the Bank notifies the Custodian in writing that
a Default has occurred and is continuing.

     5.   If any of the Secured Obligations shall not be performed as and when
due pursuant to the Reimbursement Agreement, the Bank may cause all or any part
of the Collateral to be transferred to or registered in its name, as agent for
the Participating Banks, or the name of its nominee or nominees. The Bank shall
promptly notify the Pledgor of any such action it shall have taken, provided
that the failure to do so shall not affect the validity of such action. If any
of the Secured Obligations shall not be performed as and when due pursuant to
the Reimbursement Agreement, upon notice to the Custodian, the Bank shall be
entitled to exercise all voting power with respect to the Collateral.

     6.   If any of the Secured Obligations shall not be performed as and when
due pursuant to the Reimbursement Agreement, the Bank, without obligation to
resort to other security, shall have the right at any time and from time to time
to sell, resell, assign and deliver, in its discretion, all or any of the
Collateral, in one or more parcels at the same or different times, and all
right, title and interest, claim and demand therein and right of redemption
thereof, on any securities exchange on which the Collateral or any of it may be
listed, or at public


                                       57

<PAGE>
 
or private sale, for cash, upon credit or for future delivery, and in connection
therewith the Bank may grant options, the Pledgor hereby waiving and releasing
any and all equity or right of redemption. If any of the Collateral is sold by
the Bank upon credit or for future delivery, the Bank and the Participating
Banks shall not be liable for the failure of the purchaser to purchase or pay
for the same and, in the event of any such failure, the Bank may resell such
Collateral. In no event shall the Pledgor be credited with any part of the
proceeds of sale of any Collateral until cash payment thereof has actually been
received by the Bank.

     7.   No demand, advertisement or notice, all of which are hereby expressly
waived, shall be required in connection with any sale or other disposition of
any part of the Collateral which threatens to decline speedily in value or which
is of a type customarily sold on a recognized market; otherwise the Bank shall
give the Pledgor at least five Business Days' prior notice of the time and place
of any public sale and of the time after which any private sale or other
disposition is to be made, which notice the Pledgor agrees is reasonable, all
other demands, advertisements and notices being hereby waived. The Bank shall
not be obligated to make any sale of Collateral if it shall determine not to do
so, regardless of the fact that notice of sale may have been given. The Bank
may, without notice or publication, adjourn any public or private sale or cause
the same to be adjourned from time to time by announcement at the time and place
fixed for sale, and such sale may, without further notice, be made at the time
and place to which the same was so adjourned. In the case of all sales of
Collateral, public or private, the Pledgor shall pay all reasonable costs and
expenses of every kind for sale or delivery, including brokers' and attorneys'
fees, and after deducting such costs and expenses from the proceeds of sale, the
Bank shall apply any residue to the payment of the Secured Obligations as
follows: first, to the payment to the Agent of any other costs or expenses
incurred by it under the Financing Documents, second, to the payment of all
default interest on the Reimbursement Obligations, third to the reimbursement of
all Reimbursement Obligations and fourth to the payment of any other amounts
then due and payable to the Bank, the Participating Banks or the Agent under the
Financing Documents. The balance, if any, remaining after payment in full of all
such amounts and the termination of the Letters of Credit and the Reimbursement
Agreement shall be paid to the Pledgor, subject to any duty of the Bank imposed
by law to the holder of any subordinate security interest or charge in the
Collateral known to the Bank.

     8.   The Pledgor recognizes that the Bank may be unable to effect a public
sale of all or a part of the Collateral by reason of, among other things,
certain prohibitions contained in United States securities laws or the
securities laws of the various States of the United States, as now or hereafter
in effect, but may be compelled to resort to one or more private sales to a
restricted group of


                                       58

<PAGE>
 
purchasers who will be obliged to agree, among other things, to acquire such
Collateral for their own account, for investment and not with a view to the
distribution or resale thereof. The Pledgor agrees that private sales so made
may be at prices and other terms less favorable to the seller than if such
Collateral were sold at public sales, and that the Bank has no obligation to
delay sale of any such Collateral for the period of time necessary to permit
such Collateral to be sold at public sale. The Pledgor agrees that private sales
made under the foregoing circumstances shall be deemed to have been made in a
commercially reasonable manner.

     9.   The remedies provided herein in favor of the Bank shall not be deemed
exclusive, but shall be cumulative, and shall be in addition to all other
remedies in favor of the Bank existing at law or in equity.

     10.  The Bank shall have the right, for and in the name, place and stead of
the Pledgor, to execute endorsements, assignments or other instruments of
conveyance or transfer with respect to all or any of the Collateral.

     11.  The Bank shall have no duty as to the collection or protection of the
Collateral or any income thereon or as to the preservation of any rights
pertaining thereto, beyond the safe custody of any thereof actually in its own
physical possession. With respect to any maturities, calls, conversions,
exchanges, redemptions, offers, tenders or similar matters relating to any of
the Collateral (herein called "events"), the Bank's duty shall be fully
satisfied if (a) the Bank exercises reasonable care to ascertain the occurrence
and to give reasonable notice to the Pledgor of any events applicable to any
Collateral which is registered and held in the name of the Bank or its nominee,
(b) the Bank gives the Pledgor reasonable notice of the occurrence of any
events, of which the Bank has received actual knowledge, as to any Collateral
which is in bearer form or is not registered and held in the name of the Bank or
its nominee or the Custodian or its nominee (the Pledgor agreeing to give the
Bank reasonable notice of the occurrence of any events applicable to any
Collateral of which the Pledgor has received knowledge), and (c) in the exercise
of its sole discretion (i) the Bank endeavors to take such action with respect
to any of the events as the Pledgor may reasonably and specifically request in
writing in sufficient time for such action to be evaluated and taken as long as
after the taking of any such action, the Value of the Collateral is not less
than the Minimum Collateral Amount or (ii) if the Bank determines that the
action requested might adversely affect the value of the Collateral as
collateral, the collection of the Secured Obligations, or otherwise prejudice
the interests of the Bank, the Bank gives reasonable notice to the Pledgor that
any such requested action will not be taken and if the Bank makes such
determination or if the Pledgor fails to make such timely request, the Bank


                                       59

<PAGE>

may take such other action as it deems reasonably advisable in the
circumstances. Except as hereinabove specifically set forth, the Bank shall have
no further obligation to ascertain the occurrence of, or to notify the Pledgor
with respect to, any events and shall not be deemed to assume any such further
obligation as a result of the establishment by the Bank of any internal
procedures with respect to any Collateral. The Pledgor releases the Bank from
any claims, causes of action and demands that do not arise as a result of the
negligence or willful misconduct of the Bank at any time arising out of or with
respect to this Agreement or any other Financing Document or the Collateral
and/or any actions, taken or omitted to be taken by the Bank with respect hereto
or thereto, and the Pledgor hereby agrees to hold the Bank harmless from and
with respect to any and all such claims, causes of action and demands of other
Persons.

     12.  The Pledgor hereby irrevocably appoints the Bank as the Pledgor's
attorney-in-fact for the purpose of carrying out the provisions of this
Agreement and the Notice of Pledge and taking any action and executing any
instrument which either may deem necessary or advisable to accomplish the
purposes hereof or thereof. Without limiting the generality of the foregoing,
the Bank shall have the right and power to receive, endorse and collect all
checks and other orders for the payment of money made payable to the Pledgor
representing any interest or dividend or other distribution payable in respect
of the Collateral or any part thereof and to give full discharge for the same.

     13.  No delay on the part of the Bank in exercising any of its options,
powers or rights, or partial or single exercise thereof, shall constitute a
waiver thereof.

     14.  Upon the repayment in full of all Secured Obligations and the
termination of the Letters of Credit and all other Financing Documents except
the Custodian Agreement, the Pledgor shall be entitled to the return of all of
the Collateral and of all other property and cash which has not been used or
applied toward the payment thereof. The assignment by the Bank to the Pledgor of
such Collateral and other property shall be without representation or warranty
of any nature whatsoever and wholly without recourse.

     15.  Any notice or demand upon the Pledgor shall be deemed to have been
sufficiently given for all purposes thereof if sent by overnight courier or by
telecopy, with receipt acknowledged, to the Pledgor at the address specified
below, or at such other address as the Pledgor may theretofore have designated
in writing and given in like manner to the Bank.


                                       60

<PAGE>

     16.  Any waiver, permit, consent or approval of any kind or character on
the part of the Bank of any breach or default under this Agreement or any such
waiver of any provision or condition of this Agreement must be in writing and
shall be effective only to the extent specifically set forth in such writing.
Each of the provisions contained in this Agreement shall be severable and
distinct from one another and if at any time one or more of such provisions is
or becomes invalid, illegal or unenforceable, the validity, legality, and
enforceability of each of the remaining provisions of this Agreement shall not
in any way be affected, prejudiced or impaired thereby.

     17.  This Agreement and the rights and obligations of the Bank and the
Pledgor hereunder shall be construed in accordance with and governed by the laws
of New York, cannot be changed orally and shall bind and inure to the benefit of
the Pledgor and the Bank and their respective successors and permitted assigns.

     18.  This Agreement may be executed in counterparts, each of which shall be
deemed an original and all of which taken together shall constitute but one and
the same instrument.

     19.  This Agreement is in addition to and not in limitation of any other
agreement between the parties. In the event of any conflict between the
provisions of this Agreement and those of any other such agreement, the
provisions of this Agreement shall prevail.

     20.  The Pledgor agrees to pay the Bank on demand all reasonable costs,
including legal fees, incurred by the Bank in connection with the administration
and enforcement of this Agreement.

     21.  The Bank shall not, unless compelled to do so by any court of
competent jurisdiction or regulatory authority, or unless in response to a
request from Bank regulators, disclose to any Person (other than the
Participating Banks and their auditors and attorneys, who shall be subject to
the terms of Section 8.14 of the Reimbursement Agreement) not expressly
authorized in writing by the Pledgor or pursuant to the terms hereof any non-
public information relating to the Pledgor and to the affairs of the Pledgor of
which the Bank shall have become possessed during the period of this Agreement
(the "Confidential Information"). Without limiting the generality of the
foregoing, the existence of this Agreement and the other Financing Documents,
the relationship hereunder between the Pledgor and the Bank, the nature, value
and the location of any assets of the Pledgor (including without limitation, the
Collateral), and the identity of the Pledgor are to be regarded by the Bank as
Confidential Information which the


                                       61

<PAGE>

Bank and persons under its control may not disclose except in accordance with
the terms of this Section 21. In any such event the Bank will furnish a copy of
this Section to any Person (other than the Participating Banks and their
auditors and attorneys) to whom the Bank is required to make such disclosure
and, if permitted to do so by law, the Bank will advise the Pledgor prior to
making such disclosures. Notwithstanding the foregoing, Confidential Information
shall not include information that is or becomes publicly available, information
that was available to the Bank prior to its disclosure hereunder and information
which becomes available to the Bank on a non-confidential basis from a source
that is not, to the Bank's knowledge, subject to a confidentiality agreement
with the Pledgor.

     If an attempt is made through a subpoena, attachment, execution, levy or
other legal proceeding to obtain Confidential Information, the Bank shall, if
permitted to do so by law, immediately notify the Pledgor so that the Pledgor
may attempt to resist such disclosure.



                                       62

<PAGE>
 
     IN WITNESS WHEREOF, the Pledgor and the Bank have caused this Agreement to
be duly executed by their respective officers duly authorized as of the day and
year first above written.

Hamilton, Bermuda

                                NOTICE OF PLEDGE
                                ----------------

     Re:  Pledge and assignment to Morgan Guaranty Trust Company of New York, as
          agent, of Securities Owned by A.C.E. Insurance Company, Ltd. and Held
          by The Bank of Bermuda Limited, as Custodian

Dear Sirs:

     This letter is to notify The Bank of Bermuda Limited (the "Custodian") that
A.C.E. Insurance Company, Ltd. (the "Pledgor") has agreed from time to time to
pledge and assign certain securities and the proceeds thereof (including cash)
(the "Eligible Securities") owned by it and specified in the Pledge Agreement
(as hereinafter defined) to Morgan Guaranty Trust Company of New York, as agent
(the "Bank"), pursuant to and on the terms and conditions set forth in the
Pledge Agreement dated as of November 22, 1996 (the "Pledge Agreement"), a copy
of an executed copy of which is attached hereto, to secure certain obligations
incurred by the Pledgor to the Bank and (as defined therein) the Participating
Banks and the Agent. The Pledgor unconditionally agrees to indemnify and hold
the Custodian harmless against all loss or damages (including reasonable legal
fees) that the Custodian may suffer as a result of or in connection with such
pledge and assignment or the performance of its obligations under this Agreement
or the Confirmation and Agreement attached as Exhibit B to the Pledge Agreement
(the "Confirmation and Agreement") which are not suffered as a result of the
negligence or willful misconduct of the Custodian or that of its officers,
employees or agents.

     The Custodian is hereby irrevocably authorized and directed to do the
following: (i) hold the Eligible Securities as the agent of and subject to the
sole written order or instructions of the Bank in accordance with the Pledge
Agreement in the Pledge Account

                                       64
<PAGE>
 
(as defined in the Custodian Agreement dated November 19, 1996 (the "Custodian
Agreement") between the Pledgor and the Custodian), following deposit of the
Eligible Securities in the Pledge Account by the Pledgor; (ii) make appropriate
entries on its books to evidence that the Pledge Account and all of the Eligible
Securities are held by it for the account of the Bank as agent for the
Participating Banks and to send notice thereof to the Bank; (iii) on or before
11:00 a.m. (New York City time) on the 15th Business Day of each calendar month
(commencing with January, 1997) or at such other times as the Bank may
reasonably request, the Custodian will provide the Bank and the Pledgor an
account valuation statement, identifying all Eligible Securities and their Value
(as defined in the Pledge Agreement) as of the last Business Day of the
preceding calendar month or as of such other times and the amount of cash held
in the Pledge Account on such last Business Day or as of such other times, and
any other information about the Eligible Securities which the Bank may
reasonably request; (iv) follow the instructions of the Bank, without the
consent of the Pledgor, with respect to the Pledge Account and the Eligible
Securities (including, without limitation, instructions to sell or transfer the
Eligible Securities or instructions to hold dividends, distributions and
interest declared, made or paid upon any of the Eligible Securities as
additional collateral for the Bank, Participating Banks and the Agent or to
deliver Eligible Securities to the Bank); and (v) enter into a Confirmation and
Agreement.

     The Pledgor hereby represents and warrants to, and agrees with, the
Custodian as follows:

          (a) The execution, delivery and performance by the Pledgor of this
     Agreement,  the Pledge Agreement and the Custodian Agreement are (i) within
     its powers, (ii) have been duly authorized by all necessary action and
     (iii) will not (A) contribute to or result in a breach of or default under
     or conflict with any existing law, order, regulation or ruling of any
     governmental or regulatory agency or authority, any order, writ, injunction
     or ruling of any court or other tribunal or any indenture, lease,
     agreement, instrument or other undertaking to which the Pledgor is a party
     or by which it or its property or assets may be bound or affected, or (B)
     result in the imposition of any lien or encumbrance on any property or
     assets of the Pledgor (other than as contemplated by this Agreement) or (C)
     require any approval or consent of, or filing with, any governmental or
     regulatory or any other Person (as defined in the Reimbursement Agreement)
     or (D) violate any provision of the Pledgor's certificate of incorporation,
     memorandum of association or by-laws or any amendment thereof;

          (b) This Agreement is a legally valid and binding obligation of the
     Pledgor, enforceable against the Pledgor in accordance with its terms,
     except as such enforceability may be limited by bankruptcy, insolvency,
     reorganization.


                                      65
<PAGE>
 
     moratorium or other laws or equitable principles relating to or limiting
     the rights of creditors generally;

          (c) It shall forthwith upon the delivery of the Eligible Securities
     register the Pledge Agreement and the Custodian Agreement (as an exhibit to
     the Reimbursement Agreement dated as of November 22, 1996 among the
     Pledgor, the Banks listed therein and the Bank, as Issuing Bank and as
     Agent) in the Register of Charges with the Registrar of Companies in
     Bermuda in accordance with Section 55 of the Companies Act 1981, as
     amended, and pay the registration fee applicable thereon; and

          (d) None of the execution, delivery or performance of this Agreement
     or the Pledge Agreement or the Custodian Agreement, nor the registration
     thereof will be subject to ad valorem stamp duty in Bermuda.

     The Custodian agrees that it shall exercise reasonable care and diligence
in performing all of its obligations hereunder; provided, however, that, as
between the Pledgor and the Custodian:

          (a) The Custodian shall be entitled to rely upon the authenticity of,
     and the truth of the statements in, any certificate, opinion of counsel,
     evidence of indebtedness, notice, consent, instruction or other document
     reasonably believed by the Custodian to be genuine and to be signed by the
     proper party or parties;

          (b) The Custodian shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in reliance upon the advice of
     its legal counsel;

          (c) The Custodian shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith at the instruction of the Bank,
     provided that such action is in accordance with the terms and conditions of
     this Agreement; and

          (d) The Custodian shall be entitled to request the written consent or
     instructions of the Bank for the Custodian prior to taking any action
     hereunder requiring the exercise of its discretion and may refrain from
     taking such action until it shall have received such written consent or
     instructions.

