ITEM 1. BUSINESS

RECENT DEVELOPMENTS

     On June 18, 1999, XL Capital Ltd (sometimes referred to as the "Company")
merged with NAC Re Corp., a Delaware corporation, in a stock merger.
Shareholders of NAC received 0.915 Company shares for each NAC share in a tax
free exchange. Approximately 16.9 million of the Company's Class A ordinary
shares were issued in this transaction.

     The NAC merger was accounted for as a pooling of interests under U.S.
generally accepted accounting principles ("U.S. GAAP"). Accordingly, all prior
period information contained in this document includes the results of NAC as
though it had always been a part of the Company. Following the merger, the
Company changed its fiscal year end from November 30(th) to December 31(st) as a
conforming pooling adjustment. Consolidated financial information presented
herein is based upon the new fiscal year end for all years presented.

HISTORY

     The Company was incorporated with limited liability under the Cayman
Islands Companies Act on March 16, 1998, as EXEL Merger Company. The Company was
formed as a result of the merger of EXEL Limited and Mid Ocean Limited on
August 7, 1998, and was renamed EXEL Limited on that date. The merger was
accounted for as a purchase business combination. EXEL and Mid Ocean are
companies that were incorporated in the Cayman Islands in 1986 and 1992,
respectively. At class meetings held in August 1998, the shareholders of EXEL
and Mid Ocean approved Schemes of Arrangement under Cayman Islands law pursuant
to which EXEL and Mid Ocean became wholly-owned subsidiaries of the Company.
Following the merger, Mid Ocean's two main operating subsidiaries, a reinsurance
company and a Lloyd's managing agency with two dedicated corporate syndicates,
were combined with the Company's liability insurance business. At a special
general meeting held on February 1, 1999, the shareholders of the Company
approved a resolution changing the name of the Company to XL Capital Ltd. The
Company, through its subsidiaries, is a leading provider of insurance and
reinsurance coverages and financial products to industrial, commercial, and
professional service firms, insurance companies and other enterprises on a
worldwide basis.

     NAC was organized in 1985 and, through its subsidiaries, writes property
and casualty insurance and reinsurance in the U.S., Canada and Europe.

     In 1999, the Company made the following investments:

     (1) The Company further expanded into the United States by completing the
acquisition of both Intercargo Corporation and ECS, Inc. Intercargo is
headquartered in Schaumburg, Illinois, and through its subsidiaries, underwrites
specialty insurance products for companies engaged in international trade,
including U.S. Customs bonds and marine cargo insurance. ECS is an underwriting
manager headquartered in Exton, Pennsylvania, which specializes in environmental
insurance coverages and risk management services.

     (2) The Company signed a joint venture agreement with Les Mutuelles du Mans
Assurances Group to form a new French reinsurance company, Le Mans Re. The
Company owns a 49% shareholding in the new company, which underwrites a
worldwide portfolio comprising all classes of non-life reinsurance business
together with a selective portfolio of life reinsurance business.

     (3) The Company made strategic minority investments in two investment
management firms, Highfields Capital Management L.P., a global equity investment
firm, and MKP Capital Management, a New York-based fixed income investment
manager specializing in mortgage-backed securities.

                                       1
<PAGE>
     In 1998, the Company made the following investments:

     (1) The Company entered into a joint venture with FSA Holdings Ltd. to
write financial guaranty insurance and reinsurance. 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.

     (2) The Company formed Reeve Court Insurance Ltd., a Bermuda company
organized as a joint venture with that company's management for the purpose of
providing life insurance to high net worth individuals.

     (3) The Company formed two companies now known as XL Insurance Company of
New York and XL Capital Assurance. XL Insurance Company of New York is a
property and casualty insurance company, and XL Capital Assurance is a financial
guaranty insurance company.

     In 1997, the Company made the following investments:

     (1) The Company acquired GCR Holdings Limited, whose reinsurance subsidiary
was amalgamated with the Company's reinsurance operations.

     (2) The Company acquired a 75% holding in Latin America Re, a Bermuda
reinsurance company.

     (3) The Company formed Sovereign Risk Insurance, a Bermuda-based managing
general agency, as a joint venture to write political risk insurance on a
subscription basis on behalf of its shareholders.

     In 1996, the Company acquired 30% of Pareto Partners, a firm which
specializes in foreign currency management and related services.

OPERATIONS

     The Company is organized into four underwriting segments - insurance,
reinsurance, Lloyd's Syndicates and financial services - and a corporate
segment, which includes the investment operations of the Company. The
descriptions of policies and coverages which follow are summary in nature. Only
the terms and conditions of individual policies or contracts have legal effect,
and nothing in this report constitutes an admission of coverage or other
liability or interpretation of any particular policy provision.

     INSURANCE OPERATIONS

     The Company provides both excess and primary insurance globally through the
following subsidiaries: XL Insurance, XL Europe, XL Insurance Company of New
York, Greenwich Insurance, Indian Harbor Insurance, ECS and Intercargo.

     The Company provides third party general liability insurance, 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. The
liability insurance is written on an excess basis and the loss experience is
characterized as low frequency and high severity. The Company generally requires
that disputes arising under the policies be settled by arbitration in London.

     General liability coverage is typically provided on an occurrence-reported
policy form, with up to a maximum limit of $200 million per occurrence and in
the annual aggregate. Policies typically cover occurrences causing unexpected
and unintended personal injury, or property damage 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. Traditional occurrence coverage is also
available for restricted classes of risk and is generally written on a
follow-form basis, i.e. the policy generally adopts the terms, conditions and
exclusions of the underlying policy, currently up to a maximum of $50 million
per occurrence in excess of a minimum attachment point of $25 million.

                                       2
<PAGE>
     Directors and Officers coverage is written on a follow-form claims-made
basis providing up to a maximum limit of $75 million on both a primary and
excess basis.

     Professional liability risks are also generally written on a follow-form
basis. Coverage is provided for certain categories of risk up to a maximum of
$50 million with a minimum attachment of $20 million.

     Employment practices liability risks are written on a claims-made and
reported policy. The policy covers claims brought by an employee against an
insured for certain employment practices, up to a maximum of $100 million annual
aggregate limit in excess of a minimum attachment point of $0.5 million.

     Property insurance risks are written on a follow-form basis, which usually
provides coverage for all risks of physical damage and business interruption up
to a maximum limit of $100 million per occurrence, with a sub-limit of up to
$25 million for coverage in critical earthquake zones. Property insurance is
written on both a pro rata and excess basis. 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.

     The Company offers multi-year combined line coverages for traditional
casualty coverages including general, directors and officers liability,
professional liability and property coverage, in addition to a blended finite
coverage for risks which traditionally have been difficult to place through pure
risk transfer mechanisms.

     Primary program insurance risks written include specialty insurance such as
auto warranty business, environmental insurance, U.S. Customs bonds and marine
cargo insurance.

     REINSURANCE OPERATIONS

     The Company, through NAC Re and XL Mid Ocean Re, provides a broad range of
property and casualty reinsurance products on a global basis. Business is
written on both a proportional and excess of loss basis.

     The Company's casualty reinsurance is provided on a treaty and facultative
basis and includes general liability, professional liability, automobile and
workers' compensation, and commercial and personal property risks and specialty
risks, including fidelity and surety and ocean marine. Business is written on an
excess of loss basis, under which the Company indemnifies an insurer for a
portion of the losses on insurance policies in excess of a specified loss
amount, generally $1 million or more, and up to an amount per loss specified in
the contract. It is also written on a pro rata basis under which the Company
assumes from the primary insurer a percentage of loss specified in the treaty of
each risk in the reinsured class.

     The Company's property business is primarily short-tail in nature and
includes 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. A significant portion of 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.

     The Company's property catastrophe reinsurance account is generally "all
risk" in nature. It is therefore exposed to losses from sources as diverse as
windstorms, earthquakes, freezes, riots, floods, industrial explosions, fires or
any number of other potential disasters. In accordance with market practice, the
Company's policies generally exclude certain risks such as war, nuclear
contamination or radiation. The Company's predominant exposure under such
coverage is to property damage. 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 the Company's property catastrophe contracts
limit coverage to one occurrence in any one policy year, but most contracts
generally provide for one reinstatement.

     The Company also writes property risk excess of loss reinsurance. 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.

                                       3
<PAGE>
     The Company's property pro rata account includes proportional reinsurance
of direct property insurance. The Company considers this business to be related
to its catastrophe and other property exposures. In proportional reinsurance,
the Company 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 Company, and the ceding insurer
may also be entitled to receive a profit commission based upon the ratio of
losses, loss adjustment expense and the Company's expenses to premium ceded. The
Company is dependent upon the ceding insurer's underwriting, pricing and claims
administration to yield an underwriting profit. In some instances, the Company
may be entitled to the benefit of other reinsurance, known as common account
reinsurance, purchased by the ceding company on an account reinsured by the
Company on a proportional basis.

     The aviation portfolio is written on both a proportional and excess of loss
basis. The exposures are mainly derived through proportional relationships on
defined segments of account following market leaders in the field. Due to the
highly technical nature of the satellite business, the exposures retained under
this portfolio are acquired mostly through proportional reinsurances of
specialist underwriters.

     Other reinsurance written by the Company includes political risk, nuclear
accident, professional indemnity and life and annuity.

     LLOYD'S OPERATIONS

     The Company's Lloyd's operations are conducted by Brockbank and Denham.
Brockbank operates through two subsidiaries, which are Lloyd's managing general
agencies, Brockbank Syndicate Management and Brockbank Personal Lines. These
Brockbank subsidiaries manage five syndicates, two of which are dedicated
corporate syndicates whose capital is provided solely by the Company. During
1999, these dedicated corporate syndicates (syndicates 1209 and 2253) wrote a
range of specialty lines, primarily of insurance but also reinsurance, in
parallel with the other syndicates managed by Brockbank (syndicates 588, 861 and
253). Effective January 1, 2000, motor business is no longer written. Denham is
a Lloyd's managing agency which manages one Lloyd's syndicate (syndicate 990),
whose capital is partially provided by the Company and which writes casualty and
non-marine physical damage insurance. As managing agencies, Brockbank and Denham
receive fees and commissions in respect of the underwriting services they
provide to syndicates.

     Corporate syndicate 1209 writes a wide range of classes across the
property, casualty and marine, aviation and transport sectors to a globally
diverse group of clients. Coverages range from global "all risks" programs for
multinationals to tailored facilities for agents with small and medium sized
businesses, with particular emphasis on North America and Europe. The
syndicate's specie account includes fine art, cash in transit, financial
institutions and jewelry. The syndicate's accident and health account is
worldwide and comprises personal accident insurance and reinsurance, medical
expenses and kidnap and ransom. The professional indemnity account includes
professional and directors and officers liability and fidelity, with particular
emphasis in the service sectors (financial institutions, lawyers, information
technology, architects and engineers) in North America. Other business written
by the Company's Lloyd's operations includes the bloodstock account and
contingency coverages.

     Through the marine, hull and machinery account, syndicate 1209 has a
significant involvement with many of the world's largest fleets. The syndicate's
energy account comprises cover for all elements of the worldwide hydrocarbon
industry. The syndicate writes a space account and is involved at every stage of
major space launches and associated pre-launch operations. The marine liability
account embraces all the major types of cover available, including pollution
insurance, financiers' exposures and certificates of financial responsibility
reinsurance, as well as the more traditional liability cover, such as
charterers' liabilities. The syndicate writes a broad international cargo
account, specializing in the technology sector and in large plant and project
equipment. The syndicate also writes war and political risk cover for ships and
aircraft, and also covers most political risks, including expropriation,
confiscation, terrorism and trade disruption.

     Syndicate 1209's treaty reinsurance account provides high excess or
catastrophe cover predominantly for direct insurers. This account is diverse and
consists of protections for companies ranging from the large worldwide
multi-line insurers to the small domestic industrial mutual insurers. Excess of
loss coverage is provided for most lines of insurance. Syndicate 1209 also
writes a book of non-proportional treaty reinsurance business.

                                       4
<PAGE>
     Until December 1999, syndicate 2253 wrote an account of direct and broker
based motor insurance in the United Kingdom, an account which was also written
by syndicate 1209. This business was offered through two distribution channels:
Admiral Insurance, a direct response motor operation, and Zenith Insurance,
which offered motor insurance through a network of retail brokers. Admiral
concentrated on the private car market. Zenith operated across a broader range
of activities, covering areas such as taxis, motorcycles, agricultural vehicles
and commercial fleets, as well as private cars. In December 1999, Brockbank sold
Admiral and Zenith. The Company expects decreases in premiums, fee income and
certain costs as a result of the sale, however it does not expect the overall
profitability of its Lloyd's operations to be significantly affected by such
sales.

     FINANCIAL SERVICES

     The Company, through XL Capital Products, provides credit enhancement
coverages in the form of financial guaranty insurance and reinsurance and credit
default swaps on asset-backed, municipal and select corporate risk obligations.
Financial guaranty insurance generally guarantees payments of interest and
principal on an issuer's obligations when due. Credit default swaps provide
coverage for losses upon the occurrence of specified credit events set forth
therein. The Company's underwriting policy is to credit enhance obligations and
exposures that would otherwise be lower investment grades without the benefit of
the Company's enhancement, although on an exception basis, the Company will
consider underwriting high non-investment grade risks.

     Asset-backed obligations insured or reinsured by the Company are generally
issued in structured transactions backed by pools of assets of specified types,
such as residential mortgages, auto loans and other consumer receivables,
equipment leases and corporate debt obligations, having an ascertainable cash
flow or market value. Municipal obligations insured or reinsured consist mainly
of general or special obligations of state and local governments, supported by
the issuer's ability to charge fees for specified services or projects.
Corporate risk-based obligations which the Company has underwritten include
essential infrastructure projects and obligations backed by receivables from the
future sales of commodities and other specified services. Obligations guaranteed
or enhanced by the Company range in duration from a few years to 15 or more
years, and premiums are either received on an installment basis or up front.

     The Company has adopted written underwriting guidelines for the various
products and asset classes comprising the credit enhancement business, which
include single and aggregate risk limitations on specified exposures. A credit
committee including Bermuda-based executive officers of the Company provides
final underwriting approval for each transaction. Par insured and notional
amounts covered under the Company's guarantees and credit default swaps may be
up to $500 million or more for certain risks, and the underlying risks include
those of the Organization for Economic Cooperation and Development and emerging
market issuers and assets.

     The Company has also underwritten two transactions whereby substantial loss
reserves were assumed. In addition to the underwriting risks assumed, the
Company also has embedded exposure in these transactions to investment
performance return and ceded reserves. These transactions are actuarially
expected to be of long duration.

REINSURANCE CEDED

     In many cases, the risks assumed by the Company are reinsured with other
reinsurers. The benefits of ceding risks to other reinsurers include reducing
exposure on individual risks, protecting against catastrophic risks and
maintaining acceptable capital ratios. Reinsurance ceded does not legally
discharge the Company from its liabilities in respect of the risk being
reinsured. The following is a discussion of the types of reinsurance ceded by
the Company.

                                       5

     INSURANCE OPERATIONS

     The Company purchases a quota share and an excess of loss reinsurance
treaty to protect the general liability occurrence-notified business written.
Under the terms of the current quota share treaty, the Company cedes 20% of each
risk subject to a per risk maximum of $30 million. The aggregate maximum amount
recoverable under this treaty is 300% of the total premium ceded. Effective
April 1, 1999, the business covered by the treaty was extended to include
employment practices liability business. The treaty is placed with eight
reinsurers and no single reinsurer participates in excess of 20% of the program.
All reinsurers are rated by A.M. Best as A or better and all reinsurers, except
for one, are rated by S&P as BBB or better. The most significant reinsurers on
this program are Hannover Re, St. Paul Re and Cigna. These companies are rated
AA+, AA and BBB, respectively, by S&P, and have participations of 20%, 20% and
15%, respectively, on a reinsurance balance receivable and unpaid losses
recoverable balance of $192 million as of December 31, 1999.

     Under the terms of the excess of loss reinsurance treaty, the Company is
reinsured for $112.5 million excess of various per risk, aggregate and
quota-share retentions. The maximum amount recoverable under this treaty is $250
million. The treaty is placed with eighteen reinsurers including four Lloyd's
syndicates. No single reinsurer participates in excess of 20% of the program.
All reinsurers are rated by S&P as A or better, and all reinsurers, except for
one, are rated by A.M. Best as A or better. The most significant reinsurers on
this program are American Re, ERC Frankona and PMA Re. These companies are rated
AAA, AAA and A, respectively, by S&P, and have participations of 20%, 12.5% and
10%, respectively, on a reinsurance balance receivable and unpaid losses
recoverable balance of $38 million as of December 31, 1999.

     The Company also purchases a variable surplus treaty to protect the
property business written. Under the terms of the current treaty, the Company
can cede a maximum of 50% of each risk subject to a per risk maximum of $25
million. The maximum amount recoverable under this treaty is $50 million. The
treaty is placed with eight reinsurers and no single reinsurer participates in
excess of 20% of the program. All reinsurers are rated by A.M. Best as A or
better and by S&P as A- or better. The most significant reinsurers on this
program are ERC Frankona, PMA Re and St. Paul Re. These companies are rated AAA,
A and AA, respectively, by S&P, and have participations of 20%, 16% and 15%,
respectively, on a reinsurance balance receivable and unpaid losses recoverable
balance of $13 million as of December 31, 1999.

     The Company also purchases a quota share reinsurance treaty to protect the
general liability occurrence business. At December 31, 1999, there were no
losses under this treaty.

     REINSURANCE OPERATIONS

     Traditionally, the Company has purchased limited retrocession reinsurance
on its property business with covers primarily originating from common account
reinsurance on assumed business. Specific excess of loss protection is purchased
for the London and Singapore branch operations, and a corporate multi-year
program is purchased for its global property exposures. This protection gives
total limits in various layers and excess of varying attachment points according
to territorial exposure. The Company has co-reinsurance retentions within this
program. In August 1998, the Company placed $200 million of retrocessional
property catastrophe cover in a combination reinsurance and capital market swap
transaction which covered hurricane and earthquake exposure in the U.S. and its
territories and in the Caribbean. This cover was not renewed in 1999 and was
replaced by a second event cover of $300 million excess of a retention of
$500 million.

     The Company's casualty reinsurance program in 1999 covers multiple claims
arising from two or more risks in a single occurrence or event. Workers'
compensation business is reinsured at $195 million in excess of $5 million
retention for any one occurrence. An additional casualty contingency cover is
purchased for a total of $32 million excess of an initial retention of
$5 million, which gradually increases up to an additional $3 million should
gross losses exceed $30 million. In addition, the Company had coverage in 1999,
1998 and 1997 in the event that the accident year loss and loss expense ratio
exceeded a pre-determined amount. At December 31, 1999, the Company had a
reinsurance balance receivable and unpaid loss recoverable of $117 million due
from Hannover Re (Ireland) Ltd, which is rated A+ by A.M. Best.

                                       6
<PAGE>
     The Company had an intercompany stop loss agreement in place in 1999 under
which a subsidiary in the reinsurance segment was covered by a subsidiary in the
insurance segment for losses exceeding a specified loss ratio up to $100
million. The purpose of this agreement is to efficiently manage statutory
surplus levels across the Company.

     The 1998 casualty reinsurance program was similar to that of 1999. Workers'
compensation business is reinsured for $195 million in excess of $5 million
retention for any one occurrence. An additional casualty contingency cover is
purchased for a total of $25 million excess of an initial retention of
$5 million.

     The Company's 1997 casualty reinsurance program was substantially similar
to the 1998 program.

     The Company terminated two retrocessional programs effective January 1,
1997. Termination of these programs has resulted in an increase in net retention
levels for the years 1996 and prior. As the casualty book of business matures,
the increase in net retentions for these years may result in increased
volatility in future years to the extent the actual frequency and severity of
claims differs from management's current estimates. The Company believes its
exposure to such volatility is within acceptable levels.

     LLOYD'S OPERATIONS

     The Company's Lloyd's operations have historically purchased reinsurance to
protect the syndicates against extraordinary loss or loss involving one or more
underwriting classes. The amount purchased is determined with reference to the
syndicates' aggregate exposure and potential loss scenarios.

COMPETITION

     The worldwide property and casualty insurance and reinsurance industry 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. Some of the Company's competitors
possess significantly greater financial and other resources than the Company.
The Company generally competes on the basis of financial strength, coverage
terms, claims paying rating and reputation, price and customer service.

     See Industry Overview included in the "Management's Discussion of Financial
Condition and Results of Operations" for further discussion of current market
conditions.

UNDERWRITING AND MARKETING

     UNDERWRITING

     The insurance subsidiaries write liability and property 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 institutions 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 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 judgment 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 that group. Each industry group is reviewed
annually to take into account outstanding reported 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.

     The reinsurance subsidiaries employ 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 they anticipate

                                       7
<PAGE>
placing at risk. Underwriting opportunities presented are evaluated based upon a
number of factors including: the type and layer of risk to be assumed; actuarial
evaluation of premium adequacy; the cedent's underwriting and claims experience;
the cedent's financial condition and claims paying rating; exposure; and
experience with the cedent and the line of business to be underwritten. In
addition, the Company assesses a variety of other 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. On-site underwriting reviews are performed
where deemed necessary to determine the quality of a current or prospective
cedent's underwriting operation.

     For the property catastrophe reinsurance business, the Company 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 catastrophic losses in any geographic zone. The Company
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 the Company's zones is subject to periodic review and change. The
Company also generally seeks an attachment point for its property catastrophe
reinsurance anticipated to be high enough to produce a low frequency of loss.
The Company seeks to limit 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.

     The Company's Lloyd's operations underwrite a broad range of risks, and the
factors taken into consideration in the underwriting process vary between class
of business. An actuarial resource is available to underwriters to assist in the
review and rating of risks. Underwriters operate within agreed guidelines, which
establish maximum gross exposure by business area and geographic region. The
daily acceptance of risk is performed by the active underwriter, the class
underwriters and individuals with specific delegated authority. Underwriting
authority limits are agreed between the active underwriter, the class
underwriter and the managing agency's board of directors. Underwriters may
delegate underwriting authority on a contractual basis to individuals who are
approved and monitored. Brockbank Syndicates also participate on market
facilities where underwriting authority is delegated to the lead insurer.

     For the financial services business, the Company has adopted written
underwriting guidelines for the various products and asset classes comprising
the credit enhancement business, which include single and aggregate risk
limitations on specified exposures. A credit committee including Bermuda-based
executive officers of the Company provides final underwriting approval for each
transaction.

     As part of the underwriting process, all of the Company's insurance and
reinsurance underwriting operations evaluated potential exposures to claims,
losses and defense costs associated with Year 2000-related issues. Such claims,
losses and costs, to the extent that they materialize, could have a material
adverse affect on the Company's results of operations and financial condition.
No significant matters had been notified to the Company as of March 17, 2000.
For more information concerning the impact of Year 2000 issues on underwriting
results, see "Management's Discussion and Analysis of Results of Operations 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 brokers who receive from the insured or ceding company a brokerage commission
usually equal to a percentage of gross premiums. In general, subsidiaries of the
Company are not committed to accept business from any particular broker, and
brokers do not have the authority to bind any subsidiary of the Company, except
in the case where underwriting authority may be delegated to selected
administrators. These administrators are subject to a financial and operational
review prior to any delegation of authority and ongoing reviews are carried out
as necessary.

     During 1999, 1998 and 1997, approximately 21%, 34% and 35% of the Company's
consolidated gross written premiums were generated from or placed by Marsh &
McLennan Companies. During 1999, 1998 and 1997, approximately 13%, 19% and 18%
of the Company's consolidated gross written premiums were generated from or

                                       8
<PAGE>
placed by AON Corporation and its subsidiaries. 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 each of the
three years ended December 31, 1999, 1998 and 1997.

UNPAID LOSSES AND LOSS EXPENSES

     Certain aspects of the Company's business have loss experience
characterized as low frequency and high severity. This may result in volatility
in both the Company's results and operational cash flows.

     Loss reserves are established due to the significant periods of time that
may lapse between the occurrence, reporting and payment of a loss. To recognize
liabilities for unpaid losses, the Company estimates future amounts needed to
pay claims and related expenses with respect to insured events. 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 claim made against the Company's
subsidiaries.

     The method of establishing case reserves for reported claims differs
between the Company's operations. For the insurance operations, 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. A similar process is followed in the reinsurance and Lloyd's
operations when the Company is a lead underwriter. Other reinsurance and Lloyd's
business 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 payments are made.

     Most of the Company's incurred but not reported ("IBNR") loss reserves are
derived from casualty business. Casualty business generally has a longer tail
than the Company's other lines of business. IBNR is calculated in two steps.
First, case reserve development is estimated with the use of the loss
development factor method. Second, IBNR is estimated with a frequency and
severity approach. Since coverage is usually triggered when a notice is
submitted by the insured, IBNR losses exist only when claims with a loss notice
develop into the relevant layers of coverage. The method estimates 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.
However, even such actuarially sound methods, when coupled with the nature of
the risks written, can lead to subsequent adjustments to reserves that are both
significant and irregular.

     Several aspects of the Company's casualty insurance operations complicate
the actuarial reserving techniques for loss reserves as compared to other
insurance operations. 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 will be characterized by low frequency and high severity, limiting the
utility of claims experience of other insurers for similar claims. While
management believes it has made a reasonable estimate of ultimate losses, the
ultimate claims experience may not be as reliably predicted as may be the case
with other insurance operations, and there can be no assurance that losses and
loss expenses will not exceed the total reserves.

     Claims relating to property catastrophe and property risk excess treaties
will generally become known within approximately 18 to 24 months from the date
of occurrence. Conversely, claims on the casualty business develop on average 5
to 8 years from the date of occurrence. Claims under a significant number of
Lloyd's syndicate policies, with the exception of motor, will generally become
known within 36 months of the date of the occurrence. Motor claims not involving
personal injury will generally be known and paid within 12 months of the
occurrence.

                                       9
<PAGE>
     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 the prior estimates.

     The table below presents the development of unpaid loss and loss expense
reserves for 1989 through 1999. The top line of the table shows the liability,
net of reinsurance recoveries at the balance sheet date for each of the
indicated years. This represents the estimated amounts of net loss and loss
expenses arising in all prior years that are unpaid at the balance sheet date,
including IBNR. The upper portion shows the re-estimated amount of the
previously recorded reserve liability based on experience as of the end of each
succeeding year. The estimate changes as more information becomes known about
the frequency and severity of claims for individual years. The "Cumulative
Redundancy (Deficiency)" line represents the aggregate change in the successive
years with respect to that liability. The lower portion of the table reflects
the cumulative paid losses relating to these reserves. 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. See "Management's
Discussion and Analysis of Results of Operations and Financial
Condition - Cautionary Note Regarding Forward-Looking Statements."

     Losses incurred in 1999 grew significantly over 1998 for a number of
reasons. The Company acquired Mid Ocean and Brockbank in August 1998 and as a
consequence only recognized the effect of their operations for five months in
1998. Incurred losses for these entities were approximately $475 million in 1999
compared to $260 million in 1998. The Company was also affected by a number of
catastrophes in 1999 compared to 1998. The fourth quarter of 1999 generated
approximately $135 million of catastrophic losses to the Company, of which the
European storms in December account for the major part. The Company also
experienced a number of smaller catastrophe losses in 1999 that totaled
approximately $50 million. These losses included the Turkey earthquakes, the
Sydney hailstorms and the Oklahoma tornadoes. By comparison, the Company
incurred approximately $60 million in catastrophe losses relating to Hurricane
Georges and the SwissAir disaster in 1998. These losses were incurred in the
reinsurance operations.

     The Lloyd's operations experienced loss deterioration on the U.K. motor
business written by Brockbank, principally relating to its 1998 and 1999
underwriting years of approximately $20 million. The motor business was sold,
realizing a gain of approximately $40 million included in fee and other income
in 1999. The Company retains residual liability on this business.

     1999 incurred losses also include an increase of reinsurance loss reserves
of $95 million for NAC Re when it merged with the Company in June 1999. In
addition, the acquisition of Intercargo in June 1999 added approximately
$30 million to total incurred losses.

     The decrease in prior year incurred losses is driven primarily by the
Company's insurance liability excess of loss reserves. The basis for
establishing IBNR is unlike most insurance companies due to the lack of industry
data. Consequently, the Company estimates loss reserves through actuarial models
based upon its own experience. When the Company commenced writing this type of
business in 1986, limited data was available and the Company made its best
estimate of loss reserves at that time. Over time, the amount of data has
increased, providing a larger statistical base for estimating reserves.
Redundancies in prior year loss reserves have occurred where loss experience has
developed more favorably than expected.

     The increase in paid losses in 1999 and 1998 reflects the acquisition of
Mid Ocean and Brockbank in 1998. In addition, the nature of the Company's high
excess of loss liability and catastrophe business can result in loss payments
that are both irregular and significant. Similarly, 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
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

     Claims management for the insurance operations includes the review of
initial loss reports, creation of claims files, administration of a claims
database, generation of appropriate responses to claims reports, 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 management for the reinsurance operations includes the receipt of
loss notifications, the establishment of loss reserves and approval of loss
payments. Additionally, claims audits are conducted for both specific claims and
overall procedures at the offices of selected ceding companies.

     Claims in respect of business written by the Lloyd's operations are
primarily notified by various central market bureaus. Where a syndicate is a
"leading" syndicate on a Lloyd's policy, its underwriters and claims adjusters
will deal with the broker or insured on behalf of itself and the following
market for any particular claim. This may involve appointing attorneys or loss
adjusters. The claims bureaus and the leading syndicate advise movement in loss
reserves to all syndicates participating on the risk. A claims department can,
at times, adjust the case reserves it records from those advised by the bureaus.

INVESTMENTS

     Management oversees the Company's investment strategy, establishes
guidelines for the various external managers and implements investment decisions
with the assistance of such managers. The current investment strategy seeks to
maximize investment income through a high-quality, diversified portfolio whilst
focusing on preserving principal and maintaining liquidity. In this regard, at
December 31, 1999, the Company's fixed income investment portfolio includes U.S.
and non-U.S. sovereign government obligations, corporate bonds and other
securities, 60% of which were rated Aa or AA or better by a nationally
recognized rating agency. The Company also maintains a portfolio of equity
securities. Under current investment guidelines, up to 30% of the Company's
investment portfolio may be invested in equity securities. Insurance laws and
regulations impose restrictions on the Company's investments whereby certain
types of investments such as unquoted equity securities, investments in
affiliates, real estate and collateral loans may not qualify as admitted assets.
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 December 31,
1999, 1998 or 1997.

"Management's Discussion and Analysis of Results of Operations and Financial
Condition - Investment Operations".

EMPLOYEES

     At December 31, 1999, the Company and its subsidiaries employed
approximately 1,300 employees. None of these employees are represented by a
labor union, and the Company believes that its employee relations are excellent.

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
December 31, 1999, 1998 and 1997 was approximately $13 million, $9 million and
$7 million, respectively. 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 million, of which
$60 million has been spent through December 31, 1999. It is estimated that the
development will be completed sometime in 2001. See Note 11 to the Consolidated
Financial Statements for discussion of the Company's lease commitments.

ITEM 3. LEGAL PROCEEDINGS

     The Company, through its subsidiaries, in common with the insurance and
reinsurance industry in general, is subject to litigation and arbitration in the
normal course of its business. As of December 31, 1999, the Company was not a
party to any material litigation or arbitration 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.

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.

</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 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 December 31, 1999 was 700.

     (c) In 1999, four regular quarterly dividends were paid at $0.44 per share
to all shareholders of record on February 5, April 23, July 12 and
September 24.

     The Company paid four regular quarterly dividends in 1998, three of $0.40
per share to all shareholders of record on February 6, April 16, and July 15 and
one of $0.44 per share to all 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, capital
and surplus requirements of the Company's operating subsidiaries and regulatory
restrictions.

     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 laws and regulations of Bermuda,
the United States, and the United Kingdom, including those promulgated by the
Society of Lloyd's. See Note 18 to the Consolidated Financial Statements for
further discussion.

     (d) Rights to purchase Class A Ordinary Shares were distributed as a
dividend at the rate of one Right for each Class A ordinary share held of record
as of the close of business on October 31, 1998. Each Right entitles holders of
XL Class A ordinary shares to buy one ordinary share at an exercise price of
$350. The Rights would be exercisable, and would detach from the Class A
ordinary shares, only if a person or group were to acquire 20% or more of XL's
outstanding Class A ordinary shares, or were to announce a tender or exchange
offer that, if consummated, would result in a person or group beneficially
owning 20% or more of XL's Class A ordinary shares. Upon a person or group
without prior approval of the Board acquiring 20% or more of XL's Class A
ordinary shares, each Right would entitle

                                       17
<PAGE>
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 Rights.

1)  The loss and loss expense ratio is the calculated by dividing the losses and
    loss expenses incurred by the net premiums earned. In 1999, the loss and
    loss expense ratio excludes an increase to reserves of $95 million
    associated with the merger with NAC.

2)  Net income per share is based on the weighted average number of ordinary
    shares and ordinary share equivalents outstanding for each period as
    required by Statement of Financial Accounting Standard No. 128.

3)  All share and per share information has been retroactively restated to give
    effect to a one for one stock dividend paid to XL shareholders of record on
    July 26, 1996. Cash dividends per share have not been adjusted for the
    pooling effect of NAC.

4)  The underwriting expense ratio is the sum of acquisition expenses and
    operating expenses divided by net premiums earned. Operating expenses
    relating to the corporate segment have not been included for purposes of
    calculating the underwriting expense ratio.

5)  The combined ratio is the sum of the loss and loss expense ratio and the
    underwriting expense ratio. A combined ratio of under 100% indicates an
    underwriting profit and over 100% indicates an underwriting loss.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
AND FINANCIAL CONDITION

     The following is a discussion of the Company's results of operations and
financial condition. Prior period information presented is the combination of
the results formerly presented by XL Capital and NAC, as required for a business
combination accounted for by the pooling of interests method, which assumes NAC
had always been a part of the Company. It is also based upon the Company's new
fiscal year end of December 31. See Note 6 "Business Combinations" of the
audited Consolidated Financial Statements for further details. The Company's
results of operations and financial condition for 1998 were significantly
impacted by the acquisition of Mid Ocean in August 1998, which was accounted for
as a purchase business combination.

     This "Management's Discussion and Analysis of Results of Operations and
Financial Condition" contains forward-looking statements which involve inherent
risks and uncertainties. Statements that are not historical facts, including
statements about our beliefs and expectations, are forward looking-statements.
These statements are based upon current plans, estimates and expectations.
Actual results may differ materially from those projected in such
forward-looking statements, and therefore you should not place undue reliance on
them. See "--Cautionary Note Regarding Forward-Looking Statements" for a list of
factors that could cause actual results to differ materially from those

     This discussion and analysis should be read in conjunction with the audited
Consolidated Financial Statements and notes thereto presented under Item 8.

INDUSTRY OVERVIEW

     Abundant capacity and significant price competition continued to
characterize the property and casualty insurance and reinsurance industry during
1999. Excess capital and limited opportunities for growth in traditional markets
continued to generate merger and acquisition activity as companies attempt to
maintain or improve market share and performance. Perhaps more than ever, the
Company, together with the industry, faces a difficult challenge in generating
profitable growth.

     1999 was among the worst years for insured catastrophic losses. The
industry suffered losses from, amongst other events, the Sydney hailstorms, the
Oklahoma tornadoes, Hurricane Floyd and the European windstorms. Despite these
losses, premium rates in 1999 did not increase significantly.

RESULTS OF OPERATIONS

     The following table presents an after tax analysis of the Company's net
income for the years ended December 31, 1999, 1998 and 1997 (U.S. dollars in
thousands except per share amounts):

Earnings per share - diluted..............................     $3.62      $5.68      $7.74
</TABLE>

     Net income decreased in 1999 compared to 1998 as a result of a decrease in
both net operating income and net realized gains on investments. The decrease in
net operating income in 1999 from 1998 is due to a decrease in underwriting
income. The primary reason for this decrease is losses incurred by the Company
of $125 million after tax, or $0.97 per share, as a result of two major European
windstorms in December 1999. Net operating income increased in 1998 over 1997
due to the acquisition of Mid Ocean in 1998. Net income decreased in 1998
compared to 1997 as a result of a decrease in net realized gains on investments.

     Basic and diluted earnings per share decreased in 1999 over 1998 and in
1998 over 1997 due to both a decrease in net income, and, following the
acquisition of Mid Ocean, a net increase in the weighted average number of
shares issued and outstanding.

SEGMENTS

     The Company is organized into four underwriting segments - insurance,
reinsurance, Lloyd's syndicates and financial services - and a corporate
segment, which includes the investment operations of the Company. See Part 1 and
Item 8, Note 3 to the Consolidated Financial Statements for further details.

INSURANCE OPERATIONS

     The insurance business is written primarily by the following subsidiaries
of the Company: XL Insurance, XL Europe, XL Insurance Company of New York,
Greenwich Insurance, Indian Harbor Insurance, ECS and Intercargo. Insurance
business written includes general liability, other liability (including
directors and officers, professional and employment practices liability),
program business, property, marine, aviation, satellite and other product lines
(including U.S. Customs bonds, surety, political risk and specialty lines).

     The following table summarizes the underwriting profit (loss) for this
segment (U.S. dollars in thousands):

</TABLE>

NM=Not Meaningful

     The overall increase in net premiums earned in the insurance segment in
1999 over 1998 is primarily a result of an increase in gross premiums written in
the primary property, aviation and satellite, marine and other lines of business
by the Company's subsidiaries in the U.S. See Note 3 to the Consolidated
Financial Statements. Net

                                       20
<PAGE>
premiums earned in 1999 also reflect the purchase of Intercargo in May 1999, for
which approximately $33 million was earned from the date of purchase. Partially
offsetting this increase is a decrease in the general liability lines, where
there was a reduction in the amount of gross premiums written due to increased
competition. This decrease also accounts for the overall reduction in net
premiums earned in 1998 over 1997. High levels of competition continued,
particularly on a price basis and in coverage terms, although business retention
has remained in excess of 80% for the last three years. Generally, the Company's
response has been to move to higher attachment levels which result in lower
premiums as the Company moves further away from risk.

     There was a small increase in the net premiums earned in 1999 over 1998 in
the other liability business, which comprises mostly professional lines, despite
a decrease in the amount of gross premiums written in 1999 compared to 1998. The
increase in net premiums earned is primarily as a result of several tailored
programs written in 1998, which are earned over a period greater than one year.
There were also increases in net premiums earned in 1998 over 1997 in the
property, marine, energy, aviation and satellite lines of business, mainly in
the U.S. where there were expanded opportunities on existing accounts, as well
as new business.

     The source of fee and other income differs between 1999 and 1998. During
1998, the Company assisted in structuring a transaction that resulted in fee
income. These transactions tend to be irregular in nature and require an
investment of Company resources that are included in operating expenses. During
1999, the Company purchased ECS, which underwrites business on behalf of third
parties in exchange for commissions. This income will decline in the future as
ECS underwrites business on behalf of the Company.

     The changes in the loss and loss expenses, acquisition costs and operating
expenses as shown above are discussed below as part of the analysis of the
Company's underwriting ratios.

     The decrease in the underwriting profit in 1999 over 1998 in this segment
is due to higher loss and loss expense ratios in 1999 as reflected in the
underwriting expense ratios set forth below. The following table represents the
ratios for this segment for the three years ended December 31, 1999:

<TABLE>

Underwriting expense ratio..................................  29.4%   23.8%    21.6%
                                                              ----------------------
Combined ratio..............................................  96.1%   89.2%   103.7%
                                                              ----------------------
</TABLE>

     The increase in the loss ratio in 1999 over 1998 is the result of two
factors. The Company had an intercompany stop loss agreement in place in 1999
under which a subsidiary in the reinsurance segment was covered for losses
exceeding a specified loss ratio up to $100 million. The purpose of this
agreement is to efficiently manage statutory surplus levels across the Company.
As a result of catastrophic losses which occurred in 1999, the full amount of
losses of $100 million were included in the insurance segment and excluded from
the reinsurance segment. The loss and loss expense ratio would have been 45.2%
and the underwriting profit would have been $125 million had this stop loss
agreement not been in place. Offsetting this loss in 1999 and also causing the
decrease in the loss ratio in 1998 from 1997 was a reduction of insurance loss
reserves established on the Company's liability lines due to updated actuarially
determined reserve estimates. Due to the lack of industry data available, the
Company estimates loss reserves based upon its own experience. Over time, the
amount of data available has increased, providing a larger statistical base for
estimating reserves and loss experience has developed more favorably than
expected. In addition, reserves were reduced on specialty cover policies for the
years 1995 through 1997, which expired in 1998 and for which there was an
absence of expected losses on these policies.

     The increase in the expense ratio over each of the years presented is due
to both the changes in the product mix towards U.S. primary business which tends
to have higher acquisition costs, and the additional operating expenses incurred
by the Company in establishing its start up operations in the U.S. and new lines
of business.

                                       21

REINSURANCE OPERATIONS

     The reinsurance business is written by XL Mid Ocean Re, which writes
primarily property lines which are short-tail in nature, and NAC Re, which
primarily writes long-tail casualty business. Business written in this segment
includes casualty, property catastrophe, other property, marine, energy,
aviation and satellite and other lines, including political risk and specialty
lines.

     The following table summarizes the underwriting profit (loss) for this
segment (U.S. dollars in thousands):

</TABLE>

     The increase in net premiums earned in 1999 over 1998 is due to two
factors: (i) the acquisition of Mid Ocean in August 1998 which results in only
five months of net premiums earned included in 1998 compared to twelve months in
1999, and (ii) increases in gross premiums written and earned in the casualty
reinsurance business in 1999 resulting primarily from a relatively small number
of large reinsurance transactions. The increase in net premiums earned in 1998
over 1997 is primarily due to the acquisition of Mid Ocean. This increase was
partially offset by declines in net premiums earned on the casualty business in
1998 over 1997 due to increased market competition and pricing and the Company's
decision not to renew accounts that were deemed not to meet the Company's
profitability standards.

     Operating expenses increased in 1999 over 1998 and in 1998 over 1997 due to
the acquisition of Mid Ocean.

     The changes in the underwriting result in the reinsurance segment for each
of the three years ended December 31 are due to changes in the underwriting
ratios as illustrated below.

</TABLE>

     The increase in the loss ratio in this segment in 1999 over 1998 was due to
losses incurred by the Company from two major European windstorms which occurred
in December 1999, together with other insured catastrophes in Sydney and
Oklahoma, and from satellite losses earlier in the year. Property catastrophe
business has loss experience which is generally categorized as low frequency but
high severity in nature. This may result in volatility in the Company's
financial results for any fiscal year or quarter. Property catastrophe losses
generally are notified and paid within a short period of time from the covered
event. In addition, there was an increase in the loss ratio in 1999 over 1998 in
the casualty reinsurance business relating to reserve increases in accordance
with actuarial estimates, caused to a large extent by the deterioration in
premium rates. Actuarial assumptions are used to establish initial expected loss
ratios employed in the actuarial methodologies from which the reserve for loss
and loss expenses is derived. Such loss ratios are periodically adjusted to
reflect comparisons with actual claims development, inflation and other
considerations.

     Net losses incurred in this segment in 1999 reflect a reduction of
$100 million relating to an intercompany reinsurance agreement with another of
the Company's subsidiaries in the insurance segment. The loss and loss expense
ratio would have been 76.6% and the underwriting loss would have been $115
million had this stop loss

                                       22

agreement not been in place. Net losses incurred in 1999 also exclude an
adjustment to reserves of $95 million following the merger with NAC.

     The increase in the loss ratio in 1998 over 1997 is due to losses relating
to Hurricane Georges and SwissAir for approximately $60 million.

     The increase in the expense ratio in 1999 over 1998 is primarily due to an
increase in profit commission payable to cedents of proportional business
written by XL Mid Ocean Re. Profitability on some contracts written in earlier
underwriting years has increased relative to original estimates, with the
resulting increases in profit commissions payable.

     The Company's casualty business includes an element of asbestos and
environmental claims on business written prior to 1986. The Company's reserving
process includes a supplemental evaluation of claims liabilities from exposure
to asbestos and environmental claims, including related loss adjustment
expenses. However, the Company's loss and loss expense reserves for such
exposures, net of reinsurance, as of December 31, 1999, 1998, and 1997 is less
than 1% of its total reserves. A reconciliation of the Company's gross and net
liabilities for such exposures for the three years ending December 31, 1999 is
set forth in Note 7 of the Notes to Consolidated Financial Statements.

