NOTE ON FORWARD-LOOKING STATEMENTS
 
  This report contains certain forward-looking statements within the meaning
of Section 27A of the United States Securities Act of 1933, as amended, and
Section 21E of the United States Securities Exchange Act of 1934, as amended.
Forward-looking statements are statements other than historical information or
statements of current condition. Some forward-looking statements may be
identified by use of terms such as "believes", "anticipates", "intends", or
"expects". These statements relate to the plans of the Company for future
operations, including the dividend policy pursuant to which the Company
intends to distribute as dividends to holders of common shares of the Company
("Common Shares") and exchangeable non-voting shares of LaSalle Re
("Exchangeable Non-Voting Shares") in each fiscal year 50% to 60% of the
amount by which its net income (before minority interest) from the prior
fiscal year exceeds the amount of dividends payable on preferred shares of the
Company in the current fiscal year. In light of the risks and uncertainties
inherent in all future projections, these statements should not be regarded as
a representation that the objectives will be achieved. Many factors could
cause actual results to differ materially from those in the forward-looking
statements, including, but not limited, to the following: catastrophic events
of unanticipated frequency or severity; changes in the demand for or supply of
property catastrophe reinsurance; actions of competitors; changes in the
Company's financial ratings; changes in insurance or tax laws or regulations
or governmental interpretations thereof; changes in foreign economic
conditions including fluctuations in currency rates or global markets; a major
decrease in the cession of business from CNA Financial Corporation ("CNA");
any failure of the Company's computer systems or the computer systems of third
parties that are material to the Company's operations (such as the computer
systems of service providers, suppliers and brokers) to process correctly
information relating to dates in and after the year 2000. The Company
undertakes no obligation to release publicly the results of any future
revisions it may make to forward-looking statements to reflect events or
circumstances after the date hereof or to reflect the occurrence of
unanticipated events.
 
ITEM 1. BUSINESS
 
GENERAL DEVELOPMENT OF THE BUSINESS
 
  The Company is a property and casualty reinsurer writing worldwide
specialist products with an emphasis on catastrophe cover. Catastrophe
reinsurance contracts cover unpredictable events such as hurricanes,
windstorms, hailstorms, earthquakes, fires, industrial explosions, freezes,
riots, floods and other man-made or natural disasters. The Company also seeks
to take advantage of pricing opportunities that may occur in other lines of
reinsurance. These lines currently include property risk excess, property pro
rata treaty, casualty clash, marine, crop hail, aviation, satellite, terrorism
and political risk coverages.
 
  LaSalle Re was incorporated in Bermuda in October 1993 with an initial
capitalization of $373.1 million from institutional and other investors (the
"Founding Shareholders"). It commenced operations on November 22, 1993.
LaSalle Re Holdings Limited was incorporated in Bermuda in September 1995 to
act as an investment holding company for LaSalle Re.
 
  LaSalle Re has two wholly owned subsidiaries, LaSalle Re Services, which
acts as a representative office for the Company in the United Kingdom, and
LaSalle Re Capital, which was incorporated in Bermuda in November 1996 to
provide capital support to selected syndicates at Lloyd's. LaSalle Re Capital
was accepted as a corporate member ("Corporate Member") of Lloyd's in December
1996 and, with effect from January 1, 1997, has participated in three Lloyd's
syndicates. In November 1995, the Company and LaSalle Re consummated an offer
(the "Exchange Offer") pursuant to which, among other things, the Founding
Shareholders exchanged their capital stock in LaSalle Re for Common Shares of
the Company and, in certain circumstances, Exchangeable
 
                                     10K-2
<PAGE>
 
Non-Voting Shares of LaSalle Re. The Exchangeable Non-Voting Shares are held
by certain Founding Shareholders who would otherwise hold, or cause another
shareholder to hold, directly, indirectly or constructively, in excess of 9.9%
of the voting power of the Company or LaSalle Re. The Exchangeable Non-Voting
Shares are exchangeable, at the option of the holder, for Common Shares on a
one-for-one basis, unless the board of directors of the Company (the "Board")
determines such exchange may cause actual or potential adverse tax
consequences to the Company or any shareholder. The Exchangeable Non-Voting
Shares will at all times rank as to assets, dividends and in all other
respects on a parity with the common shares of LaSalle Re, except that they do
not have the right to vote on any matters except as required by Bermuda law
and in connection with certain actions by the Company. The holders of the
Exchangeable Non-Voting Shares constitute the minority holding in LaSalle Re.
 
  In November 1995, the Company and certain Founding Shareholders also
consummated an initial public offering of 4,312,500 Common Shares (the
"Initial Public Offering"). Of these shares, 2,920,500 were sold by Founding
Shareholders and 1,392,000 by the Company. The proceeds from the sale of the
1,392,000 shares sold by the Company were used to enable LaSalle Re to redeem
shares of its capital stock (the "Redemption"). Upon the consummation of the
Exchange Offer, the Initial Public Offering and the Redemption, the Company
owned 100% of the outstanding voting stock, which constituted 63% of the
outstanding capital stock, of LaSalle Re.
 
  In December 1996, the Company completed a secondary offering of Common
Shares (the "Secondary Offering"). In connection with the Secondary Offering,
certain Founding Shareholders of LaSalle Re exchanged 2,119,110 of their
Exchangeable Non-Voting Shares for Common Shares. As a result of this
exchange, the Company increased its ownership of the outstanding capital stock
of LaSalle Re from 63% to 73%.
 
  In March 1997, the Company issued 3,000,000 Series A Preferred Shares in a
public offering (the "Preferred Offering"). The Series A Preferred Shares, par
value $1.00 per share, carry a liquidation preference of $25.00 per share,
plus accrued and unpaid dividends, if any, to the date of liquidation.
Dividends on the Series A Preferred Shares are payable in an amount per share
equal to 8.75% of the liquidation preference per annum (equivalent to $2.1875
per share). Net proceeds from the Preferred Offering after underwriting
discounts and commissions were $72.6 million.
 
  In May 1997, the Company completed a $100 million tender offer (the "Tender
Offer") whereby it purchased for cancellation 3,703,703 of its Common Shares
at a price of $27.00 per share. The Tender Offer was made to all holders of
Common Shares and Common Share equivalents, which included Exchangeable Non-
Voting Shares and options to purchase Common Shares and Exchangeable Non-
Voting Shares. Pursuant to the Tender Offer, 2,163,538 Exchangeable Non-Voting
Shares were exchanged for Common Shares and 95,679 options for Exchangeable
Non-Voting Shares were exercised and exchanged for Common Shares. As a result
of these exchanges, the Company increased its ownership of the outstanding
capital stock of LaSalle Re from 73% to 79%. The Company has continually owned
100% of the outstanding voting stock of LaSalle Re.
 
  In order to reduce its earnings volatility, protect its capital base and
support its dividend policy, the Company purchased a multi-year excess of loss
reinsurance program. The program first incepted January 1, 1997; however, as
no losses occurred, the contract was canceled and rewritten with the Company
receiving significant return premiums on the 1997 contract. The re-written
program, effective January 1, 1998, secured better terms over the 1997
program, with three event limits and a maximum aggregate recovery of $300
million. The attachment point is triggered by losses incurred directly by the
Company. The program is secured by a company which currently holds a rating of
"A+" (Superior) from A.M. Best Company, Inc. ("A.M. Best") and a claims-paying
rating of "AAA" (Excellent) from Standard & Poor's Ratings Services ("S&P").
See "--Reinsurance Protections Purchased."
 
  Effective July 1, 1997, the Company entered into a $100 million multi-year
Catastrophe Equity Put ("CatEPut") option program. The CatEPut option will
enable the Company to put up to $100 million of equity, through the issue of
convertible preferred shares at pre-negotiated terms, in the event of a major
catastrophe or series of large catastrophes that cause substantial losses to
the Company or its subsidiaries.

  With effect from October 1, 1997, the administrative services agreement
("Administrative Services Agreement"), under which Aon Risk Consultants
(Bermuda) Ltd. ("ARC") provided the Company with actuarial and financial
reporting, accounting, office space and other administrative services, was
terminated. All of the personnel assigned to the Company by ARC became
employees of the Company and services performed by ARC were assumed by the
Company. In connection with the termination of the agreement the Company
agreed to purchase all of the fixed assets owned by ARC and utilized by the
Company for a purchase price of $1.5 million. In addition, the Company agreed
to assume the current leasing agreements.
 
  Effective on October 1, 1998, the underwriting services agreement (the
"Underwriting Services Agreement") under which CNA (Bermuda) Services Limited
("CNA Bermuda") had provided the Company with underwriting services, was
terminated. On that date, all of the personnel assigned to the Company by CNA
Bermuda became employees of the Company and the underwriting function formerly
performed by CNA Bermuda was assumed by the Company directly. In connection
with the termination of the Underwriting Services Agreement, the Company
entered into an underwriting support services agreement (the "Underwriting
Support Services Agreement") with CNA Re Services Company ("CRSC") and CNA
Bermuda. Under the Underwriting Support Services Agreement, CRSC and CNA
Bermuda provide the Company with various support services upon request,
including (i) underwriting personnel to assist the Company's underwriting
staff on a temporary basis, (ii) assistance with actuarial, financial and
statistical analysis and reporting, (iii) support on data processing and other
technical matters, (iv) access to the CNA reinsurance underwriting database
and technology as pertinent to the Company's business, (v) advice on insurance
industry customs and practices and (vi) advice to the Company's human
resources department.

 Property Catastrophe
 
  The largest portion of the Company's business consists of property
catastrophe excess of loss contracts. Property catastrophe excess of loss
reinsurance provides coverage when total losses and loss expenses from a
single occurrence of a covered peril under a portfolio of primary reinsurance
contracts exceed the attachment
 
                                     10K-4
<PAGE>
 
point specified in the reinsurance contract with the primary insurer. Some of
the Company's property catastrophe excess of loss policies limit coverage to
one occurrence in a policy year, but most policies provide for coverage of a
second occurrence after the payment of a reinstatement premium. The Company
also writes a minimal amount of aggregate property catastrophe excess of loss
contracts that cover more than one catastrophe with one attachment point.
 
  The Company writes pro rata of property catastrophe reinsurance treaties
when it believes that rates and volume are attractive. In such programs, the
Company assumes a specified proportion of the exposure under a portfolio of
excess of loss property catastrophe reinsurance contracts written by the
ceding reinsurer and receives an equal proportion of the premium received by
the cedent. The cedent generally receives a ceding commission, based upon the
premiums ceded to the reinsurer, and may also be entitled to receive a profit
commission based on the ratio of losses, loss expenses and the reinsurer's
expenses to premiums ceded. The Company generally requires that its pro rata
of property catastrophe contracts have aggregate exposure limits per
occurrence on a zonal basis. The Company generally obtains detailed
information concerning each underlying contract and the exposures underlying
the risks it assumes and, as appropriate, audits the premiums associated with
the cessions. However, the Company is dependent upon the cedent's
underwriting, pricing and claims administration to yield an underwriting
profit.
 
 Other Lines of Business
 
  The Company formed LaSalle Re Capital to provide capital support on an
underwriting year basis to selected Lloyd's syndicates. The Company has
provided capital support to three syndicates for both the 1997 and 1998
underwriting years of approximately $27.4 million ((Pounds)16.3 million) and
$28.2 million ((Pounds)16.8 million) respectively. Through this support, for
the year ended September 30, 1998, the Company has written gross premiums of
approximately $3.0 million for the 1997 underwriting year and approximately
$18.0 million for the 1998 underwriting year. These syndicates individually
write the following lines of business: direct and facultative property
insurance; marine insurance and reinsurance; and professional indemnity,
directors and officers' insurance and bankers blanket bond business. LaSalle
Re Capital provides capital support to the syndicates through letters of
credit totaling (Pounds)9.8 million ($16.6 million).
 
  The Company's property risk excess of loss contracts cover a cedent's loss
on a single "risk" in excess of the cedent's attachment point, rather than
covering multiple risks as does property catastrophe reinsurance. A "risk" in
this context might mean the insurance coverage on one building or a group of
buildings or the insurance coverage under a single policy, which the reinsured
treats as a single risk. In property pro rata reinsurance treaties, the
Company assumes a proportional part of the original premiums and losses of the
reinsured on non-catastrophe reinsurance contracts. In property pro rata
reinsurance, the reinsurer generally pays the ceding company a ceding
commission. The ceding commission generally is based on the ceding company's
cost of acquiring the business being reinsured (including commissions, premium
taxes, assessments and miscellaneous administrative expenses) and also may
include a profit factor.
 
  In addition to property risk excess of loss and pro rata, the Company also
writes other lines of reinsurance, which currently include casualty, marine,
crop, aviation, satellite and political risk. The Company's underwriting
strategy with respect to these lines of business is to target those classes of
business which demonstrate relatively low historical levels of attritional
loss. Excess of loss contracts are written above a significant attachment
point, such contracts would be expected to respond only to large market losses
such as the destruction of an oil drilling platform (marine coverage) or an
airline disaster (aviation coverage). With proportional contracts, the Company
would expect the results of such contracts to be impacted by large market
losses, along with the cedents expected loss ratio. Claims on these contracts
will arise from physical damage, casualty and major political and trade
crises.
 
  Casualty excess of loss reinsurance protects cedents from a clash of
exposures from multiple insureds or from one large severe event. The Company
does not write casualty excess of loss business at a level where frequency of
loss is anticipated. Marine and aviation coverages can be triggered by
physical damage perils and
 
                                     10K-5
<PAGE>
 
may also entail casualty coverages arising from the same loss event. Crop
reinsurance provides hail and other defined property coverage for growing
crops. Satellite reinsurance protects the reinsured primarily for losses
arising from launch failure and in-orbit breakdown. Political risk includes
coverages for losses arising from contract frustration, confiscation,
repatriation and international trade credit transactions.
 
 Adjustment premiums, reinstatement premiums and no claims bonuses
 
  Due to the changing nature of a reinsurer's exposure under an excess of loss
contract, certain contracts contain adjustable premium clauses. The reinsurer
receives an initial deposit premium, with the final premium calculated at the
end of the contract period using a pre-negotiated percentage of the ceding
company's gross net annual premium income. The adjustment premium is the
difference between the initial deposit and the revised premium and can be
either an additional or return premium.
 
  In addition, the Company experiences adjustment premiums on its pro rata of
property catastrophe reinsurance treaties. The Company estimates premiums
written using reports received from ceding companies adjusted for previous
years' experiences of actual premiums against estimated premiums. These
estimates are revised during the contract period as more information as to
actual premiums written by the ceding companies is received. Any differences
between the estimate and the revised information are booked as adjustments
during the period the revised information is received.
 
  Certain excess of loss contracts contain a no claims bonus clause. Where no
claim is made under the contract, the ceding company is entitled to a pre-
determined return premium, which is referred to as a "no claims bonus". A
liability for the "no claims bonus" is established at the same time the gross
written premium is recorded. If a loss occurs, the no claims bonus is reversed
in the period in which the loss is notified to the Company.
 
 Geographic Diversification
 
  The Company seeks to diversify its property catastrophe exposures across
geographic zones in order to optimize its spread of risk. For the year ended
September 30, 1998, excluding the premiums written by LaSalle Re Capital,
adjustment premiums, reinstatement premiums and no claims bonuses, 48% of the
Company's net premiums written represented U.S.-based risks. Within the United
States, the Company's largest exposure on a zonal basis is the West Coast,
including Hawaii and Alaska. The remaining 52% of net premiums written were
spread in other territories around the world. This distribution of risk is
subject to change and is dependent upon rates available in various zones. As a
result of long-term relationships between the Company's management and certain
clients and brokers, the Company has developed a strong base of regional
business in the U.S. This business assists the Company in diversifying its
U.S.-based risks and makes more efficient use of its capital by limiting
multi-zone exposures. In the year ended September 30, 1998, this regional
business represented a significant component of the Company's U.S.-based net
premiums written.

 Program Limits
 
  Property catastrophe reinsurance is usually arranged in a series of layers,
which form an individual program. The Company may write one or more of these
layers with each layer constituting a separate contract. The following table

UNDERWRITING
 
  The Company's principal underwriting strategy is to underwrite property
catastrophe exposures within clearly defined parameters that permit thorough
analysis and appropriate pricing of each of the Company's reinsurance
contracts. Underwriting decisions are made following analysis of each
reinsurance contract based on the expected incremental return on equity in
relation to the Company's overall portfolio of reinsurance contracts.
 
                                     10K-7
<PAGE>
 
  The Underwriting/Actuarial Committee of the Board has set limits on the
Company's aggregate exposure. The Company uses various methods to evaluate and
monitor its exposure to loss. The Company diversifies its property catastrophe
exposures worldwide and within each geographic zone and also maintains
exposure limits within each geographic zone. Aggregate exposures also are
controlled and monitored on a real-time basis using computer-based rating and
control systems. The Company imposes attachment points in its contracts at a
level that is expected to exceed frequency of loss and limits aggregate risk
exposure. In addition, the Company regularly reevaluates its pricing to ensure
that general market conditions remain attractive.
 
  The Company obtains information from brokers, potential cedents and other
sources, as appropriate, in order to make informed underwriting decisions. A
potential cedent generally is not accepted without a thorough examination of
its historical record, management, business strategy, underwriting policies
and risk management systems. The Company also seeks to select clients with
disciplined catastrophe management programs. The Company seeks to build long-
term relationships with its clients because the Company believes that it can
underwrite renewal business with greater precision.
 
  The Company uses computer-based modeling systems to estimate exposure to
loss and evaluate pricing adequacy of its reinsurance programs. These models
are also used in the analysis of projected return on equity and the monitoring
of aggregate exposures within geographic zones.
 
  For U.S.-based risks, the Company has developed a proprietary model called
L-CAM(TM) (LaSalle Catastrophe Analysis Model). L-CAM(TM) incorporates the
output of commercially available catastrophe simulation models and the
Company's internally-generated models. The commercially available models
include (i) CATMAP(TM), which uses market share data derived from zip code
and/or county aggregate data to develop individual contract and portfolio loss
statistics and (ii) IRAS(TM), which derives loss statistics based on
hypothetical risk location determined from the most detailed information
provided by the primary insurer. Models developed by the Company and used in
L-CAM(TM) include (i) the Modified Historical Event Model, which fits a Pareto
loss distribution to over 45 years of catastrophe loss data, adjusted for
inflation and demographic shifts, (ii) the Market Loss Pricing Model, which
uses underwriting-zone market share information to develop attachment and
exhaustion probabilities from which pricing input is determined, and (iii) the
Industry Peer Model, which is a portfolio management tool selecting treaties
in force with similar characteristics for pricing considerations.
 
  For non-U.S. based property catastrophe risks, the Company uses modeling
techniques which incorporate Pareto loss distributions with exposure rating
based on aggregate liabilities per geographic zone. The Company also examines
experience ratings of adjusted historical loss events and, for some non-U.S.
territories, uses a commercially available software program produced by EQECAT
International, which utilizes probabilistic and deterministic loss
calculations.
 
  For the other lines of reinsurance, the Company uses internal rating
techniques that incorporate, among other things, exposure and experience
ratings and thorough analysis of loss ratios and underwriting expenses
associated with the business to be reinsured. The Company carefully structures
the terms and conditions of its contracts to restrict coverage to the specific
perils intended.
 
  The results of these analyses are measured against the Company's current
portfolio and other known treaties in the market and combined with
management's knowledge of the client and the current reinsurance market
environment. Pricing and participation decisions are then made based on the
estimated exposure of losses and the potential impact of each contract on
incremental return on equity. In addition, the underwriting of all new
exposures is reviewed by the Chief Executive Officer or Chief Operating
Officer of the Company.
 
  Prior to October 1, 1998, underwriting services were provided to the Company
by CNA Bermuda pursuant to the Underwriting Services Agreement. A staff of
seven professionals with extensive experience in the reinsurance industry
served as the Company's underwriting team in Bermuda. This agreement was
terminated on October 1, 1998. On that date, all of the personnel assigned to
the Company by CNA Bermuda became employees of the Company and the
underwriting function formerly performed by CNA Bermuda was assumed by the
Company directly.

  In connection with the termination of the Underwriting Services Agreement,
the Company entered into an Underwriting Support Services Agreement with CRSC
and CNA Bermuda. Under the Underwriting Support Services Agreement, which
expires on September 30, 2001, CRSC provides underwriting support services to
the Company on a daily or hourly fee basis when and as requested by the
Company. The Company pays CNA Bermuda a $0.3 million annual retainer, which is
credited against CRSC's daily or hourly fees and associated travel expenses.
In recognition of the contribution made by CNA Bermuda to the development of
the Company's business, the Company has agreed, subject to certain conditions,
to pay CNA Bermuda, during the term of the Underwriting Support Services
Agreement, an underwriting profit commission of 1.67% of the aggregate net
underwriting profits of LaSalle Re for each fiscal year for which LaSalle Re's
loss ratio was 70% or less.
 
REINSURANCE PROTECTIONS PURCHASED
 
  Reinsurance premiums ceded are primarily in respect of a multi-year excess
of loss reinsurance program purchased by the Company, and various reinsurance
protections purchased by LaSalle Re Capital. The excess of loss program
provides coverage of $100 million in excess of the first $100 million of
losses per occurrence for a first loss event and $100 million excess of $100
million per occurrence on the second loss event and $100 million excess of
$150 million per occurrence on the third loss event over a three-year period
ended December 31, 2000, subject to a maximum aggregate recovery of $300
million. The Company is required to pay reinstatement premiums to reinstate
the second and third loss event coverages. The Company may participate on a
co-insurance basis for the third loss event.
 
  Coverage for the first loss is substantially funded by way of annual and
reinstatement premium obligations. Accordingly, this portion of the coverage
has been recorded as a financing arrangement whereby the consideration paid,
net of associated financing charges, is recorded as a deposit and included as
part of other assets in the consolidated balance sheet. The deposit asset is
adjusted at the balance sheet date to reflect the net present value of
expected future cash flows under that portion of the contract.
 
  The reinsurance is provided by a company that currently holds a rating of
"A+" (Superior) from A.M. Best and a claims-paying rating of "AAA" (Excellent)
from S&P.
 
MARKETING
 
  The Company markets its reinsurance products worldwide primarily through
reinsurance brokers. By marketing its products primarily through the broker
network, the Company limits the expense of establishing and maintaining
worldwide offices and marketing operations. The Company believes that its
broker relationships permit it to obtain business and monitor developments in
various lines of reinsurance in order to increase its writings when market
conditions in those lines are favorable.
 
  The Company maintains an office in London, England through LaSalle Re
Services. LaSalle Re Services introduces prospective customers to the Company
and provides an important liaison with brokers in the London market, assisting
in the distribution of marketing literature and collecting information for
LaSalle Re on demand and developments in the London reinsurance market
generally. In addition, LaSalle Re Services plays a key role in the Company's
marketing efforts in Europe.
 
  The Company strives to develop strong relationships with its brokers and
clients. Retention of clients permits the Company to use experience regarding
a client's underwriting practices and risk management systems to underwrite
its own business with greater precision. The Company also targets brokers and
clients that it believes will enhance the risk/return composition of its
portfolio, are capable of supplying detailed and accurate underwriting data
and can potentially add diversification to the Company's book of business.
Additionally, the Company believes that its level of capital and surplus
offers financial security and demonstrates to brokers and clients a high level
of commitment to property catastrophe reinsurance.
 
  The Company focuses on providing high quality service by promptly responding
to underwriting submissions, designing customized programs and offering lead
terms when circumstances warrant and paying valid claims within an average of
five days. The Company believes that it has established a reputation with its
brokers and clients for high quality service.
 
                                     10K-9
<PAGE>
 
  The Company received 2,022 contract submissions in the year ended September
30, 1998 as compared to 2,344 in the year ended September 30, 1997. The
Company is highly selective in accepting risks, extending coverage on only 937
(1997: 1,000 contracts), or 46.3% (1997: 42.7%) of the program submissions
received, in the year ended September 30, 1998. Subsidiaries and affiliates of
Aon Corporation (together with its affiliates, "Aon") were brokers for 17.4%
and 16.6% of the Company's gross written premiums in the years ended September
30, 1998 and 1997, respectively. Guy Carpenter & Company, Inc., together with
its affiliates, generated 17.1% and 15.5% of the Company's gross premiums
written for the years ended September 30, 1998 and 1997, respectively. E.W.
Blanch accounted for 9.1% of the Company's gross written premiums for the year
ended September 30, 1998. This percentage was 11.3% for the year ended
September 30, 1997. No other broker accounted for more than 10% of the
Company's gross premiums written for the years ended September 30, 1998 and
1997.
 
  Consistent with its emphasis on disciplined underwriting practices, the
Company is not obligated to accept any business from any intermediary,
including Aon, CNA or LaSalle Re Services. No intermediary has the authority
to bind the Company on any business.
 
RESERVES
 
  The Company establishes loss reserves for the ultimate settlement costs of
all losses and loss expenses incurred with respect to business written by it.
United States generally accepted accounting principles ("GAAP") do not permit
the Company to establish reserves with respect to its property catastrophe
reinsurance until an event occurs that may give rise to a claim. As a result,
only loss reserves applicable to losses incurred up to the reporting date may
be set aside, with no allowance for the provision of a contingency reserve to
account for expected future losses.
 
  The derivation of loss reserves involves the actuarial and statistical
projection at any given time of the Company's expectations of the ultimate
settlement of loss and loss expenses. These loss projections become necessary,
primarily, as a result of time lags associated with reinsurance loss
reporting. These lags are principally attributable both to claimant delays in
reporting to the primary carrier as well as primary and reinsurance company
delays in gathering statistics and subsequently reporting cession details to
the Company. As a result, in addition to the loss estimates reported by
primary insurers on known claims, actuarially projected estimates of reserves
applicable to both the development (growth) of known claims as well as the
emergence of new claims reports related to loss events which have been
incurred but not reported ("IBNR losses") prior to the evaluation date must be
developed. In addition to the impact of reporting lags upon the accuracy of
estimated loss liabilities, other factors have significant impact upon the
ultimate settlement of insured losses, including loss cost inflation, trends
in the amount of insurance purchased to the full value of insured properties
and trends in the size and demographics of insured populations. Loss reserve
estimates are not precise in that they necessarily involve an attempt to
predict the ultimate outcome of future loss reporting and settlement
activities.
 