     Subject to the terms of the Pledge Agreement, the Custodian is authorized
to follow and rely upon all instructions given by the Pledgor by tested telex,
or facsimile transmission with receipt confirmed, or written instrument signed
by any officer of the Pledgor or any one of the individuals and officers
identified from time to time in resolutions contained in a certificate signed by
an officer of the Pledgor.


                                      66
<PAGE>
 
     This Agreement may not be amended except by a writing signed by both the
parties hereto and the Bank and no provision of the Pledge Agreement which
affects the obligations or responsibilities of the Custodian may be amended
without the prior, written consent of the Custodian. This Agreement may be
signed in any number of counterparts with the same effect as if the signatures
thereto and hereto were upon the same instrument and shall be binding upon and
inure to the benefit of the parties hereto and the Bank, their successors and
permitted assigns. The parties hereto agree that the Pledgor's agreement with
the Custodian governing custody of the Pledgor's assets shall be deemed to be
modified or superseded in the manner set forth in the Pledge Agreement, this
Agreement and Exhibit B to the Pledge Agreement with respect to the Eligible
Securities and other collateral subject to the Pledge Agreement.

     The Pledgor agrees that it will pay all of the fees and expenses of the
Custodian properly and reasonably incurred in connection with the execution and
performance of the Pledge Agreement and the other agreements attached thereto as
exhibits.

     All obligations performed by the Custodian under this Agreement shall be
performed in the capacity of agent for the Bank.

     This Agreement shall be construed in accordance with and governed by the
laws of Bermuda.

           CONFIRMATION AND AGREEMENT OF THE BANK OF BERMUDA LIMITED

Re:  Pledge and assignment to Morgan Guaranty Trust Company of New York, as
     agent, of Securities Owned by A.C.E. Insurance Company, Ltd. and Held by
     The Bank of Bermuda Limited, as Custodian

Dear Sirs:

     Reference is made to the pledge and assignment to Morgan Guaranty Trust
Company of New York, as agent (the "Bank"), by A.C.E. Insurance Company, Ltd.
(the "Pledgor") of certain securities and the proceeds thereof (including cash)
of the Pledgor (the "Eligible Securities") held by The Bank of Bermuda Limited
(the "Custodian") pursuant to a Pledge Agreement (the "Pledge Agreement") dated
as of November 22, 1996, a list of which is set forth in a written addendum
thereto, which may be amended from time to time by the Pledgor and the Bank. It
is understood that the Eligible Securities are to be held by the Custodian as
the Bank's agent subject to a pledge and assignment and charge in the Bank's
favor as hereinafter set forth, as security for all amounts owed to the Bank and
(as defined in the Pledge Agreement) the Participating Banks and the Agent by
the Pledgor from time to time in connection with letters of credit issued by the
Bank for the Pledgor's Account (as hereinafter defined) pursuant to the
Reimbursement Agreement (as defined therein).

     The Eligible Securities will be held in the Pledge Account (as defined in

     The Custodian hereby confirms that (i) it is holding all of the Eligible
Securities as agent for and subject to the sole written order or instructions of
the Bank; (ii) it will make appropriate entries on its books to evidence that
the Pledge Account and all of the Eligible Securities are being held by it for
the benefit of the Bank and to send notice thereof to the Bank and will
additionally do so with regard to any securities which at any time and for any
reason become Eligible Securities or any funds which become additional
collateral subject to the charge and pledge and assignment in the Bank's favor
pursuant to the Pledge Agreement; (iii) on or before 11:00 a.m. (New York City
time) on the 15th Business Day of each calendar month (commencing with January,
1997) or at such other times as the Bank may reasonably request, it will provide
the Bank and the Pledgor an account valuation statement, identifying all
Eligible Securities and their Value (as defined in the Pledge Agreement) as of
the last Business Day of the preceding calendar month or as of such other times
and the amount of cash held in the Pledge Account on such last Business Day or
as of such such other times, and any other information about the Eligible
Securities which the Bank may reasonably request; and (iv) it will follow the
instructions of the Bank, without the consent of the Pledgor, with respect to
the Pledge Account and the Eligible Securities (including, without limitation,
instructions to sell or transfer the Eligible Securities or instructions to hold
dividends, distributions and interest declared, made or paid upon any of the
Eligible Securities as additional collateral for the Bank, the Participating
Banks and the Agent or to deliver Eligible Securities to the Bank) without any
duty of inquiry to determine whether such instructions are in accordance with
the Pledge Agreement. The Custodian will credit all dividends (other than
liquidating dividends), distributions and interest declared, made or paid upon
any of the Eligible Securities to the account of the Pledgor until the Bank
notifies the Custodian in writing that a Default (as defined in the
Reimbursement Agreement) has occurred and is continuing. The Custodian agrees
that, upon the liquidation or dissolution (in whole or in part) of the issuer of
any of the Eligible Securities, any sum paid as a liquidating dividend or
otherwise upon or with respect to any of the Eligible Securities shall be held
by the Custodian as additional collateral for the benefit of the Bank.

     The Custodian agrees as follows with respect to the Eligible Securities:
(a) it will have no right of compensation from the Bank; (b) it will look solely
to the Pledgor for payment of its expenses and charges, if any, in connection
with the pledge and assignment to the Bank of the Eligible Securities and the
Bank's instructions with regard thereto; (c) the Eligible Securities will be
maintained free and clear of all liens, safekeeping or other charges and demands
and claims of any nature whatsoever, whether now or hereafter existing, on the
part of the Custodian or in favor of the Custodian or of anyone claiming by,
through or under the Custodian; and (d) if certificates shall at any time be
issued with regard to any of the Eligible Securities which were formerly in
uncertificated form, the Custodian shall hold such certificates as the Bank's
agent.

     The Custodian shall have no duty to require any cash or securities be
delivered to it or to determine that the amount and form of assets constituting
Collateral complies with any applicable requirements under the Pledge Agreement,
nor shall the Custodian be responsible for any Collateral not delivered to or
held by it. Subject to the provisions herein, the Custodian may hold the
securities in nominee, book entry or other form and in


                                      70
<PAGE>
 
any depository or clearing corporation established for the purpose of clearing
and settling such securities.

     The Custodian agrees that it shall exercise reasonable care and diligence
in performing all of its obligations hereunder; provided, however, that:

          (a) The Custodian shall be entitled to rely upon the authenticity
     of, and the truth of the statements in, any certificate, opinion of
     counsel, evidence of indebtedness, notice, consent, instruction or other
     document reasonably believed by the Custodian to be genuine and to be
     signed by the proper party or parties;

          (b) The Custodian shall be entitled to rely upon the written
     advice of its legal counsel;

          (c) The Custodian shall not be liable with respect to any action
     taken or omitted to be taken by it in good faith at the instruction of the
     Bank, provided that such action is in accordance with the terms and
     conditions of this Agreement;

          (d) The Custodian shall be entitled to request the written consent or
     instructions of the Bank prior to the Custodian's taking any action
     hereunder requiring the exercise of its discretion and to refrain from
     taking such action until it shall have received such written consent or
     instructions;

          (e) As between the Pledgor and the Custodian, the terms of the
     Custodian Agreement shall apply with respect to any losses or liabilities
     of such parties arising out of matters covered by this Agreement;

          (f) With respect to Eligible Securities held by a central
     depository or clearing corporation, it is understood that the Custodian
     shall have no liability to the Bank in respect of any action or omission of
     the central depository or clearing corporation; and

          (g) To the extent any conflict exists between the obligations of
     the Custodian to perform under the Custodian Agreement and the obligations
     of the Custodian to perform hereunder, the obligations hereunder shall
     supersede any conflicting obligations under the Custodian Agreement.

     All obligations performed by the Custodian under this Agreement shall be
performed in the capacity of agent for the Bank.


                                      71

by written instrument and signed by any officer or designated representative of
the Bank notified to the Custodian in writing. Forthwith after execution of the
Custodian Agreement the Bank will certify to the Custodian the names and
signatures of the persons authorized to sign any proper instructions and

the Custodian appropriate evidence of such authority. The Bank shall promptly
notify the Custodian of any changes that may be made from time to time in the
persons so authorized.

     This Agreement may not be amended except by a writing signed by both of the
parties hereto and no provision of the Pledge Agreement which affects the
obligations or responsibilities of the Custodian may be amended without the
prior, written consent of the Custodian. This Agreement may be signed in any
number of counterparts with the same effect as if the signatures thereto and
hereto were upon the same instrument and shall be binding upon and inure to the
benefit of the parties hereto, their successors and assigns.

     The Custodian hereby represents and warrants to the Bank as follows:

          (a) The execution, delivery and performance by the Custodian of this
     Agreement are (i) within its corporate powers and (ii) have been duly
     authorized by all necessary corporate action;

          (b) This Agreement is a legally valid and binding obligation of the
     Custodian, enforceable against the Custodian in accordance with its terms;
     and

          (c) No authorization, approval or other action by, and no notice to or
     filing with any shareholder of the Pledgor, creditor or governmental or
     regulatory agency or authority is required for the due and valid execution,
     delivery and performance of this Agreement by the Custodian.

     This Agreement shall be construed in accordance with and governed by the
law of Bermuda. The parties hereby consent to the jurisdiction of a state or
federal court situated in New York City, New York in connection with any

                                FIRST AMENDMENT
                                       OF
                   ACE LIMITED 1995 LONG-TERM INCENTIVE PLAN
                   -----------------------------------------



     WHEREAS, ACE Limited ("ACE") maintains the ACE Limited 1995 Long-Term
Incentive Plan (the "Plan"); and

     WHEREAS, amendment of the Plan is now considered desirable;

     NOW, THEREFORE, by virtue and in exercise of the amending power reserved to
ACE under the Plan and pursuant to the authority delegated to the undersigned
officer of ACE by a resolution adopted by its Board of Directors, the Plan be
and is hereby amended in the following particulars, effective as of  November
15, 1996; provided that for purposes of determining a Participant's Years of
Service and Date of Termination, as defined in the Plan, with respect to any
Awards granted under the Plan on or after the Effective Date of the Plan, the
Participant's service as a Director of ACE or as an employee of ACE or a Related
Company prior to November 15, 1996 will be taken into account under the terms of
the Plan:

     1.   By substituting the following for subsection 1.1:

          "1.1  Purpose.  The ACE Limited 1995 Long-Term Incentive Plan (the
     'Plan') has been established by ACE Limited (the 'Company') to:

     (a)  attract and retain Directors of the Company and employees of the
          Company and Related Companies;

     (b)  motivate participating employees and Directors, by means of
          appropriate incentives, to achieve long-range goals;

     (c)  provide incentive compensation opportunities that are competitive with
          those of other major corporations; and

     (d)  further identify Participants' interests with those of the Company's
          other shareholders through compensation that is based on the Company's
          common stock;

     and thereby promote the long-term financial interest of the Company and the
     Related Companies, including the growth in value of the Company's equity
     and enhancement of long-term shareholder return."
<PAGE>
 
     2.   By substituting the following for the first sentence of subsection
          1.2:

          "Subject to the terms and conditions of the Plan, the Committee shall
          determine and designate, from time to time from among the employees of
          the Employers and from among the Directors of the Company those
          persons who will be granted one or more Awards under the Plan, and
          thereby become 'Participants' in the Plan."

     3.  By substituting the following for subsection 2.1:

          "2.1. Definitions. The grant of an Option under this Section 2
     entitles the Participant to purchase shares of Stock at a price fixed at
     the time the Option is granted, or at a price determined under a method
     established at the time the Option is granted, subject to the terms of this
     Section 2.  Options granted under this Section 2 may be either Incentive
     Stock Options or Non-Qualified Stock Options, as determined in the
     discretion of the Committee, except that, to the extent required by the
     Code, a Director who is not an employee of the Company or a Related Company
     may not be granted an Incentive Stock Option.  An 'Incentive Stock Option'
     is an Option that is intended to satisfy the requirement applicable to an
     'incentive stock option' described in section 422(b) of the Code.  A 'Non-
     Qualified Option' is an Option that is not intended to be an 'incentive
     stock option' as that term is described in section 422(b) of the Code.

     4.   By substituting the following for paragraph (b) of subsection 2.4:

     "(b)  No Option may be exercised by a Participant:  (i) prior to the date
           on which the Participant completes one Year of Service with the
           Company or any Related Company after the date as of which the Option
           is granted (provided, however, that the Committee may permit earlier
           exercise following the Participant's Date of Termination by reason of
           death or Disability); or (ii) after the Expiration Date applicable to
           that Option."

     5.    By substituting the following for paragraph (b) of subsection 3.3:

     "(b)  If a Stock Appreciation Right is not in tandem with an Option, then
           the Stock Appreciation Right shall be exercisable in accordance with
           the terms established by the Committee in connection with such
           rights; provided, however, that except as otherwise expressly
           provided in the Plan, no Stock Appreciation Right may

                                      -2-
<PAGE>
 
           be exercised by a Participant (i) prior to the date on which he
           completes one Year of Service with the Company or any Related Company
           after the date as of which the Stock Appreciation Right is granted
           (provided, however, that the Committee may permit earlier exercise
           following the Participant's Date of Termination by reason of death or
           Disability); or (ii) after the Expiration Date applicable to that
           Stock Appreciation Right."

     6.  By substituting the following for subsection 6.5:

     "6.5.  Liability for Cash Payments.  Subject to the provisions of this
     Section 6, an Employer shall be liable for payment of cash due under the
     Plan with respect to any Participant to the extent that such benefits are
     attributable to the services rendered for that Employer by the Participant
     and the Company shall be liable for payment of cash due under the Plan with
     respect to any Participant to the extent that such benefits are
     attributable to the services rendered for the Company as a Director.  Any
     disputes relating to liability of Employers and the Company for cash
     payments shall be resolved by the Committee."

     7.    By substituting the following for paragraph (b) of subsection 6.13:

     "(b)  The Plan does not constitute a contract of employment, and neither
           the Plan nor Awards granted under the Plan, nor selection as a
           Participant, shall confer any right upon a Participant to be retained
           in the employ of an Employer or any Related Company or to be retained
           as a Director of the Company, nor any right or claim to any benefit
           under the Plan, unless such right or claim has specifically accrued
           under the terms of the Plan.  Except as otherwise provided in the
           Plan, no Award under the Plan shall confer upon the holder thereof
           any right as a shareholder of the Company prior to the date on which
           he fulfills all service requirements and other conditions for receipt
           of such rights."

     8.    By substituting the following for paragraph (a) of subsection 8.2:

     "(a)  Subject to the provisions of the Plan, the Committee will have the
           authority and discretion to select employees and Directors to receive
           Awards, to determine the time or times of receipt, to determine the
           types of Awards and the number of shares covered by the Awards, to
           establish the terms, conditions, performance criteria, restrictions,
           and other

                                      -3-
<PAGE>
 
           provisions of such Awards, and to cancel or suspend Awards.  In
           making such Award determinations, the Committee may take into account
           the nature of services rendered by the respective employee or
           Director, his present and potential contribution to the Company's
           success and such other factors as the Committee deems relevant."

     9.    By substituting the following for subsection 8.4:

     "8.4  Information to be Furnished to Committee.  The Employers and Related
     Companies shall furnish the Committee with such data and information as may
     be required for it to discharge its duties.  The records of the Employers
     and Related Companies as to an employee's or Participant's employment, a
     Director's term of service, termination of employment, termination as a
     Director, leave of absence, reemployment and compensation shall be
     conclusive on all persons unless determined to be incorrect.  Participants
     and other persons entitled to benefits under the Plan must furnish the
     Committee such evidence, data or information as the Committee considers
     desirable to carry out the terms of the Plan.

     10.   By substituting the following for paragraph (e) of Section 10:

     "(e)  Date of Termination.  A Participant's 'Date of Termination' shall be,
           with respect to an employee, the date on which his employment with
           all Employers and Related Companies terminates for any reason, and
           with respect to a Director, the date immediately following the last
           day on which he serves as a Director; provided that a Date of
           Termination shall not be deemed to occur by reason of a Participant's
           transfer of employment between the Company and a Related Company
           (including an Employer) or between two Related Companies (including
           Employers); further provided that a Date of Termination shall not be
           deemed to occur by reason of a Participant's cessation of service as
           a Director if immediately following such cessation of service he
           becomes or continues to be employed by the Company or a Related
           Company, nor by reason of a Participant's termination of employment
           with the Company or a Related Company if immediately following such
           termination of employment he becomes or continues to be a Director;
           and further provided that a Participant's employment shall not be
           considered terminated while the Participant is on a leave of absence
           from an Employer or a Related Company approved by the Participant's
           employer."

