Item 1. Business
 
 Introduction
 
  XL Capital Ltd ("XL" or the "Company") is a holding company organized under
the laws of the Cayman Islands. XL was incorporated on March 16, 1998 as the
successor to EXEL Limited, a Cayman Islands corporation organized in 1986
("EXEL"), in connection with EXEL's merger with Mid Ocean Limited, a Cayman
Islands corporation ("Mid Ocean"). In the merger, which was completed on
August 7, 1998, all of the shares of EXEL and Mid Ocean were exchanged for
shares in the Company pursuant to two schemes of arrangement (the
"Arrangements") approved by the Grand Court of the Cayman Islands in
accordance with Section 85 of the Companies Law (1995 Revision) of the Cayman
Islands. The Company operated under the name "EXEL Limited" from completion of
the merger until February 1, 1999, when its current name was approved by the
requisite vote of the Company's shareholders. References herein to "XL" or the
"Company" also shall include EXEL unless the context otherwise requires.
Through its subsidiaries, the Company is a leading provider of insurance and
reinsurance, including coverages relating to certain financial risks, to
industrial, commercial and professional service firms, insurance companies and
other enterprises on a worldwide basis.
 
  XL Insurance Ltd, an insurance company organized under the laws of Bermuda
("XLI"), and its subsidiaries are the Company's principal insurance
subsidiaries. XLI was formed in 1986 in response to a shortage of high excess
liability coverage for Fortune 500 companies in the United States. In 1990,
XLI formed XL Europe Insurance, an insurance company organized under the laws
of the Republic of Ireland ("XLE"), to serve European clients. In 1998, XLI
acquired Folksamerica General Insurance Company (renamed X.L. Insurance
Company of America, Inc. ("XLIA")), an insurance company domiciled in the
State of New York and possessing property and casualty insurance licenses in
approximately 20 states and reinsurance licenses in approximately 14 states,
and formed X.L. Risk Solutions, Inc., an insurance company domiciled in the
State of Connecticut ("XLRS"). XLI also has a representative office in
Australia.
 
  The Company's reinsurance operations are conducted primarily through XL Mid
Ocean Reinsurance Ltd, an insurance company organized under the laws of
Bermuda ("XLMORe"), and its subsidiaries. On August 7, 1998, XLMORe was formed
through the merger of X.L. Global Reinsurance Company, Ltd. ("XLGRe") and Mid
Ocean Reinsurance Company Ltd. ("MORe"). XLGRe was formed in November 1997
through the merger of X.L. Reinsurance Company, Ltd. ("XLRe") and Global
Capital Reinsurance Company Limited ("GCRe") following EXEL's acquisition of
GCR Holdings Limited, a Cayman Islands holding company ("GCR"), on June 12,
1997. XLRe commenced operations on December 1, 1995 to write specialty
reinsurance business. MORe and GCRe were organized in 1992 and 1993,
respectively, initially to write property catastrophe reinsurance following
severe hurricanes which struck the southeastern United States in the late
1980's and early 1990's. Each of XLRe, MORe and GCRe was organized as an
insurance company under the laws of Bermuda. XLMORe maintains branches in
London and Singapore and a European contact office in Munich.
 
  The Company's operations at Lloyd's are conducted through The Brockbank
Group plc, a company organized under the laws of England, and its subsidiaries
(together, "Brockbank"). Brockbank is a leading Lloyd's managing agency which
manages five Lloyd's syndicates, two of which are dedicated corporate
syndicates ("corporate syndicates") whose capital is provided solely by the
Company and its subsidiaries. Mid Ocean acquired 51% of Brockbank in December
1995 and the remaining 49% in August 1997. The two corporate syndicates, which
commenced operations with effect from January 1, 1996, underwrite property,
marine and energy, aviation, satellite, professional indemnity, U.K. motor and
other specialty lines of insurance and reinsurance to a global client base. In
1998, the aggregate premium limit of the two corporate syndicates was
approximately $340 million, and the total capacity under management by
Brockbank was approximately $900 million. As a managing agency, Brockbank
receives fees and commissions in respect of the underwriting services it
provides to syndicates.

  In October 1998, the Company sold its 21% interest in Venton Holdings
Limited, a Bermuda holding company for the Venton managing agency group at
Lloyd's (together, the "Venton Group"). Prior to the sale, subsidiaries of the
Company provided reinsurance coverage to the Venton Group, which writes
principally professional indemnity, directors and officers liability and
fiduciary liability insurance coverages.
 
  The Company participates in several joint ventures of strategic importance.
In general, the Company has pursued a strategy of entering into joint ventures
with organizations which possess expertise in lines of business that the
Company wishes to enter. The Company's principal joint ventures are in the
areas of financial guaranty insurance, life insurance for high net worth
individuals, Latin American reinsurance, political risk insurance and currency
overlay and related risk management.
 
  In November 1998, the Company entered into a joint venture (the "FSA Joint
Venture") with Financial Security Assurance Holdings Ltd., a New York
corporation ("FSA"), to write certain types of financial guaranty insurance
and reinsurance. FSA, through its subsidiaries, is primarily engaged in the
business of providing financial guaranty insurance on asset-backed and
municipal obligations. Under the terms of the joint venture, each of the
Company and FSA formed a Bermuda insurance company in which it is the majority
shareholder and made a minority investment in the company formed by its co-
venturer. The Company formed and maintains majority ownership of XL Financial
Assurance Ltd ("XLFA"). FSA formed and maintains majority ownership of
Financial Security Assurance International Ltd. ("FSAI"). Each of XLFA and
FSAI has a capitalization of approximately $100 million. As part of the joint
venture, the Company and FSA exchanged approximately $80 million of each
other's stock, following which the Company owned approximately 6% of the
issued and outstanding common stock of FSA.
 
  In June 1998, the Company formed Reeve Court Insurance Ltd., an insurance
company organized under the laws of Bermuda ("Reeve Court"), as a joint
venture with such company's management for the purpose of providing life
insurance to high net worth individuals. Reeve Court has a total
capitalization of approximately $100 million.
 
  In October 1997, the Company and Risk Capital Holdings, Inc., a Delaware
corporation ("RCHI"), which holds all of the outstanding shares of Risk
Capital Reinsurance Company, a Nebraska corporation ("RCRe"), organized LARC
Holdings, Ltd., a Bermuda corporation ("LARC"), which holds all of the shares
of Latin American Reinsurance Company, Ltd., a Bermuda insurance company
("LARe"). LARe has approximately $100 million in shareholders' equity and
provides multi-line reinsurance to the Latin American reinsurance market,
concentrating on short-tail, multi-peril property reinsurance and, to a lesser
extent, casualty, marine, aviation and other lines of reinsurance on both a
treaty and facultative basis. XLMORe owns approximately 75% of the outstanding
shares of LARC. The Company indirectly owns approximately 28% of RCHI.
 
  In March 1997, XLI became a founding shareholder along with RCHI and another
insurance company of Sovereign Risk Insurance Ltd. ("Sovereign"), a Bermuda-
based managing general agency formed to underwrite selected political risk
insurance coverages. The Company owns 40.5% of Sovereign.
 
  In 1996, the Company acquired approximately 28% of Pareto Partners
("Pareto"), a firm which specializes in foreign currency overlay management
and related services. At December 31, 1998, Pareto had approximately $26
billion of assets under management. The Company works closely with Pareto to
develop new products and ventures, including the F/XLSM foreign currency
protection product offered by XLI.
 
  On December 2, 1998, the Company signed a definitive agreement to acquire
all of the outstanding shares of Intercargo Corporation, a Delaware
corporation ("Intercargo"), for $12.00 per share, or approximately $88
million. Intercargo, through its subsidiaries, underwrites specialty insurance
products for companies engaged in international trade, including U.S. customs
bonds and marine cargo insurance. At September 30, 1998, Intercargo had total
assets of $165 million and shareholders' equity of $81 million. The
transaction is subject to approval by Intercargo's shareholders, regulatory
approvals and customary closing conditions.
 
  Each of XLI, XLE and XLMORe possesses claims paying ratings of AA from
Standard & Poor's Corporation ("S&P") and A+ from A.M. Best Company, Inc.

Business Strategy
 
  The Company's strategy is to be the premier provider of strategic financial
risk solutions to specific global markets by applying intellectual and
financial resources to assure its customers' economic vitality and enhance
their competitive positions. Management believes that pursuing this strategy
will improve the Company's ability to differentiate itself from its
competitors, diversify its mix of business and revenue stream, reduce its
dependence on business lines which may be highly price sensitive and build
shareholder value.
 
  The Company's strategy calls for its subsidiaries to go beyond offering
traditional insurance and reinsurance products to designing risk transfer
programs that address specific customer needs with respect to a broad range of
risks. These include certain types of financial risks and other non-
traditional insurance risks which the Company believes can be properly
analyzed and underwritten. As part of this approach, the Company's strategy
contemplates providing income statement and balance sheet protection to its
customers, involving in some instances structured portfolio transfers of
strategic importance to its customers. The Company also believes there will be
opportunities to build investment features into its risk transfer products.
The Company intends to retain its traditional focus generally on high
severity, low frequency risks.
 
  In order to pursue its strategy effectively, the Company may need to secure
access to skills and capabilities in areas which historically have not been
found in the insurance and reinsurance industry. Accordingly, successful
implementation of the Company's strategy is expected to involve not only
maximizing its financial strength but attracting and retaining highly skilled
and motivated employees. It may also require entering into coordinated
initiatives, joint ventures or alliances with one or more strategic partners,
making strategic investments and, where appropriate, acquiring other
businesses of strategic value to the Company and its subsidiaries.
 
Business Operations
 
  The Company reported net premiums written of $649.9 million, $439.4 million
and $467.7 million for the years ended November 30, 1998, 1997 and 1996,
respectively.

Insurance
 
  The Company, through its subsidiaries, provides third-party general
liability insurance, other liability insurance (including directors and
officers liability insurance, professional liability insurance, employment
practices liability insurance and integrated liability insurance), property
insurance and other insurance covers (including political risk insurance and
financial products). The liability insurance is written on an excess basis and
the loss experience is characterized as low frequency and high severity.
Property insurance is written on a pro rata as well as an excess basis.
Property policies written on a pro rata basis can have losses attaching at
lower levels, resulting in loss experiences that can be higher frequency and
lower severity than those associated with the Company's other insurance lines.

  As the Company's U.S. insurance subsidiaries were not yet fully operational
in 1998, the descriptions which follow relate to coverages offered by XLI and
XLE. The descriptions which follow are summary in nature. The terms and
conditions of individual policies govern, and nothing set forth herein
constitutes an admission of coverage or other liability or an interpretation
as to how any particular policy provision should be interpreted.
 
 General Liability
 
  General liability policies offered by the Company's insurance subsidiaries
cover occurrences causing unexpected and unintended personal injury or
property damage (as well as advertising liability) to third parties arising
from events or conditions which commence at or subsequent to an inception date
(or retroactive date, if applicable, but not prior to January 1, 1986) and
prior to the expiration of the policy, provided proper notice is given during
the term of the policy or the discovery period. With respect to the use of
products, the coverage applies where unexpected and unintended personal injury
or property damage to a third party caused, allegedly caused or deemed to have
been caused by the use of a product takes place during the term of the policy.
Where certain injury, damage or liability to third parties is expected or
intended by the insured, the policy provides coverage for injury, damage or
liability when the actual injury, damage or liability incurred is
fundamentally different in nature or vastly greater in order of magnitude than
expected. All claims for integrated occurrences are added together and treated
as one occurrence (thereby limiting such losses to one policy limit) with
respect to the policy in effect when the occurrence or claim is first reported
regardless of the length of the period over which such losses or liabilities
occur, although special notice requirements are imposed with respect to such
losses. The general liability policies generally do not "drop down" to provide
coverage below the per-occurrence attachment point even in the event of
exhausted underlying insurance policy aggregates.
 
  Coverage includes product liability, claims resulting from abrupt pollution,
punitive damages (for unexpected or unintended damage/injury) and payment of
legal fees, as well as a broad range of catastrophic exposures such as
explosions, fires, utility blackouts and other catastrophic events not
excluded from coverage. Coverage generally excludes gradual pollution (other
than gradual pollution resulting from a products liability claim), property
damage arising out of most professional services, commercial airline risks,
certain marine exposures, and liability for injury or damage caused by, among
other things, asbestos, tobacco, intra-uterine devices, silicone implants and
nuclear risks. Unlike traditional insurance policy forms, disputes under the
policies are required to be settled by arbitration in London. Under the policy
arbitration clause, each party selects one arbitrator and the two arbitrators
so selected choose a third arbitrator. The English Arbitration Act of 1950, as
amended and supplemented, governs the arbitration under XLI policies (with
International Chamber of Commerce rules governing XLE policies).
 
  Rather than issuing separate annual policies, a perpetual policy is issued
(which is subject to an annual underwriting review) with an annual aggregate
limit (subject to reinstatement). The policy remains in effect until canceled
or not continued. The terms, conditions, exclusions, deductibles and limit
applicable to an occurrence are determined by the policy in effect at the time
notice thereof is first given. Coverage is provided on an occurrence-reported
policy form up to a maximum of $200 million per occurrence and annual
aggregate in excess of a minimum attachment point of $15 million per
occurrence. Because the inception date (or, if applicable, the retroactive
date) remains unchanged, the exposure under each policy usually increases each
additional year that the policy is in force. The exposure to unreported claims
thus rolls forward each year, which is provided for by the establishment of
significant incurred but not reported ("IBNR") reserves. Each year's coverage,
however, is subject to an aggregate limit, and the limits of any given year
are not available for occurrences first reported in a subsequent year
notwithstanding that the injury or damage took place in that year. Premiums
are adjusted annually. A single event or set of circumstances may constitute
an insured occurrence under policies of different policyholders, resulting in
multiple claims exposure with respect thereto. Such events or circumstances
could have a material adverse effect on the results of the Company.
 
  The policy permits cancellation by the insurer with refund of the unearned
premium at any time, except in the case of discovery period coverage, upon 90
days' prior written notice to the policyholder. The policy permits
 
                                       4
<PAGE>
 
cancellation by a policyholder at any time with a pro-rata refund of premium.
If the basic coverage of the policy is canceled or discontinued, the insured
is given the option of purchasing discovery coverage (in respect of
occurrences taking place subsequent to the inception/retroactive date and
prior to cancellation or discontinuance of basic coverage) on an ongoing basis
for as long as is desired by the policyholder (with no maximum duration) for
predetermined annual premiums.
 
  As contrasted with the standard policy form which provides for annual
determination of premiums and limits, the Company offers to certain of its
policyholders endorsements providing cover generally for two additional annual
periods (aggregating a total of three years), with either an annual aggregate
or term limit and with the provision for reinstatement of the limit selected.
Premiums are generally prepaid in whole or in part for the period of the
contract. Such endorsements limit the circumstances under which either the
policyholder or the insurer may cancel and provide that the otherwise
predetermined premium for the three-year period may be adjusted in certain
specified circumstances. It is contemplated that policyholders may be given
the opportunity to roll the three-year term forward year-by-year based on
premiums and other terms and conditions to be negotiated each year.
 
 Other Liability
 
  Other liability includes directors and officers liability insurance,
professional liability insurance, employment practices liability insurance and
integrated liability insurance branded as XL Risk Solutions.
 
  Directors and Officers Liability. Directors and Officers liability coverage
is written on a claims-made basis providing up to a maximum of $25 million in
excess of $20 million for United States risks and up to $50 million for
individual director indemnification and excluding corporate reimbursement in
excess of $20 million, or $15 million in excess of $15 million for non-United
States risks, or a limit of $25 million in excess of not less than $25
million. The policy generally adopts the terms, conditions and exclusions in
the primary or other underlying policy. Each insured is rated separately. In
contrast to the general liability policy, the directors and officers policy is
for a designated period. Also, unlike the general liability policy, the
directors and officers policy "drops down" upon erosion or exhaustion of
underlying aggregates by multiple claims. The policy can be canceled by the
insurer upon typically 90 days' notice (with the insurer retaining a pro rata
proportion of the premium) or by the policyholder at any time with the insurer
retaining a short rate proportion (i.e., more than pro rata) of the premium.
If the insurer cancels or refuses to renew the policy, the policyholder is
given the option of purchasing discovery coverage for a specified period of
time (generally one to three years) at a predetermined premium. As with the
general liability form, disputes are required to be settled by arbitration in
London. Under the policy arbitration clause, each party selects one arbitrator
and the two arbitrators so selected choose a third arbitrator.
 
  Professional Liability. Professional liability risks are written either on a
follow-form basis (i.e., the policy generally adopts the terms, conditions and
exclusions of the underlying policy, which usually is a "claims-made" policy)
or on a form which is structured similarly to the general liability form in
that it is extended from year to year (with annual underwriting reviews).
Coverage is provided for certain categories of risk up to a maximum of $50
million with a minimum attachment of $25 million, or $20 million for law
firms. The policy covers "wrongful acts" (instead of occurrences), subject to
customary exclusions, and covers punitive damages arising therefrom. As with
the other policy forms, disputes are required to be settled by arbitration in
London. In contrast to the general liability policy, the discovery period is
of finite duration (generally one to three years). Where the policy is written
on a claims made "stand alone" basis (i.e., it does not follow the warranties,
terms, conditions or exclusions of underlying policies), it does "drop down"
upon erosion or exhaustion of the aggregate limits of underlying policies by
multiple wrongful acts in the case of law firms and certain other insureds
(i.e., in these instances the attachment point applies on an aggregate rather
than a per wrongful act basis). The underlying policies of an insured seeking
professional liability coverage are reviewed and evaluated as part of the
underwriting process.
 
  Employment Practices Liability. In 1997, XLI introduced coverage for
employment practices liability. Coverage is provided up to $100 million with a
minimum attachment of $1 million. Employment practices
 
                                       5
<PAGE>
 
liability risks are written on a claims made and reported policy. The policy
is written on an annual basis and covers claims brought by an employee against
an insured for certain covered employment practices such as job
discrimination, sexual harassment and other employment related misconduct. As
with other XLI products, the employment practices liability policy has XLI's
standard arbitration clause which requires disputes to be settled by
arbitration in London.
 
  XL Risk Solutions. XL Risk Solutions is a coordinated initiative with CIGNA
Risk Solutions offering multi-year, combined line coverages for traditional
casualty coverages, including general, directors and officers and professional
liability, and property coverage plus blended finite coverage for risks which
traditionally have had difficulty placing cover. The target market is large
and medium size companies that are trying to simplify and streamline the risk
transfer process. CIGNA Corporation ("CIGNA") provides services and fronting
policies to meet U.S. regulatory requirements and provides an excess policy
for the balance of capacity and coverages required. Available capacity by line
of coverage is $60 million to $200 million depending upon the lines selected.
Attachment levels may in certain situations be provided below traditional
stated levels subject to the underwriting requirements. Programs are typically
custom designed to meet specific needs with each customer.
 
 Property
 
  Property policies are primarily underwritten on an excess of loss occurrence
and pro rata form (except earthquake and flood when provided) utilizing
engineering reports, statement of values, prior loss history, annual report
and other publicly available information. Earthquake and flood coverage are
written on an excess of loss attachment basis which may be eroded in a given
policy year by accumulated losses from separate occurrences as customary in
the industry. When written as such, earthquake and flood have annual aggregate
limits. All classes of business are considered. The minimum attachment points
are generally $25 million for industrial/commercial accounts and $100 million
for oil/petrochemical accounts. Industrial/commercial accounts will also be
written on a pro rata basis with attachments as low as $1 million.
 
  Coverage can be provided worldwide on an all-risk or named peril basis of
direct physical loss or damage with options for time element (e.g., business
interruption, extra expense, rental value, etc.), earthquake, flood, and
boiler and machinery coverage. Policies can be written on a modified follow
form or XLI form. Typical exclusions include but are not limited to war risk,
nuclear, pollution, and others customary in property policy coverage. Unlike
traditional property policies, disputes under XLI policies are required to be
settled by arbitration in London with each party selecting one arbitrator and
the two arbitrators so selected choosing a third arbitrator.
 
  The maximum net capacity for any of the insurance subsidiaries for any one
insured is $100 million per occurrence with $10 million annual aggregate for
high frequency/severity earthquake (California, Japan, etc.) when provided.
Earthquake and coastal wind exposures are identified and monitored (policy
limit accumulations) by subzones worldwide in order to limit exposure to an
excessive concentration of catastrophic loss.
 
 Other
 
  Insurance is also provided to cover political risk. Political risk
insurance, including coverages for expropriation, currency inconvertibility
and certain other types of political risk associated with cross-border
investment, is provided through the Company's interest in Sovereign. Policies
written by Sovereign are subscribed 50% by each of XLI and Sovereign's other
insurance company shareholder, with RCRe participating in up to 10% of each
risk written on a quota share basis. Sovereign's per-country aggregate limit
is $100 million, except with respect to Argentina, Brazil, China and Indonesia
which have an aggregate limit of $250 million each, and its per risk limit is
$50 million.
 
                                       6
<PAGE>
 
  XLI also offers insurance and reinsurance solutions for certain types of
financial risks. In 1998, XLI introduced a foreign currency protection product
and began writing financial guaranty insurance and reinsurance in respect of
selected credit risks.
 
  XLI sells customized basket and, in certain circumstances, single-currency
options for the purpose of mitigating exposures which corporate and financial
institution customers have to selected major currencies. XLI engages Pareto as
an advisor to assist in the evaluation of particular foreign currency
protection contracts and to manage the risk associated with such transactions.
Options have a duration of up to one year. Unrealized gains and losses are
marked to market on a periodic basis and reflected quarterly in the Company's
consolidated statements of income. At fiscal year-end 1998, XLI had written
options having an aggregate nominal value of $200 million, with no single
option accounting for more than $100 million. Using its proprietary foreign
currency overlay management technology, Pareto attempts to manage XLI's risk
of loss so that it generally will not exceed 3% of the nominal amount of each
option under the vast majority of possible scenarios. Gains from Pareto's
management activities are also possible. Although XLI believes that Pareto
generally will manage at or above the 3% loss floor and may produce gains on
some contracts, actual losses and gains may be greater or less, respectively,
than anticipated due to a variety of factors, including, without limitation,
flaws in Pareto's highly quantitative, model-driven technology, the inability
to execute hedging and other transactions called for by Pareto's technology in
a timely or cost efficient manner, especially in periods of significant
financial market volatility or illiquidity, and uncertainties surrounding the
application of Pareto's technology, which is predicated on a basket option
approach, to single-currency or other non-basket option types of transactions.
See "Management's Discussion and Analysis of Results of Operations and
Financial Condition--Cautionary Note Regarding Forward-Looking Statements" for
a list of factors which could cause actual results to differ materially from
those contained in any forward-looking statement.
 
  XLI and XLFA provide financial guaranty insurance and reinsurance in respect
asset-backed, future flow and municipal obligations. Financial guaranty
policies generally cover non-payment of principal and interest when due.
Particular types of transactions which XLI and XLFA have underwritten or
considered underwriting include financial guaranty insurance or reinsurance in
respect of bonds issued by public utilities, collateralized bond and
collateralized loan obligations, mortgage-backed securities, certain low
income housing tax credits, prime and sub-prime automobile loans, credit
default swaps, project finance-related obligations and other types of
structured insurance or reinsurance risks, including residual value insurance
for certain asset classes. The underlying risks guaranteed include both OECD
(Organization of Economic Cooperation and Development) and emerging market
issuers and assets. Guarantees provided by XLI an XLFA relate generally, but
not exclusively, to investment grade obligations. Gross and net retentions in
respect of financial guaranty and related risks are determined by XLI and XLFA
on a case-by-case basis in light of the particular credit, actuarial,
structuring and other risks associated with each transaction. Exposure to a
financial guaranty or related risk can exceed $100 million. XLI and XLFA also
may provide financial guaranty "fronting" services in return for fees and
other revenues on behalf of insurers or reinsurers whose claims paying ratings
are below their own. The fronting party is generally required to pay the full
amount of any claim even if it cannot recover all or part of the balance due
from an insurer or reinsurer for which the service was provided.
 
Reinsurance
 
  The Company, through its subsidiaries, writes property catastrophe, property
excess of loss, property pro rata, marine and energy, aviation and satellite
and various other reinsurance to insurers on a worldwide basis. XLMORe
maintains branch offices in London and Singapore as well as a European contact
office in Munich, Germany. The London branch underwrites marine, energy and
aviation risks on a worldwide basis. The Singapore branch underwrites general
reinsurance, treaty and facultative business.
 
  A significant portion of XLMORe's business underwritten consists of large
aggregate exposures to man-made and natural disasters and generally loss
experience is characterized as low frequency and high severity. This may
result in volatility in the Company's financial results. The Company endeavors
to manage its exposures
 
                                       7
<PAGE>
 
to catastrophic events by limiting the amount of its exposure in each
geographic zone worldwide and requiring that its property catastrophe
contracts provide for aggregate limits and varying attachment points.

 Property Catastrophe
 
  XLMORe's property catastrophe reinsurance account is generally "all risk" in
nature. It is therefore exposed to losses from sources as diverse as
windstorms, earthquakes, snow and ice storms, riots, floods, industrial
explosions, fires or any number of other potential disasters. In accordance
with market practice, XLMORe's policies generally exclude certain risks such
as war, nuclear contamination or radiation. XLMORe's predominant exposure
under such coverage is to property damage. However, other risks, including
business interruption, death and injury under workers compensation policies
and other non-property losses also may be covered under a property reinsurance
contract when arising from a covered peril. Property catastrophe reinsurance
provides coverage on an excess of loss basis when aggregate losses and loss
adjustment expenses from a single occurrence of a covered peril exceed the
attachment point specified in the policy. Some of XLMORe's property
catastrophe contracts limit coverage to one occurrence in any one policy year,
but most contracts generally provide for one reinstatement.
 
  In 1998, XLMORe's exposure to the following geographic regions based on net
premiums written were as follows: (i) United States 53.5%; (ii) United Kingdom
5.6%; (iii) Japan 2.6%; (iv) worldwide 28.4%; (v) continental Europe 1.7%;
(vi) Australasia 6.6%; (vii) Caribbean 0.6% and (viii) other 1.0%. XLMORe's
exposures in the United States are concentrated primarily in Florida, Texas,
and the southeastern United States with respect to property damage caused by
hurricanes and other wind-related storms and California for property damage
caused by earthquakes.
 
 Other Property
 
  Other property reinsurance written by XLMORe includes property risk excess
of loss and property pro rata business. Risk excess of loss reinsurance
responds to a loss of the reinsured on a single "risk" of the type reinsured
rather than to aggregate losses for all covered risks as does catastrophe
reinsurance. The risk excess of loss policy protects the reinsured from losses
in excess of its retention level on a single risk. A "risk" in this context
might mean the insurance coverage on one building or a group of buildings or
the insurance coverage under a single policy, which the reinsured treats as a
single risk. Risk excess contracts are generally "all risk" in nature, as
previously described.
 
  XLMORe's property pro rata account includes proportional reinsurance of
direct written property insurance. XLMORe considers this business to be
related to its catastrophe and other property exposures. In proportional
reinsurance, XLMORe assumes a specified proportion of the risk on the
specified coverage and receives an equal proportion of the premium. The ceding
insurer receives a commission, based upon the premiums ceded to the reinsurer,
and the ceding insurer may also be entitled to receive a profit commission
based on the ratio of losses, loss adjustment expense and the reinsurer's
expenses to premiums ceded. A proportional reinsurer is dependent upon the
ceding insurer's underwriting, pricing and claims administration to yield an
underwriting profit. In some instances, XLMORe may be entitled to the benefit
of other reinsurance, known as common account reinsurance, purchased by the
ceding company on an account reinsured by XLMORe on a proportional basis.

<PAGE>
 
 Marine and energy
 
  XLMORe's marine and energy account is written on both a proportional and
excess of loss basis. The proportional business is based on specific areas of
account that are clearly defined with the exception of the reinsurance of
Brockbank Syndicate 861 which is written on a "whole account" basis.
 
 Aviation and satellite
 
  XLMORe's aviation portfolio comprises both direct insurance and reinsurance,
on both a proportional and excess of loss basis. The exposures are derived
through proportional relationships on defined segments of account following
market leaders in the field, with the exception of the reinsurance of
Brockbank Syndicate 861 which is written on a "whole account" basis. Due to
the highly technical nature of the satellite business, the exposures retained
by XLMORe under this portfolio are acquired mostly through proportional
reinsurances of specialist underwriters.
 
 Other
 
  Other reinsurance written by XLMORe includes political risk, nuclear,
accident, fidelity and professional indemnity.

  Brockbank is a leading Lloyd's managing agency which manages five Lloyd's
syndicates, two of which are dedicated corporate syndicates whose capital is
provided solely by the Company. Corporate syndicate number 1209 writes
property, marine and energy, aviation and satellite, professional indemnity,
political risk and other specific lines, primarily of insurance but also
reinsurance, to a globally diverse group of clients. Corporate syndicate
number 2253 writes direct and broker-based motor insurance in the United
Kingdom. These corporate syndicates underwrite parallel to the other
syndicates managed by Brockbank (syndicate number 253 which writes direct
motor insurance and syndicate numbers 588 and 861 which write a composite book
of business).
 
Reinsurance Ceded
 
 From Insurance Operations
 
  Effective December 1, 1995, XLI and XLE entered into a quota share
reinsurance policy with five U.S. reinsurers and one non-U.S. reinsurer
covering general liability risks only. Effective fiscal 1998, three additional
U.S. reinsurers were added to this program, of which one is RCRe. Under the
terms of the policy, XLI will cede 20% of risks with total limits up to $100
million and 25% of risks with total limits in excess of $100 million up to
$150 million. Effective December 1, 1998, 20% of all general liability
business is ceded up to a limit of $150 million. The maximum amount
recoverable from the reinsurers will be the ceded percentage of the original
policy limit on a per occurrence basis, with an annual aggregate of 225% of
the total premium ceded. No single reinsurer participates in excess of 20% of
the quota share. All the reinsurers are rated, of which the lowest as rated by
S&P is BBB. The most significant reinsurers on this program are Fireman's
Fund, Hannover Re and Hartford Re. These companies are rated A, AA+ and AA+ by
S&P with participations of 16.0%, 18.7% and 16.0%, respectively on a
reinsurance balance receivable of $176.9 million.
 
  Effective September 1, 1997, XLI and XLE entered into an excess of loss
casualty catastrophe contract covering all general liability risks. Under the
terms of this policy, XLI and XLE are reinsured for $80 million ultimate net
loss each occurrence excess of a per occurrence retention, subject to an
annual aggregate retention. The maximum amount recoverable from the reinsurers
will be an annual aggregate of $250 million. This policy
 
                                       9
<PAGE>
 
was extended to November 30, 1998 and renewed December 1, 1998. For the year
ended November 30, 1998, 97.75% of this reinsurance was placed with seventeen
reinsurers, all of which are rated. With the exception of two reinsurers, the
lowest as rated by S&P is A-. The other two reinsurers are rated BBB and BB by
S&P, representing a participation of less than 4% on this program.
 
  Property quota share reinsurance of 25% (subject to catastrophe occurrence
limit restrictions) of XLI's property policy limit is purchased from two
Bermuda-based property reinsurers, four U.S. reinsurers and one non-U.S.
reinsurer. All property reinsurers are rated with a minimum S&P rating of A-.
 
  XLI reinsures one third of the first $75 million in limits of employment
practices liability to a U.S. insurer and the remaining excess layer of $25
million to a Bermuda-based insurer.
 
  A quota share arrangement exists between XLI and subsidiaries of CIGNA based
on pre-agreed percentages by line of coverage for blended covers written
through XL Risk Solutions and CIGNA Risk Solutions. These percentages vary
from 12.5% to 90%, but do not exceed XLI's normal capacity on individual lines
of cover. XLI may underwrite an account 100% without CIGNA participation.
 
 From Reinsurance Operations
 
  For the years ended October 31, 1997 and 1996, XLMORe participated in
limited retrocessions. Initially, the majority of such retrocessions
originated from common account reinsurance on assumed business.
 
  In August 1998, XLMORe successfully placed $200 million of retrocessional
property catastrophe cover in a combination reinsurance and capital market
swap transaction. The transaction was offered in two tranches and covered the
upper layers, with a remote possibility of attachment, of XLMORe's hurricane
and earthquake exposure in the United States and its territories and
possessions in the Caribbean. The risk securitization structure is unique in
that it provides retrocessional cover in financial swap form, with claim
recovery triggered by catastrophe losses actually incurred by XLMORe rather
than by a catastrophe index or industry size event.
 
 From Lloyd's Operations
 
  Brockbank, as a part of its business strategy, has historically purchased a
significant amount of reinsurance for its syndicates, including the corporate
syndicates. Corporate syndicate 1209 benefits from the same reinsurance
programs as its parallel syndicates 861 and 588. Reinsurance cover is
purchased to protect the syndicates against extraordinary loss and/or loss
involving one or more of their underwriting classes. The amount purchased is
determined with reference to the syndicates aggregate exposure and potential
loss scenarios.
 
  Corporate syndicate 2253 benefits from the same reinsurance programmes as
its parallel syndicate 253. Reinsurance cover is purchased on a quota share
and excess of loss basis.
 
Competition
 
  The property-casualty insurance and reinsurance industry, including the
Lloyd's market, is highly competitive. The markets for the Company's insurance
and reinsurance products are characterized by strong, and at times intense
price competition driven largely by the substantial amount of excess capacity
currently present in the industry. The Company believes that such competitive
forces will be present in the industry over the short to medium term.
 
  Whereas only a small number of insurers used to compete with the Company's
property-casualty insurance business at the attachments and limits offered by
it, the Company currently estimates there to be at least 12 competitors
worldwide with respect to such business. Similarly, the Company believes there
to be a large number of reinsurers which compete with its reinsurance
business. Many of the Company's competitors possess significantly greater
financial and other resources than the Company. The Company generally competes
on the basis of price, financial strength, coverage terms, claims paying
reputation and customer service.

Underwriting and Marketing
 
 Underwriting
 
  XLI and XLE write liability and property insurance coverage for a wide array
of industry groups, including chemical, industrial, pharmaceutical, property
owners, landlords and tenants, utilities, auto, consumer, rail, oil and
construction with respect to third-party general liability and first-party
property; industrial/manufacturing, utilities, chemical/pharmaceutical and
financial advisors with respect to directors and officers liability; and
lawyers, insurance brokers and insurance companies for professional liability.
Although rates are influenced by a number of factors, including competition,
the Company's insurance rating methodology seeks to set rates individually for
each insured in accordance with claims potential as measured by past experience
and future expectations, the attachment point and amount of underlying
insurance, the nature and scope of insured operations (including the industry
group in which the insured operates), exposures to loss, and other specific
risk factors relevant in the judgement of the underwriters and insurance market
conditions. Underwriters separately evaluate each industry category (and sub-
groups within each category) and premiums are set and adjusted for an insured
based in large part on the industry group in which the insured is placed and
the insured's risk relative to the other risks in the insured's industry group.
Each industry group is reviewed annually to take into account outstanding case
losses and new loss incident reports within each group. Rates may vary
significantly according to the industry group of the insured as well as within
the group.
 
  XLMORe employs an analytical approach to underwriting designed to specify an
adequate premium for a given exposure that is intended to be commensurate with
the amount of capital it anticipates placing at risk. For its property
catastrophe reinsurance business, XLMORe has developed underwriting guidelines
under which it generally limits the amount of exposure it will directly
underwrite for any one reinsured and the amount of the aggregate exposure to
catastrophe losses in any geographic zone. XLMORe believes it has defined zones
such that a single occurrence, such as an earthquake or hurricane, generally
should not affect more than one zone. The definition of XLMORe's zones are
subject to periodic review and change. XLMORe also generally seeks an
attachment point for its property catastrophe reinsurance anticipated to be
high enough to produce a low frequency of loss. XLMORe limits its aggregate
exposure in the retrocessional and pro rata business because it is sometimes
difficult to allocate risks associated with such business to specific
geographic areas.
 
  As part of its underwriting process, XLMORe typically assesses a variety of
factors, including: the reputation of the proposed cedent and the likelihood of
establishing a long-term relationship with the cedent; the geographic area in
which the cedent does business and its market share; a detailed assessment of
catastrophe and risk exposures; historical loss data for the cedent and, where
available, for the industry as a whole in the relevant regions, in order to
compare the cedent's historical catastrophe loss experience to industry
averages; and the perceived financial strength of the cedent.
 
  At Brockbank, the daily acceptance of risk is performed by the active
underwriter, the class underwriters and senior underwriting assistants.
Underwriting authority limits are agreed between the active underwriter, the
class underwriter and the managing agency's board of directors.
 
  As part of the underwriting process, all of the Company's insurance and
reinsurance underwriting operations, including Lloyd's, evaluate potential
exposures to claims, losses and defense costs associated with Year 2000-related
issues. Such claims, losses and costs, to the extent they materialize, could
have a material adverse affect on the Company's results of operations and
financial condition. For more information concerning the impact of Year 2000
issues on underwriting results, see "Management's Discussion and Analysis of
Results of Operation and Financial Condition--Year 2000 Considerations" and "--
Cautionary Note Regarding Forward-Looking Statements."
 
 Marketing
 
  Clients are referred to the Company's subsidiaries through a large number of
insurance brokers who receive from the insured or ceding company a brokerage
commission equal to a percentage of gross premiums. No
 
                                       11

subsidiary of the Company is committed to accept any business from any
particular broker, and brokers do not have the authority to bind any subsidiary
of the Company. All policy applications are subject to approval and acceptance
by the Company's subsidiaries.
 
  Since the Company's inception, J&H Marsh McLennan Global Broking Limited
("J&H Marsh") and its predecessors companies have placed a significant amount
of business with the Company's subsidiaries. In fiscal 1996, 1997 and 1998
approximately 52%, 52% and 45%, respectively, of the Company's consolidated
gross premiums were placed by J&H Marsh or its predecessors and approximately
17%, 19% and 30% respectively, were placed by AON Corporation in fiscal 1996,
1997 and 1998, respectively. Concentration in the insurance and reinsurance
brokerage industry could have a material adverse effect on the Company's
business and results of operations in the future. See "Management's Discussion
and Analysis of Results of Operations and Financial Condition--Cautionary Note
Regarding Forward-Looking Statements." No other broker accounted for more than
10% of gross premiums written in any fiscal year during such period.
 
Unpaid Losses and Loss Expenses
 
  Loss reserves are established due to the significant periods of time that may
elapse between the occurrence of an insured loss, the reporting of the loss to
the Company's operating subsidiaries and the payment of that loss. To recognize
liabilities for unpaid losses, the Company establishes reserves, which are
balance sheet liabilities representing estimates of future amounts needed to
pay claims and related expenses with respect to insured events which have been
reported to the Company. The Company's reserving practices and the
establishment of any particular reserve reflect management's judgement
concerning sound financial practice and do not represent any admission of
liability with respect to any claims made against the Company's subsidiaries.
 
  The method of establishing case reserves for reported claims differs between
the insurance and reinsurance operations. When an insurance claim is reported
to the Company's subsidiaries, its claims personnel determine whether to
establish a "case reserve" for the estimated amount of the ultimate settlement,
if any. The estimate reflects the judgment of claims personnel, based on
general corporate reserving practices and on the experience and knowledge of
such personnel regarding the nature and value of the specific type of claim
and, where appropriate, advice of counsel. Reserves are also established to
provide for the estimated expense of settling claims, including legal and other
fees and the general expenses of administering the claims adjustment process
("loss expense"). Reinsurance case reserves are established based upon reports
received from insureds and reinsureds supplemented by the Company's case
reserve estimates. Periodically, adjustments to the case reserves may be made
as additional information regarding the claims becomes known or partial
payments are made.
 
  Most of the Company's IBNR (incurred but not reported) loss reserves are
derived from its insurance operations. This is because the liability business
that these operations write has a much longer tail than the Company's other
operations. The insurance IBNR is estimated in two steps. First, case reserve
development is estimated with the use of the loss development factor ("LDF")
method. Second, "pure" IBNR is estimated with a frequency and severity
approach. Since coverage is usually triggered when a notice is submitted by an
insured, "pure" IBNR losses exist only when claims with a loss notice develop
into their layers of coverage. The method calculates the ultimate number of
claims (i.e. frequency) via the Bornhuetter-Ferguson technique. The severity
component (average claim size) is developed via a single parameter pareto loss
distribution, adjusted for average attachment points and limits. The Company
believes the methods presently adopted provide a reasonably objective result as
it is based upon the Company's loss data rather than more theoretical models
often used in the low frequency high layer business the Company writes.
 
  Several aspects of the Company's insurance operations complicate the
actuarial reserving techniques for loss reserves as compared to other insurance
companies. Among these aspects are the differences in the policy forms from
more traditional forms, the lack of complete historical loss data for losses of
the same type intended to be covered by the policies and the expectation that
losses in excess of the attachment level of the Company's policies generally
will be characterized by low frequency and high severity, limiting the utility
of claims experience of other insurers for similar claims. Accordingly, the
ultimate insurance claims experience cannot be
 
                                       12
<PAGE>
 
as reliably predicted as may be the case with other insurance companies, and
there can be no assurance that losses and loss expenses will not exceed the
total reserves.
 
  The reinsurance operations and Lloyd's syndicates, unlike the insurance
operations, have industry data available to support estimated reserves. This
data, supported by business knowledge, general market trends and actual
experience, is used to develop reporting patterns and initial expected loss
ratios. Most claims for these operations become known relatively soon. Claims
under property catastrophe and property risk excess treaties will generally
become known and ascertainable within approximately 18 to 24 months from the
date of occurrence giving rise to a claim. Claims under a significant number
of Lloyd's syndicate policies, with the exception of motor, will often become
known and ascertainable with 36 months of the date of the occurrence giving
rise to the claim, but many significant claims will not become known until
after such period. Motor claims involving property damage will generally be
known and paid within 12 months of the occurrence giving rise to the claim,
but claims involving personal injury can take more than 12 months to resolve.
Conversely, claims on the insurance operations generally develop on average 5
to 8 years from the date of occurrence giving rise to the claim.
 
  Losses and loss expenses are charged to income as incurred. The reserve for
unpaid losses and loss expenses represents the accumulation of case reserves,
loss expense reserves and IBNR. During the loss settlement period, additional
facts regarding individual claims and trends usually will become known. As
these become apparent, it often may become necessary to refine and adjust the
reserves upward or downward from time to time. The final liability nonetheless
may be significantly less than or greater than prior estimates.
 
  Conditions and trends that have affected development of liability in the
past may not necessarily occur in the future. Accordingly, it may not be
appropriate to extrapolate future redundancies or deficiencies based on the
tables below.

  Gross case and loss expense reserves as a component of total gross reserves
in 1998 increased to $1.4 billion from $863 million after the payment of $366
million in losses. One of the main reasons for the increase relates to the
acquisition of Mid Ocean and its related reserves. The case reserves for the
reinsurance operations at November 30, 1998 were $318 million compared to $27
million at the beginning of the year. Included in these reserves was $63
million established in respect to hurricane Georges and the SwissAir airline
disaster. One of the contributing factors to the reduction in prior losses was
the related reduction in loss reserves that were acquired with Mid Ocean. The
balance of the change is not attributable to any single or group of related
events, but to normal attrition as losses have developed over time into the
Company's layers of exposure, consistent with the nature of excess casualty
insurance.
 
  The 1998 current year losses reflect the inclusion of the operations of Mid
Ocean acquired on August 7, 1998. The results include four months of XLMORe and
three months of Brockbank. These operations incurred $169 million in gross
losses for the reported period. These losses were largely attributable to
Hurricane Georges and the SwissAir airline disaster. In addition, losses for
Brockbank attach at the primary layers and therefore are more frequent in
nature. Brockbank's losses are also significantly reinsured.
 
  Prior year incurred losses in 1998 were affected in part, by the release of
insurance reserves established for the Company's professional lines. These
reserves were reduced in accordance with actuarial estimates. In addition,
reserves were released on certain specialty cover policies for the years 1995
through 1997 due to the absence of losses that would affect the Company's
layers. These policies were for a three-year period, written on a claims made
basis and expired in 1998.
 
  Due to the nature of the Company's general liability policy form and the
level of coverage provided, with limits up to $200 million, adjustments to
reserves for individual years can be irregular and significant. Such
adjustments are part of the normal course of business for the Company.
Conditions and trends that have affected development of liability in the past
may not necessarily occur in the future. Accordingly, it is inappropriate to
extrapolate future redundancies or deficiencies based upon historical
experience. See generally "Management's Discussion and Analysis of Results of
Operations and Financial Condition--Cautionary Note Regarding Forward-Looking
Statements."

Claims Administration
 
  All claims management activities are conducted by each insurance subsidiary
of the Company at such subsidiary's offices. Claims management includes the
review of initial loss reports, creation of claims files, administration of
claims data base, generation of appropriate response to claims reports,
including identification and handling of coverage issues, determination of
whether further investigation is required and, where appropriate, retention of
claims counsel, establishment of case reserves, payment of claims, and
notification to reinsurers.
 
  Claims arising from contracts written by the Company's reinsurance
subsidiaries are managed in Bermuda by their own claims departments. Loss
notifications are received from brokers, reviewed and entered into a claims
database and loss reserves are established for the reinsurer's share of the
loss. Loss reserves are adjusted based on receipt of further notifications from
brokers. The claims handled by the Singapore branch are done in a similar
manner at that location.
 
  Claims in respect of business written by corporate syndicate 1209 and
XLMORe's London branch are entered into a claims database maintained at each
location. Losses are primarily notified by various central market bureaus, such
as through a daily electronic data interchange message. Where a syndicate is a
"leading" syndicate on a Lloyd's policy, it will act with its underwriters and
claims adjusters in dealing with the broker or insured on behalf of itself and
the following market in dealing with the broker or insured for any particular
claim. This may involve appointing attorneys or loss adjusters. The claims
bureaus and the leading syndicate advise movements in loss reserves to all
syndicates participating on the risk. The claims departments can vary the case
reserves it records from those advised by the bureaus and all adjustments are
recorded on the claims system.
 