  To establish appropriate loss reserves, the Company uses a combination of
data sources and commercially available catastrophe models. These models are
employed upon the occurrence of an event to arrive at estimates of losses to
the Company. In addition, grouped and individual contract data illustrating
the loss development history for prior similar events, as well as actual loss
emergence experience of the underlying insurers, are analyzed to assist in the
determination of suitable loss reserves. The data derived from the industry
sources, and supplemented with the client specific information, are then used
to arrive at estimates of loss emergence patterns and initial estimates of
ultimate loss ratios. These parameters are then applied, on a contract-by-
contract basis, to arrive at estimates of ultimate losses. These loss
estimates are then supplemented with the results derived from the catastrophe
models, and final loss estimates are selected and reduced for losses reported
to the Company to arrive at IBNR losses as of the date of evaluation. The
reserves for LaSalle Re Capital are separately derived primarily from an
analysis using expected loss ratios which is supplemented, when available, by
actuarial evaluations produced for the individual syndicates.
 
  The reserves are prepared quarterly and reviewed by the Company's executive
officers and the Board, and to the extent they develop upward or downward, the
results are reflected in the net income in the period in which
 
                                    10K-10
<PAGE>
 
the reserve deficiency or redundancy is evaluated. There can be no assurance
that the final loss settlements will not exceed the Company's loss reserve and
have a material adverse effect upon the Company's financial condition and
results of operations in a particular period.
 
  Prior to October 1, 1997, the Company determined its reserves with the
assistance of actuarial staff provided by ARC pursuant to the Administrative
Services Agreement.
 
INVESTMENTS
 
 Composition of Portfolio
 
  The Board has implemented a set of investment guidelines designed to meet
the Company's liquidity requirements and return objectives. The guidelines are
intended to be conservative, stressing preservation of principal, yield
enhancement through the identification of value and market inefficiencies,
market liquidity and risk reduction. The primary objective of the investment
portfolio, as set forth in the guidelines, is to maximize investment returns
consistent with these policies. The Company's investment guidelines are
reviewed periodically and are subject to change at the discretion of the
Board.

 Quality of Portfolio
 
  The Company has investment guidelines which restrict investments in
securities below an "AA" grade rating to 20% of the total portfolio, and only
10% of the total portfolio can be invested in "BBB" grade rating. During the
year, the Company amended the guidelines to allow up to $10 million to be
invested in risk based investments such as catastrophe bonds. These bonds may
carry a rating below "BBB". In addition, the guidelines restrict investments
in a single issuer to no greater than 5% of the market value of the portfolio
(except for U.S. and U.K. Government issues) and, with respect to country of
issue, to no greater than 25% of the market value of the portfolio, except for
U.S. and supernational borrowers.

 Maturity and Duration of Portfolio
 
  The Company's investment guidelines specify a one to four year duration for
the Company's investment portfolio, reflecting the need to maintain a liquid,
short duration portfolio to assure the Company's ability to pay claims on a
timely basis. The Company currently has a target duration for the portfolio of
three years and at September 30, 1998, the modified average duration of the
portfolio was 3.1 years. The Company expects to periodically reevaluate the
target duration in light of market conditions, including the level of interest
rates, and estimates of the duration of its liabilities.
 
  The following table summarizes the contractual maturities of the Company's
fixed maturity portfolio as of September 30, 1998 and 1997 (dollars in
millions):

 Equity Securities/Real Estate
 
  Pursuant to the Company's investment guidelines, the Company's investment
portfolio may not contain any direct investments in real estate, mortgage
loans or equity securities.
 
 Foreign Currency Exposures
 
  As at September 30, 1998, all of the Company's fixed maturity portfolio
except one hedged international bond was denominated in U.S. dollars. During
the year ended September 30, 1998, the Investment Committee of the Board
amended the investment guidelines to allow up to 5% of the market value of the
portfolio at the time of purchase to be invested in hedged international
bonds. Under this type of investment the currency risk is negated through the
use of forward contracts with the Company only being exposed to the interest
rate risk on the bond purchased. At September 30, 1998 the hedged
international bond was denominated in Canadian dollars and represented 1.2% of
the total fair value of the portfolio. In connection with this investment as
at September 30, 1998 the Company had a forward contract with a notional
principal amount outstanding of $5.5 million.
 
  In an effort to manage other areas of exposure to foreign currency exchange
rate fluctuations, the Company from time to time enters into foreign exchange
contracts. These contracts generally involve the exchange of one currency for
U.S. dollars at some future date. At September 30, 1998 and 1997, the Company
had no principal amounts outstanding. See "Quantitative and Qualitative
Disclosure About Market Risk."
 
 Investment Manager
 
  LaSalle Re has entered into an investment management agreement (the
"Investment Management Agreement") with Aon Advisors (UK) Limited ("Aon
Advisors"). Pursuant to the terms of the Investment Management Agreement, the
Company pays Aon Advisors a flat fee equal to 0.16375% per annum of the assets
under management. Prior to July 1, 1997, the Company paid Aon Advisors a fee
equal to 0.35% per annum of the first $100 million of assets under management,
0.25% per annum of the next $100 million of assets under management in excess
of $100 million and 0.15% per annum of any additional assets under management
in excess of $200 million. The terms of the Investment Management Agreement
were determined in arm's length commercial negotiations. The performance of,
and the fees paid to, Aon Advisors under the Investment Management Agreement
are reviewed periodically by the Investment Committee of the Board.

COMPETITION
 
  The property catastrophe reinsurance industry is highly competitive. The
Company competes, and will continue to compete, with major U.S. and non-U.S.
insurers and property catastrophe reinsurers, including other Bermuda-based
property catastrophe reinsurers and CNA, some of which have greater financial
and organizational resources than the Company. A recent trend in the property
catastrophe reinsurance industry has been the utilization of the capital
markets in structuring reinsurance agreements using catastrophe bonds, swaps
and other types of derivative instruments. There may be established or new
companies of which the Company is not aware who may be planning to enter the
property catastrophe reinsurance market or existing reinsurers who may be
planning to raise additional capital. In addition, Lloyd's began to allow
capital from corporate investors in 1994. Competition in the types of
reinsurance business that the Company underwrites is based on many factors,
including rates and other terms and conditions offered, services provided,
ratings assigned by independent rating agencies, speed of claims payment and
reputation, the perceived financial strength and experience of the reinsurer
in the line of reinsurance to be written.
 
  In April 1996, LaSalle Re received an initial rating from A.M. Best of "A-"
(Excellent). In August 1997, the rating was upgraded to "A" (Excellent). The
current rating received by LaSalle Re represents the fourth highest in the
rating scale used by A.M. Best. In October 1996, LaSalle Re received an
initial rating of its claims paying ability from S&P of "A" (Good). This
rating received represents the sixth highest in the rating scale used by S&P.
Such ratings are based on factors of concern to cedents and brokers and are
not directed toward the protection of investors. Such ratings are neither a
rating of securities nor a recommendation to buy, hold or sell such
securities. Insurance ratings are one factor used by brokers and cedents as a
means of assessing the financial strength and quality of reinsurers. In
addition, a cedent's own rating may be adversely affected by the lack of a
rating of its reinsurer. Therefore, a cedent may elect to reinsure with a
competitor of the Company that has a higher insurance rating. Similarly, the
lowering or loss of a rating in the future could adversely affect the
Company's ability to compete.
 
  Other than being a corporate member of selected Lloyd's syndicates, the
Company is not licensed or admitted as an insurer in any jurisdiction other
than Bermuda and has no plans to become so licensed or admitted. Because
jurisdictions in the United States do not permit insurance companies to take
credit for reinsurance obtained from unlicensed or non-admitted insurers on
their statutory financial statements unless security is posted, the Company's
reinsurance contracts generally require it to post a letter of credit or
provide other security for outstanding claims and/or unearned premiums. In
order to post these letters of credit, the Company generally is required to
provide the issuing banks with collateral equal to such amounts. As a result
of the size of the Company's capitalization, the Company does not believe that
its non-admitted status in any jurisdiction has, or should have, a material
adverse effect on its ability to compete or obtain business in the property
catastrophe reinsurance market in which it operates, principally because many
of the Company's competitors are not admitted or licensed in United States
jurisdictions. However, there can be no assurance that increased competitive
pressure from current reinsurers and future market entrants or the Company's
non-admitted status will not adversely affect the Company.
 
EMPLOYEES
 
  As of December 1, 1998, the Company employed 31 people. The Company believes
that its employee relations are satisfactory. None of the Company's employees
are subject to collective bargaining agreements, and the Company knows of no
current efforts to implement such agreements at the Company.
 
REGULATION
 
 Bermuda
 
  The Insurance Act 1978, as amended, and related regulations (the "Insurance
Act"). As a holding company, the Company is not subject to Bermuda insurance
regulations. However, the Insurance Act, which regulates the insurance
business of LaSalle Re and LaSalle Re Capital, provides that no person shall
carry on an insurance business in or from within Bermuda unless registered as
an insurer under the Insurance Act by the Minister of Finance (the
"Minister"). The Minister, in deciding whether to grant registration, has
broad
 
                                    10K-13
<PAGE>
 
discretion to act as he thinks fit in the public interest. The Minister is
required by the Insurance Act to determine whether the applicant is a fit and
proper body to be engaged in the insurance business and, in particular,
whether it has, or has available to it, adequate knowledge and expertise. The
registration of an applicant as an insurer is subject to its complying with
the terms of its registration and such other conditions as the Minister may
impose at any time.
 
  An Insurance Advisory Committee appointed by the Minister advises him on
matters connected with the discharge of his functions, and sub-committees
thereof supervise and review the law and practice of insurance in Bermuda,
including reviews of accounting and administrative procedures.
 
  The Insurance Act imposes on Bermuda insurance companies solvency and
liquidity standards and auditing and reporting requirements and grants to the
Minister powers to supervise, investigate and intervene in the affairs of
insurance companies. Although LaSalle Re Capital is governed by the Insurance
Act, it is exempted from complying with most of the Act filings required by
insurance companies by section 57 of the Insurance Act. The solvency and
liquidity standards and auditing and reporting requirements of the Insurance
Act are summarized below.
 
  Significant aspects of the Bermuda insurance regulatory framework are set
forth below.
 
  Cancellation of Insurer's Registration. An insurer's registration may be
canceled by the Minister on certain grounds specified in the Insurance Act,
including failure of the insurer to comply with its obligations under the
Insurance Act or, if in the opinion of the Minister after consultation with
the Insurance Advisory Committee, the insurer has not been carrying on
business in accordance with sound insurance principles.
 
  Independent Approved Auditor. Every registered insurer must appoint an
independent auditor who will annually audit and report on the Statutory
Financial Statements and the Statutory Financial Return of the insurer, both
of which, in the case of LaSalle Re, are required to be filed annually with
the Registrar of Companies (the "Registrar"), who is the chief administrative
officer under the Insurance Act. The independent auditor of the insurer must
be approved by the Minister and may be the same person or firm that audits the
insurer's financial statements and reports for presentation to its
shareholders.
 
  Loss Reserve Specialist. LaSalle Re is registered as a Class 4 insurer.
Every Class 4 insurer is required to submit an annual loss reserve opinion
when filing the annual Statutory Financial Return. This opinion must be issued
by a Loss Reserve Specialist. The Loss Reserve Specialist, who will normally
be a qualified casualty actuary, must be approved by the Minister.
 
  Statutory Financial Statements. An insurer must prepare Statutory Financial
Statements annually. The Insurance Act prescribes rules for the preparation
and substance of such Statutory Financial Statements (which include, in
statutory form, a balance sheet, income statement, statement of capital and
surplus and detailed notes thereto). The insurer is required to give detailed
information and analyses regarding premiums, claims, reinsurance and
investments. The Statutory Financial Statements are not prepared in accordance
with GAAP and are distinct from the financial statements prepared for
presentation to the insurer's shareholders under the Companies Act 1981 of
Bermuda (the "Companies Act"), which financial statements may be prepared in
accordance with GAAP. LaSalle Re is required to submit the Statutory Financial
Statements as part of the annual Statutory Financial Return.
 
  Minimum Solvency Margin. The Insurance Act provides that the statutory
assets of an insurer must exceed its statutory liabilities by an amount
greater than the prescribed minimum solvency margin which varies with the type
of business and class of registration of the insurer and the insurer's net
premiums written and loss reserve level. As a registered Class 4 insurer,
LaSalle Re is required to maintain a minimum solvency margin equal to the
greatest of $100 million, 50% of its net premiums written (but may not deduct
more than 25% of gross premiums written when computing net premiums written)
or 15% of its loss and other certain insurance reserves. At September 30,
1998, LaSalle Re's actual statutory capital and surplus was $506.0 million,
compared to its minimum solvency margin requirement of $100 million.
 
                                    10K-14
<PAGE>
 
  Minimum Liquidity Ratio. The Insurance Act provides a minimum liquidity
ratio for general business. An insurer engaged in general business is required
to maintain the value of its relevant assets at not less than 75% of the
amount of its relevant liabilities. Relevant assets include cash and time
deposits, quoted investments, unquoted bonds and debentures, first liens on
real estate, investment income due and accrued, accounts and premiums
receivable and reinsurance balances receivable. There are certain categories
of assets which, unless specifically permitted by the Minister, do not
automatically qualify as relevant assets, such as unquoted equity securities,
investments in and advances to affiliates, real estate and collateral loans.
The relevant liabilities are total general business insurance reserves and
total other liabilities less deferred income tax and sundry liabilities (by
interpretation, those not specifically defined).
 
  Annual Statutory Financial Return. LaSalle Re is required to file annually
with the Registrar a Statutory Financial Return no later than four months
after its financial year end (unless specifically extended). The Statutory
Financial Return includes, among other matters, a report of the approved
independent auditor on the Statutory Financial Statements of the insurer; a
declaration of the statutory ratios; a solvency certificate; the Statutory
Financial Statements themselves; the opinion of the approved Loss Reserve
Specialist and certain details concerning ceded reinsurance. The solvency
certificate and the declaration of the statutory ratios must be signed by the
principal representative and at least two directors of the insurer who are
required to state (among other matters) whether the Minimum Solvency Margin
and, in the case of the solvency certificate, the Minimum Liquidity Ratio have
been met, and the independent approved auditor is required to state whether in
its opinion it was reasonable for them to so state and whether the declaration
of the statutory ratios complies with the requirements of the Insurance Act.
The Statutory Financial Return must include the opinion of the Loss Reserve
Specialist in respect of the loss and loss expense provisions of LaSalle Re.
Where an insurer's accounts have been audited for any purpose other than
compliance with the Insurance Act, a statement to that effect must be filed
with the Statutory Financial Return.
 
  Supervision, Investigation and Intervention. The Minister may appoint an
inspector with extensive powers to investigate the affairs of an insurer if
the Minister believes that an investigation is required in the interest of the
insurer's policyholders or persons who may become policyholders. In order to
verify or supplement information otherwise provided to him, the Minister may
direct an insurer to produce documents or information relating to matters
connected with the insurer's business.
 
  If it appears to the Minister that there is a risk of the insurer becoming
insolvent or that it is in breach of the Insurance Act or any conditions
imposed upon its registration, the Minister may (among other matters) direct
the insurer not to take on any new insurance business; not to vary any
insurance contract if the effect would be to increase the insurer's
liabilities; not to make certain investments; to realize certain investments;
to maintain in or transfer to the custody of a specified bank, certain assets;
not to declare or pay any dividends or other distributions or to restrict the
making of such payments; and/or to limit its premium income.
 
  Principal Representative. An insurer is required to maintain a principal
office in Bermuda and to appoint and maintain a principal representative in
Bermuda. For the purpose of the Insurance Act, the principal office of LaSalle
Re is at the Company's offices at 25 Church Street, Hamilton HM FX Bermuda,
and Andrew Cook is the principal representative of LaSalle Re. Without a
reason acceptable to the Minister, an insurer may not terminate the
appointment of its principal representative, and the principal representative
may not cease to act as such, unless 30 days' notice in writing to the
Minister is given of the intention to do so. It is the duty of the principal
representative, within 30 days of his reaching the view that there is a
likelihood of the insurer for which he acts becoming insolvent or its coming
to his knowledge, or his having reason to believe, that an "event" has
occurred, to make a report in writing to the Minister setting out all the
particulars of the case that are available to him. Examples of such an "event"
include failure by the reinsurer to comply substantially with a condition
imposed upon the reinsurer by the Minister relating to a solvency margin or a
liquidity or other ratio.
 
  Class 4 Insurer. LaSalle Re is registered as a Class 4 insurer and, as such:
(i) is required to maintain a minimum statutory capital and surplus equal to
the greatest of $100 million, 50% of its net premiums written (but may not
deduct more than 25% of gross premiums written when computing net premiums
written) or 15% of its loss and other insurance reserves; (ii) is required to
file annually within four months following the end of
 
                                    10K-15
<PAGE>
 
the relevant financial year with the Registrar, inter alia, a Statutory
Financial Return together with a copy of its annual Statutory Financial
Statements and an opinion of a Loss Reserve Specialist in respect of its loss
and loss expense provisions; (iii) is prohibited from declaring or paying any
dividends during any financial year if it is in breach of its minimum solvency
margin or minimum liquidity ratio or if the declaration or payment of such
dividends would cause it to fail to meet such margin or ratio (if it has
failed to meet its minimum solvency margin or minimum liquidity ratio on the
last day of any financial year, LaSalle Re will be prohibited, without the
approval of the Minister, from declaring or paying any dividends during the
next financial year); (iv) is prohibited from declaring or paying in any
financial year dividends of more than 25% of its total statutory capital and
surplus (as shown on its previous financial year's statutory balance sheet)
unless it files (at least 7 days before payment of such dividends) with the
Registrar an affidavit stating that it will continue to meet the required
margins; (v) is prohibited, without the approval of the Minister, from
reducing by 15% or more its total statutory capital, as set out in its
previous year's financial statements; and (vi) is required, at any time it
fails to meet its solvency margin, within 30 days (45 days where total
statutory capital and surplus falls to $75 million or less) after becoming
aware of that failure or having reason to believe that such failure has
occurred to file with the Minister a written report containing certain
information.
 
  Certain Other Considerations. As "exempted" companies, the Company, LaSalle
Re and LaSalle Re Capital may not, without the express authorization of the
Bermuda legislature or a license granted by a Minister, participate in certain
business transactions, including: (i) the acquisition or holding of land in
Bermuda (except that required for its business and held by way of lease or
tenancy agreement for a term not exceeding 50 years); (ii) the taking of
mortgages on land in Bermuda in excess of $50,000; or (iii) the carrying on of
business of any kind in Bermuda, except in furtherance of the business carried
on outside Bermuda or as permitted under the Companies Act.
 
  The Bermuda government actively encourages foreign investment in "exempted"
entities like the Company that are based in Bermuda but do not operate in
competition with local businesses. As well as having no restrictions on the
degree of foreign ownership, the Company, LaSalle Re and LaSalle Re Capital
are not currently subject to taxes on their income or dividends or to any
foreign exchange controls in Bermuda. In addition, there currently is no
capital gains tax in Bermuda, and profits can be accumulated by the Company,
LaSalle Re and LaSalle Re Capital, as required, without limitation.
 
  The Companies Act prohibits a company from declaring or paying a dividend,
or making a distribution out of contributed surplus, if there are reasonable
grounds for believing that (i) the company is, or would after the payment be,
unable to pay its liabilities as they come due; or (ii) the realizable value
of the company's assets would thereby be less than the aggregate of its
liabilities and shareholders' equity. The foregoing restriction applies to the
Company, LaSalle Re and LaSalle Re Capital as Bermuda exempted companies.
 
 LaSalle Re Capital
 
  LaSalle Re Capital became a Corporate Member of Lloyd's in December 1996 and
commenced underwriting effective January 1, 1997. LaSalle Re Capital is only
licensed to carry on business related to Lloyd's. As a Corporate Member,
LaSalle Re Capital is 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 under The Financial
Services Act of 1986. Instead, Lloyd's is self regulating by virtue of The
Lloyd's Act of 1982, through by-laws, regulations and codes of conduct written
by the Council, which governs the market. Under the Council, there are two
boards, the Market Board and the Regulatory Board. The Market Board is led by
working members of the Council and is responsible for strategy and policy
signing. The Regulatory Board is responsible for the regulation of the market,
compliance and the protection of policyholders. Under the terms of its license
(as a "member of a recognised association of underwriters") under the
Insurance Act, LaSalle Re Capital is required to meet and maintain the
solvency requirements of Lloyd's.
 
  As a Corporate Member of Lloyd's, LaSalle Re Capital is required to file
audited financial statements and an annual return, which is part of the annual
declaration of compliance process. The annual declaration of compliance sets
out the financial position of the Corporate Member and confirms details of its
directors and controllers. In addition, LaSalle Re Capital is required to file
an audited solvency return either confirming the
 
                                    10K-16
<PAGE>
 
value of funds at Lloyd's ("FAL") held by the member as at the previous
December 31, or that it held no FAL at that date. Lloyd's will compare the
value of a Corporate Member's FAL derived from the solvency return with its
underwriting assets and liabilities as reported by the syndicates on which it
participates. Where a negative solvency position is disclosed, the Corporate
Member is required to provide sufficient additional funds to cover the
shortfall. As at December 14, 1998, LaSalle Re Capital had filed a solvency
return for the 1997 underwriting year.
 
  In addition to the above Lloyd's requirements, under the terms of its
license under the Insurance Act, LaSalle Re Capital must send to the Bermuda
Registrar of Companies within 30 days after submission of the annual solvency
return and declaration of compliance to Lloyd's a copy of such documents
together with a copy of the audited annual statements of each of the
syndicates in which LaSalle Re Capital participates. Further, LaSalle Re
Capital must also appoint and maintain a principal representative in Bermuda.
 
 United States, United Kingdom and Other
 
  LaSalle Re is registered as an insurer and is subject to regulation and
supervision in Bermuda. LaSalle Re is not admitted or authorized to do
business in any jurisdiction except Bermuda. The insurance laws of each state
of the United States do not directly regulate the sale of reinsurance within
their jurisdictions by alien insurers, such as LaSalle Re. Nevertheless, the
sale of reinsurance by alien reinsurers, such as LaSalle Re, to insurance
companies domiciled or licensed in United States jurisdictions is indirectly
regulated by state "credit for reinsurance" laws that operate to deny
financial statement credit to ceding insurers unless the non-admitted alien
reinsurer posts acceptable security for ceded liabilities and agrees to
certain contract provisions (e.g., insolvency and intermediary clauses).
Although the insurance laws of United States jurisdictions generally exempt
the business of reinsurance from "doing business" laws, the Company conducts
its business at its principal offices in Bermuda and does not maintain an
office in the United States, and its personnel do not solicit, advertise,
settle claims or conduct other insurance activities in the United States. All
policies are issued and delivered and premiums are received outside the United
States. The Company does not believe that it is subject to the insurance laws
of any state in the United States. From time to time, there have been
congressional and other initiatives in the United States regarding the
supervision and regulation of the insurance industry, including proposals to
supervise and regulate alien reinsurers. While none of these proposals have
been adopted to date on either the federal or state level, there can be no
assurance that federal or state legislation will not be enacted subjecting the
Company to supervision and regulation in the United States, which could have a
material adverse effect on the Company. In addition, no assurance can be given
that if the Company were to become subject to any laws of the United States or
any state thereof or of any other country at any time in the future, it would
be in compliance with such laws.
 
  LaSalle Re does not intend to maintain an office or to solicit, advertise,
settle claims or conduct other insurance activities in any jurisdiction other
than Bermuda where the conduct of such activities would require that LaSalle
Re be so admitted. Consistent with this policy, LaSalle Re established LaSalle
Re Services as a subsidiary in the United Kingdom to operate a London "contact
office" at the London Underwriting Center. LaSalle Re Services is not
registered as an insurer in England or in any other jurisdiction. The Company
believes that LaSalle Re Services is not required to be registered as an
insurance company in the United Kingdom, and that the activities of LaSalle Re
Services do not cause the Company to be subject to regulation as an insurance
company in the United Kingdom.
 
ITEM 2. PROPERTIES
 
  The Company's executive offices, which are leased, are located in Hamilton,
Bermuda. In addition, the Company leases office space in London, England.
 
ITEM 3. LEGAL PROCEEDINGS
 
  None.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
 
  No matters were submitted to a vote of shareholders of the Company during
the fourth fiscal quarter of the fiscal year ended September 30, 1998.

  In February 1997, in connection with the Preferred Offering, the Board
confirmed the dividend policy pursuant to which the Company intends to
distribute as dividends to holders of Common Shares and Exchangeable Non-
Voting Shares in each fiscal year, 50% to 60% of the amount by which its net
income (before minority interest) from the prior fiscal year exceeds the
amount of dividends payable on preferred shares of the Company in the current
fiscal year. The actual amount and timing of any future dividends is at the
discretion of the Board and is dependent upon the profits and financial
requirements of the Company as well as loss experience, business opportunities
and any other factors that the Board deems relevant. In addition, if the
Company has funds available for distribution, it may nevertheless determine
that such funds should be retained for the purposes of replenishing capital,
expanding premium writings or other purposes. The Company is a holding company
whose principal source of income is cash dividends and other permitted
payments from LaSalle Re. The payment of dividends by LaSalle Re to the
Company is restricted under Bermuda law and regulation, including Bermuda
insurance law. Under the Insurance Act, LaSalle Re is prohibited from paying
dividends of more than 25% of its opening statutory capital and surplus unless
it files an affidavit (at least 7 days before payment of such dividends)
stating that it will continue to meet the required solvency margin and minimum
liquidity ratio requirements and from declaring or paying any dividends
without the approval of the Minister of Finance if it failed to meet its
required margins on the last day of the previous fiscal year. The Insurance
Act also requires LaSalle Re to maintain a minimum solvency margin and minimum
liquidity ratio and prohibits
 
                                    10K-19
<PAGE>
 
dividends which would result in a breach of these requirements. In addition,
LaSalle Re is prohibited under the Insurance Act from reducing its opening
total statutory capital by 15% or more without the approval of the Minister of
Finance. As a result of these factors, there can be no assurance that the
Company's dividend policy will not change or that the Company will declare or
pay any dividends.