                                      -4-
<PAGE>
 
     11.   By redesignating paragraphs (f) through (p) of Section 10 as
           paragraphs (g) through (q) and adding the following new paragraph
           (f):

     "(f)  Director.  The term 'Director' means a member of the Board, who may
     or may not be an employee of the Company or a Related Company."

     12.   By substituting the following for subparagraph (n), redesignated as
           subparagraph (o), of Section 10,:

     "(o)  Retirement.  'Retirement' of a Participant shall mean with respect to
           an employee of the Company or a Related Company, the occurrence of a
           Participant's Date of Termination with the consent of the
           Participant's employer after the Participant is eligible for early
           retirement or normal retirement under the ACE Limited Employee
           Retirement Plan (or any other retirement plan maintained by the
           Company or the Related Companies) and with respect to a Director, the
           Participant's Date of Termination with the consent of the Company
           after the Participant would be eligible for retirement under any
           retirement plan maintained by the Company or a Related Company if the
           Director were an employee of the Company or a Related Company;
           provided, however, that the Committee may impose such additional or
           alternative conditions or restrictions on Retirement as it determines
           to be appropriate."

     13.   By adding the following new paragraph (r) to the end of Section 10:

     "(r)  Year of Service.  The term 'Year of Service' means one continuous
     year of employment with the Company or a Related Company, one continuous
     year of service as a Director of the Company, or one continuous year of any
     combination of employment with the Company or a Related Company and service
     as a Director."

1.  At June 30, 1994, the Company increased its then existing reserves relating
to breast implant claims. Although the reserve increase was partially satisfied
by an allocation from existing IBNR, it also required an increase in the
Company's total reserve for unpaid losses and loss expenses at June 30, 1994 of
$200 million (see "Management's Discussion and Analysis - Breast Implant
Litigation"). In 1992, the Company began applying actuarial and statistical
methods to estimate ultimate expected losses and loss expenses. The recording of
$463 million of losses and loss expenses in 1992 resulted from the application
of these methods to all of the Company's business since inception. Of such
amount, $236 million related to premiums earned in years prior to 1992 and $227
million related to premiums earned in 1992.

2.  Earnings (loss) per share are computed using net income (loss) divided by
the weighted average number of Ordinary Shares outstanding and, if dilutive,
shares issuable under outstanding options. There is no material difference
between primary and fully diluted earnings (loss) per share.

3.  Pro forma earnings per share have been calculated by dividing net income by
the weighted average number of Ordinary Shares and Ordinary Share equivalents
outstanding as adjusted

The following is a discussion of the Company's financial condition, results of
operations, liquidity and capital resources. This discussion should be read in
conjunction with the consolidated financial statements, and related notes
thereto, presented on pages 28 to 45 of this annual report.

  md&a

  Management's discussion and analysis of results of operations and financial
condition

  General

  ACE Limited ("ACE") is a holding company which, through its Bermuda-based
operating subsidiaries, A.C.E. Insurance Company, Ltd. ("ACE Insurance"),
Corporate Officers & Directors Assurance Ltd. ("CODA") and Tempest Reinsurance
Company Limited ("Tempest") provides insurance and reinsurance for a diverse
group of international clients.  In addition, the Company provides funds at
Lloyd's of London ("Lloyd's") to support underwriting by syndicates managed by
Methuen Underwriting Limited ("MUL"). The term "the Company" refers to ACE and
its subsidiaries, excluding Methuen.

  On July 1, 1996, the Company completed the acquisition of Tempest, a leading
Bermuda-based property catastrophe reinsurer.  Tempest underwrites property
catastrophe reinsurance on a worldwide basis, emphasizing excess layer
coverages, and has large aggregate exposures to man-made and natural disasters.
Property catastrophe loss experience is generally characterized as low frequency
but high severity short-tail claims which may result in significant volatility
in financial results. (For further discussion, see "Liquidity and Capital
Resources").

  On March 27, 1996, the Company acquired a controlling interest in Methuen
Group Limited ("Methuen"), the holding company for MUL, a leading Lloyd's
managing agency.  On November 26, 1996 the Company acquired the remaining 49
percent interest in Methuen. MUL manages six syndicates with a total
underwriting capacity of (Pounds)366 million (approximately $555 million) in
1996.  For the 1996 year of account, the Company, through a corporate
subsidiary, has participated in the underwriting of these syndicates by
providing funds at Lloyd's of (Pounds)12.25 million (approximately $18 million),
which was primarily in the form of a letter of credit, supporting (Pounds) 24.5
million (approximately $37 million) of underwriting capacity.  For the 1997 year
of account, the Company has agreed to provide funds at Lloyd's of approximately
(Pounds)62 million (approximately $93 million) to support up to approximately
(Pounds)124 million (approximately $186 million) of premium writing capacity by
Methuen syndicates. The Methuen syndicates in which the Company participates
underwrite aviation, marine and non-marine risks.

  On November 26, 1996 the Company acquired Ockham Worldwide Holdings PLC
("Ockham Worldwide"), a wholly-owned subsidiary of Ockham Holdings PLC. Ockham
Worldwide owns two Lloyd's managing agencies, Ockham Sturge Aviation Agency Ltd.
and Ockham Worldwide Agency Ltd.  Upon completion of the acquisition, the two
managing agencies changed their names to ACE London Aviation Limited and ACE
London Underwriting Limited. Together these two agencies manage seven syndicates
with total underwriting capacity of (Pounds) 349 million (approximately $524
million) in 1996.  Ockham Worldwide also owns a Lloyd's corporate member which
provides funds at Lloyd's to support underwriting on these syndicates.  The
Company expects to provide approximately (Pounds)15 million (approximately $23
million) of capacity to the syndicates managed by Ockham Worldwide for the 1997
year of account.

  The Company's excess liability insurance policy generally provides limits of
up to a maximum of $200 million per occurrence and annual aggregate, with a
minimum attachment point generally of $100 million. For all new and renewal
business, effective December 15, 1994, the Company reduced the maximum limits
offered for integrated occurrences from $200 million to $100 million.  The
Company maintains excess of loss clash reinsurance to protect it from losses
arising from a single set of circumstances (occurrence) covered by more than one
excess liability insurance policy.  The reinsurance provides protection to a
maximum of $150 million, and in the aggregate excess of $225 million, for each
and every loss occurrence involving three or more insureds. Integrated
occurrences are specifically excluded.

  The Company offers up to $75 million of limits in directors and officers
liability coverage.  The Company does not purchase reinsurance for its directors
and officers liability risks.

  The Company began satellite insurance operations in February 1994.  Until
February 15, 1996, the Company offered separate limits of up to $25 million per
risk for launch insurance, including ascent to orbit and/or initial testing, and
up to $25 million per risk for in-orbit insurance.  This risk was fully retained
by the Company.  Effective for all business written on or after

February 15, 1996, the Company has entered into a surplus treaty arrangement
which provides for up to $25 million of reinsurance for each risk. This
reinsurance arrangement has enabled the Company to raise the gross limits
offered for satellite insurance to $50 million per risk.

  During fiscal 1995, the Company entered the following new lines of business:
aviation insurance, excess property insurance, and financial lines. Also during
1995, the Company commenced its participation in the reinsurance of "First
Line".

  Aviation insurance provides coverage for various aviation products, including
aircraft manufacturer's hull and liability, as well as airport liability,
aircraft refueling operations and associated aircraft liability risks. The
Company offers limits of up to $100 million per insured, with no minimum
attachment point. The Company reduces its net exposure to approximately $50
million per insured, with a dedicated reinsurance program.

  The Company offers global excess property "all risk" insurance, providing
limits of up to a maximum of $50 million per occurrence with a minimum
attachment point of $25 million. Coverage includes such perils as windstorm,
earthquake and fire, as well as explosion. Consequential business interruption
coverage is also offered. In certain circumstances, the Company uses reinsurance
to establish the retained net limit per risk. In addition, the Company has
purchased catastrophe reinsurance to control the possible effects of cumulative
natural peril exposure.

  The Company's financial lines product group offers specifically designed
financial, insurance and reinsurance solutions to address complex risk
management problems. The programs offered typically have the following common
characteristics: multi-year contract terms, broad coverage that includes stable
capacity and pricing for the insured, aggregate policy limits and insured
participation in the results of their own loss experience. Each contract is
unique because it is tailored to the insurance or reinsurance needs, specific
loss history and financial strength of the insured. Premium volume, as well as
the number of contracts written, can vary significantly from period to period
due to the nature of the contracts being written. Profit margins may vary from
contract to contract depending on the amount of underwriting risk and investment
risk assumed on each contract.

  The Company participates in the reinsurance of a program referred to as "First
Line" which provides financial guarantees required by the U.S. Coast Guard to
issue Certificates of Financial Responsibility, under the Oil Pollution Act of
1990, to owners of vessels operating in U.S. waters. The Company has purchased
excess of loss reinsurance to limit its exposure in this line.

  The Company will continue to evaluate potential new product lines and other
opportunities in the insurance and reinsurance markets.

  During the years ended September 30, 1996 and 1995, the Company has
experienced strong growth in net premiums earned and net investment income,
offset partially by an increase in general and administrative expenses. These
factors, together with the inclusion of income excluding net realized gains on
investments of $23.8 million from Tempest for the three month period from July
1, 1996, the date of acquisition, resulted in income excluding net realized
gains on investments of $234.5 million in 1996.

  For 1995, these same factors, excluding Tempest, resulted in income excluding
net realized gains on investments of $186.8 million. Fiscal 1994 income
excluding net realized gains on investments was adversely affected by an
additional charge of $200 million in the Company's reserve for unpaid losses and
loss expenses which was primarily related to breast implant litigation resulting
in a net loss excluding net realized gains on investments of $49.4 million (see
"Losses and Loss Expenses" and "Breast Implant Litigation").

</TABLE>

  The Company's ability to make strategic acquisitions, develop new product
lines and maintain high renewal rates on existing business despite continuing
competitive pressure in certain markets, particularly the excess liability and
directors and officers liability markets, has resulted in increases in net
premiums written and net premiums earned for the years ended September 30, 1996
and 1995.

  Net premiums written increased by $177.9 million or 41.9 percent in 1996
compared to 1995. This growth is a result of a very strong year for the
Company's financial lines and satellite product lines together with the
increased contributions from aviation and excess property insurance which both
include a full year of underwriting in 1996. Net premiums written also include
property catastrophe premiums written by Tempest from July 1, 1996, as well as
premiums from the Company's participation in the Lloyd's syndicates managed by
MUL. These increases were offset by decreases in excess liability and directors
and officers liability premiums written in 1996. Limit reductions, some of which
resulted from reduced integrated occurrence coverages and increases to higher
attachment points on some business written, contributed to the decrease in
excess liability premiums. Continuing competitive pressures in the excess
liability market also contributed to the decline in this line of business. The
decline in directors and officers premiums is primarily due to a lower level of
premiums generated from multi-year policies and premium decreases due to the
continuing competitive pressure in the directors and liability market, offset
somewhat by a net increase in new business.

  The increase in net premiums written of $38.9 million or 10.1 percent in 1995
as compared to 1994 was mainly the result of strong growth in the Company's
satellite insurance business and the contributions of the Company's new product
lines. The Company continued its program of selective premium rate increases for
excess liability accounts in the chemical, energy, petrochemical and
medical/pharmaceutical industries. However, a combination of the Company's
decision to impose an annual aggregate sublimit of $100 million for excess
liability integrated occurrences and an increase in competition in the
marketplace was primarily responsible for the net decrease in excess liability
net premiums written of $27.9 million. The slight decrease of $2.5 million in
directors and officers liability net premiums written during 1995 was primarily
the result of reduced premiums from multi-year policies and continuing
competitive pressures in that marketplace. These factors were partially offset
by an additional month of CODA net premiums written in 1995 as compared with
1994. CODA was acquired by the Company on November 1, 1993

                                      20

and accordingly, eleven months of CODA net premiums written were recognized
during fiscal 1994 as compared with twelve months in 1995.

  For fiscal 1996, net premiums earned increased by $158.5 million to $587.2
million compared with $428.7 million in 1995.  The increase was the result of
contributions from the new lines of business, particularly financial lines,
together with the increase in satellite premiums earned, primarily from launch
insurance, and the inclusion of Tempest earned premiums since July 1, 1996, the
date of acquisition, which amounted to $35.7 million.  These increases were
offset by a decline in excess liability and directors and officers liability
premiums earned in the year.

  Net premiums earned increased by $37.6 million for 1995 as compared with 1994
due mainly to satellite insurance business which added $35.2 million and new
product lines which together contributed $12.5 million offsetting declines
primarily in excess liability and directors and officers liability in the
aggregate of $10.4 million. Net premiums earned from excess liability and
directors and officers liability declined primarily as a result of the
imposition of the annual aggregate sublimit for excess liability integrated
occurrences and an increase in competition in the marketplace.

  The increases in net investment income in 1996 and 1995 were primarily
attributable to a larger investable asset base.  On average, the portfolio
generated a lower yield in 1996 compared to 1995 as a result of general market
conditions while higher average yields were generated in 1995 as compared to
1994.  The increases in the investable asset base in both 1996 and 1995 were due
to positive cash flows from insurance operations and the reinvestment of funds
generated by the portfolio.  The increase in 1996 was also the result of the
consolidation of the Tempest portfolio on July 1, 1996.

</TABLE>

  The Company's investment strategy takes a long-term view and the portfolio is
actively managed to maximize total return within certain specific guidelines
which minimize risk.  The portfolio is reported at fair value. The effect of
market movements on the investment portfolio will directly impact net realized
gains (losses) on investments when securities are sold. Changes in unrealized
gains and losses, which result from the revaluation of securities held, are
reported as a separate component of shareholders' equity.

  In May 1996, the Company decided to increase the equity exposure of the
portfolio from 15 percent to 20 percent.  It is expected that this change to the
equity exposure will be fully implemented by the end of the first quarter of
fiscal 1997.  The remainder of the portfolio is comprised of fixed maturity
securities.

  Non-U.S. dollar fixed maturity and equity securities are held in the
portfolio.  The Company's investment guidelines permit the use of foreign
currency forward and option contracts to minimize the effect of fluctuating
foreign currencies on the value of non-U.S. dollar holdings.  The contracts used
are not designated as specific hedges and therefore, realized and unrealized
gains and losses recognized on these contracts are recorded as a component of
net realized gains (losses) on investments in the period in which the
fluctuations occur, together with net foreign currency gains and losses
recognized when non-U.S. dollar securities are sold.

  Sales proceeds for fixed maturity securities were generally higher than their
amortized costs during fiscal 1996 which resulted in net realized gains on
investments of $14.4 million compared to gains of $8.4 million during 1995. In
fiscal 1994, decreasing market values created by rising interest rates resulted
in sales proceeds for securities which were generally less than their amortized
cost, with net realized losses of $43.3 million being recognized on fixed
maturities and short-term investments.

  With strong equity markets, net realized gains on sales of equity securities
were $15.8 million in fiscal 1996 compared with gains of $3.6 million in 1995.
In fiscal 1994, the Company's equity exposure was obtained solely through the
use of a synthetic equity fund. In addition to the synthetic equity fund, during
fiscal 1995, common stocks were introduced into the portfolio as part of the
implementation of changes to the strategic asset allocation.

  The realized gains on financial futures contracts were generated from U.S.
Treasury futures contracts and from the equity index futures contracts held in
the synthetic equity fund. Gains and losses on these instruments are closely
linked to fluctuations in the U.S. Treasury and equity markets and therefore,
realized gains would be expected during periods of broad market improvements
while losses are realized during periods of market declines.

  The majority of the $26.7 million of net realized gains on financial futures
contracts recorded in 1996 were generated by the equity index futures contracts
held, as a result of the 20 percent rise in the S&P 500 Stock Index during the
fiscal year. This compares with $39.8 million generated in 1995 as a result of
the nearly 30 percent rise in the S&P 500 Stock Index during the period. The
remainder arose from gains recognized on futures contracts used by certain of
the Company's external managers of fixed income securities (see note 7(a) of the
Notes to Consolidated Financial Statements for a discussion of the Company's use
of financial futures contracts). In comparison, net realized losses on financial
futures contracts of $11.1 million were generated during 1994 by the equity
index futures contracts and future contracts on fixed income securities. Most of
the losses were derived from the U.S. Treasury futures contracts and were a
direct result of the increase in intermediate and long-term interest rates
during the twelve month period which resulted in market depreciation for fixed
income securities.

  Currency losses for the year were $1.7 million compared to a loss of $1.0
million for 1995. Unrealized currency losses of $7.2 million on securities held
in the portfolio as at September 30, 1996 are reflected in net unrealized
appreciation on investments in shareholders' equity. At September 30, 1995 there
was an unrealized currency gain of $1.7 million in net unrealized appreciation
on investments in shareholders' equity.