  Claims in respect of the direct motor business written by corporate syndicate
2253 are handled by Admiral Insurance Services ("Admiral") at two tele-
servicing centers in Cardiff and Swansea, Wales. The majority of accidental
damage claims are handled by Admiral's national network of 135 approved repair
centers, most of which have direct video links with Admiral's in-house
engineering team. Personal injury cases are handled by a team of in-house
specialists who, where necessary, appoint attorneys from a preferred panel.
 
Investments
 
  The Finance Committee of the Board of the Company and management oversee
investment strategy, establish guidelines for the various investment managers
and implement investment decisions with the assistance of such managers. The
current investment policy is based on a total return strategy and seeks to
maximize investment income through a high-quality, diversified portfolio while
focusing on preserving principal and maintaining liquidity. In this regard, at
November 30, 1998, the Company's fixed income investment portfolio included
U.S. and non-U.S. sovereign government obligations, corporate bonds and other
securities, 58% of which were rated Aa or AA or better by a nationally
recognized rating agency. Under current investment guidelines, up to 30% of the
Company's investment portfolio may be invested in equity securities. Applicable
insurance laws and regulations generally 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
financial requirements. The Company's U.S. insurance subsidiaries and Brockbank
are subject to restrictions on investment prescribed by laws applicable to such
operations. At each of November 30, 1998, 1997 and 1996, 11%, 19% and 14% of
the Company's investments in fixed maturity and short-term investments and 34%,
42% and 45% of the Company's investments in equity securities were represented
by securities of non-U.S. issuers. The Company did not have an aggregate
investment in a single entity (other than the U.S. government) in excess of 10%
of total consolidated shareholders' equity at November 30, 1998, 1997 or 1996.

Regulation
 
 Bermuda
 
  The Insurance Act 1978 of Bermuda, amendments thereto and related
regulations (the "Act"), regulates the business of XLI and XLMORe. The Act
imposes on Bermuda insurance companies solvency and liquidity standards and
auditing and reporting requirements and grants to the Minister of Finance
powers to supervise, investigate and intervene in the affairs of insurance
companies. XLI and XLMORe are designated as Class 4 insurers under the Act
because they carry on insurance and reinsurance business including excess
liability business and property catastrophe reinsurance business,
respectively. Class 4 insurers are required to maintain total statutory
capital and surplus of not less than $100 million. Both companies are
restricted from paying dividends in any one financial year in excess of 25% of
the prior year's statutory capital and surplus unless the companies' directors
attest such dividends will not cause the companies to fail to meet their
relevant margins. As both companies are highly capitalized, they are not
materially affected by this requirement. In addition to other regulatory
requirements, each Class 4 insurer is required to appoint a loss reserve
specialist, who must be approved by the Minister of Finance of Bermuda, to
review and report on the loss reserves of the insurer on an annual basis.
Other subsidiaries of the Company based in Bermuda, including XLFA, LARe and
Reeve Court, are also subject to regulation under the Act.
 
 Republic of Ireland
 
  XLE is permitted to cover risks throughout the European Community (subject
to certain restrictions) pursuant to the "Third Directive" relating to non-
life insurance. Its operations, however, are largely restricted to the
Republic of Ireland and are subject to regulation under Irish regulatory
authority. The principal legislation and regulations governing the insurance
activities of Irish insurance companies are the Companies Act of 1963 to 1990
and a range of Irish Insurance Acts from 1909 through 1995 (the "Irish Acts").
In addition, there is a comprehensive network of regulations and statutory
provisions empowering the making of regulations of which the most relevant are
the European Communities (Non-Life Insurance) Framework Regulations, 1994, the
European Communities (Insurance Undertakings Accounts) Regulations, 1996 and a
range of other European Communities Regulations and administrative rules (the
"Irish Regulations").
 
  XLE's insurance activities are subject to extensive regulation in the
Republic of Ireland, principally under the Irish Acts and Irish Regulations,
which impose on insurers headquartered in the Republic of Ireland minimum
solvency and reserve standards and auditing and reporting requirements and
grant to the Minister for Enterprise, Trade and Employment (the "Irish
Minister") wide powers to supervise, investigate and intervene in the affairs
of such insurers. The Irish Minister's powers and functions are exercised
through the Department of Enterprise, Trade and Employment.

 United States
 
  The Company's U.S. insurance subsidiaries are subject to regulatory oversight
under the insurance statutes and regulations of the jurisdictions in which they
conduct business, including requirements as to premium rates and policy forms,
adequacy of reserves, types and quality of investments, dividends and changes
of control. Any entity wishing to acquire more than 10 percent of the voting
securities of the Company would require prior regulatory approval from one or
more U.S. state insurance regulatory authorities. Brockbank, via Lloyd's, is
licensed in the states of Illinois and Kentucky and in the U.S. Virgin Islands
("USVI"). It is also an eligible surplus lines writer in all states other than
Kentucky and USVI, and an accredited reinsurer in every state other than
Michigan. Brockbank Insurance Services, Inc. is licensed in California as a
surplus and special lines broker.
 
  The insurance laws of each state of the United States and of many foreign
countries regulate the sale of insurance within their jurisdictions by alien
insurers, such as XLI and XLMORe, which conduct their businesses in Bermuda.
The Company believes it and its subsidiaries are not in violation of the
insurance laws of any state in the U.S. or any foreign country. From time to
time, various proposals for federal legislation within the United States have
been circulated which could indirectly require the Company's non-U.S.
subsidiaries to, among other things, register as surplus lines insurers. The
Company believes that generally its subsidiaries could meet and comply with the
requirements to be registered as surplus lines insurers and such compliance
would not have a material impact on the ability of the Company's subsidiaries
to conduct their businesses. There can be no assurance, however, that the
activities of the Company's subsidiaries will not be challenged in the future
or that the Company's subsidiaries will be able to successfully defend against
such challenges or that legislation will not be enacted that will affect its
subsidiaries' ability to conduct their businesses or subject them to additional
U.S. regulation.
 
 United Kingdom
 
  The United Kingdom Financial Services Authority ("UK FSA") regulates
reinsurance entities that are "effecting and carrying on" insurance business in
the United Kingdom. XLMORe, through its London branch, "effects and carries on"
business in the United Kingdom and is therefore regulated by the UK FSA.
 
 Lloyd's
 
  As a result of the Company's ownership of Brockbank, the Company and
Brockbank are subject to the regulatory jurisdiction of the Council of Lloyd's
(the "Council"). Unlike other financial markets in the UK, Lloyd's is not
subject to direct UK government regulation through The Financial Services Act
of 1986 but, instead, is self regulating by virtue of The Lloyd's Act of 1982
through bye-laws, regulations and codes of conduct written 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 and capital providers. Under the regulations, the
approval of the Council has to be obtained before any person can be a "major
shareholder" or "controller" of a corporate Name or a managing agency. The
Company has been approved as both a "major shareholder" and a "controller" of
its corporate Names (the "CCVs") and managing agencies.
 
  A person would be viewed by Lloyd's as a "major shareholder" of the CCVs if
such person owns 15% or more of the Company's outstanding capital stock and as
a "controller" if it owns 30% or more of the Company's outstanding capital
stock. Therefore, any person that becomes the owner of 15% 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.
 
                                       17
<PAGE>
 
  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 relevant managing agency, but there are no
provisions in The Lloyd's Act of 1982, the bye-laws or the regulations which
provide for any liabilities of the CCVs or the Brockbank group as a whole 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. The CCVs, as corporate members of Lloyd's, are each
required to commit a specified amount approximately equal to 50% of their
underwriting capacity on the syndicates to support its underwriting on those
syndicates.
 
  The Lloyd's Act of 1982 generally restricts certain direct or indirect equity
cross-ownership between a Lloyd's broker and a Lloyd's managing agent.
 
 Other
 
  The Company is subject to regulation in Australia, Singapore and Germany as a
result of its representative offices and branches in such jurisdictions. The
Company or its subsidiaries also may become subject to regulation in
jurisdictions not described herein from time to time based on their activities.
 
Tax Matters
 
 Corporate Income Tax
 
  The Company is a Cayman Islands corporation and, except as described below,
neither it nor its non-U.S. subsidiaries have ever paid United States corporate
income taxes (other than withholding taxes on dividend income) on the basis
that they are not engaged in a trade or business in the United States; however,
because definitive identification of activities which constitute being engaged
in trade or business in the United States is not provided by the Internal
Revenue Code of 1986 (the "Code"), regulations or court decisions, there can be
no assurance that the Internal Revenue Service ("IRS") will not contend that
the Company or its non-U.S. subsidiaries are engaged in trade or business in
the United States. If the Company or its non-U.S. subsidiaries were considered
to be engaged in trade or business in the United States (and, if the Company or
such subsidiaries were to qualify for the benefits under the income tax treaty
between the United States and Bermuda or the Republic of Ireland, such
businesses were attributable to a "permanent establishment" in the United
States), the Company or such subsidiaries could be subject to U.S. tax at
regular tax rates on its taxable income that is effectively connected with its
U.S. trade or business plus an additional 30% "branch profits" tax on such
income remaining after the regular tax, in which case there could be a material
adverse effect on the Company's shareholders' equity and earnings.
 
  Lloyd's names are required to pay U.S. income tax on U.S. connected income
("U.S. income") written by Lloyd's syndicates in which they participate.
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. The CCVs are subject to this
arrangement but, as UK domiciled companies, will receive U.K. corporation tax
credits for any U.S. income tax incurred up to the value of the equivalent U.K.
corporation income tax charge.
 
  Certain subsidiaries of the Company and certain branches and offices of such
subsidiaries are located in taxable jurisdictions such as the United States,
the United Kingdom, Ireland, Australia, Singapore and Germany. The Company pays
corporate income taxes and other taxes, including applicable value added and
premium taxes, to which its subsidiaries and their branches and offices are
subject in such jurisdictions.
 
Employees
 
  At November 30, 1998, the Company and its subsidiaries employed a total of
506 employees; of which 181 were located in Bermuda, 261 were located in the
United Kingdom, 43 in the Republic of Ireland, 6 in the United States with the
balance located in the Company's offices in Munich and Singapore. None of the
these employees are represented by a labor union, and the Company believes that
its employee relations are excellent.
 
                                       18
<PAGE>
 
Item 2. Properties
 
  The Company rents space for its principal executive offices under leases
which expire up to June 2009. Total rent expense for the years ended November
30, 1998, 1997 and 1996 were approximately $3.7 million, $2.1 million and $1.8
million, respectively. Future minimum rental commitments under existing leases
are expected to be approximately $4.0 million annually. In 1997, the Company
acquired commercial real estate in Bermuda for the purpose of securing long-
term office space to meet its anticipated needs. The Company is in the process
of developing this property and constructing its worldwide headquarters. The
total cost of this development, including the land, is expected to be
approximately $110.0 million, of which $23.7 million has been spent to date. It
is estimated that the headquarters project will be completed early in 2001.
 
Item 3. Legal Proceedings
 
  The Company, through its subsidiaries, in common with the insurance and
reinsurance industry in general, is subject to litigation in the normal course
of its business. Although most of its insurance policies provide for resolution
of disputes by arbitration in London, XLI has been sued several times in United
States courts and is defending each suit vigorously, both on procedural grounds
and the merits. As of November 30, 1998, the Company was not a party to any
material litigation other than as routinely encountered in claims activity,
none of which is expected by management to have a material adverse effect on
the Company's financial condition.
 
  The Company, Mid Ocean and the directors of Mid Ocean have been named as
defendants in a purported class action lawsuit (the "Shareholder Action") filed
in connection with the Arrangements in the Supreme Court, County of New York,
State of New York (the "Supreme Court"). Harbor Finance Partners v. Newhouse,
et al., C.A. No. 1998/601266. The Shareholder Action alleges that the
defendants breached their fiduciary duties to the Mid Ocean shareholders by
failing to exercise independent business judgment (due to their alleged
conflict of interest) and by agreeing to sell Mid Ocean at an unfair and
inadequate price. The Shareholder Action is brought on behalf of a purported
class of persons consisting of Mid Ocean shareholders other than the
defendants. As relief, the Shareholder Action seeks, among other things, an
order enjoining consummation of the Arrangements, or, in the event the
Arrangements are consummated, rescission of the Arrangements, and an award of
compensatory damages in an unspecified amount, as well as costs, including fees
for plaintiff's counsel and experts' fees and expenses. On January 25, 1999,
the Supreme Court granted the defendants' motion to dismiss the Shareholder
Action on the grounds that the Shareholder Action (i) failed to state a claim
upon which relief may be granted under Cayman Islands law and (ii) was not
brought in an appropriate forum (forum non conveniens). The Supreme Court's
decision is subject to appeal.
 
Item 4. Submission of Matters to a Vote of Security Holders
 
  No matters were submitted to a vote of stockholders during the fourth quarter
of the fiscal year covered by this report.

        4th Quarter.............................................  77.688  62.125
</TABLE>
 
  Each Class A Ordinary Share has one vote, except that if, and so long as, the
Controlled Shares of any person constitute ten percent (10%) or more of the
issued Class A Ordinary Shares, the voting rights with respect to the
Controlled Shares owned by such person shall be limited, in the aggregate, to a
voting power of approximately ten percent (10%), pursuant to a formula
specified in the Articles of Association. "Controlled Shares" shall include,
among other things, all Class A Ordinary Shares for which such person is deemed
to beneficially own directly, indirectly or constructively (within the meaning
of Section 13(d)(3) of the Securities Exchange Act of 1934).
 
  (b) The approximate number of record holders of Class A Ordinary Shares as of
November 30, 1998 was 360.
 
  (c) The Company paid four regular quarterly dividends in 1997, three of $0.32
per share to shareholders of record at February 6, April 22 and July 11 and one
of $0.40 per share to shareholders of record at September 25.
 
  The Company paid four regular quarterly dividends in 1998, three of $0.40 per
share to shareholders
of record on February 6, April 16 and July 15 and one of $0.44 per share to
shareholders of record on
September 28.
 
  The declaration and payment of future dividends by the Company will be at the
discretion of the Board of Directors and will depend upon many factors,
including the Company's earnings, financial condition, business needs, the
capital and surplus requirements of the Company's operating subsidiaries and
regulatory considerations.
 
  As a holding company, the Company's principal source of income is dividends
or other statutorily permissible payments from its subsidiaries. The ability to
pay such dividends is limited by the applicable insurance laws and regulations
of Bermuda, the United States and the United Kingdom, including those
promulgated by the Society of Lloyd's. In order to pay dividends, the amount of
which is limited to accumulated net realized profits, XLI and XLMORe must
maintain certain minimum levels of share capital, solvency and liquidity
pursuant to Bermuda statutes and regulations. At November 30, 1998, XLI and
XLMORE could have paid dividends in the amount of approximately $1.8 billion
and $1.3 billion, respectively. Neither the Company nor any of its material
subsidiaries other than XLI, XLMORe, XLE, XLIA or XLRS had any other
restrictions preventing them from paying dividends. No assurance, however, can
be given that the Company or its subsidiaries will not be prevented from paying
dividends in the future.
 
  (d) Rights to purchase Class A Ordinary Shares were distributed as a dividend
at the rate of one Right for each outstanding Class A Ordinary Share held of
record as of the close of business on October 31, 1998. Each
 
                                       22
<PAGE>
 
Right will entitle holders of XL Class A Ordinary Shares to buy one ordinary
share at an exercise price of $350.00. The Rights would be exercisable, and
would detach from the Class A Ordinary Shares, only if a person or group were
to acquire 20 percent or more of XL's outstanding Class A Ordinary Shares, or
were to announce a tender or exchange offer that, if consumated, would result
in a person or group beneficially owning 20 percent or more of XL's Class A
Ordinary Shares. Upon a person or group without prior approval of the Board
acquiring 20 percent or more of XL's Class A Ordinary Shares, each Right would
entitle the holder (other than such an acquiring person or group) to purchase
XL Class A Ordinary Shares (or, in certain circumstances, Class A Ordinary
Shares of the acquiring person) with a value of twice the Rights exercise
price upon payment of the Rights exercise price, XL will be entitled to redeem
the Rights at $0.01 per Right at any time until the close of business on the
tenth day after the Rights become exercisable. The Rights will expire at the
close of business on September 30, 2008, and do not initially have a fair
value. The Company has initially reserved 119,073,878 Class A Ordinary Shares
being authorized and unissued for issuance upon exercise of the Rights.
 
  (e) On November 3, 1998, the Company issued 1,066,667 Class A Ordinary
Shares to FSA in connection with entering into the FSA Joint Venture. The
consideration for the Class A Ordinary Shares was common stock of FSA. The
transaction was exempt from the registration requirements of the Securities
Act of 1933 by virtue of the exemption provided under Section 4(2) of such
Act.

  Both net earned premiums and net investment income increased significantly in
1998 over 1997, compared to the change from 1996 to 1997. These results were
affected by the Company's acquisition of GCR in June 1997 and the merger with
Mid Ocean in August 1998. Accordingly, such growth may not be indicative for
future periods.
 
  Mid Ocean prior to the acquisition was an affiliate of the Company.
Consequently, the equity in net earnings from affiliates only reflects the
Company's share of Mid Ocean's earnings for the first nine months of 1998.
Subsequent results for Mid Ocean are now consolidated.
 
  The Company is effectively organized into three business operations:
insurance, reinsurance and Lloyd's Syndicates.
 
  The insurance business is written primarily by XLI, based in Bermuda, and its
subsidiaries, XLE, based in Dublin, Ireland, XLIA and XLRS, based in New York
and Connecticut, respectively. The insurance operations are leading providers
of high excess coverage for general third party liability, other liability,
including directors and officers, professional and employment practices
liability, property and other specialty covers.
 
  The reinsurance business is written primarily by XLMORe, based in Bermuda,
with branch operations in London and Singapore and an office in Munich. It also
has controlling ownership of LARe. MORe, a subsidiary of Mid Ocean, was
acquired by merger on August 7, 1998, and was amalgamated with XLGRe. The
reinsurance group is a leading writer of property catastrophe, other property,
including property excess of loss and property pro rata, marine and energy,
aviation and satellite and specialty liability and other covers.
 
  The Lloyd's operations are managed by Brockbank which provides underwriting
and other services to five Lloyd's syndicates, two of which are dedicated
corporate syndicates whose capital is provided by the Company. These syndicates
write property, marine and energy, aviation and satellite, professional
indemnity, motor and other specialty lines primarily of insurance but also
reinsurance, to a globally diverse group of clients. The Brockbank operations
were acquired through the merger with Mid Ocean. The results of Brockbank are
only included in the Company's 1998 fourth quarter. Premiums written for the
first nine months relate to the Company's interest in Venton Holdings Limited
("Venton"). The Company's interest in Venton was sold in the fourth quarter of
the Company's 1998 fiscal year.

  The growth in gross and net premiums written and net premiums earned have
been affected by the Company's acquisitions (as discussed previously), the
development of new product lines and the ability to maintain a relatively high
level of policy retention despite the highly competitive environment that the
Company and its subsidiaries operate in.
 
  The increase in gross premiums written of $356.6 million in 1998 compared to
1997 was caused by several factors. The level of multi-year premiums written
increased in 1998 compared a decline in such business in 1997. The 1997 fiscal
year was negatively affected by several multi-year property catastrophe
contracts which were rewritten during the year resulting in the return of
premiums written for future years that had not yet been collected or earned.
This also resulted in a reduction of premiums receivable and unearned
premiums.
 
  Additionally, as previously mentioned, the growth in gross premiums written
was affected by the acquisitions of GCR and Mid Ocean. The 1998 year includes
a full year of GCR's premiums compared to five and a half months in 1997, plus
four months of Mid Ocean results and three months of Brockbank results. The
GCR and Mid Ocean premiums are included under Reinsurance Operations and the
Brockbank premiums are included under Lloyd's Syndicates.
 
  Property catastrophe premiums through the first nine months of 1998 reflect
business assumed primarily by XLGRe prior to its amalgamation with MORe while
premiums thereafter reflect the combined MORe and XLGRe. Other reinsurance
represents specialty liability reinsurance related primarily to tailored
programs written by XLI.
 
  Premiums written by Lloyd's Syndicates for the first nine months of the
year, approximately $25 million gross and $7 million net, relate solely to the
Company's interest in Venton. As mentioned previously, Venton was sold in the
fourth quarter of 1998. Accordingly, all results from Lloyd's Syndicates from
the fourth quarter of 1998 and forward are attributable to Brockbank.
 
  Gross premiums written in 1998 and 1997 were also affected by a significant
decline in premiums written for general liability insurance. The Company
continues to experience high levels of competition, particularly on a price
basis and coverage terms, although business retention has remained in excess
of 80%. Policy retention for general liability insurance was 86.1% in 1998
compared to 80.1% in 1997 and 87.9% in 1996. The Company's response has been
to move generally to higher attachment levels which results in lower premiums
as the Company moves further away from risk. As at November 30, 1998, the
average limits for general liability insurance was $84.4 million in excess of
$135.2 million attachment point, as compared to average limits of $86.4
million and $80.2 million in excess of attachment points of $104.0 million and
$78.7 million for the years ended November 30, 1997 and 1996, respectively.
 
  Other liability insurance (comprising mostly professional lines), increased
significantly primarily as a result of several tailored multi-year programs
written in the year. These transactions tend to be complex in nature and often
take a significant period of time to structure, thus premiums written in any
given year may not be representative of future years and/or may be irregular
in nature.
 
  The growth in net premiums written (gross premiums net of reinsurance ceded)
in 1998 over 1997 was likewise affected by the above mentioned factors. In
addition, the Insurance Operations purchased general liability excess of loss
reinsurance contract for $33.8 million at the beginning of the Company's 1997
fourth quarter resulting in a reduction of net premiums written. Such
reinsurance was extended to the Company's year end and has been renewed for
1999. There was no equivalent reinsurance for 1996.
 
 
                                      26
<PAGE>
 
  The increase in net premiums earned reflects the corresponding growth in net
premiums written. Unlike net premiums written, the timing differences created
by the writing of multi-year premiums are smoothed as net premiums are earned
over the lives of the policies. Thus net earned premiums earned may give a
better indication of the trends in the Company's underlying business.

Net investment income........................ $279,375 $216,552 $198,598
</TABLE>
 
  The increase in net investment income in 1998 over 1997 is due to a number
of factors. The average asset base increased primarily due to the merger with
Mid Ocean during the third quarter of 1998 and the Company's positive
operational cash flow. In addition, the average yield of the portfolio was
higher due to a widening of interest spreads and a decrease in the
proportionate amount of equity securities held as a percentage of the total
investment portfolio.
 
  Similarly, in 1997, the average asset base increased with the acquisition of
GCR. Average investment yields were also higher than 1996. The proportion of
equity securities relative to the fixed income portfolio decreased marginally
in 1997 compared to 1996.

Net realized investment gains....................... $191,795 $335,939 $206,212
</TABLE>
 
  Gains realized in 1998 reflected the strong performance of both the equity
and certain sectors of the fixed income markets early in 1998, offset by
dramatic price declines in the third quarter, followed by recoveries in the
fourth quarter. Regarding the latter, generally declining interest rates and
sector volatility have resulted in spreads widening in the corporate and
mortgage markets, thereby providing the Company with opportunities to increase
the yield on its investments despite the general decline in interest rates.
Also, volatile markets may promote opportunities for the Company's investment
managers to pursue their total return objectives with a goal of generating
investment gains in the process.
 
  The equity markets world-wide have remained strong but also have been
subject to greater volatility through the year. This resulted in $136.7
million in gains being realized as some of the Company's equity managers
locked in gains where they felt valuations had reached their targets. The
Company also sold its minority investment in Venton during the fourth quarter,
realizing a $14.1 million gain.
 
  During 1997, both the fixed income and equity portfolios were restructured,
resulting in above normal turnover of the portfolio and contributing to the
significant gains realized during the year. Market conditions were also very
strong during 1997. The Company also maintains a synthetic equity portfolio
holding S&P 500 Index futures that realized net gains of $25.8 million and
$37.4 million for the years ended November 30, 1998 and 1997, respectively.

Equity in net income of affiliates..................... $47,980 $65,882 $59,249
</TABLE>
 
  Equity in net income from affiliates was derived mostly from the Company's
equity position in Mid Ocean, which ended in August 1998 upon the acquisition
of the balance of the outstanding Mid Ocean shares. As a result, only nine
months of earnings were accounted for on this basis in 1998, compared to a
full year in 1997.
 
 
                                      27

  The increase in equity in net income of affiliates in 1997 over 1996
reflected an improvement in reported earnings of Mid Ocean plus contributions
of $3.9 million from the Company's equity positions in Risk Capital Holdings,
Inc. and certain limited partnerships. No positive contributions were recorded
from these affiliates in 1998.

  Approximately one half of all fee income represents net managing agency
income for fees earned by Brockbank and are only for one reported quarter in
1998. These fees are received from the management of Lloyd's syndicates, and
profit commissions are earned under GAAP based upon estimated results of the
syndicates managed. Profit commissions are settled and paid to the managing
agent after an underwriting year has been closed under Lloyd's rules, which is
normally three years after its inception.
 
  Of the remaining balance, $2.2 million represents a fee to the Company's
insurance operations for structuring a specialty insurance cover and $3.6
million represents a distribution from one of its limited partnership
investments.

</TABLE>
 
  The decrease in the loss ratio primarily reflects the diversification of the
Company's business over the past two years to include a lower proportion of
liability business, which tends to be long-tail in nature. Loss ratios for this
longer tail business can be higher but usually pay out claims over several
years. The Company experienced lower losses in shorter tail lines resulting in
an overall lower loss ratio. The decrease in the proportion of longer tail
business will cause overall Company loss ratios to decrease in periods of low
catastrophic activity. It should also be noted that the converse may also
occur.
 
  The 1998 year reflects a full year of the results of GCR acquired in June
1997 and four months of MORe acquired in August 1998. Most of the business
written by these companies is short tail in nature.
 
  The 1998 loss ratio was also affected by the reduction of insurance reserves
established for the Company's professional lines to bring them in line with
updated actuarially determined reserve estimates. The Company generally
attempts to take a conservative stance with respect to initial reserves,
particularly on new lines of business due to the limited loss development the
Company would have experienced to date and the long tail nature of certain
lines of cover. In addition, reserves were reduced on specialty cover policies
for the years 1995 through 1997 due to the absence of losses on these policies.
These policies were for a three-year period, written on a claims made basis,
and expired in 1998.
 
  During the fourth quarter of 1998 the Company incurred reinsurance losses of
$63 million relating to Hurricane Georges and the SwissAir airline disaster.
These losses were offset in part by reserves accrued during the year that were
transferred to the Company through the merger with Mid Ocean.
 
  Prior to the acquisition of GCR, reinsurance business was not a significant
component of the Company's total book of business. As the relative proportion
of this business increased, the loss ratio decreased for the reasons explained
above resulting in a lower loss ratio in 1997 over 1996.
 
 
                                       28

  The increase in the expense ratio reflects the change in the Company's
business mix. The reinsurance and Lloyd's syndicate businesses typically have
higher acquisition costs than the Company's insurance business.
 
  The underwriting expense ratio excludes interest costs, the amortization of
intangible assets and one time charges totaling $17.5 million associated with
the realignment of the Company's reinsurance systems and operations. XLGRe and
MORe were amalgamated in August 1998, requiring the merging of data from two
different underwriting systems to effectively monitor the spread of geographic
and other risks. This also required the conversion of all the contracts on one
system to the other. Duplicate office facilities were closed and their
associated capitalized costs were expensed. The Company's severance costs
relating to redundant staff were expensed as well as certain professional
expenses incurred in connection with the merger.

</TABLE>
 
  Net income for 1998 decreased over 1997 which had increased over 1996
primarily due to the amount of investment gains realized in 1997 compared to
1998 and 1996. The increase in income before realized gains and the other
disclosed charges in 1998 and 1997 reflect the Company's acquisitions of Mid
Ocean on August 7, 1998 and GCR on June 12, 1997. Earnings per share were also
affected by the weighted average number of shares outstanding. On a diluted
basis, these were 94,785,000 shares for 1998, 86,314,000 shares for 1997 and
91,328,000 for 1996. The decrease in the weighted average number of shares
outstanding in 1997 reflects the repurchase of shares in 1996 and 1997. The
increase in the number of shares for 1998 is primarily due to the issue of
shares in exchange for Mid Ocean Limited shares.
 
Financial Condition and Liquidity
 
  As a holding company, the Company's assets consist primarily of its
investments in the stock of its subsidiaries, and the Company's future cash
flows depend on the availability of dividends or other statutorily permissible
payments from its subsidiaries. The ability to pay such dividends is limited
by the applicable laws, rules and regulations of Bermuda, the United States,
the Republic of Ireland and the United Kingdom insurance law and regulations,
including those promulgated by the Society of Lloyd's. In order to pay
dividends, the amount of which is limited to accumulated net realized profits,
XLI and XLMORe must maintain certain minimum levels of share capital, solvency
and liquidity pursuant to Bermuda statutes and regulations. At November 30,
1998, XLI and XLMORe could have paid dividends in the amount of approximately
$1.8 billion and $1.3 billion, respectively. Neither the Company nor any of
its material subsidiaries other than XLI, XLMORe, XLE, XLIA and XLRS had any
other restrictions preventing them from paying dividends. No assurance,
however, can be given that the Company or its subsidiaries will not be
prevented from paying dividends in the future. The Company's shareholders'
equity at November 30, 1998 was $4.8 billion, of which $2.4 billion was
retained earnings.
 
  At November 30, 1998, total investments and cash net of unsettled investment
trades was $6.4 billion, compared to $4.3 billion at November 30, 1997. The
increase is due to the acquisition of cash and investments included in the
merger with Mid Ocean, as well as the reinvestment of investment income and
realized gains and
 
                                      29
<PAGE>
 
the strengthening of the bond and equity markets during the year. However, as
the Company's long-tail casualty insurance business matures over the next
three to five years, it is possible that claims payments may increase due to
the increased exposure to events which occurred in prior years but have not
yet been reported or paid. It is also possible that funds available for
investment will be reduced as compared to prior years due to potential
increased claims payments. The Company's fixed income investments (including
short-term investments and cash equivalents) at November 30, 1998 represented
approximately 83% of invested assets and were managed by several outside
investment managers with different strategies. Of the fixed income securities,
83% are of investment grade, with 58% rated Aa or AA or better by a nationally
recognized rating agency. The average quality of the fixed income portfolio
was AA-.
 
  The payable for investments purchased has increased from $382.3 million at
November 30, 1997 to $526.4 million at November 30, 1998. This increase
results from timing differences as it is the Company's policy to account for
its investments on a trade basis.
 
  In fiscal 1996, 1997 and 1998, the total amount of losses paid by the
Company was $302.6 million, $267.2 million and $366.5 million respectively.
 
  The Company establishes reserves to provide for the estimated expenses of
settling claims, the general expenses of administering the claims adjustment
process and for losses incurred but not reported. These reserves are
calculated by using actuarial and other reserving techniques to project the
estimated ultimate net liability for losses and loss expenses. The Company's
reserving practices and the establishment of any particular reserve reflect
management's judgement concerning sound financial practice and does not
represent any admission of liability with respect to any claims made against
the Company's subsidiaries. No assurance can be given that actual claims made
and payments related thereto will not be in excess of the amounts reserved.
 
  Inflation can have an effect on the Company in that inflationary factors can
increase damage awards and potentially result in more claims exceeding
applicable minimum attachment points. The Company's underwriting philosophy is
to adjust premiums in response to inflation, although this may not always be
possible due to competitive pressure. Inflationary factors are considered in
determining the premium level on multi-year policies at the time contracts are
written. In addition, the Company from time to time evaluates whether minimum
attachment points should be raised to take into account inflationary factors.
 
  The Company commenced its initial stock repurchase program in September 1993
as authorized by its Board of Directors and obtained approval for subsequent
programs as each program was completed. On January 24, 1997, the Board of
Directors authorized the Company to repurchase 3 million shares as
circumstances warrant. As at November 30, 1997, the Company had purchased
595,000 shares at cost of $25.3 million. On March 13, 1998, the Board of
Directors discontinued this program with 2.4 million shares remaining and
replaced it with an authorization to repurchase $500 million of its shares. Of
this amount, $300 million was used to repurchase 3.7 million shares related to
the merger with Mid Ocean. In addition, the Company had purchased a further
732,000 shares at a cost of $51.2 million during the year. On January 22,
1999, the Board of Directors discontinued this program with $148.8 million
remaining and replaced it with an authorization to repurchase $500 million of
its shares.
 
  On June 11, 1997, subsidiaries of the Company obtained two revolving lines
of credit each for $250 million, one for 364 days and the other for 5 years.
The one-year facility has been extended until June 1999. These facilities are
provided by a syndicate of banks in order to facilitate strategic acquisitions
and to supplement operational cash flow. The weighted average interest rate on
the funds borrowed during 1998 was 5.667%. The balance of the loan outstanding
under the facilities as at November 30, 1998 was $190 million, which was
extended for an additional three months at its due date on December 16, 1998.
This amount represents the balance remaining of $250 million that was borrowed
to fund the cash election option available to shareholders in connection with
the Mid Ocean merger.
 
  Mid Ocean had obtained multi-currency committed lines of credit provided by
a syndicate of banks which provides for unsecured borrowing up to an aggregate
amount of $200 million subject to certain conditions in
 
                                      30
<PAGE>
 
August 1997. The Mid Ocean facility is split evenly between a 364-day and a
5-year facility. These facilities remained in place following the merger with
Mid Ocean. In August 1998, $50 million was borrowed from the 5-year facility
and used by the Company in connection with the purchase of shares as part of
the Mid Ocean merger. This was repaid in November 1998.
 
  In 1998, X.L. America, Inc. ("XLA") obtained an unsecured revolving line of
credit of $100 million for 364 days from a U.S. bank. During the year the full
amount of this facility was borrowed and used to fund the Company's U.S.
operations. This line of credit was replaced in December 1998 with a $150
million commercial paper funding facility of which $100 million has been
drawn. XLI guarantees the indebtedness of XLA under this facility.
 
  On February 27, 1998, subsidiaries of the Company obtained a $500 million
letter of credit facility from a syndicate of banks, which is secured against
the Company's investment portfolio. This facility is used to collateralize
certain reinsured's technical reserves with the Company. The Company has
committed to letters of credit of approximately $80.6 million as at November
30, 1998.
 
  Mid Ocean had a $325 million letter of credit facility with Citibank N.A.,
London Branch, which is secured against its investment portfolio. Letters of
credit totaling approximately $223.0 million under this facility were
outstanding as at November 30, 1998.
 
Year 2000 Considerations
 
  The Company is exposed to risks associated with Year 2000 issues in terms of
both the technology systems on which it depends and the underwriting exposures
which it assumes.
 
  In 1997, the Company initiated a project to address Year 2000 issues with
respect to the Company's computer software and information technology systems
as well as its non-information technology systems. The project has two
distinct areas of focus--assessment of the Year 2000 compliance of the
Company's software, systems and technology platforms, and the evaluation of
the Year 2000 preparedness of significant third parties with whom the Company
conducts business, including vendors and customers.
 
  The Company has substantially completed its assessment of Company software
and systems and has adopted a plan to implement compliant components, targeted
to be substantially complete by June 1999. The Company estimates that through
November 30, 1998 the remediation and validation efforts are approximately 50%
complete, with the costs through such date aggregating approximately $3
million. Future costs of remediation are not expected to have a material
impact on the Company's financial position, results of operation or cash
flows.
 
  The Company recognizes the potential impact of Year 2000 issues from its
service providers and customers. The Company is currently communicating with
its significant service providers to assess their readiness and will address
compliance risks with each new significant vendor. In addition, the Company's
potential exposure to its customers' Year 2000 issues is being reviewed.
Formal contingency plans will not be formulated until the Company has
identified specific areas where there is a substantial risk of Year 2000
problems occurring, and no such areas are identified as of this date.
 
  All insurance and reinsurance subsidiaries of the Company examine the
potential exposure to Year 2000-related risks associated with the coverages
that they provide. In some instances, Year 2000-related risks are expressly
excluded from or included in certain coverages, and in other instances,
coverage in respect of such risks is neither expressly excluded nor included.
To the extent that Year 2000-related risks materialize, participants in the
property and casualty insurance and reinsurance industry, including the
Company, could pay or incur significant claims, losses or defense costs which
could have a material adverse effect on the Company's results of operations
and financial condition. In view of the inherent uncertainties surrounding the
likelihood that Year 2000-related risks will materialize and the extent to
which such risks will result in insurance and reinsurance losses, it is not
possible at this time to estimate the Company's potential exposure, if any, to
claims associated with Year 2000-related issues.

Financial Risk Management
 
  This risk management discussion and the estimated amounts generated from the
sensitivity analyses are forward-looking statements of market risk assuming
certain adverse market conditions occur. Actual results in the future may
differ materially from these projected results due to actual developments in
the global financial markets. The methods used by the Company to assess and
mitigate risk should not be considered projections of future events of losses
or lack of losses.
 
  The Company's investment portfolio consists of fixed income and equity
securities, denominated in both U.S. dollars and non-U.S. currencies.
Accordingly, earnings will be affected by changes in interest rates, equity
prices and foreign currency exchange rates.
 
  An immediate 100 basis point adverse shift in the treasury yield curve would
result in a decrease in total return of 4.6% or $246 million on the Company's
fixed income portfolio as of November 30, 1998.
 
  The Company has short term debt outstanding. Interest rates are LIBOR based.
Accordingly, any changes in interest rates will affect interest expense. The
Company only has open positions on its five year facility. There are three and
a half years remaining before this facility must be renewed.
 
  In evaluating the impact of price changes of the equity portfolio, including
the synthetic portion thereof, the annual volatility (standard deviation
adjusted to an immediate time horizon) of the S&P (Standard and Poor's) Index
and the Morgan Stanley EAFE (European Australia Far East) Index were used as
proxies for U.S. and non-U.S. securities, respectively. Based upon one
standard deviation, total return would be impacted by $12 million. A 10%
change in equity prices would effect total return by approximately $113
million.
 
 Foreign Currency Exposure Management
 
  The Company uses foreign exchange contracts to manage its exposure to the
effects of fluctuating foreign currencies on the value of its non-U.S. dollar
fixed maturities and its non-U.S. dollar equity investments on an overlay
basis. These contracts are not designated as specific hedges for financial
reporting purposes and, therefore realized and unrealized gains and losses
recognized on them are recorded as a component of net realized gains and
losses in the period in which they occur. These contracts generally have
maturities of three months or less. In addition, where the Company's
investment managers are of the opinion that potential gains exist in a
particular currency, a forward contract will not be entered into. At November
30, 1998, forward foreign exchange contracts with notional principal amounts
totaling $322.3 million were outstanding. The fair value of these contracts as
at November 30, 1998, was $308.4 million with unrealized losses of $13.9
million. Gains of $3.8 million were realized during the year. Based on this
value, a 10% appreciation or depreciation of the U.S. dollar as compared to
the level of other currencies under contract at November 30, 1998 would have
resulted in approximately $11.2 million in unrealized gains and $33.2 million
in unrealized losses.
 
  In addition, the Company also enters into foreign exchange contracts to buy
and sell foreign currencies in the course of trading its non-U.S. dollar
investments. These contracts are not designated as specific hedges for
financial reporting purposes, and generally have maturities of weeks or less.
As such, any realized or unrealized gains or losses are recorded in income in
the period in which they occur. At November 30, 1998, the Company had $2.4
million of such contracts outstanding, and had recognized a total of $0.4
million in realized and unrealized losses for the twelve month period. Based
on this value, a 10% appreciation or depreciation of the U.S. dollar as
compared to the level of other currencies under contract at November 30, 1998,
would have had no material effect on income.
 
  The Company attempts to hedge directly the foreign currency exposure of a
portion of its non-U.S. Dollar fixed maturity investments using forward
foreign exchange contracts that generally have maturities of three months or
less, and which are rolled over to provide continuing coverage for as long as
the investments are held. Where an investment is sold, the related foreign
exchange sale contract is closed by entering into an offsetting purchase
contract. At November 30, 1998 the Company had, as hedges, foreign exchange
contracts for the sale of $17.5 million and the purchase of $0.1 million of
foreign currencies at fixed rates, primarily New Zealand Dollars (73% of net
contract value), Danish Kroner (14%) and Swedish Kroner (13%). The market
value of non-U.S. Dollar fixed maturities held by the Company as at November
30, 1998 was $19.0 million.
 
                                      32
<PAGE>
 
  Unrealized foreign exchange gains or losses on foreign exchange contracts
hedging non-U.S. Dollar fixed maturity investments are deferred and included
in shareholders' equity. As at November 30, 1998, unrealized deferred losses
amounted to $0.1 million, and were offset by corresponding decreases in the
dollar value of the investments. Realized gains and losses on the maturity of
these contracts are also deferred and included in shareholders' equity until
the corresponding investment is sold. As at November 30, 1998, realized
deferred losses amounted to $2.0 million.
 
  In January 1999, eleven Member States of the European Union ("EU") began
their participation in the EU's Economic and Monetary Union pursuant to which
participating Member States currencies were converted into the Euro, the
common currency for the EU. The Company is uncertain as to the impact of the
conversion on its business and financial condition and the Company has not yet
initiated a detailed analysis and plan with respect to the Euro. Although the
Company does not anticipate the costs associated with the conversion to be
material, such costs are not known with precision at this time.
 
 Financial Market Exposure
 
  The Company also invests in a synthetic equity portfolio of S&P Index
futures with an exposure approximately equal in amount to the market value of
underlying assets held in this fund. As at November 30, 1998, the portfolio
held $138.3 million in exposure to S&P 500 Index futures together with fixed
maturities, short-term investments and cash amounting to $139.5 million. Based
on this value, a 10% increase or decrease in the price of these futures would
have resulted in a total value, or exposure, of $152.2 million and $124.5
million, respectively. The value of the futures is updated daily with the
change recorded in income as a realized gain or loss. For the year ended
November 30, 1998, net realized gains from index futures totalled $25.8
million as a result of the 21.5% increase in the S&P Index during the twelve-
month period.
 
  Derivative investments are also utilized to add value to the portfolio where
market inefficiencies are believed to exist. At November 30, 1998, bond and
stock index futures outstanding were $333.4 million, with underlying
investments having a market value of $2.1 billion (all portfolio managers are
prohibited by the Company's investment guidelines from leveraging their
positions). A 10% appreciation or depreciation of these derivative instruments
at this time would have resulted in unrealized gains and losses of $33.3
million, respectively.
 
Accounting Standards
 
  The Financial Accounting Standards Board ("FASB") issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information",
effective for fiscal years beginning after December 15, 1997. This statement
established standards for reporting information about operating segments in
annual financial statements and requires selected information about operating
segments in interim financial reports issued to shareholders. It also
established standards for related disclosures about products and services,
geographical areas and major customers. Under SFAS 131, operating segments are
to be determined consistent with the way that management organizes and
evaluates financial information internally for making operating decisions and
assessing performance. The Company has not yet assessed the affect of the
adoption of this accounting standard on its consolidated financial statement
disclosures.
 
  FASB issued SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits," effective for fiscal years beginning after December
15, 1997. This Statement revises employers' disclosures about pensions and
other postretirement benefit plans. This standard is expected to have a
minimal impact on the Company's consolidated financial disclosures.
 
  FASB also issued SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities", effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. This Statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. If certain conditions
are met, a derivative may be specifically designated as a hedge.
 
                                      33
<PAGE>
 
The accounting for changes in fair value of a derivative (that is, gains and
losses) depends on the intended use of the derivative and the resulting
designation. The Company has not yet assessed the affect of the adoption of
this accounting standard on its consolidated financial statement disclosures.
SFAS No. 131 and No. 133 are not expected to have a significant impact on the
Company's overall results but will affect the Company's financial statements
and disclosures.
 
Current Outlook
 
  The Company believes competition in the property casualty insurance and
reinsurance industry will continue to be strong and may intensify in 1999,
exerting pressure on rates in general across virtually all property and
casualty product lines. Although the Company believes some opportunities will
exist in 1999 for growth in certain product lines, no assurances can be made
that growth in such product lines will be sufficient to offset the competitive
pressures affecting the Company's other product lines.
 
Cautionary Note Regarding Forward-Looking Statements
 
  The Private Securities Litigation Reform Act of 1995 ("PSLRA") provides a
"safe harbor" for forward-looking statements. This Form 10-K, the Company's
Annual Report to Stockholders, any proxy statement, any Form 10-Q or Form 8-K
of the Company or any other written or oral statements made by or on behalf of
the Company may include forward-looking statements which reflect the Company's
current views with respect to future events and financial performance. Such
statements include forward-looking statements both with respect to the Company
and the insurance and reinsurance sectors in general (both as to underwriting
and investment matters). Statements which include the words "expect",
"intend", "plan", "believe", "project", "anticipate", "will" and similar
statements of a future or forward-looking nature identify forward-looking
statements for purposes of the PSLRA.
 
  All forward-looking statements address matters that involve risks and
uncertainties. Accordingly, there are or will be important factors that could
cause actual results to differ materially from those indicated in such
statements. The Company believes that these factors include, but are not
limited to, the following: (i) ineffectiveness or obsolescence of the
Company's business strategy due to changes in current or future market
conditions; (ii) increased competition on the basis of pricing, capacity,
coverage terms or other factors; (iii) greater frequency or severity of claims
and loss activity, including as a result of natural or man-made catastrophic
events, than the Company's underwriting, reserving or investment practices
anticipate based on historical experience or industry data; (v) developments
in the world's financial and capital markets which adversely affect the
performance of the Company's investments; (vi) changes in regulation or tax
laws applicable to the Company, its subsidiaries, brokers or customers; (vii)
acceptance of the Company's products and services, including new products and
services; (viii) changes in the availability, cost or quality of reinsurance;
(ix) changes in the distribution or placement of risks due to increased
consolidation of insurance and reinsurance brokers; (x) the impact of Year
2000-related issues on the Company's technology systems and underwriting

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
             For the Years Ended November 30, 1998, 1997 and 1996
 
                          (Expressed in U.S. dollars)
 
1. Organization
 
 
  XL Capital Ltd. ("XL" or the "Company") is a holding company organized under
the laws of the Cayman Islands. XL was incorporated on March 16, 1998 as the
successor to EXEL Limited, a Cayman Islands corporation organized in 1986
("EXEL"), in connection with EXEL's merger with Mid Ocean Limited, a Cayman
Islands corporation ("Mid Ocean"). In the merger, which was completed on
August 7, 1998, all of the shares of EXEL and Mid Ocean were exchanged for
shares in the Company pursuant to two schemes of arrangement approved by the
Grand Court of the Cayman Islands in accordance with Section 85 of the
Companies Law (1995 Revision) of the Cayman Islands. The Company operated
under the name "EXEL Limited" from completion of the merger until February 1,
1999, when its current name was approved by the requisite vote of the
Company's shareholders. References herein to "XL" or the "Company" also shall
include EXEL unless the context otherwise requires. Through its subsidiaries,
the Company is a leading provider of insurance and reinsurance, including
coverages relating to certain financial risks, to industrial, commercial and
professional service firms, insurance companies and other enterprises on a
worldwide basis.
 
