NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
UNAUDITED

BASIS OF PRESENTATION

These condensed consolidated financial statements include the accounts of White
Mountains Insurance Group, Ltd. (the "Company") and its subsidiaries
(collectively, "White Mountains") and have been prepared in accordance with
accounting principles generally accepted in the United States of America
("GAAP"). The Company is a Bermuda corporation with its headquarters located at
Crawford House, 23 Church Street, Hamilton, Bermuda HM11. The Company's
principal executive office is located at 80 South Main Street, Hanover, New
Hampshire, 03755-2053 and its registered office is located at Clarendon House, 2
Church Street, Hamilton, Bermuda HMDX.

White Mountains' consolidated property and casualty insurance operations are
conducted primarily through OneBeacon Corporation ("OneBeacon", formerly CGU
Corporation), which was acquired by White Mountains on June 1, 2001. White
Mountains' consolidated property and casualty reinsurance operations are
conducted through Folksamerica Holding Company, Inc. ("Folksamerica").
Folksamerica also owns Peninsula Insurance Company ("PIC") and the run-off
operations of American Centennial Insurance Company ("ACIC") and British
Insurance Company of Cayman ("BICC").

All significant intercompany transactions have been eliminated in consolidation.
The financial statements include all adjustments considered necessary by
management to fairly present the financial position, results of operations and
cash flows of White Mountains. These interim financial statements may not be
indicative of financial results for the full year and should be read in
conjunction with the Company's 2000 Annual Report on Form 10-K, its Form 10-Q
for the period ended March 31, 2001 and its Form 8-K filed on June 25, 2001
which contains certain historical and pro forma financial information of White
Mountains and OneBeacon. The preparation of financial statements in conformity
with GAAP requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities as of the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Certain
amounts in the prior period financial statements have been reclassified to
conform with the current presentation. Amounts presented in the statement of
cash flows are shown net of balances acquired and sold in the purchase or sale
of the Company's consolidated affiliates.

DEFERRED CREDITS AND GOODWILL

As of June 30, 2001 and December 31, 2000, White Mountains had deferred credit
balances of $748.6 million and $92.2 million, respectively, and goodwill of
$23.8 million and $25.4 million, respectively. The deferred credits and goodwill
resulted principally from the acquisition activities outlined below.

On June 1, 2001 White Mountains acquired OneBeacon for $2,114.3 million in cash
and debt including related expenses. Because the cost of OneBeacon was less than
the fair value of its net identifiable assets acquired at that date, White
Mountains recorded a $682.0 million deferred credit at acquisition ($673.8
million at June 30, 2001) which is being amortized to income ratably over the
estimated period of benefit of seven years. See Note 2.

In May 2000 White Mountains acquired the reinsurance operations of Risk Capital
Reinsurance Company ("the Risk Capital Operations") for $20.3 million in cash
plus related expenses. Because the cost of the Risk Capital Operations was more
than the fair value of its net identifiable assets at that date, White Mountains
recorded $24.9 million of goodwill at acquisition ($22.1 million and $23.3
million at June 30, 2001 and December 31, 2000, respectively) which is being
amortized to income ratably over the estimated period of benefit of ten years.


-7-
In March 2000 White Mountains acquired PCA Property & Casualty Insurance Company
("PCA") for $122.3 million in cash. Because the cost of PCA was less than the
fair value of its net identifiable assets acquired at that date, White Mountains
recorded a $37.9 million deferred credit at acquisition ($29.9 million and $33.0
million at June 30, 2001 and December 31, 2000, respectively) which is being
amortized to income ratably over the estimated period of benefit of six years.

In October 1999 White Mountains acquired the International American Group
("IAG", which consisted primarily of PIC, ACIC and BICC) for $86.7 million in
cash. Because the cost of acquiring IAG was less than the value of its net
identifiable assets, the Company recorded a $62.0 million deferred credit at
acquisition ($26.7 million and $37.0 million at June 30, 2001 and December 31,
2000, respectively) which is being amortized to income ratably over the
estimated period of benefit of three years.

In June 1999 White Mountains acquired USF Re Insurance Co. ("USF Re") for total
consideration of $92.5 million. The purchase consideration included the issuance
of a $20.8 million, five-year note by White Mountains which was to be reduced by
adverse loss development post-acquisition. In response to USF Re adverse
development experienced by Folksamerica post-acquisition, the USF Re Note has
been reduced to zero at June 30, 2001 and December 31, 2000 and was carried at
$1.8 million at June 30, 2000.

In August 1998 White Mountains acquired Folksamerica. Because the cost of White
Mountains' investment in Folksamerica was less than the value of Folksamerica's
net identifiable assets at that date, White Mountains recorded a $39.8 million
deferred credit ($18.2 million and $22.2 million at June 30, 2001 and December
31, 2000, respectively) which is being amortized to income ratably over the
estimated period of benefit of five years.

As a result of a new accounting pronouncement recently issued, White Mountains
will recognize its entire unamortized deferred credit balance on January 1, 2002
as an extraordinary gain. See Note 5.

FOREIGN CURRENCY TRANSLATION

Folksamerica operates a branch office in Toronto, Canada to service its Canadian
customers and a portion of BICC's premiums are denominated in foreign
currencies. Net after tax losses from foreign currency translation of $1.0
million and $.7 million at June 30, 2001 and December 31, 2000, respectively,
were recorded in shareholders' equity as a component of accumulated other
comprehensive income. Changes in the values of Folkamerica's and BICC's
operations denominated in foreign currency, after tax, are reported on the
income and comprehensive income statement as a component of other comprehensive
net income.


NOTE 2. ACQUISITION OF ONEBEACON

On June 1, 2001, White Mountains acquired OneBeacon from London-based CGNU plc.
("CGNU") for $2,114.3 billion (the "Acquisition"), of which $260.0 million
consisted of a convertible note payable (the "Seller Note") with the balance
paid in cash. OneBeacon, which is headquartered in Boston, Massachusetts,
currently operates through property and casualty insurance companies licensed in
all 50 states. OneBeacon operates exclusively through a network of independent
insurance agents.