  In fiscal 1994, the Company sold its voting common shares of Centre Re, a
privately held Bermuda-domiciled reinsurer specializing in finite risk
reinsurance, to Zurich Insurance Company, the controlling shareholder of Centre
Re, for $128.4 million and recognized a gain of $58.1 million. The proceeds from
the sale, and interest thereon, were received by the Company in February 1994,
and integrated into the Company's investment portfolio.

  The underwriting results of a property and casualty insurer are discussed
frequently by reference to its loss and loss expense ratio, acquisition cost
ratio, administrative expense ratio and combined ratio. Each ratio is derived by
dividing the relevant expense amounts by net premiums earned. The combined ratio
is the sum of the loss and loss expense ratio, acquisition cost ratio and the
administrative expense ratio. A combined ratio under 100 percent indicates
underwriting profits and a combined ratio exceeding 100 percent indicates
underwriting losses.

  For the year ended September 30, 1996, the loss and loss expense ratio was
79.1 percent. This ratio has been impacted by the inclusion of Tempest since
July 1, 1996, the date of acquisition. Property catastrophe loss experience is
generally characterized as low frequency but high severity short-tail claims
which may result in significant volatility in results. For the period from the
date of acquisition of Tempest to September 30, 1996, Tempest's loss and loss
expense ratio was 36.4 percent. Excluding the impact of Tempest, the loss and
loss expense ratio for fiscal 1996 would have been 81.8 percent. For the year
ended September 30, 1995 the loss and loss expense ratio was also 81.8 percent.
The loss and loss expense ratio for 1994 was significantly impacted by an
additional $200 million charge to earnings which related to increases in the
reserve for unpaid losses and loss expenses primarily related to breast implant
litigation. Excluding the additional charge, the loss and loss expense ratio for
1994 would have been 82.0 percent and the combined ratio would have been 98.0
percent.

  Several aspects of the Company's operations, including the low frequency and
high severity of losses in the high excess layers in certain lines of business
in which the Company provides insurance and reinsurance, complicate the
actuarial reserving techniques utilized by the Company. Management believes,
however, that the Company's reserve for unpaid losses and loss expenses,
including those arising from breast implant litigation, are adequate to cover
the ultimate cost of losses and loss expenses incurred through September 30,
1996. Since such provisions are necessarily based on estimates, future
developments may result in ultimate losses and loss expenses significantly
greater or less than such amounts (see "Breast Implant Litigation").

  Acquisition costs have increased by $6.4 million in 1996 compared with 1995 as
a result of the significant increase in net premiums earned. However, the
acquisition cost ratio decreased to 9.0 percent in 1996 from 10.9 percent in
1995 primarily due to the change in the mix of premiums earned in the year. The
acquisition cost ratio decreased in 1995 compared with 1994 primarily as a
result of generally lower commission rates on satellite insurance.

  Administrative expenses increased by $15.6 million in 1996 compared with 1995
and $9.1 million in 1995 compared with 1994. These additional expenses are
primarily due to the increased cost base resulting from the strategic
diversification by the Company over the past two years, including the
introduction of the new insurance products during 1994 and 1995 and the
acquisition of Tempest and Methuen during 1996. Administrative expenses for 1996
include $1.3 million related to the amortization of goodwill resulting from the
acquisition of Tempest. In addition, the increase in the market value of the
Company's shares during 1996 and 1995 resulted in total expenses related to
employee stock appreciation rights of $6.0 million and $2.5 million
respectively, compared with a credit of $1.4 million in 1994.

  Liquidity and Capital Resources

  As a holding company, ACE's assets consist primarily of the stock of its
subsidiaries as well as other investments. In addition to investment income, its
cash flows depend primarily on dividends or other statutorily permissible
payments from its Bermuda-based insurance and reinsurance subsidiaries (the
"Bermuda subsidiaries"). There are currently no legal restrictions on the
payment of dividends from retained earnings by the Bermuda subsidiaries as the
minimum statutory capital and surplus requirements are satisfied by share
capital and additional paid-in capital of each of the Bermuda subsidiaries.
However, the payment of dividends or other statutorily permissible distributions
by the Bermuda subsidiaries is subject to the need

                                      23

to maintain shareholder's equity at a level adequate to support the level of
insurance and reinsurance operations. On January 4, 1996 the Company received a
dividend of $10 million from ACE Insurance Management Limited and on September
24, 1996 the Company received a dividend of $125 million from ACE Insurance.

  The Company's consolidated sources of funds consist primarily of net premiums
written, investment income, and the proceeds from sales and maturities of
investments. Funds are used primarily to pay claims, operating expenses and 
621.40 dividends and for the purchase of investments.

  For the years ended September 30, 1996, 1995 and 1994, the Company's
consolidated net cash flows from operating activities were $621.40 million,
$437.0 million and $336.8 million respectively. Cash flows are affected by claim
payments, which due to the nature of the Company's operations, may comprise
large loss payments on a limited number of claims and therefore can fluctuate
significantly from year to year. The irregular timing of these loss payments,
for which the source of cash can be from operations, available net credit
facilities or routine sales of investments, can create significant variations in
cash flows from operations between periods. Total loss and loss expense payments
amounted to $101.4 million, $73.1 million and $126.6 million in fiscal 1996,
1995 and 1994, respectively.

  At September 30, 1996, total investments and cash amounted to $4.2 billion
compared with $3.1 billion at September 30, 1995. The significant increase in
investable assets can be attributed in part to the acquisition of Tempest, whose
investable assets have been consolidated with the Company's. Tempest's
investments and cash at September 30, 1996 were approximately $523 million and
are included in total investments and cash. The remainder of the increase is
attributable to strong cash flows from operating activities during the year as
well as the reinvestment of funds generated by the portfolio.

  The Company's consolidated investment portfolio is structured to provide a
high level of liquidity to meet insurance related or other obligations. During
1996, an average of 11.5 percent of the externally managed investment portfolio
was held in short-term investments which mature in one year or less from date of
issue. Additionally, at September 30, 1996, 4.2 percent of the fixed maturity
portfolio had a maturity date within the succeeding twelve month period,
providing a further source of liquid funds. The consolidated investment
portfolio is externally managed by independent professional investment managers
and is invested in high quality investment grade marketable fixed income and
equity securities, the majority of which trade in active, liquid markets (see
note 4 of the Notes to Consolidated Financial Statements for a detailed analysis
of the portfolio). At September 30, 1996, 95 percent of the fixed maturity
portion of the portfolio was rated "A" or better by one or more nationally
recognized U.S. rating agencies. The Company believes that its cash balances,
cash flow from operations, routine sales of investments and the liquidity
provided under its committed line of credit (discussed below) are adequate to
allow the Company to pay claims within the time periods required under its
policies.

  The Company has a $150 million committed unsecured line of credit provided by
a syndicate of five major international banks, led by Morgan Guaranty Trust
Company of New York ("Morgan"). In accordance with the Company's cash management
strategy, this facility is utilized when it is determined that borrowing on a
short-term basis is advantageous to the Company. Borrowings from this facility
are generally repaid from operating cash flows, primarily premium receipts.
There were no drawdowns on the facility during 1996 or 1995. The line of credit
agreement requires the Company to maintain consolidated tangible net worth of
not less than $950 million.

  Upon renewal on November 15, 1996, an additional bank will participate in the
facility, increasing to six the number of banks involved in the syndicate. The
committed unsecured line of credit was renewed in the amount of $50 million for
an additional 364 day period under essentially the same terms and conditions as
expiring. The minimum consolidated tangible net worth covenant was increased to
$1.25 billion, reflecting the growth in the Company's consolidated tangible net
worth to approximately $2 billion at September 30, 1996. The syndicate of banks
have also committed to provide up to (Pounds) 75 million (approximately $112
million) for a five year, secured letter of credit, which will primarily be used
to provide funds at Lloyd's to support underwriting capacity on Lloyd's
syndicates in which the Company participates. Morgan will remain as agent on the
line of credit and will serve as the issuing bank for the letter of credit.

  On July 1, 1996, the Company completed the acquisition of Tempest. Under the
terms of the Agreement and Plan of Amalgamation, Tempest shares outstanding at
the time of the acquisition were cancelled and converted into the right to
receive 13,333,247 Ordinary Shares of the Company. These shares were capitalized
at a value of $46 2/3 per share, which was determined in accordance with the
EITF 95-19 consensus that deals with the value of equity securities issued to
effect a purchase combination. In addition, options to acquire Tempest shares
were converted into 446,089 Company options at a total cost of $12.1 million.
The total value of the acquisition amounted to $638.7 million, which includes
the value of the shares and options issued as well as other transaction expenses
which amounted to $4.4 million.

  Tempest is not an admitted reinsurer in the United States. Accordingly, the
terms of certain reinsurance contracts require Tempest to provide letters of
credit ("LOCs") to Tempest's clients in respect of reported claims. Tempest has
a facility for the issuance of LOCs of up to $20 million. At September 30, 1996,
LOCs outstanding amounted to $8.4 million. Investments with a fair value of
$15.4 million were pledged as collateral for these LOCs.

  During 1995 the Company repurchased 1,332,300 Ordinary Shares under share
repurchase programs for an aggregate cost of $33.5 million. During 1996, the
Company repurchased 1,268,600 Ordinary Shares under share repurchase programs
for an aggregate cost of $57.8 million. On August 9, 1996, the Board of
Directors authorized a new repurchase program for up to $100 million of the
Company's Ordinary Shares. This program superseded and replaced the balance of
the previous authorization. At September 30, 1996, $65.8 million of the current
Board authorization had not been utilized.

  On October 19, 1995, January 18, 1996 and April 19, 1996,

the Company paid quarterly dividends of 14 cents per share to shareholders of
record on September 29, 1995, December 29, 1995, and March 29, 1996
respectively. On July 19, 1996 the Company paid a quarterly dividend of 18 cents
per share to shareholders of record on June 14, 1996. On August 9, 1996, the
Board of Directors declared a quarterly dividend of 18 cents per share paid on
October 18, 1996 to shareholders of record on September 30, 1996. The
declaration and payment of future dividends is at the discretion of the Board of
Directors and will be dependent upon the profits and financial requirements of
the Company and other factors, including legal restrictions on the payment of
dividends and such other factors as the Board of Directors deems relevant.

  Fully diluted net asset value per share was $38.31 at September 30, 1996,
compared with $31.19 at September 30, 1995.

</TABLE>

  The Company maintains loss reserves for the estimated unpaid ultimate
liability for losses and loss expenses under the terms of its policies and
agreements.  The ultimate liability is estimated using actuarial and statistical
projections. The reserve for unpaid losses and loss expenses of $1.8 billion at
September 30, 1996, includes $1.0 billion of case and loss expense reserves.
While the Company believes that its reserve for unpaid losses and loss expenses
at September 30, 1996 is adequate, future developments may result in ultimate
losses and loss expenses significantly greater or less than the reserve
provided.  A number of the Company's insureds have given notice of claims
relating to breast implants or components or raw material thereof that had been
produced and/or sold by such insureds. The Company does not have adequate data
upon which to anticipate any funding schedule for the payment of these
liabilities, and it expects that the amount of time required to determine the
financial impact of the options selected by claimants may extend well into 1997
and beyond.  Payments may be accelerated for some policyholders in 1997 as a
result of settlement of opt-out cases and as additional payments are required to
fund Settlement II (see "Breast Implant Litigation").

  The Company's financial condition, results of operations and cash flow are
influenced by both internal and external forces. Claims settlements, premium
levels and investment returns may be impacted by changing rates of inflation and
other economic conditions.  In many cases, significant periods of time, ranging
up to several years or more, may elapse between the occurrence of an insured
loss, the reporting of the loss to the Company and the settlement of the
Company's liability for that loss.  The liquidity of its investment portfolio,
cash flows and the line of credit are, in management's opinion, adequate to meet
the Company's expected cash requirements.

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

  Breast Implant Litigation

  A number of the Company's insureds have given notice of claims relating to
breast implants or components or raw material thereof that had been produced
and/or sold by such insureds.  Lawsuits, including class actions, involving
thousands of implant recipients have been filed in both state and federal courts
throughout the United States.  Most of the federal cases have been consolidated
pursuant to the rules for Multidistrict Litigation ("MDL") to a Federal District
Court in Alabama.

  On April 1, 1994 the judge presiding over the MDL proceeding gave preliminary
approval to a global settlement agreement in the approximate amount of $4.2
billion and conditional certification to a settlement class ("Global I").

  On May 15, 1995, the Dow Corning Corporation, a significant participant in the
Global I settlement, filed for protection under Chapter 11 of the U.S.
Bankruptcy Code.

  As of June 1, 1995, over 440,000 registrations were received by the Global I
Claims Administrator.  Approximately 248,500 of these were filed by domestic
class members by the September 16, 1994 deadline for making claims under the
Current Disease Compensation Program.  Based on an analysis of about 3,000 of
these registrations, the judge concluded that a severe racheting (or reduction)
of the settlement amounts shown in the notice of settlement would occur if
current claims were evaluated under the existing criteria and if funding of the
Current Disease 

                                       25

[md&a LOGO]                       [ACE LOGO] 

Compensation Program remained at the $1.2 billion level.

  Because of the anticipated racheting of benefit amounts and the defendants'
right to withdraw under the Global I settlement, the judge entered an order on
October 9, 1995 declaring that class members had new opt-out rights and that in
general class members and their attorneys should not expect to receive any
benefits under Global I.

  On October 1, 1995, negotiators for three of the major defendants agreed on
the essential elements of a revised individual settlement plan for domestic
class members with at least one implant from any of those manufacturers
("Settlement II"). In general, under Settlement II, the amounts payable to
individual participants, and the manufacturers' obligations to make those
payments, would not be affected by the number of class members electing to opt
out from the new plan. Also, in general, the compensation would be fixed rather
than subject to potential further racheting, and the manufacturers would not
have a right to walk away because of the amount of claims payable. Finally, each
settling defendant agreed to be responsible only for cases in which its implant
was identified, and not for a percentage of all cases.

  Participants with implants from one or more of those three defendants who had
submitted timely claims under Global I would have two options.

  Option One: An amount based on disease criteria and severity levels in the
Global I settlement ranging from $10,000 to $100,000. Although substantially
less than the amounts shown in the initial notices for Global I settlement, they
are greater for many claimants than the amounts that, after racheting, would
have been offered under Global I and are not subject to a "walkaway" by
defendants because of such opt-outs.

  Option Two: A potentially higher benefit based on having or developing during
a 15-year period certain diseases that meet more restrictive criteria. The
compensation range for persons qualifying under this option is from $75,000 to
$250,000. Qualifying claimants would also be eligible for an advance payment of
$1,000 under certain circumstances. In general, the maximum total obligation
under this 15-year program allocated among the three defendants plus the
additional defendants referred to below is $755 million.

  Each Current Claimant, regardless of the option selected, would be paid an
advance payment of $5,000 and would also be eligible for an additional payment
of $3,000 to defray the costs of explantation during that 15-year period should
the person choose to do so without regard to the status of any appeals. Current
Claimants would be given an extended period of time to identify manufacturers of
their implants, to correct any deficiencies in the documentation supporting
their prior claims or to provide additional support for claims under the more
restrictive criteria.

  By November 13, 1995, Settlement II was approved by the three major
defendants. In addition, two other defendants became part of Settlement II,
although certain of their settlement terms are different and more restricted
than the plan offered by the original three defendants.

  On December 22, 1995, the judge approved Settlement II and the materials for
giving notice to claimants although several appeals concerning Settlement II
have been lodged with the Eleventh Circuit Court of Appeals. In mid-January 1996
the three major defendants each made a payment of $125 million to a court-
established fund as an initial reserve for payments to be made under Settlement
II. The judge in the MDL proceeding has started to remand or transfer opt-out
cases to the originating or other courts for further pre-trial proceedings and
trial. The Claims Administrator has begun sending out notifications of status
and advance payments to claimants who submitted implant manufacturer proof. At
the present time, it cannot be determined how many claimants will accept and
qualify under the terms of Settlement II; similarly, the number of opt-outs
cannot be estimated.

  Although the Company has underwritten the coverage for a number of the
defendant companies including four of the companies involved in the revised
Settlement II described above, the Company anticipates that insurance coverage
issued prior to the time the Company issued policies will be available for a
portion of the defendants' liability. In addition, the Company's policies only
apply when the underlying liability insurance policies or per occurrence
retentions are exhausted.

  Declaratory judgment lawsuits, involving four of the Company's insureds, have
been filed seeking guidance on the appropriate trigger for their insurance
coverage. None of the insureds have named the Company in such lawsuits, although
other insurers and third parties have sought to involve the Company in those
lawsuits. To date, one court has stayed a lawsuit against the Company by other
insurers, a second court has dismissed the claims by other insurers against the
Company. Another court in Texas has ruled against the Company's arguments that
the court should dismiss the claims by other insurers and certain doctors
attempting to bring the Company into coverage litigation there. On appeal in the
Texas lawsuit, the appellate court affirmed the lower court's order refusing to
dismiss the claims against the Company, further appellate review in the Texas
Supreme Court has been sought. In addition, further efforts are contemplated to
stay or dismiss the doctor's claims against the Company in the Texas lawsuit.
The remaining case is presently stayed; if it is activated, the Company will
resist involvement on jurisdictional and other grounds.