  XL Insurance Ltd, an insurance company organized under the laws of Bermuda
("XLI"), and its subsidiaries are the Company's principal insurance
subsidiaries. XLI was formed in 1986 in response to a shortage of high excess
liability coverage for Fortune 500 companies in the United States. In 1990,
XLI formed XL Europe Insurance, an insurance company organized under the laws
of the Republic of Ireland ("XLE"), to serve European clients. In 1998, XLI
acquired Folksamerica General Insurance Company (renamed X.L. Insurance
Company of America, Inc.), an insurance company domiciled in the State of New
York and possessing property and casualty insurance licenses in approximately
20 states and reinsurance licenses in approximately 14 states, and formed X.L.
Risk Solutions, Inc., an insurance company domiciled in the State of
Connecticut. XLI also has a representative office in Australia.
 
  The Company's reinsurance operations are conducted primarily through XL Mid
Ocean Reinsurance Ltd, an insurance company organized under the laws of
Bermuda ("XLMORe"), and its subsidiaries. On August 7, 1998, XLMORe was formed
through the merger of X.L. Global Reinsurance Company, Ltd. ("XLGRe") and Mid
Ocean Reinsurance Company Ltd. ("MORe"). XLGRe was formed in November 1997
through the merger of X.L. Reinsurance Company, Ltd. ("XLRe") and Global
Capital Reinsurance Company Limited ("GCRe") following EXEL's acquisition of
GCR Holdings Limited, a Cayman Islands holding company, on June 12, 1997. XLRe
commenced operations on December 1, 1995 to write specialty reinsurance
business. MORe and GCRe were organized in 1992 and 1993, respectively,
initially to write property catastrophe reinsurance following severe
hurricanes which struck the southeastern United States in the late 1980's and
early 1990's. Each of XLRe, MORe and GCRe was organized as an insurance
company under the laws of Bermuda. XLMORe maintains branches in London,
Singapore and a European contact office in Munich.
 
  The Company's operations at Lloyd's are conducted through The Brockbank
Group plc, a company organized under the laws of England, and its subsidiaries
(together, "Brockbank"). Brockbank is a leading Lloyd's managing agency which
manages five Lloyd's syndicates, two of which are dedicated corporate
syndicates ("corporate syndicates") whose capital is provided solely by the
Company and its subsidiaries. Mid Ocean acquired 51% of Brockbank in December
1995 and the remaining 49% in August 1997. The two corporate syndicates, which
commenced operations with effect from January 1, 1996, underwrite property,
marine and energy, aviation, satellite, professional indemnity, U.K. motor and
other specialty lines of insurance and reinsurance to a global client base. In
1998, the aggregate premium limit of the two corporate syndicates was
approximately $340 million, and the total capacity under management by
Brockbank was approximately $900 million. As a managing agency, Brockbank
receives fees and commissions in respect of the underwriting services it
provides to syndicates.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
  In October 1998, the Company sold its 21% interest in Venton Holdings
Limited, a Bermuda holding company for the Venton managing agency group at
Lloyd's (together, the "Venton Group"). Prior to the sale, subsidiaries of the
Company provided reinsurance coverage to the Venton Group, which writes
principally professional indemnity, directors' and officers' liability and
fiduciary liability insurance coverages.
 
  The Company participates in several joint ventures of strategic importance.
In general, the Company has pursued a strategy of entering into joint ventures
with organizations which possess expertise in lines of business that the
Company wishes to enter. The Company's principal joint ventures are in the
areas of financial guaranty insurance, life insurance for high net worth
individuals, Latin American reinsurance, political risk insurance and currency
overlay and related risk management.
 
  In November 1998, the Company entered into a joint venture with Financial
Security Assurance Holdings Ltd., a New York corporation ("FSA"), to write
certain types of financial guaranty insurance and reinsurance. FSA, through
its subsidiaries, is primarily engaged in the business of providing financial
guaranty insurance on asset-backed and municipal obligations. Under the terms
of the joint venture, each of the Company and FSA formed a Bermuda insurance
company in which it was the majority shareholder and made a minority
investment in the company formed by its co-venturer. The Company formed and
maintains majority ownership of XL Financial Assurance Ltd. ("XLFA"). FSA
formed and maintains a majority ownership of Financial Security Assurance
International Ltd. ("FSAI"). Each of XLFA and FSAI has a capitalization of
approximately $100 million. As part of the joint venture, the Company and FSA
exchanged approximately $80 million of each other's stock, following which the
Company owned approximately 6% of the issued and outstanding common stock of
FSA.
 
  In June 1998, the Company formed Reeve Court Insurance Ltd., an insurance
company organized under the laws of Bermuda, as a joint venture with such
company's management for the purpose of providing life insurance to high net
worth individuals. Reeve Court has a total capitalization of approximately
$100 million.
 
  In October 1997, the Company and Risk Capital Holdings, Inc., a Delaware
corporation ("RCHI") which holds all of the outstanding shares of Risk Capital
Reinsurance Company, a Nebraska corporation ("RCRe"), organized LARC Holdings,
Ltd., a Bermuda corporation ("LARC") which holds all of the shares of Latin
American Reinsurance Company, Ltd., a Bermuda insurance company ("LARe"). LARe
has approximately $100 million in shareholders' equity and provides multi-line
reinsurance to the Latin American reinsurance market, concentrating on short-
tail, multi-peril property reinsurance and, to a lesser extent, casualty,
marine, aviation and other lines of reinsurance on both a treaty and
facultative basis. XLMORe owns approximately 75% of the outstanding shares of
LARC. The Company indirectly owns approximately 28% of RCHI.
 
  In March 1997, XLI became a founding shareholder along with RCHI and another
insurance company of Sovereign Risk Insurance Ltd. ("Sovereign"), a Bermuda-
based managing general agency formed to write selected political risk
insurance coverages. The Company owns 40.5% of Sovereign.
 
  In 1996, the Company acquired approximately 28% of Pareto Partners
("Pareto"), a firm which specializes in foreign currency overlay management
and related services. At December 31, 1998, Pareto had approximately $26
billion of assets under management. The Company works closely with Pareto to
develop new products and ventures, including the F/XL foreign currency
protection product offered by XLI.
 
2. Operations
 
 (a) Insurance
 
  The Company, through its subsidiaries XLI, XLE, XLIA and XLRS, is a leading
insurer and provides third party general liability insurance, directors and
officers liability insurance, professional liability insurance, employment
practices liability insurance and other liability insurance including,
property insurance, and other
 
                                      40

                                XL CAPITAL LTD
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
insurance covers, including political risk insurance and financial products.
The liability insurance is written on an excess basis and the loss experience
is characterized as low frequency and high severity. Property is written on a
pro rata as well as an excess basis. Policies written on a pro rata basis can
attach at much lower levels. As a result, loss experience can be higher
frequency and lower severity.
 
  The insurance subsidiaries have a quota share reinsurance policy with
several U.S. reinsurers, of which one is RCRe, covering general liability
risks only. Under the terms of this reinsurance, the Company will cede either
20% or 25% of each risk depending upon the underlying limit written. The
maximum amount recoverable from the reinsurers will be the ceded percentage of
the original policy limit on a per occurrence basis, with an annual aggregate
of 225% of the total premium ceded. No single reinsurer participates in excess
of 20% of the quota share. All the reinsurers are rated, of which the lowest
as rated by S&P is BBB. Effective September 1, 1997, the insurance
subsidiaries entered into an excess of loss casualty catastrophe reinsurance
contract covering all general liability risks. Under the terms of this policy,
the Company is reinsured for $80 million ultimate net loss each occurrence
excess of a per occurrence retention, subject to an annual aggregate retention
of $110 million. The maximum amount recoverable from the reinsurers will be an
annual aggregate of $250 million. For the year ended November 30, 1998, 97.75%
of this reinsurance has been placed with twenty three reinsurers, all of which
are rated. With the exception of two reinsurers, the lowest as rated by S&P is
A-. The other two reinsurers are rated BBB and BB by S&P, representing 3.5%
participation on this program.
 
  Employment practices liability coverage is reinsured on a quota share basis
one third of the first $75 million to a U.S. insurer and cedes the remaining
excess layer of $25 million to a Bermuda based insurer. Both reinsurers are
rated, of which the lowest as rated by A.M. Best is A.
 
  The Company cedes 25% of all property risks to a quota share reinsurance
treaty purchased from several property reinsurers. GCR and MORe were both
participants of this program. All property reinsurers are rated, of which the
lowest as rated by S& P is A-.
 
  XL Risk Solutions and CIGNA Risk Solutions are a coordinated initiative
between XLI and CIGNA Property & Casualty ("CIGNA"). The product provides
combined capacity for traditional casualty and property coverages provided by
XLI or CIGNA. Available capacity by line of coverage is $60 million to $200
million depending upon the lines selected. Attachment levels may, in certain
situations, be provided below traditional stated levels subject to the
underwriting requirements. A quota share arrangement exists between XLI and
CIGNA based on pre agreed percentages by line of coverage for blended covers
written through XL Risk Solutions. These percentages vary from 12.5% to 90%,
but do not exceed XLI's normal capacity on individual lines of cover. XLI may
underwrite an account 100% without CIGNA participation.
 
  Sovereign issues subscription policies with XLI and the other insurance
company each assuming 50% of each policy written. The Company reinsures 10% of
all risks assumed through Sovereign to RCRe.
 
  XLI also offers insurance and reinsurance solutions for complex financial
risks. These include financial insurance and reinsurance, credit enhancement,
swaps and other collateralized transactions for up to $100 million in limits.
While each of these are unique and are tailored for the specific needs of the
insured, they are typically multi-year policies. Due to the nature of these
types of policies, premium volume as well as profit margin can vary
significantly from period to period. The Company has no formal reinsurance
coverage for these risks, but may cede a portion of some policies to third
parties from time to time.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
 (b) Reinsurance
 
  The Company, through XLMORe, is a leading reinsurer writing property
catastrophe, property excess of loss, property pro rata, marine and energy,
aviation and satellite and various other reinsurance to insurers on a
worldwide basis. XLMORe maintains branch offices in London and Singapore as
well as a European contact office in Munich, Germany. The London branch
underwrites marine and energy and aviation risks on a worldwide basis. The
Singapore branch underwrites general reinsurance, treaty and facultative
business.
 
  A significant portion of XLMORe's business underwritten consists of large
aggregate exposures to man-made and natural disasters and generally loss
experience is characterized as low frequency and high severity. This may
result in volatility in the Company's financial results. The Company endeavors
to manage its exposures to catastrophic events by limiting the amount of its
exposure in each geographic zone worldwide and requiring that its property
catastrophe contracts provide for aggregate limits and varying attachment
points.
 
  In August 1998, XLMORe placed $200 million of retrocessional property
catastrophe cover in a combination reinsurance and capital market swap
transaction. The transaction was offered in two tranches and covered the upper
layers, with a remote probability of attachment, of XLMORe's hurricane and
earthquake exposure in the United States and its territories and possessions
in the Caribbean. The risk securitization structure provides retrocessional
cover in financial swap form, with claim recovery triggered by catastrophe
losses actually incurred by XLMORe, rather than by a catastrophe index or
industry size event.
 
  LARe provides multi-line reinsurance to the Latin American market,
emphasizing short-tail, multi-peril property reinsurance and, to a limited
extent, casualty, marine, aviation and other lines of reinsurance.
 
 (c) Lloyd's
 
  The Company's wholly owned subsidiary, Brockbank, is a leading Lloyd's
managing agency which manages five syndicates, two of which are dedicated
corporate syndicates whose capital is solely provided by the Company. These
corporate syndicates write property, marine and energy, aviation and
satellite, motor, professional indemnity and other specialty lines, primarily
of insurance but also reinsurance.
 
3. Significant Accounting Policies
 
 (a) Basis of Preparation
 
  These consolidated financial statements include the accounts of the Company
and all of its subsidiaries and have been prepared in accordance with
accounting principles generally accepted in the United States of America. All
material intercompany accounts and transactions have been eliminated. The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amount 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.
Actual results could differ from those estimates.
 
  The comparative consolidated financial statements are those of EXEL, the
Company's predecessor, as previously discussed in note 1.
 
  Certain amounts in the financial statements for prior years have been
reclassified to conform with the 1998 presentation. All share amounts have
been adjusted for the one-for-one stock dividend paid to shareholders of
record July 26, 1996.
 
  Premiums written are recorded in accordance with the terms of the underlying
policies. Reinsurance premiums assumed are estimated based upon information
received from ceding companies and any subsequent
 
                                      42
<PAGE>
 
                                XL CAPITAL LTD
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
differences arising on such estimates are recorded in the period they are
determined. Premiums are earned on a monthly pro-rata basis over the period
the coverage is provided. Unearned premiums represent the portion of premiums
written which is applicable to the unexpired terms of policies in force.
Premiums written under the multi-year alternate rating methodology may be
subject to a mandatory reinstatement premium in the event of a loss. An asset
is accrued to reflect the obligation of the insured's reinstatement premium
and the premium is earned in accordance with the "with or without" method;
that is, the pricing of the premium is evaluated in terms of a no loss
situation and the resultant premium is earned over the remaining term of the
policy. The balance of the reinstatement premium is earned to the extent of
the loss reaching the full policy limit; that is, in the event of a full limit
loss the balance of the reinstatement premium together with any unearned
premium of the underlying cover would be fully earned. Premiums written and
unearned premiums are presented after deductions for reinsurance ceded to
other insurance companies.
 
  Acquisition costs which vary with and are primarily related to the
acquisition of policies, primarily commissions paid to insurance brokers, are
deferred and amortized over the period the premiums are earned. Future earned
premiums and the anticipated losses and other costs related to those premiums
are also considered in determining the level of acquisition costs to be
deferred.
 
 (c) Reinsurance
 
  In the normal course of business, the Company seeks to reduce the loss that
may arise from events that could cause unfavorable underwriting results by
reinsuring certain levels of risk in various areas of exposure with other
insurance enterprises or reinsurers. Reinsurance premiums ceded and the
commissions recorded thereon are expensed and earned on a monthly pro-rata
basis over the period the reinsurance coverage is provided. For those
reinsurance policies that provide coverage to the Company over the term of the
underlying business, the premiums ceded and commissions recorded thereon are
expensed and earned on a monthly pro-rata basis over the estimated term of
those policies. Amounts recoverable from reinsurers are estimated in a manner
consistent with the claim liability associated with the reinsured policy.
 
 (d) Investments
 
  Investments are available for sale and are carried at fair value. The fair
value of investments is based upon quoted market values where available or by
reference to broker or underwriter bid indications. The net unrealized
appreciation or depreciation on investments is included as a separate
component of shareholders' equity.
 
  Short-term investments comprise investments with a maturity equal to or
greater than 90 days but less than one year.
 
  All investment transactions are recorded on a trade date basis. Realized
gains and losses on sales of investments are determined on the basis of
average cost or amortized cost. Investment income is recognized when earned
and includes interest and dividend income together with the amortization of
premium and discount on fixed maturities and short-term investments.
 
  Financial futures and forward currency contracts are marked to market, with
the corresponding realized or unrealized gain or loss included in income,
except in the instance of forward foreign currency contracts that are used to
hedge currency risks on specific investments. Gains and losses from these
contracts are deferred and included in shareholders' equity until the
corresponding asset is sold.
 
 (e) Foreign Currency Translation
 
  The functional and reporting currency of the Company and its subsidiaries is
U.S. dollars. Monetary assets and liabilities denominated in foreign
currencies are translated at the exchange rate in effect at the balance sheet
 
                                      43
<PAGE>
 
                                XL CAPITAL LTD
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
date with the resulting foreign exchange gains and losses recognized in
income, unless the foreign currency exposure is directly hedged as discussed
in note 3 (d). Revenue and expense transactions are translated at the average
exchange rates prevailing during the year.
 
 (f) Investments in Affiliates
 
  The Company accounts for its investments in affiliates on the equity basis.
 
 (g) Other Investments
 
  The Company accounts for its other investments on a cost basis as it has no
significant influence over these entities. Assets are written down to their
realizable value where there is a permanent decrease in value. Income is
recorded when received.
 
 (h) Amortization of Intangible Assets
 
  Intangible assets recorded in connection with the Company's business
combinations are amortized on a straight-line basis over the expected life of
the related operations acquired. The Company evaluates the recoverability of
its intangible assets whenever changes in circumstances warrant. If it is
determine that an impairment exists, the excess of the unamortized balance
over the fair value of the intangible asset will be charged to earnings.
 
 (i) Losses and Loss Expenses
 
  Unpaid losses and loss expenses includes reserves for unpaid reported losses
and loss expenses and for losses incurred but not reported. The reserve for
unpaid reported losses and loss expenses has been established by management in
consultation with independent legal counsel and ceding companies, and
represents the estimated ultimate cost of events or conditions that have been
reported to or specifically identified by the Company.
 
  The Company recognizes as a component of loss reserves, the loss experience
accounts of insurers for policies written under the applicable multi-year
alternate rating methodology. Such experience accounts are a percentage of
premiums net of related losses paid. Interest is earned on liable amounts and
charged to investment income. In the event the insured cancels the policy, the
return of the experience account is treated as a commutation if previously
notified of a loss, or as a return premium if there has been no loss
notification.
 
  The reserve for losses incurred but not reported has been estimated by
management in consultation with independent actuaries and is based on loss
development patterns determined by reference to the Company's underwriting
practices, the policy form and the experience of the relevant insurance
industries.
 
  Management believes that the reserves for unpaid losses and loss expenses
are sufficient to pay any claims that may penetrate the minimum attachment
point. However, there can be no assurance that losses will not exceed the
Company's total reserves. The methodology of estimating the reserve is
periodically reviewed to ensure that the assumptions made continue to be
appropriate and any adjustments resulting therefrom are reflected in income of
the year in which the adjustments are made.
 
 (j) Statements of Cash Flows
 
  For purposes of the statements of cash flows, cash equivalents include fixed
interest deposits placed with a maturity of under 90 days when purchased.

 (k) Earnings per Ordinary Share and Ordinary Share Equivalent
 
  The Company has adopted Statement of Financial Accounting Standards ("SAFS")
No. 128, "Earnings per Share". SFAS No. 128 replaced primary and fully diluted
earnings per share with basic and diluted earnings per share. Basic earnings
per share is calculated by dividing net income by the weighted average number
of ordinary shares outstanding for each period. Diluted earnings per share
reflects the potential dilution that could occur if the securities to issue
ordinary shares were exercised into ordinary shares. Prior years earnings per
share amounts have been restated to reflect this.

  The 1998 current year losses reflects the inclusion of the operations of Mid
Ocean acquired on August 7, 1998. The results include four months of XLMORe
and three months of Brockbank. These operations incurred $169 million in gross
losses for the reported period. These losses were largely attributable to
Hurricane Georges and the SwissAir airline disaster. In addition, losses for
Brockbank attach at the primary layers and therefore are more frequent in
nature. These losses are also significantly reinsured.
 
  Prior year incurred losses in 1998 were effected in part, by the release of
insurance reserves established for the Company's professional lines. These
reserves were reduced in accordance with actuarial estimates. In addition,
reserves were released on specialty cover policies for the years 1995 through
1997 due to the absence of losses that would affect the Company's layers.
These policies were for a three-year period, written on a claims-made basis
and expired in 1998.
 
  The high level of the 1997 current year incurred losses was due to the fact
that three new 1997 casualty indemnity reserves totaling $145 million were
established. Historically, such losses have not emerged this quickly. Should
actual loss activity prove to be different, these reserves will be adjusted
accordingly.
 
  The 1997 losses were offset by the release of $260 million in reserves that
related to prior years in accordance with actuarial estimates.
 
8. Commitments and Contingencies
 
 (a) Letters of Credit
 
  In February 1998, subsidiaries of the Company established a $500 million
letter of credit facility with a syndicate of commercial banks led by Mellon
Bank N.A. Letters of credit issued under this facility are collateralized by
pledged securities in XLI's fixed maturity investment portfolio. Letters of
credit totalling approximately $80.6 million and $155.8 million were
outstanding as at November 30, 1998 and 1997, respectively.
 
  Mid Ocean had a $325 million letter of credit facility with Citibank N.A.,
London Branch. Letters of credit issued under this facility are collateralized
by pledged securities in Mid Ocean's investment portfolio. This

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
facility remains in place following the merger with Mid Ocean. Letters of
credit totaling approximately $223.0 million were outstanding as at November
30, 1998. This amount includes $169.5 million in respect of the Lloyd's
corporate syndicates which has been issued in lieu of paid in capital.
 
 (b) Financial Instruments with Off-Balance Sheet Risk
 
  The Company invests in derivative instruments, such as foreign currency
forward contracts, and futures for purposes other than trading. These
derivative instruments are used for foreign currency exposure management and
to obtain exposure to specific financial markets.
 
  (i) Foreign Currency Exposure Management
 
    The Company uses foreign exchange contracts to manage its exposure to the
  effects of fluctuating foreign currencies on the value of its non-U.S.
  dollar fixed maturities and its non-U.S. dollar equity investments on an
  overlay basis. The fair value of the Company's non-U.S. dollar denominated
  investments as at November 30, 1998 and 1997 was $535.3 million and $566.1
  million, respectively. These contracts are not designated as specific
  hedges for financial reporting purposes and, therefore, realized and
  unrealized gains and losses recognized on them are recorded as a component
  of net realized gains and losses in the period in which they occur. These
  contracts generally have maturities of three months or less. In addition,
  where the Company's investment managers are of the opinion that potential
  gains exist in a particular currency, then a forward contract will not be
  entered into. At November 30, 1998, forward foreign exchange contracts with
  notional principal amounts totalling $322.3 million were outstanding. The
  fair value of these contracts as at November 30, 1998, was $308.4 million
  with unrealized losses of $13.9 million. Gains of $3.8 million were
  realized during the year.
 
    In addition, the Company also enters into foreign exchange contracts to
  buy and sell foreign currencies in the course of trading its non-U.S.
  dollar investments. These contracts are not designated as specific hedges
  for financial reporting purposes, and generally have maturities of two
  weeks or less. As such, any realized or unrealized gains or losses are
  recorded in income in the period in which they occur. At November 30, 1998,
  the Company had a $2.4 million of such contracts outstanding, and had
  recognized a total of $0.4 million in realized and unrealized losses for
  the year.
 
    The Company attempts to hedge directly the foreign currency exposure of a
  portion of its non-U.S. dollar fixed maturity investments using forward
  foreign exchange contracts that generally have maturities of three months
  or less, and which are rolled over to provide continuing coverage for as
  long as the investments are held. Where an investment is sold, the related
  foreign exchange sale contract is closed by entering into an offsetting
  purchase contract. At November 30, 1998, the Company had, as hedges,
  foreign contracts for the sale of $17.5. million and the purchase of $0.1
  million of foreign currencies at fixed rates, primarily New Zealand dollars
  (73% of net contract value), Danish Kroner (14%) and Swedish Kroner (13%).
  The market value of non-U.S. dollar fixed maturities held by the Company as
  at November 30, 1998 was $19.0 million.
 
    Unrealized foreign exchange gains or losses on foreign exchange contracts
  hedging non-U.S. Dollar fixed maturity investments are deferred and
  included in shareholders' equity. As at November 30, 1998, unrealized
  deferred gains amounted to $0.1 million, and were offset by corresponding
  decreases in the U.S. dollar value of the investments. Realized gains and
  losses on the maturity of these contracts are also deferred and included in
  shareholders' equity until the corresponding investment is sold. As at
  November 30, 1998, realized deferred losses amounted to $2.0 million.
 
    The Company is exposed to credit risk in the event of non-performance by
  the other parties to the forward contracts, however the Company does not
  anticipate non-performance. The difference between the notional principal
  amounts and the associated market value is the Company's maximum credit
  exposure.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
  (ii) Financial Market Exposure
 
    The Company also invests in a synthetic equity portfolio of S&P Index
  futures with an exposure approximately equal in amount to the market value
  of underlying assets held in this fund. As at November 30, 1998, the
  portfolio held $138.3 million in exposure to S&P 500 Index futures together
  with fixed maturities, short-term investments and cash amounting to $ 139.5
  million. The value of the futures is updated daily with the change recorded
  in income as a realized gain or loss. For the year ended November 30, 1998,
  net realized gains from index futures totaled $25.8 million.
 
    Derivative investments are also utilized to add value to the portfolio
  where market inefficiencies are believed to exist. At November 30, 1998,
  bond and stock index futures outstanding were $333.4 million, with
  underlying investments having a market value of $ 2.1 billion. All managers
  are prohibited by the Company's investment guidelines from leveraging their
  positions.
 
 (c) Concentrations of Credit Risk
 
  The Company's investment portfolio is managed by external managers in
accordance with guidelines that have been tailored to meet specific investment
strategies, including standards of diversification which limit the allowable
holdings of any single issue. The Company did not have an aggregate investment
in a single entity, other than the U.S. government, in excess of 10% of
shareholders' equity at November 30, 1998.
 
 (d) Other Investments
 
  The Company has committed to invest in several limited partnerships as part
of its overall corporate strategy. The primary purpose of these partnerships
is to invest capital provided by the partners in various insurance and
reinsurance ventures. The Company had invested $33.3 million and $27.2 million
as at November 30, 1998 and 1997, respectively, with commitments to invest a
further $138.7 million over the next ten years. The Company received income
from its investments of $3.6 million and $4.3 million for the years ended
November 30, 1998 and 1997, respectively. The Company continually reviews the
performance of the partnerships to ensure there is no decrease in the values
of its investments. The Company is a limited partner and, as such, does not
actively participate in the management of the partnerships.
 
 (e) Properties
 
  The Company rents space for its principal executive offices under leases
which expire up to June, 2009. Total rent expense for the years ended November
30, 1998, 1997 and 1996 were approximately $3.7 million, $2.1 million and $1.8
million, respectively. Future minimum rental commitments under existing leases
are expected to be approximately $4.0 million annually. In 1997 the Company
acquired commercial real estate in Hamilton, Bermuda for the purpose of
securing long-term office space to meet its anticipated needs. The Company is
in the process of developing this property and constructing its worldwide
headquarters. The total cost of the development, including the land, is
expected to be approximately $110.0 million, of which $23.7 million has been
spent to date. It is estimated that the development will be completed sometime
in 2001. Upon completion of the headquarters project, it is expected that the
Company's rental commitments will be reduced.
 
9. Credit Agreements
 
  In 1997, subsidiaries of the Company obtained two unsecured revolving lines
of credit of $250 million each, one for 364 days (short-term) and the other
for 5 years (long-term), from a syndicate of nine major international banks
led by Mellon Bank, N.A. During the year, a total of $505.0 million was
borrowed at a weighted average rate of 5.667%. Total interest expense and
facility costs amounted to $9.5 million and $7.18 million for the years ended
November 30, 1998 and 1997, respectively. As at November 30, 1998, the
outstanding balance was $190.0 million drawn under the long-term facility and
is repayable within the next twelve months.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
  On June 27, 1996, the Company borrowed $11.0 million from the Bank of
Bermuda (New York) Limited in order to fund its investment in Pareto Partners,
Inc., an investment management company. The loan is repayable in four years.
During the year the weighted average interest rate charged on the loan was
6.02%. Total interest expense amounted to $0.7 million and $0.7 million for
the years ended November 30, 1998 and 1997 respectively.
 
  Mid Ocean had obtained multi-currency committed lines of credit provided by
a syndicate of nine major international banks led by Chase Manhattan Bank,
N.A. which provides for unsecured borrowing up to an aggregate amount of $200
million subject to certain conditions. The Mid Ocean facility is split evenly
between a 364-day and a 5-year facility. These facilities remained in place
following the merger with Mid Ocean. In August 1998, $50 million was borrowed
from this facility and lent to XL in connection with the merger with Mid
Ocean. This was repaid in November 1998. During this period the weighted
average interest rate charged on the loan was 5.760% and the total interest
expense amounted to $0.7 million.
 
  In 1998, XLA obtained an unsecured revolving line of credit of $100 million
for 364 days from Mellon Bank, N.A. During the year the full amount of this
facility was borrowed at a weighted average rate of 5.898%. Total interest
expense and facility costs amounted to $1.3 million for the year ended
November 30, 1998. As at November 30, 1998, the outstanding balance was $100.0
million and is repayable within the next twelve months. This line of credit
was replaced in December 1998 with a $150 million commercial paper funding
facility provided by the same bank. XLI guarantees the indebtedness of XLA
under this facility.
 
  The credit agreements for all facilities contains various financial and non-
financial covenants. The Company and its subsidiaries were in compliance with
all covenants as at November 30, 1998.

million. On March 13, 1998, the Board of Directors discontinued its existing
share repurchase program and authorized a program for $500 million of the
Company's ordinary shares. In August 1998, $300 million of share repurchases
related to the merger with Mid Ocean. In addition, the Company had purchased a
further 732,000 shares at a cost of $51.2 million during the year.
 
 (c) Stock Plans
 
  The Company's executive stock plan, the "1991 Performance Incentive
Program", provides for grants of non qualified or incentive stock options,
restricted stock awards and stock appreciation rights ("SARs"). The plan is
administered by the Company and Compensation Committee of the Board of
Directors. Stock options may be granted with or without SARs. Grant prices are
established at the fair market value of the Company's common stock at the date
of grant. Options and SARs have a life of 10 years and vest annually over
three years from date of grant.
 
  Restricted stock awards issued under the plan vest over a five year period
from the date of grant. These shares contained certain restrictions, for said
period, relating to among other things, forfeiture in the event of termination
of employment and transferability. As the shares are issued, deferred
compensation equivalent to the difference between the issue price and the
estimated fair market value on the date of the grant is charged to
shareholders' equity and subsequently amortized over the five-year restriction
period. Restricted stock issued under the plan totaled 131,936 shares, 274,300
shares and 120,500 shares in 1998, 1997 and 1996, respectively.
 
  The Company also has stock plans in place for its non-employee directors.
The "Stock and Option Plan", issues non-qualified options to the directors--
4,000 shares at the commencement of their directorship and 2,000 shares each
year thereafter. On December 3, 1997, 5,000 options were granted to each
director. All options vest immediately on grant date. Effective April 11,
1997, all options granted to Non-Employee Directors are granted under the 1991
Performance Incentive Program.
 
  Under this plan, directors may also may make an irrevocable election
preceding the beginning of each fiscal year to defer cash compensation that
would otherwise be payable as his or her annual retainer in increments of
$5,000. The deferred payments are credited in the form of share units
calculated by dividing 110% of the deferred payment by the market value of the
Company's stock at the beginning of the fiscal year. Directors also may elect
to receive their annual retainer in the form of shares with a value equal to
the amount of their annual fee. Shares issued under the plan totaled 2,737,
3,048 and 4,048 in 1998, 1997 and 1996, respectively.
 
  A second stock plan, intended to replace the directors' "Retirement Plan for
Non-Employee Directors", provides for the issuance of share units equal to the
amount that would have been credited to the Retirement Plan, divided by the
market price of the Company's stock on December 1 of each year. These units
receive dividends in the form of additional units equal to the cash value
divided by the market price on the payment date. During 1996 the directors
could elect to convert to this plan. Stock units totaling 5,531, 6,716 and
14,960 were provided for in 1998, 1997 and 1996 respectively.
 
 (d) SFAS 123 pro forma disclosure
 
  The Company has adopted the disclosure-only provisions of Statement of
Financial Accounting Standard No. 123, "Accounting for Stock-Based
Compensation". Had the Company adopted the accounting provisions of SFAS No.
123, compensation costs would have been determined based on the fair value of
the stock option

 (g) Share Rights Plan
 
  Rights to purchase Class A Ordinary Shares were distributed as a dividend at
the rate of one Right for each outstanding Class A Ordinary Share held of
record as of the close of business on October 31, 1998. Each Right will
entitle holders of XL Class A Ordinary Shares to buy one ordinary share at an
exercise price of $350.00. The Rights would be exercisable, and would detach
from the Class A Ordinary Shares, only if a person or group were to acquire 20
percent or more of XL's outstanding Class A Ordinary Shares, or were to
announce a tender or exchange offer that, if consumated, would result in a
person or group beneficially owning 20 percent or more of XL's Class A
Ordinary Shares. Upon a person or group without prior approval of the Board
acquiring 20 percent or more of XL's Class A Ordinary Shares, each Right would
entitle the holder (other than such an acquiring person or group) to purchase
XL Class A Ordinary Shares (or, in certain circumstances, Class A Ordinary
Shares of the acquiring person) with a value of twice the Rights exercise
price upon payment of the Rights exercise price. XL will be entitled to redeem
the Rights at $0.01 per Right at any time until the close of business on the
tenth day after the Rights become exercisable. The Rights will expire at the
close of business on September 30, 2008, and do not initially have a fair
value. The Company has initially reserved 119,073,878 Class A Ordinary Shares
being authorized and unissued for issuance upon exercise of the Rights.
 
11. Contributed Surplus
 
  Under the laws of the Cayman Islands, the use of XL's contributed surplus is
restricted to the issuance of fully paid shares (i.e., stock dividend or stock
split) and the payment of any premium on the redemption of ordinary shares.
 
12. Premiums

13. Reinsurance
 
  The Company is liable with respect to reinsurance ceded to the extent that
any reinsurance company fails to meet its obligation to the Company. The
Company regularly monitors the financial condition of its reinsurers and
believes there to be no material unrecoverable reinsurance.
 
14. Dividends
 
  In 1998, four regular quarterly dividends were paid, three of $0.40 per
share to shareholders of record at February 6, April 16 and July 15, and one
of $0.44 per share to shareholders of record at September 28.
 
  In 1997, four regular quarterly dividends were paid, three of $0.32 per

15. Taxation
 
  Under current Cayman Islands law, XL will not be obliged to pay any taxes in
the Cayman Islands on its income or gains until May 2006 pursuant to the
provisions of the Tax Concessions Law, as amended.
 
  Bermuda presently imposes no income, withholding or capital gains taxes, and
XL and its Bermuda subsidiaries are exempted until March 2016 from any such
future taxes pursuant to the Bermuda Exempted Undertakings Tax Protection Act
1966, and Amended Act 1987.
 
  X.L. Investments (Barbados), Inc. qualifies as an exempted company under the
provisions of the International Business Companies Act 1991-24 and as such is
subject to a maximum tax rate in Barbados of 2.50%.
 
  XLE has been approved to carry on business in the International Services
Centre in Dublin. Under Section 39 of the Finance Act 1990, XLE is entitled to
benefit from a 10% tax rate on profits (including investment income) until the
year 2005.
 
  Brockbank and XLMORe's London branch office are subject to United Kingdom
corporation taxes. Profits of XLMORe's Singapore branch office are subject to
Singapore corporation taxes. The German subsidiary of XLMORe is subject to
taxation in Germany.
 
  The Company's U.S. subsidiaries are subject to Federal, State and local
corporate income taxes and other taxes applicable to U.S. corporations.
 
  The Company has no material deferred taxes.
 
16. Statutory Financial Data
 
  The Company's ability to pay dividends is subject to certain regulatory
restrictions on the payment of dividends by its subsidiaries. The Company
relies primarily on cash dividends from XLI and XLMORe. The payment of such
dividends is restricted by applicable law including Bermuda, the United
States, the Republic of Ireland and United Kingdom insurance law and
regulations, and those promulgated by the Society of Lloyd's.
 
 Bermuda
 
  Under The Insurance Act, 1978, (as amended by the Insurance Act Amendment
1995) amendments thereto and related regulations of Bermuda (the "Act"), XLI
and XLMORe are required to prepare statutory financial statements and to file
in Bermuda a statutory financial return. The Act also requires these companies
to maintain certain measures of solvency and liquidity during the year. Other
subsidiaries of the Company based in Bermuda, including XLFA, LARe and Reeve
Court, are also subject to regulation under the Act.
 
  XLI's and XLMORe's statutory capital and surplus, statutory net income and
the minimum statutory capital and surplus required by the Act were as follows

  The primary difference between statutory net income and statutory capital
and surplus for the Company's subsidiaries as shown above, and net income and
shareholder's equity presented in accordance with generally accepted
accounting principles are deferred acquisition costs.
 
  Under the Act, XLI and XLMORe are classified as a Class 4 insurer and
reinsurer, respectively. Therefore they are restricted to the payment of
dividends in any one financial year of 25% of the prior year's statutory
capital and surplus, unless their directors attest that such dividends will
not cause the company to fail to meet its relevant margins. XLI and XLMORe
have not been affected by this. XLI could legally have paid dividends in the
amount of approximately $1.8 billion, $1.5 billion and $1.1 billion at
November 30, 1998, 1997 and 1996, respectively. XLMORe could legally have paid
dividends in the amount of approximately $1.3 billion, $403.4 million and
$169.5 million at November 30, 1998, 1997 and 1996, respectively.
 
Republic of Ireland
 
  XLE is permitted to cover risks throughout the European Community (subject
to certain restrictions) pursuant to the "Third Directive" relating to non-
life insurances. Its operations, however, are largely restricted to the
Republic of Ireland and are subject to regulation under Irish regulatory
authority. The principal legislation and regulations governing the insurance
activities of Irish insurance companies are the Companies Act of 1963 to 1990
and a range of Irish Insurance Acts from 1909 through 1995 (the "Irish Acts").
In addition, there is a comprehensive network of regulations and statutory
provisions empowering the making of regulations of which the most relevant are
the European Communities (Non-Life Insurance) Framework Regulations, 1994, the
European Communities (Insurance Undertakings Accounts) Regulations, 1996 and a
range of other European Communities Regulations and administrative rules (the
"Irish Regulations").
 
  XLE's insurance activities are subject to extensive regulation in the
Republic of Ireland, principally under the Irish Acts and Irish Regulations,
which impose on insurers headquartered in the Republic of Ireland minimum
solvency and reserve standards and auditing and reporting requirements and
grant to the Minister for Enterprise, Trade and Employment (the "Irish
Minister") wide powers to supervise, investigate and intervene in the affairs
of such insurers. The Irish Minister's powers and functions are exercised
through the Department of Enterprise, Trade and Employment.
 
 United States
 
  The Company's U.S. insurance subsidiaries are subject to regulatory
oversight under the insurance statutes and regulations of the jurisdictions in
which they conduct business. Brockbank, via Lloyd's, is a licensed insurer in
the states of Illinois, Kentucky and the U.S. Virgin Islands ("USVI"). It is
also an eligible surplus lines writer in all states other than Kentucky and
USVI, and an accredited reinsurer in every state other than Michigan.
Brockbank Insurance Services, Inc., is a California licensed surplus and
special lines broker.
 
  The insurance laws of each state of the United States and of many foreign
countries regulate the sale of insurance within their jurisdictions by alien
insurers, such as XLI and XLMORe. The Company believes it is not in violation
of the insurance laws of any state in the U.S. or any foreign country. From
time to time, various proposals for federal legislation within the United
States have been circulated which could require the Company to, among other
things, register as a surplus lines insurer. The Company believes that
generally it could meet and comply with the requirements to be registered as a
surplus lines insurer and such compliance would not
have a material impact on the ability of the Company to conduct its business.
There can be no assurance, however, that the activities of the Company will
not be challenged in the future or that the Company will be able to
successfully defend against such challenges or that legislation will not be
enacted that will affect the Company's ability to conduct its business.

 United Kingdom
 
  The United Kingdom Financial Services Authority ("UK FSA") regulates
reinsurance entities that are "effecting and carrying on" insurance business
in the United Kingdom. XLMORe, through its London branch, "effects and carries
on" business in the United Kingdom and is therefore regulated by the UK FSA.
 
 Lloyd's
 
  As a result of the Company's ownership of Brockbank, the Company and
Brockbank are subject to the regulatory jurisdiction of the Council of Lloyd's
(the "Council"). Unlike other financial markets in the UK, Lloyd's is not
subject to direct UK government regulation through The Financial Services Act
of 1986 but, instead, is self regulating by virtue of The Lloyd's Act of 1982
through bye-laws, regulations and codes of conduct written 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 and capital providers. Under the regulations, the
approval of the Council has to be obtained before any person can be a "major
shareholder" or "controller" of a corporate Name or a managing agency. The
Company has been approved as both a "major shareholder" and a "controller" of
its corporate Names (the "CCVs") and managing agencies.
 
  A person would be viewed by Lloyd's as a "major shareholder" of the CCVs if
such person owns 15% or more of the Company's outstanding capital stock and as
a "controller" if it owns 30% or more of the Company's outstanding capital
stock. Therefore, any person that becomes the owner of 15% 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.
 
  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 relevant managing agency, but there are no
provisions in The Lloyd's Act of 1982, the bye-laws or the regulations which
provide for any liabilities of the CCVs or the Brockbank group as a whole 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. The CCVs, as corporate members of
Lloyd's, are each required to commit a specified amount approximately equal to
50% of their underwriting capacity on the syndicates to support its
underwriting on those syndicates.
 
  The Lloyd's Act of 1982 generally restricts certain direct or indirect
equity cross-ownership between a Lloyd's broker and a Lloyd's managing agent.
 
 Other Regulation
 
  The Company is subject to regulation in Australia, Singapore and Germany as
a result of its representative offices and branches in such jurisdictions.

18. Accounting Standards
 
  The Financial Accounting Standards Board ("FASB") issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information",
effective for fiscal years beginning after December 15, 1997. This statement
established standards for reporting information about operating segments in
annual financial statements and requires selected information about operating
segments in interim financial reports issued to shareholders. It also
established standards for related disclosures about products and services,
geographical areas and major customers. Under SFAS No. 131, operating segments
are to be determined consistent with the way that management organizes and
evaluates financial information internally for making operating decisions and
assessing performance. The Company has not yet assessed the affect of the
adoption of this accounting standard on its consolidated financial statement
disclosures.
 
  FASB issued SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits", effective for fiscal years beginning after December
15, 1997. This Statement revises employers' disclosures about pensions and
other postretirement benefit plans. This standard is expected to have a
minimal impact on the Company's consolidated financial disclosures.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Concluded)
 
 
  FASB also issued SFAS No. 133, "Accounting for Derivative Instruments and
Hedging Activities", effective for all fiscal quarters of fiscal years
beginning after June 15, 1999. This Statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. If certain conditions
are met, a derivative may be specifically designated as a hedge. The
accounting for changes in fair value of a derivative (that is, gains and
losses) depends on the intended use of the derivative and the resulting
designation. The Company has not yet assessed the affect of the adoption of
this accounting standard on its consolidated financial statement disclosures.
 
  SFAS No. 131 and No. 133 are not expected to have a significant impact on
the Company's overall results but will affect the Company's financial
statements and disclosures.
 
19. Unaudited Subsequent Events
 
  On December 2, 1998, the Company announced that it has signed a definitive
agreement to acquire all of the outstanding shares of Intercargo Corporation
("Intercargo") for $12 per share, or approximately $88 million. Intercargo,
through its subsidiaries, underwrites specialty insurance products for
companies engaged in international trade, including U.S. customs bonds and
marine cargo insurance. At September 30, 1998, Intercargo had total assets of
$165 million and shareholders' equity of $81 million. The transaction is
subject to approval by Intercargo's shareholders, regulatory approvals and
other customary closing conditions. There can be no assurance that the
transaction will be completed or that the terms of the transaction will not be
modified prior to completion.
 
  On February 16, 1999 the Company announced that it had signed a definitive
merger agreement with NAC Re Corporation ("NAC Re"). Under the terms of the
agreement, shareholders of NAC Re will receive 0.915 Class A XL shares for
each NAC Re share in a tax-free exchange of shares that will be accounted for
as a pooling of interests under U.S. generally accepted accounting principles
("GAAP"). The transaction is subject to the approval of the NAC Re
stockholders, expiration of the applicable waiting period under the Hart-
Scott-Rodino Antitrust Improvements Act, receipt of insurance, regulatory
approvals and other customary closing conditions. There can be no assurance
that the transaction will be completed or that the terms of the transaction
will not be modified prior to completion.

  On March 16, 1998, the combination of EXEL and Mid Ocean was announced. The
shareholders of the two companies approved the two schemes of arrangement on
August 3, 1998 and the Grand Court of Cayman approved the arrangements on
August 7, 1998. The Company is the holding company for the new organization,
and the reinsurance operations of both companies were combined on August 7,
1998. The transaction, detailed in the joint proxy statement filed with the

EXEL and its subsidiaries), subject to the cash election rights of the two
companies' shareholders described therein. Prior to this transaction, EXEL
owned approximately 25% of Mid Ocean Class A shares.

                             FINANCIAL INFORMATION
 
1. Accounting for the Arrangements
 
  (a) The combination of EXEL and Mid Ocean was accounted for under purchase
accounting rules, in accordance with generally accepted accounting practice,
whereby the total purchase cost is allocated to the assets and liabilities
acquired based on their relative values at the date of acquisition, and the
excess of that total purchase cost over the fair values is recorded as
goodwill. The fair values ascribed to the individual assets and liabilities
are based upon management studies and appraisals.
 
  (b) Included in the pro forma income statements for the year ended November
30, 1998 and 1997 is the financial information of Mid Ocean for the nine
months ended July 31, 1998 and the year ended October 31, 1997, respectively.
No adjustments have been made to take account of these differing period ends
as, in the opinion of management, any such adjustments would not be material.
 