White Mountains and OneBeacon undertook a series of related pre-closing
transactions prior to the Acquisition. A summary of these transactions follow:


-8-
WHITE MOUNTAINS PRE-CLOSING TRANSACTIONS

DEBT TENDER AND DEBT ESCROW TRANSACTIONS

In April 2001 the Company completed a tender offer and consent solicitation for
$96.3 million in outstanding medium-term notes (the "Debt Tender") which
facilitated the Acquisition by amending the indenture governing the notes.
Pursuant to the Debt Tender, the Company repurchased and retired $90.9 million
of its medium-term notes and subsequently prepaid, in the form of a fully-funded
irrevocable escrow arrangement (the "Debt Escrow"), the balance of the
outstanding medium-term notes.

EQUITY FINANCING

On June 1, 2001, a small group of private investors purchased $437.6 million
of a newly-issued class of non-voting convertible preference shares of the
Company (the "Convertible Preference Shares"). The Convertible Preference
Shares bear an annual dividend of $2.00 per share and will be automatically
converted (at a conversion price of approximately $200.00) into 2,184,583
common shares of the Company ("Shares") upon approval by shareholders. If
shareholder approval has not been obtained prior to March 31, 2003, each
holder of Convertible Preference Shares will thereafter have the right to
require the Company to repurchase the Convertible Preference Shares on an "as
converted" basis at the then-current price of a Share. Since the market value
of Shares at June 30, 2001 ($376.25 per Share) exceeded the private
investors' cost of the Convertible Preference Shares (approximately $200.00
per Share), this instrument is deemed to have a beneficial conversion
feature. This determination requires that the Convertible Preference Shares
be marked-to-market, by an adjustment to retained earnings until the date the
Convertible Preference Shares are converted to permanent common equity (which
will occur upon shareholder approval, if and when such approval is obtained).

On June 1, 2001, Berkshire Hathaway, Inc. ("Berkshire") purchased from the
Company, for $75.0 million in cash, warrants (the "Warrants") to acquire
1,714,285 Shares at an exercise price of $175.00 per Share. Of the total
Warrants purchased by Berkshire, Warrants to purchase 1,170,000 Shares (the
"Series A Warrants") were immediately exercisable and Warrants to purchase
approximately 544,285 Shares (the "Series B Warrants") will become exercisable
upon approval by shareholders. If shareholder approval has not been obtained by
March 31, 2003, Berkshire will thereafter have the right to require the Company
to repurchase the Series B Warrants at a price per Series B Warrant equal to the
then-current market price per Share less $175.00. The Warrants have a term of
seven years from the date of issuance although the Company has the right to call
the Warrants for $60.0 million in cash commencing on the fourth anniversary of
their issuance. Since the Series B Warrants do not yet represent common equity
to the Company, they constitute a contingent put liability (similar in nature to
a stock appreciation right) which will be carried at fair value through a
periodic charge or credit to the income statement. The Series B Warrants will
become permanent common equity upon shareholder approval, if and when such
approval is obtained.

At the Company's 2001 Annual General Meeting of Shareholders to be held on
August 23, 2001, shareholders will vote on the issuance of additional Shares
upon conversion of the Convertible Preference Shares and upon the exercise of
the Series B Warrants.

On June 1, 2001, Berkshire also purchased for $225.0 million, $300.0 million in
face value of cumulative non-voting Preferred Stock (the "Berkshire Preferred
Stock") of a subsidiary of the Company. The Berkshire Preferred Stock is
entitled to a 2.35475% dividend per quarter and is mandatorily redeemable after
seven years. The Berkshire Preferred Stock represents subsidiary Preferred Stock
which is considered to be minority interest to the Company.

As previously mentioned, White Mountains received a total of $300.0 million in
cash from Berkshire in full payment for the Warrants and the Berkshire Preferred
Stock. The proceeds received were allocated to each instrument based on their
relative estimated fair values on June 1, 2001. As a result, $154.8 million of
such proceeds were allocated to the

-9-
Warrants and $145.2 million of such proceeds were allocated to the Berkshire
Preferred Stock. Of the amount initially allocated to the Warrants, a further
allocation was made among the Series A Warrants and the Series B Warrants of
$105.7 million and $49.1 million, respectively, based on the relative number
of Warrants in each series. In addition, White Mountains will accrete the
Berkshire Preferred Stock's recorded value to its face value of $300.0
million over the instrument's seven-year term through a charge to retained
earnings.

On June 1, 2001, Zenith Insurance Company purchased $20.0 million in cumulative
non-voting Preferred Stock (the "Zenith Preferred Stock") of a subsidiary of the
Company. The Zenith Preferred Stock is entitled to a 2.5% dividend per quarter
through June 30, 2007 and a 3.5% dividend thereafter and is mandatorily
redeemable after ten years. The Zenith Preferred Stock represents subsidiary
Preferred Stock which is considered to be minority interest to the Company.

On June 1, 2001, a subsidiary of the Company borrowed $700.0 million in term
loans and $125.0 million in revolving loans (of a $175.0 million revolving loan
facility) from a banking syndicate arranged by Lehman Brothers Inc.
(collectively the "Lehman Facility"). The term loans are repayable in quarterly
installments with a final maturity on the sixth anniversary of the closing date.
The revolving loan facility is available from the closing date until the fifth
anniversary of the closing. The loans are variable rate instruments which are
currently tied to a rate based on the three-month eurodollar rate.

SELLER NOTE

On June 1, 2001, White Mountains issued the Seller Note to CGNU. The Seller Note
has an eighteen month term and bears interest at a rate equal to 50 basis points
over the rate on White Mountains' revolving loan facility described above. The
Seller Note may be settled in cash, or at White Mountains' option, with Shares
valued at $245.00 per Share. White Mountains has classified this obligation as
debt since management believes it has the ability to settle this obligation in a
form other than pursuant to the Note Purchase Option Agreement which governs the
Seller Note.

ONEBEACON PRE-CLOSING TRANSACTIONS

OneBeacon also undertook a series of significant and related transactions prior
to the Acquisition. A summary of these transactions follow:

REINSURANCE CONTRACTS

Immediately prior to Acquisition, CGNU caused OneBeacon to purchase reinsurance
protection with National Indemnity Company (the "NICO Cover") for $1,114.8
million in cash. Pursuant to the NICO Cover, OneBeacon obtained $2.5 billion in
total coverage against its asbestos, environmental and certain other latent
exposures and ceded net nominal loss reserves of $747.6 million. Additionally,
immediately prior to Acquisition, CGNU caused OneBeacon to purchase reinsurance
protection with General Re Corporation (the "GRC Cover") for $275.0 million in
cash. Pursuant to the GRC Cover, OneBeacon obtained $400.0 million of adverse
development coverage and ceded $170.0 million of loss reserves. White Mountains
recorded a reinsurance recoverable pursuant to the GRC Cover of $267.0 million
as of June 30, 2001. National Indemnity Company and General Re Corporation are
wholly-owned subsidiaries of Berkshire.