  At June 30, 1994, the Company increased its then existing reserves relating to
breast implant claims. Although the reserve increase was partially satisfied by
an allocation from existing IBNR, it also required an increase in the Company's
total reserve for unpaid losses and loss expenses at June 30, 1994 of $200
million. The increase in reserves was based on information made available in
conjunction with Global I (including information relating to opt-outs) and
information made available from the Company's insureds and was predicated upon
an allocation between coverage provided before and after the end of 1985 (when
the Company commenced underwriting operations). No additional reserves relating
to breast implant claims have been added since June 30, 1994.

  The Company believes that its reserves for unpaid losses and loss expenses
including those arising from breast implant claims are adequate as of September
30, 1996. The Company

                                      26
<PAGE>

                                  [ACE LOGO]
 
continually evaluates its reserves in light of developing information and in
light of discussions and negotiations with its insureds. In August 1996, the
Company settled with one of its insureds, a breast implant manufacturer, for a
sum of money to be paid out over a number of years in the future. The settlement
is consistent with the Company's belief that its reserves are adequate.
Significant uncertainties continue to exist with regard to the ultimate outcome
and cost of Settlement II and the number and value of the opt-out claims. The
Company is unable at this time to determine whether additional reserves, which
could have a material adverse effect upon the financial condition, results of
operations and cash flows of the Company, may be necessary in the future.

  New Accounting Pronouncements

  In October 1995, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 123 "Accounting for Awards of
Stock-Based Compensation to Employees" (FAS 123), effective for fiscal years
beginning after December 15, 1995. FAS 123 establishes accounting and reporting
standards for stock-based employee compensation plans which include stock option
and stock purchase plans. FAS 123 provides employers a choice: adopt FAS 123
accounting standards for all stock compensation arrangements which requires the
recognition of compensation expense for the fair value of virtually all stock
compensation awards; or continue to account for stock options and other forms of
stock compensation under Accounting Principles Board Opinion No. 25 ("APB 25"),
the current accounting standard, while also providing the disclosure required
under FAS 123. The Company intends to continue accounting for its stock-based
compensation plans under APB 25. Therefore, the adoption of FAS 123 has no
effect on the Company's results of operations, financial position or cash flows.
With effect from September 30, 1996, the Company will provide, where material,
the disclosures required under FAS 123.

  In 1994, the American Institute of Certified Public Accountants issued
Statement of Position 94-6 "Disclosure of Certain Risks and Uncertainties" (SOP
94-6) effective for fiscal years ending after December 15, 1995. Pursuant to SOP
94-6, the Company has made certain disclosures as to risks and uncertainties and
the nature of the Company's operations and the use of estimates in the
preparation of its September 30, 1996 financial statements.

Management's Responsibility for Financial Statements

  Management is responsible for the preparation, integrity and objectivity of
the consolidated financial statements and other financial information presented
in this annual report. The accompanying consolidated financial statements were
prepared in accordance with generally accepted accounting principles, applying
certain estimates and judgments as required.

  The Company's internal controls are designed to provide reasonable assurance
as to the integrity and reliability of the financial statements and to
adequately safeguard, verify and maintain accountability of assets. Such
controls are based on established written policies and procedures and are
implemented by trained, skilled personnel with an appropriate segregation of
duties. These policies and procedures prescribe that the Company and all its
employees are to maintain the highest ethical standards and that its business
practices are to be conducted in a manner which is above reproach.

  Coopers & Lybrand L.L.P., independent accountants, are retained to audit the
Company's financial statements. Their accompanying report is based on audits
conducted in accordance with generally accepted auditing standards, which
includes the consideration of the Company's internal controls to establish a
basis for reliance thereon in determining the nature, timing and extent of audit
tests to be applied.

  The Board of Directors exercises its responsibility for these financial
statements through its Audit Committee, which consists entirely of independent
non-management Board members. The Audit Committee meets periodically with the
independent accountants, both privately and with management present, to review
accounting, auditing, internal controls and financial reporting matters.

  Report of Independent Accountants

  The Board of Directors and Shareholders of ACE Limited:

  We have audited the consolidated balance sheets of ACE Limited and
Subsidiaries as of September 30, 1996 and 1995, and the related consolidated
statements of operations, shareholders' equity, and cash flows for each of the
three years in the period ended September 30, 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

  In our opinion, the financial statements referred to above present fairly, in

                             Financial Statements

1  Organization

  ACE Limited ("ACE") is incorporated with limited liability under the Cayman
Islands Companies Law and maintains its principal business office in Bermuda.
The term "the Company" refers to ACE and its Bermuda-based subsidiaries,
excluding Methuen. The Company, through its Bermuda-based operating
subsidiaries, A.C.E. Insurance Company, Ltd. ("ACE Insurance"), Corporate
Officers & Directors Assurance Ltd. ("CODA") and Tempest Reinsurance Company
Limited ("Tempest"), provides insurance and reinsurance for a diverse group of
international clients.  In addition, the Company, through a corporate
subsidiary, provides funds at Lloyd's of London ("Lloyd's") to support
underwriting by syndicates managed by Methuen Underwriting Limited ("MUL"), a
majority owned subsidiary of the Company.

  On March 31, 1993, the Company completed an initial public offering of
21,390,000 Ordinary Shares (the "Offering").  All shares offered were sold by
existing shareholders and no proceeds of the Offering were received by the
Company.  On February 2, 1994, the Company completed a secondary offering of
8,000,000 Ordinary Shares (the "Secondary").  Again, all shares offered were
sold by existing shareholders and no proceeds of the Secondary were received by
the Company.

  On November 1, 1993, the Company acquired CODA, a Bermuda-based insurance
company, for a cash purchase price of $250 million and an additional contingent
cash payment of approximately $25 million which was made in December 1994 (the
"CODA Acquisition"). (See note 15 for pro forma financial information with
respect to the CODA Acquisition.)

  On March 27, 1996, the Company acquired a controlling interest in Methuen
Group Limited ("Methuen"), the holding company for MUL, a leading Lloyd's
managing agency (the "Methuen Acquisition").  The Company may acquire the
remaining 49 percent interest in Methuen during the years 1999 and 2000 through
various put and call arrangements, or earlier if mutually agreed.  MUL manages
six syndicates with a total underwriting capacity of (Pounds)366 million
(approximately $555 million) in 1996 (see note 2). This acquisition has been
recorded using the purchase method of accounting and accordingly, the
accompanying consolidated financial statements include the results of Methuen
since March 27, 1996, the date of acquisition.  Had the results of Methuen been
included commencing with operations in 1995, the reported results would not have
been materially affected.

  On July 1, 1996, the Company completed the acquisition of Tempest, a leading
Bermuda-based property catastrophe reinsurer (the "Tempest Acquisition"). Under
the terms of the Agreement and Plan of Amalgamation, Tempest shares outstanding
at the time of the acquisition were cancelled and converted into the right to
receive 13,333,247 Ordinary Shares of the Company. These shares were capitalized
at a value of $46 2/3 per share, which was determined in accordance with the
EITF 95-19 concensus that deals with the value of equity securities issued to
effect a purchase combination. In addition, options to acquire Tempest shares
were converted into 446,089 Company options at a total cost of $12.1 million.
The total value of the acquisition amounted to $638.7 million, which includes
the value of the shares and options issued as well as other transaction expenses
which amounted to $4.4 million. This acquisition has been recorded using the
purchase method of accounting and accordingly, the accompanying consolidated
financial statements include the results of Tempest since July 1, 1996, the date
of acquisition (see note 16 for pro forma financial information with respect to
the Tempest Acquisition).

  On September 25, 1996, the Company announced that it had signed a conditional
memorandum of understanding for the acquisition of Ockham Worldwide Holdings PLC
("Ockham Worldwide"), a wholly owned subsidiary of Ockham Holdings PLC
("Ockham").  Ockham Worldwide owns two Lloyd's managing agencies, Ockham Sturge
Aviation Agency Ltd. and Ockham Worldwide Agency Ltd.  Together these two
agencies manage seven syndicates with total underwriting capacity of (Pounds)349
million (approximately $524 million) in 1996.  Ockham Worldwide also owns a
Lloyd's corporate member which provides funds at Lloyd's to support underwriting
on these syndicates.  On November 7, 1996, the Company further announced that it
had signed a definitive agreement for the acquisition of Ockham Worldwide. The
acquisition is still conditional on final approval by Lloyd's and by Ockham
shareholders, as well as other customary closing conditions.  It is expected
that the acquisition will be completed prior to the end of November 1996.  The
Company's participation in the syndicates managed by Ockham Worldwide for the
1997 year of account is not likely to be material.

2  Operations

  a) Insurance operations

  The Company, through ACE Insurance and CODA, writes excess liability
insurance, directors and officers liability insurance, satellite insurance,
aviation insurance, excess property insurance and financial lines products.  At
September 30, 1996 approximately 

                                       33
<PAGE>
the
notes

                                      ACE
 
73 percent of the Company's written premiums came from North America with
approximately 20 percent coming from the United Kingdom and continental Europe
and approximately 7 percent from other countries.

  Two insurance brokers produced approximately 42 percent, 59 percent and 58
percent of the Company's insurance business for 1996, 1995 and 1994.

  The Company writes excess liability coverage on an occurrence first reported
stand alone form to a maximum of $200 million per occurrence and annual
aggregate. The minimum attachment point for this excess liability coverage is
generally $100 million; however, for certain classes of non-U.S. domiciled
insureds the Company allows a minimum attachment point of $50 million. For all
new and renewal business, effective on or after December 15, 1994, the Company
reduced the maximum limits offered for integrated occurrences from $200 million
to $100 million. The Company maintains excess of loss clash reinsurance to
protect it from losses arising from a single set of circumstances (occurrence)
covered by more than one excess liability insurance policy. The reinsurance
provides protection to a maximum of $150 million, and in the aggregate excess of
$225 million, for each and every loss occurrence involving three or more
insureds. Integrated occurrences are specifically excluded. There have been no
reinsurance recoveries to date on this reinsurance. Total clash reinsurance
premiums expensed were $7.9 million for fiscal 1996 and $7.8 million in fiscal
1995 and 1994.

  The Company offers excess directors and officers liability coverage with a
maximum policy limit of $50 million and a minimum attachment point, in most
circumstances, of $25 million. This coverage is frequently written on a
following form basis to underlying policies. The Company also provides up to $75
million of either primary, excess or excess and difference-in-conditions
directors and officers liability coverage for claims with respect to losses not
covered by corporate reimbursement. In all cases coverage is on a claims made
basis. The Company does not purchase reinsurance for its directors and officers
liability risks.

  The Company began satellite insurance operations in February 1994. Until
February 1996, the Company offered separate limits of up to $25 million per risk
for launch insurance, including ascent to orbit and/or initial testing, and up
to $25 million per risk for in-orbit insurance. This risk was fully retained by
the Company. Effective for all business written on or after February 15, 1996,
the Company has entered into a surplus treaty arrangement which provides for up
to $25 million of reinsurance for each risk. This reinsurance arrangement has
enabled the Company to raise the gross limits offered for satellite insurance to
$50 million per risk.

  In April 1995, the Company entered the aviation insurance market. The Company
currently offers limits of up to $100 million per insured, with no minimum
attachment point. The Company reduces its net exposure to approximately $50
million with a dedicated reinsurance program. Classes of business written
include aviation product liability, aircraft manufacturer's hull and liability,
airport liability, aviation refueling operations and associated aircraft
liability risks.

  From June 1995, the Company offers global excess property "all risk"
insurance, providing limits of up to a maximum of $50 million per occurrence
with a minimum attachment point of $25 million. Coverage includes such perils as
windstorm, earthquake and fire, as well as explosion. Consequential business
interruption coverage is also offered. In certain circumstances, the Company
uses reinsurance to establish the retained net limit per risk. In addition, the
Company has purchased catastrophe reinsurance to control the possible effects of
cumulative natural peril exposure.

  The Company's financial lines product group offers specifically designed
financial, insurance and reinsurance solutions to address complex risk
management problems. The programs offered typically have the following common
characteristics: multi-year contract terms, broad coverage that includes stable
capacity and pricing for the insured, aggregate policy limits and insured
participation in the results of their own loss experience. Each contract is
unique because it is tailored to the insurance or reinsurance needs, specific
loss history and financial strength of the insured. Premium volume, as well as
the number of contracts written, can vary significantly from period to period
due to the nature of the contracts being written. Profit margins may vary from
contract to contract depending on the amount of underwriting risk and investment
risk assumed on each contract.

  b) Reinsurance operations

  The Company, through Tempest, underwrites property catastrophe reinsurance on
a worldwide basis, emphasizing excess layer coverages, and has large aggregate
exposures to man-made and natural disasters. Tempest underwrites principally on
an excess of loss basis, with attachment points designed to minimize claims from
relatively high frequency and low severity events. For the ten month period
ended September 30, 1996, approximately 64 percent of Tempest's written premiums
came from the United States, approximately 13 percent came from United Kingdom,
6 percent from Australia and New Zealand and 16 percent from other countries.

  Two reinsurance brokers produced approximately 33 percent of Tempest's
reinsurance business for the ten month period ended September 30, 1996.

  The Company, through ACE Insurance, participates in the reinsurance of a
program referred to as "First Line" which provides financial guarantees required
by the U.S. Coast Guard to issue Certificates of Financial Responsibility, under
the Oil Pollution Act of 1990, to owners of vessels operating in U.S. waters.
The Company has purchased excess of loss reinsurance to limit its exposure in
this line.

  As discussed in note 2(a), the Company's financial lines product group also
offers reinsurance products.

  c) Lloyd's of London operations

  For the 1996 year of account, the Company, through a corporate subsidiary,
participates in the underwriting of the MUL syndicates by providing funds at
Lloyd's of (Pounds) 12.25 million (approximately $18 million), which was
primarily in the form of a letter of credit, supporting (Pounds) 24.5 million
(approximately $37 million) of underwriting capacity on syndicates managed by
MUL. The syndicates in which the Company participates underwrite aviation,
marine and non-marine risks. For the 1997 year of account, the Company has
agreed to provide funds at Lloyd's of

                                       34
<PAGE>
 
                                      ACE

approximately (Pounds) 62 million (approximately $93 million) to support up to
approximately (Pounds) 125 million (approximately $186 million) of underwriting
capacity by syndicates managed by MUL.

  3  Significant accounting policies

  a) Basis of presentation

  The accompanying consolidated financial statements have been prepared in
accordance with accounting principles generally accepted in the United States of
America ("GAAP") and include the accounts of the Company and its subsidiaries.
The Company records its proportionate share of the results of the Lloyd's
syndicates in which it participates. All significant intercompany balances and
transactions have been eliminated. Certain items in the prior year financial
statements have been reclassified to conform with the current year presentation.

  b) Investments

  The Company's investments are considered to be "available for sale" under the
definition included in the Financial Accounting Standard Board's ("FASB")
Statement of Financial Accounting Standards No. 115 "Accounting for Certain
Investments in Debt and Equity Securities." Except for "other investments", the
Company's investment portfolio is reported at fair value, being the quoted
market price of these securities provided by either independent pricing
services, or when such prices are not available, by reference to broker or
underwriter bid indications. Realized gains or losses on sales of investments
are determined on a first-in, first-out basis and include adjustments to the net
realizable value of investments for declines in value that are considered to be
other than temporary. Unrealized gains and losses are reported as a separate
component of shareholders' equity.

  Short-term investments comprise securities due to mature within one year of
date of issue. Other investments comprise a shareholding in a privately held
Bermuda-domiciled company for which there is no quoted market price. It is not
practicable to estimate the fair value of the investment and thus it is carried
at its original cost.

  The Company utilizes financial futures and option contracts and foreign
currency forward and option contracts for the purpose of managing certain
investment portfolio exposures (see note 7(a) for additional discussion of the
objectives and strategies employed). Futures contracts are not recognized as
assets or liabilities in the accompanying consolidated financial statements.
Changes in the market value of futures contracts produce daily cash flows, which
are included in net realized gains or losses on investments in the statements of
operations. Collateral held by brokers equal to a percentage of the total value
of open futures contracts is included in short-term investments.

  Option contracts that are designated as hedges of securities are marked-to-
market. Unrealized gains and losses on forward currency and option contracts
which are designated as specific hedges are recognized in the financial
statements as a component of shareholders' equity. Gains and losses resulting
from currency fluctuations on transactions which are not designated as specific
hedges against any single security or group of securities are recognized as a
component of income in the period in which the fluctuations occur. Premiums paid
or received on option contracts that have expired, been closed out or exercised,
are recognized as realized gains and losses on investments in the statements of
operations.