LLOYD'S SYNDICATES

     The Lloyd's operations comprise Brockbank and Denham, both of which were
acquired in 1998. Brockbank provides underwriting and other services to five
Lloyd's syndicates, two of which are dedicated corporate syndicates whose
capital is provided by the Company. During 1999, these dedicated corporate
syndicates wrote a range of specialty lines, primarily of insurance but also
reinsurance, in parallel with other syndicates managed by Brockbank. Denham
provides similar services to one corporate syndicate whose capital is partially
provided by the Company and which specializes in liability coverages.

</TABLE>

     The increase in 1999 over 1998 in this segment is a result of the Brockbank
acquisition in August 1998. In addition, results for Denham were not significant
in 1998.

     In 1999, fee and other income primarily relates to the sale by Brockbank of
its two motor insurance businesses, Admiral and Zenith, resulting in a gain of
$40.2 million. The Company expects there to be decreases in net premiums earned,
fee income and certain costs next year as a result of this sale. However, the
Company does not expect the overall profitability of its Lloyd's operations to
be significantly affected by such sales. Excluding the gain on sale, fee and
other income primarily relates to fees received from the management of Lloyd's
syndicates and profit commissions which are earned based upon the estimated
results of syndicates managed.

</TABLE>

     Losses incurred by the corporate syndicates of Brockbank attach at lower
levels and are therefore higher in frequency but lower in severity as compared
to the losses relating to the reinsurance and insurance segments of the Company.
The increase in the loss ratio in 1999 over 1998 is due to reserve increases
related to adverse development on the U.K. motor business prior to the sale for
which the Company still retains residual liability.

FINANCIAL SERVICES

     The financial services business includes premiums received from credit
enhancement by financial guaranty insurance and reinsurance policies and credit
default swaps written in respect of asset-backed, municipal and corporate risk
obligations. Fee income included in this segment is comprised primarily of
income received from the two loss reserve transactions that were underwritten in
1999. Premiums received in respect of credit default swap transactions are also
included as fee income and earned over the life of the policies.

     External investment professionals manage the Company's portfolio under the
direction of management.

     At December 31, 1999, total investments and cash, net of the payable for
investments purchased, were $9.1 billion, compared to $8.9 billion at
December 31, 1998. This increase includes the reinvestment of investment income
and realized gains, but is primarily due to the loss portfolio transfers
discussed further in "--Financial Condition and Liquidity". This increase was
net of any transfer of assets to limited investment partnerships, included in
investments in affiliates. As the Company's long-tail casualty business matures
over the next three to five years, it is possible that claims payments may
increase due to the additional exposure to events which occurred in prior years
but have not yet been paid. Funds available for investment may therefore be
reduced as compared to prior years due to such increased claims payments. The
Company's fixed income investments (including short-term investments and cash
equivalents) at December 31, 1999 represented approximately 88% of investments
available for sale and were managed by several independent investment managers
with different strategies. Of the fixed income securities, approximately 87% are
of investment grade, with 60% rated Aa or AA or better by a nationally
recognized rating agency.

     The payable for investments purchased was $622.3 million at December 31,
1999 and $633.2 million at December 31, 1998. The payable balance at any one
time is the result of a timing difference as it is the Company's policy to
account for its investments on a trade basis.

     The increase in investment income in 1999 over 1998 is primarily due to an
increase in the annualized effective yield on the portfolio. The increase in
investment income in 1998 over 1997 is due to an increase in the average asset
base, primarily due to the merger with Mid Ocean in August 1998 and the
Company's positive operational cash flow. The investment income from the asset
accumulation business assets transferred did not have a significant impact due
to the timing of the transfers to the Company which occurred in the third and
fourth quarters of 1999.

     Net realized gains in 1999 and 1998 reflect the strong performance of the
equity market. In 1998, equity gains of $150.0 million were realized as some of
the Company's equity managers locked in gains where they felt valuations had
reached their targets. However, 1999 equity gains were offset by declining fixed
income markets, which had been strong throughout most of 1998. Due to declining
interest rates combined with widening spreads in the corporate and mortgage
markets, the fixed income sector allowed the Company opportunities to increase
the yield on its investment in 1999. As a result, the Company's investment
managers will continue to pursue a total return strategy to take advantage of
the higher yields. During 1997, both the fixed income and equity portfolios were
restructured, resulting in the 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 $11.3 million and $23.2 million for the
years ended December 31, 1999 and 1998, respectively.

</TABLE>

NM=Not Meaningful

     The decrease in equity in net income of affiliates in 1999 over 1998 and
1998 over 1997 is due to Mid Ocean. Partially offsetting the decrease in 1999
are earnings from new investments made in limited investment partnerships by the
Company during 1999. In 1998, seven months of earnings from the Company's equity
position in Mid Ocean were recognized, which ended in August 1998 upon the
acquisition of the balance of the outstanding Mid Ocean shares. A full year's
equity earnings from Mid Ocean were included in 1997.

     The increase in the amortization of intangible assets in 1999 over 1998 and
1998 over 1997 mainly relates to the goodwill arising from the Mid Ocean
acquisition in 1998. In 1999, there is also additional goodwill amortization of
approximately $4.0 million arising from acquisitions of ECS and Intercargo.

     Operating expenses in 1999 include $45.3 million of one-time charges
related to the merger with NAC. In 1998, they include $17.5 million of one-time
charges associated with the merger with Mid Ocean. Other increases are due to
the increase in the corporate infrastructure necessary to support the growing
worldwide operations of the Company.

     Increases in interest expense in 1999 over 1998 and 1998 over 1997 is due
to the increase in the average long-term debt outstanding during the each of the
years. In 1999, this was used to finance the acquisitions of ECS and Intercargo,
and in both 1999 and 1998, the repurchase of shares.

     The changes in the income tax expense of the Company principally reflect
the decline in the profitability of the U.S. operations for each year. In 1999,
a deterioration of the casualty book for business underwritten prior to the
merger with NAC resulted in a pre-tax net loss for U.S. operations, generating
an income tax benefit for the year. See Note 17 to the Consolidated Financial
Statements.

FINANCIAL CONDITION AND LIQUIDITY

     As a holding company, the Company's assets consist primarily of its
investments in 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 and regulations of Bermuda, the United States, Ireland and the United
Kingdom, including those promulgated by the Society of Lloyd's which are
described more fully in Note 18 to the Consolidated Financial Statements. No
assurance can be given that the Company or its subsidiaries will be permitted to
pay dividends in the future. The Company's shareholders' equity at December 31,
1999 was $5.6 billion, of which $3.1 billion was retained earnings.

     Certain aspects of the Company's business are characterized as having low
frequency and high severity exposures. This may result in volatility in both the
Company's results and operational cash flows. However, the Company continues to
generate significant positive cash flow from operating activities.

                                       26
<PAGE>
     In 1999, 1998 and 1997, the total amount of net losses paid by the Company
was $1,093.5 million, $730.9 million and $330.9 million, respectively. The
increase is primarily due to the acquisition of Mid Ocean in August 1998.

     The Company establishes reserves to provide for estimated 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 larger claims. 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 any
multi-year policies at the time contracts are written.

     In 1999, the Company completed the purchase of Intercargo and ECS for a
total of $222.8 million in cash. Both of these transactions are accounted for
under the purchase method of accounting, and resulted in goodwill of
$159.6 million. These transactions were financed in part through bank borrowings
and internal funds.

     During 1999, the Company redistributed assets from investments available
for sale and cash for the following investments:

     (1) The Company made minority investments in Highfields Capital Management
LP and MKP Capital Management LP and into the funds they manage totaling
$281.2 million.

     (2) The Company invested $97.0 million in a joint venture with Les
Mutuelles du Mans Assurances Group to form a new French reinsurance company, Le
Mans Re.

     (3) The Company invested a further $91.0 million in limited partnerships
and other investments.

     These above investments account for the increase in investments in
affiliates and other investments.

     The Company assumed two loss portfolio transfers during the second half of
the year which are accounted for on a deposit basis. These reserves are included
in deposit liabilities and policy benefit reserves with the corresponding assets
held in investments available for sale.

     The Company has had several stock repurchase programs as part of its
capital management. On January 22, 1999, the Board of Directors discontinued the
Company's existing program with $148.8 million remaining and replaced it with an
authorization to repurchase $500 million. During the first six months of 1999,
the Company purchased 2.1 million shares at a cost of $126.8 million. In
June 1999, the Board of Directors rescinded the Company's share repurchase
program. On January 9, 2000 the Board of Directors authorized the repurchase of
shares up to $500 million. The repurchase of shares was announced in conjunction
with a small dividend increase of $0.04 per share per annum as part of the
Company's capital management strategy. The Company has purchased 3.7 million
shares up to March 17, 2000 at a cost of $165.8 million or $44.76 per share.

     As at December 31, 1999, the Company had bank and loan facilities available
from a variety of sources, including commercial banks, totaling $2.36 billion
comprising 364-day facilities, 5-year facilities, notes payable and other loans
and letter of credit facilities. Debt and notes outstanding at December 31, 1999
were $410.7 million and letters of credit outstanding were $891.6 million.
Letters of credit issued and outstanding, 66% of which were collateralized by
the Company's investment portfolio, primarily support U.S. non-admitted business
and the Company's Lloyd's capital requirements.

     During 1999 and 1998, borrowings under these facilities were $329 million
and $655 million, respectively, and repayments under the facilities were
$340 million and $495 million, respectively. The borrowings in 1999

                                       27
<PAGE>
facilitated the repurchase of shares and the purchase of Intercargo and ECS. In
1998, borrowings include $300 million to fund the cash election available to
shareholders in connection with the Mid Ocean merger. Included in the 1998 notes
payable and debt was $100 million 5.25% Convertible Subordinate Debentures due
2002, which were converted in June 1999 by the issue of 1.8 million shares out
of treasury. Additional borrowings in 1998 were made to fund the Company's U.S.
operations. The total pre-tax interest expense on notes and debt outstanding
during the year ended December 31, 1999 and 1998 was $37.4 million and
$33.4 million, respectively. Associated with the Company's bank and loan
commitments are various loan covenants with which the Company was in compliance
throughout the period. See Note 10 to the Consolidated Financial Statements for
further details.

YEAR 2000 ISSUES

     There was no significant impact of Year 2000 issues on the Company's
technology systems. Total costs incurred by the Company in ensuring its
technology systems were compliant through December 31, 1999 were not
significant. The Company did not experience any significant disruption due to
the impact of Year 2000 issues on its service providers.

     The Company is exposed to risks associated with Year 2000 issues based upon
the underwriting exposures that it assumes. All insurance and reinsurance
subsidiaries of the Company examined the potential exposure to Year 2000-related
risks associated with the coverages that they provided. In some instances, Year
2000-related risks were 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 apparent lack of
significant Year 2000-related losses, the Company does not expect to have a
material exposure to Year 2000-related coverage claims. See generally
"--Cautionary Note Regarding Forward-Looking Statements".

FINANCIAL RISK MANAGEMENT

     The Company is exposed to various market risks, including changes in
interest rates and foreign currency exchange rates. Market risk is the potential
loss arising from adverse changes in interest rates and foreign currency
exchange rates. The Company manages its market risks based on guidelines
established by management. The Company enters into derivatives and other
financial instruments primarily for risk management purposes.

     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 analysis methods used by the Company to assess and
mitigate risk should not be considered projections of future events of losses.
See generally "--Cautionary Note Regarding Forward-Looking Statements".

     The Company's investment portfolio consists of fixed income and equity
securities, denominated in both U.S. and foreign 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 5.8% or $438 million on the
Company's fixed income portfolio as of December 31, 1999.

     In evaluating the impact of price changes of the equity portfolio, a 10%
change in equity prices would affect total return by approximately
$114 million.

     The Company has short-term debt and long-term debt outstanding. Interest
rates on short-term debt are LIBOR based. Accordingly, any changes in interest
rates will affect interest expense.

FOREIGN CURRENCY RISK MANAGEMENT

     The Company uses foreign exchange contracts to manage its exposure to the
effects of fluctuating foreign currencies on the value of its foreign currency
fixed maturities and equity investments. These contracts are not designated as
specific hedges for financial reporting purposes and therefore realized and
unrealized gains and losses on them are recorded in income 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 may not
be entered into. At December 31, 1999, forward foreign exchange contracts with
notional principal amounts totaling $339.3 million were outstanding. The fair
value of these contracts as at December 31, 1999 was $341.1 million with
unrealized gains of $1.8 million. Losses of $2.7 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
December 31, 1999 would have resulted in approximately $34.6 million in
unrealized gains and $33.7 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 foreign currency
investments. These contracts are not designated as specific hedges, 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 December 31, 1999, the value of such contracts outstanding was not
significant.

     The Company attempts to hedge directly the foreign currency exposure of a
portion of its foreign currency fixed maturity investments using forward foreign
exchange contracts that generally have maturities of three months or less and
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
December 31, 1999, the Company had, as hedges, foreign exchange contracts for
the sale of $94.0 million and the purchase of $7.5 million of foreign currencies
at fixed rates, primarily Euros (49% of net contract value), British pounds
(18%) and New Zealand Dollars (16%). The market value of fixed maturities
denominated in foreign currencies that were hedged and held by the Company as at
December 31, 1999 was $85.2 million.

     Unrealized foreign exchange gains and losses on foreign exchange contracts
hedging foreign currency fixed maturity investments are deferred and included as
a component of shareholders' equity. As at December 31, 1999, unrealized
deferred losses amounted to $2.0 million and were offset by corresponding
increases 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 December 31, 1999,
realized deferred losses amounted to $0.5 million.

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 December 31, 1999, the portfolio held
$121.9 million in exposure to S&P 500 Index futures and underlying assets of
$122.0 million. Based on this value, a 10% increase or decrease in the price of
these futures would have resulted in exposure of $134.1 million and
$109.7 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
December 31, 1999, net realized gains from index futures totaled $11.3 million
as a result of the 19.5% 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 December 31, 1999, bond
and stock index futures outstanding were $241.1 million with underlying
investments having a market value of $2.5 billion (all 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 $24.1 million, respectively.

RECENT ACCOUNTING PRONOUNCEMENTS

     See Note 2 to the Consolidated Financial Statements for a discussion on
recent accounting pronouncements.

CURRENT OUTLOOK

     The Company believes competition in the property casualty insurance and
reinsurance industry will continue to be strong in 2000, exerting pressure on
rates in general across many product lines. Although the Company believes some
opportunities will exist in 2000 for growth in selected product lines, no
assurances can be made that growth in these lines will be sufficient to offset
the competitive pressures affecting the majority of the Company's 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; (iv) developments in the world's financial and
capital markets which adversely affect the performance of the Company's
investments; (v) changes in regulation or tax laws applicable to the Company,
its subsidiaries, brokers or customers; (vi) acceptance of the Company's
products and services, including new products and services; (vii) changes in the
availability, cost or quality of reinsurance; (viii) changes in the distribution
or placement of risks due to increased consolidation of insurance and
reinsurance brokers; (ix) the impact of the Year 2000-related issues on the
Company's underwriting exposures; (x) loss of key personnel; (xi) the effects of
mergers, acquisitions and divestitures; (xii) changes in rating agency policies
or practices; (xiii) changes in accounting policies or practices; and
(xiv) changes in general economic conditions, including inflation, foreign
currency exchange rates and other factors. The foregoing review of important
factors should not be construed as exhaustive and should be read in conjunction
with the other cautionary statements that are included herein or elsewhere. The
Company undertakes no obligation to publicly update or revise any
forward-looking statement, whether as a result of new information, future
developments or otherwise.

              For the Years Ended December 31 1999, 1998 and 1997

                          (U.S. dollars in thousands)

1. HISTORY

     XL Capital Ltd (sometimes referred to as 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, in connection with EXEL's merger with Mid Ocean Limited, a
Cayman Islands corporation. The merger was accounted for as a purchase under
U.S. generally accepted accounting principles ("GAAP") and as such, results of
operations of Mid Ocean are included from August 1, 1998, the effective date of
the merger. In the merger, all of the shares of EXEL and Mid Ocean were
exchanged for shares in the Company according to two schemes of arrangement
under Cayman Islands law. 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 Capital 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.

     In 1999, XL Capital merged with NAC Re Corp, a Delaware corporation. The
merger has been accounted for as a "pooling of interests" under U.S. GAAP. Under
pooling of interests accounting, it is assumed that XL Capital and NAC have been
merged from the date of incorporation of the Company, and accordingly, all prior
period information contained in this document includes the results of NAC. NAC
was organized in 1985 and, through its subsidiaries, writes property and
casualty insurance and reinsurance in the U.S., Canada and Europe. Subsequent to
the merger agreement, XL Capital amended its financial year from November 30 to
December 31 as a conforming pooling adjustment and to facilitate year end
reporting for its subsidiaries.

     XL Insurance, a company organized under the laws of Bermuda, and its
subsidiaries are the Company's principal insurance subsidiaries. XL Insurance
was formed in 1986 in response to a shortage of high excess liability coverage
for Fortune 500 companies in the U.S. In 1990, XL Insurance formed XL Europe, an
insurance company organized under the laws of Ireland to serve European clients
and, in 1998, formed two companies now known as XL Insurance Company of New York
and XL Capital Assurance.

     XL Mid Ocean Reinsurance is organized under the laws of Bermuda. On
August 7, 1998, XL Mid Ocean Re was formed through the merger of XL Global
Reinsurance and Mid Ocean Re. XL Global Re was formed in November 1997 through
the merger of XL Reinsurance and Global Capital Reinsurance following EXEL's
acquisition of GCR Holdings Limited, a Cayman Islands holding company, on
June 12, 1997. XL Reinsurance commenced operations on December 1, 1995 to write
specialty reinsurance business. Mid Ocean Re and Global Capital Re 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.

     The Company further expanded into the U.S. in 1999 by completing the
acquisition of both Intercargo Corporation and ECS, Inc. Intercargo, through its
subsidiaries, underwrites specialty insurance products for companies engaged in
international trade, including U.S. Customs bonds and marine cargo insurance.
ECS is an underwriting manager, which specializes in environmental insurance
coverages and risk management services.

     The Brockbank Group was acquired through the merger with Mid Ocean.
Brockbank is a company organized under the laws of the United Kingdom and is a
leading Lloyd's managing agency which provides underwriting and similar services
to five Lloyd's syndicates. Two of these syndicates are dedicated 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 on
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. As a managing agency, Brockbank receives
fees

1. HISTORY (CONTINUED)
and commissions in respect of underwriting services it provides to syndicates.
In the fourth quarter of 1999, Brockbank sold its two motor insurance
businesses, Admiral and Zenith. The Company expects there to be decreases in
premiums, fee income and certain costs, however it does not expect the overall
profitability of its Lloyd's operations to be materially affected by such sales.

     Denham Syndicate Management Limited was acquired by NAC during 1998 and it
also provides underwriting and similar services to one corporate syndicate,
whose capital is partially provided by the Company. This syndicate writes a
specialized book of international business, concentrating on long-tail casualty
and non-marine physical damage.

     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 that possess expertise in lines of business that the Company
wishes to write. 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 and related
risk management. In July 1999, the Company entered into a joint venture with Les
Mutuelles du Mans Assurances Group to form a new French reinsurance company, Le
Mans Re. The Company owns a 49% shareholding in the new company, which
underwrites a worldwide portfolio comprising all classes of non-life reinsurance
business together with a selective portfolio of life reinsurance business.

     In 1999, the Company made strategic minority investments in two investment
management firms. The Company acquired minority investments in Highfields
Capital Management L.P., a global equity investment firm, and MKP Capital
Management, a New York-based fixed income investment manager specializing in
mortgage-backed securities.

     In 1998, the Company entered into a joint venture with FSA Holdings Ltd to
write financial guaranty insurance and reinsurance. 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 Reeve Court Insurance, a Bermuda company organized as a
joint venture with such company's management for the purpose of providing life
insurance to high net worth individuals in 1998.

     In 1997, the Company acquired a 75% holding in Latin America Re, a Bermuda
reinsurance company.

     The Company formed Sovereign Risk Insurance as a joint venture in 1997.
Sovereign is a Bermuda-based managing general agency that writes political risk
insurance on a subscription basis on behalf of its shareholders.

     In 1996, the Company acquired approximately 30% of Pareto Partners, a firm
that specializes in foreign currency management and related services.

2. 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 U.S.
generally accepted accounting principles ("GAAP"). They include the merger with
NAC, which occurred in June 1999, and which has been accounted for as a "pooling
of interests" under U.S. GAAP. They are also based upon the Company's new fiscal
year end of December 31. Results of operations, statements of position and cash
flows include NAC as though it had always been a part of the Company. All
material intercompany accounts and transactions have been eliminated. The
preparation of financial statements in conformity with GAAP 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.

     (B) PREMIUMS AND ACQUISITION COSTS

     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 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 and
unearned premiums are presented after deductions for reinsurance ceded to other
insurance companies.

     Financial guaranty insurance premiums are earned over the life of the
exposure, and certain transactions such as installment premiums are not
recognized as premiums written until the premium is received.

     Acquisition costs, which vary with and are primarily related to the
acquisition of policies, primarily commissions paid to brokers, are deferred and
amortized over the period the premiums are earned. Future earned premiums and
the anticipated losses, investment income 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 are expensed and
the commissions recorded thereon are earned on a monthly pro-rata basis over the
period the reinsurance coverage is provided. Amounts recoverable from reinsurers
are estimated in a manner consistent with the claim liability associated with
the reinsured policy. Provision is made for estimated unrecoverable reinsurance.

     (D) INVESTMENTS

     Investments are considered 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, net of tax, is included
in accumulated other comprehensive income. Any unrealized depreciation in value
considered by management to be other than temporary is charged to income in the
period that it is determined.

                          (U.S. dollars in thousands)

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     Short-term investments comprise investments with a maturity equal to or
greater than 90 days but less than one year. Equity securities include
investments in open end mutual funds. 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 carried at fair value,
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) CASH EQUIVALENTS

     Cash equivalents include fixed interest deposits placed with a maturity of
under 90 days when purchased.

     (F) FOREIGN CURRENCY TRANSLATION

     Assets and liabilities of foreign operations whose functional currency is
other than the U.S. dollar are translated at year end exchange rates. Revenue
and expenses of such foreign operations are translated at average exchange rates
during the year. The effect of the translation adjustments for foreign
operations is recorded, net of applicable deferred income taxes, as a separate
component of accumulated other comprehensive income in shareholders' equity.

     Other monetary assets and liabilities denominated in foreign currencies are
translated at the exchange rate in effect at the balance sheet date with the
resulting foreign exchange gains and losses recognized in income, unless the
foreign currency exposure is directly hedged as discussed above. Revenue and
expense transactions are translated at the average exchange rates prevailing
during the year.

     (G) INVESTMENTS IN AFFILIATES

     Investments in which the Company has significant influence over the
operations of its affiliates are carried under the equity method of accounting.
Under this method, the Company records its proportionate share of income or loss
for such investments in its results of operations.

     (H) OTHER INVESTMENTS

     The Company accounts for its other investments on a cost basis as it has no
significant influence over these entities. Investments are written down to their
realizable value where management considers there is a permanent decrease in
value. Income is recorded when received.

     (I) 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 determined
that an impairment exists, the excess of the unamortized balance over the fair
value of the intangible asset will be charged to earnings at that time.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     (J) 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
based on amounts reported from insured or ceding companies and consultation with
independent legal counsel, and represents the estimated ultimate cost of events
or conditions that have been reported to or specifically identified by the
Company. Certain workers' compensation case reserves are considered fixed and
determinable and are subject to tabular reserving. Such tabular reserves are
discounted using an interest rate of 7%.

     The Company recognizes as a component of loss reserves, the loss experience
accounts of policyholders for policies written on a multi-year basis where
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 the Company was 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 industries.

     Management believes that the reserves for unpaid losses and loss expenses
are sufficient to pay any losses that fall within coverages assumed by the
Company. However, there can be no assurance that losses will not exceed the
Company's total reserves. The methodology of estimating loss reserves 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.

     (K) DEPOSIT LIABILITIES AND POLICY BENEFIT RESERVES

     Short duration contracts entered into by the Company which are not deemed
to transfer significant underwriting and/or timing risk are accounted for as
deposits, whereby liabilities are recorded for the same amount of premium
received. The Company will periodically re-assess the amount of the deposit
liabilities. Changes are recorded in the period they are determined as either
interest income where the contract does not transfer underwriting risk, or net
losses and loss expenses incurred where the contract does not transfer
significant timing risk.

     Policy benefit reserves relate to long duration contracts written by the
Company which do not transfer significant mortality or morbidity risks, and are
accounted for as deposits, and liabilities for estimated future policy benefits
are established at the time such funds are received.

     (L) INCOME TAXES

     The Company utilizes the liability method of accounting for income taxes.
Under the liability method, deferred income taxes reflect the net tax effect of
temporary differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes. A
valuation allowance is established for any portion of a deferred tax asset that
management believes will not be realized.

     (M) STOCK PLANS

     The Company accounts for stock compensation plans in accordance with
Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued
to Employees". Accordingly, compensation expense for stock option

grants and stock appreciation rights is recognized to the extent that the fair
value of the stock exceeds the exercise price of the option at the measurement
date.

     (N) PER SHARE DATA

     Basic earnings per share is based on weighted average common shares
outstanding and excludes any dilutive effects of options and convertible
securities. Diluted earnings per share assumes the conversion of dilutive
convertible securities and the exercise of all dilutive stock options.

     (O) FAIR VALUE OF FINANCIAL INSTRUMENTS

     Fair values of certain assets and liabilities are based on published market
values, if available, or estimates of fair value of similar issues. Fair values
are reported in Notes 4 and 10.

     (P) RECENT ACCOUNTING PRONOUNCEMENTS

     The Financial Accounting Standards Board issued Statement ("SFAS")
No. 133, "Accounting for Derivative Instruments and Hedging Activities," which
is required to be adopted in years beginning after June 15, 2000. The Company
has not yet completed its assessment of the effect of the adoption of this
standard on results of operations, financial condition or liquidity, but
believes it will not be significant.

3. SEGMENT INFORMATION

     The Company is organized into four underwriting segments - insurance,
reinsurance, Lloyd's syndicates and financial services - in addition to a
corporate segment that includes the investment operations of the Company.
Certain business written by the Company has loss experience characterized as low
frequency and high severity. This may result in volatility in both the Company's
results and operational cash flows.

     INSURANCE OPERATIONS

     The insurance business is written primarily by the following: XL Insurance,
XL Europe, XL Insurance Company of New York, Greenwich Insurance, Indian Harbor
Insurance, ECS and Intercargo. Business written includes general liability,
other liability including directors and officers, professional and employment
practices liability, property, program business, marine, aviation, satellite and
other product lines including U.S. Customs bonds, surety, political risk and
specialty lines.

     REINSURANCE OPERATIONS

     The Company's reinsurance business is primarily written by NAC Re and XL
Mid Ocean Re. Business written includes treaty and facultative reinsurance to
primary insurers of casualty risks, principally: general liability; professional
liability; automobile and workers' compensation; commercial and personal
property risks; specialty risks including fidelity and surety and ocean marine;
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. The Company endeavors to manage its exposures to catastrophic
events by limiting the amount of its exposure in each geographic zone worldwide
and requires that its property catastrophe contracts provide for aggregate
limits and varying attachment points.

3. SEGMENT INFORMATION (CONTINUED)
     LLOYD'S SYNDICATES

     The Lloyd's operations are comprised of Brockbank and Denham. Corporate
syndicates write property, marine and energy, aviation and satellite, motor,
professional indemnity, liability coverage and other specialty lines, primarily
of insurance but also reinsurance. Effective January 1, 2000, the Company
discontinued writing direct motor business.

     FINANCIAL SERVICES

     Financial services premiums are written by XL Insurance through XL Capital
Products. Business written includes insurance and reinsurance solutions for
complex financial risks. These include financial insurance and reinsurance,
credit enhancement swaps and other collateralized transactions. 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 approached this market on a "net-line" basis, but may
cede a portion of some policies to third parties from time to time. In 1999, the
Company also commenced assuming large loss portfolios as part of its new asset
accumulation strategy.

     The Company evaluates performance of each segment based on underwriting
profit or loss. Other items of revenue and expenditure of the Company are not
evaluated at the segment level. In addition, management does not consider the
allocation of assets by segment. The following is an analysis of the
underwriting profit or loss by segment together with a reconciliation of
underwriting profit or loss to net income:

     At December 31, 1999 and 1998, approximately $89.4 million and
$92.0 million, respectively, of securities were on deposit with various U.S.
state or government insurance departments in order to comply with insurance
regulations.

     Through its subsidiaries, the Company has two facilities available for the
issuance of letters of credit collateralized against the Company's investment
portfolio, which were up to a value of $791.4 million at December 31, 1999. At
December 31, 1999 and 1998, approximately $591.0 million and $348.9 million,
respectively, of letters of credit were issued and outstanding under these
facilities.

     Included in cash and invested assets at December 31, 1999 and 1998 are
approximately $16.6 million and $22.4 million, respectively, of assets held in a
"holding company" escrow account arising from a tax allocation agreement between
certain of the Company's U.S. subsidiaries.

5. INVESTMENTS IN AFFILIATES

     The following investments are accounted for on the equity basis:

     In 1999, the Company acquired minority investments in Highfields Capital
Management L.P., a global equity investment firm, and MKP Capital Management, a
New York-based fixed income investment manager specializing in mortgage-backed
securities, and invested in the closed end funds they manage.

     In 1999, the Company signed a joint venture agreement with Les Mutuelles du
Mans Assurances Group to form a new French reinsurance company, Le Mans Re. The
Company owns a 49% shareholding in the new company, which underwrites a
worldwide portfolio comprising all classes of non-life reinsurance business
together with a selective portfolio of life reinsurance business.

     The Company owned 27.9% of the issued shares of Risk Capital Holdings as at
December 31, 1999 and 1998. Risk Capital provides reinsurance and other forms of
capital for insurance companies with capital needs that cannot be met by
reinsurance alone. Subsequent to year end, this investment was sold. See
Note 20 for further discussion.

     The Company owns 30% of Pareto Partners, a partnership engaged in the
business of providing investment advisory and discretionary management services.

At December 31, 1999, the Company owned 20% of FSA International.

     The Company owned approximately 25% of Mid Ocean until July 31, 1998.
Subsequent to this date, Mid Ocean was acquired by the Company and has been
consolidated.

6. BUSINESS COMBINATIONS AND CHANGE IN FISCAL YEAR END

     (A) NAC RE CORP.

     On June 18, 1999, the Company merged with NAC in an all-stock transaction.
Shareholders of NAC received 0.915 Company shares for each NAC share in a tax
free exchange. Approximately 16.9 million of the Company's Class A ordinary
shares were issued in this transaction. The merger transaction has been
accounted for as a pooling of interests under U.S. GAAP.

     Following the merger, the Company changed its fiscal year end from
November 30 to December 31 as a conforming pooling adjustment. No adjustments
were necessary to conform NAC's accounting policies, although certain
reclassifications were made to the NAC financial statements to conform to the
Company's presentation.

     The following table presents a reconciliation of the total revenues, net
income, and earnings per share of the Company as previously reported as adjusted
for the change in fiscal year end, combined with the results of NAC:

     In 1999, the Company acquired ECS, an underwriting manager which
specializes in environmental insurance coverages and risk management services.
Commencing January 2000, ECS will underwrite policies on behalf of the Company's
insurance and reinsurance subsidiaries.

     In 1999, the Company acquired Intercargo, which through its subsidiaries,
underwrites specialty insurance products for companies engaged in international
trade, including U.S. Customs bonds and marine cargo insurance.

     The Intercargo and ECS acquisitions have been accounted for under the
purchase method of accounting. The combined purchase price was $222.8 million
and the resulting goodwill of $159.6 million is being amortized over 20 years.

</TABLE>

     Business written by the Company has loss experience characterized as low
frequency but high severity in nature. This may result in volatility in the
Company's financial results. Actuarial assumptions used to establish the
liability for losses and loss expenses are periodically adjusted to reflect
comparisons to actual loss and loss expense development, inflation and other
considerations.

     Several aspects of the Company's casualty insurance operations complicate
the actuarial reserving techniques for loss reserves as compared to other
insurance operations. 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 insureds for similar claims.
While management believes it has made a reasonable estimate of ultimate losses,
the ultimate claims experience may not be as reliably predicted as may be the
case with other insurance operations, and there can be no assurance that losses
and loss expenses will not exceed the total reserves.

     Losses incurred in 1999 grew significantly over 1998 for a number of
reasons. The Company acquired Mid Ocean and Brockbank in August 1998 and
consequently, only recognized the effect of their operations for five months in
1998. Incurred losses for these entities were approximately $475 million in 1999
compared to $260 million in 1998. The Company was also affected by a number of
catastrophes in 1999 compared to 1998. The fourth

7. LOSSES AND LOSS EXPENSES (CONTINUED)
quarter of 1999 generated approximately $135 million of catastrophic losses to
the Company, of which the European storms in December account for the major
part. The Company also experienced a number of smaller catastrophe losses in
1999 that totaled approximately $50 million. These losses included the Turkey
earthquakes, the Sydney hailstorms and the Oklahoma tornadoes. By comparison,
the Company incurred approximately $60 million in catastrophe losses relating to
Hurricane Georges and the SwissAir disaster in 1998. These losses were incurred
in the reinsurance operations.

     The Lloyd's operations experienced loss deterioration on the U.K. motor
business written by Brockbank, principally relating to its 1999 and 1998
underwriting years of approximately $20 million. 1999 incurred losses also
include an increase to reinsurance loss reserves of $95 million for NAC when it
merged with the Company in June 1999. In addition, the acquisition of Intercargo
in June 1999 also added approximately $30 million to total incurred losses.

     The decrease in prior year incurred losses is driven primarily by the
Company's insurance liability excess of loss reserves. The basis for
establishing IBNR is unlike most insurance companies due to the lack of industry
data. Consequently, the Company estimates loss reserves through actuarial models
based upon its own experience. When the Company commenced writing this type of
business in 1986, limited data was available and the Company made its best
estimate of loss reserves at that time. Over time, the amount of data has
increased, providing a larger statistical base for estimating reserves.
Redundancies in prior year loss reserves have occurred where loss experience has
developed more favorably than expected.

     The increase in paid losses in 1999 and 1998 reflects the acquisition of
Mid Ocean and Brockbank in 1998. In addition, the source of the Company's high
excess of loss liability and catastrophe business can result in loss payments
that are both irregular and significant. Similarly, 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".

     The Company's net incurred losses and loss expenses includes a provision of
$10.6 million, $1.2 million and $3.7 million in 1999, 1998 and 1997,
respectively, for estimates of actual and potential non-recoveries from
reinsurers. Such charges for non-recoveries relate mainly to reinsurance ceded
for casualty business written prior to 1986. Included in unpaid losses and loss
expenses at December 31, 1999, 1998 and 1997 is a reserve for potential
non-recoveries from reinsurers of $25.8 million, $14.5 million and
$13.8 million, respectively.

     Except for certain workers' compensation unpaid losses, the Company does
not discount its liabilities for unpaid losses and loss expenses. The Company
utilizes tabular reserving for workers' compensation unpaid losses that are
considered fixed and determinable and discounts such losses using an interest
rate of 7% for financial statements prepared in accordance with GAAP and a 5%
interest rate for U.S. statutory accounting purposes. The tabular reserving
methodology results in applying a uniform and consistent criteria for
establishing expected future indemnity and medical payments (including an
explicit factor for inflation) and the use of mortality tables to determine
expected payment periods. Tabular unpaid losses and loss expenses, net of
reinsurance, at December 31, 1999, 1998 and 1997 were $85.7 million,
$61.3 million and $42.4 million, respectively. The related discounted unpaid
losses and loss expenses were $28.1 million, $20.7 million and $16.1 million as
of December 31, 1999, 1998 and 1997, respectively.

</TABLE>

     Incurred but not reported ("IBNR") losses, net of reinsurance, included in
the above table was $16.1 million in 1999, $17.0 million in 1998 and
$16.6 million in 1997. Unpaid losses recoverable are net of potential
uncollectable amounts.

     As of December 31, 1999 and 1998, the Company had approximately 370 and 400
open claim files, respectively, for potential asbestos exposures and 245 and 760
open claim files, respectively, for potential environmental exposures.
Approximately 46% and 51% of the open claim files for 1999 and 1998,
respectively, are due to precautionary claim notices. Precautionary claim
notices are submitted by the ceding companies in order to preserve their right
to receive coverage under the reinsurance contract. Such notices do not contain
an incurred loss amount to the Company. The Company believes it has made
reasonable provision for its asbestos and environmental exposures and is unaware
of any specific issues that would materially affect its estimate for losses and
loss expenses. The estimation of loss and loss expense liabilities for asbestos
and environmental exposures is subject to much greater uncertainty than is
normally associated with the establishment of liabilities for certain other
exposures due to several factors, including: i) uncertain legal interpretation
and application of insurance and reinsurance coverage and liability; ii) the
lack of reliability of available historical claims data as an indicator of
future claims development; iii) an uncertain political climate which may impact,
among other areas, the nature and amount of costs for remediating waste sites;
and iv) the potential of insurers and reinsurers to reach agreements in order to
avoid further significant legal costs. Due to the potential significance of
these uncertainties, the Company believes that no meaningful range of loss and
loss expense liabilities beyond recorded reserves can be established. As these
uncertainties are resolved, additional reserve provisions, which could be
material in amount, may be necessary.

8. REINSURANCE

     The Company utilizes reinsurance and retrocession agreements principally to
increase aggregate capacity and to reduce the risk of loss on business assumed.
The Company's reinsurance and retrocession agreements provide for recovery of a
portion of loss and loss expenses from reinsurers and reinsurance recoverables
are recorded as assets. The Company is liable if the reinsurers are unable to
satisfy their obligations under the agreements.

     A 20% quota share reinsurance policy exists with several U.S. reinsurers
covering general liability insurance risks only. The maximum amount recoverable
from the reinsurers is the ceded percentage of the original policy limit on a
per occurrence basis, with an annual aggregate of 300% of the total premium
ceded.

     There are a limited amount of retrocession agreements in place for the
Company's short tail reinsurance business assumed for common account reinsurance
on proportional contracts written and "high level" property catastrophe excess
of loss protection. For the long tail casualty reinsurance business written,
several reinsurance policies are in place to limit the Company's retention on
any one claim and also for multiple claims arising from two or more risks in a
single occurrence or event.

     The Company's Lloyd's syndicates have traditionally purchased a significant
amount of reinsurance to protect against extraordinary loss or loss involving
one or more of the lines of business written. Reinsurance is purchased on an
excess of loss and quota share basis.

     The effect of reinsurance and retrocessional activity on premiums written
and earned is shown below:

     The Company recorded reinsurance recoveries on loss and loss expenses
incurred of $390.9 million, $294.0 million and $166.3 million for the years
ended December 31, 1999, 1998 and 1997, respectively. The Company is the
beneficiary of letters of credit, trust accounts and funds withheld in the
aggregate amount of $228.9 million at December 31, 1999, collateralizing
reinsurance recoverables with respect to certain retrocessionnaires.

     Increases in all of the above balances in 1999 over 1998 and in 1998 over
1997 is primarily due to the acquisition of Mid Ocean in 1998.

9. DEPOSIT LIABILITIES AND POLICY BENEFIT RESERVE

     During 1999, the Company entered into a contract that transfers
insufficient risk to be accounted for as reinsurance under SFAS No. 113. This
contract has been recorded as a deposit liability and is matched by an
equivalent amount of investments. At December 31, 1999, total deposit
liabilities are $310.4 million.

     In December 1999, the Company entered into a contract reinsuring a
portfolio of life and annuity business that has been accounted for as an
investment contract under SFAS No. 97, with a corresponding liability for
estimated future policy benefits in the amount of $635.6 million. The Company
has contracted to transfer liabilities of $108.1 million to a third party for an
equivalent consideration

10. NOTES PAYABLE AND DEBT AND FINANCING ARRANGEMENTS

     As at December 31, 1999, the Company had bank and loan facilities available
from a variety of sources including commercial banks totaling $2.16 billion
(1998: $2.24 billion) of which $410.7 million (1998: $613.9 million) was
outstanding. In addition, $891.6 million (1998: $348.9 million) of letters of
credit were outstanding, 66% of which were collateralized by the Company's
investment portfolio, primarily supporting U.S. non-admitted business,
intercompany quota share agreements between affiliates and the Company's Lloyd's
capital requirements.

     The 364-day facilities are provided by a syndicate of banks where the
borrowings are unsecured, and by a U.S. bank where the borrowings are
collateralized and guaranteed. There were no borrowings outstanding at
December 31, 1999. The weighted average interest rate on the funds borrowed
during 1999 was approximately 5.41% and approximately 5.9% during 1998.

     Two syndicates of banks provide the two five-year facilities and borrowings
are unsecured. The amounts of $299.7 million and $190.0 million outstanding at
December 31, 1999 and 1998, respectively, relate primarily to the
$300.0 million borrowed to finance the cash option election available to
shareholders in connection with the Mid Ocean acquisition in August 1998. The
1999 outstanding amount also relates to the $109.7 million borrowed to finance
the acquisition of ECS and Intercargo during 1999. The weighted average interest
rate on funds borrowed during 1999 was approximately 5.43% and 5.7% during 1998.

     In 1995, the Company issued $100.0 million of 7.15% Senior Notes due
November 15, 2005 through a public offering at a price of $99.9 million.

     $100.0 million of 5.25% Convertible Subordinated Debentures due
December 15, 2002 were issued in December 1992 through a private offering. The
Debentures were called in June 1999 and converted to approximately 1.8 million
of the Company's shares.

     $100.0 million of 8% Senior Notes due June 15, 1999 were issued in
June 1992 through a public offering. These Notes were repaid in June 1999
through additional borrowings and internal funds.

     Total pre-tax interest expense on the borrowings described above was
$37.4 million, $33.4 million and $29.6 million for the years ended December 31,
1999, 1998 and 1997, respectively. Associated with the Company's bank and loan
commitments are various loan covenants with which the Company was in compliance
throughout the three year period.

     The Company has seven letter of credit facilities available at
December 31, 1999, two from two syndicates of banks, three from U.K. banks and
two from U.S. banks. Two syndicates of banks and a U.K. bank provided the three
letter of credit facilities available at December 31, 1998. These facilities are
used to collateralize certain reinsureds' premium and unpaid loss reserves with
the Company and for Lloyd's capital requirements of the Company's corporate
syndicates. Of the letters of credit outstanding at December 31, 1999,
$591.0 million (1998: $348.9 million) were collateralized against the Company's
investment portfolio and $300.6 million (1998: Nil) were unsecured.

11. COMMITMENTS AND CONTINGENCIES

     (A) 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 foreign currency
fixed maturities and equity investments. 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 in income 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 December 31, 1999 and 1998, forward
foreign exchange contracts with notional principal amounts totaling
$339.3 million and $322.4 million, respectively, were outstanding. The fair
value of these contracts as at December 31, 1999 was $341.1 million (1998:
$316.2 million) with unrealized losses of $1.8 million (1998: $6.2 million).
Losses of $2.7 million and gains of $17.0 million were realized during 1999 and
1998, respectively.

     In addition, the Company also enters into foreign exchange contracts to buy
and sell foreign currencies in the course of trading its foreign currency
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 December 31, 1999 and 1998, the value of such contracts
outstanding was not significant.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                          (U.S. dollars in thousands)

11. COMMITMENTS AND CONTINGENCIES (CONTINUED)
     The Company attempts to hedge directly the foreign currency exposure of a
portion of its foreign currency 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
December 31, 1999, the Company had, as hedges, foreign exchange contracts for
the sale of $94.0 million and the purchase of $7.5 million of foreign currencies
at fixed rates, primarily Euros (49% of net contract value), British pounds
(18%) and New Zealand dollars (16%). The market value of fixed maturities
denominated in foreign currencies that were hedged and held by the Company as at
December 31, 1999 was $85.2 million.

     Unrealized foreign exchange gains or losses on foreign exchange contracts
hedging foreign currency fixed maturity investments are deferred and included in
shareholders' equity. As at December 31, 1999 and 1998, unrealized losses
amounted to $2.0 million and $1.3 million, respectively, and were offset by
corresponding increases 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 December 31, 1999 and 1998, realized losses amounted to $0.5 million and
$0.7 million, respectively.

     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.