The NICO Cover and the GRC Cover, which were contingent on, and occurred
contemporaneously with the Acquisition, are accounted for as prospective
reinsurance under the Emerging Issues Task Force Technical Matter Document No.
D-54 ("EITF Topic D-54") which characterizes the protection as an
indemnification by the seller for increases in the liabilities for losses and
loss adjustment expenses that existed at the acquisition date.

PRO FORMA FINANCIAL INFORMATION FOR THE ACQUISITION - SIX MONTHS ENDED
JUNE 30, 2001 AND 2000

The Acquisition was accounted for by the purchase method of accounting and,
therefore, the identifiable assets and liabilities of OneBeacon were recorded
by White Mountains at their fair values on June 1, 2001. The process of
determining the fair value of such assets and liabilities acquired, as
required under purchase accounting, was undertaken as follows: (i) the
purchase price of OneBeacon was preliminarily allocated to the acquired
assets and liabilities, based on their respective estimated fair values at
June 1, 2001; (ii) the excess of acquired net assets over the purchase price
was used to reduce the estimated fair values of all non-current,
non-financial assets acquired to zero; and (iii) the remaining excess of the
estimated fair value of net assets over the purchase price was recorded as a
deferred credit. The resulting purchase price allocation relating to the
OneBeacon acquisition, as shown below, is tentative and, as permitted under
purchase accounting principles, may be revised during the next twelve months.

The fair value of identifiable assets and liabilities acquired on June 1, 2001
were as follows (in $ millions):


<TABLE>
<S> <C>
Fair value of assets acquired ................ $ 11,895.1

Fair value of liabilities acquired ........... 9,098.8
------------

Fair value of net assets acquired ............ 2,796.3

Total purchase price, including expenses ..... (2,114.3)
------------

Resulting deferred credit .................... $ 682.0
============
</TABLE>

Significant assets and liabilities acquired through OneBeacon included $7,442.6
million of cash and investments, $2,448.9 million of reinsurance recoverable on
paid and unpaid losses, $1,267.3 million of insurance balances receivable,
$7,011.1 million of loss and loss adjustment expense and $1,897.7 million of
unearned insurance premiums.

Supplemental unaudited pro forma condensed combined income statement information

Additionally, such pro forma financial information is not expected to be
reflective of results that may occur in the future, particularly in light of
significant non-recurring transactions such as the NICO Cover and the GRC Cover
which are included therein. These transactions served to reduce revenues during
the 2001 and 2000 pro forma periods presented by approximately $1.5 billion and
$1.6 billion, respectively, and served to reduce net income available to
common shareholders by approximately $299.2 million and $266.1 million,
respectively.

====================================================================================
</TABLE>

(1) Reinsurance recoverable on unpaid losses acquired in the Acquisition were
$1,969.8 million.

Loss and loss adjustment expenses incurred during the period presented did not
include reserve strengthening for losses and loss adjustment expenses relating
to prior years.

In connection with purchase accounting for the Acquisition, White Mountains
reduced OneBeacon's loss and loss adjustment expense reserves and the related
reinsurance recoverables by $646.9 million and $346.9 million, respectively,
on OneBeacon's acquired balance sheet. This reduction to net loss and loss
adjustment expense reserves of $300.0 million will be accreted through an
income statement charge over the period that the claims are expected to be
settled of which $7.5 million was recognized for the one month period ended
June 30, 2001. The fair values of OneBeacon's loss and loss adjustment
expense reserves and related reinsurance recoverables acquired on June 1,
2001 were based on the present value of their expected cash flows with
consideration for the uncertainty inherent in both the timing of, and the
ultimate amount of, future payments for losses and receipts of amounts
recoverable from reinsurers. In estimating the fair value of such items,
management adjusted OneBeacon's nominal loss reserves (net of the effects of
reinsurance obtained from the NICO Cover and the GRC Cover) and discounted
them to their present value using an applicable risk-free discount rate. The
series of future cash flows related to such loss payments and reinsurance
recoveries were actuarially developed using OneBeacon's historical loss data.
The "price" for bearing the uncertainty inherent in OneBeacon's net loss
reserves was assumed to be approximately 11% of the present value of the
expected underlying cash flows of the loss reserves and reinsurance
recoverables, which is believed to be reflective of the cost OneBeacon would
likely incur if it had attempted to obtain reinsurance for the full amount of
its net loss and loss adjustment expense reserves with a third party
reinsurer.

The following table summarizes the loss and loss adjustment expense reserve
activities of White Mountains' other insurance and reinsurance operations for
the three months and six months ended June 30, 2001 and 2000:

======================================================================================================================
</TABLE>

(1) Reinsurance recoverable on unpaid losses acquired in the Risk Capital and
PCA transactions were $59.1 million and $153.3 million, respectively.

Incurred losses and loss adjustment expenses totaling $23.1 million for the six
months ended June 30, 2001 related to prior accident years primarily represent:
(i) higher than expected reported losses in Folksamerica's property excess line
recorded during the 2001 first quarter; and (ii) strengthening related to
business ceded to Imagine Re as part of a retroactive reinsurance agreement (the
"Imagine Cover") entered into during the 2000 fourth quarter. The offsetting
benefit resulting from the Imagine Cover has been deferred and will be
recognized into underwriting income over the expected settlement period of the
underlying claims in accordance with GAAP. Incurred reinsurance losses totalling
$13.3 million for the six months ended June 30, 2000, related to prior accident
years are primarily attributable to reserve additions resulting from USF Re and
asbestos, environmental liability and breast implant exposures.


NOTE 4. EARNINGS PER SHARE

Basic earnings per Common Share amounts are based on the weighted average number
of Shares outstanding. Diluted earnings per Common Share amounts are based on
the weighted average number of Shares and the net effect of dilutive equivalent
Shares outstanding. Since each of the 2000 and 2001 periods presented resulted
in a loss per Share, all equivalent Shares were deemed to be antidilutive to the
earnings per Share computations.

The following table outlines the Company's computation of earnings per Share for
the three months and six months ended June 30, 2001 and 2000:

Share and (ii) restricted Shares which are being expensed through the
income statement. The 2000 periods exclude the net anti-dilutive effects of
options to acquire 81,000 Shares at average prices ranging from $106.72 to
$108.32 per Share.