  Net investment income includes interest and dividend income together with
amortization of market premiums and discounts and is net of investment
management and custody fees and loan expense. For mortgage-backed securities,
and any other holdings for which there is a prepayment risk, prepayment
assumptions are evaluated and revised as necessary. Any adjustments required due
to the resultant change in effective yields and maturities are recognized in
current income. Additionally, in 1994 and the first quarter of 1995,
amortization resulting from the discounting of balances outstanding on the
acquisition of CODA have been recorded against investment income.

  c) Premiums

  Premiums written are recognized as revenues when due. For multi-year policies
written which are payable in annual installments, due to the ability of the
insured/reinsured to commute or cancel coverage within the term of the policy,
only the annual premium is included as written at policy inception. The
remaining annual premiums are included as written at each successive anniversary
date within the multi-year term.

  Premiums written are primarily earned on a daily pro rata basis over the terms
of the policies to which they relate. Accordingly, unearned premiums represent
the portion of premiums written which is applicable to the unexpired portion of
the policies in force. Premium estimates for retrospectively rated policies are
recognized within the periods in which the related losses are incurred.

  Property catastrophe reinsurance premiums written are estimated based on
information provided by ceding companies. The information used in establishing
these estimates is reviewed and subsequent adjustments are recorded in the
period in which they are determined. These premiums are earned over the terms of
the related reinsurance contracts.

  d) Acquisition costs

  Acquisition costs, consisting primarily of commissions, are deferred and
amortized over the period in which the related premiums are earned. Deferred
acquisition costs are reviewed to determine that they do not exceed recoverable
amounts after considering investment income.

  e) Losses and loss expenses

  A reserve is established for the estimated unpaid losses and loss expenses of
the Company under the terms of, and with respect to, its policies and
agreements. The methods of determining such estimates and establishing the
resulting reserve are reviewed continuously and any adjustments are reflected in
operations in the period in which they become known. Future developments may
result in losses and loss expenses significantly

                                      35
<PAGE>

the
notes
                                      ACE

greater or less than the reserve provided.

  f) Goodwill

  The Company amortizes goodwill recorded in connection with its business
combinations on a straight-line basis over the lesser of the expected life of
the related operations acquired or forty years.  Amortization of goodwill
amounting to $1,269,000 with respect to the Tempest Acquisition is included in
administrative expenses in the statements of operations for the year ended
September 30, 1996.

  g) Translation of foreign currencies

  Financial statements of subsidiaries expressed in foreign currencies are
translated into U.S. dollars in accordance with Statement of Financial
Accounting Standards No. 52 "Foreign Currency Translation" ("FAS 52").  Under
FAS 52, functional currency assets and liabilities are translated into U.S.
dollars generally using period end rates of exchange and the related translation
adjustments are recorded as a separate component of shareholders' equity.
Functional currencies are generally the currencies of the local operating
environment.  Statements of operations amounts expressed in functional
currencies are translated using average exchange rates.  Transaction gains and
losses resulting from foreign currency transactions are also recorded in income
currently.

  h) Accounting estimates

  The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period.  The Company's principal estimates include
property and casualty loss and loss expense reserves and estimated premiums for
situations where the Company has not received ceding company reports.  Actual
results may differ from these estimates.

  i) Earnings (loss) per share

  Earnings (loss) per share are computed using net income (loss) divided by the
weighted average number of Ordinary Shares outstanding and, if dilutive, shares
issuable under outstanding options.  There is no material difference between
primary and fully diluted earnings (loss) per share.

  j) Cash flow information

  Purchases and sales or maturities of short-term investments are recorded net
for purposes of the statements of cash flows and are included with fixed
maturities.

  k) Accounting pronouncements

  In October 1995, FASB issued Statement of Financial Accounting Standards No.
123 "Accounting for Awards of Stock-Based Compensation to Employees" ("FAS
123"), effective for fiscal years beginning after December 15, 1995.  FAS 123
establishes accounting and reporting standards for stock-based employee
compensation plans which include stock option and stock purchase plans.  FAS 123
provides employers a choice: adopt FAS 123 accounting standards for all stock
compensation arrangements which requires the recognition of compensation expense
for the fair value of virtually all stock compensation awards; or continue to
account for stock options and other forms of stock compensation under Accounting
Principles Board Opinion No. 25 ("APB 25"), the current accounting standard,
while also providing the disclosure required under FAS 123.  The Company intends
to continue accounting for its stock-based compensation plans under APB 25.
Therefore, the adoption of FAS 123 has no effect on the Company's results of
operations, financial position or cash flows. With effect from September 30,
1996, the Company will provide, where material, the disclosures required under
FAS 123. For September 30, 1996, the effect of FAS 123 is not material to the
Company.

  In 1994, the American Institute of Certified Public Accountants issued
Statement of Position 94-6 "Disclosure of Certain Risks and Uncertainties" (SOP
94-6) effective for fiscal years ending after December 15, 1995.  Pursuant to
SOP 94-6, the Company has made certain disclosures as to risks and uncertainties
and the nature of the Company's operations and the use of estimates in the
preparation of these financial statements.

</TABLE>

  Mortgage-backed securities issued by U.S. government agencies are combined
with all other mortgage derivatives held and are included in the category
"mortgage-backed securities". Approximately 72 percent of the total mortgage
holdings at September 30, 1996 and 74 percent at September 30, 1995 are
represented by investments in GNMA, FNMA and FHLMC bonds. The remainder of the
mortgage exposure consists of CMO's (Collateralized Mortgage Obligations) and
non-government mortgage-backed securities, the majority of which provide a
planned structure for principal and interest payments and carry a "AAA" rating
by the major credit rating agencies.

  Fixed maturities at September 30, 1996, by contractual maturity, are shown
below. Expected maturities could differ from contractual maturities because
borrowers may have the right to call or prepay obligations, with or without call
or prepayment penalties.

  e) Other investments

  Other investments comprise 124,526 shares of cumulative perpetual preferred
stock held in Centre Reinsurance Holdings Limited ("Centre Re"), a privately
held Bermuda-domiciled reinsurer specializing in finite-risk reinsurance. The
investment in Centre Re is recorded at cost of $12,453,000 and management is of
the opinion that the fair value of this investment is at least equal to the cost
of the investment. The cumulative cash dividend rate is currently 10 percent and
is adjusted every ten years based on the prevailing 10-year U.S. Treasury note
rate plus 3.65 percent. Dividends are paid twice a year and there are no
cumulative dividends in arrears. There are certain restrictions regarding the
sale or redemption of the above preferred stock, none of which in the Company's
opinion would impair the carrying value of the investment. In fiscal 1994, the
Company sold its investment in the voting common shares of Centre Re, and
recognized a gain of approximately $58 million which is included in net realized
gains on investments in the statements of operations.

5  Losses and loss expenses

  The reserve for unpaid losses and loss expenses represents estimated
ultimate losses and loss expenses less paid losses and loss expenses and is
comprised of the following at September 30, 1996 and 1995:

</TABLE>

   The Company uses statistical and actuarial methods to reasonably estimate
ultimate expected losses and loss expenses using the Company's loss development
history, data obtained from underwriting applications, actuarial evaluations
and, in the case of excess liability reserves, research of large liability
losses. In many cases, significant periods of time, ranging up to several years
or more, may lapse between the occurrence of an insured loss, the reporting of
the loss to the Company and the settlement of the Company's liability for the
loss. During the loss settlement period, additional facts regarding individual
claims and trends usually will become known. As these become apparent, case
reserves may be adjusted by allocation from IBNR loss reserves without any
change in the overall reserve. In addition, application of the statistical and
actuarial methods may require the adjustment of the overall reserves from time
to time.

   The reconciliation of unpaid losses and loss expenses for the years ended
September 30, 1996, 1995 and 1994 is as follows:

</TABLE>

   A number of the Company's insureds have given notice of claims relating to
breast implants or components or raw material thereof that had been produced
and/or sold by such insureds. Lawsuits including class actions, involving
thousands of implant recipients have been filed in both state and federal courts
throughout the United States. Most of the federal cases have been consolidated
pursuant to the rules for Multidistrict Litigation ("MDL") to a Federal District
Court in Alabama.

   On April 1, 1994, the judge presiding over the MDL proceeding gave
preliminary approval to a global settlement agreement in the approximate amount
of $4.2 billion and conditional certification to a settlement class
("Global I").

   On May 15, 1995, the Dow Corning Corporation, a significant participant in
the Global I settlement, filed for protection under Chapter 11 of the U.S.
Bankruptcy Code.

   As of June 1, 1995, over 440,000 registrations were received by the Global
I Claims Administrator. Approximately 248,500 of these were filed by domestic
class members by the September 16, 1994 deadline for making claims under the
Current Disease Compensation Program. Based on an analysis of about 3,000 of
these registrations, the judge concluded that a severe racheting (or reduction)
of the settlement amounts shown in the notice of

                                      39

<PAGE>

                                  [ACE LOGO]

settlement would occur if current claims were evaluated under the existing
criteria and if funding of the Current Disease Compensation Program remained at
the $1.2 billion level.

  Because of the anticipated racheting of benefit amounts and the defendants'
right to withdraw under the Global I settlement, the judge entered an order on
October 9, 1995 declaring that class members had new opt-out rights and that in
general class members and their attorneys should not expect to receive any
benefits under Global I.

  On October 1, 1995, negotiators for three of the major defendants agreed on
the essential elements of a revised individual settlement plan for domestic
class members with at least one implant from any of those manufacturers
("Settlement II").  In general, under Settlement II, the amounts payable to
individual participants, and the manufacturers' obligations to make those
payments, would not be affected by the number of class members electing to opt
out from the new plan.  Also, in general, the compensation would be fixed rather
than subject to potential further racheting, and the manufacturers would not
have a right to walk away because of the amount of claims payable.  Finally,
each defendant agreed to be responsible only for cases in which its implant was
identified, and not for a percentage of all claims.

  By November 13, 1995, Settlement II was approved by the three major
defendants.  In addition, two other defendants became part of Settlement II,
although certain of their settlement terms are different and more restricted
than the plan offered by the original three defendants.

  At June 30, 1994, the Company increased its then existing reserves relating to
breast implant claims.  Although the reserve increase was partially satisfied by
an allocation from existing IBNR, it also required an increase in the Company's
total reserve for unpaid losses and loss expenses at June 30, 1994 of $200
million.  The increase in reserves was based on information made available in
conjunction with Global I (including information relating to opt-outs) and
information made available from the Company's insureds and was predicated upon
an allocation between coverage provided before and after the end of 1985 (when
the Company commenced underwriting operations).  No additional reserves relating
to breast implant claims have been added since June 30, 1994.

  The Company believes that its reserves for unpaid losses and loss expenses
including those arising from breast implant claims are adequate as of September
30, 1996.  The Company continually evaluates its reserves in light of developing
information and in light of discussions and negotiations with its insureds. In
August 1996, the Company settled with one of its policyholders, a breast implant
manufacturer, for a sum of money to be paid out over a number of years in the
future. The settlement is consistent with the Company's belief that its reserves
are adequate.  Significant uncertainties continue to exist with regard to the
ultimate outcome and cost of Settlement II and the number and value of the opt-
out claims. The Company is unable at this time to determine whether additional
reserves, which could have a material adverse effect upon the financial
condition, results of operations and cash flows of the Company, may be necessary
in the future.

6  Reinsurance

  The Company reinsures certain risks to limit its exposure to catastrophic
risks.  Although reinsurance agreements contractually obligate the Company's
reinsurers to reimburse it for the agreed upon portion of its gross paid losses,
they do not discharge the primary liability of the Company.  The Company
evaluates the financial condition of its reinsurers through an internal
reinsurance committee consisting of certain members of the Company's senior
management.  No single reinsurer is a material reinsurer to the Company nor is
the Company's business dependent on any reinsurance contract.  The statements of
operations amounts for premiums written and premiums earned are net of
reinsurance.  Direct, assumed and ceded amounts for these items for the years
ended September 30, 1996, 1995 and 1994 are as follows:

  7  Commitments and contingencies

  a) Financial instruments with off-balance sheet risk

  The Company's investment guidelines permit, subject to specific approval,
investments in derivative instruments such as futures, options and foreign
currency forward contracts for purposes other than trading. Their use is limited
to yield enhancement, duration management, foreign currency exposure management
or to obtain an exposure to a particular financial market.

  (i) Foreign currency exposure management

  The Company uses foreign currency forward and option contracts to minimize the
effect of fluctuating foreign currencies on the value of non-U.S. dollar
securities currently held in the portfolio. Approximately $255 million is
invested in non-U.S. dollar fixed maturity and equity securities. The forward
currency contracts purchased are not specifically identifiable against any
single security or group of securities denominated in those currencies and
therefore do not qualify as hedges for financial reporting purposes. All
contract gains and losses, realized and unrealized, are reflected in the
statements of operations. At September 30, 1996, no foreign currency forward or
option contract had a maturity of more than four months.

  The table below summarizes the notional amounts, the current fair values and
the unrealized gain or loss of the Company's foreign currency forward and option
contracts as at September 30, 1996.
<TABLE>
<CAPTION>

                                      ------------------------------------------
 <S>                                        <C>            <C>        <C>
                                                      (in thousands)
  Forward contracts                          $(1,246)      $(1,309)     $ 63
  Foreign currency option contracts            8,647           290       390
</TABLE>

  The fair value of the forward contracts represents the estimated cost to the
Company at September 30, 1996 of obtaining the specified currency to meet the
obligation of the contracts. The unrealized gain is a measure of the net
exposure to the Company of its use of forward contracts after any netting
agreements given current rates of exchange. The fair value of the options
represents the market price of the options at September 30, 1996. The unrealized
gains represents the difference between the fair value and the premium paid.

  The credit risk associated with the above derivative financial instruments
relates to the potential for non-performance by counterparties. Non-performance
is not anticipated; however in order to minimize the risk of loss, management
monitors the creditworthiness of its counterparties. For forward contracts, the
counterparties are principally banks which must meet certain criteria according
to the Company's investment guidelines.

  (ii) Duration management and market exposure

  Futures

  A portion of the Company's investment portfolio is managed as a synthetic
equity fund, whereby S&P 500 index futures contracts are held in an amount equal
to the market value of an underlying portfolio comprised of short-term
investments and fixed maturities. This creates an equity market exposure equal
in value to the total amount of funds invested in this strategy. Each index
futures contract held by the Company is rolled over quarterly into a new
contract with a later maturity, thereby maintaining a constant equity market
exposure. The value of this fund was $305 million and $205 million at September
30, 1996 and 1995, respectively.

  Exchange traded bond and note futures contracts may be used in fixed maturity
portfolios as substitutes for ownership of the physical bonds and notes without
significantly increasing the risk in the portfolio. Investments in financial
futures contracts may be made only to the extent that there are assets under
management, not otherwise committed.

  Futures contracts give the holder the right and obligation to participate in
market movements, determined by the index or underlying security on which the
futures contract is based. Settlement is made daily in cash by an amount equal
to the change in value of the futures contract times a multiplier that scales
the size of the contract. The contract amounts of $478 million and $366 million
reflect the net extent of involvement the Company had in these financial
instruments at September 30, 1996 and 1995, respectively.

  Options

  Option contracts may be used in the portfolio as protection against unexpected
shifts in interest rates, which would thereby affect the duration of the fixed
maturity portfolio. By using options in the portfolio, the overall interest rate
sensitivity of the account can be reduced. An option contract conveys to the
holder the right, but not the obligation, to purchase or sell a specified amount
or value of an underlying security at a fixed price. The price of an option is
influenced by the underlying security, expected volatility, time to expiration
and supply and demand.

  For long option positions, the maximum loss is the premium paid for the
option. To minimize the risk of non-performance, all brokers and dealers used as
counterparties must be approved. Additional performance assurance is required
where deemed necessary. The maximum credit exposure is represented by the fair
value of the options held. For short option positions, the potential loss is the
same as having taken a position in the underlying security. Short call options
are backed in the portfolio with the underlying, or highly correlated,
securities and short put options are to be backed by uncommitted cash for the 
in-the-money portion. Summarized below are the notional amounts, the current
fair values and the unrealized gains or losses of the options in the portfolio
as at September 30, 1996.