</TABLE>
 
  The overall decrease in gross premiums written was primarily due to a
reduction in gross premiums written in the Company's core product, property
catastrophe reinsurance, from $144.7 million for the year ended September 30,
1997 to $104.2 million, a decrease of 28.0%. Of this reduction approximately
60.0% related to the international property catastrophe book and 40.0% related
to the United States property catastrophe book. The reduction was greater in
the international property catastrophe book as the Company reduced its line
sizes on certain proportional treaties pursuant to its policy of reducing
aggregate exposures in a declining rate environment. This accounted for
approximately $7.7 million of the decrease in the international property
catastrophe book. Approximately 25% of the decrease in the United States
property catastrophe book related to a multi-year contract which was written
in the year ended September 30, 1997 and hence no written premium was recorded
in the year ended September 30, 1998. The remaining decrease in the total
property catastrophe book was due to continuing competitive rates. Based on
the Company's experience, rates for property catastrophe business written in
the year ended September 30, 1998, were approximately 15% and 10% below those
experienced in the year ended September 30, 1997 for international and United
States property catastrophe business respectively. This led to lower priced
premiums in comparison to those written in the year ended September 30, 1997
and the non-renewal of contracts in certain cases where the Company considered
the business to be under-priced. For the year ended September 30, 1998, the
Company experienced a 6.3% reduction in the number of property catastrophe
contracts written from 1,000 in the year ended September 30, 1997 to 937
contracts for the year ended September 30, 1998.

  The decline in gross premiums written by the Company was partially offset by
an increase of $14.0 million in respect of gross premiums written in other
non-property catastrophe lines. The increase was primarily due to increased
gross premiums written by LaSalle Re Capital, which commenced underwriting as
a corporate member of Lloyd's in January 1997, the second quarter of the 1997
fiscal year. For the year ended September 30, 1998, LaSalle Re Capital wrote
gross premiums of $21.0 million compared to $14.1 million for the year ended
September 30, 1997. Also, the Company increased the size of its terrorism and
political risks book which accounted for approximately $1.0 million of gross
premiums written for the year ended September 30, 1997 compared with
approximately $4.4 million for the year ended September 30, 1998.
 
  In addition, for the year ended September 30, 1997, an amount of $10.3
million relating to adjustment premiums, reinstatement premiums and no claims
bonuses produced a reduction in gross premiums written. In the year ended
September 30, 1998, there was a positive adjustment to gross premiums written
of $0.1 million. This was principally due to insignificant premium adjustments
and, due to increased loss activity, to increased reinstatement premiums and
lower no claims bonuses.
 
  Premiums ceded for the year ended September 30, 1998 were $7.8 million
compared to $7.7 million for the year ended September 30, 1997 and related to
reinsurance protection purchased by LaSalle Re with effect from January 1,
1997 and to various reinsurance protections purchased by LaSalle Re Capital.
Ceded premiums amortized increased from $1.9 million in the year ended
September 30, 1997 to $6.1 million for the year ended September 30, 1998. This
increase was due primarily to the reinsurance protections purchased by LaSalle
Re Capital, which were amortized in line with the premiums earned by LaSalle
Re Capital.
 
  Net premiums earned decreased 5.7% to $154.6 million for the year ended
September 30, 1998 from $163.9 million for the year ended September 30, 1997.
This decrease was the result of reduced premiums earned on the Company's core
property catastrophe business that was partially offset by increased earned
premiums on those premiums written by LaSalle Re Capital. Premiums written by
LaSalle Re Capital are earned over a period of 18-24 months from the inception
date of the underlying contracts. Premiums on property catastrophe excess of
loss contracts are earned over the period coverage is provided, which is
generally 12 months. Under proportional property catastrophe contracts, with
the risks underlying the contracts incepting throughout the contract period,
premiums are generally earned over 18 months. Premiums on other lines of
business are earned over the period for which coverage is provided, which
generally ranges between 12 months and 60 months.
 
  Net investment income increased 3.6% to $34.3 million for the year ended
September 30, 1998 from $33.1 million for the year ended September 30, 1997.
This increase was attributable to a larger average investment base compared to
the year ended September 30, 1997. Annualized investment income as a
percentage of the average market value of invested assets was 6.0% for the
year ended September 30, 1998 compared to 6.1% for the year ended September
30, 1997.
 
  Net realized gains on investments were $5.6 million for the year ended
September 30, 1998 compared to $0.6 million for the year ended September 30,
1997. During the year ended September 30, 1998 the Company realized gains on
investments as part of an exercise undertaken to increase the credit quality
of the portfolio. In addition, during the last quarter of the year ended
September 30, 1998, the Company took advantage of market conditions by
realizing some of the large unrealized gains in the portfolio. The proceeds
from this exercise were reinvested in securities with marginally lower yields.
 
  Other income was derived from a contract under which the Company provided
certain reinsurance related services. This contract was not renewed January 1,
1998.
 
  The following table sets forth the Company's combined ratios for the years
ended September 30, 1998 and 1997:

  Losses and loss expenses incurred increased 206.2% from $31.2 million for
the year ended September 30, 1997 to $95.5 million for the year ended
September 30, 1998. This was due to an increase in the number of worldwide
catastrophic events that affected the Company during the year ended September
30, 1998. The largest loss event to affect the Company was Hurricane Georges,
which occurred in September 1998. The Company established a $25 million loss
provision for this event that represented 26% of the losses incurred for the
year ended September 30, 1998. In addition, throughout the year ended
September 30, 1998, the Company incurred losses in respect of various weather-
related events, notably U.K. Midland floods ($7.0 million), Canadian winter
freeze ($4.3 million) and various U.S. storms ($2.4 million). The Company
sustained a number of claims relating to aggregate stop loss and excess of
loss contracts, which accounted for approximately $16.8 million or 18% of
losses incurred. A large percentage of these aggregate losses incurred in the
year ended September 30, 1998 related to losses that had occurred in prior
years. This was due to the extended loss reporting periods on these contracts,
a number of which had a period of 24 months after the expiry of the contract
within which to report losses. Also, as a result of increasing other lines of
business the Company incurred losses relating to LaSalle Re Capital ($5.0
million), satellite coverages ($3.0 million), various risk excess coverages
($3.0 million) and political risks coverages ($1.7 million). As a result of
the current year loss activity, the Company has increased the level of
incurred but not reported reserves. Losses and loss expenses incurred during
the year ended September 30, 1997 primarily included $12.0 million for floods
in Eastern Europe, $6.1 million in respect of various international windstorms
and winter storm activity in the United States and $4.6 million adverse
development on Hurricane Fran (which occurred in September 1996).
 
  Underwriting expenses decreased 12.9% from $26.0 million for the year ended
September 30, 1997 to $22.7 million for the year ended September 30, 1998. As
a percentage of net premiums earned, underwriting expenses were 14.6% for the
year ended September 30, 1998 compared to 15.9% for the year ended September
30, 1997. Fees accrued pursuant to the Underwriting Services Agreement as a
percentage of net premiums earned decreased to 2.3% for the year ended
September 30, 1998 from 4.0% for the year ended September 30, 1997. This was
due to the higher loss activity and lower premium earnings in the year ended
September 30, 1998 compared with the year ended September 30, 1997. The
Company's level of brokerage fees and ceding commissions increased to 12.3% of
net premiums earned for the year ended September 30, 1998 from 11.8% of net
premiums earned for the year ended September 30, 1997. The increase was partly
due to an increase in earned premiums written by LaSalle Re Capital, whose
expense ratio was approximately 20% and partly due to an increase in the
average cost of writing proportional business.
 
  Operational expenses decreased 29.4% from $12.7 million for the year ended
September 30, 1997 to $8.9 million for the year ended September 30, 1998. As a
percentage of net premiums earned, operational expenses were 5.7% during the
year ended September 30, 1998 compared to 7.7% for the year ended September
30, 1997. Effective October 1, 1997, the Administrative Services Agreement
with ARC was terminated and all of the personnel assigned to the Company by
ARC became employees of the Company, with the Company assuming the functions
previously performed by ARC. This generated a reduction in operational
expenses of approximately $2.3 million, as the fees paid to ARC were in excess
of the additional costs assumed by the Company. In addition, the Company
experienced a reduction in executive compensation of approximately $2.4
million, due partly to a decline in the fair value of stock appreciation
rights and partly to reduced bonus provisions. These decreases were offset by
increased costs of $1.0 million relating to LaSalle Re Capital and fees paid
to directors.
 
  Corporate expenses decreased 72.2% from $1.8 million for the year ended
September 30, 1997 to $0.5 million for the year ended September 30, 1998. The
costs incurred in the year ended September 30, 1998 related to costs
associated with the Company's investigation of potential merger and
acquisition transactions. Corporate expenses for the year ended September 30,
1997 included costs associated with the Secondary Offering, the Preferred
Offering, the Tender Offer, the formation costs of LaSalle Re Capital, the
Company's move to the New York Stock Exchange and fees incurred with respect
to the CatEPut. Corporate expenses do not include the underwriting discounts
associated with the various offerings. These costs were borne by the selling
shareholders in the Secondary Offering. In respect of the Preferred Offering,
the underwriting discount was charged to additional paid in capital.

  Interest expense increased 11.8% from $1.7 million in the year ended
September 30, 1997 to $1.9 million for the year ended September 30, 1998. The
increase was due to additional financing charges associated with the deposit
portion of LaSalle Re's ceded reinsurance contract in the year ended September
30, 1998. As the contract incepted January 1, 1997, only three quarters of the
annual charge was included in the year ended September 30, 1997. Other
interest expenses related to the annual administration fee and the ongoing
commitment fees payable on the Company's credit facility. As at September 30,
1998, there were no borrowings under this facility.
 
  Foreign exchange gains in the year ended September 30, 1998 were negligible
at $0.2 million compared to losses of $3.0 million in the year ended September
30, 1997. The losses in the year ended September 30, 1997 resulted from the
unfavorable closing of a sterling forward contract, and an overall
strengthening of the U.S. dollar against the major foreign currencies in which
the Company wrote premiums.
 
  Earnings per Common Share were $3.06 for the year ended September 30, 1998
and $5.55 for the year ended September 30, 1997. Earnings per Common Share
assuming dilution were $2.80 for the year ended September 30, 1998 and $5.14
for the year ended September 30, 1997. The weighted average number of shares
outstanding used in the calculation of earnings assuming dilution decreased
from 22,998,936 for the year ended September 30, 1997 to 20,919,405 for the
year ended September 30, 1998. The decrease in the weighted average number of
shares outstanding resulted primarily from the repurchase of shares in the
Tender Offer in April 1997.
 
 Year Ended September 30, 1997 Compared with Year Ended September 30, 1996
 
  Gross premiums written decreased 9.9% to $171.4 million for the year ended
September 30, 1997 from $190.2 million for the year ended September 30, 1996.
This decrease was due primarily to a reduction in international property
catastrophe premiums to $73.1 million for the year ended September 30, 1997
from $88.9 million for the year ended September 30, 1996. This reduction, in
turn, was a result of the competitive rate environment, which led to a
reduction in the number of international property catastrophe contracts
written. The Company experienced a 5.3% decrease in property catastrophe
premiums written in the United States. The decline in gross premiums written
by the Company was partially offset by an increase of $14.9 million in respect
of other non-property catastrophe lines written. This increase primarily
related to premiums written in the year ended September 30, 1997 by LaSalle Re
Capital, which was accepted into Lloyd's with effect from January 1, 1997.
Further, for the year ended September 30, 1997 compared to the year ended
September 30, 1996, the Company experienced a reduction in reinstatement
premiums of $6.2 million due to more favorable loss experience and an increase
in overall negative premium adjustments of $7.6 million.
 
  Premiums ceded for the year ended September 30, 1997 were $7.7 million
compared to nil in the year ended September 30, 1996. This was primarily
attributable to reinsurance protection purchased by LaSalle Re with effect
from January 1, 1997 and to reinsurance purchased by LaSalle Re Capital. Ceded
premiums amortized were $1.9 million for the year ended September 30, 1997
compared to nil in the year ended September 30, 1996.
 
  Net premiums earned decreased 16.0% to $163.9 million for the year ended
September 30, 1997 from $195.1 million for the year ended September 30, 1996.
This decrease was principally due to the overall decrease in premiums written
in the previous fiscal year and the year ended September 30, 1997.
 
  Net investment income increased 23.5% to $33.1 million for the year ended
September 30, 1997 from $26.8 million for the year ended September 30, 1996.
This increase was principally attributable to an increase in yields during the
year ended September 30, 1997, together with a larger average investment base
compared to the year ended September 30, 1996. Annualized investment income as
a percentage of the average market value of invested assets was 6.07% for the
year ended September 30, 1997 compared to 5.44% for the year ended September
30, 1996.
 
  Net realized gains on investments were $0.6 million during the year ended
September 30, 1997 compared to $0.4 net realized losses during the year ended
September 30, 1996.

  Other income was derived from reinsurance related services providing an
annual fee of $0.3 million. As the provision of these services began on
January 1, 1997, there was no corresponding income in the year ended September
30, 1996.
 
  The following table sets forth the Company's combined ratios for the years
ended September 30, 1997 and 1996:

      Combined ratio................................     42.6%          46.0%
</TABLE>
 
  Losses and loss expenses incurred decreased 39.4% to $31.2 million for the
year ended September 30, 1997 from $51.5 million for the year ended September
30, 1996. This decrease was a result of the limited number of worldwide
catastrophic events that affected the Company during the year. Losses and loss
expenses incurred during the year ended September 30, 1997 primarily included
$12.0 million for floods in Eastern Europe, $6.1 million in respect of various
international windstorms and winter storm activity in the United States and
$4.6 million adverse development on Hurricane Fran, which occurred in
September 1996. Losses and loss expenses incurred during the year ended
September 30, 1996 included additional reserves of $14.2 million for
Hurricanes Marilyn and Luis and various other losses emanating from the 1996
hurricane season and end of the 1995 hurricane season and international
storms.
 
  Underwriting expenses decreased 4.8% from $27.3 million for the year ended
September 30, 1996 to $26.0 million for the year ended September 30, 1997. As
a percentage of net premiums earned, underwriting expenses were 15.9% for the
year ended September 30, 1997 compared to 14.0% for the year ended September
30, 1996. Of this increase, 0.6% was due to the settlement of significant
profit commissions on one program underwritten in previous fiscal years, which
had better than expected loss ratios, and the provision for profit commission
on contracts underwritten in the current fiscal year. In addition, the
business underwritten by LaSalle Re Capital has higher underwriting costs,
which increases the Company's percentage of underwriting expenses to net
premiums earned. The Company experienced an increase in the fees and profit
commission accrued under the Underwriting Services Agreement from 3.7% of net
premiums earned for the year ended September 30, 1996 to 4.0% net premiums
earned for the year ended September 30, 1997.
 
  Operational expenses increased 14.4% to $12.7 million for the year ended
September 30, 1997 from $11.1 million for the year ended September 30, 1996.
This increase was substantially due to additional executive compensation and
expenses relating to the operation of LaSalle Re Capital.
 
  Corporate expenses were $1.8 million for the year ended September 30, 1997,
compared with $0.9 million for the year ended September 30, 1996. Corporate
expenses for the year ended September 30, 1997 included costs associated with
the Secondary Offering, the Preferred Offering, the Tender Offer, the
formation costs of LaSalle Re Capital, the Company's move to the New York
Stock Exchange and fees incurred with respect to the CatEPut. In 1996,
corporate expenses included costs associated with the initial public offering
and all costs associated with the establishment of the Company's credit
facility. Corporate expenses do not include the underwriting discounts
associated with the various offerings. These costs were borne by the selling
shareholders in the initial public offering and the Secondary Offering. In
respect of the Preferred Offering, the underwriting discount was charged to
additional paid in capital.
 
  Interest expense was $1.7 million during the year ended September 30, 1997
compared to $0.2 million in the year ended September 30, 1996. This increase
was due to financing charges associated with the deposit portion of LaSalle
Re's ceded reinsurance contract. Other interest expenses related to the annual
administration fee and the ongoing commitment fees payable on the Company's
credit facility. As at September 30, 1997, there were no borrowings under this
facility.

  Foreign exchange losses in the year ended September 30, 1997 were $3.0
million compared to losses of $1.1 million in the year ended September 30,
1996. The losses in the year ended September 30, 1997 resulted from the
unfavorable closing of a sterling forward contract, and an overall
strengthening of the U.S. dollar since January 1, 1997 against the major
foreign currencies in which the Company writes premiums. The losses for the
year ended September 30, 1996 were the result of several factors, including
the decrease in the value of yen and deutschmarks relative to the U.S. dollar.
Additionally, the Company's sterling foreign exchange contracts precluded
participation in the appreciation of sterling in the third fiscal quarter
above the Company's average forward rate.
 
  Earnings per Common Share were $5.55 for the year ended September 30, 1997
and $5.70 for the year ended September 30, 1996. Earnings per Common Share
assuming dilution were $5.14 for the year ended September 30, 1997 and $5.40
for the year ended September 30, 1996. Following the Tender Offer, the
adjusted weighted average number of Common Shares outstanding decreased from
23,967,870 for the year ended September 30, 1996 to 22,998,936 for the year
ended September 30, 1997. This decrease generated a 6.6% accretive effect on
the Company's 1997 net income per share.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  As a holding company, the Company's assets consist primarily of all of the
outstanding voting stock of LaSalle Re. The Company's cash flows depend
primarily on dividends and other permitted payments from LaSalle Re.
 
  LaSalle Re's sources of funds consist of premiums written, investment income
and proceeds from sales and redemptions of investments. Cash is used primarily
to pay losses and loss expenses, brokerage, commissions, excise taxes,
administrative expenses and dividends. Under the Insurance Act, LaSalle Re is
prohibited from paying dividends of more than 25% of its opening statutory
capital and surplus unless it files an affidavit (at least 7 days before
payment of such dividends) stating that it will continue to meet the required
solvency margin and minimum liquidity ratio requirements and from declaring or
paying any dividends without the approval of the Minister of Finance if it
failed to meet its required margins in the previous fiscal year. The Insurance
Act also requires LaSalle Re to maintain a minimum solvency margin and minimum
liquidity ratio and prohibits dividends that would result in a breach of these
requirements. In addition, LaSalle Re is prohibited under the Insurance Act
from reducing its total opening statutory capital by 15% or more without the
approval of the Minister of Finance. LaSalle Re currently meets its
requirements under the Insurance Act. In addition, the payment of dividends by
LaSalle Re is subject to the rights of holders of the Exchangeable Non-Voting
Shares to receive a pro rata share of any dividend and to its need to maintain
shareholders' equity adequate to support the level of LaSalle Re's reinsurance
operations.
 
  Operating activities provided net cash of $96.0 million for the year ended
September 30, 1998 and $98.6 million for the year ended September 30, 1997.
Cash flows from operations in future years may differ substantially from net
income. Cash flows are affected by loss payments, which, due to the nature of
the reinsurance coverage provided by LaSalle Re, are generally expected to
comprise large loss payments on a limited number of claims and can therefore
fluctuate significantly from year to year. The irregular timing of these large
loss payments can create significant variations in operating cash flows
between periods. LaSalle Re funds such payments from cash flows from
operations and sales of investments.
 
  As a result of the potential for large loss payments, LaSalle Re maintains a
substantial portion of its assets in cash and marketable securities. As of
September 30, 1998, 80.1% of its total assets were held in cash and marketable
securities. To further mitigate the uncertainty surrounding the amount and
timing of potential liabilities and to minimize interest rate risk, LaSalle Re
maintains a short average duration for its investment portfolio. The modified
average duration of the investment portfolio, including cash, was 3.1 years at
September 30, 1998. At September 30, 1998, the fair value of the Company's
total investment portfolio, including cash, was $606.8 million.
 
  Cash and cash equivalents increased from $54.8 million at September 30, 1997
to $85.3 million at September 30, 1998. The increase was due to proceeds
received on the sale of bonds in late September, which
 
                                    10K-25
<PAGE>
 
were not re-invested until post year-end. In addition the Company required
funds for the payment of losses, primarily as a result of Hurricane Georges.
 
  The Company has adopted the Statement of Financial Accounting Standard No.
115 ("SFAS 115") to account for its marketable securities with all of the
Company's investments classified as "available for sale". Under this
classification, investments are recorded at fair market value and any
unrealized gains or losses are reported as "Accumulated other comprehensive
income", a separate component of shareholders' equity. In accordance with SFAS
No. 130 "Reporting of Comprehensive Income", the movement in unrealized gains
or losses on these investments are disclosed as part of other comprehensive
income. The unrealized gain on the investment portfolio net of amounts
attributable to minority interest was $13.8 million at September 30, 1998
compared to an unrealized gain of $2.0 million at September 30, 1997.
 
  At September 30, 1998, 86.5% of the securities held in the Company's
investment portfolio were fixed-income securities rated "AA" or better and
97.9% were fixed-income securities rated "A" or better by S&P or Moody's. No
single investment comprised more than 5% of the overall portfolio. As at
September 30, 1998, issuers from the Far East and Asia represented 5.7% of the
investment portfolio. These securities had a market value of $33.6 million and
an aggregate unrealized gain of $0.4 million. All of these securities had an
average credit rating of AAA as assigned by S&P or Moody's, as at September
30, 1998.
 
  During the year ended September 30, 1998, the Company modified its
investment guidelines to allow the purchase of mortgage backed securities. In
addition during the year ended September 30, 1998 the Company entered into a
swap agreement to provide cash flow to a counterparty in the event of a
defined earthquake activity in Japan. Receipts to the Company are accounted
for as investment income and are based on a percentage of the notional amount
of the swap. The contract exposes LaSalle Re to a maximum cash outflow of the
original notional amount of $3.0 million should the defined earthquake event
occur. In addition, the Company is exposed to credit loss in the event of
nonperformance by the counter-party to the remittance of interest payments as
required by the swap.
 
  Reinsurance balances receivable were $86.8 million at September 30, 1998
compared to $80.0 million at September 30, 1997. This increase was due to the
inclusion of receivable balances relating to the business underwritten by
LaSalle Re Capital. At September 30, 1998, these receivable balances were
$31.2 million compared to $11.3 million as at September 30, 1997. Given the
three-year accounting methodology utilized by Lloyd's, these balances will not
be received until after the year 2000.
 
  Deferred acquisition costs increased from $11.9 million at September 30,
1997 to $13.4 million at September 30, 1998 whereas unearned premiums
decreased from $88.5 million at September 30, 1997 to $83.1 million at
September 30, 1998. Although the volume of gross premiums written has
declined, there has been an increase in the average cost of the business
written due to increased costs associated with proportional business and an
increased level of LaSalle Re Capital business.
 
  Prepaid reinsurance premiums have increased from $5.8 million at September
30, 1997 to $7.6 million at September 30, 1998. The increase primarily related
to an increase in the level of the risk transfer portion of the Company's
reinsurance program and to the level of reinsurance ceded by LaSalle Re
Capital.
 
  Other assets increased from $22.6 million at September 30, 1997 to $31.7
million as at September 30, 1998. This was primarily due to the deposit
portion of the ceded reinsurance contract, which is accounted for in
accordance with SFAS No 113 and the no claims bonus provision of the contract.
In addition, following the termination of the Administrative Services
Agreement the Company paid $1.5 million to purchase the existing fixed assets.
The Company has also purchased additional fixed assets during the year ended
September 30, 1998.
 
  At September 30, 1998, the liability for unpaid losses and loss expenses was
$97.9 million compared to $45.5 million at September 30, 1997. The increase of
$52.4 million from September 30, 1997 was primarily due to the losses which
occurred in the fourth quarter on which the Company made an estimate of its
total liability, notably Hurricane Georges. In addition, the Company increased
its reserves for unpaid losses on other lines of business and the business
written by LaSalle Re Capital which, given the three-year accounting
methodology, will not be paid until after the year 2000.
 
                                    10K-26
<PAGE>
 
  Other liabilities increased from $22.8 million as at September 30, 1997 to
$29.2 million as at September 30, 1998. The increase of $6.4 million was
primarily due to liabilities established for the purchased reinsurance
protections for both the Company and LaSalle Re Capital and operating expenses
of LaSalle Re Capital. This was offset partially by a reduction in the fees
accrued pursuant to the Underwriting Services Agreement with CNA Bermuda which
was terminated October 1, 1998 and the Administrative Services Agreement with
ARC which was terminated October 1, 1997.
 
  In accordance with the terms of certain reinsurance contracts written by the
Company, the Company has posted letters of credit in the amount of $8.3
million as of September 30, 1998 as compared to $8.7 million as of September
30, 1997 to support outstanding loss reserves. In connection with LaSalle Re
Capital's support of three Lloyd's syndicates, the Company has posted letters
of credit in the amount of $16.6 million (equivalent to (Pounds)9.8 million).
In addition, in connection with the Japanese earthquake swap, the Company has
posted a letter of credit of $3.0 million. All letters of credit are secured
by a lien on the Company's investment portfolio equal to 115% of the amount of
the outstanding letters of credit.
 
  The Company paid dividends on its Common Shares of $0.71 per share in
October 1997 and $0.75 per share in January, April and July 1998. The Company
paid a quarterly dividend of $0.5469 per share to holders of its Series A
Preferred Shares in December 1997 and March, June and September 1998. As of
September 30, 1998, dividends due but not yet declared on the Series A
Preferred Shares amounted to $0.5 million.
 
  Based on the Company's net income for the year ended September 30, 1998, the
Company currently expects to declare dividends of $0.375 per Common Share each
quarter during the 1999 fiscal year. The actual amount and timing of any
future Common Share dividends is at the discretion of the Board. The
declaration and payment of any dividends is dependent upon the profits and
financial requirements of the Company and other factors, including certain
legal, regulatory and other restrictions. There can be no assurance that the
Company's dividend policy will not change or that the Company will declare or
pay any dividends in future periods.
 
  LaSalle Re Capital is committed to provide capital support for the 1999
underwriting year to the same Lloyd's syndicates as it supported in 1998. The
level of support is not expected to change materially from that provided in
1998. The Company has no material commitments for capital expenditures.
 