NOTE 5. ACCOUNTING STANDARDS RECENTLY ADOPTED AND ISSUED

Effective January 1, 2001, insurance companies domiciled in the United States
were required to adopt new regulations implementing a codification of statutory
accounting principles for insurers ("Codification"). The purpose of Codification
was to enhance the consistency of the accounting treatment of assets,
liabilities, reserves, income and expenses of insurers, by setting forth the
accounting practices and procedures to be followed in completing annual and
quarterly financial statements required by state law. Codification served to
increase the aggregate policyholders' surplus of White Mountains' insurance and
reinsurance operations.

In June 2001 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 142 entitled "Goodwill and Other
Intangible Assets". SFAS No. 142 sets forth new standards concerning accounting
for deferred credits, goodwill and other intangible assets arising from business
combinations.

With respect to deferred credits, SFAS No. 142 calls for the immediate
recognition of all existing and prospective deferred credits through the income
statement as an extraordinary gain. With respect to goodwill, SFAS No. 142 calls
for the amortization of existing and prospective goodwill only when the asset
acquired is deemed to have been impaired rather than systematically over a
perceived period of benefit.

SFAS No. 142 is effective for interim and annual periods beginning after
December 15, 2001. As a result, White Mountains will recognize its entire
unamortized deferred credit balance on January 1, 2002 as an extraordinary gain
and will no longer ratably amortize its unamortized goodwill balance at that
date. Unamortized deferred credits and goodwill as of June 30, 2001 totalled
$748.6 million and $23.8 million, respectively.

NOTE 6.  SEGMENT INFORMATION

Due to the significance of the Acquisition to the operations of White
Mountains, the Company is re-evaluating the organization of the financial
reporting of its operating segments. Historically, the Company organized its
operations into four operating segments (Reinsurance, Property and Casualty
Insurance, Investments in Unconsolidated Affiliates, and Holding Company).
During the 2001 second quarter, the Company determined that its Investments
in Unconsolidated Affiliates segment (which represented minority investments
in other property and casualty insurers) was no longer individually
significant to the presentation and has been reclassified as Property and
Casualty Insurance activities for all periods presented. The operations of
OneBeacon are contained in the Property and Casualty Insurance Segment for
the 2001 periods presented. The Company further expects the current
presentation to change in the future as the OneBeacon operations are more
thoroughly evaluated and organized into relevant operating segments.

The Company has made its current determination of segments based on
consideration of the following criteria: (i) the nature of the business
activities of each of the Company's subsidiaries and affiliates; (ii) the manner
in which the Company's subsidiaries and affiliates are organized; (iii) the
existence of primary managers responsible for specific subsidiaries and
affiliates; and (iv) the organization of information provided to the Company's
Board of Directors. There are no significant intercompany transactions among
White Mountains' segments other than occasional intercompany sales and transfers
of investment securities and intercompany service fees (all of which have been
eliminated herein). Investment results are included within the segment to which
the investments relate. During the 2000 fourth quarter, ACIC and BICC were
contributed to Folksamerica and are reported under the Reinsurance segment for
2001. During the 2001 second quarter, PIC was contributed to Folksamerica and is
reported under the Reinsurance segment for 2001. These changes in segment
reporting were not significant to the presentation, therefore, the Company has
not restated prior periods. Financial information presented by segment is shown
below:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS

RESULTS OF OPERATIONS-- THREE MONTHS AND SIX MONTHS ENDED JUNE 30, 2001 AND 2000

White Mountains reported a net loss available to common shareholders of $92.8
million or $15.80 per Share for the six months ended June 30, 2001, compared to
a net loss of $5.8 million or $.97 per Share for the comparable 2000 period.
White Mountains comprehensive net loss available to common shareholders, which
includes other comprehensive income items (primarily changes in net unrealized
investment gains for the period), was $141.4 million or $24.06 per Share for the
six months ended June 30, 2001, compared to comprehensive net income of $38.6
million or $6.54 per Share for the comparable 2000 period.

White Mountains reported a net loss available to common shareholders of $109.9
million or $18.71 per Share for the three months ended June 30, 2001, compared
to a net loss of $.2 million or $.03 per Share for the comparable 2000 period.
White Mountains' comprehensive net loss available to common shareholders was
$141.5 million or $24.09 per Share for the three months ended June 30, 2001,
compared to comprehensive net income of $6.4 million or $1.08 per Share for the
comparable 2000 period.

-16-
The Company ended the second quarter of 2001 with a tangible book value per
Share (which includes unamortized deferred credits less goodwill per Share)
of $202.83, an increase of $17.39 from the March 31, 2001 value of $185.44.
Assuming shareholder approval of the issuance of additional Shares upon
conversion of the Convertible Preference Shares and upon the exercise of the
Series B Warrants, the fully converted tangible book value per Share at June
30, 2001 would have been $247.34, an increase of $61.90 from the March 31,
2001 value. The increase in fully converted tangible book value per Share
from March 2001 to June 2001 period resulted primarily from the June 1, 2001
acquisition of OneBeacon at an amount less than the underlying fair value of
the net assets acquired.

INSURANCE AND REINSURANCE OPERATIONS

ONEBEACON. OneBeacon reported a $48.0 million comprehensive net loss during the
one month ended June 30, 2001, which consisted of $31.9 million in losses from
operations and $16.1 million of after tax unrealized losses, primarily on
OneBeacon's sizable fixed maturity portfolio. The unrealized losses resulted
from an increase in long-term interest rates during the period. A summary of
OneBeacon's underwriting results for the one-month period ended June 30, 2001
follows:

<TABLE>
<CAPTION>

GAAP Ratios:
Loss and loss adjustment expense ...................... 94%
Underwriting expense .................................. 32%
-------------
Combined ratio ................................ 126%
==============================================================================
</TABLE>

OneBeacon's earned premiums during June reflect reduced writings on historically
unprofitable product lines. OneBeacon's combined ratio for the one month period
included approximately 10 points attributable to catastrophes, primarily storms
in the mid-west and certain gulf-coast regions (CAT's 44 and 45). Despite the
storm-related losses incurred in June by OneBeacon, the underwriting results of
OneBeacon presented herein are worse than the loss experience that White
Mountains expects of OneBeacon over time. Since the Acquisition, White Mountains
has been focused on strengthening OneBeacon's future operations through more
selective and disciplined underwriting practices, the implementation of price
increases, the elimination of poor and marginal accounts and agents and improved
claims handling. Such actions are expected to yield improved underwriting
results on lower premium writings. Subsequent improvements to the operating
results of OneBeacon, to the extent they are attained, will not emerge until a
significant amount of OneBeacon's policies in-force are renewed on revised
terms.