     (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 December 31, 1999, the portfolio held
$121.9 million (1998: $148.2 million) in exposure to S&P 500 Index futures and
underlying assets of $122.0 million (1998: $149.6 million). The value of the
futures is updated daily with the change recorded in income as a realized gain
or loss. For the years ended December 31, 1999 and 1998, net realized gains from
index futures totaled $11.3 million and $23.2 million, respectively.

     Derivative investments are also utilized to add value to the portfolio
where market inefficiencies are believed to exist. At December 31, 1999, bond
and stock index futures outstanding were $241.1 million (1998: $235.6 million),
with underlying investments having a market value of $2.5 billion (1998:
$2.1 billion). All managers are prohibited by the Company's investment
guidelines from leveraging their positions.

     (B) 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 December 31, 1999 and 1998.

     (C) 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 $99.7 million and $33.0 million as at
December 31, 1999 and 1998, respectively, with commitments to invest a further
$131.8 million over the next ten years. The Company

received income from its investments of $9.4 million and $3.6 million for the
years ended December 31 1999 and 1998, 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.

     (D) PROPERTIES

     The Company rents space for its principal executive offices under leases
which expire up to 2009. Total rent expense for the years ended December 31,
1999, 1998 and 1997 was approximately $13 million, $9 million and $7 million,
respectively. Future minimum rental commitments under existing leases are
expected to be as follows:

     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 million, of which
$60 million has been spent to December 31, 1999. It is estimated that the
development will be completed sometime in 2001. Upon completion of the
development, it is expected that the Company's rental commitments will be
reduced.

     (E) TAX MATTERS

     The Company is a Cayman Islands corporation and, except as described below,
neither it nor its non-U.S. subsidiaries have 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, regulations or court decisions, there can be no assurance
that the Internal Revenue Service 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 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.

11. COMMITMENTS AND CONTINGENCIES (CONTINUED)
     (F) FINANCIAL GUARANTIES

     The Company insures and reinsures financial guaranties issued to support
public and private borrowing arrangements. Financial guaranties are conditional
commitments which guaranty the performance of a customer to a third party. The
Company's potential liabilities in the event of nonperformance by the issuer of
the insured obligation is represented by its proportionate share of the
aggregate outstanding principal and interest payable ("insurance in force") on
such insured obligation. At December 31, 1999, the Company's aggregate insurance
in force was $5.2 billion. The Company manages its exposure to credit risk
through a structured underwriting process which includes detailed credit
analysis, review of and adherence to underwriting guidelines, surveillance
policies and procedures and the use of reinsurance.

12. SHARE CAPITAL

     (A) AUTHORIZED AND ISSUED

     The authorized share capital is 999,990,000 ordinary shares of a par value
of $0.01 each. Holders of Class A shares are entitled to one vote for each share
held while Class B shares are not entitled to vote. In all other respects,
Class A and B shares rank PARI PASSU.

     The Company has had several stock repurchase plans in the past as part of
its capital management. In June 1999, the Board of Directors rescinded the
Company's share repurchase plans. On January 9, 2000 the Board of Directors
authorized the repurchase of shares up to $500 million.

     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 the 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.

12. SHARE CAPITAL (CONTINUED)

     Restricted stock awards issued under the 1991 Performance Incentive Program
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 113,100
shares, 147,836 shares and 91,000 shares in 1999, 1998 and 1997, respectively.
Restricted stock awards granted by NAC prior to the merger amounted to 3,627
shares, 23,700 shares and 65,300 shares for the same respective periods. Vesting
for such shares generally occurs over a six year period.

     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 the grant date. Effective
April 11, 1997, all options granted to non-employee directors are granted under
the 1991 Performance Incentive Program. 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 shares
calculated by dividing 110% of the deferred payment by the market value of the
Company's stock at the beginning of the fiscal year. Each anniversary
thereafter, 20% of these shares are distributed. Shares issued under the plan
totaled nil, 2,737 and 3,048 in 1999, 1998 and 1997, 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. Stock units totaling 1,217,
5,531 and 6,716 were provided for in 1999, 1998 and 1997, respectively.

     As a result of the merger with Mid Ocean during August 1998, 791,573 Mid
Ocean options were converted to options of XL Capital. These are 10 year options
that generally vest over 3 years.

     Following the merger with NAC, new option plans were created in the Company
to adopt the NAC plans. Options generally have a five or six year vesting
schedule, with the majority expiring 10 years from the date of grant; the
remainder having no expiration. A stock plan is also maintained for non-employee
directors. Options expire 10 years from the date of grant and are fully
exercisable six months after their grant date.

     In 1999, the Company adopted the 1999 Performance Incentive Plan under
which 1,250,000 options were available and issued to employees who were not
directors or executive officers of the Company.

     (D) FAS 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 awards

     (F) VOTING

     XL's Articles of Association restrict the voting power of any person to
less than 10% of total voting power.

     (G) SHARE RIGHTS PLAN

     Rights to purchase Ordinary Shares were distributed as a dividend at the
rate of one Right for each outstanding Ordinary Share held of record as of the
close of business on October 31, 1998. Each Right entitles holders of XL
Ordinary Shares to buy one ordinary share at an exercise price of $350. The
Rights would be exercisable, and would detach from the Ordinary Shares, only if
a person or group were to acquire 20% or more of XL's outstanding Ordinary
Shares, or were to announce a tender or exchange offer that, if consummated,
would result in a person or group beneficially owning 20% or more of XL's
Ordinary Shares. Upon a person or group without prior approval of the Board
acquiring 20% or more of XL's Ordinary Shares, each Right would entitle the
holder (other than such an acquiring person or group) to purchase XL Ordinary
Shares (or, in certain circumstances, 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. The Company has initially reserved 119,073,878 Ordinary Shares being
authorized and unissued for issuance upon exercise of the Rights.

13. RETIREMENT PLANS

     The Company maintains both defined contribution and defined benefit
retirement plans, which vary for each subsidiary. Plan assets are invested
principally in equity securities and fixed maturities.

     The Company has a qualified defined contribution plan which is managed
externally and whereby employees and the Company contribute a certain percentage
of the employee's gross salary into the plan each month. The Company's
contribution generally vests over 5 years.

13. RETIREMENT PLANS (CONTINUED)
     At NAC, a qualified non-contributory defined benefit pension plan exists to
cover substantially all its U.S. employees. Benefits are based on years of
service and compensation, as defined in the plan, during the highest consecutive
three years of the employee's last ten years of employment.

     Under this plan, the Company's policy is to make annual contributions to
the plan that are deductible for federal income tax purposes and that meet the
minimum funding standards required by law. The contribution level is determined
by utilizing the entry age cost method and different actuarial assumptions than
those used for pension expense purposes. This plan also includes a non-qualified
supplemental defined benefit plan designed to compensate individuals to the
extent their benefits under the Company's qualified plan are curtailed due to
Internal Revenue Code limitations. The projected benefit obligation, accumulated
benefit obligation and fair value of the assets for this plan with accumulated
benefit obligations in excess of the plan assets were $4.6 million,
$2.5 million and Nil, respectively, as of December 31, 1999 and $5.0 million,
$2.5 million and Nil, respectively as of December 31, 1998. The discount rates
used in determining the actuarial present value of benefit obligations were 7.7%
and 6.5% for 1999 and 1998, respectively. The rate of increase for future
compensation levels was 6.5% for 1999 and 5.5% for 1998. The assumed rate of
return on plan assets was 9.0% for both 1999 and 1998.

     NAC also maintains a qualified contributory defined contribution plan for
substantially all its U.S. employees and a qualified non-contributory defined
contribution plan for all its U.K. employees.

     The Company's expenses for its retirement plans is not considered to be
significant.

15. CONTRIBUTED SURPLUS

     Under the laws of the Cayman Islands, the use of the Company's contributed
surplus is restricted to the issue of fully paid shares (i.e. stock dividend or
stock split) and the payment of any premium on the redemption of ordinary
shares.

16. DIVIDENDS

     The following dividend information relates to the Company without inclusion
of the pooling effect with NAC:

     In 1999, four regular quarterly dividends were paid at $0.44 per share to
shareholders of record at February 5, April 23, July 12 and September 24.

     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
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.

17. TAXATION

     Under current Cayman Islands law, the Company is not subject to any taxes
in the Cayman Islands on either income or capital gains. The Company has
received an undertaking that, in the event of any such taxes being imposed, the
Company will be exempted from Cayman Islands income or capital gains taxes until
June 2018.

     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
provision for federal income taxes has been determined on the basis of the
income of each of the Company's U.S. subsidiaries as if a tax return had been
prepared on an individual Company basis. Should the U.S. subsidiaries pay a
dividend to the Company, withholding taxes will apply.

     Bermuda presently imposes no income, withholding or capital gains taxes and
the 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.

     XL Europe has been approved to carry on business in the International
Services Centre in Dublin. Under Section 39 of the Finance Act 1990, XL Europe
is entitled to benefit from a 10% tax rate on profits (including investment
income) until 2005.

     Brockbank, NAC Re International and XL Mid Ocean Re's London branch office
are subject to United Kingdom corporation taxes. Other branches of the Company
are subject to relevant local taxes.

     The income tax provision in the consolidated statement of income gives
effect to the permanent differences between financial and taxable income as
applied for each relevant subsidiary. Due to the fact that the Company and
certain subsidiaries are not subject to direct U.S. income taxes and that
certain U.S. subsidiaries have tax-exempt income, the Company's effective income
tax rate for its U.S. operation is less than the statutory U.S. Federal tax
rate.

     The tax charge (benefit) in each of the three years ended December 31, 1999
is comprised of amounts from the various taxable jurisdictions in which the
Company operates. For all countries other than the U.S., there generally is no
significant difference between the effective tax rate and the statutory rate in
that jurisdiction. For U.S. operating income (loss), the effective rate differs
from the statutory rate of 35% due primarily to tax-exempt investment income in
all years and merger related costs in 1999.

     Significant components of the provision for income taxes attributable to
operations were as follows:

17. TAXATION (CONTINUED)
     The U.S. subsidiaries current U.S. taxable income for the years ended
December 31, 1999 and 1997 is based on regular taxable income. The current U.S.
tax expense for the year ended December 31, 1998 is based on alternative minimum
taxable income.

     U.S. and Non-U.S. taxes paid in the years ended December 31, 1999, 1998 and
1997 were approximately $30 million, $31 million and $38 million, respectively.
The Company's current tax liability is included in "other liabilities" in the
accompanying financial statements and amounted to $11 million in 1999 and
$26 million in 1998.

     Significant components of the Company's deferred tax assets and

     The primary difference between statutory net income and statutory capital
and surplus for the Company's subsidiaries, as shown above, and net income and
shareholders' equity presented in accordance with GAAP are deferred acquisition
costs.

     Under the Act, XL Insurance and XL Mid Ocean Re 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 statutory requirements.
XL Insurance and XL Mid Ocean Re have not been affected by this.

     UNITED STATES

     The Company's U.S. insurance and reinsurance subsidiaries are subject to
regulatory oversight under the insurance statutes and regulations of the
jurisdictions in which they conduct business.

     Consolidated statutory net income and surplus of NAC Re, as reported to the
insurance regulatory authorities, differs in certain respects from the amounts
as prepared in accordance with GAAP. The main differences between statutory net
income and GAAP income relates to deferred acquisition costs and deferred income
taxes. The main differences between statutory surplus and shareholders' equity,
in addition to deferred acquisition costs and deferred income tax net assets,
are intangible assets, unrealized appreciation on investments, and any
unauthorized/authorized reinsurance charges.

     NAC Re is subject to New York insurance law, which imposes certain
restrictions on the payment of cash dividends and tax reimbursements. Generally,
NAC Re may pay cash dividends only out of statutory earned surplus. However, the
maximum amount of dividends that may be paid in any twelve month period without
the prior approval of the New York Insurance Department is the lesser of net
investment income or 10% of statutory surplus as such terms are defined in the
New York insurance law. Statutory earned surplus at December 31, 1999 is $(27.7)
million and consequently, NAC Re cannot make a dividend distribution. In
addition, the Company was required to make a commitment to New York State
insurance regulators not to pay dividends out of NAC Re for two years without
prior regulatory approval. Statutory earned surplus at December 31, 1998 was
$231.9 million and the maximum amount NAC Re was able to pay without such
regulatory approval, based on 10% of statutory surplus as of December 31, 1998
was approximately $73.7 million.

     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, Kansas and Arizona. Brockbank
Insurance Services, Inc., is licensed in California as a fire and casualty
broker, surplus lines broker and special lines surplus lines broker.

     The insurance laws of each state of the U.S. and of many foreign countries
regulate the sale of insurance within their jurisdiction by alien insurers, such
as XL Insurance and XL Mid Ocean Re. 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, amongst 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 assurances, 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.

     IRELAND

     XL Europe is permitted to cover risks throughout the European Community
(subject to certain restrictions) pursuant to the "Third Directive" relating to
non-life insurance. Its head office is in Ireland and it is subject to
regulation under Irish regulatory authority. The principal legislation and
regulations governing the insurance activities of Irish insurance companies are
the Insurance Acts 1909 to 1990 (the "Irish Acts") and 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)
Regulations, 1976, the European Communities (Non-Life Insurance Accounts)
Regulations, 1995, the European Communities (Non-Life Insurance) Framework
Regulations, 1994 and related administrative rules (the "Irish Regulations".)

     XL Europe's insurance activities are subject to extensive regulation in
Ireland, principally under the Irish Acts and Irish Regulations, which impose on
insurers headquartered in Ireland minimum solvency and reserve standards and
auditing and reporting requirements and grant to the Minister of State for
Science, Technology and Commerce (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 medium of the Department of
Enterprise, Trade and Employment.

     UNITED KINGDOM

     The United Kingdom Financial Services Authority ("U.K. FSA") regulates
reinsurance entities that are "effecting and carrying on" insurance business in
the United Kingdom. Both XL Mid Ocean Re, through its London branch and NAC Re,
through its London subsidiary, "effect and carry on" business in the United
Kingdom and are therefore regulated by the U.K. FSA.

     LLOYD'S

     The Company, Brockbank and Denham are subject to the regulatory
jurisdiction of the Council of Lloyd's (the "Council"). Unlike other financial
markets in the U.K., Lloyd's is not subject to direct U.K. government regulation
through The Financial Services Act of 1986 but, instead, is self regulating by
virtue of the Lloyd's Act of 1982 through the bye-laws, regulations and codes of
conduct written by the Council, which governs the market. It is expected that
the new Financial Services Authority will take a supervisory regulatory role
during 2000. Under the Council, there are two boards, the Market Board and the
Regulatory Board. The former is led by a number of the 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 managing agency. The Company has been
approved as both a "major shareholder" and a "controller" of its corporate Names
(the "CCVs") and managing agencies.

     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.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Shareholders of XL Capital Ltd.:

     In our opinion, based upon our audits and the report of other auditors, the
accompanying consolidated balance sheets, the related consolidated statements of
income and comprehensive income, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of XL
Capital Ltd. and its subsidiaries at December 31, 1999 and 1998, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1999, in conformity with accounting principles
generally accepted in the United States of America. In addition, in our opinion,
the financial statement schedules listed in Item 14(a) of this Form 10-K, when
considered in relation to the basic financial statements taken as a whole,
present fairly, in all material respects, the information required to be
included therein. These financial statements and financial statement schedules
are the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements and financial statement
schedules based on our audits. We conducted our audits of these statements and
schedules in accordance with generally accepted auditing standards 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. We did not
audit the financial statements or financial statement schedules of NAC Re Corp.
as at December 31, 1998, which statements reflect total assets of $3.2 billion
as of December 31, 1998 and total revenues of $699.4 million and $740.4 million
for the years ended December 31, 1998 and 1997, respectively. Those statements
were audited by other auditors whose report thereon has been furnished to us,
and our opinion expressed herein, insofar as it relates to the amounts included
for NAC Re Corp. for those dates, is based solely on the report of the other
auditors.

     We previously audited and reported on the consolidated balance sheets, the
related consolidated statements of income and comprehensive income, of
shareholders' equity and of cash flows and the supplemental schedules of XL
Capital Ltd. and its subsidiaries as at and for the two years ended
November 30, 1998 prior to their restatement for the 1999 pooling of interests
and change in fiscal year. We also audited the combination of the accompanying
consolidated balance sheet as of December 31, 1998 and the consolidated
statements of income and comprehensive income, of shareholders' equity and of
cash flows for the two years ended December 31, 1998, after restatement for the
1999 pooling of interest. In our opinion, such consolidated statements have been
properly combined on the basis described in Note 6 of the consolidated financial
statements.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
NAC Re Corporation:

     We have audited the consolidated balance sheet of NAC Re Corporation and
subsidiaries as of December 31, 1998 and the related consolidated statements of
income, stockholders' equity and cash flows for each of the two years in the
period ended December 31, 1998 (not presented separately herein). Our audits
also included the financial statements schedules listed in the Index at Item 14
of the 1998 NAC Re Corporation annual report on Form 10-K (not presented
separately herein). These financial statements and schedules are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and schedules based on our audits.

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

                              CONSULTING AGREEMENT


      This CONSULTING AGREEMENT ("Agreement"), made and entered into as of July
1, 1999, by and between NAC RE CORPORATION, a Delaware corporation (the
"Company"), and RONALD L. BORNHUETTER ("Bornhuetter").

      WHEREAS, Bornhuetter has terminated his employment with the Company
effective as of the date hereof; and

      WHEREAS, the Company wishes to continue to avail itself of the services of
Bornhuetter as a Consultant to the Company, and Bornhuetter is willing to
continue to perform services in that capacity on behalf of the Company;

      NOW, THEREFORE, in consideration of the premises and mutual covenants
contained herein and for other good and valuable consideration, the Company and
Bornhuetter (each individually, a "Party," and collectively, the "Parties")
agree as follows:

      1. GENERAL.

      The Company engages Bornhuetter as a consultant for the period as set
forth in Section 2 to provide the services as set forth in Section 3, subject to
the other terms and conditions set forth in this Agreement.

      2. TERM OF SERVICE.

      The term of Bornhuetter's service under this Agreement shall commence as
of July 1, 1999 (the "Effective Date") and shall terminate on the second
anniversary of the Effective Date unless there is an earlier termination of
Bornhuetter's service pursuant to Section 7 (the "Term of Service").

      3. SERVICES.

      During the Term of Service, it is the intention of the Parties that
Bornhuetter serve as a consultant to the Company. As a consultant, Bornhuetter
shall perform such consulting duties and render such advice, including, but not
by way of limitation, duties and advice relating to integration of the Company
with XL Capital Ltd. ("XL") following the Company's merger with a subsidiary of
XL and international reinsurance matters, as the Chief Executive Officer (the
"CEO") of XL may reasonably specify. The CEO may request Bornhuetter to render
such services for up to 20 days per calendar quarter, subject to Bornhuetter's
reasonable convenience and his other business commitments. Bornhuetter shall
serve as a member of the Board of Directors of XL, if appointed thereto, and of
such other boards as may be


<PAGE>

mutually agreed upon by the Parties. Bornhuetter's services shall be rendered in
New York, Connecticut and such other locations as may be mutually agreed upon by
the Parties.

      4. FEES.

      During the Term of Service, Bornhuetter shall receive a base annual fee of
$250,000 (the "Base Annual Fee") payable in 12 monthly installments of
$20,833.33 each at the end of each month, together with any applicable
directors' fees.

      5. BUSINESS EXPENSES.

      (a) DOCUMENTED EXPENSES. Bornhuetter shall be entitled to receive prompt
and full reimbursement for all reasonable business expenses (other than office
and secretarial expenses) incurred by him in rendering services to the Company
under this Agreement, provided that Bornhuetter shall provide documentation of
such expenses in accordance with the usual practices of the Company. Such
reimbursement shall include up to $10,000 per year for expenses related to
Bornhuetter's actuarial society activities.

      (b) OFFICE ALLOWANCE. In addition, the Company shall pay Bornhuetter an
allowance of $10,000 per year for office and secretarial expenses.

      6. INDEPENDENT CONTRACTOR STATUS.

      As a Consultant, Bornhuetter's status shall be that of independent
contractor. Bornhuetter acknowledges that the Company will not withhold any
federal, state or local taxes from the fees to be paid hereunder.

      7. TERMINATION OF SERVICE.

      (a) TERMINATION BY THE COMPANY OTHER THAN DUE TO DEATH, DISABILITY OR FOR
CAUSE. In the event the Company terminates Bornhuetter's service for any reason
other than death, as provided in Section 7(b), Disability, as provided in
Section 7(c), or Cause, as provided in Section 7(d), the Company shall pay to
Bornhuetter the monthly sum of $20,833.33 until June 30, 2001.

      (b) TERMINATION DUE TO DEATH. In the event Bornhuetter's service is
terminated due to his death, the Company shall pay to his designated beneficiary
or other legal representative the monthly installment of the Base Annual Fee for
the month in which Bornhuetter's death occurs, as well as any unreimbursed
business expenses. The Company shall have no further obligation to pay advisory
fees under this Agreement.

      (c) TERMINATION DUE TO DISABILITY. In the event Bornhuetter's service is
terminated due to his Disability, the Company shall pay Bornhuetter the monthly
installment

<PAGE>

of the Base Annual Fee for the month in which termination occurs, as well as any
unreimbursed business expenses. The Company shall have no further obligation to
pay advisory fees under this Agreement. For this purpose, "Disability" shall
mean any physical or mental disability which renders Bornhuetter incapable of
carrying out his duties or responsibilities under this Agreement, provided that
Bornhuetter shall not be considered to have suffered such disability unless he
shall have been unable to carry out such duties or responsibilities for a period
of at least 180 consecutive days. A determination of Disability will be subject
to the certification of a qualified medical doctor appointed by the Company and
reasonably acceptable to Bornhuetter.

      (d) TERMINATION VOLUNTARILY OR FOR CAUSE. In the event Bornhuetter
terminates his service under this Agreement voluntarily or Bornhuetter's service
is terminated by the Company for Cause, the Company shall pay Bornhuetter the
monthly installment of the Base Annual Fee for the month in which termination
occurs, prorated to the date of termination, as well as any unreimbursed
business expenses and the office expense allowance described in Section 5(b),
pro rated to the date of termination. The Company shall have no further
obligation to pay advisory fees under this Agreement. Termination for Cause
shall mean a termination of Bornhuetter's service following his commission of a
felony, a termination because Bornhuetter, in carrying out his duties hereunder,
has engaged in willful gross misconduct resulting in material harm to the
Company, or a termination because Bornhuetter has breached Section 8 or Section
9 of this Agreement. A voluntary termination shall be deemed to include (i) the
failure or refusal by Bornhuetter to accept an appointment to the Board of
Directors of XL or any affiliate of XL or the Company and (ii) Bornhuetter's
resignation from the Board of Directors of XL or from the Board of Directors of
the Company or any affiliate of XL or the Company without the consent of the
Board of Directors of XL.

      8. NON-COMPETITION AND NON-SOLICITATION.

      (a) NON-COMPETE. Bornhuetter shall not engage in competition with the
Company so long as he is serving as a director of XL, the Company or any
affiliate of XL or the Company. Bornhuetter may resign as director at any time,
in which case the provisions of Section 7(d) shall apply. Exception will be made
for his providing actuarial services and for any opportunities for which he
received written consent from the Company. "Competition" shall mean engaging in
any activity for a Competitor, whether as an employee, consultant, officer or
director, or shareholder (except as a less than one percent shareholder of a
publicly traded company) or otherwise. A "Competitor" shall mean any corporation
or other entity which competes with the Company's business, as determined on the
Effective Date. Bornhuetter's actuarial activities shall not be considered a
violation of this Section 8.

      (b) NON-SOLICIT. During the Term of Service, Bornhuetter shall not induce
any employees of the Company, XL or any of their affiliates to terminate their
employment,


<PAGE>

nor shall Bornhuetter solicit or encourage any customers or any corporation or
other entity in a joint venture relationship with the Company, XL or any of
their affiliates, to terminate their or its relationship with the Company, XL or
any of their affiliates or to violate any agreement with any of them.

      (c) TERMINATION OF NON-COMPETE/NON-SOLICIT. The provisions of Sections
8(a) and 8(b) shall terminate upon the earlier to occur of (i) 24 months from
the Effective Date or (ii) Bornhuetter's resignation from the Board of Directors
of XL, the Company, or any affiliate of XL or the Company.

      9. CONFIDENTIAL INFORMATION AND TRADE SECRETS.

      Bornhuetter hereby acknowledges that he has had and in the future may have
access to and become acquainted with various trade secrets and proprietary
information of the Company, XL and their affiliates not available to competitors
of the Company, XL and their affiliates including, without limitation,
information relating to their products, product development, trade secrets,
customers, suppliers, finances, management, operations and business plans and
strategies. Bornhuetter covenants that he will not, directly or indirectly,
disclose or use such information except as is necessary and appropriate in
connection with the rendering by him of services to the Company under this
Agreement or except as may be required by a court of law, a governmental agency
having supervisory authority over the business of the Company or by any
administrative or legislative body (including a committee thereof) with
jurisdiction to order him to divulge, disclose or make accessible such
information; provided, however, that Bornhuetter agrees that, before making such

reasonable fees and disbursements for independent counsel for Bornhuetter, if
Bornhuetter reasonably determines, based on an opinion of counsel furnished to

court in connection with any breach or proposed breach by the Executive of the
provisions of Sections 8 and 9. For the purpose of any such equitable relief,
the Executive hereby submits to the exclusive jurisdiction of the courts of the
state of New York and the federal courts of the United States of America located
in such state and hereby waives, and agrees not to assert, as a defense in any
action, suit or proceeding for such equitable relief, that he is not subject

proceeding shall be deemed in every respect effective service of process upon
him if given in the manner set forth in Section 13 or if effected by any legally

                              SETTLEMENT AGREEMENT


      THIS SETTLEMENT AGREEMENT (the "Agreement") is made and entered into as of
June 30, 1999, by and between RONALD L. BORNHUETTER ("Executive"), NAC RE
CORPORATION, a Delaware corporation, and NAC REINSURANCE CORPORATION, a New York
corporation (together, the "Company").

                              STATEMENT OF PURPOSE

      Executive has been employed by the Company under the terms of that certain
Employment Agreement between Executive and the Company dated October 30, 1996
(the "Employment Agreement"). The Employment Agreement provides that Executive
will be entitled to receive certain payments and benefits if his employment is
terminated.

      Executive's employment with the Company ceased effective as of June 30,
1999. The Company and Executive wish to confirm in this Agreement that Executive
has terminated his employment for Good Reason pursuant to Section 8(c) of the
Employment Agreement and to specify the termination payments and other benefits
that will be provided to Executive under the Employment Agreement and certain
other documents, contracts and plans, as well as certain other consideration,
and to settle in full all matters and claims, contractual and non-contractual,
relating to Executive's employment with the Company.

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements contained herein, the parties hereto agree as follows:

      1. RESIGNATION; RETIREMENT.

      Executive hereby resigns from his position as Chief Executive Officer of
the Company and resigns his membership on the Board of Directors of the Company
and his position as Chairman thereof, effective June 18, 1999. Executive agrees
that he will resign from any and all offices and directorships of any and all
affiliates of the Company promptly following the request of such Board of
Directors. Effective as of June 30, 1999 (the "Termination Date"), Executive
shall cease to be an employee of the Company or any affiliate. For the purposes
of all Company benefit plans and programs, including, without limitation, the
Supplemental Pension pursuant to Section 5 of the Employment Agreement, such
termination of employment shall be treated as a retirement.

      2. TERMINATION PAYMENTS AND BENEFITS.

      Executive shall receive the following payments and benefits as a result of
his termination of employment:

<PAGE>
                                      -2-


      (a) LUMP SUM CASH SEVERANCE. On or before July 15, 1999, the Company shall
pay to Executive a lump sum cash severance payment and accrued bonus obligations
in the aggregate amount of $4,659,812, representing the following:

       Amount pursuant to Section 8(b)(i)(B)                       $3,946,785
       of the Employment Agreement

       Annual Incentive Plan                                         $144,394

       Long-term Incentive Plan                                      $568,633

      (b) STOCK OPTIONS. All of Executive's currently outstanding stock options,
listed on Exhibit A hereto, are fully vested and exercisable, have been
converted into options to purchase the number of shares of common stock of XL
Capital Ltd. ("XL") reflected in Exhibit A, and shall remain exercisable until
the expiration of the exercise period provided in the applicable option
agreement (but in no event beyond its maximum stated term), as provided in
Exhibit A.

      (c) SUPPLEMENTAL PENSION. In accordance with Section 5 of the Employment
Agreement, the Company shall pay to Executive $162,892 per year in equal monthly
installments commencing August 1, 1999. Such benefit shall be paid to Executive
for his lifetime and, following his death, 50% of such amount shall continue to
be paid to his surviving spouse for her lifetime commencing on the first day of
the month immediately after the date of Executive's death. Funding of the
benefit under this Section 2(c) shall be provided through a "Rabbi Trust"
established by the Company. The Company will maintain the assets of the trust at
a level at least equal to the lump sum value of future payments, determined
using the following accepted actuarial principles and assumptions: for
mortality, the UP 1984 Mortality Table, and for interest, the applicable
interest rate, as then in effect, used by the Pension Benefit Guaranty
Corporation to value immediate annuities in connection with the termination of a
single-employer plan under the Employee Retirement Income Security Act of 1974,
as amended. To the extent the assets held in the trust exceed the foregoing lump
sum value, the excess amount shall be returned to the Company or shall remain in
the trust for the contingency of future increases in the lump sum value, as
elected by the Company.

      (d) CONTINUATION OF MEDICAL, VISION AND DENTAL BENEFITS. The Company shall
provide Executive and his spouse with medical, vision and dental benefits on the
same basis as such benefits were provided prior to the Termination Date, by
purchasing and maintaining equivalent medical, vision and dental coverage on
Executive's behalf, for a period of 36 months commencing July 1, 1999. After
July 2002, the Company shall use its best efforts to continue the eligibility of
Executive and his spouse in its group insurance benefits; provided, however,
that the costs of such benefits shall be borne by Executive.

<PAGE>
                                      -3-


      (e) CONTINUATION OF LIFE INSURANCE BENEFIT. Commencing July 1, 1999 and
continuing until June 30, 2002, the Company shall maintain for the benefit of
Executive life insurance coverage with an aggregate death value of $750,000.
Commencing July 1, 2002, the Company shall purchase and maintain at its expense
for the remainder of Executive's life, and for Executive's benefit, life
insurance coverage having an aggregate death value of $100,000. Executive shall
be the owner of and shall have the right to designate or change the beneficiary
or beneficiaries of the insurance described in this Section 2(e), and such
insurance shall be provided in a form whereby Executive may create an
irrevocable trust as the owner of such insurance.

      (f) OTHER BENEFITS. Executive is a participant in the benefit plans listed
in Exhibit B hereto. This Agreement shall not change the terms of such plans or
the benefits earned by or due to Executive thereunder for services rendered to
the Company through the Termination Date. The benefits earned by or due to
Executive in accordance with the terms of such plans shall be paid or provided
by the Company or such plans (as the case may be) when due (whether such due
date is on, before or after the Termination Date), and full payments and
provision of benefits shall discharge fully all obligations of the Company and
such plans with respect to Executive's benefits under such plans. In addition,
the Company shall pay to Executive a lump sum amount equal to $48,293.21 (the
value of 19.5 vacation days based on six months of employment in 1999), payable
in accordance with the Company's general practices for reimbursement for unpaid
vacation days.

      3. TAX WITHHOLDING AND REPORTING.

      The Company shall be entitled to withhold from the benefits and payments
described herein all income and employment taxes required to be withheld by
applicable law.

      4. RELEASE OF THE COMPANY.

      Executive, on behalf of himself and his heirs, personal representatives,
successors and assigns, hereby releases and forever discharges the Company, its
affiliates, and each and every one of their respective present and former
directors, officers, employees, agents, successors and assigns from and against
any and all claims, demands, damages, actions, causes of action, costs and
expenses, which Executive now has, may ever have had or may have hereafter upon
or by reason of any matter, cause or thing occurring, done or omitted to be done
prior to the date of this Agreement, that constitute "Employment-Related Claims"
or rights and claims Executive has or might have under the Worker Adjustment and
Retraining Notification Act, the Age Discrimination in Employment Act of 1967,
as amended ("ADEA"), Title VII of the Civil Rights Act of 1964, as amended, and
the Americans with Disabilities Act of 1990, as amended; PROVIDED, HOWEVER, that
this release shall not apply to any claims which Executive may have for the

or referenced in this Agreement, including the Exhibits hereto, and that

<PAGE>
                                      -4-


this release shall not apply to any rights Executive may have to obtain
contribution in the event of the entry of judgment against him as a result of
any act or failure to act for which both Executive and the Company are jointly
responsible. For purposes of this Agreement, "Employment -- Related Claims"
means all rights and claims Executive has or may have related to his employment
by or status as an employee, officer or director of the Company or any of its
affiliates or to the termination of that employment or status or to any
employment practices and policies of the Company or its affiliates.

      Executive acknowledges and agrees that he has read this release in its
entirety and that this release is a general release of all known and unknown
claims, including rights and claims arising under ADEA. Executive and the
Company further acknowledge and agree that:

      (i)   This release does not release, waive or discharge any rights or
            claims that may arise for actions or omissions which occur after the
            date of this Agreement;

      (ii)  Executive is entering into this Agreement and releasing, waiving and
            discharging rights or claims only in exchange for consideration
            which he is not already entitled to receive;

      (iii) Executive has been advised, and is being advised by this release, to
            consult with an attorney before executing this Agreement;

      (iv)  Executive has been advised, and is being advised by this release,
            that he has up to twenty-one (21) days within which to consider this
            release; and

      (v)   Executive is aware that this release will not become effective or
            enforceable until seven (7) days following his execution of this
            Agreement and that he may revoke this release at any time during
            such period by delivering (or causing to be delivered) to the
            Company at the address provided in Section 11 hereof written notice
            of his revocation of this release no later than 5:00 p.m. eastern
            time on the seventh (7th) full date following his execution of this
            Agreement.

      5. RELEASE OF EXECUTIVE.

      In consideration of Executive's entering into this Agreement, the Company,
for itself, its officers and directors, its affiliates and their respective
predecessors, successors and assigns hereby releases and forever discharges
Executive and his heirs, personal representatives, successors and assigns from
and against any and all claims, demands, damages, actions, causes of action,
costs and expenses, of whatever kind or nature, in law, equity or otherwise,

<PAGE>
                                      -5-


which the Company or any of said entities now has, may ever have had or may have
hereafter upon or by reason of any matter, cause or thing occurring, done or
omitted to be done prior to the date of this Agreement, including without
limitation all rights and claims the Company or any of said entities or any
third parties (including officers, directors and employees of the Company or its
affiliates) have or might have as a result of Executive's status as an officer,
director or employee of the Company or any of said entities or the termination
of that status; PROVIDED, HOWEVER, that this release shall not apply to any
claims the Company may have which arise out of or relate to the conviction of
Executive for the commission of a crime involving dishonesty with respect to the
Company, its affiliates or their respective predecessors. As of the date of this
Agreement, the Company has no knowledge of any potential claim against Executive
arising out of any of the events described above.

      6. INDEMNIFICATION.

      The Company and/or its affiliates shall indemnify and hold harmless
Executive, his heirs and his personal representatives to the fullest extent
permitted by applicable law, as now or hereafter in effect, with respect to any
acts, omissions or events that occurred while Executive was an employee of the
Company or any affiliate or served the Company, any affiliate or any other
corporation or enterprise of any kind in any capacity at the request of the
Company or any affiliate (an "Enterprise"). Without limiting the generality of
the foregoing, such indemnification shall include the prompt payment or
reimbursement to Executive for (a) all of Executive's reasonable expenses,
including attorneys' fees and court costs, actually and reasonably incurred in
connection with the defense of any action, suit or proceeding or in connection
with any appeal thereof, to which Executive may be a party by reason of any
action taken or failure to act under or in connection with his service for the
Company, any affiliate or an Enterprise, and (b) all amounts required to be paid
in settlement or in satisfaction of a judgment in connection with any such
action, suit or proceeding; provided, however, that the Company and any
affiliate shall not be required to indemnify or hold harmless Executive, his
heirs or personal representatives in any matter whatsoever in the event and to
the extent that there is a final and nonappealable judgment by a court of
competent jurisdiction that the liability incurred by Executive resulted from
his gross negligence, fraud or willful malfeasance.

      7. GROSS-UP PAYMENT.

      In the event that any payments or benefits (the "Severance Payments")
provided for in this Agreement (including, but not limited to, the rights
provided under Section 2(b)) are subject to the tax (the "Excise Tax") imposed
by Section 4999 of the Internal Revenue Code of 1986, as amended, or any
successor provision, the Company shall pay to the Executive an additional amount
(the "Gross-Up Payment") such that the net amount retained by the Executive,
after deduction of any Excise Tax on the Severance Payments and any federal,
state and local income taxes and Excise Tax (including interest and penalties)
upon the pay-

<PAGE>
                                      -6-


ment provided for in this Section 7, shall be equal to the Severance Payments.
The determination whether any payments made pursuant to this Agreement are
subject to the Excise Tax shall be based on the opinion of tax counsel selected
by the Executive and reasonably acceptable to the Company. For purposes of
determining the amount of the Gross-Up Payment, the Executive shall be deemed to
pay federal, state and local income taxes at the highest marginal rate of income
taxation applicable to any individual residing in the jurisdiction in which the
Executive resides in the calendar year in which the Gross-Up Payment is to be
made. In the event that the Excise Tax is subsequently determined to be less
than the amount initially determined hereunder, the Executive shall promptly
repay to the Company the portion of the Gross-Up Payment attributable to such
reduction. In the event that the Excise Tax is subsequently determined to exceed
the amount initially determined hereunder, the Company shall promptly make an
additional Gross-Up Payment in respect of such excess.

      8. CONFIDENTIALITY.

      (a) For the period during which this Agreement has not been publicly
disclosed by the Company, Executive hereby covenants and agrees to keep in full
confidence all information concerning this Agreement except (i) to the extent

court of law, by any governmental agency having supervisory authority over the
business of the Company or by any administrative or legislative body (including
a committee thereof) with apparent jurisdiction to order him to divulge,
disclose or make accessible such information, (ii) to the extent disclosure to
Executive's legal counsel and personal financial advisors is reasonably
necessary in connection with Executive's consideration of the terms of this
Agreement or Executive's personal financial dealings, or (iii) to members of his
immediate family.

      (b) The Company hereby covenants and agrees to keep in full confidence all
information concerning this Agreement except (i) to the extent disclosure is or

make accessible such information, (ii) to the extent disclosure to the Company's
legal counsel and auditors is reasonably necessary or (iii) to those persons
within the Company, who as reasonably determined by the Company, must know about
it in carrying out their duties.

      (c) Executive and the Company acknowledge and agree that each shall be
entitled to enforce specifically the covenants in this Section 8 by seeking an
injunction to prevent violation thereof in addition to any other remedies
available at law or in equity.

                              EMPLOYMENT AGREEMENT



      AMENDED AND RESTATED EMPLOYMENT AGREEMENT, made as of June 18, 1999, by
and among XL Capital Ltd ("AXL"), Dasher Acquisition Corp. ("ACQUISITION"), NAC
Re Corporation ("NAC RE") and NAC Reinsurance Corporation ("NAC") (collectively,
NAC Re and NAC shall be referred to as the "COMPANY" or the "EMPLOYER"), and
Nicholas M. Brown, Jr. ("EXECUTIVE").

                               W I T N E S S E T H


      WHEREAS, as of June 10, 1998, the Company and the Executive entered into
an employment agreement (the "AGREEMENT"); and

      WHEREAS, XL, Acquisition and the Company have entered into an Agreement
and Plan of Merger (the "MERGER AGREEMENT"); and

      WHEREAS, XL, Acquisition and the Company wish to have the Executive
continue his employment under the Agreement through the consummation of the
merger transactions contemplated by the Merger Agreement (such consummation date
hereafter referred to as the "CIC DATE") and thereafter, as modified in certain
respects, and the Executive wishes to continue such employment.

      NOW, THEREFORE, in consideration of the foregoing, the mutual covenants
and agreements contained herein and other good and valuable consideration, the
parties hereto hereby agree to continue Executive's employment in accordance
with the terms of the Agreement, which continues in full force and effect, and
hereby amend and restate the Agreement in its entirety as follows effective as
of the CIC Date:

      1. CERTAIN DEFINED TERMS. In addition to terms defined elsewhere herein,
the following terms shall have the following meanings when used in this
Agreement with initial capital letters:

      (a) "ANNUAL INCENTIVE PLAN" shall mean: (i) prior to the CIC Date, the NAC
Re Corp. Amended and Restated Annual Incentive Plan ("NAC RE AIP") as referred
to in Exhibit 10.11 of the NAC Re Corp. 1997 Annual Report on Form 10-K ("FORM
10-K"); following the CIC Date and prior to February 28, 2002, either the NAC Re

      (b) "BOARD" shall mean, prior to the CIC Date, the Board of Directors of
NAC Re Corp., and following the CIC Date, the Board of Directors of XL and the
Board of Directors of XL America, Inc.

      (c) "CAUSE" shall mean Executive's willful breach of duty in the course of
his employment or Executive's habitual neglect of his employment duties in a
manner that materially impacts the business or reputation of Employer unless
such breach or neglect is of a nature that reasonably can be corrected and is
corrected within sixty (60) days following written notice to Executive in
respect thereof. For purposes of this Section 1(c), no act or failure to act on
Executive's part shall be deemed "willful" unless done, or omitted to be done,
by Executive not in good faith and without reasonable belief that his action or
omission was in the best interest of Employer. Notwithstanding the foregoing,
Executive shall not be deemed to have been terminated for Cause unless and until
there shall have been delivered to Executive a copy of a resolution duly adopted
by the affirmative vote of not less than three-quarters (3/4) of the entire
membership of the Board at a meeting of the Board called and held for such
purpose (after reasonable notice to Executive and an opportunity for Executive,
together with Executive's counsel, to be heard before the Board), finding that,
in the good faith opinion of the Board, Executive was guilty of conduct set
forth above in this Section 1(c) and specifying the particulars thereof in
detail.

      (d) "CHANGE IN CONTROL" shall mean, through the CIC Date, a change in
control of NAC Re Corp. A Change in Control of NAC Re Corp. shall be deemed to
have occurred on the CIC Date.

      In the event XL has, as of the CIC Date, or thereafter enters into, with
any of its senior executives agreements with respect to the change in control of
XL which provide for greater benefits than due under Section 7(c) hereof in such
situation on a change in control of XL, a similar agreement shall be offered to
Executive to receive such amounts in lieu of the amounts due hereunder.

      (e) "CODE" shall mean the Internal Revenue Code of 1986, as amended.

      (f) "COMMON STOCK," prior to the CIC Date, shall mean the common stock,
ten cents (104) par value, of NAC Re Corp., and after the CIC Date, shall mean
the common stock, one cent ($.01) par value, of XL Capital Ltd.

      (g) "COMPENSATION" shall mean the sum of (i) Executive's annual base
salary pursuant to Section 5(a) hereof and (ii) Executive's annual bonus at
target pursuant to Section 5(b) hereof.

      (h) "COMPENSATION COMMITTEE" shall mean the Compensation Committee of the
Board.

<PAGE>

      (i) "DISABILITY" shall mean permanent and total disability as such term is
defined in the Employer's long term disability plan in effect on the Effective
Date. Any question as to the existence of Disability upon which Executive and
Employer cannot agree shall be determined by a qualified independent physician
selected by Executive (or, if Executive is unable to make such selection, such
selection shall be made by any adult member of Executive's immediate family or
Executive's legal representative), and approved by Employer, said approval not
to be unreasonably withheld. The determination of such physician made in writing
to Employer and to Executive shall be final and conclusive for all purposes of
this Agreement.

      (j) "EFFECTIVE DATE" shall mean June 10, 1998. This Amendment and
Restatement of the Employment Agreement shall be effective as of the CIC Date.

      (k) "FINAL AVERAGE COMPENSATION" shall mean Executive's highest average
annual Compensation earned during any consecutive thirty-six (36) complete
months (or lesser actual period of receiving Compensation) during the period of
sixty (60) complete months (or lesser actual period of receiving Compensation)
immediately preceding Executive's termination of employment with Employer.