  The Company has in place a $100 million committed line of credit from a
syndicate of banks. The proceeds from the credit facility may only be used to
buy preferred shares of LaSalle Re that, in turn, may use the proceeds of such
purchase to meet current cash requirements. The facility matures December 1,
2000, and is secured by a pledge ("legal mortgage") of all the capital stock
of LaSalle Re held by the Company, including any preferred shares that may be
issued by LaSalle Re to the Company. The line of credit contains various
covenants, including limitations on incurring additional indebtedness;
restrictions on the sale or lease of assets not in the ordinary course of
business; maintenance of a ratio of consolidated total debt to consolidated
tangible net worth of no more than 0.40 to 1.00; maintenance of tangible net
worth at the end of each fiscal year of the greater of $300 million or 70% of
net premiums written; maintenance of statutory capital of LaSalle Re of at
least $300 million, increasing to $350 million at the end of calendar year
1998 and $400 million at the end of calendar year 1999 and thereafter; and
maintenance of a ratio of net premiums written to statutory capital at the end
of any fiscal quarter for the four fiscal quarters then ended of no more than
1.00 to 1.00 in each case. The Company may pay dividends and make other
restricted payments so long as, after giving effect to such restricted
payments, no event of default has occurred. Dividends and restricted payments
are limited to 50% of consolidated net income for its immediately preceding
fiscal year less amounts paid on the Series A preferred shares. In order for
the Company to pay dividends in excess of 50% of consolidated net income, the
Company would have to renegotiate certain terms of its credit facility. As of
September 30, 1998, the credit facility had not been utilized.
 
  The Company's financial condition and results of operations are influenced
by both internal and external forces. Loss payments, investment returns and
premiums may be impacted by changing rates of inflation and other economic
conditions. Cash flows from operations and the liquidity of its investment
portfolio are, in the Company's opinion, adequate to meet the Company's
expected cash requirements over the next 12 months.

  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131
"Disclosures about Segments of an Enterprise and Related Information." This
statement is effective for financial statements issued for periods beginning
after December 15, 1997 and requires the Company to report financial and
descriptive information about its reportable operating segments. This standard
will require additional disclosure and will be adopted by the Company for the
year ended September 30, 1999.
 
  In February 1998, the Financial Accounting Standards Board issued SFAS No.
132 "Employers' Disclosures about Pensions and other Postretirement Benefits".
This statement is effective for fiscal years beginning after December 15,
1997. As the provisions of the statement need not be applied to immaterial
items, the Company considers it unlikely the statement will change its
disclosures significantly.
 
  In June 1998, the Financial Accounting Standards Board issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities". This statement
is effective for all fiscal quarters of fiscal years beginning after June 15,
1999. Given the limited number of transactions currently entered into by the
Company that are covered by the statement, the Company does not anticipate any
significant changes to its current financial reporting.
 
 Year 2000 Issue
 
  The Company's goal is to ensure that its computer systems and the computer
systems of third parties that are material to the Company's operations (such
as the computer systems of service providers, suppliers and brokers) will be
capable of correctly processing information relating to dates in and after the
year 2000 ("Year 2000 compliant"). The Company does not believe that it faces
any material Year 2000 compliance problems with respect to its non-information
technology systems.
 
  The Company engaged International Business Machines Corporation ("IBM") to
prepare an assessment and strategy report outlining the steps needed to make
the Company's computer systems Year 2000 compliant. IBM's report indicated
that certain of the Company's systems, applications and business interfaces
have Year 2000 date problems which will require an estimated 359 person-days
to correct. The Company has set a target date of March 31, 1999 for the
completion of the necessary conversions to the following systems: (i) the
Senator underwriting management system, (ii) the RSG reinsurance system, (iii)
other software and hardware components and infrastructure, (iv) enterprise-
wide spreadsheet and database files, (v) broker compliance and (vi) supplier
compliance. The Company has budgeted $0.3 million for the overall Year 2000
compliance effort and has expensed $0.06 million to date for the IBM
assessment and strategy report. Given the current level of estimated costs, it
is not anticipated that the costs of Year 2000 compliance will have a material
impact on the Company's future results.
 
  A number of risk factors, including but not limited to the following, could
affect the Company's plans to achieve Year 2000 compliance by March 31, 1999
within the current budget:
 
  . As the Company is currently completing its installation of the Senator
    underwriting management system, any delay in completing that installation
    could delay the Year 2000 conversion of components of that system. To
    provide for that contingency, the Company has contracted with outside
    service providers to ensure that the Company's current RSG reinsurance
    system is Year 2000 compliant by January 31, 1999.
 
  . The target date of March 31, 1999 for Year 2000 compliance is based on
    the December 1998 commencement and timely progress of the actual software
    conversions. Any delays in starting or implementing the conversion
    process will present a significant hindrance to completing the project by
    the target date.
 
  . Information technology ("IT") resources to implement Year 2000
    conversions are in short supply and the supply of external contractor
    resources is likely to decrease further as the Year 2000 approaches. This
    shortage of resources could escalate the cost of performing the
    conversion work beyond the current estimates. The Company intends to
    maximize internal IT resources by freezing all discretionary changes to
    applications during the Year 2000 conversion and does not anticipate that
    this will delay other significant IT projects.
 
                                    10K-28
<PAGE>
 
  . The Company has no control over the timing of Year 2000 compliance by
    external brokers and suppliers who interface with the Company. However,
    the Company has distributed a Year 2000 compliance questionnaire to its
    suppliers and brokers and, as of November 12, 1998, 63.5% of suppliers
    and 61.5% of brokers, including the Company's major suppliers and
    brokers, had adequately responded to the Company's questionnaire.
 
  The Company also assesses the effect of the Year 2000 issue on the business
it underwrites, considering the exposure to Year 2000 related losses on a
contract by contract basis at the time of underwriting.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK
 
  The Company's major market risk exposure is changing interest rates,
primarily in the United States as the Company has a portfolio of fixed
maturity investments, of which all except one hedged international bond are
denominated in U.S. dollars. A change in interest rates will affect the fair
value of the Company's investments and will lead to fluctuations in
"Accumulated Other Comprehensive Income" on the balance sheet. The Company
limits this risk by setting a maximum portfolio duration of four years, which
is stipulated in the Company's investment guidelines. The Company does not use
derivative financial instruments to manage market risk in its U.S. dollar
denominated portfolio. In addition, the Company places its investments with
high credit quality issuers and limits the amount of credit exposure with
respect to particular ratings categories and any one issuer or country of
issuer. The table below (expressed in millions of U.S. dollars) presents the
par value amounts and related weighted average interest rates by year of
maturity for the Company's U.S. dollar denominated investment portfolio.

  During the year ended September 30, 1998, the Company amended its investment
guidelines to permit investment in hedged international bonds. Under this type
of investment, the currency risk is negated through the use of forward
contracts, with the Company only being exposed to the interest rate risk on
the bond purchased. As at September 30, 1998, only one bond had been purchased
with a par value of Canadian dollars $7 million, an interest rate of 5.3% and
a maturity date of 2007.
 
  The fair value of the cash and cash equivalents and the fixed interest
securities as at September 30, 1998 was $606.8 million.
 
  In addition, the Company has foreign currency risk on both reinsurance
balances receivable and reinsurance balances payable (including payables
relating to losses). The Company does not currently utilize derivative
instruments to manage the Company's exposure to foreign currency movements. In
the past the Company has used forward contracts to eliminate the risk;
however, given the uncertainty in cash flows this was not deemed to be an
efficient management technique. As of September 30, 1998, the majority of the
Company's net receivable/payable position is denominated in U.S. dollars. As
at September 30, 1998, the largest foreign currency exposure is sterling, as
the Company had a net receivable balance of (Pounds)14.1 million. A 5%
increase or decrease in the year-end sterling/U.S. dollar exchange rate would
produce a gain or loss, respectively, of $1.2 million. Given the limited
amount of net receivable balances in other currencies, no other currency
movement has been considered.

                         INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
LaSalle Re Holdings Limited
 
  We have audited the consolidated financial statements of LaSalle Re Holdings
Limited and subsidiaries as listed in the accompanying index. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of LaSalle Re
Holdings Limited and subsidiaries as of September 30, 1998 and 1997 and the
results of their operations and their cash flows for each of the years in the
three-year period ended September 30, 1998 in conformity with generally
accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 YEARS ENDED SEPTEMBER 30, 1998, 1997 AND 1996
 (EXPRESSED IN THOUSANDS OF UNITED STATES DOLLARS, EXCEPT SHARE AND PER SHARE
                                     DATA)
 
1. GENERAL
 
  The Company was incorporated on September 20, 1995 under the laws of Bermuda
to act as an investment holding company. LaSalle Re Limited ("LaSalle Re") was
incorporated on October 26, 1993 under the laws of Bermuda and commenced
operations on November 22, 1993. LaSalle Re is licensed under the Insurance
Act, 1978 as amended by the Insurance Amendment Act, 1995 of Bermuda (the
"Act") to write insurance business and operates as a multi-line reinsurance
company, with emphasis on property catastrophe business.
 
  Property catastrophe reinsurance covers unpredictable events such as
hurricanes, windstorms, hailstorms, earthquakes, fires, industrial explosions,
freezes, riots, floods and other man-made or natural disasters. Because the
Company has large aggregate exposures to these risks, the Company expects that
its claims experience will be characterized by relatively low frequency and
high severity claims. The occurrence of claims from catastrophic events is
likely to result in substantial volatility in the Company's financial results
for any particular period. 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 attachment points.
 
  On August 26, 1994, LaSalle Re incorporated a subsidiary company in the
United Kingdom, LaSalle Re (Services) Limited, to act as a representative
office for the Company. In addition, on June 11, 1996, LaSalle Re incorporated
a subsidiary company in Bermuda, LaSalle Re Corporate Capital Ltd., to provide
capital support to selected Lloyd's syndicates.
 
  In November 1995, the Company and LaSalle Re consummated an offer (the
"Exchange Offer") pursuant to which, among other things, the founding
shareholders of LaSalle Re (the "Founding Shareholders") exchanged their
capital stock of LaSalle Re for common shares of the Company (the "Common
Shares") and, in certain circumstances, exchangeable non-voting shares of
LaSalle Re (the "Exchangeable Non-Voting Shares"). The Exchange Offer was
accounted for as if it were a pooling of interests of combining enterprises
under common control.
 
  On November 27, 1995, the Company and certain Founding Shareholders also
consummated an initial public offering of 4,312,500 Common Shares. Of these
shares, 2,920,500 were sold by Founding Shareholders and 1,392,000 by the
Company. The proceeds from the sale of 1,392,000 shares sold by the Company
were used to enable LaSalle Re to redeem shares of its capital stock.
 
  The consolidated financial statements include the results of the Company and
the Company's share of LaSalle Re and its subsidiaries for all periods
presented.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
  The accompanying consolidated financial statements are prepared in
accordance with United States generally accepted accounting principles
("GAAP"). The preparation of financial statements in conformity with GAAP
requires management to make estimates and assumptions that affect the reported
and disclosed amounts of assets and liabilities and disclosure of contingent
assets and liabilities at the date of the financial statements and the
reported amounts of revenues and expenses during the period. Actual results
could differ from those estimates. The estimates most susceptible to
significant change are those used in determining the liability for unpaid
losses and loss expenses and the amount of ultimate premiums written.

                          LASALLE RE HOLDINGS LIMITED
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The following are the significant accounting policies adopted by the
Company:
 
 (a) Principles of consolidation
 
  The consolidated financial statements include the financial statements of
LaSalle Re Holdings Limited, LaSalle Re Limited and its subsidiaries, LaSalle
Re (Services) Limited and LaSalle Re Corporate Capital Ltd. All significant
inter-company balances and transactions have been eliminated in consolidation.
 
 (b) Minority interest
 
  Minority interest represents the Founding Shareholders' ownership of the
Exchangeable Non-Voting Shares in LaSalle Re. These shares are held by certain
Founding Shareholders who would otherwise hold, or cause another shareholder
to hold, directly, indirectly or constructively, in excess of 9.9% of the
voting power of the Company or LaSalle Re. The Exchangeable Non-Voting Shares
in LaSalle Re are exchangeable, at the option of the holder, for Common Shares
of the Company, on a one-for-one basis, unless the board of directors of the
Company determines such exchange may cause actual or potential adverse tax
consequences to the Company or any shareholder. The Exchangeable Non-Voting
Shares will at all times rank as to assets, dividends and in all other
respects on a parity with the Common Shares of LaSalle Re, except that they do
not have the right to vote on any matters except as required by Bermuda law
and in connection with certain actions by the Company.
 
  Changes in the minority interest of LaSalle Re as a result of the exchange
of such shares for shares in the Company are recorded at historic cost by
transferring an appropriate portion of the minority interest to the various
components of shareholders' equity. The minority's share of income as recorded
in the income statement is calculated using the minority's ownership
percentage as at the balance sheet date. Minority interest as reported in the
balance sheet represents the minority's current proportionate share of LaSalle
Re and its subsidiaries' net assets.
 
 (c) Premiums earned and deferred acquisition costs
 
  Premiums written are estimated by management based upon reports received
from ceding companies. These estimates are adjusted where a contract contains
a no claims bonus with a provision for the potential liability recorded
simultaneously with the written premium. In addition, estimates are subject to
review with adjustments recorded in the period in which the actual amounts are
determined. Premiums on property catastrophe excess of loss contracts are
earned on a pro rata basis over the period the coverage is provided, which is
generally 12 months. Under pro rata property catastrophe contracts, the risks
underlying the contracts incept throughout the policy period and premiums
generally are earned over an 18 month period. Premiums written by LaSalle Re
Corporate Capital Ltd. are derived from reports submitted to the Company by
the syndicates. These premiums are earned in accordance with the related
underlying risk attachment periods, which average between 18-24 months.
Unearned premiums represent the portion of premiums written which are
applicable to the unexpired terms of the policies in force.
 
  Acquisition costs, mainly brokerage, commissions, underwriting fees and
excise taxes related to unearned premiums, are deferred and amortized to
income over the period in which the premiums are earned. Future earned
premiums and anticipated losses and loss adjustment expenses related to those
premiums are considered in determining the recoverability of deferred
acquisition costs. The Company does not consider anticipated future investment
income in determining if a premium deficiency exists.
 
 (d) Reinsurance
 
  In the normal course of business, the Company seeks to reduce its exposure
to losses that may arise from catastrophes and cause unfavorable underwriting
results by reinsuring certain levels of risks with other reinsurers.

<PAGE>
 
                          LASALLE RE HOLDINGS LIMITED
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In accordance with Statement of Financial Accounting Standard ("SFAS") No.
113 "Accounting and Reporting for Reinsurance of Short-Duration and Long-
Duration Contracts", contracts providing indemnification against loss or
liability relating to insurance risk have been accounted for as reinsurance.
Reinsurance premiums are reported as prepaid reinsurance premiums and
amortized over the contract period in proportion to the amount of reinsurance
protection provided. Where the contract provides for return premiums, these
are accrued based on loss experience through to the balance sheet date.
Reinsurance contracts, which do not satisfy the conditions for reinsurance
accounting under SFAS No. 113, are accounted for as deposits.
 
 (e) Losses and loss expenses
 
  The liability for outstanding losses and loss expenses is based on reports
and individual case estimates received from ceding companies. An amount is
included for losses and loss expenses incurred but not reported on the basis
of reports received from ceding companies and an actuarial analysis. The
amount included as losses incurred in respect of business written by LaSalle
Re Corporate Capital Ltd. is derived from an analysis of expected loss ratios.
 
  Given the inherent nature of major catastrophic events, considerable
uncertainty underlies the assumptions and associated estimated reserves for
losses and loss expenses. These estimates are reviewed regularly and, as
experience develops and new information becomes known, the reserves are
adjusted as necessary. Such adjustments, if any, are reflected in results of
operations in the period in which they are determined and are accounted for as
changes in estimates. Due to the inherent uncertainty in estimating the
liability for losses and loss expenses, there can be no assurance that the
ultimate liability will not exceed recorded amounts, with a resulting material
effect on the Company. Based on the current assumptions used in calculating
the liability, management believes that the Company's recorded amount is
adequate to meet its future obligations.
 
  Amounts recoverable from reinsurers are estimated in a manner consistent
with the underlying liabilities.
 
  Liabilities are recorded without consideration of potential salvage or
subrogation recoveries that are estimated to be immaterial. Such recoveries,
when realized, are reflected as a reduction of losses incurred.
 
 (f) Investments
 
  The Company's investments comprise fixed interest securities and short term
investments, such as certificates of deposit or commercial paper. All
investments are considered to be available for sale under the definition
included in SFAS No. 115 "Accounting and Reporting for Certain Investments in
Debt and Equity Securities". As such, they are reported at fair value with
unrealized gains and losses, net of amounts attributable to the minority
interest, reported as other comprehensive income.
 
  Purchases and sales of investments are accounted for on the trade date of
the transaction.
 
 (g) Investment income
 
  Investment income, net of investment expenses, is accrued to the balance
sheet date and includes amortization of premiums and accretion of discounts
relative to fixed interest securities purchased at prices different to par
value.
 
  Realized gains or losses on sales of investments are determined on the basis
of specific identification and are included in the consolidated statements of
operations and comprehensive income.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 (h) Translation of foreign currencies
 
  The U.S. dollar is the Company's functional currency. Foreign currency
monetary assets and liabilities are translated at exchange rates in effect at
the balance sheet date. Unearned premiums and deferred acquisition costs are
translated at historic exchange rates. Foreign currency revenues and expenses
are translated at the exchange rates in effect at the date of the transaction.
Exchange gains and losses are included in the determination of net income, as
they arise.
 
  The Company has entered into foreign exchange contracts to manage the
currency risks associated with the receipt of non-U.S. dollar insurance
premiums. Realized and unrealized gains and losses on these contracts are
included in the determination of net income as they arise.
 
 (i) Fair value of financial instruments
 
  Fair value disclosures with respect to certain financial instruments are
separately included herein, where appropriate.
 
  The carrying values of other financial instruments, including cash and cash
equivalents, reinsurance balances receivable, accrued investment income,
promissory note receivable and other liabilities, approximate their fair value
due to the short term nature of the balances.
 
 (j) Other income
 
  Other income relates to fees earned in respect of reinsurance services
provided.
 
 (k) Corporate expenses
 
  Corporate expenses are recorded on an accruals basis.
 
 (l) Cash and cash equivalents
 
  For the purposes of the consolidated statements of cash flows, the Company
considers all time deposits and certificates of deposit with an original
maturity of 90 days or less as equivalent to cash.
 
 (m) Stock incentive compensation plans
 
  The Company has adopted SFAS No. 123 "Accounting for Stock-Based
Compensation". As allowed under this standard, the Company accounts for stock
option grants in accordance with APB opinion No. 25, "Accounting for Stock
Issued to Employees". Compensation expense for stock option grants is
recognized to the extent that the fair value of the stock exceeds the exercise
price of the option at the measurement date. Any resulting compensation
expense is recorded over the shorter of the vesting or service period.
 
  Pro forma disclosure of net income and earnings per share as if the fair
value based method of SFAS No. 123 had been adopted is provided in Note 10 to
the consolidated financial statements.
 
 (n) Earnings per common share
 
  Earnings per Common Share have been calculated in accordance with SFAS 128
"Earnings per Share". Earnings per Common Share are calculated by dividing net
income available to common shareholders by the weighted average number of
Common Shares outstanding. For the purposes of this calculation, the
exchangeable non-voting shares of LaSalle Re ("Exchangeable Non-Voting
Shares") are considered outstanding Common Shares of the Company due to the
exchangeable nature of the shares. Earnings per Common Share assuming dilution
is computed by dividing net income available to common shareholders by the sum
of the weighted average number of Common Shares outstanding and the dilutive
potential Common Shares outstanding during the period of calculation. Prior
period calculations have been restated to give effect to SFAS 128.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 (o) Accounting pronouncements
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131
"Disclosures about Segments of an Enterprise and Related Information." This
statement is effective for financial statements issued for periods beginning
after December 15, 1997 and requires the Company to report financial and
descriptive information about its reportable operating segments. This standard
will require additional disclosure and will be adopted by the Company for the
year ended September 30, 1999.
 
  In February 1998, the Financial Standards Board issued SFAS No. 132
"Employers' Disclosures about Pensions and other Postretirement Benefits".
This statement is effective for fiscal years beginning after December 15,
1997. As the provisions of the statement need not be applied to immaterial
items, the Company considers it unlikely the statement will change its
disclosures significantly.
 
  In June 1998, the Financial Standards Board issued SFAS No. 133 "Accounting
for Derivative Instruments and Hedging Activities". This statement is
effective for all fiscal quarters of fiscal years beginning after June 15,
1999. Given the limited number of transactions currently entered into by the
Company that are covered by the Statement, the Company does not anticipate any
significant changes to its current financial reporting.
 
3. INVESTMENTS AND INVESTMENT INCOME

4. REINSURANCE
 
  Reinsurance premiums ceded are primarily in respect of a multi-year excess
of loss reinsurance program purchased by the Company, and various reinsurance
protections purchased by LaSalle Re Corporate Capital Ltd. The excess of loss
program provides coverage of $100,000 in excess of the first $100,000 of
losses per occurrence for a first loss event and $100,000 excess of $100,000
per occurrence on the second loss event and $100,000 excess of $150,000 per
occurrence on the third loss event over a three-year period ended December 31,
2000, subject to a maximum aggregate recovery of $300,000. The Company is
required to pay reinstatement premiums to reinstate the second and third loss
event coverages. The Company may participate on a co-insurance basis for the
third loss event.
 
  Coverage for the first loss is substantially funded by way of annual and
reinstatement premium obligations. Accordingly, this portion of the coverage
has been recorded as a financing arrangement whereby the consideration paid,
net of associated financing charges, is recorded as a deposit and included as
part of other assets in the consolidated balance sheet. The deposit asset is
adjusted at the balance sheet date to reflect the net present value of
expected future cash flows under that portion of the contract. Interest
expense includes finance charges of $1,666 (1997: $1,470), which are being
amortized over the period of the contract using the interest method.
 
  The reinsurance agreement is secured by a company which currently holds a
rating of "A+" (Superior) from A.M. Best Company, Inc. and a claims-paying
rating of "AAA" (Excellent) from Standard & Poor's Ratings Services.
 
  The ceding of the reinsurance does not legally discharge the Company from
its liability to its reinsureds, since the Company is required to pay losses
and bear collection risk if the reinsurers fail to meet their obligations
under the reinsurance agreements. The effect of reinsurance on premiums
written and earned is as follows:

  During the year ended September 30, 1997, 95,679 options were exercised at a
price of $9.74. In addition, 136,350 options to purchase Exchangeable Non-
Voting Shares were bought by the Company at a price of $24.97 and subsequently
canceled. As at September 30, 1997, the Company and LaSalle Re had 136,350
options to purchase Common Shares and 1,967,751 options to purchase
Exchangeable Non-Voting Shares outstanding respectively.

  The original exercise price of the options was $16.67 per share, (which was
equal to the fair value of the Company's shares at the grant date), minus
dividend adjustments. The current exercise price is $6.78. As the options were
granted to certain of the Founding Shareholders and their affiliates as an
inducement to purchase stock in LaSalle Re, no compensation expense has been
recorded in connection with the options.
 
 (b)(i) Compensatory--stock appreciation rights
 
  In consideration for entering into an employment agreement with LaSalle Re,
the Company's Chief Executive Officer (the "Executive") was granted a total of
340,872 Stock Appreciation Rights (SARs) during 1994. Upon exercise, the SARs
entitle the Executive to a cash payment equal to the value of the SARs as of
the exercise date. Alternatively, at the Company's sole discretion, the SARs
will entitle the Executive to either (i) the number of Special Non-Voting
Shares of LaSalle Re equal to the aggregate value of the SARs divided by the
fair value of a Common Share at the exercise date, or (ii) upon payment of the
base value for each SAR, the number of Special Non-Voting Shares of LaSalle Re
equal to the number of SARs exercised.
 
  The value of each SAR equals the fair market value of a Common Share less
the base value on the exercise date, subject to anti-dilution adjustments. The
fair market value shall be determined by the board of directors of the
Company, but shall be based on the market price of the Common Shares. The base
value of each SAR at the time of issuance was $16.67, minus dividend
adjustments. The current base value is $6.78.
 
  The number of SARs which can be exercised is dependent upon the internal
rate of return achieved during the period from November 22, 1993 through to
the date of exercise and ending on March 30, 2004 or, if earlier, two years
after the Chief Executive Officer's termination of employment. SARs will not
be exercisable unless a targeted internal rate of return of at least 18% per
annum is achieved during the entire measurement period. The internal rate of
return is based upon the financial performance of LaSalle Re from inception to
November 27, 1995 and LaSalle Re Holdings Limited's consolidated performance
from that date forward. As at September 30, 1998, the number of SARs vested is
92,035, of which 68,174 became exercisable on January 1, 1997 and 23,861 on
January 1, 1998. The remaining balance of SARs may become exercisable on
January 1, 1999 if the Company's internal rate of return exceeds 18% through
to December 31, 1998. At September 30, 1998, the Company's internal rate of
return has exceeded 18%. During the fiscal year ended September 30, 1998, the
fair value of the SARs has decreased and therefore the Company has recorded a
reduction in the total liability relating to the SARs of $548 (1997: charge
$1,611; 1996: charge $909).
 
 (b)(ii) Compensatory--options
 
  In November 1995, the Company adopted a Long Term Incentive Plan (the
"Incentive Plan") which permits the award of various incentives to employees
of the Company, its subsidiaries and other persons providing services to those
companies.
 
  Under the Incentive Plan, the options granted vest ratably in five annual
installments over 5 years from the grant date, except for 85,218 options
granted in 1997 which vest ratably in three annual installments over 3 years
from the date of grant. The options can be exercised over a 10-year period,
commencing on the vesting date. The Plan has an anti-dilution provision, which
awards the option holder a number of shares of restricted stock in the event
that a dividend, when added to the value of all cash dividends previously paid
within the same fiscal year, exceeds 5% of the average book value per share
for the prior four quarters. During the year ended September 30, 1998, 26,995
shares of restricted stock (1997: 19,362) were awarded. The restricted stock
vests when the underlying options are exercised and is forfeited if the
options expire unexercised. The Company has charged an expense of $374 (1997:
$264; 1996: $268) relating to compensation on these options. The following
table is a summary of the options granted and outstanding during 1998, 1997
and 1996.