FOLKSAMERICA. Folksamerica reported a $24.3 million comprehensive net loss
during the first half of 2001 versus $12.3 million of comprehensive net income
for the comparable 2000 period. Unrealized investment losses provided $16.0
million of its comprehensive net loss during the first half of 2001 compared to
$5.8 million of unrealized investment gains for the comparable 2000 period.
Folksamerica reported a $13.3 million comprehensive net loss during the second
quarter of 2001 versus $10.0 million of comprehensive net income for the
comparable 2000 period. The reduction in Folksamerica's after tax unrealized
investment gains, particularly during the 2001 second quarter, resulted from an
increase in long-term interest rates which adversely impacted the value of its
fixed maturity portfolio during the period.

===================================================================================================
</TABLE>

Folksamerica's significant increases in written and earned premiums during the
2001 periods is primarily attributable to improved terms and conditions in the
overall reinsurance market for 2001 as well as its second quarter 2000
acquisition of the Risk Capital Operations.

Folksamerica's combined ratio of 116% for the first half of 2001 included higher
than expected reported losses in Folksamerica's property excess line which were
recorded during the 2001 first quarter. Folksamerica's combined ratio of 112%
for the first half of 2000 included adverse development associated with the
acquired reserves of USF Re recorded principally during the 2000 second quarter.
Folksamerica's combined ratio of 111% for the second quarter of 2001 was
significantly improved from the 121% recorded during the 2001 first quarter.

Folksamerica's 2001 GAAP combined ratios do not take into account the
favorable economic impact of Folksamerica's Imagine Cover which totalled
$30.8 million at June 30, 2001. Adverse development on reserves covered under
the Imagine Cover are recorded currently and are therefore included in
Folksamerica's 2001 combined ratio. However, the reinsurance benefit obtained
from the Imagine Cover is deferred and recognized into underwriting income
over the expected settlement period of the underlying claims in accordance
with GAAP. Folksamerica estimates that the favorable impact of the Imagine
Cover, if reportable in the current period, would have reduced Folksamerica's
combined ratio for the three and six months ended June 30, 2001 to 106% and
112%, respectively. Folksamerica's 2000 GAAP combined ratios do not take into
account the favorable impact of offsetting USF Re purchase price adjustments
which are recorded at its parent. Folksamerica estimates that these benefits
recorded during the 2000 first half would have served to reduce
Folksamerica's combined ratio to approximately 109%.

OTHER INSURANCE OPERATIONS. In addition to the operations of OneBeacon and
Folksamerica, White Mountains also had earned premiums of $12.3 million and
$10.9 million, principally related to the operations of PIC, for the six
month periods ended June 30, 2001 and 2000, respectively. PIC's GAAP combined
ratio during those periods was 104% and 98%, respectively. PIC's earned
premiums for the three month periods ended June 30, 2001 and 2000 totalled
$6.4 million and $5.3 million.

On January 5, 2001, the Company completed the sale of its wholly-owned insurance
subsidiary, Waterford Insurance Company ("WIC"), to a third party for $23.6
million of cash proceeds net of transaction expenses. The Company recognized an
after tax gain on the sale of WIC of $11.4 million. WIC ceased actively writing
insurance during 1999.

INVESTMENT OPERATIONS

Net investment income totalled $82.2 million for the six months ended June 30,
2001 compared to $35.0 million for the comparable 2000 period. Net investment
income totalled $58.2 million for the three months ended June 30, 2001 compared
to $20.5 million for the comparable 2000 period. White Mountains' investment
income is comprised primarily of interest income associated with its fixed
maturity and short-term investments and dividend income from its equity
investments. The increases in net investment income from the 2001 to 2000
periods are primarily attributable to the Acquisition and the inclusion of the
full-period investment results of PCA and the Risk Capital Operations which were
acquired during the 2000 first half.

White Mountains records net unrealized investment gains and losses as a result
of changes in the value of its available for sale investment portfolio holdings
and changes in its net unrealized investment gains and losses resulting from
various investments in unconsolidated insurance affiliates which are recorded in
other assets.

Additional information concerning White Mountains' ending net unrealized
investment gains and losses recorded on its balance sheet were as follows:

</TABLE>

The $19.9 million decrease in after tax net unrealized gains during the 2001
first half resulted principally from an increase in long-term interest rates,
particularly during the 2000 second quarter, which served to reduce the market
value of White Mountains' sizable fixed maturity portfolio. The $43.0 million
increase in after tax net unrealized gains during the 2000 first half included
$40.1 million of after tax unrealized gains recorded in connection with the
Company's former investment in Financial Security Assurance Holdings Ltd.
("FSA"). The value of White Mountains' investment in FSA rose substantially
during the 2000 first half after the announcement that it was to be acquired by
Dexia S.A. during the 2000 third quarter.

-19-
Net gains on investments of $33.3 million for the six months ended June 30, 2001
resulted principally from second quarter sales of fixed maturity investments at
Folksamerica and second quarter sales of common stocks at the holding company.
Net losses on investments of $4.6 million for the six months ended June 30, 2000
resulted principally from first quarter sales of fixed maturities in preparation
for Folksamerica's acquisitions of PCA and the Risk Capital Operations.

EXPENSES AND TAXES

Losses and loss adjustment expenses totalled $500.7 million for the 2001 first
half ($410.5 million for the 2001 second quarter) versus $160.3 million for the
comparable 2000 period ($107.3 million for the 2000 second quarter). Insurance
and reinsurance acquisition expenses totalled $120.7 million for the first half
of 2001 ($97.7 million for the 2001 second quarter) versus $50.3 million for the
first half of 2000 ($32.4 million for the 2000 second quarter). The increases in
these insurance expenses from the 2001 to 2000 periods is primarily attributable
to the Acquisition.

General and administrative expenses totalled $100.4 million for the first half
of 2001 ($77.2 million for the 2001 second quarter) versus $32.8 million for the
comparable 2000 period ($17.2 million for the 2000 second quarter). The increase
in compensation and benefits expenses from the 2001 to 2000 periods is primarily
attributable to the Acquisition and, to a lesser extent, from an increase in
various Share-based contingent compensation accruals. White Mountains increased
its contingent compensation accruals during the 2001 first half in anticipation
of above-plan results for certain performance share cycles as well as an
increase in the market value of Shares during the period.