2. Allocation of Purchase Price Consideration:
 
  The allocation of the purchase price is as follows (U.S. dollars in
thousands):

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and
Shareholders of XL Capital Ltd:
 
  In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, of shareholders' equity and comprehensive
income and of cash flows present fairly, in all material respects, the
financial position of XL Capital Ltd and its subsidiaries at November 30, 1998
and 1997, and the results of their operations and their cash flows for each of
the three years in the period ended November 30, 1998, in conformity with
accounting principles generally accepted in the United States of America.
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 of these statements in accordance
with auditing standards generally accepted in the United States of America
which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.

amended, effective as of December 1, 1998, as follows:

          1.   Section 1 of the Plan is hereby amended by deleting "non-

          2.   Section 2(d) of the Plan is hereby amended to read as follows:

          "'Director' means a non-employee member of the Board and any other
     member of the Board who is designated by the Board as eligible to
     participate in this Plan."

          3.   Section 6(d) of the Plan is hereby amended to read as follows:


          "(d) (A)  In the case of units credited to a Director's account prior
     to December 1, 1998, if any dividends are payable on Shares during the
     deferral period, dividend equivalents equal to the dividend that would have
     been payable on the units credited to a Director's account if such units
     had constituted Shares shall be paid to the Director in cash at the time
     the corresponding dividends are paid on Shares.

               (B)  In the case of units credited to a Director's account after
     December 1, 1998, as of each date on which a cash dividend is paid on
     Shares, there shall be credited to each account that number of units
     (including fractional units) determined by
<PAGE>
 
                                      -2-



     (i) multiplying the amount of such dividend (per Share) by the number of
     units in such account; and (ii) dividing the total so determined by the
     Fair Market Value of a Share on the date of payment of such cash dividend.
     The additions to a Director's account pursuant to this Section 6(d)(B)
     shall continue until the Director's account is fully paid."

          4.   Section 6(e) of the Plan is hereby amended to read as follows:

          "(e) (A)  In the case of units credited to a Director's account prior
     to December 1, 1998, the amount to which a Director is entitled hereunder
     that is represented by Share units shall be distributed to the Director,
     whether or not the Director's service continues, in the form of one Share
     for each Share unit in accordance with the following schedule:


     Percentage
     of Unit                              Time of Distribution
     -------                              --------------------

       20                      1st anniversary of Date Unit Credited
       20                      2nd anniversary of Date Unit Credited
       20                      3rd anniversary of Date Unit Credited
       20                      4th anniversary of Date Unit Credited
       20                      5th anniversary of Date Unit Credited


               (B)  In the case of units credited to a Director's account after
     December 1, 1998, the account of a Director shall be distributed (in the
     form of one Share for each Share unit) either (x) in a lump sum at the time
     of termination of the Director's service on the Board or (y) in up to five
     annual installments commencing at the time of termination of the director's
     service on the Board, as elected by the Director. Each Director's
     distribution election must be made in writing within the later of (A) 60
     days after December 1, 1998 or (B) 60 days after the Director first becomes
     eligible to participate in the Plan; provided, however, that a Director may
                                          --------  -------
     made a new distribution election with respect to the entire portion of his
     or her account subject to this Section 6(e)(B) so long as such election is
     made at least one year in advance of the Director's termina-
<PAGE>
 
                                      -3-

     tion of service on the Board. In the case of an account distributed in
     installments, the amount of Shares distributed in each installment shall be
     equal to the number of Share units in the Director's account subject to
     such installment distribution at the time of the distribution divided by
     the number of installments remaining to be paid."

          5.   The following paragraph (g) is hereby added to Section 6 of the
Plan.

          "(g) Each Director may make an election in writing on or prior to each
     October 31 to receive the Director's annual retainer fees payable in the
     following Fiscal Year in the form of Shares instead of cash. Any Shares
     elected shall be payable at the time cash retainer fees are otherwise
     payable, and the number of Shares distributed shall be equal to the amount
     of the annual retainer fee otherwise payable on such payment date divided
     by the Fair Market Value of a Share on such date. Notwithstanding the
     foregoing, a Director who is first elected or appointed to the Board may
     make an election under this Section 6(g) within 60 days of such election or
     appointment in respect of annual retainer fees payable after the date of
     the election. Any election made under this Section 6(g) shall remain in
     effect unless and until a new election is made in accordance with the
     provisions of this Section 6(g)."

          6.   The following paragraph (h) is hereby added to Section 6 of the
Plan.

          "(h) Adjustments.  In the event that any dividend in Shares,
               -----------                                            
     recapitalization, Share split, reverse split, reorganization, merger,
     consolidation, spin-off, combination, repurchase, or share exchange, or
     other such change, affects the Shares such that they are increased or
     decreased or changed into or exchanged for a different number or kind of
     Shares, other securities of the Company or of another corporation or other
     consideration, then in order to maintain the proportionate interest of the
     Directors and preserve the value of the Directors' Share units,
<PAGE>
 
                                      -4-

     there shall automatically be substituted for each Share unit a new unit
     representing the number and kind of Shares, other securities or other
     consideration into which each outstanding Share shall be changed. The
     substituted units shall be subject to the same terms and conditions as the
     original Share units."

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

          (a)  Authority of the Committee.  Except as provided in Section 7, 
               --------------------------      
   the Plan shall be administered by the Committee, and the Committee shall have
   full and final authority to take the following actions, in each case subject
   to and consistent with the provisions of the Plan:

                    (i)    to select Eligible Employees to whom Awards may be

<PAGE>
 
                                      -8-

          (iv) to determine the type and number of Awards to be granted, the
      number of Shares to which an Award may relate, the terms and conditions of
      any Award granted under the Plan (including, but not limited to, any
      exercise price, grant price, or purchase price, and any bases for
      adjusting such exercise, grant or purchase price, any restriction or
      condition, any schedule for lapse of restrictions or conditions relating

      Award, and waiver or accelerations thereof, and waivers of performance

          (v)  to determine whether, to what extent, and under what

<PAGE>
 
                                      -9-

          (vi)    to determine whether, to what extent, and under what
      circumstances cash, Shares, other Awards, or other property payable with
      respect to an Award will be deferred either automatically, at the election
      of the Committee, or at the election of the Eligible Employee;

          (vii)   to prescribe the form of each Award Agreement, which need not
      be identical for each Eligible Employee;

          (viii)  to adopt, amend, suspend, waive, and rescind such rules and
      regulations and appoint such agents as the Committee may deem necessary or
      advisable to administer the Plan;

          (ix)    to correct any defect or supply any omission or reconcile any

          sary or advisable for the administration of the Plan.

          (b) Manner of Exercise of Committee Authority. The Committee shall
              -----------------------------------------

   binding on all persons, including the Company, Subsidiaries, Affiliates,
   Eligible Employees, any person claiming any rights under the Plan from or
   through any Eligible Employee, and shareholders. The express grant of any
   specific power to the Committee, and the taking of any action by the
   Committee, shall not be construed as limiting any power or authority of the
   Committee. The Committee may delegate to officers or managers of the Company
   or any Subsidiary or Affiliate the authority, subject to such terms as the
   Committee shall determine, to perform administrative functions and, with
   respect to Awards granted to persons not subject to Section 16 of the
   Exchange Act, to perform such other functions as the Committee may determine,
   to the extent permitted under Rule 16b-3 (if applicable) and applicable law.

          (c) Limitation of Liability.  Each member of the Committee shall be
              -----------------------                                        
   entitled to, in good faith, rely or
<PAGE>
 
                                     -11-

   act upon any report or other information furnished to him or her by any
   officer or other employee of the Company or any Subsidiary or Affiliate, the
   Company's independent certified public accountants, or other professional
   retained by the Company to assist in the administration of the Plan. No
   member of the Committee, nor any officer or employee of the Company acting on
   behalf of the Committee, shall be personally liable for any action,
   determination, or interpretation taken or made in good faith with respect to
   the Plan, and all members of the Committee and any officer or employee of the
   Company acting on their behalf shall, to the extent permitted by law, be
   fully indemnified and protected by the Company with respect to any such
   action, determination, or interpretation.

          4.   Shares Subject to the Plan.
               -------------------------- 

          (a)  Subject to adjustment as hereinafter provided, the total number
   of Shares reserved for issuance in connection with Awards, Director's Options
   and Director's Replacement Options under the Plan shall be 2,250,000. No
   Award, Director's Option or Director's Replacement Option may be granted if
   the number of Shares to which such Award, Director's Option or Director's
   Replacement Option relates, when added to the
<PAGE>
 
                                     -12-

   number of Shares previously issued under the Plan, exceeds the number of
   Shares reserved under the preceding sentence. If any Shares subject to an
   Award, Director's Option or Director's Replacement Option are forfeited,
   cancelled, exchanged or surrendered or such Award, Director's Option or
   Director's Replacement Option is settled in cash or otherwise terminates
   without a distribution of Shares to the Participant, any Shares counted
   against the number of Shares reserved and available under the Plan with
   respect to such Award, Director's Option or Director's Replacement Option
   shall, to the extent of any such forfeiture, settlement, termination,
   cancellation, exchange or surrender, again be available for Awards,
   Director's Options or Director's Replacement Options under the Plan;
   provided, however, that in the case of forfeiture, cancellation, exchange or
   --------  -------
   surrender of Restricted Shares or Restricted Share Units with respect to
   which dividends or Dividend Equivalents have been paid or accrued, such
   number of Shares shall not be available for Awards, Director's Options or
   Director's Replacement Options unless, in the case of Shares with respect to
   which dividends or Dividend Equivalents were accrued but unpaid, such
   dividends and Dividend Equivalents are also forfeited, cancelled, exchanged
   or surrendered. Upon the
<PAGE>
 
                                     -13-

   exercise of any Award granted in tandem with any other Awards, such related
   Awards shall be cancelled to the extent of the number of Shares as to which
   the Award is exercised.

          (b)  Any Shares distributed pursuant to an Award, Director's Option or
   Director's Replacement Option may consist, in whole or in part, of authorized
   and unissued Shares or treasury Shares including Shares acquired by purchase
   in the open market or in private transactions.

          (c)  In the event that the Committee shall determine that any dividend
   in Shares, recapitalization, Share split, reverse split, reorganization,
   merger, consolidation, spin-off, combination, repurchase, or share exchange,
   or other similar corporate transaction or event, affects the Shares such that
   an adjustment is appropriate in order to prevent dilution or enlargement of
   the rights of Eligible Employees under the Plan, then the Committee shall
   make such equitable changes or adjustments as it deems appropriate and, in
   such manner as it may deem equitable, adjust any or all of (i) the number and
   kind of Shares which may thereafter be issued under the Plan, (ii) the number
   and kind of Shares issued or issuable in respect of outstanding Awards,
<PAGE>
 
                                     -14-

   and (iii) the exercise price, grant price, or purchase price relating to any
   Award; provided, however, in each case that, with respect to ISOs, such
          --------  ------- 
   adjustment shall be made in accordance with Section 424(h) of the Code,
   unless the Committee determines otherwise. In addition, the Committee is
   authorized to make adjustments in the terms and conditions of, and the
   criteria and performance objectives included in, Awards in recognition of
   unusual or non-recurring events (including, without limitation, events
   described in the preceding sentence) affecting the Company or any Subsidiary
   or Affiliate or the financial statements of the Company or any Subsidiary or
   Affiliate, or in response to changes in applicable laws, regulations, or
   accounting principles.

          (a)  General.  Awards may be granted on the terms and conditions set

   regarding forfeiture of Awards or continued exercis-

          the Committee may, without limitation, set an exercise price that is

      delivered or deemed to be delivered to Eligible Employees.

               (ii)  Other Terms.  The Committee shall determine, at the time

   Shares to Eligible Employees on the following terms and conditions:

          (i)  Issuance and Restrictions.  Restricted Shares shall be subject to
               -------------------------

      restrictions may lapse separately or in combination at such times, under
      such circumstances (including, without limitation, upon achievement of
      performance criteria if deemed appropriate by the Committee), in such
      installments, or otherwise, as the Committee may determine. Except to the

                                                       --------  -------
      the Committee may provide, by rule or regulation or in any Award
      Agreement, or may determine in any individual case, that restrictions or
      forfeiture conditions relating to Restricted Shares will be waived in
      whole or in part in the event of terminations resulting from specified

      forfeiture of Restricted Shares.

          (iii) Certificates for Shares.  Restricted Shares granted under the

      determined by the Committee, in cash or in unrestricted Shares having a
      Fair Market Value equal to the amount of such dividends. Shares
      distributed in connection with a Share split or dividend in Shares, and
      other property distributed as a dividend, shall be subject to restrictions

      restrictions as the Committee may impose, if any (including, without
      limitation, the achievement of performance criteria if deemed appropriate
      by the Committee), at the date of grant or thereafter, which restrictions
      may lapse at the expiration of the deferral period or at earlier or later
      specified times, separately or in combination, in installments or
      otherwise, as the Committee may determine.

          (ii) Forfeiture.  Except as otherwise determined by the Committee at
               ----------                                                     
      date of grant or thereafter, upon termination of employment (as determined
      under criteria established by the Committee) during the applicable
      deferral period or portion thereof to which forfeiture conditions apply
      (as provided in the Award Agreement evidencing the Restricted Share
      Units), or upon failure to satisfy any other conditions precedent to the
      delivery of Shares or cash to which such Restricted Share Units relate,
      all Restricted Share Units that are at 
<PAGE>
 
                                     -22-

      that time subject to deferral or restriction shall be forfeited; provided,
                                                                       --------
      however, that the Committee may provide, by rule or regulation or in any
      -------
      Award Agreement, or may determine in any individual case, that
      restrictions or forfeiture conditions relating to Restricted Share Units
      will be waived in whole or in part in the event of termination resulting
      from specified causes, and the Committee may in other cases waive in whole
      or in part the forfeiture of Restricted Share Units.

      (f) Performance Shares and Performance Units.  The Committee is authorized
          ----------------------------------------                              
   to grant Performance Shares or Performance Units or both to Eligible
   Employees on the following terms and conditions:

               (i)  Performance Period. The Committee shall determine a
                    ------------------
      performance period (the "Performance Period") of one or more years and
      shall determine the performance objectives for grants of Performance
      Shares and Performance Units. Performance objectives may vary from
      Eligible Employee to Eligible Employee and shall be based upon such
      performance criteria as the Committee may deem appropriate. Per-
<PAGE>
 
                                     -23-

      formance Periods may overlap and Eligible Employees may participate
      simultaneously with respect to Performance Shares and Performance Units
      for which different Performance Periods are prescribed.

          (ii)  Award Value.  At the beginning of a Performance Period, the
                -----------                                                
      Committee shall determine for each Eligible Employee or group of Eligible
      Employees with respect to that Performance Period the range of number of
      Shares, if any, in the case of Performance Shares, and the range of dollar
      values, if any, in the case of Performance Units, which may be fixed or
      may vary in accordance with such performance or other criteria specified
      by the Committee, which shall be paid to an Eligible Employee as an Award
      if the relevant measure of Company performance for the Performance Period
      is met.

          (iii) Significant Events.  If during the course of a Performance
                ------------------                                        
      Period there shall occur significant events as determined by the Committee
      which the Committee expects to have a substantial effect on a performance
      objective 
<PAGE>
 
                                     -24-

      during such period, the Committee may revise such objective.

          (iv) Forfeiture.  Except as otherwise determined by the Committee, at
               ----------                                                      
      the date of grant or thereafter, upon termination of employment during the
      applicable Performance Period, Performance Shares and Performance Units
      for which the Performance Period was prescribed shall be forfeited;
      provided, however, that the Committee may provide, by rule or regulation
      --------  -------                                                       
      or in any Award Agreement, or may determine in an individual case, that
      restrictions or forfeiture conditions relating to Performance Shares and
      Performance Units will be waived in whole or in part in the event of
      terminations resulting from specified causes, and the Committee may in
      other cases waive in whole or in part the forfeiture of Performance Shares
      and Performance Units.

          (v)  Payment.  Each Performance Share or Performance Unit may be paid
               -------                                                         
      in whole Shares, or cash, or a combination of Shares and cash either as a
      lump sum payment or in annual installments, all as the Committee shall
      deter-
<PAGE>
 
                                     -25-

      mine, at the time of grant of the Performance Share or Performance Unit or
      otherwise, commencing as soon as practicable after the end of the relevant
      Performance Period.

      (g) Dividend Equivalents. The Committee is authorized to grant Dividend
          --------------------                                               
   Equivalents to Eligible Employees.  The Committee may provide, at the date of
   grant or thereafter, that Dividend Equivalents shall be paid or distributed
   when accrued or shall be deemed to have been reinvested in additional Shares,
   or other investment vehicles as the Committee may specify, provided that
   Dividend Equivalents (other than freestanding Dividend Equivalents) shall be
   subject to all conditions and restrictions of the underlying Awards to which
   they relate.

      (h) Other Share-Based Awards.  The Committee is authorized, subject to
          ------------------------                                          
   limitations under applicable law, to grant to Eligible Employees such other
   Awards that may be denominated or payable in, valued in whole or in part by
   reference to, or otherwise based on, or related to, Shares, as deemed by the
   Committee to be consistent with the purposes of the Plan, including, without
   limitation, unrestricted shares awarded purely as a "bonus" and not subject
   to any restrictions or
<PAGE>
 
                                     -26-

   conditions, other rights convertible or exchangeable into Shares, purchase
   rights for Shares, Awards with value and payment contingent upon performance
   of the Company or any other factors designated by the Committee, and Awards
   valued by reference to the performance of specified Subsidiaries or
   Affiliates. The Committee shall determine the terms and conditions of such
   Awards at date of grant or thereafter. Shares delivered pursuant to an Award
   in the nature of a purchase right granted under this Section 5(h) shall be
   purchased for such consideration, paid for at such times, by such methods,
   and in such forms, including, without limitation, cash, Shares, notes or
   other property, as the Committee shall determine. Cash awards, as an element
   of or supplement to any other Award under the Plan, shall also be authorized
   pursuant to this Section 5(h).

          6.   Certain Provisions Applicable to Awards.
               --------------------------------------- 

          (a)  Stand-Alone, Additional, Tandem and Substitute Awards. Awards
               -----------------------------------------------------
   granted under the Plan may, in the discretion of the Committee, be granted to
   Eligible Employees either alone or in addition to, in tandem with, or in
   exchange or substitution for, any other Award granted under the Plan or any
   award granted under any other plan or agreement of the Company, any
   Subsidiary
<PAGE>
 
                                     -27-

   or Affiliate, or any business entity to be acquired by the Company or a
   Subsidiary or Affiliate, or any other right of an Eligible Employee to
   receive payment from the Company or any Subsidiary or Affiliate. Awards may
   be granted in addition to or in tandem with such other Awards or awards, and
   may be granted either as of the same time as or a different time from the
   grant of such other Awards or awards. The per Share exercise price of any
   Option, grant price of any SAR, or purchase price of any other Award
   conferring a right to purchase Shares which is granted, in connection with
   the substitution of awards granted under any other plan or agreement of the
   Company or any Subsidiary or Affiliate or any business entity to be acquired
   by the Company or any Subsidiary or Affiliate, shall be determined by the
   Committee, in its discretion.

          (b)  Terms of Awards.  The term of each Award granted to an Eligible
               ---------------                                                
   Employee shall be for such period as may be determined by the Committee;
   provided, however, that in no event shall the term of any ISO or an SAR
   --------  -------                                                      
   granted in tandem therewith exceed a period of ten years from the date of its
   grant (or such shorter period as may be applicable under Section 422 of the
   Code).
<PAGE>
 
                                     -28-

          (c)  Form of Payment Under Awards. Subject to the terms of the Plan
               ---------------------------- 
   and any applicable Award Agreement, payments to be made by the Company or a
   Subsidiary or Affiliate upon the grant, maturation, or exercise of an Award
   may be made in such forms as the Committee shall determine at the date of
   grant or thereafter, including, without limitation, cash, Shares, or other
   property, and may be made in a single payment or transfer, in installments,
   or on a deferred basis. The Committee may make rules relating to installment
   or deferred payments with respect to Awards, including the rate of interest
   to be credited with respect to such payments.

          (d)  Nontransferability. Awards shall not be transferable by an
               ------------------
   Eligible Employee except by will or the laws of descent and distribution
   (except pursuant to a Beneficiary) and shall be exercisable during the
   lifetime of an Eligible Employee only by such Eligible Employee or his
   guardian or legal representative. An Eligible Employee's rights under the
   Plan may not be pledged, mortgaged, hypothecated, or otherwise encumbered,
   and shall not be subject to claims of the Eligible Employees creditors.

          7.   Director's Options
               ------------------

          (a)  Annual Grant. On the date of each annual meeting of the Company's
               ------------ 
   shareholders, beginning with the 1994 annual meeting, each Director in office
   immediately following the meeting shall automatically be granted a NQSO to
   purchase 1,500 Shares with an exercise price equal to 100 percent of the
   Market Value of one Share at the date of grant; provided, however, that such
                                                   --------  -------           
   price shall be at least equal to the par value of a Share.  For purposes of
   Section 7, Market Value shall mean the mean between the high and low selling
   prices per Share on the immediately preceding date (or, if the Shares were
   not traded on that day, the next preceding day that the Shares were traded).

          (b)  Exercisability. Each Option granted to a Director under paragraph
               --------------
   (a) hereof shall become fully exercisable on the date which is six months
   after the date of grant, and shall expire on the tenth anniversary of the
   date of grant. Exercisability of a Director's Option shall not be dependent
   upon the Director's continuing service on the Board.

          (c)  Time and Method of Exercise. The exercise price of a Director's
               ---------------------------
   Option shall be paid to the Com-
<PAGE>
 
                                     -30-

   pany at the time of exercise either in cash, or in Shares already owned by
   the optionee and having a total Market Value equal to the exercise price, or
   in a combination of cash and such Shares.

          (d)  Nontransferability. No Director's Option granted under the Plan
               ------------------
   shall be transferable other than by will or by the laws of descent and
   distribution. During the lifetime of the optionee, a Director's Option shall
   be exercisable only by him or her or by his or her guardian or legal
   representative.

          (e)  Adjustments. In the event that subsequent to the Effective Date
               -----------
   any dividend in Shares, recapitalization, Share split, reverse split,
   reorganization, merger, consolidation, spin-off, combination, repurchase, or
   share exchange, or other such change, affects the Shares such that they are
   increased or decreased or changed into or exchanged for a different number or
   kind of shares or other securities of the Company or of another corporation,
   then in order to maintain the proportionate interest of the Director and
   preserve the value of the Director's Option, (i) there shall automatically be
   substituted for each Share subject to an unexercised Director's Option and
   each Share to be issued under Section 7(a) subsequent to such event the
<PAGE>
 
                                     -31-

   number and kind of shares or other securities into which each outstanding
   Share shall be changed or for which each such Share shall be exchanged, and
   (ii) the exercise price shall be increased or decreased proportionately so
   that the aggregate purchase price for the Shares subject to any unexercised
   Director's Option shall remain the same as immediately prior to such event.

          (f)  Administration. To the extent the Plan relates to Director's
               --------------
   Options or Director's Replacement Options, it is intended to operate
   automatically and not require administration. However, to the extent that
   administration is necessary with respect to such grants, the Plan shall be
   administered by the Secretary of the Company. Since the Director's Options
   and Director's Replacement Options are awarded automatically, this function
   will be limited to ministerial matters. The plan administrator will have no
   discretion with respect to the selection of Director optionees, the
   determination of the exercise price of Director's Options or Director's
   Replacement Options, the timing of such grants or number of Shares covered by
   the Director's Options or Director's Replacement Options.

          8.   Director's Replacement Options.
               ------------------------------ 

          On the closing date of the exchange of shares of Mid Ocean Reinsurance
Company Ltd. ("Mid Ocean Reinsurance") for Shares, each Director shall be
granted a Director's Replacement Option (with a tandem stock appreciation right)
to purchase 1,500 Shares at a price equal to U.S. $16.67 per Share in
replacement of his existing option (and tandem stock appreciation right) to
purchase common stock of Mid Ocean Reinsurance (such existing option and tandem
stock appreciation right is referred to herein as a "Mid Ocean Reinsurance
Option"). Such a Director's Replacement Option (and tandem stock appreciation
right) shall be exercisable immediately at the time of grant, shall expire on
November 4, 2002, and shall otherwise have substantially the same terms as the
Mid Ocean Reinsurance Option it replaces, except that the exercise price of the
Director's Replacement option shall not be adjusted as a result of dividends
(other than dividends paid in Shares).

          9.   General Provisions.
               ------------------ 

          (a)  Compliance with Legal and Trading Requirements. The Plan, the
               ----------------------------------------------
   granting and exercising of Awards, Director's Options and Director's
   Replacement Options thereunder, and the other obligations of the Company
   under the Plan and any Award Agreement, shall
<PAGE>
 
                                     -33-

   be subject to all applicable Cayman Islands and U.S. federal and state laws,
   rules and regulations and to such approvals by any regulatory or governmental
   agency as may be required. The Company, in its discretion, may postpone the
   issuance or delivery of Shares under any Award, Director's Option or
   Director's Replacement Option until completion of such stock exchange or
   market system listing or registration or qualification of such Shares or
   other required action under any Cayman Islands or U.S. state or federal law,
   rule or regulation as the Company may consider appropriate, and may require
   any Participant to make such representations and furnish such information as
   it may consider appropriate in connection with the issuance or delivery of
   Shares in compliance with applicable laws, rules and regulations. No
   provisions of the Plan shall be interpreted or construed to obligate the
   Company to register any Shares under Cayman Islands or U.S. federal or state
   law.

          (b)  No Right to Continued Employment or Service. Neither the Plan nor
               -------------------------------------------
   any action taken thereunder shall be construed as giving any employee or
   director the right to be retained in the employ or service of the Company or
   any of its Subsidiaries or Affiliates, nor
<PAGE>
 
                                     -34-

   shall it interfere in any way with the right of the Company or any of its
   Subsidiaries or Affiliates to terminate any employee's or director's
   employment or service at any time.

          (c)  Taxes. The Company or any Subsidiary or Affiliate is authorized
               -----
   to withhold from any Award granted, any payment relating to an Award under
   the Plan, including from a distribution of Shares, or any payroll or other
   payment to an Eligible Employee, amounts of withholding and other taxes due
   in connection with any transaction involving an Award, and to take such other
   action as the Committee may deem advisable to enable the Company and Eligible
   Employees to satisfy obligations for the payment of withholding taxes and
   other tax obligations relating to any Award. This authority shall include
   authority to withhold or receive Shares or other property and to make cash
   payments in respect thereof in satisfaction of an Eligible Employee's tax
   obligations.

          (d)  Changes to the Plan and Awards. The Board may amend, alter,
               ------------------------------
   suspend, discontinue, or terminate the Plan or the Committee's authority to
   grant Awards under the Plan without the consent of shareholders of the
   Company or Participants, except that any such
<PAGE>
 
                                     -35-

   amendment, alteration, suspension, discontinuation, or termination shall be
   subject to the approval of the Company's shareholders within one year after
   such Board action if such shareholder approval is required by any Cayman
   Islands or U.S. federal law or regulation (including Rule 16b-3, if
   applicable) or the rules of any stock exchange or automated quotation system
   on which the Shares may then be listed or quoted; provided, however, that,
                                                     --------  -------
   without the consent of an affected Participant, no amendment, alteration,
   suspension, discontinuation, or termination of the Plan may impair the rights
   or, in any other manner, adversely affect the rights of such Participant
   under any Award, Director's Option or Director's Replacement Option
   theretofore granted to him or her. The Committee may waive any conditions or
   rights under, or amend, alter, suspend, discontinue, or terminate any Award
   theretofore granted any Award Agreement relating thereto; provided, however,
                                                             --------  -------
   that, without the consent of an affected Eligible Employee, no such
   amendment, alteration, suspension, discontinuation, or termination of any
   Award may impair or adversely affect the rights of such Eligible Employee
   under such Award. Notwithstanding the other provisions of this paragraph,
   Section 7, Section 8 and the other provisions of this Plan applicable to
   Direc-
<PAGE>
 
                                     -36-

   tor's Options or Director's Replacement Options may not be amended more than
   once every six months other than to comport with changes in the Code, the
   Employee Retirement Income Security Act of 1974, as amended, or the rules
   thereunder.

          (e)  No Rights to Awards; No Shareholder Rights. No Eligible Employee
               ------------------------------------------ 
   or employee shall have any claim to be granted any Award under the Plan, and
   there is no obligation for uniformity of treatment of Eligible Employees and
   employees. No Award shall confer on any Eligible Employee any of the rights
   of a shareholder of the Company unless and until Shares are duly issued or
   transferred to the Eligible Employee in accordance with the terms of the
   Award.

          (f)  Unfunded Status of Awards.  The Plan is intended to constitute an
               -------------------------                                        
   "unfunded" plan for incentive compensation.  With respect to any payments not
   yet made to a Participant pursuant to an Award, Director's Option or
   Director's Replacement Option, nothing contained in the Plan or any Award,
   Director's Option or Director's Replacement Option shall give any such
   Participant any rights that are greater than those of a general creditor of
   the Company; provided, however, that the Committee may authorize the creation
                --------  -------                                               
   of trusts 
<PAGE>
 
                                     -37-

   or make other arrangements to meet the Company's obligations under the Plan
   to deliver cash, Shares, other Awards, or other property pursuant to any
   Award, which trusts or other arrangements shall be consistent with the
   "unfunded" status of the Plan unless the Committee otherwise determines with
   the consent of each affected Participant.

          (g)  Nonexclusivity of the Plan. Neither the adoption of the Plan by
               --------------------------
   the Board nor its submission to the shareholders of the Company for approval
   shall be construed as creating any limitations on the power of the Board to
   adopt such other incentive arrangements as it may deem desirable, including,
   without limitation, the granting of options and other awards otherwise than
   under the Plan, and such arrangements may be either applicable generally or
   only in specific cases.

          (h)  Not Compensation for Benefit Plans. No Award payable under this
               ----------------------------------
   Plan shall be deemed salary or compensation for the purpose of computing
   benefits under any benefit plan or other arrangement of the Company for the
   benefit of its employees or directors unless the Company shall determine
   otherwise.
<PAGE>
 
                                     -38-

          (i)  No Fractional Shares.  No fractional Shares shall be issued or
               --------------------                                          
   delivered pursuant to the Plan or any Award or Director's Option. In the case
   of Awards to Eligible Employees, the Committee shall determine whether cash,
   other Awards, or other property shall be issued or paid in lieu of such
   fractional Shares or whether such fractional Shares or any rights thereto
   shall be forfeited or otherwise eliminated. In the case of Director's
   Options, cash shall be paid in lieu of such fractional shares.

          (j)  Governing Law. The validity, construction, and effect of the
               -------------
   Plan, any rules and regulations relating to the Plan, and any Award Agreement
   shall be determined in accordance with the laws of New York without giving
   effect to principles of conflict of laws.

          (k)  Effective Date; Plan Termination. The Plan shall become effective
               --------------------------------
   as of _______________________, (the "Effective Date") upon approval by the
   affirmative votes of the holders of a majority of voting securities of the
   Company. The Plan shall terminate as to future awards on the date which is
   ten (10) years after the Effective Date, or, if earlier, at such time as no

                               MID OCEAN LIMITED
                       STOCK & DEFERRED COMPENSATION PLAN
                           FOR NONEMPLOYEE DIRECTORS

          SECTION 1.    Introduction.
                        ------------ 

          The Mid Ocean Limited Stock & Deferred Compensation Plan for
Nonemployee Directors (the "Plan") provides an opportunity for nonemployee
directors of Mid Ocean Limited to defer their annual retainer fees and have them
deemed invested in Shares.  It also provides for the payment of annual retainer
fees of Directors in the form of Shares.  The Plan is intended to encourage
qualified individuals to accept nominations as directors of Mid Ocean Limited
and to strengthen the mutuality of interest between the nonemployee directors
and Mid Ocean Limited's other shareholders.

          SECTION 2.    Definitions.
                        ----------- 
          For purposes of the Plan, the following terms shall be defined as set
forth below.

          (a)  "Board" means the Board of Directors of the Company.

          (b)  "Code" means the Internal Revenue Code of 1986, as amended from
time to time. References to any provision of the Code shall be deemed to include
successor provisions thereto and regulations thereunder.

          (c)  "Company" means Mid Ocean Limited, a corporation organized under
the laws of the Cayman Islands, or any successor corporation.

          (d)  "Director" means a member of the Board who is not employed by the
Company or any of its subsidiaries.

          (e)  "Fair Market Value" means, with respect to Shares on any day, the
following:

               (i)  if the Shares are at the time listed or admitted to trading
     on any stock exchange, then the Fair Market Value shall be the closing
     selling price per share of Shares on the day preceding the date in question
     on the stock exchange which is the primary market for the Shares, as such
     is officially quoted on such exchange, and if there is no reported sale of
     Shares on such exchange on such date, then the Fair Market Value shall be
     the closing 
<PAGE>
 
                                      -2-


     selling price on the exchange on the last preceding date for which such
     quotation exists; and

               (ii) if the Shares are not at the time listed or admitted to
     trading on any stock exchange but are traded in the over-the-counter
     market, the Fair Market Value shall be the closing selling price per share
     of Shares on the day preceding the date in question, as such price is
     reported by the National Association of Securities Dealers through the
     NASDAQ National Market System or any successor system, and if there is no
     reported closing selling price for Shares on such date, then the closing
     selling price on the last preceding date for which such quotation exists
     shall be determinative of Fair Market Value.

          (f)  "Plan" means this Stock & Deferred Compensation Plan for
Nonemployee Directors.

          (g)  "Plan Benefits" means the benefits described in Sections 5 and 6
hereof.

          (h)  "Plan Year" means the calendar year.

          (i)  "Shares" means Class A Ordinary Shares, $0.20 par value per
share, of the Company.

          SECTION 3.    Administration.
                        -------------- 

          The Plan shall be administered by the Board.  The Board shall have
full authority to construe and interpret the Plan, and any action of the Board
with respect to the Plan shall be final, conclusive, and binding on all persons.

           SECTION 4.    Annual Retainer Paid In Shares.
                         ------------------------------ 

          After the Effective Date of this Plan, each Director's annual retainer
fee shall, subject to any deferral election made pursuant to Section 5 below, be
paid in the form of Shares on a quarterly basis, in arrears.  The number of
Shares paid on each quarterly payment date shall be the number of Shares having
an aggregate Fair Market Value (on the payment date) equal to one fourth of the
Director's annual retainer fee.  Fractional Share certificates will not be
issued, and cash will be paid in lieu of fractional Shares at the time of

          SECTION 5.    Share Unit Accounts.
                        ------------------- 
          The Company shall maintain a Share unit account (an "Account") for
each Director. Share units will be credited to each such Account as follows:

          (a) Each Director may make an irrevocable election on or before the
December 31 immediately preceding the beginning of a Plan Year by written notice
to the Company, to defer payment of all of the compensation otherwise payable as
his or her annual retainer fee for service as a Director for the Plan Year.
Notwithstanding the foregoing, a Director may make such an election within 70
days after first becoming eligible to participate in the Plan, with respect to
compensation payable after the effective date of the election. All compensation
which a Director elects to defer pursuant to this Section 5(a) shall be credited
in the form of Share units to the Director's Account. The number of units
(including fractional units) so credited will be equal to the number of Shares
(including fractional Shares) having an aggregate Fair Market Value (on the date
the compensation would otherwise have been paid) equal to the amount by which
the Director's compensation was reduced pursuant to the deferral election.
Deferrals of compensation hereunder shall continue until the Director notifies
the Company in writing, on or prior to the December 31 immediately preceding the
commencement of any Plan Year, that the Director wishes his or her compensation
for such Plan Year and succeeding periods to be paid on a current basis.

                   
          (b)  As of each date on which a cash dividend is paid on Shares, there
shall be credited to each Account that number of Share units (including
fractional units) determined by (i) multiplying the amount of such dividend (per
share) by the number of Share units in such Account; and (ii) dividing the total
so determined by the Fair Market Value of a Share on the date of payment of such
cash dividend. The additions to a Director's Account pursuant to this Section
5(b) shall continue until the Director's Plan Benefit is fully paid.
<PAGE>
 
                                      -4-

          SECTION 6. Plan Benefits.
                     ------------- 

          (a)  Form.  The Plan Benefit of a Director shall consist of Shares 
               ----
equal in number to the Share units in the Director's Account. Any fractional
Share unit shall be paid in cash.

           (b)  Distribution.
                ------------ 

                (i)  The Plan Benefit of a Director shall be distributed in a
     lump sum at the time of termination of the Director's service on the Board.

                 (ii) In the case of the death of a Director, the Director's
     Plan Benefit shall be distributed, within a reasonable time as determined
     by the Company, after the Director's death to the Director's beneficiary or
     beneficiaries, as specified by the Director on a form furnished by and
     filed with the Secretary of the Company. If no beneficiary has been
     designated by the Director or if no beneficiary survives the Director, the
     undistributed balance of his or her Plan Benefit shall be distributed to
     the Director's surviving spouse as beneficiary if such spouse is still
     living or, if not living, in equal shares to the then living children of
     the Director as beneficiaries or, if none, to the Director's estate as
     beneficiary.

          SECTION 7.    General.
                        ------- 
          (a)  Nontransferability.  Except as provided in Section 6(b)(ii), no
               ------------------
payment of any Plan Benefit of a Director shall be anticipated, assigned,
attached, garnished, optioned, transferred or made subject to any creditor's
process, whether voluntarily or involuntarily or by operation of law. Any act in
violation of this subsection shall be void.

          (b)  Compliance with Legal and Trading Requirements.  The Plan shall
               ----------------------------------------------
be subject to all applicable laws, rules and regulations, including, but not
limited to, federal and state laws, rules and regulations, and to such approvals
by any regulatory or governmental agency as may be required.

          (c)  Taxes.  The Company is authorized to withhold from any payment
               -----
made under this Plan any amounts of withholding and other taxes due in
connection therewith, and to take such other action as the Company may deem
advisable to enable the Company and a Director to satisfy obligations for the
payment of any withholding taxes and other tax obligations relating thereto.
<PAGE>
 
                                      -5-

          (d)  Amendment.  The Board may amend, alter, suspend, discontinue, or
               ---------
terminate the Plan without the consent of shareholders of the Company or
individual Directors; provided, however, that, without the consent of an
affected Director, no amendment, alteration, suspension, discontinuation, or
termination of the Plan may impair the rights or, in any other manner, adversely
affect the rights of such Director hereunder.

          (e)  Unfunded Status of Awards.  This Plan (other than Section 4
               -------------------------
hereof) is intended to constitute an "unfunded" plan of deferred compensation.
With respect to any payments not yet made to a Director, nothing contained in
the Plan shall give any such Director any rights that are greater than those of
a general creditor of the Company; provided, however, that the Company may
authorize the creation of trusts or make other arrangements to meet the
Company's obligations under the Plan to deliver cash, or other property pursuant
to any award, which trusts or other arrangements shall be consistent with the
"unfunded" status of the Plan unless the Company otherwise determines with the
consent of each affected Director.

          (f)  Nonexclusivity of the Plan.  The adoption of the Plan by the
               -------------------------- 
Board shall not be construed as creating any limitations on the power of the
Board to adopt such other compensation arrangements as it may deem desirable,
including, without limitation, the granting of options on Shares and other
awards otherwise than under the Plan, and such arrangements may be either
applicable generally or only in specific cases.

          (g)  Adjustments.  In the event that subsequent to the Effective Date
               -----------
any dividend in Shares, recapitalization, Share split, reverse split,
reorganization, merger, consolidation, spin-off, combination, repurchase, or
share exchange, or other such change, affects the Shares such that they are
increased or decreased or changed into or exchanged for a different number or
kind of Shares, other securities of the Company or of another corporation or
other consideration, then in order to maintain the proportionate interest of the
Directors and preserve the value of the Directors' Share units, there shall
automatically be substituted for each Share unit a new unit representing the
number and kind of Shares, other securities or other consideration into which
each outstanding Share shall be changed or for which each such Share shall be
exchanged. The substituted units shall be subject to the same terms and
conditions as the original Share units.

          (h)  No Right to Remain on the Board.  Neither the Plan nor the
               -------------------------------
crediting of Share units under the Plan shall be deemed to give any individual a
right to remain a director of the Company or create any obligation on the part
of the Board to nominate any Director for reelection by the shareholders of the
Company.
<PAGE>
 
                                      -6-

          (i)  Governing Law.  The validity, construction, and effect of the
               --------- ---
Plan shall be determined in accordance with the laws of the State of New York
without giving effect to principles of conflict of laws.

          (j)  Effective Date.  The Plan shall become effective as of January 1,
               --------------
1997 (the "Effective Date").

          (k)  Titles and Headings.  The titles and headings of the Sections in
               -------------------
the Plan are for convenience of reference only. In the event of any conflict,
the text of the Plan, rather than such titles or headings, shall control.

Dear Mark,

You are invited to accept the amendments, set out below, to your Service
Agreement dated 1st January 1995.

On agreeing to and accepting these changes your Service Agreement, together with
this statement and the Company Handbook, will form your terms and conditions of
employment.

The words defined in your service agreement shall have the same meaning when
used in this statement.

1.   The period of time for which any restrictive covenants in your service
     agreement are expressed to apply after the Termination Date shall be
     reduced by the amount of time, if any, which you are placed on "gardening
     leave" prior to the Termination Date under your service agreement.

2.   With regard to the restrictive covenants contained in the first schedule to
     your service agreement, the Company confirms that insofar as the Board
     refuse consent pursuant to paragraph 3 of that Schedule or give such
     consent on a qualified basis which effectively prohibits you from working
     during the Restriction Period, the Company shall pay you monthly in arrears
     during the Restriction Period an amount equal to your monthly salary
     pursuant to clause 3.1 of your service agreement immediately prior to the
     Termination Date.
<PAGE>
 
Provided always that:

     a)   The Company shall have no obligation to pay you pursuant to this
          letter if your employment with the Company shall have been terminated
          pursuant to clause 12.1.2 of your service agreement;

     b)   you continue to observe the obligations in your service agreement
          which survive the Termination Date; and

     c)   you shall not be entitled to any other benefits during any such
          Restriction Period including but not limited to pension and insurance
          benefits.

The remainder of your terms and conditions of employment are unaltered.

To confirm your agreement to these amendments please sign, date and return to me
the enclosed copy of this letter.

Yours sincerely,

KJ ALLEN

I accept the amendments to the Service Agreement set out in this statement.

Dear Sirs,

                                 Use of Names
                                 ------------

          I refer to the Subscription and Shareholders' Agreement between
Brockbank Group Plc ("Brockbank Group"), Mid-Ocean Limited, Mid-Ocean
Reinsurance Company Ltd. and Balrusrol dated today (the "Shareholders
Agreement") and the Agreement for the Sale and Purchase dated yesterday of the
business and assets of Brockbank Group between Brockbank Group and Brockbank
Underwriting Limited (the "Hivedown Agreement").

          I hereby undertake that for the period of 5 (five) years from the date
of completion of the Shareholders Agreement I shall not carry on any business
which competes or is likely to compete with the business of Brockbank
Underwriting or any holding company or subsidiary of Brockbank Underwriting (the
"Restricted Business") under or by reference to the name (and/or trade mark)
"Brockbank" and shall not directly or indirectly assist or be involved in any
business which conducts the Restricted Business.  I further agree for such
period not to licence or purport to license the "Brockbank" name to any person
in connection with any Restricted Business.

          I recognise that this restriction is reasonable in connection with the
transactions contemplated by the agreements referred to above and that any use
of the name Brockbank which would breach or infringe the undertaking given by me
above would not be legitimate or bona fide.

          This document is intended to create a legally binding undertaking and
shall be construed in accordance with English law.

          I intend this document to be a deed and execute and deliver it as a
deed.

          --------  -------
          comparable coverage provided to the Executive in connection with
          subsequent full-time employment and, to the extent the Company or
          Parent is unable to continue such coverage, the Company or Parent
          shall provide the Executive with economically equivalent benefits
          determined on an after-tax basis, and

                   (E)  any other rights and benefits available under employee

     continued coverage shall be offset by comparable coverage provided to the
     Executive in connection with subsequent full-time employment and, to the
     extent the Company or Parent is unable to continue such coverage, the
     Company or Parent shall provide the Executive with economically equivalent
     benefits determined on an after-tax basis, and

          (F) any other rights and benefits available under employee benefit

               --------------                                             
     period of 12 months thereafter, the Executive shall not engage in any
     activities in Bermuda if such activities involve business that is
     competitive with that being conducted by the Company or Parent. For

     include any entity that was an Affiliate of the Company or Parent during
     the period of the Executive's employment as well as the time in question.

     written consent of the Board or a person authorized by the Board, disclose
     to any person, other than an employee of the Company or Parent or other
     person to whom disclosure is necessary to the performance by the Executive
     of his duties in the employ of the Company or Parent, any confidential
     proprietary information about the
<PAGE>
 
                                     -19-

     Company Parent or an Affiliate or their respective businesses, unless and
     until such information has become known to the public generally (other than
     as a result of unauthorized disclosure by the Executive) or unless he is
     required to disclose such information by a court or by a governmental body
     with apparent authority to require such disclosure. The foregoing covenant
     by the Executive shall be without limitation as to time and geographic
     application.

13.  WITHHOLDING.
     ----------- 

               Anything in this Agreement to the contrary notwithstanding, all
     payments required to be made by the Company or Parent hereunder to the
     Executive shall be subject to withholding of such amounts relating to taxes
     as the Company or Parent may reasonably determine it should withhold
     pursuant to any applicable law or regulation.  In lieu of withholding such
     amounts, in whole or in part, the Company or Parent may, in its sole
     discretion, accept any other provision for payment of taxes as required by
     law, provided it is satisfied that all requirements of law affecting its
     responsibilities to withhold such taxes have been satisfied.

     person or group which are convertible or exchangeable into securities
     carrying voting rights have been converted or exchanged and all options,

               in connection with subsequent employment or other service and, to
               the extent the Company or Parent is unable to continue such
               coverage, the Company shall provide the Executive with

               fraction thereof in which the Executive was employed by the
               Company and Parent in such year, and the denominator of which is
               12,

               coverage, the Company or Parent shall provide the Executive with
               economically equivalent benefits determined on an after-tax
               basis, and
<PAGE>
 
                                     -17-

                    (F)  other rights and benefits available to him under
               employee benefit programs of the Company or Parent, or their
               equivalent, as provided in Section 6, above, and under business
               expense reimbursement and fringe benefit programs as described in
               Section 7, above, determined in accordance with the applicable
               terms and provisions of such programs.