  Of the 401,436 options outstanding, 65,287 options are presently exercisable
at an exercise price of $19.25 and 81,006 are presently exercisable at an
exercise price of $28.75. The remaining options are not presently exercisable
and have a weighted average vesting period of 2.64 years.
 
   The weighted average fair value of options granted during 1998 is $12.21
(1997: $8.18; 1996: $5.85) per share. The fair value of the option grant in
1998 is estimated on the date of grant using the Black-Scholes option pricing
model with the following assumptions: dividend yield of 0% per annum; expected
volatility of 20%; expected life of 7 1/2 years; and a risk free interest rate
of 5.4%.
 
  The Company applies APB Opinion 25 and Related Interpretations in accounting
for the Incentive Plan. Accordingly, a compensation cost has been recognized
based on the intrinsic value of the options at the measurement date. The net
income and earnings per Common Share would have been reduced to the pro forma
amounts indicated below had compensation cost been determined based on the
fair value of the options at the grant date consistent with the method of SFAS
No 123:

purchase options discussed in Note 10, LaSalle Re has entered into the
following transactions and agreements with companies related to the Founding
Shareholders.
 
 (a) Premiums written
 
  During the year ended September 30, 1998, LaSalle Re assumed premiums
written of approximately $16,917 (1997: $21,408; 1996: $24,045) from a ceding
company related to a shareholder of LaSalle Re. In addition, LaSalle Re
assumed premiums totaling $27,190 (1997: $28,450; 1996: $23,577) through
brokers related to a shareholder of LaSalle Re. Brokerage fees incurred in
respect of this business were approximately $2,719 (1997: $2,845; 1996:

Reinsurance balances receivable at the balance sheet date include $8,729
(1997: $13,481) due from such related parties.
 
 (b) Underwriting services
 
  LaSalle Re was party to an underwriting services agreement with CNA Bermuda
during the period from the incorporation of LaSalle Re until September 30,
1998 at which date the agreement was terminated. Under this

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
agreement, LaSalle Re granted CNA Bermuda the authority to provide
underwriting services and to underwrite all classes of insurance and
reinsurance as agents for LaSalle Re. LaSalle Re agreed to pay fees, during
this period, to CNA Bermuda as follows:
 
  Prior to October 1, 1998 but on or after January 1, 1996:
 
    (i) 1.5% of the gross written and collected premium per fiscal year; and
 
    (ii) An underwriting profit commission equal to 4.0% of the aggregate net
  underwriting profits of LaSalle Re, where certain conditions are met.
 
  Prior to January 1, 1996:
 
    (i) 2.0% of the gross written and collected premium per fiscal year, up
  to premium of $150,000 plus 1.5% of the gross written and collected premium
  in excess of $150,000; and
 
    (ii) An underwriting profit commission equal to 2.5% of the aggregate net
  underwriting profits of LaSalle Re, where certain conditions are met.
 
  The Company has incurred $2,535 (1997: $2,526; 1996: $3,081) for
underwriting services provided for the year ended September 30, 1998, of which
$3,658 (1997: $2,903) was payable at September 30, 1998.
 
  The Company has incurred $1,059 (1997: $4,061; 1996: $4,140) for
underwriting profit commission for the year ended September 30, 1998, of which
$Nil (1997: $2,890) was payable at September 30, 1998.
 
  Following the termination of the agreement, all personnel assigned to the
Company by CNA Bermuda became employees of the Company and all underwriting
functions performed by CNA Bermuda are now performed in-house.
 
  Commencing October 1, 1998, LaSalle Re entered into an underwriting support
services agreement with CNA Re Services Company ("CNA Services"). Under this
Agreement, CNA Services will provide certain underwriting support functions to
LaSalle Re but no longer underwrite insurance or reinsurance as agents for
LaSalle Re.
 
  With effect from October 1, 1998:
 
  LaSalle Re has agreed to pay fees to CNA Services as follows:
 
    (i) An annual retainer of $333; and
 
    (ii) An underwriting profit commission equal to 1.67% of the aggregate
  net underwriting profits of LaSalle Re, where certain conditions are met.
 
  The agreement provides for additional fees to be payable if services
provided exceed the retainer. Fees in excess of the retainer are calculated at
competitive commercial daily or hourly rates to be agreed between the parties.
 
 (d) Administrative services
 
  LaSalle Re was party to an agreement with Aon Risk Consultants (Bermuda)
Ltd. ("ARC Bermuda") during the period from the incorporation of LaSalle Re
until September 30, 1997 at which date the agreement was terminated. Under
this agreement, ARC Bermuda performed certain actuarial and administrative
services on behalf of the Company. The management fees payable to ARC Bermuda
were as follows:

  During the year ended September 30, 1998, the Company incurred $44 in
respect of an adjustment to the profit commission accrued for the year ended
September 30, 1997. The Company incurred $6,212 and $6,500 for administrative
services for the years ended September 30, 1997 and 1996 respectively. As of
September 30, 1998, $Nil was payable (1997: $1,987) in respect of services
performed under the agreement.
 
 (e) Investment management services
 
  LaSalle Re is party to an agreement with Aon Advisors (UK) Limited ("Aon
UK") to provide investment management services. Fees are based on a flat fee
structure. Prior to July 1997, fees were based on the average daily balance of
the investment portfolio of the preceding quarter. The average daily balance
was split into various bands, with fees calculated by applying a sliding scale
of basis points to each band.
 
  The Company has incurred $850 (1997: $1,057; 1996: $1,028) for services
provided for the year ended September 30, 1998, of which $215 (1997: $215) was
payable at September 30, 1998.
 
 (f) Claims handling services
 
  LaSalle Re was party to an agreement with Integrated Runoff Insurance
Services Corporation ("IRISC") whereby IRISC performed certain claims handling
services for LaSalle Re. The contract expired December 31, 1996.
 
  The Company has incurred $Nil (1997: $16; 1996: $92) for services provided
for the year ended September 30, 1998. No balance was payable at September 30,
1998 (1997: Nil).
 
 (g) Reinsurance services
 
  Effective January 1, 1997, LaSalle Re was party to a fronting agreement with
Hedge Financial Products, an affiliate of CNA. CNA reinsured LaSalle Re 100%
for the business fronted. LaSalle Re received an administration fee of $63
(1997: $250) for the services provided. The agreement was not renewed on
January 1, 1998.
 
  As at September 30, 1998, no fees were due to the Company (1997: $60).
 
12. CONCENTRATION OF CREDIT RISK
 
  The Company has investment guidelines which restrict investments in
securities below an "AA" grade rating to 20% of the total portfolio and only
10% of the total portfolio can be invested in "BBB" grade rating. The Company
is allowed to invest up to $10,000 in risk based investments and these bonds
may carry a rating below "BBB". In addition, the guidelines restrict
investments in a single issuer to no greater than 5% of the market value of
the portfolio (except for U.S. and U.K. Government issues) and, with respect
to country of issue, to no greater than 25% of the market value of the
portfolio, except for U.S. and supernational borrowers.
 
  A broker, who is unrelated to the Company, arranged more than 17% of the
Company's premiums written for the year ended September 30, 1998 (1997: 15%;
1996: 16%). Another broker, who is unrelated to the Company, arranged more
than 9% of the Company's premiums written for the year ended September 30,
1998 (1997: 10%; 1996: 10%). A broker, who is related to the Company, arranged
17% of the Company's premiums written for the year ended September 30, 1998
(1997: 16%; 1996: 12%). Approximately 14% (1997: 8%; 1996: Nil) of the
Company's gross premiums written are derived from its participation as a
corporate member of Lloyd's.

</TABLE>
 
  The reserves for outstanding losses and loss expenses at September 30, 1998
include an amount of $25,000 in respect of claims arising from Hurricane
Georges. Hurricane Georges occurred in late September and significantly
impacted certain parts of the Caribbean and southern United States. Management
believes that the amount of reserves established will be sufficient to provide
for claims arising from this event. However, the event occurred close to the
Company's fiscal year end and few loss notifications have been received to
date. Given the nature of the event and its proximity to the year end, there
is considerable uncertainty underlying this estimate.
 
  The prior year development in 1998 was primarily due to a loss reported
during the year on a 1996 aggregate stop loss contract. This contract had a
period of 24 months after the expiry of the contract within which to report
losses. Following this notification the Company also established reserves for
the 1997 renewal of this contract. The prior year development in 1997 relates
primarily to an additional liability on Hurricane Fran, which occurred in
September 1996. The amounts incurred in respect of prior year losses in 1996
relate primarily to Hurricanes Luis and Marilyn, which occurred in September
1995. Additional information reported by ceding companies in the months
following the losses necessitated the provision of additional liabilities.
This impact was mitigated by the collection of additional reinstatement
premiums. As at September 30, 1998 the Company's total reserve for incurred
but not reported losses was $52,200 compared to $19,648 at September 30, 1997.
 
14. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK
 
  LaSalle Re has entered into a swap agreement to provide cash flow to a
counterparty in the event of defined earthquake activity in Japan. Receipts to
LaSalle Re which are accounted for as investment income are based on the
notional amount of the swap at 375 basis points. As at September 30, 1998, the
Company had recorded $58 (1997: $Nil) of investment income. The contract
exposes LaSalle Re to a maximum cash outflow of the same notional amount
should the defined seismic event occur. The Company is also exposed to credit
loss in the event of nonperformance by the counterparty to the remittance of
interest payments as required by the swap. The Company does not anticipate
nonperformance by counterparty. At September 30, 1998, the total notional
principal amount of the swap was $3,000 which is supported by a letter of
credit.
 
  The Company's functional currency is the U.S. dollar, however, as the
Company operates internationally, it has exposure to changes in foreign
currency exchange rates. These exposures include net cash inflows on non-U.S.
dollar denominated insurance premiums.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  To manage the Company's exposure to these risks, the Company may enter into
foreign exchange contracts in the major currencies to which the Company is
exposed. These contracts generally involve the exchange of one currency for
another at some future date. The Company has a notional principal amount
outstanding of approximately $5,518 (1997: $Nil; 1996: $25,192) in a contract
to sell foreign currencies. The fair value of these contracts, based on quoted
forward rates available for the maturity of the contracts as at September 30,
1998 is insignificant (1997: $Nil; 1996: ($571). Losses of $Nil (1997: $1,906,
1996: $294) are included in the consolidated statements of operations and
comprehensive income with respect to foreign exchange contracts.
 
  The Company may also enter into foreign exchange contracts to manage the
exposures relating to known reinsurance losses denominated in foreign
currencies. However, no such contracts had been entered into at September 30,
1998.

16. YEAR 2000
 
  The Year 2000 issue faced by the Company revolves around the extent to which
the Company's computer systems and third parties' computer systems (that are
material to the Company's operations such as the computer systems of service
providers, suppliers and brokers) are capable of correctly processing
information relating to dates in and after the Year 2000. The Company has
utilized the services of IBM to perform an assessment and strategy phase for
its Year 2000 issue. This assessment has indicated that the Company's systems,
applications and business interfaces have some degree of Year 2000 date
problems. In addition, the assessment has developed a strategy and series of
plans to implement solutions to the Company's Year 2000 problems. It is
anticipated that 359 effort days will be required and estimated costs are
currently budgeted at approximately $300 but are subject to change due to the
cost of external resources. A target date of March 31, 1999 has been set for
full Year 2000 compliance, however, this may not be achieved as there are a
number of external factors which are beyond the Company's control. The Company
intends to retain the services of IBM who will take responsibility for the co-
ordination of the project, however, overall responsibility for Year 2000
compliance remains with the Company.
 
17. CREDIT FACILITY
 
  The Company has in place a $100 million committed line of credit from a
syndicate of banks. The proceeds from the credit facility may only be used to
buy preferred shares of LaSalle Re that, in turn, may use the proceeds of such
purchase to meet current cash requirements. The facility matures December 1,
2000, and is secured by a pledge ("legal mortgage") of all the capital stock
of LaSalle Re held by the Company, including any preferred shares that may be
issued by LaSalle Re to the Company. As at September 30, 1998, the facility
had not been utilized.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The line of credit contains various covenants, including limitations on
incurring additional indebtedness; restrictions on the sale or lease of assets
not in the ordinary course of business; maintenance of a ratio of consolidated
total debt to consolidated tangible net worth of no more than 0.40 to 1.00;
maintenance of tangible net worth at the end of each fiscal year of the
greater of $300 million or 70% of net premiums written; maintenance of
statutory capital of LaSalle Re of at least $300 million, increasing to $350
million at the end of calendar year 1998 and $400 million at the end of
calendar year 1999 and thereafter; and maintenance of a ratio of net premiums
written to statutory capital at the end of any fiscal quarter for the four
fiscal quarters then ended of no more than 1.00 to 1.00 in each case. The
Company may pay dividends and make other restricted payments so long as, after
giving effect to such restricted payments, no event of default has occurred.
Dividends are limited to 50% of consolidated net income for its immediately
preceding fiscal year less amounts paid on the Series A preferred shares. In
order for the Company to pay dividends in excess of 50% of consolidated net
income, the Company would have to renegotiate certain terms of its credit
facility. As of September 30, 1998, the credit facility had not been utilized
and the Company was in compliance with all covenants under the facility.
 
18. STATUTORY DATA
 
  The Company's ability to pay dividends is subject to certain regulatory
restrictions on the payment of dividends by LaSalle Re. Under the Act, LaSalle
Re is required to prepare statutory financial statements and to file in
Bermuda a statutory financial return. LaSalle Re is required to maintain
certain measures of solvency and liquidity.
 
  The statutory capital and surplus of LaSalle Re at September 30, 1998 was
approximately $506,000 (1997: $490,000) and the minimum required statutory
capital and surplus required by its license as a Class 4 insurer was $100,000
(1997: $100,000).
 
  In this regard, the declaration of dividends from retained earnings and
distributions from additional paid in capital is limited to the extent that
the above requirements are met. At September 30, 1998, there were no
restrictions on the distribution of retained earnings.

20. TAXATION
 
  Under current Bermuda law, the Company is not required to pay any taxes in
Bermuda on either income or capital gains. The Company has received an
undertaking from the Minister of Finance in Bermuda that will exempt the
Company from taxation until the year 2016 in the event of any such taxes being
imposed.
 
  Other than with respect to its Lloyd's business, the Company does not
consider itself to be engaged in a trade or business in the United States and
accordingly does not expect to be subject to United States income taxes.
LaSalle Re Corporate Capital Ltd. is a corporate member of Lloyd's. Pursuant
to a Closing Agreement between Lloyd's and the IRS, LaSalle Re Corporate
Capital Ltd. will be treated as engaged in business in the U.S. and is subject
to U.S. corporate income tax on its net income from U.S. sources.
 
  LaSalle Re Corporate Capital Ltd. is also subject to U.K. corporation tax,
with the assessment made at the end of thirty six months. Given the inherent
uncertainty in the results of the supported syndicates, the Company has not
included a deferred tax asset or liability in these financial statements.

hereinafter referred to as the "Underwriting Services Agreement"), CNA BERMUDA
has provided underwriting and marketing services and has underwritten all
classes of insurance and reinsurance as agent for LASALLE;

  WHEREAS, the parties hereto have agreed that the underwriting and marketing
services heretofore performed by CNA BERMUDA on behalf of LASALLE shall
henceforth be performed by LASALLE directly, with CRSC, through itsself and its
affiliates, providing certain underwriting support services as requested by
LASALLE;

  WHEREAS, the parties hereto also desire to reaffirm the strategic alliance and
community of interest between LASALLE and the CNA Insurance Group ("CNA"), which

<PAGE>
 
I.     TERMINATION OF UNDERWRITING SERVICES AGREEMENT.

       The parties agree that the Underwriting Services Agreement shall
       terminate as of the close of business on September 30, 1998, subject to
       the following provisions:

       A.     LASALLE's payment obligations under Section III of the
              Underwriting Services Agreement shall continue, subject to the
              following modifications:

              (1)    For purposes of this Section I(A), the term "Underwriting
                     Year" shall have the meaning set forth in Section III(A)(1)
                     of the Underwriting Services Agreement and the term "1998
                     Underwriting Year" shall mean the Underwriting Year
                     beginning on January 1, 1998 and ending on December 31,
                     1998.

              (2)    No payments shall be due pursuant to Section III(B)(1) of
                     the Underwriting Services Agreement with respect to any
                     gross premium written after September 30, 1998.

              (3)    No payments shall be due pursuant to Section III(B)(2) or
                     Section III(C) of the Underwriting Services Agreement with
                     respect to any Underwriting Year that begins after December
                     31, 1998.

              (4)    All calculations of payments due pursuant to Section
                     III(B)(2) or Section III(C) of the Underwriting Services
                     Agreement with respect to the 1998 Underwriting Year shall
                     be multiplied by .75 in order to take account of the fact
                     that the Underwriting Services Agreement was in effect for
                     only 9 months of the 1998 Underwriting Year.

       B.     The provisions of Section VII(D) of the Underwriting Services
              Agreement shall not be applicable, but the provisions of Section
              VII(E) of the Underwriting Services Agreement shall continue in
              effect until payment in full is made thereunder.

II.    TERM.

       This Agreement shall be effective as of the date hereof (the "Effective
       Date") and shall terminate at the close of business on September 30, 2001
       unless terminated earlier pursuant to Section V hereof.

III.      DUTIES OF CRSC AND CNA BERMUDA.

       A.     CNA BERMUDA agrees that it shall use its best efforts to
              facilitate a smooth transition in the carrying on of LASALLE's
              underwriting operations, including taking all steps necessary to
              enable all employees of CNA BERMUDA who have performed services
              for LASALLE pursuant to the Underwriting Services Agreement to
              become employees of LASALLE on the Effective Date.

       B.     Beginning on the Effective Date and continuing throughout the term
              of this Agreement, CRSC and CNA BERMUDA (together, the "CNA
              Parties") shall provide such underwriting support services to
              LASALLE as LASALLE may reasonably request.  Underwriting support
              services shall include:

              (1)    assigning underwriting personnel to assist LASALLE's
                     underwriting staff on a temporary basis as reasonably
                     requested by LASALLE;

              (2)    assisting LASALLE with actuarial, financial and statistical
                     analysis and reporting;

              (3)    providing support to LASALLE on data processing and other
                     technical matters;

              (4)    providing LASALLE with access to the CNA Parties'
                     reinsurance underwriting database and technology as
                     pertinent to LASALLE's business;

              (5)    advising LASALLE on insurance industry customs and
                     practices;

              (6)    providing advice to LASALLE's human resources department;
                     and

              (7)    any other services reasonably requested by LASALLE.

       C.     For services rendered hereunder, LASALLE shall pay CNA BERMUDA,
              for each Fiscal Year (as hereinafter defined) that this Agreement
              shall be in effect, an annual retainer of $US 333,333.33.  Such
              retainer shall be paid quarterly in arrears throughout the term of
              this Agreement and shall be credited against CRSC's charges for
              consulting services rendered hereunder (at a competitive
              commercial daily or hourly rate to be agreed to between the

VIII.  NON-EXCLUSIVITY.

              This Agreement shall not in any way prevent the CNA Parties from
              performing for other insurers services of the type described
              herein, provided that the CNA Parties faithfully perform their
              obligations under this Agreement and that the performance of
              services for others does not create any conflict of interest. The
              CNA Parties agree, however, that they shall promptly notify
              LASALLE in writing, as soon as reasonably practicable but in any
              event prior to execution, of any arrangement entered into by

              of the CNA Parties may assign, pledge, hypothecate, transfer,
              delegate or subcontract this Agreement or any of its rights,
              benefits or obligations hereunder, in whole or in part, whether by

       representatives or assigns of the parties hereto.

XI.    NO WAIVER.

       The failure of any party at any time to require another party's strict
       performance of any particular obligation under this Agreement shall not
       affect such party's right to require strict performance of that
       obligation in the future.  Any waiver by any party of any breach of any
       provision hereof shall not be construed as a waiver of any continuing or
       succeeding breach of such provision, or a waiver or modification of the

     WHEREAS, the parties desire to enter into this Agreement pertaining to the

     1.  Performance of Services.  The Executive's employment with the Company
         -----------------------

(a)  Subject to the provisions of this Agreement, the Company hereby agrees to
     employ the Executive as the President and Chief Operating Officer of the

(c)  The Executive agrees that he shall perform his duties faithfully and
     efficiently subject to the directions of the Board of Directors (the
     "Board") and the Chief Executive Officer (the "CEO") of the Company.  The
     Executive's duties may include providing services for the Company, the
     Holding Company, and the Subsidiaries (as defined below), as determined by
     the CEO; provided that the Executive shall not, without his consent, be
     assigned tasks that would be inconsistent with his position at the Company.
     The Executive will have such authority and power as are inherent to the
     undertakings applicable to his position and necessary to carry out his
     responsibilities and the duties required of him hereunder.

(d)  While the Executive is employed by the Company, he shall be subject to the
     duties that reasonably apply to the Company's officers and employees
     (including, without limitation, the duty of loyalty to the Company).

     other than those required under this Agreement, including the supervision
     of his personal investments, and activities involving professional,
     charitable, educational, religious and similar types of organizations,
     speaking engagements, membership of the boards of directors of other
     organizations, and similar type of activities, to the extent that such
     other activities do not inhibit or prohibit the performance of the
     Executive's duties under this Agreement, or conflict in any material way
     with the business of the Company, the Holding Company, or any Subsidiary;
     provided, however, that except as otherwise expressly provided in this
     Agreement, the Executive shall not serve on the board of any business, or
     hold any position with any business without the consent of the Board and
     the CEO of the Company.

(g)  The Executive will be required to maintain a residence in Bermuda while
     employed by the Company.

(h)  The Company will use its reasonable best efforts to maintain a Bermuda work
     permit for the Executive.  The Executive shall cooperate with the Company
     and the appropriate authorities in maintaining such permit.  The
     Executive's employment by the Company is conditioned upon the Company's
     ability to keep current all required work permits, and except as provided
     in this paragraph 1(h), the Company shall have no further obligation to the
     Executive if, after employing its reasonable best efforts, it is unable to
     maintain such permits.  If despite the Company's best efforts to maintain
     the Bermuda work permit, the work permit is terminated or revoked by the
     Government of Bermuda through no fault of the Executive, then the Executive
     shall be deemed to have received written notice from the Company that his
     Date of Termination is the date on which the termination or revocation of
     his or her work permit is effective, and the Executive shall be entitled to
     the benefits provided for Termination by the Company under Section 3(g). In
     addition, the Company shall reimburse the Executive for reasonable costs
     actually incurred by the Executive and the members of his or her immediate
     family to relocate to the nation in which the Executive maintains
     citizenship; provided, however, that such reimbursement shall be made only
     if such relocation occurs within a reasonable time following such Date of
     Termination.  The reasonableness of the cost and time of relocation shall
     be determined by the Board of Directors of the Company.

(i)  Subject to the provisions of this Agreement, the Executive shall not be
     required to perform services under this Agreement during any period that he
     is Disabled.  The Executive shall be considered "Disabled" during any
     period in which he has a physical or mental disability which renders him
     incapable, after reasonable accommodation, of performing his duties under
     this Agreement.  In the event of a dispute as to whether the Executive is
     Disabled, the Company may refer the same to a licensed practicing

                                       2

     physician of the Company's choice, and the Executive agrees to submit to
     such tests and examination as such physician shall deem appropriate.

(j)  The "Agreement Term" shall be the period beginning on the Effective Date
     and ending on the second anniversary of the Effective Date; provided,
     however, that beginning on the first anniversary of the Effective Date,
     such Agreement Term shall automatically be renewed daily, such that at any
     time on or after the first anniversary of the Effective Date, the remaining
     term shall equal one year.  However, such additional day-to-day renewals
     may be terminated by either party be delivering written notice of such
     termination to the other party, in accordance with the requirements of
     paragraph 18.  The cessation of the automatic renewals shall be effective
     on the date such written notice is deemed to be given to the other party in
     accordance with paragraph 18, such that the Agreement term shall end on the
     one-year anniversary of the date such written notice is deemed given to the
     other party.  For purposes of this Agreement, a Notice of Termination, as
     described in paragraph 3(i), shall be deemed to be a notice to terminate
     day-to-day renewals.

(k)  For purposes of this Agreement, the term "Subsidiary" shall mean any
     company (regardless of whether incorporated) during any period in which 50%
     or more of the total combined voting power of all classes of stock (or
     other ownership interest) entitled to vote is owned, directly or
     indirectly, by the Company.

      2.  Compensation.  Subject to the provisions of this Agreement, during the
          ------------                                                          
Agreement Term, while he is employed by the Company, the Company shall
compensate the Executive for the Executive's services as follows:

(a)  Salary.   The Executive shall receive, for each 12-consecutive month period
     ------                                                                     
     beginning on the Effective Date and each anniversary thereof, in
     substantially equal monthly or more frequent installments, an annual base
     salary of $400,000 (the "Salary").  In no event shall the Salary of the
     Executive be reduced to an amount that is less than the amount specified in
     this paragraph (a), or to an amount that is less than the amount that he
     was previously receiving, except to the extent that reductions of the same
     percentage are being made at the same time to the salaries of all other
     Company officers in the corporate office at or above the vice-president
     level, and such Salary shall be restored to its prior level when, and to
     the same extent, as the restoration that applies to the other officers.

(b)  Bonus.  The Executive shall be entitled to receive bonuses from the Company
     -----                                                                      
     in accordance with the provisions of Exhibit A, which is attached to and
     forms a part of this Agreement.

(c)  Disability.  The Executive shall receive from the Company disability income
     ----------                                                                 
     replacement coverage which will provide for replacement of income at a
     commercially reasonable rate during any period in which the Executive is
     Disabled if the disability arose during the Agreement Term and prior to the
     Executive's Date of Termination.  During any period while the Executive is
     Disabled, and is otherwise entitled to receive Salary under this Agreement,
     any Salary payments to the Executive shall be reduced by the amount of any

                                       3
<PAGE>
 
     benefits paid for the same period of time under the Company's disability
     income replacement coverage.

(d)  Pension.  The Company will provide the Executive with a defined
     -------                                                        
     contribution savings plan, into which the Company will make a contribution
     for each fiscal year equal to 10% of the Salary paid to the Executive for
     such fiscal year.  The plan will also provide that the Executive may make
     annual contributions equal to or less than the Company's contribution.