The Share appreciation expense for Series B Warrants of $78.1 million
recorded during the 2001 periods represents the excess of the estimated fair
value of the Series B Warrants of $127.3 million over the purchase price
allocation to the Series B Warrants. Until shareholders approve the issuance
of Shares upon exercise of the outstanding Series B Warrants, the Series B
Warrant obligation constitutes a contingent put liability (similar in nature
to a stock appreciation right) which will be carried at fair value through
the date of shareholder approval through a periodic charge or credit to the
income statement.

Interest expense totalled $8.4 million for the first half of 2001 ($6.5 million
for the 2001 second quarter) versus $8.2 million for the comparable 2000 period
($4.1 million for the 2000 second quarter). The increase in interest expense
during the 2001 periods resulted from one-month of borrowings under the Lehman
Facility and the Seller Note, offset slightly by reduced interest expense
resulting from the Debt Tender and the Debt Escrow transactions.

Accretion of discounted loss and loss adjustment expense reserves of $7.5
million recorded during the 2001 periods represents one-month of amortization of
net loss and loss adjustment expense reserves (which were reduced by a net value
of $300.0 million to their estimated fair value in purchase accounting in
connection with the Acquisition). The accretion expense recorded during the 2001
period was based on an estimate of the period over which OneBeacon's loss and
loss adjustment expense reserves are expected to be settled.

As a result of the Company's redomestication to Bermuda in 1999, income earned
by its offshore subsidiaries in subsequent periods is generally subject to an
effective overall tax rate lower than that imposed by the United States,
however, no tax benefits will be attained in the event of losses incurred by
such companies. Income earned by the Company's onshore subsidiaries continues to
be subject to United States income taxes. During the 2001 first half, White
Mountains recorded a $24.4 million tax benefit which consisted of a Federal and
state income tax benefit of $23.4 million and a foreign and United States
withholding tax benefit of $1.0 million related to prior year accruals. During
the 2000 first half, White Mountains recorded a $1.2 million tax provision which
consisted of a Federal and state income tax provision of $.4 million and a
foreign and United States withholding tax provision of $.8 million.

-20-
During the 2001 second quarter, the Company recorded a $4.8 million
extraordinary loss on extinguishment of debt in connection with the Debt
Tender and the Debt Escrow. The medium-term notes were an obligation of the
Company which is domiciled in Bermuda. As a result, no Federal income tax
benefit was recorded by the Company for the Debt Tender and the Debt Escrow.

LIQUIDITY AND CAPITAL RESOURCES

The primary sources of cash inflows for the Company and certain of its
intermediary holding companies are investment income, sales of investment
securities and dividends received from its operating subsidiaries. Under the
insurance laws of the states and countries under which the holding companies of
White Mountains' insurance subsidiaries are domiciled, an insurer is restricted
with respect to the timing or the amount of dividends it may pay without prior
approval by regulatory authorities. Accordingly, there is no assurance regarding
the amount of such dividends that may be paid by such subsidiaries in the
future.

On January 5, 2001, White Mountains completed the sale of WIC to a third party
for consideration of $23.6 million in cash, net of transaction related expenses.

In March 2001 the Company declared and paid an annual dividend of $5.9 million
to its common shareholders.

In February 2001 the Company issued 21,000 restricted Shares to its key
employees which vest fully in December 2002. In June 2001 the Company issued
73,500 restricted Shares to its key employees which vest fully in June 2003.

In April 2001 the Company paid $100.6 million in cash to complete the Debt
Tender and to establish the Debt Escrow. Completion of the Debt Tender permitted
the Company to effect an amendment to the indenture governing the notes which
facilitated the Acquisition.

On June 1, 2001, White Mountains acquired OneBeacon for cash and the Seller
Note. The total consideration paid for OneBeacon was $2,114.3 million, including
related expenses. Significant assets and liabilities acquired through OneBeacon
included $7,442.6 million of cash and investments, $2,448.9 million of
reinsurance recoverable on paid and unpaid losses, $1,267.3 million of insurance
balances receivable, $7,011.1 million of loss and loss adjustment expenses and
$1,897.7 million of unearned insurance premiums.

On June 1, 2001, White Mountains issued the Seller Note to CGNU. The Seller Note
has an eighteen month term and bears interest at a rate equal to 50 basis points
over the rate on White Mountains' revolving loan facility described above. The
Seller Note may be settled in cash, or at White Mountains' option, with Shares
valued at $245.00 per Share. White Mountains has classified this obligation as
debt since management believes it has the ability to settle this obligation in a
form other than pursuant to the Note Purchase Option Agreement which governs the
Seller Note.

In connection with the acquisition of OneBeacon, White Mountains entered into
the following capital raising activities during the 2001 second quarter: (i) the
issuance of the Convertible Preference Shares for $437.6 million; (ii) the
issuance of the Warrants for $75.0 million; (iii) the issuance of the Berkshire
Preferred Stock and the Zenith Preferred Stock for a total of $245.0 million;
and (iv) $825.0 million in borrowings under the Lehman Facility.

-21-
At the 2001 Annual General Meeting of Shareholders to be held on August 23,
2001, shareholders will vote on the issuance of additional Shares upon
conversion of the Convertible Preference Shares and upon the exercise of the
Series B Warrants. Had shareholder approval for this matter been obtained as of
June 30, 2001, the Company's total shareholders' equity would have increased
$949.3 million to $1,570.2 million, its fully converted Shares outstanding would
have increased by 2,728,868 Shares to a total of 9,931,351 Shares and its fully
converted tangible book value per Share would have increased $44.51 to $247.34.

Absent shareholder approval of the Convertible Preference Share and Series B
Warrant proposal described above, White Mountains may be required to pay cash,
at the then market value of Shares, for any Convertible Preference Shares
converted or Series B Warrants exercised after March 31, 2003, or upon the
redemption of the Convertible Preference Shares on June 1, 2011. Conversions,
exercises or redemptions for cash could create a strain on White Mountains'
existing or future cash resources. Further, if White Mountains were to borrow
additional monies for such redemptions, its debt to equity ratios could increase
to a level higher than it currently prefers to operate.

On June 30, 2001, White Mountains paid a total of $2.7 million in dividends to
holders of the Convertible Preference Shares, the Berkshire Preferred Stock and
the Zenith Preferred Stock.