      (l) "GOOD REASON" shall mean, for all purposes other than with respect to
all restricted Common Stock which has been issued to Executive but is unvested
as of the CIC Date and all options to acquire Common Stock or stock appreciation
rights ("SARS") which have been granted to Executive but remain unvested as of
the CIC Date (the "EXECUTIVE EQUITY RIGHTS"), the occurrence, without (other
than with respect to (iv)) Executive's express written consent, of any of the
following circumstances:

            (i) the assignment to Executive of any duties inconsistent with his
      offices and status as of the Effective Date (or any offices and status to
      which Executive has been promoted at the time), or a substantial
      diminution in the nature or status of Executive' s responsibilities (other
      than as the result of the Company no longer being a public company);

            (ii) the failure of Employer to retain Executive as Chief Executive
      Officer of NAC Re or in any other capacities set forth in Section 2 hereof
      or a failure to maintain Executive as the most senior executive with
      regard to the operations of XL, Employer and their affiliates in North
      America with the powers, authorities and duties commensurate with such
      positions, subject to Executive's obligations to report to the CEO of XL
      (in his capacity as Executive Vice President of XL), the Board of
      Employer, the Board of Directors of XL and the Board of Directors of XL
      America, Inc.;

<PAGE>
                                      -4-


            (iii) a reduction in Executive's annual base salary as in effect on
      the Effective Date, on January 1, 1999, or as the same may be increased
      from time to time;

            (iv) an election by the Executive, on at least 30 days' written
      notice given at any time after July 31, 2001, to terminate his employment
      between September 1, 2001, and February 28, 2002 inclusive, for any reason
      (or no reason);

            (v) the relocation of the office in which Executive is located on
      the Effective Date to a location more than forty-five (45) miles
      therefrom;

            (vi) a material reduction in the aggregate benefits and compensation
      provided to Executive under employee pension and welfare benefit plans and
      incentive compensation, stock option and stock ownership plans from that
      which existed immediately prior to the CIC Date, or a failure to provide
      cash and equity incentives at a level comparable to similarly situated
      executives of XL;

            (vii) the failure of Employer to obtain a satisfactory agreement
      from any successor (other than any successor resulting from the
      transactions contemplated by the Merger Agreement) to assume and agree to
      perform this Agreement, as contemplated in Section 11 hereof;

            (viii) termination of Executive's employment as a result of his
      death or Disability prior to March 1, 2002;

            (ix) any purported termination of Executive's employment by Employer
      for Cause for which Executive is not given notice of such termination in
      accordance with Section 1(c) hereof; for purposes of this Agreement, no
      such purported termination shall be effective;

            (x) any other material breach of this Agreement by Employer or XL,
      including but not limited to any material breach of Section 2(b) hereof;

            (xi) Brian O'Hara ceasing to be Chief Executive Officer of XL, Brian
      O'Hara not being Chief Executive Officer of the parent entity in the group
      of entities controlling, controlled by, or under common control with XL,
      or Executive being required to report to anyone other than the Chief
      Executive Officer of XL (in Executive's capacity as Executive Vice
      President of XL), the Board of the Employer, the Board of Directors of XL
      or the Board of Directors of XL America, Inc.;

            (xii) the failure of either Employer or XL to make normal equity
      grants to Executive for 1999 in accordance with past practices of NAC Re
      and XL, as the case may be, based on Executive's level of position;
      provided, however, that such

<PAGE>
                                      -5-


      XL grant may be reduced by a number of shares equal to the product of (A)
      the number of shares subject to the 1999 NAC Re grant (as converted to XL
      options) multiplied by (B) a fraction, the numerator of which shall be the
      number of days from the date of the 1999 XL grant through the first
      anniversary of the 1999 NAC Re grant and the denominator of which shall be
      365.

      Notwithstanding anything in this Section 1(l) to the contrary, neither of
the following shall constitute "GOOD REASON": (A) any diminution of duties
resulting from the fact that NAC Re ceases to be a publicly traded, independent
reinsurance company as a result of the consummation of the transactions
contemplated by the Merger Agreement, and (B) any change in duties resulting
from failure to continue the Executive as Co-Chairman, or Chairman, of the
management committees specified in Section 2(d) of this Agreement if such
committees are discontinued, provided that he is offered similar titles and
responsibilities with the replacements (if any) therefor.

      Executive's continued employment shall not constitute consent to, or a
waiver of rights with respect to, any circumstance constituting Good Reason
hereunder. Executive may terminate his employment for Good Reason (other than
pursuant to paragraphs (ii), (iv) (v) or (viii), with regard to which the
remainder of this paragraph shall not apply) only if Executive shall provide the
Company with not less than sixty (60) days' written notice of intent to
terminate for Good Reason, which notice shall set forth in reasonable detail the
facts and circumstances claimed to provide the basis for Executive's termination
for Good Reason, and the Company shall not have cured or remedied its violation
within sixty (60) days following its receipt of such written notice. If within
sixty (60) days following the date on which such notice of termination is given,
Employer notifies Executive that a dispute exists concerning the grounds for
termination, the date of termination for determining the timing of any
obligation under this Agreement shall be the date on which the dispute is
finally determined, either by mutual written agreement of the parties or by
arbitration pursuant to Section 15 hereof; provided, further, that the date of
termination shall be extended by a dispute only if such notice of dispute is
given in good faith and Employer pursues the resolution of such dispute with
reasonable diligence. Notwithstanding the pendency of any such dispute, Employer
will continue to pay Executive his full Compensation in effect when the notice
giving rise to the dispute was given (including, but not limited to, annual base
salary) and continue Executive as a participant in all other incentive
compensation, benefit and insurance plans in which Executive was participating
when the notice giving rise to the dispute was given, until the dispute is
finally resolved in accordance with this Section 1(1), unless resolution of such
dispute is unreasonably delayed by Executive. Amounts paid under this Section
1(1) are in addition to all other amounts due under this Agreement and shall not
be offset against or reduce any other amounts due under this Agreement.

      Notwithstanding the above, for all purposes relating to the Executive
Equity Rights (as such term is defined in this Section 1(l), the definition of
"GOOD REASON" shall not be amended as of the CIC Date but shall remain as
defined prior to this amendment and restatement, which definition is set forth
in Appendix "A" to this Amended and Restated Employment Agreement.

      (m) "GRANT DATE" shall mean the date on which the Board or the
Compensation Committee approves the grant of a non-qualified option to purchase
Common Stock (or a stock appreciation right) or the award of restricted Common
Stock to Executive

      (n) "LONG-TERM INCENTIVE PLAN" shall mean: (i) with respect to grants made
thereunder prior to the CIC Date, the NAC Re Corp. Long-Term Incentive Plan
("NAC RE LTIP") as referred to in Exhibit 10.12 to the Form 10-K; (ii) with
respect to grants made thereunder following the CIC Date and prior to February
28, 2002, either the NAC Re LTIP or the long-term incentive plan maintained by
XL for its senior executives ("XL LTIP"), as designated by Executive prior to
November 1 of each year; and (iii) with respect to grants made thereunder on or
after February 28, 2002, the XL LTIP.

      (o) "TERM" shall mean the term provided in Section 4 hereof.

      (p) "CIC DATE" shall mean the consummation date of the merger transactions
referred to in the Merger Agreement.

      (q) "MATERIAL CAUSE" shall mean Executive's willful (as defined in Section
1(c)) actions or inactions intended to result in material damage to XL or the
Employer. Notwithstanding the foregoing, Executive shall not be deemed to have
been terminated for Material Cause unless and until there shall have been
delivered to Executive a copy of a resolution duly adopted by the affirmative
vote of not less than three-quarters (3/4) of the entire membership of the Board
at a meeting of the Board called and held for such purpose (after reasonable
notice to Executive and an opportunity for Executive, together with Executive's
counsel, to be heard before the Board), finding that, in the good faith opinion
of the Board, Executive was guilty of conduct set forth above in this Section
1(q) and specifying the particulars thereof in detail.

      (r) "MERGER AGREEMENT" shall mean the Agreement and Plan of Merger among
XL Capital Ltd ("XL"), NAC Re Acquisition Corp. ("ACQUISITION"), and NAC Re
Corporation ("NAC RE") dated as of February 15, 1999.

      2. EMPLOYMENT; DUTIES.

Employer's, XL's and their affiliates' most senior executive with regard to

insurance and reinsurance operations in North America (subject to his
obligations to report to the CEO of XL (in his capacity as Executive Vice
President of XL), the Board of the Employer, the Board of XL and the Board of XL

      (b) As CEO of XL America, Inc., Executive will have management and profit
and loss responsibility for all current and future North American property and
casualty insurance and reinsurance operations and related service businesses
except to the extent that all or part of such responsibility is allocated to
other executives of XL or its subsidiaries with the express written consent of
Executive. As CEO of XL America, Inc. and NAC Re, Executive will have full
management and supervisory responsibility for all current and future employees
of XL America, Inc. and NAC Re and NAC Re's principal operating subsidiaries,
except to the extent such responsibilities are reasonably delegated to others or

                                      measurement periods ending after
                                      January 1, 1999 - 60% (0-120%

              (ii)   XL LTIP:         comparable to that of other senior
                                      executives of comparable position at XL.

      (d) Special Stock Option Grant:

            (i) On or prior to the Effective Date, Executive shall be granted
      stock appreciation rights ("SARS"), which will automatically convert into
      non-qualified options on November 11, 1998, with respect to one hundred
      and twenty five thousand (125,000) shares of Common Stock, twenty percent
      (20%) of which shall vest on each of the five (5) anniversaries of the
      Grant Date, provided that Executive is employed by Employer on those
      dates. The exercise price of the foregoing SARs shall be the fair market
      value of a share of Common Stock on the Grant Date.

            (ii) Nothing herein shall have the effect of modifying or
      superseding the terms of any SARs or stock option grants or restrictive
      stock grants to which the Executive may be entitled pursuant to his prior
      employment contract.

            (iii) Options or SARs granted pursuant to this Agreement shall be
      subject to the terms and conditions of the Company's stock option plans

      Date.

<PAGE>
                                      -9-


            (iv) Upon the consummation of the merger transactions contemplated
      by the Merger Agreement, each outstanding stock option into which an SAR
      granted under this section shall have been converted, and all other
      outstanding SAR, stock option, or restricted stock grants then held by
      Executive or to which he may then be entitled pursuant to a prior
      employment contract, shall be deemed to constitute an option or other
      equity grant with respect to common stock of XL Capital, Ltd upon the
      terms set forth in Section 1.6 of the Merger Agreement.

      To the extent necessary to cause the condition set forth in Section 6.1(g)
of the Merger Agreement to be satisfied, the Executive hereby waives the rights
he may have, if any, to receive a lump sum cash amount with respect to any
outstanding Stock Options.

      (e) Annual Stock Option Grant: Executive shall be given the opportunity to
be granted additional options or SARs with respect to shares of Common Stock
with an underlying market value at the time of grant of 100-125% of Executive's
annual base salary at the time of grant in accordance with and commencing upon
Employer's next regular grant of options following the Effective Date; provided,
however, that nothing contained in this Section 5(f) shall confer upon Executive
any right to such additional options or SARs. Following the CIC Date, any
opportunity for a grant of options or other equity grants, including grants of
SARs and restricted stock, will be in respect of common stock of XL Capital Ltd,
in accordance with the terms set forth in Section 1.6 of the Merger Agreement
and the relevant plans and policies of XL applicable to senior executives of XL
at a level comparable to Executive; provided, however, that nothing contained in
this Section 5(e) shall confer upon Executive any right to such options or other
equity grants.

      (f) Supplemental Retirement Benefit:

            (i) If Executive's employment terminates with Employer and its
      affiliates on or after his attaining age fifty (50), Executive shall be
      paid a lifetime annual retirement benefit, commencing within thirty (30)
      days following the date of such retirement, equal to fifty percent (50%)
      of Executive's Final Average Compensation, reduced by benefits from any
      defined benefit pension plans maintained by Employer or its affiliates and
      any defined benefit pension plans maintained by any previous employers.
      Any retirement benefit that is payable prior to age sixty (60) shall be
      reduced by five percent (5%) per year for each year prior to age sixty
      (60); e.g. at age fifty (50) the benefit would equal twenty five percent
      (25%) of Executive's Final Average Compensation. The benefit will be paid
      to Executive for his lifetime and, upon his death, fifty percent (50%) of
      his benefit will be paid to his surviving spouse, if any, for her
      lifetime. In the event of the Executive's death after age fifty (50) but
      prior to retirement, a benefit shall be paid to the Executive's surviving
      spouse, if any, for her lifetime

<PAGE>
                                      -10-


      equal to the benefit which would have been payable to the spouse assuming
      Executive had retired the day preceding the date of death and then died.

            (ii) If Executive's employment terminates with Employer and its
      affiliates during the term of this contract but prior to his attaining age
      fifty (50), for the purpose of allowing Executive to vest in the
      retirement benefit as set forth in (i) above, Employer or its affiliates
      shall provide Executive with additional service credit, in addition to
      actual service credit for purposes of determining the eligibility for the
      retirement benefit in subsection (i), above, equal to four (4) years
      service credit plus service credit equal to the greater of three (3) years
      credit or credit for the balance of the contract term. In the event of
      Executive's death during the term of this contract but prior to attaining
      age fifty (50), a benefit shall be paid to the Executive's surviving
      spouse, if any, assuming the Executive had terminated employment the day
      preceding the date of his death and then died.

            (iii) (1) If Executive's employment terminates with Employer and its
      affiliates due to his Disability, a supplemental disability benefit shall
      be payable under the terms of this Agreement. The amount of such
      supplemental disability benefit shall equal the difference between (x)
      fifty percent (50%) of Executive's Final Average Compensation and (y) the
      benefit received by Executive under the long term disability plan of
      Employer or its affiliates. Such supplemental benefit shall be payable at
      the same time and under the same terms as the long term disability plan
      benefit. This supplemental disability benefit shall cease when benefits
      under the long term disability plan cease.

            (iv) (2) Upon cessation of disability benefits at age sixty-five
      (65), the Executive will become eligible for a retirement benefit under
      paragraph (i) of this Section 5 (f). In the event supplemental disability
      benefits cease prior to age (65) and the Executive does not return to work
      with the Company or its affiliates, for purposes of this Section 5 (f) the
      Executive shall be considered to have terminated employment or died, as
      appropriate, as of the date supplemental disability benefits ceased.

            (v) The calculation of the benefits payable pursuant to this Section
      5(f) shall be performed by the actuary for the defined benefit pension
      plan(s) of the Employer or its affiliates, if any, otherwise by an
      independent actuary selected by the Employer or its affiliates, whose
      calculation shall be final and binding on all persons. The benefits
      payable pursuant to this Section 5(f) shall be unfunded and the Executive
      will not be considered to have received a taxable economic benefit prior
      to the time at which benefits are actually payable hereunder. Accordingly,
      the Employer or its affiliates shall not be required to segregate any of
      its assets for the benefit of the Executive

<PAGE>
                                      -11-


      and the Executive shall have only a contractual right against the Employer
      or its affiliates for the benefits payable hereunder.

      (g) Relocation: Employer has relocated Executive to New Canaan,
Connecticut in accordance with Employer's relocation policy. As such, Employer
has agreed to pay to Executive a mortgage subsidy of $20,260 per year through
December 2002. Employer shall pay to Executive, with respect to any payments in
connection with relocation that are subject to federal, state or local taxation,
an additional amount so that Executive shall incur no such taxes with respect to
such payments.

      (h) Pension and Welfare Benefit Programs: Executive shall be entitled to
participate, on a basis and to the extent consistent with Executive's senior
executive position (and on a basis no less favorable than other senior
executives), in any employee pension or welfare benefit plan, employee stock
purchase plan and other so-called fringe benefit programs from time to time in
effect for the benefit of employees of Employer generally and/or for any group
of employees of which Executive is a member, provided that Executive meets the
eligibility requirements of any such plan or program. Executive shall continue
to receive short-term and long-term disability coverage, life insurance, medical
insurance and dental insurance reasonably comparable to that in effect as of the
Effective Date.

      (i) Other Executive Benefits: (1) During the Term, Employer shall (i)
provide Executive with an automobile of a make and model commensurate with
Executive's position and shall pay all costs of insurance, maintenance and
operation for such automobile; (ii) provide Executive with reasonable financial
planning and tax services; and (iii) reimburse Executive for reasonable club
dues and initiation fees at a club of Executive's choice which is important to
the conduct of the business of Employer and which is used for business purposes.

            (2) During the Term, Employer shall, subject to Executive's
reasonable cooperation in doing so, obtain and pay all costs of a life insurance
policy in the amount of $4,000,000 with respect to which Executive shall be the
insured and shall have the right to designate a beneficiary, and shall fully
gross up Executive for any income tax on the provision of such life insurance
and the gross-up payment.

            (3) During the Term through February 28, 2002, Employer, through
insurance or out of its own assets, shall provide that Executive shall receive a
lump sum payment of $4,000,000 at such time as he shall incur a Disability for
the first time and shall fully gross up Executive for any income taxes on the
providing of such benefit (other than on the payment of the benefit) and the
gross-up payment.

      (j) VACATION: During the Term, Executive shall be entitled to no less than
five (5) weeks paid vacation per year.

<PAGE>
                                      -12-


      (k) SIGNING BONUS: Upon the execution of this Amended and Restated
Employment Agreement and consummation of the merger transaction contemplated by
the Merger Agreement, Executive shall be entitled to a special sign-on bonus in
the amount of $1,000,000, which shall be paid as soon as practicable thereafter.

      6. OTHER ACTIVITIES. During the Term, Executive is expected to devote to
Employer's business his full business time and attention so as to assure full
and efficient performance of Executive's duties hereunder. During the Term,
Executive shall not, without Employer's prior written consent, engage or
participate, directly or indirectly, in any other business as a sole proprietor,
partner, employee, officer, shareholder, trustee, paid advisor or paid
consultant or accept appointment or election as a director or in any other
fiduciary or honorary capacity in any other business, venture or project;
provided, however, that nothing in this Agreement shall preclude Executive from
devoting nonbusiness time and efforts to charitable, social and civic matters to
the extent that such activities do not interfere with Executive's performance of
his duties under this Agreement and provided, further, however, that Executive
shall not be precluded from making investments as described in the proviso to
the first sentence of Section 8(a) hereof.

      7. TERMINATION. Executive's employment under this Agreement may be
terminated by Employer at any time without prior notice, subject to the
requirement of prior notice if such termination is for Cause. Executive's
employment under this Agreement may be terminated by Executive upon not less
than two (2) months' prior notice, other than in the case of termination on
account of Executive's unforeseen health problems, Disability or Good Reason. If
Executive's employment under this Agreement is terminated, the following
provisions shall apply:

      (a) Termination of Employment after February 28, 2002 by Employer for a
Reason other than Cause or by Executive for Good Reason: If, before the end of
the Term and after February 28, 2002, Employer terminates Executive's employment
for a reason other than Cause, or if Executive terminates employment on account
of Good Reason, Employer shall pay to Executive, within thirty (30) days
following the date of such termination, a lump sum amount equal to the sum of
(i) Executive's then annual base salary plus (ii) the amounts that would be paid
to Executive under the Annual Incentive Plan and the Long-Term Incentive Plan at
Executive's targets for the year or performance period, as the case may be,
during which such termination occurs, which sum is multiplied by three (3).

      (b) Termination of Employment after February 28, 2002, by Employer for
Cause, by Executive other than for Good Reason, or on account of Death or
Disability, or at any time by Employer for Material Cause: If Executive's
employment is terminated (i) after February 28, 2002, by Employer for Cause, by
Executive other than for Good Reason, or on account of Executive's death or
Disability, or (ii) by Employer at any time for Material Cause,

<PAGE>
                                      -13-


Executive, or his estate in the case of his death, shall receive from Employer,
within thirty (30) days following the date of termination, a lump sum amount
equal to Executive's annual base salary which is accrued but unpaid as of the
date of termination and any amounts, if any, due under Sections 5(i)(2) and (3)
hereof.

      (c) Termination of Employment as a result of Death or Disability, by
Employer other than for Cause or Material Cause, or by Executive for Good
Reason, in each case prior to March 1, 2002: (1) If, prior to March 1, 2002,
Executive's employment is terminated as a result of death or Disability, by
Employer other than for Material Cause, or by Executive for Good Reason,
Employer shall pay to Executive, within thirty (30) days following such
termination, a lump sum amount equal to the sum of (w) Executive's annual base
salary which is accrued but unpaid as of the date of termination, plus (x) the
portions, if any, of amounts under the Annual Incentive Plan and Long-Term
Incentive Plan that were earned by Executive but unpaid as of the date of
termination, which, in the event bonuses are discretionary, will be determined
in good faith, without regard to the termination, based on the level of bonuses
for comparable executives, plus (y) the greater of 2.99 and the number of years
including fractions thereof, remaining from the CIC Date until June 30, 2003,
times the sum of (I) Executive's then annual base salary plus (II) the amounts
that would be paid to Executive under the Annual Incentive Plan and the
Long-Term Incentive Plan at Executive's targets as in effect immediately prior
to the CIC Date, as increased until the date of payment of the amount described
above in this Section 7(c)(y), at an annual compounded rate of 8%, plus (z) any
amounts, if any, due under Sections 5(i)(2) and (3) hereof. In no event shall
the sums of (I) and (II) be less than $1,218,250.

            (2) In addition, if, prior to March 1, 2002, Executive's employment
is terminated by Employer other than for Cause (but not as a result of death or
Disability) or by Executive for Good Reason, Executive shall vest in all issued
but unvested restricted Common Stock and granted but unvested options to acquire
Common Stock or stock appreciation rights then held by Executive. The parties
acknowledge that solely for purposes of this Section 7(c)(2) (but not any other
part of this Section 7), Executive's rights to terminate for Good Reason
pursuant to Section (l)(iv) of Appendix A as a result of the consummation of the
merger transactions contemplated by the Merger Agreement are not waived and
shall continue throughout the Term.

      (d) Non-Exclusivity of Rights: Nothing in this Agreement shall prevent or
limit Executive's present or future participation in any benefit, bonus,
incentive, or other plan or program provided by Employer for which Executive may
qualify, nor shall this Agreement limit or otherwise affect rights that
Executive may have under any stock option or other agreements with Employer.
Amounts or benefits that are vested or that Executive is otherwise entitled to
receive under any plan or program of Employer at, or subsequent to, the date of
termination of Executive's employment shall be payable in accordance with such
plan or pro-

<PAGE>
                                      -14-


gram; provided, however, that any compensation and benefits received by
Executive pursuant to this Agreement shall be in lieu of (but, if necessary to
give effect to this provision, shall be reduced by) any and all compensation and
benefits that Executive is entitled to receive or may become entitled to receive
under any reduction in force or severance pay plan, program or practice that
Employer now has in effect or may hereafter put into effect and shall be applied
toward satisfying any severance pay and benefits required under federal or state
law to be paid or provided to Executive.

      (e) Excise Tax Gross Up: If an excise tax under Section 4999 of the Code
or any comparable tax that is in excess of ordinary federal income taxes, as may
be in effect from time to time, is imposed on amounts paid to Executive
hereunder, or otherwise in connection with or relating to the transactions
contemplated by the Merger Agreement or any future transaction involving XL or
its affiliates, then Executive shall be reimbursed by Employer in an amount
equal to such excise tax and any further tax due on amounts reimbursed
hereunder, upon request, at th1e time Executive is required to make a payment
thereof.

      8. NON-COMPETITION; CONFIDENTIAL INFORMATION.

      (a) Executive agrees that during the Term, and if Executive's employment
is terminated by Executive other than for Good Reason, for a period of twelve
(12) months following the date of termination of this Agreement, Executive shall
not (i) engage anywhere within the geographical areas in which NAC Re Corp. and
its subsidiaries or affiliates (for purposes of this Section 8, the "NAC RE
GROUP") have conducted their business operations as of the Effective Date or at
any time prior to the date of termination of Executive's employment directly or
indirectly, alone or as a shareholder, principal, agent, partner, officer,
director, employee or consultant of any other organization, in the business
conducted by the NAC Re Group as a material component of its reinsurance
operations, in direct competition with the NAC Re Group; provided, however, that
it is acknowledged and agreed that this Section 8(a)(i) does not prohibit
Executive from engaging in the reinsurance business where the Executive is only
incidentally engaged in any activity which is a material component of the
operations of the NAC Re Group; and Executive further agrees that during the
Term, and if Executive's employment is terminated by Executive other than for
Good Reason, for a period of twenty-four (24) months following the date of
termination of this Agreement Executive shall not (ii) divert to any competitor
of the NAC Re Group any customer of the NAC Re Group; provided, however, that
Executive may invest in stocks, bonds, or other securities of any similar
business (but without otherwise participating in such similar business) if (A)
such stocks, bonds, or other securities are listed on any national or regional
securities exchange or have been registered under Section 12(g) of the Exchange
Act; and (B) his investment does not exceed, in the case of any class of the
capital stock of any one issuer, one percent (1%) of the issued and outstanding
shares, or, in the case of other securities, one percent (1%) of the aggregate
principal amount thereof issued and outstanding. If at any time the provisions
of

<PAGE>
                                      -15-


this Section 8 shall be determined to be invalid or unenforceable, by reason of
being vague or unreasonable as to area, duration or scope of activity, this
Section 8 shall be considered divisible and shall become and be immediately
amended to only such area, duration and scope of activity as shall be determined
to be reasonable and enforceable by the court or other body having jurisdiction
over the matter; and Executive agrees that this Section 8, as so amended, shall
be valid and binding as though any invalid or unenforceable provision had not
been included herein. Nothing in this Section 8 shall prevent or restrict
Executive from engaging in any business or industry other than those designated
herein in any capacity.

      (b) Executive also agrees that, during the Term, and if Executive's
employment is terminated by Executive other than for Good Reason, for a period
of twenty-four (24) months following the date of termination of this Agreement,
Executive shall not solicit any officer, employee or consultant of the NAC Re
Group to leave their employ for other employment;

      (c) Executive shall not at any time after the date of termination of
employment reveal to anyone other than authorized representatives of the NAC Re
Group, or use for Executive's own benefit, any trade secrets, customer
information or other information that has been designated as confidential by the
NAC Re Group or is understood by Executive to be confidential without the
written authorization of the Board in each instance, unless such information is
or becomes available to the public or is otherwise public knowledge or in the
public domain for reasons other than Executive's acts or omissions.

      (d) If Executive materially breaches any of the obligations under this
Section 8, Employer shall have no further compensation or benefit obligations
pursuant to this Agreement or pursuant to the Annual Incentive Plan or the
Long-Term Incentive Plan but shall remain obligated for compensation and
benefits for periods prior to such breach as provided in any other plans,
policies or practices then applicable to Executive in accordance with the terms
thereof. Executive hereby acknowledges that Employer's remedies at law for any
breach of Executive's obligations under this Section 8 would be inadequate, and
Executive and Employer agree that in addition to any other remedies provided for
herein or otherwise available at law, temporary and permanent injunctive relief
may be granted in any proceeding which may be properly brought by Employer to
enforce the provisions of this Section 8 without the necessity of proof of
actual damages.

      9. NO MITIGATION OBLIGATION; NO SET-OFF OR COUNTERCLAIMS. In no event
shall Executive be obligated to seek other employment by way of mitigation of
the amounts payable to Executive under any of the provisions of this Agreement.
Any amounts that may be earned by Executive other than from Employer shall not
reduce Employer's obligation to make any payments hereunder. The amounts payable
by Employer hereunder shall not be subject to any right of set-off that Employer
may assert against Executive.

<PAGE>
                                      -16-


10. TAXES. Employer may withhold from any amounts payable under this Agreement
all federal, state, city, or other taxes as Employer is required to withhold
pursuant to any law, regulation or ruling. Executive shall bear all expense of,
except as otherwise contemplated herein, and be solely responsible for, all
federal, state, local or foreign taxes due with respect to any payment received
hereunder.

      11. SUCCESSORS AND BINDING AGREEMENT.

      (a) Employer will require any successor, whether direct or indirect, by
purchase, merger, consolidation or otherwise to all or substantially all of the
business and/or assets of Employer, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that Employer is
required to perform it. Failure of Employer to obtain such assumption and
agreement prior to the effectiveness of any such succession shall be a breach of
this Agreement and shall entitle Executive to compensation from Employer in the
same amount and on the same terms as Executive would be entitled hereunder if
Executive had terminated his employment for Good Reason following a Change in
Control, except that for purposes of implementing the foregoing, the date on
which any such succession becomes effective shall be deemed the date on which
Executive's employment with Employer was terminated. As used in this Agreement
"Employer" shall include any successor to Employer's business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise. Except as provided above, Employer may not assign this
Agreement. As of the CIC Date, XL agrees to guarantee payment of the obligations
of the Employer under this Agreement. Such guarantee shall be a guarantee of
payment, not collections. With respect to such guarantee, XL and Executive agree
to resolve any disputes as provided in Section 15 hereof and as part of the same
arbitration in which Executive and Employer participate.

      (b) This Agreement shall inure to the benefit of, and be enforceable by,
Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If Executive dies while
any amount is still payable hereunder, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement to
Executive's devisee, legatee or other designee or, if there is no such designee,
to Executive's estate.

      12. NOTICES. For the purpose of this Agreement notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
registered mail, return receipt requested, postage prepaid, addressed to the
respective addresses set forth below, provided that all notices to Employer
shall be directed to the attention of the Office of the General Counsel of NAC
Re Corp., or to such other address as either party may have furnished to the

principles of conflict of laws of such State, to the extent not preempted by
applicable federal law.

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

      15. ARBITRATION. Any dispute arising out of or in any way relating to this
Agreement or Executive's employment with Employer, including, without

the arbitrators and the other arbitration costs, if Executive should prevail on
any material matter in the arbitration.

      16. MERGER. This Agreement (coupled with other ancillary written
agreements to which Employer and Executive are a party such as stock option and
restricted stock agreements) expresses in full the understanding of Employer and
Executive, and all promises, representations, understandings, arrangements and
prior agreements with regard to Executive's employment by Employer are merged
herein.

      17. WAIVER. Failure by either party hereto to insist upon strict adherence
to any one or more of the covenants or terms contained herein, on one or more
occasions, shall not be construed to be a waiver nor deprive such party of the
right to require strict compliance with the same thereafter.

      18. AMENDMENTS. No amendments hereto, or waivers or releases of
obligations or liabilities hereunder, shall be effective unless agreed to in
writing by all parties hereto.

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

      20. INDEMNIFICATION. XL and the Employer shall indemnify and hold
Executive harmless to the fullest extent permitted by applicable law with regard
to any action or inaction taken by Executive as a director or officer of
Employer or XL or the affiliates of either following the CIC Date. XL and

      As stated in Section 1(l) of the Agreement, for all purposes with respect
to the Executive Equity Rights (as such term is defined in Section 1(l) of the
Agreement), the definition of "GOOD REASON" shall remain as set forth in Section
1(l) of the Agreement prior to the execution of this Amended and Restated
Employment Agreement, which definition is set forth below:

            A(l) "GOOD REASON" shall mean the occurrence, without Executive's
      express written consent, of any of the following circumstances unless, in
      the case of paragraphs (i), (vi), (vii), (viii) or (ix), such
      circumstances are fully corrected within sixty (60) days following
      Executive's written notice to Employer in respect thereof:

                  A(i) the assignment to Executive of any duties inconsistent
            with his offices and status as of the Effective Date (or any offices
            and status to which Executive has been promoted at the time), or a
            substantial diminution in the nature or status of Executive's
            responsibilities;

                  A(ii) the failure of Employer to retain Executive as Chief
            Executive Officer of NAC Re Corp. or to appoint Executive as
            Chairman of the Board as set forth in sections 2 and 3 hereof;

                  A(iii) a reduction in Executive's annual base salary as in
            effect on the Effective Date, on January 1, 1999 or as the same may
            be increased from time to time;

                  A(iv) in the event of a Change in Control, any circumstances
            in which Executive is not Chief Executive Officer of a publicly
            traded, independent reinsurance company; for the purposes of this
            provision, "independent reinsurance company" is deemed to mean that
            a single shareholder or group, other than an investment advisor
            holding shares for others, does not own 20% or more of the Company's
            stock;

                  A(v) the relocation of the office in which Executive is
            located on the Effective Date to a location more than forty-five
            (45) miles therefrom;

                  A(vi) a material reduction in the aggregate benefits and
            compensation provided to Executive under Employer's employee pension
            and welfare benefit plans and incentive compensation, stock option
            and stock ownership plans;


                                      A-1
<PAGE>

                  A(vii) the failure of Employer to obtain a satisfactory
            agreement from any successor to assume and agree to perform this
            Agreement, as contemplated in Section 11 hereof;

                  A(viii) the failure to Employer to offer to renew Executive's
            employment contract, within eighteen (18) months preceding its
            expiration, with terms which are at least as favorable as those set
            forth herein; or

                  A(ix) any purported termination of Executive's employment by
            Employer for Cause for which Executive is not given notice of such
            termination in accordance with Section 1(c) hereof; for purposes of
            this Agreement, no such purported termination shall be effective.

            "EXECUTIVE'S continued employment shall not constitute consent to,
or a waiver of rights with respect to, any circumstance constituting Good Reason
hereunder. In the event of a termination of Executive's employment by Executive
for Good Reason, Executive shall provide Employer not less than sixty (60) days'
notice of such termination. Such notice shall indicate that such termination is
for Good Reason and shall set forth in reasonable detail the facts and
circumstances claimed to provide the basis for Executive's termination for Good
Reason. If within sixty (60) days following the date on which such notice of
termination is given, Employer notifies Executive that a dispute exists
concerning the grounds for termination, the date of termination for determining
the timing of any obligation under this Agreement shall be the date on which the
dispute is finally determined, either by mutual written agreement of the parties
or by arbitration pursuant to Section 15 hereof; provided, further, that the
date of termination shall be extended by a dispute only if such notice of
dispute is given in good faith and Employer pursues the resolution of such
dispute with reasonable diligence. Notwithstanding the pendency of any such
dispute, Employer will continue to pay Executive his full compensation in effect
when the notice giving rise to the dispute was given (including, but not limited
to, annual base salary) and continue Executive as a participant in all other
incentive compensation, benefit and insurance plans in which Executive was
participating when the notice giving rise to the dispute was given, until the
dispute is finally resolved in accordance with this Section 1(l), unless
resolution of such dispute is unreasonably delayed by Executive. Amounts paid
under this Section 1(l) are in addition to all other amounts due under this
Agreement and shall not be offset against or reduce any other amounts due under
this Agreement."

      developed a plan and timetable for addressing the Year 2000 Problem on a

      computer applications of XL Capital and its Subsidiaries that are material
      to its or any of its Subsidiaries' business and operations are reasonably
      expected on a timely basis to be able to perform properly date-sensitive

      Compliant"), except to the extent that a failure to do so could not
      reasonably be expected to have a Material Adverse Effect."

      Agent and the Borrowers, the option to provide to the Borrowers all or any
      part of any Loan that such Designating Lender would otherwise be obligated
      to make to any Borrower pursuant to this Agreement; provided that nothing
      herein shall constitute a commitment by such Designated Lender to make any

      making such Loans or portion thereof would have had under this Agreement
      and otherwise; provided that (i) its voting rights under this Agreement
      shall be exercised solely by its Designating Lender, (ii) its Designating
      Lender shall be deemed to hold its relevant Note as agent for such

      such Designated Lender and (iii) the designation of a Designated Lender
      and the funding of Loans by a Designated Lender shall in no event (x)
      subject any of the Borrowers to any delay in the making of a Loan, (y)
      cause or give rise to any obligation of any of the Borrowers to indemnify
      or hold harmless such Designated Lender or any other Person (including
      without limitation pursuant to Sections 5.05 and 11.03 hereof) except to
      the extent such obligation would have arisen in favor of the Designating
      Lender or another Person if the Designating Lender (rather than such
      Designated Lender) had made all of such Designated Lender's Loans and such
      Designated Lender had not been designated as such hereunder, or (z) render
      the performance of any provisions of the Agreement illegal, void or
      unenforceable under any provision of law. Each Designating Lender shall
      act as administrative agent for its Designated Lender and give and receive
      notices and other communications on behalf of its Designated Lender. Any
      payments for the account of any Designated Lender shall be paid to its
      Designating Lender as administrative agent for such Designated Lender and
      neither the Borrowers nor the Administrative Agent shall be responsible
      for any Designating Lender's application of such payments. In addition,
      any Designated Lender may (i) with notice to, but without the prior
      written consent of, XL Capital and the Administrative Agent and without
      paying any processing fee therefor, assign all or a portion of its
      interests in any Loans to the Designating Lender or to any financial
      institutions (consented to by XL Capital and the Administrative Agent)
      providing liquidity and/or credit support to or for the account of such
      Designated Lender to support the funding or maintenance of Loans and (ii)
      disclose on a confidential basis any non-public information relating to
      its Loans or portions thereof to any rating agency, commercial paper
      dealer or provider of any surety, guarantee or credit or liquidity
      enhancement to such Designated Lender. This Section 11.06(j) may not be
      amended without the written consent of each Designating Lender which has
      designated a Designated Lender."

            "Section 12. Guarantee.

            12.01. The Guarantee. Each Guarantor hereby jointly and severally
      guarantees to each Bank and the Administrative Agent and their respective
      successors and assigns the prompt payment in full when due (whether at
      stated maturity, by acceleration or otherwise) of the principal of and
      interest on the Loans made by the Banks to each of the Borrowers (other
      than such Guarantor in its capacity as a Borrower hereunder) and all other
      amounts from time to time owing to the Banks or the Administrative Agent
      by such Borrowers under this Agreement, in each case strictly in
      accordance with the terms thereof (such obligations being herein
      collectively called the "Guaranteed Obligations"). Each Guarantor hereby
      further jointly and severally agrees that if any such Borrower shall fail
      to pay in full when due (whether at stated maturity, by acceleration or
      otherwise) any of the Guaranteed Obligations, such Guarantor will promptly
      pay the same, without any demand or notice whatsoever, 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.

            12.02. Obligations Unconditional. The obligations of the Guarantors
      under Section 12.01 hereof are absolute and unconditional, joint and
      several, irrespective of the value, genuineness, validity, regularity or
      enforceability of the obligations of the Borrowers under this Agreement or
      any other agreement or instrument referred to herein or 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 that might otherwise constitute a legal or equitable discharge
      or defense of a surety or guarantor, it being the intent of this Section
      12 that the obligations of the Guarantors hereunder shall be absolute and
      unconditional, joint and several, under any and all circumstances. Without
      limiting the generality of the foregoing, it is agreed that the occurrence
      of any one or more of the following shall not alter or impair the
      liability of the Guarantors 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
      this Agreement or any other agreement or instrument referred to herein
      shall be done or omitted; or

                  (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 this Agreement
      or any other agreement or instrument referred to herein 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.

            The Guarantors hereby expressly waive diligence, presentment, demand
      of payment, protest and all notices whatsoever, and any requirement that
      the Administrative Agent or any Bank exhaust any right, power or remedy or
      proceed against any Borrower under this Agreement or any other agreement
      or instrument referred to herein, or against any other Person under any
      other guarantee of, or security for, any of the Guaranteed Obligations.

            12.03. Reinstatement. The obligations of the Guarantors under this
      Section 12 shall be automatically reinstated if and to the extent that for
      any reason any payment by or on behalf of any Borrower 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 or reorganization or otherwise, and the
      Guarantors jointly and severally agree that they will indemnify the
      Administrative Agent and each Bank on demand for all reasonable costs and
      expenses (including fees of counsel) incurred by the Administrative Agent
      or such Bank in connection with such rescission or restoration, including
      any such 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 or similar law.

            12.04. Subrogation. The Guarantors hereby jointly and severally
      agree that until the payment and satisfaction in full of all Guaranteed
      Obligations and the expiration and termination of the Commitments of the
      Banks under this Agreement they shall not exercise any right or remedy
      arising by reason of any performance by them of their guarantee in Section
      12.01 hereof, whether by subrogation or otherwise, against any Borrower or
      any other guarantor of any of the Guaranteed Obligations or any security
      for any of the Guaranteed Obligations.

            12.05. Remedies. The Guarantors jointly and severally agree that, as
      between the Guarantors and the Banks, the obligations of the Borrowers
      under this Agreement may be declared to be forthwith due and payable as
      provided in Section 9 hereof (and shall be deemed to have become
      automatically due and payable in the circumstances provided in Section 9
      hereof) for purposes of Section 12.01 hereof notwithstanding any stay,
      injunction or other prohibition preventing such declaration (or such
      obligations from

<PAGE>
                                      -14-


      becoming automatically due and payable) as against any Borrower and that,
      in the event of such declaration (or such obligations being deemed to have
      become automatically due and payable), such obligations (whether or not
      due and payable by any Borrower) shall forthwith become due and payable by
      the Guarantors for purposes of Section 12.01 hereof.

            12.06. Instrument for the Payment of Money. Each Guarantor hereby
      acknowledges that the guarantee in this Section 12 constitutes an
      instrument for the payment of money, and consents and agrees that any Bank
      or the Administrative Agent, at its sole option, in the event of a dispute
      by such Guarantor in the payment of any moneys due hereunder, shall have
      the right to bring motion-action under New York CPLR Section 3213.

            12.07. Continuing Guarantee. The guarantee in this Section 12 is a
      continuing guarantee, and shall apply to all Guaranteed Obligations
      whenever arising.

            12.08. Rights of Contribution. The Guarantors hereby agree, as
      between themselves, that if any Guarantor shall become an Excess Funding
      Guarantor (as defined below) by reason of the payment by such Guarantor of
      any Guaranteed Obligations, each other Guarantor shall, on demand of such
      Excess Funding Guarantor (but subject to the next sentence), pay to such
      Excess Funding Guarantor an amount equal to such Guarantor's Pro Rata
      Share (as defined below and determined, for this purpose, without
      reference to the properties, debts and liabilities of such Excess Funding
      Guarantor) of the Excess Payment (as defined below) in respect of such
      Guaranteed Obligations. The payment obligation of a Guarantor to any
      Excess Funding Guarantor under this Section 12.08 shall be subordinate and
      subject in right of payment to the prior payment in full of the
      obligations of such Guarantor under the other provisions of this Article
      and such Excess Funding Guarantor shall not exercise any right or remedy
      with respect to such excess until payment and satisfaction in full of all
      of such obligations.

                  For purposes of this Section 12.08, (i) "Excess Funding
      Guarantor" means, in respect of any Guaranteed Obligations, a Guarantor
      that has paid an amount in excess of its Pro Rata Share of such Guaranteed
      Obligations, (ii) "Excess Payment" means, in respect of any Guaranteed
      Obligations, the amount paid by an Excess Funding Guarantor in excess of
      its Pro Rata Share of such Guaranteed Obligations and (iii) "Pro Rata
      Share" means, for any Guarantor, the ratio (expressed as a percentage) of
      (x) the amount by which the aggregate present fair saleable value of all
      properties of such Guarantor (excluding any shares of stock of any other
      Guarantor) exceeds the amount of all the debts and liabilities of such
      Guarantor (including contingent, subordinated, unmatured

<PAGE>
                                      -15-


      and unliquidated liabilities, but excluding the obligations of such
      Guarantor hereunder and any obligations of any other Guarantor that have
      been Guaranteed by such Guarantor) to (y) the amount by which the
      aggregate fair saleable value of all properties of all of the Guarantors
      exceeds the amount of all the debts and liabilities (including contingent,
      subordinated, unmatured and unliquidated liabilities, but excluding the
      obligations of the Guarantors under this Section 12) of all of the
      Guarantors, determined (A) with respect to any Guarantor that is a party
      hereto on the date hereof, as of the date hereof, and (B) with respect to
      any other Guarantor, as of the date such Guarantor becomes a Guarantor
      hereunder.