(e)  Automobile. The Company will provide the Executive with an allowance toward
     ----------                                                                 
     the cost of an automobile in Bermuda, the amount of which will be approved
     by the CEO.  The Company will assume responsibility for the cost of
     insurance, maintenance and similar items.  The Executive's personal use of
     the automobile will be permitted.  This perquisite shall be governed by the
     rules and limitations set down from time to time by the Company.

(f)  Club.  The Company will reimburse the Executive for periodic dues for his
     ----                                                                     
     membership in clubs located in Bermuda in an amount not to exceed $2,400
     per fiscal year.  The Company will not reimburse initiation fees for club
     membership under this Agreement, in light of reimbursements made by the
     Company to the Executive's prior employer with respect to initiation fees
     for club membership for the period during which the Executive performed
     services for the Company but was employed by the prior employer.

(g)  Housing/Living Allowance.  The Company shall provide the Executive with a
     ------------------------                                                 
     housing and living expense allowance at the annual rate of $120,000 for the
     Agreement Term, with such allowance to be payable to the Executive in
     monthly instalments.

(h)  Tax, Accounting and Financial Planning.  The Company will reimburse the
     --------------------------------------                                 
     Executive for reasonable expenses, not to exceed $5,000 per fiscal year,
     for tax, accounting, and financial planning services.

(i)  Other Benefits.  Except as otherwise specifically provided to the contrary
     --------------                                                            
     in this Agreement, the Executive shall be provided with the welfare
     benefits and other fringe benefits to the same extent and on the same terms
     as those benefits are provided by the Company from time to time to the
     Company's other senior management employees. However, the Company shall not
     be required to provide a benefit or perquisite under this paragraph 2(i) if
     such benefit or perquisite would duplicate (or otherwise be the same type
     as) a benefit or perquisite specifically required to be provided under
     another provision of this Agreement.

(j)  Expenses.  Upon approval by the CEO, the Company will reimburse the
     --------                                                           
     Executive for reasonable expenses for entertainment, traveling, meals,
     lodging and similar items in promoting the Company's business which the
     Executive documents on a form used by the Company to report business
     expenses.

     ---------------                                                          
     in commercially reasonable amounts (as reasonably determined by the Board),
     and the Executive shall be covered under such insurance to the same extent
     as other senior management employees of the Company.  The Executive shall
     be eligible for indemnification by the Company under the Company's bye-laws
     as currently in effect. The Company agrees that it shall not take any
     action that would impair the Executive's rights to indemnification under
     the Company's bye-laws, as currently in effect.

(l)  Holiday/Vacation.  The Executive shall be subject to the holiday and
     ----------------                                                    
     vacation policy that applies to other senior executives of the Company.

(m)  Dollar Amounts.  As used in this Agreement, "dollars" or numbers preceded
     --------------                                                           
     by the symbol "$" shall mean amounts in United States Dollars.

     3.  Termination.  The Executive's employment during the Agreement Term may
         -----------       
be terminated by the Company or the Executive without any breach of this
Agreement only under the circumstances described in paragraphs 3(a) through
3(g):

(a)  Death.  The Executive's employment will terminate upon his death.
     -----                                                            

(b)  Permanently Disabled.  The Company may terminate the Executive's employment
     --------------------                                                       
     if he is Permanently Disabled.  "Permanently Disabled" means that the
     Executive is eligible for benefits under the Company's long-term disability
     plan.

(c)  Cause.  The Company may terminate the Executive's employment at any time
     -----                                                                   
     for Cause. "Cause" shall mean:

     (i)    the wilful and continued failure by the Executive to substantially
            perform his duties with the Company (other than any such failure
            resulting from the Executive's being Disabled), within a reasonable
            period of time after a written demand for substantial performance is
            delivered to the Executive by the CEO, which demand specifically
            identifies the manner in which the CEO believes that the Executive
            has not substantially performed his duties;

     (ii)   the wilful engaging by the Executive in conduct which is
            demonstrably and materially injurious to the Company or the Holding
            Company, monetarily or otherwise; or

     (iii)  the engaging by the Executive in egregious misconduct involving
            serious moral turpitude to the extent that, in the reasonable
            judgment of the CEO, the Executive's credibility and reputation no
            longer conform to the standard of the Company's executives.

     For purposes of this Agreement, no act, or failure to act, on the
     Executive's part shall be deemed "wilful" unless done, or omitted to be
     done, by the Executive not in good faith

                                       5
<PAGE>
 
     and without reasonable belief that the Executive's action or omission was
     in the best interest of the Company or the Holding Company.

(d)  Constructive Discharge.  If the Executive (i) provides written notice to
     ----------------------                                                  
     the Company of the occurrence of a material breach of this Agreement by the
     Company, which specifically identifies the manner in which the Executive
     believes that the breach has occurred; (ii) the Company fails to correct
     such breach within a reasonable time after such notice; and (iii) the
     Executive resigns within the 60-day period following the occurrence of such
     breach, then the Executive shall be considered to have been constructively
     discharged.

(e)  Resignation by Executive.  The Executive may resign for any reason by
     ------------------------                                             
     giving the Company ninety (90) days prior written notice, except the
     Executive will be treated as having resigned under this paragraph 3(e) only
     if he has not been constructively discharged under paragraph 3(d).

(f)  Mutual Agreement. This Agreement may be terminated at any time by the
     ----------------                                                     
     mutual agreement of the parties.  Any termination of the Executive's
     employment by mutual agreement of the parties will be memorialized by an
     agreement which is reduced in writing and signed by the Executive and the
     CEO or other duly appointed officer of the Company.

(g)  Termination by Company.  The Company may terminate the Executive's
     ----------------------                                            
     employment at any time for any reason by giving the Executive prior written
     notice, except the Executive's employment will not be treated as having
     been terminated under this paragraph 3(g) if the termination is for reasons
     of being Permanently Disabled or for Cause.

(h)  Date of Termination.  "Date of Termination" means the last day the
     -------------------                                               
     Executive is employed by the Company, provided that the Executive's
     employment is terminated in accordance with the foregoing provisions of
     this paragraph 3.

(i)  Notice of Termination. Any termination of the Executive's employment by the
     ---------------------                                           
     Company or the Executive (other than a termination pursuant to paragraph
     3(a) or paragraph 3(f)) must be communicated by a written Notice of
     Termination to the other party hereto. For purposes of this Agreement, a
     "Notice of Termination" means a dated notice which indicates the specific
     termination provision in this Agreement relied on and which sets forth in
     reasonable detail the facts and circumstances, if any, claimed to provide a
     basis for termination of the Executive's employment under the provision so
     indicated.

     4.   Rights Upon Termination.  This paragraph 4 describes the payments and
          -----------------------                                              
benefits to be provided to the Executive after his Date of Termination:

(a)  Payment of Previously Earned Amounts.  The Executive shall receive payment
     ------------------------------------                                      
     of accrued but unpaid Salary, vacation pay and, if expressly provided for
     in paragraph 4(d),

                                       6
<PAGE>
 
     a pro rata portion of his bonus (if any), in each case for the period
     ending with the Executive's Date of Termination.

(b)  No Severance Payments.  If the Executive's Date of Termination occurs
     ---------------------                                                
     during or after the end of the Agreement Term, or because of (i) the
     Executive's death, (ii) his being Permanently Disabled (paragraph 3(b)),
     (iii) his termination for Cause (paragraph 3(c)), or (iv) his resignation
     (paragraph 3(e)), then, except as otherwise expressly provided for in this
     Agreement, no payments shall be due to the Executive under this Agreement
     for periods after the Date of Termination.

(c)  Salary Continuation.  If the Executive's Date of Termination occurs during
     -------------------                                                       
     the Agreement Term because of (i) his discharge by the Company for reasons
     other than Cause (described in paragraph 3(c)), or (ii) his constructive
     discharge (described in paragraph 3(d)), the Executive shall continue to
     receive Salary payments (at the rate in effect on the Date of Termination)
     in monthly or more frequent instalments through the earliest of: (i) the
     last day of the Agreement Term; (ii) the date of the Executive's death, or
     (iii) the date, if any, of the breach by the Executive of the non-
     competition requirements of paragraph 7, the confidentiality requirements
     of paragraph 8 or the non-disparagement requirements of paragraph 9.

(d)  Pro rata Bonus.  Except as otherwise provided in this paragraph 4(d), the
     --------------                                                           
     Executive shall not receive a bonus for the fiscal year in which the
     Executive's Date of Termination occurs.  If the Executive's Date of
     Termination occurs during the Agreement Term as a result of (i) the
     Executive's death (ii) his being Permanently Disabled (paragraph 3(b)),
     (iii) his discharge by the Company for reasons other than Cause (described
     in paragraph 3(c)), or (iv) his constructive discharge (described in
     paragraph 3(d)), the Executive shall receive a pro rata portion of the
     bonus which would have been paid pursuant to Exhibit A for the fiscal year
     in which the Executive's Date of Termination occurs.  Such portion, if any,
     shall be calculated for the period ending on the Date of Termination and
     shall be paid to the Executive (or his estate) within a reasonable period
     of time after the Company calculates the bonus amount, if any, for all
     employees for the fiscal year.

(e)  Housing/Living Expenses, Medical Benefits.  If the Executive is entitled to
     -----------------------------------------                                  
     Salary Continuation payments pursuant to paragraph 4(c), the Executive
     shall receive a housing and living expense allowance (described in
     paragraph 2(g)) and may continue to participate in the medical and dental
     plans in which he participated on the day before his Date of Termination
     through the earlier of: (i) the last day for which the Executive receives
     Salary Continuation payments pursuant to paragraph 4(c); or (ii) three (3)
     months after the Executive's Date of Termination.  Participation in the
     medical and dental plans is subject to the Executive's payment of the
     applicable employee portion of the monthly premium cost, if any.  If the
     Company ceases offering the medical and dental plans in which the Executive
     participated on the day before his Date of Termination to Company employees
     during this time, the Executive may elect to participate in any other
     medical or dental plan offered by the Company to its employees, provided
     however, that the Executive shall be responsible for paying the applicable
     employee portion of the monthly premium cost.

                                       7
<PAGE>
 
(f)  Other Programs.  No benefits shall be payable to the Executive under any
     --------------                                                          
     other severance pay arrangement or similar arrangement maintained by the
     Company or any Subsidiary. Except as otherwise expressly provided in this
     Agreement, no other payments or benefits shall be due to the Executive
     following the Date of Termination (except as otherwise specifically
     provided under the terms of an employee benefit plan or arrangement).

     5.   Duties on Termination.  Subject to the provisions of this Agreement,
          ---------------------                                               
during the period beginning on the date of delivery of a Notice of Termination,
and ending on the Date of Termination, the Executive shall continue to perform
his duties as set forth in this Agreement, and shall also perform such services
for the Company and the Holding Company as are necessary and appropriate for a
smooth transition to the Executive's successor, if any. Notwithstanding the
foregoing provisions of this paragraph 5, the Company may suspend the Executive
from performing his duties under this Agreement following the delivery of a
Notice of Termination providing for the Executive's resignation, or delivery by
the Company of a Notice of Termination providing for the Executive's termination
of employment for any reason; provided, however, that during the period of
suspension (which shall end on the Date of Termination), the Executive shall
continue to be treated as employed by the Company for other purposes, and his
rights to compensation or benefits shall not be reduced by reason of the
suspension.

     6.   Set-Off.  If the Executive's employment with the Company is terminated
          -------                                                               
for any reason and, under the terms of this Agreement, the Executive is
otherwise entitled to receive Salary and bonus payments, such payments will be
reduced by the amount of any salary and bonus payments the Executive receives in
connection with other employment.

     7.   Non-competition.  While the Executive is employed by the Company, and
          ---------------                                                      
during the Non-Competition Period (as defined below), the Executive agrees that
he will not directly or indirectly perform services in an underwriting-related
or consulting-related position in Bermuda for a direct competitor of the
Company.  A related position shall include, but is not limited to, a chief
operating officer or executive vice president.

For purposes of this paragraph 7:

     "Non-Competition Period" shall be determined as follows:

     (1)  If the Executive's Date of Termination occurs under circumstances
          other than those described in paragraph 3(d) (relating to constructive
          discharge) or paragraph 3(g) (relating to certain terminations by the
          Company), the Non-Competition Period shall be the period beginning on
          the Date of Termination, and ending on the twenty-four-month (24)
          anniversary of the Date of Termination.

     (2)  If the Executive's Date of Termination occurs under circumstances
          described in paragraph 3(d) (relating to constructive discharge) or
          paragraph 3(g) (relating to certain terminations by the Company), the
          Non-Competition Period shall be the period beginning on the Date of
          Termination, and ending

                                       8
<PAGE>
 
          on the earlier to occur of the last day of the Agreement Term or the
          twenty-four-month (24) anniversary of the Date of Termination.
          However, under this paragraph (B), the Company, in its discretion, by
          notice provided to the Executive not later than fifteen (15) days
          after the Date of Termination, may extend the Non-Competition Period
          beyond the end of the Agreement Term, to a date specified in such
          notice (but not later than the twenty-four-month anniversary of the
          Date of Termination), but only if the Company agrees to provide the
          salary continuation payments described in paragraph 4(c) during such
          Non-Competition Period.

Nothing in this paragraph 7, paragraph 8 or paragraph 9 shall be construed as
limiting the Executive's duty of loyalty to the Company while he is employed by
the Company or any other duty he may otherwise have to the Company while he is
employed by the Company.

     8.   Confidential Information.  Except as may be required by the lawful 
          ------------------------       
order of a court or agency of competent jurisdiction, or except to the extent
that the Executive has express authorization from the Company, the Executive
agrees to keep secret and confidential indefinitely all non-public information
(including, without limitation, information regarding litigation and pending
litigation) concerning the Company, the Holding Company, and the Subsidiaries
which was acquired by or disclosed to the Executive during the course of his
employment with the Company, or during the course of his consultation with the
Company following his termination of employment (regardless of whether
consultation is pursuant to paragraph 10), and not to disclose the same, either
directly or indirectly, to any other person, firm, or business entity, or to use
it in any way. To the extent that the Executive obtains information on behalf of
the Company, the Holding Company, or any of the Subsidiaries that may be subject
to attorney-client privilege as to the Company's attorneys, the Executive shall
take reasonable steps to maintain the confidentiality of such information and to
preserve such privilege. Nothing in the foregoing provisions of this paragraph 8
shall be construed so as to prevent the Executive from using, in connection with
his employment for himself or an employer other than the Company, the Holding
Company, or any of the Subsidiaries, knowledge which was acquired by him during
the course of his employment with the Company, the Holding Company, and the
Subsidiaries, and which is generally known to persons of his experience in other
companies in the same industry.

     9.   Non-Disparagement.  The Executive agrees that, while he is employed by
          -----------------                                                     
the Company, and after his Date of Termination, he shall not make any false,
defamatory or disparaging statements about the Company, the Holding Company, the
Subsidiaries, or the officers or directors of the Company, the Holding Company,
or the Subsidiaries that are reasonably likely to cause material damage to the
Company, the Holding Company, the Subsidiaries, or their officers or directors.
While the Executive is employed by the Company, and after his Date of
Termination, the Company agrees, on behalf of itself, the Holding Company, and
the Subsidiaries, that neither the officers nor the directors of the Company,
the Holding Company, or the Subsidiaries shall make any false, defamatory or
disparaging statements about the Executive that are reasonably likely to cause
material damage to Executive.

                                       9

     10.  Defense of Claims.  The Executive agrees that, for the period 
          -----------------        
beginning the Effective Date, and continuing for a reasonable period after the
Executive's termination of employment with the Company, the Executive will
cooperate with the Company, the Holding Company and the Subsidiaries in defense
of any claims that may be made against the Company, the Holding Company and the
Subsidiaries, and will cooperate with the Company, the Holding Company or the
Subsidiaries in the prosecution of any claims that may be made by the Company,
the Holding Company or the Subsidiaries, to the extent that such claims may
relate to services performed by the Executive for the Company. The Executive
agrees to promptly inform the Company if he becomes aware of any lawsuits
involving such claims that may be filed against the Company, the Holding Company
or the Subsidiaries. The Company agrees to reimburse the Executive for all of
the Executive's reasonable out-of-pocket expenses associated with such
cooperation, including travel expenses. For periods after the Executive's
employment with the Company terminates, the Company agrees to provide reasonable
compensation to the Executive for such cooperation. The determination of the
reasonableness of such compensation shall take into account information provided
to the Company by the Executive or otherwise known to the Company, which may
include, without limitation, (a) the Executive's rate of compensation at the
time he ceased employment with the Company, and whether he is then receiving
other compensation payments from the Company; (b) the Executive's rate of
compensation at the time of such cooperation; (c) the amount of time required of
the Executive for such cooperation; (d) difficulty of the issues as to which the
cooperation is required; (e) the amount of inconvenience to the Executive
resulting from such cooperation (including consideration of factors such as the
amount of travel required of the Executive, the effect on other commitments of
the Executive, and the amount of advance notice provided to the Executive); and
(f) whether such cooperation would be legally required in the absence of the
requirements of this paragraph 10. The Executive also agrees to promptly inform
the Company if he is asked to assist in any investigation of the Company, the
Holding Company or the Subsidiaries (or their actions) that may relate to
services performed by the Executive for the Company, regardless of whether a
lawsuit has then been filed against the Company, the Holding Company or the
Subsidiaries with respect to such investigation.

     11.  Remedies.  The Executive acknowledges that the Company or the Holding
          --------                                                             
Company would be irreparably injured by a violation of paragraph 7, paragraph 8,
or paragraph 9, and he agrees that the Company, in addition to any other
remedies available to it for such breach or threatened breach, shall be entitled
to a preliminary injunction, temporary restraining order, or other equivalent
relief, restraining the Executive from any actual or threatened breach of either
paragraph 7, paragraph 8 or paragraph 9.  The Company acknowledges that the
Executive would be irreparably injured by a violation of paragraph 9, and the
Company agrees that the Executive, in addition to any other remedies available
to him for such breach or threatened breach, shall be entitled to a preliminary
injunction, temporary restraining order, or other equivalent relief, restraining
the Company from any actual or threatened breach of paragraph 9.  If a bond is
required to be posted in order for the Company or the Executive to secure an
injunction or other equitable remedy, the parties agree that said bond need not
be more than a nominal sum.

     12.  Nonalienation.  The interests of the Executive under this Agreement 
          -------------  
are not subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, attachment, or garnishment by creditors of the
Executive or the Executive's beneficiary.

     13.  Amendment.  This Agreement may be amended or canceled only by mutual
          ---------                                                           
agreement of the parties in writing without the consent of any other person. So
long as the Executive lives, no person, other than the parties hereto, shall
have any rights under or interest in this Agreement or the subject matter
hereof.

     14.  Applicable Law.  The provisions of this Agreement shall be construed 
          --------------          
in accordance with the laws of Bermuda, without regard to the conflict of law
provisions of any jurisdiction. All disputes shall be arbitrated or litigated
(whichever is applicable) in Bermuda.

     15.  Severability.  The invalidity or unenforceability of any provision of
          ------------                                                         
this Agreement will not affect the validity or enforceability of any other
provision of this Agreement, and this Agreement will be construed as if such
invalid or unenforceable provision were omitted (but only to the extent that
such provision cannot be appropriately reformed or modified).

     16.  Waiver of Breach.  No waiver by any party hereto of a breach of any
          ----------------                                                   
provision of this Agreement by any other party, or of compliance with any
condition or provision of this Agreement to be performed by such other party,
will operate or be construed as a waiver of any subsequent breach by such other
party or any similar or dissimilar provisions and conditions at the same or any
prior or subsequent time.  The failure of any party hereto to take any action by
reason of such breach will not deprive such party of the right to take action at
any time while such breach continues.

     17.  Successors.  This Agreement shall be binding upon, and inure to the
          ----------

binding and non-appealable arbitration in Bermuda by three arbitrators.  Except

                                   EXHIBIT A
                                   ---------


                               BONUS COMPUTATION
                               -----------------

     A-1.  Purpose.  This Exhibit A is attached to and forms a part of the
           -------                                                        
employment agreement (the "Agreement") between Guy Hengesbaugh (the "Executive")
and LaSalle Re Limited (the "Company").  The purpose of this Exhibit A is to set
forth the terms of the bonus program described in paragraph 2(b) of the
Agreement.

     A-2.  Guidelines.  The bonus shall be determined in accordance with the
           ----------                                                       
following guidelines:

 .    A discretionary bonus may be awarded annually by the Board of the Company
     after considering the recommendation of the CEO of the Company.

 .    A non-discretionary bonus shall be earned and paid annually based upon the
     Company's Return on Equity (defined below) achieved for each fiscal year of
     the Company, while the Executive is employed by the Company.

 .    The non-discretionary annual bonus calculation will be based on the
     Company's Return on Equity earned each year. If the Company's Return on
     Equity for any year exceeds 15%, the bonus will be paid according to the
     following formula: 

     .    For each 1% improvement in Return on Equity above 15%, an amount equal
          to 10.0 % of The Executive's Salary will be paid.

     .    For each 1% improvement in Return on Equity above 22.5%, an amount
          equal to 15.0 % of The Executive's Salary will be paid.

     .    For Return on Equity results between whole percentages (but above
          15%), the percentage of Salary awarded will be increased by
          interpolation.

     .    The "Return on Equity" for any fiscal year shall be equal to the net
          income of the Company for the fiscal year, divided by shareholders'
          equity at the beginning of the period (as determined on the basis of
          U.S. generally accepted accounting principles). For purposes of this
          calculation any unrealized appreciation or depreciation of the
          Company's investments shall be disregarded (both as to the numerator
          and the denominator). Payments made to CNA Financial Corporation or
          its affiliates under the Underwriting Support Services Agreement will
          not reduce net income in determining the Return on Equity.

                             EMPLOYMENT AGREEMENT
                             --------------------

   THIS AGREEMENT, made and entered into as of October 1, 1998 (the "Effective
Date"), by and between Andrew Cook (the "Executive") and LaSalle Re Limited (the
"Company");

                               WITNESSETH THAT:
                               --------------- 

     WHEREAS, the parties desire to enter into this Agreement pertaining to the
continued employment of the Executive by the Company;

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth below, it is hereby covenanted and agreed by the Executive and the Company
as follows:

     1.   Performance of Services.  The Executive's continued employment with 
          -----------------------   
the Company shall be subject to the following:

(a)  Subject to the provisions of this Agreement, the Company hereby agrees to
     continue to employ the Executive as the Senior Vice President, Chief
     Financial Officer and Treasurer of the Company and LaSalle Re Holdings
     Limited (the "Holding Company") during the Agreement Term (as defined
     below), and the Executive hereby agrees to remain in the employ of the
     Company during the Agreement Term.

(b)  During the Agreement Term, while the Executive is employed by the Company,
     the Executive shall devote, subject to paragraph 1(f), his full time,
     energies and talents to performing his duties under this Agreement.

(c)  The Executive agrees that he shall perform his duties faithfully and
     efficiently subject to the directions of the Board of Directors (the
     "Board") and the Chief Executive Officer (the "CEO") of the Company.  The
     Executive's duties may include providing services for the Company, the
     Holding Company, and the Subsidiaries (as defined below), as determined by
     the CEO; provided that the Executive shall not, without his consent, be
     assigned tasks that would be inconsistent with his position at the Company.
     The Executive will have such authority and power as are inherent to the
     undertakings applicable to his position and necessary to carry out his
     responsibilities and the duties required of him hereunder.

(d)  While the Executive is employed by the Company, he shall be subject to the
     duties that reasonably apply to the Company's officers and employees
     (including, without limitation, the duty of loyalty to the Company).

(e)  The Company may change the Executive's title and duties in the event of
     reorganization, restructuring, or similar circumstances, except that the
     Executive shall have a senior executive position at all times during the
     Agreement Term while he is employed by the Company.
<PAGE>
 
(f)  Notwithstanding the foregoing provisions of this paragraph 1, during the
     Agreement Term, the Executive may devote reasonable time to activities
     other than those required under this Agreement, including the supervision
     of his personal investments, and activities involving professional,
     charitable, educational, religious and similar types of organizations,
     speaking engagements, membership of the boards of directors of other
     organizations, and similar type of activities, to the extent that such
     other activities do not inhibit or prohibit the performance of the
     Executive's duties under this Agreement, or conflict in any material way
     with the business of the Company, the Holding Company, or any Subsidiary;
     provided, however, that except as otherwise expressly provided in this
     Agreement, the Executive shall not serve on the board of any business, or
     hold any position with any business without the consent of the Board and
     the CEO of the Company.

(g)  The Executive will be required to maintain a residence in Bermuda while
     employed by the Company.

(h)  The Company will use its reasonable best efforts to maintain a Bermuda work
     permit for the Executive.  The Executive shall cooperate with the Company
     and the appropriate authorities in maintaining such permit.  The
     Executive's employment by the Company is conditioned upon the Company's
     ability to keep current all required work permits, and except as otherwise
     provided in this paragraph 1(h), the Company shall have no further
     obligation to the Executive if, after employing its reasonable best
     efforts, it is unable to maintain such permits.  If despite the Company's
     best efforts to maintain the Bermuda work permit, the work permit is
     terminated or revoked by the Government of Bermuda through no fault of the
     Executive, then the Executive shall be deemed to have received written
     notice from the Company that his Date of Termination is the date on which
     the termination or revocation of his or her work permit is effective, and
     the Executive shall be entitled to the benefits provided for Termination by
     the Company under Section 3(g). In addition, the Company shall reimburse
     the Executive for reasonable costs actually incurred by the Executive and
     the members of his or her immediate family to relocate to the nation in
     which the Executive maintains citizenship; provided, however, that such
     reimbursement shall be made only if such relocation occurs within a
     reasonable time following such Date of Termination.  The reasonableness of
     the cost and time of relocation shall be determined by the Board of
     Directors of the Company.

(i)  Subject to the provisions of this Agreement, the Executive shall not be
     required to perform services under this Agreement during any period that he
     is Disabled.  The Executive shall be considered "Disabled" during any
     period in which he has a physical or mental disability which renders him
     incapable, after reasonable accommodation, of performing his duties under
     this Agreement.  In the event of a dispute as to whether the Executive is
     Disabled, the Company may refer the same to a licensed practicing physician
     of the Company's choice, and the Executive agrees to submit to such tests
     and examination as such physician shall deem appropriate.