As of June 30, 2001, White Mountains' portion of the Lehman Facility due within
the next twelve months totalled $63.1 million.

During the first quarter of 2000, White Mountains raised $196.3 million through
sales of investment securities (primarily fixed maturity investments) in
preparation for its acquisitions of PCA and the Risk Capital Operations.

On March 31, 2000, White Mountains acquired PCA for consideration of $122.3
million in cash. Significant assets and liabilities acquired through PCA
included $339.8 million of cash and investments, $160.0 million of reinsurance
recoverables and $405.5 million of loss and loss adjustment expense reserves.

On May 5, 2000, White Mountains acquired the Risk Capital Operations for
consideration of $20.3 million in cash plus related expenses. Significant
assets and liabilities acquired with the Risk Capital Operations included
$249.9 million of cash and investments, $108.6 million of premiums
receivable, $312.5 million of net loss and loss adjustment expense reserves
and $92.9 million of net unearned reinsurance premiums. In addition, the Risk
Capital Operations provided White Mountains with two specialty underwriting
units (Accident & Health and Marine) and several significant new treaty
clients.

White Mountains made significant acquisitions of run-off insurance portfolios
during 1999 and 2000. These transactions involved the assumption of sizable
portfolios of invested assets on favorable terms, as well as the assumption of
insurance liabilities. Run-off liabilities paid are shown on White Mountains'
statement of cash flows as uses of operating cash whereas sales of the related
assets acquired are shown as sources of cash from investing activities.


FORWARD LOOKING STATEMENTS

White Mountains relies upon the safe harbor for forward looking statements
provided by the Private Securities Litigation Reform Act of 1995. This safe
harbor requires that White Mountains specify important factors that could cause
actual results to differ materially from those contained in forward-looking
statements made by or on behalf of White Mountains. Accordingly, forward-looking
statements by the Company and its affiliates are qualified by reference to the
following cautionary statements.

-22-
In its filings with the Securities and Exchange Commission, reports to
shareholders, press releases and other written and oral communications, White
Mountains from time to time makes forward-looking statements. Such
forward-looking statements include, but are not limited to, (i) projections of
revenues, income (or loss), earnings (or loss) per Share, dividends, market
share or other financial forecasts, (ii) statements of plans, objectives or
goals of White Mountains or its management, including those related to growth in
book value and deferred credit per Share or return on equity and (iii) expected
losses on, and adequacy of loss reserves for, insurance in force. Words such as
"believes", "anticipates", "expects", "intends" and "plans" and similar
expressions are intended to identify forward-looking statements but are not the
exclusive means of identifying such statements.

White Mountains cautions that a number of important factors could cause actual
results to differ materially from the plans, objectives, expectations, estimates
and intentions expressed in forward-looking statements made by White Mountains.
These factors include: (i) competitive forces, including the conduct of other
property and casualty insurers and reinsurers, (ii) changes in domestic or
foreign laws or regulations applicable to White Mountains, its competitors or
its clients, (iii) an economic downturn or other economic conditions (such as a
rising interest rate environment) adversely affecting White Mountains' financial
position, and (iv) loss reserves and other balance sheet items established by
White Mountains subsequently proving to have been inadequate. White Mountains
cautions that the foregoing list of important factors is not exhaustive. In any
event, such forward-looking statements made by White Mountains speak only as of
the date on which they are made, and White Mountains does not undertake any
obligation to update or revise such statements as a result of new information,
future events or otherwise.


ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

White Mountains' consolidated balance sheet includes a substantial amount of
assets and liabilities whose fair values are subject to market risk. The term
market risk refers to the risk of loss arising from adverse changes in: interest
rates and other relevant market rates and prices. Due to White Mountains'
sizable balances of interest rate sensitive instruments, market risk can have a
significant effect on White Mountains' consolidated financial position.

INTEREST RATE RISK

FIXED MATURITY PORTFOLIO. In connection with the Company's consolidated
insurance and reinsurance subsidiaries, White Mountains invests in interest rate
sensitive securities, primarily debt securities. White Mountains' strategy is to
purchase fixed maturity investments that are attractively priced in relation to
perceived credit risks. White Mountains' investments in fixed maturity
investments are held as available for sale and, accordingly, in accordance with
SFAS No. 115 these investments are carried at fair value on the balance sheet
with unrealized gains reported net of tax in a separate component of
shareholders equity. White Mountains generally manages its interest rate risk
associated with its portfolio of fixed maturity investments by monitoring the
average duration of the portfolio which allows White Mountains to achieve an
adequate yield without subjecting the portfolio to an unreasonable level of
interest rate risk. White Mountains' fixed maturity portfolio is comprised of
primarily investment grade corporate securities, U.S. government and agency
securities, municipal obligations and mortgage-backed securities (i.e. those
receiving a rating from the National Association of Insurance Commissioners of
1 or 2).

Increases and decreases in prevailing interest rates generally translate into
decreases and increases in fair values of fixed maturity investments,
respectively. Additionally, fair values of interest rate sensitive instruments
may be affected by the credit worthiness of the issuer, prepayment options,
relative values of alternative investments, the liquidity of the instrument and
other general market conditions. Since June 30, 2001, White Mountains has sold
approximately $1.0 billion of its mortgage-backed securities and has reinvested
the proceeds primarily in short-term investments. One result of this action has
been to reduce White Mountains' interest rate risk as of the date of this report
from the level of interest rate risk that existed at June 30, 2001.

-23-
INDEBTEDNESS. White Mountains utilized a significant amount of variable rate
debt financing (the Lehman Facility and the Seller Note) in connection with the
Acquisition. Increases and decreases in prevailing interest rates will translate
into increases and decreases in the future interest expense associated with this
indebtedness although the carrying value of such liabilities will not be
effected. At June 30, 2001, White Mountains also had $8.3 million in fixed rate
indebtedness outstanding of which a substantial portion was prepaid in
connection with the Acquisition, therefore, its fair value is not subject
to future changes in prevailing interest rates.

During the 2001 second quarter White Mountains entered into a ten-year,
$200.0 million notional interest rate swap with a large investment bank. The
interest rate swap was undertaken to achieve a fixed interest rate on a
portion of the Lehman Facility. Pursuant to SFAS No. 133, this investment is
carried at fair value on the balance sheet ($1.1 million at June 30, 2001)
with changes in its fair value reported directly through the income statement
as it does not qualify for hedge accounting since its duration is dissimilar
to that of the Lehman Facility. White Mountains may undertake additional
transactions of this nature in the future.