</TABLE>

  The fair value of the options represents the market price of the options at
September 30, 1996. The unrealized gains or losses represent the difference
between the fair value and the premium paid (received). The notional amounts
summarized in the above tables are not representative of amounts exchanged by
parties and, therefore, do not measure the exposure to the Company of its use of
derivatives.

  b) Concentrations of credit risk

  The investment portfolio is managed following prudent standards of
diversification. Specific provisions limit the allowable holdings of a single
issue and issuers. All fixed maturity securities held must have an investment
grade rating. The Company believes that there are no significant concentrations
of credit risk associated with its investments.

  c) Letters of credit

  Tempest is not an admitted reinsurer in the United States. Accordingly, the
terms of certain reinsurance contracts require Tempest to provide letters of
credit ("LOCs") to Tempest's clients in respect of reported claims. Tempest has
a facility for the issuance of LOCs of up to $20 million. At September 30, 1996,
LOCs outstanding amounted to $8.4 million. Investments with a market value of
$15.4 million were pledged as collateral for these LOCs.

  d) Lease commitments

  The Company rents office space in The ACE Building in Hamilton, Bermuda under
a lease which expires in 2000, with one five year renewal option. The ACE
Building is 40 percent owned by the Company through a joint venture agreement
dated July 1, 1987. During 1994, the Company financed the cost of an addition to
The ACE Building and entered into a supplemental lease for the additional space
for 14 years effective October 1, 1994. The cost of the addition is being
amortized as rent expense over the period of the lease. Tempest also leases
office space in Hamilton, Bermuda under a non-cancelable lease expiring in 1998
with a three year renewal option. Methuen leases office space in London, England
under a lease that expires in 2012. Methuen also leases an office in the 1986
Lloyd's Building in London. Total rent expense was approximately $2.3 million in
1996, $1.5 million in 1995 and $1.0 million in 1994. Future minimum rental
commitments under the leases for office space occupied are expected to be
approximately $2.9 million per annum.

major international banks, led by Morgan Guaranty Trust Company of New York
which provides for unsecured borrowings up to an aggregate amount of $150
million.  The line of credit agreement requires the Company to maintain
consolidated tangible net worth of not less than $950 million.

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

10  Employee benefit plans

  a)  Pension plans

  The Company has defined contribution pension plans which are non-contributory
and cover all full-time employees.  Contributions are based on a percentage of
eligible compensation. Pension costs amounted to $1,741,000, $1,206,000, and
$911,000 for 1996, 1995 and 1994, respectively.

  b) Options and Stock Appreciation Rights

  On February 9, 1996, shareholders of the Company approved the ACE Limited 1995
Long-Term Incentive Plan (the "Incentive Plan") which incorporates stock
options, stock appreciation rights, restricted stock awards and stock purchase
programs.  There are 2,300,000 Ordinary Shares of the Company available for
award under this Incentive Plan.  This Incentive Plan superseded and replaced
the existing Equity Linked Incentive Plan, which incorporated both a Stock
Appreciation Rights Plan ("SAR Plan") and a Stock Option Plan ("Option Plan")
which will continue to run off.  Stock options granted under the Incentive Plan
may be exercised for Ordinary Shares of the Company upon vesting.  Under the
Incentive Plan, generally, options expire ten years after the award date and
vest in equal portions over three years.  During 1996, in addition to the
446,089 options issued with respect to the Tempest acquisition, 409,200 options
were issued at an average exercise price of $37.41 (see note 8 (e)).

  Under the Option Plan, generally, options expire ten years after the award
date and are subject to a vesting period of four years.  During 1995 and 1994,
236,000 and 122,500 options were granted at average exercise prices of $24.35
and $29.56, respectively (see note 8(e)).

  Of the outstanding options at September 30, 1996 35,000 were vested.  In
addition to the Option Plan, the Company entered into an Option and Restricted
Share Agreement and Plan in connection with the employment of its Chairman,
President and Chief Executive Officer whereby during the year ended September
30, 1995, he was awarded 300,000 stock options at an exercise

the

                                      ACE
 
price of $22.63 which may be exercised for Ordinary Shares. These options expire
ten years after the award date and vest at various dates up to September 30,
1999. The Chairman also received 100,000 restricted stock under this agreement
(see note 10(d)).

  The SAR Plan entitles participants the right to receive cash equal to the
appreciation in value, as provided for in the Plan, of the rights represented by
the grant.  Rights vest over a period of up to six years from the date of grant.
Participants are entitled to receive cash payments equal to the amount of
dividends paid on an equivalent number of shares.  During 1992 and 1993, 392,800
rights were awarded at prices of between $17.28 and $21.91.  As at September 30,
1996, 326,400 rights remained outstanding.  During 1996, 18,667 rights were
exercised and 27,733 rights were forfeited.  During 1995, 20,000 rights were
forfeited.  Compensation expense is accrued and recorded based on the change in
the value of the stock appreciation rights during the year and the applicable
vesting period.  In 1996 and 1995, compensation expense of $6,023,000 and
$2,465,000 was recorded, respectively.  In 1994, a reduction of compensation
expense of $1,402,000 was recorded as a result of depreciation in the value of
the rights.

  c) Employee Stock Purchase Plan

  On February 9, 1996, shareholders of the Company approved the ACE Limited
Employee Stock Purchase Plan.  Participation in the plan is available to all
eligible employees.  Maximum annual purchases by participants are limited to the
number of whole shares that can be purchased by an amount equal to 10 percent of
the participant's compensation or $25,000, whichever is less.  Participants may
purchase shares at a purchase price equal to 85 percent of the closing market
price of the Company's shares on the last day of each subscription period.
Subscription periods currently run for six months with the first period closing
on September 30, 1996.  With respect to the subscription period ending on
September 30, 1996, 4,368 shares were subscribed for, resulting in an immaterial
expense to the Company.

  d)  Restricted stock awards

  During 1996, 9,000 restricted Ordinary Shares were awarded to an officer of
the Company.  These shares vest at various dates up to July 1999.  Also, during
1996, 6,734 restricted Ordinary Shares were awarded to outside directors of the
Company under the terms of the 1995 Outside Directors Plan which was approved by
the shareholders of the Company on February 9, 1996.  These shares vest in
February 1997.  All unvested restricted Ordinary Shares issued to directors
prior to approval of the Plan were canceled upon approval of the Plan.
Subsequently, two directors resigned resulting in the forfeiture of their
restricted Ordinary Shares awards.

  During 1995, 102,400 restricted Ordinary Shares were awarded principally to
the Chairman and four directors of the Company.  The Chairman's award vests at
various dates up to September 30, 1999.  During 1994, 17,600 restricted Ordinary
Shares were awarded to an officer and directors of the Company. The officer
subsequently resigned from the Company in December 1995 and all unvested awards
were forfeited.  All restricted stock awards contain restrictions relating to,
among other things, transferability and forfeiture under certain circumstances.

  At the time of grant the market value of the shares awarded under these grants
is recorded as unearned stock grant compensation and is presented as a separate
component of shareholders' equity.  The unearned compensation is charged to
operations over the vesting period.

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

11  Related party transactions

  Included in net premiums written are amounts related to policies held by
shareholders of the Company of approximately $31 million, $43 million and $45
million for 1996, 1995 and 1994, respectively.

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

12  Taxation

  Under current Bermuda law, the Company is not required to pay any taxes on its
income or capital gains.  The Company has received an undertaking from the
Minister of Finance that, in the event of any taxes being imposed, the Company
will be exempt from taxation in Bermuda until March 2016.

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

13  Statutory financial data

  Under the Bermuda Insurance Act 1978, as amended by the Insurance Amendment
Act 1995 and Related Regulations the Company's Bermuda-based insurance and
reinsurance subsidiaries (the "Bermuda subsidiaries") are required to file an
annual Statutory Financial Return and Statutory Financial Statements and to
maintain certain measures of solvency and liquidity during each year.  Statutory
capital and surplus of the Bermuda subsidiaries was $1,885 million, $1,327
million and $914 million at September 30, 1996, 1995 and 1994 and statutory net
income was $301 million and $249 million for 1996 and 1995 respectively, and a
net loss of $123 million for 1994.  Statutory capital and surplus and statutory
net income include the results of Tempest from July 1, 1996 and CODA from
November 1, 1993, the dates of acquisition for each company.  The principal
difference between statutory capital and surplus and statutory net income of
these Bermuda subsidiaries and shareholders' equity and net income as reported
in conformity with GAAP relates to deferred acquisition costs of the
subsidiaries, goodwill, and assets and financial activity of the parent company.

  There are no statutory restrictions on the payment of dividends from retained
earnings by any of the Bermuda subsidiaries as the minimum statutory capital and
surplus requirements are satisfied by the share capital and additional paid-in
capital of each of the Bermuda subsidiaries.

                     TAXATION OF ACE AND ITS SHAREHOLDERS

     The following summary of (i) the taxation of ACE and its subsidiaries and
(ii) the taxation of ACE shareholders is based upon current law.  Legislative,
judicial or administrative changes may be forthcoming that could be retroactive
and could affect this summary. The tax treatment of any particular shareholder
may vary depending on such shareholder's particular tax situation or status. The
following summary is for general information only and does not purport to be a
complete analysis or listing of all tax considerations that might be applicable
to ACE and its subsidiaries or a holder of ACE Ordinary Shares, including
persons who may be
<PAGE>
 
subject to special tax rules (e.g. tax exempt entities or dealers in securities)
or shareholders who are not U.S. persons.  A U.S. person who holds ACE Ordinary 
Shares as capital assets will be referred to herein as a "U.S. ACE Shareholder."
Each prospective shareholder is urged to consult his or its own tax advisors as 
to the particular tax consequences to such shareholder of owning ACE Ordinary 
Shares.

Taxation of ACE and its Subsidiaries

     Bermuda.  CODA and ACE Insurance have received from the Minister of Finance
of Bermuda an assurance under The Exempted Undertakings Tax Protection Act, 1966
of Bermuda, to the effect that in the event of there being enacted in Bermuda
any legislation imposing tax computed on profits or income, or computed on any
capital asset, gain or appreciation, or any tax in the nature of estate duty or
inheritance tax, then the imposition of any such tax shall not be applicable to
CODA or ACE Insurance or to any of their operations or the shares, debentures or
other obligations of CODA or ACE Insurance until March 28, 2016.  This assurance
does not prevent the application of any such tax or duty to such persons as are
ordinarily resident in Bermuda, nor does it prevent the application of any tax
payable in accordance with the provisions of the Land Tax Act 1967 of Bermuda or
otherwise payable in relation to the property leased to CODA or ACE Insurance.
ACE, as a permit company under the Companies Act 1981 of Bermuda (the "Bermuda
Act"), has received similar assurances which are effective until March 28, 2016.
CODA and ACE Insurance, under current rates, pay annual Bermuda government and
business fees in the aggregate of BD$4,515 and BD$7,875, respectively.  ACE is
required to pay certain annual Bermuda government fees.  Under current rates, 
ACE pays a fixed annual fee of BD$1,680.  In addition, all entities employing
individuals in Bermuda are required to pay a payroll tax to the Bermuda
Government.  For the fiscal year ended September 30, 1996, ACE paid 
approximately $776,000 in payroll tax. Currently there is no Bermuda 
withholding tax on dividends paid by CODA or ACE Insurance.

     Cayman Islands.  Under current Cayman Islands law, ACE is not obligated to 
pay any taxes in the Cayman Islands on its income or gains.  ACE has received an
undertaking from the Governor-in-Council of the Cayman Islands pursuant to the 
provisions of the Tax Concessions Law, as amended, that until the year 2005 (i)
no subsequently enacted law imposing any tax on profits, income, gains or
appreciations shall apply to ACE and (ii) no such tax and no tax in the nature
of an estate duty or an inheritance tax shall be payable on any shares,
debentures or other obligations of ACE. The Cayman Islands currently imposes
stamp duties on certain categories of documents; however, the current operations
of ACE do not involve the payment of stamp duties in any material amount. The
Cayman Islands currently imposes an annual corporate fee upon all exempted
companies; at current rates ACE pays fees of approximately $1,750 per annum.

     United Kingdom.  Methuen is subject to United Kingdom corporation tax and 
value added tax.  ACE's corporate subsidiary which has acquired a 51% interest 
in Methuen and ACE's corporate subsidiary that is a Lloyd's corporate member 
participating in the Methuen syndicates are also subject to United Kingdom 
corporation tax and value added tax.  Although ACE has a representative office
in London, ACE has been advised that it is not deemed to be doing insurance
business in the United Kingdom and therefore is subject only to minimal tax in
the United Kingdom.

     United States.  Except as provided below with respect to ACE's corporate 
subsidiary that is a Lloyd's corporate member, ACE and its subsidiaries do not 
conduct business within the United States and thus are not subject to net income
tax imposed by the United States.  However, because definitive identification of
activities which constitute being engaged in a trade or business in the United 
States is not provided by the Code, regulations or court decisions, there can be
no assurance that the IRS will not contend successfully that ACE or one or more 
of its subsidiaries is engaged in a trade or business in the United States.  A 
foreign corporation deemed to be so engaged would be subject to U.S. income tax,
as well as the branch profits tax, on its income which is treated as effectively
connected with the conduct of that trade or business unless the corporation is 
entitled to relief under the permanent establishment provision of the Bermuda 
Treaty, as discussed below.  Such income tax, if imposed, would be based on 
effectively connected income computed in a manner generally analogous to that 
applied to the income of a domestic corporation, except that a foreign 
corporation can anticipate an allowance of deductions and credits only if it 
files a U.S. income tax return.  Under regulations, the foreign corporation 
would be entitled to deductions and credits only if the return is filed timely 
under rules set forth
<PAGE>
 
therein. ACE and its subsidiaries have in the past and expect to continue filing
protective tax returns to ensure that it and its subsidiaries would be entitled 
to deductions and credits if they are considered to be engaged in a U.S. trade 
or business. The highest federal tax rates currently are 35% for a corporation's
effectively connected income and 30% for the branch profits tax. The branch 
profits tax is imposed on effectively connected net income after subtracting the
regular corporate tax and making certain other adjustments and on interest paid 
or deemed paid from the U.S. branch to persons outside the United States. 
Pursuant to a Closing Agreement between Lloyd's and the IRS, ACE's corporate 
subsidiary that is a Lloyd's corporate member is treated as engaged in business 
in the United States and subject to net income tax in the United States on its 
U.S. source income.

     Under the Bermuda Treaty, CODA and ACE Insurance are subject to U.S. income
tax on any income found to be effectively connected with a U.S. trade or
business only if that trade or business is conducted through a permanent
establishment in the United States. No regulations interpreting the Bermuda
Treaty have been issued. While there can be no assurances, ACE does not believe
CODA or ACE Insurance has a permanent establishment in the United States.
Neither CODA nor ACE Insurance would be entitled to the benefits of the Bermuda
Treaty if (i) less than 50% of such subsidiary's stock were beneficially owned,
directly or indirectly, by Bermuda residents or U.S. citizens or residents, or
(ii) such subsidiary's income were used in substantial part to make
disproportionate distributions to, or to meet certain liabilities of, persons
who are not Bermuda residents or U.S. citizens or residents. While there can be
no assurances, ACE believes that no exception to Bermuda Treaty benefits will
apply after the Amalgamation.

     Foreign corporations not engaged in a trade or business in the United 
States are nonetheless subject to U.S. income tax on certain "fixed or 
determinable annual or periodic gains, profits and income" derived from sources 
within the United States as enumerated in Section 881(a) of the Code (such as 
dividends and certain interest on investments). The amount of such taxes paid by
ACE has not exceeded $1.7 million in any fiscal year.

     Effect of the Amalgamation. ACE believes that the Amalgamation will not 
cause ACE or its existing subsidiaries to be subject to tax in the Cayman 
Islands, Bermuda or the United States (except to the very limited extent noted 
above that they are currently subject to tax in those jurisdictions), and it is 
expected that the ACE Reinsurance Subsidiary will be taxed in a manner similar 
to ACE's other subsidiaries. Accordingly, the foregoing description of the tax 
treatment of ACE and its operating subsidiaries by Bermuda, the Cayman Islands, 
the United Kingdom and the United States should remain unchanged after the 
Effective Time and should, where applicable, apply equally to the ACE 
Reinsurance Subsidiary.

Taxation of ACE Shareholders

     Cayman Islands. Dividends paid by ACE are not subject to Cayman Islands 
withholding tax.

     Bermuda. Under current Bermuda law, there is no Bermuda income tax, 
withholding tax, capital gains tax, capital transfer tax, estate duty or 
inheritance tax payable by the respective shareholders of ACE with respect to an
investment in ACE Ordinary Shares.

     United States--Taxation of dividends. Subject to the discussion below 
relating to the potential application of the "controlled foreign corporation" 
and "passive foreign investment company" rules, cash distributions made with 
respect to ACE Ordinary Shares will constitute dividends for U.S. federal income
tax purposes to the extent paid out of current or accumulated E&P of ACE. U.S. 
ACE Shareholders generally will be subject to U.S. federal income tax on the 
receipt of such dividends. Generally, such dividends will not be eligible for 
the corporate dividends received deduction. To the extent that a distribution 
exceeds E&P, it will be treated first as a return of the U.S. ACE Shareholder's 
basis to the extent thereof, and then as gain from the sale of a capital asset.