(j)  The "Agreement Term" shall be the period beginning on the Effective Date
     and ending on the second anniversary of the Effective Date; provided,
     however, that beginning on

                                       2
<PAGE>
 
     the first anniversary of the Effective Date, such Agreement Term shall
     automatically be renewed daily, such that at any time on or after the first
     anniversary of the Effective Date, the remaining term shall equal one year.
     However, such additional day-to-day renewals may be terminated by either
     party be delivering written notice of such termination to the other party,
     in accordance with the requirements of paragraph 18.  The cessation of the
     automatic renewals shall be effective on the date such written notice is
     deemed to be given to the other party in accordance with paragraph 18, such
     that the Agreement term shall end on the one-year anniversary of the date
     such written notice is deemed given to the other party.  For purposes of
     this Agreement, a Notice of Termination, as described in paragraph 3(i),
     shall be deemed to be a notice to terminate day-to-day renewals.

(k)  For purposes of this Agreement, the term "Subsidiary" shall mean any
     company (regardless of whether incorporated) during any period in which 50%
     or more of the total combined voting power of all classes of stock (or
     other ownership interest) entitled to vote is owned, directly or
     indirectly, by the Company.

     2.   Compensation.  Subject to the provisions of this Agreement, during the
          ------------                                                          
Agreement Term, while he is employed by the Company, the Company shall
compensate the Executive for the Executive's services as follows:

(a)  Salary.   The Executive shall receive, for each 12-consecutive month period
     ------                                                                     
     beginning on the Effective Date and each anniversary thereof, in
     substantially equal monthly or more frequent installments, an annual base
     salary of $275,000 (the "Salary").  In no event shall the Salary of the
     Executive be reduced to an amount that is less than the amount specified in
     this paragraph (a), or to an amount that is less than the amount that he
     was previously receiving, except to the extent that reductions of the same
     percentage are being made at the same time to the salaries of all other
     Company officers in the corporate office at or above the vice-president
     level, and such Salary shall be restored to its prior level when, and to
     the same extent, as the restoration that applies to the other officers.

(b)  Bonus.  The Executive shall be entitled to receive bonuses from the Company
     -----

     replacement coverage which will provide for replacement of income at a
     commercially reasonable rate during any period in which the Executive is
     Disabled if the disability arose during the Agreement Term and prior to the
     Executive's Date of Termination.  During any period while the Executive is
     Disabled, and is otherwise entitled to receive Salary under this Agreement,
     any Salary payments to the Executive shall be reduced by the amount of any
     benefits paid for the same period of time under the Company's disability
     income replacement coverage.

(d)  Pension.  The Company will provide the Executive with a defined
     -------                                                        
     contribution savings plan, into which the Company will make a contribution
     for each fiscal year equal to 10% of the Salary paid to the Executive for
     such fiscal year.  The plan will also provide that

                                       3

     ----------                                                           
     toward the cost of an automobile in Bermuda, the amount of which will be
     approved by the CEO.  The Company will assume responsibility for the cost
     of insurance, maintenance and similar items.  The Executive's personal use
     of the automobile will be permitted.  This perquisite shall be governed by
     the rules and limitations set down from time to time by the Company.

(f)  Club.  The Company will reimburse the Executive for periodic dues for his
     ----                                                                     
     membership in clubs located in Bermuda in an amount not to exceed $2,400

     Accountant.

     --------------------------------------                                 
     Executive for reasonable expenses, not to exceed $5,000 per fiscal year,
     for tax, accounting, and financial planning services.

(j)  Other Benefits.  Except as otherwise specifically provided to the contrary
     --------------                                                            
     in this Agreement, the Executive shall be provided with the welfare
     benefits and other fringe benefits to the same extent and on the same terms
     as those benefits are provided by the Company from time to time to the
     Company's other senior management employees. However, the Company shall not
     be required to provide a benefit or perquisite under this paragraph 2(j) if
     such benefit or perquisite would duplicate (or otherwise be the same type
     as) a benefit or perquisite specifically required to be provided under
     another provision of this Agreement.

(k)  Expenses.  Upon approval by the CEO, the Company will reimburse the
     --------                                                           
     Executive for reasonable expenses for entertainment, traveling, meals,

     expenses.

     ---------------                                                          
     in commercially reasonable amounts (as reasonably determined by the Board),
     and the Executive shall be covered under such insurance to the same extent
     as other senior management employees of the Company.  The Executive shall
     be eligible for indemnification by the Company under the Company's bye-laws
     as currently in effect. The Company agrees that it shall not take any
     action that would impair the Executive's rights to indemnification under
     the Company's bye-laws, as currently in effect.

                                       4

(m)  Holiday/Vacation.  The Executive shall be subject to the holiday and
     ----------------                                                    
     vacation policy that applies to other senior executives of the Company.

(n)  Dollar Amounts.  As used in this Agreement, "dollars" or numbers preceded
     --------------                                                           
     by the symbol "$" shall mean amounts in United States Dollars.

     3.   Termination.  The Executive's employment during the Agreement Term may
          -----------                                                           
be terminated by the Company or the Executive without any breach of this
Agreement only under the circumstances described in paragraphs 3(a) through
3(g):

(a)  Death.  The Executive's employment will terminate upon his death.
     -----                                                            

(b)  Permanently Disabled.  The Company may terminate the Executive's employment
     --------------------                                                       
     if he is Permanently Disabled.  "Permanently Disabled" means that the
     Executive is eligible for benefits under the Company's long-term disability
     plan.

(c)  Cause.  The Company may terminate the Executive's employment at any time
     -----                                                                   
     for Cause. "Cause" shall mean:

     (i)   the wilful and continued failure by the Executive to substantially
           perform his duties with the Company (other than any such failure
           resulting from the Executive's being Disabled), within a reasonable
           period of time after a written demand for substantial performance is
           delivered to the Executive by the CEO, which demand specifically
           identifies the manner in which the CEO believes that the Executive
           has not substantially performed his duties;

     (ii)  the wilful engaging by the Executive in conduct which is demonstrably
           and materially injurious to the Company or the Holding Company,
           monetarily or otherwise; or

     (iii) the engaging by the Executive in egregious misconduct involving
           serious moral turpitude to the extent that, in the reasonable
           judgment of the CEO, the Executive's credibility and reputation no
           longer conform to the standard of the Company's executives.

     For purposes of this Agreement, no act, or failure to act, on the
     Executive's part shall be deemed "wilful" unless done, or omitted to be
     done, by the Executive not in good faith and without reasonable belief that
     the Executive's action or omission was in the best interest of the Company
     or the Holding Company.

(d)  Constructive Discharge.  If the Executive (i) provides written notice to
     ----------------------                                                  
     the Company of the occurrence of a material breach of this Agreement by the
     Company, which specifically identifies the manner in which the Executive
     believes that the breach has occurred; (ii) the Company fails to correct
     such breach within a reasonable time after such notice; and (iii) the
     Executive resigns within the 60-day period following the

                                       5
<PAGE>
 
     occurrence of such breach, then the Executive shall be considered to have
     been constructively discharged.

(e)  Resignation by Executive.  The Executive may resign for any reason by
     ------------------------                                             
     giving the Company ninety (90) days prior written notice, except the
     Executive will be treated as having resigned under this paragraph 3(e) only
     if he has not been constructively discharged under paragraph 3(d).

(f)  Mutual Agreement. This Agreement may be terminated at any time by the
     ----------------                                                     
     mutual agreement of the parties.  Any termination of the Executive's
     employment by mutual agreement of the parties will be memorialized by an
     agreement which is reduced in writing and signed by the Executive and the
     CEO or other duly appointed officer of the Company.

(g)  Termination by Company.  The Company may terminate the Executive's
     ----------------------                                            
     employment at any time for any reason by giving the Executive prior written
     notice, except the Executive's employment will not be treated as having
     been terminated under this paragraph 3(g) if the termination is for reasons
     of being Permanently Disabled or for Cause.

(h)  Date of Termination.  "Date of Termination" means the last day the
     -------------------                                               
     Executive is employed by the Company, provided that the Executive's
     employment is terminated in accordance with the foregoing provisions of
     this paragraph 3.

(i)  Notice of Termination. Any termination of the Executive's employment by
     ---------------------  
     the Company or the Executive (other than a termination pursuant to
     paragraph 3(a) or paragraph 3(f)) must be communicated by a written Notice
     of Termination to the other party hereto. For purposes of this Agreement, a
     "Notice of Termination" means a dated notice which indicates the specific
     termination provision in this Agreement relied on and which sets forth in
     reasonable detail the facts and circumstances, if any, claimed to provide a
     basis for termination of the Executive's employment under the provision so
     indicated.

     4.   Rights Upon Termination.  This paragraph 4 describes the payments and
          -----------------------                                              
benefits to be provided to the Executive after his Date of Termination:

(a)  Payment of Previously Earned Amounts.  The Executive shall receive payment
     ------------------------------------                                      
     of accrued but unpaid Salary, vacation pay and, if expressly provided for
     in paragraph 4(d), a pro rata portion of his bonus (if any), in each case
     for the period ending with the Executive's Date of Termination.

(b)  No Severance Payments.  If the Executive's Date of Termination occurs
     ---------------------                                                
     during or after the end of the Agreement Term, or because of (i) the
     Executive's death, (ii) his being Permanently Disabled (paragraph 3(b)),
     (iii) his termination for Cause (paragraph 3(c)), or (iv) his resignation
     (paragraph 3(e)), then, except as otherwise expressly provided for

                                       6
<PAGE>
 
     in this Agreement, no payments shall be due to the Executive under this
     Agreement for periods after the Date of Termination.

(c)  Salary Continuation.  If the Executive's Date of Termination occurs during
     -------------------                                                       
     the Agreement Term because of (i) his discharge by the Company for reasons
     other than Cause (described in paragraph 3(c)), or (ii) his constructive
     discharge (described in paragraph 3(d)), the Executive shall continue to
     receive Salary payments (at the rate in effect on the Date of Termination)
     in monthly or more frequent instalments through the earliest of: (i) the
     last day of the Agreement Term; (ii) the date of the Executive's death, or
     (iii) the date, if any, of the breach by the Executive of the non-
     competition requirements of paragraph 7, the confidentiality requirements
     of paragraph 8 or the non-disparagement requirements of paragraph 9.

(d)  Pro rata Bonus.  Except as otherwise provided in this paragraph 4(d), the
     --------------                                                           
     Executive shall not receive a bonus for the fiscal year in which the
     Executive's Date of Termination occurs.  If the Executive's Date of
     Termination occurs during the Agreement Term as a result of (i) the
     Executive's death (ii) his being Permanently Disabled (paragraph 3(b)),
     (iii) his discharge by the Company for reasons other than Cause (described
     in paragraph 3(c)), or (iv) his constructive discharge (described in
     paragraph 3(d)), the Executive shall receive a pro rata portion of the
     bonus which would have been paid pursuant to Exhibit A for the fiscal year
     in which the Executive's Date of Termination occurs.  Such portion, if any,
     shall be calculated for the period ending on the Date of Termination and
     shall be paid to the Executive (or his estate) within a reasonable period
     of time after the Company calculates the bonus amount, if any, for all
     employees for the fiscal year.

(e)  Housing/Living Expenses, Medical Benefits.  If the Executive is entitled to
     -----------------------------------------                                  
     Salary Continuation payments pursuant to paragraph 4(c), the Executive
     shall receive a housing and living expense allowance (described in
     paragraph 2(g)) and may continue to participate in the medical and dental
     plans in which he participated on the day before his Date of Termination
     through the earlier of: (i) the last day for which the Executive receives
     Salary Continuation payments pursuant to paragraph 4(c); or (ii) three (3)
     months after the Executive's Date of Termination.  Participation in the
     medical and dental plans is subject to the Executive's payment of the
     applicable employee portion of the monthly premium cost, if any.  If the
     Company ceases offering the medical and dental plans in which the Executive
     participated on the day before his Date of Termination to Company employees
     during this time, the Executive may elect to participate in any other
     medical or dental plan offered by the Company to its employees, provided
     however, that the Executive shall be responsible for paying the applicable
     employee portion of the monthly premium cost.

(f)  Other Programs.  No benefits shall be payable to the Executive under any
     --------------                                                          
     other severance pay arrangement or similar arrangement maintained by the
     Company or any Subsidiary. Except as otherwise expressly provided in this
     Agreement, no other payments or benefits shall be due to the Executive
     following the Date of Termination (except as otherwise specifically
     provided under the terms of an employee benefit plan or arrangement).

                                       7

     5.   Duties on Termination.  Subject to the provisions of this Agreement,
          ---------------------                                               
during the period beginning on the date of delivery of a Notice of Termination,
and ending on the Date of Termination, the Executive shall continue to perform
his duties as set forth in this Agreement, and shall also perform such services
for the Company and the Holding Company as are necessary and appropriate for a
smooth transition to the Executive's successor, if any. Notwithstanding the
foregoing provisions of this paragraph 5, the Company may suspend the Executive
from performing his duties under this Agreement following the delivery of a
Notice of Termination providing for the Executive's resignation, or delivery by
the Company of a Notice of Termination providing for the Executive's termination
of employment for any reason; provided, however, that during the period of
suspension (which shall end on the Date of Termination), the Executive shall
continue to be treated as employed by the Company for other purposes, and his
rights to compensation or benefits shall not be reduced by reason of the
suspension.

     6.   Set-Off.  If the Executive's employment with the Company is terminated
          -------                                                               
for any reason and, under the terms of this Agreement, the Executive is
otherwise entitled to receive Salary and bonus payments, such payments will be
reduced by the amount of any salary and bonus payments the Executive receives in
connection with other employment.

     7.   Non-competition.  While the Executive is employed by the Company, and
          ---------------                                                      
during the Non-Competition Period (as defined below), the Executive agrees that
he will not directly or indirectly perform services in a financial-related
position in Bermuda for a direct competitor of the Company.  A financial-related
position shall include, but is not limited to, a financial officer or
comptroller.

For purposes of this paragraph 7:

     "Non-Competition Period" shall be determined as follows:

     (1)  If the Executive's Date of Termination occurs under circumstances
          other than those described in paragraph 3(d) (relating to constructive
          discharge) or paragraph 3(g) (relating to certain terminations by the
          Company), the Non-Competition Period shall be the period beginning on
          the Date of Termination, and ending on the twenty-four-month (24)
          anniversary of the Date of Termination.

     (2)  If the Executive's Date of Termination occurs under circumstances
          described in paragraph 3(d) (relating to constructive discharge) or
          paragraph 3(g) (relating to certain terminations by the Company), the
          Non-Competition Period shall be the period beginning on the Date of
          Termination, and ending on the earlier to occur of the last day of the
          Agreement Term or the twenty-four-month (24) anniversary of the Date
          of Termination.  However, under this paragraph (B), the Company, in
          its discretion, by notice provided to the Executive not later than
          fifteen (15) days after the Date of Termination, may extend the Non-
          Competition Period beyond the end of the Agreement Term, to a date
          specified in such notice (but not later than the twenty-four-month
          anniversary of the Date of Termination), but only if

                                       8
<PAGE>
 
          the Company agrees to provide the salary continuation payments
          described in paragraph 4(c) during such Non-Competition Period.

     Nothing in this paragraph 7, paragraph 8 or paragraph 9 shall be construed
as limiting the Executive's duty of loyalty to the Company while he is employed
by the Company or any other duty he may otherwise have to the Company while he
is employed by the Company.

     8.   Confidential Information.  Except as may be required by the lawful 
          ------------------------     
order of a court or agency of competent jurisdiction, or except to the extent
that the Executive has express authorization from the Company, the Executive
agrees to keep secret and confidential indefinitely all non-public information
(including, without limitation, information regarding litigation and pending
litigation) concerning the Company, the Holding Company, and the Subsidiaries
which was acquired by or disclosed to the Executive during the course of his
employment with the Company, or during the course of his consultation with the
Company following his termination of employment (regardless of whether
consultation is pursuant to paragraph 10), and not to disclose the same, either
directly or indirectly, to any other person, firm, or business entity, or to use
it in any way. To the extent that the Executive obtains information on behalf of
the Company, the Holding Company, or any of the Subsidiaries that may be subject
to attorney-client privilege as to the Company's attorneys, the Executive shall
take reasonable steps to maintain the confidentiality of such information and to
preserve such privilege. Nothing in the foregoing provisions of this paragraph 8
shall be construed so as to prevent the Executive from using, in connection with
his employment for himself or an employer other than the Company, the Holding
Company, or any of the Subsidiaries, knowledge which was acquired by him during
the course of his employment with the Company, the Holding Company, and the
Subsidiaries, and which is generally known to persons of his experience in other
companies in the same industry.

     9.   Non-Disparagement.  The Executive agrees that, while he is employed by
          -----------------                                                     
the Company, and after his Date of Termination, he shall not make any false,
defamatory or disparaging statements about the Company, the Holding Company, the
Subsidiaries, or the officers or directors of the Company, the Holding Company,
or the Subsidiaries that are reasonably likely to cause material damage to the
Company, the Holding Company, the Subsidiaries, or their officers or directors.
While the Executive is employed by the Company, and after his Date of
Termination, the Company agrees, on behalf of itself, the Holding Company, and
the Subsidiaries, that neither the officers nor the directors of the Company,
the Holding Company, or the Subsidiaries shall make any false, defamatory or
disparaging statements about the Executive that are reasonably likely to cause
material damage to Executive.

     10.  Defense of Claims.  The Executive agrees that, for the period 
          -----------------
beginning the Effective Date, and continuing for a reasonable period after the
Executive's termination of employment with the Company, the Executive will
cooperate with the Company, the Holding Company and the Subsidiaries in defense
of any claims that may be made against the Company, the Holding Company and the
Subsidiaries, and will cooperate with the Company, the Holding Company or the
Subsidiaries in the prosecution of any claims that may be made by the Company,
the Holding Company or the Subsidiaries, to the extent that such claims may
relate to services performed by the Executive for the Company. The Executive
agrees to promptly inform

                                       9
<PAGE>
 
the Company if he becomes aware of any lawsuits involving such claims that may
be filed against the Company, the Holding Company or the Subsidiaries.  The
Company agrees to reimburse the Executive for all of the Executive's reasonable
out-of-pocket expenses associated with such cooperation, including travel
expenses.  For periods after the Executive's employment with the Company
terminates, the Company agrees to provide reasonable compensation to the
Executive for such cooperation.  The determination of the reasonableness of such
compensation shall take into account information provided to the Company by the
Executive or otherwise known to the Company, which may include, without
limitation, (a) the Executive's rate of compensation at the time he ceased
employment with the Company, and whether he is then receiving other compensation
payments from the Company; (b) the Executive's rate of compensation at the time
of such cooperation; (c) the amount of time required of the Executive for such
cooperation; (d) difficulty of the issues as to which the cooperation is
required; (e) the amount of inconvenience to the Executive resulting from such
cooperation (including consideration of factors such as the amount of travel
required of the Executive, the effect on other commitments of the Executive, and
the amount of advance notice provided to the Executive); and (f) whether such
cooperation would be legally required in the absence of the requirements of this
paragraph 10.  The Executive also agrees to promptly inform the Company if he is
asked to assist in any investigation of the Company, the Holding Company or the
Subsidiaries (or their actions) that may relate to services performed by the
Executive for the Company, regardless of whether a lawsuit has then been filed
against the Company, the Holding Company or the Subsidiaries with respect to
such investigation.

     11.  Remedies.  The Executive acknowledges that the Company or the Holding
          --------                                                             
Company would be irreparably injured by a violation of paragraph 7, paragraph 8,
or paragraph 9, and he agrees that the Company, in addition to any other
remedies available to it for such breach or threatened breach, shall be entitled
to a preliminary injunction, temporary restraining order, or other equivalent
relief, restraining the Executive from any actual or threatened breach of either
paragraph 7, paragraph 8 or paragraph 9.  The Company acknowledges that the
Executive would be irreparably injured by a violation of paragraph 9, and the
Company agrees that the Executive, in addition to any other remedies available
to him for such breach or threatened breach, shall be entitled to a preliminary
injunction, temporary restraining order, or other equivalent relief, restraining
the Company from any actual or threatened breach of paragraph 9.  If a bond is
required to be posted in order for the Company or the Executive to secure an
injunction or other equitable remedy, the parties agree that said bond need not
be more than a nominal sum.

     12.  Nonalienation.  The interests of the Executive under this Agreement 
          -------------
are not subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, attachment, or garnishment by creditors of the
Executive or the Executive's beneficiary.

     13.  Amendment.  This Agreement may be amended or canceled only by mutual
          ---------                                                           
agreement of the parties in writing without the consent of any other person.  So
long as the Executive lives, no person, other than the parties hereto, shall
have any rights under or interest in this Agreement or the subject matter
hereof.

                                   ---------


                               BONUS COMPUTATION
                               -----------------

     A-1.  Purpose.  This Exhibit A is attached to and forms a part of the
           -------                                                        
employment agreement (the "Agreement") between Andrew Cook (the "Executive") and
LaSalle Re Limited (the "Company").  The purpose of this Exhibit A is to set
forth the terms of the bonus program described in paragraph 2(b) of the
Agreement.

     A-2.  Guidelines.  The bonus shall be determined in accordance with the
           ----------                                                       
following guidelines:

 .    A discretionary bonus may be awarded annually by the Board of the Company
     after considering the recommendation of the CEO of the Company.

 .    A non-discretionary bonus shall be earned and paid annually based upon the
     Company's Return on Equity (defined below) achieved for each fiscal year of
     the Company, while the Executive is employed by the Company.

 .    The non-discretionary annual bonus calculation will be based on the
     Company's Return on Equity earned each year. If the Company's Return on
     Equity for any year exceeds 15%, the bonus will be paid according to the
     following formula:

     .    For each 1% improvement in Return on Equity above 15%, an amount
          equal to 10.0 % of The Executive's Salary will be paid.

     .    For each 1% improvement in Return on Equity above 22.5%, an amount
          equal to 15.0 % of The Executive's Salary will be paid.

     .    For Return on Equity results between whole percentages (but above
          15%), the percentage of Salary awarded will be increased by
          interpolation.

     .    The "Return on Equity" for any fiscal year shall be equal to the net
          income of the Company for the fiscal year, divided by shareholders'
          equity at the beginning of the period (as determined on the basis of
          U.S. generally accepted accounting principles).  For purposes of this
          calculation any unrealized appreciation or depreciation of the
          Company's investments shall be disregarded (both as to the numerator
          and the denominator).  Payments made to CNA Financial Corporation or
          its affiliates under the Underwriting Support Services Agreement will
          not reduce net income in determining Return on Equity.

     2.   By substituting the following for subsection 2.1:

               "2.1.   Eligibility.  Plan participation shall be available to
                       -----------                                           
     (and shall be limited to): (a) any person who is an Eligible Associate and
     who has completed one continuous year as an Eligible Associate, and (b) any
     person who is a Director.  Notwithstanding the foregoing provisions of this
     subsection 2.1, an individual described in clause (a) immediately above may
     participate in the Plan for any calendar year only if he is an Eligible
     Associate on the first day of that year; provided, however, that for the
     Subscription Periods (as defined below) beginning on July 1, 1996 and
     October 1, 1996, an individual may participate in the Plan for such
     Subscription Period if he is an Eligible Associate on the first day of that

     continuously through the last day of such Subscription Period."

     3.   By adding the following new paragraph (c) to subsection 2.2 as a part
          thereof:

          "(c) A Director may elect to purchase Stock during a Subscription

               Subscription Period by filing with the Committee, at such time

               Period, a written election specifying the dollar amount to be
               used to purchase Stock, subject to the limitations of subsection
               2.4, accompanied by a cash payment equal to such amount."

     4.   By substituting the following for subsection 2.4:

               "2.4  Purchase of Stock.  With respect to each Subscription
                     -----------------

               of the Stock.

          (b)  A Participant shall be deemed to have purchased the shares of
               Stock on the third business day following the applicable Price
               Date (the 'Purchase Date').

          (c)  Any accumulated payroll deductions of a Participant or payments
               made by a Director that are not used to purchase full shares of
               Stock under the Plan shall be held and applied toward the
               purchase of Stock in the next following Subscription Period.
               Notwithstanding the foregoing, the Participant may request that
               such amount be paid to the Participant by filing a written
               application with the Committee in such form and at such time as
               the Committee may require, in which case such amount shall be
               paid to the Participant without interest as soon as practicable
               following the Committee's receipt of the request.

          (d)  No Participant shall have the right to purchase more than $25,000
               in value of Stock under the Plan (and any other employee stock
               purchase plan maintained by the Company or any Related Company)

          (e)  No Participant shall have the right to purchase more than an
               amount equal to 25% of the Participant's bonus payment in value

          Eligible Associate may discontinue his participation in the Plan for
          any Subscription Period, by notifying the Committee of such
          discontinuance in writing, in such form and at such time as the

          Subscription Period for any reason, all payroll deductions accumulated

               payroll deductions with respect to such Participant will be made
               for that Subscription Period, no further payment toward the

               the Plan shall confer upon the holder thereof any right as a
               shareholder of the Company prior to the date on which the shares
               of Stock are purchased pursuant to the terms of the Plan."

               as a Director; provided, that a Date of Termination shall not be

               between two entities as an Eligible Associate; further provided
               that a Date of Termination shall not be deemed to occur by reason
               of a Participant's cessation of service as a Director if
               immediately following such cessation of service he becomes or
               continues to be an Eligible Associate nor by reason of a
               Participant's cessation as an Eligible Associate if immediately

INSOLVENCY OF THE REASSURED
- ---------------------------

Amounts due to the Reassured under this Agreement shall be payable by the 
Reinsurers on the basis of the liability of the Reassured under the cessions 
hereto without diminution because of the insolvency of the Reassured.

In the event of the insolvency of the Reassured, the Liquidator or Receiver or 
Statutory Successor of the Reassured shall give written notice to the Reinsurers
of the pendency of any claim against the insolvent Reassured on the cessions 
hereto within a reasonable time after such claim is filed in the insolvency 
proceedings. During the pendency of such claim the Reinsurers may investigate 
such claim and intervene, at their own expense, in the proceedings where such a 
claim is to be adjudicated and interpose any defence or defences which they may 
deem available to the Reassured or its Liquidator or Receiver or Statutory 
Successor. The expense thus incurred by the Reinsurers shall be chargeable, 
subject to court approval, against the insolvent Reassured as part of the 
expense of liquidation to the extent of a proportionate share of the benefit 
which may accrue to the Reassured solely as a result of the defence so 
undertaken by the Reinsurers.