            12.09. General Limitation on Guarantee Obligations. In any action or
      proceeding involving any state corporate law, or any state or Federal
      bankruptcy, insolvency, reorganization or other law affecting the rights
      of creditors generally, if the obligations of any Guarantor under Section
      12.01 hereof would otherwise, taking into account the provisions of
      Section 12.08 hereof, be held or determined to be void, invalid or
      unenforceable, or subordinated to the claims of any other creditors, on
      account of the amount of its liability under Section 12.01 hereof, then,
      notwithstanding any other provision hereof to the contrary, the amount of
      such liability shall, without any further action by such Guarantor, any
      Bank, the Administrative Agent or any other Person, be automatically
      limited and reduced to the highest amount that is valid and enforceable
      and not subordinated to the claims of other creditors as determined in
      such action or proceeding."

                  a review and assessment of all areas within its and each of
                  its Subsidiaries' business and operations (including those
                  affected by material suppliers, vendors and customers) that
                  could be adversely affected by the risk that computer
                  applications used by XL Capital or any of its Subsidiaries (or
                  material suppliers, vendors and customers other than risks
                  affecting customers that may give rise to claims under
                  insurance policies issued by XL Capital or any Subsidiary of
                  XL Capital) may be unable to recognize and perform properly
                  date-sensitive functions involving certain dates prior to and
                  any date after December 31, 1999 (the "Year 2000 Problem") and
                  (ii) developed a plan and timetable for addressing the Year
                  2000 Problem on a timely basis. Based on the foregoing, XL
                  Capital believes that all computer applications of XL Capital
                  and its Subsidiaries that are material to its or any of its
                  Subsidiaries' business and operations are reasonably expected
                  on a timely basis to be able to perform properly
                  date-sensitive functions for all dates before and after
                  January 1, 2000 ("Year 2000 Compliant"), except to the extent
                  that a failure to do so could not reasonably be expected to
                  have a Material Adverse Effect.

                  applied by such Borrower except as explained in such

                  Report on Form 10-Q filed with the Securities and Exchange
                  Commission shall satisfy the requirement of this Section
                  5.01(b) to deliver the quarterly financial statements of XL
                  Capital so long as the financial information required to be in

by adding at the end thereof a new paragraph (i) to read as follows:

                  detail) that any computer application that is material to its
                  or any of its Subsidiaries' business and operations will not
                  be Year 2000 Compliant (as defined in Section 3.15), except to
                  the extent that such failure could not reasonably be expected
                  to have a Material Adverse Effect.

                        6.09. Claims Paying Ratings. Each of XL Insurance and XL
                  Mid Ocean shall maintain at all times a claims-paying rating

                  A.M. Best Company.

            (k) Section 9.13 of the Credit Agreement is hereby amended by adding
thereto, as a new paragraph (f) thereof, the following:

                        (f) Designated Lenders. Notwithstanding anything to the
                  contrary contained herein, any Bank (a "Designating Lender")
                  may grant to an Eligible Designee identified as such (and as a
                  Designated Lender) in writing from time to time by such
                  Designating Lender to the Administrative Agent and the
                  Borrowers, the option to provide to the Borrowers all or any
                  part of any Loan that such Granting Bank would otherwise be
                  obligated to make to any Borrower pursuant to this Agreement;
                  provided that nothing herein shall constitute a commitment by
                  such Designated Lender to make any Loan and (ii) if a
                  Designated Lender elects not to exercise such option or
                  otherwise fails to provide all or any part of such Loan, the
                  Designating Lender shall be obligated to make such Loan
                  pursuant to the terms hereof. The making of a Loan by a
                  Designated Lender hereunder shall utilize the Committed Amount
                  of the Designating Lender to the same extent, and as if, such
                  Loan were made by such Designating Lender. Each party hereto
                  hereby agrees that no Designated Lender shall be liable for
                  any indemnity or similar payment obligation under this
                  Agreement (all liability for which shall remain with the
                  Designating Lender). In furtherance of the foregoing, each
                  party hereto hereby agrees (which agreement shall survive the
                  termination of this Agreement) that, prior to the date that is
                  one year and one day after the payment in full of all
                  outstanding commercial paper or other senior indebtedness of
                  any Designated Lender, it will not institute against, or join
                  any other person in


                                      -8-
<PAGE>

                  instituting against, such Designated Lender any bankruptcy,
                  reorganization, arrangement, insolvency or liquidation
                  proceedings under the laws of the United States or any State
                  thereof. As to any Loans or portion thereof made by it, each
                  Designated Lender shall have all the rights that a Bank making
                  such Loans or portion thereof would have had under this
                  Agreement and otherwise; provided that (i) its voting rights
                  under this Agreement shall be exercised solely by its
                  Designating Lender, (ii) its Designating Lender shall be
                  deemed to hold its relevant Note as agent for its Designated
                  Lender to the extent of the Loans or portion thereof funded by
                  such Designated Lender and (iii) the designation of a
                  Designated Lender and the funding of Loans by a Designated
                  Lender shall in no event (x) subject any of the Borrowers to
                  any delay in the making of a Loan, (y) cause or give rise to
                  any obligation of any of the Borrowers to indemnify or hold
                  harmless such Designated Lender or any other person (including
                  without limitation pursuant to Sections 2.11 and 9.04 of this
                  Agreement) except to the extent such obligation would have
                  arisen in favor of the Designating Lender or another person if
                  the Designating Lender (rather than such Designated Lender)
                  had made all of such Designated Lender's Loans and such
                  Designated Lender had not been designated as such hereunder,
                  or (z) render the performance of any provision of the
                  Agreement illegal, void or unenforceable under any provision
                  of law. Each Designating Lender shall act as administrative
                  agent for its Designated Lender and give and receive notices
                  and other communications on behalf of its Designated Lender.
                  Any payments for the account of any Designated Lender shall be
                  paid to its Designating Lender as administrative agent for
                  such Designated Lender and neither the Borrowers nor either
                  Agent shall be responsible for any Designating Lender's
                  application of such payments. In addition, any Designated
                  Lender may (i) with notice to, but without the prior written
                  consent of, XL Capital and the Administrative Agent and
                  without paying any processing fee therefor, assign all or a
                  portion of its interests in any Loans to the Designating
                  Lender or to any


                                      -9-
<PAGE>

                  financial institutions (consented to by XL Capital and the
                  Administrative Agent) providing liquidity and/or credit
                  support to or for the account of such Designated Lender to
                  support the funding or maintenance of Loans and (ii) disclose
                  on a confidential basis any non-public information relating to
                  its Loans or portions thereof to any rating agency, commercial
                  paper dealer or provider of any surety, guarantee or credit or
                  liquidity enhancement to such Designated Lender. This section
                  may not be amended without the written consent of each
                  Designating Lender which has designated a Designated Lender.

            (l) In Section 1.01 of the Credit Agreement, the introductory
paragraph of the definition of the term "Indebtedness" is hereby amended to read
as follows:

                  "Indebtedness" of a Person shall mean (it being understood,
                  for the avoidance of doubt, that insurance payment
                  liabilities, as such, and liabilities arising in the ordinary
                  course of such Person's business as an insurance or
                  reinsurance company or corporate member of Lloyds or as a
                  provider of financial services or contracts (in each case
                  other than in connection with the provision of financing to
                  such Person or any of such Person's Affiliates) shall not be
                  deemed to constitute Indebtedness):

            (m)  Section 7.01(e) is hereby amended to read as follows:

                        (e) Any Borrower or any Subsidiary of any Borrower shall
                  default (i) in any payment of principal of or interest on any
                  other obligation for borrowed money in principal amount of
                  $10,000,000 or more or any obligation for borrowed money under
                  the Short Term Revolving Credit Agreement, dated as of June
                  30, 1999, as amended, to which each of the Borrowers is a
                  party, in each case beyond any period of grace provided with
                  respect thereto, or (ii) in the performance of any other
                  agreement, term or condition contained in any such agreement
                  under which any such obligation in principal amount of
                  $10,000,000.00 or more is


                                      -10-
<PAGE>

                  created or contained in such Short Term Revolving Credit
                  Agreement, if the effect of such default is to cause or permit
                  the holder or holders of such obligation (or trustee on behalf
                  of such holder or holders) to cause such obligation to become
                  due prior to its stated maturity or to terminate its
                  commitment under such agreement or to cause or permit the
                  holder or holders of any obligation under such Short Term
                  Revolving Credit Agreement to cause such obligation to become
                  due prior to its stated maturity or to terminate its
                  commitment under such Short Term Revolving Credit Agreement;

            (n) Section 2.01(a) of the Credit Agreement is hereby amended by
adding thereto, as a new last sentence thereof, the following:

                  Notwithstanding anything to the contrary in this Agreement, XL
                  Capital shall not request any Loan to be made to it, and no
                  Loan shall be made to XL Capital, until all of the Banks have
                  executed and delivered the Fourth Amendment to this Agreement
                  or have otherwise consented in writing to XL Capital becoming
                  a Borrower hereunder.

            SECTION 2. Addition of XL Capital as Borrower and Guarantor and of
XL Mid Ocean as Guarantor. Each of XL Mid Ocean and XL Capital hereby agrees to

amended hereby) and agrees to be bound by the terms of the Credit Agreement (as
so amended) as a Guarantor. XL Capital hereby agrees to become and be a Borrower

      the Agent with sufficient copies for each Bank a certificate with respect

      Agent with sufficient copies for each Bank (i) certified copies of the

      the opinions delivered by counsel to the Borrowers and the Guarantors on
      the Closing Date.

      by this Agreement shall be satisfactory to the Required Banks, and each
      Bank shall have received all such counterpart originals or certified or

<PAGE>

      by XL Capital for each Bank meeting the requirements of Section 2.03 of
      the Credit Agreement as hereby amended) and such other documents and
      proceedings in connection with such transactions, in form and substance
      satisfactory to it, as any Bank have reasonably requested.

said Commonwealth.

            SECTION 6. 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
all such counterparts shall constitute but one and the same instrument.

                  trust or other account and securing such liabilities;
                  provided, that in no case shall an Asset Accumulation Lien

                  shall not be an Asset Accumulation Lien.

                        "Total Adjusted Funded Debt" shall have the meaning
                  given that term in Section 6.06 hereof.

            (b) Section 5.01 of the Credit Agreement is hereby amended by adding
      at the end thereof a new paragraph (j) thereof to read as follows:

                              (j) Information Regarding Asset Accumulation

                  (i) Total Adjusted Funded Debt to (ii) the sum of Total
                  Adjusted Funded Debt plus Consolidated Net Worth to be greater
                  than 0.35 at any time. As used herein, the term "Total

                  such letters of credit) issued for the account of, or
                  guaranteed by, XL Capital or any of its consolidated
                  Subsidiaries at such time (irrespective of whether the

                                   ARTICLE II

                                   THE CREDITS

      2.01. Revolving Credit Loans.

      (a) Revolving Credit Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Bank,
severally and not jointly, agrees to make loans ("Loans") to a Borrower at any
time or from time to time on or after the date hereof and to but not including
the Expiration Date (it being understood that Loans may be outstanding to more
than one of the Borrowers at any time). A Bank shall have no obligation to make
any Loan if, after such Loan is made, such Bank's Total Exposure would exceed
such Bank's Committed Amount. Each Bank's "Committed Amount" at any time shall
be equal to the amount set forth as its "Initial Committed Amount" below its
name on the signature pages hereof, as such amount may have been reduced under
Section 2.02(c) hereof at such time, and subject to transfer to or from another
Bank as provided in Section 9.13 hereof.

      (b) Nature of Credit. Within the limits of time and amount set forth in
this Section 2.01, and subject to the provisions of this Agreement, the
Borrowers may borrow, repay and reborrow Loans hereunder.

      (c) Revolving Credit Notes. The obligation of the Borrowers to repay the
unpaid principal amount of the Loans made to it by each Bank and to pay interest
thereon shall be evidenced in part by promissory notes of the Borrowers, one to
each Bank, dated the Closing Date (the "Notes") in substantially the form
attached hereto as Exhibit A-1 (in the case of XL Insurance), Exhibit A-2 (in
the case of XL Mid Ocean) or Exhibit A-3 (in the case of XL Capital), with the
blanks appropriately filled, payable to the order of such Bank in a face amount
equal to such Bank's Initial Committed Amount.


                                      -8-
<PAGE>

      (d) Maturity. To the extent not due and payable earlier, the Loans shall
be due and payable on the Expiration Date.

      2.02. Facility Fee; Initial Fee, Reduction of the Committed Amounts.

      (a) Facility Fee. XL Capital agrees to pay to the Administrative Agent for
the account of each Bank a facility fee (the "Facility 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 seven basis points (0.07%), payable on such Bank's Committed Amount (whether
used or unused) in effect on such day. Such fee shall be payable quarterly on
the last day of each March, June, September and December after the Closing Date,
and on the Expiration Date, for the preceding period for which such fee has not
been paid.

      (b) Initial Fee. XL Capital agrees to pay on the Closing Date to the
Administrative Agent for the account of each Bank an initial fee equal to five
basis points (0.05%), payable on such Bank's Committed Amount on the Closing
Date.

      (c) Reduction of the Committed Amounts. XL Capital may at any time or from
time to time reduce Pro Rata the Committed Amounts of the Banks to an aggregate
amount (which may be zero) not less than the sum of the unpaid principal amount
of the Loans then outstanding plus the principal amount of all Loans not yet
made as to which notice has been given by the Borrower under Section 2.03
hereof. Any reduction of the Committed Amounts shall be in an aggregate minimum
amount of $20,000,000 and in an amount which is an integral multiple of
$10,000,000. Reduction of the Committed Amounts shall be made by providing not
less than three Business Days' notice (which notice shall be irrevocable) to
such effect to the Administrative Agent, which will promptly advise the Banks of
such notice. After the date specified in such notice the Facility Fee shall be
calculated upon the Committed Amounts as so reduced.

      2.03. Making of Loans. Whenever a Borrower desires that the Banks make
Loans, XL Capital shall provide Standard Notice to the Administrative Agent
setting forth the following information (a separate notice being required for
each such type of Loans):

      (a) Whether the proposed Loans are to be made to XL Insurance, to XL
Capital or to XL Mid Ocean;

      (b) The date, which shall be a Business Day, on which such proposed Loans
are to be made;

      (c) The aggregate principal amount of such proposed Loans, which shall be
the sum of the principal amounts selected pursuant to clause (d) of this Section
2.06, and which shall be an integral multiple of $1,000,000.00 not less than
$10,000,000.00;

      (d) The interest rate Option or Options selected in accordance with
Section 2.04(a) hereof and the principal amounts selected in accordance with
Section 2.04(d) hereof of the Alternate Base Rate Portion and each Funding
Segment of the Euro-Rate Portion of such proposed Loans; and

      (e) With respect to each such Funding Segment of such proposed Loans, the
Funding Period to apply to such Funding Segment, selected in accordance with
Section 2.04(c) hereof.

Standard Notice having been so provided, the Administrative Agent shall promptly
notify each Bank of the information contained therein and of the amount of such
Bank's Loan. Unless any applicable condition specified in Article IV hereof has
not been satisfied, on the date specified in such Standard Notice each Bank
shall make the proceeds of its Loan available to the Administrative Agent at the
Administrative Agent's Office, no later than 12:00 o'clock Noon, Pittsburgh
time, in funds immediately available at such Office. The Administrative Agent
will make the funds so received available to the applicable Borrower in funds
immediately available at the Administrative Agent's Office.

      2.04. Interest Rates.

      (a) Optional Bases of Borrowing. The unpaid principal amount of the Loans
shall bear interest for each day until due on one or more bases selected by the
Borrower from among the interest rate Options set forth below. Subject to the
provisions of this Agreement the applicable Borrower may select different
Options to apply simultaneously to different Portions of its Loans and may
select different Funding Segments to apply simultaneously to different parts of
the Euro-Rate Portion of such Loans. The aggregate number of Funding Segments
applicable to the Euro-Rate Portion of the Loans at any time shall not exceed
six.

            (i) Alternate Base Rate Option: The Alternate Base Rate Option is a
      rate per annum (the "Alternate Base Rate") (computed on the basis of a
      year of 365 or 366 days, as the case may be) for each day equal to the
      higher of: (A) the Base Rate for such day or (B) the Federal Funds
      Effective Rate for such day plus 0.50% per annum. "Base Rate" as used
      herein shall mean the interest rate per annum announced from time to time
      by the Administrative Agent as its prime rate. "Federal Funds Effective
      Rate" for any day shall mean the rate per annum (rounded upward to the
      nearest 1/100 of 1 %) determined by the Administrative Agent (which
      determination shall be conclusive) to be the rate per annum announced by
      the Federal Reserve Bank of New York (or any successor) on such day as
      being the weighted average of the rates on overnight Federal funds
      transactions arranged by Federal funds brokers on the previous trading
      day, as computed and announced by such Federal Reserve Bank (or any
      successor) in substantially the same manner as such Federal Reserve Bank
      computes and announces the weighted average it refers to as the "Federal
      Funds Effective Rate" as of the date of this Agreement; provided, that if
      such Federal Reserve Bank (or its successor) does not announce such rate
      on any day, the "Federal Funds Effective Rate" for such day shall be the
      Federal Funds Effective Rate for the last day on which such rate was
      announced. Changes in the Alternate Base Rate shall take effect on the
      date the Administrative Agent announces a change in the Base Rate or the
      Federal Reserve Bank announces a change in the Federal Funds Effective
      Rate, as the case may be;

            (ii) Euro-Rate Option: The Euro-Rate Option is a rate per annum
      (based on a year of 360 days and actual days elapsed) for each day equal
      to the Euro-Rate for such day plus the Applicable Margin for such day.
      "Euro-Rate" for any day, as used herein, shall mean for each Funding
      Segment of the Euro-Rate Portion corresponding to a proposed or existing
      Euro-Rate Funding Period the rate per annum determined by the
      Administrative Agent by dividing (the resulting quotient to be rounded
      upward to the nearest 1/100 of 1%) (A) the rate of interest (which shall
      be the same for each day in such Euro-Rate Funding Period) determined in
      good faith by the Administrative Agent in accordance with its usual
      procedures (which determination shall be conclusive) to be the average of
      the rates per annum for deposits in Dollars offered to major money center
      banks in the London interbank market at approximately 11:00 a.m., London
      time, two London Business Days prior to the first day of such Euro-Rate
      Funding Period for delivery on the first day of such Euro-Rate Funding
      Period in amounts comparable to such Funding Segment and having maturities
      comparable to such Funding Period by (B) a number equal to 1.00 minus the
      Euro-Rate Reserve Percentage.

            The "Euro-Rate" may also be expressed by the following formula:

                   [average of the rates offered to major money  ]
                   [center banks in the London interbank market  ]
      Euro-Rate =  [determined by the Administrative Agent per subsection (A)  ]
                   -------------------------------------------------------------
                   [1.00 - Euro-Rate Reserve Percentage          ]

            "Euro-Rate Reserve Percentage" for any day shall mean the percentage
      (expressed as a decimal, rounded upward to the nearest 1/100 of 1%), as
      determined in good faith by the Administrative Agent (which determination
      shall be conclusive), which is in effect on such day as


                                      -10-
<PAGE>

      prescribed by the Board of Governors of the Federal Reserve System (or any
      successor) representing the maximum reserve requirement (including,
      without limitation, supplemental, marginal and emergency reserve
      requirements) with respect to eurocurrency funding (currently referred to
      as "Eurocurrency liabilities") of a member bank in such System. The
      Euro-Rate shall be adjusted automatically as of the effective date of each
      change in the Euro-Rate Reserve Percentage. The Euro-Rate Option shall be
      calculated in accordance with the foregoing whether or not any Bank is
      actually required to hold reserves in connection with its eurocurrency
      funding or, if required to hold such reserves, is required to hold
      reserves at the "Euro-Rate Reserve Percentage" as herein defined.

            The Administrative Agent shall give prompt notice to the applicable
      Borrower and to the Banks of the Euro-Rate determined or adjusted in
      accordance with the definition of the Euro-Rate, which determination or
      adjustment shall be conclusive if made in good faith.

            (b) Applicable Margin. "Applicable Margin" shall mean 0.380% plus
      the Utilization Rate for such day. "Utilization Rate" shall mean (x)
      0.125% for any day on which the aggregate outstanding principal amount of
      all Loans under this Agreement exceeds 66% of the sum of the Committed
      Amounts of all Banks on such day, (y) 0.05% for any day on which the
      aggregate outstanding principal amount of all Loans under this Agreement
      exceeds 33%, but is less than or equal to 66%, of the sum of the Committed
      Amounts of all Banks on such day and (z) zero for each other day.

            (c) Funding Periods. At any time when a Borrower shall select,
convert to or renew the Euro-Rate Option to apply to any part of the Loans, such
Borrower shall specify one or more periods (the "Funding Periods") during which
each such Option shall apply, such Funding Periods being as set forth below:

Interest Rate Option                Available Funding Periods
- --------------------                -------------------------

   Euro-Rate Option                 One, two, three, six or twelve months or, if
                                    acceptable to all Banks, one or two weeks
                                    ("Euro-Rate Funding Period");

provided, that:

            (i) Each Euro-Rate Funding Period shall begin on a London Business
      Day, and the term "month", when used in connection with a Euro-Rate
      Funding Period, shall be construed in accordance with prevailing practices
      in the interbank eurodollar market at the commencement of such Euro-Rate
      Funding Period, as determined in good faith by the Administrative Agent
      (which determination shall be conclusive); and

            (ii) A Borrower may not select a Funding Period that would end after
      the Expiration Date.

      (d) Transactional Amounts. Every selection of, conversion from, conversion
to or renewal of an interest rate Option and every payment or prepayment of any
Loans shall be in a principal amount such that after giving effect thereto the
aggregate principal amount of the Alternate Base Rate Portion of the Loans, or
the aggregate principal amount of each Funding Segment of the Euro-Rate Portion
of the Loans, shall be as set forth below:

Portion or Funding Segment            Allowable Aggregate Principal Amounts
- --------------------------            -------------------------------------

Alternate Base Rate Portion and       $10,000,000 plus an integral
Each Funding Segment of the           multiple of $1,000,000.
Euro-Rate Portion


                                      -11-
<PAGE>

      (e) Euro-Rate Unascertainable; Impracticability. If

            (i) on any date on which a Euro-Rate would otherwise be set the
      Administrative Agent (in the case of clauses (A) or (B) below) or any Bank
      (in the case of clause (C) below) shall have determined in good faith
      (which determination shall be conclusive) that:

                  (A) adequate and reasonable means do not exist for
            ascertaining such Euro-Rate,

                  (B) a contingency has occurred which materially and adversely
            affects the interbank eurodollar market, or

                  (C) the effective cost to such Bank of funding a proposed
            Funding Segment of the Euro-Rate Portion from a Corresponding Source
            of Funds shall exceed the Euro-Rate applicable to such Funding
            Segment, or

            (ii) at any time any Bank shall have determined in good faith (which
      determination shall be conclusive) that the making, maintenance or funding
      of any part of the Euro-Rate Portion has been made impracticable or
      unlawful by compliance by such Bank or a Notional Euro-Rate Funding Office
      in good faith with any applicable Law or guideline or interpretation or
      administration thereof by any Official Body charged with the
      interpretation or administration thereof or with any applicable request or
      directive of any such Official Body (whether or not having the force of
      law);

then, and in any such event, the Administrative Agent or such Bank, as the case
may be, may notify the Borrowers of such determination (and any Bank giving such
notice shall notify the Administrative Agent, which shall advise the other Banks
of such notice). Upon such date as shall be specified in such notice (which
shall not be earlier than the date such notice is given), the obligation of each
of the Banks to allow the Borrowers to select, convert to or renew the Euro-Rate
Option shall be suspended until the Administrative Agent or such Bank, as the
case may be, shall have later notified the Borrowers (and any Bank giving such
notice shall notify the Administrative Agent) of the Administrative Agent's or
such Bank's determination in good faith (which determination shall be
conclusive) that the circumstance giving rise to such previous determination no
longer exist.

      If any Bank notifies the Borrowers of a determination under subsection
(ii) of this Section 2.04(e), the Euro-Rate Portion of the Loans of such Bank
(the "Affected Bank") shall automatically be converted to the Alternate Base
Rate Option as of the date specified in such notice (and accrued interest
thereon shall be due and payable on such date).

      If at the time the Administrative Agent or a Bank makes a determination
under subsection (i) or (ii) of this Section 2.04(e) and XL Capital previously
has notified the Administrative Agent that a Borrower wishes to select, convert
to or renew the Euro-Rate Option with respect to any proposed Loans but such
Loans have not yet been made, such notification shall be deemed to provide for
selection of, conversion to or renewal of the Alternate Base Rate Option instead
of the Euro-Rate Option, with respect to such Loans or, in the case of a
determination by a Bank, such Loans of such Bank.

      2.05. Conversion or Renewal of Interest Rate Options.

      (a) Conversion or Renewal. Subject to the provisions of Section 2.10(b)
hereof, and if no Event of Default or Potential Default shall have occurred and
be continuing or shall exist, a Borrower may convert any part of its Loans from
any interest rate Option or Options to one or more different interest rate
Options and may renew the Euro-Rate Option as to any Funding Segment of the
Euro-Rate Portion:

            (i) At any time with respect to conversion from the Alternate Base
      Rate Option; or


                                      -12-
<PAGE>

            (ii) At the expiration of any Funding Period with respect to
      conversions from or renewals of the Euro-Rate Option as to the Funding
      Segment corresponding to such expiring Funding Period.

Whenever a Borrower desires to convert or renew any interest rate Option or
Options, XL Capital shall provide to the Administrative Agent Standard Notice
setting forth the following information (and the Agent shall promptly advise the
Banks of such information):

            (w) The date, which shall be a Business Day, on which the proposed
      conversion or renewal is to be made;

            (x) The principal amounts selected in accordance with Section
      2.04(d) hereof of the Alternate Base Rate Portion and each Funding Segment
      of the Euro-Rate Portion to be converted from or renewed;

            (y) The interest rate Option or Options selected in accordance with
      Section 2.04(a) hereof and the principal amounts selected in accordance
      with Section 2.04(d) hereof of the Alternate Base Rate Portion and each
      Funding Segment of the Euro-Rate Portion to be converted to; and

            (z) With respect to each Funding Segment to be converted to or
      renewed, the Funding Period selected in accordance with Section 2.04(c)
      hereof to apply to such Funding Segment.

Standard Notice having been so provided, after the date specified in such
Standard Notice, interest shall be calculated upon the principal amount of the
Loans as so converted or renewed. Interest on the principal amount of any part
of the Loans converted or renewed (automatically or otherwise) shall be due and
payable on the conversion or renewal date.

      (b) Failure to Convert or Renew. Absent due notice from XL Capital of
conversion or renewal in the circumstances described in Section 2.05(a)(ii)
hereof, any part of the Euro-Rate Portion for which such notice is not received
shall be converted automatically to the Alternate Base Rate Option on the last
day of the expiring Funding Period.

      2.06. Prepayments Generally. Whenever a Borrower desires or is required to
prepay any part of its Loans, XL Capital shall provide Standard Notice to the
Administrative Agent setting forth the following information (and the Agent
shall promptly advise the Banks of such information):

      (a) Whether such prepayment is to be applied to the Loans outstanding to
XL Insurance, XL Capital or XL Mid Ocean;

      (b) The date, which shall be a Business Day, on which the proposed
prepayment is to be made;

      (c) The total principal amount of such prepayment, which shall be the sum
of the principal amounts selected pursuant to clause (d) of this Section 2.06;
and

      (d) The principal amounts selected in accordance with Section 2.04(d)
hereof of the Alternate Base Rate Portion and each part of each Funding Segment
of the Euro-Rate Portion to be prepaid.

Standard Notice having been so provided, on the date specified in such Standard
Notice, the principal amounts of the Alternate Base Rate Portion and each part
of the Euro-Rate Portion specified in such notice, together with interest on
each such principal amount to such date, shall be due and payable.

      2.07. Optional Prepayments. Each Borrower shall have the right at its
option from time to time to prepay its Loans in whole or part without premium or
penalty (subject, however, to Section 2.10(b) hereof):


                                      -13-
<PAGE>

      (a) At any time with respect to any part of the Alternate Base Rate
Portion, provided, however, that such prepayment shall be in a principal amount
of $10,000,000 or an integral multiple of $1,000,000 in excess thereof; or

      (b) At the expiration of any Funding Period with respect to prepayment of
the Euro-Rate Portion with respect to any part of the Funding Segment
corresponding to such expiring Funding Period, provided, however, that such
prepayment shall be in a principal amount of $10,000,000 or an integral multiple
of $1,000,000 in excess thereof.

Any such prepayment shall be made in accordance with Section 2.06 hereof.

      2.08. Interest Payment Dates. Interest on the Alternate Base Rate Portion
shall be due and payable on each Regular Payment Date. Interest on each Funding
Segment of the Euro-Rate Portion shall be due and payable on the last day of the
corresponding Euro-Rate Funding Period and, if such Euro-Rate Funding Period is
longer than three months, also every third month during such Funding Period.
After maturity of any part of the Loans (by acceleration or otherwise), interest
on such part of the Loans shall be due and payable on demand.

      2.09. Pro Rata Treatment; Payments Generally; Interest on Overdue Amounts.

      (a) Pro Rata Treatment. Each borrowing and conversion and renewal of
interest rate Options hereunder shall be made, and all payments made in respect
of principal, interest, and Facility Fees due from the Borrowers hereunder or
under the Notes shall be applied, Pro Rata from and to each Bank, except for
payments of interest involving an Affected Bank as provided in Section 2.04(e)
hereof and payments to a Bank subject to a withholding deduction under Section
2.11(c) hereof. The failure of any Bank to make a Loan shall not relieve any
other Bank of its obligation to lend hereunder, but neither either Agent nor any
Bank shall be responsible for the failure of any other Bank to make a Loan.

      (b) Payments Generally. All payments and prepayments to be made by a
Borrower in respect of principal, interest, fees, indemnity, expenses or other
amounts due from such Borrower hereunder or under any Loan 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 to a Bank subject to a withholding deduction under
Section 2.11(c) hereof. Except for payments under Sections 2.10 and 9.04 hereof,
such payments shall be made to the Administrative Agent at its Office in Dollars
in funds immediately available at such Office, and payments under Sections 2.10
and 9.04 hereof shall be made to the applicable Bank at such domestic account as
it shall specify to the Borrowers from time to time in funds immediately
available at such account. Any payment or prepayment received by the
Administrative 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 Administrative Agent shall distribute to the Banks all such payments
received by it from a Borrower as promptly as practicable after receipt by the
Administrative Agent.

      (c) Interest on Overdue Amounts. To the extent permitted by law, after
there shall have become due (by acceleration or otherwise) principal, interest,
fees, indemnity, expenses or any other amounts due from the Borrowers hereunder
or under any other Loan 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 the following:

            (i) In the case of any part of the Euro-Rate Portion of any Loans,
      (A) until the end of the applicable then-current Funding Period at a rate
      per annum 2% above the rate otherwise applicable to such part, and (B)
      thereafter in accordance with the following clause (ii); and


                                      -14-
<PAGE>

            (ii) In the case of any other amount due from a Borrower hereunder
      or under any Loan Document, 2% above the then-current Alternate Base Rate
      Option applicable to Loans.

To the extent permitted by law, interest accrued on any amount which has become
due hereunder or under any Loan Document shall compound on a day-by-day basis,
and hence shall be added daily to the overdue amount to which such interest
relates.

      2.10. Additional Compensation in Certain Circumstances.

      (a) Increased Costs or Reduced Return Resulting From Taxes, Reserves,
Capital Adequacy Requirements, Expenses, Etc. 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 or any Notional Euro-Rate Funding Office to
      any tax or changes the basis of taxation with respect to this Agreement,
      the Notes, the Loans or payments by the Borrowers of principal, interest,
      facility fee or other amounts due from the Borrowers hereunder or under
      the Notes (except for taxes on the overall net income or overall gross
      receipts of such Bank or such Notional Euro-Rate Funding Office imposed by
      the jurisdictions (federal, state and local) in which the Bank's principal
      office or Notional Euro-Rate Funding 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 or any Notional
      Euro-Rate Funding Office (other than requirements expressly included
      herein in the determination of the Euro-Rate hereunder),

            (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 any
      Notional Euro-Rate Funding Office, or (B) otherwise applicable to the
      obligations of any Bank or any Notional Euro-Rate Funding Office under
      this Agreement, or

            (iv) imposes upon any Bank or any Notional Euro-Rate Funding Office
      any other condition or expense with respect to this Agreement, the Notes
      or its making, maintenance or funding of any Loan,

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, any Notional Euro-Rate Funding Office or, in the case of clause (iii)
hereof, any Person controlling a Bank, with respect to this Agreement, the Notes
or the making, maintenance or funding of any Loan (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 being deemed for this purpose to have made, maintained or funded each
Funding Segment of the Euro-Rate Portion from a Corresponding Source of Funds),
such Bank may from time to time notify the Borrowers 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 or
such Notional Euro-Rate Funding Office for such increase, reduction or
imposition. Such amount shall be due and payable by any applicable Borrower 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 Alternate Base Rate Option applicable to
Loans. A certificate by such Bank as to the amount due and payable under this
Section 2.10(a) from time to time and the method of calculating such amount
shall be conclusive. Each Bank agrees that it will use good faith


                                      -15-
<PAGE>

efforts to notify the Borrowers of the occurrence of any event that would give
rise to a payment under this Section 2.10(a); 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 Borrowers' obligations hereunder.

      (b) Funding Breakage. In addition to all other amounts payable hereunder,
if and to the extent for any reason any part of any Funding Segment of any
Euro-Rate Portion of the Loans becomes due (by acceleration or otherwise), or is
paid, prepaid or converted to another interest rate Option (whether or not such
payment, prepayment or conversion is mandatory or automatic and whether or not
such payment or prepayment is then due), on a day other than the last day of the
corresponding Funding Period (the date such amount so becomes due, or is so
paid, prepaid or converted, being referred to as the "Funding Breakage Date"),
the applicable Borrower shall pay each Bank an amount ("Funding Breakage
Indemnity") determined by such Bank as follows:

            (i) first, calculate the following amount: (A) the principal amount
      of such Funding Segment of the Loans owing to such Bank which so became
      due, or which was so paid, prepaid or converted, times (B) the greater of
      (x) zero or (y) the rate of interest applicable to such principal amount
      on the Funding Breakage Date minus the Treasury Rate as of the Funding
      Breakage Date, times (C) the number of days from and including the Funding
      Breakage Date to but not including the last day of such Funding Period,
      times (D) 1/360;

            (ii) the Funding Breakage Indemnity to be paid by such Borrower to
      such Bank shall be the amount equal to the present value as of the Funding
      Breakage Date (discounted at the Treasury Rate as of such Funding Breakage
      Date, and calculated on the basis of a year of 365 or 366 days, as the
      case may be, and actual days elapsed) of the amount described in the
      preceding clause (i) (which amount described in the preceding clause (i)
      is assumed for purposes of such present value calculation to be payable on
      the last day of the corresponding Funding Period).

Such Funding Breakage Indemnity shall be due and payable on demand, and each
Bank shall, upon making such demand, notify the Administrative Agent of the
amount so demanded. In addition, such Borrower shall, on the due date for
payment of any Funding Breakage Indemnity, pay to such Bank an additional amount
equal to interest on such Funding Breakage Indemnity from the Funding Breakage
Date to but not including such due date at the Alternate Base Rate Option
applicable to Loans (calculated on the basis of a year of 360 days and actual
days elapsed). The amount payable to each Bank under this Section 2.10(b) shall
be determined in good faith by such Bank, and such determination shall be
conclusive.

      2.11. Taxes.

      (a) Payments Net of Taxes. All payments made by the Borrowers under this
Agreement or any other Loan 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 each Agent and each Bank, income or franchise
      taxes imposed on such Agent or such Bank by the jurisdiction under the
      laws of which such 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 or Agent 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 make or book
      Loans are located or any political subdivision or taxing authority thereof
      or therein


                                      -16-
<PAGE>

(all such non-excluded taxes, levies, imposts, deductions, charges or
withholdings being hereinafter called "Taxes"), unless the Borrower is required
to withhold or deduct Taxes. If any Taxes are required to be withheld or
deducted from any amounts payable to either Agent or any Bank under this
Agreement or any other Loan Document, the applicable Borrower shall pay the
relevant amount of such Taxes and the amounts so payable to such Agent or such
Bank shall be increased to the extent necessary to yield to such 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 Loan Documents. Whenever any Taxes are paid by a Borrower with respect to
payments made in connection with this Agreement or any other Loan Document, as
promptly as possible thereafter, such Borrower shall send to the Administrative
Agent for its own account or for the account of the other Agent or such Bank, as
the case may be, a certified copy of an original official receipt received by
such Borrower showing payment thereof. If a Bank or either Agent 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 a Borrower, or with respect to
which a Borrower has paid additional amounts pursuant to this Section 2.11, such
Bank or Agent shall promptly after the date of such receipt pay over the amount
of such refund to such Borrower (but only to the extent of indemnity payments
made, or additional amounts paid, by a Borrower under this Section 2.11 with
respect to Taxes giving rise to such refund and only to the extent that such
Bank or Agent has determined that the amount of any such refund is directly
attributable to payments made under this Agreement), net of all reasonable
expenses of such Bank or Agent (including additional Taxes attributable to such
refund, as determined by such Bank or Agent) and without interest (other than
interest, if any, paid by the relevant Official Body with respect to such
refund). A Borrower receiving any such payment from a Bank or Agent shall, upon
demand, pay to such Bank or Agent any amount paid over to such Borrower by such
Bank or Agent (plus penalties, interest or other charges) in the event such Bank
or Agent is required to repay any portion of such refund to such Official Body.
Nothing in this Section 2.11(a) shall entitle a Borrower to have access to the
records of any Bank or Agent, including, without limitation, tax returns.

      (b) Indemnity. Each Borrower hereby indemnifies each Agent and each of the
Banks for the full amount of all Taxes attributable to payments by or on behalf
of such Borrower hereunder or under any of the other Loan Documents, any Taxes
paid by such 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 such Agent or such Bank as a result of any
failure to pay such Taxes, except by reason of unreasonable delay by such Agent
or Bank in notifying the Borrower or in making payment after payment was
received from the Borrower), whether or not such Taxes were correctly or legally
asserted. Such indemnification shall be made within 30 days from the date such
Bank or such Agent, as the case may be, makes written demand therefor.

      (c) Withholding and Backup Withholding. Each Bank or Agent 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 any
payment is due to be made to it hereunder or under any other Loan Document, it
will furnish to the Borrowers and the Administrative 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 or Agent is entitled to receive payments under this
      Agreement and the other Loan 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 Borrowers and the Administrative Agent a Form
1001 or 4224 and Form W-8 or W-9, or successor applicable forms, agrees to
deliver to the Borrowers and the Administrative


                                      -17-
<PAGE>

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 Borrowers and the Administrative
Agent, certifying in the case of a Form 1001 or Form 4224 that such Bank or
Agent is entitled to receive payments under this Agreement or any other Loan
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 or Agent advises the Borrowers and the Administrative 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.

      2.12. Funding by Branch, Subsidiary or Affiliate.

      (a) Notional Funding. Each Bank shall have the right from time to time,
prospectively or retrospectively, without notice to the Borrowers, to deem any
branch, subsidiary or affiliate of such Bank to have made, maintained or funded
any part of the Euro-Rate Portion at any time. Any branch, subsidiary or
affiliate so deemed shall be known as a "Notional Euro-Rate Funding Office."
Such Bank shall deem any part of the Euro-Rate Portion of the Loans or the
funding therefor to have been transferred to a different Notional Euro-Rate
Funding Office if such transfer would avoid or cure an event or condition
described in Section 2.04(e)(ii) hereof or would lessen compensation payable by
a Borrower under Section 2.10(a) hereof, and if such Bank determines in its sole
discretion that such transfer would be practicable and would not have a material
adverse effect on such part of the Loans, such Bank or any Notional Euro-Rate
Funding Office (it being assumed for purposes of such determination that each
part of the Euro-Rate Portion is actually made or maintained by or funded
through the corresponding Notional Euro-Rate Funding Office). Notional Euro-Rate
Funding Offices may be selected by such Bank without regard to such Bank's
actual methods of making, maintaining or funding Loans or any sources of funding
actually used by or available to such Bank.

      (b) Actual Funding. Each Bank shall have the right from time to time to
make or maintain any part of the Euro-Rate Portion by arranging for a branch,
subsidiary or affiliate of such Bank to make or maintain such part of the
Euro-Rate Portion. Such Bank shall have the right to (i) hold any applicable
Note payable to its order for the benefit and account of such branch, subsidiary
or affiliate or (ii) request the applicable Borrower to issue one or more
promissory notes in the principal amount of such Euro-Rate Portion, in
substantially the form attached hereto as Exhibit A-1, A-2 or A-3, as the case
may be, with the blanks appropriately filled, payable to such branch, subsidiary
or affiliate and with appropriate changes reflecting that the holder thereof is
not obligated to make any additional Loans to such Borrower. Each Borrower
agrees to comply promptly with any request under subsection (ii) of this Section
2.12(b). If any Bank causes a branch, subsidiary or affiliate to make or
maintain any part of the Euro-Rate Portion hereunder, all terms and conditions
of this Agreement shall, except where the context clearly requires otherwise, be
applicable to such part of the Euro-Rate Portion and to any note payable to the
order of such branch, subsidiary or affiliate to the same extent as if such part
of the Euro-Rate Portion were made or maintained and such note were a Note
payable to such Bank's order.

      2.13. Extensions of Expiration Date. The Borrowers may, at their option,
give the Administrative Agent written notice (an "Extension Request") not more
than 90 days, nor less than 60 days, prior to the then effective Expiration
Date, of the Borrowers' desire to extend the then effective Expiration Date to a
date which is not later than 364 days after the "Reset Date". The "Reset Date"
means the date which is 30 days prior to the then effective Expiration Date. The
Administrative Agent shall promptly inform the Banks of such Extension Request.
Each Bank that agrees with such Extension Request shall deliver to the
Administrative Agent its express written consent thereto no later than the Reset
Date. No extension shall


                                      -18-
<PAGE>

become effective unless agreed to by the Required Banks on or prior to the Reset
Date. If all Banks have not in writing expressly consented to any such Extension
Request by the Reset Date, then the Administrative Agent shall so notify the
Borrowers and the Borrowers, at their option, may, as of the then effective
Expiration Date, (i) replace any Bank which has not agreed to such Extension
Request (a "Nonextending Bank") with another commercial lending institution
reasonably satisfactory to the Administrative Agent (a "Replacement Bank") by
giving notice of the name of such Replacement Bank to the Administrative Agent
not later than five Business Days prior to the then effective Expiration Date or
(ii) pay the Loans of such Nonextending Bank. Upon notice from the
Administrative Agent, such Nonextending Bank shall, as of the then effective
Expiration Date, assign all of its interests hereunder to such Replacement Bank
in accordance with the provisions of Section 9.13 hereof. If the Required Banks
shall have consented to such Extension Request, then, on the then effective
Expiration Date, after payment by the Borrower (or, if applicable, by a
Replacement Bank) of all amounts payable hereunder to each Nonextending Bank,
the Expiration Date shall be deemed to have been extended to, and shall be, the
date specified in such Extension Notice. The Administrative Agent shall promptly
after any such extension advise the Banks of any decrease in the aggregate
Committed Amounts of the Banks and of the respective Committed Amounts of all
Banks. Each Bank may agree or not agree to any such Extension Request in its
sole and absolute discretion and any Bank not agreeing (or not responding) to an
Extension Request shall not be deemed to have extended the Expiration Date
regardless of whether a Replacement Bank is obtained.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES.

Each Borrower represents and warrants that:

      3.01. Organization and Qualification. Such Borrower 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 Borrower and each of its Subsidiaries has the power and authority to own
its properties and assets, and to carry on its business as currently 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 Borrower's Subsidiaries setting forth their respective
jurisdictions of incorporation is set forth in Schedule 3.01 hereto. Such
Borrower 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 the Administrative
Agent.

      3.02. Corporate Power and Authorization. Such Borrower has corporate power
and authority to, make and carry out this Agreement and any other Loan Document
to which it is a party to make the borrowings provided for herein, to execute
and deliver this Agreement and, in the case of such Borrower, the applicable
Notes and to perform its obligations hereunder and under any such Loan Documents
and all such action has been duly authorized by all necessary corporate
proceedings on its part.

      3.03. Financial Information. Such Borrower has furnished to the
Administrative Agent with sufficient copies for each Bank copies of the audited
consolidated financial statements of such Borrower and its consolidated
Subsidiaries including a consolidated balance sheet and related statements of
income and retained earnings for the fiscal year ending November 30, 1998. Such
financial statements fairly present the financial position of such Borrower and
its consolidated Subsidiaries as of the date of such reports and the
consolidated results of their operations and cash flows for the fiscal period
then


                                      -19-
<PAGE>

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 Banks in writing prior to the
Closing Date (including by disclosure in the financial statements delivered to
the Banks referred to in Section 3.03 hereof), there is no litigation or
governmental proceeding by or against such Borrower 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 Borrower and after
taking into account the nature of such Borrower's business and activities) to
have a Material Adverse Effect if adversely determined.