The table below summarizes the estimated effects of hypothetical increases and
decreases in market interest rates on White Mountains' fixed maturity portfolio
and the interest rate swap.

(1) The relevant interest rate for the assumed change in White Mountains' fixed
income portfolio and interest rate swap is predicated upon assumed changes in
the ten-year U. S. Treasury yield.


EQUITY PRICE RISK

The carrying values of White Mountains' common equity securities, its other
investments, its Convertible Preference Shares and its contingent liability for
Series B Warrants outstanding are based on quoted market prices or management's
estimates of fair value (which is based, in part, on quoted market prices) as of
the balance sheet date. Market prices of common equity securities, in general,
are subject to fluctuations which could cause the amount to be realized upon
sale or exercise of the instruments to differ significantly from the current
reported value. The fluctuations may result from perceived changes in the
underlying economic characteristics of the investee, the relative price of
alternative investments, general market conditions and supply and demand
imbalances for a particular security.

On August 23, 2001, shareholders will vote on the issuance of additional Shares
upon conversion of the Convertible Preference Shares and upon the exercise of
the Series B Warrants. Upon shareholder approval, the Convertible Preference
Shares and the contingent liability for Series B Warrants will no longer
constitute obligations of the Company subject to equity price risk.


FOREIGN CURRENCY EXCHANGE RATES

A small portion of White Mountains' reinsurance assets are denominated in
foreign currencies. Net unrealized foreign currency translation gains and losses
are reported, after tax, as a net amount in a separate component of
shareholders' equity. Changes in the values of these assets due to currency
fluctuations, after tax, are reported on the income statement as a component of
other comprehensive net income. White Mountains' net assets denominated in
foreign currency are not material.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

None.

ITEM 2. CHANGES IN SECURITIES

On June 1, 2001, White Mountains completed its acquisition of
OneBeacon. In connection with the Acquisition, the Company raised
$437.6 million through the issuance of 2,184,583 Convertible
Preference Shares and $75.0 million from the issuance of 1,714,285
Warrants. The Company used the proceeds from these equity issuances
to partially fund the Acquisition.

The Convertible Preference Shares are convertible into 2,184,583
Common Shares upon shareholder approval. Similarly, the Company
issued the Warrants in two series, the Series A Warrants consisting
of warrants to acquire 1,170,000 Common Shares and the Series B
Warrants consisting of warrants to acquire 544,285 Common Shares. The
Series A Warrants have terms comparable to the Series B Warrants,
except that they are currently exercisable for Common Shares. The
Series B Warrants are not exercisable until shareholders approve such
exercise. The Company will seek shareholder approval for the
conversion of the Convertible Preference Shares and the issuance of
Common Shares upon the exercise of the Series B Warrants at the 2001
Annual General Meeting of Shareholders to be held on August 23, 2001.
Upon approval by shareholders, each Convertible Preference Share will
be repurchased and cancelled by the Company in consideration of the
issuance of one Common Share and the Series B Warrants may be
exercised, beginning immediately, for Common Shares.

The Convertible Preference Shares and the Warrants have not been and
will not be registered under the Securities Act of 1933. These
securities were offered privately to accredited investors as provided
under Rule 506 to Regulation D of the Securities Act of 1933. The
Company sold the Convertible Preference Shares and Warrants directly
to private investors, therefore, no underwriter was used in
connection with the offerings.

The following summarizes the principal features of the Convertible
Preference Shares and the Warrants:

CONVERTIBLE PREFERENCE SHARES

DIVIDENDS. Holders of Convertible Preference Shares, when and as
declared by the Board out of the net profits or net assets of the
Company legally available for payment under Bermuda Law, are entitled
to receive cumulative dividends payable in cash at the annual rate of
$2.00 per share, payable semi-annually beginning on June 30, 2001.
Past due and unpaid dividends will accrue an additional dividend at
an annual rate of 1% compounded each year. The Company will not
declare or pay dividends on its Common Shares as long as dividends on
the Convertible Preference Shares are past due and unpaid.

CONVERSION. Upon receipt of shareholder approval, Conversion will
occur at a conversion price of $200.00 per share, subject to certain
standard anti-dilution adjustments for issuances of and distributions
on Common Shares. After March 31, 2003, and absent shareholder
approval, each Convertible Preference Share is convertible into cash
equal to the then fair market value of each Common Share.

REDEMPTION. Any Convertible Preference Shares outstanding on June 1,
2011 will be redeemed by the Company for $200.00 in cash per share,
plus all accrued dividends as of such date.

-25-
VOTING. The holders of the Convertible Preference Shares have no
voting rights EXCEPT for any voting rights provided in the Company's
Bye-laws or required by the Companies Act, 1981. In addition, the
Company shall not amend, alter or repeal its Memorandum of
Continuance, Bye-laws or the terms and conditions of the Convertible
Preference Shares in a manner that adversely affects the rights of
the Convertible Preference Shares without first obtaining the consent
or approval of at least two-thirds of the then-outstanding
Convertible Preference Shares.

LIQUIDATION. In the event of any liquidation, dissolution, or winding
up of the Company, holders of the Convertible Preference Shares are
entitled to receive payment of $50.00 per share plus all accrued
dividends before any distribution is made to holders of Common
Shares.

RESTRICTIONS ON TRANSFER. Convertible Preference Shares can only be
transferred, except to the extent required by applicable law, (i)
with the prior written consent of the Company, which consent shall
not be unreasonably withheld, (ii) by any initial holder to one of
its affiliates or (iii) to the Company or any initial holder of
Convertible Preference Shares. The Convertible Preference Shares have
not been registered under the Securities Act of 1933 and may not be
offered or sold in the United States or to any citizen or resident of
the United States in absence of a valid registration of the
Securities Act of 1933 except in reliance on an exemption from the
registration requirements. Additionally, transfers of Convertible
Preference Shares may also be subject to approval of the Bermuda
Monetary Authority.

REGISTRATION RIGHTS. Subject to certain limitations, holders of the
Convertible Preference Shares are entitled to up to three demand
registration rights (in the aggregate) and unlimited piggyback rights
for the registration of the Common Shares issued upon Conversion.

WARRANTS

EXERCISE. The Series B Warrants entitle the holder thereof to
purchase 544,285 Common Shares at a price of $175.00 per share,
subject to certain standard anti-dilution adjustments for issuances
of and distributions on Common Shares. The Series B Warrants become