               (iv)   If, at any time during the term of the Executive's
          service hereunder, the Executive fails to be elected (or re-elected,
          as appropriate) as Chairman of the Board and the Parent Board, or is
          otherwise removed from the Board and the Parent Board involuntarily,
          or fails to be appointed (or reappointed, as appropriate) to the
          Executive Committee of the Board and the Parent Board, the Executive
          shall have the right to terminate his service, and, if prior to a
          Change in Control, such termination shall be deemed a termination by
          the Company and Parent without Cause under Section 8(d)(ii), above,
          or, if following a Change in Control, such termination shall be deemed
          a termination without Cause under Section 8(d)(iii), above, provided
          the Executive, in either case, shall have given the Company and Parent
          written notice of his decision and shall not within 10 business days
          thereafter have been reinstated to the relevant positions.

                                     -18-

          (E)  VOLUNTARY TERMINATION BY THE EXECUTIVE.  The Executive may
               --------------------------------------                    
voluntarily terminate his service prior to the expiration of the term of his
service under this Agreement.  Such termination shall constitute a voluntary
termination and, except as provided in Section 8(d)(iii), in such event the
Executive shall be limited to the same rights and benefits as applicable to a
termination by the Company for Cause as provided in Section 8(c), above.  A
voluntary termination under this Section 8(e) shall not be deemed a breach of
this Agreement.  A termination of the Executive's service due to disability as
described in Section 8(b), above, a termination by the Executive which the
Executive is entitled to treat as & termination by the Company pursuant to
Section 8(d)[ or 8(e)], above, or a termination by the Executive under Section
8(d)(iii), above, shall not be deemed a voluntary termination within the meaning
of this Section 8(e).

          9.   NO-MITIGATION; NO OFFSET.
               ------------------------ 

          In the event of any termination of service under Section 8, above, the
Executive shall be under no obligation to seek other employment, and there shall
be no offset against amounts due the Executive under this Agreement on account
of any remuneration attributable to any subsequent employment that he may
obtain.

          10.  NONCOMPETITION AND NONSOLICITATION.
               ---------------------------------- 

               (A)  NONCOMETITION. During the term of his service and, except in
                    -------------
the case of a termination of the term of his service pursuant to Section 8(d) or
(e), above, for a period of 12 months thereafter, the Executive shall not,
directly or indirectly, whether as an employee, consultant, partner, principal,
agent, distributor, representative or stockholder (except as a less than one
percent stockholder of a publicly traded company or a less than five percent
stockholder of a privately held company), engage in any activities within the
United States or Bermuda if such activities involve insurance or reinsurance of
United States based entities or exposures that are competitive with the
businesses that (i) are then being conducted by the Company or Parent and (ii)
during the period of the Executive's service were either being conducted by the
Company or Parent or actively being developed by the Company or Parent. The
Executive's service as a director of any company in the insurance, reinsurance
or related businesses shall not be deemed engaging in any activity that is
competitive within the meaning of the preceding sentence. For purposes of this
Section 10, the Company or Parent shall be deemed to include any entity that was
affiliated with the Company or Parent during the period of the Executive's
service as well as the time in question (meaning any entity 50% of the equity in
<PAGE>
 
                                     -20-

which is owned by the Company or Parent during the period of the Executive's
service as well as the time in question).

          (B)  NONSOLICITATION. During the term of the Executive's service under
               ---------------  
this Agreement, and for a period of 12 months following termination of service,
the Executive shall not encourage any employee of the Company or Parent to leave
the employ of the Company or Parent except as may be in the interests of the
Company or Parent during the course of carrying out his duties under Section 2,
above.

     11.  CONFIDENTIAL INFORMATION.
          ------------------------ 

     The Executive covenants that he shall, not, without the prior written
consent of the Board or Parent Board or a person authorized by the Board or
Parent Board, disclose to any person, other than an employee of the Company or
Parent or other person to whom disclosure is necessary to the performance by the
Executive of his duties in the service of the Company or Parent, any
confidential proprietary information about the Company or Parent or their
business, unless and until such information has become known to the public
generally (other than as a result of unauthorized disclosure by the Executive)
or unless he is required to disclose such information by a court or by a
governmental body with apparent authority to require such dis-
<PAGE>
 
                                     -21-

closure. The foregoing covenant by the Executive shall be without limitation as
to time and geographic application.

          12.  WITHHOLDING.
               ----------- 

          Anything in this Agreement to the contrary notwithstanding, all
payments required to be made by the Company or Parent hereunder to the Executive
shall be subject to withholding of such amounts relating to taxes as either the
Company or Parent may reasonably determine it should withhold pursuant to any
applicable law or regulation.  In lieu of withholding such amounts, in whole or
in part, either the Company or Parent may, in its sole discretion, accept other
provision for payment of taxes as required by law, provided it is satisfied that
all requirements of law affecting in its responsibilities to withhold such taxes
have been satisfied.

          13.  PARENT SERVICES.
               --------------- 

               (A) LIABILITY.  The Parent hereby agrees to be jointly and
                   ---------      
severally liable together with the Company for the payment to the Executive of
his Base Fee, bonus, business expense reimbursement and termination of
employment provisions of this Agreement.
<PAGE>
 
                                     -22-

               (B)  RESPONSIBILITY.  All of the other terms and provisions of
                    --------------
this Agreement relating to the Executive's employment by the Company shall
likewise apply mutatis mutandis to the Executive's employment by the Parent,
               ------- --------
including, without limitation, Sections 1, 6, 7, 8, 9, 10, 11, 12, 17 and 18, it
being understood that if the Executive terminates his service under the Service
Agreement he shall be required to do so with respect to both the Company and the
Parent and that a termination of the Executive's services by the Company or the
Parent shall be deemed a termination by both.

          14.  ENTIRE AGREEMENT.
               ---------------- 

          This Agreement, together with the Exhibits, contains the entire
agreement between the Parties concerning the subject matter hereof and
supersedes all prior agreements, understandings, discussions, negotiations and
undertakings, whether written or oral, between the Company, Parent and the
Executive with respect thereto.

          15.  ASSIGNABILITY; BINDING NATURE.
               ----------------------------- 

          This Agreement shall be binding upon and inure to the benefit of the
Parties and their respective successors, heirs and assigns.  No rights or
obligations of the Executive under this Agreement may be assigned or transferred
by the Executive 
<PAGE>
 
                                     -23-

other than his rights to compensation and benefits hereunder, which may be
transferred by will or operation of law subject to the limitations of this
Agreement. The Parties recognize that the Executive also may transfer his rights
under the Option as therein provided. No rights or obligations of the Company or
Parent under this Agreement may be assigned or transferred by the Company or
Parent except that such rights or obligations may be assigned or transferred
pursuant to a merger or consolidation in which the Company or Parent is not the
continuing entity, or the sale or liquidation of all or substantially all of the
assets of the Company or Parent, provided that the assignee or transferee is the
successor to all or substantially all of the assets of the Company or Parent and
such assignee or transferee assumes the liabilities, obligations and duties of
the Company or Parent, as contained in this Agreement, either contractually or
as a matter of law.

          16.  INDEMNIFICATION.
               --------------- 

          The Executive shall be provided indemnification by each of Parent and
the Company to the maximum extent permitted under the laws of their respective
jurisdictions of incorporation and their respective charter documents.  In
addition, he shall be covered by a directors' and officers' liability policy
with coverage for him to the extent of US$50,000,000.

                                     -24-

          17.  EXCISE TAX ADJUSTMENT PAYMENTS.
               ------------------------------ 

               (A) PAYMENTS.  In the event that it is determined bait any
                   --------   
payment or distribution by the Company or Parent to or for the benefit of
Executive, whether paid or payable or distributed or distributable pursuant to
the terms of this Agreement or otherwise, other than any payment pursuant to
this Section 17(a) (a "PAYMENT"), would be subject to the excise tax imposed by
Section 4999 of the Internal Revenue Code of 1996, as amended (the "CODE"), or
any interest or penalties with respect to such excise tax (such excise tax,
together with any such interest and penalties, are hereinafter collectively
referred to as the "EXCISE TAX"), then Executive shall be entitled to receive
from the Company or Parent, within 15 days following the determination described
in Section 17(b), below, an additional payment ("EXCISE TAX ADJUSTMENT PAYMENT")
in an amount such that after payment by Executive of all applicable Federal,
state and local taxes (computed at the maximum marginal rates and including any
interest or penalties imposed with respect to such taxes), including any Excise
Tax, imposed upon the Excise Tax Adjustment Payment, Executive retains an amount
of the Excise Tax Adjustment Payment equal to the Excise Tax imposed upon the
Payments.

                                     -25-

          (B)  DETERMINATIONS. All determinations required to be made under this
               -------------- 
Section 17, including whether an Excise Tax Adjustment Payment is required and
the amount of such Excise Tax Adjustment Payment, shall be made by KPMG Peat
Marwick LLP, or such other national accounting firm as the Company or Parent may
designate prior to a Change of Control, which shall provide detailed supporting
calculations to the Company and the Executive within 15 business days of the
date of termination of Executive's employment. Except as hereinafter provided,
any determination by KPMG Peat Marwick LLP, or such other national accounting
firm as the Company or Parent may designate prior to a Change of Control, shall
be binding upon the Company, Parent and the Executive. As a result of the
uncertainty in the application of Section 4999 of the Code at the time of the
initial determination hereunder, it is possible that (x) certain Excise Tax
Adjustment Payments will not have been made by the Company or Parent which
should have been made (an "UNDERPAYMENT"), or (y) certain Excise Tax Adjustment
Payments will have been made which should not have been made (an "OVERPAYMENT"),
consistent with the calculations required to be made hereunder. In the event of
an Underpayment, such Underpayment shall be promptly paid by the Company or
Parent to or for the benefit of the Executive. In the event that the Executive
discovers that an Overpayment shall have occurred, the 
<PAGE>
 
                                     -26-

amount thereof shall be promptly repaid to the Company or Parent.

          18.  SETTLEMENT OF DISPUTES.
               ---------------------- 

          Any dispute between the Parties arising from or relating to the terms
of this Agreement or the Executive's service with the Company or Parent shall be
resolved by arbitration held in New York City in accordance with the rules of
the American Arbitration Association.  All costs associated with any
arbitration, including all legal expenses, for both Parties shall be borne by
the Company and Parent.

          19.  Amendment or Waiver.
               ------------------- 

          No provision in this Agreement may be amended unless such amendment is
agreed to in writing, signed by the Executive and by a duly authorized officer
of the Company and Parent.  No waiver by any Party of any breach by any other
Party of any condition or provision of this Agreement to be performed by such
other Party shall be deemed a waiver of a similar or dissimilar condition or
provision at the same or any prior or subsequent time.  Any waiver must be in
writing and signed by the Executive or a duly authorized officer of the Company
and Parent, as the case may be.

          A "Change in Control" shall be deemed to have occurred if:

      (i)   on or after the date hereof, any person (which, for all purposes
            hereof, shall include, without limitation, an individual, sole
            proprietorship, partnership, unincorporated association,
            unincorporated syndicate, unincorporated organization, trust, body
            corporate and a trustee, executor, administrator or other legal

            13(d)(3) of the United States Securities Exchange Act of 1934, as
            amended), becomes the beneficial owner, directly or indirectly, of
            securities of the Parent representing, or acquires the right to
            control or direct, or to acquire through the conversion or exchange
            of securities or the exercise of warrants or other rights to acquire
            securities ("Beneficial Owner"), 20% or more of the combined voting
            power of the Parent's then outstanding securities ("Significant
            Owner") (excluding any person who or group which, together with all
            affiliates and associates of such person or group, would on the 
<PAGE>
 
            date of this Agreement but for this clause be a Significant Owner as
            long as such person or group does not subsequently become the
            Beneficial Owner of any additional securities of the Parent in any
            manner other than a change in the aggregate number of the
            outstanding securities of the Parent, and other than pursuant to any
            purchase or acquisition permitted by the first full paragraph of the
            second page of that Standstill Agreement dated June 2, 1995 between
            Parent and EXEL Limited) and, for the purposes hereof, "voting
            power" means the right to vote for the election of directors; or

      (ii)  at any time subsequent to the execution of this contract there shall
            be elected or appointed to the Parent Board any director or
            directors whose appointment or election by the Parent's shareholders
            was not approved by a vote of at least a majority of the directors
            then still in office who were either directors at the date hereof or
            whose election or appointment or nomination for election was
            previously so approved.

The determination to be made pursuant to clause (i) above shall be made on the
basis that (x) all securities beneficially owned by the person or group or over
which control or direction is exercised by the person or group which are
convertible or ex-

exchanged and all options, warrants, exchange rights or other rights which may
be exercised to acquire securities beneficially owned by the person or group or
over which control or direction is exercised by the person or group have been
exercised, and (y) no such convertible or exchangeable securities have been
converted or exchanged by any other person and no such options, warrants,
exchange rights or other rights have been exercised by any other person.

          For purposes of this Agreement, "Good Reason" shall mean any of the
following (without Executive's express prior written consent):

      (i)    (A) The assignment to Executive of duties materially inconsistent
             with Executive's position (including duties, responsibilities,
             status, titles or offices as set forth in Section 2 hereof); or (B)
             any elimination or reduction of Executive's duties or
             responsibilities except in connection with the termination of
             Executive's employment for Cause, disability or as a result of
             Executive's death or by Executive other than for Good Reason;

      (ii)   The (A) reduction in Executive's Base Salary from the level in
             effect immediately prior to, or (B) payment of an annual bonus in
             an amount less than the most recent annual bonus paid prior to the
             Change in Control;

      (iii)  The failure by the Company or Parent to obtain the specific
             assumption of this Agreement by any successor or assign of Parent
             or the Company or any person acquiring substantially all of the
             Company's or Parent's assets;

      (iv)   Any material breach by the Company or Parent of any provision of
             this Agreement or any agreements entered into pursuant thereto;

      (v)    Requiring Executive to be based at any office or location other
             than those described in Section 2(a) hereof, except for travel
             reasonably required in the performance of the Executive's
             responsibilities; or

     (vi)    During the twelve month period following a Change in Control, (A)
             the failure to continue in effect any compensation plan in which
             Executive participates at the time of the Change in Control unless
             an equitable arrangement (embodied in an ongoing substitute or
             alternative plan providing Executive 
<PAGE>
 
             with substantially similar benefits) has been made with respect to
             such plan in connection with the Change in Control, or the failure
             to continue Executive's participation therein on substantially the
             same basis, both in terms of the amount of benefits provided and
             the level of his participation relative to other participants, as
             existed at the time of the Change in Control; or (B) the failure to
             continue to provide Executive with benefits at least as favorable
             in the aggregate as those enjoyed by him under any of the Company's
             or Parent's pension, life insurance, medical, health and accident,
             disability, deferred compensation or savings plans in which he was
             participating at the time of the Change in Control, the taking of
             any action which would directly or indirectly materially reduce any
             of such benefits or deprive Executive of any fringe benefit enjoyed
             by him at the time of the Change in Control, or the failure to
             provide him with the number of paid vacation days to which he was
             entitled on the basis of the Company's practice with respect to him
             as in effect at the time of the Change in Control.

     The Company shall employ the Executive and the Executive shall
     serve the Company and any applicable Group Company (subject to

     than twelve months' written notice; provided, that, except as
                                         --------
     otherwise set forth in this Agreement, such notice shall not

     The Option shall vest 33 1/3 per cent per year on each of the
     first three anniversaries of the Effective Date, and shall be
     subject to


<PAGE>
                                     -3- 

     the terms and conditions generally applicable to options granted under the

     waives on a pro rata basis, to the extent applicable, accelerated
     exercisability and vesting as a result of the Transactions
     (including shareholder approval of the Transactions) and agrees
     that such options and restricted stock shall continue to vest
     pursuant to their normal schedule; provided, that upon a

     by the Company other than pursuant to Clause 12, the remaining
     balance of such options and shares of restricted stock for which
     accelerated exercisability or vesting was waived shall become
     immediately exercisable and/or vested. The Executive's Restricted
     Mid Ocean Ordinary Shares offered under the Restricted Mid Ocean
     Ordinary Share Alternative shall be replaced by restricted shares
     of Exel Merger Company Ltd. upon the Effective Date pursuant to
     the terms and conditions of the Amalgamation Agreement, and all
     restrictions applicable to such shares shall otherwise continue.

          4.   This amendment to the Service Agreement shall take effect as of

entirety follows:

          (a)  TERMINATION DUE TO DEATH.  In the event the Executive dies during
               ------------------------                                         
     the term of his service under this Agreement, the Executive's spouse, if

<PAGE>
 
                                      -5-

               -----------------------------                               
     service with the Company or Parent is terminated due to his disability, as
     determined pursuant to the definition under the Company's or Parent's long-
     term disability plan, the Executive shall be entitled to the Base Fee as
     provided in Section 3, above, through the end of the month in which the
     Executive's service terminates due to disability.

          (C)  TERMINATION FOR CAUSE; VOLUNTARY TERMINATION.
               --------------------------------------------

          terminated by the Parent or the Com-
<PAGE>
 
                                      -6-

          pany for Cause or may be voluntarily terminated by the Executive. For
          this purpose, "CAUSE" shall mean:

                    (A)  conviction of the Executive of a felony involving moral
               turpitude, or

                    (B)  the Executive, in carrying out his duties for the
               Company or Parent under this Agreement has been guilty of (I)
               gross neglect or (II) gross misconduct; provided, however, that
                                                       --------  -------      
               any act, or failure to act, by the Executive shall not constitute
               Cause for purposes of this Section 8(c)(i)(B) if such act, or
               failure to act, was committed, or omitted, by the Executive in
               good faith and in a manner he reasonably believed to be in the
               best interests of the Company or Parent.

              (ii)  In the event of a termination for Cause by the Company or
          Parent or a voluntary termination by the Executive under Section
          8(c)(i), above, the Executive shall be entitled only to the Base Fee
          as provided in Section 3, above, at the rate in effect at the time of
          his termination of service for Cause or his voluntary termination,
          through the date on

          which termination for Cause or the voluntary termination occurs.

          (d)  TERMINATION WITHOUT CAUSE.
               -------------------------

          the Executive's service may be terminated without Cause as provided in
          this Section 8(d). A termination due to disability, as described in
          Section 8(b), above, or a termination for Cause, as described in
          Section 8(c), above, shall not be deemed a termination without Cause
          under this Section 8(d).

               (ii) In the event the Executive's service is terminated without
          Cause, Executive shall be entitled to the Base Fee as provided in
          Section 3, above, at the rate in effect in accordance with Section 3,
          above, immediately prior to such termination, payable in equal monthly
          installments until the end of the scheduled term.

          7.    Paragraph 10(b) of the Agreement is hereby amended to add the
following sentence to the end thereof:

     service with the Company or Parent is terminated due to his disability, as

                    (B)  the Executive, in carrying out his duties for the
               Company or Parent under this Agreement, has been guilty of (I)
               gross neglect or (II) gross misconduct; provided, however, that
                                                       --------  -------      
               any act, or failure to act, by the Executive shall not constitute
               Cause for purposes of this Section 9(c)(i)(B) if such act, or
               failure to act, was committed, or omitted, by the Executive in
               good faith and in a manner he reasonably believed to be in the
               best interests of the Company or Parent.

              (ii)  In the event of a termination for Cause by the Company or

               (ii) In the event the Executive's service is terminated without
          Cause, Executive shall be entitled to the Base Fee as provided in

obligated to pay interest on the Required Payment as follows:

have, each Bank shall be entitled, at its option (to the fullest extent
permitted by law), to set-off and apply any deposit (general or special, time or
demand, provisional or final), or other indebtedness, held by it for the credit

of or interest on any Loan and denominated in any Currency owing to it or
payment of any other amount under this Agreement through the exercise of any
right of set-off, banker's lien or counterclaim or similar right or otherwise
(other than from the Administrative Agent, as provided herein), and, as a result
of such payment, such Bank shall have received a greater percentage of the
principal of or interest on the Loans denominated in such Currency (the
"Applicable Loans") or such other amounts then due hereunder by the Company' to

such Bank than the percentage received by any other Bank to which principal of
or interest on the Applicable Loans or such other amounts is then due hereunder
by the Company. it shall promptly purchase from such other Banks participations
in (or. if and to the extent specified by such Bank, direct interests in) the
Applicable Loans or such other amounts, respectively. owing to such other Banks

other adjustments from time to time as shall be equitable, to the end that all
such Banks shall share the benefit of such excess payment (net of any expenses
that may be incurred by such Bank in obtaining or preserving such excess
payment) pro rata in accordance with the unpaid principal of and/or interest on
the Applicable Loans or such other amounts, respectively, owing to each of such
Banks. To such end all such Banks shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if such payment
is rescinded or must otherwise be restored.

          (c) The Company agrees that any Bank so purchasing such a
participation (or direct interest) may exercise all rights of set-off, banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Bank were a direct holder of Loans or other amounts (as the case may
be) owing to such Bank in the amount of such participation (or direct interest).

          (d) Nothing contained herein shall require any Bank to exercise any
such right or shall affect the right of any Bank to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of the Company. If, under any applicable bankruptcy, insolvency or
other similar law, any Bank receives a secured claim in lieu of a set-off to
which this Section 4.07 applies, such Bank shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Banks entitled under this Section 4.07 to share in the
benefits of any recovery on such secured claim.

Agent), suspend the obligation of such Bank thereafter to make Eurocurrency
Loans to such Company until the Regulatory Change giving rise to such request
ceases to be in effect (in which case the provisions of Section 5.03 hereof
shall be applicable), provided that such suspension shall not affect the right

to the Company (with a copy to the Administrative Agent), the obligation of such
Bank to make Eurocurrency Loans in such Currency hereunder shall be suspended
until such Regulatory Change ceases to be in effect (in which case the
provisions of Section 5.03 hereof shall be applicable).

Foreign Currency to the Company shall be suspended pursuant to Section 5.01
hereof, then, unless and until such Bank gives notice as provided below that the
circumstances specified in Section 5.01 hereof that gave rise to such suspension

     Loan to such Bank for any reason (including, without limitation, the
     acceleration of the Loans pursuant to Section 9 hereof) on a date other
     than the last day of the Interest Period for such Loan; or

          (b) any failure by the Company for any reason (including, without
      limitation. the failure of any of the conditions precedent specified in
      Section 6 hereof to be satisfied) to borrow a Eurocurrency Loan from such
      Bank on the date for such borrowing specified in the relevant notice of
      borrowing given pursuant to Section 2.02 hereof.

that otherwise would have accrued on the principal amount so paid, prepaid or
not borrowed for the period ("Relevant Period") from the date of such payment,
                              ---------------

over (ii) the amount of interest that otherwise would have accrued on such
principal amount at a rate equal to the arithmetic mean, as reasonably
determined by such Bank, of the respective rates per annum (rounded upward, if
necessary, to the nearest 1/16 of 1%) of the bid rates for deposits in the
Currency in which such Loan is denominated for the period approximately equal to
the Relevant Period appearing on the Screen or other publicly available source

(including all or a portion of its Commitment and the Loans owing to it);
provided that (i) such Bank's obligations under this Agreement shall remain
- --------
unchanged, (ii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Company and the
other Banks shall continue to deal solely and directly with such Bank in
connection with such Bank's rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Bank sells such a participation
shall provide that such Bank shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
                   --------
such Bank will not, without the consent of the Participant, agree to any
amendment, modification or waiver described in the proviso to Section 11.04 that
affects such Participant. Subject to paragraph (f) of this Section the Company
agrees that each Participant shall be entitled to the benefits of Sections 5.01,
5.04 and 5.05 to the same extent as if it were a Bank and had

To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 4.07(a) as though it were a Bank, provided that any exercise
by any Participant of any such benefits shall constitute the agreement of such
Participant to be subject to Section 4.07(b) as though it were a Bank.

          (f)  A Participant shall not be entitled to receive any greater
payment under Section 5.01 or 5.05 than the applicable Bank would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Company's prior written consent. A Participant shall not be entitled to the
benefits of Section 5.05 unless the Company is notified of the participation
sold to such Participant and such Participant agrees, for the benefit of the
Company, to bound by Section 5.05 as though it were a Bank.

          (g)  In addition to the assignments and participations permitted under
the foregoing provisions of this Section 11.06, any Bank may (without notice to
the Company, the Administrative Agent or any other Bank and without payment of
any fee) pledge or grant a security interest in all or any portion of its Loans
to secure any obligations of such Bank (including, without limitation, to any
Federal Reserve Bank as collateral security pursuant to Regulation A and any
Operating Circular issued by such Federal Reserve Bank). No such assignment
shall release the assigning Bank from its obligations hereunder.

          (h)  A Bank may furnish any information concerning the Company or any
of its Subsidiaries in the possession of such Bank from time to time to

RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          11.12   Confidentiality. Each of the Banks and the Administrative
                  ---------------
Agent agrees (on behalf of itself and each of its Affiliates, directors,
officers, employees and representatives) to use reasonable precautions to keep
confidential, in accordance with its customary procedures for handling
confidential information of the same nature and in accordance with safe and
sound banking practices, any non-public information supplied to it by the
Company pursuant to this Agreement that is identified by the Company as being
confidential at the time the same is delivered to the Banks or the
Administrative Agent; provided that nothing herein shall limit the disclosure of
                      --------
any such non-public information (i) to the extent required by statute, rule,
regulation or judicial process, (ii) to counsel for any of the Banks or the
Administrative Agent, (iii) to bank examiners, auditors or accountants, (iv) to
the Administrative Agent or any other Bank (or to Chase Securities Inc.), (v) in
connection with any litigation to which any one or more of the Banks or the
Administrative Agent is a party, (vi) to a subsidiary or Affiliate of such Bank
as provided in paragraph (a) above or (vii) to any assignee or participant (or
prospective assignee or participant) so long as such assignee or participant (or
prospective assignee or participant) first executes and delivers to the
respective Bank a Confidentiality Agreement substantially in the form of Exhibit
C hereto; and provided, further, that in no event shall any Bank or the
              --------
Administrative Agent be obligated or required to return any materials furnished
by the Company. The obligations of any assignee that has executed a
Confidentiality Agreement in the form of Exhibit C hereto shall be superseded by
this Section 11.12 upon the date upon which such assignee becomes a Bank
hereunder pursuant to Section 11.06 hereof.

          11.13   Judgment Currency. This is an international loan transaction
                  -----------------
in which the specification of Dollars or any Foreign Currency, as the case may
be (the "Specified Currency"), and any payment in New York County or the country
         ------------------
of the Specified Currency as the case may be (the "Specified Place"), is of the
                                                   ---------------
essence, and the Specified Currency shall be the currency of account in all
events relating to Loans denominated in the Specified Currency. The payment
obligations of the Company under this Agreement shall not be discharged by an
amount paid in another currency or in another place, whether pursuant to a
judgment or otherwise, to the extent that the amount so paid on conversion to
the Specified Currency and transfer to the Specified Place under normal banking
procedures does not yield the amount of the Specified Currency at the Specified
Place due hereunder. If for the purpose of obtaining judgment in any court it is
necessary to convert a sum due hereunder in the Specified Currency into another
currency (the "Second Currency"), the rate of exchange which shall be applied
               ---------------
shall be that at which in accordance with normal banking procedures the
Administrative Agent could purchase the Specified Currency with the Second
Currency on the Business Day next preceding that on which such judgment is
rendered. The obligation of the Company in respect of any such sum due from it
to the Administrative Agent or any Bank

hereunder shall, notwithstanding the rate of exchange actually applied in
rendering such judgment, be discharged only to the extent that on the Business
Day following receipt by the Administrative Agent or such Bank, as the case may
be, of any sum adjudged to be due hereunder in the Second Currency to the
Administrative Agent or such Bank, as the case may be, the Administrative Agent
or such Bank, as the case may be, may in accordance with normal banking
procedures purchase and transfer to the Specified Place the Specified Currency
with the amount of the Second Currency so adjudged to be due: and the Company
hereby, as a separate obligation and notwithstanding any such judgment, agrees
to indemnify the Administrative Agent or such Bank, as the case may be,
against, and to pay the Administrative Agent or such Bank, as the case may be,
on demand in the Specified Currency, any difference between the sum originally
due to the Administrative Agent or such Bank. as the case may be, in the
Specified Currency and the amount of the Specified Currency so purchased and
transferred.

                  11.14 European Monetary Union. (a) If, as a result of the
                        -----------------------
implementation of European monetary union, (i) any European Currency ceases to
be lawful currency of the nation issuing the same and is replaced by a European
common currency (the "Euro"), or (ii) any European Currency and the Euro are at
the same time recognized by any Governmental Authority of the nation issuing
such European Currency as lawful currency of such nation and the Administrative
Agent or the Majority Banks shall so request in a notice delivered to the
Company, then any amount payable hereunder by any party hereto in such European
Currency shall instead be payable in the Euro and the amount so payable shall be
determined by translating the amount payable in such European Currency to the
Euro at the exchange rate recognized by the European Central Bank for the
purpose of implementing European monetary union. Prior to the occurrence of the
event or events described in clause (i) or (ii) of the preceding sentence, each
amount payable hereunder in any European Currency will, except as otherwise
provided herein, continue to be payable only in that Currency.

                  (b) The Company agrees, at the request of any Bank, to
compensate such Bank for any loss, cost, expense or reduction in return that
such Bank shall reasonable determine shall be incurred or sustained by such Bank
as a result of the implementation of European monetary union and that would not
have been incurred or sustained but for the transactions provided for herein. A
certificate of a Bank setting forth such Bank's determination of the amount or
amounts necessary to compensate such Bank shall be delivered to the Company and
shall be conclusive absent manifest error so long as such determination is made
on a reasonable basis. The Company shall pay such Bank the amount shown as due
on any such certificate within 10 days after receipt thereof.

                  (c) The parties hereto agree, at the time of or at any time
following the implementation of European monetary union, to use reasonable
efforts to enter into an agreement amending this Agreement in order to reflect
the implementation of such monetary

union, to permit (if feasible) the Euro to qualify as an Agreed Foreign
Currency under the terms and conditions of the definition of such term and to
place the parties hereto in the position with respect to the settlement of
payments of the Euro as they would have been with respect to the settlement of
the Currencies it replaced.

         (without duplication) interest in respect of the Required Payment at
         the Post-Default Rate (without duplication of the obligation of such
         Company under Section 3.02 hereof to pay interest on the Required
         Payment at the Post-Default Rate), it being understood that the return
         by the recipient(s) of the Required Payment to the Administrative Agent
         shall not limit such obligation of the Company under said Section 3.02
         to pay interest at the Post-Default Rate in respect of the Required
         Payment; and

         Loan to be made by the Banks to the Company, the Payor and the Company

         (without duplication) interest in respect of the Required Payment at
         the rate applicable to such Loan pursuant to Section 3.02 hereof, it
         being understood that the return by the Company of the Required Payment
         to the Administrative Agent shall not limit any claim the Company may
         have against the Payor in respect of such Required Payment.

                  (a)  The Company agrees that, in addition to (and without
limitation of) my right of set-off, banker's lien or counterclaim a Bank may
otherwise have, each Bank shall be entitled, at its option (to the fullest
extent permitted by law), to set-off and apply any deposit (general or special,
time or demand, provisional or final), or other indebtedness, held by it for the
credit or account of the Company at any of such Bank's offices, in Dollars or in
any other currency, against any principal of or interest on any of such Bank's
Loans or any other amount payable to such Bank hereunder, that is not paid when
due (regardless of whether such deposit or other indebtedness is then due to the
Company), in which case it shall promptly notify the Company and the
Administrative Agent thereof, provided that such Bank's failure to give such
                              --------
notice shall not affect the validity thereof.

          (b) If any Bank shall obtain from the Company payment of any principal
of or interest on any Loan and denominated in any Currency owing to it or
payment of any other amount under this Agreement through the exercise of any
right of set-off, banker's lien or counterclaim or similar right or otherwise
(other than from the Administrative Agent as provided herein), and, as a result
of such payment, such Bank shall have received a greater percentage of the
principal of or interest on the Loans denominated in such Currency (the
"Applicable Loans") or such other amounts then due hereunder by the Company to
such Bank than the percentage received by any other Bank to which principal of
or interest on the Applicable Loans or such other amounts is then due hereunder
by the Company, it shall promptly purchase from such other Banks participations
in (or, if and to the extent specified by such Bank, direct interests in) the
Applicable Loans or such other amounts, respectively, owing to such other Banks
(or in interest due thereon, as the case may be) in such amounts, and make such
other adjustments from time to time as shall be equitable, to the end that all
such Banks shall share the benefit of such excess payment (net of any expenses
that may be incurred by such Bank in obtaining or preserving such excess
payment) pro rata in accordance with the unpaid principal of and/or interest on
the Applicable Loans or such other amounts, respectively, owing to each of such
Banks. To such end all such Banks shall make appropriate adjustments among
themselves (by the resale of participations sold or otherwise) if such payment
is rescinded or must otherwise be restored.

          (c) The Company agrees that any Bank so purchasing such a
participation (or direct interest) may exercise all rights of set-off, banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Bank were a direct holder of Loans or other amounts (as the case may
be) owing to such Bank in the amount of such participation (or direct interest).

          (d) Nothing contained herein shall require any Bank to exercise any
such right or shall affect the right of any Bank to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of the Company. If, under any applicable bankruptcy, insolvency or
other similar law, any Bank receives a secured claim in lieu of a set-off to
which this Section 4.07 applies, such Bank shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Banks entitled under this Section 4.07 to share in the
benefits of any recovery on such secured claim.

by reason of Section 5.05(a) hereof) directly to each Bank from time to time
such amounts as such Bank may reasonably determine to be necessary to compensate
such Bank for any costs incurred by such Bank that such Bank reasonably
determines are attributable to its making or maintaining of any Eurocurrency
Loans to the Company or its obligation to make any Eurocurrency Loans to the
Company hereunder, or any reduction in any amount receivable by such Bank
hereunder in respect of any of such Loans or such obligation resulting from any
Regulatory Change that:

                  (i) shall subject such Bank (or its Applicable Lending
         Office for any of such Loans) to any tax, duty or other charge in
         respect of such Loans or changes the basis of taxation of any amounts
         payable to such Bank under this Agreement in respect of any of such
         Loans (excluding changes in the rate of tax on the net income of such
         Bank or of such Applicable Lending Office by any jurisdiction in which
         such Bank is organized or has its principal office or in which such
         Applicable Lending Office is located or carrying on business); or

                  (ii) imposes or increases any reserve, special deposit or
         similar requirements (other than the reserve requirement utilized in
         the determination of the Eurocurrency Rate for such Loan) relating to
         any extensions of credit or other assets of, or any deposits with or
         other liabilities of, such Bank (including, without limitation, any of
         such Loans or any deposits referred to in the definition of
         "Eurocurrency Base Rate" in Section 1.01 hereof), or any commitment of
         such Bank (including, without limitation, the Commitment of such Bank
         hereunder); or

                  (iii) imposes any other material condition affecting this
         Agreement (or any of such extensions of credit or liabilities) or its
         Commitment

(such increases in costs and reductions in amounts receivable being herein
called "Additional Costs").
        ----------------  

If any Bank requests compensation from any Company under this Section 5.01(a),
the Company may, by notice to such Bank (with a copy to the Administrative
Agent), suspend the obligation of such Bank thereafter to make Eurocurrency
Loans to such Company until the Regulatory Change giving rise to such request
ceases to be in effect (in which case the provisions of Section 5.03 hereof
shall be applicable), provided that such suspension shall not affect the right
                      --------
of such Bank to receive the compensation so requested.

                  (b) Without limiting the effect of the provisions of paragraph
(a) of this Section 5.01, in the event that, by reason of any Regulatory Change.
any Bank either (i) incurs Additional Costs based on or measured by the excess
above a specified level of the amount of a category of deposits or other
liabilities of such Bank that includes deposits by reference to which the
interest rate on Eurocurrency Loans denominated in any Currency as determined as
provided in this Agreement or a category of extensions of credit or other assets
of such Bank that includes Eurocurrency Loans denominated in such Currency or
(ii) becomes subject to restrictions on the amount of such a category of
liabilities or assets that it may hold, then, if such Bank so elects by notice
to the Company (with a copy to the Administrative Agent), the obligation of such
Bank to make Eurocurrency Loans in such Currency hereunder shall be suspended
until such Regulatory Change ceases to be in effect (in which case the
provisions of Section 5.03 hereof shall be applicable).

                  (c) Without limiting the effect of the foregoing provisions of
this Section 5.01 (but without duplication), the Company shall pay directly to
each Bank from time to time on request such amounts as such Bank may reasonably
determine to be necessary to compensate such Bank (or, without duplication, the
bank holding company of which such Bank is a subsidiary) for any costs that it
reasonably determines are attributable to the maintenance by such Bank (or any
Applicable Lending Office or such bank holding company) of capital in respect of
its Commitment or Loans pursuant to any law or regulation or any interpretation,
directive or request (whether or not having the force of law and whether or not
failure to comply therewith would be unlawful) of any court or governmental or

unlawful) hereafter issued by any government or governmental or supervisory

Applicable Lending Office or such bank holding company) could have achieved but
for rich law, regulation, interpretation, directive or request).

                  (d) Each Bank shall notify the Company of any event occurring
after the date hereof entitling such Bank to compensation under paragraph (a) or
(c) of this Section 5.01 as promptly as practicable, but in any event within 90
days, after such Bank obtains actual knowledge thereof; provided that (i) if any
Bank fails to give such notice within 90 days after it obtains actual knowledge
of such an event, such Bank shall, with respect to compensation payable pursuant
to this Section 5.01 in respect of any costs resulting from such event, only be
entitled to payment under this Section 5.01 for costs incurred from and after
the date 90 days prior to the date that such Bank does give such notice and (ii)

compensation and will not, in the sole opinion of such Bank, be disadvantageous
to such Bank, except that such Bank shall have no obligation to designate an
Applicable Lending Office located in the United States of America. Each Bank
will furnish to the Company a certificate setting forth in reasonable detail the
basis and amount of each request by such Bank for compensation under paragraph
(a) or (c) of this Section 5.01. Determinations and allocations by any Bank for
purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to
paragraph (a) or (b) of this Section 5.01, or of the effect of capital
maintained pursuant to paragraph (c) of this Section 5.01, on its costs or rate
of return of maintaining Loans or its obligation to make Loans, or on amounts
receivable by it in respect of Loans, and of the amounts required to compensate
such Bank under this Section 5.01, shall be conclusive absent manifest error, so
long as such determinations and allocations are made on a reasonable basis.

any Eurocurrency Base Rate for any Interest Period pursuant to clause (b) of the
definition of "Eurocurrency Base Rate" in Section 1.01 hereof:

                  (a) the Administrative Agent determines, which determination
         shall be conclusive, that quotations of interest rates for the relevant
         deposits referred to in clause (b) of the definition of "Eurocurrency
         Base Rate" in Section 1.01 hereof are not being provided by the
         Reference Bank in the relevant amounts or Currencies or for the
         relevant maturities for purposes of determining rates of interest for
         Eurocurrency Loans referred to in said clause (b) as provided herein;

         conclusive, and notify (or notifies, as the case may be) the
         Administrative Agent that the relevant rates of interest referred to in
         clause (b) of the definition of "Eurocurrency Base Rate" in Section
         1.01 hereof upon the basis of which the rate of interest for
         Eurocurrency Loans denominated in any Currency for such Interest Period
         is to be determined are not likely adequately to cover the cost to such
         Banks (or to such quoting Bank) of making or maintaining Eurocurrency
         Loans denominated in such Currency for such Interest Period;

then the Administrative Agent shall give the Company and each Bank prompt notice
thereof and, so long as such condition remains in effect, the Banks shall be
under no obligation to make additional Eurocurrency Loans denominated in such
Currency.

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

exist, all Loans that would otherwise be made by such Bank as Eurocurrency Loans
denominated in Dollars shall be made instead as Base Rate Loans. If the
obligation of any Bank to make Eurocurrency Loans denominated in any Agreed
Foreign Currency to the Company shall be suspended pursuant to Section 5.01
hereof, then, unless and until such Bank gives notice as provided below that the
circumstances specified in Section 5.01 hereof that gave rise to such suspension
no longer exist, all Loans that would otherwise be made by such Bank to the
Company as Eurocurrency Loans denominated in such Agreed Foreign Currency shall,
except as provided in the immediately preceding sentence, be made instead as
Eurocurrency Loans denominated in Dollars.

          5.04  Compensation. The Company shall pay to the Administrative Agent
                ------------
for account of each Bank, upon the request of such Bank through the
Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Bank) to compensate it for any loss, cost or expense
that such Bank reasonably determines is attributable to:

          (a) any payment or mandatory or optional prepayment, of a Eurocurrency
Loan to such Bank for any reason (including, without limitation, the
acceleration of the Loans pursuant to Section 9 hereof) on a date other than
the last day of the Interest Period for such Loan; or

          (b) any failure by the Company for any reason (including, without
limitation, the failure of any of the conditions precedent specified in Section
6 hereof to be satisfied) to borrow a Eurocurrency Loan from such Bank on the
date for such borrowing specified in the relevant notice of borrowing given
pursuant to Section 2.02 hereof.

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
that otherwise would have accrued on the principal amount so paid, prepaid or
not borrowed for the period ("Relevant Period") from the date of such payment,
                              ---------------
prepayment or failure to borrow to the last day of the then current Interest
Period for such Loan (or, in the case of a failure to borrow, the Interest
Period for such Loan that would have commenced on the date specified for such
borrowing) at the applicable rate of interest for such Loan provided for herein
over (ii) the amount of interest that otherwise would have accrued on such
principal amount at a rate equal to the arithmetic mean, as reasonably
determined by such Bank, of the respective rates per annum (rounded upward, if
necessary, to the nearest 1/16 of 1%) of the bid rates for deposits in the
Currency in which such Loan is denominated for the period approximately equal to
the Relevant Period appearing on the Screen or other publicly available source
(as described in the definition of the term "Eurocurrency Base Raze" in Section
1.01 hereof); provided that if

     request concerning the nationality, residence, identity or connections with

attributable to any act, failure to act or misrepresentation of the Company
(other than any act or failure to act permitted or contemplated hereunder) and
(z) any tax other than a withholding tax unless the Bank's interest in the Loan
became subject thereto solely by reason of such Bank's participation in the
transactions contemplated hereby.

          (b) Within 30 days after paying any amount to the Administrative Agent
or any Bank from which it is required by law to make any deduction or
withholding, and within 30 days after it is required by law to remit such
deduction or withholding to any relevant taxing or other authority, the Company

require that such Requesting Bank transfer all of its right, title and interest

hereunder, and to purchase all of such Requesting Bank's Loans hereunder for
consideration equal to the aggregate outstanding principal amount of such
Requesting Bank's Loans, together with interest thereon to the date of such
purchase and (b) if such Requesting Bank has requested compensation pursuant to
Section 5.01 or 5.05 hereof, such Proposed Bank's aggregate requested
compensation, if any, pursuant to said Section 5.01 or 5.05 with respect to such
Requesting Bank's Loans is lower than that of the Requesting Bank. Subject to

agreement of the Company hereunder the agreements of the Company contained in

Administrative Agent shall give prompt notice thereof to the Banks. The
Administrative Agent shall (subject to Sections 10.01 and 10.07 hereof) take
such action with respect to such Default as shall be directed by the Majority

capacity as a Bank hereunder shall have the same rights and powers hereunder as
any other Bank and may exercise the same as though it were not acting as the
Administrative Agent, and the term "Bank" or "Banks" shall, unless the context
otherwise indicates, include the Administrative Agent in its individual
capacity. Chase (and any successor acting as Administrative Agent)-and its
Affiliates may (without having to account therefor to any Bank) accept deposits
from, lend money to, make investments in and generally engage in any kind of
banking, trust or other business with the Company (and any of its Subsidiaries

at the time, continue to make its own analysis and decisions in taking or not
taking action under this Agreement. The Administrative Agent shall not be

Company of this Agreement or any other document referred to or provided for

expressly required to be furnished to the Banks by the Administrative Agent
hereunder, the Administrative Agent shall not have any duty or responsibility to
provide any Bank with any credit or other information concerning the affairs,
financial condition, operations, business, Properties, liabilities or prospects
of the Company or any of its Subsidiaries (or any of their Affiliates) that may
come into the possession of the Administrative Agent or any of its Affiliates.

          10.07 Failure to Act. Except for action expressly required of the
                --------------

fully justified in failing or refusing to act hereunder unless it shall receive

obligations under Section 10.05 hereof against any and all liability and expense
that may be incurred by it by reason of taking or continuing to take any such
action.

but shall continue to be entitled to the benefits of Sections 5.01, 5.04, 5.05
and 11.03). Any assignment or transfer by a Bank of rights or obligations under

                  (e) Any Bank may, without the consent of the Company, sell
participations to one or more banks or other entities (a "Participant") in all

unchanged, (ii) such Bank shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Company and the

Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
                   --------

and had acquired its interest by assignment pursuant to paragraph (b) of this
Section. To the extent permitted by law, each Participant also shall be entitled
to the benefits of Section 4.07(a) as though it were a Bank, provided that any
exercise by any Participant of any such benefits shall constitute the agreement
of such Participant to be subject to Section 4.07(b) as though it were a Bank.

                  (f) A Participant shall not be entitled to receive any greater
payment under Section 5.01 or 5.05 than the applicable Bank would have been
entitled to receive with respect to the participation sold to such Participant,
unless the sale of the participation to such Participant is made with the
Company's prior written consent. A Participant shall not be entitled to the
benefits of Section 5.05 unless the Company is notified of the participation
sold to such Participant and such Participant agrees, for the benefit of the
Company, to bound by Section 5.05 as though it were a Bank.

permitted under the foregoing provisions of this Section 11.06, any Bank may

without payment of any fee) pledge or grant a security interest in all or any
portion of its Loans to secure any obligations of such Bank (including, without
limitation, to any Federal Reserve Bank as collateral security pursuant to
Regulation A and any Operating Circular issued by such Federal Reserve Bank). No
such assignment shall release the assigning Bank from its obligations hereunder.

assignees and participants (including prospective assignees and participants),
subject, however, to the provisions of Section 11.12(b) hereof.

                  (i) Anything in this Section 11.06 to the contrary
notwithstanding, no Bank may assign or participate any interest in any Loan held
by it hereunder to the Company or any Affiliate or Subsidiary of the Company
without the prior consent of each Bank.