      3.05. No Adverse Changes. Since November 30, 1998, 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 Borrower or of any applicable Law or of any
material agreement or instrument to which such Borrower 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 Borrower pursuant to the terms of any such agreement
or instrument.

      (b) No authorization, consent, approval, license, exemption or other
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 Borrower. This Agreement constitutes, and
the applicable Notes when duly executed and delivered by such Borrower pursuant
to the provisions hereof will constitute, legal, valid and binding obligations
of such Borrower 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 Borrower have
been properly prepared, executed and filed. All taxes, assessments, fees and
other governmental charges upon such Borrower or upon its properties, income or
sales which are due and payable have been paid. The reserves and provisions for
taxes, if any, on the books of such Borrower are adequate for all open years and
for its current fiscal period as determined in accordance with GAAP.

      3.09. Use of Proceeds. Such Borrower will use the proceeds from any
borrowing hereunder for general corporate purposes (which may include
acquisitions and may include refinancing of other indebtedness). Such 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. Such 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 Borrower and each Subsidiary of
such Borrower 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


                                      -20-
<PAGE>

and to carry on their respective businesses as currently conducted and currently
planned to be conducted without, to the best knowledge of such Borrower,
conflict with the rights of others.

      3.11. Accurate and Complete Disclosure. All information provided by or on
behalf of any Borrower to either Agent or any Bank 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 such Agent or such Bank,
as the case may be) 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 the Borrowers, 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 Borrower and each Affiliate of such
Borrower 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 Borrower and each of its Subsidiaries is
and has been in full compliance with all applicable Environmental Laws. Such
Borrower and each of its Subsidiaries have all approvals by Official Bodies
charged with the enforcement of Environmental Laws that are necessary or
desirable for the ownership and operation of their respective properties,
facilities and businesses as presently owned and operated and as currently
proposed to be owned and operated.

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

      3.15. Year 2000 Compliance. XL Capital has (i) initiated a review and
assessment of all areas within its and each of its Subsidiaries' business and
operations (including those affected by material suppliers, vendors and
customers) that could be adversely affected by the risk that computer
applications used by XL Capital or any of its Subsidiaries (or material
suppliers, vendors and customers other than risks affecting customers that may
give rise to claims under insurance policies issued by XL Capital or any
Subsidiary of XL Capital) may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999 (the "Year 2000 Problem") and (ii) developed a plan and
timetable for addressing the Year 2000 Problem on a timely basis. Based on the
foregoing, XL Capital believes that all computer applications of XL Capital and
its Subsidiaries that are material to its or any of its Subsidiaries' business
and operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1, 2000
("Year 2000 Compliant"), except to the extent that a failure to do so could not
reasonably be expected to have a Material Adverse Effect.

notice of each material change in any Borrower's investment policy, underwriting
policy or other business policy.

      (i) Year 2000 Compliance. Promptly after any Borrower's discovery or

to the extent that such failure could not reasonably be expected to have a
Material Adverse Effect.

      5.02. Preservation of Existence and Franchises. Each Borrower shall, and
shall cause each of its Subsidiaries to, maintain its corporate existence,
rights and franchises in full force and effect in its jurisdiction of
incorporation. Each Borrower shall, and shall cause each of its Subsidiaries to,

improvements thereto so that the business carried on in connection therewith may
be properly conducted at all times, provided, however, that the foregoing shall
not impose on such Borrower or any Subsidiary of such Borrower any obligation in

mechanics, carriers, warehousemen, landlords and other like Persons which, if
unpaid, might result in the creation of a Lien upon any such property; and

      (c) on or prior to the date when due, all other lawful claims which, if
unpaid, might result in the creation of a Lien upon any such property (other
than Liens not forbidden by Section 6.03 hereof) or which, if unpaid, might give
rise to a claim entitled to priority over general creditors of such Borrower in
any proceeding under the Bermuda Companies Law or Bermuda Insurance Law, or any
insolvency proceeding, liquidation, receivership, rehabilitation, dissolution or
winding-up involving such Borrower or such Subsidiary;

provided that, unless and until foreclosure, distraint, levy, sale or similar
proceedings shall have been commenced, such Borrower need not pay or discharge
any such tax, assessment, charge, levy or claim so long as the validity thereof
is contested in good faith and by appropriate proceedings diligently conducted
and so long as such reserves or other appropriate provisions as may be required
by GAAP and SAP shall have been made therefor and so long as such failure to pay
or discharge does not have a Material Adverse Effect.

      5.06. Financial Accounting Practices. Such Borrower shall, and shall cause
each of its Subsidiaries to, make and keep books, records and accounts which, in
reasonable detail, accurately and fairly reflect its transactions and
dispositions of its assets and maintain a system of internal accounting controls
sufficient to provide reasonable assurances that transactions are recorded as
necessary to permit preparation of financial statements required under Section
5.01 hereof in conformity with GAAP and SAP, as applicable, and to maintain
accountability for assets.

      5.07. Compliance with Applicable Laws. Each Borrower shall, and shall
cause each of its Subsidiaries to, comply with all applicable Laws (including
but not limited to the Bermuda Companies Law and Bermuda Insurance Laws) in all
respects; provided that such Borrower or any Subsidiary of such Borrower shall
not be deemed to be in violation of this Section 5.07 as a result of any failure
to comply with any such Law which would not (i) result in fines, penalties,
injunctive relief or other civil or criminal liabilities which, in the
aggregate, would have a Materially Adversely Effect or (ii) otherwise impair the
ability of such Borrower to perform its obligations under this Agreement or the
Notes issued by it.

      5.08. Use of Proceeds. Each Borrower shall use the proceeds of all Loans
hereunder for its general corporate purposes (which may include funding
acquisitions and paying dividends).

continued undischarged or unstayed for a period of sixty days; or a decree or
order of a court having jurisdiction in the premises for the appointment of a
receiver or liquidator or trustee or assignee in bankruptcy or insolvency of
such Borrower or a substantial part of its property, or for the winding up or

shall have remained in force undischarged and unstayed for a period of sixty
days; or

      (l) Any Borrower shall institute proceedings to be adjudicated a voluntary

shall thereupon become and be immediately due and payable, without presentment,
demand, protest or notice or any kind, all of which are hereby expressly waived;
and (ii) as to any Event of Default specified under subsections (k) or (l) of
this Article VII, the Banks shall be under no further obligation to make Loans
hereunder and the unpaid balance of all Loans outstanding hereunder and interest

                                  ARTICLE VIII

                                   THE AGENTS

      8.01. Appointment. Each Bank hereby appoints Mellon Bank, N.A. to act as
Administrative Agent for such Bank under this Agreement and the other Loan
Documents and appoints The Chase Manhattan Bank to act as Syndication Agent for
such Bank under this Agreement and the other Loan Documents. Each Bank hereby
irrevocably authorizes each Agent to take such action on behalf of such Bank
under the provisions of this Agreement and the other Loan Documents, and to
exercise such powers and to perform such duties, as are expressly delegated to
or required of such Agent by the terms hereof or thereof, together with such
powers as are reasonably incidental thereto. Mellon Bank, N.A. hereby agrees to
act as Administrative Agent and The Chase Manhattan Bank agrees to act as
Syndication Agent, in each case on behalf of the Banks on the terms and
conditions set forth in this Agreement and the other Loan Documents, subject to
its right to resign as provided in Section 8.10 hereof. Each Bank hereby
irrevocably authorizes each Agent to execute and deliver each of the Loan
Documents and to accept delivery of such of the other Loan Documents as may not
require execution by such Agent. Each Bank agrees that the rights and remedies
granted to an Agent under the Loan Documents shall be exercised exclusively by
such Agent, and that no Bank shall have any right individually to exercise any
such right or remedy, except to the extent expressly provided herein or therein.

      8.02. General Nature of Each Agent's Duties. Notwithstanding anything to
the contrary elsewhere in this Agreement or in any other Loan Document:

            (a) Neither Agent shall have any duties or responsibilities except
      those expressly set forth in this Agreement and the other Loan Documents,
      and no implied duties or responsibilities on the part of either Agent
      shall be read into this Agreement or any Loan Document or shall otherwise
      exist.

            (b) The duties and responsibilities of each Agent under this
      Agreement and the other Loan Documents shall be mechanical and
      administrative in nature, and neither Agent shall have a fiduciary
      relationship in respect of any Bank.

            (c) Each Agent is and shall be solely the agent of the Banks.
      Neither Agent assumes, 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 Loan Documents).

            (d) Neither Agent shall be under any obligation to take any action
      hereunder or under any other Loan Document if such Agent believes in good
      faith that taking such action may conflict with any Law or any provision
      of this Agreement or any other Loan Document, or may require such Agent to
      qualify to do business in any jurisdiction where it is not then so
      qualified.


                                      -30-
<PAGE>

      8.03. Exercise of Powers. Each Agent shall take any action of the type
specified in this Agreement or any other Loan Document as being within such
Agent's rights, powers or discretion in accordance with directions from the
Required Banks (or, to the extent this Agreement or such Loan 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, each 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 Loan Document
expressly requires the direction or consent of the Required Banks (or some other
Person or set of Persons), in which case such 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. Neither
Agent shall have any liability to any Person as a result of (x) either Agent
acting or refraining from acting in accordance with the directions of the
Required Banks (or other applicable Person or set of Persons), (y) either 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 such Agent
has discretionary power to take such action, or (z) either Agent taking
discretionary action it is authorized to take under this Section (subject, in
the case of this clause (z), to the provisions of Section 8.04(a) hereof).

      8.04. General Exculpatory Provisions. Notwithstanding anything to the
contrary elsewhere in this Agreement or any other Loan Document:

      (a) Neither Agent shall be liable for any action taken or omitted to be
taken by it under or in connection with this Agreement or any other Loan
Document, unless caused by its own gross negligence or willful misconduct.

      (b) Neither Agent shall be responsible for (i) the execution, delivery,
effectiveness, enforceability, genuineness, validity or adequacy of this
Agreement or any other Loan Document, (ii) any recital, representation,
warranty, document, certificate, report or statement in, provided for in, or
received under or in connection with, this Agreement or any other Loan Document,
(iii) any failure of any Loan Party or Bank to perform any of their respective
obligations under this Agreement or any other Loan 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 Loan Documents or otherwise
from time to time.

      (c) Neither Agent shall 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 Loan Document on the part of
any Borrower, (ii) the business, operations, condition (financial or otherwise)
or prospects of any Borrower 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) Neither Agent shall not be under any obligation, either initially or
on a continuing basis, to provide 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 or any other Loan Document to be furnished by such Agent to such
Bank.

      8.05. Administration by the Agents.

      (a) Each 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 Loan Document) purportedly made by or on
behalf of the proper party or parties, and neither Agent shall have any duty to
verify the identity or authority of any Person giving such notice or other
communication.

      (b) Each Agent may consult with legal counsel (including, without
limitation, in-house counsel for such Agent or in-house or other counsel for any
Borrower), independent public accountants and any other


                                      -31-
<PAGE>

experts selected by it from time to time, and neither Agent shall 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) Each Agent may conclusively rely upon the truth of the statements and
the correctness of the opinions expressed in any certificates or opinions
furnished to either Agent in accordance with the requirements of this Agreement
or any other Loan Document. Whenever either Agent shall deem it necessary or
desirable that a matter be proved or established with respect to any Borrower or
Bank, such matter may be established by a certificate of such Borrower or Bank,
as the case may be, and each Agent may conclusively rely upon such certificate
(unless other evidence with respect to such matter is specifically prescribed in
this Agreement or another Loan Document).

      (d) Each 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 such Agent by reason of taking or continuing to
take any such action.

      (e) Each Agent may perform any of its duties under this Agreement or any
other Loan Document by or through agents or attorneys-in-fact. Neither Agent
shall be responsible for the negligence or misconduct of any agents or
attorneys-in fact selected by it with reasonable care.

      (f) Neither Agent shall be deemed to have any knowledge or notice of the
occurrence of any Event of Default or Potential Default unless such Agent has
received notice from a Bank or any Borrower referring to this Agreement,
describing such Event of Default or Potential Default, and stating that such
notice is a "notice of default". If an Agent receives such a notice, such Agent
shall give prompt notice thereof to the other Agent and each Bank.

      8.06. Bank Not Relying on Agent or Other Banks. Each Bank acknowledges as
follows: (a) Neither either Agent nor any other Bank has made any
representations or warranties to it, and no act taken hereafter by either Agent
or any other Bank shall be deemed to constitute any representation or warranty
by such Agent or such other Bank to it. (b) It has, independently and without
reliance upon either 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 Loan Documents. (c) It
will, independently and without reliance upon either 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 Loan Documents.

      8.07. Indemnification. Each Bank agrees to reimburse and indemnify each
Agent and its directors, officers, employees and agents (to the extent not
reimbursed by a Borrower and without limitation of the obligations of the
Borrowers 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 fees and disbursements of counsel for such Agent or such
other Person in connection with any investigative, administrative or judicial
proceeding commenced or threatened, whether or not such Agent or such other
Person shall be designated a party thereto) that may at any time be imposed on,
incurred by or asserted against such 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 Loan 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 Loan, 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 to the
extent resulting from the gross negligence or willful misconduct of such 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 Federal Funds Effective Rate.


                                      -32-
<PAGE>

      8.08. Each Agent in its Individual Capacity. With respect to its
Commitments and the Obligations owing to it, each Agent shall have the same
rights and powers under this Agreement and each other Loan Document as any other
Bank and may exercise the same as though it were not an Agent, and the terms
"Banks," "holders of Notes" and like terms shall include each Agent in its
individual capacity as such. Each 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, and engage in any other
business with, any Borrower and any stockholder, subsidiary or affiliate of any
Borrower, as though such Agent were not an Agent hereunder.

      8.09. Holders of Notes. The Administrative Agent may deem and treat the
Bank which is payee of a Note as the owner and holder of such Note for all
purposes hereof unless and until a Transfer Supplement with respect to the
assignment or transfer thereof shall have been filed with the Administrative
Agent in accordance with Section 9.13 hereof. Any authority, direction or
consent of any Person who at the time of giving such authority, direction or
consent is shown in the Register as being a Bank shall be conclusive and binding
on each present and subsequent holder, transferee or assignee of any Note or
Notes payable to such Bank or of any Note or Notes issued in exchange therefor.

      8.10. Successor Agent. Either Agent may resign at any time by giving 10
days' prior written notice thereof to the Banks and the Borrowers. Either Agent
may be removed by the Required Banks at any time by giving 10 days' prior
written notice thereof to the Agents, the other Banks and the Borrowers. Upon
any such resignation or removal of the Administrative Agent, the Required Banks
shall have the right to appoint a successor Administrative Agent. If no
successor Administrative 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 Administrative Agent may, on behalf of
the Banks, appoint a successor Administrative Agent. Each successor
Administrative Agent shall be a commercial bank or trust company organized under
the laws of the United States of America or any State thereof and having a
combined capital and surplus of at least $1,000,000,000. Upon the acceptance by
a successor Administrative Agent of its appointment as Administrative Agent
hereunder, such successor Administrative Agent shall thereupon succeed to and
become vested with all the properties, rights, powers, privileges and duties of
the former Administrative 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 Loan
Documents, but the provisions of this Agreement shall inure to its benefit as to
any actions taken or omitted by it while it was an Agent under this Agreement.
If and so long as no successor Administrative Agent shall have been appointed,
then any notice or other communication required or permitted to be given by the
Administrative Agent shall be sufficiently given if given by the Required Banks,
all notices or other communications required or permitted to be given to the
Administrative Agent shall be given to each Bank, and all payments to be made to
the Administrative Agent shall be made directly to the Borrower or Bank for
whose account such payment is made.

      8.11. Additional Administrative Agents. If the Administrative 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
Administrative Agent and the Borrowers shall execute and deliver a supplemental
agreement and all other instruments and agreements necessary or advisable, in
the opinion of the Administrative Agent, to constitute another commercial bank
or trust company, or one or more other Persons approved by the Administrative
Agent, to act as co-Administrative Agent or agent with such powers of the
Administrative Agent as may be provided in such supplemental agreement and to
vest in such bank, trust company or Person as such co-Administrative Agent or
separate agent, as the case may be, any properties, rights, powers, privileges
and duties of the Administrative Agent under this Agreement or any other Loan
Document.

      8.12. Calculations. Neither Agent shall be liable for any calculation,
apportionment or distribution of payments made by either Agent 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


                                      -33-
<PAGE>

they are determined to be entitled or, if the amount due was not paid by the
appropriate Borrower, to recover such amount from the appropriate Borrower.

      8.13. Agent's Fee. The Borrower agrees to pay to each Agent, for its
individual account, a nonrefundable Agent's fee in an amount and at such time or
times as such Agent and the Borrower have heretofore agreed.

      8.14. Funding by Administrative Agent. Unless the Administrative Agent
shall have been notified in writing by any Bank not later than the close of
business on the day before the day on which Loans are requested by the Borrower
to be made that such Bank will not make its ratable share of such Loans, the
Administrative Agent may assume that such Bank will make its ratable share of
the Loans, and in reliance upon such assumption the Administrative Agent may
(but in no circumstances shall be required to) make available to the applicable
Borrower a corresponding amount. If and to the extent that any Bank fails to
make such payment to the Administrative Agent on such date, such Bank shall pay
such amount on demand (or, if such Bank fails to pay such amount on demand, such
Borrower shall pay such amount on demand), together with interest, for the
Administrative Agent's own account, for each day from and including the date of
the Administrative Agent's payment to and including the date of repayment to the
Administrative Agent (before and after judgment) at the rate or rates per annum
applicable to such Loans. All payments to the Administrative Agent under this
Section shall be made to the Administrative Agent at its Office in Dollars in
funds immediately available at such Office, without set-off, withholding,
counterclaim or other deduction of any nature.

                                   ARTICLE IX

                                  MISCELLANEOUS

      9.01. No Implied Waiver etc. No delay or failure of either Agent or any
Bank, or the holder of any Note 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 Agents, the Banks and any holder of the Notes 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 an Agent or a Bank of any breach or default under this Agreement or any
such waiver of any provision or condition of this Agreement must be in writing
and shall be effective only to the extent in such writing specifically set
forth.

      9.02. Set-Off. In case any one or more of the Events of Default described
in Article VII hereof shall occur, the holder of any 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 held by it any debt owing by such holder to the
applicable Borrower, including without limitation any funds in any deposit
account maintained by such 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 such Borrower with such holder. Any sums obtained
by the holder of any Note issued hereunder by way of counterclaim, set-off,
banker's lien or other lien for application upon any Note held by it shall be
shared pro rata with the holders of the other Notes. 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 Borrowers and the Guarantors contained herein or
made in writing in connection


                                      -34-
<PAGE>

herewith shall survive the execution and delivery of this Agreement, the making
of Loans hereunder and the issuance of the Notes.

      9.04. Expenses and Fees; Indemnity.

      (a) Each Borrower agrees to pay or cause to be paid and to save the Agents
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 Agents 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 Loan Documents,
(ii) any requested amendments, modifications, supplements, waivers or consents
(whether or not ultimately entered into or granted) to this Agreement or any
Loan Document, and (iii) the enforcement or preservation of rights under this
Agreement or any Loan Document (including but not limited to any such costs or
expenses arising from or relating to (A) collection or enforcement of an
outstanding Loan or any other amount owing hereunder or thereunder by either
Agent or any Bank and (B) any litigation, proceeding, dispute, work-out,
restructuring or rescheduling related in any way to this Agreement or the Loan
Documents). Notwithstanding the foregoing, the Borrowers 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 Borrower 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 either Agent or any Bank to
be payable in connection with this Agreement or any other Loan Documents or any
other documents, instruments or transactions pursuant to or in connection
herewith or therewith, and the Borrower agrees to save each 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 Borrower hereby agrees to reimburse and indemnify each 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 Loan 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 Loan (and without in any way limiting the
generality of the foregoing, including any violation or breach of any Law by any
Borrower or any exercise by either Agent or any Bank of any of its rights or
remedies under this Agreement or any other Loan Document; any breach of any
representation or warranty, covenant or agreement of any Borrower); 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 Borrowers under this Section 9.04,
or any other indemnification obligation of the Borrowers hereunder or under any
other Loan Document, are unenforceable for any reason, the Borrowers hereby
agree to make the maximum contribution to the payment and satisfaction of such
obligations which is permissible under applicable Law. Notwithstanding the
foregoing, the Borrowers 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 Loan Document should be held
invalid, illegal or unenforceable in any respect, the


                                      -35-
<PAGE>

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 or under the Notes 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
this Agreement shall be deemed to have been given or made when received by the
party to whom directed. All such notices and other communications shall be in

such Bank's address on the signature pages hereof, if to the Administrative

      9.08. FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, OR ANY OTHER
MATTER RELATED THERETO MAY BE BROUGHT AND MAINTAINED IN THE COURTS OF
COMMONWEALTH OF PENNSYLVANIA OR IN THE UNITED STATES DISTRICT COURT FOR THE
WESTERN DISTRICT OF PENNSYLVANIA. EACH BORROWER HEREBY EXPRESSLY AND IRREVOCABLY

AND THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF PENNSYLVANIA
FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES

SUBJECT TO ANY GENERAL RIGHT OF APPEAL. EACH BORROWER FURTHER IRREVOCABLY
CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, TO THE
ADDRESS PROVIDED IN THIS AGREEMENT.

      9.09. WAIVER OF JURY TRIAL. TO THE EXTENT LITIGATION HEREUNDER IS BROUGHT
BEFORE A COURT IN THE UNITED STATES, THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY
AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY. EACH PARTY
ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION
FOR THIS PROVISION (AND EACH OTHER PROVISIONS OF EACH OTHER DOCUMENT RELATED
HERETO TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT
FOR EACH AGENT AND EACH BANK ENTERING INTO THIS AGREEMENT AND RELATED
AGREEMENTS.

      9.10. Governing Law. This Agreement and any other documents delivered in
connection herewith and the rights and obligations of the parties hereto and
thereto shall for all purposes be governed by and construed and enforced in
accordance with the substantive law of the Commonwealth of Pennsylvania without
giving effect to conflict of laws principles.

      9.11 Validity and Enforceability. If any stamp tax, levy, duty or fee is
imposed or payable in respect to this Agreement or the transaction contemplated
hereby or is necessary or advisable to ensure the legality, validity or
enforceability of the documents in this transaction, the Borrowers shall
promptly pay such stamp tax, levy, duty or fee. No government approval or
consent is necessary for the execution, delivery and performance of the
transactions contemplated under this Agreement and the Notes.

      9.12. Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which, when so executed and delivered, shall be an original, but all such
counterparts shall together constitute one (1) and the same instrument.

      9.13. Successors and Assigns; Participations; Assignments.

      (a) Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the Borrowers, the Banks, the Agents,
all future holders of the Notes and their respective successors and assigns,
except that no Borrower may assign or otherwise transfer any of its rights or
duties under this Agreement without the prior written consent of the Agents and
all of the Banks, and any purported assignment without such consent shall be
void.

      (b) Participations. Any Bank may, in the ordinary course of its commercial
banking business and in accordance with applicable Law, at any time sell
participations to one or more commercial banks or other Persons (each a
"Participant") in a portion of its rights and obligations under this Agreement
and the other Loan Documents (including, without limitation, all or a portion of
its Commitments and the Loans owing to it and any Notes held by it); provided,
that

            (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 each Borrower and the Administrative Agent, unless an Event of Default
      has occurred and is continuing, in which case the consent of the Borrowers
      shall not be required,

            (ii) any such Bank's obligations under this Agreement and the other
      Loan Documents shall remain unchanged,

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

            (iv) the parties hereto shall continue to deal solely and directly
      with such Bank in connection with such Bank's rights and obligations under
      this Agreement and each of the other Loan Documents,

            (v) such Participant shall be bound by the provisions of Section
      9.18 hereof, and the Bank selling such participation shall obtain from
      such Participant a written confirmation of its agreement to be so bound,

            (vi) no Participant (unless such Participant is an affiliate of such
      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 Loan
      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), (d) or (e) of Section 9.14 hereof,
      and

            (vii) a Participant shall have the right to vote regarding
      amendments to this Agreement only in connection with amendments which
      effect changes in the amount of principal, interest rates, fees and
      maturity.


                                      -37-
<PAGE>

The Borrowers agree 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 Loans outstanding from time to time; provided, that no such Participant
shall be entitled to receive any greater amount pursuant to such Sections than
the transferor Bank would have been entitled to 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
banking business and in accordance with applicable Law, at any time assign all
or a portion of its rights and obligations under this Agreement and the other
Loan Documents (including, without limitation, all or any portion of its
Commitments and Loans owing to it and any Note held by it) to any Bank, any
affiliate of a Bank or to one or more additional commercial banks or other
Persons (each a "Purchasing Bank"); provided, that

            (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 XL
      Capital and the Administrative Agent, unless an Event of Default has
      occurred and is continuing or exists, in which case the consent of XL
      Capital 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 Loan
      Documents, such assignment shall be in a minimum aggregate principal
      amount of $10,000,000 of the Commitments and Loans then outstanding,

            (iii) each such assignment shall be of a constant, and not a
      varying, percentage of each Commitment of the transferor Bank and of all
      of the transferor Bank's rights and obligations under this Agreement and
      the other Loan 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 Administrative Agent a
      duly completed Transfer Supplement (including the consents required by
      clause (i) of the preceding sentence) with respect to such assignment,
      together with any Notes subject to such assignment (the "Transferor Bank
      Notes") and a processing and recording fee of $2,500; and, upon receipt
      thereof, the Administrative 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 Administrative Agent shall record such acceptance
      in the Register. Upon such execution, delivery, acceptance and recording,
      from and after the close of business at the Administrative 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.


                                      -38-
<PAGE>

On or prior to the Transfer Effective Date specified in an Transfer Supplement,
the Borrowers, at their expense, shall execute and deliver to the Administrative
Agent (for delivery to the Purchasing Bank) new Notes evidencing such Purchasing
Bank's assigned Commitments or Loans and (for delivery to the transferor Bank)
replacement Notes in the principal amount of the Loans or Commitments retained
by the transferor Bank (such Notes to be in exchange for, but not in payment of,
those Notes then held by such transferor Bank). Each such Note shall be dated
the date and be substantially in the form of the predecessor Note. The
Administrative Agent shall mark the predecessor Notes "exchanged" and deliver
them to the Borrower. Accrued interest and accrued fees shall be paid to the
Purchasing Bank at the same time or times provided in the predecessor Notes and
this Agreement.

      (d) Register. The Administrative 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 Commitment of,
and principal amount of the Loans owing to, each Bank from time to time. The
entries in the Register shall be conclusive absent manifest error and the
Borrowers, the Administrative 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 any Borrower or any
Bank at any reasonable time and from time to time upon reasonable prior notice.

      (e) Financial and Other Information. Each Borrower authorizes each 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 Borrowers and their
affiliates which has been or may be delivered to such Person by or on behalf of
the Borrowers in connection with this Agreement or any other Loan Document or
such Person's credit evaluation of the Borrowers and their affiliates. At the
request of any Bank, each Borrower, at such Borrower's expense, shall provide to
each prospective transferee the conformed copies of documents referred to in
Section 4 of the form of Transfer Supplement.

      (f) Designated Lenders. Notwithstanding anything to the contrary contained
herein, any Bank (a "Designating Lender") may grant to an Eligible Designee
identified as such (and as a Designated Lender) in writing from time to time by
such Designating Lender to the Administrative Agent and the Borrowers, the
option to provide to the Borrowers all or any part of any Loan that such
Designating Lender would otherwise be obligated to make to any Borrower pursuant
to this Agreement; provided that nothing herein shall constitute a commitment by
such Designated Lender to make any Loan and (ii) if a Designated Lender elects
not to exercise such option or otherwise fails to provide all or any part of
such Loan, the Designating Lender shall be obligated to make such Loan pursuant
to the terms hereof. The making of a Loan by a Designated Lender hereunder shall
utilize the Committed Amount of the Designating Lender to the same extent, and
as if, such Loan were made by such Designating Lender. Each party hereto hereby
agrees that no Designated Lender shall be liable for any indemnity or similar
payment obligation under this Agreement (all liability for which shall remain
with the Designating Lender). In furtherance of the foregoing, each party hereto
hereby agrees (which agreement shall survive the termination of this Agreement)
that, prior to the date that is one year and one day after the payment in full
of all outstanding commercial paper or other senior indebtedness of any
Designated Lender, it will not institute against, or join any other person in
instituting against, such Designated Lender any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings under the laws of the United
States or any State thereof. As to any Loans or portion thereof made by it, each
Designated Lender shall have all the rights that a Bank making such Loans or
portion thereof would have had under this Agreement and otherwise; provided that
(i) its voting rights under this Agreement shall be exercised solely by its
Designating Lender, (ii) its Designating Lender shall be deemed to hold its
relevant Note as agent for its Designated Lender to the extent of the Loans or
portion thereof funded by such Designated Lender and (iii) the designation of a
Designated Lender and the funding of Loans by a Designated Lender shall in no
event (x) subject any of the Borrowers to any delay in the making of a Loan, (y)
cause or give rise to any obligation of any of the Borrowers to indemnify or
hold harmless such Designated Lender or any other person (including without
limitation pursuant to Sections 2.11 and 9.04 of this Agreement) except to the
extent such obligation would have arisen in favor of the


                                      -39-
<PAGE>

Designating Lender or another person if the Designating Lender (rather than such
Designated Lender) had made all of such Designated Lender's Loans and such
Designated Lender had not been designated as such hereunder, or (z) render the
performance of any provision of the Agreement illegal, void or unenforceable
under any provision of law. Each Designating Lender shall act as administrative
agent for its Designated Lender and give and receive notices and other
communications on behalf of its Designated Lender. Any payments for the account
of any Designated Lender shall be paid to its Designating Lender as
administrative agent for such Designated Lender and neither the Borrowers nor
either Agent shall be responsible for any Designating Lender's application of
such payments. In addition, any Designated Lender may (i) with notice to, but
without the prior written consent of, XL Capital and the Administrative Agent
and without paying any processing fee therefor, assign all or a portion of its
interests in any Loans to the Designating Lender or to any financial
institutions (consented to by XL Capital and the Administrative Agent) providing
liquidity and/or credit support to or for the account of such Designated Lender
to support the funding or maintenance of Loans and (ii) disclose on a
confidential basis any non-public information relating to its Loans or portions
thereof to any rating agency, commercial paper dealer or provider of any surety,
guarantee or credit or liquidity enhancement to such Designated Lender. This
section may not be amended without the written consent of each Designating
Lender which has designated a Designated Lender.

      9.14. Amendments and Waivers. Neither this Agreement nor any Loan Document
may be amended, modified or supplemented except in accordance with the
provisions of this Section. The Administrative Agent and the Borrowers may from
time to time amend, modify or supplement the provisions of this Agreement or any
other Loan Document for the purpose of amending, adding to, or waiving any
provisions or changing in any manner the rights and duties of any Borrower,
either Agent or any Bank. Any such amendment, modification or supplement made by
the Borrowers and the Administrative Agent in accordance with the provisions of
this Section shall be binding upon the Borrowers, each Bank and each Agent. The
Administrative Agent shall enter into such amendments, modifications or
supplements from time to 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 Committed Amount of any Bank over the amount thereof then
in effect, or extend the Expiration Date, without the written consent of each
Bank affected thereby;

      (b) Reduce the principal amount of or extend the payment of principal of
any Loan, or reduce the rate of interest or extend the time for payment of
interest borne by any Loan or extend the time for payment of or reduce the
amount of any Facility Fee or reduce or postpone the date for payment of any
other fees, expenses, indemnities or amounts payable under any Loan Document,
without the written consent of each Bank affected thereby;

      (c) Change the definition of "Required Banks" or amend this Section 9.14,
without the written consent of all the Banks;

      (d) Amend or waive any of the provisions of Article VIII hereof with
respect to either Agent, or impose additional duties upon either Agent or
otherwise adversely affect the rights, interests or obligations of either Agent,
without the written consent of such Agent; or

      (e) Amend or waive any of the provisions of Article X or release any
Guarantor from its obligations hereunder;

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.


                                      -40-

      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 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
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 Borrowers hereunder and shall apply irrespective of any
indulgence granted by the Banks.

      9.16. Records. The unpaid principal amount of the Loans owing to each
Bank, the unpaid interest accrued thereon, the interest rate or rates applicable
to such unpaid principal amount, the duration of such applicability, each Bank's
Committed Amount and the accrued and unpaid Facility Fees shall at all times be
ascertained from the records of the Administrative Agent, which shall be
conclusive absent manifest error.

      9.17 Confidentiality. Each of the Agents and the Banks agree to keep
confidential any information relating to the Borrowers received by it pursuant
to or in connection with this Agreement which is (a) information which the
Agents and the Banks reasonably expect that the applicable Borrower 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
either Agent or any Bank from disclosing such information (i) to any affiliate
that shall agree in writing for the benefit of the Borrowers 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 such 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 either 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 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 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 Borrowers 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.

      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 Administrative 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


                                      -41-
<PAGE>

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. Each 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.

                                    ARTICLE X
                                    GUARANTEE

      10.01. The Guarantee. Each of XL Insurance, XL Capital and XL Mid Ocean
(the "Guarantors") guarantees to the Agents and the Banks as hereinafter
provided the prompt payment of the Obligations of each of the Borrowers (other
than itself) (the "Guaranteed Obligations") in full when due (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), such 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 any 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 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 any Borrower for amounts paid under this Guarantee until
such time as the Banks have been paid in full, the Committed Amounts under the
Credit Agreement have been reduced to zero 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 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 any 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


                                      -42-
<PAGE>

      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, either Agent or any Bank
      as security for any of the Guaranteed Obligations shall be void or
      voidable, 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 any Guarantor) or shall be subordinated to the claims of any
      Person (including, without limitation, any creditor of any 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 Agents, the Banks or any of them 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.

      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 Agents 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 either 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
Agents 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 Loan Documents,
no 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 Borrower,
or (y) make loans or advances to any Borrower or (z) transfer any of its
properties or assets to any Borrower.

                  or the proceeds thereof, in each case held in a segregated
                  trust or other account and securing such liabilities;
                  provided, that in no case shall an Asset Accumulation Lien
                  secure Indebtedness and any Lien which secures Indebtedness
                  shall not be an Asset Accumulation Lien.

                              "Borrowers" shall mean XL Capital, XL Insurance,
                  XL Mid Ocean and XL America and "Borrower" shall mean any one
                  of them.

                              "Total Adjusted Funded Debt" shall have the

                  fiscal year or quarter to which such certificate relates (A)
                  the aggregate book value of assets which are subject to Asset
                  Accumulation Liens and the aggregate book value of liabilities
                  which are secured by Asset Accumulation Liens (it being
                  understood that the reports required by paragraphs (a) and (b)

                  (i) Total Adjusted Funded Debt to (ii) the sum of Total
                  Adjusted Funded Debt plus Consolidated Net Worth to be greater
                  than 0.35 at any time. As used herein, the term "Total

      certificate revising the prior certificate has been furnished to such
      Bank.

            (b) Organizational Documents. There shall have been delivered to the
      Administrative Agent with sufficient copies for each Bank (i) certified
      copies of the certificate of incorporation and by-laws for XL America and
      (ii) a certificate of good standing for XL America certified by the
      Secretary of State of Delaware.

            (c) Opinions of Counsel. There shall have been delivered to the
      Administrative Agent with sufficient copies for each Bank a written
      opinion addressed to the Banks, dated on or about the XL America Amendment
      Date, of Cahill Gordon & Reindel, the Borrowers' U.S. counsel, in form
      satisfactory to the Administrative Agent, which is substantially to the
      effects (insofar as XL America is concerned), but with reference to this
      Amendment and the Credit Agreement as amended hereby, set forth in the
      opinions delivered by counsel to the Borrowers on the Closing Date.

            (d) Details, Proceedings, Notes and other Documents. All legal
      details and proceedings in connection with the transactions contemplated
      by this Amendment shall be satisfactory to the Administrative Agent and
      each Bank shall have received all such counterpart originals or certified
      or other copies of the Loan Documents (including a Note issued by XL
      America for each Bank in substantially the form of Exhibit A-1 to the
      Credit Agreement, with appropriate changes) and such other documents and
      proceedings in connection with such transactions, in form and substance


                                      -5-
<PAGE>

      satisfactory to it, as the Administrative Agent or any Bank have
      reasonably requested.

            (e) Expenses. The Borrowers shall have paid all expenses and other
      compensation to be paid by them hereunder on or prior to the XL America
      Amendment Date.

            (f) Representation and Warranties. The representations and
      warranties contained in Article III of the Credit Agreement shall be true
      on and as of the XL America Amendment Date with the same effect as though
      made on and as of the XL America Amendment Date, after giving effect to
      this First Amendment (it being understood that references in such Article
      III to the Credit Agreement shall be deemed for this purpose to be
      references to this First Amendment and to the Credit Agreement as amended
      hereby) and the Administrative Agent shall have received a certificate of
      XL Capital and, insofar as is applicable to it, XL America, to such
      effect.

            SECTION 4. 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 5. 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 6. 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
all such counterparts shall constitute but one and the same instrument.

            IN WITNESS WHEREOF, the parties hereto have executed this Amendment
as of the date first above written.

References in this Agreement to "determination" by the Agent include estimates
by the Agent in good faith, without gross negligence and without manifest error
(in the case of quantitative determinations) and beliefs held by the Agent in
good faith and without gross negligence (in the case of qualitative
determinations). The words "hereof," "herein," "hereunder" and similar terms in
this Agreement refer to this Agreement as a whole and not to any particular
provision of this Agreement. The section and other headings contained in this
Agreement are for reference purposes only and shall not control or affect the
construction of this Agreement or the interpretation hereof in any respect.
Section, subsection and exhibit references are to this Agreement unless
otherwise specified.

      1.03. Accounting Principles. (a) As used herein, "GAAP" shall mean
generally accepted accounting principles as such principles shall be in effect
in the United States of America, or with respect to Brockbank Group, the United
Kingdom, and with respect to XL Europe, the Republic of Ireland, at the Relevant
Date, subject to the other provisions of this Section 1.03. As used herein,
"Relevant Date" shall mean the date a relevant computation or determination is
to be made or the date of relevant financial statements, as the case may be.

      (b) Except as otherwise provided in this Agreement, all computations and
determinations as to accounting or financial matters shall be made, and all
financial statements to be delivered pursuant to this Agreement shall be
prepared, in accordance with GAAP or SAP, as the context requires (including
principles of consolidation where appropriate), and all accounting or financial
terms shall have the meanings ascribed to such terms by GAAP or SAP, as
appropriate.

      (c) If any change in GAAP or SAP after the date of this Agreement is or
shall be required to be applied to transactions then or thereafter in existence,
and a violation of one or more financial covenants of this Agreement shall have
occurred (or in the opinion of the Required Banks would be likely to occur)
which would not have occurred or be likely to occur if no change in accounting
principles had taken place, the parties agree in such event to negotiate in good
faith an amendment 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 would have materially changed an Account Party's reported
financial results or position from that reflected in such Account Party's
financial statements most recently prepared prior to such change, such Account
Party shall notify the Agent as soon as practicable.

                          THE LETTER OF CREDIT FACILITY

      2.01. Letters of Credit.


                                       10
<PAGE>

      (a) Letter of Credit Commitments. Subject to the terms and conditions and
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
outstanding) Letters of Credit for the account of an Account Party at any time
or from time to time on or after the date hereof and to but not including the
Expiration Date (it being understood that Letters of Credit may be outstanding
for the account of one or more of the Account Parties at any time). The Issuing
Bank shall have no obligation to issue any Letters of Credit if, after such
Letters of Credit are issued, the Letter of Credit Exposure upon such issuance
would exceed the lesser of (x) the aggregate of the Banks' Letter of Credit
Participating Interest Committed Amounts and (y) the Pledged Securities
Available Amount. Each Bank's "Letter of Credit Participating Interest Committed
Amount" at any time shall be equal to the amount set forth as its "Initial
Letter of Credit Participating Interest Committed Amount" below its name on the
signature pages hereof, as such amount may have been reduced under Section
2.02(b) hereof at such time, and subject to transfer to or from another Bank as
provided in Section 9.13 hereof.

      (b) Terms of Letters of Credit. The Account Parties shall not request to
be issued, and the Issuing Bank shall have no obligation to issue, any Letter of
Credit except within the following limitations: (i) each Letter of Credit shall
have an expiration date no later than 12 months after the date of issuance
thereof; provided, however, that (x) one or more Letters of Credit with
aggregate Stated Amounts for all such Letters of Credit (determined as a Dollar
Equivalent) of up to an amount equal to 60% of the aggregate of the Banks'
Letter of Credit Participating Interest Committed Amounts may have an expiration
date no later than five years from the date of issuance and (y) any Letter of
Credit may have an "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 requested to be issued
by, and which are issued for the account of, XL Capital, XL Insurance or XL Mid
Ocean, respectively, may be stated to be issued for the account of NAC Re
Corporation, ECS, Inc., or Latin American Reinsurance Company, Ltd., in which XL
Capital, XL Insurance or XL Mid Ocean, as the case may be, has a direct or
indirect ownership interest, provided that, notwithstanding the fact that the
name of XL Capital, XL Insurance or XL Mid Ocean, as the case may be, may not
appear on the face of any such Letter of Credit, XL Capital, XL Insurance or XL
Mid Ocean, as the case may be, 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


                                       11
<PAGE>

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 XL Capital 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 Acknowledgments (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
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 XL 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. XL 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 0.07% 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. XL Capital 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, which will promptly advise
the Banks of such notice. 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


                                       12
<PAGE>

      Bank in accordance with its customary practice with respect to its
      customers generally (a "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 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 a 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 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


                                       14
<PAGE>

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 XL Capital), without, protest or demand, all of which are hereby
waived, and an action therefor 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., Pittsburgh time) or 10:00 o'clock A.M., Pittsburgh time the
following day (if notice is given after 2:00 o'clock P.M., Pittsburgh time) ,
each 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 and subject to
Section 2.04(b). 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.


                                       15
<PAGE>

      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:

      (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.

notices, reports and other information expressly required by this Agreement to

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


                                       17
<PAGE>

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
commitment hereunder 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 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),


                                       18
<PAGE>

            (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

            (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


                                       19
<PAGE>

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 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


                                       20
<PAGE>

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 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. XL 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 XL
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 XL Insurance and XL 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
Current 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 Request. 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.

      2.15. Tranches. (a) Certain Definitions. As used in this Agreement the

            hereof and such Extension Request has been consented to in writing
            by the Issuing Bank and the Required Commitment Banks, but not by
            all of the Commitment Banks, to classify Letters of Credit as

            from and to the Banks which have Letter of Credit Participating
            Interest Commitments or Letter of Credit Participating Interests, as
            applicable, with respect to such Tranche in accordance with their

            implement a Conversion to Tranche System or a Supplement to Tranche
            System.

                  "Supplement to Tranche System" means the election by XL
            Capital, at a time when the Conversion to Tranche System has been

            consented to in writing by the Issuing Bank and the Required
            Commitment Banks, but not by all of the Commitment Banks, to

            immediately prior to the first Special Expiration Date.

                  "Tranche 1 Letter of Credit" means each Letter of Credit which
            is issued prior to the first Special Expiration Date, but shall not
            include any such Letter of Credit as to which the L/C Termination
            Date has been extended to a date after the L/C Termination Date
            which was in effect on such first Special Expiration Date.


                                       22
<PAGE>

                  "Tranche 1 Letter of Credit Participating Interest Percentage"
            for each Tranche 1 Bank means such Bank's Letter of Credit
            Participating Interest Percentage immediately prior to the first
            Special Expiration Date.

            which was in effect on such second Special Expiration Date and shall
            not include any Tranche 1 Letter of Credit (it being understood that
            a Letter of Credit may change from a Tranche 1 Letter of Credit to a
            Tranche 2 Letter of Credit as a result of the extension, after the
            first Special Expiration Date, of its L/C Termination Date).

                  "Tranche 3 Letter of Credit" and "Tranche 4 Letter of Credit"
            have the meanings set forth in the definition of the term "Tranche

            Interest Commitment", "Tranche X Letter of Credit Participating
            Interest Committed Amount" and "Tranche X Letter of Credit
            Participating Interest Percentage" shall have comparable meanings.
            The term "Tranche X Letter of Credit" shall have a comparable

            Credit which is issued prior to the third Special Expiration Date,
            but shall not include any such Letter of Credit as to which the L/C
            Termination Date has been extended to a date after the L/C
            Termination Date which was in effect on such third Special

            any Tranche 1 Letter of Credit, any Tranche 2 Letter of Credit or
            any Tranche 3 Letter of Credit; (iii) the terms "Tranche 5 Letter of
            Credit", "Tranche 6 Letter of Credit", and so on shall have
            comparable meanings (it being understood that a Letter of Credit can
            change from one Tranche to another as a result of an extension of
            its L/C Termination Date).