When two or more Reinsurers are involved in the same claim and a majority in
interest elect to investigate the claim and/or interpose defence to such claim,
the expense shall be apportioned in accordance with the terms of the above
paragraph as though such expense had been incurred by the Reassured.

Should the Reassured go into liquidation or should a receiver be appointed, the 
Reinsurers shall be entitled to deduct from any sums which may be or may become 
due to the Reassured under this Agreement any sums which are due to the 
Reinsurers from the Reassured under this Agreement and which are payable at a 
fixed or stated date, as well as any other sums due to the Reinsurers which are 
permitted to be offset under applicable law.

In the event of the insolvency of the Reassured, the amounts due to the 
Reassured under this Agreement shall be payable by the Reinsurers directly to 
the Reassured or to its Liquidator, Receiver or Statutory Successor.

DELAYS, ERRORS OR OMISSIONS
- ---------------------------

No inadvertent delay, error or omission shall be held to relieve either party 
hereto of any liability which would have attached to them under this Agreement 
if such delay, error or omission had not been made, provided that rectification
is made immediately upon discovery.

                                  ARTICLE 17

OFFSET

Each party hereto shall have and may exercise in the event of the insolvency of
the other or the non-payment by the other of obligations where due hereunder,
the right to offset any balance or balances whether on account or premiums,
commissions, claims or losses, adjustment expenses, salvage or any other amount
due from that party to the other party hereto under this Agreement against the
balance or balances due or to become due to the offsetting party from the other
party under this Agreement.

     receiving a written request from the other for arbitration, the claimant

     written notice thereof to the respondent. Within 30 days of receiving such
     notice the respondent shall appoint his arbitrator and give written notice
     thereof to the claimant, failing which the claimant may apply to the
     appointor hereafter named to nominate an arbitrator on behalf of the
     respondent.

3.   Before they enter upon a reference the two arbitrators shall appoint a
     third arbitrator. Should they fail to appoint such a third arbitrator
     within 30 days of the appointment of the respondent's arbitrator then
     either of them or either of the parties may apply to the appointor for the
     appointment of the third arbitrator. The three arbitrators shall decide by
     majority. If no majority can be reached the verdict of the third arbitrator
     shall prevail. He shall also act as chairman of the tribunal.

4.   Unless the parties otherwise agree the arbitration tribunal shall consist
     of persons (including those who have retired) with not less than ten years
     experience of insurance or reinsurance as persons engaged in the industry
     itself or as lawyers or other professional advisers.

5.   The arbitration tribunal shall, so far as is permissible under the law and
     practice of the place of arbitration, have power to fix all procedural
     rules for the holding of the arbitration including discretionary power to
     make orders as to any matters which it may consider proper in the
     circumstances of the case with regard to pleadings, discovery, inspection
     of the documents, examination of witnesses and any other matter whatsoever
     relating to the conduct of the arbitration and may receive and act upon
     such evidence whether oral or written strictly admissible or not as it
     shall in its discretion think fit.

6.   The appointor shall be the Chairman for the time being of ARIAS (UK) or if
     he is unavailable or it is inappropriate for him to act for any reason,
     such person as may be nominated by the Committee of ARIAS (UK). If for any
     reason such persons decline or are unable to act, then the appointor shall
     be the Judge of the appropriate Courts having jurisdiction at the place of
     arbitration.

7.   All costs of the arbitration shall be determined by the arbitration
     tribunal who may, taking into account the law and practice of the place of
     arbitration, direct to and by whom and in what manner they shall be paid.

8.   The place of arbitration may be chosen by the parties, but in default of
     such choice, the place of arbitration shall be London, England.

9.   The proper law of this Agreement shall be the law of England.

10.  The award of the arbitration tribunal shall be in writing and binding upon
     the parties who consent to carry out the same.

In the event of the insolvency of the Reassured, the Liquidator or Receiver or 
Statutory Successor of the Reassured shall give written notice to the Reinsurers
of the pendency of any claim against the insolvent Reassured on the cessions 
hereto within a reasonable time after such claim is filed in the insolvency 
proceedings.  During the pendency of such claim the Reinsurers may investigate 
such claim and intervene, at their own expense, in the proceedings where such a 
claim is to be adjudicated and interpose any defence or defences which they may 
deem available to the Reassured or its Liquidator or Receiver or Statutory 
Successor.  The expense thus incurred by the Reinsurers shall be chargeable, 
subject to court approval, against the insolvent Reassured as part of the 
expense of liquidation to the extent of a proportionate share of the benefit 
which may accrue to the Reassured solely as a result of the defence so 
undertaken by the Reinsurers.

When two or more Reinsurers are involved in the same claim and a majority in 
interest elect to investigate the claim and/or interpose defence to such claim, 
the expense shall be apportioned in accordance with the terms of the above 
paragraph as though such expense had been incurred by the Reassured.

Should the Reassured go into liquidation or should a receiver be appointed, the 
Reinsurers shall be entitled to deduct from any sums which may be or may become 
due to the Reassured under this Agreement any sums which are due to the 
Reinsurers from the Reassured under this Agreement and which are payable at a 
fixed or stated date, as well as any other sums due to the Reinsurers which are 
permitted to be offset under applicable law.

In the event of the insolvency of the Reassured, the amounts due to the 
Reassured under this Agreement shall be payable by the Reinsurers directly to 
the Reassured or to its Liquidator, Receiver or Statutory Successor.

hereto of any liability which would have attached to them under this Agreement

is made immediately upon discovery.

the right to offset any balance or balances whether on account or premiums,

ARBITRATION

1.   All matters in difference between the parties arising under, out of or in
     connection with this Agreement, including formation and validity, and
     whether arising during or after the period of this Agreement, shall be
     referred to an arbitration tribunal in the manner hereinafter set out.

2.   Unless the parties appoint a sole arbitrator within 14 days of one
     receiving a written request from the other for arbitration, the claimant
     (the party requesting arbitration) shall appoint his arbitrator and give
     written notice thereof to the respondent. Within 30 days of receiving such
     notice the respondent shall appoint his arbitrator and give written notice
     thereof to the claimant, failing which the claimant may apply to the
     appointor hereafter named to nominate an arbitrator on behalf of the
     respondent.

3.   Before they enter upon a reference the two arbitrators shall appoint a
     third arbitrator. Should they fail to appoint such a third arbitrator
     within 30 days of the appointment of the respondent's arbitrator then
     either of them or either of the parties may apply to the appointor for the
     appointment of the third arbitrator. The three arbitrators shall decide by
     majority. If no majority can be reached the verdict of the third arbitrator
     shall prevail. He shall also act as chairman of the tribunal.

4.   Unless the parties otherwise agree the arbitration tribunal shall consist
     of persons (including those who have retired) with not less than ten years'
     experience of insurance or reinsurance as persons engaged in the industry
     itself or as lawyers or other professional advisers.

5.   The arbitration tribunal shall, so far as is permissible under the law and
     practice of the place of arbitration, have power to fix all procedural
     rules for the holding of the arbitration including discretionary power to
     make orders as to any matters which it may consider proper in the
     circumstances of the case with regard to pleadings,

     discovery, inspection of the documents, examination of witnesses and any
     other matter whatsoever relating to the conduct of the arbitration and may
     receive and act upon such evidence whether oral or written strictly
     admissible or not as it shall in its discretion think fit.

6.   The appointer shall be the Chairman for the time being of ARIAS (UK) or if
     he is unavailable or it is inappropriate for him to act for any reason,
     such person as may be nominated by the Committee of ARIAS (UK). If for any
     reason such persons decline or are unable to act, then the appointor shall
     be the Judge of the appropriate Courts having jurisdiction at the place of
     arbitration.

7.   All costs of the arbitration shall be determined by the arbitration
     tribunal who may, taking into account the law and practice of the place of
     arbitration, direct to and by whom and in what manner they shall be paid.

8.   The place of arbitration may be chosen by the parties, but in default of 
     such choice, the place of arbitration shall be Amsterdam.

9.   The proper law of this Agreement shall be the law of the Netherlands.

10.  The award of the arbitration tribunal shall be in writing and binding upon
     the parties who consent to carry out the same.

Within 30 days after the close of each quarter, the Retrocedent shall furnish 
the Retrocessionaires with a report summarizing the gross premium, commission

          date of the billing/proof of loss.

     B.   Payment of any premium shall be due to the Retrocessionaires within 90
          calendar days of the date specified in this Agreement. Any premium
          adjustments shall be due by the debtor party within 150 calendar days
          of the expiry of this Agreement.

     C.   Payment on return of premiums, commissions, profit sharing, or any
          amounts not provided in paragraphs A. or B. above, shall have the due 
          date as specified in this Agreement. If no due date is specified, 
          the due date shall be 90 days following the date of billing.

     D.   Failure by the Retrocessionaire or the Retrocedent to comply with
          their respective payment obligations within the time periods as herein
          provided will result in a compound interest penalty payable at a rate
          equal to the 90-day Treasury Bill rate as published in the Money Rate
          Section or any successor section of The Wall Street Journal on the
                                              -----------------------         
          first business day following the date a remittance becomes due, plus
          1% per annum, to be compounded and adjusted quarterly.  Any interest
          which occurs pursuant to this Article shall be calculated by the party
          to which it is owed.  The accumulation of the number of days that any
          payment is past due will stop on the date that the Intermediary, where
          applicable, receives payment.

     E.   The validity of any claim or payment may be contested under the
          provisions of this Agreement. If the debtor party prevails in an
          arbitration or any other proceeding, there shall be no interest
          penalty due. Otherwise, any interest will be calculated and due as
          outlined above.

     F.   If a Retrocessionaire advances payment of any claim it is contesting,
          and prevails in the contest, the Retrocedent shall return such payment
          plus pay interest on same, calculated as per the provisions of this 
          Article.

     G.   Any interest that occurs pursuant to this Article may be waived by the
          party to which it is owed. Further, any interest which is calculated
          pursuant to this Article that is $100 or less shall be waived. Waiver
          of such interest, however, shall not affect the waiving party's rights
          to similar interest for any other failure by the other party to make
          payment when due under this Article.

     H.   Nothing in this Article shall diminish any legal remedies that either
          party may have against the other.

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

     THIS AGREEMENT is made and entered into by and between CONTINENTAL
CASUALTY COMPANY, an Illinois corporation, (hereinafter called the
"Retrocedent") of the one part, and the various Retrocessionaires as identified
by the attached Interests and Liabilities Agreements (hereinafter called the
"Retrocessionaires") of the other part.

     WITNESSETH:

     That in consideration of the mutual covenants hereinafter contained and 
upon the terms and conditions hereinbelow set forth, the parties hereto agree as
follows:

                                   ARTICLE I
                                   ---------

COVERAGE
- --------

     The Retrocedent shall cede to the Retrocessionaires, and the
Retrocessionaires shall accept, a 33.33% of $5, 000,000 (i.e, $1,666,500) quota
share participation in respect to all original contracts written or renewed by
the Retrocedent with an effective date during the term of this Agreement and
classified by the Retrocedent as "London Market Catastrophe Excess of Loss
Reinsurance," where 100% of the layer is written by the Retrocedent and coded
Product Type 6308.

     The limit of liability to the Retrocessionaires shall not exceed 33.33% of 
$5,000,000 (i.e., $1,666,500) any one occurrence, any one original reinsured, 
subject to an aggregate limitation of no more than 33.33% of $20,000,000 (i.e., 
$6,666,000) any one occurrence. Should any loss involve this reinsurance, the 
obligation of the Retrocessionaires shall be automatically reinstated as to any 
subsequent loss for the full

     amount of reinsurance as set forth above. The Retrocedent shall retain
     a minimum of 66.67% of $5,000,000 (i.e., $3,333,500) of all cessions 
     to this Agreement net.

          All reinsurance for which the Retrocessionaires shall be obligated by
     virtue of this Agreement shall be subject to the same terms, rates,
     conditions, interpretations, waivers, modifications, and alterations as the
     respective original contracts of the Retrocedent to which this reinsurance 
     applies. Nothing herein shall in any manner create any obligations or 
     establish any rights against the Retrocessionaires in favor of any third 
     parties or any persons not parties to this Agreement except as provided in 
     the Insolvency Article. The Retrocedent shall be the sole judge of what 
     constitutes any one occurrence, any one original reinsured.

                                  ARTICLE II
                                  ----------

     TERM
     ----

          This Agreement shall apply to all losses occurring on original 
     contracts written or renewed with an effective date during the 12-month 
     period commencing January 1, 1998, 12:01 a.m. Standard Time. The 
     Retrocessionaires shall remain liable for all losses under original 
     contracts in force until their expiration or renewal dates, whichever come 
     first, plus an additional 12 month period should an original contract be 
     renewed at an original reinsured's option. In addition, the 
     Retrocessionaires shall remain liable as respects any run-off obligations 
     under the original contracts covered hereunder.

          In the event a Retrocessionaire opts not to continue its participation
     on the agreement replacing this Agreement, the Retrocessionaire shall remit
     to the Retrocedent 90% of the Retrocessionaire's share of the positive 
     balance of premium received, less

     losses paid, and less ceding and other commissions within 30 days after the
     termination of the Agreement. This provision shall not apply in the event 
     this Agreement is not renewed.

          Notwithstanding the cancellation of this Agreement as hereinabove
     provided, its provisions shall continue to apply to all unfinished business
     hereunder to the end that all obligations and liabilities incurred by each
     party hereunder prior to such termination shall be fully performed and
     discharged.

loss expense (unless defined as part of loss in reinsured original contracts)
and shall benefit pro rata in all salvages, subrogations, discounts, and other
recoveries.

                                  -----------

EXTRA CONTRACTUAL OBLIGATIONS

     This Agreement shall protect the Retrocedent, within the limits hereof,

furnish the Retrocessionaires with a report summarizing the gross premium, 
commission allowed on the gross premium, premium ceded less return premium and 
commission, losses paid, loss expenses paid, salvage recovered, and net balance 
due either party. The quarterly report also shall contain a statement showing

losses and loss expense incurred during the quarter. All amendments or
adjustments, including reinstatement premium, shall be accounted for on a year-
of-account basis. Amounts due the Retrocessionaires shall be remitted with said
report. Amounts due the Retrocedent shall be remitted within 30 days following 
receipt of the report.

     Within 60 days following the expiration of this Agreement, the Retrocedent 
shall furnish the Retrocessionaires with a report detailing the unearned 
premium, calculated on a monthly pro rata basis, as well as the December 31st

shall also furnish the Retrocessionaires with any additional information they
may require to prepare their financial statements.

     Should payment due from the Retrocessionaires exceed their share of 
$250,000, the Retrocedent may give the Retrocessionaires notice of payment made 
or its intention to make payment on a certain date. If the Retrocedent has paid 
the loss, payment shall be made by the Retrocessionaires immediately. If the 
Retrocedent intends to pay the loss by a certain date and has submitted a proof 
of loss or similar document, payment shall be due from the Retrocessionaires 24 
hours prior to that date, provided the Retrocessionaires have a period of five 
working days after receipt of said notice to dispatch the payment. Cash loss 
amounts specifically remitted by the Retrocessionaires as set forth herein shall
be credited to their next quarterly account.


                                  ARTICLE IX
                                  ----------

RESERVES AND FUNDING
- --------------------

     (This Article is only applicable to those Retrocessionaires who cannot 
     qualify for credit by each governmental authority having jurisdiction over 
     the Retrocedent's reserves.)

     As regards original contracts issued by the Retrocedent coming within the 
scope of this Agreement, the Retrocedent agrees that, when it files with the 
Insurance Department or sets up on its books reserves for known losses that have
been reported to the Retrocessionaires (including loss and loss expense paid by 
the Retrocedent and loss and loss expense reported and outstanding) and/or 
reserves for unearned premium, which it is required by law to set up, it shall 
forward to the Retrocessionaires a statement showing the proportion of such loss
reserves applicable to them. The Retrocessionaires hereby

AR 1846-A98 -- 11/1/98
(12/11/97)
                                       7
<PAGE>
 
agree that they shall fund such reserves by claims advances, Letters of Credit, 
or a combination thereof.  The Retrocessionaires shall have the option of 
determining the method of funding, provided it is acceptable to the Retrocedent 
and the applicable regulatory authorities.

     If the Retrocessionaires' choice of funding is or includes a Letter of 
Credit, the Retrocessionaires hereby agree that they shall apply for and secure 
delivery to the retrocedent of a clean, irrevocable, and unconditional Letter of
Credit, dated on or before December 31 of the year in which the request is made,
and issued by Citibank, N.A., and containing provisions acceptable to the 
insurance regulatory authorities having jurisdiction over the Retrocedent's 
reserves, in an amount equal to the Retrocessionaire's proportion of such 
reserves applicable to them as shown in the statement prepared by the 
Retrocedent.  Under no circumstances shall any amount relating to reserves in 
respect of Incurred But Not Reported losses be included in the amount of the 
Letter of Credit.

     The Letter of Credit shall be issued for a period of not less than one 
year, and shall be automatically extended for one year from its date of 
expiration or any future expiration date unless 30 days prior to any expiration 
date Citibank N.A. notifies the Retrocedent by registered mail that it elects 
not to consider the Letter of Credit extended for any additional period.

     Notwithstanding any other provisions of this Agreement, the Retrocedent or
its court-appointed successor in interest may draw upon the claims advances
and/or Letters of Credit at any time without diminution because of the
insolvency of the Retrocedent or of any Retrocessionaire for one or more of the
following purposes only:

     A.   To reimburse the Retrocedent for the Retrocessionaire's share of 
          unearned premium on original contracts reinsured hereunder or account 
          of cancellations of such original contracts.

     B.   To pay the Retrocessionaires share or to reimburse the Retrocedent for
          the Retrocessionaire's share of any loss reinsured by this Agreement,
          which has not been otherwise paid.

     C.   To make refund of any sum in excess of the actual amount required to
          pay the Retrocessionaire's share of any liability reinsured by this
          Agreement.

     D.   In the event of non-extension of the Letter of Credit as provided for
          above, to establish deposit of the Retrocessionaire's share for
          unearned premium and/or losses, including reserves for incurred but
          not reported losses under this Agreement. Such cash deposit shall be
          held in an interest bearing account separate from the Retrocedent's
          other assets, and interest thereon shall accrue to the benefit of the
          Retrocessionaires.

     Citibank, N.A. shall have no responsibility whatsoever in connection with
the propriety of withdrawals made by the Retrocedent or the disposition of funds
withdrawn, except to ensure that withdrawals are made only upon the order of
properly authorized representatives of the Retrocedent.

     At annual intervals, or more frequently as agreed but never more frequently
than semi-annually, the Retrocedent shall prepare and forward to the 
Retrocessionaires a statement to reflect the Retrocessionaires' share of 
reserves for losses and/or unearned premium. If the statement shows that the 
Restrocessionaires' share of such reserves exceeds the balance available through
claims advances and/or Letters of Credit as of the statement date, the 
Retrocessionaires shall, within 30 days after receipt of notice of such excess,
make an adjustment to increase the amount available. If, however, the statement
shows that the Retrocessionaires' share of such reserves is less than the
balance available through the chosen method of funding as of the statement date,
the Retrocedent shall,

within 30 days after receipt of written request from the Retrocessionaires, 
release such excess credit by making the appropriate adjustment.

          date as specified in this Agreement. If no due date is specified, the
          due date shall be 90 days following the date of billing.

     D.   Failure by a Retrocessionaire or the Retrocedent to comply with their
          respective payment obligations within the time periods as herein
          provided will result in a compound interest penalty payable at a rate
          equal to the 90-day Treasury Bill rate as published in the Money Rate
          Section or any successor section of The Wall Street Journal on the

          1% per annum, to be compounded and adjusted quarterly. Any interest
          which occurs pursuant to this Article shall be calculated by the party
          to which it is owed. The accumulation of the number of days that any
          payment is past due will stop on the date that the Intermediary, where
          applicable, receives payment.

     E.   The validity of any claim or payment may be contested under the
          provisions of this Agreement. If the debtor party prevails in an
          arbitration or any other proceeding, there shall be no interest
          penalty due. Otherwise, any interest will be calculated and due as
          outlined above.

     F.   If a Retrocessionaire advances payment of any claim it is contesting,
          and prevails in the contest, the Retrocedent shall return such payment
          plus pay interest on same, calculated as per the provisions of this
          Article.

          party to which it is owed. Further, any interest which is calculated
          pursuant to this Article that is $100 or less shall be waived. Waiver
          of such interest, however, shall not affect the waiving party's rights
          to similar interest for any other failure by the other party to make
          payment when due under this Article.

upon discovery.

INSOLVENCY

     In the event of the Retrocedent's insolvency, the reinsurance afforded by 
this Agreement shall be payable by the Retrocessionaires on the basis of the 
Retrocedent's liability under the original contracts reinsured without 
diminution because of the Retrocedent's insolvency or because its liquidator, 
receiver, conservator, or statutory

successor has failed to pay all or a portion of any claims, subject however to
the right of the Retrocessionaires to offset against such funds due hereunder,
any sums that may be payable to them by said insolvent Retrocedent in accordance
with the Offset Article. The reinsurance shall be payable by the
Retrocessionaires directly to the Retrocedent, its liquidator, receiver,
conservator, or statutory successor except (a) where this Agreement specifically
provides another payee of such reinsurance in the event of the Retrocedent's
insolvency or (b) where the Retrocessionaires, with the consent of the direct
insured or insureds, have assumed such policy obligations of the Retrocedent as
direct obligations of themselves to the payees under such policies in
substitution for the Retrocedent's obligation to such payees.

     The Retrocedent's liquidator, receiver, conservator, or statutory successor
shall give written notice of the pendency of a claim against the Retrocedent
under the original contracts within a reasonable time after such claim is filed
in the insolvency proceeding. During the pendency of such claim, the
Retrocessionaires may investigate said claim and interpose in the proceeding
where the claim is to be adjudicated, at their own expense, any defense that
they may deem available to the Retrocedent, its liquidator, receiver,
conservator, or statutory successor. The expense thus incurred by the
Retrocessionaires shall be chargeable against the Retrocedent, subject to court
approval, as part of the expense of conservation or liquidation to the extent
that such proportionate share of the benefit shall accrue to the Retrocedent
solely as a result of the defense undertaken by the Retrocessionaires. Where two
or more Retrocessionaires are involved in the same claim, and a majority in
interest elect to interpose defense to such claim, the expense shall be

expense had been incurred by the Retrocedent.

under this Agreement shall have all rights, as more fully set forth in Section 
173 of Illinois Insurance Code, as amended.

ARBITRATION
- -----------

          In the event of any arbitration between the Retrocedent and its 
reinsureds under the terms of any original contract, the Retrocessionaires agree
unreservedly to abide by the result of such arbitration.

          As a condition precedent to any right of action hereunder, any dispute
arising out of this Agreement, whether arising before or after termination,
shall be submitted to the decision of a board of arbitration composed of two
arbitrators and an umpire, meeting in Chicago, Illinois unless otherwise agreed.

          The members of the board of arbitration shall be active or retired, 
disinterested officials of insurance or reinsurance companies or Underwriters at
Lloyd's, London. Each party shall appoint its arbitrator, and the two 
arbitrators shall choose an umpire before instituting the hearing. If the 
respondent fails to appoint its arbitrator within four weeks after being 
requested to do so by the claimant, the claimant shall also appoint the second 
arbitrator. If the two arbitrators fail to agree upon the appointment of an 
umpire within four weeks after their nominations, they shall request the
American Arbitration Association to appoint an umpire. Both parties shall be
promptly notified, in writing, of the appointment of the umpire.

          The claimant shall submit its initial brief within 20 days from the 
appointment of the umpire. The respondent shall submit its brief within 20 days 
thereafter, and the claimant may submit a reply brief within 10 days after 
filing of the respondent's brief.

          The board shall make its decision with due regard to the custom and
usage of the insurance and reinsurance business. The board shall issue its
decision in writing based upon a hearing in which evidence may be introduced
without following strict rules of evidence but in which cross-examination and
rebuttal shall be allowed. The board shall make its decision within 60 days
following the termination of the hearings unless the parties consent to an
extension. The majority decision of the board shall be final and binding upon
all parties to the proceeding. Judgment may be entered upon the award of the
board in any court having jurisdiction thereof.

          If more than one Retrocessionaire is involved in the same dispute, all
such Retrocessionaires shall constitute and act as one party for purposes of
this Article, and communications shall be made by the Retrocedent to each of the
Retrocessionaires constituting the one party, provided that nothing therein
shall impair the rights of the Retrocessionaires to assert several, rather than
joint, defenses or claims, nor be construed as changing the liability of the
Retrocessionaires under the terms of this Agreement from several to joint.

          Each party shall bear the expense of its own arbitrator and shall
jointly and equally bear with the other party the expense of the umpire. The
remaining costs of the arbitration proceedings shall be allocated by the board.

/(1)/ Minority interest represents those shares in LaSalle Re Limited that are
      held as Exchangeable Non-Voting Shares. These shares are exchangeable, at
      the option of the holder, for Common Shares of the Company on a one-for-
      one basis.

/(2)/ Earnings per Common Share - assuming dilution equals income before
      minority interest and after preferred dividends declared and in
      arrears divided by the adjusted weighted average number of
      Common Shares outstanding.

/(3)/ The adjusted weighted average number of Common Shares outstanding include
      Common Shares and the Exchangeable Non-Voting Shares and the dilutive
      effect of stock options and stock appreciation rights using the treasury
      stock method.

/(4)/ Return on average equity is calculated by dividing net income before
      minority interest and after preferred dividends declared and in arrears by
      the average of the opening and closing sum of common shareholders' equity
      and minority interest. The adjustment in respect of the minority interest
      reflects the exchangeable nature of the Exchangeable Non-Voting Shares.

/(5)/ Book value per share is based on the sum of closing common shareholders'
      equity and minority interest divided by Common Shares and Exchangeable 
      Non-Voting Shares.