                  11.07 Survival. The obligations of the Company to any Bank
                        -------- 
under Sections 5.01, 5.04, 5.05, and 11.03 hereof, and the obligations of any
Bank under Sections 10.05 and 11.12 hereof, shall survive the repayment of the
Loans made by such Bank and the termination of the Commitment of such Bank
(including, with respect to any Bank that does not agree to the extension of the

notwithstanding that such assigning Bank may cease to be a "Bank" hereunder. In
addition, each representation and warranty made, or deemed to be made by a
notice of any Loan, herein or pursuant hereto shall survive the making of such
representation and warranty, and no Bank shall be deemed to have waived, by
reason of making any Loan, any Default that (i) may arise by reason of such
representation or warranty proving to have been false or misleading or (ii)
exists at the time such Loan was made, notwithstanding that such Bank or the
Administrative Agent may have had notice or knowledge or reason to believe that
such representation or warranty was false or misleading, or that such Default
was existing, at the time such Loan was made.

judgment, be discharged only to the extent that on the Business Day following
receipt by the Administrative Agent or such Bank, as the case may be, of any sum
adjudged to be due hereunder in the Second Currency to the Administrative Agent
or such Bank, as the case may be, the Administrative Agent or such Bank, as the
case may be, may in accordance with normal banking procedures purchase and
transfer to the Specified Place the Specified Currency with the amount of the
Second Currency so adjudged to be due; and the Company hereby, as a separate
obligation and notwithstanding any such judgment. agrees to indemnify the

implementation of European monetary union, (i) any European Currency ceases to
be lawful currency of the nation issuing the same and is replaced by a European
common currency (the Euro"), or (ii) any European Currency and the Euro are at
                     ----
the same time recognized by any Governmental Authority of the nation issuing
such European Currency as lawful currency of such nation and the Administrative
Agent or the Majority Banks shall so request in a notice delivered to the
Company, then any amount payable hereunder by any party hereto in such European
Currency shall instead be payable in the Euro and the amount so payable shall be
determined by translating the amount payable in such European Currency to the
Euro at the exchange rate recognized by the European Central Bank for the
purpose of implementing European monetary union. Prior to the occurrence of the
event or events described in clause (i) or (ii) of the preceding sentence, each
amount payable hereunder in any European Currency will, except as otherwise
provided herein, continue to be payable only in that Currency.

                  (b) The Company agrees, at the request of any Bank, to
compensate such Bank for any loss, cost, expense or reduction in return that
such Bank shall reasonable determine shall be incurred or sustained by such Bank
as a result of the implementation of European monetary union and that would not
have been incurred or sustained but for the transactions provided for herein. A
certificate of a Bank setting forth such Bank's determination of the amount or
amounts necessary to compensate such Bank shall be delivered to the Company and
shall be conclusive absent manifest error so long as such determination is made
on a reasonable basis. The Company shall pay such Bank the amount shown as due
on any such certificate within 10 days after receipt thereof.

following the implementation of European monetary union, to use reasonable
efforts to enter into an agreement amending this Agreement in order to reflect
the implementation of such monetary union, to permit (if feasible) the Euro to
qualify as an Agreed Foreign Currency under the terms and conditions of the
definition of such term and to place the parties hereto in the position with
respect to the settlement of payments of the Euro as they would have been with
respect to the settlement of the Currencies it replaced.

DATE

To the Banks party to the Credit Agreement 
referred to below and
The Chase Manhattan Bank, 
as Administrative Agent

Dear Sirs

Mid Ocean Limited/US$100.000.000 Loan
- -------------------------------------

We have acted as special legal counsel in the Cayman Islands to Mid Ocean
Limited (the "Company") in connection with a loan of up to US$100,000,000 (or
equivalent in other currencies) proposed to be made to the Company by the Banks
(as defined in the Credit Agreement referred to below).

For the purpose of giving this opinion we have examined and relied upon an
executed copy of a Credit Agreement (364-Day) dated September 2, 1997 executed
by the Company and the Banks named therein and The Chase Manhattan Bank, as
Administrative Agent (the "Agreement").

We also have reviewed a copy of the Memorandum and Articles of Association of
the Company, minutes of a meeting of the Company's Board of Directors held on
5th June 1997 certified as a true copy thereof by the Secretary of the Company
on 13th August 1997 (the "Resolutions"), and such other documents and made
enquiries as to questions of law as we have deemed necessary in order to render
the opinions set forth below.

A Certificate of Good Standing for the Company dated [        ] 1997 issued by
the Cayman Islands Registry in respect of the Company as an exempted company
under the laws of the Cayman Islands is attached.

We have conducted a search of the Cause Book of the Grand Court in the Cayman
Islands and have discovered no legal proceedings against the Company within the
Cayman Islands as at [           ].

We do not provide registered office facilities in the Cayman Islands to the
Company. We have not acted generally as its legal adviser, we are not familiar
with its operations or financial affairs and we have not acted in regard to the
transaction referred to in the Agreement save for the purpose of giving this
opinion.
<PAGE>
 
                                      -2-

For the purpose of the provision of this opinion we have assumed without
enquiry:

(1)  the genuineness and authenticity of all signatures and seals and the
     conformity to the originals of all copies of documents (whether or not
     certified) submitted to us and the authenticity and completeness of the
     originals from which such copies were taken;
    
(2)  the capacity, power and authority of each of the parties to the Agreement
     (other than the Company) to enter into and perform its respective
     obligations under the Agreement;
     
(3)  the due execution and delivery of the Agreement by each of the parties
     thereto (other than the Company);
    
(4)  the accuracy and completeness of all factual statements, representations
     and warranties, in each case as to factual matters, made in the Agreement
     which we have relied on without further enquiry;

(5)  that there were no representations or warranties made other than as set out
     in the Agreement;
    
(6)  that the Resolutions of the Directors of the Company are a full and
     accurate record of the Resolutions passed at the meeting, duly convened and
     held by the Directors of the Company in accordance with the Articles of
     Association of the Company at which the Directors declared in writing any
     interest they had in the matters in issue and that such Resolutions have
     not been amended or rescinded and are in full force and effect;
     
(7)  that the Board of Directors of the Company, when passing the resolutions
     referred to in this opinion acted in good faith and having regard to all
     relevant matters, reasonably and honestly believed that the responsibility
     to be assumed by the Company pursuant to the Agreement would be in the
     commercial interest of the Company;
    
(8)  that there is no provision of the law of any jurisdiction, other than the
     Cayman Islands, which would have any implication in relation to the
     opinions expressed herein;
    
(9)  the legality, validity and enforceability under the laws of the State of
     New York (the "Foreign Laws") of the Agreement; and
     
(10) that the choice of the Foreign Laws to govern the Agreement and the
     submission by the Company to the non-exclusive jurisdiction of the United
     States District Court for the Southern District of New York and any New
     York State court sitting in New York County (and any appellate court from
     any thereof) (the "Foreign Courts") is a valid choice and submission under
     the Foreign Laws.

The obligations of the Company under the Agreement:
<PAGE>
 
                                      -3-

(i)      will be subject to the laws from time to time in effect relating to
         bankruptcy, insolvency, liquidation, possessory liens, rights of
         set-off, reorganization, amalgamation, moratorium or any other laws or
         legal procedures, whether of a similar nature or otherwise, generally
         affecting the rights of creditors;

(ii)     will be subject to statutory limitation of the time within which
         proceedings may be brought;

(iii)    will be subject to general principles of equity and, as such, specific
         performance and injunctive relief, being equitable remedies, may not be
         available; and

(iv)     may not be given effect to by a Cayman Islands Court whether or not it
         was applying the Foreign Laws, if and to the extent they constitute the
         payment of an amount which is in the nature of a penalty and not in the
         nature of liquidated damages, and a Cayman Islands Court may stay any
         proceedings commenced in the Cayman Islands against the Company under
         the Agreement if there are other proceedings in respect of the
         Agreement simultaneously under way against the Company in another
         jurisdiction.

We have made no investigation of and express no opinion in relation to the laws
of any jurisdiction other than the Cayman Islands. This opinion is limited to
and is given on the basis of the current law and practice in the Cayman Islands.
This opinion is issued solely for your benefit with respect to the matters
referred to herein and is not to be relied upon by any other person, firm or
entity or in respect of any other matter.

Based upon and subject to the foregoing we are of the opinion that:

I.       The Company is duly incorporated and validly existing under the laws of
         the Cayman Islands and in good standing pursuant to the provisions of
         the Companies Law (1995 Revision).

2.       The Company has the necessary corporate power and authority to enter
         into and perform its obligations under the Agreement and to borrow
         under the Agreement

3.       The Company has taken all corporate action necessary to authorize its
         execution, delivery and performance of the Agreement including the
         borrowing thereunder.

4.       The Agreement has been duly executed and delivered by or on behalf of
         the Company and constitutes the legal, valid and binding obligations of
         the Company in accordance with the terms thereof.

5.       The execution and delivery of the Agreement by the Company thereunder
         and the performance by the Company of its obligations thereunder and
         the borrowings by the Company thereunder will not violate the
         Memorandum and Articles of Association of the Company nor any
         applicable law, regulation, order or decree in the Cayman Islands. No
         provision in the Agreement would appear to constitute a penalty.

                                      -4-

6.       No order, consent, approval, license, authorization or validation of or
         exemption by any governmental or public body or authority of the Cayman
         Islands or any subdivision thereof is required to authorize or is
         required in connection with the execution, delivery, performance or
         enforcement of the Agreement or the borrowing thereunder.

7.       It is not necessary or desirable to ensure the enforceability in the
         Cayman Islands of the Agreement that it be registered in any register
         kept by, or filed with, any governmental or regulatory body in the
         Cayman Islands.

8.       Subject to the payment of nominal stamp duty of $2 if the Agreement is
         executed in or brought into the Cayman Islands, the Agreement is in
         proper legal form under the laws of the Cayman Islands for the
         admissability thereof into evidence in the courts of the Cayman
         Islands.

9.       There is no income or other tax of the Cayman Islands imposed by
         withholding or otherwise on any payments to be made to or by the
         Company under the Agreement.

10.      The Company is not entitled to sovereign immunity under the laws of the
         Cayman Islands, from any legal proceedings, whether in the Cayman
         Islands or elsewhere, to enforce or to collect upon the Agreement,
         including, without limitation, immunity from service, immunity from
         jurisdiction of any court or tribunal or immunity of any of its
         property from attachment prior to entry of judgment or from attachment
         in aid of execution upon a judgment in respect of itself or its
         property.

11.      The Company has the legal capacity to sue and to be sued in its own
         name under the laws of the Cayman Islands.

12.      The choice of the Foreign Laws as the governing law of the Agreement
         will be recognized and applied by the Cayman Islands courts provided
         that such choice was made for bona fides purposes and is effective as a
         matter of the Foreign Laws.

13.      The submission by the Company under the Agreement to the non-exclusive
         jurisdiction of the Foreign Courts is valid and binding upon the
         Company under the laws of the Cayman Islands.

14.      Although there is no statutory enforcement in the Cayman Islands of
         judgments obtained in the Foreign Courts, the courts of the Cayman
         Islands will recognize and enforce a foreign judgment of a court
         recognized as having jurisdiction based on the principle that a
         judgment of a foreign court imposes upon a judgment debtor an
         obligation to pay the sum for which the judgment has been given, and
         provided such judgment is final and conclusive, for a liquidated sum
         not in respect of taxes or a fine or penalty, and which was not
         obtained by a fraud or in a manner, and is not of a kind the
         enforcement of which is, contrary to the public of the policy of the
         Cayman Islands, nor obtained in proceedings which were opposed to
         natural justice.

                                      -5-

15.      We believe that in the event of any proceedings being brought in the
         Cayman Islands courts in respect of a monetary obligation expressed to
         be payable in a currency other than Cayman Islands dollars, a Cayman
         Islands court would give judgment expressed as an order to pay such
         currency or its Cayman Islands dollar equivalent at the time of the
         payment or enforcement of the judgment.  With respect to winding up
         proceedings, Cayman Islands law may require that all claims or debts
         are converted either into Cayman Islands dollars or the Company's
         functional currency of account at the exchange rate ruling at the date
         of commencement of the winding up.

Yours faithfully

DATE

To the Banks party to the Credit Agreement 
referred to below and
The Chase Manhattan Bank, 
as Administrative Agent

Dear Sirs

Mid Ocean Limited/USS100.000.000 Loan
- -------------------------------------

We have acted as special legal counsel in Bermuda to Mid Ocean Limited (the
"Company") in connection with a loan of up to US$100,000,000 (or equivalent in
other currencies) proposed to be made to the Company by the Banks (as defined in
the Credit Agreement referred to below).

For the purpose of giving this opinion we have examined and relied upon an
executed copy of a Credit Agreement (364-Day) dated September 2, 1997 executed
by the Company and the Banks named therein and The Chase Manhattan Bank. as
Administrative Agent (the "Agreement").

We also have reviewed a copy of the Memorandum and Articles of Association of
the Company, minutes of a meeting of the Company's Board of Directors held on
5th June 1997 certified as a true copy thereof by the Secretary of the Company
on 13th August 1997 (the "Resolutions"), and such other documents and made
enquiries as to questions of law as we have deemed necessary in order to render
the opinions set forth below.

A Certificate of Compliance for the Company dated 11th August 1997 issued by the
Registrar of Companies of Bermuda in respect of the Company as an overseas
company with a permit to carry on business in Bermuda is attached.

We have conducted a search of the Cause Book of the Supreme Court of Bermuda and
have discovered no legal proceedings against the Company pending in Bermuda as
at [              ].

We do not provide the principal office of the Company in Bermuda or act as its
principal representative in Bermuda. We have not acted generally as its legal
adviser, we are not familiar with its operations or financial affairs and we
have not acted in regard to the transaction referred to in the Agreement save
for the purpose of giving this opinion.

                                      -2-

For the purpose of the provision of this opinion we have assumed without
enquiry:

(1)  the genuineness and authenticity of all signatures and seals and the
     conformity to the originals of all copies of documents (whether or not
     certified) submitted to us and the authenticity and completeness of the
     originals from which such copies were taken;

(2)  the capacity, power and authority of each of the parties to the Agreement
     to enter into and perform its respective obligations under the Agreement;

(3)  the due execution and delivery of the Agreement by each of the parties
     thereto;

(4)  the accuracy and completeness of all factual statements, representations
     and warranties, in each case as to factual matters, made in the Agreement
     which we have relied on without further enquiry;

(5)  that there were no representations or warranties made other than as set out
     in the Agreement;

(6)  that there is no provision of the law of any jurisdiction, other than
     Bermuda. which would have any implication in relation to the opinions
     expressed herein;

(7)  the legality, validity and enforceability under the laws of the State of
     New York (the "Foreign Laws") of the Agreement; and

(8)  that the choice of the Foreign Laws to govern the Agreement and the
     submission by the Company to the non-exclusive jurisdiction of the United
     States District Court for the Southern District of New York and any New
     York State court sitting in New York County (and any appellate court from
     any thereof) (the "Foreign Courts") is a valid choice and submission under
     the Foreign Laws.

We have made no investigation of and express no opinion in relation to the laws
of any jurisdiction other than Bermuda. This opinion is limited to and is given
on the basis of the current law and practice in Bermuda. This opinion is issued
solely for your benefit with respect to the matters referred to herein and is
not to be relied upon by any other person, firm or entity or in respect of any
other matter.

Based upon and subject to the foregoing we are of the opinion that:

1.   The Company is in good standing (meaning that it has not failed to make any
     filing with any Bermuda governmental authority or to pay any Bermuda
     government fee or tax which might make it liable to be struck off the
     Register of Companies and thereby cease to exist under the laws of Bermuda)
     under the laws of Bermuda.

2.   The execution and delivery of the Agreement by the Company thereunder and
     the performance by the Company of its obligations thereunder and the
     borrowing thereunder will not violate any applicable law, regulation, order
     or decree in Bermuda.

3.   No order, consent, approval, license, authorization or validation of or
     exemption by any governmental or public body or authority of Bermuda or any
     subdivision thereof is required to authorize or is required in connection

4.   It is not necessary or desirable to ensure the enforceability in Bermuda of
     the Agreement that it be registered in any register kept by, or filed with,
     any governmental or regulatory body in Bermuda.

5.   There is no income or other tax of Bermuda imposed by withholding or
     otherwise on any payments to be made to or by the Company under the

     enforce or to collect upon the Agreement, including, without limitation,

     or immunity of any of its property from attachment prior to entry of
     judgment or from attachment in aid of execution upon a judgment in respect
     of itself or its property.

     admissability thereof into evidence in the courts of Bermuda.

     be recognized and applied by Bermuda courts provided that such choice was
     made for bona fides purposes and is effective as a matter of the Foreign
     Laws.

9.   The submission by the Company to the non exclusive jurisdiction of the
     Foreign Courts will be recognized and applied by the Bermuda courts.

10.  The courts of Bermuda would recognize as a valid judgment, a final and
     conclusive ???????????^ obtained in the Foreign Courts against the Company
     based upon the Agreement under which a sum of money is payable (other than
     a sum of money payable in respect of multiple damages, taxes or other
     charges of a like nature or in respect of a fine or other penalty) and

     courts did not contravene the rules of natural justice of Bermuda, (c) such
     judgment was

         [Form of Opinion of Special New York Counsel to the Company]


                                                             September [_], 1997


To the Banks party to the 
  Credit Agreement referred to 
  below and The Chase Manhattan Bank, 
  as Administrative Agent

Ladies and Gentlemen:

          We have acted as special New York counsel to Mid Ocean Limited (the
"Company"), a Cayman Islands corporation, in connection with the Credit
Agreement (364-Day) (the "Credit Agreement") dated as of September 2, 1997,
between the Company, the Banks named therein, and The Chase Manhattan Bank, as
Administrative Agent providing for loans to be made by said lenders to the
Company in an aggregate principal amount not to exceed $100,000,000. Terms
defined in the Credit Agreement are used herein as defined therein. This opinion
is being delivered pursuant to Section 6.01(b) of the Credit Agreement.

          In rendering the opinions expressed below, we have examined the Credit
Agreement.

          In our examination, we have assumed the authenticity of all documents
submitted to us as originals and the conformity with authentic original
documents of all documents submitted to us as copies. When relevant facts were
not independently established, we have relied upon representations made in or
pursuant to the Credit Agreement.

          In our examination, we have assumed, with respect to the Credit
Agreement that:

          (i)   the Credit Agreement has been duly authorized by, has been duly
                executed and delivered by, and (except, to the extent expressly
                set forth in the opinions expressed below, as to the Company)
                constitutes the legal, valid, binding and enforceable
                obligations of, all of the parties thereto;

          (ii)  all signatures to the Credit Agreement have been duly
                authorized; and

          (ill) all of the parties to the Credit Agreement are duly organized
                and validly existing and have the power and authority (corporate
                or other) to execute, deliver and perform the Credit Agreement.

               Opinion of Special New York Counsel to the Company
               --------------------------------------------------
<PAGE>
 
                                      -2-

          Based upon and subject to the foregoing and subject also to the
comments and qualifications set forth below, and having considered such
questions of law as we have deemed necessary as a basis for the opinions
expressed below, we are of the opinion that the Credit Agreement constitutes the
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms, except as may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or transfer or
other similar laws relating to or affecting the rights of creditors generally
(including the judicial application of similar laws of any Company Jurisdiction)
and except as the enforceability of the Credit Agreement is subject to the
application of general principles of equity (regardless of whether considered in
a proceeding in equity or at law), including, without limitation, (a) the
possible unavailability of specific performance, injunctive relief or any other
equitable remedy and (b) concepts of materiality, reasonableness, good faith and
fair dealing.

          The foregoing opinions are subject to the following comments and
qualifications:

          (A)  The enforceability of Section 11.03 of the Credit Agreement may
     be limited by laws limiting the enforceability of provisions exculpating or
     exempting a party, or requiring indemnification of a party for, liability
     for its own action or inaction, to the extent the action or inaction
     involves gross negligence, recklessness, willful misconduct or unlawful
     conduct

          (B)  The enforceability of provisions in the Credit Agreement to the
     effect that terms may not be waived or modified except in writing may be
     limited under certain circumstances.

          (C)  We express no opinion as to (i) the effect of the laws of any
     jurisdiction in which any Bank is located (other than the State of New
     York) that limit the interest, fees or other charges such Bank may impose,
     (ii) Section 4.07(c) of the Credit Agreement, (iii) the second sentence of
     Section 11.10 of the Credit Agreement, insofar as such sentence relates to
     the subject matter jurisdiction of the United States District Court for the
     Southern District of New York to adjudicate any controversy related to the
     Credit Agreement, (iv) the waiver of inconvenient forum set forth in
     Section 11.10 of the Credit Agreement with respect to proceedings in the
     United States District Court for the Southern District of New York, (v)
     Section 11.13 or 11.14(c) of the Credit Agreement and (vi) Section 11.10 of
     the Credit Agreement to the extent it purports to be a waiver of immunity
     acquired after the execution and delivery of the Credit Agreement.

          (D)  We point out with reference to obligations stated to be payable
     in a currency other than Dollars that (i) a New York statute provides that
     a judgment rendered by a court of the State of New York in respect of an
     obligation denominated in any such other currency would be rendered in such
     other currency and would be converted into Dollars at the rate of exchange
     prevailing on the date of entry of the judgment and (ii) a judgment
     rendered by a Federal court sitting in the State of New York in respect of
     an obligation

               Opinion of Special New York Counsel to the Company
               --------------------------------------------------
<PAGE>
 
                                      -3-

     denominated in any such other currency may be expressed in Dollars, but we
     express no opinion as to the rate of exchange such Federal court would
     apply.

          The foregoing opinions are limited to matters involving the Federal
laws of the United States of America and the law of the State of New York, and
we do not express any opinion as to the laws of any other jurisdiction.

          At the request of our clients, this opinion letter is, pursuant to
Section 6.01(b) of the Credit Agreement, provided to you by us in our capacity
as special New York counsel to the Company may not be relied upon by any Person
for any purpose other than in connection with the transactions contemplated by
the Credit Agreement without, in each instance, our prior written consent.

                               Very truly yours,

of this Agreement which shall approximate to the extent possible the economic
effect of the original financial covenants after taking into account such change
in GAAP or SAP, as appropriate.

         (d) Without in any manner limiting the provisions of this Section 1.03,
if any change in GAAP or SAP occurs after the date of this Agreement and such
change in GAAP or SAP could or would materially change the Borrower's financial
results or position from that reflected in such Borrower's financial statements
prior to such change, such Borrower shall notify the Lender as soon as
practicable.

                                   ----------

                                   THE LOANS
                                   ---------

         2.01. The Loans. Subject to the terms and conditions hereof, the Lender
hereby agrees that it will, from time to time prior to the Commitment Expiration
Date, make one or more loans (each a "Loan" and, collectively, the "Loans") to
the Borrower subject to the immediately succeeding sentence. Notwithstanding
anything contained in this Agreement to the contrary, the Lender shall not be
obligated to make any Loan if, after such Loan is made, the Outstanding
Principal Amount exceeds the lesser of (a) the Commitment and (b) the Pledged
Securities Available Amount. The Lender shall remit the proceeds of each Loan to
the Borrower at the principal office of Mellon in immediately available funds.

         2.02. The Note. The Loans shall be evidenced by a promissory note of
the Borrower, substantially in the form of Exhibit A hereto (the "Note"). The
Note shall be payable to the order of the Lender and shall mature on the
Commitment Expiration Date. The Note shall be dated the Closing Date and provide
for the payment of principal and interest in accordance with Section 2.06. The
Borrower hereby authorizes the Lender to make the appropriate notations on the
schedule annexed to the Note for purposes of recording any Loan made thereon and
any payments or prepayments made with respect thereto (provided that any failure
by the Lender to make any such notation shall not affect the obligations of the
Borrower hereunder or under the Note in respect of such Loan). The Borrower
agrees that each notation made by the Lender on the schedule annexed to the Note
shall be final and conclusive absent demonstrable error. The Outstanding
Principal Amount at any time shall constitute the principal amount of the Note
at such time.

         2.03. Loan Request. Whenever the Borrower desires the Lender to make a
Loan, the Borrower shall deliver to the Lender a written request, in
substantially the form of Exhibit B (a "Loan Request"), to the Borrower, no
later than 11:00 A.M., New York City time, at least two Business Days prior to
the date of such Loan. Each Loan Request shall specify the principal amount of
the Loan to be made on the such date (which shall be no less than $10,000,000 or
such lesser amount which the Lender shall have

                                       8
<PAGE>
 
approved). Each Loan Request submitted by the Borrower shall be an affirmation
by the Borrower that (x) the representations and warranties of the Borrower set
forth in Article III of this Agreement are on the date of such Loan Request, and
will be on the date of such Loan, true and correct in all material respects as
if made on and as of such dates, except to the extent any such representation or
warranty relates specifically to an earlier date, and (y) no Unmatured Event or
Event of Termination shall have occurred and be continuing on either of such
dates. Each Loan Request given pursuant hereto shall be irrevocable.

         2.04. Commitment. (a) The Borrower may, upon at least thirty (30) days'
prior written notice to the Lender, terminate in whole or permanently reduce in
part the unused portion of the Commitment; provided, that (i) such termination
shall not be effective unless and until the Outstanding Principal Amount has
been reduced to zero and all Cost of Funds Amount and all other fees or amounts
due to the Lender hereunder have been paid in full, (ii) each partial reduction
shall be in the amount of at least $10,000,000 or an integral multiple thereof,
and (iii) any partial reduction of the Commitment which would result in the
remaining Commitment being less than $25,000,000 shall be deemed to be a
termination in whole of the Commitment.

         (b) If any bank or financial institution which is a party to the
Funding Agreement does not consent to the extension of the expiration date of
its commitment under the Funding Agreement or its commitment thereunder expires
or is terminated for any reason, to the extent such bank or financial
institution is not replaced on or prior to such expiration date, then the
Commitment shall be reduced by such amount as shall be necessary to cause the
Commitment to be equal to the aggregate of all commitments of banks and/or
financial institutions under the Funding Agreement(s) after giving effect to
such termination or expiration.

         (c) The Lender will not: (i) without the consent of the Borrower,
voluntarily agree to any termination of the Funding Agreement prior to its
stated expiration date; (ii) without the consent of the Borrower, voluntarily
agree to any reduction in the amount of any commitment under the Funding
Agreement; or (iii) without the consent of the Borrower, which will not be
unreasonably withheld, amend the Funding Agreement.

         2.05. Mandatory and Optional Prepayments. (a) The Borrower may on a
Settlement Date prepay the Loans, in whole or in part, without premium or
penalty, upon at least 30 days' irrevocable prior written notice to the Lender
in the case of a prepayment in whole or at least three (3) Business Days'
irrevocable prior written notice to the Lender in the case of a partial
prepayment; provided, that each partial prepayment shall be in the amount of at
least $10,000,000 or an integral multiple thereof; provided, further, that the
Borrower shall (i) simultaneously pay to the Lender, and indemnify the Lender
and hold the Lender harmless from, all costs and expenses incurred by the Lender
in connection with such prepayment, and (ii) indemnify the Lender and hold the
Lender harmless from any funding loss (in an amount equal to the amount of
interest the Lender would have received (calculated with respect to the
applicable fixed interest, discount or carrying cost period with respect to the
relevant Cost of Funds) but for such prepayment less the interest earned on
investing such funds) and expense which the Lender may sustain or incur as a
consequence of such prepayment. Any such prepayment of the Loans shall be
accompanied by, without duplication of the preceding sentence, a payment of all
accrued but unpaid interest on the Loans through the date of prepayment, plus
all accrued but unpaid fees, expenses and other amounts due to the Lender
arising under or in connection with this Agreement and the Note through the date
of prepayment.

         (b) If, after giving effect to any reduction of the Commitment pursuant
to Section 2.04(b) above, the Outstanding Principal Amount shall exceed the
Commitment, the Borrower shall, within one Business Day of its receipt of
written notice of the reduction of the Commitment, make a prepayment in respect
of the principal of the Loans in an amount equal to the excess of the
Outstanding Principal Amount over the Commitment as so reduced, accompanied by a
payment of all accrued but unpaid interest on such amount through the date of
such prepayment.

         (c) If at any time the Pledged Securities Available Amount is less than
the Outstanding Principal Amount, the Borrower shall, within one Business Day of
its receipt of written notice thereof, make a

                                       9
<PAGE>
 
prepayment in respect of the principal of the Loans in an amount equal to the
excess of the Outstanding Principal Amount over the Pledged Securities Available
Amount accompanied by a payment of all accrued but unpaid interest on such
amount through the date of such prepayment.

         2.06.  Interest; Fees.  On each Settlement Date, the Borrower
shall make the following cash payments:

                  (i)  to the Lender as interest on the Loans, all accrued and
         unpaid Cost of Funds Amount; and

                  (ii) to the Lender, all accrued and unpaid amounts due and
         payable to the Lender under this Agreement not described in clause (i)
         above, including without limitation, the Program Fee and the Facility
         Fee.

         2.07.  Proceeds.  The proceeds of each Loan shall be used by the
Borrower solely for general corporate purposes.

         2.08. Taxes. All payments made by the Borrower under this Agreement and
the Note shall be made free and clear of, and without deduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, hereafter
imposed, levied, collected, withheld or assessed by the Government of the United
States or any political subdivision thereof having taxing authority, excluding
(i) income and withholding taxes (including, without limitation, branch profits
taxes, minimum taxes and taxes computed under alternative methods, at least one
of which is based on net income) and franchise taxes (imposed in lieu of income
taxes) imposed on the net income of the Lender as a result of any present or
former connection between the jurisdiction imposing such tax or any political
subdivision or taxing authority thereof or therein and the Lender other than a
connection resulting solely from this Agreement and the transactions
contemplated hereby; and (ii) any Taxes that would not have been imposed but for
the failure of the Lender to provide and keep current any certification or other
documentation required to qualify for an exemption from or reduction in the rate
of any Tax (all such excluded taxes described in clause (i) or (ii) above being
hereinafter called "Excluded Taxes" and all such non-Excluded Taxes, levies,
imposts, duties, charges, fees, deductions and withholdings being hereinafter
called "Taxes"). If any Taxes are required to be deducted or withheld from any
amounts payable to or under the Note, the amounts so payable to the Lender shall
be increased to the extent necessary to yield to the Lender (after payment of
all Taxes on such increased amounts) the amount that would have been otherwise
been received by the Lender had not such deduction or withholdings been imposed.
Whenever any Taxes are payable by the Borrower, as promptly as possible
thereafter the Borrower shall send to the Lender a certified copy of an original
official receipt received by the Borrower showing payment thereof. If the
Borrower fails to pay any Taxes when due to the appropriate taxing authority or
fails to remit to the Lender the required receipts or other required documentary
evidence, the Borrower shall indemnify the Lender for any incremental Taxes,
interest or penalties that the Lender is legally required to pay as a result of
any such failure. Such indemnification shall be made within 30 days from the
date the Lender makes written demand therefor. If the Lender receives any refund
or credit in respect of any Taxes with respect to which the Borrower has made
full payment to the Lender pursuant to this Section 2.08, it shall pay over such
refund and remit such credit to the Borrower, net of all out-of-pocket expenses
incurred by the Lender in obtaining such refund or credit and without interest.
The agreements in this subsection shall survive the termination of this
Agreement and the payment of the Note.

         2.09. Increased Cost and Reduced Return. (a) If any Affected Party
shall be charged any fee, expense or increased cost other than relating to Taxes
or Excluded Taxes on account of the adoption after the date hereof of any
applicable law, rule, regulation or guideline (including any applicable law,
rule, regulation or guideline regarding capital adequacy) or any change therein
after the date hereof, or any change after the date hereof in the interpretation
or administration thereof by any Official Body, central bank or comparable
agency: (i) which subjects such Affected Party to any charge or withholding on
or with respect to the Funding Agreement or a Program Support Agreement, as the
case may be, or such Affected

                                       10
<PAGE>
 
Party's obligations under the Funding Agreement or Program Support Agreement, as
the case may be, or on or with respect to this Agreement or the Loans, or
changes the basis of taxation to any Affected Party of any amounts payable under
the Funding Agreement, a Program Support Agreement or this Agreement (except for
changes in the rate of tax on the overall net income of such Affected Party), or
(ii) which imposes, modifies or deems applicable any reserve, assessment,
insurance charge, special deposit or similar requirement against assets of,
deposits with or for the account of, or credit extended by, an Affected Party
under the Funding Agreement or a Program Support Agreement, as the case may be,
or (iii) which imposes any other condition the result of which is (x) to
increase the cost to such Affected Party of performing its obligations, or (y)
to reduce the rate of return on such Affected Party's capital as a consequence
of its obligations, in each case under the Funding Agreement or a Program
Support Agreement, as the case may be, or to reduce the amount of any sum
received or receivable by such Affected Party, or to require any payment
calculated by reference to the amount of interests or loans held or interest
received by it, in each case under the Funding Agreement or a Program Support
Agreement, as the case may be, then, upon demand by the Lender, the Borrower
shall be obligated to immediately pay to the Lender, for the benefit of such
Affected Party, such amounts charged to such Affected Party or to compensate
such Affected Party for such increase, reduction or imposition; provided,
however, that, to the extent that any such amount with respect to an Affected
Party under a Program Support Agreement (other than Mellon Bank, N. A.) exceeds
the amount the Borrower would have been obligated to pay to Mellon Bank, N. A.
if Mellon Bank, N. A. had taken the place of such Affected Party under such
Program Support Agreement, the Borrower shall not be obligated to pay to the
Lender the amount of such excess.

         (b) The Lender agrees that it shall use reasonable efforts to take any
action that will avoid the need to pay, or reduce the amount of, any increased
amounts referred to in this Section 2.09; provided that the Lender shall not be
obligated to take any actions that would, in the Lender's sole discretion, be
materially disadvantageous to the Lender. In the event that any Affected Party
claims any increased costs referred to in this Section 2.09, the Lender will
furnish to the Borrower a certificate setting forth the basis and amount of each
request by such Affected Party for any such increased amounts referred to in
paragraph (a) of this Section 2.09. Determinations by the Lender of any
increased amounts referred to in paragraph (a) of this Section 2.09 shall be
conclusive, absent manifest error. In the event that any Affected Party claims
any increased costs referred to in this Section 2.09 or payments under Section
2.08, the Borrower may, upon payment of such amounts and prepayment of Loans
equal to all amounts owing to such Affected Party with respect to its funding
under the Funding Agreement, and upon reduction of the Lender's commitment
hereunder by an amount equal to such Affected Party's commitment under the
Funding Agreement, and subject to the second proviso of Section 2.05(a) hereof,
require the Lender to cause such Affected Party to cease to be a party to the
Funding Agreement.

                                  -----------

                        REPRESENTATIONS AND WARRANTIES.
                        -------------------------------

Each Credit Party represents and warrants that:

         3.01. Organization and Qualification. Such Credit Party and each of its
Subsidiaries are corporations duly organized, validly existing and in good
standing under the laws of their respective jurisdictions of incorporation; each
of such Credit Party and its Subsidiaries have the power and authority to own
its properties and assets, and to carry on its business as presently conducted
and is qualified to do business in those jurisdictions in which its ownership of
property or the nature of its business activities is such that failure to
receive or retain such qualification would have a Material Adverse Effect. A
list of such Credit Party's Subsidiaries setting forth their respective
jurisdictions of incorporation is set forth in Schedule 3.01 hereto. Such Credit
Party is not subject to any Private Act other than the X.L. Insurance Company,
Ltd. Act, 1989, a copy of which has been provided to Lender.

position of such Credit Party and its consolidated Subsidiaries as of the date
of such reports and the consolidated and consolidating results of their
operations and cash flows for the fiscal period then ended in conformity with
GAAP applied on a consistent basis, and such consolidated financial statements
have been examined and reported upon by independent, certified public
accountants.

         3.04. Litigation. Except as disclosed to the Lender in writing prior to
the Closing Date (including by disclosure in the financial statements delivered
to the Lender referred to in Section 3.03 hereof), there is no litigation or
governmental proceeding by or against such Credit Party or any of its
Subsidiaries pending or, to its knowledge, threatened, which could reasonably be
expected (in light of reserves, and total shareholders' equity of such Credit
Party and after taking into account the nature of such Credit Party's business
and activities) to have a Material Adverse Effect if adversely determined.

         3.05. No Adverse Changes. Since November 30, 1997, there has been no
occurrence or event which has had a Material Adverse Effect.

         3.06. No Conflicting Laws or Agreements; Consents and Approvals. (a)
Neither the execution and delivery of this Agreement or any other Loan Document,
the consummation of the transactions herein or therein contemplated nor
compliance with the terms and provisions hereof or thereof will conflict with or
result in a breach of any of the terms, conditions or provisions of the articles
of incorporation or by-laws of such Credit Party or of any applicable Law or of
any material agreement or instrument to which such Credit Party is a party or by
which it is bound or to which it is subject, or constitute a default thereunder
or result in the creation or imposition of any Lien of any nature whatsoever
upon any of the property of such Credit Party pursuant to the terms of any such
agreement or instrument.

action by, and no registration, qualification, designation, declaration or
filing with, any Official Body is or will be necessary or advisable in
connection with (i) execution and delivery of this Agreement or any other Loan
Document, (ii) the consummation of the transactions herein or therein
contemplated, or (iii) the performance of or compliance with the terms and
conditions hereof or thereof.

         3.07. Execution and Binding Effect. This Agreement has been duly and
validly executed and delivered by such Credit Party. This Agreement constitutes,
and the Note when duly executed and delivered by such Credit Party pursuant to
the provisions hereof will constitute, legal, valid and binding obligations of
such Credit Party enforceable in accordance with the terms thereof except, as to
the enforcement of remedies, for limitations imposed by (i) bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement of creditors' rights generally (excluding Laws with respect to
fraudulent conveyance), (ii) Laws limiting the right of specific performance or
(iii) general principles of equity.

         3.08. Taxes. All tax returns required to be filed by such Credit Party
have been properly prepared, executed and filed. All taxes, assessments, fees
and other governmental charges upon such Credit Party or upon its properties,
income or sales which are due and payable have been paid. The reserves and

         3.09. Use of Proceeds. The Borrower will use the proceeds from any
borrowing hereunder for general corporate purposes (which may include
acquisitions). The Borrower will make no borrowing hereunder for the purpose of
buying or carrying any "margin stock" as such term is used in Regulation U of
the Board of Governors of the Federal Reserve System in violation of such
regulation. The Borrower is not engaged in the business of extending credit to
others for the purposes of buying or carrying any "margin stock."

         3.10. Permits, Licenses and Rights. Such Credit Party and each
Subsidiary of such Credit Party own or possess all the patents, trademarks,
service marks, trade names, copyrights, licenses, franchises, permits and rights
with respect to the foregoing necessary to own and operate their respective
properties and to carry on their respective businesses as presently conducted
and presently planned to be conducted without, to the best knowledge of such
Credit Party, conflict with the rights of others.

         3.11. Accurate and Complete Disclosure. All information provided by or
on behalf of such Credit Party to Lender pursuant to or in connection with the
Loan Documents and the transactions contemplated thereby is true and accurate in
all material respects on the date such information is dated (or, if not dated,
on the date such information was received by Lender) and such information, taken
as a whole, which was provided on or prior to the time this representation is
made or remade, does not, to the best knowledge of such Credit Party, omit to
state any material fact necessary to make such information not misleading at
such time in light of the circumstances in which it was provided.

         3.12. Absence of Violations. Such Credit Party and each Affiliate of
such Credit Party is not in violation of a any charter document, corporate
minute or resolution, any instrument or agreement, in each case binding on it or
affecting its property, or any Law, in a manner which could have a Materially
Adverse Effect.

         3.13. Environmental Matters. Such Credit Party and each of its
Subsidiaries is and has been in full compliance with all applicable

that are necessary or desirable for the ownership and operation of their
respective properties, facilities and businesses as presently owned and operated
and as presently proposed to be owned and operated.

         3.14. Not an Investment Company. Such Credit Party is not an Investment
Company required to be registered under the Investment Company Act of 1940.

         (a) Proceedings and Incumbency. There shall have been delivered to
Lender a certificate with respect to each Credit Party in form and substance
satisfactory to Lender dated the Closing Date and signed on behalf of such
Credit Party by the Secretary or an Assistant Secretary of such Credit Party,
certifying as to: (a) true copies of all corporate action taken by such Credit
Party relative to this Agreement, and the other Loan Documents applicable to it,
including but not limited to that described in Section 3.02 hereof and (b) the
names, true signatures and incumbency of the officer or officers of such Credit
Party authorized to execute and deliver this Agreement and the other Loan

unless and until a later certificate revising the prior certificate has been

         (b) Organizational Documents. There shall have been delivered to Lender
(i) certified copies of the articles of incorporation and by-laws for each
Credit Party, (ii) a certificate of good standing for each

<PAGE>
 
Credit Party certified by the appropriate Official Body and (iii) a certificate
of good standing certified by the appropriate Official Body.

         (c) Opinions of Counsel. There shall have been delivered to Lender
written opinions addressed to Lender, dated the Closing Date, of Cahill Gordon &
Reindel, Conyers, Dill & Pearman and Paul S. Giordano, Esq., respectively, the

shall be satisfactory to Lender, and Lender shall have received all such
counterpart originals or certified or other copies of the Loan Documents and

form and substance satisfactory to it, as Lender has reasonably requested.

         (e) Fees and Expenses. The Borrower shall have paid all fees and other
compensation to be paid by it hereunder on or prior to the Closing Date.

         (f) Representations and Warranties. The representations and warranties
contained in Article III hereof shall be true on and as of the Closing Date with

         (h) Funding Agreement. A funding agreement shall have been entered into
between the Lender and Mellon with respect to the transactions contemplated by

         4.02. Borrowings. The obligations of Lender to make any Loan hereunder

of its obligations to be performed hereunder on or before the date of such Loans
and to the satisfaction of the following further conditions:

         (a) Representations and Warranties; Events of Termination and Unmatured
Events. The representations and warranties contained in Article III hereof shall
be true on and as of the date of each Loan hereunder with the same effect as

stated to relate only to a prior date), and on the date of each Loan hereunder
no Event of Termination and no Unmatured Event shall have occurred and be
continuing or exist or shall occur or exist after giving effect to the Loans to
be made on such date. Failure of Lender to receive notice from the Borrower to
the contrary before any Loan is made or deemed made hereunder shall constitute a
representation and warranty that: (i) the representations and warranties
contained in Article III hereof are true and correct on and as of the date of
such Loan with the same effect as though made on and as of such date (except to
the extent they are expressly stated to relate only to a prior date) and (ii) on
the date of such Loan no Event of Termination or Unmatured Event has occurred
and is continuing or exists or will occur or exist after giving effect to such
Loan.

         (b) Commitment. The fact that, immediately after such Borrowing, the
aggregate outstanding principal amount of the Loans will not exceed the
aggregate amount of the Commitment.

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

         Each Credit Party hereby covenants to the Lender as follows:

         5.01. Reporting and Information Requirements. Such Credit Party shall

second and third quarterly accounting periods in each fiscal year of such Credit
Party, copies of the unaudited consolidated and consolidating balance sheets of

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

                                   GUARANTEE
                                   ---------

         8.01. The Guarantee. Each of the Guarantors guarantee to the Lender as
hereinafter provided the prompt payment of the Obligations of the Borrower (the
"Guaranteed Obligations") in full when due

                                       21
<PAGE>
 
(whether at stated maturity, by acceleration, or otherwise) strictly in
accordance with the terms thereof. Each Guarantor hereby further agrees that if
any of the Guaranteed Obligations are not paid in full when due (whether at
stated maturity, by acceleration, or otherwise), the Guarantor will promptly pay
the same, without any demand or notice whatsoever (except as expressly provided
herein), and that in the case of any extension of time of payment or renewal of
any of the Guaranteed Obligations, the same will be promptly paid in full when
due (whether at extended maturity, by acceleration or otherwise) in accordance
with the terms of such extension or renewal.

Notwithstanding any provision to the contrary contained herein or in any other
of the Loan Documents, to the extent the obligations of either Guarantor shall
be adjudicated to be invalid or unenforceable for any reason (including, without
limitation, because of any applicable law, including the insolvency laws,
relating to fraudulent conveyances or transfers) then the obligations of such
Guarantor hereunder automatically shall be limited to the maximum amount that is
permissible under applicable law.

         8.02. Obligations Unconditional. The obligations of each Guarantor
under this Article are absolute and unconditional (to the fullest extent
permitted by applicable law), irrespective of the value, genuineness, validity,
regularity or enforceability of any of the Loan Documents, or any other
agreement or instrument referred to therein, or any substitution, release or
exchange of any other guarantee of or security for any of the Guaranteed
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Article that the obligations of each Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.
Each Guarantor agrees that such Guarantor shall have no right of subrogation,
indemnity, reimbursement or contribution against the Borrower for amounts paid
under his Guarantee until such time as the Lender has been paid in full, the
Commitment under the Credit Agreement has been terminated and no Person or
Official Body shall have any right to request any return or reimbursement of
funds from the Lender in connection with monies received under the Loan
Documents. Without limiting the generality of the foregoing, it is agreed that,
to the fullest extent permitted by applicable law, the occurrence of any one or
more of the following shall not alter or impair the liability of either
Guarantor hereunder which shall remain absolute and unconditional as described
above:

                  (i) at any time or from time to time, without notice to the
         Guarantors, the time for any performance of or compliance with any of
         the Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (ii) any of the acts mentioned in any of the provisions of any
         of the Loan Documents, or any other agreement or instrument referred to
         in the Loan Documents shall be done or omitted;

                  (iii) the maturity of any of the Guaranteed Obligations shall
         be accelerated, or any of the Guaranteed Obligations shall be modified,
         supplemented or amended in any respect, or any right under any of the
         Loan Documents, or any other agreement or instrument referred to in the
         Loan Documents shall be waived or any other guarantee of any of the
         Guaranteed Obligations or any security therefor shall be released or
         exchanged in whole or in part or otherwise dealt with;

                  (iv) any Lien granted to, or in favor of, the Lender as
         security for any of the Guaranteed Obligations shall be void or
         violable, or shall fail to attach or be perfected; or

                  (v) any of the Guaranteed Obligations shall be determined to
         be void or voidable (including, without limitation, for the benefit of
         any creditor of either Guarantor) or shall be subordinated to the
         claims of any Person (including, without limitation, any creditor of
         either Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever (except notices expressly required hereunder), and

                                       22
<PAGE>
 
any requirement that the Lender exhaust any right, power or remedy or proceed
against any Person under any of the Loan Documents, or any other agreement or
instrument referred to in the Loan Documents, or against any other Person under
any other guarantee of, or security for, any of the Guaranteed Obligations.