      (b) Conversion to Tranche System. If XL Capital elects the Conversion to
Tranche System with respect to an Extension Request, the following shall occur:
(i) the Letter of Credit Participating Interest Commitments of Banks which, with
respect to such Extension Request, are Nonextending Banks shall terminate as of
the Special Expiration Date related to such Extension Request, but such
Nonextending Banks (other than Nonextending Banks which have been replaced as
contemplated by Section 2.14 hereof) shall remain parties to this Agreement and
shall retain all of their respective obligations with respect to Tranche 1
Letters of Credit and shall retain their respective Letter of Credit
Participating Interests in and with respect to Tranche 1 Letters of Credit; (ii)
from and after the Special Expiration Date related to such Extension Request,
the Letter of Credit Participating Interest Commitment of each Bank which has
consented in writing to such Extension Request shall be a "Tranche 2 Letter of

                         REPRESENTATIONS AND WARRANTIES.

Each Credit Party represents and warrants that:

      3.01. Organization and Qualification. Such Credit Party and each of its
Credit Subsidiaries is a corporation duly organized, validly existing and
(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 XL Insurance, the X.L.
Insurance Company, Ltd. Act, 1989, a copy of which has been provided to the
Agent.

      3.02. Corporate Power and Authorization. Such Credit Party and any
Subsidiary of such Credit Party which is also a Credit Party has corporate power
and authority to make and carry out this Agreement and any other Transaction
Document to which it is a party, to execute and deliver this Agreement and each
such Transaction Document, to perform its obligations hereunder and under any
such Transaction Documents and, in the case of each Credit Party which is an
Account Party, to request the issuance of Letters of Credit as provided for
herein. All such action has been duly authorized by all necessary corporate
proceedings on the part of such Credit Party.


                                       24
<PAGE>

      3.03. Financial Information. Such Credit Party (other than Brockbank
Group) has furnished to Agent, with sufficient copies for each Bank, copies of
the audited consolidated financial statements of such Credit Party and its
consolidated Subsidiaries including a consolidated and consolidating balance
sheet and related statements of income and retained earnings for the fiscal year
ending November 30, 1998. Such financial statements fairly present the financial
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 or SAP, 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 Banks in writing prior to the
Closing Date (including by disclosure in the financial statements delivered to
the Banks 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, 1998, 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 Transaction
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, except Permitted
Liens, of any nature whatsoever upon any of the property of such Credit Party
pursuant to the terms of any such agreement or instrument.

      (b) Except for the filing of the Pledge Agreement with the Registrar of
Companies in Bermuda, no authorization, consent, approval, license, exemption or
other 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
Transaction 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 (and, in the case of XL
Investments and XL Mid Ocean, the Pledge Agreement) has been duly and validly
executed and delivered by such Credit Party. This Agreement and each Transaction
Document to which it is a party constitutes 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 each 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
provisions for taxes, if any, on the books of such Credit Party are adequate for
all open years and for its current fiscal period as determined in accordance
with GAAP.


                                       25
<PAGE>

      3.09. Use of Proceeds. Such Credit Party will use any Letter of Credit
issued hereunder for its account for general corporate purposes. Such Credit
Party will make no request for a Letter of Credit hereunder for the purpose of
directly or indirectly 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. Such Credit Party 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 Credit
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 any Credit Party to the Agent or any Bank pursuant to or in connection
with this Agreement or the other Transaction Documents and the transactions
contemplated hereby and 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 the Agent or such Bank, as the case may be) 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 the Credit
Parties, 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 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 Credit
Subsidiaries is and has been in full compliance with all applicable
Environmental Laws. Such Credit Party and each of its Credit Subsidiaries have
all approvals by Official Bodies charged with the enforcement of Environmental
Laws 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.

      3.15. Year 2000 Compliance. XL Capital has (i) initiated a review and
assessment of all areas within its and each of its Subsidiaries' business and
operations (including those affected by material suppliers, vendors and
customers) that could be adversely affected by the risk that computer
applications used by XL Capital or any of its Subsidiaries (or material
suppliers, vendors and customers other than those affecting customers that may
give rise to claims under insurance policies issued by XL Capital or any
Subsidiary of XL Capital) may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999 (the "Year 2000 Problem") and (ii) developed a plan and
timetable for addressing the Year 2000 Problem on a timely basis. Based on the
foregoing, XL Capital believes that all computer applications of XL Capital and
its Subsidiaries that are material to its or any of its Subsidiaries' business
and operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1, 2000
("Year 2000 Compliant"), except to the extent that a failure to do so could not
reasonably be expected to have a Material Adverse Effect.

such Letter of Credit with the same effect as though made on and as of such date
and (ii) on the date of such Letter of Credit no Event of Default or Potential

make or cause to be made all needful and proper repairs, renewals, replacements
and improvements thereto so that the business carried on in connection therewith
may be properly conducted at all times, provided, however, that the foregoing
shall not impose on such Credit Party or any Subsidiary of such Credit Party any
obligation in respect of any property leased by such Credit Party or such
Subsidiary in addition to such Credit Party's obligations under the applicable
document creating such Credit Party's or such Subsidiary's lease or tenancy.

unpaid, might result in the creation of a Lien upon any such property (other

Party in any proceeding under the Bermuda Companies Law or Bermuda Insurance Law
or any similar Law applicable to any Credit Party, or any insolvency proceeding,
liquidation, receivership, rehabilitation, dissolution or winding-up involving
such Credit Party or such Credit Subsidiary; provided that, unless and until
foreclosure, distraint, levy, sale or similar proceedings shall have been
commenced, such Credit Party need not pay or discharge any such tax, assessment,
charge, levy or claim so long as the validity thereof is contested in good faith
and by appropriate proceedings diligently conducted and so long as such reserves
or other appropriate provisions as may be required by GAAP and SAP shall have
been made therefor and so long as such failure to pay or discharge does not have
a Material Adverse Effect.

      5.06. Financial Accounting Practices. Such Credit Party shall, and shall
cause each of its Credit Subsidiaries to, make and keep books, records and
accounts which, in reasonable detail, accurately and fairly reflect its
transactions and dispositions of its assets and maintain a system of internal

statements required under Section 5.01 hereof in conformity with GAAP and SAP,
as applicable, and to maintain accountability for assets.

      5.07. Compliance with Applicable Laws. Each Credit Party shall, and shall
cause each of its Credit Subsidiaries to, comply with all applicable Laws
(including but not limited to the Bermuda Companies Law and Bermuda Insurance
Laws) in all respects; provided that such Credit Party or any Credit Subsidiary
of such Credit Party shall not be deemed to be in violation of this Section 5.07
as a result of any failure to comply with any such Law which would not (i)
result in fines, penalties, injunctive relief or other civil or criminal
liabilities which, in the aggregate, would have a Materially Adversely Effect or
(ii) otherwise impair the ability of such Credit Party to perform its
obligations under this Agreement.

      5.08. Use of Proceeds. Each Account Party shall use the Letters of Credit
issued hereunder for its general corporate purposes.

Party hereby authorizes its financial management to discuss with any Bank the
affairs of such Credit Party.

<PAGE>

            (ii) the aggregate amount of the obligations secured by all such
      Liens on any particular property at any time purchased by such Credit
      Party, as applicable, shall not exceed 100% (if such obligations are not
      subject when created to United States income taxes) or 90% (in all other

                                  ARTICLE VIII

                                    THE AGENT

      8.01. Appointment. (a) Each Bank hereby appoints Mellon Bank, N.A. to act
as Agent for such Bank under this Agreement and the other Transaction Documents.
Each Bank hereby irrevocably authorizes the Agent to take such action on behalf
of such Bank under the provisions of this Agreement and the other Transaction
Documents, and to exercise such powers and to perform such duties, as are
expressly delegated to or required of the Agent by the terms hereof or thereof,
together with such powers as are reasonably incidental thereto. Mellon Bank,
N.A. hereby agrees to act as Agent on behalf of the Banks on the terms and
conditions set forth in this Agreement and the other Transaction Documents,
subject to its right to resign as provided in Section 8.10 hereof. Each Bank
hereby irrevocably authorizes the Agent to execute and deliver each of the
Transaction Documents and to accept delivery of such of the other Transaction
Documents as may not require execution by the Agent. Each Bank agrees that the
rights and remedies granted to the Agent under the Transaction Documents shall
be exercised exclusively by the Agent, and that no Bank shall have any right
individually to exercise any such right or remedy, except to the extent
expressly provided herein or therein.

      (b) Each Bank agrees that Mellon Bank, N. A. may act as collateral agent
in connection with a Future Collateral Allocation Transaction. As used herein,
the term "Future Collateral Allocation Transaction" means a transaction which
includes, among other things, the following elements: (i) a Credit Party shall
have arranged one or more separate financing transactions with credit providers
(which may, but need not, include any of the Banks) for which securities
entitlements in the Designated Accounts serve as collateral at a time when
securities entitlements in the Designated Accounts serve as collateral for the
Obligations under this Agreement; (ii) Mellon Bank, N. A. shall have agreed to
serve as collateral agent both for the Issuing Bank, the Agent and the Banks
under this Agreement and the Pledge Agreement and for the parties providing the
separate financing described in clause (i) of this paragraph; (iii) arrangements
shall have been made pursuant to which specific securities entitlements within
the Designated Accounts are allocated as collateral for the Obligations under
this Agreement and other specific securities entitlements within the Designated
Accounts are allocated as collateral for such other financings; and (iv) the
Required Banks and the Issuing Bank shall have approved all of such arrangements
and the documents implementing the same, including amendments to this Agreement
and the Pledge Agreement. The granting by a Credit Party to a person other than
Mellon Bank, N. A. of a security interest in securities entitlements which are
maintained in a Designated Account but which do not constitute Collateral (as
defined in the Pledge Agreement) shall not be a "Future Collateral Allocation
Transaction" and, accordingly, shall not require approval of the Required Banks
but shall be subject to the applicable provisions of the Custodian's
Acknowledgments, as defined in the Pledge Agreement.

      (c). The Arrangers shall have no duties or obligations in such capacity
under this Agreement.

      8.02. General Nature of Agent's Duties. Notwithstanding anything to the
contrary elsewhere in this Agreement or in any other Transaction Document:


                                       36
<PAGE>

            (a) The Agent 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 Agent shall
      be read into this Agreement or any Transaction Document or shall otherwise
      exist.

            (b) The duties and responsibilities of the Agent under this
      Agreement and the other Transaction Documents shall be mechanical and
      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
specified in this Agreement or any other Transaction Document as being within
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
has discretionary power to take such action, or (z) the Agent taking
discretionary action it is authorized to take under this Section (subject, in
the case of this clause (z), to the provisions of Section 8.04(a) hereof).

      8.04. General Exculpatory Provisions. Notwithstanding anything to the
contrary elsewhere in this Agreement or any other Transaction Document:

      (a) The Agent 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 caused by its own gross negligence or willful misconduct.

      (b) The Agent shall not be responsible for (i) the execution, delivery,
effectiveness, enforceability, genuineness, validity or adequacy of this
Agreement or any other Transaction Document, (ii) any recital, representation,
warranty, document, certificate, report or statement in, provided for in, or
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 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


                                       37
<PAGE>

other direct or indirect security afforded or purported to be afforded by any of
the Transaction Documents or otherwise from time to time.

      (c) The Agent 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 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
continuing basis, to provide 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 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 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.


                                       38
<PAGE>

      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
Credit 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 to the
extent resulting 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 after a proper 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
hereunder 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 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


                                       39
<PAGE>

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

      9.01. No Implied Waiver etc. No delay or failure of the Agent or any Bank
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
this Agreement or any such waiver of any provision or condition of this
Agreement must be in writing and shall be effective only to the extent in such
writing specifically set forth.

      9.02. Set-Off. In case any one or more of the Events of Default described
in Article VII hereof shall occur, each Bank shall have the right, in addition
to all other rights and remedies 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


                                       40
<PAGE>

Bank, and such Bank shall have and there is hereby created in favor of such Bank
a security interest in all deposit accounts maintained by such Credit Party with
such Bank, subject to Liens permitted under 6.03(f). Any sums obtained by any
Bank by way of counterclaim, set-off, banker's lien or other lien for
application upon any Letter of Credit Reimbursement Obligation shall be shared
pro rata with the 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
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


                                       41
<PAGE>

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
this Agreement shall be deemed to have been given or made when received by the
party to whom directed. All such notices and other communications shall be in
writing unless otherwise provided herein and shall be directed, if to a Bank, at
such Bank's address on the signature pages hereof, if to the Agent at One Mellon

BEFORE A COURT IN THE UNITED STATES, THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY
AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY. EACH PARTY

FOR THIS PROVISION (AND EACH OTHER PROVISIONS OF EACH OTHER DOCUMENT RELATED
HERETO TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT
FOR THE AGENT AND EACH BANK ENTERING INTO THIS AGREEMENT AND RELATED AGREEMENTS.

      9.10. Governing Law. This Agreement and any other documents delivered in
connection herewith and the rights and obligations of the parties hereto and
thereto shall for all purposes be governed by and construed and enforced in

giving effect to conflict of laws principles.

      9.11 Validity and Enforceability. If any stamp tax, levy, duty or fee is
imposed or payable in respect to this Agreement or the transaction contemplated
hereby or is necessary or advisable to ensure the legality, validity or
enforceability of the documents in this transaction, the Account Parties shall
promptly pay such stamp tax, levy, duty or fee. No government approval or
consent is necessary for the execution, delivery and performance of the
transactions contemplated under this Agreement.

      9.12. Counterparts. This Agreement may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which, when so executed and delivered, shall be an original, but all such
counterparts shall together constitute one (1) and the same instrument.

      9.13. Successors and Assigns; Participations; Assignments.

      (a) Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the Account Parties, the Banks, the
Agent, and their respective successors and assigns, except that no Credit Party
may assign or otherwise transfer any of its rights or duties under this
Agreement without the prior written consent of the Agent and all of the Banks,
and any purported assignment without such consent shall be void.

      (b) Participations. Any Bank may, in the ordinary course of its commercial
banking business and in accordance with applicable Law, at any time sell
participations to one or more commercial banks or other Persons (each a
"Participant") in a portion of its rights and obligations under this Agreement
and the other Transaction Documents (including, without limitation, all or a
portion of its Letter of Credit Participating Interest Commitment and Letter of
Credit Participating Interests); provided, that

            (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 XL Insurance and the Agent, unless an Event of Default has occurred and
      is continuing, in which case the consent of the Account Parties shall not
      be required,


                                       43
<PAGE>

            (ii) any such Bank's obligations under this Agreement and the other
      Transaction Documents shall remain unchanged,

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

            (iv) the parties hereto shall continue to deal solely and directly
      with such Bank in connection with such Bank's rights and obligations under
      this Agreement and each of the other Transaction Documents,

            (v) such Participant shall be bound by the provisions of Section
      9.18 hereof, and the Bank selling such participation shall obtain from
      such Participant a written confirmation of its agreement to be so bound,

            (vi) no Participant (unless such Participant is an affiliate of such
      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), (d) or (e)
      of Section 9.14 hereof, and

            (vii) a Participant shall have the right to vote regarding
      amendments 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,
that no such Participant shall be entitled to receive any greater amount
pursuant to such Sections than the transferor Bank would have been entitled to
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
banking business and in accordance with applicable Law, at any time assign all
or a portion of its rights and obligations under this Agreement and the other
Transaction Documents (including, without limitation, all or any portion of its
Letter of Credit Participating Interest Commitments and Letter of Credit
Participating Interests to any Bank, any affiliate of a Bank or to one or more
additional commercial banks or other Persons (each a "Purchasing Bank");
provided, that

            (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 XL
      Capital and the Issuing Bank, unless an Event of Default has occurred and
      is continuing or exists, in which case the consent of XL Capital 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,


                                       44
<PAGE>

            (iii) each such assignment shall be of a constant, and not a
      varying, percentage of each Commitment of the transferor Bank and of all
      of the transferor Bank's rights and obligations under this Agreement and
      the other 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 any 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 such 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;

      (c) Change the definition of "Required Banks" or amend this Section 9.14,
without the written consent of all the Banks;

      (d) Amend or waive any of the provisions of Article VII hereof, or impose
additional duties upon the Agent or otherwise adversely affect the rights,
interests or obligations of the Agent, without the written consent of the Agent;

      (e) Amend or waive any of the provisions of Article X or release any
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 XL Investments or XL Mid Ocean from all of their respective obligations
as the Grantors 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, the Agent 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 and the Agent harmless against any
deficiency in terms of Dollars in the amounts received by the Banks or the
Agent, as the case may be, 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 or the Agent, as the case may be, is able to purchase Dollars with the
amount of the Judgment Currency actually received by such Bank or the Agent, as
the case may be, 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."

                                    ARTICLE X

                                    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 any 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 any 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 voidable,
      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 voidable (including, without limitation, for the benefit of any
      creditor of any Guarantor) or shall be subordinated to the claims of any
      Person (including, without limitation, any creditor of any 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 Agents, the Banks or any of them 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, no 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 any Account Party, or (z) transfer any of
its properties or assets to any Account Party.

                  Total Funded Debt at such time plus (y) the aggregate undrawn

                  such letters of credit) issued for the account of, or
                  guaranteed by, XL Capital or any of its Consolidated
                  Subsidiaries at such time (irrespective of whether the
                  beneficiary thereof is an Affiliate).

            SECTION 2. Direction to enter into Amendments. The Required Banks
and the Issuing Bank hereby authorize and direct the Agent to enter into the
following amendments to Transaction Documents which are entered into by the
relevant Credit Parties: (i) an amendment to the Pledge Agreement whereby XL
Europe becomes a Grantor thereunder, whereby securities entitlements pledged by
XL Europe under the Pledge Agreement and otherwise meeting the requirements of
the Pledge Agreement shall be "Pledged Securities" under the Pledge Agreement
and whereby wording changes necessary to reflect three, rather than two,
Grantors under the Pledge Agreement are made, the effectiveness of such
amendment to be conditioned upon the satisfaction of conditions, to be stated in
such amendment, which are substantially similar to those applicable to XL
Investments and XL Mid Ocean as Grantors under the Pledge Agreement under
Section 4.01(a), 4.01(b)(i), 4.01(c), 4.01(d), 4.01(f) and 4.01(g) of the
Reimbursement Agreement and (ii) an amendment to one of the Custodian's
Acknowledgments referred to in the Pledge Agreement, or an additional
Custodian's Acknowledgement substantially in the form of the Custodian's
Acknowledgments referred to in the Pledge Agreement and previously delivered to
the Agent, covering custodial securities accounts maintained by XL Europe under
the Master Custody Agreement referred to in the Pledge Agreement.

amended by this Amendment, is in all respects ratified, approved and confirmed
and shall, as so amended, remain in full force and effect.

            SECTION 5. 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 6. 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
all such counterparts shall constitute but one and the same instrument.

            IN WITNESS WHEREOF, the parties hereto have executed this Amendment
as of the date first above written.

      2.01. Letters of Credit.

      (a) Letter of Credit Commitments. Subject to the terms and conditions and
relying upon the representations and warranties herein set forth, each Issuing
Bank agrees to issue Letters of Credit (each of which shall be requested by the
applicable Account Party to be one of a Set of Related Letters of Credit) for
the account of an Account Party at any time or from time to time on or after the
date hereof and to but not including the Expiration Date (it being understood
that Letters of Credit may be outstanding for the account of one or more of the
Account Parties at any time); provided, however, that the failure of an Issuing
Bank to issue a Letter of Credit which is requested by the applicable Account
Party to be one of a Set of Related Letters of Credit shall not relieve any
other Issuing Bank of its obligation to issue a Letter of Credit which is
requested by the applicable Account Party to be one of such Set of Related
Letters of Credit. No Issuing Bank shall be obligated to issue any Letter of
Credit if, after such Letter of Credit is issued, such Issuing Bank's Letter of
Credit Exposure upon such issuance would exceed the Issuing Bank's Letter of
Credit Committed Amount. Each Issuing Bank's "Letter of Credit Committed Amount"
at any time shall be equal to the amount set forth as its "Initial Letter of
Credit Committed Amount" below its name on the signature pages hereof, as such
amount may have been reduced under Section 2.02(b) hereof at such time, and
subject to transfer to or from another Issuing Bank as provided in Section 9.13
hereof.

      (b) Terms of Letters of Credit. The Account Parties shall not request to
be issued, and no Issuing Bank shall be obligated to issue, any Letter of Credit
except within the following limitations: (i) each Letter of Credit shall have an
expiration date no later than 12 months after the date of issuance thereof;
provided, however, that any Letter of Credit may have an "evergreen" provision
having substantially the effect set forth on Schedule 2.01(b) hereof, (ii) each
Letter of Credit shall be denominated in Dollars, (iii) each Letter of Credit
shall be payable only against sight drafts (and not time drafts); and (iv) each
Letter of Credit shall contain the words required by, and shall otherwise comply
with, Section 2.04 hereof.

      (c) Form of Letters of Credit. No Issuing Bank shall be obligated to issue
any letter of credit which is unsatisfactory in form, substance or beneficiary
to any of the Issuing Banks in the exercise of its reasonable judgment
consistent with its customary practice.


                                       8
<PAGE>

      (d) Letter of Credit Fee. Each Account Party shall pay or cause to be paid
to the Agent for the account of each Issuing Bank 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
by such Issuing Bank 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
0.35%. 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.

      (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 support the Account Parties' reinsurance program
with NAC Re Corporation in the ordinary course of business of such Account
Party.

      (f) Administration Fees. Each Account Party shall pay to the Agent, for
the account of each Issuing Bank, such other administration, maintenance,
amendment, drawing and negotiation fees as are customarily charged by such
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 Banks to XL Insurance) or are otherwise agreed between such Issuing Bank
and the Account Parties.

      (g) Arrangement Fee. XL Capital agrees to pay to Mellon an arrangement fee
in the amount and at the time previously agreed between XL Capital and Mellon.

      2.02. Commitment Fee; Reduction of the Committed Amounts.

      (a) Commitment Fee. XL Insurance agrees to pay to the Agent for the
account of each Issuing 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 0.07% payable on the unused portion of such Issuing Bank's Letter
of Credit 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. XL Capital may at any time or from
time to time reduce Pro Rata the Letter of Credit Committed Amounts of the
Issuing Banks to an aggregate amount (which may be zero) not less than the
Letter of Credit Exposure. Any reduction of the Letter of Credit Committed
Amounts shall be in an aggregate minimum amount of $5,000,000 and in an amount
which is an integral multiple of $1,000,000. Reduction of the Letter of Credit
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, which
will promptly advise the Issuing Banks of such notice. After the date specified
in such notice, the Commitment Fee shall be calculated upon the Letter of Credit
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 Banks to issue a Set of
Related Letters of Credit by:

            (i) delivering to the Agent a written request to such effect (an "LC
      Request"), specifying the date on which such Set of Related Letters of
      Credit is to be issued, the expiration date thereof, the aggregate amount
      requested (the "LC Request Amount") and the Stated Amount of each Related
      Letter of Credit (which Stated Amount shall be equal to the applicable
      Issuing Bank's Pro Rata share of the LC Request Amount), and


                                       9
<PAGE>

            (ii) delivering to each Issuing Bank a completed application, in the
      form annexed hereto as Exhibit E, or in such other form as is from time to
      time be required by each such Issuing Bank in accordance with its
      customary practice with respect to its customers generally (a "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 Agent shall promptly notify each Issuing
Bank and furnish to each Issuing Bank the proposed form of Letter of Credit to
be issued and the Stated Amount and term of such proposed Letter of Credit to be
issued by such Issuing Bank. The Agent shall determine, as of the close of
business on the Business Day before such proposed issuance, whether such
proposed Set of Related Letters 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 Issuing Banks have given notice to the Agent to
cease issuing Letters of Credit pursuant to Section 2.03(c) hereof or the the
Agent shall have received written notice from an Account Party that the
conditions set forth in Section 4.02(a) are not satisfied, the Agent shall
notify each Issuing Bank (in writing or by telephone promptly confirmed in
writing) that such Issuing Bank is not obligated to issue such Letter of Credit.
If an 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, by a request sent to the Agent, request the Issuing Banks to extend (or
request the Issuing Banks to permit the extension, by failing to provide a
nonrenewal notice to the beneficiary, of) the expiration date of a Set of
Related Letters of Credit or increase (or, with the consent of the beneficiary,
decrease) the Stated Amounts of or the amounts available to be drawn on such
Related Letters of Credit; provided however, that any such increase (or
decrease, as the case may be) shall be made Pro Rata. Such extension or increase
shall for all purposes hereunder be treated as though such Account Party had
requested issuance of replacement Related Letters of Credit (except only that
the Issuing Banks may, if they all so elect, issue a notice of extension or
increase with respect to an outstanding Set of Related Letters of Credit in lieu
of issuing a new Set of Related Letters of Credit in substitution for an
outstanding Set of Related Letters of Credit).

      (c) Limitations on Issuance. As between the Agent, on the one hand, and
the Issuing 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 Issuing 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 Banks 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 Issuing Banks, in authorizing
an Issuing Bank to issue such a 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. Certain Provisions in Letters of Credit. (a) The first Set of
Related Letters of Credit issued hereunder shall be in substantially the form
set forth on Exhibit F hereto.

      (b) Each Letter of Credit requested to be issued hereunder shall be
requested to contain the following language, with the blanks appropriately
filled:

            This letter of credit is being issued at substantially the same time
            as each of ________________________ [name other Issuing Banks] is
            issuing its letter of credit to the Beneficiary for the account of
            the Account Party (this letter of credit and all such other letters
            of credit being referred to collectively as the "Related Letters of
            Credit") and the aggregate stated amount of the Related Letters of
            Credit is $_____________.


                                       10
<PAGE>

In addition, each Letter or Credit shall provide that drawings on such Letter of
Credit must be accompanied by a certificate of the beneficiary thereof which
states as follows:

            Concurrently with this drawing, Beneficiary is drawing on each other
            Related Letter of Credit referred to in the letter of credit to
            which this drawing relates. The respective amounts of all such
            concurrent drawings on the Related Letters of Credit (including the
            letter of credit to which this drawing relates) are ratable in
            accordance with the respective stated amounts of the respective
            Related Letters of Credit.

      2.05. Account Party's Reimbursement Obligations. Each Account Party hereby
agrees to reimburse each Issuing Bank, by making payment to the Agent for the
account of such Issuing Bank in accordance with Section 2.11(a) hereof on the
date of each payment made by such 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 XL Capital), without, protest or demand, all of which are hereby
waived, and an action therefor shall immediately accrue. Each Account Party
agrees that it will make such payment to the Agent for the account of the
applicable Issuing Bank in the same currency as the currency of the payment by
such 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 applicable Issuing Bank, on demand, interest on any Letter of
Credit Unreimbursed Draws for each day from and including the date of such
payment by such 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. If the Agent receives payment on account of Letter of
Credit Reimbursement Obligations in an amount less than the full amount of
Letter of Credit Reimbursement Obligations then outstanding and owing to the
Issuing Banks, the amount so received will be applied by the Agent ratably in
accordance with the respective amounts of Letters of Credit Reimbursement
Obligations owing to the respective Issuing Banks.

      2.06 Extensions of Expiration Date. XL Capital may, at its option, give
the Agent and the Issuing Banks written notice (an "Extension Request") at any
time not more than ninety days, nor less than thirty days, prior to the
Expiration Date in effect at such time (the "Current Expiration Date") of XL
Capital's desire to extend the Expiration Date to a date which is not later than
364 days after the Current Expiration Date. Each Issuing Bank which agrees to
such Extension Request shall deliver to the Agent its express written consent
thereto no later than fifteen days prior to the Current Expiration Date. No
extension shall become effective unless the express written consent thereto by
all of the Issuing Banks is received by the Agent on or before the fifteenth day
prior to the Current Expiration Date. If all of the Issuing 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 Request.

      2.07. Obligations Absolute. The payment obligations of the Account Parties
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:

      (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), any Issuing 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;


                                       11
<PAGE>

      (d) payment by an 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 an 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 such 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 an Issuing Bank.

Each Account Party bears the risk of, and neither the Issuing Banks, nor any of
their directors, officers, employees or agents, 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 any 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
respective Issuing Banks under, any 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 Banks under, this Agreement, the Transaction Documents, and applicable
Law. 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 Banks.

      (a) General. No Issuing Bank shall have any 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 any Issuing
Bank shall be read into this Agreement or any Transaction Document or shall
otherwise exist. The duties and responsibilities of the Issuing Banks to the
other Bank Parties under this Agreement and the other Transaction Documents
shall be mechanical and administrative in nature, and no Issuing Bank shall have
a fiduciary relationship in respect of any Bank Party or any other Person. No
Issuing Bank shall 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 caused by its own gross negligence or willful misconduct. No Issuing Bank
shall 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. No Issuing Bank shall be under any obligation,
either initially or on a continuing basis, to provide the Agent or any other
Bank Party 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. No
Issuing Bank shall be responsible for the execution, delivery, effectiveness,
enforceability, genuineness, validity or adequacy of this Agreement or any other
Transaction Document.

      (b) Administration. Each 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
no Issuing


                                       12
<PAGE>

Bank shall have any duty to verify the identity or authority of any Person
giving such notice or other communication. Each Issuing Bank may consult with
legal counsel (including, without limitation, in-house counsel for such 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 no
Issuing Bank shall 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 any 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 such Issuing Bank may conclusively rely upon such
certificate. No Issuing Bank shall be deemed to have any knowledge or notice of
the occurrence of any Event of Default or Potential Default unless such Issuing
Bank has received notice from a Bank Party 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 any Issuing Bank receives such a
notice, such Issuing Bank shall give prompt notice thereof to the Agent.

      (c) Issuing Bank in its Individual Capacity. Each Issuing Bank 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 such Issuing Bank were not an 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
Issuing 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 Issuing 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 Issuing 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


                                       13
<PAGE>

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 Issuing 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 Issuing
      Bank imposed by the jurisdictions (federal, state and local) in which such
      Issuing 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, any Issuing 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 Issuing Bank or
      (B) otherwise applicable to the obligations of any Issuing Bank under this
      Agreement, or

            (iv) imposes upon any Issuing 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
Issuing Bank or, in the case of clause (iii) hereof, any Person controlling an
Issuing 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 Issuing Bank's or controlling
Person's capital, taking into consideration such Issuing 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 Issuing Bank deems to be material, such Issuing 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 Issuing Bank (which determination
shall be conclusive) to be necessary to compensate such Issuing Bank for such
increase, reduction or imposition. Such amount shall be due and payable by any
applicable Account Party to such Issuing 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 Issuing 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 Issuing 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 Issuing 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 Issuing Bank, income or
      franchise taxes imposed on the Agent or such Issuing Bank by the
      jurisdiction under the laws of which the Agent or such Issuing Bank is
      organized or any political subdivision or taxing authority thereof or


                                       14
<PAGE>

      therein or as a result of a connection between such Issuing 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 Issuing Bank, income or franchise taxes
      imposed by any jurisdiction in which such Issuing 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 Issuing 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 Issuing Bank shall be increased to the extent necessary to yield to the
Agent or such Issuing 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
Issuing 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
an Issuing 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
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 Issuing 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 such 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 Issuing 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 Issuing Bank (including additional
Taxes attributable to such refund, as determined by the Agent or such Issuing
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 an Issuing Bank shall, upon demand, pay to the Agent
or such Issuing Bank any amount paid over to such Account Party by the Agent or
such Issuing Bank (plus penalties, interest or other charges) in the event the
Agent or such Issuing 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 Issuing Bank, including,
without limitation, tax returns.

      (b) Indemnity. Each Account Party hereby indemnifies the Agent and each of
the Issuing 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 Issuing 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 Issuing Bank as a result of any failure to pay such Taxes, except
by reason of unreasonable delay by the Agent or such Issuing 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 Issuing Bank or
the Agent, as the case may be, makes written demand therefor.

      (c) Withholding and Backup Withholding. Each Issuing 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


                                       15
<PAGE>

            (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 Issuing 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 Issuing 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 Issuing 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 Issuing Bank from duly completing and
delivering any such letter or form with respect to it and such Issuing Bank
advises 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.

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES.

Each Credit Party represents and warrants that:

      3.01. Organization and Qualification. Such Credit Party and each of its
Subsidiaries is a corporation duly organized, validly existing and (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 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 XL Insurance, the X.L.
Insurance Company, Ltd. Act, 1989, a copy of which has been provided to the
Agent.

      3.02. Corporate Power and Authorization. Such Credit Party and any
Subsidiary of such Credit Party which is also a Credit Party has corporate power
and authority to make and carry out this Agreement and any other Transaction
Document to which it is a party, to execute and deliver this Agreement and each
such Transaction Document, to perform its obligations hereunder and under any
such Transaction Documents and, in the case of each Credit Party which is an
Account


                                       16
<PAGE>

Party, to request the issuance of Letters of Credit as provided for herein. All
such action has been duly authorized by all necessary corporate proceedings on
the part of such Credit Party.

      3.03. Financial Information. Such Credit Party has furnished to Agent,
with sufficient copies for each Issuing Bank, copies of the audited consolidated
financial statements of such Credit Party and its consolidated Subsidiaries
including a consolidated and consolidating balance sheet and related statements
of income and retained earnings for the fiscal year ending December 31, 1998.
Such financial statements fairly present the financial 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 or SAP, 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 Issuing Banks in writing
prior to the Closing Date (including by disclosure in the financial statements
delivered to the Issuing Banks 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 December 31, 1998, 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 Transaction
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, except Permitted
Liens, of any nature whatsoever upon any of the property of such Credit Party
pursuant to the terms of any such agreement or instrument.

      (b) No authorization, consent, approval, license, exemption or other
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
Transaction 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 and each
Transaction Document to which it is a party constitutes 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
provisions for taxes, if any, on the books of such Credit Party are adequate for
all open years and for its current fiscal period as determined in accordance
with GAAP.


                                       17
<PAGE>

      3.09. Use of Proceeds. Such Credit Party will use any Letter of Credit
issued hereunder for its account solely to support the Account Parties'
reinsurance program with NAC Re Corporation in the ordinary course of business.
Such Credit Party will make no request for a Letter of Credit hereunder for the
purpose of directly or indirectly 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. Such Credit Party 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 any Credit Party to the Agent or any Issuing Bank pursuant to or in
connection with this Agreement or the other Transaction Documents and the
transactions contemplated hereby and 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 the Agent or such Issuing Bank, as the
case may be) 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 the Credit Parties, 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 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
Environmental Laws. Such Credit Party and each of its Subsidiaries have all
approvals by Official Bodies charged with the enforcement of Environmental Laws
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.

      3.15. Year 2000 Compliance. XL Capital has (i) initiated a review and
assessment of all areas within its and each of its Subsidiaries' business and
operations (including those affected by material suppliers, vendors and
customers) that could be adversely affected by the risk that computer
applications used by XL Capital or any of its Subsidiaries (or material
suppliers, vendors and customers other than those affecting customers that may
give rise to claims under insurance policies issued by XL Capital or any
Subsidiary of XL Capital) may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999 (the "Year 2000 Problem") and (ii) developed a plan and
timetable for addressing the Year 2000 Problem on a timely basis. Based on the
foregoing, XL Capital believes that all computer applications of XL Capital and
its Subsidiaries that are material to its or any of its Subsidiaries' business
and operations are reasonably expected on a timely basis to be able to perform
properly date-sensitive functions for all dates before and after January 1, 2000
("Year 2000 Compliant"), except to the extent that a failure to do so could not
reasonably be expected to have a Material Adverse Effect.

                                   ARTICLE IV

                                   CONDITIONS

      4.01. Effectiveness. The respective obligations of the Issuing Banks to
issue Letters of Credit shall be subject to the following conditions:

      (a) Proceedings and Incumbency. There shall have been delivered to the
Agent with sufficient copies for each Issuing Bank a certificate with respect to
each Credit Party in form and substance satisfactory to the Agent dated the
Closing Date and signed on behalf of each Credit Party by the Secretary or an
Assistant Secretary of such Credit Party certifying as to: (i) true copies of
all corporate action taken by such Credit Party relative to this Agreement and
the other Transaction Documents applicable to it including but not limited to
that described in Section 3.02 hereof (with respect to the Guarantors, such
corporate action shall include board findings satisfactory to the Arranger's
Bermuda counsel) and (ii) 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 Transaction Documents applicable to it. Each Issuing
Bank may conclusively rely on such certificates unless and until a later
certificate revising the prior certificate has been furnished to such Issuing
Bank.

      (b) Organizational Documents. There shall have been delivered to the Agent
with sufficient copies for each Issuing Bank (i) certified copies of the
articles of incorporation or memorandum of association and by-laws or other
equivalent organizational documents for each Credit Party and (ii) a certificate
of good standing for each Credit Party certified by the appropriate Official
Body of its place of organization.

obligation to become due prior to its stated maturity or to terminate its
commitment under such agreement;

of sixty days; or a decree or order of a court having jurisdiction in the
premises for the appointment of a receiver or liquidator or trustee or assignee
in bankruptcy or insolvency of such Credit Party or a substantial part of its
property, or for the winding up or liquidation of its affairs, shall have been

Party in furtherance of any of the aforesaid purposes.

If an Event of Default shall occur then the Issuing Banks shall be under no
further obligation to issue Letters of Credit hereunder and the Agent may, and
upon written request of the Required Issuing Banks shall, exercise any or all
remedies available to it. Without limiting the generality of the foregoing, if
an Event of Default shall have occurred and be continuing, the Agent may, and
upon the request of the Required Issuing Banks shall, make demand upon the
applicable Account Party to, and forthwith upon such demand the applicable
Account Party will, pay to the Agent as cash collateral for the ratable benefit
of the Issuing Banks, in same day funds at the Agent's office designated in such

time during the continuance of an Event of Default the Agent determines that
such funds are subject to any right or claim of any Person other than the Agent
and the Issuing Banks or that the total amount of such funds is less than the
aggregate Letter of Credit Undrawn Availability of all Letters of Credit issued
for the account of an Account Party, such Account Party will, forthwith upon
demand by the Agent, pay to the Agent as additional cash collateral for the
ratable benefit of the Issuing Banks an amount equal to the excess of (a) such
aggregate Letter of Credit Undrawn Availability over (b) the total amount of
funds, if any, that the Agent determines to be free and clear of any such right
or claim. Upon the drawing of any Letters of Credit, such funds shall be applied
to reimburse the Issuing Banks, ratably, to the extent permitted by applicable
law.

      expressly set forth in this Agreement and the other Transaction Documents,
      and no implied duties or responsibilities on the part of the Agent shall

      exist.

            (b) The duties and responsibilities of the Agent under this
      Agreement and the other Transaction Documents shall be mechanical and
      administrative in nature, and the Agent shall not have a fiduciary
      relationship in respect of any Issuing Bank.

            (c) The Agent is and shall be solely the agent of the Issuing 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 Issuing
      Banks as provided in this Agreement and the other Transaction Documents).

            (d) The Agent shall be under no obligation to take any action

      require the Agent to qualify to do business in any jurisdiction where it
      is not then so qualified.

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
Issuing 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 Issuing 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

Section (subject, in the case of this clause (z), to the provisions of Section
8.04(a) hereof).

      8.04. General Exculpatory Provisions. Notwithstanding anything to the
contrary elsewhere in this Agreement or any other Transaction Document:

      (b) The Agent shall not be responsible for (i) the execution, delivery,
effectiveness, enforceability, genuineness, validity or adequacy of this
Agreement or any other Transaction Document, (ii) any recital, representation,

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

<PAGE>

      (c) The Agent 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 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
continuing basis, to provide any Issuing 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 or any other Transaction Document to be furnished by the Agent to
such Issuing 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 Issuing Bank, such matter may be established by a certificate of such
Credit Party or Issuing 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 an Issuing 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 Agent receives such a notice,
the Agent shall give prompt notice thereof to each Issuing Bank.

      8.06. Issuing Bank Not Relying on Agent or Issuing Banks. Each Issuing
Bank acknowledges as follows: (a) neither the Agent nor any other Issuing Bank
has made any representations or


                                       29
<PAGE>

warranties to it, and no act taken hereafter by the Agent or any other Issuing
Bank shall be deemed to constitute any representation or warranty by the Agent
or such other Issuing Bank to it; (b) it has, independently and without reliance
upon the Agent or any other Issuing 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
Issuing 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 Issuing Bank agrees to reimburse and indemnify
the Agent, in its capacity as 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 Credit Parties to do so), ratably in accordance with
their respective Letter of Credit Committed Amounts, 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 Issuing Bank shall be
liable for any portion of such amounts, 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 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 Issuing Bank fails to pay any such amount
after a proper 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
hereunder 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
Issuing Bank and may exercise the same as though it were not the Agent, and the
terms "Issuing 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 Issuing Banks and the Account Parties. The
Agent may be removed by the Required Issuing Banks at any time by giving 10
days' prior written notice thereof to the Agent, the other Issuing Banks and the
Account Parties. Upon any such resignation or removal, the Required Issuing
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 Issuing 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 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


                                       30
<PAGE>

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 Issuing
Banks, all notices or other communications required or permitted to be given to
the Agent shall be given to each Issuing Bank, and all payments to be made to
the Agent shall be made directly to the Account Parties or Issuing 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 Issuing 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 Issuing Bank to whom payment was
due but not made shall be to recover from the other Issuing 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. Documentation Agent. Fleet National Bank shall not, in the capacity
of Documentation Agent (as opposed to the capacity of Issuing Bank) have any
duties or rights hereunder.

                                   ARTICLE IX

                                  MISCELLANEOUS

      9.01. No Implied Waiver etc. No delay or failure of the Agent or any
Issuing Bank 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 Issuing 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 an Issuing Bank of any breach or
default under this Agreement or any such waiver of any provision or condition of
this Agreement must be in writing and shall be effective only to the extent in
such writing specifically set forth.

      9.02. Set-Off. In case any one or more of the Events of Default described
in Article VII hereof shall occur, each Issuing Bank shall have the right, in
addition to all other rights and remedies 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 Issuing Bank to the applicable Credit Party,
including without limitation any funds in any deposit account maintained by such
Credit Party with such


                                       31
<PAGE>

Issuing Bank, and such Issuing Bank shall have and there is hereby created in
favor of such Issuing Bank a security interest in all deposit accounts
maintained by such Credit Party with such Issuing Bank, subject to Liens
permitted under 6.03(f). 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 Issuing 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 Issuing 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 Issuing 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 an Issuing
Bank (in its capacity as such) which were incurred by such Issuing Bank in
connection with any litigation, proceeding or other dispute relating solely to a
claim made against such Issuing Bank by one or more of the other Issuing 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 Issuing 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 Issuing 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 Issuing 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 Issuing Bank of any of its rights or remedies
under 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


                                       32
<PAGE>

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 an Issuing Bank (in its
capacity as such) which were incurred by such Issuing Bank in connection with
any litigation, proceeding or other dispute relating solely to a claim made
against such Issuing Bank by one or more of the other Issuing Banks.

      9.05. Severability; Inconsistent Provisions. 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. In the event of any inconsistency between the terms of
this Agreement and the terms of any Letter of Credit Application or Continuing
Letter of Credit Agreement, the terms of this Agreement shall control.

      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
this Agreement shall be deemed to have been given or made when received by the
party to whom directed. All such notices and other communications shall be in
writing unless otherwise provided herein and shall be directed, if to an Issuing
Bank, at such Issuing Bank's address on the signature pages hereof, if to the

Credit Party.

HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY
OTHER TRANSACTION DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, OR ANY
OTHER MATTER RELATED THERETO MAY BE BROUGHT AND MAINTAINED IN THE COURTS OF
COMMONWEALTH OF PENNSYLVANIA OR IN THE UNITED STATES DISTRICT COURT FOR THE
WESTERN DISTRICT OF PENNSYLVANIA. EACH CREDIT PARTY HEREBY EXPRESSLY AND

PENNSYLVANIA AND THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF

WITH SUCH LITIGATION, SUBJECT TO ANY GENERAL RIGHT OF APPEAL. EACH CREDIT PARTY

      9.09. WAIVER OF JURY TRIAL. TO THE EXTENT LITIGATION HEREUNDER IS BROUGHT
BEFORE A COURT IN THE UNITED STATES, THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY
AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY. EACH PARTY
ACKNOWLEDGES AND AGREES THAT IT

OTHER PROVISIONS OF EACH OTHER DOCUMENT RELATED HERETO TO WHICH IT IS A PARTY)
AND THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE AGENT AND EACH ISSUING
BANK ENTERING INTO THIS AGREEMENT AND RELATED AGREEMENTS.