     United States--Classification as a controlled foreign corporation. Under 
Section 951(a) of the Code, each "U.S. 10% shareholder" (as defined below) that,
on the last day of foreign corporation's taxable year, owns, directly or 
indirectly through a foreign entity, shares of a foreign corporation that is a 
"controlled foreign


                                                                              6/
<PAGE>
 
corporation" ("CFC") for an uninterrupted period of 30 days or more during any 
taxable year must include in its gross income for U.S. federal income tax 
purposes its pro rata share of the CFC's "subpart F income" for such year, even 
if the subpart F income is not distributed. In addition, the U.S. 10% 
shareholders of a CFC may be deemed to receive taxable distributions to the 
extent the CFC increases the amount of its earnings that are invested in certain
specified types of U.S. property or if the CFC holds "excess passive assets," as
defined in Section 956A of the Code. "Subpart F income" includes, inter alia, 
(i) "foreign personal holding company income", such as interest, dividends, and 
other types of passive investment income and (ii) "insurance income," which is 
defined to include any income (including underwriting and investment income) 
that is attributable to the issuing (or reinsuring) of any insurance or annuity 
contract in connection with property in, liability arising out of activity in, 
or in connection with the lives or health of residents of, a country other than 
the country under the laws of which the CFC is created or organized, and which 
(subject to certain modifications) would be taxed under the insurance company 
provision of the Code if such income were the income of a domestic insurance 
company ("Subpart F Insurance Income"). However, Subpart F income does not 
include any income from sources within the U.S. which is effectively connected 
with the conduct of a trade or business within the U.S. and not exempted or 
subject to a reduced rate of tax by applicable treaty. Therefore, all of ACE's 
income, and all income of ACE's operating subsidiaries that is not attributable 
to a permanent establishment in the U.S., is expected to be Subpart F income.

     Under Section 951(b) of the Code, any U.S. Person who owns, directly or 
indirectly through foreign entities, or is considered to own (by application of 
the rules of constructive ownership set forth in Code Section 958(b), generally 
applying to family members, partnerships, estates, trusts or 10% controlled 
corporations) 10% or more of the total combined voting power of all classes of 
stock of a foreign corporation will be considered to be a "U.S. 10% 
shareholder." In general, a foreign corporation is treated as a CFC only if its 
U.S. 10% shareholders collectively own more than 50% of the total combined 
voting power or total value of the corporation's stock on any day (the "50% 
Test"). However, for purposes only of taking into account Subpart F Insurance 
Income, a foreign corporation will be treated as a CFC if (i) more than 25% of 
the total combined voting power or total value of its stock is owned by U.S. 10%
shareholders and (ii) the gross amount of premiums or other consideration in 
respect of risks outside its country of incorporation exceeds 75% of the gross 
amount of all premiums or other consideration in respect of all risks (the "25% 
Test"). It is anticipated that the gross premiums of each of the insurance 
subsidiaries of ACE in respect of Subpart F Insurance Income will exceed 75% of 
its gross premiums in respect of all risks so that the 25% Test, rather than the
50% Test, will be applicable with respect to its Subpart F Insurance Income. 
However, the 50% test will continue to apply to ACE itself.

     After the Amalgamation, all the capital stock of ACE Insurance, CODA, and 
the ACE Reinsurance Subsidiary will be owned directly or indirectly by ACE. In 
determining the U.S. 10% shareholders of ACE Insurance, CODA, or the ACE 
Reinsurance Subsidiary, U.S. Persons who are shareholders of ACE are considered 
as owning proportionately the stock of ACE Insurance, CODA, and the ACE 
Reinsurance Subsidiary. After the Amalgamation, U.S. Persons who own, directly, 
indirectly or by attribution under the rules of Section 958(b) of the Code, more
than 10% in value of the stock of ACE will not own more than 25% of the total 
combined voting power or value of the stock of ACE. As a result, none of ACE 
Insurance, CODA, or the ACE Reinsurance Subsidiary, will be a CFC under the 25% 
Test. However, depending on the future ownership of ACE stock, any U.S. Person 
who subsequently acquires 10% or more of the stock of ACE may be required to 
include their share of the Subpart F income of ACE and its subsidiaries in their
U.S. taxable income. It is not expected that ACE itself would ever be a CFC 
under the 50% test, so U.S. persons are not expected to have to include any of 
ACE's Subpart F income in their U.S. taxable income.

     United States--RPII companies. A different definition of "controlled 
foreign corporation" is applicable in the case of a foreign corporation which 
earns related person insurance income ("RPII"). RPII is defined in Code Section 
953(c)(2) as any "insurance income" (as defined above) attributable to policies 
of insurance or reinsurance with respect to which the person (directly or 
indirectly) insured is a "U.S. shareholder" of the foreign corporation or a 
"related person" to such a shareholder. For purposes only of taking into account
RPII, and subject to the exceptions described below, an insurance subsidiary of 
ACE will be treated as a CFC it its


                                                                              7/

<PAGE>
 
"RPII shareholders" (as defined below) collectively own, directly, indirectly, 
or by attribution under Code Section 958(b), 25% or more of the total combined 
voting power or value of such subsidiary's stock on any day during a fiscal 
year. If an insurance subsidiary of ACE is a CFC under the special RPII rules 
for an uninterrupted period of at least 30 days during any fiscal year, a U.S. 
Person who owns, directly or indirectly through foreign entities, shares of 
shares of such subsidiary on the last day of such fiscal year must include in 
its gross income for U.S. federal income tax purposes its allocable share of 
RPII for the entire taxable year, subject to certain modifications. For purposes
of inclusion of RPII from an insurance subsidiary of ACE in the income of U.S. 
Persons who own ACE Ordinary Shares, unless an exception applies, the term "RPII
shareholder" includes all U.S. Persons who own, directly or indirectly through 
foreign entities, any amount (rather than 10% or more) of the ACE Ordinary 
Shares. Generally, the term "related person" for purposes of the RPII rules 
means someone who controls or is controlled by the RPII shareholder or someone 
who is controlled by the same person or persons which control the RPII 
shareholder. Control is measured by either more than 50% in value or more than 
50% in voting power of stock, with respect to corporations, or more than 50% of 
the beneficial interests, with respect to partnerships, trusts, or estates, 
applying constructive ownership principles similar to the rules of Section 958 
of the Code. The term "related persons" also includes, with respect to insurance
policies covering liability arising from services performed as a director, 
officer or employee of a corporation or a partner or employee of a partnership,
the person performing such services and the entity for which the services are
performed.

     The above RPII rules do not apply if (A) direct and indirect insureds and 
persons related to such insureds, whether or not U.S. persons, are treated as 
owning less than 20% of the voting power and less than 20% of the value of the 
stock of ACE's insurance company subsidiaries, or (B) the RPII of each of ACE's 
insurance subsidiaries, determined on a gross basis, is less than 20% of each 
such subsidiary's gross insurance income for the taxable year. ACE believes that
the RPII income of each of ACE Insurance and CODA has been, and should be for 
the foreseeable future, less than 20% of such subsidiary's gross insurance 
income for the taxable year and, based in part on information provided by 
Tempest, it is expected that the ACE Reinsurance Subsidiary's RPII income will 
constitute less than 20% of its gross insurance income for future taxable years.
As a consequence, the special RPII rules should not apply, and U.S. Persons 
owning ACE Ordinary Shares should not be required to include in gross income any
RPII income under the special RPII rules. The IRS may assert, however, that 
ACE's reinsurance subsidiaries indirectly reinsure shareholders of ACE. ACE does
not expect any of its subsidiaries to enter into reinsurance arrangements where 
the ultimate risk insured is that of a holder of ACE Ordinary Shares that is a 
U.S. person or person related to such a U.S. person at a level which would cause
any subsidiary to have RPII income of 20% or more of its gross insurance income.
However, unless final Treasury Regulations under Code Section 953 provide that 
this rule would apply only if the reinsured entity is fronting for another 
party, it may be difficult for ACE to obtain and, if requested of ACE or a 
shareholder by the IRS, provide shareholders with enough information to document
and be certain that each of ACE's subsidiaries providing significant reinsurance
have satisfied the 20% test. ACE believes that it is unlikely that enough of the
underlying reinsured parties will own sufficient ACE Ordinary Shares to cause 
the RPII income of any of ACE's subsidiaries to be 20% or more of their gross 
insurance income and ACE will endeavor to avoid failing the 20% test. However, 
the ultimate application of the RPII rules and the proof that will be required 
to establish compliance thereunder is uncertain and each prospective investor 
should consult their own tax advisor with respect to this issue.

     United States--Passive foreign investment companies. Code Sections 1291 
through 1297 contain special rules applicable to foreign corporations that are 
"passive foreign investment companies" ("PFIC's"). In general, a foreign 
corporation will be a PFIC if 75% or more of its gross income constitutes 
"passive income" (the "75% Income Test") or 50% or more of its assets produce, 
or are held for the production of, passive income (the "50% Asset Test"). If ACE
were to be characterized as a PFIC, its U.S. shareholders would have to make an 
election (a "QEF Election") to be taxable currently on their pro-rata shares of 
earnings of ACE whether or not such earnings were distributed or they would be 
subject to a special tax and an interest charge at the time of the sale of, or 
receipt of an "excess distribution" with respect to, their shares, and a portion
of any gain may be recharacterized as ordinary income, which for an individual 
would be taxed at the highest marginal rate of 39.6%.


                                                                              8/

In general, a shareholder receives an "excess distribution" if the amount of the
distribution is more than 125% of the average distribution with respect to the
stock during the three preceding taxable years (or shorter period during which
the taxpayer held the stock). In general, the special tax and interest charges
are based on the value of the tax deferral of the taxes that are deemed due
during the period the U.S. shareholder owned the shares, computed by assuming
that the excess distribution or gain (in the case of a sale) with respect to the
shares was taxed in equal portions throughout the holder's period of ownership
at the highest marginal tax rate. The interest charge is computed using the
applicable rate imposed on underpayments of U.S. federal income tax for such
period. In general, if a U.S. Person owns stock in a foreign corporation during
any taxable year in which such corporation is a PFIC and such shareholder does
not make a QEF Election, the stock will be treated as stock in a PFIC for all
subsequent years.

     For the above purposes, "passive income" is defined to include income of a
kind that would be characterized as foreign personal holding company income
under Code Section 954(c), and generally includes interest, dividends, annuities
and other investment income. The PFIC statutory provisions contain and express
exception for income "derived in the active conduct of an insurance business by
a corporation which is predominantly engaged in an insurance business . . ."
"This exception is intended to ensure that income derived by a bona fide
insurance company is not treated as passive income. Thus, to the extent such
income is attributable to financial reserves in excess of the reasonable needs
of the insurance business, it may be treated as passive income for purposes of
the PFIC rules. The PFIC statutory provisions also contain a look-through rule
that states that, for purposes of determining whether a foreign corporation is a
PFIC, such foreign corporation shall be treated as if it "received directly its
proportionate share of the income . . . "and as if it "held its proportionate
share of the assets . . ." of any other corporation in which it owns at least
25% of the value of the stock.

     In ACE's view each of its direct and indirect insurance subsidiaries
(including the ACE Reinsurance Subsidiary, after the Effective Time) is
predominantly engaged in an insurance business and does not have financial
reserves in excess of the reasonable needs of its insurance business. Under the
look-through rule, ACE would be deemed to own its proportionate share of the
assets and to have received its proportionate share of the income of ACE
Insurance, CODA, and the ACE Reinsurance Subsidiary for purposes of the 75%
Income and 50% Assets Test. However, no regulations interpreting the substantive
PFIC provisions have yet been issued. Therefore, substantial uncertainty exists
with respect to their application or their possible retroactivity. Each U.S.
Person who holds ACE Ordinary Shares should consult his tax advisor as to the
possible effects of these rules.

     Information Reporting. Every U.S. Person who "controls" a foreign
corporation by owning directly or by attribution more than 50% of the total
value of shares of all classes of stock of such corporation, for an
uninterrupted period of 30 days or more during a fiscal year of that
corporation, must file IRS Form 5471 with its U.S. income tax return. However,
the IRS has the authority to, and does require, any U.S. Person treated as a
U.S. 10% shareholder or RPII shareholder of a CFC that owns shares directly or
indirectly through a foreign entity to file a Form 5471. In addition, U.S.
Persons who own more than 5% in value of the outstanding stock of ACE or its
subsidiaries at any time during a taxable year are required in certain
circumstances to file Form 5471 even if neither corporation is a CFC. A tax- 
exempt organization that is treated as a U.S. 10% shareholder or a RPII
shareholder for any purpose under subpart F will be required to file a Form 5471
in the circumstances described above. Failure to file Form 5471 may result in
penalties.

     Dispositions of ACE Ordinary Shares. Subject to the discussion elsewhere
relating to the potential application of the CFC and PFIC rules, gain or loss
realized by a U.S. ACE Shareholder on the sale, exchange or other disposition of
ACE Ordinary Shares will be includible in gross income as capital gain or loss
in an amount equal to the difference between such holder's basis in the ACE
Ordinary Shares and the amount realized on the sale, exchange or other
disposition. If a U.S. ACE Shareholder's holding period for the ACE Ordinary
Shares is more than one year, any gain will be subject to the U.S. federal
income tax at a current maximum marginal rate of 28% for individuals and 35% for
corporations.

earnings and profits during the period that the shareholder held the shares
(with certain adjustments). Code Section 953(c)(7) generally provides that
Section 1248 also will apply to the sale or exchange of shares by a U.S.
shareholder in a foreign corporation that earns RPII and is characterized as a
CFC under the RPII rules if the foreign corporation would be taxed as an
insurance company if it were a domestic corporation, regardless of whether the
shareholder is a 10% shareholder or whether RPII constitutes 20% or more of the
corporation's gross insurance income.

     ACE believes, based on the advice of counsel, that Code Section 1248 will
not apply to dispositions of ACE Ordinary Shares, so long as ACE is not a CFC,
because ACE is not directly engaged in the insurance business. There can be no
assurance, however, that the IRS will interpret proposed regulations under Code
Section 953 in this manner or that the Treasury Department will not amend the
proposed regulations under Section 953 or other regulations to provide that
Section 1248 will apply to dispositions of shares in a corporation such as ACE
which is engaged in the insurance business directly on indirectly through its
subsidiaries. If the IRS or Treasury Department were to take such action ACE
would notify shareholders that Code Section 1248 will apply to dispositions of
Common Shares.

     Foreign Tax Credit.  Because it is anticipated that U.S. Persons will own a
majority of ACE's shares after the Amalgamation and because a substantial part
of the insurance business of ACE's subsidiaries includes the insurance of U.S.
risks only a portion of the RPII and Subpart F inclusions (if any) and dividends
paid by ACE (including any gain from the sale of ACE Ordinary Shares that is
treated as a dividend under Code Section 1248) will be treated as foreign source
income for purposes of computing a shareholder's U.S. foreign tax credit
limitation.  Except in the case of U.S. 10% shareholders it is likely that all
of the RPII and Subpart F inclusions (if any) and dividends that are foreign
source income will constitute either "passive" or "financial services" income
for foreign tax credit limitation purposes. Thus, it may not be possible for
certain U.S. shareholders to utilize excess foreign tax credits to reduce U.S.
tax on such income.

     Other.  Dividends paid by ACE to U.S. corporate shareholders will not be
eligible for the dividends received deduction provided by Code Section 243.

     Except as discussed below with respect to backup withholding, dividends
paid by ACE will not be subject to a U.S. withholding, tax.

     Information reporting to the IRS by paying agents and custodians located in
the U.S. will be required with respect to payments of dividends (if any) on the
ACE Ordinary Shares to U.S. Persons or to paying agents or custodians located in
the U.S. In addition, a holder of ACE Ordinary Shares may be subject to backup
withholding at the rate of 31% with respect to dividends paid by such persons,
unless such holder (a) is a corporation or comes within certain other exempt
categories and, when required, demonstrates this fact; or (b) provides a
taxpayer identification number, certifies as to no loss of exemption from backup
withholding and otherwise complies with applicable requirements of the backup
withholding rules. The backup withholding tax is not an additional tax and may
be credited against a holder's regular Federal income tax liability.

     Sales of ACE Ordinary Shares through brokers by certain U.S. Persons also
may be subject to backup withholding. Sales by corporations, certain tax-exempt
entities, individual retirement plans, REITs, certain financial institutions,
and other "exempt recipients" as defined in applicable Treasury regulations
currently are not subject to backup withholding.  Holders of ACE Ordinary Shares
should consult their own tax advisors regarding the possible applicability of
the backup withholding rules to sales of their ACE Ordinary Shares.

     The foregoing discussion (including and subject to the matters and 
qualifications set forth in such summary) is based on current law and is for 
general information only.  The tax treatment of a holder of ACE Ordinary Shares 
for U.S. federal income, state, local or non-U.S. tax purposes may vary 
depending on the holder's particular tax situation.  Legislative, judicial or 
administrative changes or interpretations may be forthcoming that could be 
retroactive and could affect the tax consequences to holders of ACE Ordinary 
Shares.  PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS 
CONCERNING THE FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES TO THEM OF 
OWNING THE ACE ORDINARY SHARES.