         8.03. Reinstatement. The obligations of the Guarantors under this
Article shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of any Person in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy, receivership, or reorganization or otherwise, and each Guarantor
agrees that it will indemnify the Lender on demand for all reasonable
out-of-pocket costs and expenses (including, without limitation, reasonable fees
and expenses of counsel) incurred by the Lender in connection with such
rescission or restoration, including any such reasonable costs and expenses
incurred in defending against any claim alleging that such payment constituted a
preference, fraudulent transfer or similar payment under any bankruptcy,
insolvency, receivership, reorganization or similar law.

         8.04. Remedies. Each Guarantor agrees that, to the fullest extent
permitted by applicable law, as between such Guarantor, on the one hand, and the
Lender, on the other hand, the Guaranteed Obligations may be declared to be
forthwith due and payable as provided in Section 7.01 hereof (and shall be
deemed to have become automatically due and payable in the circumstances
provided in said Section 7.01) for purposes of Section 8.01 hereof
notwithstanding any stay, injunction or other prohibition preventing such
declaration (or preventing the Guaranteed Obligations from becoming
automatically due and payable) as to any other Person and that, in the event of
such declaration (or Guaranteed Obligations being deemed to have become
automatically due and payable), the Guaranteed Obligations (whether or not due
and payable by any other Person) shall forthwith become due and payable by such
Guarantor for purposes of said Section 8.01.

         8.05.  Continuing Guarantee.  The guarantee in this Article is a
continuing guarantee, and shall apply to all of the Guaranteed Obligations
whenever arising.

         8.06. No Restrictions. Except for restrictions under the Loan
Documents, neither Guarantor shall be or become subject to any restriction of
any nature (whether arising by operation of Law, by agreement, by its articles
of incorporation, by-laws or other constituent documents of such Guarantor, or
otherwise) on the right of such Guarantor from time to time to (x) pay any
indebtedness, obligations or liabilities from time to time owed to the Borrower,
or (y) make loans or advances to the Borrower, or (z) transfer any of its
properties or assets to the Borrower.

position and rights hereunder and under the Note and any other Loan Document to

or consent under or in respect of, this Agreement, the Note and the other Loan
Documents, and (d) pay, indemnify, and hold the Lender harmless from and against

foregoing, collectively, the "indemnified liabilities"), provided that the
Borrower shall not have any obligation hereunder to the Lender with respect to
indemnified liabilities arising from the gross negligence or willful misconduct
of the Lender. Without limitation of the generality of this Section 9.04(d), the
Borrower shall pay on demand to the Lender any and all amounts necessary to
indemnify the Lender from and against any and all indemnified liabilities
relating to or resulting from any of the following:

                  (i) reliance on any representation or warranty made or deemed
         made by the Borrower (or any of its officers) under or in connection
         with this Agreement, any Loan Document, any Loan Request or any other
         information or report delivered by the Borrower pursuant hereto, which,
         in any such case, shall have been false or incorrect in any material
         respect when made or deemed made or delivered, except to the extent it
         specifically relates to an earlier date:

                  (ii) the failure by the Borrower to comply with any term,
         provision or covenant contained in this Agreement or any Loan Document.

The agreements in this subsection shall survive repayment of the Loans, the Note
and all other amounts payable hereunder. Notwithstanding anything in this
Section 9.04 to the contrary, the Borrower shall not

                                       24
<PAGE>
 
have any obligation hereunder to the Lender with respect to indemnified
liabilities arising from the gross negligence or willful misconduct of the
Lender.

         9.05.  Successors and Assigns; Participations.
                --------------------------------------

         (a) This Agreement shall be binding upon and inure to the benefit of
the Borrower, the Lender, the Guarantors and all future holders of the Note and
their respective successors and assigns, except that neither the Borrower nor
any Guarantor may assign or transfer any of its rights or obligations under this
Agreement without the prior consent of the Lender, and the Lender may not assign
or transfer any of its rights or obligations under this Agreement without the
prior consent of the Borrower (which consent shall not be unreasonably
withheld). The parties to this Agreement acknowledge that the Lender has
assigned and shall be permitted to continue to assign (without consent) to the
Collateral Agent, as collateral agent for the benefit of the holders of any debt
instruments issued by the Lender, its rights under this Agreement and the other
Loan Documents (including its rights in the Collateral under the Pledge
Agreement).

         (b) The Borrower and the Lender agree that the Lender may, from time to
time, with the prior consent of the Borrower (which consent shall not be
unreasonably withheld), sell a portion of the Lender's obligation to make Loans
hereunder and of the Lender's rights hereunder and under the Loans and the Note,
or grant participations herein and in the Loans and the Note. Any such assignee
or participant may have the same rights as the Lender in respect of the rights
granted to the Lender hereunder. In such connection, it is agreed that the
Lender shall not be responsible for a failure by any such assignee or
participant, and that each such assignee or participant shall not be responsible
for a failure by the Lender (or another such assignee or participant), to make
or fund, as the case may be, its pro rata portion of any Loan.

         (c) Every participant or assignee of the Lender shall provide the
Borrower (A) prior to becoming a participant or assignee (i) if the participant
or assignee is incorporated or established under the laws of a jurisdiction
outside of the United States, two duly completed copies of the United States
Internal Revenue Form 4224 or 1001 (or, if the assignee or participant is not a
bank, Form W-8) or successor applicable or required forms, in each case
entitling the participant or assignee to receive payments under this Agreement
without deduction or withholding of any United States Federal income taxes and
demonstrating the participant's or assignee's exemption from backup withholding
tax, (ii) a duly completed copy of the Internal Revenue Service Form W-8 or W-9
or successor applicable or required forms, and (iii) such other forms and
information as may be reasonably required to confirm the availability of any
applicable exemption from United States Federal, state or local withholding
taxes, and (B) to the extent possible, each potential participant or assignee
must also agree to provide the Borrower on or before the date that any such form
expires or becomes obsolete, or upon the occurrence of any event requiring an
amendment, resubmission or change in the most recent form previously delivered
by it, and such extensions or renewals as may be reasonably requested by the
Borrower. Notwithstanding any provision of this Agreement to the contrary, the
Borrower shall be entitled to withhold or cause withholding, and no amount shall
be payable under Section 2.8, to the extent such amount would otherwise be
payable as the result of such participant's or assignee's failure to deliver the
forms required by this paragraph (c) on a timely basis.

         (d) The Lender shall not grant to any assignee or participant the right
to consent to any amendment or waiver entered into in accordance with subsection
9.01 except for any such amendment or waiver which would reduce the amount or
extend the due date of any principal of or interest on the Note.

         9.06. Set-Off. In case any one or more of the Events of Termination
described in Article VII hereof shall occur, the holder of the Note shall have
the right, in addition to all other rights and remedies available to it, to
set-off against the unpaid balance of the Note any debt owing by such holder to
the Borrower, including without limitation any funds in any deposit account
maintained by the Borrower with such holder, and such holder shall have and
there is hereby created in favor of such holder a security interest in all
deposit accounts maintained by the Borrower with such holder. Any sums obtained
by the holder of the Note issued hereunder by way of counterclaim, set-off,
banker's lien or other lien for application upon the Note shall be shared pro
rata with the holders of an interest in the Note or this

                                       25
<PAGE>
 
Agreement. Nothing in this Agreement shall be deemed any waiver or prohibition
of any right of banker's lien or set-off under applicable Law.

         9.07. Counterparts. This Agreement may be executed by one or more of
the parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument.

         9.08. Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         9.09. Integration. This Agreement represents the agreement of the
Borrower and the Lender with respect to the subject matter hereof, and there are
no promises, undertakings, representations or warranties by Lender relative to
the subject matter hereof not expressly set forth or referred to herein or in
the other Loan Documents.

         9.10. GOVERNING LAW. THIS AGREEMENT AND THE NOTE AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTE SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE
COMMONWEALTH OF PENNSYLVANIA.

COMMONWEALTH OF PENNSYLVANIA AND THE STATE OF NEW YORK, THE COURTS OF THE UNITED
STATES OF AMERICA FOR THE WESTERN DISTRICT OF PENNSYLVANIA AND THE SOUTHERN

         (b) CONSENTS THAT ANY SUCH ACTION OR PROCEEDING MAY BE BROUGHT IN SUCH
COURTS AND WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE
OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR
PROCEEDING WAS BROUGHT IN AN INCONVENIENT COURT AND AGREES NOT TO PLEAD OR CLAIM
THE SAME;

         (c) AGREES THAT SERVICE OF PROCESS IN ANY SUCH ACTION OR PROCEEDING MAY
BE EFFECTED BY MAILING A COPY THEREOF BY REGISTERED OR CERTIFIED MAIL (OR ANY
SUBSTANTIALLY SIMILAR FORM OF MAIL), POSTAGE PREPAID, TO ITS ADDRESS AS PROVIDED
IN SECTION 9.02 OR AT SUCH OTHER ADDRESS OF WHICH ALL OF THE OTHER PARTIES
HERETO SHALL HAVE BEEN NOTIFIED PURSUANT THERETO; AND

         (d) AGREES THAT NOTHING HEREIN SHALL AFFECT THE RIGHT TO EFFECT SERVICE
OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT TO SUE
IN ANY OTHER JURISDICTION.

         9.12.  Acknowledgments.  The Borrower hereby acknowledges that:

                                       26
<PAGE>
 
         (a) it has been advised by counsel in the negotiation, execution and
delivery of this Agreement, the Note and the other Loan Documents;

         (b) the Lender has no fiduciary relationship to the Borrower, and the
relationship between the Lender and the Borrower is solely that of debtor and
creditor; and

         (c) no joint venture exists between the Borrower and the Lender.

         9.13. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY LEGAL ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT OR THE NOTE OR ANY OTHER LOAN DOCUMENT AND
FOR ANY COUNTERCLAIM THEREIN.

         9.14. No Bankruptcy Petition Against Lender. The Borrower covenants and
agrees that it will not institute against, or join any other Person in
instituting against, the Lender any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings, or other proceedings under any federal or
state bankruptcy or similar law.

         9.15. No Recourse. The obligations of the Lender under this Agreement
are solely the corporate obligations of the Lender. No recourse shall be had for
the payment of any amount owing in respect to this Agreement or for the payment
of any fee hereunder or for any other obligation or claim arising out of or
based upon this Agreement against any stockholder, employee, officer, director
or incorporator of the Lender or against Mellon or any stockholder, employee,
officer, director, incorporator or affiliate thereof.

         9.16. Holidays. Unless otherwise specified herein, whenever any payment
or action to be made or taken hereunder or under the Note shall be stated to be
due on a Saturday, Sunday or public holiday under the laws of the Commonwealth
of Pennsylvania or Bermuda, such payment or action shall be made or taken on the
next succeeding Business Day and such extension of time shall in such case be
included in computing interest, if any, in connection with such payment or
action.

         9.17. Judgment Currency. In the event of a judgment or order being
rendered by any court or tribunal for the payment of any amounts owing to the
Lender under this Agreement or any other Loan Document or for the payment of
damages in respect of any breach of this Agreement or any other Loan Document or
under or in respect of a judgment or order of another court or tribunal for the
payment of such amounts or damages, such judgment or order being expressed in a
currency (the "Judgment Currency") other than Dollars the party against whom the
judgment or order is made shall indemnify and hold the Lender harmless against
any deficiency in terms of Dollars in the amounts received by the Lender arising
or resulting from any variations as between (i) the exchange rate at which
Dollars are converted into the Judgment Currency for the purposes of such
judgment or order and (ii) the exchange rate at which the Lender is able to
purchase Dollars with the amount of the Judgment Currency actually received by
the Lender on the date of such receipt. The indemnity in this section shall
constitute a separate and independent obligation from the other obligations of
the Borrower hereunder and shall apply irrespective of any indulgence granted by
the Lender.

         9.18. Records. The unpaid principal amount of the Loans owing to the
Lender, the unpaid interest accrued thereon, the interest rate or rates
applicable to such unpaid principal amount, the duration of such applicability,
the Lender's Commitment and the accrued and unpaid Facility Fees and Program
Fees shall at all times be ascertained from the records of the Lender, which
shall be conclusive absent manifest error.

         9.19. Confidentiality. The Lender agrees to keep confidential any
information relating to the Borrower received by it pursuant to or in connection
with this Agreement which is (a) information which the Lender reasonably expect
that the Borrower would want to keep confidential or (b) information which is
clearly marked "CONFIDENTIAL"; provided, however, that this Section 9.19 shall
not be construed to prevent the Lender from disclosing such information (i) to
any affiliate that shall agree in writing for the benefit of the Borrower to be
bound by this obligation of confidentiality, (ii) upon the order of any court or

                                       27
<PAGE>
 
administrative agency of competent jurisdiction, (iii) upon the request or
demand of any regulatory agency or authority having jurisdiction over the Lender
which request or demand has the force of Law or is made by a bank regulatory
agency, (iv) that has been publicly disclosed, other than from a breach of this
provision by the Lender, (v) that has been obtained from any person that is
neither a party to this Agreement nor an affiliate of any such party, but only
to the extent that the Lender does not know or have reason to know that such
disclosure violates a confidentiality agreement between such person and the
Borrower (vi) in connection with the exercise of any right or remedy hereunder
or under any other Loan Document, (vii) as expressly contemplated by this
Agreement or any other Loan Document, (viii) to any prospective purchaser of all
or any part of the interest of the Lender which shall agree in writing for the
benefit of the Borrower to be bound by the obligation of confidentiality in this
Agreement or the other Loan Documents if such prospective purchaser is a
financial institution or has been consented to by the Borrower, which consent
will not be withheld if such purchaser is not a competitor of the Borrower or an
affiliate of a competitor of the Borrower or (ix) to its liquidity or credit
providers under the Funding Agreement, which agrees in writing to maintain the
confidentiality of such information in accordance with this Section 9.19, or a
rating agency rating the securities of the Lender.

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

relying upon the representations and warranties herein set forth, the Issuing
Bank agrees to issue (or, in the case of Existing Letters of Credit, maintain

                                      10
<PAGE>

Available Amount.  Each Bank's "Letter of Credit Participating Interest

"evergreen" provision having substantially the effect set forth on Schedule
2.01(b) hereof, (ii) each Letter of Credit shall be denominated in Dollars or
Pounds and (iii) each Letter of Credit shall be payable only against sight
drafts (and not time drafts).

     (c)  Form of Letters of Credit.  The Issuing Bank shall have no obligation
          -------------------------                                            
to issue any letter of credit which is unsatisfactory in form, substance or
beneficiary to the Issuing Bank in the exercise of its reasonable judgment
consistent with its customary practice.  The Issuing Bank may not object to a
letter of credit on account of the fact that it may be presented for drawing at
the Issuing Bank's branch in London, England (or, if the Issuing Bank no longer
maintains such a branch at the time of issuance of a Letter of Credit, at such
other location in London, England as may be commercially reasonable).  It is
contemplated that one or more Letters of Credit which are issued for the account
of X.L. Insurance may be stated to be issued for the account of Venton
Underwriting Limited, a Bermuda corporation in which X.L. Insurance has an
indirect ownership interest provided, that, notwithstanding the fact that the
name of X.L. Insurance may not appear on the face of any such Letter of Credit,
X.L. Insurance shall be the Account Party with respect to such Letter of Credit
and shall have all Letter of Credit Reimbursement Obligations and other
obligations hereunder with respect thereto.

     (d)  Letter of Credit Fee.  Each Account Party shall pay or cause to be
          --------------------                                              
paid to the Agent for the account of each Bank, in accordance with its Letter of
Credit Participating Interest Commitment Percentage , a fee (the "Letter of
Credit Fee") for Letters of Credit (based on a year of 360 days and actual days
elapsed), for each Letter of Credit issued for the account of such Account Party
for each day from and including the date of issuance thereof to and including
the date of expiration or termination thereof, on the Letter of Credit Undrawn
Availability on such day at a rate per annum equal to 0.15% for each Level Five
Day, 0.165% for each Level Four Day, 0.18% for each Level Three Day, 0.23% for
each Level Two Day and 0.28% for each Level One Day.  Such Letter of Credit Fee
shall be due and payable for the preceding period for which such fee has not
been paid on each of the following dates: (i) each Regular Payment Date, (ii)
the date of each drawing on such Letter of Credit, and (iii) the date of
expiration or termination of such Letter of Credit.  If any Letter of Credit Fee
payment is made on a day which is not a Valuation Date, the amount of such
Letter of Credit Fee attributable to the period from the preceding Valuation
Date until such day shall be determined by reference to the rate applicable on
such preceding Valuation Date, subject to retroactive adjustment on the next
succeeding Valuation Date.  The Agent shall provide to the Grantor on a monthly
basis a certificate, showing in reasonable detail (with reference to the
valuation report as of the last business day of the applicable month provided by
the Custodian to the Agent pursuant to the Custodian's Acknowledgment (as
defined in the Pledge Agreement)) the Agent's calculation of the Letter of
Credit Fee.

     (e)  Purpose of Letters of Credit.  The Account Parties agree that each
          ----------------------------                                      
Letter of Credit shall be used by the Account Party for whom it is issued as a
standby letter of credit, to provide credit enhancement for contract performance
guarantees or for similar bonding requirements, all in the ordinary course of
business of such Account Party. The provisions of this Section 2.01(e) represent

                                      11
<PAGE>
 
only an obligation of the Account Parties to the Issuing Bank and the Banks; the
Issuing Bank shall have no obligation to the Banks to ascertain the purpose of
any Letter of Credit, and, without limiting the generality of the provisions of
Section 2.04(b) hereof, the rights and obligations of the Banks and the Issuing
Bank among themselves shall not be impaired or affected by a breach of this
Section 2.01(e).

     (f)  Administration Fees.  Each Account Party shall pay to the Agent, for
          -------------------                                                 
the sole account of the Issuing Bank, such other administration, maintenance,
amendment, drawing and negotiation fees as are customarily charged by the
Issuing Bank to its customers generally at the time in question (a list of which
customary charges as of the date of this Agreement has been provided by the
Issuing Bank to X.L. Insurance)  or are otherwise agreed between the Issuing
Bank and the Account Parties.

     2.02.  Commitment Fee; Reduction of the Committed Amounts.
            -------------------------------------------------- 

     (a)  Commitment Fee.  X.L. Insurance agrees to pay to the Agent for the
          --------------                                                    
account of each Bank a commitment fee (the "Commitment Fee") for each day during
the period from the Closing Date to and including the Expiration Date calculated
(based on a year of 360 days and actual days elapsed) at a per annum rate equal
to 0.05% payable on the unused portion of such Bank's Letter of Credit
Participating Interest Committed Amount in effect on such day.  Such fee shall
be payable on each Regular Payment Date and on the Expiration Date for the
preceding period for which such fee has not been paid.

     (b)  Reduction of the Committed Amounts.  X.L. Insurance may at any time or
          ----------------------------------                                    
from time to time reduce Pro Rata the Letter of Credit Participating Interest
Committed Amounts of the Banks to an aggregate amount (which may be zero) not
less than the Letter of Credit Exposure.  Any reduction of the Letter of Credit
Participating Interest Committed Amounts shall be in an aggregate minimum amount
of $25,000,000 and in an amount which is an integral multiple of $5,000,000.
Reduction of the Letter of Credit Participating Interest Committed Amounts shall
be made by providing not less than five Business Days' notice (which notice
shall be irrevocable) to such effect to the Agent.  After the date specified in
such notice, the Commitment Fee shall be calculated upon the Letter of Credit
Participating Interest Committed Amounts as so reduced.

     2.03.  Procedure for Issuance and Amendment of Letters of Credit.
            --------------------------------------------------------- 

     (a)  Request for Issuance.  An Account Party may from time to time request,
          --------------------                                                  
upon at least three Business Days' notice, the Issuing Bank to issue a Letter of
Credit by:

          (i)  delivering to the Issuing Bank and the Agent a written request to
     such effect, specifying the date on which such Letter of Credit is to be
     issued, the expiration date thereof, and the Stated Amount thereof, and

         (ii)  delivering to the Issuing Bank a completed application, in the
     form annexed hereto as Exhibit F, or in such other form as is from time to
     time be required by the Issuing Bank in accordance with its customary
     practice with respect to its customers generally (the "Letter of Credit
     Application"), together with such other certificates, documents and other
     papers as are specified in such application.

Upon receiving any such notice, the Issuing Bank shall promptly notify the Agent
(by telephone or otherwise), and furnish  the Agent with the proposed form of
Letter of Credit to be issued.  The Agent shall, promptly upon receiving such
notice, notify the Banks of such proposed Letter of Credit (which notice shall
specify the Stated Amount and term of such proposed Letter of Credit), and shall
determine, as of the close of business on the Business Day before such proposed
issuance, whether such proposed Letter of Credit complies with the limitations
set forth in Section 2.01 hereof. If  such limitations set forth in Section 2.01
are not satisfied or if the Required Banks have given notice to the 

                                      12
<PAGE>
 
Agent to cease issuing Letters of Credit pursuant to Section 2.03(c)(ii) hereof,
the Agent shall notify the Issuing Bank (in writing or by telephone promptly
confirmed in writing) that the Issuing Bank is not authorized to issue such
Letter of Credit. If the Issuing Bank issues a Letter of Credit, it shall
deliver the original of such Letter of Credit to the beneficiary thereof or as
the Account Party shall otherwise direct, and shall promptly notify the Agent
thereof and furnish a copy thereof to the Agent.

     (b)  Request for Extension or Increase.  An Account Party may from time to
          ---------------------------------                                    
time request the Issuing Bank to extend the expiration date of an outstanding
Letter of Credit or increase (or, with the consent of the beneficiary, decrease)
the Stated Amount of or the amount available to be drawn on such Letter of
Credit.  Such extension or increase shall for all purposes hereunder be treated
as though such Account Party had requested issuance of a replacement Letter of
Credit (except only that the Issuing Bank may, if it elects, issue a notice of
extension or increase in lieu of issuing a new Letter of Credit in substitution
for the outstanding Letter of Credit).

     (c)  Limitations on Issuance, Extension and Amendment.
          ------------------------------------------------ 

          (i)  As between the Issuing Bank, on the one hand, and the Agent and
     the Banks, on the other hand, the Issuing Bank shall be justified and fully
     protected in issuing such Letter of Credit after receiving authorization
     from the Agent as provided in Section 2.03(a) hereof, notwithstanding any
     subsequent notices to the Issuing Bank, any knowledge of an Event of
     Default (unless the Issuing Bank shall have received a notice specifying
     that such Event of Default is an "Event of Default" under this Agreement)
     or Potential Default, any knowledge of failure of any condition specified
     in Section 4.02 hereof to be satisfied, any other knowledge of the Issuing
     Bank, or any other event, condition or circumstance whatsoever.  The
     Issuing Bank may amend, modify or supplement Letters of Credit or Letter of
     Credit Applications, or waive compliance with any condition of issuance or
     payment, without the consent of, and without liability to, the Agent or any
     Bank, provided that any such amendment, modification or supplement that
     extends the expiration date or increases the Stated Amount of or the amount
     available to be drawn on an outstanding Letter of Credit shall be subject
     to Section 2.01.

          (ii)  As between the Agent, on the one hand, and the Banks, on the
     other hand, the Agent shall not authorize issuance of any Letter of Credit
     if the Agent shall have received, at least two Business Days before
     authorizing such issuance, from the Required Banks an unrevoked written
     notice that any condition precedent set forth in Section 4.02 will not be
     satisfied as of the time of such issuance and expressly requesting that the
     Agent direct the Issuing Bank to cease to issue Letters of Credit.  Absent
     such notice, or unless the Agent determines that the applicable limitations
     set forth in Section 2.01 hereof are not satisfied, the Agent shall be
     justified and fully protected, as against the Banks, in authorizing the
     Issuing Bank to issue such Letter of Credit, notwithstanding any subsequent
     notices to the Agent, any knowledge of an Event of Default or Potential
     Default, any knowledge of failure of any condition specified in Section
     4.02 hereof to be satisfied, any other knowledge of the Agent, or any other
     event, condition or circumstance whatsoever.

     2.04.  Letter of Credit Participating Interests.
            ---------------------------------------- 

     (a)  Generally.  Concurrently with the issuance of each Letter of Credit,
          ---------                                                           
the Issuing Bank automatically shall be deemed, irrevocably and unconditionally,
to have sold, assigned, transferred and conveyed to each other Bank, and each
other Bank automatically shall be deemed, irrevocably and unconditionally,
severally to have purchased, acquired, accepted and assumed from the Issuing
Bank, without recourse to, or representation or warranty by, the Issuing Bank,
an undivided interest, in a proportion equal to such Bank's Pro Rata share, in
all of the Issuing Bank's rights and obligations in, to or under such Letter of
Credit, the related Letter of Credit Application, the Letter of Credit
Reimbursement Obligations, and all collateral, guarantees and other rights from
time to time directly 

                                      13
<PAGE>
 
or indirectly securing the foregoing (such interest of each Bank being referred
to herein as a "Letter of Credit Participating Interest", it being understood
that the Letter of Credit Participating Interest of the Issuing Bank is the
interest not otherwise attributable to the Letter of Credit Participating
Interests of the other Banks). Each Bank irrevocably and unconditionally agrees
to the immediately preceding sentence, such agreement being herein referred to
as such Bank's "Letter of Credit Participating Interest Commitment". Amounts
other than Letter of Credit Reimbursement Obligations and Letter of Credit Fees
payable from time to time under or in connection with a Letter of Credit or
Letter of Credit Application shall be for the sole account of the Issuing Bank.
On the date that any Purchasing Bank becomes a party to this Agreement in
accordance with Section 9.13(c) hereof, Letter of Credit Participating Interests
in all outstanding Letters of Credit held by the Bank from which such Purchasing
Bank acquired its interest hereunder shall be proportionately reallocated
between such Purchasing Bank and such transferor Bank (and, to the extent such
transferor Bank is the Issuing Bank, the Purchasing Bank shall be deemed to have
acquired a Letter of Credit Participating Interest from the Issuing Bank to such
extent).

     (b)  Maximum Amounts of Funding of Participations.
          -------------------------------------------- 

          (i)  This Section 2.04(b)(i) is applicable if the Conversion to
Tranche System has not occurred.  No Bank will be obligated to fund its Letter
of Credit Participating Interest Percentage of a drawing on a Letter of Credit
if such funding would cause the aggregate amount of outstanding unreimbursed
fundings by such Bank of drawings on Letters of Credit to exceed such Bank's
Letter of Credit Participating Interest Committed Amount, unless such excess
results from the fact, with respect to a drawing on a Letter of Credit
denominated in Pounds, that the Dollar Equivalent of one Pound is higher at the
time of such funding than it was at the time of issuance of such Letter of
Credit denominated in Pounds.

          (ii)  This Section 2.04(b)(ii) is applicable if the Conversion to
Tranche System has occurred. No Tranche 1 Bank, Tranche 2 Bank or Tranche X
Bank, as the case may be, will be obligated to fund its Letter of Credit
Participating Interest Percentage of a drawing on a Tranche 1 Letter of Credit,
Tranche 2 Letter of Credit or Tranche X Letter of Credit, as the case may be, if
such funding would cause the aggregate amount of outstanding unreimbursed
fundings by such Bank of drawings on Letters of Credit under such applicable
Tranche to exceed such Bank's Letter of Credit Participating Interest Committed
Amount under such applicable Tranche, unless such excess results from the fact,
with respect to a drawing on a Letter of Credit denominated in Pounds, that the
Dollar Equivalent Amount of one Pound is higher at the time of such funding than
it was at the time of issuance of such Letter of Credit denominated in Pounds.

     (c)  Obligations Absolute.  Notwithstanding any other provision hereof,
          --------------------                                              
each Bank hereby agrees that its obligation to participate in each Letter of
Credit issued in accordance herewith, its obligation to make the payments
specified in Section 2.05 hereof, and the right of the Issuing Bank to receive
such payments in the manner specified therein, are each absolute, irrevocable
and unconditional and shall not be affected by any event, condition or
circumstance whatever.  The failure of any Bank to make any such payment shall
not relieve any other Bank of its funding obligation hereunder on the date due,
but no Bank shall be responsible for the failure of any other Bank to meet its
funding obligations hereunder.

     2.05.  Letter of Credit Drawings and Reimbursements.
            -------------------------------------------- 

     (a)  Account Party's Reimbursement Obligation.  Each Account Party hereby
          -----------------------------------------                           
agrees to reimburse the Issuing Bank, by making payment to the Agent for the
account of the Issuing Bank in accordance with Section 2.11(a) hereof on the
date of each payment made by the Issuing Bank under any Letter of Credit issued
for such Account Party's account (or, if later, the date which is one Business
Day after notice of such payment or of the drawing giving rise to such payment
is given to X.L. Insurance), without, protest or demand, all of which are hereby
waived, and an action therefor 

                                      14
<PAGE>
 
shall immediately accrue. Each Account Party agrees that it will make such
payment to the Agent for the account of the Issuing Bank in the same currency as
the currency of the payment by the Issuing Bank under such Letter of Credit. To
the extent such payment is not timely made, such Account Party hereby agrees to
pay to the Agent, for the account of the Issuing Bank, on demand, interest on
any Letter of Credit Unreimbursed Draws for each day from and including the date
of such payment by the Issuing Bank until paid (before and after judgment) in
accordance with Section 2.11(a) hereof, at the rate per annum set forth in
Section 2.11(b) hereof.

     (b)  Payment by Banks on Account of Unreimbursed Draws.  If the Issuing
          -------------------------------------------------                 
Bank makes a payment under any Letter of Credit and is not reimbursed in full
therefor on such payment date in accordance with Section 2.05(a) hereof, the
Issuing Bank will promptly notify the Agent thereof (which notice may be by
telephone), and the Agent shall forthwith notify each Bank (which notice may be
by telephone promptly confirmed in writing) thereof.  No later than the Agent's
close of business on the date such notice is given (if notice is given by 2:00
o'clock P.M.) or 10:00 o'clock A.M. the following day (if notice is given after
2:00 o'clock P.M.) , each such Bank will pay to the Agent, for the account of
the Issuing Bank, in immediately available funds, an amount equal to such Bank's
Pro Rata share of the unreimbursed portion of such payment by the Issuing Bank,
provided such notice is given no later than 2:00 o'clock P.M., Pittsburgh time.
- --------                                                                        
Each Bank agrees that such payment to the Agent for the account of the Issuing
Bank shall be in the same currency as the currency of the payment by the Issuing
Bank under the Letter of Credit.  If and to the extent that any Bank fails to
make such payment to the Issuing Bank on such date, such Bank shall pay such
amount on demand, together with interest, for the Issuing Bank's own account,
for each day from and including the date of the Issuing Bank's payment to and
including the date of repayment to the Issuing Bank (before and after judgment)
at rate per annum for each day from and including the date of such payment by
the Issuing Bank to and including the second Business Day thereafter equal to
the Applicable Interest Rate.

     (c)  Distributions to Banks.  If, at any time, after there occurs a Letter
          ----------------------                                               
of Credit Unreimbursed Draw and the Issuing Bank has received from any Bank such
Bank's share of such Letter of Credit Unreimbursed Draw, and the Issuing Bank
receives any payment or makes any application of funds on account of the Letter
of Credit Reimbursement Obligation arising from such Letter of Credit
Unreimbursed Draw, the Issuing Bank will pay to the Agent, for the account of
such Bank , such Bank's Pro Rata share of such payment.

     (d)  Rescission.  If any amount received by the Issuing Bank on account of
          ----------                                                           
any Letter of Credit Reimbursement Obligation shall be avoided, rescinded or
otherwise returned or paid over by the Issuing Bank for any reason at any time,
whether before or after the termination of this Agreement (or the Issuing Bank
believes in good faith that such avoidance, rescission, return or payment is
required, whether or not such matter has been adjudicated), each such Bank will,
promptly upon notice from the Agent or the Issuing Bank, pay over to the Agent
for the account of the Issuing Bank its Pro Rata share of such amount, together
with its Pro Rata share of any interest or penalties payable with respect
thereto.

     2.06  Equalization.  If any Bank receives any payment or makes any
           ------------                                                
application on account of its Letter of Credit Participating Interest, such Bank
shall forthwith pay over to the Issuing Bank, in Dollars and in like kind of
funds received or applied by it the amount in excess of such Bank's ratable
share of the amount so received or applied.

     2.07.  Obligations Absolute.  The payment obligations of the Account
            --------------------                                         
Parties and of the Banks under Section 2.05 shall be unconditional and
irrevocable and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including, without limitation, the following
circumstances:

                                      15
<PAGE>
 
     (a)  any lack of validity or enforceability of this Agreement, any Letter
of Credit or any Transaction Document against an Account Party;

     (b)  the existence of any claim, set-off, defense or other right which any
Account Party, any Guarantor or any other Person may have at any time against
any beneficiary or transferee of any Letter of Credit (or any Persons for whom
any such beneficiary or transferee may be acting), the Issuing Bank, any Bank,
or any other Person, whether in connection with this Agreement, the transactions
contemplated hereby or any unrelated transaction;

     (c)  any draft, certificate, statement or other document presented under
any Letter of Credit proving to be forged,  fraudulent, invalid or insufficient
in any respect or any statement therein being untrue or inaccurate in any
respect;

     (d)  payment by the Issuing Bank under any Letter of Credit against
presentation of a draft or certificate which does not comply with the terms of
such Letter of Credit, or payment by the Issuing Bank under the Letter of Credit
in any other circumstances in which conditions to payment are not met, except
any such wrongful payment resulting solely from the gross negligence or willful
misconduct of the Issuing Bank; or

     (e)  any other event, condition or circumstance whatever, whether or not
similar to any of the foregoing, except if the same results solely from the
gross negligence or willful misconduct of the Issuing Bank.

Each Account Party bears the risk of, and neither the Issuing Bank, any of its
directors, officers, employees or agents, nor any Bank, shall be liable or
responsible for any of, the foregoing matters, the use which may be made of any
Letter of Credit, or acts or omissions of the beneficiary or any transferee in
connection therewith, except for such person's gross negligence or willful
misconduct.

     2.08.  Further Assurances.  Each Account Party and each Guarantor hereby
            ------------------                                               
agrees, from time to time, to do and perform any and all acts and to execute any
and all further instruments reasonably requested by the Issuing Bank more fully
to effect the purposes of this Agreement and the issuance of the Letters of
Credit hereunder.

     2.09.  Letter of Credit Applications.  The representations, warranties and
            -----------------------------                                      
covenants by the Account Parties under, and the rights and remedies of the
Issuing Bank under, the Continuing Letter of Credit Agreement and any Letter of
Credit Application relating to any Letter of Credit are in addition to, and not
in limitation or derogation of, representations, warranties and covenants by the
Account Parties under, and rights and remedies of the Issuing Bank and the Banks
under, this Agreement, the Transaction Documents, and applicable Law.  Each
Account Party acknowledges and agrees that all rights of the Issuing Bank under
any Letter of Credit Application shall inure to the benefit of each Bank to the
extent of its Letter of Credit Participating Interest Commitment Percentage as
fully as if such Bank was a party to such Letter of Credit Application.  In the
event of any inconsistency between the terms of this Agreement and any Letter of
Credit Application, this Agreement shall prevail.

     2.10.  Certain Provisions Relating to the Issuing Bank.
            ----------------------------------------------- 

     (a)  General.  The Issuing Bank shall have no duties or responsibilities
          -------                                                            
except those expressly set forth in this Agreement and the other Transaction
Documents, and no implied duties or responsibilities on the part of the Issuing
Bank shall be read into this Agreement or any Transaction Document or shall
otherwise exist.  The duties and responsibilities of the Issuing Bank to the
other Bank Parties under this Agreement and the other Transaction Documents
shall be mechanical and administrative in nature, and the Issuing Bank shall not
have a fiduciary relationship in respect of any Bank Party or any other Person.
The Issuing Bank shall not be liable for any action taken or omitted to be taken
by it under or in connection with this Agreement or any other Transaction
Document, unless 

                                      16
<PAGE>
 
caused by its own gross negligence or willful misconduct. The Issuing Bank shall
not be under any obligation to ascertain, inquire or give any notice relating to
(i) the performance or observance of any of the terms or conditions of this
Agreement or any other Transaction Document on the part of any Account Party,
(ii) the business, operations, condition (financial or otherwise) or prospects
of the Account Parties or any other Person, or (iii) the existence of any Event
of Default or Potential Default. The Issuing Bank shall not be under any
obligation, either initially or on a continuing basis, to provide the Agent or
any Bank with any notices, reports or information of any nature, whether in its
possession presently or hereafter, except for such notices, reports and other
information expressly required by this Agreement to be so furnished. The Issuing
Bank shall not be responsible for the execution, delivery, effectiveness,
enforceability, genuineness, validity or adequacy of this Agreement or any other
Transaction Document.

     (b)  Administration.  The Issuing Bank may rely upon any notice or other
          --------------                                                     
communication of any nature (written or oral, including but not limited to
telephone conversations, whether or not such notice or other communication is
made in a manner permitted or required by this Agreement or any Transaction
Document) purportedly made by or on behalf of the proper party or parties, and
the Issuing Bank shall not have any duty to verify the identity or authority of
any Person giving such notice or other communication.  The Issuing Bank may
consult with legal counsel (including, without limitation, in-house counsel for
the Issuing Bank or in-house or other counsel for the Account Parties),
independent public accountants and any other experts selected by it from time to
time, and the Issuing Bank shall not be liable for any action taken or omitted
to be taken in good faith in accordance with the advice of such counsel,
accountants or experts.  Whenever the Issuing Bank shall deem it necessary or
desirable that a matter be proved or established with respect to any Account
Party or Bank Party, such matter may be established by a certificate of such
Account Party or Bank Party, as the case may be, and the Issuing Bank may
conclusively rely upon such certificate.  The Issuing Bank shall not be deemed
to have any knowledge or notice of the occurrence of any Event of Default or
Potential Default unless the Issuing Bank has received notice from a Bank or any
Credit Party referring to this Agreement, describing such Event of Default or
Potential Default, and stating that such notice is a "notice of default".  If
the Issuing Bank receives such a notice, the Issuing Bank shall give prompt
notice thereof to the Agent.

     (c)  Indemnification of Issuing Bank by Banks.  Each Bank hereby agrees to
          ----------------------------------------                             
reimburse and indemnify the Issuing Bank and each of its directors, officers,
employees and agents (to the extent not reimbursed by the Account Parties and
without limitation of the obligations of the Account Parties to do so), Pro
Rata, from and against any and all amounts, losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs or
disbursements of any kind or nature (including, without limitation, the
reasonable fees and disbursements of counsel (other than in-house counsel) for
the Issuing Bank or such other Person in connection with any investigative,
administrative or judicial proceeding commenced or threatened, whether or not
the Issuing Bank or such other Person shall be designated a party thereto) that
may at any time be imposed on, incurred by or asserted against the Issuing Bank,
in its capacity as such, or such other Person, as a result of, or arising out
of, or in any way related to or by reason of, this Agreement, any other
Transaction Document, any transaction from time to time contemplated hereby or
thereby, or any transaction financed in whole or in part or directly or
indirectly with the proceeds of any Letter of Credit, provided, that no Bank
                                                      --------              
shall be liable for any portion of such amounts, losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs or
disbursements resulting from the gross negligence or willful misconduct of the
Issuing Bank or  such other Person, as finally determined by a court of
competent jurisdiction.

     (d)  Issuing Bank in its Individual Capacity.  With respect to its
          ---------------------------------------                      
Commitments and the Obligations owing to it, the Issuing Bank shall have the
same rights and powers under this Agreement and each other Transaction Document
as any other Bank and may exercise the same as though it were not the Issuing
Bank, and the terms "Banks," "holders of Notes" and like terms shall include the
Issuing Bank in its individual capacity as such.  The Issuing Bank and its
affiliates may, without liability to account, make loans to, accept deposits
from, acquire debt or equity interests in, act as 

                                      17
<PAGE>
 
trustee under indentures of, act as agent under other credit facilities for, and
engage in any other business with, any Credit Party and any stockholder,
subsidiary or affiliate of any Credit Party, as though the Issuing Bank were not
the Issuing Bank hereunder.

     2.11. Payments Generally; Interest and Interest on Overdue Amounts.
           ------------------------------------------------------------ 

     (a)  Payments Generally.  All payments to be made by an Account Party in
          ------------------                                                 
respect of fees, indemnity, expenses or other amounts due from such Account
Party hereunder or under any Transaction Document shall be payable in Dollars at
12:00 o'clock Noon, Pittsburgh time, on the day when due without presentment,
demand, protest or notice of any kind, all of which are hereby expressly waived,
and an action therefor shall immediately accrue, without setoff, counterclaim,
withholding or other deduction of any kind or nature.  Except for payments under
Sections 2.12, 2.13 and 9.04 hereof, such payments shall be made to the Agent at
its Office in Dollars in funds immediately available at such Office.  Payments
under Sections 2.12, 2.13 and 9.04 hereof shall be made to the applicable Bank
at such domestic account as it shall specify to the Account Parties from time to
time in funds immediately available at such account.  Any payment or prepayment
received by the Agent or such Bank after 12:00 o'clock Noon, Pittsburgh time, on
any day shall be deemed to have been received on the next succeeding Business
Day.  The Agent shall distribute to the Banks all such payments received by it
from an Account Party as promptly as practicable after receipt by the Agent.

     (b)  Interest and Interest on Overdue Amounts.  Interest on Letter of
          ----------------------------------------                        
Credit Reimbursement Obligations shall accrue at a rate per annum (based on a
year of 360 days and actual days elapsed) which for each day shall be equal to
the then-current Applicable Interest Rate beginning on the day that the related
Letter of Credit payment is made and shall be due and payable on the day that
the Letter of Credit Reimbursement Obligation is due and payable in accordance
with Section 2.05(a) hereof.  To the extent permitted by law, after there shall
have become due (by acceleration or otherwise) fees, indemnity, expenses or any
other amounts due from the Account Parties hereunder or under any other
Transaction Document, such amounts shall bear interest for each day until paid
(before and after judgment), payable on demand, at a rate per annum (in each
case based on a year of 360 days and actual days elapsed) which for each day
shall be equal to 2% above the then-current Applicable Interest Rate.  To the
extent permitted by law, interest accrued on any amount which has become due
hereunder or under any Transaction Document shall compound on a day-by-day
basis, and hence shall be added daily to the overdue amount to which such
interest relates.

     2.12.  Additional Compensation in Certain Circumstances.  If the
            ------------------------------------------------         
introduction of or any change in, or any change in the interpretation or
application of, any Law, regulation or guideline by any Official Body charged
with the interpretation or administration thereof or compliance with any request
or directive of any applicable Official Body (whether or not having the force of
law):

            (i) subjects any Bank to any tax or changes the basis of taxation
     with respect to this Agreement, the Letters of Credit or payments by the
     Account Parties of fees or other amounts due from the Account Parties
     hereunder or under the other Transaction Documents (except for taxes on the
     overall net income or overall gross receipts of such Bank imposed by the
     jurisdictions (federal, state and local) in which the Bank's principal
     office is located),

           (ii) imposes, modifies or deems applicable any reserve, special
     deposit or similar requirement against credits or commitments to extend
     credit extended by, assets (funded or contingent) of, deposits with or for
     the account of, other acquisitions of funds by, such Bank,

          (iii) imposes, modifies or deems applicable any capital adequacy or
     similar requirement (A) against assets (funded or contingent) of, or
     credits or commitments to extend credit extended by, any Bank or (B)
     otherwise applicable to the obligations of any Bank under this Agreement,
     or

                                      18
<PAGE>
 
          (iv)  imposes upon any Bank any other condition or expense with
     respect to this Agreement or the issuance of any Letter of Credit,

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Bank or, in the case of clause (iii) hereof, any Person controlling a Bank, with
respect to this Agreement or the issuance of any Letter of Credit (or, in the
case of any capital adequacy or similar requirement, to have the effect of
reducing the rate of return on such Bank's or controlling Person's capital,
taking into consideration such Bank's or controlling Person's policies with
respect to capital adequacy so long as such policies are reasonable in light of
prevailing market practice at the time) by an amount which such Bank deems to be
material, such Bank may from time to time notify the Account Parties of the
amount determined in good faith (using any averaging and attribution methods) by
such Bank (which determination shall be conclusive) to be necessary to
compensate such Bank for such increase, reduction or imposition.  Such amount
shall be due and payable by any applicable Account Party to such Bank five
Business Days after such notice is given, together with an amount equal to
interest on such amount from the date two Business Days after the date demanded
until such due date at the Prime Rate.  A certificate by such Bank as to the
amount due and payable under this Section 2.12 from time to time and the method
of calculating such amount shall be conclusive.  Each Bank agrees that it will
use good faith efforts to notify the Account Parties of the occurrence of any
event that would give rise to a payment under this Section 2.12; provided,
                                                                 -------- 
however that, so long as such notice is given within a reasonable period after
the occurrence of such event, any failure of such Bank to give any such notice
shall have no effect on the Account Parties' obligations hereunder.