      (a) Successors and Assigns. The provisions of this Agreement shall be
binding upon and inure to the benefit of the Account Parties, the Issuing Banks,

            (i) any such participation sold to a Participant which is not an
      Issuing Bank, an affiliate of an Issuing Bank or a Federal Reserve Bank
      shall be made only with the consent (which in each case shall not be
      unreasonably withheld) of XL Capital and the Agent, unless an Event of

<PAGE>

            (vi) no Participant (unless such Participant is an affiliate of such
      Issuing Bank, or is itself a Issuing Bank) shall be entitled to require
      such Issuing Bank to take or refrain from taking action under this

      Issuing Bank may agree with such Participant that such Issuing Bank will
      not, without such Participant's consent, take action of the type described
      in subsections (a), (b), (c), (d) or (e) of Section 9.14 hereof, and

            (vii) a Participant shall have the right to vote regarding

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

            (ii) if an Issuing 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 such Issuing Bank's Letter of
      Credit Commitments and Letter of Credit Exposure then outstanding,

            (iii) each such assignment shall be of a constant, and not a
      varying, percentage of each Commitment of the transferor Issuing Bank and
      of all of the transferor Issuing Bank's rights and obligations under this
      Agreement and the other 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 Issuing 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 an Issuing 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


                                       35
<PAGE>

      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 an Issuing Bank hereunder, and

            (y) the transferor Issuing 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 Issuing Bank's rights and obligations under this
      Agreement, such transferor Issuing 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 Issuing Banks and the Letter of
Credit Commitment of, and the amount of the Letter of Credit Committed Amount
of, each Issuing Bank from time to time. The entries in the Register shall be
conclusive absent manifest error and the Account Parties, the Agent and the
Issuing Banks may treat each person whose name is recorded in the Register as an
Issuing Bank hereunder for all purposes of the Agreement. The Register shall be
available for inspection by any Account Party or any Issuing 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 Issuing 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 Issuing Bank, a Credit Party, at
such 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 Issuing 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 Issuing Bank and the
Agent. The Agent shall enter into such amendments, modifications or supplements
from time to time as directed by the Required Issuing 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 Committed Amount of any Issuing Bank
over the amount thereof then in effect, or extend the Expiration Date, without
the written consent of each Issuing 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 Issuing Bank affected
thereby;

      (c) Change the definition of "Required Issuing Banks" or amend this
Section 9.14, without the written consent of all the Issuing Banks;


                                       36
<PAGE>

      (d) Amend or waive any of the provisions of Article VII hereof, or impose
additional duties upon the Agent or otherwise adversely affect the rights,
interests or obligations of the Agent, without the written consent of the Agent;
or

      (e) Amend or waive any of the provisions of Article X or release any
Guarantor from its obligations hereunder without the written consent of all the
Issuing 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.

      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
Issuing Banks, the Agent 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 Issuing Banks and the Agent harmless against
any deficiency in terms of Dollars in the amounts received by the Issuing Banks
or the Agent, as the case may be, 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 Issuing Bank or the Agent, as the case may be, is able to purchase
Dollars with the amount of the Judgment Currency actually received by such
Issuing Bank or the Agent, as the case may be, 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 Issuing Banks.

      9.16. Records. The amount of outstanding Letters of Credit, each Issuing
Bank's Letter of Credit 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 Issuing 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 Issuing 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 Issuing 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 Issuing 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 Issuing 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 Issuing 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 Issuing 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


                                       37
<PAGE>

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 Issuing Banks hereby agree among
themselves that if any Issuing 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 Issuing
Banks in greater proportion than any such amount received by any other Issuing
Bank, then the Issuing Bank receiving such proportionately greater payment shall
notify each other Issuing 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 Issuing
Banks. The Issuing 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 Issuing Banks a participation in the applicable
Obligations owed to such other Issuing Banks in such amount as shall result in a
ratable sharing by all Issuing Banks of such excess amount (and to such extent
the receiving Issuing Bank shall be a Participant). If all or any portion of
such excess amount is thereafter recovered from the Issuing 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 Issuing 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 an
Issuing Bank hereunder.

                                    ARTICLE X

                                    GUARANTEE

      10.01. The Guarantee. Each of the Guarantors hereby irrevocably,
unconditionally and absolutely guarantees to the Agent and the Issuing 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 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 any 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


                                       38
<PAGE>

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
Issuing Banks have been paid in full, no Letter of Credit is outstanding, the
Letter of Credit 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 Issuing 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 any 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 Issuing
      Bank as security for any of the Guaranteed Obligations shall be void or
      voidable, or shall fail to attach or be perfected or the Agent or any
      Issuing Bank shall fail to realize on any collateral security; 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 any Guarantor) or shall be subordinated to the claims of any
      Person (including, without limitation, any creditor of any 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 Agents, the Issuing Banks or any of them 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 Issuing 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 Issuing 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


                                       39
<PAGE>

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 Issuing 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, no 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 any Account Party, or (z) transfer any of
its properties or assets to any Account Party.

                  FIRST AMENDMENT TO LETTER OF CREDIT FACILITY
                           AND REIMBURSEMENT AGREEMENT

            THIS FIRST AMENDMENT TO LETTER OF CREDIT FACILITY AND REIMBURSEMENT
AGREEMENT, dated as of February 25, 2000 (this "Amendment"), by and among XL

the "XL Parties"), MELLON BANK, N.A., DEUTSCHE BANK AG, NEW YORK AND/OR CAYMAN
ISLANDS BRANCHES, FIRST UNION NATIONAL BANK, FLEET NATIONAL BANK and BANK ONE,
NA (MAIN OFFICE CHICAGO) as Issuing Banks (the "Issuing Banks") and MELLON BANK,
N.A., as Agent (the "Agent").

                              W I T N E S S E T H:

            WHEREAS, the XL Parties, the Issuing Banks and the Agent are parties
to a Letter of Credit Facility and Reimbursement Agreement, dated as of December
30, 1999 (the "Reimbursement Agreement"), pursuant to which the Issuing Banks
have agreed, on the terms and subject to the conditions described therein, to
extend credit to certain of the XL Parties by issuing letters of credit for the
account of such XL Parties; and

            WHEREAS, the XL Parties have requested the Issuing Banks to make
certain additional changes to the Reimbursement Agreement;

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

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

<PAGE>

            (a) Section 1.01 of the Reimbursement Agreement is hereby amended by
      adding thereto, in appropriate alphabetical sequence, the following
      definitions:

                        "Asset Accumulation Lien" means a Lien on amounts
                  received, and on actual and imputed investment income on such
                  amounts received, relating and identified to specific
                  insurance payment liabilities or to liabilities arising in the

                  as an insurance or reinsurance company or corporate member of
                  Lloyd's or as a provider of financial services or contracts,

                              The Letters of Credit

      SECTION 2.01. Commitment. Subject to the terms and conditions set forth
herein, the Issuing Bank agrees to issue (or extend, modify or amend) Letters of
Credit for the accounts of the Applicants from time to time during the
Availability Period in an aggregate principal amount not to exceed the
Commitment. Within the foregoing limits and subject to the terms and conditions
set forth herein, the Applicants may reduce or cancel Letters of Credit or
request the renewal of Letters of Credit or the issuance of new Letters of
Credit. The Letters of Credit shall be used for general corporate purposes.

      SECTION 2.02. Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. (a) To request the issuance of a Letter of Credit (or the amendment,
renewal or extension of an outstanding Letter of Credit), an Applicant shall
hand deliver or telecopy (or transmit by electronic communication, if
arrangements for doing so have been approved by the Issuing Bank) to the Issuing
Bank (reasonably in advance of the requested date of issuance, amendment,
renewal or extension) a notice requesting the issuance of a Letter of Credit, or
identifying the Letter of Credit to be amended, renewed or extended, the date of
issuance (which shall be a Business Day), amendment, renewal or extension, the
date on which such Letter of Credit is to expire (which shall comply with
paragraph (b) of this Section), the amount of such Letter of Credit, the name
and address of the beneficiary thereof and such other information as shall be
necessary to prepare, amend, renew or extend such Letter of Credit. An Applicant
also shall submit a letter of credit application (an "Application") on the
Issuing Bank's standard form in connection with any request for a Letter of
Credit; provided that in the event of any inconsistency between the terms and
conditions of this Agreement and the terms and conditions of any Application,
the terms and conditions of this Agreement shall control. A Letter of Credit
shall be issued, amended, renewed or extended only if (and upon issuance,
amendment, renewal or extension of each Letter of Credit the relevant Applicant
shall be deemed to represent and warrant that), after giving effect to such
issuance, amendment, renewal or extension the LC Exposure shall not exceed the
Commitment.

      (b) Expiration Date. Each Letter of Credit shall expire at or prior to the
close of business on the earlier of (i) the date one year after the date of the
issuance of such Letter of Credit (or, in the case of any renewal or extension
thereof, one year after such renewal or extension) and (ii) the date that is
five Business Days prior to the Commitment Termination Date.

      (c) Reimbursement. If the Issuing Bank shall make any LC Disbursement in
respect of a Letter of Credit, the Applicant thereof shall reimburse such LC
Disbursement by paying to the Issuing Bank an amount equal to such LC
Disbursement not later than 12:00 noon, New York City time, on the date that
such LC Disbursement is made, if such Applicant shall have received notice of
such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or,
if such notice has not been received by such Applicant prior to such time on
such date, then not later than 12:00 noon, New York City time, on (i) the
Business Day that such Applicant receives such notice, if such notice is
received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii)
the Business Day immediately following the day that


                                       5
<PAGE>

such Applicant receives such notice, if such notice is not received prior to
such time on the day of receipt.

      (d) Obligations Absolute. The Applicants' obligations to reimburse LC
Disbursements as provided in paragraph (c) of this Section shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement under any and all circumstances whatsoever and
irrespective of (i) any lack of validity or enforceability of any Letter of
Credit or this Agreement, or any term or provision therein, (ii) any draft or
other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid in any respect or any statement therein being untrue or
inaccurate in any respect, (iii) payment by the Issuing Bank in good faith under
a Letter of Credit against presentation of a draft or other document that does
not comply with the terms of such Letter of Credit, or (iv) any other event or
circumstance whatsoever, whether or not similar to any of the foregoing, that
might, but for the provisions of this Section, constitute a legal or equitable
discharge of, or provide a right of setoff against, an Applicant's obligations
hereunder. Neither the Issuing Bank, nor any of its Related Parties, shall have
any liability or responsibility by reason of or in connection with the issuance
or transfer of any Letter of Credit or any payment or failure to make any
payment thereunder (irrespective of any of the circumstances referred to in the
preceding sentence), or any error, omission, interruption, loss or delay in
transmission or delivery of any draft, notice or other communication under or
relating to any Letter of Credit (including any document required to make a
drawing thereunder), any error in interpretation of technical terms or any
consequence arising from causes beyond the control of the Issuing Bank; provided
that the foregoing shall not be construed to excuse the Issuing Bank from
liability to the Applicants to the extent of any direct damages (as opposed to
consequential damages, claims in respect of which are hereby waived by the
Applicants to the extent permitted by applicable law) suffered by the Applicants
that are caused by the Issuing Bank's failure to exercise care when determining
whether drafts and other documents presented under a Letter of Credit comply
with the terms thereof. The parties hereto expressly agree that, in the absence
of gross negligence or wilful misconduct on the part of the Issuing Bank (as
finally determined by a court of competent jurisdiction), the Issuing Bank shall
be deemed to have exercised care in each such determination. In furtherance of
the foregoing and without limiting the generality thereof, the parties agree
that, with respect to documents presented which appear on their face to be in
substantial compliance with the terms of a Letter of Credit, the Issuing Bank
may, in its sole discretion, either accept and make payment upon such documents
without responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

      (e) Disbursement Procedures. The Issuing Bank shall, promptly following
its receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit. The Issuing Bank shall promptly notify the
relevant Applicant by telephone (confirmed by telecopy) of such demand for
payment and whether the Issuing Bank has made or will make an LC Disbursement
thereunder; provided that any failure to give or delay in giving such notice
shall not relieve such Applicant of its obligation to reimburse the Issuing Bank
with respect to any such LC Disbursement.

      (g) Interim Interest. If the Issuing Bank shall make any LC Disbursement,
then, unless the relevant Applicant shall reimburse such LC Disbursement in full
on the date such LC Disbursement is made, the unpaid amount thereof shall bear
interest, for each day from and including the date such LC Disbursement is made
to but excluding the date that such Applicant reimburses such LC Disbursement,
at the Alternative Base Rate; provided that, if such Applicant fails to
reimburse such LC Disbursement when due pursuant to paragraph (c) of this
Section, then Section 2.05 shall apply.


                                       6

      (h) Cash Collateralization. If any Event of Default shall occur and be
continuing, then on or prior to the Business Day following the Business Day on
which the Applicants receive notice from the Issuing Bank demanding the deposit
of cash collateral pursuant to this paragraph, the Applicants shall deposit in
an account with the Issuing Bank an amount in cash equal to the LC Exposure as
of such date plus any accrued and unpaid interest thereon; provided that the
obligation to deposit such cash collateral shall become effective immediately,
and such deposit shall become immediately due and payable, without demand or
other notice of any kind, upon the occurrence of any Event of Default with
respect to the Applicants described in clause (e) of Article VI. Such deposit
shall be held by the Issuing Bank as collateral for the payment and performance
of the obligations of the Applicants under this Agreement. The Issuing Bank
shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account. Other than any interest earned on the investment
of such deposits, which investments shall be made at the option and sole
discretion of the Issuing Bank and at the Applicants' risk and expense, such
deposits shall not bear interest. Interest or profits, if any, on such
investments shall accumulate in such account. Moneys in such account shall be
applied by the Issuing Bank to reimburse the Issuing Bank for LC Disbursements
for which it has not been reimbursed and, to the extent not so applied, shall be
held for the satisfaction of the reimbursement obligations of the Applicants for
the LC Exposure at such time. If the Applicants are required to provide an
amount of cash collateral hereunder as a result of the occurrence of an Event of
Default, such amount, including interest or any profits thereon, if any, (to the
extent not applied as aforesaid) shall be returned to the Applicants within
three Business Days after all Events of Default have been cured or waived.

      SECTION 2.03. Termination and Reduction of Commitment. (a) Unless
previously terminated, the Commitment shall terminate on the Commitment
Termination Date.

      (b) The Applicants may at any time terminate, or from time to time reduce,
the Commitment; provided that (i) each reduction of the Commitment shall be in
an amount that is an integral multiple of $1,000,000 and not less than
$10,000,000 and (ii) the Applicants shall not terminate or reduce the Commitment
if the sum of the LC Exposure would exceed the Commitment.

      (c) The Applicants shall notify the Issuing Bank of any election to
terminate or reduce the Commitment under paragraph (b) of this Section at least
two Business Days prior to the effective date of such termination or reduction,
specifying such election and the effective date thereof.

      SECTION 2.04. Fees. (a) The Applicants jointly and severally agree to pay
to the Issuing Bank a facility fee, which shall accrue at a rate per annum equal
to 0.07% on the daily amount of the Commitment (used or unused) of the Issuing
Bank during the period from and including the Effective Date to but excluding
the date on which the Commitment terminates. Accrued facility fees shall be
payable in arrears on the last day of March, June, September and December of
each year and on the date on which the Commitment terminates, commencing on the
first such date to occur after the date hereof. All commitment fees shall be
computed on the basis of a year of 360 days and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

      (b) Each Applicant agrees to pay to the Issuing Bank a commission with
respect to each Letter of Credit issued for its account, which shall accrue at
the a rate per annum equal to 0.35% on the average daily amount of the Issuing
Bank's LC Exposure (excluding any portion thereof attributable to unreimbursed
LC Disbursements) during the period from and including the Effective Date to but
excluding the later of the date on which the Commitment terminates and the date
on which the Issuing Bank ceases to have any LC Exposure, as well as the Issuing
Bank's standard reasonable fees with respect to the issuance, amendment, renewal
or extension of any Letter of Credit or processing of


                                       7
<PAGE>

drawings thereunder. Commissions accrued through and including the last day of
March, June, September and December of each year shall be payable on the third
Business Day following such last day, commencing on the first such date to occur
after the Effective Date; provided that all such fees shall be payable on the
date on which the Commitment terminates and any such fees accruing after the
date on which the Commitment terminates shall be payable on demand. Any other
fees payable to the Issuing Bank pursuant to this paragraph shall be payable
within 10 Business Days after demand. Commissions shall be computed on the basis
of a year of 360 days and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day).

      (c) All fees payable hereunder shall be paid on the dates due, in
immediately available funds. Fees paid shall not be refundable under any
circumstances.

      SECTION 2.05. Interest. If any principal of or interest on any LC
Disbursement or any fee or other amount payable by the Applicants hereunder is
not paid when due, whether at stated maturity, upon acceleration or otherwise,
such overdue amount shall bear interest, after as well as before judgment, at a
rate per annum equal to 2% plus the Alternative Base Rate and be payable upon
demand. All interest hereunder shall be computed on the basis of a year of 360
days, except that interest computed by reference to the Alternate Base Rate at
times when the Alternate Base Rate is based on the Prime Rate shall be computed
on the basis of a year of 365 days (or 366 days in a leap year), and in each
case shall be payable for the actual number of days elapsed (including the first
day but excluding the last day).

      SECTION 2.06. Increased Costs. (a) If any Change in Law shall impose,
modify or deem applicable any reserve, special deposit or similar requirement
against assets of, deposits with or for the account of, or credit extended by
the Issuing Bank, and the result of any of the foregoing shall be to increase
the cost to the Issuing Bank of issuing or maintaining any Letter of Credit or
to reduce the amount of any sum received or receivable by the Issuing Bank
hereunder (whether of principal, interest or otherwise), then the Applicants
jointly and severally agree to pay to the Issuing Bank on demand such additional
amount or amounts as will compensate the Issuing Bank, as the case may be, for
such additional costs incurred or reduction suffered.

      (b) If the Issuing Bank determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on the Issuing Bank's capital or on the capital of the Issuing Bank's holding
company, if any, as a consequence of this Agreement, or the Letters of Credit
issued by the Issuing Bank, to a level below that which the Issuing Bank or the
Issuing Bank's holding company could have achieved but for such Change in Law
(taking into consideration the Issuing Bank's policies and the policies of the
Issuing Bank's holding company with respect to capital adequacy), then from time
to time the Applicants jointly and severally agree to pay to the Issuing Bank on
demand such additional amount or amounts as will compensate the Issuing Bank or
the Issuing Bank's holding company for any such reduction suffered.

      (c) A certificate of the Issuing Bank setting forth the amount or amounts
determined in good faith as necessary to compensate the Issuing Bank or its
holding company, as specified in paragraph (a) or (b) of this Section, and
containing a reasonable description of the facts and circumstances regarding the
demand shall be delivered to the Applicants and shall be conclusive absent
manifest error. The Applicants shall pay the Issuing Bank the amount shown as
due on any such certificate within 10 days after receipt thereof.

      (d) Failure or delay on the part of the Issuing Bank to demand
compensation pursuant to this Section shall not constitute a waiver of the
Issuing Bank's right to demand such compensation; provided


                                       8
<PAGE>

that the Applicants shall not be required to compensate the Issuing Bank
pursuant to this Section for any increased costs or reductions incurred more
than 270 days prior to the date that the Issuing Bank notifies the Applicants of
the Change in Law giving rise to such increased costs or reductions and of the
Issuing Bank's intention to claim compensation therefor; provided further that,
if the Change in Law giving rise to such increased costs or reductions is
retroactive, then the 270-day period referred to above shall be extended to
include the period of retroactive effect thereof.

      SECTION 2.07. Taxes. (a) Subject to the immediately succeeding sentence,
any and all payments by or on account of any obligation of any Applicant
hereunder shall be made free and clear of and without deduction for any
Indemnified Taxes or Other Taxes imposed by Bermuda or any other jurisdiction in
which such Applicant conducts its business; provided that if such Applicant
shall be required to deduct any Indemnified Taxes or Other Taxes from such
payments, then (i) the sum payable shall be increased as necessary so that after
making all required deductions (including deductions applicable to additional
sums payable under this Section) the Issuing Bank receives an amount equal to
the sum it would have received had no such deductions been made, (ii) such
Applicant shall make such deductions and (iii) such Applicant shall pay the full
amount deducted to the relevant Official Body in accordance with applicable law.
No additional sums will be payable pursuant to the immediately preceding
sentence by an Applicant hereunder to the Issuing Bank with respect to any
Indemnified Tax or Other Tax which would not have been imposed, payable or due:
(i) but for the existence of any present or former connection between the
Issuing Bank and Bermuda or any other jurisdiction in which such Applicant
conducts its business (including, without limitation, the Issuing Bank being or
having or maintaining or having maintained a permanent establishment or being or
having been engaged in business in, Bermuda or any other jurisdiction in which
such Applicant conducts its business); or (ii) but for the failure of the
Issuing Bank to promptly comply with a request by the Applicant to satisfy any
certification, identification or other reporting requirements, whether imposed
by statute, treaty, regulation or administrative practices, concerning
nationality, residence or connection with any applicable taxing jurisdiction.
The obligation to pay additional sums in respect of Indemnified Taxes or Other
Taxes shall not apply to any Tax which is payable otherwise than by deduction or
withholding.

      (b) If the Issuing Bank determines in its sole discretion in good faith
that it has received a refund in respect of any Indemnified Taxes as to which it
has been idemnified by an Applicant, or with respect to which an Applicant has
paid additional amounts pursuant to this Section 2.07, the Issuing Bank shall
promptly after the date of such receipt pay over the amount of such refund to
such Applicant (but only to the extent of indemnity payments made, or additional
amounts paid, by such Applicant under this Section 2.07 with respect to
Indemnified Taxes giving rise to such refund and only to the extent that the
Issuing 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 Issuing Bank (including additional Indemnified Taxes
attributable to such refund, as determined by the Issuing Bank) and without
interest (other than interest, if any, paid by the relevant Official Body with
respect to such refund). An Applicant receiving any such payment from the
Issuing Bank shall, upon demand, pay to the Issuing Bank any amount paid over to
such Applicant by the Issuing Bank (plus penalties, interest or other charges)
in the event the Issuing Bank is required to repay any portion of such refund to
such Official Body. Nothing in the Section 2.07 shall entitle an Applicant to
have access to the records of the Issuing Bank including, without limitation,
tax returns.

      (c) In addition, each Applicant shall pay any Other Taxes to the relevant
Official Body in accordance with applicable law.

      (d) Each Applicant shall indemnify the Issuing Bank, promptly after
receipt of written demand


                                       9
<PAGE>

therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by
the Issuing Bank on to the relevant Official Body in accordance with applicable
law or with respect to any payment by or on account of any obligation of such
Applicant hereunder (including Indemnified Taxes or Other Taxes imposed or
asserted on or attributable to amounts payable under this Section 2.07) and any
penalties and interest arising therefrom or with respect thereto, whether or not
such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Official Body. A certificate as to the amount of such
payment or liability delivered to an Applicant by the Issuing Bank shall be
conclusive absent manifest error.

      (e) As soon as practicable after any payment of Indemnified Taxes or Other
Taxes by an Applicant or by the Issuing Bank, as the case may be, to an Official
Body, such Applicant or Issuing Bank shall deliver to the other party hereto the
original or a certified copy of a receipt issued by such Official Body
evidencing such payment, a copy of the return reporting such payment or other
reasonable evidence of such payment.

      SECTION 2.08. Payments Generally. (a) The Applicants shall make each
payment required to be made by them hereunder prior to 12:00 noon, New York City
time, on the date when due, in immediately available funds, without set-off or
counterclaim. Any amounts received after such time on any date may, in the
discretion of the Issuing Bank, be deemed to have been received on the next
succeeding Business Day for purposes of calculating interest thereon. All such
payments shall be made to the Issuing Bank at its offices at 270 Park Avenue,
New York, New York 10017. If any payment hereunder shall be due on a day that is
not a Business Day, the date for payment shall be extended to the next
succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
hereunder shall be made in dollars.

      (b) If at any time insufficient funds are received by and available to the
Issuing Bank to pay fully all amounts of unreimbursed LC Disbursements, interest
and fees then due hereunder, such funds shall be applied (i) first, towards
payment of interest and fees then due hereunder and (ii) second, towards payment
of unreimbursed LC Disbursements then due hereunder.

                                   ARTICLE III

therein, or any amendment of, or consent to any deviation from or other

issue, amend, renew or extend any Letter of Credit, is subject to the

                                Events of Default

such failure shall continue after the applicable grace period, if any, specified
in the agreement or instrument relating to such borrowed money obligations or
the Existing Revolver or such Revolving Credit Agreement; or any other event
shall occur or condition shall exist under an agreement or instrument relating
to any obligation for borrowed money in the principal amount of $10,000,000 or
more or contained in the Existing Revolver or such Revolving Credit Agreement
and shall continue after the applicable grace period, if any, specified in such
agreement or instrument, the Existing Revolver or such Revolving Credit

permit the acceleration of, the scheduled maturity of any such obligations; or
any such obligations shall be declared due and payable, or required to be
prepaid (other than by scheduled required prepayment), prior to the stated
maturity thereof;

      (f) any Applicant shall admit in writing its inability to pay its debts
generally as they become due, or shall make a general assignment for the benefit

any such proceeding instituted against any Applicant (but not instituted by any
Applicant), either such proceeding shall remain undismissed or unstayed for a
period of 60 days, or any of the actions sought in such proceeding (including,

continuance of such event, the Issuing Bank may by notice to the Applicants,
take either or both of the following actions, at the same or different times:

                                   ARTICLE VII

                                  Miscellaneous

      SECTION 7.01. Notices. Except in the case of notices and other
communications expressly permitted to be given by telephone, all notices and
other communications provided for herein shall be in writing and shall be
delivered by hand or overnight courier service, mailed by certified or
registered mail or sent by telecopy, as follows:

      (a) if to XL Insurance, to it at Cumberland House, One Victoria Street,
      P.O. Box HM 2245, Hamilton, HMJX Bermuda, Attention of William Robbie
      (Telecopy No. (441) 292-8618, with a copy to Paul Giordano, Esq. at the
      same address and telecopy number);

      (b) if to XL Mid Ocean, to it at Cumberland House, One Victoria Street,
P.O. Box HM 2245, Hamilton, HMJX Bermuda, Attention of William Robbie (Telecopy
No. (441) 292-8618, with a copy to Paul Giordano, Esq. at the same address and
telecopy number);

      (b) if to the Issuing Bank, to The Chase Manhattan Bank, 270 Park Avenue,
New York, New York 10017, Attention of Donald Rands (Telephone No. (212)
270-5528; Telecopy No. (212) 270-1001), with a copy to Daniel Serrao, Chase
Securities Inc. 270 Park Avenue, New York, New York 10017 (Telephone No. (212)

Any party hereto may change its address or telecopy number for notices and other
communications hereunder by notice to the other parties hereto. All notices and
other communications given to any party hereto in accordance with the provisions
of this Agreement shall be deemed to have been given on the date of receipt.

      SECTION 7.02. Waivers; Amendments. (a) No failure or delay by the Issuing
Bank in exercising any right or power hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such right or power, or
any abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Issuing Bank hereunder are
cumulative and are not exclusive of any rights or remedies that it would
otherwise have. No waiver of any provision of this Agreement or consent to any
departure by the Applicants therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) of this Section, and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given. Without limiting the generality of the foregoing, the issuance
of a Letter of Credit shall not be construed as a waiver of any Default,
regardless of whether the Issuing Bank may have had notice or knowledge of such
Default at the time.

      (b) Neither this Agreement nor any provision hereof may be waived, amended
or modified except pursuant to an agreement or agreements in writing entered
into by the Applicants and the Issuing Bank.

      SECTION 7.03. Expenses; Indemnity; Damage Waiver. (a) The Applicants
jointly and severally agree to pay (i) all reasonable out-of-pocket expenses
incurred by the Issuing Bank and its


                                       14
<PAGE>

Affiliates, including the reasonable fees (or internal cost allocations, in the
case of internal legal counsel for the Issuing Bank), charges and disbursements
of counsel for the Issuing Bank, in connection with the preparation and
administration of this Agreement or any amendments, modifications or waivers of
the provisions hereof (whether or not the transactions contemplated hereby or
thereby shall be consummated), (ii) all reasonable out-of-pocket expenses
incurred by the Issuing Bank in connection with the issuance, amendment, renewal
or extension of any Letter of Credit or any demand for payment thereunder and
(iii) all reasonable out-of-pocket expenses incurred by the Issuing Bank,
including the reasonable fees, charges and disbursements of any counsel for the
Issuing Bank in connection with the enforcement or protection of its rights in
connection with this Agreement, including its rights under this Section, or in
connection with the Letters of Credit issued hereunder, including all such
reasonable out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Letters of Credit.

      (b) The Applicants jointly and severally agree to indemnify the Issuing
Bank and each Related Party of the Issuing Bank (each such Person being called
an "Indemnitee") against, and hold each Indemnitee harmless from, any and all
losses, claims, damages, liabilities and related expenses, including the
reasonable fees, charges and disbursements of any counsel for any Indemnitee,
incurred by or asserted against any Indemnitee arising out of, in connection
with, or as a result of (i) the execution or delivery of this Agreement or any
agreement or instrument contemplated hereby, the performance by the parties
hereto of their respective obligations hereunder or the consummation of the
Transactions or any other transactions contemplated hereby, (ii) any Letter of
Credit or the use of the proceeds therefrom (including any refusal by the
Issuing Bank to honor a demand for payment under a Letter of Credit if the
documents presented in connection with such demand do not strictly comply with
the terms of such Letter of Credit), or (iii) any actual or prospective claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether based on contract, tort or any other theory and regardless of whether
any Indemnitee is a party thereto; provided that such indemnity shall not, as to
any Indemnitee, be available to the extent that such losses, claims, damages,
liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the gross
negligence or wilful misconduct of such Indemnitee.

      (c) To the extent permitted by applicable law, the Applicants shall not
assert, and hereby waive, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions, any Letter of Credit or the use of the proceeds thereof.

      (d) All amounts due under this Section shall be payable promptly after
written demand therefor.

      SECTION 7.04. Successors and Assigns. (a) The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns permitted hereby (including any Affiliate of
the Issuing Bank that issues any Letter of Credit), except that no Applicant may
assign or otherwise transfer any of its rights or obligations hereunder without
the prior written consent of the Issuing Bank (and any attempted assignment or
transfer by such Applicant without such consent shall be null and void). Nothing
in this Agreement, expressed or implied, shall be construed to confer upon any
Person (other than the parties hereto, their respective successors and assigns
permitted hereby (including any Affiliate of the Issuing Bank that issues any
Letter of Credit) and, to the extent expressly contemplated hereby, the Related
Parties of the Issuing Bank) any legal or equitable right, remedy or claim under
or by reason of this Agreement.


                                       15

      (b) The Issuing Bank may, in the ordinary course of its commercial banking
business and in accordance with applicable law, assign to one or more assignees
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitment or LC Exposure); provided that, except in the
case of an assignment to an Affiliate of the Issuing Bank, the Applicants must
give their prior written consents to such assignment (which consents shall not
be unreasonably withheld).

      (c) The Issuing Bank may, in the ordinary course of its commercial banking
business and in accordance with applicable law, without the consent of the
Applicants, sell participations to one or more banks or other entities (a
"Participant") in all or a portion of the Issuing Bank's rights and obligations
under this Agreement (including all or a portion of its Commitment and the LC
Exposure owing to it); provided that (i) the Issuing Bank's obligations under
this Agreement shall remain unchanged, (ii) the Issuing Bank shall remain solely
responsible to the Applicants for the performance of such obligations and (iii)
the Applicants shall continue to deal solely and directly with the Issuing Bank
in connection with the Issuing Bank's rights and obligations under this
Agreement. Any agreement or instrument pursuant to which the Issuing Bank sells
such a participation shall provide that the Issuing 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 the Issuing Bank will not, without the consent of
the Participant, agree to any amendment, modification or waiver described in the
first proviso to Section 7.02(b) that affects such Participant. Subject to
paragraph (d) of this Section, the Applicants agree that each Participant shall
be entitled to the benefits of Sections 2.06 and 2.07 to the same extent as if
it were the Issuing Bank 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 7.08 as though it were the
Issuing Bank.

      (d) A Participant shall not be entitled to receive any greater payment
under Section 2.06 or 2.07 than the Issuing 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 Applicants' prior
written consents.

      (e) The Issuing Bank may at any time pledge or assign a security interest
in all or any portion of its rights under this Agreement to secure obligations
of the Issuing Bank, including any pledge or assignment to secure obligations to
a Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of
a security interest shall release the Issuing Bank from any of its obligations
hereunder or substitute any such pledgee or assignee for the Issuing Bank as a
party hereto.

      SECTION 7.05. Survival. All covenants, agreements, representations and
warranties made by the Applicants herein and in the certificates or other
instruments delivered in connection with or pursuant to this Agreement shall be
considered to have been relied upon by the Issuing Bank and shall survive the
execution and delivery of this Agreement and the issuance of any Letters of
Credit, and shall continue in full force and effect as long as any amount
payable under this Agreement is outstanding and unpaid or any Letter of Credit
is outstanding and so long as the Commitment has not expired or terminated. The
provisions of Sections 2.06 and Article VII shall survive and remain in full
force and effect regardless of the consummation of the transactions contemplated
hereby, the expiration or termination of the Letters of Credit and the
Commitment or the termination of this Agreement or any provision hereof.


                                       16

      SECTION 7.06. Counterparts; Integration; Effectiveness. This Agreement may
be executed in counterparts (and by different parties hereto on different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement constitutes
the entire contract among the parties relating to the subject matter hereof and
supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof. Except as provided in Section 4.01, this
Agreement shall become effective when it shall have been executed by the Issuing
Bank and when the Issuing Bank shall have received counterparts hereof which,
when taken together, bear the signature of the Applicants, and thereafter shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns. Delivery of an executed counterpart of a
signature page of this Agreement by telecopy shall be effective as delivery of a
manually executed counterpart of this Agreement.

      SECTION 7.07. Severability. Any provision of this Agreement held to be
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without affecting the validity, legality and enforceability of
the remaining provisions hereof; and the invalidity of a particular provision in
a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

      SECTION 7.08. Right of Setoff. If an Event of Default shall have occurred
and be continuing, the Issuing Bank and each of its Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other obligations at any time
owing by the Issuing Bank or such Affiliate to or for the credit or the account
of any Applicant against any of and all the obligations of such Applicant now or
hereafter existing under this Agreement held by the Issuing Bank, irrespective
of whether or not the Issuing Bank shall have made any demand under this
Agreement and although such obligations may be unmatured. The rights of the
Issuing Bank under this Section are in addition to other rights and remedies
(including other rights of setoff) which the Issuing Bank may have.

      SECTION 7.09. Governing Law; Jurisdiction; Consent to Service of Process.
(a) This Agreement shall be construed in accordance with and governed by the law
of the State of New York.

      (b) Each Applicant hereby irrevocably and unconditionally submits, for
itself and its property, to the nonexclusive jurisdiction of the Supreme Court
of the State of New York sitting in New York County and of the United States
District Court of the Southern District of New York, and any appellate court
from any thereof, in any action or proceeding arising out of or relating to this
Agreement, or for recognition or enforcement of any judgment, and each of the
parties hereto hereby irrevocably and unconditionally agrees that all claims in
respect of any such action or proceeding may be heard and determined in such New
York State or, to the extent permitted by law, in such Federal court. Each of
the parties hereto agrees that a final judgment in any such action or proceeding
shall be conclusive and may be enforced in other jurisdictions by suit on the
judgment or in any other manner provided by law. Nothing in this Agreement shall
affect any right that the Issuing Bank may otherwise have to bring any action or
proceeding relating to this Agreement against any Applicant or its properties in
the courts of any jurisdiction.

      (c) Each Applicant hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement in any court referred to in
paragraph (b) of this Section. Each of the parties hereto hereby irrevocably
waives, to the fullest extent


                                       17
<PAGE>

permitted by law, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any such court.

      (d) Each Applicant irrevocably consents to service of process in the
manner provided for notices in Section 7.01. Nothing in this Agreement will
affect the right of any party to this Agreement to serve process in any other
manner permitted by law.

      SECTION 7.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL
BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER
BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES
THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

      SECTION 7.11. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and shall not affect the construction of, or be taken into
consideration in interpreting, this Agreement.

      SECTION 7.12. Confidentiality. The Issuing Bank agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its and its Affiliates' directors, officers, employees
and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such disclosure is made will be informed of
the confidential nature of such Information and instructed to keep such
Information confidential), (b) to the extent requested by any regulatory
authority, (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process, (d) to any other party to this Agreement,
(e) in connection with the exercise of any remedies hereunder or any suit,
action or proceeding relating to this Agreement or the enforcement of rights
hereunder, (f) subject to an agreement containing provisions substantially the
same as those of this Section, to any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations
under this Agreement, (g) with the consent of the Applicant or (h) to the extent
such Information (i) becomes publicly available other than as a result of a
breach of this Section or (ii) becomes available to the Issuing Bank on a
nonconfidential basis from a source other than an Applicant. For the purposes of
this Section, "Information" means all information received from any Applicant
relating to such Applicant or its business, other than any such information that
is available to the Issuing Bank on a nonconfidential basis prior to disclosure
by such Applicant; provided that, in the case of information received from such
Applicant after the date hereof, such information is clearly identified at the
time of delivery as confidential. Any Person required to maintain the
confidentiality of


                                       18
<PAGE>

Information as provided in this Section shall be considered to have complied
with its obligation to do so if such Person has exercised the same degree of
care to maintain the confidentiality of such Information as such Person would
accord to its own confidential information.

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

      basis points per annum on the maximum amount of the Bank's liability under
      the Letter of Credit.

5. The Account Parties liabilities in relation to Letters of Credit

5.1 Reimbursement

      Each relevant Account Party shall:

      (a)   pay to the Bank on demand an amount equal to and in the same

            any Letter of Credit issued pursuant to this Facility with any sums
            payable by the Account Party hereunder); and

      (b)   indemnify the Bank on demand against all actions, charges, claims,
            costs, damages, demands, expenses, taxes, duties, losses and
            proceedings (other than actions, charges, claims, costs, damages,
            demands, taxes, duties, losses and proceedings resulting from
            negligence or wilful default on the part of the Bank) which may be
            brought or preferred against the Bank or which the Bank may suffer
            or incur arising out of or in connection with any Letter of Credit
            issued hereunder or any amendment or variation in the terms of that
            Letter of Credit in connection with the enforcement or the
            preservation of the Bank's rights hereunder.

5.2 Authorisations

      The Bank is irrevocably authorised to make any payments and comply with
      any demands which may be claimed from or made upon the Bank under, in
      connection with or by reason of any Letter of Credit issued pursuant to
      the terms hereof on the first demand being made. The Bank may make these
      demands or comply with these payments:

      (a)   without any reference to or further authority from the relevant
            Account Party;

      (b)   without requiring proof that the amounts so demanded are or were
            due; and

      (c)   notwithstanding that an Account Party may dispute the validity of
            demand or payment or that any demand is made after the stated expiry
            date (if any) of the relevant Letter of Credit.

5.3 Binding effect of payments

      Any payment which the Bank shall make in accordance with (or which is
      apparently or purporting to be in accordance with) any Letter of Credit
      issued hereunder shall be binding upon, and shall be accepted by, the
      Company as conclusive evidence that the Bank was liable to make such
      payment.


                                       3
<PAGE>

5.4 Defences

      It shall not be a defence to a claim by the Bank against an Account Party
      hereunder that the Bank could have resisted any claim by the beneficiary
      of the relevant Letter of Credit.

5.5 Risk

      Any Letter of Credit issued hereunder or any communication shall be sent
      at the relevant Account Party's risk and cost and each Account Party shall
      hold the Bank harmless from any liability (other than liability resulting
      from negligence or wilful default on the part of the Bank) for any loss or
      damage arising out of any delay, loss in transit, errors in translation,
      coding or decoding or omissions, variations, mutilations or other errors
      in transmission of those letters, facsimile, cables or telex messages.

6. Default Interest

      (a)   If an Account Party fails to pay any amount payable by it hereunder
            on the due date thereof, the Account Party shall on demand from time
            to time pay interest on such overdue amount from the due date up to
            the date of receipt of actual payment (both before and after
            judgement) at a rate determined by the Bank from time to time to be
            2 % above the offered rate quoted by leading banks in the London
            Interbank Market at or about 11.00 a.m. (London time) on the
            appropriate quotation date for deposits of a similar amount to, and
            in the currency of, the unpaid amount, and for such interest period
            as the Bank may consider appropriate. Such interest shall be
            compounded daily.

      (b)   Interest shall be calculated on the basis of a 360 day year and for
            the actual number of days elapsed in the period of question.

7. Payments

      All payments to be made by an Account Party hereunder shall be made to the
      Bank in US Dollar funds for value on the due date to Chase Manhattan Bank
      N.A. New York, for the account of ING Bank N.V. London Branch, Account
      No.001-1-938123 or in other currencies to an account as instructed by the
      Bank, without set-off or counter-claim and free of and without deduction
      for any taxes, levies, withholdings or imposts imposed by any governmental
      or taxing authority in Bermuda or the Cayman Islands whatsoever. If any
      deductions whatsoever are required to be made, each Account Party hereby
      agrees to indemnify the Bank against the same and will pay such additional
      amounts as the Bank may certify as necessary to ensure receipt by the Bank
      of the full amount it would have received hereunder but for such
      deduction. In the event of such payment the Account Parties will deliver
      promptly to the Bank such tax receipts or other documentation as it may
      reasonably require. No such additional amounts will be payable with
      respect to a payment made to the Bank with respect to any tax or other
      amount which would not have been imposed, payable or due: (i) but for the
      existence for any present or former connection between the Bank and
      Bermuda or the Cayman Islands (including without limitation, the Bank
      being or having or maintaining or having maintained a permanent
      establishment or being or having been engaged in business in, Bermuda or
      the Cayman Islands); or (ii) but for the failure to comply with a request
      by an Account Party to


                                       4
<PAGE>

      satisfy any certification, identification or other reporting requirements,
      whether imposed by statute, treaty, regulation or administrative
      practices, concerning nationality, residence or connection with any
      applicable taxing jurisdiction. The obligation to pay additional amounts
      in respect of taxes shall not apply to any tax which is payable otherwise
      than by deduction or withholding.

8. Increased Costs

      If the result of any present or future law, regulation, treaty or official
      directive (whether or not having the force of law) or any change therein
      or in the interpretation or application thereof or compliance by the Bank
      with any request of any relevant authority is directly or indirectly to
      increase the cost to the Bank of the transactions contemplated hereby, or
      is to reduce any amount receivable by the Bank or the effective return to
      the Bank hereunder whether by way of change in the manner in which the
      Bank allocates capital to the Account Parties' obligations hereunder or
      otherwise, each Account Party will, forthwith on demand, which demand
      shall include a description of the facts and circumstances regarding such
      a demand, pay to the Bank such amounts as the Bank shall certify as
      necessary to compensate it for such additional cost or reduction.

9. Collateralisation or cancellation of Letters of Credit issued to The Council
   of Lloyd's

      and an Account Party may serve notice on the Bank, at least thirty days
      before each anniversary of the date of issuance of a Letter of Credit (an
      "Anniversary Date") issued in favour of The Council of Lloyd's, that the
      Bank or the Account Party, respectively, does not wish to extend such
      Letter of Credit beyond its Expiry Date. On receipt of such notice by the
      relevant Account Party or on service of such notice by the relevant
      Account Party on the Bank, the Account Party undertakes to either (i)
      provide the Bank on or before the Anniversary Date with collateral equal
      to 110% of the face value of such Letters of Credit in the form of AA
      rated Corporate Bonds or OECD bonds together with a charge or other
      security over such collateral in a form satisfactory to the Bank or (ii)
      to ensure that the Letter of Credit is cancelled on or before the
      Anniversary Date. Failure by an Account Party to comply with this clause 9
      shall constitute an Event of Default in accordance with clause 12 hereof.