     2.13.  Taxes.
            ----- 

     (a)  Payments Net of Taxes.  All payments made by the Account Parties under
          ---------------------                                                 
this Agreement or any other Transaction Document shall be made free and clear
of, and without reduction or withholding for or on account of, any present or
future income, stamp or other taxes, levies, imposts, duties, charges, fees,
deductions or withholdings, now or hereafter imposed, levied, collected,
withheld or assessed by any Official Body, and all liabilities with respect
thereto, excluding

          (i)  in the case of the Agent and each Bank, income or franchise taxes
     imposed on the Agent or such Bank by the jurisdiction under the laws of
     which the Agent or such Bank is organized or any political subdivision or
     taxing authority thereof or therein or as a result of a connection between
     such Bank and any jurisdiction other than a connection resulting solely
     from this Agreement and the transactions contemplated hereby, and

          (ii)  in the case of each Bank, income or franchise taxes imposed by
     any jurisdiction in which such Bank's lending offices which issue Letters
     of Credit are located or any political subdivision or taxing authority
     thereof or therein

(all such non-excluded taxes, levies, imposts, deductions, charges or
withholdings being hereinafter called "Taxes"), unless an Account Party is
required to withhold or deduct Taxes.  If any Taxes are required to be withheld
or deducted from any amounts payable to the Agent or any Bank under this
Agreement or any other Transaction Document, the applicable Account Party shall
pay the relevant amount of such Taxes and the amounts so payable to the Agent or
such Bank shall be increased to the extent necessary to yield to the Agent or
such Bank (after payment of all Taxes) interest or any such other amounts
payable hereunder at the rates or in the amounts specified in this Agreement and
the other Transaction Documents.  Whenever any Taxes are paid by an Account
Party with respect to payments made in connection with this Agreement or any
other Transaction Document, as promptly as possible thereafter, such Account
Party shall send to the Agent for its own account or for the account of such
Bank, as the case may be, a certified copy of an original official receipt
received by such Account Party showing payment thereof.  If the Agent or a Bank
determines in its sole discretion in good faith that it has received a refund in
respect of any Taxes as to which it has been indemnified by 

                                      19
<PAGE>
 
an Account Party, or with respect to which an Account Party has paid additional
amounts pursuant to this Section 2.13, the Agent or such Bank shall promptly
after the date of such receipt pay over the amount of such refund to such
Account Party (but only to the extent of indemnity payments made, or additional
amounts paid, by an Account Party under this Section 2.13 with respect to Taxes
giving rise to such refund and only to the extent that the Agent or such Bank
has determined that the amount of any such refund is directly attributable to
payments made under this Agreement), net of all reasonable expenses of the Agent
or such Bank (including additional Taxes attributable to such refund, as
determined by the Agent or such Bank) and without interest (other than interest,
if any, paid by the relevant Official Body with respect to such refund). An
Account Party receiving any such payment from the Agent or a Bank shall, upon
demand, pay to the Agent or such Bank any amount paid over to such Account Party
by the Agent or such Bank (plus penalties, interest or other charges) in the
event the Agent or such Bank is required to repay any portion of such refund to
such Official Body. Nothing in this Section 2.13(a) shall entitle an Account
Party to have access to the records of the Agent or any Bank, including, without
limitation, tax returns.

     (b)  Indemnity.  Each Account Party hereby indemnifies the Agent and each
          ---------                                                           
of the Banks for the full amount of all Taxes attributable to payments by or on
behalf of such Account Party hereunder or under any of the other Transaction
Documents, any Taxes paid by the Agent or such Bank, as the case may be, any
present or future claims, liabilities or losses with respect to or resulting
from any omission to pay or delay in paying any Taxes (including any incremental
Taxes, interest or penalties that may become payable by the Agent or such Bank
as a result of any failure to pay such Taxes, except by reason of unreasonable
delay by the Agent or Bank in notifying an Account Party or in making payment
after payment was received from an Account Party), whether or not such Taxes
were correctly or legally asserted.  Such indemnification shall be made within
30 days from the date such Bank or the Agent, as the case may be, makes written
demand therefor.

     (c)  Withholding and Backup Withholding.  Each Bank that is incorporated or
          ----------------------------------                                    
organized under the laws of any jurisdiction other than the United States or any
State thereof agrees that, on or prior to the date the first payment is due to
be made to it hereunder or under any other Transaction Document, it will furnish
to the Account Parties and the Agent

          (i)  two valid, duly completed copies of United States Internal
     Revenue Service Form 4224 or United States Internal Revenue Form 1001 or
     successor applicable form, as the case may be, certifying in each case that
     such Bank is entitled to receive payments under this Agreement and the
     other Transaction Documents without deduction or withholding of any United
     States federal income taxes and

         (ii)  a valid, duly completed Internal Revenue Service Form W-8 or W-9
     or successor applicable form, as the case may be, to establish an exemption
     from United States backup withholding tax.

Each Bank which so delivers to the Account Parties and the Agent a Form 1001 or
4224 and Form W-8 or W-9, or successor applicable forms, agrees to deliver to
the Account Parties and the Agent two further copies of the said Form 1001 or
4224 and Form W-8 or W-9, or successor applicable forms, or other manner of
certification, as the case may be, on or before the date that any such form
expires or becomes obsolete or otherwise is required to be resubmitted as a
condition to obtaining an exemption from withholding tax, or after the
occurrence of any event requiring a change in the most recent form previously
delivered by it, and such extensions or renewals thereof as may reasonably be
requested by the Account Parties and the Agent, certifying in the case of a Form
1001 or Form 4224 that such Bank is entitled to receive payments under this
Agreement or any other Transaction Document without deduction or withholding of
any United States federal income taxes, unless in any such cases an event
(including any changes in Law) has occurred prior to the date on which any such
delivery would otherwise be required which renders all such forms inapplicable
or which would prevent such Bank from duly completing and delivering any such
letter or form with respect to it and such Bank advises 

                                      20
<PAGE>
 
the Account Parties and the Agent that it is not capable of receiving payments
without any deduction or withholding of United States federal income tax, and in
the case of a Form W-8 or W-9, establishing an exemption from United States
backup withholding tax, in which case Section 2.13(a) and (b) shall apply to all
further payments.

     2.14.  Extensions of Expiration Date.  X.L. Insurance may, at its option,
            -----------------------------                                     
give the Agent and the Issuing Bank written notice (an "Extension Request") at
any time not more than ninety days, nor less than forty-five days, prior to the
Expiration Date in effect at such time (the "Current Expiration Date") of X.L.
Insurance's desire to extend the Expiration Date to a date which is not later
than 364 days after the Current Expiration Date.  The Agent shall promptly
inform the Banks of such Extension Request.  Each Bank which agrees to such
Extension Request shall deliver to the Agent its express written consent thereto
no later than thirty days prior to the Current Expiration Date.  No extension
shall become effective unless the express written consent thereto by the
Required Commitment Banks and the Issuing Bank is received by the Agent on or
before the thirtieth day prior to the Current Expiration Date.  If the Issuing
Bank and the Required Commitment Banks, but not all Commitment Banks, have
expressly consented in writing to such Extension Request by such thirtieth day,
then the Agent shall so notify X.L. Insurance and X.L. Insurance may, effective
as of the Current Expiration Date, take one or both of the following actions:
(i) replace any Commitment Bank which has not agreed to such Extension Request
(a "Nonextending Bank") with another commercial lending institution satisfactory
to the Issuing Bank (a "Replacement Bank") by giving notice of the name of such
Replacement Bank to the Agent and the Issuing Bank not later than five Business
Days prior to the then effective Expiration Date and (ii) elect to implement a
Conversion to Tranche System as contemplated by Section 2.15 hereof (or, if the
Conversion to Tranche System has previously been implemented, elect to implement
a Supplement to Tranche System as contemplated by Section 2.15 hereof).  In the
event that a Nonextending Bank is to be replaced by a Replacement Bank, such
Nonextending Bank shall, upon payment to it of all amounts owing to it on the
date of its replacement, assign all of its interests hereunder to such
Replacement Bank in accordance with the provisions of Section 9.13(c) hereof.
If the Issuing Bank and the Required Commitment Banks shall have consented to
such Extension Request, then, on the Current Expiration Date, the Expiration
Date shall be deemed to have been extended to, and shall be, the date specified
in such Extension Notice.  The Agent shall promptly after any such extension
advise the Banks of any changes in the Letter of Credit Participating Interest
Committed Amounts and the Letter of Credit Participating Interest Commitment
Percentages, as well as any changes effected by the election of the Conversion
to Tranche System or a Supplement to Tranche System.

          Commitment Banks, but not by all of the Commitment Banks, to classify

          in effect on such first Special Expiration Date.

               "Tranche 1 Letter of Credit Participating Interest Percentage"
          for each Tranche 1 Bank means such Bank's Letter of Credit

(unless the concept of good standing is not known to the law of the relevant
jurisdiction) in good standing under the laws of their respective jurisdictions
of incorporation and has the power and authority to own its properties and
assets, and to carry on its business as presently conducted and is qualified to
do business in those jurisdictions in which its ownership of property or the
nature of its business activities is such that failure to receive or retain such
qualification would have a Material Adverse Effect.  A list of such Credit
Party's Credit Subsidiaries setting forth their respective jurisdictions of
incorporation is set forth in Schedule 3.01 hereto.  Such Credit Party is not
subject to any Private Act, except, with respect to X.L. Insurance, the X.L.

            (a)  The Agent shall have no duties or responsibilities except those
     expressly set forth in this Agreement and the other Transaction Documents,

     read into this Agreement or any Transaction Document or shall otherwise
     exist.

            (b)  The duties and responsibilities of the Agent under this

     administrative in nature, and the Agent shall not have a fiduciary
     relationship in respect of any Bank.

            (c)  The Agent is and shall be solely the agent of the Banks.  The
     Agent does not assume, and shall not at any time be deemed to have, any
     relationship of agency or trust with or for, or any other duty or
     responsibility to, any other Person (except only for its relationship as
     agent for, and its express duties and responsibilities to, the Banks as
     provided in this Agreement and the other Transaction Documents).

            (d)  The Agent shall be under no obligation to take any action
     hereunder or under any other Transaction Document if the Agent believes in
     good faith that taking such action may conflict with any Law or any
     provision of this Agreement or any other Transaction Document, or may
     require the Agent to qualify to do business in any jurisdiction where it is
     not then so qualified.

     8.03.  Exercise of Powers.  The Agent shall take any action of the type
            ------------------

the Agent's rights, powers or discretion in accordance with directions from the
Required Banks (or, to the extent this Agreement or such Transaction Document
expressly requires the direction or consent of some other Person or set of
Persons, then instead in accordance with the directions of such other Person or
set of Persons).  In the absence of such directions, the Agent shall have the
authority (but under no circumstances shall be obligated), in its sole
discretion, to take any such action, except to the extent this Agreement or such
Transaction Document expressly requires the direction or consent of the Required
Banks (or some other Person or set of Persons), in which case the Agent shall
not take such action absent such direction or consent.  Any action or inaction
pursuant to such direction, discretion or consent shall be binding on all the
Banks.  The Agent shall not have any liability to any Person as a result of (x)
the Agent acting or refraining from acting in accordance with the directions of
the Required Banks (or other applicable Person or set of Persons), (y) the Agent
refraining from acting in the absence of instructions to act from the Required
Banks (or other applicable Person or set of Persons), whether or not the Agent

received under or in connection with, this Agreement or any other Transaction
Document, (iii) any failure of any Credit Party or Bank to perform any of their
respective obligations 

                                      37
<PAGE>
 
under this Agreement or any other Transaction Document, or (iv) the existence,
validity, enforceability, perfection, recordation, priority, adequacy or value,
now or hereafter, of any Lien or other direct or indirect security afforded or
purported to be afforded by any of the Transaction Documents or otherwise from
time to time.

give any notice relating to (i) the performance or observance of any of the
terms or conditions of this Agreement or any other Transaction Document on the
part of any Credit Party, (ii) the business, operations, condition (financial or
otherwise) or prospects of any Credit Party or any other Person, or (iii) except
to the extent set forth in Section 8.05(f) hereof, the existence of any Event of
Default or Potential Default.

     (d)  The Agent shall not be under any obligation, either initially or on a

notices, reports and other information expressly required by this Agreement or
any other Transaction Document to be furnished by the Agent to such Bank.

     8.05.  Administration by the Agent.
            --------------------------- 

     (a)  The Agent may rely upon any notice or other communication of any
nature (written or oral, including but not limited to telephone conversations,
whether or not such notice or other communication is made in a manner permitted
or required by this Agreement or any Transaction Document) purportedly made by
or on behalf of the proper party or parties, and the Agent shall not have any
duty to verify the identity or authority of any Person giving such notice or
other communication.

     (b)  The Agent may consult with legal counsel (including, without
limitation, in-house counsel for the Agent or in-house or other counsel for any
Credit Party), independent public accountants and any other experts selected by
it from time to time, and the Agent shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
counsel, accountants or experts.

     (c)  The Agent may conclusively rely upon the truth of the statements and
the correctness of the opinions expressed in any certificates or opinions
furnished to the Agent in accordance with the requirements of this Agreement or
any other Transaction Document.  Whenever the Agent shall deem it necessary or
desirable that a matter be proved or established with respect to any Credit
Party or Bank, such matter may be established by a certificate of such Credit
Party or Bank, as the case may be, and the Agent may conclusively rely upon such
certificate (unless other evidence with respect to such matter is specifically
prescribed in this Agreement or another Transaction Document).

     (d)  The Agent may fail or refuse to take any action unless it shall be
indemnified to its satisfaction from time to time against any and all amounts,
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature which may be imposed on,
incurred by or asserted against the Agent by reason of taking or continuing to
take any such action.

     (e)  The Agent may perform any of its duties under this Agreement or any
other Transaction Document by or through agents or attorneys-in-fact.  The Agent
shall not be responsible for the negligence or misconduct of any agents or
attorneys-in fact selected by it with reasonable care.

     (f)  The Agent shall not be deemed to have any knowledge or notice of the
occurrence of any Event of Default or Potential Default unless the Agent has
received notice from a Bank or any Credit Party referring to this Agreement,
describing such Event of Default or Potential Default, and stating 


                                      38
<PAGE>
 
that such notice is a "notice of default". If the Agent receives such a notice,
the Agent shall give prompt notice thereof to each Bank.

     8.06.  Bank Not Relying on Agent or Other Banks.  Each Bank acknowledges as
            ----------------------------------------                            
follows:  (a) neither the Agent nor any other Bank has made any representations
or warranties to it, and no act taken hereafter by the Agent or any other Bank
shall be deemed to constitute any representation or warranty by the Agent or
such other Bank to it;  (b) it has, independently and without reliance upon the
Agent or any other Bank, and based upon such documents and information as it has
deemed appropriate, made its own credit and legal analysis and decision to enter
into this Agreement and the other Transaction Documents; and (c) it will,
independently and without reliance upon the Agent or any other Bank, and based
upon such documents and information as it shall deem appropriate at the time,
make its own decisions to take or not take action under or in connection with
this Agreement and the other Transaction Documents.

     8.07.  Indemnification.  Each Bank agrees to reimburse and indemnify the
            ---------------                                                  
Agent and its directors, officers, employees and agents (to the extent not
reimbursed by a Credit Party and without limitation of the obligations of the
Loan Parties to do so), ratably in accordance with their respective Letter of
Credit Participating Interests, from and against any and all amounts, losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements of any kind or nature (including,
without limitation, the reasonable fees and disbursements of counsel for the
Agent or such other Person in connection with any investigative, administrative
or judicial proceeding commenced or threatened, whether or not the Agent or such
other Person shall be designated a party thereto) that may at any time be
imposed on, incurred by or asserted against the Agent or such other Person as a
result of, or arising out of, or in any way related to or by reason of, this
Agreement, any other Transaction Document, any transaction from time to time
contemplated hereby or thereby, or any transaction to which a Letter of Credit
directly or indirectly relates, provided that no Bank shall be liable for any
                                --------                                     
portion of such amounts, losses, liabilities, claims, damages, expenses,
obligations, penalties, actions, judgments, suits, costs or disbursements
resulting solely from the gross negligence or willful misconduct of the Agent or
such other Person, as finally determined by a court of competent jurisdiction.
Payments under this Section shall be due and payable on demand, and to the
extent that any Bank fails to pay any such amount on demand, such amount shall
bear interest for each day from the date of demand until paid (before and after
judgment) at a rate per annum (calculated on the basis of a year of 360 days and
actual days elapsed) which for each day shall be equal to 2% over the interest
rate per annum announced by the Federal Reserve Bank of New York or otherwise
determined by the Agent to be applicable for such day to overnight federal funds
transactions arranged by federal funds brokers on the previous trading day.

     8.08.  Agent in its Individual Capacity.  With respect to its Commitments
            --------------------------------                                  
and the Obligations owing to it, the Agent shall have the same rights and powers
under this Agreement and each other Transaction Document as any other Bank and
may exercise the same as though it were not the Agent, and the terms "Banks" and
like terms shall include the Agent in its individual capacity as such.  The
Agent and its affiliates may, without liability to account, make loans to,
accept deposits from, acquire debt or equity interests in, act as trustee under
indentures of, act as agent under other credit facilities for, and engage in any
other business with, any Credit Party and any stockholder, subsidiary or
affiliate of any Credit Party, as though the Agent were not the Agent hereunder.

     8.09.  Successor Agent.  The Agent may resign at any time by giving 10
            ---------------                                                
days' prior written notice thereof to the Banks and the Account Parties.  The
Agent may be removed by the Required Banks at any time by giving 10 days' prior
written notice thereof to the Agent, the other Banks and the Account Parties.
Upon any such resignation or removal, the Required Banks shall have the right to
appoint a successor Agent.  If no successor Agent shall have been so appointed
and consented to, and shall have accepted such appointment, within 30 days after
such notice of resignation or removal, then the retiring Agent may, on behalf of
the Banks, appoint a successor Agent.  Each successor Agent shall be a
commercial bank or trust company organized under the laws of the United States
of America or 

                                      39
<PAGE>
 
any State thereof and having a combined capital and surplus of at least
$1,000,000,000. Upon the acceptance by a successor Agent of its appointment as
Agent hereunder, such successor Agent shall thereupon succeed to and become
vested with all the properties, rights, powers, privileges and duties of the
former Agent, without further act, deed or conveyance. Upon the effective date
of resignation or removal of a retiring Agent, such Agent shall be discharged
from its duties under this Agreement and the other Transaction Documents, but
the provisions of this Agreement shall inure to its benefit as to any actions
taken or omitted by it while it was Agent under this Agreement. If and so long
as no successor Agent shall have been appointed, then any notice or other
communication required or permitted to be given by the Agent shall be
sufficiently given if given by the Required Banks, all notices or other
communications required or permitted to be given to the Agent shall be given to
each Bank, and all payments to be made to the Agent shall be made directly to
the Account Parties or Bank for whose account such payment is made.

     8.10.  Additional Agents.  If the Agent shall from time to time deem it
            -----------------                                               
necessary or advisable, for its own protection in the performance of its duties
hereunder or in the interest of the Banks, the Agent and the Account Parties
shall execute and deliver a supplemental agreement and all other instruments and
agreements necessary or advisable, in the opinion of the Agent, to constitute
another commercial bank or trust company, or one or more other Persons approved
by the Agent, to act as co-Agent or agent with such powers of the Agent as may
be provided in such supplemental agreement and to vest in such bank, trust
company or Person as such co-Agent or separate agent, as the case may be, any
properties, rights, powers, privileges and duties of the Agent under this
Agreement or any other Transaction Document.

     8.11.  Calculations.  The Agent shall not be liable for any calculation,
            ------------                                                     
apportionment or distribution of payments made by it in good faith.  If such
calculation, apportionment or distribution is subsequently determined to have
been made in error, the sole recourse of any Bank to whom payment was due but
not made shall be to recover from the other Banks any payment in excess of the
amount to which they are determined to be entitled or, if the amount due was not
paid by the appropriate Account Party, to recover such amount from the
appropriate Account Party.

     8.12.  Agent's Fee.  X.L. Insurance agrees to pay to the Agent, for its
            -----------                                                     
individual account, a nonrefundable Agent's fee in an amount and at such time or
times as the Agent and X.L. Insurance have heretofore agreed.

in exercising any right, power or privilege hereunder shall affect such right,
power or privilege; nor shall any single or partial exercise thereof or any
abandonment or discontinuance of steps to enforce such a right, power or
privilege preclude any further exercise thereof or of any other right, power or
privilege.  The rights and remedies hereunder of the Agent and the Banks are
cumulative and not exclusive of any rights or remedies which, it or they would
otherwise have.  Any amendment, waiver, permit, consent or approval of any kind
or character on the part of the Agent or a Bank of any breach or default under

            -------                                                             
in Article VII hereof shall occur, each Bank shall have the right, in addition
to all other rights and remedies 

                                      40

available to it, to set-off against the unpaid balance of its interests in any
Letter of Credit Reimbursement Obligations any debt owing by such Bank to the
applicable Credit Party, including without limitation any funds in any deposit
account maintained by such Credit Party with such Bank, and such Bank shall have
and there is hereby created in favor of such Bank a security interest in all

counterclaim, set-off, banker's lien or other lien for application upon any

other Banks. Nothing in this Agreement shall be deemed any waiver or prohibition
of any right of banker's lien or set-off under applicable Law.

     9.03.  Survival of Provisions.  Each of the representations, warranties,
            ----------------------                                           
covenants and agreements of the Credit Parties contained herein or made in
writing in connection herewith shall survive the execution and delivery of this
Agreement, and the issuance of any Letter of Credit hereunder.

     9.04.  Expenses and Fees; Indemnity.
            ---------------------------- 

     (a)  Each Account Party agrees to pay or cause to be paid and to save the
Agent and (in the case of clause (iii) below) each of the Banks harmless against
liability for the payment of all reasonable out-of-pocket costs and expenses
(including but not limited to reasonable fees and expenses of counsel, including
local counsel, auditors, and all other professional, accounting, evaluation and
consulting costs) incurred by the Agent or such Bank from time to time arising
from or relating to (i) the negotiation, preparation, execution, delivery,
administration and performance of this Agreement and the other Transaction
Documents, (ii) any requested amendments, modifications, supplements, waivers or
consents (whether or not ultimately entered into or granted) to this Agreement
or any Transaction Document, and (iii) the enforcement or preservation of rights
under this Agreement or any Transaction Document (including but not limited to
any such costs or expenses arising from or relating to (A) collection or
enforcement of any other amount owing hereunder or thereunder by the Agent or
any Bank and (B) any litigation, proceeding, dispute, work-out, restructuring or
rescheduling related in any way to this Agreement or the Transaction Documents.
Notwithstanding the foregoing, an Account Party shall not be required to pay
costs and expenses of a Bank (in its capacity as such) which were incurred by
such Bank in connection with any litigation, proceeding or other dispute
relating solely to a claim made against such Bank by one or more of the other
Banks.  Each Account Party hereby agrees to pay all stamp, document, transfer,
recording, filing, registration, search, sales and excise fees and taxes and all
similar impositions now or hereafter determined by the Agent or any Bank to be
payable in connection with this Agreement or any other Transaction Documents or
any other documents, instruments or transactions pursuant to or in connection
herewith or therewith, and an Account Party agrees to save the Agent and each
Bank harmless from and against any and all present or future claims, liabilities
or losses with respect to or resulting from any omission to pay or delay in
paying any such fees.

     (b)  Each Account Party hereby agrees to reimburse and indemnify the Agent
and each Bank (the "Indemnified Parties") from and against any and all losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements of any kind or nature whatsoever
(including, without limitation, the fees and disbursements of counsel for the
Indemnified Parties in connection with any investigative, administrative or
judicial proceeding commenced or threatened, whether or not such Indemnified
Party shall be designated a party thereto) that may at any time be imposed on,
asserted against or incurred by such Indemnified Party as a result of, or
arising out of, or in any way related to or by reason of, this Agreement or any
other Transaction Document, any transaction from time to time contemplated
hereby or thereby, or any transaction  to which any Letter of Credit directly or
indirectly relates (and without in any way limiting the generality of the
foregoing, including any violation or breach of any Law by any Credit Party or
any exercise by the Agent or any Bank of any of its rights or remedies under

                                      41
<PAGE>
 
this Agreement or any other Transaction Document; any breach of any
representation or warranty, covenant or agreement of any Credit Party); but
excluding any such losses, liabilities, claims, damages, expenses, obligations,
penalties, actions, judgments, suits, costs or disbursements to the extent
resulting from the gross negligence or willful misconduct of such Indemnified
Party, as finally determined by a court of competent jurisdiction. If and to the
extent that the foregoing obligations of the Account Parties under this Section
9.04, or any other indemnification obligation of the Account Parties hereunder
or under any other Transaction Document, are unenforceable for any reason, the
Account Parties hereby agree to make the maximum contribution to the payment and
satisfaction of such obligations which is permissible under applicable Law.
Notwithstanding the foregoing, an Account Party shall not be required to pay
costs and expenses of a Bank (in its capacity as such) which were incurred by
such Bank in connection with any litigation, proceeding or other dispute
relating solely to a claim made against such Bank by one or more of the other
Banks.

     9.05.  Severability.  In the event any one or more of the provisions
            ------------                                                 
contained in this Agreement or in any other Transaction Document should be held
invalid, illegal or unenforceable in any respect, the validity, legality and
enforceability of the remaining provisions contained herein and therein shall
not in any way be affected or impaired thereby.  The parties shall endeavor in
good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

     9.06.  Holidays.  Unless otherwise specified herein, whenever any payment
            --------                                                          
or action to be made or taken hereunder shall be stated to be due on a Saturday,
Sunday or public holiday under the laws of the Commonwealth of Pennsylvania or
Bermuda, such payment or action shall be made or taken on the next succeeding
Business Day and such extension of time shall in such case be included in
computing interest, if any, in connection with such payment or action.

     9.07.  Notices, etc.  Any notice or other communication in connection with
            ------------

Agent, and their respective successors and assigns, except that no Credit Party

          (i)  any such participation sold to a Participant which is not a Bank,
     an affiliate of a Bank or a Federal Reserve Bank shall be made only with
     the consent (which in each case shall not be unreasonably withheld) of X.L.

     Default has occurred and is continuing, in which case the consent of the

     Bank, or is itself a Bank) shall be entitled to require such Bank to take
     or refrain from taking action under this Agreement or under any other
     Transaction Document, except that such Bank may agree with such Participant
     that such Bank will not, without such Participant's consent, take action of
     the type described in subsections (a), (b), (c) or (d) of Section 9.14
     hereof, and

     to this Agreement only in connection with amendments which effect changes
     in the amount of Letter of Credit Participating Interest Commitments,
     Letter of Credit Participating Interests, fees payable hereunder and the
     Expiration Date.

Each Account Party agrees that any such Participant shall be entitled to the
benefits of Sections 2.09 and 9.04 with respect to its participation in the
Commitments and the Letters of Credit outstanding from time to time; provided,
                                                                     --------

receive in respect of the amount of the participation transferred to such
Participant had no such transfer occurred.

     (c)  Assignments.  Any Bank may, in the ordinary course of its commercial
          -----------

          (i)   any such assignment to a Purchasing Bank which is not a Bank, an
     affiliate of a Bank or a Federal Reserve Bank shall be made only with the
     consent (which in each case shall not be unreasonably withheld) of X.L.
     Insurance and the Agent, unless an Event of Default has occurred and is
     continuing or exists, in which case the consent of X.L. Insurance shall not
     be required,

          (ii)  if a Bank makes such an assignment of less than all of its then
     remaining rights and obligations under this Agreement and the other
     Transaction Documents, such assignment shall be in a minimum aggregate
     principal amount of $10,000,000 of the Letter of Credit Participating
     Interest Commitments and Letter of Credit Participating Interests then
     outstanding,

     Transaction Documents, and

          (iv)  each such assignment shall be made pursuant to a Transfer
     Supplement in substantially the form of Exhibit B to this Agreement, duly
     completed (a "Transfer Supplement").

          In order to effect any such assignment, the transferor Bank and the
     Purchasing Bank shall execute and deliver to the Agent a duly completed
     Transfer Supplement (including the consents required by clause (i) of the
     preceding sentence) with respect to such assignment, and a processing and
     recording fee of $2,500; and, upon receipt thereof, the Agent shall accept
     such Transfer Supplement; provided, however, that no such processing and
                               --------  -------                             
     recording fee shall be due if such assignment is to an affiliate of a Bank
     or a Federal Reserve Bank .  Upon receipt of the Purchase Price Receipt
     Notice pursuant to such Transfer Supplement, the Agent shall record such
     acceptance in the Register.  Upon such execution, delivery, acceptance and
     recording, from and after the close of business at the Agent's Office on
     the Transfer Effective Date specified in such Transfer Supplement.

          (x)  the Purchasing Bank shall be a party hereto and, to the extent
     provided in such Transfer Supplement, shall have the rights and obligations
     of a Bank hereunder, and

          (y)  the transferor Bank thereunder shall be released from its
     obligations under this Agreement to the extent so transferred (and, in the
     case of an Transfer Supplement covering all or the remaining portion of a
     transferor Bank's rights and obligations under this Agreement, such
     transferor Bank shall cease to be a party to this Agreement) from and after
     the Transfer Effective Date.

     (d)  Register.  The Agent shall maintain at its office a copy of each
          --------                                                        
Transfer Supplement delivered to it and a register (the "Register") for the
recordation of the names and addresses of the banks and the Letter of Credit
Participating Interest Commitment of, and the amount of the Letter of Credit
Participating Interests of, each Bank from time to time.  The entries in the
Register shall be conclusive absent manifest error and the Account Parties, the
Agent and the Banks may treat each person whose name is recorded in the Register
as a Bank hereunder for all purposes of the Agreement.  The Register shall be
available for inspection by an Account Party or any Bank at any reasonable time
and from time to time upon reasonable prior notice.

     (e)  Financial and Other Information.  Each Credit Party authorizes the
          -------------------------------                                   
Agent and each Bank to disclose to any Participant or Purchasing Bank (each, a
"transferee") and any prospective transferee any and all financial and other
information in such Person's possession concerning the Credit Parties and their
affiliates which has been or may be delivered to such Person by or on behalf of
the Credit Parties in connection with this Agreement or any other Transaction
Document or such Person's credit evaluation of the Credit Parties and their
affiliates.  At the request of any Bank, a Credit Party, at a Credit Party's
expense, shall provide to each prospective transferee the conformed copies of
documents referred to in Section 4 of the form of Transfer Supplement.

     9.14.  Amendments and Waivers.  Neither this Agreement nor any Transaction
            ----------------------                                             
Document may be amended, modified or supplemented except in accordance with the
provisions of this Section.  The Agent and the Credit Parties may from time to
time amend, modify or supplement the provisions of this Agreement or any other
Transaction Document for the purpose of amending, adding to, or waiving any
provisions or changing in any manner the rights and duties of any Credit Party,
the Agent or any Bank.  Any such amendment, modification or supplement made by
the Credit Parties and the Agent in accordance with the provisions of this
Section shall be binding upon the Credit Parties, each Bank and the Agent.  The
Agent shall enter into such amendments, modifications or supplements from time
to 

                                      45
<PAGE>
 
time as directed by the Required Banks, and only as so directed, provided,
                                                                 -------- 
that no such amendment, modification or supplement may be made which will:

     (a)  Increase the Letter of Credit Participating Interest Committed Amount
of any Bank over the amount thereof then in effect, or extend the Expiration
Date, without the written consent of each Commitment Bank affected thereby;

     (b)  Reduce the amount of or postpone the date for payment of any
Commitment Fee or Letter of Credit Fee or reduce or postpone the date for
payment of any other fees, expenses, indemnities or amounts payable under any
Transaction Document, without the written consent of each Bank affected thereby;

Guarantor from its obligations hereunder without the written consent of all the
Banks; or

     (f)  Amend the definition of Qualifying Pledged Securities or of Required
Pledged Securities (as each such term is defined herein and in the Pledge
Agreement) or release all or (except in accordance with the terms of the Pledge
Agreement) any material part of the Collateral under the Pledge Agreement or
release X.L. Investments from all of its obligations as the Grantor thereunder,
without the written consent of all of the Banks;

and provided further, that Transfer Supplements may be entered into in the
    ----------------                                                      
manner provided in Section 9.13 hereof.  Any such amendment, modification or
supplement must be in writing and shall be effective only to the extent set
forth in such writing.  Any Event of Default or Potential Default waived or
consented to in any such amendment, modification or supplement shall be deemed
to be cured and not continuing to the extent and for the period set forth in
such waiver or consent, but no such waiver or consent shall extend to any other
or subsequent Event of Default or Potential Default or impair any right
consequent thereto.  Implementation of a Future Collateral Allocation
Transaction (as defined in Section 8.01(b) hereof) shall require the consent of
the Required Banks, the Issuing Bank and the Agent, but shall not require the
consent of all of the Banks.

     9.15.  Judgment Currency.  In the event of a judgment or order being
            -----------------                                            
rendered by any court or tribunal for the payment of any amounts owing to the
Banks or any of them under this Agreement or any other Transaction Document or
for the payment of damages in respect of any breach of this Agreement or any
other Transaction Document or under or in respect of a judgment or order of
another court or tribunal for the payment of such amounts or damages, such
judgment or order being expressed in a currency (the "Judgment Currency") other
than Dollars the party against whom the judgment or order is made shall
indemnify and hold the Banks harmless against any deficiency in terms of Dollars
in the amounts received by the Banks arising or resulting from any variations as
between (i) the exchange rate at which Dollars are converted into the Judgment
Currency for the purposes of such judgment or order and (ii) the exchange rate
at which each Bank is able to purchase Dollars with the amount of the Judgment
Currency actually received by the Banks on the date of such receipt.  The
indemnity in this section shall constitute a separate and independent obligation
from the other obligations of the Account Parties hereunder and shall apply
irrespective of any indulgence granted by the Banks.

                                      46
<PAGE>
 
     9.16.  Records.  The amount of outstanding Letters of Credit, each Bank's
            -------                                                           
Letter of Credit Participating Interest Committed Amount and the accrued and
unpaid Commitment Fees shall at all times be ascertained from the records of the
Agent, which shall be conclusive absent manifest error.

     9.17  Confidentiality.  Each of the Agent and the Banks agree to keep
           ---------------                                                
confidential any information relating to the Credit Parties received by it
pursuant to or in connection with this Agreement which is (a) information which
the Agent and the Banks reasonably expect that the applicable Credit Party would
want to keep confidential or (b) information which is clearly marked
"CONFIDENTIAL"; provided, however, that this Section 9.17 shall not be construed
to prevent the Agent or any Bank from disclosing such information (i) to any
affiliate that shall agree in writing for the benefit of the Credit Parties to
be bound by this obligation of confidentiality, (ii) upon the order of any court
or administrative agency of competent jurisdiction, (iii) upon the request or
demand of any regulatory agency or authority having jurisdiction over the Agent
or such Bank which request or demand has the force of Law or is made by a bank
regulatory agency, (iv) that has been publicly disclosed, other than from a
breach of this provision by the Agent or any Bank, (v) that has been obtained
from any person that is neither a party to this Agreement nor an affiliate of
any such party, but only to the extent that such Bank does not know or have
reason to know that such disclosure violates a confidentiality agreement between
such person and the applicable Credit Party (vi) in connection with the exercise
of any right or remedy hereunder or under any other Transaction Document, (vii)
as expressly contemplated by this Agreement or any other Transaction Document or
(viii) to any prospective purchaser of all or any part of the interest of any
Bank which shall agree in writing for the benefit of the Credit Parties to be
bound by the obligation of confidentiality in this Agreement or the other
Transaction Documents if such prospective purchaser is a financial institution
or has been consented to by the Account Parties, which consent will not be
withheld if such purchaser is not a competitor of any Account Party or an
affiliate of a competitor of any Account Party.

     9.18.  Sharing of Collections.  The Banks hereby agree among themselves
            ----------------------                                          
that if any Bank shall receive (by voluntary payment, realization upon security,
set-off or from any other source) any amount on account of any Obligation
contemplated by this Agreement or the other Transaction Documents to be made by
an Account Party pro rata to all Banks in greater proportion than any such
amount received by any other Bank, then the Bank receiving such proportionately
greater payment shall notify each other Bank and the Agent of such receipt, and
equitable adjustment will be made in the manner stated in this Section 9.18 so
that, in effect, all such excess amounts will be shared ratably among all of the
Banks.  The Bank receiving such excess amount shall purchase (which it shall be
deemed to have done simultaneously upon the receipt of such excess amount) for
cash from the other Banks a participation in the applicable Obligations owed to
such other Banks in such amount as shall result in a ratable sharing by all
Banks of such excess amount (and to such extent the receiving Bank shall be a
Participant).  If all or any portion of such excess amount is thereafter
recovered from the Bank making such purchase, such purchase shall be rescinded
and the purchase price restored to the extent of such recovery, together with
interest or other amounts, if any, required by Law to be paid by the Bank making
such purchase.  The Account Parties hereby consent to and confirm the foregoing
arrangements.  Each Participant shall be bound by this Section 9.18 as fully as
if it were a Bank hereunder."

                                   GUARANTEE
                                   ---------

     10.01.  The Guarantee.  Each of the Guarantors hereby irrevocably,
             -------------                                             
unconditionally and absolutely guarantees to the Agent and the Banks, and
becomes surety for, the prompt payment of the Obligations of the Account Parties
(the "Guaranteed Obligations") in full when due (whether at stated maturity, by
acceleration, or otherwise) strictly in accordance with the terms thereof.  Each


                                      47
<PAGE>
 
Guarantor hereby further agrees, as a primary obligor, that if any of the
Guaranteed Obligations are not paid in full when due (whether at stated
maturity, by acceleration, or otherwise and whether or not such payments would
not be permitted under any applicable bankruptcy or similar law), the Guarantor
will promptly pay the same, without any demand or notice whatsoever (except as
expressly provided herein), and that in the case of any extension of time of
payment or renewal of any of the Guaranteed Obligations, the same will be
promptly paid in full when due (whether at extended maturity, by acceleration or
otherwise) in accordance with the terms of such extension or renewal.

Notwithstanding any provision to the contrary contained herein or in any other
of the Transaction Documents, to the extent the obligations of either Guarantor
shall be adjudicated to be invalid or unenforceable for any reason (including,
without limitation, because of any applicable law, including the insolvency
laws, relating to fraudulent conveyances or transfers) then the obligations of
such Guarantor hereunder automatically shall be limited to the maximum amount
that is permissible under applicable law.

     10.02.  Obligations Unconditional.  The obligations of each Guarantor under
             -------------------------                                          
this Article are irrevocable, absolute and unconditional (to the fullest extent
permitted by applicable law), irrespective of the value, genuineness, validity,
regularity or enforceability of any of the Transaction Documents, or any other
agreement or instrument referred to therein, or any substitution, release or
exchange of any other guarantee of or security for any of the Guaranteed
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Article that the obligations of each Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.
Each Guarantor agrees that such Guarantor shall have no right of subrogation,
indemnity, reimbursement or contribution against any Account Party, for amounts
paid under this Article X until such time as the Banks have been paid in full,
no Letter of Credit is outstanding, the Letter of Credit Participating Interest
Commitments under this Agreement have been terminated and no Person or Official
Body shall have any right to request any return or reimbursement of funds from
any Bank in connection with monies received under the Transaction Documents.
Without limiting the generality of the foregoing, it is agreed that, to the
fullest extent permitted by applicable law, the occurrence of any one or more of
the following shall not alter or impair the liability of either Guarantor
hereunder which shall remain irrevocable, absolute and unconditional as
described above:

           (i)  at any time or from time to time, without notice to the
     Guarantors, the time for any performance of or compliance with any of the
     Guaranteed Obligations shall be extended, or such performance or compliance
     shall be waived;

          (ii)  any of the acts mentioned in any of the provisions of any of the
     Transaction Documents, or any other agreement or instrument referred to in
     the Transaction Documents shall be done or omitted;

          (iii) the maturity of any of the Guaranteed Obligations shall be
     accelerated, or any of the Guaranteed Obligations shall be modified,
     supplemented or amended in any respect, or any right under any of the
     Transaction Documents, or any other agreement or instrument referred to in
     the Transaction Documents shall be waived or any other guarantee of any of
     the Guaranteed Obligations or any security therefor shall be released or
     exchanged in whole or in part or otherwise dealt with;

          (iv)  any Lien granted to, or in favor of, the Agent or any Bank as
     security for any of the Guaranteed Obligations shall be void or violable,
     or shall fail to attach or be perfected or the Agent or any Bank shall fail
     to realize on any collateral security; or


                                      48
<PAGE>
 
          (v)  any of the Guaranteed Obligations shall be determined to be void
     or violable (including, without limitation, for the benefit of any creditor
     of either Guarantor) or shall be subordinated to the claims of any Person
     (including, without limitation, any creditor of either Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever (except notices expressly required hereunder), and any requirement
that the Banks exhaust any right, power or remedy or proceed against any Person
under any of the Transaction Documents, or any other agreement or instrument
referred to in the Transaction Documents, or against any other Person under any
other guarantee of, or security for, any of the Guaranteed Obligations.  This is
a guarantee of payment and not merely of collection.

     10.03.  Reinstatement.  The obligations of the Guarantors under this
             -------------                                               
Article shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of any Person in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in
bankruptcy, receivership, or reorganization or otherwise, and each Guarantor
agrees that it will indemnify the Agent and the Banks on demand for all
reasonable out-of-pocket costs and expenses (including, without limitation,
reasonable fees and expenses of counsel) incurred by the Agent or any Bank in
connection with such rescission or restoration, including any such reasonable
costs and expenses incurred in defending against any claim alleging that such
payment constituted a preference, fraudulent transfer or similar payment under
any bankruptcy, insolvency, receivership, reorganization or similar law.

     10.04.  Remedies.  Each Guarantor agrees that, to the fullest extent
             --------                                                    
permitted by applicable law, as between such Guarantor, on the one hand, and the
Agent and the Banks, on the other hand, the Guaranteed Obligations may be
declared to be forthwith due and payable as provided in Section 7.01 hereof (and
shall be deemed to have become automatically due and payable in the
circumstances provided in said Section 7.01) for purposes of Section 10.01
hereof notwithstanding any stay, injunction or other prohibition preventing such
declaration (or preventing the Guaranteed Obligations from becoming
automatically due and payable) as to any other Person and that, in the event of
such declaration (or Guaranteed Obligations being deemed to have become
automatically due and payable), the Guaranteed Obligations (whether or not due
and payable by any other Person) shall forthwith become due and payable by such
Guarantor for purposes of said Section 10.01.

     10.05.  Continuing Guarantee.  The guarantee in this Article is a
             --------------------                                     
continuing guarantee, and shall apply to all of the Guaranteed Obligations
whenever arising.

     10.06.  No Restrictions.  Except for restrictions under the Transaction
             ---------------                                                
Documents, neither Guarantor shall be or become subject to any restriction of
any nature (whether arising by operation of Law, by agreement, by its articles
of incorporation, by-laws or other constituent documents of such Guarantor, or
otherwise) on the right of such Guarantor from time to time to (x) pay any
indebtedness, obligations or liabilities from time to time owed to any Account
Party, (y) make loans or advances to my Account Party, or (z) transfer any of
its properties or assets to my Account Party.

          WHEREAS, the Borrowers have requested the Banks to make certain
changes to the Credit Agreement; and

          WHEREAS, the Banks are willing to amend the Credit Agreement as set
forth below; and

          WHEREAS, capitalized terms used herein and not otherwise defined shall
have the meanings assigned to them in the Credit Agreement;

          NOW THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, and intending to be legally bound hereby, the
parties hereto agree as follows:

          SECTION 1.  AMENDMENTS TO CREDIT AGREEMENT.  The Credit Agreement is
                      ------------------------------                          
hereby amended as follows:

     (a)  Section 2.05(a) is hereby amended by deleting the term
     "Section 2.11(b)" in the first sentence thereof and replacing it
     with the term "Section 2.10(b)".

     (b)  Section 6.08(c) is hereby amended by deleting Section
     6.08(c) in its entirety and substituting the following:

          "Reimbursement obligations with respect to letters of credit
     not exceeding $500,000,000 in aggregate principal amount, of
     which $500,000,000 may be secured;"

     (c)  Schedule 6.08(d) is hereby amended by adding the following
     at the end thereof:

          
          "Upon the closing of a secured letter of credit facility 
     providing for the issuance of letters of credit in


<PAGE>
 
     an aggregate face amount of $500,000,000 between the Borrowers, certain
     affiliates of the Borrowers, Mellon Bank, N.A., as Agent and Issuing Bank
     and the other banks parties thereto, all of the letters of credit listed on
     this Schedule 6.08(d) shall be deleted.

     (d)  A new Section 9.18 shall be added to the Credit Agreement as follows:

          "9.18 Sharing of Collections. The Banks hereby agree among themselves
                ----------------------                                         
     that if any Bank shall receive (by voluntary payment, realization upon
     security, set-off or from any other source) any amount on account of the
     Loans, interest thereon, or any other Obligation contemplated by this
     Agreement or the other Loan Documents to be made by the Borrowers pro rata
     to all Banks in greater proportion than any such amount received by any
     other Bank, then the Bank receiving such proportionately greater payment
     shall notify each other Bank and the Agent of such receipt, and equitable
     adjustment will be made in the manner stated in this Section 9.18 so that,
     in effect, all such excess amounts will be shared ratably among all of the
     Banks.  The Bank receiving such excess amount shall purchase (which it
     shall be deemed to have done simultaneously upon the receipt of such excess
     amount) for cash from the other Banks a participation in the applicable
     Obligations owed to such other Banks in such amount as shall result in a
     ratable sharing by all Banks of such excess amount (and to such extent the
     receiving Bank shall be a Participant).  If all or any portion of such
     excess amount is thereafter recovered from the Bank making such purchase,
     such purchase shall be rescinded and the purchase price restored to the
     extent of such recovery, together with interest or other amounts, if any,
     required by Law to be paid by the Bank making such purchase.  The Borrower
     hereby consents to and confirms the foregoing arrangements.  Each
     Participant shall be bound by this Section 9.18 as fully as if it were a
     Bank hereunder."

          SECTION 2.  EFFECT OF AMENDMENT.  The Credit Agreement, as amended by
                      -------------------                                      
this Amendment, is in all respects ratified, approved and confirmed and shall,
as so amended, remain in full force and effect.

          SECTION 3.  GOVERNING LAW.  This Amendment shall be deemed to be a
                      -------------                                         
contract under the laws of the Commonwealth of Pennsylvania and for all purposes
shall be governed by and construed and enforced in accordance with the laws of
said Commonwealth.

          SECTION 4.  COUNTERPARTS.  This Amendment may be executed in any
                      ------------                                        
number of counterparts and by the different parties hereto on separate
counterparts, each of which, when so executed, shall be deemed an original, but

               principal amount of the Loan made by the Bank and to pay interest
               thereon shall be evidenced in part by two promissory notes of the
